(b) Future Research and Development. During the term of this R&D Agreement, Hitachi will provide R&D Support, as requested, to OpNext Japan for Future R&D Projects in accordance with the R&D Procedures. Hitachi will provide such R&D Support consistent with the following:

(i) Meetings. Hitachi and OpNext Japan will hold quarterly joint review meetings to determine and update the R&D Plan for Future R&D Projects.

(ii) Requests and Forecasts. Based on the R&D Plan developed in accordance with the R&D Procedures, OpNext Japan will require assistance on a binding basis from Hitachi on specific Future R&D Projects for the upcoming twelve (12) month period. OpNext Japan will also provide Hitachi with a non-binding forecast of Future R&D Projects that OpNext Japan expects to request from Hitachi for the twelve (12) month period following such twelve (12) month period.

(iii) Support.

Hitachi will use Commercially Reasonable Efforts to be able to support the balance of the non-binding forecast.

(i) Assignment and License. Hitachi shall assign, and does hereby assign, to OpNext Japan all right, title and interest in and to all Intellectual Property resulting from the Current R&D Projects and which shall be listed on Exhibit B, which is capable of assignment, to the extent such assignment did not occur under the Business Transfer Agreement. Such Intellectual Property shall be deemed to be OpNext Japan R&D IP. Hitachi also shall license, and does hereby license effective as of the First Closing Date, all Intellectual Property resulting from the Current R&D Projects, which has not been assigned and is not capable of assignment, to OpNext Japan on a fully paid-up, non-exclusive, perpetual and irrevocable basis, to use, make, have made, sell, advertise, offer to sell, lease, import, export and supply products and services throughout the world, unless otherwise terminated according to the provisions of this R&D Agreement. Such licensed

- 10 -

Intellectual Property shall be deemed to be Licensed IP subject to the terms and conditions of the IP License Agreement.

(ii) Termination Conditions. Such license shall not be terminated or its exploitation enjoined, until and unless: (i) OpNext Japan has committed a material breach of its obligations under this R&D Agreement, Hitachi has given written notice of such breach to OpNext Japan and such breach remains uncured after sixty (60) days of receiving notice of such breach (the “Cure Period”), or, in the case of a breach, which cannot be cured within such Cure Period, OpNext Japan has not instituted within such Cure Period steps necessary to remedy the default and/or thereafter has not diligently pursued the same to completion; or (ii) OpNext Japan has committed an incurable material breach. 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 E 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 E 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 E.

(iii) Review of Obligations. The obligations set forth in this Section 2(c) shall expire on the tenth (10^th) anniversary of the Second Closing Date; provided, however, that the license under OpNext Japan R&D IP existing as of the tenth (10^th) anniversary of the Second Closing Date shall continue, under reasonable terms and conditions to be agreed between the parties, until the expiration of all of such OpNext Japan R&D IP. Notwithstanding the foregoing, if one (1) of the conditions set forth in Section 2(c)(ii) is met, Hitachi may elect to be completely relieved of its obligations set forth in this Section 2(c). If Hitachi elects to be relieved of its obligations under this Section 2(c), the parties shall renegotiate in good faith and on commercially reasonable terms a new license governing the OpNext Japan R&D IP.

Section 3. Exclusions from Research and Development Obligations

(a) Hitachi. Nothing contained in this R&D Agreement shall limit in any way Hitachi’s ability to continue to conduct research and development activities for other Hitachi business units, including its Affiliates and Subsidiaries, including any fiber optical component business (e.g., semiconductors and cable) subject to the Nonsolicitation or Noncompetition provision in Section 12 of the Stockholders’ Agreement; provided, however, the terms and conditions of this R&D Agreement shall be subject to the terms and conditions of any existing agreements related to the governmental R&D projects, the joint R&D projects with national and public universities or private universities, the R&D projects requested by other Hitachi Subsidiaries or the joint R&D projects with any other agency or organization (collectively, the “Existing R&D Agreements”). Prior to the commencement of any R&D Project, Hitachi shall disclose to OpNext Japan any restrictions contained in the Existing R&D Agreements related to such R&D Project.

- 11 -

(b) OpNext Japan. Nothing in this R&D Agreement shall in any way limit OpNext Japan’s ability to conduct its own, or utilize other third parties to conduct on its behalf, research and development projects.

Section 4. Ownership of Intellectual Property Rights.

(a) OpNext Japan’s Intellectual Property. OpNext Japan will own all right, title and interest, throughout the world in and to OpNext Japan R&D IP. OpNext Japan shall have the right to apply, in its own name and at its own expense, for Intellectual Property protection in the OpNext Japan R&D IP. Hitachi shall cooperate with OpNext Japan in a reasonable manner in obtaining such protection, including, obtaining signatures of Hitachi Inventors and/or officials on official papers.

(b) Hitachi’s R&D Intellectual Property. Hitachi will solely own all Intellectual Property rights that result from all of its other research and development projects including the Intellectual Property referenced in Section 4)(c)(i), excluding Jointly Developed Intellectual Property and/or OpNext Japan R&D IP (“Hitachi R&D IP”). Hitachi shall have the right to apply, in its own name and at its own expense, for Intellectual Property protection in Hitachi R&D IP and, if requested, OpNext Japan shall cooperate with Hitachi in any reasonable manner in obtaining such protection, including, obtaining signatures of OpNext Japan Inventors and/or officials on official papers.

(c) Jointly Developed Intellectual Property. All right, title and interest in and to Jointly Developed Intellectual Property, other than OpNext Japan R&D IP and Hitachi R&D IP, shall be determined in accordance with this Section 4(c).

(i) Hitachi Owned. If the R&D Project is jointly funded by OpNext Japan and Hitachi, unless (ii) or (iii) below applies, the resulting Intellectual Property will be treated as Hitachi R&D IP in accordance with Section 4(b) and will be solely owned by Hitachi.

(ii) Jointly Owned.

(1) If the R&D Project is jointly funded by the parties and either: (1) OpNext Japan contributes fifty percent (50%) or more of the New Development Costs to the R&D Project; or (2) OpNext Japan contributes less than fifty percent (50%) of the New Development Costs to the R&D Project but the parties determine through good faith negotiations that OpNext Japan contributed to the R&D Project in some other fashion, and in both (1) and (2) above the resulting Intellectual Property can clearly be identified with reasonable certainty as that resulting from such R&D Project, then such Intellectual Property shall be deemed Jointly Developed Intellectual Property and shall be owned jointly by the parties and either party may practice such Jointly Developed Intellectual Property without an accounting or compensation to, or the consent of, the other party. Except as set forth in Section 4(c)(iii) below, if either party desires to license any of its rights to the Jointly Developed Intellectual Property herein to a third party, it shall obtain the prior written consent of the other party hereto. Each party shall have the right to apply, in both parties’ names, for Intellectual Property protection in the Jointly Developed Intellectual Property. The parties shall agree on the proper way and strategy for proceeding with all

- 12 -

protection of the Jointly Developed Intellectual Property in accordance with the R&D Procedures. All expenses incurred in obtaining and maintaining Intellectual Property protection in the Jointly Developed Intellectual Property shall be equally shared by the parties. In the event that one (1) of the parties elects not to seek or maintain patent or other intellectual or industrial property protection for any Jointly Developed Intellectual Property in any particular country or not to share equally in the expenses thereof with the other party, the other party shall have the right to seek or maintain such protection at its sole expense in such country and shall have full control over the prosecution and maintenance thereof even though title to any patent or other intellectual or industrial property protection issuing therefrom shall be jointly owned by the parties.

