(whether or not legally binding) at any time to sell, assign, transfer, pledge,

term and reserves the right to dispose of the Registrable Securities or the
Preferred Stock at any time pursuant to the Registration Statement and in
accordance with federal and state securities laws applicable to such
disposition.

<PAGE>   6

         Section 3.2.  Sophisticated Investor. The Investor is a sophisticated
investor (as described in Rule 506(b)(2)(ii) of Regulation D) and an accredited
investor (as defined in Rule 501 of Regulation D), and the Investor has such
experience in business and financial matters that it is capable of evaluating
the merits and risks of an investment in the Common Stock and the Preferred
Stock. The Investor acknowledges that an investment in the Common Stock and the
Preferred Stock is speculative and involves a high degree of risk.

         Section 3.3.  Authority. Each of this Agreement and the Registration
Rights Agreement has been duly authorized by all necessary corporate action and
no further consent or authorization of the Investor, or its Board of Directors
or stockholders is required. Each of this Agreement and the Registration Rights
Agreement was validly executed and delivered by the Investor and each is a valid
and binding agreement of the Investor enforceable against it in accordance with
its terms, subject to applicable bankruptcy, insolvency, or similar laws
relating to, or affecting generally the enforcement of, creditors' rights and
remedies or by other equitable principles of general application.

         Section 3.4.  Not an Affiliate. The Investor is not an officer,
director or "affiliate" (as that term is defined in Rule 405 of the Securities
Act) of the Company.

         Section 3.5.  Organization and Standing. The Investor is duly
organized, validly existing, and in good standing under the laws of Bermuda.

         Section 3.6.  Absence of Conflicts. The execution and delivery of this
Agreement and any other document or instrument contemplated hereby, and the
consummation of the transactions contemplated thereby, and compliance with the
requirements thereof, will not to the Investor's knowledge (a) violate any law,
rule, regulation, order, writ, judgment, injunction, decree or award binding on
the Investor, (b) violate any provision of any indenture, instrument or
agreement to which the Investor is a party or is subject, or by which the
Investor or any of its assets is bound, (c) conflict with or constitute a
material default thereunder, (d) result in the creation or imposition of any
lien pursuant to the terms of any such indenture, instrument or agreement, or
constitute a breach of any fiduciary duty owed by the Investor to any third
party, or (e) require the approval of any third-party (that has not been
obtained) pursuant to any material contract to which the Investor is subject or
to which any of its assets, operations or management may be subject.

         Section 3.7.  Disclosure; Access to Information. The Investor has
received or had access to all documents, records, books and other information
pertaining to Investor's investment in the Company that have been requested by
Investor. The Investor has received and reviewed copies of the SEC Documents.

         Section 3.8.  Manner of Sale. At no time was Investor presented with or
solicited by or through any leaflet, public promotional meeting, television
advertisement or any other form of



                                       6
<PAGE>   7

general solicitation or advertising. The Investor has had an existing business
relationship with the Company or its Affiliates since September 1998 and the
Investor did not become aware of the Company as a result of the Company filing a
Form S-1 or Form 10 with the SEC, pursuant to which the Company plans to effect
the Distribution.

         Section 3.9.  Resale Restrictions. Investor acknowledges that any
Registrable Securities and the Preferred Stock to be acquired by Investor have
not been registered under the federal securities laws or any applicable state
securities laws in reliance upon exemptions available for non-public or limited
offerings. Investor understands that it must bear the economic risk of the
investment in the Registrable Securities and the Preferred Stock because the
Registrable Securities and the Preferred Stock have not been so registered and
therefore are subject to restrictions upon transfer such that they may not be
sold or otherwise transferred unless registered under the applicable securities
laws or an exemption from such registration is available. The Investor will not
reoffer, sell, assign, transfer, pledge, encumber, hypothecate or otherwise
dispose of any Registrable Securities or the Preferred Stock in the absence of
an effective registration statement, qualification or authorization relating
thereto under federal and applicable state securities laws or an opinion of
qualified counsel satisfactory to the Company to the effect that the proposed
transaction in the Registrable Securities or the Preferred Stock will neither
constitute or result in any violation of the federal or state securities laws.
Subject to Section 8.1 of this Agreement, any certificate or other document that
may be issued representing any shares of Registrable Securities or the Preferred
Stock may be endorsed with a legend to this effect.

