ITEM 5.  OTHER EVENTS.

     PURCHASE OF THE LAWTER BLOCK.  On June 26, 1997, the Company entered into a
Purchase and Standstill Agreement and Mutual Release dated as of June 26, 1997 
(the "Purchase Agreement") pursuant to which the Company will purchase the
3,157,220 shares of the Company's Common Stock held by Lawter International,
Inc. ("Lawter"), representing approximately 27.38% of the issued and outstanding
Common Stock of the Company (the "Lawter Block"), for a purchase price of $19.00
per share.  The Company will use approximately $25 million to $30 million of
cash on hand, together with bank borrowings to fund the $59,987,180 aggregate
purchase price required by the Purchase Agreement.

     The Purchase Agreement provides that, if prior to September 30, 1998, there
is a transaction which results in a change in control of the Company in which
the stockholders of the Company receive more than $19.00 per share for their
common stock, the Company will pay Lawter an adjustment amount equal to the
product of the difference in such prices times 3,157,220. Lawter has agreed that
it will not acquire, directly or indirectly, any securities of the Company (or
assist others in such regard) for a period of ten years following the completion
of the purchase of the Lawter Block by the Company.

     The purchase of the Lawter Block is to be completed on July 8, 1997.

     After the purchase of the Lawter Block is completed by the Company,
approximately 8.2 million shares of the Company's Common Stock will remain
issued and outstanding and approximately 16.8 million shares of Common Stock
will then be available for issuance by the Company.

     The foregoing description of the Purchase Agreement is qualified in its
entirety by reference to the text of the Purchase Agreement which is attached as
an exhibit to this report and is incorporated herein by reference.

     POSTPONEMENT OF PRESENTATION OF DUAL CLASS AMENDMENT TO STOCKHOLDERS.  The
Company has determined to postpone consideration by its stockholders of a
proposed Amendment to the Company's Restated Certificate of Incorporation to
create a new class of non-voting common stock until the Company's Annual Meeting
of Stockholders to be held September 9, 1997.  Consequently, the Company has
cancelled the special meeting of stockholders which had been previously
scheduled for July 23, 1997 to consider the Amendment.
