EX-10.18: OPNEXT JAPAN, INC. INTELLECTUAL PROPERTY LICENSE AGREEMENT

               (iii) Notwithstanding Section 7(c)(ii), to the extent that after the Second Closing Date, Hitachi desires to disclose to Hitachi’s sublicensed Subsidiaries (that are not Wholly-Owned Subsidiaries), sublicensed Affiliates (including Minority-Owned Affiliates) and/or suppliers (i) OpNext Japan IP and/or (ii) any information furnished to Hitachi pursuant to this IP License Agreement that Hitachi reasonably understands to be proprietary or confidential in nature and any confidential information relating to the Business that Hitachi did not disclose to its sublicensed Subsidiaries (that are not Wholly-Owned Subsidiaries), sublicensed Minority-Owned Affiliates and/or suppliers prior to the Second Closing Date, Hitachi shall notify OpNext Japan of such desire and propose the terms and conditions of an appropriate nondisclosure agreement into which OpNext Japan and the corresponding Hitachi sublicensee may enter. 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 Hitachi sublicensee; (ii) propose reasonably modified terms and conditions of the nondisclosure agreement under which OpNext Japan will provide the requested confidential information to Hitachi’s sublicensee; or (iii) commence discussions with Hitachi 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 B hereto. In the event that either party submits the dispute to arbitration, both parties shall cooperate in such binding arbitration in accordance with Exhibit B.

          (d) OpNext Japan’s and Hitachi’s Trademark, Trade Names, etc. If necessary, OpNext Japan and Hitachi may negotiate in good faith the terms and conditions under which Hitachi 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 Second Closing Date.

          (e) Taxes. Hitachi will be responsible for the payment of any taxes or duties required in connection with the licensing and sublicensing of the Licensed IP and Third Party License Agreements that are incurred on or prior to the Second Closing Date.

          (f) New Product Clearance Searches. In accordance with Hitachi’s ordinary business practice for new product release searches, Hitachi has conducted appropriate patent clearance searches during the design process and prior to putting the 2.5G and 10G products on the market, and based upon the information obtained during such clearance searches Hitachi does not believe there is a likelihood that the 2.5G or 10G products that are on the market as of the Second Closing Date infringe the intellectual property of any third party in such markets in which such products have been introduced. After the Second Closing, Hitachi shall cooperate with OpNext Japan to complete additional clearance searches for the 2.5G, 10G and 40G products in jurisdictions in which such products will be marketed. If during such clearance searches, the parties discover that either the 2.5G, 10G or 40G product infringes a third party’s intellectual property in such jurisdictions, the parties shall consult and cooperate with each other in determining how to respond to the infringing activities.

Section 8. Representations and Warranties of OpNext Japan. OpNext Japan hereby represents and warrants to Hitachi as follows:

          (a) Authority. OpNext Japan is a corporation duly organized under the laws of Japan. OpNext Japan has all requisite corporate power and authority to enter into this IP License Agreement and to consummate the transactions contemplated hereby. All corporate acts and other proceedings required to be taken by OpNext Japan to authorize the execution, delivery and performance of this IP License Agreement and the consummation of the transactions contemplated hereby have been duly and properly taken. This IP License Agreement has been duly executed and delivered by OpNext Japan and constitutes the valid and binding obligation of OpNext Japan, enforceable against OpNext Japan in accordance with its terms.

          (b) No Conflicts. The execution and delivery by OpNext Japan of this IP License Agreement do not, and the consummation by OpNext Japan of the transactions contemplated hereby and compliance by OpNext Japan with the terms hereof do not and shall not: (i) conflict with or result in a breach of the terms, conditions or provisions of; (ii) constitute a default under; (iii) result in the creation of any lien, security interest, charge or encumbrance upon OpNext Japan’s capital stock or assets under; (iv) give any third party the right to modify, terminate or accelerate any obligation under; (v) result in a violation of; or (vi) require any authorization, consent, approval, exemption or other action by or notice or declaration to, or filing with, any court or administrative or governmental body or agency pursuant to the charter documents of OpNext Japan, or any law, statute, rule or regulation to which OpNext Japan is subject, or any agreement, instrument, order, judgment or decree to which OpNext Japan is subject.

          (c) Litigation, etc. There are no actions, suits, proceedings, orders, investigations or claims pending or, to the best of OpNext Japan’s Knowledge, threatened against OpNext Japan, at law or in equity, before or by any governmental department, commission, board, bureau, agency or instrumentality (including any actions, suits, proceedings or investigations with respect to the transactions contemplated by this IP License Agreement) or any facts that are known by OpNext Japan to form a reasonable basis for any such action, suit, proceeding, order, investigation or claim which, in the case of any of the foregoing items, could reasonably be expected to have Material Adverse Effect, on the ability of OpNext Japan to consummate the transactions contemplated hereby.

Section 9. Covenants of OpNext Japan. OpNext Japan covenants as follows:

          (a) Confidentiality

               (i) With respect to any information furnished to OpNext Japan pursuant to the Business Transfer Agreement, the Stock Contribution Agreement or this IP License Agreement, which OpNext Japan reasonably understands to be proprietary or confidential in nature and any confidential information relating to the Business, including Assigned IP, Licensed IP and Third Party License Agreements, OpNext Japan shall maintain the confidentiality of all such information in accordance with OpNext Japan’s policies for the protection of its own nonpublic information (which policies shall provide at least reasonable protection).

