THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
AMENDED, NOR THE SECURITIES LAWS OF ANY STATE. THESE SECURITIES MAY NOT BE
SOLD, TRANSFERRED, OR OTHERWISE DISPOSED OF UNLESS A REGISTRATION STATEMENT IS
EFFECTIVE PERTAINING TO SAID SECURITIES OR UNLESS THE COMPANY HAS RECEIVED AN
OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT AN EXEMPTION FROM
REGISTRATION IS AVAILABLE.

                     VOID AFTER 5:00 P.M. NOVEMBER 15, 1999

FIELD (Amount) Warrants

                              WARRANT CERTIFICATE

             THIS CERTIFIES THAT, for value received, FIELD (NAME), or any
registered assigns (the "Holder"), is the owner of the number of warrants (the
"Warrants") specified above of RENEX CORP., a Florida corporation (the
"Company"). Each Warrant entitles the holder hereof to purchase, subject to the
terms and conditions set forth in this certificate one fully paid and
non-assessable share of the Company's Common Stock, $.001 par value (the
"Shares") commencing on the date hereof and continuing through November 15, 1999
(the "Exercise Period") upon the presentation and surrender of this Warrant
Certificate, with the form of election to purchase attached hereto, duly
executed, to the Company at its principal office, accompanied by payment of
$1.00 for every share of Common Stock so purchased hereunder (the "Exercise
Price"). The Exercise Price shall be payable in accordance with the provisions
of Section 2 herein.

             Each Warrant represented hereby is exercisable at the option of
the registered Holder, but no fractional shares of Common Stock will be issued
and the Holder may exercise only a whole number of Warrants. In lieu of
fractional shares of Common Stock, the Company shall pay to the holder hereof
an amount equal to the current value of such fraction computed (a) if the
Shares shall then be listed or admitted to trading on any national securities
exchange, on the basis of the last reported sale price of the Shares on such
exchange prior to the date of exercise, (b) if the Shares shall not then be so
listed or admitted, on the basis of the high bid price of the shares in the
over-the-counter market, as reported by NASDAQ or any successor thereto, on the
last business day prior to the date of exercise, or (c) if there is no market
for the Shares, the fair market value as determined in good faith by the
Company's Board of Directors. In the cash of the exercise of less than all of
the Warrants represented by this Warrant Certificate, the Company will cancel
this Certificate upon surrender thereof and shall execute and deliver a new
Warrant Certificate for the balance of such Warrants.

             The term "Expiration Date" shall mean 5:00 P.M. Eastern Standard
Time on November 15, 1999. If such date shall be a holiday or a day in which
banks are authorized to close, then the Expiration Date shall mean 5:00 P.M.
Eastern Standard Time, on the next following day which is not a holiday or a
day on which banks are authorized to close.

             Prior to due presentment for transfer of this Warrant Certificate,
the Company may deem and treat the person in whose name this Warrant
Certificate is registered on the books of the Company as the absolute owner
hereof for all purposes and that the Company shall not be affected by any
notice to the contrary.

             1.     ANTI-DILUTION ADJUSTMENTS.

                    (a) In case the Company shall at any time prior to the
Exercise of the Warrants declare a dividend or any distribution payable in any
class of the Company's Shares now outstanding or to be outstanding to which the
Exercise of the Warrants pertains, then the holder hereof, upon the Exercise of
the Warrants after the record date for the determination of holders of Shares
entitled to receive such dividend or distribution, shall be entitled to receive
upon Exercise of the Warrants, in addition to the number of Shares as to which
this Warrant Certificate is exercised, such additional Shares as such holder
would have received had the Warrants been exercised immediately prior to such
record date.



