NextDecade Signs MOU with Port of Cork to Develop FSRU and LNG Import Terminal Infrastructure

Parties Commit to Exclusive Collaboration for Delivery of up to 3
Million Tons of LNG per year into the Irish Gas Grid

THE WOODLANDS, Texas–(BUSINESS WIRE)–NextDecade, LLC (“NextDecade”), a liquefied natural gas (“LNG”)
development company focused on LNG export projects in the State of
Texas, announced it has signed a Memorandum of Understanding (“MOU”)
with the Port of Cork Company (“Port of Cork”) to advance a joint
business development opportunity in Ireland for a new Floating Storage
and Regasification Unit (“FSRU”) and associated LNG import terminal
infrastructure.

NextDecade and the Port of Cork are planning a joint public event at the
Port of Cork on August 2, 2017, to highlight the MOU and its potential
benefits for Ireland and its regional partners. NextDecade CEO Kathleen
Eisbrenner and Flex LNG CEO Jonathan Cook will meet with port officials
and discuss the opportunity with local industry and political leaders.

Under the terms of the MOU, the potential development at the Port of
Cork would receive LNG from NextDecade’s planned Rio Grande LNG
(“RGLNG”) project in South Texas. The development would provide
competitively priced energy solutions to Ireland and its regional
partners under long-term contracts. If constructed, the project would
substantially increase and diversify Ireland’s supply of natural gas.

The MOU commits the parties to undertake exclusive negotiations to
develop the LNG import project. A key seaport in the south of Ireland,
the Port of Cork is a sheltered, natural deepwater harbor capable of
handling large liquids and cargo ships of all sizes.

NextDecade’s RGLNG project is optimally located in close proximity to
associated and stranded gas resources in the Permian Basin and Eagle
Ford Shale. RGLNG and its associated Rio Bravo Pipeline, originating in
the Agua Dulce market area, are well-positioned among the second wave of
U.S. LNG projects. NextDecade believes the Port of Cork facility could
support imports of up to 3 mtpa from RGLNG.

In December 2016, NextDecade announced it had signed a Heads of
Agreement with FSRU provider FLEX LNG (Oslo Børs: FLNG) for the joint
development of a full value chain infrastructure solution utilizing FSRU
and dockside regasification import technology. FLEX LNG will be
supporting NextDecade to provide a fully integrated regas import
solution for the proposed LNG terminal at the Port of Cork. NextDecade
is in discussions with European energy companies to enter into long-term
purchase contracts for delivery of LNG at the Port of Cork.
Additionally, NextDecade will manage shipping from its proposed RGLNG
export facility at the Port of Brownsville in South Texas to the Port of
Cork.

On June 29, 2017, Harmony Merger Corp. (NASDAQ: HRMN) (“Harmony”) filed
a definitive proxy statement with the U.S. Securities and Exchange
Commission (“SEC”). The definitive proxy statement provides detailed
information regarding Harmony’s planned merger with NextDecade, which is
subject to approval of Harmony’s stockholders at a special meeting on
July 24, 2017. If approved by Harmony’s stockholders, following
consummation of the merger, NextDecade will be a publicly listed company
(NASDAQ: NEXT).
