STOCKHOLDERS’ AGREEMENT

     THIS STOCKHOLDERS’ AGREEMENT (this “Agreement”) is made as of July 31, 2001 by and among OpNext, Inc., a Delaware corporation (the “Company”), Hitachi, Ltd., a corporation organized under the laws of Japan (“Hitachi”), Clarity Partners, L.P., a Delaware limited partnership (“Clarity”), Clarity OpNext Holdings I, LLC, a Delaware limited liability company (“Holdings I”) and Clarity OpNext Holdings II, LLC, a Delaware limited liability company (“Holdings II,” and together with Clarity and Holdings I, the “Clarity Parties,” and each, a “Clarity Party”). Hitachi and the Clarity Parties are collectively referred to herein as “Stockholders.” Capitalized terms used herein are defined in Section 14 hereof.

     WHEREAS, Hitachi and the Clarity Parties desire to jointly own a corporation that will, through its subsidiaries, be the successor to the Business.

     WHEREAS, pursuant to the terms of a Business Transfer Agreement dated as of December 6, 2000, Hitachi made a capital contribution, in the form of a cash payment, to OpNext Japan, Inc., a corporation organized under the laws of Japan and a wholly-owned subsidiary of Hitachi (“OpNext Japan”), and OpNext Japan used such contributed funds to purchase the Business.

     WHEREAS, pursuant to the terms of an Amended and Restated Stock Purchase Agreement (the “Stock Purchase Agreement”), and a Stock Contribution Agreement, each dated as of the date hereof (the “Stock Contribution Agreement”), Hitachi contributed 100% of the equity interests in OpNext Japan to the Company in exchange for 105,000,000 shares of the Company’s Class A Common Stock, par value $0.01 per share, each of which has ten votes per share (the “Class A Common”); and pursuant to the terms of the Stock Purchase Agreement, the Clarity Parties purchased the number of shares of Class A Common set forth next to the name of each Clarity Party on Annex A attached hereto.

     WHEREAS, Hitachi and Clarity presently anticipate that the Company will issue 15% of its equity to employees in the form of stock options, 20% for mergers and acquisitions, 10% in an initial public offering, and 5% to strategic investors, at such times and in such amounts as are approved by the Company’s board of directors.

     WHEREAS, the Company and the Stockholders desire to enter into this Agreement for the purpose, among others, of (i) establishing the composition of the Company’s Board of Directors (the “Board”), (ii) limiting the manner and terms by which the Common Stock may be transferred and (iii) establishing the terms and agreements concerning the parties’ relationships and providing for the corporate governance of the Company. This Agreement is being executed and is becoming effective concurrently with the Closing under the Stock Purchase Agreement.

     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 Agreement hereby agree as follows:

     Section 1. Board of Directors.

     (a) From and after the date hereof and until all of the provisions of this Section 1 cease to be effective, each Stockholder shall vote all of its or his Common Stock and any other Voting Securities of the Company over which such Stockholder has voting control and shall take all necessary or desirable actions within its or his control (whether in its or his capacity as a stockholder, director, member of a Board committee or officer of the Company or otherwise, and including, without limitation, attendance at meetings in person or by proxy for purposes of obtaining a quorum and execution of written consents in lieu of meetings), and the Company shall take all necessary and desirable actions within its control (including, without limitation, calling special Board and stockholder meetings), so that:

     (i) the authorized number of directors on the Board shall be established at five (5) directors;

     (ii) the following Persons shall be elected to the Board on the Closing Date:

     (A) three (3) representatives designated by Hitachi (the “Hitachi Directors”);

     (B) one (1) representative designated by Clarity (the “Clarity Director”); and

     (C) the Chief Executive Officer of the Company (the “Management Director”);

     (iii) the removal from the Board (with or without cause) of any Hitachi Director or Clarity Director shall be at the written request of the Stockholder originally entitled to designate such director, but only upon such written request and under no other circumstances;

     (iv) if the Management Director ceases to be the Chief Executive Officer of the Company, he shall be removed as a director promptly after his employment in such office ceases; and

     (v) in the event that any Hitachi Director, Clarity Director or Management Director ceases to serve as a member of the Board during his/her term of office, the resulting vacancy on the Board shall be filled in the manner provided in subsections 1(a)(ii)(A) through (C) above, as the case may be.

     (b) The Company shall pay the reasonable out-of-pocket expenses incurred by each director in connection with attending the meetings of the Board and any committee thereof.

     (c) The provisions of this Section 1 shall terminate automatically and be of no further force and effect upon the first to occur of (i) an Initial Public Offering or (ii) a Sale of the Company; provided that the parties acknowledge and agree that Clarity shall be entitled to maintain for itself the rights set forth in Section 1(a)(ii)(B), notwithstanding such termination so long as the Clarity Parties and their Affiliates own Voting Securities of the Company possessing more than 10% of the total voting power of all outstanding Voting Securities of the Company.

     (d) If any party fails to designate a representative to fill a directorship pursuant to the terms of this Section 1, and following notice from the Company, the election of an individual to such directorship shall be accomplished in accordance with the Company’s by-laws and applicable law.

     (e) Clarity shall have the right to designate two Observers to the Board, who shall be entitled to attend all meetings of the Board and to receive all notices of Board meetings and other materials distributed to directors, but who shall not be entitled to vote. Notwithstanding the foregoing, Hitachi and the Company shall have the right to withhold from the Observers any confidential information which the Company, Hitachi or the Hitachi Directors deem to be inappropriate to disclose to such Observers (and shall have the right to exclude such Observers from any portion of a board meeting where such confidential information is discussed). Such Observers shall initially be Stephen P. Rader and Fumio Uehara.

     (f) No party has taken or shall take any action that conflicts with, or for the purpose or with the effect of frustrating or circumventing, the provisions of this Section 1, including, without limitation, the grant of a proxy to, or entering into a separate voting agreement with, a third party, without the consent of the other parties.

Following the Closing, for so long as such Stockholder holds any shares of Class A Common, the books and records of the Company shall be maintained in English and the financial accounts shall be kept and stated in US Dollars and US GAAP and the Company shall deliver to each Stockholder:

     (i) Within 45 days after the end of each quarterly accounting period in each fiscal year, unaudited consolidated statements of income and cash flows of the Company and its Subsidiaries for such quarterly period and for the period from the beginning of the fiscal year to the end of such quarter, and unaudited consolidated balance sheets of the Company and its Subsidiaries as of the end of such quarter, setting forth, in each case, comparisons to the Company’s annual budget and to the corresponding period in the preceding fiscal year, and all such statements shall be prepared in accordance with US GAAP, consistently applied, subject to the absence of footnote disclosures and to normal year-end adjustments, and shall be certified by the Company’s chief financial officer;

     (ii) within 90 days after the end of each fiscal year, audited consolidated statements of income and cash flows of the Company and its Subsidiaries for such fiscal year, and audited consolidated balance sheets of the Company and its Subsidiaries as of the end of such fiscal year, setting forth in each case comparisons to the Company’s annual budget and to the preceding fiscal year, all prepared in accordance with US GAAP, consistently applied;

     (iii) at least ten days prior to the beginning of each fiscal year, an annual budget prepared on a monthly basis with respect to statements of income and on a quarterly basis with respect to cash flows and balance sheets for the Company and its Subsidiaries for such fiscal year (displaying anticipated statements of income and cash flows and balance sheets), and promptly upon preparation thereof any other significant budgets prepared by the Company and any revisions of such annual or other budgets, and within 30 days after any such period in which there is a material deviation from the annual budget, an Officer’s Certificate explaining the deviation and what actions the Company has taken and proposes to take with respect thereto; and

     (iv) promptly (but in any event within five Business Days) after the discovery or receipt of notice thereof, any default under or breach of, any material agreement to which it or any of its Subsidiaries is a party, any condition or event which is reasonably likely to result in any material liability under any statute or regulation relating to public health and safety, worker health and safety or pollution or protection of the environment or any other material adverse change, event or circumstance affecting the Company or any Subsidiary (including, without limitation, the filing of any material litigation against the Company or any Subsidiary or the existence of any dispute with any Person which involves a reasonable likelihood of such litigation being commenced), and

an Officer’s Certificate specifying the nature and period of existence thereof and what actions the Company and its Subsidiaries have taken and propose to take with respect thereto;

     (v) with reasonable promptness, such other information and financial data concerning the Company and its Subsidiaries as any Person entitled to receive information under this Section 3(a) may reasonably request.

