Commodity Exposure Enable targets fee-based contracts on a firm basis, when possible

Some gathering and processing contracts have provisions to protect against low

commodity price environments and volume decreases

Commodity sensitivities for second quarter 2015 through fourth quarter 2015, including the

impact of hedges:

A 10% increase or decrease in the price of natural gas from forecasted levels would result in an increase or decrease

of approximately $6 million in gross margin

A 10% increase or decrease in the price of NGLs and condensate from forecasted levels would result in an increase

or decrease of approximately $1 million in gross margin
