Purchaser, all on the terms and subject to the conditions set forth in the
Securities Purchase Agreement and the other Investment Documents.  Unless
otherwise indicated, capitalized terms used herein shall have the meanings
assigned to such terms in the Securities Purchase Agreement.

     B.  The Company has advised the Purchaser that it wishes to purchase from
SSE Manufacturing, Inc., a California corporation (the "Seller"), on the terms
                                                        ------

subject to the conditions set forth in this Consent and Amendment.
