Closing Date, as reported (absent manifest error in the printing thereof) by the
Wall Street Journal (Eastern Edition) (the "Average Closing Sale Price"). No
fractional shares of Medical Manager Common Stock will be issued.

         1.5 ASSUMED LIABILITIES. Medical Manager agrees to and will at the

Balance Sheet until the Closing Date in the ordinary course of business
consistent with past practice (the "Assumed Liabilities").

         1.6 EXCLUDED LIABILITIES. Except for the Assumed Liabilities, the
parties expressly agree that Medical Manager shall not assume or otherwise
become liable for any other obligation or liability of the Company, including,

         to be assumed pursuant to the provisions of Section 1.6;

                  (b) any liability or obligation of the Company arising under
         this Agreement;

                                      - 3 -

<PAGE>   5




                  (d) any liability or obligation of the Company to any of the
         Shareholders (including but not limited to that certain payable due
         Dalvin O. Schneider in the amount of $200,000 and that certain payable
         due the Shareholder in the amount of $99,000) or to any party claiming
         to have a right to acquire any shares of capital stock or other
         securities convertible into or exchangeable for any shares of capital
         stock of the Company;

                  (e) any liability or obligation of the Company or Shareholders
         for Taxes, whether arising out of this transaction or otherwise;

                  (f) any liability or obligation (i) with respect to the Leased
         Premises or any other Contract, in the event Medical Manager does not
         receive consents to the assignment of the Company's rights with respect
         to such Contract or Leased Premises, or (ii) with respect to the Leased
         Premises located at 248 W. River Drive, to the extent that the rent
         payable on such lease exceeds fair market value based upon a survey of
         comparable premises; and

                  (g) accrued payroll and related obligations of the Company,
         whether or not appearing on the Current Balance Sheet.

         1.7 NO EXPANSION OF THIRD-PARTY RIGHTS. The assumption by Medical
Manager of the Assumed Liabilities, the transfer thereof by the Company, and the
limitations of such transfer shall in no way expand the rights or remedies of
any third party against Medical Manager or the Company as compared to the rights
and remedies which such third party would have had against the Company had
Medical Manager not assumed such liabilities. Without limiting the generality of
the preceding sentence, the assumption by Medical Manager of the Assumed
Liabilities shall not create any Third-Party beneficiary rights.

         1.8 TAX RETURNS. Following the Closing Date, the Company and Medical
Manager agree that they will cooperate in providing information for the
preparation and filing of all federal, state and local income tax returns on
behalf of the Company or Medical Manager.

the closing of the sale of the Purchased Assets shall take place at the offices
of Medical Manager Corporation, 3001 N Rocky Point Drive East, Tampa, Florida

         surplus or prepaid premiums under any Welfare Plan which is an Employee

         obligates the Company to pay separation, severance, termination or
         similar benefits solely as a result of any transaction contemplated by
         this Agreement or solely as a result of a "change of control" (as such

available, or has been obtained from a third party, without breach of this
provision, shall not be deemed confidential information. No press release or
other public announcement related to this Agreement or the transactions
contemplated hereby shall be issued by any party hereto without the prior
approval of the other parties, except that Medical Manager may make such public
disclosure which it believes in good faith to be required by law or by the terms
of any listing agreement with or requirements of Nasdaq (in which case Medical
Manager will consult with the Company prior to making such disclosure).

         5.8 NO OTHER DISCUSSIONS. The Company and the Shareholders and their
respective Affiliates, employees, agents and representatives will not (a)
initiate or encourage the initiation by others of discussions or negotiations
with third parties, or respond to solicitations by third persons, relating to
any merger, sale or other disposition of any substantial part of the assets,
capital stock (or derivatives thereof), business or properties of the Company
(whether by merger, consolidation, sale of stock or otherwise), or (b) enter
into any agreement or commitment (whether or not binding) with respect to any of
the foregoing transactions. The Company and the Shareholders will immediately
notify Medical Manager if any third party attempts to initiate any solicitation,
discussion or negotiation with respect to any of the foregoing transactions and
shall provide Medical Manager with the name of such third party and the
substance of any communications and terms of any offers.

