                              EMPLOYMENT AGREEMENT

         THIS EMPLOYMENT AGREEMENT (the "Agreement") by and between InfoCure
Corporation, a Delaware corporation ("Company"), and Michael A. Manto
("Executive"), is hereby entered into as of the 24th day of July, 2000 (the
"Effective Date").

         WHEREAS, Company is engaged in the business of providing practice
management software products and related services that address the needs of
health care providers to manage and communicate administrative, practice
management and clinical applications designed to meet the information
requirements of medical specialties and office-based health care practices in
the United States (the "Business"); and

         WHEREAS, Executive desires to be employed by Company at its offices in
Ridgefield, Connecticut and Company desires to employ and assure itself of the
continued services of Executive on the terms and conditions set forth herein.

         NOW, THEREFORE, in consideration of the mutual promises, terms,
covenants and conditions set forth herein and the performance of each, it is
hereby agreed as follows:

         1.       Employment and Duties.

                  A.       Company shall employ Executive as an Executive Vice
President during the term of his employment as set forth in this Agreement and
Executive hereby accepts such employment. Executive shall report solely to the
Chief Executive Officer or if there is none, to the President ("CEO") of the
Company and shall perform the responsibilities of an Executive Vice President
and such additional executive duties and responsibilities commensurate with his
position as shall be reasonably assigned by the CEO of the Company. The
Executive shall not be required to maintain his principal office other than in
Ridgefield, Connecticut or within forty (40) miles thereof.

                           The parties acknowledge that it is currently the
intention of the Company to spin-off its "PracticeWorks" subsidiary by means of
a pro rata dividend of all of the Company's "interests" in PracticeWorks to the
stockholders of the Company (such transaction being hereinafter referred to as
the "Spin-Off"). If the Company completes the Spin-Off, Executive, in addition
to his position as Executive Vice President, shall be appointed Chief Financial
Officer of the Company.

                  B.       Upon completion of the Spin-Off, the Company shall
cause the Executive to be nominated for and elected to the Board of Directors of
the Company with such appointment remaining in effect throughout the term of
this Agreement and any extensions thereof.

                  C.       The Executive shall devote approximately forty (40)
hours per week to the performance of his duties hereunder. Neither the foregoing
nor any other provision of this Agreement is intended or shall be construed as
preventing Executive from devoting his time and effort to charitable, community
activities and other business non-competitive to the Business, including but not
limited to as a board member or senior advisor, provided that such involvement

with such activities does not materially interfere with the performance of his
duties under this Agreement.

         2.       Compensation and Benefits.

                  A.       Base Salary. During the Term (as defined below),
Company shall pay to Executive a base salary ("Base Salary") of One Hundred
Ninety Thousand Dollars ($190,000) per year, payable in arrears in accordance
with the Company's standard payroll practices for senior executives (but in no
event less frequently than in equal semi-monthly payments). During the Term, the
Base Salary shall be reviewed at least annually and shall be increased (but not
decreased) from time to time, but not less than annually, as determined by the
CEO and/or Board of Directors, after consultation with the Executive. Any
increase in Base Salary shall not limit or reduce any other obligation of the
Company to the Executive under this Agreement.

                  B.       Annual Bonus. The Company shall pay to Executive an
annual cash bonus ("Annual Bonus") as set forth below for each calendar year.
During the year ending December 31, 2000, Executive shall be guaranteed an
Annual Bonus payment of fifty percent (50%) of his Base Salary and shall be
entitled to earn an additional amount up to another fifty percent (50%) of his
Base Salary as an Annual Bonus based upon his achievement of target performance
goals, mutually agreed upon by Executive and the CEO and/or Board of Directors
(the "Target Annual Goals"). Thereafter, for the reminder of this Agreement and
any extensions thereof, Executive shall be entitled to earn up to one hundred
percent (100%) of his then current Base Salary as an Annual Bonus, of which at
least fifty percent (50%) shall be earned if the Target Annual Goals are
achieved and up to an additional 50% shall be earned if the Target Annual Goals
are exceeded. The Target Annual Goals shall be established by "mutual agreement"
by September 30, 2000 for the calendar year 2001 and thereafter within ninety
(90) days after the first day of the applicable calendar year. All bonuses
provided for in this Section 2.B shall be due and payable within thirty (30)
days after the conclusion of the calendar year. For any calendar year in which
Executive has not worked the entire year, for purposes of determining whether
the Annual Bonus has been earned, Executive shall be measured only by his
performance for that period of the year worked.

