Neither the Company nor any of its Subsidiaries nor, to the knowledge of the Company, any director, officer, agent, employee or affiliate of the Company or any of its Subsidiaries is currently subject to any U.S. sanctions administered by the Office of Foreign Assets Control of the U.S. Treasury Department (“OFAC”); and the Company will not directly or indirectly use the proceeds of the offering, or lend, contribute or otherwise make available such proceeds to any subsidiary, joint venture partner or other person or entity, for the purpose of financing the activities of any person currently subject to any U.S. sanctions administered by OFAC;

(xxxviii) No relationship, direct or indirect, exists between or among the Company or any of its Subsidiaries, on the one hand, and the directors, officers, shareholders, customers or suppliers of the Company or any of its Subsidiaries, on the other, that is required by the Securities Act or by the Rules and Regulations to be described in the Registration Statement, the Pricing Disclosure Package, and the Prospectus and that is not so described;

(xxxix) No forward-looking statement (within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act) contained in the Registration Statement, the Pricing Disclosure Package, or the Prospectus has been made or reaffirmed without a reasonable basis or has been disclosed other than in good faith;

(xl) Each of the Company’s executive officers and directors and any shareholders who beneficially own 5% or more of the shares of the capital stock of the Company and certain other shareholders, in each case as listed on Schedule III hereto, has executed and delivered lock-up agreements as contemplated by Section 8(l) hereof;

2. Subject to the terms and conditions herein set forth, (a) the Company agrees to sell to each of the Underwriters, and each of the Underwriters agrees, severally and not jointly, to purchase from the Company, at a purchase price per share of $4.0375 (the “Purchase Price”), the

number of Firm Shares (to be adjusted by the Representative so as to eliminate fractional shares) determined by multiplying the aggregate number of Firm Shares to be sold by the Company hereunder by a fraction, the numerator of which is the aggregate number of Firm Shares to be purchased by such Underwriter as set forth opposite the name of such Underwriter in Schedule I hereto and the denominator of which is the aggregate number of Firm Shares to be purchased by all of the Underwriters from the Company hereunder and (b) in the event and to the extent that the Underwriters shall exercise the election to purchase Option Shares as provided below, to sell to each of the Underwriters, and each of the Underwriters agrees, severally and not jointly, to purchase from the Company, at the Purchase Price, the number of Option Shares (to be adjusted by the Representative so as to eliminate fractional shares) determined by multiplying (x) the number of Option Shares as to which such election shall have been exercised by (y) the fraction set forth in clause (a) above.

The Company hereby grants to the Underwriters the right to purchase at their election up to 1,080,000 Option Shares, at the Purchase Price, for the sole purpose of covering over-allotments in connection with the sale of the Firm Shares. The Underwriters may exercise their option to acquire Option Shares in whole or in part only by written notice from the Representative to the Company, given within a period of 30 calendar days after the date of this Agreement and setting forth the aggregate number of Option Shares to be purchased and the date on which such Option Shares are to be delivered, as determined by the Representative but in no event earlier than the Closing Date or, unless the Representative and the Company otherwise agree in writing, earlier than two or later than ten business days after the date of such notice.

3. It is understood that the several Underwriters propose to offer the Firm Shares for sale to the public upon the terms and conditions set forth in the Prospectus.

4. The Company will deliver the Firm Shares to the Representative through the facilities of the Depository Trust Company (“DTC”) for the accounts of the Underwriters, against payment of the aggregate purchase price therefor by wire transfer of federal (same day) funds to the account specified by the Company. The documents to be delivered pursuant to this Agreement shall be delivered to the office of ▇▇▇▇▇▇ & ▇▇▇▇ PC, ▇▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇, ▇▇▇▇▇ ▇▇▇, ▇▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇, at 10:00 A.M., Central time, on March 29, 2010, or at such other time not later than seven full business days thereafter as the Representative and the Company determine, such time being herein referred to as the “Closing Date.” For purposes of Rule 15c6-1 under the Exchange Act, the Closing Date (if later than the otherwise applicable settlement date) shall be the settlement date for payment of funds and delivery of securities for all the Firm Shares.

The time for the delivery of and payment for the Option Shares, being herein referred to as the “Option Closing Date,” which may be the Closing Date, shall be determined by the Representative as provided above. The Company will deliver the Option Shares being purchased on the Option Closing Date to the Representative through the facilities of DTC for the accounts of the Underwriters, against payment of the aggregate purchase price therefor by wire transfer in federal (same day) funds to the account specified by the Company. The documents to be delivered pursuant to this Agreement shall be delivered to the above office of ▇▇▇▇▇▇ & ▇▇▇▇ PC, ▇▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇, ▇▇▇▇▇ ▇▇▇, ▇▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇, at 10:00 A.M., Central time on the Option Closing Date.

5. The Company covenants and agrees with each of the Underwriters as follows:

(a) The Company, subject to Section 5(b), will comply with the requirements of Rule 430A under the Securities Act, and will notify the Representative immediately, and confirm the notice in writing, (i) when any post-effective amendment to the Registration Statement shall become effective, or any supplement to the Prospectus or any amended prospectus shall have been filed, to furnish the Representative with copies thereof, and to file promptly all material required to be filed by the Company with the Commission pursuant to Rule 433(d) under the Securities Act, (ii) of the receipt of any comments from the Commission, (iii) of any request by the Commission for any amendment to the Registration Statement or any amendment or supplement to the Prospectus or for additional information, and (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any order preventing or suspending the use of any Preliminary Prospectus, or of the suspension of the qualification of the Shares for offering or sale in any jurisdiction, or of the initiation or threatening of any proceedings for any of such purposes. The Company will promptly effect the filings necessary pursuant to Rule 424(b) under the Securities Act and will take such steps as it deems necessary to ascertain promptly whether the form of prospectus transmitted for filing under Rule 424(b) was received for filing by the Commission and, in the event that it was not, it will promptly file such prospectus. The Company will make every reasonable effort to prevent the issuance of any stop order and, if any stop order is issued, to obtain the lifting thereof at the earliest possible moment.

