(b)Conversion of Aztar Common Stock. Subject to Section 2.02(e), each

issued and outstanding share of Aztar Common Stock (other than shares to be canceled in accordance with Section 2.01(a) and other than Aztar Dissenting Shares (as defined in Section 2.03(a)) shall be converted into the right to receive $38.00 per share in cash (the “Common Stock Merger Consideration”). As of the Effective Time, all such shares of Aztar Common Stock shall no longer be outstanding and shall automatically be canceled and retired and shall cease to exist, and each holder of a certificate representing any such shares of Aztar Common Stock shall cease to have any rights with respect thereto, except the right to receive the Common Stock Merger Consideration to be paid therefor upon the surrender of such certificate in accordance with Section 2.02, without interest.

(c)Conversion of Aztar Preferred Stock. Subject to Section 2.02(e), each issued and outstanding share of Aztar Preferred Stock (other than shares to be canceled in accordance with Section 2.01(a) and other than Aztar Dissenting Shares) shall be converted into the right to receive $401.90 per share in cash,provided that with respect to any share of Aztar Preferred Stock that has elected to receive the liquidation preference plus accrued and unpaid dividends in accordance with the certification of designations, preferences and rights of the Aztar Preferred Stock, each such share shall be converted into the liquidation preference thereof plus accrued and unpaid dividends as of the Effective Time (the “Preferred Stock Merger Consideration” and together with the Common Stock Merger Consideration, the “Merger Consideration”). The liquidation preference of a share of Aztar Preferred Stock is $100. As of the date hereof, the accrued and unpaid dividends thereon were less than $180,000 in the aggregate. As of the Effective Time, all such shares of Aztar Preferred Stock shall no longer be outstanding and shall automatically be canceled and retired and shall cease to exist, and each holder of a certificate representing any such shares of Aztar Preferred Stock shall cease to have any rights with respect thereto, except the right to receive the Preferred Stock Merger Consideration upon the surrender of such certificate in accordance with Section 2.02, without interest.

(d)Conversion of Merger Sub Common Stock. The aggregate of all shares of the capital stock of Merger Sub issued and outstanding immediately prior to the Effective Time (of which, as of the date of this Agreement, 1000 shares of common stock, par value $.01 per share, are issued and outstanding) shall be canceled.

Section 2.02Exchange of Certificates.

(a)Paying Agent. Prior to the Effective Time, Pinnacle shall enter into an agreement with such bank or trust company as may be mutually agreed by Pinnacle and Aztar (the “Paying Agent”), pursuant to which Pinnacle shall deposit with the Paying Agent at the Effective Time, for the benefit of the holders of shares of Aztar Common Stock and Aztar Preferred Stock, for exchange in accordance with this Article II, through the Paying Agent, cash representing the Common Stock Merger Consideration payable to holders of shares of Aztar Common Stock and cash representing the Preferred Stock Merger Consideration payable to holders of shares of Aztar Preferred Stock (the “Payment Fund”).

(b)Payment Procedures. As soon as reasonably practicable after the Effective Time, the Paying Agent shall mail to each holder of record of a certificate or certificates that

immediately prior to the Effective Time represented outstanding shares of Aztar Common Stock or Aztar Preferred Stock (the “Certificates”) whose shares were converted into the right to receive cash pursuant to Section 2.01, (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Paying Agent and shall be in such form and have such other provisions as Pinnacle may reasonably specify) and (ii) instructions for use in surrendering the Certificates in exchange for the applicable Merger Consideration. Upon surrender of a Certificate for cancellation to the Paying Agent, together with such letter of transmittal, duly executed, and such other documents as may reasonably be required by the Paying Agent, the holder of such Certificate shall be entitled to receive in exchange therefor, in the case of Certificates formerly representing shares of Aztar Common Stock, the Common Stock Merger Consideration, without interest, and in the case of Certificates formerly representing shares of Aztar Preferred Stock, the Preferred Stock Merger Consideration, without interest, in each case that such holder has the right to receive pursuant to the provisions of this Article II, and, in each case, the Certificate so surrendered shall forthwith be canceled. In the event of a transfer of ownership of Aztar Common Stock or Aztar Preferred Stock that is not registered in the transfer records of Aztar, the applicable Merger Consideration may be issued to a person other than the person in whose name the Certificate so surrendered is registered only if such Certificate shall be properly endorsed or otherwise be in proper form for transfer and the person requesting such issuance shall pay any transfer or other taxes required by reason of the payment of the applicable Merger Consideration to a person other than the registered holder of such Certificate or establish to the satisfaction of Pinnacle that such tax has been paid or is not applicable. Until surrendered as contemplated by this Section 2.02, each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the applicable Merger Consideration, which the holder thereof has the right to receive in respect of such Certificate pursuant to the provisions of this Article II. No interest shall be paid or will accrue on the Merger Consideration or any cash payable to holders of Certificates pursuant to the provisions of this Article II.

(c)No Further Ownership Rights in Aztar Capital Stock. All cash payments of Merger Consideration upon the surrender for exchange of Certificates in accordance with the terms of this Article II shall be deemed to have been paid in full satisfaction of all rights pertaining to the shares of Aztar Common Stock or Aztar Preferred Stock, as the case may be, theretofore represented by such Certificates, and there shall be no further registration of transfers on the stock transfer books of Aztar of the shares of Aztar Common Stock or Aztar Preferred Stock that were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to Pinnacle, Aztar or the Paying Agent for any reason, they shall be canceled and exchanged as provided in this Article II, except as otherwise provided by law.

(d)Termination of Payment Fund. Any portion of the Payment Fund that remains undistributed to the holders of the Certificates for six months after the Effective Time shall be delivered to Pinnacle, upon demand, and any holders of the Certificates who have not theretofore complied with this Article II shall thereafter look only to Pinnacle for payment of their claims for Merger Consideration.

