c/o W.R. Hambrecht + Co., LLC

420 Lexington Avenue, Suite 1820

New York, New York 10036

Dear Sir or Madam:

WhiteGlove House Call Health, Inc., a Delaware corporation (the “Company”), proposes, subject to the terms and conditions contained in this Underwriting Agreement (this “Agreement”), to issue and sell up to an aggregate of 2,500,000 shares of common stock (the “Firm Shares”), par value $0.0001 per share (the “Common Stock”), to you and the other underwriters (the “Underwriters”) named on Schedule 5 to this Agreement, for whom you are acting as Representative (the “Representative”) in a public offering. The stockholders of the Company named in Schedule 2 attached hereto (the “Selling Stockholders”) propose, severally and not jointly and subject to the terms and conditions stated herein, to grant to the Underwriters an option to purchase up to an aggregate of 375,000 shares of Common Stock (the “Over-allotment Option” and such shares, the “Option Shares”) for the purpose of covering over-allotments in connection with the sale of the Firm Shares. The Firm Shares and Option Shares are herein called the “Shares.” The respective amounts of the Firm Shares to be purchased by each of the Underwriters is set forth opposite its name on Schedule 5 hereto. The Shares are more fully described in the Registration Statement (as hereinafter defined).

As used in this Agreement, the term “knowledge” with respect to the Company means the knowledge of any of the persons listed on Schedule 4 hereto.

The Company and the Selling Stockholders hereby confirm as follows their agreements with the Underwriters.

1. Agreement to Act as Underwriters.

(i) On the basis of the representations, warranties and agreements of the Company herein contained and subject to all the terms and conditions of this Agreement, the Company agrees to sell to each of the Underwriters, and each of the Underwriters agrees, severally and not jointly, to purchase from the Company, at a purchase price of $[ ] per share (the “Initial Price”), the number of Firm Shares (rounded up or down, as determined by the Representative in its discretion, in order to avoid fractional shares) obtained by multiplying 2,500,000 Firm Shares by a fraction the numerator of which is the number of Firm Shares set forth opposite the name of such Underwriter in Schedule 5 hereto and the denominator of which is the total number of Firm Shares, subject to adjustment in accordance with Section 10 hereof. The Company shall pay to the

Underwriters a fee equal to 7.5% (the “Underwriting Discount”) of the gross offering proceeds received by the Company from the sale of the Firm Shares as set forth on the cover page of the Final Prospectus (as hereinafter defined).

(ii) The Selling Stockholders hereby grant to the several Underwriters an option to purchase, severally and not jointly, all or any part of the Option Shares at the Initial Price. The Selling Stockholders agree, severally and not jointly, to sell to the Underwriters the respective numbers of Option Shares obtained by multiplying the number of Option Shares specified in such notice by a fraction the numerator of which is the number of shares set forth opposite the names of such Selling Stockholders in Schedule 2 hereto under the caption “Maximum Number of Option Shares to be Sold” and the denominator of which is the total number of Option Shares (subject to adjustment by the Representative to eliminate fractional shares). The number of Option Shares to be purchased by each Underwriter shall be the same percentage (adjusted by the Representative to eliminate fractions) of the total number of Option Shares to be purchased by the Underwriters as such Underwriter is purchasing of the Firm Shares. Such option may be exercised only to cover over-allotments in the sales of the Firm Shares by the Underwriters and may be exercised in whole or in part at any time on or before 12:00 noon, New York City time, on the business day before the Firm Shares Closing Date (as defined below), and from time to time thereafter within 30 days after the date of this Agreement, in each case upon written, facsimile or electronic notice, by the Representative to the Company no later than 12:00 noon, New York City time, on the business day before Firm Shares Closing Date or at least two business days before the Option Shares Closing Date (as defined below), as the case may be, setting forth the number of Option Shares to be purchased and the time and date (if other than the Firm Shares Closing Date) of such purchase. The Underwriters will not be under any obligation to purchase any Option Shares prior to the exercise of the over-allotment option. The Selling Stockholders shall pay to the Underwriters the Underwriting Discount with respect to gross proceeds received by the Selling Stockholders from the Underwriters for the sale of the Option Shares.

