(n) Intellectual Property.

(i)The Company or its Subsidiaries owns all trade and service marks, trade and service mark applications and registrations, trade names, trade secrets, copyrights, and other similar intellectual property rights and similar proprietary rights (collectively, “Proprietary Rights”) and all patents and patent applications (collectively, with Proprietary Rights, “Intellectual Property Rights”) that the Company has represented to Purchaser in writing that the Company or its Subsidiaries own (“Company Owned Intellectual Property Rights”). The Company owns, possesses, licenses or has other rights to use all Proprietary Rights and, to the Company’s knowledge, all patents that are necessary or material for use in connection with the manufacture, use, sale, and distribution of the products, services and conduct of the Company’s or any of its Material Subsidiaries’ businesses as has been conducted prior to the date of this Agreement (collectively, together with all Company Owned Intellectual Property Rights, the “Company Intellectual Property Rights”).

Neither the Company nor any of its Material Subsidiaries has received a notice (written or otherwise) that any Company Products or Business (including the manufacture, use, sale, and distribution of such products and services) infringes, misappropriates or otherwise violates any Intellectual Property Right of any Person, nor does the Company or any of its Subsidiaries know of any basis for such a claim that would result in a Material Adverse Effect.

To the knowledge of the Company, there has not been any disclosure of any Company Intellectual Property Rights constituting a material trade secret of the Company or any of its Subsidiaries in a manner that has resulted or is likely to result in the loss of trade secret in and to such information. There are no material outstanding options, licenses, claims, encumbrances or shared ownership interests of any kind relating to the Company Owned Intellectual Property Rights. As of the date of this Agreement, the Company or any of its Subsidiaries is not bound by or a party to any license agreements pursuant to which third-party Intellectual Property Rights that are embodied in or incorporated into Company Products or Business are licensed to the Company (excluding, without limitation, any software licenses for software not incorporated into Company’s products or otherwise giving rise to royalties based on sale or distribution of Company’s products where such software is generally available on standard terms). Each current and former employee or contractor of the Company or its Material Subsidiaries that has materially contributed to the development of any Company Owned Intellectual Property Right or Company Products or Business has executed and delivered to the Company a valid and enforceable agreement that (i) assigns to the Company or Subsidiaries all right, title and interest in and to any such Intellectual Property Rights and (ii) requires confidential treatment for the trade secrets, know-how and other confidential Intellectual Property Rights of the Company. To the knowledge of the Company, no current or former employee, officer, consultant or contractor of the Company is in default or breach of any term of any employment, consulting or contractor agreement, non-disclosure agreement, assignment agreement, or similar agreement where such default or breach would result in the Company Products or Business infringing, misappropriating or otherwise violating any Intellectual Property Right of any Person. To the knowledge of the Company, no present or former employee, officer, consultant or contractor of the Company has any ownership, license or other right, title or interest, directly or indirectly, in whole or in part, in any Company Intellectual Property Rights.

All applications for registrations of Company Registered Intellectual Property Rights filed with the United States or foreign authorities (as applicable) have been prosecuted in compliance with all applicable rules, policies, and procedures of such authorities (as applicable). “Registered Intellectual Property Rights” shall mean all United States, international and foreign Intellectual Property Rights that are registered, filed or issued under the authority of any United States, international or foreign government, including all patents, registered copyrights, registered mask works, and registered trademarks, and any applications for the foregoing. “Company Registered Intellectual Property Rights” means any and all Company Owned Intellectual Property Rights that are Registered Intellectual Property Rights. “Issued” means (i) granted or issued for any patents, (ii) registered for any copyrights, and (iii) registered for any trade and service marks.

