                                    APPENDIX
                                     TO THE
                               PRACTICEWORKS, INC.
                           401(K) PROFIT SHARING PLAN
                                    EFFECTIVE
                               As of March 5, 2001
                  Grandfathered Optional Forms of Distribution

         Effective as of March 5, 2001, PracticeWorks was spun-off from InfoCure
in the form of a stock dividend (the "Spin-Off"). Prior to this Spin-Off,
InfoCure effected a number of corporate transactions with companies which
sponsored qualified retirement plans. As a result of these transactions, some
retirement plans were either merged with and into, or transferred assets and
liabilities to, the InfoCure Plan. These transactions and the resulting transfer
or merger of assets and liabilities from other retirement plans into the
InfoCure Plan required the retention in the InfoCure Plan of a number of
distribution options as well as other benefits, rights and features applicable
to certain account balances.

         As of the Effective Date, PracticeWorks adopted this Plan. As soon as
administratively feasible after the Spin-Off of PracticeWorks from InfoCure, the
assets and liabilities attributable to employees who became Employees of
PracticeWorks as a result of the Spin-Off, or who had an account balance in the
InfoCure Plan and previously worked for a company that is a part of
PracticeWorks after the Spin-Off were transferred from the InfoCure Plan to this
Plan. The purpose of this Appendix is to outline the distribution options that
were available under the InfoCure Plan and that have been retained for a limited
time in this Plan or that were available in a plan that will merge its assets
and liabilities with and into this Plan after the Spin-Off.

         Notwithstanding anything in the Plan to the contrary, the optional
methods of distribution available under the terms of this Appendix shall be
available only from a Participant's Transfer Account provided (i) his or her
vested Account balance exceeds $5,000 and (ii) the Participant makes an Election
to receive one of these optional forms of benefit prior to the earlier of:

         (a)      The 90th day after the date the Participant becomes eligible
                  to receive a distribution and the Plan Sponsor has provided
                  the Participant with a written explanation of the optional
                  methods of distribution available under the Plan and this
                  Appendix, or

         (b)      January 1, 2003.

         After (a) or (b) above become effective, the only method of
distribution available from the Plan shall be the method available in ss. 8.1,
without reference to the last paragraph of such Section.

                  (vii)    Any combination of the above, in cash or in-kind, or

         (b)      Special Rules for Annuity Contracts. If a UniDent Participant
                  makes an Election at any time that his or her Transfer Account
                  be paid in the form of an annuity, the rules of this Section
                  will apply to any withdrawal, loan or distribution from his or
                  her Transfer Account at that time or any future time.

                  (i)      Normal Annuity Form. Any distribution made to a
                           UniDent Participant (including withdrawals
                           under ss.8.3) will be paid

                           a) in the form of a single life annuity if he or she
                           does not have a spouse on the Annuity Starting Date,
                           or

                           b) in the form of a joint and 50% survivor annuity
                           with his or her spouse as beneficiary if he or she
                           has a spouse on his or her Annuity Starting Date

                           unless the UniDent Participant elects another form of
                           payment and his or her spouse, if any, consents to
                           that Election in accordance with this Section.

                  (ii)     Election Procedures for Annuity Benefits. If a
                           UniDent Participant elects that his or her Transfer
                           Account be paid in the form of an annuity, the
                           Company will (consistent with the regulations under
                           Code ss. 417) furnish him or her with a written
                           explanation of the normal annuity form, the optional
                           payment forms and his or her rights under Code ss.
                           401(a)(11), ss. 411(a)(11), and ss. 417.

                           A UniDent Participant who elects an annuity payment
                           form may waive the normal annuity form and select an
                           optional payment form on a properly completed
                           Election before his or her Annuity Starting Date. The
                           last properly completed Election before the UniDent
                           Participant's Annuity Starting Date will control the
                           payment of benefits under this Plan.

                           A UniDent Participant's Election to waive the normal
                           annuity form generally will not be effective unless
                           (A) the Election designates the form of payment, (B)
                           his or her spouse consents in writing to the waiver,
                           (C) the


                                      -3-
<PAGE>   4

                           spouse's consent acknowledges the effect of the
                           waiver, and (D) the spouse's consent is witnessed by
                           a Plan representative or a notary public.

                           However, if the UniDent Participant establishes to
                           the satisfaction of the Plan Sponsor and in
                           accordance with Code ss. 417 that written consent of
                           his or her spouse may not be obtained because there
                           is no spouse or the spouse cannot be located or
                           because of such other circumstances as may be
                           described in the regulations under Code ss. 417, the
                           UniDent Participant's Election will be deemed to be a
                           valid waiver.

                           A spouse's written consent will be irrevocable as to
                           that spouse and will be binding only as against that
                           spouse.

                           A UniDent Participant may revoke (without the consent
                           of his or her spouse) an election to waive the normal
                           annuity form by completing another Election at any
                           time prior to his or her Annuity Starting Date.

                  (iii)    Loans. A UniDent Participant who has elected to have
                           his or her Transfer Account paid in the form of an
                           annuity may not pledge his or her Transfer Account as
                           security for a loan under ss. 11 unless his or her
                           spouse, if any, consents to that pledge in a manner
                           described in this Section. No loan will be made to
                           the UniDent Participant in the absence of proper
                           spousal consent.

                  (iv)     Death Benefits. If a UniDent Participant who has
                           elected to have his or her Transfer Account paid in
                           the form of an annuity dies before his or her Annuity
                           Starting Date, his or her Transfer Account balance
                           will be applied to purchase a Preretirement Survivor
                           Annuity for his or her surviving spouse if the
                           UniDent Participant did not waive the Preretirement
                           Survivor Annuity in accordance with the waiver
                           procedures in this Section.

                  (v)      Definitions. For purposes of this Section, the
                           following terms will have the meanings set forth
                           below:

                           as an annuity under this Plan.

                           b) Preretirement Survivor Annuity - means an annuity
                           for the life of a UniDent Participant's surviving
                           spouse, that is equal to the maximum amount of
                           annuity benefit that can be purchased with the
                           UniDent Participant's Transfer Account as of the
                           Annuity Starting Date.

                           annuity form generally will not be effective unless

                           However, if the APSI Participant establishes to the
                           satisfaction of the Company and in accordance with
                           Code ss. 417 that written consent of his or her
                           spouse may not be obtained because there is no spouse
                           or the spouse cannot be located or because of such
                           other circumstances as may be described in the
                           regulations under Code ss. 417, the APSI
                           Participant's Election will be deemed to be a valid
                           waiver.

                           spouse.

                           An APSI Participant may revoke (without the consent
                           of his or her spouse) an election to waive the normal
                           annuity form by completing another Election at any
                           time prior to his or her Annuity Starting Date.

                  (iii)    Loans. An APSI Participant who has elected to have
                           his or her Transfer Account paid in the form of an
                           annuity may not pledge his or her Transfer Account as
                           security for a loan under ss. 11 unless his or her
                           spouse, if any, consents to that pledge in a manner
                           described in this Section. No loan will be made to
                           the APSI Participant in the absence of proper spousal
                           consent.

                  (iv)     Death Benefits. If an APSI Participant who has
                           elected to have his or her Transfer Account paid in
                           the form of an annuity dies before his or her Annuity
                           Starting Date, his or her Transfer Account balance
                           will be applied to purchase a Preretirement Survivor
                           Annuity for his or her surviving spouse if the APSI
                           Participant did not waive the Preretirement Survivor
                           Annuity in accordance with the waiver procedures in
                           ss. this 15.4(j).
