surrender of this Warrant Agreement, with the attached Purchase Form duly
executed, at the principal office of the Company, or at such other place as the
Company may designate by notice to the Holder hereof, together with a certified
or bank cashiers check payable to the order of the Company in the amount of
the Exercise Price times the number of Shares being purchased (or in the case
of exercise pursuant to Section 1(c)(i) or (ii), as set forth in such
sections), the Company shall deliver to the Holder hereof, as promptly as
practicable and in any event within 10 days, certificates representing the
Shares being purchased. This Warrant may be exercised in whole or in part;

(b) This Warrant may be exercised at a price of $0.01 per share (the
Exercise Price) which is not subject to adjustment. The Warrant shall expire
upon the repayment of all amounts due pursuant to the Loan, including accrued
interest. (c) The Exercise Price shall be payable at the time of exercise. The
Exercise Price may be paid in cash (by cashiers check or wire transfer). 2. Exchange and Transfer of Warrant. At any time prior to the exercise hereof, upon presentation and surrender
to the Company, this Warrant (a) may be exchanged, alone or with other Warrants
of like tenor registered in the name of the Holder, for another Warrant or
other Warrants of like tenor in the name of such Holder exercisable for the
same aggregate number of Shares as the Warrant or Warrants surrendered, but (b)
may not be sold, transferred, hypothecated, or assigned, in whole or in part,
without the prior written consent of the Company. 3. Rights and Obligations of Warrant Holder. (a) The Holder of this Warrant Agreement shall not, by virtue hereof, be
entitled to any rights of a stockholder in the Company, either at law or in
equity; provided, however, that in the event that any certificate representing
the Shares is issued to the Holder hereof upon exercise of this Warrant, such
Holder shall, for all purposes, be deemed to have become the holder of record
of such Shares on the date on which this Warrant Agreement, together with a
duly executed Purchase Form, was surrendered and payment of the Exercise Price
was made, irrespective of the date of delivery of such Share certificate. The
rights of the Holder of this Warrant are limited to those expressed herein and
the Holder of this Warrant, by his acceptance hereof, consents to and agrees to
be bound by and to comply with all the provisions of this Warrant Agreement,
including, without limitation, all the obligations imposed upon the Holder
hereof by Sections 2 and 5 hereof. In addition, the Holder of this Warrant
Agreement, by accepting the same, agrees that the Company may deem and treat
the person in whose name this Warrant Agreement is registered on the books of
the Company maintained for such purposes as the absolute, true and lawful owner
for all purposes whatsoever, notwithstanding any notation of ownership or other
writing thereon, and the Company shall not be affected by any notice to the
contrary. (b) No Holder of this Warrant Agreement shall be entitled to vote or
receive dividends or to be deemed the holder of Shares for any purpose, nor
shall anything contained in this Warrant Agreement be construed to confer upon
any Holder of this Warrant Agreement any of the rights of a stockholder of the
Company or any right to vote, give or withhold consent to any action by the
Company, whether upon any recapitalization, issue of stock, reclassification of
stock, consolidation, merger, conveyance or otherwise, receive notice of
meetings or other action affecting stockholders (except for notices provided
for herein), receive dividends, subscription rights, or otherwise, until this
Warrant shall have been exercised and the Shares purchasable upon the exercise
thereof shall have become deliverable as provided herein; provided, however,
that any such exercise on any date when the stock transfer books of the Company
shall be closed shall constitute the person in whose name the certificate for
those Shares are to be issued as the record holder thereof for all purposes at
the opening of business on the next succeeding day on which such stock transfer
books are open, and the Warrant surrendered shall not be deemed to have been
exercised, in whole or in part as the case may be, until the next succeeding
day on which stock transfer books are open for the purpose of determining
entitlement to dividends on the Companys common stock. 4. Shares Underlying Warrant. The Company covenants and agrees that all Shares delivered upon exercise
of this Warrant shall, upon delivery and payment therefor, be duly and validly
authorized and issued, fully paid and non-assessable, and free 2

