                      STAFF LEASING, INC. AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                (in thousands, except share and per share data)

1.   GENERAL:

     The accompanying unaudited consolidated financial statements of Staff
Leasing, Inc.  (the "Company") have been prepared in accordance with generally
accepted accounting principles for interim financial information and with the
instructions to Form 10-Q.  These financial statements should be read in
conjunction with the audited consolidated financial statements and notes
thereto for the year ended December 31, 1996 included in the Company's
Registration Statement on Form S-1 (File No. 333-22933), as amended.  The
financial information furnished reflects all adjustments, consisting only of
normal recurring accruals, which are, in the opinion of management, necessary
for a fair presentation of the financial position, results of operations and of
cash flows for the interim periods presented.

     The Company's operations are currently conducted through Staff Capital,
L.P. (the "Partnership") and a number of subsidiary limited partnerships (the
"OLPs"). The consolidated operations of the Company exclude intercompany
accounts and transactions. Certain reclassifications have been made to the
consolidated financial statements of prior periods to conform to the current
period presentation.

2.   REORGANIZATION AND INITIAL PUBLIC OFFERING:

     Effective July 1, 1997, a reorganization (the "Reorganization") was
consummated whereby the Company became the sole limited partner of the
Partnership. Staff Acquisition, Inc. ("Staff Acquisition") is the sole general
partner of the Partnership and each of the OLPs.  The general partnership
interest of Staff Acquisition in the Partnership and in each of the OLPs is a
1% interest (for an aggregate ownership of 1.99% of the consolidated group).
Pursuant to the Reorganization all of the holders of the common limited
partnership interests in the Partnership exchanged their partnership interests
for 17,122,205 shares of common stock, certain of the preferred limited
partnership interests were exchanged for 2,074,267 shares of common stock and
warrants to purchase an aggregate of 1,352,253 shares of common stock with an
exercise price of $7.24 per share.  This transaction was accounted for as a
purchase among entities in common control and accordingly, for financial
statement presentation purposes, the Reorganization is being treated as a
pooling of interests of the Company and the Partnership as of and for the
periods presented.

     Additionally, in conjunction with the Reorganization, on July 1, 1997, the
Company completed an initial public offering (the "IPO") of 3,500,000 of its
$.01 par value common stock.  The Company subsequently issued an additional
444,978 shares resulting from the exercise of certain overallotment provisions
for a total issuance of 3,944,978 shares.  Net proceeds raised from the IPO,
including overallotment, amounted to approximately $61,070.  The proceeds from
the IPO were used to repay outstanding redeemable preferred partnership
interests of $16,294, including accrued fixed return of $2,552 and to repay
outstanding long-term debt of $15,200. The remainder will be used for general
corporate purposes.

     Had the IPO occurred on June 30, 1997 pro forma consolidated assets would
have been $110,973, which includes the write-off of unamortized debt issuance
costs and organization costs of $714 and $163, respectively.  Such costs will
be recorded in the Company's third quarter.  Pro forma consolidated liabilities
would have been $80,260 and consolidated shareholders' equity would have been
$30,713, which includes the write-off of $962 in unamortized accretion
associated with the original issuance of preferred limited partnership
interests. The write-off of such accretion will be recorded in the Company's
third quarter. Had the IPO been consummated as of the beginning of the
respective periods, on a pro forma basis, net income (loss) and net income 
(loss) per share attributable to common shareholders would have been $(2,438) 
or $(.10) per share and $6,778 or $.28 per share for the year ended December 
31, 1996 and six months ended 


                                 Page 7 of 18
<PAGE>   8
June 30, 1997, respectively.  Pro forma net income (loss) per share 
attributable to common shareholders is based upon pro forma weighted shares 
outstanding of 23,917,996.

3.  RESTRICTED CASH:

     The Company had cash deposits at June 30, 1997 of $3,500 that serve as
collateral on certain standby letters of credit issued in connection with the
Company's health benefit plan.  These cash deposits have been classified as
restricted cash in the accompanying consolidated balance sheets.

4.  PROPERTY AND EQUIPMENT:

Property and equipment consist of the following:

</TABLE>

The Company used a portion of the net proceeds of its IPO to repay the balance
of the bank credit facility on July 1, 1997.

