  Reference is made to (i) that certain Securities Purchase Agreement, dated as
of July 8, 2004 (as amended, modified or supplemented from time to time, the
"Purchase Agreement"), by and between RPM Technologies, Inc., a Delaware
corporation (the "Company"), and Laurus Master Fund, Ltd. (the "Purchaser") and
(ii) that certain Restricted Account Agreement, dated as of July 8, 2004 (as
amended, modified or supplemented from time to time, the "Restricted Account
Agreement"), by and among the Company, Laurus and North Fork Bank (the "Bank").
Capitalized terms used but not defined herein shall have the meanings ascribed
them in the Purchase Agreement or the Restricted Account Agreement, as
applicable.  Pursuant to Section 3.2 of the Purchase Agreement, the Company is
required to place $2,200,000 in the Restricted Account, and, subject to the
provisions of this letter, the Purchase Agreement, the Restricted Account
Agreement and any Related Agreement, except as otherwise contemplated below,
maintain such amount in the Restricted Account for as long as the Purchaser
shall have any obligations outstanding under the Note and to assign the
Restricted Account for the benefit of the Purchaser as security for the
performance of the Company's obligations to the Purchaser.

  The Purchaser and the Company desire to clarify certain aspects regarding the
use of funds contained in the Restricted Account. For good consideration, the
receipt and sufficiency of which is here acknowledged, the Company and the
Purchaser agree that, so long as no Event of Default has occurred and is
continuing, (w) following either (I) the provision by the Company to the
Purchaser of evidence that the Company and its Subsidiaries have obtained
general liability insurance with a coverage limit of no less than $1,200,000 or
(II) the Purchaser has determined (in its sole discretion) that the general
liability insurance referred to in the immediately preceding clause (I) is not
customary with respect to the Company's and its Subsidiaries' business
operations, the Purchaser shall direct the Bank, pursuant to a Release Notice
(as defined in the Restricted Account Agreement), to wire an amount of funds
equal to $100,000 to such bank account as the Company may direct the Purchaser
in writing, (x) following the execution of a Lease by the Company, the Purchaser
shall direct the Bank, pursuant to a Release Notice, to wire an amount of funds
equal to $100,000 to such bank account as the Company may direct the Purchaser
in writing, (y) following the filing of the initial Registration Statement
referred to in the Registration Rights Agreement, the Purchaser shall direct the
Bank, pursuant to a Release Notice, to wire an amount of funds equal to $100,000
to such bank account as the Company may direct the Purchaser in writing, and (z)
with respect to up to $1,000,000 of the proceeds contained in the Restricted
Account, following the provision by the Company to the Purchaser in writing of
evidence that the Company has entered into an agreement or agreements to
consummate one or more Equipment Purchases, the Purchaser shall direct the Bank,
pursuant to a Release Notice, to wire an amount of funds equal to the
corresponding dollar amount necessary to be paid to the seller of the equipment
related to such Equipment Purchase (a "Seller") at such time, which wire shall
be made directly to such Seller's bank account; provided that (i) with respect
to any release referred to in this clause (z) (other than with respect to
deposits required to be paid by the Company to a Seller), the Purchaser shall
not be required to direct any such release unless and until (A) the Company (I)
has obtained customary insurance  insuring the Company against any loss related
to the equipment acquired in connection with each such Equipment Purchase and
(II) is otherwise in compliance with Section 6.8 of the Purchase Agreement  and
(B) the Company has entered into the Lease and (ii) notwithstanding anything to
the contrary contained above, in no event shall the aggregate amount that the
Purchaser is required to release from the Restricted Account pursuant to the
preceding clauses (w) through (z), inclusive, exceed $1,300,000.  Furthermore,
in addition to the foregoing, for good consideration, the receipt and
sufficiency of which is here acknowledged, the Company and the Purchaser agree
that when (and not until) the Amortizing Principal Amount (as defined in the
Note) at such time has been reduced (through conversions or otherwise) to $0,
promptly following any conversion of a Monthly Principal Amount (as defined in
the Note) or such other portion of the aggregate Principal Amount into Common
Stock of the Company (such event, a "Conversion"), the Purchaser shall direct
the Bank, pursuant to a Release Notice (as defined in the Restricted Account
Agreement), to wire an amount of funds equal to the corresponding dollar amount
by which the aggregate Principal Amount of the Note has been reduced pursuant to
such a Conversion from the Restricted Account to such bank account as the
Company may direct the Purchaser in writing.

signed by the Company and the Purchaser.  This letter may be executed in any
number of counterparts, each of which shall be an original and all of which,
when taken together, shall constitute one agreement.  Delivery of an executed
