Three of MarkWest’s largest unitholders, Kayne Anderson Capital Advisors, L.P., Tortoise Capital Advisors, L.L.C., and, as previously announced, The Energy & Minerals Group, which cumulatively represent more than 15 percent of MarkWest’s outstanding units entitled to vote, have all entered into voting agreements to vote in favor of the transaction. The merger is also recommended by each of the boards of directors of MPC, MPLX and MarkWest, and the executive management of both partnerships strongly support the transaction and its revised terms.

“We are pleased that three of MarkWest’s top unitholders have agreed to support the combination and vote in favor of this revised offer,” said Gary R. Heminger, MPLX chairman and chief executive officer. “We look forward to consummating this transaction and delivering on the significant opportunities of the combined partnership.”

“This transaction will create long-term strategic value for our unitholders and customers through a combination of enhanced growth opportunities and significant parental support from Marathon Petroleum Corporation. This increased cash consideration from MPC further enhances the overall value of the transaction and our board and executive team recommend that MarkWest unitholders vote in favor of the merger proposal,” said Frank M. Semple, MarkWest chairman, president and chief executive officer.

The proposed transaction will combine MarkWest, the second-largest processor of natural gas in the United States and largest processor and fractionator in the Marcellus and Utica shale plays, with MPLX, a rapidly growing crude oil and refined products logistics partnership sponsored by MPC. The combination will create one of the largest master limited partnerships (MLPs), which is expected to generate a mid-20 percent compound annual distribution growth rate through 2019.

The transaction is subject to approval by MarkWest unitholders and other customary closing conditions and, subject to the satisfaction of those conditions, is expected to close in Dec. 2015. The date of the special meeting of MarkWest common unitholders is Dec. 1, 2015. MarkWest unitholders of record as of Oct. 5, 2015, will be entitled to vote on approval of the merger and the associated proposals.

MarkWest unitholders are urged to vote “FOR” the merger and related matters and submit their proxy as promptly as possible, either by telephone, via the internet or by marking, signing and dating the proxy card that was provided to unitholders along with the proxy statement and prospectus. If you abstain from voting, fail to cast your vote in person or by proxy or fail to give voting instructions to your broker, bank or other nominee, it will have the same effect as a vote “AGAINST” the merger proposal.

MarkWest is mailing supplemental proxy materials to its unitholders.

Your vote is very important regardless of the number of MarkWest common units you own. The merger cannot be completed unless the holders of at least a majority of the outstanding MarkWest common units, voting together as a single class, vote for the proposal to approve the merger agreement and the transactions contemplated thereby at the special meeting of MarkWest common unitholders (the “Merger Proposal”). At the special meeting, MarkWest common unitholders will also vote on an advisory compensation proposal (the “Advisory Compensation Proposal”) and on a proposal to adjourn the special meeting, if necessary, to solicit additional proxies if there are not sufficient votes to approve the merger agreement and transactions contemplated thereby at the time of the special meeting (the “Adjournment Proposal”).

If you have already voted and would like to revoke your proxy or change your vote, you may do so at any time before the special meeting of MarkWest common unitholders. If you are a MarkWest common unitholder of record, you may revoke your proxy and/or change your vote, or if you have not yet voted you may do so, at any time before 11:59 p.m. Eastern Time on Nov. 30, 2015 (the “Telephone/Internet Deadline”) or before the polls close at the MarkWest special meeting by (1) sending a written notice, which is received prior to the Telephone/Internet Deadline, to MarkWest at 1515 Arapahoe Street, Tower 1, Suite 1600, Denver, Colorado 80202, Attn: Corporate Secretary, that bears a date later than the date of the proxy and states that you revoke your proxy, (2) submitting a valid, later-date proxy by mail, telephone or Internet that is received prior to the Telephone/Internet Deadline or (3) attending the special meeting of MarkWest common unitholders and voting by ballot in person (your attendance at the MarkWest special meeting will not, by itself, revoke any proxy that you have previously given). If you hold your MarkWest common units in “street name,” you should follow the instructions of your broker, bank or other nominee regarding the revocation of proxies. If your broker allows you to submit a proxy via the Internet or by telephone, you may be able to change your vote by submitting a new proxy via the Internet or by telephone or by mail.
