Ladies and Gentlemen:

Golf Galaxy, Inc., a Minnesota corporation (the “Company”), and the shareholders of the Company listed in Schedule I hereto (the “Selling Shareholders”) severally propose to sell to the several Underwriters named in Schedule II hereto (the “Underwriters”) an aggregate of                    shares (the “Firm Shares”) of Common Stock, $0.01 par value per share (the “Common Stock”), of the Company. The Firm Shares consist of                    authorized but unissued shares of Common Stock to be issued and sold by the Company,                    outstanding shares of Common Stock to be sold by certain of the Selling Shareholders and                    authorized but unissued shares of Common Stock to be issued upon the exercise of currently exercisable stock options to be sold by certain of the Selling Shareholders. Certain of the Selling Shareholders have also granted to the several Underwriters an option to purchase up to                    additional shares of Common Stock, on the terms and for the purposes set forth in Section 3 hereof (the “Option Shares”). The Firm Shares and any Option Shares purchased pursuant to this Agreement are herein collectively called the “Securities.”

The Company and the Selling Shareholders hereby confirm their agreement with respect to the sale of the Securities to the several Underwriters, for whom you are acting as representatives (the “Representatives”).

(1)                                  Plus an option to purchase up to              additional shares to cover over allotments.

1.                                       Registration Statement and Prospectus. A registration statement on Form S-1 (File No. 333-                ) with respect to the Securities, including a preliminary form of prospectus, 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 (“Rules and Regulations”) of the Securities and Exchange Commission (the “Commission”) thereunder and has been filed with the Commission; one or more amendments to such registration statement have also been so prepared and have been, or will be, so filed; and, if the Company has elected to rely upon Rule 462(b) of the Rules and Regulations to increase the size of the offering registered under the Act, the Company will prepare and file with the Commission a registration statement with respect to such increase pursuant to Rule 462(b). Copies of such registration statement(s) and amendments and each related preliminary prospectus have been delivered to you.

If the Company has elected not to rely upon Rule 430A of the Rules and Regulations, the Company has prepared and will promptly file an amendment to the registration statement and an amended prospectus. If the Company has elected to rely upon Rule 430A of the Rules and Regulations, it will prepare and file a prospectus pursuant to Rule 424(b) that discloses the information previously omitted from the prospectus in reliance upon Rule 430A. Each part of such registration statement as amended at the time it is or was declared effective by the Commission, and, in the event of any amendment thereto after the effective date, each part of such registration statement as so amended (but only from and after the effectiveness of such amendment), including a registration statement (if any) filed pursuant to Rule 462(b) of the Rules and Regulations increasing the size of the offering registered under the Act and information (if any) deemed to be part of the registration statement at the time of effectiveness pursuant to Rule 430A(b) of the Rules and Regulations, is hereinafter called the “Registration Statement.”  The prospectus included in the Registration Statement at the time it is or was declared effective by the Commission is hereinafter called the “Prospectus,” except that if any prospectus filed by the Company with the Commission pursuant to Rule 424(b) of the Rules and Regulations or any other such prospectus provided to the Underwriters by the Company for use in connection with the offering of the Securities (whether or not required to be filed by the Company with the Commission pursuant to Rule 424(b) of the Rules and Regulations), but not including a “free writing prospectus” as defined in Rule 405 of the Rules and Regulations) differs from the prospectus on file at the time the Registration Statement is or was declared effective by the Commission, the term “Prospectus” shall refer to such differing prospectus from and after the time such prospectus is filed with the Commission or transmitted to the Commission for filing pursuant to such Rule 424(b) or from and after the time of its first use within the meaning of the Rules and Regulations. The term “Preliminary Prospectus” as used herein means any preliminary prospectus included in the Registration Statement prior to the time the Registration Statement becomes or became effective under the Act and any prospectus subject to completion as described in Rule 430A of the Rules and Regulations. All references in this Agreement to the Registration Statement, any Preliminary Prospectus, the Prospectus or any amendment or supplement to any of the foregoing, shall be deemed to include the copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval System (“▇▇▇▇▇”).

(a)                                  The Company represents and warrants to, and agrees with, the several Underwriters as follows:

(i)                                     No order preventing or suspending the use of any Preliminary Prospectus has been issued by the Commission and each Preliminary Prospectus, at the time of filing thereof, or the time of first use within the meaning of the Rules and Regulations, complied in all material respects with the requirements of the Securities Act and the Rules and Regulations and did not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; except that the foregoing shall not apply to statements in or omissions from any Preliminary Prospectus in reliance upon, and in conformity with, written information furnished to the Company by you, or by any Underwriter through you, specifically for use in the preparation thereof.

(ii)                                  As of the time any part of the Registration Statement (or any post-effective amendment thereto, including a registration statement (if any) filed pursuant to Rule 462(b) of the Rules and Regulations increasing the size of the offering registered under the Act) became effective upon the filing or first use within the meaning of the Rules and Regulations of the Prospectus (or any supplement to the Prospectus) and at the First Closing Date and Second Closing Date (as hereinafter defined), (A) the Registration Statement and the Prospectus (in each case, as so amended and/or supplemented) conformed or will conform in all material respects to the requirements of the Act and the Rules and Regulations, (B) the Registration Statement (as so amended) did not or will not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading, and (C) the Prospectus (as so supplemented) did not or will not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they are or were made, not misleading; except that the foregoing shall not apply to statements in or omissions from any such document in reliance upon, and in conformity with, written information furnished to the Company by you, or by any Underwriter through you, specifically for use in the preparation thereof. If the Registration Statement has been declared effective by the Commission, no stop order suspending the effectiveness of the Registration Statement has been issued, and no proceeding for that purpose has been initiated or, to the Company’s knowledge, threatened by the Commission.

