1. ORGANIZATION AND BASIS OF PRESENTATION

Homegate Hospitality, Inc. (the "Company") was organized in Delaware on August
16, 1996. The Company was capitalized with the issuance of 10 shares of common
stock to Extended Stay Limited Partnership ("ESLP"). The Company was formed to
continue the extended-stay lodging facility development, acquisition and
management operations of ESLP, and to acquire, develop and maintain
extended-stay lodging facilities throughout the United States.

ESLP, a Delaware limited partnership, was formed on February 9, 1996, by ESH
Partners, L.P. ("Crow") and JMI/Greystar Extended Stay Partners, L.P.
("Greystar"), as the general partners, and various limited partners. On October
24, 1996, ESLP was merged with and into the Company. Accordingly, the financial
results of ESLP, the predecessor to the Company, for the period from inception
(February 9, 1996) through September 30, 1996, have been included herein. ESLP
had no operations until June 1996.

The financial statements included herein have been prepared in accordance with
instructions to Form 10-Q and Article 10 of Regulation S-X and therefore do not
include all disclosures required under generally accepted accounting principles
for complete financial statements. In the opinion of management, the financial
statements reflect all adjustments, which consist only of normal recurring
adjustments, necessary for a fair presentation of the financial statements for
the interim periods presented. Interim results of operations are not
necessarily indicative of the results to be expected for the full year. For
further information, refer to the financial statements and footnotes thereto
included in the Company's Annual Report on Form 10-K for the year ended
December 31, 1996.

On July 25, 1997, the Company entered into a definitive merger agreement
("Merger Agreement") with Prime Hospitality Corp. ("Prime") pursuant to which
the Company will merge with a wholly owned subsidiary of Prime. Under the
Merger Agreement, Prime will issue 0.6073 shares of its common stock for each
of the 10,725,000 outstanding shares of the Company's common stock. The Merger
Agreement is subject to the approval of the stockholders of the Company and
other customary terms and conditions. A meeting of the Company's stockholders
has been called for on December 1, 1997 and the merger is expected to be
completed promptly thereafter.





                                                                             6

During the third quarter of 1997, the Company acquired three land parcels in
Austin, Texas, and one in Tampa, Florida that are under development for hotel
construction. Additionally, the Company acquired one land parcel in each of the
following cities: Aurora, Colorado; Orlando, Florida; Columbia, Maryland; and
Columbus, Ohio for future development of hotel facilities. On August 12, 1997
the company purchased an existing corporate housing project in Charlotte, North
Carolina. The Company is intending to convert this project to an extended stay
hotel in 1998. The Company must first obtain the proper zoning for this
conversion to occur. As of September 30, 1997, the Company had entered into
agreements, letters of intent, contracts, or other arrangements for the future
purchase of eleven additional land parcels.

Trammell Crow Residential (TCR) and Greystar Realty Services (GRS) are
developing the hotel facilities under an agreement that expires at the earlier
of the completion of the sixtieth hotel or December 31, 1998.

3. LOANS RECEIVABLE

During 1996, the Company advanced $1,900,500 under two promissory notes to an
unrelated party for the purchase of two parcels of land in Austin, Texas (the
"Rutherford and Jolleyville sites"), on which extended-stay hotel facilities
are being developed. During the first quarter and second quarters of 1997, the
Company advanced an additional $400,000 and $793,837, respectively, under the
notes for various development costs. These notes accrued interest at ten
percent and matured on the sooner of November 2000 or five business days after
demand. On July 3, 1997, the Company purchased the Rutherford and Jolleyville
sites for a total purchase price of $508,713, net of the two promissory notes
and the related accrued interest.

