1. REPRESENTATIONS AND WARRANTIES OF THE ISSUER.

The Issuer represents and warrants to each of the Underwriters as follows:

(a) The Registration Statement has been filed with the Commission under the Securities Act and has become effective under the Securities Act. No stop order suspending the effectiveness of such registration statement is in effect, and no proceedings for such purpose are pending before or, to the knowledge of the Issuer, threatened by the Commission. The Commission has not issued any order preventing or suspending the use of any Preliminary Prospectus or any Issuer Free Writing Prospectus. Copies of such registration statement and each of the amendments thereto have been delivered by the Issuer to you. The Registration Statement conforms, and any further amendments or supplements to the Registration Statement will conform, in all material respects to the requirements of the Securities Act and the Rules and Regulations. The Prospectus and the Pricing Prospectus each conforms and, as amended or supplemented, will conform, in all material respects to the requirements of the Securities Act and the Rules and Regulations. As of the Effective Date, the date hereof, the Closing Date (as

defined below) and each Option Closing Date (as defined below), if any, the Registration Statement does not and will not, and any further amendments to the Registration Statement will not, when they become effective, 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 not misleading; as of its date and the date hereof, the Prospectus does not, and as amended or supplemented on the Closing Date and each Option Closing Date, if any, will not, contain an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; the Pricing Prospectus, as supplemented by the Issuer Free Writing Prospectuses and other documents listed in Schedule [II(a)] [III(a)] hereto, taken together with the final pricing information included on the cover page of the Prospectus (collectively, the “Disclosure Package”), as of the Applicable Time did not include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; each Issuer Free Writing Prospectus listed on Schedule [II(a)] [III(a)] or Schedule [II(b)] [III(b)] hereto does not conflict with the information contained in the Registration Statement; and each such Issuer Free Writing Prospectus listed on Schedule [II(b)] [III(b)], as supplemented by and taken together with the Disclosure Package as of the Applicable Time, did not include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that the representations and warranties set forth in this sentence do not apply to (1) statements or omissions in the Registration Statement, the Prospectus, the Pricing Prospectus or any Issuer Free Writing Prospectus or any such amendment or supplement in reliance upon and in conformity with written information furnished to the Issuer by any Underwriter through the Representative expressly for use therein, such information being listed in Section 15 below or (2) information with respect to the Selling Stockholder set forth in the Registration Statement, the Prospectus, the Pricing Prospectus or any Issuer Free Writing Prospectus or any amendment or supplement thereto in reliance upon and in conformity with written information furnished to the Issuer by such Selling Stockholder expressly for use therein, but excluding information with respect to any position, officer or other relationship that any Selling Stockholder has had with, and that is material to, the Issuer or any of its predecessors or affiliates within three years prior to the date of the Prospectus. The Company filed the Registration Statement with the Commission before using any Issuer Free Writing Prospectus and each Issuer Free Writing Prospectus was preceded or accompanied by the most recent Preliminary Prospectus satisfying the requirements of Section 10 under the Securities Act.

(b) Each of the statements made by the Issuer in such documents within the coverage of Rule 175(b) of the Rules and Regulations, including (but not limited to) any projections, results of operations or statements with respect to future available cash or future cash distributions of the Issuer, was made or will be made with a reasonable basis and in good faith. Notwithstanding the foregoing, this representation and warranty shall not apply to any statements or omissions made in reliance upon and in conformity with written information concerning the Underwriters furnished to the Issuer by or on behalf of any Underwriter specifically for inclusion in the Registration Statement, the Pricing Prospectus or the Prospectus.

(c) This Agreement has been duly authorized, executed and delivered by the Issuer, and constitutes a valid, legal, and binding obligation of the Issuer, enforceable in accordance with its terms, except as rights to indemnity hereunder may be limited by federal or state securities laws and except as such enforceability may be limited by bankruptcy, insolvency, reorganization or similar laws affecting the rights of creditors generally, and subject to general principles of equity. The Issuer has full power and authority to enter into this Agreement and to authorize, issue and sell the Shares as contemplated by this Agreement.

