     as provided in Paragraph 5 then, on or before Employee's last day of
     employment with the Company, the provisions of this Paragraph 7 a. shall
     apply. These same provisions shall apply if Employee terminates his
     employment with the Company without Good Reason.

               (i) SALARY, PERFORMANCE AWARD, AND BONUS PAYMENTS. The Company
          shall pay in a lump sum to Employee at the time of Employee's
          termination (a) an amount

<PAGE>   3

          equal the unpaid salary due to the Employee for services performed
          prior to the date of termination of employment plus (b) such amount of
          Employee's target incentive bonus as has been earned based upon
          fulfilling performance goals, and been accrued but remains unpaid plus
          (c) compensation for unused vacation time. Any and all other rights
          granted to Employee under this Agreement shall terminate as of the
          date of termination.

               (ii) NONCOMPETITION/NONSOLICITATION PERIOD. The provisions of
          Paragraphs 12 and 13 shall, at the option of the Company in its sole
          discretion, continue to apply with respect to Employee for a period of
          six months.

          b. TERMINATION WITHOUT CAUSE. In the event Employee's employment with
     the Company (including its subsidiaries) is terminated by the Company for
     any reason other than for Cause as provided in Paragraph 5 and other than
     as a consequence of Employee's death, disability, or normal retirement
     under the Company's retirement plans and practices, then the following
     provisions apply. These same provisions shall apply if Employee terminates
     his employment with Good Reason as described in Paragraph 6. In addition to
     the amounts stated below, Employee shall be paid an amount equal the unpaid
     salary due to the Employee for services performed prior to the date of
     termination of employment plus compensation for unused vacation time.

               (i) SALARY, PERFORMANCE AWARD, AND BONUS PAYMENTS. The Company
          shall pay to Employee as compensation for services rendered to the
          Company a cash amount equal to one-half (1/2) of the Employee's annual
          base salary as then in effect plus the greater of (x) one-half (1/2)
          the amount of Employee's targeted incentive bonus for the fiscal year
          in which such employment is terminated, or (y) the amount of the
          targeted incentive bonus to which he is entitled but which remains
          unpaid. At the election of the Company, the cash amount referred to in
          this Paragraph 7 (b) (i) may be paid to Employee in one lump sum or in
          periodic installments, without interest, in accordance with the
          regular salary payment practices of the Company, with the first such
          installment to be paid on or before Employee's last day of employment
          with the Company, and no interest shall be paid with respect to any
          amount not paid on the Employee's date of termination.

               (ii) VESTING OF OPTIONS AND RIGHTS. Notwithstanding the vesting
          period provided for in the Stock Incentive Plan and any related stock
          option agreements between the Company and Employee for stock options
          ("options") and stock appreciation rights ("rights") granted Employee
          by the Company, all options and stock appreciation rights that were
          exercisable at the date of termination or within six months thereafter
          shall be immediately exercisable upon termination of employment. In
          addition, Employee will have the right to exercise all such options
          and rights for the shorter of (a) six months following his termination
          of employment or (b) with respect to each option, the remainder of the
          period of exercisability under the terms of the appropriate documents
          that grant such options.

               (iii) BENEFIT PLAN COVERAGE. The Company shall maintain in full
          force and effect for Employee and his dependents for six months after
          the date of termination, all life, health, accident, and disability
          benefit plans and other similar employee benefit plans, programs and
          arrangements in which Employee or his dependents were entitled to
          participate immediately prior to the date of termination, in such
          amounts as were in effect immediately prior to the date of
          termination, provided that such continued participation is possible
          under the general terms and provisions of such benefit plans, programs
          and arrangements. In the event that participation in any benefit plan,
          program or arrangement described above is barred, or any such benefit
          plan, program or arrangement is discontinued or the benefits
          thereunder materially reduced, the Company shall arrange to provide
          Employee and his dependents for six months after the date of
          termination with benefits substantially similar to those that they
          were entitled to receive under such benefit plans, programs and
          arrangements immediately prior to the date of termination.
          Notwithstanding any time period for continued benefits stated in this
          Paragraph 7 (b)(iii), all benefits in this Paragraph 7(b)(iii), will
          terminate on the date that Employee becomes an employee of another
          employer and eligible to participate in the employee benefit plans of
          such other employer. To the extent that Employee was required to
          contribute amounts for the benefits described in this Paragraph
          7(b)(iii), prior to his termination, he shall continue to contribute
          such amounts for such time as these benefits continue in effect after
          termination.

