interfere with the rendition of such services either directly or indirectly,
without the prior written consent of the Board; provided that nothing herein
shall preclude Executive, (i) subject to the prior approval of the Board, from
accepting appointment to or continue to serve on any board of directors or
trustees of any business corporation or any charitable organization or (ii) from
participating in charitable activities or managing personal investments;

expenses incurred by Executive in the performance of Executive's duties
hereunder shall be reimbursed by the Company in accordance with Company
policies.

          7. Termination. The Employment Term and Executive's employment
hereunder may be terminated by either party at any time and for any reason;
provided that Executive will be required to give the Company at least 30 days

               (i) The Employment Term and Executive's employment hereunder
shall terminate upon Executive's death and may be terminated by the Company if

Disability, except as set forth in this Section 7(b)(ii), Executive shall have
no further rights to any compensation or any other benefits under this
Agreement.

event which constitutes Good Reason.



                                                                               4


               (iii) If Executive's employment is terminated by the Company
without Cause (other than by reason of death or Disability) or if Executive
resigns for Good Reason, Executive shall be entitled to receive:

                    (A) the Accrued Rights;

                    (B) a pro rata portion of any Annual Bonus, if any, that
     Executive would have been entitled to receive pursuant to Section 4 hereof
     in such year based upon the percentage of the fiscal year that shall have
     elapsed through the date of Executive's termination of employment, payable
     when such Annual Bonus would have otherwise been payable had Executive's
     employment not terminated, and

                    (C) subject to Executive's continued compliance with the

     the twelve month period after the date of such termination, in accordance
     with the Company's usual payroll practice; provided that the aggregate
     amount described in this clause (C) shall be reduced by the present value
     of any other cash severance or termination benefits payable to Executive
     under any other plans, programs or arrangements of the Company or its
     affiliates.

          Following Executive's termination of employment by the Company without
Cause (other than by reason of Executive's death or Disability) or by
Executive's resignation for Good Reason, except as set forth in this Section
7(c)(iii), Executive shall have no further rights to any compensation or any
other benefits under this Agreement.

                    d. Continued Employment Beyond the Expiration of the
Employment Term. Unless the parties otherwise agree in writing, continuation of
Executive's employment with the Company beyond the expiration of the Employment
Term shall be deemed an employment at-will and shall not be deemed to extend any
of the provisions of this Agreement and Executive's employment may thereafter be
terminated at will by either Executive or the Company; provided that the
provisions of Sections 8, 9 and 10 of this Agreement shall survive any
termination of this Agreement or Executive's termination of employment
hereunder.

                    e. Notice of Termination. Any purported termination of
employment by the Company or by Executive (other than due to Executive's death)
shall be communicated by written Notice of Termination to the other party hereto
in accordance with Section 11(g) hereof. For purposes of this Agreement, a
"Notice of Termination" shall mean a notice which shall indicate the specific
termination provision in this Agreement relied upon and shall set forth in
reasonable detail the facts and circumstances claimed to provide a basis for
termination of employment under the provision so indicated.

                    f. Board/Committee Resignation. Upon termination of
Executive's employment for any reason, Executive agrees to resign, as of the
date of such termination and to the extent applicable, from the Board (and any
committees thereof) and the Board of Directors (and any committees thereof) of
any of the Company's affiliates.



                                                                               5


          8. Non-Competition.

                    a. Executive acknowledges and recognizes the highly
competitive nature of the businesses of the Company and its affiliates and
accordingly agrees as follows:

          (1) During the Employment Term and, for a period of one year following
the date Executive ceases to be employed by the Company (the "Restricted
Period"), Executive will not, whether on Executive's own behalf or on behalf of
or in conjunction with any person, firm, partnership, joint venture,
association, corporation or other business organization, entity or enterprise
whatsoever ("Person"), directly or indirectly solicit or assist in soliciting in
competition with the Company, the business of any client or prospective client:

                    (i)  with whom Executive had personal contact or dealings on
                         behalf of the Company during the one year period
                         preceding Executive's termination of employment;

                    (ii) with whom employees reporting to Executive have had
                         personal contact or dealings on behalf of the Company
                         during the one-year immediately preceding the
                         Executive's termination of employment; or

                    (iii) for whom Executive had direct or indirect
                         responsibility during the one year period immediately
                         preceding Executive's termination of employment.

