one million dollars ($1,000,000). The Additional Stock shall be valued at the

Stock (the "Additional Escrow Agreement") is executed by and among the parties.
For the purpose of this paragraph, a Fair Market Valuation for the Additional
Stock on any given day shall be equal to the closing price reported for the
Stock on the National Association of Securities Dealers Automated Quotation
System (NASDAQ) two business days prior to the date of the Escrow Agreement.

         The Original Stock and the Additional Stock (collectively, the "Stock")
shall be placed in a segregated account to be held by an escrow agent for the
purpose of securing payment of the Loan. Following the execution and delivery of
this Agreement, the parties shall enter into the Additional Escrow Agreement

Additional Escrow Agreement is attached hereto as Exhibit A. Simultaneously with
the execution and delivery of the Additional Escrow Agreement, the Borrower
shall deliver the Additional Stock to the Escrow Agent.

fails to satisfy his obligations hereunder in accordance with the payment terms
of Section 2.2 and fails to make interest and principal payments required
hereunder by September 30, 2001,

1999, Lender shall, in addition to all other legal and equitable remedies, have
recourse to the Stock but only in amounts equal to the principal and interest
amounts remaining due and unpaid. Within thirty days following the last day of
the Term, Lender shall provide Borrower and Escrow Agent with notice ("Notice to
Recover") of its intention to recover amounts due and outstanding out of the
escrowed Stock. If Borrower fails to satisfy his obligations under Section 2.2
within 15 days of his receipt of Notice to Recover, the Escrow Agent shall
release and provide to Lender escrowed Stock equal to the amount due and
outstanding from Borrower to Lender. The value of the Stock at the time that
Lender shall be entitled to recourse thereto (i.e., in the event borrower fails
to satisfy his obligations hereunder) shall be determined by a Fair Market
Valuation. For the purpose of this paragraph, a Fair Market Valuation on any
given day shall be equal to the closing price reported for the Stock on the
National Association of Securities Dealers Automated Quotation System (NASDAQ)
for the 30 business days prior to the date of this Agreement.

         SECTION 2.7. RELEASE OF ESCROW SECURITIES TO BORROWER. Upon the earlier
of (1) notice jointly provided to the Escrow Agent that the interest and
principal amounts due hereunder have been paid; or (2) September 30, 2002, all
Stock remaining in escrow shall be released and returned to Borrower.

         SECTION 2.8. FURTHER SECURITY. Borrower and Lender agree that this Loan
shall be secured by, and Lender shall have legal recourse to, all of Borrower's
personal estate, including, but not limited to, all now-owed and hereafter
acquired real or personal property, deposit accounts, money, insurance proceeds,
securities and rights to payment of every kind and description, and all of
Borrower's contract rights, and all of Borrower's rights, remedies, interest,
security and liens, in any real or personal property. Lender's right of recourse
to the security described herein shall be secondary to any pre-existing security
interests in such property held by any other Persons.