         5.9 RESTRICTIVE COVENANTS. The Company agrees with Medical Manager that
it will not:

                  (a) for a period of one year from the Closing Date, directly
         or indirectly, alone or as a partner, joint venturer, officer,
         director, member, employee, consultant, agent, independent contractor
         or shareholder of, or lender to, any company or business, engage in any
         business in direct competition with the business of Medical Manager, as
         such business now exists or as it may exist at the time of termination,
         anywhere in the United States; provided, however, that, the beneficial
         ownership of

         less than five percent (5%) of the shares of stock of any other
         corporation having a class of equity securities actively traded on a
         national securities exchange or over-the-counter market shall not be
         deemed, in and of itself, to violate the prohibitions of this Section;

                  (b) for a period of one year from the Closing Date, directly
         or indirectly (i) induce any Person which is a customer of the Company,

         or (iii) request or advise any Person which is a customer or supplier
         of the Company, Medical Manager or any Affiliate of the Company or
         Medical Manager, to withdraw, curtail or cancel any such customer's or
         supplier's business with the Company, Medical Manager or any Affiliate
         of the Company or Medical Manager, or its or their successors;

                  (c) for a period of one year from the Closing Date, directly
         or indirectly employ, or knowingly permit any company or business

         Company or Medical Manager at or within the prior six months, or in any
         manner seek to induce any such person to leave his or her employment;

                  (d) at any time following the Closing Date, directly or

The Company agrees and acknowledges that the restrictions contained in this
Section 5.9 are reasonable in scope and duration and are necessary to protect
Medical Manager after the Closing Date. If any provision of this Section 5.9 as
applied to any party or to any circumstance is adjudged by a court to be invalid
or unenforceable, the same will in no way affect any other circumstance or the
validity or enforceability of this Agreement. If any such provision, or any part
thereof, is held to be unenforceable because of the duration of such provision
or the area covered thereby, the parties agree that the court making such
determination shall have the power to reduce the duration and/or area of such
provision, and/or to delete specific words or phrases, and in its reduced form,
such provision shall then be enforceable and shall be enforced. The parties
agree and acknowledge that the breach of this Section 5.9 will cause irreparable
damage to Medical Manager and upon breach of any provision of this Section 5.9,
Medical Manager shall be entitled to injunctive relief, specific performance or
other equitable relief; provided, however, that, this shall in no way limit any
other remedies which Medical Manager may have (including, without limitation,
the right to seek monetary damages).

         5.10 DUE DILIGENCE REVIEW. Medical Manager shall be entitled to conduct
prior to Closing a due diligence review of the assets, properties, books and
records of the Company.

         5.11 TRADING IN MEDICAL MANAGER COMMON STOCK. Except as otherwise
expressly consented to, in writing, by Medical Manager, from the date of this
Agreement until the Closing Date, neither the Company, the Shareholders nor any
of their Affiliates will directly or indirectly purchase or sell (including
short sales) any shares of Medical Manager Common Stock in any transactions
effected on Nasdaq or otherwise.

         5.12 DELIVERY OF PROPERTY RECEIVED BY THE COMPANY AFTER CLOSING. From
and after the Closing, Medical Manager shall have the right and authority to
collect, for the account of 


                                     - 24 -

Medical Manager, all receivables and other items which shall be transferred or
are intended to be transferred to Medical Manager as part of the Purchased
Assets as provided in this Agreement, and to endorse with the name of the
Company any checks or drafts received on account of any such receivables or
other items of the Purchased Assets. The Company and the Shareholders agree that
they will transfer or deliver to Medical Manager, promptly after the receipt
thereof, any cash or other property which the Company and the Shareholders
receive after the Closing Date in respect of any claims, contracts, licenses,
leases, commitments, sales orders, purchase orders, receivables of any character
or any other items transferred or intended to be transferred to Medical Manager
as part of the Purchased Assets under this Agreement.

