ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS
 
     The following section contains forward-looking statements which involve
risks and uncertainties. Such forward-looking statements may be deemed to
include anticipated restaurant openings, anticipated costs and sizes of future
restaurants and the adequacy of anticipated sources of cash to fund the
Company's future capital requirements. Words such as "believes," "anticipates,"
"expects," "intends," "plans" and similar expressions are intended to identify
forward-looking statements, but are not the exclusive means of identifying such
statements. The Company's actual results may differ materially from those
discussed in the forward-looking statements. Factors that might cause actual
events or results to differ materially from those indicated by such
forward-looking statements may include matters noted elsewhere in this Form
10-Q, such as development and construction risks, potential labor shortages,
fluctuations in operating results, and changes in food costs.
 
OVERVIEW
 
     P.F. Chang's owns and operates 25 full service restaurants (as of March 28,
1999) that feature a distinctive blend of high quality, traditional Chinese
cuisine and American hospitality in a sophisticated, contemporary bistro
setting. The Company was formed in early 1996 with the acquisition of the four
original P.F. Chang's restaurants and the hiring of an experienced management
team, led by Richard Federico and Robert Vivian, the Company's Chief Executive
Officer and Chief Financial Officer, respectively, to support the Company's
founder, Paul Fleming. Utilizing a partnership management philosophy, the
Company embarked on a strategic expansion of the concept targeted at major
metropolitan areas throughout the United States and opened three additional
restaurants in 1996, six in 1997, and 10 in 1998.
 
     The Company intends to open thirteen new restaurants in 1999 (two of which
were open as of March 28, 1999). The 13 units that the Company intends to
develop in 1999 will be situated in approximately 8 new markets across the
United States. The Company has signed lease agreements for all of the 13 units
planned for 1999. The Company intends to continue to develop restaurants that
typically range in size from 6,000 square feet to 7,000 square feet, and that
require on average, a total cash investment of between $1.5 million and $2.0
million and a total capitalized investment of between $2.5 million and $3.0
million per restaurant. This total investment includes the capitalized lease
value of the property, which can vary greatly depending on the specific trade
area. See "Risk Factors -- Development and Construction Risks."
 
RESULTS OF OPERATIONS
 
     The following tables set forth certain unaudited quarterly information for
the three months ended March 29, 1998 and the three months ended March 28, 1999,
expressed as a percentage of revenues, except for revenues which are expressed
in thousands. This quarterly information has been prepared on a consistent basis
with the audited financial statements and, in the opinion of management,
includes all adjustments, consisting only of normal recurring adjustments,
necessary for a fair presentation of the information for the periods presented.
The Company's quarterly operating results may fluctuate significantly as a
result of a variety of factors, and operating results for any quarter are not
necessarily indicative of results for a full fiscal year.
 
     Historically, the Company has experienced variability in the amount and
percentage of revenues attributable to preopening expenses. The Company
typically incurs the most significant portion of preopening expenses associated
with a given restaurant within the two months immediately preceding and the
month of the opening of the restaurant. In addition, the Company's experience to
date has been that labor and operating costs associated with a newly opened
restaurant (for approximately its first four to six months of operation) are
materially greater than what can be expected after that time, both in aggregate
dollars and as a percentage of revenues. Accordingly, the volume and timing of
new restaurant openings has had and is expected to have a meaningful impact on
preopening expenses, labor and operating costs until such time as a larger base
of restaurants in operation mitigates such impact.

</TABLE>
 
THREE MONTHS ENDED MARCH 28, 1999 COMPARED TO THREE MONTHS ENDED MARCH 29, 1998
 
  Revenues
 
     The Company's revenues are derived entirely from food and beverage sales.
Revenues increased by $14.7 million, or 93.7%, to $30.5 million in the three
months ended March 28, 1999 from $15.7 million in the three months ended March
29, 1998. The increase was primarily attributable to revenues of $12.9 million
generated by new restaurants opened subsequent to March 29, 1998 and a $1.8
million increase in revenues in the three months ended March 28, 1999 for
existing restaurants. Increased customer visits produced comparable restaurant
sales gains of 11.0% in the three months ended March 28, 1999. The Company did
not implement any meaningful price increases in either period.
 
