Item 1.01.        Entry into a Material Definitive Agreement


                  On March 23, 2006, Aztar Corporation (the "Company") entered
into a severance agreement with Joe Cole, the Company's Vice President,
Corporate Communications, whose prior severance agreement expired in accordance
with its terms following his 65th birthday. The severance agreement has a term
ending on December 31, 2007, provided, that beginning on January 1, 2007 and
each January 1 thereafter, the term will be extended for one additional year
unless notice of non-extension is given not later than September 30 of the
preceding year, and provided, further, that the severance agreement will be in
effect for at least 24 months following a "change in control" (as defined in
the severance agreement). Upon a termination of Mr. Cole's employment occurring
during the term of the severance agreement and following a change in control,
either by the Company without "cause" (and other than due to Mr. Cole's death
or disability) or by Mr. Cole for "good reason" (each as defined in the
severance agreement), Mr. Cole would be entitled to the following severance
payments and benefits: (i) a cash payment equal to 200% of the greater of his
base salary in effect on the date of termination or his base salary in effect
on the date of the change in control, plus 200% of the average bonus paid to
Mr. Cole for the three fiscal years preceding the date of termination of
employment; (ii) full vesting of any then-outstanding restricted stock and
stock option awards; (iii) subject to the consent of the Company's compensation
committee, a cash payment in exchange for the cancellation of any
then-outstanding stock options that is equal to the excess, if any, of the
value of the Company's common stock on the day of payment (calculated generally
as the higher of the closing price of the Company's common stock on that date
or the highest per share price paid for the Company's common stock in
connection with the change in control) over the exercise price of the options;
(iv) 24 months' continued life, disability, accident and group health benefits
(subject to reduction if Mr. Cole obtains comparable benefits during the
24-month period); and (v) all legal fees and expenses incurred by Mr. Cole as a
result of the termination of his employment or in connection with any tax audit
or proceeding to the extent attributable to the "golden parachute" excise taxes
under Section 4999 of the Internal Revenue Code. Mr. Cole's benefits under the
severance agreement and any other Company plan or arrangement will be reduced
to the extent necessary to prevent any such payment or benefit from being
non-deductible due to application of the so-called "golden parachute" rules
under the Internal Revenue Code.

                  On March 23, 2006, the Company also entered into the
following material definitive agreements:

         (i)      Amendment No. 4 to the severance agreement between Aztar
                  Corporation and Nelson W. Armstrong, Jr., which has the
                  effect of extending the term of the severance agreement to
                  December 31, 2007; provided, that on January 1, 2007 and each
                  January 1 thereafter, the term of the severance agreement
                  will be extended one additional year unless notice of
                  non-extension is given not later than September 30 of the
                  preceding year; and provided, further, that upon a "change in
                  control" (as defined in the severance agreement), the term of
                  the severance agreement will be no less than 24 months
                  following the occurrence of a change in control;

         (ii)     Amendment to the Aztar Corporation Nonqualified Retirement
                  Plan for Senior Executives, which amendment clarifies the
                  Company's original intent with respect to the plan, which is
                  that following a "qualifying termination" of employment that
                  occurs following a "change in control" (each as defined in
                  the plan), participant benefits will be paid without
                  reduction for early commencement of benefits; and

         (iii)    Amendment No. 2 to the Aztar Corporation Nonqualified
                  Retirement Plan for Selected Senior Executives (SERP), which
                  amendment clarifies the Company's original intent with
                  respect to the plan, which is that following a "qualifying
                  termination" of employment that occurs following a "change in
                  control" (each as defined in the plan), participant benefits
                  will be paid without reduction for early commencement of
                  benefits and will be calculated as though the individual
                  continued employment until age 65.

                  The Company entered into a merger agreement with Pinnacle
Entertainment, Inc. and PNK Development 1, Inc. on March 13, 2006 (the "Merger
Agreement"). A copy of the Merger Agreement is filed as Exhibit 2.1 to the
Company's Current Report on Form 8-K, filed with the Securities and Exchange
Commission on March 14, 2006. If payments under the plans referenced in
paragraphs (ii) and (iii) above become payable as a result of the transactions
contemplated by the Merger Agreement, any additional benefits payable as a
result of the adoption of the amendments referenced in paragraphs (ii) and
(iii) above may not exceed $3 million in the aggregate.
