2. AT&T Business Fast Track – Enterprise: Description, Provisioning Arrangements, and Billing

2.1 Enhanced Network Experience. AT&T Business Fast Track – Enterprise uses quality of service (“QoS”) network technology to enable qualified enterprise and government customers to receive a differentiated (i.e., enhanced versus “best effort”) 4G LTE network experience for eligible data traffic (as described in this Attachment) originated on and traversing over the AT&T-owned domestic 4G LTE network (i.e., excluding microcells, AT&T Wi-Fi service, and roaming partners’ networks). An enhanced, or higher, QoS is particularly valuable during times of network congestion. AT&T Business Fast Track – Enterprise does not provide priority access to the AT&T-owned domestic 4G LTE network.

2.2 Provisioning Arrangements. AT&T Business Fast Track—Enterprise is a flexible solution and can be provisioned for Customers in three ways: (a) as a monthly recurring feature charge that is added to Customer’s qualified Wireless Data Service Plan(s) on a per CRU line basis and for use with specific customer-designated applications known as Approved Business Applications (defined below); (b) as a monthly recurring feature charge that is added to Customer’s qualified Wireless Data Service Plan(s) on a per CRU line basis and invoked by the individual CRU on an “on-demand” basis through the use of the AT&T Business Fast Track—Enterprise Application (the “App”); and (c) as part of a bundled offering with certain advanced wireless service solutions, including AT&T Enhanced-Push-To-Talk (“Specialized Services”).

2.3 Billing and Usage Limitations. When provisioned for use with Approved Business Applications or for use with the App AT&T Business Fast Track – Enterprise is billed on a monthly billing cycle basis for $10 per month, beginning in the month on which AT&T Business Fast Track—Enterprise is placed on the CRU line. Usage of the feature with an Approved Business Application or the App is limited to 10 GB per month; after 10 GB have been used, all traffic is handled on a “best efforts” basis. Any unused AT&T Business Fast Track usage below the 10GB limit will be forfeited at the end of the month, cannot be carried over and are not subject to refund. No proration of the monthly charge is offered for termination prior to the expiration of a billing cycle.

Pricing and additional information pertaining to the use of AT&T Business Fast Track--Enterprise when bundled with a Specialized Service, such as AT&T Enhanced-Push-To-Talk, are set forth in the Sales Information for each Specialized Service found at www.att.com/abs-addtl-terms, as may be amended from time.

3 AT&T Business Fast Track-Enterprise: Use with the App.

Customers can give their individual CRU lines the ability to invoke AT&T Business Fast Track—Enterprise on an on-demand through the use of the App. The App allows CRUs provisioned with AT&T Business Fast Track—Enterprise the ability to apply a higher QoS to all of the data traffic sent to and from their 4G LTE-capable device for the duration of a session initiated and terminated by the CRU.

3.2 The App. In order to use the App in connection with AT&T Business Fast Track—Enterprise, individual CRUs must download the App onto their 4G LTE-capable wireless devices from generally available app stores, such as Apple iTunes®, Google Play® and certain AT&T-hosted apps marketplaces. The device will accept wireless application protocol (WAP) Push notification to illuminate the indicator. The App requires Customer and individual CRUs to accept the terms of an End User License Agreement (“EULA”) prior to use. The terms of the EULA are located at www.att.com/adtmmobileeula.Once downloaded and activated by the CRU, the App will prompt the CRU to complete a tutorial prior to the initiation of the first session of use for the feature.

3.3 Initiation and Termination of a Session. CRUs can activate a session for use of AT&T Business Fast Track—Enterprise by launching the App and choosing the criteria used to terminate the session. CRUs can choose to limit their session by time or by the amount of data used in conjunction with AT&T Business Fast Track—Enterprise. Both options are available through a drop-down menu on the app. Once the CRU has reached the designated time or data limitations for use of the feature, the CRU’s AT&T Business Fast Track—Enterprise session will end, and their data traffic will resume being treated on a “best efforts” basis in accordance with the terms of their wireless data services plan, unless the CRU chooses to extend the session. In addition to time and data usage duration parameters, CRUs can use the App to configure a pre-set geographic zone in which AT&T Business Fast Track—Enterprise will automatically be invoked for the duration of time that the CRU is within the preset geographic zone. The AT&T Business Fast Track—Enterprise session will automatically end when the CRU leaves the preset geographic area, unless extended by the CRU.

3.4 Allotment Usage with the App. Once a CRU line has reached the 10 GB monthly limitation on use of AT&T Business Fast Track—Enterprise, the CRU will not be able to extend an existing session or begin a new session for use of the feature for the remainder of the billing period.
