Person, (i) the present fair saleable value of such Person’s assets is less than the amount required to pay such Person’s total indebtedness, (ii) such Person is unable to pay its debts and liabilities, subordinated, contingent
or otherwise, as such debts and liabilities become absolute and matured, (iii) such Person intends to incur or believes that it will incur debts that would be beyond its ability to pay as such debts mature or (iv) such Person has
unreasonably small capital with which to conduct the business in which it is engaged as such business is now conducted and is currently proposed to be conducted.

Documents or the issuance of the Shares, (ii) involves a claim of material violation of or material liability under any federal, state, local or foreign laws governing the Company’s or its Material Subsidiaries’ operations, or

the Company under the Exchange Act or the Securities Act. 
 (m) Title to Assets. The Company and its Material
Subsidiaries have good and valid title (in the case of real property) to, or have valid rights to lease or otherwise use, all items of real and personal property and assets that are material to the respective businesses of the Company and its
Material Subsidiaries, in each case free and clear of all liens, encumbrances, claims and defects and imperfections of title except those that (i) do not materially interfere with the use made and proposed to be made of such property by the
Company and its Material Subsidiaries, or (ii) could not reasonably be expected, individually or in the aggregate, to have a Material Adverse Effect. 
 (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”). The Company owns all Company Owned Intellectual Property Rights free and clear of any Liens
(other than non-exclusive licenses granted in the ordinary course of business). No product or service of the Company or any of its Material Subsidiaries nor the business of the Company nor of any of its Material Subsidiaries as has been conducted
prior to the date of this Agreement (collectively “Company Products or Business”) infringes, misappropriates or otherwise violates any Proprietary Rights or, to the Company’s knowledge, any patent of any Person, nor has
the Company otherwise infringed, misappropriated or otherwise violated any Proprietary Rights or, to the Company’s knowledge, any patent of any Person. 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. There is no pending action, suit, proceeding or claim by any Person that any Company Products or Business infringes,
misappropriates or otherwise violates any Intellectual Property Right of another, and, to the knowledge of the Company, there is no such threatened action, suit, proceeding or claim that would have a Material Adverse Effect. To the Company’s
knowledge, there is no existing infringement by another Person of any of the Company Intellectual Property Rights that would or would reasonably be expected to result in a Material Adverse Effect. None of the Company Products or Business, has been
obtained or is being used, sold or distributed by the Company in violation of any contractual obligation binding on the Company or, to the Company’s knowledge, any of its officers, directors or employees or otherwise in violation of the rights
of any Person. 

  
 13 









 (ii) The Company has taken and takes reasonable security measures (including
appropriate use of nondisclosure agreements) to protect the secrecy, confidentiality and value of the Company Intellectual Property Rights that constitute its material trade secrets. 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. 
 (iii) Each of the Issued Company Registered Intellectual Property Rights
(defined below) is valid and subsisting, all necessary registration, maintenance and renewal fees currently due in connection with any Company Registered Intellectual Property Rights (whether Issued or not) have been made and all necessary
documents, recordations and certificates in connection with Company Registered Intellectual Property Rights have been filed with the relevant authorities in the United States or any other jurisdictions for the purposes of prosecuting, perfecting and
maintaining such Company Registered 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. 

