1 GAS TRANSMISSION TARIFFS YEAR st JANUARY st DECEMBER 2011 Gas transmission tariffs have been calculated according to the provisions of the Delibera ARG/gas 184/09 published on 23 rd December 2009 by the Authority for Electricity and Gas. Gas transmission tariff for firm service on annual basis The gas transmission tariff T for firm service on annual basis is defined by the following formula: where: T = (Ke * CPe) + (Ku * CPu) + (Kr * CRr) + V * (CV+CV P ); - Ke is the capacity booked by the user at entry point e of the national transmission network, expressed in Sm 3 /day; - CPe is the capacity charge for the national transmission service related to the capacity booked at entry point e of the national transmission network, expressed in Euro/y/ Sm 3 /d; - Ku is the capacity booked by the user at exit point u of the national transmission network, expressed in Sm 3 /day; - CPu is the capacity charge for the national transmission service related to the capacity booked at exit point u of the national transmission network, expressed in Euro/y/ Sm 3 /d; - Kr is the capacity booked by the user at redelivery point r of the regional transmission network, expressed in Sm 3 /day; - CRr is the national capacity charge for the regional transmission service related to the capacity booked at redelivery point r of the regional transmission network, expressed in Euro/y/ Sm 3 /d; - V is the gas quantity injected into the network, expressed in Sm 3 ; - CV is the commodity charge, expressed in Euro/ Sm 3 ; - CV P is the additional commodity charge, expressed in Euro/ Sm 3. The capacity charges CPe, CPu, CRr are applied to booked capacity independently from its actual utilization, while the commodity charges CV and CV P are applied to the actual gas quantities injected into the network in each of the entry point of the national transmission network, excluding entry points interconnected with storage systems. Gas transmission tariff for interruptible transmission service According to the comma 11.1 of the Annex A of Delibera ARG/gas 184/09 ( RTTG ), the interruptible transmission service is made available at entry points interconnected with foreign pipelines and it s subjected to the following charge reductions, defined on the base of cost economies associated to this type of service: - a 10% reduction of the CPe charge applies to interruptible capacity of first rank; - a 20% reduction of the CPe charge applies to interruptible capacity of second rank. The capacity charges CPu and CRr and the commodity charges CV and CV P are the same applied to firm capacity.

2 The table below shows the characteristics of the interruptible service on the basis of which the charges are applied and paid for the whole contractual period. Characteristics of the interruptible transmission service

3 The charge for the interruptible transmission service at the entry point of Vittorio Veneto, to be paid for the whole contractual period, is subject to a 10% reduction and the service is referred to an interruption in absence of a net exit physical flow at the redelivery point of Vittorio Veneto (REMI ). Gas transmission tariff for firm capacity on infra-annual basis According to the comma 10.1 of RTTG, a firm transmission service is made available at entry points interconnected with foreign pipelines and with regasification terminals on semi-annual, quarterly and monthly basis. The related charges are determined by applying the coefficients shown in the following table to the CPe capacity charges proportioned on monthly basis.

6 TARIFF FOR METERING SERVICE YEAR st JANUARY 31 st DECEMBER 2011 The tariff for metering service has been calculated according to the provisions of the Delibera ARG/gas 184/09 published on 23 rd December 2009 by the Authority for Electricity and Gas. Tariffs for Metering Service for year 2011 The tariff for metering service TM for gas transmission service on annual basis is defined by the following formula: where: TM = Kr * CM T ; - Kr is the capacity booked by the user at redelivery point r of the regional transmission network, expressed in Sm 3 /day; - CM T is the transitory charge for metering service, according to the comma 2.1 of the Delibera ARG/gas 184/09, for the year 2011, related to the capacity booked at redelivery point r of the regional transmission network, expressed in Euro/y/ Sm 3 /d; The transitory charge CM T for year 2011, as approved with Delibera ARG/gas 218/10 of the Authority for Electricity and Gas, is listed in the following table: GAS METERING TARIFF 1 st JANUARY st DECEMBER 2011 TabLe 1.6 Transitory charge for metering service CM T EURO/y/Sm 3 /d CM T 0,059114

7 NUMERICAL MODEL A shipper has to supply a customer in Milan, with a consumption equal to 2,7 million cubic meter (38,1 MJ/Sm 3 ). The quantities are delivered at the entry point of Tarvisio and re-delivered at the Redelivery point of Milan. For this scope the shipper shall ask the following booking capacities: Entry point of Tarvisio = Sm 3 /d Entry point of Hub storage = Sm 3 /d Exit point = Sm 3 /d Exit point of Hub storage = Sm 3 /d Redelivery point of Milan = Sm 3 /d The charge for transportation capacity is calculated as shown in the following example: Capacity charges for the national transmission network (see tab1.1) see Municipalities Withdrawal Areas Database Entry Point TARVISIO HUB Storage.
