1. WEC REGIONAL MEETINGISTANBUL OCTOBER 17, 2008 ITGI PROJECT Dr. Vasileios Tsompanopoulos General Director Corporate Development & Planning DEPA S.A.

2. The Gas Corridor through Turkey, Greece and Italy (ITGI) The ITGI corridor will allow the establishment of an additional gas transport route from diversified gas production sources in Caspian and Middle East regions through Turkey and Greece to Italy.

3. Overview of the ITGI The ITGI Corridor will, in its completed form, comprise: • The Interconnector Turkey – Greece (ITG), already in operation, as well as future upgrades associated to the Turkish Grid and • The Interconnector Greece Italy (IGI) that will consist of: ─ the on-shore pipeline to be built between the North East part of Greece and Ionian Coast ─ the off-shore pipeline, namely IGI Poseidon, to be built between the Greek Ionian Coast and Italy

4. The Interconnector Turkey-Greece and theTurkish section • The ITG pipeline connecting Turkey with Greece has an actual capacity of 3.5 bcm/yr that with certain investments in compression stations can be increased up to a max capacity of 11.5 bcm/yr. • The Turkish gas network is already extended from east to west and its transportation capacity will require some future upgrades in order to secure, in addition with growing domestic demand, long term transit capacity. • Under the Trilateral Intergovernmental Agreement, the maximum ITG Project Capacity (i.e. 11,5 bcm/yr) will be reserved to the Greek Market and to transit for the IGI Poseidon.

5. The Greek on-shore section The onshore section of the IGI Project will run from Komotini to Ionian coast and will be realized by DESFA (Greek TSO unbundled from DEPA)

6. The off-shore section : The Poseidon Pipeline The Poseidon Pipeline will be realized by Poseidon Co. a 50/50% Joint Venture between Edison and Depa already incorporated since June 2008. The Poseidon Pipeline will run from Ionian coast (Thesprotia area) to Otranto (Italy) and will also include the onshore facilities at the Greek and Italian shore approach.

7. IGIPoseidon SA Edison and Depa have incorporated, under the Law of Greece, IGI Poseidon S.A. IGI Poseidon will develop, finance, realize, own and operate the Poseidon Pipeline Project according to applicable regulations and legislations in Italy and Greece. Edison 50% IGI Poseidon DEPA 50% A TPA Exemption for the Poseidon Pipeline has been approved for an Exempted Capacity of 8 bcm per year for 25 years (Edison 6.4 bcm/y ; Depa 1.6 bcm/y) Additional Capacity : up to 1bcm/y to third Parties Via Open Season

8. IGI Poseidon S.A. Open Season Following the approval by AEEG, RAE and Greek Ministry of Development of the “Poseidon Pipeline Open Season Procedure Regulation”, Edison and Depa, have launched on June 20th , the Open Season Procedure for the allocation to third Parties of approx. 1bcm/y of additional transportation capacity. The Open Season Procedure foresees the following time schedule: More details available on www.igi-poseidon.com

9. Institutional Framework of the ITGI Corridor (1/2) The Intergovernmental Agreement between Italy and Greece executed on November 4th 2005 and the IntergovernmentalAgreement among Turkey, Greece and Italy executed on July 26th 2007 secure Government’s support to the development of the Project. In Particular, the Trilateral Intergovernmental Agreement defines: • The Government commitment to ensure that relevant TSOs will develop, operate and maintain the sections of the ITGI Project within their territories; • The Governments support to the timely execution of the transit agreements between TSOs and Shippers, and to the fulfillment of the deriving obligations of the respective TSOs; • That Botas, DESFA and Poseidon Co. will act as Transmission System Operators (TSOs) providing transit services to, among the others, Edison and Depa as shippers through the exempted capacity of the Poseidon pipeline (8bcm/y); • That the maximum technical capacity of the Interconnector Turkey – Greece (i.e. 11.6 bcm/y) shall be dedicated and shall serve the transit for the Poseidon pipeline and for the Greek gas market. • That transportation tariffs through the Turkish, Greek and Poseidon networks shall be based on cost-reflective principles using reasonable returns for incurred investments; • The Governments commitment to ensure uninterrupted flow of transit volumes through their territories;

10. Institutional Framework of the ITGI Corridor (2/2) The execution of the MOU between Greece and Azerbaijan signed on August 2, 2007 in Baku and the execution of the Protocol of Agreement between Italy and Azerbaijan signed in Baku on December 12, 2007 constitute a major step in the completion of the institutional framework supporting the ITGI Project. In accordance with these Agreements, Coordination Committees have been established to ensure the necessary support also to the negotiations between Depa and Edison with Socar for gas supply contracts for quantities and duration consistent with the size of the ITGI Corridor and relevant upstream projects in Azerbaijan.

11. IGI Project: Commercial Activities Gas Supply Contracts: Following the execution of the Memorandum of Cooperation between Greece and Azerbaijan, and of the Protocol of Agreement between Italy and Azerbaijan, Edison and Depa are in relative discussions with gas producers from Azerbaijan (Shah Deniz Consortium). Gas Transit Agreements with Turkey: Following the trilateral Intergovernmental Agreement among Turkey, Greece and Italy signed on July 26th 2007, Edison and Depa are in the process of completing an agreement with Botas for the purpose of initiating appropriate discussions for gas transit agreements, safeguarding Project feasibility.

12. IGI Project: Commercial Activities Gas Transit Agreements in Greece: • Edison, Depa and DESFA have agreed to start negotiations for the execution of Advanced Reservation Capacity Agreements (ARCAs), to be defined according to the principles approved by RAE. Such Agreements are required to: • Safeguard DESFA in the development of the onshore section of the IGI Project • Reserve Capacity in Greece to Edison and Depa for further development of the Poseidon Pipeline • Definitive Transit agreements will be executed between Edison/Depa and Desfa upon the finalization of the Greek secondaryregulation for transit currently under completion by the Authorities

13. Poseidon Development Plan • Completed Basic Engineering and Reconnaissance Marine Survey. Offshore Route finalized and Optimized. Hydraulic Analysis Updated. Capex Estimation performed. Contracting and Construction Strategy elaborated. • Obtained Ministerial Decrees in Italy and Greece for inclusion of IGI Project within national development plans. • Activated authorisation procedures to build and operate the IGI project in Italy and Greece. • Obtained TPA Exemption. • Secured consistent and coordinated capacity development in Greece and in Turkey, via the institutional support to the ITGI Project derived by the Intergovernmental Agreement among Italy, Greece and Turkey (July 2007). • Detail Engineering and Marine Survey contracts under tendering procedure. • Final Authorisations in Italy and in Greece planned by 1H 2009. • Open Season Procedure under progress. • Finalisation of Transportation Agreements for exempted capacity within mid 2009.
