Form of Change of Control Severance Agreement for Infinera's other officers

 Exhibit 10.7 
 (VICE PRESIDENTS) 
 INFINERA CORPORATION 
 CHANGE OF CONTROL SEVERANCE AGREEMENT 
 This Change of Control Severance
Agreement (the “Agreement”) is made and entered into by and between [NAME] (“Executive”) and Infinera Corporation (the “Company”), effective as of [DATE] (the “Effective Date”). 
 RECITALS 
 1. It is expected
that the Company from time to time will consider the possibility of an acquisition by another company or other change of control. The Board of Directors of the Company (the “Board”) recognizes that such consideration can be a distraction
to Executive and can cause Executive to consider alternative employment opportunities. The Board has determined that it is in the best interests of the Company and its stockholders to assure that the Company will have the continued dedication and
objectivity of Executive, notwithstanding the possibility, threat or occurrence of a Change of Control (as defined herein) of the Company. 
 2. The Board believes that it is in the best interests of the Company and its stockholders to provide Executive with an incentive to continue his or her employment and to motivate Executive to maximize the value of the Company upon a Change
of Control for the benefit of its stockholders. 
 3. The Board believes that it is imperative to provide Executive with certain benefits
upon Executive’s termination of employment following a Change of Control. These benefits will provide Executive with enhanced financial security and incentive and encouragement to remain with the Company notwithstanding the possibility of a
Change of Control. 
 4. Certain capitalized terms used in the Agreement are defined in Section 6 below. 
 AGREEMENT 
 NOW, THEREFORE, in
consideration of the mutual covenants contained herein, the parties hereto agree as follows: 
 1. Term of Agreement. This Agreement
will terminate upon the date that all of the obligations of the parties hereto with respect to this Agreement have been satisfied. 
 2.
At-Will Employment. The Company and Executive acknowledge that Executive’s employment is and will continue to be at-will, as defined under applicable law, except as may otherwise be specifically provided under the terms of any written
formal employment agreement between the Company and Executive (an “Employment Agreement”). If Executive’s employment terminates for any reason, including (without limitation) any termination prior to a Change of Control, Executive
will not be entitled to any payments, benefits, damages, awards or compensation other than as provided by this Agreement or under his or her Employment Agreement. 

 3. Severance Benefits. 
 (a) Involuntary Termination Following a Change of Control. If (i) within twelve (12) months following a Change of
Control, (A) the Company (or any parent or subsidiary of the Company) terminates Executive’s employment without Cause, or (B) Executive resigns his or her employment as a result of a Constructive Termination, and (ii) Executive
signs and does not revoke a standard release of claims with the Company in a form acceptable to the Company, then Executive will receive the following severance from the Company: 
 (i) Severance Payment. Executive will receive severance pay (less applicable withholding taxes) for a period of six (6) months
from the date of such termination equal to the pro-rata portion of Executive’s base salary (as in effect immediately prior to (A) the Change of Control, or (B) Executive’s termination, whichever is greater). 
 (ii) Equity Awards. 
 (1) Initial Equity Awards. Fifty percent (50%) of the original total of each equity award granted to Executive in connection with Executive’s initial employment with the Company (the “Initial
Awards”) will immediately vest and, if applicable, become exercisable (that is, in addition to the portion of any such Initial Awards that had vested as of such termination, but in no event more than the original amount of such Initial Awards),
but only if Executive was initially employed with the Company as a Vice President or other executive officer. The Initial Awards will, to the extent applicable, remain exercisable following Executive’s termination for the period prescribed in
the related award agreement. 
 (2) Subsequent Equity Awards. Fifty percent (50%) of the then unvested portion of
any equity awards granted to Executive following the Initial Awards and while Executive was serving as a Vice President or other executive officer of the Company (the “Subsequent Awards”) will immediately vest and, if applicable, become
exercisable. The Subsequent Awards will, to the extent applicable, remain exercisable following Executive’s termination for the period prescribed in the related award agreements. 
 (iii) Continued Employee Benefits. Executive will receive Company-paid coverage for a period of six (6) months for Executive
and Executive’s eligible dependents under the Company’s Benefit Plans. 
 (b) Timing of Severance Payments.
Subject to Section 3(f), the Company will pay the severance payments to which Executive is entitled as salary continuation on the same basis and timing as in effect immediately prior to the Change of Control. If Executive should die before all
amounts have been paid, such unpaid amounts will be paid in a lump-sum payment (less any withholding taxes) to Executive’s designated beneficiary, if living, or otherwise to the personal representative of Executive’s estate. 
 (c) Voluntary Resignation; Termination For Cause. If Executive’s employment with the Company terminates (i) voluntarily
by Executive (other than as a result of a Constructive Termination) or (ii) for Cause by the Company (or any parent or subsidiary of the Company), then 

  

 -2- 

 
Executive will not be entitled to receive severance or other benefits except for those (if any) as may then be established under the Company’s then
existing severance and benefits plans and practices or pursuant to other written agreements with the Company, including, without limitation, any Employment Agreement. 
 (d) Disability; Death. If the Company terminates Executive’s employment as a result of Executive’s Disability, or
Executive’s employment terminates due to his or her death, then Executive will not be entitled to receive severance or other benefits except for those (if any) as may then be established under the Company’s then existing written severance
and benefits plans and practices or pursuant to other written agreements with the Company, including, without limitation, any Employment Agreement. 
 (e) Exclusive Remedy. In the event of a termination of Executive’s employment with the Company (or any parent or subsidiary of the Company), the provisions of this Section 3 are intended to be and are
exclusive and in lieu of any other rights or remedies to which Executive or the Company may otherwise be entitled, whether at law, tort or contract, in equity, or under this Agreement. Executive will be entitled to no benefits, compensation or other
payments or rights upon termination of employment other than those benefits expressly set forth in this Section 3. 
 (f)
Section 409A. Notwithstanding anything to the contrary in this Agreement, any cash severance payments otherwise due to Executive pursuant to Section 3 or otherwise on or within the six (6)-month period following Executive’s
termination will accrue during such six (6)-month period and will become payable in a lump sum payment on the date six (6) months and one (1) day following the date of Executive’s termination, provided, that such cash severance
payments will be paid earlier, at the times and on the terms set forth in the applicable provisions of Section 3, if the Company reasonably determines that the imposition of additional tax under Section 409A of the Internal Revenue Code of
1986, as amended (the “Code”), will not apply to an earlier payment of such cash severance payments. In addition, this Agreement will be deemed amended to the extent necessary to avoid imposition of any additional tax or income recognition
prior to actual payment to Executive under Code Section 409A and any temporary, proposed or final Treasury Regulations and guidance promulgated thereunder and the parties agree to cooperate with each other and to take reasonably necessary steps
in this regard. 
 4. Limitation on Payments. In the event that the severance and other benefits provided for in this Agreement or
otherwise payable to Executive (i) constitute “parachute payments” within the meaning of Section 280G of the Code and (ii) but for this Section 4, would be subject to the excise tax imposed by Section 4999 of the
Code, then Executive’s severance benefits under Section 4(a)(i) will be either: 
  

	 	(a)	delivered in full, or 

  

	 	(b)	delivered as to such lesser extent which would result in no portion of such severance benefits being subject to excise tax under Section 4999 of the Code,

  