                  C.       Most Favored Nations: Additional Employee Benefits,
Bonus and Incentive Compensation. During the Term (as defined below), Executive
shall be entitled to participate in all employee benefit programs and policies
provided by the Company, including, without limitation, deferred compensation
plans; equity-based compensation; severance; and medical, dental, accidental
death, life, travel, accident and short and long term disability insurance
plans. Executive's participation shall be at the highest benefit level offered
to any other senior executive of the Company. Executive shall also be entitled
during the Term to the highest bonus compensation and incentive compensation,
including without limitation stock options and other stock and equity-based
compensation, as provided to any other senior executive of the Company.

                  D.       Vacation. Executive shall accrue five (5) weeks of
vacation during each calendar year during the Term of this Agreement (with such
vacation time pro-rated for 2000). Vacation time shall be taken at such time as
not to materially interfere with the Business of Company. Any unused vacation
time may be carried forward from year to year.

                                       2
<PAGE>   3

                  E.       Business Expenses. The Executive shall be entitled to
be reimbursed promptly for reasonable business expenses incurred by him in
connection with his services hereunder in accordance with the Company's policies
and procedures for its senior executives.

                  F.       Auto Allowance. Executive shall receive a $1,500/per
month automobile allowance from the Company, payable monthly.

                  G.       Indemnification. Executive shall be indemnified and
held harmless by the Company to the greatest extent permitted under Delaware law
as the same now exists or may hereafter be amended (but, in the case of any such
amendment, only to the extent that such amendment permits the Company to provide
broader indemnification than was permitted prior to such amendment) and under
the Company's by-laws as such exist on the Effective Date, if Executive is or
was made, or is threatened to be made, a party to any pending, completed or
threatened action, suit, arbitration, alternative dispute resolution mechanism,
investigation, administrative hearing or any other proceeding whether civil,
criminal, administrative or investigative, and whether formal or informal, by
reason of the fact that Executive is or was, or had agreed to become, a
director, officer, employee, agent, or fiduciary of the Company or any other
entity which Executive is or was serving at the request of the Company
("Proceeding"). Such indemnification shall be against all expenses (including
all reasonable attorneys' fees (including any fees for separate counsel so
chosen by the Executive), retainers, court costs, transcripts, fees of experts,
witness fees, travel expenses, duplicating costs, printing and binding costs,
telephone charges, postage, delivery service fees, and all other reasonable
disbursements or expenses customarily required in connection with asserting or
defending claims) ("Expenses") and all claims, damages, liabilities and losses
(including judgments, fines, and liabilities under the Internal Revenue Code or
the Employee Retirement Income Security Act of 1974, as amended, for damages,
excise taxes or penalties; damages, fines or penalties arising out of violation
of any law related to the protection of the public health, welfare or the
environment; and amounts paid or to be paid in settlement) incurred or suffered
by Executive or to which Executive may become subject for any reason.

                           (i)      Advancement of Expenses and Costs. All
Expenses incurred by or on behalf of Executive in defending or otherwise being
involved in a Proceeding shall be paid by Company in advance of the final
disposition of a Proceeding, including any appeal therefrom, within 30 days
after the receipt by the Company of a statement or statements from Executive
requesting such advance or advances from time to time. Such statement or
statements shall evidence the Expenses incurred by Executive in connecting
therewith, together with supporting invoices, receipts and other documentation.

                           (ii)     Effect of Certain Proceedings. The
termination of any Proceeding by judgment, order, settlement or conviction, or
upon a plea of nolo contendere or its equivalent, except, in each case, to the
extent that the terms thereof expressly so provide, shall not, of itself (i)
adversely affect the rights of Executive to indemnification, or (ii) create a
presumption that Executive did not meet any particular standard of conduct or
have any particular belief or that a court has determined that indemnification
or contribution is not permitted by applicable law.

