Mavenir’s designated bank. Any amounts payable by Starent hereunder which remain unpaid after the due date shall be subject to a late charge equal to the lesser of 1.25% per month or the maximum rate allowed by law.

 5.5 Milestone Invoicing; Holdbacks. 

(a) With respect to any purchase order, or portion thereof, that designates fees to be paid on a milestone basis, Mavenir may invoice
Starent for the amount set forth as the “Amount” to be invoiced in connection with the applicable “Milestone” upon the occurrence of the “Milestone” (provided that all prior events listed as milestones have previously
occurred). 
 (b) With respect to any purchase order, or portion thereof, that designates fees to be paid on a holdback basis,
Mavenir may invoice Starent for 80% of the total amount when due and payable in accordance with the purchase order and may invoice Starent for the aggregate balance of such amounts upon satisfactory completion and Starent’s Acceptance of the
Mavenir Products or Mavenir Services. 
 (c) All amounts payable under this Agreement are exclusive of tax. Starent shall pay
any taxes, including sales, use, personal property, value-added, excise, customs fees, import duties or stamp duties or other taxes and duties imposed by governmental agencies of whatever kind and imposed with respect to all transactions under this
Agreement including penalties and interest but specifically excluding any income taxes payable by Mavenir. 
 5.6 Starent shall
maintain accurate and complete records relating to its activities under this Agreement sufficient for Mavenir to determine Starent’s compliance with the provisions of this Section 5, and shall retain such records for a period of
three years after the calendar year in which such activities related. Mavenir shall have the right (not more than once per calendar year), on its own or using an independent auditor or agent, upon thirty (30) days’ prior written notice to
Starent, to inspect, during normal business hours and at mutually agreeable times, Starent’s records to verify compliance by Starent with the terms of this Section 5. Starent agrees to cooperate reasonably with Mavenir in any such
inspection. 
 5.7 Prompt Invoicing. Mavenir must not (a) invoice Starent more than ninety (90) days after
Mavenir is permitted to issue an invoice under this Agreement (“Late Invoices”) or (b) initially raise a claim for payment under a previously issued invoice more than 365 days after the invoice date (“Late Claims”). Starent
is not obligated to pay Late Invoices or Late Claims and Mavenir waives all rights and remedies related to Late Invoices and Late Claims. 
 5.8 Delivery. Starent shall from time to time place written purchase orders for Mavenir Products under this Agreement. Orders shall specify the quantity of Mavenir Products to be delivered,
delivery destination, and a requested shipment date. Mavenir shall ship all Mavenir Products in accordance with the lead-time or delivery date that is set forth on a purchase order and accepted by Mavenir, provided that, in no event shall any
lead-time less than twelve (12) weeks before the requested customer delivery dates be effective under any purchase order unless accepted in writing by Mavenir. If Mavenir accepts the purchase order but is unable to ship the Mavenir Products by
the agreed upon shipment date, and such delay results in Starent paying damages to an End User or Distributor, then Mavenir shall reimburse Starent for such damages to the extent specifically caused by Mavenir’s delay, such damages not to
exceed the delay damages set forth in 

  

			
	 Confidential and Proprietary
	 	Page 12

 
Starent’s agreement with its End User or Distributor. At Starent’s option, such credit shall be paid in cash or applied against future purchases and reflected in future invoices.
Mavenir shall accept or reject each purchase order submitted by Starent within five (5) business days of Mavenir’s receipt of such purchase order. If Mavenir does not reject an order within five (5) business days of receipt, the order
will be deemed accepted. If Mavenir is more than 30 days late in shipping any Deliverables specified in the applicable purchase order, Starent may, without liability, terminate any undelivered portion of the purchase order and any other undelivered
purchase orders for the same or substantially similar Deliverables. Starent’s acceptance of all or any part of the Deliverables does not waive any claim that Starent may have for delay damages under this Section. 

5.9 Shipping Terms. All deliveries under this Agreement shall be FCA Mavenir’s facility (Incoterms 2000). Title to all
Mavenir Products will pass to Starent upon delivery. In the absence of specific shipping instructions from Starent, Mavenir will select a common and/or freight forwarder carrier. Mavenir will ship Mavenir Products to the location specified in the
applicable purchase order using the method of shipping and the carrier specified in the applicable purchase order. In the absence of written shipping directions, Mavenir will select the carrier and insurance that is consistent with the Parties’
past practice, using Mavenir’s reasonable commercial efforts. All shipments will be identified with large, easily readable type, including the shipping location, the purchase order number, and any other special purchase or shipping instructions
required by Starent. Mavenir may not ship partial orders of Mavenir Products without Starent’s prior written consent. 

5.10 Issuance of Warrant. Upon execution of this Agreement, Mavenir shall execute and deliver to Starent the Warrant. Mavenir
represents that it has reserved a sufficient number of shares of its Series C Convertible Preferred Stock (“Series C Shares”) to permit the full exercise of the Warrant, and agrees to maintain during the term of the Warrant a sufficient
number of Series C Shares to permit exercise of the Warrant in accordance with its terms. 
 5.11 No Volume Commitment.
This Agreement does not commit Starent to purchase any Mavenir Product or Mavenir Services. Starent’s issuance of a purchase order referencing this Agreement is Starent’s agreement to pay for Mavenir Products or Mavenir Services.

 6. ACCEPTANCE, ROADMAP, DEVELOPMENT, SUPPORT 
 6.1 Acceptance. Acceptance of Deliverables will occur after Starent or Starent’s End User or Distributor submits to Mavenir a written, signed certificate confirming the Deliverables conform with the
Acceptance Criteria (“Acceptance”). Starent shall provide prompt notification to Mavenir of any acceptance by an End User or Distributor pursuant to the terms of such End User or Distributor agreement within five (5) days of receipt
of such acceptance. If Starent or its End User notifies Mavenir that the Deliverable does not meet the Acceptance Criteria, Mavenir will promptly investigate the alleged nonconformity and will correct such nonconformity within five (5) business
days (or as otherwise reasonably required given the nature of the nonconformity). Upon Mavenir’s notice to Starent that Mavenir has cured such nonconformity, Starent or Starent’s End User or Distributor will
re-test the defective Deliverable. If the Deliverable again fails the applicable Acceptance Criteria, Starent or Starent’s End User or Distributor may return the rejected Deliverables to Mavenir and may
suspend or cancel any existing or future purchase orders for the same or similar Deliverables which has not passed Acceptance or which is dependent on another Mavenir Product that has not passed Acceptance, and obtain replacement deliverable(s) from
third parties at Mavenir’s expense.

 6.2 Mavenir’s Roadmap; Changes to Specifications. Mavenir will provide Starent
with Mavenir’s product roadmap, as updated from time to time by Mavenir. In addition, Mavenir may not materially modify Deliverables that Starent has already purchased or licensed under this Agreement in such a way that will materially
adversely affect functionality or performance of such Deliverables without at least ninety (90) days’ prior written notice to Starent. Examples of such material modifications include: (i) modifying the operation of the Deliverables
from the level of performance set forth in any specification; (ii) affecting the performance or functionality of Deliverables; and (iii) engineering changes that affect installation or configuration of the Deliverables. 

6.3 Replacement Parts. Mavenir will continue to manufacture or otherwise provide replacement parts to support any Deliverable
purchased by Starent for at least five (5) years after the end of life of any Mavenir Product. Mavenir will provide Starent with at least twelve (12) months’ advanced written notice of the issuance of any end of life notice for any
Mavenir Product. 
 6.4 Chronic Conditions 
 (a) Definition. A Deliverable is considered “chronically defective” when a documented, repetitive defect occurs more than three (3) times over thirty (30) days in any single
unit of Deliverable, or when a documented, repetitive defect occurs in multiple units of a Deliverable when those units represent more than 25% of the existing field population in a given metropolitan area of such Deliverables distributed by
Starent, which is attributable to a failure of the Deliverable to perform in accordance with its specifications. Starent will provide reasonable documentation to support its final decision on the existence of a chronic condition. 

(b) Remedies. If Starent determines that a Deliverable is chronically defective and Starent provides Mavenir with written notice
of such status, Mavenir will submit to Starent a remedial plan within five (5) business days of receiving Starent’s chronic condition notice. Starent will review and approve or disapprove the plan within 5 days. If Starent accepts the
plan, Mavenir will accept return of all chronically defective Deliverables and replace the chronically defective Deliverables according to the approved plan. If Starent does not accept the plan, in exchange for the returned Deliverables, Mavenir
shall provide Starent with equivalent replacement Deliverables, which resolves the chronically defective Deliverables, at [***]. 
 6.5 Malicious Technology. Mavenir warrants that at the time of delivery the Deliverables will not: (i) contain any Malicious Technology, (ii) contain any files or features that will
disable or destroy any functionality of the Deliverables, (iii) monitor any use of the Deliverables; (iv) replicate, transmit or activate itself without control of a person operating the computing equipment on which it resides; or
(v) alter, damage or erase any data or computer programs without control of a person operating the computing equipment on which it resides. If Mavenir is in breach of this subsection, no “right to cure” period will apply. Starent
reserves the right to pursue any available civil or criminal action against Mavenir for violation of this provision. Mavenir acknowledges that it does not have any right to electronically repossess or use any electronic self-help related to the
Deliverables.

 6.6 Compatibility. Mavenir warrants that its Software will be backwards compatible to
N-2 major releases to the current release, where “N-2” refers to the number to the left of the decimal point of the software release. For example, a current
software release will be backwards compatible with the prior two (2) major releases. 
 6.7 Development. 

(a) Mavenir agrees to develop certain solutions (collectively, the “Solutions”) for Starent as set forth in the Statement of
Work (the “SOW”) attached hereto as Appendix G. The Parties agree that the timely development of the Solutions is critical to the success of the Parties’ relationship and their go-to-market strategies, and that Starent considers the timely development of the Solutions as core to its decision to invest in Mavenir and to enter into this Agreement with Mavenir. As a result, the Parties
have agreed to establish a total of three milestones in connection with the development of the Solutions, as more fully set forth in the SOW (each, a “Milestone” and collectively, the “Milestones”). Each Milestone shall be
completed on or before the date set forth in the SOW with respect to such Milestone (each, a “Milestone Date”), except as otherwise set forth herein. In the event that Starent believes that any Milestone will not be achieved due to
circumstances that are beyond the reasonable control of Mavenir, then the Parties will negotiate a reasonable, extended Milestone Date for such Milestone. To assure prompt performance of the Milestones, the Parties have agreed that Mavenir shall be
subject to liquidated damages in the aggregate amount of up to $[***] (US) (the “Liquidated Damages”), which amount shall be divided evenly among the three Milestones as set forth in the SOW. Accordingly, the Parties agree that, in the
event Mavenir fails to achieve any Milestone and Mavenir fails to cure such failure on or before the expiration of the applicable Milestone Cure Period (defined below), Mavenir shall pay to Starent in cash, immediately upon the expiration of the
applicable Milestone Cure Period, the applicable Liquidated Damage set forth in the SOW which corresponds to the milestone for which Mavenir is the cause of the failure to achieve. The aggregate Liquidated Damages are payable in full to Starent
notwithstanding any limitation of liability provision set forth in Section 13. The “Milestone Cure Period” shall commence upon Mavenir’s receipt of written notice from Starent of any alleged missed milestone, and
(a) with respect to the Milestone 1, shall be for a period of ninety (90) days, and (b) with respect to Milestones 2 and 3, shall be for a period of thirty (30) days. If any Milestone Cure Period shall expire without Mavenir
having cured its failure to achieve such milestone, Starent shall not be required to provide Mavenir with any demand or notice of any nature whatsoever in connection with the assessment, payment or collection of any Liquidated Damage. The Parties
agree that damages incurred by Starent resulting from any uncured delay would be substantial and difficult to ascertain, and that the Liquidated Damages provide a reasonable and agreed-upon estimate of such damages. In no event shall Mavenir be
liable for any Liquidated Damages if the failure to achieve any Milestone or cure any such failure within the applicable Milestone Cure Period for such Milestone is primarily caused by or attributable to a party other than Mavenir. 