 -3- 

 whichever of the foregoing amounts, taking into account the applicable federal, state and local income taxes and the
excise tax imposed by Section 4999, results in the receipt by Executive on an after-tax basis, of the greatest amount of severance benefits, notwithstanding that all or some portion of such severance benefits may be taxable under
Section 4999 of the Code. Unless the Company and Executive otherwise agree in writing, any determination required under this Section 4 will be made in writing by the Company’s independent public accountants immediately prior to Change
of Control (the “Accountants”), whose determination will be conclusive and binding upon Executive and the Company for all purposes. For purposes of making the calculations required by this Section 4, the Accountants may make
reasonable assumptions and approximations concerning applicable taxes and may rely on reasonable, good faith interpretations concerning the application of Sections 280G and 4999 of the Code. The Company and Executive will furnish to the Accountants
such information and documents as the Accountants may reasonably request in order to make a determination under this Section 4. The Company will bear all costs the Accountants may reasonably incur in connection with any calculations
contemplated by this Section 4. 
 5. Definition of Terms. The following terms referred to in this Agreement will have the
following meanings: 
 (a) Benefit Plans. For purposes of this Agreement, “Benefit Plans” means plans,
policies or arrangements that the Company sponsors (or participates in) and that immediately prior to Executive’s termination of employment provide Executive and/or Executive’s eligible dependents with medical, dental, and/or vision
benefits. Benefit Plans do not include any other type of benefit (including, but not by way of limitation, disability, life insurance or retirement benefits). A requirement that the Company provide Executive and Executive’s eligible dependents
with coverage under the Benefit Plans will not be satisfied unless the coverage is no less favorable than that provided to senior executives of the Company at any applicable time during the period Executive is entitled to receive severance pursuant
to Section 3. The Company may, at its option, satisfy any requirement that the Company provide coverage under any Benefit Plan by (i) reimbursing Executive’s premiums under Title X of the Consolidated Budget Reconciliation Act of
1985, as amended (“COBRA”) after Executive has properly elected continuation coverage under COBRA (in which case Executive will be solely responsible for electing such coverage for his eligible dependents), or (ii) providing coverage
under a separate plan or plans providing coverage that is no less favorable or by paying Executive a lump-sum payment which is, on an after-tax basis, sufficient to provide Executive and Executive’s eligible dependents with equivalent coverage
under a third party plan that is reasonably available to Executive and Executive’s eligible dependents. 
 (b)
Cause. “Cause” is defined as: (i) Executive’s willful failure to substantially to perform his or her duties and responsibilities to the Company or deliberate violation of a Company policy; (ii) Executive’s
commission of any act of fraud, embezzlement, dishonesty or any other willful misconduct that has caused or is reasonably expected to result in material injury to the Company; (iii) unauthorized use or disclosure by Executive of any proprietary
information or trade secrets of the Company or any other party to whom Executive owes an obligation of nondisclosure as a result of his or her relationship with the Company; or (iv) Executive’s willful breach of any of his or her
obligations under any written agreement or covenant with the Company. The determination as to whether Executive is being terminated for Cause will be made in good faith by the Company and will be final and binding on Executive. 
  

 -4- 

 (c) Change of Control. “Change of Control” of the Company is defined as:

 (i) any “person” (as such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as
amended) becomes the “beneficial owner” (as defined in Rule 13d-3 under said Act), directly or indirectly, of securities of the Company representing fifty percent (50%) or more of the total voting power represented by the
Company’s then outstanding voting securities; 
 (ii) the consummation of the sale or disposition by the Company of all
or substantially all of the Company’s assets; 
 (iii) the consummation of a merger or consolidation of the Company with
any other corporation, other than a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting
securities of the surviving entity or its parent) at least fifty percent (50%) of the total voting power represented by the voting securities of the Company or such surviving entity or its parent outstanding immediately after such merger or
consolidation; or 
 (iv) a change in the composition of the Board occurring within a two (2) year period, as a result of
which less than a majority of the directors are Incumbent Directors. “Incumbent Directors” means directors who either (A) are directors of the Company as of the date hereof, or (B) are elected, or nominated for election, to the
Board with the affirmative votes of at least a majority of the directors of the Company at the time of such election or nomination (but will not include an individual whose election or nomination is in connection with an actual or threatened proxy
contest relating to the election of directors to the Company). 
 (d) Constructive Termination. “Constructive
Termination” will mean Executive’s resignation as a result of, and within thirty (30) days following: (i) a reduction in Executive’s job, duties or responsibilities in a manner that is substantially inconsistent with the
position, duties or responsibilities held by Executive immediately before such reduction, or (ii) a reduction in Executive’s base salary other than in connection with and consistent with a general reduction of all employee base salaries.

 (e) Disability. “Disability” will mean that Executive has been unable to perform his Company duties as the
result of his incapacity due to physical or mental illness, and such inability, at least twenty-six (26) weeks after its commencement, is determined to be total and permanent by a physician selected by the Company or its insurers and acceptable
to Executive or Executive’s legal representative (such Agreement as to acceptability not to be unreasonably withheld). Termination resulting from Disability may only be effected after at least thirty (30) days’ written notice by the
Company of its intention to terminate Executive’s employment. In the event that Executive resumes the performance of substantially all of his duties hereunder before the termination of his employment becomes effective, the notice of intent to
terminate will automatically be deemed to have been revoked. 
  

 -5- 

 6. Successors. 
 (a) The Company’s Successors. Any successor to the Company (whether direct or indirect and whether by purchase, merger,
consolidation, liquidation or otherwise) to all or substantially all of the Company’s business and/or assets will assume the obligations under this Agreement and will agree expressly to perform the obligations under this Agreement in the same
manner and to the same extent as the Company would be required to perform such obligations in the absence of a succession. For all purposes under this Agreement, the term “Company” will include any successor to the Company’s business
and/or assets which executes and delivers the assumption agreement described in this Section 6(a) or which becomes bound by the terms of this Agreement by operation of law. 
 (b) Executive’s Successors. The terms of this Agreement and all rights of Executive hereunder will inure to the benefit of,

this Agreement will be in writing and will be deemed to have been duly given when personally delivered or when mailed by U.S. registered or certified mail, return receipt requested and postage prepaid. In the case of Executive, mailed notices will

attention of its President. 
 (b) Notice of Termination. Any termination by the Company for Cause or as a result of a
voluntary resignation will be communicated by a notice of termination to the other party hereto given in accordance with Section 7(a) of this Agreement. Such notice will indicate the specific termination provision in this Agreement relied upon,
will set forth in reasonable detail the facts and circumstances claimed to provide a basis for termination under the provision so indicated, and will specify the termination date (which will be not more than thirty (30) days after the giving of
such notice). 
 8. Arbitration. 
 (a) Any dispute or controversy arising out of, relating to, or in connection with this Agreement, or the interpretation, validity, construction, performance, breach, or termination thereof, will be settled by binding

 (b) The arbitrator(s) will apply California law to the merits of any dispute or claim, without reference to
conflicts of law rules. The arbitration proceedings will be governed by federal arbitration law and by the Rules, without reference to state arbitration law. Executive hereby