               (ii) The limitations set forth in this Section 9(a) shall not apply with respect to the disclosure of any information: (i) to OpNext Japan’s employees, auditors, counsel,

other professional advisors, sublicensees of OpNext Japan authorized pursuant to the terms of Section 3(c) or suppliers, if OpNext Japan or its sublicensees authorized pursuant to the terms of Section 3(c), in its sole discretion, determines that it is reasonably necessary for such party to have access to such information, provided that any such Person agrees to be bound by the provisions of this Section 9(a) to the same extent as OpNext Japan; (ii) as has become or previously was generally available to the public other than by reason of a breach of this Section 9(a) by OpNext Japan or has become available to OpNext Japan on a non-confidential basis after the Second Closing Date; (iii) as may be required or appropriate in any report, statement or testimony submitted to any municipal, state or federal regulatory body having or claiming to have jurisdiction over OpNext Japan (it being understood that, to the extent practicable, OpNext Japan shall provide Hitachi prompt notice to any such event and cooperate in good faith to enable Hitachi to participate to protect its interest in such confidential information); (iv) as may be required or appropriate in response to any summons or subpoena or in connection with any litigation; and (v) in order to comply with any law, order, regulation or ruling applicable to OpNext Japan. In connection with Transferred Employees (as defined in the Stock Contribution Agreement), OpNext Japan will use its Commercially Reasonable Efforts, at Hitachi’s request and at OpNext Japan’s expense, to enforce existing confidentiality agreements and rights under United States or Japanese law requiring employees to keep trade secrets confidential, and to assign Intellectual Property rights to OpNext Japan.

          (b) No Additional Representations. OpNext Japan acknowledges that neither Hitachi nor any other Person has made any representation or warranty, express or implied, as to the accuracy or completeness of any information regarding the Licensed IP or Third Party License Agreements except as expressly set forth in this IP License Agreement or the Schedules and Exhibits hereto. Without limiting the generality of the foregoing, Hitachi makes no representation or warranty with respect to the Licensed IP or Third Party License Agreements, 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 Licensed IP or Third Party License Agreements and, except for the express representations and warranties of Hitachi contained in Section 6, OpNext Japan takes the Licensed IP or Third Party License Agreements on an “as is” and “where is” basis.

          (c) Covenant Not to Sue. OpNext Japan herewith covenants not to sue Hitachi for infringement of any Intellectual Property related to the Business, throughout the world. OpNext Japan also covenants not to sue sublicensees of Hitachi authorized pursuant to the terms of Sections 2(a) and 4(b) or customers of Hitachi for infringement of any Intellectual Property related to the Business throughout the world; provided, however, covenants not to sue customers of Hitachi shall be applied in accordance with the “exhaustion doctrine” such that it only extends to products or methods provided by Hitachi to customers and shall not extend to any portions of any systems or subsystems or any other customer’s products or methods that incorporate such products or methods provided by Hitachi, to the extent such portions are not covered by OpNext Japan IP or Assigned IP.

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

          (a) Consents. OpNext Japan acknowledges that certain consents to the transactions contemplated by this IP License Agreement may be required from parties to Third Party License Agreements and such consents have not been obtained. OpNext Japan agrees that Hitachi and its Minority-Owned Affiliates shall not have any liability whatsoever to OpNext

Japan arising out of or relating to the failure to obtain any consents that may have been or may be required in connection with the transactions contemplated by this Agreement or because of the default, acceleration or termination of any contract as a result thereof. OpNext Japan further agrees that no representation, warranty or covenant of Hitachi contained herein shall be breached or deemed breached and no condition of OpNext Japan shall be deemed not to be satisfied as a result of the failure to obtain any consent or as a result of any such default, acceleration or termination or any lawsuit, action, claim, proceeding or investigation commenced or threatened by or on behalf of any Person arising out of or relating to the failure to obtain any consent or any such default, acceleration or termination. At OpNext Japan’s written request prior to the Second Closing, Hitachi shall cooperate with OpNext Japan in any reasonable manner in connection with OpNext Japan’s obtaining any such consents; provided, however, that such cooperation shall not include any requirement of Hitachi to expend money, commence any litigation or offer or grant any accommodation (financial or otherwise) to any Person.

          (b) Non-Transferred License Agreements. With respect to any Third Party License Agreement that may not be properly licensed to OpNext Japan because of the failure to obtain a required consent (“Non-Transferred License Agreements”), with respect to which OpNext Japan requests Hitachi’s cooperation and with respect to which Hitachi and OpNext Japan are unable to obtain a separate agreement between OpNext Japan and the other party or parties, OpNext Japan shall have the right to require that Hitachi use Commercially Reasonable Efforts to perform any such Non-Transferred License Agreements, to the extent it relates to the Business, as agent for and for the account of OpNext Japan, for a period up to six (6) months following the Second Closing Date; provided that OpNext Japan shall indemnify Hitachi for any and all costs, expenses, losses and liabilities incurred by Hitachi or any of its Affiliates in connection with taking such action.