In connection with any transfer of the Shares other than (i) pursuant to an effective registration statement, (ii) to the Company, (iii) to an Affiliate of a Purchaser, or (iv) pursuant to Rule 144 (provided that the Purchaser provides the Company with reasonable assurances (in the form of seller and broker representation letters) that the securities may be sold pursuant to such rule), the Company may require an opinion of counsel reasonably acceptable to the Company, the form and substance of which opinion shall be reasonably satisfactory to the Company, to the effect that such transfer does not require registration of such transferred Shares under the Securities Act. As a condition of any such transfer, any such transferee shall agree in writing to be bound by the terms of Article 4 of this Agreement and shall have the rights of a Purchaser under this Agreement and the Rights Agreement.

(b) Legends. The records of the Transfer Agent shall reflect that the Shares shall be subject to any legend or restrictive notation as required by the “blue sky” laws of any state and a restrictive legend in substantially the following form until such time as they are not required under Section 4.1(c) (and a stock transfer order may be placed against transfer of the Shares in violation of this Agreement):

THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR APPLICABLE STATE SECURITIES LAWS. THE SECURITIES MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED (I) IN THE ABSENCE OF (A) AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT OR (B) AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS OR BLUE SKY LAWS AS EVIDENCED BY A LEGAL OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE COMPANY AND ITS TRANSFER AGENT OR (II) UNLESS SOLD PURSUANT TO RULE 144 UNDER SAID ACT. NOTWITHSTANDING THE FOREGOING, THE SECURITIES MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN OR FINANCING ARRANGEMENT SECURED BY THE SECURITIES.

In addition, if the Purchaser is an Affiliate of the Company, the Shares issued to the Purchaser shall be subject to a customary “affiliates” notation and legend in substantially the following form for so long as the Purchaser is an Affiliate of the Company:

THE SHARES REPRESENTED BY THIS CERTIFICATE ARE HELD BY A PERSON WHO MAY BE DEEMED TO BE AN AFFILIATE OF THE ISSUER FOR PURPOSES OF RULE 144 PROMULGATED UNDER THE SECURITIES ACT OF 1933, AS AMENDED.

By signing this Agreement, and for purposes of acknowledging the restrictions on the uncertificated Shares, the Purchaser acknowledges that the Company has provided it with written notice of the information and legends set forth in this Section 4.1 that would be required to be set forth or stated on stock certificates for the Shares.

(c) Removal of Legends. The notation(s) and legend(s) set forth in Section 4.1(b) above shall be removed from the Transfer Agent’s records for the Shares and the Company shall instruct the Transfer Agent to issue to such holder by electronic delivery at the applicable balance account at the Depository Trust Company (“DTC”), if (i) such Shares are registered for resale under the Securities Act (provided that, if the Purchaser is selling pursuant to the effective registration statement registering the Shares for resale, the Purchaser agrees to only sell such Shares during such time that such registration statement is effective and not withdrawn or suspended, and only as permitted by such registration statement), (ii) such Shares are sold or transferred pursuant to Rule 144, or (iii) such Shares are eligible for sale under Rule 144, without the requirement for the Company to be in compliance with the current public information required under Rule 144 as to such securities and without volume or manner-of-sale restrictions. Following the earlier of (i) the Effective Date or (ii) Rule 144 becoming available for the resale of Shares, without the requirement for the Company to be in compliance with the current public information required under Rule 144 as to such securities and without volume or manner-of-sale restrictions, the Company shall instruct the Transfer Agent to remove the notations and restrictive legend(s) set forth in Section 4.1(b) from the applicable Shares. Following such time as a restrictive notation or legend is no longer required for certain Shares, the Company will, no later than three (3) Trading Days following the written request by a Purchaser to the Company, instruct the Transfer Agent to remove the notations and restrictive legend(s) set forth in Section 4.1(b) from the Purchaser’s applicable Shares.

(d) Irrevocable Transfer Agent Instructions. The Company shall issue irrevocable instructions to its Transfer Agent, and any subsequent transfer agent, in substantially the form ofExhibit C attached hereto (the “Irrevocable Transfer Agent Instructions”).