from all stamp taxes, liens and charges with respect to the purchase
thereof. 5. Representations and Warranties of Holder; Disposition of Warrant or
Shares. (a) The Holder acknowledges that it has had access to all material
information concerning the Company which it has requested. The Holder also
acknowledges that it has had the opportunity to, and has to its satisfaction,
questioned the officers of the Company with respect to this Warrant. The
Holder is purchasing the Warrant and any Common Stock issued upon exercise
thereof for investment for its own account only and not with a view to, or for
resale in connection with, any distribution thereof in violation of the Act
or State Acts. The Holder further represents that it understands that the
Warrant and Common Stock to be issued upon exercise thereof have not been
registered under the Act or State Acts by reason of specific exemptions
therefrom, which exemptions depend upon, among other things, the bona fide
nature of the Holders investment intent as expressed herein. The Holder is an
accredited investor as defined in Regulation D promulgated under the Act. (b) The Holder of this Warrant Agreement and any transferee hereof or of
the Shares issuable upon the exercise of the Warrant Agreement, by their
acceptance hereof, hereby understand and agree that the Warrant, and the Shares
issuable upon the exercise hereof, have not been registered under either the
Act or State Acts and shall not be sold, pledged, hypothecated, or otherwise
transferred (whether or not for consideration) except upon the issuance to the
Company of an opinion of counsel favorable to the Company or its counsel or
submission to the Company of such evidence as may be satisfactory to the
Company or its counsel, in each such case, to the effect that any such transfer
shall not be in violation of the Act or the State Acts. It shall be a
condition to the transfer of this Warrant that any transferee of this Warrant
deliver to the Company his written agreement to accept and be bound by all of
the terms and conditions of this Warrant Agreement. (c) The stock certificates of the Company that will evidence the shares of
Common Stock with respect to which this Warrant may be exercisable will be
imprinted with a conspicuous legend in substantially the following form: The securities represented by this certificate have not
been registered under either the Securities Act of 1933
(Act) or the securities laws of any state (State Acts).
Such securities shall not be sold, pledged, hypothecated, or
otherwise transferred (whether or not for consideration) at
any time whatsoever except upon registration or upon
delivery to the Company of an opinion of its counsel
satisfactory to the Company or its counsel that registration
is not required for such transfer or the submission of such
other evidence as may be satisfactory to the Company or its
counsel to the effect that any such transfer shall not be in
violation of the Act, State Acts or any rule or regulation
promulgated thereunder. (d) The Company has granted Holder registration rights to the shares
underlying this Warrant, as set forth in the Registration Rights Agreement
between the Company and the Holder dated August 19, 2004 (the Registration
Rights Agreement). 6. Adjustments. (a) Notwithstanding anything else herein, the number of Shares purchasable
upon the exercise of this Warrant shall be an amount equal to 100% of the then
outstanding principal balance under the Term Promissory Note dated August 19,
2004 delivered by Company to Zurich in the face amount of $189,298 which
evidences the Loan (the Note) plus any accrued but unpaid interest under the
Note, plus an amount equal to a reasonable projection for brokerage commissions
and related fees that Lender will incur upon the sale of the 3

Shares, divided by the greater of (i) the average closing price of the
Common Stock for the 10 days prior to the date Common Stock is issued upon
exercise of this Warrant minus $0.01, and (ii) $0.15. (b) In case the Company (i) consolidates with or merges into any other
entity and is not the continuing or surviving entity of such consolidation or
merger, or (ii) permits any other entity to consolidate with or merge into the
Company and the Company is the continuing or surviving Company but, in
connection with such consolidation or merger, the Common Stock is changed into
or exchanged for common stock or other securities of any other entity or cash
or any other assets, or (iii) transfers all or substantially all of its
properties and assets to any other entity, or (iv) effects a reorganization or
reclassification of the equity of the Company in such a way that holders of
Common Stock shall be entitled to receive stock, securities, cash or assets
with respect to or in exchange for Common Stock, then, and in each such case,
proper provision shall be made so that, upon the exercise of this Warrant at
any time after the consummation of such consolidation, merger, transfer,
reorganization or reclassification, the Holder shall be entitled to receive (at
the aggregate Exercise Price in effect for Common Stock issuable upon such
exercise of this Warrant immediately prior to such consummation), in lieu of
Common Stock issuable upon such exercise of this Warrant prior to such
consummation, the stock and other securities, cash and assets to which such
Holder would have been entitled upon such consummation if such Holder had so
exercised this Warrant immediately prior thereto. 7. Covenants of Holder. (a) Upon the repayment of all amounts due pursuant to the Loan, including
accrued interest, the Holder will return this Warrant and the Warrant shall be
cancelled. (b) Upon the exercise of this Warrant and any subsequent sale of the
Shares, the proceeds of any such sale shall be deemed to reduce amounts due
pursuant to the Note, including accrued interest. 8. Representations, Warranties and Certain Covenants of Company. (a) The execution, delivery and performance by the Company of this
Warrant, the Registration Rights Agreement, and the issuance of the shares of
Common Stock upon exercise of the Warrant, have been duly authorized by all
necessary corporate action. The Company has reserved 948,517 shares of Common
Stock for issuance pursuant to this Warrant. This Warrant and the Registration
Rights Agreement have been duly executed and delivered by the Company and each
constitute valid and binding obligations of the Company enforceable in
accordance with their respective terms, except (i) as limited by applicable
bankruptcy, insolvency, reorganization, moratorium and other laws of general
application affecting enforcement of creditors rights generally and (ii) as
limited by laws relating to the availability of specific performance,
injunctive relief or other equitable remedies. The execution, delivery and
performance of the transactions contemplated by this Warrant and compliance
with its provisions by the Company will not violate any provision of law and
will not conflict with or result in any breach of any of the terms, conditions
or provisions of, or constitute a default under, or require a consent or waiver
under, (x) the Companys Amended and Restated Certificate of Incorporation or
Restated Bylaws (each as amended to date) or (y) any indenture, lease,
agreement or other instrument to which the Company is a party or by which it or
any of its properties is bound, or any decree, judgment, order, statute, rule
or regulation applicable to the Company which conflict or breach would result
in a material adverse change in the business, operations or condition
(financial or otherwise) of the Company (a Material Adverse Effect). (b) The Company is a corporation organized under the laws of the state of
Delaware, has power and authority to own its properties and assets and to carry
on its business as it is now being conducted, and is duly qualified to do
business and is in good standing in each jurisdiction in which its ownership of
property or the conduct of its business requires such qualification, except for
jurisdictions in which such failure to be so qualified or to be in good
standing would not have a Material Adverse Effect. 4