  
 14 









 (iv) Neither the execution nor delivery of the Transaction Documents will conflict
with or result in a breach of the terms, conditions or provisions of, or constitute a default under any contract, covenant or instrument relating to, the license or use of any Company Intellectual Property Right or Company Products or Business,
except for such conflicts, defaults and breaches which would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect and which would not result in any product of the Company infringing, misappropriating or
otherwise violating any Intellectual Property Rights of any Person. 
 (o) Private Placement. Assuming the accuracy of
the Purchaser’s representations and warranties set forth in Section 3.2 of this Agreement and the accuracy of the information disclosed in the Accredited Investor Questionnaires, no registration under the Securities Act is required for the
offer and sale of the Shares by the Company to the Purchaser under the Transaction Documents. 
 (p) Registration Rights.
Other than the Purchaser and the parties to the Investors’ Rights Agreement, no Person has any right to cause the Company to effect the registration under the Securities Act of any securities of the Company other than those securities which are
currently registered on an effective registration statement on file with the Commission. Other than the Purchaser, no Person has any right to cause the Company to effect the registration under the Securities Act of any securities of the Company
pursuant to a registration statement filed pursuant to the terms and conditions of the Rights Agreement. Oak Investment Partners IX, Limited Partnership and its Affiliates and Timothy S. Jenks and his Affiliates are the only parties to the
Investors’ Rights Agreement that are currently entitled to registration rights thereunder or that are required to waive the provisions of the Investors’ Rights Agreement specified in the IRA Waiver. 

(q) No Directed Selling Efforts or General Solicitation. Neither the Company, nor any Person acting on behalf of the Company, has
conducted any “general solicitation” or “general advertising” (as those terms are used in Regulation D) in connection with the offer or sale of any of the Shares. 

(r) No Integrated Offering. Assuming the accuracy of the Purchaser’s representations and warranties set forth in
Section 3.2, neither the Company nor any Person acting on its behalf has, directly or indirectly, made any offers or sales of any Company security or solicited any offers to buy any security under circumstances that would (i) eliminate the
availability of the exemption from registration under Regulation D under the Securities Act in connection with the offer and sale by the Company of the Shares as contemplated hereby or (ii) cause the offering of the Shares pursuant to the
Transaction Documents to be integrated with prior offerings by the Company or aggregated with prior offerings by the Company for purposes of any applicable law, regulation or stockholder approval provisions, including, without limitation, under the
rules and regulations of the Principal Trading Market. 
 (s) Listing and Maintenance Requirements. The Company’s
Common Stock is registered pursuant to Section 12(b) of the Exchange Act, and the Company has taken no action 

  
 15 









 
designed to terminate the registration of the Common Stock under the Exchange Act nor has the Company received any notification that the Commission is contemplating terminating such registration.
Except as set forth in the SEC Reports, the Company has not, in the 12 months preceding the date hereof, received written or oral notice from its Principal Trading Market or from the Financial Industry Regulatory Authority to the effect that
the Company is not in compliance with the listing or maintenance requirements of its Principal Trading Market. Except as set forth in the SEC Reports, the Company is in compliance in all material respects with the listing and maintenance
requirements for continued trading of the Common Stock on the Principal Trading Market. The issuance and sale of the Shares under this Agreement does not contravene the rules and regulations of the Principal Trading Market, and no approval of the
stockholders of the Company thereunder is required for the Company to issue and deliver the Shares to the Purchaser. 
 (t)
Investment Company. The Company is not required to be registered as, and is not an Affiliate of, and immediately following the Closing will not be required to register as, an “investment company” within the meaning of the Investment
Company Act of 1940, as amended.

occurred that has not been waived that, with notice or lapse of time or both, would result in a default by the Company or any Material Subsidiary under), nor has the Company or any Material Subsidiary received written notice of a claim that it is in
default under or that it is in violation of, any material indenture, loan or credit agreement or any other material agreement or instrument to which it is a party or by which it or any of its properties is bound (whether or not such default or
violation has been waived), (ii) is in violation of any order of any court, arbitrator or governmental body, or (iii) is or has been in violation of any material statute, rule or regulation of any governmental authority.

promulgated under the Securities Act. 
 (w) Application of Takeover Protections. There is no control share acquisition,
business combination, poison pill (including any distribution under a rights agreement) or other similar anti-takeover provision under the Company’s charter documents or the laws of its state of incorporation that is or could become applicable
to the Purchaser as a result of the Purchaser and the Company fulfilling their obligations or exercising their rights under the Transaction Documents, including, without limitation, as a result of the Company’s issuance of the Shares and the
Purchaser’s ownership of the Shares. 
 (x) Acknowledgment Regarding Purchaser’s Purchase of Securities. Based
upon the assumption that the transactions contemplated by this Agreement are consummated in all material respects in conformity with the Transaction Documents, the Company acknowledges and agrees that the Purchaser is acting solely in the capacity

