                  5. Non-competition. During the Agreement Term, including any

of the twelfth month following such date of termination or resignation, which
severance pay shall be paid commencing with such date of termination or
resignation at the times and in the amounts such Base Salary would have been
paid if Executive had not been terminated or resigned. Executive shall also
receive his bonus on a pro-rated basis through his last day of employment.
Except as set forth below, during such] twelve month period, Executive shall
also continue to participate in and receive the benefits and perquisites

pursuant to this Section 7(e) to pay severance, bonus, and to continue benefits
and perquisites shall cease and Executive's rights thereto shall terminate and

the Company and its directors, officers, employees, subsidiaries, affiliates,
stockholders, successors, assigns, agents and representatives shall have no
further obligation or liability to Executive or any other person or entity under

confidential obligation to the Company) or (iii) the Executive is required to
disclose Confidential Information by or to any court of competent jurisdiction
or any governmental or quasi-governmental agency, authority or instrumentality
of competent jurisdiction, provided, however, that the Executive shall, prior to
any such disclosure, immediately notify the Company of such requirement and
provided further, however, that the Company shall have the right, at its
expense, to object to such disclosures and to seek confidential treatment of any
Confidential Information to be so disclosed on such terms as it shall determine.

                  10.      Assignment and Transfer.

                           (a) Binding Effect. This Agreement shall be binding

                           (a) Other Obligations. Executive represents and
warrants that neither Executive's employment with the Company nor Executive's
performance of Executive's obligations hereunder will conflict with or violate
or otherwise be inconsistent with any other obligations, legal or otherwise,

                           (g) Amendment. This Agreement may be amended only by
a writing which makes express reference to this Agreement as the subject of such
amendment and which is signed by Executive and, on behalf of the Company, by its
duly authorized officer.

                           (h) Severability. If any of the provisions of this
Agreement shall otherwise contravene or be invalid under the laws of any state
or other jurisdiction where it is applicable but for such contravention or
invalidity, such contravention or invalidity shall not invalidate all of the
provisions of this Agreement, but rather the Agreement shall be reformed and
construed, insofar as the laws of that state or jurisdiction are concerned, as
not containing the provisions or provisions but only to the extent that they are
contravening or are invalid under the laws of that state or jurisdiction, and
the rights and obligations created hereby shall be reformed and construed and
enforced accordingly. In particular, if any of the covenants or provisions set
forth in paragraphs 5, 6, or 9 hereunder or any part hereof is held to be
unenforceable because of the duration of such provision or the areas covered
thereby, or otherwise, the parties hereby expressly agree that the court making
such determination shall have the power to reduce the duration and/or the areas
of such provision or otherwise limit any such provision, and, in its reduced
form, such provision shall then be enforceable.

                           (i) Construction. The headings and captions of this
Agreement are provided for convenience only and shall have no effect in
construing or interpreting this Agreement. The use herein of the word
"including," when following any general provision, sentence, clause, statement,
term or matter, shall be deemed to mean "including, without limitation". As used
herein, the words "day" or "days" shall mean a calendar day or days.

                           (j) Non-waiver. Neither any course of dealing nor any
failure or neglect of either party hereto in any instance to exercise any right,
power or privilege hereunder or under law shall constitute a waiver of any other
right, power or privilege or of the same right, power or privilege in any other
instance. All waivers by either party hereto must be contained in a written
instrument signed by the party to be charged and, in the case of the Company, by
its duly authorized officer.

                           (k) Remedies for Breach. The parties hereto agree
that Executive is obligated under this Agreement to render personal services
during the Agreement Term of a special, unique, unusual, extraordinary and
intellectual character, thereby giving this Agreement peculiar value, and, in
the event of a breach or threatened breach of any provision of this Agreement by
Executive, the injury or imminent injury to the value and the goodwill of the
Company's business could not be reasonably or adequately compensated in damages
in an action at law. Accordingly, Executive expressly acknowledges that the
Company shall be entitled to specific performance, injunctive relief or any
other equitable remedy against Executive, without the posting of a bond, in the
event of any breach or threatened breach of any provision of this Agreement by
Executive (including Sections 5, 6 and 9 hereof). Without limiting the
generality of the foregoing, if Executive breaches or threatens to breach
Sections 5, 6 or 9 hereof, such breach or threatened breach will entitle the
Company to an Order of the Court enjoining Executive from breaching any of the
provisions of Section 5, 6 or 9, as is appropriate. The rights and remedies of
the parties hereto are cumulative and shall not be exclusive, and each such
party shall be entitled to pursue all legal and equitable rights and remedies
and to secure performance of the obligations and duties of the other under this
Agreement, and the enforcement of one or more of such rights and remedies by a
party shall in no way preclude such party from pursuing, at the same time or
subsequently, any and all other


                                     - 10 -

rights and remedies available to it.

                           (l) Reasonableness of Restrictions. Executive agrees
and acknowledges that (i) the provisions of Sections 5, 6 and 9 hereof are
reasonable and necessary for the protection of the Company and do not impose a
greater restraint than is necessary to protect the goodwill or other business
interests of the Company; (ii) such provisions contain reasonable limitations as
to the time and the scope of activity to be restrained; and (iii) the
consideration provided under this Agreement including the grant of stock options
pursuant to 3(d) above, is sufficient to compensate Executive for the
restrictions imposed in Sections 5, 6 and 9 hereof. In consideration of the
foregoing and in light of Executive's education, skills and abilities, Executive
agrees that all defenses by Executive to the strict enforcement of such
provisions are hereby waived by Executive.