(d) The Issuer has been duly organized and is validly existing as a corporation in good standing under the laws of the State of Delaware, with corporate power and authority to own or lease its properties and conduct its business as described in the Prospectus and the Disclosure Package. Each of the subsidiaries of the Issuer, as listed in Exhibit 21.1 to Item 16(a) of the Registration Statement (collectively, the “Subsidiaries”), has been duly organized and is validly existing and in good standing under the laws of the jurisdiction of its incorporation or formation, with the requisite power and authority to own or lease its properties and conduct its business as described in the Prospectus and the Disclosure Package. The Subsidiaries are the only subsidiaries, direct or indirect, of the Issuer. The Issuer and each of the Subsidiaries are duly qualified to transact business and are in good standing in all jurisdictions in which the conduct of their business requires such qualification (which jurisdictions are set forth on Schedule IV hereto); except where the failure to be so qualified or to be in good standing would not have a material adverse effect on the condition (financial or otherwise), properties, assets, liabilities, rights, operations, earnings, business, management or prospects of the Issuer and its Subsidiaries taken as a whole, whether or not arising from transactions in the ordinary course of business (a “Material Adverse Effect”). The outstanding shares of capital stock or ownership interests of each of the Subsidiaries have been duly authorized and validly issued, are fully paid and non-assessable and are wholly owned by the Issuer or another Subsidiary free and clear of all liens, encumbrances and equities and claims except as otherwise hereinafter provided; and no options, warrants or other rights to purchase, agreements or other obligations to issue or other rights to convert any obligations into shares of capital stock or ownership interests in the Subsidiaries are outstanding. All shares of capital stock and ownership interests in the Subsidiaries, other than RAM Energy, Inc., have been pledged to secure the indebtedness and other obligations under that certain Third Amended and Restated Loan Agreement dated as of April 3, 2006, by and among RAM Energy, Inc., as Borrower, the Lenders named therein, and Guggenheim Corporate Funding, LLC, as Arranger and Administrative Agent.

Neither the filing of the Registration Statement nor the offering or sale of the Shares as 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.

(f) The information set forth under the caption “Capitalization” in the Prospectus and the Disclosure Package is true and correct. All of the Shares conform to the description thereof contained in the Prospectus and the Disclosure Package. The form of certificates for the Shares conforms to the corporate law of the jurisdiction of the Issuer’s incorporation. Immediately after the issuance and sale of the Shares to the Underwriters, no shares of Preferred Stock of the Issuer shall be issued and outstanding and no holder of any shares of capital stock, securities convertible into or exchangeable or exercisable for capital stock or options, warrants or other rights to purchase capital stock or any other securities of the Issuer shall have any existing or future right to acquire any shares of Preferred Stock of the Issuer. Except as described in the Prospectus and the Disclosure Package, there are no outstanding options or warrants to purchase from the Issuer or any Subsidiary of the Issuer any capital stock of the Issuer or any Subsidiary and, to the Issuer’s knowledge, there are no outstanding options or warrants held by any stockholder of the Issuer entitling such stockholder to purchase from or sell to any other stockholder of the Issuer any capital stock of the Issuer. No holders of securities of the Issuer have rights to the registration of such securities under the Registration Statement that have not been waived.

(g) The consolidated financial statements of the Issuer and the Subsidiaries, together with related notes and schedules as set forth in the Registration Statement, the Prospectus and the Disclosure Package, present fairly the financial position and the results of operations and cash flows of the Issuer and the consolidated Subsidiaries, at the indicated dates and for the indicated periods. Such financial statements and related schedules have been prepared in accordance with U.S. generally accepted accounting principles, 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.

The pro forma financial statements and other pro forma financial information included in the Registration Statement, Prospectus and the Disclosure Package present fairly the information shown therein, have been prepared in accordance with the Commission’s rules and guidelines with respect to pro forma financial statements, have been properly compiled on the pro forma bases described therein, and, in the opinion of the Issuer, the assumptions used in the preparation thereof are reasonable and the adjustments used therein are appropriate to give effect to the transactions or circumstances referred to therein. The statistical, industry-related and market-related data included in the Registration Statement, the Prospectus and the Disclosure Package are based on or derived from sources which the Issuer reasonably and in good faith believes are reliable and accurate.

There are no claims by the Issuer or any Subsidiary under any such policy or instrument as to which an insurance company is denying liability or defending under a reservation of rights clause.

(oo) Neither the Issuer nor any of its affiliates has, prior to the date hereof, made any offer or sale of any securities which could be “integrated” for purposes of the Securities Act or the rules and regulations promulgated thereunder with the offer and sale of the Shares pursuant to the Registration Statement. Except as disclosed in the Prospectus and the Disclosure Package, neither the Issuer nor any of its affiliates has sold or issued any security during the six-month period preceding the date of the Prospectus, including but not limited to any sales pursuant to Rule 144A or Regulation D or S under the Securities Act, other than shares of Common Stock issued pursuant to employee benefit plans, qualified stock option plans or the employee compensation plans or pursuant to outstanding options, rights or warrants as described in the Prospectus and the Disclosure Package.

(f) Except as disclosed by such Selling Stockholder in writing to the Representative, neither such Selling Stockholder nor any of his, her or its affiliates directly, or indirectly through one or more intermediaries, controls, or is controlled by, or is under common control with, or has any other association with (within the meaning of Article 1(q) of the By-laws of the NASD), any member firm of the NASD.

(g) The sale of the Option Securities by such Selling Stockholder pursuant hereto is not prompted by any information concerning the Issuer or any of the Subsidiaries which is not set forth in the Registration Statement. The information pertaining to such Selling Stockholder under the caption “Security Ownership of Certain Beneficial Owners and Management” in the Prospectus and the Disclosure Package is complete and accurate in all material respects.