         5.13 MEDICAL MANAGER APPOINTED ATTORNEY FOR THE COMPANY. Effective at
the Closing Date, the Company hereby constitutes and appoints Medical Manager,
and Medical Manager's successors and assigns, its true and lawful attorney, in
the name of either Medical Manager or the Company (as Medical Manager shall
determine in its sole discretion) but for the benefit and at the expense of
Medical Manager (except as otherwise herein provided), (a) to institute and
prosecute all proceedings which Medical Manager may deem proper in order to
collect, assert or enforce any claim, right or title of any kind in or to the
Purchased Assets as provided for in this Agreement; (b) to defend or compromise
any and all actions, suits or proceedings in respect of any of the Purchased
Assets, and to do all such acts and things in relation thereto as Medical
Manager shall deem advisable; and (c) to take all action which Medical Manager
may reasonably deem proper in order to provide for Medical Manager the benefits
under any of the Purchased Assets where any required consent of another party to
the sale or assignment thereof to Medical Manager pursuant to this Agreement
shall not have been obtained. The Company acknowledges that the foregoing powers
are coupled with an interest and shall be irrevocable. Medical Manager shall be
entitled to retain for its own account any amounts collected pursuant to the
foregoing powers, including any amounts payable as interest in respect thereof.

         5.14 EXECUTION OF FURTHER DOCUMENTS. From and after the Closing, upon
the reasonable request of Medical Manager, the Company and the Shareholder shall
execute, acknowledge and deliver all such further deeds, bills of sale,
assignments, transfers, conveyances, powers of attorney and assurances as may be
required or appropriate to convey and transfer to and vest in Medical
Manager and protect its right, title and interest in all of the Purchased Assets
and to carry out the transactions contemplated by this Agreement.

         5.15 POST-CLOSING ACTIONS OF THE COMPANY. Following the Closing, the

connection with the orderly liquidation of the Company and distribution of the
Medical Manager Shares to the Shareholders.

Agreement, consents as a director and/or shareholder (as applicable) of the
Company to the transactions contemplated herein, and waives notice of any

                          THE SHAREHOLDERS AND COMPANY

transactions contemplated hereby shall be subject to the fulfillment at or prior
to the Closing Date of the following conditions, any or all of which may be

         7.1 ACCURACY OF REPRESENTATIONS AND WARRANTIES AND COMPLIANCE WITH
OBLIGATIONS. The representations and warranties of Medical Manager contained in
this Agreement shall be true and correct at and as of the Closing Date with the
same force and effect as though made at and as of that time except (a) for
changes specifically permitted by or disclosed pursuant to this Agreement, and
(b) that those representations and warranties which address matters only as of a

Medical Manager shall have delivered to the Company a certificate, dated as of
the Closing Date, and signed by an executive officer, certifying that such

                                  ARTICLE VIII

                                 INDEMNIFICATION

         8.1 AGREEMENT BY THE COMPANY AND THE SHAREHOLDER FOR INDEMNIFICATION.
The Company and the Shareholder jointly and severally agree to indemnify and
hold Medical Manager and its stockholders, directors, officers, employees,
attorneys and Affiliates harmless from and against, and, at Medical Manager's
election, in its sole discretion, Medical Manager shall be entitled to recover
by set off against the Held Back Shares in accordance with Section 8.3, the
aggregate of all expenses, losses, costs, deficiencies, liabilities and damages
(including, without limitation, related counsel and paralegal fees and expenses)
incurred or suffered by Medical Manager arising out of or resulting from (i) any
breach of a representation or warranty made by the Company or the 

