                           SALE OR TRANSFER OF SHARES:

     (a) Before there can be a valid sale or transfer of any of the shares of
the corporation by any holder thereof, he shall first offer said shares to the
corporation and then to the other holders of common shares in the following
manner:

     (1) Such offering shareholder shall deliver a notice in writing by mail or
otherwise to the secretary of the corporation stating the price, terms and
conditions of such proposed sale or transfer, the number of shares to be sold or
transferred, and his intention so to sell or transfer such shares. Within five
(5) days thereafter, the corporation shall have the prior right to purchase all
of said shares at the expiration of said five (5) day period, or prior thereto,


                                       4



upon the determination of the corporation to purchase none or only a portion of
such shares so offered, the secretary of the corporation shall, within five (5)
days thereafter, mail or deliver to each of the other shareholders a notice
setting forth the particulars concerning said shares not so purchased by the
corporation described in the notice received from the offering shareholder. The
other shareholders shall have the right to purchase all of the shares specified
in said secretary's notice by delivery to the secretary by mail or otherwise a
written offer or offers to purchase all or any specified number of such shares
upon the terms so described in the secretary's notice if such offer or offers
are so delivered to the secretary within ten (10) days after mailing or
delivering such secretary's notice to other shareholders. If the total number of
shares specified in such offers so received within such period by the secretary
exceeds the number of shares referred to in such secretary's notice, each
offering shareholder shall be entitled to purchase such proportion of the shares
referred to in said notice to the secretary as the number of shares held by all
such shareholders desiring to purchase the shares referred to in said notice to
the secretary.

     (2) If all of the shares referred to in said notice to the secretary are
not disposed of under such apportionment, each shareholder desiring to purchase
shares in a number in excess of his proportionate share, as provided above,
shall be entitled to purchase such proportion of those shares which remain thus
undisposed of, as the total number of shares which he holds bears to the total
number of shares held by all of the shareholders desiring to purchase shares in
excess of those to which they are entitled under such apportionment.

     (3) If none or only a part of the shares referred to in said notice to the
secretary is purchased, as aforesaid, by the corporation or in accordance with
offers made by other shareholders within said ten (10) day period, the
shareholder desiring to sell or transfer may dispose of all shares of stock
referred to in said notice to the secretary not so purchased by


                                       5



the corporation or by the other shareholders, to any person or persons he may so
desire; provided, however, that he shall not sell or transfer such shares at a
lower price or on terms more favorable to the purchaser or transferee than those
specified in said notice to the secretary.

     (4) Within the limitations herein provided, this corporation may purchase
the shares of this corporation from any offering shareholder, provided, however,
that at no time shall this corporation be permitted to purchase all of its
outstanding voting shares. Any sale or transfer or purported sale or transfer of
the shares of the corporation shall be null and void unless the terms,
conditions and provisions of this Article are strictly observed and followed.

     (b) Each shareholder of this' corporation shall be entitled to full
pre-emptive or preferential rights, as such rights are defined by law, to
subscribe for or purchase his proportional part of any shares which may be
issued at any time by this corporation.

     IN WITNESS WHEREOF, the undersigned and above named incorporators of this
corporation have executed these Articles of Incorporation on this 18th day of
June, 1962.