Documents to which it is a party and otherwise to carry out its obligations hereunder and thereunder. The execution, delivery and performance by the Purchaser of the transactions contemplated by this Agreement have been duly authorized by all
necessary corporate approvals on the part of the Purchaser. Each of this Agreement and the Rights Agreement has been (or upon delivery will have been) duly executed by the Purchaser, and when delivered by the Purchaser in accordance with the terms

(including federal and state securities laws) applicable to the Purchaser, except in the case of clauses (ii) and (iii) above, for such conflicts, defaults, rights or violations which would not, individually or in the aggregate, reasonably
be expected to have a material adverse effect on the ability of the Purchaser to perform its obligations hereunder. 

  
 20 









 (c) Investment Intent. The Purchaser understands that the Shares are “restricted
securities” and have not been registered under the Securities Act, or any applicable state securities law. The Purchaser is acquiring the Shares as principal for its own account and not with a view to, or for distributing or reselling such
Shares or any part thereof in violation of the Securities Act or any applicable state securities laws. The Purchaser does not presently have any agreement, plan or understanding with any Person to distribute or effect any distribution of any of the
Shares (or any securities which are derivatives thereof) to or through any Person; the Purchaser is not a registered broker-dealer under Section 15 of the Exchange Act or an entity engaged in a business that would require it to be so registered
as a broker-dealer. 
 (d) Purchaser Status. At the time the Purchaser was offered the Shares, it was, and at the date
hereof it is, an “accredited investor” as defined in Rule 501(a) under the Securities Act. 
 (e) General
Solicitation. The Purchaser is not purchasing the Shares as a result of any advertisement, article, notice or other communication regarding the Shares published in any newspaper, magazine or similar media or broadcast over television or radio or
presented at any seminar or any other general advertisement. 
 (f) Experience of Purchaser. The Purchaser, either alone
or together with its representatives, has such knowledge, sophistication and experience in business and financial matters so as to be capable of evaluating the merits and risks of the prospective investment in the Shares, and has so evaluated the
merits and risks of such investment. The Purchaser is able to bear the economic risk of an investment in the Shares and, at the present time, is able to afford a complete loss of such investment. 

(g) Access to Information. The Purchaser acknowledges that it has had the opportunity to review the Disclosure Materials and has
been afforded (i) the opportunity to ask such questions as it has deemed necessary of, and to receive answers from, representatives of the Company concerning the terms and conditions of the offering of the Shares and the merits and risks of
investing in the Shares; (ii) access to information about the Company and its respective financial condition, results of operations, business, properties, management and prospects sufficient to enable it to evaluate its investment; and
(iii) the opportunity to obtain such additional information that the Company possesses or can acquire without unreasonable effort or expense that is necessary to make an informed investment decision with respect to the investment. Neither such
inquiries nor any other investigation conducted by or on behalf of the Purchaser or its representatives or counsel shall modify, amend or affect the Purchaser’s right to rely on the truth, accuracy and completeness of the Disclosure Materials
and the Company’s representations and warranties contained in the Transaction Documents. 
 (h) Certain Trading
Activities. Other than with respect to the transactions contemplated herein, since the time that the Purchaser was first contacted by the Company or any other Person regarding the transactions contemplated hereby, neither the Purchaser nor, to
the knowledge of the Purchaser, any Affiliate of the Purchaser which (x) had knowledge of the transactions contemplated hereby, (y) has knowledge or shares discretion relating to the Purchaser’s investments or trading or information
concerning the Purchaser’s investments, including in respect of the Shares, and (z) is subject to the Purchaser’s review or input concerning

