                               PROSPECTUS SUMMARY
 
     The following summary is qualified in its entirety by, and should be read
in conjunction with, the more detailed information and the historical and pro
forma financial statements, including the notes thereto, appearing elsewhere in
this Prospectus or incorporated herein by reference. Unless otherwise indicated,
all share, per share and financial data set forth herein assume no exercise of
the Underwriters' over-allotment option. This Prospectus contains certain
forward-looking statements which may involve certain risks and uncertainties.
Actual results may differ materially from the results anticipated in these
forward-looking statements as a result of certain factors set forth under "Risk
Factors" and elsewhere in this Prospectus.
 
                                  THE COMPANY
 
     Medical Manager Corporation (the "Company") is a leading provider of
comprehensive physician practice management information systems to independent
physicians, independent practice associations ("IPAs"), management service
organizations ("MSOs"), physician practice management organizations ("PPMs"),
managed care organizations and other providers of health care services in the
United States. The Company develops, markets and supports The Medical Manager(R)
practice management system, which addresses the financial, administrative,
clinical and practice management needs of physician practices. The Company's
system has been implemented in a wide variety of practice settings from small
physician groups to multi-provider IPAs and MSOs. The Company's proprietary
systems enable physicians and their administrative staffs to efficiently manage
their practices while delivering quality patient care in a constantly changing
health care environment. Since the development of The Medical Manager in 1982,
the Company's installed base has grown to over 24,000 client sites, representing
more than 80 practice specialities, making it the most widely installed
physician practice management system in the United States.
 
     Based on industry sources, there are over 650,000 physicians in more than
140,000 medical practices in the United States. Increasing economic and
regulatory pressures and the growth of managed care organizations have
significantly expanded the demand for all physicians to produce, maintain and
better utilize practice information while controlling costs. As a result, the
Company believes approximately 90% of physician practices now use some type of
computer system for all or a portion of their information processing
requirements.
 
     The Company's business strategy is to build upon its leadership position as
the most widely utilized physician practice management system in the United
States. Key elements of this business strategy include: (i) capitalizing on the
Company's national market presence; (ii) continuing the consolidation and
rationalization of the existing national network of independent dealers for The
Medical Manager system; (iii) increasing penetration of MSOs and other large
physician groups; (iv) cross-selling existing and new products and services to
the Company's installed client base; and (v) continuing the Company's
development of new products, product enhancements and services.
 
     As part of the Company's initial public offering in February 1997 (the
"IPO"), the Company acquired in separate transactions (the "Mergers") five
businesses (each a "Founding Company" and collectively the "Founding Companies")
which were involved in one or more aspects of the development, sale and support
of The Medical Manager practice management system. Since the IPO, the Company
has implemented its strategy of acquiring selected independent dealers. As part
of this acquisition program, the Company has acquired an additional 26
independent dealers throughout the United States, each of which was involved in
the development, sale and support of The Medical Manager practice management
system.
 
     The Company conducts its operations through eight wholly-owned
subsidiaries. One of the subsidiaries engages in research and development
activities and another coordinates national sales and marketing activities. The
remaining six subsidiaries provide direct sales, marketing and support of The
Medical Manager to customers in the Company's six geographic regions, which
consist of the Northeast, Southeast, Midwest, Southwest, West and Northwest
regions.
 
     The Company's principal executive offices are located at 3001 North Rocky
Point Drive East, Suite 100, Tampa, Florida 33607 and its telephone number is
(813) 287-2990.

                                  RISK FACTORS
 
     Prospective investors should consider carefully the following risk factors,
together with the information contained in this Prospectus, in evaluating an
investment in the Common Stock offered hereby. The following factors and other
information set forth in this Prospectus contain certain forward-looking
statements involving risks and uncertainties. Actual results may differ
materially from the results anticipated in these forward-looking statements as a
result of certain factors set forth in this section and elsewhere in this
Prospectus.
 
RISKS ASSOCIATED WITH ACQUISITIONS
 
     As part of its growth strategy, the Company intends to acquire additional
independent dealers of The Medical Manager physician practice management system
and complementary technologies. There can be no assurance that the Company will
be able to identify, acquire or profitably integrate and manage additional
dealers or complementary technologies, if any, into the Company without
substantial costs, delays or other operational or financial problems. Further,
acquisitions involve a number of special risks, including possible adverse
effects on the Company's operating results, diversion of management's attention,
failure to retain key personnel of acquired entities, amortization of acquired
intangible assets and risks associated with unanticipated events or liabilities,
some or all of which could have a material adverse effect on the Company's
results of operations, financial condition or business. Customer dissatisfaction
or performance problems at a single acquired company could have an adverse
effect on the reputation of the Company and render ineffective the Company's
national sales and marketing initiatives. In addition, there can be no assurance
that dealers or complementary technologies acquired in the future will achieve
anticipated revenue and earnings. There also can be no assurance that the
existing dealer network will continue to be receptive to the Company's
acquisition program or that dealers which are not acquired by the Company will
adhere to the Company's marketing, training, support and pricing directives. The
occurrence of either of these events would impair the Company's plans to
rationalize its distribution network. See "Business -- Business Strategy."
 
YEAR 2000 COMPLIANCE
 
     The Year 2000 issue relates to whether computer systems will properly
recognize and process information relating to dates in and after the year 2000.
These systems could fail or produce erroneous results if they cannot adequately
process dates beyond the year 1999 and are not corrected. Significant
uncertainty exists in the software industry concerning the potential
consequences that may result from the failure of software to adequately address
the Year 2000 issue.
 
     NON-PROPRIETARY (INTERNAL) SOFTWARE AND HARDWARE.  The Year 2000 issue
creates risk for the Company from unforeseen problems in its own computer
systems and from third parties with which the Company deals nationwide. The
Company has begun to review software and hardware used internally in its support
systems to determine whether such software and hardware is Year 2000 compliant.
In addition, the Company intends shortly to commence a survey of parties with
which it conducts a material amount of business to determine the status of their
Year 2000 compliance programs. The Company's objective is to complete this
review and survey by June 30, 1998, and then develop solutions to any material
date-related deficiencies believed to be present in its computer systems and
systems of its major business partners. The Company intends to implement and
test these solutions prior to any anticipated impact of the Year 2000 issue on
its systems. Because the Company is currently assessing the expense and related
potential effect of Year 2000 compliance on the Company's results of operations,
financial condition and business, it cannot provide any assurance that the
effect will not be material.
 
     PROPRIETARY (EXTERNAL) SOFTWARE.  The Year 2000 issue also creates risk for
the Company from problems that may be experienced by customers of its software.
While the Company believes that 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. The Company 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. If these or other customers
experience significant difficulties as a result of the Year 2000 issue, or if
the Company encounters difficulties in responding in a timely manner to customer
requests to upgrade to
 
                                        6
<PAGE>   7
 
Version 9, there could be a material adverse impact on the Company's results of
operations, financial condition or business. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations -- Year 2000
Compliance."
 
DEPENDENCE ON PRINCIPAL PRODUCTS
 
     The Company currently derives a significant percentage of its revenue from
sales of The Medical Manager core system. As a result, any event adversely
affecting its core product could have a material adverse effect on the Company's
results of operations, financial condition or business. Revenue associated with
existing products could decline as a result of several factors, including price
competition and sales practices. There can be no assurance that the Company will
continue to be successful in marketing its current products or any new or
enhanced products. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and "Business -- Research and Development."
 
DEPENDENCE ON PROPRIETARY SOFTWARE
 
     The Company's success is dependent to a significant extent on its ability
to protect the proprietary and confidential aspects of its software technology.
The Company's software technology is not patented and existing copyright laws
offer only limited practical protection. The Company relies on a combination of
trade secret, copyright and trademark laws, license agreements, nondisclosure
and other contractual provisions and technical measures to establish and protect
its proprietary rights in its products. There can be no assurance that the legal
protections afforded to the Company or the steps taken by the Company will be
adequate to prevent misappropriation of the Company's technology. In addition,
these protections do not prevent independent third-party development of
competitive products or services. The Company believes that its products,
trademarks and other proprietary rights do not infringe upon the proprietary
rights of third parties. There can be no assurance, however, that third parties
will not assert infringement claims against the Company in the future or that
any such assertion will not require the Company to enter into a license
agreement or royalty arrangement with the party asserting the claim. As
competing health care information systems increase in complexity and overall
capabilities and the functionality of these systems further overlap, providers
of such systems may become increasingly subject to infringement claims.
Responding to and defending any such claims may distract the attention of the
Company's management and otherwise have a material adverse effect on the
Company's results of operations, financial condition or business. See
"Business -- Proprietary Rights and Licenses."
 
RISKS RELATED TO TECHNOLOGICAL CHANGE AND NEW PRODUCT DEVELOPMENT
 
     The market for the Company's products is characterized by rapid change and
technological advances requiring ongoing expenditures for research and
development and the timely introduction of new products and enhancements of
existing products. The Company's future success will depend, in part, upon its
ability to enhance its current products, to respond effectively to technological
changes, to sell additional products to its existing client base and to
introduce new products and technologies that address the increasingly
sophisticated needs of its clients. The Company is devoting significant
resources to the development of enhancements to its existing products and the
migration of existing products to new software platforms. There can be no
assurance that the Company will successfully complete the development of new
products or the migration of products to new platforms or that the Company's
current or future products will satisfy the needs of the market for practice
management systems. Further, there can be no assurance that products or
technologies developed by others will not adversely affect the Company's
competitive position or render its products or technologies noncompetitive or
obsolete. See "Business -- Research and Development."
 
LIMITED COMBINED OPERATING HISTORY
 
     The Company has been conducting operations and generating revenues through
the combined efforts of the Founding Companies since the closing of the IPO. The
Company has integrated the operations of these businesses by instituting
Company-wide systems and procedures that are necessary to successfully manage
the combined enterprise on a profitable basis. In addition, the Company has been
assimilating the operations of
                                        7
<PAGE>   8
 
various dealers acquired after the IPO. There can be no assurance that the
Company will continue to be able to integrate the operations of these entities
and others that may subsequently be acquired on a successful and profitable
basis. See "Business -- Business Strategy."
 
POSSIBLE NEED FOR ACQUISITION FINANCING
 
     The Company currently intends to finance future acquisitions by using
shares of its Common Stock for a substantial portion of the consideration to be
paid. In the event that its Common Stock does not maintain a sufficient market
value, or potential acquisition candidates are unwilling to accept Common Stock
as part of the consideration for the sale of their businesses, the Company may
be required to utilize a substantial portion of its available cash resources,
including a portion of the net proceeds from this Offering, in order to maintain
its acquisition program. If the Company does not have sufficient cash resources,
its growth could be limited unless it is able to obtain additional capital
through debt or equity financings. To expand its cash resources, the Company
entered into a $10.0 million line of credit agreement with Barnett Bank of Tampa
on January 14, 1998. The line of credit matures on May 31, 1999. There can be no
assurance that the Company will be able to obtain financing beyond the maturity
date of this line of credit. See "Use of Proceeds" and "Management's Discussion
and Analysis of Financial Condition and Results of Operations -- Liquidity and
Capital Resources."
 
QUALITY ASSURANCE AND PRODUCT ACCEPTANCE CONCERNS
 
     Health care providers demand the highest level of reliability and quality
from their information systems. Although the Company devotes substantial
resources to meeting these demands, its products may, from time to time, contain
errors. Such errors may result in a loss of, or delay in, market acceptance of
its products. Delays or difficulties associated with new product introductions
or product enhancements could have a material adverse effect on the Company's
results of operations, financial condition or business. See
"Business -- Research and Development" and "-- Competition."
 
RISK OF PRODUCT-RELATED CLAIMS
 
     Certain of the Company's products provide applications that relate to
financial records, patient medical records and treatment plans. Any failure of
the Company's products to provide accurate, confidential and timely information,
including failures which may be traceable to the Year 2000 issue, could result
in product liability or breach of contract claims against the Company by its
clients, their patients or others. The Company's products manage and report on
financial data, and any errors in such financial data could result in liability
to the Company. In addition, because the Company's products facilitate
electronic claims submissions, any resulting loss of financial data could result
in liability to the Company. The Company maintains insurance to protect against
such claims, but there can be no assurance that such insurance coverage will be
available or, if available, will adequately cover any claim asserted against the
Company. A successful claim brought against the Company in excess of its
insurance coverage could have a material adverse effect on the Company's results
of operations, financial condition or business. Even unsuccessful claims could
result in the expenditure of funds in litigation, as well as diversion of
management time and resources. There can be no assurance that the Company will
not be subject to product liability or breach of contract claims, that such
claims will not result in liability in excess of its insurance coverage, that
the Company's insurance will cover such claims or that appropriate insurance
will continue to be available to the Company in the future at commercially
reasonable rates.
 
