(i) The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”) a registration statement, and an amendment or amendments thereto, on Form SB-2 (File No. 333- 128018), including any related preliminary prospectus or prospectuses, for the registration of the Securities under the Securities Act of 1933, as amended (the “1933 Act”), and the rules and regulations promulgated thereunder (the “1933 Act Regulations”), which registration statement and amendment or amendments have been prepared by the Company in

conformity with the requirements of the 1933 Act and the 1933 Act Regulations. The Company will next file with the Commission either (1) prior to the effective date of such registration statement, a further amendment to such registration statement (including the form of final prospectus) or (2) after the effective date of such registration statement, a final prospectus in accordance with Rules 430A and 424(b). In the case of clause (2), the Company has included in such registration statement, as amended at the Effective Date (as defined in (iii) below), all information (other than Rule 430A information) required by the 1933 Act and the 1933 Act Regulations to be included in such registration statement and the Prospectus. The Company will furnish a copy of any amendment to such registration statement, or any registration statement filed pursuant to Rule 462(b) under the 1933 Act (a “462(b) Registration Statement”), to the Representative at least two business days before filing such registration statement amendment, and will not file any other amendment thereto or any Rule 462(b) Registration Statement to which the Representative shall have objected in writing. Each prospectus used before such registration statement became effective is herein called a “Preliminary Prospectus.” Except as the context may otherwise require, such registration statement, as amended, on file with the Commission at the time the registration statement becomes effective (including the prospectus, financial statements, schedules, exhibits and all other documents filed as a part thereof and all information deemed to be a part thereof as of such time pursuant to paragraph (b) of Rule 430A or 462(b) under the 1933 Act), is hereinafter called the “Registration Statement,” and the form of prospectus in the form first filed with the Commission pursuant to Rule 424(b) under the 1933 Act, is hereinafter called the “Prospectus.”

For purposes of this Agreement, all references 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 (“▇▇▇▇▇”).

(ii) The Company meets the requirements for use of Form SB-2. Neither the Commission nor any state regulatory authority has issued any order suspending the effectiveness of the Registration Statement, any Rule 462(b) Registration Statement or any post-effective amendment thereto, and no proceedings for a stop order suspending the effectiveness of the Registration Statement have been instituted or are pending or to the Company’s knowledge, threatened.

(iii) At the respective times the Registration Statement became, any Rule 462(b) Registration Statement and any post-effective amendments thereto become effective (the “Effective Date”) and at the Closing Date (and, if any Option Shares are purchased, at the Option Closing Date),

the Registration Statement, the Rule 462(b) Registration Statement and any amendments and supplements thereto complied and will comply in all material respects with the requirements of the 1933 Act and the 1933 Act Regulations and did not and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. Neither the Prospectus nor any amendments or supplements thereto, at the respective times the Prospectus or any such amendment or supplement was issued or will be issued and at the Closing Date (and, if any Option Shares are purchased, at the Option Closing Date), included or will include an untrue statement of a material fact or omitted or will 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 in this subsection shall not apply to statements in or omissions from the Registration Statement or Prospectus made in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representative expressly for use in the Registration Statement (or any amendment thereto) or the Prospectus (or any amendment or supplement thereto).

Each Preliminary Prospectus and the Prospectus filed as part of the Registration Statement as originally filed or as part of any amendment thereto complied or will comply when so filed in all material respects with the 1933 Act Regulations and each Preliminary Prospectus and the Prospectus delivered to the Underwriters for use in connection with this offering was or will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to ▇▇▇▇▇, except to the extent permitted by Regulation S-T and the 1933 Act Regulations.

(m) Such Selling Shareholder acknowledges that the Underwriters and, for purposes of the opinion to be delivered pursuant to Section 8(d) hereof, Underwriters’ Counsel, will rely upon the accuracy and truthfulness of the foregoing representations and hereby consents to such reliance.

3. Purchase, Sale and Delivery of the Securities.

(a) On the basis of the representations, warranties, covenants and agreements herein contained, but subject to the terms and conditions herein set forth, the Company agrees to sell to each Underwriter, and each Underwriter, severally and not jointly, agrees to purchase from the Company at a price of $ per share of Common Stock, that number of Firm Shares set forth in Schedule A opposite the name of such Underwriter.