     Notwithstanding the foregoing, the provisions of this Section 3(a) shall cease to be effective so long as the Company (i) is subject to the periodic reporting requirements of the Securities Exchange Act and continues to comply with such requirements and (ii) promptly provides to each Person otherwise entitled to receive information pursuant to this Section 3(a) all reports and other materials filed by the Company with the Securities and Exchange Commission pursuant to the periodic reporting requirements of the Securities Exchange Act; provided that so long as any shares of Class A Common remain outstanding, the Company shall continue to deliver to each Stockholder (so long as such Stockholder holds any Class A Common) the information specified in subsection 3(a)(iv).

     Except as otherwise required by law or judicial order or decree or by any governmental agency or authority, each Person entitled to receive information regarding the Company and its Subsidiaries under Section 3(a) shall use its best efforts to maintain the confidentiality of all nonpublic information obtained by it hereunder which the Company has reasonably designated as proprietary or confidential in nature; provided that each such Person may disclose such information in connection with the sale or permitted transfer of any Common Stock if such Person’s transferee agrees in writing to be bound by the provisions hereof. Notwithstanding the foregoing, the parties to this Agreement acknowledge that they are subject to nondisclosure obligations under the other Collateral Agreements, and agree that no party may obtain or disclose any information hereunder in order to avoid such party’s obligations under such other Collateral Agreements.

Subject to the final paragraph of Section 3(a), the Company shall permit any representatives designated by a Stockholder (so long as such Stockholder holds any Class A Common), upon reasonable notice and during normal business hours, to (i) visit and inspect any of the properties of the Company and its Subsidiaries, (ii) examine the corporate and financial records of the Company and its Subsidiaries and make copies thereof or extracts therefrom and (iii) discuss the affairs, finances and accounts of any such corporations with the directors, officers, key employees and independent accountants of the Company and its Subsidiaries. The presentation of an executed copy of this Agreement by any such Stockholder to the Company’s independent accountants shall constitute the Company’s permission to its independent accountants to participate in discussions with such Persons.

     (c) Current Public Information. At all times after the Company has filed a registration statement with the Securities and Exchange Commission pursuant to the requirements of either the Securities Act or the Securities Exchange Act, the Company shall file

all reports required to be filed by it under the Securities Act and the Securities Exchange Act and the rules and regulations adopted by the Securities and Exchange Commission thereunder and shall take such further action to the extent required to enable the sale of securities of the Company pursuant to (i) Rule 144 adopted by the Securities and Exchange Commission under the Securities Act (as such rule may be amended from time to time) or any similar rule or regulation hereafter adopted by the Securities and Exchange Commission or (ii) a registration statement on Form S-2 or S-3 or any similar registration form hereafter adopted by the Securities and Exchange Commission.

     (d) Consultation With Clarity. In the preparation of its annual business plan and budget, representatives of the Company shall consult with Clarity and shall in good faith consider the views expressed by Clarity with respect to such plan and budget.

     (e) Place of Business. The parties acknowledge that the Company will have its principal place of business in the United States. It is agreed that such principal place of business initially will be in the State of New Jersey.

     Section 4. Accounting Consolidation Matters.

     (a) The parties acknowledge their mutual intention that, except as specified below and subject to the terms of this Section 4, Hitachi shall continue to own such voting and equity ownership interest in the Company and shall have such other management rights as are necessary in the reasonable professional opinion of Hitachi’s independent public accountants to permit Hitachi to consolidate the accounts of the Company for purposes of publicly reporting Hitachi’s financial results in the United States and in Japan and in connection with Hitachi’s issuance of securities (as determined in accordance with both US GAAP and Japanese GAAP). The provisions of this Section 4 shall be construed in accordance with the foregoing statement of intention.

     (b) Without the prior written consent of Hitachi, the Company shall not:

     (i) issue any equity securities (or any securities convertible into or exchangeable for equity securities), which issuance would cause Hitachi to own, directly or indirectly, in the aggregate less than a majority of the Voting Securities of the Company on a fully-diluted basis; provided that, in the event that a different percentage is necessary to permit consolidation (as determined in accordance with both US GAAP and Japanese GAAP), then such percentage shall be substituted for the foregoing percentage and, if necessary, Hitachi shall be afforded the rights under paragraph (c) below in order to increase its percentage ownership; or

     (ii) otherwise take or fail to take any action that would have the result (as determined in accordance with either US GAAP or Japanese GAAP) that Hitachi is unable to consolidate the Company for purposes of reporting Hitachi’s financial results (as determined in accordance with both US GAAP and Japanese GAAP); provided that,

in the event of a change in US GAAP or Japanese GAAP such that it is impossible or unreasonably difficult or disadvantageous to the Company for the Company to take or fail to take such action and Hitachi may continue to consolidate the Company’s results of operations by increasing its ownership interest in the Company, Hitachi shall be limited to the rights under paragraph (c) below.

     (c) In the event that Hitachi determines to consent to any issuance of securities in a Dilutive Transaction or in the event of a Change in Consolidation GAAP, then Hitachi shall have the right to purchase additional Class A Common or other securities, as the case may be, from the Company in order to maintain its ownership percentages at the level necessary to permit Hitachi to continue to consolidate the Company’s financial results. If Hitachi proposes to exercise such right, it may at its election purchase either Class A Common or, in the case of a Dilutive Transaction, the type of security that is being issued in the Dilutive Transaction. Any such purchase shall be for cash. The purchase price shall be the same price as is being paid in (or, in the case of a convertible or exchangeable security or an acquisition of property rights or a business, implied by) the Dilutive Transaction (as reflected in the Company’s financial reporting) or, if such price is not readily ascertainable or there is a Change in Consolidation GAAP, shall be the fair value of such Common Stock or other security as mutually agreed upon by Clarity or Hitachi. If no such agreement is reached within 30 days of Hitachi’s determination to exercise its rights under this paragraph, then the price at which such securities may be purchased by Hitachi shall be determined by an independent investment banker appointed by the Board.

     (d) In the event of any Change in Consolidation GAAP, Hitachi shall, as promptly as practicable prior to exercising its rights hereunder, provide to the Clarity Parties the written opinion of its independent outside accountant, in form and substance reasonably acceptable to Clarity, setting forth the nature of the Change in Consolidation GAAP and their view that such change requires one or more of the actions contemplated by this Section 4 in order to permit Hitachi to continue to consolidate the accounts of the Company.

