         FOR VALUE RECEIVED, HEURISTIC PHYSICS LABORATORIES, INC., a California

resident ("Lender"), or order, the principal sum of One Million Five Hundred
Thousand Dollars and No Cents ($1,500,000.00), on ____________, 200_, [TWELVE
MONTHS FROM THE DATE OF ISSUANCE OF THIS NOTE] (the "Due Date") and to pay

prepayment on the amount prepaid.

         Borrower waives diligence, presentment, protest and notice of protest,
dishonor and nonpayment of this Note, and expressly agrees that this Note, or
any payment under it, may be extended and any security may be accepted, released
or substituted by the holder from time to time without in any way affecting the

principal or interest (including any interest which, but for the provisions of
the Bankruptcy Code, would have accrued on such amounts) when due and payable or
when declared due and payable; or (2) Borrower's material failure to comply with
any of the material provisions, conditions, covenants, or agreements in, or the

Event of Default shall occur under clause (2) unless Lender shall have given

the default within said 10-day period, Lender may proceed with its rights and
remedies under this Note.

collection or enforcement of this Note including, but not limited to, reasonable
attorneys' fees, incurred by the holder.

         This Note shall be governed by and construed in accordance with the
laws, without regards to the laws as to choice or conflict of laws, of the State
of California.

         EXECUTED at San Jose, California.
