If the parties cannot agree on a resolution in such negotiations, then this issue shall be referred to arbitration pursuant to the arbitration procedures set forth in Exhibit C hereto to decide whether such breach can be cured or any other alternative remedy should be adopted. In the event the breach is an incurable breach, the parties agree that the matter shall be referred to arbitration pursuant to the arbitration procedures set forth in Exhibit C hereto to determine the appropriate remedy. In the event that either party submits the dispute to arbitration, both parties shall cooperate in such binding arbitration in accordance with Exhibit C.

(iii) Acknowledgment. HCT does hereby agree that the license to OpNext Japan IP in this HCT IP License Agreement is the only license that HCT shall have to the OpNext Japan IP, and that any other prior or contemporaneous license, including without limitation the OpNext Japan IP License Agreement to such OpNext Japan IP shall be replaced in its entirety by this HCT IP License Agreement.

(i) Ten Years. The obligations set forth in this Section 5 shall expire on July 31, 2011; provided, however, that the license under OpNext Japan IP existing as of July 31, 2011 shall continue, under reasonable terms and conditions to be agreed between the parties, until the expiration of all of such OpNext Japan IP.

(ii) Breach. Notwithstanding (i) above, if either of the conditions set forth in Section 5(b)(i) is met, OpNext Japan may elect to be completely relieved of its obligations set forth in this Section 5. If OpNext Japan elects to be relieved of its obligations under this Section 5, the parties shall renegotiate in good faith and on commercially reasonable terms a new license governing the OpNext Japan IP.

Section 6. Representations and Warranties of HCT. HCT represents and warrants to OpNext Japan that HCT owns or has the right to use and sublicense the HCT Transferred IP.

OpNext Japan agrees that within fifteen (15) Business Days of receipt of such request and proposed nondisclosure agreement, OpNext Japan shall, at its sole discretion, either: (i) enter into the proposed nondisclosure agreement and directly provide the requested confidential information to such HCT sublicensee; (ii) propose reasonably modified terms and conditions of the nondisclosure agreement under which OpNext Japan will provide the requested confidential information to HCT’s sublicensee; or (iii) commence discussions with HCT to reach a resolution of OpNext Japan’s concerns with respect to such disclosure, if OpNext Japan believes such disclosure is not in the best interest of the parties. In the event that OpNext Japan elects to exercise option (ii) or (iii), the parties agree to negotiate in good faith and on reasonable terms to resolve the situation within a reasonable amount of time, which shall not exceed fifteen (15) Business Days of OpNext Japan’s provision of such a response. If the parties cannot agree on a resolution in such negotiations, then this issue shall be referred to arbitration pursuant to the arbitration procedures set forth in Exhibit C hereto. In the event that either party submits the dispute to arbitration, both parties shall cooperate in such binding arbitration in accordance with Exhibit C.

(c) OpNext Japan’s and HCT’s Trademark, Trade Names, etc. If necessary, OpNext Japan and HCT may negotiate in good faith the terms and conditions under which HCT and OpNext Japan may use any of the trademarks, trade names, trade dress, service marks, logos and/or domain names relating to the Business and any other means of identifying the Business or its products or services from and after the Spin-Off Date.

Section 8. Representations and Warranties of OpNext Japan. OpNext Japan represents and warrants to HCT that OpNext Japan owns or has the right to use and sublicense the OpNext Japan IP that has been filed by (to the extent there are any patent applications) or issued to, OpNext Japan, as of the Spin-Off Date.

(b) No Additional Representations.

Without limiting the generality of the foregoing, HCT makes no representation or warranty with respect to the HCT Transferred IP and Future HCT IP, express or implied, beyond those expressly made in Section 6, including any implied representation or warranty as to the condition, merchantability, suitability or fitness for a particular purpose of any of the HCT Transferred IP and Future HCT IP and, except for the express representations and warranties of HCT contained in Xxxxxxx 0, XxXxxx Xxxxx takes the HCT Transferred IP and Future HCT IP on an “as is” and “where is” basis.

Section 10. Mutual Covenants. HCT and OpNext Japan covenant and agree as follows:

(a) Press Releases. Each party agrees to consult with the other as to the general nature of any news releases or public statements with respect to the transactions contemplated by this HCT IP License Agreement, and use Commercially Reasonable Efforts not to issue any news releases or public statements inconsistent with results of such consultations.