  Costs and expenses
 
     Cost of sales.  Cost of sales is composed of the cost of food and
beverages. Cost of sales decreased as a percentage of revenues to 27.5% in the
three months ended March 28, 1999 from 27.9% in the three months ended March 29,
1998. This decrease was primarily the result of cost efficiencies achieved
through the improved management of product purchasing, food preparation and
waitstaff performance as the Company's restaurants mature.
 
     Labor.  Labor expenses consist of restaurant management salaries, hourly
staff payroll costs and other payroll-related items. Labor expenses as a
percentage of revenues increased to 29.9% in the three months ended March 28,
1999 from 29.0% in the three months ended March 29, 1998. The increase in labor
expenses was primarily due to the fact that the Company opened eight new
restaurants during the six months ended March 28, 1999 compared to only four new
restaurants during the six months ended March 29, 1998. The Company's experience
to date has been that labor costs associated with a newly opened restaurant (for
approximately its first four to six months of operation) are materially greater
than what can be expected after that time, both in aggregate dollars and as a
percentage of revenues. Additionally, the increase in hourly wages mandated by
the federal government and the State of California contributed to the increase
in labor costs. The increases in labor noted above were partially offset by
improvements in the management of hourly staff levels in the Company's more
mature restaurants.
 
                                        8
<PAGE>   9
 
     Operating.  Operating expenses consist primarily of various
restaurant-level costs, which are generally variable and are expected to
fluctuate with revenues. In addition, the Company's experience to date has been
that operating costs associated with a newly opened restaurant (for
approximately its first four to six months of operation) are materially greater
than what can be expected after that time, both in aggregate dollars and as a
percentage of revenues. Operating expenses increased as a percentage of revenues
to 16.8% in the three months ended March 28, 1999 from 16.4% in the three months
ended March 29, 1998 primarily due to the fact that the Company opened eight new
restaurants during the six months ended March 28, 1999 compared to only four new
restaurants during the six months ended March 29, 1998.
 
     Occupancy.  Occupancy costs include both fixed and variable portions of
rent, common area maintenance charges, property insurance and property taxes.
Occupancy costs decreased nominally as a percentage of revenues to 6.9% in the
three months ended March 28, 1999 from 7.0% in the three months ended March 29,
1998.
 
     General and administrative.  General and administrative expenses are
composed of expenses associated with corporate and administrative functions that
support development and restaurant operations and provide an infrastructure to
support future growth, including management and staff salaries, employee
benefits, travel, legal and professional fees, technology and market research.
General and administrative expenses increased to $2.1 million (7.0% of revenues)
in the three months ended March 28, 1999 from $1.3 million (8.6% of revenues) in
the three months ended March 29, 1998. The increase was due primarily to the
addition of corporate management personnel which resulted in approximately
$390,000 of additional compensation and benefits expense as well as additional
costs to support a larger restaurant base, including an additional $100,000 in
travel and consulting fees. Also, the Company incurred additional costs during
the first quarter of 1999, such as printing, accounting, and legal costs, as a
result of becoming a public company in December of 1998. The decrease as a
percentage of revenues was due primarily to the Company's expanding revenue base
and its ability to leverage the duties and responsibilities of its Market
Partners (See "Elimination of minority interests" below).
 
     Depreciation and amortization.  Depreciation and amortization expenses
include the depreciation of fixed assets and the amortization of goodwill costs
associated with the acquisition of the ownership interests in the original
restaurants. Depreciation and amortization increased to $987,000 in the three
months ended March 28, 1999 from $489,000 in the three months ended March 29,
1998. This increase was primarily due to depreciation on new restaurants.
 
     Preopening.  Preopening costs, which are expensed as incurred, consist of
expenses incurred prior to opening a new restaurant and are comprised
principally of manager salaries and relocation, employee payroll and related
training costs. Preopening expenses in the three months ended March 28, 1999
increased to $715,000 from $432,000 in the three months ended March 29, 1998 due
to the greater number of restaurants opened or under development during the 1999
period.
 
