 Ladies and Gentlemen: 

PNK Finance Corp., a Delaware corporation (the “Issuer”) and newly formed, wholly-owned unrestricted
subsidiary of Pinnacle Entertainment, Inc., a Delaware corporation (the “Company”), proposes, upon the terms and conditions set forth in this agreement (this “Agreement), to issue and sell to the initial purchasers named
in Schedule 1 attached to this Agreement (the “Initial Purchasers”), for whom J.P. Morgan Securities LLC, Goldman, Sachs & Co., Deutsche Bank Securities Inc., Merrill Lynch, Pierce, Fenner & Smith
Incorporated, Wells Fargo Securities, LLC, Credit Agricole Securities (USA) Inc., Barclays Capital Inc. and UBS Securities LLC are acting as the representatives (“you” or the “Representatives”), an aggregate of
$850,000,000 principal amount of the Issuer’s 6.375% Senior Notes due 2021 (the “Notes”). 
 The Notes will be issued pursuant to an Indenture to be dated as of the Closing Date (as defined in Section 5(a)) (the “Indenture”), among the Issuer and The Bank of New York Mellon
Trust Company, N.A., as trustee (the “Trustee”). The Notes are more fully described in the Pricing Disclosure Package (as defined below) and the Offering Memorandum (as defined below). Immediately upon the consummation of
(i) the merger (the “Ameristar Merger”) of PNK Holdings, Inc., a Delaware corporation and wholly-owned subsidiary of the Company (“Holdco”), with and into Ameristar Casinos, Inc., a Nevada corporation

(“Ameristar”), pursuant to an Agreement and Plan of Merger, dated December 20, 2012, among the Company, Holdco, PNK Development 32, Inc., a Nevada corporation and
wholly-owned subsidiary of Holdco, and Ameristar (as amended or supplemented, the “Merger Agreement”), (ii) the merger (the “Post-Effective Merger”) of Ameristar with and into the Company immediately following
the consummation of the Ameristar Merger, and (iii) the merger (the “Issuer Merger” and, together with the Ameristar Merger and the Post-Effective Merger, the “Merger”) of the Issuer with and into the Company,
the Company and the Guarantors (as defined below) shall become party to the Indenture pursuant to a supplemental indenture (the “Supplemental Indenture”) by and among the Company, the Guarantors and the Trustee. 

Immediately upon consummation of the Merger, the Notes will be irrevocably and unconditionally guaranteed (the
“Guarantees”) on a senior unsecured basis, jointly and severally, by (i) the guarantors named in Schedule 2 hereto and (ii) any subsidiary of the Company or Ameristar formed or acquired after the Closing Date that
executes the Supplemental Indenture or an additional guarantee in accordance with the terms of the Indenture, and their respective successors and assigns (collectively, the “Guarantors”), in accordance with the terms of the
Indenture. The Company and the Guarantors shall immediately become subject to the terms of this Agreement upon execution by the Company and the Guarantors on the Merger Date (as defined herein) of a joinder agreement to this Agreement, the form of
which is attached hereto as Exhibit C (the “Joinder Agreement”). Upon execution of the Joinder Agreement, each of the Company and the Guarantors shall, without any further action by any person, become a party to this
Agreement, and the representations, warranties and agreements set forth herein shall become effective as to the Company and each Guarantor, giving effect to the consummation of the transactions contemplated by this Agreement, including the Merger,
as of the Applicable Time (as defined below). 
 On the Closing Date, the Issuer will enter into an escrow and
security agreement, the form of which is attached hereto as Exhibit D (the “Escrow Agreement”), with the Trustee and The Bank of New York Mellon Trust Company, N.A., in its capacity as escrow agent (the “Escrow
Agent”), pursuant to which, on the Closing Date, the Issuer will cause to be deposited with the Escrow Agent the gross proceeds of the offering of the Notes together with an additional amount in cash or Temporary Cash Investments (as
defined in the Escrow Agreement) sufficient to redeem the Notes at the Special Mandatory Redemption Price (as defined below) (together with any other property from time to time held by the Escrow Agent, the “Escrow Property”). The
Escrow Property will be held by the Escrow Agent in accordance with the terms and provisions set forth in the Escrow Agreement and released (the “Release”) to the Company in accordance with the conditions set forth therein. Until
the Escrow Property is so released, the Notes will be secured by a first-priority security interest in the Escrow Property. In the event that (a) the Merger Date does not take place on or prior to September 20, 2013 or such later date as
agreed by the parties to the Merger Agreement (such date, the “Outside Date”; provided that the Outside Date will not extend beyond December 31, 2013 under any circumstances) or (b) at any time prior to the Outside Date,
the Merger Agreement is terminated (any such event being a “Mandatory Redemption Event”), the Issuer will redeem (the “Special Mandatory Redemption”) all of the Notes at 100.00% of the issue price, plus accrued and
unpaid interest up to, and including, the Special Mandatory Redemption Date (the “Special Mandatory Redemption Price”). Notice of the occurrence of a Mandatory Redemption Event will be mailed by the Issuer (a “Special
Redemption Notice”) within three business days following the 

 
 3
 
  

 
occurrence of a Mandatory Redemption Event to the Trustee and the Escrow Agent. Concurrently with the delivery of the Special Redemption Notice, the Issuer shall request the Trustee to mail (by
first-class mail to each holder’s registered address or otherwise in accordance with the procedures of DTC (as defined below)) a notice that a Special Mandatory Redemption is to occur. Within five business days (or such other minimum period as
may be required by DTC) after the Trustee’s mailing of such notice of a Mandatory Redemption Event, the Special Mandatory Redemption shall occur (the date of such redemption, the “Special Mandatory Redemption Date”).

 This Agreement is to confirm the agreement concerning the purchase of the Notes from the Issuer by the
Initial Purchasers. 
 1.        Purchase and Resale of the
Notes.  The Notes will be offered and sold to the Initial Purchasers without registration under the Securities Act of 1933, as amended (the “Act”), in reliance on an exemption pursuant to Section 4(2) under
the Act. The Issuer, the Company and the Guarantors have prepared a preliminary offering memorandum, dated as of July 30, 2013 (the “Preliminary Offering Memorandum”), a pricing term sheet substantially in the form attached
hereto as Schedule 4 (the “Pricing Term Sheet”) and an offering memorandum, dated as of the date hereof (the “Offering Memorandum”), setting forth information regarding the Issuer, the Company, the
Guarantors, the Notes and the Exchange Notes (as defined herein), the Guarantees and the Exchange Guarantees (as defined herein). The Preliminary Offering Memorandum, as supplemented and amended as of the Applicable Time (as defined below), together
with the Pricing Term Sheet and any of the documents listed on Schedule 5 hereto, other than a road show that is a Free Writing Offering Document (as defined below), are collectively referred to as the “Pricing Disclosure
Package.” The Issuer hereby confirms that it has authorized the use of the Pricing Disclosure Package and the Offering Memorandum in connection with the offering and resale of the Notes by the Initial Purchasers. “Applicable
Time” means 3:05 p.m. (New York City time) on the date of this Agreement. 
 Any reference to the
Preliminary Offering Memorandum, the Pricing Disclosure Package or the Offering Memorandum shall be deemed to refer to and include all information filed by the Company and Ameristar with the United States Securities and Exchange Commission (the
“Commission”) pursuant to Section 13(a), 13(c), 14 or 15(d) of the United States Securities Exchange Act of 1934, as amended (the “Exchange Act”), on or prior to the date of the Preliminary Offering Memorandum,
the Pricing Disclosure Package or the Offering Memorandum, as the case may be, and incorporated by reference therein. Any reference to the Preliminary Offering Memorandum, the Pricing Disclosure Package or the Offering Memorandum, as the case may
be, as amended or supplemented, as of any specified date, shall be deemed to include any information filed by the Company and Ameristar with the Commission pursuant to Section 13(a), 13(c) or 15(d) of the Exchange Act after the date of the
Preliminary Offering Memorandum or the Offering Memorandum, as the case may be, and prior to such specified date, but only to the extent such information is deemed incorporated by reference therein. All documents filed under the Exchange Act and so
deemed to be included in the Preliminary Offering Memorandum, the Pricing Disclosure Package or the Offering Memorandum, as the case may be, or any amendment or supplement thereto are hereinafter called the “Exchange Act Reports.”

 It is understood and acknowledged that upon original issuance thereof,
and until such time as the same is no longer required under the applicable requirements of the Act, the Notes (and all securities issued in exchange therefor, in substitution thereof) shall bear the following legend (along with such other legends as
the Initial Purchasers and their counsel deem necessary): 
 ‘‘THE NOTES EVIDENCED
HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”). NEITHER THIS NOTE NOR ANY INTEREST OR PARTICIPATION HEREIN MAY BE REOFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE
DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION OR UNLESS THE TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. EACH PURCHASER OF THE SECURITY EVIDENCED HEREBY IS NOTIFIED THAT THE SELLER MAY BE
RELYING ON THE EXEMPTION FROM SECTION 5 OF THE SECURITIES ACT PROVIDED BY RULE 144A THEREUNDER. THE HOLDER OF THIS SECURITY BY ITS ACCEPTANCE HEREOF (1) REPRESENTS THAT (A) IT IS A “QUALIFIED INSTITUTIONAL BUYER” (AS DEFINED IN
RULE 144A UNDER THE SECURITIES ACT) OR (B) IT IS NOT A U.S. PERSON AND IS ACQUIRING ITS NOTE IN AN “OFFSHORE TRANSACTION” PURSUANT TO RULE 904 OF REGULATION S UNDER THE SECURITIES ACT, (2) AGREES THAT IT WILL NOT PRIOR TO
(X) THE DATE WHICH IS ONE YEAR (OR SUCH SHORTER PERIOD OF TIME AS PERMITTED BY RULE 144 UNDER THE SECURITIES ACT OR ANY SUCCESSOR PROVISION THEREUNDER) AFTER THE LATER OF THE ORIGINAL ISSUE DATE HEREOF (OR OF ANY PREDECESSOR OF THIS NOTE) OR
THE LAST DAY ON WHICH THE COMPANY OR ANY AFFILIATE OF THE COMPANY WAS THE OWNER OF THIS NOTE (OR ANY PREDECESSOR OF THIS NOTE) AND (Y) SUCH LATER DATE, IF ANY, AS MAY BE REQUIRED BY APPLICABLE LAW (THE “RESALE RESTRICTION TERMINATION
DATE”), OFFER, SELL OR OTHERWISE TRANSFER THIS NOTE EXCEPT (A) TO THE COMPANY, (B) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT, (C) FOR SO LONG AS THE NOTES ARE ELIGIBLE FOR
RESALE PURSUANT TO RULE 144A, TO A PERSON IT REASONABLY BELIEVES IS A “QUALIFIED INSTITUTIONAL BUYER” AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT THAT PURCHASES FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QUALIFIED INSTITUTIONAL BUYER
TO WHOM NOTICE IS GIVEN THAT THE TRANSFER IS BEING MADE IN RELIANCE ON RULE 144A, (D) PURSUANT TO OFFERS AND SALES TO NON-U.S. PERSONS THAT OCCUR OUTSIDE THE UNITED STATES WITHIN THE MEANING OF REGULATION S UNDER THE SECURITIES ACT OR
(E) PURSUANT TO ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION 

 
 5
 
  