ARISING OUT OF, RELATING TO, OR IN CONNECTION WITH THIS AGREEMENT, OR THE INTERPRETATION, VALIDITY, CONSTRUCTION, PERFORMANCE, BREACH OR TERMINATION THEREOF TO BINDING ARBITRATION, CONSTITUTES A WAIVER OF EXECUTIVE’S RIGHT TO A JURY TRIAL AND

the time frames specified in the escrow agreement and such failure is not cured within [**], Vendor’s failure shall be a Default under Section 9.1 of this Agreement. 
 3.3 Escrow Agreement. Vendor agrees that the Deposits shall be governed by the terms of an escrow agreement mutually acceptable to and executed by BTE, Vendor and Escrow Agent (“Escrow Agreement”),
which shall contain terms for the release of the Deposits upon one of the following events (“Release Events”): (a) Vendor’s discontinuation of Maintenance and Support Services for the Licensed Software; (b) the institution
of bankruptcy, receivership, insolvency, reorganization or other similar proceedings by or against Vendor under the Federal Bankruptcy Code, if such proceedings have not been dismissed or discharged within thirty (30) calendar days after they

	 	(a)	Acceptance by BTE of the First Order Products comprising the field trial Products pursuant to the requirements of Article 6 and the agreed to Acceptance Test Plan; and

  

	 	(b)	Timely delivery and Acceptance of any Feature Enhancements; and 

  

	 	(c)	Vendor’s compliance with the material terms and conditions of this Agreement. 

 Within thirty days following March 31, 2007, the parties shall determine whether BTE has met the Commitment. In the event that BTE does not purchase
an amount of Products and Services from Vendor equal to the Commitment, Vendor’s sole and exclusive remedy shall be to invoice BTE for the portion of the Spares, Software and Services that were provided by Vendor to BTE at no cost for
Procurement Documents submitted on or prior to March 10, 2006 (the “Overbuild Incentives”) equal to the proportionate percentage shortfall in the Commitment in accordance with the applicable Prices set forth in this Agreement. For
example, if the Commitment is [**] and BTE purchased [**] from Vendor on or prior to March 31, 2007, then Vendor would be entitled to invoice BTE for twenty five percent (25%) (e.g. [**] Commitment) of the Overbuild Incentives. 

ARTICLE 8 – PROCUREMENT 
 8.1 Procurement
Documents. Each Procurement Document shall include the following terms, as applicable, for the Product(s) or Services ordered thereunder: (a) quantity; (b) complete pricing; (c) model number; (d) configuration;
(e) delivery destination; (f) delivery date (herein called “Delivery Date”); (g) installation date (herein called “Installation Date”); and (h) Service date. Subject to the terms of this Agreement, during the
Term of this Agreement, Vendor agrees to accept all Procurement Documents for Products and Services as submitted by BTE in compliance with the terms of this Agreement; provided, however, that Vendor shall have the right to conduct a credit
verification with respect to all BTE Affiliates prior to acceptance of a Procurement Document from such BTE Affiliate and seek appropriate funding confirmation prior to acceptance. Vendor shall acknowledge its written acceptance of a Procurement
Document within seven (7) business days of submission by BTE or provide BTE with written rejection of such Procurement Document specifying the reason for non- 

  

 13 
 [**] – Confidential treatment has been requested for the bracketed portions. The confidential redacted portion has been omitted and filed separately with the Securities and Exchange Commission. 

 
compliance of the Procurement Document with the terms of this Agreement. Any proposed modification by Vendor of the terms set forth in a Procurement Document
shall be deemed a rejection of the Procurement Document by Vendor unless BTE notifies Vendor of BTE’s acceptance of such modifications. In the event Vendor fails to timely deliver a notice of either acceptance or rejection of the Procurement
Document, Vendor shall be deemed to have accepted the Procurement Document without modification and to have agreed to sell and deliver to BTE the Products or Services as delineated therein in accordance with the Procurement Document. 
 8.2 Cancellation of Procurement Document. Except as otherwise mutually agreed to and specified in a Procurement Document, BTE may cancel a Procurement Document
for Product(s), or any part thereof, without penalty provided that BTE provides Vendor with written notice of such cancellation, and such written notice is received by Vendor prior to either (i) the Delivery Date for Products set forth in
Section 8.5.1, or (ii) the lead times for Products set forth in Sections 8.5.2 and 8.5.3. BTE may, upon written notice to Vendor, which notice is received by Vendor at least two (2) weeks prior to the Delivery Date or actual shipment
date, whichever is earlier, postpone the Delivery Date of some or all of the Product(s) for up to eight (8) weeks, without penalty. BTE may, upon written notice to Vendor, which notice is received by Vendor prior to the Delivery Date or actual
shipment date, whichever is earlier, change the destination to which some or all of the Products are to be delivered without penalty. BTE shall specify the revised Delivery Date, and as applicable, Installation Date, in the written notice to Vendor.

 8.3 Delivery Terms. Vendor shall cause the Products to be shipped and delivered to the destination, cleared for import in international locations,
as set forth in each Procurement Document on or before the Delivery Date. All Products shall be delivered DDP (Incoterms 2000) named place of destination provided, however, that BTE agrees to reimburse Vendor for applicable costs of shipping and
insurance, together with all applicable government fees related to customs, duties, taxes and other such charges, including any applicable VAT charges. All taxes collected from BTE hereunder shall be invoiced to BTE in a manner complying with the
laws of the jurisdiction whose tax is being collected, and in the case of non-United States taxes, Vendor agrees that BTE may reserve the right to designate one of its Affiliates as the addressee of such invoice, so long as Vendor and BTE, or
applicable Affiliate(s) of each party, establish a legal relationship for the purpose of such invoicing. BTE may require Vendor to utilize its named shipper from time to time. The delivery destinations set forth in the Procurement Document may be
BTE’s premise or any other location which BTE may direct. 
 8.4 Forecasts. In order to enable Vendor to schedule production and shipment for
Overbuild Products (as defined in Section 8.5.3 below), BTE agrees to provide Vendor, beginning upon the Effective Date and continuing thereafter during the Term, by the first day of each calendar month, a non-binding, good faith rolling
forecast of its anticipated requirements for Overbuild Products, by month, in each of the following three (3) months. BTE may aggregate in its forecast the anticipated requirements for Overbuild Products from BTE and its Affiliates, or each BTE
Affiliate may submit a separate forecast. [**]. 
 8.5 Order Lead Times. Vendor agrees that the Delivery Date for all Products purchased by BTE
pursuant to a Procurement Document received by Vendor on or after July 15, 2005, via standard shipment (non-expedited) terms, will be as follows: 
 8.5.1 Rapid Deployment Program. Vendor agrees that it will establish an inventory of the following Products for purposes of a rapid deployment program (“Rapid Deployment Program”): Tributary Adaptor
Modules (“TAMs”), Tributary Optical Modules, Digital Transport Chassis, Management Control Modules (“MCMs”), and Y-cables (if purchased by BTE) (collectively, the “Rapid Deployment Products”). Subject to the inventory
limitations set forth herein, Vendor agrees that it will deliver to BTE all Rapid Deployment Products within [**] of the date of Vendor’s receipt of a Procurement Document for such Rapid Deployment Products. The number of TAMs to be included in
the Rapid Deployment Program shall be the lower of [**] of available TAM slots for Equipment deployed in BTE’s network or (b) [**] TAMs (BTE to determine mix of TAMs). Vendor agrees to restock each Rapid Deployment 

  

 14 
 [**] – Confidential treatment has been requested for the bracketed portions. The confidential redacted portion has been omitted and filed separately with the Securities and Exchange Commission. 

