                    PRIME HOSPITALITY CORP. AND SUBSIDIARIES
               NOTES TO INTERIM CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)

NOTE 1 -   BASIS OF PRESENTATION

           In the opinion of management, the accompanying interim unaudited
consolidated financial statements of Prime Hospitality Corp. and subsidiaries
(the "Company") contain all material adjustments, consisting of normal recurring
adjustments, necessary to present fairly the financial position of the Company
as of September 30, 1999 and the results of its operations for the three and
nine months ended September 30, 1998 and 1999 and cash flows for the nine months
ended September 30, 1998 and 1999.

           The consolidated financial statements for the three and nine months
ended September 30, 1998 and 1999 were prepared on a consistent basis with the
audited consolidated financial statements for the year ended December 31, 1998.
Certain reclassifications have been made to the September 30, 1998 consolidated
financial statements to conform them to the September 30, 1999 presentation.

           The consolidated results of operations for the three and nine months
ended September 30, 1999 are not necessarily indicative of the results to be
expected for the full year. These interim unaudited consolidated financial
statements should be 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.

NOTE 2 -   ACCOUNTING POLICIES

           In January 1999, the Company adopted Statement of Position 98-5,
"Reporting on the Costs of Start-Up Activities" (SOP 98-5). The Company has
recorded a $5.3 million charge, net of taxes, for the cumulative effect of a
change in accounting principle to write off any unamortized pre-opening costs
that remained on the balance sheet at the date of adoption. Additionally,
subsequent to the adoption of this new standard, all future pre-opening costs
are expensed as incurred.

           In June 1998, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards No. 133, "Accounting for Derivative
Instruments and Hedging Activities" (SFAS 133) which is effective for fiscal
years beginning after June 15, 2000. SFAS 133 establishes accounting and
reporting standards requiring that every derivative instrument (including
certain derivative instruments embedded in other contracts) be recorded on the
balance sheet as either an asset or liability measured at its fair value. SFAS
133 requires that changes in the derivative's fair value be recognized currently
in earnings unless specific hedge accounting criteria are met. The Company has
not yet quantified the impact of adopting SFAS 133 on its financial statements.
However, the Company believes that the adoption of SFAS 133 will not have a
material effect on its financial condition or results of its operations.

NOTE 3 -   HOTEL DISPOSITIONS

           During the nine months ended September 30, 1999, the Company sold
seven AmeriSuites hotels, located in Austin, TX, Chicago, IL, Houston, TX,
Irving, TX, San Antonio, TX, Portland, ME and Dublin, CA, for $70.3 million. The
transactions generated net gains of $8.0 million and provide for the Company to
generate franchise fees under ten to twenty year franchise agreements.

           During the nine months ended September 30, 1999, the Company also
sold one HomeGate Studios and Suites hotel located in Grand Prairie, TX, an
apartment building in Charlotte, NC and a vacant land parcel located in Chicago,
IL for total proceeds of $3.2 million. The transactions generated a net loss of
$967,000.

           The Company also had a contract to sell and lease back nine
additional full-service hotels to MeriStar Hospitality Corp. not later than
March 31, 1999. In February 1999, MeriStar informed the Company that it was
unable to fulfill its contractual obligation. Under the terms of the contract,
the Company received a $4.0 million contract termination fee in February 1999.
This fee is included in other income for the nine months ended September 30,
1999.

           During the quarter ended September 30, 1999, the Company entered into
a contract to sell its Frenchman's Reef Marriott Resort Hotel ("Frenchman's
Reef") located in St. Thomas U.S.V.I. to Marriott International, Inc. The
closing of the transaction is subject to certain conditions which are required
to be satisfied during the fourth quarter 1999.

           During the quarter ended September 30, 1999, the Company entered into
a contract to sell its remaining five HomeGate hotels. The closing of this
transaction is expected to occur during the fourth quarter 1999.

NOTE 4 -   EARNINGS PER COMMON SHARE

           Basic earnings per common share was computed based on the weighted
average number of common shares outstanding during each period. The weighted
average number of common shares used in computing basic earnings per share was
53.7 million and 51.1 million for the three months ended September 30, 1998 and
1999, respectively, and 51.1 million and 51.6 million for the nine months ended
September 30, 1998 and 1999, respectively.