(2) To the extent OpNext Japan shares the costs of its proportion of the joint funding as described in (1) above, with either OpNext R&D-USA or any other Wholly-Owned Subsidiary of OpNext, Inc. for an R&D Project that is jointly funded by Hitachi and OpNext Japan, OpNext Japan shall have the right to license any Jointly Developed Intellectual Property arising from such R&D Project and the right to sublicense any Hitachi R&D IP associated with such Jointly Developed Intellectual Property, to OpNext R&D USA and such other Wholly-Owned Subsidiary of OpNext, Inc., as the case may be; provided, however, the following conditions are met: (i) OpNext Japan obtains Hitachi’s reasonable prior consent; and (ii) OpNext R&D-USA and such other Wholly-Owned Subsidiary of OpNext, Inc. abide by the terms and conditions of this R&D Agreement. Notwithstanding the foregoing, if any such license invokes any Japanese tax issues then Hitachi shall not be obliged to consent to such license to OpNext R&D-USA and/or such other Wholly-Owned Subsidiary of OpNext, Inc. without entering into a separate agreement with OpNext R&D-USA and/or such other Wholly-Owned Subsidiary of OpNext, Inc. under reasonable terms and conditions to be agreed upon between the relevant parties to address such tax issues. Notwithstanding the foregoing, neither OpNext R&D USA nor any such Wholly-Owned Subsidiary of OpNext, Inc. shall have any ownership rights in such Jointly Developed Intellectual Property.

(iii) OpNext Japan Owned.

(1) If OpNext Japan desires and Hitachi agrees in its reasonable discretion, OpNext Japan may purchase the Intellectual Property resulting from an R&D Project that is either owned by Hitachi under Section 4(c)(i) or jointly owned by the parties under Section 4(c)(ii), but excluding Hitachi R&D IP and Licensed IP, by reimbursing Hitachi for any New Development Costs incurred by Hitachi in such R&D Project and paying a ▇▇▇▇-Up to Hitachi in accordance with the formula set forth in Exhibit C hereto.

(2) If OpNext Japan desires and Hitachi agrees in its reasonable discretion, OpNext Japan may purchase the Intellectual Property resulting from an R&D Project that is either owned by Hitachi under Section 4(c)(i) or jointly owned by the parties under Section 4(c)(ii) including the Hitachi R&D IP and Licensed IP on which such Intellectual Property is based or derived, by paying a ▇▇▇▇-Up Fee. For the purposes of determining such ▇▇▇▇-Up Fee, the parties shall consider the extent of Hitachi’s New Development Costs, Hitachi’s Old Development Costs and the fair market value of such

- 13 -

technology (other than Assigned IP, Licensed IP and OpNext Japan R&D IP assigned pursuant to Section 2(c)(i)).

(d) Ownership Determination. Prior to the commencement of an R&D Project, the Hitachi and OpNext Japan Project Managers shall discuss in good faith the ownership of the Intellectual Property resulting from such R&D Project based upon the principles listed above. If the parties’ Project Managers cannot agree on the ownership of the Intellectual Property, the management of both parties shall discuss in good faith the ownership of the Intellectual Property resulting from such R&D Project. If the management is unable to come to an agreement on such ownership issues (including clear identification of the Intellectual Property resulting from such R&D Project, New Development Costs, Old Development Costs, OpNext Japan’s non-monetary contribution to the R&D Project and the ▇▇▇▇-Up Fee, if applicable), the parties shall refer this issue to arbitration pursuant to the arbitration procedures set forth in Exhibit E hereto. In the event that it is impractical to resolve the disputed issue prior to the commencement of the R&D Project (e.g., the parties are unsure as to what extent underlying technology will be utilized or cannot determine the identification of Intellectual Property resulting from the R&D Project, the New Development Costs, Old Development Costs, OpNext Japan’s non-monetary contribution to the R&D Project or ▇▇▇▇-Up Fee), either party may elect to proceed with the R&D Project and defer resolution of the disputed issue until a later date; provided that if the parties remain in disagreement after such later date, the parties shall then refer the issue to arbitration as described above. In the event that either party submits the dispute to arbitration, both parties shall cooperate in such binding arbitration in accordance with Exhibit E.

Section 5. Cross License of Intellectual Property.

(a) OpNext Japan R&D IP License. OpNext Japan will license, and does hereby license effective as of the First Closing Date, the OpNext Japan R&D IP to Hitachi and its Wholly-Owned Subsidiaries on a fully paid-up, non-exclusive, perpetual and irrevocable basis, to use, make, have made, sell, advertise, offer to sell, lease, import, export and supply products and services throughout the world, provided, however, that Hitachi and its Wholly-Owned Subsidiaries shall not have the right to sublicense OpNext Japan R&D IP to any entity without the consent of OpNext Japan.

(b) Hitachi R&D IP License. Hitachi will license, and does hereby license effective as of the First Closing Date, the Hitachi R&D IP relevant to the Business to OpNext Japan on a fully paid-up, non-exclusive, perpetual and irrevocable basis, to use, make, have made, sell, advertise, offer to sell, lease, import, export and supply products and services throughout the world (“Licensed Hitachi R&D IP”). Hitachi also will grant, and hereby does grant, to OpNext Japan the right to freely sublicense the Licensed Hitachi R&D IP to its Subsidiaries, to OpNext, Inc. and OpNext, Inc.’s Subsidiaries; provided, however, that OpNext Japan will not have the right to sublicense any Licensed Hitachi R&D IP that is developed or filed after the Second Closing Date to any entity other than OpNext, Inc. or OpNext Japan’s or OpNext, Inc.’s Wholly-Owned Subsidiary, without the consent of Hitachi.

(c) Transfer of Licensed IP. In the event a Subsidiary or division of Hitachi that is the owner of the Licensed IP or Hitachi R&D IP is sold or otherwise

- 14 -

transferred by Hitachi, Hitachi will make necessary arrangements to secure a license under the terms and conditions of the IP License Agreement for OpNext Japan from the new owner such that OpNext Japan can continue to use such Licensed IP and/or Hitachi R&D IP until such Licensed IP or Hitachi R&D IP, respectively, expires.

(d) Termination Conditions. Such a license of OpNext Japan R&D IP to Hitachi and of Licensed Hitachi R&D IP to OpNext Japan shall not be terminated or its exploitation enjoined, until and unless: (i) the licensee has committed a material breach of its obligations under this R&D Agreement, the licensor has given written notice of such breach to the licensee and such breach remains uncured during the Cure Period, or, in the case of a breach which cannot be cured within such Cure Period, the licensee has not instituted within such Cure Period steps necessary to remedy the default and/or thereafter has not diligently pursued the same to completion; or (ii) the breaching party has committed an incurable material breach. In the event the breach is a curable breach that cannot be cured within the Cure Period but the licensee 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 the 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 E 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 E 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 E.

