1. REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

The Company represents and warrants to the Underwriters as follows:

(a) An “automatic shelf registration statement” as defined in Rule 405 under the Securities Act of 1933, as amended (the “Act”), on Form S-3 (File No. 333-234542) in respect of the Shares, including a form of prospectus (the “Base Prospectus”), has been prepared and filed by the Company not earlier than three years prior to the date hereof, in conformity with the requirements of the Act and the rules and regulations (the “Rules and Regulations”) of the Securities and Exchange Commission (the “Commission”) thereunder. The Company and the transactions contemplated by this Agreement meet the requirements and comply with the conditions for the use of Form S-3. Copies of such registration statement, including any amendments thereto, the Base Prospectus, as supplemented by any preliminary prospectus (including any preliminary prospectus supplement) relating to the Shares filed with the Commission pursuant to Rule 424(b) under the Act, and including the documents incorporated in the Base Prospectus by reference (a “Preliminary Prospectus”), and the exhibits, financial statements and schedules to such registration statement, in each case as finally amended and revised, have heretofore been delivered or made available to you. Such registration statement, together with any registration statement filed by the Company pursuant to Rules 413(b) and 462(f) under the Act, is herein referred to as the “Registration Statement,” which shall be deemed to include all information omitted therefrom in reliance upon Rules 430A, 430B or 430C under the Act and contained in the Prospectus referred to below, has become effective under the Act and no post-effective amendment to the Registration Statement has been filed as of the date of this Agreement. “Prospectus” means the form of prospectus relating to the Shares first filed with the Commission pursuant to and within the time limits described in Rule 424(b) under the Act and in accordance with Section 4(a) hereof. Any reference herein to the Registration Statement, any Preliminary Prospectus or to the Prospectus or to any amendment or supplement to any of the foregoing documents shall be deemed to refer to and include any documents incorporated by reference therein, and, in the case of any reference herein to the Prospectus, also shall be deemed to include any documents incorporated by reference therein, and any supplements or amendments thereto, filed with the Commission after the date of filing of the Prospectus under Rule 424(b) under the Act, and prior to the termination of the offering of the Shares by the Underwriters.

(b) As of the Applicable Time (as defined below) and as of the Closing Date or the Option Closing Date, as the case may be, neither (i) the General Use Free Writing Prospectus(es) (as defined below) issued at or prior to the Applicable Time, the Statutory Prospectus (as defined below) and any information included on Schedule II hereto, all considered together (collectively, the “General Disclosure Package”), nor (ii) any individual Limited Use Free Writing Prospectus (as defined below), when considered together with the General Disclosure Package, included or will include any untrue statement of a material fact or omitted or will 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, however, that the Company makes no representations or warranties as to information contained in or omitted from any Issuer Free Writing Prospectus, in reliance upon, and in conformity with, written information furnished to the Company by or on behalf of the Underwriters, specifically for use therein, it being understood and agreed that the only such information is that described in Section 12 herein. As used in this subsection and elsewhere in this Agreement:

“General Use Free Writing Prospectus” means any Issuer Free Writing Prospectus that is identified on Schedule II to this Agreement.

“Limited Use Free Writing Prospectus” means any Issuer Free Writing Prospectus that is not a General Use Free Writing Prospectus.

(c) The Company has been duly organized and is validly existing as a corporation in good standing under the laws of the State of Nevada, with corporate power and authority to own or lease and operate its properties and conduct its business as described in the Registration Statement, the General Disclosure Package and the Prospectus and as currently conducted and to enter into and to perform its obligations under this Agreement. Each of the “significant subsidiaries” (as that term is defined in clauses (1) and (2) of the definition of “Significant Subsidiaries” set forth in Rule 1-02(w) of Regulation S-X under the Act) of the Company is listed on Exhibit A hereto (each a “Significant Subsidiary,” and collectively, the “Significant Subsidiaries”) and has been duly organized and is validly existing as a corporation or limited liability company in good standing under the laws of the jurisdiction of its organization, with corporate or limited liability company power and authority to own or lease and operate its properties and conduct its business as described in the Registration Statement, the General Disclosure Package and the Prospectus. The Company does not own or control, directly or indirectly, any corporation, limited liability company, association or other entity, other than the subsidiaries listed in Exhibit 21.1 of the Company’s Annual Report on Form 10-K for the year ended December 31, 2019 incorporated by reference in the Registration Statement and any subsidiaries that, taken together, would not be a “significant subsidiary” of the Company as defined in Rule 1-02(w) of Regulation S-X under the Act. Each of the Company and its Significant Subsidiaries (collectively, the “Wynn Parties”) is duly qualified to transact business in all jurisdictions in which the conduct of its business requires such qualification, except for such jurisdictions where the failure to so qualify would not, individually or in the aggregate, reasonably be expected to result in any material adverse change in the management, business, properties, assets, operations, condition (financial or otherwise), prospects or results of operations of, the Wynn Parties, taken as a whole, whether or not occurring in the ordinary course of business (any such change, a “Material Adverse Change”).

(d) As of the date hereof, the authorized capital stock of the Company consists only of 400,000,000 shares of Common Stock, par value $0.01 per share and 40,000,000 shares of Preferred Stock, par value $0.01 per share. All issued and outstanding member’s interests and shares of capital stock of each of the Wynn Parties have been duly authorized and validly issued, the shares of capital stock are fully paid and non-assessable, and the member’s interests and shares of capital stock have been issued in compliance with federal and state securities laws. All such member’s interests and shares of capital stock are owned free and clear of all liens, encumbrances and equities and claims, except for any lien, encumbrance, equity or claim granted or agreed to be granted, in each case as described in the Registration Statement, the General Disclosure Package and the Prospectus (collectively, “Existing Liens”). None of the outstanding member’s interests or shares of capital stock of any of the Wynn Parties was issued in violation of any preemptive rights, rights of first refusal or other similar rights to subscribe for or purchase securities of any such Wynn Party. There are no authorized or outstanding options, warrants, preemptive rights, rights of first refusal or other similar rights to subscribe for or purchase, or equity or debt securities convertible into or exchangeable or exercisable for, any member’s interests or shares of capital stock of any of the Wynn Parties other than those described in all material respects in the Registration Statement, the General Disclosure Package and the Prospectus. The Shares to be issued by the Company pursuant to this Agreement have been duly authorized by all necessary corporate action, and such Shares, when issued, will be validly issued, fully paid and non-assessable; and, except as set

