         A.       InfoCure is the common parent of an affiliated group of
corporations within the meaning of Section 1504(a) of the Internal Revenue Code
of 1986, as amended (the "Code"), which currently files consolidated federal
income tax returns.

         B.       Pursuant to the Agreement and Plan of Distribution dated
_________, 2001 by and between InfoCure and PracticeWorks (the "Distribution
Agreement"), the following transactions will occur: (i) InfoCure Systems, Inc.,
a Georgia corporation ("ISI"), will elect to become a Georgia limited liability
company ("ISI, LLC") pursuant to Section 14-2-1109.1 of the Georgia Business
Corporation Code (the "ISI Conversion"); (ii) InfoCure (directly and through
ISI, LLC) will contribute certain assets and liabilities to PracticeWorks in
exchange for shares of PracticeWorks common stock (the "Contribution
Transaction"), and then (iii) InfoCure will distribute all of the outstanding
shares of the common stock of PracticeWorks pro rata to the holders of InfoCure
common stock (the "Distribution").

         C.       InfoCure and PracticeWorks intend that the ISI Conversion will
qualify as a transaction described in Sections 332 and 337 of the Code, that the
Contribution Transaction and the Distribution will qualify as a reorganization
described in Section 368(a)(1)(D) of the Code, that the Distribution will
qualify as a distribution described in Section 355 of the Code and that none of
such transactions will result in the recognition of any taxable gain or income
to InfoCure, ISI, PracticeWorks or any shareholder of InfoCure or PracticeWorks
(except to the extent of cash received for any fractional share interest in
PracticeWorks stock and any deferred intercompany gain).

         D.       From and after Date of the Distribution, PracticeWorks will
cease to be a member of the InfoCure affiliated group for federal income tax
purposes.

for nonrecognition of gain by the InfoCure Group, including, without limitation,
by reason of (x) any stock or securities of PracticeWorks failing to qualify as
"qualified property" within the meaning of Sections 355(c)(2) or 361(c)(2) of
the Code or (y) the application of Section 355(e) of the Code to the

an InfoCure Tainting Act or a PracticeWorks Tainting Act), the liability of
InfoCure and PracticeWorks for any Taxes arising from such Final Determination
and any liability to shareholders arising from such Final Determination
(together with any reasonable expense (including, but not limited to, attorney's
fees) incurred in defending against any liability) shall be borne 50 percent by
InfoCure and 50 percent by PracticeWorks. If an InfoCure Tainting Act and a
PracticeWorks Tainting Act both contribute to such a Final Determination, any
such Taxes or liability (together with any reasonable expense (including, but
not limited to, attorney's fees) incurred in defending against any liability)
shall be borne 50 percent by InfoCure and 50 percent by PracticeWorks.

                  (b)      INDEMNIFICATION FOR PRACTICEWORKS TAINTING ACTS.
PracticeWorks covenants that neither PracticeWorks nor any member of the
PracticeWorks Group shall commit or be party to or the subject of any
PracticeWorks Tainting Act which would result in any Tax or liability described
in the following sentence and payable by InfoCure. To the extent that any member
of the InfoCure Group would not have been liable for the following amounts but
for a PracticeWorks Tainting Act, PracticeWorks shall pay, and shall indemnify
and hold harmless the InfoCure Group from and against, (i) any liability of any
member of the InfoCure Group to any Taxing Authority, InfoCure shareholders or
PracticeWorks shareholders (together with any reasonable expenses (including,
but not limited to, attorney's fees) incurred in defending against any such
liability) resulting from a Final Determination that the ISI Conversion failed
to qualify for nonrecognition treatment or that the Distribution failed to meet
the requirements of Sections 355 or 361 of the Code for nonrecognition of gain
by the InfoCure Group, including, without limitation, by reason of (x) any stock
or securities of PracticeWorks failing to qualify as "qualified property" within