(b) Payment of the purchase price and delivery of certificates for the Firm Shares shall be made at the offices of [▇▇▇▇▇▇ & ▇▇▇▇▇▇, L.L.P., ▇▇▇▇ ▇▇▇▇, ▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇], or at such other place as shall be agreed upon by the Representative and the Company. Such delivery and payment shall be made at 10:00 a.m. (New York City time) on , 2005, or at such other time and date as shall be agreed upon by the Representative and the Company, but not more than three business days after the foregoing date (such time and date of payment and delivery being herein called the “Closing Date”). Delivery of the Firm Shares shall be made to the Representative for the respective accounts of the several Underwriters against payment by the several Underwriters through the Representative of the respective aggregate purchase prices of the Firm Shares being sold by the Company, to or upon the order of, the Company by wire transfer payable in same day funds to the accounts specified by the Company. Delivery of the Firm Shares shall be made through the facilities of The Depository Trust Company unless the Representative shall otherwise instruct.

(c) In addition, on the basis of the representations, warranties, covenants and agreements herein contained, but subject to the terms and conditions herein set forth, the Company and the Selling Shareholders hereby grant an option to the Underwriters to purchase all or any part of the Option Shares at the same purchase price per share as the Underwriters shall pay for the Firm Shares. Said option

may be exercised only to cover over-allotments in the sale of the Firm Shares by the Underwriters. Said option may be exercised from time to time on or before the 30th day after the date of the Prospectus upon written or telegraphic notice by the Representative to the Company setting forth the number of shares of the Option Shares as to which the several Underwriters are exercising the option and any Option Closing Date. The number of the Option Shares to be purchased by each Underwriter shall be the same percentage of the total number of shares of the Option Shares to be purchased by the several Underwriters as such Underwriter is purchasing of the Firm Shares, subject to such adjustments as the Representative in its absolute discretion shall make to eliminate any fractional shares. The maximum number of Option Shares to be sold by the Company and the Selling Shareholders is 412,500 shares and 412,500 shares, respectively.

(d) If the option provided for in Section (c) hereof is exercised after the third business day prior to the Closing Date, the Company and the Selling Shareholders will deliver the Option Shares (at the expense of the Company) to the Representative at [▇▇▇▇▇▇ & ▇▇▇▇▇▇, L.L.P., ▇▇▇▇ ▇▇▇▇, ▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇], on the date specified by the Representative which shall be within three business days after exercise of said option (each such date and time of payment and delivery being herein called an “Option Closing Date”), against payment by the several Underwriters through the Representative thereof to, or upon the order of, the Company and the Selling Shareholders by wire transfer payable in same day funds to the accounts specified by the Company and the Selling Shareholders. Delivery of the Option Shares shall be made through facilities of The Depository Trust Company unless the Representative shall otherwise instruct. Each Selling Shareholder shall deliver to the transfer agent and registrar of the Common Stock (the “Transfer Agent”) any certificates evidencing shares of Common Stock (to the extent that the Transfer Agent requires delivery of such certificates) necessary to cause the Transfer Agent to arrange for the delivery of the Option Shares in accordance with the provisions of this Section (d), authorize and instruct the Transfer Agent to cancel any such certificates and each Selling Shareholder shall authorize the Transfer Agent to arrange for the delivery of the Option Shares in accordance with the provisions of this Section 3(d). If settlement for the Option Shares occurs after the Closing Date, the Company and the Selling Shareholders will deliver to the Representative on any settlement date for the Option Shares, and the obligation of the Underwriters to purchase the Option Shares shall be conditioned upon receipt of, supplemental opinions, certificates and letters confirming as of such date the opinions, certificates and letters delivered on the Closing Date pursuant to Section 8 hereof. Each Selling Shareholder hereby agrees that (i) it will pay all stock transfer taxes, stamp duties and other similar taxes, if any, payable upon the sale or delivery of the Option Shares to be sold by such Selling Shareholder to the several Underwriters, or otherwise in connection with the performance of such Selling Shareholder’s obligations hereunder and (ii) the Custodian is authorized to deduct for such payment any such amounts from the proceeds to such Selling Shareholder hereunder and to hold such amounts for the account of such Selling Shareholder with the Custodian under the Custody Agreement.

