                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)

1. ORGANIZATION, RELATIONSHIP WITH LESSEE AND BASIS OF PRESENTATION

Organization:

        Sunstone Hotel Investors, Inc., a Maryland corporation (the "Company" or
"Sunstone"), was formed in September 1994 and commenced operations as a real
estate investment trust ("REIT") on August 15, 1995. At September 30, 1999, the
Company had a 94.8% interest in Sunstone Hotel Investors, L.P. (the "Operating
Partnership") which also commenced operations in August 1995. The Company
conducts all of its business through and is the sole general partner of the
Operating Partnership.

        At September 30, 1999, the Company's portfolio included 59 hotel
properties, primarily located in the western United States, all of which are
leased to Sunstone Hotel Properties, Inc. (the "Lessee") under operating leases
(the "Percentage Leases") that provide for the payment of base and percentage
rent. The Lessee is owned by Robert A. Alter, Chairman, Chief Executive Officer
and President of the Company (80%), and Charles L. Biederman, Vice Chairman and
Executive Vice President of the Company (20%). The Lessee has entered into a
management agreement pursuant to which all of the hotels are managed by Sunstone
Hotel Management, Inc. (the "Management Company"), of which Mr. Alter is the
sole shareholder.

Relationship with Lessee:

        The Company must rely solely on the Lessee to generate sufficient cash
flow from the operation of the hotels to enable the Lessee to meet its
substantial rent obligation to the Company under the Percentage Leases. The
Lessee has incurred significant losses from its inception in 1995. At September
30, 1999, the Lessee's stockholder's deficit amounted to $10.9 million. At
September 30, 1999, the Lessee's rent payable to the Company amounted to $13.8
million. Also at September 30, 1999, the Lessee's current liabilities exceeded
its current assets by $10.2 million. The ability of the Lessee to fund its daily
operations and continue to remain current on its substantial rent obligation to
the Company is a result of the original terms under the Percentage Leases, for
the payment of rent to the Company, which allow monthly base rent to be paid in
arrears and monthly percentage rent to be paid within 45 days after the
respective month end. The Company's management will continue to evaluate the
financial condition of the Lessee and continue to evaluate other factors
regarding the relationship between the Company and the Lessee.

Basis of Presentation:

        The consolidated financial statements include the accounts of the
Company and its subsidiaries, including the Operating Partnership. All
significant intercompany transactions and balances have been eliminated.

        The interim consolidated financial statements of the Company have been
prepared without audit in accordance with generally accepted accounting
principles for interim information and with the instructions for Form 10-Q and
Article 10 of Regulation S-X. Accordingly, they do not include all of the
information and footnotes required by generally accepted accounting principles
for complete financial statements. The Company believes that the disclosures are
adequate to make the information presented not misleading when read in
conjunction with the audited consolidated financial statements included in the
Company's Annual Report on Form 10-K for the year ended December 31, 1998 and
Quarterly Reports on Form 10-Q for prior quarters of 1999. The financial
information presented herein reflects all adjustments, consisting only of normal
recurring accruals, which are, in the opinion of management, necessary for a
fair presentation of the results

for the interim periods presented. The results for the three and nine months
ended September 30, 1999 are not necessarily indicative of the results to be
expected for the year ended December 31, 1999.

Use of Estimates

        The preparation of 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 at the
date of the financial statements and the reported amounts of revenues and
expenses during the reporting periods. Significant estimates made in preparing
the consolidated financial statements include the collectibility of rent
receivable, the recoverability of long-lived assets and the outcome of claims,
litigation and other contingencies (see Notes 2 and 6); actual results could
differ materially from those estimates in the near term.

Seasonality:

        The hotel industry is seasonal in nature. Seasonal variations in
occupancy at the Company's hotels may cause quarterly fluctuations in the
Company's lease revenues.

2. ACQUISITION OF SUNSTONE

        On April 5, 1999, the Company received a merger offer from SHP
Acquisition, LLC ("SHP"), certain management personnel of the Lessee and
Westbrook Funds III. The Lessee leases and operates all of the Company's hotels
and is owned by Robert A. Alter, Chairman and Chief Executive Officer of the
Company and Charles L. Biederman, Vice Chairman and Executive Vice President of
the Company. Westbrook Partners LLC is a New York based real estate opportunity
fund, which is a 9.6% stockholder in the Company, whose managing principal, Paul
Kazilionis, is a director of the Company. The original offer to purchase was for
all the common stock of the Company at $9.50 to $10.00 in cash per share.

        Upon receiving the SHP merger offer, the Company formed the Special
Committee of the Board of Directors, comprised of all the independent members of
the Board of Directors, to study the proposal and consider the Company's
alternatives. The Special Committee was advised by Goldman, Sachs & Co. and
Altheimer & Gray.

        Upon the recommendation of the Special Committee of the Board of
Directors of the Company and the approval of the Board of Directors, Sunstone
entered into a merger agreement (the "Merger Agreement" or the "Merger") as of
July 12, 1999 with SHP, an affiliate of Westbrook Partners LLC and certain
members of Sunstone's senior management. Under the terms of the Merger Agreement
each share of common stock of the Company will be exchanged for $10.35 in cash,
subject to adjustments which management currently anticipates will increase the
merger consideration to approximately $10.39 per share. The adjustments provide
that common stockholders will be paid a proportionate share of $2.5 million, or
approximately $0.06 per share. The Merger Agreement also provides for a possible
decrease in the event certain transaction expenses, consent payments or other
payments exceed amounts specified in the Merger Agreement. Management currently
anticipates that these adjustments will result in a decrease of approximately
$0.02 per share. The net result of all the adjustments is currently anticipated
to increase the merger consideration by approximately $0.04 per share to
approximately $10.39 per share. The actual amount of the adjustments will not be
determined until shortly prior to the closing of the Merger. Minority interests
in the Operating Partnership can elect to receive the same consideration per
Unit or an equity interest in the acquiring entity.

                                   (UNAUDITED)

        The Merger Agreement is subject to the vote of the Company's common
stockholders and minority interests. In October 1999, the Company filed a
Definitive Proxy Statement with the Securities and Exchange Commission and
mailed proxy materials to stockholders of records as of October 15, 1999. On
November 17, 1999, the Company will hold a special meeting of stockholder to
vote on the Merger. The Merger Agreement is also subject to certain other
conditions, including the receipt of consents from certain major franchisors of
Sunstone's hotels and the closing of SHP's financing. SHP has received a
commitment for debt financing for the transaction, which is expected to close
during the fourth quarter of 1999.

        As required by the Merger Agreement, the Company will not pay a
distribution to stockholders or minority interests at any time prior to the
closing of the Merger. In conjunction with the Merger, the Company has incurred
and expensed $2.6 million in costs primarily for legal and accounting services
through September 30, 1999. Significant additional transaction costs will be
incurred by the Company if the Merger is consummated. Such significant
additional transaction costs have not been accrued in the accompanying financial
statements of the Company.

3. INVESTMENTS IN HOTEL PROPERTIES

        On July 15, 1999, the Company opened the newly built Courtyard by
Marriott in Lynnwood, Washington, located approximately 15 miles north of
downtown Seattle. The 164-room hotel includes a limited number of suites, as
well as, a restaurant, lobby lounge, pool, fitness room, business center and
approximately 1,500 square feet of meeting space. The hotel was developed by the
Company for a cost of approximately $10.0 million and was financed in part with
proceeds from a $7.7 million promissory note and Building Loan Agreement, both
dated June 28, 1999. This financing is secured by a first deed of trust and
requires monthly interest only payments at either the Prime Rate plus .25% or
LIBOR plus 2.5% per year, but not less than 7% per year and matures June 28,
2000. The Company has the option to extend the maturity date for up to one year.
As of September 30, 1999, $7.5 million was disbursed to the Company under such
promissory note and Building Loan Agreement.

        During the third quarter of 1999, the Company also completed, or was in
the process of completing, substantial renovations at seven of the hotel
properties, and in connection with such renovations, the Company incurred costs
of approximately $6.8 million.

4. REVOLVING LINE OF CREDIT

        At September 30, 1999, the Company had $300.1 million outstanding under
its Credit Facility. Borrowing base and loan-to-value limits, as well as other
financial performance covenants restrict the availability of borrowings under
the Credit Facility and, as of September 30, 1999, the Company could not borrow
any additional amounts. The Company's total liabilities as defined under the
terms of the Credit Facility are restricted by a leverage covenant ("Leverage
Covenant") which allows the Company to borrow funds when the lesser of (i) 50%
of the cost basis of the hotels or (ii) 50% of the cost basis of hotels owned
for no more than six full fiscal quarters plus a valuation based on the net
operating income ("NOI") for hotels owned longer than six fiscal quarters
exceeds the Company's total liabilities. Effective July 1, 1999, the eleven
remaining hotels that were acquired in connection with the acquisition of Kahler
Realty Corporation in October of 1997 (the "Kahler Hotels") were required to be
valued based on their respective NOI. As a result of such change, the Company
was not in compliance with the Leverage Covenant.

        On September 22, 1999, the Credit Facility was amended providing the
Company relief with respect to the Leverage Covenant. This amendment allows the
Kahler Hotels to be valued at their cost basis for an additional two quarters,
for a total of eight quarters. In exchange for such modification, the lenders
required a modification fee of $1.0 million, an increase in the borrowing rate
to LIBOR plus 2.75%, effective July 1, 1999, limitations on expenditures for new
acquisitions and renovations and maintenance of minimum liquidity. Additionally,
in the event the Merger does not close,

                                   (UNAUDITED)

4. REVOLVING LINE OF CREDIT (continued)

the lenders will require the Company to secure the Credit Facility with the
hotel properties and pay additional fees and further increase the borrowing
rate.

        The Credit Facility term expires on July 1, 2000. The Company requested
a one-year extension of the term to July 1, 2001 which the lenders have denied.
As a result, the Company is evaluating possible means of meeting near-term debt
service requirements and improving liquidity through refinancing existing
indebtedness, issuing additional equity securities and divesting certain hotel
assets. The Company also has modified its capital expenditures and renovation
programs. As previously discussed, the Company will not pay a distribution to
stockholders or minority interests at any time prior to the closing of the
Merger (Note 2). However, the Company anticipates that the distributions already
made during 1999 are sufficient to satisfy the federal income tax requirements
with respect to distributions in order for the Company to continue to qualify as
a REIT.

