5

Opto-Device due to Hitachi’s reasonable requirements to use such Intellectual Property in other Hitachi business units; and (ii) all know-how and other Intellectual Property used in connection with the Business in whatever form that was not capable of assignment pursuant to the provisions of the Business Transfer Agreement due to Hitachi’s reasonable requirements to use such Intellectual Property in other Hitachi business units (e.g., product specifications, manufacturing processes, quality control procedures, instruction and/or operating, maintenance and safety materials and drawings, test procedures, test data, sources of material and supplies and the like). Hitachi shall use Commercially Reasonable Efforts to list all material patents that constitute Licensed IP on Exhibit A hereto, which schedule may be amended by the parties’ mutual written consent, together with an explanation of why each patent cannot be transferred to Opto-Device pursuant to the Business Transfer Agreement. For nine (9) months following the Closing, Hitachi and Opto-Device agree to cooperate in supplementing Exhibit B to the Stock Purchase Agreement to include all products sold by the Business and/or planned as of the Closing Date, all products planned during the one (1) year period prior to the Closing Date that pertain to the following research areas: (i) Tunable Lasers; (ii) 40G; (iii) Packaging Technology; and (iv) Modulators, and all products sold by the Business during the one (1) year period prior to the Closing Date; provided, however, to the extent any products are added to Exhibit B of the Stock Purchase Agreement that were not sold or planned as of the Closing Date (“Added Products”), at that time the parties will negotiate in good faith and on reasonable terms the extent to which the representations, warranties and covenants, or any other obligations of Hitachi under this IP License Agreement, the Stock Purchase Agreement and the OpNext Japan R&D Agreement would apply to such Added Products. For two (2) years following the Closing, Hitachi and Opto-Device agree to cooperate in supplementing Exhibit A hereof to include all material patents that are necessary or reasonably required for the purpose of operation of the Business as conducted on the Closing Date.

          (b) License.

               (i) Hitachi shall license, and does hereby license effective as of the Closing Date, the Licensed IP to Opto-Device, 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 using the Licensed IP, unless otherwise terminated according to the provisions in this IP License Agreement.

               (ii) Termination Conditions. Such license shall not be terminated or its exploitation enjoined, until and unless: (i) Opto-Device has committed a material breach of its obligations under this IP License Agreement, Hitachi has given written notice of such breach to Opto-Device 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, Opto-Device 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) Opto-Device 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 Opto-Device 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, 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. 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) Sublicense.

               (i) Subsidiaries. Hitachi will grant, and does hereby grant effective as of the Closing Date, to Opto-Device the right to freely sublicense the Licensed IP to its Subsidiaries, OpNext and OpNext’s Subsidiaries; provided, however, that Opto-Device will not have the right to sublicense any Licensed IP that is developed or filed for after the Closing Date, to any entity other than OpNext and Opto-Device’s and OpNext’s Wholly-Owned Subsidiaries, without the prior written consent of Hitachi, not to be unreasonably withheld, unreasonably delayed or unreasonably conditioned.

               (ii) Minority-Owned Affiliates. Opto-Device shall be permitted to further sublicense the Licensed IP to its Minority-Owned Affiliates, subject to approval by Hitachi, not to be unreasonably withheld, unreasonably delayed or unreasonably conditioned, and to commercially reasonable restrictions to be imposed by Hitachi that will be agreed to by the parties in writing.

               (iii) Customers. Opto-Device shall be permitted to further sublicense the Licensed IP to its customers as necessary or appropriate in connection with the completion of Opto-Device’s products and services, to complete the sale of products or services in the ordinary course of business or to enable joint development of a product or system with Opto-Device’s customers to be manufactured and sold by Opto-Device to such customers, provided Opto-Device proposes the terms and conditions of such sublicense to Hitachi and agrees that such sublicense shall be subject to Hitachi’s exercise of one (1) of the following options in Hitachi’s sole discretion, with respect to the terms and conditions proposed by Opto-Device: (i) Hitachi may consent to the sublicense terms and conditions as is; (ii) Hitachi may propose that a revised version of the sublicense, with reasonably modified terms and conditions be utilized; (iii) Hitachi may enter into a direct license with Opto-Device’s customer under the same terms and conditions as Opto-Device’s proposed sublicense; (iv) Hitachi may propose to enter into a direct license with Opto-Device’s customer under reasonably modified terms and conditions; or (v) Hitachi may commence discussions with Opto-Device to reach a resolution of Hitachi’s concerns with respect to such sublicense, if Hitachi believes such sublicense is not in the best interest of the parties. Hitachi shall have the sole discretion to determine which of the five (5) foregoing options Hitachi will exercise in each case. With respect to Hitachi’s exercise of one (1) of the five (5) foregoing options, Hitachi agrees to provide consents to and/or notify Opto-Device of Hitachi’s proposed modifications within fifteen (15) Business Days of receipt of the sublicense terms and conditions from Opto-Device. 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 Opto-Device;

