                          COMMON STOCK PURCHASE WARRANT

            1. Issuance. In consideration of good and valuable consideration,
the receipt of which is hereby acknowledged by U.S. MedSys Corp., a Colorado
corporation (the "Company"), ________________________________________, or
registered assigns (the "Holder") is hereby granted the right to purchase at any
time commencing on the date hereof and until 5:00 P.M., E.S.T., on March __,
2008 (the "Expiration Date"), _________________________________ (________) fully
paid and nonassessable shares of the Company's Common Stock, no par value per
share (the "Common Stock") at an initial exercise price per share of $1.50 (the
"Exercise Price"), subject to further adjustment as set forth in Section 6
hereof.

            2. Exercise of Warrants. This Warrant is exercisable in whole or in
part at the Exercise Price per share of Common Stock payable hereunder, payable
in cash or by certified or official bank check. Upon surrender of this Warrant
with the annexed Notice of Exercise Form duly executed, together with payment of
the Exercise Price for the shares of Common Stock purchased, the Holder shall be
entitled to receive a certificate or certificates for the shares of Common Stock
so purchased.

            3. Reservation of Shares. The Company hereby agrees to reserve for
issuance upon exercise of this Warrant such number of shares of its Common Stock
as shall be required for issuance upon exercise of this Warrant (the "Warrant
Shares").

            4. Mutilation or Loss of Warrant. Upon receipt by the Company of
evidence satisfactory to it of the loss, theft, destruction or mutilation of
this Warrant, and (in the case of loss, theft or destruction) receipt of
reasonably satisfactory indemnification (which shall not include the posting of
any bond by the Holder), and (in the case of mutilation) upon surrender and
cancellation of this Warrant, the Company will execute and deliver a new Warrant
of like tenor and date and any such lost, stolen, destroyed or mutilated Warrant
shall thereupon become void.

            5. Rights of the Holder. FORM OF The Holder shall not, by virtue
hereof, be entitled to any rights of a stockholder in the Company, either at law
or equity, and the rights of the Holder are limited to those expressed in this
Warrant and are not enforceable against the Company except to the extent set
forth herein.

            6. Protection Against Dilution

                  6.1 Adjustment Mechanism. If an adjustment of the Exercise
Price is required pursuant to this Section 6, the Holder shall be entitled to
purchase such number of additional shares of Common Stock as will cause (i) the
total number of shares of Common Stock the Holder is entitled to purchase
pursuant to this Warrant, multiplied by (ii) the adjusted purchase price per
share, to equal (iii)

                                       1

                                     FORM OF

the dollar amount of the total number of shares of Common Stock the Holder is
entitled to purchase before adjustment multiplied by the total purchase price
before adjustment.

                  6.2 Capital Adjustments. In case of any stock split or reverse
stock split, stock dividend, reclassification of the Common Stock,
recapitalization, merger or consolidation, or like capital adjustment affecting
the Common Stock of the Company, the provisions of this Section 6 shall be
applied as if such capital adjustment event had occurred immediately prior to
the date of this Warrant and the original purchase price had been fairly
allocated to the stock resulting from such capital adjustment; and in other
respects the provisions of this Section shall be applied in a fair, equitable
and reasonable manner so as to give effect, as nearly as my be, to the purposes
hereof. A rights offering to stockholders shall be deemed a stock dividend to
the extent of the bargain purchase element of the rights.

                  6.3 Merger, Sale of Assets, Etc. If at any time while this
Warrant, or any portion hereof, is outstanding and unexpired there shall be (i)
a reorganization (other than a combination, reclassification, exchange or
subdivision of shares otherwise provided for herein), (ii) a merger or
consolidation of the Company with or into another corporation or other entity
including a merger or consolidation in which the Company is the surviving entity
but the shares of the Company's capital stock outstanding immediately prior to
the merger are converted by virtue of the merger into other property, whether in
the form of securities, cash, or otherwise, or (iii) a sale or transfer of the
Company's properties and assets as, or substantially as, an entirety to any
other person, then as a part of such reorganization, merger, consolidation, sale
or transfer lawful provision shall be made so that the holder of this Warrant
shall thereafter be entitled to receive upon exercise of this Warrant, during
the period specified herein and payment of the Exercise Price then in effect,
the number of shares of stock or other securities or property resulting from
such reorganization, merger, consolidation, sale or transfer that a holder of
the shares deliverable upon exercise of this Warrant would have been entitled to
receive in such reorganization, consolidation, merger, sale or transfer if this
Warrant had been exercised immediately before such reorganization, merger,
consolidation, sale or transfer, all subject to further adjustment as provided
in this Section 6. The foregoing provisions of this Section 6 shall similarly
apply to successive reorganization, consolidations, mergers, sales and transfers
and to the stock or securities of any other corporation or other entity that are
at the time receivable upon the exercise of this Warrant. If the consideration
deliverable to the Holder hereof in connection with any such transactions is in
a form other than cash or marketable securities, then the value of such
consideration shall be determined in good faith by the Company's Board of
Directors. In all events, appropriate adjustment (as determined in good faith by
the Company's Board of Directors) shall be made in the application of the
provisions of this Warrant with respect to the rights and interests of the
Holder after the transaction, to the end that the provisions of this Warrant
shall be applicable after that event, as near as reasonably may be, in relation
to any shares or other property deliverable after that event upon exercise of
this Warrant.

            7. Redemption by Company. In the event that the average closing bid
price of a share of the Company's Common Stock exceeds $3.00 for 20 consecutive
trading days, the Company has the right to redeem this Warrant for $.01 per
share of Common Stock purchasable hereunder, upon thirty days written notice.
The Holder shall have the right to exercise the Warrant in accordance with its
terms prior to the expiration of the thirty day period.

            8. Transfer to Comply with the Securities Act. This Warrant has not
been registered under the Securities Act and has been issued to the holder for
investment purposes and not with a view to the distribution of either the
Warrant or the Warrant Shares. Neither this Warrant nor any of the Warrant
Shares or any other security issued or issuable upon exercise of this Warrant
may be sold, transferred, pledged or hypothecated in the absence of an effective
registration statement under the Act relating to such security or an opinion of
counsel reasonably satisfactory to the Company that registration is not required
under the Securities Act. Each certificate for the Warrant, the Warrant Shares
