After the Closing Date and until the seventh (7th) anniversary thereof, each Party shall use its respective commercially reasonable efforts to provide, as promptly as possible, such assistance as the other Parties may from time to time reasonably request relating to the JV Companies and/or JV Assets, including access to the Books and Records in connection with the preparation of Tax Returns required to be filed, any audit or other examination by any taxing authority, any judicial or administrative proceeding relating to liability for Taxes, or any claim for refund in respect of such Taxes or in connection with any Third Party litigation and proceedings or liabilities related to the Offered Interests or the Assumed Liabilities; provided that nothing herein shall require the assisting Party to create, recreate, generate or obtain, in connection with rendering such assistance, any records, analyses or other documents not then in the possession or reasonable control of such assisting Party; provided, further, that notwithstanding anything to the contrary in this Section 6.3(c), no Party shall be obligated to disclose to the other Party data and information if such disclosure would disclose data and information (i) subject to legal privilege (including attorney-client), obligations owed to the other members of the JV Companies pursuant to any JV Governing Instruments or obligations of confidentiality owed to Third Parties or (ii) that would contravene any Laws or any JV Governing Instruments. The requesting Party shall reimburse the assisting Party for the reasonable out-of-pocket costs incurred by the assisting Party. Notwithstanding anything in the

35

foregoing to the contrary, in the event that any litigation (by Third party or Governmental Authority) or other administrative or judicial action or order is commenced, threatened or foreseeable challenging the transactions contemplated by this Purchase Agreement, each Party shall reasonably cooperate with the other and use their respective commercially reasonable efforts to respond to any such action or order.

6.3(d) Insurance Recovery. After the Closing Date and until the third (3^rd) anniversary thereof, with respect to any casualty or other loss or liability suffered within three (3) years prior to Closing by any JV Company that is reasonably expected to be successfully recovered from any Third Party insurance company whose coverage of such loss was not reinsured by an Affiliate captive insurer or similar reinsurance arrangement of Seller or its Affiliates, upon the written request of the Buyer delivered to any Seller from time to time during such three year period after Closing, such Seller shall (and shall cause its Affiliates, as applicable, to) reasonably cooperate with Buyer, at Buyer’s sole risk, to enable such Seller (for the account of Buyer) to attempt to collect any amounts available under such Third Party insurance coverage with respect to such loss or liability; provided, that Buyer shall be responsible for and shall pay for or reimburse each Seller (or its Affiliates, as applicable) for all costs and expenses incurred by such Seller (or its Affiliates, as applicable) in connection with such Seller’s or its Affiliates’ cooperation as described in this Section 6.3(d). If, after Closing, any Seller or any of its Affiliates, as applicable, receives any amounts with respect to the Offered Interests under applicable insurance policies related to the period prior to Closing, such Seller shall promptly pay such received amounts to Buyer, net of any costs and expenses incurred by such Seller (or its Affiliates, as applicable) in collecting such amounts. For the avoidance of doubt, the Sellers’ obligations under this Section 6.3(d) shall be in addition to the indemnification obligations of the Sellers under this Purchase Agreement; provided, that this last sentence of Section 6.3(d) shall not be deemed to alter any applicable reduction in indemnification obligations described in Section 11.2(e).

11.2(c) Indirect Losses.

(i) If any Losses for which any Seller has liability for indemnification hereunder are indirect Losses to Buyer, as a result of any Losses to or of the JV Companies arising from Buyer’s ownership of the Offered Interests, then such Seller’s liability for indemnification hereunder for such Losses shall not exceed the amount obtained by multiplying the monetary value of such Losses to or of such JV Company by a percentage equal to the aggregate ownership percentage in such JV Company represented by the respective Offered Interests acquired by Buyer at Closing pursuant to this Purchase Agreement (i.e., when determining the amount of any Losses suffered or incurred by the Buyer Group, Buyer’s acquisition of only (A) 25.0% of the membership interest of Phoenix LLC, (B) 22.6916% of the membership interests in URSA LLC, and (C) 45.0% of the membership interests in Mardi Gras (including the indirect acquisition of (1) 25.2% (45.0% of 56.0%) of the membership interest of Caesar LLC, (2) 23.85% (45.0% of 53.0%) of the membership interest of Cleopatra LLC, (3) 29.25% (45.0% of 65.0%) of the membership interest of Proteus LLC and (4) 29.25% (45.0% of 65.0%) of the membership interest of Endymion LLC), in each case, shall be taken into account, such that the aggregate Losses described in Article 11 suffered or incurred by the Buyer Group would equal (where applicable) no more than (a) 25.0% of the total of such Losses suffered or incurred by Phoenix LLC, (b) 22.6916% of the total of such Losses suffered or incurred by URSA LLC, and (c) 45.0% of the total of such Losses suffered or incurred by Mardi Gras (including (i) 25.2% (45.0% of 56.0%) of the total of such Losses suffered or incurred by Caesar LLC, (ii) 23.85% (45.0% of 53.0%) of the total of such Losses suffered or incurred by Cleopatra LLC, (iii) 29.25% (45.0% of 65.0%) of the total of such Losses suffered or incurred by Proteus LLC or (iv) 29.25% (45.0% of 65.0%) of the total of such Losses suffered or incurred by Endymion LLC), as the case may be).