4.2 Transactions in Company Securities. The Purchaser covenants that neither it nor any Person acting on its behalf or pursuant to any understanding with it will engage in any transactions in the Company’s securities (including, without limitation, any Short Sales involving the Company’s securities) during the period from the date hereof until the earlier of such time as (i) the transactions contemplated by this Agreement are first publicly announced or (ii) this Agreement is terminated in full pursuant to Section 6.16. The Purchaser covenants that until such time as the transactions contemplated by this Agreement are publicly disclosed by the Company, the Purchaser will maintain the confidentiality of the existence and terms of this transaction and the information included in the Transaction Documents and Disclosure Letter. The Purchaser understands and acknowledges that the Commission currently takes the position that covering a short position established prior to effectiveness of a resale registration statement with shares included in such registration statement would be a violation of Section 5 of the Securities Act, as set forth in the Compliance and Disclosure Interpretation of the staff of the Division of Corporation Finance (with respect to Securities Act Sections) regarding short selling.

4.3 Form D. The Company agrees to timely file a Form D with respect to the Shares as required under Regulation D and to provide a copy thereof to the Purchaser (provided that the posting of the Form D on the Commission’s EDGAR system shall be deemed delivery of the Form D for purposes of this Agreement).

4.4 Use of Proceeds. The Company agrees to use the proceeds of the offering as set forth in Section 6(e) of the Rights Agreement.

4.5 Subsequent Equity Sales. The Company shall not, and shall use its commercially reasonable efforts to ensure that no Affiliate of the Company shall, sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in Section 2 of the Securities Act) that will be integrated with the offer or sale of the Shares in a manner that would require the registration under the Securities Act of the sale of the Shares to the Purchaser, or that will be integrated with the offer or sale of the Shares for purposes of the rules and regulations of the Principal Trading Market such that it would require stockholder approval prior to the closing of such other transaction unless stockholder approval is obtained before the closing of such subsequent transaction.

4.6 Listing. The Company shall promptly take any action required to maintain the listing of all of the Shares, once they have been issued, upon the Principal Trading Market upon which shares of Common Stock are listed (subject to official notice of issuance) and shall maintain, so long as any other shares of Common Stock shall be so listed, such listing of all Shares from time to time issuable under the terms of the Transaction Agreements. Until such time as the Company’s shares of Common Stock are deregistered under the Exchange Act pursuant to a stockholder-approved transaction providing for such deregistration, the Company shall take all actions within its control to comply with the reporting requirements of the Exchange Act and the Principal Trading Market on which the Common Stock is listed. The Company shall not take any action which would be reasonably expected to result in the delisting or suspension of the Common Stock on the Principal Trading Market, except in connection with a stockholder-approved transaction providing for the deregistration of the Common Stock under the Exchange Act.

Open Joint Stock Company “RUSNANO”

Prospect 60-letiya Oktyabrya 10a

117036 Moscow

Russian Federation

Re: NeoPhotonics Corporation

Dear Ladies and Gentlemen:

We have acted as counsel for NeoPhotonics Corporation, a Delaware corporation (the “Company”), in connection with the issuance and sale of 4,972,905 shares of the Company’s Common Stock (“Shares”), to the Purchaser under the Share Purchase Agreement dated as of April 27, 2012 (the “Purchase Agreement”). We are rendering this opinion pursuant to Section 2.2(vii) of the Purchase Agreement. Except as otherwise defined herein, capitalized terms used but not defined herein have the respective meanings given to them in the Purchase Agreement.

In connection with this opinion, we have examined and relied upon the representations and warranties as to factual matters contained in and made pursuant to the Purchase Agreement by the various parties and originals or copies certified to our satisfaction, of such records, documents, certificates, opinions, memoranda and other instruments as in our judgment are necessary or appropriate to enable us to render the opinion expressed below.

