THIS WARRANT AND THE SHARES ISSUABLE HEREUNDER HAVE NOT BEEN REGISTERED UNDER
THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, PLEDGED, OR
OTHERWISE TRANSFERRED WITHOUT AN EFFECTIVE REGISTRATION THEREOF UNDER SUCH ACT
OR PURSUANT TO RULE 144 OR AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE

                            WARRANT TO PURCHASE STOCK

Corporation:  CAMITRO CORPORATION, a California corporation
              -------------------    ----------
Number of Shares:
Class of Stock: Series B Preferred
Initial Exercise Price: $________per share
Issue Date:
Expiration Date:

     THIS WARRANT CERTIFIES THAT, for the agreed upon value of $1.00 and for
other good and valuable consideration, SILICON VALLEY BANK ("Holder") is
entitled to purchase the number of fully paid and nonassessable shares of the
class of securities (the "Shares") of the corporation (the "Company") at the
initial exercise price per Share (the "Warrant Price") all as set forth above
and as adjusted pursuant to Article 2 of this Warrant, subject to the provisions
and upon the terms and conditions set forth in this Warrant.

ARTICLE 1. EXERCISE.

     1.1 METHOD OF EXERCISE. Holder may exercise this Warrant by delivering a
duly executed Notice of Exercise in substantially the form attached as Appendix
1 to the principal office of the Company. Unless Holder is exercising the
conversion right set forth in Section 1.2, Holder shall also deliver to the
Company a check for the aggregate Warrant Price for the Shares being purchased.

     1.2 CONVERSION RIGHT. In lieu of exercising this Warrant as specified in
Section 1.1, Holder may from time to time convert this Warrant, in whole or in
part, into a number of Shares determined by dividing (a) the aggregate fair
market value of the Shares or other securities otherwise issuable upon exercise
of this Warrant minus the aggregate Warrant Price of such Shares by (b) the fair
market value of one Share. The fair market value of the Shares shall be
determined pursuant to Section 1.3.

     1.3 FAIR MARKET VALUE. If the Shares are traded in a public market, the
fair market value of the Shares shall be the closing price of the Shares (or the
closing price of the Company's stock into which the Shares are convertible)
reported for the business day immediately before Holder delivers its Notice of
Exercise to the Company. If the Shares are not traded in a public market, the
Board of Directors of the Company shall determine fair market value in its
reasonable good faith judgment. The foregoing notwithstanding, if Holder advises
the Board of Directors in writing that Holder disagrees with such determination,
then the Company and Holder shall promptly agree upon a reputable investment
banking firm to undertake such valuation. If the valuation of such investment
banking firm is greater than that determined by the

                                       2
<PAGE>   3

Board of Directors, then all fees and expenses of such investment banking firm
shall be paid by the Company. In all other circumstances, such fees and expenses
shall be paid by Holder.

     1.4 DELIVERY OF CERTIFICATE AND NEW WARRANT. Promptly after Holder
exercises or converts this Warrant, the Company shall deliver to Holder
certificates for the Shares acquired and, if this Warrant has not been fully
exercised or converted and has not expired, a new Warrant representing the
Shares not so acquired.

     1.5 REPLACEMENT OF WARRANTS. On receipt of evidence reasonably satisfactory
to the Company of the loss, theft, destruction or mutilation of this Warrant
and, in the case of loss, theft or destruction, on delivery of an indemnity
agreement reasonably satisfactory in form and amount to the Company or, in the
case of mutilation, on surrender and cancellation of this Warrant, the Company
shall execute and deliver, in lieu of this Warrant, a new warrant of like tenor.

     1.6 ASSUMPTION UPON SALE, MERGER, OR CONSOLIDATION OF THE COMPANY.

          1.6.1. "ACQUISITION." For the purpose of this Warrant, "Acquisition"
means any sale, license, or other disposition of all or substantially all of the
assets of the Company, or any reorganization, consolidation, or merger of the
Company where the holders of the Company's securities before the transaction
beneficially own less than 50% of the outstanding voting securities of the
surviving entity after the transaction.

          1.6.2. ASSUMPTION OF WARRANT. Upon the closing of any Acquisition the
successor entity shall assume the obligations of this Warrant and this Warrant
shall be exercisable for the same securities, cash, and property as would be
payable for the Shares issuable upon exercise of the unexercised portion of this
Warrant as if such Shares were outstanding on the record date for the
Acquisition and subsequent closing. The Warrant Price shall be adjusted
accordingly.

ARTICLE 2. ADJUSTMENTS TO THE SHARES.

     2.1 STOCK DIVIDENDS, SPLITS, ETC. If the Company (i) declares or pays a
dividend on its common stock (or the Shares if the Shares are securities other
than common stock) payable in common stock, or other securities, or (ii)
subdivides the outstanding common stock into a greater amount of common stock,
or, if the Shares are securities other than common stock, subdivides the Shares
in a transaction that increases the amount of common stock into which the Shares
are convertible, then upon exercise of this Warrant, for each Share acquired,
Holder shall receive, without cost to Holder, the total number and kind of
securities to which Holder would have been entitled had Holder owned the Shares
of record as of the date the dividend or subdivision occurred.

