December 17, 2001

Mr. Frederick A. Ball
[Address intentionally omitted.]

Dear Fred,

         In connection with the Employment Agreement dated September 16, 1999,
between you and Borland Software Corporation ("Borland"), as amended on May 30,
2000 (collectively, the "Employment Agreement") and in connection with the
Change in Control Agreement effective May 31, 2000 between you and Borland (the
"Change in Control Agreement"), subject to the approval of the Borland Board of
Directors, the Employment Agreement and the Change in Control Agreement are
hereby amended as set forth herein.

         All references in the Employment Agreement and the Change in Control
Agreement to "INPRISE Corporation" shall be amended to read "Borland Software
Corporation" and all references to "INPRISE" and the "Company" shall be amended
to read "Borland". A section shall be added to the Employment Agreement reading
as follows:1

         "Additional Payment:
         -------------------

                 (a) In the event that any payment or benefit received or to be
received by you pursuant to this Agreement or any other Borland plan, agreement
or arrangement (collectively, the "Payments") would be subject to the excise tax
imposed by Section 4999 of the Internal Revenue Code of 1986, as amended (the
"Code"), or any similar or successor provision (the "Excise Tax"), Borland shall
pay to you within ninety (90) days of the date you become subject to the Excise
Tax, an additional amount (the "Gross-Up Payment") such that the net amount
retained by you, after deduction of (1) any Excise Tax on the Payments and (2)
any federal, state and local income or employment tax and Excise Tax upon the
payment provided for by this paragraph, shall be equal to the Payments.

                 (b) For purposes of determining whether any of the Payments
will be subject to the Excise Tax and the amount of such Excise Tax:

                           (1) Any other payments or benefits received or to be
                  received by you in connection with transactions contemplated
                  by a "change in control" or your termination of employment
                  (whether pursuant to the terms of this Agreement or any other
                  plan, arrangement or agreement with Borland), shall be treated
                  as "parachute payments" within the meaning of Section 280G of
                  the Code or any similar or successor provision, and all
                  "excess parachute payments" within the meaning of Section 280G
                  or any similar or successor provision shall be treated as
                  subject to the Excise Tax, unless in the opinion of Borland's
                  independent auditors such other payments or benefits (in whole
                  or in part) represent reasonable compensation for services
                  actually rendered within the meaning of Section 280G (or any
                  similar or successor provision of the Code) in excess of the
                  base amount within the meaning of Section 280G (or any similar
                  or successor provision of the Code), or are otherwise not
                  subject to the Excise Tax.

                           (2) The amount of the Payments which shall be treated
                  as subject to the Excise Tax shall be equal to the lesser of
                  (i) the total amount of the Payments or (ii) the amount of the
                  excess parachute payments within the meaning of Section 280G
                  after applying paragraph (b)(1) above.

The value of any non-cash benefits or any deferred payment or benefit shall be
determined by Borland's independent auditors in accordance with the principles
of Section 280G of the Code.

                 (c) For purposes of determining the amount of the Gross-Up
Payment, you shall be deemed to pay federal income taxes at the highest marginal
rate of federal income

----------------------
1 Capitalized terms used but not defined herein shall have the meanings ascribed
thereto in the Employment Agreement.

<PAGE>

taxation in the calendar year in which the Gross-Up Payment is to be made and
state and local income taxes at the highest marginal rate of taxation in the
state and locality of your residence on the date the Gross-Up Payment is to be
made, net of the maximum reduction in federal income taxes which could be
obtained from deduction of such state and local taxes.

                 (d) In the event that the Excise Tax is determined to be less
than the amount taken into account hereunder, you shall repay to Borland, at the
time that the amount of such reduction in Excise Tax is finally determined, the
portion of the Gross-Up Payment attributable to such reduction (plus the portion
of the Gross-Up Payment attributable to the Excise Tax and federal, state and
local income and employment taxes imposed on the Gross-Up Payment being repaid
by you if such repayment results in a reduction in Excise Tax and/or a federal,
state or local income or employment tax deduction) plus interest on the amount
of such repayment at the rate provided in Section 1274(b)(2)(B) of the Code.

                 (e) In the event that the Excise Tax is determined to exceed
the amount taken into account hereunder (including by reason of any payment the
existence or amount of which cannot be determined at the time of the Gross-Up
Payment), Borland shall make an additional gross-up payment in respect of such
excess (plus any interest payable with respect to such excess) at the time that
the amount of such excess is finally determined."

         In addition, Section 5 of the Change in Control Agreement shall be
deleted in its entirety and you shall be entitled to a gross up payment with
respect to payments made pursuant to the Change in Control Agreement in the same
manner as provided in the Employment Agreement.

         Other than as expressly modified above, all of the other terms and
conditions of the Employment Agreement and the Change in Control Agreement shall
remain in full force and effect without modification.

                                  Sincerely,

                                  BORLAND SOFTWARE CORPORATION