COMPETITION
 
     The market for practice management systems such as The Medical Manager is
highly competitive. The Company's competitors vary in size and in the scope and
breadth of the products and services that they offer. The Company competes with
different companies in each of its target markets. Many of the Company's
competitors have greater financial, development, technical, marketing and sales
resources than the Company. In addition, other entities not currently offering
products and services similar to those offered by the Company, including claims
processing organizations, hospitals, third-party administrators, insurers,
health care organiza-
                                        8
<PAGE>   9
 
tions and others, may enter certain markets in which the Company competes. There
can be no assurance that future competition will not have a material adverse
effect on the Company's results of operations, financial condition or business.
See "Business -- Competition."
 
DEPENDENCE ON KEY PERSONNEL
 
     The Company's operations are dependent on the continued efforts of its
executive officers and the senior management of the Founding Companies, the
Acquired Companies and the Purchased Companies. Furthermore, the Company will
likely be dependent on the senior management of any businesses acquired in the
future. If any of these persons becomes unable or unwilling to continue in his
or her role with the Company, or if the Company is unable to attract and retain
other qualified employees, the Company's business or prospects could be
adversely affected. Although the Company has entered into an employment
agreement, which includes confidentiality and non-compete provisions, with each
of the Company's executive officers, there can be no assurance that any
individual will continue in his present capacity with the Company for any
particular period of time. The success of the Company is also dependent to a
significant degree on its ability to attract, motivate and retain highly skilled
sales, marketing and technical personnel, including software programmers and
systems architects skilled in the computer language with which the Company's
products operate. Competition for such personnel in the software and information
services industries is intense. The loss of key personnel or the inability to
hire or retain qualified personnel could have a material adverse effect on the
Company's results of operations, financial condition or business. Although the
Company has been successful to date in attracting and retaining skilled
personnel, there can be no assurance that the Company will continue to be
successful in attracting and retaining the personnel it requires to successfully
develop new and enhanced products and to continue to grow and operate
profitably. See "Business -- Employees" and "Management."
 
UNCERTAINTY IN HEALTH CARE INDUSTRY; GOVERNMENT HEALTH CARE REFORM PROPOSALS
 
     The health care industry in the United States is subject to changing
political, economic and regulatory influences that may affect the procurement
practices and operations of health care organizations. The Company's products
are designed to function within the structure of the health care financing and
reimbursement system currently being used in the United States. During the past
several years, the health care industry has been subject to increasing levels of
government regulation of, among other things, reimbursement rates and certain
capital expenditures. From time to time, certain proposals to reform the health
care system have been considered by Congress. These proposals, if enacted, may
increase government involvement in health care, lower reimbursement rates and
otherwise change the operating environment for the Company's clients. Health
care organizations may react to these proposals and the uncertainty surrounding
such proposals by curtailing or deferring investments, including those for the
Company's products and services. The Company cannot predict with any certainty
what impact, if any, such proposals or health care reforms might have on its
results of operations, financial condition or business. See
"Business -- Government Regulation."
 
RISK ASSOCIATED WITH GOVERNMENT REGULATION
 
     The United States Food and Drug Administration (the "FDA") has jurisdiction
under the 1976 Medical Device Amendments to the Federal Food, Drug, and Cosmetic
Act (the "FDA Act") to regulate computer products and software as medical
devices if they are intended for use in the diagnosis, cure, mitigation,
treatment or prevention of disease in humans. The FDA has issued a draft policy
statement under which manufacturers of medical image storage devices and related
software are required to submit to the FDA premarket notification applications
(each a "510(k) Application") and otherwise comply with the requirements of the
FDA Act applicable to medical devices. The Company intends to distribute in the
United States a medical image management device (the "Image Module"), which was
cleared by the FDA on April 4, 1997 and is manufactured by a third party in
accordance with specifications set forth in the cleared 510(k) Application.
Prior to marketing the Image Module, the Company will create an interface
between The Medical Manager practice management system and the Image Module. The
Company believes that the addition of its practice management system to the
Image Module does not change the Image Module's intended use or significantly
change the safety or efficacy of the product such that a new 510(k) Application
is
 
                                        9
<PAGE>   10
 
required. The FDA is currently reviewing its policy for the regulation of
computer software and there is a risk that The Medical Manager software could in
the future become subject to some or all of the above requirements, which could
have a material adverse effect on the Company's results of operations, financial
condition or business. See "Business -- Government Regulation."
 
CONTROL BY EXISTING MANAGEMENT AND STOCKHOLDERS
 
     Upon consummation of this Offering, the Company's directors, executive
officers and holders of more than 5% of the Common Stock will beneficially own
approximately 39.2% of the outstanding shares of Common Stock. Although these
persons do not presently have any agreements or understandings to act in
concert, any such agreement or understanding may allow them to exercise control
over the Company's affairs, to dictate the election of the entire Board of
Directors and to control the disposition of any matter submitted to a vote of
stockholders. See "Principal and Selling Stockholders."
 
POTENTIAL ADVERSE MARKET IMPACT OF SHARES ELIGIBLE FOR FUTURE SALE
 
     The market price of the Common Stock may be adversely affected by the sale,
or availability for sale, of substantial amounts of the Common Stock in the
public market. The 2,500,000 shares sold in this Offering will be freely
tradeable unless held by affiliates of the Company. The stockholders of the
Founding Companies received 11,705,470 shares of Common Stock as a portion of
the consideration for the sale of their businesses to the Company. These shares
have not been registered under the Securities Act of 1933, as amended (the
"Securities Act"), and, therefore, may not be sold unless registered under the
Securities Act or sold pursuant to an exemption from registration, such as the
exemption provided by Rule 144. The stockholders who received these shares have
certain demand and piggyback registration rights with respect to these shares.
The Company has also registered 5,000,000 shares of Common Stock which may be
used in connection with future acquisitions. Such shares shall, upon issuance
thereof, be freely tradeable, unless acquired by parties to such acquisitions or
affiliates thereof, other than the issuer, in which case they may be sold
pursuant to Rule 145 under the Securities Act. In addition, resale of these
shares may be contractually restricted.
 
POSSIBLE VOLATILITY OF STOCK PRICE
 
     The market price of the Common Stock may be subject to significant
fluctuations in response to numerous factors, including variations in the annual
or quarterly financial results of the Company or its competitors, changes by
financial research analysts in their estimates of the earnings of the Company,
conditions in the economy in general or in the health care or technology sectors
in particular, announcements of technological innovations or new products or
services by the Company or its competitors, the development of proprietary
rights, unfavorable publicity or changes in applicable laws and regulations (or
judicial or administrative interpretations thereof) affecting the Company or the
health care or technology sectors. Moreover, from time to time, the stock market
experiences significant price and volume volatility that may affect the market
price of the Common Stock for reasons unrelated to the Company's performance.
 
ANTI-TAKEOVER EFFECT OF CERTAIN CHARTER AND BY-LAW PROVISIONS
 
     The Board of Directors of the Company is empowered to issue preferred stock
in one or more series without stockholder action. The existence of this
"blank-check" preferred stock could render more difficult or discourage an
attempt to obtain control of the Company by means of a tender offer, merger,
proxy contest or otherwise. In addition, the Company's Certificate of
Incorporation provides for a classified Board of Directors, which may also have
the effect of inhibiting or delaying a change in control of the Company. Certain
provisions of the Delaware General Corporation Law may also discourage takeover
attempts that have not been approved by the Board of Directors. The Company's
By-laws contain other provisions that may have an anti-takeover effect. See
"Management -- Board Classification" and "Description of Capital Stock."

                                USE OF PROCEEDS
 
     The net proceeds to the Company from the sale of the 1,500,000 shares of
the Common Stock offered by it, after deducting underwriting discounts and
estimated offering expenses, are estimated to be approximately $42.3 million
($48.7 million if the Underwriters' over-allotment option is exercised in full).
The Company will not receive any proceeds from the sale of the 1,000,000 shares
offered by the Selling Stockholders.
 
     The net proceeds to the Company of this Offering are expected to be used to
repay approximately $6.8 million of acquisition-related indebtedness, for
possible future acquisitions and for working capital and other general corporate
purposes. Pending such uses, the net proceeds will be invested in short-term,
interest-bearing, investment grade securities. Of the approximately $6.8 million
of indebtedness to be repaid, $693,000 has an interest rate of 5.85% and is
payable on demand, $6.0 million has an interest rate of 8.25% and is payable in
various installments through January 15, 2000 and $63,000 has an interest rate
of 5.5% and is payable in November 1998.

                                DIVIDEND POLICY
 
     The Company intends to retain all of its earnings to finance the expansion
of its business and for general corporate purposes, including future
acquisitions, and does not anticipate paying any cash dividends on the Common
Stock for the foreseeable future. In addition, the Company's line of credit with
Barnett Bank of Tampa includes restrictions on the ability of the Company to pay
dividends without the consent of the lender.

            UNAUDITED PRO FORMA CONSOLIDATED STATEMENT OF OPERATIONS
 
     The following pro forma financial information reflects the results of MMC,
the Founding Companies, the Acquired Companies and four of the Purchased
Companies, which consist of Companion Technologies of Texas, Companion
Technologies of Florida, Inc., AMSC, Inc., and AMSC Midwest, Inc., for the year
ended December 31, 1997. The results of the other Purchased Companies are not
considered significant and are reflected only subsequent to their respective
acquisition dates.
 
     Certain pro forma adjustments have been made to more accurately reflect the
performance of the Company as if these Purchased Companies and the Founding
Companies had been acquired on January 1, 1997. Such adjustments include, among
other items, the elimination of a write-off of goodwill due to the determination
of impairment, the elimination of restructuring charges taken in connection with
the Company's IPO, reduction in compensation paid to certain stockholders of the
Founding Companies and inclusion of expenses, such as goodwill amortization and
interest expense, resulting from the acquisitions of these Purchased Companies.

could cause future activities and actual results of operations to be materially
different from those set forth in the forward-looking statements. The Company's
actual results may differ due to the factors set forth under the heading "Risk
Factors" or elsewhere in this Prospectus. These factors include, among others,
risks associated with acquisitions, fluctuations in operating results because of
acquisitions, uncertainties relating to the ongoing development of the Company's
software and the Year 2000 issue, variations in stock prices, changes in
government regulations, competition, risk of operations and growth and
integration of newly acquired businesses. Forward-looking information provided
by the Company under the Reform Act should be evaluated in the context of the
foregoing factors and the other information included in this Prospectus. The
Company expressly disclaims any intent or obligation to update these forward
looking statements.
 
     The Company is a leading provider of comprehensive physician management
systems to independent physicians, physician groups, MSOs, IPAs, managed care
organizations, and other providers of health care services in the United States.
The Company's revenue is derived primarily from the licensing of its core
product, The Medical Manager practice management software, the furnishing of
value-added services and the sale of hardware. The Company's primary focus is on
the sale and support of The Medical Manager software and services, while
hardware is sold primarily in response to customer demand. Since the development
of The Medical Manager software in 1982, the Company's installed base has grown
to over 24,000 client sites, representing more than 80 practice specialties,
making it the most widely installed physician practice management software in
the United States.
 
     The Company derives revenue from systems sales, software licensing and
maintenance and other services. Systems sales include sales of The Medical
Manager physician practice management system to new customers, sales of The
Medical Manager system upgrades and add-ons to existing customers, and sales of
The Medical Manager software licenses to independent dealers. Systems sales to
new customers include software licensing, hardware, installation, training, 90
days of software warranty, and varying periods of hardware maintenance,
depending on the warranty of the manufacturer. Systems upgrades and add-ons
include software licensing, peripheral hardware, installation, and training.
Software license sales to independent dealers include software serializations
and other services included in independent dealer agreements. Cost of system
sales reflects the cost of The Medical Manager software, associated hardware,
operating systems, salaries, related benefits, travel and allocations of other
overhead costs.
 
     Maintenance and other revenue includes software and hardware maintenance
contracts, additional training, programming, and sales of additional associated
products and services such as forms, electronic data interchange ("EDI")
services, and other products and services not included in system sales. Software
maintenance represents revenue derived from maintenance agreements, providing
customers with updates and enhancements developed by the Company, and access to
the Company's telephone support centers. Hardware maintenance represents revenue
derived from maintenance agreements for repairs and preventative maintenance to
the hardware. Both hardware and software maintenance are optional to the
customer for smaller installations and required for MSO and larger
installations. Cost of maintenance contracts revenue reflects salaries and
related benefits, travel, and allocations of other overhead costs.
 
