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

INTRODUCTION

     We are one of the two leading owners and operators of fitness clubs in the
Northeast and Mid-Atlantic regions of the United States. As of March 31, 2000,
we operated 86 clubs that collectively served approximately 230,000 members. We
develop clusters of clubs to serve densely populated major metropolitan regions
in which a high percentage of the population commutes to work. We service such
populations by clustering clubs near the highest concentrations of its target
customers' areas of both employment and residence. Our target customer is
college-educated, typically between the ages of 20 and 44 and earns an annual
income of approximately $50,000.

     Our goal is to develop the premier health club network in each of the major
metropolitan regions we enter. We believe that clustering clubs allows us to
achieve strategic operating advantages that enhance our ability to achieve this
goal. In entering new regions, we develop these clusters by initially opening or
acquiring clubs located in the more central urban markets of the region and then
branching out from these urban centers to suburbs and ancillary communities.
Capitalizing on this clustering of clubs, as of March 31, 2000, approximately
half of our members participated in a membership plan that allows unlimited
access to all of our clubs for a higher membership fee.

     We have executed this strategy successfully in the New York region through
the network of clubs we operate under its New York Sports Club "NYSC" brand
name. We are the largest fitness club operator in Manhattan with 26 locations
and operate a total of 65 clubs under the NYSC name within a defined radius of
New York City. We operate 11 clubs surrounding Washington, DC under our
Washington Sports Club brand name and have begun establishing similar clusters
surrounding Boston and Philadelphia under our Boston Sports Club and
Philadelphia Sports Club brand names, respectively. The Company employs
localized brand names for its clubs to create an image and atmosphere consistent
with the local community, and to foster the recognition as a local network of
quality fitness clubs rather than a national chain.

     Our operating and selling expenses are comprised of both fixed and variable
costs. The fixed costs include salary expense, rent, utilities, janitorial
expenses and depreciation. Variable costs are primarily related to sales
commissions, advertising and supplies. As clubs mature and increase their
membership base, fixed costs are typically spread over an increasing revenue
base and operating margins tend to improve.

1999 and the quarter ended March 31, 2000.

  Three Months Ended March 31, 2000 Compared to Three Months Ended March 31,
1999

     Revenues.  Revenues increased approximately $13.1 million, or 36.3%, to
$49.3 million during the quarter ended March 31, 2000 from $36.1 million in the
quarter ended March 31, 1999. This increase resulted from the 27 clubs opened or
acquired the last three quarters of 1998 (approximately $3.0 million), 18 opened
or acquired during 1999 (approximately $5.1 million) and the three clubs
acquired in the first quarter of 2000 (approximately $1.3 million). In addition,
revenues increased during the quarter by approximately $3.7 million at the
Company's mature clubs (clubs owned and operated for at least 24 months)
resulting from increased membership and dues.

     Operating Expenses.  Operating expenses increased $11.2 million, or 33.5%,
to $44.6 million in the quarter ended March 31, 2000, from $33.4 million in the
quarter ended March 31, 1999. The increase was primarily due to a 22.6% increase
in total months of club operations (the aggregate number of full months of
operation during a given period for the clubs open at the end of such period) to
247 in the quarter ended March 31, 2000 from 202 in the quarter ended March 31,
1999, in addition to the following factors:

          Payroll and related increased by $6.0 million, or 43.7% to $19.8
     million in the quarter ended March 31, 2000, from $13.8 million in the
     quarter ended March 31, 1999. This increase was principally attributable to
     the acquisition or opening of 18 clubs in 1999 and one of the acquired
     clubs in the first quarter of 2000. Payroll and related as a percent of
     revenue increased from 38.2% to 40.2%. This increase is principally due to
     increases in private training payroll.

          Club operating increased by $2.8 million or 22.3% to $15.3 million in
     the quarter ended March 31, 2000, from $12.5 million in the quarter ended
     March 31, 1999. This increase is attributable to the acquisition or opening
     of 18 clubs in 1999 and one of the acquired clubs in the first quarter of
     2000.

          General and administrative increased by $961,000, or 42.5% to $3.2
     million in the quarter ended March 31, 2000, from $2.3 million, in the
     quarter ended March 31, 1999. This increase is attributable to expenses
     associated with the Company's expansion, including the expansion of the
     Company's corporate office and upgrade of the Company's management
     information systems. In March 1999 the Company

                                        7
<PAGE>   9

     moved its membership billing processing center to a purpose-built location
     separated from its corporate office.