          (2) During the Restricted Period, Executive will not directly or
indirectly:

                    (i)  engage in any business that competes with the business
                         of the Company or its affiliates (including, without
                         limitation, businesses which the Company or its
                         affiliates have specific plans to conduct in the future
                         and as to which Executive is aware of such planning) (a
                         "Competitive Business");

                    (ii) enter the employ of, or render any services to, any
                         Person (or any division or controlled or controlling
                         affiliate of any Person) who or which engages in a
                         Competitive Business;

                    (iii) acquire a financial interest in, or otherwise become
                         actively involved with, any Competitive Business,
                         directly or indirectly, as an individual, partner,
                         shareholder, officer, director, principal, agent,
                         trustee or consultant; or

                    (iv) interfere with, or attempt to interfere with, business
                         relationships (whether formed before, on or after the
                         date of this Agreement) between the Company or any of
                         its affiliates and customers,



                                                                               6


                         clients, suppliers partners, members or investors
                         of the Company or its affiliates.

          (3) Notwithstanding anything to the contrary in this Agreement,
Executive may directly or indirectly own, solely as an investment, securities of
any Person engaged in the business of the Company or its affiliates which are
publicly traded on a national or regional stock exchange or on the
over-the-counter market if Executive (i) is not a controlling person of, or a
member of a group which controls, such person and (ii) does not, directly or
indirectly, own 5% or more of any class of securities of such Person.

          (4) During the Restricted Period, Executive will not, whether on
Executive's own behalf or on behalf of or in conjunction with any Person,
directly or indirectly:

                    (i)  solicit or encourage any employee of the Company or its
                         affiliates to leave the employment of the Company or
                         its affiliates (other than as a result of a general
                         advertisement of employment made by Executive's
                         subsequent employer or business, not directed at any
                         such employee); or

                    (ii) hire any such employee who was employed by the Company
                         or its affiliates as of the date of Executive's
                         termination of employment with the Company or who left
                         the employment of the Company or its affiliates
                         coincident with, or within one year prior to or after,
                         the termination of Executive's employment with the
                         Company.

          (5) During the Restricted Period, Executive will not, directly or
indirectly, solicit or encourage to cease to work with the Company or its
affiliates any consultant then under contract with the Company or its
affiliates.

                    b. It is expressly understood and agreed that although
Executive and the Company consider the restrictions contained in this Section 8
to be reasonable, if a final judicial determination is made by a court of
competent jurisdiction that the time or territory or any other restriction
contained in this Agreement is an unenforceable restriction against Executive,
the provisions of this Agreement shall not be rendered void but shall be deemed
amended to apply as to such maximum time and territory and to such maximum
extent as such court may judicially determine or indicate to be enforceable.
Alternatively, if any court of competent jurisdiction finds that any restriction
contained in this Agreement is unenforceable, and such restriction cannot be
amended so as to make it enforceable, such finding shall not affect the
enforceability of any of the other restrictions contained herein.

          9. Confidentiality; Intellectual Property.



                                                                               7


                    a. Confidentiality.

Executive by a third party without breach of any confidentiality obligation; or
(c) required by law to be disclosed; provided that Executive shall give prompt
written notice to the Company of such requirement, disclose no more information

and diaries that do not contain any Confidential Information; and (z) notify and
fully cooperate with the Company regarding the delivery or destruction of any
other Confidential Information of which Executive is or becomes aware.

                    b. Intellectual Property.



