 Attn: Amy H. Rice 
 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”). Oaktree will be permitted to submit the names of individuals for consideration as the Independent Designee and such individuals will be considered in good faith by 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. Promptly, and in any event

(d) Future Committees. Subject to Company’s Corporate Governance Guidelines, as they may be amended from time to time (the
“Guidelines”), the listing rules of Nasdaq and applicable law, the Board and all applicable committees of the Board will take all action necessary to ensure that each committee of the Board formed after the date of this Agreement
and during the Restricted Period includes at least one of the Oaktree Designee or the Independent Designee. The chair of any such committee will be chosen by the Board from time to time. 

8. Recusal. Oaktree understands and agrees that the Board or any of its committees, in the exercise of its fiduciary duties, may require

or enforcement of any of the obligations under this Agreement; (b) any action taken in response to actions taken or proposed by any member of the Oaktree Group with respect to Company; or (c) any proposed transaction between Company and
any member of the Oaktree Group.

any Replacement Oaktree Designee, as applicable), upon appointment to the Board, will be governed by the same laws, policies, procedures, processes, codes, rules, standards and guidelines applicable to members of the Board, including Company’s
code of conduct, insider trading policy, Regulation FD policy, related party transactions policy and the Guidelines, in each case in effect and as amended from time to time. 

10. Confidentiality. Company agrees that the Oaktree Designee may, subject to, and solely in accordance with the terms of, a customary
confidentiality agreement between Company and Oaktree, provide confidential information of Company to the members of the Oaktree Group for the purpose of assisting the Oaktree Designee in such person’s role as a director of Company


  
 -3- 













 
and related compliance matters. Such confidentiality agreement will restrict the disclosure and use by the members of the Oaktree Group and other Restricted Persons of such confidential
information. Company and Oaktree will cooperate to prepare and enter into such agreement as promptly as practicable following the execution and delivery of this Agreement. 

11. No Fiduciary Restriction. Notwithstanding anything to the contrary in this Agreement, Company and the Oaktree Group each acknowledge
that the Oaktree Designee, during the Oaktree Designee’s service as a director of Company, will not be prohibited from acting in the Oaktree Designee’s capacity as a director or from complying with the Oaktree Designee’s fiduciary
duties as a director of Company (including voting on any matter submitted for consideration by the Board, participating in deliberations or discussions of the Board, and making suggestions or raising any issues or recommendations to the Board). 

12. Director Benefits. The Oaktree Designee will be entitled to the same director benefits as other members of the Board, including
(a) reimbursement for such director’s expenses on the same basis as all other non-employee directors of Company; and (b) the same rights of indemnification and directors’ and officers’
liability insurance coverage as the other non-employee directors of Company as such rights may exist from time to time. The Independent Designee will be entitled to the same director benefits as other members

13. Assistance with Other Stockholders. From time to time during the Restricted Period, Oaktree will reasonably cooperate with Company
in conveying to, and discussing with, Company’s stockholders the support of Oaktree for the Board, including by meeting with such stockholders in consultation and coordination with Company. As reasonably requested by the Board, Oaktree will
publicly (a) disclose its support for the Board’s slate of director nominees standing for election; and (b) recommend that Company’s stockholders also support the Board’s slate of director nominees standing for election.

 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. Notwithstanding the foregoing, (A) if Institutional
Shareholder Services Inc. (“ISS”) or Glass Lewis & Co., LLC (“Glass Lewis”) recommends a vote inconsistent with the recommendation of the Board at any annual or special meeting of Company’s
stockholders during the Restricted Period with respect to (1) Company’s “say-on-pay” proposal or (2) any other proposal (other than the election
or removal of directors), then the members of the Oaktree Group will be permitted to vote in accordance with the recommendation of ISS or Glass Lewis; and (B) the members of the Oaktree Group will be permitted to vote in their sole discretion

Company or (b) is an affiliate or associate of Company and was the owner of 15 percent or more of the then-outstanding shares of voting stock of Company at any time within the three year period immediately prior to the date on which it is
sought to be determined whether such person is an interested stockholder; and the affiliates and associates of 

  
 -10- 













 
such person; provided, however, that “interested stockholder” shall not include any person whose ownership of shares in excess of the 15 percent limitation set forth
herein is the result of any action taken solely by Company; provided that such person shall be an interested stockholder if thereafter such person acquires additional shares of voting stock of Company except as a result of further corporate
action not caused, directly or indirectly, by such person. For the purpose of determining whether a person is an interested stockholder, the voting stock of Company deemed to be outstanding shall include stock deemed to be owned by the person
through application of the definition of “owner” below but shall not include any other unissued stock of Company that may be issuable pursuant to any agreement, arrangement or understanding, or upon exercise of conversion rights, warrants
or options, or otherwise.

