In addition, the Company has granted to the Underwriters the option referred to in Section 2(d) hereof to purchase an aggregate of not more than an additional [ ] ([ ]) shares of Common Stock, if requested by the Underwriters in accordance with Section 2(d) hereof. It is understood that the Underwriters propose to offer the “Shares” (as hereinafter defined) to be purchased hereunder to the public upon the terms and conditions set forth in the “Registration Statement” (as defined below) after the “Effective Date” (as defined below) of the Registration Statement. As used in this Agreement, (a) the term “Firm Shares” shall mean the Common Stock to be issued and sold to the Underwriters at the “First Closing Date” (as defined in Section 2(b) below); (b) the term “Option Shares” shall mean any of the additional up to [ ] ([ ]) shares of Common Stock purchased pursuant to the option referred to in Section 2(d) hereof; and (c) the term “Shares” shall mean the Firm Shares and the Option Shares collectively.

As the representative of the Underwriters, ▇▇▇▇▇▇▇▇ Curhan Ford & Co. has informed the Company that ▇▇▇▇▇▇▇▇ Curhan Ford & Co. is authorized to enter into this Agreement on behalf of the several Underwriters, and that the several Underwriters are willing, on the basis of the representations, warranties and agreements of the Company herein contained, and upon the terms but subject to the conditions herein set forth, acting severally and not jointly, to purchase the number of Firm Shares set forth opposite their respective names in Schedule A hereto, plus their pro rata portion of the Option Shares if ▇▇▇▇▇▇▇▇ Curhan Ford & Co. elects to exercise the over-allotment option in whole or in part for the account of the several Underwriters.

As the representative of the Underwriters, ▇▇▇▇▇▇▇▇ Curhan Ford & Co. has also informed the Company that (i) the Underwriters have or will orally provide the pricing information set forth in Schedule B to prospective purchasers prior to confirming sales of the Shares, and (ii) each Underwriter has represented and agreed that, without the prior written consent of the Company and ▇▇▇▇▇▇▇▇ Curhan Ford & Co., it has not made and will not make any offer relating to the Shares that would constitute a free writing prospectus, and any such free writing prospectus, the use of which has been consented to by the Company and ▇▇▇▇▇▇▇▇ Curhan Ford & Co., is listed in Schedule B hereto.

The Company hereby confirms its agreements with respect to the purchase of the Shares by the Underwriters as follows:

1. Representations and Warranties of the Company. The Company hereby represents and warrants to, and agrees with, the Underwriters that, as of the Effective Date, the First Closing Date and each Option Closing Date (as defined below) (both of which are collectively referred to herein as the “Closing Date”):

(a) A registration statement on Form S-1 (File No. 333-145403) relating to the offering of the Shares has been prepared by the Company in conformity with the requirements of the Securities Act of 1933, as amended (the “Act”), and the rules and regulations of the United States Securities and Exchange Commission (the “Commission”) promulgated pursuant to the Act (the “Rules and Regulations”), and said registration statement has been filed with the Commission under the Act. Amendments to said registration statement have been similarly prepared and filed with the Commission covering the registration of the Shares under the Act including the related preliminary prospectus or preliminary prospectuses (each being hereinafter referred to as a “Preliminary Prospectus” as further defined below), each of which has been furnished to the Underwriters. Each Preliminary Prospectus was endorsed with the legend required by Item 501(b) of Regulation S-K. As used in this Agreement and unless the context indicates otherwise, the term “Registration Statement” refers to and means said registration statement, all exhibits, financial statements and schedules included therein and the Prospectus included therein, as finally amended and revised on or prior to the Effective Date (as defined below) and, in the event of any post-effective amendment thereto or if any abbreviated registration statement to register additional shares of Common Stock pursuant to Rule 462(b) under the Act (the “Rule 462(b) Registration Statement”) becomes effective prior to the Closing Date, shall also mean such registration statement as so amended or such Rule 462(b) Registration Statement, as the case may be, and shall also include any Rule 430A Information (as defined below) to be included in the Prospectus included therein at the Effective Date, as provided by Rule 430A. The term “Effective Date” shall mean each date and time that the Registration Statement, any post-effective amendment or amendments thereto and any Rule 462(b) Registration Statement became or becomes effective.

immediately prior to the Applicable Time; the term “Applicable Time” shall mean [ : ] New York time on the date of this Agreement [Note: insert the time which, or a time immediately prior to a time, the Shares are priced]; the term “Issuer Free Writing Prospectus” shall mean any “issuer free writing prospectus” as defined in Rule 433 under the Act; the term “Rule 430A Information” shall mean information with respect to the Shares and the offering thereof permitted to be omitted from the Registration Statement when it becomes effective pursuant to Rule 430A; and, the term “Prospectus” refers to and means the prospectus relating to the Shares that is first filed pursuant to Rule 424(b) or, if no filing pursuant to Rule 424(b) is required, shall mean the form of final prospectus relating to the Shares included in the Registration Statement at the Effective Date. If the Registration Statement is amended or such Prospectus is supplemented after the Effective Date and prior to the Option Closing Date, then the terms “Registration Statement” and “Prospectus” shall include such documents as so amended or supplemented. Each Preliminary Prospectus and the Prospectus delivered to the Underwriters for use in connection with the offer and sale of the Shares was identical to the electronic version filed with the Commission via ▇▇▇▇▇, except to the extent permitted by Regulation S-T.

(b) (i) The Pricing Prospectus, as supplemented by any Issuer Free Writing Prospectus, other documents and pricing information listed in Schedule B hereto, taken together (collectively, the “Pricing 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 light of the circumstances under which they were made, not misleading, (ii) each Issuer Free Writing Prospectus listed in Schedule B hereto does not conflict with the information contained in the Registration Statement, the Pricing Prospectus or the Prospectus, and (iii) each such Issuer Free Writing Prospectus, as supplemented by and taken together with the Pricing 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 light of the circumstances under which they were made, not misleading; provided, however, that the foregoing representations and warranties shall not apply to statements or omissions made in the Pricing Prospectus or in an Issuer Free Writing Prospectus in reliance upon and conformity with written information furnished to the Company through ▇▇▇▇▇▇▇▇ Curhan Ford & Co. by or on behalf of any Underwriter expressly for inclusion therein. Each of the Registration Statement, any Rule 462(b) Registration Statement and any post-effective amendment to the Registration Statement or the Rule 462(b) Registration Statement, as the case may be, at the time it became effective and at all subsequent times through the Closing Date, complied and will comply in all material respects with the Act and the applicable Rules and Regulations and did not and will not contain any 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. Each Preliminary Prospectus, as of its date, and the Prospectus, as amended or supplemented, as of its date and at all subsequent times through the Closing Date, did not and will not contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The representations and warranties set forth in this Section 1(b) do not apply to statements in or omissions from the Registration Statement, any Rule 462(b) Registration Statement, or any post-effective amendment to the Registration Statement or the Rule 462(b) Registration Statement, as the case may be, or the Prospectus, or any amendments or supplements thereto, made in reliance upon and in conformity with information furnished to the Company in writing through ▇▇▇▇▇▇▇▇ Curhan Ford & Co. by or on behalf of any of the Underwriters expressly for inclusion therein.

(d) Neither the Commission nor any state regulatory authority has issued an order preventing or suspending the use of any Registration Statement or Preliminary Prospectus nor has the Commission or any such authority instituted or, to the Knowledge of the Company (as defined below), threatened to institute any proceedings with respect to such an order. When representations or warranties in this Agreement are qualified to the “Knowledge of the Company” or “Company’s Knowledge,” they are given by the Company to the extent of and qualified in all respects by the facts actually known to any of the executive officers or directors of the Company, with an obligation of reasonable inquiry on the part of such executive officers and directors, prior to the date such representations or warranties are made.

(e) The Company has delivered to the Underwriters one complete conformed copy of the Registration Statement and of each consent and certificate of experts filed as a part thereof, and conformed copies of the Registration Statement (without exhibits) and Preliminary Prospectus, any Issuer Free Writing Prospectus and the Prospectus, as amended or supplemented, in such quantities and at such places as the Underwriters have reasonably requested.