          (c) 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 IP License Agreement, and use Commercially Reasonable Efforts not to issue any news releases or public statements inconsistent with results of such consultations. Subject to applicable laws or the rules of any applicable securities exchange, each party shall use Commercially Reasonable Efforts to enable the other party to review and comment on all such news releases prior to the release thereof.

          (d) Commercially Reasonable Efforts. Subject to the terms of this IP License Agreement, each party will use its Commercially Reasonable Efforts to satisfy all of the conditions set forth in this IP License Agreement and to cause the Second Closing and this IP License Agreement to occur.

          (e) Injunctive Relief. The parties acknowledge and agree that money damages would be inadequate to remedy any breach of the confidentiality obligations in Sections 7(c) 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. Indemnification.

          (a) Previously Disclosed Claims. Notwithstanding anything to the contrary herein, with respect to the written claims of Intellectual Property infringement previously disclosed, in January 2001, to the counsel of OpNext, Inc., OpNext Japan, their respective Subsidiaries and the Clarity Parties (the “OpNext Parties”), Hitachi shall defend and indemnify

the OpNext Parties with respect to any claims or Losses suffered or incurred by the OpNext Parties as a result of or arising from such previously written claims regardless of the timing of such claims or Losses, and shall ensure that such claims will be resolved in a manner that does not adversely affect the ongoing business of OpNext Japan. Furthermore, none of the limitations or other provisions set forth in Section 11(f) below will apply to the foregoing indemnification obligations. Hitachi shall consult and cooperate with OpNext Japan in determining whether any claim directly related to the previously disclosed claims referenced to in the preceding sentences shall be covered by the indemnity set forth in this section.

          (b) Intellectual Property Indemnification and Defense.

               (i) Before Second Closing. With respect to third party patent and copyright infringement claims and trade secret misappropriation claims regarding products, processes or methods related to the Business as it was conducted prior to the Second Closing, Hitachi shall defend and indemnify OpNext Japan regardless of the timing of such third party’s infringement claim; provided, however, that such infringement is not attributable to any OpNext Japan IP.

               (ii) After Second Closing. (1) With respect to third party patent or copyright infringement claims or trade secret misappropriation claims regarding products, processes or methods related to the Business as it is conducted after the Second Closing, Hitachi and OpNext Japan shall jointly defend such action but only to the extent that such claim involves Assigned IP or Licensed IP; (2) If a third party patent or copyright infringement claim or trade secret misappropriation claim is made against OpNext Japan for a new product design that is developed after the Second Closing Date, Hitachi shall be responsible for the settlement amount of any such claim (provided that prior written approval is obtained) or the resulting liability of any such claim only to the extent such claim results from a product design sold by the Business as of the Second Closing Date, Assigned IP or Licensed IP, while OpNext Japan shall be responsible for the settlement amount of any such claim (provided that prior written approval is obtained) or the resulting liability of any such claim to the extent that it is caused by the product design introduced by OpNext Japan irrespective of whether such OpNext Japan product design is covered by Assigned IP or Licensed IP. For avoidance of doubt and notwithstanding the foregoing, the indemnity under this Section 11(b)(ii) shall not apply to any infringement or misappropriation claims that do not involve such products, processes or methods described above. To the extent there is a dispute regarding the allocation of the parties’ liabilities under this subsection, the parties shall negotiate in good faith, in accordance with the terms set forth in Section 12, what the allocation of liability should be. If the parties are unable to agree even after good faith negotiations, the parties shall submit the issue to arbitration pursuant to the arbitration procedures set forth in Exhibit B hereto. In the event that either party submits the dispute to arbitration, both parties shall cooperate in such binding arbitration in accordance with Exhibit B.

          (c) Indemnification by Hitachi. From and after the Second Closing, Hitachi shall indemnify OpNext Japan and its Affiliates and each of their respective officers, directors, members, stockholders, partners and employees (as applicable) and hold them harmless from any loss, liability, damage or expense (including court costs and reasonable attorneys’ fees) (“Losses”) suffered or incurred by any such Indemnified Party to the extent arising from: (i) any breach of any representation or warranty of Hitachi contained in this IP License Agreement that survives the Second Closing Date; and (ii) any breach of any covenant of Hitachi contained in this IP License Agreement requiring performance before or after the Second Closing Date.

          (d) Indemnification by OpNext Japan. From and after the Second Closing, OpNext Japan shall indemnify Hitachi and its Affiliates and each of their respective officers, directors, members, stockholders, partners and employees (as applicable) against and hold them harmless from any Losses suffered or incurred by any such Indemnified Party to the extent arising from: (i) any breach of any representation or warranty of OpNext Japan contained in this IP License Agreement that survives the Second Closing Date; (ii) any breach of any covenant of OpNext Japan contained in this IP License Agreement requiring performance before or after the Second Closing Date; (iii) and any obligation, liability, action, suit, claim or other proceeding that arises directly or indirectly out of the operation of the Business or use of the Assigned IP or Licensed IP on or after the Second Closing or the manufacture, distribution, marketing or sale of the Products at any time on or after the Second Closing. For avoidance of doubt and notwithstanding the foregoing, the indemnity under this Section 11(d) shall not apply to any infringement or misappropriation claims that are covered under Section 11(b)(ii) above.

