                              EMPLOYMENT AGREEMENT

                  EMPLOYMENT AGREEMENT (the "Agreement") dated as of April 4,
2000, by and between MEDICAL MANAGER CORPORATION, a Delaware corporation (the
"Company"), and KEVIN CAMERON ("Executive").

                  WHEREAS, the Company desires to employ Executive on a
full-time basis and Executive desires to be so employed by the Company;

                  NOW, THEREFORE, in consideration of the mutual covenants in
this Agreement, the parties agree as follows:

         1.       Effectiveness of Agreement and Employment of Executive.

                  1.1.     Effectiveness of Agreement. This Agreement shall
become effective as of April 4, 2000 (the "Effective Date").

                  1.2.     Employment by the Company. The Company hereby employs
Executive and Executive hereby accepts such employment with the Company.
Executive shall report to the Chairman of the Board of the Company. Executive's
title shall initially be Executive Vice President--Corporate Development.
Executive shall perform such duties and services for the Company, its
subsidiaries and affiliates (as such term is defined in Rule 12b-2 promulgated
under the Securities Exchange Act of 1934, as amended) (such subsidiaries and
affiliates collectively, "Affiliates"), and at such Non-Distant offices (as
hereinafter defined), as may be designated from time to time by the Company.
Executive shall use his best and most diligent efforts to promote the interests
of the Company and the Affiliates, and shall devote all of his business time and
attention to his employment under this Agreement; provided, however, that
Executive shall be permitted to manage his personal, financial and legal affairs
that may from time to time require insubstantial portions of his working time,
but would not singularly or in the aggregate interfere or be inconsistent with
his duties and obligations under this Agreement.

                  1.3. Confidentiality. Executive understands and acknowledges
that in the course of his employment, he will have access to and will learn
information that is proprietary to, or confidential to the Company and its
Affiliates that concerns the operation, methodology and plans of the Company and
its Affiliates, including, without limitation, business strategy and plans,
financial information, protocols, proposals, manuals, clinical procedures and
guidelines, technical data, computer source codes, programs, software, know-how
and specifications, copyrights, trade secrets, market information, Developments
(as hereinafter defined), information regarding acquisition and other strategic
partner candidates, and customer information (collectively, "Proprietary
Information"). Executive agrees that, at all times (including following
termination of his employment with the Company), he will keep confidential and
will not disclose directly or indirectly any such Proprietary Information to any

<PAGE>

third party, except as required to fulfill his duties hereunder, and will not
misuse, misappropriate or except as required to fulfill his duties hereunder,
exploit such Proprietary Information in any way. The restrictions contained
herein shall not apply to any information which Executive can demonstrate (i)
was already available to the public at the time of disclosure, or subsequently
becomes available to the public, otherwise than by breach of this Agreement by
Executive or (ii) was the subject of a subpoena or self regulatory organization,
governmental agency or court order for Executive to disclose. Upon any
termination of Executive's employment, Executive shall immediately return to the
Company all copies of any Proprietary Information in his possession.

                  1.4.     Restrictions on Solicitation. During the period
beginning on the Effective Date and ending on the first anniversary of the date
of cessation of the employment of Executive for any reason whatsoever (the
"Restricted Period"), Executive shall not, directly or indirectly, without the
prior written approval of the Company, solicit or contact any customer, or any
prospective customer (with whom Executive had material contact during his
employment by the Company) of the Company or any of the Affiliates for any
commercial pursuit which is in competition with the Company or any of the
Affiliates, or that is contemplated from time to time by the Business Plan (as
defined below) or take away or interfere or attempt to interfere with any
custom, trade, business or patronage of the Company or any of the Affiliates.
During the Restricted Period, Executive shall not, directly or indirectly,
without the prior written approval of the Company, solicit or induce, or attempt
to induce, any employees, agents or consultants of or to the Company or any of
the Affiliates to leave the employ of the Company or such Affiliate or do
anything from which Executive is restricted by reason of this Agreement nor
shall Executive, directly or indirectly, offer or aid others to offer employment
to or interfere or attempt to interfere with any employees, agents or
consultants of the Company or any of the Affiliates. For purposes of this
Agreement, "Business Plan" shall mean, at any point in time, the then current
business plan of the Company or any of the Affiliates and any business plans of
the Company or any of the Affiliates in effect during the prior 18 months, in
any case, as provided to Executive prior to the termination of his employment.

                  1.5.     Restrictions on Competitive Employment. (a) During
the Restricted Period, Executive shall not, anywhere in the United States,
directly or indirectly, without the prior written approval of the Company, own
an interest in or, as principal, agent, employee, consultant or otherwise,
engage in activities for or render services to, any firm or business (i) engaged
in competition with the Company or any of its Affiliates, (ii) conducting a
business of the type and character engaged in by (or contemplated by the
Business Plan of) the Company or any of its Affiliates at the time of
termination, (iii) developing products or services competitive with those of the
Company or any of its Affiliates or (iv) conducting any business in which the
Company or any of its Affiliates is then engaged if Executive has engaged in
activities for such business of the Company or such Affiliates or obtained
Proprietary Information with respect thereto (all of the businesses in clauses
(i), (ii), (iii) and (iv) collectively, "Competitive Business"). Notwithstanding
the foregoing, (A) Executive may have an interest consisting of publicly traded
securities constituting less than 1 percent of any class of publicly traded
securities in any public company engaged in a Competitive Business so long as he
is not employed by and does not consult with, or become a director of or
otherwise engage in any


                                       2
<PAGE>

activities for, such company; (B) Executive may continue to hold, although with
respect to each of such companies, not increase to more than 2% of the equity of
such company on a fully diluted basis, his portfolio investments in
"Healthmarket" and "Digital Medial Systems," but during the Restricted Period
Executive may not become a director of or, other than to ascertain the status of
Executive's investments or in furtherance of his duties hereunder, consult with,
or otherwise engage in any activities for either of such companies; and (C) in
determining whether business is a Competitive Business, only the activities
engaged in by the Company at the time of termination of Executive's employment
or contained in the Business Plan shall be considered.