3

forth in the Registration Statement, the General Disclosure Package and the Prospectus, no preemptive rights, rights of first refusal or other similar rights of stockholders or others exist with respect to any of the Shares or the issue and sale thereof by the Company. Neither the filing of the Registration Statement nor the Offering or sale of the Shares contemplated by this Agreement gives rise to any rights, other than those which have been waived or satisfied, for or relating to the registration of any shares of Common Stock. The Common Stock conforms in all material respects to the description thereof contained in the Registration Statement. The form of certificate for the shares of Common Stock conforms to the form required by the corporate law of the state of Nevada.

(e) All of the Shares conform to the description thereof contained in the Registration Statement, the General Disclosure Package and the Prospectus.

(f) The execution and delivery of, and the performance by the Company of its obligations under, this Agreement have been duly and validly authorized by all necessary corporate action on the part of the Company, and this Agreement has been duly executed and delivered by the Company.

(g) The Commission has not issued an order preventing or suspending the use of any Preliminary Prospectus, any Issuer Free Writing Prospectus or the Prospectus relating to the proposed offering of the Shares, and no proceeding for that purpose or pursuant to Section 8A of the Act has been instituted or, to the Company’s knowledge, threatened by the Commission. The Registration Statement contains, and the Prospectus and any amendments or supplements thereto will contain, all statements which are required to be stated therein by, and will conform to, the requirements of the Act and the Rules and Regulations. The documents incorporated, or to be incorporated, by reference in the Prospectus, at the time filed with the Commission conformed or will conform, in all respects to the requirements of the Securities Exchange Act of 1934 (the “Exchange Act”) or the Act, as applicable, and the rules and regulations of the Commission thereunder. The Registration Statement and any amendment thereto do not contain, and will not contain, any untrue statement of a material fact and do not omit, and will not omit, to state a material fact required to be stated therein or necessary to make the statements therein not misleading. The Prospectus and any amendments and supplements thereto do not contain, and will not contain, any untrue statement of a material fact; and do not omit, and will 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; provided, however, that the Company makes no representations or warranties as to information contained in or omitted from the Registration Statement or the Prospectus, or any such amendment or supplement, in reliance upon, and in conformity with, written information furnished to the Company by or on behalf of the Underwriters through the Representatives, specifically for use therein, it being understood and agreed that the only such information is that described in Section 13 herein.

(h) Each Issuer Free Writing Prospectus, as of its issue date and at all subsequent times through the completion of the public offer and sale of the Shares or until any earlier date that the Company notified or notifies the Underwriters as described in the next sentence, did not, does not and will not include any information that conflicted, conflicts or will conflict with the information contained in the Registration Statement or the Prospectus, including any document incorporated by reference and any Prospectus Supplement deemed to be a part thereof that has not been superseded or modified. If at any time following issuance of an Issuer Free Writing Prospectus there occurs an event or development as a result of which such Issuer Free Writing Prospectus conflicts with the information contained in the Registration Statement or contains any untrue statement of a material fact or omits 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, (A) the Company will promptly notify the Underwriters and (B) the Company will promptly amend or supplement such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission. The foregoing two sentences do not apply to statements in or omissions from any Issuer Free Writing Prospectus made in reliance upon and in conformity with written information furnished to the Company by or on behalf of the Underwriters through the Representatives, specifically for use therein, it being understood and agreed that the only such information is that described in Section 13 herein.

None of the Wynn Parties is a party to or bound by any options, licenses or agreements with respect to the Intellectual Property of any other person or entity that are required to be set forth in the Registration Statement, the General Disclosure Package and the Prospectus and are not described therein in all material respects.

(w) Neither the Company nor, to the knowledge of the Company, any of its affiliates (within the meaning of Rule 144 under the Act) (each, an “Affiliate”), has taken, nor will the Company, or to the knowledge of the Company, any such controlled Affiliate, take, directly or indirectly, any action designed to cause or result in, or which has constituted or which could reasonably be expected to constitute, the stabilization or manipulation of the price of the shares of Common Stock to facilitate the sale or resale of the Shares. The Company acknowledges that the Underwriters may engage in passive market making transactions in the Securities in accordance with Regulation M under the Exchange Act.

(x) None of the Wynn Parties, or to the knowledge of any of the Wynn Parties, any of their Affiliates, has distributed or will distribute, prior to the completion of the Underwriters’ distribution of the Shares, any offering material in connection with the offering and sale of the Shares other than the Registration Statement, the General Disclosure Package and the Prospectus.

(y) None of the Wynn Parties is or, after giving effect to the offering and sale of the Shares contemplated hereunder and the application of the net proceeds from such sale as described in the General Disclosure Package and the Prospectus, will be required to register as an “investment company” within the meaning of such term under the Investment Company Act of 1940, as amended (the “1940 Act”), and the rules and regulations of the Commission thereunder.

(z) To the Company’s knowledge, there are no affiliations or associations between any member of FINRA and any of the Company’s officers, other than as set forth in the Registration Statement, the General Disclosure Package and the Prospectus.

(aa) Each of the Wynn Parties keeps accurate books and records and maintains a system of internal accounting controls sufficient to provide reasonable assurances that (i) transactions are executed in accordance with management’s general or specific authorization, (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with generally accepted accounting principles as applied in the United States and to maintain accountability for assets, (iii) access to assets is permitted only in accordance with management’s general or specific authorization and (iv) the recorded accountability for assets is compared with existing assets at reasonable intervals and appropriate action is taken with respect to any differences.

