Wynn Resorts, Limited, a Nevada corporation (the “Company”), proposes to sell to Deutsche Bank Securities Inc. (“you” or “DBSI” or the “Underwriter”), an aggregate of 7,500,000 shares (the “Firm Shares”) of the Company’s Common Stock, par value $0.01 per share (the “Common Stock”). The Company also proposes to sell, at the Underwriter’s option, an aggregate of up to 1,125,000 additional shares (the “Option Shares”) of the Company’s Common Stock as set forth below. The Firm Shares and the Option Shares (to the extent the aforementioned option is exercised) are herein collectively called the “Shares.” The offering and sale of the Shares is referred to herein as the “Offering”.

In consideration of the mutual agreements contained herein and of the interests of the parties in the transactions contemplated hereby, the parties hereto agree as follows:

(a) The Company has filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-3 (No. 333-114022), and related prospectuses for the registration under the Securities Act of 1933, as amended (the “Securities Act”), of the Company’s Common Stock and other securities, as described therein, and the offering thereof from time to time in accordance with Rule 415 of the rules and regulations of the Commission (the “Rules and Regulations”) under the Securities Act, which registration statement, as so amended (including post-effective amendments, if any), has been declared effective by the Commission and copies of which have heretofore been delivered or made available to you. The registration statement, as amended at the time it became effective,

including the exhibits and information (if any) deemed to be part of the registration statement at the time of effectiveness pursuant to Rule 430A or 434(d) under the Securities Act, is hereinafter referred to as the “Registration Statement.” If the Company has filed or is required pursuant to the terms hereof to file a registration statement pursuant to Rule 462(b) under the Securities Act increasing the size of the Offering by registering additional shares of Common Stock (a “Rule 462(b) Registration Statement”), then, unless otherwise specified, any reference herein to the term “Registration Statement” shall be deemed to include such Rule 462(b) Registration Statement. Other than a Rule 462(b) Registration Statement, which, if filed, becomes effective upon filing, no other document with respect to the Registration Statement relating to this Offering has heretofore been filed with the Commission. All of the Shares have been registered under the Securities Act pursuant to the Registration Statement or, if any Rule 462(b) Registration Statement is filed, will be duly registered under the Securities Act with the filing of such Rule 462(b) Registration Statement. No stop order suspending the effectiveness of either the Registration Statement or the Rule 462(b) Registration Statement, if any, has been issued and no proceeding for that purpose has been initiated or threatened by the Commission. The Company, if required by the Rules and Regulations of the Commission or by the Securities Act, proposes to file the Prospectus (as defined below) with the Commission pursuant to Rule 424(b) under the Securities Act (“Rule 424(b)”). The base prospectus contained in the Registration Statement, at the time such registration statement was declared effective, as supplemented by the final prospectus supplement relating to the Offering in the form in which it is to be filed with the Commission pursuant to Rule 424(b), is hereinafter referred to as the “Prospectus,” except that if any revised prospectus or prospectus supplement shall be provided to you by the Company for use in connection with the Offering which differs from the Prospectus (whether or not such revised prospectus or prospectus supplement is required to be filed by the Company pursuant to Rule 424(b)), the term “Prospectus” shall also refer to such revised prospectus or prospectus supplement, as the case may be, from and after the time it is first provided to you for such use. Any reference herein to the Registration Statement or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 12 of Form S-3 which were filed under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) on or before the effective date of the Registration Statement or the date of the Prospectus, as the case may be, and any reference herein to the terms “amend”, “amendment” or “supplement” with respect to the Registration Statement or the Prospectus shall be deemed to refer to and include (i) the filing, on or prior to the Closing Date, of any document under the Exchange Act after the effective date of the Registration Statement or the date of the Prospectus, as the case may be, which is incorporated therein by reference and (ii) any such document so filed. All references in this Agreement to the Registration Statement, the Rule 462(b) Registration Statement and the Prospectus, or any amendments or supplements to any of the foregoing shall be deemed to include any copy thereof filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval System (the “EDGAR System”).

