                                WARRANT AGREEMENT

Centex Securities Incorporated
7863 Girard Avenue, Suite 302
La Jolla, California  92037

Ladies and Gentlemen:

         Retrac Medical, Inc. (the "Company") confirms its agreement with you
with respect to the sale by the Company, and the purchase by you, of a common
stock purchase warrant (hereinafter referred to as the "Warrant or the
"Warrants", as the case may be) entitling the holders(s) to purchase up to
312,500 Units ("Units"), each Unit consisting of one (1) share of the Company's
$.01 par value common stock ("Common Stock") and one (1) Common Stock Purchase
Warrant and, except as expressly provided herein, otherwise being identical to
the Units to be sold by you pursuant to the Underwriting Agreement referred to
below.

         You and the Company have entered into an underwriting agreement, dated
_______________________, 2001, (the "Underwriting Agreement") with respect to
your sale on behalf of the Company of up to 3,125,000 Units, as more fully
described in the Underwriting Agreement. In consideration for your purchase of
the Units, the Company has agreed to sell to you the Warrant in accordance with
the terms and conditions of this Agreement. For purposes of this Agreement,
unless otherwise defined herein, the capitalized terms used in this Agreement
shall have the meanings given to such terms in the Underwriting Agreement.

                                    SECTION 1

                  SALE AND DELIVERY OF WARRANT; FORM OF WARRANT

         (a) The Company agrees to sell to you, and you agree to purchase from
the Company, the Warrant for the purchase price of $100.

         (b) Payment of the purchase price for, and delivery of the certificate
for, the Warrant to be purchased by you shall be made at the offices of Centex
Securities Incorporated at the address appearing above, or at such other place
as shall be determined by you by check payable to the order of the Company,
against delivery to you of the certificate for the Warrant to be purchased by
you.

<PAGE>

         (c) A Warrant shall be represented by a certificate (the "Warrant
Certificate" or the "Warrant Certificates", as the case may be) which shall be
substantially in the form set forth in Exhibit A hereto. The Warrant Certificate
shall be executed on behalf of the Company by its Chairman or Vice Chairman of
the Board of Directors or by its President or a Vice President and by its
Treasurer or an Assistant Treasurer or by its Secretary or an Assistant
Secretary; provided, however, that where such certificate is signed by a warrant
agent acting on behalf of the Company or a registrar other than the Company or
an employee of the Company, the signature of any such officer of the Company may
be a facsimile. In case any officer or officers who shall have signed, or whose
facsimile signature or signature shall have been used on, any such certificate
or certificates should cease to be such officer or officers of the Company,
whether because of death, resignation or otherwise, before such certificate or
certificates shall have been delivered by the Company, such certificate or
certificates may nevertheless be adopted by the Company and be issued and
delivered as though the person or persons who signed such certificate or
certificates, or whose facsimile signature or signatures shall have been used
thereon, had not ceased to be such officer or officers of the Company, and any
such delivery shall be regarded as an adoption by the Company of such
certificate or certificates.

                                    SECTION 2

                         TRANSFER OF EXCHANGE OF WARRANT

         (a) The Warrants shall be numbered and shall be registered in a warrant
register as they are issued. The Company shall be entitled to treat the
registered owner of any Warrant (the "Warrantholder") as the owner in fact
thereof for all purposes and shall not be bound to recognize any equitable or
other claim to or interest in such Warrant on the part of any other person, and
shall not be liable for any registration of transfer of Warrants which are
registered or to be registered in the name of a fiduciary or the nominee of a
fiduciary unless made with the actual knowledge that a fiduciary or nominee is
committing a breach of trust in requesting such registration of transfer, or
with such knowledge of such facts that its participation therein amounts to
gross negligence or bad faith.

         (b) The Warrant or Warrants may not be sold, transferred, assigned or
hypothecated, except to (i) one or more persons, each of whom on the date of
sales, transfer, assignment or hypothecation is an employee or officer and a
shareholder or partner of a Warrantholder; (ii) any successor to a Warrantholder
in merger or consolidation; (iii) a purchaser of all or substantially all of the
assets of a Warrantholder; and (iv) a person or persons who receive such Warrant
pursuant to the operation of law.