(b) In the event that the Milestone Date for any Milestone is extended to a date more than three (3) years following the date of
this Agreement for any reason, then the Liquidated Damages potentially payable by Mavenir with respect to the failure to achieve such Milestone on or before its Milestone Date shall terminate as of the close of business on the third anniversary of
the date of this Agreement and Mavenir shall no longer be subject to Liquidated Damages with respect to that Milestone.

 6.8 Business Reviews. Starent may request that quarterly business reviews be held
between Starent and Mavenir to review delivery performance, quality metrics, or any other relevant information related to the performance of Mavenir. Additionally, Starent may request that Mavenir provide regular reports regarding delivery
performance, quality metrics, or other relevant information if deemed necessary by Starent. 
 7. CO-MARKETING/PRE-SALES COOPERATION 
 7.1 The Parties will work together to mutually
prioritize target customers, define sales engagement models and outline specific roles and responsibilities of the respective organizations involved in promoting the Mavenir Products in conjunction with use of the Starent Product. 

7.2 The Parties will work together to mutually develop marketing strategies and customer value propositions for the Mavenir Products by
Starent in conjunction with the Starent Product. 
 7.3 During any exclusivity period pursuant to Section 2.7 with respect
to the sale of Mavenir Products to a customer or potential customer, Starent shall drive all interactions with, and be the sole contact with, such customer or potential customer. Starent shall drive all interactions with, and be the sole contact
with, Starent’s customers, prospective customers and partners, including, without limitation, the Starent House Account Customers set forth on Appendix E, with respect to the sale of Starent Product. Mavenir will support Starent’s
efforts as requested by Starent from time to time in connection therewith, and in connection with any bid and proposal in which Starent intends to bid Mavenir Product, whether or not rebranded by Starent. Mavenir shall not make any statements,
representations or commitments of any kind on behalf of Starent with any third party, including, without limitation, any Starent House Account Customer or any other existing or potential customer. 

7.4 During the term of this Agreement and for a period of one year following termination of or expiration of this Agreement, Mavenir
shall not compete with Starent with respect to the CDMA Femto Solution within the Territory; provided, however, that the Parties agree that Mavenir may continue its existing business relationship with Motorola solely with respect to the RFP issued
by Sprint for a Femto solution, and not other business opportunity with Motoroal. Mavenir agrees to work with Starent as contemplated by this Section 7 in connection with each Starent House Account Customer identified in Appendix
E, as long as Starent has an existing contractual relationship with such customer. 
 7.5 Starent and Mavenir will conduct
regular review of progress with such customers. Mavenir agrees to work with Starent in all markets within the Territory. 
 7.6
The Parties’ collaboration obligations under this Agreement are non-exclusive and, except as and solely to the extent expressly set forth in Section 2.7, and except with respect to each
Party’s confidentiality obligations regarding the use of the other party’s Confidential

collaborates on any of the foregoing.

to Mavenir’s Intellectual Property or products, except as expressly set forth in this Agreement. Starent shall own the Intellectual Property associated with any improvements or modifications to the Mavenir Products made by Starent (the
“Starent Modifications”) to the extent and only to the extent that such Intellectual Property does not incorporate any Mavenir Products or Mavenir Intellectual Property. To be clear, Starent shall not own nor have any ownership rights in
any Mavenir Products, Mavenir Intellectual Property or any improvements or modifications to the Mavenir Products solely made by Mavenir. Furthermore, Mavenir shall have a perpetual, nonexclusive, fully transferable, sublicensable, royalty-free,

Property or any improvements or modifications to the Starent Products solely made by Starent. Furthermore, Starent shall have a perpetual, nonexclusive, fully transferable, sublicensable, royalty-free, worldwide license to use, disclose, reproduce,

 9. CONFIDENTIALITY 

9.1 Confidentiality Obligation. Each of Starent and Mavenir in the capacity of receiving information from the other Party (the
“Receiving Party”) shall keep strictly confidential any information disclosed in writing, orally or in any other manner by the other Party (the “Disclosing Party”) or otherwise made available to the Receiving Party concerning the
Disclosing Party’s performance of this Agreement or otherwise concerning pricing, the business, operations, Intellectual Property, trade secrets or other proprietary information of the Disclosing Party, provided that such written information is
marked as confidential or proprietary and such oral information is identified as confidential or proprietary at or within three (3) days after the time of disclosure (“Confidential Information”), using at least the same degree of care
that it uses to protect its own confidential or proprietary information but in no event less than reasonable care for the telecommunications software industry. “Confidential Information” shall not include information: 

(a) which is or becomes generally available to the public other than as a result of disclosure thereof by the Receiving Party in
violation of this Section 9; 
 (b) which is lawfully received by the Receiving Party on a non-confidential basis from a third party that is not itself under any obligation of confidentiality or nondisclosure to the Disclosing Party with respect to such information; 

(c) which by written evidence can be shown by the Receiving Party to have been independently developed by the Receiving Party; or

 (d) which was in the Receiving Party’s possession at the time of disclosure by the Disclosing Party. 

9.2 Nondisclosure of Confidential Information. The Receiving Party shall use Confidential Information solely for the purposes of
this Agreement and shall not disclose or disseminate any Confidential Information to any Person at any time, except for disclosure to those of its directors, officers, employees, accountants, attorneys, advisers and agents whose duties reasonably
require them to have access to such Confidential Information, provided that such directors, officers, employees, accountants, attorneys, advisers and agents are required to maintain the confidentiality of such Confidential Information to the same
extent as if they were Parties hereto. 
 9.3 Independent Development/Use of Residuals. The terms of confidentiality
under this Section 9 shall not be construed to limit either the Disclosing Party or the Receiving Party’s right to independently develop or acquire products without use of the other party’s Confidential Information. Further,
the Receiving Party shall be free to use for any purpose the residuals resulting from access to or work with the Confidential Information of the Disclosing Party, provided that the Receiving Party shall not disclose the Confidential Information
except as expressly permitted pursuant to the terms of this Agreement. The term “residuals” means information in intangible form, which is retained in memory by persons who have had access to the Confidential Information, including ideas,
concepts, know-how or techniques contained herein. The Receiving Party shall not have any obligation to limit or restrict the assignment of such persons or to or to pay royalties for any work resulting from
the use of residuals. However, this Section 9.3 shall not be deemed to grant to the Receiving Party a license under the Disclosing Party’s copyrights or patents. 

9.4 Press Releases. No Party to this Agreement shall originate any publicity, news release or other public announcement, written
or oral, whether relating to this Agreement or any arrangement between the Parties, without the prior written consent of the other Party, except to the extent such publicity, news release or other public announcement is required by law; provided

  

			
	 Confidential and Proprietary
	 	Page 18

 
that in such event, the Party issuing same shall use its reasonable efforts to secure confidential treatment of such information in consultation with the other Party prior to its disclosure or
filing and disclose only the minimum necessary to comply with such requirements, shall still be required to consult with the other Party or Parties named in such publicity, news release or public announcement a reasonable time (being not less than
48 hours) prior to its release to allow the named Party or Parties to comment on the use of its name and, after its release, shall provide the named Party or Parties with a copy thereof. Neither Party shall use the name of the other for advertising
or promotional claims without the prior written consent of the other Party. 
 9.5 Exception. The foregoing
confidentiality and nondisclosure obligations shall not prohibit the disclosure of Confidential Information, to the extent such disclosure is required by law or by regulation; provided, however, that, in such event, the Party required by law or by
regulation to provide such disclosure shall provide the other Party with prompt advance notice of such disclosure so that the other Party has the opportunity if it so desires to seek a protective order or other appropriate remedy and in such event
the Party required by law or by regulation to provide such disclosure shall use its reasonable efforts to secure confidential treatment of such information in consultation with the other Party prior to its disclosure or filing and disclose only the
minimum necessary to comply with such requirements. 
 9.6 Feedback. The Receiving Party may from time to time provide
suggestions, comments or other feedback (“Feedback”) to the Disclosing Party regarding the Disclosing Party’s products with respect to Confidential Information provided originally by the Disclosing Party. Both Parties agree that all
Feedback is and shall be given entirely voluntarily. Feedback, even if designated as confidential by the Party offering Feedback, shall not, absent a separate written agreement, create any confidentiality obligation for the receiver of the Feedback.
Furthermore, except as otherwise provided in a separate subsequent written agreement between the Parties, the receiver of the Feedback shall be free to use, disclose, reproduce, license or otherwise distribute, and exploit the Feedback provided to
it, royalty free, entirely without obligation or restriction of any kind on account of intellectual property rights or otherwise.

 10.1 Mutual Warranties. Each Party
represents and warrants to the other Party that:

Starent shall return the Deliverables to Mavenir, at Mavenir’s expense, for correction or replacement or credit, even if the period to perform those corrections extends beyond the Deliverables’ warranty period (provided that notice of such
warranty claim was provided to Mavenir prior to the end of the applicable warranty period). No remedy set forth in this Agreement (except to the extent specifically stated herein) is intended to be exclusive of any other remedy, and each remedy will
be in addition to every other remedy given hereunder, or now or hereafter existing at law, in equity, by statute, or otherwise. 

