Company, the Employee agrees that he shall not knowingly become involved in a
conflict of interest with the Company, or upon discovery thereof, allow such a
conflict to continue. The Employee further agrees to disclose to the Company,
promptly after discovery, any facts or circumstances which might involve a
conflict of interest with the Company.

         7.2      The Company and the Employee recognize that it is impossible
to provide an exhaustive list of actions or interests which constitute a
"conflict of interest." Moreover, the Company and the Employee recognize that
there are many borderline situations. In some instances, full disclosure of
facts by the Employee to the Company is all that is necessary to enable the
Company to protect its interests. In others, if no improper motivation appears
to exist and the Company's interests have not suffered, prompt elimination of
the outside interest will suffice. In still others, it may be necessary for the
Company to terminate the employment relationship. The Company and the Employee
agree that the Company's determination as to whether or not a conflict of
interest exists shall be conclusive. The Company reserves the right to take such
action as, in its judgment, will end the conflict of interest.

         7.3      In this connection, it is agreed that any direct or indirect
interest in, connection with or benefit from any outside activities,
particularly commercial activities, which interest might in any way adversely
affect the Company or its Affiliates, involves a possible conflict of interest.

or might arise, and which should be reported immediately to the Company,
include, but are not limited to, the following:

inventions, both in the United States and all foreign countries, which
assistance shall include, but shall not be limited to, the execution of all
lawful oaths and all assignment documents requested by the Company or its
nominee in connection with the preparation, prosecution, issuance or enforcement
of any applications for United States or foreign letters patent, including
divisions, continuations, continuations-in-part, reissues and/or extensions
thereof, and any application for the registration of such names and service
marks.

         10.3     In the event the Employee creates, during the Employee's
employment by the Company, any original work of authorship fixed in any tangible
medium of expression which is the subject matter of copyright (such as,
videotapes, written presentations on acquisitions, computer programs, drawings,
maps, architectural renditions, models, manuals, brochures or the like) relating
to the Company's business, products or services, whether such work is created
solely by the Employee or jointly with others, the Company shall be deemed the
author of such work if the work is prepared by the Employee within the scope of
his employment; or, if the work is not prepared by the Employee within the scope
of his employment but is specially ordered by the Company as a contribution to a
collective work, as a part of a motion picture or other audiovisual work, as a
translation, as a supplementary work, as a compilation or as an instructional
text, then the work shall be considered to be a work made for hire, and the
Company shall be the author of such work. If such work is neither prepared by
the Employee within the scope of his employment nor a work specially ordered and
deemed to be a work made for hire, then the Employee hereby agrees to sell,
transfer, assign and convey, and by these presents, does sell, transfer, assign
and convey, to the Company all of the Employee's worldwide right, title and
interest in and to such work and all rights of copyright therein. The Employee
agrees to assist the Company and its Affiliates, at all times, until the Date of
Termination and at all times thereafter, in the protection of the Company's
worldwide right, title and interest in and to such work and all rights of
copyright therein, which assistance shall include, but shall not be limited to,
the execution of all documents requested by the Company or its nominee and the
execution of all lawful oaths and applications for registration of copyright in
the United States and foreign countries.

11.      Employee's Non-Competition Obligation.

         11.1     Until the Date of Termination, and (a) in the event of a
termination under Section 6.1 hereof for a period of one year following the Date
of Termination or (b) in the event of a termination under Section 6.2 hereof for
a period equal to the period for which payments are made to the Employee under
Section 6.2.4 hereof, the Employee shall not, acting alone or in conjunction
with others, directly or indirectly, in any of the business territories in which
the Company or any of its Affiliates is as of the Date of Termination conducting
business, invest or engage, directly or indirectly, in any business which is
competitive with that of the Company as of the Date of Termination or accept
employment with or render services to such a competitor as a director, officer,

                                       10

agent, employee or consultant, or take any action inconsistent with the
fiduciary relationship of an employee to his employer; provided, however, that
the beneficial ownership by the Employee of up to three percent of the voting
stock of any corporation subject to the periodic reporting requirements of the
Exchange Act shall not violate this Section 11.1.

         11.2     In addition to the other obligations agreed to by the Employee
in this Agreement, the Employee agrees that until the Date of Termination, and
(a) in the event of a termination under Section 6.1 hereof for a period of one
year following the Date of Termination or (b) in the event of a termination
under Section 6.2 hereof for a period equal to the period for which payments are
made to the Employee under Section 6.2.4 hereof, he shall not at any time,
directly or indirectly, (i) induce, entice or solicit any employee of the
Company to leave his employment, (ii) contact, communicate or solicit any
customer or acquisition prospect of the Company derived from any customer list,
customer lead, mail, printed matter or other information secured from the
Company or its present or past employees or (iii) in any other manner use any
customer lists or customer leads, mail, telephone numbers, printed material or
other information of the Company relating thereto.

         11.3     The parties hereto acknowledge and agree that (i) the
agreements and covenants set forth in this Section 11 are being made for good
and valuable consideration, the receipt and sufficiency of which is
acknowledged; (ii) the covenants contained in this Section 11 are an important
aspect of this Agreement, and the Company would not have entered into this
Agreement absent the inclusion of this Section 11; and (iii) the restrictions
imposed in this Section 11, including the geographic area and duration of the
covenants made herein, are reasonable and necessary to protect the Company. If
the Employee breaches or indicates an intention to breach any term or provision
of this Section 11, the parties hereto agree that the Company shall be entitled
to the right of both temporary and permanent injunctive relief and/or specific
performance. The right of the Company to such relief shall not be construed to
prevent the Company from pursuing, either consecutively or concurrently, any and
all other legal or equitable remedies available to it for such breach or
threatened breach, specifically including, without limitation, the recovery of
monetary damages. If any court determines that any provision of this Section 11,
or any part thereof, is unenforceable because of the duration or geographic
scope of such provision, the parties hereto agree that such court shall have the
power to reduce the duration or geographic scope of such provision, as the case
may be, and the parties hereto agree to request the court to exercise such
power, and, in its amended form, such provision shall then be enforceable and
shall be enforced.

the benefit of the Company, its successors, legal representatives and assigns,

any written agreement unless signed by an officer of the Company who is
expressly authorized by the Company to execute such document.

         12.5     Enforceability. If any provision of this Agreement or
application thereof to anyone or under any circumstances shall be determined to
be invalid or unenforceable, such invalidity or unenforceability shall not
affect any other provisions or applications of this Agreement which can be given
effect without the invalid or unenforceable provision or application.

         12.6     Jurisdiction; Arbitration. The laws of the State of Delaware
shall govern the interpretation, validity and effect of this Agreement without
regard to the place of execution or the place for performance thereof. Except

jurisdiction thereof, which judgment shall be binding upon the parties hereto.

         12.7     Injunctive Relief. The Company and the Employee agree that a
breach of any term of this Agreement by the Employee would cause irreparable
damage to the Company and that, in the event of such breach, the Company shall
have, in addition to any and all remedies of law, the right to any injunction,
specific performance and other equitable relief to prevent or to redress the
violation of the Employee's duties or responsibilities hereunder.