(e) Review of Obligations. The obligations set forth in this Section 5 shall expire on the tenth (10^th) anniversary of the Second Closing Date of the Stock Purchase Agreement; provided, however, that the licenses under OpNext Japan R&D IP and Licensed Hitachi R&D IP existing as of the tenth (10^th) anniversary of the Second Closing Date shall continue, under reasonable terms and conditions to be agreed between the parties, until the expiration of all of such OpNext Japan R&D IP and Licensed Hitachi R&D IP. Notwithstanding the foregoing, if one (1) of the conditions set forth in Section 5(d) is met, the non-breaching party may elect to be completely relieved of its obligations set forth in this Section 5. If a party elects to be relieved of its obligations under this Section 5(d), the parties shall renegotiate in good faith and on commercially reasonable terms a new license governing the OpNext Japan R&D IP and/or Licensed Hitachi R&D IP, as applicable.

Section 6. Covenants to Protect Intellectual Property.

(a) Notice of Infringement. If either party learns of facts that may constitute an infringement of any of the Intellectual Property covered by this R&D Agreement or of any allegations that there has been an infringement of such Intellectual Property, it shall promptly notify the owner of the Intellectual Property of such possible infringement. With respect to Jointly Developed Intellectual Property, each party shall notify the other party of such possible infringement. No party shall have any duty to conduct any investigation or to make any inquiry with respect to any such alleged infringement.

- 15 -

(b) Infringement Suits on Jointly Developed Intellectual Property. If both parties agree to initiate appropriate action to cause any infringement of Jointly Developed Intellectual Property to cease, including if necessary bringing suit to enjoin such infringement, the parties shall share the expense and split any damages or other court compensation equally, or in some other proportion to be agreed by the parties prior to initiating an action. If upon notice of infringement of Jointly Developed Intellectual Property, a party elects not to initiate any action, the other party shall have the option to initiate appropriate action to cause any infringement to cease, including if necessary bringing suit to enjoin such infringement; and such party shall then be solely responsible for expenses and shall retain any damages and other court compensation awarded but such party shall not enter into a settlement agreement without the prior written consent of the other party, which shall not be unreasonably withheld, unreasonably delayed or unreasonably conditioned.

(c) Infringement of Licensed Hitachi R&D IP. To the extent a competitor of the Business is infringing the Licensed Hitachi R&D IP in OpNext Japan’s reasonable business judgment and such infringement is material to the Business, Hitachi will protect OpNext Japan’s interest either by prosecuting the Intellectual Property rights on behalf of OpNext Japan or by taking some other appropriate action that will not have a Material Adverse Effect on the ongoing business of OpNext Japan, provided, however, that any such action taken by Hitachi shall not materially adversely affect any other Affiliates of or business units of Hitachi. Both parties shall consult and cooperate with each other in determining how to respond to the infringing activities. 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 any such matter by granting a sublicense of all or portion of the Licensed Hitachi R&D IP.

Section 7. Inventor Compensation. Both parties acknowledge and agree that in the event that any employee of Hitachi or employee of OpNext Japan (hereinafter referred to as the “Inventor”) creates any Intellectual Property under this R&D Agreement, the owner of such Intellectual Property shall pay a certain amount of compensation to such Inventor, taking into account the Inventor’s contribution, and according to the terms and conditions mutually agreed to by the parties.

Section 8. Warranties and Limitations

(a) Existing R&D Agreements. Hitachi represents and warrants that the terms and conditions of the Existing R&D Agreements shall not have a material impact on OpNext Japan’s ability to conduct its research and development activities pursuant to this R&D Agreement or the ownership of or other rights in any Intellectual Property that may result from such activities, and that Hitachi will make Commercially Reasonable Efforts to consult and cooperate with OpNext Japan to eliminate or minimize any negative impact arising from the terms and conditions of any Existing R&D Agreements.

(b) Disclaimer of Warranties. Hitachi expressly disclaims all representations and warranties, express or implied, in connection with the R&D Support

- 16 -

provided pursuant to this R&D Agreement, including the warranties of non-infringement and title and the implied warranties of merchantability and fitness for a particular purpose. Such R&D Support is provided on an “as is” basis, except as set forth on Exhibit D.

(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, employees and agents (as applicable) and hold them harmless from any loss, liability, damage or expense (including court costs and reasonable attorneys’ fees) (the “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 R&D Agreement; or (ii) any breach of any covenant of Hitachi contained in this R&D Agreement; except to the extent that OpNext Japan, its Affiliates, their agents and/or their independent contractors have tortiously contributed in an intentional or grossly negligent manner to the event in question. Notwithstanding the foregoing, in no event shall Hitachi indemnify OpNext Japan under this indemnity provision for claims under Section 8(c)(i) brought on or after two (2) years after the Second Closing Date and in no event shall Hitachi’s obligations under this provision exceed an amount of four hundred and twenty-eight point six million dollars ($428.6 million).

(d) IP Infringement Indemnification. 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 OpNext Japan R&D IP resulting from the Current R&D Projects or Hitachi R&D IP. 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 on or after April 1, 2001: (i) 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 Current R&D Project; (ii) 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 arises from OpNext Japan R&D IP for which OpNext Japan has paid one hundred percent (100%) of the New Development Costs irrespective of whether such claim results from a Current R&D Project or a Future R&D Project; and (iii) both parties shall be jointly responsible for the settlement amount of any such claim (provided that prior written approval is obtained) for the resulting liability of any such claim to the extent it arises from Jointly Developed Intellectual Property in the same proportion as the parties agreed to allocate the New Development Costs prior to commencement of the R&D Project. To the extent there is a dispute regarding the allocation of the parties’ liabilities under this subsection, the parties shall negotiate in good faith 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 E hereto. In the event that either party submits the dispute to arbitration, both parties shall cooperate in such binding arbitration in accordance with Exhibit E. Notwithstanding the foregoing, in no event shall either party indemnify the other under this infringement and misappropriation indemnity provision for claims brought on or after two (2) years after the Second Closing Date of the Stock Purchase Agreement and in no event shall either party’s obligations under this provision exceed an amount of four hundred and twenty-eight point six million dollars

- 17 -

($428.6 million). The indemnification under this Section 8 shall be provided in accordance to the procedures set forth in Section 11 of the IP License Agreement.

(e) 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 by OpNext Japan contained in this R&D Agreement; or (ii) any breach of any covenant of OpNext Japan contained in this R&D Agreement; except to the extent that Hitachi, its Affiliates, their agents and/or their independent contractors have tortiously contributed in an intentional or grossly negligent manner to the event in question. Notwithstanding the foregoing, in no event shall OpNext Japan indemnify Hitachi under this indemnity provision for claims under Section 8(e)(i) brought on or after two (2) years after the Second Closing Date and in no event shall OpNext Japan’s obligations under this provision exceed an amount of four hundred and twenty-eight point six million dollars ($428.6 million).

(f) Limitation of Liability. Neither party shall be liable to the other party or any third party for any special, consequential, exemplary or incidental damages (including lost or anticipated revenues or profits relating to the same), arising from any claim relating to this R&D Agreement, whether such claim is based on warranty, contract, tort (including negligence or strict liability) or otherwise, even if an authorized representative of such party is advised of the possibility or likelihood of same.