                                     - 29 -

<PAGE>   31



Shareholder in or pursuant to this Agreement, (ii) any breach of the covenants
or agreements made by the Company or the Shareholder in or pursuant to this
Agreement or (iii) any inaccuracy in any certificate, instrument or other
document delivered by the Company or the Shareholder as required by this
Agreement and (iv) any transfer taxes that may be due and owing to any
Governmental Authority (collectively, "Indemnifiable Damages"). Without limiting
the generality of the foregoing, with respect to the measurement of
Indemnifiable Damages, Medical Manager shall have the right to be put in the
same pre-tax consolidated financial position as it would have been in had each
of the representations and warranties of the Company and the Shareholder
hereunder been true and correct and had the agreements of the Company and the
Shareholder hereunder been performed in full. Notwithstanding anything to the
contrary contained herein, Indemnifiable Damages shall not exceed the Purchase
Price.

         8.2 SURVIVAL OF REPRESENTATIONS AND WARRANTIES. Each of the
representations and warranties made by the Company and the Shareholder in this
Agreement or pursuant hereto shall survive for a period of one year after the
Closing Date. No claim for the recovery of Indemnifiable Damages may be asserted
by any party after such representations and warranties shall thus expire;
provided, however, that claims for Indemnifiable Damages first asserted within
the applicable period shall not thereafter be barred. Notwithstanding any
knowledge of facts determined or determinable by any party by investigation,
each party shall have the right to fully rely on the representations,
warranties, covenants and agreements of the other parties contained in this
Agreement or in any other documents or papers delivered in connection herewith.
Each representation, warranty, covenant and agreement of the parties contained
in this Agreement is independent of each other representation, warranty,
covenant and agreement. Each of the representations and warranties of Medical
Manager shall expire on the Closing Date.

         8.3 SECURITY FOR INDEMNIFICATION OBLIGATION. As security for the
indemnification obligations contained in this Article VIII, at the Closing,
Medical Manager shall set aside and hold, and the Company and the Shareholder
hereby grant a security interest in the shares represented by, the certificates
representing the Held Back Shares issued pursuant to this Agreement. Medical
Manager may set off against the Held Back Shares any loss, damage, cost or
expense for which the Company or the Shareholder may be responsible pursuant to
this Agreement (including without limitation, any Indemnifiable Damages) whether
or not indemnified pursuant to this Article VIII, subject, however, to the
following terms and conditions:

                  (a) Medical Manager shall give written notice to the Company
         of any claim for Indemnifiable Damages or any other damages hereunder,
         which notice shall set forth (i) the amount of Indemnifiable Damages or
         other loss, damage, cost or expense which Medical Manager claims to
         have sustained by reason thereof, and (ii) the basis of such claim;

                  (b) Such set off shall be effected on the later to occur on
         the expiration of 10 days from the date of such notice (the "Notice of
         Contest Period") or, if such claim is contested, the date the dispute
         is resolved, and such set off shall be charged proportionally against
         the shares set aside;


                                     - 30 -

<PAGE>   32




                  (c) After any restrictions on sale imposed under the
         Securities Act or otherwise are terminated, the Company may, not more
         than once during any calendar year, instruct Medical Manager to sell
         some or all of the Held Back Shares and the net proceeds thereof shall
         be substituted for such Held Back Shares in any set off to be made by
         Medical Manager pursuant to any claim hereunder subject to continued
         compliance with any applicable SEC and other regulations; and

                  (d) For purposes of any set off against the Held Back Shares
         pursuant to this Article VIII, the shares of Medical Manager Common
         Stock not sold as provided in clause (c) of this Section shall be
         valued at the Average Closing Sale Price.