(iii)                               Neither (A) the Issuer General Free Writing Prospectus(es) issued at or prior to the Time of Sale and the Statutory Prospectus, all considered together (collectively, the “Time of Sale Disclosure Package”), nor (B) any individual Issuer Limited-Use Free Writing Prospectus, when considered together with the Time of Sale Disclosure Package, includes or included as of the Time of Sale any untrue statement of a material fact or omit or omitted as of the Time of Sale to state any material fact necessary

in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The preceding sentence does not apply to statements in or omissions from any Statutory Prospectus included in the Registration Statement or any Issuer Free Writing Prospectus based upon and in conformity with written information furnished to the Company by you or by any Underwriter through you specifically for use therein. As used in this paragraph and elsewhere in this Agreement:

(2)                                  “Statutory Prospectus” as of any time means the prospectus that is included in the Registration Statement immediately prior to that time. For purposes of this definition, information contained in a form of prospectus that is deemed retroactively to be a part of the Registration Statement pursuant to Rule 430A shall be considered to be included in the Statutory Prospectus as of the actual time that form of prospectus is filed with the Commission pursuant to Rule 424(b) under the Act.

(3)                                  “Issuer Free Writing Prospectus” means any “issuer free writing prospectus,” as defined in Rule 433 under the Act, relating to the Securities that (A) is required to be filed with the Commission by the Company, or (B) is exempt from filing pursuant to Rule 433(d)(5)(i) under the Act because it contains a description of the Securities or of the offering that does not reflect the final terms or pursuant to Rule 433(d)(8)(i) because it is an electronic road show which is made available, in each case in the form filed or required to be filed with the Commission or, if not required to be filed, in the form retained in the Company’s records pursuant to Rule 433(g) under the Act.

(4)                                  “Issuer General Free Writing Prospectus” means any Issuer Free Writing Prospectus that is intended for general distribution to prospective investors, as evidenced by its being specified in Schedule III to this Agreement.

The term Issuer Limited-Use Free Writing Prospectus also includes any electronic road show that is made available even though not required to be filed with the Commission.

(iv)                              (A) Each Issuer Free Writing Prospectus, as of its issue date and at all subsequent times through the completion of the public offer and sale of the Securities or until any earlier date that the Company notified or notifies the Representatives as described in Section 4(a)(iii)(B), did not, does not and will not include any information that conflicted, conflicts or will conflict with the information contained in the Registration Statement, any Statutory Prospectus or the Prospectus. The foregoing sentence does not apply to statements in or omissions from any Issuer Free Writing Prospectus based upon and in conformity with

4

written information furnished to the Company by you or by any Underwriter through you specifically for use therein.

(B)                                (1) At the time of filing the Registration Statement and (2) at the date hereof, the Company was not and is not an “ineligible issuer,” as defined in Rule 405 under the Act, including the Company or any subsidiary in the preceding three years not having been convicted of a felony or misdemeanor or having been made the subject of a judicial or administrative decree or order as described in Rule 405 (without taking account of any determination by the Commission pursuant to Rule 405 that it is not necessary that the Company be considered an ineligible issuer), nor an “excluded issuer” as defined in Rule 164 under the Act.

(C)                                Each Issuer Free Writing Prospectus satisfied, as of its issue date and at all subsequent times through the completion of the public offer and sale of the Securities, all other conditions to use thereof as set forth in Rules 164 and 433 under the Act.

No other financial statements or schedules are required to be included in the Registration Statement, the Time of Sale Disclosure Package or the Prospectus.

The execution, delivery and performance of this Agreement and the consummation of the transactions herein contemplated will not result in a breach or violation of any of the terms and provisions of, or constitute a default under, any statute, any material agreement or instrument to which

The execution and delivery of this Agreement, the Custody Agreement and the Power of Attorney and the performance of the terms hereof and thereof and the consummation of the transactions herein and therein contemplated will not result in a breach or violation of any of the terms and provisions of, or constitute a default under, any material agreement or instrument to which such Selling Shareholder is a party or by which such Selling Shareholder is bound, or any law, regulation, order or decree applicable to such Selling Shareholder; no consent, approval, authorization or order of, or filing with, any court or governmental agency or body is required for the execution, delivery and performance of this Agreement, the Custody Agreement and the Power of Attorney or for the consummation of the transactions contemplated hereby and thereby, including the sale of the Securities being sold by such Selling Shareholder, except such as may be required under the Act or state securities laws or blue sky laws.

(vi)                              Such Selling Shareholder has not distributed and will not distribute any prospectus or other offering material in connection with the offering and sale of the Securities other than any Preliminary Prospectus or the Prospectus or other materials permitted by the Act to be distributed by such Selling Shareholder; provided, however, that no Selling Shareholder has made nor will make any offer relating to the Securities that would constitute a “free writing prospectus” as defined in Rule 405 under the Act except a Permitted Free Writing Prospectus authorized by the Company and the Underwriters for distribution in accordance with the provisions of Section 4(a)(xix) hereof.

3.                                       Purchase, Sale and Delivery of Securities.

(a)                                  On the basis of the representations, warranties and agreements herein contained, but subject to the terms and conditions herein set forth, the Company agrees to issue and sell                    Firm Shares, and each Selling Shareholder agrees, severally and not jointly, to sell the number of Firm Shares set forth opposite the name of such Selling Shareholder in Schedule I hereto, to the several Underwriters, and each Underwriter agrees, severally and not jointly, to purchase from the Company and the Selling Shareholders the number of Firm Shares set forth opposite the name of such Underwriter in Schedule II hereto. The purchase price for each Firm Share shall be $     per share. The obligation of each Underwriter to each of the Company and the Selling Shareholders shall be to purchase from each of the Company and the Selling Shareholders that number of Firm Shares (to be adjusted by the Representatives to avoid fractional shares) which represents the same proportion of the number of Firm Shares to be sold by each of the Company and the Selling Shareholders pursuant to this Agreement as the number of Firm Shares set forth opposite the name of such Underwriter in Schedule II hereto represents to the total number of Firm Shares to be purchased by all Underwriters pursuant to this Agreement. In making this Agreement, each Underwriter is contracting severally and not jointly; except as provided in paragraph (c) of this Section 3 and in Section 8 hereof, the agreement of each Underwriter is to purchase only the respective number of Firm Shares specified in Schedule II.

