referred to as the "EMPLOYER"),  and John T. Larimer, an individual (hereinafter
referred to as the "EMPLOYEE");

                                   WITNESSETH:

         WHEREAS, the  EMPLOYEE  is  currently  employed  as  the  President and
Managing Officer of the EMPLOYER;

         WHEREAS,  as a result of the skill,  knowledge  and  experience  of the

of the EMPLOYEE as the President and Managing Officer of the EMPLOYER;

         WHEREAS, the EMPLOYEE desires to continue to serve as the President and
Managing Officer of the EMPLOYER; and

         WHEREAS,  the  EMPLOYEE  and the  EMPLOYER  desire  to enter  into this
AGREEMENT to set forth the terms and conditions of the  employment  relationship
between the EMPLOYER and the EMPLOYEE.

         NOW,  THEREFORE,  in consideration of the premises and mutual covenants
herein contained, the EMPLOYER and the EMPLOYEE hereby agree as follows:

1.  Employment  and Term.  Upon the terms and subject to the  conditions of this
AGREEMENT,  the EMPLOYER  hereby employs the EMPLOYEE,  and the EMPLOYEE  hereby
accepts employment,  as the President and Managing Officer of the EMPLOYER.  The
term of this AGREEMENT shall commence on the date hereof, and shall end on March
31, 2003  (hereinafter  referred to as the "TERM").  In March of each year,  the
Board of Directors of the EMPLOYER shall review the EMPLOYEE's  performance  and
record the results of such review in the minutes of the Board of Directors. This
AGREEMENT  shall not be  renewed  or  extended  without a taking of  affirmative
action by the Board of  Directors  of the  EMPLOYER  to cause  such  renewal  or
extension.  Any such  extension  shall be subject to the written  consent of the
EMPLOYEE.

2.       Duties of EMPLOYEE.

         (a) General  Duties and  Responsibilities.  The EMPLOYEE shall serve as
the President and Managing Officer of the EMPLOYER.  Subject to the direction of

for the  general  management  and  control of the  business  and  affairs of the
EMPLOYER  and shall  perform  all duties  and shall  have all  powers  which are

<PAGE>
commonly  incident to the office of  President  and  Managing  Officer or which,
consistent  therewith,  are  delegated  to him by the Board of  Directors.  Such
duties  shall  include,  but not be limited  to,  (1)  managing  the  day-to-day
operations of the  EMPLOYER,  (2) managing the efforts of the EMPLOYER to comply
with  applicable  laws and  regulations,  (3)  marketing of the EMPLOYER and its
services,  (4) supervising other employees of the EMPLOYER, (5) providing prompt

Board of Directors of the EMPLOYER concerning the strategies, capital structure,
tactics, and general operations of the EMPLOYER.

         (b)  Devotion  of Entire  Time to the  Business  of the  EMPLOYER.  The
EMPLOYEE shall devote his entire  productive time,  ability and attention during
normal  business hours  throughout  the TERM to the faithful  performance of his
duties  under this  AGREEMENT.  The EMPLOYEE  shall not  directly or  indirectly
render any  services of a business,  commercial  or  professional  nature to any
person or organization other than the EMPLOYER and Market Financial  Corporation
without the prior  written  consent of the Board of Directors  of the  EMPLOYER;
provided,  however,  that the EMPLOYEE shall not be precluded from (i) vacations
and other leave time in  accordance  with Section 3(d) hereof;  (ii)  reasonable
participation in community, civic, charitable or similar organizations; or (iii)
the pursuit of personal  investments which do not interfere or conflict with the
performance  of the EMPLOYEE's  duties to the EMPLOYER.  Nothing in this section
shall limit the  EMPLOYEE's  right to invest in  securities of any business that
does not  provide  services  or  products  of the type or  competing  with those
provided by the EMPLOYER or its subsidiaries or affiliates.

3.       Compensation, Benefits and Reimbursements.

         (a) Salary. The EMPLOYEE shall receive during the TERM an annual salary
payable in equal  installments  not less often than monthly.  The amount of such
annual  salary shall be $109,750  until changed by the Board of Directors of the
EMPLOYER in accordance with Section 3(b) of this AGREEMENT.