(iii) The Company and the Selling Stockholders understand that the Underwriters propose to make a public offering of the Shares, as set forth in and pursuant to the Prospectus (as defined below) as soon after the Effective Time (as defined below) and the date of this Agreement as the Representative deems advisable. The Company and the Selling Stockholders hereby confirm that the Underwriters and dealers have been authorized to distribute the Prospectus (as from time to time amended or supplemented if the Company furnishes amendments or supplements thereto to the Underwriters).

2. Delivery and Payment.

(i) Payment of the purchase price for and delivery of certificates for the Firm Shares shall be made at the offices of W.R. Hambrecht + Co, LLC, [ ] at [ ], on the third business day following the date of this Agreement or at such time on such other date, not later than ten (10) business days after the date of this Agreement, as shall be agreed upon by the Company and the Representative (such time and date of delivery and payment are called the “Firm Shares Closing Date”). In addition, in the event that any or all of the Option Shares are purchased by the Underwriters, payment of the purchase price, and delivery of the certificates, for such Option Shares shall be made at the above-mentioned offices, or at such other place as shall be agreed upon by the Representative and the Company, on each date of delivery as specified in the notice from the Representative to the Company (such time and date of delivery and payment are called the “Option Shares Closing Date”). The Firm Shares Closing Date and any Option Shares Closing Date and any Option Shares Closing Date are called, individually, a “Closing Date” and, together, the “Closing Dates.”

(ii) Payment for the Shares shall be made to the Company and the Selling Stockholders by wire transfer of immediately available funds or by one or more certified or official bank check or checks in same day funds drawn to the order of the Company, and to the Selling Stockholders for the shares purchased from the Selling Stockholders, against delivery of the respective certificates to the Representative for the respective accounts of the Underwriters of certificates for the Shares to be purchased by them.

(iii) Certificates evidencing the Shares shall be registered in such names and shall be in such denominations as the Representative shall request at least two full business days before the Firm Shares Closing Date or, in the case of Option Shares, on the day of notice of exercise of the option as described in Section 1(ii) and shall be delivered by or on behalf of the Company to the Representative through the facilities of the Depository Trust Company (“DTC”) for the account of such Underwriter. The Company will cause the certificates representing the Shares to be made available for checking and packaging, at such place as is designated by the Representative, on the full business day before the Firm Shares Closing Date (or the Option Shares Closing Date in the case of the Option Shares). Time shall be of the essence, and delivery at the time and place specified pursuant to this Agreement is a further condition to the obligation of each Underwriter hereunder.

For the avoidance of doubt, in the case of any Issuer Free Writing Prospectus filed with the Commission pursuant to Rule 433(f) of the Act, the representations contained in Sections 3(i)(g) and 3(i)(i) hereof shall not apply to statements contained in an article or other written communication published or distributed by media and reproduced in such Issuer Free Writing Prospectus, except to the extent such statements are directly attributable to a director, officer or employee of the Company or its Subsidiaries and to the extent such statements are not otherwise clarified or corrected in such Issuer Free Writing Prospectus.

(h) Each Issuer Free Writing Prospectus conformed or will conform in all material respects to the requirements of the Act and the Rules and Regulations on the date of first use, and the Company has complied with any filing requirements applicable to such Issuer Free Writing Prospectus required by the Rules and Regulations. The Company has not made, and will not make, any offer relating to the Firm Shares that would constitute an Issuer Free Writing Prospectus without the prior written consent of the Underwriters.

The Company is duly licensed or qualified to do business and in good standing as a foreign organization in all jurisdictions in which the nature of the activities conducted by it or the character of the assets owned or leased by it makes such licensing or qualification necessary, except where the failure to be so qualified or in good standing or have such power or authority would not, individually or in the aggregate, have a material adverse effect or would not reasonably be expected to have a material adverse effect on or affecting the business, prospects, properties, management, consolidated financial position, stockholders’ equity or results of operations of the Company and its Subsidiaries (as defined below) taken as a whole (a “Material Adverse Effect”). Complete and correct copies of the certificate of incorporation and of the bylaws of the Company and all amendments thereto have been made available to the Underwriters, and no changes therein will be made subsequent to the date hereof and prior to the Closing Date.

