END USER LICENSE AGREEMENT

READ THIS END USER LICENSE AGREEMENT (“AGREEMENT”) BEFORE DOWNLOADING, INSTALLING, OR USING THE SOFTWARE.

BY DOWNLOADING, INSTALLING, OR USING THE SOFTWARE OR OTHERWISE EXPRESSING YOUR AGREEMENT TO THE TERMS

CONTAINED HEREIN, YOU (AS CUSTOMER OR IF YOU ARE NOT THE CUSTOMER, AS A REPRESENTATIVE/AGENT AUTHORIZED TO

BIND THE CUSTOMER) CONSENT TO BE BOUND BY THIS AGREEMENT. IF YOU DO NOT OR CANNOT AGREE TO THE TERMS CONTAINED

HEREIN, THEN (A) DO NOT DOWNLOAD, INSTALL, OR USE THE SOFTWARE, AND (B) YOU MAY CONTACT JUNIPER NETWORKS

REGARDING LICENSE TERMS.

1. The Parties. The parties to this Agreement are (i) Juniper Networks, Inc. (if the Customer’s principal office is located in the Americas) or

Juniper Networks (Cayman) Limited (if the Customer’s principal office is located outside the Americas) (such applicable entity being referred

to herein as “Juniper”), and (ii) the person or organization that originally purchased from Juniper or an authorized Juniper reseller the applicable

license(s) for use of the Software (“Customer”) (collectively, the “Parties”).

2. The Software. In this Agreement, “Software” means the program modules and features of the Juniper or Juniper-supplied software, for

which Customer has paid the applicable license or support fees to Juniper or an authorized Juniper reseller, or which was embedded by

Juniper in equipment which Customer purchased from Juniper or an authorized Juniper reseller. “Software” also includes updates, upgrades

and new releases of such software. “Embedded Software” means Software which Juniper has embedded in or loaded onto the Juniper

equipment and any updates, upgrades, additions or replacements which are subsequently embedded in or loaded onto the equipment.

3. License Grant. Subject to payment of the applicable fees and the limitations and restrictions set forth herein, Juniper grants to Customer

a non-exclusive and non-transferable license, without right to sublicense, to use the Software, in executable form only, subject to the

following use restrictions:

a. Customer shall use Embedded Software solely as embedded in, and for execution on, Juniper equipment originally purchased by

Customer from Juniper or an authorized Juniper reseller.

b. Customer shall use the Software on a single hardware chassis having a single processing unit, or as many chassis or processing units

for which Customer has paid the applicable license fees; provided, however, with respect to the Steel-Belted Radius or Odyssey Access

Client software only, Customer shall use such Software on a single computer containing a single physical random access memory space

and containing any number of processors. Use of the Steel-Belted Radius or IMS AAA software on multiple computers or virtual machines

(e.g., Solaris zones) requires multiple licenses, regardless of whether such computers or virtualizations are physically contained on a single

chassis.

c. Product purchase documents, paper or electronic user documentation, and/or the particular licenses purchased by Customer may

specify limits to Customer’s use of the Software. Such limits may restrict use to a maximum number of seats, registered endpoints, concurrent

users, sessions, calls, connections, subscribers, clusters, nodes, realms, devices, links, ports or transactions, or require the purchase of

separate licenses to use particular features, functionalities, services, applications, operations, or capabilities, or provide throughput,

performance, configuration, bandwidth, interface, processing, temporal, or geographical limits. In addition, such limits may restrict the use

of the Software to managing certain kinds of networks or require the Software to be used only in conjunction with other specific Software.

Customer’s use of the Software shall be subject to all such limitations and purchase of all applicable licenses.

d. For any trial copy of the Software, Customer’s right to use the Software expires 30 days after download, installation or use of the

Software. Customer may operate the Software after the 30-day trial period only if Customer pays for a license to do so. Customer may not

extend or create an additional trial period by re-installing the Software after the 30-day trial period.

e. The Global Enterprise Edition of the Steel-Belted Radius software may be used by Customer only to manage access to Customer’s

enterprise network. Specifically, service provider customers are expressly prohibited from using the Global Enterprise Edition of the

Steel-Belted Radius software to support any commercial network access services.

The foregoing license is not transferable or assignable by Customer. No license is granted herein to any user who did not originally purchase

the applicable license(s) for the Software from Juniper or an authorized Juniper reseller.