        No assurances can be made regarding the availability or terms of
additional sources of capital for the Company in the future and no assurances
can be given regarding the Company's ability to successfully refinance the
maturity of existing indebtedness, including, without limitation, the Credit
Facility. If the Merger does not close and the Company is unable to secure
additional sources of financing in the future, or is unable to successfully
refinance existing indebtedness, no assurance can be made that the Company will
be able to meet its financial obligations as they come due without substantial
disposition of assets outside the ordinary course of business, restructuring of
debt or revisions of the Company's operations. Additionally, no assurances can
be given that the lack of future financing sources would not have a material
adverse effect on the Company's financial condition and results of operations.

        The computation of diluted earnings per share does not assume the
conversion of the 7.9% Class A Convertible Preferred Stock because their
inclusion would have been anti-dilutive. Additionally, the computation of
diluted earnings per share does not assume the conversion of the Operating
Partnership units because such conversion would not have any impact on diluted
earnings per share.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)


6. COMMITMENTS AND CONTINGENCIES

        Eight substantially similar purported class actions have been filed
concerning the Merger (Note 2). Five of these actions were filed in Maryland
state court and the remaining three were filed in California state court. By
agreement of the parties, the five Maryland state court actions have been stayed
pending resolution of the three parallel actions pending in California state
court. The parties have agreed to consolidate the California actions under the
first case filed in California for all purposes, and a proposed consolidation is
currently being negotiated among the parties. The plaintiffs therein have
indicated that they intend to file a consolidated amended complaint shortly in
the superior Court of the State of California, County of Orange.

        Each of the actions is brought on behalf of a purported class of all our
stockholders other than the named defendants. The complaints, each of which was
filed prior to execution of the Merger Agreement, allege that certain members of
our Board, in conjunction with SHP Acquisition, have breached their fiduciary
duties by negotiating a proposed acquisition of Sunstone for an unfair price. In
addition to certain members of the Board of Directors, the complaints purport to
allege claims against SHP Acquisition, Westbrook Fund I, Westbrook Co-Invest I
and Lessee. Each of the complaints purports to seek injunctive relief and
monetary damages. At the November 5, 1999 case evaluation conference in the
three consolidated California cases, the lead plaintiffs' attorney advised the
Court that they believed the price was fair and were not disputing the
transaction. Plantiffs' attorneys informed the Court that the only remaining
issue to be addressed is the attorney's fees, if any, to be paid to the
plaintiffs' counsel.

        Management is unable to determine whether these lawsuits will have a
material adverse effect on the Company's financial position or results of
operations. The Company intends to defend the lawsuits vigorously. No amounts
related to these lawsuits or contingent amounts related to the Merger have been
accrued in the accompanying financial statements.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)


1. ORGANIZATION AND BASIS OF PRESENTATION

        Sunstone Hotel Properties, Inc. (the "Lessee") was incorporated in
Colorado in October 1994 and commenced operations effective with the completion
of an initial public stock offering by Sunstone Hotel Investors, Inc. (the
"Lessor") on August 15, 1995. The Lessee leases hotel properties, which are
primarily located in the western United States, from the Lessor pursuant to
long-term leases (the "Percentage Leases"). The Lessee operates 100% of the
hotel properties owned by the Lessor. The Lessee is owned by Robert A. Alter,
Chairman and President of the Lessor (80%), and Charles L. Biederman, Director
and Executive Vice President of the Lessor (20%). At September 30, 1999, the
Lessee leased 59 hotel properties from the Lessor.

Basis of Presentation:

        The consolidated financial statements include the accounts of the Lessee
and its subsidiaries. All significant intercompany transactions and balances
have been eliminated.

        The interim consolidated financial statements of the Lessee have been
prepared without audit in accordance with generally accepted accounting
principles for interim information and with the instructions for Form 10-Q and
Article 10 of Regulation S-X. Accordingly, they do not include all of the
information and footnotes required by generally accepted accounting principles
for complete financial statements. The Lessee believes that the disclosures are
adequate to make the information presented not misleading when read in
conjunction with the Lessee's audited consolidated financial statements included
in the Lessor's Annual Report on Form 10-K for the year ended December 31, 1998
and Quarterly Reports on Form 10-Q for prior quarters of 1999. The financial
information presented herein reflects all adjustments, consisting only of normal
recurring accruals, which are, in the opinion of management, necessary for a
fair presentation of the results for the interim periods presented. The results
for the three and nine months ended September 30, 1999 are not necessarily
indicative of the results to be expected for the year ended December 31, 1999.

Seasonality:

        The hotel industry is seasonal in nature. Seasonal variations in hotel
occupancy may cause quarterly fluctuations in the Lessee's revenues.

Use of Estimates:

        The preparation of 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 at the
date of the financial statements and the reported amounts of revenues and
expenses during the reporting periods. Significant estimates include estimates
related to claims, legal actions and other similar contingencies (see Note 5)
and actual results could differ materially from those estimates in the near
term.

Reclassifications:

        Certain prior period balances have been reclassified to conform with the
current period presentation.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)


2. STOCKHOLDERS' DEFICIT

        During the three and nine months ended September 30, 1999, the Lessee
had net losses of $2.4 million and $391,000, respectively. The Lessee has
incurred significant losses from its inception in 1995. At September 30, 1999,
the Lessee's stockholders' deficit amounted to $10.9 million. At September 30,
1999, the Lessee's rent payable to the Lessor amounted to $13.8 million. Also at
September 30, 1999, the Lessee's current liabilities exceeded its current assets
by $10.2 million. The ability of the Lessee to fund its daily operations and
continue to remain current on its substantial rent obligation to the Lessor is a
result of the original terms under the Percentage Leases, for the payment of
rent to the Lessor, which allow monthly base rent to be paid in arrears and
monthly percentage rent to be paid within 45 days after the respective month
end.

3. PERCENTAGE LEASE AGREEMENTS

        At September 30, 1999, all rent payments due the Lessor are current.
Under the terms of the Percentage Leases, base rent is payable to the Lessor in
arrears and percentage rent is payable 45 days after the end of each respective
month. As such and as of September 30, 1999, the $13.8 million due the Lessor
consists of percentage rent for the months of August and September 1999 and base
rent for the month of September 1999.

        Certain Percentage Leases, as amended, allow for the abatement of base
rent related to rooms taken out of service during major renovations. The Lessor
abated $0 and $391,000 of base rent during the three months and nine months
ended September 30, 1999, respectively. No rent was abated during the three and
nine month periods ended September 30, 1998.

4. CERTAIN TRANSACTIONS WITH RELATED PARTIES

        Sunstone Hotel Management, Inc. (the "Management Company"), a company
wholly owned by Robert A. Alter, Chairman of the Lessee, provides management and
accounting services to the Lessee pursuant to the terms of a management
agreement. The agreement has a one year term and is automatically renewed.
Management fees are computed on an individual hotel basis and range from 1% to
2% of gross revenues. Accounting fees are computed as a fixed amount per room on
an individual hotel basis and range from $8.50 to $11.50 per room per month.

        During the three months ended September 30, 1999, the Management Company
agreed to abate management fees for the quarter ended September 30, 1999 which
amounted to $1.2 million and to refund to the Lessee management fees totaling
$900,000 that were already paid by the Lessee. The Management Company also
agreed to abate and refund management fees totaling $1.1 million that were
incurred and paid related to the three months ended June 30, 1999. Accordingly
at September 30, 1999, the Lessee has recorded in due from affiliates $2.0
million in management fees that are to be refunded by the Management Company.
After this abatement of management fees, the net management fees expense for the
nine months ended September 30, 1999 totaled $1.1 million. During the three and
nine months ended September 30, 1998, $1.2 million and $2.3 million,
respectively, in management fees were abated by the Management Company.

        During the three and nine months ended September 30, 1999, $326,000 and
$948,000 in accounting fees were incurred, respectively, and during the three
and nine months ended September 30, 1998, $329,000 and $937,000 in accounting
fees were incurred, respectively.

        Upon the execution of each Percentage Lease, the Lessor assigns certain
hotel operating assets and liabilities to the Lessee at the Lessor's net book
value. The Lessee records all such hotel operating assets and liabilities at the
Lessor's cost with a corresponding net amount payable to or receivable from the
Lessor, depending on whether net assets or liabilities were assigned. The Lessor
also reimburses the Lessee for costs it incurs related to the Lessor's
renovation of hotels.

4. CERTAIN TRANSACTIONS WITH RELATED PARTIES (continued)

        Amounts due from affiliates includes (i) abated management fees to be
refunded by the Management Company; (ii) reimbursements due from the Management
Company for certain expenses paid by the Lessee on behalf of the Management
Company; (iii) certain salaries and other expenses incurred by the Lessee and
allocated to the Management Company; and (iv) reimbursements from the Lessor
reduced by amounts due to the Lessor for net hotel operating assets assigned by
the Lessor to the Lessee upon the execution of each Percentage Lease.
Reimbursements of expenses from the Management Company, which are recorded as a
reduction of the related general and administrative expenses, totaled $298,000
and $586,000, respectively, during the three and nine months ended September 30,
1999.

        At September 30, 1999, the Lessee had a $1.5 million line of credit with
its primary stockholder. The line of credit bears interest at the prime rate
plus 0.25%, is unsecured and has a maturity date of December 29, 1999. The line
is to be used exclusively for general short-term working capital needs. In
January 1999, an additional $800,000 was drawn on the stockholder line of credit
by the Lessee for working capital needs. In February 1999, the Lessee paid down
the line of credit by $650,000, plus related unpaid accrued interest. In June
1999, an additional $650,000 was drawn and $800,000 was paid down on the
stockholder line of credit. Interest incurred on the line of credit during the
three months and nine months ended September 30, 1999 totaled $5,000 and
$36,000, respectively.