                           (iii)    Other Rights to Indemnification. Executive's
rights of indemnification and advancement of Expenses provided by this Section
2G shall not be deemed

                                       3
<PAGE>   4

exclusive of any other rights to which Executive may now or in the future be
entitled under applicable law, the certificate of incorporation, by-laws,
agreement, vote of stockholders, or resolution of the Board, or other provisions
of this Agreement or any other agreement, or otherwise.

                           (iv)     Representations. The Company represents and
warrants that this Section 2G does not conflict with or violate its certificate
of incorporation or by-laws, and agrees that it will not amend its certificate
of incorporation or by-laws in a manner that would limit the rights of Executive
hereunder. The Company represents that the execution, delivery and performance
of this Agreement has been duly and validly authorized by the Board.

                           (v)      Survival of Indemnity. Notwithstanding
anything in this Agreement to the contrary, this Section 2.G shall survive any
termination of the relationship of Executive with the Company and shall be
binding on, and inure to the benefit of the successors and assigns of the
Company and the successors, assigns, heirs and personal representatives of
Executive.

                           (vi)     The Company agrees to maintain appropriate
Directors' and Officers' Liability Insurance.

                  (H)      Option Grants.

                           (i)      On August 21, 2000, the Company shall grant
to the Executive incentive stock options for the purchase of 750,000 shares of
the Common Stock, $0.001 par value per share, of the Company ("Common Stock") at
a per share exercise price equal to the closing price per share of Common Stock
as reported on the Nasdaq National Market on August 21, 2000. Such options shall
(i) vest during a 36-month period, in 12 equal quarterly installments commencing
on the three-month anniversary of the Effective Date, provided, however, that
(a) the vesting of options to purchase 375,000 shares of Common Stock shall be
accelerated and become fully exerciseable on the first day after the date on
which the average closing price of the Common Stock for 20 consecutive trading
days, as reported on the Nasdaq National Market, is greater than or equal to
$8.88 per share (with the remaining unvested shares, if any, continuing to vest
and become exerciseable on their original, 36-month, vesting schedule) and (b)
the vesting of the balance of such options to purchase shares of Common Stock
shall be accelerated and become fully exerciseable on the first day after the
date on which the average closing price of the Common Stock for 20 consecutive
trading days, as reported on the Nasdaq National Market, is greater than or
equal to $13.32 per share, (ii) be on terms no less favorable to the Executive
than those provided to any other senior executive of the Company, and (iii)
otherwise be in the form attached hereto as Exhibit A.

                           (ii)     During the Term of this Agreement, the
Company shall, no less frequently than semi-annually, grant or issue to the
Executive additional stock options or shares of Common Stock such that, when
taken together with all other shares of Common Stock then held by the Executive
or subject to issuance under other stock options then held by the Executive, the
Executive owns or has the right to purchase a number of shares of Common Stock
which is not less than 2% of the total number of then outstanding shares of
Common Stock (on an as converted basis). Any stock options granted to the
Executive pursuant to this paragraph

                                       4
<PAGE>   5

shall have an exercise price no greater than the fair market value per share of
Common Stock on the date of grant. Any stock options or shares of Common Stock
granted or issued to the Executive pursuant to this paragraph shall be on terms
no less favorable to the Executive than those provided to any other senior
executive of the Company.

                           (iii)    The treatment and/or conversion of the
Executive's incentive stock options upon Spin-Off shall be on terms no less
favorable to the Executive than those provided to any other senior executive of
the Company.

         3.       Term. The term of employment of Executive under this Agreement
shall be for a period of four (4) years and any extensions thereof commencing on
the Effective Date hereof and ending on the fourth (4th) anniversary thereof,
subject to earlier termination as provided in Section 4; provided, however, that
at the end of such four (4) year period and each anniversary date thereafter,
the term of this Agreement will automatically be extended for an additional year
unless, not later than six (6) months prior to the end of such four (4) year
period or one (1) year extension period, as the case may be, the Company or the
Executive shall have given notice that it or he elects not to have the term
extended. The term of this Agreement as extended and defined by this section
shall be referred to as the "Term."

