3 1. SUBJECT This Appendix presents the applicable terms, rates, and pricing structure for using the TIGF transmission network in accordance with current regulations. 2. SCALE OF CHARGES The following prices are established in accordance with the latest deliberation of the CRE (Commission de Régulation de l'energie - Energy Regulatory Commission) rendering a decision on changes in the price of use of natural gas transmission networks: - Base price - Transport Price on the Main Grid (PRP) - Transport Price on Regional Grid (PRR) - Delivery price - Set Delivery Price (only for PICs) - Hourly Capacity Delivery Price 2.1 Imbalance price Purchase Sale, Average price, Marginal Price, Discount and Premium In accordance with current regulatory provisions (European gas networks code and the latest deliberation of the Energy Regulatory Commission approving changes in balancing rules on the TIGF transmission network at 1 st April and 1 st October 2015, the Quantity of Energy Purchased/Sold on a given Day, as defined in the Operational Conditions (Appendix H.3.1 or Appendix H.3.2), is: a) When TIGF has not traded on the market for delivery on day D: i. purchased by the Transmission System Operator from the Shipper, at the Average Price of gas less a 2.5% discount ii. sold by the Transmission System Operator to the Shipper at the Average Price of gas plus a 2.5% premium For each day D, the Average Price of gas is the weighted average price of Within-Day transactions of all traders on the Powernext Gas Spot's TRS (Trading Region South) for delivery on day D, as calculated by Powernext. If Day D alls on a weekend and there are no Within-Day transactions for delivery on day D in the TRS, the Average Price is the weighted average of transactions made in the TRS by all traders on Powernext for the weekend maturity date that includes day D, as calculated by Powernext. If Day D is a Bank holiday in the sense of the Powernext calendar, and there are no Within-Day transactions for delivery on Day D in the TRS, the Average Price is the weighted average of Bank Holiday product transactions made in the TRS for the maturity date of Day D. 3

4 a) When TIGF and/or GRTgaz have traded on the market for delivery on day D: i. the Transmission System Operator purchases from the Shipper at the Marginal Selling Price ii. the Transmission System Operator sells to the Shipper at the Marginal Purchase Price The Marginal Selling Price is the lower of the two prices below: - the lower of all the sales of gas of TIGF and/or GRTgaz on the Powernext trading platform in respect of balancing for the gas day in question; OR - the Average Price of gas for the gas day in question, less a 2.5% discount The Marginal Purchase Price is the higher of the two prices below: - the higher of all the sales of gas of TIGF and/or GRTgaz on the Powernext trading platform in respect of balancing for the gas day in question; OR - the Average Price of gas for the gas day in question, plus a 2.5% premium The Transmission System Operator undertakes to factor in the Energy Quantities purchased/sold according to the arrangements specified in the Operational Terms (Appendix H.3.1 or Appendix H.3.2). 2.2 Neutral reference price The neutral reference price is applicable to the shippers who have subscribed the transport balancing service SET. For every single day eligible to the service, therefore on the days when the total imbalance of the network does not need any intervention from the TSO in the market, the shipper has the benefit of the linepack service to balance its portfolio. The shipper is consequently not exposed to the imbalance price. The monthly sum of imbalances on the days where the service is eligible is settled at the neutral reference price. This neutral reference price corresponds, for each shipper, to the weighted average of average prices for each day eligible to the SET with the corresponding volumes of imbalances compensated by the service. 2.3 Penalties for capacity overruns Overrun of the Daily Capacity at an Exit Point and at a Delivery Point Every day, penalties apply to identified daily exit capacity overruns on the main system and transport capacity overruns on the regional and delivery system. For that part of the overrun that is less than or equal to 3% of the subscribed daily capacity, no penalty is invoiced. For that part of the overrun in excess of 3%, the penalty calculation is based on the firm daily subscription price for daily capacity, in the following manner: 4

