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 Juniper Networks, Inc. and its subsidiaries (collectively "Juniper"), and 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, and updates and

releases of such software, for which Customer has paid the applicable license or support fees to Juniper or an authorized Juniper reseller.

! iii

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 the Software solely as embedded in, and for execution on, Juniper equipment originally purchased by Customer from Juniper or an

authorized Juniper reseller, unless the applicable Juniper documentation expressly permits installation on non-Juniper equipment.

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.

c. Other Juniper documentation for the Software (such as product purchase documents, documents accompanying the product, the Software user

manual(s), Juniper's website for the Software, or messages displayed by the Software) may specify limits to Customer's use of the Software. Such limits may

restrict use to a maximum number of seats, concurrent users, sessions, subscribers, nodes, or transactions, or require the purchase of separate licenses to

use particular features, functionalities, or capabilities, or provide temporal or geographical limits. Customer's use of the Software shall be subject to all such

limitations and purchase of all applicable licenses.

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, 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; (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, or capability without first purchasing the

applicable license(s) and obtaining a valid key from Juniper, even if such feature, function, 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 the Software on non-Juniper equipment where the Juniper documentation does not expressly permit

installation on non-Juniper equipment; (j) use the Software (or make it available for use) on Juniper equipment that the Customer did not originally purchase

from Juniper or an authorized Juniper reseller; or (k) 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.

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. If the Software is distributed on physical media (such as CD), Juniper warrants for 90 days

from delivery that the media on which the Software is delivered will be free of defects in material and workmanship under normal use. This limited

warranty extends only to the Customer. Except as may be expressly provided in separate documentation from Juniper, no other warranties apply to the

Software, and the Software is otherwise provided AS IS. Customer assumes all risks arising from use of the Software. Customer's sole remedy and Juniper's

entire liability under this limited warranty is that Juniper, at its option, will repair or replace the media containing the Software, or provide a refund,

provided that Customer makes a proper warranty claim to Juniper, in writing, within the warranty period. Nothing in this Agreem

ent shall give rise to any

obligation to support the Software. Any such support shall be governed by a separate, written agreement. To the maximum extent permitted by law, Juniper

shall not be liable for any liability for lost profits, loss of data or costs or procurement of substitute goods or services, or for any special, indirect, or

consequential damages 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 HEREIN OR IN SEPARATE DOCUMENTATION PROVIDED FROM JUNIPER AND 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.

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 for the Software are exclusive of taxes, withholdings, duties, or levies (collectively "Taxes"). Customer shall be responsible for

paying Taxes arising from the purchase of the license, or importation or use of the Software.

11. Ex por t. 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 you may contain encryption or

other capabilities restricting your 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. Miscellaneous. This Agreement shall be governed by the laws of the State of California without reference to its conflicts of laws principles. 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.