provided, however, Hitachi shall not contact such Opto-Device customers that are the subject of negotiations between Hitachi and Opto-Device, without the prior written consent of Opto-Device 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.

          (d) Review of Obligations. The obligations set forth in this Section 3 shall expire on the tenth (10^th) anniversary of the Closing Date; provided, however, that the license under Licensed IP existing as of the tenth (10^th) anniversary of the Closing Date shall continue, under reasonable terms and conditions to be agreed between the parties, until the expiration of all of such Licensed IP. Notwithstanding the foregoing, if one (1) of the conditions set forth in Section 3(b)(ii) is met, Hitachi may elect to be completely relieved of its obligations set forth in this Section 3. If Hitachi elects to be relieved of its obligations under this Section 3, the parties shall renegotiate in good faith and on commercially reasonable terms a new license governing the Licensed 1P.

          (e) Obligation to Maintain Intellectual Property. Hitachi shall continue to maintain in effect all Intellectual Property relating to the Business through the Closing Date in the same manner as Hitachi has done prior to entering into the Stock Purchase Agreement. After the Closing Date, the Licensed IP shall be maintained by the division of Hitachi in control of such Licensed IP in a manner that is equal to the efforts, quality and resources devoted by such division as applicable in the ordinary course of the business from time to time for similar Intellectual Property.

          (f) Future Hitachi IP. “Future Hitachi IP” shall mean patents that may be issued to Hitachi and patent applications (including all extensions, reexaminations, reissues, continuations and renewals related thereto) that may be filed by Hitachi after the Closing Date but prior to the tenth (10^th) anniversary of the Closing Date that are reasonably relevant to the Business as conducted on the Closing Date and as modified or expanded in the future to the extent that any such modification or expansion relates to modifications to, extensions of or new versions of product lines existing or planned as of the Closing Date. The parties agree to cooperate and consult with each other to develop procedures by which Opto-Device will keep Hitachi informed of any modifications or expansions to the Business in order for Hitachi to identify Future Hitachi IP and notify Opto-Device accordingly. If requested by Opto-Device, any of such Future Hitachi IP will be licensed to Opto-Device under the terms and conditions set forth in Section 3(b)(i). Any such license pursuant to this Section 3(f) shall be subject to the termination provisions in Section 3(b)(ii), the sublicensing terms in Section 3(c), the renegotiation terms in Section 3(d) and the maintenance terms in Section 3(e). Notwithstanding Section 3(c), Opto-Device will have the right to freely sublicense Future Hitachi IP to its Subsidiaries, OpNext and OpNext’s Subsidiaries even if such Future Hitachi IP is developed or filed after the Closing Date. In the event that the parties disagree as to whether any particular Intellectual Property developed by Hitachi after the Closing constitutes Future Hitachi IP, the parties shall first attempt to resolve the dispute through good faith and reasonable negotiations in accordance with Section 12 hereof. In the event that the dispute cannot be resolved through such negotiations, a party shall refer the dispute to arbitration pursuant to the arbitration procedures

8

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.

          (g) Transfer of Licensed IP. In the event a division of Hitachi that is the owner of the Licensed IP or any Future Hitachi IP that is licensed to Opto-Device under Section 3(f) is sold or otherwise transferred by Hitachi, Hitachi will make necessary arrangements to secure a license under the terms and conditions of this IP License Agreement for Opto-Device from the new owner such that Opto-Device can continue to use such Licensed IP and such Future Hitachi IP until such Licensed IP and/or Future Hitachi IP expires hereunder, unless otherwise terminated according to the provisions of this IP License Agreement.

          (h) Change in Status.