5 - for that share of the overrun between 3% and 10%, the penalty equals 20 times the firm daily subscription price for daily capacity; - for that share of the overrun greater than 10%, the penalty equals 40 times the firm daily subscription price for daily capacity Rules for calculating daily capacity overruns a) Overrun of the daily regional transport and delivery capacity for end consumers connected to the transmission network and the Regional Network Interconnection Points: For a given day, the daily capacity overrun taken into account equals the difference (if positive) between the delivered quantity of gas and the subscribed daily delivery capacity. b) Overrun of the daily regional transport and delivery capacity for the Transmission/Distribution Interconnection Point: For a given day, the daily capacity overrun taken into account equals the difference (if positive) between the following two values: - difference between the daily quantity of delivered gas and the corresponding daily delivery capacity, if this difference is positive, otherwise zero; - difference between the sum of the daily quantities delivered to "non-subscription" Delivery Points and the sum of the standardized capacities for "non-subscription" Delivery Points if this difference is positive, otherwise zero. c) Overrun of the main system's daily exit capacity: For a given day, the daily capacity overrun taken into account equals the difference (if positive) between the following two values: - difference between the daily quantity of delivered gas and the corresponding main system's daily exit capacity, if this difference is positive, otherwise zero; - difference between the sum of the daily quantities delivered in the exit zone to "non-subscription" Delivery Points and the sum, for the exit zone, of the standardized capacities for "non-subscription" Delivery Points if this difference is positive, otherwise zero. Should the Transmission System Operator exercise interruptibility, the above overrun calculations are made by reducing the interruptible capacity of the interrupted portion requested by the Transmission System Operator Hourly Capacity Overrun at the Delivery Point Every day, penalties are applied to hourly transport capacity overruns on the regional and delivery network, in order to supply end consumers connected to the transmission network. For a given day, the value of the hourly transport capacity overruns on the regional network taken into account equals the difference (if positive) between: the maximum value of the hourly average of the quantities delivered to the delivery point in question over four consecutive hours and the hourly capacity subscribed at the delivery point in question. If the Delivery Point Hourly Capacity Overrun (DPHCO) is less than or equal to ten percent (10%) of the hourly capacity noted at the Delivery Point in question, no penalty is owed. 5

6 If the Delivery Point Hourly Capacity Overrun (DPHCO) is greater than 10%, the penalty is based on the price of the daily subscription for hourly capacity, in the following manner: - for that share of the overrun between 10% and 20%, the penalty equals 45 times the daily subscription price for hourly capacity; - for that share of the overrun greater than 20%, the penalty equals 90 times the daily subscription price for hourly capacity. The identified Delivery Point hourly capacity equals the sum of the Hourly Delivery Capacities subscribed on an annual and monthly basis at a given Delivery Point. 2.4 Annual redistribution of penalties for capacity overruns At the latest in June of year N+1, TIGF undertakes to remit the amounts collected as penalties invoiced for capacity overruns for a given year N. The distribution is performed between shippers in proportion with the quantities of gas delivered to end consumers connected to the TIGF transmission network. 2.5 Distribution in respect of financial balancing neutrality The balancing result for a month M equals the difference between: TIGF's sales of natural gas on the Gas Trading Platform between the 1 st day of month M and the last day of month M, TIGF's sales of natural gas to shippers under transport contracts for Days between the 1 st day of month M and the last day of month M, TIGF's sale of the difference between quantities it purchased and quantities it sold in month M on the Gas Trading Platform under transport contracts, if this difference is positive. and TIGF's purchases of natural gas on the Gas Trading Platform between the 1 st day of month M and the last day of month M, TIGF's purchases of natural gas from shippers under transport contracts for Days between the 1st day of month M and the last day of month M, TIGF's purchase of the difference between quantities it sold and quantities it purchased in month M on the Gas Trading Platform under transport contracts, if this difference is positive. The Balancing Result for month M is shared out among the shippers having a current transport contract with TIGF in month M, prorated to the Daily Allocated Quantities at the Delivery Points for Days included the 1st day of month M and the last day of month M. 6

7 If the sum of the Balancing results in the calendar month is greater than zero (0), TIGF pays the Shipper its share of the said monthly sum. Otherwise, if the sum of the Balancing results in the calendar month is lower than zero (0), the Shipper pays TIGF its share of the said monthly sum. 2.6 Redistribution of surplus auction receipts In accordance with currently applicable CRE deliberations, every quarter TIGF redistributes the surplus receipts of auctions to shippers delivering in the TIGF zone at auctions of annual, quarterly, monthly and daily capacities at the Pirineos VIP and the North/South interconnection (from North to South). The amount redistributed for each shipper delivering in the TIGF zone equals the unit redistribution amount multiplied by its recorded supplies consumed eligible for redistribution in the period concerned. The unit amount for each auction equals the quotient of the surplus receipts generated at the auction by the reference value of the quantities eligible for redistribution. Redistributions are made via a credit note separate from the monthly invoice. 2.7 Price of access to the TRS over-the-counter market There is a notional gas trading point (the TRS) in the TRS balancing zone that allows shippers to trade quantities of gas. The price of access to the TRS over-the-counter market includes a fixed annual term of six thousand (6,000) euros and a term proportional to the quantities traded at 0.01/MWh to be paid by each counterparty. 2.8 Use It and Buy It (UBI) At the entry points and exit points to the PIRs, TIGF sells unsold capacities and subscribed capacities not nominated the day before for the following day in interruptible form every day at 1/240 th of the firm annual subscription price or 1/240 th of the firm summer subscription price plus the firm winter subscription price at these points. The UBI offer is available when at least 98% of the total firm capacity has been subscribed. 7