9

(bb) The chief executive officer and chief financial officer of the Company are responsible for establishing and maintaining disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the rules and regulations of the Commission under the Exchange Act) for the Company and have (i) designed such disclosure controls and procedures, or caused such disclosure controls and procedures to be designed under their supervision, to ensure that material information relating to the Company and its subsidiaries is made known to the chief executive officer and chief financial officer by others within the Company and its subsidiaries, (ii) evaluated the effectiveness of the Company’s disclosure controls and procedures and presented in each annual and quarterly report of the Company (each, a “Report”) their conclusions about the effectiveness of the disclosure controls and procedures as of the end of the period covered by each Report based on such evaluation and (iii) disclosed in each Report any change in the Company’s internal control over financial reporting that occurred during the period covered by such Report that has materially affected, or is reasonably likely to materially affect, the Company’s internal controls over financial reporting. The chief executive officer and chief financial officer of the Company have disclosed, based upon their most recent evaluation of the internal controls over financial reporting, to the Company’s auditors and the Audit Committee of the Company’s Board of Directors (x) all significant deficiencies and material weaknesses in the design or operation of internal controls over financial reporting which are reasonably likely to adversely affect the Company’s ability to record, process, summarize and report financial information, and (y) any fraud, whether or not material, that involves management or other employees who have a significant role in the Company’s internal controls. The Company and its subsidiaries maintain systems of internal control over financial reporting that are effective and the Company is not aware of any material weakness in their internal control over financial reporting.

(cc) Each of the Wynn Parties carries, or is covered by, insurance with insurers of recognized financial responsibility in such amounts, with such deductibles and covering such risks as is commercially reasonable, and as the Wynn Parties deem adequate and prudent for the conduct of their respective businesses and the value of their respective properties and as is customary for companies engaged in similar businesses including, but not limited to, policies covering real and personal property owned or leased by the Wynn Parties against theft, damage, destruction, acts of vandalism and earthquakes. The Wynn Parties have no reason to believe that such insurance coverage cannot be renewed as and when such coverage expires or that similar coverage could not be obtained from similar insurers at a cost that would not reasonably be expected to cause a Material Adverse Change (other than as a result of general market conditions).

(dd) Except for matters which would not reasonably be expected to result in a Material Adverse Change, each of the Wynn Parties is in compliance with all presently applicable provisions of the Employee Retirement Income Security Act of 1974, as amended, including the regulations and published interpretations thereunder (“ERISA”). No “reportable event” (as defined in ERISA) has occurred with respect to any “pension plan” (as defined in ERISA) for which any Wynn Parties would have any liability. None of the Wynn Parties has incurred or expects to incur liability under (i) Title IV of ERISA with respect to termination of, or withdrawal from, any “pension plan” or (ii) Section 412 with respect to unpaid or delinquent contributions or 4971 of the Internal Revenue Code of 1986, as amended, including the regulations and published interpretations thereunder (the “Code”). Except for matters which would not reasonably be expected to result in a Material Adverse Change, each “pension plan” for which any Wynn Party would have any liability that is intended to be qualified under Section 401(a) of the Code is so qualified and nothing has occurred, whether by action or by failure to act, which would cause the loss of such qualification.

(ee) None of the Wynn Parties nor, to the knowledge of the Wynn Parties, any director, officer, agent, employee or affiliate of any of the Wynn Parties is currently the subject of any sanctions imposed or administered by the Office of Foreign Assets Control of the U.S. Treasury Department (collectively, “Sanctions”), or is located, organized or resident in a country or territory that is the subject of Sanctions; and the Wynn Parties will not directly or indirectly use the proceeds of the offering, or lend, contribute or otherwise make available such proceeds to any subsidiary, joint venture partner or other person or entity, for the purpose of financing the activities of any person or entity subject to any Sanctions.

10

(ff) The operations of each of the Wynn Parties are and have been conducted at all times in compliance with applicable financial record keeping and reporting requirements of the Currency and Foreign Transactions Reporting Act of 1970, as amended, applicable money laundering statutes and applicable rules and regulations thereunder (collectively, the “Money Laundering Laws”), and no action, suit or proceeding by or before any court or governmental agency, authority or body or any arbitrator involving any of the Wynn Parties with respect to the Money Laundering Laws is pending or, to the knowledge of the Wynn Parties, threatened.

(gg) Except as otherwise disclosed in the Registration Statement, the General Disclosure Package and the Prospectus, none of the Wynn Parties or, to the best knowledge of the Wynn Parties, any director, officer, agent, employee or other person associated with or acting on behalf of any of the Wynn Parties or any owner of 10 percent or more of the capital stock of any of the Wynn Parties has, with respect to any of the Wynn Parties, (i) used any Wynn Parties’ funds for any unlawful contribution, gift, entertainment or other unlawful expense relating to political activity, (ii) made any unlawful payment to any foreign or domestic government official or employee from corporate funds, (iii) violated or is in violation of any provision of the U.S. Foreign Corrupt Practices Act of 1977, as amended, or (iv) made any bribe, unlawful rebate, payoff, influence payment, kickback or other unlawful payment.

(hh) The Company is subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act and files reports with the Commission on the EDGAR System. The Company’s Common Stock is registered pursuant to Section 12(b) of the Exchange Act and the outstanding shares of the Company’s Common Stock are listed on the Nasdaq Global Select Market and the Company has taken no action designed to, or likely to have the effect of, terminating the registration of its Common Stock under the Exchange Act or de-listing the Common Stock from the Nasdaq Global Select Market, nor has the Company received any notification that the Commission or the Nasdaq Global Select Market is contemplating terminating such registration or listing.

(ii) No relationship, direct or indirect, exists between or among any of the Wynn Parties or their subsidiaries, on the one hand, and any manager, member, managing member, director, officer, stockholder, affiliate, customer or supplier of any of them, on the other hand, which would be required by the Act or by the Rules and Regulations promulgated pursuant thereto to be disclosed in a registration statement on Form S-3 which is not so disclosed in the Registration Statement, the General Disclosure Package and the Prospectus.