(ii) If any Losses for which any Buyer has liability for indemnification hereunder are indirect Losses to any Seller, as a result of any Losses to or of the JV Companies arising from such Seller’s ownership of the applicable Offered Interests, then Buyer’s liability for indemnification hereunder for such Losses shall not exceed the amount obtained by multiplying the monetary value of such Losses to or of such JV Company by a percentage equal to the aggregate ownership percentage in such JV Company represented by the respective Offered Interests owned by such Seller immediately prior to Closing (i.e., when determining the amount of any Losses suffered or incurred by the Seller Group, Seller’s respective ownership of only (A) 25.0% of the membership interest of Phoenix LLC, (B) 22.6916% of the membership interests in URSA LLC, and (C) 45.0% of the membership interests in Mardi Gras (including the indirect acquisition of (1) 25.2% (45.0% of 56.0%) of the membership interest of Caesar LLC, (2) 23.85% (45.0% of 53.0%) of the membership interest of Cleopatra LLC, (3) 29.25% (45.0% of 65.0%) of the membership interest of Proteus LLC and (4) 29.25% (45.0% of 65.0%) of the membership interest of Endymion LLC), in each case, shall be taken into account, such that the aggregate Losses described in Article 11 suffered or incurred by the Seller Group would equal (where applicable) no more than (a) 25.0% of the total of such Losses suffered or incurred by Phoenix LLC, (b) 22.6916% of the total of such Losses suffered or incurred by URSA LLC, and (c) 45.0% of the total of such Losses suffered or incurred by

43

Mardi Gras (including (i) 25.2% (45.0% of 56.0%) of the total of such Losses suffered or incurred by Caesar LLC, (ii) 23.85% (45.0% of 53.0%) of the total of such Losses suffered or incurred by Cleopatra LLC, (iii) 29.25% (45.0% of 65.0%) of the total of such Losses suffered or incurred by Proteus LLC or (iv) 29.25% (45.0% of 65.0%) of the total of such Losses suffered or incurred by Endymion LLC), as the case may be).

11.2(d) Timeliness. Buyer shall not have any obligation to indemnify Sellers with respect to a matter if Sellers fail to deliver written notification of a claim for indemnification under Section 11.3(a) for such matter before the expiration of the applicable survival period set forth in Section 11.2(b), and Sellers shall not have any obligation to indemnify Buyer with respect to a matter if Buyer fails to deliver written notification of a claim for indemnification under Section 11.3(a) for such matter before the expiration of the applicable survival period set forth in Section 11.2(b).

11.2(e) Insurance Proceeds; Tax Benefits; Third-Party Indemnification Payments. Payments by either Buyer, on the one hand, to Sellers, or Seller(s), on the other hand, to Buyer, with respect to which such Party has an indemnification obligation under this Article 11, shall be limited to the amount of any liability or damage that remains after deducting therefrom an amount equal to (i) any insurance proceeds or other similar payments received, excluding any payments received directly or indirectly from Affiliate captive insurance companies, (ii) any Tax benefit actually realized by the Buyer in the Tax year that such payment is made as a result of such Losses by such Indemnified Party (as defined below), and (iii) all amounts recovered by such Indemnified Party under contractual indemnities from Third Parties. Each Party shall use its commercially reasonable efforts to recover under insurance policies or similar agreements, for any Losses prior to seeking indemnification under this Purchase Agreement. If the Indemnified Party receives insurance proceeds, excluding any payments received directly or indirectly from Affiliate captive insurance companies, or amounts recovered by such Indemnified Party under contractual indemnities from Third Parties for Losses after an indemnification payment for such Losses has been made by the Indemnifying Party to the Indemnified Party, the Indemnified Party will refund the Indemnifying Party both the amount of such insurance proceeds, excluding any payments received directly or indirectly from Affiliate captive insurance companies, and the amount recovered by such Indemnified Party under contractual indemnities from Third Parties received by the Indemnified Party.

