documentation of such expenses.

            (f) The Company shall deduct from any payments to be made by it to

SECTION 4. POSITION AND DUTIES.

            (a) During the Employment Period, the Executive shall initially
serve as Senior Vice President Marketing and Strategy, and shall report to the
President and CEO. The Executive shall perform his duties at the Company's

act in a manner consistent with the best interests of the Company and its
Subsidiaries.

            (b) During the Employment Period, the Executive shall devote his
best efforts and full working time, attention and energies to the performance of
his duties and responsibilities under this Agreement (except for vacations to
which he is entitled pursuant to Section 3(a) and except for illness or
incapacity). During the Employment Period, the Executive shall not engage in any
business activity which, in the reasonable judgment of the Board (excluding the
Executive if he should be a member of the Board at the time of such
determination), conflicts with the


                                     - 2 -
<PAGE>
duties of the Executive hereunder, whether or not such activity is pursued for
gain, profit or other pecuniary advantage.

SECTION 5. TERMINATION.

            (a) Termination Date. The Executive's employment under this
Agreement shall terminate upon the earliest to occur (the date of such
occurrence being the "Termination Date") of (i) the effective date of the
Executive's resignation (a "Resignation"), (ii) the Executive's death or
Disability (an "Involuntary Termination"), (iv) the effective date of a
termination of the Executive's employment for Cause by the Board or the
President of the Company (a "Termination for Cause"), and (v) the effective date
of a termination of the Executive's employment by the Board for reasons that do
not constitute Cause (a "Termination Without Cause"). The effective date of a
Resignation shall be as determined under Section 5(b); the effective date of an
Involuntary Termination shall be the date of death or, in the event of a
Disability, the date specified in a notice delivered to the Executive by the
Company; and the effective date of a Termination for Cause or a Termination
Without Cause shall be the date specified in a notice delivered to the Executive
by the Company of such termination.

            (b) Resignation. The Executive shall give the Company at least 30
days' prior written notice of a Resignation, with the effective date of such
Resignation specified therein. The Company may, in its discretion, accelerate
the effective date of the Resignation.

SECTION 6. EFFECT OF TERMINATION; SEVERANCE.

            (a) In the event of a Termination Without Cause, the Executive or
his beneficiaries or estate shall have the right to receive the following:

                  (i) the unpaid portion of the Base Salary, computed on a pro
      rata basis to the Termination Date;

                  (ii) the unpaid portion of the Base Salary for the period
      beginning on the Termination Date and ending thirty (30) days from the
      Termination Date., payable in the same amounts and at the same intervals
      as the Base Salary was paid immediately prior to the Termination Date;
      provided, however, that in the event of a breach by the Executive of
      Section 7, 8, 9 or 10 on or after the Termination Date, the provisions of
      Section 12 shall apply;

                  (iii) reimbursement for any expenses for which the Executive
      shall not have been previously reimbursed, as provided in Section 3(c);
      and

                  (iv) the portion of any bonus payable in accordance with
      Section 3(b) for the calendar year in which such termination occurs, pro
      rated through the date of such termination on a per diem basis.

            (b) In the event of a Termination for Cause, an Involuntary
Termination or a Resignation, the Executive or his beneficiaries or estate shall
have the right to receive the following:


                                     - 3 -
<PAGE>
                  (i) the unpaid portion of the Base Salary, computed on a pro
      rata basis to the Termination Date; and

                  (ii) reimbursement for any expenses for which the Executive
      shall not have been previously reimbursed, as provided in Section 3(c).

            (c) Upon any termination, neither the Executive nor his
beneficiaries or estate shall have any further rights under this Agreement or
any rights arising out of this Agreement other than as provided in Sections 6(a)
and (b) above.

SECTION 7. NONDISCLOSURE AND NONUSE OF CONFIDENTIAL INFORMATION.

            The Executive will not disclose or use at any time, either during
the Employment Period and for a period of five years thereafter, any
Confidential Information of which the Executive is or becomes aware, whether or
not such information is developed by him, except to the extent that such
disclosure or use is directly related to and required by the Executive's
performance of duties assigned to the Executive by the Company.

SECTION 8. INVENTIONS AND PATENTS.

            The Executive agrees that all Work Product belongs to the Company.
The Executive will promptly disclose such Work Product to the Board and perform
all actions reasonably requested by the Board (whether during or after the
Employment Period) to establish and confirm such ownership (including, without
limitation, the execution and delivery of assignments, consents, powers of
attorney and other instruments) and to provide reasonable assistance to the
Company in connection with the prosecution of any applications for patents,
trademarks, trade names, service marks or reissues thereof or in the prosecution
or defense of interferences relating to any Work Product.

SECTION 9. NON-COMPETE, NON-SOLICITATION, NON-DISPARAGEMENT.

            The Executive acknowledges and agrees with the Company that, during
the course of the Executive's employment with the Company, the Executive has had
and will continue to have the opportunity to develop relationships with existing
employees, customers and other business associates of the Company and its
Subsidiaries which relationships constitute goodwill of the Company, and the
Company would be irreparably damaged if the Executive were to take actions that
would damage or misappropriate such goodwill. Accordingly, the Executive agrees
as follows:

            (a) The Executive acknowledges that the Company currently conducts
the Subject Business throughout the world (the "Territory"). Accordingly, during
the term hereof and until the first anniversary of the Termination Date (the
"Non-Compete Period"), the Executive shall not, directly or indirectly, enter
into, engage in, assist, give or lend funds to or otherwise finance, be employed
by or consult with, or have a financial or other interest in, any business which
competes or could, in the reasonable judgment of the Board, be deemed to be in
competition with, at the time in question, the Company within the Territory,
whether for or by himself or as an independent contractor, agent, stockholder,
partner or joint venturer for any other Person. To the extent that the covenant
provided for in this Section 9(a) may later be deemed by a court to


                                     - 4 -
<PAGE>
be too broad to be enforced with respect to its duration or with respect to any
particular activity or geographic area, the court making such determination
shall have the power to reduce the duration or scope of the provision, and to
add or delete specific words or phrases to or from the provision. The provision
as modified shall then be enforced.