such Affiliate’s investments or trading (collectively, “Trading Affiliates”) has directly or indirectly, nor has any Person acting on behalf of or pursuant to
any understanding with the Purchaser or Trading Affiliate, effected or agreed to effect any transactions in the securities of the Company (including, without limitation, any Short Sales involving the Company’s securities). Notwithstanding the
foregoing, in the case of a Purchaser and/or Trading Affiliate that is, individually or collectively, a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of the Purchaser’s or Trading Affiliate’s
assets and the portfolio managers have no direct knowledge of the investment decisions made by the portfolio managers managing other portions of the Purchaser’s or Trading Affiliate’s assets, the representation set forth above shall apply
only with respect to the portion of assets managed by the portfolio manager that have knowledge about the financing transaction contemplated by this Agreement. Other than to other Persons (a) party to this Agreement or (b) advising the
Purchaser in relation to the Transaction Documents and the transactions contemplated herein and therein, the Purchaser has maintained the confidentiality of all disclosures made to it in connection with this transaction (including the existence and
terms of this transaction). 
 (i) Brokers and Finders. No Person will have, as a result of the transactions contemplated
by this Agreement, any valid right, interest or claim against or upon the Company or the Purchaser for any commission, fee or other compensation pursuant to any agreement, arrangement or understanding entered into by or on behalf of the Purchaser.

 (j) Independent Investment Decision. The Purchaser has independently evaluated the merits of its decision to purchase
Shares pursuant to the Transaction Documents, and the Purchaser confirms that it has not relied on the advice of any other Purchaser’s business and/or legal counsel in making such decision. The Purchaser understands that nothing in this
Agreement or any other materials presented by or on behalf of the Company to the Purchaser in connection with the purchase of the Shares constitutes legal, tax or investment advice. The Purchaser has consulted such legal, tax and investment advisors
as it, in its sole discretion, has deemed necessary or appropriate in connection with its purchase of the Shares. 
 (k)
Reliance on Exemptions. The Purchaser understands that the Shares being offered and sold to it in reliance on specific exemptions from the registration requirements of United States federal and state securities laws and that the Company is
relying in part upon the truth and accuracy of, and the Purchaser’s compliance with, the representations, warranties, agreements, acknowledgements and understandings of the Purchaser set forth herein in order to determine the availability of
such exemptions and the eligibility of the Purchaser to acquire the Shares. 
 (l) No Governmental Review. The Purchaser
understands that no United States federal or state agency or any other government or governmental agency has passed on or made any recommendation or endorsement of the Shares or the fairness or suitability of the investment in the Shares nor have
such authorities passed upon or endorsed the merits of the offering of the Shares. 
 (m) Regulation M. The
Purchaser is aware that the anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of Common Stock and other activities with respect to the Common Stock by the Purchaser. 

  
 22 









 (n) Beneficial Ownership. As of the date hereof, the Purchaser does not own any
securities of the Company (individually or together with any other Person with whom the Purchaser has identified itself as part of a “group” in a public filing made with the Commission involving the Company’s securities). The
Purchaser does not presently intend to, alone or together with others, make a public filing with the Commission to disclose that it has (or that it together with such other Persons have) acquired, or obtained the right to acquire, as a result of
such Closing (when added to any other securities of the Company that it or they then own or have the right to acquire), in excess of 19.999% of the outstanding shares of Common Stock or the voting power of the Company on a post-transaction basis
that assumes that the Closing shall have occurred. 
 (o) Residency. The Purchaser’s principal executive offices are
in the jurisdiction set forth immediately below the Purchaser’s name on the applicable signature page attached hereto. 