11.3 Other Provisions Relating to Indemnification.

11.3(a) Notices, etc. Each Person entitled to indemnification pursuant to this Purchase Agreement (the “Indemnified Party”) agrees that within a reasonable period of time after it becomes aware of facts giving rise to a claim for indemnification under this Purchase Agreement, including receipt by it of notice of any demand, assertion, claim or proceeding by any Third Party (any such Third Party proceeding being referred to as a “Third Party Action”), it will provide notice thereof in writing to the Person obligated hereunder to provide such indemnification (the “Indemnifying Party”), specifying the nature of and specific basis for such claim. Notwithstanding anything to the contrary in the preceding sentence (and for the avoidance of doubt, assuming the Indemnified Party has complied with the timeliness obligations described in Section 11.2(d)), any failure so to notify the Indemnifying Party shall not relieve the Indemnifying Party from any liability that it may have to such Indemnified Party under this Article 11 unless and solely to the extent that the failure to give such notice actually prejudices the Indemnifying Party’s ability to defend such claim for indemnification under this Purchase Agreement.

44

11.3(b) Right to Contest and Defend. Subject to Section 11.3(e) below, the Indemnifying Party shall have the right to control all aspects of the defense of (and any counterclaims with respect to) any claims brought against the Indemnified Party that are covered by the indemnification obligations under this Purchase Agreement, including the selection of counsel, determination of whether to appeal any decision of any court and the settling of any such claim or any matter or any issues relating thereto; provided, however, that no such settlement for only the payment of money shall be entered into without the consent of the Indemnified Party, which consent shall not be unreasonably withheld, conditioned or delayed, unless it includes a full release of the Indemnified Party from such claim without admission of fault; provided further, that no such settlement containing any form of injunctive or similar relief shall be entered into without the prior written consent of the Indemnified Party, which consent shall not be unreasonably delayed or withheld.

11.3(c) Cooperation. Subject to Section 11.3(e) below, the Indemnified Party agrees to cooperate in good faith and in a commercially reasonable manner with the Indemnifying Party, with respect to all aspects of the defense of and pursuit of any counterclaims with respect to any claims covered by the indemnification obligations under this Purchase Agreement, including the prompt furnishing to the Indemnifying Party of any correspondence or other notice relating thereto that the Indemnified Party may receive, permitting the name of the Indemnified Party to be utilized in connection with such defense and counterclaims, the making available to the Indemnifying Party of any files, records or other information of the Indemnified Party that the Indemnifying Party considers relevant to such defense and counterclaims, the making available to the Indemnifying Party of any employees of the Indemnified Party and the granting to the Indemnifying Party of reasonable access rights to the properties and facilities of the Indemnified Party; provided, however, that in connection therewith the Indemnifying Party agrees to use reasonable efforts to minimize the impact thereof on the operations of the Indemnified Party and further agrees to maintain the confidentiality of all files, records, and other information furnished by the Indemnified Party pursuant to this Article 11. The obligation of the Indemnified Party to cooperate with the Indemnifying Party as set forth in the immediately preceding sentence shall not be construed as imposing upon the Indemnified Party an obligation to hire and pay for counsel in connection with the defense of and pursuit of any counterclaims with respect to any claims covered by the indemnification obligations set forth in this Purchase Agreement; provided, however, that the Indemnified Party may, at its own option, cost and expense, hire and pay for counsel in connection with any such defense and counterclaims. The Indemnifying Party agrees to keep any such counsel hired by the Indemnified Party informed as to the status of any such defense or counterclaim, but the Indemnifying Party shall have the right to retain sole control over such defense and counterclaims so long as the Indemnified Party is still seeking indemnification hereunder.

11.3(d) [Intentionally Omitted].