10.4 EXCEPT FOR THE EXPRESS WARRANTIES PROVIDED IN THIS SECTION, MAVENIR DISCLAIMS ALL OTHER WARRANTIES, EXPRESS, IMPLIED OR STATUTORY,
INCLUDING ALL IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. EXCEPT WITH RESPECT TO THE EXPRESS WARRANTIES PROVIDED BY MAVENIR UNDER THIS AGREEMENT, STARENT SHALL NOT MAKE ANY OTHER WARRANTY COMMITMENT, WHETHER WRITTEN

 11. INDEMNIFICATION 

11.1 Indemnity. 
 (a) Mavenir Indemnity. Mavenir agrees to indemnify, defend and hold harmless Starent and its Affiliates, officers, directors, employees, customers and agents from and against any and all third
party claims or actions of any kind whatsoever, arising directly or indirectly out of claims that the use, distribution, sublicensing, or sale of the Mavenir Products, the use of any Mavenir Trademarks, or the provision of Mavenir Services hereunder
infringes on a patent, trademark, trade name, copyright or other intellectual property right of a third party or constitutes a misappropriation of the trade secrets of a third party. Such indemnity shall extend to the payment of any final award of
damages assessed against Starent resulting from such claim or action or any settlement amount agreed to by Mavenir, as well as any costs and attorneys’ fees reasonably incurred by Starent. Such obligations are subject to Starent providing
Mavenir with prompt written notice of any such claim; Mavenir having sole control and authority with respect to the defense and settlement of any such claim; and Starent cooperating fully with Mavenir, at Mavenir’s sole cost and expense, in the
defense of any such claim. Mavenir shall not agree to any settlement of any such claim that does not include a complete release of Starent from all liability with respect thereto or that imposes any liability, obligation or restriction on Starent
with the prior written consent of Starent. Starent may participate in the defense of any claim through its own counsel, and at its own expense. 
 (b) General Indemnity. Each Party agrees to indemnify, defend, and hold harmless the other Party and its Affiliates, officers, directors, employees, and agents from and against any and all third
party claims or actions of any kind whatsoever, arising directly or indirectly from such Party’s intentional or grossly negligent actions. 
 11.2 Procedure. In the event that the use, distribution, sublicensing, or sale of any Mavenir Product infringes on the a patent, copyright or other intellectual property right of a third party or
constitutes a misappropriation of the trade secrets of a third party or if Mavenir reasonably believes that the use, distribution, sublicensing, or sale of any Mavenir Product may constitute such an infringement or a misappropriation, Mavenir shall,
at its sole cost and expense, and at its option, either (i) procure for Starent and its Distributors and End Users the right to continue to exercise its rights to such Mavenir Product hereunder, (ii) modify such Mavenir Product so that it
becomes non-infringing or no longer constitutes a misappropriation, without diminishing the functionality or performance of such Mavenir Product; provided, however, that if (i) and (ii) are not reasonably possible, then
Mavenir shall have the right to terminate this Agreement by giving Starent sixty (60) days prior written notice and providing a refund of all amounts paid by Starent for such infringing Mavenir Product and all less depreciation for use assuming
straight line depreciation over a period of five (5) years commencing upon delivery of the applicable Mavenir Product. Nothing in this Section 11 shall enable Mavenir to terminate a license of a Mavenir Product to any End User.

 11.3 Exclusions. Mavenir shall have no obligation for any claim of infringement to the extent arising from:
(i) any combination of a Mavenir Product with products not supplied by Mavenir, where such infringement would not have occurred but for such combination; (ii) the adaptation or modification of a Mavenir Product by Starent or any third
party, where such infringement would not have occurred but for such adaptation or modification; (iii) a claim based on a Starent Product or intellectual property rights owned by Starent; (iv) use of any Mavenir Products in a manner not
strictly in accordance with this Agreement; (v) Mavenir’s modification of any Mavenir Products in compliance with Starent’s designs or specifications, provided that such designs

  

			
	 Confidential and Proprietary
	 	Page 21

 
or specifications did not allow for a non-infringing alternative; or (vi) use of other than Mavenir’s most current release of the Mavenir
Products provided to Starent at no charge if the claim or action would have been avoided by use of the most current release. Starent will defend, or at its option settle, and indemnify Mavenir for any claims brought against Mavenir referred to in
clause (iii) of this subsection in the same manner as provided above. 
 11.4 THE FOREGOING STATES THE PARTIES’
SOLE OBLIGATIONS AND EXCLUSIVE REMEDIES FOR INTELLECTUAL PROPERTY RIGHTS INFRINGEMENT. 
 12. ESCROW 

12.1 Starent, as Beneficiary, and Mavenir, as Depositor, each hereby agrees to enter into the Escrow Agreement on the Effective Date,

 Delay penalties shall accrue at [***] of the net price of the delayed product if the delay is caused by
Mavenir. 
 Unless required by an End User, liquidated damages shall not be cumulative. 

 

	3.7	Flow Down Provisions; Non-Standard Service Level Agreements. Notwithstanding anything to the contrary herein, with respect to
sales made to accounts other than T-Mobile, if requested by the applicable customer and as long as the aggregate service level agreement and related liquidated damages that may be assessed against Starent and
flowed down to Mavenir are substantially the same or less stringent in the aggregate than those stated above, and other flow-down terms are substantially the same or less stringent than the applicable remaining terms set forth in this Agreement,
Mavenir agrees to provide “back-to-back” maintenance and support for Mavenir Products sold to Starent or its customers on the same terms and conditions that
Starent has with each such customer, including, without limitation, warranty and “non-warranty” hardware and software support, service level agreements and the flow down of all related penalties which are directly attributable to
Mavenir’s maintenance and support obligations. For all T-Mobile sales and accounts, the minimum back-to-back standard terms
and conditions for maintenance and support and related liquidated damages are set forth in Exhibit C to the Master Agreement between T-Mobile USA, Inc. and Mavenir Systems dated March 24, 2008 (the
“SMS Offload Agreement”), a copy of which is attached hereto as Exhibit C-1, and the terms and conditions of his Agreement; provided, however, that the notice and cure provisions in Section 3.6
below shall be included in such back-to-back terms. In the event that Starent negotiates different terms and conditions with
T-Mobile USA that differ materially from those set forth in Exhibit C-1, then, upon request by Starent, Mavenir and Starent shall replace Exhibit C-1 with the service level agreement that Starent eventually negotiates with T-Mobile USA. 

 

	3.5	The parties agree to work together in good faith with respect to all flow down and
back-to-back terms and conditions for all accounts. 

  

	3.6	Starent shall provide Mavenir with written notice in the event that Mavenir materially breaches its maintenance and support obligations hereunder. Notwithstanding the
thirty (30) day cure period set forth in Section 14.1 of the Agreement, (a) in the event Mavenir is in material default of its Work Around or Resolution Time metrics in connection with a Critical Fault or a Major Fault, Mavenir
shall be entitled to a seven (7) calendar day cure period from the date of receipt of notice, and (b) in the event Mavenir is in material default of its Work Around or Resolution Time metrics in connection with a Minor Fault or Technical
Inquiry, Mavenir shall be entitled to a fifteen (15) calendar day cure period from the date of receipt of notice. Mavenir shall be deemed to be in material breach of it’s maintenance support obligations and this Agreement, for purposes of,
among other things, the Escrow Agreement if (a) Starent issues three distinct notices of cure to Mavenir within any thirty (30) day period, and (b) Mavenir fails to cure each such default within the applicable cure period for the
applicable notice.

 3.8. Documentation 

 

	3.8.1.	Supplier shall completely or partially adapt, revise or replace the Documentation periodically or provide T-Mobile with interim
release notes if such should be reasonably necessitated by the provision of new or improved versions or corrections of the Software. Documentation or release notes shall be provided electronically and as a hard copy. 

3.9. Service Uptime or Availability 
  

	 	3.9.1.  	The service uptime or availability will be measured as from a Geo-redundant and distributed System by the availability of
  the Services provided to all Subscribers of T-Mobile, based on following: 

  

	 	a.	During any period in which one System component, whether it is a single node or a blade component, is unavailable but the other System component(s) is or are working
properly and there is no negative impact to overall System operation and Service, the availability of the Services provided to T-Mobile’s Subscribers shall be considered to be 100% (hundred percent).

  

	 	b.	During any period in which a System, or a System site, is unavailable but T-Mobile is able to
re-route the affected traffic to another System or another Geo-diverse System site without causing any negative impact to the overall System operation, Service and or
business, the availability of the Services provided to T-Mobile’s Subscribers shall be considered to be 100% (hundred percent). If T-Mobile is unable to re-route such traffic or there is negative impact to overall System operation, Service and or business, then the availability shall be considered to be 0% (zero percent) during such period. 

 

	 	c.	Planned service outage approved by T-Mobile will not be included in calculating System unavailability. 

 

	3.9.2.	The unavailability time is the time from when T-Mobile notifies Supplier of an Incident until the time Supplier has successfully
implemented a Work around or Solution 

  

	3.9.3.	Downtime—As to any calendar month, Downtime is defined as the total amount of Unscheduled Downtime less Scheduled Downtime for Service due to negative
impact by the System during a calendar month. Downtime is expressed in minutes. Excluded from Downtime is any downtime caused by T-Mobile, Supplier, third parties, acts of force majeure, Network outages, or
caused by any circumstances beyond the reasonable control of T-Mobile. 

  

	3.9.4.	Scheduled Downtime—As to any calendar month, the amount of time scheduled by T-Mobile for planned maintenance
of the System. Scheduled Downtime is expressed in minutes. 

  

	3.9.5.	T-Mobile Unscheduled Downtime—As to any calendar month, any total or partial disruption or impairment in the Service
due to negative impact by the System which results in a Severity Level E1 or Severity Level E2 outage of the Service, not the result of Scheduled Downtime, expressed in minutes. 

 

	3.9.6.	Total Time Available—As to any calendar month, the product of one thousand four hundred and forty (1,440) and the total number of days in such month,
less Scheduled Downtime. Total Time Available is expressed in minutes. 

  

	3.9.7.	Service Uptime or Availability—As to any calendar month, the number one (1), minus the accumulated Unscheduled Downtime for such month divided by the Total
Time Available for such calendar month. Service Uptime or Availability is expressed as a percentage. 

  

	3.9.8.	Supplier will guarantee T-Mobile that Service Uptime or System Availability shall be 99.999%. 

  

					
	Service & Support Specification	  	Strictly Confidential Information	  	Page 16 of 20

	3.9.9.	If the Service uptime or availability is below the 99.999% in a calendar month, calculated using above method, this will result in a decrease of the quality of T-Mobile service. In this case, T-Mobile shall be entitled to charge a penalty of 30% of the prorated monthly Support Services fee for that relevant year on a per Incident
basis. 

 3.10. Performance Penalties 

 

	3.10.1.	If the Workaround as described in section 3.4, Incident Handling, is prolonged to an unacceptable extent by Supplier, this will result in a decrease of the quality of T-Mobile service. “No Workaround” or “non-neutralization” is defined as having no Final solution and/or Workaround. In this case, T-Mobile shall have the
right to receive liquidated damages from Supplier in accordance with the following chart on a per Incident basis:

corresponding to such Milestone. 
 (b) The purchase rights represented by this Warrant are exercisable by the Holder, in whole
or in part, by the surrender of this Warrant and the Notice of Exercise annexed hereto duly executed at the principal executive office of the Company (or such other office or agency of the Company as it may designate by notice in writing to the
Holder at the address of the Holder appearing on the books of the Company), and upon payment of the Exercise Price of the Shares thereby purchased (by cash or by check or bank draft payable to the order of the Company); whereupon the Holder shall be
entitled to receive a certificate for the number of Shares so purchased. The Company agrees that if at the time of the surrender of this Warrant and purchase of the Shares, the Holder shall be entitled to exercise this Warrant, the Shares so
purchased shall be and be deemed to be issued to the Holder as the record owner of such Shares as of the close of business on the date on which this Warrant shall have been exercised as aforesaid. 