         (c) A Warrant shall be transferable only on the books of the Company,
maintained at its principal office or at the principal office of its warrant
agent, if any, upon delivery of the Warrant Certificate duly endorsed by the
Warrantholder or by his duly authorized attorney or representative, or
accompanied by proper evidence of succession, assignment, or authority to
transfer. In all cases of transfer by an attorney, the original power of
attorney, duly approved, or an official copy thereof, duly certified, shall be
deposited and remain with the Company of the warrant agent, if any. In case of
transfer by executors, administrators, guardians or other legal representatives,
duly authenticated evidence of their authority shall be produced, and may be
required to be deposited and remain with the Company or the warrant agent, if
any, in its discretion. Upon any registration of transfer, the Company or
warrant agent, if any, shall deliver a new Warrant Certificate or Certificates
to the persons entitled thereto.

                                      -2-
<PAGE>

         (d) Each Warrant Certificate may be exchanged for another certificate
or certificates entitling the Warrantholder thereof to purchase a like aggregate
number of Units as the certificate or certificates surrendered then entitle such
Warrantholder to purchase. Any Warrantholder desiring to exchange a Warrant
Certificate or certificates shall make such request in writing delivered to the
Company or the warrant agent, if any, and shall surrender, properly endorsed,
the certificate or certificates to be so exchanged. Thereupon, the Company or
warrant agent, if any, shall deliver to the Warrantholder a new Warrant
Certificate or Certificates, as the case may be as so requested.

                                    SECTION 3

                     TERMS OF WARRANTS; EXERCISE OF WARRANTS

         (a) Subject to the terms of this Agreement, each Warrantholder shall
have the right, which may be exercised commencing at 9:00 a.m. New York time on
_______________, 2002___1 and ending at 5:00 p.m. New York time
on________________, 2006,2 or if ________________, 2006 is a day on which
banking institutions are authorized to close, then on the next succeeding day
which shall not be such a day (the "Termination Date"), to purchase from the
Company the number of Units which the Warrantholder may at that time be entitled
to purchase on exercise of such Warrant or Warrants.

         (b) A Warrant shall be exercised by surrender to the Company, at its
principal office or at the principal office of the warrant agent, if any, of the
certificate or certificates evidencing the Warrant to be exercised, together
with the form of election to purchase on the reverse thereof duly filled in and
signed, and upon payment to the Company or to the warrant agent, if any, for the
Account of the Company of the Exercise Price (as defined in accordance with the
provisions of Section 8 hereof) for the number of Units in respect of which such
Warrant is then exercised. Payment of the aggregate Exercise Price shall be made
in cash or by check.

         (c) Subject to Section 4 hereof, upon such surrender of a Warrant
Certificate or Certificates and payment of the Exercise Price as aforesaid, the
Company shall issue and cause to be delivered with all reasonable dispatch to or
upon the written order of the Warrantholder exercising such Warrant and in such
name or names as such Warrantholder may designate, a certificate or certificates
for the number of Units so purchased upon the exercise of such Warrant, together
with cash, as provided in Section 7 hereof, in respect of any fractional Units
otherwise issuable upon such surrender. Such certificate or certificates 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 Units as of the date
of receipt by the Company or the warrant agent, if any, of such Warrant
Certificate or Certificates and payment of the Exercise Price, as aforesaid;
provided, however, that if at the date of surrender of such warrant certificate
or Certificates and payment of such Exercise Price, the transfer books of the
securities underlying the Units or other class of stock purchasable upon the
exercise of such Warrant shall be closed, the certificate or certificates for
the Units in respect of which such Warrant is then exercised shall be issuable
as of the date on which such books shall next be opened (whether before or after
the Termination Date) and until such date the Company shall be under no duty to
deliver any certificate for such Units; provided further, however, that the

<PAGE>

transfer books of record, unless otherwise required by law, shall not be closed
at any one time for a period longer than twenty days. The rights of purchase
represented by the Warrants shall be exercisable, at the election of the
Warrantholders thereof, either in full or from time to time in part and, in the
event that a Warrant Certificate is exercised in respect of less than all of the
Units purchasable on such exercise at any time prior to the Termination Date, a
new Warrant Certificate evidencing the remaining Units will be issued, and the
Company shall deliver, or the Warrant agent, if any, is hereby irrevocably
authorized to countersign and to deliver, the required new Warrant Certificate
or Certificates pursuant to the provisions of this Section and of Section 1
hereof and the Company whenever required by the warrant agent, if any, will
supply the warrant agent with Warrant Certificates duly executed on behalf of
the Company for such purpose.