(f) The Company has not distributed and will not distribute, prior to the later of the Option Closing Date and the completion of the Underwriters’ distribution of the Shares, any offering material in connection with the offering and sale of the Shares other than a Preliminary Prospectus, the Prospectus, the Registration Statement or, following receipt of written consent of ▇▇▇▇▇▇▇▇ Curhan Ford & Co., which shall not be unreasonably withheld or delayed, any Issuer Free Writing Prospectus.

(g) This Agreement has been duly authorized, executed and delivered by, and assuming due authorization, execution and delivery by the other parties hereto, is a valid and binding agreement of, the Company, enforceable against the Company in accordance with its terms, except as rights to indemnification and contribution hereunder may be limited by applicable law and except as the enforcement hereof may be limited by bankruptcy, insolvency, reorganization, moratorium or other similar laws relating to or affecting the rights and remedies of creditors or by general equitable principles. All corporate action and approvals (including by the stockholders and other security holders of the Company) necessary for the Company to consummate the transactions contemplated in this Agreement have been obtained and are in effect. Stockholder approval of the transactions contemplated in this Agreement is not required under the rules of NASDAQ.

(h) The Company has been duly incorporated and is now, and at the Closing Date will be, validly existing as a corporation and in good standing under the laws of the States of Delaware, California and New Jersey and is not otherwise required to be qualified under the laws of any other jurisdiction, and has the corporate power and authority (i) to own or lease, as the case may be, its properties, whether tangible or intangible, and conduct its business as presently conducted and as described in the Pricing Prospectus (the “Business”) and (ii) to execute, deliver and perform this Agreement and consummate the transactions contemplated hereby and thereby. The Company has no subsidiaries other than those subsidiaries set forth on Exhibit 21.1 of the Registration Statement (each, a “Subsidiary” and collectively, the “Subsidiaries”). The Company has no subsidiaries that are “significant subsidiaries,” other than NTI-Empire, Inc., a Delaware corporation; for purposes of this Section 1(h) a “significant subsidiary” shall be deemed to include a subsidiary in which (i) the assets of the subsidiary exceed 5% of the total assets of the Company and its subsidiaries on a consolidated basis, (ii) the revenues of the subsidiary for the most recently completed fiscal year exceed 5% of the total revenues of the Company and its subsidiaries on a consolidated basis for the most recently completed fiscal year or (iii) the number of employees of the subsidiary exceed 5% of the total number of employees of the Company and its subsidiaries on a consolidated basis.

Each of the Company and its Subsidiaries is duly qualified as a foreign corporation to transact business and is in good standing in each jurisdiction in which the nature of the business transacted by it or the character or location of its properties, in each case taken as a whole, makes such qualification necessary, except where the failure to so qualify or be in good standing would not reasonably be expected to have a material adverse effect upon the condition (financial or otherwise), results of operations, prospects, income, stockholders’ equity, net worth, business, assets or properties of the Company and the Subsidiaries, taken as a whole (a “Material Adverse Effect”). The Company owns, directly or indirectly, all of the issued and outstanding shares of capital stock or other equity and ownership and/or voting interests of each of the Subsidiaries, free and clear of any security interests, liens, encumbrances, claims and charges other than as disclosed in the Registration Statement and the Pricing Prospectus, and all of such shares or other interests have been duly authorized and validly issued and are fully paid and non-assessable. There are no options or warrants for the purchase of, or other rights to purchase or acquire, or outstanding securities convertible into or exchangeable for, any capital stock or other securities or interests of the Subsidiaries.

(i) The consolidated financial statements of the Company and the financial statements of its Subsidiaries, including the financial statement schedules and related notes, filed with the Commission as part of the Registration Statement and included in the Pricing Prospectus are correct in all material respects and fairly present the financial position of the Company and its Subsidiaries, or that of the applicable Subsidiary, as the case may be, as of and at the respective dates thereof and the results of operations and cash flows of the Company or that of the applicable Subsidiary, as the case may be, for the respective periods indicated therein and comply as to form in all material respects with the applicable accounting requirements included in Regulations S-K and S-X, as well as any other applicable rules and regulations. Such financial statements have been prepared in accordance with the generally accepted accounting principles of the United States (“GAAP”) applied on a consistent basis throughout the periods involved, except as otherwise stated in the Registration Statement and the Pricing Prospectus; provided, however, that financial statements that are unaudited are subject to year-end adjustments and do not contain footnotes required under GAAP. The selected consolidated financial data set forth in the Registration Statement and the Pricing Prospectus fairly present the information shown therein at the respective dates thereof and for the respective periods covered thereby and have been presented on a basis consistent with that of the audited and unaudited financial statements included in the Registration Statement and the Pricing Prospectus.

Except as described in the Pricing Disclosure Package, no party to any such contract has given notice to the Company or any Subsidiary of the cancellation of or, to the Knowledge of the Company, has threatened to cancel, any such contract, and except as described in the Registration Statement and Pricing Prospectus, neither the Company nor any Subsidiary is in default thereunder. Except as described in the Registration Statement and the Pricing Prospectus, there is no voting or other stockholder agreement between the Company and any of its stockholders or, to the Knowledge of the Company, between or by and among any stockholders of the Company. There are and, as of the Closing Date, there will be, no loans to the Company from any officers, directors, 5% or greater securityholders or consultants, or any affiliates thereof, except as described in the Registration Statement and Pricing Prospectus.

(o) The Company and the Subsidiaries do not own any real property. Each of the Company and the Subsidiaries has good title to all of its personal property (tangible and intangible) and assets reflected as owned in the financial statements referred to in Section 1(i) above, including any licenses, trademarks and copyrights, described in the Registration Statement and Pricing Prospectus as owned by it, free and clear of all security interests, liens, charges, mortgages, encumbrances and restrictions other than (i) as disclosed in the Registration Statement and the Pricing Prospectus and (ii) such other security interests, liens, charges, mortgages, encumbrances and restrictions that do not materially affect the value of such property or materially interfere with the use made or proposed to be made of such property by the Company or its Subsidiaries. The leases, subleases and licenses under which the Company or a

Subsidiary is entitled to lease, hold or use any real or personal property, are valid and enforceable by the Company and the Subsidiaries, all rentals, royalties or other payments accruing thereunder which became due prior to the date of this Agreement have been duly paid and none of the Company, any Subsidiary, or, to the Knowledge of the Company, any other party, is in default in respect of any of the terms or provisions of any such leases, subleases and licenses and no claim of any sort has been asserted by anyone against the Company or any Subsidiary under any such leases, subleases or licenses affecting or questioning the rights of the Company or any Subsidiary to the continued use or enjoyment of the rights and property covered thereby. Neither the Company nor any Subsidiary has received notice of any violation of any applicable law, ordinance, regulation, order or requirement relating to its owned or leased properties, except for any such violation that would not reasonably be expected to result in a Material Adverse Effect. Each of the Company and each Subsidiary owns or leases all such properties as are necessary to its operations as now conducted and as proposed to be conducted as set forth in the Registration Statement and Prospectus.

(p) Each of the Company and its Subsidiaries has filed with the appropriate federal, state and local governmental agencies, and all appropriate foreign countries and political subdivisions thereof, all tax returns, including franchise tax returns, which are required to be filed by it or has duly obtained extensions of time for the filing thereof and has paid all taxes required to be paid by it as shown on such returns and all other material assessments against it, to the extent that the same have become due and are not being contested in good faith; and the provisions for income taxes payable, if any, shown on the financial statements filed with or as part of the Registration Statement and the Pricing Prospectus are sufficient for all accrued and unpaid foreign and domestic taxes, whether or not disputed, and for all periods to and including the dates of such consolidated financial statements. None of the Company nor any Subsidiary has executed or filed with any taxing authority, foreign or domestic, any agreement extending the period for assessment or collection of any income taxes and, to the Knowledge of the Company, is not a party to any pending action or proceeding by any foreign or domestic governmental agency for assessment or collection of taxes; and no claims for assessment or collection of taxes have been asserted in writing against the Company. To the Company’s Knowledge, there is no material tax deficiency that has been or might be asserted or threatened against the Company or its Subsidiaries.

