                 MEDICAL MANAGER CORPORATION AND SUBSIDIARIES
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1)  Financial statement presentation:

     The accompanying unaudited consolidated financial statements of Medical
Manager Corporation and subsidiaries ("Medical Manager" or the "Company") have
been prepared in accordance with the rules and regulations of the Securities and
Exchange Commission and do not include all of the information and footnotes
required by generally accepted accounting principles for complete financial
statements. These consolidated financial statements should be read in
conjunction with the audited consolidated financial statements and notes thereto
included in the Company's Annual Report on Form 10-K for the year ended June 30,
1999. The results of the interim periods presented herein are not necessarily
indicative of the results to be expected for any other interim period or the
full year. In the opinion of management, the information furnished reflects all
the adjustments (consisting only of normal recurring accruals) considered
necessary for a fair presentation of the results for the reported interim
periods.

     Principles of Consolidation--

     The accompanying unaudited consolidated financial statements include the
accounts of the Company and its wholly-owned operating subsidiaries, Medical
Manager Health Systems, Inc. ("MMHS"), Porex Corporation (collectively with the
Company's other plastics and filtration technology subsidiaries referred to
herein as "Porex"), and its majority owned operating subsidiary, CareInsite,
Inc. ("CareInsite"), after elimination of all material intercompany accounts and
transactions.

     Certain reclassifications have been made to prior year amounts to conform
to the current year presentation.

(2)  Business combinations:

     The Merger--

     On July 23, 1999 the Company (formerly known as Synetic, Inc.) acquired all
of the outstanding stock of MMHS (formerly known as Medical Manager Corporation)
in exchange for 14,109,455 newly issued shares of the Company's common stock. In
connection with this acquisition, the Company changed its name to Medical
Manager Corporation. The merger has been accounted for as a tax-free pooling-of-
interests. The financial statements reflect the historical operations of the
Company for all periods prior to the business combination, and have been
retroactively restated to include the financial position, results of operations
and cash flows of MMHS.

     Pooling-of-Interest Transactions--

     During the three months ended September 30, 1999, the Company acquired the
following resellers of the Medical Manager Software: Computer Business
Solutions, Inc. based in Indianapolis, Indiana and Modern Business Machines,
Inc. based in Chadron, Nebraska. The Company also acquired LaPook Lear Systems,
Inc. located in New York, New York (the "Acquired Companies"). The aggregate
consideration paid for the Acquired Companies was 98,390 shares of the Company's
common stock.

     The acquisitions of the Acquired Companies were accounted for using the
pooling of interests method of accounting. The Company's results of operations
and cash flows for the three months ended September 30, 1999 reflect the results
of operations and cash flows of the Acquired Companies as if they were acquired
as of July 1, 1999. Prior periods have not been restated as the combined results
would not be materially different from the results as previously presented.

     Purchase Business Combinations--

     During the quarter ended September 30, 1999, the Company executed and
closed definitive agreements to acquire substantially all of the assets or all
of the outstanding equity securities of the following companies (the "Purchased

Abacus Data Systems, Inc.                    September 27, 1999       Elkhart, Indiana
</TABLE>

     The Purchased Companies were accounted for using the purchase method of
accounting. The aggregate consideration paid for the Purchased Companies was
$13,125,000 in cash and 91,436 shares of the Company's common stock. The results
of the Purchased Companies are reflected from their respective acquisition
dates. The impact of the Purchased Companies on revenue, net income and earnings
per share is not significant. Pro forma information has not been presented as
the pro forma results would not be materially different from the results as
presented.

     For the three months ended September 30, 1999, the Company recorded
$17,991,000 of acquisition and related expenses primarily related to the
acquisition of MMHS. The major components of this charge are as follows:
$10,567,000 of transaction costs such as financial advisory fees, professional
fees and printing fees; $5,718,000 of amounts vested, as a result of the
acquisition, under certain MMHS employment agreements; $1,259,000 of acquisition
related severance costs attributable to employees terminated or notified of
termination as of September 30, 1999 and; $447,000 of other related expenses.