     2.2 RECLASSIFICATION, EXCHANGE OR SUBSTITUTION. Upon any reclassification,
exchange, substitution, or other event that results in a change of the number
and/or class of the securities issuable upon exercise or conversion of this
Warrant, Holder shall be entitled to receive, upon exercise or conversion of
this Warrant, the number and kind of securities and property that Holder would
have received for the Shares if this Warrant had been exercised immediately
before such reclassification, exchange, substitution, or other event. Such an
event shall include

                                       3
<PAGE>   4

any automatic conversion of the outstanding or issuable securities of the
Company of the same class or series as the Shares to common stock pursuant to
the terms of the Company's Articles of Incorporation upon the closing of a
registered public offering of the Company's common stock. The Company or its
successor shall promptly issue to Holder a new Warrant for such new securities
or other property. The new Warrant shall provide for adjustments which shall be
as nearly equivalent as may be practicable to the adjustments provided for in
this Article 2 including, without limitation, adjustments to the Warrant Price
and to the number of securities or property issuable upon exercise of the new
Warrant. The provisions of this Section 2.2 shall similarly apply to successive
reclassifications, exchanges, substitutions, or other events.

     2.3 ADJUSTMENTS FOR COMBINATIONS, ETC. If the outstanding shares are
combined or consolidated, by reclassification or otherwise, into a lesser number
of shares, the Warrant Price shall be proportionately increased.

     2.4 ADJUSTMENTS FOR DILUTING ISSUANCE. The Warrant Price and the number of
Shares issuable upon exercise of this Warrant or, if the Shares are Preferred
Stock, the number of shares of common stock issuable upon conversion of the
Shares, shall be subject to adjustment, from time to time in the manner set
forth in the Company's Articles (Certificate) of Incorporation. The provisions
set forth for the Shares in the Company's Articles (Certificate) of
Incorporation relating to the above in effect as of the Issue Date may not be
amended, modified or waived, without the prior written consent of Holder unless
such amendment, modification or waiver effects Holder in the same manner as they
effect all other shareholders of the Shares.

     2.5 NO IMPAIRMENT. The Company shall not, by amendment of its Articles of
Incorporation or through a reorganization, transfer of assets, consolidation,
merger, dissolution, issue, or sale of securities or any other voluntary action,
avoid or seek to avoid the observance or performance of any of the terms to be
observed or performed under this Warrant by the Company, but shall at all times
in good faith assist in carrying out of all the provisions of this Article 2 and
in taking all such action as may be necessary or appropriate to protect Holder's
rights under this Article against impairment. If the Company takes any action
affecting the Shares or its common stock other than as described above that
adversely affects Holder's rights under this Warrant, the Warrant Price shall be
adjusted upward in such a manner that the aggregate Warrant Price of this
Warrant is unchanged.

     2.6 FRACTIONAL SHARES. No fractional shares shall be issuable upon exercise
or conversion of the Warrant and the number of Shares to be issued shall be
rounded down to the nearest whole Share. If a fractional share interest arises
upon any exercise or conversion of the Warrant, the Company shall eliminate such
fractional share interest by paying Holder an amount computed by multiplying the
fractional interest by the fair market value of a full Share.

     2.7 CERTIFICATE AS TO ADJUSTMENTS. Upon each adjustment of the Warrant
Price, the Company at its expense shall promptly compute such adjustment, and
furnish Holder with a certificate of its Chief Financial Officer setting forth
such adjustment and the fact upon which such adjustment is based. The Company
shall, upon written request, furnish Holder a certificate setting forth the
Warrant Price in effect upon the date thereof and the series of adjustments
leading to such Warrant Price.

through any person or entity; provided, however, that by making the

Securities or Warrants for any minimum or other specific term and reserves the
right to dispose of the Registrable Securities or Warrants at any time pursuant
to the Registration Statement and in accordance with federal and state

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.
The Investor acknowledges that an investment in the Common Stock is speculative
and involves a high degree of risk.

                                       9
<PAGE>   10

         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

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 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

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.

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 Warrants because the Registrable Securities and
Warrants 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

                                       10
<PAGE>   11

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 Warrants 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 Warrants 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 Warrants
may be endorsed with a legend to this effect.

duly qualified as a foreign corporation to do business and is in good standing

corporate power and authority to enter into and perform its obligations under
this Agreement, the Registration Rights Agreement and the Warrants and to issue

authorization of the Company or its Board of Directors or stockholders is
required; and (iii) each of this Agreement and the Registration Rights Agreement
has been duly executed and delivered, and the Warrants at the time of their
delivery will be duly executed, issued and delivered, by the Company and at the

consents in lieu of meetings of the stockholders, the boards of directors and

Company nor any subsidiary has any of such minute books, stock transfer ledgers
and other similar records recorded, stored, maintained, operated or otherwise
wholly or partly dependent upon or held by any means (including any electronic,
mechanical or photographic process, whether computerized or not) which

convertible into or exchangeable for or giving any right to subscribe for any
shares of capital stock of the Company. All of the outstanding shares of Common
Stock of the Company have been duly and validly authorized and issued and are
fully paid and nonassessable. Following the Distribution, the outstanding
capital stock of the Company and options, warrants, or rights to subscribe to,

