Ladies and Gentlemen:

This letter (this “Agreement”) constitutes the agreement between (a) Infinera Corporation (“Company”) and (b) Oaktree Optical Holdings, L.P. (“Oaktree”). Company and Oaktree are collectively referred to as the “Parties.” Oaktree and each Affiliate (as defined below) and Associate (as defined below) of Oaktree, including each of the Persons (as defined below) set forth on Exhibit A, are collectively referred to as the “Oaktree Group.”

1. Oaktree Designee. Effective as of the date of this Agreement, Company’s Board of Directors (the “Board”) will take all action necessary (including increasing the size of the Board) to appoint Amy H. Rice (the “Oaktree Designee”) as a Class I director with a term expiring at Company’s 2020 Annual Meeting of Stockholders (the “2020 Annual Meeting”). Such appointment will be effective no later than three Business Days (as defined below) following the date of this Agreement.

2. Nomination of the Oaktree Designee at the 2020 Annual Meeting. Subject to paragraph 4, Company will take all action necessary to include the Oaktree Designee on the Board’s slate of director nominees standing for election at the 2020 Annual Meeting. If the Oaktree Designee is included on the Board’s slate of director nominees at the 2020 Annual Meeting, then Company will recommend that Company’s stockholders vote, and will solicit proxies, in favor of the election of the Oaktree Designee at the 2020 Annual Meeting and otherwise support the Oaktree Designee for election in a manner no less rigorous and favorable than the manner in which Company supports its other director nominees at the 2020 Annual Meeting.

3. Replacement of the Oaktree Designee. During the Restricted Period (as defined below) but subject to paragraph 4, if the Oaktree Designee ceases to be a member of the Board for any reason, then Oaktree will have the right to identify (and the Board will take all action necessary to promptly, and in any event within five Business Days, appoint) another person (a “Replacement Oaktree Designee”) to serve as a director in place of the Oaktree Designee. Any Replacement Oaktree Designee must (a) be a principal, officer or employee of a member of the Oaktree Group; (b) be reasonably acceptable to the Board; (c) be qualified to serve as a member of the Board under all applicable corporate governance policies or guidelines of Company and the Board and applicable legal and regulatory requirements; (d) meet the independence requirements with respect to Company of the listing rules of The Nasdaq Stock Market (“Nasdaq”) (the requirements in clauses (c) and (d), the “Independence Requirements”); and

(e) have complied with Company’s procedures for new director candidates (including the full completion of a directors and officers questionnaire, undergoing a customary background check, and participating in interviews with the members of the Board’s Nominating and Governance Committee and the Board) (such procedures, the “Candidate Review Procedures”). Upon becoming a member of the Board, the Replacement Oaktree Designee will succeed to all of the rights and privileges, and will be bound by the terms and conditions, of the Oaktree Designee under this Agreement.

4. Resignation of the Oaktree Designee. Company’s obligations under paragraph 2 and paragraph 3, paragraph 5 and paragraph 6 will immediately terminate upon the earliest of: (a) the Oaktree Group no longer beneficially owning shares of Company’s common stock (which shares are determined to be Net Long Shares (as defined below)) representing in the aggregate at least five percent of Company’s then-outstanding common stock; (b) any Restricted Person (as defined below) breaching this Agreement and such breach is not cured (if capable of being cured) within 15 days after receipt by Oaktree from Company of written notice specifying the breach; or (c) the submission by any Restricted Person of any director nominations in connection with any meeting of Company’s stockholders. In addition, upon the occurrence of any event described in the previous sentence, the Oaktree Designee will, and Oaktree will take all action necessary to cause the Oaktree Designee to, concurrently resign from the Board.

5. Independent Designee. Company and Oaktree will reasonably cooperate to identify an individual (the “Independent Designee”) to serve as a Class III director with a term expiring at Company’s 2022 Annual Meeting of Stockholders. The Independent Designee must (a) not (i) be an employee, director, general partner, manager or other agent of any member of the Oaktree Group; (ii) be a limited partner, member or other investor in any member of the Oaktree Group or (iii) be party to any agreement, arrangement or understanding, written or oral, with any member of the Oaktree Group regarding such person’s service on the Board; (b) meet the Independence Requirements; (c) have complied with the Candidate Review Procedures; and (d) be unanimously recommended to the Board by the Board’s Nominating and Governance Committee (the “NGC Committee”).

Promptly, and in any event within five Business Days, after being recommended to the Board by the NGC Committee, the Board will take all action necessary (including increasing the size of the Board) to appoint the Independent Designee to the Board. Company and Oaktree intend for the Independent Designee to have been appointed to the Board no later than 120 days following the conclusion of the 2020 Annual Meeting.

6. Replacement of the Independent Designee. During the Restricted Period, if the Independent Designee ceases to be a member of the Board for any reason (other than because the Independent Designee is not nominated by the Board to stand for election at an annual meeting of stockholders of Company or is not elected by stockholders at the applicable annual meeting of stockholders), then Company and Oaktree will cooperate to identify another person (the “Replacement Independent Designee”) to serve as a director in place of the Independent Designee. The Replacement Independent Designee must (i) meet the Independence Requirements; (ii) have complied with the Candidate Review Procedures; and (iii) be unanimously recommended to the Board by the NGC Committee.