        On February 15, 1999, the Lessee began leasing office space from the
Lessor when it moved its corporate facilities into a building owned by the
Lessor.

5. COMMITMENTS AND CONTINGENCIES

        On April 5, 1999, the Lessor received a merger offer from SHP
Acquisition, LLC ("SHP"), formed by Robert A. Alter, certain management
personnel of the Lessee and Westbrook Funds III. Westbrook Partners LLC is a New
York based real estate opportunity fund, an affiliate of the Lessee and a 9.6%
stockholder in the Lessor, whose managing principal, Paul Kazilionis, is a
director of the Lessor.

        Upon receiving the SHP merger offer, the Lessor formed the Special
Committee of the Board of Directors, comprised of all the independent members of
its Board of Directors, to study the proposal and consider the Lessor's
alternatives. The Special Committee was advised by Goldman, Sachs & Co. and
Altheimer & Gray.

        Upon the recommendation of the Special Committee of the Board of
Directors of the Lessor and the approval of the Board of Directors, the Lessor
entered into a merger agreement (the "Merger Agreement" or the "Merger") as of
July 12, 1999 with SHP, an affiliate of Westbrook Partners LLC and certain
members of the Lessor's senior management. Under the terms of the Merger
Agreement each share of common stock of the Lessor will be exchanged for cash,
as specified in the Merger Agreement.

        The Merger Agreement is subject to the vote of the Lessor's common
stockholders and minority interests, as well as certain other conditions,
including the receipt of consents from certain major franchisors of Lessor's
hotels and the closing of SHP's financing. On November 17, 1999, the Lessor will
hold a special meeting of its stockholders to vote on the Merger. SHP has
received a commitment for debt financing for the transaction, which is expected
to close during the fourth quarter of 1999.

        The Merger Agreement provides for a breakup fee and certain expenses to
be paid to SHP in the event that the Lessor wishes to accept a superior
proposal. Under such circumstances, the Lessor has the right to purchase all the
shares of the Lessee and Management Company, for a total amount of $30.0 million
in cash.

5. COMMITMENTS AND CONTINGENCIES (continued)

        In connection with the Merger, eight lawsuits have been filed naming the
Lessor, certain directors and officers of the Lessor and other parties including
the Lessee and its shareholders as defendants. The factual basis alleged to
underlie all eight lawsuits are essentially identical. Substantively, they
assert that Robert A. Alter, Charles L. Biederman and Paul Kazilionis, in
conjunction with Westbrook Partners, LLC (and other purported Westbrook
affiliated entities), SHP Acquisition and the Lessee, have offered an unfair
buyout price for the outstanding shares of the Lessor. Plaintiffs in each of
these lawsuits purport to seek both injunctive relief and damages on behalf of
the purported class based upon these allegations. Management is unable to
determine whether these lawsuits will have a material adverse effect on the
Lessee's financial position or results of operations. The Lessee intends to
defend the actions vigorously. No amounts related to these lawsuits or the
proposed Merger have been accrued in the accompanying financial statements.

        The Lessee is involved from time to time in various claims and legal
actions in the ordinary course of business. Management does not believe that the
resolution of such matters will have a material adverse effect on the Lessee's
financial position or results of operations when resolved.

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

Forward-Looking Statements

        When used throughout this report, the words "believes", "anticipates"
and "expects" and similar expressions are intended to identify forward-looking
statements. Such statements are subject to the many risks and uncertainties
which affect the Company's business, and actual results could differ materially
from those projected and forecasted. These uncertainties, which include
competition within the lodging industry, the balance between supply and demand
for hotel rooms, the Company's continued ability to execute acquisitions and
renovations, the effect of economic conditions, the availability of capital to
finance planned growth, the Year 2000 Issue, and the liquidity of the Lessee,
are described but are not limited to those disclosed in this report. These and
other factors which could cause actual results to differ materially from those
in the forward-looking statements are discussed under the heading "Risk
Factors". Given these uncertainties, readers are cautioned not to place undue
reliance on such statements. The Company also undertakes no obligation to
publicly release the result of any revisions to these forward-looking statements
that may be made to reflect any future events or circumstances. The following
discussion should be read in conjunction with the financial statements included
elsewhere in this report, as well as the information presented in the Company's
Annual Report on Form 10-K for the year ended December 31, 1998 and Quarterly
Reports on Form 10-Q for prior quarters of 1999.

GENERAL

        Sunstone Hotel Investors, Inc. (the "Company" or "Sunstone") is a
self-administered, equity real estate investment trust ("REIT") that through its
94.8% ownership interest in Sunstone Hotel Investors, LP (the "Operating
Partnership"), owns and leases luxury, upscale and mid-price hotels located
primarily in the Pacific and Mountain regions of the western United States. The
hotels operate primarily under national franchises that are among the most
respected and widely recognized in the lodging industry, including brands
affiliated with Marriott International, Inc., Bass Hotels and Resorts, Hilton
Hotels Corporation and Promus Hotel Corporation. As of November 10, 1999, the
Company's portfolio consisted of 59 hotels with a total of 10,525 rooms. The
majority of the Company's hotel portfolio consists of luxury, upscale and
mid-price full-service hotels and upscale extended-stay properties
(approximately 78.0%) with the remainder of the Company's portfolio consisting
of mid-price limited service properties.

ACQUISITION OF SUNSTONE

        On April 5, 1999, the Company received a merger offer from SHP
Acquisition, LLC ("SHP"), certain management personnel of the Lessee and
Westbrook Funds III. The Lessee leases and operates all of the Company's hotels
and is owned by Robert A. Alter, Chairman and Chief Executive Officer of the
Company and Charles L. Biederman, Vice Chairman and Executive Vice President of
the Company. Westbrook Partners LLC is a New York based real estate opportunity
fund, which is a 9.6% stockholder in the Company, whose managing principal, Paul
Kazilionis, is a director of the Company. The original offer to purchase was for
all the common stock of the Company at $9.50 to $10.00 in cash per share.

        Upon receiving the SHP merger offer, the Company formed the Special
Committee of the Board of Directors, comprised of all the independent members of
the Board of Directors, to study the proposal and consider the Company's
alternatives. The Special Committee was advised by Goldman, Sachs & Co. and
Altheimer & Gray.

        Upon the recommendation of the Special Committee of the Board of
Directors of the Company and the approval of the Board of Directors, Sunstone
entered into a merger agreement (the "Merger Agreement" or the "Merger") as of
July 12, 1999 with SHP, an affiliate of Westbrook Partners LLC and certain
members of Sunstone's senior management. Under the terms of the Merger Agreement
each share of common stock of the Company will be exchanged for $10.35 in cash,
subject to adjustments which management currently anticipates will increase the
merger consideration to approximately $10.39 per share. The adjustments provide
that common stockholders will be paid a proportionate share of $2.5 million, or
approximately $0.06 per share. The Merger Agreement also provides for a possible
decrease in the event certain transaction expenses, consent payments or other
payments exceed amounts specified in the Merger Agreement. Management currently
anticipates that these adjustments will result in a decrease of approximately
$0.02 per share. The net result of all the adjustments is currently anticipated
to increase the merger consideration by approximately $0.04 per


                                       19


<PAGE>   20

share to approximately $10.39 per share. The actual amount of the adjustments
will not be determined until shortly prior to the closing of the Merger.
Minority interests in the Operating Partnership can elect to receive the same
consideration per Unit or an equity interest in the acquiring entity.

        The Merger Agreement is subject to the vote of the Company's common
stockholders and minority interests. In October 1999, the Company filed a
Definitive Proxy Statement with the Securities and Exchange Commission and
mailed proxy materials to stockholders of record as of October 15, 1999. On
November 17, 1999, the Company will hold a special meeting of stockholders to
vote on the Merger. The Merger Agreement is also subject to certain other
conditions, including the receipt of consents from certain major franchisors of
Sunstone's hotels and the closing of SHP's financing. SHP has received a
commitment for debt financing for the transaction, which is expected to close
during the fourth quarter of 1999.

        As required by the Merger Agreement, the Company will not pay a
distribution to stockholders or minority interests at any time prior to the
closing of the Merger.

RESULTS OF OPERATIONS

Comparison of the Three Months Ended September 30, 1999 to 1998 and Nine Months
Ended September 30, 1999 to 1998

        Revenues increased to $29.3 million for the three months ended September
30, 1999 from $29.0 million for the third quarter of 1998. For the nine months
ended September 30, 1999, revenues increased to $79.6 million from $77.6 million
for the corresponding period of 1998. The increase in revenues is primarily
attributable to an increased inventory of renovated rooms available for
occupancy during the three and nine months ended September 30, 1999 in
comparison to the corresponding periods of 1998. The revenue increases achieved
due to the completion of renovation activities were partially offset by the
disposition of certain non-core hotels during 1998 and the first quarter of
1999. The Company owned fewer hotels during the three and nine months ended
September 30, 1999 in comparison to the corresponding periods of 1998. Revenue
per available room ("REVPAR") increases for continuously owned hotels also
contributed to the revenue increases.

        On a same-unit-sales basis for the entire hotel portfolio, REVPAR
increased 1.1% to $61.91 for the third quarter of 1999 from $61.25 for the third
quarter of 1998. The 1.1% growth in REVPAR was driven by an increase in the
average daily rate ("ADR") to $85.40 from $84.52.

        REVPAR for the non-renovation hotels increased by 2.5%. Non-renovation
hotels include 48 of the Company's 59 hotels owned as of September 30, 1999
which were not under renovation in either the third quarter of 1998 or 1999. The
2.5% growth in REVPAR was driven by an increase in the ADR to $87.32 from $87.24
and an increase in occupancy to 75.6% from 73.9%.

        During the third quarter of 1999, certain of the Company's hotel markets
were negatively impacted by new supply or decreased demand. Specifically, the
Seattle and Pueblo hotel markets, as well as Arizona had significant new supply
come on-line. Also, the Seattle hotel market continued to experience less than
anticipated demand during the third quarter. On-going supply/demand imbalances
in these markets may continue to negatively impact certain of the Company's
hotels in the near-term.

(1) Excludes the Hampton Inn located in Arcadia, California which was sold
    during the first quarter of 1999.