The Firm Shares will be delivered by the Company and the Custodian to you for the accounts of the several Underwriters against payment of the purchase price therefor by wire transfer of same day funds payable to the order of the Company and the Custodian, as appropriate, at the offices of ▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co., ▇▇▇ ▇▇▇▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇, or such other location as may be mutually acceptable, at 9:00 a.m. Central time on the third (or if the Securities are priced, as contemplated by Rule 15c6-1(c) under the Exchange Act, after 4:30 p.m. Eastern time, the fourth) full business day following the date hereof, or at such other time and date as you and the Company determine pursuant to Rule 15c6-1(a) under the Exchange Act, such time and date of delivery being herein referred to as the “First Closing Date.”  If the Representatives so elect, delivery of the Firm Shares may be made by credit through full fast transfer to the accounts at The Depository Trust Company designated by the Representatives. Certificates representing the Firm Shares, in definitive form and in such denominations and registered in such names as you may request upon at least two business days’ prior notice to the Company and the Custodian, will be made available for checking and packaging not later than 10:30 a.m., Central time, on the business day next preceding the First Closing Date at the offices of ▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co., Minneapolis, Minnesota, or such other location as may be mutually acceptable.

(b)                                 On the basis of the representations, warranties and agreements herein contained, but subject to the terms and conditions herein set forth, certain of the Selling Shareholders, with respect to the number of Option Shares set forth opposite the name of such Selling Shareholder in Schedule I hereto, hereby grant to the several Underwriters an option to purchase all or any portion of the Option Shares at the same purchase price as the Firm Shares, for use solely in covering any over-allotments made by the Underwriters in the sale and distribution of the Firm Shares. The option granted hereunder may be exercised in whole or in

13

part at any time (but not more than once) within 30 days after the effective date of this Agreement upon notice (confirmed in writing) by the Representatives to the Attorneys-in-Fact setting forth the aggregate number of Option Shares as to which the several Underwriters are exercising the option, the names and denominations in which the certificates for the Option Shares are to be registered and the date and time, as determined by you, when the Option Shares are to be delivered, such time and date being herein referred to as the “Second Closing” and “Second Closing Date”, respectively; provided, however, that the Second Closing Date shall not be earlier than the First Closing Date nor earlier than the second business day after the date on which the option shall have been exercised. If the option is exercised, the obligation of each Underwriter shall be to purchase from the Selling Shareholders granting an option to purchase the Option Shares, that number of Option Shares (to be adjusted by the Representatives to avoid fractional shares) which represents the same proportion that the number of Option Shares granted by each such Selling Shareholder bears to the total number of Option Shares granted by all such Selling Shareholders. The number of Option Shares to be purchased by each Underwriter shall be the same percentage of the total number of Option Shares to be purchased by the several Underwriters as the number of Firm Shares to be purchased by such Underwriter is of the total number of Firm Shares to be purchased by the several Underwriters, as adjusted by the Representatives in such manner as the Representatives deem advisable to avoid fractional shares. No Option Shares shall be sold and delivered unless the Firm Shares previously have been, or simultaneously are, sold and delivered.

The Option Shares will be delivered by the Custodian to you for the accounts of the several Underwriters against payment of the purchase price therefor by wire transfer of same day funds payable to the order of the Custodian at the offices of ▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co., ▇▇▇ ▇▇▇▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇, or such other location as may be mutually acceptable at 9:00 a.m., Central time, on the Second Closing Date. If the Representatives so elect, delivery of the Option Shares may be made by credit through full fast transfer to the accounts at The Depository Trust Company designated by the Representatives. Certificates representing the Option Shares in definitive form and in such denominations and registered in such names as you have set forth in your notice of option exercise, will be made available for checking and packaging not later than 10:30 a.m., Central time, on the business day next preceding the Second Closing Date at the office of ▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co., ▇▇▇ ▇▇▇▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇, or such other location as may be mutually acceptable.

(c)                                  It is understood that you, individually and not as Representatives of the several Underwriters, may (but shall not be obligated to) make payment to the Company or the Selling Shareholders, on behalf of any Underwriter for the Securities to be purchased by such Underwriter. Any such payment by you shall not relieve any such Underwriter of any of its obligations hereunder. Nothing herein contained shall constitute any of the Underwriters an unincorporated association or partner with the Company or any Selling Shareholder.

4.                                       Covenants.

(a)                                  The Company covenants and agrees with the several Underwriters as follows:

(i)                                     If the Registration Statement has not already been declared effective by the Commission, the Company will use its best efforts to cause the Registration Statement and any post-effective amendments thereto to become effective as promptly as possible; the Company will notify you promptly of the time when the Registration Statement or any post-effective amendment to the Registration Statement has become effective or any supplement to the Prospectus has been filed and of any request by the Commission for any amendment or supplement to the Registration Statement or Prospectus or additional information; if the Company has elected to rely on Rule 430A of the Rules and Regulations, the Company will prepare and file a Prospectus containing the information omitted therefrom pursuant to Rule 430A of the Rules and Regulations with the Commission within the time period required by, and otherwise in accordance with the provisions of, Rules 424(b) and 430A, of the Rules and Regulations; if the Company has elected to rely upon Rule 462(b) of the Rules and Regulations to increase the size of the offering registered under the Act, the Company will prepare and file a registration statement with respect to such increase with the Commission within the time period required by, and otherwise in accordance with the provisions of, Rule 462(b); the Company will prepare and file with the Commission, promptly upon your reasonable request, any amendments or supplements to the Registration Statement or Prospectus that, in your opinion, may be necessary or advisable in connection with the distribution of the Securities by the Underwriters; and the Company will not file any amendment or supplement to the Registration Statement or Prospectus to which you shall reasonably object by notice to the Company after having been furnished a copy a reasonable time prior to the filing.