(b) At the time of the effectiveness of the Registration Statement or any Rule 462(b) Registration Statement or the effectiveness of any post-effective amendment to the Registration Statement, when the Prospectus is first filed with the Commission pursuant to Rule 424(b) or Rule 434 under the Securities Act (“Rule 434”), when any supplement to or amendment of the Prospectus is filed with the Commission, when any document filed under the Exchange Act (and incorporated by reference) was or is filed and at the Closing Date, the Registration Statement and the Prospectus and any such amendments thereof and supplements thereto contained or will contain all statements which are required to be stated therein and

complied or will comply in all material respects with the applicable provisions of the Securities Act, the Exchange Act and the Rules and Regulations, as applicable. If Rule 434 is used, the Company will comply with the requirements of Rule 434 and the Prospectus shall not be “materially different,” as such term is used in Rule 434, from the Prospectus included in the Registration Statement at the time it became effective. No representation and warranty is made in this subsection (b), however, with respect to any information contained in or omitted from the Registration Statement or the Prospectus or any amendment thereof or supplement thereto in reliance upon and in conformity with information furnished in writing to the Company by the Underwriter specifically for use therein.

(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 and the Prospectus and to enter into and to perform its obligations under this Agreement.

The Company does not own or control, directly or indirectly, any corporation, association or other entity other than the Subsidiaries listed on Exhibit A hereto. The Company and each of the Subsidiaries are duly qualified to transact business in all jurisdictions in which the conduct of their 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 business, properties, assets, operations, condition (financial or otherwise) or prospects of the Company and its Subsidiaries, taken as a whole, whether or not occurring in the ordinary course of business (any such change, a “Material Adverse Change”). The outstanding membership interests and shares of capital stock of each of the Subsidiaries have been duly authorized and validly issued, the shares of capital stock of such Subsidiaries are fully paid and non-assessable and, except as accurately described in all material respects in the Registration Statement or Prospectus or as set forth on Exhibit A, all such interests and shares are owned by the Company or another Subsidiary free and clear of all liens, encumbrances and equities and claims; and except as accurately described in all material respects in the Registration Statement or Prospectus or as set forth on Exhibit A, 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 capital stock of the Company or any of its Subsidiaries.

(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. As of the date hereof, there are 90,531,567 shares of Common Stock and no shares of Preferred Stock outstanding. The outstanding shares of Common Stock of the Company have been duly authorized and validly issued, are fully paid and non-assessable, and have been issued in compliance with federal and state securities laws. None of the outstanding shares of Common Stock of the Company were issued in violation of any preemptive rights, rights of first refusal or other similar rights to subscribe for or purchase securities of the Company. 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 forth in the Registration Statement or 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.

(g) The consolidated financial statements of the Company and its Subsidiaries, together with related notes and schedules as set forth or incorporated by reference in the Registration Statement and the Prospectus (collectively, the “financial statements”), present fairly the consolidated financial position and the results of operations and cash flows of the Company and its Subsidiaries, at the indicated dates and for the indicated periods. Such financial statements have been prepared in accordance with generally accepted principles of accounting as applied in the United States, consistently applied throughout the periods involved, except as disclosed therein, and all adjustments necessary for a fair presentation of results for such periods have been made.

No “reportable event” (as defined in ERISA) has occurred with respect to any “pension plan” (as defined in ERISA) for which the Company or any of its Subsidiaries would have any liability. Neither the Company nor any of its Subsidiaries 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 that would not reasonably be expected to result in a Material Adverse Change, each “pension plan” for which the Company or any Subsidiary 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, that would cause the loss of such qualification.

(bb) The statistical and market-related data included in the Registration Statement and the Prospectus are based on or derived from sources which the Company reasonably and in good faith believes are reliable and accurate, and such data agree with the sources from which they are derived.

(cc) Neither the Company nor any of its Subsidiaries nor, to the best of the Company’s knowledge, any director, officer, agent, employee or other person associated with or acting on behalf of the Company or any of its Subsidiaries or any beneficial owner of 10 percent or more of the capital stock of the Company or any of its Subsidiaries has, with respect to the Company or any of its Subsidiaries, (i) used any corporate 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 Foreign Corrupt Practices Act of 1977, as amended, or (iv) made any bribe, unlawful rebate, payoff, influence payment, kickback or other unlawful payment.