Section 9. Expenses. OpNext Japan shall be charged for R&D Support on the same basis that Hitachi’s Wholly-Owned Subsidiaries are allocated research and development charges for their activities, provided that in no event shall such terms be less advantageous from OpNext Japan’s perspective, than those terms which could be reasonably expected to be obtained in an arms-length transaction. Notwithstanding the foregoing, OpNext Japan acknowledges and agrees that if it exercises its rights under Section 4(c)(iii), OpNext Japan shall pay a ▇▇▇▇-Up Fee to Hitachi. Whether or not the transactions contemplated hereby are consummated, and except as otherwise specifically provided in this R&D Agreement, all costs and expenses incurred in connection with this R&D Agreement and the transactions contemplated hereby shall be paid by the party incurring such costs or expenses.

Section 10. Termination. This R&D Agreement will automatically terminate and be of no further force or effect upon the termination of the Stock Purchase Agreement or upon the tenth (10^th) anniversary of the Second Closing Date; provided, however, that the following provisions of this R&D Agreement survive termination of this R&D Agreement: (i) Section 11 relating to the obligation of the parties to keep confidential certain information and data (ii) Section 5(e) to the extent that the Licensed Hitachi R&D IP and/or OpNext Japan R&D IP has not expired; (iii) Sections 8(a), 8(b), 8(c), 8(d), 8(e) and 8(f) relating to indemnification; and (iii) Section 9 relating to expenses, or any other term which specifically states that it survives termination of this R&D Agreement.

Section 11. Confidentiality.

(a) Confidentiality Obligations. Confidential Information will not be disclosed or made available by the receiving party, directly or indirectly, to any third party, except as shall be agreed to in writing by the disclosing party. Each of the parties agrees to take all reasonable steps to preserve the confidentiality of the other’s Confidential Information in accordance with their respective policies for the protection of their own non-public information (which policies shall provide at least reasonable protection) and agrees that it will be made available only to those employees as shall have a need to see and use for the purpose of fulfilling that party’s obligations under this R&D Agreement, and any such employee shall be informed of the confidential nature of the Confidential Information and shall be required to observe the confidentiality obligations in respect thereof. The receiving party shall ensure that all Confidential Information received by it is kept separate (together with all information generated by the receiving party therefrom) from all documents and other records of the receiving party, and that it shall not use, reproduce, transfer or store any of the Confidential Information in an extremely accessible place.

(b) Exclusions.

(i) The limitations set forth in this Section 11 shall not apply with respect to the disclosure of any information: (i) to the receiving party’s employees, auditors, counsel, other professional advisors, sublicensees authorized under the terms of this R&D Agreement (Sections 2(c) and 5(a) for OpNext Japan R&D IP and Section 5(b) for Hitachi R&D IP) or suppliers if the receiving party or any of its sublicensees authorized under the terms of this R&D Agreement (Sections 2(c) and 5(a) for OpNext Japan R&D IP and Section 5(b) for Hitachi R&D IP), in its sole discretion, determines that it is reasonably necessary for such Person to have access to such information, provided that any such Person agrees to be bound by the provisions of this Section 11(a) to the same extent as the receiving party; (ii) as has become or previously was generally available to the public other than by reason of a breach of this Section 11(a) by the receiving party or has become available to the receiving party 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 the receiving party (it being understood that, to the extent practicable, the receiving party shall provide the disclosing party prompt notice to any such event and cooperate in good faith to enable the disclosing party 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 the receiving party.

(ii) Notwithstanding Section 11(a)(i), to the extent that after the Second Closing Date, Hitachi desires to disclose to Hitachi Minority-Owned Affiliates and/or suppliers OpNext Japan R&D IP, 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 Minority-Owned Affiliate or supplier 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 the Hitachi Minority-Owned Affiliate or supplier; (ii) propose reasonably modified terms and conditions of the nondisclosure agreement under which

- 19 -

OpNext Japan will provide the requested confidential information to Hitachi’s Minority-Owned Affiliate or supplier; 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 E hereto. In the event that either party submits the dispute to arbitration, both parties shall cooperate in such binding arbitration in accordance with Exhibit E.

(c) Injunctive Relief. The parties acknowledge and agree that money damages would be inadequate to remedy any breach of the confidentiality obligations in this Section 11 and that the non-breaching party shall be entitled to obtain equitable remedies with respect to any such breach, including injunctive relief.

(d) Ownership. All Confidential Information furnished hereunder shall be and remain the exclusive property of the disclosing party, and the receiving party agrees to promptly return to the disclosing party, upon the disclosing party’s request, all documents, samples and other material in the possession, custody or control of the receiving party that bear or incorporate any part of the Confidential Information, including all copies made by the receiving party, except as otherwise provided herein.

(e) Press Releases and Announcements. 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 R&D 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 Commercial Reasonable Efforts to enable the other party to review and comment on all such news releases prior to the release thereof.

Section 12. Export Control. Each party shall comply and 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 5 above) is unable to obtain any required export license or other governmental approval, and as a result the licensor (under Sections 2 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 14. Amendment and Waiver. No amendment of any provision of this R&D 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 R&D 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 R&D Agreement in accordance with its terms.

Section 15. Assignment. Except as set forth below, this R&D 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 16. Counterparts. This R&D Agreement 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.

Section 17. Delivery by Facsimile. This R&D Agreement, the agreements referred to herein, and each other agreement or instrument entered into in connection herewith or contemplated hereby, and any amendments hereto or thereto, to the extent signed and delivered by means of a facsimile machine, shall be treated in all manner and respects as an original agreement or instrument and shall be considered to have the same binding legal effect as if it were the original signed version thereof delivered in person. At the request of any party hereto or to any such agreement or instrument, each other party hereto shall reexecute original forms thereof and deliver them to all other parties. No party hereto or to

- 22 -

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.

Section 18. Exhibits and Schedules. All Exhibits and Schedules annexed hereto or referred to herein are hereby incorporated in and made a part of this R&D Agreement as if set forth in full herein.

Section 19. Further Assurances. During the term of this R&D Agreement and at all times thereafter, each party shall provide to the other party, at its request, reasonable cooperation and assistance (including the execution and delivery of affidavits, declarations, oaths, assignments, samples, exhibits, specimens and any other documentation) as necessary to effect the terms of this R&D Agreement.

Section 20. Governing Law. Except for Section 8(a), this R&D 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 of Japan. Section 8(a) shall be governed by and construed in accordance with the laws of the U.S. and the State of New York without giving effect to any choice-of-law or conflict-of-law provision or rule (whether of the State of New York or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of New York. 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 21. Dispute Resolution. In the event of any dispute under this R&D Agreement, 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 R&D 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) 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 E.

Section 22. Interpretation. The headings and captions contained in this R&D Agreement, in any Exhibit or Schedule hereto and in the table of contents to this R&D Agreement are for reference purposes only and do not constitute a part of this R&D

- 23 -

Agreement. The use of the word “including” herein shall mean “including without limitation.”

Section 23. No Strict Construction. Notwithstanding the fact that this R&D Agreement has been drafted or prepared by one of the parties, OpNext Japan and Hitachi confirm that both they and their respective counsel have reviewed, negotiated and adopted this R&D Agreement as the joint agreement and understanding of the parties, and the language used in this R&D Agreement shall be deemed to be the language chosen by the parties hereto to express their mutual intent, and no rule of strict construction shall be applied against any Person.

Section 24. Recordation. This R&D Agreement effects a transfer and license of rights in certain Intellectual Property and may be recorded in appropriate recordal repositories to evidence such transfer and license of rights.