     (e) For purposes of this Section 4, “US GAAP” means generally accepted accounting principles as in effect from time to time in United States and generally applicable to Japanese companies that are publicly traded in the United States or are offering securities in the United States, applied on a basis consistent in all material respects (except for changes concurred in by Hitachi’s independent public accountants) with the most recent audited consolidated financial statements of Hitachi as are publicly released in United States or are required to be filed or publicly disclosed in the United States to permit the sale of securities; “Japanese GAAP” means generally accepted accounting principles as in effect from time to time in Japan and generally applicable to Japanese companies that are publicly traded in Japan or are offering securities in Japan, applied on a basis consistent in all material respects (except for changes concurred in by Hitachi’s independent public accountants) with the most recent audited consolidated financial statements of Hitachi as are publicly released in Japan or are required to be filed or publicly disclosed in Japan to permit the sale of securities; “Dilutive Transaction” means the issuance of securities in any transaction or series of related transactions that would

result in Hitachi’s ownership being reduced below the percentage threshold set forth in subsection (i) of Section 4(b) above; and a “Change in Consolidation GAAP” means a change in US GAAP or Japanese GAAP such that a different percentage than that set forth in subsection (i) of Section 4(b) above shall be required in order for Hitachi to continue to consolidate the results of the Company for financial reporting purposes or such that the circumstances contemplated by the proviso to subsection (b)(ii) above shall occur.

     Section 5. Freedom of Action. The Company and the Stockholders expressly acknowledge that, subject to the confidentiality provisions of the final paragraph of Section 3(a) and the non-compete provisions of Section 12, (i) the Stockholders and their respective Affiliates are permitted to have, and may presently or in the future have, businesses, investments or other business relationships with entities engaged in the Business other than through the Company or any of its Subsidiaries (an “Other Business”), (ii) the Stockholders and their respective Affiliates have and may develop businesses or strategic relationships with businesses that are and may be competitive or complementary with the Company or any of its Subsidiaries, (iii) none of the Stockholders and their respective Affiliates will be prohibited by virtue of their investments in the Company or its Subsidiaries or their service on the Board from pursuing and engaging in any such activities, (iv) none of the Stockholders and their respective Affiliates will be obligated to inform the Company or the Board of any such opportunity, relationship or investment, (v) the Company, the other Stockholders and their respective Affiliates and any future stockholders will not acquire or be entitled to any interest or participation in any Other Business as a result of the participation therein of any Stockholder, or any of its Affiliates, and (vi) the involvement of the Stockholders and their respective Affiliates in any Other Business will not constitute a conflict of interest by such Persons with respect to the Company or any of its Subsidiaries or the other Stockholder or any of its Affiliates. For purposes of this Section 5, the Stockholders and the Company acknowledge and agree that, with respect to the Clarity Parties or their Permitted Transferees, the term “Affiliates” shall be deemed to include (in addition to Persons otherwise constituting “Affiliates” as defined in Section 14 hereof) any of the investors or other owners of (i) any Clarity Party and/or its Affiliates and (ii) the predecessor fund of Clarity and the Affiliates of such predecessor fund.

     Section 6. Qualified Public Offering.

     (a) IPO Request Notice. Within ten days of a written request by a Stockholder (an “IPO Request Notice”), the parties hereby agree to pursue and complete as promptly as possible thereafter a Qualified Public Offering; provided that, in order to constitute a valid IPO Request Notice for purposes hereof, such request must be accompanied by a written letter from one or more of the investment banking firms identified on Schedule 6(a) attached hereto, which letter states that, in their reasonable judgment, based on then current market conditions, it is reasonably likely that a Qualified Public Offering can be successfully consummated; provided further that the preceding provision shall be applicable only if the Company is cooperating by providing such investment banking firms with such information as is reasonably requested by such investment banking firms, subject to the Company’s receipt of an appropriate confidentiality agreement from such firms. Without limiting the generality of the

foregoing, the parties agree to vote, and to cause their respective designees to the Board to vote, in favor of any such Qualified Public Offering.

     (b) Cooperation; Filings. Following receipt of any IPO Request Notice, the Stockholders and the Company shall promptly cooperate in preparing, and shall use reasonable efforts to cause the Company to promptly file with the Securities and Exchange Commission (the “SEC”), a registration statement on Form S-1 with respect to the issuance of common stock of the Company (such Form S-1, and any amendments or supplements thereto, the “Form S-1”) and to cause the shares to be approved for listing on the New York Stock Exchange or for quotation on The Nasdaq Market, Inc. National Market (NASDAQ), subject to official notice of issuance. Hitachi shall provide the Company with such accounting support as is commercially practicable and reasonable as the predecessor of the Business. The terms of the Qualified Public Offering shall be, unless agreed by Hitachi and Clarity, as recommended by the underwriters taking into account market conditions.

     (c) Comments; Amendments. Each of the Stockholders and the Company shall use reasonable best efforts to have the Form S-1 declared effective by the SEC and to keep the Form S-1 effective as long as is necessary to consummate the Qualified Public Offering. The Stockholders and the Company agree that each shall, as promptly as practicable after receipt thereof, provide the other parties copies of any written comments and advise the other parties of any oral comments, with respect to the Form S-1 received from the SEC. The parties shall cooperate and provide the other with a reasonable opportunity to review and comment on any amendment or supplement to the Form S-1 prior to filing such with the SEC and will provide each other with a copy of all such filings made with the SEC. Notwithstanding any other provision herein to the contrary, no amendment or supplement (including by incorporation by reference) to the Form S-1 shall be made without the approval of the Stockholders, which approval shall not be unreasonably withheld or delayed. Each of the Stockholders shall furnish all information concerning it and the holders of its capital stock as may be reasonably requested in connection with preparation of the Form S-1.

     (d) Effectiveness, etc. Each party will advise the other parties, promptly after it receives notice thereof, of the time when the Form S-1 has become effective, the issuance of any stop order, the suspension of the qualification of the Common Stock of the Company for offering or sale in any jurisdiction, or any request by the SEC for amendment of the Form S-1. If at any time prior to such effective time any information relating to any Stockholder, or any of such Stockholder’s respective Affiliates, officers, directors, partners or members, should be discovered by such Stockholder, which information should be set forth in an amendment or supplement to the Form S-1 (or any preliminary prospectus included therein) so that any of such documents would not include any misstatement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, the party which discovers such information shall promptly notify the other parties hereto and, to the extent required by law, rules and regulations, an appropriate amendment or supplement describing such information shall be promptly filed with the SEC and disseminated to prospective purchasers of securities in the offering. The parties further agree to

prepare, execute and deliver such documents, financial statements and agreements, including without limitation a customary lock-up agreement, as are required by relevant securities laws, the rules of the applicable securities exchange, the underwriters or as are necessary or desirable to effect a Qualified Public Offering.

     (e) Definition of Qualified Public Offering. For purposes of this Section, “Qualified Public Offering” means a public offering of common stock of the Company, that is to be firmly underwritten by any one or more of the internationally recognized investment banking firms set forth on the list of investment banking firms referenced in Subsection (a), pursuant to a registration statement on Form S-1 under the Securities Act, provided that (i) the pre-money valuation of the total equity of the Company on a fully diluted basis is reasonably expected to be, at the time of the investment bank’s proposal, at least equal to (A) $1.786 billion during the three-year period immediately following the Closing or (B) $2.5 billion thereafter and (ii) the aggregate gross proceeds to the Company are reasonably expected to be, at the time of the investment bank’s proposal, not less than (A) $125 million (before deducting underwriting discounts or commissions), during the three-year period immediately following the Closing or (B) $175 million thereafter (before deducting underwriting discounts or commissions).

     (f) Abandonment of a Qualified Public Offering. Notwithstanding the foregoing provisions of this Section 6, in the event that a registration initiated as a Qualified Public Offering is not able to be consummated consistent with the requirements of, and at or above the thresholds provided in, the definition of a Qualified Public Offering, then the Board may determine to abandon the proposed Qualified Public Offering.