6. EARNINGS PER SHARE:

     Net income (loss) per common share attributable to common shareholders has
been computed based on the weighted average number of shares of common stock
and common stock equivalents outstanding during each of the periods presented
using the treasury stock method. Pursuant to the rules of the Securities and
Exchange Commission, all warrants granted at prices less than the IPO price
during the twelve months preceding the IPO date have been included as common 
stock equivalents in the calculation of weighted shares outstanding for the 
periods presented.  The number of common stock equivalents included in weighted
shares outstanding were 776,546 and relate to the warrants issued in 
connection with the Reorganization.

     The Company will adopt Statement of Financial Accounting Standards No. 128
("FAS 128") in the fourth quarter of 1997, as required.  The Company will
continue to apply Accounting Principles Board Opinion 

                                 Page 8 of 18
<PAGE>   9
No. 15, "Earnings Per Share" until the adoption of FAS 128.  The pro forma 
earnings (loss) per share ("EPS") attributable to common shareholders computed 
under the provisions of FAS 128 for the three-months and six-months ended June 
30, 1997 are as follows: Basic EPS of $.22 and $.32, respectively, and diluted 
EPS of $.21 and $.31, respectively.  Pro forma basic and diluted EPS 
attributable to common shareholders for the three-months and six-months ended
June 30, 1996 are as follows: Basic EPS of $(.05) and $(.14), respectively, and
diluted EPS of $(.05) and $(.14), respectively.

7. INCOME TAXES:

     For the periods presented, the Company operated as a limited partnership
for Federal and state income tax purposes.  Accordingly, all earnings or losses
were passed directly to the partners and no provision for income taxes was
required.  Following the Reorganization, the Company will continue to be
operated through the Partnership and the OLPs, and, for Federal and state
income tax purposes, future taxable income generated by the Partnership will be
allocated to Staff Acquisition and not to the Company until Staff Acquisition
has been allocated income equal to certain net losses previously allocated to
it, in accordance with the Partnership agreement and applicable tax rules and
regulations.  As of December 31, 1996, the amount of such net losses was
approximately $12.9 million.  Additionally, the Company will have deductible
temporary differences which could be utilized to offset future taxable income.
Such deductible temporary differences amounted to approximately  $19.1 million
at December 31, 1996 and relate primarily to assets with tax basis in excess of
book basis and certain reserves which will be deductible in future periods.  As
a result of the IPO, the Company generated additional deductible temporary
differences of approximately $21 million which can also be utilized to offset
future taxable income.


8. COMMITMENTS AND CONTINGENCIES:

     The Company's employer and health care operations are subject to numerous
federal, state and local laws related to employment, taxes and benefit plan
matters.  Generally, these regulations affect all companies in the United
States. However, the regulatory environment for professional employer
organizations ("PEOs") is an evolving area due to uncertainties resulting from
the non-traditional employment relationships.  Many federal and state laws
relating to tax and employment matters were enacted prior to the development of
PEOs and do not specifically address the obligations and responsibilities of
these co-employer relationships.  If the IRS concludes that PEOs, are not
"employers" of certain worksite employees for purposes of the Internal Revenue
Code of 1986, as amended (the "Code"), the tax qualified status of the
Company's 401 (k) retirement plan as in effect prior to April 1, 1997 could be
revoked, its cafeteria plan may lose its favorable tax status and the Company
may no longer be able to assume the clients' Federal employment tax withholding
obligations. Any adverse developments in the above noted areas could have a
material effect on the Company's financial condition and future results of
operations.

        As disclosed in the Company's Form S-1 filing, dated June 25, 1997, as
amended, a complaint was filed by Taylor Bean & Whittaker Ltd., et al naming
the Company as defendant.  On July 31, 1997, the plaintiffs voluntarily
dismissed this action without prejudice.  The Company is party to certain other
pending claims which have arisen in the normal course of business, none of
which, in the opinion of management, are expected to have a material adverse
effect on the consolidated financial position or results of operations if
adversely resolved.

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS
         (dollar amounts in thousands, except share and per share data)

Overview

     The Company is the largest PEO ("Professional Employers Organization") in
the United States. At June 30, 1997, the Company served over 8,500 clients with
over 98,600 worksite employees. With 35 branches located in Florida, Texas,
Georgia and Arizona, the Company provides a broad range of services, including
payroll administration, risk management, benefits administration, unemployment
services and other human resource management services.  The Company's
operations are currently conducted through Staff Capital, L.P. (the
"Partnership") and a number of operating limited partnerships ("OLPs").

