      FOR VALUE RECEIVED, Warp Technology Holdings, Inc. (the "Company") hereby
promises to pay to the order of ________________________ or its successors,
assigns and legal representatives (the "Holder"), at

with interest thereon at a rate of 10.0% per annum (subject to adjustment as set
forth in Section 2(b) below).

      1. Company Notes. This Note (the "Note") is one of a series of Notes (the
"Company Notes") of like tenor in an aggregate principal amount of up to
$6,500,000 (Six Million Five Hundred Thousand Dollars) issued by the Company
pursuant to the terms of the Note and Warrant Purchase Agreement, dated of even
date herewith (the "Purchase Agreement"), among the Company and the investors
party thereto. Capitalized terms used herein shall have the respective meanings
ascribed thereto in the Purchase Agreement unless otherwise defined herein.

      2. Maturity Date.

            (a) Subject to the provisions of subsection (b) and Section 6 below,
the aggregate principal amount of this Note and accrued interest thereon shall
be due and payable on [ ], 2005 (the "Maturity Date").

            (b) In the event that the Company has not refinanced the Company
Notes by the Maturity Date, the Maturity Date may be extended for up to 30 days
(the "Extension Period") upon written notice (an "Extension Notice") by the

                  (i) the interest rate under this Note shall be increased to
15.0% per annum during the term of the Extension Period; and

                  (ii) simultaneously with the delivery of the Extension Notice,
the Company shall deliver to the Holder a duly executed Additional Warrant to
purchase such number of Warrant Shares as is set forth in the Purchase
Agreement.

      3. Calculation and Payment of Interest. Interest hereunder shall be

Interest shall be calculated on a simple interest basis and shall accrue daily
and be payable quarterly, in arrears.

      4. Prepayment. Any prepayments hereunder shall be applied first, to the
payment of any expenses then owed to the Holder, second, to accrued interest on
this Note and third, to the payment of the principal amount outstanding under
this Note. The Company shall not have the right to set off or otherwise deduct
from amounts payable by it hereunder any amounts whether liquidated or
unliquidated, which the Holder or any of its Affiliates may owe to the Company,
which right is hereby expressly waived to the maximum extent permitted by
applicable law. The Company shall have no right to make any prepayment of all,
or any portion of this Note unless the Company makes a simultaneous prepayment
of the other Notes under the Purchase Agreement pari pasu.

      5. Covenants. The Company agrees that, so long as any amount payable under
this Note remains unpaid, it will not, and will cause its Subsidiaries not to,

services, except trade payables arising in the ordinary course of business
consistent with past practices, (v) as lessee under capitalized leases, (vi)
secured by a Lien (as defined below) on any asset of the Company or a

borrowed money existing on the date of this Note or other obligations or other
liabilities incurred in connection with Liens permitted to be incurred under
Section 5(b)(vi) or 5(b)(vii) hereof;

ordinary course of business;

                  (v) zoning restrictions, easements, licenses, covenants,

a whole or impair the use of such property in the operation of the Company's or
its Subsidiaries' businesses; and

                  (vi) other Liens incidental to the conduct of the business of
the Company or a Subsidiary or the ownership of its or their respective property
and assets which were not incurred in connection with the borrowing of money,

(which acceleration is not rescinded, annulled or otherwise cured within ten
(10) days of receipt by the Company or such Subsidiary of notice of such
acceleration);

            (h) Any material covenant, agreement or obligation of the Company in
any Transaction Document shall cease to be enforceable, or shall be determined
to be unenforceable in any material respect; or any of the security interests
granted pursuant to the Security Agreement shall be determined to be void,
voidable, invalid or unperfected, are subordinated or are ineffective to provide
the Holder with a perfected, first priority security interest in the collateral
covered by the Security Agreement, subject to the terms and conditions of the
Transaction Documents;

            (i) The Company shall sell, transfer, lease or otherwise dispose of

the foregoing;

            (j) One or more judgments in an aggregate amount in excess of Fifty

            (k) The Company shall have applied for or consented to the

                                      -4-
<PAGE>

become due by means of available assets, or has made a general assignment for
the benefit of creditors; or the Company files a voluntary petition in
bankruptcy, or a petition or an answer seeking reorganization or an arrangement
with creditors or seeking to take advantage of any insolvency law, or an answer
admitting the material allegations of a petition in any bankruptcy,
reorganization or insolvency proceeding or has taken action for the purpose of
effecting any of the foregoing; or if, within sixty (60) days after the
commencement of any proceeding against the Company seeking any reorganization,
rehabilitation, arrangement, composition, readjustment, liquidation, dissolution
or similar relief under the Federal bankruptcy code or similar order under
future similar legislation, the appointment of any trustee, receiver, custodian,
liquidator, or other court-appointed fiduciary of the Company or of all or any
substantial part of its properties, such order or appointment shall not have