(3)  Inventories:

     Inventories consisted of the following (in thousands):

(4)  Marketable securities:

     Management determines the appropriate classification of its investments in
debt securities at the time of purchase and re-evaluates such determinations at
each balance sheet date. Debt securities are classified as held-to-maturity when
the Company has the positive intent and ability to hold the securities to
maturity. Held-to-maturity securities are carried at cost, net of unamortized
premium or discount. Debt securities for

                                      -8-
<PAGE>

which the Company does not have the intent or ability to hold to maturity are
classified as available-for-sale. Available-for-sale securities are carried at
fair value as of the balance sheet date. At September 30, 1999, the Company's
investments consisted principally of U.S. Treasury Notes and Federal Agency
Notes. Of the investments at September 30, 1999, $50,000,000 were debt
securities classified as available-for-sale maturing in June 2001. Unrealized
losses on these securities were $15,000 at September 30, 1999 and gross
unrealized gains on marketable debt securities classified as available-for-sale
were $278,000 at June 30, 1999.

(5)  Computation of net income per share:

     Basic net income per share is computed by dividing net income by the
weighted average number of common shares outstanding for the period. Diluted net
income per share reflects the potential dilution that could occur if securities
or other contracts to issue common stock were exercised or converted into common
stock. The Company's 5% Convertible Subordinated Debentures due 2007 (the
"Convertible Debentures"), if converted, would not have had a dilutive effect on
net income per share for the periods presented.

     A reconciliation of weighted average shares outstanding (basic) to weighted
average shares outstanding assuming dilution (diluted) follows (in thousands):

(7)  Accumulated other comprehensive  loss:

     Effective July 1, 1998, the Company adopted Statement of Financial
Accounting Standards No. 130-"Reporting Comprehensive Income" (SFAS No. 130").
SFAS No. 130 increases financial reporting disclosures and has no impact on the
Company's financial position or results of operations.

     Comprehensive (loss) income amounted to $(10,299,000) and $6,408,000 for
the three months ended September 30, 1999 and 1998, respectively. The elements
of accumulated other comprehensive loss for the Company arise as a result of the
change in foreign currency translation adjustments and the change in

                                      -9-
<PAGE>

unrealized gains and losses on marketable securities.

(8)  America Online agreement:

     In September 1999, CareInsite entered into a strategic alliance with
America Online, Inc. ("AOL") for CareInsite to be AOL's exclusive provider of a
comprehensive suite of services that connect AOL's 18 million members, as well
as CompuServe members and visitors to AOL's Web-based services, Netscape,
AOL.COM and Digital City (collectively, "AOL Members"), to physicians, health
plans, pharmacy benefit managers, covered pharmacies and labs. Under the
agreement, CareInsite and AOL have agreed to create co-branded sites which will
enable AOL Members to manage their healthcare through online communication with
their physicians, health plans, pharmacy benefit managers, covered pharmacies
and labs. The agreement has an initial term of four years. Through this
arrangement, AOL Members will have access to CareInsite's secure, real-time
services being developed that allow them, among other things, to select and
enroll in health plans, choose their providers, schedule appointments, renew and
refill plan-approved prescriptions, view lab results, review claims status,
receive explanations of benefits, review patient education material provided by
their health plans, understand plan polices and procedures and receive plan
treatment authorizations. CareInsite and AOL have also agreed to collaborate in
sales and marketing to the healthcare industry, and they intend to leverage
their alliance into cross-promotional and shared advertising revenue
initiatives. Under the financial terms of the arrangement, CareInsite has agreed
to make $30,000,000 of guaranteed payments to AOL over three years. CareInsite
has made the first payment of $10,000,000 in September 1999.

     CareInsite also entered into a four year agreement with Netscape
Communications Corporation ("Netscape") under which CareInsite acquired a
nonexclusive and nontransferable right and license for the use of an unlimited
quantity of the Netscape and Sun Microsystems software offered via the Sun
Microsystems-Netscape Alliance. The cost of the products was $3,750,000, with a
maintenance fee of $750,000 in the initial year, and an option to purchase
maintenance at $1,000,000 per year in the second, third and fourth year of the
agreement.