(e)No Liability. None of Pinnacle, Aztar or the Paying Agent or any of their respective directors, officers, employees and agents shall be liable to any person in respect of any cash representing the Merger Consideration or any cash from the Payment Fund, in each case

delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. If any Certificate shall not have been surrendered prior to two years after the Effective Time (or immediately prior to such earlier date on which any Merger Consideration would otherwise escheat to or become the property of any Governmental Authority (as defined in Section 3.01(d)), any such Merger Consideration shall, to the extent permitted by applicable law, become the property of Pinnacle, free and clear of all claims or interest of any person previously entitled thereto.

(f)Investment of Payment Fund. The Paying Agent shall invest any cash included in the Payment Fund, as directed by Pinnacle, on a daily basis, in Permitted Investments (as defined in Section 8.03) or as otherwise consented to by Aztar prior to the Effective Time (which consent shall not be unreasonably withheld or delayed). Any interest and other income resulting from such investments shall be paid to Pinnacle.

(g)Withholding Rights. Pinnacle and the Paying Agent shall be entitled to deduct and withhold from any consideration payable pursuant to this Agreement to any person who was a holder of Aztar Common Stock or Aztar Preferred Stock, as the case may be, immediately prior to the Effective Time such amounts as Pinnacle and the Paying Agent may be required to deduct and withhold with respect to the making of such payment under the Internal Revenue Code of 1986, as amended (the “Code”) or any other provision of applicable federal, state, local or foreign tax law. To the extent that amounts are so withheld by Pinnacle or the Paying Agent and duly paid over to the applicable taxing authority, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the person to whom such consideration would otherwise have been paid.

(h)Lost, Stolen or Destroyed Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if required by Pinnacle, the posting by such person of a bond in such reasonable amount as Pinnacle may direct as indemnity against any claim that may be made against it with respect to such Certificate, the Paying Agent shall issue in exchange for such lost, stolen or destroyed Certificate, the applicable Merger Consideration pursuant to this Agreement.

(i)Adjustments to Prevent Dilution. In the event that Aztar changes the number of shares of Aztar Common Stock or securities convertible or exchangeable into or exercisable for shares of Aztar Common Stock, or shares of Aztar Preferred Stock or securities convertible or exchangeable into or exercisable for shares of Aztar Preferred Stock, issued and outstanding prior to the Effective Time, in each case as a result of a reclassification, stock split (including a reverse stock split), stock dividend or distribution, recapitalization, merger, subdivision, issuer tender or exchange offer, or other transaction, the applicable Merger Consideration shall be equitably adjusted.

Section 2.03Dissenting Shares. Any holder of shares of Aztar Common Stock or Aztar Preferred Stock who shall have exercised rights to dissent with respect to the Merger in accordance with the DGCL and who has properly exercised such holder’s rights to demand payment of the “fair value” of the holder’s shares of Aztar Common Stock or Aztar Preferred

Stock, as the case may be (the “Aztar Dissenting Shares”) as provided in the DGCL (the “Aztar Dissenting Stockholder”) shall thereafter have only such rights, if any, as are provided a dissenting stockholder in accordance with the DGCL and shall have no rights to receive the Merger Consideration pursuant to Section 2.01;provided,however, that if a Aztar Dissenting Stockholder shall fail to properly demand payment (in accordance with the DGCL) or shall have effectively withdrawn or lost such rights to relief as a Aztar Dissenting Stockholder under the DGCL, then such Aztar Dissenting Stockholder’s Aztar Dissenting Shares automatically shall cease to be Aztar Dissenting Shares and shall be converted into and represent only the right to receive, upon surrender of the Certificate representing the Aztar Dissenting Shares, the applicable Merger Consideration pursuant to Section 2.01, without interest.

Except as disclosed in Section 3.01(b)(v) of the Aztar Disclosure Letter, there are no (A) outstanding Options obligating Aztar or any of its subsidiaries to issue or sell any shares of capital stock of any subsidiary of Aztar or to grant, extend or enter into any such Option or (B) voting trusts, proxies or other commitments, understandings, restrictions or arrangements in favor of any person other than Aztar or a wholly owned subsidiary of Aztar with respect to the voting of or the right to participate in dividends or other earnings on any capital stock of any subsidiary of Aztar.

Aztar has full corporate power and authority to enter into this Agreement, to perform its obligations hereunder, and, subject to obtaining Stockholder Approval (as defined in Section 3.01(p)), to consummate the transactions contemplated hereby. The execution, delivery and performance of this Agreement by Aztar and the consummation by Aztar of the transactions contemplated hereby have been duly and validly adopted and approved by the Board of Directors of Aztar. No other corporate proceedings on the part of Aztar or its stockholders are necessary to authorize the execution, delivery and performance of this Agreement by Aztar and the consummation by Aztar of the Merger and the other transactions contemplated hereby, other than obtaining Stockholder Approval. This Agreement has been duly and validly executed and delivered by Aztar and constitutes a legal, valid and binding obligation of Aztar enforceable against Aztar in accordance with its terms. Aztar has received the opinion of Goldman, Sachs & Co., Inc., dated the date of this Agreement, to the effect that, as of the date of this Agreement, the Common Stock Merger Consideration is fair from a financial point of view to the holders of Aztar Common Stock.

Section 3.02Representations and Warranties of Pinnacle. Except as and to the extent set forth in the letter dated the date of this Agreement and delivered to Pinnacle by Aztar concurrently with the execution and delivery of this Agreement (the “Pinnacle Disclosure Letter”) and, to the extent the qualifying nature of such disclosure is readily apparent therefrom, except as and to the extent set forth in the Pinnacle Reports (as defined in Section 3.02(f)) filed on or after January 1, 2005 and prior to the date hereof (excluding any disclosures set forth in any risk factor section, in any section relating to forward looking statements and any other disclosures included therein to the extent that they are cautionary, predictive or forward-looking in nature), Pinnacle represents and warrants to Aztar as follows:

(a)Financing Commitments. Pinnacle has obtained written commitments (the “Financing Commitments”) for the financing necessary to consummate the Merger and the other transactions contemplated hereby (including any refinancing of indebtedness of Aztar or Pinnacle or any of their respective subsidiaries which Pinnacle deems it advisable to refinance in connection with the consummation of the Merger and the other transactions contemplated hereby) and to pay all associated fees, costs and expenses (the “Financing”). Pinnacle has provided true, accurate and complete copies of such commitments to Aztar. None of the Financing Commitments has been amended, modified or terminated prior to the date of this Agreement, and the respective commitments contained in the Financing Commitments have not been withdrawn or rescinded in any respect.