   2


                    (b) In case the Company shall at any time prior to the
Exercise of the Warrants effect a recapitalization or reclassification of such
character that the Shares shall be changed into or become exchangeable for a
larger or smaller number of Shares, then upon the effective date thereof, the
number of Shares which the holder hereof shall be entitled to purchase upon
Exercise of the Warrants shall be increased or decreased, as the case may be,
in direct proportion to the increase or decrease in the number of Shares by
reason of such recapitalization or reclassification, and the Purchase Price Per
Share of such recapitalized or reclassified Shares be proportionately decreased
and in the case of a decrease in the number of Shares, be proportionately
increased.

                    (c) Subject to the provisions contained in Paragraph 1(g)
herein, in case the Company shall at any time prior to the Exercise of the
Warrants issue or sell any Shares or any other securities convertible into
Shares or any options or warrants to purchase Shares (except as provided in
subsection (a) of this Paragraph 1) for a consideration per Share less than the
then current Purchase Price Per Share then forthwith upon such issue or sale
the Purchase Price Per Share (until another such issue or sale) shall be
reduced to a price (calculated to the nearest full cent) determined by dividing
(i) an amount equal to the sum of (A) the product obtained by multiplying (x)
the total number of Shares outstanding immediately prior to such issue or sale,
by (y) the Purchase Price Per Share in effect immediately prior to such issue
or sale plus (B) the aggregate amount of any consideration in connection with
such issue or sale, by (ii) the total number of Shares outstanding immediately
after such issue or sale. Simultaneously with such reduction in the Purchase
Price Per Share, the number of Shares issuable upon Exercise of the Warrants
shall be increased (to the nearest full Share) to the number obtained by
multiplying the Purchase Price Per Share in effective immediately prior to such
reduction by the number of Shares then issuable upon Exercise of the Warrants
and dividing the product so obtained by the reduced Purchase Price Per Share.
For purposes of this subsection 1(c) the consideration in connection with any
such issue or sale shall be the initial offering price for the sale of such
shares or other securities, options or warrants before deducting therefrom any
commissions or other expenses paid or incurred by the Company in connection
with the issue or sale of such securities, options or warrants plus any
additional cash receivable by the Company upon conversion or exercise of such
other securities, options or warrants, except that in the event that any
portion of such consideration is a consideration other than cash, the amount of
such consideration other than cash shall be the value thereof as determined in
good faith by the Board of Directors of the Company. In the event that the
conversion price or exercise price of any securities convertible into Shares or
options or warrants to purchase Shares is not specified at the time of the
issue or sale of such securities, options or warrants, the amount thereof, for
purposes only of this subsection 1(c), shall be as determined in good faith by
the Board of Directors of the Company. In the event of the issuance or sale by
the Company of any securities convertible into Shares or any options or
warrants to purchase Shares (except as provided in subsection (a) of this
Paragraph 1) the Company shall be deemed to have issued the maximum number of
Shares into which such convertible securities may be converted or the maximum
number of Shares deliverable upon the exercise of such options or warrants, as
the case may be. On the expiration of such options or warrants or the
termination of such right to convert, the Purchase Price Per Share shall be
readjusted based upon the number of Shares actually delivered upon the exercise
of such options or warrants or upon the conversion of such securities. Except
as provided in the preceding sentence, no further adjustment of the Purchase
Price Per Share shall be made as a result of the actual issuance of Shares upon
the exercise of such options or warrants or the conversion of such securities.

                    (d) In case the Company shall at any time prior to the
Exercise of the Warrants consolidate or merge with any other corporation or
transfer all or substantially all of its assets to any other corporation
preparatory to a dissolution, then the Company shall, as a condition precedent
to such transaction, cause effective provision to be made so that the holder
hereof upon the Exercise of the Warrants after the effective date of such
transaction shall be entitled to receive the kind and amount of shares,
evidences of indebtedness and/or other securities or property receivable on
such transaction by a holder of the number of Shares as to which this Warrant
were exercisable immediately prior to such transaction (without giving effect
to any restriction upon such exercise); and, in any such case, appropriate
provision shall be made with respect to the rights and interests of the holder
hereof to the end that the provisions of this Warrant shall thereafter be
applicable (as nearly as may be practicable) with respect to any Shares,
evidences of indebtedness or other securities or assets thereafter deliverable
upon Exercise of the Warrants.


