The Supply Commitment for a particular month may be modified as specifically set forth in this Agreement, but under no circumstances shall the aggregate Supply Commitment of [] New Facility Wafers be reduced.

6.2 Purchase Agreements

The Supply Commitment will apply to Products covered by the Purchase Agreements. The parties anticipate that such Purchase Agreements will apply to Products distributed by Lattice which require fabrication using the [*] Process.

6.3 Excess Capacity

Epson will use its best efforts to provide Lattice, through SMOS, with excess capacity of the New Facility if Lattice requires so in the manner specified below. In this case, APP shall be applied to Lattice’s orders of New Facility Wafers in excess of the Supply Commitment of the month. Also, the Free Wafers prescribed in Article 8 shall be provided for such excess volume of the New Facility Wafers.

First, in the event that Lattice desires to purchase New Facility Wafers in excess of the Purchase Commitment, Lattice will specify in writing the amount of capacity required, the Product(s) it desires to purchase and the date from which such capacity is required, and notify Epson of it through SMOS.

Second, Epson will then determine how much capacity is available and notify Lattice of its determination through SMOS. Epson will give Lattice priority over third parties for excess capacity of the New Facility except to the extent that Epson is already obligated to provide such third parties with capacity.

Third, the parties will then mutually agree upon a preliminary excess capacity allocation. Any excess capacity allocated under this Article 6.3 will be applied to the Supply Commitment and to the Purchase Commitment.

In order to provide Lattice with first priority for unused capacity using the specific process for Lattice, Epson agrees to give Lattice monthly written notice of any unused capacity using the specific process for Lattice for the next [*], and to provide Lattice with the first right to reserve such unused capacity for any New Facility Wafers which Lattice desires to purchase in excess of the Purchase Commitment. Lattice will have a reasonable time to elect to reserve such excess capacity. The parties acknowledge that “specific process for Lattice” above refers to Lattice’s [*] process, and that Epson’s capacity plan at the time of executing this Agreement shows that approximately [*] of total production capacity of the New

Facility will be for [*] process, subject to change by then-current production plan of Epson. Epson will notify Lattice if the capacity set aside for [*] process will change by [*] of the total capacity.

6.4 Failure to Meet Supply Commitment

6.4.1 Failure Due to Epson

In the event that (a) Epson fails to fulfill the Supply Commitment by the end of any month during the term of this Agreement or (b) Epson has reason to believe that it will be unable to fabricate the Supply Commitment by the end of such month, then Epson will take the following measures:

First, Epson will promptly notify Lattice in writing and describe the nature of the difficulty.

Second, Epson will use its best efforts to remedy the difficulty in an expeditious manner by the end of the second full month following the month in which Epson is unable to meet the Supply Commitment (in other words, the third month including the month in which the difficulty occurs).

Third, Epson will use its best efforts to make available during the above referenced three (3) month period sufficient capacity at the Sakata Facility, the Fujimi Facility or Epson’s other qualified facility to cover the deficiency between the Supply Commitment and the actual capacity subject to completion of product qualification. The parties acknowledge, however, that Epson cannot guarantee the use of such alternative capacity.

Fourth, if Epson’s inability to fulfill the Supply Commitment is due to force majeure prescribed in Article 15.14, Epson will use its best efforts to make available alternative capacity at the Sakata Facility and/or Fujimi Facility. The parties acknowledge, however, that Epson cannot guarantee the use of existing capacity at the Sakata Facility or Fujimi Facility.

Notwithstanding any provision of this Agreement to the contrary, in the event that Epson fails to fulfill the Supply Commitment (including any failure by virtue of the action or inaction of SMOS or any of the deficiency within the three (3) month period referenced above), such failure shall constitute a material breach of this Agreement and Epson, SMOS and Lattice shall discuss the relief of such breach prior to Lattice’s termination of this Agreement based on the right permitted in Article 14.4 (which termination may be made without the notice and cure period contemplated by Article 14.4).

14.3 Termination due to Acquisition or Sale of Assets.

In the event that a direct competitor or one party acquires, through merger, consolidation, acquisition or otherwise, an interest in excess of fifty percent (50%) of the voting securities or assets of the other party, or such other party transfers all or substantially all of its business to which this Agreement relates to a direct competitor of such party, the non-acquiring or non-transferring party will be permitted, upon written notice to the other party, to require that the transactions contemplated by this Agreement and the Purchase Agreements be phased out and terminated at a rate not to exceed, [*] of the business existing at the time of the acquisition or transfer according to the following schedule:

A	B

[*]	*[]**

B — Level to which business may be phased out measured as a percentage of business existing at the time of the acquisition or transfer of assets

Alternatively, the business may be phased out and terminated under this Article 14.3 in a manner otherwise agreed upon in writing by the parties.

14.4 Termination for Cause.

If either party fails to perform or violates any material obligation of this Agreement, then, sixty (60) days after providing written notice to the breaching party specifying the default (the “Default Notice”), the non-breaching party may terminate this Agreement, without liability, unless:

a) the breach specified in the Default Notice has been cured within the sixty (60) day period; or

b) the default reasonably required more than sixty (60) days to correct, and the defaulting party has begun substantial corrective action to remedy the default within such sixty (60) day period and diligently pursues such action, in which event, the non-breaching party may not terminate or suspend this Agreement unless one hundred twenty (120) days has expired from the date of the Default Notice without such corrective action being completed and the default remedied.

