                  ---------------------------------------------

                                PROXYMED, INC.
                          COMMON STOCK PURCHASE WARRANT

                  ---------------------------------------------

                  This certifies that, for good and valuable consideration,
ProxyMed, Inc., a Florida corporation (the "Company"), grants to First Data
Corporation, a Delaware corporation (the "Warrantholder"), the right to
subscribe for and purchase from the Company, during the applicable Exercise
Period (as hereinafter defined), up to 600,000 validly issued, fully paid and
nonassessable shares, par value $0.001, of Common Stock of the Company (the
"Warrant Shares"), in three (3) annual allotments of 200,000 shares (each an
"Annual Allotment") at the exercise price per share of $16.50, subject to
adjustment pursuant to Section 5 hereof (the "Exercise Price"), all subject to
the terms, conditions and adjustments herein set forth. Capitalized terms used
herein shall have the meanings ascribed to such terms in Section 9 below.

                  1. ISSUANCE OF WARRANT; VESTING; DETERMINATION OF INCLUDED
REVENUE.

                           1.1 ISSUANCE OF WARRANT. This Warrant is issued
concurrently with and in consideration of the execution by First Data Resources
Inc., a Delaware corporation and a wholly-owned subsidiary of the Warrantholder
("FDR"), of the Commercial Agreement.

                           1.2 VESTING. The Warrantholder's right to exercise
each Annual Allotment shall become vested and exercisable if, and only if, the
following amounts of Included Revenue (as determined in accordance with Section
1.3) are achieved during the applicable Measurement Period:

          MEASUREMENT PERIOD      INCLUDED REVENUE     ANNUAL ALLOTMENT

       First Measurement Period      $10,000,000        200,000 shares

       Second Measurement Period     $20,000,000        200,000 shares

       Third Measurement Period      $30,000,000        200,000 shares
<PAGE>


Any right of exercise that has vested pursuant to this Section 1.2, but which
has not been exercised on or before the expiration of the applicable Exercise
Period (as defined in Section 2.1) shall become null and void and of no further
force or effect immediately at such expiration with no further action required
from either party.

                           1.3 DETERMINATION OF INCLUDED REVENUE. As promptly as
practicable, and in any event not later than the fifteenth day after each
Measurement Period, the Company's Chief Financial Officer ("CFO") shall deliver
to the Warrantholder a certificate (the "Annual Certification") setting forth in
reasonable detail the calculation of the amount of Included Revenue for the
applicable Measurement Period and a certification by the CFO that such
calculations are true and correct. The Annual Certification shall be conclusive
evidence of such Included Revenue, unless Warrantholder in good faith objects in
writing to the calculation of Included Revenue set forth in the Annual
Certification no later than five (5) Business Days after its receipt. The
foregoing written objection shall state with specificity any and all of the
grounds on which the Warrantholder objects. The Company and the Warrantholder
shall use their respective reasonable best efforts to resolve any such
objections within five (5) Business Days after the receipt by the Company of
Warrantholders objection. If the Company and the Warrantholder shall fail to
agree on the amount of Included Revenue for a particular Measurement Period
within such five (5) day period, the amount of Included Revenue for such
Measurement Period shall be determined by a certified public accountant ("CPA")
independent of the Company and the Warrantholder, chosen by the Board of
Directors and reasonably acceptable to the Warrantholder. The amount of Included
Revenue determined by the CPA shall be final and binding on each of the Company
and the Warrantholder. The cost of the CPA's certification shall be borne by the
Warrantholder unless the Included Revenue certified by the Company's CFO is
understated by more than five (5) percent, as compared to the Included Revenue
certified by the CPA, in which case the Company shall bear or reimburse the
Warrantholder for the cost of the CPA's certification of Included Revenue. The
Company and the Warrantholder shall cooperate to promptly provide the CPA with
such information as the CPA may reasonably request, and shall use their best
efforts to cause the CPA to complete its certification of Included Revenue
within twenty (20) days after engagement of the CPA.

                           1.4 TERM OF WARRANT. The term of this Warrant shall
commence on the date on which it is executed by the parties and shall expire on
the day after the last day of the Exercise Period following the Third
Measurement Period. The term of this Warrant shall not renew under any
circumstances.