4. Public Offering of the Securities. It is understood that the several Underwriters propose to offer the Securities for sale to the public as set forth in the Prospectus.

5. Covenants and Agreements of the Company. The Company agrees with each of the several Underwriters that:

(a) The Company will use its reasonable best efforts to cause the Registration Statement, if not effective at the date and time that this Agreement is executed and delivered by the parties hereto (the “Execution Time”), and any amendment thereof, to become effective as promptly as possible. Prior to the termination of the offering of the Securities, the Company will not file any amendment to the Registration Statement or supplement to the Prospectus or any Rule 462(b) Registration Statement unless the Company has furnished the Representative a copy for their review prior to filing and will not file any such proposed amendment or supplement to which the Representative reasonably objects. Subject to the foregoing sentence, if the Registration Statement has become or becomes effective pursuant to Rule 430A, or filing of the Prospectus is otherwise required under Rule 424(b), the Company will cause the Prospectus, properly completed, and any supplement thereto to be filed with the Commission pursuant to the applicable paragraph of Rule 424(b) within the time period prescribed therein and will provide evidence satisfactory to the Representative of such timely filing. The Company will promptly advise the Representative (i) when the Registration Statement, if not effective at the Execution Time, shall have become effective, (ii) when the Prospectus, and any supplement thereto, shall have been filed (if required) with the Commission pursuant to Rule 424(b) or when any Rule 462(b) Registration Statement shall have been filed with the Commission, (iii) when, prior to termination of the offering of the Securities, any amendment to the Registration Statement shall have been filed or become effective, (iv) of any request by the Commission or its staff for any amendment of the Registration Statement, or any Rule 462(b) Registration Statement, or for any supplement to the Prospectus or of any additional information, (v) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or the institution or threatening of any proceeding for that purpose and (vi) of the receipt by the Company of any notification with respect to the suspension of the qualification of the Securities for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose. The Company will use its reasonable best efforts to prevent the issuance of any such stop order or the suspension of any such qualification and, if issued, to obtain as soon as possible the withdrawal thereof.

(b) If, at any time when a prospectus relating to the Securities is required to be delivered under the 1933 Act and the 1933 Act Regulations promulgated thereunder, any event occurs as a result of which the Prospectus as then supplemented would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made not misleading, or if it shall be necessary to amend the Registration Statement or supplement the Prospectus to

comply with the 1933 Act and the 1933 Act Regulations promulgated thereunder, the Company promptly will (A) notify the Representative of any such event, (B) prepare and file with the Commission, subject to Section 5(a)(i), an amendment or supplement which will correct such statement or omission or effect such compliance and (C) supply any supplemented Prospectus to each of the Underwriters in such quantities as each such Underwriter may reasonably request.

(c) The Company will endeavor in good faith, in cooperation with the Representative, at or prior to the Effective Date, to qualify the Securities for offering and sale under the securities laws of such jurisdictions as the Representative may designate to permit the continuance of sales and dealings therein for as long as may be necessary to complete the distribution, and shall make such applications, file such documents and furnish such information as may be required for such purpose; provided, however, the Company shall not be required to qualify as a foreign corporation or file a general or limited consent to service of process in any such jurisdiction. In each jurisdiction where such qualification shall be effected, the Company will, unless the Representative agrees that such action is not at the time necessary or advisable, use all reasonable efforts to file and make such statements or reports at such times as are or may reasonably be required by the laws of such jurisdiction to continue such qualification.

(d) As soon as practicable, but in any event not later than 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 occurs (90 days in the event that the end of such fiscal quarter is the end of the Company’s fiscal year), the Company shall make generally available to its security holders, in the manner specified in Rule 158 under the 1933 Act, and to the Representative, an earnings statement which will be in the detail required by, and will otherwise comply with, the provisions of Section 11(a) of the 1933 Act and Rule 158 under the 1933 Act.