 
Product within thirty days of the shipment of such Rapid Deployment Product. If Vendor fails to maintain an average delivery time of [**] days or less for
two consecutive months, or BTE orders [**] or more of the available TAMs in the Rapid Deployment Program for [**] consecutive months, then the parties agree to meet to determine an appropriate increase in the available pool of TAMS in the Rapid
Deployment Program. Vendor agrees that it shall keep the Rapid Deployment Products for the sole benefit of BTE and Vendor shall not pull from the inventory of Rapid Deployment Products to satisfy Procurement Documents submitted by BTE for the
delivery of Channel Products (as defined in Section 8.5.2). 
 8.5.2 Channel Products. Contingent upon BTE’s Capacity
Notification (as defined herein), Vendor agrees to deliver to BTE all Products other than the Overbuild Products (as set forth in Section 8.5.3) within [**] weeks of the date of Vendor’s receipt of a Procurement Document for such Products
(collectively the “Channel Products”). BTE agrees that it shall promptly notify Vendor when [**] of the deployed Product capacity on any particular route overbuild is utilized or, as applicable, will be utilized based upon pending customer
orders (the “Capacity Notification”). BTE shall, as part of the Capacity Notification, specify the applicable type or configuration for the Channel Products expected to be ordered by BTE in future Procurement Documents for the routes which
are the subject of the Capacity Notification. 
 8.5.3 Overbuild Products. Vendor agrees to deliver the following volumes of Digital
Transport Chassis ANSI packages (“DTCs”), redundant Management Control Modules (“MCMs”), Band Multiplexing Modules (“BMMs”) (DTCs, MCMs and BMMs each referred to as “DTNs”); Optical Transport Chassis ANSI
packages, (“OTCs”), redundant Optical Management Modules (“OMMs”), Optical Amplification Modules (“OAMs”) (OTCs, OMMs and OAMs each referred to as “OTNs”); and Dispersion Compensation Modules
(“DCMs”) and Dispersion Compensation Module Chassis (“DMCs”), which may be considered DTNs or OTNs, depending on the application, within the specified time period from Vendor’s receipt of a Procurement Document for the
Overbuild Products: 
  

			
	Overbuild Products	  	Delivery Interval:
	Up to [**] DTNs and/or [**] OTNs	  	[**] weeks (whether or not forecasted)
	[**] DTNs and/or [**] OTNs	  	[**] weeks (whether or not forecasted)
	Greater quantity	  	[**] weeks (whether or not forecasted)

 8.5.4 Remedy. On a monthly basis, BTE shall determine if Vendor has been late in delivering
Product to BTE in accordance with the delivery intervals set forth in this Section 8.5. If Vendor has been late in delivering Product under any Procurement Document(s), BTE may require Vendor to increase the inventory of Product in the Rapid
Deployment Program by up to [**] of the total value of the applicable Procurement Document(s) for that month (the “Additional Product”). BTE shall determine the mix of the Additional Product to be stocked in the Rapid Deployment Program.
The parties further agree that such Additional Product shall be maintained by Vendor as part of the Rapid Deployment Program until Vendor has met all of the delivery intervals for all Procurement Documents for a period of [**] consecutive days.
After such [**] period, Vendor shall have the option of removing the Additional Product from the Rapid Deployment Program. The Parties acknowledge and agree to add [**] days to the lead times for delivery dates for all orders with a destination
other than the United States or Canada. As additional Territories are added, the parties shall mutually agree on any required modification to the delivery lead times for such new Territory. 
 8.6 TOM Certification. Vendor agrees to certify up to a total of four (4) TOM modules within any one year period at BTE’s request. In order to get a TOM
certified, BTE will be required to make a request in writing that includes at a minimum [**]. In addition to providing the Certification Specification, BTE shall provide to Vendor [**] (collectively, the “Certification Materials”). For
example, for [**]. 
  

 15 
 [**] – Confidential treatment has been requested for the bracketed portions. The confidential redacted portion has been omitted and filed separately with the Securities and Exchange Commission. 

 Vendor agrees to use all reasonable commercial efforts to complete
the TOM certification process and return to BTE the TOM samples provided within [**] days of receipt of the Certification Materials. The following circumstances may prevent Vendor from completing the certification within such [**] day period:
(i) incompatibility of the requested TOM module with the Vendor system specifications, (ii) inability to obtain adequate quantities of the requested TOM module for certification or (iii) lack of cooperation from the 3rd party vendor. Upon completion of the certification, BTE shall be able to use the certified TOM software feature as part of the
then current software release. 
 The parties acknowledge and agree that any 3rd party TOM shall not be covered under any Vendor warranty or return program. 
 8.7 Title Transfer. Title to and risk of loss respecting Equipment shall pass to BTE after possession transfers to BTE at the delivery destination. Vendor agrees
that it shall convey title to the Equipment, and a license to the Licensed Software, to BTE free and clear of all liens, encumbrances and claims of any nature. 
 ARTICLE 9— DEFAULT AND REMEDIES 
 9.1 Default Events. Each of the following events shall constitute a
default (“Default”) under this Agreement and shall be considered a material breach of this Agreement, and shall allow a party, as applicable, to seek the remedies under this Agreement: 
 (a) Vendor’s failure to maintain insurance coverage required by Section 12.2; 
 (b) Failure of a party to timely observe or perform any material covenant, agreement, obligation, term or condition required to be observed or performed
under this Agreement or an applicable Statement of Work which is not cured within the time frames, if any, set forth in this Agreement or within thirty (30) days of notice of said breach if no specific time to cure is specified; provided,
however, that neither party shall be determined to be in breach for any failure that results from delays caused by the other party or its agents. 
 (c) The
institution of bankruptcy, receivership, insolvency, reorganization or other similar proceedings by or against a party under any section or chapter of the United States Bankruptcy Code, as amended, or under any similar laws or statutes of the United
Status or any state thereof, if such proceedings have not been dismissed or discharged within 30 days after they are instituted; the insolvency or making of any assignment for the benefit of creditors or the admittance by a party of any involuntary
debts as they mature; the institution of any reorganization arrangement or other readjustment of debt plan of a party not involving the United States Bankruptcy Code. 
 9.2 Remedies Upon Default of BTE. Vendor agrees that Vendor’s rights upon the Default of BTE are limited exclusively to those set forth in this Section 9.2. Vendor may, at its option, elect any one or
more of the following: 
 9.2.1 Actual Damages. Vendor shall be entitled to recover actual amounts owed by BTE to Vendor accruing on or
before the date of termination including reasonable expenses, attorney’s fees and litigation costs; 
 9.2.2 Termination. Vendor
shall be entitled to terminate this Agreement except for: (a) any full paid licenses for Software which BTE shall have a continued right to use; and (b) Maintenance and Support Services related to such licenses, unless the Default is based
on the failure of BTE to pay for such services. Notwithstanding the foregoing, Vendor may terminate a

 [**] – Confidential treatment has been requested for the bracketed portions. The confidential redacted portion has been omitted and filed separately with the Securities and Exchange Commission. 