                  2. EXERCISE OF WARRANT; PAYMENT OF TAXES.

                           2.1 EXERCISE OF WARRANT. Subject to the terms and
conditions set forth herein, provided Warrantholder's right to exercise has
vested pursuant to Section 1.2 of this Warrant, each Annual Allotment may be
exercised by the Warrantholder during the period commencing upon receipt of each
Annual Certification and ending on the later of (X) the sixtieth day following
the end of the preceding Measurement Period or (Y) if the CPA is engaged
pursuant to Section 1.3, the tenth day following the certification of the
Included Revenue by the CPA (the "Exercise Period"), provided that FDR is not
then in material breach of the Commercial Agreement, and further provided that

                                       2
<PAGE>

such exercise would not constitute a Prohibited Exercise, in which case the
Exercise Period shall be extended until the fifth Business Day following the
first date upon which such exercise would not constitute a Prohibited Exercise,
by:

                                    (a) the delivery to the Company of a duly
executed Exercise Form, and

                                    (b) the delivery of payment to the Company,
for the account of the Company, by wire transfer or any other means approved by
the Company, of the aggregate Exercise Price for exercise in lawful money of the
United States of America.

The Company agrees that the Warrant Shares shall be deemed to be issued to the
Warrantholder as the record holder of such Warrant Shares as of the close of
business on the date on which payment is made for the Warrant Shares as
aforesaid. For the avoidance of doubt, cashless exercises of the Warrant shall
not be permitted. Warrantholder shall also surrender this Warrant to the Company
upon the earlier of Warrantholder's permitted exercise in full of the third
Annual Allotment or the termination of this Warrant as per Section 1.4.

                           2.2 WARRANT SHARE CERTIFICATES. A stock certificate
or certificates for the Warrant Shares specified in each Exercise Form shall be
delivered to the Warrantholder within five (5) Business Days after receipt of
both the Exercise Form by the Company and the payment by the Warrantholder of
the aggregate Exercise Price.

                           2.3 PAYMENT OF TAXES. The Company will pay all
documentary stamp or other issuance taxes, if any, attributable to the issuance
of Warrant Shares upon the exercise of this Warrant; PROVIDED, HOWEVER, that the
Company shall not be required to pay any tax or taxes which may be payable in
respect of any transfer involved in the issue or delivery of any Warrants or
Warrant certificates or Warrant Shares in a name other than that of the then
Warrantholder as reflected upon the books of the Company.

                  3. RESTRICTIVE LEGEND. Except as otherwise permitted by this
Section 3, each Warrant (and each Warrant issued in substitution for any Warrant
pursuant to Section 6) shall be stamped or otherwise imprinted with a legend in
substantially the form as set forth on the cover of this Warrant.
Notwithstanding the foregoing, the Warrantholder may require the Company to
issue a Warrant or a certificate for Warrant Shares, in each case without a
legend, if either (i) such Warrant or such Warrant Shares, as the case may be,
have been registered for resale under the Securities Act, (ii) the Warrantholder
has delivered to the Company an opinion of legal counsel (from a firm reasonably
satisfactory to the Company) which opinion shall be addressed to the Company and
be reasonably satisfactory in form and substance to the Company's counsel, to
the effect that such registration is not required with respect to such Warrant
or such Warrant Shares, as the case may be or (iii) such Warrant or Warrant
Shares may be sold in accordance with Rule 144 of the Securities Act (or any
successor provision then in effect) under the Securities Act.

                                       3

                  4. RESERVATION AND REGISTRATION OF SHARES. The Company
covenants and agrees as follows:

                                    (a) All Warrant Shares that are issued upon
the exercise of this Warrant shall, upon issuance, be validly issued, fully-paid
and nonassessable, and not subject to any preemptive rights, and be free from
all taxes, liens, security interests, charges, and other encumbrances with
respect to the issuance thereof, other than taxes in respect of any transfer
occurring contemporaneously with such issue.

                                    (b) The Company shall at all times have
authorized and reserved, and shall keep available and free from preemptive
rights, a sufficient number of shares of Common Stock to provide for the
exercise of the rights represented by this Warrant.

                                    (c) The Company shall not, by amendment of
its Articles of Incorporation or through any reorganization, transfer of assets,
spin-off, consolidation, merger, dissolution, issue or sale of securities or any
other action or inaction, seek to avoid the observance or performance of any of
the terms of this Warrant, and shall at all times in good faith assist in
performing and giving effect to the terms hereof.