There are no conditions precedent or other contingencies related to the funding of the full amount of the Financing, other than as set forth in or contemplated by the Financing Commitments. The aggregate proceeds to be disbursed pursuant to the agreements contemplated by the Financing Commitments, together with Pinnacle’s and Aztar’s cash and cash equivalents, will be sufficient for Pinnacle to pay the aggregate Merger Consideration and to consummate the Consent/Tender Offers, if any (and any other repayment or refinancing of debt contemplated in this Agreement or the Financing Commitments), and to pay all related fees and expenses. Based on and assuming the accuracy of the representations and warranties of Aztar in this Agreement and the compliance by Aztar with its obligations hereunder, Pinnacle has no reason as of the date hereof to believe that any of the conditions to

the Financing contemplated by the Financing Commitments will not be satisfied or that the Financing will not be made available to Pinnacle on or prior the Closing Date. Nothing in this Agreement shall prevent Pinnacle from amending or modifying the Financing Commitments or from seeking to raise equity or other alternative sources of funds prior to the Closing, as long as such amendment or modification or other action does not prevent, delay or reduce the likelihood of the consummation of the Merger.

(b)Solvency. As of the Effective Time and after giving effect to all of the transactions contemplated by this Agreement, including the payment of the aggregate Merger Consideration, the Financing, consummation of the Consent/Tender Offers, if any (and any other repayment or refinancing of debt contemplated in this Agreement or the Financing Commitments), and payment of all related fees and expenses, and assuming the accuracy of the representations and warranties of Aztar in this Agreement and the compliance by Aztar with its obligations hereunder, the Surviving Corporation (on a combined basis with its subsidiaries) will be solvent (as defined in Section 8.03).

(c)Organization. Each of Pinnacle and its subsidiaries is duly organized, validly existing and in good standing under the laws of its jurisdiction of organization and has full power and authority to conduct its business as and to the extent now conducted and to own, use and lease its assets and properties, except for such failures to be so organized, existing and in good standing or to have such power and authority that, individually or in the aggregate, have not had and would not reasonably be expected to have a material adverse effect (as defined in Section 8.03) on Pinnacle. Each of Pinnacle and its subsidiaries is duly qualified, licensed or admitted to do business and is in good standing in each jurisdiction in which the ownership, use or leasing of its assets and properties, or the conduct or nature of its business, makes such qualification, licensing or admission necessary, except for such failures to be so qualified, licensed or admitted and in good standing that, individually or in the aggregate, have not had and would not reasonably be expected to have a material adverse effect on Pinnacle.

(d)Authority. Each of Pinnacle and Merger Sub has full corporate power and authority to enter into this Agreement, to perform its obligations hereunder and to consummate the transactions contemplated hereby. The execution, delivery and performance of this Agreement by Pinnacle and Merger Sub and the consummation by Pinnacle and Merger Sub of the transactions contemplated hereby have been duly and validly unanimously adopted and approved by the Board of Directors of Pinnacle and Merger Sub and by Pinnacle as the sole shareholder of Merger Sub. No other corporate proceedings on the part of Pinnacle, Merger Sub or their stockholders are necessary to authorize the execution, delivery and performance of this Agreement by Pinnacle or Merger Sub and the consummation by Pinnacle and Merger Sub of the Merger and the other transactions contemplated hereby. This Agreement has been duly and validly executed and delivered by Pinnacle and Merger Sub and constitutes a legal, valid and binding obligation of Pinnacle and Merger Sub enforceable against Pinnacle and Merger Sub in accordance with its terms.

Pinnacle shall indemnify Aztar and its directors and officers for any and all liabilities arising out of or in connection with any action taken pursuant to this Section 4.01(c) to the maximum extent permitted by Law.

(d) Nothing in Section 4.01(b) or 4.01(c) shall require Aztar and its subsidiaries to provide any assistance which would interfere unreasonably with the business or operations of Aztar and its subsidiaries. All reasonable out-of-pocket expenses incurred by Aztar or any of its subsidiaries, officers, employees, representatives and advisors in connection with their respective obligations pursuant to Section 4.01(b) and 4.01(c) shall be borne (or reimbursed promptly following demand therefor) by Pinnacle. Nothing in Section 4.01(b) or 4.01(c) shall require Aztar or any of its subsidiaries, officers, employees, representatives or advisors to take any action that might result in any liability in connection with the Financing unless indemnified by Pinnacle to the maximum extent permitted by Law or to take any action other than in their capacity as an officer. Pinnacle hereby agrees and acknowledges that Financing and the Consent/Tender Offers do not constitute conditions to the consummation of the transactions contemplated by this agreement.

Section 4.02Covenants of Pinnacle Interim Operations. Pinnacle will not take, and will not permit its subsidiaries to take, any action that at the time of taking such action is reasonably likely to prevent or materially delay the consummation of the Merger. Pinnacle agrees to use its reasonable best efforts to obtain the Financing necessary for the consummation of the transactions contemplated hereby at or prior to the Closing Date. Pinnacle shall use its reasonable best efforts to keep Aztar informed of the status of its efforts to obtain the Financing and of any development that Pinnacle believes is reasonably likely to prevent or delay the receipt of the Financing. Pinnacle shall use its reasonable best efforts to comply with the covenants in the Commitment Letter which are within its control.

Section 4.03No Solicitation by Aztar.