(c) Injunctive Relief. The parties acknowledge and agree that money damages would be inadequate to remedy any breach of the confidentiality obligations in Sections 7(b) and 9(a) and that the non-breaching party shall be entitled to obtain equitable or other remedies with respect to any such breach, including injunctive relief.

Section 11. Termination and Survival.

(a) Status of HCT. Notwithstanding anything else in this Agreement (including, without limitation, the termination provisions set forth in Section 11(b) below), if at any time HCT ceases to be a Subsidiary of Hitachi, all the obligations set forth in this Agreement and the Jointly Developed IP License Agreement shall terminate at such time but only with respect to Assigned IP, Future HCT IP, OpNext Japan IP and Jointly Developed IP; provided, however, that: (i) the obligations set forth in Sections 7(b), 9(a), 10, 11, 12, 17, 20, 27, and 28 of this HCT IP License Agreement as they relate to Assigned IP, Future HCT IP and OpNext Japan IP, and Sections 6, 13-17, 20-22 of the Jointly Developed IP License Agreement as they relate to Jointly Developed IP shall survive such termination; and (ii) all of the obligations of this HCT IP License Agreement with respect to HCT Transferred IP, except for Sections 2, 4, 5, 7(a) (as Section 7(a) relates to Future HCT IP), 9(c) and 13 of this HCT IP License Agreement, shall survive such termination; and further provided, that the parties shall discuss in good faith entering into new agreements regarding the same subject matter on commercially reasonable terms.

(b) Termination for Breach or Expiration. To the extent the terms of this HCT IP License Agreement provide for rights, interest, duties, claims, undertakings and obligations subsequent to the termination (other than a termination pursuant to Section 11(a)) or expiration of this HCT IP License Agreement, such terms of this HCT IP License Agreement shall survive such termination or expiration, including but not limited to the terms of Sections 1, 2 (to the

Section 12. Dispute Resolution. In the event of any dispute under this HCT IP License Agreement, as a condition precedent to either party seeking arbitration (except for actions seeking injunctive relief), the parties will attempt to resolve such dispute by good faith negotiations. Such negotiations shall first involve the individuals designated by the parties as having general responsibility for the HCT IP License Agreement. If such negotiations do not result within thirty (30) days from written notice of either party indicating that a dispute exists (a “Dispute Notice”) in a resolution of the dispute, OpNext Japan shall nominate one (1) corporate officer of the rank of vice president or higher and HCT shall nominate one (1) corporate officer of the rank of Board Director or higher, which corporate officers shall meet in person and attempt in good faith to negotiate a resolution to the dispute. In the event such nominated individuals are unable to resolve the dispute within forty-five (45) days of receipt by either party of a Dispute Notice, a party shall refer the matter to arbitration (except for actions seeking injunctive relief) pursuant to the arbitration procedures set forth in Exhibit C to this HCT IP License Agreement. In the event that either party submits the dispute to arbitration, both parties shall cooperate in such binding arbitration in accordance with Exhibit C hereto.

Section 13. Non-Compete.

(a) HCT As Wholly-Owned Subsidiary of Hitachi. During the period beginning on the Spin-Off Date and ending at the earlier of: (i) one year after the date of an Initial Public Offering of OpNext; (ii) such time as Hitachi and its Permitted Transferees (as defined in the Stockholders’ Agreement) no longer hold at least a majority of the Voting Securities (as defined in the Stockholders’ Agreement) of OpNext; (iii) termination of this IP License Agreement pursuant to Section 11(a) (the “Non-Competition Period”), HCT, for so long as HCT is a Wholly-Owned Subsidiary of Hitachi, shall not, and shall cause its Wholly-Owned Subsidiaries to not participate or engage in or otherwise invest in, directly or indirectly, any area of the world, the business of designing, developing, manufacturing (or having manufactured), marketing, distributing or selling the following fiber optical products, in each case which are dedicated to use in or intended to be used in telecommunications applications (the “Restricted Products”): transmitters, receivers, transceivers, laser diode modules, photo diode modules, parallel optical interconnectors, lasers, photodiodes, modulators, amplifier modules, optical switches and optical wave guides, including licensing its Intellectual Property related to Restricted Products to third-parties except (a) as part of a global cross-license or (b) any other form of agreement so long as such agreement does not adversely affect the ongoing business of OpNext, other than on behalf of OpNext and its subsidiaries as a sales agent or distributor.