         (b) Annual Salary  Review.  In March of each year  throughout the TERM,
the annual salary of the EMPLOYEE shall be reviewed by the Board of Directors of
the EMPLOYER and shall be set at an amount not less than $109,750 based upon the
EMPLOYEE's  individual  performance and the overall  profitability and financial
condition of the EMPLOYER (hereinafter referred to as the "ANNUAL REVIEW").  The
results of the ANNUAL  REVIEW  shall be reflected in the minutes of the Board of
Directors of the EMPLOYER.

         (c) Employee  Benefit  Program.  During the TERM, the EMPLOYEE shall be
entitled to participate in all formally  established  employee  benefit,  bonus,
pension and profit-sharing plans and similar programs that are maintained by the
EMPLOYER from time to time, and all employee benefit plans or programs hereafter
adopted in writing by the Board of Directors of the  EMPLOYER,  for which senior
management  personnel are eligible  including any employee stock ownership plan,
stock option plan or other stock benefit plan (hereinafter collectively referred
to as the  "BENEFIT  PLANS").  Notwithstanding  any  statement  to the  contrary

                                       2
<PAGE>

contained elsewhere in this Agreement, the EMPLOYER may discontinue or terminate
at any time any such BENEFIT PLANS,  now existing or hereafter  adopted,  to the
extent  permitted  by the  terms of such  plans and  shall  not be  required  to
compensate the EMPLOYEE for such discontinuance or termination.

         (d) Vacation and Sick Leave.  The EMPLOYEE  shall be entitled,  without
loss of pay, to be absent  voluntarily  from the performance of his duties under
this AGREEMENT, in accordance with the policies periodically  established by the
Board of  Directors  of the  EMPLOYER  for senior  management  officials  of the
EMPLOYER.  The  EMPLOYEE  shall  not  be  entitled  to  receive  any  additional
compensation  from the  EMPLOYER  in the event of his  failure  to take the full
allotment  of vacation  time in any  calendar  year.  In the event that any sick
leave time shall not have been used during any calendar  year,  such leave shall
accrue to subsequent  calendar years, only to the extent authorized by the Board
of Directors of the EMPLOYER. Upon termination of employment, the EMPLOYEE shall
not be entitled to receive any  additional  compensation  from the  EMPLOYER for
unused sick leave.

4.       Termination of Employment.

         (a) General.  In addition to the  termination  of the employment of the
EMPLOYEE upon the  expiration of the TERM,  the employment of the EMPLOYEE shall
terminate at any other time during the TERM upon the delivery by the EMPLOYER of
written notice of employment  termination to the EMPLOYEE.  Without limiting the
generality of the foregoing sentence, the following  subparagraphs (i), (ii) and
(iii) of this Section 4(a) shall govern the  obligations  of the EMPLOYER to the
EMPLOYEE upon the occurrence of the events described in such subparagraphs:

                  (i) Termination for JUST CAUSE. In the event that the EMPLOYER
terminates  the  employment  of the  EMPLOYEE  during  the TERM  because  of the
EMPLOYEE's personal  dishonesty,  incompetence,  willful  misconduct,  breach of
fiduciary  duty involving  personal  profit,  intentional  failure or refusal to
perform  the duties and  responsibilities  assigned in this  AGREEMENT,  willful
violation of any law, rule,  regulation or final  cease-and-desist  order (other
than traffic  violations  or similar  offenses),  conviction  of a felony or for
fraud or  embezzlement,  or material  breach of any provision of this  AGREEMENT
(hereinafter  collectively  referred to as "JUST CAUSE"), the EMPLOYEE shall not
receive,  and shall have no right to receive, any compensation or other benefits
for any period after such termination.

                  (ii) Termination  after CHANGE OF CONTROL.  In the event that,
before  the  expiration  of the TERM and in  connection  with or within one year
after a CHANGE OF CONTROL (as  defined  hereinafter)  of the  EMPLOYER or Market
Financial Corporation,  (A) the employment of the EMPLOYEE is terminated for any
reason other than JUST CAUSE before the  expiration of the TERM, (B) the present
capacity or  circumstances  in which the  EMPLOYEE is  employed  are  materially
changed   before   the   expiration   of  the  TERM,   or  (C)  the   EMPLOYEE's
responsibilities,  authority, compensation or other benefits provided under this
AGREEMENT are materially reduced, then the following shall occur:

                                       3
<PAGE>

                (I)  The EMPLOYER shall promptly pay to the EMPLOYEE or  to  his
beneficiaries, dependents or estate an amount equal to the sum of (1) the amount
of compensation to which the EMPLOYEE would be entitled for the remainder of the
TERM under this  AGREEMENT,  plus (2) the difference  between (x) the product of
three,  multiplied by the greater of the annual salary set forth in Section 3(a)
of this  AGREEMENT or the annual  salary  payable to the EMPLOYEE as a result of
any ANNUAL REVIEW,  less (xx) the amount paid to the EMPLOYEE pursuant to clause
(1) of this subparagraph (I);

                (II)  The  EMPLOYEE,  his  dependents,  beneficiaries and estate
shall  continue  to be covered  under all BENEFIT  PLANS of the  EMPLOYER at the
EMPLOYER's  expense as if the EMPLOYEE were still  employed under this AGREEMENT
until  the  earliest  of the  expiration  of the TERM or the  date on which  the
EMPLOYEE  is  included  in  another  employer's  benefit  plans  as a  full-time
employee; and

                (III)  The EMPLOYEE shall not be required to mitigate the amount
of any payment  provided for in this  AGREEMENT by seeking  other  employment or
otherwise,  nor shall any amounts received from other employment or otherwise by
the EMPLOYEE  offset in any manner the  obligations  of the EMPLOYER  hereunder,
except as specifically stated in subparagraph (II).

                  In the event that payments  pursuant to this  subsection  (ii)
would result in the  imposition of a penalty tax pursuant to Section  280G(b)(3)
of  the  Internal  Revenue  Code  of  1986,  as  amended,  and  the  regulations
promulgated thereunder (hereinafter collectively referred to as "SECTION 280G"),
such  payments  shall be reduced to the maximum  amount  which may be paid under
SECTION 280G without exceeding such limits. Payments pursuant to this subsection
also may not exceed the limit set forth in Regulatory Bulletin 27a of the Office
of Thrift Supervision.

                  (iii) Termination Without CHANGE OF CONTROL. In the event that
the  employment of the EMPLOYEE is terminated  before the expiration of the TERM
other than (A) for JUST CAUSE or (B) in connection with or within one year after
a CHANGE OF CONTROL, the EMPLOYER shall be obligated to continue (1) to pay on a
monthly basis to the EMPLOYEE,  his designated  beneficiaries or his estate, his
annual salary  provided  pursuant to Section 3(a) or (b) of this AGREEMENT until
the expiration of the TERM and (2) to provide to the EMPLOYEE, at the EMPLOYER's
expense,  health, life,  disability,  and other benefits  substantially equal to
those  being  provided  to  the  EMPLOYEE  at the  date  of  termination  of his
employment until the earliest to occur of the expiration of the TERM or the date
the EMPLOYEE becomes employed  full-time by another employer.  In the event that
payments  pursuant to this subsection  (iii) would result in the imposition of a
penalty tax  pursuant to SECTION  280G,  such  payments  shall be reduced to the
maximum  amount which may be paid under  SECTION 280G  without  exceeding  those
limits.  Payments  pursuant to this subsection also may not exceed the limit set
forth in Regulatory Bulletin 27a of the Office of Thrift Supervision.

                                       4
<PAGE>

         (b) Death of the EMPLOYEE.  The TERM automatically  terminates upon the
death of the EMPLOYEE.  In the event of such death, the EMPLOYEE's  estate shall
be entitled to receive the compensation due the EMPLOYEE through the last day of
the calendar month in which the death  occurred,  except as otherwise  specified
herein.

         (c) "Golden Parachute" Provision.   Any  payments  made to the EMPLOYEE
pursuant to this  AGREEMENT or  otherwise  are subject to and  conditioned  upon
their  compliance  with  12  U.S.C.ss.1828(k)  and any  regulations  promulgated
thereunder.