(a) Aztar shall not, nor shall it permit any of its subsidiaries to, nor shall it authorize or permit any of its directors, officers or employees, or any investment banker, financial advisor, attorney, accountant or other representative retained by it or any of its subsidiaries to, directly or indirectly, (i) solicit, initiate or knowingly encourage (including by way of furnishing non-public information), or knowingly take any other action designed to facilitate, any inquiries or the making of any proposal that constitutes a Takeover Proposal (as defined below) or (ii) participate in any negotiations or discussions (other than to state that they

are not permitted to have discussions) regarding any Takeover Proposal;provided,however, that if, at any time prior to receipt of the Stockholder Approval (the “Applicable Period”), the Board of Directors of Aztar determines in good faith, after consultation with its legal and financial advisors, that a Takeover Proposal that was not solicited by it after the date hereof and that did not otherwise result from a breach of this Section 4.03(a) is, or is reasonably likely to result in, a Superior Proposal (as defined in Section 4.03(b)), and subject to providing prior written notice of its decision to take such action to Pinnacle and compliance with Section 4.03(c), Aztar may (x) furnish information with respect to Aztar and its subsidiaries to the person making such proposal (and its representatives) pursuant to a customary confidentiality agreement (provided, that such confidentiality agreement shall not in any way restrict Aztar from complying with its disclosure obligations under this Agreement, including with respect to such proposal;provided further, that any such confidentiality agreement need not contain a standstill or similar provision) and (y) participate in discussions or negotiations regarding such proposal. Aztar agrees to provide Pinnacle with any information provided in writing or orally to the person making such Takeover Proposal and its representatives substantially simultaneously with the provision thereof to such other person. Aztar, its subsidiaries and their representatives immediately shall cease and cause to be terminated any activities, discussions or negotiations with any parties existing on the date hereof with respect to any Takeover Proposal. For purposes of this Agreement, “Takeover Proposal” means any bona fide inquiry, proposal or offer from any person relating to (i) any direct or indirect acquisition or purchase of a business (a “Material Business”) that constitutes 20% or more of the net revenues, net income or the assets (including equity securities) of Aztar and its subsidiaries, taken as a whole, (ii) any direct or indirect acquisition or purchase of 20% or more of any class of voting securities of Aztar or 20% or more of the voting power of any class of stock of any subsidiary of Aztar owning, operating or controlling a Material Business, (iii) any tender offer or exchange offer (or other offer to purchase or acquire) that if consummated would result in any person beneficially owning 20% or more of any class of voting securities of Aztar or 20% or more of the voting power of any class of stock of any subsidiary of Aztar owning, operating or controlling a Material Business, (iv) any merger, consolidation, business combination, recapitalization, liquidation, dissolution or similar transaction involving Aztar or any such subsidiary of Aztar owning, operating or controlling a Material Business or (v) any direct or indirect acquisition or purchase of, any joint venture or partnership or similar arrangement involving, or any recapitalization, restructuring or leveraged financing or similar transaction involving all or any portion of the Las Vegas Site (except as expressly specified in Section 4.01(a)(xii), in each case other than the transactions contemplated by this Agreement.

(b) Except as contemplated by this Section 4.03, neither the Board of Directors of Aztar nor any committee thereof shall (i) withdraw or modify, or propose publicly to withdraw or modify, in a manner adverse to Pinnacle, the approval or recommendation by such Board of Directors or such committee of this Agreement or the Merger, (ii) approve or recommend, or propose publicly to approve or recommend, any Takeover Proposal, or (iii) cause Aztar to enter into any letter of intent, agreement in principle, acquisition agreement or other similar agreement (other than a confidentiality agreement of the type and under the circumstances described in Section 4.03(a)) related to any Takeover Proposal (each, a “Aztar Acquisition Agreement”). Notwithstanding the foregoing, in response to a Takeover Proposal that was not solicited by it and that did not otherwise result from a breach of Section 4.03(a), during the Applicable Period, the Board of Directors of Aztar may, if it determines in good faith, after consulting with outside counsel, that taking such action is reasonably required by the Board

of Directors’ fiduciary obligations under applicable law, (A) withdraw or modify, or propose publicly to withdraw or modify, the approval or recommendation by such Board of Directors or any committee thereof of this Agreement or the Merger, (B) approve or recommend, or propose to approve or recommend, any Superior Proposal, or (C) terminate this Agreement pursuant to Section 7.01(d) simultaneously with the payment of the Termination Fee and the Termination Expenses, but only after (1) such Board of Directors has determined in good faith that such Takeover Proposal constitutes a Superior Proposal, and (2) (I) Aztar has notified Pinnacle in writing of the determination that such Takeover Proposal constitutes a Superior Proposal and (II) at least three business days following receipt by Pinnacle of such notice, the Board of Directors of Aztar has determined that such Superior Proposal remains a Superior Proposal. Notwithstanding the foregoing, other than in connection with a Takeover Proposal, the Board of Directors of Aztar may, if it determines in good faith, after consulting with outside counsel, that the failure to take such action would result in a breach of the Board of Directors’ fiduciary obligations under applicable Law withdraw or modify the approval or recommendation by such Board of Directors or any committee thereof of this Agreement or the Merger if Aztar has notified Pinnacle in writing of the decision to do so at least three business days prior to the taking of such action, which notice shall specify in writing the reasons therefor.

For purposes of this Agreement, “Superior Proposal” means any written Takeover Proposal that the Board of Directors of Aztar determines in good faith (after consultation with a financial advisor of nationally recognized reputation) to be more favorable (taking into account (i) all financial and strategic considerations, including relevant legal, financial, regulatory and other aspects of such Takeover Proposal and the Merger and the other transactions contemplated by this Agreement deemed relevant by the Board of Directors, (ii) the identity of the third party making such Takeover Proposal, (iii) the anticipated timing, conditions and prospects for completion of such Takeover Proposal, including the prospects for obtaining regulatory approvals and financing, and any third party shareholder approvals and (iv) the other terms and conditions of such Takeover Proposal) to Aztar’s stockholders than the Merger and the other transactions contemplated by this Agreement (taking into account all of the terms of any proposal by Pinnacle to amend or modify the terms of the Merger and the other transactions contemplated by this Agreement), except that (x) the reference to “20%” in clauses (i), (ii) and (iii) of the definition of “Takeover Proposal” in Section 4.03(a) shall be deemed to be a reference to “50%”, (y) the “Takeover Proposal” must refer to a transaction involving Aztar as a whole, and not any of its subsidiaries or Material Businesses or the Las Vegas Site, and (z) the references to any subsidiary of Aztar owning, operating or controlling a Material Business in clauses (ii), (iii) and (iv) shall be deemed to be deleted.