                  (c)      INDEMNIFICATION FOR INFOCURE TAINTING ACTS. InfoCure
covenants that neither InfoCure nor any member of the InfoCure Group shall
commit or be party to or the subject of any InfoCure Tainting Act which would
result in any Tax or liability described in the following sentence and payable
by PracticeWorks. To the extent that PracticeWorks would not have been liable
for the following amounts but for an InfoCure Tainting Act, InfoCure shall pay,
and shall indemnify and hold harmless PracticeWorks from and against, (i) any
liability of PracticeWorks to any Taxing Authority, InfoCure shareholders or
PracticeWorks shareholders (together with any reasonable expenses (including,
but not limited to, attorney's fees) incurred in defending against any such
liability) resulting from a Final Determination that the ISI Conversion failed
to qualify for nonrecognition treatment or that the Distribution failed to meet
the requirements of Sections 355 or 361 of the Code for nonrecognition of gain
by the InfoCure Group, including, without limitation, by reason of (x) any stock
or securities of PracticeWorks failing to qualify as "qualified property" within

application of Section 355(e) of the Code to the Distribution, and (ii) any
Taxes and related expenses payable by PracticeWorks by reason of the receipt of
such payment.

         2.05     PERIOD THAT INCLUDES THE DATE OF DISTRIBUTION. (a) To the
extent permitted by law or administrative practice, the taxable year of the
PracticeWorks Group shall be treated as closing at the close of the Date of
Distribution.

                  (b)      If it is necessary for purposes of this Agreement to
determine the Tax liability of any member of the PracticeWorks Group for a
taxable year or period that begins on or before and ends after the Date of the
Distribution and is not treated under Section 2.05(a) as closing at the close of
the Date of Distribution, the determination shall be made, in the case of Taxes
that are based upon income or receipts, by assuming that the relevant taxable
period ended at the close of the Date of Distribution, except that any
exemptions, allowances or deductions that are calculated on an annual basis
shall be apportioned on a time basis. In the case of Taxes that are imposed on a
periodic basis, are payable for a taxable period that includes (but does not end
on) the Date of Distribution, and are not based upon or related to income or
receipts, the portion of such Tax that relates to the Period Before Distribution
shall be deemed to be the amount of such Tax for the entire taxable period
multiplied by a fraction the numerator of which is the number of days in the
taxable period ending on the Date of Distribution and the denominator of which
is the number of days in the entire taxable period.

                                  ARTICLE III.

entitled to carry back any net operating loss or other item from a Period After
Distribution to a Period Before Distribution, except to the extent that InfoCure
determines in good faith that such action will cause an actual increase in the
Taxes for which the InfoCure Group is responsible or will cause an actual
reduction in the amount of any refund of Taxes payable to the InfoCure Group.



                                       8
<PAGE>   9

PracticeWorks Group shall be payable to PracticeWorks as provided in Section
2.03(a).

         3.02     DISTRIBUTIONS AND ELECTIONS. (a) No member of the
PracticeWorks Group shall make any election with respect to Taxes, pay or cause
to be paid any distribution from an Affiliate or take any other action that

responsible or will cause an actual reduction in the amount of any refund of
Taxes payable to the InfoCure Group.

                  (b)      No member of the InfoCure Group shall make any
election with respect to Taxes, pay or cause to be paid any distribution from an
Affiliate or take any other action that shall cause an actual increase in the
Taxes for which the PracticeWorks Group is responsible or will cause an actual
reduction in the amount of any refund of Taxes payable to the PracticeWorks

                                  ARTICLE IV.

information, FTC receipts and Section 861 information may be provided within one
hundred twenty (120) days from the Date of Distribution) of its Fiscal Year 2001
Stub Period operating and nonoperating tax and financial results; (ii)
PracticeWorks will calculate in accordance with the principles established in
Section 2.03 and submit to InfoCure an estimate of its Fiscal Year 2001 Stub
Period Tax liability, offsetting such liability by the amount, if any,
determined to be owed to PracticeWorks for Fiscal Year 2000 pursuant to Section
4.01(b), to the extent payment has not already been received by PracticeWorks
for such overpayment pursuant to Section 4.01(b); (iii) InfoCure shall have the