     Interest income (expense), net.  Interest income increased to $218,000 in
the three months ended March 28, 1999 from an expense of $210,000 in the three
months ended March 29, 1998 principally due to the repayment of the Company's
revolving line of credit in December of 1998, and the subsequent investment of
cash from its initial public offering.
 
  Elimination of minority interests
 
     Elimination of minority interests represents the portion of the Company's
net earnings which are attributable to the collective ownership interests of its
partners. The Company has provided for a partnership management structure in
which it has entered into a series of partnership agreements with its regional
managers ("Market Partners"), certain of its general managers ("Operating
Partners") and certain of its executive chefs ("Culinary Partners"). Elimination
of minority interests increased to $417,000 for the three months ended March 28,
1999 from $156,000 for the three months ended March 29, 1998 due primarily to an
increase in the operating profit of the Company.
 
                                        9
<PAGE>   10
 
  Provision for income taxes
 
     The provision for income taxes for the three months ended March 28, 1999
increased to $491,000 from $4,000 for the three months ended March 29, 1999 due
primarily to the fact that the Company's taxable income increased substantially
from the prior period. The income tax provision for the three months ended March
28, 1999 differs from the expected provision for income taxes, derived by
applying the statutory income tax rate, as a result of the Company's expected
utilization in 1999 of its net operating loss carryforward and the resulting
decrease in the related deferred income tax valuation allowance.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     The Company has funded its capital requirements since its inception through
sales of equity securities, debt financing, sale-leaseback arrangements and cash
flows from operations. Net cash provided by operating activities was $4.4
million and $1.7 million for the three months ended March 28, 1999 and March 29,
1998, respectively. Net cash provided by operating activities exceeded the net
income for the periods due principally to the effect of depreciation and
amortization and reductions in receivables.
 
     The Company uses cash primarily to fund the development and construction of
new restaurants. Net cash used in investing activities in the three months ended
March 28, 1999 and March 29, 1998 was $5.7 million and $3.7 million,
respectively. Capital expenditures made up the majority of its investing
activities in both periods. The Company intends to open thirteen restaurants in
1999 (two of which were open as of March 28, 1999). The Company expects that its
planned future restaurants will require, on average, a total cash investment per
restaurant, exclusive of landlord contributions, of approximately $1.5 million
to $2.0 million. Preopening expenses are expected to average approximately
$300,000 per restaurant, however, any unexpected delays in construction, labor
shortages, or other factors could result in higher than anticipated preopening
costs.
 
     Net cash used in financing activities in the three months ended March 28,
1999 was $529,000 compared to net cash provided by financing activities in the
three months ended March 29, 1998 of $1.7 million. Financing activities in the
first quarter of 1999 consisted primarily of distributions to the Company's
partners and repayments of long term debt. Financing activities in the first
quarter of 1998 consisted principally of borrowings under the Company's credit
facility, which was paid in full at the time of the Company's initial public
offering and expired in December 1998.
 
     The Company's capital requirements, including development costs related to
the opening of additional restaurants, have been and will continue to be
significant. The Company's future capital requirements and the adequacy of its
available funds will depend on many factors, including the pace of expansion,
real estate markets, site locations and the nature of the arrangements
negotiated with landlords. Although no assurance can be given, the Company
believes that cash flow from operations together with its current cash reserves
will be sufficient to fund its capital requirements through 1999. In the event
that additional capital is required, the Company may seek to raise such capital
through public or private equity or debt financings. The Company is negotiating
to secure a line of credit facility to help fund its development beyond 1999.
Future capital funding transactions may result in dilution to current
shareholders. There can be no assurance that such capital will be available on
favorable terms, if at all.
 
RISK FACTORS
 
  Restaurant Industry and Competition
 
     The restaurant industry is intensely competitive with respect to food
quality, price-value relationships, ambiance, service and location, and many
restaurants compete with the Company at each of its locations. The Company's
competitors include mid-price, full-service casual dining restaurants and
locally owned and operated Chinese restaurants. There are many well-established
competitors with substantially greater financial, marketing, personnel and other
resources than the Company, and many of the Company's competitors are well
established in the markets where the Company's operations are, or in which they
may be, located. Additionally, other companies may develop restaurants that
operate with similar concepts.
 