  
 - 4 -

 (c) In lieu of exercising this Warrant by payment of cash or check pursuant to subsection
(b) above, the Holder may elect to receive Vested Shares equal to the value of the Warrant (based upon the value of the Vested Shares or the portion thereof being exercised), at any time after the date hereof and before the close of business on
the Expiration Date, by surrender of this Warrant at the principal executive office of the Company, together with the Notice of Conversion annexed hereto, in which event the Company will issue to the Holder Vested Shares in accordance with the
following formula: 
  

							
		  	X     =	  	 Y(A-B)
      A
	  	

  

					
	Where,	  	X     =	  	the number of Vested Shares to be issued to the Holder;
			
		  	Y     =	  	the number of Vested Shares for which the Warrant is being exercised;
			
		  	 A     =
	  	the fair market value of one Share; and
			
		  	B     =	  	the Exercise Price.

 For purposes of this subsection the fair market value of a Share is defined as follows: 

(1) if the exercise is in connection with an IPO, and if the Company’s registration statement relating to such IPO has been declared
effective by the Securities and Exchange Commission, then the fair market value shall be the initial “Price to Public” specified in the final prospectus with respect to the offering; 

(2) if the exercise is in connection with a Change of Control, then the fair market value shall be the value received in such Change of
Control by the holders of the securities as to which purchase rights under this Warrant exist; 
 (3) if the exercise occurs
after, and not in connection with an IPO, and: 
 a) if traded on a securities exchange or the Nasdaq Stock Market, the value
shall be deemed to be the average of the closing prices of the securities on such exchange or market over the thirty (30) day period ending three (3) days prior to the date of the Notice of Conversion; or 

b) if actively traded over-the-counter, the value shall
be deemed to be the average of the closing bid prices over the thirty (30) day period ending three (3) days prior to the date of the Notice of Conversion; 
 (4) if there is no active public market, the value shall be the fair market value thereof, as determined in good faith by the Company’s Board of Directors. 

3. Nonassessable. The Company covenants that all Shares which may be issued upon the exercise of rights represented by this
Warrant will, upon exercise of the rights represented by this Warrant, be validly issued, fully paid and nonassessable and free from all taxes, liens and charges in 

  
 - 5 -

 respect of the issue thereof (other than taxes in respect of any transfer occurring contemporaneously with
such issue). Certificates for Shares purchased hereunder shall be delivered to the Holder within a reasonable time after the date on which this Warrant shall have been exercised as aforesaid. 

4. No Fractional Shares or Scrip. No fractional shares or scrip representing fractional shares shall be issued upon the exercise
of this Warrant. With respect to any fraction of a share called for upon the exercise of this Warrant, an amount equal to such fraction multiplied by the then current price at which each Share may be purchased hereunder shall be paid in cash to the
Holder. 
 5. Charges, Taxes and Expenses. Issuance of certificates for Shares upon the exercise of this Warrant shall be
made without charge to the Holder hereof for any issue or transfer tax or other incidental expense in respect of the issuance of such certificate, all of which taxes and expenses shall be paid by the Company, and such certificates shall be issued in
the name of the Holder. 
 6. No Rights as Stockholder. This Warrant does not entitle the Holder to any voting rights or
other rights as a stockholder of the Company prior to the exercise hereof. 
 7. Loss, Theft, Destruction or Mutilation of
Warrant. On receipt of evidence satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant and, in the case of loss, theft or destruction, on delivery of an indemnity agreement satisfactory in form and substance to
the Company or, in the case of mutilation, on surrender and cancellation of this Warrant, the Company at its expense shall execute and deliver, in lieu of this Warrant, a new warrant of like tenor and amount. 

8. Saturdays, Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right
required or granted herein shall be a Saturday, a Sunday or a legal holiday, then such action may be taken or such right may be exercised on the next succeeding day not a Saturday, Sunday or legal holiday. 

9. Adjustments. The Exercise Price and the number of Shares purchasable hereunder are subject to adjustment from time to time as
set forth in this Section 9. 
 (a) Reclassification, etc. If the Company, at any time while this Warrant, or any
portion hereof, remains outstanding and unexpired by reclassification of securities or otherwise, shall change any of the securities as to which purchase rights under this Warrant exist into the same or a different number of securities or any other
class or classes, this Warrant shall thereafter represent the right to acquire such number and kind of securities as would have been issuable as the result of such change with respect to the securities that were subject to the purchase rights under
this Warrant immediately prior to such reclassification or other change and the Exercise Price therefor shall be appropriately adjusted, all subject to further adjustment as provided in this Section 9. 

(b) Subdivision or Combination of Shares. In the event that the Company shall at any time subdivide the outstanding securities as
to which purchase rights under this Warrant exist, or shall issue a stock dividend on the securities as to which purchase rights under this Warrant exist, the number of securities as to which purchase rights under this Warrant exist immediately
prior to such subdivision or to the issuance of such stock dividend shall be proportionately increased, and the 

  
 - 6 -

 
Exercise Price shall be proportionately decreased, and in the event that the Company shall at any time combine the outstanding securities as to which purchase rights under this Warrant exist, the
number of securities as to which purchase rights under this Warrant exist immediately prior to such combination shall be proportionately decreased, and the Exercise Price shall be proportionately increased, effective at the close of business on the
date of such subdivision, stock dividend or combination, as the case may be. 
 (c) Cash Distributions. No adjustment on
account of cash dividends or interest on the securities as to which purchase rights under this Warrant exist will be made to the Exercise Price under this Warrant. 
 (d) Antidilution Rights. Antidilution rights applicable to the Preferred Stock issuable upon the exercise of this Warrant are set forth in the Company’s Amended and Restated Certificate of
Incorporation (as it may be further amended or restated from time to time, the “Charter”), and shall be applicable with respect to the Preferred Stock issuable upon exercise of this Warrant. The Company shall
promptly provide the Holder with any restatement, amendment, modification or waiver of the Charter. For avoidance of any doubt, there shall be no duplicate antidilution adjustment pursuant to this Section 9(d) and the Charter. 

(e) Notice of Adjustments. If: (i) the Company shall declare any dividend or distribution upon its stock, whether in stock,
cash, property or other securities; (ii) the Company shall offer for subscription prorata to the holders of any class of its Preferred Stock any additional shares of stock of any class or other rights; (iii) there shall be any Change of
Control; (iv) there shall be an IPO; (v) the Company shall sell, lease, license or otherwise transfer all or substantially all of its assets; or (vi) there shall be voluntary dissolution, liquidation or winding up of the Company;

dividend, distribution, subscription rights (specifying the date on which the holders of the Preferred Stock shall be entitled thereto) or for determining rights to vote in respect of such Change of Control, dissolution, liquidation or winding up;
(B) in the case of any such Change of Control, sale, lease, license or other transfer of all or substantially all of the Company’s assts, dissolution, liquidation or winding up, at least fifteen (15) days’ prior written notice of

purchase hereunder after giving effect to such adjustment, and shall be given in the manner set forth in Section 15(e). 

  
 - 7 -

 (f) Timely Notice. Failure to timely provide such notice required by
Section 9(e) above shall entitle Holder to retain the benefit of the applicable notice period notwithstanding anything to the contrary contained in any insufficient notice received by Holder. 

10. Restrictions on Transferability of Securities. 
 (a) Restrictions on Transferability. The Securities shall not be sold, assigned, transferred or pledged except upon the conditions specified in this Section 10. 

(b) Restrictive Legend. Each certificate representing the Securities and any other securities issued in respect of the Securities
upon any stock split, stock dividend, recapitalization, merger, consolidation or similar event, shall (unless otherwise permitted by the provisions of Section 10(c)) be stamped or otherwise imprinted with a legend in the following form (in
addition to any legend required under applicable state securities laws): 
 THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE
NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR QUALIFIED UNDER APPLICABLE STATE SECURITIES LAWS AND MAY NOT BE SOLD, TRANSFERRED, ASSIGNED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER SUCH ACT AND QUALIFIED UNDER
APPLICABLE STATE SECURITIES LAWS, OR UNLESS THE CORPORATION HAS RECEIVED AN OPINION OF COUNSEL OR OTHER EVIDENCE, REASONABLY SATISFACTORY TO THE CORPORATION AND ITS COUNSEL, THAT SUCH REGISTRATION OR QUALIFICATION IS NOT REQUIRED. 

THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A LOCK-UP PERIOD OF UP TO 180 DAYS
FOLLOWING THE EFFECTIVE DATE OF A REGISTRATION STATEMENT OF THE COMPANY FILED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AS SET FORTH IN THAT CERTAIN STOCK PURCHASE WARRANT BETWEEN THE CORPORATION AND THE ORIGINAL HOLDER OF THESE SECURITIES, A
COPY OF WHICH MAY BE OBTAINED AT THE CORPORATION’S PRINCIPAL OFFICE. SUCH LOCK-UP PERIOD IS BINDING ON TRANSFEREES OF THESE SECURITIES. 

Each holder of Securities and each subsequent transferee consents to the Company making a notation on its records and giving instructions
to any transfer agent of the Securities in order to implement the restrictions on transfer established in this Section 10. 

(c) Notice of Proposed Transfers. Each holder of a warrant or stock certificate, as the case may be, representing the Securities,
by acceptance thereof, agrees to comply in all respects with the provisions of this Section 10(c). Such holder agrees not to make any disposition of all or any portion of the Securities unless and until there is then in effect a registration
statement under the 

  
 - 8 -

 Securities Act covering such proposed disposition and such disposition is made in accordance with such
registration statement or such holder shall have notified the Company of the proposed disposition and shall have furnished the Company with a detailed statement of the circumstances surrounding the proposed disposition, and if reasonably requested
by the Company, such holder shall have furnished the Company with an opinion of counsel, reasonably satisfactory to the Company that such disposition will not require registration of such shares under the Securities Act. 

11. Investment Representations of the Holder. With respect to the acquisition of any of the Securities, the Holder hereby
represents and warrants to the Company as follows: 
 (a) Purchase Entirely for Own Account. This Warrant is made with the
Holder in reliance upon the Holder’s representation to the Company, which by the Holder’s execution of this Warrant the Holder hereby confirms, that the Securities will be acquired for investment for the Holder’s own account, not as a
nominee or agent, and not with a view to the resale or distribution of any part thereof, and that the Holder has no present intention of selling, granting any participation in, or otherwise distributing the same. By executing this Warrant, the
Holder further represents that the Holder does not have any contract, undertaking, agreement or arrangement with any person to sell, transfer or grant participations to such person or to any third person with respect to any of the Securities.

