                       MODIFICATION OF BUSINESS ASSET SALE,
                     LICENSE AGREEMENT & ASSIGNMENT OF RIGHTS

This Agreement supersedes the Business Asset Sale, License Agreement &
Assignment of Rights that was originally executed on July 1, 2003.
Effective September 15, 2003, the parties agree by and between:

       Sonic Jet Performance, Inc., a Colorado company ("Seller")

                                - and -

       Rockwell Power Systems, Inc., a Delaware company ("Buyer").

                                  WITNESSETH

     Whereas, Seller owns and operates several business units,
including a Fire & Rescue Boat Division doing business under the name
of "Sonic Jet Performance;" and

     Whereas, Buyer desires to affiliate with Seller by acquiring
certain assets of such Division in exchange for a portion of its
capital stock; and

     Whereas, Seller is willing to transfer such assets to Buyer
subject to the terms and conditions hereof, and in connection
therewith is willing to license the use of the "Sonic Jet Performance"
name to Buyer and to assign to Buyer certain contractual rights
relating to the manufacture of the Fire & Rescue boats; and

     Whereas, Buyer is willing to license such name and accept such
assignment subject to the terms and conditions hereof;

     Now, therefore, in consideration of foregoing preamble and the mutual
agreements contained herein, the Parties agree as follows:

Sale of Business Division Assets

For and in consideration of the purchase price and other obligations
set forth herein, the Seller hereby sells to Buyer and Buyer hereby
buys from Seller all Seller's right, title and legal interest in and
to the tangible and intangible assets of its Fire & Rescue Boat
Division which are set forth on the "Bill of Sale" attached hereto as
Exhibit A (the "Assets").  The parties acknowledge and agree that such
sale and transfer is expressly limited to the items set forth in
Exhibit A and shall not be construed so as to transfer any legal
interest whatsoever to Buyer in any of Seller's other assets or
business operations.

In addition, for consideration for payment equal to the book value of
the assets, the Seller agrees to transfer any and all remaining assets
associated with the recreational boat business on or before March 1, 2004.

In connection with such sale of Assets, Seller hereby consents to the
transfer of employment to Buyer of the Fire & Rescue Division
employees listed on the "Employee Transfer Consent" attached hereto as
Exhibit B.

Grant of License

As additional consideration for payment of the purchase price and the
other obligations set forth herein, the Seller hereby grants to the
Buyer for a period of 20 years an irrevocable, transferable but non-
exclusive right (the "License") to use the name "Sonic Jet
Performance" as a trade name in connection with the operation of the
Fire & Rescue Boat Division business (the "SJP Name").  There shall be
no other use of the SJP Name.  In connection with the License, the
Buyer may market and sell Fire & Rescue boats anywhere in the world
using the SJP Name and the goodwill associated therewith, provided
however that all marketing and sales activities in the Middle East
(including Egypt, Lebanon, Turkey, Syria, Jordan, Iraq, Iran, Saudi
Arabia, Bahrain, Oman, Qatar, the UAE and Yemen) shall be conducted
through the Mohammed Al Rashid Establishment in Jeddah, Saudi Arabia.

Assignment of Contract Rights

In connection with the sale of Assets and in furtherance thereof,
Seller hereby assigns to Buyer the Seller's contractual right to use
the Fire & Rescue Jet Design as provided for under that certain "2001
License Agreement" made by and between Seller and Mardikian Marine
Design et al and dated December 27, 2001.  Buyer acknowledges receiving
a copy of such Agreement, and confirms its understanding that the
assignment of rights hereunder relates only to the Fire & Rescue boat
Design and not to any other Design covered by such agreement.
Furthermore Buyer hereby covenants and warrants that it will comply
with the Seller's obligations set forth in such agreement, including
the requirement to pay royalties on the sale of Fire & Rescue boats.