     The Company recognizes systems revenue in accordance with the provisions of
the American Institute of Certified Public Accountants ("AICPA") Statement of
Position No. 91-1 "Software Revenue Recognition." Revenue from support and
maintenance contracts is recognized as the services are performed ratably over
the
                                       16
<PAGE>   17
 
contract period, which typically does not exceed one year. Revenue from other
services is recognized as the services are provided. Certain expenses are
allocated between the cost of sales for systems and maintenance and others based
upon management's estimates. Selling, general and administrative expenses
consist primarily of marketing and advertising, salaries and related benefits,
professional fees, administrative costs and allocations of other overhead costs
based on management's estimates.
 
     Research and development expenses represent salaries, related benefits
expenses, and allocations of other overhead costs associated with research and
development activities. Software development costs are included in research and
development and are expensed as incurred. Statement of Financial Accounting
Standards ("SFAS") No. 86 requires the capitalization of certain software
development costs once technological feasibility is established. The capitalized
cost is then amortized over the estimated product life. The period between
achieving technological feasibility and the general availability of such
software is short and software development costs qualifying for capitalization
are insignificant.
 
     As a professional sales and value-added services organization, the Company
responds to the product opportunities and service demands from its clients.
Accordingly, the Company has limited control over the timing and circumstances
under which its products and services are provided. Therefore, the Company can
experience volatility in its operating results from quarter to quarter and year
to year. The operating results for any quarter or year are not necessarily
indicative of the results for any future periods.
 
UNAUDITED PRO FORMA CONSOLIDATED STATEMENT OF OPERATIONS
 
     The pro forma consolidated statement of operations presents the Company as
if the Mergers and the acquisitions of Companion Technologies of Florida, Inc.,
Companion Technologies of Texas, AMSC, Inc. and AMSC Midwest, Inc. occurred on
January 1, 1997. For the thirty-five day period ended February 4, 1997, the date
the Mergers were consummated, the other Founding Companies added $3.1 million in
revenue, $1.4 million of gross profit, and ($0.5) million of net loss. For the
period from January 1, 1997 through each respective acquisition, the included
Purchased Companies contributed $15.0 million of revenue, $6.8 million of gross
profit and ($2.2) million of net loss.
 
     Certain transactions included in the pro forma statements of operations for
the other Founding Companies for the thirty five day period ended February 4,
1997 and for the Purchased Companies included in the pro forma statement of
operations for the period from January 1, 1997 through each respective
acquisition date have been eliminated. In addition, certain adjustments are made
to the pro forma statement of operations to reflect expenses which would have
been incurred by the Company had these acquisitions occurred on January 1, 1997.
These eliminations and adjustments contributed $1.8 million of net income
including the elimination of a loss on impairment of $1.7 million and the
elimination of $0.9 million related to restructuring charges. Adjustments
include an increase in amortization expense of $0.5 million and a net increase
in interest expense of $0.2 million.
 
     As a result, the Company's 1997 pro forma revenue was $96.2 million, total
pro forma gross profit was $49.5 million, and pro forma net income was $10.4
million. Although pro forma revenues and gross profits increased, pro forma net
income decreased $0.8 million. Since the acquisition of these Purchased
Companies, the Company has implemented initiatives to reduce inefficiencies
experienced by these Purchased Companies prior to their acquisition and allow
for benefits related to economies of scale subsequent to the integration of
these acquisitions to be realized in periods subsequent to the acquisition of
these Purchased Companies. No pro forma adjustments have been made to reflect
any improvements to the operating performance of these Purchased Companies after
their respective acquisition dates resulting from efficiencies gained from being
part of the Company as a whole.

</TABLE>
 
     The increase in systems revenue in the year ended December 31, 1997 was
primarily due to the inclusion of the other Founding Companies beginning on
February 5, 1997. For the year ended December 31, 1997, the other Founding
Companies and the Acquired Companies contributed $22.1 million of systems
revenue. The increase in systems sales volume, combined with an increase in the
size of individual systems projects, was a contributing factor in the Company's
systems revenue growth. In addition, overall revenue increased because of the
Company's continued success in marketing to smaller physician groups and sole
practitioners, securing more MSO and large IPA contracts, and through
acquisitions. This success was the result of marketing to new clients,
development of existing clients, and the introduction of new services and
products. Secondly, average overall revenue per client increased primarily
because of the Company's continued success in marketing to MSOs, IPAs and other
larger local clients. The Company's Enterprise Business Group, which
specifically targets national/regional clients, recently obtained contracts with
a total contract price of over $6.8 million, of which $3.5 million was
recognized as income in the year ended December 31, 1997. In addition, for the
year ended December 31, 1997, the acquisitions of the Purchased Companies were
accounted for using the purchase method of accounting. Accordingly, these
acquisitions were included prospectively from their respective purchase dates.
 
     The increase in maintenance and other revenue in the year ended December
31, 1997 was also primarily due to the inclusion of the other Founding
Companies. For the year ended December 31, 1997, the other Founding Companies
and the Acquired Companies contributed $16.2 million to the increase of
maintenance and other revenue. Also, in the year ended December 31, 1997, the
Company recognized approximately $1.5 million in maintenance and other revenue
related to the completion of project-oriented national interface and national
EDI agreements. The Company obtains a maintenance contract for a minimum of one
year with most new systems installed. Therefore, a portion of the Company's
maintenance and other revenue is recognized later than billed. Unearned
maintenance and other revenue as of December 31, 1997 was $4.8 million and will
be recognized in future quarters. The balance of unearned revenues on the
accompanying balance sheet represented customer deposits on systems revenue
projects. Revenue on these projects will be recognized in future periods as the
implementation of the system is completed.
 
     The increase in systems revenue in the year ended December 31, 1996 was
primarily due to additional revenues of $2.7 million generated by the Acquired
Companies. The increase in maintenance and other revenue was primarily due to
additional revenues of $1.5 million generated by the Acquired Companies.

</TABLE>
 
     The increase in systems cost of goods sold in the year ended December 31,
1997 was due to the inclusion of the other Founding Companies beginning on
February 5, 1997. For the year ended December 31, 1997, the other Founding
Companies and the Acquired Companies contributed $9.4 million to the increase of
system cost of goods sold. The increase in maintenance and other was also
primarily due to the inclusion of the other Founding Companies. For the year
ended December 31, 1997, the other Founding Companies and the Acquired Companies
contributed $10.5 million to the increase of maintenance and other cost of goods
sold.
 
     The increase in systems cost of goods sold of $0.8 million in the year
ended December 31, 1996 was primarily due to the associated revenue growth of
the Acquired Companies. The increase in maintenance and other cost of goods sold
was also primarily due to the associated revenue growth of the Acquired
Companies, adding additional costs of $1.5 million. Systems revenue included
sales of licenses, which carry a higher gross profit margin than sales of
systems, primarily due to the inclusion of the costs of equipment and
installation labor in systems sales.
 
     In 1997, the increase in selling, general and administrative expenses was
attributable primarily to the inclusion of the other Founding Companies and the
Purchased Companies. For the year ended December 31, 1997, the other Founding
Companies and the Purchased Companies added $7.9 million of selling, general and
administrative expenses. Also included exclusively in 1997 were the corporate
general and administrative expenses related to common administration of a public
company and acquisition efforts. The increase in selling, general and
administrative expenses of $2.0 million in 1996 was primarily due to the support
of the growth in revenue during 1996.
 
     The increases in research and development expenses of $0.5 million and $0.7
million in the years ended December 31, 1997 and December 31, 1996,
respectively, resulted from investments in new research and development projects
focusing on (i) graphical user interface and relational database technologies
for use in future versions of The Medical Manager software; (ii) significant
enhancements in the development of the Enterprise Manager modules; (iii)
enhancements of an electronic medical records module; and (iv) EDI modules for
focusing on pharmaceutical formularies and laboratories.
 
     Depreciation and amortization expense for the year ended December 31, 1997
increased as a result of the Purchased Companies' acquisitions and the inclusion
of the other Founding Companies. The Purchased Companies were reflected in the
financial statements subsequent to their respective dates of acquisition, all of
which occurred during the year ended December 31, 1997. Thus, depreciation on
the assets acquired with the Purchased Companies was reflected in the year ended
December 31, 1997, while no depreciation expense was reported in the year ended
December 31, 1996 for the Purchased Companies. Additionally, in conjunction with
the acquisition of the Purchased Companies, goodwill approximating $18 million
was recognized. Also, the other Founding Companies had goodwill from
acquisitions prior to the Mergers, contributing approxi-
 
                                       19
<PAGE>   20
 
mately $500,000 in amortization expense in 1997. This goodwill is being
amortized over twenty years subsequent to the acquisition date, all of which is
reflected in the year ended December 31, 1997.
 
     Other income for the year ended December 31, 1997 consisted primarily of
interest revenues earned from the investment of the proceeds from the IPO. Other
expense for the year ended December 31, 1996 included $0.5 million of expense
related to the impairment of an intangible asset at one of the Acquired
Companies.
 
     For the year ended December 31, 1997, income taxes were provided
considering the S corporation status of various acquired entities and the
one-time nonrecurring benefit from the termination of S corporation elections
and the corresponding required adoption of SFAS 109. In addition, the
availability of certain existing corporation deferred tax assets resulted in an
effective tax rate of 33.5%.
 
     The Company's provision for income taxes for the years ended December 31,
1996 and 1995 resulted from those Acquired Companies which were separate C
corporations in those years. MMR&D, the acquiring company at the IPO, had
elected S corporation status and therefore did not provide for corporate federal
income taxes in years 1996 and 1995 since the income passed through and was
taxed at the individual shareholder level.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     The following table sets forth certain selected statements of cash flow
information for the periods presented:

</TABLE>
 
     Substantially all of the cash used in operating activities for the year
ended December 31, 1997 resulted from the increase in accounts receivable of
$6.2 million, the decrease in accounts payable of $2.9 million, and the decrease
of customer deposits and deferred maintenance revenue of $3.0 million. The
increase in accounts receivable was primarily due to the significant growth in
the volume of sales, coupled with an increase in the percentage of sales made to
end-users, which have an extended period of collection as compared to sales to
dealers. The decrease in accounts payable and accrued liabilities included $1.4
million in accounts payable of the other Founding Companies as well as a general
reduction in payable days outstanding for the Acquired Companies and Purchased
Companies. The customer deposits and deferred maintenance revenue decrease of
$3.0 million stemmed primarily from the mergers and acquisitions in the year
ended December 31, 1997. The Purchased Companies and Acquired Companies, on the
date acquired, had customer deposits and deferred maintenance balances $2.5
million greater than at December 31, 1997, relating primarily to the timing of
jobs in progress. In addition, customer deposits decreased by $0.4 million from
December 31, 1996 to December 31, 1997, also the result of timing issues.
 
     For the year ended December 31, 1996, substantially all of the net cash
generated by operating activities resulted from net income, plus an increase of
$1.6 million in customer deposits and deferred maintenance revenue, less an
increase in accounts receivable of $1.1 million. The increase in accounts
receivable in the year ended December 31, 1996 was a result of the revenue
increase. The increase in customer deposits and deferred maintenance liabilities
was primarily the result of a $1.4 million timing difference of jobs in progress
at December 31, 1996 for the Acquired Companies and MMR&D. Investing activities
reflect the substantial completion of the facilities built by MMR&D in the prior
years. Financing activities included dividends paid by MMR&D and other Acquired
Companies to their stockholders.
 
                                       20
<PAGE>   21
 
     The Company generated net income of $5.9 million in the year ended December
31, 1995, which was the primary source of operating cash flow. Cash flows from
investing activities in 1995 reflected cash used to build facilities for MMR&D.
Financing activities cash flows principally included dividends paid by MMR&D and
the other Acquired Companies to their stockholders.
 
     Investing activities included the purchase of fixed assets in the ordinary
course of business and amounts paid for the other Founding Companies and the
Purchased Companies. Amounts paid, net of cash acquired, for the other Founding
Companies was $9.4 million.
 