(dd) Based on the knowledge of the chief executive officer and chief financial officer of the Company, (i) the Annual Report on Form 10-K for the year ended December 31, 2003, the Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2004, the Quarterly Report on Form 10-Q for the fiscal quarter ended June 30, 2004, as amended by the Quarterly Report on Form 10-Q/A, and the Quarterly Report on Form 10-Q for the fiscal quarter ended September 30, 2004 (each a “Report”, and together, the “Reports”), fully comply with the requirements of Section 13(a) or 15(d) of the Exchange Act; and (ii) the information contained in each Report fairly presents, in all material respects, the financial condition and results of operations of the Company and its consolidated Subsidiaries as of the date of filing with the Commission.

(ee) The documents incorporated or deemed to be incorporated by reference in the Registration Statement and the Prospectus, at the time they were, or hereafter are, filed with the Commission, complied and will comply in all material respects with the requirements of the Securities Act, the Exchange Act and the Rules and Regulations of the Commission thereunder, and, when read together with the other information set forth in, or incorporated by reference in, the Prospectus, at the time the Registration Statement and any amendments thereto became effective and at the Closing Date (as defined below), do not and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(gg) 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(g) of the Exchange Act and the outstanding shares of the Company’s Common Stock are listed on the Nasdaq National 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 National Market, nor has the Company received any notification that the Commission or the Nasdaq National Market is contemplating terminating such registration or listing.

(hh) The conditions for use of Form S-3, as set forth in the General Instructions thereto, have been satisfied.

(ii) None of the Company, its Affiliates or any person acting on its or any of their behalf (other than the Underwriter, as to whom the Company does not make any representation) has engaged or will engage, in connection with the offering of the offered Shares, in any form of general solicitation or general advertising within the meaning of Rule 502(c) under the Securities Act.

(kk) There are no outstanding subscriptions, rights, warrants, options, calls, convertible securities, commitments for sale or liens related to or entitling any person to purchase or otherwise to acquire any shares of the capital stock of, or other ownership interest in, the Company or any wholly owned subsidiary thereof or with respect to any capital stock or other ownership interest that the Company or any of its Subsidiaries owns in a less than wholly owned subsidiary, except (i) as otherwise disclosed in the Prospectus, or (ii) such as are not material to the business, prospects, financial condition or results of operations of the Company and its Subsidiaries, taken as a whole.

(ll) 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-14 and 15d-14 of the Rules and Regulations under the Exchange Act) for the Company and have (i) designed such disclosure controls and procedures 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 of the Company’s disclosure controls and procedures as of a the end of the period (the “Evaluation Date”) covered by each Report, and (iii) presented in each Report their conclusions about the effectiveness of the disclosure controls and procedures based on their evaluation as of the Evaluation Date. The chief executive officer and chief financial officer of the Company have disclosed, based upon their evaluation as of the Evaluation Date, to the Company’s auditors and the Audit Committee of the Company’s Board of Directors (i) all significant deficiencies in the design or operation of internal controls which could adversely affect the Company’s ability to record, process, summarize and report financial data and have identified for the Company’s auditors any material weaknesses in internal controls, and (ii) any fraud, whether or not material, that involves management or other employees who have a significant role in the registrant’s internal controls. The chief executive officer and chief financial officer have indicated in each Report whether or not there were significant changes in internal controls or in other factors that could significantly affect internal controls subsequent to the Evaluation Date, including any corrective actions with regard to significant deficiencies and material weaknesses.

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

(mm) Except as disclosed in the Registration Statement and the Prospectus, no holder of any Common Stock or other security of the Company or any Subsidiary or any security convertible into, or exercisable or exchangeable for, Common Stock or any other such security (any “Relevant Security”) or debt security has any rights to require registration of any Relevant Security or debt security as part or on account of, or otherwise in connection with, the offer and sale of the

Shares contemplated hereby, and any such rights so disclosed 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.

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

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

(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 Underwriter and the Underwriter agrees to purchase, at a price of $60.43 per share, the Firm Shares.

(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 against electronic delivery thereof of the Firm Shares to the account of the Underwriter through the facilities of The Depository Trust Company (“DTC”) in New York, New York, in accordance with the instructions from the Underwriter. Such payment and delivery are to be made through the facilities of The Depository Trust Company, New York, New York at 10:00 a.m., New York time, on November 15, 2004 or at such other time and date 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, on the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Company hereby grants an option to the Underwriter to purchase 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 in whole or in part by giving written notice (i) at any time before the Closing Date and (ii) only once thereafter within 30 days after the date of this Agreement, to the Company setting forth the number of Option Shares as to which you are exercising the option and the time and date at which such Shares are to be delivered. The time and date at which Option Shares are to be electronically delivered shall be determined by the Underwriter 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”). The option with respect to the Option Shares granted hereunder may be exercised only to cover over-allotments in the sale of the Firm Shares by the Underwriter. 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 account of the Underwriter through the facilities of DTC in New York, New York, in accordance with the instructions from the Underwriter.