(ii)                                  The Company will advise you, promptly after it shall receive notice or obtain knowledge thereof, of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement, or any post-effective amendment thereto or preventing or suspending the use of any Preliminary Prospectus, the Time of Sale Disclosure Package, the Prospectus or any Issuer Free Writing Prospectus of the suspension of the qualification of the Securities for offering or sale in any jurisdiction, or of the initiation or threatening of any proceeding for any such purpose; and the Company will promptly use its reasonable efforts to prevent the issuance of any stop order or to obtain its withdrawal if such a stop order should be issued. Additionally, the Company agrees that it shall comply with the provisions of Rules 424(b) and 430A, as applicable, under the Act and will use its reasonable efforts to confirm that any filings made by the Company under Rule 424(b), Rule 433 or Rule 462 were received in a timely manner by the Commission.

(iii)                               (A)                              Within the time during which a prospectus (or in lieu thereof the notice referred to in Rule 173(a)) relating to the Securities is required to be delivered under the Act, the Company will comply as far as it is able with all

15

requirements imposed upon it by the Act, as now and hereafter amended, and by the Rules and Regulations, as from time to time in force, so far as necessary to permit the continuance of sales of or dealings in the Securities as contemplated by the provisions hereof, the Time of Sale Disclosure Package and the Prospectus. If during such period any event occurs as a result of which the Prospectus (or if the Prospectus is not yet available to prospective purchasers, the Time of Sale Disclosure Package) would include an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances then existing, not misleading, or if during such period it is necessary to amend the Registration Statement or supplement the Prospectus (or if the Prospectus is not yet available to prospective purchasers, the Time of Sale Disclosure Package) to comply with the Act, the Company will promptly notify you and will amend the Registration Statement or supplement the Prospectus (or if the Prospectus is not yet available to prospective purchasers, the Time of Sale Disclosure Package) (at the expense of the Company) so as to correct such statement or omission or effect such compliance.

(B)                                If at any time following issuance of an Issuer Free Writing Prospectus there occurred or occurs an event or development as a result of which such Issuer Free Writing Prospectus conflicted or would conflict with the information contained in the Registration Statement, any Statutory Prospectus or the Prospectus relating to the Securities or included or would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances prevailing at that subsequent time, not misleading, the Company has promptly notified or promptly will notify the Representatives and has promptly amended or will promptly amend or supplement, at its own expense, such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission.

(iv)                              The Company shall take or cause to be taken all necessary action to qualify the Securities for sale under the securities laws of such jurisdictions as you reasonably designate and to continue such qualifications in effect so long as required for the distribution of the Securities, except that the Company shall not be required in connection therewith to qualify as a foreign corporation or to execute a general consent to service of process in any state.

(v)                                 The Company will furnish to the Underwriters and counsel for the Underwriters copies of the Registration Statement (three of which will be signed and will include all consents and exhibits filed therewith), each Preliminary Prospectus, the Time of Sale Disclosure Package, the Prospectus, any Issuer Free Writing Prospectus and all amendments and supplements to such documents, in each case as soon as available and in such quantities as you may from time to time reasonably request.

(vi)                              During a period of five years commencing with the date hereof, the Company will furnish to the Representatives, and to each Underwriter who may so request in writing, copies of all periodic and special reports furnished to the shareholders of the Company and all information, documents and reports filed with the Commission, the NASD, Nasdaq or any securities exchange (other than any such information,

16

documents and reports that are filed with the Commission electronically via ▇▇▇▇▇ or any successor system).

(vii)                           The Company will make generally available to its security holders as soon as practicable, but in any event not later than 15 months after the end of the Company’s current fiscal quarter, an earnings statement (which need not be audited) covering a 12-month period beginning after the effective date of the Registration Statement that shall satisfy the provisions of Section 11(a) of the Act and Rule 158 of the Rules and Regulations.

(viii)                        The Company, whether or not the transactions contemplated hereunder are consummated or this Agreement is prevented from becoming effective under the provisions of Section 9(a) hereof or is terminated, will pay or cause to be paid  (A) all expenses (including transfer taxes allocated to the respective transferees) incurred in connection with the delivery to the Underwriters of the Securities, (B) all expenses and fees (including, without limitation, fees and expenses of the Company’s accountants and counsel but, except as otherwise provided below, not including fees of the Underwriters’ counsel) in connection with the preparation, printing, filing, delivery, and shipping of the Registration Statement (including the financial statements therein and all amendments, schedules, and exhibits thereto), the Securities, each Preliminary Prospectus, the Time of Sale Disclosure Package, the Prospectus, any Issuer Free Writing Prospectus and any amendment thereof or supplement thereto, and the printing, delivery, and shipping of this Agreement and other underwriting documents, including Blue Sky Memoranda (covering the states and other applicable jurisdictions), (C) all filing fees and fees and disbursements of the Underwriters’ counsel incurred in connection with the qualification of the Securities for offering and sale by the Underwriters or by dealers under the securities or blue sky laws of the states and other jurisdictions which you shall designate, (D) the fees and expenses of any transfer agent or registrar, (E) the filing fees and fees and disbursements of the Underwriters’ counsel incident to any required review by the NASD of the terms of the sale of the Securities, (F) listing fees, if any, and (G) all other costs and expenses incident to the performance of its obligations and the obligations of the Selling Shareholders hereunder that are not otherwise specifically provided for herein. If the sale of the Securities provided for herein is not consummated by reason of action by the Company pursuant to Section 9(a) hereof which prevents this Agreement from becoming effective, or by reason of any failure, refusal or inability on the part of the Company or the Selling Shareholders to perform any agreement on its or their part to be performed, or because any other condition of the Underwriters’ obligations hereunder required to be fulfilled by the Company or the Selling Shareholders is not fulfilled, the Company will reimburse the several Underwriters for all reasonable out-of-pocket disbursements (including reasonable fees and disbursements of counsel) incurred by the Underwriters in connection with their investigation, preparing to market and marketing the Securities or in contemplation of performing their obligations hereunder.

