Revenue Code of 1986, as amended (the "Code"), by reason of section 368(a)(2)(D)
thereof.

         D. The parties intend that the Merger be accounted for as a pooling of
interests for financial reporting purposes.

efforts to take all action and to do all things necessary, proper or advisable
to consummate the Merger and the transactions contemplated by this Agreement
(including, without limitation, using its reasonable efforts to cause the
conditions set forth in this Section 5. for which they are responsible to be
satisfied as soon as reasonably practicable and to prepare, execute and deliver
such further instruments and take or cause to be taken such other and further
action as any other party hereto shall reasonably request).

                  B. Governmental Matters. Each of the parties shall use its
reasonable efforts to take any action that may be necessary, proper or advisable
in connection with any other notices to, filings with, and authorizations,
consents and approvals of any Governmental Body or other third party that it may
be required to give, make or obtain in connection with the Merger.

                  C. Pooling of interests. Each of the parties shall use its

treatment for financial reporting purposes. Neither the Company nor any
Shareholder or affiliate of the Company shall knowingly

                                       32
<PAGE>   38
take any action that would jeopardize the treatment of the Merger as a "pooling
of interests" for accounting purposes.

                  D. Tax-Deferred Treatment. Each of the parties shall use its
reasonable efforts to cause the Merger to constitute a tax-deferred
"reorganization" under section 368(a) of the Code.

                  E. Expenses. Except as expressly otherwise provided herein,
ISI and InfoCure on the one hand, and the Company on the other hand (but only up
through the Effective Time), shall bear its respective expenses incurred in
connection with the preparation, execution and performance of this Agreement and
the transactions contemplated hereby, including all fees and expenses of agents,
representatives, counsel and accountants. After the Effective Time, the
Shareholders shall be solely responsible for such fees and expenses relating to
themselves or the Company. In the case of termination of this Agreement, the
obligation of each party to pay its own expenses shall be subject to any rights
of such party arising from a breach of this Agreement by the other party.

                  F. Public Announcements. Unless otherwise required by
applicable laws, at all times prior to the earlier of the Effective Time or
termination of this Agreement pursuant to Section 8.1., the Company and InfoCure
shall consult with each other before issuing any press release with respect to
the Merger and shall not issue any such press release prior to such
consultation.

                  G. Access. From and after the date of this Agreement until the
Effective Time (or the termination of this Agreement), the Company, on the one
hand, and ISI and InfoCure, on the other hand, shall permit Representatives of
the other to have appropriate access at all reasonable times to the other's
premises, properties, books, records, contracts, tax records, documents,
customers and suppliers, and any information obtained by any party pursuant to
this Section 5.1.G. shall be subject to the provisions of the mutual
confidentiality agreement between them dated July 9, 1998, and the
confidentiality provisions of that certain Letter of Intent between the parties
dated January 7, 1999, which agreements remain in full force and effect.

                  H. Filing of 1998 and 1999 Short Period Income Tax Returns of
Company. Messrs. Davis and Simmons shall have prepared and shall file or cause
to be filed, at the expense of the Company, with the appropriate federal, state
and local government agencies (hereinafter, "Taxing Authorities"), within the
time prescribed by law, all required federal, state and local income tax returns
of the Company for calendar year 1998 and for the income tax period from January
1, 1999, to immediately prior to the Effective Date (the "Final Returns"), and
Shareholders shall be jointly and severally obligated to pay and shall pay,
prior to delinquency, all taxes due with respect to the Final Returns, which
shall include, without limitation, all taxes arising from all operations and
activities of the Company prior to the Effective Date. Prior to the filing of
the Final Returns, Simmons shall be appointed an officer of ISI and/or InfoCure,
in addition to any other officer position Simmons may hold pursuant to his
Employment Agreement, ("Tax Officer") for the sole purpose of causing to be
prepared and signing and filing the Final Returns, and Simmons shall have no
authority of any other kind or nature whatsoever and no ability to bind ISI
and/or InfoCure to any obligation or commitment whatsoever as Tax