         4.       Early Termination.

                  A.       For Cause.

                           (i)      Notwithstanding the foregoing, Company may
terminate the employment of Executive "for cause" (as hereinafter defined) at
any time upon written notice effective immediately. For purposes of this
Agreement, "Cause" shall mean that, prior to any termination pursuant to this
Section 4.A., Executive shall have committed:

                                    (1)      An intentional act or acts of
fraud, embezzlement or theft constituting a felony and resulting or intended to
result directly in gain or personal enrichment for Executive at the expense of
the Company; or

                                    (2)      The continued, repeated,
intentional and willful refusal to perform the duties associated with
Executive's position with the Company, which is not cured within thirty (30)
days following written notice to Executive.

For purposes of this Agreement, no act or failure to act on the part of
Executive shall be deemed "intentional" if it was due primarily to an error in
judgment or negligence, but shall be deemed "intentional" only if done or
omitted to be done by Executive not in good faith and without reasonable belief
that his action or omission was in the best interest of the Company.

         Executive shall not be deemed to have been terminated for "Cause"
hereunder unless and until there shall have been delivered to Executive a copy
of a resolution duly adopted by the affirmative vote of not less than a majority
of the Board of Directors of the Company then in office at a meeting of the
Board called and held for such purpose, after reasonable notice to Executive and
an opportunity for Executive, together with his counsel (if Executive chooses to
have counsel present at such meeting), to be heard before the Board, finding
that, in the good faith opinion of the Board, Executive had committed an act
constituting "Cause" as herein

                                       5
<PAGE>   6

defined and specifying the particulars thereof in detail. Nothing herein will
limit the right of Executive or his beneficiaries to contest the validity or
propriety of any such determination.

                           (ii)     Upon termination of Executive's employment
for cause, Company shall have no further obligation to pay any compensation to
Executive for periods after the effective date of the termination for cause,
except for Base Salary which accrued as of the termination date. In addition,
the right to exercise any vested stock option shall terminate on the 180th day
following the effective date of the termination of employment for cause.

                  B.       Change in Control. In the event of a Change in
Control (as hereinafter defined) of Company, and Executive elects, in his sole
discretion, to terminate his employment hereunder as of a date within twelve
(12) months after the Change in Control, Executive shall give Company two (2)
weeks prior written notice of such termination and Executive shall be entitled
to receive, and Company shall pay to the Executive, on the date of the
termination of employment, an amount equal to three (3) times Executive's then
yearly Base Salary and an amount equal to Executive's prorated Annual Bonus. On
such termination date, Executive shall immediately become fully vested in all of
Executive's options, restricted stock grants and/or other forms of equity-based
compensation, and his right to exercise any vested stock option and/or other
form of equity-based compensation shall terminate on the ten (10) year
anniversary following the effective date of the Executive's termination of
employment. For a period of two (2) years after the termination date, the
Company also shall maintain, at its sole expense, all medical and dental
policies and benefits provided to the Executive and his family.

         The term "Change in Control" means:

                           (i)      The acquisition by any person, entity or
"group" within the meaning of Sections 13(d)(3) or 14(d)(2) of the Securities
Exchange Act of 1934 ("34 Act") (excluding, for this purpose, Company, any of
subsidiaries, or any employee benefit plan of Company or any of its
subsidiaries) of beneficial ownership (within the meaning of Rule 13d-3
promulgated under the 34 Act) of more than forty percent (40%) of either the
then outstanding shares of common stock of Company or of the combined voting
power of Company's then outstanding voting securities entitled to vote generally
in the election of directors;

                           (ii)     Individuals who, as of the date hereof,
constitute the board of directors of Company ("Incumbent Board") cease for any
reason to constitute at least a majority of the board of directors, provided
that any individual becoming a director subsequent to the date hereof whose
election, or nomination for election by Company's shareholders, was approved by
a vote of at least a majority of the directors then comprising the Incumbent
Board shall be considered as though such individual is a member of the Incumbent
Board; or

                           (iii)    Approval of the shareholders of Company of a
merger, consolidation or other reorganization in each case, with respect to
which persons who were the shareholders of Company and options immediately prior
to such merger, consolidation or other reorganization, immediately thereafter,
do not own more than sixty percent (60%) of the combined voting power entitled
to vote generally in the election of directors of the merged, consolidated or
reorganized Company's then outstanding voting securities, or of the sale of all
or substantially all of the assets of Company; provided, however, in such event
the Change in

                                       6
<PAGE>   7

Control will be deemed to have occurred immediately prior to the merger,
consolidation or other reorganization.