(p) Accuracy of Accredited Investor Questionnaire. The Accredited Investor Questionnaire delivered by the Purchaser in connection
with this Agreement is complete and accurate in all material respects as of the date of this Agreement and will be correct in all material respects as of the Closing Date and the effective date of the Registration Statement; provided, that the
Purchaser shall be entitled to update such information by providing written notice thereof to the Company. 
 (q) Foreign
Investors. If Purchaser is not a United States person (as defined by Section 7701(a)(30) of the Internal Revenue Code), Purchaser hereby represents that it has satisfied itself as to the full observance of the laws of its jurisdiction in
connection with any invitation to subscribe for the Shares, or any use of this Agreement, including (i) the legal requirements within its jurisdiction for the purchase of the Shares, if applicable, (ii) any foreign exchange restrictions
applicable to such purchase, (iii) any government or other consents that may need to be obtained, and (iv) the income tax and other tax consequences, if any, that may be relevant to the purchase, holding, redemption, sale or transfer of
the Shares. The Company’s offer and sale and Purchaser’s subscription and payment for and continued beneficial ownership of the Shares will not violate any applicable securities or other laws of Purchaser’s jurisdiction. 

(r) Waiver of Immunity. Entry into and performance of the Transaction Documents by Rusnano constitute private and commercial acts.
Neither Rusnano, nor any of its assets, enjoy any right of immunity, including sovereign immunity, from suit or execution in respect of its obligations under the Transaction Documents. Rusnano hereby waives any such right of immunity, including
sovereign immunity, that could otherwise apply to its obligations under the Transaction Documents. 
 The Company and the
Purchaser acknowledge and agree that no party to this Agreement has made or makes any representations or warranties with respect to the transactions contemplated hereby other than those specifically set forth in this Article III and the
Transaction Documents.

 ARTICLE 4 
 OTHER AGREEMENTS OF THE PARTIES 
 4.1 Transfer Restrictions.

 (a) Compliance with Laws. Notwithstanding any other provision of this Article 4 and subject to any restrictions
set forth in the Lock-Up Agreement, the Purchaser covenants that the Shares may be disposed of only pursuant to an effective registration statement under, and in compliance with the requirements of, the Securities Act, or pursuant to an available
exemption from, or in a transaction not subject to, the registration requirements of the Securities Act, and in compliance with any applicable state and federal securities laws. 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. 

  
 24 









 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 of Exhibit 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. 

  
 25 









 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.

Dispute Resolution. 
 (a) The parties will attempt in good faith to resolve any dispute, or disagreement,

“Dispute”) in accordance with this Section 6.9. In the event of a Dispute, then upon the written request of any party, each of the parties will appoint a designated senior business executive whose task will be to meet
for the purpose of endeavoring to resolve the Dispute. If any such Dispute has not been resolved within thirty (30) days after the date of request (the “Initial Resolution Period”) by a party for resolution under this
Section 6.9, it will be submitted for consideration of the Chief Executive Officer of the Company and Oleg V. Kiselev (or his successor), the Deputy Chief Executive Officer of the Purchaser. If such representatives are unable, after a period of
thirty (30) days following the end of the Initial Resolution Period, to resolve the Dispute, it will thereafter be submitted for mediation in accordance with Section 6.9(b).

qualified and to be accepted by the parties. The mediation shall be conducted at a place and a time agreed by the parties with the mediator, or if the parties cannot agree, as designated by the mediator. The mediation shall be held within twenty
(20) days after the mediator is appointed. Each party will bear its own costs and expenses with 

  
 31 









 
respect to the mediation, including one-half of the fees and expenses of the mediator. Neither party may employ or use the mediator as a witness, consultant, expert, or counsel regarding the
dispute or any related matters. 
 6.10 Governing Law. All questions concerning the construction, validity, enforcement
and interpretation of this Agreement shall be governed by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the principles of conflicts of law thereof. Each party agrees that all Proceedings
concerning the interpretations, enforcement and defense of the transactions contemplated by this Agreement and any other Transaction Documents (whether brought against a party hereto or its respective Affiliates, employees or agents) shall be
commenced exclusively in the New York Courts. Subject to Section 6.9, each party hereto hereby irrevocably submits to the exclusive jurisdiction of the New York Courts for the adjudication of any dispute hereunder or in connection herewith or
with any transaction contemplated hereby or discussed herein (including with respect to the enforcement of any of the Transaction Documents), and hereby irrevocably waives, and agrees not to assert in any Proceeding, any claim that it is not
personally subject to the jurisdiction of any such New York Court, or that such Proceeding has been commenced in an improper or inconvenient forum. Each party hereto hereby irrevocably waives personal service of process and consents to process being
served in any such Proceeding by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Agreement and agrees that such service
shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law. EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES, TO
THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY. 