4. Use Prohibitions. Notwithstanding the foregoing, the license provided herein does not permit the Customer to, and Customer agrees

not to and shall not: (a) modify, unbundle, reverse engineer, or create derivative works based on the Software; (b) make unauthorized

copies of the Software (except as necessary for backup purposes); (c) rent, sell, transfer, or grant any rights in and to any copy of the

Software, in any form, to any third party; (d) remove any proprietary notices, labels, or marks on or in any copy of the Software or any product

in which the Software is embedded; (e) distribute any copy of the Software to any third party, including as may be embedded in Juniper

equipment sold in the secondhand market; (f) use any ‘locked’ or key-restricted feature, function, service, application, operation, or capability

without first purchasing the applicable license(s) and obtaining a valid key from Juniper, even if such feature, function, service, application,

operation, or capability is enabled without a key; (g) distribute any key for the Software provided by Juniper to any third party; (h) use the

Software in any manner that extends or is broader than the uses purchased by Customer from Juniper or an authorized Juniper reseller; (i)

use Embedded Software on non-Juniper equipment; (j) use Embedded Software (or make it available for use) on Juniper equipment that

the Customer did not originally purchase from Juniper or an authorized Juniper reseller; (k) disclose the results of testing or benchmarking

of the Software to any third party without the prior written consent of Juniper; or (l) use the Software in any manner other than as expressly

provided herein.

5. Audit. Customer shall maintain accurate records as necessary to verify compliance with this Agreement. Upon request by Juniper,

Customer shall furnish such records to Juniper and certify its compliance with this Agreement.

6. Confidentiality. The Parties agree that aspects of the Software and associated documentation are the confidential property of Juniper.

As such, Customer shall exercise all reasonable commercial efforts to maintain the Software and associated documentation in confidence,

which at a minimum includes restricting access to the Software to Customer employees and contractors having a need to use the Software

for Customer’s internal business purposes.

7. Ownership. Juniper and Juniper’s licensors, respectively, retain ownership of all right, title, and interest (including copyright) in and to

the Software, associated documentation, and all copies of the Software. Nothing in this Agreement constitutes a transfer or conveyance

of any right, title, or interest in the Software or associated documentation, or a sale of the Software, associated documentation, or copies

of the Software.

8. Warranty, Limitation of Liability, Disclaimer of Warranty. The warranty applicable to the Software shall be as set forth in the warranty

statement that accompanies the Software (the “Warranty Statement”). Nothing in this Agreement shall give rise to any obligation to support

the Software. Support services may be purchased separately. Any such support shall be governed by a separate, written support services

agreement. TO THE MAXIMUM EXTENT PERMITTED BY LAW, JUNIPER SHALL NOT BE LIABLE FOR ANY LOST PROFITS, LOSS OF DATA,

OR COSTSORPROCUREMENTOF SUBSTITUTE GOODS OR SERVICES,OR FOR ANY SPECIAL, INDIRECT, OR CONSEQUENTIALDAMAGES

ARISING OUT OF THIS AGREEMENT, THE SOFTWARE, OR ANY JUNIPER OR JUNIPER-SUPPLIED SOFTWARE. IN NO EVENT SHALL JUNIPER

BE LIABLE FOR DAMAGES ARISING FROM UNAUTHORIZED OR IMPROPER USE OF ANY JUNIPER OR JUNIPER-SUPPLIED SOFTWARE.

EXCEPT AS EXPRESSLY PROVIDED IN THE WARRANTY STATEMENT TO THE EXTENT PERMITTED BY LAW, JUNIPER DISCLAIMS ANY

AND ALL WARRANTIES IN AND TO THE SOFTWARE (WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE), INCLUDING ANY

IMPLIED WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR NONINFRINGEMENT. IN NO EVENT DOES

JUNIPER WARRANT THAT THE SOFTWARE, OR ANY EQUIPMENT OR NETWORK RUNNING THE SOFTWARE, WILL OPERATE WITHOUT

ERROR OR INTERRUPTION, OR WILL BE FREE OF VULNERABILITY TO INTRUSION OR ATTACK. In no event shall Juniper’s or its suppliers’

or licensors’ liability to Customer, whether in contract, tort (including negligence), breach of warranty, or otherwise, exceed the price paid

by Customer for the Software that gave rise to the claim, or if the Software is embedded in another Juniper product, the price paid by

Customer for such other product. Customer acknowledges and agrees that Juniper has set its prices and entered into this Agreement in

reliance upon the disclaimers of warranty and the limitations of liability set forth herein, that the same reflect an allocation of risk between

the Parties (including the risk that a contract remedy may fail of its essential purpose and cause consequential loss), and that the same

form an essential basis of the bargain between the Parties.

