  Commitment until *** wafers have been purchased. Xilinx will
  not be required to fulfill the Purchase Commitment in the
  event that Epson fails to fulfill the Supply Commitment in the
  manner specified in Article 6.4.1. Instead, Xilinx will be
  required to purchase those New Facility Wafers that Epson is
  able to fabricate. Xilinx will not be required to fulfill the
  Purchase Commitment in the event of difficulties caused by
  both Epson and Xilinx. Instead, the parties will mutually
  agree in writing upon a fair and equitable solution.

7.2 Sale of Unused Capacity
  In the event that Xilinx is unable to fulfill the Purchase
  Commitment in any month for reasons not due to Epson, Epson
  will use its best efforts to sell unused capacity to other
  customers, or to allocate unused capacity for the fabrication
  of Epson products during such month. Further, Epson's Supply
  Commitment for such month will be reduced to the same extent
  that Xilinx is unable to fulfill the Purchase Commitment. When
  Xilinx desires to increase its monthly purchases after Epson
  has sold or otherwise allocated unused capacity, then Epson
  will use its best efforts to increase capacity for Xilinx to
  the Supply Commitment in an expeditious manner. The parties
  will mutually agree upon the specific rate at which Epson will
  be required to ramp up capacity to the Supply Commitment.

  provisions of Existing Agreements, it being understood that
  such provisions will apply.
14.2 Marking
  If Confidential Information is provided in a tangible form, it
  will be marked as confidential or proprietary. If Confidential

  to those employees (including any contract employees or
  consultants) of such party on a need-to-know basis, and not
  disclose it to other employees or parties, and (c) restrict

  required to carry out its obligations under this Agreement.

14.4 Exceptions to Confidentiality Obligations
  Neither party will use or disclose the other party's
  Confidential Information except as permitted by this
  Agreement. The receiving party, however, will have no
  obligations concerning the disclosing party's Confidentiality
  Information if the disclosing party's Confidential
  Information:

     a) is made public before the disclosing party discloses it
     to the receiving party;
     b) is made public after the disclosing party discloses it to
     the receiving party (unless its    publication is a breach

     before the disclosing party discloses it to  the receiving
     party

     independent development is supported by documentary
     evidence; or
     e) is rightfully obtained by the receiving party from a
     third party who is lawfully in possession    of the
     information and not in violation of any contractual, legal
     or fiduciary obligation to the     disclosing party with
     respect to the information.

  the dispute (i) after the expiration of a sixty (60) day

  negotiate in good faith. The arbitration hearing will be
  conducted in the State of Hawaii, and will be in the English
  language (with translations and interpretations as reasonable
  for the presentation of evidence and/or conduct of the
  arbitration). Notwithstanding anything to the contrary, any
  party may apply to any court of competent jurisdiction for
  interim injunctive relief as may be allowed under applicable
  law with respect to irreparable harm which cannot be avoided
  and/or compensated by such arbitration proceedings, without
  breach of this Section 16.3.3 and without any abridgement of

  contrary, (i) the arbitrators will have the power to order
  discovery to the extent they find such discovery necessary to
  achieve a fair and equitable result and (ii) the arbitrators
  shall require pre-hearing exchange of documentary evidence to
  be relied upon by each of the respective parties in their
  respective cases in chief, and pre-hearing exchange of briefs,
  witness lists,and summaries of expected testimony.

  The arbitrators will make their decision in writing.

16.2.4 Arbitrators

  arbitration may be an arbitrator. The parties will make
  reasonable efforts to select arbitrators with experience in

16.2.5 Binding Effect
  The decision or award rendered or made in connection with such
  arbitration will be binding upon the parties and judgment
  thereon may be entered in any court having jurisdiction and/or
  application may be made to such court for enforcement of such
  decision or award. However, the arbitrators will not have the
  authority to create any licenses. They will only be permitted
  to enforce licenses which the parties have otherwise agreed to
  in the Agreement or the Existing Agreements.

16.2.6 Expenses
  The expenses of the arbitrators will be shared equally by the
  parties; each party will otherwise be responsible for the
  costs and attorney's fees incurred by it.

16.3 Consequential Damages
     IN NO EVENT WILL EITHER PARTY BE LIABLE TO THE OTHER PARTY
  FOR ANY   INDIRECT, SPECIAL, CONSEQUENTIAL OR INCIDENTAL DAMAGES
  (INCLUDING LOST     PROFITS) WHETHER BASED ON WARRANTY, CONTRACT,
  TORT OR ANY OTHER LEGAL  THEORY REGARDLESS OF WHETHER SUCH PARTY
  HAD ACTUAL OR CONSTRUCTIVE    NOTICE OF SUCH DAMAGES.
