     ARTICLE VI:

     (a) Before there can be a valid sale or transfer of any of the shares of
this corporation by the holders thereof, the holder of the shares to be sold or
transferred shall first give notice, in writing, to the secretary of this
corporation of his intention to sell or transfer such shares. Said notice shall
specify the number of shares to be sold or transferred, the price per share, and
the terms upon which such holder intends to make such sale or transfer. The
secretary shall, within five days thereafter, mail or deliver a copy of said
notice to each of the other shareholders of record of this corporation. Such
notice may be delivered to such shareholders personally, or may be mailed to the
last known address of such shareholders, as the same may appear on the books of
this corporation. Within ten days after mailing or delivering of said notice to
said shareholders, any such shareholder or shareholders desiring to acquire any
part or all of the shares referred to in said notice shall deliver by mail or
otherwise to the secretary of this corporation a written offer or offers,
expressed to be acceptable immediately, to purchase the specified number or
numbers of such shares at the price and upon the terms stated in said notice,
accompanied by the purchase price therefor with authorization to pay such
purchase price against delivery of said shares.

     If the total number of shares specified in such offers exceeds the number
of shares referred to in said 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 of this


                                        2



corporation, which he holds, bears to the total number of shares held by all
such shareholders desiring to purchase the shares referred to in said notice to
the secretary.

     If all of the shares referred to in said notice to the secretary are not
disposed 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.

     If one or more of the other shareholders offers to purchase in the
aggregate, within said ten-day period, less than all of the shares referred to
in said notice to the secretary, the shareholder desiring to sell or transfer
shall not be obligated to accept any such offer or offers from one or more of
the other shareholders and may dispose of all of the shares of stock referred to
in said notice, to any person or persons whomsoever; 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.

     Any sale or transfer, or purported sale or transfer, of the shares of said
corporation shall be null and void unless the terms, conditions and provisions
of this Article VI are strictly observed and followed.

     (b) Each shareholder or subscriber to shares of this corporation shall be
entitled to full preemptive or preferential rights, as such rights have been
heretofore defined at common law, to purchase and/or subscribe for his
proportionate part of any shares which may be issued at any time by this
corporation.

     IN WITNESS WHEREOF, the undersigned, constituting the incorporators and
first directors of this corporation, have executed these Articles of
Incorporation on this 6th day of July, 1973.