 
REQUIREMENTS OF THE SECURITIES ACT AND (3) AGREES THAT IT WILL GIVE TO EACH PERSON TO WHOM THIS NOTE IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND; PROVIDED THAT THE
COMPANY, THE TRUSTEE AND THE REGISTRAR SHALL HAVE THE RIGHT PRIOR TO ANY SUCH OFFER, SALE OR TRANSFER PURSUANT TO CLAUSE (D) OR (E) TO REQUIRE THE DELIVERY OF AN OPINION OF COUNSEL, CERTIFICATION AND/ OR OTHER INFORMATION, ALL IN FORM AND
SUBSTANCE SATISFACTORY TO EACH OF THEM. THIS LEGEND WILL BE REMOVED UPON THE REQUEST OF THE HOLDER AFTER THE RESALE RESTRICTION TERMINATION DATE. AS USED HEREIN, THE TERMS “OFFSHORE TRANSACTION,” “UNITED STATES” AND “U.S.
PERSON” HAVE THE MEANINGS GIVEN TO THEM BY REGULATION S UNDER THE SECURITIES ACT.” 
 You have
advised the Issuer that the Initial Purchasers will make offers (the “Exempt Resales”) of the Notes purchased by the Initial Purchasers hereunder on the terms set forth in each of the Pricing Disclosure Package and the Offering
Memorandum, as amended or supplemented, solely to (i) persons whom the Initial Purchasers reasonably believe to be “qualified institutional buyers” as defined in Rule 144A under the Act (“QIBs”) and (ii) outside
the United States to certain persons who are not U.S. persons (as defined in Regulation S under the Act (“Regulation S”)) (such persons, “Non-U.S. Persons”) in offshore transactions in reliance on Regulation S.
Those persons specified in clauses (i) and (ii) are referred to herein as the (“Eligible Purchasers”). The Initial Purchasers will offer the Notes to Eligible Purchasers initially at a price equal to 100.00% of the
principal amount thereof. Such price may be changed at any time without notice. 
 Holders (including
subsequent transferees) of the Notes will have the registration rights set forth in the registration rights agreement (the “Registration Rights Agreement”) among the Issuer and the Initial Purchasers to be dated as of the Closing
Date (as defined in Section 5 herein), for so long as such Notes constitute “Transfer Restricted Securities” (as defined in the Registration Rights Agreement). Pursuant to the Registration Rights Agreement, the Issuer, the
Company and the Guarantors (following the execution by the Company and the Guarantors of a joinder agreement thereto upon the consummation of the Merger, such joinder agreement, the “Registration Rights Agreement Joinder”) will
agree to file with the Commission under the circumstances set forth therein, a registration statement under the Act (the “Exchange Offer Registration Statement”) relating to the Issuer’s 6.375% Senior Notes due 2021 (the
“Exchange Notes”) and the Guarantors’ Exchange Guarantees (the “Exchange Guarantees”) to be offered in exchange for the Notes and the Guarantees, which Guarantees are to be issued only upon the consummation of
the Merger, as described above. Such portion of the offering is referred to as the “Exchange Offer.” 
 2.        Representations, Warranties and Agreements of the Issuer, the Company and the Guarantors.  The Issuer and, upon execution of the
Joinder Agreement, the Company and each of the Guarantors, jointly and severally, represent, warrant and agree that (it being understood that, prior to the execution of the Joinder Agreement, all representations and

this Agreement, and when the Guarantees are issued upon the consummation of the Merger as described above, such Notes and Guarantees will not be of the same class (within the meaning of Rule 144A under the Act) as securities of the Issuer, the
Company or any of the Guarantors that are listed on a national securities exchange registered under Section 6 of the Exchange Act, or that are quoted in a United States automated inter-dealer quotation system. 

(b)        Assuming that (i) the representations and
warranties of the Initial Purchasers in Section 4 are true, (ii) the Initial Purchasers comply with their agreements and the offering and transfer procedures and restrictions described in Section 4, the Pricing Disclosure Package and
the Offering Memorandum, and (iii) each of the Eligible Purchasers is reasonably believed to be a QIB or is a Non-U.S. Person who acquires the Notes in an “offshore transaction” in reliance on Regulation S, the purchase and resale of
the Notes pursuant hereto (including pursuant to the Exempt Resales) is exempt from the registration requirements of the Act. No form of general solicitation or general advertising within the meaning of Regulation D (including, but not limited to,

general advertising) was used or will be used by the Issuer, the Company, the Guarantors any of their affiliates or any of their respective representatives (other than the Initial Purchasers, as to whom the Issuer, the Company and the Guarantors
make no representation) in connection with the offer and sale of the Notes. 

(c)        No form of general solicitation or general advertising
was used by the Issuer, the Company, the Guarantors or any of their respective representatives (other than the Initial Purchasers, as to whom the Issuer, the Company and the Guarantors make no representation) with respect to Notes sold outside the
United States to Non-U.S. Persons, by means of any directed selling efforts within the meaning of Rule 902 under the Act, and the Issuer, the Company, the Guarantors any affiliate of the Issuer, the Company, the Guarantors and any person acting on
its or their behalf (other than the Initial Purchasers, as to whom the Issuer, the Company and the Guarantors make no representation) has complied with and will implement the “offering restrictions” required by Rule 902. 

(d)        The Issuer is not required to deliver the information

(e)        The Pricing Disclosure Package and the Offering
Memorandum have been prepared by the Issuer, the Company and the Guarantors for use by the Initial Purchasers in connection with the Exempt Resales. No order or decree preventing the use of the Preliminary Offering Memorandum, the Pricing Disclosure
Package or the Offering

has commenced or is pending or, to the knowledge of the Issuer, the Company or any of the Guarantors, is contemplated. 
 (f)        The Pricing Disclosure Package did not, as of the Applicable Time, and will not, as of the Closing Date, contain any untrue statement of a material fact
or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided that no representation or warranty is made as to information contained
in or omitted from the Pricing Disclosure Package in reliance upon and in conformity with written information furnished to the Issuer through the Representatives by or on behalf of any Initial Purchaser specifically for inclusion therein, which
information is specified in Section 9(e). 

(g)        The Offering Memorandum will not, as of its date and
as of the Closing Date (as amended or supplemented in accordance with 6(d), as applicable), contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading, except that this representation and warranty does not apply to statements in or omissions from the Offering Memorandum made in reliance upon and in conformity with written information
furnished to the Issuer through the Representatives by or on behalf of the Initial Purchasers specifically for inclusion therein, which information is specified in Section 9(e). 

(h)        The Exchange Act Reports, when they were or are filed
with the Commission, conformed or will conform in all material respects to the applicable requirements of the Exchange Act and the applicable rules and regulations of the Commission thereunder. The Exchange Act Reports did not, and any further
documents filed and incorporated by reference in the Preliminary Offering Memorandum or the Offering Memorandum will not, when filed with the Commission, contain any untrue statement of a material fact or omit to state a material fact necessary in
order to make the statements therein, in the light of the circumstances under which they were made, not misleading. 
 (i)        Neither the Issuer, the Company nor any of the Guarantors (including their respective agents and representatives, other than the Initial Purchasers in
their capacity as such) has made any offer to sell or solicitation of an offer to buy the Notes that would constitute a “free writing prospectus” (if the offering of the Notes was made pursuant to a registered offering under the Act), as
defined in Rule 405 under the Act (a “Free Writing Offering Document”) without the prior consent of the Representatives; any such Free Writing Offering Document the use of which has been previously consented to by the Initial
Purchasers is listed on Schedule 5. 

(j)        Each Free Writing Offering Document (including,
without limitation, any electronic road show or other document listed on Schedule 5 hereto), when considered together with the Pricing Disclosure Package as of the Applicable Time, did not contain

 
 8
 
  

 
any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not
misleading. 
 (k)        The Issuer and each of the
Company, Ameristar and their respective subsidiaries (as defined in Section 17) listed on Schedule 3 to this Agreement and marked with an asterisk, including each of the Guarantors (collectively, the “Subsidiaries”), has
been duly organized, is validly existing and in good standing as a corporation or other business entity under the laws of its jurisdiction of organization and is duly qualified to do business and in good standing as a foreign corporation or other
business entity in each jurisdiction in which its ownership or lease of property or the conduct of its businesses requires such qualification, except where the failure to be so qualified or in good standing could not, individually or in the
aggregate, reasonably be expected to have a material adverse effect on (i) the business, condition (financial or otherwise), results of operations, stockholders’ equity, properties or prospects of the Company and its subsidiaries, taken as
a whole, or Ameristar and its subsidiaries, taken as a whole; (ii) the offering and sale of the Notes and Guarantees (the “Offering”) and the consummation of the Offering; or (iii) any other transaction contemplated by
this Agreement (including the Ameristar Merger, the Post-Effective Merger and the Issuer Merger) (a “Material Adverse Effect”). Except as disclosed in the Pricing Disclosure Package and the Offering Memorandum, each of the Company,

association or other entity other than the subsidiaries listed on Schedule 3 to this Agreement. None of the subsidiaries of the Company or Ameristar (other than the Subsidiaries) is a “significant subsidiary” (as defined in Rule
405). The Issuer does not have any subsidiaries. 

(l)        The Company has an authorized capitalization as set
forth in each of the Pricing Disclosure Package and the Offering Memorandum, and all of the issued shares of capital stock of the Issuer and the Company have been duly authorized and validly issued, are fully paid and non-assessable, conform to the
description thereof contained in each of the Pricing Disclosure Package and the Offering Memorandum and were issued in compliance with federal and state securities laws and not in violation of any preemptive right, resale right, right of first
refusal or similar right. All of the issued shares of capital stock or membership interests of each Subsidiary have been duly authorized and validly issued, (and with respect to capital stock are fully paid and non-assessable) and are owned directly
or indirectly by the Company or Ameristar, as the case may be, free and clear of all liens, encumbrances, equities or claims, except for such liens, encumbrances, equities or claims (i) created or arising in connection with the Company’s
Fourth Amended and Restated Credit Agreement dated as August 2, 2011, as it may be amended from time to time (the “Existing Bank Credit Facility”) or the Company’s anticipated new secured credit facility that will replace
the Existing Bank Credit Facility and Ameristar’s existing secured credit facility following the consummation of the Ameristar Merger (the “New Bank Credit Facility”) or (ii) as could not, in the aggregate, reasonably be
expected to have a Material Adverse Effect.

 23
 
  

 
“distribution compliance period”), other than in accordance with Regulation S or another exemption from the registration requirements of the Act. Each of the Initial Purchasers
further agrees that, during such 40-day distribution compliance period, it will not cause any advertisement with respect to the Notes (including any “tombstone” advertisement) to be published in any newspaper or periodical or posted in any
public place and will not issue any circular relating to the Notes, except such advertisements as permitted, and include the statements required, by Regulation S. Each of the Initial Purchasers also agrees that, at or prior to confirmation of a sale
of Notes offered and sold pursuant to Regulation S, it will have sent to each distributor, dealer or person receiving a selling concession, fee or other remuneration in respect of the Notes from it during the restricted period a confirmation or
notice substantially to the following effect: 
 “The Notes covered hereby have not been
registered under the U.S. Securities Act of 1933, as amended (the “Securities Act”), and may not be offered, sold, assigned, transferred, pledged, encumbered or otherwise transferred within the United States or to, or for the account or
benefit of, U.S. persons (i) as part of your distribution at any time or (ii) otherwise until 40 days after the later of the commencement of the Offering and the Closing Date, except in either case (A) in accordance with Regulation S
under the Securities Act, (B) to a “Qualified Institutional Buyer” (as defined in Rule 144A (“Rule 144A”) under the Securities Act) in a transaction meeting the requirements of Rule 144A or (C) to an institutional
“accredited investor” (as defined in Rule 501(a)(1), (2), (3), (5), (6) or (7) of Regulation D under the Securities Act) in a transaction that is exempt from the registration requirements of the Securities Act, and in connection
with any subsequent sale by you of the Notes covered hereby in reliance on Regulation S during the period referred to above to any distributor, dealer or person receiving a selling concession, fee or other remuneration, you must deliver a notice to
substantially the foregoing effect. Terms used above have the meanings assigned to them in Regulation S.” 

