3. 3 Cloud Computing Projected Growth

4. Cloud - Key Business Drivers/Enablers  Easier, faster scalability enabling organizations to grow without time-intensive and resource- intensive IT build-outs.  Greater flexibility in adding, subtracting, or changing services in response to seasonal dynamics or business expansions or contractions.  A more agile IT infrastructure that enables organizations to rapidly transform ideas into marketable products and services.  Access to services across different geographies.  Cost effective due to the transformation of capital-intensive investments to pay-as-you-go pricing. 4

10. Value Proposition for Customers Better Economics People Centric Collaboration Flexible Platform Flexible Deployment Business Enabler Rich User Experience The Avaya Windstream Difference for Enterprises  Flexible deployment with Private or Hybrid option on the proven, industry leading Avaya Aura UC platform  Utility subscription model helps business scale with usage and demand (Opex model)  Hybrid cloud deployments help migration to cloud at customer’s own pace and deploying new applications at a low cost and low risk while leveraging existing investments  Consistent and seamless user experience across on-premises and cloud, across mobile devices supporting enterprise BYOD  Industry leading full PBX functionality and comprehensive set of UC and CC applications with rich APIs enabling custom application development and integration  Enterprise system management and control through Control manager interface exposed to end-customer  Session based all SIP architecture helps simplify, migrate, centralize and consolidate disparate, legacy infrastructure  Inherent security and application privacy with virtualized applications

11. HOSTED PRIVATE BENEFITS Ideal for Greenfield opportunities requiring a high degree of customization and for Hybrid Hosted integrated with CPE. Typically targeting the Enterprise market. May not require ACCCM or may require fewer administrator licenses (End customers can manage their environments via traditional Avaya tools. ACCCM may provide some benefit to Service Providers for single point of entry management). Human error impacts fewer end customers (Administrative errors that cause application outages or security breaches). Greater end customer security. System Manager, Presence Services, 1xCES, ACE all sync to only one directory source. This becomes more of a non-issue with Hosted Private. Other adjuncts that don’t support Tenant Partitioning, like Modular Messaging, don’t become an issue. All translations are propagated out to Survivable Branch and Core. Not an issue with Hosted Private. May create security concerns with Hosted Public since a customer with Survivable Branch would have not only their image but the image for all other CM tenants in their physical control. Can be used to ease transition of installed Avaya Red and Blue base to more cost effectively enable BYOD and Video applications from the Service Provider Cloud. Highly customizable for Hosted Private opportunities.

12. Private Per Client Instance 12

13. Ideal for Greenfield opportunities not requiring a lot of customization. Typically, targeting the mid-market and below. Simplified RTU administration and billing from Avaya to Service Provider (very large systems versus many smaller systems). Smaller Data Center footprint for non-virtualized applications. Can leverage Tenant Partitioning features of AACM and CMS. End customer usage of Avaya Concurrent Licensing is less impactful due to greater scale and customer diversity (For example – Shift overlap of CC Agents, softphones, video, etc. would potentially create a lower high water mark of RTU (and hence billing from Avaya) versus Hosted Private). Can be used to target installed Avaya Red and Blue base to more cost effectively enable BYOD and Video applications from the Service Provider Cloud. Would likely be more of a generic offer which would have a lower price point than Hosted Private. HOSTED PUBLIC BENEFITS
