    AMENDMENT NO. 1 TO AIR TRANSPORTATION CHARTER AGREEMENT    
    

        This Amendment No. 1 to Air Transportation Charter Agreement ("Amendment") is
made as of the 30th day of April, 2009, by and between Allegiant Air, LLC, a Nevada limited liability company with principal
offices at 8360 South Durango Drive, Las Vegas, Nevada 89113 ("Allegiant"), and Harrah's Operating Company, Inc., a Delaware corporation with
principal offices at One Harrah's Court, Las Vegas, Nevada 89119 ("Charterer") (Allegiant and Charterer shall each also be referred to as a "Party" or collectively as the "Parties"). 

        WHEREAS, Allegiant and Charterer are parties to that certain Air Transportation Charter Agreement executed on October 31, 2008 (the
"Agreement"), and 

        WHEREAS, Allegiant and Charterer have agreed that it is in the interest of both Parties to enter into an amendment to the Agreement, and 

        WHEREAS, Allegiant and Charterer have agreed to amend the Agreement pursuant to Section 28.7 thereof; 

        THEREFORE, in consideration of the promises, covenants, and provisions below and the recitals above, Allegiant and Charterer hereby amend
the Agreement as follows: 

        1.     Pursuant
to the Agreement, Allegiant bases one MD-87 aircraft at Reno/Tahoe International Airport, Reno, Nevada ("RNO") for the operation of charter flights
to and from RNO as set forth in the Agreement. This Amendment affects only the RNO-based aircraft (the "RNO Aircraft"); all operations of aircraft based at other locations continue to be
subject to the terms and conditions of the Agreement without reference to this Amendment. 

        2.     Notwithstanding
anything to the contrary in the Agreement, in the case of all flights that (i) operate to or from RNO or
are positioning flights (also known as ferry flights) associated with the operation of such flights, (ii) utilize the RNO Aircraft, and
(iii) operate after June 30, 2009 but before January 1, 2010, the following shall apply: 

        (a)   The
Price for Services shall be fixed at [...***...] per Actual Block Hour flown and shall not be subject to adjustment based upon the price of

        (b)   Harrah's
shall pay Allegiant for all Actual Block Hours flown, provided that in the event the Actual Block Hours flown in any calendar month are less than the minimum
number of hours specified below, Harrah's shall pay Allegiant for the number of hours specified below for that month: 

 

 

			
	 July 2009:
	 	[...***...]
	 August 2009:
	 	[...***...]
	 September 2009:
	 	[...***...]
	 October 2009:
	 	[...***...]
	 November 2009:
	 	[...***...]
	 December 2009:
	 	[...***...]

 

 
        3.     This

proposal to Allegiant no later than August 3, 2009. The Parties agree that any negotiation of such proposal shall be accomplished during August 2009 and that to the extent agreement on the
proposal or any counterproposal is reached, the resulting amendment shall be executed no later than September 1, 2009; failing which, the Agreement, as amended by this Amendment No. 1,
shall be unaffected by the proposal or any counterproposal. 

        5.     Except
as set forth in this Amendment, the terms and conditions of the Agreement shall remain in full force and effect at all times. Capitalized terms that appear in this
Amendment and that are defined in the Agreement have same meaning in both documents.

    AMENDMENT NO. 2 TO AIR TRANSPORTATION CHARTER AGREEMENT    
    

        This Amendment No. 2 to Air Transportation Charter Agreement ("Amendment") is
made as of the 6th day of November, 2009, by and between Allegiant Air, LLC, a Nevada limited liability company with
principal offices at 8360 South Durango Drive, Las Vegas, Nevada 89113 ("Allegiant"), and Harrah's Operating Company, Inc., a Delaware
corporation with principal offices at One Harrah's Court, Las Vegas, Nevada 89119 ("Charterer") (Allegiant and Charterer shall each also be referred to as a "Party" or collectively as the "Parties"). 

        WHEREAS, Allegiant and Charterer are parties to that certain Air Transportation Charter Agreement executed on October 31, 2008, as
amended by Amendment No. 1 thereto (collectively, the "Agreement"), and 

        WHEREAS, Allegiant and Charterer have agreed that it is in the interest of both Parties to further amend the Agreement, and 

        WHEREAS, Allegiant and Charterer have agreed to amend the Agreement pursuant to Section 28.7 thereof; 

        THEREFORE, in consideration of the promises, covenants, and provisions below and the recitals above, Allegiant and Charterer hereby amend
the Agreement as follows: 

        1.     Pursuant
to the Agreement, Allegiant currently bases one MD-87 aircraft at Reno/Tahoe International Airport, Reno, Nevada ("RNO") for the operation of charter
flights to and from RNO as set forth in the Agreement. Effective January 1, 2010, the base of operations of the above aircraft (the "RNO Aircraft") shall be changed to Laughlin/Bullhead City
International Airport, Bullhead City, Arizona ("IFP"), resulting in two IFP-based aircraft for the remaining portion of the Term of the Agreement. Charterer shall be free to continue
scheduling flights serving RNO subsequent to December 31, 2009, provided that such flights shall be subject to such away-from-base charges as are set forth in the
Agreement. 