          (e) Losses Net of Insurance. The amount of any and all Losses under this Section 11 shall be determined net of any amounts recovered or recoverable by the Indemnified Party under insurance policies with respect to such Losses. Each party hereby waives, to the extent permitted under its applicable insurance policies, any subrogation rights that its insurer may have with respect to any indemnifiable Losses.

          (f) Limitations on Indemnification. Notwithstanding the foregoing, in no event shall either party indemnify the other party under Section 11(b), 11(c)(i) and 11(d)(i) and (iii) of this IP License Agreement or Sections 13(a)(i), 13(a)(v), 13(b), 13(c), 13(d)(i) and 13(d)(vi) (as Sections 13(a) and 13(d) relate to Assigned IP, Licensed IP or any other Intellectual Property relevant to the Business) of the Stock Contribution Agreement for claims brought on or after two (2) years after the Second Closing Date. Neither party shall have any liability under Section 11(b), 11(c)(i) and 11(d)(i) and (iii) of this IP License Agreement or Sections 13(a)(i), 13(a)(v), 13(b), 13(c), 13(d)(i) and 13(d)(vi) (as Sections 13(a) and 13(d) relate to Assigned IP, Licensed IP or any other Intellectual Property relevant to the Business) of the Stock Contribution Agreement, unless the aggregate of all Losses for which the indemnifying party would, but for this proviso, be liable, exceeds on a cumulative basis an amount equal to seven hundred and fifty million yen (¥ 750,000,000.00), and then only to the extent of any such excess; provided further, that the indemnifying party’s liability under Sections 11(b), 11(c)(i) and 11(d)(i) and (iii) of this IP License Agreement or Sections 13(a)(i) and 13(a)(v), 13(b), 13(c) and 13(d)(i) and 13(d)(vi) (as Sections 13(a) and 13(d) relate to Assigned IP, Licensed IP or any other Intellectual Property relevant to the Business) of the Stock Contribution Agreement in the aggregate shall in no event exceed four hundred and twenty-eight point six million dollars ($428.6 million). The parties further agree that neither party shall be entitled to assert any claim against the indemnifying party for indemnification of Losses unless the aggregate Losses asserted in such claim equal or exceed five million yen (¥ 5,000,0000.00). To the extent there is a dispute as to whether an asserted claim (i) exceeds the 5 million yen threshold and/or (ii) exceeds on a cumulative basis an amount equal to seven hundred and fifty million yen (¥ 750,000,000.00)that has not been resolved within thirty (30) days after the claim has been asserted, the parties shall refer the dispute to a partner from an internationally recognized accounting or consulting firm reasonably acceptable to the parties or to any individual from a valuation firm reasonably acceptable to the parties, and such partner or individual shall provide within sixty (60) days a binding resolution to such dispute. The party disputing the sufficiency of the claim shall bear all costs associated with

the resolution of the dispute; provided, however, that if the party disputing the sufficiency of the claim prevails, both parties shall share the costs of resolving such dispute.

          (g) Procedures Relating to Indemnification. In order for a Person (the “Indemnified Party”) to be entitled to any indemnification provided for under this IP License Agreement in respect of, arising out of or involving a claim or demand made by any Person against the Indemnified Party (a “Third Party Claim”), such Indemnified Party must notify the indemnifying party in writing, and in reasonable detail, of the Third Party Claim as promptly as reasonably possible after receipt by such Indemnified Party of notice of the Third Party Claim; provided, however, that failure to give such notification on a timely basis shall not affect the indemnification provided hereunder except to the extent the indemnifying party shall have been actually prejudiced as a result of such failure. Thereafter, the Indemnified Party shall deliver to the indemnifying party, within five (5) Business Days after the Indemnified Party’s receipt thereof, copies of all notices and documents (including court filings and related papers) received by the Indemnified Party relating to the Third Party Claim. If a Third Party Claim is made against an Indemnified Party, the indemnifying party shall be entitled to participate in the defense thereof and, if it so chooses and acknowledges its obligation to indemnify the Indemnified Party therefor, to assume the defense thereof with counsel selected by the indemnifying party and reasonably satisfactory to the Indemnified Party and to settle such suit, action, claim or proceeding in its discretion with a full release of the Indemnified Party and no admission of criminal liability. Notwithstanding any acknowledgment made pursuant to the immediately preceding sentence, the indemnifying party shall continue to be entitled to assert any limitation on its indemnification responsibility contained in Section 11. Should the indemnifying party so elect to assume the defense of a Third Party Claim, the indemnifying party shall not be liable to the Indemnified Party for legal expenses subsequently incurred by the Indemnified Party in connection with the defense thereof unless the indemnifying party has substantially and materially failed to defend, contest or otherwise protest in a timely manner against Third Party Claims. If the indemnifying party assumes such defense, the Indemnified Party shall have the right to participate in the defense thereof and to employ counsel, at its own expense, separate from the counsel employed by the indemnifying party, it being understood, however, that the indemnifying party shall control such defense. The indemnifying party shall be liable for the fees and expenses of counsel employed by the Indemnified Party for any period during which the indemnifying party has not assumed the defense thereof. If the indemnifying party chooses to defend any Third Party Claim, all the parties hereto shall cooperate in the defense or prosecution of such Third Party Claim. Such cooperation shall include the retention and (upon the indemnifying party’s request) the provision to the indemnifying party of records and information that are reasonably relevant to such Third Party Claim, and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. Whether or not the indemnifying party shall have assumed the defense of a Third Party Claim, the Indemnified Party shall not admit any liability with respect to, or settle, compromise or discharge, such Third Party Claim without the indemnifying party’s prior written consent, which consent shall not be unreasonably withheld, unreasonably delayed or unreasonably conditioned.