final amount owed, if any, under clause (ii) of this Section 4.01(a) shall be
made when the InfoCure Group's Fiscal Year 2001 Tax Returns are filed and shall
be paid within thirty (30) days from the date InfoCure notifies PracticeWorks of
any

additional amounts due together with interest at a rate equal to the Applicable
Federal Rate from the date on which such Tax Return is filed. Similarly, any
refund owed PracticeWorks over the amount previously determined and paid under
clause (ii) of this Section 4.01(a) shall be refunded by InfoCure within the
same thirty (30) day period together with interest at a rate equal to the
Applicable Federal Rate from the date on which InfoCure receives such refund,
and any claims resulting from carrybacks, tax audits or a Final Determination
shall be handled in the same manner as provided in Articles V, VI, VII, and
VIII.

                  (b)      PracticeWorks shall determine and pay the final
amount owed, if any, under clause (i)(B) of Section 2.03(a) for Fiscal Year 2000
as follows: (i) PracticeWorks shall provide InfoCure with a copy of its Federal
and State tax package, together with standard items such as Internal Revenue
Service Form 5471s, boycott information, FTC receipts and Section 861
information, in the normal InfoCure format and according to the normal InfoCure
schedule, of its Fiscal Year 2000 operating and nonoperating tax and financial
results; (ii) InfoCure shall prepare and file those Tax Returns in respect of
Fiscal Year 2000 that it is obligated to file pursuant to Section 2.01; (iii)
PracticeWorks shall prepare a reconciliation of the amounts PracticeWorks has
paid either directly or indirectly through inter-company charges in respect of
the InfoCure Fiscal Year 2000 consolidated federal Tax Return or any other Tax
Return in respect of Fiscal Year 2000 that InfoCure is required to file pursuant
to Section 2.01 to the calculation of the PracticeWorks Group's final liability
for Fiscal Year 2000 to be determined from such Tax Returns in accordance with
the principles established in Section 2.03(a), and shall provide such
reconciliation to InfoCure within thirty (30) days before the due date for
filing the relevant Tax Return; (iv) InfoCure shall have the right to object in
writing to such reconciliation in accordance with the principles established in
Section 4.01(a)(iii) within fifteen (15) days of delivery of the reconciliation;
(v) if the reconciliation described in clause (iii) of this Section 4.01(b)
indicates that PracticeWorks owes InfoCure money, PracticeWorks shall pay the
balance to InfoCure within thirty (30) days of the delivery of such
reconciliation together with interest at a rate equal to the Applicable Federal
Rate from the date on which such Tax Return was filed. If the reconciliation
shows that InfoCure owes PracticeWorks money and PracticeWorks' overpayment
cannot be applied to PracticeWorks' Fiscal Year 2001 Stub Period Tax liabilities
pursuant to Section 4.01(a)(ii), InfoCure shall pay such balance to
PracticeWorks within five (5) days of InfoCure's receipt of such balance from
the relevant Taxing Authority to the extent that a refund is due from the
relevant Taxing Authority (with no interest) and concurrently with delivery of
the reconciliation to the extent that no refund is due from the relevant Taxing
Authority (together with interest at a rate equal to the Applicable Federal Rate
from the due date of the Tax Return); and (vi) any claims resulting from
carrybacks, tax audits or Final Determination shall be handled in the same
manner as provided in Articles V, VI, VII and VIII.

         4.02     OTHER PAYMENTS. Other payments due to a party under Section
2.03 shall be due not later than twenty (20) days after the receipt or crediting
of a refund or the receipt of notice of a Final Determination that the
indemnified party is liable for an indemnified cost, together with interest at a
rate equal to the Applicable Federal Rate from the date on which the
indemnifying party receives such receipt, credit or notice.

         4.03     NOTICE. InfoCure and PracticeWorks shall give each other
prompt written notice of any payment that may be due under this Agreement.

                                   ARTICLE V.

                                   TAX AUDITS

         5.01     GENERAL. Except as provided in Sections 5.02 and 6.02, each of
PracticeWorks and InfoCure shall have sole responsibility for all audits or
other proceedings with respect to Tax Returns that it is required to file under
Section 2.01 (the "Controlling Party"). Except as provided in Section 5.03, the
Controlling Party shall have the sole right to contest the audit or proceeding
and to employ advisors of its choice.