     (g) Holdback. Notwithstanding the foregoing provisions of this Section 6, the Company may postpone for up to 120 days from the date of the IPO Request Notice either the filing or the effectiveness of a registration statement for a Qualified Public Offering if the Board has determined and promptly notifies the Stockholders in writing that in its reasonable good faith judgment (i) a material event has occurred or is likely to occur with respect to the Company or one of its Subsidiaries that has not been publicly disclosed and, if disclosed, could reasonably be expected to materially and adversely affect the Company and its ability to consummate the Qualified Public Offering or (ii) the Qualified Public Offering could reasonably be expected to interfere with any financing, acquisition or corporate reorganization involving the Company. The Company may not exercise its rights to delay a Qualified Public Offering hereunder more than once in any twelve-month period.

     Section 7. Restrictions on Transfer of Stockholder Shares.

     (a) Transfer by Hitachi of Stockholder Shares. Subject to the terms of this Section 7, Hitachi and its Permitted Transferees to which it transfers Stockholder Shares shall not Transfer any interest in their respective Stockholder Shares to a Person other than to a Permitted Transferee, until the earliest of (i) the fifth anniversary of the Closing Date and (ii) the consummation of a Qualified Public Offering; provided that thereafter, Hitachi and its Permitted Transferees shall have no restriction on the Transfer of their respective Stockholder Shares other

than restrictions imposed by applicable laws or regulations and/or as expressly set forth in this Agreement and such shares shall not be pledged.

     (b) Transfer by the Clarity Parties of Stockholder Shares. No Clarity Party shall Transfer any interest in its Stockholder Shares to a Person other than to a Permitted Transferee, except pursuant to the provisions of this Section 7 or Section 8, 9, 10 or 11 hereof or pursuant to a Public Sale.

     (c) Conversion of Class A Common. Notwithstanding anything contained to the contrary herein, each Stockholder agrees that, prior to any Transfer of Common Stock to any Person (other than a Transfer to Hitachi or to a Permitted Transferee), and as a condition to such Transfer, it will convert such shares that are shares of Class A Common into shares of Class B Common pursuant to the terms set forth in the Company’s Certificate of Incorporation.

     (d) Condition to Transfer. Prior to any Transfer of Stockholder Shares (other than pursuant to a Public Sale or a Sale of the Company) to any Person that is consummated prior to a Qualified Public Offering, and as a condition to such Transfer, the transferring holder of Stockholder Shares shall cause the prospective transferee to be bound by this Agreement and (if such Permitted Transferee was not previously a party to this Agreement) to execute and deliver to the Company and the other Stockholders a counterpart of this Agreement. The restrictions contained in this Agreement will continue to be applicable to each Stockholder Share after any Transfer, and in the event of any Transfer of Stockholder Shares to any Person, such subsequent holder (other than a Company) of Stockholder Shares shall be deemed to be a “Stockholder” for the purposes of this Agreement upon such transferee’s execution and delivery of a counterpart to this Agreement (if the transferee was not previously a party to this Agreement).

     (e) Violations. Any Transfer or attempted Transfer of any Stockholder Shares in violation of any provision of this Agreement shall be void, and the Company shall not record such Transfer on its books or treat any purported transferee of such Stockholder Shares as the owner of such shares for any purpose.

     (f) Permitted Transfers. Except as set forth in Section 7(d) hereof, the restrictions set forth in this Section 7 shall not apply with respect to any Transfer of Stockholder Shares by any Stockholder to or among its Affiliates (collectively referred to herein as “Permitted Transferees”); provided that the restrictions contained in this Section 7 shall continue to be applicable to the Stockholder Shares after any such Transfer. Notwithstanding the foregoing, no party hereto shall avoid the provisions of this Agreement by making one or more transfers to one or more Permitted Transferees and then disposing of all or any portion of such party’s interest in any such Permitted Transferee. For purposes of this Agreement, the Stockholders and the Company acknowledge and agree that, with respect to the Clarity Parties or their Permitted Transferees, the term “Affiliates” shall be deemed to include (in addition to Persons otherwise constituting “Affiliates” as defined in Section 14 hereof) any of the investors or other owners of (i) any Clarity Party and/or its Affiliates and (ii) the predecessor fund of

Clarity and the Affiliates of such predecessor fund, and the Clarity Parties or such Permitted Transferees shall be entitled to transfer the Stockholder Shares to such Affiliates pursuant to the terms of this Section 7.

     Section 8. Transfer Prior to an Initial Public Offering.

     (a) During the period beginning on the third anniversary of the Closing and ending upon the consummation of an Initial Public Offering, each Clarity Party may Transfer its Stockholder Shares pursuant to the terms of this Section 8.

     (b) Prior to making any Transfer of any Stockholder Shares (other than a Public Sale), each Clarity Party proposing to Transfer any of its Stockholder Shares shall deliver a written notice (an “Offer Notice”) to the Company and Hitachi. The Offer Notice shall disclose in reasonable detail the proposed number of Stockholder Shares to be transferred, the proposed terms and conditions of the Transfer, the identity of the prospective transferee(s) (if known) and valuation of such Stockholder Shares to be transferred.

     (c) If such Clarity Party is offering to sell all of its Stockholder Shares pursuant to the Offer Notice, then the Company may elect to purchase all (but not less than all) of the Stockholder Shares specified in the Offer Notice, at a price equal to the aggregate valuation contained in the Offer Notice for such Stockholder Shares and on the terms specified in the Offer Notice, by delivering written notice of such election to such Clarity Party and Hitachi as soon as practical, but in any event within 15 Business Days after the date on which the Offer Notice is received by the Company and Hitachi. If the Offer Notice covers less than all of such Clarity Party’s Stockholder Shares or the Company has not elected to purchase all such Stockholder Shares within such 15 Business-Day period, then Hitachi may elect to purchase all (but not less than all) of the Stockholder Shares specified in the Offer Notice, at a price equal to the aggregate valuation contained in the Offer Notice for such Stockholder Shares and on the terms specified in the Offer Notice, by delivery of written notice of such election to such Clarity Party, the Company and each other Stockholder (other than Hitachi) as soon as practical but in any event within 15 Business Days after receipt of the Offer Notice by the Company and Hitachi. If the Company or Hitachi has elected to purchase Stockholder Shares from such Clarity Party, the transfer of such shares shall be consummated as soon as practical after the delivery of its election to purchase to such Clarity Party, but in any event within 15 Business Days after the expiration of such 15-Business-Day election period. If Hitachi and, if applicable, the Company have not elected to purchase all of the Stockholder Shares within their election period, such Clarity Party may, within 60 days after the expiration of such election period and subject to the provisions of subsection (d) below, transfer such Stockholder Shares to one or more third parties (other than a Competitor) at a price no less than the aggregate valuation contained in the Offer Notice for such Stockholder Shares and on other terms no more favorable to the transferees thereof than offered to the Company and, if applicable, Hitachi in the Offer Notice. Any Stockholder Shares not transferred within such 60 day period shall be subject to a new Offer Notice and reoffered to the Company and Hitachi under this Section 8 prior to any subsequent Transfer. The purchase price specified in any Offer Notice shall be payable solely in cash at the

closing of the transaction or, at such Clarity Party’s election, in installments over time, and no Stockholder Shares may be pledged.

     (d) The provisions of this Section 8 will not apply to Transfers of Stockholder Shares by the Stockholders (i) to or among any of their Permitted Transferees or (ii) pursuant to Sections 10 or 11 hereof.

     Section 9. Transfer Following an Initial Public Offering.

     (a) Following the consummation of an Initial Public Offering, each Clarity Party may Transfer its Stockholder Shares subject to the terms of this Section 9.

