EXHIBIT 10.10

                            CLASS B WARRANT AGREEMENT

            CLASS B WARRANT AGREEMENT ("Agreement"), dated as of _____, 2005, by
and between Safetek International, Inc., a Delaware corporation (the "Company"),
and ________ ("Warrantholder"). Certain capitalized terms used herein are
defined in Section 14 hereof.

            In consideration of the mutual terms, conditions, representations,
warranties and agreements herein set forth, and for other good and valuable
consideration, the receipt and sufficiency of which is hereby acknowledged, the
parties hereto hereby agree as follows:

Section 1. Issuance of Warrants.

            The Company hereby issues and grants to Warrantholder ____ Class B
Warrants ("Warrants") to purchase one (1) share of common stock of the Company
(the "Common Stock") per each Warrant. Commencing immediately (the "Warrant
Commencement Date"), and terminating two years after the date hereof (the
"Warrant Expiration Date"), the holder shall have the right, subject to the
satisfaction of the conditions to exercise set forth in Section 7 of this
Agreement, to purchase one (1) share of Common Stock per each Warrant (the
shares of Common Stock issuable upon exercise of the Warrants being collectively
referred to herein as the "Warrant Shares") at an exercise price of $1.50 per
Warrant Share (the "Exercise Price"). The number of Warrant Shares issuable on
exercise of each Warrant and the Exercise Price are all subject to adjustment
pursuant to Section 8 of this Agreement. Notwithstanding, the Company may, in
its sole and absolute discretion, reduce the Exercise Price.

Section 2. Form of Warrant Certificates.

            Promptly after the execution and delivery of this Agreement by the
parties hereto, the Company shall cause to be executed and delivered to
Warrantholder one or more certificates evidencing the Warrants (the "Warrant
Certificates"). Each Warrant Certificate delivered hereunder shall be
substantially in the form set forth in Exhibit A attached hereto and may have
such letters, numbers or other identification marks and legends, summaries or
endorsements printed thereon as the Company may deem appropriate and that are
not inconsistent with the terms of this Agreement or as may be required by
applicable law, rule or regulation. Each Warrant Certificate shall be dated the
date of execution by the Company.

Section 3. Execution of Warrant Certificates.

            Each Warrant Certificate delivered hereunder shall be signed on
behalf of the Company by its Chief Executive Officer, President or a Vice
President, and by its Secretary or an Assistant Secretary. Each such signature
may be in the form of a facsimile thereof and may be imprinted or otherwise
reproduced on the Warrant Certificates.

            If any officer of the Company who signed any Warrant Certificate
ceases to be an officer of the Company before the Warrant Certificate so signed
shall have been delivered by the Company, such Warrant Certificate nevertheless
may be delivered as though such person had not ceased to be such officer of the
Company.

<PAGE>

Section 4. Registration.

            Warrant Certificates shall be issued in registered form only. The
Company will keep or cause to be kept books for registration of ownership and
transfer of each Warrant Certificate issued pursuant to this Agreement. Each
Warrant Certificate issued pursuant to this Agreement shall be numbered by the
Company and shall be registered by the Company in the name of the holder thereof
(initially the Warrantholder). The Company may deem and treat the registered
holder of any Warrant Certificate as the absolute owner thereof (notwithstanding
any notation of ownership or other writing thereon made by anyone) for the
purpose of any exercise thereof and for all other purposes, and the Company
shall not be affected by any notice to the contrary.

Section 5. No Transfers.

            A. Restrictions on Transfer. No Warrant may be sold, pledged,
hypothecated, assigned, conveyed, transferred or otherwise disposed of (each a
"transfer") unless (i) the transfer complies with all applicable securities laws
and (ii) the transferee agrees in writing to be bound by the terms of this
Agreement.

            B. Cancellation. Warrant Certificates surrendered for transfer or
exchange shall be canceled by the Company.

Section 6. Mutilated or Missing Warrant Certificates.

            If any Warrant Certificate is mutilated, lost, stolen or destroyed,
the Company shall issue, upon surrender and cancellation of any mutilated
Warrant Certificate, or in lieu of and substitution for any lost, stolen or
destroyed Warrant Certificate, a new Warrant Certificate of like tenor and
representing an equal number of Warrants. In the case of a lost, stolen or
destroyed Warrant Certificate, a new Warrant Certificate shall be issued by the
Company only upon the Company's receipt of reasonably satisfactory evidence of
such loss, theft or destruction and, if requested, an indemnity or bond
reasonably satisfactory to the Company.

Section 7. Exercise of Warrants.

            A. Exercise. Subject to the terms and conditions set forth in this
Section 7, Warrants may be exercised, in whole or in part (but not as to any
fractional part of a Warrant), at any time or from time to time on and after the
Warrant Commencement Date and on or prior to 5:00 p.m., Eastern time, on the
Warrant Expiration Date.