Section 25. Relationship of the Parties. The parties hereto are independent contractors. The rights, obligations and liabilities of the parties shall be several and not joint or collective and nothing contained in this R&D Agreement shall be construed as creating a partnership, joint venture, agency, employment, trust or other association of any kind, each party being individually and independently responsible as set forth in this R&D Agreement.

Section 26. 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 5o 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 Assets, the Business or Hitachi. In addition, matters reflected in the Schedules or Exhibits are not necessarily limited to matters required by this R&D 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. Prior to the Second Closing, Hitachi shall have the right to supplement, modify or update the Schedules or Exhibits hereto to reflect changes in the ordinary course of the Business prior to the Second Closing; provided, however, that any such supplements, modifications or updates shall be subject to the written consent of Clarity.

Section 27. Severability. Whenever possible, each provision of this R&D Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this R&D 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 R&D Agreement in such jurisdiction or affect the validity, legality or enforceability of any provision in any other jurisdiction, but this R&D Agreement shall be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or unenforceable provision had never been contained herein.

Section 28. Submission to Jurisdiction; Waivers. With respect to disputes not required to be submitted to arbitration hereunder (including actions for injunctive relief under Section

- 24 -

11, or for confirmation or enforcement of an arbitration) each party to this R&D Agreement (including any third-party beneficiaries to this R&D Agreement) hereby irrevocably and unconditionally:

(i) submits for itself and its property in any legal action or proceeding relating to this R&D Agreement, or for recognition and enforcement of any judgment in respect thereof, to the exclusive general jurisdiction of the courts of Japan situated in Tokyo, Japan;

(ii) consents that any such action or proceeding may be brought in such courts, and waives any objection that it may now or hereafter have to the venue of any such action or proceeding in any such court or that such action or proceeding was brought in an inconvenient court and agrees not to plead or claim the same;

(iii) agrees that service of process in any such action or proceeding may be effected by mailing a copy thereof by registered or certified mail (or any substantially similar form of mail), postage prepaid, to such party at its address set forth herein or at such other address of which the agent shall have been notified pursuant thereto, to the extent permitted by the laws of Japan; and

(iv) agrees that nothing contained herein shall affect the right to effect service of process in any other manner permitted by law or shall limit the right to ▇▇▇ in any other jurisdiction.

Section 29. Survival. To the extent the terms of this R&D Agreement provide for rights, interest, duties, claims, undertakings and obligations subsequent to the termination or expiration of this R&D Agreement other than a termination caused by the termination of the Stock Purchase Agreement, such terms of this R&D Agreement shall survive such termination or expiration, including but not limited to the terms of Sections 1, 4, 6, 8 (subject to the two year survival period from the Second Closing Date), 9, 11, 12, 18, 19, 20, 21, 22, 23, 26, 27, 28, 29, 30 and 31.

Section 30. Third-Party Beneficiaries. OpNext Japan and Hitachi acknowledge and agree that this R&D Agreement is intended not only for the benefit of themselves and their Subsidiaries and for purposes of Section 11(b)(ii) their Minority-Owned Affiliates but also for the benefit of the Clarity Parties, OpNext, Inc. and OpNext Inc.’s Subsidiaries and Minority-Owned Affiliates.

EXHIBIT C
CALCULATION OF ▇▇▇▇-UP FEE

The ▇▇▇▇-Up Fee for purposes of Section 4(c)(iii)(1) shall be calculated as set forth below.

1. For any applicable R&D Project, Hitachi shall determine the monthly average cost per personnel for each Hitachi research laboratory in accordance with Section 9 of this R&D Agreement (the “Average Man-Month Cost”).

2. The Average Man-Month Cost shall then be multiplied by the number of personnel devoting or billing to time to the R&D Project for one month (the “Monthly Cost”).

3. The Monthly Costs shall then be multiplied by the number of months (or the pro rata portion thereof) during which work was performed on the R&D Project (the “Total Project Cost”).

4. “▇▇▇▇-Up” shall mean the amount equal to at least twenty-percent (20%) of the Total Project Cost but less than or equal to forty percent (40%) of the Total Project Cost that OpNext Japan may pay to Hitachi in accordance with Section 4(c)(iii). The ▇▇▇▇-Up may be increased above 20% to the extent that both Hitachi and OpNext Japan discuss in good faith and agree that new Intellectual Property of significantly greater value than the ordinary level is anticipated to be created or invented at the outset of the R&D Project. The parties acknowledge that in most situations the ▇▇▇▇-Up Fee shall range between 20%-40%, provided, however, that the ▇▇▇▇-Up may be increased above 40% to the extent that both parties discuss in good faith and agree to the extent of Hitachi’s contribution to the R&D Project and/or the result of the R&D Project is greater than expected. To the extent the ▇▇▇▇-Up is more than 40%, the total ▇▇▇▇-Up shall not exceed 60% of the portion of the Total Project Cost paid or incurred by OpNext Japan for such R&D Project.

5. ▇▇▇▇-Up Fee = Hitachi’s New Development Costs incurred in the R&D Project + ▇▇▇▇-Up (20%-40% x Total Project Cost) or (40% and above x Total Project Cost not to exceed 60% of the portion of the Total Project Cost paid or incurred by OpNext Japan for such R&D Project).

EXHIBIT D
R & D PROCEDURES

Hitachi and OpNext Japan will comply with the following procedures and requirements in connection with all R&D Project(s):

R & D Plan

1. Hitachi and OpNext Japan will each designate a project manager for all R&D Projects with supervisory responsibility for all R&D Projects (a “Project Manager”) within thirty (30) days after the Second Closing Date. Such Project Managers shall meet and prepare an initial R&D Plan within sixty (60) days after the Second Closing Date, covering all Current R&D Projects and all Future R&D Projects then planned by OpNext Japan. Both Project Managers will cooperate fully in the preparation of such R&D Plan and shall not unreasonably withhold, unreasonably delay or unreasonably condition approval of such R&D Plan.

2. The R&D Plan shall be updated and amended by the Hitachi Project Manager at least quarterly subject to the OpNext Japan Project Manager’s written approval, which will not be unreasonably withheld, unreasonably delayed or unreasonably conditioned.

3. The Project Managers (together with such other personnel as they deem appropriate) shall meet on a quarterly basis to prepare an updated and amended R&D Plan covering the next three (3) months. Each will cooperate fully in such preparation and shall not unreasonably withhold, unreasonably delay or unreasonably condition approval of such R&D Plan. In addition, Project Managers shall report the updated-status of each R&D Project in accordance with the milestones agreed upon at the beginning of such R&D Project.

4. Each R&D Plan shall cover all matters reasonably requested by the Project Managers, including the following:

4.1 A timetable for the R&D Support to be provided for each R&D Project, including minor and major milestones.

4.2 A list of deliverables and specifications for each R&D Project.

4.3 A budget and payment schedule in Japanese Yen for each R&D Project.

4.4 Assignment of Hitachi personnel and other resources to each R&D Project.

4.5 Test procedures for evaluation of deliverables.

4.6 Acceptance criteria for deliverables and for final acceptance of work product for each R&D Project, including suitability for efficient and cost-effective manufacturing.

4.7 Reporting procedures for notifying OpNext Japan of any problems or delays encountered by Hitachi that might affect the budget or the timetable for each R&D Project.

4.8 Ownership of Intellectual Property developed during an R&D Project or incorporated into the deliverables from an R&D Project.

