ARRIS Standard Software License Terms and Warranty Table

Unless your company has executed a separate agreement which contains terms and conditions for software licensing of

ARRIS products, you must agree to the below terms and conditions to receive download and support. ARRIS products, both

Hardware and Software, contain proprietary information and trade secrets that are confidential information of ARRIS.

ARRIS reserves the right to audit the use of Customer’s Hardware and Software.

Definitions and Interpretation

Within this document the following terms are defined as follows:

“ARRIS” means ARRIS Solutions, Inc., a wholly owned subsidiary of ARRIS Enterprises, Inc. and/or its designated affiliates.

“Customer” means the person or entity however constituted to whom the Products or Services are provided.

“Hardware” means equipment designed and manufactured by ARRIS, or other manufacturer's equipment offered for sale

by ARRIS to Customer.

“Software” means ARRIS-licensed software, including updates, and any other enhancements, modifications, and bug fixes

thereto, in object code form only, and any full or partial copies thereof. Software is licensed by ARRIS separately or as part

of a Product sale.

Provided that the Customer has paid all applicable license fees to ARRIS, and assuming that the Customer has not

negotiated a separate specific agreement or been granted a third-party license with the Software, then ARRIS grants to

Customer a limited, royalty-free, nonexclusive and nontransferable, non-sublicensable license limited solely to the use of

the Software’s application with the Hardware, if applicable, sold in conjunction with the Software for its intended

purposes, which purposes preclude Customer’s provision of any product or service to a third party that would alleviate any

third party from the obligation or need to obtain a separate license to the Software. All rights, title to and ownership of all

applicable intellectual property rights in the Software, including but not limited to patents, copyrights and trade secrets

remain with ARRIS and its licensors. Customer shall not attempt to acquire any other rights or transfer any ownership

rights in the Software in contravention to ARRIS’ rights. ARRIS’ rights extend to any accompanying printed materials and

online or electronic documentation, and any authorized copies of the above materials. The Software as used herein

includes unpublished software, trade secret and confidential or proprietary information of ARRIS or its licensors and is

developed at private expense. Customer may use third-party software products or modules supplied by ARRIS solely with

the Products, unless the licensing terms of the third-party software specify otherwise.

Customer shall not modify, create derivative works, reverse engineer, decompile, disassemble or in any manner attempt to

derive the source code from the Software, in whole or in part, except and only to the extent that such activity is expressly

permitted by applicable law. Customer is entitled to make a single copy of the Software solely for backup or archival

purposes and all title, trademark, copyright, restricted rights or any other proprietary notices shall be reproduced in such

copy. Unless otherwise agreed to in writing, Customer shall not otherwise use, copy, modify, lend, share, lease, rent,

assign, sub-license, provide service bureau, hosting or subscriptions services, or distribute or transfer the Software or any

copies thereof, in whole or in part, except as expressly provided in these terms and conditions. Customer further agrees

not to publish or disclose any benchmark tests run on the Software. Customer shall not remove, obscure or alter any

notice of copyright, patent, trade secret, trademark or other proprietary right or disclaimer appearing in or on any

Software Products or accompanying materials. All rights not expressly granted hereunder are reserved by ARRIS.

The Software may contain embedded third-party software (“Embedded Third-party Software). The licensors of such

Embedded Third-party Software shall be third party beneficiaries entitled to enforce all rights and obtain all benefits which

relate to such licensors under these terms and conditions. The licensors of such Embedded Third-party Software shall not

be liable or responsible for any of ARRIS’ covenants or obligations under these terms and conditions, and Customer’s rights

or remedies with respect to any Embedded Third-party Software under these terms and conditions shall be against ARRIS.

Customer shall not directly access or use any embedded third-party software independently of the Software unless

Customer obtains appropriate licenses. Under certain circumstances, ARRIS will advise that Customer needs to obtain a

license for other third-party software (“Third-party Software”) for use in conjunction with the Software. Customer agrees

that the terms and conditions agreed to between Customer and such Third-party Software vendor, including but not

limited to warranties, indemnification and support, shall be solely between Customer and the Third-party Software vendor,

and ARRIS shall not have any responsibility or liability for such Third-party Software. ARRIS Products may contain Open

Source software. If Open Source is used, upon written request from an ARRIS customer, ARRIS will make available the

appropriate Open Source software as per the applicable GPL.