Act, as the case may be, and other federal, state and local laws, rules and
regulations applicable to such SEC Documents, and none of the SEC Documents
contained any untrue statement of a material fact or omitted to state a material

<PAGE>   14

preemptive or other rights to subscribe to or acquire the Capital Shares or
other securities of the Company. The Commitment Shares and the Warrant Shares
will not subject the Investor to personal liability by reason of the ownership
thereof. The Commitment Shares and Warrant Shares have been duly authorized by
the Company, but have not been issued (whether or not subsequently repurchased
by the Company) to any Person, and when issued to the Investor in accordance
with this Agreement and the Warrants will not have been issued (whether or not
subsequently repurchased by the Company) to any Person other than the Investor.

         Section 4.10.     No General Solicitation or Advertising. In regard to
the transactions contemplated hereby, neither the Company nor any of its
Affiliates nor any distributor or any person acting on its or their behalf (i)
has conducted or will conduct any general solicitation (as that term is used in
Rule 502(c) of Regulation D) or general advertising with respect to any of the
Commitment Shares, the Warrants, or the Warrant Shares, or (ii) made any offers
or sales of any security or solicited any offers to buy any security under any
circumstances that would require registration of the Common Stock under the
Securities Act.

of this Agreement by the Company and the consummation by the Company of the
transactions contemplated hereby, including without limitation the issuance of
the Commitment Shares, the Warrants and the Warrant Shares do not and will not
(i) result in a violation of the Certificate or By-Laws or (ii) conflict with,
or constitute a material default (or an event that with notice or lapse of time
or both would become a material default) under, or give to others any rights of
termination, amendment, acceleration or cancellation of, any material agreement,
indenture, instrument or any "lock-up" or similar provision of any underwriting
or similar agreement to which the Company is a party, or (iii) result in a
violation of any federal, state, local or foreign law, rule, regulation, order,
judgment or decree (including federal and state securities laws and regulations)
applicable to the Company or by which any property or asset of the Company is
bound or affected, nor is the Company otherwise in violation of, conflict with
or in default under any of the foregoing (except for such conflicts, defaults,
terminations, amendments, accelerations, cancellations and violations as would
not, individually or in the aggregate, have a Material Adverse Effect);
provided, however, that for purposes of the Company's representations and
warranties as to violations of foreign law, rule or regulation referenced in
clause (iii), such representations and warranties are made only to the best of
the Company's knowledge insofar as the execution, delivery and performance of
this Agreement by the Company and the consummation by the Company of the
transactions contemplated hereby are or may be affected by the status of the
Investor under or pursuant to any such foreign law, rule or regulation. The
business of the Company is not being conducted in violation of any law,
ordinance or regulation of any governmental entity, except for possible
violations that either singly or in the aggregate do not and will not have a
Material Adverse Effect. The Company is not required under federal, state or
local law, rule or regulation to obtain any consent, authorization or order of,
or make any filing or registration with, any court or governmental agency in
order for it to execute, deliver or perform any of its obligations under this
Agreement or issue and sell the Common Stock, the Commitment Shares, the
Warrants, or the Warrant Shares in accordance with the terms hereof (other than
any SEC, NASD or state securities filings that may be required to be made by the
Company subsequent to any Closing, any registration statement that may be filed
pursuant hereto, and any shareholder approval required by the rules applicable
to companies whose common stock trades on the Principal Market); provided that,
for purposes of the representation

                                       14

ordinary course of the Company's businesses since December 31, 1999 and which,
individually or in the aggregate, do not or would not have a Material Adverse
Effect on the Company.

         Section 4.14.     No Undisclosed Events or Circumstances. Since
December 31, 1999, no event or circumstance has occurred or exists with respect

condition, that, under applicable law, rule or regulation, requires public
disclosure or announcement prior to the date hereof by the Company but which has
not been so publicly disclosed or announced.

         Section 4.15.     No Integrated Offering. Neither the Company, nor any
of its Affiliates, nor any person acting on its or their behalf has, directly or
indirectly, made any offers or sales of any security or solicited any offers to
buy any security under circumstances that would require registration of the
Common Stock, the Commitment Shares, the Warrants or the Warrant Shares under
the Securities Act.

         Section 4.16.     Litigation and Other Proceedings. Except as set forth
in the SEC Documents, there are no lawsuits or proceedings pending or to the

other Person selling or offering to sell the Commitment Shares, the Warrants or
the Warrant Shares in connection with the transactions contemplated by this
Agreement, have not made, at any time, any communication in connection with the
offer or sale of the same which contained any untrue statement of a material
fact or omitted to state any material fact necessary in order to make the
statements, in the light of the circumstances under which they were made, not
misleading.