(q) Each of the Company and its Subsidiaries are insured by recognized, financially sound and reputable institutions with policies in such amounts, with such deductibles and covering such risks as reasonably adequate and customary, in the Company’s judgment, for their businesses including, but not limited to, policies covering real and personal property owned or leased by the Company and its Subsidiaries against theft, damage, destruction, acts of vandalism, general liability and directors and officers liability. The Company believes that it or any Subsidiary will be able (i) to renew its existing insurance coverage as and when such policies expire or (ii) to obtain comparable coverage from similar institutions as may be necessary or appropriate to conduct its business as now conducted without incurring a material additional cost to the Company. Neither the Company nor any Subsidiary has been denied any insurance coverage which it has sought or for which it has applied. To the Knowledge of the Company, there are no facts or circumstances which would require it or a Subsidiary to notify its insurers of any material claim of which notice has not been made or will not be made in a timely manner. To the Knowledge of the Company, there are no facts or circumstances under any of its or any Subsidiary’s existing insurance policies which would relieve any insurer of its obligation to satisfy in full any existing valid claim of the Company or a Subsidiary under any such policies.

(r) Except as disclosed in the Registration Statement and the Pricing Prospectus, each of the Company and its Subsidiaries owns or otherwise possesses adequate, and to the Knowledge of the Company, enforceable, and unrestricted rights to use all patents, patent applications, patent rights, licenses, inventions, collaborative research agreements, trade secrets, know-how, trademarks, trademark registrations, service marks, service ▇▇▇▇ registrations, trade names, copyrights, works of authorship, formulae, customer lists, designs, technical data and other proprietary rights and intellectual property (including other unpatented and/or unpatentable proprietary or confidential information, systems or procedures) which are necessary to or used in the conduct of its businesses as now conducted or as proposed to be conducted as described in the Registration Statement and Pricing Prospectus (collectively, the “Intellectual Property”).

(y) The issuance and sale of the Shares to be purchased by the Underwriters from the Company have been duly authorized and, upon delivery against payment therefor as contemplated by this Agreement, will be validly issued, fully paid and non-assessable and will conform to the description of the Shares contained in the Pricing Prospectus.

(cc) The confidentiality agreements between the Company or the Subsidiaries and their officers, employees and consultants are binding and enforceable obligations upon the other parties thereto in accordance with their terms, except to the extent enforceability may be limited by any applicable bankruptcy, insolvency, reorganization, fraudulent conveyance, moratorium or similar laws affecting creditors’ rights generally and to the extent that the remedy of specific performance and injunction or other forms of equitable relief may be subject to equitable defenses and the discretion of the court before which any proceeding therefor may be brought.

(dd) Except as set forth in the Registration Statement and Pricing Prospectus, none of the Company or any Subsidiary has employee benefit plans (including, without limitation, profit sharing and welfare benefit plans) or deferred compensation arrangements that are subject to the provisions of the United States Employee Retirement Income Security Act of 1974 (“ERISA”).

(ee) The Company has filed registration statements on Form 8-A with respect to its Common Stock and its Series RP Preferred Stock under Sections 12(b) or 12(g) of the 1934 Act and such registration statements have been declared effective by the Commission. The Common Stock of the Company is registered and listed on The NASDAQ Capital Market under the ticker symbol “NTII” or “NTIID.” The Company has not received any notice that it is not in compliance with the listing or maintenance requirements of NASDAQ, expect for any notice that has been cured or that has been disclosed in the Registration Statement or Pricing Prospectus. Upon receipt of the proceeds on the First Closing Date from the sale of the Firm Shares to the Underwriters pursuant to this Agreement, the Company believes that it will be, and has no reason to believe that it will not in the foreseeable future continue to be, in compliance with such listing and maintenance requirements. The Company has taken no action designed to, or likely to have the effect of, terminating the registration of the Common Stock or the Series RP Preferred Stock under the 1934 Act, nor has the Company received any notification that the Commission or NASDAQ is contemplating terminating such registrations or listing.

(gg) The Company has provided or made available to Underwriters’ Counsel, complete and accurate copies of all agreements, certificates, correspondence and other items, documents and information requested by such counsel, including in such counsel’s due diligence request of July 25, 2007.

(hh) The Company’s board of directors has validly appointed an audit committee whose composition satisfies the requirements of the 1934 Act and the rules and regulations of the Commission adopted thereunder, and Rules 4200 and 4350 of the rules of NASDAQ. The Company’s audit committee has adopted a charter that satisfies the 1934 Act and the rules and regulations of the Commission adopted thereunder, and Rules 4200 and 4350 of NASDAQ.

(ii) The Company and each of its Subsidiaries maintain a system of internal control over financial reporting (as such term is defined in Rule 13a-15(f) under the ▇▇▇▇ ▇▇▇) that complies with the requirements of the 1934 Act and has been designed by the Company’s principal executive officer and principal financial officer, or under their supervision, to provide reasonable assurance that (i) transactions are executed in accordance with management’s general or specific authorizations; (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP and to maintain asset accountability; (iii) access to assets is permitted only in accordance with management’s general or specific authorization; and (iv) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences.

Since

the date of the latest audited financial statements of the Company included in or incorporated by reference into the Pricing Prospectus, there has been no change in the Company’s internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

(jj) The Company has taken all necessary actions to ensure that, upon and at all times after effectiveness of the Registration Statement, it has established and maintains disclosure controls and procedures (as such term is defined in Rule 13a-15(e) and 15d-15(e) under the ▇▇▇▇ ▇▇▇) that: (A) are designed to ensure that material information relating to the Company, including its consolidated subsidiaries, is made known to the Company’s principal executive officer and its principal financial officer by others within those entities, particularly during the periods in which the periodic reports required under the 1934 Act will be prepared; and (B) are effective to perform the functions for which they are established. Since the date of the Company’s most recent audited fiscal year, there has been no change in the Company’s internal controls that has materially affected, or is reasonably likely to materially affect, the Company’s internal controls, including any corrective actions with regard to significant deficiencies and material weaknesses.

(kk) The Company is in material compliance with all provisions of the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act of 2002 and the rules and regulations promulgated by the Commission thereunder that are applicable, or will be applicable as of the date of payment for and delivery of the Firm Shares and Option Shares pursuant hereto, to the Company.

(nn) There are no material off-balance sheet arrangements (as defined in Item 303 of Regulation S-K).

(oo) Any certificate signed by an officer of the Company in his capacity as such and delivered to the Underwriters or Underwriters’ Counsel pursuant to this Agreement shall be deemed a representation and warranty by the Company to the Underwriters as to the matters set forth in such certificate.

(pp) The issue and sale of the Shares, the compliance by the Company with this Agreement, the consummation of the transactions herein contemplated and the transactions entered into in connection with the Securities Purchase Agreement dated as of September 12, 2007 by and among the Company and certain purchasers (the “Platinum Bridge”) will not conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under (i) any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound or to which any of the property or assets of the Company or any of its Subsidiaries is subject; (ii) any agreement, including without limitation the Securities Purchase Agreement dated as of March 30, 2007 among the Company and certain purchasers, under which the Company has granted registration rights or participation rights; (iii) the provisions of the Certificate of Incorporation or By-laws of the Company; or (iv) any statute or any order, rule or regulation of any court or governmental agency or body having jurisdiction over the Company or any of its Subsidiaries or any of their properties.

(rr) The Company and the Subsidiaries have complied with, are not in material violation of, and have not received any written notices of violation with respect to, any statutes, rules, or regulations applicable to the ownership, testing, development, manufacture, packaging, processing, use, distribution, marketing, labeling, promotion, sale, offer for sale, reimbursement, storage, import, export or disposal of any product manufactured or distributed by the Company or the Subsidiaries (“Applicable Laws”), or any license, certificate, approval, clearance, authorization, permit, supplement or amendment required by any Applicable Laws (“Authorizations”). The Company and the Subsidiaries possess all material Authorizations and such material Authorizations are in full force and effect. The Company and the Subsidiaries are, and their products are, in compliance in all material respects with all Authorizations and Applicable Laws, including, but not limited to, all laws, statutes, rules, regulations, or orders administered, issued or enforced by the Federal Food and Drug Administration (the “FDA”) or any other federal or foreign governmental authority having authority over the Company or any of its products (“Governmental Authority”). The Company or the Subsidiaries have not received from the FDA or any other Governmental Authority any notice of adverse findings, regulatory letters, notices of violations, Warning Letters, criminal proceeding notices under Section 305 of the U.S. Federal Food, Drug, and Cosmetic Act, or other similar communication from the FDA alleging or asserting material noncompliance with Applicable Laws or any Authorizations, and there have been no seizures conducted or, to the Knowledge of the Company, threatened by the FDA, and no recalls, market withdrawals, field notifications, notifications of misbranding or adulteration, safety alerts or similar actions relating to the safety or efficacy of the Company’s or the Subsidiaries’ products conducted, requested or threatened by the FDA or other Governmental Authority relating to the products sold by the Company or the Subsidiaries.