(c) Exercise of the Warrant as contemplated hereby will transfer to the
Holder good, valid and marketable title to the Shares, free and clear of any
liens, claims or encumbrances, except as set forth in any legend which appears
on any certificate representing any of the Shares. (d) The issuance and delivery of the shares of Common Stock to be issued
upon exercise of this Warrant have been at or prior to the date hereof, duly
authorized by all necessary corporate action on the part of the Company. No
person has any right of first refusal or any preemptive rights in connection
with the issuance and sale of the Shares. The shares of Common Stock will be
duly and validly issued, fully paid and non-assessable, with no personal
liability attaching ownership thereof, will be free and clear of all liens,
charges, restrictions, claims and encumbrances imposed by or through the
Company and will be free of restrictions on transfer other than restrictions on
transfer under this Warrant Agreement, the Registration Rights Agreement and
under applicable state and federal securities laws. (e) Since September 30, 2003, the Company has filed all reports,
schedules, forms, statements and other documents required to be filed by it
with the Securities and Exchange Commission (SEC) pursuant to the reporting
requirements of the Securities Exchange Act of 1934, as amended (the 1934
Act) (all of the foregoing filed prior to the date hereof and all exhibits
included therein and financial statements and schedules thereto and documents
incorporated by reference therein being hereinafter referred to as the SEC
Documents). As of their respective dates, the SEC Documents complied in all
material respects with the requirements of the 1934 Act and the rules and
regulations of the SEC promulgated thereunder applicable to the SEC Documents,
and none of the SEC Documents, at the time they were filed with the SEC,
contained any untrue statement of a material fact or omitted to state a
material fact required to be stated therein or necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading. All material agreements to which the Company is a party or to
which the property or assets of the Company are subject have been filed as
exhibits to the SEC Documents as required. As of their respective dates, the
financial statements of the Company included in the SEC Documents complied as
to form in all material respects with applicable accounting requirements and
the published rules and regulations of the SEC with respect thereto. Such
financial statements have been prepared in accordance with accounting
principles generally accepted in the United States of America, consistently
applied during the periods involved (except (i) as may be otherwise indicated
in such financial statements or the notes thereto, or (ii) in the case of
unaudited interim statements, to the extent they may exclude footnotes or may
be condensed or summary statements) and fairly present in all material respects
the consolidated financial position of the Company and its subsidiaries as of
the dates thereof and the results of their operations and cash flows for the
periods then ended (subject, in the case of unaudited statements, to normal
year-end immaterial audit adjustments). (f) So long as the Company beneficially owns the Common Shares that may be
issued upon the exercise of this Warrant, the Company shall timely file all
reports required to be filed with the SEC pursuant to Section 13 and 15(d) of
the 1934 Act and shall not terminate its status as an issuer required to file
reports under the 1934 Act where the rules and regulations thereunder would
permit such termination. The Company will take all reasonable action under its
control to maintain the continued listing and quotation and trading of the
Common Stock on the OTC Bulletin Board and will comply with the Companys
reporting, filing and other obligations under the by-laws or rules of the
National Association of Securities Dealers, Inc. applicable to it at least so
long as the Company beneficially owns the Common Shares that may be issued upon
the exercise of this Warrant. In the event the Company applies for listing on
any national securities exchange or on the Nasdaq Stock Market, the Company
will include the shares of Common Stock underlying this Warrant in any such
application. (g) The Company shall reserve, free from preemptive rights, out of its
authorized but unissued shares, sufficient shares to provide for the exercise
of this Warrant from time to time; provided that nothing contained herein shall
be construed to preclude the Company from satisfying its obligations in respect
of the issuance of shares by delivery of repurchased shares of Common Stock
which are held in the treasury of the Company. 5

addressed to the address specified on the cover page hereof, and if to the
Holder, it will be addressed to the registered Holder at its, his or his
address as it appears on the books of the Company. 12. Remedies. The Company stipulates that the remedies at law of the Holder in the event
of a default or threatened default by the Company in the performance of or
compliance with any of the terms of this Warrant are not and will not be
adequate, and that such terms may be specifically enforced by a decree for the
specific performance of any agreement contained herein or by an injunction