 (b) Reliance upon Holders’ Representations. The Holder understands that the Securities have not been, and will not
be, registered under the Securities Act by reason of a specific exemption from the registration provisions of the Securities Act, and that the Company’s reliance on such exemption is predicated on the Holder’s representations set forth
herein. 
 (c) Investment Experience; Economic Risk. The Holder understands that the Company has a limited financial and
operating history and that an investment in the Company involves substantial risks. The Holder has made such inquiry concerning the Company and its business and personnel as it has deemed appropriate. The Holder has such knowledge and experience in
financial and business matters that the Holder is capable of evaluating the merits and risks of the investment in the Securities. The Holder can bear the economic risk of the Holder’s investment and is able, without impairing the Holder’s
financial condition, to hold the Securities for an indefinite period of time and to suffer a complete loss of the Holder’s investment. 
 (d) Accredited Investor Status. The Holder is an “accredited investor” within the meaning of Regulation D, Rule 501(a), promulgated under the Securities Act. The Holder also represents
that it has not been organized for the purpose of acquiring the Securities. 
 (e) Restricted Securities. The Holder
understands that the Securities are characterized as “restricted securities” under the federal securities laws inasmuch as they are being acquired from the Company in a transaction not involving a public offering and that under such
federal securities laws and applicable regulations such Securities may be resold without registration under the Securities Act only in certain limited circumstances. In this connection, Holder represents that it is aware of the provisions of Rule
144 promulgated under the Securities Act which permit limited resale of securities purchased in a private placement subject to the satisfaction of certain conditions, including, among other things, the existence of a public market for the securities
and the availability of certain current public information about the Company.

 12. Market Standoff. The Holder hereby agrees that, if requested by the managing
underwriter, it will not, without the prior written consent of the Company, during the period commencing on the date of the final prospectus relating to the Company’s IPO or any secondary public offering, as applicable, and ending on the date
specified by the Company and the managing underwriter (such period not to exceed one hundred eighty (180) calendar days in the case of an initial public offering and ninety (90) calendar days in the case of any secondary public offering
(or such other period as may be requested by the Company or managing underwriter to accommodate regulatory restrictions on (a) the publication or other distribution of research reports and (b) analyst recommendations and opinions,
including, but not limited to, the restrictions contained in FINRA Rule 2711(f)(4) or NYSE Rule 472(f)(4), or any successor provisions or amendments thereto)) (i) lend, offer, pledge, sell, contract to sell, sell any option or contract to
purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, or otherwise transfer or dispose of, directly or indirectly, any securities of the Company, including (without limitation) shares of Common Stock or
any securities convertible into or exercisable or exchangeable for Common Stock (whether now owned or hereafter acquired) or (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic
consequences of ownership of any securities of the Company, including (without limitation) shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock (whether now owned or hereafter acquired), whether

	Overview – Mavenir Statement of Work	  	Starent Networks Corporation

  

 1 Introduction 
 This document provides an overview for the Statement of Work requested from Mavenir Systems in order to jointly develop and deploy additional convergence server capabilities on the Mavenir Platform to
support CDMA Femtocell, mobile VoIP to GSM Core (or otherwise defined as MSC as TAS) and generic VoIP solutions. 
 2 Overview

 There are a variety of CDMA Femtocell architectures being positioned in the marketplace. Two approaches have risen to the
forefront of Starent discussions with the CDMA customer base; the Tunneled IOS Approach, and the IMS/SIP Approach. 
 Starent
Networks view that these two solution types are needed for CDMA. The Tunneled IOS approach will opportunistically be used as near term customer demand warrants. Strategically, Starent Networks is committed to a standards-based IMS/SIP based approach
for the CDMA Femtocell marketplace. These new features and functions can also be used to address more generic VoIP solutions, including but not limited to IMS based Femto, VoIP to GSM MSC (MSC as TAS), and Greenfield VoIP. 

This document identifies the high level work items requested for Mavenir Systems to include in its development and product roadmaps. It is
important to note, that continued discussion and architectural refinement is required to meet future standards and deliver a competitive and differentiated solution. 
 Definitions: 
 MSC as TAS is defined as SIP end points connected through a
broadband access through a Session Boarder Controller (SBC) to a 2G GSM MSC. 
 SCC is defined for legacy user equipment (in this
case CDMA 1xRTT) as a function providing terminating access domain selection function (T-ADS) as defined in 3GPP Release 8. 
 2.1 Work Item Overview 
 Shown in Table 2.1 are
the high level work items with program dates for the Mavenir deliverables. Shown in Table 2.2 are the “Solutions” and “Milestones” as referenced in the Reseller OEM Agreement between Mavenir Systems and Starent Networks. Sections
3, 4 and 5 provide more explanation on the specific work items.

 [***] 
 3.3 ICS MSC 
 This functional block is still pre-standard. Mavenir/Starent need to come to a common ground of understanding for this element. Conceptually, SIP should originate from the FAP, terminate directly into the IMS Core, and anchored in the SCC AS.
This block only comes into play for legacy/non SIP based FAP’s and is the mobility handoff point between CS and IMS service networks. 
 This block is also envisioned to capture the function for inter-MSC handoffs when acting as part of a MSC Softswitch environment. These interfaces include the
appropriate MAP functionality as specified in X.S0004-000-E_v7.0; including MAP-E, MAP-D,
and MAP-C. 
 This element also requires that Mavenir test and interoperates with various
CS-MGWs (media gateways) and Media Servers (MS) to be jointly defined based upon market need. 

3.4 IM TAS Features 
 A multi-phased solution is understood to be delivered by Mavenir; full 3GPP2 Compliant IM TAS offering.

 3.4.1 MSC as TAS 
 This solution allows the existing MSC’s within a carrier’s network to be used as Telephony Application Servers for generic IMS VoIP Solutions in a UMTS or GSM context. 

MSC as TAS is defined as “Connecting VoIP End Points via mOne to 2G GSM MSCs via a broadband access”. 

Mavenir is responsible for all interface development, interoperability, and certification to deliver the features listed in Appendix A.

 The target MSC’s should be jointly created between Mavenir and Starent during the System Definition and Specification
work item. 
 3.4.2 IM TAS 
 This solution enables an IMS based delivery of features and functions to the consumer base. This TAS should work with both generic SIP-based VoIP Endpoints, and
with defined Femto Base Stations. 
 Mavenir is responsible for all functional development, interface development,
interoperability, and certification to roll out the features listed in Appendix A. 
 A phased feature set is acceptable and is
outlined in Appendix A. The list should be finalized during the System Definition and Specification work item (3.1). 
 3.5 SMS Gateway

 The solution shall seamlessly support SMS GW as currently being developed by Mavenir Systems. This capability provides
an interworking function between legacy SMS and SIP-based messaging towards the IMS network. 

3.6 Network Management 
 All the above elements shall be seamless integrated into Mavenir’s Element Management System with full EMS functionality as part of the joint solution.

 Mavenir, Inc. 
 End-User License Agreement 
 This End User License
Agreement (“Agreement”), effective this         day of         ,         (“Effective Date”), is by and
between Mavenir, Inc., a Delaware corporation having offices at 1651 N Glenville, Suite 201, Richardson, TX 75081 (“Mavenir”)
and                     , a            
             located at
                                        
(“Licensee”). The parties hereby agree as follows: 

 

 1. LICENSE. 
 1.1 Software License Grant. This license applies to the object code version of Mavenir’s software (“Software”) contained in the Mavenir product (“Product”) purchased,
either alone or as incorporated in another product, by Licensee from Mavenir or its authorized representative. Mavenir grants to Licensee a limited, non-exclusive,
non-transferable, internal-use only, non-sub-licensable right to use one copy of the
Software in accordance with its applicable documentation. 
 1.2 Copies. Licensee may not copy the Software for
archival purposes. Licensee agrees to take all reasonable steps to protect the Software from unauthorized copying or use. 

1.3 Ownership. All right, title and interest in and to the Software and to any modifications, upgrades or updates thereto, and
any and all copies thereof including without limitation, all copyright, patent, and other proprietary rights therein, will, at all times, exclusively be owned by Mavenir. 
 1.4 Restrictions. Except as expressly authorized in this Agreement, Licensee may not rent, lease, sublicense, distribute, transfer, copy, reproduce, display, perform, transmit, modify or timeshare
the Software or any portion thereof, use the Software or any portion thereof on a service bureau basis, or remove or modify any notice of Mavenir’s proprietary rights. Licensee may not allow any third party or unlicensed user of Product to
access or use the Software. Licensee may not reverse engineer, de-compile or otherwise attempt to derive the source code for the Software or modify in any way, or create derivative works from the Software, or
any portion thereof. Licensee acknowledges and agrees that all improvements and modifications to the Software or any part thereof (whether

 
developed by Mavenir, Licensee or any third party acting on behalf of Licensee at any time during the term of this Agreement) will be and remain the sole and exclusive property of Mavenir.

 1.5 Upgrades and Updates. Any future upgrades, or updates to the Software provided to Licensee by Mavenir or its
representatives will be included in the definition of “Software” and will be subject to the terms and conditions of this Agreement. 
 1.6 Warranty. Mavenir warrants that, for twelve (12) months from the date of final acceptance by the Licensee, the Mavenir Software shall function substantially in the manner described in the
accompanying Mavenir documentation and shall be free from defects in materials and workmanship. Mavenir will, following its receipt of notice of a breach of this warranty during such twelve-month period: (i) correct the breach or
(ii) provide Licensee with a plan reasonably acceptable to Licensee for correcting the breach. Notwithstanding the foregoing, Mavenir shall have no obligation to fix errors in the Software caused by accident, misuse, abuse, improper operation,
misapplication, or any other cause external to the Software. 
 1.7 Disclaimer of Warranty. OTHER THAN THE SPECIFIC
WARRANTY IN SECTION 1.6, MAVENIR MAKES NO WARRANTY OR REPRESENTATION TO LICENSEE, EXPRESS OR IMPLIED, WITH RESPECT TO THE SOFTWARE. MAVENIR EXPRESSLY DISCLAIMS ANY AND ALL IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND
NONINFRINGEMENT. MAVENIR MAKES NO WARRANTY THAT ANY SOFTWARE 

 

  

	
	Page 1 of 5

 
WILL PERFORM ERROR-FREE OR UNINTERRUPTED, OR THAT ALL ERRORS THEREIN CAN OR WILL BE CORRECTED. MAVENIR FURTHER DISCLAIMS ANY IMPLIED WARRANTIES ARISING FROM COURSE OF PERFORMANCE, COURSE OF
DEALING OR USAGE OF TRADE. 
 2. CONFIDENTIALITY. 
 2.1 Confidential Information. For the purposes of this Agreement, “Confidential Information” will include all information designated as confidential or which could reasonably be assumed
to be confidential, including without limitation any and all present or future product or service information, technical or financial information, business strategies, practices, procedures, customer names or related data, details of any contracts
entered into by the parties, advertising and promotional ideas or materials, other business or technical information, documents, drawings, models, inventions, or copyrightable works that may be disclosed by Mavenir to the Licensee, whether such
disclosure is in written, oral, electronic, website-based, or other form. At all times, this Agreement and the Software will be considered Mavenir’s Confidential Information. 