(x)                                   The Company will not, without the prior written consent of ▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co., from the date of execution of this Agreement and continuing to and including the date 90 days after the date of the Prospectus (the “Lock-Up Period”) offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, file with the Commission registration statement under the Act relating to, any shares of Securities or securities convertible into or exchangeable or exercisable for any shares of Securities, enter into a transaction which would have the same effect, or enter into any swap, hedge or other arrangement that transfers, in whole or in part, any of the economic consequences of ownership of the Securities, whether any such aforementioned transaction is to be settled by delivery of the Securities or such other securities, in cash or otherwise, or publicly disclose the intention to make any such offer, sale, pledge or disposition, or to enter into any such transaction, swap, hedge or other arrangement, without, in each case, the prior written consent of ▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co.; provided, however, that if (1) during the last 17 days of the Lock-Up Period, the Company releases earnings results or material news or a material event relating to the Company occurs or (2) 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, then in each case the Lock-Up Period will be extended until the expiration of the 18-day period beginning on the date of release of the earnings results or the occurrence of the material news or material event, as applicable, unless ▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. waives, in writing, such extension; provided, however, that the restrictions set forth in this subparagraph (x) shall not apply to (A) the sale of any Securities to the Underwriters pursuant to this Agreement; (B) sales in connection with the exercise of options granted and authorized to be granted under the Company’s 1996 Stock Option and Incentive Plan, as amended and restated, and 2004 Stock Incentive Plan (collectively, the “Stock Plans”); (C) the grant of options or stock awards to purchase up to an additional 100,000 shares under the Stock Plans; and (D) the sale of shares in connection with the exercise of those certain warrants each dated March 16, 2006, and issued to ▇▇▇▇ ▇. ▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇. ▇▇▇▇▇▇ and ▇▇▇▇▇ ▇. ▇▇▇▇▇▇, respectively. The Company agrees not to accelerate the vesting of any option or warrant or the lapse of any repurchase right prior to the expiration of the Lock-Up Period.

(xi)                                The Company either has caused to be delivered to you or will cause to be delivered to you prior to the effective date of the Registration Statement a Lock-Up Agreement in the form attached hereto as Annex A (the “Lock-Up Agreement”) from each of the Company’s directors, officers, Selling Shareholders and certain identified holders of more than five percent of the Company’s outstanding Common Stock. The Company will use commercially reasonable efforts to enforce the terms of each Lock-Up Agreement and issue stop-transfer instructions to the transfer agent for the

18

Common Stock with respect to any transaction or contemplated transaction that would constitute a breach of or default under the applicable Lock-Up Agreement.

(xii)                             The Company has not taken and will not take, directly or indirectly, any action designed to or which might reasonably be expected to cause or result in, or which has constituted, the stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Securities, and has not effected any sales of Common Stock which are required to be disclosed in response to Item 701 of Regulation S-K under the Act which have not been so disclosed in the Registration Statement.

(xviii)                   The Company and its subsidiaries will comply with all effective applicable provisions of the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act.

(xix)                           The Company represents and agrees that, unless it obtains the prior written consent of ▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co., and each Underwriter severally represents and agrees that, unless it obtains the prior written consent of the Company and ▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co., it has not made and will not make any offer relating to the Securities that would constitute an “issuer free writing prospectus,” as defined in Rule 433 under the Securities Act, or that would otherwise constitute a “free writing prospectus,” as defined in Rule 405 under the Securities Act, required to be filed with the Commission; provided that the

19

prior written consent of the parties hereto shall be deemed to have been given in respect of the free writing prospectuses included in Schedule III.

The Company represents that it has satisfied and agrees that it will satisfy the conditions in Rule 433 to avoid a requirement to file with the Commission any electronic road show.

(b)                                 Each Selling Shareholder, severally and not jointly, covenants and agrees with the several Underwriters with respect to itself as follows:

(i)                                     Except as otherwise agreed to by the Company and the Selling Shareholder pursuant to an outstanding registration rights agreement, a true and correct copy of which has been delivered to counsel to the Underwriters, such Selling Shareholder will pay all taxes, if any, on the transfer and sale, respectively, of the Securities being sold by such Selling Shareholder, and the fees of such Selling Shareholder’s separate counsel.

(ii)                                  The Securities to be sold by such Selling Shareholder, represented by the certificates and option agreements, as applicable, on deposit with the Custodian pursuant to the Custody Agreement of such Selling Shareholder, are subject to the interest of the several Underwriters and the other Selling Shareholders; the arrangements made for such custody are, except as specifically provided in the Custody Agreement, irrevocable; and the obligations of such Selling Shareholder hereunder shall not be terminated, except as provided in this Agreement or in the Custody Agreement, by any act of such Selling Shareholder, by operation of law, whether by the liquidation, dissolution or merger of such Selling Shareholder, by the death of such Selling Shareholder, or by the occurrence of any other event.