          (h) Controlling Provision. OpNext Japan, the Clarity Parties and Hitachi acknowledge and agree that the indemnification obligations of Hitachi pursuant to this Section 11 supersede and preempt in their entirety the indemnification obligations of Hitachi contained

in Section 24(d) of the Stock Purchase Agreement to the extent such indemnification obligations cover the same subject matter as the subject matter hereof.

          (i) Duty to Mitigate. With respect to any indemnification provided pursuant to this Section 11, the Indemnified Party shall have the duty to mitigate any damages resulting from such Third Party Claim of infringement or misappropriation. In addition, OpNext Japan shall make Commercially Reasonable Efforts to conduct appropriate clearance searches during the design process and prior to putting a new product on the market in accordance with mutually agreed upon procedures for new product release searches. Within one hundred and eighty (180) days from the Second Closing Date, Hitachi and OpNext Japan shall mutually agree upon the procedures to be adopted for conducting new product release searches. During the design process and prior to putting the 40G products on the market, Hitachi will cooperate with OpNext Japan to conduct appropriate clearance searches. Hitachi shall provide OpNext Japan with copies of the results of searches performed in the past two (2) years by Hitachi with respect to Licensed IP.

Section 12. Dispute Resolution. In the event of any dispute under this 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 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 Hitachi 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 B to this 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 B hereto.

Section 13. Assignment. Except as set forth below, this IP License Agreement and any rights and obligations hereunder shall not be assignable or transferable by OpNext Japan or Hitachi (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 Hitachi) without the prior written consent of the other party and any purported assignment without such consent shall be void and without effect.

Section 14. Third-Party Beneficiaries. OpNext Japan and Hitachi acknowledge and agree that this IP License Agreement is intended not only for the benefit of themselves, their Subsidiaries and for purposes of Section 3(c)(ii), 7(c)(iii) and 10(a) their Minority-Owned Affiliates but also for the benefit of the Clarity Parties, OpNext, Inc. and OpNext, Inc.’s Subsidiaries and Minority-Owned Affiliates.

Section 15. Termination. This Agreement will terminate automatically and be of no further force or effect upon the termination of the Stock Purchase Agreement; provided, however, that the following provisions of this IP License Agreement survive termination of this IP License Agreement: (i) Sections 7(c) and 10(e) relating to the obligation of Hitachi to keep confidential certain information and data and injunctive relief for failure to do same, respectively; (ii) Sections 9(a) and 10(e) relating to the obligation of OpNext Japan to keep confidential certain

information and data and injunctive relief for failure to do same, respectively; (iii) Section 10(c) relating to press releases; (iv) Sections 11(a), 11(b), 11(c), 11(d) and 11(f) relating to indemnification; and (v) Section 17 relating to expenses.

Section 16. Survival of Representations and Warranties. The representations and warranties contained in this IP License Agreement and in any other document delivered in connection herewith shall survive the First Closing and the Second Closing and shall terminate at the close of business on the second (2^nd) anniversary of the Second Closing Date.

Section 17. Expenses. Whether or not the transactions contemplated hereby are consummated, and except as otherwise specifically provided in this IP License Agreement, all costs and expenses incurred in connection with this 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 and 3 above) is unable to obtain any required export license or other governmental approval, and as a result the licensor (under Sections 2 and 3 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 IP License Agreement shall be valid unless the same shall be in writing and signed by OpNext Japan and Hitachi. The failure of any party to enforce any of the provisions of this 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 IP License Agreement in accordance with its terms.

Section 20. Notices. Any notice provided for in this 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. Notices shall be deemed to have been given hereunder on the date delivered when delivered personally, seven (7) days after deposit in the U.S. mail or Japanese mail and three (3) days after deposit with a reputable overnight courier service.

Section 27. Severability. Whenever possible, each provision of this IP License Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this 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 IP License Agreement in such jurisdiction or affect the validity, legality or enforceability of any provision in any other jurisdiction, but this 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.

          For the avoidance of doubt, this IP License Agreement does not grant Hitachi or its Wholly-Owned Subsidiaries the right to sublicense the Assigned IP and Hitachi and its Wholly-Owned Subsidiaries shall not have the right to sublicense the Assigned IP without the prior written consent of OpNext Japan, not to be unreasonably withheld, unreasonably delayed or unreasonably conditioned.

          (2) Section 2 of the IP License Agreement is hereby amended by adding the following clause (c) after clause (b):

          (c) Status of Wholly-Owned Subsidiaries.

               (i) License to Assigned IP. If at any time a Wholly-Owned Subsidiary of Hitachi ceases to remain a Wholly-Owned Subsidiary of Hitachi, Hitachi shall provide written notice of such change to OpNext Japan in accordance with Section 20 of this IP License Agreement and the license under Assigned IP to such Wholly-Owned Subsidiary, shall continue, pursuant to the terms and conditions of this IP License Agreement.