            (b) Notwithstanding the foregoing, the aggregate ownership by the
Executive of no more than two percent (on a fully-diluted basis) of the
outstanding equity securities of any Person, which securities are traded on a
national or foreign securities exchange, quoted on the NASDAQ stock market or
other automated quotation system, and which Person competes with the Company (or
any part thereof) within the Territory, shall not be deemed to be a violation of
Section 9(a). In the event that any Person in which the Executive has any
financial or other interest directly or indirectly enters into a business during
the Non-Compete Period that competes with the Company within the Territory, the
Executive shall divest all of his interest (other than as permitted to be held
pursuant to the first sentence of this Section 8(b)) in such Person within 15
days after such Person enters into such business that competes with the Company
within the Territory.

            (c) The Executive covenants and agrees that, during the period
commencing with the Effective Date and ending on the first anniversary of the
date on which the Executive ceases to be employed by the Company for any reason
whatsoever, the Executive will not, directly or indirectly, either for himself
or for any other Person (A) solicit any employee of the Company or any of its
Subsidiaries to terminate his or her employment with the Company or any of its
Subsidiaries or employ any such individual during his or her employment with the
Company or any of its Subsidiaries and for a period of one year after such
individual terminates his or her employment with the Company or any of its
Subsidiaries, (B) solicit any customer of the Company or any of its Subsidiaries
to purchase or distribute information, products or services of or on behalf of
the Executive or such other Person that are competitive with the information,
products or services provided by the Company or any of its Subsidiaries, or (c)
take any action that may cause injury to the relationships between the Company
or any of its Subsidiaries or any of their employees and any lessor, lessee,
vendor, supplier, customer, distributor, employee, consultant or other business
associate of the Company or any of its Subsidiaries as such relationship relates
to the Company's or any of its Subsidiaries' conduct of their business.

            (d) The Executive understands that the foregoing restrictions may
limit his ability to earn a livelihood in a business which is competitive with
the business of the Company and any of its Subsidiaries, but he nevertheless
believes that he has received and will receive sufficient consideration and
other benefits as an employee of the Company and as otherwise provided hereunder
or as described in the recitals hereto to clearly justify such restrictions
which, in any event (given his education, skills and ability), the Executive
does not believe would prevent him from otherwise earning a living.


SECTION 10. DELIVERY OF MATERIALS UPON TERMINATION OF EMPLOYMENT.

            The Executive shall deliver to the Company at the termination of the
Employment Period or at any time the Company may request all memoranda, notes,
plans, records, reports,


                                     - 5 -
<PAGE>
computer tapes and software and other documents and data (and copies thereof)
relating to the Confidential Information, Work Product or the Subject Business
which he may then possess or have under his control regardless of the location
or form of such material and, if requested by the Company, will provide the
Company with written confirmation that all such materials have been delivered to
the Company.

SECTION 11. INSURANCE.

            The Company may, for its own benefit, maintain "keyman" life and
disability insurance policies covering the Executive. The Executive will
cooperate with the Company and provide such information or other assistance as
the Company may reasonably request in connection with the Company obtaining and
maintaining such policies.

SECTION 12. ENFORCEMENT.

            Because the Executive's services are unique and because the
Executive has access to Confidential Information and Work Product, the parties
hereto agree that money damages would be an inadequate remedy for any breach of
this Agreement. Therefore, in the event of a breach or threatened breach of this
Agreement, the Company or its successors or assigns may, in addition to other
rights and remedies existing in their favor, apply to any court of competent
jurisdiction for specific performance and/or injunctive or other relief in order
to enforce, or prevent any violations of, the provisions hereof (without posting
a bond or other security). In addition to the foregoing, and not in any way in
limitation thereof, or in limitation of any right or remedy otherwise available
to the Company, if the Executive violates any provision of the foregoing
Sections 7, 8, 9 or 10, any payments then or thereafter due from the Company to
the Executive pursuant to Section 6(a)(ii) shall be terminated forthwith and the
Company's obligation to pay and the Executive's right to receive such payments
shall terminate and be of no further force or effect, in each case without
limiting or affecting the Executive's obligations under such Sections 7, 8, 9 or
10or the Company's other rights and remedies available at law or equity.

SECTION 13. REPRESENTATIONS.

            Each party hereby represents and warrants to the other party that
(a) the execution, delivery and performance of this Agreement by such party does
not and will not conflict with, breach, violate or cause a default under any
agreement, contract or instrument to which such party is a party or any
judgment, order or decree to which such party is subject, and (b) upon the
execution and delivery of this Agreement by such party, this Agreement will be a
valid and binding obligation of such party, enforceable in accordance with its
terms, except as enforcement hereof may be limited by any applicable bankruptcy,
reorganization, insolvency or other laws affecting creditors rights generally or
by general principles of equity. In addition, the Executive represents and
warrants to the Company that the Executive is not a party to or bound by any
employment agreement, consulting agreement, non-compete agreement,
confidentiality agreement or similar agreement with any other Person. The
Company and the Executive hereby terminate all existing employment or consulting
agreements between them, if any, to the extent such agreements may be in effect
after the date hereof.

other jurisdiction. Notwithstanding the foregoing, if such provision could be
more narrowly drawn so as not to be invalid, prohibited or unenforceable in such
jurisdiction, it shall, as to such jurisdiction, be so narrowly drawn, without