(2) Includes seven hotels undergoing renovation in the third quarter of 1999 and
    four hotels undergoing renovation in the third quarter of 1998.

        Real estate related depreciation and amortization increased $1.6 million
and $5.0 million for the three and nine months ended September 30, 1999,
respectively, over the corresponding periods of 1998. These increases are
consistent with the net increase in investments in hotel and other real estate
properties. Also contributing to the increases is depreciation of renovations
completed at the hotel properties during 1998 and the first half of 1999.

        Interest expense and amortization of financing costs increased $2.5
million to $9.4 million for the three months ended September 30, 1999 from $6.9
million for the corresponding quarter of 1998. For the nine months ended
September 30, 1999, interest expense and amortization of financing costs
increased $6.0 million to $23.1 million from $17.1 million for the corresponding
period of 1998. These increases are attributable to higher average borrowings
outstanding, increased borrowing rate, effective July 1, 1999, due to the
amendment to the Credit Facility, and reduced interest capitalized related to
hotels undergoing major renovations for the three and nine months ended
September 30, 1999 in comparison to the corresponding periods of 1998.

        General and administrative expenses decreased to $725,000 for the three
months ended September 30, 1999 from $1.6 million for the corresponding quarter
of 1998. For the nine months ended September 30, 1999, general and
administrative expenses decreased to $3.6 million from $4.0 million for the
corresponding period of 1998. The decreases are primarily attributable to due
diligence costs incurred in the third quarter of 1998 and not incurred in the
third quarter of 1999. During the third quarter of 1998, the Company incurred
and expensed $553,000 of costs related to the termination of a significant hotel
portfolio acquisition that was under consideration.

                                       21

<PAGE>   22

        As previously discussed, the Company has entered into a Merger Agreement
to be acquired by SHP. In conjunction with this transaction, the Company has
incurred and expensed $337,000 and $2.6 million for the three and nine months
ended September 30, 1999, respectively. These costs were primarily for legal and
accounting services.

        During the first quarter of 1999, the Company disposed of the 129-room
Hampton Inn located in Arcadia, California, for $8.5 million and recognized a
$490,000 gain.

        As a result of the above factors, income available to common
stockholders increased to $4.2 million for the three months ended September 30,
1999 from $4.1 million for the third quarter of 1998, while diluted earnings per
share remained at $0.11 per share. For the nine months ended September 30, 1999,
income available to common stockholders decreased to $8.6 million from $16.0
million for the third quarter of 1998, while diluted earnings per share
decreased to $0.23 from $0.43 per share.

Seasonality and Regional Focus

        The Company currently focuses its acquisition efforts principally on the
Pacific and Mountain regions which collectively comprise the western United
States. The geographic distribution of the hotels, which are located in eight
states as of November 10, 1999, reflects the Company's belief that a certain
amount of geographic distribution helps to insulate the Company's hotel
portfolio from local market fluctuations and off-peak seasonal operations that
are typical for the hotel industry. The Company has also sought to increase its
geographic distribution by focusing on major metropolitan areas.

LIQUIDITY AND CAPITAL RESOURCES

        Distributions. As previously discussed, the Company has entered into a
Merger Agreement to be acquired by SHP. As required by the Merger Agreement, the
Company will not pay a distribution to stockholders or minority interests at any
time prior to the closing of the Merger. Accordingly, the Company did not
declare a dividend for the third quarter of 1999.

        Cash Flow Provided by Operating Activities. The Company's principal
source of cash to fund operating expenses and distributions is cash flow
provided by rent paid by the Lessee. For the nine months ended September 30,
1999, the Lessee failed to achieve the hotel revenues contemplated in the budget
and subsequent forecasts provided to the Company. As a result, rent paid by the
Lessee was less than anticipated. The Lessee's obligations under the Percentage
Leases are largely unsecured and the Lessee's ability to make rent payments to
the Company under the terms of the Percentage Leases are substantially dependent
on the Lessee's ability to generate sufficient cash flow from the operations of
the hotels. (See discussion of the Lessee's stockholders' deficit in the
following section, "The Lessee").

        The Company is required under the Percentage Leases to make available to
the Lessee for repair, replacement and refurbishment of furniture, fixtures and
equipment an amount equal to 4% of room revenue per quarter on a cumulative
basis. These funds are intended to maintain the hotels in a competitive
condition. In the event the Merger does not close, the Company anticipates that
cash flow from operations for the fourth quarter of 1999 will be insufficient to
fund capital expenditures required under the Percentage Leases, operating
expenses and distributions at the level prior to entering into the Merger
Agreement. Accordingly, it may be necessary for the Company to defer or reduce
the scope of capital expenditures, sell hotel properties or reduce distributions
in the event the Merger does not close.

        Cash and cash equivalents as of September 30, 1999 were $6.0 million, as
compared to $859,000 at December 31, 1998. Net cash provided by operating
activities for the nine months ended September 30, 1999 was $40.4 million.


                                       22

<PAGE>   23

        Cash Flows from Investing and Financing Activities. During the nine
months ended September 30, 1999, the Company invested $78.5 million in hotel
properties and $3.9 million in other real estate investments. These investments
were primarily funded with borrowings from the Company's $350.0 million
unsecured revolving line of credit facility (the "Credit Facility") from its
lenders (led by Bank One of Arizona, N.A., as the agent bank) and promissory
notes secured by certain hotel properties.

        At September 30, 1999, the Company had $300.1 million outstanding under
its Credit Facility. Borrowing base and loan-to-value limits, as well as other
financial performance covenants restrict the availability of borrowings under
the Credit Facility and, as of November 10, 1999, the Company cannot borrow any
additional amounts. The Company's total liabilities as defined under the terms
of the Credit Facility are restricted by a leverage covenant ("Leverage
Covenant") which allows the Company to borrow funds when the lesser of (i) 50%
of the cost basis of the hotels or (ii) 50% of the cost basis of hotels owned
for no more than six full fiscal quarters plus a valuation based on the net
operating income ("NOI") for hotels owned longer than six fiscal quarters
exceeds the Company's total liabilities. Effective July 1, 1999, the eleven
remaining hotels that were acquired in connection with the acquisition of Kahler
Realty Corporation in October of 1997 (the "Kahler Hotels") were required to be
valued based on their respective NOI. As a result of such change, the Company
was not in compliance with the Leverage Covenant.

        On September 22, 1999, the Credit Facility was amended providing the
Company relief with respect to the Leverage Covenant. The amendment allows the
Kahler Hotels to be valued at their cost basis for an additional two quarters,
for a total of eight quarters. In exchange for such modification, the lenders
required a modification fee of $1.0 million, an increase in the borrowing rate
to LIBOR plus 2.75%, effective July 1, 1999, limitations on expenditures for new
acquisitions and renovations and maintenance of minimum liquidity. Additionally,
in the event the Merger does not close, the lenders will require the Company to
secure the Credit Facility with the hotel properties and pay additional fees and
further increase the borrowing rate.

        The Credit Facility term expires on July 1, 2000. The Company requested
a one-year extension of the term to July 1, 2001 which the lenders have denied.
As a result, the Company is evaluating possible means of meeting near-term debt
service requirements and improving liquidity through refinancing existing
indebtedness, issuing additional equity securities and divesting certain hotel
assets. The Company also has modified its capital expenditures and renovation
programs. As previously discussed, the Company will not pay a distribution to
stockholders or minority interests at any time prior to the closing of the
Merger. However, the Company anticipates that the distributions already made
during 1999 are sufficient to satisfy the federal income tax requirements with
respect to distributions in order for the Company to continue to qualify as a
REIT.

        No assurances can be made regarding the availability or terms of
additional sources of capital for the Company in the future and no assurances
can be given regarding the Company's ability to successfully refinance the
maturity of existing indebtedness, including, without limitation, the Credit
Facility. If the Merger does not close and the Company is unable to secure
additional sources of financing in the future, or is unable to successfully
refinance existing indebtedness, no assurance can be made that the Company will
be able to meet its financial obligations as they come due without substantial
disposition of assets outside the ordinary course of business, restructuring of
debt or revisions of the Company's operations. Additionally, no assurances can
be given that the lack of future financing sources would not have a material
adverse effect on the Company's financial condition and results of operations.

        During the nine months ended September 30, 1999, the Company invested
approximately $38.6 million renovating hotels. During this period there were
twelve hotels that were undergoing significant renovation activities. As
previously discussed and in an effort to improve the Company's near-term
liquidity, the Company has modified its capital expenditure and renovation
programs such that future investments in hotels will be made to prevent or
address guest satisfaction issues and to maintain the hotels in a competitive
condition. The Company estimates it will invest an additional $10.6 million
during the fourth quarter of 1999 to complete the renovation of those hotels
currently under renovation and to maintain the competitive condition of the
hotel portfolio.

        The Company has selectively developed luxury and upscale hotels in
markets where management believes room demand and other competitive factors
justify new construction. During the second quarter of 1999, the Company
completed the acquisition of two newly built hotel properties, the 121-room
Residence Inn by Marriott in San Diego and the 154-room Hilton Garden Inn in
Sacramento, for a total of $28.0 million. Both hotels were acquired under the
terms


                                       23

<PAGE>   24

of definitive purchase agreements which were entered into during the fourth
quarter of 1997 with third party developers. The acquisition of the two hotels
was financed, in part, with proceeds from a $20.8 million promissory note dated
May 27, 1999 that requires monthly interest only payments at either the Prime
Rate plus .50% or LIBOR plus 2.0%, matures May 27, 2001 and is secured by the
two hotel properties.

        On July 15, 1999, the Company opened the newly built Courtyard by
Marriott in Lynwood, Washington, located approximately 15 miles north of
downtown Seattle. The 164-room hotel includes a limited number of suites, as
well as a restaurant, lobby lounge, pool, fitness room, business center and
approximately 1,500 square feet of meeting space. The hotel was developed by the
Company for a cost of $10.0 million and was financed in part with proceeds from
a $7.7 million promissory note and Building Loan Agreement, both dated June 28,
1999. This financing is secured by a first deed of trust and requires monthly
interest only payments at either the Prime Rate plus .25% or LIBOR plus 2.5% per
year, but not less than 7% per year and matures June 28, 2000. The Company has
the option to extend the maturity date for up to one year. As of September 30
1999, approximately $7.5 million was disbursed to the Company under such
building Loan Agreement.