     (b) If at any time following consummation of an Initial Public Offering any Clarity Party or Clarity Parties propose to Transfer Stockholder Shares which represent more than 5% of the total number of shares of Common Stock then outstanding (other than in a Public Sale), prior to making any such Transfer, such Clarity Parties shall deliver an Offer Notice to the Company and Hitachi via facsimile or electronic transmission with receipt confirmed. The Offer Notice shall disclose in reasonable detail the proposed number of Stockholder Shares to be transferred, the proposed terms and conditions of the Transfer and the identity of the prospective transferee(s) (if known). If such Clarity Parties are offering to sell all of their Stockholder Shares pursuant to the Offer Notice, then the Company may elect to purchase all (but not less than all) of the Stockholder Shares specified in the Offer Notice at the price and on the terms specified therein by delivering written notice of such election to such Clarity Parties and Hitachi as soon as practical but in any event within five Business Days after the delivery of the Offer Notice to the Company and Hitachi via facsimile or electronic transmission with receipt confirmed. If the Offer Notice covers less than all of such Clarity Parties’ Stockholder Shares or the Company has not elected to purchase all of the Stockholder Shares within such five-Business-Day period, then Hitachi may elect to purchase all (but not less than all) of the Stockholder Shares specified in the Offer Notice at the price and on the terms specified therein by delivering written notice of such election to such Clarity Parties and the Company as soon as practical but in any event within five Business Days after such delivery of the Offer Notice. If the Company or, if applicable, Hitachi has elected to purchase Stockholder Shares from such Clarity Parties, the transfer of such shares shall be consummated as soon as practical, but in any event within five Business Days after the expiration of the election period of Hitachi and, if applicable, the Company. If Hitachi and, if applicable, the Company have not elected to purchase all of the Stockholder Shares being offered, such Clarity Parties may, within five Business Days after the expiration of such election period and subject to the provisions of subsection (d) below, transfer such Stockholder Shares to one or more third parties (other than a Competitor) at a price no less than the price per share specified in the Offer Notice and on other terms no more favorable to the transferees thereof than offered to the Company and Hitachi in the Offer Notice. Any Stockholder Shares not transferred within such five-Business-Day period shall be reoffered to the Company and Hitachi under this Section 9 prior to any subsequent Transfer. The purchase price specified in any Offer Notice shall be payable solely in cash at the

closing of the transaction or, at such Clarity Party’s election, in installments over time, and no Stockholder Shares may be pledged.

     (c) The provisions of Section 9(b) will not apply to Transfers of Stockholder Shares by the Stockholders (i) to or among any of their Permitted Transferees or (ii) pursuant to Sections 10 or 11 hereof.

     (d) The provisions of Sections 9(b) and 9(c) shall continue with respect to each Stockholder Share until the earliest of (i) the date on which such Stockholder Share has been transferred in a Public Sale, and (ii) the consummation of a Sale of the Company.

     Section 10. Call Option.

     (a) In the event that, on or after the fifth anniversary of the Closing, a proposed action of the Company or any Subsidiary that is subject to Section 2(b) is submitted to the Board for consideration and such action is both supported by the Hitachi Directors and rejected by the Clarity director at two consecutive regularly scheduled Board meetings and, as a result, the Board has affirmatively rejected the proposed action, then the Company shall have the right to purchase all (but not less than all) of the Stockholder Shares held by the Clarity Parties by delivering written notice to the Clarity Parties within 60 days of the date of such final rejection (the “Call Date”); provided, however, Hitachi shall not be entitled to exercise this right if such rejected action required any Clarity Party to extend capital to, or otherwise incur liabilities (contingent or otherwise) on behalf or for the benefit of the Company or any of its Subsidiaries, or to grant any liens on any of the property of any Clarity Party.

     (b) Upon delivery of the notice specified in subsection (a), the Company and the Clarity Parties shall promptly determine the Call Price hereunder, and within 60 days after the Call Price has been determined, the Company shall purchase and each Clarity Party shall sell such Clarity Party’s Stockholder Shares for an amount equal to the Call Price of such Stockholder Shares (in immediately available US funds) and the closing of such sale shall take place at a mutually agreeable time and place. At the time of sale, each Clarity Party shall deliver to the Company duly executed instruments transferring title to such Clarity Party’s Stockholder Shares free and clear of all liens and encumbrances, against payment therefor by certified check payable to such Clarity Party or by wire transfer of immediately available funds to an account designated by such Clarity Party.

     (c) As used in this Section 10 the term “Call Price” shall mean an amount equal to 105% of the aggregate Fair Market Value of the Stockholder Shares to be purchased pursuant to this Section 10, which shall be determined as of the Call Date.

     (d) The Company may, in its sole discretion, assign to Hitachi its right to purchase Stockholder Shares pursuant to this Section 10.

     (e) The provisions of this Section 10 shall terminate upon the earliest of (i) the consummation of a Sale of the Company and (ii) the consummation of an Initial Public Offering.

     Section 11. Purchase of the Clarity Parties’ Stockholder Shares by the Company.

     (a) The Company shall have the obligation to purchase or otherwise acquire the Stockholder Shares held of record by the Clarity Parties at such times, in such manner and for such consideration as set forth below in this Section 11.

     (b) At any time during the two-year period beginning on the earliest to occur of (x) the third anniversary of the Closing Date or (y) a Change of Control of Hitachi, Clarity may demand a determination of the Fair Market Value (a “Determination Notice”) for purposes of this Section 11. After the receipt of any Determination Notice, the Company and Clarity shall promptly determine the Fair Market Value hereunder and within 30 days after the Fair Market Value has been determined, Clarity may demand purchase of the Stockholder Shares held by the Clarity Parties (the “Put Notice”), in whole or in part, at an amount equal to the Put Price by notice to the Company; provided that the Clarity Parties shall be entitled to no more than one demand pursuant to this Section 11. The Put Price shall be payable by the Company in U.S. dollars to the Clarity Parties on the twentieth Business Day after receipt of the Put Notice by wire transfer of immediately available funds to the account(s) designated by the Clarity Parties upon surrender of certificates representing the Stockholder Shares that are the subject of such Put Notice.

     (c) As used in this Section 11, the term “Put Price” shall mean an amount equal to 95% of the aggregate Fair Market Value of the securities to be purchased pursuant to the Put Notice, which shall be determined as of the date of the Determination Notice.

     (d) The Company may, in its sole discretion, assign to Hitachi its obligation to repurchase Stockholder Shares pursuant to this Section 11.

     (e) Hitachi hereby irrevocably and unconditionally guarantees to the Clarity Parties the full and punctual performance of the Company’s obligation to purchase Stockholder Shares from the Clarity Parties under this Section 11, in case of the Company’s failure to perform such obligations for any reason, including without limitation the Company being precluded from performing its obligation as a matter of law or otherwise. Hitachi hereby agrees that its obligations hereunder are separate and independent of the obligations of the Company and shall be as primary obligor, and not as surety, and such guarantee shall be unaffected by any invalidity, irregularity or unenforceability of this Section 11, any failure to enforce the provisions of this Section 11, the discontinuance of Hitachi’s ownership interest in the Company or any merger or reorganization or similar event or proceeding affecting the Company or any waiver, modification, amendment, consent or indulgence granted to the Company with respect thereto by the Clarity Parties, the recovery of any judgment against the Company or any action to enforce the same, or any other circumstances which may otherwise constitute a legal or equitable defense

to or discharge of the obligations of a surety or a guarantor. Hitachi hereby waives any right to require the Clarity Parties to first proceed against or attempt to collect or require performance from the Company. This Guarantee is a guarantee of payment and performance and not of collection. All payments hereunder shall be made free and clear of, and without deduction or withholding for or on account of, any taxes, levies, fees, imposts, duties, expenses, commissions, withholdings, assessments or other charges.