                           (iv)     Gross-Up Payment.  If any of the payments
made to Executive under this Section 4.B ("payments") will be subject to the tax
imposed by Section 4999 of the Internal Revenue Code of 1986, as amended (the
"Code") the ("Excise Tax"), (and/or any similar tax that may be imposed by
federal, state or local law), the Company shall pay to the Executive an
additional amount (the "gross-up payment") equal to the sum of (x) the Excise
Tax imposed on the payments, (y) the Excise Tax imposed on the gross-up payment,
and (z) the federal, state and local income taxes imposed upon the gross-up
payment. The gross-up payment shall be made within 45 days after the date of
termination. For purposes of determining whether any of the payments will be
subject to the Excise Tax and the amount of such Excise Tax, any other payments
or benefits received or to be received by the Executive in connection with a
Change in Control or the Executive's termination (whether pursuant to the terms
of this Agreement or any other plan, arrangement or agreement with the Company,
any person whose actions result in a Change in Control or any person affiliated
with the Company or such person) shall be treated as "parachute payments" within
the meaning of Section 280G(b)(2) of the Code, and all "excess parachute
payments" within the meaning of Section 280G(b)(1) shall be treated as subject
to the Excise Tax, unless in the opinion of tax counsel selected by the Company
and acceptable to the Executive, such other payments or benefits (in whole or in
part) do not constitute parachute payments, or such excess parachute payments
(in whole or in part) represent reasonable compensation for services actually
rendered within the meaning of Section 280G(b)(4) of the Code, or are otherwise
not subject to the Excise Tax. For purposes of determining the amount of the
gross-up payment, the Executive shall be deemed to pay federal, state and local
income taxes at the highest marginal rate of federal, state and local income
taxation in the calendar year in which the gross-up payment is to be made in the
state and locality of the Executive's residence on the date of termination, net
of the maximum reduction in federal income taxes which could be obtained from
deduction of any state and local income taxes. In the event that the Excise Tax
is subsequently determined to be less than the amount used to calculate the
gross-up payment, the Executive shall repay to the Company at the time that the
reduction in Excise Tax is finally determined the portion of the gross-up
payment attributable to such reduction, plus interest on the amount of such
repayment at the rate provided in Section 7872(f)(2) of the Code. In the event
that the Excise Tax is determined to exceed the amount used to calculate the
gross-up payment (including by reason of any payment the existence or amount of
which cannot be determined at the time of the gross-up payment), the Company
shall make an additional gross-up payment in respect of such excess (plus any
interest payable with respect to such excess) at the time that the amount of
such excess is finally determined.

                  C.       Termination by Company Without Cause, by Executive
after Constructive Discharge, or Due to Executive's Death or Disability. In the
event (i) Company terminates the employment of the Executive, other than
pursuant to Section 4.A above, prior to the expiration of Term of this Agreement
as set forth in Section 3. hereof, (ii) Executive terminates his employment
after a Constructive Discharge (as defined below), or (iii) Executive's
employment terminates due to his death or Total and Permanent Disability (as
defined below), Company shall provide to the Executive or any other assignee as
provided in Section 7 below, the same rights, payments and benefits he would
have received if there had been a Change of Control as set forth in Section 4.B
above.

                                       7
<PAGE>   8

         For purposes of this Agreement, "Constructive Discharge" shall mean any
of the events set forth below which are not cured within fifteen (15) days
following written notice thereof by Executive to Company:

                           (i)      Any reduction in Base Salary;

                           (ii)     A reduction in Executive's job function,
duties or responsibilities, or a similar change in Executive's reporting
relationships;

                           (iii)    A required relocation of Executive of more
than forty (40) miles from Executive's current job location;

                           (iv)     Any material breach of any of the terms of
this Agreement by the Company; or

                           (v)      Failure by the Company to effectuate the
Spin-Off on or before May 31, 2001.