        On May 11, 1999, the Company repaid a $6.1 million promissory note with
proceeds from a $16.1 million promissory note dated May 7, 1999 that requires
monthly interest only payments at LIBOR plus 2.25%, and is secured by certain
hotel properties. In the event the Merger does not close, the Company will seek
to extend or refinance this note, which matured on October 30, 1999.
Additionally, on May 17, 1999, the Company issued 277,513 shares of its common
stock under the Company's Dividend Reinvestment and Stock Purchase Plan (the
"Plan"). The Plan provides for the issuance of common stock at a price based on
the twelve day trading period subsequent to acceptance and subject to certain
thresholds and discounts as set by the Company. The issuance price of the shares
sold was $9.08 per share, resulting in proceeds of approximately $2.5 million.

Funds From Operations ("FFO")

        Management believes that funds from operations ("FFO") is a useful
measure of financial performance of an equity REIT, such as the Company. FFO (as
defined in the footnote below) for the three and nine months ended September 30,
1999 decreased by 8.9% and 9.1%, respectively, over the corresponding periods of
1998.

--------------------
Management and industry analysts generally consider Funds From Operations to be
an appropriate measure of the performance of an equity REIT. The White Paper on
Funds From Operations (the "FFO White Paper") approved by the Board of Governors
of the National Association of Real Estate Investment Trusts ("NAREIT") defines
Funds From Operations as net income or loss (computed in accordance with GAAP),
excluding gains or losses from debt restructuring and sales of property, plus
real estate related depreciation and amortization, and after adjustments for
unconsolidated partnerships and joint ventures. The Company computes Funds From
Operations in accordance with standards established by NAREIT, adjusted for
minority interest and nonrecurring transaction costs, which may not be
comparable to Funds From Operations reported by other REITs that do not define
the term in accordance with the current NAREIT definition or that interpret the
current NAREIT definition differently than the Company. The Company's
computation of FFO does not reflect the revisions made to the FFO White Paper in
October 1999, which are effective beginning January 1, 2000.

Funds From Operations should be considered in conjunction with net income and
cash flows from operating, investing and financing activities as presented in
the Company's consolidated financial statements and notes thereto. Funds From
Operations should not be considered as an alternative to net income (determined
in accordance with GAAP) as an indication of the Company's financial performance
or to cash flow from operating, investing or financing activities (determined in
accordance with GAAP) as a measure of the Company's liquidity, nor is it
indicative of funds available to fund the Company's cash needs, including its
ability to make cash distributions. Funds From Operations may include funds that
may not be available for management's discretionary use due to the requirements
to conserve funds for capital expenditures and property acquisitions and other
commitments.

The Lessee

         For a discussion of the Lessee's revenue operations and a comparison of
the three and nine months ended September 30, 1999 to 1998, see "Results of
Operations" of the Company. Additionally, the Lessee has incurred significant
losses from its inception in 1995. At September 30, 1999, the Lessee's
stockholders' deficit amounted to $10.9 million. At September 30, 1999, the
Lessee's rent payable to the Company amounted to $13.8 million. Also at
September 30, 1999, the Lessee's current liabilities exceeded its current assets
by $10.2 million. The ability of the Lessee to fund its daily operations and
continue to remain current on its substantial rent obligation to the Company is
a result of the original terms under the Percentage Leases, for the payment of
rent to the Company, which allow monthly base rent to be paid in arrears and
monthly percentage rent to be paid within 45 days after the respective month
end.

YEAR 2000 ISSUE

        The term "Year 2000 Issue" is a general term used to describe the
complications that may be caused by existing computer hardware and software that
were designed by the respective manufacturers without consideration of the
upcoming change in the century. Many computer systems recognize calendar years
by the last two digits in the date code field. Beginning in the year 2000, these
date code fields will need to accept four digit entries to distinguish
twenty-first century dates from twentieth century dates. If not corrected,
computer systems may fail or create erroneous results causing disruptions of
operations.

        The Company's in-house computer systems environment is limited to
software and hardware developed by third parties. All of the Company's computer
systems, consisting of financial reporting and accounting systems only, were
installed in the last two years and management believes such systems are Year
2000 compliant. However, the Company's business is heavily dependent upon the
efforts of the Lessee and third parties with whom the Lessee conducts
significant business.

        The Lessee relies on information technology ("IT") systems and other
systems and facilities such as PBX switches, elevators, heating, ventilation and
air conditioning, security, fire and life safety and other environmental systems
("embedded systems") to conduct its business. Both the IT and the embedded
systems are subject to the Year 2000 Issue which, if not remedied in time, could
have an impact on the operations of the Lessee. The Lessee also may be exposed
to risk from third parties with whom the Lessee interacts who fail to adequately
address their own Year 2000 issues. Such third parties include franchisors,
vendors, suppliers and significant customers.

        To mitigate and minimize the number and seriousness of any disruptions
caused by the Year 2000 Issue, the Company and the Lessee have developed and
adopted a Year 2000 Compliance Program (the "Compliance Program") which involves
the following four phases: assessment, which includes development of an action
plan and inventorying of hotel systems, remediation, testing and implementation.
With the assistance of outside consultants, site surveys have been performed and
all hotel systems have been identified and inventoried and include information
such as the manufacturer or vendor who performed the installation or currently
services or maintains each system. The Lessee has completed contacting these
vendors to obtain certification relating to their Year 2000 compliance testing.
In addition, all parties for building systems that service leased premises, or a
facility within leased premises are located and are operated and controlled by
or interact with a software program will be identified and contacted. It should
be noted that due to the complexity of some of the systems, in many cases, the
only way to determine the potential impact of the systems would be to verify the
Year 2000 effect with the particular vendor. The assessment phase was completed
in February 1999.

Status of Progress in Becoming Year 2000 Compliant, Including Timetable for
Completion of Each Remaining Phase - Hotel and Lessee Systems:

        Based on the results of the site assessments, the identified IT and
embedded systems will be replaced or upgraded. The system upgrades will be
prioritized according to their critical importance. Life safety systems and
emergency services will take priority in accordance with the steps laid out in
the Compliance Program. The various vendors associated with any system
replacements or upgrades have been contacted to determine their readiness to
deal with these system enhancements. Performance of certain testing by the
vendors may be required in several cases to ensure Year 2000 compliance. Certain
vendors, manufacturers, service personnel, consultants, contractors, lessees and
lessors will be requested to prepare a letter certifying and warranting that all
systems, utilities and services containing time and date-related coding and
internal programs, shall continue without interruption beyond December 31, 1999.
The implementation will be monitored and managed on a real-time basis to ensure
a smooth upgrade of the systems. Completion of the implementation and testing
phases for all significant systems was achieved in July 1999, and all remediated
systems have been fully tested and evaluated as of November 10, 1999.

Nature and Level of Importance of Third Party Systems and Their Exposure to the
Year 2000:

        The Lessee has completed surveying its vendors and service providers
that are critical to the Lessee's business to determine whether they are Year
2000 compliant, and as of the end of the third quarter of 1999, the Lessee has
determined the extent to which the Lessee will be able to replace those vendors
not in compliance. There may be instances in which the Lessee will have no
alternative but to remain with non-compliant vendors or service providers. The
inability of vendors to complete their Year 2000 resolution process in a timely
fashion could materially impact the Company and the Lessee. The effect of
compliance by vendors is not determinable.

Cost of Addressing Year 2000 Issues:

        The Company estimates that total cost for the Year 2000 compliance
review, evaluation, assessment and remediation efforts should not exceed $1.0
million and will be funded by the Company through its operating cash flows. To
date, the costs incurred to address the Year 2000 issue consist primarily of
services provided by outside consultants for onsite system surveys and the
replacement and upgrade of hardware and software and total $555,000. Of these
costs, $163,000 related to consulting services was expensed by the Company in
the first quarter of 1999, with the balance related to hardware and software
purchases capitalized as of September 30, 1999.

Risks Presented by Year 2000 Issues:

        Management of the Company and the Lessee believe they have an effective
plan in place to resolve the Year 2000 Issue in a timely manner. As noted above,
the Lessee has not yet completed all necessary phases of the Year 2000 program.
In the event that the Lessee does not complete any additional phases, the Lessee
may encounter system failures associated with third-party vendors such as
disruptions in passenger transportation or transportation systems generally,
loss of utility and telecommunications services, the loss or disruption of hotel
reservations made on centralized reservation systems and errors or failures in
financial transactions or payment processing systems such as credit cards. These
disruptions could adversely affect the Company and the Lessee, their businesses
and their financial conditions. The Company and the Lessee cannot predict the
actual effects of the Year 2000 Issue on their businesses, such effects depend
on numerous uncertainties such as whether significant third parties have
properly and timely addressed the Year 2000 Issue, and whether broad-based or
systemic economic failures may occur. Due to the general uncertainty inherent in
the Year 2000 Issue and the Company's and Lessee's dependence on third parties,
Management is unable to determine at this time whether the consequences of Year
2000 failures will have a material impact.

Contingency Plan:

        The Lessee is in the process of developing its contingency plan for the
systems operated and maintained by the Lessee and the hotels. This is necessary
in order to provide for the most likely worst case scenarios regarding Year 2000
compliance. The contingency plan is expected to be completed in 1999.

                          PART II -- OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

        Eight substantially similar purported class actions have been filed
concerning the proposed merger. (See discussion of proposed acquisition in Part
I, Item 2, "Liquidity and Capital Resources.") Five of these actions were filed
in Maryland state court and the remaining three were filed in California state
court. By agreement of the parties, the five Maryland state court actions have
been stayed pending resolution of the three parallel actions pending in
California state court. The parties have agreed to consolidate the California
actions under the first case filed in California for all purposes, and a
proposed consolidation is currently being negotiated among the parties. The
plaintiffs therein have indicated that they intend to file a consolidated
amended complaint shortly in the superior Court of the State of California,
County of Orange.

