         1. Time and Place of Payment. The unpaid and unforgiven Principal
Amount, together with all accrued, unpaid and unforgiven interest, shall be due
and payable on May 18, 2005, subject to required pre-payment, in whole or in
part, to the extent hereinafter provided. All payments due hereunder shall be
made at the offices of Inprise Corporation, 100 Enterprise Way, Scotts Valley,

writing and shall be made in immediately available funds. Borrower agrees and
acknowledges that upon Note Holder's request it shall provide Note Holder with
any reasonable documentation or authorization required to permit Note Holder to

payments due and payable hereunder.

         2. Use of Proceeds. Borrower agrees that the Principal Amount may only
be used for the purchase of the residence located at [Address Intentionally

         4. Forgiveness of Indebtedness. Notwithstanding any of the foregoing
provisions of this Note, Inprise shall forgive $200,000 of the Principal Amount
and accrued interest, then due and owing on May 18, 2001; an additional $200,000
of the Principal Amount and interest, then due and owing on May 18, 2002; an
additional $200,000 of the Principal Amount and interest, then due and owing on
May 18, 2003; an additional $200,000 of the Principal Amount and interest, then
due and owing on May 18, 2004; and the remainder of the Principal Amount and
interest then due and owing on May 18, 2005, if on such date all the following
conditions are met:

                  (i) Borrower has, at all times since the date of this Note
         remained in the full-time employ of Inprise; and

                  (ii) this Note has not been either (A) declared by Inprise to
         be immediately due and payable pursuant to its option to accelerate or
         (B) accelerated automatically by its terms.

         5. Interest Rate. The unpaid and unforgiven Principal Amount from time
to time shall bear interest at the rate of seven percent (7%) per annum (the
"Interest Rate"), and shall be computed on the basis of a 365 day year. Interest
shall accrue beginning on the date that the Principal Amount is disbursed to
Borrower and continuing until the full Principal Amount has been paid in full.
Any interest hereunder not paid when due shall be added to the Principal Amount
and bear interest thereon at the Interest Rate provided herein.

         6. Acceleration. It is hereby expressly agreed that the entire
outstanding Principal Amount and accrued but unpaid interest owing under this
Note shall become due and payable, at the option of the Note Holder, (i) upon
the happening of any default in the performance of Borrower's obligation under
the Deed of Trust, this Note, the First Deed of Trust (as defined in the Deed of
Trust) or any note secured thereby, or other Loan Documents to which Borrower is
a party, or upon the happening of an event by which, under the terms of the Deed
of Trust, Note, First Deed of Trust or any note secured thereby, said principal
sum may or shall become due and payable; (ii) upon the termination of Employee's
employment with Inprise for any reason; (iii) upon the death of Employee; or
(iv) if Borrower breaches any of the representations made thereby which are
contained in this Note.

                  When Borrower is in default as described above, and the Note
Holder does not elect to accelerate the entire Principal Amount and accrued
interest thereon due and owing, the Note Holder shall not be deemed to have
waived any rights hereunder.

         7. Payments and Withholding Taxes. To provide for the payment of
Federal, State and local income and employment taxes required to be withheld
from the Employee at the time any portion of the Principal Amount and interest
may be forgiven ("Withholding Taxes"), the Employee agrees that after any such
forgiveness to pay to Inprise (and Employee authorizes Inprise to deduct and
withhold from the compensation otherwise due to the Employee) on each payday a
proportionate part of the Withholding