     Effective July 1, 1997, a reorganization (the "Reorganization") was
consummated whereby the Company became the sole limited partner of the
Partnership.  Staff Acquisition, Inc. ("Staff Acquisition") is the sole general
partner of the Partnership and each of the OLPs.  The general partnership
interest of Staff Acquisition in the Partnership and in each of the OLPs is a
1% interest (for an aggregate ownership of 1.99% of the consolidated group).
Pursuant to the Reorganization all of the holders of the common limited
partnership interests in the Partnership exchanged their partnership interests
for 17,122,205 shares of common stock, certain of the preferred limited
partnership interests were exchanged for 2,074,267 shares of common stock and
warrants to purchase an aggregate of 1,352,253 shares of common stock with an
exercise price of $7.24 per share.  This transaction was accounted for as a
purchase among entities in common control and accordingly, for financial
statement presentation purposes, the Reorganization is being treated as a
pooling of interests of the Company and the Partnership as of and for the
periods presented.

     Additionally, in conjunction with the Reorganization, on July 1, 1997, the
Company completed an initial public offering (the "IPO") of 3,500,000 of its
$.01 par value common stock.  The Company subsequently issued an additional
444,978 shares resulting from the exercise of certain overallotment provisions
for a total issuance of 3,944,978 shares.  Net proceeds raised from the IPO,
including overallotment, amounted to approximately $61,070.  The proceeds from
the IPO were used to repay outstanding redeemable preferred partnership
interests of $16,294, including accrued fixed return of $2,552 and to repay
outstanding long-term debt of $15,200. The remainder will be used for general
corporate purposes.

     Had the IPO occurred on June 30, 1997 pro forma consolidated assets would
have been $110,973, which includes the write-off of unamortized debt issuance
costs and organization costs of $714 and $163, respectively.  Such costs will
be recorded in the Company's third quarter.  Pro forma consolidated liabilities
would have been $80,260 and consolidated shareholders' equity would have been
$30,713, which includes the write-off of $962 in unamortized accretion
associated with the original issuance of preferred limited partnership
interests. The write-off of such accretion will be recorded in the Company's
third quarter. Had the IPO been consummated as of the beginning of the
respective periods, on a pro forma basis, net income (loss) and net income
(loss) per share attributable to common shareholders would have been $(2,438)
or $(.10) per share and $6,778 or $.28 per share for the year ended December
31, 1996 and six months ended June 30, 1997, respectively.  Pro forma net
income (loss) per share attributable to common shareholders is based upon pro
forma weighted shares outstanding of 23,917,996.

     Revenues consist of charges by the Company for the salaries and wages of
the worksite employees (including the employee-paid portion of health and other
benefits), the service fee and the clients' portion of health and retirement
benefits provided to the worksite employees. These charges are invoiced to the
client at the time of each periodic payroll. The service fee covers the cost of
certain employment-related taxes, workers' compensation insurance coverage and 
administrative and field services provided by the Company to the client, 
including payroll administration and safety, human resource 


                                Page 10 of 18
<PAGE>   11
and regulatory compliance consultation. Salaries and wages of worksite 
employees are affected by the inflationary effects on wage levels, including 
the effect of increases in the Federal minimum wage, and by competition in the 
labor markets in which the Company operates. Fluctuations in salaries and wages 
resulting from these factors have a proportionate impact on the Company's 
service fee, which is invoiced as a percentage of salaries and wages.

     Cost of services includes salaries and wages of worksite employees,
payroll taxes, employee benefit costs, workers' compensation insurance and
state unemployment taxes.

     Operating expenses consist primarily of salaries, wages and commissions
associated with the Company's internal employees, and general and
administrative expenses. Over the past several years, the Company has
experienced an increase in its operating expenses as the Company has expanded
its senior management, sales and marketing staff, payroll processing operations
and client and worksite employee service functions. The Company expects that
future revenue growth will result in increasing net income margins, as the
Company's fixed operating expenses are leveraged over a larger revenue base.