           Diluted earnings per share reflects adjustments to basic earnings per
share for the dilutive effect of stock options and warrants and in 1998, the
elimination of interest expense and the issuance of additional common shares
from the conversion of the Company's 7% convertible subordinated notes. The
weighted average number of common shares used in computing diluted earnings per
share was 54.2 million and 52.1 million for the three months ended September 30,
1998 and 1999, respectively, and 54.9 million and 52.8 million for the nine
months ended September 30, 1998 and 1999, respectively.

NOTE 5 -   INTEREST EXPENSE

           The Company capitalizes interest related to borrowings used to
finance hotel construction. Capitalized interest was approximately $6.4 million
and $1.7 million for the three months ended September 30, 1998 and 1999,
respectively, and $20.3 million and $10.2 million for the nine months ended
September 30, 1998 and 1999, respectively. Also included in interest expense is
the amortization of deferred financing fees of $763,000 and $784,000 for the
three months ended September 30, 1998 and 1999, respectively, and approximately
$2.3 million for each of the nine month periods ended September 30, 1998 and
1999.

NOTE 6  -  TREASURY STOCK

           Under its stock repurchase program, the Company purchased
approximately 3.6 million shares of its common stock at an average price of
$10.08 per share during the nine months ended September 30, 1999. In October
1999, the Company purchased an additional 1.8 million shares of its common stock
for $14.7 million, bringing the total purchases in 1999 to 5.4 million shares at
a total cost of $50.0 million. In October 1999, the Company's Board of Directors
approved the repurchase of an additional $100.0 million of its common stock.
Under the terms of the Company's $200 Million Revolving Credit Facility (the
"Revolving Credit Facility"), the Company was allowed to repurchase shares in an
aggregate amount not to exceed $50 million through December 1999. In October
1999, the Revolving Credit Facility was amended to allow an additional $100
million of share repurchases. The purchase of these additional shares are
limited to 50% of the proceeds from asset sales.

           During the quarter ended September 30, 1999, the Company entered into
contracts to sell its Frenchman's Reef Marriott Resort hotel and five
non-prototype HomeGate hotels. In accordance with SFAS 121, "Accounting for the
Impairment of Long-Lived Assets to be Disposed of," the Company has reduced the
carrying value of the these assets to reflect their estimated fair value.

NOTE 9 -   OTHER INCOME

           Other income consists of income from property transactions and other
asset sales and retirements. For the three months ended September 30, 1999,
other income consisted of $2.8 million related to net gains on property
transactions. For the nine months ended September 30, 1999, other income
consisted of net gains on property transactions of $7.0 million, losses on the
sales of marketable securities of $4.8 million and a contract termination fee
income of $4.0 million (See Note 3). For the three and nine months ended
September 30, 1998, other income consisted of gains on the settlement of notes
receivable of $18.4 million.

NOTE 10 -  GEOGRAPHIC AND BUSINESS INFORMATION

           Through October 31, 1999, the Company's hotels operated in four major
lodging industry segments: the all-suites segment, under its AmeriSuites brand;
the extended-stay segment, under its HomeGates brand; the limited-service
segment, primarily under its Wellesley Inns brand; and the full-service segment
under major national franchises. As of November 1, 1999, the Company ceased its
extended-stay operations as it converted 38 of its 43 HomeGate hotels to its
Wellesley Inn and Suites brand and signed a contract to sell its five remaining
HomeGate hotels.

PART I.    FINANCIAL INFORMATION

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

GENERAL

           The Company is an owner, manager and franchisor of hotels throughout
the United States and the U.S. Virgin Islands. The Company owns two proprietary
brands, AmeriSuites (all-suites), and Wellesley Inn & Suites (limited-service).
Also within its portfolio are owned and/or managed hotels operated under
franchise agreements with national hotel chains. As of October 31, 1999, the
Company owned 157 hotels (the "Owned Hotels"), operated 28 hotels under lease
agreements primarily with real estate investment trusts ("REITS") (the "Leased
Hotels"), managed 16 hotels for third parties (the "Managed Hotels") and
franchised 8 hotels, which it does not operate (the "Franchised Hotels"). The
Company has significant equity interests in the Owned Hotels and has economic
interests limited to a percentage of revenues (generally between 2.5% to 5.0%)
on the Leased Hotels, Managed Hotels and Franchised Hotels. The Company
consolidates the results of operations of its Owned Hotels and Leased Hotels and
records management fees (including incentive management fees) on the Managed
Hotels and franchise revenue on the Franchised Hotels.