                                    SECTION 4

                                PAYMENT OF TAXES

         The Company will pay all documentary stamp taxes, if any, attributable
to the initial issuance of the Units 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
the Warrant Certificates or the certificates for the Units in a name other than
that of the registered Warrantholder in respect of which such Units are issued.

                                    SECTION 5

                    MUTILATED OR MISSING WARRANT CERTIFICATES

         In case any Warrant Certificate shall be mutilated, lost, stolen, or
destroyed, the Company shall, at the request of the holder of such certificate,
issue and deliver, or the warrant agent, if any, shall countersign and deliver,
in exchange and substitution for and upon cancellation of the mutilated
certificate or certificates, or in lieu of and substitution for the certificate
or certificates lost, stolen, or destroyed, a new Warrant Certificate or
certificates of like tenor and representing an equivalent right or interest; but
only upon receipt of evidence satisfactory to the Company and the warrant agent,
if any, of such loss, theft, or destruction of such Warrant certificate or
Certificates and indemnity, if requested, also satisfactory to the Company and
the warrant agent, if any. An applicant for such a substitute Warrant
Certificate or Certificates shall also comply with such other reasonable
regulations and pay such other reasonable charges as the Company or the warrant
agent, if any, may prescribe.

                                    SECTION 6

                     RESERVATION OF SHARES OF WARRANT STOCK

         There has been reserved, and the Company shall at all times keep
reserved so long as any of the Warrants remain outstanding, out of its
authorized Common Stock a number of shares of Common Stock sufficient to provide
for the exercise of the rights of purchase represented by the outstanding
Warrants. The transfer agent for the Common Stock and every subsequent transfer
agent for any shares of the Company's capital stock issuable upon the exercise
of any of the rights or purchase aforesaid will be irrevocably authorized and

                                      -4-
<PAGE>

directed at all times to reserve such number of authorized shares as shall be
requisite for such purpose. The Company will keep a copy of this Agreement on
file with the transfer agent for the Common Stock and with every subsequent
transfer agent for any shares of the Company's capital stock issuable upon the
exercise of the rights of purchase represented by the Warrants. The warrant
agent, if any, is hereby irrevocably authorized to requisition from time to time
from such transfer agent the stock certificates required to honor outstanding
Warrants upon exercise thereof in accordance with the terms of this Agreement.
The Company will supply such transfer agent with duly executed stock
certificates for such purpose and will provide or otherwise make available any
cash which may be payable as provided in Section 7 hereof. All Warrant
Certificates surrendered in exercise of the rights thereby evidenced shall be
cancelled by the Company or the warrant agent, if any, who shall thereafter
deliver such certificates to the Company.

                                    SECTION 7

                                FRACTIONAL SHARES

         No fractional shares or scrip representing fractional shares shall be
issued upon the exercise of the Warrants. With respect to any fraction of a
share called for upon the exercise of any Warrant, the Company shall pay to the
Warrantholder an amount in cash equal to such fraction multiplied by the current
market value of such fractional share, determined as follows:

         (1) If the Common Stock is listed in a national securities exchange or
admitted to unlisted trading privileges on such exchange, the current value
shall be the last reported sale price of the Common Stock on such exchange on
the 1st business day prior to the date of exercise of the Warrant or if no such
sale is made on such day, the average closing bid and asked prices for such day
on such exchange; or

         (2) If the Common Stock is not so listed or admitted to unlisted
trading privileges, the current value shall be the mean of the last reported bid
and asked prices reported by the National Association of Securities Dealers
Quotation System ("NASDAQ") (or if not so quoted on NASDAQ, as quoted on the
NASDAQ "Bulletin Board" or by the National Quotation Bureau, Inc., as the case
may be) on the last business day prior to the date of the exercise of the
Warrant; or

         (3) If the Common Stock is not so listed or admitted to unlisted
trading privileges and bid and asked prices are not so reported, the current
value shall be an amount not less than book value, determined in such reasonable
manner as may be prescribed by the board of directors of the Company, such
determination to be final and binding on the Warrantholder.

                                      -5-

                                    SECTION 8

                    EXERCISE PRICE; ANTI-DILUTION PROVISIONS

         (a) EXERCISE PRICE. The price at which Units shall be purchasable upon
exercise of the Warrants shall be $9.60 per Unit (the "Exercise Price"), subject
to adjustment as provided in subsection (b) of this Section.

