                                WARRANT AGREEMENT
                                -----------------

         THIS WARRANT AGREEMENT ("Agreement") is entered into as of , 2001 by
and between RETRAC MEDICAL, INC. a Delaware corporation ("Company"), and
COMPUTERSHARE TRUST COMPANY a ___________ corporation, as warrant agent
("Warrant Agent").

                                 R E C I T A L S
                                 ---------------

         A. The Company proposes to issue and sell up to 3,125,000 units
("Units") consisting of (i) one (1) share of the Company's $.01 par value common
stock, (such common stock and, where appropriate, such other securities or
assets purchasable upon the exercise of a Warrant (as defined below) as provided
for herein in the event of a reorganization, reclassification, consolidation,
merger or sale, collectively "Common Stock"), and (ii) one (1) common stock
purchase warrant ("Warrant"). The offering price for each Unit is Eight Dollars
($8.00). Each Warrant entitles the holder to purchase one (1) share of Common
Stock at an exercise price of Eight and 80/100 Dollars ($8.80), commencing upon
the date of the final Prospectus which is a part of the amended Registration
Statement filed with respect to such Units and declared effective pursuant to
the Securities Act of 1933, as amended, on , 2001 (the "Effective Date"), and
expires five (5) years after the Effective Date, unless such period is extended
by the Company.

         B. The Warrants included in the Units proposed to be sold by the
Company will be evidenced by a warrant certificate (such certificates and other
certificates issued pursuant hereto and evidencing Warrants ("Warrant
Certificate"), which will be detachable from the Common Stock included in the
Units, and will be immediately transferable separately from the Common Stock
included in the Units.

         C. The Company wishes to engage the Warrant Agent to act on behalf of
the Company, and the Warrant Agent is willing so to act, in connection with the
issuance, registration, registration of transfer and exchange of Warrant
Certificates and the exercise of Warrants.

                                A G R E E M E N T
                                -----------------

         NOW, THEREFORE, in consideration of the premises and the mutual
agreements herein set forth, the parties hereto agree as follows:

         SECTION 1. APPOINTMENT OF WARRANT AGENT. The Company hereby appoints
the Warrant Agent to act as agent for the Company in accordance with the
instructions hereinafter in this Agreement set forth, and the Warrant Agent
hereby accepts such appointment.

         SECTION 2. PURCHASE PRICE; FORM OF WARRANT CERTIFICATE. The Warrant
Certificates shall be in registered form only. The text of the Warrant
Certificates and of the form of election to exercise to be printed on the
reverse thereof shall be substantially as set forth in Exhibit A attached
hereto.


<PAGE>

         Each Unit issued pursuant to the Underwriting Agreement will have a
common stock certificate and a Warrant Certificate, each registered in the name
of the registered holder, evidencing Warrants at the rate of one (1) Warrant for
each one (1) shares of Common Stock included in each Unit, subject to adjustment
as provided in Section 11.

         Each Warrant shall entitle the holder thereof to purchase one (1) share
of Common Stock upon the exercise thereof. The purchase price payable upon
exercise of a Warrant ("Purchase Price") shall be, unless and until adjusted as
provided in Section 11, Eight and 80/100 Dollars ($8.80).

         The Purchase Price and the number of Warrants evidenced by each Warrant
Certificate are subject to adjustment upon the occurrence of certain events, as
hereinafter provided. Each Warrant may be exercised upon the Effective Date.

         Warrant Certificates may be exchanged and transferred separately from
Common Stock. The Warrant Certificates shall be executed on behalf of the
Company by the manual or facsimile signature of the present or any future
Chairman of the Board, President or Vice President of the Company, under its
corporate seal, affixed or in facsimile, attested by the manual or facsimile
signature of the present or any future Secretary or Assistant Secretary of the
Company.

         Warrant Certificates shall be dated the date of countersignature by the
Warrant Agent upon initial and subsequent issuances.

         Pending the preparation of definitive Warrant Certificates, the Company
may execute and the Warrant Agent shall countersign in lieu thereof temporary
Warrant Certificates, substantially in the form of the definitive Warrant
Certificates, but with such omissions, insertions and variations as may be
appropriate on temporary Certificates and as may be determined by the Board of
Directors of the Company ("Board of Directors"). Temporary Warrant Certificates
may be issued with such provisions with respect to exchanges of temporary
Warrant Certificates as may be determined by the Board of Directors and may
contain such references to provisions of the Warrant Agreement as may be
appropriate. Every temporary Warrant Certificate shall be executed by the
Company and be countersigned by the Warrant Agent upon the same conditions and
in substantially the same manner and with like effect as the definitive Warrant
Certificates. If temporary Warrant Certificates are issued, the Company shall
prepare and execute definitive Warrant Certificates without unnecessary delay,
and thereupon any and all temporary Warrant Certificates may be surrendered in
exchange therefor at the principal office of the Warrant Agent and the Warrant
Agent shall countersign and deliver in exchange for such temporary Warrant
Certificates definitive Warrant Certificates evidencing the number of Warrants
evidenced by the temporary Warrant Certificates so surrendered. Until so
exchanged, each temporary Warrant Certificate shall entitle the holder thereof
to the same rights and benefits as the holder of a definitive Warrant
Certificate.