          If at any time a Subsidiary, Wholly-Owned Subsidiary or Minority-Owned Affiliate of Opto-Device or a Subsidiary or Wholly-Owned Subsidiary of OpNext ceases to remain a Subsidiary, Wholly-Owned Subsidiary or Minority-Owned Affiliate (as appropriate) to the extent any sublicenses have been granted by Opto-Device or OpNext 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.

Section 4. Opto-Device Intellectual Property.

          (a) Definition. “Opto-Device IP” shall mean patents issued and patent applications filed after the Closing Date (including all extensions, reexaminations, reissues, continuations and renewals related thereto) of Opto-Device but filed prior to the tenth (10^th) anniversary of the Closing Date covering products and processes of the Business, throughout the world (but excluding Assigned IP and Licensed IP).

          (b) License. Opto-Device shall license, and does hereby license as of the Closing Date, the Opto-Device 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 using the Opto-Device IP, unless otherwise terminated according to the provisions of this IP License Agreement. For the avoidance of doubt, this IP License Agreement does not grant Hitachi or its Wholly-Owned Subsidiaries the right to sublicense the Opto-Device IP and Hitachi and its Wholly-Owned Subsidiaries shall not have the right to sublicense the Opto-Device IP without the prior written consent of Opto-Device, not to be unreasonably withheld, unreasonably delayed or unreasonably conditioned.

          (c) Termination Conditions. Such license shall not be terminated or its exploitation enjoined, until and unless: (i) Hitachi has committed a material breach of its obligations under this IP License Agreement, Opto-Device has given written notice of such breach to Hitachi and such breach remains uncured after the Cure Period, or, in the case of a breach, which cannot be cured within such Cure Period, Hitachi has not instituted within such

9

Cure Period steps necessary to remedy the default and/or thereafter has not diligently pursued the same to completion; or (ii) such a material breach is incurable. 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. 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, 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. 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) Review of Obligations. The obligations set forth in this Section 4 shall expire on the tenth (10th) anniversary of the Closing Date; provided, however, that the license under Opto-Device IP existing as of the tenth (10^th) anniversary of the Closing Date shall continue, under reasonable terms and conditions to be agreed between the parties, until the expiration of all of such Opto-Device IP. Notwithstanding the foregoing, if one (1) of the conditions set forth in Section 4(c) is met, Opto-Device may elect to be completely relieved of its obligations set forth in this Section 4. If Opto-Device elects to be relieved of its obligations under this Section 4, the parties shall renegotiate in good faith and on commercially reasonable terms a new license governing the Opto-Device IP.

          (e) Status of Wholly-Owned Subsidiaries.

               (i) License to Opto-Device 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 Opto-Device in accordance with Section 20 of this IP License Agreement and the license under Opto-Device 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 Opto-Device 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 Opto-Device IP and an entity that ceases to remain a Wholly-Owned Subsidiary of Hitachi shall not have the right to sublicense the Opto-Device IP without the prior written consent of Opto-Device, not to be unreasonably withheld, unreasonably delayed or unreasonably conditioned; provided, however, that to the extent any sublicenses have been granted with Opto-Device’s prior written consent with respect to the Opto-Device 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.

Section 5. Third-Party License Agreements.

          (a) Definition. “Third Party License Agreements” shall mean those rights owned by Hitachi under any license agreements relating to Intellectual Property owned by third parties and related to the Business, throughout the world, that cannot be assigned under the Business Transfer Agreement or licensed under Section 3 hereof. “Existing Third Party License Agreements” are those that are in existence on the Closing Date. “Future Third Party License Agreements” are those entered into after the Closing Date.