It is understood that the Underwriter is to make a public offering of the Firm Shares as soon as the Underwriter deems 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 Underwriter 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 Underwriter will offer them to the public on the foregoing terms.

(a) If Rule 430A is used or the filing of the Prospectus is otherwise required under Rule 424(b) or Rule 434, the Company will file the Prospectus (properly completed if Rule 430A has been used) pursuant to Rule 424(b) within the prescribed time period and will provide evidence satisfactory to DBSI of such timely filing. If the Company elects to rely on Rule 434, the Company will prepare and file a term sheet that complies with the requirements of Rule 434.

(b) Prior to and through the completion of the distribution of the Shares, the Company will notify you promptly (and, if requested by DBSI, will confirm such notice in writing) (i) of any request by the Commission for any amendment of or supplement to the Registration Statement or the Prospectus or for any additional information, (ii) of the Company’s intention to file or prepare any supplement or amendment to the Registration Statement or the Prospectus, (iii) of the mailing or the delivery to the Commission for filing of any amendment of or supplement to the Registration Statement or the Prospectus, including but not limited to Rule 462(b) under the Securities Act, (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or any post-effective amendment thereto or of the initiation, or the threatening, of any proceedings therefor, it being understood that the Company shall make every reasonable effort to avoid the issuance of any such stop order, (v) of the receipt of any comments from the Commission, and (vi) of the receipt by the Company of any notification with respect to the suspension of the qualification of the Shares for sale in any jurisdiction or the initiation or threatening of any proceeding for that purpose. If the Commission shall propose or enter a stop order at any time, the Company will, prior to and through the completion of the distribution of the Shares, make every reasonable effort to prevent the issuance of any such stop order and, if issued, to obtain the lifting of such order as soon as possible. Prior to and through the completion of the distribution of the Shares, the Company will not file any amendment to the Registration Statement or any amendment of or supplement to the Prospectus (including the prospectus required to be filed pursuant to Rule 424(b) or Rule 434) that differs from the prospectus supplement filed with the Commission on November 9, 2004 or file any document under the Exchange Act if such document would be deemed to be incorporated by reference into the Prospectus to which DBSI shall reasonably object in writing after being timely furnished in advance a copy thereof. The Company will provide DBSI with copies of all such amendments, filings and other documents a sufficient time prior to any filing or other publication thereof to permit DBSI a reasonable opportunity to review and comment thereon.

(c) The Company will cooperate with the Underwriter 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 Underwriter 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 Underwriter may reasonably request for distribution of the Shares. The Company shall advise the Underwriter 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.

(d) The Company consents to the use and delivery of the Prospectus by the Underwriter in accordance with Rule 430 and Section 5(b) of the Securities Act.

(e) 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, for at least five years after the date of filing. The Company will promptly deliver to the Underwriter such number of copies of the Prospectus and the Registration Statement, and all amendments of and supplements to such documents, if any, and all documents incorporated by reference in the Registration Statement and Prospectus or any amendment thereof or supplement thereto, as you may reasonably request. Prior to 10:00 A.M., New York City time, on the business day next succeeding the date of this Agreement and from time to time thereafter, the Company will furnish the Underwriter with copies of the Prospectus in such quantities as you may reasonably request.

(f) The Company will comply with the Securities 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 is required by law to be delivered by the Underwriter or dealer, any event shall occur as a result of which, in the judgment of the Company or in the reasonable opinion of the Underwriter, 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 prepare and file with the Commission an appropriate amendment to the Registration Statement or supplement to 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.

(g) 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 date of the Prospectus, an earnings statement (which need not be audited) in reasonable detail, covering a period of at least 12 consecutive months beginning after the date of the Prospectus, which earnings statement shall comply with the requirements of Section 11(a) of the Securities Act and Rule 158 of the Rules and Regulations, and will advise you in writing when such statement has been so made available.

(h) Prior to the Closing Date, the Company will furnish to the Underwriter, 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.