The Initial Purchasers have advised the Issuer that they will offer the Notes to Eligible Purchasers at a price
initially equal to 100.00% of the principal amount thereof, plus accrued interest, if any, from the date of issuance of the Notes. Such price may be changed by the Initial Purchasers at any time without notice. 

The Issuer shall not be obligated to deliver any Notes to be delivered on the Closing Date, except upon payment of the
aggregate principal amount (less the applicable discount and payment of interest set forth in Section 3 above) for all of the Notes to be purchased under this Agreement. 

Each of the Initial Purchasers understands that the Issuer, the Company and the Guarantors and, for purposes of the
opinions to be delivered to the Initial Purchasers pursuant to Section 8 hereof, counsel to the Issuer and the Company and counsel to the Initial Purchasers, 

 
 24
 
  

 
will rely upon the accuracy and truth of the foregoing representations, warranties and agreements and the Initial Purchasers hereby consent to such reliance. 

5.         Delivery of and Payment for the Notes. 

(a)       Delivery of and payment for the Notes shall be made at the
offices of Latham & Watkins LLP, 355 South Grand Avenue, Los Angeles, CA 90071, at 10:00 A.M., New York City time, on August 5, 2013 or at such other date or place as shall be determined by agreement between the Representatives and the

6.         Further Agreements of the Issuer, the Company, the
Guarantors and the Initial Purchasers.    Each of the Issuer and, upon execution of the Joinder Agreement, the Company and the Guarantors agrees as follows: 

(a)       The Issuer will furnish to the Initial Purchasers, without
charge, within one business day of the date of the Offering Memorandum, such number of copies of the Offering Memorandum as may then be amended or supplemented as they may reasonably request. 

(b)       None of the Issuer, the Company or any Guarantor will make
any amendment or supplement to the Pricing Disclosure Package or to the Offering Memorandum of which the Initial Purchasers shall not previously have been advised or to which they shall reasonably object after being so advised. 

(c)       The Issuer consents to the use of the Pricing Disclosure
Package and the Offering Memorandum, in accordance with the securities or Blue Sky laws of the jurisdictions in which the Notes are offered by the Initial Purchasers and by all dealers to whom Notes may be sold, in connection with the offering and
sale of the Notes. 
 (d)       If, at any time prior to
completion of the distribution of the Notes by the Initial Purchasers to Eligible Purchasers, any event occurs or information becomes known that, in the judgment of the Issuer or in the opinion of counsel for the Initial Purchasers, should be set
forth in the Pricing Disclosure Package or the Offering Memorandum so that the Pricing Disclosure Package or the Offering Memorandum, as then amended or supplemented, does not include any untrue statement of a material fact or omit to state any
material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it is necessary to supplement or amend the Pricing Disclosure Package or the Offering Memorandum in
order to comply with any law, the Issuer, the Company and the Guarantors will forthwith 

 
 25
 
  

 
prepare an appropriate supplement or amendment thereto, and will expeditiously furnish to the Initial Purchasers and dealers a reasonable number of copies thereof. 

(e)       Neither the Issuer, the Company nor any of the Guarantors
will make any offer to sell or solicitation of an offer to buy the Notes that would constitute a Free Writing Offering Document without the prior consent of the Representatives, which consent shall not be unreasonably withheld or delayed; if at any
time following issuance of a Free Writing Offering Document any event occurred or occurs as a result of which such Free Writing Offering Document conflicts with the information in the Pricing Disclosure Package or the Offering Memorandum or, when
taken together with the information in the Pricing Disclosure Package or the Offering Memorandum, includes an untrue statement of a material fact or omits to state any material fact necessary in order to make the statements therein, in the light of
the circumstances then prevailing, not misleading, as promptly as practicable after becoming aware thereof, the Issuer will give notice thereof to the Initial Purchasers through the Representatives and, if requested by the Representatives, will
prepare and furnish without charge to each Initial Purchaser a Free Writing Offering Document or other document which will correct such conflict, statement or omission. 

(f)       The Issuer, the Company and the Guarantors promptly from
time to time will take such action as the Representatives may reasonably request to qualify the Notes and Guarantees for offering and sale under the securities laws or Blue Sky laws of such jurisdictions as the Representatives may request and to
comply with such laws so as to permit the continuance of sales and dealings therein in such jurisdictions for as long as may be necessary to complete the distribution of the Notes; provided that in connection therewith, none of the Issuer,
the Company or any Guarantor shall be required to (i) qualify as a foreign corporation in any jurisdiction in which it would not otherwise be required to so qualify, (ii) file a general consent to service of process in any such
jurisdiction or (iii) subject itself to taxation in any jurisdiction in which it would not otherwise be subject. 
 (g)       During the period of 45 days from the date hereof, the Issuer, the Company and each of their respective subsidiaries (including, following the consummation of
the Merger, the former subsidiaries of Ameristar) will not, without the prior written consent of J.P. Morgan Securities LLC on behalf of the Initial Purchasers, which consent shall not be unreasonably withheld, directly or indirectly, issue, offer,
sell, agree to issue, offer or sell, solicit offers to purchase, pledge or otherwise dispose of (or enter into any transaction or duties which is designed to, or could be expected to, result in the disposition by any person at any time in the
future) any debt securities of the Company, Ameristar or any Subsidiary with terms substantially similar (including having equal rank) to the Notes (other than the Notes and other than the proposed redemption of the Company’s existing senior
notes due 2017 as described in the Offering Memorandum); provided, however, nothing contained in this Section 6(g) shall obligate the Company to retain J.P. Morgan Securities LLC as its initial purchaser or underwriter. 

(h)       The Company will furnish to the holders of the Notes as soon
as practicable after the end of each fiscal year an annual report (including a balance sheet 

 
 26
 
  

 
and statements of income, stockholders’ equity and cash flows of the Company and its consolidated subsidiaries certified by independent public accountants) and, as soon as practicable after
the end of each of the first three quarters of each fiscal year (beginning with the fiscal quarter ending after the date of the Offering Memorandum), will make available to its securityholders consolidated summary financial information of the
Company and its subsidiaries for such quarter in reasonable detail. 

(i)       So long as any of the Notes are outstanding, the Company and
the Guarantors will furnish to the Initial Purchasers (i) as soon as available, a copy of each report of the Company or any Guarantor mailed to stockholders generally or filed with any stock exchange or regulatory body and (ii) from time
to time such other information concerning the Company or the Guarantors as the Initial Purchasers may reasonably request. 
 (j)       The Issuer and the Company will apply the net proceeds from the sale of the Notes being sold by the Issuer as set forth in the Offering Memorandum under the
caption “Use of proceeds.” 
 (k)      The Issuer, the
Company and the Guarantors will not (and cause their respective affiliates not to) take, directly or indirectly, any action which is designed to or which constitutes or which might reasonably be expected to cause or result in the stabilization or
manipulation of the price of any security of the Issuer, the Company or any Guarantor to facilitate the sale or resale of the Notes and neither the Issuer, the Company, any of the Guarantors nor any of their affiliated purchasers (as defined in Rule
100 of Regulation M under the Exchange Act) will take any action prohibited by Regulation M under the Exchange Act. 
 (l)       The Issuer, the Company and the Guarantors will not oppose the Notes being made eligible for clearance and settlement through DTC. 

(m)     During the period from the Closing Date to one year after the Closing

by the Issuer, the Company, the Guarantors or any of their respective affiliates and resold in a transaction registered under the Act or pursuant to Rule 144 of the Act. 

(n)      The Issuer, the Company and the Guarantors agree not to sell,
offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in the Act) that would be integrated with the sale of the Notes in a manner that would require the registration under the Act of the sale to the
Initial Purchasers or the Eligible Purchasers of the Notes. 

(o)      The Issuer and, immediately following their execution of the
Registration Rights Joinder Agreement, the Company and each of the Guarantors agree to comply with all the terms and conditions of the Registration Rights Agreement and all 

 
 27
 
  

 
agreements set forth in the representation letters of the Issuer to DTC relating to the approval of the Notes by DTC for “book entry” transfer. 

(p)      The Issuer, the Company and the Guarantors will take such steps as
shall be necessary to ensure that neither the Issuer, the Company nor any of the Company’s subsidiaries (which, immediately following the Merger, shall include Ameristar and its subsidiaries) becomes an “investment company” within the
meaning of such term under the Investment Company Act of 1940, as amended. 

(q)      The Issuer agrees to use its best efforts to do and perform all
things required to be done or performed under this Agreement by it prior to the Closing Date to satisfy all conditions precedent to the delivery of the Notes.

Representatives shall have received from Ernst & Young LLP one (1) letter with respect to the Company and its subsidiaries and one (1) letter with respect to Ameristar and its subsidiaries, each in form and substance reasonably
satisfactory to the Representatives, addressed to the Initial Purchasers and dated the date hereof (i) confirming that Ernst & Young LLP is an independent registered public accounting firm within the meaning of the Act and the rules
and regulations of the PCAOB and are in compliance with the applicable requirements relating to the qualification of accountants under Rule 2-01 of Regulation S-X of the Commission, and (ii) stating,

the date hereof), such matters as set forth in drafts of such letters received on July 30, 2013 in substantially final form. 
 (r)        With respect to the letters of Ernst & Young LLP referred to in the preceding paragraph and delivered to the Representatives concurrently with
the execution of this Agreement (the “initial letters”), the Issuer shall have furnished to the Representatives letters (the “bring-down letters”), addressed to the Initial Purchasers and dated the Closing Date
(i) confirming that Ernst & Young LLP is an independent registered public accounting firm within the meaning of the Act and the rules and regulations of the PCAOB and are in compliance with the applicable requirements relating to the

reviews of the Company’s and Ameristar’s consolidated financial statements included in their respective Form 10-Qs for the quarter ended March 31, 2013 and filed with the Commission and other matters ordinarily covered by
accountants’ “comfort letters” to underwriters in connection with registered public offerings and (iii) confirming in all material respects the conclusions and findings set forth in the initial letters. 