 fully-paid license for Licensed Software and any related Maintenance and Support Services in the event
BTE breaches any provision of Section 12.7, Confidential Information, or Section 3.1, Software License. 
 9.3 Remedies Upon Default of Vendor.
BTE agrees that upon the occurrence of a Default of Vendor, BTE’s rights are limited exclusively to those set forth in this Section 9.3. BTE may, at its option, elect one or more of the following remedies (a) recover actual
damages caused by the Default of Vendor including reasonable expenses, attorney’s fees and litigation costs; (b) terminate this Agreement and all then-outstanding Procurement Documents; (c) if the Default relates to a Statement of
Work, terminate such Statement of Work, return any Materials or Products related thereto to Vendor and receive a refund of the amount paid under the Statement of Work; and (d) reject any Products that have not been Accepted by BTE and that
relate to such Default and receive a full refund of fees paid for such Products and all expenses associated with such rejection; provided, however, that if BTE elects to reject such non-Accepted Product it must return such non-Accepted Product to
Vendor. 
 ARTICLE 10 — INDEMNITY AND LIABILITY 
 10.1 Infringement Claims. Vendor shall defend, indemnify and hold harmless BTE from and against any and all claims, suits, liabilities, expenses, attorney’s fees or damages (collectively
“Claims”) for any alleged or actual infringement or violation of any third party’s copyright, patent, trade secret, trademark or other intellectual property right arising in connection with this Agreement and any act or omission
hereunder. Vendor’s obligations hereunder are conditioned upon: (i) BTE giving Vendor prompt written notice of all Claims; (ii) Vendor being given full authority to assume the sole defense thereof through its own counsel and to
compromise or settle any suits so far as this may be done without prejudice to the right of BTE to continue the use of the alleged infringing system, method, apparatus, proprietary information, work or mark; and (iii) BTE cooperating fully with
Vendor to facilitate defense or settlement of such Claim. In any such suit, if the use of the alleged infringing intellectual property is held to constitute an infringement and is enjoined, or if in light of any Claim Vendor deems it advisable to do
so and can do so without, in BTE’s reasonable opinion, impairing or adversely affecting the Equipment or BTE’s use thereof, Vendor may at Vendor’s sole option and expense: (i) procure the right to continue the use of the same for
BTE; or (ii) replace or modify the same to be free of the infringement claim. Any settlement of any such Claim that imposes any liability or limitation on BTE shall not be entered into without the prior written consent of BTE. Should BTE enter
into settlement of any such Claim without Vendor as a signatory to the settlement and Vendor is not in breach of its obligations, BTE waives any claims that it may have to Vendor for contribution to the settlement and/or defense costs. 

Notwithstanding the foregoing, Vendor shall have no obligation to defend or settle any Claim for any infringement or other violation of any intellectual property
right: (i) arising solely from compliance with BTE’s custom specifications or designs, (ii) relating solely to use of any Equipment furnished hereunder in combination with another product not furnished by Vendor, unless such
combination is the Equipment’s necessary or inherent use or a specific use for which the Equipment is sold by Vendor to BTE, or (iii) relating solely to a Claim based on intellectual property rights owned by BTE or any of its affiliates.
This Section 10.1 states Buyer’s sole and exclusive remedy in the event that Equipment infringes on the intellectual property right of any third party. 
 In the event the award or settlement of a Claim is based partially on an indemnified Claim described above and partially on a non-indemnified Claim, any payments and reasonable attorney fees incurred in connection with such Claims are to be
apportioned between the Parties in accordance with the degree of cause attributable to each Party; however, nothing in the foregoing shall reduce or limit Vendor’s duty to defend BTE against alleged infringement Claims. 
 10.2 Property and Bodily Injury. Each party shall defend, indemnify and hold harmless the other party from and against any and all Claims respecting property,
including loss of use thereof, injuries to persons, including death, and from any other Claims on account of acts or omissions of such party, or any of its subcontractors, 
  

 17 

 suppliers, officers, agents, employees or servants, provided, however, a party’s duty hereunder shall not arise to
the extent such Claims are caused by the negligence of the other party. 
 10.3 Other Agreements. Each Party shall defend, indemnify and hold harmless
the other party from and against any and all reasonable losses, damages, costs, expenses and reasonable attorney’s fees suffered or incurred on account of any breach of any other covenant or agreement set forth in this Agreement not otherwise
set forth in this Article 10. 
  

	10.4	Limitation of Liability. 

 10.4.1 LIMITATION UPON
TYPES OF RECOVERABLE DAMAGES. EXCEPT AS OTHERWISE PROVIDED IN SECTION 10.4.2, NEITHER PARTY SHALL BE LIABLE FOR ANY LOST PROFITS, CONSEQUENTIAL, INCIDENTAL, INDIRECT, EXEMPLARY, SPECIAL OR PUNITIVE DAMAGES, REGARDLESS OF
WHETHER THE CLAIM GIVING RISE TO SUCH DAMAGES IS BASED UPON BREACH OF WARRANTY, BREACH OF CONTRACT OR TORT, EVEN IF A PARTY HAS BEEN ADVISED OF THE POSSIBILITY THEREOF. EXCEPT AS OTHERWISE PROVIDED IN SECTION 10.4.2, THE AGGREGATE LIABILITY
OF A PARTY UNDER THIS AGREEMENT WHETHER ARISING OUT OF BREACH OF CONTRACT (INCLUDING BUT NOT LIMITED TO BREACH OF WARRANTY) OR TORT (INCLUDING BUT NOT LIMITED TO NEGLIGENCE AND STRICT LIABILITY), SHALL IN NO EVENT EXCEED [**]. THE PROVISIONS
OF THIS SECTION SHALL SURVIVE THE EXPIRATION OR TERMINATION OF THIS AGREEMENT 
 10.4.2 EXCLUSIONS FROM LIMITATIONS OF LIABILITY.
NOTWITHSTANDING ANYTHING CONTAINED HEREIN TO THE CONTRARY, THE LIMITATIONS OF LIABILITY CONTAINED IN THIS SECTION 10.4, LIMITATION OF LIABILITY, SHALL NOT APPLY TO: [**]. 
 ARTICLE 11 — REPRESENTATIONS AND WARRANTIES 
 11.1 Performance Warranty. Vendor
represents and warrants to BTE that the Products shall perform on the System in accordance with the Documentation (“Product Performance Warranty”) for [**] (“Product Performance Warranty Term”) from the date of Acceptance by BTE
of such Products. Any defective Products failing to conform to the Product Warranty which is discovered by BTE within the Product Performance Warranty Term (whether such defects are observed before or after Acceptance of the Product) shall be
promptly corrected or replaced by Vendor, in no event later than [**] from the date of return of the Product to Vendor by BTE (or such other time period as mutually agreed upon by the parties). BTE agrees to notify Vendor and, if applicable and as
requested by Vendor, return such Product to Vendor promptly after any such defects are observed. The parties acknowledge and agree that Vendor shall not be liable pursuant to this Section 11.1 for defects to a Product that are caused by abuse
or improper use, improper maintenance repair other than as performed by Vendor or its authorized service agents, improper storage or by acts of nature or negligent handling. In the event Vendor fails to so repair or replace within the specified time
period, BTE may return the Product to Vendor for a full refund of the amount paid by BTE for the Product. Each party shall be responsible for its respective shipping and insurance costs associated with the shipment of Product to the other party for
purposes of this warranty. 
 11.2 Media Warranty. Vendor warrants for a period of [**] from the date of Acceptance of the Software that the tapes,
diskettes, and other media containing the Software shall be free from defects in materials and workmanship. Vendor shall repair or replace nonconforming tapes, diskettes or other media containing the Software promptly, but in no event more than five
(5) business days following notice from BTE. 
  