                                                                               8


               (i) If Executive has created, invented, designed, developed,
contributed to or improved any works of authorship, inventions, intellectual
property, materials, documents or other work product (including without
limitation, research, reports, software, databases, systems, applications,
presentations, textual works, content, or audiovisual materials) ("Works"),
either alone or with third parties, prior to Executive's employment by the
Company, that are relevant to or implicated by such employment ("Prior Works"),
Executive hereby grants the Company a perpetual, non-exclusive, royalty-free,
worldwide, assignable, sublicensable license under all rights and intellectual
property rights (including rights under patent, industrial property, copyright,
trademark, trade secret, unfair competition and related laws) therein for all
purposes in connection with the Company's current and future business. A list of
all such Works as of the date hereof is attached hereto as Exhibit A.

               (ii) If Executive creates, invents, designs, develops,
contributes to or improves any Works, either alone or with third parties, at any
time during Executive's employment by the Company and within the scope of such
employment and/or with the use of any the Company resources ("Company Works"),
Executive shall promptly and fully disclose same to the Company and hereby
irrevocably assigns, transfers and conveys, to the maximum extent permitted by
applicable law, all rights and intellectual property rights therein (including
rights under patent, industrial property, copyright, trademark, trade secret,
unfair competition and related laws) to the Company to the extent ownership of
any such rights does not vest originally in the Company.

               (iii) Executive agrees to keep and maintain adequate and current
written records (in the form of notes, sketches, drawings, and any other form or
media requested by the Company) of all Company Works. The records will be
available to and remain the sole property and intellectual property of the
Company at all times.

               (iv) Executive shall take all requested actions and execute all
requested documents (including any licenses or assignments required by a
government contract) at the Company's expense (but without further remuneration)
to assist the Company in validating, maintaining, protecting, enforcing,
perfecting, recording, patenting or registering any of the Company's rights in
the Prior Works and Company Works. If the Company is unable for any other reason
to secure Executive's signature on any document for this purpose, then Executive
hereby irrevocably designates and appoints the Company and its duly authorized
officers and agents as Executive's agent and attorney in fact, to act for and in
Executive's behalf and stead to execute any documents and to do all other
lawfully permitted acts in connection with the foregoing.

               (v) Executive shall not improperly use for the benefit of, bring
to any premises of, divulge, disclose, communicate, reveal, transfer or provide

information or intellectual property relating to a former employer or other
third party without the prior written permission of such third party. Executive
hereby indemnifies, holds harmless and agrees to defend the Company and its
officers, directors, partners, employees, agents and representatives from any
breach of the foregoing covenant. Executive shall comply with all relevant
policies and guidelines of the Company, including regarding the protection of
confidential information and intellectual



                                                                               9


property and potential conflicts of interest. Executive acknowledges that the
Company may amend any such policies and guidelines from time to time, and that
Executive remains at all times bound by their most current version.

               (vi) The provisions of Section 9 shall survive the termination of
Executive's employment for any reason.

          10. Specific Performance. Executive acknowledges and agrees that the
Company's remedies at law for a breach or threatened breach of any of the
provisions of Section 8 or Section 9 would be inadequate and the Company would
suffer irreparable damages as a result of such breach or threatened breach. In
recognition of this fact, Executive agrees that, in the event of such a breach
or threatened breach, in addition to any remedies at law, the Company, without
posting any bond, shall be entitled to cease making any payments or providing
any benefit otherwise required by this Agreement and obtain equitable relief in
the form of specific performance, temporary restraining order, temporary or
permanent injunction or any other equitable remedy which may then be available.

          11. Miscellaneous.

to conflicts of laws principles thereof.

entire understanding of the parties with respect to the employment of Executive
by the Company. There are no restrictions, agreements, promises, warranties,
covenants or undertakings between the parties with respect to the subject matter
herein other than those expressly set forth herein. This Agreement may not be
altered, modified, or amended except by written instrument signed by the parties
hereto.

                    c. No Waiver. The failure of a party to insist upon strict
adherence to any term of this Agreement on any occasion shall not be considered
a waiver of such party's rights or deprive such party of the right thereafter to
insist upon strict adherence to that term or any other term of this Agreement.

                    d. Severability. In the event that any one or more of the
provisions of this Agreement shall be or become invalid, illegal or
unenforceable in any respect, the validity, legality and enforceability of the