(s)        The Issuer shall have furnished to the Representatives
a certificate, dated the Closing Date, of the Issuer’s President and its Chief Financial Officer stating, in their respective capacities as officers of the Issuer and not in their respective individual capacities, that each of them severally
represents that: 
 (i)        The representations, warranties and
agreements of the Issuer, the Company and the Guarantors (including, for the avoidance of doubt, Ameristar) in Section 2 are true and correct on and as of the Closing Date, and the Issuer, the Company and the Guarantors (including, for the
avoidance of doubt, Ameristar) have complied with all of their respective agreements contained herein 

 
 34
 
  

 
in all material respects and satisfied all the conditions on their part to be performed or satisfied hereunder at or prior to the Closing Date; 

(ii)       He or she has carefully examined the Pricing Disclosure Package and the
Offering Memorandum, and, in his or her opinion, (A) the Pricing Disclosure Package, as of the Applicable Time, and the Offering Memorandum, as of its date and the Closing Date, did not and do not contain any untrue statement of a material fact
and did not and do not omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, and (B) since the date of the Pricing Disclosure Package and
the Offering Memorandum no event has occurred that should have been set forth in a supplement or amendment to the Pricing Disclosure Package or the Offering Memorandum that has not been so set forth; and 

(iii)      Since the respective dates as of which information is given in the Pricing
Disclosure Package and the Offering Memorandum, there has not been any development that resulted in a Material Adverse Effect or any development that could reasonably be expected to result in a Material Adverse Effect, whether or not arising in the
ordinary course of business. 
 (t)        Except as
described in the Pricing Disclosure Package, none of the Company or any of its subsidiaries or, to the knowledge of the Issuer, Ameristar or any of its subsidiaries shall have sustained, since the date of the latest audited financial statements
included or incorporated by reference in the Pricing Disclosure Package, any change resulting in a Material Adverse Effect. 
 (u)       Subsequent to the execution and delivery of this Agreement (i) no downgrading shall have occurred in the rating accorded the Company’s or any of its
subsidiaries’ or Ameristar’s or any of its subsidiaries’ debt securities or preferred stock by Standard & Poor’s Corporation and Moody’s Investors Service and (ii) neither Standard & Poor’s
Corporation nor Moody’s Investors Service shall have publicly announced that it has under surveillance or review, with possible negative implications, its rating of any of the Company’s or any of its subsidiaries’ or Ameristar’s
or any of its subsidiaries’ debt securities or preferred stock. 

(v)       Subsequent to the execution and delivery of this Agreement
there shall not have occurred any of the following: (i) trading in securities generally on the New York Stock Exchange, or trading in any securities of the Company or Ameristar on any exchange or in the over-the-counter market, shall have been
suspended or materially limited or the settlement of such trading generally shall have been materially disrupted or minimum prices shall have been established on any such exchange or such market by the Commission, by such exchange or by any other
regulatory body or governmental authority having jurisdiction, (ii) a banking moratorium shall have been declared by federal or New York state authorities, (iii) the United States shall have become engaged in hostilities, there shall have
been an escalation in hostilities involving the United States or there shall have been a declaration of a national emergency or war by the United States 

 
 35
 
  

 
if the effect of such engagement in hostilities, escalation or declaration of national emergency or war would, in the reasonable judgment of J.P. Morgan Securities LLC, make it impracticable or
inadvisable to proceed with the offering, sale or delivery of the Notes or to enforce contracts for the sale of the Notes or (iv) there shall have occurred a material adverse change in financial markets or any calamity or crisis inside or
outside the United States or such a material adverse change in general economic, political or financial conditions, as to make it in each such case, in the reasonable judgment of J.P. Morgan Securities LLC, impracticable or inadvisable to proceed
with the offering, sale or delivery of the Notes or to enforce contracts for the sale of the Notes. 
 (w)      DTC shall have accepted the Notes for clearance.

Trustee shall have executed and delivered the Indenture, and the Initial Purchasers shall have received an original copy thereof, duly executed by the Issuer and the Trustee.

executed and delivered the Escrow Agreement and the Initial Purchasers shall have received an original copy thereof, duly executed by the Issuer, the Escrow Agent and the Trustee; the Escrow Property shall have been deposited into an account held by
the Escrow Agent in accordance with the Escrow Agreement; and the Issuer shall have duly executed all other necessary agreements, certificates, instruments and other documents and provided evidence that all other actions necessary or, in the
reasonable opinion of the Escrow Agent, desirable, to perfect the security interests of the Escrow Agent in the Escrow Property have been taken. 

(aa)     The Issuer shall have furnished the Representatives and counsel to the
Initial Purchasers with such other certificates, opinions or other documents as they may have reasonably requested. 
 All opinions, letters, evidence and certificates mentioned above or elsewhere in this Agreement shall be deemed to be in compliance with the provisions hereof only if they are in all material respects
reasonably satisfactory to counsel for the Initial Purchasers. 

9.        Indemnification and Contribution. 

(a)       The Issuer and, upon execution of the Joinder Agreement, the
Company and each of the Guarantors, jointly and severally, agree to indemnify and hold harmless each Initial Purchaser, its affiliates, directors, officers and employees and each person, if any, who controls any Initial Purchaser within the meaning
of Section 15 of the Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof (including, but not limited to, any loss, claim, damage, liability or action relating to purchases and sales of
Notes and Guarantees), to which that Initial Purchaser, affiliate, director, officer, employee or controlling person may become subject, under the Act or 

 
 36
 
  

 
otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained
(A) in any Free Writing Offering Document, the Preliminary Offering Memorandum, the Pricing Disclosure Package or the Offering Memorandum or in any amendment or supplement thereto, (B) in any Blue Sky application or other document prepared
or executed by the Issuer or, upon execution of the Joinder Agreement, the Company or any Guarantor (or based upon any written information furnished by the Issuer or, upon execution of the Joinder Agreement, the Company or any Guarantor)
specifically for the purpose of qualifying any or all of the Notes under the securities laws of any state or other jurisdiction (any such application, document or information being hereinafter called a “Blue Sky Application”) or
(C) in any materials or information provided to investors by, or with the approval of, the Issuer or the Company in connection with the marketing of the offering of the Notes (“Marketing Materials”), including any roadshow or
investor presentations made to investors by the Issuer or the Company (whether in person or electronically), (ii) the omission or alleged omission to state in any Free Writing Offering Document, the Preliminary Offering Memorandum, the Pricing
Disclosure Package or the Offering Memorandum or in any amendment or supplement thereto or in any Blue Sky Application or in any Marketing Materials, any material fact necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading or (iii) any act or failure to act or any alleged act or failure to act by any Initial Purchaser in connection with, or relating in any manner to, the Notes, the Guarantees or the
offering contemplated hereby, and which is included as part of or referred to in any loss, claim, damage, liability or action arising out of or based upon matters covered by clause (i) or (ii) above (provided that the Issuer, the
Company and the Guarantors shall not be liable under this clause (iii) to the extent that it is determined in a final judgment by a court of competent jurisdiction that such loss, claim, damage, liability or action resulted directly from any
such acts or failures to act undertaken or omitted to be taken by such Initial Purchaser through its gross negligence, bad faith or willful misconduct), and shall reimburse each Initial Purchaser and each such director, officer, employee or
controlling person promptly upon demand for any legal or other out-of-pocket expenses reasonably incurred by that Initial Purchaser, director, officer, employee or controlling person in connection with investigating or defending or preparing to
defend against any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Issuer, the Company and the Guarantors shall not be liable in any such case to the extent that any such loss,
claim, damage, liability or action arises out of, or is based upon, any untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Offering Memorandum, the Pricing Disclosure Package or the Offering
Memorandum or in any such amendment or supplement thereto or in any Blue Sky Application or any Marketing Materials, in reliance upon and in conformity with written information furnished to the Issuer through the Representatives by or on behalf of
any Initial Purchaser specifically for inclusion therein, which information consists solely of the information specified in Section 9(e). The foregoing indemnity agreement is in addition to any liability which the Issuer, the Company or the
Guarantors may otherwise have to any Initial Purchaser or to any affiliate, director, officer, employee or controlling person of that Initial Purchaser. 

 
 37
 
  

 (b)        Each
Initial Purchaser, severally and not jointly, shall indemnify and hold harmless the Issuer and, upon execution of the Joinder Agreement, the Company and each of the Guarantors and their respective directors, officers and employees, and each person,
if any, who controls the Issuer or, upon execution of the Joinder Agreement, the Company or the Guarantors, as the case may be, within the meaning of Section 15 of the Act, from and against any loss, claim, damage or liability, joint or
several, or any action in respect thereof, to which the Issuer, the Company (upon execution of the Joinder Agreement), the Guarantors (upon execution of the Joinder Agreement) or any such director, officer, employee or controlling person may become
subject, under the Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in any Free Writing Offering
Document, Preliminary Offering Memorandum, the Pricing Disclosure Package or the Offering Memorandum or in any amendment or supplement thereto or in any Blue Sky Application or any Marketing Materials, or (ii) the omission or alleged omission
to state in any Free Writing Offering Document, Preliminary Offering Memorandum, the Pricing Disclosure Package or the Offering Memorandum or in any amendment or supplement thereto or in any Blue Sky Application or any Marketing Materials, any
material fact necessary to make the statements therein not misleading, but in each case only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written
information furnished to the Issuer through the Representatives by or on behalf of that Initial Purchaser specifically for inclusion therein, which information is limited to the information set forth in Section 9(e). The foregoing indemnity
agreement is in addition to any liability that any Initial Purchaser may otherwise have to the Issuer, the Company, any Guarantor and any such director, officer, employee or controlling person. 

(c)        Promptly after receipt by an indemnified party under
this Section 9 of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 9, notify the indemnifying party in writing
of the claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under this Section 9 except to the extent the party to
whom notice was not given was unaware of the proceeding to which such notice would have related and has been materially prejudiced by such failure (through the forfeiture of substantive rights or defenses or a material diminution thereof) and,
provided, further, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this Section 9. If any such claim or action shall be
brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying
party, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party and shall pay as incurred the reasonable fees and disbursements of such counsel related to such proceeding. After notice from the indemnifying party
to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 9 for any legal or other expenses subsequently incurred by the
indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, 

 
 38
 
  

 
that an indemnified party shall have the right to employ counsel to represent jointly the indemnified parties and their respective directors, officers, employees and controlling persons who may
be subject to liability arising out of any claim in respect of which indemnity may be sought by the indemnified parties against the indemnifying party under this Section 9 if (i) the indemnified party and the indemnifying party shall have
so mutually agreed; (ii) the indemnifying party has failed within a reasonable time to retain counsel reasonably satisfactory to the indemnified party; (iii) counsel for the indemnified parties and their respective directors, officers,
employees and controlling persons determines in good faith that there may be legal defenses available to them that are different from or in addition to those available to the indemnifying party; or (iv) the named parties in any such proceeding
(including any impleaded parties) include both the indemnifying parties or their respective directors, officers, employees or controlling persons, on the one hand, and the indemnified party on the other hand, and representation of both sets of
parties by the same counsel, as determined by counsel for the indemnified parties in good faith, would be inappropriate due to actual or potential differing interests between them, and in any such event, the fees and expenses of such separate
counsel shall be paid by the Issuer and, upon execution of the Joinder Agreement, the Company and the Guarantors (it being understood however that the Issuer and, upon execution of the Joinder Agreement, the Company and the Guarantors will not be
liable for the expense of more than one primary counsel and, if necessary, one local counsel in each appropriate jurisdiction to represent such indemnified parties and all other indemnified parties similarly situated). Any such separate firm for any
Initial Purchaser, its affiliates, directors, officers, employees and any control persons of such Initial Purchaser shall be designated in writing by J.P. Morgan Securities LLC and any such separate firm for the Issuer, the Company (upon execution
of the Joinder Agreement), the Guarantors (upon execution of the Joinder Agreement), their respective directors and officers, employees and any control persons of the Issuer and, upon execution of the Joinder Agreement, the Company and the
Guarantors shall be designated in writing by the Company. No indemnifying party shall (A) without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld), settle or compromise or consent to the
entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to
such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and does not include any findings of fact or
admissions of fault or culpability as to the indemnified party, or (B) be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with the consent of
the indemnifying party or if there be a final judgment for the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or
judgment. In the event that it is finally judicially determined that any indemnified party was not entitled to receive payments for legal and other expenses pursuant to this Section 9, the indemnified party will promptly return all sums that
that had been advanced pursuant hereto. 