                                       33
<PAGE>   39
Officer. The Final Returns shall be signed by Simmons, in his capacity as Tax
Officer, and by the certified public accounting firm (anticipated to be Babush
Neiman Kornman & Johnson, LLP) which prepares the Final Returns; and immediately
after the Final Returns are signed by Simmons, his position as Tax Officer shall
automatically terminate. At least ten (10) business days prior to the date the
Final Returns are filed, Simmons shall deliver copies of the proposed Final
Returns to ISI and InfoCure for their review and comment. If any Taxing
Authority, such as, but not limited to, the Internal Revenue Service or the
Georgia Department of Revenue, issues a notice of deficiency to ISI and/or
InfoCure with respect to the Final Returns, ISI shall be the party entitled to
contest any such deficiency notice; provided, however, that if the Shareholders,
or any of the Shareholders, would be obligated to pay such taxes, or to
indemnify ISI and/or InfoCure, for, any tax deficiency or liability related
thereto, then (i) the Shareholders, as a group, hereby appoint Messrs. Simmons
and Davis as their representatives, together with an attorney or accountant of
Messrs. Simmons and Davis (whose fees and expenses shall be borne by
Shareholders), to participate in the contesting of such deficiency and (ii)
neither ISI or InfoCure shall settle or compromise the liability with respect
thereto without the prior written consent of Messrs. Simmons and Davis, which
consent shall not be unreasonably withheld; provided, that Messrs. Simmons and
Davis shall be entitled to consent to any such settlement or compromise on
behalf of all of the Shareholders. In the event ISI or InfoCure requests, in
writing, a consent of Messrs. Simmons and Davis for any such settlement or
compromise and Messrs. Simmons and Davis fail to respond to such request within
twenty (20) days of the delivery thereof, then such failure to respond shall
constitute consent to such settlement or compromise that shall be binding on the
Shareholders.

                  I. Filing of Amended Income Tax Returns of Company. At any
time after the Effective Date, Messrs. Davis and Simmons shall have the
authority to have prepared and file or cause to be filed, at the expense of
Messrs. Davis and Simmons, with the appropriate federal, state and local
government agencies (hereinafter, "Taxing Authorities"), within the time
prescribed by law, any appropriate or required federal, state and local income
tax returns of the Company for any periods ending prior to the Effective Date
(the "Amended Returns"), and Shareholders shall be (i) jointly and severally
obligated to pay and shall pay any taxes due with respect to the Amended
Returns, which shall include, without limitation, all taxes arising from all
operations and activities of the Company prior to the Effective Date and (ii)
entitled to receive any income tax refunds generated as a result of any such
Amended Returns. ISI and/or InfoCure hereby irrevocably appoint Simmons an
officer of ISI and/or InfoCure, in addition to any other officer position
Simmons may hold pursuant to his Employment Agreement, ("Tax Officer") for the
sole purpose of causing to be prepared and signing and filing the Amended
Returns, and Simmons shall have no authority of any other kind or nature
whatsoever and no ability to bind ISI and/or InfoCure to any obligation or
commitment whatsoever as Tax Officer. The Amended Returns shall be signed by
Simmons, in his capacity as Tax Officer, and by the certified public accounting
firm (anticipated to be Babush Neiman Kornman & Johnson, LLP) which prepares the
Amended Returns. Immediately after the Amended Returns are filed, Simmons shall
deliver copies of the Amended Returns to ISI and InfoCure. If any Taxing
Authority, such as, but not limited to, the Internal Revenue Service or the
Georgia Department of Revenue, issues a notice of deficiency to ISI and/or
InfoCure with respect to the Amended Returns, ISI shall be the party entitled to
contest any such deficiency notice; provided, however, that if the Shareholders,
or any

                                       34
<PAGE>   40
of the Shareholders, would be obligated to pay such taxes, or to indemnify ISI
and/or InfoCure, for, any tax deficiency or liability related thereto, then (i)
the Shareholders, as a group, hereby appoint Messrs. Simmons and Davis as their
representatives, together with an attorney or accountant of Messrs. Simmons and
Davis (whose fees and expenses shall be borne by Shareholders), to participate
in the contesting of such deficiency and (ii) neither ISI or InfoCure shall
settle or compromise the liability with respect thereto without the prior
written consent of Messrs. Simmons and Davis, which consent shall not be
unreasonably withheld; provided, that Messrs. Simmons and Davis shall be
entitled to consent to any such settlement or compromise on behalf of all of the
Shareholders. In the event ISI or InfoCure requests, in writing, a consent of
Messrs. Simmons and Davis for any such settlement or compromise and Messrs.
Simmons and Davis fail to respond to such request within twenty (20) days of the
delivery thereof, then such failure to respond shall constitute consent to such
settlement or compromise that shall be binding on the Shareholders.