     (f) The provisions of this Section 11 shall terminate upon the earliest of (i) the consummation of a Sale of the Company, (ii) the consummation of an Initial Public Offering and (iii) the closing of the Company’s purchase of the Stockholder Shares of the Clarity Parties pursuant to a Purchase Notice in accordance with the terms of this Section 11.

     Section 12. Nonsolicitation and Noncompetition.

     (a) During the period beginning on the Closing and ending at the earlier of (i) one year after the date of an Initial Public Offering and (ii) such time as Hitachi and its Permitted Transferees no longer hold at least a majority of the Voting Securities of the Company, Hitachi shall not, and shall cause its Subsidiaries to not, participate or engage in or otherwise invest in, directly or indirectly, any area of the world, the business of designing, developing, manufacturing (or having manufactured), marketing, distributing or selling the following fiber optical products, in each case which are dedicated to use in or intended to be used in telecommunications applications (“Restricted Products”): transmitters, receivers, transceivers, laser diode modules, photo diode modules, parallel optical interconnectors, lasers, photodiodes, modulators, amplifier modules, optical switches and optical wave guides.

     (b) Notwithstanding anything in Section 12(a) to the contrary but subject to the additional restrictions and obligations set forth in the SIC Letter Agreement:

     (i) Hitachi and its Affiliates shall be permitted to design, develop, manufacture (or have manufactured), market, distribute and sell Restricted Products through its SIC;

     (ii) Hitachi and its Affiliates shall be permitted to design, develop, manufacture (or have manufactured), market, distribute and sell any Restricted Products that Hitachi or any Affiliate of Hitachi may be designing, developing, manufacturing (or having manufactured), marketing, distributing or selling on the Closing Date;

     (iii) The provisions of this Section 12 shall not restrict in any manner the activities of (A) Hitachi Cable, Ltd. and its subsidiaries, (B) any other present entities which currently have publicly traded equity securities outstanding and which are listed on Schedule 12(b)(iii) including their subsidiaries, (C) any future entities which may issue or have publicly traded equity securities outstanding and which are not wholly owned by Hitachi, and (D) any present or future joint ventures to which Hitachi or any of its entities previously described in this clause (iii) is a party; and

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

     (c) The parties hereto recognize that the laws and public policies of various jurisdictions may differ as to the validity and enforceability of covenants similar to those set forth in this Section 12. Hitachi acknowledges that the provisions of this Section 12 are reasonable and necessary to protect and preserve the business of the Company, that the Clarity Parties entered into this Agreement and the Stock Purchase Agreement on the basis of this provision and that the Company and the Clarity Parties would be irreparably damaged if Hitachi were to breach the covenants set forth in this Section 12. It is the intention of the parties that the provisions of this Section 12 be enforced to the fullest extent permissible under the laws and policies of each jurisdiction in which enforcement may be sought, and that the unenforceability (or the modification to conform to such laws or policies) of any provisions of this Section 12 shall not render unenforceable, or impair, the remainder of the provisions of this Section 12. Accordingly, if any provision of this Section 12 shall be determined to be invalid or unenforceable, such invalidity or unenforceability shall be deemed to apply only with respect to the operation of such provision in the particular jurisdiction in which such determination is made and not with respect to any other provision or jurisdiction.

     (d) The parties hereto acknowledge and agree that any remedy at law for any breach of the provisions of this Section 12 would be inadequate, and Hitachi hereby consents to the granting by any court of an injunction or other equitable relief, without the necessity of actual monetary loss being proved, in order that the breach or threatened breach of such provisions may be effectively restrained.

     (e) Hitachi acknowledges that its current customary practice is to request the approval of the general manager of any division or Subsidiary of Hitachi prior to soliciting or hiring any employee of such division or Subsidiary, and Hitachi will use its best efforts to continue this customary practice with respect to the Business on and after the Closing Date.

     (f) The parties acknowledge that nothing in this Section 12 is intended to restrict Hitachi or any of its Affiliates from continuing or seeking to do business with any Person

who is a customer or supplier of the Company, subject to compliance the noncompetition provisions of this Section 12 and the SIC Letter Agreement.

     Section 13. Legends.

     (a) Each certificate evidencing Stockholder Shares and each certificate issued in exchange for or upon the transfer of any Stockholder Shares (if such shares remain Stockholder Shares after such transfer) shall be stamped or otherwise imprinted with a legend in substantially the following form:

“The securities represented by this certificate are subject to a Stockholders’ Agreement dated as of July 31, 2001 among the issuer of such securities (the “Company”) and certain of the Company’s stockholders, as amended and modified from time to time. A copy of such Stockholders’ Agreement shall be furnished without charge by the Company to the holder hereof upon written request.”

The Company shall imprint such legend on certificates evidencing Stockholder Shares outstanding as of the date hereof. The legend set forth above shall be removed from the certificates evidencing any shares which cease to be Stockholder Shares.

     (b) Until (a) the securities represented by such certificate are effectively registered under the Securities Act or (b) the holder of such securities delivers to the Corporation a written opinion of counsel in form and substance reasonably satisfactory to the Board to such holder to the effect that such legend is no longer necessary under the Securities Act, the Corporation will cause each certificate representing its securities to be stamped or otherwise imprinted with a legend to substantially the following effect:

“The securities represented by this certificate have not been registered under the Securities Act of 1933, as amended, and thus may not be transferred unless so registered or unless an exemption from registration is available.”

     Section 14. Definitions.

     “Affiliate” of any particular Person means any other Person controlling, controlled by or under common control with such particular Person, where “control” means the possession, directly or indirectly, of the power to direct the management and policies of a Person whether through the ownership of voting securities, contract or otherwise.

     Section 22. Governing Law; Arbitration.

     (a) The corporate law of the State of Delaware shall govern all issues and questions concerning the relative rights of the Company and its stockholders. All other issues and questions concerning the construction, validity, interpretation and enforceability of this Agreement and the exhibits and schedules hereto shall be governed by, and construed in accordance with, the laws of the State of Delaware, without giving effect to any choice of law or conflict of law rules or provisions (whether of the State of Delaware or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Delaware. In furtherance of the foregoing, the internal law of the State of Delaware shall control the interpretation and construction of this Agreement (and all schedules and exhibits hereto), even though under that jurisdiction’s choice of law or conflict of law analysis, the substantive law of some other jurisdiction would ordinarily apply.

     (b) The parties agree that subject to requirements of Section 2(d) and except for (A) determination of Fair Market Value, (B) the specific remedy set forth in Section 10(a) relating to disputed Board action, and (C) actions seeking injunctive relief, all disputes arising under or related to this Agreement shall be resolved solely by binding arbitration and that the dispute resolution provisions of this agreement are exclusive. An arbitration may be initiated by any Clarity Party or Hitachi (or its successors or permitted assigns) on behalf of itself and its Affiliates by written notice to the other, which notice shall specify in reasonable detail the dispute being submitted to arbitration. The arbitration provided for in this agreement shall take place (i) if the issues of such arbitration primarily relate to the U.S. operations of the Company, in New York, New York, or such other city as Clarity reasonably determines would minimize the disruption to the Company’s operations caused by the arbitration and the Company’s expenses related to such arbitration, (ii) if the issues of such arbitration primarily relate to the Japanese operations of the Company, in Tokyo, Japan, or (iii) if the issues do not primarily relate to the U.S. or Japanese operations of the Company, in the city in which the Company has its headquarters (or, if such headquarters are not located in a city, the city closest thereto), or such

other place as determined by the arbitrators to minimize the disruption to the Company’s operations caused by the arbitration and the Company’s expenses related to such arbitration. The arbitration proceedings shall be in English and in accordance with the rules of the American Arbitration Association. The arbitration shall be held before and decided by a panel of three neutral arbitrators, with Hitachi and Clarity each selecting one arbitrator and the two selected arbitrators choosing a third, neutral arbitrator. In no event shall any party be entitled to receive, and the arbitrators shall not be empowered to award, punitive or exemplary damages. In addition, the arbitrators shall not have the authority to hear or determine any claim seeking primarily injunctive relief, or to issue any remedy in the nature of injunctive relief. The decision of the arbitrators may be confirmed in a court if the losing party does not act in accordance with the arbitral award within 45 days of the date of such award, and shall be final and not be appealable for any reason.

