It asks them to trust that founder’s kids. And their kids’ kids. And their grandkid’s kids…It raises the prospect that control over our public companies, and ultimately of Main Street’s retirement savings, will be forever held by a small, elite group of corporate insiders—who will pass that power down to their heirs. I cannot see how to square that with our nation’s foundational ideas. In America, we don’t inherit power, and we don’t hold power forever…Now, our public markets aren’t our government, but our country’s spirit of democratic accountability has long animated how we think about economics” – Robert Jackson, U.S. Securities and Exchange Commissioner, February 15, 2018

We believe that companies that look to add or already have dual or multiple class share structures should review these structures on a regular basis or as company circumstances change, and receive shareholder approval of their capital structure on a periodic basis via a management proposal on the company’s proxy. The proposal should give unaffiliated shareholders the opportunity to affirm the current structure or establish mechanisms to end or phase out controlling structures at the appropriate time, while minimizing costs to shareholders.” – BlackRock’s 2018 Proxy Voting Guidelines for U.S. Securities Passive 40% Active 60% ...2006...

Morgan: “The retained cash and pricing improvements should allow AROC to self-fund growth capex and de-lever, thereby eliminating capital markets dependency…. Those bullish, while not thrilled with the AROC equity valuation used, appreciated the alignment of interests, improved trading liquidity/cost of capital and removal of distractions from an otherwise attractive cyclical recovery story. APLP holders seemed to universally agree with the merger strategic rationale, but some income-oriented investors may reallocate capital to higher yielding securities…” Enhance cash coverage Improve credit profile Simplify capital structure Reduce cost of capital LP coverage ~0.7x No debt capacity or access to equity Transaction implied distribution cut, though distributions paid to GP entity remain largely intact pro formaBrad Baron (CEO): “Fundamental shift … in the makeup of the investor base for MLPs, which has tightened MLP equity markets and access to equity … paradigm shift in market sentiment away from strong growth fueled by continuous equity issuances to [one] that favors strong distribution coverage and rewards MLPs for low leverage, less dependency on the equity markets, and increased self-funding of capital projects” Source: Company press releases and Wall Street research 37 Market Commentary on Simplifications, Arkose Family, and Governance

The improvement of Williams Partners’ cost of capital and simplified organizational structure will better align GP and LP interests as well as solidify Williams Partners’ investment-grade credit ratings.”Goldman Sachs Research: “Overall, we believe this transaction is a rational move for HEP given that it would reduce its IDR burden. Despite the potential improvement in the cost of equity… HEP’s higher distribution yield implies a relative disadvantage to midstream peers … in competing for projects and 3rd party M&A.” No DPU growth Limited IDR growth No remaining drop downs High MLP cost of equity capitalHigh IDR take Limited DPU growth High MLP cost of equity capital No identified drop down assets Preference to simplify Enbridge family structureBill Yardley (President and Chairman of the Board of SEP): “Today’s transaction improves SEP’s long-term value proposition. With an improved cost of capital, we are even better positioned to improve and extend SEP’s distribution growth outlook through organic growth projects, potential future drop downs from Enbridge and third party acquisitions.” Source: Company press releases and Wall Street research 38 Market Commentary on Simplifications, Arkose Family, and Governance

