Associated Materials Incorporated

                                    AGREEMENT

         This Agreement, which together with the Land Sale Contract described in
paragraph 1 below, represents the entire agreement of the parties hereto with
respect to the subject matter hereof, is between Shintech Incorporated
("Seller") and Alside Division of Associated Materials Incorporated ("Buyer").
The parties hereto agree as follows:

1.       Seller  agrees to sell to Buyer, and Buyer agrees to purchase
         from Seller, approximately 20 acres of land outlined on Exhibit "A" at
         Seller's plant site in  Freeport,  Texas,  at a selling  price of $[ ]*
         per  acre.  Such sale is contingent  upon, and Buyer agrees to use
         said land for, the  construction of an extrusion facility to be
         operated by Buyer. Seller and Buyer agree to enter into a Land Sale
         Contract separate from this Agreement to consummate this part of the
         transaction,  which will contain the foregoing terms and such other
         terms as may be mutually  agreeable  to Seller and Buyer.  The
         transfer of the land to Buyer shall  be  completed  within  60 days
         from the  date of this  Agreement.  Buyer estimates that the
         construction of the extrusion  facility will be completed and  ready
         to commence production by December 31, 1998.

2.       Seller agrees to grant Buyer an appropriate right-of-way easement to
         obtain access to Highway 332 and to work with Buyer to obtain a
         right-of-way from Hoffman LaRoche, Dow Chemical, and, perhaps, others
         for a rail spur from the existing Union Pacific line. If Buyer is
         unable to obtain an acceptable right-of-way for a rail spur from such
         companies, Seller will use best reasonable efforts to locate another
         20-acre site with rail access adjacent to or nearby Seller's plant site
         for Buyer's use, in which event Buyer will construct its plant on such
         substitute site. In the event that Seller is not able to locate such
         substitute site, Buyer and Seller acknowledge this Agreement shall
         become null.

3.       Seller will sell and deliver to Buyer, and Buyer will purchase from
         Seller, for Buyer's own use and consumption at Buyer's West Salem, OH,
         Ennis, TX, and Freeport, TX plants on the terms and conditions stated
         herein, Seller's current Suspension Type PVC SE95OEG or Type SE950W
         resin ("resin").

4.       Buyer will provide Seller, thirty (30) days prior to each calendar
         quarter, its best estimate of the amount of resin to be purchased for
         each plant during the ensuing quarter.

5.       Delivery of resin to Buyer's West Salem, OH and Ennis, TX plants shall
         be by rail car unless otherwise agreed to by the parties. Delivery of
         resin to Buyer's Freeport, TX plant shall be by hopper trailer, unless
         otherwise agreed to by the parties. Title and risk of loss shall pass
         from Seller to Buyer as the rail car or hopper trailer containing the
         resin arrives at Buyer's plants.

6.       During the term of this  Agreement  and  subject to force
         majeure, Buyer agrees to buy and Seller agrees to sell approximately
         sixty percent (60%) of Buyer's entire resin requirements in each of
         1998 and 1999, and approximately seventy  percent (70%) of Buyer's
         entire resin  requirements  thereafter,  which

with the Securities and Exchange Commission.

         entire resin  requirements,  per year are estimated to be 114 million
         pounds in 1998,  129 million  pounds in 1999,  143 million pounds in
         2000, and 157 million pounds  thereafter.  Seller shall ship and Buyer
         shall take resin in  reasonably uniform monthly quantities,
         acknowledging the seasonality of Buyer's production requirements. Buyer
         and Seller agree that Seller will provide approximately all of Buyer's
         resin  requirements  at Buyer's  Freeport,  TX, and West Salem,  OH
         plants. Notwithstanding the foregoing, (i) upon Buyer giving Seller
         [ ]* calendar days prior  notice,  Seller  agrees to supply  Buyer up
         to [ ]* pounds per month in excess of the monthly quantities stipulated
         above, and (ii) to the extent that Buyer's purchases  are less than
         [ ]* of Seller's  obligation to supply based on the above estimates for
         three consecutive months, Seller shall have the right to reduce Seller
         obligation to supply to [ ]*% of the actual average  monthly usage for
         the previous [ ]* months.

7.       Pricing for the sale and purchase of the resin shall be as follows

         a.       Every month during the term of this Agreement, Seller and
                  Buyer shall discuss and determine in good faith the Base Price
                  ("BP") on a mutually acceptable basis for such month, taking
                  into account changes, if any, in the resin market conditions
                  for such month. BP does not reflect any contractual discounts,
                  allowances, or other price adjustments, but does include
                  applicable taxes. [
                                                                           ]*

         b.       [

                                                                           ]*

         c.       Except as provided in subsection (d) below, all pricing is
                  F.O.B. point of destination.

         d.       The following freight charges will be added to the MSP to
                  arrive at the monthly selling price for deliveries to Ennis,
                  TX and West Salem, OH.

                                                                         ]*

                  The freight charges may be adjusted on an annual contract
                  basis based upon changes in tariff rates.

         e.       For all rail shipments to Ennis, an additional discount of
                  [      ]* shall be allowed.

         f.       For each  calendar  year during the term of this  Agreement,
                  if Buyer  purchases  the  following volumes from Seller:

                  o        [  ]* million in 1998;
                  o        [  ]* million in 1999.
                  o        [  ]* million in 2000; and
                  o        [  ]* million thereafter,

                  an additional  discount of [       ]* will be allowed on all
                  resin  purchased by Buyer from Seller hereunder
                  ("End- of-Year Discount")

8.       Payment  terms for resin  purchases  shall be net sixty  (60)  days
         from date of  shipment  from  Seller's Freeport plant.

9.       In the event that in any month during this Agreement  Buyer
         receives a commercially  reasonable  quotation from  Occidental
         Chemical  Corporation or Borden  Plastics and Chemicals  for shipment
         that month to Ennis,  West Salem or Freeport  of  like  quantities  of
         a  product  of  equal  quality  to  the  same destination(s)  upon
         substantially the same payment and shipment terms as herein provided
         that is lower than the price determined  pursuant to paragraph 7
         hereof (net of all discounts  contemplated  hereunder) for such month,
         Buyer shall give Seller an  opportunity to review the pricing
         hereunder for such  destination(s) for the particular month.  Seller
         agrees to give every reasonable  consideration to such lower price
         offer for such month,  based upon Seller's  knowledge of the then
         current  market  conditions.  If Seller meets such lower price,  no
         further discounts  shall apply to such volume.  If Seller  elects not
         to meet such lower price, whether or not such lower price offer was
         commercially reasonable, Seller and Buyer shall be relieved from their
         respective  obligations under paragraph 6 above  for  such
         destinations  only  for the  particular  month.  However,  for
         End-of-Year  Discount calculation  purposes,  the amount purchased at
         such lower price will count toward the volume  described  in paragraph
         7 above,  whether or not Seller elects to meet such lower price.
         Buyer agrees to provide Seller with a copy of the quotation
         confirming such lower price or other  documentation  of such lower
         price acceptable to Seller.

         expertise in connection with the selection and use of the resin

         expertise in the handling, storage, transportation, treatment, use and