         SECTION 3. REGISTRATION AND COUNTERSIGNATURE. The Warrant Agent shall
maintain books for the registration and registration of transfer of Warrant
Certificates. Upon the initial issuance of the Units of Common Stock and
Warrants, the Warrant Agent shall issue and register the Warrant Certificates in
the names of the respective registered holders and upon subsequent issuances of
Units of Common Stock and Warrants, the Warrant Certificates for such Warrants
shall be registered in the names of the respective registered holders. The
Warrant Certificates shall be countersigned by the Warrant Agent and shall not
be valid for any purpose unless so countersigned. Warrant Certificates shall be
so countersigned, however, by the Warrant Agent and be delivered by the Warrant
Agent, notwithstanding that the persons whose manual or facsimile signatures
appear thereon as proper officers of the Company shall have ceased to be such
officers at the time of such countersignature or delivery. Upon issuance of any
Warrant Certificate, the Company will present the same, or cause the same to be
presented, to the Warrant Agent for countersignature of such Warrant
Certificate.

<PAGE>

         Prior to due presentment for registration of transfer of the Warrant
Certificates, the Company and the Warrant Agent may deem and treat the
registered holder thereof as the absolute owner of the Warrant Certificates
(notwithstanding any notation of ownership or other writing thereon made by
anyone other than the Company or the Warrant Agent), for the purpose of any
exercise thereof and for all other purposes, and neither the Company nor the
Warrant Agent shall be affected by any notice to the contrary.

         SECTION 4. REGISTRATION OF TRANSFERS AND EXCHANGES. The Warrant Agent
shall from time to time register the transfer of any outstanding Warrant
Certificates upon the books to be maintained by the Warrant Agent for that
purpose, upon surrender thereof accompanied (if so required by the Company or
the Warrant Agent) by a written instrument or instruments of transfer in form
satisfactory to the Company and the Warrant Agent, duly executed by the
registered holder or by a duly authorized attorney and the transfer fee, payable
by the holder, of _____ Dollars __________ ($_____) for each transfer. Upon any
such registration of transfer, a new Warrant Certificate shall be issued to the
transferee and the surrendered Warrant Certificate shall be cancelled by the
Warrant Agent. Warrant Certificates so cancelled shall be delivered by the
Warrant Agent to the Company from time to time or otherwise disposed of by the
Warrant Agent in a manner satisfactory to the Company. Warrant Certificates are
detachable and they may be exchanged at the option of the holder thereof, when
surrendered at the principal office in ____________________, of the Warrant
Agent, for another Warrant Certificate or other Warrant Certificates of like
tenor and representing in the aggregate the number of Warrants evidenced by the
Warrant Certificate or Warrant Certificates so surrendered. The Warrant Agent
shall countersign and deliver, in accordance with the provisions of this Section
and of Section 3, the new Warrant Certificates required pursuant to the
provisions of this Section, and the Company, whenever required by the Warrant
Agent, will supply the Warrant Agent with Warrant Certificates duly executed on
behalf of the Company for such purpose.

         SECTION 5. DURATION AND EXERCISE OF WARRANTS.

                  A. The Warrants will expire at the close of business on ,
2006, unless extended by the Company, in which event the Warrants shall expire
upon the expiration of the period the Warrants are so extended, at which time
all rights evidenced by the Warrant Certificates shall cease and the Warrants
shall become void.

                  B. Subject to the provisions of this Agreement, the holder of
one (1) Warrant shall have the right to purchase from the Company (and the
Company shall issue and sell to such holder of one (1) Warrant) one fully paid
and non-assessable share of Common Stock at an initial Purchase Price set forth
in Section 2 hereof (subject to adjustment as provided in Section 11) upon
surrender of the Warrant Certificate evidencing such Warrant to the Company at
the principal office of the Warrant Agent in _______________, with the form of
election to purchase on the reverse thereof duly filled in and signed, and upon
payment of the Purchase Price in lawful money of the United States of America to
the Warrant Agent for the account of the Company. Except as set forth in Section
11 of this Agreement, no adjustment shall be made for any dividends on any share
of Common Stock issuable on the exercise of a Warrant.
<PAGE>

         The Purchase Price payable upon exercise of Warrants shall be paid in
cash or by certified check or bank draft.