                                      -2-

   3


                    (e) The term "Purchase Price Per Share" as used in this
Paragraph 1 shall mean the exercise price specified in this Warrant Certificate
until the occurrence of an event stated in subsection (b) or (c) of this
Paragraph 1 and thereafter shall mean said price as adjusted from time to time
in accordance with the provisions of said subsections. No such adjustment shall
be made unless such adjustment would change the then Purchase Price Per Share
by $.01 or more; provided, however, that all adjustments not so made shall be
deferred and made when the aggregate thereof would change the then Purchase
Price Per Share by $.01 or more. No adjustment made pursuant to any provision
of this Paragraph 1 shall have the effect of increasing the total consideration
payable upon Exercise of the Warrants in respect of all the Shares purchasable
hereunder.

                    (f) In the event that at any time, as a result of an
adjustment made pursuant to this Paragraph 1, the holder of this Warrant
Certificate shall become entitled to purchase upon Exercise of the Warrants,
shares, evidences of indebtedness or other securities or assets (other than
Shares) then, wherever appropriate, all references herein to Shares shall be
deemed to refer to and include such shares, evidences of indebtedness or other
securities or assets; and thereafter the number of such shares, evidences of
indebtedness or other securities or assets shall be subject to adjustment from
time to time in a manner and upon terms as nearly equivalent as practicable to
the provisions of this Paragraph 1.

                    (g) Notwithstanding anything herein to the contrary, no
adjustment shall be made to the Purchase Price Per Share or the number of
shares issuable upon Exercise of this Warrant upon the issuance of any
securities issued in connection with any of the following (i) incentive
compensation plans approved by the Company=s shareholders, (ii) upon grant of
options under any stock option plans approved by the corporation's shareholders
or the exercise and issuance of Common Stock thereunder, (iii) upon conversion
of any shares of preferred stock outstanding as of the date hereof and the
issuance of Common Stock pursuant thereto, (iv) exercise of any warrants,
rights or options outstanding as of the date hereof, (v) the sale and issuance
of common stock for a purchase price of not less than the then current Purchase
Price Per Share, or (vi) the sale or issuance of securities (including
preferred stock, options or warrants) convertible or exercisable into common
stock which securities conversion or exercise price is not less than the then
current Purchase Price Per Share .

             2. PAYMENT OF EXERCISE PRICE. The Exercise Price pursuant to this
Warrant or portion thereof, may be paid:

                    (i) in United States dollars, in cash or by check, bank
draft or money order payable to the Company; or

                    (ii) by delivery of shares of Common Stock owned by a
holder which has an aggregate fair Market Value on the date of exercise equal
to the aggregate Exercise Price; or

                    (iii) by delivery of irrevocable instructions to a broker
to sell shares of Common Stock to be issued upon exercise of the Warrants,
provided such shares of Common Stock are transferable pursuant to applicable
federal and state law and such broker agrees to immediately deliver the amount
of sales proceeds necessary to pay the aggregate Exercise price; or

                    (iv) by any combination of the above methods of payment.

             3. NOTICES TO WARRANT HOLDER. If, at any time prior to the
expiration or Exercise of the Warrants, any of the following events shall
occur:

                    (a) the Company shall declare any dividend payable in
securities upon its Shares or make any distribution (other than a cash dividend
payable out of earned surplus to the holders of its Shares; or



                                      -3-
   4

                    (b) the Company shall offer to the holders of its Shares
any additional shares of the Company or securities convertible into shares of
the Company or any right to subscribe therefor; or

                    (c) a dissolution, liquidation or winding-up of the Company
(other than in connection with a consolidation or merger) or a transfer of all
or substantially all of its assets shall be proposed; then in any one or more
of said events, the Company shall give to the holder of this Warrant, by
first-class mail, postage prepaid, at the address of such holder as shown on
the books of the Company, not less than twenty (20) days' prior notice of the
date on which:

                          (i) The books of the Company shall be closed or a
record taken for determination of the shareholders entitled to such dividend,
distribution or subscription rights; or

                          (ii) the books of the Company shall be closed or
record taken for determination of the shareholders entitled to vote on such
proposed dissolution, liquidation, winding-up or transfer.