4. NOTE PAYABLE - PRIME HOSPITALITY

In accordance with a commitment letter executed by the Company and Prime
contemporaneously with the execution of the Merger Agreement, the Company and
Prime thereafter executed a loan agreement pursuant to which Prime provided a
$65 million interim secured construction term loan facility ("Construction Term
Loan Facility") to the Company. The Construction Term Loan Facility is to be
used for the acquisition and development of specific sites. The Construction
Term Loan Facility matures and all amounts outstanding thereunder are due at
the earlier of (a) April 1, 1998, (b) the date on which the Company enters into
any agreement (other than the Merger Agreement) with respect to any alternative
proposal or otherwise relating to the merger or sale of substantially all of
the assets of the Company and (c) four months after the termination of the
Merger Agreement. The Company paid a loan fee of 1% of the aggregate principal
amount of the Construction Term Loan Facility. Monthly interest payments
commence December 15, 1997. The interest accrues monthly at a rate of the one
month LIBOR plus 3.5%; provided that the interest rate will increase to the one
month LIBOR plus 5% on the date that is the earlier of (a) November 30, 1997
and (b) the date of the termination of the Merger Agreement (other than a
termination as a result of a breach by Prime). The loan is secured by a first
priority perfected security interest in specified sites. The amount of any loan
under the facility may not exceed 75% of the total project costs of the related
project. The outstanding balance at September 30, 1997 was $23,894,000.

in Charlotte, North Carolina, the Company entered into a $1,900,000 mortgage
note due to Morgan Guaranty Trust Company of New York, with interest at 7.97%
through September 1, 2007. The note is due in monthly installments of
$14,626.77, including interest, from October 1997 through September 2007, and
is secured by the 511 Queens property and improvements. The outstanding balance
at September 30, 1997 was $1,897,992.

In connection with the acquisition of Westar, the Company assumed an
$18,100,000 mortgage note due to Nomura Asset Capital Corporation ("Nomura"),
with interest at 9.71% through January 11, 2011 and thereafter at the greater
of 14.71% or the Treasury Rate plus 9%. The note is due in monthly installments
of $160,789, including interest, from February 1996 through January 2021, and
is secured by the Westar hotel properties and improvements. The outstanding
balance at September 30, 1997 was $17,837,175.

The mortgage note payable to Nomura does not allow for prepayment of the debt
until January 11, 2011, except by providing the lender with U.S. obligations
that produce payments which replicate the payment obligations of the Company
under the note. This restriction represents a substantial prepayment penalty.
On or after January 11, 2011, the loan can be prepaid at any time with no
prepayment penalty.

Restricted cash includes cash retained by Nomura's mortgage servicer for
payment of taxes, insurance and debt service.

OTHER NOTES PAYABLE

The Company has two unsecured notes payable for the purchase of directors and
officers insurance. The notes accrue interest at 6.98% and require monthly
principal and interest payments of $16,497 through July 1999. The outstanding
balance at September 30, 1997 was $338,323.

6. STOCKHOLDERS' EQUITY

EARNINGS PER SHARE

In February 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 128, Earnings per Share ("SFAS No. 128"),
which is required to be adopted on December 31, 1997. At that time, the Company
will be required to change the method currently used to compute earnings per
share and to restate all prior periods.  Under the new requirements for
calculating earnings per share, the dilutive effect of stock options will be
excluded.  Management believes that adoption of SFAS No. 128 will not have a
material effect on earnings per share.



                                                                              11

Item 2. - Management's Discussion and Analysis of Financial Condition and
          Results of Operations

GENERAL

Homegate Hospitality, Inc. ("Homegate") was incorporated in August 1996, to
succeed to the business of Extended Stay Limited Partnership ("ESLP"), which
was organized in February 1996, to become a provider of high quality mid-price
extended-stay hotels. In October 1996, ESLP was merged into Homegate, in
exchange for 6,386,087 shares of common stock.  Hereinafter, Homegate, its
predecessor ESLP, and its subsidiaries are collectively referred to as the
"Company." On October 29, 1996, the Company completed an initial public
offering of 4,325,000 shares of common stock at $11.50 per share.