               (ii) Sublicenses. For the avoidance of doubt, this IP License Agreement does not grant Wholly-Owned Subsidiaries of Hitachi the right to sublicense the Assigned IP and an entity that ceases to remain a Wholly-Owned Subsidiary of Hitachi shall not have the right to sublicense the Assigned IP without the prior written consent of OpNext Japan, not to be unreasonably withheld, unreasonably delayed or unreasonably conditioned; provided, however, that to the extent any sublicenses have been granted with OpNext Japan’s prior written consent with respect to the Assigned IP during the time such entity is a Wholly-Owned Subsidiary of Hitachi, such sublicenses shall continue, pursuant to the terms and conditions of this IP License Agreement and such sublicense.

          (3) Section 3 of the IP License Agreement is hereby amended by adding the following clause (h) after clause (g):

          (h) Change in Status. If at any time a Subsidiary, Wholly-Owned Subsidiary or Minority-Owned Affiliate of OpNext Japan or a Subsidiary or Wholly-Owned Subsidiary of OpNext, Inc. ceases to remain a Subsidiary, Wholly-Owned Subsidiary or Minority-Owned Affiliate (as appropriate) to the extent any sublicenses have been granted by OpNext Japan or OpNext, Inc. to such entity with respect to the Licensed IP during the time such entity is such a Subsidiary, Wholly-Owned Subsidiary or Minority-Owned Affiliate (as appropriate) such sublicenses of Licensed IP existing as of the date such entity ceases to remain a Subsidiary, Wholly-Owned Subsidiary or Minority-Owned Affiliate (as appropriate) shall continue, pursuant to the terms and conditions of this IP License Agreement and such sublicense.

               (e) Status of Wholly-Owned Subsidiaries.

               (i) License to OpNext Japan IP. If at any time a Wholly-Owned Subsidiary of Hitachi ceases to remain a Wholly-Owned Subsidiary of Hitachi, Hitachi shall provide written notice of such change to OpNext Japan in accordance with Section 20 of this IP License

Agreement and the license under OpNext Japan IP existing as of the date such Wholly-Owned Subsidiary ceases to remain a Wholly-Owned Subsidiary, shall continue, pursuant to the terms and conditions of this IP License Agreement; provided, however, for any Intellectual Property related to the Business that is developed by OpNext Japan after a Wholly-Owned Subsidiary ceases to remain a Wholly-Owned Subsidiary, the parties shall negotiate in good faith and on commercially reasonable terms a new license governing such Intellectual Property.

               (ii) Sublicenses. For the avoidance of doubt, this IP License Agreement does not grant Wholly-Owned Subsidiaries of Hitachi the right to sublicense the OpNext Japan IP and an entity that ceases to remain a Wholly-Owned Subsidiary of Hitachi shall not have the right to sublicense the OpNext Japan IP without the prior written consent of OpNext Japan, not to be unreasonably withheld, unreasonably delayed or unreasonably conditioned; provided, however, that to the extent any sublicenses have been granted with OpNext Japan’s prior written consent with respect to the OpNext Japan IP during the time such entity is a Wholly-Owned Subsidiary of Hitachi, such sublicenses shall continue, pursuant to the terms and conditions of this IP License Agreement and such sublicense.

          (5) Section 6(e) of the IP License Agreement is hereby amended by deleting it in its entirety and replacing it with the following clause (e):

          (e) Infringement of Licensed IP. To the extent a competitor of the Business is infringing or misappropriating the Licensed IP or any Future Hitachi IP that is licensed to OpNext Japan under Section 3(b) or Section 3(f), respectively, in OpNext Japan’s reasonable business judgment and such infringement is material to the Business, Hitachi, in its sole discretion, will protect OpNext Japan’s interest by either: (i) initiating and maintaining legal proceedings with respect to such alleged infringement or misappropriation against any such Person on behalf of OpNext Japan or (ii) by taking some other appropriate action that will not have a Material Adverse Effect on the ongoing business of OpNext Japan; provided that with respect to clauses (i) and (ii), both parties shall consult and cooperate with each other in determining how to respond to the infringing activities. For the avoidance of doubt, Hitachi may or may not consult with OpNext Japan prior to determining whether to pursue (i) or (ii). Upon the resolution of such infringement by settlement or otherwise, any damages, profits and awards of whatever nature recoverable for such infringement shall, after deducting the parties’ expenses, be reasonably allocated between the parties based on the facts and circumstances of the infringement. Both parties will reasonably consider the option of settling such matter by granting a sublicense of all or portion of the Licensed IP and any Future Hitachi IP that is licensed to OpNext Japan.

          (6) Section 7 of the IP License Agreement is hereby amended by adding the following clause (g) after clause (f):

          (g) Guaranty.

          (i) Hitachi will use reasonable best efforts to cause its Wholly-Owned Subsidiaries (for so long as they are Wholly-Owned Subsidiaries) to comply with the terms and conditions of this IP License Agreement and Hitachi shall be liable for any breach of such terms and conditions.

          (ii) Hitachi will use reasonable best efforts to cause its Wholly-Owned Subsidiaries that cease to remain Wholly-Owned Subsidiaries to comply with the terms and conditions of this IP License Agreement applicable to such entities and Hitachi shall be liable for any breach of such terms and conditions.