 
 39
 
  

 (d)        If
the indemnification provided for in this Section 9 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party under Section 9(a) or 9(b) in respect of any loss, claim, damage or liability, or any action in
respect thereof, referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or
action in respect thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Issuer, and, upon execution of the Joinder Agreement, the Company and the Guarantors, on the one hand, and the Initial
Purchasers, on the other, from the offering of the Notes and Guarantees or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative
benefits referred to in clause (i) above but also the relative fault of the Issuer and, upon execution of the Joinder Agreement, the Company and the Guarantors, on the one hand, and the Initial Purchasers, on the other, with respect to the
statements or omissions that resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by the Issuer and, upon execution of the Joinder
Agreement, the Company and the Guarantors, on the one hand, and the Initial Purchasers, on the other, with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from the offering of the Notes purchased under
this Agreement (net of Initial Purchasers’ discounts and commissions but before deducting other expenses) received by the Issuer, on the one hand, and the total discounts and commissions received by the Initial Purchasers with respect to the
Notes purchased under this Agreement, on the other hand. The relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to
information supplied by the Issuer, the Company (upon execution of the Joinder Agreement), the Guarantors (upon execution of the Joinder Agreement) or the Initial Purchasers, the intent of the parties and their relative knowledge, access to
information and opportunity to correct or prevent such statement or omission. For purposes of the preceding two sentences, the net proceeds deemed to be received by the Issuer shall be deemed, upon execution of the Joinder Agreement, to be also for
the benefit of the Company and the Guarantors, and information supplied by the Issuer shall also be deemed to have been supplied, upon execution of the Joinder Agreement, by the Company and the Guarantors. The Issuer, the Company (upon execution of
the Joinder Agreement), the Guarantors (upon execution of the Joinder Agreement) and the Initial Purchasers agree that it would not be just and equitable if contributions pursuant to this Section 9(d) were to be determined by pro rata
allocation (even if the Initial Purchasers were treated as one entity for such purpose) or by any other method of allocation that does not take into account the equitable considerations referred to herein. The amount paid or payable by an
indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 9(d) shall be deemed to include, for purposes of this Section 9(d), any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 9(d), no Initial Purchaser shall be required to contribute any amount in excess
of the amount by which the total discounts and commissions received by such Initial Purchaser with respect to the offering of the Notes 

 
 40
 
  

 
exceeds the amount of any damages that such Initial Purchaser has otherwise paid or become liable to pay by reason of any untrue or alleged untrue statement or omission or alleged omission. No
person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Initial Purchasers’ obligations
to contribute as provided in this Section 9(d) are several in proportion to their respective purchase obligations and not joint. 
 (e)        The Initial Purchasers severally confirm and the Issuer and, upon execution of the Joinder Agreement, the Company and the Guarantors acknowledge and
agree that the statements regarding delivery of Notes by the Initial Purchasers set forth on the cover page of, and the seventeenth paragraph, relating to overallotment, stabilization and syndication transactions by the Initial Purchasers, appearing
under the caption “Plan of Distribution” in, the Offering Memorandum are correct and constitute the only information concerning such Initial Purchasers furnished in writing to the Issuer by or on behalf of the Initial Purchasers
specifically for inclusion in the Preliminary Offering Memorandum, the Pricing Disclosure Package and the Offering Memorandum or in any amendment or supplement thereto. 

10.        Defaulting Initial
Purchaser.      If, on the Closing Date, any Initial Purchaser defaults in the performance of its obligations under this Agreement, the remaining non-defaulting Initial Purchasers shall be obligated to purchase
the Notes that the defaulting Initial Purchaser agreed but failed to purchase on the Closing Date in the respective proportions which the principal amount of the Notes set forth opposite the name of each remaining non-defaulting Initial Purchaser in
Schedule 1 hereto bears to the total principal amount of the Notes set forth opposite the names of all the remaining non-defaulting Initial Purchasers in Schedule 1 hereto; provided, however, that the remaining non-defaulting
Initial Purchasers shall not be obligated to purchase any of the Notes on the Closing Date if the total principal amount of the Notes that the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase on such date exceeds
10.0% of the total principal amount of the Notes to be purchased on the Closing Date, and any remaining non-defaulting Initial Purchaser shall not be obligated to purchase more than 110% of the principal amount of the Notes that it agreed to
purchase on the Closing Date pursuant to the terms of Section 3. If the foregoing maximums are exceeded, the remaining non-defaulting Initial Purchasers, or those other initial purchasers satisfactory to the Representatives who so agree, shall
have the right, but shall not be obligated, to purchase, in such proportion as may be agreed upon among them, all the Notes to be purchased on the Closing Date. If the remaining Initial Purchasers or other initial purchasers satisfactory to the
Representatives do not elect to purchase the Notes that the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase on the Closing Date, this Agreement shall terminate without liability on the part of any non-defaulting
Initial Purchaser, the Issuer or, upon execution of the Joinder Agreement, the Company or the Guarantors. As used in this Agreement, the term “Initial Purchaser” includes, for all purposes of this Agreement unless the context requires
otherwise, any party not listed in Schedule 1 hereto that, pursuant to this Section 10, purchases Notes that a defaulting Initial Purchaser agreed but failed to purchase. 

Nothing contained herein shall relieve a defaulting Initial Purchaser of any liability it may have to the Issuer or,
upon execution of the Joinder Agreement, the Company or 

 
 41
 
  

 
the Guarantors for damages caused by its default. If other Initial Purchasers are obligated or agree to purchase the Notes of a defaulting or withdrawing Initial Purchaser, either the
Representatives or the Company may postpone the Closing Date for up to seven full business days in order to effect any changes that in the opinion of counsel for the Issuer and the Company or counsel for the Initial Purchasers may be necessary in
the Pricing Disclosure Package, the Offering Memorandum or in any other document or arrangement. 

11.    Termination.  The obligations of the Initial Purchasers hereunder may
be terminated by the Representatives, by notice given to and received by the Issuer, prior to delivery of and payment for the Notes if, prior to that time, any of the events described in Sections 8(t), 8(u) or 8(v) shall have occurred or if the
Initial Purchasers shall decline to purchase the Notes for any reason permitted under this Agreement. 

12.    Research Analyst Independence.    The Issuer and, upon
execution of the Joinder Agreement, the Company and the Guarantors acknowledge that the Initial Purchasers’ research analysts and research departments are required to be independent from their respective investment banking divisions and are
subject to certain regulations and internal policies, and that such Initial Purchasers’ research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to the Issuer, Company, the
Guarantors and/or the offering that differ from the views of their respective investment banking divisions. The Issuer and, upon execution of the Joinder Agreement, the Company and the Guarantors hereby waive and release, to the fullest extent
permitted by law, any claims that the Issuer or, upon execution of the Joinder Agreement, the Company or any of the Guarantors may have against the Initial Purchasers with respect to any conflict of interest that may arise from the fact that the
views expressed by their independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Issuer, the Company or the Guarantors by such Initial Purchasers’ investment
banking divisions. The Issuer and, upon execution of the Joinder Agreement, the Company and the Guarantors acknowledge that each of the Initial Purchasers is a full service securities firm and as such from time to time, subject to applicable
securities laws, may effect transactions for its own account or the account of its customers and hold long or short positions in debt or equity securities of the companies that may be the subject of the transactions contemplated by this Agreement.

 13.    No Fiduciary Duty.  The Issuer and, upon execution of the
Joinder Agreement, the Company and the Guarantors acknowledge and agree that in connection with this offering, sale of the Notes or any other services the Initial Purchasers may be deemed to be providing hereunder, notwithstanding any preexisting
relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the Initial Purchasers: (i) no fiduciary or agency relationship between the Issuer, the Company, the
Guarantors and any other person, on the one hand, and the Initial Purchasers, on the other, exists; (ii) the Initial Purchasers are not acting as advisors, expert or otherwise, to the Issuer, the Company or the Guarantors, including, without
limitation, with respect to the determination of the public offering price of the Notes, and such relationship between the Issuer, the Company or any of the Guarantors, on the one hand, and the Initial Purchasers, on the other, is entirely and
solely commercial, based on arms-length negotiations; (iii) any duties and obligations that the Initial Purchasers may have to the Issuer, the Company or the Guarantors shall be limited to those duties and obligations specifically stated
herein; and (iv) the Initial Purchasers and their 

 
 42
 
  

 
respective affiliates may have interests that differ from those of the Issuer, the Company and the Guarantors. The Issuer and, upon execution of the Joinder Agreement, the Company and the
Guarantors hereby waive any claims that the Issuer or, upon execution of the Joinder Agreement, the Company or the Guarantors may have against the Initial Purchasers with respect to any breach of fiduciary duty in connection with this offering.

 14.    Notices, Etc.    All statements, requests,

and provisions hereof are for the sole benefit of only those persons, except that (A) the representations, warranties, indemnities and agreements of the Issuer and, upon execution of the Joinder Agreement, the Company and the Guarantors

 16.    Survival.  The
respective indemnities, rights of contribution, representations, warranties and agreements of the Issuer, the Company (upon execution of the Joinder Agreement), the Guarantors (upon execution of the Joinder Agreement) and the Initial Purchasers

 EXHIBIT A-1A 

Form of Opinion of Morrison & Foerster LLP, Counsel for the Issuer and the Company 

1.          The Issuer has been duly incorporated and is validly
existing and in good standing under the laws of Delaware, with full corporate power and authority to own its properties and conduct its business as described in the Pricing Disclosure Package and the Offering Memorandum, and to perform its
obligations under, the Purchase Agreement, the Escrow Agreement, the Indenture, the Notes and the Registration Rights Agreement. 
 2.          The Notes, the Indenture (including the Guarantee therein), the Registration Rights Agreement and the Escrow Agreement conform in all material
respects to the descriptions thereof contained in the Pricing Disclosure Package and the Offering Memorandum. 

3.          The Purchase Agreement has been duly authorized, executed
and delivered by the Issuer. 
 4.          Each of the Escrow
Agreement, the Indenture and the Registration Rights Agreement has been duly authorized, executed and delivered by the Issuer and constitutes a valid and binding agreement of the Issuer enforceable against the Issuer in accordance with its terms.

 5.          The Notes have been duly authorized, executed
and delivered by the Issuer and when executed and authenticated by the Trustee in accordance with the provisions of the Indenture and delivered against payment therefor pursuant to the terms of the Purchase Agreement and the Indenture, will
constitute valid and binding obligations of the Issuer entitled to the benefits of the Indenture and enforceable against the Issuer in accordance with their terms. 