     The restaurant business is often affected by changes in consumer tastes,
national, regional or local economic conditions, demographic trends, consumer
confidence in the economy, discretionary spending
                                       10
<PAGE>   11
 
priorities, weather conditions, tourist travel, traffic patterns and the type,
number and location of competing restaurants. Changes in these factors could
have a material adverse effect on the Company's business, financial condition,
results of operations or cash flows. In the future, changes in consumer tastes
may require the Company to modify or refine elements of its restaurant system to
evolve its concept in order to compete with popular new restaurant formats or
concepts that develop from time to time, and there can be no assurance that the
Company will be successful in implementing such modifications.
 
  Uncertainties Associated with Expanding Operations
 
     The Company operates 25 restaurants (as of March 28, 1999), twelve of which
have been opened within the last twelve months. The results achieved to date by
the Company's relatively small number of restaurants may not be indicative of
those restaurants' long-term performance or the potential market acceptance of
restaurants in other locations. Further, there can be no assurance that any new
restaurant which the Company opens will obtain similar operating results to
those of prior restaurants. The Company anticipates that its new restaurants
will commonly take several months to reach planned operating levels due to
certain inefficiencies typically associated with new restaurants, including lack
of market awareness, inability to hire sufficient staff and other factors.
 
     A critical factor in the Company's future success is its ability to
successfully expand its operations. The Company's ability to expand successfully
will depend on a number of factors, including the identification and
availability of suitable locations, competition for restaurant sites, the
negotiation of favorable lease arrangements, timely development in certain cases
of commercial, residential, street or highway construction near the Company's
restaurants, management of the costs of construction and development of new
restaurants, securing required governmental approvals and permits, recruitment
of qualified operating personnel (particularly managers and chefs), the
competition in new markets, general economic conditions and other factors, some
of which are beyond the control of the Company. The opening of additional
restaurants in the future will depend in part upon the Company's ability to
generate sufficient funds from operations or to obtain sufficient equity or debt
financing on favorable terms to support such expansion. There can be no
assurance that the Company will be successful in addressing these risks, that
the Company will be able to open its planned new operations on a timely basis,
if at all, or, if opened, that those operations will be operated profitably. The
Company has experienced, and expects to continue to experience, delays in
restaurant openings from time to time. Delays or failures in opening planned new
restaurants could have a material adverse effect on the Company's business,
financial condition, results of operations or cash flows.
 
     The Company's growth strategy may strain the Company's management,
financial and other resources. To manage its growth effectively, the Company
must maintain a high level of quality and service at its existing and future
restaurants, continue to enhance its operational, financial and management
capabilities and locate, hire, train and retain experienced and dedicated
operating personnel, particularly managers and chefs.
 
  Purchasing
 
     The Company's purchasing programs provide its restaurants with high quality
ingredients at competitive prices from reliable sources. Consistent menu
specifications as well as purchasing and receiving guidelines ensure freshness
and quality. Because the Company utilizes only fresh ingredients in all of its
menu offerings, inventory is maintained at a modest level. The Company
negotiates short-term and long-term contracts depending on demand for its
products. These contracts range in duration from two to twelve months. With the
exception of produce, which is purchased locally, the Company utilizes
Distributors Marketing Alliance as the primary distributor of product to all of
its restaurants. Distributors Marketing Alliance is a cooperative of multiple
food distributors located throughout the nation. The Company has a non-exclusive
short term contract with Distributors Marketing Alliance on terms and conditions
which the Company believes are consistent with those made available to similarly
situated restaurant companies. The Company believes that competitively priced
alternative distribution sources are available should such channels be
necessary. Chinese-specific ingredients are usually sourced directly from Hong
Kong, China and Taiwan. The Company has developed an extensive network of
importers in order to maintain an adequate supply of items that conform to the
Company's brand and product specifications.
 