On July 25, 1997, the Company entered into a definitive merger agreement
("Merger Agreement") with Prime Hospitality Corp. ("Prime") pursuant to which
the Company will merge with a wholly owned subsidiary of Prime. Under the
Merger Agreement, Prime will issue 0.6073 shares of its common stock for each
of the 10,725,000 outstanding shares of the Company's common stock. The Merger
Agreement is subject to the approval of the stockholders of the Company and
other customary terms and conditions. A meeting of the Company's stockholders
has been called for December 1, 1997 and the merger is expected to be completed
promptly thereafter.

The Company, during the period from its inception through September 30, 1997,
completed its concept and product design, market study and initial site
selection activities, and acquired and/or constructed its first properties. As
of September 30, 1997, the Company had 22 employees.

The Company operated nine hotels and one corporate housing project during the
third quarter of 1997. The following is a summary of the Company's operating
properties as of September 30, 1997 and September 30, 1996 by date operations

The Company's average occupancy rate dropped to 52% for the three months ended
September 30, 1997, as compared to 56% for the same period in 1996 resulting in
a 4% decrease in occupancy. The Average Weekly Rate dropped to $258.35 for the
three months ended September 30, 1997, as compared to $276.84 in the same
period in 1996 resulting in a decrease of $18.49. The weekly REVPAR fell to
$134.18 for the three months ended September 30, 1997, as compared to $155.63
for the same period in 1996 resulting in a decrease of $21.45. The decrease in
occupancy, Average Weekly Rate, and weekly REVPAR for the three months ended
September 30, 1997 as compared to the same period in 1996 was significantly
influenced by the loss of 14% of available room nights during the third quarter
of 1997 due to the Westar renovations. After reducing the available room nights
by the number of Westar rooms under renovation, weekly REVPAR would have been
$156.55 for the three months ended September 30, 1997.

The following is a summary of the properties operated during the nine months
ended September 30, 1997 and 1996 and the related Available Room Nights,

The Company's average occupancy rate rose to 57% for the nine months ended
September 30, 1997, as compared to 56% for the same period in 1996 resulting in
a 1% increase in occupancy. The Average Weekly Rate rose to $265.65 for the
nine months ended September 30, 1997, as compared to $229.64 in the same period
in 1996 resulting in a increase of $36.01.  The weekly REVPAR rose to $150.68
for the nine months ended September 30, 1997, as compared to $119.99 for the
same period in 1996 resulting in an increase of $30.69. The increase in
occupancy, Average Weekly Rate, and weekly REVPAR for the nine months ended
September 30, 1997 as compared to the same period for 1996, reflects the
stabilization of three of the extended stay facilities. However, these results
were negatively impacted by the pre-stabilization periods for the two extended
stay facilities (44th and Oak in Phoenix and Denver Tech Center) opened in 1997
and the loss of 13% of available room nights during the nine months ended
September 30, 1997 due to the Westar renovations (see below). After reducing
the available room nights by the number of Westar rooms under renovation,
weekly REVPAR would have been $172.88 for the nine months ended September 30,
1997.

Room revenue increased to $1,955,000 for the third quarter of 1997, as compared
to $630,000 for the same period in 1996 and increased to $5,977,000 for the
nine months ended September 30, 1997, as compared to $655,000 for the same
period in 1996. These increases in room revenue are attributable to the opening
of new or acquired properties in 1996 and 1997.

Property operating expenses increased to $1,463,000 in the third quarter of
1997 as compared to $461,000 in the same period of 1996 and increased to
$4,173,000 for the nine months ended September 30, 1997 as compared to $492,000
for the same period of 1996. These increases are attributable to the opening of
new or acquired properties in 1996 and 1997.

Depreciation and amortization expense applicable to hotel operations increased
to $407,000 for the third quarter of 1997, as compared to $97,000 in the same
period of 1996 and increased to $1,039,000 for the nine months ended September
30, 1997, as compared to $102,000 in the same period of 1996. These increases
are attributable to the opening of new or acquired properties in 1996 and 1997.