                                   ARTICLE IV

additional financing, wishes to sell shares of its securities in placements
exempt from registration under the Securities Act during the Exclusivity Period

Investor (the "Third Party"), the Company shall first offer (the "Offer") to the

Shares. The Company, in connection with such a Sale, shall refrain from
circumventing or attempting to circumvent the Investor's right of first refusal
by way of making such a Sale to any of its Affiliates without first making an
Offer to the Investor. If the Investor fails to exercise its right to purchase
any or all of the Offered Shares, then during the 60 calendar days immediately
following the expiration of such right, the Company shall be free to sell any or
all of the Offered Shares to a purchaser for a purchase price not lower than the
Offer Price payable on terms and conditions that are not more favorable to such
purchaser than those contained in the Offer.

contemplated by this Agreement or in any way referring to the other party or
affiliates of the other party. If either party is unable to obtain the approval
of its public report, statement, or press or other release from the other party
and such report, statement, or press or other release is, in the advice of legal
counsel to such party, required by applicable law or by any rule or regulation
of the Principal Market, in order to discharge such party's disclosure

                                     LEGENDS

         Section 8.1. Legends. The Preferred Stock and, unless otherwise
provided below, each certificate representing Registrable Securities will bear
the following legend (the "Legend"):

         "THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
         UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES
         ACT"), OR ANY OTHER APPLICABLE SECURITIES LAWS AND HAVE BEEN ISSUED IN
         RELIANCE UPON AN EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE
         SECURITIES ACT AND SUCH OTHER SECURITIES LAWS. NEITHER THIS SECURITY
         NOR ANY INTEREST OR PARTICIPATION HEREIN MAY BE REOFFERED, SOLD,
         ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED, HYPOTHECATED OR OTHERWISE
         DISPOSED OF, EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT



                                       17
<PAGE>   18


         UNDER THE SECURITIES ACT OR PURSUANT TO A TRANSACTION THAT IS EXEMPT
         FROM, OR NOT SUBJECT TO, SUCH REGISTRATION. THE HOLDER OF THIS
         CERTIFICATE IS THE BENEFICIARY OF CERTAIN OBLIGATIONS OF THE COMPANY
         SET FORTH IN A STOCK PURCHASE AGREEMENT, DATED AS OF JANUARY __, 2001,
         BETWEEN PRACTICEWORKS, INC. AND CRESCENT INTERNATIONAL LTD. A COPY OF
         THE PORTION OF THE AFORESAID AGREEMENT EVIDENCING SUCH OBLIGATIONS MAY
         BE OBTAINED FROM PRACTICEWORKS, INC.'S EXECUTIVE OFFICES."

         At the Closing, the Company shall issue to the transfer agent for its
Common Stock (and to any substitute or replacement transfer agent for its Common
Stock upon the Company's appointment of any such substitute or replacement
transfer agent) instructions in substantially the form of Exhibit C hereto, with
a copy to the Investor. Other than as required as a result of change in law,
such instructions shall be irrevocable by the Company from and after the date
hereof or from and after the issuance thereof to any such substitute or
replacement transfer agent, as the case may be, except as otherwise expressly
provided in the Registration Rights Agreement. It is the intent and purpose of
such instructions, as provided therein, to require the transfer agent for the
Common Stock from time to time upon transfer of Registrable Securities by the
Investor to issue certificates evidencing such Registrable Securities free of
the Legend during the following periods and under the following circumstances
and without consultation by the transfer agent with the Company or its counsel
and without the need for any further advice or instruction or documentation to
the transfer agent by or from the Company or its counsel or the Investor:

                  (a) At any time after the applicable Effective Date, upon
         surrender of one or more certificates evidencing Preferred Stock or
         Common Stock that bear the Legend, to the extent accompanied by a
         notice requesting the issuance of new certificates free of the Legend
         to replace those surrendered; provided that (i) the applicable
         Registration Statement shall then be effective and (ii) if reasonably
         requested by the transfer agent the Investor confirms to the transfer
         agent that the Investor has transferred the Registrable Securities
         pursuant to such Registration Statement and has complied with the
         prospectus delivery requirement.