(k) The Company has no subsidiaries, nor does it own a controlling interest in any entity other than those entities set forth on Schedule 2 to this Agreement (each a “Subsidiary” and collectively the “Subsidiaries”). Each Subsidiary has been duly organized and is validly existing as a corporation in good standing under the laws of its jurisdiction of formation. Each Subsidiary is duly qualified and in good standing as a foreign corporation in each jurisdiction in which the character or location of its properties (owned, leased or licensed) or the nature or conduct of its business makes such qualification necessary, except for those failures to be so qualified or in good standing which would not be reasonably expected to have a Material Adverse Effect. All of the shares of issued capital stock of each corporate subsidiary, and all of the capital stock and equity interests of each subsidiary that is not a corporation, have been duly authorized and validly issued, are fully paid and non-assessable and are owned directly or indirectly by the Company, free and clear of any lien, encumbrance, claim, security interest, restriction on transfer, shareholders’ agreement, voting trust or other defect of title whatsoever.

The Company has an authorized, issued and outstanding capitalization as set forth in the Final Prospectus as of the dates referred to therein. The descriptions of the Shares and the Common Stock of the Company in the Registration Statement and the Final Prospectus are, and at the Applicable Time will be, complete and accurate in all material respects. Except as set forth in the Registration Statement and the Final Prospectus, the Company does not have outstanding any options to purchase, or any rights or warrants to subscribe for, or any securities or obligations convertible into, or exchangeable for, or any contracts or commitments to issue or sell, any shares of capital stock or other securities.

(m) The Company has full legal right, power and authority to enter into this Agreement and perform the transactions contemplated hereby. This Agreement has been authorized and validly executed and delivered by the Company and is a legal, valid and binding agreement of the Company enforceable against the Company in accordance with its terms, subject to the effect of applicable bankruptcy, insolvency or similar laws affecting creditors’ rights generally and equitable principles of general applicability.

(n) The issuance and sale of the Firm Shares have been duly authorized by the Company, and the Firm Shares, when issued and paid for in accordance with this Agreement, will be duly and validly issued, fully paid and nonassessable and will not be subject to preemptive or similar rights. The holders of the Firm Shares will not be subject to personal liability by reason of being such holders. The Firm Shares, when issued, will conform to the description thereof set forth in the Final Prospectus in all material respects.

(o) The consolidated financial statements and the related notes included in the Registration Statement and the Final Prospectus present fairly, in all material respects, the financial condition of the Company and its consolidated Subsidiaries as of the dates thereof and the results of operations and cash flows at the dates and for the periods covered thereby in conformity with generally accepted accounting principles (“GAAP”). No other financial statements or schedules of the Company, any Subsidiary or any other entity are required by the Act or the Rules and Regulations to be included in the Registration Statement or the Final Prospectus. The pro forma financial statements contained in the Final Prospectus and the Registration Statement are based on reasonable assumptions and provide a reasonable basis for presenting the significant effects directly attributable to the transactions and events described therein, the related pro forma adjustments give appropriate effect to those assumptions, and the pro forma adjustments reflect the proper application of those adjustments to the historical financial statement amounts in the pro forma financial statements included in the Final Prospectus and the Registration Statement. The pro forma financial statements included in the Final Prospectus and the Registration Statement comply as to form in all material respects with the applicable accounting requirements of Regulation S-X under the Act and the pro forma adjustments have been properly applied to the historical amounts in the compilation of those statements. There are no off-balance sheet arrangements (as defined in Regulation S-K Item 303(a)(4)(ii)) that may have a material current or future effect on the Company’s financial condition, changes in financial condition, results of operations, liquidity, capital expenditures or capital resources.

(p) Crowe Horwath (the “Accountants”), who have reported on the consolidated financial statements and schedules described in Section 3(i)(o), are registered independent public accountants with respect to the Company as required by the Act and the Rules and Regulations and by the rules of the Public Accounting Oversight Board. The consolidated financial statements of the Company and the related notes and schedules included in the Registration Statement and

the Final Prospectus comply as to form in all material respects with the requirements of the Act and the Rules and Regulations and present fairly the information shown therein.

(q) The Company is not an “ineligible issuer” as defined under Rule 405 under the Act, and the Company has paid the registration fee for this offering as required under the Act or will pay such fees within the time period required by the Act.

(r) In reliance on the exemptions contained in Section 809 of the NYSE Amex U.S. Company Guide and consistent with the exemptions afforded in Rule 10A-3 under the Exchange Act, (A) the Company maintains an audit committee that meets the listing standards imposed by NYSE Amex for companies whose stock is listed on that exchange, the Act, the Exchange Act and the Rules and Regulations, and (B) the members of the Company’s audit committee are independent of the Company to the extent required by such listing standards, the Act, the Exchange Act and the Rules and Regulations.

