securities convertible into, exercisable or exchangeable for or evidencing any
right to purchase or subscribe for any shares of Common Stock (either pursuant
to Rule 144 under the Securities Act of 1933, as amended, or otherwise) or
dispose of any beneficial interest therein without the prior written consent of
the President of the Company, except that the Undersigned may sell in brokerage
transactions in the aggregate (a) up to ten percent (10%) of the shares of
Common Stock owned beneficially or of record (the "Stock") during the period
from six (6) months after the date hereof (the "Closing Date") until twelve (12)
months thereafter, (b) an additional ten percent (10%) of the Stock during the

place "stop orders" on its books to prevent any transfer of securities of the
Company by the Undersigned in violation of this Agreement. Notwithstanding the
foregoing, if any Common Stock is released from escrow to the Undersigned during
the Restricted Term in connection with Section 4.2 of the Purchase Agreement,
such shares of Common Stock so released shall not be subject to the foregoing
limitations on the amount of shares of Common Stock which the Undersigned may
Transfer.