             4. RESERVATION OF SHARES. The Company shall at all times reserve
for issuance such number of authorized and unissued Shares (or other securities
substituted therefor as hereinabove provided) as shall be sufficient for
exercise of the Warrants.

             5. BENEFITS OF THIS WARRANT. Nothing in this Warrant Certificate
shall be construed to confer upon any person other than the Company and the
holder of this Warrant Certificate any legal or equitable right, remedy or
claim under this Warrant Certificate and this Warrant Certificate shall be for
the sole and exclusive benefit of the Company and the holder of this Warrant
Certificate.

             6. UNREGISTERED SECURITIES. The Holder of this Warrant may not
exercise the Warrant if such exercise would be in violation of the Securities
Act of 1933, as amended, and the rules and regulations promulgated thereunder
(the "Act"). Any subsequent resale of the Shares may be made only upon proof by
the Holder to the satisfaction of counsel for the Company that the resale will
not result in a violation of the Act. The Holder shall make such
representations and supply such information as may, in the opinion of counsel
for the Company, be appropriate or advisable in view of the then existence or
nonexistence of an effective registration statement under the Act covering the
issuance of the Shares of the Company. The Holder hereby agrees that the
Company may place a stop order covering the transfer of any Shares issued
pursuant to the exercise of the Warrant with the Transfer Agent of such shares
and may place upon the certificates representing such shares a legend
indicating such restrictions.

             7.     DEMAND REGISTRATION.

                    (a) Request for Registration. Subject to the restrictions
contained in this Agreement, if at any time following six months after the
closing the Company's initial public offering of its Common Stock or other
transaction or event that results in the Company becoming a public company, the
Company receives from Holders who own at least a majority of the Common Stock
underlying the Warrants (which for the purpose herein shall include, the
underlying common stock of Warrants not then exercised), the written request
that the Company effect the registration of each such Holder=s Common Stock
(either for exercise and/or resale of the underlying Common Stock at the
Holders= option), the Company shall promptly, but in any event within fifteen
(15) days thereafter: (i) give written notice of the proposed registration to
all other Holders; and (ii) as soon as practicable, but in any event within
ninety (90) days after receipt of the request of the Holders, effect such
registration of the Common Stock of such requesting Holders, together with all
or such portion of the Common Stock of any other Holders who have given written
notice to the Company within twenty (20) days after receiving such written
notice from the Company pursuant to clause (i) above. Such obligation of the
Company shall include, without limitation, the execution of an undertaking to
file post-effective amendments and to effect appropriate registrations or
qualifications under a reasonable number of blue sky or other state securities
laws. The Company may request, subject to the Holders= approval, to delay the
effectiveness of such registration of the Holders (which shall toll the running
of the ninety (90) day period above) after delivery of the demand, except that
any such delay shall automatically extend the Expiration Period equal to the
period of the agreed upon registration deferral. If the registration of the
Common Stock of the Holders is not effected within ninety (90) days after the
demand, without limitation as to any other remedies that the Holders may have.
The Expiration Period shall be extended for a period equal to the delay beyond
ninety (90) days. The Holders making the registration request may withdraw the
request during such delay, in which event such Holder shall not be deemed to
have made the request.