(s) The Company is, and at the Closing Date will be, in compliance with all provisions of the Sarbanes-Oxley Act of 2002, as amended (“SOX”), which are applicable to it at such time. The Company and each Subsidiary maintain a system of internal controls, including, but not limited to, disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act), internal controls over accounting matters and financial reporting (as defined in Rule 13a-15(f) under the Exchange Act), an internal audit function and legal and regulatory compliance controls (collectively, “Internal Controls”) sufficient to provide reasonable assurance that (1) transactions are executed in accordance with management’s general or specific authorization; (2) transactions are recorded as necessary to permit preparation of financial statements in conformity with generally accepted accounting principles and to maintain accountability for assets; (3) access to assets is permitted only in accordance with management’s general or specific authorization; (4) the recorded accountability for assets is compared with existing assets at reasonable intervals and appropriate action is taken with respect to any differences; and (5) material information relating to the Company and its Subsidiaries is made known to the Company’s principal executive officer and principal financial officer by others within those entities and such Internal Controls are effective. The Internal Controls are, or upon consummation of the offering of the Shares will be overseen by the Audit Committee (the “Audit Committee”) of the Board in accordance with the Exchange Act and the rules promulgated thereunder. There is no significant deficiency, material weakness, change in Internal Controls or fraud involving management or other employees who have a role in Internal Controls (each, an “Internal Control Event”), or any violation of, or failure to comply with the Act, Exchange Act, the Rules and Regulations, or SOX, or any matter which, if determined adversely, would have a Material Adverse Effect. A member of the Audit Committee has confirmed to the principal executive officer or principal financial officer that, except as set forth in the Registration Statement and the Final Prospectus, the Audit Committee is not reviewing or investigating, and the Company’s independent auditors have not recommended that the Audit Committee review or investigate, (A) adding to, deleting, changing the application

(u) Since the date as of which information is given in the most recent Preliminary Prospectus, neither the Company nor any Subsidiary has entered or will before the Closing enter into any transaction or agreement, not in the ordinary course of business, that is material to the Company and its Subsidiaries taken as a whole or incurred or will incur any liability or obligation, direct or contingent, not in the ordinary course of business, that is material to the Company and its Subsidiaries taken as a whole, and neither the Company nor any Subsidiary has any plans to do any of the foregoing.

(v) The Company and each Subsidiary has good and valid title in fee simple to all items of real property and good and valid title to all personal property described in the Registration Statement or the Final Prospectus as being owned by them, in each case free and clear of all liens, encumbrances and claims except those that (1) do not materially interfere with the use made and proposed to be made of such property by the Company and its Subsidiaries or (2) would not reasonably be expected, individually or in the aggregate, to have a Material Adverse Effect.

(x) There are no legal, governmental or regulatory actions, suits or proceedings pending, nor, to the Company’s knowledge, any legal, governmental or regulatory investigations, to which the Company or any Subsidiary is a party or to which any property of the Company or any Subsidiary is the subject that, individually or in the aggregate, if determined adversely to the Company or any Subsidiary, would reasonably be expected to have a Material Adverse Effect or materially and adversely affect the ability of the Company to perform its obligations under this Agreement; to the Company’s knowledge, no such actions, suits or proceedings are threatened or contemplated by any governmental or regulatory authority or threatened by others; and there are no current or pending legal, governmental or regulatory investigations, actions, suits or proceedings that are required under the Act to be described in the Final Prospectus that are not so described.

(viii) At the Closing Date, there shall be furnished to the Underwriters a certificate, dated the date of its delivery, signed by each of the Chief Executive Officer and the Chief Financial Officer of the Company, in form and substance satisfactory to the Underwriters to the effect that each signer has carefully examined the Registration Statement, the Final Prospectus and the Pricing Disclosure Materials, and that to each of such person’s knowledge:

(b) Each of the representations and warranties of the Company contained in this Agreement were, when originally made, and are, at the time such certificate is delivered, true and correct in all

respects for those representations and warranties qualified by materiality and in all material respects for those representations and warranties that are not qualified by materiality.

(e) Subsequent to the date of the most recent financial statements in the Final Prospectus, there has been no Material Adverse Change.

