     THIS WARRANT CERTIFIES THAT, for value received, ________________________,
or registered assigns ("Warrantholder") is the registered owner of the above
indicated number of Warrants entitling the Warrantholder, commencing upon the
Exercise Date, as defined in paragraph 1 of this Certificate, but before 5:00
o'clock p.m., Mountain Standard Time, on the _______ day of _______________,
2003 ("Expiration Date") but not thereafter, to subscribe for, purchase and
receive one (1) fully paid and non-assessable share of Common Stock, $.004 par
value (the "Common Stock") of Cell Robotics International, Inc., a Colorado
corporation (the "Company"), at a purchase price of _________ dollars ($______)
per share of Common Stock ("Exercise Price") upon presentation and surrender  of
this Warrant and upon payment of the Exercise Price for such of the shares of
Common Stock of the Company, at any time after the Exercise Date, but only
subject to the conditions set forth herein.  The Exercise Price, the number of
shares purchasable upon exercise of each Warrant, and the Expiration Date are
subject to adjustments described herein.  The Warrantholders may exercise all or
any number of the Warrants represented hereby.  Upon exercise of this Warrant,
the form of election hereinafter provided for must be duly executed and the
instructions for registration of the Common Stock acquired by such exercise must
be completed.  If the rights represented hereby shall not be exercised at or
before the Expiration Date, this Warrant shall become and be void without
further force or effect, and all rights represented hereby shall cease and
expire.

     1.   TERM OF WARRANT.  The Warrants evidenced by this Warrant Certificate
may be exercised in whole or in part at any time commencing upon the date of
issuance (the "Exercise Date"), and ending at 5:00 o'clock p.m. Mountain Time on
the _______ day of _______________, 2003 ("Expiration Date"); provided, however,
that the Company may extend the Exercise Period of this Warrant by giving notice
of such extension.

     2.   NOTICE OF EXTENDED EXPIRATION DATE.  The Company may extend the
Expiration Date for the exercise of this Warrant at any time by giving thirty
(30) days' written notice thereof to the Warrantholder.  If this Warrant is not
exercised on or before the extended Expiration Date, it shall become wholly
void.

     3.   ADJUSTMENTS OF EXERCISE PRICE AND SHARES.  In the event the Common
Stock issuable upon exercise of this Warrant shall be changed into the same or
different number of shares of any class or classes of stock, whether by capital
reorganization, reclassification or otherwise, or in the event the Company shall
at any time issue Common Stock by way of dividend or other distribution on any
stock of the Company, or subdivide or combine the outstanding shares of Common
Stock, then in each such event the Holder of this Warrant shall have the right
thereafter to exercise such Warrant and receive the kind and amount of shares of
stock and other securities and property receivable upon such reorganization,
reclassification or other change by holders of the number of shares of Common
Stock into which such Warrant might have been exercised immediately prior to
such reorganization, reclassification or change.  In the case of any such
reorganization, reclassification or change, the Exercise Price shall also be
appropriately adjusted so as to maintain the aggregate Exercise Price.  Further,
in case of any consolidation or merger of the Company with or into another
corporation in which





consolidation or merger the Company is not the continuing corporation, 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 Warrantholder shall have the right
thereafter, by exercising this Warrant, to purchase the kind and amount of
shares of stock and other securities and property receivable upon such
consolidation, merger, sale or conveyance by holders of the number of shares of
Common Stock into which such Warrant might have been exercised immediately prior
to such consolidation, merger, sale or conveyance, which provision shall provide
for adjustments which shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Warrant.  The foregoing provisions shall
similarly apply to successive reclassifications, capital reorganizations and
changes of shares of Common Stock and to successive consolidations, mergers,
sales or conveyances.  Notwithstanding the foregoing, no adjustment of the
Exercise Price shall be made as a result of or in connection with (1) the
issuance of Common Stock of the Company pursuant to options, warrants and share
purchase agreements now in effect or hereafter outstanding or created, (2) the
establishment of option plans of the Company, the modification, renewal or
extension of any plan now in effect or hereafter created, or the issuance of
Common Stock upon exercise of any options pursuant to such plans, (3) the
issuance of Common Stock in connection with an acquisition, consolidation or
merger of any type in which the Company is the continuing corporation, or (4)
the issuance of Common Stock in consideration of such cash, property or service
as may be approved by the Board of Directors of the Company and permitted by
applicable law.