(b) HCT As Subsidiary of Hitachi. During the Non-Competition Period, HCT, for so long as HCT is a Subsidiary of Hitachi but not a Wholly-Owned Subsidiary of Hitachi, shall not, and shall cause its Wholly-Owned Subsidiaries to not, participate or engage in or otherwise invest in, directly or indirectly, any area of the world, the business of designing,

developing, manufacturing (or having manufactured), marketing, distributing or selling Restricted Products.

(i) HCT and its Affiliates shall be permitted to design, develop, manufacture (or have manufactured), market, distribute and sell any Restricted Products that HCT or its Wholly-Owned Subsidiaries were designing, developing, manufacturing (or having manufactured), marketing, distributing or selling on January 1, 2001;

(ii) The provisions of this Section 13 shall not restrict in any manner the activities of (1) any present or future joint ventures to which HCT or any of its Wholly-Owned Subsidiaries is or may be a party or (2) any future entities which may issue or have publicly traded securities outstanding and which are not HCT Subsidiaries; and

(iii) HCT and its Wholly-Owned Subsidiaries may hereafter purchase, or otherwise become affiliated with or participate in, any entity engaged in the design, development, manufacturing (or having manufactured), marketing, distributing and selling of any Restricted Products unless the aggregate gross revenues of such enterprise for its most recently completed fiscal year derived from such activities were greater than either (i) fifteen percent (15%) of the total gross revenues of such enterprise; or (ii) $100 million (and HCT and its Wholly-Owned Subsidiaries may hereafter acquire a controlling interest in any entity that is engaged in such activities, even if the aggregate gross revenues of such enterprise for its most recently completed fiscal year derived from such activities were greater than fifteen percent (15%) of the entity’s total gross revenues and/or $100 million, so long as HCT and its Wholly-Owned Subsidiaries shall use reasonable efforts to divest, as soon as reasonably practicable, a portion of its interest in such enterprise relating to such activities such that the gross revenues test set forth above would not be exceeded after giving effect to such divestiture).

(d) Enforceability. The parties hereto recognize that the laws and public policies of various jurisdictions may differ as to the validity and enforceability of covenants similar to those set forth in this Section 13. HCT acknowledges that the provisions of this Section 13 are reasonable and necessary to protect and preserve the business of OpNext Japan and that OpNext Japan would be irreparably damaged if HCT were to breach the covenants set forth in this Section 13. It is the intention of the parties that the provisions of this Section 13 be enforced to the fullest extent permissible under the laws and policies of each jurisdiction in which enforcement may be sought, and that the unenforceability (or the modification to conform to such laws or policies) of any provisions of this Section 13 shall not render unenforceable, or impair, the remainder of the provisions of this Section 13. Accordingly, if any provision of this Section 13 shall be determined to be invalid or unenforceable, such invalidity or unenforceability shall be deemed to apply only with respect to the operation of such provision in the particular jurisdiction in which such determination is made and not with respect to any other provision or jurisdiction.

(e) Injunctive Relief. The parties hereto acknowledge and agree that any remedy at law for any breach of the provisions of this Section 13 would be inadequate, and HCT

hereby consents to the granting by any court of an injunction or other equitable relief, without the necessity of actual monetary loss being proved, in order that the breach or threatened breach of such provisions may be effectively restrained.

(f) No Restriction. The parties acknowledge that nothing in this Section 13 is intended to restrict HCT or any of its Affiliates from continuing or seeking to do business with any Person who is a customer or supplier of OpNext Japan, subject to compliance with the noncompetition provisions of this Section 13.

Section 14. Assignment. Except as set forth below, this HCT IP License Agreement and any rights and obligations hereunder shall not be assignable or transferable by OpNext Japan or HCT (including by operation of law in connection with a merger or sale of stock, or sale of substantially all the assets, of OpNext Japan or HCT) without the prior written consent of the other party and any purported assignment without such consent shall be void and without effect.

