         1.2) Designated Sale.  A Designated Sale for purposes of this Agreement
shall be any Sale or interrelated series of Sales by either or both of the
Shareholders which:

                  (a) Constitutes a private sale not involving the consummation
         of a public market transaction; and

                  (b) Immediately after the Sale, the transferee is a
         shareholder of the Corporation who is required to file Schedule 13D or
         13G with the Securities Exchange Commission.

         1.3) Grant of Right of First Refusal. Each of the Shareholders hereby
grants to the Corporation the right, as further described herein, to purchase
from the Shareholders, at the price and on the terms described herein, all but
not part of the Corporation Stock proposed to be disposed of in a Designated
Sale.

         1.4) Procedure and Limitations.A Shareholder shall not sell, assign, or
otherwise dispose of any of his shares of Corporation Stock in a Designated Sale
without first giving written notice to the Corporation (the "Sale Notice") of
the offer he has received and his intention to accept such offer. The Sale
Notice shall (i) certify that the transferee's offer to purchase is a bona fide
offer with capability to consummate; (ii) state the number of shares of
Corporation Stock proposed to be disposed of and the amount of consideration
offered; and (iii) provide the name and Social Security Account Number of the
proposed transferee. The Corporation shall have, for a period of five (5) days
after receipt of the Sale Notice (the "Option Period"), an option (the "Option")
to purchase, at the price and on the same terms set forth in the Sale Notice,
all but not part of the shares of Corporation Stock specified in the Sale
Notice. The Option shall be exercised, if at all, by delivery of written notice
of such exercise (the "Exercise Notice") within the Option Period to the
Shareholder whose Corporation Stock is the subject of such Option (the "Selling
Shareholder"). The Corporation shall pay the purchase price to the Selling
Shareholder, and the Selling Shareholder shall deliver the shares of Corporation
Stock being sold, within five (5) days of the delivery of the Exercise Notice to
the Selling Shareholder. If the Option is not exercised, the Selling Shareholder
may, at any time within thirty (30) days after expiration of the Option Period,
sell or otherwise dispose of such Corporation Stock in a Designated Sale free
and clear of all other terms and conditions of this Agreement, but only to the
transferee and at the price contained in the Sale Notice, provided that if the
purchase price to be paid for the Corporation Stock in such Designated Sale is
based on the trading price of the Corporation Stock of such Designated Sale as
quoted on the OTC Bulletin Board or such other national or regional exchange on
which the Corporation Stock is then traded and the Option is not exercised, the
Selling Shareholder may sell or otherwise dispose of such Corporation Stock and
shall not be required to deliver to the Corporation an additional Sale Notice if
the trading price of the Corporation Stock has changed during the period from
the date of delivery of the Sale Notice to the closing of such Designated Sale.
If such sale or disposition is not made within such 30-day period, any shares of
Corporation Stock not disposed of shall again be subject to this Agreement, and
the Shareholder must again comply with all provisions of this Article 1 prior to
consummating a Designated Sale.