45

11.3(e) Exclusive Remedy. From and after the Effective Time, the indemnification provisions contained in this Article 11 shall constitute the sole remedy of the Parties against the other Parties for all claims arising from or relating to this Purchase Agreement or any of the instruments or transactions contemplated hereby (other than any remedies that are expressly set forth in any Operative Document), and each Party hereby releases the other Parties from all other claims and causes of action, whether arising in Contract, in tort (including claims and actions for fraud), or under any other legal theory arising from or relating to such circumstances. The Parties acknowledge and agree that the indemnification provisions contained in this Article 11 (including this Section 11.3(e)) have been specifically bargained for at arm’s length with the assistance of competent counsel and are reflected in the Purchase Price. For the avoidance of doubt, an Indemnifying Party shall have no obligation to provide indemnification pursuant to this Article 11 in the event the Indemnified Party’s written notification states only a general demand for indemnification which fails to identify a specific Loss or Third Party Action relating to such claim or demand.

11.3(f) No Duplication of Remedies. In no event shall either Buyer, on the one hand, or Sellers, on the other hand, be entitled to duplicate compensation with respect to any claims or any breach of representation, warranty or agreement herein asserted under the terms of this Purchase Agreement, even though such claim or breach may be addressed by more than one provision of this Purchase Agreement. For avoidance of doubt, no Losses may be claimed under this Article 11 by any Indemnifying Party to the extent such Losses are included in the calculation of any adjustment to the Purchase Price pursuant to Article 2. Any indemnification provided pursuant to this Purchase Agreement shall not be duplicative of any indemnification provided pursuant to the Omnibus Agreement.

11.3(g) Severability of Indemnification Provisions. If any indemnity obligation set forth in this Article 11 or the application of any part thereof is held invalid, illegal or unenforceable in any respect by a court of competent jurisdiction under Laws, then, but only in such event, such indemnity obligation or part thereof shall be modified, read, construed and enforced to the maximum extent permitted by Laws, and any remaining obligations or part thereof of such indemnity obligation that is valid and enforceable shall remain in full force and effect and be binding on the Parties.

11.3(h) Tax Treatment of Indemnity Payment. Parties agree to treat any indemnity payment made pursuant to this Article 11 as an adjustment to the Purchase Price, for all Tax purposes, unless otherwise required by applicable Law, a closing agreement with an applicable Tax authority or a final non-appealable judgment of a court of competent jurisdiction.

12.4 Failure to Close; Specific Performance. Each Party acknowledges and agrees that if the Closing fails to occur, or is rendered incapable of occurring, as a result of the breach by such Party of any term or provision of this Purchase Agreement (such breach, a “Closing Failure Breach”), the other Parties would be damaged irreparably and monetary damages may not be a sufficient remedy. Accordingly, each Party agrees that the other Parties shall be entitled to injunctive relief to prevent any such Closing Failure Breach and to enforce specifically this Purchase Agreement and the terms and provisions hereof in court, subject to Section 12.10; provided, that, for the avoidance of doubt, such remedies shall be in addition to any other remedies which any Party may have under this Purchase Agreement.

12.5 Waiver of Compliance. Any failure of Sellers, on the one hand, or Buyer, on the other hand, to comply with an obligation, covenant, agreement or condition contained in this Purchase Agreement may be expressly waived in writing by the non-failing Parties, but such waiver or failure to insist upon strict compliance shall not operate as a waiver of, or estoppel with respect to, any subsequent or other failure.

12.6 Notices. All notices, requests, demands and other communications required or permitted hereunder shall be in writing (provided, that, for the avoidance of doubt, transmissions by e-mail sent in accordance with this Section 12.6 shall be deemed to be in writing for purposes hereof) and shall be deemed to have been given (a) if delivered by hand (with written confirmation of receipt), (b) when received by the addressee if sent by courier service (with all fees prepaid and receipt requested), (c) on the third (3rd) day after the date mailed if mailed, by certified or registered mail (with postage prepaid and return receipt requested), or (d) on the date sent if transmitted by e-mail (with confirmation of transmission), or on the next Business Day if transmitted by e-mail after 5:00 p.m. CT on any such day (with confirmation of transmission):

In the event Buyer or any subsequent (direct or indirect) assignee of Buyer assigns this Purchase Agreement or any of its rights or interests under Article 11 of this Purchase Agreement to a Third Party pursuant to the terms hereof, Buyer or its subsequent assignee, as applicable, shall no longer have any rights to make a claim for indemnification under Article 11 following such assignment. Any purported assignment in violation of this Section 12.7 shall be voidable at the option of the non-assigning Party.

