2 Delibera ARG/gas 184/09 Continuous contacts The regulatory review process Dec, 2008 First contact Jan-Mar, 2009 Technical meetings March 31st, 2009 First public Consultation Document May 15th, 2009 First SRG Comments on Consultation July 23rd, 2009 Second public Consultation Document September 15th, 2009 Second SRG Comments on Consultation Sep-Dec, 2009 Proactive discussion December 2nd, 2009 Criteria for setting tariffs (Delibera ARG/gas 184/09) December 18th, 2009 Tariff proposal by transmission company December 23rd, 2009 Tariff approval by the Authority (Delibera ARG/gas 198/09) to protect the value 2

3 Fair outcome Clear and Stable 4-year regulatory period (from 2010 to 2013) Transparent methodology to calculate allowed revenues RAB based on re-valuated historical cost methodology Extra-return allowance on Attractive incentives Extra-efficiency retention on operating costs Financial efficiency retained in the period Long term visibility Up to 15 years premium on Profit sharing retention gradually transferred to shippers in 8 years Low risk profile No inflation exposure (yearly adjustment of RAB and revenues) Very low gas demand exposure (increased capacity revenue) No exposure to fuel gas cost (pass through) 3

4 Main figures 6.4% in real terms pre-tax Return On RAB 1% premium for 5 years for safety capex 2% premium for 7-10 years for capacity development capex 3% premium for years for entry-capacity development capex Base rate and premium recognised on spending Depreciation 50 years pipeline (vs. 40 years in previous periods) 20 years pressure reduction system (vs. 40 years in previous periods) 5 years for ICT system (vs. 10 years in previous periods) Operating costs Actual cost of year 2008 increased by 50% of extra efficiency (RPI X) applied only on commodity unit revenue X-factor determined to transfer extra efficiency in 8 years Tariff Commodity reference volume: 75.7 bcm Entry/Exit tariff system confirmed 4