(ix) At the Closing Date, there shall be furnished to the Underwriters a certificate, dated the date of its delivery, signed by each of the Selling Stockholders, in form and substance satisfactory to the Underwriters to the effect that (a) each of the representations and warranties of such Selling Stockholder contained in this Agreement were, when originally made, and are, at the time such certificate is delivered, true and correct in all respects for those representations and warranties qualified by materiality and in all material respects for those representations and warranties that are not qualified by materiality and (b) each of the covenants required herein to be performed by such Selling Stockholder on or prior to the date of such certificate has been duly, timely and fully performed and each condition herein required to be complied with by such Selling Stockholder on or prior to the delivery of such certificate has been duly, timely and fully complied with.

8. Indemnification.

(i) The Company shall indemnify and hold harmless each Underwriter, its directors, officers, employees and agents and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act (each an “Indemnified Party”), from and against any and all losses, claims, liabilities, expenses and damages, joint or several, (including any and all investigative, legal and other expenses reasonably incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claim asserted (whether or not such Indemnified Party is a party thereto)), to which it, or any of them, may become subject under the Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, liabilities, expenses or damages arise out of or are based on (a) any untrue statement or alleged untrue statement made by the Company in Section 3(i) of this Agreement, (b) any untrue statement or alleged untrue statement of any material fact contained in (1) any Preliminary Prospectus, the Registration Statement or the Final Prospectus or any amendment or supplement thereto, (2) any Issuer Free Writing Prospectus or any amendment or supplement thereto, (3) any Permitted Issuer Information used or referred to in any “free writing prospectus” (as defined in Rule 405) by any Underwriter or (4) any application or other document, or any amendment or supplement thereto, executed by the Company based upon written information furnished by or on behalf of the Company filed in any jurisdiction in order to qualify the Shares under the securities or Blue Sky laws thereof or filed with the

Commission or any securities association or securities exchange (each, an “Application”), or (c) the omission or alleged omission to state in any Preliminary Prospectus, the Registration Statement, the Final Prospectus or any Issuer Free Writing Prospectus, or any amendment or supplement thereto, or in any Permitted Issuer Information or any Application a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading; provided, however, that the Company will not be liable to the extent that such loss, claim, liability, expense or damage arises from the sale of the Shares in the public offering to any person and is based solely on an untrue statement or omission or alleged untrue statement or omission made in reliance on and in conformity with written information furnished to the Company by any Indemnified Party through the Representatives expressly for use expressly for inclusion in the Registration Statement, any Preliminary Prospectus, the Final Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Permitted Issuer Information or any Application, it being understood and agreed that the only such information furnished by any Indemnified Party consists of the information described as such in subsection (iii) below. This indemnity agreement will be in addition to any liability which the Company may otherwise have.

(ii) Each of the Selling Stockholders, severally and not jointly, will indemnify and hold harmless each Indemnified Party from and against any and all losses, claims, liabilities, expenses and damages, joint or several, (including any and all investigative, legal and other expenses reasonably incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claim asserted (whether or not such Indemnified Party is a party thereto)), to which such Indemnified Party may become subject, under the Act or otherwise, insofar as such losses, claims, liabilities expenses or damages (or actions, suits or proceedings in respect thereof) arise out of or are based upon (a) any untrue statement or alleged untrue statement made by a Selling Stockholder in Section 3(ii) of this Agreement, (b) any untrue statement or alleged untrue statement of any material fact contained in (1) any Preliminary Prospectus, the Registration Statement or the Final Prospectus or any amendment or supplement thereto, (2) any Issuer Free Writing Prospectus or any amendment or supplement thereto, (C) any Permitted Issuer Information used or referred to in any “free writing prospectus” by any Underwriter or (D) any Application executed by such Selling Stockholder based upon written information furnished by or on behalf of such Selling Stockholder filed in any jurisdiction in order to qualify the Shares under the securities or Blue Sky laws thereof or filed with the Commission or any securities association or securities exchange, or (c) the omission or alleged omission to state in any Preliminary Prospectus, the Registration Statement, the Final Prospectus or any Issuer Free Writing Prospectus, or any amendment or supplement thereto, or in any Permitted Issuer Information or any Application a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Preliminary Prospectus, the Registration Statement, the Final Prospectus or any Issuer Free Writing Prospectus, or any amendment or supplement thereto, or in any Permitted Issuer

Information or any Application, in reliance upon and in conformity with the Selling Stockholder Information furnished to the Company by such Selling Stockholder; provided, that such Selling Stockholder shall 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, the Pricing Prospectus or the Final 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 Company by any Indemnified Party through the Representatives expressly for use therein, it being understood and agreed that the only such information furnished by any Indemnified Party consists of the information described as such in subsection (iii) below. This indemnity agreement will be in addition to any liability which the Selling Stockholders may otherwise have.