     For the periods presented, the Company operated as a limited partnership
for Federal and state income tax purposes. Accordingly, all earnings or losses
were passed directly to the partners and no provision for income taxes was
required. Following the Reorganization, the Company will continue to be
operated through the Partnership and the OLPs, and, for Federal and state
income tax purposes, future taxable income generated by the Partnership and
OLPs will be allocated to Staff Acquisition and not to the Company until Staff
Acquisition has been allocated income equal to certain net losses previously
allocated to it, in accordance with the Partnership agreement and applicable
tax rules and regulations. As of December 31, 1996, the amount of such net
losses was approximately $12.9 million. Additionally, the Company will have
deductible temporary differences which could be utilized to offset future
taxable income. Such deductible temporary differences amounted to approximately
$19.1 million at December 31, 1996 and relate primarily to assets with tax
basis in excess of book basis and certain reserves which will be deductible in
future periods. As a result of the IPO, the Company generated additional
deductible temporary differences of approximately $21 million which can also be
utilized to offset future taxable income.

     Profitability is largely dependent upon the Company's success in managing
revenues and costs that are within its control. These controllable revenues and
costs primarily relate to workers' compensation, health benefits and state
unemployment taxes. The Company manages these controllable costs through its
use of: (i) its guaranteed workers' compensation cost arrangement with Liberty
Mutual Insurance Company; (ii) appropriately designed health benefit plans that
encourage worksite employee participation, high managed care utilization and
efficient risk pooling; and (iii) aggressive management of its state
unemployment tax exposure.

Three Months Ended June 30, 1997 Compared to Three Months Ended June 30, 1996

     Revenues were $448.1 million for the three months ended June 30, 1997
compared to $350.5 million for the three months ended June 30, 1996,
representing an increase of $97.6 million, or 27.8%. This increase was due
primarily to an increased number of clients and worksite employees. From June
30, 1996 to June 30, 1997, the number of clients increased 23.2%, from 6,967 to
8,582, and the number of worksite employees increased 22.4%, from 80,596 to
98,622. The increase in the number of clients was the result of continuing
sales and marketing efforts in existing markets as well as the development of
new markets. Continued growth in revenues is primarily dependent upon
increasing the number of new clients, as well as limiting the attrition of the
current client base. The client referral program with Barnett Bank, which
accounted for approximately 500 new clients during the ten months ended 
June 30, 1997, terminated June 30, 1997.

     Cost of services were $425.5 million for the three months ended June 30,
1997 compared to $335.6 million for the three months ended June 30, 1996,
representing an increase of $89.9 million, or 26.8%.

     Salaries, wages and payroll taxes of worksite employees were $405.3
million for the three months ended June 30, 1997, compared to $313.7 million
for the three months ended June 30, 1996, representing an increase of $91.6
million, or 29.2%. The increase was larger than the increase in the number of
worksite employees on a percentage basis from the comparable period, due at
least in part to the effect of wage inflation.

     Benefits, workers' compensation, state unemployment taxes and other costs
were $20.2 million for the three months ended June 30, 1997, compared to $21.9
million for the three months ended June 30, 1996, representing a decrease of 
($1.7) million, or (7.8%). This decrease was due primarily to: (i) a 26.8% 
reduction in the workers' compensation expense rate; and (ii) the 
implementation of the Company's comprehensive health benefits action 



                                Page 12 of 18
<PAGE>   13
plan, leading to a reduction in the health benefit plan subsidy, from $2.5 
million for the three months ended June 30, 1996 to zero for the three months 
ended June 30, 1997.

     Gross profit was $22.6 million for the three months ended June 30, 1997,
compared to $14.9 million for the three months ended June 30, 1996,
representing an increase of $7.7 million, or 51.7%. The increase was due to the
reduction in benefits, workers' compensation, state unemployment taxes and
other costs as a percentage of revenues as described above.

     Operating expenses were $17.0 million for the three months ended June 30,
1997, compared to $14.4 million for the three months ended June 30, 1996,
representing an increase of $2.6 million, or 18.1%.

     Salaries, wages and commissions were $10.4 million for the three months
ended June 30, 1997, compared to $9.1 million for the three months ended June
30, 1996, representing an increase of $1.3 million, or 14.3%. This increase was
due primarily to: (i) $1.0 million of costs attributable to an increase in
corporate personnel hired to support the Company's expanded operations and
additional sales and sales support personnel located at its branch offices; and
(ii) $.3 million increase in sales commissions attributable to the growth in
the number of clients and worksite employees.

     Other general and administrative expenses were $5.5 million for the three
months ended June 30, 1997, compared to $4.5 million for the three months ended
June 30, 1996, representing an increase of $1.0 million, or 22.2%. This
increase was primarily a result of expanded sales and marketing programs for
1997. The balance of the increase was attributable to the growth in the number
of clients and worksite employees.