2.2 Non-disclosure. Licensee and its representatives will maintain the secret and
confidential nature of the Confidential Information it receives, will permit access only to employees with a need to know for purposes of this Agreement, and will prevent access to it by third parties. Further, Licensee will, at a minimum, use the
same degree of care that it uses with respect to its own confidential information to prevent its use or disclosure, but in no event will Licensee use less than reasonable care. Licensee may use Confidential Information it receives only for the
furtherance of the purposes of this Agreement. 
 2.3 Exclusions. This Agreement imposes no obligation upon Licensee
with respect to the following categories of

 
information: (a) information that at the time of disclosure to Licensee was in the public domain (other than as a result of any breach of this Agreement); (b) information that was known
by Licensee prior to receipt from Mavenir or its representative without an obligation to keep it confidential (as proven by Licensee’s written records); (c) information that, after disclosure to Licensee, becomes known to the general
public through no act or omission of Licensee; (d) information developed independently by Licensee without reference to Confidential Information; or (e) information that is disclosed to Licensee without an obligation of confidentiality by
a third party having the legal right to do so (as proven by its written records). Licensee may disclose Confidential Information as required by court order, but only to the extent required by such order; provided, however, that Licensee gives
Mavenir prompt notice of such required disclosure and Mavenir has had a reasonable opportunity to object to or limit such order. 
 3.
INDEMNIFICATION. 
 3.1 Mavenir. Mavenir will indemnify, defend, and hold harmless Licensee against any third
party claim that the Software infringes any United States patent, copyright, or trade secret of such third party, provided that Mavenir is given prompt written notice of such claim. Licensee will fully cooperate in the defense of such claim, if
requested by Mavenir. Mavenir will have sole authority to defend or settle the claim. If the Software becomes subject to any such infringement claim, or if Mavenir believes that such a claim is likely, Mavenir may, at its sole option and in addition
to its indemnification obligation, (i) obtain for Licensee the right to continue using the Software or (ii) replace or modify the effected Software so that the Software becomes non-infringing while
giving substantially equivalent functionality. Mavenir will have no liability for infringement claims if the alleged infringement is based on or arises from (i) a modification of the Software made by anyone other than Mavenir, (ii) the use
of the Software not in accordance with the documentation, (iii) use of the Software in a manner other than as authorized by this

 

  

	
	Page 2 of 5

 
Agreement, (iv) use of the Software after Licensee has been notified by Company of a claim of infringement, or (v) the use of other than the then most current release of the Software.
THE FOREGOING STATES MAVENIR’S ENTIRE LIABILITY AND LICENSEE’S EXCLUSIVE REMEDY FOR ANY CLAIM OF INFRINGEMENT. 

3.2 Licensee. Other than those claims indemnified by Mavenir under this Agreement, Licensee will indemnify, defend and hold
harmless Mavenir against any third party claim arising out of Licensee’s use of the Product or the Software. 
 4. LIMITATION OF
LIABILITY. OTHER THAN THE INDEMNIFICATION OBLIGATION FOR INFRINGEMENT, THE CUMULATIVE, AGGREGATE LIABILITY OF MAVENIR TO LICENSEE FOR ALL CLAIMS RELATED TO THE SOFTWARE, THE SERVICES AND THIS AGREEMENT, WHETHER ARISING OUT OF CONTRACT, TORT,
NEGLIGENCE, STRICT LIABILITY OR OTHERWISE, WILL NOT EXCEED, AS APPLICABLE, (I) THE LICENSE FEES PAID TO MAVENIR FOR THE SOFTWARE; OR (II) THE AMOUNT PAID TO MAVENIR FOR THE PRODUCT (IF THE LICENSE FEES ARE NOT SPECIFIED) FROM WHICH THE CLAIM
AROSE. IN NO EVENT WILL MAVENIR BE LIABLE FOR ANY SPECIAL, INCIDENTAL, CONSEQUENTIAL, INDIRECT OR PUNITIVE DAMAGES ARISING IN ANY WAY OUT OF THE USE OF THE SOFTWARE OR THE PRODUCT OR OUT OF THIS AGREEMENT, INCLUDING WITHOUT LIMITATION, DAMAGES FOR
LOST PROFIT, LOST REVENUE, LOSS OF USE, LOSS OF DATA, COSTS OF RECREATING LOST DATA, THE COST OF ANY SUBSTITUTE EQUIPMENT, PROGRAM, OR DATA, OR CLAIMS BY ANY THIRD PARTY, WHETHER ARISING OUT OF CONTRACT, TORT, NEGLIGENCE, STRICT LIABILITY OR
OTHERWISE. 
 5. TERM AND TERMINATION. 
 5.1 Term. The term of this Agreement will commence on the Effective Date and will continue until terminated pursuant to its terms.

 5.2 Termination of Agreement. Either party may terminate this Agreement for cause
if the other party has materially breached this Agreement and has not corrected such breach within thirty (30) days of receipt of specific written notice of same. 
 5.3 Effect. Upon termination of this Agreement, Licensee agrees to immediately discontinue all use of the Software and return or destroy all copies of same to Mavenir. Licensee will deliver a
letter signed by a duly authorized officer of Licensee certifying compliance with the requirements set forth in this Section 5.3. 
 5.4 Survival. Those provisions that are intended to survive termination or expiration of this Agreement will so survive, including without limitation, Sections 1.3, 2, 3, 4, 5.3, 5.4, 6 and 7.

 6. REMEDIES AND ENFORCEMENT. Licensee acknowledges and agrees that a breach by Licensee of its obligations under
Section 1.4 or Section 2. would cause irreparable harm to Mavenir and that monetary damages would not be adequate to compensate Mavenir. Accordingly, Licensee agrees that Mavenir shall be entitled to immediate equitable relief, including,
without limitation, a temporary or permanent injunction, to prevent any threatened, likely or ongoing violation by Licensee, without the necessity of posting bond or other security. Mavenir’s right to equitable relief shall be in addition to
other rights and remedies available to Mavenir, for monetary damages or otherwise. 
 7. GENERAL CONDITIONS. 

7.1 Governing Law. Any disputes under this Agreement will be resolved under Texas law without reference to conflict of laws
principles. For any disputes arising out of this Agreement, the parties hereby consent and submit to the exclusive jurisdiction of the federal and state courts sitting in Dallas County, Texas.

 7.2 Relationship. This Agreement does not create any joint venture, partnership or
other fiduciary relationship between the parties. 
 7.3 Entire Agreement. This Agreement, sets forth the entire
understanding and agreement between Licensee and Mavenir and supersedes all proposals or communications, oral or written, between the parties relating to the subject matter of the Agreement. No modification of the Agreement will be binding unless in
a written agreement signed by authorized representatives of both parties. 
 7.4 Waiver. No waiver of any right under
this Agreement will be deemed effective unless contained in writing signed by a duly authorized representative of the party waiving such right, and no waiver of any past or present right arising from any breach or failure to perform will be deemed
to be a waiver of any future right arising under this Agreement. 
 7.5 Severability. If any provision in this
Agreement is invalid or unenforceable, that provision will be construed, limited, modified or, if necessary, severed, to the extent necessary, to eliminate its invalidity or unenforceability, and the other provisions of this Agreement will remain in
full force and effect. 
 7.6 Assignment. Mavenir may assign this Agreement to an entity acquiring it, whether by
merger, consolidation, stock purchase or otherwise acquiring substantially all of its assets. Licensee may not assign any of its rights or delegate any of its obligations under this Agreement to any third party without the express written consent of
Mavenir. Any attempted assignment in violation of the foregoing will be void and of no effect. Subject to the above, this Agreement will be binding upon and inure to the benefit of the successors and assigns of the parties hereto.

 7.7 Purchase Orders. Nothing contained in any purchase order, purchase order
acknowledgement, or invoice will in any way modify or add any additional terms or conditions to this Agreement.

beyond the reasonable control of a party hereto, either party is unable to perform in whole or in part its obligations as set forth in this Agreement (other than payment obligations), then such party will be relieved of those obligations to the
extent it is so unable to perform and such inability to perform will not make such party liable to the other party. Neither party will be liable for any loss, injury, delay or damages suffered or incurred by the other party due to the above causes.

 7.9 Notices. Any notice required or permitted to be sent under this Agreement will be delivered by hand, by
overnight courier, by facsimile (with confirmed transmission), or by registered mail, return receipt requested, to the address of the parties first set forth in this Agreement or to such other address of the parties designated in writing in
accordance with this Section 7.9.

 AMENDMENT NO. 1 
 AMENDMENT NO. 1 (“Amendment”),
dated as of February 10, 2009, between Starent Networks, Corp. (“Starent”) and Mavenir Systems, Inc. (“Mavenir”), to the Reseller OEM Agreement, dated October 28, 2008 (the “Agreement”), and the Statement of
Work, dated October 17, 2008 (the “SOW”), between the parties. 
 As Starent and Mavenir wish to revise the
Agreement and the SOW to remove a delivery milestone required by Mavenir, the parties agree as follows: 
 1. SOW, Table
2.2. 
 The parties agree to remove Milestone 1 (“Tunneled IOS with AirWalk IP RAN”) from Table 2.2 of the SOW.

 2. Agreement 
 (a) Section 6.7. 
 The parties agree that the Section 6.7 of the
Agreement will be amended as follows: 
 (i) The third sentence is hereby amended and restated as follows: 

“As a result, the Parties have agreed to establish a total of two milestones in connection with the development of the
Solutions (which shall herein be referred to as Milestones 2 and 3), as more fully set forth in the SOW (each, a “Milestone” and collectively, the “Milestones”).” 

(ii) The sixth sentence is hereby amended and restated as follows:

 ADDENDUM NO. 1 

This Addendum No. 1 (this “Addendum”), effective as of December 28, 2009 (the “Effective Date”), is made by and
between Cisco Systems, Inc. (“Cisco”) (as successor-in-interest to Starent Networks, Corp., a Delaware corporation (“Starent”)), having its primary office at 175 West Tasman Drive, San Jose, California 95134 and
Mavenir Systems, Inc., a Delaware corporation, with offices at 1700 International Place, Suite 200, Richardson, TX 75081 (“Mavenir”), in connection with that certain OEM Agreement between Starent and Mavenir dated October 28, 2008
(the “OEM Agreement”), and amends and restates in its entirety, as of the date signed by the last party, that original Addendum No. 1 executed by and between the parties hereto to be effective as of the Effective Date. Starent and Mavenir
shall each be referred to herein individually as a “Party” or collectively as the “Parties.” 