     Cash flows from financing activities included cash flows from the IPO,
payments of debt acquired from the Founding Companies, Acquired Companies and
Purchased Companies and payments of dividends by MMR&D in 1997 prior to the IPO.
On February 4, 1997, the Company completed the IPO of 6,000,000 shares of Common
Stock, resulting in net proceeds of approximately $58.4 million. Approximately
$46.9 million of the net proceeds were used to pay the cash portion of the
purchase price for the Founding Companies, including $35.0 million paid to the
MMR&D stockholder. Payments on notes payable included the payment, in full, of
the $5.7 million of the assumed debt of the Acquired and Purchased Companies. In
addition, $2.0 million was paid on debt issued in connection with the purchase
of one of the Purchased Companies. Lastly, cash dividends paid by MMR&D and the
Acquired Companies prior to the IPO and their respective purchase dates totaled
$2.4 million.
 
     The Company entered into a $10 million credit line with Barnett Bank of
Tampa and executed the credit line agreement on January 14, 1998. The agreement
contains customary events of default and a number of customary covenants
including certain financial ratios and restrictions on dividends.
 
     The Company's cash and cash equivalents were $6.4 million at December 31,
1997. For purposes of the statement of cash flows, the Company considers all
highly liquid investments with maturity dates of three months or less when
purchased to be cash equivalents. These cash equivalents were predominately in
U.S. dollar domestic tax-free municipal instruments.
 
     The Company believes the net proceeds from the sale of the Common Stock in
this Offering, together with existing cash and cash equivalents and future funds
generated from operations and funds available under its $10 million credit line,
will provide adequate cash to fund its anticipated cash needs at least through
the next twelve months. The Company's cash and cash equivalents are also
available for strategic investment opportunities or other potential cash needs
that may arise in the pursuit of the Company's long-term business strategy.
 
YEAR 2000 COMPLIANCE
 
     The Company is aware of the issues associated with the programming code in
existing computer systems as the next millennium (Year 2000) approaches. The
Year 2000 issue relates to whether computer systems will properly recognize and
process information relating to dates in and after the year 2000. These systems
could fail or produce erroneous results if they cannot adequately process dates
beyond the year 1999 and are not corrected. Significant uncertainty exists in
the software industry concerning the potential consequences that may result from
the failure of software to adequately address the Year 2000 issue.
 
     The Year 2000 issue creates risk for the Company from unforeseen problems
in its own computer systems and from third parties with which the Company deals
nationwide. The Company has begun to review software and hardware used
internally by the Company in all support systems to determine whether they are
Year 2000 compliant. In addition, the Company intends shortly to commence a
survey of parties with which it conducts a material amount of business to
determine the status of their Year 2000 compliance programs. The Company's
objective is to complete this review and survey by June 30, 1998, and then
develop solutions to any material date-related deficiencies believed to be
present in its computer systems and systems of its major business partners. The
Company intends to implement and test these solutions prior to any anticipated
impact of the Year 2000 issue on its systems. Any new software, hardware, or
support systems implemented in the future will be Year 2000 compliant or will
have updates or upgrades or replacements available before the Year 2000
 
                                       21
<PAGE>   22
 
to enable the system to be Year 2000 compliant. Management is currently
assessing the Year 2000 compliance expense and related potential effect on the
Company's earnings.
 
     The Year 2000 issue also creates risk for the Company from problems that
may be experienced by customers of its software. With regard to the Company's
sales of The Medical Manager practice management system, the Company believes
that Version 9 of the system is fully Year 2000 compliant. The Company has
undertaken an extensive campaign to notify its installed customer base of the

these or other customers experience significant difficulties as a result of the
Year 2000 issue, or if the Company 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

INDUSTRY OVERVIEW
 
     Over the past decade, health care costs in the United States have risen
faster than the overall rate of inflation. According to the U.S. Health Care
Financing Administration, health care expenditures have increased from less than
$250 billion, or approximately 9% of U.S. gross domestic product, in 1980 to
over $1.0 trillion, or approximately 15% of U.S. gross domestic product, in
1996. This increase has resulted in broad pressures to reduce costs without
sacrificing the quality of care and has caused significant changes in the health
care industry. While reimbursement for health care has historically been based
on a fee-for-service model of payment, managed care organizations and other
payors are increasingly utilizing alternative reimbursement models that shift
the financial risk of delivering health care from payors to health care
providers, including discounted fee schedules, single payment based on
diagnosis, capitation and other risk sharing arrangements.
 
     The ongoing pressure to contain health care costs and the growing
administrative burdens placed on medical practices have caused physicians to
join together in group practices to share administrative costs and achieve
economies of scale. In addition, other providers and payors are buying and/or
managing physician practices and transforming them into integrated delivery
systems. The Company believes the movement toward group practices has
accelerated the trend toward automation as group practices require greater
efficiency and productivity provided by more powerful practice management
systems. This general increase in the size and complexity of medical practices
has created a greater need for analysis of data and production of timely
management information reports that allow physicians, other providers of medical
care and payors to reach informed conclusions regarding the quality and
appropriateness of various procedures and practices.
 
     The expansion in the number of managed care and third-party payor
organizations, as well as additional governmental regulation and the change in
reimbursement modes, have greatly increased the complexity of pricing practices,
billing procedures and reimbursement policies impacting medical practices.
Practice management systems help providers reduce the costs and improve the
quality of delivering health care services by automating patient care
information systems and administrative processes, ensuring timely access to
relevant information, streamlining the storage and retrieval of information, and
efficiently matching patient needs with available resources. While early systems
concentrated principally on patient billing and collection activities, systems
are now available that record and store clinical information, automate the
processing of insurance and third-party payor claims and integrate the
operations of physician practices with larger health care organizations such as
hospitals, HMOs and MSOs.
 
BUSINESS STRATEGY
 
     The Company's strategy is to build upon its leadership position as the most
widely utilized physician practice management system in the United States. Key
elements of this strategy include:
 
          Capitalizing on National Presence.  Since its IPO, the Company has
     developed a national market presence and centralized client support, and
     has implemented a national retail pricing structure. The Company is a
     vertically-integrated entity that has greater financial strength and
     stability than the individual companies acquired by the Company, which
     allows the Company to compete more effectively on national, regional and
     local levels. The Mergers and subsequent acquisitions have allowed the
     Company to further develop its Enterprise Business Group, a national
     accounts group that assists regional dealers in marketing to, and
     addressing the support needs of, larger provider organizations such as
     IPAs, PPMs, MSOs, and managed care organizations. The Company is also in
     the process of establishing local and regional resource centers, supported
     by centralized corporate and regional operations, including help desks, EDI
     departments and advanced technical and programming personnel. The Company
     expects this structure to result in greater overall consistency and a
     higher level of client support.
 
          Continuing the Consolidation and Rationalization of the Distribution
     Network.  The Company intends to continue the consolidation and
     rationalization of The Medical Manager distribution network which began
     upon the consummation of the IPO. Prior to the 1990s, when independent
     physician practices were most prevalent, the local focus of The Medical
     Manager independent dealer network effectively addressed the practice
     management needs of the market. However, due to the numerous
                                       24
<PAGE>   25
 
     trends in the health care industry toward improved efficiency and cost
     containment, physicians have been forced to consolidate into larger
     practice organizations. To meet the needs of these larger groups, the
     Company has implemented a product distribution strategy that includes the
     acquisition of dealers in major medical communities and large metropolitan
     markets. To date, the Company has acquired 26 independent dealers and
     expects to acquire numerous others. The ownership of these dealers has
     enabled the Company to market more effectively to larger customers while
     assisting the remaining independent dealers in conducting their marketing
     activities. The Company also intends to further standardize the sales and
     support practices of the independent dealers in order to ensure that The
     Medical Manager is sold and supported on a consistent and effective basis.
 
          Increasing Penetration of Management Service Organizations and Other
     Large Physician Groups. The Company will continue to seek to increase its
     sales of enterprise-wide systems, products and services to IPAs, PPMs, MSOs
     and large physician groups. As trends in the health care marketplace
     continue to drive physician affiliations, the Company believes there is
     significant opportunity to increase its share of this rapidly growing
     segment of the practice management market. In order to capitalize on these
     opportunities, the Enterprise Business Group coordinates large group sales
     and support in conjunction with the Company's regional subsidiaries and the
     Company's independent local and regional dealers. In addition, the Company
     has enhanced the functionality of The Medical Manager software to deliver
     increasingly comprehensive physician practice management services in
     enterprise wide settings. With successful sales to such entities as Novant
     Health, Inc., Children's Health System of San Diego, Physiotherapy
     Associates (one of the nation's largest physiotherapy providers), and PHP
     Healthcare Corporation (one of the largest primary care providers in New
     Jersey), the Company has demonstrated its ability to deliver the software
     and services which such large providers demand. The Company believes that
     through continued efforts it can significantly increase its share of this
     market segment.
 
          Cross-Selling Products and Services to Existing Client Base.  The
     Company will continue to aggressively cross-sell additional products and
     services to its existing client base. A majority of the Company's existing
     clients do not currently use The Medical Manager software's entire suite of
     products and services. Because of its substantial installed base of over
     24,000 sites, as well as the modular, integrated product design of The
     Medical Manager software, the Company intends to target many of its
     customers as candidates for cross-selling opportunities, including system
     upgrades, additional software application modules, services such as
     hardware and software maintenance, system and process planning, project
     management, custom programming and EDI capabilities.
 
          Continuing Development of New Products, Product Enhancements and
     Services.  The Company intends to continue its leadership role in the
     development and introduction of new products, product enhancements and
     services for the physician practice marketplace. To do so, the Company
     intends to continue to commit significant financial and human resources to
     its research and development efforts. A key focus of the Company's research
     and development efforts is the further enhancement of The Medical Manager
     software's ability to operate within a variety of integrated delivery
     environments. The Company's strategic development initiatives include
     advanced systems, such as a version of The Medical Manager software
     incorporating relational databases, a graphical user interface and enhanced
     client server applications. The Company develops new products, product
     enhancements and services with input from its physician-clients. For the
     years ended December 31, 1996 and 1997, the Company's expenses for research
     and development were $2.7 million and $3.2 million, respectively,
     representing 8.1% and 4.0% of the Company's revenue for those periods.
 
PRODUCTS
 
     The Medical Manager software is an integrated practice management system
encompassing patient care, clinical, financial and management applications. Due
to its scalable design, The Medical Manager system is a cost-effective solution
in a stand-alone or enterprise-wide environment. The Medical Manager software is
designed to operate on a wide range of hardware platforms, from Intel-based
computer systems for small and medium sized practices, to RISC-based systems,

modular, fully integrated product portfolio allows clients to add incremental
capabilities to
                                       25
<PAGE>   26
 
existing information systems while preserving and minimizing the need for
capital investments. The Company believes that the latest version of The Medical
Manager software, Version 9, is Year 2000 compliant.
 
     The pricing of The Medical Manager system is a function of the number of
modules purchased, the number of users per site, the number of practices, the
operating system and the complexity of the installation. Hardware support and
services are priced separately from software products and are typically
coordinated by the dealer.
 
     The Medical Manager system provides to physician practices a broad range of
patient care and practice management features, including:

     team from the outset, works with the client throughout the life of the
     contract.
 
          Support Services.  A critical element in assuring proper use of and
     satisfaction with the Company's products involves ongoing support services
     provided to the end-users. The Company provides to its clients continuing
     software and hardware support under agreements that typically have a one
     year term. These agreements provide for general support via help desks,
     error corrections to software, remote diagnostics and on-site hardware and
     software technicians. Support services are provided during normal business
     hours and can be expanded to include 24 hour coverage seven days a week. As
     of March 31, 1998, the Company had approximately 400 full-time employees
     devoted to providing support services to its customer base.
 
          Value-Added Services.  The Company advises its enterprise-wide clients
     on how best to bring together disparate physician practices into an
     integrated health care delivery network. The Company works in partnership
     with its client's clinical and administrative management in the areas of
     patient and workflow redesign, job function review and re-education,
     standardization consultation, project engineering, timeline and resource
     management and ongoing relationship management. The Company and many of its
     independent dealers maintain substantial resources capable of providing
     custom programming solutions for a broad range of client requests. Many of
     these solutions may be generated at the regional and local levels using the
     Company's Data Merge language, which allows modifications to be made
     without changing source code.
 
          Training and Continuing Education.  The Company believes initial and
     continuing education are key components in ensuring customer satisfaction
     and retention and, accordingly, has devoted significant resources to its
     Training and Continuing Education Departments. Because The Medical Manager
     system has been in use since 1982, a substantial amount of experience and
     expertise has been gained by the Company's training staff in optimizing
     methodology and curriculum to achieve the best results. Training methods
     include classroom and computer-based training, on-site visits for system
     setup and review and video training tapes available on selected modules.
     The Company also assists its clients in developing their own training
     staff, materials and guidelines. Continuing education programs, a quarterly
     newsletter and user group conferences are sponsored by the Company,
     providing the user with valuable information as well as an opportunity for
     the Company to demonstrate new enhancements and features of the product.
     The Company makes available to clients extensive user documentation and
     reference manuals including, among others, installation guides, advanced
     system manuals, a custom report writer manual and an MSO implementation
     workbook.
 