          Section 33. Hitachi Communication Technologies. For purposes of this IP License Agreement, the defined term “Wholly-Owned Subsidiary” shall not include Hitachi’s Wholly-Owned Subsidiary, Hitachi Communication Technologies, Ltd.

Section 3. No Other Amendments.

          Except as expressly set forth herein, all other terms and conditions of the IP License Agreement shall remain unmodified, in full force and effect and shall apply to this Amendment.

Section 4. Governing Law.

          This Amendment 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 of Japan. Regardless of the law applied, because this contract is in English, the terms and conditions of this contract will be interpreted in

accordance with the meaning of the words in American colloquial English, notwithstanding any meaning of any word when translated into its Japanese equivalent.

Section 5. Dispute Resolution.

          In the event of any dispute under this Amendment, as a condition precedent to either party seeking arbitration, in connection therewith, the parties will attempt to resolve such dispute by good faith negotiations (except for actions seeking injunctive relief). Such negotiations shall first involve the individuals designated by the parties as having general responsibility for the 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 Hitachi 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 the corporate executives are unable to resolve the dispute within forty-five (45) days of receipt by either party of a Dispute Notice, a party may refer the matter to arbitration (except in the case of disputes arising under Section 11(c) of the IP License Agreement for which the parties may seek injunctive relief). In the event that either party submits the dispute to arbitration, both parties shall cooperate in such binding arbitration in accordance with Exhibit B to the IP License Agreement.

Section 6. Interpretation.

          The headings and captions contained in this Amendment and in any Exhibit are for reference purposes only and do not constitute a part of this Amendment. The use of the word “including” herein shall mean “including without limitation.”

Section 7. Severability.

          Whenever possible, each provision of this Amendment shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Amendment 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 Amendment in such jurisdiction or affect the validity, legality or enforceability of any provision in any other jurisdiction, but this Amendment shall be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or unenforceable provision had never been contained herein.

Section 8. Counterparts.

          This Amendment may be executed in one or more counterparts, each of which shall be an original and all of which taken together shall constitute one and the same agreement.

          WHEREAS, Hitachi and Opnext Japan desire to enter into this Amendment to further amend the IP License Agreement as set forth herein.

          NOW, THEREFORE, in consideration of the mutual covenants contained herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties to this Amendment hereby agree as follows:

In the event the breach is a curable breach that cannot be cured within the Cure Period but with respect to which Opnext Japan has instituted steps necessary to remedy the default and is thereafter diligently pursuing such cure, both parties shall negotiate to determine whether further pursuit of such cure is reasonable. 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 B 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, (i) the parties agree that the matter shall be referred to arbitration pursuant to the arbitration procedures set forth in Exhibit B hereto to determine the appropriate remedy, and (ii) Opnext Japan shall provide an on-going plan to address the prevention of such a breach occurring again reasonably acceptable to Hitachi within sixty (60) days of written notice of the breach and shall implement and comply with such plan within the time period set forth in such plan.

          (6) Section 3(c)(iii) of the IP License Agreement is hereby amended by deleting it in its entirety and replacing it with the following Section 3(c)(iii):

With respect to Hitachi’s exercise of one (1) of the five (5) foregoing options, Hitachi agrees to provide consents to and/or notify the applicable Opnext Entity of Hitachi’s proposed modifications within fifteen (15) Business Days of receipt of the sublicense terms and conditions from the applicable Opnext Entity. In the event that Hitachi exercises one (1) of the five (5) foregoing options, 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 Hitachi’s provision of such a response to the applicable Opnext Entity; provided, however, Hitachi shall not contact the applicable Opnext Entity customers that are the subject of negotiations between Hitachi and Opnext Japan, without the prior consent of the applicable Opnext Entity prior to the resolution of such negotiations. 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 B hereto. In the event that either party submits the dispute to

arbitration, both parties shall cooperate in such binding arbitration in accordance with Exhibit B.

          In addition, Hitachi agrees that for the avoidance of doubt the rights provided for in this Section 3(c)(iii) are in no way meant to limit the rights of Opnext Japan in Section 3(b)(i).

In the event the breach is a curable breach that cannot be cured within the Cure Period but with respect to which Hitachi has instituted steps necessary to remedy the default and is thereafter diligently pursuing such cure, both parties shall negotiate to determine whether further pursuit of such cure is reasonable.

          (e) Termination of Obligations. The obligations set forth in this Section 5 shall terminate upon the later of: (i) the date that is one hundred and eighty (180) days after the date when Opnext, Inc. ceases to be a Subsidiary of Hitachi, and (ii) the first anniversary of any Initial Public Offering of Opnext, Inc. (the “Negotiation Period”), provided that, if negotiations are ongoing with respect to any license and within thirty (30) days of the end of the Negotiation Period, Opnext Japan provides a written request to Hitachi for an extension of the Negotiation Period for such time as is required to complete negotiations for such license, but no longer than one hundred and eighty (180) days, the Negotiation Period for such license shall automatically be extended for such requested time period, not to exceed one hundred and eighty (180) days. Additionally, for so long as Hitachi owns twenty percent (20%) or more of the voting securities of Opnext, Inc., Opnext Japan may submit a written request to Hitachi once every six (6) month period regarding whether Hitachi has entered into (or has entered into negotiations for) a Future Third Party License Agreement with a specified third party, and Hitachi will confirm whether or not Hitachi has entered into (or has entered into negotiations for) a Future Third Party License Agreement with such specified third party.

