B.        The Code Share Agreement requires the Mesa Group to provide certain Flight Services and

C.        The Mesa Group and US Airways desire to amend the Code Share Agreement pursuant to the terms

NOW, THEREFORE, in consideration of the promises, covenants, representations and warranties hereinafter set forth, and for other valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, US Airways and the Mesa Group agree as set forth below: 

1.        The parties agree that the Code Share Agreement is amended by adding the following new
Section 7.11 (Section 7.10 having been previously added by the Fourth Amendment): 
  













	 	7.11	 Advance Payment of Certain Costs, Fees and Payments. Upon execution of this Ninth Amendment, US
Airways will pay Mesa a one-time lump-sum payment of $[***], representing an advance payment of the amounts otherwise due from US Airways under the Code Share Agreement
(the “Advance”), which Advance will be used by Mesa to pay certain of its costs and expenses arising under or relating to the Code Share Agreement. In exchange for the Advance US Airways will receive a credit of $[***] (together, the
“Credits”). In the event that Mesa contests or otherwise challenges or attempts to prevent the timely recoupment of the Credits on the dates specified above, US Airways may, at its option and upon 30 days’ written notice, [***],
notwithstanding any provisions of the Code Share Agreement to the contrary. From the date of the Advance until all remaining Credits have been applied hereunder, Mesa shall be and remain in full compliance with its material loan and lease
obligations, taken individually or in the aggregate. Upon request from US Airways, Mesa will provide appropriate certification of its compliance with the foregoing provision, and if Mesa is not in compliance with the foregoing provision as of the
date any payment from US Airways, such payment will be reduced by the full amount of any Credits not yet applied. 



2.        Effect. Except as set forth in this Ninth Amendment, all of the terms and conditions
of the Code Share Agreement shall remain in full force and effect and be applicable to this Ninth Amendment. 

3.        Counterparts. This Ninth Amendment may be executed in counterparts, all of which when
taken together shall be one and the same document. 
 4.        Entire Agreement. This Ninth
Amendment constitutes the entire agreement between the parties with respect to the subject matter hereof and supersedes all prior understandings with respect thereto.