SALES AND MARKETING
 
     The Company sells its products and services nationally through a direct
sales organization consisting of approximately 150 sales personnel, as well as
through its independent dealer network of approximately 140 dealers. This
distribution effort is responsible for sales to new clients, ranging in size
from solo practitioners to enterprise-wide clients, and follow-up sales of
upgrades and enhancements to existing clients. To enhance the effectiveness of
its sales effort, the Company provides its sales force and independent dealer
network with (i) comprehensive training in the Company's products and services,
(ii) marketing materials, and (iii) ongoing support.
 
                                       31
<PAGE>   32
 
     Small and medium-sized sales, routinely handled by the direct sales force
and independent dealers, generally involve a sales cycle of 30 to 60 days.
Larger sales, managed by the Enterprise Business Group, typically involve a
Request For Proposal process which lengthens the sales cycle to 60 to 90 days or
longer. Hardware and software maintenance agreements are generally renewed on an
annual basis. Standard payment terms are 50% due upon system order with the
balance due upon completion of system installation.
 
     To address the more complex needs of larger clients, the Enterprise
Business Group coordinates the Company's sales effort for large clients (such as
MSOs, IPAs and managed care organizations) and assists in the implementation of
systems and the maintenance of ongoing client relationships. Many of the
independent dealers are experienced in selling to and supporting enterprise wide
clients. The Company intends to continue to utilize the Enterprise Business
Group to assist local and regional dealers in these efforts. At the enterprise-
wide client level, relationship managers work with the client throughout the
contract term to keep informed of customer expectations and help ensure customer
satisfaction.
 
     The Company generates sales leads through referrals from customers and
management consultants, responses to requests for proposals, strategic alliances
with complementary companies, the Company's Internet web sites and associated
links, industry seminars, trade shows, direct telephone and mail campaigns and
advertisements in trade journals.
 
     In order to capitalize on opportunities to cross-sell its products and
services to existing clients, the Company maintains contacts with its clients at
the local, regional and national levels through electronic mail links on its
Internet web sites, monthly and quarterly newsletters, technical updates,
product release bulletins, user meetings, training seminars, industry
conferences and market-specific seminars, such as its MSO User Conference. The
Company also works with certain of its client base on the selection,
implementation, use and benefits derived from the product and publishes these as
Client Profiles, providing both the client and the Company with market exposure
and the opportunity to share successes.
 
     Since 1988, the Company has utilized an educational license of The Medical
Manager physician practice management system to teach office automation within
the medical field. The system has been installed in vocational schools, junior
colleges and universities nationwide. Delmar Publishers Inc., one of the leading
education textbook publishers in the country, markets a student textbook and
instructor's manual for courses that teach computer skills in the medical field,
using The Medical Manager software. Since 1988, more than 600 site licenses of
the educational version have been sold.
 
DISTRIBUTION NETWORK
 
     Prior to the 1990s, when independent physician practices were most
prevalent, the local focus of independent dealers effectively addressed the
practice management needs of the market. However, due to the numerous trends in
the health care industry focusing attention on the delivery of high quality and
cost effective care (as well as the need to demonstrate such quality and
effectiveness), individual physicians and small group practices have been forced
to pool their resources in order to compete effectively. As a result, large
physician organizations have become much more prevalent in the medical
marketplace. To keep pace with the increasingly sophisticated practice
management needs of these larger groups, the independent dealers for The Medical
Manager software have been consolidating in order to build the necessary
technical, service and support resources.
 
     The Company believes that a fundamental and unique strength of The Medical
Manager system is its nationwide dealer network, which currently includes
approximately 140 dealer organizations. The number has been reduced from
approximately 180 at the consummation of the IPO, due to the Company's
acquisition of 26 dealers and the independent consolidation of dealers among
themselves. As a result of the many years of selling and supporting The Medical
Manager product line, the personnel in the Company's dealer network represent a
valuable resource. The Company believes that the continued consolidation and
rationalization of the dealers for The Medical Manager system is a necessary
response to changes in the physician marketplace. The Company's strategy for its
dealer network includes the acquisition of dealers in strategic markets as well
as the rationalization of the remaining independent dealers in order to ensure
that The Medical Manager system is sold and supported on a consistent and
effective basis throughout the dealer network.
                                       32
<PAGE>   33
 
     The Company believes that it has developed a presence in most major medical
communities and metropolitan markets throughout the country. As a result, the
Company's dealer acquisition strategy will continue to focus on acquiring
dealerships that have both a strong presence in key markets and demonstrated
expertise with The Medical Manager product line.
 
     The Company intends to continue to use its existing network of independent
dealers as an integral part of its distribution network for The Medical Manager
system. The Company is instituting a program with its independent dealers to
standardize hardware configurations, client training programs and service levels
developed by the Company. The Company will also provide services to the
independent dealers, many of which are unable to provide such resources as
independent entities. Such services include: (i) dealer training; (ii) help
desks; (iii) advanced technical services, such as custom programming services;
and (iv) sales support for large systems sales from the Enterprise Business
Group.
 
RESEARCH AND DEVELOPMENT
 
     The Company seeks to meet the needs of its clients by continuing to develop
new products and enhancements of existing products. Accordingly, the Company
believes that continued leadership in the practice management systems industry
will require significant additional commitments of resources to research and
development. The Company maintains its research and development campus in
Alachua, Florida, where development of The Medical Manager software began in
1981. As of March 31, 1998, the Company had approximately 110 employees engaged
primarily in its research and development efforts.
 
     The Company's research and development activities involve Company personnel
as well as physicians, physician practice staffs and leading health care
institutions. The Company's research and development efforts continue the
tradition of The Medical Manager system being a leader in product innovation, as
indicated by the following:
 
     -  In 1982, The Medical Manager software was first installed.
 
     -  In 1985, The Medical Manager Electronic Media Claims module was
        released.
 
     -  In 1987, The Medical Manager software became the first practice
        management system to perform electronic claims submission in all 50
        states.
 
     -  In 1988, The Medical Manager Report Writer module was released.
 
     -  In 1990, The Medical Manager Data Merge Language module, was released,
        allowing unlimited customization within The Medical Manager software

     -  In January 1991, The Medical Manager Electronic Remittance module was
        released.
 
     -  In June 1991, The Medical Manager software became the first practice

        partners.
 
     -  In 1992, The Medical Manager software became the first practice
        management system to introduce electronic interfaces to laboratory
        systems.
 
     -  In 1994, The Medical Manager Managed Care module was announced.
 
     -  In January 1995, The Medical Manager Quality Care Guidelines module was

                                       33
<PAGE>   34
 
     -  In July 1997, The Medical Manager Patient Flow Tracking, Advanced
        Appointment Search (MultiResource) and Laser Form Generator modules were
        released.
 
     -  In September 1997, The Medical Manager Medical Records System was
        released.
 
     -  In February 1998, The Medical Manager Patient Advisory System was
        released.
 
     A key goal of current research and development efforts involves adapting
The Medical Manager system to operate more effectively within integrated
delivery environments. To achieve this goal, the Company is pursuing a strategic
development initiative directed toward the development of advanced health care
information systems that include a relational database, graphical user
interfaces and enhanced client-server applications. Current focus areas for new
product development and enhancement include the following:
 
  ENTERPRISE SYSTEM
 
     The Company intends to develop an increasing number of automation tools to
support the growing number of integrated health care delivery systems across the
nation. Developments within The Medical Manager's MSO Enterprise System are
expected to include enterprise appointment and resource scheduling and
enterprise communications. In addition, further developments in The Medical
Manager software's connectivity engines should continue to promote the open
exchange of information between medical institutions.
 
  MANAGED CARE
 
     Physicians realize that sophisticated health care automation systems are
required to support managed care, compete for capitated contracts and contain
healthcare costs while providing effective, high quality care. Development
efforts within the Managed Care module are expected to result in a product that
provides referral outcome reporting that can perform outcome analysis across
multiple practices within the provider network. As managed care matures, new
markets will be created that require the support of automation. Development
efforts within the Managed Care module will be designed to support the evolving
subcapitation market by allowing primary care groups to receive the total
capitation payment from a payor and allocate the capitation payment among
contracted specialists for services they have provided.
 
  CLINICAL APPLICATIONS
 
     The Company recognizes that improvements in the technology that supports
the gathering, storing, retrieving and reporting of clinical data and the
creation of a sophisticated computerized patient record system are critical to
the enhancement and improvement of health care delivery across the nation. As a
result, the Company is engaged in efforts to rapidly develop fully-integrated
components of a computerized patient record containing functionality and
knowledge bases that support the way physicians provide health care services.
Research and analysis of various input technologies and devices continue with
the goal of providing physicians with usable tools that will allow them to
effectively gather and use clinical data at the point-of-care.
 
  GRAPHICAL USER INTERFACE
 
     The Company's graphical user interface is currently under development. The
Company's development efforts are intended to produce a product that will
support users opting to install technology to support a Windows environment.
 
PROPRIETARY RIGHTS AND LICENSES
 
     The Company relies on a combination of trade secret, copyright and
trademark laws, license agreements, nondisclosure and other contractual
provisions and technical measures to establish and protect its proprietary
rights in its products. The Company distributes its products under software
license agreements that grant clients a nonexclusive, nontransferable license to
the Company's products and contain terms and conditions prohibiting the
unauthorized reproduction or transfer of the Company's products. In addition,
the Company
 
                                       34
<PAGE>   35
 
attempts to protect its trade secrets and other proprietary information through
agreements with employees and consultants. Substantially all current employees
involved in product development have signed an assignment of inventions
agreement. There can be no assurance that the legal protections afforded to the
Company or the precautions taken by the Company will be adequate to prevent
misappropriation of the Company's technology. In addition, these protections do
not prevent independent third-party development of functionally equivalent or
superior technologies, products or services. Any infringement or
misappropriation of the Company's proprietary software could disadvantage the
Company in the efforts to attract and retain new clients in a highly competitive
market and could cause the Company to lose revenues or incur substantial
litigation expense. The Company believes that, due to the rapid pace of
innovation within the software industry, factors such as the technological and
creative skills of its personnel and ongoing reliable product maintenance and
support are more important in establishing and maintaining a leadership position
within the industry than are the various legal protections afforded to its
technology.
 
GOVERNMENT REGULATION
 
     The FDA has jurisdiction under the FDA Act to regulate computer products
and software as medical devices if they are intended for use in the diagnosis,
cure, mitigation, treatment or prevention of disease in humans. The FDA is
currently reviewing its policy for the regulation of computer software and there
is a risk that The Medical Manager software could in the future become subject
to regulation by the FDA, which could have a material adverse effect on the
Company's results of operations, financial condition or business. Currently, the
Company believes that The Medical Manager software would not be subject to FDA
regulation requiring registration, listing, premarket notification or approval
and adherence with device good manufacturing practices or medical device
reporting requirements.
 
     The FDA has issued a draft policy statement relating to picture archiving
and communications systems that requires manufacturers of medical image storage
devices and related software to submit to the FDA 501(k) Applications and
otherwise comply with the requirements of the FDA Act applicable to medical
devices. The Company intends to distribute in the United States, the Image
Module, which was cleared by the FDA on April 4, 1997 and is manufactured by a
third party in accordance with specifications set forth in the cleared 510(k)
Application. Prior to marketing the Image Module, the Company will create an
interface between The Medical Manager practice management system and the Image
Module. The Company believes that the addition of its practice management system
to the Image Module does not change the Image Module's intended use or
significantly change the safety or efficacy of the product such that a new
510(k) Application is required under applicable federal regulations.
 
COMPETITION
 
     The market for physician practice management systems and services is highly
competitive. The Company believes that the principal competitive factors in this
market include the functionality and price of the practice management system,
the support provided to system users, ongoing research and development efforts
and the national presence and financial stability of the system. The industry is
fragmented and includes numerous competitors. The Company believes its principal
competitive advantages are the product's substantial installed client base, open
system design and the advanced features and capabilities, as well as the
Company's focus on customer support and training programs and its network of
dealers. The Company's principal competitors include other physician practice
management system companies, local software companies and other companies that
provide information systems to health care providers. Certain of the Company's
competitors have greater financial, development, technical, marketing and sales
resources than the Company. In addition, as the market for the Company's
products develops, additional competitors may enter the market and competition
may intensify.
 
