    The undersigned, General Automation, Inc., a Delaware corporation, for value

    The following is a statement of the rights of the Holder of this Note and
the conditions to which this Note is subject:

1.         Interest. The unpaid principal balance of this Note outstanding from

2.         Payments. Subject to Section 3 below, the entire principal amount of
this Note, together with all accrued interest thereon, shall be due and payable
on the earliest to occur of the date which is one hundred twenty (120) days
following the date of this Note (the "Maturity Date"); or the third business day
following the closing of a loan to the undersigned pursuant to that certain Loan
Agreement (the "Loan Agreement") of even date herewith between the undersigned
and Pacific Mezzanine Fund LLP ("PMF"), which loan yields gross proceeds to the
undersigned of not less than One Million Fifty Thousand Dollars ($1,050,000),
excluding the initial $3,150,000 loaned by PMF to the Company pursuant to the
Loan Agreement; or the third business day following the closing of any other

3.         Satisfaction of Obligations by Undersigned. Notwithstanding Section 2
above, in the event that a Qualifying Financing has not been consummated on or
before the Maturity Date, the undersigned may, in its sole discretion, by
written notice given by the undersigned to the Holder, elect to satisfy the
undersigned's entire obligation under this Note by executing and delivering to
the Holder a Secured Convertible Promissory Note with an original principal
amount equal to the sum of the then outstanding principal balance of this Note
and all accrued but unpaid interest then owed on this Note, upon and subject to

4.         Prepayment. The undersigned may at any time prepay this Note in whole
or in part. All payments made on this Note shall be applied first to accrued
interest, and the balance of such payment, if any, shall be applied to
principal, and interest shall thereupon cease upon the principal so credited.

5.         Headings. The headings of this Note have been inserted as a matter of
convenience and shall not affect the construction hereof.

6.         Applicable Law. This Note shall be governed by and construed in

pertaining to enforcement of the terms of this Note or to the declaration of
rights hereunder (collectively, an "Action"), the losing party shall pay to the
prevailing party a reasonable sum for attorneys' fees and costs (at the
prevailing party's attorneys' then-prevailing rates) incurred in bringing and
prosecuting such Action and/or enforcing any judgment, order, ruling, or award
(collectively, a "Decision") granted therein, all of which shall be deemed to
have accrued on the commencement of such Action and shall be paid whether or not
such Action is prosecuted to a Decision. Any Decision entered in such Action
shall contain a specific provision providing for the recovery of attorneys' fees
and costs incurred in enforcing such Decision. The court or arbitrator may fix