Interest expense increased to $445,000 for the third quarter of 1997, as
compared to $169,000 for the same period in 1996 and increased to $1,325,000
for the nine months ended September 30, 1997, as compared to $190,000 for the
same period in 1996. This interest relates primarily to the loan on the Westar
hotels which was acquired by the Company on September 6, 1996. Interest on all
other loans has been capitalized as construction period interest for the
properties under development. The increases in interest expense are due to
there being a full three months of interest expense on the Westar hotels in the
third quarter of 1997 and a full nine months of interest expense on the Westar
hotels for the nine months ended September 30, 1997, as compared to twenty-five
days in the same periods of 1996.

The hotel in Grand Prairie, which began operations on June 17, 1996, was the
only hotel that the Company operated for the full three months ended September
30, 1996 and three months ended September 30, 1997. The occupancy rate for the
Grand Prairie hotel increased to 60% for the third quarter of 1997, as compared
to 49% for the same period in 1996. The Average Weekly Rate increased to
$234.78 for the third quarter of 1997, as compared to $207.91 for the same
period in 1996. The weekly REVPAR increased to $140.01 for the third quarter of
1997 as compared to $102.10 in the same period of 1996.

During the three months and nine months ended September 30, 1997, the Westar
hotels lost 14,496 and 35,610 room nights, respectively, due to rooms being
renovated. The Available Room Nights for the three months and nine months ended
September 30, 1997 were 56,602 and 169,184, respectively. This represented a
26% loss and 21% loss of potential revenue from these hotels during the three
months and nine months ended September 30,



                                                                             15

1997, respectively, with an additional loss of revenue due to guests not
wanting to be inconvenienced while the hotels are under construction.


CORPORATE OPERATIONS

Corporate operating expenses include all expenses related to the administration
of the corporate offices and all expenses not directly related to individual
developments and hotels. Corporate operating expenses increased to $533,000 for
the third quarter of 1997 as compared to $314,000 in the same period of 1996
and increased to $1,947,000 for the nine months ended September 30, 1997, as
compared to $519,000 in the same period in 1996. These increases are primarily
due to the increase in the number of employees and related expenses and
increased costs due to the Company being a publicly held entity.

LIQUIDITY AND CAPITAL RESOURCES

At September 30, 1997, the Company had cash and cash equivalents of $1,535,000.
Cash balances are currently invested in short-term, investment grade, interest
bearing securities.

The Company owes approximately $17.8 million on a 9.71% secured promissory note
for the purchase of the Westar hotels.  This debt is payable on a fixed 25-year
amortization schedule in monthly installments through January 11, 2021.

The Company owes approximately $1.9 million on a 7.97% secured promissory note
for the purchase of the 511 Queens corporate housing project in Charlotte,
North Carolina. This debt is payable on a fixed 10-year amortization schedule
in monthly installments through September 2007.

The Company has a $30 million mortgage loan facility (the "Existing Mortgage
Facility") with Bank One, Texas, N.A.  ("BOA"), which provides the Company with
construction financing for up to eight extended-stay hotels. The Company is
permitted to borrow under the Existing Mortgage Facility through November 30,
1997. Each project may be funded under the Existing Mortgage Facility through a
separate loan, with all loans being cross-collateralized and cross-defaulted.
Initially, such loans will be advanced as construction loans, payable over
twenty-four months (the "Construction Term") with interest at either the BOA
prime rate plus 0.5% or LIBOR plus 2.25%. The Company must make interest
payments on each construction loan for the first twelve months of the loan,
followed by principal and interest payments based on a fifteen-year
amortization schedule for the remaining twelve months of the loan. The Company
may elect to extend each loan for three additional years (the "Mini-perm Term")
if certain conditions are met and upon payment of a specified extension fee. If
the Company elects to extend the loan as a mini-permanent financing, the
Company will be obligated to make principal and interest payments on a
fifteen-year amortization schedule during each year of the three-year extension
period, and the interest rate may, in certain circumstances, be reduced. During
the Construction Term, the amount of any loan may not exceed 55% of the total
project costs of the related project. During the Mini-perm Term, the loan
amount to costs-of-project ratio may be increased to 65% if certain conditions
are met. BOA will have full recourse against the Company for the loans,
including environmental indemnities.