           The Company's strategy is to develop its proprietary AmeriSuites and
Wellesley Inn and Suites brands both through corporate development and
franchising. The Company currently has 97 AmeriSuites and 66 Wellesley Inn and
Suites in operation. Through the development of its proprietary brands, the
Company is transforming itself from an owner/operator into a franchisor and
manager and has positioned itself to generate additional revenues with minimal
capital investment. Since it received approval to begin franchising in mid 1998,
Prime has executed 27 new AmeriSuites franchise agreements and has 32
applications (30 AmeriSuites) pending. In addition, construction is currently
underway on six of these sites with construction scheduled to begin on three
additional franchised sites in the fourth quarter.

           On November 1, 1999, the Company converted 38 of its 43 extended-stay
HomeGate hotels into its limited-service Wellesley Inn and Suites brand. The
Company also signed a contract to sell the remaining five HomeGate hotels. The
conversion will change the hotels' customer base from extended-stay to
transient. The Company believes this will enhance the value of its existing
hotels, create efficiencies by adding critical mass to the chain and improve its
franchising prospects for the Wellesley Inn and Suites brand.

           For the three months ended September 30, 1999, earnings before asset
transactions and other charges increased from $13.0 million in 1998 to $14.6
million in 1999. The results were impacted by the effect of capitalized interest
which was $4.7 million less during the period than the same period in 1998 due
to the lower levels of construction activity in 1999.

           Earnings before interest, taxes, depreciation and amortization
(EBITDA) increased by 32.4% to $ 46.9 million for the three months ended
September 30, 1999. Hotel EBITDA increased by 24.5% to $45.9 million for the
three month period. Hotel EBITDA represents EBITDA generated

                                      -10-
<PAGE>   13


from the operations of Owned Hotels and excludes management fee income, interest
income from mortgages and notes receivable, general and administrative expenses
and other revenues and expenses which do not directly relate to the operations
of Owned Hotels. The changes in EBITDA and Hotel EBITDA are primarily
attributable to the growth at comparable hotels and the addition of new hotels
and are offset by rent expense associated with the sale/leaseback of hotels.

           During the nine months ended September 30 1998 and 1999, the
Company's hotels operated in four segments of the industry: the upscale
all-suites segment, under the Company's proprietary AmeriSuites brand; the
upscale full-service segment, under major national franchises; the mid-price
limited-service segment, primarily under the Company's proprietary Wellesley Inn
& Suites brand; and the mid-price extended-stay segment, under the Company's
proprietary HomeGate Studios & Suites brand. The following table illustrates the
Hotel EBITDA contribution from each segment (in thousands):

</TABLE>


     Hotel EBITDA for the three and nine months ended September 30, 1999
continued to reflect the shifting mix in the Company's hotel portfolio toward
its proprietary brands. Based on the number of new hotels opened during 1999,
the Company expects the relative contribution from its proprietary brands to
continue to increase. Additionally, with the conversion of 38 of its 43
extended-stay HomeGate hotels into the limited-service Wellesley Inn and Suites
brand and the sale of its remaining five HomeGate hotels, the Company's hotels
will no longer operate in the extended-stay segment.

     EBITDA and Hotel EBITDA are not measures of financial performance under
generally accepted accounting principles and should not be considered as
alternatives to net income, as an indicator of the Company's operating
performance or as alternatives to cash flows as a measure of liquidity.

