          WHEREAS, the Optionee is an employee of the Company or a subsidiary
thereof;

          WHEREAS, the Company desires to provide to the Optionee an additional
incentive to promote the success of the Company;

          NOW, THEREFORE, in consideration of the foregoing, the Company hereby
grants to the Optionee the right and option to purchase shares of Common Stock
of the Company under and pursuant to the terms and conditions of the Company's
1995 Key Employees and Advisors Stock Option Plan (the "Plan") and upon the
following terms and conditions:

          1.  GRANT OF OPTION.  The Company hereby grants to the Optionee the 
right and option (the "Option")  to  purchase  up  to  three hundred fifty
thousand (350,000) shares of Common Stock of the Company (the "Option Shares")
during the following periods:

               (i)   two hundred thousand (200,000) shares commencing
immediately and terminating at 5:00 P.M., New York City time, five (5) years
from the date hereof (the "Expiration Date"); and

               (ii)  an additional one hundred fifty thousand (150,000) shares
commencing one (1) year from the date hereof and terminating at 5:00 P.M., New
York City time, on the Expiration Date.

          Notwithstanding the foregoing, in the event (a) the closing bid price
for the Company's shares of Common Stock shall equal or exceed three dollars
($3.00) per share (subject to anti-dilution adjustment for certain events such
as stock splits and reverse stock splits, as provided for in the Plan), or (b) a
"change in control" of the Company or "business combination" (as such terms are
defined below) shall occur, the Option shall become immediately exercisable in
full.

          As used in this Agreement, a "change in control" shall only be deemed
to have occurred if any "person" (as such term is defined in Section 13(d) of
the Securities Exchange Act of 1934, as amended (the "1934 Act")) hereafter
becomes the "beneficial owner" (as such term is defined in Rule 13d-3,
promulgated under the 1934 Act) of securities of the Company representing more
than fifty percent (50%) of the Company's then outstanding securities having the
right to vote on the election of directors (calculated

in accordance with the provisions of Rule 13d-3) ("Voting Securities"), except
that changes in direct or indirect ownership of Company securities resulting
from or relating to the following shall not be considered to be or result in a
"change in control":

          (i) transfers by Ray English and Associates ("RE&A") or Dorothy A.
          English (collectively, the "Beneficial Owners") to Dorothy A. English,
          as Voting Trustee under that certain Voting Trust Agreement dated July
          15, 1995 (the "Voting Trustee"), or from the Voting Trustee to either
          or both of the Beneficial Owners;

          (ii) transfers by the Voting Trustee to any successor voting trustee;
          or

          (iii) transfers by RE&A to any "affiliate" thereof (as such term is
          defined in Rule 405, promulgated under the Securities Act of 1933, as
          amended).

          As used in this Agreement, the term "business combination" shall mean
any sale by the Company of all or substantially all of its assets or any merger
or consolidation to which the Company is a party (other than one consummated for
the purpose of changing the Company's domicile or one following which the
stockholders of the Company retain or obtain at least fifty percent (50%) of the
Voting Securities of the surviving or consolidated entity or the parent
thereof).

          2.   EXERCISE PRICE.  The exercise price of each of the Option Shares
shall be sixty two and one-half cents ($.625) (the "Option Price").

          3.   EXERCISE OF OPTIONS.  The Option shall be  exercised in
accordance with the provisions of the Plan.  Subject to the provisions of the
Plan, as soon as practicable after the receipt of notice of exercise and payment
of the Option Price as provided for in the Plan, the Company shall tender to the
Optionee certificates issued in the Optionee's name evidencing the number of
Option Shares covered thereby.

          4.   TRANSFERABILITY.  The Option shall not be transferable other than
by will or the laws of descent and distribution and, during the Optionee's
lifetime, shall not be exercisable by any person other than the Optionee.

          5.   TERMINATION OF EMPLOYMENT.  In the event the Option becomes
exercisable, in whole or in part, whether through the passage of time or
acceleration, it shall remain exercisable to such extent until the Expiration
Date notwithstanding any subsequent termination of the Optionee's employment
with the