EMPLOYEES
 
     At March 31, 1998, the Company had 939 employees. No employees are covered
by any collective bargaining agreements. The Company considers its relationships
with its employees to be good.
 
                                       35

FACILITIES
 
     The Company's principal corporate offices are located at 3001 North Rocky
Point Drive East, Tampa, Florida. The Company's research and support facilities
are located in Alachua, Florida. The Company also maintains national sales and
support offices in Mountain View, California, and has 59 additional offices in
various regions of the country.
 
     The Company owns three of its facilities and leases the remainder of its
facilities. The leases have remaining terms ranging from one to five years. The
Company believes that its current facilities, together with a facility which it
plans to lease by December 31, 1998, are adequate for its current and
foreseeable needs and that suitable additional space will be available as
required.

                          DESCRIPTION OF CAPITAL STOCK
 
GENERAL
 
     The Company's authorized capital stock consists of 50,000,000 shares of
Common Stock, par value $0.01 per share, and 500,000 shares of undesignated
preferred stock, par value $0.01 per share (the "Preferred Stock").
 
     The following statements are brief summaries of certain provisions with
respect to the Company's capital stock contained in its Certificate of
Incorporation (the "Certificate of Incorporation") and the Amended and Restated
By-laws and are qualified in their entirety by reference thereto.
 
COMMON STOCK
 
     The holders of shares of Common Stock are entitled to one vote for each
share held of record on all matters voted upon by stockholders, including the
election of directors. The Certificate of Incorporation does not provide for
cumulative voting, and, accordingly, the holders of a majority of the shares of
Common Stock entitled to vote in any election of directors may elect all of the
directors standing for election. Subject to the rights of any then outstanding
shares of Preferred Stock, the holders of the Common Stock are entitled to such
dividends as may be declared in the discretion of the Board of Directors out of
funds legally available therefor. Holders of Common Stock are entitled to share
ratably in the net assets of the Company upon liquidation after payment or
provision for all liabilities and any preferential liquidation rights of any
Preferred Stock then outstanding. The holders of shares of Common Stock have no
preemptive rights to purchase shares of stock of the Company. Shares of Common
Stock are not subject to any redemption provisions and are not convertible into
any other securities of the Company. All outstanding shares of Common Stock are,
and the shares of Common Stock to be issued pursuant to this Offering will be
upon payment therefor, fully paid and nonassessable.
 
     The Common Stock trades on the Nasdaq National Market under the symbol
"MMGR."
 
PREFERRED STOCK
 
     The Preferred Stock may be issued from time to time by the Board of
Directors in one or more series. Subject to the provisions of the Certificate of
Incorporation and limitations prescribed by law, the Board of Directors is
expressly authorized to adopt resolutions to issue the shares, to fix the number
of shares and to change the number of shares constituting any series and to
provide for or change the voting powers, designations, preferences and relative,
participating, optional or other special rights, qualifications, limitations or
restrictions thereof, including dividend rights (including whether dividends are
cumulative), dividend rates, terms of redemption (including sinking fund
provisions), redemption prices, conversion rights and liquidation preferences of
the shares constituting any series of the Preferred Stock, in each case without
any further action or vote by the stockholders. The Company has no current plans
to issue any shares of Preferred Stock.
 
     One of the effects of undesignated Preferred Stock may be to enable the
Board of Directors to render more difficult or to discourage an attempt to
obtain control of the Company by means of a tender offer, proxy contest, merger
or otherwise, and thereby to protect the continuity of the Company's management.
The issuance of shares of the Preferred Stock pursuant to the Board of
Directors' authority described above may adversely affect the rights of the
holders of Common Stock. For example, Preferred Stock issued by the Company may
rank prior to the Common Stock as to dividend rights, liquidation preference or
both, may have full or limited voting rights and may be convertible into shares
of Common Stock. Accordingly, the issuance of shares of Preferred Stock may
discourage bids for the Common Stock or may otherwise adversely affect the
market price of the Common Stock.
 
STATUTORY BUSINESS COMBINATION PROVISION
 
     The Company is subject to the provisions of Section 203 ("Section 203") of
the Delaware General Corporation Law ("DGCL"). Section 203 provides, with
certain exceptions, that a Delaware corporation may not engage in any of a broad
range of business combinations with a person or an affiliate or associate of
such person who is an "interested stockholder" for a period of three years from
the date that such person became an
 
                                       41
<PAGE>   42
 
interested stockholder unless: (i) the transaction resulting in a person
becoming an interested stockholder, or the business combination, is approved by
the Board of Directors of the corporation before the person becomes an
interested stockholder; (ii) the interested stockholder acquired 85% or more of
the outstanding voting stock of the corporation in the same transaction that
makes such person an interested stockholder (excluding shares owned by persons
who are both officers and directors of the corporation, and shares held by
certain employee stock ownership plans); or (iii) on or after the date the
person becomes an interested stockholder, the business combination is approved
by the corporation's board of directors and by the holders of at least 66% of
the corporation's outstanding voting stock at an annual or special meeting,
excluding shares owned by the interested stockholder. Under Section 203, an
"interested stockholder" is defined as any person who is (i) the owner of 15% or
more of the outstanding voting stock of the corporation or (ii) an affiliate or
associate of the corporation and who was the owner of 15% or more of the
outstanding voting stock of the corporation at any time within the three-year
period immediately prior to the date on which it is sought to be determined
whether such person is an interested stockholder.
 
     The Company's stockholders, by adopting an amendment to the Certificate of
Incorporation, may elect not to be governed by Section 203, which election would
be effective 12 months after such adoption. The provisions of Section 203 could
delay or frustrate a change in control of the Company, deny stockholders the
receipt of a premium on their Common Stock and have an adverse effect on the
Common Stock. The provisions also could discourage, impede or prevent a merger
or tender offer, even if such event would be favorable to the interests of
stockholders.
 
LIMITATIONS ON DIRECTORS' LIABILITIES AND INDEMNIFICATION
 
     Limitation on Liability.  Pursuant to the Certificate of Incorporation and
as permitted by Section 102(b)(7) of the DGCL, directors of the Company are not
liable to the Company or its stockholders for monetary damages for breach of
fiduciary duty, except for liability in connection with a breach of duty of
loyalty, for acts or omissions not in good faith or that involve intentional
misconduct or a knowing violation of law, for dividend payments or stock
repurchases that are illegal under Delaware law or for any transaction in which
a director has derived an improper personal benefit.
 
     Indemnification.  To the maximum extent permitted by law, the Certificate
of Incorporation provides for mandatory indemnification of directors and
officers of the Company against any expense, liability and loss to which they
become subject, or which they may incur as a result of having been a director or
officer of the Company. In addition, the Company must advance or reimburse
directors and officers for expenses incurred by them in connection with certain
claims.
 
POTENTIAL ANTI-TAKEOVER EFFECT OF CERTAIN PROVISIONS OF THE CERTIFICATE OF
INCORPORATION AND BY-LAWS
 
     The Certificate of Incorporation and the Amended and Restated By-laws
contain provisions that could have an antitakeover effect. The provisions are
intended to enhance the likelihood of continuity and stability in the
composition of the Board of Directors and in the policies formulated by the
Board of Directors. These provisions also are intended to help ensure that the
Board of Directors, if confronted by an unsolicited proposal from a third party
which has acquired a block of stock of the Company, will have sufficient time to
review the proposal and appropriate alternatives to the proposal and to act in
what it believes to be the best interest of the stockholders.
 
     The following is a summary of such provisions in the Certificate of
Incorporation and the Amended and Restated By-laws. The Board of Directors has
no current plans to formulate or effect additional measures that could have an
antitakeover effect.
 
     Classified Board of Directors.  The Certificate of Incorporation provides
for a Board of Directors divided into three classes of directors serving
staggered three-year terms. The classification of directors has the effect of
making it more difficult for stockholders to change the composition of the Board
of Directors in a relatively short period of time. At least two annual meetings
of stockholders, instead of one, generally will be required to effect a change
in a majority of the Board of Directors. Such a delay may help ensure that the
Board of Directors and the stockholders, if confronted with an unsolicited
proposal by a stockholder attempting to force
                                       42
<PAGE>   43
 
a stock repurchase at a premium above market, a proxy contest or an
extraordinary corporate transaction, will have sufficient time to review the
proposal and appropriate alternatives to the proposal and to act in what it
believes to be the best interest of the stockholders. Directors, if any, elected
by holders of the Preferred Stock voting as a class, will not be classified as
aforesaid. Moreover, under Delaware law, in the case of a corporation having a
classified board, stockholders may remove a director only for cause. This
provision will preclude the stockholders from removing incumbent directors
without cause.
 
     Advance Notice Requirements for Director Nominees.  The Amended and
Restated By-laws establish an advance notice procedure with regard to the
nomination of candidates for election as directors at any meeting of
stockholders called for the election of directors. The procedure provides that a
notice relating to the nomination of directors must be timely given in writing
to the Secretary of the Company prior to the meeting. To be timely, notice
relating to the nomination of directors must be delivered not less than 90 days
prior to any annual meeting or 10 days following notice to the stockholder of
any special meeting called for the election of directors.
 
     Notice to the Company from a stockholder who proposes to nominate a person
at a meeting for election as a director must be accompanied by each proposed
nominee's written consent and contain the name, address and principal occupation
of each proposed nominee and other information that may be required under the
proxy rules of the Commission. Such notice must also contain the total number of
shares of capital stock of the Company that will be voted for each of the
proposed nominees, the name and address of the notifying stockholder and the
number of shares of capital stock of the Company owned by the notifying
stockholder.
 
     The presiding officer of a meeting of stockholders may determine that a
person is not nominated in accordance with the nomination procedure, in which
case such person's nomination will be disregarded. Nothing in the nomination
procedure will preclude discussion by any stockholder of any nomination properly
made or brought before any meeting called for the election of directors in
accordance with the above-mentioned procedures.
 
TRANSFER AGENT AND REGISTRAR
 
     The Transfer Agent and Registrar for the Common Stock is American Stock
Transfer and Trust Company.

</TABLE>
 
     The Underwriting Agreement provides that the obligations of the several
Underwriters to purchase and accept delivery of the shares of Common Stock
offered hereby are subject to the approval by their counsel of certain legal
matters and to certain other conditions. The Underwriters are obligated to
purchase and accept delivery for all the shares of Common Stock offered hereby
(other than those shares of the Common Stock covered by the over-allotment
option described below) if any are purchased.
 
     The Underwriters initially propose to offer the shares of Common Stock in
part directly to the public at the initial public offering price set forth on
the cover page of this Prospectus and in part to certain dealers (including the
Underwriters) at such price less a concession not in excess of $0.90 per share.
The Underwriters may allow, and such dealers may re-allow, to certain other
dealers a concession not in excess of $0.10 per share. After the initial
offering of the Common Stock, the public offering price and other selling terms
may be changed by the Representatives at any time without notice.
 
     The Company and the Selling Stockholders have granted to the Underwriters
an option, exercisable for 30 days from the date of this Prospectus, to purchase
up to 375,000 additional shares of Common Stock at the price set forth on the
cover page of this Prospectus less underwriting discounts and commissions. The
Underwriters may exercise such option solely to cover over-allotments, if any,
made in connection with the Offering. To the extent that the Underwriters
exercise such option, each of the Underwriters become obligated, subject to
certain conditions, to purchase its pro rata portion of such additional shares
based on such Underwriter's percentage underwriting commitment in the preceding
table.
 
     The Company and the Selling Stockholders have agreed to indemnify the
Underwriters against certain liabilities, including liabilities under the
Securities Act, or to contribute to payments that the Underwriters may be
required to make in respect thereof.
 
     Each of the Company, its executive officers and directors and the Selling
Stockholders has agreed, subject to certain exceptions, not to (i) offer,
pledge, sell, contract to sell, sell any option or contract to purchase,
purchase any option or contract to sell, grant any option, right or warrant to
purchase or otherwise transfer or dispose of, directly or indirectly, any shares
of Common Stock or any securities convertible into or exercisable or
exchangeable for Common Stock or (ii) enter into any swap or other arrangement
that transfers all or a portion of the economic consequences associated with the
ownership of any Common Stock (regardless of whether any of the transactions
described in clause (i) or (ii) is to be settled by the delivery of Common
Stock, or such other securities, in cash or otherwise) for a period of 90 days
after the date of this Prospectus without the prior written consent of DLJ. In
addition, during such period, the Company has also agreed, subject to certain
exceptions, not to file any registration statement with respect to, and each of
its executive officers, directors and certain stockholders of the Company
(including the Selling Stockholders) has agreed not to make any demand for, or
exercise any right with respect to, the registration of any shares of
 
                                       44
<PAGE>   45
 
Common Stock or any securities convertible into or exercisable or exchangeable
for Common Stock without DLJ's prior written consent.
 