         5.02     INDEMNIFIED CLAIMS IN GENERAL. InfoCure or PracticeWorks shall
promptly notify the other in writing prior to the issuance of an actual notice
of assessment by the relevant Taxing Authority (for example, if by the Internal
Revenue Service, prior to the issuance of a Form 5701 Notice of Proposed
Adjustment) of any proposed adjustment to a Tax Return that may result in
liability of the other party (the "Indemnitor") under this Agreement. If the
Indemnitor is not also the Controlling Party, the Controlling Party shall
provide the Indemnitor with information about the nature and amounts of the
proposed adjustments and shall permit the other party to participate in the
proceeding at its own expense, PROVIDED, HOWEVER, that the Controlling Party
shall not be required to indemnify the Indemnitor if the Controlling Party fails
to notify or provide such information to the Indemnitor, unless the Indemnitor
is materially prejudiced thereby. The Indemnitor shall pay all reasonable
expenses (including, but not limited to, legal and accounting fees) incurred by
the Controlling Party in connection with the assessment or adjustment within
seven (7) days after a written request by the Controlling Party.

         5.03     CERTAIN FEDERAL INCOME TAX CLAIMS. (a) Any issues raised by
the Internal Revenue Service ("IRS") in any tax inquiry, audit, examination,
investigation, dispute, litigation or other proceeding which would result in
federal income tax liability to the Indemnitor which in the aggregate would
equal or exceed $100,000 in any taxable year are defined as a Claim (a "Claim").
Except as provided in Section 5.03(d) and notwithstanding any other provision of
this Agreement that may be construed to the contrary, the Controlling Party
agrees to contest any Claim and not to settle any Claim without prior written
consent of the Indemnitor, PROVIDED that (i) the Controlling Party shall provide
notice to Indemnitor pursuant to Section 5.02 of any Claim, (ii) within thirty
(30) days after notice by the Controlling Party to the Indemnitor of a Claim is
received by the Indemnitor, the Indemnitor shall request in writing that such
Claim be contested, (iii) within thirty (30) days after notice by the
Controlling Party to the Indemnitor of such Claim is received by the Indemnitor,
the Indemnitor shall have provided an opinion of independent tax counsel,
selected by the Indemnitor and reasonably acceptable to the Controlling Party,
to the effect that it is more likely than not that a Final Determination will be
substantially consistent with the Indemnitor's position relating to such Claim,
(iv) the Indemnitor agrees to pay on demand and pays all out-of-pocket costs,
losses and expenses (including, but not limited to, legal and accounting fees)
paid or incurred by the Controlling Party in connection



                                       11
<PAGE>   12


with contesting such Claim, except for a Claim where the expenses are shared
pursuant to Section 2.04(a), and (v) the Controlling Party, after reasonable
consultation with the Indemnitor, shall determine in its sole discretion the
nature of all actions to be taken to contest such Claim, including (1) whether
any action to contest such Claim shall initially be by way of judicial or
administrative proceeding, or both, (2) whether any such Claim shall be
contested by resisting payment thereof or by paying the same and seeking a
refund thereof, and (3) the court or other judicial body before which judicial
action, if any, shall be commenced. To the extent the Indemnitor is not
participating, the Controlling Party shall keep the Indemnitor and, upon request
by the Indemnitor, its counsel informed as to the progress of the contest.

                  (b)      If the Indemnitor requests that the Controlling Party
accept a settlement of a Claim offered by the IRS and if such Claim may, in the
reasonable discretion of the Controlling Party, be settled without prejudicing
any claims the IRS may have with respect to matters other than the transactions
contemplated by the Distribution Agreement, the Controlling Party shall either
accept such settlement offer or agree with the Indemnitor that the Indemnitor's
liability with respect to such Claim shall be limited to the lesser of (i) an
amount calculated on the basis of such settlement offer plus interest owed to
the IRS on the date of eventual payment or (ii) the amount calculated on the
basis of a Final Determination.