(h) The Registration Statement does not, and any further amendments to the Registration Statement will not, when they become effective, 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 not misleading; the Prospectus does not, and as amended or supplemented will not, contain an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; and the Disclosure Package, as of the Applicable Time, did not include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that the representations and warranties set forth in this sentence apply only to (1) information with respect to such Selling Stockholder set forth in the Registration Statement, the Prospectus, the Disclosure Package or any amendment or supplement thereto in reliance upon and in conformity with written information furnished to the Issuer by such Selling Stockholder expressly for use therein and (2) information with respect to any position, officer or other relationship that any Selling Stockholder has had with, and that is material to, the Issuer or any of its predecessors or affiliates within three years prior to the date of the Prospectus.

3. PURCHASE, SALE AND DELIVERY OF THE FIRM SECURITIES AND THE OPTION SECURITIES.

(a) On the basis of the representations, warranties and covenants herein contained, and subject to the conditions herein set forth, the Issuer agrees to sell to the Underwriters and each Underwriter agrees, severally and not jointly, to purchase, at a price of $ [net price] per share, the number of Firm Securities set forth opposite the name of each Underwriter in Schedule I hereof, subject to adjustments in accordance with Section 11 hereof.

(b) Payment for the Firm Securities to be sold hereunder is to be made in Federal (same day) funds to an account designated by the Issuer against delivery of certificates therefor to the Representative for the several accounts of the Underwriters. 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 the third business day after the date of this Agreement or at such other time and date not later than five business days thereafter as you and the Issuer 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 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 Selling Stockholder hereby grants an option to the several Underwriters to purchase the Option Securities at the price per share as set forth in Section 3(a). 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, by you, as the Representative of the several Underwriters, to the Selling Stockholder setting forth the number of Option Securities as to which the several Underwriters are exercising the option, the names and denominations in which the Option Securities are to be registered and the time and date at which such certificates are to be delivered. The time and date at which certificates for Option Securities are to be delivered shall be determined by the Representative but shall not be earlier than three 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”). If the date of exercise of the option is three or more days before the Closing Date, the notice of exercise shall set the Closing Date as the Option Closing Date. The number of Option Securities to be purchased by each Underwriter shall be in the same proportion to the total number of Option Securities being purchased as the number of Firm Securities being purchased by such Underwriter bears to the total number of Firm Securities, adjusted by you in such manner as to avoid fractional shares. The option with respect to the Option Securities granted hereunder may be exercised only to cover over-allotments in the sale of the Firm Securities by the Underwriters. You, as the Representative of the several Underwriters, may cancel such option at any time prior to its expiration by giving written notice of such cancellation to the Selling Stockholder. To the extent, if any, that the option is exercised, payment for the Option Securities shall be made on the Option Closing Date in Federal (same day) funds drawn to the order of the Selling Stockholder against delivery of certificates therefor through the facilities of The Depository Trust Company, New York, New York.

(d) Certificates in negotiable form for the total number of the Shares to be sold hereunder by the Selling Stockholder have been placed in custody with Continental Stock Transfer & Trust Company as custodian (the “Custodian”) pursuant to the Custodian Agreement executed by the Selling Stockholder for delivery of all Option Securities to be sold hereunder by the Selling Stockholder. The Selling Stockholder specifically agrees that the Option Securities represented by the certificates held in custody for the Selling Stockholder under the Custodian Agreement are subject to the interests of the Underwriters hereunder, that the arrangements made by the Selling Stockholder for such custody are to that extent irrevocable, and that the obligations of the Selling Stockholder hereunder shall not be terminable by any act or deed of the Selling Stockholder (or by any other person, firm or corporation including the Issuer, the Custodian or the Underwriters) or by operation of law (including the dissolution of the corporate general partner of the Selling Stockholder) or by the occurrence of any other event or events, except as set forth in the Custodian Agreement. If any such event should occur prior to the delivery to the Underwriters of the Option Securities hereunder, certificates for the Option Securities shall be delivered by the Custodian in accordance with the terms and conditions of this Agreement as if such event has not occurred. The Custodian is authorized to receive and acknowledge receipt of the proceeds of sale of the Shares held by it against delivery of such Shares.

4. OFFERING BY THE UNDERWRITERS.

It is understood that the several Underwriters are to make a public offering of the Firm Securities as soon as the Representative deems it advisable to do so. The Firm Securities are to be initially offered to the public at the initial public offering price set forth in the Prospectus. To the extent, if at all, that any Option Securities are purchased pursuant to Section 3 hereof, the Underwriters will offer them to the public on the foregoing terms.

It is further understood that you will act as the Representative 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.