(jj) Except as disclosed in the Registration Statement, the General Disclosure Package and the Prospectus, there are no holders of securities (debt or equity) of the Wynn Parties, or holders of rights (including, without limitation, preemptive rights), warrants or options to obtain securities of the Wynn Parties, who in connection with the issuance, sale and delivery of the Shares and the execution, delivery and performance of this Agreement, have the right to request the Wynn Parties to register securities held by them under the Act, except for any such rights that have either been fully complied with by the Company or effectively waived by the holders thereof, and any such waivers remain in full force and effect.

(kk) Except as disclosed in the Registration Statement, the General Disclosure Package and the Prospectus, there are no contracts, agreements or understandings between the Company (or any Significant Subsidiary) and any person that would give rise to a valid claim against the Company, any Significant Subsidiary or you for a brokerage commission, finder’s fee or other like payment in connection with the transactions contemplated by this Agreement, General Disclosure Package and the Prospectus or, to the Company’s or any Significant Subsidiary’s knowledge, any arrangements, agreements, understandings, payments or issuance with respect to the Company or any Significant Subsidiary or any of their respective officers, directors, shareholders, partners, employees, subsidiaries or affiliates that may affect your compensation as determined by FINRA.

(ll) (i) There has been no security breach or other compromise of or relating to any of the Wynn Parties or any of their subsidiaries’ information technology and computer systems, networks, hardware, software, data (including the data of their respective customers, employees, suppliers, vendors and any third party data maintained by or on behalf of them), equipment or technology (collectively, “IT Systems”) nor have they been notified of, and have no knowledge of any event or condition that would reasonably be expected to result in, any security breach or other compromise to their IT Systems and (ii) the Wynn Parties and their subsidiaries are presently in compliance with all applicable laws or statutes and all judgments, orders, rules and regulations of any court or arbitrator or governmental or regulatory authority, internal policies and contractual obligations

11

relating to the privacy and security of IT Systems and to the protection of such IT Systems from unauthorized use, access, misappropriation or modification, except, in the case of clause (i) or (ii), as would not, individually or in the aggregate, reasonably be expected to result in a Material Adverse Change.

Any certificate required hereunder signed by or on behalf of the Company and delivered to the Underwriters or to counsel for the Underwriters shall be deemed to be a representation and warranty by the Company to the Underwriters as to the matters covered thereby (and is subject to the limitations set forth therein, if any).

The Company acknowledges that the Underwriters and, for purposes of the opinions to be delivered pursuant to Section 6 hereof, counsel to the Company and counsel to the Underwriters, will rely upon the accuracy and truthfulness of the foregoing representations and hereby consent to such reliance.

2. PURCHASE, SALE AND DELIVERY OF THE SHARES.

(a) On the basis of the representations, warranties and covenants herein contained, and subject to the conditions herein set forth, the Company agrees to sell to the Underwriters and each Underwriter agrees, severally and not jointly, to purchase, at a price of $112.70 per share, the number of Firm Shares set forth opposite the name of each Underwriter in Schedule I hereof, subject to adjustments in accordance with Section 9 hereof.

(b) Payment for the Firm Shares to be sold hereunder is to be made in Federal (same day) funds to an account designated by the Company. Delivery of the Firm Shares shall be made through the facilities of The Depository Trust Company (“DTC”) in New York, in accordance with the instructions from the Underwriters. Certificates for the Shares shall be registered in such names and in such denominations as the Underwriters may request not less than two Business Days in advance of the Closing Date. The Company will cause the certificates, if any, representing the Shares to be made available for inspection, checking and packaging by the Underwriters at the office of DTC or its designated custodian not later than 1:00 p.m. on the Business Day prior to the Closing Date. Such payment and delivery shall be at 10:00 a.m., New York time, on February 11, 2021 or at such other time, not later than five business days thereafter, as you and the Company shall agree upon, such time and date being herein referred to as the “Closing Date.” As used herein, “business day” means a day on which the New York Stock Exchange is open for trading and on which banks in New York are open for business and are not permitted by law or executive order to be closed.

(c) In addition, subject to the representations and warranties herein contained and the terms and conditions herein set forth, the Company hereby grants an option to the several Underwriters to purchase, severally and not jointly, the Option Shares at the price per share as set forth in the first paragraph of this Section 2. The option granted hereby may be exercised at any time and from time to time within 30 days from the date of this Agreement, upon written notice by you, as Representatives of the several Underwriters, to the Company setting forth the number of Option Shares as to which the several Underwriters are exercising the option and the time and date at which such Option Shares are to be delivered. The time and date at which Option Shares are to be electronically delivered shall be determined by the Representatives but shall not be earlier than two nor later than 10 full business days after the exercise of such option, nor in any event prior to the Closing Date (such time and date being herein referred to as the “Option Closing Date”). You may cancel such option at any time prior to its expiration by giving written notice of such cancellation to the Company. To the extent, if any, that the option is exercised, payment for the Option Shares shall be made on the Option Closing Date in Federal (same day) funds to an account designated by the Company against electronic delivery thereof of the Option Shares to the accounts of the Underwriters through the facilities of DTC in New York, New York, in accordance with the instructions from the Underwriters.

Furthermore, notwithstanding the foregoing, upon mutual agreement of the Company and the Underwriters, the settlement and payment of the Shares may be accomplished through other customary delivery methods.

3. OFFERING BY THE UNDERWRITERS.

(a) It is understood that the several Underwriters are to make a public offering of the Firm Shares as soon as the Representatives deem it advisable to do so. The Firm Shares are to be initially offered to the public at the public offering price set forth in the Prospectus. The Representatives may from time to time thereafter change the public offering price and other selling terms. To the extent, if at all, that any Option Shares are purchased pursuant to Section 2 hereof, the Underwriters will offer them to the public on the foregoing terms.

(b) It is further understood that you will act as the Representatives for the Underwriters in the offering and sale of the Shares in accordance with a Master Agreement Among Underwriters entered into by you and the several other Underwriters.