6.          The Exchange Notes have been duly authorized for issuance
in the Exchange Offer, and when executed and authenticated in accordance with the terms of the Exchange Offer, the Registration Rights Agreement, and the Indenture, will constitute valid and binding obligations of the Company entitled to the
benefits of the Indenture and enforceable against the Company in accordance with their terms. 

7.          No consent, approval, authorization or other order of, or
registration or filing with, any court or other governmental or regulatory authority or agency is required for the execution, delivery and performance of the Purchase Agreement, the Escrow Agreement, the Indenture, the Notes or the Registration
Rights Agreement, in each case, by the Issuer, or the issuance and delivery of the Notes by the Issuer, or, as it relates to the Issuer, consummation of the transactions contemplated by the Purchase Agreement, the Escrow Agreement, the Registration
Rights Agreement, the Indenture, the Pricing Disclosure Package and the Offering Memorandum, except such as may be required under the Act, the Trust Indenture Act or the blue sky laws of any jurisdiction in connection with the offer, sale and
distribution of the Notes by the Initial Purchasers and except for such approvals from the Federal Trade Commission or any gaming regulatory authority in connection with the consummation of any transactions contemplated by the Pricing Disclosure
Package and Offering Memorandum. 
 8.          None of the
execution and delivery of the Purchase Agreement, the Escrow Agreement, the Indenture, the Registration Rights Agreement, the issue and sale of the Notes, 

  
 Exhibit A-1A-1

 
nor the consummation of any other of the transactions contemplated by the Purchase Agreement nor the fulfillment of the terms thereof will result in a breach or violation of, or constitute a
default under (i) any law or the certification of incorporation or bylaws of the Issuer, (ii) any indenture, mortgage, loan or credit agreement, note or other debt instrument to which the Issuer is a party or by which it may be bound, or
to which any of the property or assets of the Issuer is subject, in each case which is identified to us by an officer of the Issuer in the officer’s certificate attached hereto as Exhibit B (the “Officer’s Certificate”) , or
(iii) any judgment, order or decree of any court, regulatory body, administrative agency, governmental body or arbitrator having jurisdiction over the Issuer which is identified in the Officer’s Certificate. 

9.          Each of the reports filed by the Company under the Exchange
Act and incorporated by reference into the Offering Memorandum (other than (i) the financial statements and supporting schedules and other financial data included therein and (ii) opinions on internal controls and compliance therewith, as
to which we express no opinion), when they were filed with the Commission (or, if later, upon filing of an amendment thereto) complied as to form in all material respects with the requirements of the Exchange Act. 

10.        The statements in the Pricing Disclosure Package and the Offering
Memorandum under the captions “Description of other indebtedness,” “Description of notes,” and “Material federal income tax considerations,” insofar as such statements constitute summaries of legal matters or matters of
law, fairly and accurately present and summarize, in all material respects, the matters referred to therein. 

11.        Assuming (i) the accuracy of, and compliance with, the
representations, warranties and covenants of the Issuer in the Purchase Agreement, (ii) the accuracy of, and compliance with, the representations, warranties and covenants of the Initial Purchasers in the Purchase Agreement and the Pricing
Disclosure Package, and (iii) the compliance by the Initial Purchasers with the offering and transfer procedures and restrictions described in the Purchase Agreement, the Pricing Disclosure Package and the Offering Memorandum, it is not
necessary in connection with the offer, sale and delivery of the Notes in the manner contemplated by the Purchase Agreement to register the Notes under the Act or to qualify the Indenture under the Trust Indenture Act (it being understood that we
express no opinion with respect to any subsequent resale of the Notes other than the Exempt Resales). 

12.        The Issuer is not and, after giving effect to the offering and sale of
the Notes and the application of the net proceeds thereof as described in the Pricing Disclosure Package and the Offering Memorandum, will not be, an “investment company” as such term is defined in the Investment Company Act of 1940, as
amended. 
 13.        Assuming the proceeds of the sale of the Notes
are used for the purposes set forth in the Pricing Disclosure Package and the Offering Memorandum, such use of proceeds will not violate the provisions of Regulation T, U or X of the Board of Governors of the Federal Reserve. 

14.        The Escrow Agreement is effective to create a security interest in
favor of the Trustee for its benefit and for the ratable benefit of the holders of the Notes in the rights of the Issuer in the Collateral as security for the Obligations (as defined in the Escrow Agreement). 

  
 Exhibit A-1A-2

 15.        The Financing Statement
is in appropriate form for filing as a financing statement with the Office of the Secretary of State of the State of Delaware pursuant to the DUCC. 
 16.        Upon the filing of the Financing Statement with the Office of the Secretary of State of the State of Delaware, the Trustee will have a perfected security
interest (for the ratable benefit of the holders of the Notes) securing the Obligations in the Issuer’s rights in that part of the Collateral under the Escrow Agreement in which a security interest can be perfected by the filing of a financing
statement in the State of Delaware. 
 17.        The execution and
delivery by the parties thereto of the Escrow Agreement operates to perfect the security interest of the Trustee (for its benefit and for the ratable benefit of the holders of the Notes) in the rights of the Issuer in the Escrow Account as security
for the Obligations. 

  
 Exhibit A-1A-3

 EXHIBIT A-1B 

Form of Negative Assurance Letter of Morrison & Foerster LLP, Counsel for the Issuer and the Company 

This letter is furnished to the Initial Purchasers pursuant to Section 8(c) of the Purchase Agreement. Capitalized terms used herein
and not otherwise defined shall have the respective meanings assigned to them in the Purchase Agreement. 
 We have participated
in conferences with officers and other representatives of the Issuer, the Company and Ameristar Casinos, Inc. (“Ameristar”) and representatives of the independent public accountants for the Company and Ameristar and with
representatives of the Initial Purchasers and their counsel concerning the Pricing Disclosure Package and the Offering Memorandum, and have considered the matters required to be stated therein and the statements contained therein. 

The purpose of our professional engagement was not to establish or confirm factual matters set forth in the Pricing Disclosure Package
and the Offering Memorandum, and we have neither verified independently the accuracy, completeness or fairness of any such factual matters, nor have we undertaken to do any such action (except as otherwise specified in paragraphs (b) and
(j) of our opinion of even date herewith). We are also not passing upon, and do not assume any responsibility for, ascertaining whether or when any of the information contained in the Pricing Disclosure Package was conveyed to any purchaser of
the Notes. Moreover, many of the determinations required to be made in the preparation of the Pricing Disclosure Package and the Offering Memorandum involve matters of a non-legal nature. 

Based upon and subject to the foregoing, nothing has come to our attention that leads us to believe that: (i) the Pricing Disclosure
Package (including the documents incorporated by reference therein), taken as a whole, at the Applicable Time, contained an untrue statement of a material fact or omitted to state a material fact necessary to make the statements therein, in the
light of circumstances under which they were made, not misleading; or (ii) the Offering Memorandum (including the documents incorporated by reference therein), as of its date or at the Closing Date, contained or contains an untrue statement of
a material fact or omitted or omits to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading (it being understood that we have not been asked to and do not make
any comment pursuant to this paragraph with respect to the financial statements (including the notes thereto), supporting schedules and other financial data included or incorporated by reference in the Pricing Disclosure Package or the Offering
Memorandum or any amendments or supplements thereto). 
 This letter is solely for the Initial Purchasers’ benefit and may
not be relied upon by, nor may copies be delivered to, any other person or entity without our prior written consent. 

  
 Exhibit A-1B-1

 EXHIBIT A-2 

Form of Opinion of Brownstein Hyatt Farber Schreck, LLP, Nevada Counsel for the 

Company and Ameristar 
 1.          Based solely on our review of the PNK Good Standing Certificate, the Company is qualified to do business as a foreign corporation and is in
good standing in the State of Nevada. 
 2.          Ameristar
is validly existing as a corporation and in good standing under the laws of the State of Nevada.

securities intermediary or financial intermediary, that becomes the registered owner of such uncertificated securities on behalf of the Escrow Agent and acknowledges that it holds the same for
the Escrow Agent; and (ii) in the case of Collateral Investments in the form of Temporary Cash Investments, the making of book entries by the securities intermediary (other than a clearing corporation) to whose account such Temporary Cash
Investments have been credited on the books of a Federal Reserve Bank (or on the books of another such securities intermediary (other than a clearing corporation)) indicating that such Temporary Cash Investments have been credited to an account of
the Escrow Agent, and the sending by such securities intermediary to the Escrow Agent of confirmation of such transfer to the Escrow Agent’s account, in each case, as applicable depending on the nature of the Temporary Cash Investment.

  

	5.3	 Prior to or concurrently with the execution and delivery of this Agreement and prior to the transfer to the Escrow Agent of Collateral Investments
(or acquisition by the Escrow Agent of any security entitlement thereto) the Escrow Agent shall establish the Escrow Account on its books as an account segregated from all other custodial or collateral accounts. All Collateral Investments shall be
credited to the Escrow Account, and the Escrow Agent hereby agrees to treat all property credited to the Escrow Account as a “financial asset” as defined in Section 8-102(a)(9) of the UCC. Subject to the other terms and conditions of
this Agreement, all Collateral Investments held by the Escrow Agent pursuant to this Agreement shall be held in the Escrow Account subject (except as expressly provided in Sections 6.1 and 6.2 hereof) to the control (within the meaning of Sections
8-106 and 9-106 of the UCC) of the Trustee for the ratable benefit of the holders of the Notes and segregated from all other funds or other property otherwise held by the Escrow Agent.

hereto as Exhibit A executed by authorized representatives of the Company and containing the certifications described therein, the Escrow Agent shall [, on the later of (i) the same day (or, if such date is not a Business Day, the first
Business Day after such date) following receipt by the Escrow Agent of such certificate or (ii) the date specified in such certificate (or, if such date is not a Business Day, the first Business Day after such date)]1 liquidate, at the written direction of the Grantor, all investments
of Escrowed Funds then held by it (subject to Section 18 hereof) and disburse from the Escrow Account to such Person(s) or account(s) as specified in such certificate, all Escrowed Funds held in the Escrow Account. Any certificate delivered to
the Escrow Agent pursuant to this Section 6.2 shall be simultaneously delivered to the Trustee; provided that failure to so deliver such

 - 8 -

	 	 
certificate shall not invalidate or in any manner affect delivery of such certificate to the Escrow Agent.

Section 3.10 of the Indenture, the Escrow Agent shall liquidate all investments of Escrowed Funds then held by it (subject to Section 18 hereof) not later than the last Business Day prior to the Special Mandatory Redemption Date. On the
Business Day prior to the Special Mandatory Redemption Date, the Escrow Agent shall release all Escrowed Funds prior to 11:00 a.m. (New York City time) as follows:

	 	(b)	 second, to the Grantor or its designee or designees, any Escrowed Funds remaining after the above distributions;

 The Notes shall be redeemed as specified in Article 3 of the Indenture. 

 

	6.4	 If the Trustee is required to effect the redemption contemplated by Section 3.10 of the Indenture and Section 6.3 above and for any reason
the amount of Collateral to be released is insufficient to pay the Special Mandatory Redemption Price to redeem all of the outstanding Notes as provided in Section 3.10 of the Indenture, the Grantor agrees to pay to the Trustee, no less than
one Business Day prior to the Special Mandatory Redemption Date, the amount of funds necessary to permit all outstanding Notes to be redeemed in accordance with the provisions of the Indenture. 