5. COVENANTS.

(a) The Issuer covenants and agrees with the several Underwriters that it will (i) prepare and timely file with the Commission under Rule 424(b) of the Rules and Regulations a Prospectus in a form approved by the Representative containing information previously omitted at the time of effectiveness of the Registration Statement in reliance on Rule 430A of the Rules and Regulations; (ii) not file any amendment to the Registration Statement or supplement to the Prospectus, any Preliminary Prospectus or any Issuer Free Writing Prospectus of which the Representative shall not previously have been advised and furnished with a copy or to which the Representative shall have reasonably objected in writing or which is not in compliance with the Rules and Regulations; and (iii) file on a timely basis all reports and any definitive proxy or information statements required to be filed by the Issuer 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 Issuer has not distributed and without the prior consent of the Representative, it will not distribute any prospectus or other offering material (including, without limitation, any offer relating to the Shares that would constitute a Free Writing Prospectus and content on the Issuer’s website that may be deemed to be a prospectus or other offering material) in connection with the offering and sale of the Shares, other than the materials referred to in Section 1(a). Each Underwriter represents and agrees that it has not made and, without the prior consent of the Issuer and the Representative, it will not make, any offer relating to the Offered Securities that would constitute an Issuer Free Writing Prospectus. Any such Issuer Free Writing prospectus the use of which has been consented to by the Issuer and the Representative is listed on Schedule [II(a)] [III(a)] or Schedule [II(b)] [III(b)] hereto. The Issuer has complied and will comply with the requirements of Rule 433 under the Securities Act applicable to any Issuer Free Writing Prospectus, including timely filing with the Commission or retention where required and legending. The Issuer represents that it has satisfied and agrees that it will satisfy the conditions under Rule 433 under the Securities Act to avoid a requirement to file with the Commission any electronic road show. The Issuer agrees that if at any time following issuance of an Issuer Free Writing Prospectus any event occurred or occurs as a result of which such Issuer Free Writing Prospectus would conflict with the information in the Registration Statement, the Pricing Prospectus or the Prospectus or would include an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in light of the circumstances then prevailing, not misleading, the Issuer will give prompt notice thereof to the Representative and, if requested by the Representative, will prepare and furnish without charge to each Underwriter an Issuer Free Writing Prospectus or other document which will correct such conflict, statement or omission; provided, however, that this covenant shall not apply to any statements or omissions in an Issuer Free Writing Prospectus made in reliance upon and in conformity with information furnished in writing to the Issuer by an Underwriter through the Representative or by the Selling Stockholder expressly for use therein.

(c) The Issuer 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 Issuer.

(d) The Issuer will advise the Representative promptly (i) when the Registration Statement or any post-effective amendment thereto shall have become effective; (ii) of receipt of any comments from the Commission; (iii) of any request of the Commission for amendment of the Registration Statement or for supplement to the Prospectus or for any additional information; and (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or the use of the Prospectus or of the institution of any proceedings for that purpose. The Issuer will use its commercially reasonable efforts to prevent the issuance of any such stop order preventing or suspending the use of the Prospectus and to obtain as soon as possible the lifting thereof, if issued.

(e) The Issuer will cooperate with the Representative in endeavoring to qualify the Shares for sale under the securities laws of such jurisdictions as the Representative 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 Issuer 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 Issuer 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 Representative may reasonably request for distribution of the Shares.

(f) The Issuer will deliver to, or upon the order of, the Representative, from time to time, as many copies of any Preliminary Prospectus as the Representative may reasonably request. The Issuer will deliver to, or upon the order of, the Representative during the period when delivery of a Prospectus is required under the Securities Act, as many copies of the Prospectus in final form, or as thereafter amended or supplemented, as the Representative may reasonably request. The Issuer will deliver to the Representative at or before the Closing Date, four signed copies of the Registration Statement and all amendments thereto including all exhibits filed therewith, and will deliver to the Representative such number of copies of the Registration Statement (including such number of copies of the exhibits filed therewith that may reasonably be requested) and of all amendments thereto, as the Representative may reasonably request.

(g) The Issuer will comply with the Securities Act and the Rules and Regulations, and 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 an Underwriter or dealer, any event shall occur as a result of which, in the judgment of the Issuer or in the reasonable opinion of the Underwriters, 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 to amend or supplement the Prospectus to comply with any law, the Issuer 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.

(h) The Issuer 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, an earning statement (which need not be audited) in reasonable detail, covering a period of at least 12 consecutive months beginning after the effective date of the Registration Statement, which earning statement shall satisfy 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.