         Section 4.18.     Material Non-Public Information. The Company is not
in possession of, nor has the Company or its agents disclosed to the Investor,
any material non-public information that (i) if disclosed, would, or could

securities to one or more investors, other than a Strategic Investor, in
placements exempt from registration under the Securities Act until 60 calendar
days after this agreement is terminated pursuant to Section 2.5 hereof (the
"Exclusivity Period"). If the Company, for the purpose of obtaining any
additional financing, wishes to sell shares of its securities in placements
exempt from registration under the Securities Act during the Exclusivity Period
(a "Third Party Sale") to a party other than a Strategic Investor and other than
the Investor (the "Third Party"), the Company shall first offer (the "Offer") to
the Investor, in writing, the right to purchase such shares (the "Offered
Shares") at the bona fide price offered by the Third Party (the "Offer Price").
The Offer shall grant the Investor the right during the 5 Trading Days
immediately following the date of the Offer to elect to purchase any or all of
the Offered Shares. The Company, in connection with such a Third Party Sale,
shall refrain from circumventing or attempting to circumvent the Investor's
right of first refusal by way of making such a Third Party Sale to any of its
Affiliates without first making an Offer to the Investor. If the Investor so
exercises its right to purchase any or all of the Offered Shares, the purchase
will be treated as a Subsequent Sale except that the purchase price for the
Offered Shares shall be the Offer Price. The closing and method of payment shall
be as provided for in Sections 2.3 and 2.4 hereof and the Closing Date shall be
7 Trading Days after the Investor exercises such right. 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

                                       18
<PAGE>   19

payable on terms and conditions that are not more favorable to such purchaser
than those contained in the Offer. In the event that the Company effects a Third
Party Sale other than in accordance with this Section 6.12, the Investor may
immediately terminate this Agreement.

         Section 6.13.     Public Announcements. The Company, its
Representatives and legal advisors, and the Investor will not issue or make any
reports, statements or releases to the public or to any third party with respect
to this Agreement or the transactions contemplated hereby without the consent of
both the Company and the Investor, which consent shall not be unreasonably
withheld. The Company, its Representatives and legal advisers, and the Investor
also will obtain the other party's prior approval of any press release to be
issued announcing the consummation of the transactions 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 obligations, then such
party may make or issue the legally required report, statement, or press or
other release and promptly furnish the other party with a copy thereof.

                  or withdrawn the effectiveness of a Registration Statement,
                  either temporarily or permanently, or intends or has
                  threatened to do so (unless the SEC's concerns have been

                  effectiveness of such Registration Statement or related

                  performed, satisfied and complied in all respects with all
                  covenants, agreements and conditions required by this
                  Agreement, the Registration Rights Agreement and the Warrants
                  to be performed, satisfied or complied with by the Company at
                  or prior to each Condition Satisfaction Date.

                  (e)      No Injunction. No statute, rule, regulation,
                  executive order, decree, ruling or injunction shall have been
                  enacted, entered, promulgated or adopted by any court or
                  governmental authority of competent jurisdiction that
                  prohibits the transactions contemplated by this Agreement or
                  otherwise has a Material Adverse Effect, and no actions, suits
                  or proceedings shall be in progress, pending or threatened by
                  any Person, that seek to enjoin or prohibit the transactions
                  contemplated by this Agreement or otherwise could reasonably
                  be expected to have a Material Adverse Effect. For purposes of
                  this paragraph (e), no proceeding shall be deemed pending or
                  threatened unless one of the parties has received written or
                  oral notification thereof prior to the applicable Closing
                  Date.

                  (f)      No Suspension of Trading in or Delisting of Common
                  Stock. The trading of the Common Stock shall not have been
                  suspended by the SEC, the Principal Market or the NASD, and
                  the Common Stock shall have been approved for listing

                                       20
<PAGE>   21

                  or quotation on and shall not have been delisted from the
                  Principal Market. The issuance of shares of Common Stock with
                  respect to the applicable Closing shall not violate the
                  shareholder approval requirements of the Principal Market.

                  (g)      Legal Opinion. The Company shall have caused to be
                  delivered to the Investor, within 5 Trading Days of the
                  effective date of a Registration Statement, an opinion of the
                  Company's independent counsel in the form of Exhibit F hereto,
                  addressed to the Investor.

                  (h)      Due Diligence. No dispute between the Company and the
                  Investor shall exist pursuant to Section 7.3 as to the
                  adequacy of the disclosure contained in the Registration
                  Statement.

