TRANSPORTATION CAPACITY ECONOMICS $8.00 The average AGT to TETCO M3 basis after November 2018 is $0.88/Dth, which is less than the cost of new pipeline capacity (assumed to be the Atlantic Bridge recourse rate of $1.83/Dth). $7.00 $6.00 Gas Price, $/Dth $5.00 $4.00 $3.00 $2.00 $1.00 $ Note: Price forecasts reflect the addition of the contracted expansions (AIM and Atlantic Bridge) on AGT.

THE RELIABILITY PREMIUM FOR PEAK MARKETS The reliability premium is the premium that a market would pay for 365-day FT capacity to access cheaper Marcellus gas supply to supply short-term (30 or 60 days) peak demand. $40.00 $35.00 Daily Gas Volume, Dth $30.00 $25.00 $20.00 $15.00 $10.00 $5.00 $ 30-Day Service 60-Day Service 30 day Equiv.

The total transportation cost (365-day FT) that was used for Marcellus to the AGT market was $1.83/Dth, which is the Atlantic Bridge recourse rate. 30-day and 60-day base-load services can be provided to the market using imported LNG. 10

WORLDWIDE LNG DEMAND AND CAPACITY 70 The current demand/capacity gap of ~5 Bcfd is expected to double to ~10 Bcfd by 2025, which will dampen LNG price increases during that period. 60 50 LNG Volume, Bcfd 40 30 20 10 0 2016 2017 2018 2019 2020 2021 2022 2023 2024 2025 Worldwide LNG Demand Worldwide Liquefaction Capacity Source: IHS 11

WORLDWIDE LNG PRICE FORECAST $16.00 The long-term LNG price forecast indicates that both Atlantic and Pacific basin LNG will be much more cost effective for serving peak-day demand than new year-round long-term pipeline capacity into New England. $14.00 $12.00 LNG Price, $/Dth $10.00 $8.00 $6.00 $4.00 $2.00 $0.00 2016 2017 2018 2019 2020 2021 2022 2023 2024 2025 Japan South Korea Taiwan United Kingdom Germany Spain Source: IHS January 2016 Price Forecast 12

REPSOL S WINTER PEAKING SERVICE Mitigates Gas Supply Risk During Peak Demand Periods During the contract term, the counter-party has a call option for gas supply from Repsol. The call option includes a maximum daily quantity ( MDQ ) limit as well as an aggregate quantity limitation ( AQL ) on the total volume that the counter-party can purchase during the term of the contract. The call option includes a demand charge / commodity charge price structure that is based on anticipated market prices and volatility for gas in the region. The delivery points for the gas would be mutually agreed by the parties. Multi-month winter base-load service can also be provided with appropriate modifications to the pricing structure. 14

REPSOL S WINTER PEAKING SERVICE Multiple Benefits to New England & Maritimes CA LNG Supply Availability The well-documented worldwide LNG supply glut will make New England an attractive destination for LNG cargoes for the foreseeable future. Immediate Service Availability (Facilities are already in place.) No facility siting risk No project execution risk No permitting risk No cost overrun risk Definitive Capacity Costs Capacity contracts are in place and fees are fixed. Flexible Contract Term While long-term (>5 years) contracts are not required, they are available under various structures that provide competitive solutions. Reliability Peaking service is a firm natural gas delivery obligation. Repsol has never failed to meet a firm natural gas delivery obligation. 15

FINAL THOUGHTS Effective utilization of existing natural gas infrastructure (LNG storage/regas and pipelines) to serve short-term winter peak gas demand, coupled with infrastructure additions for long-term baseload market growth, is the most responsible and economic solution for gas supply reliability in New England. Given the recent decline in worldwide LNG prices coupled with the abundant new LNG supply sources that will come on line in the next few years, LNG will remain a competitive and reliable gas supply source for New England and Maritimes Canada. Repsol has successfully provided winter peak gas supply services to the New England market for several years now, and it is poised to provide multi-year peaking services in lieu of expensive long-term (15+ year) pipeline expansions. 16