OpNext Japan’s Obligations

1. OpNext Japan shall use Commercially Reasonable Efforts to ensure that its Project Manager complies with all of the requirements of this Exhibit D.

2. At least thirty (30) days prior to the date(s) by which Hitachi is required to prepare or amend the R&D Plan, OpNext Japan will submit to Hitachi work orders for each new R&D Project it desires to have included in such R&D Plan, specifying in commercially reasonable detail the specifications and other requirements for such R&D Project.

3. OpNext Japan shall make all payments required for R&D Projects in Japanese Yen.

Hitachi’s Obligations

1. Hitachi shall provide R&D Support in accordance with this Exhibit D and the R&D Agreement to which it is attached.

2. Hitachi shall at all times during the term of the R&D Agreement maintain the personnel, facilities and resources necessary to carry out the R&D Projects reasonably requested by OpNext Japan.

3. Prior to commencing any R&D Project, Hitachi shall inform OpNext Japan in writing if Hitachi anticipates that any Hitachi R&D IP or any Intellectual Property of any other person may, will or should be incorporated into any of the deliverables for such R&D Project, including any license terms applicable to such Hitachi R&D IP or other Intellectual Property. Similarly, Hitachi shall so inform OpNext Japan at any time during an R&D Project that Hitachi determines that any Hitachi R&D IP or any such Intellectual Property may, will or should be incorporated into any such deliverable. The parties shall negotiate in good faith and on reasonable terms to agree on whether or not such Hitachi R&D IP or other Intellectual Property will be incorporated into any of the deliverables and on the applicable license terms.

4. Hitachi shall make available all the necessary personnel, facilities and resources to comply with the project timetable for each R&D Project. Hitachi shall use Commercially Reasonable Efforts to complete each R&D Project in accordance with the project timetable and shall take steps to minimize any delays, including providing additional resources if necessary to ensure timeliness; provided, however, if the Hitachi does not comply with the project timetable, OpNext Japan may terminate the R&D Project. If Hitachi has taken Commercially Reasonable Efforts to complete such R&D Project and has taken

reasonable steps to minimize any delays, and for reasons beyond Hitachi’s (not in its capacity as a shareholder of OpNext, Inc.) control such R&D Project has been delayed, OpNext Japan shall pay all reasonable expenses incurred by Hitachi up until the time of the termination of such R&D Project. Hitachi shall be responsible for compliance with all applicable laws relating to such personnel, facilities and resources and for any claims or liabilities relating so thereto, including personal injury, property damage and/or product liability.

5. Within sixty (60) days after the Second Closing Date, Hitachi shall propose invention disclosure, record keeping procedures and processing guidelines covering the procedures for obtaining invention disclosures and identification of other Intellectual Property discovered or developed during each R&D Project under this R&D Agreement, documentation requirements and a timetable for applying for or registering patent applications, copyright registration and other forms of Intellectual Property protection (“IP Procedures”), subject to OpNext Japan’s written approval, which shall not be unreasonably withheld, unreasonably delayed or unreasonably conditioned. Hitachi shall also make available records and documentation to support the ownership of the Intellectual Property resulting from each R&D project under this R&D Agreement during the term of the R&D Agreement and for the respective terms of the patents provided, however, if both parties reasonably agree to abandon any such Intellectual Property, Hitachi shall not be obligated to maintain any records for such abandoned Intellectual Property. Hitachi shall maintain creation and discovery documentation of any Intellectual Property resulting from an R&D Project under this R&D Agreement in accordance with Hitachi’s standard business practice during the term of the R&D Agreement. At OpNext Japan’s request, Hitachi shall provide access to and copies of any such documentation that pertains solely to the Jointly Developed Intellectual Property that is jointly-owned under Section 4(c)(ii) of this R&D Agreement, to OpNext Japan and Hitachi shall maintain such documentation for a one-month period after OpNext Japan has been notified of a patent application filing. OpNext Japan shall also have the right to request copies of creation and discovery documentation for Hitachi R&D IP resulting from an R&D Project under Section 4(c)(i) of this R&D Agreement provided that: (i) such request is made within one month from the time OpNext Japan is notified by Hitachi of a patent application filing; (ii) such documentation is material to OpNext Japan’s business; and (iii) Hitachi approves to provide the copies of such documentation to OpNext Japan, such approval not to be unreasonably withheld, unreasonably delayed or unreasonably conditioned. Notwithstanding the above, Hitachi shall maintain the creation and discovery documentation for Hitachi R&D IP resulting from an R&D Project under Section 4(c)(i) of this R&D Agreement until it has determined whether such documentation shall be provided to OpNext Japan.

6. Prior to commencing and during each R&D Project, Hitachi shall notify OpNext Japan in writing to the extent Hitachi believes that any Hitachi R&D IP or Intellectual Property of any other person could be utilized in connection with such R&D Project and which might or would reduce the cost or timetable for such R&D Project. The parties shall negotiate in good faith and on reasonable terms to agree on whether or not to include such Hitachi R&D IP or other Intellectual Property in the R&D Project and on the applicable license terms.

7. Hitachi shall provide to OpNext Japan reasonable training, documentation and manuals in connection with each R&D Project, except materials subject to the restriction under Third Party License Agreements.

8. Hitachi represents, warrants and covenants that the R&D Support provided by Hitachi and the deliverables and other work product from each R&D Project and the use, manufacturing, sale, license, lease or other distribution of thereof by OpNext Japan will comply with all applicable laws and regulations.

9. Hitachi shall obtain assignments from all employees or other personnel working on any of the R&D Projects that are sufficient under all applicable laws to grant to Hitachi ownership of all Intellectual Property developed during each R&D Project that Hitachi has agreed to assign to OpNext Japan.

10. During the term of the R&D Agreement Hitachi will provide reasonable post-acceptance support to OpNext Japan with respect to the deliverables and products resulting from each R&D Project.

Section 7. Amendments to Section 8.

Section 8 of the R&D Agreement is hereby amended by adding after clause (f) the following clauses:

(g) Indemnification by Hitachi. From and after October 1, 2002, Hitachi shall indemnify Opto-Device and its Affiliates and each of their respective officers, directors, members, stockholders, partners, employees and agents (as applicable) 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 Hitachi contained in this R&D Agreement; or (ii) any breach of any covenant of Hitachi contained in this R&D Agreement; except to the extent that Opto-Device, its Affiliates, their agents and/or their independent contractors have tortiously contributed in an intentional or grossly negligent manner to the event in question. Notwithstanding the foregoing, in no event shall Hitachi indemnify Opto-Device under this indemnity provision for claims under Section 8(g)(i) brought on or after one (1) year after October 1, 2002 and in no event shall Hitachi’s obligations under this provision exceed an amount of one billion (1,000,000,000) Yen.