As to certain factual matters, we have relied upon certificates of officers of the Company and have not sought to independently verify such matters. Where we render an opinion “to our knowledge” or concerning an item “known to us” or our opinion otherwise refers to our knowledge, it is based solely upon (i) an inquiry of attorneys within this firm who have represented the Company in this transaction, (ii) receipt of a certificate executed by an officer of the Company covering such matters, and (iii) such other investigation, if any, that we specifically set forth herein.

In rendering this opinion, we have assumed: the authenticity of all documents submitted to us as originals; the conformity to originals of all documents submitted to us as copies; the accuracy, completeness and authenticity of certificates of public officials; the due authorization, execution and delivery of all documents (except the due authorization, execution and delivery by the Company of the Purchase Agreement and the Rights Agreement (together, the “Financing Agreements”)), where authorization, execution and delivery are prerequisites to the effectiveness of such documents; and the genuineness and authenticity of all signatures on original documents (except the signatures on behalf of the Company on the Financing Agreements). We have also assumed: that all individuals executing and delivering documents had the legal capacity to so execute and deliver; that the Financing Agreements are obligations binding upon the parties thereto other than the Company; that the parties to the Financing Agreements other than the Company have filed any required California franchise or income tax returns and have paid any required California franchise or income taxes; and that there are no extrinsic agreements or understandings among the parties to the Financing Agreements or to the Material Agreements (as defined below) that would modify or interpret the terms of any such Agreements or the respective rights or obligations of the parties thereunder.

Our opinion is expressed only with respect to the federal laws of the United States of America and the laws of the State of New York (except no opinion with respect to the laws of the State of New York is expressed as to the Material Agreements (as defined below), the State of California and the General Corporation Law of the State of Delaware. We express no opinion as to whether the laws of any particular jurisdiction apply, and no opinion to the extent that the laws of any jurisdiction other than those identified above are applicable to the subject matter hereof.

We are not rendering any opinion as to any statute, rule, regulation, ordinance, decree or decisional law relating to antitrust, banking, land use, environmental, pension, employee benefit, tax, fraudulent conveyance, usury, laws governing the legality of investments for regulated entities, regulations T, U or X of the Board of Governors of the Federal Reserve System or local law. Furthermore, we express no opinion with respect to compliance with antifraud laws, rules or regulations relating to securities or the offer and sale thereof; compliance with fiduciary duties by the Company’s Board of Directors or stockholders; compliance with safe harbors for disinterested Board of Director or shareholder approvals; compliance with state securities or blue sky laws except as specifically set forth below; compliance with laws that place limitations on corporate distributions; or the enforceability of provisions in the Financing Agreements concerning the voting of the Company’s capital stock (other than solely administrative obligations of the Company).

With regard to our opinion in paragraphs 1 and 3 below with respect to the good standing of the Company and the Company’s qualification to do business as a foreign corporation, we have relied solely upon certificates of the Secretaries of State of the indicated jurisdictions as of a recent date.

With regard to our opinion in paragraphs 6 and 7 below concerning rights of first refusal, rights of first offer or similar rights, or defaults under and any material breaches of any agreement identified on Schedule A hereto (the “Material Agreements”), we have relied solely upon (i) inquiries of officers of the Company, and (ii) an examination of the Material Agreements in the form provided to us by the Company. We have made no further investigation. Further, with regard to our opinion in paragraph 7 below concerning Material Agreements, we express no opinion as to (i) financial covenants or similar provisions therein requiring financial calculations or determinations to ascertain compliance, (ii) provisions therein relating to the occurrence of a “material adverse event” or words of similar import, or (iii) any statement or writing that may constitute parol evidence bearing on interpretation or construction. To the extent that any other laws govern any of the Material Agreements, we assume that the Material Agreements would be interpreted in accordance with their plain meaning.