 18 
 [**] – Confidential treatment has been requested for the bracketed portions. The confidential redacted portion has been omitted and filed separately with the Securities and Exchange Commission. 

 11.3 Disabling Code/Virus Warranty. Vendor represents and warrants to BTE that the Software does not and will not
contain any virus, worm, trap door, counter, clock, timer, operational limiting routine or copy protection devices (collectively “Disabling Codes”) that would erase data or otherwise cause the System to become inoperable or incapable of
being used in the manner in which it was designed or intended. In the event BTE or Vendor discover any Disabling Codes in the Software, Vendor shall promptly, but in no more than five (5) business days following such discovery, repair, replace
or otherwise correct the System, the Software or any part thereof, affected by the Disabling Codes and shall take all necessary steps to restore any and all data or Source Code lost, destroyed or otherwise affected by the Disabling Code, all at no
additional cost to BTE. This warranty shall remain in full force and effect until BTE discontinues use of the Software. 
 11.4 Processing Warranty.
Vendor represents and warrants that the Software provided under this Agreement shall accurately recognize and process date and time data (including, but not limited to, calculating, comparing, and sequencing) for all leap year calculations. In the
event of a breach of this warranty, Vendor shall promptly, but in no more than five (5) business days following notification of the breach, repair, replace or otherwise correct the System, the Software or any parts thereof, affected by the
breach and shall take all necessary steps to restore any and all data or source code lost, destroyed or otherwise affected by the breach, all at no additional cost to BTE. This warranty is perpetual and shall survive the expiration of any other
warranty period or the termination of this Agreement. 
 11.5 Pending Claims Warranty. As of the date of this Agreement, there are no actions, suits
or proceedings pending and served against Vendor before any court or administrative agency that would materially impair Vendor’s performance of its obligations under this Agreement and Vendor has disclosed to BTE any overtly threatened action,
suit or proceeding with respect to such matter of which Vendor is actually aware. 
 11.6 Warranty of Authority. Each Party is duly qualified to do
business and is in good standing in the localities in which it is required to do so. Each Party has full power and authority to execute, deliver and perform its obligations under this Agreement. The execution, delivery and performance of this
Agreement by a Party have been duly and validly authorized by all necessary action on the part of such Party. The execution and delivery of this Agreement by a Party and the performance of the terms, covenants and conditions contained herein will
not violate the articles of incorporation or by-laws of such Party, or any order of a court or arbitrator, and will not conflict with and will not constitute a material breach of, or default under, the provisions of any material contract by which
such Party is bound. This warranty shall survive the expiration or termination of this Agreement. 
 11.7 Warranty of Title. Vendor represents that it
has the full, perpetual authority to license or sublicense all Software provided to BTE under this Agreement, and has good and marketable title to all Products and Materials (except third party Software) provided to BTE under this Agreement. This
warranty shall survive the expiration or termination of this Agreement. 
 11.8 Services Warranty. The Services will be performed: (a) in a
diligent, professional and workmanlike manner in accordance with the highest applicable industry standards; (b) in accordance with this Agreement and the applicable Statement of Work; and (c) by experienced and qualified personnel.

 11.9 Pass-Through Warranties. Vendor shall secure from the applicable Equipment or third party Software manufacturers, and assign and pass through
to BTE, at no additional cost to BTE, such warranties as may be available with respect to such Equipment and Software. Such assignment shall not, however, relieve Vendor of any of the warranty obligations contained herein. In the event such
warranties are not assignable to BTE, Vendor shall enforce, as necessary, such warranties on behalf of BTE. 
  

 19 

 11.10 Modification of Product. The Parties acknowledge and agree that any modification to the Equipment or
Software other than by Vendor or its authorized service agents shall void the warranties provided by Vendor in Sections 11.1 through 11.4. 
 ARTICLE 12 — GENERAL TERMS AND CONDITIONS 
 12.1 Dispute Resolution. Subject to each party’s right to seek injunctive or
equitable relief in a court of competent jurisdiction, the parties agree to attempt to resolve all disputes under this Agreement in accordance with the dispute resolution procedures (“Dispute Procedures”) set forth herein. The parties
shall first attempt to resolve a dispute within ten (10) days through meetings between the respective Project Managers and any other representatives deemed necessary for these discussions. If unsuccessful, the parties agree to conduct
face-to-face negotiations between senior executive officers of both parties within a period of fifteen (15) days. If unsuccessful, or if fifteen (15) calendar days have passed since the parties submitted the dispute to the senior executive
officers, the parties may jointly agree to submit the matter to mediation upon mutually agreeable terms. Such mediation shall be concluded no later than thirty (30) days following agreement to mediate the dispute. The parties agree to continue
performance of their respective obligations under this Agreement, to the extent possible, during the performance of the Dispute Procedures. 
 12.2
Insurance. Upon execution of this Agreement, Vendor shall procure and thereafter maintain, with insurers reasonably acceptable to BTE, insurance protecting Vendor and BTE against liability from damages because of injuries, including death,
suffered by persons, including employees of BTE, and liability from damages to property arising from or growing out of Vendor’s operations in connection with the performance of this Agreement. Vendor represents to BTE that such insurance is,
and will be during the Term, no less in coverage than as set forth on Exhibit 12.2, Insurance Coverage. Vendor shall provide certificates evidencing such insurance prior to beginning delivery of any Products or performing any Services on a
form reasonably required by BTE. BTE and any other parties reasonably requested by BTE shall be listed as additional insureds under the relevant liability policies, and Vendor shall cause its insurance carrier to waive all rights of subrogation
against BTE on the policies listed above. Vendor shall require all authorized subcontractors to carry insurance coverage similar to that described above. 
 12.3 Participation by Affiliates. Vendor or any Affiliate of Vendor shall sell, deliver, install, and test, as applicable, the Products requested by Procurement Document submitted by BTE or any Affiliate of BTE. Accordingly,
references to BTE and to Vendor in this Agreement shall include the parties’ respective Affiliates, as applicable and where the context so requires. Notwithstanding the generality of the foregoing, Products purchased by an Affiliate of BTE
shall be included in the calculation of all discounts for which BTE and its Affiliates are eligible. 
 12.4 Compliance with Laws. Both parties shall
comply with all applicable laws, ordinances, rules, regulations and orders issued by any public or governmental agency, body or authority, whether international, national, local or otherwise. 
 12.5 Assignment. Neither party may, without the other party’s prior written approval (which shall not be unreasonably withheld, conditioned or delayed),
voluntarily or involuntarily assign, convey, transfer, pledge, mortgage or otherwise encumber all or any portion of its interests in this Agreement except to a party controlling, controlled by or under common control with such party; provided, BTE
may transfer and assign its interests in this Agreement (including the license to the Licensed Software) to any Affiliate, with the prior written approval of Infinera, which approval shall not be unreasonably withheld, and BTE may sell or resell the
Equipment provided hereunder, in whole or in part, to any other entity only to the extent that BTE shall no longer be utilizing such Equipment and only following BTE’s use of the Equipment for a minimum of one year. Vendor agrees that in the
event of an assignment of this Agreement, including an assignment by operation of law pursuant to a merger, change of control, or otherwise, that the assignee shall be required to assume all terms and conditions of this 

  