                  5. ANTI-DILUTION ADJUSTMENTS. The Exercise Price and the
number of Warrant Shares to be received upon exercise of this Warrant shall be
subject to adjustment as follows:

                           5.1 DIVIDEND, SUBDIVISION, COMBINATION OR
RECLASSIFICATION OF COMMON STOCK. In the event that the Company shall at any
time or from time to time, after the issuance of this Warrant but prior to the
full exercise of all Annual Allotments, (w) make a dividend or distribution on
the outstanding shares of Common Stock payable in Capital Stock, (x) subdivide
the outstanding shares of Common Stock into a larger number of shares, (y)
combine the outstanding shares of Common Stock into a smaller number of shares
or (z) issue any shares of its Capital Stock in a reclassification of the Common
Stock (other than any such event for which an adjustment is made pursuant to
another clause of this Section 5), then, and in each such case, (A) the
aggregate number of Warrant Shares for which this Warrant is exercisable (the
"Warrant Share Number") immediately prior to such event shall be adjusted (and
any other appropriate actions shall be taken by the Company) so that the
Warrantholder shall be entitled to receive upon exercise of this Warrant the
number of shares of Common Stock or other securities of the Company that it
would have owned or would have been entitled to receive upon or by reason of any
of the events described above, had this Warrant been exercised immediately prior
to the occurrence of such event and (B) the Exercise Price payable upon the
exercise of this Warrant shall be adjusted by multiplying such Exercise Price
immediately prior to such adjustment by a fraction, the numerator of which shall
be the number of Warrant Shares issuable upon the exercise of this Warrant
immediately prior to such adjustment, and the denominator of which shall be the
number of Warrant Shares issuable immediately thereafter. An adjustment made
pursuant to this Section 5.1 shall become effective retroactively (x) in the
case of any such dividend or distribution, to a date immediately following the
close of business on the record date for the determination of holders of shares
of Common Stock entitled to receive such dividend or distribution or (y) in the
case of any such subdivision, combination or reclassification, to the close of
business on the day upon which such corporate action becomes effective.

                           5.2 CERTAIN DISTRIBUTIONS. In case the Company shall
at any time or from time to time, after the issuance of this Warrant but prior
to the full exercise of all Annual

                                       4
<PAGE>

Allotments, distribute to all holders of shares of Common Stock (including any
such distribution made in connection with a merger or consolidation in which the
Company is the resulting or surviving Person and shares of Common Stock are not
changed or exchanged) cash, evidences of indebtedness of the Company or another
issuer, securities of the Company or another issuer or other assets (excluding
dividends or distributions payable in shares of Common Stock for which
adjustment is made under Section 5.1) or rights or warrants to subscribe for or
purchase any of the foregoing, THEN, and in each such case, (A) the Exercise
Price then in effect shall be adjusted (and any other appropriate actions shall
be taken by the Company) by multiplying the Exercise Price in effect prior to
the date of distribution by a fraction (i) the numerator of which shall be such
Current Market Price of Common Stock immediately prior to the date of
distribution less the then fair market value (as determined by the Board of
Directors in the exercise of their fiduciary duties) of the portion of the cash,
evidences of indebtedness, securities or other assets so distributed or of such
rights or warrants applicable to one share of Common Stock and (ii) the
denominator of which shall be the Current Market Price of the Common Stock
immediately prior to the date of distribution (but such fraction shall not be
greater than one) and (B) the Warrant Share Number shall be increased by being
multiplied by a fraction (i) the numerator of which shall be the Current Market
Price of one share of Common Stock immediately prior to the record date for the
distribution of such cash, evidences of indebtedness, securities, other assets
or rights or warrants and (ii) the denominator of which shall be the Current
Market Price of one share of Common Stock immediately prior to such record date
less the fair market value (as determined by the Board of Directors in the
exercise of their fiduciary duties) of the portion of such cash, evidences of
indebtedness, securities, other assets or rights or warrants so distributed.
Such adjustment shall be made whenever any such distribution is made and shall
become effective retroactively to a date immediately following the close of
business on the record date for the determination of stockholders entitled to
receive such distribution.

                           5.3 OTHER CHANGES. In case the Company at any time or
from time to time, after the issuance of this Warrant but prior to the full
exercise of all Annual Allotments, shall take any action affecting its Common
Stock similar to or having an effect similar to any of the actions described in
any of Sections 5.1, 5.2 or 5.7 (but not including any action described in any
such Section) and the Board of Directors in good faith determines that it would
be equitable in the circumstances to adjust the Exercise Price and Warrant Share
Number as a result of such action, then, and in each such case, the Exercise
Price and Warrant Share Number shall be adjusted in such manner and at such time
as the Board of Directors in good faith determines would be equitable in the
circumstances (such determination to be evidenced in a resolution, a certified
copy of which shall be mailed to the Warrantholder).