           Lodging revenues, which include room revenues and other related
revenues such as telephone and vending, increased by $19.1 million and $73.8
million, or 18.2% and 25.3%, respectively, for the three and nine months ended
September 30, 1999, as compared to the same periods in 1998. Lodging revenues
for the three months ended September 30, 1999 increased due to incremental
revenues of $16.9 million from new hotels and higher revenues for comparable
Owned Hotels, which increased by $1.5 million, or 2.2%. Lodging revenues for the
nine months ended September 30, 1999 also increased due to incremental revenues
of $59.2 million from new hotels and higher revenues for comparable Owned
Hotels, which increased by $3.7 million or 2.2%.

           The following table sets forth hotel operating data for the
comparable Owned Hotels for the three and nine months ended September 30, 1999

           The results for the three months ended September 30, 1999 were
impacted by Hurricane Floyd, which the Company estimates resulted in lost
revenues of approximately $2.0 million. Excluding the effects of Hurricane
Floyd, the Company estimates its REVPAR growth would have approximated 3.6%.

           The improvements in REVPAR at comparable Owned Hotels were generated
by higher occupancy percentages which rose by approximately 1%, for the three
and nine month periods, and increases in ADR of 1.3% and .7% for the three and
nine month periods, respectively.

           Food and beverage revenues for the three months ended September 30,
1999 decreased by $100,000, or 1.1%, as compared to the same period in the prior
year due to decreased lounge and restaurant business. Food and beverage revenues
for the nine months ended September 30, 1999 increased by $2.5 million, or 6.7%,
as compared to the same period in 1998 primarily attributable to an increase in
revenues of $2.8 million at the Frenchman's Reef Marriott hotel in St. Thomas
U.S.V.I. (the "Frenchman's Reef"). Food and beverage revenues for comparable
Owned Hotels was also slightly down for the three and nine month periods, due to
a decrease in the lounge and restaurant business.

           Management, franchise and other revenue consists primarily of base,
incentive and other fees earned under management agreements, royalty fees earned
under franchise agreements, rental income and business interruption insurance
revenue in 1998 related to hurricane damage at the Frenchman's Reef. Management,
franchise and other revenue excluding business interruption insurance increased
by $1.5 million and $1.7 million, or 45.5% and 16.7%, for the three and nine
months ended September 30, 1999 as compared to the same periods in 1998 due to
additional Managed Hotels and Franchised Hotels. Business interruption insurance
revenue of $900,000 and $4.0 million were recorded for the three and nine months
ended September 30, 1998 and were based on a settlement in March 1998 of the
Company's claim related to the damage at the Frenchmen's Reef caused by
Hurricane Bertha in July 1996.

           Interest on mortgages and notes receivable primarily relates to
mortgages secured by certain Managed Hotels. Interest on mortgages and notes
receivable increased by $200,000 for the three months ended September 30, 1999
as compared to the same period in 1998 due to the settlement of various cash
flow notes during the quarter. Interest on mortgages and notes receivable
decreased by $1.2 million or 35.8%, for the nine months ended September 30, 1999
as compared to the same period in 1998 primarily due to the settlement of
various cash flow mortgages and notes receivable in 1998.

           Direct lodging expenses increased by $5.8 million and $20.7 million,
or 21.7% and 29.1%, respectively, for the three and nine months ended September
30, 1999, respectively, as compared to the same periods in 1998 due primarily to
the addition of new hotels. Direct lodging expenses, as a percentage of lodging
revenue, increased from 25.2% to 26.0% for the three month period and from 24.4%
to 25.1% for the nine month period. For comparable Owned Hotels, direct lodging
expenses as a percentage of lodging revenues increased from 24.8% to 25.1% for
the three month period and from 24.1% to 24.6% for the nine month period. The
increases were primarily due to higher travel agent commissions and hotel
payroll.

           Direct food and beverage expenses for the three and nine months ended
September 30, 1999 decreased by approximately $300,000 and $200,000, or 3.2% and
0.6%, respectively, as compared to the same periods in 1998. As a percentage of
food and beverage revenues, direct food and beverage expenses decreased from
80.5% to 78.8% for the three month period and decreased from 77.0% to 71.7% for
the nine month period.