(e) During a period of two years from the date hereof, the Company will furnish to its shareholders annual reports (including financial statements audited by independent public accountants) and will deliver to the Representative:

(1) concurrently with furnishing the above-mentioned quarterly reports to its shareholders, statements of income of the Company for each quarter, in the form furnished to the Company’s shareholders and certified by the Company’s principal financial or accounting officer;

(2) concurrently with furnishing the above-mentioned annual reports to its shareholders, a balance sheet of the Company as at the end of the preceding fiscal year, together with statements of operations, shareholders’ equity, and cash flows of the Company for such fiscal year, accompanied by a copy of the report thereon of independent certified public accountants;

(5) every press release and every news item or article of interest to the financial community in respect of the Company or its affiliates which was released and prepared by or on behalf of the Company.

Delivery to the Representative will be deemed to have been made to the extent the Company has filed the above-referenced materials (including those in Section 5(d) above) with the Commission.

(f) For a period of one year from the Closing Date, the Company shall furnish to the Representative, at the Representative’s request and at the Company’s sole expense, on a quarterly basis (i) a readily available list of the securities positions of participants in the Depository Trust Company in the Common Stock and (ii) as provided from the transfer agent to the Company, a list of holders of all of the Company’s securities.

(g) The Company will furnish to the Representative and Underwriters’ Counsel, without charge, at such place as the Representative may designate, signed copies of the Registration Statement (including exhibits thereto) and to each other Underwriter a copy of the Registration Statement (without exhibits thereto) and, so long as delivery of a prospectus by an Underwriter or dealer may be required by the 1933 Act and the 1933 Act Regulations promulgated thereunder, as many copies of each Preliminary Prospectus and the Prospectus and any supplement thereto as the Representative may reasonably request.

(h) At the Execution Time, the Underwriter shall have received an agreement substantially in the form of Exhibit A hereto signed by the persons or entities listed on Schedule D hereto (the “Lock-Up Agreements”). On or before the Closing Date, the Company shall deliver instructions to the Transfer Agent authorizing it to place appropriate stop transfer orders on the Company’s ledgers, subject to the terms and conditions of the Lock-Up Agreements.

(i) The Company will not offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, or file with the Commission a registration statement under the Securities Act relating to, any shares of Common Stock or securities convertible into or exchangeable or exercisable for any shares of Common Stock, or publicly disclose the intention to make any offer, sale, pledge, disposition or filing, without the prior written consent of the Representative for a period of 120 days (“Lock Up Period”) after the Execution Date (as defined herein). The foregoing restriction will not apply to the filing of a registration statement on

Form S-8 under the Securities Act to register securities issuable under the Company’s existing employee benefit plans, issuance of Common Stock upon exercise of an existing option or warrant or conversion of existing preferred stock, or the Company’s granting of awards pursuant to the Company’s existing employee benefit plans.

(j) Prior to the completion of the distribution of the Securities by the Underwriters, neither the Company nor any of its officers or directors nor any of their respective affiliates (within the meaning of the Exchange Act) will take, and will use their reasonable best efforts to prevent any 5% shareholder from taking, directly or indirectly, any action designed to, or which might in the future reasonably be expected to, cause or result in, under the Exchange Act and the rules and regulations thereunder or otherwise, stabilization or manipulation of the price of the Common Stock or any other reference security with respect to the Common Stock, whether to facilitate the sale or resale of the Securities or otherwise, and the Company will, and will use reasonable efforts to cause each of its affiliates to, comply with all applicable provisions of Regulation M in connection with the distribution of the Securities.

(k) The Company shall apply the net proceeds from the sale of the Securities in the manner, and subject to the conditions, set forth under “Use of Proceeds” in the Prospectus. Except as described in the Prospectus, no portion of the net proceeds will be used, directly or indirectly, to acquire any securities issued by the Company.

(l) The Company shall timely file all such reports, forms or other documents as may be required from time to time, under the 1933 Act, the Exchange Act and the rules and regulations promulgated thereunder and all such reports, forms and documents filed will comply as to form and substance in all material respects with the applicable requirements under the 1933 Act, the Exchange Act and the rules and regulations promulgated thereunder.