     Under a separate agreement entered into in September 1999, AOL purchased
100 shares of newly issued CareInsite Series A Convertible Redeemable Preferred
Stock ("CareInsite Preferred Stock") at a price of $100,000 per share, or $10
million of CareInsite Preferred Stock in the aggregate, with an option to
purchase up to an additional 100 shares of CareInsite Preferred Stock in
September 2000 at the same price ("CareInsite Preferred Option"). At the option
of AOL, in March 2002, the CareInsite Preferred Stock is either redeemable in
whole for $100,000 per share in cash or convertible in whole, on a per share
basis, into (i) the number of shares of CareInsite's common stock equal to
$100,000 divided by $49.25 (or 2,030.5 shares) and (ii) a warrant exercisable
for the same number or shares of CareInsite's common stock, or 2,030.5 shares,
at a price of $49.25 per share. In the event that AOL elects to convert the 100
shares of CareInsite Preferred Stock it purchased in September 1999, it would
receive 203,046 shares of CareInsite's common stock and a warrant exercisable
into an additional 203,046 shares at a price of $49.25 per share. Prior to
March 2002, AOL has the right to require CareInsite to redeem the CareInsite
Preferred Stock in whole at $100,000 per share in the event of a change in
control of CareInsite. The CareInsite Preferred Stock is non-voting except under
certain extraordinary circumstances and no dividend is payable on the CareInsite
Preferred Stock unless CareInsite declares a dividend on its common stock.

     The proceeds received of $10,000,000 were allocated based on the relative
fair values of the CareInsite Preferred Stock and the CareInsite Preferred
Option, as determined by management. Accordingly, $7,608,000 was allocated to
the CareInsite Preferred Stock and $2,392,000 was allocated to the CareInsite
Preferred Option. Additionally, as the CareInsite Preferred Stock is convertible
into equity securities with a value in excess of $10,000,000 (the "beneficial
conversion feature"), a portion of the proceeds has been allocated to the
beneficial conversion feature and is reflected as a discount to the CareInsite
Preferred Stock. The value of the beneficial conversion feature, as determined
by management, was $5,268,000. The discount is being amortized through March
2002 using the effective interest method and is reflected in minority interest
in net loss of consolidated subsidiary in the accompanying statement of
operations. The CareInsite Preferred

                                      -10-
<PAGE>

Stock and CareInsite Preferred Option are classified as a component of minority
interest in the accompanying balance sheet.

(9)  Commitments and contingencies:

     Legal proceedings--

     In the normal course of business, the Company is involved in various claims
and legal proceedings. While the ultimate resolution of these matters has yet to
be determined, the Company does not believe that their outcome will have a
material adverse effect on its financial position.

     On February 18, 1999, Merck & Co., Inc. ("Merck") and Merck-Medco Managed
Care, L.L.C. ("Merck-Medco") filed a complaint in the Superior Court of New
Jersey against the Company, CareInsite, Martin J. Wygod, Chairman of the Company
and CareInsite, and three officers and/or directors of the Company and
CareInsite, Paul C. Suthern, Roger C. Holstein and Charles A. Mele. The
plaintiffs assert that the Company, CareInsite and the individual defendants are
in violation of certain non-competition, non-solicitation and other agreements
with Merck and Merck-Medco, and seek to enjoin the Company and them from
conducting the Company's healthcare e-commerce business and from soliciting
Merck-Medco's customers. The Medical Manager and Mr. Wygod's agreements expired
May 24, 1999. Mr. Suthern's, Mr. Mele's and Mr. Holstein's agreements expire in
December 1999, March 2000 and September 2002, respectively.

     A hearing was held on March 22, 1999 on an application for a preliminary
injunction filed by Merck and Merck-Medco. On April 15, 1999, the Superior Court
denied this application. The Company believes that Merck's and Merck- Medco's
positions in relation to it and the individual defendants are without merit and
the Company intends to vigorously defend the litigation. However, the outcome of
complex litigation is uncertain and cannot be predicted at this time. Any
unanticipated adverse result could have a material adverse effect on the
Company's financial condition and results of operations.

     The Company has recorded $650,000 in litigation costs associated with the
Merck and Merck-Medco litigation in the three months ended September 30, 1999.