4. COVENANTS OF THE COMPANY.

The Company covenants and agrees with the Underwriters that:

(a) The Company will (A) prepare and timely file with the Commission under Rule 424(b) (without reliance on Rule 424(b)(8)) under the Act a Prospectus in a form approved by the Representatives containing information previously omitted at the time of effectiveness of the Registration Statement in reliance on Rules 430A, 430B or 430C under the Act, (B) not file any amendment to the Registration Statement or distribute an amendment or supplement to the General Disclosure Package or the Prospectus or document incorporated by reference therein of which the Representatives shall not previously have been advised and furnished with a copy or to which the Representatives shall have reasonably objected in writing or which is not in compliance with the Rules and Regulations and (C) file on a timely basis all reports and any definitive proxy or information statements required to be filed by the Company with the Commission subsequent to the date of the Prospectus and prior to the termination of the offering of the Shares by the Underwriters.

(b) The Company will (i) not make any offer relating to the Shares that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405 under the Act) required to be filed by the Company with the Commission under Rule 433 under the Act unless the Representatives approve its use in writing prior to first use (each, a “Permitted Free Writing Prospectus”); provided that the prior written consent of the Representatives shall be deemed to have been given in respect of the Issuer Free Writing Prospectus(es) included in Schedule II hereto, (ii) treat each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus, (iii) comply with the requirements of Rules 163, 164 and 433 under the Act applicable to any Issuer Free Writing Prospectus, including the requirements relating to timely filing with the Commission, legending and record keeping and (iv) not take any action that would result in an Underwriter or the Company being required to file with the Commission pursuant to Rule 433(d) under the Act a free writing prospectus prepared by or on behalf of such Underwriter that such Underwriter otherwise would not have been required to file thereunder.

(c) The Company will advise the Representatives promptly (A) when any post-effective amendment to the Registration Statement or new registration statement relating to the Shares shall have become effective, or any supplement to the Prospectus shall have been filed, (B) of the receipt of any comments from the Commission, (C) of any request of the Commission for amendment of the Registration Statement or the filing of a new registration statement or any amendment or supplement to the General Disclosure Package or the Prospectus or any document incorporated by reference therein or otherwise deemed to be a part thereof or for any additional information, and (D) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or such new registration statement or any order preventing or suspending the use of any Preliminary Prospectus, any Issuer Free Writing Prospectus or the Prospectus, or of the institution of any proceedings for that purpose or pursuant to Section 8A of the Act. The Company will use its best efforts to prevent the issuance of any such order and to obtain as soon as possible the lifting thereof, if issued.

13

(d) If, at any time after the Representatives have informed the Company that Shares remain unsold, the Company receives from the Commission a notice pursuant to Rule 401(g)(2) under the Act or otherwise ceases to be eligible to use the automatic shelf registration statement form, the Company will (i) promptly notify the Representatives, (ii) promptly file a new registration statement or post-effective amendment on the proper form relating to the Shares, in a form satisfactory to the Representatives, (iii) use its best efforts to cause such registration statement or post-effective amendment to be declared effective as soon as practicable (if such filing is not otherwise effective immediately pursuant to Rule 462 under the Act), and (iv) promptly notify the Representatives of such effectiveness. The Company will take all other action necessary or appropriate to permit the public offering and sale of the Shares to continue as contemplated in the Registration Statement that was the subject of the notice under Rule 401(g)(2) under the Act or for which the Company has otherwise become ineligible. References herein to the Registration Statement relating to the Shares shall include such new registration statement or post-effective amendment, as the case may be.

(e) If immediately prior to the third anniversary (the “Renewal Deadline”) of the initial effective date of the Registration Statement the Representatives have informed the Company that Shares remain unsold, the Company will, prior to the Renewal Deadline file, if it has not already done so and is eligible to do so, a new automatic shelf registration statement relating to the Shares, in a form satisfactory to the Representatives. If the Company is no longer eligible to file an automatic shelf registration statement, the Company will, prior to the Renewal Deadline, if it has not already done so, file a new shelf registration statement relating to the Shares, in a form satisfactory to the Representatives, and will use its best efforts to cause such registration statement to be declared effective within 180 days after the Renewal Deadline. The Company will take all other action necessary or appropriate to permit the public offering and sale of the Shares to continue as contemplated in the expired registration statement. References herein to the Registration Statement shall include such new automatic shelf registration statement or such new shelf registration statement, as the case may be.

(f) The Company agrees to pay the required filing fees to the Commission relating to the Shares within the time required by Rule 456(b)(1) under the Act without regard to the proviso therein and otherwise in accordance with Rules 456(b) and 457(r) under the Act.

(g) The Company will cooperate with the Representatives in endeavoring to qualify the Shares for sale under (or obtain exemptions from the application of the qualification requirements of) the securities laws of such jurisdictions as the Representatives may reasonably have designated in writing and will make such applications, file such documents, and furnish such information as may be reasonably required for that purpose, provided the Company shall not be required to qualify as a foreign corporation or to file a general consent to service of process in any jurisdiction where it is not now so qualified or required to file such a consent. The Company will, from time to time, prepare and file such statements, reports, and other documents, as are or may be required to continue such qualifications in effect for so long a period as the Representatives may reasonably request for distribution of the Shares. The Company shall advise the Representatives promptly of the suspension of the qualification or registration of (or any such exemption relating to) the Shares for offering, sale or trading in any jurisdiction or any initiation of threat of any proceeding for any such purpose, and in the event of the issuance of any order suspending such qualification, registration or exemption, the Company shall use its best efforts to obtain the withdrawal thereof at the earliest possible moment.

(h) The Company will deliver to, or upon the order of, the Representatives, from time to time, as many copies of any Preliminary Prospectus or any Issuer Free Writing Prospectus as the Representatives may reasonably request. The Company will deliver to, or upon the order of, the Representatives during the period when delivery of a Prospectus (or, in lieu thereof, the notice referred to under Rule 173(a) under the Act) (the “Prospectus Delivery Period”) is required under the Act, as many copies of the Prospectus in final form, or as thereafter amended or supplemented, as the Representatives may reasonably request. The Company will maintain in the Company’s files manually signed copies of the Registration Statement as initially filed and all amendments thereto including all consents and exhibits filed therewith in accordance with the Rules and Regulations of the Commission.