     4.   ADJUSTMENT TO PURCHASE PRICE.  The Company may, in its sole
discretion, lower the purchase price at any time, or from time-to-time.  When
any adjustment is made in the purchase price, the Company shall cause a copy of
such statement to be mailed to the Warrantholder, as of a date within ten (10)
days after the date when the purchase price has been adjusted.

     5.   MANNER OF EXERCISE.  The Warrantholder of the Warrants evidenced by
this Warrant Certificate may exercise all or any whole number of such Warrants
during the Exercise Period in the manner stated herein.  This Warrant
Certificate, together with the purchase form provided herein duly executed by
the Warrantholder or by the Warrantholder's duly authorized attorney, plus
payment of the exercise price in the manner set forth in paragraph 6 below,
shall be surrendered to the Company.  If upon exercise of any Warrants evidenced
by this Warrant Certificate the number of Warrants exercised shall be less than
the total number of Warrants so evidenced, there shall be issued to the
Warrantholder a new Warrant Certificate evidencing the number of Warrants not so
exercised.

     6.   MANNER OF PAYMENT.  The exercise price of each Warrant shall be paid
in cash at the time the Warrant is exercised.

     7.   REDEMPTION.  The Company shall have the right to redeem any or all
outstanding and unexercised Warrants evidenced by this Certificate at a
redemption price of $0.25 per Warrant upon thirty (30) days' written notice in
the event (i) a Registration Statement registering for sale under the Securities
Act of 1933, as amended (the "Act"), the shares of the Company's Common Stock
issuable upon exercise of the Warrant, has been filed with the Securities and
Exchange Commission and is in effect on the date of written notice and the
redemption date contained therein, (ii) there has been developed and exists on
the date of written notice a public trading market for the Company's Common
Stock and such shares are listed for quotation on the NASDAQ Stock Market or OTC
Electronic Bulletin Board, and (iii) the public trading price of the Company's
Common Stock has equalled or exceeded $10.00 per share for ten (10) or more
consecutive trading days.  On each occasion that the Company elects to exercise
its rights of redemption, the Company must mail such written notice within ten
(10) days following the satisfaction of all of the foregoing conditions.  The
holders of the Warrants called for redemption shall have the right to exercise
the Warrants evidenced hereby until the close of business on the date next
preceding the date fixed for redemption.  On or after the date fixed for
redemption, the holder hereof shall have no rights with respect to this Warrant
except the right to receive $0.25 per Warrant upon surrender of this
Certificate.

     8.   RESERVATION OF COMMON STOCK.  The Company agrees that the number of
shares of Common Stock sufficient to provide for the exercise of the Warrant
upon the basis herein set forth will at all times during the term of this
Warrant be reserved for the exercise thereof.

     9.   ISSUANCE OF COMMON STOCK UPON EXERCISE.  The Company, at its expense,
shall cause to be issued, within ten (10) days after exercise of this Warrant, a
certificate or certificates in the name requested by the Warrantholder of the
number of shares of Common Stock to which the Warrantholder is entitled upon
such exercise.  All shares of Common Stock or other securities delivered upon
the exercise of the Warrants shall be validly issued, fully paid and
non-assessable.

     10.  NO RIGHT AS STOCKHOLDER.  The Warrantholder is not, by virtue of
ownership of the Warrant, entitled to any rights whatsoever of a stockholder of
the Company.

     11.  ASSIGNMENT.  This Warrant is freely assignable by the Warrantholder
hereof, subject to (i) restrictions on transfer imposed by or on account of
federal and state securities laws and (ii) restrictions on transfer imposed by
or on account of a certain Subscription Agreement between the Company and the
initial holder hereof, a copy of which can be inspected at the principal offices
of the Company.