          Depreciation and amortization increased by $1.4 million, or 30.2% to
     $6.0 million in the quarter ended March 31, 2000, from $4.6 million in the
     quarter ended March 31, 1999 This increase is attributable primarily to a
     full period of depreciation and amortization for fixed asset additions,
     acquisitions or club openings since the quarter ended March 31, 1999 and
     the increased fixed and intangible assets arising out of one of the club
     acquisitions during the first quarter of 2000.

          Compensation expense in connection with stock options increased
     $19,000 or 10.0% to $209,000 for the quarter ended March 31, 2000 from
     $190,000 in the quarter ended March 31, 1999 and relates to preferred stock
     options. The increase is attributable to the compounding of dividends on
     these preferred stock options.

     Interest Expense.  Interest expense increased $1.4 million to $3.6 million
during the quarter ended March 31, 2000, from $2.2 million in the quarter ended
March 31, 1999. This increase was primarily due to increased borrowings
associated with the completion of the $40 million Senior Note issuance in June
of 1999.

     Interest Income.  Interest income increased $306,000 to $556,000 during the
quarter ended March 31, 2000 from $250,000 in the quarter ended March 31, 1999.
The increased level of interest income was primarily due to higher levels of
cash on hand and slightly higher interest rates earned during the quarter ended
March 31, 2000.

     Provision for Income Tax.  The income tax provision for the quarter ended
March 31, 2000 was $784,000 compared to a tax provision of $395,000 for the
quarter ended March 31, 1999.

     Accreted Dividends on Preferred Stock.  Accreted dividends on the preferred
stock increased $237,000 to $2.2 million during the quarter ended March 31,
2000, from $1.9 million in the quarter ended March 31, 1999. This increase is
primarily a result of the compounding of accreted dividends previously recorded.

LIQUIDITY AND CAPITAL RESOURCES

     Historically, the Company has satisfied its liquidity needs through cash
from operations and various borrowing arrangements. Principal liquidity needs
have included the acquisition and development of new clubs, debt service
requirements and other capital expenditures necessary to maintain existing
clubs.

     Operating Activities.  Net cash provided by operating activities for the
quarter ended March 31, 2000 was $16.7 million compared to $10.5 million for the
quarter ended March 31, 1999, an increase of $6.2 million. Cash flows from
operations has improved as the profitability of the mature club base and the
clubs opened or acquired during the last three quarters of 1998, continues to
improve. The balance of the increase is principally due to an increase in the
working capital deficit of the Company. Excluding cash and cash equivalents, the
Company normally operates with a working capital deficit because it receives
dues or fee revenue either (I) during the month services are rendered, or (ii)
when paid-in-full, 12 months in advance. As a result, the Company has no
material accounts receivable. In addition, because initiation fees are received
at enrollment and are recognized over the estimated average term of membership,
the Company records a deferred revenue liability. Management believes that the
Company's working capital deficit is an important source of cash flow from
operating activities that it believes will continue to grow as the Company's
membership revenues increase.

     Investing Activities.  The Company invested $12.8 million and $5.1 million
in capital expenditures and business acquisitions, respectively during the
quarter ended March 31, 2000. The Company currently estimates total capital
expenditure and asset acquisition requirements for the remaining three quarters
of 2000 to approximate $33.0 million, which includes $2.1 million that
management intends to renovate and expand certain existing clubs, $5.2 million
to maintain certain existing clubs and $3.0 million to further upgrade its
management information systems.

     Financing Activities.  The Company has a line of credit with its principal
bank for direct borrowings and letters of credit of up to $25 million. The line
of credit contains restrictive covenants, including a leverage ratio and
interest coverage ratio and dividend payment restrictions and is collateralized
by all the assets of the

Company. As of March 31, 2000, the Company has approximately $23.4 million
available under the line of credit, which matures in October 2002, and has no
scheduled amortization requirements. The Credit Facility was amended to allow
for maximum borrowings or $25.0 million. Although management believes that the
Company will be able to obtain or generate sufficient funds to finance the
Company's current operating and growth plans through the end of 2000, any
material acceleration or expansion of that plan through additional greenfields
or acquisitions (to the extent such acquisitions include cash payments) may
require the Company to pursue additional sources of financing prior to the end
of 2000. There can be no assurance that such financing will be available or that
it will be available on acceptable terms. The inability to finance such further
or accelerated expansion on acceptable terms may negatively impact the Company's
competitive position and or materially adversely affect the Company's business,
results of operations or financial condition. The Credit Facility accrues
interest at variable rates based on market conditions, accordingly, future
increase in interest rates could have a negative impact on net income.