     (c) Unless otherwise determined by the arbitrators, the fees and expenses of the parties incurred in connection with, or defending, the arbitration (including, without limitation, all attorneys’ fees and costs), the arbitrators and any other third party costs associated with the arbitration (e.g., court reporters, etc.) shall be borne in full by the party that does not prevail in the arbitration.

     Section 23. Business Days. If any time period for giving notice or taking action hereunder expires on a day which is a Saturday, Sunday or legal holiday in either New York, New York or Tokyo, Japan, the time period shall automatically be extended to the business day immediately following such Saturday, Sunday or legal holiday.

     Section 24. Descriptive Headings. The descriptive headings of this Agreement are inserted for convenience only and do not constitute a part of this Agreement.

     Section 25. Confidentiality.

     (a) With respect to any information furnished to a Stockholder pursuant to this Agreement which the Stockholder reasonably understands to be proprietary or confidential in nature, the Stockholder shall maintain the confidentiality of all such information in accordance with such Stockholder’s policies for the protection of its own nonpublic information.

     (b) The limitations set forth in this Section 25 shall not apply with respect to the disclosure of any information (A) to such Stockholder’s employees, auditors, counsel or other professional advisors, to Affiliates or to another Stockholder, if the disclosing Stockholder or any of its Affiliates, 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 25 to the extent as such Stockholder, (B) as has become or previously was generally available to the public other than by reason of a breach of this Section 25 by such Stockholder or has become available to such Stockholder on a non-confidential basis, (C) 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 such

Stockholder (it being understood that, to the extent practicable, such Stockholder shall provide the Company prompt notice to any such event and cooperate in good faith to enable the Company to participate to protect its interest in such confidential information), (D) as may be required or appropriate in response to any summons or subpoena or in connection with any litigation, (E) in order to comply with any law, order, regulation or ruling applicable to such Stockholder, and (F) to any prospective transferee in connection with any contemplated sale or transfer of any of Company’s securities held by such Stockholder; provided that such prospective transferee agrees to be bound by the provisions of this Section 25 to the same extent as such Stockholder.

     (c) Notwithstanding the foregoing, the parties to this Agreement acknowledge that they are subject to nondisclosure obligations under the other Collateral Agreements, and agree that no party may obtain or disclose any information hereunder in order to avoid such party’s obligations under such other Collateral Agreements.

     Section 26. Delivery by Facsimile. This Agreement, the agreements referred to herein, and each other agreement or instrument entered into in connection herewith or therewith or contemplated hereby or thereby, 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 or thereto shall re-execute original forms thereof and deliver them to all other parties. No party hereto or to any such agreement or instrument shall raise the use of a facsimile machine to deliver a signature or the fact that any signature or agreement or instrument was transmitted or communicated through the use of a facsimile machine as a defense to the enforceability of a contract and each such party forever waives any such defense.

     Section 27. Payments in U.S. Dollars. All payments to be made by the parties pursuant to the terms of this Agreement shall be in United States dollars.

     Section 28. Submission to Jurisdiction; Waivers. With respect to disputes not required to be submitted to arbitration hereunder (including actions for injunctive relief or for confirmation or enforcement of an arbitration award), each party to this Agreement hereby irrevocably and unconditionally:

     (a) submits for itself and its property in any legal action or proceeding relating to this Agreement, or for recognition and enforcement of any judgment in respect thereof, to the non-exclusive general jurisdiction of the courts of the State of Delaware, the courts of the United States of America situated in Delaware and appellate courts from any thereof;

     (b) 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;

     (c) 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 law; and

     (d) 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 sue in any other jurisdiction.

FIRST AMENDMENT TO STOCKHOLDERS’ AGREEMENT

     THIS FIRST AMENDMENT TO STOCKHOLDERS’ AGREEMENT (this “Amendment”) is entered into as of October 1, 2002, by and among OpNext, Inc., a Delaware corporation (the “Company”), Hitachi Ltd., a corporation organized under the laws of Japan (“Hitachi”), Clarity Partners, L.P., a Delaware limited partnership (“Clarity”), Clarity OpNext Holdings I, LLC,  a Delaware limited liability company (“Clarity Holdings I”) and Clarity OpNext Holdings II LLC, a Delaware limited liability company (“Clarity Holdings II”).

W I T N E S S E T H:

     WHEREAS, the parties hereto have entered into that certain Stockholders’ Agreement, dated as of July 31, 2001 (as amended, supplemented or otherwise modified prior to the date hereof, the “Existing Agreement”; and as amended by this Amendment and as the same may be further amended, supplemented or otherwise modified from time to time, the “Agreement”);

     WHEREAS, capitalized terms used herein and not otherwise defined herein shall have the meaning ascribed to them in the Existing Agreement;

     WHEREAS, the Company and Hitachi have entered into that certain Stock Purchase Agreement, dated as of the date hereof (as amended, supplemented or otherwise modified from time to time, the “Opto-Device Stock Purchase Agreement”), pursuant to which OpNext has agreed, subject to the terms and conditions stated therein, to purchase all of the outstanding capital stock of Opto Device, Ltd., a corporation organized under the laws of Japan (“Opto-Device”); and

     WHEREAS, in connection with the Company’s purchase of the capital stock of Opto-Device and the other transactions contemplated by the Opto-Device Stock Purchase Agreement, the parties wish to amend certain terms of the Existing Agreement as set forth herein;

     NOW, THEREFORE, in consideration of the mutual promises contained herein and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereby agree to amend the Existing Agreement as follows:

     Section 1. Defined Terms. Capitalized terms used herein and not otherwise defined herein shall have the meaning ascribed to them in the Existing Agreement.

     Section 2. Amendment to Section 12 of the Existing Agreement. Section 12 of the Existing Agreement is hereby amended by deleting said Section in its entirety and by substituting, in lieu thereof, the following:

     “Section 12. Nonsolicitation and Noncompetition.

     (a) During the period beginning on the Closing and ending at the earlier of (i) one year after the date of an Initial Public Offering and (ii) such time as Hitachi and its Permitted Transferees no longer hold at least a majority of the Voting Securities of the Company

(the “Non-Competition Period”), Hitachi shall not, and shall cause its Subsidiaries to not, participate or engage in or otherwise invest in, directly or indirectly, any area of the world, the business of designing, developing, manufacturing (or having manufactured), marketing, distributing or selling the following fiber optical products, in each case which are dedicated to use in or intended to be used in telecommunications applications (“Restricted Products”): transmitters, receivers, transceivers, laser diodes, laser diode modules, photo diode modules, parallel optical interconnectors, lasers, photodiodes, modulators, amplifiers modules, optical switches, infra-red emitting diodes and optical wave guides.