                           5.4 NO ADJUSTMENT; PAR VALUE MINIMUM. Notwithstanding
anything herein to the contrary, no adjustment under this Section 5 need be made
to the Exercise Price or Warrant Share Number if the company receives written
notice from the Warrantholder that no such adjustment is required.
Notwithstanding any other provision of this Warrant, the Exercise Price shall
not be adjusted below the par value of a share of Common Stock.

                           5.5 ABANDONMENT. If the Company shall take a record
of the holders of shares of its Common Stock for the purpose of entitling them
to receive a dividend or other distribution, and shall thereafter and before the
distribution to stockholders thereof legally abandon its plan to pay or deliver

                                       5
<PAGE>

such dividend or distribution, then no adjustment in the Exercise Price or
Warrant Share Number shall be required by reason of the taking of such record.

                           5.6 CERTIFICATE AS TO ADJUSTMENTS. Upon any
adjustment in the Exercise Price or Warrant Share Number, the Company shall
within a reasonable period (not to exceed ten (10) days) following any of the
foregoing transactions deliver to the Warrantholder a certificate, signed by (i)
the Chief Executive Officer of the Company and (ii) the Chief Financial Officer
of the Company, setting forth in reasonable detail the event requiring the
adjustment and the method by which such adjustment was calculated and specifying
the adjusted Exercise Price and Warrant Share Number then in effect following
such adjustment.

                           5.7 SPIN-OFF; REORGANIZATION, RECLASSIFICATION,
MERGER OR SALE TRANSACTION.

                                    (a) In case of any spin-off by the Company
of another Person (the "Spin-off Entity") at any time after the issuance of this
Warrant but prior to the exercise hereof, the Company shall issue to the
Warrantholder a new warrant, in form and substance satisfactory to the Company
and the Warrantholder, entitling the Warrantholder to purchase, at the exercise
price equal to the excess of the Exercise Price in effect immediately prior to
such spin-off over the adjusted Exercise Price pursuant to Section 5.2, the
number of shares of common stock or other proprietary interest in the Spin-off
Entity that the Warrantholder would have owned had the Warrantholder,
immediately prior to such spin-off, fully exercised any unexpired Annual
Allotment under this Warrant.

                                    (b) In case of any capital reorganization,
reclassification, Sale Transaction, merger or consolidation (other than a Sale
Transaction or a merger or consolidation of the Company in which the Company is
the surviving corporation) of the Company or other change of outstanding shares
of Common Stock (other than a change in par value, or from par value to no par
value, or from no par value to par value) (each, a "Transaction") at any time
after the issuance of this Warrant but prior to the exercise hereof, the Company
shall execute and deliver to the Warrantholder at least twenty (20) Business
Days prior to effecting such Transaction a certificate stating that,
notwithstanding the vesting requirements of Section 1.3, each unexpired Annual
Allotment shall be deemed to be vested and exercisable and the Warrantholder
shall have the right thereafter to exercise this Warrant for the kind and amount
of shares of stock or other securities, property or cash receivable upon such
Transaction by a holder of the number of shares of Common Stock into which this
Warrant could have been exercised immediately prior to such Transaction, and
provision shall be made therefor in the agreement, if any, relating to such
Transaction. Notwithstanding the immediately preceding sentence, if FDR elects
pursuant to the terms of the Commercial Agreement to terminate the Commercial
Agreement as a result of any Transaction, this Warrant and all rights to acquire
the unvested Annual Allotments shall terminate effective upon consummation of
such Transaction. Such certificate shall provide for adjustments which shall be
as nearly equivalent as may be practicable to the adjustments provided for in
this Section 5. The provisions of this Section 5.7 and any equivalent thereof in
any such certificate similarly shall apply to successive transactions.

                                       6

warrants are to be determined, or (B) the date on which such spin-off or
Transaction is expected to become effective and the date as of which it is

person in whose name this Warrant is registered as the holder and owner hereof
(notwithstanding any notations of ownership or writing hereon made by anyone
other than the Company) for all purposes and shall not be affected by any notice
