FOR VALUE RECEIVED, Digicorp, a corporation organized under the laws of Delaware
with an address at 4143 Glencoe Avenue, Marina Del Rey, CA 90292 (Fax No.: (310)
651-9629) (the "Maker"), hereby promises to pay to Jay Rifkin with an address at
1723 Cloverfield Blvd., Santa Monica, CA 90404, or assigns (the "Holder"), the
principal sum of Seventy Five Thousand Dollars ($75,000) in lawful money of the
United States, plus interest thereon at the rate set forth below, ON DEMAND.

1. Payments.

      Maker promises to pay interest on the principal amount of this Note
outstanding at a rate equal to the "prime rate" published in The Wall Street
Journal from time to time to the date of payment in full. Maker hereby agrees to
repay the principal amount of this Note, and the interest which shall accrue on
this Note, upon written demand therefor by the Holder. When any date on which
principal and interest are due and payable falls on a Saturday, Sunday or legal
holiday, then such payment shall be due and payable on the first business day
immediately following.

      Prepayment of all or any part of the principal due and owing on this Note
may be made on any date without any additional premium or penalty. All payments
made on this Note shall be applied first to amounts other than principal and
interest which may then be due hereunder, then to interest accrued to the date
of the payment and then to the outstanding principal amount of this Note.

      In the event any payment due hereunder is not made within five (5) days
after the due date, interest shall accrue on such unpaid amount at the rate of
fifteen percent (15%) per annum from the due date.

2. Waivers.

      No delay or failure on the part of the Holder in exercising any right,
privilege or option hereunder shall operate as a waiver thereof or of any event
of default, nor shall any single or partial exercise of any such right,
privilege or option preclude any further exercise thereof, or the exercise of
any other right, privilege or option.

      Makers waive demand, presentment for payment, notice of dishonor, protest
and notice of protest and any notice or demands of any kind are hereby expressly
waived.

of the United States District Courts in the State of California for the purpose
of any suit, action or other proceeding arising out of or based upon this Note,

described or (ii) in any other manner provided by or pursuant to the laws of
such other jurisdiction; provided, however, that Holder may at its option bring
suit, or institute other judicial proceedings, against Makers or any of their
assets in any state or Federal court of the United States or of any country or

already relied on the waiver in entering into this Note and that Holder will
continue to rely on the waiver in related future dealings. This waiver shall
apply to any subsequent amendments, renewals, supplements or modifications to
this Note.