         8.4 VOTING OF AND DIVIDENDS ON THE HELD BACK SHARES. Except with
respect to shares transferred pursuant to the foregoing right of set off (and in
the case of such shares, until the same are transferred), all Held Back Shares
shall be deemed to be owned by the Company and the Company shall be entitled to
vote the Held Back Shares; provided, however, that, there shall also be
deposited with Medical Manager subject to the terms of this Article VIII, all
shares of Medical Manager Common Stock issued to the Company as a result of any
stock dividend or stock split and all cash issuable to the Company as a result
of any cash dividend, with respect to the Held Back Shares. All stock and cash
issued or paid upon Held Back Shares shall be distributed to the person or
entity entitled to receive such Held Back Shares together with such Held Back
Shares.

         8.5 DELIVERY OF HELD BACK SHARES. Medical Manager agrees to deliver to
the Company no later than one year after the Closing Date any Held Back Shares
then held by it (or proceeds from
the Held Back Shares) unless there then remains unresolved any claim for
Indemnifiable Damages or other damages hereunder as to which notice has been
given, in which event any Held Back Shares remaining on deposit (or proceeds
from the sale of Held Back Shares) after such claim shall have been satisfied
shall be returned to the Company promptly after the time of satisfaction.

         8.6 ADJUSTMENT TO PURCHASE PRICE. All payments for Indemnifiable
Damages made pursuant to this Article VIII shall be treated as adjustments to
the Purchase Price.

         8.7 NO BAR. If the Held Back Shares are insufficient to set off any
claim for Indemnifiable Damages made hereunder (or have been delivered to the
Company prior to the making or resolution of such claim), then Medical Manager
may take any action or exercise any remedy available to it by appropriate legal
proceedings to collect the Indemnifiable Damages.

         8.8 REMEDIES CUMULATIVE. The remedies provided herein shall be
cumulative and shall not preclude Medical Manager from asserting any other
right, or seeking any other remedies against the Shareholders or the Company.

         from the Company) hereunder are being acquired and will be acquired for

         1.4 PURCHASE PRICE As consideration for the Purchased Assets, Medical
Manager agrees, on the terms and subject to the conditions and limitations set
forth herein, to pay to the Company at the closing (as defined in SECTION 1.10)
an aggregate amount equal to Three Million Five Hundred Thousand Dollars and
no/100 ($3,500,000.00) (the "Purchase Price"). Medical Manager will pay One
Million Dollars and no/100 ($1,000,000.00) in cash, by wire transfer or other
immediately available funds, to the Company, and will issue to the Company a
stock certificate representing a number of shares (rounded to the nearest whole
share) of common stock, par value $ .01 per share, of Medical Manager
Corporation (the "Medical Manager Common Stock") equal to the number of shares
determined by dividing (a) Two Million Five Hundred Thousand Dollars and no/100
($2,500,000.00) MINUS the amount, if any, by which the Company's Net Assets (as
defined below), as of the Closing Date, is less than One Million Two Hundred
Thousand Dollars and no/100 ($1,200,000.00) (the "Purchase Price Adjustment");
by (b) the average closing sale price of a share of Medical Manager Common Stock
as quoted on the NASDAQ Stock Market ("NASDAQ") for the five consecutive trading
days which precede the third trading day which is immediately prior to the
Closing Date, as reported (absent manifest error in the printing thereof) by THE
WALL STREET JOURNAL (Eastern Edition) (the "Average Closing Sale Price"). No
fractional shares of Medical Manager Common Stock will be issued. For purposes
of determining the Purchase Price Adjustment, "Net Assets" shall mean the amount
of the Purchased Assets of the Company, the value of which shall be determined
in accordance with GAAP, minus the Assumed Liabilities (defined in Section 1.6
below) of the Company.