         For purposes of this Agreement, the term "Total and Permanent
Disability" shall mean the suffering by Executive of a Disability for a
continuous period in excess of one hundred eighty (180) days. A Total and
Permanent Disability shall be deemed to commence upon the expiration of such one
hundred eighty (180) day period.

                           (i)      For purposes hereof, the terms "Disabled" or
"Disability" shall mean a mental or physical condition which renders Executive
unable or incompetent to carry out the material job responsibilities, with or
without reasonable accommodation, which such Executive held or the material
duties to which Executive was assigned after the time the disability was
incurred. A determination of disability shall be made by a physician mutually
agreed upon by the Company and Executive (which agreement neither party shall
unreasonably withhold); provided that if the Executive and the Company cannot
agree on a physician, the Executive and the Company shall each select a
physician and these two shall select a third physician, whose determination as
to disability shall be binding on all parties.

         5.       No Mitigation Obligation. The Company hereby acknowledges that
it will be difficult and may be impossible (i) for Executive to find reasonably
comparable employment following the date of termination and (ii) to measure the
amount of damages which Executive may suffer as a result of termination of
employment hereunder. Accordingly, the payment of the termination compensation
by the Company to Executive in accordance with the terms of this Agreement is
hereby acknowledged by the Company to be reasonable and will be liquidated
damages, and Executive will not be required to mitigate the amount of any
payment provided for in this Agreement by seeking other employment or otherwise,
nor will any profits, income, earnings or other benefits from any source
whatsoever create any mitigation, offset, reduction or any other obligation on
the part of Executive hereunder or otherwise.

         6.       Covenants by Executive.

                  A.       InfoCure Property.

                                       8

                           (i)      Executive upon the termination of
Executive's employment for any reason and upon request shall by the Company,
shall promptly return all "Property" which had been entrusted or made available
to Executive by the Company.

                           (ii)     The term "Property" means all records,
files, memoranda, reports, price lists, customer lists, drawings, plans,
sketches, keys, codes, computer hardware and software and other property of any
kind or description prepared, used or possessed by Executive during Executive's
employment by the Company and, if applicable, any of its affiliates (and any
duplicates of any such property) together with any and all information, ideas,
concepts, discoveries, and inventions and the like conceived, made, developed or
acquired at any time by Executive individually or, with others during

         3.       CONSENT TO CERTAIN TRANSACTIONS. Subject to the terms and

                  3.1      NAME CHANGE. From and after the Effective Date,
         FINOVA shall be deemed to have consented to the name change by InfoCure
         Corporation to VitalWorks Inc.; provided, that, (i) InfoCure
         Corporation shall provide FINOVA with at least ten (10) Business Days'
         prior written notice of the consummation of such name change and (ii)
         InfoCure Corporation and its Subsidiaries shall at any time and from
         time to time take, do, execute, acknowledge and deliver, or cause to be
         taken, done, executed, acknowledged and delivered, all such acts,
         agreements, documents and instruments as may be required by FINOVA to
         effectuate such name change and preserve the priority and perfection of
         the Liens granted to FINOVA under the Collateral Documents, including,
         without limitation, (i) the execution and delivery of UCC financing
         statements and amendments to existing UCC financing statements, (ii)

         executed in blank and irrevocable proxies coupled with interest. From
         and after the effective date of such name change, all reference to

         Documents shall be deemed to have been amended to refer to InfoCure
         Corporation, after giving effect to such name change, or VitalWorks
         Inc., as the context may dictate. The failure of any Obligor to comply
         with the terms and conditions of this Section 3.1 shall constitute an

         Distribution Transaction Documents. Upon the consummation of such
         transactions, but subject to Section 17 hereof, FINOVA shall (i) be
         deemed to have released its Lien on the assets and other Property of
         PracticeWorks and its Subsidiaries solely as such Lien secures

         specifically excluding any obligations, liabilities and indebtedness
         evidenced or to be evidenced by the PracticeWorks Credit Facility) and
         to have released such Persons from the Loan Documents (except to the
         extent any such provisions (including, without limitation,
         indemnification provisions and representations, warranties and
         covenants) expressly survive the termination of such Loan Documents or
         the release of such Persons) and (ii) execute and deliver to Borrowers
         and their Subsidiaries, upon request and at Borrowers' sole cost and
         expense, such agreements, documents and instruments reasonably
         necessary to evidence the release of the security interests in and
         Liens on the assets and other Property of PracticeWorks under the
         credit facilities evidenced by the Loan Agreement.

