THIS FIRST AMENDMENT TO AIRCRAFT TIME SHARING AGREEMENT (this “First Amendment”)
is made as of the 29th day of July, 2010 by and between Qwest Corporation
(“Lessor”) and Edward A. Mueller (“Lessee”) and amends the Aircraft Time Sharing
Agreement entered into by the Lessor and Lessee on December 1, 2008 and
effective January 1, 2009 through December 31, 2011. Capitalized terms used but
not defined herein shall have their respective meanings as defined in the
Aircraft Time Sharing Agreement. In the event of any inconsistency between the
terms of the Aircraft Time Sharing Agreement and the terms of this First
Amendment, the terms of this First Amendment shall prevail. All terms and
conditions of the Agreement not specifically amended or supplemented herein,
shall remain unchanged and in full force and effect.

WITNESSETH:

WHEREAS, Lessor and Lessee have heretofore entered into a Aircraft Time Sharing
Agreement dated December 1, 2008 (the “Agreement”) wherein Lessor agreed to
provide Lessee with the periodic use of certain Lessor owned or operated
aircraft from January 1, 2009 through December 31, 2011 with flight crew on a
non-exclusive time sharing basis as defined in Section 91.501(c)(1) of the
Federal Aviation Regulations (“FAR”);

WHEREAS, the Agreement identified two Lessor aircraft in Exhibit A and Exhibit B
available for use by Lessee under the Agreement;

WHEREAS, Lessor has recently purchased a third aircraft which it desires to make
available for use by the Lessee under the Agreement; and

WHEREAS, Lessor and Lessee have agreed to modify the Agreement as hereinafter
set forth in this First Amendment.

NOW, THEREFORE, in consideration of the above recitals, and the mutual covenants
herein contained and other good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged by both parties, it is mutually
understood and agreed that the Agreement be amended a follows:

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

  1. From and after the date hereof, the first recital on Page 1 of the

engines and components as described in the Aircraft Subject to the Time Sharing
Agreement attached hereto and made a part hereof, as Exhibit A and C;

 

  2. From and after the date hereof, the fifth recital on Page 2 of the

  3. From and after the date hereof, Paragraph 20 of the Agreement shall be
deleted in its entirety and replaced as follows:

Legal title to the Aircraft in Exhibits A and C shall remain in the Lessor at
all times. Lessor has the right of possession to the Aircraft in Exhibit B

transfer of Lessor’s possessory rights to any Aircraft.

 

  4. From and after the date hereof, Exhibit A of the Agreement is deleted in
its entirety and replaced as provided in new Exhibit A (attached).