Except as described in the Prospectus and the Registration Statement, the Company and the Subsidiaries have not, either voluntarily or involuntarily, initiated, conducted, or issued or caused to be initiated, conducted or issued, any recall, market withdrawal, safety alert, “dear doctor” letter, or other similar notice or action relating to the alleged lack of safety or efficacy of any of the Company’s or Subsidiaries’ products or any alleged product defect or violation, and to the Knowledge of the Company, no Governmental Authority has initiated, conducted or intends to initiate any such notice or action. The Company and the Subsidiaries have not received notice of any claim, action, suit, proceeding, hearing, enforcement, investigation, arbitration or other similar action from any Governmental Authority alleging that any product operation or activity is in material violation of any Applicable Laws or Authorizations and, to the Knowledge of the Company, no such Governmental Authority is considering any such claim, litigation, arbitration, action, suit, investigation or proceeding. Each regulatory submission for the Company’s or the Subsidiaries’ products has been filed, cleared, approved and maintained in compliance in all material respects with all Applicable Laws and Authorizations, including without limitation applicable federal statutes, rules, regulations or orders administered or promulgated by the FDA, and all laboratory and clinical studies, and tests that support clearance or approval of its products have been conducted in all material respects in compliance with accepted professional scientific standards and all Applicable Laws and Authorizations in all material respects. No filing or submission to the FDA or any other Governmental Authority, intended to be the basis for any Authorization, contains any material omission or material false information, and neither the Company nor the Subsidiaries have received any notices or correspondence from any Governmental Authority (including, but not limited to, the FDA) requiring suspension of any studies, tests, or clinical trials conducted by or on behalf of the Company. To the Knowledge of the Company, there are no facts which are reasonably likely to cause (A) the withdrawal, or recall of any products sold or intended to be sold by the Company or the Subsidiaries, (B) a change in the marketing classification or labeling of any such products, (C) a termination or suspension of marketing clearance of any such products, or (D) a suspension or revocation of any of the Company’s or Subsidiaries Authorizations. The Company or the Subsidiaries have not received notice (whether complete or pending) of any proceeding seeking recall, suspension or seizure of any products sold or intended to be sold by the Company or the Subsidiaries.

(ss) The studies, tests and preclinical and clinical trials conducted by or on behalf of the Company or the Subsidiaries were and, if still pending, are, in all material respects, being conducted in accordance with experimental protocols, procedures and controls pursuant to accepted professional scientific standards and all Applicable Laws and Authorizations, including, without limitation, the Federal Food, Drug and Cosmetic Act and implementing regulations at 21 C.F.R. Parts 50, 54, 56 and 58; the descriptions of the results of such studies, tests and trials contained in the Registration Statement and the Pricing Prospectus are accurate and complete in all material respects and fairly present the data derived from such studies, tests and trials; except to the extent disclosed in the Registration Statement and the Pricing Prospectus, the Company and the Subsidiaries are not aware of any studies, tests or trials the results of which the Company or the Subsidiaries believe reasonably call into question the study, test, or trial results described or referred to in the Registration Statement and the Pricing Prospectus when viewed in the context in which such results are described and the clinical state of development, and the Company and the Subsidiaries have not received any notices or correspondence from any Governmental Authority requiring the termination, suspension or material modification of any studies, tests or preclinical or clinical trials conducted by or on behalf of the Company or the Subsidiaries.

(tt) The Company (A) is in compliance, in all material respects, with any and all applicable foreign, federal, state and local laws, rules, regulations, treaties, statutes and codes promulgated by any and all governmental authorities (including pursuant to the Occupational Health and Safety Act) relating to the protection of human health and safety in the workplace (“Occupational Laws”); (B) has received all material permits, licenses or other approvals required of it under applicable Occupational Laws to conduct its business as currently conducted; and (C) is in compliance, in all material respects, with all terms and conditions of such permit, license or approval. No action, proceeding, revocation proceeding, writ, injunction or claim is pending or, to the Company’s Knowledge, threatened against the Company relating to Occupational Laws, and to the Company’s Knowledge there are no facts, circumstances or developments relating to its operations or cost accounting practices that could reasonably be expected to form the basis for or give rise to such actions, suits, investigations or proceedings.

(uu) Except as set forth in the Registration Statement and the Pricing Prospectus, other than in the ordinary course of business in conducting clinical trials, the Company has not granted rights to develop, manufacture, produce, assemble, distribute, license, market or sell its products to any other person and is not bound by any agreement that affects the Company’s exclusive right to develop, manufacture, produce, assemble, distribute, license, market or sell its products.

(vv) The Company previously engaged each of Scimitar Equity Research (“Scimitar”) and ▇▇▇▇▇▇ Associates (“▇▇▇▇▇▇” and together with Scimitar, the “Research Firms”) to initiate research coverage of the Company and has paid each of the Research Firms a fee for the issuance of research reports (the “Research Reports”). Other than the Company’s payments to the Research Firms, the Research Reports are independently produced and the Company does not endorse the contents of the Research Reports. The Company has not participated in the preparation of the Research Reports and has not provided any information to the Research Firms regarding the Company, other than indirectly through the Company’s filing of periodic reports with the Commission. The valuation estimates for the Company’s stock and underlying estimates for potential market size, future revenues and other forward-looking information have been prepared entirely by the Research Firms. The Company has not prepared any such estimates of its own and has not reviewed the estimates of the Research Firms. Accordingly, the Company does not endorse the estimates of the Research Firms or any other aspect of these Research Reports.

(ww) Nothing has come to the attention of the Company that has caused the Company to believe that the statistical and market-related data included in the Registration Statement and the Pricing Prospectus is not based on or derived from sources that are reliable and accurate in all material respects.

2. Purchase, Delivery and Sale of the Shares.

(a) Upon the basis of the representations and warranties of ▇▇▇▇▇▇▇▇ Curhan Ford & Co. herein contained, and subject to the terms and conditions herein set forth, the Company agrees to issue and sell to the several Underwriters the respective number of Firm Shares set forth opposite the name of such Underwriter in Schedule A hereto. On the basis of the representations, warranties and agreements of the Company herein contained, and upon the terms but subject to the conditions herein set forth, the Underwriters agree, severally and not jointly, to purchase from the Company the respective number of Firm Shares set forth opposite their names on Schedule A, subject to adjustment in accordance with Section 8 hereof. The purchase price per Share to be paid by the several Underwriters to the Company shall be U.S.$[ ] per share.

Payment for the Firm Shares to be sold by the Company shall be made at the First Closing Date (and, in the case of the Option Shares, if applicable, at the Option Closing Date) by wire transfer of immediately available funds to the order of the Company.

(b) Delivery by the Company of the Firm Shares to be purchased by the Underwriters and payment therefor by the Underwriters shall be made by the Company and the Underwriters at 9:00 a.m. New York time, at the offices of ▇▇▇▇▇▇▇ Procter LLP, ▇▇▇▇ ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇ (the “▇▇▇▇▇▇▇ Office”), or at such other place as may be agreed upon among the Underwriters and the Company, on the third (3rd) full business day following the date of this Agreement, or, if this Agreement is executed and delivered after 4:30 P.M., New York time, on the fourth (4th) full business day following the date of this Agreement, or at such other time and date not later than seven (7) full business days following the first day that Shares are traded as the Underwriters and the Company may determine (or at such time and date to which payment and delivery shall have been postponed pursuant to this Section 2), such time and date of payment and delivery being herein called the “First Closing Date”; provided, however, that if the Company has not made available to the Underwriters copies of the Prospectus within the time provided in this Agreement, the Underwriters may, in their sole discretion, postpone the Closing Date until no later than two (2) full business days following delivery of copies of the Prospectus to the Underwriters.