                  (i)      Ten Percent Limitation. On each Closing Date, the
                  number of Commitment Shares then to be purchased by the
                  Investor shall not exceed the number of such shares that, when
                  aggregated with all other shares of Common Stock and
                  Registrable Securities then owned by the Investor beneficially
                  or deemed beneficially owned by the Investor, as determined in
                  accordance with the definition of beneficial ownership in Rule
                  13d-3 promulgated under the Exchange Act, would result in the
                  Investor owning no more than 9.9% of all of such Common Stock
                  as would be outstanding on such Closing Date, as determined in
                  accordance with Section 13(d) of the Exchange Act and the
                  regulations promulgated thereunder. For purposes of this
                  Section, in the event that the amount of Common Stock
                  outstanding as determined in accordance with Section 13(d) of
                  the Exchange Act and the regulations promulgated thereunder is
                  greater on a Closing Date than on the Sale Notice Date
                  associated with such Closing Date, the amount of Common Stock
                  outstanding on such Closing Date shall govern for purposes of
                  determining whether the Investor, when aggregating all
                  purchases of Common Stock made pursuant to this Agreement and,
                  if any, Warrant Shares would own more than 9.9% of the Common
                  Stock following such Closing Date.

                  (j)      No Knowledge. The Company shall have no knowledge of
                  any event more likely than not to have the effect of causing
                  any Registration Statement to be suspended or otherwise
                  ineffective (which event is more likely than not to occur
                  within the fifteen Trading Days following the Trading Day on
                  which such notice is deemed delivered).

                  (k)      Minimum Time Interval. The Minimum Time Interval
                  shall have elapsed.

                  (l)      Shareholder Vote. The issuance of shares of Common
                  Stock with respect to the applicable Closing, if any, shall
                  not violate the shareholder approval requirements of the
                  Principal Market. Following each Sale Notice, the Company
                  shall promptly provide the Investor with a written schedule
                  stating as of such applicable Sale Notice Date (i) the total
                  number of shares of Outstanding Common Stock, (ii) the number
                  of Subsequent Sale Shares issuable with respect to the
                  applicable Closing, (iii) the number of First Sale Shares
                  issued, (iv) the

                                       21
<PAGE>   22

                  number of Protective Warrant Shares issued or issuable, if
                  any, and (v) the number of Incentive Warrant Shares issued or
                  issuable, if any. If the issuance by the Company of a number
                  of shares of Common Stock equal to the sum of the amounts
                  stated in clauses (ii) through (v), inclusive, hereof would
                  result in a violation by the Company of the shareholder
                  approval requirements of the Principal Market, the applicable
                  Sale Notice shall be deemed null and void.

                  (m)      Other. On each Condition Satisfaction Date, the
                  Investor shall have received and been reasonably satisfied
                  with such other certificates and documents as shall have been
                  reasonably requested by the Investor in order for the Investor
                  to confirm the Company's satisfaction of the conditions set
                  forth in this Section 7.2., including, without limitation, a
                  certificate in substantially the form and substance of Exhibit
                  G hereto, executed in either case by an executive officer of
                  the Company and to the effect that all the conditions to such
                  Closing shall have been satisfied as at the date of each such
                  certificate.

         Section 7.3.      Due Diligence Review; Non-Disclosure of Non-Public
Information.

                  (a)      The Company shall make available for inspection and
                  review by the Investor, advisors to and representatives of the
                  Investor (who may or may not be affiliated with the Investor
                  and who are reasonably acceptable to the Company), and any
                  Underwriter, any Registration Statement or amendment or
                  supplement thereto or any blue sky, NASD or other filing, all
                  financial and other records, all SEC Documents and other
                  filings with the SEC, and all other corporate documents and
                  properties of the Company as may be reasonably necessary for
                  the purpose of such review, and cause the Company's officers,
                  directors and employees to supply all such information
                  reasonably requested by the Investor or any such
                  representative, advisor or Underwriter in connection with such
                  Registration Statement (including, without limitation, in
                  response to all questions and other inquiries reasonably made
                  or submitted by any of them), prior to and from time to time
                  after the filing and effectiveness of such Registration
                  Statement for the sole purpose of enabling the Investor and
                  such representatives, advisors and Underwriters and their
                  respective accountants and attorneys to conduct initial and
                  ongoing due diligence with respect to the Company and the
                  accuracy of such Registration Statement.

                  (b)      None of the Company, its officers, directors,
                  employees and agents shall in any event disclose non-public
                  information to the Investor, advisors to or representatives of
                  the Investor unless prior to disclosure of such information
                  the Company identifies such information as being non-public
                  information and provides the Investor, such advisors and
                  representatives with the opportunity to accept or refuse to
                  accept such non-public information for review. As a condition
                  to disclosing any non-public information hereunder, the
                  Company may require the Investor's advisors and
                  representatives to enter into a confidentiality agreement in
                  form reasonably satisfactory to the Company and the Investor.

