Tellurian will sell and issue to TOTAL, 35,384,615 shares of

with the SPA, Tellurian, Magellan Petroleum Corporation, a

Merger Agreement Amendment) to the previously
announced Agreement and Plan of Merger, dated as of August2, 2016
and amended on November23, 2016, among those parties (the
Merger Agreement). Among other things, the
Merger Agreement Amendment (i)permits Tellurian to enter into the
SPA and issue the Tellurian Shares to TOTAL, (ii)increases the
maximum number of shares of Tellurian common stock (or its
equivalent) issuable to current and prospective employees of
Tellurian under the Tellurian 2016 Omnibus Incentive Plan between
August2, 2016 and the closing of the merger contemplated by the
Merger Agreement (the Merger) from 10,000,000 to
13,000,000, (iii)requires Magellan to appoint one board designee
of TOTAL to the board of directors of Magellan effective upon the
closing of the Merger, and (iv)extends the Outside Date (as
defined in the Merger Agreement) from January31, 2017 to
February28, 2017.

The Merger Agreement Amendment has been approved by the board of
directors of each of Magellan and Tellurian. The closing of the
transactions contemplated by the SPA is subject to customary
closing conditions, including, among others, the accuracy of each
partys representations and warranties contained in the SPA and
each partys compliance with its covenants and agreements
contained in the SPA in all material respects.

Assuming the satisfaction of the closing conditions, Magellan and
Tellurian expect the transactions contemplated by the SPA to
close on January3, 2017.

At the closing of the transactions contemplated by the SPA,
(i)Magellan, TOTAL, Charif Souki, the Souki Family 2016 Trust,

guaranty and support agreement, to which Magellan will,
contingent on the closing of the Merger, guarantee to TOTAL the
performance of all of the obligations of Tellurian in connection
with the SPA (the Guaranty and Support
Agreement); and (iii)Tellurian and TOTAL will enter into
a pre-emptive rights agreement, to which TOTAL will be granted a
right to purchase its pro rata portion of any new equity
securities that Tellurian may issue to a third party on the same
terms and conditions as such equity securities are offered and
sold to such party, subject to certain excepted offerings (the
Pre-emptive Rights Agreement).

In connection with the SPA, (i)following the closing of the

the Tellurian Shares, with certain registration rights relating
to the Magellan common stock that TOTAL will receive upon the
closing of the Merger.