WHEREAS, Mavenir has agreed to provide, deploy and support certain social networking technologies to T-Mobile USA, Inc.
(“TMO”) to be integrated into TMO’s network, as more fully set forth in that certain Second Amendment to Master Agreement Between T-Mobile USA, Inc. and Starent Networks, Corp., dated as of December 23, 2009, which was previously
delivered by Starent to Mavenir on or about the Effective Date (the “Solution”); and  
 WHEREAS, the
Solution consists of Mavenir products and services and does not include Starent products or services; and 
 WHEREAS, the
Parties wish to establish the terms and conditions regarding, among other things, the provision of the Solution to TMO. 

NOW, THEREFORE, in consideration of the premises set forth above, the Parties agree as follows: 

 

	 	1.	Mavenir shall be fully and solely liable for supplying all products and services in connection with, and for the full and complete performance of, the Solution. Mavenir
shall be liable for the full amount of any and all liability, penalties, liquidated damages, costs, fees and the like (collectively, “Claims”) arising in connection with the Solution whether asserted against Starent or Mavenir. Mavenir
shall hold Starent harmless, and fully indemnify Starent, with respect to any Claims asserted by TMO or any third party arising in connection with the Solution in accordance with the OEM Agreement. 

 

	 	2.	Within thirty (30) days of receipt of any payment made by TMO to Starent in connection with the Solution, Starent shall pay to Mavenir [***] of all amounts actually
received by Starent. 

  

	 	3.	This Addendum is subject to the OEM Agreement. In the event any discrepancy exists between the OEM Agreement and this Addendum, the terms of this Addendum shall
prevail. 

  

	 	4.	This Addendum and the OEM Agreement (a) are complete, (b) constitute the entire understanding between the parties with respect to the subject matter hereof, and (c)
supersede all prior agreements, whether oral or written. No waiver, modification, or addition to this Addendum or the OEM Agreement shall be valid unless in writing and signed by the parties hereto. Except as expressly provided herein, the terms of
the OEM Agreement are hereby ratified and confirmed and remain in full force and effect. 

  

	 	5.	This Addendum shall be effective as of the Effective Date and amends and restates in its entirety that Addendum No. 1 executed by and between Mavenir and Starent on or
about the Effective Date. 

 IN WITNESS WHEREOF, as of the Effective Date, the Parties have caused this
Addendum to be executed by their duly authorized representatives.

TO THE 

RESELLER OEM AGREEMENT 
 Amendment No. 2, dated as of March 23, 2011 (the “Effective Date”), between Mavenir Systems, Inc. (“Mavenir”) and Cisco Systems, Inc. (“Cisco”) (which assigned the
Agreement (as defined below) on September 3, 2010 by Starent Networks LLC (f/k/a/ Starent Networks, Corp.)) (“Starent”), to the Reseller OEM Agreement, dated as of October 28, 2008 as amended (the “Agreement”). 

The parties agree to modify the Agreement as follows: 
  

	 	1.	Definitions 

 Insert the
following new Definitions: 
 “Cisco” means Cisco Systems, Inc. and its Affiliates. 

“CM” shall mean a Cisco authorized contract manufacturer. 

“Open Source License” means a software license under which source code is made available under terms that allow any licensee to

 At the beginning of 3rd sentence of Section 2.1(b), insert the following: “Except as set forth in Section 2.6 below,”... 
  

	 	3.	Mavenir Trademark and Copyright License. 

 Section 2.6 is deleted in its entirety and replaced with the following: “Starent may re-brand any Mavenir Product (including but not limited to: the
Mavenir Product, Mavenir Software graphical user interface and Mavenir Documentation) provided by Mavenir under this Agreement as a Starent brand or a Cisco brand. In addition Cisco may, with Mavenir’s prior written consent (which consent shall
not be unreasonably withheld or delayed), re-brand the Mavenir Product with a Starent and/or Cisco brand and any third party brand or with a third party brand. In the event that Starent or Cisco rebrands any
Mavenir Product pursuant to this Section 2.6, Cisco shall be pay to Mavenir all fees, costs and expenses, if any, mutually agreed upon by Mavenir and Cisco in writing and in accordance with the payment terms of Section 5 of the
Agreement.” 
  

	 	4.	Fees, Payments and Payment Terms. 

 In Section 5, titled “Fees, Payments and Payment Terms”. Section 5.3 titled “Support Fees” is deleted in its entirety and replaced with the following: “Cisco shall pay

31, January 31, April 30, July 31). 

  
 1 

 Section 5.4, titled “Payment Terms” is amended and restated as follows:

 5.4 Payment Terms. Mavenir shall invoice all fees and amounts due under any order upon shipment. Payment of such invoices
shall be due net sixty (60) days from Cisco’s receipt of invoice. Payment of an invoice without asserting a dispute is not a waiver of any claim or right. Payment shall not constitute Cisco’s Acceptance (as defined below) of the
Deliverables. Where Cisco or any Authorized Purchaser disputes a portion of an invoice, neither Cisco nor any Authorized Purchaser will withhold payment of undisputed amounts. All payments hereunder shall be made by wire transfer to such bank and
account as Mavenir may from time to time designate in writing. All payments shall be made in U.S. Dollars. Whenever any payment hereunder shall be stated to be due on a day which is not a day that banks are open for business in Boston, Massachusetts
(a “Business Day”), such payment shall be made on the immediately succeeding Business Day. Payments hereunder shall be considered to be made as of the day on which they are received at Mavenir’s designated bank. Any amounts payable by
Cisco or any Authorized Purchaser hereunder which remain unpaid after the due date may be subject to a late charge equal to the lesser of 1.25% per month or the maximum rate allowed by law. 

Section 5.8, titled “Delivery” is amended and restated as follows: 

“5.8 Forecast and Delivery. 
 Forecast. During the term of this Agreement, Cisco shall provide Mavenir on a monthly basis a twelve (12) month non-binding rolling projection of orders by
Cisco of the Mavenir Products, including quantities and Mavenir part numbers (“Forecast”). Notwithstanding any other provision contained herein, the parties acknowledge and agree that the Forecast can in no way be construed as a commitment
on Cisco’s part to purchase any Mavenir Products, unless specifically designated by Cisco as “committed orders” on such Forecast (the “Committed Orders”). If Cisco designates a Committed Order in its Forecast, then such
Committed Order shall be subject to the terms and conditions of this Agreement (including but not limited to: payment, cancellation and rescheduling sections). Cisco agrees to issue Mavenir a purchase order(s) for the Committed Orders no later than
four (4) weeks prior to the requested delivery date. 
 Delivery. Cisco shall from time to time place written
purchase orders for Mavenir Products under this Agreement. Orders shall specify the quantity of Mavenir Products to be delivered, delivery destination, and a requested shipment date. 

  
 2 

 Mavenir shall ship all Mavenir Products in accordance with the lead-time or delivery date
that is set forth on a purchase order and accepted by Mavenir. The maximum lead time for Mavenir Products shall be four (4) weeks for Committed Orders and ten (10) weeks for up to fifty percent (50%) of
non-committed Forecast orders and twelve (12) weeks for orders in excess of fifty percent (50%) of the non-committed Forecast. If Mavenir is unable to ship the
Mavenir Products by the agreed upon shipment date, Mavenir shall notify Cisco in writing and if such delay results in Cisco paying damages to an End User or Distributor, then Mavenir shall reimburse Cisco for such damages to the extent specifically
caused by Mavenir’s delay, such damages not to exceed the delay damages set forth in Cisco’s agreement with its End User or Distributor. At Cisco’s option, such credit shall be paid in cash or applied against future purchases and
reflected in future invoices. Mavenir shall accept or reject each purchase order submitted by Cisco within five (5) business days of Mavenir’s receipt of such purchase order. If Mavenir does not reject an order within five
(5) business days of receipt, the order will be deemed accepted. If Mavenir is more than 30 days late in shipping any Deliverables specified in the applicable purchase order. Cisco may, without liability, terminate any undelivered portion of
the purchase order and any other undelivered purchase orders for the same or substantially similar Deliverables. Cisco’s acceptance of all or any part of the Deliverables does not waive any claim that Cisco may have for delay damages under this
Section.” 
 Insert the following new Section 5.12. titled “Authorized Purchasers”: 

5.12. Upon the Effective Date, Mavenir agrees to allow Cisco non-Affiliated CMs and Cisco
Affiliates acting in the capacity of CMs (the “Authorized Purchasers”) to order Mavenir Products on behalf of Cisco, which Mavenir Products will be incorporated into, bundled with, sold in conjunction with Cisco products or on a standalone
basis. The following Sections of this Agreement shall apply to any such purchases by Authorized Purchasers of Mavenir Products for inclusion in or with Cisco products (collectively the “Authorized Purchaser Required Sections”): Sections 2,
3.1, 4.1, 5.1, 6.1 through 6.6, 10 and 16. Mavenir will manage the applicable aspects of delivery and fulfillment of Mavenir Products directly to Authorized Purchasers. Notwithstanding anything to the contrary in this Agreement or any non-disclosure agreement executed by Mavenir and Cisco, Cisco may disclose the terms of this Agreement to its Authorized Purchasers without Mavenir’s consent solely for the Authorized Purchasers use in
purchasing Mavenir Products for Cisco, provided such Authorized Purchasers agree to comply with the terms of Section 9 hereof. With respect to Mavenir Products ordered by Authorized Purchasers, Mavenir shall invoice such Authorized Purchaser
directly and Cisco shall have no liability for any such Order. The parties agree that the Authorized Purchasers shall not be third party beneficiaries of this Agreement, and further that Cisco has the right to enforce terms under this Agreement
directly, notwithstanding the fact that Orders for the Mavenir Products may be issued by the Authorized Purchasers for Cisco. In no event shall Cisco’s or CM’s payment of any invoice constitute Cisco’s acceptance of any Deliverables.

  
 3 

 Insert the following new Section 5.13. titled “Cancellation/Rescheduling of Orders
and Committed Forecast” 
 Cisco may cancel, at no charge to Cisco, any Committed Order(s) in the Forecast or any purchase
order placed by Cisco up to six (6) weeks prior to the scheduled delivery date. 
 Cisco may reschedule, at no charge to
Cisco, any Committed Order(s) in the Forecast or any purchase order placed by Cisco up to two (2) weeks prior to the scheduled delivery date, provided that such rescheduling is within three (3) months from the original scheduled delivery
date. 
  

	 	5.	Acceptance. 

Section 6.1 is delete in its entirety and insert the following: “Unless otherwise agreed, acceptance of the initial shipment of
each Mavenir Product type (“Acceptance”) to an End User shall occur upon the earlier of (a) formal acceptance of the Mavenir Products by the End User or (b) one hundred twenty (120) days following delivery of the Mavenir
Products to Cisco (unless rejected in writing by Cisco within such period). For subsequent shipments of previously Accepted Mavenir Products by an End User, Acceptance shall occur upon the earlier of (a) formal acceptance of the Mavenir
Products by the End User or (b) sixty (60) days following delivery of the Mavenir Products to Cisco (unless rejected in writing by Cisco within such period). 
 In the event the End User rejects the Mavenir Products, and Cisco is required by the End User to refund any amounts paid by the End User for the Mavenir Products, Mavenir will refund any amounts paid by
Cisco for such Mavenir Products. 
  

