Exhibit 10.1

SECOND AMENDMENT TO
GAS GATHERING AGREEMENT
[Alliance]
This Second Amendment to the Gas Gathering Agreement (the “Second Amendment”) is
executed July 9, 2014 but effective as of June 1, 2014 (the “Effective Date”),
by and between Quicksilver Resources Inc. (“Quicksilver”) and TG Barnett
Resources LP (“TG”) (Quicksilver and TG are collectively referred to herein as
“Producer”), and Cowtown Pipeline Partners L.P. (“Gatherer”).
WHEREAS, Producer and Gatherer are parties to the Gas Gathering Agreement, dated
as of December 1, 2009, as amended by Amendment to Gas Gathering Agreement dated
October 1, 2010 (collectively referred to as the “Alliance Agreement”);
WHEREAS, by virtue of that certain Assignment, Bill of Sale and Conveyance, by
and between Quicksilver and TG, dated the 30th day of April 2013, effective
September 1, 2012, TG has been assigned an interest in the Alliance Agreement;
and
WHEREAS, the parties desire to amend the terms of the Alliance Agreement as
provided in this Second Amendment;
NOW, THEREFORE, in consideration of the mutual premises and benefits contained
herein, the adequacy, receipt and sufficiency of which are hereby acknowledged,
Producer and Gatherer amend the terms of the Alliance Agreement, as follows:
1.
Article 1, Definitions is amended as follows:

Section m., “Escalation Date” shall be deleted in its entirety and the following
substituted in its place: “m. “Escalation Date”, except for the Lift Gas Fee,
shall mean January 1st 2015 and each January 1st thereafter during the Term. The
Escalation Date for the Lift Gas Fee shall mean January 1, 2016 and each January
1st thereafter during the Term.”

2.
Article 1, Definitions is amended to add the following definition:

“oo.    “Lift Gas Volume” is the amount of Gas, reserved by Producer under
Section 3.2, used by Producer for gas lift operations in the Contract Area,
measured in MCFs at the existing Alliance CMU meter station number ALSA020MU.”

3.
Article 11, Fees is amended by replacing the first sentence in 11.1 with the
following:

“Producer shall pay to the Gatherer 59.355 cents ($0.59355) multiplied by the
positive difference between (i) the total volume of Producer’s Gas (measured in
Mcf) metered at the Receipt Point(s) and (ii) the Lift Gas Volume, subject to
adjustment as provided in Section 11.2 (such rate, as so adjusted, the
“Gathering Fee”).”

--------------------------------------------------------------------------------

4.
Article 11, Fees is amended to add the following:

“11.3    Producer shall pay to Gatherer twenty cents ($.20) per Mcf multiplied
by the Lift Gas Volume pursuant to this Agreement, subject to adjustment as
provided in Section 11.2 (such rate, as so adjusted, the “Lift Gas Fee”).
“11.4 For the period beginning on July 1, 2014 and ending on June 30, 2016,
Gatherer shall work with Producer to evaluate the purchase of all or a portion
of Producer’s existing and future gas lift systems at Alliance. Regardless of
whether the parties are able to reach a mutual agreement as to such potential
purchase(s), Gatherer shall have the Exclusive Right to provide Producer’s gas
lift needs for the remaining Term of the Alliance Agreement. As used herein, the
term “Exclusive Right” is defined to mean that (i) Gatherer shall be the
exclusive provider of gas lift services to Producer at the existing and any
future points delivered into Producer’s existing and future gas lift systems,
and (ii) Producer shall negotiate with no other party and deal exclusively with
Gatherer to potentially provide any alternative gas lift method which could
eliminate or materially alter the then existing manner in which Gatherer
supplies lift gas to Producer at existing and future wells. This Exclusive Right
is not intended to hinder Producer from alternative non gas lift methods
(including, but not limited to, plungers or other similar lifting technologies)
at any individual well (including each such well for which there is no gas lift
pipeline connection as of the date hereof), where such lift gas being provided
or to be provided, as applicable by Gatherer is not or will not be adequate at
such particular well to provide Producer’s lift requirements. Producer shall
retain sole discretion in the deployment of these alternative non gas lift
techniques; provided in the event that Producer employs such artificial non gas
lift techniques on a well, it will notify Gatherer within a commercially
reasonable time frame.”
Except as amended by this Second Amendment, the terms and provisions of the
Alliance Agreement are and shall remain in full force and effect.
Capitalized terms used but not otherwise defined herein shall have the meaning
given such terms in the Alliance Agreement.