With regard to our opinion in paragraph 8 below with respect to pending or overtly threatened litigation, we have made an inquiry of the attorneys within this firm who have represented the Company in this transaction, examined and relied upon a certificate executed by an officer of the Company covering such matters, and checked the records of this firm to ascertain that we are not acting as counsel of record for the Company in any such matter. We have made no further investigation.

With regard to our opinion in paragraph 10 concerning exemption from registration, our opinion is expressed only with respect to the offer and sale of the Shares without regard to any offers or sales of other securities occurring prior to or subsequent to the date hereof.

With regard to our opinion in paragraph 11 below, we have based our opinion on a certificate of an officer of the Company as to compliance with each of the requirements of Section 3(a)(1) of the Investment Company Act of 1940, as amended (the “1940 Act”). We have conducted no further investigation.

On the basis of the foregoing, in reliance thereon and with the foregoing qualifications, we are of the opinion that:

8.	The Company has been duly incorporated and is a validly existing corporation in good standing under the laws of the State of Delaware.

9.	The Company has the requisite corporate power to own its property and assets and to conduct its business as it is currently being conducted.

10.

The Company is duly qualified to do business as a foreign corporation and is in good standing under the laws of California.

11.

The Company has the requisite corporate power to execute, deliver and perform its obligations under the Financing Agreements.

12.

Each of the Financing Agreements has been duly and validly authorized, executed and delivered by the Company and each such agreement constitutes a valid and binding agreement of the Company enforceable against the Company in accordance with its respective terms, except as rights to indemnity and contribution under section 6.2 of the Purchase Agreement and section 5 of the Rights Agreement may be limited by applicable laws and except as enforcement may be limited by applicable bankruptcy, insolvency, reorganization, arrangement, moratorium or other similar laws affecting creditors’ rights, and subject to general equity principles and to limitations on availability of equitable relief, including specific performance.

13.

The Shares have been duly authorized, and upon issuance and delivery against payment therefor in accordance with the terms of the Purchase Agreement, the Shares will be validly issued, outstanding, fully paid and nonassessable and will have been acquired free of any preemptive rights, rights of first refusal, rights of first offer or similar rights contained in the Company’s Certificate of Incorporation or Bylaws or any in Material Agreement that have not been waived.

14.

The execution and delivery of the Financing Agreements by the Company and the issuance of the Shares pursuant thereto do not violate any provision of the Company’s Certificate of Incorporation or Bylaws, and do not constitute a default under or a material breach of any Material Agreement, and do not violate (a) any governmental statute, rule or regulation which in our experience is typically applicable to transactions of the nature contemplated by the Financing Agreements or (b) any order, writ, judgment, injunction, decree, determination or award which has been entered against the Company and of which we are aware, in the case of (a) and (b) to the extent the violation of which would materially and adversely affect the Company and its subsidiaries, taken as a whole.

15.

To our knowledge, except as set forth in the SEC Reports, there is no action, proceeding or investigation pending or overtly threatened against the Company before any court or administrative agency that questions the validity of the Financing Agreements or that could reasonably be expected to result, either individually or in the aggregate, in a material adverse effect on the Company and its subsidiaries, taken as a whole, that has not been disclosed in the Disclosure Letter to the Purchase Agreement.

16.

All consents, approvals, authorizations, or orders of, and filings, registrations, and qualifications with any U.S. Federal or California regulatory authority or governmental body required for the issuance of the Shares, have been made or obtained, except for the filing of a Form D pursuant to Securities and Exchange Commission Regulation D.

17.

The offer and sale of the Shares are exempt from the registration requirements of the Securities Act of 1933, as amended, subject to the timely filing of a Form D pursuant to Securities and Exchange Commission Regulation D.

18.

The Company is not, and, after giving effect to the offering and sale of the Shares and the application of the proceeds thereof, will not be, required to register as an “investment company” as such term is defined in the 1940 Act.

This opinion is intended solely for your benefit and is not to be made available to or be relied upon by any other person, firm, or entity without our prior written consent.

Very truly yours,


COOLEY LLP