         (d) Definition of "CHANGE OF CONTROL". A "CHANGE OF CONTROL" shall mean
any one of the following  events;  (i) the  acquisition of ownership or power to
vote more  than 25% of the  voting  stock of the  EMPLOYER  or Market  Financial
Corporation;  (ii) the  acquisition  of the ability to control the election of a
majority of the directors of the EMPLOYER or Market Financial Corporation; (iii)
during any period of two consecutive years,  individuals who at the beginning of
such  period  constitute  the  Board of  Directors  of the  EMPLOYER  or  Market
Financial  Corporation  cease for any reason to constitute  at least  two-thirds
thereof; provided, however, that any individual whose election or nomination for
election  as a member  of the  Board of  Directors  of the  EMPLOYER  or  Market
Financial  Corporation  was  approved  by a vote of at least  two-thirds  of the
directors then in office shall be considered to have continued to be a member of
the Board of Directors of the EMPLOYER or Market Financial Corporation;  or (iv)
the acquisition by any person or entity of "conclusive  control" of the EMPLOYER
within the meaning of 12 C.F.R. ss.574.4(a), or the acquisition by any person or
entity of "rebuttable control" within the meaning of 12 C.F.R.  ss.574.4(b) that
has not been rebutted in accordance with 12 C.F.R. ss.574.4(c).  For purposes of
this  paragraph,  the term  "person"  refers to an  individual  or  corporation,
partnership, trust, association, or other organization, but does not include the
EMPLOYEE and any person or persons with whom the EMPLOYEE is "acting in concert"
within the meaning of 12 C.F.R. Part 574.

5.       Special  Regulatory   Events.     Notwithstanding  Section  4  of  this
AGREEMENT,  the  obligations of the EMPLOYER to the EMPLOYEE shall be as follows
in the event of the following circumstances:

         (a) If the EMPLOYEE is suspended  and/or  temporarily  prohibited  from
participating in the conduct of the EMPLOYER's  affairs by a notice served under
section  8(e)(3) or (g)(1) of the Federal  Deposit  Insurance  Act  (hereinafter
referred to as the "FDIA"),  the  EMPLOYER's  obligations  under this  AGREEMENT
shall be suspended as of the date of service of such  notice,  unless  stayed by
appropriate  proceedings.  If the  charges  in the  notice  are  dismissed,  the
EMPLOYER  may,  in  its  discretion,  pay  the  EMPLOYEE  all  or  part  of  the
compensation withheld while the obligations in this AGREEMENT were suspended and
reinstate, in whole or in part, any of the obligations that were suspended;

         (b) If the  EMPLOYEE  is removed  and/or  permanently  prohibited  from
participating in the conduct of the EMPLOYER's  affairs by an order issued under
Section  8(e)(4) or (g)(1) of the FDIA,  all  obligations  of the EMPLOYER under

                                       5
<PAGE>

this AGREEMENT shall terminate as of the effective date of such order; provided,
however,  that  vested  rights of the  EMPLOYEE  shall not be  affected  by such
termination;

         (c) If the EMPLOYER is in default, as defined in section 3(x)(1) of the
FDIA, all  obligations  under this AGREEMENT  shall  terminate as of the date of
default;  provided,  however,  that vested  rights of the EMPLOYEE  shall not be
affected;

         (d) All obligations under this AGREEMENT shall be terminated, except to
the  extent  of a  determination  that the  continuation  of this  AGREEMENT  is
necessary  for the continued  operation of the EMPLOYER,  (i) by the Director of
the Office of Thrift Supervision  (hereinafter referred to as the "OTS"), or his
or her  designee  at the time that the  Federal  Deposit  Insurance  Corporation
enters into an agreement to provide  assistance  to or on behalf of the EMPLOYER
under  the  authority  contained  in  Section  13(c)  of the FDIA or (ii) by the
Director of the OTS, or his or her designee, at any time the Director of the OTS
approves a supervisory  merger to resolve  problems  related to the operation of
the EMPLOYER or when the EMPLOYER is determined by the Director of the OTS to be
in an unsafe or unsound condition. No vested rights of the EMPLOYEE shall not be
affected by any such action; and

         (e)  The provisions of this Section 5 are governed by the  requirements
of 12 C.F.R.ss.563.39(b)  and in the event that any statements in this Section 5
are  inconsistent  with  12  C.F.R.ss.563.39(b),  the  provisions  of 12  C.F.R.
ss.563.39(b) shall be controlling.

6.  Consolidation,  Merger or Sale of Assets.  Nothing in this  AGREEMENT  shall
preclude the EMPLOYER or Market Financial  Corporation from consolidating  with,
merging  into, or  transferring  all, or  substantially  all, of their assets to
another  corporation  that  assumes all of their  obligations  and  undertakings
hereunder.  Upon such a  consolidation,  merger or transfer of assets,  the term
"EMPLOYER" as used herein, shall mean such other corporation or entity, and this
AGREEMENT shall continue in full force and effect.