            In order to exercise any Warrant, Warrantholder shall deliver to the
Company at its office referred to in Section 15 the following: (i) a written
notice in the form of the Election to Purchase appearing at the end of the form
of Warrant Certificate attached as Exhibit A hereto of such Warrantholder's
election to exercise the Warrants, which notice shall specify the number of such
Warrantholder's Warrants being exercised; (ii) the Warrant Certificate or
Warrant Certificates evidencing the Warrants being exercised; and (iii) payment
of the aggregate Exercise Price.

            All rights of Warrantholder with respect to any Warrant that has not
been exercised, on or prior to 5:00 p.m., Eastern time, on the Warrant
Expiration Date shall immediately cease and such Warrants shall be automatically
cancelled and void.

            B. Payment of Exercise Price. Payment of the Exercise Price with
respect to Warrants being exercised hereunder shall be made by the payment to
the Company, in cash, by check or wire transfer, of an amount equal to the
Exercise Price multiplied by the number of Warrants then being exercised.

<PAGE>

            C. Payment of Taxes. The Company shall be responsible for paying any
and all issue, documentary, stamp or other taxes that may be payable in respect
of any issuance or delivery of Warrant Shares on exercise of a Warrant.

            D. Delivery of Warrant Shares. Upon receipt of the items referred to
in Section 7A, the Company shall, as promptly as practicable, execute and
deliver or cause to be executed and delivered, to or upon the written order of
Warrantholder, and in the name of Warrantholder or Warrantholder's designee, a
stock certificate or stock certificates representing the number of Warrant
Shares to be issued on exercise of the Warrant(s). If the Warrant Shares shall
in accordance with the terms thereof have become automatically convertible into
shares of the Company's Common Stock prior to the time a Warrant is exercised,
the Company shall in lieu of issuing shares of Common Stock, issue to the
Warrantholder or its designee on exercise of such Warrant, a stock certificate
or stock certificates representing the number of shares of Common Stock into
which the Warrant Shares issuable on exercise of such Warrant are convertible.
The certificates issued to Warrantholder or its designee shall bear any
restrictive legend required under applicable law, rule or regulation. The stock
certificate or certificates so delivered shall be registered in the name of
Warrantholder or such other name as shall be designated in said notice. A
Warrant shall be deemed to have been exercised and such stock certificate or
stock certificates shall be deemed to have been issued, and such holder or any
other Person so designated to be named therein shall be deemed to have become a
holder of record of such shares for all purposes, as of the date that such
notice, together with payment of the aggregate Exercise Price and the Warrant
Certificate or Warrant Certificates evidencing the Warrants to be exercised, is
received by the Company as aforesaid. If the Warrants evidenced by any Warrant
Certificate are exercised in part, the Company shall, at the time of delivery of
the stock certificates, deliver to the holder thereof a new Warrant Certificate
evidencing the Warrants that were not exercised or surrendered, which shall in
all respects (other than as to the number of Warrants evidenced thereby) be
identical to the Warrant Certificate being exercised. Any Warrant Certificates
surrendered upon exercise of Warrants shall be canceled by the Company.

Section 8. Adjustment of Number of Warrant Shares Issuable Upon Exercise of a
Warrant and Adjustment of Exercise Price.

            A. Adjustment for Stock Splits, Stock Dividends, Recapitalizations.
The number of Warrant Shares issuable upon exercise of each Warrant and the
Exercise Price shall each be proportionately adjusted to reflect any stock
dividend, stock split, reverse stock split, recapitalization or the like
affecting the number of outstanding shares of Common Stock that occurs after the
date hereof.

            B. Adjustments for Reorganization, Consolidation, Merger. If after
the date hereof, the Company (or any other entity, the stock or other securities
of which are at the time receivable on the exercise of the Warrants),
consolidates with or merges into another entity or conveys all or substantially
all of its assets to another entity, then, in each such case, Warrantholder,
upon any permitted exercise of a Warrant (as provided in Section 7), at any time
after the consummation of such reorganization, consolidation, merger or
conveyance, shall be entitled to receive, in lieu of the stock or other
securities and property receivable upon the exercise of the Warrant prior to
such consummation, the stock or other securities or property to which such
Warrantholder would have been entitled upon the consummation of such
reorganization, consolidation, merger or conveyance if such Warrantholder had
exercised the Warrant immediately prior thereto, all subject to further
adjustment as provided in this Section 8. The successor or purchasing entity in
any such reorganization, consolidation, merger or conveyance (if other than the
Company) shall duly execute and deliver to Warrantholder a written
acknowledgment of such entity's obligations under the Warrants and this
Agreement.

            C. Notice of Certain Events.

<PAGE>

            Upon the occurrence of any event resulting in an adjustment in the
number of Warrant Shares (or other stock or securities or property) receivable
upon the exercise of the Warrants or the Exercise Price, the Company shall
promptly thereafter (i) compute such adjustment in accordance with the terms of
the Warrants, (ii) prepare a certificate setting forth such adjustment and
showing in detail the facts upon which such adjustment is based, and (iii) mail
copies of such certificate to Warrantholder.