         7.1. Agreement by Shareholders to Indemnify. Subject to the limitations
set forth in Section 7.1.1 and in Section 7.1.2, the Shareholders, severally and
not jointly, in proportion to each Shareholder's relative Percentage Ownership,
agree that they will indemnify and hold ISI


                                       39
<PAGE>   45
and InfoCure harmless in respect of the aggregate of all indemnifiable Damages
of ISI and InfoCure.

         For this purpose, "indemnifiable Damages" of ISI or InfoCure means the
aggregate of all Damages incurred or suffered by ISI and InfoCure resulting
from:

                  A. Any inaccurate representation or warranty made by the
Company or the Shareholders in or pursuant to this Agreement; or

                  B. Any breach of or default in the performance of any of the
covenants or agreements made by the Company or the Shareholders in this
Agreement.

         The foregoing obligation of the Shareholders to indemnify InfoCure and
ISI shall be subject to each of the following principles or qualifications:

                  7.1.1 All representations, warranties and covenants of the
Company, the Shareholders, ISI and InfoCure contained in this Agreement will
remain operative and in full force and effect for a period ending on the earlier
of (i) one (1) year after the Closing and (ii) publication of audited combined
financial statements of InfoCure and the Company for the fiscal year ended
December 31, 1999.

                  7.1.2 In seeking indemnification for any indemnifiable Damages
otherwise payable to ISI or InfoCure under this Agreement following the Closing,
ISI and InfoCure, as the case may be, shall exercise its remedies only with
respect to those certain escrow shares deposited in escrow pursuant to the
Escrow Agreement. Notwithstanding the foregoing, the Shareholders shall be
responsible for indemnifiable Damages only to the extent that the aggregate
amount of such indemnifiable Damages exceeds Three Hundred Thousand and No/100
Dollars ($300,000.00) and then only for the amount of such excess up to the
amount of the escrow shares deposited in escrow pursuant to the Escrow
Agreement.

         7.2. Matters Involving Third Parties. If any third party shall notify
ISI or InfoCure (the "Indemnified Party") with respect to any matter which may
give rise to a claim by ISI or InfoCure for indemnification against the
Shareholders (collectively the "Indemnifying Party") under this Section 7. (a
"Third Party Claim") then the Indemnified Party shall notify the Indemnifying
Party promptly; provided, however, that no delay on the part of the Indemnified
Party in notifying any Indemnifying Party shall relieve the Indemnifying Party
from any liability or obligation hereunder unless (and then solely to the extent
that) the Indemnifying Party thereby is Damaged.

         If the Indemnifying Party notifies the Indemnified Party within fifteen
(15) days after the Indemnified Party has given notice of the matter that the
Indemnifying Party is assuming the defense thereof, then:

                  A. The Indemnifying Party will defend the Indemnified Party
against the matter with counsel of its choice reasonably satisfactory to the
Indemnified Party;


                                       40
<PAGE>   46
                  B. The Indemnified Party may retain separate co-counsel at its
sole cost and expense (except that the Indemnifying Party will be responsible
for the fees and expenses of the separate co-counsel to the extent the
Indemnified Party concludes that the counsel the Indemnifying Party has selected
has a conflict of interest);

                  C. The Indemnifying Party will not consent to the entry of any
judgment or enter into any settlement with respect to the matter without the
written consent of the Indemnified Party (not to be withheld or delayed
unreasonably); and

                  D. The Indemnifying Party will not consent to the entry of any
judgment with respect to the matter, or enter into any settlement which does not
include a provision whereby the plaintiff or claimant in the matter releases the
Indemnified Party from all liability with respect thereto, without the written
consent of the Indemnified Party (not to be withheld or delayed unreasonably).

         If (i) the Indemnifying Party fails to notify the Indemnified Party
within fifteen (15) days after the Indemnified Party has given notice of the
matter that the Indemnifying Party is assuming the defense thereof or (ii) the
Indemnifying Party notifies the Indemnified Party within fifteen (15) days after
the Indemnified Party has given notice of the matter that the Indemnifying Party
is not assuming the defense thereof, then the Indemnified Party may defend
against, or enter into any settlement with respect to, the matter in any manner
it may deem appropriate.