(c) In addition to the obligations of Aztar set forth in paragraphs (a) and (b) of this Section 4.03, Aztar shall as promptly as practicable advise Pinnacle, orally and in writing, of any request for information or of any Takeover Proposal (and in any case within 24 hours of such request or the receipt of such Takeover Proposal), the principal terms and conditions of such request or Takeover Proposal and the identity of the person making such request or Takeover Proposal. Aztar shall keep Pinnacle informed of the status and material details (including amendments or proposed amendments) of any such request or Takeover Proposal as promptly as practicable.

(d) Nothing contained in this Agreement shall prohibit Aztar from issuing a

“stop-look-and-listen communication” pursuant to Rule 14d-9(f), taking and disclosing to its stockholders a position as required by Rule 14d-9 or Rule 14e-2 promulgated under the Exchange Act or taking any action required by any order or decree of a Governmental Authority, in each case, subject to the provisions of Section 7.01(f).

Section 4.04Other Actions. Each of Aztar and Pinnacle shall use its reasonable best efforts not to, and shall use its reasonable best efforts not to permit any of their respective subsidiaries to, take any action that would, or that would reasonably be expected to, result in any condition to the Merger set forth in Article VI not being satisfied.

Section 4.05Control of Aztar’s Operations. Nothing contained in this Agreement shall give to Pinnacle, directly or indirectly, rights to control or direct Aztar’s operations prior to the Effective Time. Prior to the Effective Time, Aztar shall exercise, consistent with the terms and conditions of this Agreement, complete control and supervision of its operations.

(b) Aztar shall, as soon as reasonably practicable following the date of this Agreement, duly call, give notice of, convene and hold a meeting of its stockholders (the “Stockholders Meeting”) for the purpose of obtaining the Stockholder Approval.

Aztar shall be entitled to have representatives present at all times during any such inspection. Notwithstanding the foregoing, neither Aztar nor its subsidiaries shall be required to provide access to or to disclose any information (i) where such access or disclosure could jeopardize the attorney-client privilege or work product privilege of Aztar or its subsidiaries or contravene any Law or binding agreement entered into prior to the date of this Agreement, or (ii) to the extent that outside counsel to Aztar advises that such access or disclosure should not be disclosed in order to ensure compliance with any Gaming Law or other applicable Law. Pinnacle agrees to hold confidential all information which it has received or to which it has gained access pursuant to this Section 5.02(a) in accordance with the Confidentiality Agreement, dated as of March 11, 2006 between Aztar and Pinnacle (the “Confidentiality Agreement”).

(b)Effect of Review. No investigation or review pursuant to Section 5.02(a) shall have any effect for the purpose of determining the accuracy of any representation or warranty given by any of the parties hereto to any of the other parties hereto.

Section 5.03Regulatory Matters; Reasonable Best Efforts.

(a)Regulatory Approvals. Each party hereto shall cooperate and promptly prepare and file all necessary documentation, to effect all necessary applications, notices, petitions and filings, and shall use reasonable best efforts to take or cause to be taken all actions, and do or cause to be done all things in order to obtain all approvals and authorizations of all Governmental Authorities, necessary or advisable to consummate and make effective, in the most expeditious manner reasonably practicable, the Merger and the other transactions contemplated by this Agreement. Pinnacle shall have the responsibility for the preparation and filing of any required applications, filings or other materials, including in the State of New Jersey, a trust agreement necessary to obtain interim casino authorization;provided however that Aztar shall provide and cause its affiliates to provide Pinnacle with any information required in connection with such filings as promptly as practicable; and Aztar shall have the right to review and approve (which comments Aztar shall provide as promptly as practicable, but in any event within three days of Pinnacle’s request for such approval) in advance all characterizations of the information relating to Aztar that appear in any application, notice, petition or filing made in connection with the Merger or the other transactions contemplated by this Agreement. Aztar and Pinnacle agree that they will consult and cooperate with each other with respect to the obtaining of all such necessary approvals and authorizations of Governmental Authorities.

(b)Filings. Each of Pinnacle and Aztar undertakes and agrees to file as soon as practicable a Notification and Report Form under the HSR Act with the United States Federal Trade Commission (the “FTC”) and the Antitrust Division of the United States Department of Justice (the “Antitrust Division”) and to make such filings and apply for such approvals and consents as are required under the Gaming Laws as soon as practicable after the date hereof (and in any event within 45 days), including the filing of all required applications for Pinnacle and all “key persons” (as defined under applicable Gaming Laws). Each of Pinnacle and Aztar shall use its reasonable best efforts to request as soon as practicable an accelerated review (to the extent available) from any Gaming Authorities in connection with such filings and in the case of Gaming Approvals required in the State of New Jersey, Pinnacle shall seek to obtain interim casino authorization at the earliest practicable date. Each of Pinnacle and Aztar shall respond as promptly as practicable under the circumstances to any inquiries received from the FTC or the Antitrust Division or any authority enforcing applicable Gaming Laws for additional information or documentation and to all inquiries and requests received from any Governmental Authority in connection with any Law.

(c)Cooperation. In addition, each party shall, subject to applicable law and to the terms and conditions hereof, except as prohibited by any applicable representative of any applicable governmental entity, (i) promptly notify the other party of any material communication to that party relating to the Merger and the transactions contemplated hereby

Aztar will not, and will not permit any of its representatives to participate in any substantive meeting or discussion with any Governmental Authority in respect of any filings, investigation or inquiry concerning this Agreement or the Merger without the consent of Pinnacle, unless requested by such Governmental Authority and upon prior written notice by Aztar to Pinnacle of such request.