6.11 Survival. The representations and warranties contained in Sections 3.1(a) (Organization and Qualification), 3.1(b)
(Subsidiaries), 3.1(c) (Authorization; Enforcement; Validity), 3.1(e) (Filings, Consents and Approvals) and 3.1(p) (Registration Rights) shall survive for the applicable statute of limitations. All other representations and warranties contained
herein shall survive the Closing and the delivery of the Shares for a period of one (1) year from the Closing Date. The agreements and covenants contained herein shall survive for the applicable statute of limitations. 

6.12 Governing Version. This Agreement has been drafted in English, and a Russian translation has been prepared by the
Purchaser simultaneously with the execution of this Agreement and is attached hereto as Exhibit I. Such Russian version has been prepared solely for informational purposes and shall have no legal force or effect. 

6.13 Execution. This Agreement may be executed in two or more counterparts, all of which when taken together shall be considered
one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party, it being understood that both parties need not sign the same counterpart. In the event that any signature is
delivered by facsimile transmission, or by e-mail delivery of a “.pdf” format data file, such signature shall create a valid and binding obligation of the party executing (or on


  
 32 









 
whose behalf such signature is executed) with the same force and effect as if such facsimile signature page were an original thereof; provided, however, that the Purchaser must
receive from the Company originally signed copies of the Company’s signature pages to the Company Deliverables prior to the Purchaser wiring the Subscription Amount to the Company pursuant to Section 2.1(c) above. 

6.14 Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction
to be invalid, illegal, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated, and the parties hereto
shall use their good faith reasonable efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such term, provision, covenant or restriction. It is hereby stipulated and declared to
be the intention of the parties that they would have executed the remaining terms, provisions, covenants and restrictions without including any of such that may be hereafter declared invalid, illegal, void or unenforceable. 

6.15 Remedies. In the event of a breach by the Company or by a Purchaser of any of their obligations under this Agreement, the
Purchaser or the Company, as the case may be, in addition to being entitled to exercise all rights granted by law and under this Agreement, including recovery of damages, will be entitled to specific performance of its rights under this Agreement.
The Company and the Purchaser agree that monetary damages would not provide adequate compensation for any losses incurred by reason of a breach by it of any of the provisions of this Agreement and hereby further agrees that, in the event of any
action for specific performance in respect of such breach, it shall waive the defense that a remedy at law would be adequate. 

6.16 Adjustments in Share Numbers and Prices. In the event of any stock split, subdivision, dividend or distribution payable in
shares of Common Stock (or other securities or rights convertible into, or entitling the holder thereof to receive directly or indirectly shares of Common Stock), combination or other similar recapitalization or event occurring after the date
hereof, each reference in any Transaction Document to a number of shares or a price per share shall be deemed to be amended to appropriately account for such event. 
 6.17 Termination. This Agreement may be terminated and the sale and purchase of the Shares abandoned at any time prior to the Closing by either the Company or the Purchaser, upon written notice to
the other party, if the Closing has not been consummated on or prior to 5:00 p.m., California time, on the Outside Date; provided, however, that the right to terminate this Agreement under this Section 6.17 shall not be available to the
party whose failure to comply with its obligations under this Agreement has been the primary cause of the failure of the Closing to occur by such Outside Date. Nothing in this Section 6.17 shall be deemed to release any party from any liability
for any breach by such party of the terms and provisions of this Agreement or the other Transaction Documents or to impair the right of any party to compel specific performance by any other party of its obligations under this Agreement or the other
Transaction Documents.

 FORM OF COMPANY COUNSEL LEGAL OPINION 
 April 27, 2012 

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,