     Porex Technologies Corp. has been named as one of many co-defendants in a
number of actions brought by recipients of silicone mammary implants. Certain of
the actions against Porex have been dismissed or settled by the manufacturer of
the implants or insurance carriers of Porex without material cost to Porex. The
Company believes its insurance coverage provides adequate coverage against
liabilities that could arise from actions or claims arising out of Porex's
distribution of implants.

     A class action lawsuit was brought against the Company alleging Year 2000
issues regarding the Medical Manager software in versions prior to Version 9.0.
Seven additional lawsuits were also brought against the Company, each purporting
to sue on behalf of those similarly situated and raising essentially the same
issues. In March 1999, the Company entered into an agreement to settle the class
action lawsuit, as well as five of the seven other similar cases. The settlement
created a settlement class of all purchasers of Version 7 and 8 and upgrades to
Version 9 of the Medical Manager software, and released the Company from Year
2000 claims arising out of the sales of these versions of the Company's product.
Under the terms of the settlement, Version 8.12, containing the Company's
upgraded Version of 8.11 software in addition to the Year 2000 patch, will be
licensed without a license fee to Version 7 and 8 users who participate in the
settlement. In addition, the settlement also provided that participating users
who purchased a Version 9 upgrade will have the option to obtain one of four
optional modules from the Company without a license fee, or to elect to take a
share of a settlement cash fund. The settlement required the Company to make a
cash payment of $1,455,000. Pursuant to the settlement, the Company was released
from liability due to the Year 2000 non-

                                      -11-
<PAGE>

compliance of Versions 7 and 8 by all users of Version 7 and 8 except 29 users
who opted-out of the class settlement.

     A lawsuit was filed against the Company and certain of its officers and
directors, among other parties, on October 23, 1998 in the United States
District Court for the Middle District of Florida. The lawsuit, styled George
Ehlert, et al. vs. Michael A. Singer, et al., purports to bring an action on
behalf of the plaintiffs and others similarly situated to recover damages for
alleged violations of the federal securities laws and Florida laws arising out
of the Company's issuance of allegedly materially false and misleading
statements covering its business operations, including the development and sale
of its principal product, during the class period. An amended complaint was
served on March 2, 1999. The class period is alleged to be between April 23,
1998 and August 5, 1998. The lawsuit seeks, among other things, compensatory
damages in favor of the plaintiffs and the other purported class members and
reasonable costs and expenses. The Company believes that this lawsuit is without
merit and intends to vigorously defend against it.

ITEM 2.   Management Discussion and Analysis of Financial Condition and Results
          of Operations

Overview

     On July 23, 1999 Medical Manager Corporation (the "Company") (formerly
known as Synetic, Inc.) acquired all of the outstanding stock of Medical Manager
Health Systems, Inc. (formerly known as Medical Manager Corporation) ("MMHS") in
exchange for 14,109,455 newly issued shares of Medical Manager Corporation
common stock. In connection with the acquisition, Synetic, Inc. changed its name
to Medical Manager Corporation. The acquisition has been accounted for as a tax-
free pooling-of-interests. The Company's consolidated financial statements have
been restated to reflect the merger with MMHS. Accordingly, management's
discussion and analysis of financial condition and results of operations reflect
the historical operation of Medical Manager Corporation, restated to reflect the
acquisition of MMHS for all periods presented. As discussed below, the Company
has recorded a charge in the three months ending September 30, 1999 for the
merger and other related costs.

     The historical operations of the Company are primarily related to its
physician practice management information systems business through its wholly
owned subsidiary, MMHS and its plastics and filtration technologies business
through Porex Corporation and its affiliated companies ("Porex"). For the three
months ended September 30, 1999, the majority of the Company's consolidated
revenues and operating expenses were derived from MMHS and Porex. For the three
months ended September 30, 1998, all of the Company's consolidated revenues and
a majority of its operating expenses were derived from MMHS and Porex. As
discussed below, the consolidated financial statements for the three months
ended September 30, 1999 and 1998 also include costs associated with the
Company's activities in developing its health care electronic commerce business
through the Company's majority owned subsidiary, CareInsite, Inc. and its
affiliated companies ("CareInsite").