         7.3. Appointment of Shareholders' Representative. Each Shareholder
constitutes and appoints Reid W. Simmons and James C. Davis, D.M.D.
(collectively the "Shareholders' Representative") as his true and lawful
attorney-in-fact to act for and on behalf of such Shareholders in all matters
relating to or arising out of this Section 7. and the liability or asserted
liability of such Shareholder, hereunder, including specifically, but without
limitation, accepting and agreeing to the liability of such Shareholder with
respect to any indemnification claim, objecting to any indemnification claim,
disputing the liability of such Shareholder, or the amount of such liability,
with respect to any indemnification claim and prosecuting and resolving such
dispute as herein provided, accepting the defense, compromise and settlement of
any Third Party Claim on behalf of such Shareholder or refusing to accept the
same, settling and compromising the liability of such Shareholder hereunder,
instituting and prosecuting such actions (including arbitration proceedings) as
the Shareholders' Representative shall deem appropriate in connection with any
of the foregoing, retaining counsel, accountants, appraisers and other advisers
in connection with any of the foregoing, all for the account of the Shareholder,
such Shareholder agreeing to be fully bound by the acts, decisions and
agreements of the Shareholder Representative taken and done pursuant to the
authority herein granted. Each Shareholder hereby agrees to indemnify and to
save and hold harmless the Shareholders' Representative from any liability
incurred by the Shareholders' Representative based upon or arising out of any
act, whether of omission or commission, of the Shareholders' Representative
pursuant to authority herein granted, other than acts, whether of omission or
commission, of the Shareholders' Representative that constitute willful
misconduct in the exercise by the Shareholders' Representative of the authority
herein granted. The death or incapacity of any Shareholder shall not terminate
the authority and agency of the Shareholders' Representative. In the event of
the resignation of either Reid W. Simmons or James C. Davis, D.M.D., the other
party shall continue

as Shareholders' Representative hereunder and in the event of the resignation of
such other party, the resigning Shareholders' Representative shall appoint a
successor either from among the Shareholders or who shall otherwise be
acceptable to ISI and InfoCure and who shall agree in writing to accept such
appointment, and the resigning Shareholders' Representative's resignation shall
not be effective until such a successor shall exist. If the Shareholders'
Representative is a natural person and if such Shareholders' Representative
should die or become incapacitated, then his successor shall be appointed within
thirty (30) days of his death or incapacity by a majority of the Shareholders
and such successor either shall be a Shareholder or shall otherwise be
acceptable to InfoCure. The choice of a successor Shareholders' Representative
appointed in any manner permitted above shall be final and binding upon all of
the Shareholders. The decisions and actions of any successor Shareholders'
Representative shall be, for all purposes, those of a Shareholders'
Representative as if originally named herein.

and such breach cannot be cured prior to the Closing Date and has not been

with its obligations hereunder, and such conditions shall not have been waived
by the ISI and InfoCure on or before such date; or

                           (ii) By the Company and the Shareholders if all of

Shareholders to fully materially comply with its obligations hereunder, and such
conditions shall not have been waived by the Company on or before such date;

                  C. By the Shareholders if the Average Per Share Closing Price
is less than Twenty-Four and No/100 Dollars ($24.00) and the Shareholders have
provided notice to ISI and InfoCure of their intention to terminate this
Agreement pursuant to this provision, unless InfoCure and ISI provide notice to
the Shareholders within twenty-four (24) hours of receipt of the Shareholders'
notice hereunder of InfoCure's agreement to increase the Exchange Ratio to an
amount equal (i) the product of (1) the quotient determined by dividing
Twenty-Four and No/100 Dollars ($24.00) by the Average Per Share Closing Price,
multiplied by (2) 1,144,000, divided by (ii) ten thousand (10,000) shares;

                  D. By mutual consent of the Company, ISI and InfoCure; or

<PAGE>   48
                  E. By either the Company and the Shareholders or ISI and
InfoCure if the Closing shall not have occurred, other than through failure of
any such party to materially fulfill its obligations hereunder, on or before
March 15, 1999, or such later date as may be agreed upon by the parties.

         Each party's right of termination hereunder is in addition to any other
rights it may have hereunder or otherwise and the exercise of a right of
termination shall not be an election of remedies.

are cumulative and not alternative. Neither the failure nor any delay on the
part of any party in exercising any right, power or privilege under this
Agreement or the documents referred to herein shall operate as a waiver thereof,

preclude any other or further exercise thereof or the exercise of any other
right, power or privilege. To the maximum extent permitted by applicable law, no
claim or right arising out of this Agreement or the documents referred to herein
can be discharged by one party hereto, in whole or in part, by a waiver or
renunciation of the claim or right unless in writing signed by the other party
hereto; no waiver which may be given by a party hereto shall be applicable
except in the specific instance for which it is given; and no notice to or
demand on one party hereto shall be deemed to be a waiver of any obligation of
such party or of the right of the party giving such notice or demand to take
further action without notice or demand as provided in this Agreement or the
documents referred to herein.