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

(j) The Issuer covenants and agrees that no offering, sale, short sale or other disposition of any shares of Common Stock of the Issuer 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 90 days after the date of this Agreement, directly or indirectly, by the Issuer otherwise than hereunder or with the prior written consent of the Representative; provided, that this provision will not restrict the Issuer from (1) issuing shares of Common Stock pursuant to the exercise of outstanding options or warrants, (2) granting restricted stock awards with respect to, or options to purchase its Common Stock pursuant to employee benefit plans as described in the Prospectus and the Disclosure Package or (3) issuing Common Stock in connection with a business combination or acquisition in which shares of Common Stock are issued as all or part of the consideration to be received by the selling or acquired party or its stockholders. Notwithstanding the foregoing, if (1) during the last 17 days of the 90-day restricted period, the Issuer issues an earnings release or material news or a material event relating to the Issuer occurs; or (2) prior to the expiration of the 90-day restricted period, the Issuer announces that it will release earnings results during the 16-day period beginning on the last day of the 90-day period, the restrictions imposed by this Agreement shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event.

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

(l) The Issuer has caused each officer and director of the Issuer and each stockholder of the Issuer listed in Schedule V hereto to furnish to you, on or prior to the date of this agreement, a letter or letters, in form and substance satisfactory to the Underwriters, pursuant to which each such person shall agree not to offer, sell, sell short or otherwise dispose of any shares of Common Stock of the Issuer or other capital stock of the Issuer, or any other securities convertible, exchangeable or exercisable for Common Shares or derivative of Common Shares owned by such person or request the registration for the offer or sale of any of the foregoing (or as to which such person has the right to direct the disposition of) for a period of 90 days after the date of this Agreement, directly or indirectly, except with the prior written consent of the Representative (“Lockup Agreements”).

(m) The Issuer shall apply the net proceeds of its sale of the Shares as described under the heading “Use of Proceeds” in the Prospectus and the Disclosure Package and shall report to 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 Securities Act.

(n) The Issuer shall not invest, or otherwise use the proceeds received by the Issuer from its sale of the Shares in such a manner as would require the Issuer or any of the Subsidiaries to register as an investment company under the 0000 Xxx.

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

6. COVENANTS OF THE SELLING STOCKHOLDER.

The Selling Stockholder covenants and agrees with the several Underwriters that:

(a) No offering, sale, short sale or other disposition of any shares of Common Stock of the Issuer or other capital stock of the Issuer or other securities convertible, exchangeable or exercisable for Common Stock or derivative of Common Stock owned by the Selling Stockholder or request the registration for the offer or sale of any of the foregoing (or as to which the Selling Stockholder has the right to direct the disposition of) will be made for a period of 90 days after the date of this Agreement, directly or indirectly, by such Selling Stockholder otherwise than hereunder or with the prior written consent of the Representative. Notwithstanding the foregoing, if (1) during the last 17 days of the 90-day restricted period, the Issuer issues an earnings release or material news or a material event relating to the Issuer occurs; or (2) prior to the expiration of the 90-day restricted period, the Issuer announces that it will release earnings results during the 16-day period beginning on the last day of the 90-day period, the restrictions imposed by this Agreement shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event.

(b) In order to document the Underwriters’ compliance with the reporting and withholding provisions of the Tax Equity and Fiscal Responsibility Act of 1982 and the Interest and Dividend Tax Compliance Act of 1983 with respect to the transactions herein contemplated, the Selling Stockholder agrees to deliver to you prior to or at the Option Closing Date a properly completed and executed United States Treasury Department Form W-8 or W-9 (or other applicable form or statement specified by Treasury Department regulations in lieu thereof).

(c) The Selling Stockholder 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 Issuer.

7. COSTS AND EXPENSES.

(a) The Issuer will pay all costs, expenses and fees incident to the performance of the obligations of the Issuer and the Selling Stockholder under this Agreement, including, without limiting the generality of the foregoing, the following: accounting fees of the Issuer; the fees and disbursements of counsel for the Issuer and the Selling Stockholder; the cost of printing and delivering to, or as requested by, the Underwriters copies of the Registration Statement, Preliminary Prospectuses, the Pricing Prospectus, any Issuer Free Writing Prospectus, the Prospectus, the Underwriters’ Selling Memorandum and the Underwriters’ Invitation Letter,

(b) The Issuer and the Selling Stockholder shall not, however, be required to pay for any of the Underwriters’ expenses (other than those related to qualification under NASD regulation and State securities or Blue Sky laws) except that, if this Agreement shall not be consummated because the conditions in Section 8 hereof are not satisfied (excluding the conditions set forth in Sections 8(c) and 8(d)), or by reason of any failure, refusal or inability on the part of the Issuer or the Selling Stockholder 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 to satisfy said condition or to comply with said terms be due to the default or omission of any Underwriter, then the Issuer shall reimburse the several Underwriters for reasonable out-of-pocket expenses, including all 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 Issuer and the Selling Stockholder shall not in any event be liable to any of the several Underwriters for damages on account of loss of anticipated profits from the sale by them of the Shares.

(xiv) The Selling Stockholder is registered as the sole record owner of the Shares to be sold by such Selling Stockholder pursuant to this Agreement and has full legal right, power and authority, and any approval required by law (other than as required by State securities and Blue Sky laws as to which such counsel need express no opinion), to sell, assign, transfer and deliver the portion of the Shares to be sold by such Selling Stockholder.

