Introduction The way people consume content is changing due to new habits and technological innovation. More and more people do not organize their leisure time around fixed programming schedules. Further, thanks to new transmission technologies and devices, distribution of the same digital content to multiple end user devices via different transmission means is now widely available. In consequence, while Sky has been serving its subscribers predominantly via satellite and DSL redistribution of programming to Set Top Boxes, Sky has recently launched linear and non-linear programming services via new means of delivery (e.g., IP streaming and downloading) intended to be received by new consumer receiving devices (e.g., portable End User Devices (including tablets and smart phones), personal computers and game consoles). The purpose of these extensions is to strengthen the Sky core proposition of providing high quality television services to its new and existing consumer base and to accommodate emerging consumer behaviours. Sky customers shall enjoy their favorite contents on non- traditional devices with more interactivity and robust security Page 3 of 20 Sky Italia Confidential February 2012 This document is the intellectual property of Sky Italia and contains confidential information.

As of its launch, the service currently branded “Sky Go” is available through : “Sky Go“ website : A website based access to linear and non-linear services, targeting receiving devices such as personal computers, game consoles, connected TVs, but also portable End User Devices such as tablets and smart phones; and “Sky Go“ application : An application based access to linear and non-linear services, targeting receiving devices such as iPad and similar tablets as well as smart phones and other portable End User Devices. 1.2 Sky “anytime” : Non-linear Services Sky is offering those subscribers seeking to access content in a more time-flexible manner the possibility to view Sky controlled programming anytime on a non-linear basis. At launch, the service currently branded “Sky On Demand” will be made available both via the platform of portable End User Devices as described above through either : “Sky On Demand” website : A website based access to non-linear services, targeting receiving devices such as personal computers, game consoles, connected TVs, but also portable End User Devices such as tablets and smart phones; and “Sky On Demand” application : An application based access to non-linear services targeting receiving devices such as iPad and similar tablets as well as smart phones and other portable End User Devices; and to Set Top Boxes through : “Sky On Demand” STB EPG application : An EPG based access to non-linear services, targeting PVR Set Top Boxes for the purpose of DTH delivery of content on a push basis and IP delivery on a pull basis. 2. Delivery Infrastructure 2.1 Means of Transmission of Video and Audio Signals Historically, Sky provided television services to Set Top Boxes via DTH and DSL lines. Going forward, Sky will also be transmitting programming (in linear and non-linear modes of delivery) to users using multiple types of receiving devices via other delivery means through Closed Access Internet.