PRELIMINARY CONFIDENTIAL DRAFT – FOR DISCUSSION PURPOSES ONLY Notable Analyst Commentary Around Recent Arkose Events and Developments (1/2)Evercore, 15-Feb-2018: We see the market continuing to grapple with the (post 2020, unhedged, E&P standalone) outlook for growth and mar gins, while improved capital efficiency and a repeatable, predictable development plan are central to the bull case. We believe Upstream’s margins could see significant pressure due to higher-cost pipeline tariffs and excess firm transport (FT) capacity cannibalizing improved end market prices through 2018, unless the company can successfully release excess capacity or renegotiate terms wit h pipeline operators on volumes or price. (SunTrust, 14-Feb-2018) Goldman Sachs, 14-Feb-2018: We believe that while Upstream possesses an attractive hedge portfolio that provides cash flow/produ ction growth visibility through 2020, and its ability to meet long-term guidance (20% production growth through 2020; 15% production growth in 2021-22) at attractive capital efficiency will be key in what we expect to be a tougher environment for Appalachia gas in the early 2020s. Guggenheim, 14-Feb-2018: We think the most important update from the analyst day was the 2021-22 Midstream distribution growth guidance of 20%, which we believe was above expectations of 10-15%. The drilling schedule required to keep up such a growth rate has become a flashpoint and there is the possibility that growth in the out years does slow. However, we don't really believe at current levels that Midstream is getting full credit from investors for this growth anyway. BMO Capital Markets, 23-Jan-2018: As such, while 2018-19 are still transition years for E&P, the "clean" FCF and debt-adjusted production growth improves meaningfully in 2020E. We think demonstrating that E&P can achieve sustainable growth within cash flow is important to receiving full sum-of-the-parts value.SunTrust, 14-Feb-2018: Operational updates were positive with LOE and the WGL contract issues both expected to be in the rear-view mirror, and strong Utica well results further bolstering management's confidence in the formation; we would note CNX Resources' outperfor mance today is likely due to the proximity of its acreage. BMO Capital Markets, 23-Jan-2018: Upstream has been one of the better positive rate-of-change stories among natural gas E&Ps, as advanced completions have driven a significant improvement in lateral adjusted well productivity, while its acreage position allows fo r more capital efficient, longer laterals than West Virginia Marcellus peers. While 2017 for West Virginia isn’t available, we’d note that Upstream’s 2016 vintage well productivity increased by 30% and it now leads peers on a lateral adjusted basis. Baird, 26-Feb-2018: It appears the market is baking in a large Upstream sale of Midstream units…However we think the ultimate ri sk to Midstream proves low because a large Midstream unit sale would hurt, not help, Upstream's NAV by suppressing the pricing on Midstream units further. SunTrust, 11-Feb-2018: The company gave detailed guidance including a five year outlook at its recent analyst day, and as such we would expect minimal changes to plans. That being said, with the shift to FCF positive expected in the near-term, we anticipate a multitude of questions on the use of proceeds. Given the high hurdle rate of existing opportunities, we look for management to lean more towards acceleration (lik ely in the Marcellus, not Utica) and returning shareholder value (previously stated it has no plans to use its ATM) and away from acquisitions. Guggenheim, 1-Feb-2018: Upstream’s first analyst meeting since the IPO in 2013 tweaked some details but largely left the midstream-biased strategy intact. There was better capital efficiency in the long-term guide but upstream shareholders were unimpressed by a strategy that prioritized growth over free cash flows in an over-supplied basin. We believe the most direct and disruptive option is to reduce upstream growth from a current rate of 15 – 20% annually and return the cash to shareholders. But any significant adjustment would be a shock to midstream valuations and midstream distributions are a “third rail” that management and vested parties are reluctant to touch, in our view. Another option is to monetize a 53% ownership in Midstream and use some of the proceeds for a share buyback.

PRELIMINARY CONFIDENTIAL DRAFT – FOR DISCUSSION PURPOSES ONLY Notable Analyst Commentary Around Recent Arkose Events and Developments (2/2)Scotia Howard Weil, 26-Feb-2018: While it is difficult to predict the possible outcomes of a transaction, we would note GP is still in its early days, having gone public in the 1H17. In 2017, Midstream payed out ~22% of its distributable cash flow to the GP in the form of IDRs. For comparison, EQGP receives 33% of EQM’s total distributions. Baird, 26-Feb-2018: If each entity has a real conflicts committee seeking its own interests, on structure, Upstream likely will find its options limited, Midstream will choose to stand pat (paying up for GP would be detrimental, as shown in our core distribution analysis (Link)) , and GP will choose to stand pat (no reason to dilute the growth plan by bringing on debt). Guggenheim, 1-Feb-2018: A broader corporate shift would be for Upstream to cut their drilling program, shed lower tier acreage a nd their FT commitments, and slow production growth. This would lead Midstream/GP to cut their distribution growth rate and cause a re -rate of both stocks, but we note that we don’t think Midstream is getting full credit for their growth anyway. An IDR restructuring would be easier to execute than a major slowdown in drilling and production because they could then maintain growth and not impact their FT/processing/fractionation commitmen ts and JVs.Evercore, 15-Feb-2018: Our sense is that management is attuned to investor calls to action and has highlighted Upstream equity ownership and shareholder-friendly compensation metrics. Beyond addressing structure and some of the perceived conflicts of interest we see ma rket skepticism around what tangible steps can be taken toward value unlock. Raymond James, 15-Feb-2018: Eliminating Midstream’s IDR’s would result in both Upstream and management owning a substantial amount of Midstream units and at least improve the perceived issue of alignment of GP/LP incentives between Upstream and management. Wells Fargo, 16-Feb-2018: We believe Midstream’s unit price decline [since the announcement of a strategic review] reflects investors’ concerns regarding the potential outcome of the strategic review. While there are many potential permutations, some of which may be ne ar-term dilutive to either Midstream or GP, our long-term positive outlook on the partnerships is unchanged. Midstream and GP remain well positioned to del iver industry leading distribution growth, driven by organic investments (without the need to access the equity capital market) in support of Upstream’s identified 5-year development plan. Raymond James, 15-Feb-2018: The Arkose franchise is both in a better current financial position and/or earlier in the life-cycle than most of the entities that have undergone a simplification of the GP/LP structure, when the GP burden has become significantly detrimental to the u nderlying LP cost of equity capital. In fact, Midstream’s best-in-class distribution/unit growth rate is the main reason this issue becomes noticeable over the next few years at all (i.e. based on the aforementioned Midstream distribution CAGR, Midstream’s cash flow to the GP accelerates from ~26% now to ~40% by 2020). MUFG, 19-Jan-2018: What we fear is the Upstream narrative is already played out. Upstream has already spun-off two entities that return capital to an investor: Midstream and GP. So, when faced with the option to invest in the Arkose story, the incremental investor has the optionality to expose themselves to the growth proposition in a security that returns capital.