(xv) A Power-of-Attorney and a Custody Agreement have been duly authorized, executed and delivered by such Selling Stockholder and (assuming the due authorization, execution and delivery thereof by the other parties thereto) constitute the legal, valid and binding obligations of such Selling Stockholder, enforceable against it in accordance with their respective terms, subject to applicable bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and similar laws affecting creditors’ rights and remedies generally, and subject, as to enforceability, to general principles of equity, including principles of commercial reasonableness, good faith and fair dealing (regardless of whether enforcement is sought in a proceeding at law or in equity) and except that rights to indemnification and contribution thereunder may be limited by federal or state securities laws or public policy relating thereto.

(xviii) The sale of the Shares to be sold by such Selling Stockholder under this Agreement and the performance by such Selling Stockholder of its obligations under this Agreement, the Power-of-Attorney and the Custody Agreement will not (A) constitute a default under or violate any of the terms, conditions or provisions of the Limited Partnership Agreement of such Selling Stockholder or other similar organizational documents, (B) violate Texas or federal law (other than federal and state securities or Blue Sky laws, as to which such counsel expresses no opinion), (C) constitute a default under or violate any judgment, writ, injunction, decree, order or ruling of any court or governmental authority binding on such Selling Stockholder or to which any of the property or assets of such Selling Stockholder is subject, of which such counsel is aware or (D) result in the creation or imposition of, whether with or without the giving of notice or passage of time or both, any lien or encumbrance upon the Shares to be sold by such Selling Stockholder or any property or assets of such Selling Stockholder pursuant to any contract, indenture, mortgage, deed of trust, loan or credit agreement, note, license, lease or other agreement or instrument of which such counsel is aware to which such Selling Stockholder is a party or by which such Selling Stockholder may be bound or to which any of the property or assets of such Selling Stockholder is subject; except, in the case of clauses (C) and (D), as would not, individually or in the aggregate, have a material adverse effect on such Selling Stockholder or the ability of such Selling Stockholder to consummate the offering of the Shares to be sold by it or otherwise perform its obligations under this Agreement, the Power-of-Attorney and the Custody Agreement.

In rendering its opinion, McAfee & Xxxx may rely, as to matters regarding the capitalization of the Issuer, on the opinion of Xxxxxxxx Xxxxxx, dated May 8, 2006; provided that McAfee & Xxxx shall state that they believe that they and the Underwriters are justified in relying on such opinion.

the statements therein not misleading, (ii) that the Disclosure Package, as of the Applicable Time, contained any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of circumstances under which they were made, not misleading or (iii) the Prospectus, or any supplement thereto, on the date it was filed pursuant to the Rules and Regulations and as of the Closing Date or the Option Closing Date, as applicable, contained an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements, in the light of the circumstances under which they are made, not misleading (except that such counsel need express no view as to financial statements and related schedules therein).

Xxxx & Associates, Inc. confirming in all material respects the matters described in Annex A hereto.

(g) The Representative shall have received on the Closing Date and the Option Closing Date, if any, a certificate or certificates of the Issuer’s Chief Executive Officer and Chief Financial Officer to the effect that, as of the Closing Date or the Option Closing Date, if any, each of them severally represents as follows:

(ii) The representations and warranties of the Issuer contained in Section 1 hereof are true and correct as of the Closing Date or the Option Closing Date, if any;

(iii) All filings required to have been made pursuant to Rules 424 or 430A under the Securities Act have been made;

(iv) He has carefully examined the Registration Statement and the Prospectus and, in his opinion, as of the effective date of the Registration Statement, the statements contained in the Registration Statement were true and correct, and such Registration Statement and Prospectus did not omit to state a material fact required to be stated therein or necessary in order to make the statements therein not misleading, and since the effective date of the Registration Statement, no event has occurred which should have been set forth in a supplement to or an amendment of the Prospectus which has not been so set forth in such supplement or amendment; and

9. CONDITIONS OF THE OBLIGATIONS OF THE ISSUER AND THE SELLING STOCKHOLDER.

The obligations of the Issuer and the Selling Stockholder to sell and deliver the portion of the Shares required to be delivered as and when specified in this Agreement are subject to the conditions that at the Closing Date or the Option Closing Date, if any, no stop order suspending the effectiveness of the Registration Statement shall have been issued and in effect or proceedings therefor initiated or threatened.