14

(i) The Company will comply with the Act, the Exchange Act and the rules and regulations of the Commission thereunder, so as to permit the completion of the distribution of the Shares as contemplated in this Agreement and the Prospectus. If during the period in which a prospectus (or, in lieu thereof, the notice referred to under Rule 173(a) under the Act) is required by law to be delivered by an Underwriter or a dealer, any event shall occur as a result of which, in the judgment of the Company or in the reasonable opinion of the Representatives, it becomes necessary to amend or supplement the Prospectus in order to make the statements therein, in the light of the circumstances existing at the time the Prospectus is delivered to a purchaser, not misleading, or, if it is necessary at any time prior to the consummation of the Offering to amend or supplement the Prospectus to comply with any law, the Company promptly will either (i) prepare and file with the Commission an appropriate amendment to the Registration Statement or supplement to the Prospectus or (ii) prepare and file with the Commission an appropriate filing under the Exchange Act which shall be incorporated by reference in the Prospectus so that the Prospectus as so amended or supplemented will not, in the light of the circumstances when it is so delivered, be misleading, or so that the Prospectus will comply with the law.

(j) If the General Disclosure Package is being used to solicit offers to buy the Shares at a time when the Prospectus is not yet available to prospective purchasers and any event shall occur as a result of which, in the judgment of the Company or in the reasonable opinion of the Representatives, it becomes necessary to amend or supplement the General Disclosure Package in order to make the statements therein, in the light of the circumstances, not misleading, or to make the statements therein not conflict with the information contained in the Registration Statement then on file, or if it is necessary at any time to amend or supplement the General Disclosure Package to comply with any law, the Company promptly will either (i) prepare, file with the Commission (if required) and furnish to the Underwriters and any dealers an appropriate amendment or supplement to the General Disclosure Package or (ii) prepare and file with the Commission an appropriate filing under the Exchange Act which shall be incorporated by reference in the General Disclosure Package so that the General Disclosure Package as so amended or supplemented will not, in the light of the circumstances, be misleading or conflict with the Registration Statement then on file, or so that the General Disclosure Package will comply with law.

(k) The Company will make generally available to its security holders, as soon as it is practicable to do so, but in any event not later than 15 months after the effective date of the Registration Statement (as defined in Rule 158(c) under the Act), an earnings statement (which need not be audited) in reasonable detail, complying with the requirements of Section 11(a) of the Act and Rule 158 under the Act and will advise you in writing when such statement has been so made available.

(l) Prior to the Closing Date, the Company will furnish to the Underwriters, as soon as they have been prepared by or are available to the Company, a copy of any unaudited interim financial statements of the Company for any period subsequent to the period covered by the most recent financial statements appearing in the Registration Statement and the Prospectus.

(m) During the period from the date hereof through and including the date that is 45 days after the date of the Prospectus, the Company will not (i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, or submit to, or file with, the Commission a registration statement under the Securities Act relating to, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for shares of Common Stock, or publicly disclose the intention to undertake any of the foregoing, or (ii) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Stock or any such other securities, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Stock or such other securities, in cash or otherwise, without the prior written consent of the Representatives, other than the Shares to be sold hereunder. The restrictions described above do not apply to (i) the issuance of shares of Common Stock or securities convertible into or exercisable for shares of Common Stock pursuant to the conversion or exchange of convertible or exchangeable securities or the exercise of warrants or options (including net exercise) or the settlement of restricted stock units (including net settlement), in each case outstanding on the date of this Agreement and described in the Prospectus; (ii) grants of stock options, stock awards, restricted stock,

15

restricted stock units, or other equity awards and the issuance of shares of Common Stock or securities convertible into or exercisable or exchangeable for shares of Common Stock (whether upon the exercise of stock options or otherwise) to the Company’s employees, officers, directors, advisors, or consultants pursuant to the terms of an equity compensation plan in effect as of the Closing Date and described in the Prospectus, provided that such recipients enter into a lock-up agreement with the Underwriters; or (iii) the filing of any registration statement on Form S-8, or any amendments thereto, relating to securities granted or to be granted pursuant to any plan in effect on the date of this Agreement and described in the Prospectus or any assumed benefit plan pursuant to an acquisition or similar strategic transaction.

(n) The Company will use its best efforts to list, subject to notice of issuance, the Shares on the Nasdaq Global Select Market.

(q) The Company will maintain a transfer agent and, if necessary under the jurisdiction of incorporation of the Company, a registrar for the Common Stock.

(r) The Company will not take, directly or indirectly, any action designed to cause or result in, or that has constituted or might reasonably be expected to constitute, the stabilization or manipulation of the price of any securities of the Company.

5. COSTS AND EXPENSES.

The Company will pay all costs, expenses and fees incident to the performance of the obligations of the Company under this Agreement, including, without limiting the generality of the foregoing, the following: (i) accounting fees of the Company; (ii) the fees and disbursements of counsel for the Company; (iii) the cost of printing and delivering to, or as requested by, the Underwriters copies of the Registration Statement, Preliminary Prospectus, the Issuer Free Writing Prospectuses, the Prospectus, this Agreement, the Listing Application and any supplements or amendments thereto; (iv) the filing fees of the Commission; (v) the filing fees and expenses (excluding legal fees and disbursements of counsel to the Underwriters) incident to securing any required review by FINRA of the terms of the sale of the Shares; (vi) the Listing Fee of the Nasdaq Global Select Market; and (vii) the expenses, excluding fees and disbursements of counsel for the Underwriters, incurred in connection with the qualification of the Shares under State securities or Blue Sky laws, not to exceed $2,500.