7.  Confidential   Information.   The  EMPLOYEE  acknowledges  that  during  his
employment he will learn and have access to confidential  information  regarding
the EMPLOYER and its customers and businesses. The EMPLOYEE agrees and covenants
not to disclose or use for his own  benefit,  or the benefit of any other person
or entity, any confidential  information,  unless or until the EMPLOYER consents
to such disclosure or use or such information is otherwise legally in the public
domain.  The EMPLOYEE shall not knowingly disclose or reveal to any unauthorized
person any confidential  information relating to the EMPLOYER, its subsidiaries,
or affiliates,  or to any of the  businesses  operated by them, and the EMPLOYEE
confirms  that  such  information  constitutes  the  exclusive  property  of the
EMPLOYER.  The EMPLOYEE shall not otherwise knowingly act or conduct himself (a)
to the material detriment of the EMPLOYER, its subsidiaries,  or affiliates,  or
(b) in a manner which is inimical or contrary to the interests of the EMPLOYER.

8. Non-assignability. Neither this AGREEMENT nor any right or interest hereunder
shall be assignable by the EMPLOYEE,  his beneficiaries or legal representatives
without the EMPLOYER's prior written consent; provided, however, that nothing in

                                       6
<PAGE>

this Section 8 shall preclude (a) the EMPLOYEE from designating a beneficiary to
receive any benefits  payable  hereunder  upon his death,  or (b) the executors,
administrators,  or other legal  representatives  of the  EMPLOYEE or his estate
from assigning any rights hereunder to the person or persons entitled thereto.

9. No Attachment.  Except as required by law, no right to receive  payment under
this AGREEMENT shall be subject to anticipation,  commutation, alienation, sale,
assignment,  encumbrance,  charge,  pledge  or  hypothecation  or to  execution,
attachment,  levy, or similar process of assignment by operation of law, and any
attempt, voluntary or involuntary, to effect any such action shall be null, void
and of no effect.

10. Binding  Agreement.   This  AGREEMENT  shall  be   binding  upon,  and inure
to  the   benefit  of,  the  EMPLOYEE  and   the  EMPLOYER  and  its  respective
permitted successors and assigns.

11. Amendment of  AGREEMENT.   This AGREEMENT  may  not  be modified or amended,
except by an instrument in writing signed by the parties hereto.

12. Waiver.  No term or condition of this AGREEMENT shall be deemed to have been
waived,  nor shall there be an estoppel against the enforcement of any provision
of this AGREEMENT,  except by written  instrument of the party charged with such
waiver or estoppel.  No such written waiver shall be deemed a continuing waiver,
unless specifically stated therein, and each waiver shall operate only as to the
specific term or condition waived and shall not constitute a waiver of such term
or  condition  for the future or as to any act other  than the act  specifically
waived.

13.  Severability.  If, for any reason,  any provision of this AGREEMENT is held
invalid, such invalidity shall not affect the other provisions of this AGREEMENT
not held so invalid,  and each such other  provision  shall,  to the full extent
consistent  with  applicable  law,  continue in full force and  effect.  If this
AGREEMENT  is held  invalid  or cannot  be  enforced,  then any prior  AGREEMENT
between the EMPLOYER  (or any  predecessor  thereof)  and the EMPLOYEE  shall be
deemed  reinstated to the full extent permitted by law, as if this AGREEMENT had
not been executed.

14.  Headings.  The headings of the paragraphs  herein are  included  solely for
convenience of reference and shall not control the meaning or  interpretation of
any of the provisions of this AGREEMENT.

15.  Governing  Law.   This   AGREEMENT  has  been  executed  and  delivered  in
the State of Ohio and its validity, interpretation, performance, and enforcement
shall be governed  by the laws of this State of Ohio,  except to the extent that
federal law is governing.

16.  Effect  of  Prior  Agreements.     This   AGREEMENT   contains  the  entire
understanding  between the parties hereto and  supercedes  any prior  employment
agreement  between  the  EMPLOYER or any  predecessor  of the  EMPLOYER  and the
EMPLOYEE.

     NOW, THEREFORE, in consideration of the covenants, promises and
representations set forth herein, and for other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, the parties agree
as follows:

1.   Forward Merger. Any references in the Merger Agreement to Merger Sub
     merging with and into Company are hereby modified such that Company will
     merge with and into Merger Sub, with Merger Sub being the surviving
     corporation. All references in the Merger Agreement to the Surviving
     Corporation shall be deemed to refer to Merger Sub.