                                       11
<PAGE>   12
 
  Inflation
 
     The primary inflationary factors affecting the Company's operations are
food and labor costs. A large number of the Company's restaurant personnel are
paid at rates based on the applicable minimum wage, and increases in the minimum
wage directly affect the Company's labor costs. To date, inflation has not had a
material impact on the Company's results of operations.
 
  Development and Construction Risks
 
     Because each P.F. Chang's restaurant is distinctively designed to
accommodate particular characteristics of each location and to blend local or
regional design themes with the Company's principal trade dress and other common
design elements, each location presents its own development and construction
risks. Many factors may affect the costs associated with the development and
construction of the Company's restaurants, including labor disputes, shortages
of materials and skilled labor, weather interference, unforeseen engineering
problems, environmental problems, construction or zoning problems, local
government regulations, modifications in design to the size and scope of the
projects and other unanticipated increases in costs, any of which could give
rise to delays or cost overruns. There can be no assurance that the Company will
be able to develop additional P.F. Chang's restaurants within anticipated
budgets or time periods, and any such failure could materially adversely affect
the Company's business, financial condition, results of operations or cash
flows.
 
  Dependence on Key Personnel
 
     The success of the Company's business will continue to be highly dependent
on its key operating officers and employees, including Richard Federico, the
Company's Chief Executive Officer and President, Robert Vivian, the Company's
Chief Financial Officer, Greg Carey, the Company's Chief Operating Officer, and
Frank Ziska, the Company's Chief Development Officer. The Company's success in
the future will be dependent on its ability to attract, retain and motivate a
sufficient number of qualified management and operating personnel, including
Market Partners, Operating Partners and Culinary Partners, to keep pace with an
aggressive expansion schedule. Such qualified individuals are historically in
short supply and any inability of the Company to attract and retain such key
employees may limit its ability to effectively penetrate new market areas.
Additionally, the ability of these key personnel to maintain consistency in the
quality and atmosphere of the Company's restaurants in various markets is a
critical factor in the Company's success. Any failure to do so may harm the
Company's reputation and could have a material adverse effect on the Company's
business, financial condition, results of operations or cash flows.
 
  Governmental Regulation
 
     The Company's restaurants are subject to regulation by federal agencies and
to licensing and regulation by state and local health, sanitation, building,
zoning safety, fire and other departments relating to the developmental and
operation of restaurants. These regulations include matters relating to
environmental, building construction, zoning requirements and the preparation
and sale of food and alcoholic beverages. The Company's facilities are licensed
and subject to regulation under state and local fire, health and safety codes.
 
     The development and construction of additional restaurants will be subject
to compliance with applicable zoning, land use and environmental regulations.
There can be no assurance that the Company will be able to obtain necessary
licenses or other approvals on a cost-effective and timely basis in order to
construct and develop restaurants in the future. Various federal and state labor
laws govern the Company's operations and its relationship with its employees,
including minimum wage, overtime, working conditions, fringe benefit and
citizenship requirements. In particular, the Company is subject to the
regulations of the INS. Given the location of many of the Company's restaurants,
even if the Company's operation of those restaurants is in strict compliance
with INS requirements, the Company's employees may not all meet federal
citizenship or residency requirements, which could lead to disruptions in its
work force.
 
     Approximately 20% of the Company's revenues are attributable to the sale of
alcoholic beverages. The Company is required to comply with the alcohol
licensing requirements of the federal government, states and municipalities
where its restaurants are located. Alcoholic beverage control regulations
require applications to
 
                                       12
<PAGE>   13
 
state authorities and, in certain locations, county and municipal authorities
for a license and permit to sell alcoholic beverages. Typically, licenses must
be renewed annually and may be revoked or suspended for cause at any time.
Alcoholic beverage control regulations relate to numerous aspects of the daily
operations of the restaurants, including minimum age of guests and employees,
hours of operation, advertising, wholesale purchasing, inventory control and
handling, storage and dispensing of alcoholic beverages. Failure to comply with
federal, state or local regulations could cause the Company's licenses to be
revoked or force it to terminate the sale of alcoholic beverages at one or more
of its restaurants.
 