As of September 30, 1997, the Company had incurred indebtedness under the
Existing Mortgage Facility of approximately $16.3 million of which $4.8 million
was attributed to the Town Lake hotel in Austin, $2.8 million was attributed to
the Studio Suites hotel in Grand Prairie, $3.2 million was attributed to the
44th and Oak hotel in Phoenix, $2.5 million was attributed to the Denver Tech
Center hotel in Denver, $1.1 million was attributed to the Park Central hotel
in Dallas, and $1.9 million was attributed to the I-10 and Chandler hotel in
Phoenix . The Austin Town Lake hotel and Grand Prairie hotel loans bear
interest at LIBOR plus 2.25% and the remaining four loans bears interest at
LIBOR plus 2.5%. The Austin debt is due on February 4, 2000 and the Grand
Prairie debt is due on May 31, 1999. The Phoenix 44th and Oak debt is due on
August 15, 1998, the Denver Tech Center debt is due on July 21, 1999, the
Phoenix I-10 and Chandler debt is due on August 6, 1999, the Dallas Park
Central debt is due on August 18, 1999; however, these loans may be extended
for an additional three years as described above.

On July 25, 1997, the Company entered into a definitive merger agreement
("Merger Agreement") with Prime Hospitality Corp. ("Prime") pursuant to which
the Company will merge with a wholly owned subsidiary of Prime. Under the
Merger Agreement, Prime will issue 0.6073 shares of its common stock for each
of the 10,725,000 outstanding shares of the Company's common stock. In
connection with the Merger Agreement, the Company and Prime executed a loan
agreement pursuant to which Prime agreed to provide a $65 million interim
secured construction term loan facility ("Construction Term Loan Facility") to
the Company. As of September 30, 1997, the outstanding balance on the
Construction Term Loan Facility was $23.9 million leaving a balance of $41.1



                                                                             17

million to be drawn, if necessary. The Construction Term Loan Facility is to be
used for the acquisition and hotel development of specific sites. The
Construction Term Loan Facility matures and all amounts outstanding thereunder
are due at the earlier of (a) April 1, 1998, (b) the date on which the Company
enters into any agreement (other than the Merger Agreement) with respect to any
alternative proposal or otherwise relating to the merger or sale of
substantially all of the assets of the Company and (c) four months after the
termination of the Merger Agreement. The Company paid a loan fee of 1% of the
aggregate principal amount of the Construction Term Loan Facility. Monthly
interest payments commence December 15, 1997. Interest accrues monthly at a
rate of the one month LIBOR plus 3.5%; provided that the interest rate will
increase to the one month LIBOR plus 5% on the date that is the earlier of (a)
November 30, 1997 and (b) the date of the termination of the Merger Agreement
(other than a termination as a result of a breach by Prime). The loans are
secured by a first priority perfected security interest in specified sites. The
amount of any loan under the facility may not exceed 75% of the total project
costs of the related project.

The Construction Term Loan Facility is secured by 23 properties currently under
development and by any future development properties. The amount of any
Construction Term Loan may not exceed 75% of the total project costs of the
related project. The loan documentation for the Construction Term Loan Facility
contains various affirmative and negative covenants concerning the operation of
the Company as well as events of default (including failure to pay amounts due
under the loan documents or to comply with such covenants or a breach of the
Merger Agreement by the Company). The loan documents require the Company to
comply with the covenants contained in the Merger Agreement.

Although the Company has access to financing under the Existing Mortgage
Facility and the Construction Term Loan Facility, the Company may need to
procure substantial additional financing over time to complete its Initial
Hotel Program, which calls for 65 hotels to be opened or under construction by
December 31, 1998. The exact amount of financing will depend upon a number of
factors including the number of properties the Company constructs or acquires
and the cash flow generated by its properties. The Company expects that it will
spend between $4 million and $9 million on each development or acquired hotel.

