              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS




1.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     The accompanying unaudited condensed consolidated financial statements have
been prepared by the Company in accordance with generally accepted accounting
principles for interim financial information and substantially in the form
prescribed by the Securities and Exchange Commission (the "Commission") in
instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do
not include all of the information and footnotes required by generally accepted
accounting principles for complete financial statements. In the opinion of the
Company's management, the December 31, 1998 and 1997 unaudited interim financial
statements include all adjustments, consisting of normal recurring adjustments,
necessary for a fair presentation of results for this interim period. In the
opinion of the Company's management, the disclosures contained in this Form 10-Q
are adequate to make the information presented not misleading when read in
conjunction with the Notes to Consolidated Financial Statements included in the
Company's Form 10-K for the year ended March 31, 1998. The results of operations
for the three month and nine month periods ended December 31, 1998 are not
necessarily indicative of the results to be expected for the full year or for
any future period.


2.   NET INCOME PER SHARE

     Net income per share is computed using the weighted average number of
common and dilutive shares outstanding during the period. A reconciliation of
the numerators and denominators of the basic and diluted per share computations
are as follows:

THREE MONTHS ENDED DECEMBER 31, 1998 COMPARED TO THREE MONTHS ENDED 
DECEMBER 31, 1997

     REVENUES. Revenues for the three months ended December 31, 1998 increased
$72.1 million, or 56%, compared to revenues for the three months ended December
31, 1997. Approximately 67% of the increase in revenues was attributable to a
31% increase in the number of pharmacy claims processed during the period. The
increase in claims resulted from new contracts signed throughout the last twelve
months with new clients, as well as internal growth from existing clients.
Substantially all of the new clients utilize the Company's pharmacy network. In
cases in which the Company has an independent obligation to pay its network
pharmacy providers, the Company includes payments from its plan sponsors for
these benefits as revenues and payments to its pharmacy providers as cost of
revenues. Therefore, new clients that utilize the Company's network will
generate higher revenues than new business where the Company merely administers
the client's network. Approximately 18% of the increase in revenues was
attributable to additional sales of the Company's mail pharmacy services,
resulting from a 60% increase in the number of mail prescriptions dispensed. The
remaining 15% of the increase in revenues resulted from an increase in clinical
services revenues derived from formulary and disease management services as well
as clinical trials.

     COST OF REVENUES. Cost of revenues for the three months ended December 31,
1998 increased by $69.9 million, or 57%, compared to the same period in the
prior year. This increase was attributable primarily to the additional costs
associated with the Company's claims processing growth and the new clients that
are utilizing the Company's retail pharmacy network. As a percentage of
revenues, cost of revenues was approximately 96.0% in the three months ended
December 31, 1998 compared to 95.5% in the same period in the prior year.

     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and
administrative expense for the three months ended December 31, 1998 increased by
$772,000, or 28%, compared to the same period in the prior year. This increase
was the result of the Company's expansion of its sales and marketing activities,
as well as increases in administrative and support staff levels and salaries and
benefits in response to volume growth in all services. In spite of the increase,
selling, general and administrative expenses as a percentage of revenues
decreased from 2.1% for the three months ended December 31, 1997 to 1.7% in the
same period in 1998 as the result of greater economies of scale and due to the
increase in revenues associated with the Company's claims processing services.
Additional revenues generated by clients utilizing the Company's network
pharmacy providers typically do not result in an increase in selling, general
and administrative expenses.

     INTEREST INCOME AND INTEREST EXPENSE. Interest income, net of interest
expense, for the three months ended December 31, 1998 increased $45,000 compared
to the same period in the prior year. The Company incurred no interest expense
in the three months ended December 31, 1998 since the Company had no outstanding
indebtedness during the period.

     INCOME TAXES. For the three months ended December 31, 1998 and 1997, the
Company recorded income tax expense based upon an estimated, effective tax rate
of 38%.

     NET INCOME PER SHARE. The Company reported diluted net income per share of
$.28 per share for the three months ended December 31, 1998 compared to $.20 per
share for the same period in the prior year. The weighted average shares
outstanding were 11.5 million and 11.6 million for the three months ended
December 31, 1997 and 1998, respectively. The increase in the weighted average
shares resulted primarily from the increase in the Company's stock price which
has resulted in more options and warrants becoming dilutive securities. (See
Note 2 for calculation.)

NINE MONTHS ENDED DECEMBER 31, 1998 COMPARED TO NINE MONTHS ENDED 
DECEMBER 31, 1997

     REVENUES. Revenues for the nine months ended December 31, 1998 increased
$221.6 million, or 68%, compared to revenues for the nine months ended December
31, 1997. Approximately 70% of the increase in revenues was attributable to a
33% increase in the number of pharmacy claims processed during the period. The
increase in claims resulted from new contracts signed throughout the last twelve
months with new clients, as well as internal growth from existing clients.
Substantially all of the new clients utilize the Company's pharmacy network. In
cases in which the Company has an independent obligation to pay its network
pharmacy providers, the Company includes payments from its plan sponsors for
these benefits as revenues and payments to its pharmacy providers as cost of
revenues. Therefore, new clients that utilize the Company's network will
generate higher revenues than new business where the Company merely administers
the client's network. Approximately 16% of the increase in revenues was
attributable to additional sales of the Company's mail pharmacy services,
resulting from a 58% increase in the number of mail prescriptions dispensed. The
remaining 14% of the increase in revenues resulted from an increase in clinical
services revenues derived from formulary and disease management services as well
as clinical trials.