(m) The Company shall cause the Securities to be listed, subject to notice of issuance, on the American Stock Exchange and shall use its reasonable best efforts to maintain the listing of the Common Stock by the American Stock Exchange for so long as shares of Common Stock are listed on the American Stock Exchange.

6. Covenants and Agreements of the Selling Shareholders. Each Selling Shareholder agrees with each of the several Underwriters that:

(a) The Selling Shareholders shall not, during the Lock-Up Period, without the prior written consent of the Representative, (i) offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, any shares of the Common Stock or securities convertible into or exchangeable or exercisable for any shares of the Common Stock, (ii) enter into a transaction that 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 Common Stock, whether

any of these transactions are to be settled by delivery of the Common Stock or other securities, or (iii) publicly disclose, unless required by law, the intention to make any offer, sale, pledge or disposition or enter into any transaction, swap, hedge or other arrangement. The foregoing sentence shall not apply to (A) the transfer of any shares of Common Stock pursuant to a tender offer, exchange offer, merger, business combination or similar transaction that will result in the holders of the Common Stock outstanding immediately prior to such transaction failing to continue to represent at least 50% percent of the combined voting power of the Common Stock or such surviving or other entity outstanding immediately after such transaction; (B) the sale or disposition of all or substantially all of the Company’s assets (or consummation of any transaction, or series of related transactions, having similar effect); (C) the sale by each of the spouses of the Company’s directors of up to an aggregate of 25,000 shares of Common Stock, owned by such spouse, after the 30-day post-offering stabilization period following the closing of the offering; (D) the delivery by any of the Selling Shareholders (or such Selling Shareholder’s spouse) of Common Stock in fulfillment of the over allotment option referred to in the Registration Statement; (E) the repurchase by the Company from its directors of stock purchase warrants as contemplated by the Registration Statement; (F) any shares of Common Stock issued, or options to purchase Common Stock granted, or transfers to the Company of existing shares of common stock in connection with a “cashless exercise” of options, in accordance with the terms contained in the current stock option plans of the Company; (G) the issuance by the Company of Common Stock upon the conversion or exercise of outstanding securities of the Company exercisable or convertible into shares of Common Stock; (H) the transfer to any trust for the benefit of the undersigned or the undersigned’s immediate family; (I) the transfer by will or intestacy to the undersigned’s legal representative, heir, or legatee. Notwithstanding the foregoing, if (i) the Company issues an earnings release or announces material news, or a material event relating to the Company occurs, during the last 17 days of the Lock-Up Period, or (ii) 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 lock-up restrictions shall continue to apply until the expiration of a 17-day period beginning on the issuance of the earnings release, the announcement of material news, or the occurrence of a material event.

(e) At any Option Closing Date, the Underwriters shall have received the favorable opinion of ▇▇▇▇▇▇ and ▇▇▇▇▇, L.L.P., dated such Option Closing Date, addressed to the Underwriters and in form and substance satisfactory to Underwriters’ Counsel, confirming, as of such Option Closing Date, the statements made by ▇▇▇▇▇▇ and ▇▇▇▇▇, L.L.P. in its opinion delivered on such Closing Date.

(f) Prior to each of the Closing Date and any Option Closing Date, other than as set forth in the Registration Statement or Prospectus, (i) there shall have been no adverse change nor development involving a prospective adverse change in the condition, financial or otherwise, prospects, shareholders’ equity or the business activities of the Company and any of its Subsidiaries taken as a whole, whether or not in the ordinary course of business, from the latest dates as of which such condition is set forth in the Registration Statement and Prospectus; (ii) there shall have been no transaction, not in the ordinary course of business, entered into by the Company or any of its Subsidiaries, from the latest date as of which the financial condition of the Company and its Subsidiaries, taken as a whole, is set forth in the Registration Statement and Prospectus which is adverse to the Company and its Subsidiaries, taken as a whole; (iii) neither the Company or any of its Subsidiaries, shall be in default under any provision of any instrument relating to any outstanding indebtedness; (iv) since the date of the Prospectus,