(h) IP Infringement Indemnification. 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 October 1, 2002, Hitachi and Opto-Device shall jointly defend such action but only to the extent that such

claim involves OpNext Japan R&D IP resulting from (a) the Current R&D Projects related to the HTS Business or the SIC Business or (b) Hitachi R&D IP. If a third party patent or copyright infringement claim or trade secret misappropriation claim is made against Opto-Device for a new product design that is developed on or after October 1, 2002: (i) 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 Current R&D Project related to the HTS Business or the SIC Business; (ii) Opto-Device 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 arises from OpNext Japan R&D IP relating to the HTS Business or the SIC Business for which Opto-Device has paid one hundred percent (100%) of the New Development Costs irrespective of whether such claim results from a Current R&D Project or a Future R&D Project; and (iii) Opto-Device and Hitachi shall be jointly responsible for the settlement amount of any such claim (provided that prior written approval is obtained) for the resulting liability of any such claim to the extent it arises from Jointly Developed Intellectual Property in the same proportion as the parties agreed to allocate the New Development Costs prior to commencement of the R&D Project. To the extent there is a dispute regarding the allocation of the parties’ liabilities under this subsection, the parties shall negotiate in good faith 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 E hereto. In the event that either party submits the dispute to arbitration, both parties shall cooperate in such binding arbitration in accordance with Exhibit E. Notwithstanding the foregoing, in no event shall either party indemnify the other under this infringement and misappropriation indemnity provision for claims brought on or after one (1) year after October 1, 2002 and in no event shall either party’s obligations under this provision exceed an amount of one billion (1,000,000,000) Yen. The indemnification under this Section 8 shall be provided in accordance to the procedures set forth in Section 11 of the Opto-Device IP License Agreement.

(i) Indemnification by Opto-Device. From and after October 1, 2002, Opto-Device 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: (1) any breach of any representation or warranty by Opto-Device contained in this R&D Agreement; or (2) any breach of any covenant of Opto-Device contained in this R&D Agreement; except to the extent that Hitachi, its Affiliates, their agents and/or their independent contractors have tortiously contributed in an intentional or grossly negligent manner to the event in question. Notwithstanding the foregoing,

in no event shall Opto-Device indemnify Hitachi under this indemnity provision for claims under Section 8(i)(l) brought on or after one (1) year after October 1, 2002 and in no event shall Opto-Device’s obligations under this provision exceed an amount of one billion (1,000,000,000) Yen.

(j) Limitations on Indemnification.

For the avoidance of doubt:

(1) an indemnifying party’s liability under Sections 8(c)(i), 8(d) and 8(e)(i) of this R&D Agreement, Sections 11(b), 11(c)(i) and 11(d)(i) and (iii) of the 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 OpNext Japan 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); and

(2) an indemnifying party’s liability under Sections 11(b), 11(c)(i) and 11(d)(i) and (iii) of the Opto-Device IP License Agreement or Sections 17(a)(i) and 17(a)(iv), 17(b), 17(c) and 17(d)(i) and 17(d)(vi) (as Sections 17(a) and 17(d) relate to Assigned IP, Licensed IP or any other Intellectual Property relevant to the SIC Business and HTS Business) of the Stock Purchase Agreement or Sections 8(g)(i), 8(h) and 8(i)(1) of this R&D Agreement in the aggregate shall in no event exceed one billion Yen (¥ 1,000,000,000).

Section 13. 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 14. 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).

Section 17. 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.

SECOND AMENDMENT TO OPNEXT JAPAN R&D AGREEMENT

THIS SECOND AMENDMENT TO OPNEXT JAPAN R&D AGREEMENT (this “Amendment”) is entered into as of October 27, 2006 (the “Amendment Date”), by and between Hitachi, Ltd., a corporation existing under the laws of Japan (“Hitachi”) and Opnext Japan, Inc., a corporation existing under the laws of Japan (“Opnext Japan”) and a Wholly-Owned Subsidiary of Opnext, Inc., a Delaware corporation (“Opnext, Inc.”), and successor by merger to Opto-Device, Ltd., a corporation formerly existing under the laws of Japan (“Opto-Device”). All capitalized terms used herein but not defined herein shall have the meaning ascribed to such terms in the R&D Agreement (as defined below).

RECITALS

WHEREAS, Hitachi and Opnext Japan have entered into that certain Research and Development Agreement dated as of July 31, 2001 (the “Original R&D Agreement”), as amended by the First Amendment thereto dated as of October 1, 2002 (the “First Amendment” and together with the any other amendments to the Original R&D Agreement, the “R&D Agreement”); and

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

Section 1. Amendment Date.

This Amendment shall be effective as of the Amendment Date. This Amendment and any amendments made to the provisions of the R&D Agreement hereunder shall have no retroactive effect.

Section 2. Amendment.

(1) Section 1(o) of the R&D Agreement is hereby amended by deleting it in its entirety and replacing it with the following:

“Jointly Developed Intellectual Property” shall mean all Intellectual Property resulting from an R&D Project under this R&D Agreement in accordance with Section 4(c)(ii) hereof, and shall exclude Hitachi R&D IP, Licensed IP and Assigned IP and Opnext Japan R&D IP.

(2) Section 2(c)(ii) of the R&D Agreement is hereby amended by deleting it in its entirety and replacing it with the following Section 2(c)(ii):

(ii) Termination Conditions. Such license shall not be terminated or its exploitation enjoined, until and unless: (i) Opnext Japan has committed

a material breach of its obligations under this R&D Agreement, Hitachi has given written notice of such breach to Opnext Japan and such breach remains uncured after sixty (60) days of receiving notice of such breach (the “Cure Period”), or, in the case of a breach that cannot be cured within such Cure Period, Opnext Japan has not instituted within such Cure Period steps necessary to remedy the default and/or thereafter has not diligently pursued the same to completion; or (ii) Opnext Japan has committed an incurable material breach. 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 E 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 E 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. In the event that either party submits the dispute to arbitration, both parties shall cooperate in such binding arbitration in accordance with Exhibit E.

(3) Section 2(c)(iii) of the R&D Agreement is hereby amended by deleting it in its entirety and replacing it with the following Section 2(c)(iii):

(iii) License Term. The license to the Intellectual Property licensed pursuant to Section 2(c)(i) shall be irrevocable and: (i) with respect to patent rights, shall survive for so long as any applicable patent is valid; and (ii) with respect to all other Intellectual Property, shall be perpetual.

(4) The last sentence of Section 4(a) of the R&D Agreement is hereby amended by deleting it in its entirety and replacing it with the following sentence:

Hitachi shall cooperate with Opnext Japan in a reasonable manner in obtaining such protection, including, obtaining signatures of Hitachi employees, contractors and/or officials on official papers.

(5) The last sentence of Section 4(b) of the R&D Agreement is hereby amended by deleting it in its entirety and replacing it with the following sentence:

Hitachi shall have the right to apply, in its own name and at its own expense, for Intellectual Property protection in Hitachi R&D IP and, if requested, Opnext Japan shall cooperate with Hitachi in any reasonable manner in obtaining such protection, including, obtaining signatures of Opnext Japan employees, contractors and/or officials on official papers.