                                       2
<PAGE>   3

Taxes due upon the forgiveness of any portion of the Principal Amount and
interest. Inprise shall notify the Employee of the estimated amount of the
Withholding Taxes and the amount of each payment to be deducted on each payday.
If, on the date any installment of Principal Amount and interest is to be
forgiven, the amount theretofore paid by (or deducted from) Employee to Inprise
is less than the amount of the Withholding Taxes due with respect to the amount
forgiven, Employee shall promptly pay any deficiency to Inprise, and if the
amount paid is in excess of the amount of the Withholding Taxes due, Inprise
shall promptly pay such excess to Employee. Employee agrees to be solely
responsible for the payment of all taxes imposed on Employee which may become
due as a consequence of the loan evidenced hereby or the terms of this Note and
agrees to indemnify and hold harmless Inprise with respect to any failure on the
part of Inprise to collect any Withholding Taxes. Inprise makes no
representation as to the occurrence or non-occurrence of any tax event with
respect to this Note and Employee represents that he is not relying on Inprise
in any manner whatsoever in respect thereto.

         8. Costs and Expenses. Borrower agrees to pay any and all costs of
collection and enforcement, in case payment under this Note is not made when
due, or in case it becomes necessary to protect the security for this Note,
whether or not suit is commenced for such purpose, or in regard to any defenses
to the Note or counterclaim brought in the action to enforce this Note,
including attorneys' fees, court costs, title insurance expenses, costs of
appeal, and other costs incurred by the Note Holder in such circumstances.

         9. Waiver. Note Holder may, without waiving or losing any of its rights
under this Note: (i) accept late payments, (ii) accept partial payments marked
"paid in full," and (iii) delay in enforcing any of its rights under this Note,
and Borrower hereby expressly waives the benefit of any statute or rule of law
or equity now in effect, or which may hereafter be in effect, which would
produce a result contrary to or in conflict with the foregoing. The Borrower
waives presentment for payment, demand, notice of nonpayment, notice of protest,
and protest of this Note, diligence in collection or bringing suit. The
liability of Borrower shall be absolute and unconditional without regard to the

Section 11 below, and shall not extend or otherwise postpone the due date of
this Note.

         11. Application of Payments. All payments received by Note Holder shall

of Trust which shall be executed by the Borrower on the date hereof. Borrower
irrevocably appoints Inprise as his lawful attorney and agent to execute
mortgages, financing statements or other necessary documents in any appropriate
public office for the purpose of perfecting Note Holder's security interest in
the Collateral. At any time and from time to time, Borrower will use his best
efforts to execute and deliver all further instruments and documents, and take

or to a third party and such assignment shall not affect the Principal Amount,

contained in this Note. Upon receipt of any notice of such assignment from
Inprise, or its assignee, Borrower agrees to make all payments due hereunder
directly to such assignee who will then be Note Holder. Without the prior
written consent of Inprise, Borrower may not assign, delegate or otherwise
transfer his obligations hereunder, and the Residence may not be sold or
transferred subject hereto, without the prior written consent of this Note
Holder. Subject to the preceding sentence, this Note shall be binding upon the

illegal, invalid or unenforceable under present or future laws effective during
the term hereof, such provision shall be fully severable and this Note shall be
construed and enforced as if such illegal, invalid or unenforceable provision
had never comprised a part hereof and the remaining provisions hereof shall
remain in full force and effect and shall not be affected by the illegal,
invalid or unenforceable provision by its severance herefrom.

         24. Due on Sale Provisions. Paragraph 17 of the Deed of Trust securing
this Note shall contain a due on sale provision which reads as follows:

         "If all or any part of the Property or any interest in it is sold or
         transferred (or if beneficial interest in Borrower is sold or
         transferred and Borrower is not a natural person) without Lender's
         prior written consent, Lender may, at its option, require immediate
         payment in full of all sums secured by this Security Instrument.
         However, this option shall not be exercised by Lender if exercise is
         prohibited by federal law as of the date of this Security Instrument.

         If Lender exercises this option, Lender shall give Borrower notice of
         acceleration. The notice shall provide a period of not less than 30
         days from the date the notice is delivered or mailed within which
         Borrower must pay all the sums secured by this Security Instrument. If

         Lender may invoke any remedies permitted by this Security Instrument
         without further notice or demand on Borrower."
