             of the subsequent quarter the Distributor's payment performance is
             current, the standard discount will be reactivated for the next
             succeeding quarter. If Distributor's account is not brought current
             by the end of the subsequent quarter, the Distributor may be
             terminated immediately.

             time, the reports will contain the following information for each
             of Distributor's customers: ship-to address; part number; and
             quantity for each customer.

         K.  Report inventory values monthly, submitted to Entegris by the 20th
             day of the subsequent month, and reported on a Distributor cost
             basis.

         L.  Work with Entegris to develop and update on a quarterly schedule an
             eight (8) quarter rolling forecast. Forecasts are to be based on
             Distributor cost.

6.       DISTRIBUTOR CORRECTIVE ACTION PROGRAM

         If following the semi-annual evaluation Distributor's performance does
         not meet an acceptable performance level in relation to the semi-annual
         performance reports based on mutually agreed upon criteria contemplated
         by Section 4.G above, the Distributor will be notified. In the quarter
         following this notification, an evaluation of the Distributor's
         performance will be performed and if it still does not meet the
         performance standard, the Distributor will participate in a corrective
         action plan.

         In the first phase of corrective action the Distributor meets with
         Entegris sales territory manager to evaluate areas of unsatisfactory
         performance and to create a plan to meet or exceed the performance
         shortfalls. The plans must be developed and implemented within three
         months of initial notification.

         In the second phase the Distributor performance is monitored against
         the corrective action plan for six (6) months. If performance improves
         and meets the agreed upon performance levels in all material respects
         by the end of six (6) months, the Distributor returns to normal status.
         If at the end of six (6) months a Distributor does not meet in a
         material respect the agreed upon performance levels, Entegris has the
         right to extend the corrective action program or terminate the
         relationship with the Distributor.

         Following satisfactory completion of a corrective action program and
         meeting the agreed upon performance standard, continued performance
         above the performance standard for two (2) years without further
         corrective action is expected and failure to meet the agreed upon
         performance standard during any six month period within that two-year
         period shall result in immediate termination of the Distributor.

         The Distributor corrective action program will be enforced on a
         regional level. Distributor branch or country locations may be put on
         corrective action and terminated for non-performance without effecting
         the remaining Distributor locations covered by this agreement.

             twelve (12) months prior to the termination. The commission payable
             under this clause 13.D shall be based exclusively on the price
             Entegris charges its next distributor or on standard Entegris
             distributor cost for such products (after subtracting any
             discounts, credits or awards) and shall NOT include any other
             customary charges, including without limitation taxes,
             transportation, storage and returns. This commission shall be
             payable on a quarterly basis within thirty (30) days after the date
             of any quarter during such two-year period. The parties agree that
             the remedy provided in this Section 13.D is not a penalty.

         E.  Upon receipt of written notice of termination covered by the
             provisions in this section 13, Distributor will have 60 days to
             cure the breach to the satisfaction of Entegris before the
             termination becomes effective.

         F.  If Entegris makes material changes in this agreement pursuant to
             Section 7.C paragraph(b) hereof without the written consent of
             Distributor or Entegris materially breaches this agreement,
             Distributor shall have the right to terminate this agreement
             immediately upon written notice, and Distributor will not be bound
             by the two (2) year non-competition agreement set forth elsewhere
             in this agreement.

14.      RIGHTS UPON TERMINATION

         A.  On termination of this Agreement, for any cause whatsoever, it is
             hereby expressly agreed that Entegris shall deliver against all
             Distributor orders previously accepted subject to payment on
             delivery and will negotiate all outstanding credit memos with
             Distributor.

         B.  If Entegris should terminate this Agreement or Distributor should
             terminate this agreement as a result of material breach of this
             agreement by Entegris or the making by Entegris of material changes
             to this agreement pursuant to Section 7.C paragraph (b) hereof
             without the written consent of Distributor, all stock may be
             returned for full credit provided it is in resalable condition,
             unused, in the original packaging and of current revision level. If
             the distributor terminates the Agreement other than as a result of
             material breach of this agreement by Entegris or the making by
             Entegris of material changes to this agreement pursuant to Section
             7.C paragraph (b) hereof without the written consent of
             Distributor, Entegris is not responsible for taking back stock.

15.      CONFIDENTIALITY

         A.  Any information provided between Entegris and Distributor which the
             provider deems confidential or proprietary shall be labeled as such
             at the time of disclosure if the disclosure is written, or if
             verbal, shall be confirmed in writing as confidential within thirty
             (30) days after disclosure. The receiving party shall treat such
             information in confidence and shall take reasonable and customary
             steps to assure that such information is not shared with any third
             party. Information shall not be confidential if it is already known
             to recipient at the time of disclosure or recipient otherwise
             learns of it via a third party that is free to disclose it without
             obligation. These obligations shall remain in effect during the
             term of this Agreement and for a period of two (2) years
             thereafter.

         B.  If the parties have signed any other non-disclosure or
             confidentiality agreements, the terms of such agreements shall
             supplement the terms of this agreement.

         C.  All reports and documentation supplied to Entegris by the
             Distributor pursuant to the requirements of Section 5.J-L shall be
             considered confidential and shall be subject to the confidentiality
             obligations identified in the paragraph above.

16.      MODIFICATION

         A.  Except as provided in Section 7.C of this Agreement, this Agreement
             may only be modified in writing, signed by the Distributor and
             Entegris.

17.      MERGER

         A.  This Agreement incorporates the full understanding of the parties
             and replaces in its entirety any and all prior understandings
             relating to distribution rights and any other contracts or
             obligations between the parties. There are no other agreements
             between the parties except as stated herein, all such prior or
             other agreements being merged into this Agreement.

         B.  If Entegris waives any breach by this Distributor (or any other
             distributor), such waiver shall not constitute a waiver of any
             subsequent breach by this Distributor (or any other distributor).