neither the Company nor any of its Subsidiaries shall have issued any securities (other than the Securities); (v) since the date of the Prospectus and except as in accordance with the conversion of the Company’s 8½% Senior Convertible Preferred Stock, neither the Company nor any of its Subsidiaries shall have declared or paid any dividend or made any distribution in respect of its capital stock of any class; (vi) since the date of the Prospectus, there shall have been no change in the capital stock of the Company, or any material change in the debt (long or short term) or liabilities or obligations of the Company or any of its Subsidiaries (contingent or otherwise); (vii) since the date of the Prospectus, no amount of the assets of the Company or any of its Subsidiaries shall have been pledged or mortgaged; (viii) no actions, suits or proceedings, at law or in equity, shall have been pending or, to the best knowledge of the Company, threatened (or circumstances giving rise to same) against the Company or any of its Subsidiaries, or affecting any of its properties or business, before or by any court or federal, state or foreign commission, board or other administrative agency wherein unfavorable decisions, rulings or findings may have, individually or in the aggregate, a Material Adverse Effect; and (ix) no stop order shall have been issued under the 1933 Act and no proceedings therefor shall have been initiated or, to the best knowledge of the Company, threatened or contemplated by the Commission.

(iv) since the date of the most recent financial statements included in the Prospectus (exclusive of any supplement thereto), there has been no material adverse change in the condition (financial or otherwise), earnings, business, prospects or properties of the Company and its Subsidiaries, taken as a whole, whether or not arising from transactions in the ordinary course of business.

(h) On any Option Closing Date, the Representative shall receive a written certificate executed by each Selling Shareholder, dated as of such Option Closing Date, to the effect that the representations and warranties of such Selling Shareholder in this Agreement are true and correct in all respects as if made on and as of such Option Closing Date and such Selling Shareholder has complied with all the agreements and covenants and satisfied all conditions contained in this Agreement on its part to be performed or satisfied at or prior to such Option Closing Date.

Notice of such cancellation shall be given to the Company in writing or by telephone or facsimile confirmed in writing.

The documents required to be delivered by this Section 8 shall be delivered at the offices of [▇▇▇▇▇▇ & ▇▇▇▇▇▇, L.L.P., ▇▇▇▇ ▇▇▇▇, ▇▇^▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇], on the Closing Date.

9. Reimbursement of Underwriters’ Expenses. If the sale of the Securities provided for herein is not consummated because any condition to the obligations of the Underwriters set forth in Section 8 hereof is not satisfied, because of any termination pursuant to Section 13 hereof or because of any refusal, inability or failure on the part of the Company to perform any agreement herein or comply with any provision hereof other than by reason of a default by any of the Underwriters, the Company will reimburse the Underwriters severally through the Representative on demand for all of its reasonable and accountable out-of-pocket expenses (including reasonable fees and disbursements of counsel) that shall have been incurred by them in connection with the proposed purchase and sale of the Securities.

10. Indemnification and Contribution.

(a) The Company agrees to indemnify and hold harmless each Underwriter, the directors, officers, employees and agents of each Underwriter and each person

who controls any Underwriter within the meaning of either the 1933 Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the 1933 Act, the Exchange Act or other federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the registration statement for the registration of the Securities as originally filed or in any amendment thereof, or in any Preliminary Prospectus or the Prospectus, or in any amendment thereof or supplement thereto, 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 agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Company by or on behalf of any Underwriter through the Representative specifically for inclusion therein. This indemnity agreement will be in addition to any liability which the Company may otherwise have.

(b) Each Selling Shareholder, severally and not jointly, agrees to indemnify and hold harmless each Underwriter, the directors, officers, employees and agents of each Underwriter and each person who controls any Underwriter within the meaning of either the 1933 Act or the Exchange Act, to the same extent as the foregoing indemnity to each Underwriter by the Company in Section 10(a) above, but only with reference to the information contained under the caption “Principal and Selling Shareholders” (except for the percentages relating to the ownership both prior to and after giving effect to the sale of the Option Shares furnished by or on behalf of such Selling Shareholder specifically for inclusion in the documents referred to in the foregoing indemnity; provided, however, that the liability, of a Selling Shareholder pursuant to this subsection (b) hereof shall not exceed the product of the number of Option Shares sold by such Selling Shareholder, and the public offering price set forth in the table on the front cover of the Prospectus (after deducting expenses). This indemnity agreement will be in addition to any liability which any Selling Shareholder may otherwise have.