 

	6.5	 Upon the release of any Collateral from the Escrow Account in accordance with the terms of this Agreement, the security interest evidenced by this
Agreement in such released Collateral will automatically terminate without any further action and such security interest will be of no further force and effect. Such released Collateral will be delivered to the recipient free and clear of any and
all liens, claims or encumbrances of any Person, including, without limitation, the Escrow Agent, the Trustee and the holders of the Notes. The Escrow Agent and Trustee will take, and hereby authorize the Grantor to take, all steps necessary to
terminate any UCC financing statements and will execute such other documents without recourse, representation or warranty of any kind as the Grantor may reasonably request in writing to evidence or confirm the termination of the security interest in
such released Collateral. 

  

	6.6	 The Escrow Agent shall not be required to liquidate any Collateral Investment in order to make any release hereunder unless (i) required to do
so to effect any distribution pursuant to Section 6.2 or 6.3 hereof; or (ii) instructed to do so by written instructions executed by the Grantor.

expenses due to the Escrow Agent pursuant to Section 9 hereof and other amounts owed to the Escrow Agent pursuant to Section 7.3 and Section 8.4 hereof as of the date of such request; and (ii) the Trustee shall provide the
Grantor the amount of fees, reasonable out-of-pocket expenses of the Trustee, indemnities and other amounts owed to the Trustee under the Indenture as of the date of such request.

Agent may be required by the Internal Revenue Code of 1986, as amended, and the regulations promulgated thereunder, to withhold a portion of any interest or other income earned on the investment of the Escrowed Funds. 

 

	7.3	 To the extent that the Escrow Agent becomes liable for the payment of any taxes in respect of income derived from the investment of the Escrowed
Funds, the Escrow Agent shall satisfy such Liability from the Escrowed Funds to the extent funds are available pursuant to the terms of this Agreement. The Grantor hereby indemnifies, defends and holds the Escrow Agent harmless from and against any
tax, late payment, interest, penalty or other cost or expense that may be assessed against the Escrow Agent on or with respect to the Escrowed Funds and the investment thereof unless such tax, late payment, interest, penalty or other expense was
directly caused by the gross negligence, fraud or wilful misconduct of the Escrow Agent. Payment pursuant to this Section 7.3, shall be made by the Grantor within 60 days of receipt of written demand from the Escrow Agent.

  

	7.4	 The sole tax reporting obligation of the Escrow Agent hereunder shall be to file appropriate versions of Forms 1099-INT with the Internal Revenue

	8.	 DUTIES OF THE ESCROW AGENT AND INDEMNIFICATION 

 

	8.1	 The duties of the Escrow Agent are purely ministerial in nature and its sole obligation shall be to perform the duties specifically set forth in
this Agreement. Under no circumstances will the Escrow Agent be deemed to be a fiduciary to any Party or any other Person under this Agreement. Except as provided in Section 8.9, the Escrow Agent will not be responsible or liable for the
failure of any Party to perform in accordance with this Agreement. The Escrow Agent shall neither be responsible for, nor chargeable with, knowledge of the terms and conditions of any other agreement, instrument, or document other than this
Agreement, whether or not an original or a copy of such agreement has been provided to the Escrow Agent; and the Escrow Agent shall have no duty to know or inquire as to the performance or nonperformance of any provision of any such agreement,
instrument, or document. References in this Agreement to any other agreement, instrument, or document are for the convenience of the Parties, and the Escrow Agent has no duties or obligations with respect thereto. This Agreement sets forth all
matters pertinent to the escrow contemplated hereunder, and no additional obligations of the Escrow Agent shall be inferred or implied from the terms of this Agreement or any other agreement. 

 

	8.2	 The Escrow Agent shall be entitled to rely on and shall not be liable for any action taken or omitted to be taken in accordance with the advice of
counsel retained by the Escrow Agent. The Escrow Agent shall be reimbursed as set forth in Sections 8.4 and 9.1 hereof for any and all compensation (fees, expenses and other costs) paid and/or reimbursed to such counsel and/or professionals.

  

	8.3	 The Escrow Agent shall not be liable or responsible for any Liabilities or inconvenience which may result from anything done or omitted to be done
by it in accordance with this Agreement and shall bear no obligation or responsibility to any Person in respect of the operation of the Escrow Account, unless such Liability arises as a result of the gross negligence, fraud or wilful misconduct of
the Escrow Agent. The Escrow Agent is not responsible for the validity or legality of any transaction associated with any of the Escrowed Funds. 

  

	8.4	 The Grantor hereby indemnifies and holds harmless the Escrow Agent for an amount equal to any and all Liabilities or obligations of any kind
whatsoever that may be imposed on or incurred by the Escrow Agent in connection with any action, claim or proceeding brought against the Escrow Agent arising out of or relating in any way to this Agreement; provided that the Grantor shall not
have any obligation to indemnify the Escrow Agent for any claims arising as a result of the gross negligence, fraud or wilful misconduct of the Escrow Agent. The provisions of this Section 8.4 shall survive the resignation or removal of the
Escrow Agent and the termination of this Agreement. 

  

	8.5	 In no event shall the Escrow Agent be responsible or liable for any punitive, special, indirect, or consequential loss or damage of any kind
whatsoever (including, without limitation, loss of profit) irrespective of whether the Escrow Agent has been advised of the likelihood of such loss or damage and regardless of the form of action. The Escrow Agent shall not be responsible or liable
for any failure or delay in the performance of its 

  
 - 11 -

	 	 
obligations under this Agreement arising out of or caused, directly or indirectly, by circumstances beyond its reasonable control, including without limitation, acts of God, earthquakes, fires,
floods, wars, civil or military disturbances, sabotage, epidemics, riots, interruptions, loss or malfunctions of utilities, computer (hardware or software) or communications service, accidents, labor disputes, acts of civil or military authority or
governmental actions (it being understood that the Escrow Agent shall use its best efforts to resume performance as soon as practicable under the circumstances). 

 

	8.6	 The Escrow Agent shall not be liable for acting upon, and shall be entitled to rely on and treat as a genuine document, any document that it
reasonably believes in good faith to be a notice, direction or other document furnished to it by any Party or any legal counsel of a Party in writing and by whatever means without further investigation and believed by the Escrow Agent in its
absolute discretion to be genuine and to have been signed by the proper persons. 

  

	8.7	 In the event that the Escrow Agent is of the reasonable opinion that it is unclear how it is required to act hereunder, it may, in its absolute
discretion and without being liable for any Liability resulting therefrom refrain from acting pending receipt to its satisfaction of such clarification or a final and non-appealable order or judgment of a court of competent jurisdiction. Upon
initiating any action of interpleader or any other action, the Escrow Agent shall be fully released and discharged from all obligations and liability imposed by the terms of this Agreement. Furthermore it shall be entitled to seek and rely upon, and
shall be protected in acting in good faith upon, the advice or opinion of, or any information addressed to the Escrow Agent obtained from any lawyer and shall not be liable for any Liability occasioned by so acting (or for any delay or inaction
pending the obtaining of such advice or opinion in good faith), except to the extent that such Liability is due to the Escrow Agent’s gross negligence, fraud or wilful misconduct. 

 

	8.8	 The Escrow Agent is hereby authorized, in making or disposing of any investment permitted by this Agreement, to deal with itself (in its individual
capacity) or with anyone or more of its affiliates, so long as such action is in a manner not inconsistent with the terms of this Agreement. 

  

	8.9	 The Escrow Agent may execute any of its powers or responsibilities hereunder either directly or by or through its agents or attorneys and the Escrow
Agent shall not be liable for the actions of any agents or attorneys appointed with due care. Any such acts by the Escrow Agent’s agents or attorneys will be deemed to be acts of the Escrow Agent, and shall not relieve the Escrow Agent of any
of its duties, responsibilities or obligations hereunder. 

  

	9.	 FEES AND EXPENSES 

  

	9.1	 The Grantor shall pay to the Escrow Agent reasonable and documented out-of-pocket expenses and disbursements to the extent then invoiced (including
documentation supporting such requests), including reasonable legal expenses of one legal counsel. The Escrow Agent has waived all other reasonable activity charges, including any annual fees, acceptance fees and reasonable costs and expenses, which
the Escrow Agent may properly incur in relation to the negotiation, preparation and execution of this Agreement and the performance of its obligations hereunder. Any extraordinary fees properly incurred pursuant to Section 9.2 have not been
waived. 

  
 - 12 -

	9.2	 If the Escrow Agent considers it expedient or necessary to undertake duties which are of an exceptional nature or otherwise outside the scope of the
normal duties of the Escrow Agent under this Agreement, and the Escrow Agent undertakes such duties with the prior written consent of the Grantor, the Grantor shall pay to the Escrow Agent additional remuneration in accordance with the Escrow
Agent’s then current charging procedures. 

  

	9.3	 All payments by the Grantor under this Section 9 shall be made free and clear of, and without withholding or deduction for, any taxes, duties,
assessments or governmental charges of any nature imposed by any government having power to tax, unless such withholding or deduction is required by law. In that event, the Grantor shall pay such additional amounts as will result in receipt by the
Escrow Agent of such amounts as would have been received by it if no such withholding had been required. 

  

	9.4	 Any payment under this Section 9 shall be made within 30 days of the date of receipt of the relevant invoice (including documentation
reasonably supporting such requests) by the Grantor. 

  

	10.	 MODIFICATION 

 No modification to or variation of this Agreement (or any document entered into pursuant to this Agreement) shall be valid unless it is in writing and signed by or on behalf of each Party hereto and the
prior written consent of the Initial Purchasers to such modification or variation has been obtained. Notwithstanding the foregoing, no provisions of this Agreement (including, without limitation, those relating to the release of the Escrowed Funds
under Section 6 hereof) may be modified in any manner materially adverse to the holders of the Notes without the written consent of the holders of a majority in principal amount of the Notes then outstanding voting as a single class.

  

	11.	 TERMINATION 

  

	11.1	 This Agreement shall terminate upon the distribution of all Escrowed Funds from the Escrow Account in accordance with the provisions of
Section 6. At such time and upon the written instruction of the Trustee, the Escrow Agent shall reassign and redeliver to the Grantor all of the Collateral hereunder that has not been sold, disposed of, retained or applied by the Escrow Agent
in accordance with the terms of this Agreement and the Indenture. Such reassignment and redelivery to the Grantor shall be without warranty by or recourse to the Escrow Agent in its capacity as such, except as to the absence of any liens on the
Collateral created by or on account of actions of the Escrow Agent, and shall be at the reasonable expense of the Grantor. 

  

	11.2	 Sections 8 and 9 hereof shall survive the termination of this Agreement. 

 

	12.	 CHANGE IN ESCROW AGENT 

  

	12.1	 Each of the Parties agrees that the Grantor may terminate the appointment of the Escrow Agent hereunder at any time by giving 10 days’ advance
written notice of such termination to the Escrow Agent, signed by the Grantor. 

  
 - 13 -

	12.2	 Each of the Parties agrees that the Escrow Agent shall have the right to give notice of the resignation of its appointment hereunder by giving 30
days’ advance written notice to that effect to the other Parties. Such notice shall specify the date on which such resignation shall take effect (the “Effective Resignation Date”); provided, however, the
assignment by the Escrow Agent pursuant to Section 13.3 hereof shall not require any such advance notice. 