(d)Objections. In furtherance and not in limitation of the covenants of the parties contained in Section 5.03(a), (b) and (c), but subject to Section 5.03(g), each of Pinnacle and Aztar shall use its reasonable best efforts to resolve such objections, if any, as may be asserted by a Governmental Authority or other person with respect to the transactions contemplated hereby under any Antitrust Law or Gaming Law or by any Gaming Authority.

(e)Further Actions. Upon the terms and subject to the conditions set forth in this Agreement, each of the parties agrees to use its reasonable best efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with the other parties in doing, all things reasonably necessary or advisable under applicable Laws (including the HSR Act and the Gaming Laws) to consummate and make effective, in the most expeditious manner reasonably practicable, the Merger and the other transactions contemplated by this Agreement, including (i) obtaining any required third party consents and Governmental Consents and (ii) the execution and delivery of any additional instruments necessary to consummate the transactions contemplated by this Agreement.

(f)Governmental Consents. For purposes of this Agreement, the term “Governmental Consents” shall mean all notices, reports, filings, consents, applications, registrations, approvals, permits or authorizations required to be made prior to the Effective Time by Aztar or Pinnacle or any of their respective subsidiaries with, or obtained prior to the Effective Time by Aztar or Pinnacle or any of their respective subsidiaries from, any Governmental Authority in connection with the execution and delivery of this Agreement and the consummation of the Merger and the other transactions contemplated hereby (and shall include the expiration or termination of the waiting period under the HSR Act).

None of Aztar or any of its subsidiaries may take or agree to take any action, or consent to or agree to consent to any such restriction without the consent of Pinnacle. For purposes of clarification, Pinnacle agrees that if necessary in order to obtain the Required Governmental Consents (as defined in Section 6.01(c)), Pinnacle will (A) sell, or agree to sell, hold or agree to hold separate, or otherwise dispose, or agree to dispose of, the Specified Assets or (B) conduct or agree to conduct its business in a particular manner unless such conduct has had or would reasonably be expected to result in a Specified Material Adverse Effect.

(h)State Anti-Takeover Statutes. Without limiting the generality of Section 5.03(b), Aztar and Pinnacle shall (i) take all reasonable action necessary to ensure that no state anti-takeover statute or similar statute or regulation or charter, bylaw or similar provision becomes applicable to the Merger, this Agreement or any of the other transactions contemplated by this Agreement and (ii) if any state anti-takeover statute or similar statute or regulation, charter, bylaw or similar provision becomes applicable to the Merger, this Agreement or any other transaction contemplated by this Agreement, take all action necessary to ensure that the Merger and the other transactions contemplated by this Agreement may be consummated as promptly as reasonably practicable on the terms contemplated by this Agreement and otherwise to minimize the effect of such statute or regulation, charter, bylaw or similar provision on the Merger and the other transactions contemplated by this Agreement.

Section 5.04Stock Options; Stock Plans.

(a) Each stock option to purchase Aztar Common Stock (the “Aztar Employee Stock Options”) granted under the Aztar Employee Stock Plans that is outstanding as of or immediately prior to the Effective Time, shall be converted into the right to receive an amount in cash as soon as practicable following the Effective Time equal to the product of (x) the excess, if any, of the Common Stock Merger Consideration over the exercise price per Aztar Common Stock subject to such Aztar Employee Stock Option and (y) the total number of shares of Aztar Common Stock subject to such Aztar Employee Stock Option immediately before the Effective Time, with the aggregate amount of such payment rounded to the nearest cent, less such amounts as are required to be withheld or deducted under the Code or any provision of U.S. state, U.S. local or foreign Tax Law with respect to the making of such payment;

Section 5.05Employee Matters.

(a) Pinnacle agrees that, during the period commencing at the Effective Time and ending on the first anniversary of the Effective Time, the employees of Aztar and any of its subsidiaries who are employed as of the Closing Date and continue employment (the “Company Employees”) will continue to be provided with salary and benefits under employee benefit and commission or similar plans that are substantially similar, in the aggregate, to those currently provided by Aztar or any of its subsidiaries to such employees;provided that discretionary benefits shall remain discretionary.

(b) For purposes of all employee benefit plans, programs and agreements maintained by or contributed to by Pinnacle and its subsidiaries (including, after Closing, the Surviving Corporation), Pinnacle shall, or shall cause its subsidiaries to cause each such plan, program or arrangement to treat the prior service with Aztar or any of its subsidiaries immediately prior to the Closing of any Company Employee (to the same extent such service is recognized under analogous plans, programs or arrangements of Aztar or any of its subsidiaries prior to the Effective Time) as service rendered to Pinnacle or any of its subsidiaries, as the case may be, for all purposes;provided,however, that such crediting of service shall not (i) operate to duplicate any benefit or the funding of such benefit under any plan, (ii) require the crediting of past service for benefit accrual purposes under any defined benefit pension plan or (iii) be credited if past service credit has not been or will not be provided to employees of Pinnacle or its subsidiaries participating in such plan. Company Employees shall also be given credit for any deductible or co-payment amounts paid in respect of the plan year in which the Closing occurs, to the extent that, following the Closing, they participate in any other plan for which deductibles or co-payments are required. Pinnacle shall also cause each Pinnacle Plan (as defined below) to waive any preexisting condition or waiting period limitation which would otherwise be applicable to a Company Employee on or after the Effective Time (to the extent such limitation

would not apply under the corresponding Aztar Employee Benefit Plan). Pinnacle shall recognize any accrued but unused vacation of the Company Employees as of the Effective Time, and Pinnacle shall cause Aztar and its subsidiaries to provide such paid vacation. For purposes of this Agreement, a “Pinnacle Plan” shall mean such employee benefit plan, as defined in Section 3(3) of ERISA, or a nonqualified employee benefit or deferred compensation plan, stock option, bonus or incentive plan or other employee benefit or fringe benefit program, that may be in effect generally for employees of Pinnacle and its subsidiaries from time to time.

(f) Notwithstanding any provision of this Agreement to the contrary, Pinnacle shall not, for at least six months following the Closing cause there to be adopted any amendment to any Aztar Employee Benefit Plan that is a severance or retention plan, program, policy or agreement that would result in a diminution of benefits thereunder.