     The Company is subject to state "dram shop" laws and regulations, which
generally provide that a person injured by an intoxicated person may seek to
recover damages from an establishment that wrongfully served alcoholic beverages
to such person. While the Company carries liquor liability coverage as part of
its existing comprehensive general liability insurance, there can be no
assurance that it will not be subject to a judgment in excess of such insurance
coverage or that it will be able to obtain or continue to maintain such
insurance coverage at reasonable costs, or at all.
 
     The federal Americans With Disabilities Act prohibits discrimination on the
basis of disability in public accommodations and employment. The Company is
required to comply with the Americans With Disabilities Act and regulations
relating to accommodating the needs of the disabled in connection with the
construction of new facilities and with significant renovations of existing
facilities.
 
  Minimum Wage
 
     A number of the Company's employees are subject to various minimum wage
requirements. Many of the Company's employees work in restaurants located in
California and receive salaries equal to the California minimum wage. The
minimum wage in California rose from $5.00 per hour effective March 1, 1997 to
$5.75 per hour effective March 1, 1998. There can be no assurance that similar
increases will not be implemented in other jurisdictions in which the Company
operates or seeks to operate. In addition, the federal minimum wage increased to
$5.15 per hour effective September 1, 1997. There can be no assurance that the
Company will be able to pass additional increases in labor costs through to its
guests in the form of menu price adjustments and accordingly, such minimum wage
increases could have a material adverse effect on the Company's business,
financial condition, results of operations or cash flows.
 
  Potential Labor Shortages
 
     The success of the Company will continue to be dependent on its ability to
attract and retain a sufficient number of qualified employees, including kitchen
staff and waitstaff, to keep pace with its expansion schedule. Qualified
individuals needed to fill these positions are in short supply in certain areas,
and the inability to recruit and retain such individuals may delay the planned
openings of new restaurants or result in high employee turnover in existing
restaurants which could have a material adverse effect on the Company's
business, financial condition, cash flows or results of operations.
 
  Fluctuations in Operating Results
 
     The Company's operating results may fluctuate significantly as a result of
a variety of factors, including general economic conditions, consumer confidence
in the economy, changes in consumer preferences, competitive factors, weather
conditions, the timing of new restaurant openings and related expenses, revenues
contributed by new restaurants and increases or decreases in comparable
restaurant revenues. Historically, the Company has experienced variability in
the amount and percentage of revenues attributable to preopening expenses. The
Company typically incurs the most significant portion of preopening expenses
associated with a given restaurant within the two months immediately preceding
and the month of the opening of the restaurant. In addition, the Company's
experience to date has been that labor and operating costs associated with a
newly opened restaurant for the first several months of operation are materially
greater than what can be expected after that time, both in aggregate dollars and
as a percentage of revenues. Accordingly, the volume and timing of new
restaurant openings has had and is expected to have a meaningful impact on
preopening expenses and labor and operating costs until such time as a larger
base of restaurants in operation mitigates such impact. Due to the foregoing
factors, results for any one quarter are not necessarily indicative of results
to be expected for any other quarter or for a full fiscal year, and, from time
to time in the future, the Company's results of
 
                                       13
<PAGE>   14
 
operations may be below the expectations of public market analysts and
investors. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations."
 
  Changes in Food Costs
 
     The Company's profitability is dependent in part on its ability to
anticipate and react to changes in food costs. Other than for produce, which is
purchased locally by each restaurant, the Company relies on Distributors
Marketing Alliance as the primary distributor of its food. Distributors
Marketing Alliance is a cooperative of multiple food distributors located
throughout the nation. The Company has a non-exclusive short term contract with
Distributors Marketing Alliance on terms and conditions which the Company
believes are consistent with those made available to similarly situated
restaurant companies. Although the Company believes that alternative
distribution sources are available, any increase in distribution prices or
failure to perform by the Distributors Marketing Alliance could cause the
Company's food costs to fluctuate. Further, various factors beyond the Company's
control, including adverse weather conditions and governmental regulation, may
affect the Company's food costs. There can be no assurance that the Company will
be able to anticipate and react to changing food costs through its purchasing
practices and menu price adjustments in the future, and failure to do so could
have a inaterial adverse effect on the Company's business, financial condition,
results of operations or cash flows.
 