14.5 Termination by Epson.

In the event that Epson terminates this Agreement pursuant to this Article 14, then, unless otherwise agreed upon in writing, Epson may offset and reduce the APP to cover all direct material and labor costs for work in process rendered

* Omitted and filed separately with the SEC pursuant to a confidential treatment request

unusable by termination and will ship such work in process to Lattice, at Lattice’s expense, if requested to do so. Upon such termination, Epson shall refund the remaining portion of APP (reduced by the amount of any such offset and reduction to cover direct material and labor costs for work in process rendered unusable by the termination) no later than thirty (30) business days after the date of termination.

14.6 Termination by Lattice.

In the event that Lattice terminates this Agreement pursuant to this Article 14, then, unless otherwise agreed in writing, Lattice may either (a) request that Epson refund the remaining portion of APP (from which Epson may offset and reduce to cover all direct material and labor costs for work in process rendered unusable by the termination) and then Epson will refund the remaining portion of APP (as so offset and reduced) or (b) request Epson to complete all work in process and ship them under normal terms and conditions, and then Epson will refund the remaining portion of APP (excluding, without limitation, the costs and expenses which have arisen in connection with completing all work in process and shipping thereof), with in either such case such refund to be paid upon the earlier of:

(a) receipt of sufficient funding from a financial institution or other source for purposes of paying the refund, or

(b) thirty (30) days from the date of termination.

14.7 Retention of Rights after Termination.

Notwithstanding anything contained in this Article 14 to the contrary, in the event that either party is entitled to terminate this Agreement pursuant to Articles 14.2 (f), (g) or (h) or either party is subject to a bankruptcy, reorganization or liquidation proceeding, the other party may elect to (a) retain its rights in this Agreement existing immediately prior to termination pursuant to Article 14.2 (f), (g) or (h) or the initiation of such proceeding or (b) treat any such proceeding or attempted rejection of this Agreement by a bankruptcy trustee as an event of termination. Unless otherwise provided, in the event of such termination, Epson shall refund the remaining portion of the APP in accordance with Article 14.5 or 14.6 as applicable.

14.8 Reconciliation.

In the event of termination that results in a refund of the APP balance pursuant to Article 14 (or would result in such a refund if the APP balance were increased by the net return material account balances, if any, under the Purchase Agreement), Epson shall cause SMOS to bring current the APP, Free Wafers and return material account balances as provided for in the Purchase Agreement in order to reconcile the account with Lattice, and to refund the mutually agreed net amount.

15.1 Order of Precedence.

In the event of any conflicts between this Agreement and any Purchase Agreement, any purchase orders, acceptances, correspondence, memoranda, listing sheets or other documents forming part of an order for the Products placed by Lattice and accepted by SMOS (or Epson), priority will be given first to this Agreement, second to the Purchase Agreements, third to SMOS’s or Epson’s acceptance, fourth to Lattice’s order and then to any other documents.

15.2 Governing Law.

This Agreement shall be governed by and construed in accordance with the laws of California, U.S.A. without reference to conflict of law principles.

15.3 Dispute Resolution.

15.3.1 Meeting of Executives.

Any party may commence such proceedings by delivering a written request to the other party for a meeting of such responsible executives. The other party will be required to set a date for the meeting to be held within thirty (30) days after receipt of such request and the parties agree to exercise their best efforts to settle the matter amicably.

15.3.3 Demand for Arbitration.

Any dispute relating to and/or arising out of this Agreement will be decided exclusively by binding arbitration under procedures which ensure efficient and speedy resolution. Such an arbitration may be commenced by either party involved in the dispute (i) after the expiration of a sixty (60) day period following the written request to resolve the dispute, and/or (ii) at such earlier time as any party involved repudiates and/or refuses to continue with its

* Omitted and filed separately with the SEC pursuant to a confidential treatment request

obligations to negotiate in good faith. The arbitration hearing will be conducted in the State of Hawaii, and will be in the English language (with translators 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 Article 15.3.3 and without any abridgement of the powers of the arbitrators. The arbitration will be conducted under the Rules of the Asia Pacific Arbitration Center. Notwithstanding anything to the 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.

15.3.4 Arbitrators.

The arbitration will be conducted by three (3) arbitrators. No person with a beneficial interest in the dispute under arbitration may be an arbitrator. The parties will make reasonable efforts to select arbitrators with experience in the field of computers and law.

15.3.5 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.

15.3.6 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; provided, however, if the arbitrators appointed in Article 15.3.4 find that the position of the non-prevailing party or parties in such arbitration was without substantial justification or was frivolous, the arbitrators may assess all of the costs and expenses together with reasonable attorney’s fees against the non-prevailing party or parties.

15.4 Consequential Damages.

* Omitted and filed separately with the SEC pursuant to a confidential treatment request

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; PROVIDED, HOWEVER, THIS LIMITATION WILL NOT APPLY IF THE DAMAGES OCCUR AS A RESULT OF GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF EITHER PARTY IN THE PERFORMANCE OF THEIR RESPONSIBILITIES UNDER THIS AGREEMENT.

15.5 Assignment.

Neither party will assign, transfer or otherwise dispose of this Agreement in whole or in part without the prior consent of the other party in writing, and such consent will not be unreasonably withheld. Except in the case set forth in Article 14.3, above, this Agreement may be assigned to any Subsidiary or to a successor who has acquired a majority of the business or assets of the assigning party.

15.6 Public Announcements.

Neither party will publicly announce the execution or existence of this Agreement or disclose the terms and conditions of this Agreement without first submitting the text of such announcement to the other party and receiving the approval of the other party of such text, which approval, unless public disclosure is required by a court or a government agency, may be withheld for any reason. However, Lattice may disclose the existence and the terms of this Agreement in any document legitimately required to be filed with the Securities and Exchange Commission (and may file a copy of this Agreement required legitimately with such filing) or in accordance with generally accepted accounting procedures under the rules of the Securities and Exchange Commission or the National Association of Securities Dealers Automated Quotations stock market.