         Subject to Sections 7 and 12, upon such surrender of a Warrant
Certificate, and payment of the Purchase Price, the Company shall issue and
cause to be registered, countersigned and delivered to or upon the written order
of the registered holder of such Warrant Certificate and in such name or names
as such registered holder may designate, a certificate for one (1) share of
Common Stock for each Warrant then being exercised. Such certificate shall be
deemed to have been issued and any person so designated to be named therein
shall be deemed to have become a holder of record of such share or shares of
Common Stock, as of the date of the surrender of such Warrant Certificates and
payment of the Purchase Price; provided, however, that if, at the date of
surrender of such Warrant Certificates and payment of such Purchase Price, the
transfer books for the Common Stock shall be closed, the certificate for such
share or shares of Common Stock shall be issuable as of the date on which such
books shall next be opened and until such date the Company shall be under no
duty to deliver any certificate for such share or shares; provided, further,
that such books, unless otherwise required by law, shall not be closed at any
one time for a period longer than 20 days. The Warrants evidenced by the Warrant
Certificates shall be exercisable immediately upon issuance, at the election of
the registered holders thereof, either as an entirety or from time to time for
only part of the number of Warrants evidenced by the Warrant Certificates. In
the event that less than all of the Warrants evidenced by a Warrant Certificate
surrendered upon the exercise of Warrants are exercised at any time prior to the
date of expiration of the Warrants, a new Warrant Certificate will be issued for
the remaining number of Warrants evidenced by the Warrant Certificate so
surrendered, and the Warrant Agent shall countersign and deliver the required
new Warrant Certificate pursuant to the provisions of this Section and of
Section 3 and the Company, whenever required by the Warrant Agent, will supply
the Warrant Agent with a Warrant Certificate duly executed on behalf of the
Company for such purpose.

         SECTION 6. CALL OF WARRANTS FOR REDEMPTION. The Company shall have the
right to call the Warrants for redemption, as a whole, or from time to time in
part substantially pro rata, at the price of one cent ($.01) per Warrant on
thirty (30) days' prior written notice if the Closing Price of the Common Stock
exceeds Fourteen Dollars ($14.00) over a period of 15 consecutive trading days
ending within 15 days of the notice of redemption. Should the Company call the
Warrants at a time when said Warrants are not exercisable, the Warrants shall
become immediately exercisable through the Redemption Date (as defined below).

         Notice of call shall be mailed by the Warrant Agent to the registered
holders of the Warrants by first-class mail, postage prepaid not less than
thirty (30) nor more than ninety (90) days prior to the date ("Redemption Date")
set by the Company's Board of Directors for redemption, to their last addresses
as they shall appear upon the Warrant register.

         The redemption price is subject to adjustment in the event of stock
splits on other similar events. All outstanding Warrants must be redeemed if any
are to be redeemed.

<PAGE>

         The redemption price payable after the call date upon surrender of the
Warrant Certificate evidencing the Warrants to the Company at the principal
office of the Warrant Agent in _______________, shall be paid in cash or by
certified check or bank draft. Warrant Certificates so called shall be delivered
by the Warrant Agent to the Company from time to time or otherwise disposed of
by the Warrant Agent in a manner satisfactory to the Company. Following the date
fixed for call and redemption, only those Warrants not so called shall be
exercisable.

         As used herein, the term "Closing Price" for each day shall be either
(i) the last reported sale price as officially reported on the principal
exchange on which the Common Stock is listed or the National Association of
Securities Dealers, Inc. Automated Quotation System ("NASDAQ") National Market
System, if so quoted, or (ii) if not so listed or quoted, the closing price as
reported on NASDAQ. Notice to the registered holders of the Warrant Certificates
hereunder, stating the time (which shall be 5:00 P.M. New York time) and the
Redemption Date by which such holders must submit their Warrant Certificates to
the Warrant Agent shall be given by the Company, or the Warrant Agent at the
Company's request, by first-class, postage prepaid mail to the registered
holders of outstanding Warrant Certificates.

         In case the Company shall exercise its right to redeem it shall give
notice to the registered holders of the outstanding Warrants by mailing to such
registered holders a notice of redemption, first class, postage prepaid, not
later than the thirtieth (30) day before the date fixed for redemption, at their
last address as shall appear on the records of the Warrant Agent. Any notice
mailed in the manner provided herein shall be conclusively presumed to have been
duly given whether or not the registered holder receives such notice.

         The notice of redemption shall specify the redemption price, the date
fixed for redemption, the place where the redeemed Warrant Certificates shall be
delivered, and that the right to exercise the Warrant shall terminate at 5:00
P.M. (New York time) on the business day immediately preceding the date fixed
for redemption.

         The date fixed for redemption of the Warrants shall be the Redemption
Date. No failure to mail such notice nor any defect therein or in the mailing
thereof shall affect the validity of the proceedings for such redemption except
as to a holder (a) to whom notice was not mailed or (b) whose name was
defective. An affidavit of the Warrant Agent or of the Secretary or an Assistant
Secretary of the Company that notice of redemption has been mailed shall, in the
absence of fraud, be prima facie evidence of the facts stated therein.