                  (b)      For purposes of the covenant not to compete set forth
in paragraph (a) above, Executive acknowledges that the Company and its
Affiliates presently conduct their businesses throughout the United States.
Executive agrees that the Restricted Period and the geographical areas
encompassed by such covenant are necessary and reasonable in order to protect
the Company and its Affiliates in the conduct of their businesses. The parties
intend that the foregoing covenant of Executive shall be construed as a series
of separate covenants, one for each geographic area specified. Except for
geographic coverage, each such separate covenant shall be deemed identical in
terms to the covenant set forth in paragraph (a) above. To the extent that the
foregoing covenant or any provision of this Section 1.5 shall be deemed illegal
or unenforceable by a court or other tribunal of competent jurisdiction with
respect to (i) any geographic area, (ii) any part of the time period covered by
such covenant, (iii) any activity or capacity covered by such covenant or (iv)
any other term or provision of such covenant, such determination shall not
affect such covenant with respect to any other geographic area, time period,
activity or other term or provision covered by or included in such covenant.

                  1.6.     Assignment of Developments. All Developments that are
at any time made, conceived or suggested by Executive, whether acting alone or
in conjunction with others, arising out of or as a result of Executive's
employment with the Company shall be the sole and absolute property of the
Company and the Affiliates, free of any reserved or other rights of any kind on
Executive's part. During Executive's employment and, if such Developments were
made, conceived or suggested by Executive during or as a result of Executive's
employment under this Agreement or any other employment with the Company or the
Affiliates, thereafter, Executive shall promptly make full disclosure of any
such Developments to the Company and, at the Company's cost and expense, do all
acts and things (including, among others, the execution and delivery under oath
of patent and copyright applications and instruments of assignment) deemed by
the Company to be necessary or desirable at any time in order to effect the full
assignment to the Company and the Affiliates of Executive's right and title, if
any, to such Developments. For purposes of this Agreement, the term
"Developments" shall mean all data, discoveries, findings, reports, designs,
inventions, improvements, methods, practices, techniques, developments,
programs, concepts, and ideas, whether or not patentable, relating to the
present activities, planned activities, as reflected in the Business Plan, or
future activities initiated by the Company or the Affiliates during Executive's
employment by the Company, or the products and services of the Company or any of
the Affiliates initiated during the term of Executive's Employment or as
reflected in the Business Plan.

                  1.7.     Remedies. Executive acknowledges and agrees that
damages for a breach or threatened breach of any of the covenants set forth in
Sections 1.3 through 1.6 will be difficult to determine and will not afford a
full and adequate remedy, and therefore agrees that the Company, in addition to
seeking actual damages in connection therewith, may seek specific enforcement of
any such covenant in any court of competent jurisdiction, including, without
limitation, by the issuance of a temporary or permanent injunction.

         2.       Compensation and Benefits.

                  2.1.     Salary. The Company shall pay Executive for services

Any and all increases to Executive's Base Salary shall be determined by the
Board of Directors of the Company, in its sole discretion. Such Base Salary
shall be payable in equal installments, no less frequently than monthly,
pursuant to the Company's customary payroll policies in force at the time of
payment, less any required or authorized payroll deductions.

                  2.2.     Benefits. During his employment under this Agreement,
Executive shall be entitled to participate, on the same basis and at the same
level as other similarly situated executives of the Company, in any group

benefit and tax-qualified retirement plans or programs or vacation leave of the
Company now existing or hereafter established to the extent that he is eligible
under the general provisions thereof.

                  2.3.     Expenses. Pursuant to the Company's customary
policies in force at the time of payment, Executive shall be promptly
reimbursed, against presentation of vouchers or receipts therefor, for all
authorized expenses properly and reasonably incurred by him on behalf of the
Company or its Affiliates in the performance of his duties hereunder.

                  2.4.     Loan. Subject to the consent of Healtheon/ WebMD

days of a written request by Executive during the term of his employment the
Company shall provide a loan to Executive (the "Loan") in the principal amount

<PAGE>

connection with the negotiation of this Agreement and any other prospective
employment relationships that Executive was considering within 90 days prior to
the date hereof.

                  2.7      Relocation. If the Company requests that Executive

Upon the presentation of invoices, the Company shall reimburse, on an after tax
basis, Executive's reasonable out-of-pocket expenses, including, without
limitation, real estate brokerage fees, related to the relocation of him and his

                           shall no longer be the Chairman of the Board of the
                           Company or a senior executive officer of the
                           acquiring entity, in each case with duties and
                           responsibilities greater than or substantially
                           equivalent to those prior to such sale of assets; or

payments and benefits under Sections 4 and 5 resulting from a termination of his
employment with the Company are in lieu of any and all claims that Executive may
have against the Company (other than benefits under the Company's employee
benefit plans that by their terms survive termination of employment and benefits
under the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended and
rights to indemnification under certain indemnification arrangements for
officers of the Company), and represent liquidated damages (and not a penalty).
The Company may request that Executive confirm such acknowledgment in writing
prior to the receipt of such benefits.