Consolidated Results of Operations

     The Company's consolidated net revenues for the three months ended
September 30, 1999 increased $18,093,000 or 30.9% over the comparable prior year
period. Net revenues for the three months ended September 30, 1999 at MMHS
increased $7,333,000 or 19.3% over the prior year period. Of this increase
$3,159,000 was due to sales from purchased companies acquired from November 30,
1998 through September 27, 1999, for which there were no sales in the prior
period. Excluding these acquisitions, the increase in sales of $4,174,000 was
due primarily to increases in MMHS's network service revenues, new system sales
and upgrades to version 9.0 of the Medical Manager Software. Net revenues for
the three months ended September 30, 1999 at Porex increased $9,103,000 or 44.3%
over the prior year period. Included in this increase are revenues from Porex
Bio Products, Inc. (formerly known as Point Plastics, Inc.) and Porex Medical
Products, Inc. (formerly known as The KippGroup), which were acquired on July
21, 1998 and January 22, 1999, repectively. Excluding the impact of these
acquisitions, sales on a comparable basis over the prior year increased 2.4% due
primarily to increased sales in Porex's Bio Products group, primarily consisting
of laboratory products, partially offset by decreased sales by Porex's Porous
Products Group of components for consumer products, primarily writing instrument
components. Revenues at CareInsite for the three months ended September 30, 1999
were $1,657,000. Of these revenues, $877,000 were service revenues from the
management services provided to THINC. There were no revenues at CareInsite in
the comparable prior year period.

     The Company's consolidated cost of revenues as a percentage of revenues
increased to 50.4% from 48.8% in the prior year. Cost of revenues as a
percentage of revenues at MMHS increased to 53.0% from 49.8% in the prior year.
The increase relates to fewer lower margin sales by MMHS' enterprise business
group, which are typically large high margin sales made to larger national and
regional clients and to a lesser extent, certain purchased companies which
experienced lower margins than historically reflected by MMHS. Cost of revenues
as a percentage of revenues at Porex decreased to 45.4% from 47.0% in the prior
year. The decrease relates

                                      -14-
<PAGE>

to continued improvements in manufacturing efficiencies throughout Porex. Cost
of revenues at CareInsite was $1,131,000 for the three months ended September
30, 1999, of which $877,000 was cost of services to affiliates, consisting
primarily of employee and related expenses for those employees supporting the
THINC business.

     The Company's consolidated selling general and administrative expenses for
the three months ended September 30, 1999, decreased to 26.9% of net revenues
from 28.3% in the comparable prior year period. Selling general and
administrative expenses at MMHS decreased to 23.0% of net revenues, from 27.2%
in the comparable prior year period. This decrease is principally due to
increased sales which were not proportionately offset by expenses, since these
expenses do not vary directly with sales. Selling general and administrative
expenses at Porex increased to 20.4% of net revenues from 18.4% in the
comparable prior year period. The increase over the prior year is a result of an
overall increase in marketing efforts at Porex, including additional marketing
personnel and increased advertising and trade show activities. Selling general
and administrative expenses at CareInsite increased $1,299,000 over the
comparable prior year period. The increase is primarily due to additional
salaries and benefits, promotional expenses and continued business development
efforts to develop the CareInsite business.

     The Company's consolidated research and development expenses increased
$3,096,000 over the comparable prior year period due primarily to $2,366,000 of
research and development expenses capitalized in the prior year period at
CareInsite, for which there was no comparable amount in the current year and the
continued development of CareInsite's product. The increase is also related to
MMHS' development projects regarding future versions of the Medical Manager
software with graphical user interfaces and relational database technologies,
along with web-based access and services. In addition, the increase is due to
Porex continuing to develop new products, product applications and the continued
enhancement of its manufacturing processes.

     The Company's consolidated depreciation and amortization increased
$2,234,000 over the prior year, primarily related to the acquisitions of
Porex Medical Products, Inc. and resellers acquired at MMHS through purchase
business combinations, for which there were no amounts in the comparable prior
year period.

     The Company recorded $650,000 in litigation charges for the three months
ended September 30, 1999, related to its ongoing defense against assertions that
it violated certain agreements with Merck and Co., Inc. and Merck-Medco Managed
Care, L.L.C.