                  (c)      Nothing herein shall require the Company to disclose
                  non-public information to the Investor or its advisors or
                  representatives, and the Company represents that it does not
                  disseminate non-public information to any investors who
                  purchase stock in the Company in a public offering, to money
                  managers or to securities analysts, absent a confidentiality
                  agreement between the Company and such parties; provided,
                  however, that notwithstanding anything herein to the contrary,
                  the Company shall, as hereinabove provided, immediately notify
                  the advisors and representatives of the Investor and any
                  Underwriters of any event or the existence of any circumstance
                  (without any obligation to disclose the specific event or
                  circumstance) of which it becomes aware, constituting
                  non-public information (whether or not requested of the
                  Company specifically or generally during the course of due
                  diligence by such persons or entities), which, if not
                  disclosed in the prospectus included in the applicable
                  Registration Statement would cause such prospectus to include
                  a material misstatement or to omit a material fact required to
                  be stated therein in order to make the statements, therein, in
                  light of the circumstances in which they were made, not
                  misleading. Nothing contained in this Section 7.3 shall be
                  construed to mean that such persons or entities other than the
                  Investor (without the written consent of the Investor prior to
                  disclosure of such information) may not obtain non-public
                  information in the course of conducting due diligence in
                  accordance with the terms and conditions of this Agreement and
                  nothing herein shall prevent any such persons or entities from
                  notifying the Company of their opinion that based on such due
                  diligence by such persons or entities, that such Registration
                  Statement contains an untrue statement of a material fact or
                  omits a material fact required to be stated in such
                  Registration Statement or necessary to make the statements
                  contained therein, in light of the circumstances in which they
                  were made, not misleading.

                                  ARTICLE VIII

                                     LEGENDS

         Section 8.1.      Legends. Each of the Warrants 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
         UNDER THE SECURITIES ACT OR PURSUANT TO A TRANSACTION

                                       23
<PAGE>   24

         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."

         On the Subscription Date 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) Transfer Agent Instructions, 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 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; 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; or

                  (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 8.2.      No Other Legend or Stock Transfer Restrictions. No
legend other than the one specified in Section 8.1 has been or shall be placed
on the share certificates representing the Registrable Securities, and no
instructions or "stop transfer orders," so called, "stock transfer
restrictions," or other restrictions have been or shall be given to the
Company's transfer agent with respect thereto other than as expressly set forth
in this Article VIII.

         Section 8.3.      Investor's Compliance. Nothing in this Article
VIII shall affect in any way the Investor's obligations to comply with all
applicable securities laws.

                          INDEMNIFICATION; ARBITRATION

         Section 9.1.      Indemnification.

                  (a) The Company agrees to indemnify and hold harmless the
                  Investor, 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 Investor, 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 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 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 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 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

         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
                           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),

                           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 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

                                       27
<PAGE>   28

                           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 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, the Registration Rights
Agreement or the Warrants, 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.

StockTrans, Inc.

Attention: Jonathan E. Miller

Dear Mr. Miller:

         Reference is made to the Stock Purchase Agreement (the "Agreement"),
dated as of [DATE] between Crescent International Limited (the "Investor") and
PracticeWorks, Inc. (the "Company"). Pursuant to the Agreement, the Investor has
agreed to purchase from the Company and the Company has agreed to sell to the
Investor from time to time shares of Common Stock of the Company (the "Common
Stock"). As a condition to the effectiveness of the Agreement, the Company has
agreed to issue to you, as the transfer agent for the Common Stock (the
"Transfer Agent"), these instructions (the "Irrevocable Instructions") relating
to the Common Stock to be issued to the Investor (or a permitted assignee)
pursuant to the Agreement. Any term used herein and not otherwise defined shall
have the meaning set forth in the Agreement.

         1.       MECHANICS OF DELIVERY OF CERTIFICATES REPRESENTING COMMON
STOCK

         a. First Sale. Upon confirmation by the Investor of transfer of funds
due to the Company pursuant to the First Sale, the Transfer Agent shall deliver
to the Investor by overnight courier certificates representing Common Stock as
promptly as practicable, but in no event later than three business days after
the Closing Date relating to the First Sale.

         b. Subsequent Sales. The Transfer Agent shall deliver to the Investor
by overnight courier certificates representing Common Stock as promptly as
practicable, but in no event later than three business days after any Closing
pursuant to which the Investor acquires Common Stock under the Agreement, or
after any request that a Legend be removed.

         c. Address. Unless otherwise notified in writing by the Investor, the
certificates delivered to the Investor pursuant to the Agreement and the
preceding two paragraphs shall be delivered at the following address:

         [ADDRESS]

         With notice to:

         [ADDRESS]

                                       40
<PAGE>   41

         2.       ISSUANCE  OF COMMON STOCK WITHOUT THE LEGEND

         a. Pursuant to the Agreement, the Company is required to prepare and
file with the Commission, and maintain the effectiveness of, a registration
statement or registration statements registering the resale of the Common Stock
acquired or to be acquired by the Investor. The Company will advise the Transfer
Agent in writing of the effectiveness of any such registration statement
promptly upon its being declared effective. The Transfer Agent shall be entitled
to rely on such advice and shall assume that such registration statement remains
effective unless the Transfer Agent is otherwise advised in writing by the
Company and shall not be required to independently confirm the continued
effectiveness of such registration statement. In the circumstances set forth in
paragraph (b) below, the Transfer Agent shall deliver to the Investor
certificates representing Common Stock not bearing the Legend without requiring
further advice or instruction or additional documentation from the Company or
its counsel or the Investor or its counsel or any other party (other than as
described in such paragraphs).