                  (b) At any time upon any surrender of one or more certificates
         evidencing Registrable Securities that bear the Legend, to the extent
         accompanied by a notice requesting the issuance of new certificates
         free of the Legend to replace those surrendered and containing
         representations that the Investor is permitted to dispose of such
         Registrable Securities without limitation as to amount or manner of
         sale pursuant to Rule 144(k) under the Securities Act.

         Section 9.1. Indemnification.

                  (a) The Company agrees to indemnify and hold harmless the
         Investor, its Affiliates, officers, directors, employees, and duly
         authorized agents, and each Person or entity, if any, who controls the
         Investor within the meaning of Section 15 of the Securities Act or
         Section 20 of the Exchange Act, together with its controlling persons
         from and against any Damages, joint or several, and any action in
         respect thereof to which the Investor, its Affiliates, officers,
         directors, employees, and duly authorized agents, and any such
         controlling person becomes subject to, resulting from, arising out of
         or relating to any misrepresentation, breach of warranty or
         nonfulfillment of or failure to perform any covenant or agreement on
         the part of the Company contained in this Agreement, as such Damages
         are incurred, unless such Damages result primarily from the Investor's
         gross negligence, recklessness or bad faith in performing its
         obligations under this Agreement; provided, however, that the maximum
         aggregate liability of the Company shall be limited to the amount
         actually invested by the Investor under this Agreement, and provided,
         further, that in no event shall this provision be deemed to limit any
         rights to indemnification arising under the Registration Rights
         Agreement.

                  (b) The Investor agrees to indemnify and hold harmless the
         Company, its partners, Affiliates, officers, directors, employees, and
         duly authorized agents, and each Person or entity, if any, who controls
         the Investor within the meaning of Section 15 of the Securities Act or
         Section 20 of the Exchange Act, together with its controlling persons
         from and against any Damages, joint or several, and any action in
         respect thereof to which the Company, its partners, Affiliates,
         officers, directors, employees, and duly authorized agents, and any
         such controlling person becomes subject to, resulting from, arising out
         of or relating to any misrepresentation, breach of warranty or
         nonfulfillment of or failure to perform any covenant or agreement on
         the part of the Investor contained in this Agreement, as such Damages
         are incurred, unless such Damages result primarily



                                       19
<PAGE>   20


         from the Company's gross negligence, recklessness or bad faith in
         performing its obligations under this Agreement; provided, however,
         that the maximum aggregate liability of the Investor shall be limited
         to the amount by which the total price at which the Registrable
         Securities of the Investor were sold to the public exceeds the amount
         actually paid by the Investor under this Agreement for such Registrable
         Securities sold to the public, and provided, further, that in no event
         shall this provision be deemed to limit any rights to indemnification
         arising under the Registration Rights Agreement.

         Section 9.2. Method of Asserting Indemnification Claims. All claims for
indemnification by any Indemnified Party (as defined below) under Section 9.1
shall be asserted and resolved as follows:

                  (a) In the event any claim or demand in respect of which any
         person claiming indemnification under any provision of Section 9.1 (an
         "Indemnified Party") might seek indemnity under Section 9.1 is asserted
         against or sought to be collected from such Indemnified Party by a
         person other than the Company, the Investor or any Affiliate of the
         Company (a "Third Party Claim"), the Indemnified Party shall deliver a
         written notification, enclosing a copy of all papers served, if any,
         and specifying the nature of and basis for such Third Party Claim and
         for the Indemnified Party's claim for indemnification that is being
         asserted under any provision of Section 9.1 against any person (the
         "Indemnifying Party"), together with the amount or, if not then
         reasonably ascertainable, the estimated amount, determined in good
         faith, of such Third Party Claim (a "Claim Notice") with reasonable
         promptness to the Indemnifying Party. If the Indemnified Party fails to
         provide the Claim Notice with reasonable promptness after the
         Indemnified Party receives notice of such Third Party Claim, the
         Indemnifying Party shall not be obligated to indemnify the Indemnified
         Party with respect to such Third Party Claim to the extent that the
         Indemnifying Party's ability to defend has been irreparably prejudiced
         by such failure of the Indemnified Party. The Indemnifying Party shall
         notify the Indemnified Party as soon as practicable within the period
         ending 30 calendar days following receipt by the Indemnifying Party of
         either a Claim Notice or an Indemnity Notice (as defined below) (the
         "Dispute Period") whether the Indemnifying Party disputes its liability
         or the amount of its liability to the Indemnified Party under Section
         9.1 and whether the Indemnifying Party desires, at its sole cost and
         expense, to defend the Indemnified Party against such Third Party
         Claim.

                           (i)      If the Indemnifying Party notifies the
                  Indemnified Party within the Dispute Period that the
                  Indemnifying Party desires to defend the Indemnified Party
                  with respect to the Third Party Claim pursuant to this Section
                  9.2(a), then the Indemnifying Party shall have the right to
                  defend, with counsel reasonably satisfactory to the
                  Indemnified Party, at the sole cost and expense of the
                  Indemnifying Party, such Third Party Claim by all appropriate
                  proceedings, which proceedings shall be vigorously prosecuted
                  by the Indemnifying Party to a final



                                       20

                  conclusion or will be settled at the discretion of the
                  Indemnifying Party (but only with the consent of the
                  Indemnified Party, in the case of any settlement that provides
                  for any relief other than the payment of monetary damages or
                  that provides for the payment of monetary damages as to which
                  the Indemnified Party shall not be indemnified in full
                  pursuant to Section 9.1). The Indemnifying Party shall have
                  full control of such defense and proceedings, including any
                  compromise or settlement thereof; provided, however, that the
                  Indemnified Party may, at the sole cost and expense of the
                  Indemnified Party, at any time prior to the Indemnifying
                  Party's delivery of the notice referred to in the first
                  sentence of this clause (i), file any motion, answer or other
                  pleadings or take any other action that the Indemnified Party
                  reasonably believes to be necessary or appropriate to protect
                  its interests; and provided further, that if requested by the
                  Indemnifying Party, the Indemnified Party will, at the sole
                  cost and expense of the Indemnifying Party, provide reasonable
                  cooperation to the Indemnifying Party in contesting any Third
                  Party Claim that the Indemnifying Party elects to contest. The
                  Indemnified Party may participate in, but not control, any
                  defense or settlement of any Third Party Claim controlled by
                  the Indemnifying Party pursuant to this clause (i), and except
                  as provided in the preceding sentence, the Indemnified Party
                  shall bear its own costs and expenses with respect to such
                  participation. Notwithstanding the foregoing, the Indemnified
                  Party may take over the control of the defense or settlement
                  of a Third Party Claim at any time if it irrevocably waives
                  its right to indemnity under Section 9.1 with respect to such
                  Third Party Claim.