         Systems and their respective Subsidiaries shall at any time and from
         time to time take, do, execute, acknowledge and deliver, or cause to be
         taken, done, executed, acknowledged and delivered, all such acts,
         agreements, documents and instruments as may be required by FINOVA to
         effectuate the reorganization, the name change and the other related
         transactions, and preserve the priority and perfection of the Liens
         granted to FINOVA under the Collateral Documents, including, without
         limitation, (i) the execution and delivery of UCC financing statements
         and amendments to existing UCC financing statements, (ii) the delivery
         to FINOVA of copies of all resolutions and all recorded agreements,
         documents and instruments filed with any Governmental Body (including,

         Authority, the New Hampshire Secretary of State and the Kansas
         Secretary of State) to effectuate such transactions, certified by a

         date of such transactions, all references to InfoCure Systems
         contained in the Loan Agreement or the other Loan Documents shall be

         giving effect to such transactions as the context may dictate. The
         failure of any Obligor to comply with the terms and conditions of this
         Section 3.3 shall constitute an immediate Event of Default, without
         further action or notice by or on behalf of FINOVA or any other Person.

                  3.4      PRACTICEWORKS CREDIT FACILITY. From and after the
         Effective Date, FINOVA shall be deemed to have consented to the

         deliver, or cause to be taken, done, executed, acknowledged and
         delivered, all such acts, agreements, documents and instruments as may
         be required by FINOVA to effectuate such mergers, and preserve the
         priority and perfection of the Liens granted to FINOVA under the
         Collateral Documents, including, without limitation, (a) the execution
         and delivery of UCC financing statements and amendments to existing UCC

         satisfactory to counsel for FINOVA.

The date on which all of the conditions set forth in this Section 4 shall have
satisfied or waived in writing by FINOVA shall be deemed to be the "Effective

Amendment by Borrowers and their respective Subsidiaries shall constitute a
representation and warranty by such Persons to FINOVA that the conditions set

accrued and unpaid interest through December 31, 2000, is $935,000.09 (less

warrant to FINOVA that neither any Borrower nor any Subsidiary of any Borrower
voluntarily or involuntarily is consummating the transactions contemplated
hereunder or any of the Related Transaction Documents, or making any transfer or
incurring any obligation contemplated thereby, with actual intent to hinder,
delay or defraud any entity to which any Borrower or any such Subsidiary was or
became, on or after the Effective Date, indebted.

         7.       COSTS AND EXPENSES. Each Borrower jointly and severally agrees
to reimburse FINOVA for all fees and expenses incurred in the preparation,

Subsidiary of each Borrower (other than PracticeWorks and its Subsidiaries after
giving effect to the Distribution) hereby ratifies and confirms its liabilities,
obligations and agreements under the Existing Loan Agreement and the other Loan

thereby and the guarantees made by such Persons, as applicable, and acknowledges
that (i) it has no defenses, claims or set-offs to the enforcement by FINOVA of
such liabilities, obligations and agreements, (ii) FINOVA has fully performed
all obligations to such Persons which FINOVA may have had or has on and as of
the date hereof and (iii) other than as specifically set forth herein, FINOVA
does not waive, diminish or limit any term, condition or covenant contained in
the Existing Loan Agreement, as amended, or any of the other Loan Documents.
FINOVA's agreement to the terms of this Second Amendment shall not be deemed to
establish or create a custom or course of dealing among FINOVA, Borrowers and
their Subsidiaries.

         9.       COUNTERPARTS. This Second Amendment may be executed in one or
more counterparts, each of which shall be deemed an original, and all of which,
when taken together, shall constitute one and the same instrument.

         10.      FURTHER ASSURANCES. Each Borrower and each Subsidiary of each
Borrower covenants and agrees that it will at any time and from time to time do,
execute, acknowledge and deliver, or will cause to be done, executed,
acknowledged and delivered, all such further acts, documents and instruments as
reasonably may be required by FINOVA in order to effectuate fully the intent of
this Second Amendment.