        The five suits that have been brought in Maryland are: (i) Belloco v.
Sunstone Hotel Investors, Inc. et al., Baltimore County Circuit Court, Case No.
24-C-99-001601, (filed April 7, 1999); (ii) Brenin v. Sunstone Hotel Investors,
Inc. et al., Montgomery County Circuit Court, Case No. 198629-V (filed April 7,
1999); (iii) Rongelap Resettlement Trust Fund v. Sunstone Hotel Investors, inc.
et al., Montgomery County Circuit Court, Case No. 198654-V, filed (April 7,
1999); (iv) Branch v. Alter, et al., Baltimore County Circuit Court, Case No.
03-C-99-003422, (filed April 8, 1999); and (v) Multi v. Sunstone Hotel
Investors, Inc., et al., Circuit Court of Baltimore City, (filed April 21,
1999).

        The three suits that have been brought in California are: (i) Yuan v.
Alter et al., Orange County Superior Court, Case No. CV 807886 (filed April 8,
1999) (per letter from plaintiff's lawyer); (ii) Mittleman v. Sunstone Hotel
Investors, Inc., et al., Orange County Superior Court, Case No. CV 808099
(summons issued April 14, 1999); and (iii) Buie and Smith v. Sunstone Hotel
Investors, Inc., et al., Orange County Superior Court, Case No. 808233 (filed
April 26, 1999).

        Each of the actions is brought on behalf of a purported class of all our
stockholders other than the named defendants. The complaints, each of which was
filed prior to execution of the Merger Agreement, allege that certain members of
our Board, in conjunction with SHP Acquisition, have breached their fiduciary
duties by negotiating a proposed acquisition of Sunstone for an unfair price. In
addition to certain members of the Board of Directors, the complaints purport to
allege claims against SHP Acquisition, Westbrook Fund I, Westbrook Co-Invest I
and Lessee. Each of the complaints purports to seek injunctive relief and
monetary damages. At the November 5, 1999 case evaluation conference in the
three consolidated California cases, the lead plaintiffs' attorney advised the
Court that they believed the price was fair and were not disputing the
transaction. Plantiffs' attorneys informed the Court that the only remaining
issue to be addressed is the attorneys fees, if any, to be paid to the
plaintiffs' counsel. The Company intends to defend the lawsuits vigorously.

ITEM 5. OTHER INFORMATION

                                  RISK FACTORS

LIQUIDITY

        Our hotels generate cash flow in the form of rent we receive from the
Lessee, the entity that leases and operates our hotels. The Lessee's rent is
tied to hotel operating performance and consists of base rent and rent that is a
percentage of certain hotel revenues. In addition, historically we have had
access to cash available from the Credit Facility with a maximum commitment of
$350.0 million with the actual availability based on our assets and financial
performance. We also have been able to raise cash by issuing equity securities
in the public markets. We use these three sources of cash from


                                       28

<PAGE>   29

hotel operations, from borrowings and from sales of stock -- to fund our
acquisition of hotels, renovation of hotels, recurring capital expenditures,
operating expenses and the payment of dividends to our shareholders. Our ability
to access the Credit Facility has been restricted by the performance of our
hotels and the Leverage Covenants under the Credit Facility as described in
Liquidity and Capital Resources. Finally, because of the recent conditions in
the capital markets, it is currently difficult for many companies, especially
REITs, to raise capital by issuing debt or equity securities. No assurances can
be made regarding the availability or terms of additional sources of capital for
the Company in the future. If the Merger does not close and the Company is
unable to secure additional sources of financing in the future or is unable to
successfully refinance existing indebtedness, no assurance can be made that the
Company will be able to meet its financial obligations as they come due without
substantial disposition of assets outside the ordinary course of business,
restructuring of debt or revisions of the Company's and Lessee's operations.
Additionally, no assurances can be given that the lack of future financing
sources would not have a material adverse effect on the Company's financial
condition and results of operations.

TOTAL DEPENDENCE ON THE LESSEE AND PAYMENTS UNDER THE PERCENTAGE LEASES

        Because of our status as a REIT, we are prohibited from operating hotels
and must lease them to the Lessee or other third parties. Our ability to pay
dividends to our shareholders depends on our Lessee's ability to generate
sufficient revenue to pay percentage rent required under the Percentage Leases.
The Lessee was chosen because Messrs. Alter and Biederman, who own the Lessee,
were involved in the management of certain hotels contributed as part of our
initial public offering ("IPO") in 1995.

        The Lessee has incurred significant losses since its inception in 1995.
At September 30, 1999, the Lessee's stockholders' deficit amounted to $10.2
million. At September 30, 1999, the Lessee's rent payable to the Company
amounted to $13.8 million. Also at September 30, 1999, the Lessee's current
liabilities exceeded its current assets by $10.9 million. The ability of the
Lessee to fund its daily operations and continue to remain current on its
substantial rent obligation to the Company is a result of the original terms
under the Percentage Leases, for the payment of rent to the Company, which allow
monthly base rent to be paid in arrears and monthly percentage rent to be paid
within 45 days after the respective month-end. There can be no assurances,
however, that the Lessee will continue to make its rent payments in a timely
fashion.

        According to the Lessee, the losses are due to several factors,
including:

        o   the substantial number of renovations we undertook adversely
            affected occupancy rates and revenues at the hotels;

        o   renovations caused greater revenue losses than expected; and

        o   poorer performance at certain hotels than expected.

        There can be no assurance that the Lessee will generate adequate
operating cash flows to meet its obligations. Other than its cash flow generated
by operating the hotels, the Lessee has no financial resources or other assets
to pay its operating obligations or its rent under the Percentage Leases.
Messrs. Alter and Biederman have pledged a subordinated interest in 481,955
Units to secure the Lessee's obligations under the Percentage Leases. However,
if the Lessee defaults under the Percentage Leases, the value of these Units and
other assets of the Lessee will be insufficient to satisfy our claims against
the Lessee.

RISKS RELATED TO DEVELOPMENT AND RENOVATION OF HOTELS

        Our growth strategy of acquiring hotels needing substantial renovation
or redevelopment affecting the Company's results of operations and financial
condition include the following:

        o   We may continue to incur significant renovation and construction
            cost overruns and time delays due to:

            -  labor shortages;


                                       29


<PAGE>   30

            -  changes in the scope of a project;

            -  requirements imposed by local building inspectors;

            -  discovery of defects in the building once renovation has begun;
               and

            -  compliance with the Americans with Disabilities Act of 1990,
               which may require expensive modifications to existing hotels to
               bring them into compliance.

        o   We may purchase a hotel or contract to acquire a hotel (after a
            third party completes construction) when market conditions are
            favorable but then face deteriorated local demand for hotel rooms
            when the hotel is available for occupancy resulting in revenues that
            are less than projected;

        o   We may complete our renovation after significant delays reducing the
            amount of revenues expected to be received during the delay period;
            and

        o   We may spend more than budgeted for a renovation project reducing
            our anticipated return on the investment.

CONFLICTS OF INTEREST BETWEEN THE COMPANY AND CERTAIN OFFICERS AND DIRECTORS

        The relationship among Mr. Alter and Mr. Biederman, the Lessee, the
Management Company and us creates several inherent conflicts of interest that
may result in decisions being made by our management that are not in the best
interests of our stockholders. The most significant conflicts of interest
include the following:

        o   As owners of SHP Acquisition LLC, Messrs. Alter and Biederman have
            several conflicts of interest arising from the Merger proposed with
            us including the following:

            o   Mr. Alter, our President and Chief Executive Officer and the
                Chairman of our Board of Directors, will serve as chief
                executive officer of SHP Acquisition immediately after
                consummation of the Merger and, through his affiliates, will
                hold significant equity in SHP Acquisition and will be entitled
                to receive a disproportionate amount of the profits from SHP
                Acquisition after certain other members of SHP Acquisition have
                received a specified return on their investment;

            o   Mr. Alter has entered into a five-year employment agreement with
                SHP Acquisition (to serve as its chief executive officer), which
                will provide for, among other things, an annual salary of
                $500,000 and a bonus of up to $920,000;

            o   Mr. Biederman, the Vice Chairman of our Board of Directors, has
                entered into a five-year employment agreement with SHP
                Acquisition, which will provide for, among other things, an
                annual salary of $200,000 and a bonus of up to $80,000, will
                hold equity in SHP Acquisition through his affiliates and will
                be entitled to receive a disproportionate amount of the profits
                from SHP Acquisition after certain other members of SHP
                Acquisition have received a specified return on their
                investment;

            o   In connection with the sale of Lessee and the Management Company
                to SHP Acquisition, which sale will be completed immediately
                prior to the Merger, Messrs. Alter and Biederman (or their
                affiliates) will receive, as the stockholders of the Lessee and
                the Management Company, in addition to the equity in SHP
                Acquisition referred to above, an aggregate amount of $8.45
                million in cash (of which Mr. Alter will receive $3 million),
                and as well as the release of certain personal guarantees and
                indemnities and the termination of certain obligations to us;

        o   As the owners of the Lessee, Mr. Alter and Mr. Biederman will
            benefit from any profits the Lessee may generate from the operation
            of the hotels and retain for itself, even though under the Unit
            Purchase Agreement, Messrs. Alter and Biederman have agreed to
            reinvest the Lessee's profits (net of tax liabilities) in additional
            units or retain the profits as security for future rent payments.