(iii) Each Underwriter will severally and not jointly indemnify and hold harmless the Company and each Selling Stockholder against any losses, claims, damages or liabilities to which the Company or each Selling Stockholder may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Prospectus or the Final Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, any Preliminary Prospectus or the Final Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, in reliance upon and in conformity with written information furnished to the Company by such Underwriter through the Representatives expressly for use therein; and will reimburse the Company and each Selling Stockholder for any legal or other expenses reasonably incurred by the Company or such Selling Stockholder in connection with investigating or defending any such action or claim as such expenses are incurred. The Company and the Selling Stockholders acknowledge that, for all purposes under this Agreement, the statements set forth in the “Plan of Distribution” section under the subsections entitled “The OpenIPO Auction Process,” “Determination of Initial Public Offering Price,” “Allocation of Shares,” “Closing of the Auction and Allocation of Shares,” “Requirements for Valid Bids,” “Indemnity,” “Foreign Regulatory Restrictions on Purchase of Our Common Stock” and “Requirements for Valid Bids,” and the third paragraph under the subsection entitled “Lock-Up Agreements” in any Preliminary Prospectus and the Final Prospectus constitute the only information relating to the Underwriters furnished in writing to the Company by the Underwriters expressly for inclusion in the Registration Statement, any Preliminary Prospectus or the Final Prospectus.

(iv) Promptly after receipt by an indemnified party under subsection (i), (ii) or (iii) above of notice of the commencement of any action, such

indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under such subsection. In case any such action 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 (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (a) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (b) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

(v) If the indemnification provided for in this Section 8 is unavailable to or insufficient to hold harmless an indemnified party under subsection (i), (ii) or (iii) above in respect of any losses, claims, damages or liabilities (or actions 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 in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Selling Stockholders 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 or if the indemnified party failed to give the notice required under subsection (iv) above, 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 and the Selling Stockholders 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 in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company and the Selling Stockholders on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company and the Selling Stockholders bear to the total Underwriting Discount received by the Underwriters, in each case as set forth in the table on the cover page of the Final 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 or the Selling Stockholders on the one hand or the Underwriters on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company, each of the Selling Stockholders and the Underwriters agree that it would not be just and equitable if contribution pursuant to this subsection (v) 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 (v). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (v) 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 (v), no Underwriter shall be required to contribute any amount in excess of the Underwriting Discount applicable to the Shares. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this subsection (v) to contribute are several in proportion to their respective underwriting obligations and not joint.

9. Termination.

(i) The obligations of the Underwriters under this Agreement may be terminated at any time prior to the Closing Date, by notice to the Company from the Representatives, without liability on the part of the Underwriters to the Company or the Selling Stockholders if, prior to delivery and payment for the Shares, in the sole judgment of the Representatives: (a) there has occurred any material adverse change in the securities markets or any event, act or occurrence that has materially disrupted, or in the opinion of the Representatives, will in the future materially disrupt, the securities markets or there shall be such a material adverse change in general financial, political or economic conditions or the effect of international conditions on the financial markets in the United States is such as to make it, in the judgment of the Representatives, inadvisable or impracticable to market the Shares or enforce contracts for the sale of the Shares; (b) there has occurred any outbreak or material escalation of hostilities or other calamity or crisis the effect of which on the financial markets of the United States is such as to make it, in the judgment of the Representatives, inadvisable or impracticable to market the Shares or enforce contracts for the sale of the Shares; (c) trading in the Shares or any securities of the Company has been suspended or materially limited by the Commission or trading generally on the New York Stock Exchange, Inc., NYSE Amex or the Nasdaq Stock Market LLC has been suspended or materially limited, or minimum or maximum ranges for prices for securities shall have been fixed, or maximum ranges for prices for securities have been required, by any of said exchanges or by such system or by order of the Commission, FINRA, or any other governmental or regulatory authority; (d) a banking moratorium has been declared by any state or Federal authority; or (e) in the judgment of the Representatives, there has been,

since the time of execution of this Agreement or since the respective dates as of which information is given in the Final Prospectus, any material adverse change in the assets, properties, condition, financial or otherwise, or in the results of operations, business affairs or business prospects of the Company and its Subsidiaries considered as a whole, whether or not arising in the ordinary course of business.