                  (c)      If the Controlling Party shall elect to pay the Tax
claimed and seek a refund, the Indemnitor shall lend sufficient funds on an
interest-free basis to the Controlling Party, and with no net after-tax cost to
the Controlling Party, to cover any applicable indemnity obligations of the
Indemnitor. To the extent such refund claim is ultimately disallowed, the loan
or portion thereof equal to the amount of the refund claim so disallowed shall
be applied against the Indemnitor's obligation to make indemnity payments
pursuant to this Agreement. To the extent such refund claim is allowed, the
Controlling Party shall pay to the Indemnitor all amounts advanced to the
Controlling Party with respect to the indemnity obligation within ten (10) days
of the receipt of such refund (or if the Controlling Party would have received
such refund but for the existence of a counterclaim or other claim not
indemnified by the Indemnitor under this Agreement, within ten (10) days of the
final resolution of the contest), plus an amount equal to any interest received
(or that would have been received) from the IRS that is properly attributable to
such amount.

                  (d)      Except as provided below, the Controlling Party shall
not settle a Claim that Indemnitor is entitled to require the Controlling Party
to contest under Section 5.03(a) without the prior written consent of the
Indemnitor. At any time, whether before or after commencing to take any action
pursuant to this Section 5.03 with respect to any Claim, the Controlling Party
may decline to take action with respect to such Claim and may settle such Claim
without the prior written consent of the Indemnitor by notifying the Indemnitor
in writing that the Indemnitor is released from its obligations to indemnify the
Controlling Party with respect to such Claim (which notification shall release
the Indemnitor from such obligations except to the extent the Indemnitor has
agreed in writing that it would be willing to have its liability calculated on
the basis of a settlement offer, as provided in Section 5.03(b), at that point
in the contest) and with respect to any Claim related to such Claim or based on
the outcome of such Claim. If the



                                       12
<PAGE>   13


Controlling Party settles any Claim or otherwise takes or declines to take any
action pursuant to this paragraph, the Controlling Party shall pay to the
Indemnitor any amounts paid or advanced by the Indemnitor with respect to such
Claim (other than amounts payable by the Indemnitor in connection with a
settlement offer pursuant to Section 5.03(b)), plus interest attributable to
such amounts.

                                  ARTICLE VI.

                                   COOPERATION

         6.01     GENERAL. InfoCure and PracticeWorks shall cooperate with each
other in the filing of any Tax Returns and the conduct of any audit or other
proceeding and each shall execute and deliver such powers of attorney and make
available such other documents as are reasonably necessary to carry out the
intent of this Agreement. Each party agrees to notify the other party in writing
of any audit adjustments which do not result in Tax liability but can be
reasonably expected to affect Tax Returns of the other party, or any of its
Subsidiaries, for a Period After Distribution. Each party agrees to treat the
Distribution for all income tax purposes as not causing the recognition of any
gain or loss.

         6.02     COOPERATION WITH RESPECT TO TAX RETURN FILINGS, EXAMINATIONS
AND TAX RELATED CONTROVERSIES.

                  (a)      INFOCURE'S OBLIGATIONS. In addition to any
obligations imposed pursuant to the Distribution Agreement, InfoCure and each
other member of the InfoCure Group shall fully cooperate with PracticeWorks and
its representatives, in a prompt and timely manner, in connection with (i) the
preparation and filing of and (ii) any inquiry, audit, examination,
investigation, dispute, or litigation involving, any Tax Return filed or
required to be filed by or for any member of the PracticeWorks Group for any
taxable period beginning on or before the Distribution Date. Such cooperation
shall include, but not be limited to, (x) the execution and delivery to
PracticeWorks by the appropriate InfoCure Group member of any power of attorney
required to allow PracticeWorks and its counsel to represent InfoCure or such
other InfoCure Group member in any controversy which PracticeWorks shall have
the right to control pursuant to the terms of Section 5.01 of this Agreement,
(y) making available to PracticeWorks, during normal business hours, and within
sixty (60) days of any written request therefor, all books, records and
information, and the assistance of all officers and employees, necessary or
useful in connection with any tax inquiry, audit, examination, investigation,
dispute, litigation or any other matter, and (z) use of its best efforts in
defending PracticeWorks' interests in any tax inquiry, audit, examination,
investigation, dispute, litigation or any other matter for which InfoCure is the
Controlling Party.