          (11) Section 6 of the IP License Agreement is hereby amended by adding the following Section 6(f):

          (f) Intellectual Property. Hitachi represents and warrants that except as set forth in Exhibit A to this Amendment, between the Second Closing and the Amendment Date, Hitachi has not received any written notice alleging that Opnext, Inc. or any of its subsidiaries has misappropriated, infringed or otherwise violated the Intellectual Property of any third party.

          (12) Section 13 of the IP License Agreement is hereby amended by adding the following clause at the end:

; provided, however, that this IP License Agreement, in its entirety, shall be assignable by Opnext Japan (or any successor to Opnext Japan) to Opnext, Inc. or any Wholly-Owned Subsidiary of Opnext, Inc. For the avoidance of doubt, the parties agree that an Initial Public Offering (as defined in the Stockholders’ Agreement) shall not require the consent Hitachi.

          (13) Section 15 of the IP License Agreement is hereby amended by adding the following clause at the end:

and (vi) any licenses to Intellectual Property that exists and is subject to any licenses granted hereunder prior to the effective date of any termination of this IP License Agreement.

          (14) A new Section 36 is hereby added to the IP License Agreement which provides as follows:

Section 36. Bankruptcy. The parties agree that if a party becomes a debtor or debtor-in-possession under Title 11 of the United States Code (the “Bankruptcy Code”): (i) in the event of a rejection or proposed rejection of this IP License Agreement under Section 365 of the Bankruptcy Code, any and all rights licensed pursuant to this IP License Agreement shall be deemed to fall within the definition of “intellectual property” under Section 101 of the Bankruptcy Code and, in connection therewith, Section 365(n) of the Bankruptcy Code shall be implicated by such rejection or proposed rejection; and (ii) notwithstanding Section 365(c) of the Bankruptcy Code or applicable non-bankruptcy law which prohibits, restricts or conditions the assignment or assumption of this IP License Agreement or any of the rights therein, but subject to the debtor-in-possession or trustee, as applicable, otherwise complying with the requirements of Section 365 of the Bankruptcy Code for assumption, the debtor-in-possession or trustee in bankruptcy may assume this IP License Agreement. The parties agree that if a party files for bankruptcy under the laws of any other jurisdiction, the terms of this section will apply to the extent necessary to preserve the rights provided in this section.

          (15) A new Section 37 is hereby added to the IP License Agreement which provides as follows:

Section 37. Injunctive Relief. Each party acknowledges and agrees that the other party’s Intellectual Property and Confidential Information are valuable property of such other party and that a material breach of this IP License Agreement (including unauthorized use of Intellectual Property or disclosure of Confidential Information) will cause irreparable injury for which the injured party does not have an adequate remedy at law and for which monetary remedies are not sufficient. Each party shall be entitled to seek equitable relief (including the

granting of injunctive relief in that party’s favor) without the obligation of posting a bond if the other party makes or threatens a material breach of this IP License Agreement (including unauthorized use of Intellectual Property or disclosure of Confidential Information). Each party agrees that equitable relief is not exclusive of other remedies to which the other party may be entitled at law or in equity as a result of any such material breach of this IP License Agreement (including any unauthorized use of Intellectual Property or disclosure of Confidential Information).

Section 3. No Other Amendments.

          Except as expressly set forth herein, all other terms and conditions of the IP License Agreement shall remain unmodified, in full force and effect and shall apply to this Amendment.

Section 4. Governing Law.

          This Amendment 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 of Japan. Regardless of the law applied, because this contract is in English, the terms and conditions of this contract will be interpreted in accordance with the meaning of the words in American colloquial English, notwithstanding any meaning of any word when translated into its Japanese equivalent.

Section 5. Dispute Resolution.

          In the event of any dispute under this Amendment, as a condition precedent to either party seeking arbitration, in connection therewith, the parties will attempt to resolve such dispute by good faith negotiations (except for actions seeking injunctive relief). Such negotiations shall first involve the individuals designated by the parties as having general responsibility for the 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 Hitachi 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 the corporate executives are unable to resolve the dispute within forty-five (45) days of receipt by either party of a Dispute Notice, a party may refer the matter to arbitration (except in the case of disputes arising under Section 11(c) or Section 36 of the IP License Agreement for which the parties may seek injunctive relief). In the event that either party submits the dispute to arbitration, both parties shall cooperate in such binding arbitration in accordance with Exhibit B to the IP License Agreement.

Section 6. Interpretation.

          The headings and captions contained in this Amendment and in any Exhibit are for reference purposes only and do not constitute a part of this Amendment. The use of the word “including” herein shall mean “including without limitation.”

Section 7. Severability.

          Whenever possible, each provision of this Amendment shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Amendment 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 Amendment in such jurisdiction or affect the validity, legality or enforceability of any provision in any other jurisdiction, but this Amendment shall be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or unenforceable provision had never been contained herein.

Section 8. Order of Precedence. To the extent of a conflict between this Amendment and the First Amendment, the terms and conditions of this Amendment shall control.

Section 9. Counterparts.

          This Amendment may be executed in one or more counterparts, each of which shall be an original and all of which taken together shall constitute one and the same agreement.