(iv)                              Such Selling Shareholder shall immediately notify you if any event occurs regarding such Selling Shareholder, or of any change in information relating to

20

such Selling Shareholder, which results in the Time of Sale Disclosure Package or in the Prospectus (as amended or supplemented) or any Issuer General Free Writing Prospectus including an untrue statement of a material fact regarding such Selling Shareholder or omitting to state any material fact necessary to make the statements therein regarding such Selling Shareholder, in light of the circumstances under which they were made, not misleading.

(v)                                 Such Selling Shareholder shall deliver to the Custodian or the Representatives, as appropriate, prior to the First Closing Date, a properly completed and executed United States Treasury Department Form W-9 (or other applicable form or statement specified by Treasury Department regulations in lieu thereof).

5.                                       Conditions of Underwriters’ Obligations.

6.                                       Indemnification and Contribution.

(a)                                  The Company agrees to indemnify and hold harmless each Underwriter against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the Act or otherwise (including in settlement of any litigation if such settlement is effected with the written consent of the Company), 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, including the information deemed to be a part of the Registration Statement at the time of effectiveness and at any subsequent time pursuant to Rules 430A and 430C of the Rules and Regulations, if applicable, any Preliminary Prospectus, the Time of Sale Disclosure Package, the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus or in any materials or information provided to investors by, or with the approval of, the Company in connection with the marketing of the offering of the Common Stock (“Marketing Materials”), including any road show or investor presentations made to investors by the Company (whether in

24

person or electronically) 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, and will reimburse each Underwriter for any legal or other expenses reasonably incurred by it in connection with investigating or defending against such loss, claim, damage, liability or action; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action 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 Time of Sale Disclosure Package, the Prospectus, or any such amendment or supplement, any Issuer Free Writing Prospectus or in any Marketing Materials, in reliance upon and in conformity with written information furnished to the Company by you, or by any Underwriter through you, specifically for use in the preparation thereof.

In addition to its other obligations under this Section 6(a), the Company agrees that, as an interim measure during the pendency of any claim, action, investigation, inquiry or other proceeding arising out of or based upon any statement or omission, or any alleged statement or omission, described in this Section 6(a), it will reimburse each Underwriter on a monthly basis for all reasonable legal fees or other expenses incurred in connection with investigating or defending any such claim, action, investigation, inquiry or other proceeding, notwithstanding the absence of a judicial determination as to the propriety and enforceability of the Company’s obligation to reimburse the Underwriters for such expenses and the possibility that such payments might later be held to have been improper by a court of competent jurisdiction. To the extent that any such interim reimbursement payment is so held to have been improper, the Underwriter that received such payment shall promptly return it to the party or parties that made such payment, together with interest, compounded daily, determined on the basis of the prime rate (or other commercial lending rate for borrowers of the highest credit standing) announced from time to time by U.S. Bank (the “Prime Rate”). Any such interim reimbursement payments which are not made to an Underwriter within 30 days of a request for reimbursement shall bear interest at the Prime Rate from the date of such request. This indemnity agreement shall be in addition to any liabilities which the Company may otherwise have.

(b)                                 Each Selling Shareholder, severally and not jointly, agrees to indemnify and hold harmless each Underwriter against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the Act or otherwise (including in settlement of any litigation if such settlement is effected with the written consent of such Selling Shareholder), 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, including the information deemed to be a part of the Registration Statement at the time of effectiveness pursuant to Rules 430A and 430C of the Rules and Regulations, if applicable, any Preliminary Prospectus, the Time of Sale Disclosure Package, the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus or any Marketing Materials, including any road show or investor presentations made to investors by the Company (whether in person or electronically) 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, and will reimburse each Underwriter for any legal or other expenses reasonably incurred by it in connection with investigating or

25

defending against such loss, claim, damage, liability or action; provided, however, that no Selling Shareholder shall be liable in any such case to the extent that any such loss, claim, damage, liability or action 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 Time of Sale Disclosure Package, the Prospectus, or any such amendment or supplement, any Issuer Free Writing Prospectus or any Marketing Materials, in reliance upon and in conformity with written information furnished to the Company by you, or by any Underwriter through you, specifically for use in the preparation thereof; further provided, however, that (i) each Selling Shareholder’s liability under this Section 6 shall be limited to the extent that any misstatements in or omissions from the Registration Statement, or the Prospectus are based on written information furnished for use in the Registration Statement, any Preliminary Prospectus, the Prospectus or any such amendment or supplement, any Issuer Free Writing Prospectus or any Marketing  Materials by such Selling Shareholder; and (ii) in no event shall any Selling Shareholder be liable under the provisions of this Section 6 for any amount in excess of the aggregate amount of proceeds such Selling Shareholder received from the sale of the Securities pursuant to this Agreement.

In addition to its other obligations under this Section 6(b), each Selling Shareholder, severally and not jointly, agrees that, as an interim measure during the pendency of any claim, action, investigation, inquiry or other proceeding arising out of or based upon any statement or omission, or any alleged statement or omission, described in this Section 6(b) for which such Selling Shareholder may be liable, it will reimburse each Underwriter on a monthly basis for all reasonable legal fees or other expenses incurred in connection with investigating or defending any such claim, action, investigation, inquiry or other proceeding, notwithstanding the absence of a judicial determination as to the propriety and enforceability of such Selling Shareholder’s obligation to reimburse the Underwriters for such expenses and the possibility that such payments might later be held to have been improper by a court of competent jurisdiction. To the extent that any such interim reimbursement payment is so held to have been improper, the Underwriter that received such payment shall promptly return it to the party or parties that made such payment, together with interest, compounded daily, determined on the basis of the prime rate (or other commercial lending rate for borrowers of the highest credit standing) announced from time to time by U.S. Bank (the “Prime Rate”). Any such interim reimbursement payments which are not made to an Underwriter within 30 days of a request for reimbursement shall bear interest at the Prime Rate from the date of such request. This indemnity agreement shall be in addition to any liabilities which each Selling Shareholder may otherwise have.