         1.5 PURCHASE PRICE ADJUSTMENT Within 90 days after the Closing Date,
Medical Manager shall prepare and deliver to the Company (in accordance with
SECTION 12.1) a determination (the "Determination") of the actual amount of the
Purchase Price Adjustment as of the Closing Date. If, within 30 days after the
date on which a Determination is delivered to the Company, the Company shall not
have given written notice to Medical Manager setting forth in detail any
objection of the Company to such Determination, then such Determination shall be
final and binding on the parties hereto and shall be payable by the Company and
the Shareholders to Medical Manager. In the event the Company gives written
notice of any objection to such Determination within the 30-day period, Medical
Manager and the Company shall use all reasonable efforts to resolve the dispute
within the 30-day period following the delivery of the written notice. If the
parties are unable to reach an agreement within such 30-day period, the matter
shall be submitted to a firm of independent certified public accountants (which
company shall constitute one of the "Big Six" accounting firms excluding Coopers
& Lybrand, LLP), for determination of the Purchase Price Adjustment which shall
be final and binding upon Medical Manager and the Company. All costs (including
fees and expenses charged by the accounting firm) incurred in connection with
the resolution of any such dispute shall be paid as determined by such firm of
independent accountants. Medical Manager shall be entitled to set off against
the Held Back Shares (as defined in SECTION 1.11(D)) the amount of the Purchase
Price Adjustment (assuming a value per share for purposes of such calculation
equal to the Average Closing Sale Price). The amount of the Purchase Price
Adjustment shall be deemed to be Indemnifiable Damages under ARTICLE VIII
hereof, but shall not be subject to the limitations of Section 8.2(a) hereof).

         1.6 ASSUMED LIABILITIES Medical Manager agrees to and will at the
Closing assume and agree to pay, discharge and perform when lawfully required

Excluded Liabilities, and (iii) all obligations, liabilities and duties of the
Company arising under any franchise contract, sales order, sales contract,
supply contract, service agreement, lease, purchase order, and purchase

         or obligation listed on the Current Balance Sheet of the Company for
         accrued vacation over 40 hours in respect of any employee of the
         Company hired by Medical Manager;

                  (g) any liability or obligation of the Company to any of the

         1.8 NO EXPANSION OF THIRD-PARTY RIGHTS The assumption by Medical
Manager of the Assumed Liabilities, the transfer thereof by the Company, and the
limitations of such transfer shall in no way expand the rights or remedies of
any third party against Medical Manager or the Company as compared to the rights
and remedies which such third party would have had against the Company had
Medical Manager not assumed such liabilities. Without limiting the generality of
the preceding sentence, the assumption by Medical Manager of the Assumed
Liabilities shall not create any Third- Party beneficiary rights.

Shareholders agree that the Purchase Price will be allocated pursuant to the
allocations set forth on SCHEDULE 1.9. In the event SCHEDULE 1.9 is not attached

business relationship with the Company for any reason. Neither the Company nor
any of the Shareholders have any direct or indirect equity interest in any
customer, supplier or competitor of the Company, or in any person from whom or

under the Medical Manager medical and dental plans for purposes of any exclusion
of coverage for pre-existing conditions of the former employees of the Company
which are hired by Medical Manager.

         of any claim of fraud or any statutory violation in the nature of
         fraud, or in respect of any breach of Sections 3.13(b) or 5.13(b)
         hereof, or in respect of the payment of the Purchase Price Adjustment
         under Section 1.5 or any claim for uncollected Receivables under
         Section 3.20 hereof. Any claims falling within the categories
         enumerated in the immediately preceding sentence shall not count
         against the $50,000 Indemnification Threshold. In no event shall the
         aggregate amount of Indemnifiable Damages payable by the Company and
         the Shareholders exceed $1,323,672.00.

                  (b) Each of the representations and warranties made by the
         Company and the Shareholders and Medical Manager in this Agreement or
         pursuant hereto shall survive for a period of two years after the
         Closing Date. No claim for the recovery of Indemnifiable Damages may be
         asserted by any party after such representations and warranties shall
         thus expire; PROVIDED, HOWEVER, that claims for Indemnifiable Damages
         first asserted within the applicable period shall not thereafter be
         barred. Notwithstanding any knowledge of facts determined or
         determinable by any party by investigation, each party shall have the
         right to fully rely on the representations, warranties, covenants and
         agreements of the other parties contained in this Agreement or in any
         other documents or papers delivered in connection herewith. Each
         representation, warranty, covenant and agreement of the parties
         contained in this Agreement is independent of each other
         representation, warranty, covenant and agreement.