         Any right to exercise a Warrant shall terminate at 5:00 P.M. (New York
time) on the business day immediately preceding the Redemption Date. On and
after the Redemption Date, Holders of the Warrants shall have no further rights
except to receive, upon surrender of the Warrant, the Redemption Price.

         From and after the Redemption Date, the Company shall, at the place
specified in the notice of redemption, upon presentation and surrender to the
Company by or on behalf of the Registered Holder thereof of one or more Warrants
to be redeemed, deliver or cause to be delivered to or upon the written order of
such Holder a sum in cash equal to the redemption price of each such Warrant.
From and after the date fixed for redemption and upon the deposit or setting
aside by the Company of a sum sufficient to redeem all the Warrants called for
redemption, such Warrants shall expire and become void and all rights hereunder
and under the Warrant Certificates, except the right to receive payment of the
redemption price, shall cease.
<PAGE>

         SECTION 7. PAYMENT OF TAXES. The Company will pay all documentary stamp
taxes, if any, attributable to the initial issuance of shares of Common Stock
upon the exercise of Warrants; 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 certificates for shares of Common Stock
in any name other than that of the registered holder of a Warrant Certificate
surrendered upon the exercise of a Warrant.

         SECTION 8. MUTILATED OR MISSING WARRANT CERTIFICATES. In case any of
the Warrant Certificates shall be mutilated, lost, stolen or destroyed, the
Company may in its discretion issue and the Warrant Agent may countersign and
deliver in exchange and substitution for and upon cancellation of the mutilated
Warrant Certificate, or in lieu of and substitution for the Warrant Certificate
mutilated, lost, stolen or destroyed, a new Warrant Certificate of like tenor
and evidencing the number of Warrants evidenced by the Warrant Certificate so
mutilated, lost, stolen or destroyed, but only upon receipt of evidence
satisfactory to the Company and the Warrant Agent of such loss, theft or
destruction of such Warrant Certificate and indemnity, if requested, also
satisfactory to them. Applicants for such substitute Warrant Certificate shall
also comply with such other reasonable regulations and pay such other reasonable
charges as the Company or the Warrant Agent may prescribe.

         SECTION 9. RESERVATION OF COMMON STOCK, ETC. There have been reserved,
and the Company shall at all times keep reserved, out of the authorized and
unissued shares of Common Stock, a number of shares sufficient to provide for
the exercise of the Warrants, and the Transfer Agent for the Common Stock is
hereby irrevocably authorized and directed at all times to reserve such number
of authorized and unissued shares as shall be requisite for such purpose. The
Company will keep a copy of this Agreement on file with such Transfer Agent. The
Warrant Agent is hereby irrevocably authorized to requisition from time to time
from such Transfer Agent stock certificates issuable upon exercise of
outstanding Warrants. The Company will supply such Transfer Agent with duly
executed stock certificates for such purpose. All Warrant Certificates
surrendered upon exercise of Warrants shall be cancelled by the Warrant Agent
and shall thereafter be delivered to the Company or otherwise disposed of in a
manner satisfactory to the Company. Unless all Warrants shall have been
exercised prior to the time of the expiration of the Warrants, the Warrant Agent
shall certify to the Company, as of the close of business on the date of such
expiration, the total aggregate amount of Warrants then outstanding, and
thereafter no shares of Common Stock shall be subject to reservation in respect
of such Warrants.

         SECTION 10. OBTAINING OF GOVERNMENTAL APPROVALS. The Company will from
time to time take all action which may be necessary to obtain and keep effective
any and all permits, consents and approvals of governmental agencies and
authorities which may be or become requisite in connection with the issuance,
sale, transfer and delivery of the Warrant Certificates to the initial Warrant
holders.

         SECTION 11. ADJUSTMENTS TO PURCHASE PRICE AND NUMBER OF WARRANTS. The
Purchase Price and the number of Warrants evidenced by any Warrant Certificate
shall be subject to adjustment from time to time as follows:
<PAGE>

                  (A) In case the shares of Common Stock at any time outstanding
shall be subdivided into a greater or combined into a lesser number of shares of
Common Stock or in case shares of Common Stock shall be issued as a stock
dividend, the Purchase Price shall be decreased or increased, as the case may
be, to an amount which shall bear the same relation to the Purchase Price in
effect immediately prior to such subdivision or combination or stock dividend as
the total number of shares of Common Stock outstanding immediately prior to such
subdivision or combination or stock dividend shall bear to the total number of
shares of Common Stock outstanding immediately after such subdivision or
combination or stock dividend.

