Dear Stockholder:
 
  I am pleased to report that on October 9, 1997, your Company entered into an
agreement and plan of merger (the "Merger Agreement") with Borden Chemical,
Inc. and its wholly-owned subsidiary, MC Merger Corp. ("Offeror"), pursuant to
which Offeror has agreed to acquire the Company.
 
  In accordance with the Merger Agreement, Offeror has today commenced a
tender offer (the "Offer") to purchase all outstanding shares of the Common
Stock of the Company for $20.50 cash per share. If the Offer is successfully
completed, Offeror will, by means of a merger of Offeror into the Company (the
"Merger"), acquire for the same cash price all shares of Common Stock held by
stockholders who do not tender their shares in the Offer and do not exercise
their right to dissent from the Merger under Delaware law. The Offer is
conditioned on at least 51% of the outstanding shares of Common Stock being
validly tendered, the expiration or termination of the waiting period under
the Hart-Scott-Rodino Antitrust Improvements Act of 1976, and certain other
conditions.
 
  The Board of Directors of the Company has approved, by unanimous vote of the
directors present, the Offer, the Merger and the Merger Agreement, and has
determined that the Offer and the Merger are fair to and in the best interests
of the Company and its stockholders. The Board recommends that all
stockholders accept the Offer and tender their shares pursuant thereto.
 
  Enclosed for your consideration are copies of Offeror's tender offer
materials and the Company's Schedule 14D-9, all of which are being filed today
with the Securities and Exchange Commission. These documents, which include a
fairness opinion from the Company's financial adviser, should be read
carefully. In particular, I call your attention to Item 4 of the Schedule 14D-
9, which describes the reasons for the Board's recommendation.
 
                                          Sincerely,
 
                                          /s/ FREDERIC R. HUBER