 20 

 
Agreement and that Vendor shall not be entitled to assign the Agreement without the written acknowledgement of the assignee to this condition. Further,
neither Vendor nor its assignee shall have the right to terminate this Agreement for convenience and any attempt by Vendor to terminate this Agreement prior to the end of the Term shall allow BTE to seek immediate relief and specific performance of
the Agreement by Vendor or its assignee, as applicable.

generality of the forgoing, neither party shall disclose (i) the terms and conditions of this Agreement or any Statement of Work, or (ii) the existence of the Project or any contractual relationship between BTE and Vendor, or

whole and in accordance with its fair meaning and not strictly for or against any party. The parties hereto acknowledge and agree that this Agreement has been negotiated by the parties and has been the subject of arm’s length and careful
negotiation over a considerable period of time, that each party has been given the opportunity to independently review this Agreement with legal counsel, and that each party has the requisite experience and sophistication to understand, interpret

it. 
 12.13 Enforcement. If any term or provision of this Agreement, the deletion of which would not adversely affect the receipt of any material
benefit by either party hereunder, shall be held by a court of competent jurisdiction to be invalid or unenforceable, the remainder of this Agreement shall not be affected thereby and each other term and provision of this Agreement shall be valid
and enforceable to the fullest extent permitted by law. It is the intention of the parties to this Agreement, and the parties hereto agree, that in lieu of each clause or provision of this Agreement that is illegal, invalid or unenforceable, the
court shall supply as a part of this Agreement an enforceable clause or provision as similar in terms to such illegal, invalid or unenforceable clause or provision as may be possible.

 EXHIBIT 4.2 —TRAVEL AND OUT-OF-POCKET EXPENSE POLICY 
 1. Introduction 
 Travel and
related expenses represent a significant controllable expense with respect to the operations of BTE Equipment, LLC (“BTE”). If and as authorized in the applicable master agreement between the parties (the “Agreement”), this
Travel And Out-Of-Pocket Expense Policy (the “Policy”) shall serve as the basis for reimbursement of reasonable expenses incurred by Vendor employees in the performance of Services for BTE. Exceptions to this Policy must be approved in
writing by the authorized BTE manager in advance of incurring the expense. BTE reserves the right to revise this Policy from time to time. 
 2. Definitions 
 For purposes of this Policy, the following definitions apply: 
 (1) “Assignment” means the length of time an individual is required to work at a BTE site. Use of individual(s) on concurrent
tasks/subcontracts shall be considered as one assignment if a break of less than two weeks occurs. Replacement of individuals based on personal or business requirements shall be interpreted as though the same individual was assigned. Example:
Employee A fills a Services requirement for 45 days. Employee B replaces A and performs an additional 50 days. Total of this assignment is 95 days. As an exception, when an employee resignation occurs which is outside the control of Vendor, the
replacement employee may be treated as starting a new assignment. 
 (2) “Local Employee” means an employee whose
residence or Primary Work Site is within a radius of 85 miles of a BTE site. 
 (3) “Travel Expenses” means actual
costs for lodging, meals and incidental expenses. 
 (4) “Primary Work Site” means the place where the majority of
the employee’s work time is spent, or the place where the employee returns during working hours upon completions of special assignments1. 
 (5) “Days” means calendar days. 
 3. Applicability 
 Reimbursement for Travel Expenses, as contained herein, shall be made for those designated and authorized employees of Vendor performing Services who are
non-Local Employees during the period of their Assignment to perform Services. Vendor shall pay for all Travel Expenses, subject to reimbursement by BTE in accordance with the Agreement and this Policy. Travel Expenses incurred outside of the scope
of the Vendor employee’s Services will be denied. This includes, but is not limited to, Travel Expenses incurred: 
  

	 	(i)	Prior to the execution of the Agreement (unless otherwise approved in writing); 

  

	 	(ii)	After termination of the Agreement or applicable Statement of Work; 

  

	 	(iii)	At a location not included in the Agreement of applicable Statement of Work; 

  

	 	(iv)	During the Term of the Agreement, but not authorized by the BTE manager, if such prior authorization is required; 

  

	 	(v)	Travel Expenses in excess of those allowed under this Policy; 

  

	 	(vi)	Travel Expenses incurred for reasons not directly related to the Services. 

  

 51 

 Only those Travel Expenses which are ordinary and necessary to accomplish the purpose of the business
trip are eligible for reimbursement. Entertainment expenses, including alcohol, are not reimbursable. Income and other taxes related to the services provided by Vendor’s employee are not eligible for reimbursement. Vendor will be responsible
for all unapproved Travel Expenses. 
 At the request of BTE, Vendors shall certify, in writing, the place of residence for any Vendor
employee. Completed certifications shall be submitted to BTE and Vendor shall maintain a copy of the certification. 
 IF REQUESTED, BTE
WILL NOT REIMBURSE TRAVEL RELATED EXPENSES UNTIL A PROPERLY EXECUTED CERTIFICATE OF RESIDENCE IS PROVIDED. 
 4. Lodging, Meal and
Incidental Expenses 
 (A) For travel to a BTE site within the continental 48 United States: 
 (i) For assignments of 90 days or less, costs incurred for Travel Expenses shall be reimbursed only to the extent that they do not exceed,
on a daily basis, the maximum established in the General Services Administration Federal Travel Regulation Maximum Per Diem Rates for travel in the continental 48 United States (http://policyworks.gov/org/main/mt/homepage/mtt/perdiem/perd02d.html).
The daily Travel Expense allowance is for lodging, meals and all fees and tips to waiters, porters, baggage handlers, and other hotel employees. Expenses for entertainment and personal convenience items such as alcohol, in-room movies, reading
material and clothing are not reimbursed. Vendor shall not “host” dinners or events for BTE employees and thereafter seek reimbursement from BTE. “Hosting” costs shall be Vendor’s responsibility. 
 (ii) Local Employees of Vendor are not entitled to reimbursement for Travel Expenses. 
 (iii) Travel Expenses covering any vacation period(s) taken in conjunction with travel (including weekends or holidays taken in
conjunction with vacation), and the periods covering return trips to the employee’s place of residence or Primary Work Site, are not reimbursable. 
 (B) Costs incurred for Travel Expenses for destinations outside of the continental 48 United States shall be reimbursed only to the extent that they do not exceed, on a daily basis, the maximum per diem rates in

mileage (back and forth to work) shall not be compensated. 
 8. Return Trips to Residence 
 For assignments of forty-five (45) days or longer, each Vendor employee is entitled to receive reimbursement for travel costs covering a trip to
their residence. Reimbursement shall be limited to payment for one trip every 30 days and to transportation costs only. The initial return trip shall not be made until the employee has been at the assignment for at least 25 days, unless authorized
by BTE in advance. 
 9. Receipts/Itemizing Expenditures 
 Travel expense accounts shall be submitted, with copies of all receipts for expenses over $25.00, itemizing expenditures for which

	5.2	Service Escalation Procedures. 

 5.2.1 Defect
Severity Levels. Defects (classified as Catastrophic, Critical, Major, or Minor defects) for all Products are defined in this Section. The classification and reclassification of the defect level shall be at the reasonable discretion of BTE;
provided, however, that such classifications and reclassifications shall be in accordance with the definitions set forth in this Section. In the event a defect is reclassified to a higher severity level by BTE, the Service Restoration time period
shall begin at the time the defect is reclassified. 
 (a) Catastrophic Defects. “Catastrophic Defects”
means conditions under which the Product is inoperative and BTE’s inability to use the Product creates an emergency situation with respect to BTE’s business operations. This condition generally is characterized by a loss of network
connectivity or service affecting a major customer or multiple other customers due to Product failure and requires immediate restoration or correction. 
  