                  (B) In case of any capital reorganization, or of any
reclassification of the Common Stock, of the Company or in case of the
consolidation of the Company with or the merger of the Company into any other
corporation (other than a consolidation or merger in which the Company is the
continuing corporation) or of the sale of the properties and assets of the
Company as, or substantially as, an entirety to any other corporation, each
Warrant shall after such capital reorganization, reclassification of Common
Stock, consolidation, merger or sale be exercisable, upon the terms and
conditions specified in this Agreement, for the number of shares of stock or
other securities or property of the Company, or of the corporation resulting
from such consolidation or surviving such merger or to which such sale shall be
made, as the case may be, to which the Common Stock issuable (at the time of
such capital reorganization, reclassification of Common Stock, consolidation,
merger or sale) upon exercise of such Warrant would have been entitled upon such
capital reorganization, reclassification of Common Stock, consolidation, merger
or sale if such exercise had taken place; and in any such case, if necessary,
the provisions set forth in this Section 11 with respect to the rights and
interests thereafter of the holders of the Warrants shall be appropriately
adjusted so as to be applicable, as nearly as may reasonably be, to any shares
of stock or other securities or property thereafter deliverable on the exercise
of the Warrants. The subdivision or combination of shares of Common Stock at any
time outstanding into a greater or lesser number of shares of Common Stock shall
not be deemed to be a reclassification of the Common Stock of the Company for
the purposes of this paragraph. The Company shall not effect any such
consolidation, merger or sale, unless prior to or simultaneously with the
consummation thereof the successor corporation (if other than the Company)
resulting from such consolidation or merger or the corporation purchasing such
assets shall assume by written instrument executed and delivered to the Warrant
Agent, the obligation to deliver to the holder of each Warrant such shares of
stock, securities or assets as, in accordance with the foregoing provisions,
such holders may be entitled to purchase and the other obligations under this
Agreement.

                  (C) In case after the date hereof, the Company shall declare a
dividend upon shares of Common Stock payable otherwise than out of retained
earnings or otherwise than in shares of Common Stock or in stock or obligations
directly or indirectly convertible into or exchangeable for Common Stock, the
holder of each Warrant shall, upon exercise of such Warrant in whole or in part,
be entitled to purchase, in addition to the number of shares of Common Stock
deliverable upon such exercise against payment of the Purchase Price therefor,
but without further consideration, the cash, stock or other securities or
property which the holder of such Warrant would have received as dividends
(otherwise than out of such retained earnings and otherwise than in shares of
Common Stock or in such convertible or exchangeable stock or obligations), if
continuously since the date of the Warrant Certificate evidencing such Warrant
such holder (i) had been the holder of record of the number of shares of Common
Stock deliverable upon such exercise and (ii) had retained all dividends in
stock or other securities (other than shares of Common Stock or such convertible
or exchangeable stock or obligations) paid or payable in respect of said number
of shares of Common Stock or in respect of any such stock or other securities so
paid or payable as such dividends. For purposes of this subparagraph (C), a
dividend payable otherwise than in cash shall be considered to be payable out of
retained earnings only to the extent that such retained earnings shall be
charged in an amount equal to the fair value of such dividend as determined by
the Board of Directors.
<PAGE>

                  (D) Anything in this Section 11 to the contrary
notwithstanding, the Company shall not be required, except as hereinafter in
this subparagraph (D) provided, to make any adjustment of the Purchase Price in
any case in which the amount by which such Purchase Price would be reduced in
accordance with the foregoing provisions of Section 11 would be less than one
cent ($.01) per share of Common Stock, but in such case any adjustment that
would otherwise be required then to be made will be carried forward and made at
the time of and together with the next subsequent adjustment which, together
with any and all such adjustments so carried forward, shall amount to one cent
($.01) or more per share of Common Stock. In the event of any subdivision or
combination of shares of Common Stock said amount of one cent ($.01) (as
theretofore decreased or increased by any previous subdivision or combination)
shall be proportionately decreased or increased.

                  (I) Upon each adjustment of the Purchase Price each Warrant
Certificate shall thereafter (until another such adjustment) evidence that
number of Warrants (calculated to the nearest hundredth) obtained by multiplying
the number of Warrants evidenced by such Warrant Certificate immediately prior
to such adjustment by the Purchase Price in effect immediately prior to such
adjustment and dividing the product so obtained by the Purchase Price in effect
after such adjustment.

                  (J) Whenever there is an adjustment in the Purchase Price as
provided herein, the Company shall promptly (1) file with the Warrant Agent a
certificate signed by the Chairman of the Board, President or a Vice President
of the Company and by the Treasurer or an Assistant Treasurer or the Secretary
or an Assistant Secretary of the Company, stating the Purchase Price as so
adjusted and showing in detail the facts requiring such adjustment and the
number of Warrants to be evidenced by outstanding Warrant Certificates as a
result of such adjustment and (2) cause a notice stating that such adjustment
has been effected and stating the Purchase Price then in effect and the number
of Warrants to be evidenced by outstanding Warrant Certificates as a result of
such adjustment to be sent by first-class mail, postage prepaid, to each
registered holder of a Warrant Certificate as a result of such adjustment to be
sent by first-class mail, postage prepaid, to each registered holder of a
Warrant Certificate at his address appearing on the Warrant register. The
Warrant Agent shall have no duty with respect to any such certificate (or its
contents) filed with it except to keep the same on file and available for
inspection by holders of Warrant Certificates during reasonable business hours.
The Warrant Agent shall not at any time be under any duty or responsibility to
any holder of a Warrant Certificate to determine whether any facts exist which
may require any adjustment of the Purchase Price or with respect to the nature
or extent of any such adjustment when made, or with respect to the method
employed in making any such adjustment.