(c)                                  Each Underwriter will indemnify and hold harmless the Company and each Selling Shareholder against any losses, claims, damages or liabilities to which the Company and the Selling Shareholders may become subject, under the Act or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of such Underwriter), 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, the Time of Sale Disclosure Package, the 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

26

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, the Time of Sale Disclosure Package, the Prospectus, or any such amendment or supplement, or any Issuer Free Writing Prospectus, in reliance upon and in conformity with written information furnished to the Company by you, or by such Underwriter through you, specifically for use in the preparation thereof, and will reimburse the Company and the Selling Shareholders for any legal or other expenses reasonably incurred by the Company or any such Selling Shareholder in connection with investigating or defending against any such loss, claim, damage, liability or action.

(d)                                 In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to this Section 6, such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for (i) the fees and expenses of more than one separate firm (in addition to any local counsel) for all Underwriters and all persons, if any, who control any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and (ii) the fees and expenses of more than one separate firm (in addition to any local counsel) for the Company, its directors, its officers who sign the Registration Statement and each person, if any, who controls the Company within the meaning of either such Section 15 of the Securities Act or Section 20 of the Exchange Act. In the case of any such separate firm for the Underwriters and such control persons of any Underwriters, such firm shall be designated in writing by a majority of the Representatives. In the case of any such separate firm for the Company, and such directors, officers and control persons of the Company, such firm shall be designated in writing by the Company. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified

27

party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding.

(e)                                  If the indemnification provided for in this Section 6 is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a) or (b) above, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Selling Shareholders on the one hand and the Underwriters on the other hand from the offering of the Securities or (ii) 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 and the Selling Shareholders on the one hand and the Underwriters on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company, each Selling Shareholder and the Underwriters shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities (before deducting expenses) received by the Company and the Selling Shareholders bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover of the Prospectus. The relative fault of the Company, each Selling Shareholder and the Underwriters, as the case may be, 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, by the Selling Shareholders or by the Underwriters, as the case may be, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Underwriters’ respective obligations to contribute pursuant to this subsection 6(e) are several in proportion to the respective number of Securities they have purchased hereunder, and not joint.

The Company, the Selling Shareholders and the Underwriters agree that it would not be just and equitable if contributions pursuant to this subsection 6(e) were to be 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 in the first sentence of this subsection 6(e). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in the first sentence of this subsection 6(e) shall be deemed to include, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending against any action or claim which is the subject of this subsection 6(e). Notwithstanding the provisions of this subsection 6(e), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public, exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of any untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of

28

Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

(g)                                 The obligations of the Company and the Selling Shareholders under this Section 6 shall be in addition to any liability which the Company and the Selling Shareholders may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Underwriter within the meaning of the Act; and the obligations of the Underwriters under this Section 6 shall be in addition to any liability that the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each director of the Company (including any person who, with his consent, is named in the Registration Statement as about to become a director of the Company), to each officer of the Company who has signed the Registration Statement and to each person, if any, who controls the Company or any Selling Shareholder within the meaning of the Act.

(h)                                 The Underwriters severally confirm and the Company and each Selling Shareholder severally acknowledge that the statements with respect to the public offering of the Securities by the Underwriters set forth on the cover page of the Prospectus, the concession and reallowance figures appearing in the second paragraph under the caption “Underwriting” in  the Prospectus, and the information contained in the table at the end of the first paragraph under the caption “Underwriting” in the Prospectus are correct and constitute the only information concerning such Underwriters furnished in writing to the Company by or on behalf of the Underwriters specifically for inclusion in the Registration Statement, any Preliminary Prospectus, the Time of Sale Disclosure Package, the Prospectus or any Issuer Free Writing Prospectus.

7.                                       Representations and Agreements to Survive Delivery. All representations, warranties, and agreements of the Company and each Selling Shareholder herein or in certificates delivered pursuant hereto, and the agreements of the several Underwriters, the Company and each Selling Shareholder contained in Section 6 hereof, shall remain operative and in full force and effect regardless of any investigation made by or on behalf of any Underwriter or any controlling person thereof, or the Company or any of its officers, directors, or controlling persons, or any Selling Shareholders or any controlling person thereof, and shall survive delivery of, and payment for, the Securities to and by the Underwriters hereunder.

8.                                       Substitution of Underwriters.

(a)                                  If any Underwriter or Underwriters shall fail to take up and pay for the amount of Firm Shares agreed by such Underwriter or Underwriters to be purchased hereunder, upon tender of such Firm Shares in accordance with the terms hereof, and the amount of Firm Shares not purchased does not aggregate more than 10% of the total amount of Firm Shares set forth in Schedule II hereto, the remaining Underwriters shall be obligated to take up and pay for (in proportion to their respective underwriting obligations hereunder as set forth in Schedule II hereto except as may otherwise be determined by you) the Firm Shares that the withdrawing or defaulting Underwriters agreed but failed to purchase.

(b)                                 If any Underwriter or Underwriters shall fail to take up and pay for the amount of Firm Shares agreed by such Underwriter or Underwriters to be purchased hereunder,

29

upon tender of such Firm Shares in accordance with the terms hereof, and the amount of Firm Shares not purchased aggregates more than 10% of the total amount of Firm Shares set forth in Schedule II hereto, and arrangements satisfactory to you for the purchase of such Firm Shares by other persons are not made within 36 hours thereafter, this Agreement shall terminate. In the event of any such termination neither the Company nor any Selling Shareholder shall be under any liability to any Underwriter (except to the extent provided in Section 4(a)(viii), Section 4(b)(ii) and Section 6 hereof) nor shall any Underwriter (other than an Underwriter who shall have failed, otherwise than for some reason permitted under this Agreement, to purchase the amount of Firm Shares agreed by such Underwriter to be purchased hereunder) be under any liability to the Company or the Selling Shareholders (except to the extent provided in Section 6 hereof).