(ii) If this Agreement shall be terminated pursuant to any of the provisions hereof, or if the sale of the Shares provided for herein is not consummated because any condition to the obligations of the Underwriters set forth herein is not satisfied or because of any refusal, inability or failure on the part of the Company or the Selling Stockholders to perform any agreement herein or comply with any provision hereof, the Company will, subject to demand by the Underwriters, reimburse the Underwriters for all out-of-pocket expenses incurred in connection herewith.

10. Substitution of Underwriters.

(i) If any Underwriter shall default in its obligation to purchase on any Closing Date the Shares agreed to be purchased hereunder on such Closing Date, the Representative shall have the right, within 36 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase such Shares on the terms contained herein. If, however, the Representative shall not have completed such arrangements within such 36 hour period, then the Company shall be entitled to a further period of 36 hours within which to procure another party or other parties satisfactory to the Underwriters to purchase such Shares on such terms. If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by the Representative and the Company as provided above, the aggregate number of Shares which remains unpurchased on such Closing Date does not exceed 10% of the aggregate number of all the Shares that all the Underwriters are obligated to purchase on such date, then the Company shall have the right to require each non-defaulting Underwriter to purchase the number of Shares which such Underwriter agreed to purchase hereunder at such date and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the number of Shares which such Underwriter agreed to purchase hereunder) of the Shares of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default. In any such case, either the Representative or the Company and the Selling Stockholders shall have the right to postpone the applicable Closing Date for a period of not more than seven days in order to effect any necessary changes and arrangements (including any necessary amendments or supplements to the Registration Statement or Prospectus or any other documents), and the Company agrees to file promptly any amendments to the Registration Statement or the Prospectus which in the opinion of the Company and the Underwriters and their counsel may thereby be made necessary.

(ii) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by the Representative and the Company as provided above, the aggregate number of such Shares which remains unpurchased exceeds 10% of the aggregate number of all the Shares to be purchased at such date, then this Agreement, or, with respect to a Closing Date which occurs after the first Closing Date, the obligations of the Underwriters to purchase and of the Company or the Selling Stockholders, as the case may be, to sell the Option Shares to be purchased and sold on such date, shall terminate, without liability on the part of any non-defaulting Underwriter to the Company or the Selling Stockholders, and without liability on the part of the Company or the Selling Stockholders, except as provided in Sections 6, 8 and 9. The provisions of this Section 10 shall not in any way affect the liability of any defaulting Underwriter to the Company arising out of such default. The term “Underwriter” as used in this Agreement shall include any person substituted under this Section 10 with like effect as if such person had originally been a party to this Agreement with respect to such Shares.

11. Notices. Notice given pursuant to any of the provisions of this Agreement shall be in writing and, unless otherwise specified, shall be mailed or delivered (i) if to the Company or the Selling Stockholders at the office of the Company, 5300 Bee Cave Road, Building I, Suite 100, Austin, Texas 78746, Attention: Robert A.

The respective agreements, covenants, indemnities and other statements set forth in Sections 7 and 9 hereof shall remain in full force and effect, regardless of any termination or cancellation of this Agreement.

13. Successors. This Agreement shall inure to the benefit of and shall be binding upon the Underwriters, the Company, the Selling Stockholders and their respective successors and legal representatives, and nothing expressed or mentioned in this Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement, or any provisions herein contained, this Agreement and all conditions and provisions hereof being intended to be and being for the sole and exclusive benefit of such persons and for the benefit of

15. Acknowledgement. The Company acknowledges and agrees that each of the Underwriters is acting solely in the capacity of an arm’s length contractual counterparty to the Company with respect to the offering of Shares contemplated hereby. Additionally, neither the Representative nor any of the other Underwriters is advising the Company or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Representative or Underwriter has advised or is advising the Company on other matters). The Company has conferred with its own advisors concerning such matters and shall be responsible for making its own independent investigation and appraisal of the transactions contemplated hereby, and the Underwriters shall have no responsibility or liability to the Company or any other person with respect thereto.