         8.3 SECURITY FOR INDEMNIFICATION OBLIGATION As security for the
indemnification obligations contained in this ARTICLE VIII, at the Closing,
Medical Manager shall set aside and hold, and the Company and the Shareholders
hereby grant a security interest in the shares represented by, the certificates
representing the Held Back Shares issued pursuant to this Agreement. Medical
Manager may set off against the Held Back Shares any loss, damage, cost or
expense for which the Company or the Shareholders may be responsible pursuant to
this Agreement (including without limitation, any Indemnifiable Damages) whether
or not indemnified pursuant to this ARTICLE VIII, subject, however, to the
following terms and conditions:

                  (a) Medical Manager shall give written notice to the Company
         of any claim for Indemnifiable Damages or any other damages hereunder,
         which notice shall set forth (i) the amount of Indemnifiable Damages or
         other loss, damage, cost or 


                                      -29-
<PAGE>   31

         expense which Medical Manager claims to have sustained by reason
         thereof, and (ii) the basis of such claim;

                  (b) Such set off shall be effected on the later to occur on
         the expiration of 10 days from the date of such notice (the "Notice of
         Contest Period") or, if such claim is contested, the date the dispute
         is resolved, and such set off shall be charged proportionally against
         the shares set aside;

                  (c) After any restrictions on the sale of the Held Back Shares
         imposed under the Securities Act or otherwise are terminated, the
         Company may, not more than once during any calendar year, instruct
         Medical Manager to sell some or all of the Held Back Shares and the net
         proceeds thereof shall be substituted for such Held Back Shares in any
         set off to be made by Medical Manager pursuant to any claim hereunder
         subject to continued compliance with any applicable SEC and other
         regulations; and

                  (d) For purposes of any set off against the Held Back Shares
         pursuant to this ARTICLE VIII, the shares of Medical Manager Common
         Stock not sold as provided in clause (c) of this Section shall be
         valued at the Average Closing Sale Price.

         8.4 VOTING OF AND DIVIDENDS ON THE HELD BACK SHARES Except with respect
to shares transferred pursuant to the foregoing right of set off (and in the
case of such shares, until the same are transferred), all Held Back Shares shall
be deemed to be owned by the Company and the Company shall be entitled to vote
the Held Back Shares; PROVIDED, HOWEVER, that, there shall also be deposited
with Medical Manager subject to the terms of this ARTICLE VIII, all shares of
Medical Manager Common Stock issued to the Company as a result of any stock
dividend or stock split and all cash issuable to the Company as a result of any
cash dividend, with respect to the Held Back Shares. All stock and cash issued
or paid upon Held Back Shares shall be distributed to the person or entity
entitled to receive such Held Back Shares together with such Held Back Shares.

         8.5 [RESERVED]

         8.6 ADJUSTMENT TO PURCHASE PRICE All payments for Indemnifiable Damages
made pursuant to this ARTICLE VIII shall be treated as adjustments to the
Purchase Price.

         8.7 NO BAR If the Held Back Shares are insufficient to set off any
claim for Indemnifiable Damages made hereunder (or have been delivered to the
Company prior to the making or resolution of such claim), then Medical Manager
may take any action or exercise any remedy available to it by appropriate legal
proceedings to collect the Indemnifiable Damages.

         8.8 REMEDIES CUMULATIVE The remedies provided herein shall be
cumulative and shall not preclude Medical Manager from asserting any other
right, or seeking any other remedies against the Shareholders or the Company.

losses, costs, deficiencies, liabilities and damages (including, without