     Other than in the United States, no action has been taken by the Company,
the Selling Stockholders or the Underwriters that would permit a public offering
of the shares of Common Stock offered hereby in any jurisdiction where action
for that purpose is required. The shares of Common Stock offered hereby may not
be offered or sold, directly or indirectly, nor may this Prospectus or any other
offering material or advertisements in connection with the offer and sale of any
such shares of Common Stock be distributed or published in any jurisdiction,
except under circumstances that will result in compliance with the applicable
rules and regulations of such jurisdiction. Persons into whose possession this
Prospectus comes are advised to inform themselves about and to observe any
restrictions relating to the offering of the Common Stock and the distribution
of this Prospectus. This Prospectus does not constitute an offer to sell or a
solicitation of an offer to buy any shares of Common Stock offered hereby in any
jurisdiction in which such an offer or a solicitation is unlawful.
 
     The Underwriters and dealers may engage in passive market making
transactions in the Common Stock in accordance with Rule 103 of Regulation M
promulgated by the Commission. In general, a passive market maker may not bid
for or purchase shares of Common Stock at a price that exceeds the highest
independent bid. In addition, the net daily purchases made by any passive market
maker generally may not exceed 30% of its average daily trading volume in the
Common Stock during a specified two month prior period, or 200 shares, whichever
is greater. A passive market maker must identify passive market making bids as
such on the Nasdaq electronic inter-dealer reporting system. Passive market
making may stabilize or maintain the market price of the Common Stock above
independent market levels. Underwriters and dealers are not required to engage
in passive market making and may end passive market making activities at any
time.
 
     In connection with the offering, the Underwriters may engage in
transactions that stabilize, maintain or otherwise affect the price of the
Common Stock. Specifically, the Underwriters may overallot the offering,
creating a syndicate short position. The Underwriters may bid for and purchase
shares of Common Stock in the open market to cover such syndicate short position
or to stabilize the price of the Common Stock. These activities may stabilize or
maintain the market price of the Common Stock above independent market levels.
The Underwriters are not required to engage in these activities, and may end any
of these activities at any time.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors
Medical Manager Corporation
 
     We have audited the consolidated financial statements of Medical Manager
Corporation listed in the index on page F-1. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Medical Manager
Corporation as of December 31, 1997 and 1996 and the consolidated results of
their operations and their cash flows for each of the three years in the period
ended December 31, 1997 in conformity with generally accepted accounting
principles.

                          MEDICAL MANAGER CORPORATION
 
                 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
 
1.   ORGANIZATION AND BASIS OF PRESENTATION
 
     Medical Manager Corporation ("MMC") was founded on July 10, 1996 to bring
together the research and development, sales, marketing and support resources
for The Medical Manager software, a leading physician practice management system
for independent physicians, physician groups, management service organizations
("MSOs"), Physician Practice Management companies ("PPMs"), independent practice
associations ("IPAs"), managed care organizations and other providers of health
care services in the United States. On February 4, 1997 MMC acquired ("the
Mergers") simultaneously with the closing of its initial public offering of
common stock ("the IPO") five companies (the "Founding Companies"): Medical
Manager Research & Development, Inc. (formerly Personalized Programming, Inc.)
("MMR&D"), Medical Manager Sales & Marketing, Inc. (formerly Systems Plus, Inc.)
("MMS&M"), Medical Manager Southeast, Inc. (formerly National Medical Systems,
Inc.) ("MMSE"), Medical Manager Northeast, Inc. (formerly RTI Business Systems,
Inc.) ("MMNE") and Medical Manager Midwest, Inc. (formerly Systems Management,
Inc.) ("MMMW"). All outstanding shares of the Founding Companies' capital stock
were converted into shares of MMC Common Stock concurrently with the
consummation of the IPO. The aggregate consideration paid by MMC for the
Founding Companies was approximately $46.9 million in cash and 11.7 million
shares of Common Stock of MMC for an aggregate value of $175.7 million. The
acquisitions were accounted for as a combination of the Founding Companies at
historical cost for accounting purposes. MMR&D is identified as the acquirer for
financial statement presentation purposes and is presented on a combined basis
with MMC from July 10, 1996. MMC conducted no significant operations and
generated no revenue prior to the closing of the IPO.
 
     Subsequent to the consummation of the IPO, MMC and the Founding Companies
executed and closed agreements to acquire the following resellers of The Medical
Manager software (the "Acquired Companies"): (i) The Computer Clinic, Inc. and
its affiliates ("Computer Clinic") based in Valhalla, New York; (ii) Adaptive
Health Systems of Washington, Inc. ("Adaptive Health") based in Federal Way,
Washington; (iii) LSM Computing, Inc. ("LSM") based in Somerville, New Jersey;
(iv) Specialized Systems, Inc. ("SSI") based in Van Nuys, California; (v)
Treister-Thorne, Inc. d/b/a Advanced Medical Management, Inc. ("AMM") based in
Houston, Texas; (vi) UNICO, Inc. ("UNICO") based in Evansville, Indiana; (vii)
Medysis, Inc. based in Fort Wayne, Indiana; (viii) Computers for Medicine
Corporation and Carecom, Inc. ("C4M") based in Englewood, Colorado; (ix)
Unisource Systems, Inc. ("Unisource") based in Corpus Christi, Texas; and (x)
CompRx Systems Corporation ("CompRx") based in Hauppauge, New York. All of the
acquisitions of the Acquired Companies closed during the year ended December 31,
1997 and were accounted for using the pooling of interests method of accounting.
The aggregate consideration paid for the Acquired Companies consisted of
1,644,836 shares of Common Stock.
 
     Also subsequent to the consummation of the IPO, MMC and the Founding
Companies executed and closed definitive agreements to acquire substantially all
of the assets or all of the outstanding equity securities of the following
resellers of The Medical Manager software (the "Purchased Companies"): (i)
Artemis, Inc. based in Indianapolis, Indiana, on July 30, 1997; (ii) Boston
Computer Systems, Inc. based in Norwood, Massachusetts, on August 6, 1997; (iii)
Package Computer Systems, Inc. d/b/a PAC-COMP based in Sterling Heights,
Michigan, on August 1, 1997; (iv) Matrix Computer Consultants, Inc. based in
Norman, Oklahoma, on September 5, 1997; (v) Professional Management Systems,
Inc. based in St. Charles, Illinois, on September 10, 1997; (vi) AMSC, Inc.
based in Orlando, Florida, together with its wholly-owned subsidiary, AMSC
Midwest, Inc. based in Topeka, Kansas, on September 11, 1997; (vii) Data
Concepts, Inc. based in Boise, Idaho, on October 30, 1997; (viii) Medical
Systems Consultants, Inc. based in Boise, Idaho, on October 30, 1997; (ix)

on December 31, 1997; and (xii) Companion Technologies of Texas based in
Arlington, Texas, on December 31, 1997. All of the acquisitions of the Purchased
Companies were accounted for using the purchase method of accounting. The

         NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
aggregate consideration paid for the Purchased Companies was 380,230 shares of
Common Stock and $4,265,866 in cash and the issuance of $6,000,000 in debt.
 
     MMC, the Founding Companies, the Acquired Companies, and the Purchased
Companies are referred to collectively as the Company.
 
2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     Basis of Presentation.  The accompanying financial statements have been
presented on a consolidated basis for the year ended December 31, 1997. The
consolidated financial statements include MMC and its wholly owned subsidiaries.
All significant intercompany balances and intercompany transactions have been
eliminated in consolidation. The accompanying consolidated financial statements
include MMC, MMR&D and the Acquired Companies through February 4, 1997, the date
of MMC's acquisition of the Founding Companies, after which the historical
financial statements reflect the results of MMC, MMR&D, the Acquired Companies,
and the other Founding Companies. The results of the Purchased Companies are
reflected as of their respective acquisition dates.
 
     The accompanying financial statements have been presented on a consolidated
basis for the years ended December 31, 1996 and 1995. The financial statements
of MMR&D have been presented on a consolidated basis with those of MMC from July
10, 1996 and with those of the Acquired Companies from January 1, 1995. As
discussed in Note 1, following the close of business of February 4, 1997, MMR&D
merged into a subsidiary of MMC upon consummation of the initial public offering
of the common stock of MMC. MMR&D is identified as the accounting acquirer.
Subsequent to the Offering, the Acquired Companies which were accounted for
under the pooling of interests method of accounting. The accompanying
consolidated financial statements have been adjusted retroactively to show the
effect of the recapitalization and the acquisition of the Acquired Companies as
if they had occurred on January 1, 1995.
 
     Revenue Recognition.  Revenue from software licenses is recognized upon
sale and shipment. Revenue from the sale of systems is recognized when the
system has been installed and when the related client training has been
completed. Amounts billed in advance of installation and pending completion of
remaining significant obligations are deferred. Revenue from support and
maintenance contracts is recognized as the services are performed ratably over
the contract period, which typically does not exceed one year. Revenue from
other services is recognized as they are provided. Certain expenses are
allocated between the cost of sales for systems and sales of maintenance and
other based upon revenue, which basis management believes to be reasonable.
 
     Goodwill and Other Intangibles.  Goodwill and other intangibles consist of
covenants not to compete and goodwill arising from business acquisitions,
detailed as follows (in thousands):
 
<TABLE>
<S>                                                          <C>
Goodwill arising from business acquisitions...............   $24,523
Covenants not to compete..................................       227
                                                             -------
Total gross goodwill and other intangibles................    24,750
Accumulated amortization..................................       975
                                                             -------
Total net goodwill and other intangibles..................   $23,775
                                                             =======
</TABLE>
 
     The covenants not to compete are being amortized over a period of two years
and the goodwill arising from business acquisitions is being amortized over a
twenty year period.
 
     Property and Equipment.  Property and equipment are stated at cost.
Additions and major renewals are capitalized. Repairs and maintenance are
charged to expense as incurred. Upon disposal, the related cost and accumulated
depreciation are removed from the accounts, with the resulting gain or loss
included in income.

<PAGE>   55
                          MEDICAL MANAGER CORPORATION
 
         NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
Depreciation is provided principally on accelerated methods over the estimated
useful lives of the assets. Amortization of leasehold improvements is provided
for over the shorter of the estimated service life of the leased asset or the
lease term using the straight-line method.
 
     Inventory.  Inventory primarily consists of peripheral computer equipment.
Inventory cost is accounted for on the first-in, first-out basis and reported at
the lower of cost or market.
 
     Research and Development.  Software development costs are included in
research and development and are expensed as incurred. SFAS No. 86, Accounting
for the Costs of Computer Software to be Sold, Leased, or Otherwise Marketed,
requires the capitalization of certain software development costs once
technological feasibility is established. The capitalized cost is then amortized
over the estimated product life. To date, the period between achieving
technological feasibility and the general availability of such software has been
short and software development costs qualifying for capitalization have been
insignificant.
 
     Cash and Cash Equivalents.  The Company considers all highly liquid
investments with maturity dates of three months or less when purchased to be
cash equivalents.
 
     Income Taxes.  The Company utilizes the asset and liability method of
accounting for income taxes. Under this method, deferred income taxes are
recorded to reflect the tax consequences on future years differences between the
tax basis of assets and liabilities and their financial reported amounts at each
year end based on enacted laws and statutory rates applicable to the periods in
which differences are expected to affect taxable income. A valuation allowance
is provided against the future benefits of deferred tax assets if it is
determined that it is more likely than not that the future tax benefits
associated with the deferred tax asset will not be realized. See Note 12.
 
     Use of Estimates.  The preparation of financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenue and expenses during
the reported period. Actual results could differ from those estimates; however,
management does not believe these differences would have a material effect on
operating results.
 
     Asset Impairment.  SFAS No. 121, Accounting for the Impairment of
Long-Lived Assets and for Long Lived Assets to be Disposed Of, effective for
years beginning after December 15, 1995, requires that long-lived assets and
certain intangibles to be held and used by the Company be reviewed for
impairment. The Company periodically assesses whether there has been a permanent
impairment of its long-lived assets, in accordance with SFAS No. 121. No
write-down of assets due to impairment was required in the year ended December
31,1997. Approximately $500,000 of goodwill recorded by one of the Acquired
Companies, prior to their acquisition by the Company, was written off in the
year ended December 31, 1996.
 