(c) The Company shall deliver, or cause to be delivered, a credit representing the Firm Shares to an account or accounts at The Depository Trust Company (“DTC”) for the accounts of the Underwriters at the First Closing Date, against the irrevocable release of a wire transfer of immediately available funds for the amount of the purchase price therefor. The Company shall also deliver, or cause to be delivered, a credit representing the Option Shares to an account or accounts at DTC for the accounts of the Underwriters, at the First Closing Date or the Option Closing Date, as the case may be, against the irrevocable release of a wire transfer of immediately available funds for the amount of the purchase price therefor. Time shall be of the essence, and delivery at the time and place specified in this Agreement is a further condition to the obligations of the Underwriters. Not later than 12:00 noon, New York time, on the second business day following the date the Shares are released by the Underwriters for sale to the public, the Company shall deliver or cause to be delivered copies of the Prospectus in such quantities and at such places as the Underwriters shall request.

(d) Subject to the terms and conditions of this Agreement, and on the basis of the representations, warranties and agreements contained herein, for the purposes of covering any over-allotments in connection with the distribution and sale of the Firm Shares as described in the Registration Statement and Pricing Prospectus, the Underwriters are hereby granted an option to purchase all or any part of the Option Shares from the Company. The purchase price to be paid per share for the Option Shares will be the same price as the price per Firm Share set forth in Section 2(a) hereof. The option granted hereby may be exercised by notice from the Underwriters to the Company in accordance with Section 2(e) hereof solely by the Underwriters as to all or any part of the Option Shares at any time within thirty (30) days after the Effective Date. The Underwriters will not be under any obligation to purchase any Option Shares prior to the exercise by the Underwriters of such option in accordance with Section 2(e) hereof.

(e) The option granted pursuant to Section 2(d) hereof may be exercised by ▇▇▇▇▇▇▇▇ Curhan Ford & Co. by giving notice to the Company, which must be confirmed by a letter or facsimile setting forth the number of Option Shares to be purchased by the Underwriters, the date and time for delivery of and payment for the Option Shares to be purchased and stating that the Option Shares referred to therein are to be used for the sole purpose of covering over-allotments in connection with the distribution and sale of the Firm Shares by the Underwriters. If such notice is given prior to the First Closing Date, the date set forth therein for such delivery and payment will be the First Closing Date. If such notice is given on or after the First Closing Date, the date set forth therein for such delivery and payment will not be earlier than two (2) full business days thereafter and not more than five (5) full business days after the date of such notice. The date and time set forth in such notice is herein called the “Option Closing Date.” Upon exercise of such option, through the Underwriters’ delivery of the aforementioned notice, the Company will become obligated to sell to the Underwriters, and, subject to the terms and conditions set forth in this Section 2(e), the Underwriters will become obligated to purchase, the number of Option Shares specified in such notice. If any Option Shares are to be purchased, (i) each Underwriter agrees, severally and not jointly, to purchase the number of Option Shares (subject to such adjustments to eliminate fractional shares as the Underwriters may determine) that bears the same proportion to the total number of Option Shares to be purchased as the number of Firm Shares set forth on Schedule A opposite the name of such Underwriter bears to the total number of Firm Shares, subject to any adjustment in accordance with Section 8 hereof and (ii) the Company agrees to sell such number of Option Shares. The Underwriters may cancel the option at any time prior to its expiration by giving written notice of such cancellation to the Company.

(f) Payment for any Option Shares purchased will be made to the Company by wire transfer in immediately-available funds to the order of the Company, against delivery of the Option Shares purchased by the Underwriters at the ▇▇▇▇▇▇▇ Office (or at such other location as the Underwriters and the Company may agree).

(g) The parties will use their best efforts to make the offering of the Shares “DTC eligible” and to comply with the procedures thereof. In the event that the Underwriters determine not to utilize DTC, the Company will make the certificates for the Shares to be purchased by the Underwriters hereunder available to the Underwriters for inspection, checking and packaging at the office of the Company’s transfer agent or correspondent in San Francisco, CA, not less than one (1) full business day prior to the First Closing Date and the Option Closing

Date, as the case may be. The certificates representing the Shares shall be in such names and denominations as the Underwriters may request at least two (2) full business days prior to the respective Closing Date.

3. Public Offering by the Underwriters. The Underwriters agree to cause the Shares to be offered to the public initially at the price and under the terms set forth in the Registration Statement and Prospectus as soon, on or after the effective date of this Agreement, as the Underwriters deem advisable, but no more than five (5) full business days after such effective date. The Company is advised by the Underwriters that the Shares are to be offered to the public initially at U.S.$[ ] a share (the “Public Offering Price”).

4. Agreements of the Company. The Company covenants and agrees with the Underwriters that:

(a) If the Registration Statement has not been declared effective prior to the time of execution of this Agreement, the Company will use its best efforts to cause the Registration Statement to become effective as promptly as possible, or, if the procedure in Rule 430A of the Act is followed, to prepare and timely file with the Commission under Rule 424(b) under the Act a Prospectus in a form approved by the Underwriters containing information previously omitted at the time of effectiveness of the Registration Statement in reliance on Rule 430A of the Act, and will not at any time, whether before or after the Effective Date, file any amendment or supplement to the Registration Statement, (i) which shall not have been previously submitted to, and approved by, the Underwriters or Underwriters’ Counsel within a reasonable time prior to the filing thereof, (ii) to which the Underwriters or Underwriters’ Counsel shall have reasonably objected as not being in compliance with the Act or the Rules and Regulations or (iii) which is not in compliance with the Act or the Rules and Regulations. If the Company elects to rely on Rule 462(b) under the Act, the Company shall file a Rule 462(b) Registration Statement with the Commission in compliance with Rule 462(b) under the Act prior to the time confirmations are sent or given, as specified by Rule 462(b)(2) under the Act, and shall pay the applicable fees in accordance with Rule 111 under the Act. The Company further agrees to file promptly all material required to be filed by the Company with the Commission pursuant to Rule 433(d) under the Act.

(b) The Company will, promptly after it shall have received notice, notify the Underwriters (i) of the receipt of any comments on, or requests for amendment of, the Registration Statement, for supplement of the Prospectus, or for additional or supplemental information, by or from the Commission, and (ii) of the time and date when the Registration Statement or any post-effective amendment thereto has become effective or any supplement to the Prospectus has been filed.

(c) The Company will advise the Underwriters promptly of any request of the Commission for an amendment or supplement to the Registration Statement or the Prospectus, or for any additional information, or of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement, or of any judgment, order, injunction or decree preventing or suspending the use of any Preliminary Prospectus or the Prospectus, or of the institution of any proceedings for any of such purposes, of which it has Knowledge, and will use its best efforts to prevent the issuance of any stop order, and, if issued, to obtain as promptly as possible the lifting thereof.

(d) If at any time when a Prospectus relating to the Shares is required, in the opinion of Underwriters’ Counsel, to be delivered under the Act by the Underwriters (the “Prospectus Delivery Period”), any event shall have occurred as a result of which, in the reasonable opinion of counsel for the Company or Underwriters’ Counsel, the Prospectus, as then amended or supplemented, includes an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made when the Prospectus is delivered, not misleading, or if it is necessary at any time to amend the Prospectus to comply with the Act, the Company will notify the Underwriters promptly and, at the request of ▇▇▇▇▇▇▇▇ Curhan Ford & Co., prepare and file with the Commission an appropriate amendment or supplement in accordance with Section 10 of the Act, which will correct such statement or omission, or effect such compliance, each such amendment or supplement to be reasonably satisfactory to Underwriters’ Counsel, and the Company will furnish to the Underwriters copies of such amendment or supplement as soon as available and in such quantities as the Underwriters may reasonably request, provided that, if any Underwriter is required to deliver a Prospectus in connection with sales of Shares at any time more than nine (9) months after the date hereof, all costs and expenses in connection with the furnishing of copies of such amended or supplemented Prospectus will be at the expense of such Underwriter.

(e) Within the Prospectus Delivery Period, or pursuant to the undertakings of the Company in the Registration Statement, the Company, at its own expense, will comply in all material respects with all requirements imposed upon it by the Act, the Rules and Regulations, the 1934 Act and the rules and regulations of the Commission promulgated under the 1934 Act, each as now or hereafter amended or supplemented, and by any order of the Commission so far as necessary to permit the continuance of sales of, or dealings in, the Shares.