         (b) ADJUSTMENT OF EXERCISE PRICE IN THE EVENT OF STOCK DIVIDENDS, STOCK
SPLITS, AND REVERSE STOCK SPLITS. Anything in this Section to the contrary
notwithstanding, in case the Company shall at any time issue Common Stock by way
of dividend or other distribution on any stock of the Company or effect a stock
split or reverse stock split of the outstanding shares of Common Stock, the
Exercise Price shall be proportionately decreased in the case of such issuance
(on the day following the date fixed for determining shareholders entitled to
receive such dividend or other distribution) or decreased in the case of such
stock split or increased in the case of such reverse stock split (on the date
that such stock split, or reverse stock split shall become effective) by
multiplying the Exercise Price in effect immediately prior to the stock
dividend, stock split or reverse stock split by a fraction, the numerator of
which is the number of shares of Common Stock outstanding immediately prior to
such stock dividend, stock split, or reverse stock split, and the denominator of
which is the number of shares of Common Stock outstanding immediately after such
stock dividend, stock split or reverse stock split.

         (c) NO ADJUSTMENT FOR SMALL AMOUNTS. Anything in this Section to the
contrary notwithstanding, the Company shall not be required to give effect to
any adjustment in the Exercise Price unless and until the net effect of one or
more adjustments, determined as above provided, shall have required a change of
the Exercise Price by at least one cent, but when the cumulative net effect of
more than one adjustment so determined shall be to change the actual Exercise
Price by at least one cent, such change in the Exercise Price shall thereupon be
given effect.

         (d) NUMBER OF SHARES ADJUSTED. Upon any adjustment of the Exercise
Price, the Warrantholder shall thereafter (until another such adjustment) be
entitled to purchase, at the new Exercise Price, the number of Units, calculated
to the nearest full share, obtained by multiplying the number of Units initially
issuable upon exercise of any of the Warrant by the Exercise Price in effect on
the date hereof and dividing the product so obtained by the new Exercise Price.

         (e) COMMON STOCK DEFINED. Whenever reference is made in this Section to
the issue or sale of shares of Common Stock, the term "Common Stock" shall mean
the Common Stock of the Company of the class authorized as of the date hereof
and any other class of stock ranking on a parity with such Common Stock.
However, subject to the provisions of Section 10 hereof, shares issuable upon
exercise of the Warrants shall include only shares of the class designated by
the Company as Common Stock as of the date hereof.

         (f) STATEMENT ON WARRANTS. Irrespective of any adjustments in the
Exercise Price or the number or kind of shares purchasable upon the exercise of
the Warrants, the Warrant Certificates theretofore or thereafter issued may
continue to express the same price and number and kind of shares as are stated
in the Warrants initially issuable pursuant to this Agreement.

                              OFFICER'S CERTIFICATE

         Whenever the Exercise Price shall be adjusted as required by the
provisions of Section 8 hereof, the Company shall forthwith file in the custody
of its Secretary or an Assistant Secretary at its principal office, and with its
warrant agent, if any, an officer's certificate showing the adjusted Exercise
Price determined as herein provided and setting forth in reasonable detail the
facts requiring such adjustment. Each such officer's certificate shall be made
available at all reasonable times for inspection by the Warrantholders and the
Company shall, forthwith after each such adjustment, deliver a copy of such
certificate to each of the Warrantholders. Such certificate shall be conclusive
as to the correctness of such adjustment.

                                   SECTION 10

                   RECLASSIFICATION, REORGANIZATION, OR MERGER

         In case of any reclassification, capital reorganization, or other
change of outstanding shares of Common Stock of the Company (other than a change
in par value, or from par value to no par value, or from no par value to par
value, or as a result of an issuance of Common Stock by way of dividend of other
distribution or of a stock split or reverse stock split), or in case of any
consolidation or merger of the Company with or into another corporation (other
than a merger with a subsidiary in which merger the Company is the continuing
corporation and which does not result in any reclassification, capital
reorganization, or other change of outstanding shares of Common Stock of the
class issuable upon exercise of the Warrant) or in case of any sale or
conveyance to another corporation of the property of the Company as an entirety
or substantially as an entirety, the Company shall cause effective provision to
be made so that the Warrantholders shall have the right thereafter, by
exercising their Warrants, to purchase the kind and amount of shares of stock
and other securities and property receivable upon such reclassification, capital
reorganization, or other change, consolidation, merger, sale, or conveyance. Any
such provision shall include provision for adjustments which shall be as nearly
equivalent as may be practicable to the adjustments provided for in this
Agreement. The foregoing provisions of this Section shall similarly apply to
successive reclassification, capital reorganizations, and changes of shares of
Common Stock and to successive consolidations, mergers, sales, and conveyance.
If additional shares of Common Stock shall be issued in exchange conversion,
substitution, or payment, in whole or in part, for or of a security of the
Company other than Common Stock, any such issue shall be treated as an issue of
Common Stock covered by the provisions of Section 8 hereof with the amount of
the consideration received upon the issue thereof being determined by the board
of directors of the Company, such determination to be final and binding on the
holder.