(a) Each of Aztar and Pinnacle agrees that, to the fullest extent permitted under applicable law, all rights to indemnification and exculpation from liabilities for acts or omissions occurring at or prior to the Effective Time now existing in favor of the current or former directors, officers, employees or fiduciaries under benefit plans currently indemnified of Aztar and its subsidiaries as provided in their respective certificate or articles of incorporation, by-laws (or comparable organizational documents) or other agreements providing indemnification shall survive the Merger and shall continue in full force and effect in accordance with their terms. The certificate of incorporation and by-laws of the Surviving Corporation shall continue to contain provisions no less favorable with respect to indemnification, advancement of expenses and exculpation of former or present directors and officers than are presently set forth in the Aztar’s certificate of incorporation and by-laws, which provisions shall not be amended, repealed or otherwise modified for a period of six years from the Effective Time in any manner that would adversely affect the rights thereunder of any such individuals.

(b) For six years after the Effective Time, the Surviving Corporation shall maintain in effect the directors’ and officers’ liability (and fiduciary) insurance policies covering acts or omissions occurring on or prior to the Effective Time with respect to those persons who

are currently covered by Aztar’s respective directors’ and officers’ liability (and fiduciary) insurance policies on terms with respect to such coverage and in amounts at least as favorable as those set forth in the relevant policy in effect on the date of this Agreement, except in no event shall the Surviving Corporation be required to make annual premium payments in connection therewith in excess of the amount set forth on Section 5.06(b) of the Aztar Disclosure Letter (the “Maximum Amount”), and if the Surviving Corporation is unable to obtain the insurance required by this Section 5.06(b), the Surviving Corporation shall maintain the most advantageous policies of directors’ and officers’ insurance otherwise obtainable for an annual premium equal to the Maximum Amount. Notwithstanding the foregoing, either Pinnacle or Aztar may elect in lieu of the foregoing insurance, prior to the Effective Time, to obtain and fully pay for a policy (providing only for the Side A coverage for the Aztar Indemnified Parties (as defined in clause (c) below) with a claims period of at least six years from the Effective Time from an insurance carrier with the same or better credit rating as Aztar’s current insurance carrier with respect to directors’ and officers’ liability insurance in an amount and scope the same as Aztar’s existing policies with respect to matters existing or occurring at or prior to the Effective Time; provided that the cost thereof does not exceed $4,435,000.

(c) From and after the Effective Time, Pinnacle agrees to cause the Surviving Corporation to indemnify and hold harmless each present or former director and officer of Aztar or any of its subsidiaries (in each case, for acts or failures to act in such capacity), determined as of the date hereof, and any person who becomes such a director or officer between the date hereof and the Effective Time (collectively, the “Aztar Indemnified Parties”), against any costs or expenses (including reasonable attorneys’ fees), judgments, fines, losses, claims, damages or liabilities (collectively, “Costs”) incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of matters existing or occurring at or prior to the Effective Time, whether asserted or claimed prior to, at or after the Effective Time (including any matters arising in connection with the transactions contemplated by this Agreement), to the fullest extent permitted by applicable law (and the Surviving Corporation shall also advance expenses as incurred to the fullest extent permitted under applicable law,provided that if required by applicable law the person to whom expenses are advanced provides an undertaking to repay such advances if it is ultimately determined that such person is not entitled to indemnification).

(d) The obligations of the Surviving Corporation under this Section 5.06 shall not be terminated or modified by such parties in a manner so as to adversely affect any Aztar Indemnified Party or any other person entitled to the benefit of Sections 5.06(a) and (b), as the case may be, to whom this Section 5.06 applies without the consent of the affected Aztar Indemnified Party or such other person, as the case may be. If the Surviving Corporation (i) shall consolidate with or merge into any other corporation or entity and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) shall transfer all or substantially all of its properties and assets to any individual, corporation or other entity, then, and in each such case, proper provisions shall be made so that the successors and assigns of the Surviving Corporation, as the case may be, shall assume all of the obligations set forth in Section 5.06.

Section 5.09Aztar Headquarters. For a period of not less than 9 months following the Effective Time, Pinnacle shall maintain the current headquarters of Aztar in Phoenix, Arizona as a divisional headquarters.

ARTICLE VII

Termination, Amendment and Waiver

Section 7.01Termination. This Agreement may be terminated at any time prior to the Effective Time, whether before or (other than pursuant to clauses (d) below) after the Stockholder Approval:

(b) by either Aztar or Pinnacle:

(i) if the Merger shall not have been consummated by the 12-month anniversary of the date of this Agreement (the “Termination Date”);provided,however, that the right to terminate this Agreement pursuant to this Section 7.01(b)(i) shall not be available to any party whose failure to perform any of its obligations under this Agreement results in the failure of the Merger to be consummated by such time;

(ii) if the Stockholder Approval shall not have been obtained at a Stockholders Meeting duly convened therefor or at any adjournment or postponement thereof;

(iii) if any Restraint having the permanent effects set forth in Section 6.01(b)(i) shall be in effect and shall have become final and nonappealable;provided that the party seeking to terminate this Agreement pursuant to this Section 7.01(b)(iii) shall have used its reasonable best efforts to prevent the entry of and to remove such Restraint; or

(iv) if any condition to the obligation of such party to consummate the Merger set forth in Section 6.02 (in the case of Aztar) or in Section 6.03 (in the case of Pinnacle) becomes incapable of satisfaction prior to the Termination Date;provided that the failure of any such condition to be capable of satisfaction is not the result of a material breach of this Agreement by the party seeking to terminate this Agreement;

(c) by Aztar, if Pinnacle shall have breached or failed to perform in any material respect any of its representations, warranties, covenants or other agreements contained in this Agreement, which breach or failure to perform (A) would give rise to the failure of a condition set forth in Section 6.02(a) or (b), and (B) is incapable of being cured by Pinnacle or is not cured by Pinnacle within 120 days following receipt of written notice from Aztar of such breach or failure to perform;