9. Termination. Any breach of this Agreement or failure by Customer to pay any applicable fees due shall result in automatic termination

of the license granted herein. Upon such termination, Customer shall destroy or return to Juniper all copies of the Software and related

documentation in Customer’s possession or control.

10. Taxes. All license fees payable under this agreement are exclusive of tax. Customer shall be responsible for paying Taxes arising from

the purchase of the license, or importation or use of the Software. If applicable, valid exemption documentation for each taxing jurisdiction

shall be provided to Juniper prior to invoicing, and Customer shall promptly notify Juniper if their exemption is revoked or modified. All

payments made by Customer shall be net of any applicable withholding tax. Customer will provide reasonable assistance to Juniper in

connection with such withholding taxes by promptly: providing Juniper with valid tax receipts and other required documentation showing

Customer’s payment of any withholding taxes; completing appropriate applications that would reduce the amount of withholding tax to

be paid; and notifying and assisting Juniper in any audit or tax proceeding related to transactions hereunder. Customer shall comply with

all applicable tax laws and regulations, and Customer will promptly pay or reimburse Juniper for all costs and damages related to any

liability incurred by Juniper as a result of Customer’s non-compliance or delay with its responsibilities herein. Customer’s obligations under

this Section shall survive termination or expiration of this Agreement.

11. Export. Customer agrees to comply with all applicable export laws and restrictions and regulations of any United States and any

applicable foreign agency or authority, and not to export or re-export the Software or any direct product thereof in violation of any such

restrictions, laws or regulations, or without all necessary approvals. Customer shall be liable for any such violations. The version of the

Software supplied to Customer may contain encryption or other capabilities restricting Customer’s ability to export the Software without

an export license.

12. Commercial Computer Software. The Software is “commercial computer software” and is provided with restricted rights. Use,

duplication, or disclosure by the United States government is subject to restrictions set forth in this Agreement and as provided in DFARS

227.7201 through 227.7202-4, FAR 12.212, FAR 27.405(b)(2), FAR 52.227-19, or FAR 52.227-14(ALT III) as applicable.

13. Interface Information. To the extent required by applicable law, and at Customer's written request, Juniper shall provide Customer

with the interface information needed to achieve interoperability between the Software and another independently created program, on

payment of applicable fee, if any. Customer shall observe strict obligations of confidentiality with respect to such information and shall use

such information in compliance with any applicable terms and conditions upon which Juniper makes such information available.

14. Third Party Software. Any licensor of Juniper whose software is embedded in the Software and any supplier of Juniper whose products

or technology are embedded in (or services are accessed by) the Software shall be a third party beneficiary with respect to this Agreement,

and such licensor or vendor shall have the right to enforce this Agreement in its own name as if it were Juniper. In addition, certain third party

software may be provided with the Software and is subject to the accompanying license(s), if any, of its respective owner(s). To the extent

portions of the Software are distributed under and subject to open source licenses obligating Juniper to make the source code for such

portions publicly available (such as the GNU General Public License (“GPL”) or the GNU Library General Public License (“LGPL”)), Juniper

principles. The provisions of the U.N. Convention for the International Sale of Goods shall not apply to this Agreement. For any disputes

arising under this Agreement, the Parties hereby consent to the personal and exclusive jurisdiction of, and venue in, the state and federal

courts within Santa Clara County, California. This Agreement constitutes the entire and sole agreement between Juniper and the Customer

with respect to the Software, and supersedes all prior and contemporaneous agreements relating to the Software, whether oral or written

(including any inconsistent terms contained in a purchase order), except that the terms of a separate written agreement executed by an

authorized Juniper representative and Customer shall govern to the extent such terms are inconsistent or conflict with terms contained

herein. No modification to this Agreement nor any waiver of any rights hereunder shall be effective unless expressly assented to in writing

by the party to be charged. If any portion of this Agreement is held invalid, the Parties agree that such invalidity shall not affect the validity

of the remainder of this Agreement. This Agreement and associated documentation has been written in the English language, and the

Parties agree that the English version will govern. (For Canada: Les parties aux présentés confirment leur volonté que cette convention de