                                      -15-

For comparable Owned Hotels, food and beverage expenses as a percentage of food
and beverage revenues increased from 78.9% to 80.3% for the three month period
and remained at 78.1% for the nine month period. The decreases were attributed
to the higher margins generated at the Frenchman's Reef.

           Direct hotel selling and general expenses consist primarily of hotel
expenses for Owned Hotels which are not specifically allocated to rooms or food
and beverage activities, such as administration, selling and advertising,
utilities, repairs and maintenance. Direct hotel selling and general expenses
increased by $2.7 million and $14.6 million, or 10.2% and 20.0%, respectively,
for the three and nine months ended September 30, 1999 as compared to the same
periods in 1998 due primarily to the addition of new hotels. As a percentage of
hotel revenues (defined as lodging and food and beverage revenues), direct hotel
selling and general expenses decreased from 23.0% to 21.8% for the three month
period and from 22.1% to 21.6% for the nine month period. For the comparable
Owned Hotels, direct hotel selling and general as a percentage of hotel revenues
decreased from 21.3% to 20.4% for the three month period and from 20.8% to 20.7%
for the nine month period. The decreases in the total and comparable expense
margins were primarily due to lower liability insurance costs and, in the first
quarter, decreases in weather-related costs.

           Occupancy and other operating expenses consist primarily of
insurance, real estate and other taxes and rent expense. Occupancy and other
operating expenses increased by $700,000 and $11.3 million, or 4.3% and 26.4%,
respectively, as compared to the same periods in 1998 due to the rent expense
associated with the sale/leaseback of hotels in 1998 and the addition of new
hotels. Occupancy and other operating expenses as a percentage of hotel revenues
decreased from 14.2% to 12.8% for the three month period and increased from
12.9% to 13.3% for the nine month period due to rent expense associated with the
sale/leasebacks.

           General and administrative expenses consist primarily of centralized
management expenses such as operations management, sales and marketing, finance
and hotel support services associated with operating both the Owned Hotels and
Managed Hotels and general corporate expenses. General and administrative
expenses decreased by $600,000, or 9%, for the three months ended September 30,
1999 as compared to the same period in 1998 primarily due to a restructuring of
the Company's corporate and regional hotel operations. For the nine months ended
September 30, 1999, general and administrative expenses increased by $1.9
million, or 10%, as compared to the same period in 1998 due to increased
advertising, personnel and training costs associated with opening the new
AmeriSuites hotels and costs associated with the Company's franchising efforts.
As a percentage of total revenues, general and administrative expenses decreased
from 5.5% to 4.3% for the three month period and from 5.7% to 5.1% for the nine
month period. These decreases were primarily due to the Company's corporate
restructuring.

           Depreciation and amortization expense increased by $1.6 million and
$5.7 million, or 15.8% and 18.6%, respectively, for the three and nine months
ended September 30, 1999 as compared to the same periods in 1998 due to the
impact of new hotel properties.

           Other charges for the three months ended September 30, 1999 consist
of valuation reserves of $4.5 million and $20.0 million related to the Company's
non-prototype HomeGates and its Frenchman's Reef Marriott Beach Resort. In
accordance with SFAS 121, "Accounting for the Impairment of Long-Lived Assets to
be Disposed of," the Company has reduced the carrying value of the assets to
reflect their estimated fair value. For the nine months ended September 30,
1999, other charges consisted of valuation reserves of $27.0 million related to
the non-prototype HomeGates and the Frenchman's Reef and severance charges of
$1.4

million related to the costs associated with the Company's restructuring of
its corporate and regional offices. Other charges for the three months ended
September 30, 1998 consisted of a reserve of $4.0 million associated with the
cost of terminating hotel development projects under contract, $1.4 million for
severance charges related primarily to the resignation of the Company's former
CEO and $1.0 million for hurricane damage at the Frenchman's Reef Marriott
hotel. For the nine months ended September 30, 1998, other charges also includes
a $10.0 million valuation reserve related to its non-prototype HomeGate hotels.

           Investment income decreased by $300,000 and $1.6 million, or 39.3%
and 56.2%, respectively, for the three and nine months ended September 30, 1999
as compared to the same periods in 1998 due to a decreases in dividend income of
$ 81,000 and $910,000, respectively, attributed to the sales of marketable
securities and an overall decrease in the Company's weighted average cash
balance.