(f) The Company will furnish to the Underwriters, without charge, a signed copy of the Registration Statement and of any amendment or supplement thereto which has been filed prior to the date of this Agreement, together with each exhibit filed therewith, and three (3) conformed copies of such Registration Statement and as many amendments thereto (unsigned and exclusive of exhibits) as the Underwriters may reasonably request. The signed copies of the Registration Statement so furnished to the Underwriters will include signed copies of any and all consents and reports of the independent public auditors as to the financial statements included in the Registration Statement and Pricing Prospectus, and signed copies of any and all consents and certificates of any other person whose profession gives authority to statements made by them and who are named in the Registration Statement or Pricing Prospectus as having prepared, certified or reviewed any parts thereof.

(g) The Company will deliver to the Underwriters, without charge, (i) prior to the Effective Date, copies of each Preliminary Prospectus filed with the Commission bearing in red ink the statement required by Item 501 of Regulation S-K of the Rules and Regulations; (ii) on and from time to time after the Effective Date, copies of the Prospectus; and (iii) as soon as they are available, and from time to time thereafter, copies of each amended or supplemented Prospectus, and the number of copies to be delivered in each such case will be such as the

Underwriters may reasonably request. The Company has consented and hereby consents to the use of each Preliminary Prospectus for the purposes permitted by the Act and the Rules and Regulations. The Company authorizes the Underwriters to use the Prospectus in connection with the sale of the Shares during the Prospectus Delivery Period. Notwithstanding the foregoing, the Underwriters shall not use any Preliminary Prospectus or the Prospectus if the Company has given the Underwriters written notice of the occurrence, or imminently potential occurrence, of any development that could cause such Preliminary Prospectus or Prospectus, as the case may be, to include an untrue statement of a material fact or to omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances, not misleading.

(h) The Company shall promptly from time to time take such action as the Underwriters may reasonably request to qualify or register the Shares for offering and sale under (or obtain exemptions from the application of) the securities laws of such jurisdictions as the Underwriters may request and comply with such laws so as to permit the continuance of sales and dealings therein in such jurisdictions for as long as may be necessary to complete the distribution of the Shares; provided that, notwithstanding the foregoing, the Company will not be required to (i) qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this paragraph or where it would be subject to taxation as a foreign corporation, or (ii) consent to general service of process in any such jurisdiction. The Company will advise ▇▇▇▇▇▇▇▇ Curhan Ford &Co. promptly of (i) the suspension of the qualification or registration of (or any such exemption relating to) the Shares for offering, sale or trading in any jurisdiction or any initiation of threat of any proceeding for any such purpose and (ii) any notification from NASDAQ regarding the delisting or suspension from trading of the Company’s securities, and in the event of the issuance of any order suspending such qualification, registration or exemption, the Company shall use its reasonable best efforts to obtain the withdrawal thereof at the earliest possible date.

(i) During the period commencing on the date hereof and ending 90 days after the date of the Prospectus (the “Lock-Up Period”), the Company shall not (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock, or (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Common Stock, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise, without the prior written consent of ▇▇▇▇▇▇▇▇ Curhan Ford & Co. (such consent not to be unreasonably withheld) and the prior consent of a majority of the Company’s independent directors.

The foregoing paragraph shall not apply to the issuance of securities pursuant to the Company’s equity compensation and employee stock purchase plans in the form and amount approved for issuance as described in the Registration Statement and the Prospectus or the exercise of options or warrants or the conversion of a security outstanding on the date of the Prospectus and which is described in the Registration Statement; provided, however, that the Company agrees that such issuances to any executive officers or directors of the Company and their respective affiliates shall be made subject to the terms of the form of Lock-Up Agreement

attached hereto as Exhibit A. The Company also agrees that during such period, the Company will not file any registration statement, preliminary prospectus or prospectus, or any amendment or supplement thereto, under the Act for any such transaction or which registers, or offers for sale, Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock, except for a registration statement on Form S-8 relating to employee benefit plans or a post-effective amendment to any existing registration statement registering the resale or sale of Company securities. The Company agrees that if (a) during the last 17 days of the Lock-Up Period, the Company issues an earnings release or material news or a material event relating to the Company occurs, or (b) prior to the expiration of the Lock-Up Period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the Lock-Up Period, the restrictions set forth herein 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, as applicable, unless ▇▇▇▇▇▇▇▇ Curhan Ford & Co. waives, in writing, such extension.

(j) As soon as practicable, but in any event not later than forty five (45) days after the end of the 12-month period beginning on the day after the end of the fiscal quarter of the Company during which the effective date of the Registration Statement is deemed to occur pursuant to Rule 158(c), the Company will make generally available to its security holders (within the meaning of Section 11(a) of the Act) an earnings statement of the Company meeting the requirements of Rule 158(a) under the Act covering a period of at least twelve (12) months beginning after the Effective Date, and advise the Underwriters that such statement has been so made available.

(k) The Company will apply the net proceeds (“Proceeds”) it realizes from the sale of the Shares in the manner set forth under the caption “Use of Proceeds” in the Pricing Prospectus.

(l) During the course of the distribution of the Shares, the Company will not and the Company will cause its officers and directors not to take, directly or indirectly, any action designed to or which might, in the future, cause or result in stabilization or manipulation of the price of the Shares.

(m) The Company will use its best efforts, at its cost and expense, to take all necessary and appropriate action to list the Shares on The NASDAQ Capital Market and maintain such listing for as long as the Shares are so qualified.

(n) The Company will, upon request of any Underwriter, furnish, or cause to be furnished, to such Underwriter an electronic version of the Company’s trademarks, servicemarks and corporate logo for use on the website, if any, operated by such Underwriter for the purpose of facilitating the on-line offering of the Shares (the “License”); provided, however, that the License shall be used solely for the purpose described above, shall be granted without any fee and shall not be assigned or transferred.

(o) On the Closing Date, all transfer or other taxes (other than income taxes) which are required to be paid in connection with the sale and transfer of the Shares will have been fully paid by the Company and all laws imposing such taxes, if any, will have been fully complied with.

(p) Subsequent to the dates as of which information is given in the Registration Statement and Pricing Prospectus and prior to the Closing Date, except as disclosed in or contemplated by the Registration Statement and Pricing Prospectus, (i) the Company will not have incurred any liabilities or obligations, direct or contingent, or entered into any material transactions other than in the ordinary course of business; (ii) there shall not have been any change in the capital stock, funded debt (other than regular repayments of principal and interest on existing indebtedness) or other securities of the Company (except as contemplated in the Registration Statement), or any Material Adverse Effect; and (iii) the Company shall not have paid or declared any dividend or other distribution on its Common Stock or its other securities or redeemed or repurchased any of its Common Stock or other securities.

(q) The Company agrees that it has not made and, without the prior written consent of ▇▇▇▇▇▇▇▇ Curhan Ford & Co., it will not make any offer relating to the Shares that would constitute a “free writing prospectus” as defined in Rule 433 under the Act.

(r) The Company has complied with and will comply with the requirements of Rule 433 under the Act applicable to any Issuer Free Writing Prospectus, including timely filing with the Commission or retention where required and legending.

(s) The Company 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 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 Company will give prompt notice thereof to ▇▇▇▇▇▇▇▇ Curhan Ford & Co., will prepare and furnish without charge to each Underwriter an Issuer Free Writing Prospectus that will correct such statement or omission.

(t) Prior to the latest of the First Closing Date and the Option Closing Date, the Company will not issue any press release or other communication directly or indirectly or hold any press conference with respect to the Company, its condition, financial or otherwise, or earnings, business affairs or business prospects (except for routine oral communications in the ordinary course of business and consistent with past practices of the Company and of which ▇▇▇▇▇▇▇▇ Curhan Ford & Co. are notified in advance), without the prior written consent of ▇▇▇▇▇▇▇▇ Curhan Ford & Co., unless in the judgment of the Company and its counsel, and after notification of ▇▇▇▇▇▇▇▇ Curhan Ford & Co., such press release or communication is required by law.