     Depreciation and amortization expenses increased by $0.3 million for the
three months ended June 30, 1997, compared to the three months ended June 30,
1996, representing an increase of 34.7%. This increase was primarily the result
of the Company's investment in management information systems hardware.
Amortization of capitalized software costs associated with the Company's
development of new payroll processing and management information systems began
July 1997, when the systems became operational. These costs will be amortized
over a seven-year period.

     Interest expense was $.6 million for the three months ended June 30, 1997,
compared to $.9 million for the three months ended June 30, 1996, representing
a decrease of $.3 million, or 33.3%. This decrease was primarily the result of
the reduction in the Company's long-term borrowings.

     Net income was $5.0 million for the three months ended June 30, 1997,
compared to a loss of ($0.5) million for the three months ended June 30, 1996,
representing an increase of $5.5 million, as a result of the factors discussed
above.

Six Months Ended June 30, 1997 Compared to Six Months Ended June 30, 1996

     Revenues were $850.5 million for the six months ended June 30, 1997
compared to $675.2 million for the six months ended June 30, 1996, representing
an increase of $175.3 million, or 26.0%. This increase was due primarily to an
increased number of clients and worksite employees. From June 30, 1996 to June
30, 1997, the number of clients increased 23.2%, from 6,967 to 8,582, and the
number of worksite employees increased 22.4%, from 80,596 to 98,622. The
increase in the number of clients was the result of continuing sales and
marketing efforts in existing markets as well as the development of new
markets. Continued growth in revenues is primarily dependent upon increasing
the number of new clients, as well as limiting the attrition of the current
client base.  In January 1997, the Company reduced the service fees charged on
average to its Florida clients in response to a reduction in workers' 
compensation rates in the State of Florida. While the Company believes this 
reduction in service fees has not adversely affected the Company's 
profitability to date because the Company has been able to offset the effect of 
this action by controlling expenses, it is possible that future service fee 
reductions could adversely affect the Company's operations.


                                Page 13 of 18

     Cost of services were $808.0 million for the six months ended June 30,
1997 compared to $647.0 million for the six months ended June 30, 1996,
representing an increase of $161.0 million, or 24.9%.

     Salaries, wages and payroll taxes of worksite employees were $768.1
million for the six months ended June 30, 1997, compared to $604.3 million for
the six months ended June 30, 1996, representing an increase of $163.8 million,
or 27.1%. The increase was slightly larger than the increase in the number of
worksite employees on a percentage basis from the comparable period, due at
least in part to the effect of wage inflation.

     Benefits, workers' compensation, state unemployment taxes and other costs
were $39.9 million for the six months ended June 30, 1997, compared to $42.7
million for the six months ended June 30, 1996, representing a decrease of $2.8
million, or 6.6%. This decrease was due primarily to: (i) a 26.8% reduction in
the workers' compensation expense rate commencing January 1, 1997; and (ii) the
implementation of the Company's comprehensive health benefits action plan,
leading to a reduction in the health benefit plan subsidy, from $5.0 million
for the six months ended June 30, 1996 to $1.0 million for the six months ended
June 30, 1997.

     Gross profit was $42.5 million for the six months ended June 30, 1997,
compared to $28.2 million for the six months ended June 30, 1996, representing
an increase of $14.3 million, or 50.8%. The increase was due to the reduction
in benefits, workers' compensation, state unemployment taxes and other costs as
a percentage of revenues as described above.

     Operating expenses were $33.4 million for the six months ended June 30,
1997, compared to $28.4 million for the six months ended June 30, 1996,
representing an increase of $5.0 million, or 17.6%.

     Salaries, wages and commissions were $20.7 million for the six months
ended June 30, 1997, compared to $18.1 million for the six months ended June
30, 1996, representing an increase of $2.6 million, or 14.4%. This increase was
due primarily to: (i) $1.9 million of costs attributable to an increase in
corporate personnel hired to support the Company's expanded operations and
additional sales and sales support personnel located at its branch offices; and
(ii) $.7 million increase in sales commissions attributable to the growth in
the number of clients and worksite employees.

     Other general and administrative expenses were $10.9 million for the six
months ended June 30, 1997, compared to $8.8 million for the six months ended
June 30, 1996, representing an increase of $2.1 million, or 23.9%. This
increase was primarily a result of expanded sales and marketing programs for
1997.  The balance of the increase was attributable to the growth in the
numbers of clients and worksite employees.