	 	6.	Warranties. 

Section 10.2 (e), Following the end of the sentence, insert: “In addition, Mavenir warrants to Cisco as of the Effective Date
that the Mavenir Products do not contain any Open Source Technology other than as set forth on Appendix I, and to the extent that Mavenir desires to include any additional Open Source Technology after the Effective Date, then Mavenir will comply
with Cisco’s Open Source Guidelines attached hereto and incorporated herein as Appendix J.”

party to provide Open Source Code for all or a portion of the Open Source Technology (the “Request”), and the Open Source Code requested has not already been provided by Mavenir to Cisco under Section 17.2, then Cisco shall notify
Mavenir and refer the requestor to Mavenir. 
 17.4.1 If Mavenir is obligated to provide all or part of the requested Source Code

 5

 CISCO OPEN SOURCE GUIDELINES 

 Open Source Guidelines for Cisco Suppliers 
  

  
 

 
 Open Source Guidelines for Cisco Suppliers 

 

	1	Introduction 

 These
Open Source Guidelines for Cisco Suppliers (“Guidelines”) specify what information must be provided, and what procedures must be followed, before a supplier provides materials to Cisco that include open source technology. For
example, these Guidelines would apply to you in the following situations1: 
  

	 	•	 	 You are licensing proprietary technology to Cisco that includes open source components; 

 

	 	•	 	 You are designing technology for Cisco that will include open source components; 

 

	 	•	 	 You are selling to Cisco a hardware product that has open source technology (i) bundled with it; (ii) installed on it;
(iii) incorporated into firmware as part of the product; or (iv) distributed separately, but intended to be used with the product. 

  

	 	•	 	 You are providing Cisco with open source technology in conjunction with services for Cisco or its partners or customers; 

 

	 	•	 	 Any other situation where you provide open source components to Cisco for eventual distribution to Cisco customers, partners or other vendors.

 By “open source technology,” we mean any technology that is subject to an open source license. These are
generally licenses that make source code available for free modification and distribution. Examples of open source licenses include the Berkeley Software Distribution (BSD), the MIT license, the different versions of the Mozilla and Apache licenses,
and all of the licenses sponsored by the Free Software Foundation, including the GNU General Public License (GPL) and the GNU Lesser General Public License (LGPL). A legal definition of open source technology is provided in your contract with Cisco.

 Certain open source licenses apply their terms to modifications and additions that a licensee makes to the original code. In addition,
certain licenses—such as the GPL and the LGPL—apply their terms to code that links to, or interacts in certain ways with, the original code. For purposes of these Guidelines, all such code should be considered open source technology.

  

	2	Cisco, Open Source and You 

 Cisco views
the open source community as a valuable supply base whose works must be respected and used appropriately. While open source technology allows us to develop new products quickly and to leverage widely accepted platforms and standards, we recognize
that open source technology also comes with risks and obligations. 
  

 
 1 These are intended as examples and not a comprehensive list.

 Open Source Guidelines for Cisco Suppliers 
  

 Cisco intends to comply with its open source license obligations, to manage risks in a sensible manner,
and to be a positive contributor to the open source community. To this end, we have enacted policies and procedures that our engineers must follow when they build products or services containing open source technology. Our suppliers must comply as
well, because when they provide us with deliverables containing open source technology, they are placing obligations and risks directly upon Cisco. 
 Cisco needs to understand and manage these risks and obligations before any deliverables are used in a Cisco product or service. These Guidelines are designed to ensure that we have the information
needed to accomplish this. 
 Cisco will monitor each supplier’s compliance with these Guidelines. Failure to comply may cause a supplier
to be removed from Cisco’s Approved Vendor List, and the supplier may not be considered for future business with Cisco. 
  

	3	Open Source Requirements: 

All suppliers should provide the following to Cisco: 
  

	 	1.	Import Archive. The Import Archive helps Cisco to understand the open source technology in the deliverables and to prepare to meet the licensing obligations
associated with that technology. The Import Archive consists of three elements: 

  

	 	a.	A spreadsheet listing information about each open source component contained in the deliverables (e.g., name of component, version number, where obtained,
licensing information, etc.). 

  

	 	—	In order to ensure that you have the most recent version of the spreadsheet, please obtain the current template from the Cisco person with whom you are working (your
“Cisco contact”). 

  

	 	—	An Initial draft of the spreadsheet must be provided prior to contract signing. 

 

	 	b.	Licensing text files for each of the components listed in the spreadsheet. 

 

	 	—	See the spreadsheet template for instructions on how to prepare the licensing text files. 

 

	 	—	Licensing files must accompany the Initial spreadsheet prior to contract signing. 

 

	 	c.	The source code for each component listed in the spreadsheet. 

  

	 	—	The source code should be pristine source as it was acquired from the original provider, and should be the version of that component as utilized in the deliverables.

  

					
	 Cisco Systems, Inc.

15APR2010
	 	Page 2 of 5	 	CISCO CONFIDENTAL

 Open Source Guidelines for Cisco Suppliers 
  

	 	—	The source code must be provided with the deliverables. 

  

	 	2.	Publication Archive. The Publication Archive enables Cisco to meet its obligation to publish source code as required by certain open source licenses (such
as the General Public License ver. 2, the Lesser General Public License, the Mozilla Public License, etc.) The Publication Archive must contain all code required for each open source component in the deliverables. This requirement is driven by the
particular license governing each component. 

  

	 	—	It is your obligation to review each license and ensure that all required source code is provided to Cisco. 

 

	 	—	The Publication Archive must be delivered no later than the date specified in the contract. 

Top-level README file. Along with the Publication Archive, you must provide a file named
“README” at the root of the Publication Archive which contains instructions (such as an ordered list of Unix shell commands) for building the source code into installable object code. This README file should also contain a table of
requirements identifying the name, version number, and origin (such as a URL) for each software package required for compilation, installation, and execution of the code in the Publication Archive, if those packages are not themselves present in the
Publication Archive. For example, a Publication Archive containing only a “Hello, World!” program source file (“hello.c”) and a simple Make file for generating an executable program, might provide a requirements table similar to
the following: 
  

					
	 Package Name
	  	 Version
	  	 Origin

	GNU Compiler Collection (gcc)	  	4.4.1	  	http://gcc.gnu.org/gcc-4.4/
	GNU binutils	  	2.19.1	  	http://www.gnu.org/software/binutils/
	GNU C Library	  	2.10.1	  	http://www.gnu.org/software/libc/
	GNU Make	  	3.81	  	http://www.gnu.org/software/make/

 If the software package required for development of the code in the Publication Archive originated from a
distributor (such as Red Hat Enterprise Linux, Debian GNU/Linux, or Ubuntu), then it is acceptable to prepare the table using the output of the corresponding package management commands, such as “rpm
-qa” for RPM-based systems or “dpkg-l” for DEB-based systems. Please prune
such lists of all software packages that are not required. 
 If a required package is proprietary and available only on
a commercial basis, then the name of the licensor or distributor, along with a URL, contact address (email or traditional, or both), and/or phone number. 
 NOTE: If you have modified any of the required technology such that the modifications are required to correctly compile, install, or execute any of the code in the Publication Archive, then (if you
have a license to distribute the

	 	Page 3 of 5	 	CISCO CONFIDENTAL

 Open Source Guidelines for Cisco Suppliers 
  

 modified versions) you must provide the modified versions in the Publication Archive, in
a subdirectory of the root called “REQUIREMENTS”, which should in turn contain one archive file or unpacked directory of modified source code for each modified requirement. If you do not have license to distribute the requirements in
modified source form, then you should note their modified status by placing the word “MODIFIED” after the version number in the “README” file. 
 The README file should be in plain-text format. 
  

	 	3.	Build Log and Verification Archive: 

 The Build Log and Verification Archive allows Cisco to verify that the Publication Archive (see above) provided is accurate and complete. 

The Build Log and Verification Archive must be delivered no later than the date specified in the contract terms. 

An acceptable Build Log and Verification Archive must satisfy the following list of requirements; we provide Unix shell commands as
examples to guide you in developing your own procedures. 
  

	 	a.	In order to document the completeness of the Publication Archive, you must provide a Build Log for that code. This log should: 

 

	 	i.	Demonstrate or provide as part of the log a standard, secure cryptographic hash of the archive: 

 

	 	—	md5sum myarchive.tar.gz 

  

	 	—	or shasum -a 256 myarchive.tar.gz

  

	 	ii.	Demonstrate the unpacking of the archive: 

  

	 	—	tar xzvf myarchive.tar.gz 

  

	 	iii.	Demonstrate the build process: 

  

	 	—	cd myarchive 

  

	 	—	./configure 

  

	 	—	make 

  

	 	iv.	Demonstrate the installation of the archive results (not necessarily at device level, but at least at filesystem level): 

 

	 	—	make install 

  

	 	v.	Demonstrate as part of the log the standard, secure cryptographic hash of the resultant artifact(s), as for example: 

 

	 	—	find $INSTALL_DlR -print | xargs md5sum 

 

	 	—	or find $INSTALL_DIR -print | xargs shasum -a 256

  

	 	vi.	If you are providing Cisco with a product image, demonstrate building the product image with the results of the publication archive build.

 Open Source Guidelines for Cisco Suppliers 
  

	 	vii.	If you are providing Cisco with a product image, demonstrate or provide as part of the log the standard, secure cryptographic hash of the resultant product image.

  

	 	viii.	Include the complete output of the above demonstrations. 

  

	 	b.	In addition, to allow Cisco to verify the accuracy of the build log, you must do one of the following: 

 

	 	i.	Provide a Verification Archive. The Verification Archive should contain sufficient additional materials to allow Cisco to build the resulting product image using the
source code provided by the Publication Archive. The simplest and recommended way to achieve this is to provide a virtual machine, executable by VMWare Player and containing all necessary tools, the Publication Archive, binary objects for
vendors’ proprietary technology, and instructions for a simple entry point to build the image from the publication archive sources and the provided binary objects. (For example, cd $START_DlR;make;make install). The instructions should be
provided in a file named README at the root directory of the filesystem of the VM. 

 or 

 

	 	ii.	If you do not wish to provide such a VM, you should provide all necessary tools, publication archive, binary objects, supporting libraries, instructions, and so forth
such that Cisco can replicate the build of the product image using the Publication Archive source code. 

  

	4	Updates 

 All information and source code
and packed files provided to Cisco pursuant to these Guidelines must be updated at the time the deliverables are updated. In addition, you must notify Cisco promptly if you add additional open source technology to any deliverable. Prompt
notification should be provided in accordance with the contract.