                                       30


<PAGE>   31

        o   As the owner of the Management Company, Mr. Alter is entitled to the
            profits of the Management Company, which receives from the Lessee
            management fees (1% to 2% of gross revenues of the hotels) and
            reimbursements for certain accounting expenses.

        o   The Percentage Leases generally require us to pay a termination fee
            to the Lessee if we elect to sell a hotel and not replace it with a
            Percentage Lease for another hotel. As a result, our decisions about
            which hotels to sell may be influenced by the conflict of interest
            of Messrs. Alter and Biederman who, as owners of the Lessee, would
            benefit from the termination fee.

        o   In connection with our IPO, Messrs. Alter and Biederman contributed
            tax free certain hotels that had a tax basis less than their fair
            market value. Significant taxable gains that would arise if we were
            to sell these hotels would be specifically allocated to Messrs.
            Alter and Biederman. Further, in order to prevent adverse tax
            consequences to Messrs. Alter and Biederman, we must maintain
            mortgage debt at certain minimum levels. Because of these conflicts,
            our decisions concerning whether to sell certain hotels or to incur
            or repay debt will be influenced by the tax consequences for Messrs.
            Alter and Biederman.

        o   We did not negotiate the Percentage Leases on an arm's length basis
            with the Lessee. The base rent, percentage rent and the economic
            terms of each Percentage Lease are determined by us and approved by
            the Lessee based on historical financial data and projected
            operating and financial data for each hotel. See "Total Dependence
            on the Lessee and Payments under the Percentage Leases."

RELIANCE ON MR. ALTER AND OTHER KEY PERSONNEL

        Our success depends in large part upon our ability to attract and retain
highly qualified personnel. Further, because our sole source of operating
revenue is base and percentage rent paid by the Lessee, our success is also
dependent on the Lessee's management's ability to effectively operate the
hotels. Competition for qualified employees for us and the Lessee is extremely
intense and there is no assurance that we or the Lessee can attract and retain
qualified employees. In particular, we substantially rely on the hotel and real
estate knowledge and experience and continuing services of Mr. Robert Alter, our
Chairman, Chief Executive Officer and President. Our inability (or the Lessee's)
to attract and retain qualified employees could negatively affect our ability to
generate revenues and pay distributions to our shareholders.

INVESTMENT CONCENTRATION IN SINGLE INDUSTRY

        Our investment strategy is to focus exclusively on acquiring and owning
hotels. This strategy concentrates all our investment in a single industry and
therefore does not diversify our sources of revenues. As a result, a downturn in
the hotel industry will have a greater impact on our revenues and funds from
operations than if we had a diversified portfolio of properties. In addition,
because we have focused on the western United States and in the luxury, upscale
and mid-price segments of the hotel industry, economic or other conditions that
affect this geographic region or these segments may disproportionately impact
us.

FAILURE TO REALIZE BENEFITS OF RECENT ACQUISITIONS

        We have grown rapidly since our IPO. This growth has required us, and,
to a greater extent, the Lessee to develop scaleable operating systems, develop
construction management procedures and systems and other procedures and systems
to operate our multi-state hotel portfolio. If we, or the Lessee, fail to
effectively integrate the acquired hotels into our operating systems, then we
will not achieve the expected benefits of the acquisition.

        The revenues generated by the hotels we acquire are used to pay the debt
service on the funds we borrow to fund these acquisitions. If the acquired
hotels do not generate sufficient cash flow to fund debt service on the money
borrowed to purchase those hotels, we will be required to service the debt with
cash flows from other hotels which might adversely affect our cash available for
other purposes, including distributions to our shareholders. Further, as
discussed under Liquidity and Capital Resources, the failure of acquired hotels
to generate sufficient net operating income may cause non-compliance with
financial covenants in our Credit Facility.

FAILURE TO MAINTAIN REIT STATUS

        We intend to operate so as to be taxed as a REIT under the Internal
Revenue Code of 1986, as amended. As long as we qualify for taxation as a REIT,
with certain exceptions, we will not be taxed at the corporate level on our
taxable income that is distributed to our shareholders. A REIT is subject to a
number of organizational and operational requirements, including requirements as
to the nature of its income and assets, distribution requirements, diversity of
stock ownership requirements and record-keeping requirements. We intend to
satisfy all of these requirements for treatment as a REIT. It is possible that
we may fail to satisfy one or more of these requirements. Failure to qualify as
a REIT would render us subject to tax on our income at regular corporate rates
and we could not deduct distributions to our shareholders. Unless entitled to
relief under certain Internal Revenue Code provisions, we also would be
disqualified from treatment as a REIT for the four taxable years following the
year during which qualification was lost. Even if we qualify for taxation as a
REIT, we may be subject to certain state and local taxes on our income and
property.

        In order for us to be taxed as a REIT, the Partnership must be
classified as a partnership for federal income tax purposes. If the Partnership
were to be taxable as a corporation, because our ownership interest in the
Partnership constitutes more than 10% of the Partnership's voting securities and
exceeds 5% of the value of our assets, we would cease to qualify as a REIT. The
imposition of corporate income tax on us and the Partnership would substantially
reduce the amount of cash available for distribution to our shareholders.

OWNERSHIP LIMITATION

        In order for us to maintain our qualification as a REIT, not more than
50% in value of our outstanding stock may be owned, directly or indirectly, by
five or fewer individuals (which includes certain entities). Furthermore, if any
shareholder or group of shareholders of the Lessee owns, actually or
constructively, 10% or more of our stock we would likely lose our REIT status.
To protect our REIT qualification, our Articles of Incorporation prohibit direct
or indirect ownership of more than 9.8% of the outstanding shares of our stock
by any person or group. Generally, the capital stock owned by affiliated owners
will be aggregated for purposes of this ownership limitation. Subject to certain
exceptions, any stock subject to a purported transfer that would prevent us from
continuing to qualify as a REIT will be designated as "Shares-in-Trust" and
transferred automatically to a trust effective on the day before the purported
transfer of such stock. The record holder of the common or preferred stock that
are designated as Shares-in-Trust will be required to submit such number of
shares of stock to the trust and the beneficiary of the trust will be one or
more charitable organizations that are named by us.

INABILITY TO RETAIN EARNINGS

        In order to qualify as a REIT, we generally are required each year to
distribute to our shareholders at least 95% of our net taxable income (excluding
any net capital gain). In addition, we are subject to a 4% nondeductible excise
tax on the amount, if any, by which certain distributions paid by us with
respect to any calendar year are less than the sum of (i) 85% of our ordinary
income, (ii) 95% of our capital gain net income for that year, and (iii) any
undistributed taxable income from prior periods. We intend to continue to make
distributions to our shareholders to comply with the 95% distribution
requirement and to avoid the nondeductible excise tax. Differences in timing
between taxable income and cash available for distribution to our shareholders
due to the seasonality of the hospitality industry could require us to borrow
funds on a short-term basis to meet the 95% distribution requirement and to
avoid the nondeductible excise tax.

THE COMPANY MAY NOT BE ABLE TO CONTINUE ITS EXTERNAL GROWTH RATE

        Our growth strategy has been to acquire underperforming and
undercapitalized hotels located in strong markets where we believe significant
barriers to entry exist. We then seek to improve the hotels' financial
performance by renovating, redeveloping, and repositioning the hotels and
requiring the Lessee to implement a focused sales and marketing program. The
current conditions in the equity and debt capital markets limit our ability to
access new capital on favorable terms. Because of the reasons discussed under
"Risk Factors - Liquidity," we do not have access on acceptable terms to
additional capital to fund acquisitions of additional hotels. Therefore, we do
not currently anticipate acquiring any additional hotel assets for the remainder
of 1999. Accordingly, we cannot assure you that our external growth rate will
equal or exceed our recent historical external growth rate.

ENVIRONMENTAL RISKS

        Various federal, state and local laws subject property owners or
operators to liability for the costs of removal or remediation of certain
hazardous substances released on property. These laws often impose liability
without regard to whether the owner or operator knew of, or was responsible for,
the release of the hazardous substances. The presence of or the failure to
properly remediate hazardous substances may adversely affect occupancy of a
contaminated hotel property, the ability to operate hotels, and our ability to
sell or borrow against contaminated properties. In addition to the costs
associated with investigation and remediation actions brought by governmental
agencies, the presence of hazardous waste on a property could result in personal
injury or similar claims or lawsuits.

        Various laws also impose, on persons who arrange for the disposal or
treatment of hazardous or toxic substances, liability for the cost of removal or
remediation of hazardous or toxic substances at the disposal or treatment
facility. These laws often impose liability whether or not the person arranging
for the disposal ever owned or operated the disposal facility. The obligation to
pay for these costs or our inability to pay for such costs, could adversely
affect our operating costs and the value of our properties.

        Phase I environmental site assessments have been obtained on all of our
owned properties. The purpose of Phase I environmental site assessments is to
identify potential sources of contamination for which an owner may be
responsible and to assess the status of environmental regulatory compliance.
None of the environmental site assessments revealed any environmental condition,
liability or compliance concern that we believe would have a material adverse
affect on our business, assets or results of operations. Nor are we aware of any
such condition, liability or concern by any other means. However, it is possible
that the environmental site assessments relating to any one of the properties
did not reveal all environmental conditions, liabilities or compliance concerns
that arose at a property before or after the related review was completed.

REAL ESTATE INVESTMENT RISKS IN GENERAL

        Each of our hotels are subject to a variety of risks associated with
real estate ownership. Some of these risks include:

        o   Changes in national and local economic conditions;

        o   Changes in interest rates;

        o   Changes in costs of, or terms of, loans from lenders;

        o   Changes in environmental laws;

        o   The ongoing requirement to make capital improvements, repairs or
            maintenance;

        o   Changes in the tax rates or laws;

        o   The continuing requirement to pay operating expenses;

        o   Changes in governmental requirements or zoning laws;

        o   Occurrences beyond the control of an owner, such as natural
            disasters like earthquakes and weather, civil unrest or so-called
            "acts of God;"

        o   The possibility of unexpected, uninsured or under-insured losses;
            and

        o   Condemnation by a government agency seeking to use a property for a
            public purpose.


                                       33


<PAGE>   34

        Risks such as those listed above, and other risks which may occur from
time to time, may adversely affect our profit from the property because they
cause increased costs, expenses, liabilities, restrictions and operational
delays. Such risks may also affect the price we may obtain on a sale of a
property or whether the property can be sold at all.