         b. At any time after the effective date of the applicable registration
statement (provided that the Company has not informed the Transfer Agent in
writing that such registration statement is not effective) upon any surrender of
one or more certificates evidencing Common Stock which bear the Legend,
accompanied by a notice from the Investor, its broker, custodian or permitted
assignee requesting the issuance of new certificates free of the Legend to
replace those surrendered and setting forth whether a transfer is pursuant to a
registration statement, Rule 144 or Rule 144(k), the Transfer Agent shall
promptly deliver to the Investor certificates representing the Common Stock not
bearing the Legend, in such names and denominations as requested, provided that:

         i.       if pursuant to a registration statement, the Investor (or its
         broker, custodian or permitted assignee) shall confirm in writing to
         the Transfer Agent that the Investor has complied with the prospectus
         delivery requirements under the Securities Act;

         ii.      if pursuant to Rule 144(k) the Investor (or its broker,
         custodian or permitted assignee) shall deliver to the Transfer Agent an
         opinion of counsel satisfactory to the Company, to the effect that the
         Investor is permitted to dispose of such Common Stock without
         limitation as to amount or manner of sale pursuant to Rule 144(k) under
         the Securities Act; or

         iii.     if pursuant to Rule 144, the Investor (or its broker,
         custodian or permitted assignee) shall deliver to the Transfer Agent an
         opinion of counsel satisfactory to the Company, to the effect that the
         Investor has complied with the manner of sale and notice requirements
         of Rule 144 under the Securities Act, as amended.

         Any advice, notice or instructions to the Transfer Agent required or
permitted to be given hereunder may be transmitted via facsimile to the Transfer
Agent's facsimile number of (610) 649-7302.

         3.       FEES OF TRANSFER AGENT; INDEMNIFICATION

         The Company agrees to pay the Transfer Agent for all fees and expenses
incurred in connection with these Irrevocable Instructions. The Company agrees
to indemnify the Transfer Agent and its officers, employees and agents, against
any losses, claims, damages or liabilities, joint or several, to which it or
they become subject based upon the performance by the Transfer Agent of its
duties in accordance with the Irrevocable Instructions.

         4.       THIRD PARTY BENEFICIARY

              FORM OF OPINION OF THE COMPANY'S INDEPENDENT COUNSEL

[Date]

Crescent International Ltd.
c/o GreenLight (Switzerland) SA
84, av Louis-Casai, P.O. Box 42
1216 Geneva, Cointrin
Switzerland

Re:      Stock Purchase Agreement Between Crescent International Ltd. and
PracticeWorks, Inc.

Ladies and Gentlemen:

         This opinion is furnished to you pursuant to Section [6.11] [7.2(g)] of
the Stock Purchase Agreement by and between Crescent International Ltd., a
Bermuda entity (the "Investor") and PracticeWorks, Inc., a Delaware corporation
(the "Company"), dated [DATE] (the "Stock Purchase Agreement"), which provides
for the issuance and sale by the Company of shares of Common Stock of the
Company (the "Commitment Shares"), a warrant to purchase a number of shares of
Common Stock of the Company to be determined in accordance with the terms of
such warrant (the "Incentive Warrant") and warrants to purchase a number of
shares of Common Stock of the Company to be determined in accordance with the
terms of such warrants (the "Protective Warrants", and together with the
Incentive Warrant, the "Warrants") (the shares of Common Stock issued or
issuable pursuant to exercise of the Warrants are referred to herein as the
"Warrant Shares"). All terms used herein have the meanings defined for them in
the Stock Purchase Agreement unless otherwise defined herein.

         We have acted as counsel for the Company in connection with the
negotiation of the Stock Purchase Agreement, the Warrants, and the Registration
Rights Agreement between the Investor and the Company, dated [DATE] (the
"Registration Rights Agreement" and together with the Stock Purchase Agreement,
the "Agreements"). As counsel, we have made such legal and factual examinations
and inquires as we have deemed advisable or necessary for the purpose of
rendering this opinion. In addition, we have examined, among other things,
originals or copies of such corporate records of the Company, certificates of
public officials and such other documents and questions of law that we consider
necessary or advisable for the purpose of rendering this opinion. In such
examination we have assumed the genuineness of all signatures on original
documents, the authenticity and completeness of all documents submitted to us as
originals, the conformity to original documents of all copies submitted to us as
copies thereof, the legal capacity of natural persons, and the due execution and
delivery of all documents (except as to due execution and delivery by the
Company) where due execution and delivery are a prerequisite to the
effectiveness thereof.

         As used in this opinion, the expression "to our knowledge" refers to
the current actual knowledge of the attorneys of this firm who have worked on
matters for the Company solely in connection with the Agreements and the
Warrants and the transactions contemplated thereby.