(6) Section 4(c)(ii)(1) of the R&D Agreement is hereby amended by deleting it in its entirety and replacing it with the following Section 4(c)(ii)(1):

(1) If the R&D Project is jointly funded by the parties and either: (A) Opnext Japan contributes fifty percent (50%) or more of the New Development Costs to the R&D Project; or (B) Opnext Japan contributes less than fifty percent (50%) of the New Development Costs to the R&D Project but (i) one or more employees or contractors (other than employees of Hitachi or its Subsidiaries) of Opnext Japan are “inventors” under the applicable patent laws of the applicable jurisdiction or (ii) the parties determine through good faith negotiations that Opnext Japan contributed to the R&D Project in some other fashion, and in both (A) and (B) above the resulting Intellectual Property can clearly be identified with reasonable certainty as that resulting from such R&D Project, then such Intellectual Property shall be deemed Jointly Developed Intellectual Property and shall be owned jointly by the parties and either party may practice such Jointly Developed Intellectual Property without an accounting or compensation to, or the consent of, the other party. Except as set forth in Section 4(c)(iii) below, if either party desires to license any of its rights to the Jointly Developed Intellectual Property herein to a third party, it shall obtain the prior written consent of the other party hereto. Each party shall have the right to apply, in both parties’ names, for Intellectual Property protection in the Jointly Developed Intellectual Property. The parties shall agree on the proper way and strategy for proceeding with all protection of the Jointly Developed Intellectual Property in accordance with the R&D Procedures. All expenses incurred in obtaining and maintaining Intellectual Property protection in the Jointly Developed Intellectual Property shall be equally shared by the parties. In the event that one (1) of the parties elects not to seek or maintain patent or other intellectual or industrial property protection for any Jointly Developed Intellectual Property in any particular country or not to share equally in the expenses thereof with the other party, the other party shall have the right to seek or maintain such protection at its sole expense in such country and shall have full control over the prosecution and maintenance thereof even though title to any patent or other intellectual or industrial property protection issuing therefrom shall be jointly owned by the parties.

(7) Section 5(d) of the R&D Agreement is hereby amended by deleting it in its entirety and replacing it with the following Section 5(d):

(d) Termination Conditions. Such a license of Opnext Japan R&D IP to Hitachi and of Licensed Hitachi R&D IP to Opnext Japan shall not be terminated or its exploitation enjoined, until and unless: (i) the licensee has committed a material breach of its obligations under this R&D Agreement, the licensor has given written notice of such breach to the licensee and such breach remains uncured during the Cure Period, or, in the case of a breach which cannot be cured within such Cure Period, the licensee has not instituted within such Cure Period steps necessary to remedy the default and/or thereafter has not diligently pursued the same to completion; or (ii) the breaching party has committed an incurable material breach. In the event the breach is a curable breach that cannot be cured within the Cure Period but the licensee 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 the 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 E 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 E hereto to determine the appropriate remedy, and (ii) the breaching party shall provide an on-going plan to address the prevention of such a breach occurring again reasonably acceptable to non-breaching party 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. In the event that either party submits the dispute to arbitration, both parties shall cooperate in such binding arbitration in accordance with Exhibit E.

(8) Section 5(e) of the R&D Agreement is hereby amended by deleting it in its entirety and replacing it with the following Section 5(e):

(e) License Term and Review of Obligations.

(i) License Term. The license to the Opnext Japan R&D IP to Hitachi and Licensed Hitachi Future R&D IP (as defined below) to Opnext Japan shall be irrevocable and: (i) with respect to patent rights, shall survive for so long as any applicable patent is valid; and (ii) with respect to all other Opnext Japan R&D IP and Licensed Hitachi Future R&D IP, shall be perpetual. For purposes of this Section, the term “Licensed Hitachi Future R&D IP” means Licensed Hitachi R&D IP resulting from a Future R&D Project. Notwithstanding the foregoing, (A) if one (1) of the conditions set forth in Section 5(d) is met, (x) Hitachi may terminate the licenses to Licensed Hitachi R&D IP that is developed or filed on or after the effective date of termination and (y) the licenses granted Opnext Japan to Licensed Hitachi Future R&D IP developed or filed prior to the effective date of termination shall continue pursuant to

the terms and conditions set forth herein and (B) if one (1) of the conditions set forth in Section 5(d) is met, (x) Opnext Japan may terminate the licenses to Opnext Japan R&D IP that is developed or filed on or after the effective date of termination and (y) the licenses granted Hitachi to Opnext Japan R&D IP developed or filed prior to the effective date of termination shall continue pursuant to the terms and conditions set forth herein.

(ii) Review of Obligations. The obligations set forth in this Section 5 with respect to Licensed Hitachi Other R&D IP (as defined below) shall expire on the tenth (10th) anniversary of the Second Closing Date of the Stock Contribution Agreement; provided, however, that the licenses under Licensed Hitachi Other R&D IP existing as of the tenth (10th) anniversary of the Second Closing Date shall continue, under reasonable terms and conditions to be agreed between the parties, until the expiration of all of such Licensed Hitachi Other R&D IP. Notwithstanding the foregoing, if one (1) of the conditions set forth in Section 5(d) is met, Hitachi may elect to be completely relieved of its obligations set forth in this Section 5 with respect to Licensed Hitachi Other R&D IP. If Hitachi elects to be relieved of its obligations under this Section 5(d), the parties shall renegotiate in good faith and on commercially reasonable terms a new license governing the Licensed Hitachi Other R&D IP. For purposes of this Section, the term “Licensed Hitachi Other R&D IP” means any Licensed Hitachi R&D IP other than Licensed Hitachi Future R&D IP. For the avoidance of doubt, the expiration or termination of Opnext Japan’s rights under this R&D Agreement with respect to Licensed Hitachi Other R&D IP will in no way affect Opnext Japan’s rights with respect to such Licensed Hitachi Other R&D IP, if any, under any other agreement to which Opnext Japan is a party.

(9) Section 10 of the R&D Agreement is hereby amended by deleting it in its entirety and replacing it with the following:

This R&D Agreement will automatically terminate and be of no further force or effect upon the fifth anniversary of an Initial Public Offering (as defined in the Stockholders’ Agreement); provided, however, that the provisions of this R&D Agreement identified in Section 29 shall survive expiration or termination of this R&D Agreement.

(10) Section 11(a) of the R&D Agreement is hereby amended by deleting it in its entirety and replacing it with the following Section 11(a):

The receiving party shall ensure that all Confidential Information received by it is kept separate (together with all information generated by the receiving party therefrom) from all documents and other records of the receiving party, and that it shall not use, reproduce, transfer or store any of the Confidential Information in an extremely accessible place.

(11) Section 15 of the R&D Agreement is hereby amended by adding the following clause at the end:

provided, however, that this R&D 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 of Hitachi.

(12) Section 29 of the R&D Agreement is hereby amended by deleting it in its entirety and replacing it with the following:

Section 29. Survival. To the extent the terms of this R&D Agreement provide for rights, interest, duties, claims, undertakings and obligations subsequent to the termination or expiration of this R&D Agreement other than a termination caused by the termination of the Stock Purchase Agreement, such terms of this R&D Agreement shall survive such termination or expiration, including but not limited to the terms of Sections 1, 4, 5 (with respect to licenses to Intellectual Property (other than Licensed Hitachi Other R&D IP) granted hereunder prior to the effective date of such termination), 6, 8 (subject to the two year survival period from the Second Closing Date), 9, 11, 12, 18, 19, 20, 21, 22, 23, 26-34.

(13) A new Section 33 is hereby added to the R&D Agreement which provides as follows:

Section 33. 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 R&D Agreement under Section 365 of the Bankruptcy Code, any and all rights licensed pursuant to this R&D 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 R&D 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 R&D 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 33.

(14) A new Section 34 is hereby added to the R&D Agreement which provides as follows:

Section 34. 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 R&D 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 R&D 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 R&D Agreement (including any unauthorized use or disclosure of that party’s Intellectual Property or Confidential Information).

Section 3. No Other Amendments.

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 R&D 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 34 of the R&D 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 E to the R&D Agreement.

Section 6. Interpretation.

Section 7. Severability.