                            NOTICES TO WARRANTHOLDERS

         So long as any Warrant shall be outstanding and unexercised (a) if the
Company shall pay any dividend or make any distribution upon the Common Stock or

(b) if the Company shall offer to the holders of Common Stock for subscription
or purchase by them any shares of stock of any class or any other rights or (c)
if any capital reorganization of the Company, reclassification of the capital
stock of the Company, consolidation, or merger of the Company with or into
another corporation, sale, lease, or transfer of all or substantially all of the
property and assets of the Company to another corporation, sale, lease, or
transfer of all or substantially all of the property and assets of the Company
to another corporation, or voluntary or involuntary dissolution, liquidation, or
with windup of the Company shall be effected, then in any such case, the Company
shall cause to be delivered to the Warrantholders, as provided in Section 16
herein, at least ten days prior to the date specified in (i) or (ii) below, as
the case may be, a notice containing a brief description of the proposed action
and stating the date on which (i) a record is to be taken for the purpose of
such dividend, distribution, or rights, or (ii) such reclassification,
reorganization, consolidation, merger, conveyance, lease, dissolution,
liquidation, or winding up is to take place and the date, if any, as of which
the holders of Common Stock of record shall be entitled to exchange their shares
of Common Stock for securities or other property deliverable upon such
reclassification, reorganization, consolidation, merger, conveyance,
dissolution, liquidation, or winding up.

                                   SECTION 12

                               REGISTRATION RIGHTS

         (a) Upon written notice at any time after _____________, 20023 and on
or before the date that is four years thereafter from any Majority Holder (as
such term is defined in subsection (d) of this Section) that he or it
contemplates the transfer of all or any of his or its Warrant Stock under such
circumstances that a public offering, within the meaning of the Act, of the
Warrant Stock will be involved, the Company, as promptly as possible after the
receipt of such notice, shall file a post-effective amendment, a new
registration statement or, if available, a notification under Regulation A under
the Act, with respect to the offering and sale or other disposition of the
Warrant Stock with respect to which it shall have received such notice. Within
ten days after receiving any such notice, the Company shall give notice to the
other owners of the Warrants and/or shares of Warrant Stock (the "Owners")
advising them that the Company is proceeding with such post effective amendment,
registration statement or notification and offering to include therein the
Warrant Stock of such Owners. The Company shall not be obligated to any such
other Owner unless such other Owner shall accept such offer by notice in writing
to the Company within ten days thereafter. The Company agrees to use its best
efforts to cause the post-effective amendment, registration statement or
notification on Form 1-A to thereafter become effective. The Warrantholders may
utilize the post-effective amendment, registration statement, or notification
without exercising the Warrants.

         (b) In connection with any demand registration pursuant to subsection
(a), the Company shall:

                  (i) Supply to you or your designee, as representative of the
Owners intending to make a public distribution of their Warrant Stock (the
Warrantholder by his or its receipt of the Warrant Certificate thereby
acknowledging his appointment of either of your or your designee as his or its

representative for purposes of this Agreement) two executed copies of each
post-effective amendment, registration statement, or notification and as many
copies of the preliminary, final, and other prospectuses or offering circulars
which shall have been prepared in conformity with requirements of the Act and
the rules and regulations promulgated thereunder and such other documents as you
or its designee may request at their expense.

                  (ii) Cooperate in taking such action as may be necessary to
register or qualify the Warrant Stock under the securities acts or blue sky laws
of the jurisdictions in which the Shares sold pursuant to the Underwriting
Agreement were originally qualified and of such jurisdictions as you or your
designee shall reasonably request and the Company shall do any and all other
acts and things which may be necessary or advisable to enable the Owners to
consummate such proposed sale or other disposition of the Warrant Stock in any
such jurisdiction; provided, however, that in no event shall the Company be
obligated, in connection therewith to qualify to do business or to file a
general consent to service of process in any jurisdiction where it shall not
then be qualified.