  

	12.3	 In the event that the Escrow Agent delivers a notice in accordance with Section 12.2 above, the Grantor shall appoint a successor escrow agent
on substantially the same terms as this Agreement. Following the transfer of the Escrowed Funds to any designated successor escrow agent or other designated party, the Escrow Agent shall automatically be discharged from its obligations under this
Agreement. 

  

	12.4	 If, prior to the Effective Resignation Date, the other Parties have not appointed a successor escrow agent or instructed the Escrow Agent to
transfer the Escrowed Funds in accordance with Section 12.3 above, the Escrow Agent may petition a court of competent jurisdiction to approve a successor escrow agent. Any such appointment shall be binding upon all of the Parties hereto and the
Escrow Agent shall be entitled to transfer the Escrowed Funds to the successor escrow agent so appointed, at which such time the Escrow Agent’s obligations hereunder shall terminate. 

 

	13.	 ASSIGNMENT 

  

	13.1	 Nothing in this Agreement, expressed or implied, shall give or be construed to give any Person, other than the Parties hereto and their respective
successors and assigns, any legal claim under any covenant, condition or provision hereof, all the covenants, conditions and provisions contained in this Agreement being for the sole benefit of and only binding upon the Parties hereto and their
respective successors and assigns. 

  

	13.2	 Other than an assignment of this Agreement by the Grantor to the Company by merger in connection with the Acquisition, no Party shall assign,
transfer, or create security over all or any of its rights or obligations under this Agreement without the prior written consent of the other Parties, which consent may be withheld in the sole discretion of the Party whose consent is sought. Any
purported assignment, transfer or security without that consent shall be null and void and of no force or effect. 

  

	13.3	 If the Escrow Agent consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another
corporation or banking association, the successor corporation or association without any further act pursuant to Section 13.2, so long as such corporation or banking association is a nationally recognized financial institution, shall be the
successor Escrow Agent. 

  

	14.	 COUNTERPARTS 

 This Agreement may be executed in one or more counterparts, each of which will be deemed to be an original copy of this Agreement and all of which, when taken together, will be deemed to constitute one
and the same agreement. 
  

	15.	 ENTIRE AGREEMENT 

  
 - 14 -

 This Agreement represents the whole agreement among the Parties in relation
to its subject matter and supersedes all prior representations, promises, agreements and understandings. The invalidity, illegality or unenforceability of a provision of this Agreement does not affect or impair the continuation in force of the
remainder of it.

Trustee. The Escrow Agent agrees to accept and act upon instructions or directions pursuant to this Agreement sent by unsecured e-mail, pdf, facsimile transmission or other similar unsecured electronic methods; provided, however, that
the Escrow Agent shall have received an incumbency certificate listing persons designated to give such instructions or directions and containing specimen signatures of such designated persons, which such incumbency certificate shall be amended and
replaced whenever a person is to be added or deleted from the listing. If the parties hereto elect to give the Escrow Agent e-mail or facsimile instructions (or instructions by a similar electronic method) and the Escrow Agent in its discretion
elects to act upon such instructions, the Escrow Agent’s understanding of such instructions shall be deemed controlling. The Escrow Agent shall not be liable for any losses, costs or expenses arising directly or indirectly from the Escrow
Agent’s reliance upon and compliance with such instructions notwithstanding if such instructions conflict or are inconsistent with a subsequent written instruction. The Grantor agrees to assume all risks arising out of the use of such
electronic methods to submit instructions and directions to the Escrow Agent, including without limitation the risk of the Escrow Agent acting on unauthorized instructions, and the risk or interception and misuse by third parties.

	17.1	 THIS AGREEMENT AND ANY NON-CONTRACTUAL OBLIGATIONS ARISING OUT OF OR IN CONNECTION WITH IT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE
LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAWS TO THE EXTENT THAT THE APPLICATION OF THE LAW OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY. 

 

	17.2	 Each Party hereto irrevocably (i) agrees that any legal suit, action or proceeding against such Party arising out of or based upon this
Agreement or the transactions contemplated hereby may be instituted in any U.S. Federal or state court in the Borough of Manhattan, The City of New York and (ii) waives, to the fullest extent it may effectively do so, any objection which it may
now or hereafter have to the laying of venue of any such proceeding. 

  

	17.3	 The Parties agree that if any provision of this Agreement shall under any circumstances be deemed invalid or inoperative, this Agreement shall be
construed with the invalid or 

  
 - 16 -

	 	 
inoperative provisions deleted and the rights and obligations of the Parties shall be construed and enforced accordingly. 

 

	17.4	 The headings used in this Agreement are for convenience only and shall not constitute a part of this Agreement. Each of the parties hereto hereby
irrevocably waives to the fullest extent permitted by applicable law any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement. 

 

	18.	 WIRE TRANSFER INSTRUCTIONS 

  

	18.1	 All cash deposited into the Escrow Account by any Person will be transferred by wire transfer (except for transfers to the Escrow Account by the
Trustee which may be by book entry) of immediately available funds in accordance with wire instructions set forth in Schedule A-1. 

  

	18.2	 All cash (including the cash proceeds from liquidation of any Escrowed Funds) distributed from the Escrow Account to any Person will be transferred

A-2, which shall be superseded by any amendments thereto or such other schedules provided subsequent to the execution of this Agreement, prior to such distribution. 

 

	18.3	 If, upon termination of this Agreement and after any required liquidation or distribution of Escrowed Funds for the benefit of any Person other than
the Grantor, pursuant to Section 6 hereof, any Escrowed Funds consist of assets other than cash and are to be released to the Grantor, the Escrow Agent shall liquidate such Escrowed Funds into cash and distribute it pursuant to Section 6.3
hereof unless the Grantor has provided a prior written request to the Escrow Agent not to liquidate such Escrowed Funds and to deliver such non-cash Escrowed Funds in kind to the Grantor, to the extent the Grantor is entitled to a distribution, at
such account(s) or location(s) specified by the Grantor in such written request. If the Escrow Agent receives such a request, it shall deliver such non-cash Escrowed Funds to the Grantor as promptly as practicable. No request by the Parties pursuant
to this paragraph shall constitute an “entitlement order” or instruction with respect to the Escrowed Funds prior to the termination of this Agreement.

 Schedule B 
 CUSTOMER IDENTIFICATION PROGRAM NOTICE 
 Important information
about procedures for opening a new Account 
 To help the government fight the funding of terrorism and money laundering activities, Federal
law requires all financial institutions (which includes the Escrow Agent) to obtain, verify and record information that identifies each Person who opens an account. 
 For a non-individual Person such as a business entity, a charity, a trust or other legal entity, the Escrow Agent will ask for documentation to verify its formation and existence as a legal entity. Such
documentation may include, but is not limited to, Certificates of Good Standing from the appropriate Secretary of State, certified copies of Partnership Agreements, Trust Agreements or other formation agreements or documents. For companies whose
equity securities are publicly traded, these requirements can be met with evidence of regulatory filings with the Securities and Exchange Commission as found on its EDGAR database. We may also ask to see financial statements, licenses,
identification and authorization documents from individuals claiming authority to represent the entity or other relevant documentation. 
 In
addition, for non-individual entities, the Escrow Agent must be informed if any contractual party is now acting, or has acted in the past 12 months, under a different name, or has changed its name in the last 12 months. 

For individuals, a copy of a government–issued identification, such as a driver’s license or passport, is required to establish identity for
the primary party responsible for the account as a signing party to the governing documents. Additionally, any individual involved in the transaction will be required to provide a certified Tax Identification Number on IRS Form W-9, or Form W-8 for
non-US Persons. 
 Any capitalized term used without definition in this Schedule B is used with the meaning assigned to such term in the
Escrow Agreement of which this Schedule B is a part.

 ARTICLE I 

AMENDMENT OF INDENTURE 
 Section 1.1 Amendment to Definitions. Section 1.2 of the Supplemental Indenture is hereby amended as follows. 
 (a) The following definitions are hereby inserted alphabetically into Section 1.2 of the Supplemental Indenture: 
 “Parent” means any person of which the Company at any time is a subsidiary, or at any time after the issue date of the Notes becomes a subsidiary, and any holding company established by
any Permitted Holder for purposes of holding its investment in any Parent. 

 “Permitted Holders” means, collectively, (1) Bain Capital Partners,
LLC, Golden Gate Private Equity, Inc., GIC Special Investments Pte Ltd, and Insight Venture Management, LLC, any of their respective successors and their respective Affiliates, (2) any one or more persons, together with such persons’
Affiliates, whose beneficial ownership constitutes or results in a Change of Control in respect of which a Change of Control Offer is made in accordance with the requirements of this Indenture, (3) any person who is acting as an underwriter in
connection with a public or private offering of Capital Stock of any Parent or the Company, acting in such capacity, and (4) any group (within the meaning of Section 13(d)(3) or Section 14(d)(2) of the Exchange Act or any successor
provision) of which any of the foregoing are members; provided that, in the case of such “group” and without giving effect to the existence of such group or any other group, any one or more of the persons specified in (1),
collectively, has beneficial ownership of more than 50% of the total voting power of the Voting Stock of the Company or any of its Parents held by such “group.” 
 (b) The definition of “Change of Control is hereby amended and restated in its entirety as follows: 
 “Change of Control” means the occurrence of any of the following: 

(1) the direct or indirect sale, transfer, conveyance or other disposition (other than by way of merger or consolidation), in one or more
series of related transactions, of all or substantially all of the Company’s assets and the assets of its Subsidiaries, taken as a whole, to any person, other than the Company, one of its Subsidiaries, or one or more Permitted Holders;

 (2) the consummation of any transaction (including, without limitation, any merger or consolidation) the result of which is
that any person, other than one or more Permitted Holders, becomes the beneficial owner (as defined in Rules 13d-3 and 13d-5 under the Exchange Act), directly or indirectly, of more than 50% of the Company’s outstanding Voting Stock or other
Voting Stock into which the Company’s Voting Stock is reclassified, consolidated, exchanged or changed, measured by voting power rather than number of shares; 
 (3) the Company consolidates with, or merges with or into, any person other than a Permitted Holder, or any person other than a Permitted Holder consolidates with, or merges with or into, the Company, in
any such event pursuant to a transaction in which any of the Company’s outstanding Voting Stock or the Voting Stock of such other person is converted into or exchanged for cash, securities or other property, other than any such transaction
where the shares of the Company’s Voting Stock outstanding immediately prior to such transaction constitute, or are converted into or exchanged for, a majority of the Voting Stock of the surviving person or any direct or indirect parent company
of the surviving person immediately after giving effect to such transaction; 
 (4) the first day on which a majority of the
members of the Company’s Board of Directors are not Continuing Directors; or 
 (5) the adoption of a plan relating to the
Company’s liquidation or dissolution. 
 Notwithstanding the foregoing, a transaction will not be deemed to involve a
Change of Control if (1) the Company becomes a direct or indirect wholly owned Subsidiary of a holding company and (2)(A) the direct or indirect holders of the Voting Stock of such holding company immediately following that transaction are
substantially the same as the holders of the Company’s Voting Stock immediately prior to that transaction or (B) immediately following that transaction no person (other than a holding company satisfying the requirements of this sentence)
is the beneficial owner, directly or indirectly, of more than 50% of the Voting Stock of such holding company. The term “person,” as used in this definition, has the meaning given thereto in Section 13(d)(3) of the Exchange Act.