            D. Adjustment to the Exercise Price.

            The Company has the right, in its sole and absolute discretion, to
reduce the Exercise Price. Upon any such determination, the Company shall
provide notice to the Warrantholder thereof.

Section 9. Reservation of Shares.

            The Company shall at all times reserve and keep available, free from
preemptive rights, out of the aggregate of its authorized but unissued Common
Stock, or its authorized and issued Common Stock held in its treasury, the
aggregate number of the Warrant Shares deliverable upon the exercise of all
outstanding Warrants, for the purpose of enabling it to satisfy any obligation
to issue the Warrant Shares upon the due and punctual exercise of the Warrants,
through 5:00 p.m., Eastern time, on the Warrant Expiration Date.

Section 10. No Impairment.

            The Company shall not, by amendment of its certificate of
incorporation or bylaws, or through reorganization, consolidation, merger,
dissolution, issuance or sale of securities, sale of assets or any other
voluntary action, willfully avoid or seek to avoid the observance or performance
of any of the terms of the Warrants or this Agreement, and shall at all times in
good faith assist in the carrying out of all such terms and in the taking of all
such actions as may be necessary or appropriate in order to protect the rights
of Warrantholder under the Warrants and this Agreement against wrongful
impairment. Without limiting the generality of the foregoing, the Company: (i)
shall not set or increase the par value of any Warrant Shares above the amount
payable therefor upon exercise, and (ii) shall take all actions that are
necessary or appropriate in order that the Company may validly and legally issue
fully paid and nonassessable Warrant Shares upon the exercise of the Warrants.

Section 11. Representations and Warranties of Warrantholder.

            Warrantholder represents and warrants to the Company that, on the
date hereof and on the date the Warrantholder exercises the Warrant pursuant to
the terms of this Agreement:

            (i) Warrantholder is an "accredited investor", as such term is
defined in Rule 501(a) of Regulation D promulgated under the Securities Act.

            (ii) Warrantholder understands that the Warrants and the Warrant
Shares have not been registered under the Securities Act and acknowledges that
the Warrants and the Warrant Shares must be held indefinitely unless they are
subsequently registered under the Securities Act or an exemption from such
registration becomes available.

            (iii) Warrantholder is acquiring the Warrants for Warrantholder's
own account for investment and not with a view to, or for sale in connection
with, any distribution thereof.

<PAGE>

            (iv) All the representations made by the Warrantholder on the date
hereof in the Subscription Agreement between the Company and the Warrantholder
shall be true and correct as of the date the Warrantholder exercises the
Warrant.

Section 12. No Rights or Liabilities as Stockholder.

            No holder, as such, of any Warrant Certificate shall be entitled to
vote, receive dividends or be deemed the holder of Common Stock which may at any
time be issuable on the exercise of the Warrants represented thereby for any
purpose whatever, nor shall anything contained herein or in any Warrant
Certificate be construed to confer upon the holder of any Warrant Certificate,
as such, any of the rights of a stockholder of the Company or any right to vote
for the election of directors or upon any matter submitted to stockholders at
any meeting thereof, or to give or withhold consent to any corporate action
(whether upon any recapitalization, issuance of stock, reclassification of
stock, change of par value or change of stock to no par value, consolidation,
merger, conveyance or otherwise), or to receive notice of meetings or other
actions affecting stockholders or to receive dividend or subscription rights, or
otherwise, until such Warrant Certificate shall have been exercised in
accordance with the provisions hereof and the receipt and collection of the
Exercise Price and any other amounts payable upon such exercise by the Company.
No provision hereof, in the absence of affirmative action by Warrantholder to
purchase Warrant Shares shall give rise to any liability of such holder for the
Exercise Price or as a stockholder of the Company, whether such liability is
asserted by the Company or by creditors of the Company.

Section 13. Fractional Interests.

            The Company shall not be required to issue fractional shares of
Common Stock upon exercise of the Warrants or to distribute certificates that
evidence fractional shares of Common Stock. If any fraction of a Warrant Share
would, except for the provisions of this Section 13, be issuable on the exercise
of a Warrant, the number of Warrant Shares to be issued by the Company shall be
rounded to the nearest whole number, with one-half or greater being rounded up.

                                   In the event that the second installment is
                                   not paid by the Investor within 12 months
                                   after the closing, and the Milestone was met,
                                   then all of the shares shall be forfeited
                                   back to the Company and canceled and the

                                   after the closing because the Milestone was
                                   not met, then 79.55% of the shares issued to
                                   investor shall be forfeited back to the
                                   Company and canceled and the funds invested

                                   after taking into account the forfeiture of
                                   the above mentioned shares and not taking
                                   into account any additional issuance of
                                   shares if any).

                                   second installment earlier than 12 months
                                   after the Closing, and even if the Milestone