12.8 No Third Party Beneficiaries. Except as provided in Section 12.2 and Article 11, this Purchase Agreement is solely for the benefit of the Sellers and Buyer and their respective successors and assigns, and nothing in this Purchase Agreement shall confer any rights upon any other Person.

12.9 Governing Law. THIS PURCHASE AGREEMENT AND THE LEGAL RELATIONS AMONG THE PARTIES SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF DELAWARE, EXCLUDING ANY CHOICE OR CONFLICT OF LAW RULES WHICH MAY DIRECT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION; PROVIDED THAT THE VALIDITY AND ENFORCEABILITY OF ALL CONVEYANCE DOCUMENTS OR INSTRUMENTS EXECUTED AND DELIVERED PURSUANT TO THIS PURCHASE AGREEMENT INSOFAR AS THEY AFFECT TITLE TO REAL PROPERTY, IF THERE ARE ANY SUCH DOCUMENTS OR INSTRUMENTS, SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE JURISDICTION IN WHICH SUCH REAL PROPERTY IS LOCATED.

50

12.10 Consent to Jurisdiction. For any and all disputes, claims, counterclaims, demands, causes of action, controversies and other matters in question arising out of or relating to this Purchase Agreement, the transactions contemplated by this Purchase Agreement or any alleged breach hereof, including any disputes regarding a Party’s indemnification obligations pursuant to Article 11 or relating to matters that are the subject of this Purchase Agreement or the relationship among the Parties under this Purchase Agreement, regardless of whether (a) extra-contractual in nature, (b) sounding in contract, tort or otherwise, (c) provided for by Law or otherwise, or (d) any such matters could result in damages or any other relief, whether at Law, in equity or otherwise, each of the Sellers and Buyer (i) irrevocably submits to the exclusive jurisdiction of any state or federal court in Delaware, and (ii) irrevocably waives any objection that it may now or hereafter have to the laying of venue in such forums and agrees not to plead or claim that any action in such forums would be inconvenient. Except to the extent that a different determination or finding is mandated due to the Law being that of a different jurisdiction, the Parties agree that all judicial determinations or findings by a state or federal court in Wilmington, Delaware with respect to any matter under this Purchase Agreement shall be binding. EACH PARTY WAIVES IRREVOCABLY ANY AND ALL RIGHTS IT MAY HAVE TO TRIAL BY JURY.

12.11 Counterparts. This Purchase Agreement may be executed in one or more counterparts (including by means of a portable document format (*.pdf)), each of which shall be deemed an original but all of which together shall constitute one and the same instrument.

12.12 Exhibits and Headings. Information set forth in any Exhibit or Schedule to this Purchase Agreement is deemed to have been disclosed for all purposes of this Purchase Agreement. The headings contained in this Purchase Agreement are inserted for convenience only, do not constitute a part of this Purchase Agreement, and are in no way to be construed as a limitation on the scope of particular sections to which they refer.

12.13 Entire Agreement. Except for the Confidentiality Agreement, this Purchase Agreement (including the Exhibits, Schedules, and the Operative Documents, which form a part of this Purchase Agreement) embody the entire agreement and understanding of the Parties in respect of the subject matter contained herein and therein and supersede all prior and contemporaneous agreements and understandings among the Parties with respect to such subject matter. There are no, and none of the Parties shall have any remedies or causes of action (whether in contract or in tort, or under any other legal theory) for any, restrictions, promises, statements, warranties, covenants or undertakings with respect to the transactions contemplated hereby and thereby, other than those expressly set forth or referred to in this Purchase Agreement.

12.14 Representation By Counsel; No Strict Construction. Buyer and Sellers acknowledge and agree that (a) the Parties have participated jointly in the negotiation and drafting of this Purchase Agreement, (b) each of them has been represented by counsel in connection with the negotiation of this Purchase Agreement and the transactions contemplated

51

hereby and (c) the language used in this Purchase Agreement shall be deemed to be the language chosen by the Parties to express their mutual intent. In the event an ambiguity or question of intent or interpretation arises, this Purchase Agreement shall be construed as if drafted jointly by the Parties, no presumption or burden of proof shall arise favoring or disfavoring any Party by virtue of the authorship of any of the provisions of this Purchase Agreement. Any rule of Law or any legal decision that would require interpretation of any claimed ambiguities in this Purchase Agreement against the Party that drafted it shall have no application and is expressly waived.