        2.     Pursuant
to the Agreement, Charterer has guaranteed to Allegiant that effective January 1, 2010, Charterer shall make payment to Allegiant for at least
[...***...] Block Hours of use of the RNO Aircraft per calendar quarter, even if Actual Block Hours flown during the quarter are less than [...***...].
The change in the base of operations of the RNO Aircraft to IFP shall not relieve Charterer of its Minimum Block Hour Guarantee as to that or any other aircraft, subject to Paragraph 3 below. 

        3.     Pursuant
to the Agreement and this Amendment, Charterer has guaranteed to Allegiant that effective January 1, 2010, Charterer shall make payment to Allegiant for a
total of at least [...***...] Block Hours of use of the two IFP-based aircraft, collectively, per calendar quarter, even if Actual Block Hours flown during the
quarter are less than [...***...]. The parties agree that Actual Block Hours flown by these two aircraft, all of which shall be credited toward satisfaction of the quarterly
combined [...***...] guarantee, may occur in any combination that is operationally feasible. By way of illustration, [...***...] Actual Block Hours
flown on each IFP-based aircraft would satisfy the guarantee, as would [...***...] Actual Block Hours on one aircraft and [...***...] on the
other, as would any other operationally feasible combination totaling at least [...***...] hours. 

        4.     The
cost of repositioning the RNO Aircraft from its current base to IFP shall be borne by Charterer. 

 

Confidential treatment has been requested for portions of this document. This copy of the document filed as an Exhibit omits the confidential information subject to the
confidentiality request. Omissions are designated by the symbol [...***...]. A complete version of this document has been filed separately with the Securities and Exchange
Commission.

        5.     Pursuant
to the Agreement, Allegiant operates flights for Charterer serving Tunica, Mississippi (UTA) utilizing an MD-87 aircraft based at UTA (the "UTA
Aircraft"). In addition to, and not in replacement of, the service provided with the UTA Aircraft, Allegiant shall provide supplementary UTA service to Charterer throughout calendar year 2010
utilizing one or more of Allegiant's Florida-based 150-seat MD-83 aircraft or 130-seat MD-87 aircraft, as specified below (collectively, the "Florida
Aircraft"). All operations of the Florida Aircraft for Charterer will be governed by the provisions of the Agreement applicable to UTA service, subject to the following: 

        a.     Ordinarily,
an MD-83 aircraft shall be utilized as the Florida Aircraft. However, on the following dates during the first quarter of 2010, an
MD-87 aircraft shall be utilized unless Charterer's desired flight schedule for a given date permits use of an MD-83 on that date: February 1, 8 and 12; March 1,
5, 15, 17, 22, 24 and 26. Irrespective of whether an MD-83 or MD-87 is utilized, the Block Hour rate for the Florida Aircraft shall be the same as is applicable to the UTA
Aircraft for the respective date of operation. 

        b.     The
Florida Aircraft will be available to operate for Charterer on Mondays, Wednesdays and Fridays only, commencing on each date at 1:00 PM Eastern time at the aircraft's
Florida base of Orlando-Sanford (SFB), St. Petersburg/Clearwater (PIE) or Fort Lauderdale (FLL), which may vary depending on the specific aircraft assigned by Allegiant for operations on a
given date. 

        c.     One
the following dates in the month of April, the Florida Aircraft (MD-83) will not be available to Harrah's at 13:00 local time but will instead be
available at 14:30 local time: April 5, 7,19, 28, 30 

        d.     For
the first, second and third calendar quarters of 2010, Charterer hereby provides a Minimum Block Hour Guarantee of [...***...] hours per
quarter applicable to the Florida Aircraft, in the aggregate. For the fourth calendar quarter of 2010, Charterer hereby provides a Minimum Block Hour Guarantee of [...***...]
hours applicable to the Florida Aircraft, in the aggregate. 

        e.     For
the avoidance of doubt, Actual Block Hours operated by the Florida Aircraft shall include all ferry and live hours, including ferry flights to and from the aircraft's
base (SFB, PIE or FLL, as the case may be). 

        6.     Irrespective
of the number of Actual Block Hours flown on the Florida Aircraft, the Minimum Block Hour Guarantee applicable to the UTA Aircraft shall continue to apply as
set forth in the Agreement. 

        7.     Except
as set forth in this Amendment, the terms and conditions of the Agreement shall remain in full force and effect at all times; provided, that from and after
January 1, 2010, the provisions of Amendment No. 1 shall be of no further force or effect. Capitalized terms that appear in this Amendment and that are defined in the Agreement have the
same meaning in both documents.