          (b) Existing Third Party License Agreements. To the extent that any Existing Third Party License Agreement does not provide for an automatic sublicense to Opto-Device, Hitachi shall, upon Opto-Device’s written request, sublicense, and does hereby sublicense, rights under any such Existing Third Party License Agreements to Opto-Device but only to the extent that Hitachi has the right to make available such rights to Opto-Device, subject to the condition that Opto-Device abides by the terms and conditions of any such Existing Third Party License Agreement. The rights referred to above will be provided to Opto-Device on a fully paid-up, non-exclusive basis, except if royalty payments are necessary based specifically on what is being done by Opto-Device, then Opto-Device shall be liable for such royalty payments. Hitachi shall, upon Opto-Device’s written request, sublicense rights under Existing Third Party License Agreements to OpNext and OpNext’s and Opto-Device’s Wholly-Owned Subsidiaries provided: (i) Opto-Device obtains Hitachi’s reasonable prior written consent; (ii) Hitachi can make available such license rights to OpNext and OpNext’s and Opto-Device’s Wholly-Owned Subsidiaries; and (iii) OpNext and OpNext’s and Opto-Device’s Wholly-Owned Subsidiaries abide by the terms and conditions of such Existing Third Party License Agreements. Notwithstanding the foregoing, if any such sublicense invokes any Japanese tax issues, then Hitachi shall not be obliged to grant a sublicense to OpNext and OpNext’s and Opto-Device’s Wholly-Owned Subsidiaries without entering into a separate agreement with OpNext and such Wholly-Owned Subsidiaries under reasonable terms and conditions to be agreed upon between the relevant parties to address such tax issues. The sublicense provided in this subsection 5(b) is subject to the termination provisions of the Existing Third Party License Agreement. The rights referred to above will be provided to OpNext and such Wholly-Owned Subsidiaries on a fully paid-up, non-exclusive basis, except if royalty payments are necessary based specifically on what is being done by OpNext and such Wholly-Owned Subsidiaries, then Opto-Device shall be liable for or shall cause OpNext and such Wholly-Owned Subsidiaries to be liable for such royalty payments.

          (c) Future Third Party License Agreements. Hitachi shall use Commercially Reasonable Efforts to obtain the right to sublicense rights to Opto-Device under Future Third Party License Agreements, which may be entered into by Hitachi after the Closing Date, subject to the condition that Opto-Device abides by the terms and conditions of such Future Third Party License Agreements. The rights referred to above will be granted to Opto-Device on a fully paid-up, non-exclusive basis, except if royalty payments are necessary based specifically on what is being done by Opto-Device, then Opto-Device shall be liable for such royalty payments. Hitachi shall, upon Opto-Device’s written request, sublicense rights under Future Third Party License Agreements to OpNext and OpNext’s and Opto-Device’s Wholly-Owned Subsidiaries provided: (i) Opto-Device obtains Hitachi’s reasonable prior written consent; (ii) Hitachi can

make available such license rights to OpNext and OpNext’s and Opto-Device’s Wholly-Owned Subsidiaries; and (iii) OpNext and OpNext’s and Opto-Device’s Wholly-Owned Subsidiaries abide by the terms and conditions of such Future Third Party License Agreements. Notwithstanding the foregoing, if such sublicense invokes any Japanese tax issues then Hitachi shall not be obliged to grant a sublicense to OpNext and OpNext’s and Opto-Device’s Wholly-Owned Subsidiaries without entering into a separate agreement with OpNext and such Wholly-Owned Subsidiaries under reasonable terms and conditions to be agreed upon between the relevant parties to address such tax issues. The sublicense provided in this subsection 5(c) is subject to the termination provisions of the Future Third Party License Agreements. The rights referred to above will be provided to OpNext and such Wholly-Owned Subsidiaries on a fully paid-up, non-exclusive basis, except if royalty payments are necessary based specifically on what is being done by OpNext and such Wholly-Owned Subsidiaries, then Opto-Device shall be liable for or shall cause OpNext and such Wholly-Owned Subsidiaries to be liable for such royalty payments.

          Hitachi shall provide an analysis of its Existing Third Party License Agreements that are cross-licenses with major competitors of Opto-Device’s products sold as of the Closing Date, including whether Opto-Device is covered by such cross-license agreement and whether Opto-Device has the option to be covered, or to not be covered, by such cross-license agreement. In addition, within one hundred and eighty (180) days after the Closing Date, Hitachi shall cooperate with Opto-Device in creating a list of all Existing Third Party License Agreements that are material to the Business. Such a list may be amended from time to time to include Future Third Party License Agreements that may be material to the Business, as determined by Hitachi and Opto-Device after reviewing the rights available under such Future Third Party License Agreements. Upon request from Opto-Device, Hitachi shall consult with and provide reasonable assistance to Opto-Device employees with respect to the foregoing. Within one hundred and eighty (180) days after the Closing Date, Hitachi and Opto-Device agree to negotiate in good faith and on a reasonable basis to create a mechanism whereby: (i) Hitachi can, to the extent it becomes aware of or is notified about termination, renegotiation or any other material change under an Existing Third Party License Agreements or Future Third Party License Agreements that Opto-Device includes in its list of material licenses, communicate to Opto-Device within a reasonable period of time information relating to such termination, renegotiation or material change to the rights prior to such events occurring; and (ii) Opto-Device can communicate with Hitachi prior to the termination or material change to the rights available to be sublicensed by Hitachi to Opto-Device under the Existing Third Party License Agreements and under any Future Third Party License Agreements. Both parties agree to cooperate with each other to minimize any impact of such termination and renegotiation events.