     New Accounting Pronouncements.  SFAS No. 128, Earnings per Share, is
effective for fiscal years ending after December 15, 1997. This Statement
establishes standards for computing and presenting earnings per share (EPS). The
provisions of this pronouncement have been reflected in accompanying financial
statements. Annual earnings per share has not previously been reported; however,
1997 quarterly information has been restated to comply with SFAS No. 128.
Historical earnings per share calculations for the years ended December 31, 1996
and 1995 have not been presented because it is not considered meaningful as a
result of the exclusion of the Founding Companies as discussed in Note 2.
 
     SFAS No. 130,  Reporting Comprehensive Income, is effective for fiscal
years beginning after December 15, 1997. This Statement establishes standards
for reporting and display of comprehensive income and its components in a full
set of general-purposes financial statements. This Statement requires that all
items that are required to be recognized under accounting standards as
components of comprehensive income be reported in a financial statement that is
displayed with the same prominence as other financial statements.

<PAGE>   56
                          MEDICAL MANAGER CORPORATION
 
         NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
The Company has addressed the requirements of SFAS No. 130 and no material
impact on the financial statements is expected.
 
     SFAS No. 131, Disclosures about Segments of an Enterprise and Related
Information, effective for fiscal years beginning after December 15, 1997,
establishes standards for reporting information about operating segments in
annual financial statements and interim financial reports issued to
shareholders. Generally, certain financial information is required to be
reported on the basis that is used internally for evaluating performance of and
allocation of resources to operating segments. The Company has not yet
determined to what extent the standard will impact its current practice of
reporting operating segment information.
 
     SOP 97-2, Software Revenue Recognition, is effective for fiscal years
beginning after December 15, 1997. This Statement provides guidance on applying
generally accepted accounting principles in recognizing revenue on software
transactions and establishes certain criteria for revenue recognition. The
Company is currently assessing the impact that the revenue recognition criteria
stated in this pronouncement will have on the financial statements.
 
     Reclassifications.  Certain prior year amounts have been reclassified to
conform with 1997 presentations. These reclassifications had no impact on net
income or stockholders' equity.
 
     Concentration of Credit Risk.  The Company's credit concentrations are
limited due to the wide variety of customers in the health care industry and the
geographic areas into which the Company's systems and services are sold.
 
     Non-cash Transactions.  Non-cash transactions during the year included the
purchase of approximately $23.7 million of assets of the other Founding
Companies and the Purchased Companies through the assumption of liabilities and
the issuance of Common Stock.

    stockholder of MMR&D for dividends equal to the estimated balance in the S
    Corporation's Accumulated Adjustment Account as of February 4, 1997 and is
    payable on demand.
 
(2) Balance was paid in full in January 1998 and has been classified as current
    maturities of long-term debt. The line of credit was closed in January 1998.
 
(3) The Notes payable for the remainder of the purchase price for acquisitions
    are due as follows: $231,000 due March 23, 1998; $2,000,000 due June 30,

(4) On August 10, 1994, one of the Acquired Companies entered into a note
    payable in the amount of $250,000. The note was issued in connection with
    the Acquired Company's purchase of certain assets of Solutions Plus, Inc.
    The note is payable in 48 monthly installments, beginning September, 1994.
    Payment of this note is in dispute. The Company has not made payments
    according to its terms; accordingly, the Company may be considered to be in
    default. As a result of the potential default, the entire principal amount,
    plus accrued interest of $99,900, has been recorded as a current liability.
 
(5) These lines of credit were closed during the year ended December 31, 1997.

6.   SUMMARY FINANCIAL DATA OF THE ACQUISITIONS
 
     The acquisitions of the Acquired Companies discussed in Note 1 have been
accounted for as pooling of interests, and accordingly, the consolidated
financial statements for the periods presented have been restated to include the
Acquired Companies. The Acquired Companies generated revenues of $12,818,000 for
the period of January 1, 1997 through their respective acquisition dates and
revenues of $22,387,000 and $16,838,000 for the years ended December 31, 1996
and 1995, respectively. Net income of the Acquired Companies was $199,000 for
the period of January 1, 1997 through their respective acquisition dates and
$111,000 for the year ended December 31, 1996. The Acquired Companies had a net
loss of $73,000 for the year ended December 31, 1995. Changes in the Acquired
Companies' stockholders' equity for the period of January 1, 1997 though their
respective acquisition dates were $790,000. Changes in the Acquired Companies'
stockholders' equity for the year ended December 31, 1996 were $890,000. Changes
in the Acquired Companies' stockholders' equity for the year ended December 31,
1995 were $248,000.
 
     The acquisitions of the Purchased Companies discussed in Note 1 were
accounted for using the purchase method of accounting, and accordingly the
consolidated financial statements reflect the results of operations for the
Purchased Companies only since their respective dates of acquisition. Pro forma
revenues, net income and earnings per share of the Company are presented below
(in thousands, except per share data) as though the acquisitions of Companion
Technologies of Florida, Inc., Companion Technologies of Texas, AMSC, Inc. and
AMSC Midwest, Inc. had occurred as of January 1, 1996. The remainder of the
Purchased Companies' revenues, net income, and earnings per share are not
considered significant.

7.   STOCKHOLDERS' EQUITY
 
     At December 31, 1997, the Company had two stock option plans as described
below:
 
  1996 LONG-TERM INCENTIVE PLAN
 
     In September 1996, the Company adopted the 1996 Long-Term Incentive Plan
(the "Incentive Plan") under which the Compensation Committee has discretion to
grant one or more of the following awards to executive officers, key employees,
consultants and other service providers: (i) incentive stock options, (ii)
nonqualified stock options, (iii) stock appreciation rights, (iv) restricted or
deferred stock (v) dividend equivalents, (vi) bonus shares and awards in lieu of
the Company's obligations to pay cash compensation, and (vii) other awards the
value of which is based in whole or in part upon the value of the Common Stock.
Upon a change of control of the Company (as defined in the Incentive Plan),
certain conditions and restrictions relating to an award with respect to the
ability to exercise or settle such award will be accelerated.
 
     The maximum number of shares of Common Stock that may be subject to
outstanding awards under the Incentive Plan may not exceed the greater of
2,000,000 shares or 10% of the aggregate number of shares of Common Stock
outstanding. The number of shares deliverable upon exercise of incentive stock
options is limited to 500,000, and the number of shares deliverable as
non-performance based restricted stock and deferred stock, is limited to
500,000.

     With the exception of 10,000 options, all of the 1,657,162 options which
were outstanding as of December 31, 1997, have a vesting schedule providing for
25% vesting at 6 months, 18 months, 30 months, and 42 months after the grant
date. There are a total of 10,000 options which vest fully on April 30, 1998.
All options expire 10 years after the date of grant. As of December 31, 1997,
396,463 options granted under the Incentive Plan were exercisable with a
weighted average exercise price of $10.99. No compensation expense related to
the options has been recorded as the options were granted at an exercise price
equal to or greater than the fair market value of the Common Stock on the date
of grant.
 
     A total of 50,000 shares of restricted stock awards were issued under the
Incentive Plan. Compensation expense equal to the fair value of the Common Stock
on the date of grant ($8.375) is being recognized over a five year vesting
period of these stock awards. A total of $49,000 was recognized during the year
ended December 31, 1997.
 
  AMENDED AND RESTATED 1996 NON-EMPLOYEE DIRECTORS' STOCK PLAN
 
     In September 1996, the Company adopted the Amended and Restated 1996
Non-Employee Directors' Stock Plan (the "Directors' Plan") which provides for
the automatic grant to each non-employee director an initial option to purchase
10,000 shares upon such person's initial election as a director. In addition,
the Directors' Plan provides for an automatic annual grant to each non-employee
director of an option to purchase 5,000 shares at each annual meeting of
stockholders; provided, however, that a director will not be granted an annual
option if he or she was granted an initial option during the preceding three
months, later amended to sixty days. This plan also provides that each
non-employee director may elect to receive 2,000 stock options in each calendar
year in lieu of an annual cash fee and other cash payments for attending board
meetings. A total of 250,000 shares are reserved for issuance under the
Directors' Plan. The exercise price of options granted under the Directors' Plan
may be no less than the fair market value of the Common Stock on the date of
grant, and accordingly, no compensation expense has been recorded in connection
with the stock options granted.

outstanding under this plan range from $8.875 to $17.25. As of December 31,
1997, no options granted under the Directors' Plan were exercisable.
 
  FINANCIAL ACCOUNTING STANDARD NO. 123, "ACCOUNTING FOR STOCK BASED
COMPENSATION"
 
     In October 1995, the Financial Accounting Standards Board issued Financial
Accounting Standard No. 123, Accounting for Stock Based Compensation ("FAS 123")
which was effective for fiscal years beginning after December 15, 1995. As
permitted by FAS 123, the Company has elected to account for its stock based
plans under APB No. 25, Accounting for Stock Issued to Employees.
 
     If the Company had elected to recognize compensation expense for stock
options based on the fair value at grant date, consistent with the method
prescribed in FAS 123, net income and earnings per share would have been reduced

     There were no options outstanding as of December 31, 1996, thus pro forma
information is not provided for the year ended December 31, 1996.
 
     The pro forma amounts were determined using the Black-Scholes Valuation
Model with the following key assumptions: (i) a volatility factor initially
based on the Company's average trading price since the IPO, as well as the
average trading stock price of comparable companies over the previous five
years; (ii) no dividend yield; (iii) a discount rate equal to the rate available
on U.S. Treasury Strip (zero-coupon) bond on the grant date, and (iv) an average
expected option life of four years for directors' options and five years for
employees' options.

Company makes a matching contribution of 15% of the first 6% of the compensation
deferred by each participant. Salary reduction contributions are immediately
vested in full; matching contributions vest 20% per year over a five year
period. During the year ended December 31, 1997, the Company made contributions

     Upon the acquisition of MMR&D, Adaptive Health, LSM, SSI, UNICO, Computer
Clinic, C4M, Medysis, Unisource, and CompRx (collectively, the "S
Corporations"), the S Corporation status of these entities terminated.
Accordingly, current and deferred income taxes reflecting the tax effects of
temporary differences between the Company's financial statement tax bases of
certain assets and liabilities became assets and liabilities of the Company.
Accordingly, the above provision for 1997 income taxes includes a $650,000
nonrecurring benefit resulting from the termination of the S Corporation
election and the corresponding required adoption of FAS 109.
 
     The significant components of deferred tax assets and liabilities as of
December 31, 1997 are as follows (in thousands):

12. UNAUDITED PRO FORMA INCOME TAX INFORMATION
 
     Prior to their acquisition, MMR&D, Adaptive Health, LSM, SSI, UNICO,
Computer Clinic, C4M, Medysis, Unisource, and CompRx (collectively, the "S
Corporations") were S corporations and, accordingly, the combined historical
financial statements of MMC, MMR&D and the Acquired Companies did not reflect a
provision for income taxes for the S Corporations, as income taxes were the
responsibility of the S Corporations' individual stockholders. Effective with
their acquisition, the S Corporations terminated their S corporation status. The
following unaudited pro forma income tax information (in thousands), based on
historical information, is presented in accordance with Statement of Financial
Accounting Standards No. 109 as if the S Corporations had each been a C
corporation subject to federal and state income taxes throughout the periods
presented.

13. SUBSEQUENT EVENTS
 
     On January 14, 1998, the Company entered into a $10.0 million line of
credit agreement with Barnett Bank of Tampa. The line of credit matures on May
31, 1999. The line of credit bears interest at Prime or LIBOR, at the election
of the Company, plus an applicable margin, as defined in the agreement. This
debt instrument is due on demand. The agreement contains customary events of
default and a number of customary covenants including certain financial ratios
and restrictions on dividends.
 
     Also subsequent to year-end, the Company executed and closed agreements to
acquire the following resellers of The Medical Manager software: (i) Medical
Practice Support Services, Inc., based in Pittsburgh, Pennsylvania; (ii) Health
Care Management Solutions, Inc. d/b/a Healthcare Informatics, Inc., based in
Springfield, Illinois; and (iii) Strategic Systems, Inc., based in Denver,
Colorado. The acquisitions were accounted for using the pooling of interests
method of accounting. The aggregate consideration paid was 130,509 shares. These
acquisitions, in aggregate, had revenues of $5.8 million and net income of
$400,000 for the year ended December 31, 1997. The acquisitions closed between
February 20 and February 28, 1998.