     For the three months ended September 30, 1999, the Company recorded
$17,991,000 of merger and related expenses primarily related to the merger with
MMHS. The major components of this charge are as follows: $10,567,000 of
transaction costs such as financial advisory fees, professional fees and
printing fees; $5,718,000 of amounts vested, as a result of the merger, under
certain MMHS employment agreements; $1,259,000 of merger related severance costs
attributable to employees terminated or notified of termination as of September
30, 1999 and; $447,000 of other related expenses.

     The Company's consolidated interest and other income, net of interest
expense, increased by $1,715,000 for the three months ended September 30, 1999,
over the comparable prior year period. This increase was primarily due to
increased investments from funds raised as a result of CareInsite's initial
public offering.

     The increase in the effective tax rate is a result of CareInsite's losses
which are no longer included in the Company's consolidated federal income tax
return as well as a significant portion of the merger expenses which are not
currently deductible for federal or state income tax purposes.

                                      -15-

Capital Resources and Liquidity

     As of September 30, 1999, the Company had $73,661,000 of cash and cash
equivalents and $362,381,000 of marketable securities. At September 30, 1999,
the Company's marketable securities consisted primarily of U.S. Treasury Notes
and Federal Agency Notes.

     Net cash used in operating activities for the three months ended September
30, 1999 was $2,544,000, an increase of $11,643,000 from the comparable prior
year period. This increase was primarily related to the merger expenses for the
merger with MMHS, as well as higher expenditures related to the development of
CareInsite.

     Net cash used in investing activities was $86,704,000 for the three months
ended September 30, 1999, reflecting purchases of marketable securities, net of
maturities and redemptions as well as the net cash paid for the businesses
acquired and capital expenditures during the past fiscal quarter.

     Net cash provided by financing activities was $10,379,000 for the three
months ended September 30, 1999, primarily a result of the issuance of
convertible redeemable preferred stock ("Preferred Stock") by CareInsite. The
funds generated from financing activities are reinvested in existing businesses
and are used to fund capital expenditures.

     As a result of the continuing efforts in developing CareInsite, CareInsite
has incurred substantial operating losses since its inception and there can be
no assurance that CareInsite will generate significant revenues or profitability
in the future. CareInsite intends to significantly increase its expenditures
primarily in the areas of development, sales and marketing, data center
operations and customer support. CareInsite expects to incur substantial
operating losses for at least the next two fiscal years.

     The Company believes that its cash flow from operations, the income earned
on its investments, and the funds generated by CareInsite from the issuance of
its common stock and Preferred Stock are sufficient to meet the anticipated
working capital requirements of both the Company's and CareInsite's business,
including the anticipated increased expenditures related to CareInsite noted
above.

     The Company continues to pursue an acquisition program pursuant to which it
seeks to affect one or more acquisitions or other similar business combinations
with businesses it believes have significant growth potential. Financing for
such acquisitions may come from several sources, including, without limitation,
(i) the Company's cash, cash equivalents and marketable securities and (ii)
proceeds from the incurrence of additional indebtedness or the issuance of
common stock, preferred stock, convertible debt or other securities. There can
be no assurance that the Company's acquisition program will be successful.

Year 2000 Compliance

     Many currently installed computer systems and software products are coded
to accept or recognize only two digit entries for the year in the date code
field. These systems and software products will need to accept four digit year
entries to distinguish 21st century dates from 20th century dates. As a result,
computer systems and/or software used by many companies and governmental
agencies may need to be upgraded to comply with such Year 2000 requirements or
risk system failure or miscalculations causing disruptions of normal business
activities.

     Each of the Company's three businesses have made an assessment of its Year
2000 readiness and of the risks related to the year change.

     Medical Manager Health Systems.  Medical Manager Health Systems has
     -------------------------------
completed the upgrade and review of the following internal systems which are
currently Year 2000 compliant: (i) financial and accounting software; (ii)
software package to assist in recording, assigning, and clearing customer
hardware and support calls; (iii) telecommunication systems which include not
only voice communications, but significant data communications such as e-mail
and an internal network providing each subsidiary access to servers located at
the corporate offices.