                  (iii) Be allowed to suspend its obligations under subsection
(a) of this Section 12 if, in the case of an underwritten public offering of the
Company's securities proposed to be made by the Company, the managing
underwriter shall state in writing to the Owners that in its opinion a potential
demand registration pursuant to this Section 12 would materially adversely
affect the Company's public offering. In such an event, the Company may elect to
suspend its obligations under this Section 12 until such time as, in the opinion
of the managing underwriter, the Company's public offering would not be
materially adversely affected by any demand registration hereunder.

                  (iv) Keep effective for a period of 60 days after the initial
effectiveness thereof all such post-effective amendments, registration
statements, or notifications under the Act and cooperate in taking such action
as may be necessary to keep effective such other registrations and
qualifications, and do any and all other acts and things for such period as may
be necessary to permit the public sale or other disposition of such Warrant
Stock by such holders, including, but not limited to, reflecting in the
post-effective amendment, registration statement, or notification financial
statements which shall be prepared in accordance with Section 10(a)(3) of the
Act and any facts or events arising which, individually or in the aggregate,
represent a fundamental and/or material change in the information set forth in
the post-effective amendment, registration statement, or notification to enable
any Owner to exercise or transfer the Warrant Stock during said 60 day period.

         (c) The Company shall comply with the requirement of subsections (a)
and (b) of this Section at the expense of the Warrantholders. In no event shall
the Company be required to file a post-effective amendment, registration
statement, or notification pursuant to the requirements of subsection (a) more
than once.

         (d) The term "Majority Holder" as used in this Section shall include
any owner or combination of owners of Warrants and/or Warrant Stock, in any
combination, if the holding of the aggregate amount of:

                                      -9-
<PAGE>

                  (A)  the Warrants then held by him, it, or among them, plus

                  (B) the Warrants which he, it, or they would then be holding
if such Warrants had not been exercised would constitute a majority of the
Warrants originally issued.

         The provisions contained herein shall continue in effect regardless of
the exercise or surrender of any of the Warrants.

                                   SECTION 13

                                 INDEMNIFICATION

         (a) The Company agrees to indemnify and hold harmless each Owner, each
underwriter who may purchase from or sell for any such Owner and each person, if
any, who controls any such Owner or Underwriter within the meaning of Section 15
of the Act as follows:

                  (i) against any and all loss, liability, claim, damage, and
expense whatsoever arising out of any untrue statement or alleged untrue
statement of a material fact contained in a post-effective amendment,
registration statement, or notification (or any amendment thereto) filed
pursuant to Section 12 hereof, or the omission or alleged omission therefrom of
a material fact required to be stated therein or necessary to make the
statements therein not misleading or arising out of any untrue statement or
alleged untrue statement of a material fact contained in any preliminary
prospectus, prospectus, or offering circular (or any amendment or supplement
thereto), or the omission or alleged omission therefrom of a material fact
necessary in order to make the statements therein, in light of the circumstances
under which they were made, not misleading, unless such untrue statement or
omission or such alleged untrue statement or omission was made in reliance upon
and in conformity with written information furnished to the Company by any Owner
or underwriter expressly for use in the post-effective amendment, registration
statement, or notification (or any amendment thereto) or such preliminary
prospectus, prospectus, or offering circular (or any amendment or supplement
thereto);

                  (ii) against any and all loss, liability, claim, damage, and
expense whatsoever to the extent of the aggregate amount paid in settlement of
any litigation, or investigation or proceeding by any governmental agency or
body, commenced or threatened, or any claim whatsoever based upon any such
untrue statement or omission, or any such alleged untrue statement or omission,
if such settlement is effected with the prior written consent of the Company;
and

                  (iii) against any and all expense whatsoever (including the
fees and disbursements of counsel chosen by such Owner and underwriter)
reasonably incurred in investigating, preparing, or defending against any
litigation, or investigation or proceeding by any governmental agency or body,
commenced or threatened, or any claim whatsoever based upon any such untrue
statement or omission, or any such alleged untrue statement or omission, to the
extent that any such expense in not paid under (i) or (ii) above.