  Year 2000 Compliance
 
     The Company is aware of the issues associated with the programming code in
existing computer systems as the year 2000 approaches. The "year 2000 problem"
is pervasive and complex as virtually every computer operation will be affected
in some way by the rollover of the two digit year value to "00". The issue is
whether computer systems will properly recognize date-sensitive information when
the year changes to 2000. Systems that do not properly recognize such
information could generate erroneous data or cause a system to fail. The Company
has reviewed both its information technology and its non-information technology
systems to determine whether they are year 2000 compliant, and the Company has
not identified any material systems which are not year 2000 compliant. The
Company has initiated formal communications with all significant suppliers and
service providers to determine the extent to which the Company is vulnerable to
those third parties' failure to remediate the year 2000 problem. The Company has
received written assurances of year 2000 compliance from a majority of the third
parties with whom it has relationships, including its POS, payroll and credit
card service providers. Unless public suppliers of water, electricity and
natural gas are disrupted for a substantial period of time (in which case the
Company's business may be materially adversely affected), the Company believes
its operations will not be significantly disrupted even if third parties with
whom the Company has relationships are not year 2000 compliant. Further, the
Company believes that it will not be required to make any material expenditure
to address the year 2000 problem. However, uncertainty exists concerning the
potential costs and effects associated with any year 2000 compliance, and the
Company intends to continue to make efforts to ensure that third parties with
whom it has relationships are year 2000 compliant.
 
  Litigation
 
     The Company is from time to time the subject of complaints or litigation
from guests alleging illness, injury or other food quality, health or
operational concerns. Adverse publicity resulting from such allegations may
materially adversely affect the Company and its restaurants, regardless of
whether such allegations are valid or whether the Company is liable. The Company
also is the subject of complaints or allegations from former or prospective
employees from time to time. A lawsuit or claim could result in an adverse
decision against the Company that could materially adversely affect the Company
or its business.
 
ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISKS
 
     Management believes that the market risk associated with the Company's
market risk sensitive instruments as of March 28, 1999 is not material, and
therefore, disclosure is not required.

ITEM 1.  LEGAL PROCEEDINGS
 
     The Company was not involved in any material legal proceedings as of March
28, 1999.
 
ITEM 2.  CHANGES IN SECURITIES AND USE OF PROCEEDS
 
     The Company registered and sold 3,922,500 shares of Common Stock, par value
$0.001 (the "Shares") on registration statement No. 333-59749 at an aggregate
offering price of $47,070,000 (or $12.00 per share), which was declared
effective on December 4, 1998 (the "Offering").
 
     The co-managing underwriters of the Offering were Donaldson, Lufkin &
Jenrette, NationsBanc Montgomery Securities LLC, and Dain Rauscher Wessels.
 
     Through March 28, 1999, the Company incurred the following expenses in
connection with the Offering:
 
<TABLE>

Underwriting discounts and commissions......................  $3,294,900
Other expenses (audit, legal, etc.).........................   1,100,000
                                                              ----------
  Total expenses............................................  $4,394,900
                                                              ==========
</TABLE>
 
     The net offering proceeds to the Company after deducting the total expenses
above were $42,675,100.
 
     The Company's use of proceeds through March 28, 1999 conformed to the
intended use of proceeds described in the Company's prospectus related to the
Offering. The Company's intended use of proceeds as stated in its prospectus was
the repayment of all amounts outstanding under its revolving line of credit as
well as the development of new restaurants in 1999 and for general corporate
purposes. In December 1998, the Company used $25,000,000 of its net proceeds to
repay the entire balance outstanding under its revolving line of credit, which
has now expired. Additionally, the Company used a portion of the net proceeds
through March 1999 for the construction of its two new restaurants opened during
the first quarter of 1999 and for the development of its other restaurants
currently under construction, as well as for general corporate purposes. The
Company intends to use the balance of the proceeds for the development of its
additional restaurants to be opened in 1999 and for general corporate purposes.