2.   Articles of Incorporation; Bylaws. The first two (2) paragraphs of Section
     2.4 of the Merger Agreement shall be and are hereby amended to read as
     follows:

<PAGE>

     "At the Effective Time, the Articles of Incorporation of the Surviving
Corporation, as in effect immediately prior to the Effective Time, shall be the
Articles of Incorporation of the Surviving Corporation and thereafter shall
continue to be its Articles of Incorporation (until amended as provided under
Colorado Law).

     The Bylaws of the Surviving Corporation, as in effect immediately prior to
the Effective Time, shall be the Bylaws of the Surviving Corporation and
thereafter shall continue to be its bylaws (until amended as provided therein
and under Colorado Law)."

3.   Waiver of Covenant. Company waives Parent's compliance with the covenant of
     Parent set forth in Section 5.9.

4.   Provision of Additional Loan by Parent to Company. The parties agree to
     promptly amend the existing loan agreement and related documents
     (collectively, the "Loan Documents") to provide for an additional advance
     by Parent of One Hundred Thousand and No/100 Dollars ($100,000.00) to
     Company and Subsidiary to be used for general working capital purposes,
     which advance shall be made on or before January 15, 2001. Upon such
     advance, the total aggregate principal loan balance outstanding will be

     further amended to delete Sections 8.1.H. and 8.1.I. in their entirety.

6.   Termination Date. Section 8.1.B. of this Agreement shall be and hereby is
     amended to read in its entirety as follows:

     "B. By either Company or Parent if the Merger shall not have been
consummated for any reason (i) by March 31, 2001, if the Spin-off has occurred
or (ii) by April 30, 2001, if the Spin-off has not occurred; provided, however,
that the right to terminate this Agreement under this Section 8.1.B. shall not
be available to any party whose action or failure to act has been a principal
cause of or resulted in the failure of the Merger to occur on or before such
date and such action or failure to act constitutes a breach of this Agreement;"

7.   PracticeWorks Spin-off. The Merger Agreement hereby is amended by
     inserting the following as a new Section 2.12:

     2.12 PracticeWorks Spin-off. If the PracticeWorks Spin-off is completed on

          A. Assignment of Merger Sub Stock and Agreement. On the Spin-off Date,
InfoCure Corporation shall (i) assign to PracticeWorks all of the outstanding
shares of capital stock of Merger Sub; (ii) assign to PracticeWorks all of
InfoCure Corporation's rights under this Agreement and (iii) cause PracticeWorks
to assume from InfoCure Corporation all of InfoCure Corporation's obligations
under this Agreement, except its obligations to provide shares of common stock,

<PAGE>

$.001 par value per share, of InfoCure ("InfoCure Common Stock") pursuant to
Section 2.5.A.(ii) hereof; provided, however, that such assignment and
assumption shall not relieve InfoCure Corporation from any liability to the
Company for any breach of this Agreement by InfoCure Corporation prior to the
Spin-off Date. From and after the Spin-off Date, all references to "Parent" in
this Agreement shall mean PracticeWorks, except where the context clearly
requires otherwise.

          B. PracticeWorks Representations and Warranties. Within ten (10)
business days after the Spin-off Date, PracticeWorks shall deliver to the
Company a disclosure schedule meeting the requirements described in the first

8.   Post Spin-off Merger Consideration. Effective on the Spin-off Date, Section
     2.5.A. of the Merger Agreement shall be and hereby is amended to read in
     its entirety as follows:

     "A. Conversion of Company Common Stock. Each share of common stock, $.001
par value per share, of Company (the "Company Common Stock") issued and
outstanding immediately prior to the Effective Time, other than any shares of
Company Common Stock to be canceled pursuant to Section 2.5.B. and any
Dissenting Shares (as defined and to the extent provided in Section 2.5.I.),

Section 2.5.F.) into the right to receive (i) 0.017183 of a share, unless
adjusted as provided for herein, of Parent Common Stock ("Common Exchange
Ratio"); (ii) 0.06873 of a share of InfoCure Common Stock and (iii) 0.07558 of a

subject to all of the conditions relating to adjustment, conditional stock and
dissenters rights, etc. as set forth in Sections 2.5 (E., G., and I.), 2.6, 2.7
and 2.8 hereof, as such sections would apply to InfoCure's issuance of its
common stock if the Spin-off had not occurred. In addition, the issuance of
InfoCure Common Stock pursuant to this Section 2.5.A. will not apply to
fractional shares of InfoCure Common Stock, but in lieu thereof, the holder of
any shares of Company Common Stock who would otherwise be entitled to receive a
fraction of a share of InfoCure Common Stock shall receive cash in an amount
equal to the value of such fractional share, which shall be equal to the
fraction of a share of InfoCure Common Stock that would otherwise be issued
multiplied by Four 93/100 Dollars ($4.93)."