     As a result of its Year 2000 Compliance Team's efforts, Medical Manager
Health Systems has noted that a portion of the current in-house personal
computers are known to be non-Year 2000 compliant. Some workstations also have
software programs installed which are not Year 2000 compliant. Medical Manager
Health Systems has defined a minimum standard Year 2000 compliant workstation
with standardized software. To date, all mission critical workstations have been
made Year 2000 compliant with the industry standard hardware and software.
Medical Manager Health Systems maintains various non-mission critical
workstations which may not be Year 2000 compliant. Medical Manager Health
Systems does not intend to take a pro-active approach to replacing or upgrading
these computers until it is necessary. The cost of Medical Manager Health
System's Year 2000 compliance program was not material.

     The Y2K Compliance Team has recognized two critical data bases used
internally by Medical Manager Health Systems. Both of these data bases, the
Network Services Client Enrollment and the MM software serialization data base,
are currently Y2K compliant.

     The third party relationships identified as critical to Medical Manager
Health Systems' operations are computer hardware distributors and shipping
companies. As part of a standardization initiative which began in late 1997,
Medical Manager Health Systems works with three national distributors to
supply all hardware and third party software products sold to clients. All three
companies have provided documents stating that they are Year 2000 ready. In
addition, all shipping companies used by Medical Manager Health Systems and its
vendors have confirmed their Year 2000 readiness.

     Medical Manager Health Systems intends to continue to monitor the Year 2000
compliance of its internal software and hardware packages, telecommunications
systems, and vendors. In the event that any of Medical Manager Health Systems'
systems, or any of Medical Manager Health Systems' vendors' systems, do not meet
the Year 2000 requirement by December 31, 1999, Medical Manager Health Systems
could experience difficulties in, including but not limited to, processing sales
and other financial information, customer support calls, serializations of
Medical Manager Health Systems' product, and orders of supplies from vendors.
This could have a material adverse effect on the Company's financial position,
results of operations, or business. Although Medical Manager Health Systems
expects its systems, and its vendors' systems, to be Year 2000 compliant on or
before December 31, 1999, it cannot predict the success of Medical Manager
Health Systems' Year 2000 compliance program. Medical Manager Health Systems has
not adopted a contingency plan to address possible

                                      -17-
<PAGE>

risks to its systems. If Medical Manager Health Systems experiences a failure in
its Year 2000 preparedness, experienced staff will be redeployed to address any
potential Year 2000 compliance issues.

     The Year 2000 issue also creates risk for Medical Manager Health Systems
from problems that may be experienced by customers of its software. While
Version 9 of The Medical Manager practice management system, which was
commercially released in November 1997, is Year 2000 compliant, prior versions
of the system are not. Medical Manager Health Systems has encouraged users of
pre-Version 9 versions of The Medical Manager software to upgrade to Version 9
in order to become Year 2000 compliant. Medical Manager Health Systems has
developed a patch that would allow prior Versions 7 and 8 to handle the date
change to the new century. However, there is no assurance that Versions 7 and 8,
with or without the Year 2000 patch will not create additional issues for users
of the software including, but not limited to, additional costs for upgraded
hardware, additional costs for new operating systems and personnel training,
additional costs for conversion of Version 7 data, and the fact that Versions 7
and 8 do not take into account current industry and regulatory requirements.
Version 9 will remain the only enhanced and maintained version of the software.

     Additionally, there can be no assurance that the existence of the Year 2000
patch will not delay or reduce the migration of users to Version 9 from earlier
versions. Further, if Version 9 or other customers experience significant
difficulties as a result of the Year 2000 issue, or if Medical Manager Health
Systems encounters difficulties in responding in a timely manner to customer
requests to upgrade to Version 9, there could be a material adverse impact on
the Company's results of operations, financial condition or business.

     Porex. Porex has completed an assessment of its Year 2000 readiness.

Porex has completed the conversion of all significant non-manufacturing related
systems. As of June 30, 1999, Porex had completed and fully tested the
conversion of its manufacturing related information technology ("IT") systems.
For manufacturing related, non-IT systems, all significant microprocessor-
embedded production equipment has been upgraded and Porex believes it is Year
2000 compliant.

     Porex has communicated with its key suppliers and customers concerning the
state of their readiness for the Year 2000. All of such suppliers and customers
have confirmed that their systems are ready for the year change. If third
parties upon which Porex relies are ultimately unable to address this issue in a
timely manner, such occurrence could result in a material risk to the Company.