after the passage of time) pursuant to any agreement, arrangement or understanding, or upon the exercise of conversion rights, exchange rights, warrants or options, or otherwise; provided, however, that a person shall not be deemed the
owner of stock tendered pursuant to a tender or exchange offer made by such person or any of such person’s affiliates or associates until such tendered stock is accepted for purchase or exchange; or (b) the right to vote such stock
pursuant to any agreement, arrangement or understanding; provided, however, that a person shall not be deemed the owner of any stock because of such person’s right to vote such stock if the agreement, arrangement or understanding
to vote such stock arises solely from a revocable proxy or consent given in response to a proxy or consent solicitation made to ten or more persons; or 

c) has any agreement, arrangement or understanding for the purpose of acquiring, holding, voting (except voting pursuant to a revocable proxy
or consent as described in paragraph 16(b)(ii)(6)b)(b)), or disposing of such stock with any other person that beneficially owns, or whose affiliates or associates beneficially own, directly or indirectly, such stock.

Agreement and to bind such member; (b) this Agreement has been duly authorized, executed and delivered by it and is a valid and binding obligation of such member, enforceable against it in accordance with its terms, except as enforcement
thereof may be limited by applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or similar laws generally affecting the rights of creditors and subject to general equity principles; (c) this Agreement does not and
will not violate any law, any order of any court or other agency of government, its organizational documents, or conflict with, result in a material breach of or constitute (with due notice or lapse of time or both) a default under any agreement or
other instrument to which Oaktree or such member is bound, or result in the creation or imposition of, or give rise to, any material lien, charge, restriction, claim, encumbrance or adverse penalty of any nature whatsoever; and (d) as of the
date of this Agreement, it has not, and no other member of the Oaktree Group has, directly or indirectly, compensated or entered into any agreement, arrangement or understanding to compensate any person for his or her service as a director of
Company with any cash, securities (including any rights or options convertible into or exercisable for or exchangeable into securities or any profit sharing agreement or arrangement) or other form of compensation directly or indirectly related to
Company or its securities. Oaktree represents and warrants that as of the date of this Agreement, Oaktree is the beneficial owner of an aggregate of [25,175,384] shares of Company’s common stock. 

24. Representations of Company. Company represents that this Agreement (a) has been duly authorized, executed and delivered by it
and is a valid and binding obligation of Company, enforceable against Company in accordance with its terms, except as enforcement thereof may be limited by applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or
similar laws generally affecting the rights of creditors and subject to general equity principles; (b) does not require the approval of the stockholders of Company; and (c) does not and will not violate any law, any order of any court or
other agency of government, Company’s certificate of incorporation or bylaws, each as amended from time to time, or any provision of any agreement or other instrument to which Company or any of its properties or assets is bound, or conflict
with, result in a breach of or constitute (with due notice or lapse of time or both) a default under any such agreement or other instrument, or result in the creation or imposition of, or give rise to, any material lien, charge, restriction, claim,
encumbrance or adverse penalty of any nature whatsoever. 
 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 

  
 -14- 













 
defense that there would be an adequate remedy at law; and (c) the Party against whom specific performance is sought agrees to waive any applicable right or requirement that a bond be
posted. Such remedies will not be the exclusive remedies for a breach of this Agreement, but will be in addition to all other remedies available at law or in equity. 

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.

 29. Waiver of Jury Trial. EACH OF THE PARTIES, AFTER CONSULTING OR HAVING HAD THE
OPPORTUNITY TO CONSULT WITH COUNSEL, KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVES ANY RIGHT THAT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN ANY LITIGATION BASED UPON OR ARISING OUT OF THIS AGREEMENT OR ANY COURSE OF CONDUCT, DEALING, STATEMENTS
(WHETHER ORAL OR WRITTEN), OR ACTIONS OF ANY OF THEM. 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.

 31. Notices. All notices and other communications under this Agreement must be in writing and will be deemed to have been duly
delivered and received (a) four Business Days after being sent by registered or certified mail, return receipt requested, postage prepaid; (b) one Business Day after being sent for next Business Day delivery, fees prepaid, via a reputable
nationwide overnight courier service; (c) immediately upon delivery by hand; or (d) on the date sent by email (except that notice given by email will not be effective unless either (i) a duplicate copy of such email notice is promptly
given by one of the other methods described in this paragraph 31 or (ii) the receiving Party delivers a written confirmation of receipt of such notice either by email or any other method described in this paragraph 31 (excluding

negotiations that have preceded the execution of this Agreement, and that it has executed this Agreement with the advice of such counsel. Each Party and its counsel cooperated and participated in the drafting and preparation of this Agreement, and
any and all drafts of this Agreement exchanged among the Parties will be deemed the work product of all of the Parties and may not be construed against any Party by reason of its drafting or preparation. 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.