                  (K) Each Warrant Certificate shall state the Purchase Price in
effect on the date of countersignature thereof by the Warrant Agent and shall
specify the number of Warrants evidenced by such Warrant Certificate as of such
date, in each case after giving effect to all adjustments, if any, theretofore
required to have been made pursuant to Section 11.

                  (L) The Company may retain M.R. Weiser & Co. LLP, or such
other firm of independent public accountants of recognized standing, which may
be the firm regularly retained by the Company, selected by the Board of
Directors to make any computation required under this Section, and a certificate
signed by such firm shall be conclusive evidence of the correctness of any
computation made under this Section.

         SECTION 12. FRACTIONAL WARRANTS. As provided in Section 2, each Warrant
upon initial issuance shall entitle the holder thereof to purchase no less than
one (1) share of Common Stock upon the exercise thereof, but the number of
Warrants evidenced by any Warrant Certificate shall be subject to adjustment,
pursuant to Section 11, upon the occurrence of certain events. In the event of
adjustment of the number of shares of Common Stock and the Purchase Price
pursuant to the provisions of Section 11, the Company shall not be required to
issue fractions of shares upon the exercise of any Warrant. In such an event,
the holder of a Warrant shall have the right to purchase a whole share of Common
Stock at the Purchase Price.

         SECTION 13. NOTICES TO WARRANT HOLDERS. Nothing contained in this
Agreement or in any of the Warrant Certificates shall be construed as conferring
upon the holders thereof the right to vote or to consent or to receive notice as
stockholders in respect of the meetings of stockholders or the election of
Directors of the Company or any other matter, or any rights whatsoever as
stockholders of the Company; provided, however, that in the event that:

                  (1) the Company shall take action to make any distribution
(other than cash dividends payable out of retained earnings) to the holders of
Common Stock;

                  (2) the Company shall take action to offer for subscription
pro rata to the holders of Common Stock any additional shares of stock of any
class or other rights or securities convertible into Common Stock;

                  (3) the Company shall take action to accomplish any capital
reorganization, or reclassification of the capital stock of the Company (other
than a change in par value, or a change from par value to no par value, or a
change from no par value to par value, or a subdivision or merger of the Company
into, or sale of all or substantially all of its assets to, another corporation;
or

                  (4) the Company shall take action looking to a voluntary or
involuntary dissolution, liquidation or winding up of the Company;

then, in any one or more of such cases, the Company shall (a) at least 10 days
prior to the date on which the books of the Company shall close or a record
shall be taken for such distribution or subscription rights or for determining
rights to vote in respect of any such reorganization, reclassification,
consolidation, merger, sale, dissolution, liquidation or winding up, cause
written notice thereof to be sent by first-class mail, postage prepaid, to each
registered holder of a Warrant Certificate at his address appearing on the
Warrant register, and (b) in the case of any such reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation or
winding up, cause at least 20 days' prior written notice of the date when the
same shall take place to be given to each registered holder of a Warrant
Certificate in the same manner. Such notice in accordance with the foregoing
clause (a) shall also specify, in the case of any such distribution or
subscription rights, the date on which the holders of Common Stock shall be
entitled thereto, and such notice in accordance with the foregoing clause (b)
shall also specify the date on which the holders of Common Stock shall be
entitled to exchange their Common Stock for securities or other property
deliverable upon such reorganization, reclassification, consolidation, merger,
sale, dissolution, liquidation or winding up, as the case may be.

         SECTION 14. DISPOSITION OF PROCEEDS ON EXERCISE OF WARRANTS, ETC.

                  A. Upon the exercise of each Warrant as provided in Section 5,
the Warrant Agent shall promptly deposit the Purchase Price payment in an escrow
account ("Escrow Account") to be established by the mutual agreement of the
Company and the Warrant Agent at a federally insured commercial bank. On a
weekly basis, there shall be remitted to the Company the amount of collected
funds on deposit in the Escrow Account, as determined by the Warrant Agent, net
of an amount equal to the Warrant Agent's reimbursable expenses. Upon
disbursement of the collected funds to the Company, the Warrant Agent shall
cause to be issued and delivered the share certificate(s) representing the
shares issuable with respect to such collected funds.

         Expenses incurred by the Warrant Agent for acting as warrant agent in
connection with each Warrant exercised, including those associated with the
issuance and delivery of share certificates, shall be paid by the Company and
shall be payable by disbursement from the Escrow Account prior to disbursement
to the Company of its portion of the collected funds relating to such exercised
Warrants.

