FORWARD-LOOKING STATEMENTS This presentation contains forward-looking statements. All statements, other than statements of historical facts, included in this presentation that address activities, events or developments that Antero Midstream Partners LP, and its subsidiaries (collectively, the “Partnership”) expect, believe or anticipate will or may occur in the future are forward - looking statements. The words “believe,” “expect,” “anticipate,” “plan,” “intend,” “estimate,” “project,” “foresee,” “should,” “would,” “could,” or other similar expr essions are intended to identify forward-looking statements. However, the absence of these words does not mean that the statements are not forward-looking. Without limiting the generality of the foregoing, forward-looking statements contained in this presentation specifically include expectations of plans, strategies, objectives, and anticipated financial and operating results of the Partnership and Antero Resources Corporation (“Antero Resources”). These statements are based on certain assumptions made by the Partnership and Antero Resources based on management’s experience and perception of historical trends, current conditions, anticipated future developments and other factors believed to be appropriate. Such statements are subject to a number of assumptions, risks and uncertainties, many of which are beyond the control of the Partnership, which may cause actual results to differ materially from those implied or expressed by the forward-looking statements. These include the factors discussed or referenced under the heading “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2014 and in the Partnership’s subsequent filings with the SEC. The Partnership cautions you that these forward-looking statements are subject to risks and uncertainties that may cause these statements to be inaccurate, and readers are cautioned not to place undue reliance on such statements. These risks include, but are not limited to, Antero Resources’ ability to meet its drilling and development plan, commodity price volatility, inflatio n, environmental risks, drilling and completion and other operating risks, regulatory changes, the uncertainty inherent in projecting future rates of production, cash flow and access to capital, the timing of development expenditures, and the other risks discussed or referenced under the heading “Item 1A. Risk Factors” in the Partnership’s Annual Report on Form 10-K for the year ended December 31, 2014 and in the Partnership’s subsequent filings with the SEC. Any forward-looking statement speaks only as of the date on which such statement is made, and the Partnership undertakes no obligation to correct or update any forward-looking statement, whether as a result of new information, future events or otherwise, except as required by applicable law. Antero Resources Corporation is denoted as “AR” and Antero Midstream Partners LP is denoted as “AM” in the presentation, which are their respective New York Stock Exchange ticker symbols. 1

ANTERO ADVANCED WASTEWATER TREATMENT COMPLEX Advanced Wastewater Treatment Complex Water Asset System Map • Veolia Water Technologies, Inc. will design and build the largest advanced wastewater treatment complex in Appalachia to support the growing needs for the treatment and recycling of flowback and produced water for Antero Resources ‒ Additional opportunities to treat volumes from third party operators • Complex will be strategically located in the core of the Marcellus Shale in West Virginia and will aggregate both Marcellus and Utica Shale flowback and produced water volumes • Facility will produce fresh water that meets stringent fresh water quality specifications. This allows it to be returned directly into Antero’s existing freshwater delivery system to provide water for both Marcellus and Utica well completions in West Virginia ‒ Reliable year-round water source for drilling and completion activities ‒ Reduces environmental impact by eliminating hundreds of thousands of water truckloads every year Advanced Wastewater Treatment Complex Capital expenditures ($ million) (1) ~$275 ~$55 – $65 Standalone EBITDA at 100% utilization (2) ~4x – 5x Implied investment to standalone EBITDA build-out multiple Per well savings to Antero Resources ~$150,000 In service date Late 2017 Antero advanced wastewater treatment facility Operating capacity (Bbl/d) 60,000 connects to Antero freshwater delivery system Operating agreement 10 Years 2 1) Includes capital to construct pipeline to connect facility to freshwater delivery system. 2) Standalone EBITDA projection assumes inter-company fixed fee for recycling of $4.00 per barrel and 60,000 barrels per day of capacity. Does not include potential sales of marketable byproducts.