 57 

 (b) Critical Defects. “Critical Defects” means conditions under
which the Product is partially inoperative, still usable by BTE, but creates a critical situation with respect to BTE’s business operations. The inoperative portion of the Product severely restricts BTE’s operations. 
 (c) Major Defects. “Major Defects” means conditions under which the Product is usable by BTE, with limited
functions, but creates a manageable situation with respect to BTE’s business operations. The condition is not critical to overall BTE operations and does not severely restrict such operations. 
 (d) Minor Defects. “Minor Defects” means conditions under which the Product is usable and the condition does not
adversely affect BTE’s operations. These problems are those resulting in a minor failure that is cosmetic or de minimis in nature. 
 5.2.2 Initial Response; Service Restoration; Defect Resolution. With respect to the terms utilized in the table below, the following definitions shall apply: 
 “Defect Resolution” is the time elapsed from BTE’s report of a defect to the time Vendor provides a final correction or modification
of the Product that corrects the root cause of the defect. 
 “Initial Response” means the time it takes from BTE’s
initial report of the defect until BTE speaks with the appropriate Vendor subject matter expert as set forth in the escalation table under Section 5.2.3 herein. The measurement of Initial Response time does not apply when a BTE call is related
to a previously reported defect. 
 “Service Restoration” means the time it takes Vendor to apply a functional resolution to
the reported defect, meaning Vendor provides BTE with a temporary fix or workaround that solves a reported defect and that can be used by BTE with minimal inconvenience and minimal impact on BTE’s business operations. 
 Vendor shall exercise its best, continuous and uninterrupted efforts, twenty-four (24) hours a day, seven (7) days a week, to achieve Service
Restoration for any Catastrophic Defects and Critical Defects as soon as possible after reported by BTE with a quarterly non-binding target of mean time to restore of one (1) hour. Without limiting the generality of the foregoing, the parties
agree that the time frames for Initial Response, Service Restoration and Defect Resolution set forth in the following table represent the outside time limit for Initial Response, Service Restoration and Defect Resolution and that BTE expects Vendor
to achieve time frames that are better than the time frames set forth below.

 [**] – Confidential treatment has been requested for the bracketed portions. The confidential redacted portion has been omitted and filed separately with the Securities and Exchange Commission. 

 5.2.3 Escalation of Unresolved Defects Within Vendor. For all defects reported by BTE, BTE shall
have the right to require Vendor to escalate BTE’s defect to the next appropriate tier in the applicable Vendor support organization. Such escalation is not intended to and shall not diminish Vendor’s obligations to restore and resolve
defects within the applicable time frames. In addition, Vendor shall observe the following management notification procedures with respect to all unrestored Catastrophic Defects and Critical Defects: 
 (a) Service Interruption. Upon BTE’s report to Vendor of the existence of a Catastrophic Defect, Vendor shall notify Vendor’s Tier
3 Support via a Vendor technical support engineer and any additional Vendor personnel as needed by Product. If Service Restoration with respect to a Catastrophic Defect has not been achieved within thirty (30) minutes after the defect is
reported by BTE to a Vendor technical support manager, as applicable, Vendor shall notify the appropriate Vendor supervisory management of the unrestored condition. If Service Restoration has not been achieved within one (1) hour after the
defect is reported, the next higher level of Vendor supervisory management shall be notified of the unresolved condition. 
 (b)
Extended Service Interruption. Upon the occurrence of an Catastrophic Defect that: (i) affects multiple customers and Service Restoration has not been achieved within thirty (30) minutes following BTE’s report to Vendor of
such Catastrophic Defect; or (ii) affects special facilities, such as 911, governmental facilities, military, commercial airports, etc.; or (iii) includes media involvement (an “Extended Service Interruption” or
“ESI”), then in addition to the Vendor personnel identified in subsection (a) above, Vendor shall notify Vendor’s Vice President of Service and Support and the Vice President of Hardware Engineering or Vice
President of Software Engineering, depending on the nature of the defect, as applicable. Such notification shall be made by means of Vendor’s call center via telephone, facsimile or e-mail commencing within sixty (60) minutes following
BTE’s report to Vendor of the Catastrophic Defect and concluding within thirty (30) minutes thereafter. 
 (c) Critical
Defects. If Service Restoration with respect to a Critical Defect has not been achieved within one (1) hour after the defect is reported by BTE to Vice President of Operations, as applicable, Vendor shall notify the
appropriate Vendor supervisory management of the unrestored condition. 
 Technical and management escalation contact information for the persons set forth
in this Section are as follows:

Vendor shall provide to BTE a report that summarizes the percentage of defects responded to, restored and resolved within the time frames specified in this Section 5.2. 
  

 59 
 [**] – Confidential treatment has been requested for the bracketed portions. The confidential redacted portion has been omitted and filed separately with the Securities and Exchange Commission. 

 5.2.5 Reviews. As part of its ongoing Maintenance and Support Services, Vendor shall
provide the following: 
 (a) Operational reviews and service reports within mutually agreed to time frames (but no less than
quarterly), which reports shall include, without limitation: (i) a detailed summary and status of all defects reported by BTE; (ii) the number of remote accesses by Vendor into BTE’s systems; (iii) the number of Maintenance and
Support Services-related on-site visits; and (iv) Maintenance Releases sent and applied to Products; (v) analysis of hardware and Software release schedules, and (vi) an analysis of RMA requests and fulfillment of same by Vendor; and

 (b) Access to any performance evaluation or troubleshooting Software, tools or utilities that are generally available to
Vendor’s customers to aid BTE in monitoring Product usage and projecting resource needs.

 Vendor shall not be responsible, nor will liquidated damages apply, if a failure to meet the
Service Restoration response time for Catastrophic and Critical Defects is due to the Vendor’s operator error (including, without limitation, lack of fiber cleaning procedures, improper ESD procedures, non-supported hardware or software
configurations, unavailable spare parts unless caused by Vendor’s failure, unavailable BTE technicians to support remote inquiries, or inability to access a network element), or if such failure was due to a facility power issue, Force Majeure
or other item beyond the control of Vendor. The liquidated damages calculation shall exclude any amounts related to Products used by BTE for spares or Products that have not reached Acceptance. 
 BTE may elect to acquire liquidated damages through application of credit off future purchases or, at BTE’s option, through payment by Vendor in
immediately available funds. 
 5.2.7 Failure to Meet Return to Factory. [**] 
 [**] 
 5.2.8 MTBF. The parties agree
that if the mean time between failures (“MTBF”) measured on Vendor’s Equipment is less than the MTBF set forth in the Documentation (over a statistically relevant sample size of Vendor’s Equipment), BTE shall so notify Vendor
(“MTBF Notification”). Upon receipt of the MTBF Notification, Vendor shall promptly conduct a root cause analysis of the issue and shall take all appropriate remedies to rectify such deviation. [**]. 
 5.2.9 Information Requests. In the event Vendor requests any Software dumps, tapes, logs or any other documentation from BTE to resolve a reported
problem, such documentation shall be forwarded through electronic means (email or ftp) or by overnight courier at Vendor’s expense if electronic means are not available.