If the Merger is not consummated, the Company will face an immediate working
capital shortage that will require it to seek additional financing and take
measures to preserve cash. The Company would also be required to seek
replacement financing for the Construction Term Loan Facility, which will
mature on April 30, 1998. There can be no assurance that the required
additional financing would be available or that it would be available on
acceptable terms. Measures taken to preserve cash would most likely include the
interruption of construction activity on some or all projects under
development. Interruption of construction activity would preclude the Company
from meeting its growth plans, which would most likely have at least a
temporary material adverse effect on the market price of the Company's common
stock.

The Existing Mortgage Facility, Construction Term Loan Facility and any future
debt financings or issuances of preferred stock by the Company will be senior
to the rights of the holders of common stock, and any future issuances of
common stock will result in the dilution of the then-existing stockholders'
proportionate equity interests in the Company. In addition, future debt
facilities may materially limit the Company's ability to pay dividends.

In connection with the execution of the Merger Agreement, the Company, Prime,
Crow Hotel Realty Investors, L.P.  ("Crow"), and Wyndham Hotel Corporation and
certain of its affiliates (collectively, "Wyndham") entered into an Agreement
Regarding Termination of Management Agreements pursuant to which, upon
completion of the Merger, either the Company or Wyndham will have the right to
terminate all management agreements providing for Wyndham's management of the
Company's properties, thereby obligating the Company to pay to Wyndham $8
million and Crow to deliver to Wyndham a $4 million, six month, secured
promissory note, which



                                                                              18

payment and delivery will be in full satisfaction of any and all claims Wyndham
may have against the Company relating to termination of the management
agreements. On November 1, 1997, the Company transitioned the management of the
hotel properties from Wyndham to Prime.



                                                                              19

SEASONALITY

The lodging industry is seasonal in nature. Quarterly earnings may be adversely
affected by events beyond the Company's control, such as poor weather
conditions, economic factors and other considerations affecting travel. In
addition, occupancy rates and room revenues typically decline during the fourth
calendar quarter as business travel decreases during the holiday season. The
timing of openings of new properties could also lead to fluctuations in the
Company's quarterly earnings.

INFLATION

The rate of inflation as measured by changes in the consumer price index has
not had a material effect on the revenue or operating results of the Company.
There can be no assurance, however, that inflation will not affect future
operating or construction costs.

FACTORS AFFECTING FUTURE RESULTS OF OPERATIONS

The Company's future results of operations may be impacted by a number of
factors. Among such factors are local, regional and national economic
conditions, competition from other lodging properties, changes in real property
tax rates and in the availability, cost and terms of financing, the impact of
present or future environmental legislation and compliance with environmental
laws, the ongoing need for capital improvements, changes in operating expenses,
adverse changes in governmental rules and fiscal policies, civil unrest, acts
of God, including earthquakes and other natural disasters (which may result in
uninsured losses), acts of war and adverse changes in zoning laws.

SPECIAL NOTE ON FORWARD LOOKING STATEMENTS

This Report on Form 10-Q contains forward-looking statements within the meaning
of the Private Securities Litigation Reform Act of 1995. The forward looking
statement made in Item 2 with respect to the Company's expectation of
construction and developing 27 hotels by the end of 1998 is subject to the
risks of weather-induced construction delays.  The forward looking statements
made in Item 2 with regard to the Company's 11 sites with letters of intent,
contracts or other agreements to purchase and the other 11 sites under
evaluation are subject to the risks of the Company's ability to negotiate the
acquisition of and close on such sites (to the extent it has not already done
so) in a timely fashion, the risks associated with the various entitlements
processes, the risks of inclement weather and the risks associated with the
Company's ability to obtain the required capital (to the extent it has not
already done so). The forward looking statement made in Item 2 with reference
to the Company's expectation that the merger will occur promptly after the
December 1, 1997 stockholders meeting is subject to the risk that the Company's
stockholders could fail to approve the merger or that other conditions to the
merger could fail to be satisfied.