If Firm Shares to which a default relates are to be purchased by the non-defaulting Underwriters or by any other party or parties, the Representatives or the Company shall have the right to postpone the First Closing Date for not more than seven business days in order that the necessary changes in the Registration Statement, in the Time of Sale Disclosure Package, in the Prospectus or in any other documents, as well as any other arrangements, may be effected. As used herein, the term “Underwriter” includes any person substituted for an Underwriter under this Section 8.

9.                                                                                       Effective Date of this Agreement and Termination.

(a)                                  This Agreement shall become effective at 10:00 a.m., Central time, on the first full business day following the effective date of the Registration Statement, or at such earlier time after the effective time of the Registration Statement as you in your discretion shall first release the Securities for sale to the public; provided, that if the Registration Statement is effective at the time this Agreement is executed, this Agreement shall become effective at such time as you in your discretion shall first release the Securities for sale to the public. For the purpose of this Section, the Securities shall be deemed to have been released for sale to the public upon release by you of an electronic communication authorizing commencement of the offering the Securities for sale by the Underwriters or other securities dealers. By giving notice as hereinafter specified before the time this Agreement becomes effective, you, as Representatives of the several Underwriters, or the Company, may prevent this Agreement from becoming effective without liability of any party to any other party, except that the provisions of Section 4(a)(viii), Section 4(b)(ii) and Section 6 hereof shall at all times be effective.

(b)                                 You, as Representatives of the several Underwriters, shall have the right to terminate this Agreement by giving notice as hereinafter specified at any time at or prior to the First Closing Date, and the option referred to in Section 3(b), if exercised, may be cancelled at any time prior to the Second Closing Date, if (i) the Company shall have failed, refused or been unable, at or prior to such Closing Date, to perform any agreement on its part to be performed hereunder, (ii) any other condition of the Underwriters’ obligations hereunder is not fulfilled, (iii) trading on the Nasdaq National Market, New York Stock Exchange or the American Stock Exchange shall have been wholly suspended, (iv) minimum or maximum prices for trading shall have been fixed, or maximum ranges for prices for securities shall have been required, on the Nasdaq National Market, New York Stock Exchange or the American Stock Exchange, by such Exchange or by order of the Commission or any other governmental authority having

30

jurisdiction, (v) a banking moratorium shall have been declared by federal or state authorities, or (vi) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis that, in your reasonable judgment, is material and adverse and makes it impractical or inadvisable to proceed with the completion of the sale of and payment for the Securities. Any such termination shall be without liability of any party to any other party except that the provisions of Section 4(a)(viii), Section 4(b)(ii) and Section 6 hereof shall at all times be effective.

(c)                                  If you elect to prevent this Agreement from becoming effective or to terminate this Agreement as provided in this Section, the Company and an Attorney-in-Fact, on behalf of the Selling Shareholders, shall be notified promptly by you by telephone, confirmed by letter. If the Company elects to prevent this Agreement from becoming effective, you and an Attorney-in-Fact, on behalf of the Selling Shareholders, shall be notified by the Company by telephone, confirmed by letter.

10.                                 Default by One or More of the Selling Shareholders or the Company. If one or more of the Selling Shareholders shall fail at the First Closing Date to sell and deliver the number of Securities which such Selling Shareholder or Selling Shareholders are obligated to sell hereunder, and the remaining Selling Shareholders do not exercise the right hereby granted to increase, pro rata or otherwise, the number of Securities to be sold by them hereunder to the total number of Securities to be sold by all Selling Shareholders as set forth in Schedule I, then the Underwriters may at your option, by notice from you to the Company and the non-defaulting Selling Shareholders, either (a) terminate this Agreement without any liability on the part of any non-defaulting party or (b) elect to purchase the Securities which the Company and the non-defaulting Selling Shareholders have agreed to sell hereunder.

In the event of a default by any Selling Shareholder as referred to in this Section, either you or the Company or, by joint action only, the non-defaulting Selling Shareholders shall have the right to postpone the First Closing Date for a period not exceeding seven days in order to effect any required changes in the Registration Statement, in the Time of Sale Disclosure Package or in the Prospectus or in any other documents or arrangements.

If the Company shall fail at the First Closing Date to sell and deliver the number of Securities which it is obligated to sell hereunder, then this Agreement shall terminate without any liability on the part of any non-defaulting party.

No action taken pursuant to this Section shall relieve the Company or any Selling Shareholders so defaulting from liability, if any, in respect of such default.

11.                                 Notices. Except as otherwise provided herein, all communications hereunder shall be in writing and, if to the Underwriters, shall be mailed or delivered to the Representatives c/o ▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co., ▇▇▇ ▇▇▇▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇, except that notices given to an Underwriter pursuant to Section 6 hereof shall be sent to such Underwriter at the address stated in the Underwriters’ Questionnaire furnished by such Underwriter in connection with this offering; if to the Company, shall be mailed or delivered to it at ▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇ ▇▇▇▇▇▇▇, ▇▇  ▇▇▇▇▇ Attention:  Chief Executive Officer; if to

12.                                 Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and assigns and the controlling persons, officers and directors referred to in Section 6. Nothing in this Agreement is intended or shall be construed to give to any other person, firm or corporation any legal or equitable remedy or claim under or in respect of this Agreement or any provision herein contained.
