Confidential – Preliminary Draft PROJECT BRONCO CONFIDENTIAL DISCUSSION MATERIALS July 3, 2018 Project Bronco | Note, all analyses presented herein are preliminary and subject to change.

Confidential – Preliminary Draft SUMMARY OF INFORMATION PRESENTED HEREIN The materials presented herein assess the impacts of adjusting certain key transaction levers; in particular, Baird addresses the following topics: A comparison of key metrics implied by the current proposal (1) (1.6x AMGP shares for each AM unit) What are the impacts of modifying the exchange ratio to a higher level? What are the impacts of adding a cash component to the transaction? Approaches to the Series B valuation Summary of levers discussed and illustrative counter proposal Baird and Sidley are awaiting additional information related to proposed tax structure of the transaction. It is our intent to provide the special committee with an analysis of the proposed tax structure and its impacts to AR relative to other potential structures in a future meeting. Page 1 Project Bronco | (1) All references to the current proposal refer to the proposal letter dated June 8, 2018, addressing the potential acquisition of AM by AMGP.