         The Warrant Agent shall prepare and deliver to the Company on a weekly
basis at the time each disbursement is made from the Escrow Account a detailed
written accounting relating to the Warrants exercised, Warrant Agent expenses
reimbursed and the collected funds remitted to the Company from the Escrow
Account, which shall serve as an interim accounting. A final accounting will be
prepared and delivered to the Company by the Warrant Agent promptly following
expiration of the exercise period for the Warrants.

                  B. The Warrant Agent shall keep copies of this Agreement
available for inspection by holders of Warrants during normal business hours at
its principal office in _______________________.

         SECTION 15. MERGER OR CONSOLIDATION OR CHANGE OF NAME OF WARRANT AGENT.
Any corporation into which the Warrant Agent may be merged or with which it may
be consolidated, or any corporation resulting from any merger or consolidation
to which the Warrant Agent shall be a party, or any corporation succeeding to
the corporate trust business of the Warrant Agent, shall be the successor to the
Warrant Agent hereunder without the execution or filing of any paper or any
further act on the part of any of the parties hereto, provided that such
corporation would be eligible for appointment as a successor Warrant Agent under
the provisions of Section 17 of this Agreement. In case at the time such
successor to the Warrant Agent shall succeed to the agency created by this
Agreement, and in case at that time any of the Warrant Certificates shall have
been countersigned but not delivered, any such successor to the Warrant Agent
may adopt the countersignature of the predecessor Warrant Agent and deliver such
Warrant Certificates so countersigned; and in case at that time any of the
Warrant Certificates shall not have been countersigned, any successor to the
Warrant Agent may countersign such Warrant Certificates either in the name of
the predecessor Warrant Agent or in the name of the successor Warrant Agent; and
in all such cases such Warrant Certificates shall have the full force provided
in the Warrant Certificates and in this Agreement.
<PAGE>

         In case at any time the name of the Warrant Agent shall be changed and
at such time any of the Warrant Certificates shall have been countersigned but
not delivered, the Warrant Agent may adopt the countersignature under its prior
name and deliver Warrant Certificates so countersigned; and in case at that time
any of the Warrant Certificates shall not have been countersigned, the Warrant
Agent may countersign such Warrant Certificates either in its prior name or in
its changed name; and in all such cases such Warrant Certificates shall have the
full force provided in the Warrant Certificates and in this Agreement.

         SECTION 16. DUTIES OF WARRANT AGENT. The Warrant Agent undertakes the
duties and obligations imposed by this Agreement upon the following terms and
conditions, by all of which the Company and the holders of Warrants, by their
acceptance thereof, shall be bound:

                  A. The statements contained herein and in the Warrant
Certificates shall be taken as statements of the Company and the Warrant Agent
assumes no responsibility for the correctness of any of the same except such as
describe the Warrant Agent or action taken or to be taken by it. The Warrant
Agent assumes no responsibility with respect to the delivery of Warrant
Certificates except as herein otherwise provided.

                  B. The Warrant Agent shall not be responsible for any failure
of the Company to comply with any of the covenants contained in this Agreement
or in the Warrant Certificates to be complied with by the Company.

                  C. The Warrant Agent may execute and exercise any of the
rights or powers hereby vested in it or perform any duty hereunder either itself
or by or through its attorneys, agents or employees and the Warrant Agent shall
not be answerable or accountable for any act, default, neglect or misconduct of
any such attorneys, agents or employees or for any loss to the Company resulting
from such neglect or misconduct, provided reasonable care shall have been
exercised in the selection and continued employment thereof.

                  D. The Warrant Agent may consult at any time with counsel
satisfactory to it (who may be counsel for the Company) and the Warrant Agent
shall incur no liability or responsibility to the Company or to any holder of
any Warrant Certificate in respect of any action taken, suffered or omitted by
it hereunder in good faith and in accordance with the opinion or the advice of
such counsel, provided the Warrant Agent shall have exercised reasonable care in
the selection and continued employment of such counsel.

                  E. The Warrant Agent shall incur no liability or
responsibility to the Company or to any holder of any Warrant Certificate for
any action taken in reliance on any notice, resolution, waiver, consent, order,
certificate, or other paper, document or instrument believed by it to be genuine
and to have been signed, sent or presented by the proper party or parties.