                           (ii)     If the Indemnifying Party fails to notify
                  the Indemnified Party within the Dispute Period that the
                  Indemnifying Party desires to defend the Third Party Claim
                  pursuant to Section 9.2(a), or if the Indemnifying Party gives
                  such notice but fails to prosecute vigorously and diligently
                  or settle the Third Party Claim, or if the Indemnifying Party
                  fails to give any other notice required to be given within the
                  Dispute Period, then the Indemnified Party shall have the
                  right to defend, at the sole cost and expense of the
                  Indemnifying Party, the Third Party Claim by all appropriate
                  proceedings, which proceedings shall be prosecuted by the
                  Indemnified Party in a reasonable manner and in good faith or
                  will be settled at the discretion of the Indemnified Party
                  (with the consent of the Indemnifying Party, which consent
                  will not be unreasonably withheld). The Indemnified Party will
                  have full control of such defense and proceedings, including
                  any compromise or settlement thereof; provided, however, that
                  if requested by the Indemnified Party, the Indemnifying Party
                  will, at the sole cost and expense of the Indemnifying Party,
                  provide reasonable cooperation to the Indemnified Party and
                  its counsel in contesting any Third Party Claim which the
                  Indemnified Party is contesting. Notwithstanding the foregoing
                  provisions of this clause (ii), if the Indemnifying Party has
                  notified the Indemnified Party within the Dispute Period that
                  the Indemnifying Party disputes its liability or the amount of
                  its liability



                                       21
<PAGE>   22

                  hereunder to the Indemnified Party with respect to such Third
                  Party Claim, and if such dispute is resolved in favor of the
                  Indemnifying Party in the manner provided in clause (iii)
                  below, the Indemnifying Party will not be required to bear the
                  costs and expenses of the Indemnified Party's defense pursuant
                  to this clause (ii) or of the Indemnifying Party's
                  participation therein at the Indemnified Party's request, and
                  the Indemnified Party shall reimburse the Indemnifying Party
                  in full for all reasonable costs and expenses incurred by the
                  Indemnifying Party in connection with such litigation. The
                  Indemnifying Party may participate in, but not control, any
                  defense or settlement controlled by the Indemnified Party
                  pursuant to this clause (ii), and the Indemnifying Party shall
                  bear its own costs and expenses with respect to such
                  participation.

                           (iii)    If the Indemnifying Party notifies the
                  Indemnified Party that it does not dispute its liability or
                  the amount of its liability to the Indemnified Party with
                  respect to the Third Party Claim under Section 9.1 or fails to
                  notify the Indemnified Party within the Dispute Period whether
                  the Indemnifying Party disputes its liability or the amount of
                  its liability to the Indemnified Party with respect to such
                  Third Party Claim, the Damages in the amount specified in the
                  Claim Notice shall be conclusively deemed a liability of the
                  Indemnifying Party under Section 9.1 and the Indemnifying
                  Party shall pay the amount of such Damages to the Indemnified
                  Party on demand. If the Indemnifying Party has timely disputed
                  its liability or the amount of its liability with respect to
                  such claim, the Indemnifying Party and the Indemnified Party
                  shall proceed in good faith to negotiate a resolution of such
                  dispute, and if not resolved through negotiations within the
                  period of 30 calendar days immediately following the Dispute
                  Period, such dispute shall be resolved by arbitration in
                  accordance with Section 9.3.

                  (b) In the event any Indemnified Party should have a claim
         under Section 9.1 against the Indemnifying Party that does not involve
         a Third Party Claim, the Indemnified Party shall deliver a written
         notification of a claim for indemnity under Section 9.1 specifying the
         nature of and basis for such claim, together with the amount or, if not
         then reasonably ascertainable, the estimated amount, determined in good
         faith, of such claim (an "Indemnity Notice") with reasonable promptness
         to the Indemnifying Party. The failure by any Indemnified Party to give
         the Indemnity Notice shall not impair such party's rights hereunder
         except to the extent that the Indemnifying Party demonstrates that it
         has been irreparably prejudiced thereby. If the Indemnifying Party
         notifies the Indemnified Party that it does not dispute the claim or
         the amount of the claim described in such Indemnity Notice or fails to
         notify the Indemnified Party within the Dispute Period whether the
         Indemnifying Party disputes the claim or the amount of the claim
         described in such Indemnity Notice, the Damages in the amount specified
         in the Indemnity Notice will be conclusively deemed a liability of the
         Indemnifying Party under



                                       22
<PAGE>   23



         Section 9.1 and the Indemnifying Party shall pay the amount of such
         Damages to the Indemnified Party on demand. If the Indemnifying Party
         has timely disputed its liability or the amount of its liability with
         respect to such claim, the Indemnifying Party and the Indemnified Party
         shall proceed in good faith to negotiate a resolution of such dispute,
         and if not resolved through negotiations within the period of 30
         calendar days immediately following the Dispute Period, such dispute
         shall be resolved by arbitration in accordance with Section 9.3.

