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 islocated outside the Americas) (suchapplicable entitybeing referred to herein as “Juniper”), and (ii) the person or organization thatoriginally purchased fromJuniper oran authorizedJuniper 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 fromJuniper 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 ofthe applicablefees andthe limitationsand 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 limitsto Customer’s use of the Software. Such limitsmay restrict use to a maximumnumber 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 markson or in any copy ofthe Softwareor 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 secondhandmarket; (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.

M7i Router Description

The M7i Multiservice Edge Router is a complete routing system that provides ATM, channelized, Ethernet, IP services, and SONET/SDH interfaces for large networks and network applications, such as those supported by Internet service providers (ISPs).

The router accommodates up to four Physical Interface Cards (PICs). In addition to the PICs, the Fixed Interface Card (FIC) provides two Fast Ethernet ports or one Gigabit Ethernet port, depending on your configuration. The built-in tunnel interface on the Compact Forwarding Engine Board (CFEB) and Enhanced Compact Forwarding Engine Board (CFEB-E) provides tunneling services. The optional Adaptive Services Module (ASM) on the CFEB and CFEB-E, and the optional MultiServices Module (MSM) on the CFEB-E allow one or more services to be configured on this interface.

The router architecture cleanly separates control operations from packet forwarding operations,which helps to eliminateprocessing and trafficbottlenecks.Control operations in the router are performed by the Routing Engine, which runs Junos OS to handle routing protocols,traffic engineering, policy, policing, monitoring, and configuration management.

Application-specific integrated circuits (ASICs), a definitive part of the router design, enable the router to forward data at the high speeds demanded by current network media. Forwarding operations in the router are performed by the Packet Forwarding Engine, which consists of hardware, including ASICs, designed by Juniper Networks. The Packet Forwarding Engine can forward up to 16 million packets per second (Mpps) for all packet sizes. The aggregate throughput is 4 gigabits per second (Gbps), full duplex, for the FPC with 4 PIC slots. The fixed interface card (FIC) has a maximum throughput of 1 Gbps full duplex. Inserting a combination of PICs with an aggregate higher than the maximum throughput of the FPC is supported, but constitutes oversubscription of the FPC.