          (d) Other Agreements. In the event that Opto-Device or one of its Affiliates obtains a separate license agreement for Intellectual Property related to the Business with the same unrelated third party with which Hitachi had a Third Party License Agreement (“Opto- Device Third Party License Agreement”), Opto-Device will cooperate with and reasonably assist Hitachi in its efforts to obtain a license with that party under substantially the same terms and conditions as those under such Opto-Device Third Party License Agreement it has obtained with such third party. If permitted by the terms of such Opto-Device Third Party License Agreement,

Opto-Device will grant a sublicense of the Intellectual Property rights to Hitachi under such Opto-Device Third Party License Agreement.

          (e) Termination of Obligations. The obligations set forth in this Section 5 shall terminate upon a Change of Control (as defined in the Stockholders’ Agreement, dated July 31, 2001, among OpNext, Hitachi and Clarity Partners, L.P., a Delaware limited partnership, Clarity OpNext Holdings I, LLC, a Delaware limited liability company and Clarity OpNext Holdings II, LLC, a Delaware limited liability company) of Opto-Device.

          (d) Litigation, etc. Except as set forth in Section 11(a), there are no actions, suits, proceedings, orders, investigations or claims pending or, to the best of Hitachi’s Knowledge, threatened against Hitachi, 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 Hitachi 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 Hitachi to consummate the transactions contemplated hereby.

          (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 Opto-Device under Section 3(b) or Section 3(f), respectively, in Opto-Device’s reasonable business judgment and such infringement is material to the Business, Hitachi, in its sole discretion, will protect Opto-Device’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 Opto-Device or (ii) by taking some other appropriate action that will not have a Material Adverse Effect on the ongoing business of Opto-Device; 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.

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 Opto-Device.

Section 7. Covenants of Hitachi. Hitachi covenants and agrees as follows:

          (a) Ordinary Course.

          (c) Confidentiality

With respect to any Third Party License Agreement that may not be properly licensed to Opto-Device because of the failure to obtain a required consent (“Non-Transferred License Agreements”), with respect to which Opto-Device requests Hitachi’s cooperation and with respect to which Hitachi and Opto-Device are unable to obtain a separate agreement between Opto-Device and the other party or parties, OptoDevice 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 Opto-Device, for a period up to six (6) months following the Closing Date; provided that Opto-Device 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.

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 to the counsel of OpNext, Opto-Device and their respective Subsidiaries (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 OptoDevice. 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 Opto-Device 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 Closing. Hitachi shall indemnify Opto-Device and its Affiliates and each of their respective officers, directors, members, stockholders, partners and employees (as applicable) and hold them harmless from any Losses suffered or incurred by any such Indemnified Party from any 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 Closing regardless of the timing of such third party’s claim; provided, however, that such infringement is not attributable to any Opto-Device IP.

               (ii) After 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 Closing, Hitachi and Opto-Device 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 Opto-Device and its Affiliates and each of their respective officers, directors, members, stockholders, partners and employees (as applicable) for a new product design, process or method that is developed after the 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 Closing Date, Assigned IP or Licensed IP, while 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 is caused by the product design introduced by Opto-Device irrespective of whether such OptoDevice 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 Closing, Hitachi shall indemnify Opto-Device 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 Closing Date; and (ii) any breach of any covenant of Hitachi contained in this IP License Agreement requiring performance before or after the Closing Date.