         Section 9.3. Arbitration. Any controversy, claim or dispute arising out
of or in connection with this Agreement or the Registration Rights Agreement,
including any question regarding its existence, validity, interpretation,
breach, or termination, shall be referred to and finally resolved in accordance
with the International Arbitration Rules of the American Arbitration
Association, and judgment upon the award rendered by the arbitral tribunal may
be entered by any court having jurisdiction thereof or having jurisdiction over
any party or any party's assets.

                  (a) The tribunal shall consist of three arbitrators, two of
         whom shall be appointed by the respective parties and the third, who
         shall be the chairperson of the tribunal, by the two party-appointed
         arbitrators within 30 days of the last of their appointments. Save
         that, if either party should fail to appoint an arbitrator within 30
         days of receiving written notice of the appointment of an arbitrator by
         the other party, the second arbitrator shall, at the written request of
         the party which has already made an appointment, be appointed forthwith
         by the American Arbitration Association. Likewise, if the
         party-appointed arbitrators fail to make an agreed appointment for the
         chairperson within 30 days of the last of their appointments, the
         chairperson shall, at the written request of either party, be appointed
         forthwith by the American Arbitration Association.

                  (b) The place of arbitration shall be New York, New York.

                  (c) This arbitration clause and the conduct of the arbitral
         proceedings shall be governed by the Federal Arbitration Act, 9
         U.S.C.A. sec. 1 et seq.

                  (d) The language of the arbitration shall be English.

                  (e) Nothing in these dispute resolution provisions shall be
         construed as preventing either party from seeking conservatory or
         similar interim relief in any court of competent jurisdiction.

                  (f) To the extent practicable, the arbitral tribunal shall
         render its award no more than 60 calendar days from the date that the
         three member tribunal is constituted. The arbitral tribunal shall not
         lose jurisdiction over the matter based on a failure to render an award
         within this time period.

(as defined below) are payable by the Company. The Investor is authorized by the
Company to retain and to pay, on behalf of the Company, the Closing Fees and

                  (a) Closing Fees. The Company shall pay certain fees (the
         "Closing Fees") to the payee entities in accordance with Schedule 10.1.

                  (b) Transaction Costs. The fees, expenses and disbursements of
         the Investor's counsel (the "Investor Legal Fees") shall be paid as
         follows: (i) the Investor shall pay the initial $10,000 of Investor
         Legal Fees and (ii) the Company shall pay all Investor Legal Fees in
         excess of $10,000, provided that the Company's share of Investor Legal
         Fees shall not exceed $50,000. The Company shall pay the Investor due
         diligence costs in connection with the consummation of this Agreement
         and the transactions contemplated hereby (the "Due Diligence Costs,"
         and together with the Investor Legal Fees, the "Transaction Costs"), up
         to a maximum amount of $5,000. The Company shall pay to the Investor
         the Company's share of the Transaction Costs on the Closing Date, to
         the extent such share of the Transaction Costs can be determined on the
         Closing Date. The Company shall pay its share of the remaining
         Transaction Costs to the Investor not later than ten days after receipt
         of notice from the Investor that such amount is due. The Company agrees

the parties hereto represents that it has had no dealings in connection with
this transaction with any finder or broker which would impose a legal obligation
to pay any fee or commission. The Company on the one hand, and the Investor, on
the other hand, agree to indemnify the other against and hold the other harmless
from any and all liabilities to any persons claiming brokerage commissions or
finder's fees on account of services purported to have been rendered on behalf
of the indemnifying party in connection with this Agreement or the transactions
contemplated hereby.

ineffective if it materially changes the economic benefit of this Agreement to
any party.

         Section 10.10. Title and Subtitles. The titles and subtitles used in
this Agreement are used for the convenience of reference and are not to be