     COST OF REVENUES. Cost of revenues for the nine months ended December 31,
1998 increased by $213.4 million, or 69%, compared to the same period in the
prior year. This increase was attributable primarily to the additional costs
associated with the Company's claims processing growth and the new clients that
are utilizing the Company's retail pharmacy network. As a percentage of
revenues, cost of revenues was approximately 95.9% in the nine months ended
December 31, 1998 compared to 95.5% in the same period in the prior year.

     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and
administrative expense for the nine months ended December 31, 1998 increased by
$2.8 million, or 39%, compared to the same period in the prior year. This
increase was the result of the Company's expansion of its sales and marketing
activities, as well as increases in administrative and support staff levels and
salaries and benefits in response to volume growth in all services. In spite of
the increase, selling, general and administrative expenses as a percentage of
revenues decreased from 2.2% for the nine months ended December 31, 1997 to 1.8%
in the same period in 1998 as the result of greater economies of scale and due
to the increase in revenues associated with the Company's claims processing
services. Additional revenues generated by clients utilizing the Company's
network pharmacy providers typically do not result in an increase in selling,
general and administrative expenses.

     INTEREST INCOME AND INTEREST EXPENSE. Interest income, net of interest
expense, for the nine months ended December 31, 1998 increased $163,000 compared
to the same period in the prior year. The Company incurred no interest expense
in the nine months ended December 31, 1998 since the Company had no outstanding
indebtedness during the period. The increase also resulted from higher cash
balances invested in cash management programs which utilized the Company's
short-term excess cash to generate interest income through investment in money
market funds and high-grade commercial paper.

     INCOME TAXES. For the nine months ended December 31, 1998 and 1997, the
Company recorded income tax expense based upon an estimated, effective tax rate
of 38%.

     NET INCOME PER SHARE. The Company reported diluted net income per share of
$.79 per share for the nine months ended December 31, 1998 compared to $.51 per
share for the same period in the prior year. The weighted average shares
outstanding were 11.3 million and 11.6 million for the nine months ended
December 31, 1997 and 1998, respectively. The increase in the weighted average
shares resulted primarily from the increase in the Company's stock price which
has resulted in more options and warrants becoming dilutive securities. (See
Note 2 for calculation.)


LIQUIDITY AND CAPITAL RESOURCES

     As of December 31, 1998, the Company had working capital of $11.5 million.
During the quarter, working capital decreased by $25 million as the result of
the December 1998 acquisition of Baumel-Eisner. The Company's net cash provided
by operating activities was $33.8 million for the nine months ended December 31,
1998 due to the timing of the collection of certain receivables and the payment
of certain payables. During the nine months ended December 31, 1998 the Company
used cash of $5.2 million for purchases of property, plant and equipment
associated with the growth and expansion of the Company's systems and
facilities. In addition, the Company used cash of $25 million for the
acquisition of Baumel-Eisner. The Company anticipates that cash from operations,
combined with the proceeds remaining from its initial public offering will be
sufficient to meet the Company's internal operating requirements and expansion
programs, including capital expenditures, for at least the next 18 months.

YEAR 2000 READINESS DISCLOSURE

     The Company's operations are dependent upon its computer systems and
information technology. In fiscal year 1998 the Company began addressing the
Year 2000 issue by forming a Year 2000 project team. Year 2000 compliance
relates to: technology, including but not limited to, information technology,
embedded systems, or any other electro-mechanical or processor-based system.
Such technology, when used in accordance with its associated documentation, is
capable of accurately processing, providing and/or receiving date data from,
into and between the twentieth and twenty-first centuries, and the years 1999
and 2000, including leap year calculations. In the quarter ending June 30, 1998,
the Company completed the "inventory" portion of its Year 2000 project. The
Company documented all internal hardware, software or equipment that was date
sensitive.

     In the quarter ending September 30, 1998, the Company completed the second
stage of the Year 2000 project which involved assessing all of the items that
had been "inventoried" to determine whether they were Year 2000 compliant. This
assessment stage also included surveying all external vendors and customers that
transact business with the Company to determine whether their systems were Year
2000 compliant.

     In the quarter ending December 31, 1998, the Company completed the third
stage of the Year 2000 project which involved the development of code to convert
systems that are not compliant to Year 2000 compliant systems. The final stage
involves the testing of all technical systems to verify Year 2000 compliance.
All systems are expected to be tested and implemented by the end of March 1999.
While implementation is scheduled to be complete by March 31, 1999, further
maintenance testing and certifications will continue through 1999. Contingency
planning has also begun in order to ensure non-interruption of business
processes in the event of unexpected problems.

     The Company has and will incur internal and external personnel costs as
well as other expenses related to this project. Although the Company is still
evaluating the overall costs associated with the Year 2000 project, the Company
does not believe the associated costs are or will be material to the Company's
results of operations or financial condition. However, there can be no assurance
that the Company's efforts to address the Year 2000 issue will be entirely
successful. In addition, there can be no assurance that the software and systems
of other companies from which the Company transacts business will become Year
2000 compliant in a timely manner. Any such failures could have a material
adverse effect on the Company's systems and operations. The above information is
the Company's Year 2000 Readiness Disclosure. This disclosure is made pursuant
to and is intended to be covered by the provisions of the federal Year 2000
Information and Disclosure Act.