(c) Each Underwriter severally and not jointly agrees to indemnify and hold harmless the Company, each of its directors, each of its officers who signs the Registration Statement, and each person who controls the Company within the meaning of either the 1933 Act or the Exchange Act and the Selling Shareholders to the same extent as the foregoing indemnities to each Underwriter, but only with reference to written information relating to such Underwriter furnished to the Company by or on behalf of such Underwriter through the Representative specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity

agreement will be in addition to any liability which any Underwriter may otherwise have. The Company and the Selling Shareholders acknowledge that the statements set forth under the heading “Underwriting”, (i) the sentences related to concessions and reallowances and (ii) the paragraph related to stabilization, syndicate covering transactions and penalty bids in any Prospectus or the Registration Statement constitute the only information furnished in writing by or on behalf of the several Underwriters for inclusion in any Prospectus or the Registration Statement.

(d) Promptly after receipt by an indemnified party under this Section 10 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 10, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraphs (a), (b) or (c) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraphs (a), (b) or (c) above. 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. Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an

unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding.

(e) In the event that the indemnity provided in paragraphs (a), (b) or (c) of this Section 10 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Company, the Selling Shareholders, and the Underwriters agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending same) (collectively “Losses”) to which the Company, the Selling Shareholders, and one or more of the Underwriters may be subject in such proportion as is appropriate to reflect the relative benefits received by the Company, the Selling Shareholders and by the Underwriters from the offering of the Securities; provided, however, that in no case shall any Underwriter (except as may be provided in any agreement among underwriters relating to the offering of the Securities) be responsible for any amount in excess of the underwriting discount or commission applicable to the Securities purchased by such Underwriter hereunder and the Selling Shareholders shall not be responsible for any amount in excess of the product of the number of Option Shares sold by such Selling Shareholder, and the public offering price set forth in the table on the front cover of the Prospectus (after deducting expenses). If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Company, the Selling Shareholders and the Underwriters shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company, of the Selling Shareholders and of the Underwriters in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Company shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by it, the benefits received by the Selling Shareholders shall be deemed to be equal to the product of the number of Option Shares sold by such Selling Shareholder, and the public offering price set forth in the table on the front cover of the Prospectus (after deducting expenses), and benefits received by the Underwriters shall be deemed to be equal to the total underwriting discounts and commissions, in each case as set forth on the cover page of the Prospectus. Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Company, the Selling Shareholders or the Underwriters, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company, the Selling Shareholders and the Underwriters agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation that does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (e), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the ▇▇▇▇ ▇▇▇) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 10, each person who controls an Underwriter within the meaning of either

the 1933 Act or the Exchange Act and each director, officer, employee and agent of an Underwriter shall have the same rights to contribution as such Underwriter, and each person who controls the Company within the meaning of either the 1933 Act or the Exchange Act, each officer of the Company and each director of the Company shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this subsection 10 (e).

11. Representations and Indemnities to Survive Delivery. All representations, warranties, agreements, indemnities and other statements of the Company or its officers, the Selling Shareholders and of the Underwriters, contained in this Agreement or contained in certificates of officers of the Company submitted pursuant hereto, shall be deemed to be representations, warranties and agreements as of the Closing Date and as of any Option Closing Date, as the case may be, and such representations, warranties and agreements and the indemnity agreements contained in Section 10 hereof, shall remain operative and in full force and effect regardless of any investigation made by or on behalf of any Underwriter, Selling Shareholder, the Company or any controlling person of any Underwriter or the Company, and shall survive the termination of this Agreement or the issuance, sale and delivery of the Securities to the Underwriters and the Representative, as the case may be.

12. Effective Date. This Agreement shall become effective upon the later of when (i) the Underwriters and the Company shall have received notification of the effectiveness of the Registration Statement or (ii) the execution of this Agreement. If either the public offering price or the purchase price per Security has not been agreed upon prior to 5:00 P.M., New York time, on the fifth full business day after the Registration Statement shall have become effective, this Agreement shall thereupon terminate without liability to the Company or the Underwriters except as herein expressly provided. Until this Agreement becomes effective as aforesaid, it may be terminated by the Company by notifying the Representative or by the Representative by notifying the Company. Notwithstanding the foregoing, the provisions of this Section 12 and of Section 7 hereof shall at all times be in full force and effect.