               (iv) SAVINGS AND OTHER PLANS. Except as otherwise more
          specifically provided herein or under the terms of the respective
          plans relating to termination of employment, Employee's active
          participation in any applicable savings, retirement, profit sharing or
          supplemental employee retirement plans or any deferred compensation or
          similar plan of the Company or any of its subsidiaries shall continue
          only through the last day of his employment. All other provisions,
          including any distribution and/or vested rights under such plans,
          shall be governed by the terms of those respective plans.

               (v) NONCOMPETITION/NONSOLICITATION PERIOD. The provisions of
          Paragraphs 12 and 13 shall continue, beyond the time periods set forth
          in such paragraphs, to apply with respect to Employee for six months.
          The noncompetition and nonsolicitation provisions of this Agreement
          shall no longer apply to Employee if the Company fails to pay the
          amounts required under the provisions of Paragraph 7b(i) for an
          uninterrupted 10-day period and such failure is not cured within 10
          days after written notice of such failure is delivered to the Company.

          c. THIS SECTION DOES NOT ADDRESS TERMINATIONS AFTER A CHANGE IN
     CONTROL. The provisions of this Paragraph 7 shall apply if Employee's
     employment is terminated prior to or more than one year after the
     occurrence of a Change of Control (as defined in Paragraph 8). From the
     occurrence of any Change of Control until the first anniversary of such
     Change of Control, the provisions of Paragraph 8 shall apply in place of
     this Paragraph 7, EXCEPT THAT in the event that Employee's employment is
     terminated by Employee after a Change of Control without Good Reason, then
     the provisions of Paragraph 8 shall not apply and the provisions of
     Paragraph 7a shall apply. Termination upon death, and disability are
     covered by Paragraphs 9 and 10 and respectively.

     8. PAYMENT AND OTHER PROVISIONS AFTER CHANGE OF CONTROL.

          a. SALARY, PERFORMANCE AWARD, AND BONUS PAYMENTS. In the event
     Employee's employment with the Company is terminated following the
     occurrence of a Change of Control (other than as a consequence of his death
     or disability) either (i) by the Company for any reason whatsoever or (ii)
     by Employee with Good Reason as provided in Paragraph 6, then all benefits
     under Paragraphs 7 (b) (i), (ii), (iii) and (iv) shall be extended to
     Employee as described in such Paragraphs except that all options and rights
     shall be immediately exercisable.

          b. NONCOMPETITION PERIOD. In the event Employee's employment with the
     Company is terminated following the occurrence of a Change of Control
     either by the Company for any reason whatsoever or by Employee for any
     reason whatsoever, the provisions of Paragraphs 12 and 13 shall be without
     force and effect and shall not apply to Employee.

          c. DEFINITION OF "CHANGE OF CONTROL." For purposes of this Agreement,
     the term "Change of Control" shall mean

               (i) The acquisition, other than from the Company, by any
          individual, entity or group (within the meaning of ss. 13(d)(3) orss.
          14(d)(2) of the Securities Exchange Act of 1934, as amended (the
          "Exchange Act")) of beneficial ownership (within the meaning of Rule
          13d-3 promulgated under the Exchange Act) (any of the foregoing
          described in this Paragraph 8c(i) hereafter a "Person") of 30% or more
          of either (a) the then outstanding shares of Capital Stock of the
          Company (the "Outstanding Capital Stock") or (b) the combined voting
          power of the then outstanding voting securities of the Company
          entitled to vote generally in the election of directors (the "Voting
          Securities"), PROVIDED, HOWEVER, that any acquisition by (x) the
          Company or any of its subsidiaries, or any employee benefit plan (or
          related trust) sponsored or maintained by the Company or any of its
          subsidiaries or (y) any Person that is eligible, pursuant to Rule
          13d-1(b) under the Exchange Act, to file a statement on Schedule 13G
          with respect to its beneficial ownership of Voting Securities, whether
          or not such Person shall have filed a statement on Schedule 13G,
          unless such Person shall have filed a statement on Schedule 13D with
          respect to beneficial ownership of 30% or more of the Voting
          Securities or (z) any corporation with respect to which, following
          such acquisition, more than 60% of, respectively, the then outstanding
          shares of common stock of such corporation and the combined voting
          power of the then outstanding voting securities of such corporation
          entitled to vote generally in the election of directors is then
          beneficially owned, directly or indirectly, by all or substantially
          all of the individuals and entities who were the beneficial owners,
          respectively, of the Outstanding Capital Stock and Voting Securities
          immediately prior to such acquisition in substantially the same
          proportion as their ownership, immediately prior to such acquisition,
          of the Outstanding Capital Stock and Voting Securities, as the case
          may be, shall not constitute a Change of Control; or