     The cost of Year 2000 compliance for Porex was not material.

     Porex has in inventory a reserve of raw materials, which it believes will
be sufficient to avoid a disruption in its manufacturing process in order to
minimize the risk associated with third-party suppliers experiencing Year 2000
problems.

     As the Year 2000 issue has many elements and potential consequences, some
of which are not reasonably foreseeable, the ultimate impact of the Year 2000 on
Porex's, and thus the Company's operations could differ materially from its
expectations.

     CareInsite. CareInsite has made an assessment of the Year 2000 readiness of
     ----------
its information technology systems, including the hardware and software that
enable CareInsite to develop and deliver its healthcare e-commerce services as
well as its non-information technology systems. CareInsite's assessment
consisted of:

     .    quality assurance testing of CareInsite's internally developed
          proprietary software;

     .    contacting third-party vendors and licensors of material hardware,
          software and services that are both directly and indirectly related to
          developing CareInsite's healthcare e-commerce network;

     .    contacting vendors of material non-IT systems;

                                      -18-
<PAGE>

     .    assessment of repair or replacement requirements;

     .    repair or replacement; and

     .    implementation.

     CareInsite has been informed by its vendors of material hardware and
software components of its IT systems that the products used by CareInsite are
currently Year 2000 compliant. CareInsite has also been informed by its non-IT
system vendors that the products used by CareInsite are currently Year 2000
compliant.

     To date, CareInsite has not incurred any material expenditures in
connection with identifying or evaluating Year 2000 compliance issues. Most of
CareInsite's expenses have related to, and are expected to continue to relate
to, the operating costs associated with time spent developing a Year 2000
compliant healthcare e-commerce channel.

     CareInsite is not currently aware of any Year 2000 compliance problems
relating to its information technology or non-information technology systems
that CareInsite believes would have a material adverse effect on its business,
financial condition and results of operations. There can be no assurance that
CareInsite will not discover Year 2000 compliance problems that will require
substantial revisions to CareInsite systems or services. In addition, there can
be no assurance that third-party software, hardware or services incorporated
into CareInsite's material information technology and non-information technology
systems will not need to be revised or replaced, all of which could be time
consuming and expensive. Any failure to fix CareInsite's information technology
systems or to replace third-party software, hardware or services on a timely
basis could result in lost revenues, increased operating costs, the loss of
customers and other business interruptions, any of which could have a material
adverse effect on CareInsite's business, results of operations and financial
condition.

     In addition, there can be no assurance that physicians, payers, suppliers,
Internet access companies, third-party service providers, vendors, business
partners and others outside CareInsite's control will be Year 2000 compliant.
The failure by such entities to be Year 2000 compliant could result in a
systemic failure beyond CareInsite's control, such as a prolonged Internet or
communications failure, which could also prevent CareInsite from delivering its
services to its customers, decrease the use of the Internet or prevent users
from accessing CareInsite's service. Such a failure could have a material
adverse effect on CareInsite's business, results of operations and financial
condition. Also, a general Year 2000 systemic failure could require healthcare
companies to spend large amounts of money to correct any such failures, reducing
the amount of money that might otherwise be available to be spent on the
CareInsite's services.

     CareInsite is continuing to assess and test its systems for Year 2000
compliance. CareInsite has also developed contingency plans for system failure,
service disruption and data corruption issues due to Year 2000 problems. In the
event that there is a system problem due to a Year 2000 date, CareInsite will
immediately attempt to diagnose and fix the problem. At the same time,
CareInsite will change (a) the system clock back to 1999 while separately
logging all transactions so affected and/or (b) the dates within transactions to
1999 while separately logging all transactions so affected. In the event that a
Year 2000 problem occurs at an external entity, that entity will be informed of
the problem and CareInsite will continue to review and repair the dates until
the problem is fixed. CareInsite makes no assurance that it will be able to
successfully diagnose and/or fix any Year 2000 problems that occur or that the
cost of doing so will not be material.

     As the Year 2000 issue has many elements and potential consequences, some
of which are not reasonably foreseeable, the ultimate impact of the Year 2000 on
CareInsite's operations could differ materially from CareInsite's expectations.