                                       43
<PAGE>   44

         For purposes of this opinion, we have assumed that you have all
requisite power and authority, and have taken any and all necessary corporate
action, to execute and deliver the Agreements, and we are assuming that the
representations and warranties made by the Investor in the Agreements and
pursuant thereto are true and correct.

         Based upon and subject to the foregoing, we are of the opinion that:

         1.       The Company is a corporation duly organized, validly existing
and in good standing under the laws of the State of Delaware and has all
requisite power and authority (corporate and other) to carry on its business and
to own, lease and operate its properties and assets as described in the
Company's SEC Documents. To our knowledge, the Company does not own more than
fifty percent (50%) of the outstanding capital stock of or control any other
business entity. The Company is duly qualified as a foreign corporation to do
business and is in good standing in every jurisdiction in which the Company owns
or leases property, other than those in which the failure so to qualify would
not have a Material Adverse Effect.

         2.       The Company has the requisite corporate power and authority to
enter into and perform its obligations under the Agreements and the Warrants and
to issue the Commitment Shares, the Warrants and the Warrant Shares. The
execution and delivery of the Agreements, and the execution, issuance and
delivery of the Warrants, by the Company and the consummation by it of the
transactions contemplated thereby have been duly authorized by all necessary
corporate action and no further consent or authorization of the Company or its
Board of Directors or stockholders is required. Each of the Agreements has been
duly executed and delivered, and the Warrants have been, and upon issuance will
be, duly executed, issued and delivered, by the Company and each of the
Agreements and the Warrants constitutes, and upon issuance will constitute,
valid and binding obligations of the Company enforceable against the Company in
accordance with their respective terms, except as such enforceability may be
limited by 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.

         3.       The execution, delivery and performance of the Agreements and
the Warrants by the Company and the consummation by the Company of the
transactions contemplated thereby, including without limitation the issuance of
the Commitment Shares, the Warrant and the Warrant Shares, do not and will not
(i) result in a violation of the Company's Certificate or Bylaws; (ii) to our
knowledge, conflict with, or constitute a material default (or an event that
with notice or lapse of time or both would become a default) under, or give to
others any rights of termination, amendment, acceleration or cancellation of,
any material agreement, indenture, instrument or any "lock-up" or similar
provision of any underwriting or similar agreement to which the Company is a
party, except for such conflicts, defaults, terminations, amendments,
accelerations and cancellations as would not, individually or in the aggregate,
have a Material Adverse Effect; or (iii) result in a violation of any federal or
state law, rule or regulation applicable to the Company or by which any property
or asset of the Company is bound or affected, except for such violations as
would not, individually or in the aggregate, have a Material Adverse Effect. To
our knowledge, the Company is not in violation of any terms of its Certificate
or Bylaws.

                                       44
<PAGE>   45

         4.       The issuance of the Commitment Shares and the Warrants in
accordance with the Stock Purchase Agreement, and the issuance of the Warrant
Shares in accordance with the Warrants, will be exempt from registration under
the Securities Act of 1933 and will be in compliance with Delaware state
securities laws. When so issued, the Commitment Shares and the Warrant Shares
will be duly and validly issued, fully paid and nonassessable, and free of any
liens, encumbrances and preemptive or similar rights contained in the
Certificate or Bylaws or, to our knowledge, in any agreement to which the
Company is party.

         5.       To our knowledge, except as disclosed in the SEC Documents,
there are no claims, actions, suits, proceedings or investigations that are
pending against the Company or its properties, or against any officer or
director of the Company in his or her capacity as such, nor has the Company
received any written threat of any such claims, actions, suits, proceedings, or
investigations which are required to be and have not been disclosed in the SEC
Documents.

         6.       To our knowledge, there are no outstanding options, warrants,
calls or commitments of any character whatsoever relating to, or securities,
rights or obligations convertible into or exchangeable for, or giving any right
to subscribe for or acquire any shares of Common Stock or contracts,
commitments, understanding, or arrangements by which the Company is or may
become bound to issue additional shares of Common Stock, or securities or rights
convertible or exchangeable into shares of Common Stock, except as described in
the SEC Documents.

         [7.      Nothing has come to our attention that has caused us to
believe that the Registration Statement and the Prospectus at the time the
Registration Statement became effective and as of the date of the filing with
the Commission of the Company's most recent Annual Report on Form 10-K or
Quarterly Report on Form 10-Q incorporated by reference into such Registration
Statement contained an untrue statement of a material fact or omitted to state a
material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which they were made, not
misleading; however, we express no opinion with respect to the financial
statements and the notes thereto and the schedules and other financial and
statistical data derived therefrom included in the Registration Statement or the
Prospectus.] [For Opinion pursuant to Section 7.2(g).]

         This opinion is furnished to the Investor solely for its benefit in
connection with the transactions described above and may not be relied upon by
any other person or for any other purpose without our prior written consent.

                                             Very truly yours,

                                       45