           Interest expense increased by $6.1 million and $14.0 million, or
109.9% and 82.1%, respectively, for the three and nine months ended September
30, 1999 as compared to the same periods in 1998, primarily due to a reduction
in the amount of interest capitalized. Capitalized interest decreased from $6.4
million to $1.7 million for the three month periods ended September 30, 1998 and
1999, and from $20.3 million to $10.2 million for the nine month periods ended
September 30, 1998 and 1999 due to the lower levels of construction activity in
1999.

           Other income consists of income from property transactions and other
asset sales and retirements. For the three months ended September 30, 1999,
other income consisted of $2.8 million related to net gains on property
transactions. For the nine months ended September 30, 1999, other income
consisted of net gains on property transactions of $7.0 million, losses on the
sales of marketable securities of $4.8 million and million contract termination
fee income of $4.0 million. For the three and nine months ended September 30,
1998, other income consisted of gains on the settlement of notes receivable of
$18.4 million.

LIQUIDITY AND CAPITAL RESOURCES

           At September 30, 1999, the Company had cash, cash equivalents and
current marketable securities of $32.8 million. In addition, at September 30,
1999, the Company had $53.5 million available under the Revolving Credit
Facility.

           The Company's major sources of cash for the nine months ended
September 30, 1999 were net proceeds from the sale of seven AmeriSuites hotels
and certain other assets, of $73.5 million, borrowings of $22.6 million and cash
flow from operations of $68.5 million. The Company's principal uses of cash
during the period were capital expenditures of $90.3 million relating primarily
to the development of new hotels, repurchases of its common stock totaling $36.4
million and $47.5 million of debt repayment, primarily related to the Revolving
Credit Facility.

           For the nine months ended September 30, 1998 and 1999, cash flow from
operations was positively impacted by the utilization of net operating loss
carryforwards ("NOLs") of $4.8 million and $2.3 million, respectively. At
September 30, 1999, the Company had federal NOLs relating primarily to its
predecessor, Prime Motor Inns, Inc., of approximately $65.5 million which are
subject to annual utilization limitations and will expire in 2006.

           Sources of Capital. The Company has undertaken a strategic initiative
to dispose of hotel real estate and to invest the proceeds in the growth of its
proprietary brands. Due to the uncertainty in the hotel divestiture markets, the
Company's business plan does not depend on any material proceeds from asset
sales. During the nine months ended September 30, 1999, the Company sold seven
AmeriSuites hotels, one HomeGate hotel and a vacant land parcel and realized
$73.5 million in cash proceeds. The Company is currently negotiating additional
sales of AmeriSuites hotels and has signed contracts to sell the Frenchman's
Reef hotel and its remaining five HomeGate hotels.

           The Company has a $200.0 million Revolving Credit Facility which
bears interest at LIBOR plus 2%. The facility is available through 2001 and may
be extended for an additional year. Borrowings under the facility are secured by
certain of the Company's hotels with recourse to the Company. Additional
properties may be added subject to the approval of the lenders. Availability
under the facility is subject to a borrowing base test and certain other
covenants. At September 30, 1999, the Company had outstanding borrowings of
$146.5 million under the facility and further availability of $53.5 million.

           The Company had a contract to sell and lease back nine additional
full-service hotels to MeriStar not later than March 31, 1999. In February 1999,
MeriStar informed the Company that it was unable to fulfill its contractual
obligation. Under the terms of its contract, the Company received a one-time
$4.0 million contract termination fee in February 1999.

           Uses of Capital. The Company's capital spending has been focused on
the completion of its 1998 AmeriSuites and HomeGate development pipeline. In
October 1999, the Company completed its 1998 development pipeline with the
opening of its first Wellesley Inn and Suites hotel in Columbia, SC. For the
nine months ended September 30, 1999, the Company opened 21 new hotels and spent
$74.9 million on new construction. Prime has resumed new corporate development
with the commencement of construction of two AmeriSuites hotel in the Baltimore
and Orlando markets and is reviewing plans to construct AmeriSuites on sites it
already owns in the Detroit, San Jose and San Francisco areas. The Company plans
to spend approximately $5.0 million on these new AmeriSuites during the last
quarter of 1999 and approximately $40 million in 2000. These amounts are to be
funded by internally generated cash flow. In addition, for the nine months ended
September 30, 1999, the Company spent approximately $15.4 million on capital
improvements at its Owned Hotels, which includes the Company's conversion of its
HomeGates Studios and Suites to Wellesley Inn and Suites.

