                              INPRISE CORPORATION
                          CHANGE IN CONTROL AGREEMENT

     This Change in Control Agreement (the "Agreement") is effective as of May
31, 2000, by and between Frederick A. Ball (the "Employee") and Inprise
Corporation, a Delaware corporation (the "Company").

                                   RECITALS

     A.   The Employee presently serves as Senior Vice President and Chief
Financial Officer of the Company and performs significant strategic and
management responsibilities necessary to the continued conduct of the Company's
business and operations.

     B.   The Board of Directors of the Company (the "Board") has determined
that it is in the best interests of the Company and its stockholders to assure
that the Company will have the continued dedication and objectivity of the
Employee, notwithstanding the possibility or occurrence of a Change in Control
(as defined below) of the Company.

     C.   The Board believes that it is imperative to provide the Employee with
certain severance benefits upon the Employee's termination of employment
following a Change in Control that will provide the Employee with enhanced
financial security and provide sufficient incentive and encouragement to the
Employee to remain with the Company following a Change in Control.

     D.   Certain capitalized terms used in the Agreement are defined in Section
6 below.

                                   AGREEMENT

     The Employee and the Company agree as set forth below:

     1.   Terms of Employment.  The Company and the Employee agree that the
          -------------------
Employee's employment is "at will" and that their employment relationship may be
terminated by either party at any time, with or without cause. During his
employment with the Company, the Employee agrees to devote his full business
time, energy and skill to his duties with the Company. These duties shall
include, but not be limited to, any duties consistent with the Employee's
position that may be assigned to the Employee from time to time by the Company
or the Board.

     2.   Stock Option Vesting Upon Change in Control.  Upon the occurrence of a
          -------------------------------------------
Change in Control, with respect to any unvested options to purchase shares of
the stock of the Company held by the Employee, the Employee shall immediately
become vested in full and such options will be exercisable for a period of 24
months following the occurrence of a Change in Control.

                                       1

     3.   Severance Benefits Upon Termination following a Change in Control.
          ------------------------------------------------------------------
Subject to the limitations set forth in Sections 4 and 5 below, if the
Employee's employment with the Company terminates following a Change in Control
the Employee shall be entitled to receive, in addition to the compensation and
benefits earned by the Employee through the date of his termination, severance
benefits as follows:

          (a)  Involuntary Termination. If the Employee's employment with the
               -----------------------
Company is terminated as a result of Involuntary Termination, then the Employee
shall be entitled to receive the following severance benefits:

               (i)    The Employee shall be entitled to receive severance pay in
an amount equal to one hundred percent (100%) of his or her annual base salary
as in effect at the time of such termination. Any severance to which the
Employee is entitled pursuant to this section shall be paid in a lump sum, less
applicable withholding, within thirty (30) days following the Employee's
termination.

               (ii)   The Company shall, if permitted under the Company's
existing health insurance plans, continue the Employee's existing group health
insurance coverage. If not so permitted, the Company shall reimburse the
Employee for any COBRA premiums paid by the Employee for continued group health
insurance coverage. Such health insurance coverage or reimbursement of COBRA
premiums shall continue until the earlier of (1) twelve (12) months after the
date of the Employee's Involuntary Termination or (2) the date on which the
Employee commences New Employment.

          (b)  Voluntary Resignation; Termination For Cause.  If the Employee's
               --------------------------------------------
employment terminates by reason of the Employee's voluntary resignation (but not
as a result of an Involuntary Termination) or as a result of the Employee's
termination for Cause, then the Employee shall not be entitled to receive any
severance pay or benefits under this Agreement.

          (c)  Disability; Death. If the Company terminates the Employee's
               -----------------
employment as a result of the Employee's Disability, or death, then the Employee
shall not be entitled to receive any severance pay or benefits under this
Agreement.

     4.   Release of Claims; Resignation.  The Employee's entitlement to any
          ------------------------------
severance pay or benefits under Section 3(a) is conditioned upon the Employee's
execution and delivery to the Company of (a) a general release of known and
unknown claims in a form satisfactory to the Company and (b) a resignation from
all of the Employee's positions with the Company, including from the Board of
Directors and any committees thereof on which the Employee serves, in a form
satisfactory to the Company.

     5.   Parachute Payments. In the event that any payment or benefit received
          ------------------
or to be received by the Employee pursuant to this Agreement or otherwise
(collectively, the "Payments") would result in a "parachute payment" as
described in section 280G of the Internal Revenue Code of 1986, as amended,
notwithstanding the other provisions of this Agreement, the amount of such
Payments will not exceed the amount which produces the greatest after-tax
benefit to the

                                       2
<PAGE>

Employee. For purposes of the foregoing, the greatest after-tax benefit will be
determined within thirty (30) days of the occurrence of such payment to the
Employee, in the Employee's sole and absolute discretion. If no such
determination is made by the Employee within thirty (30) days of the occurrence
of such payment, the Company will promptly make such determination in a fair and
equitable manner.

     6.   Consulting Services. During the twenty-four (24) months following any
          -------------------
Involuntary Termination for which the Employee receives the severance pay and
benefits described in Section 3(a), the Employee shall be retained by the
Company as an independent contractor to provide consulting services to the
Company at its request for up to eight (8) hours per week. These services shall
include any reasonable requests for information or assistance by the Company,
including, but not limited to, the transition of the Employee's duties. Such
services shall be provided as and when reasonably requested by the Company. For
the actual provision of such services, the Company shall pay to the Employee a
consulting fee of $1,000 per day.