UNINSURED AND UNDER-INSURED LOSSES

        We carry comprehensive policies of insurance for our hotels which
include liability for personal injury, property damage, fire and extended
coverage. We believe the coverage we carry is typical and customary for owners
of hotels such as ours. Even though we carry the insurance referenced above,
certain losses may be uninsurable by virtue of the type or amount of loss.
Losses which result from catastrophes, such as hurricanes, tornadoes,
earthquakes, floods or so-called "acts of God," may fall within that category.
More than half of our hotels are located in California and the Pacific
northwest, an area which is subject to a high degree of seismic activity and
risk. Although we carry earthquake insurance for our hotels, there is no
assurance that such insurance will be available in the future under terms and
amounts which are sufficient to provide adequate protection. It also could be
possible that the current insurance coverage we carry would not be sufficient to
pay the full market value or replacement cost of an affected hotel with a
resulting loss of our entire investment. Therefore, a possibility does exist for
substantial uninsured or under-insured losses as a result of an earthquake.

        Other factors also affect whether a loss is uninsured or under-insured
and may include inflation, changes in law or environmental contamination. Such
factors may affect whether insurance proceeds received by us are adequate to
restore our entire investment in the property. Factors such as these may also
make it impractical to use insurance proceeds to replace or repair our property
after it has been damaged or destroyed.

BECAUSE REAL ESTATE INVESTMENTS ARE ILLIQUID, WE MAY NOT BE ABLE TO SELL
PROPERTIES WHEN APPROPRIATE

        Real estate investments generally cannot be sold quickly. We may not be
able to vary our portfolio promptly in response to economic or other conditions.
Further, in order to cure our non-compliance with the financial covenants in our
Credit Facility, we may need to sell assets and use the proceeds to pay down the
outstanding balance. This inability to quickly sell our assets on favorable
terms could adversely affect our financial condition and ability to service debt
and make distributions to our shareholders.

OUR EARNINGS AND CASH DISTRIBUTIONS WILL AFFECT THE MARKET PRICE OF OUR PUBLICLY
TRADED SECURITIES

        We believe that the market value of a REIT's equity securities is based
primarily upon the market's perception of the REIT's growth potential and its
current and potential future cash distributions, and is secondarily based upon
the real estate market value of the underlying assets. For that reason, REIT
shares may trade at prices that are higher or lower than the net asset value per
share. In particular, if we reduce or suspend our distributions to stockholders,
which we are doing pending closing of the Merger with SHP as evidenced by our
failure to pay a dividend for the quarter ended June 30, 1999 the price of our
shares may decline.

YEAR 2000 ISSUE

        The term "Year 2000 Issue" is a general term used to describe the
complications that may be caused by existing computer hardware and software that
were designed by the respective manufacturers without consideration of the
upcoming change in the century. Many computer systems recognize calendar years
by the last two digits in the date code field. Beginning in the year 2000, these
date code fields will need to accept four digit entries to distinguish
twenty-first century dates from twentieth century dates. If not corrected,
computer systems may fail or create erroneous results which could have
significant negative operational and financial consequences. We have adopted a
Year 2000 Compliance Program (the "Compliance Program") to minimize disruptions
to our business which could be caused by computer system error or failure. These
computerized systems include information and non-information technology systems
and applications, as well as, financial and operational reporting systems. For
discussion of the Company's and the Lessee's efforts to address the Year 2000
issue and the related Compliance Program see "Management's Discussion and
Analysis of Financial Condition and Results of Operations, Year 2000 Issue."


                                       34


<PAGE>   35

        There can be no assurances that our Compliance Program will be properly
and timely completed, and failure to do so could have a material adverse effect
our business operations and financial condition. We cannot predict the actual
effects of the Year 2000 Issue on our business operations and financial
condition. The actual effects may be impacted by: (i) whether significant third
parties properly and timely address the Year 2000 Issue; and (ii) whether
broad-based or systemic economic failures may occur. We are also unable to
predict the severity and duration of any such failures, which could include
disruptions in passenger transportation or transportation systems generally,
loss of utility and telecommunications services, the loss or disruption of hotel
reservations made on centralized reservation systems and errors or failures in
financial transactions or payment processing systems such as credit cards. Due
to the general uncertainty inherent in the Year 2000 Issue and our dependence on
third parties, we are unable to determine at this time whether the consequences
of Year 2000 failures will have a material impact on us. Our Compliance Program
is expected to significantly reduce the level of uncertainty about the Year 2000
Issue and we believe that the possibility of significant interruptions of normal
operations should be reduced.

MARKET INTEREST RATES MAY HAVE AN EFFECT ON THE VALUE OF OUR PUBLICLY TRADED
SECURITIES

        One of the factors that investors consider important in deciding whether
to buy or sell shares of a REIT is the distribution rate on such shares (as a
percentage of the price of such shares) relative to market interest rates. If
market interest rates go up, prospective purchasers of REIT shares may expect a
higher distribution rate. Higher interest rates would not, however, result in
more funds for us to distribute and, in fact, would likely increase our
borrowing costs and potentially decrease funds available for distribution. Thus,
the higher market interest rates could cause the market price of our publicly
traded securities to go down.

HOTEL INDUSTRY RISKS

        Operating Risks. In addition to the investment risks associated with
investing all of our resources in the hotel industry, we face operating risks
associated with hotels. These risks include, among others, the following:

        o   Competition for customers at our hotels from other hotels, many of
            which are owned by competitors who have significantly greater
            financial resources and marketing power and therefore compete with
            our hotels;

        o   The risk of loss of market share in areas in which overbuilding
            occurs and adversely affects occupancy, ADR and REVPAR;

        o   Erosion of operating margins arising from an increase in operating
            costs due to inflation or other factors that may exceed increases in
            REVPAR;

        o   Dependence on demand for our accommodations from both business
            travelers, commercial travelers and tourism, each of which may be
            affected in different markets by different economic factors;

        o   Strikes and other labor disturbances by the Lessee's employees which
            would seriously disrupt the Lessee's ability to provide services to
            hotel guests;

        o   The deterioration of economic conditions either generally or in
            particular markets in which our hotels are located causing a
            reduction in demand for our accommodations.

        The Lessee's operating results at our hotels are directly affected by
the factors described above and a significant decrease in operating revenues by
the Lessee will adversely affect the Lessee's ability to make payments of rent
under the percentage leases. Any reduction in such rent will reduce our cash and
could adversely affect our ability to make distributions to our stockholders.

        Seasonality of Hotel Business and Our Hotels. The hotel industry in
general is seasonal with certain periods generating greater revenues than
others. In particular, our revenues are greater in the second and the third
quarters than in the first and the fourth quarters. In addition, winter weather
in the markets in which our hotels operate can severely impact the operating
results of particular hotels. The Lessee's revenues can vary significantly from
quarter to quarter. It is possible that the significant fluctuation of revenues
in a particular quarter due to weather or other factors could cause us to earn
less percentage rent than we had originally anticipated which could have an
adverse effect on our ability to make distributions to our shareholders.


                                       35


<PAGE>   36

        Increased Competition from Overbuilding. The hotel industry has
historically experienced cycles of overbuilding in certain geographic markets
and product segments. This overbuilding increases competition for hotel guests,
resulting in lower occupancies and lower ADRs thereby reducing revenues of the
hotels effected by the increased competition. While our investment strategy is
to acquire underperforming hotels in markets where we believe there are
significant barriers to entry, we can give no assurance that the current hotel
development activities, particularly in the limited service segment, will not
create additional significant competition for our hotels. This increased
competition would reduce the revenues generated by the Lessee at the effected
hotel, thus reducing percentage rent we receive and therefore potentially
adversely effecting our distributions to our shareholders.

        Impact of Increased Operating Costs and Capital Expenditures. Our hotels
need to be periodically renovated and furniture, fixtures and equipment replaced
in order to remain competitive in their markets and to comply with the terms of
franchise agreements under which our hotels are operated. Under our Percentage
Leases, we are obligated to make available to the Lessee for periodic
refurbishment of furniture, fixtures and equipment an amount equal to four
percent (4%) of the room revenues of each hotel. Our ability to fund these and
other capital expenditures including periodic replacement of furniture, fixtures
and equipment will depend in part on the financial performance of the Lessee and
our hotels. If these expenditures exceed our estimates, then the increased costs
would adversely effect the cash available for other purposes such as making
distributions to our stockholders. Alternatively, if we fail to make these
expenditures, we may adversely effect the competitive position of the hotels and
have an adverse effect on occupancy rates, ADRs and REVPAR. In certain
instances, our failure to make certain capital expenditures may constitute a
default under the applicable franchise agreement.

RISKS OF OPERATING UNDER FRANCHISE AGREEMENTS

        Of our 59 hotels, 57 are operated under franchise agreements with
national franchisors. The Lessee is the franchisee and is responsible for
complying with the franchise agreements. Under these arrangements, a franchisor
provides marketing service and room reservations and certain other operating
assistance, but requires the Lessee to pay significant fees as well as maintain
the hotel in a certain condition. If the Lessee fails to maintain these required
standards or we fail to make required capital expenditures (or to fund the
Lessee's expenditures) then there may be a termination of the franchise
agreement and possible liability for damages. If the Lessee were to lose a
franchise on a particular hotel, it could have a material adverse effect upon
the operation, financing or value of that hotel due to the loss of the franchise
name, marketing support and centralized reservation system. In addition, adverse
publicity affecting a franchisor could reduce the revenues we receive from the
hotels subject to such franchise. Any loss of revenues by the Lessee at a hotel
because of loss of the franchise agreement would adversely effect the Lessee's
ability to pay rent and could effect our ability to make distributions to our
stockholders.

OUR DEGREE OF LEVERAGE COULD LIMIT OUR ABILITY TO OBTAIN ADDITIONAL FINANCING

        Our Articles of Incorporation limits consolidated indebtedness to 50% of
our investment in hotel properties, at cost on a consolidated basis, after
giving effect to our use of proceeds from the indebtedness. As of September 30,
1999, our ratio of debt to total investment in hotel properties and other real
estate investments was approximately 45%. Our Credit Facility has further
restrictions on the amount of Company indebtedness. The degree of leverage could
have important consequences to our stockholders, including, effecting our
ability to obtain additional financing in the future for working capital,
capital expenditures, acquisitions, development or other general corporate
purposes including the payment of distributions and could make us more
vulnerable to a downturn in business or the economy. Further, increases in our
cost of borrowing will reduce the cash available to make distributions to our
stockholders