<PAGE>   6

               (ii) Individuals who, as of the date hereof, constitute the Board
          (the "Incumbent Board") cease for any reason to constitute at least a
          majority of the Board, provided that any individual becoming a
          director subsequent to the date hereof whose election or nomination
          for election by the Company's shareholders, was approved by a vote of
          at least a majority of the directors then comprising the Incumbent
          Board shall be considered as though such individual were a member of
          the Incumbent Board, but excluding, for this purpose, any such
          individual whose initial assumption of office is in connection with an
          actual or threatened election contest relating to the election of the
          Directors of the Company (as such terms are used in Rule 14a-11 of
          Regulation 14A, or any successor section, promulgated under the
          Exchange Act); or

               (iii) Approval by the shareholders of the Company of a
          reorganization, merger or consolidation (a "Business Combination"), in
          each case, with respect to which all or substantially all holders of
          the Outstanding Capital Stock and Voting Securities immediately prior
          to such Business Combination do not, following such Business
          Combination, beneficially own, directly or indirectly, more than 60%
          of, respectively, the then outstanding shares of common stock and the
          combined voting power of the then outstanding voting securities
          entitled to vote generally in the election of directors, as the case
          may be, of the corporation resulting from Business Combination; or

               (iv) (a) a complete liquidation or dissolution of the Company or
          (b) a sale or other disposition of all or substantially all of the
          assets of the Company other than to a corporation with respect to
          which, following such sale or disposition, more than 60% of,
          respectively, the then outstanding shares of common stock and the
          combined voting power of the then outstanding voting securities
          entitled to vote generally in the election of directors is then owned
          beneficially, directly or indirectly, by all or substantially all of
          the individuals and entities who were the beneficial owners,
          respectively, of the Outstanding Capital Stock and Voting Securities
          immediately prior to such sale or disposition in substantially the
          same proportion as their ownership of the Outstanding Capital Stock
          and Voting Securities, as the case may be, immediately prior to such
          sale or disposition.

     9. TERMINATION BY REASON OF DEATH. If Employee shall die while employed by
the Company both prior to termination of employment and during the effective
term of this Agreement, all Employee's rights under this Agreement shall
terminate with the payment of such amounts of annual Base Salary as have accrued
but remain unpaid and a prorated amount of targeted incentive bonus under the
Company's Management Bonus Program through the month in which his death occurs,
plus three additional months of the fixed salary and targeted bonus. All
benefits under 7 (b)(ii) and (iv) shall be extended to Employee's estate as
described in such paragraphs. In addition, Employee's eligible dependents shall
receive continued benefit plan coverage under Paragraph 7 (b) (iii) for three
months from the date of Employee's death.

     10. TERMINATION BY DISABILITY. Employee's employment hereunder may be
terminated by the Company for disability. In such event, all Employee's rights
under this Agreement shall terminate with the payment of such amounts of annual
Base Salary as have accrued but remain unpaid as of thirtieth (30th) day after
such notice is given EXCEPT that all benefits under Paragraphs 7 (b)(ii), (iii),
and (iv) shall be extended to Employee as described in such paragraphs. For
purposes of this Agreement, "disability" is defined to mean that, as a result of
Employee's incapacity due to physical or mental illness (a) Employee shall have
been absent from his duties as an officer of the Company on a substantially
full-time basis for six (6) consecutive months; and (b) within thirty (30) days
after the Company notifies Employee in writing that it intends to replace him,
Employee shall not have returned to the performance of his duties as an officer
of the Company on a full-time basis.