                  (b)      PRACTICEWORKS' OBLIGATIONS. Except as otherwise
provided in this Article VI, PracticeWorks shall fully cooperate with InfoCure
and its representatives, in a prompt and timely manner, in connection with (i)
the preparation and filing of and (ii) any inquiry, audit, examination,
investigation, dispute, or litigation involving, any Tax Return filed or
required to be filed by or for any member of the InfoCure Group which includes



                                       13
<PAGE>   14


PracticeWorks or any other member of the PracticeWorks Group. Such cooperation
shall include, but not be limited to, (x) the execution and delivery to InfoCure
by PracticeWorks of any power of attorney required to allow InfoCure and its
counsel to participate on behalf of InfoCure or other InfoCure Group members in
any inquiry, audit or other administrative proceeding and to assume the defense
or prosecution, as the case may be, of any suit, action or proceeding pursuant
to the terms of and subject to the conditions set forth in Section 5.01 of this
Agreement, (y) making available to InfoCure, during normal business hours, and
within sixty (60) days of any written request therefor, all books, records and
information, and the assistance of all officers and employees, necessary or
useful in connection with any tax inquiry, audit, examination, investigation,
dispute, litigation or any other matter, and (z) the use of its best efforts in
defending InfoCure's interests in any tax inquiry, audit, examination,
investigation, dispute, litigation or other matter for which PracticeWorks is
the Controlling Party.

                  (c)      REMEDY FOR FAILURE TO COMPLY. If PracticeWorks
reasonably determines that InfoCure is not for any reason fulfilling its
obligations under Section 6.02(a), or if InfoCure reasonably determines that
PracticeWorks is not for any reason fulfilling its obligations under Section
6.02(b), then InfoCure or PracticeWorks, as the case may be, shall have the
right to appoint, at the expense of the other, an independent entity such as a
nationally-recognized public accounting or law firm to assist the other in
meeting its obligations under this Section 6.02. Such entity shall have complete
access, during normal business hours to all books, records and information, and
the complete cooperation of all officers and employees, of InfoCure or
PracticeWorks, as the case may be. The remedy provided in this Section 6.02(c)
shall not be deemed exclusive.

                                  ARTICLE VII.

                          RETENTION OF RECORDS; ACCESS

         The InfoCure Group and the PracticeWorks Group shall (a) in accordance
with their then current record retention policy, retain records, documents,
accounting data and other information (including computer data) necessary for
the preparation and filing of all Tax Returns in respect of Taxes of the
InfoCure Group or the PracticeWorks Group for any Period Before Distribution or
for the audit of such Tax Returns; and (b) give to the other reasonable access
to such records, documents, accounting data and other information (including
computer data) and to its personnel (insuring their cooperation) and premises,
for the purpose of the review or audit of such Tax Returns to the extent
relevant to an obligation or liability of a party under this Agreement. At any
time after the Date of Distribution that the PracticeWorks Group proposes to
destroy such material or information, they shall first notify the InfoCure Group
in writing and the InfoCure Group shall be entitled to receive such materials or
information proposed to be destroyed.

                                 ARTICLE VIII.

                                    DISPUTES

         If InfoCure and PracticeWorks cannot agree on any calculation of any
liabilities under this Agreement, such calculation shall be made by any
independent public accounting firm acceptable to both InfoCure and
PracticeWorks. The decision of such firm shall be final and binding. The fees
and expenses incurred in connection with such calculation shall be borne by the
party that such independent public accounting firm determines has lost the
dispute.

                                  ARTICLE IX.

                           TERMINATION OF LIABILITIES

         Notwithstanding any other provision in this Agreement, any liabilities
determined under this Agreement shall not terminate any earlier than the