6. CONDITIONS OF OBLIGATIONS OF THE UNDERWRITERS.

The several obligations of the Underwriters to purchase the Firm Shares on the Closing Date and the Option Shares, if any, on the Option Closing Date are subject to the accuracy, as of the Applicable Time, the Closing Date or the Option Closing Date, as the case may be, of the representations and warranties of the Company contained herein, and to the performance by the Company of its covenants and obligations hereunder to be performed prior to the Closing Date or the Option Closing Date, as the case may be, and to the following additional conditions:

(iii) All filings required to have been made pursuant to Rules 424(b), 430A, 430B or 430C under the Act have been made as and when required by such rules;

8. INDEMNIFICATION.

(a) The Company agrees to indemnify and hold harmless each Underwriter, its Affiliates and each person, if any, who controls or is controlled by any Underwriter within the meaning of either Section 15 of the Act or Section 20 of the Exchange Act, against any losses, claims, damages or liabilities to which such Underwriter or any such controlling person may become subject under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, any Preliminary Prospectus, any Issuer Free Writing Prospectus, the Prospectus or any amendment or supplement thereto, (ii) with respect to the Registration Statement or any amendment or supplement thereto, the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or (iii) with respect to any Preliminary Prospectus, any Issuer Free Writing Prospectus, the Prospectus or any amendment or supplement thereto, the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances under which they were made or (iv) any act or failure to act, or any alleged act or failure to act by any Underwriter in connection with, or relating in any manner to, the Shares 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), (ii) or (iii) above (provided, that the Company shall not be liable under this clause (iv) 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 Underwriter through its gross negligence or willful misconduct); provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement, or omission or alleged omission made in the Registration Statement, any Preliminary Prospectus, any Issuer Free Writing Prospectus, the Prospectus, or such amendment or supplement, in reliance upon and in conformity with written information furnished to the Company by or through the Representatives specifically for use in the preparation thereof, which information is limited to that set forth in Section 13. The Company also agrees to reimburse each Underwriter, its Affiliates and each such controlling person upon demand for any legal or other out-of-pocket expenses reasonably incurred by such Underwriter or such controlling person in connection with investigating or defending any such loss, claim, damage or liability, action or proceeding or in responding to a subpoena or governmental inquiry related to the Offering of the Shares, whether or not such Underwriter or controlling person is a party to any action or proceeding. In the event that it is finally judicially determined that the Underwriters were not entitled to receive payments for legal and other expenses pursuant to this subparagraph, the Underwriters will promptly return all sums that had been advanced pursuant hereto.

(b) Each Underwriter severally and not jointly will indemnify and hold harmless the Company, each of its directors, each of its officers who have signed the Registration Statement, and each person, if any, who controls the Company within the meaning of the Act, against any losses, claims, damages or liabilities to which the Company or any such director, officer, or controlling person may become subject under the Act or

19

otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, any Preliminary Prospectus, any Issuer Free Writing Prospectus, the Prospectus or any amendment or supplement thereto or the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or ii) with respect to the Registration Statement or any amendment or supplement thereto, the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading or (iii) with respect to any Preliminary Prospectus, any Issuer Free Writing Prospectus, the Prospectus or any amendment or supplement thereto, the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances under which they were made; and will reimburse any legal or other expenses reasonably incurred by the Company or any such director, officer or controlling person in connection with investigating or defending any such loss, claim, damage, liability, action or proceeding; provided, however, that each Underwriter will be liable in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission has been made in the Registration Statement, any Preliminary Prospectus, any Issuer Free Writing Prospectus, the Prospectus or such amendment or supplement, in reliance upon and in conformity with written information furnished to the Company by or through the Representatives specifically for use thereof, which information is limited to that set forth in Section 13. This indemnity agreement will be in addition to any liability which such Underwriter may otherwise have.

(c) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to this Section 8, such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing. No indemnification provided for in Section 8(a) or (b) shall be available to any party who shall fail to give notice as provided in this Section 8(c) if the party to whom notice was not given was unaware of the proceeding to which such notice would have related and was materially prejudiced by the failure to give such notice, but the failure to give such notice shall not relieve the indemnifying party or parties from any liability which it or they may have to the indemnified party for contribution or otherwise than on account of the provisions of Section 8(a) or (b). In case any such proceeding shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party and shall pay as incurred the reasonable fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel at its own expense. Notwithstanding the foregoing, the indemnifying party shall pay as incurred (or within 30 days of presentation) the reasonable fees and expenses of the counsel retained by the indemnified party in the event (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel, (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them or (iii) the indemnifying party shall have failed to assume the defense and employ counsel reasonably acceptable to the indemnified party within a reasonable period of time after notice of commencement of the action. It is understood that the indemnifying party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees and expenses of more than one separate firm for all such indemnified parties. Such firm shall be designated in writing by you in the case of parties indemnified pursuant to Section 8(a) and by the Company in the case of parties indemnified pursuant to Section 8(b). The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. In addition, the indemnifying party will not, without the prior written consent of the indemnified party, settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action or proceeding of which indemnification may be sought hereunder (whether or not any indemnified party is an actual or potential party to such claim, action or proceeding) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action or proceeding.

20

(d) To the extent the indemnification provided for in this Section 8 is unavailable to or insufficient to hold harmless an indemnified party under Section 8(a) or (b) above in respect of any losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other from the Offering of the Shares. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions or proceedings in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the Offering (before deducting expenses) received by the Company bear to the total underwriting discounts, commissions and fees received by the Underwriters, in each case as set forth on the cover page of the Prospectus. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or the Underwriters on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section 8(d) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 8(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to above in this Section 8(d) shall be deemed to include 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 subsection (d), (i) no Underwriter shall be required to contribute any amount in excess of the underwriting discounts, commissions and fees applicable to the Shares purchased by such Underwriter and (ii) 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 Underwriters’ obligations in this Section 8(d) to contribute are several in proportion to their respective underwriting obligations and not joint.

(e) In any proceeding relating to the Registration Statement, any Preliminary Prospectus, any Issuer Free Writing Prospectus, the Prospectus or any supplement or amendment thereto, each party against whom contribution may be sought under this Section 8 hereby consents to the jurisdiction of any state or federal court in the City and County of New York, Borough of Manhattan, agrees that process issuing from such court may be served upon it by any other contributing party and consents to the service of such process and agrees that any other contributing party may join it as an additional defendant in any such proceeding in which such other contributing party is a party.