13. Termination. This Agreement shall be subject to termination in the absolute discretion of the Representative, by notice given to the Company prior to delivery of and payment for the Securities, if at any time prior to such time (i) trading in any securities of the Company shall have been suspended by the Commission or the American Stock Exchange or trading in securities generally on the New York Stock Exchange, the Nasdaq National Market or American Stock Exchange shall have been suspended or limited or minimum prices shall have been established on any of such exchanges or by such system or by order of the Commission, the NASD or any governmental authority, (ii) the Company shall have sustained a loss material or substantial to the Company by fire, flood, accident, hurricane, earthquake, theft, sabotage or other calamity or malicious act which, whether or not such loss shall have been insured, will, in the Representative’s opinion, make it impracticable or inadvisable to proceed with the delivery of the Securities, (iii) a banking moratorium shall have been declared either by federal or New York state authorities, (iv) any domestic or international event or act or occurrence has materially disrupted, or in the Representative’s opinion, will in the immediate future

materially adversely disrupt, the financial markets, (v) any material adverse change in the financial markets shall have occurred, or (vi) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war, or other calamity or crisis the effect of which on financial markets is such as to make it, in the sole judgment of the Representative, impractical or inadvisable to proceed with the offering or delivery of the Securities as contemplated by the Prospectus.

If this Agreement shall be terminated pursuant to any of the provisions hereof (otherwise than pursuant to (i) notification by the Representative as provided in Section 12 hereof or (ii) Section 14 or 15 hereof), or if the sale of the Securities provided for herein is not consummated because any condition to the obligations of the Underwriters set forth herein is not satisfied or because of any refusal, inability or failure on the part of the Company to perform any agreement herein or comply with any provision hereof, the Company will, subject to demand by the Representative, reimburse the Underwriters for all reasonable out-of-pocket expenses (including the reasonable fees and expenses of their counsel), incurred by the Underwriters in connection herewith.

14. Default by an Underwriter. If any one or more Underwriters shall fail to purchase and pay for any of the Securities agreed to be purchased by such Underwriter or Underwriters hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Underwriters shall be obligated severally to take up and pay for (in the respective proportions which the amount of Securities set forth opposite their names in Schedule A hereto bears to the aggregate amount of Securities set forth opposite the names of all the remaining Underwriters) the Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase; provided, however, that in the event that the aggregate amount of Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of the aggregate amount of Securities set forth in Schedule A hereto, the remaining Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Securities, and if such nondefaulting Underwriters do not purchase all the Securities, this Agreement will terminate without liability to any non-defaulting Underwriter or the Company. In the event of a default by any Underwriter as set forth in this Section 14, the Closing Date shall be postponed for such period, not exceeding five business days, as the Representative shall determine in order that the required changes in the Registration Statement and the Prospectus or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Underwriter of its liability, if any, to the Company and any nondefaulting Underwriter for damages occasioned by its default hereunder.

15. Default by the Company. If the Company shall fail on the Closing Date or on any Option Closing Date, as applicable, to sell and deliver the number of Securities which it is obligated to sell hereunder on such date, then this Agreement shall terminate (or, if such default shall occur with respect to any Option Shares to be purchased on an Option Closing Date, the Underwriters may, at the Representative’s option, by notice from the Representative to the Company, terminate the Underwriters’ obligation to purchase Option Shares from the Company on such date) without any liability on the part of any non-defaulting party other than pursuant to Sections 7 and 10 hereof. No action taken

pursuant to this Section 15 shall relieve the Company from liability, if any, in respect of such default.

16. Notices. All notices and communications hereunder, except as herein otherwise specifically provided, shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication.

No purchaser of Securities from any Underwriter shall be deemed to be a successor by reason merely of such purchase.

18. Applicable Law. This Agreement and all questions relating to its validity, interpretation, performance and enforcement shall be governed by and construed in accordance with the laws of the State of New York.
