Stockholders of Blue Ridge Mountain Resources, Inc. Approve Combination with Eclipse Resources Corporation

Combination Now Approved by Boards of Directors and Stockholders of
Each Company

STATE COLLEGE, Pa. & IRVING, Texas–(BUSINESS WIRE)–Eclipse Resources Corporation (NYSE:ECR) (the “Company” or “Eclipse
Resources”) and Blue Ridge Mountain Resources, Inc. (OTCPK: BRMR) (“Blue
Ridge”) today announced that the stockholders of Blue Ridge, through the
delivery of written consents, have adopted the definitive merger
agreement under which Eclipse Resources and Blue Ridge will combine in
an all-stock transaction (the “Transaction”) and approved the merger and
the other transactions contemplated by the definitive merger agreement.
The Transaction has now been approved by the boards of directors and
stockholders of each company. Because Blue Ridge has received
stockholder written consents sufficient to adopt the merger agreement
and approve the merger and the other transactions contemplated by the
merger agreement, all stockholder written consents received by Blue
Ridge have become irrevocable.

Additionally, Blue Ridge has received requests from holders of the
requisite percentage of outstanding Blue Ridge common stock to cause the
Transaction to be a “drag transaction” for purposes of the Blue Ridge
stockholders agreement. As a result, Blue Ridge’s stockholders will be
required to take or refrain from taking certain actions, in each case,
in furtherance of the completion of the Transaction.

As previously disclosed, Blue Ridge stockholders will receive
consideration consisting of 4.4259 shares of Eclipse Resources common
stock for each share of Blue Ridge common stock, before adjustment for a
15-to-1 reverse stock split of Eclipse Resources common stock to be
effected concurrently with closing of the Transaction. Upon completion
of the merger, Eclipse Resources will change its name to Montage
Resources Corporation, and thereafter the Eclipse Resources common stock
will trade on the New York Stock Exchange under the symbol “MR”.

The closing of the Transaction remains subject to customary closing
conditions. Eclipse Resources and Blue Ridge expect that the Transaction
will be completed during the last week of February 2019.