           Under its stock repurchase program, the Company purchased
approximately 3.6 million shares of its common stock at an average price of
$10.08 per share during the nine months ended September 30, 1999. In October
1999, the Company purchased an additional 1.8 million shares of its common stock
for $14.7 million, bringing the total purchases in 1999 to 5.4 million shares at
a total cost of $50.0 million. In October 1999, the Company's Board of Directors
approved the repurchase of an additional $100.0 million of its common stock.
Under the terms of the Company's $200 Million Revolving Credit Facility (the
"Revolving Credit Facility"), the Company was allowed to repurchase shares in an
aggregate amount not to exceed $50 million through December 1999. In October
1999, the Revolving Credit Facility was amended to allow an additional $100
million of share repurchases. The purchase of these additional shares are
limited to 50% of the proceeds from asset sales.

           In order to facilitate future tax-deferred exchanges of hotel
properties, the Company from time to time enters into arrangements with an
unaffiliated third party under Section 1031 of the Internal Revenue Code of
1986, as amended. As of September 30, 1999, the Company had advances of
approximately $ 242.9 million to such third party which advances are classified
as property, equipment and leasehold improvements.

           Year 2000 Readiness. The Company has initiated a program to prepare
the Company's computer systems and applications for the year 2000. This is
necessary because certain computer programs have been written using two digits
rather than four digits to define the applicable year. Any of the Company's
computer programs that have time-sensitive software may recognize a date using
"00" as the year 1900 rather than the year 2000. This could result in a system
failure or miscalculation causing disruptions of operations, including, among
other things, a temporary inability to process normal business transactions. In
addition, many of the Company's vendors and service providers are also faced
with similar issues related to the year 2000.

           In connection with the Company program related to year 2000, the
Company's management has assessed the Company's information systems, including
its hardware and software systems and embedded systems contained in the
Company's hotels and corporate headquarters. Based on the findings of this
assessment, the Company has commenced a plan to upgrade or replace the Company's
hardware or software for year 2000 readiness as well as to assess the year 2000
readiness of the Company's vendors and service providers. In addition, the
Company's management has formulated contingency plans, which, in the event that
the Company is unable to fully achieve year 2000 readiness in a timely manner,
or any of the Company's vendors or service providers fails to achieve year 2000
readiness, may be implemented to minimize the risks of interruptions of the
Company's business.

           Based on its assessment to date of the year 2000 readiness of the
Company's vendors, service providers and other third parties on which the
Company relies for business operations, the Company believes that its principal
vendors, service providers and other third parties are taking action for year
2000 compliance. However, the Company has limited ability to test and control
such third parties' year 2000 readiness, and the Company cannot provide
assurance that failure of such third parties to address the year 2000 issue will
not cause an interruption of the Company's business.

           As of September 30, 1999, the Company believes that approximately 95%
of its information systems are year 2000 ready. The Company estimates that the
total costs associated with implementing year 2000 readiness since the project's
commencement will be in the range of $1.0 to $2.0 million.

           The Company expects to complete the remainder of its year 2000
remediation by November 1999. However, the Company's ability to execute its plan
in a timely manner may be adversely affected by a variety of factors, some of
which are beyond the Company's control including turnover of key employees,
availability and continuity of consultants and the potential for unforeseen
implementation problems. The Company's business could be interrupted if the year
2000 plan is not implemented in a timely manner, if the Company's vendors,
service providers or other third parties are not year 2000 ready or if the
Company's contingency plans are not successful. Based on currently available
information, and although no assurance can be given, the Company does not
believe that any such interruptions are likely to have a material adverse effect
on the Company's results of operations, liquidity or financial condition.
