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.

Confidential and Proprietary Page 13

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.

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.

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

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.

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.

(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;

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.

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.

(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.

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.

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.

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.

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.

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.

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.

AMENDMENT NO. 2

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

2. License and Restrictions.

At the beginning of 3^rd 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 the Maintenance and Support fees set forth in Appendix B-1 within sixty (60) days following the end of each of Cisco’s fiscal quarters (October 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.”

7. Open Source.

Insert a new Section 17 as follows and renumber the existing “Section 17” to “Section 18”:

“Section 17 Open Source Technology”

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.

Cisco Systems, Inc. 15APR2010 Page 1 of 5 CISCO CONFIDENTAL

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

Cisco Systems, Inc. 15APR2010 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.

Cisco Systems, Inc. 15APR2010 Page 4 of 5 CISCO CONFIDENTAL

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.

5 Questions?

Your Cisco contact is available to point you in the right direction. Please get in touch with him or her if you need further guidance.