(i) No offering, sale, short sale or other disposition of any shares of Common Stock of the Company or other securities convertible into or exchangeable or exercisable for shares of Common Stock or derivative of Common Stock (or agreement for such) will be made for a period of 60 days after the date of this Agreement, directly or indirectly, by the Company otherwise than hereunder or without the prior written consent of DBSI, which consent shall not be unreasonably withheld; provided, however, that the Company may issue (i) shares of its Common Stock upon the exercise of options, (ii) shares of its Common Stock pursuant to stock grants and (iii) options to purchase its Common Stock, to directors, officers and employees of the Company, issued pursuant to employee or director benefit plans, stock option plans or the employee compensation plans.

(j) The Company, during the period when the Prospectus is required to be delivered under the Securities Act or the Exchange Act, will file all documents required to be filed with the Commission pursuant to the Securities Act, the Exchange Act and the Rules and Regulations within the time periods required thereby (including any extensions permitted by the Rules and Regulations thereunder).

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

(l) The Company will use its best efforts to cause each executive officer, director, other person or entity listed on Exhibit B to furnish to you, on or prior to the Closing Date, a letter or letters substantially in the form of Exhibit C hereto (the “Lockup Agreements”).

(m) The Company will use its best efforts to cause each executive officer, director and 5% or greater stockholder of the Company’s Common Stock, to provide such information to counsel for the Underwriter as is necessary for it to submit information regarding this transaction to the NASD for review under NASD Rule 2710.

(n) The Company shall apply the net proceeds of its sale of the Shares as set forth in the Prospectus and shall file such reports with the Commission with respect to the sale of the Shares and the application of the proceeds therefrom as may be required in accordance with Rule 463 under the Act.

(o) The Company shall not invest, or otherwise use the proceeds received by the Company from its sale of the Shares in such a manner as would require the Company or any of the Subsidiaries to register as an investment company under the 1940 Act.

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

(q) 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.

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 Underwriter copies of the Registration Statement, the Prospectus, this Agreement, the Listing Application, the Blue Sky Survey and any supplements or amendments thereto; (iv) the filing fees of the Commission; (v) the filing fees and expenses (including reasonable and documented legal fees and disbursements of counsel to the Underwriter, not to exceed $15,000) incident to securing any required review by the NASD of the terms of the sale of the Shares; (vi) the Listing Fee of the Nasdaq National Market; and (vii) the expenses, including the reasonable and documented fees and disbursements of counsel for the Underwriter, incurred in connection with the qualification of the Shares under State securities or Blue Sky laws. The Company shall not, however, be required to pay for the Underwriter’s costs and expenses (other than those as described in clauses (v) and (vii) above), including, without limitation, (a) the fees and expenses of counsel to the Underwriter (other than as set forth above), (b) the “roadshow” expenses of the Underwriter and (c) the advertising expenses of the Underwriter incurred in connection with the Offering; provided, however, if the sale of Shares pursuant to Section 2 of this Agreement shall not be consummated because the conditions in Section 6 hereof (other than Section 6(k)) are not satisfied, or because this Agreement is terminated by the Underwriter pursuant to Section 10(a) hereof, or by reason of any failure, refusal or inability on the part of the Company to perform any undertaking or satisfy any condition of this Agreement or to comply with any of the terms hereof on its part to be performed, unless such failure, refusal or inability is due primarily to the default or omission of the Underwriter, the Company shall reimburse the Underwriter for reasonable out-of-pocket expenses, including reasonable and documented fees and disbursements of counsel, reasonably incurred in connection with investigating, marketing and proposing to market the Shares or in contemplation of performing their obligations hereunder; but the Company shall not in any event be liable to the Underwriter for damages on account of loss of anticipated profits from the sale by them of the Shares.

The obligation of the Underwriter to purchase the Firm Shares on the Closing Date and the Option Shares, if any, on the Option Closing Date is subject to the accuracy, as of 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

The Company also agrees to reimburse the Underwriter and each such controlling person upon demand for any legal or other out-of-pocket expenses reasonably incurred by the 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 the Underwriter or controlling person is a party to any action or proceeding. In the event that it is finally judicially determined that the Underwriter was not entitled to receive payments for legal and other expenses pursuant to this subparagraph, the Underwriter will promptly return all sums that had been advanced pursuant hereto.

