(d)Agreements The Partnership has entered into various agreements with Antero, as summarized below. Gathering and Compression In connection with the IPO on November 10, 2014, the Partnership entered in a 20-year gathering and compression agreement, whereby Antero has agreed to dedicate all of its current and future acreage in West Virginia, Ohio and Pennsylvania to us (other than the existing third-party commitments). The initial term of the gathering and compression agreement is 20 years from the date thereof and from year to year thereafter until terminated by either party. We also have an option to gather and compress natural gas produced by Antero on any acreage it acquires in the future outside of West Virginia, Ohio and Pennsylvania on the same terms and conditions. Under the gathering and compression agreement, we receive a low pressure gathering fee of $0.30 per Mcf, a high pressure gathering fee of $0.18 per Mcf, a compression fee of $0.18 per Mcf, and a condensate gathering fee of $4.00 per Bbl, in each case subject to CPI-based adjustments. If and to the extent Antero requests that we construct new high pressure lines and compressor stations, the gathering and compression agreement contains minimum volume commitments that require Antero to utilize or pay for 75% and 70% , respectively, of the capacity of such new construction. Additional high pressure lines and compressor stations installed on our own initiative are not subject to such volume commitments. Water Services Agreement In connection with the Water Acquisition on September 23, 2015, the Partnership entered a 20-year Water Services Agreement with Antero whereby we have agreed to provide certain fluid handling services to Antero within an area of dedication in defined service areas in Ohio and West Virginia and Antero agreed to pay monthly fees to us for all fluid handling services provided by us in accordance with the terms of the Water Services Agreement.

Under the agreement, Antero will pay a fixed fee of $3.685 per barrel in West Virginia and $3.635 per barrel in Ohio and all other locations for fresh water deliveries by pipeline directly to the well site, subject to annual CPI-based adjustments. Antero has committed to pay a fee on a minimum volume of fresh water deliveries in calendar years 2016 through 2019. Antero is obligated to pay a minimum volume fee to us in the event the aggregate volume of fresh water delivered to Antero under the Water Services Agreement is less than 90,000 barrels per day in 2016, 100,000 barrels per day in 2017 and 120,000 barrels per day in 2018 and 2019. Antero also agreed to pay us a fixed fee of $4.00 per barrel for waste water treatment at the advanced waste water treatment complex and a fee per barrel for waste water collected in trucks owned by the Partnership, in each case subject to annual CPI-based adjustments. Until such time as the advanced waste water treatment complex is placed into service or we operate our own fleet of trucks for transporting waste water, the Partnership will continue to contract with third parties to provide Antero flow back, produced water services, and high rate transfer services and Antero will reimburse us for our costs plus 3%.