     (b) During the Non-Competition Period, Hitachi shall not, and shall cause its Wholly-Owned Subsidiaries to not, participate or engage in or otherwise invest in, directly or indirectly, any area of the world, the business of designing, developing, manufacturing (or having manufactured), marketing, distributing or selling Restricted Products, including licensing its Intellectual Property related to Restricted Products to third parties except (i) as part of a global cross license and (ii) any other form of agreement so long as such agreement does not adversely affect the ongoing business of the Company, other than on behalf of the Company and its Subsidiaries as a sales agent or distributor.

     (c) Notwithstanding anything in Section 12(a) and Section 12(b) to the contrary:

     (i) Intentionally omitted;

     (ii) Intentionally omitted;

     (iii) The provisions of this Section 12 shall not restrict in any manner the activities of (A) Hitachi Cable, Ltd. and its subsidiaries, (B) any other present entities which currently have publicly traded equity securities outstanding and which are listed on Schedule 12(b)(iii) including their subsidiaries, (C) any future entities which may issue or have publicly traded equity securities outstanding and which are not wholly owned by Hitachi, and (D) any present or future joint ventures to which Hitachi or any of its entities previously described in this clause (iii) is a party; and

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

     (d) The parties hereto recognize that the laws and public policies of various jurisdictions may differ as to the validity and enforceability of covenants similar to those set forth in this Section 12. Hitachi acknowledges that the provisions of this Section 12 are reasonable and necessary to protect and preserve the business of the Company, that the Clarity Parties entered into this Agreement and the Stock Purchase Agreement on the basis of this provision and that the Company and the Clarity Parties would be irreparably damaged if Hitachi were to breach the covenants set forth in this Section 12. It is the intention of the parties that the provisions of this Section 12 be enforced to the fullest extent permissible under the laws and policies of each jurisdiction in which enforcement may be sought, and that the unenforceability (or the modification to conform to such laws or policies) of any provisions of this Section 12 shall not render unenforceable, or impair, the remainder of the provisions of this Section 12. Accordingly, if any provision of this Section 12 shall be determined to be invalid or unenforceable, such invalidity or unenforceability shall be deemed to apply only with respect to the operation of such provision in the particular jurisdiction in which such determination is made and not with respect to any other provision or jurisdiction.

     (e) The parties hereto acknowledge and agree that any remedy at law for any breach of the provisions of this Section 12 would be inadequate, and Hitachi hereby consents to the granting by any court of an injunction or other equitable relief, without the necessity of actual monetary loss being proved, in order that the breach or threatened breach of such provisions may be effectively restrained.

     (f) Hitachi acknowledges that its current customary practice is to request the approval of the general manager of any division or Subsidiary of Hitachi prior to soliciting or hiring any employee of such division or Subsidiary, and Hitachi will use its best efforts to continue this customary practice with respect to the Business on and after the Closing Date.

     (g) The parties acknowledge that nothing in this Section 12 is intended to restrict Hitachi or any of its Affiliates from continuing or seeking to do business with any Person who is a customer or supplier of the Company, subject to compliance the noncompetition provisions of this Section 12.”

     Section 3. References to Agreement. All references in the Agreement to “this Agreement”, “hereunder”, “hereof”, “herein” or words of like import shall mean and be a reference to the Agreement as amended and modified hereby.

     Section 4. Effectiveness. This Amendment shall become effective as of the date first written above.

     Section 5. Continuing Validity of Existing Agreements. (a) Except as specifically amended above, the Existing Agreement shall remain in full force and effect and is hereby ratified and confirmed.

     (b) The parties agree that the SIC Letter Agreement is superceded in all respects by this Amendment.

     Section 6. Governing Law. This Amendment shall be governed by the laws of the State of Delaware.

     Section 7. Counterparts. This Amendment may be executed simultaneously in any number of counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

     Section 8. April 18^th Side Letter. This Amendment supercedes, in its entirety, the SIC Letter Agreement, and such SIC Letter Agreement shall no longer be of any force and effect.

2005 AMENDMENT

TO

THE STOCKHOLDERS AGREEMENT BETWEEN OPNEXT, INC.

AND EACH OF HITACHI, LTD., CLARITY PARTNERS, L.P., CLARITY OPNEXT

HOLDINGS I, LLC AND CLARITY OPNEXT HOLDINGS II, LLC

     THIS SECOND AMENDMENT (the “Amendment”) to the Stockholders Agreement is made as of June 30, 2005, by and among OpNext, Inc., a corporation organized and existing under the laws of the state of Delaware (the “Company”), Hitachi, Ltd., a corporation organized under the laws of Japan (“Hitachi”), Clarity Partners, L.P., a Delaware limited partnership (“Clarity”), Clarity OpNext Holdings I, LLC, a Delaware limited liability company (“Holdings I”) and Clarity OpNext Holdings II, LLC, a Delaware limited liability company (“Holdings II,” and together with Clarity and Holdings I, the “Clarity Parties,” and each, a “Clarity Party”). Capitalized terms used but not otherwise defined herein will have the meanings set forth in the Stockholders Agreement.

     1. The Company, Hitachi and the Clarity Parties are parties to a Stockholders Agreement, dated as of July 31, 2001 (as amended, supplemented or otherwise modified prior to the date hereof, the “Stockholders Agreement”).

     2. The Company, Hitachi and the Clarity Parties now wish to amend the Stockholders Agreement pursuant to Section 15 thereof.

     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 hereto agree as follows:

     A. Section 10(a) of the Stockholders Agreement is hereby amended in its entirety to read as follows:

In the event that, on or after the sixth anniversary of the Closing, a proposed action of the Company or any Subsidiary that is subject to Section 2(b) is submitted to the Board for consideration and such action is both supported by the Hitachi Directors and rejected by the Clarity director at two consecutive regularly scheduled Board meetings and, as a result, the Board has affirmatively rejected the proposed action, then the Company shall have the right to purchase all (but not less than all) of the Stockholder Shares held by the Clarity Parties by delivering written notice to the Clarity Parties within 60 days of the date of such final rejection (the “Call Date”); provided, however, Hitachi shall not be entitled to exercise this right if such rejected action required any Clarity Party to extend capital to, or otherwise incur liabilities (contingent or otherwise) on behalf or for the benefit of the Company or any of its Subsidiaries, or to grant any liens on any of the property of any Clarity Party.

     B. Section 11(b) of the Stockholders Agreement is hereby amended in its entirety to read as follows:

     At any time beginning on the third anniversary of the Closing Date and ending on July 31, 2007, Clarity may demand a determination of the Fair Market Value (a “Determination Notice”) for purposes of

this Section 1.1. After the receipt of any Determination Notice, the Company and Clarity shall promptly determine the Fair Market Value hereunder and within 30 days after the Fair Market Value has been determined, Clarity may demand purchase of the Stockholder Shares held by the Clarity Parties (the “Put Notice”), in whole or in part, at an amount equal to the Put Price by notice to the Company; provided that the Clarity Parties shall be entitled to no more than one demand pursuant to this Section 11. The Put Price shall be payable by the Company in U.S. dollars to the Clarity Parties on the twentieth Business Day after receipt of the Put Notice by wire transfer of immediately available funds to the account(s) designated by the Clarity Parties upon surrender of certificates representing the Stockholder Shares that are the subject of such Put Notice.

     C. This Amendment may be executed in one or more counterparts, any one of which may bear the signature of fewer than all of the signatories hereto, but all of which taken together shall constitute one agreement.

     D. Except as expressly set forth herein, the terms and provisions of the Stockholders Agreement remain in full force and effect and the parties hereby ratify and affirm the Stockholders Agreement.

     E. The terms and provisions of the Stockholders Agreement shall govern this Amendment.

     IN WITNESS WHEREOF, the parties hereto have caused this Amendment to Stockholders Agreement to be duly executed and delivered as of the date first above written.