         9.4. Entire Agreement and Modification. This Agreement, including all
exhibits and schedules hereto, are intended by the parties to this Agreement as

conditions of that agreement. This Agreement may not be modified, rescinded or
terminated orally, and no modification, rescission, termination or attempted
waiver of any of the provisions hereof (including this Section) shall be valid
unless in writing and signed by the party against whom the same is sought to be
enforced.

         9.5. Assignments, Successors and No Third-Party Rights. This Agreement
shall apply to and be binding in all respect upon, and shall inure to the
benefit of, the successors and assigns of the parties hereto. Nothing expressed
or referred to in this Agreement is intended or shall be construed to give any
person or entity other than the parties to this Agreement any legal or equitable
right, remedy or claim under or with respect to this Agreement, or any provision
hereof, it being the intention of the parties hereto that this Agreement and all
of its provisions and conditions are for the sole and exclusive benefit of the
parties to this Agreement, their successors and assigns, and for the benefit of
no other person or entity; provided, however, that the parties hereto consent to
the assignment of interests in this Agreement, including all exhibits and
schedules hereto, as collateral security for the obligations of InfoCure and ISI
following the Closing to FINOVA Capital Corporation.

         9.6. Pooling of Interests. If any provision of this Agreement or the
application of any such provision to any person or circumstance precludes the
use of "pooling of interests" accounting treatment in connection with the
transactions contemplated by this Agreement, then such provision shall be of no
force and effect to the extent, and solely to the extent necessary to preserve
such accounting treatment and in the event, the remainder of this Agreement
shall not be affected, and in lieu of such provision there shall be added as
part of this Agreement a provision as similar in terms as may be possible for
the transactions contemplated by this Agreement to be treated as a "pooling of
interests" for accounting purposes.

         9.7. Section Headings, Construction. The headings of articles and
sections contained in this Agreement are provided for convenience only. They
form no part of this Agreement and shall not affect its construction or

import, refer to this Agreement as a whole and not to any particular section,
subsection, paragraph, clause or other subdivision hereof.

         9.8. Time of Essence. With regard to all time periods set forth or
referred to in this Agreement, time is of the essence.

         9.9. Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED
UNDER, THE LAWS OF THE STATE OF GEORGIA WITHOUT REGARD TO CONFLICTS OF LAWS, ALL
RIGHTS AND REMEDIES BEING GOVERNED BY SUCH LAWS.

         9.10. Counterparts. This 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.

         9.11. Reservation of Rights With Respect to Gwaltney Dispute. The
parties hereto acknowledge that a bona fide dispute exists related to the
interpretation and enforceability of Option Agreement by and between Gwaltney
and Davis and Simmons dated March 30, 1990, as amended (hereinafter the
"Gwaltney Option Agreement"). The parties acknowledge that Davis and Simmons
have maintained the position that Gwaltney has by his conduct waived his rights
to acquire OMS Common stock pursuant to the Gwaltney Option Agreement. The
parties further acknowledge that Gwaltney has maintained the position that
Gwaltney has not by his conduct waived any rights to acquire OMS Common Stock
pursuant to the Gwaltney Option Agreement. It is the mutual desire of all
parties that they be permitted to execute the Agreement and the Ancillary
Agreements without in any way prejudicing their respective positions regarding
the aforementioned dispute concerning the Gwaltney Option Agreement. Therefore
the parties hereto each specifically reserve any right to pursue any claim
concerning the Gwaltney Option Agreement. The parties acknowledge that the
Agreement and the Ancillary Agreements shall not be deemed an admission against
the interests of any party regarding the Gwaltney Option Agreement. Without
limiting the generality of the foregoing, by the execution of the Agreement and
the Ancillary Agreement and the issuance and exchange of any stock by any of the
parties hereto:

Common stock pursuant to the Gwaltney Option Agreement.

                  B. Davis and Simmons acknowledge and agree that Gwaltney is
not admitting that Gwaltney has waived any rights that he has in connection with