10. INDEMNIFICATION.

(a) The Issuer agrees:

(i) to indemnify and hold harmless each Underwriter and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act, against any losses, claims, damages or liabilities to which such Underwriter or any such controlling person may become subject under the Securities 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 (A) the Registration Statement, any Preliminary Prospectus, the Pricing Prospectus, the Prospectus or any amendment or supplement thereto, (B) any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act, (ii) 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) 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) or (ii) above (provided, however, that the Issuer shall not be liable under this clause (iii) to the extent that it is determined in a final judgment by a court of competent jurisdiction that such loss, claim, damage, liability or action resulted directly from any such acts or failures to act undertaken or omitted to be taken by such Underwriter through its gross negligence or willful misconduct); provided, however, that the Issuer 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, Pricing Prospectus, the Prospectus, or such amendment or supplement, or any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act in reliance upon and in conformity with written information furnished to the Issuer by or through the Representative specifically for use in the preparation thereof, such information being listed in Section 15 below.

(ii) to reimburse each Underwriter 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 Issuer, each of its directors, each of its officers who have signed the Registration Statement, the Selling Stockholder and each person, if any, who controls the Issuer or the Selling Stockholder within the meaning of Section 15 of the Securities Act, against any losses, claims, damages or liabilities to which the Issuer or any such director, officer, Selling Stockholder or controlling person may become subject under the Securities 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, the Pricing Prospectus, the Prospectus or any amendment or supplement thereto, or in any Issuer Free Writing Prospectus (ii) 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 Issuer or any such director, officer, Selling Stockholder 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, the Pricing Prospectus, the Prospectus or any amendment or supplement thereto, or in any Issuer Free Writing Prospectus in reliance upon and in conformity with written information furnished to the Issuer by or through the Representative specifically for use in the preparation thereof, such information being listed in Section 15 below.

(c) The Selling Stockholder agrees to indemnify the Underwriters and each person, if any, who controls any Underwriter within the meaning of the Securities Act, against any losses, claims, damages or liabilities to which such Underwriter or controlling person may become subject under the Securities Act or otherwise to the same extent as indemnity is provided by the Issuer pursuant to Section 10(a) above. In no event, however, shall the liability of the Selling Stockholder for indemnification under this Section 10(c) exceed the proceeds received by the Selling Stockholder from the Underwriters in the offering. This indemnity obligation will be in addition to any liability that the Issuer may otherwise have.

(d) 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, 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 10(a) or (b) or (c) shall be available to any party who shall fail to give notice as provided in this Subsection 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 10(a) or (b) or (c). 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 satisfactory to such indemnified party and shall pay as incurred the 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 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 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 10(a) and by the Issuer and the Selling Stockholder in the case of parties indemnified pursuant to Section 10(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 incurred by the indemnified party under the terms 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.

(e) If the indemnification provided for in this Section is unavailable to or insufficient to hold harmless an indemnified party under Section 10(a) or (b) or (c) 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 Issuer and the Selling Stockholder 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 Issuer and the Selling Stockholder 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 Issuer and the Selling Stockholder 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 Issuer and the Selling Stockholder bear to the total underwriting discounts and commissions received by the Underwriters, 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 Issuer or the Selling Stockholder 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 Issuer, the Selling Stockholder and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Subsection 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 Subsection. 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 Subsection 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, (i) no Underwriter shall be required to contribute any amount in excess of the underwriting discounts and commissions 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 Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation, and (iii) the Selling Stockholder shall not be required to contribute any amount in excess of the proceeds received by such Selling Stockholder from the Underwriters in the offering. The Underwriters’ obligations in this Subsection to contribute are several in proportion to their respective underwriting obligations and not joint.

(f) In any proceeding relating to the Registration Statement, any Preliminary Prospectus, the Pricing Prospectus, the Prospectus or any supplement or amendment thereto, or any Issuer Free Writing Prospectus, each party against whom contribution may be sought under this Section hereby consents to the jurisdiction of any court having jurisdiction over any other contributing party, agrees that process issuing from such court may be served upon him or it by any other contributing party and consents to the service of such process and agrees that any other

contributing party may join him or it as an additional defendant in any such proceeding in which such other contributing party is a party.

(g) Any losses, claims, damages, liabilities or expenses for which an indemnified party is entitled to indemnification or contribution under this Section 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 and the representations and warranties of the Issuer and the Selling Stockholder 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 or any person controlling any Underwriter, the Issuer, its directors or officers, the Selling Stockholder, or any persons controlling the Issuer or the Selling Stockholder, (ii) acceptance of any Shares and payment therefor hereunder, and (iii) any termination of this Agreement. A successor to any Underwriter, or to the Issuer, its directors or officers, or any person controlling the Issuer, shall be entitled to the benefits of the indemnity, contribution and reimbursement agreements contained in this Section.