9.   Post Spin-off Fractional Shares. Effective on the Spin-off Date, the last
     sentence of Section 2.5.F. of the Merger Agreement shall be and hereby is
     amended to read in its entirety as follows:

     "No fractional shares of Parent Common Stock or Parent Preferred Stock will
be issued in connection with the Merger, but in lieu thereof, the holder of any
shares of Company Common Stock who would otherwise be entitled to receive (i) a
fraction of a share of Parent Common Stock shall receive cash in an amount equal
to the value of such fractional share, which shall be equal to the fraction of a
share of Parent Common Stock that would otherwise be issued multiplied by

<PAGE>

Nineteen and 72/100 Dollars ($19.72) or (ii) a fraction of a share of Parent
Preferred Stock shall receive cash in an amount equal to the value of such
fractional share, which shall be equal to the fraction of a share of Parent
Preferred Stock that would otherwise be issued multiplied by Five and 44/100
Dollars ($5.44)."

10.  Post Spin-off Odd Lot Cash-Out. Effective on the Spin-off Date, Section
     2.5.H. of the Merger Agreement shall be and hereby is amended to read in
     its entirety as follows:

     "H. Odd Lot Cash-Out. Notwithstanding Sections 2.5.A. and 2.5.F. above, any
holder, owning in the aggregate, one hundred (100) or fewer shares of Company
Common Stock ("Odd Lot Shareholder"), shall instead receive cash in an amount
equal to 75/100 Dollars ($0.75) per share of Company Common Stock held by such
Odd Lot Shareholder."

11.  Post Spin-off Proxy Statement/Registration Statement; Shareholder Approval.
     Effective on the Spin-off Date, Section 6.1.D. of the Merger Agreement
     shall be and hereby is amended to read in its entirety as follows:

     "D. Proxy Statement/ Registration Statement; Shareholder Approval.
Following the execution of this Agreement, InfoCure Corporation, Parent, Merger
Sub and the Company will mutually cooperate to prepare and file with the SEC a
preliminary proxy statement relating to the Merger (the "Proxy Statement") and
InfoCure Corporation and Parent will prepare and file with the SEC the
Registration Statement in which the Proxy Statement will be included as a
prospectus. Each of InfoCure Corporation, Parent, Merger Sub and the Company
will respond to any comments of the SEC and will use its best efforts to have
the Registration Statement declared effective under the Securities Act as
promptly as practicable after such filing and when the Registration Statement is
declared effective by the SEC, the Company will thereafter promptly cause the
Proxy Statement to be mailed to its stockholders. In connection therewith,
InfoCure Corporation, Parent, Merger Sub and the Company will prepare and file
any other filings required under the Exchange Act, the Securities Act or any
other Federal or blue sky laws relating to the Merger and the transactions
contemplated by this Agreement (the "Other Filings"). Each party will notify the
other party promptly upon the receipt of any comments from the SEC or its staff
and of any supplements to the Registration Statement, the Proxy Statement or any
Other Filing or for additional information and will supply the other party with
copies of all correspondence between such party or any of its representatives,
on the one hand, and the SEC, or its staff or other government officials, on the
other hand, with respect to the Registration Statement, the Proxy Statement, the
Merger or any Other Filing. The Proxy Statement, the Registration Statement and
the Other Filings will comply in all material respects with all applicable
requirements of law and the rules and regulations promulgated thereunder. Each
party agrees to cooperate with the other to provide all materials, documents,
exhibits and other requested information necessary to assure such compliance.
Whenever any event occurs which is required to be set forth in an amendment or
supplement to the Proxy Statement, the Registration Statement or any Other
Filing, InfoCure Corporation, Parent or the Company, as the case may be, will
promptly inform the other party of such occurrence and cooperate in filing with
the SEC or its staff or any other government officials, and/or mailing to
stockholders of the Company, such amendment or supplement. The Proxy Statement
will also include the approval of this Agreement and the Merger and the