         11.      SEVERABILITY. If any term or provision of this Second
Amendment or the application thereof to any party or circumstance shall be held
to be invalid, illegal or unenforceable in any respect by a court of competent
jurisdiction, the validity, legality and enforceability of the remaining terms
and provisions of this Second Amendment shall not in any way be affected or
impaired thereby, and the affected term or provision shall be modified to the
minimum extent permitted by law so as most fully to achieve the intention of
this Second Amendment.

equitable remedy under any statute, regulation or common law principle arising
from or in connection with the Contribution,

                                       29
<PAGE>   30

the ISI Merger, the Distribution and/or the negotiation, preparation, execution,
delivery, performance, administration and enforcement of any agreement, document
or instrument executed in connection therewith, including, without limitation,
this Second Amendment and the Distribution Transaction Documents (including,
without limitation, for any failure of the Distribution to be consummated or
otherwise of full force and effect or of the Contribution, the ISI Merger and/or
the Distribution to qualify as a tax-free reorganization under Section
368(a)(1)(D) of the Code or to otherwise qualify for non-recognition treatment
under the Code and/or the Distribution to qualify as a tax-free transaction
described in Section 355 of the Code). The foregoing indemnity shall survive the
payment in full of Borrowers' Obligations and the termination of the Loan
Agreement.

         14.      GOVERNING LAW. This Second Amendment shall be governed by and
construed in accordance with the internal laws (without regard to conflict of
laws provisions) and decisions of the State of Arizona.

         15.      NO NOVATION. Nothing herein is intended or shall be deemed to
constitute a novation of the Loan Agreement or any of the other Loan Documents.

         16.      ADDITIONAL AGREEMENTS. Reference hereby is made to that
certain Letter Agreement dated as of July 31, 2000 (the "Letter Agreement")
among Borrowers and FINOVA. Borrowers represent and warrant to FINOVA that, as
of the Second Amendment Effective Date, the aggregate outstanding principal
balance of the Notes (as defined in the Letter Agreement ) is $12,175,391.62.
Borrowers agree and acknowledge that (i) Borrowers shall make a mandatory
prepayment of the Loans upon receipt of any amounts due thereunder and, without
limiting the foregoing, on the currently scheduled maturity date of each such
Note in an amount equal to the then outstanding principal balance of such Notes,
plus all accrued and unpaid interest thereon, and (ii) such Letter Agreement
remains in full force and effect, and any default by any Borrower thereunder or
any failure of any Borrower to comply with the terms, conditions, agreements and
covenants therein contained shall constitute an immediate Event of Default,
without notice or other action by or on behalf of FINOVA or any other Person.
Each Borrower represents and warrants that the material economic and other terms
of such Notes are described on Schedule I hereto, which schedule sets forth the
payee and the maker under, and the original principal amount, the current
outstanding principal amount, the interest rate and the maturity date of, such
Notes.

         17.      UNWIND AGREEMENT. If for any reason at any time the
Distribution shall fail, shall fail to be consummated or shall be unwound,
terminated, repealed or otherwise not of full force and effect, then the
Borrowers agree, and agree to cause their Subsidiaries, to (a) take such action
as FINOVA may require, if any, in its sole and absolute discretion, to unwind or
otherwise amend and modify the transactions contemplated by this Second
Amendment and/or evidenced by the PracticeWorks Credit Facility and (b) execute
and deliver such agreements, documents and instruments, and procure the issuance
of such legal opinions, in each case as FINOVA may require in its sole and
absolute discretion. The Borrowers acknowledge that the agreements and covenants
contained in this Section 17 constitute a material inducement to FINOVA's
agreement to execute and deliver, and consent to the transactions contemplated
by, this Second Amendment. All costs,

                                       30
<PAGE>   31

expenses and fees incurred by FINOVA and its representatives under this Section
17 shall be borne solely by the Borrowers, on a joint and several basis, and
shall be due and payable by Borrowers to FINOVA on demand. The failure of any
Borrower or any Subsidiary of any Borrower, or any debtor, guarantor, borrower
or other obligor under the PracticeWorks Credit Facility, to comply with the
terms and conditions of this Section 17 shall constitute an immediate Event of
Default, without further action or notice by or on behalf of FINOVA or any other
Person.