12.15 Severability. Whenever possible, each provision or part thereof of this Purchase Agreement shall be interpreted in such manner as to be valid and effective under Laws, but if any provision or part thereof of this Purchase Agreement or the application of any such provision or part thereof to any Person or circumstance shall be held invalid, illegal, or unenforceable in any respect by a court of competent jurisdiction, all other provisions or parts thereof of this Purchase Agreement shall nevertheless remain in full force and effect, and such invalid, illegal or unenforceable provision or part thereof shall be reformed to the minimum extent required to render such provision or part valid, legal and enforceable and in a manner so as to preserve the economic and legal substance of the transactions contemplated by this Purchase Agreement to the fullest extent permitted by Laws.

12.16 Time of Essence. With regard to all rights and obligations of the Parties and all dates and time periods set forth or referred to in this Purchase Agreement, time is of the essence.

12.17 Press Releases and Public Announcements. The Parties shall not (and shall cause their Affiliates not to) issue any press release or make any public announcement relating to the subject matter of this Purchase Agreement unless such Party has first consulted with the other Parties and obtained the other Parties’ prior written approval of the text thereof, which approval shall not be unreasonably withheld or delayed; provided, however, that a Party may make any public disclosure it believes in good faith is required by Laws (including filings under securities Laws) or any listing or trading agreement concerning its publicly traded securities (in which case the disclosing Party will provide the other Parties reasonable advance notice and consultation regarding timing and content of the announcement or statement and with the further understanding that the Parties not required to make such announcement or statement shall have the right to issue its own announcement or statement in connection with or in response to any such required public announcement or statement).

12.18 Acknowledgement and Waiver of Post-Closing Attorney-Client Privilege. Each of the Parties acknowledges that one or more of Sellers and other members of the Seller Parties have retained Hunton Andrews Kurth LLP (“HAK”) to act as their counsel in connection with the transactions contemplated hereby and that HAK has not acted as counsel for any other Person in connection with the transactions contemplated hereby for conflict of interest or any other purposes. Buyer agrees that any attorney-client privilege and the expectation of client confidence attaching as a result of HAK’s representation of one or more of Sellers and other members of the Seller Parties related to the preparation for, and negotiation and consummation of, the transactions contemplated by this Purchase Agreement, including all communications among HAK and Sellers and other members of the Seller Parties or their respective Affiliates in preparation for, and negotiation and consummation of, the transactions contemplated by this Purchase Agreement (collectively “Deal Communications”), shall survive the Closing and shall

52

be deemed to be retained and owned collectively by such applicable Seller, shall be controlled by such applicable Seller and shall not pass to or be claimed by Buyer, Mardi Gras LLC or any of the JV Companies, without such Seller’s written consent. Buyer hereby releases any of its rights and interests to and in the Deal Communications, and none of Buyer, Mardi Gras or any of the JV Companies shall have access to any Deal Communications, unless approved by such Seller in its sole discretion. Buyer agrees that, notwithstanding any current or prior representation of Sellers by HAK, HAK shall be allowed to represent Sellers and any other member of the Seller Parties or any of their respective Affiliates in any matters and disputes adverse to Buyer that either is existing on the date hereof or arises in the future and relates to this Purchase Agreement and the transactions contemplated hereby, and Buyer hereby waives any conflicts or claim of privilege that may arise in connection with such representation. Further, Buyer agrees that, in the event that a dispute arises after Closing between Buyer and any Seller or its Affiliates, HAK may represent such Seller or its Affiliate in such dispute even though the interests of such Seller or its Affiliate may be directly adverse to Buyer.

12.19 Acknowledgement of Parties; Conspicuousness. EACH OF THE PARTIES SPECIFICALLY ACKNOWLEDGES AND AGREES (1) THAT IT HAS A DUTY TO READ THIS PURCHASE AGREEMENT AND THAT IT IS CHARGED WITH NOTICE AND KNOWLEDGE OF THE TERMS HEREOF, AND (2) THAT IT HAS IN FACT READ THIS PURCHASE AGREEMENT AND IS FULLY INFORMED AND HAS FULL NOTICE AND KNOWLEDGE OF THE TERMS, CONDITIONS AND EFFECTS OF THIS PURCHASE AGREEMENT.

12.20 Conflicts. In the event of any conflict between the provisions of this Purchase Agreement and the Operative Documents, the provisions of this Purchase Agreement shall control.