          (d) Indemnification by Opto-Device. From and after the Closing, 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: (i) any breach of any representation or warranty of Opto-Device contained in this IP License Agreement that survives the Closing Date; and (ii) any breach of any covenant of Opto-Device contained in this IP License Agreement requiring performance before or after the Closing Date; and (iii) 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 Closing or the manufacture, distribution, marketing or sale of the Products at any time on or after the 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 17(a)(i), 17(a)(iv), 17(b), 17(c), 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 Business) of the Stock Purchase Agreement for claims brought on or after one (1) year from the 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 17(a)(i), 17(a)(iv), 17(b), 17(c), 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 Business) of the Stock Purchase 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 fifty million Yen (¥ 50,000,000), 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 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 Business) of the Stock Purchase Agreement or Sections 8(g)(i), 8(h) and 8(i)(i) of the OpNext Japan R&D Agreement in the aggregate shall in no event exceed one billion Yen (¥ 1,000,000,000). 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 three million Yen (¥ 3,000,000). To the extent there is a dispute as to whether an asserted claim (i) exceeds the three million Yen (¥ 3,000,000) threshold and/or (ii) exceeds on a cumulative basis an amount equal to fifty million Yen (¥ 50,000,000) 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 therefore, 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) 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, Opto-Device 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 Closing Date, Hitachi and Opto-Device shall mutually agree upon the procedures to be adopted for conducting new product release searches and the parties will consider whether the procedures previously agreed to with respect to OpNext Japan could be adopted for OptoDevice. Between the Closing Date and April 1, 2004, during the design process and prior to putting modifications to, extensions of or new versions of products listed on Exhibit B to the Stock Purchase Agreement on the market, Hitachi will cooperate with Opto-Device to conduct appropriate clearance searches. Hitachi shall provide Opto-Device 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, Opto-Device 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 Opto-Device or Hitachi or Wholly-Owned Subsidiaries (whether or not it is a Wholly-Owned Subsidiary at the time) of Opto-Device or Hitachi (including by operation of law in connection with a merger or sale of stock, or sale of substantially all the assets, of Opto-Device or Hitachi or Wholly-Owned Subsidiaries of Opto-Device or Hitachi) without the prior written consent of the other party and any purported assignment without such consent shall be void and without effect; provided, however, that this IP License Agreement, in its entirety, shall be assignable by Opto-Device (or any successor to Opto-Device) to OpNext or any Wholly-Owned Subsidiary of OpNext.

Section 14. Third-Party Beneficiaries. Opto-Device 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 OpNext and OpNext’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 Opto-Device 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 Closing and shall terminate at the close of business on the first (1st) anniversary of the 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 Opto-Device 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.

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.

     THIS FIRST AMENDMENT TO OPTO-DEVICE IP LICENSE 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.”). All capitalized terms used herein but not defined herein shall have the meaning ascribed to such terms in the IP License Agreement (as defined below).

RECITALS

     WHEREAS, Hitachi and Opto-Device Limited, a corporation organized under the laws of Japan (“Opto-Device”) have entered into that certain Intellectual Property License Agreement dated as of October 1, 2002 (the “IP License Agreement”);

     WHEREAS, Opnext Japan is the successor by merger to Opto-Device and seeks to affirm Hitachi’s consent to the assignment of the IP License Agreement from Opto-Device to Opnext Japan; and

     WHEREAS, Hitachi and Opnext Japan desire to enter into this Amendment to 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:

Section 1. Consent to Assignment.

          Hitachi hereby acknowledges and consents to the assignment of the IP License Agreement from Opto-Device to Opnext Japan. References to Opto-Device throughout the IP License Agreement shall be amended to refer to Opnext Japan. Opnext Japan hereby acknowledges and consents to the assignment of certain of the Licensed Intellectual Property Rights and Future Hitachi IP to Renesas Technology Corp.

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

               (ii) Termination Conditions. Subject to Section 3(d), 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 IP License 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 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. In the event that either party submits the dispute to arbitration, both parties shall cooperate in such binding arbitration in accordance with Exhibit B.

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

               (ii) Minority-Owned Affiliates.

Hitachi shall have the sole discretion to determine which of the five (5) foregoing options Hitachi will exercise in each case. 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.

The license to Opnext Japan IP 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 IP, shall be perpetual.

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

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.

               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.

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

               Section 36. 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 37. Bankruptcy.

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.

Section 4. 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 5. 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 6. 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 7. 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 8. 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 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.
