               ------------------ 

          (a) Upon either:  (i) the termination of the Executive's employment
with the Company for Good Reason (as hereinafter defined), or by the Company for
any reason other than the death or Disability (as hereinafter defined) of the
Executive or For Cause (as hereinafter defined) or (ii) the termination of
Executive's employment with the Company within eight months following a Change

the date of termination, with such amount to be increased by an additional month
of salary for every full month he is employed by the Company in his present

in Section 2 hereof, the Company's obligation to pay the Compensation or provide
any severance benefits (except as otherwise provided by law) will terminate as

              ------------------

determination ("For Cause Notice"), and the failure of the Executive to cure

(E) during any period of two consecutive years, individuals who at the beginning
of such period constitute the entire Board of Directors of the Company shall
cease for any reason to constitute a majority thereof unless the election, or
the nomination for election by the Company's stockholders, of each new director
was approved by a vote of at least two-thirds of the directors still in office
who were directors at the beginning of the period.

               3.11 Arbitration.

          (a) Any dispute under Section 1 of this Agreement, including but not
limited to the termination by the President of a termination For Cause or in
respect of the breach thereof will be settled by arbitration in the Borough of
Manhattan, City of New York. The arbitration will be accomplished in the
following manner.  Either party may serve upon the other party written demand
that the dispute, specifying the nature thereof, shall be submitted to
arbitration.  Within ten (10) days after the service of such demand, each of the
parties will designate an arbitrator and serve written notice of such
appointment upon the other party. If either party fails within the specified
time to appoint such arbitrator, the other party will be entitled to appoint
both arbitrators.  The two arbitrators so appointed will appoint a third
arbitrator.  If the two arbitrators appointed fail to agree upon a third
arbitrator within ten (10) days after their appointment, then an application may
be made by either party hereto, upon notice to the other party, to the American
Arbitration Association (the "AAA"), or any successor thereto, or if the AAA or
its successor fail to appoint a third arbitrator within ten (10) days after such
request, then either party may apply, with notice to the other, to the Supreme
Court of the State of New York, New York County (the "Court"), for the
appointment of a third arbitrator, and any such appointment so made will be
binding upon both parties hereto.

          (b) The decision of the arbitrators will be final and binding upon the
parties. The party against whom the award is rendered (the "non-prevailing
party") will pay 

                                       5

 
all fees and expenses incurred by the prevailing party in connection with the
arbitration (including fees and disbursements of the prevailing party's
counsel), as well as the expenses of the arbitration proceeding. The arbitrators
will determine in their decision and award which of the parties is the
prevailing party, which is the non-prevailing party, the amount of the fees and
expenses of the prevailing party and the amount of the arbitration expenses. The
arbitration will be conducted, to the extent consistent with this Section 3.11,
in accordance with the then prevailing rules of commercial arbitration of the
AAA or its successor. The arbitrators will have the right to retain and consult
experts and competent authorities skilled in the matters under arbitration, but
all consultations will be made in the presence of both parties, who will have
full right to cross-examine the experts and authorities. The arbitrators will
render their award, upon the concurrence of at least two (2) of their number,
not later than thirty (30) days after the appointment of the third arbitrator.
The decision and award shall be in writing, and counterpart copies shall be
delivered to each of the parties. In rendering an award, the arbitrators will
have no power to modify any of the provisions of this Agreement, and the
jurisdiction of the arbitrators is expressly limited accordingly. Judgment may
be entered on the award of the arbitrators and may be enforced in any court
having jurisdiction.

          IN WITNESS WHEREOF, this Agreement has been executed and delivered by
the parties hereto as of the date first above written.