(b) The Underwriter 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 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 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) any untrue statement or alleged untrue statement of any material fact contained in the Prospectus or any

amendment or supplement thereto, or the omission or the 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 the 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, the Prospectus or such amendment or supplement, in reliance upon and in conformity with written information furnished to the Company by or through the Underwriter specifically for use in the preparation thereof. This indemnity agreement will be in addition to any liability which the 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.

(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 Underwriter 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 Underwriter 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 Underwriter 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 and commissions received by the Underwriter, in each case as set forth in the table 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 Underwriter 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 Underwriter agree that it would not be just and equitable if contributions pursuant to this Section 8(d) were determined by pro rata allocation 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) the Underwriter shall be required to contribute any amount in excess of the underwriting discounts and commissions applicable to the Shares purchased, and (ii) no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

(e) In any proceeding relating to the Registration Statement, 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 New York City, 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 the Underwriter or any person controlling the 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 the Underwriter, or any person controlling the 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.

All 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 Underwriter, to Deutsche Bank Securities Inc., 60 Wall Street, 4^th Floor, New York, New York 10005; Attention: Syndicate Manager, with a copy to Deutsche Bank Securities Inc., 60 Wall Street, 36^th Floor, New York, New York 10005, Attention: General Counsel, with a copy to Underwriter’s Counsel at Latham & Watkins LLP, 663 West Fifth Street, Suite 4000, Los Angeles, California 90071, Attention: Pamela B. Kelly, Esq.; and (ii) if to the Company, to Marc H. Rubinstein, Esq., and its counsel at Skadden, Arps, Slate, Meagher & Flom LLP at the addresses set forth in the Registration Statement.

(a) by notice to the Company at any time prior to the Closing Date or any Option Closing Date (if different from the Closing Date and then only as to Option Shares) if any of the following has occurred: (i) since the respective dates as of which information is given in the Registration Statement and the Prospectus, any Material Adverse Change or any development that could, in your judgment, be expected to result in a Material Adverse Change, whether or not arising in the ordinary course of business, (ii) any outbreak or escalation of hostilities or declaration of war or national emergency or other national or international calamity or crisis or change in economic or political conditions if the effect of such outbreak, escalation, declaration, emergency, calamity, crisis or change on the financial markets of the United States would, in your reasonable judgment, make it impracticable or inadvisable to market the Shares or to enforce contracts for the sale of the Shares, (iii) suspension of trading in securities generally on the New York Stock Exchange, the American Stock Exchange or the Nasdaq National Market or limitation on prices (other than limitations on hours or numbers of days of trading) for securities on either such Exchange, (iv) the enactment, publication, decree or other promulgation of any statute, regulation, rule or order of any court or other governmental authority which in your opinion materially and adversely affects or may materially and adversely affect the business or operations of the Company, (v) the declaration of a banking moratorium by United States or New York State authorities, (vi) any downgrading, or placement on any watch list for possible downgrading, in the rating of any of the Company’s debt securities by any “nationally recognized statistical rating organization” (as defined for purposes of Rule 436(g) under the Exchange Act); (vii) the suspension of trading of the Company’s Common Stock by the Nasdaq National 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 would result in a Material Adverse Change in the securities markets in the United States; or

This Agreement has been and is made solely for the benefit of the Underwriter 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 the Underwriter shall be deemed a successor or assign merely because of such purchase.

The Company and the Underwriter acknowledge and agree that the only information furnished or to be furnished by the Underwriter to the Company for inclusion in any Prospectus or the Registration Statement consists of the information set forth in the third, tenth through sixteenth and twenty-second paragraphs under the caption “Underwriting” in the Prospectus.

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.

The reimbursement, indemnification and contribution agreements contained in this Agreement and the representations, warranties and covenants in this Agreement shall remain in full force and effect regardless of (a) any termination of this Agreement, (b) any investigation made by or on behalf of the Underwriter or controlling person thereof, or by or on behalf of the Company or its directors or officers and (c) delivery of and payment for the Shares under this Agreement.

This Agreement may be executed in two or more counterparts (including by facsimile), each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.

If the foregoing letter is in accordance with your understanding of our agreement, please sign and return to us the enclosed duplicates hereof, whereupon it will become a binding agreement between the Company and the Underwriter in accordance with its terms.
