Executive has been unable to discharge his essential job duties by reason of
illness or injury for either (A) a period of ninety (90) consecutive days or (B)
one hundred eighty (180) days in any twelve-month period.  In the event of any
dispute regarding the existence of Executive's Disability hereunder, the matter

               (f) If the Executive's employment is terminated pursuant to this
Section 4 or for any other reason, the Executive shall not be entitled to any

base salary described in Section 3(a) above until the earlier of (A) twelve (12)
months following such termination or (B) the termination date set forth in
Section 1(a)(i) of this Agreement.

                   (iv)  if the Executive's employment is terminated other than

required pursuant to Section 12(a) of this Agreement.

               (ii)  Notwithstanding the foregoing, a termination shall not
be treated as a termination for Good Reason (A) if Executive shall have
specifically consented in writing to the occurrence of the event giving rise to
the claim of termination for Good Reason or (B) unless Executive, within 30 days
after receiving written notice from the Company specifying in reasonable detail
the occurrence of one of such events, shall have delivered a written notice to
the Company stating that he intends to terminate his employment for Good Reason
and specifying the factual basis for such termination and such event, if capable
of being cured, shall not have been cured within 30 days of the receipt by the
Company of such notice.

Reason pursuant to this subsection (g), the Company shall pay Executive (or, in
the event of his death, his devisee, legatee or, if there is none, his estate) a
lump-sum amount equal to the lesser of (A) the Executive's monthly base salary
in effect on the date of termination, or (B) the Executive's monthly base salary
in effect on the date of termination, multiplied by the number of months
remaining until the termination date set forth in Section 1(a)(i) of this
Agreement.  Executive will also be entitled to any vested benefits under any
employee benefit plans.

               (a) The Executive represents that he has full authority to enter

under any contractual restraint which would prohibit the Executive from
satisfactorily performing his duties to the Company under this Agreement.

               (b) The Executive hereby agrees to indemnify and hold harmless
the Company, its officers, directors and stockholders from and against any
losses, liabilities, damages or costs (including reasonable attorney's fees)

that has been rightfully received by the Executive from a third party without
breach or confidential limitations, or (iii) the learned skill of the Executive

will be available to the Executive in confidence. Except in the performance of
the Executive's duties on behalf of the Company, the Executive shall not,
directly or indirectly for any reason whatsoever, disclose or use any such
Confidential Material, unless such Confidential Material ceases (through no
fault of Executive's) to be confidential because it has become part of the
public domain. All records, files, drawings, documents, equipment and other
tangible items, wherever located, relating in any way to the Confidential
Material or otherwise to the Company's business, which the Executive prepares,
uses, or encounters, shall be and remain the Company's sole and exclusive
property and shall be included in the Confidential Material. Upon termination of

Competition."  The Executive agrees that the Executive shall not engage in
Unfair Competition either during the time the Executive is employed by the
Company or at any time thereafter.

                                      -5-

shareholder) shall not, directly or indirectly, for a period of one (1) year:

              (i)  solicit for employment and/or employ any employee,

Agreement) or induce or attempt to induce any customer, supplier, licensee or
other business relation of the Company or any Subsidiary to cease doing business

and/or injunctive or other relief in order to enforce or prevent any violations
of the provisions thereof (without posting a bond or other security).

          (e) Upon termination of this Agreement, the Executive shall be deemed
to have resigned from all offices and directorships then held with the Company
or any affiliate entity.

Company or termination thereof, shall be settled by arbitration (other than
injunctive relief) by one arbitrator who shall be a retired judge in accordance
with the rules of J.A.M.S./Endispute, and judgment upon such award rendered by
the arbitrator may be entered in any court having jurisdiction thereof.  The

relying for its protection upon the existence and validity of the provisions of
this Agreement, that the services to be rendered by the Executive are of a
special, unique and extraordinary character, and that irreparable injury will
result to the Company from any violation or continuing violation of the
provisions of this Agreement for which damages may not be an adequate remedy.
Accordingly, the Executive hereby agrees that in addition to the remedies
available to the Company by law or under this Agreement, the Company shall be
entitled to obtain such equitable relief (without bond) as may be permitted by
law in a court of competent jurisdiction including, without limitation,
injunctive relief from any violation or continuing violation by the Executive of
any term or provision of this Agreement.  If any action (including arbitration)
shall be brought pursuant to this Agreement, the prevailing party shall be
entitled to its costs and expenses, including reasonable attorneys' fees.

other corporation, partnership or business entity, or all or substantially all
of the Company's business or assets shall be transferred in any manner to any
other corporation, partnership or business entity, then such successor to the
Company shall thereupon succeed to, and be subject to, all rights, interests,
duties and obligations of, and shall thereafter be deemed for all purposes
hereof to be, the "Company" under this Agreement. This Agreement shall inure to
the benefit of and be enforceable by Executive's personal or legal
representatives, executors, administrators, successors, heirs, distributees,
devisees and legatees. If Executive should die, any amounts payable to him
hereunder shall be paid in accordance with the terms of this Agreement to

designee, to his estate.

               (b) This Agreement is personal in nature and the Executive shall

Agreement may be waived only by a written instrument executed by the parties to
this Agreement or, in the case of a waiver, by the party waiving compliance.
Any such written instrument must be approved by the Board to be effective as
against the Company.  The failure of any party at any time or times to require
performance of any provision of this Agreement shall in no manner affect the
right at a later time to enforce the same.  No waiver by any party of the breach
of any term or provision contained in this Agreement, whether by conduct or
otherwise, in any one or more instances, shall be deemed to be, or construed as,
a further or continuing waiver of any such breach, or a waiver of the breach of
any other term or covenant contained in this Agreement.

          14.  Notice.  All notices, requests or consents required or permitted
               ------