14. Voting Commitment. During the Restricted Period, at each annual or special meeting of Company’s stockholders (including any adjournments, postponements or other delays thereof) or action by written consent, Oaktree will cause all Voting Securities (as defined below) that are beneficially owned by any member of the Oaktree Group to be (a) present for quorum purposes, if applicable; and (b) voted or consented (i) in favor of the election of each person nominated by the Board for election as a director; (ii) against any proposals or resolutions to remove any member of the Board; and (iii) in accordance with the recommendation of the Board on all other proposals or business that may be the subject of stockholder action at such meeting or action by written consent.

25. Specific Performance. Each Party acknowledges and agrees that money damages would not be a sufficient remedy for any breach (or threatened breach) of this Agreement by it and that, in the event of any breach or threatened breach of this Agreement, (a) the Party seeking specific performance will be entitled to injunctive and other equitable relief, without proof of actual damages; (b) the Party against whom specific performance is sought will not plead in

26. Entire Agreement; Binding Nature; Assignment; Waiver. This Agreement constitutes the only agreement between the Parties with respect to the subject matter of this Agreement and it supersedes all prior agreements, understandings, negotiations and discussions, whether oral or written. This Agreement binds, and will inure to the benefit of, the Parties and their respective successors and permitted assigns. No Party may assign or otherwise transfer either this Agreement or any of its rights, interests, or obligations under this Agreement without the prior written approval of the other Party. Any purported transfer requiring consent without such consent is void. No amendment, modification, supplement or waiver of any provision of this Agreement will be effective unless it is in writing and signed by the affected Party, and then only in the specific instance and for the specific purpose stated in such writing. Any waiver by any Party of a breach of any provision of this Agreement will not operate as or be construed to be a waiver of any other breach of such provision or of any breach of any other provision of this Agreement. The failure of a Party to insist upon strict adherence to any term of this Agreement on one or more occasions will not be considered a waiver or deprive that Party of the right to insist upon strict adherence to that term or any other term of this Agreement in the future.

27. Severability. If any provision of this Agreement is held invalid or unenforceable by any court of competent jurisdiction, then the other provisions of this Agreement will remain in full force and effect. Any provision of this Agreement that is held invalid or unenforceable only in part or degree will remain in full force and effect to the extent not held invalid or unenforceable, and this Agreement will otherwise be construed so as to effectuate the original intention of the Parties reflected in this Agreement. The Parties further agree to replace such invalid or unenforceable provision of this Agreement with a valid and enforceable provision that will achieve, to the extent possible, the purposes of such invalid or unenforceable provision.

28. Governing Law; Forum. This Agreement is governed by and will be construed in accordance with the laws of the State of Delaware. Each of the Parties (a) irrevocably and unconditionally consents to the exclusive personal jurisdiction and venue of the Court of Chancery of the State of Delaware and any appellate court thereof (unless the federal courts have exclusive jurisdiction over the matter, in which case the United States District Court for the District of Delaware and any appellate court thereof will have exclusive personal jurisdiction); (b) agrees that it will not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any such court; (c) agrees that it will not bring any action relating to this Agreement or otherwise in any court other than the such courts; and (d) waives any claim of improper venue or any claim that those courts are an inconvenient forum. The Parties agree that mailing of process or other papers in connection with any such action or proceeding in the manner provided in paragraph 31 or in such other manner as may be permitted by applicable law, will be valid and sufficient service thereof.

No Party will seek to consolidate, by counterclaim or otherwise, any action in which a jury trial has been waived with any other action in which a jury trial cannot be or has not been waived.

30. Third Party Beneficiaries. This Agreement is solely for the benefit of the Parties and is not enforceable by any other Person.

Accordingly, any rule of law or any legal decision that would require interpretation of any ambiguities in this Agreement against any Party that drafted or prepared it is of no application and is expressly waived by each of the Parties, and any controversy over interpretations of this Agreement will be decided without regard to events of drafting or preparation.

33. Counterparts. This Agreement and any amendments to this Agreement may be executed in one or more textually-identical counterparts, all of which will be considered one and the same agreement and will become effective when one or more counterparts have been signed by each of the Parties and delivered to the other Parties, it being understood that all Parties need not sign the same counterpart. Any such counterpart, to the extent delivered by fax or .pdf, .tif, .gif, .jpg or similar attachment to electronic mail (any such delivery, an “Electronic Delivery”), will be treated in all manner and respects as an original executed counterpart and will be considered to have the same binding legal effect as if it were the original signed version thereof delivered in person. No Party may raise the use of an Electronic Delivery to deliver a signature, or the fact that any signature or agreement or instrument was transmitted or communicated through the use of an Electronic Delivery, as a defense to the formation of a contract, and each Party forever waives any such defense, except to the extent that such defense relates to lack of authenticity.

34. Headings. The headings set forth in this Agreement are for convenience of reference purposes only and will not affect or be deemed to affect in any way the meaning or interpretation of this Agreement or any term or provision of this Agreement.