     11. CERTAIN LIMITATIONS ON REMEDIES. Paragraph 7(b) provides that certain
payments and other benefits shall be received by Employee upon the termination
of Employee by the Company under the


<PAGE>   7

circumstances described therein. It is the intention of this Agreement that if
the Company terminates Employee other than for Cause then the payments and other
benefits set forth in Paragraph 7(b) shall constitute the sole and exclusive
remedies of Employee.

     12. NONCOMPETITION.

          a. At all times during Employee's employment hereunder, and for such
     additional periods beyond the expiration or early termination of this
     Agreement as may otherwise be required under this Agreement in reference to
     this Paragraph 12, Employee shall not, directly or indirectly, engage or
     agree to engage in any business or enterprise or be employed by or agree to
     be employed by any business or enterprise (a "Competitor"), whether as
     owner, operator, shareholder, director, partner, creditor, employee,
     consultant, agent or in any capacity whatsoever, that manufactures products
     designed to compete directly with products of the Company or markets such
     products anywhere in the world where the Company (i) is engaged in business
     or (ii) has evidenced an intention of engaging in business. For purposes of
     this Paragraph, the parties hereto acknowledge and agree that Concurrent
     Computer Corporation is a Competitor. Employee acknowledges that he has
     read the foregoing and agrees that the nature of the geographical
     restrictions are reasonable given the international nature of the Company's
     business.

          b. In the event that these geographical or temporal restrictions are
     judicially determined to be unreasonable, the parties agree that these
     restrictions shall be judicially reformed to the maximum restrictions which
     are reasonable.

          c. Notwithstanding the provisions of the preceding Paragraph 12a,
     Employee may accept employment with a company that would be deemed to be a
     Competitor of the Company so long as (i) the Competitor has had annual
     revenues of at least $1 billion in each of the prior two fiscal years, (ii)
     the Competitor's revenues for products and maintenance in direct
     competition with the Company does not exceed 50% of its total revenues and
     (iii) Employee's responsibilities are solely for divisions or subsidiaries
     of the Competitor that do not compete with the Company.

     13. NONSOLICITATION OF EMPLOYEES AND CUSTOMERS. At all times during
Employee's employment hereunder, for six months after termination or expiration
of this Agreement, and for such additional periods as may otherwise be required
under this Agreement in reference to this Paragraph 13, Employee shall not,
directly or indirectly, for himself or for any other person, firm, corporation,
partnership, association or other entity (a) attempt to employ, employ or enter
into any contractual arrangement with any employee or former employee of the
Company, its affiliates, subsidiaries or predecessors in interest, unless such
employee or former employee has not been employed by the Company, its
affiliates, subsidiaries or predecessors in interest during the twelve months
prior to Employee's attempt to employ him, or (b) call on or solicit any of the
actual or targeted prospective customers of the Company or its affiliates,
subsidiaries or predecessors in interest with respect to any matters related to
or competitive with the business of the Company.

     14. CONFIDENTIALITY.

          a. NONDISCLOSURE. Employee acknowledges and agrees that the
     Confidential Information (as defined below) is a valuable, special and
     unique asset of the Company's business. Accordingly, except in connection
     with the performance of his duties hereunder, Employee shall not at any
     time during or subsequent to the term of his employment hereunder disclose,
     directly or indirectly, to any person, firm, corporation, partnership,
     association or other entity any proprietary or confidential information
     relating to the Company or any information concerning the Company's
     financial condition, business line, business strategy or prospects, the
     Company's customers, the design, research, development, manufacture,
     marketing or sale of the Company's products, or the Company's methods of
     operating its business, or intellectual property of any kind, which shall
     include, without limitation, inventions, improvements, discoveries,
     creations, computer programs, computer hardware, design specifications,
     concepts, formulas, trade secrets, ideas, processes, know-how, methods,
     proprietary data, software code, source code, products, future products,
     techniques, any and all derivative works therefrom and any and all patents
     and copyrights therein or any improvements thereof (collectively
     "Confidential Information"). Confidential Information shall not include
     information which, at the time of disclosure, is known or available to the
     general public by publication or otherwise through no act or failure to act
     on the part of Employee.