            Upon the occurrence of any Event of Default, the Holder may, at its
option, declare all amounts due hereunder to be due and payable immediately and,
upon any such declaration, the same shall become and be immediately due and
payable. If an Insolvency Event occurs with respect to the Company or any
Subsidiary, then all amounts due hereunder shall become immediately due and
payable without any declaration or other act on the part of the Holder. Upon the
occurrence of any Event of Default, the Holder may, in addition to declaring all
amounts due hereunder to be immediately due and payable, pursue any available
remedy, whether at law or in equity, including, without limitation, exercising
its rights under the Security Agreement. If an Event of Default occurs, the
Company shall pay to the Holder the reasonable attorneys' fees and disbursements
and all other reasonable out-of-pocket costs incurred by the Holder in order to
collect amounts due and owing under this Note or otherwise to enforce the
Holder's rights and remedies hereunder and under the Security Agreement.

presentment for payment, protest, demand, notice of protest, notice of
non-payment and diligence with respect to this Note, and waives and renounces
all rights to the benefit of any statute of limitations or any moratorium,
appraisement, exemption or homestead now provided or that hereafter may be
provided by any federal or applicable state statute, including but not limited
to exemptions provided by or allowed under the Federal Bankruptcy Code, both as
to itself and as to all of its property, whether real or personal, against the
enforcement and collection of the obligations evidenced by this Note and any and
all extensions, renewals and modifications hereof.

                                      -5-
<PAGE>

      No failure on the part of the Holder hereof to exercise any right or
remedy hereunder with respect to the Company, whether before or after the
happening of an Event of Default, shall constitute a waiver of any future Event
of Default or of any other Event of Default. No failure to accelerate the debt
of the Company evidenced hereby by reason of an Event of Default or indulgence
granted from time to time shall be construed to be a waiver of the right to
insist upon prompt payment thereafter; or shall be deemed to be a novation of
this Note or a reinstatement of such debt evidenced hereby or a waiver of such
right of acceleration or any other right, or be construed so as to preclude the
exercise of any right the Holder may have, whether by the laws of the state
governing this Note, by agreement or otherwise; and the Company hereby expressly
waives the benefit of any statute or rule of law or equity that would produce a
result contrary to or in conflict with the foregoing.

      9. Amendment; Waiver. Any term of this Note may be amended or waived upon
the written consent of the Company and the holders of Company Notes representing
at least 50% of the principal amount of Company Notes then outstanding (the
"Majority Holders"); provided, that (x) any such amendment or waiver must apply
to all outstanding Company Notes; and (y) without the consent of the Holder
hereof, no amendment or waiver shall (i) subject to Section 2(b) hereof, change
the Maturity Date of this Note, (ii) reduce the principal amount of this Note or
the interest rate due hereon, or (iii) change the place of payment of this Note.
No such waiver or consent on any one instance shall be construed to be a
continuing waiver or a waiver in any other instance unless it expressly so
provides.

      10. Transfers. The Holder shall have the right to transfer this Note or
any interest herein in any transaction meeting the requirements of applicable
securities laws.

      11. Intercreditor Agreement. This note is subject to the terms and
conditions of the Intercreditor Agreement and Collateral Agency Agreement.

      12. Governing Law; Consent to Jurisdiction. This Note shall be binding
upon the Company and its successors, assigns and legal representatives. The
validity, construction and interpretation of this Note will be governed, and
construed in accordance with, the laws of the State of New York. EACH OF THE
COMPANY AND, BY ITS ACCEPTANCE HEREOF, THE HOLDER HEREBY WAIVES ANY RIGHT TO
REQUEST A TRIAL BY JURY IN ANY LITIGATION WITH RESPECT TO THIS NOTE AND
REPRESENTS THAT COUNSEL HAS BEEN CONSULTED SPECIFICALLY AS TO THIS WAIVER.

      Each of the Company and, by its acceptance of this Note, the Holder
irrevocably submits to the exclusive jurisdiction of the courts of the State of
New York located in New York County and the United States District Court for the
Southern District of New York for the purpose of any suit, action, proceeding or
judgment relating to or arising out of this Note and the transactions
contemplated hereby. Service of process in connection with any such suit, action
or proceeding may be served on the Company and the Holder

                                      -6-
<PAGE>

anywhere in the world by the same methods as are specified for the giving of
notices under the Purchase Agreement. Each of the Company and, by its acceptance
of this Note, the Holder irrevocably consents to the jurisdiction of any such
court in any such suit, action or proceeding and to the laying of venue in such
court. Each of the Company and, by its acceptance of this Note, the Holder
irrevocably waives any objection to the laying of venue of any such suit, action
or proceeding brought in such courts and irrevocably waives any claim that any
such suit, action or proceeding brought in any such court has been brought in an
inconvenient forum.