▇▇▇▇▇▇▇▇ Curhan Ford & Co., on behalf of the several Underwriters, may, in its sole discretion, waive in writing the performance by the Company of any one or more of the foregoing covenants or extend the time for their performance. Notwithstanding the foregoing, ▇▇▇▇▇▇▇▇ Curhan Ford & Co., for the benefit of each of the other Underwriters, agrees not to consent to any action proposed to be taken by the Company or any other holder of the Company’s securities that would otherwise be prohibited by, or to waive compliance by the

Company or any such other security holder with the provisions of, any Lock-Up Agreement delivered in accordance with Section 4(i) hereof without giving each of the other Underwriters at least 16 days prior notice (or such shorter notice as each of the other Underwriters may deem acceptable to permit compliance with applicable provisions of NASD Conduct Rule 2711(f) restricting publication and distribution of research and public appearance by research analysts before and after the expiration, waiver or termination of a lock-up agreement).

5. Indemnity and Contribution by the Company and the Underwriters.

(a) The Company shall indemnify, defend and hold harmless each Underwriter and any person who controls any Underwriter within the meaning of Section 15 of the Act or Section 20 of the 1934 Act, from and against any loss, expense, liability, damage or claim (including the reasonable cost of investigation) which the Underwriters or any such controlling person may incur insofar as such loss, expense, liability, damage or claim arises out of or, is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or in the Registration Statement as amended by any post-effective amendment thereof by the Company) or the Prospectus (the term Prospectus for the purpose of this Section 5 being deemed to include any Preliminary Prospectus, Pricing Prospectus, Issuer Free Writing Prospectus, the Prospectus and any Prospectus supplements, in each case as amended or supplemented by the Company), (ii) any application or other document, or any amendment or supplement thereto, executed by the Company or based upon written information furnished by or on behalf of the Company filed in any jurisdiction (domestic or foreign) 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 (iii) any omission or alleged omission to state a material fact required to be stated in any such Registration Statement, Prospectus or Application or necessary to make the statements made therein in light of the circumstances under which they were made, not misleading; except, in the case of each of clauses (i), (ii) or (iii), to the extent that any such loss, expense, liability, damage or claim arises out of or is based upon (x) any such untrue statement or omission of a material fact contained in and in conformity with information furnished in writing by or on behalf of the Underwriters to the Company expressly for use in such Registration Statement or such Prospectus or (y) sales to any person asserting any such loss, expense, liability, damage or claim incurred from purchasing the Shares, if a copy of the Pricing Disclosure Package or the Prospectus (in each case, as then amended or supplemented if the Company shall have timely furnished any amendments or supplements thereto) was not sent or given by or on behalf of such Underwriter to such person, if required by law to have been delivered, at or prior to the written confirmation of the sale of the Shares to such person, and if the Pricing Disclosure Package or the Prospectus (in each case, as so amended or supplemented), as applicable, would have cured the defect giving rise to such loss, expense, liability, damage or claim, unless such failure is the result of noncompliance by the Company.

(b) Each of the Underwriters shall, severally and not jointly, indemnify, defend and hold harmless the Company and its directors, officers, employees and agents, each person who controls the Company, as the case may be, within the meaning of Section 15 of the Act or Section 20 of the 1934 Act from and against any loss, expense, liability, damage or claim (including the reasonable cost of investigation) which, jointly or severally, the Company, or any

such person may incur but only insofar as such loss, expense, liability, damage or claim arises out of or is based upon (i) any untrue statement of a material fact contained in the Registration Statement (or in the Registration Statement as amended by any post-effective amendment thereof by the Company) or the Prospectus in reliance upon and in conformity with information furnished in writing by or on behalf of such Underwriter to the Company expressly for inclusion in the Registration Statement (or in the Registration Statement as amended by any post-effective amendment thereof by the Company) or the Prospectus, as specified in the last sentence of this Section 5(b), or (ii) any omission to state a material fact regarding such Underwriter required to be stated in such Registration Statement or the Prospectus or necessary to make such statement not misleading. The obligation of each of the Underwriters to indemnify the Company (including any director, officer, employee, agent or control person thereof) shall only relate to any untrue statement or omission which applies to the Underwriter. The Company and the Underwriters acknowledge that the information set forth (x) on the cover page of the Prospectus concerning the Underwriters, relating to the delivery of the Shares, and (y) under the caption “Underwriting” in the Prospectus with respect to passive market and stabilization activities by the Underwriters, constitute the only information furnished by or on behalf of the Underwriters to the Company for purposes of this Section 5.

(c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of any claims or 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 in writing each party against whom indemnification is to be sought of the claim or the commencement thereof (but the failure so to notify an indemnifying party shall not (i) relieve the indemnifying party from any liability which it may have under this Section 5, to the extent that it did not otherwise learn of such action and such failure does not materially prejudice the indemnifying party as a result thereof, and (ii) in any event shall not relieve it from any liability that such indemnifying party may have otherwise than on account of the indemnity agreement hereunder). The indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be reasonably satisfactory to the indemnified party. The indemnifying party may participate in the defense of such action at its own expense, and to the extent it may elect, by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, the indemnifying party may assume the defense thereof with counsel reasonably satisfactory to such indemnified party; provided, however, that counsel to the indemnifying party shall not (except with the written consent of the indemnified party) also be counsel to the indemnified party. Notwithstanding the foregoing, the indemnified party or parties shall have the right to employ its or their own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of such indemnified party or parties unless (i) the employment of such counsel shall have been authorized in writing by one of the indemnifying parties in connection with the defense of such action, (ii) the indemnifying parties shall not have employed reasonably satisfactory counsel to have charge of the defense of such action within a reasonable time after notice of commencement of the action, (iii) the indemnifying party does not diligently defend the action after assumption of the defense, or (iv) such indemnified party or parties shall have reasonably concluded based on the advice of the

advice of counsel that there may be defenses available to it or them which are different from or additional to those available to one or all of the indemnifying parties (in which case the indemnifying parties shall not have the right to direct the defense of such action on behalf of the indemnified party or parties), in any of which events the fees and expenses of one counsel selected by all of the indemnified parties to represent them all (in addition to one local counsel selected by all of the indemnified parties to represent them all in each applicable jurisdiction) shall be borne by the indemnifying parties. In the case of any separate counsel for the Company and its officers, directors and control persons, such counsel shall be designated in writing by the Company. In the case of any separate counsel for the Underwriters and their respective officers, directors and control persons, such counsel shall be designated in writing by ▇▇▇▇▇▇▇▇ Curhan Ford & Co. No indemnifying party shall, without the prior written consent of the indemnified parties, effect any settlement or compromise of, or consent to the entry of judgment with respect to, any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could have been sought under this Section 5 (whether or not the indemnified parties are actual or potential parties thereto), unless (x) such settlement, compromise or consent (I) includes an unconditional release of the indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (II) does not include a statement as to, or an admission of, fault, culpability or a failure to act, by or on behalf of the indemnified party, and (y) the indemnifying party reaffirms its indemnification obligations pursuant to this Agreement.

(d) If the indemnification provided for in this Section 5 is unavailable to an indemnified party under subsections (a) or (b) of this Section 5 in respect of any losses, expenses, liabilities, damages or claims referred to therein, then each applicable indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, expenses, liabilities, damages or claims (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other hand from the offering of the Shares or (ii) if (but only if) the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and the Underwriters on the other with respect to the statements or omissions which resulted in such losses, expenses, liabilities, damages or claims, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other with respect to such offering shall be deemed to be in the same proportion as the total proceeds (net of underwriting discounts and commissions but before deducting expenses) received by the Company from the Shares sold under this Agreement, on the one hand, and the total underwriting discounts and commissions received by the Underwriters with respect to the Shares purchased under this Agreement, on the other hand, bear to the total gross proceeds from the offering of the Shares under this Agreement, in each case as set forth in the table on the cover page of the Prospectus. The relative fault of the Company on the one hand and the Underwriters on the other shall be determined by reference to, among other things, (x) whether the untrue statement or alleged untrue statement of a material fact or omission or alleged omission relates to information supplied by the Company or by the Underwriters, (y) the intent of the parties, and (z) their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by a party as a result of the losses, claims, damages and liabilities referred to above shall be deemed to include any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any claim or action.

(e) The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to Section 5(d) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in Section 5(d)(i) and, if applicable, Section 5(d)(ii), above. Notwithstanding the provisions of this Section 5, (i) none of the Underwriters shall be required to contribute any amount in excess of the underwriting discounts and commissions applicable to the Shares purchased by the Underwriters and, (ii) no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in Section 5(d) shall be several in proportion to their respective underwriting obligations and not joint.