                  F. The Company agrees to pay to the Warrant Agent reasonable
compensation for all services rendered by the Warrant Agent in the execution of
this Agreement, to reimburse the Warrant Agent for all expenses, taxes and
governmental charges and other charges of any kind and nature incurred by the
Warrant Agent in the execution of this Agreement and to indemnify the Warrant
Agent and save it harmless against any and all liabilities, including judgments,
costs and counsel fees, for anything done or omitted by the Warrant Agent in the
execution of this Agreement except as a result of the Warrant Agent's negligence
or bad faith.
<PAGE>

                  G. The Warrant Agent shall be under no obligation to institute
any action, suit or legal proceeding or to take any other action likely to
involve expense unless the Company or one or more registered holders of Warrant
Certificates shall furnish the Warrant Agent with reasonable security and
indemnity for any costs and expenses which may be incurred. All rights of action
under this Agreement or under any of the Warrants may be enforced by the Warrant
Agent without the possession of any of the Warrant Certificates or the
production thereof at any trial or other proceeding relative thereto, and any
such action, suit or proceeding instituted by the Warrant Agent shall be brought
in its name as Warrant Agent, and any recovery of judgment shall be for the
ratable benefit of the registered holders of the Warrants, as their respective
rights or interest may appear.

                  H. The Warrant Agent and any stockholder, director, officer or
employee of the Warrant Agent may buy, sell or deal in any of the Warrants or
other securities of the Company or become pecuniarily interested in any
transaction in which the Company may be interested, or contract with or lend
money to or otherwise act as fully and freely as though it were not Warrant
Agent under this Agreement. Nothing herein shall preclude the Warrant Agent from
acting in any other capacity for the Company or for any other legal entity.

                  I. The Warrant Agent shall act hereunder solely as agent, and
its duties shall be determined solely by the provisions hereof. The Warrant
Agent shall not be liable for anything which it may do or refrain from doing in
connection with this Agreement except for its own negligence or bad faith.

         SECTION 17. CHANGE OF WARRANT AGENT. The Warrant Agent may resign and
be discharged from its duties under this Agreement by giving to the Company
notice in writing, and to the holders of the Warrant Certificates notice in
writing and sent by first class mail, postage prepaid, to each registered holder
of a Warrant Certificate at his address appearing in the Warrant register,
specifying a date when such resignation shall take effect. If the Warrant Agent
shall resign or shall otherwise become incapable of acting, the Company shall
appoint a successor to the Warrant Agent. If the Company shall fail to make such
appointment within a period of 30 days after it has been notified in writing of
such resignation or incapacity by the resigning or incapacitated Warrant Agent
or by the registered holder of a Warrant Certificate (who shall, with such
notice, submit his Warrant Certificate for inspection by the Company, then the
registered holder of any Warrant may apply to any court of competent
jurisdiction for the appointment of a successor to the Warrant Agent. Any
successor warrant agent, whether appointed by the Company or by such a court,
shall be a bank or trust company, in good standing, incorporated under the laws
of the United States of America or of any State or Territory or of the District
of Columbia and having at the time of its appointment as warrant agent a
combined capital and surplus of at least One Million Dollars ($1,000,000). After
appointment the successor warrant agent shall be vested with the same powers,
rights, duties and responsibilities as if it had been originally named as
Warrant Agent without further act or deed; but the former Warrant Agent shall
deliver and transfer to the successor warrant agent any property at the time
held by it hereunder, and execute and deliver any further assurance, conveyance,
act or deed necessary for the purpose. Failure to give any notice provided for
in this Section, however, or any defect therein, shall not affect the legality
or validity of the resignation or removal of the Warrant Agent or the
appointment of the successor warrant agent, as the case may be.
<PAGE>

         SECTION 18. IDENTITY OF TRANSFER AGENT. Forthwith upon the appointment
after the date hereof of any Transfer Agent for the Common Stock or of any
subsequent Transfer Agent for shares of the Common Stock, the Company will file
with the Warrant Agent a statement setting forth the name and address of such
Transfer Agent.

         SECTION 19. NOTICES. Any notice pursuant to this Agreement to be given

Agent may from time to time supplement or amend this Agreement without the
approval of any holders of Warrant Certificates in order to cure any ambiguity
or to correct or supplement any provision contained herein which may be
defective or inconsistent with any other provision herein, or to make any other

form in all material respects with the requirements of said Act and the rules
and regulations of the Securities and Exchange Commission thereunder; or (ii) a

Statement is in effect the Company will, from time to time, furnish the Warrant
Agent with current Prospectuses meeting the requirements of said Act and all
rules and regulations thereunder in sufficient quantity to permit the Warrant
Agent to deliver a Prospectus to each holder of a Warrant upon exercise thereof.
The Company further agrees to pay all fees, costs and expenses in connection
with the preparation and delivery to the Warrant Agent of the foregoing opinions
and Prospectuses.

         SECTION 23. TERMINATION. This Agreement shall terminate at the close of
business on _____, 2006, unless the Warrants shall be extended by the Company,
in which event this Agreement shall terminate at the close of business on the
day such period expires, or such earlier date upon which all Warrants have been
exercised, except that the Warrant Agent shall account to the Company pursuant
to Section 14 for all cash held by it at the close of business on such date of
termination. The provisions of Section 16 shall survive such termination.

         SECTION 24. GOVERNING LAW. This Agreement and each Warrant Certificate