Section 15. Third-Party Beneficiaries. OpNext Japan and HCT acknowledge and agree that this HCT IP License Agreement is intended not only for the benefit of themselves, their Subsidiaries and for purposes of Section 3(c)(ii), 4(c)(ii) and 7(b)(iii) their Minority-Owned Affiliates but also for the benefit of OpNext and OpNext’s Subsidiaries and Minority-Owned Affiliates.

Section 16. Survival of Representations and Warranties. The representations and warranties contained in this HCT IP License Agreement and in any other document delivered in connection herewith shall terminate at the close of business on July 31, 2003.

Section 17. Expenses. Whether or not the transactions contemplated hereby are consummated, and except as otherwise specifically provided in this HCT IP License Agreement, all costs and expenses incurred in connection with this HCT IP License Agreement and the transactions contemplated hereby shall be paid by the party incurring such costs or expenses.

Section 18. Export Control. Each party shall comply or have its Subsidiaries or Affiliates comply with any applicable export laws and regulations and obtain any and all export licenses and/or governmental approvals, if necessary. In the event a licensee (under Sections 2, 3, 4 and 5 above) is unable to obtain any required export license or other governmental approval, and as a result the licensor (under Sections 2, 3, 4 and 5 above) suffers or will suffer irreparable harm as a result of the licensee’s failure, the parties acknowledge and agree that money damages would be inadequate and that the licensor shall be entitled to obtain injunctive or other similar equitable remedies with respect to any such breach.

Section 19. Amendment and Waiver. No amendment of any provision of this HCT IP License Agreement shall be valid unless the same shall be in writing and signed by OpNext Japan and HCT. The failure of any party to enforce any of the provisions of this HCT IP License Agreement shall in no way be construed as a waiver of such provisions and shall not affect the right of such party thereafter to enforce each and every provision of this HCT IP License Agreement in accordance with its terms.

Section 20. Notices. Any notice provided for in this HCT IP License Agreement shall be in writing and shall be either personally delivered, mailed first class mail (postage prepaid) or sent

by reputable overnight courier service (charges prepaid) to the parties at the address set forth below or at such address or to the attention of such other person as the recipient party has specified by prior written notice to the sending party.

Section 21. Interpretation. The headings and captions contained in this HCT IP License Agreement, in any Exhibit or Schedule hereto and in the table of contents to this HCT IP License Agreement are for reference purposes only and do not constitute a part of this HCT IP License Agreement.

Section 24. Schedules or Exhibits. The disclosures set forth in any of the Schedules or Exhibits attached hereto that related to any exception to a particular representation and warranty made hereunder shall be taken to relate to each other Schedule or Exhibit setting forth an exception to a representation and warranty made hereunder to the extent it is reasonable to expect that such disclosure relates to such other representation and warranty. The inclusion of information in the Schedules or Exhibits hereto shall not be construed as an admission that such information is material to the HCT Transferred IP, the Business or HCT. In addition, matters reflected in the Schedules or Exhibits are not necessarily limited to matters required by this HCT IP License Agreement to be reflected in such Schedules or Exhibits. Such additional matters are set forth for informational purposes only and do not necessarily include other matters of a similar nature.

they and their respective counsel have reviewed, negotiated and adopted this HCT IP License Agreement as the joint agreement and understanding of the parties, and the language used in this HCT IP License Agreement shall be deemed to be language chosen by the parties hereto to express their mutual intent and no rule of construction shall be applied against any Person.

Section 26. Severability. Whenever possible, each provision of this HCT IP License Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this HCT IP License Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability shall not affect the validity, legality or enforceability of any other provision of this HCT IP License Agreement in such jurisdiction or affect the validity, legality or enforceability of any provision in any other jurisdiction, but this HCT IP License Agreement shall be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or unenforceable provision had never been contained herein.

Section 27. Governing Law. This HCT IP License Agreement shall be governed by and construed in accordance with the laws of Japan without giving effect to any choice-of-law or conflict-of-law provision or rule (whether of Japan or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than Japan.

At the request of any party hereto or to any such agreement or instrument, each other party hereto or thereto shall reexecute original forms thereof and deliver them to all other parties. No party hereto or to any such agreement or instrument shall raise the use of a facsimile machine to deliver a signature or the fact that any signature or agreement or instrument was transmitted or communicated through the use of a facsimile machine as a defense to the enforceability of a contract and each such party forever waives any such defense.