The indemnity and contribution contained in this Section 5 shall remain operative and in full force and effect regardless of (i) any termination of this Agreement and (ii) any investigation made by or on behalf of the Underwriters or the Company and the Subsidiaries and such party’s officers or directors or any person controlling such parties.

6. Survival of Agreements, etc. All statements contained in any certificate delivered by or on behalf of the parties in connection with this Agreement shall be deemed to be representations and warranties hereunder. Notwithstanding any investigations made by or on behalf of the parties to this Agreement, all representations, warranties, indemnities and agreements made by the parties to this Agreement or pursuant hereto shall remain in full force and effect and will survive delivery of and payment for the Shares. The provisions of Sections 4, 5, 11 and 15 shall survive the termination or cancellation of this Agreement.

7. Conditions of Underwriters’ Obligations. The respective obligations of the Underwriters to purchase and pay for the Firm Shares as provided herein on the First Closing Date and, with respect to the Option Shares, the Option Closing Date, shall be subject to the accuracy of the representations and warranties on the part of the Company set forth in Section 1 hereof as of the date hereof and as of the First Closing Date as though then made and, with respect to the Option Shares, as of the Option Closing Date as though then made, to the timely performance by the Company of their respective covenants and obligations hereunder, and to each of the following additional conditions:

(a) The Registration Statement shall have become effective prior to the execution of this Agreement, or at such later date as shall be consented to in writing by the Underwriters; no stop order suspending the effectiveness thereof shall have been issued and no proceedings for that purpose shall have been initiated or, to the Knowledge of the Company or any Underwriter, threatened by the Commission; any request of the Commission for additional information (to be included in the Registration Statement, any Preliminary Prospectus, any Pricing Prospectus, the Prospectus or otherwise) shall have been complied with to the satisfaction of Underwriters’ Counsel; FINRA shall have raised no objection to the fairness and reasonableness of the underwriting terms and arrangements; and no amendment to the Registration Statement, any Preliminary Prospectus, any Pricing Prospectus, or the Prospectus to

which the Underwriters or Underwriters’ Counsel shall have reasonably objected, after having received reasonable notice of a proposal to file the same, shall have been filed; and NASDAQ shall not have required a vote of stockholders of the Company in connection with the consummation of the transactions contemplated by this Agreement.

(b) All corporate proceedings and other legal matters in connection with this Agreement, the form of Registration Statement, any Preliminary Prospectus, any Pricing Prospectus, and the Prospectus and the registration, authorization, issue, sale and delivery of the Shares, shall have been reasonably satisfactory to Underwriters’ Counsel, and such counsel shall have been furnished with such papers and information as they may reasonably have requested to enable them to pass upon the matters referred to in this Section 7.

(c) Subsequent to the execution and delivery of this Agreement and prior to the First Closing Date, and on the Option Closing Date, as the case may be, there shall not have occurred any change, or any development involving a prospective change, in the condition, financial or otherwise, or in the earnings, business or operations of the Company, taken as a whole, from that set forth in the Pricing Disclosure Package that, in the sole judgment of ▇▇▇▇▇▇▇▇ Curhan Ford & Co., is material and adverse and that makes it, in the sole judgment of ▇▇▇▇▇▇▇▇ Curhan Ford & Co., impracticable or inadvisable to market the Shares on the terms and in the manner contemplated in the Pricing Disclosure Package.

(d) At the First Closing Date and on the Option Closing Date, as the case may be, the Underwriters shall have received from ▇▇▇▇▇▇▇ Procter LLP, counsel for the Company (“Company Counsel”), a signed opinion dated as of such Closing Date, reasonably satisfactory to Underwriters’ Counsel, in the form and substance of Exhibit B annexed hereto, including a signed negative assurance statement dated as of such Closing Date, reasonably satisfactory to Underwriters’ Counsel, in the form and substance reflected in Exhibit B.

LLP, independent public accountants, containing statements and information of the type ordinarily included in accountants’ “comfort letters” with respect to the financial statements and certain financial information contained in the Registration Statement, any Preliminary Prospectus, any Pricing Prospectus, and the Prospectus; provided, however, that the letter delivered on the Closing Date shall use a “cut-off date” not earlier than two business days before the Closing Date.

(g) The Underwriters shall have received, on each of the date hereof and the Closing Date, a letter dated the date hereof or the Closing Date, as the case may be, in form and substance satisfactory to the Underwriters, from Ernst & Young LLP, independent public accountants, containing statements and information of the type ordinarily included in accountants’ “comfort letters” with respect to the financial statements and certain financial

(i) The representations and warranties of the Company in this Agreement are true and correct, as if made on and as of the First Closing Date or the Option Closing Date, as the case may be, and the Company has complied with all the agreements and satisfied all the conditions on its part to be performed or satisfied at or prior to the First Closing Date or the Option Closing Date, as the case may be;

(ii) When the Registration Statement became effective and at all times subsequent thereto up to the delivery of such certificate, the Registration Statement, the Pricing Prospectus and the Prospectus, and any amendments or supplements thereto, contained all material information required to be included therein by the Act and the applicable rules and regulations of the Commission thereunder, as the case may be, and in all material respects conformed to the requirements of the Act and the applicable Rules and Regulations thereunder, the Registration Statement, any Preliminary Prospectus, any Pricing Prospectus, and the Prospectus, and any amendments or supplements thereto, did not and does not include any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; and, since the effective date of the Registration Statement, there has occurred no event required to be set forth in an amended or supplemented Prospectus or Issuer Free Writing Prospectus which has not been so set forth; and

(iii) Subsequent to the respective dates as of which information is given in the Registration Statement, any Preliminary Prospectus, any Pricing Prospectus, and the Prospectus, there has not been or occurred, as the case may be: (A) any Material Adverse Effect; (B) any transaction that is material to the Company and its Subsidiaries considered as a whole, except transactions entered into in the ordinary course of business; (C) any obligation, direct or contingent, that is material to the Company and its Subsidiaries considered as a whole, incurred by the Company or its subsidiaries, except obligations incurred in the ordinary course of business; (D) any change in the capital stock or outstanding indebtedness of the Company or any of its Subsidiaries that is material to the Company and its Subsidiaries considered as a whole; (E) any dividend or distribution of any kind declared, paid or made on the capital stock of the Company or any of its Subsidiaries; or (F) any loss or damage (whether or not insured) to the property of the Company or any of its Subsidiaries which has been sustained or will have been sustained which has a Material Adverse Effect.

If any condition specified in this Section 7 is not satisfied when and as required to be satisfied, this Agreement may be terminated by the Underwriters by written notice to the Company at any time on or prior to the First Closing Date and, with respect to the Option Shares, at any time prior to the Option Closing Date, which termination shall be without liability on the part of any party to any other party, except for the expenses described in Section 11 of this Agreement.

8. Default of One or More of the Underwriters. Subject to Sections 7 and 10 hereof, if, on the First Closing Date or the Option Closing Date, as the case may be, any one or more of the Underwriters shall fail or refuse to purchase Shares that it or they have agreed to purchase hereunder on such date, and the aggregate number of Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase does not exceed 10% of the aggregate number of the Shares to be purchased on such date, the other Underwriters shall be obligated, severally, in the proportions that the number of Firm Shares set forth opposite their respective names on Schedule A bears to the aggregate number of Firm Shares set forth opposite the names of all such non-defaulting Underwriters, to purchase the Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date. If, on the First Closing Date or the Option Closing Date, as the case may be, any one or more of the Underwriters shall fail or refuse to purchase Shares and the aggregate number of Shares with respect to which such default occurs exceeds 10% of the aggregate number of Shares to be purchased on such date, and arrangements satisfactory to the Company and the other Underwriters for the purchase of such Shares are not made within 48 hours after such default, this Agreement shall terminate without liability of any non-defaulting Underwriter or the Company, except that the provisions of Sections 5, 11 and 15 shall at all times be effective and shall survive such termination. In any such case either the Underwriters or the Company shall have the right to postpone the First Closing Date or the Option Closing Date, as the case may be, but in no event for longer than seven (7) days in order that the required changes, if any, to the Registration Statement and the Prospectus or any other documents or arrangements may be effected.
