OKLAHOMA CITY -- May 12, 2014

Access Midstream Partners, L.P. (NYSE:ACMP) announced today a major expansion
of the Utica East Ohio (UEO) midstream service complex in eastern Ohio. The
expansion will increase UEO's nameplate capacity to 1 billion cubic feet per
day (bcf/d) and allows for a processing capacity of over 1.1 bcf/d. UEO is a
joint venture owned 49% by Access Midstream, 30% by M3 Midstream LLC and 21%
by EV Energy Partners, L.P. (NASDAQ:EVEP).

Additional capacity is needed to meet new commitments from existing customers
Chesapeake Energy Corporation (NYSE:CHK), Total Gas & Power North America,
Enervest Ltd. and new customer, American Energy - Utica, LLC, an affiliate of
American Energy Partners, LP. These new commitments are expected to increase
UEO’s ultimate throughput by 70% over existing commitment levels.

The UEO complex will provide gathering, compression and dehydration services
for American Energy - Utica. The new long-term agreement between UEO and
American Energy - Utica includes a 145,000-acre area of mutual interest,
installation of 50 miles of gathering pipeline and compression services.

The UEO expansion will include the construction of a second processing train
at the Leesville, Ohio facility and extension of an existing high-pressure
pipeline from UEO’s Harrison Hub to Cardinal Gas Services’ (CGS) Archer
Compression Facility in Harrison County. Additional services also will be
added at Harrison Hub, including downstream liquids interconnects and expanded
propane and butane storage.

“Our investment in this expansion at UEO underscores our belief in the
long-term viability of the Utica Shale,” commented Mike Stice, CEO of Access
Midstream. “This growth not only significantly increases our capacity but will
improve access to downstream liquids markets. We are pleased to grow our
partnership with M3 and EV Energy Partners and enhance our ability to continue
providing excellent midstream solutions for our customers.”