<PAGE>

recommendation of the Board of Directors of the Company to Company's
shareholders that they vote in favor of approval of this Agreement and the
Merger, subject to the right of the Board of Directors of the Company to
withdraw its recommendation and recommend a Superior Proposal determined to be
such in compliance with Section 5.1. of this Agreement; provided, however, that
the Board of Directors of Company shall submit this Agreement to Company's
shareholders whether or not at any time subsequent to the date hereof such board
determines that it can no longer make such recommendation. Promptly after the
date hereof, the Company will exercise its best efforts and take all action
necessary in accordance with Colorado law and its Articles of Incorporation and
Bylaws to convene the Meeting to be held as promptly as practicable, and in any
event within (forty (40)) days after the declaration of effectiveness of the
Registration Statement, for the purpose of voting upon this Agreement. Unless
Company's Board of Directors has withdrawn its recommendation of this Agreement
and the Merger in compliance with Section 5.1., Company shall use all reasonable
efforts to solicit from its shareholders proxies in favor of the approval of
this Agreement and the Merger pursuant to the Proxy Statement and shall take all
other action necessary or advisable to secure the vote or consent of
shareholders required by Colorado Law or applicable stock exchange requirements
to obtain such approval. Notwithstanding any provision in this Agreement to the
contrary, the Company acknowledges and agrees that InfoCure Corporation and/or
Parent may, by notice to the Company, postpone the filing of the Registration
Statement, the request to accelerate the declaration of effectiveness of the
Registration Statement, or the mailing of the Proxy Statement to the Company's
shareholders if at any time the Board of Directors of InfoCure Corporation or
Parent, in good faith, determines that it would be detrimental to InfoCure
Corporation, the Parent or Company for such Registration Statement to be filed
or declared effective, or for such Proxy Statement to be mailed to the
shareholders of the Company; provided, that any such postponement shall not
exceed ninety (90) days in duration."

12.  Post Spin-off Stock Options and Warrants. Effective on the Spin-off Date,
     Section 6.4.A. of the Merger Agreement shall be and hereby is amended to
     read in its entirety as follows:

     "A. At the Effective Time, the Company's obligations with respect to each
outstanding Option or Warrant, whether vested or unvested, will be terminated
and such Option or Warrant shall be replaced with an option or warrant, as the
case may be, (such replacement options or warrants shall hereinafter be referred
to collectively as "Parent Securities" or individually as "Parent Security") to
acquire shares of Parent Common Stock equal to the product of the number of
shares of Company Common Stock that were purchasable under such Option or
Warrant immediately prior to the Effective Time multiplied by .0380324, rounded
up to the nearest whole number of shares of Parent Common Stock. The per share
exercise price for the shares of Parent Common Stock issuable upon exercise of
such Parent Security will be equal to the quotient determined by dividing the
exercise price per share of Company Common Stock at which the related Option or
Warrant was exercisable immediately prior to the Effective Time by .0380324 and
rounding the resulting exercise price up to the nearest whole cent. Each Parent
Security shall be evidenced by an option or warrant agreement in a form
acceptable to Parent and shall contain the following additional provisions: (i)
with respect to any Parent Security to be issued to Messrs. Horsley, Bayne and
Bilanich or to individuals who are former employees or directors of either

<PAGE>

Company or Subsidiary as of the date of this Agreement, the expiration date of
such Parent Security shall be the same expiration date as presently provided in
such party's existing option or warrant agreement with the Company and (ii) with
respect to any Parent Security to be issued to any other party not described in
clause (i) above, the expiration date of such Parent Security shall be the later
of (x) one (1) year from the date of Closing or (y) the thirtieth (30th) day
following termination of such employee's employment with the Company or
Subsidiary, but in no event shall such expiration date extend beyond the
expiration date presently provided in such party's existing option or warrant
agreement with the Company."

13.  Counterparts. This Second Amendment to the Merger Agreement may be executed
     in one or more counterparts, each of which shall be deemed to be an
     original copy of this Agreement, and all of which, when taken together,
     shall be deemed to constitute, but one and the same agreement.

14.  No Other Modifications. The Merger Agreement remains in full force and
     effect except as specifically modified hereby.

15.  Approvals and Recommendations. The Boards of Directors of Company and
     Parent have approved and declared advisable this Amendment, and have
     approved the Merger and the other transactions contemplated by this
     Agreement and have determined to recommend that the shareholders of Company
     adopt and approve (i) the Merger Agreement; (ii) this Amendment to the
     Merger Agreement and (iii) the Merger transaction.