(f) Any losses, claims, damages, liabilities or expenses for which an indemnified party is entitled to indemnification or contribution under this Section 8 shall be paid by the indemnifying party to the indemnified party as such losses, claims, damages, liabilities or expenses are incurred. The indemnity and contribution agreements contained in this Section 8 and the representations and warranties of the Company set forth in this Agreement shall remain operative and in full force and effect, regardless of (i) any investigation made by or on behalf of any Underwriter, its Affiliates or any person controlling any Underwriter, the Company, its directors or officers or any persons controlling the Company, (ii) acceptance of any Shares and payment therefor hereunder, and (iii) any termination of this Agreement. A successor to any Underwriter, its Affiliates or any person controlling any Underwriter, or to the Company, its directors or officers, or any person controlling the Company, shall be entitled to the benefits of the indemnity, contribution and reimbursement agreements contained in this Section 8.

21

9. DEFAULT BY UNDERWRITERS.

If on the Closing Date or the Option Closing Date, as the case may be, any Underwriter shall fail to purchase and pay for the portion of the Shares which such Underwriter has agreed to purchase and pay for on such date (otherwise than by reason of any default on the part of the Company), you as Representatives of the Underwriters, shall use your reasonable efforts to procure within 36 hours thereafter one or more other underwriters, to purchase from the Company such amounts as may be agreed upon and upon the terms set forth herein, the Shares which the defaulting Underwriter failed to purchase. If during such 36 hours you, as such Representatives, shall not have procured such other underwriters to purchase the Shares agreed to be purchased by the defaulting Underwriter, then (a) if the aggregate number of Shares with respect to which such default shall occur does not exceed 10% of the Shares to be purchased on the Closing Date or the Option Closing date, as the case may be, the non-defaulting Underwriters shall be obligated to purchase the Shares which such defaulting Underwriter failed to purchase, or (b) if the aggregate number of Shares with respect to which such default shall occur exceeds 10% of the Shares to be purchased on the Closing Date or the Option Closing Date, as the case may be, the Company or you, as the Representatives of the Underwriters, will have the right, by written notice given within the next 36-hour period to the parties to this Agreement, to terminate this Agreement without liability on the part of the non-defaulting Underwriters or of the Company except to the extent provided in Sections 5 and 8 hereof. In the event of a default by any Underwriter, as set forth in this Section 9, the Closing Date or Option Closing Date, as the case may be, may be postponed for such period, not exceeding seven days, as you, as the Representatives, may determine in order that the required changes in the Registration Statement, the General Disclosure Package or in the Prospectus or in any other documents or arrangements may be effected. The term “Underwriter” includes any person substituted for a defaulting Underwriter. Any action taken under this Section 9 shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

10. NOTICES.

All notices and other communications hereunder shall be in writing and, except as otherwise provided herein, will be mailed, delivered, telecopied or telegraphed and confirmed as follows: (i) if to the Underwriters, to the Representatives at c/o Deutsche Bank Securities Inc., 60 Wall Street, New York, New York 10005; Attention: Equity Capital Markets – Syndicate Desk, with a copy to Attention: General Counsel, 36th Floor, fax: (646) 374-1071, c/o Goldman Sachs & Co.

22

of trading of the Company’s Common Stock by the Nasdaq Global Select Market, the Commission, or any other governmental authority or, (viii) the taking of any action by any governmental body or agency in respect of its monetary or fiscal affairs which in your reasonable opinion has a material adverse effect on the securities markets in the United States; or (b) as provided in Section 6 of this Agreement.

12. SUCCESSORS.

This Agreement has been and is made solely for the benefit of the Underwriters and the Company and their respective successors, executors, administrators, heirs and assigns, and the officers, directors and controlling persons referred to herein, and no other person will have any right or obligation hereunder. No purchaser of any of the Shares from any Underwriter shall be deemed a successor or assign merely because of such purchase.

13. INFORMATION PROVIDED BY THE UNDERWRITERS.

The Company and the Underwriters acknowledge and agree that the only information furnished or to be furnished by any Underwriter to the Company for inclusion in the Registration Statement, any Preliminary Prospectus, any Issuer Free Writing Prospectus or the Prospectus consists of the information set forth in the eighth paragraph under the caption “Underwriting” in the Prospectus.

14. PARTIAL ENFORCEABILITY.

The invalidity or unenforceability of any Section, paragraph or provision of this Agreement shall not affect the validity or enforceability of any other Section, paragraph or provision hereof. If any Section, paragraph or provision of this Agreement is, for any reason, determined to be invalid or unenforceable, there shall be deemed to be made such minor changes (and only such minor changes) as are necessary to make it valid and enforceable and to effect the original intent of the parties hereto.

15. RECOGNITION OF U.S. SPECIAL RESOLUTION REGIMES.

(a) In the event that any Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

(b) In the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate of such Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.

“BHC Act Affiliate” has the meaning assigned to the term “affiliate” in, and shall be interpreted in accordance with, 12 U.S.C. § 1841(k).

The Company agrees that it will not claim that any Underwriter has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to the Company, in connection with such transaction or the process leading thereto. None of the activities of the Underwriters in connection with the transactions contemplated herein constitutes a recommendation, investment advice, or solicitation of any action by the Underwriters with respect to any entity or natural person.

17. JURISDICTION.

Each party irrevocably agrees that any legal suit, action or proceeding arising out of or based upon this Agreement or the transactions contemplated hereby may be instituted in the federal courts of the United States of America located in the City of New York or the courts of the State of New York in each case located in the Borough of Manhattan in the City of New York (collectively, the “Specified Courts”), and irrevocably submits to the exclusive jurisdiction (except for proceedings instituted in regard to the enforcement of a judgment of any such court, as to which such jurisdiction is non-exclusive) of such courts in any such suit, action or proceeding. The parties further agree that service of any process, summons, notice or document by mail to such party’s address set forth above shall be effective service of process for any lawsuit, action or other proceeding brought in any such court. The parties hereby irrevocably and unconditionally waive any objection to the laying of venue of any lawsuit, action or other proceeding in the Specified Courts, and hereby further irrevocably and unconditionally waive and agree not to plead or claim in any such court that any such lawsuit, action or other proceeding brought in any such court has been brought in an inconvenient forum.

as Representatives of the several Underwriters