     Depreciation and amortization expenses increased by $0.4 million for the
six months ended June 30, 1997, compared to the six months ended June 30, 1996,
representing an increase of 23.2%. This increase was primarily the result of
the Company's investment in management information systems hardware.
Amortization of capitalized software costs associated with the Company's
development of new payroll processing and management information systems began
July 1997, when the systems became operational. These costs will be amortized
over a seven-year period.

     Interest expense was $1.3 million for the six months ended June 30, 1997,
compared to $1.9 million for the six months ended June 30, 1996, representing a
decrease of $0.6 million, or 31.6%. This decrease was primarily the result of 
the reduction in the Company's long-term borrowings.

     Net income was $7.7 million for the six months ended June 30, 1997,
compared to a loss of $2.2 million for the six months ended June 30, 1996,
representing an increase of $9.9 million, as a result of the factors discussed
above.

     The Company will adopt the Statement of Financial Accounting Standards No.
128, "Earnings Per Share" ("FAS 128") in the fourth quarter of 1997, as
required. The Company 

                                Page 14 of 18
<PAGE>   15
will continue to apply APB Opinion No. 15, "Earnings Per Share" until the 
adoption of FAS 128. The standard specifies the computation, presentation and 
disclosure requirements for earnings per share.

Liquidity and Capital Resources

     The Company periodically evaluates its liquidity requirements, capital
needs and availability of capital resources in view of its plans for expansion,
including potential acquisitions, anticipated levels of health benefit plan
subsidies and other operating cash needs. The Company has in the past sought,
and may in the future seek, to raise additional capital or take other measures
to increase its liquidity and capital resources. Historically, these funds have
been raised from the Company's partners, as well as from bank financing and
operations. The Company currently believes that the proceeds from the IPO, cash
flow from operations, and vendor financing arrangements will be sufficient to
meet its liquidity requirements through 1998. The Company may rely on these
same sources, as well as public or private debt and/or equity financing, to
meet its long-term liquidity needs.

     At June 30, 1997 and December 31, 1996, the Company had negative working
capital of $32.1 million, and $32.2 million, respectively, an improvement at
June 30, 1997 of $0.1 million. The improvement was primarily due to an increase
in current assets offset by a lesser increase in current liabilities. In
anticipation of the IPO, the Company prepaid certain capital lease obligations
in the amount of $2.7 million, of which $2.1 million was current.  The negative
working capital at each such balance sheet date was the result of the Company's
investment of $19.7 million in its facilities and technology infrastructure as
well as its subsidy of $31.7 million of costs related to the Company's health
benefit plans during the period January 1995 through June 1997. The Company's
primary short-term liquidity requirements relate to the payment of accrued
payroll and payroll taxes of its internal and worksite employees, accounts
payable for capital expenditures and the payment of accrued workers'
compensation expense and health benefit plan premiums. At June 30, 1997, the
Company had $10.0 million available under its vendor financing arrangements.

</TABLE>

     Net cash from operating activities increased by $20.0 million or 238.1%
for the six months ended June 30, 1997, as compared to the six months ended
1996.  The change was due primarily to a $9.8 million increase in net income
and a $8.6 million increase in accounts payable and other accrued liabilities.
The increase in accounts payable and other accrued liabilities is due primarily
to the timing of payments to vendors.

     Net cash used in investing activities during the six months ended June 30,
1997, and 1996, was not significantly different.  Capital expenditures,
primarily technology infrastructure, totaled $2.2 million for the six months
ended June 30, 1997.

     Net cash from financing activities decreased by $20.0 million or 185.2%
for the six months ended June 30, 1997, as compared to the six month period
ended 1996.  During the six month period ended June 30, 1996, the Company
received $17.8 million in preferred partner contributions.  During the six
month period ended June 30, 1997, $3.5 million of preferred partnership
interests were repurchased.

     On July 1, 1997, $15.2 million of the proceeds from the IPO were used to
repay in full amounts borrowed under the Company's existing credit agreement,
at which time the Company terminated the agreement.  The Company is currently
in discussions with several lenders concerning a new credit facility with rates
and terms more favorable than the 



                                Page 15 of 18

previous credit agreement. Of the proceeds from the IPO $13.6 million was used 
to repurchase the remaining preferred partnership interests that were not 
converted to common stock at the IPO.

Inflation

     The Company believes that inflation in salaries and wages of worksite
employees has a positive impact on its results of operations as its service fee
is proportional to such changes in salaries and wages.