11. DEFAULT BY UNDERWRITERS.

If on the Closing Date or the Option Closing Date, if any, 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 Issuer or the Selling Stockholder), you, as the Representative of the Underwriters, shall use your reasonable efforts to procure within 36 hours thereafter one or more of the other Underwriters, or any others, to purchase from the Issuer and the Selling Stockholder such amounts as may be agreed upon and upon the terms set forth herein, the Firm Securities or Option Securities, as the case may be, which the defaulting Underwriter or Underwriters failed to purchase. If during such 36 hours you, as such Representative, shall not have procured such other Underwriters, or any others, to purchase the Firm Securities or Option Securities, as the case may be, agreed to be purchased by the defaulting Underwriter or Underwriters, then (a) if the aggregate number of shares with respect to which such default shall occur does not exceed 10% of the Firm Securities or Option Securities, as the case may be, covered hereby, the other Underwriters shall be obligated, severally, in proportion to the respective numbers of Firm Securities or Option Securities, as the case may be, which they are obligated to purchase hereunder, to purchase the Firm Securities or Option Securities, as the case may be, which such defaulting Underwriter or Underwriters failed to purchase, or (b) if the aggregate number of shares of Firm Securities or Option Securities, as the case may be, with respect to which such default shall occur exceeds 10% of the Firm Securities or Option Securities, as the case may be, covered hereby, the Issuer and the Selling Stockholder or you as the Representative of the Underwriters will have the right to terminate this Agreement without liability on the part of the non-defaulting Underwriters or of the Issuer or of the Selling Stockholder except to the extent provided in Section 10 hereof. In the event of a default by any Underwriter or Underwriters, as set forth in this Section, the Closing Date or Option Closing Date, if any, may be postponed for such period, not exceeding seven days, as you, as Representative, may determine in order that the required changes in the Registration Statement 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 shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

to enforce contracts for the sale of the Shares, or (iii) suspension of trading in securities generally on the New York Stock Exchange or the American Stock Exchange 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 Issuer, (v) 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 the Issuer’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 Issuer’s common stock by The Nasdaq Capital 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 Sections 8 and 11 of this Agreement.

14. SUCCESSORS.

This Agreement has been and is made solely for the benefit of the Issuer, the Selling Stockholder and Underwriters 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.

15. INFORMATION PROVIDED BY UNDERWRITERS.

The Underwriters severally confirm and the Issuer and the Selling Stockholder acknowledge and agree that the statements with respect to the public offering of the Shares by the Underwriters set forth on the cover page of, the statements related to release of the lockup agreements, the sentences related to concession and reallowance figures, and the statements relating to stabilization by the Underwriters appearing under the caption “Underwriting” in, the most recent Preliminary Prospectus and the Prospectus are correct and constitute the only information concerning such Underwriters furnished in writing to the Issuer by or on behalf of the Underwriters specifically for inclusion in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto.

16. RESEARCH INDEPENDENCE. In addition, the Issuer acknowledges that the Underwriters’ research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and that such Underwriters’ research analysts may hold and make statements or investment recommendations and/or publish research reports with respect to the Issuer and/or the offering that differ from the views of its investment bankers. The Issuer hereby waives and releases, to the fullest extent permitted by law, any claims that the Issuer may have against the Underwriters with respect to any conflict of interest that may arise from the fact that the views

expressed by their independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Issuer by such Underwriters’ investment banking divisions. The Issuer acknowledges that each of the Underwriters is a full service securities firm and as such from time to time, subject to applicable securities laws, may effect transactions for its own account or the account of its customers and hold long or short position in debt or equity securities of the companies which may be the subject to the transactions contemplated by this Agreement.

17. NO FIDUCIARY DUTY.

Notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the underwriters, the Issuer and the Selling Stockholder acknowledge and agree that:

(a) nothing herein shall create a fiduciary or agency relationship between the Issuer and the Underwriters or between the Selling Stockholder and the Underwriters;

(b) the Underwriters are not acting as advisors, expert or otherwise, to the Issuer or the Selling Stockholder in connection with this offering, sale of the Shares or any other services the Underwriters may be deemed to be providing hereunder, including, without limitation, with respect to the public offering price of the Shares;

(c) the relationships between the Issuer and the Underwriters and between the Selling Stockholder and the Underwriters are entirely and solely commercial, based on arms-length negotiations;

(d) any duties and obligations that the Underwriters may have to the Issuer and the Selling Stockholder shall be limited to those duties and obligations specifically stated herein; and

(e) notwithstanding anything in this Underwriting Agreement to the contrary, the Issuer and the Selling Stockholder acknowledge that the Underwriters may have financial interests in the success of the Offering that are not limited to the difference between the price to the public and the purchase price paid to the Issuer and the Selling Stockholder by the Underwriters for the Shares and the Underwriters have no obligation to disclose, or account to the Issuer or the Selling Stockholder for, any of such additional financial interests.

The Issuer and the Selling Stockholder hereby waive and release, to the fullest extent permitted by law, any claims that the Issuer or the Selling Stockholder may have against the Underwriters with respect to any breach or alleged breach of fiduciary duty.

18. MISCELLANEOUS.

(a) 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 any Underwriter or controlling person thereof, or by or on

behalf of the Issuer or its directors or officers, or by or on behalf of the Selling Stockholder and (c) delivery of and payment for the Shares under this Agreement.

(b) This Agreement may be executed in counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.