(d) by Aztar in accordance with Section 4.03(b);provided, that, in order for the termination of this Agreement pursuant to this paragraph (d) to be deemed effective, Aztar shall have complied with Section 4.03 and with applicable requirements, including the payment of the Termination Fee and Termination Expenses, of Section 5.07;

(e) by Pinnacle, if Aztar shall have breached or failed to perform in any material respect any of its representations, warranties, covenants or other agreements contained in this Agreement, which breach or failure to perform (A) would give rise to the failure of a condition set forth in Section 6.03(a) or (b), and (B) is incapable of being cured by Aztar or is not cured by Aztar within 120 days following receipt of written notice from Pinnacle of such breach or failure to perform;

(f) by Pinnacle, if the Board of Directors of Aztar (or any committee thereof) (i) shall have withdrawn or modified, or proposed publicly to withdraw or modify, the approval or recommendation by such Board of Directors of this Agreement or the Merger, or (ii) shall have approved or recommended, or proposed to approve or recommend, a Takeover Proposal (it being understood and agreed that any “stop-look-and-listen” communication by the Board of Directors of Aztar to the stockholders of Aztar limited to the matters specified in Rule 14d-9(f) of the Exchange Act, or any similar communication to the stockholders of Aztar in connection with the commencement of a tender offer or exchange offer limited to the “stop-look-and-listen” matters specified in Rule 14d-9(f), shall not be deemed to constitute an approval or recommendation of a Takeover Proposal); and

(g) by Pinnacle, in the event of a material breach of Section 4.03 or Section 5.01(b).

Section 7.02Effect of Termination. In the event of termination of this Agreement by either Pinnacle or Aztar as provided in Section 7.01, this Agreement shall forthwith become null and void and have no effect, without any liability or obligation on the part of Aztar or Pinnacle, other than the fee and indemnity provisions of Section 4.01(b), Section 4.01(c), and Section 4.01(d), and the confidentiality provisions of Section 5.02, Section 5.07, this Section 7.02 and Article VIII, which provisions shall survive such termination, and except to the

extent that such termination results from the willful and material breach by a party of any of its representations, warranties, covenants or agreements set forth in this Agreement, in which case such termination shall not relieve any party of any liability or damages resulting from its willful and material breach of this Agreement or in the case of Pinnacle, if all of the conditions to Pinnacle’s obligation to consummate the Merger are satisfied (other than the condition set forth in Section 6.03(c)) (and, in the case of the condition set forth in Section 6.03(c), either such condition has been satisfied or Aztar confirms to Pinnacle in writing that it is willing and able to deliver the certificate referred to in Section 6.03(c) as of the Closing Date) and Pinnacle fails to consummate the Merger in accordance with the terms and conditions hereof as a result of its failure to obtain the Financing.

Section 7.03Amendment. This Agreement may be amended by the parties at any time before or after the Stockholder Approval;provided,however, that after any such approval, there shall not be made any amendment that by law requires further approval by the stockholders of Aztar without the further approval of such stockholders.

Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” The words “hereof”, “herein” and “hereunder” and words of similar import when used in this Agreement shall refer to this Agreement as a whole and not to any particular provision of this Agreement. All terms defined in this Agreement shall have the defined meanings when used in any certificate or other document made or delivered pursuant hereto unless otherwise defined therein.

to which it relates. A matter set forth in one section of a disclosure letter need not be set forth in any other section of the disclosure letter so long as its relevance to the latter section of the disclosure letter or section of the Agreement is readily apparent on the face of the information disclosed in the disclosure letter to the person to which such disclosure is being made. The fact that any item of information is disclosed in a disclosure letter to this Agreement shall not be construed to mean that such information is required to be disclosed by this Agreement. Such information and the dollar thresholds set forth herein shall not be used as a basis for interpreting the terms “material,” “material adverse effect” or other similar terms in this Agreement.

Section 8.05Counterparts. This Agreement may be executed in one or more counterparts, all of which shall be considered one and the same agreement and shall become effective when one or more counterparts have been signed by each party and delivered to the other parties.

Section 8.06Entire Agreement; No Third-Party Beneficiaries. This Agreement (including the documents and instruments referred to herein) and the Confidentiality Agreement (i) constitute the entire agreement, and supersede all prior agreements and understandings, both written and oral, among the parties with respect to the subject matter of this Agreement and (ii) except for the provisions of Section 5.06 (which shall be enforceable by the Indemnified Parties), are not intended to and shall not confer upon any person other than the parties any rights or remedies.

Section 8.07Governing Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware, regardless of the laws that might otherwise govern under applicable principles of conflict of laws.

Section 8.08Assignment. Neither this Agreement nor any of the rights, interests or obligations under this Agreement shall be assigned, in whole or in part, by operation of law or otherwise by any of the parties hereto without the prior written consent of the other party.

Subject to the preceding two sentences, this Agreement shall be binding upon, inure to the benefit of, and be enforceable by, the parties and their respective successors and assigns.

Section 8.09Enforcement.

It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in any federal or state court located in the State of Delaware, this

being in addition to any other remedy to which they are entitled at law or in equity.

Section 8.10Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible to the fullest extent permitted by applicable law in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the extent possible.

Section 8.11WAIVER OF JURY TRIAL. EACH PARTY TO THIS AGREEMENT WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY ACTION, SUIT OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT.

Section 8.12Alternative Structure. The parties agree to cooperate in the consideration of alternative structures to implement the transactions contemplated by this Agreement as long as there is no change in the economic terms thereof and such change does not impose any material delay on, or condition to, the consummation of the Merger, or adversely affect Aztar, prior to the Effective Time, or Aztar’s stockholders or result in liability to Aztar’s directors or officers. Any such alternative structure shall constitute a “change of control” with respect to the Aztar Employee Benefit Plans and Aztar Employment Agreements to the same extent that the transactions contemplated hereby constitute a “change of control” with respect to the applicable Plan or Agreement.

IN WITNESS WHEREOF, Pinnacle, Aztar and Merger Sub have caused this Agreement to be signed by their respective officers thereunto duly authorized, all as of the date first written above.