   5


                    (b) Underwriting. If the Holders demand registration
pursuant to this Section 7 and the Holders intend to use an underwriter to
distribute the Common Stock covered by such request, they shall so advise the
Company in such request and the Company shall include such information in its
written notice to the other Holders. In such event, the right of any Holder to
registration pursuant to this Section shall be conditioned upon such Holder's
participation in such underwriting and the inclusion of all or part of such
Holder's Common Stock in the underwriting. The Company shall enter into an
underwriting agreement with an underwriter selected by the Holders, subject to
the approval of the Company of the content thereof, which shall not be
unreasonably withheld. In no event shall the Company be responsible for any
expenses of such underwriters or their attorney's fees (except with respect to
Blue Sky compliance), other than reasonably accountable travel and distribution
expenses. The underwriting agreement may contain reasonable provisions
regarding indemnification and contribution from the Company.

                    (c) One Demand Registration. The Company shall be obligated
to prepare, file and cause to become effective only one registration statement
pursuant to this Section 7 and to pay the costs and expenses associated with
such registration. Any Holders who own Common Stock, who do not participate in
a registration effected in accordance with this Section 7 shall not have any
further right to demand registration of such Holder's Common Stock.

             8. PIGGY-BACK REGISTRATION RIGHTS. If the Company shall at any
time file a new registration statement under the Securities Act relating to
shares of its Common Stock (other than on Forms S-4 or S-8), then it shall give
thirty days' prior written notice of its intention to do so to the Holder and,
if requested in writing by the Holder hereof not more than twenty days after
his receipt of such notice, the Company shall include in said registration
statement the shares issuable and if desired by the Holders, the resale
thereof, or theretofore issued upon exercise of the Warrant as the Holder
hereof shall request; provided, however, that if there is an underwriter
selected by the Company for such offering and sale, and it advises that, in its
professional opinion the number of shares of Common Stock proposed to be sold
by the Company and the holder of the Warrant is greater than the number of
shares of Common Stock which it believes may be sold, then the number of shares
of Common Stock to be sold shall first be allocated to the Company and any
balance thereafter shall be allocated to the Holder. If the Company includes
the Shares in such registration statement, and if the Company shall so request,
the Holder shall agree in writing not to sell any other shares of Common Stock
owned by the Holder for a period specified by the underwriter, but not
exceeding 180 days from the effective date of such registration statement or
such shorter period as may be applicable to officers and directors of the
Company, if the underwriter of the shares then being registered so requests.
The Company shall bear all costs and expenses of the registration statement
(and all amendments and supplements thereto) relating to the registration of
the Shares, including printing, legal and accounting expenses, and SEC filing
fees, expenses and transfer agency fees, but the Company shall have no
obligation to pay or otherwise bear (i) any portion of the fees or
disbursements of any counsel which any Holder may retain in connection with the
registration of the shares, (ii) any portion of the underwriter's commission,
discounts and expenses attributable to such shares being offered and sold by
the Warrant Holder or (iii) any applicable stock transfer taxes. Prior to the
effective date of any registration statement filed hereunder, the Company and
the persons requesting the registration will execute an agreement providing for
indemnification of each other in form satisfactory to the Company.

             9. LOSS OR DESTRUCTION OF WARRANT CERTIFICATE. If this Warrant
Certificate shall be surrendered mutilated to the Company, or if the Company
shall have received evidence to its satisfaction of its destruction, loss or
theft, and there be delivered to the Company such security or indemnity as may
be reasonably required by it to hold it harmless, then the Company shall
execute and deliver in lieu of this Warrant Certificate, or in substitution for
the mutilated Warrant Certificate (upon surrender of such Warrant Certificate)
a new Warrant Certificate.

             10. TRANSFERABILITY. Subject to compliance with applicable Federal
and State securities laws, this Warrant is transferable in whole or in part by
the Holder hereof. Upon such transfer, the Holder shall provide to the Company
an opinion of counsel satisfactory to the Company to the effect that such
transfer is in compliance with Federal and State securities laws.

             11. APPLICABLE LAW. This Warrant Certificate is issued under, and
shall for all purposes be governed by, and construed in accordance with the
laws of the State of Florida. This Warrant Certificate is binding upon the
Company and its successors and assigns.