                                      -10-
<PAGE>

         (b) Each Owner who utilizes a post-effective amendment, registration
statement, or notification pursuant to Section 12 hereof severally agrees to
indemnify and hold harmless the Company, its directors, each of its officers who
signed the post-effective amendment, registration statement, or notification,
and each person, if any, who controls the Company within the meaning of Section
15 of the Act against any and all loss, liability, claim, damage, and expense
described in the indemnity contained in subsection (a) of this Section, but only
with respect to untrue statements or omissions, or allege untrue statements or
omissions, made in the post-effective amendment, registration statement, or
notification (or any amendment thereto) or any preliminary prospectus,
prospectus, or offering circular (or any amendment or supplement thereto) in
reliance upon and in conformity with written information furnished to the
Company by such Owner expressly for use in the post-effective amendment,
registration statement, or notification (or any amendment thereto) or such
preliminary prospectus, prospectus, or offering circular (or any amendment or
supplement thereto).

         (c) In no case shall the Company be liable under the indemnity
provisions of this Section 13 with respect to any preliminary prospectus to the
extent any such loss, liability, claim, damage or expense of such Owner or
underwriter results from the fact that such Owner or underwriter sold shares to
a person to whom there was not sent or given, at or prior to the time such
person was sent or given a written confirmation of sale, a copy of the
definitive prospectus if the Company had previously furnished copies thereof to
such Owner or underwriter and the untrue statement or omission of material fact
contained in such preliminary prospectus was corrected in the definitive
prospectus.

         (d) Each indemnified party shall give prompt notice to each
indemnifying party of any action commenced against it in respect of which
indemnifying party of any action commenced against it in respect of which
indemnity may be sought hereunder, but failure to so notify an indemnifying
party shall not relieve it from any liability which it may have otherwise than
on account of this indemnity agreement. An indemnifying party may participate at
its own expense in the defense of such action. In no event shall the
indemnifying parties be liable for the fees and expenses of more than one
counsel for all indemnified parties in connection with any one action or
separate but similar or related actions in the same jurisdiction arising out of
the same general allegations or circumstances.

                                   SECTION 14

               TRANSFER TO COMPLY WITH THE SECURITIES ACT OF 1933

         (a) Neither the Warrants nor the Warrant Stock nor any other security
issued or issuable upon exercise of the Warrants may be sold, transferred, or
otherwise disposed of except pursuant to an effective registration statement

                   WARRANT TO PURCHASE ________________ UNITS
            VOID AFTER 5:00 p.m. NEW YORK TIME, ON ____________, 2006

         This certifies that, for value received, _______________, the
registered holder hereof or assigns (the "Warrantholder") is entitled to
purchase from Retrac Medical, Inc., a Delaware, corporation, at any time after
9:00 a.m., New York Time, on ___________________, 2002, and before 5:00 p.m.,
New York Time, on _______________, 2006, at the purchase price of $9.60 (the
"Exercise Price"), the number of Units, of the Company set forth above. The
number of Units purchasable upon exercise of this Warrant and the Exercise Price
per share shall be subject to adjustment from time to time as set forth in the
Warrant Agreement referred to below.

         The Warrant may be exercised in whole or in part by presentation of
this Warrant Certificate with the Purchase Form on the reverse side hereof duly
executed and simultaneous payment of the Exercise Price (subject to adjustment)
at the principal office of the Company or the warrant agent, if any. Payment of
such price shall be made at the option of the Warrantholder by cashier's check,
wire transfer or similar cash equivalent.

         This Warrant evidences the right to purchase an aggregate of up to
__________ Units, of the Company and is issued under and in accordance with a
Warrant Agreement dated as of _______________, 2001 (the "Warrant Agreement"),
between the Company and the Warrantholder and is subject to the terms and
provisions contained in the Warrant Agreement, to all of which the Warrantholder
of this Warrant by acceptance hereof consents.

         Upon any partial exercise of the Warrant, there shall be signed and
issued to the Warrantholder hereof a new Warrant Certificate in respect to the
Units as to which this Warrant shall not have been exercised. This Warrant
Certificate may be exchanged at the office of the Company by surrender of this
Warrant Certificate properly endorsed for one or more new Warrant Certificates
to purchase the same aggregate number of shares represented by the Warrant
Certificate exchanged. No fractional shares will be issued upon the exercise of
rights to purchase hereunder, but the Company shall pay the cash value of any
fraction upon the exercise of one or more Warrants. This Warrant Certificate is
transferable at the office of the Company or the warrant agent, if any, in the
manner and subject to the limitations set forth in the Warrant Agreement.

         This Warrant does not entitle any Warrantholder hereof to any of the
rights of a stockholder of the Company.