          b. RETURN OF CONFIDENTIAL INFORMATION. Upon termination of Employee's
     employment, for whatever reason and whether voluntary or involuntary, or at
     any time at the request of the Company, Employee shall promptly return all
     Confidential Information in the possession or under the control of Employee
     to the Company and shall not retain any copies or other reproductions or
     extracts thereof. Employee shall at any time at the request of the Company
     destroy or have destroyed all memoranda, notes, reports, and documents,
     whether in "hard copy" form or as stored on magnetic or other media, and
     all copies and other reproductions and extracts thereof, prepared by
     Employee and shall provide the Company with a certificate that the
     foregoing materials have in fact been returned or destroyed.

          c. BOOKS AND RECORDS. All books, records and accounts whether prepared
     by Employee or otherwise coming into Employee's possession, shall be the
     exclusive property of the Company and shall be returned immediately to the
     Company upon termination of Employee's employment hereunder or upon the
     Company's request at any time.

     15. INJUNCTION/SPECIFIC PERFORMANCE SETOFF. Employee acknowledges that a
breach of any of the provisions of Paragraphs 12, 13 and 14 hereof would result
in immediate and irreparable injury to the Company which cannot be adequately or
reasonably compensated at law. Therefore, Employee agrees that the Company shall
be entitled, if any such breach shall occur or be threatened or attempted, to a
decree of specific performance and to a temporary and permanent injunction,
without the posting of a bond, enjoining and restraining such breach by Employee
or his agents, either directly or indirectly, and that such right to injunction
shall be cumulative to whatever other remedies for actual damages to which the
Company is entitled. Employee further agrees that the Company may set off
against or recoup from any amounts due under this Agreement to the extent of any
losses incurred by the Company as a result of

any breach by Employee of the provisions of Paragraphs 12, 13 and 14 hereof.
Employee further acknowledges that the Company may have additional remedies set
forth in other agreements that may be in effect between Employee and the Company
(including without limitation a Stock Option Agreement between Employee and the
Company) that are available to the Company in the event of a breach of any or
all of the provisions of Paragraphs 12, 13 or 14 and that nothing herein shall
be deemed a waiver of such remedies set forth in such other agreements.

     16. SEVERABILITY. Any provision in this Agreement that is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
only to the extent of such prohibition or unenforceability without invalidating
or affecting the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

     17. SUCCESSORS. This Agreement shall be binding upon Employee and inure to
his and his estate's benefit, and shall be binding upon and inure to the benefit
of the Company and any permitted successor of the Company. Neither this
Agreement nor any rights arising hereunder may be assigned or pledged by:
Employee or anyone claiming through Employee; or by the Company, except to any
corporation which is the successor in interest to the Company by reason of a
merger, consolidation or sale of substantially all of the assets of the Company.
The foregoing sentence shall not be deemed to have any effect upon the rights of
Employee upon a Change of Control.

     18. NOTICES. Any notice required or permitted to be given hereunder shall
be written and sent by registered or certified mail, telecommunicated or hand
delivered at the address set forth herein or to any other address of which

between the parties hereto on the subject matter hereof and may not be modified
without the written agreement of both parties hereto.

shall not be construed as a general waiver by such party.

     21. COUNTERPARTS. This Agreement may be executed in counterparts, each of
which shall be deemed an original and both of which together shall constitute a
single agreement.

     22. INTERPRETATION. In the event of a conflict between the provisions of
this Agreement and any other agreement or document defining rights and duties of
Employee or the Company upon Employee's termination, the rights and duties set
forth in this Agreement shall control. This Section 22 is not intended to: waive
or amend the requirement regarding May 6, 1998 as described in Section 1a of the
Non-Statutory Stock Option Agreement dated September 4, 1998 between Employee
and the Company; or reduce Employee's rights regarding options' exercisability
on termination of employment to the extent such rights are more favorable under
any option agreement or option plan.