(b) The Company will (i) give the Representative notice of its intention to file or prepare any amendment to the Registration Statement (including any filing under Rule 462(b) under the Securities Act), or any amendment, supplement or revision to the Prospectus, or any Issuer Free Writing Prospectus, (ii) furnish the Representative with copies of any such documents a reasonable amount of time prior to such proposed filing or use, as the case may be, and (iii) not file or use any such document to which the Representative or counsel for the Underwriters shall reasonably object.

(c) The Company will use its best efforts to qualify the Shares for offering and sale under the securities laws of such jurisdictions as the Representative may reasonably request and to comply with such laws so as to permit the continuance of sales and dealings therein in such jurisdictions for as long as may be necessary to complete the distribution of the Shares, provided that nothing in this Section 5(c) shall require the Company to qualify as a foreign corporation in any jurisdiction in which it is not already so qualified, or to file a general consent to service of process in any jurisdiction. In each jurisdiction in which the Shares have been so qualified, the Company will file such statements and reports as may be required by the laws of such jurisdiction to continue such qualification in effect for a period of not less than one year from the effective date of the Registration Statement and any Rule 462(b) Registration Statement. The Company will also supply the Underwriters with such information as is necessary for the determination of the legality of the Shares for investment under the laws of such jurisdiction as the Underwriters may request.

(d) The Company will deliver to the Representative upon request, without charge, signed copies of the Initial Registration Statement as originally filed with the Commission, any Rule 462(b) Registration Statement and of each amendment to each (including

(e) The Company has delivered to each Underwriter, without charge, as many written and electronic copies of each Preliminary Prospectus and Issuer Free Writing Prospectus as such Underwriter reasonably requested, and the Company hereby consents to the use of such copies for purposes permitted by the Securities Act. The Company will furnish to each Underwriter, without charge, prior to 5:00 P.M. Eastern on the business day next succeeding the date of this Agreement and from time to time thereafter during the period when the Prospectus is required to be delivered in connection with sales of the Shares under the Securities Act or the Exchange Act or in lieu thereof, the notice referred to in Rule 173(a) under the Securities Act, such number of written and electronic copies of the Prospectus (as amended or supplemented) as such Underwriter may reasonably request. The Prospectus and any amendments or supplements thereto, and any Issuer Free Writing Prospectus, furnished to the Underwriters will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to ▇▇▇▇▇, except to the extent permitted by Regulation S-T.

(f) The Company will comply with the Securities Act and the Rules and Regulations so as to permit the completion of the distribution of the Shares as contemplated in this Agreement and in the Prospectus. If at any time when, in the opinion of counsel for the Underwriters, a prospectus is required to be delivered in connection with sales of the Shares under the Securities Act or the Exchange Act (or in lieu thereof, the notice referred to in Rule 173(a) under the Securities Act), any event shall occur or condition shall exist as a result of which it is necessary, in the opinion of counsel for the Underwriters or for the Company, to amend the Registration Statement or amend or supplement the Prospectus in order that the Prospectus will not include any untrue statements of a material fact or omit to state a material fact necessary in order to make the statements therein not misleading in the light of the circumstances existing at the time it (or in lieu thereof, the notice referred to in Rule 173(a) under the Securities Act) is delivered to a purchaser, or if it shall be necessary, in the opinion of either such counsel, at any such time to amend the Registration Statement or amend or supplement the Prospectus in order to comply with the requirements of the Securities Act or the Rules and Regulations, the Company will promptly prepare and file with the Commission, subject to Section 5(b), such amendment or supplement as may be necessary to correct such statement or omission or to make the Registration Statement or the Prospectus comply with such requirements, and the Company will furnish to the Underwriters such number of written and electronic copies of such amendment or supplement as the Underwriters may reasonably request. The Company will provide the Representative with notice of the occurrence of any event during the period specified above that may give rise to the need to amend or supplement the Registration Statement or the Prospectus as provided in the preceding sentence promptly after the occurrence of such event.

(g) The Company will make generally available (within the meaning of Section 11(a) of the Securities Act) to its security holders and to the Representative as soon as practicable, but not later than 45 days after the end of its fiscal quarter in which the first anniversary date of the effective date of the Registration Statement occurs, an earnings statement (in form complying with the provisions of Rule 158 under the Securities Act) covering a period of at least twelve consecutive months beginning after the effective date of the Registration Statement.

(h) The Company will use the net proceeds received by it from the sale of the Shares in the manner specified in the Pricing Prospectus under the heading “Use of Proceeds.”

(j) During a period of 90 days from the date of the Prospectus, the Company will not, without the prior written consent of the Representative, (i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend or otherwise transfer or dispose of, directly or indirectly, any Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock or file any registration statement under the Securities Act with respect to any of the foregoing, or (ii) enter into any swap or other agreement that transfers, in whole or in part, directly or indirectly, any of the economic consequences of ownership of Common Stock, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise, other than (1) the Shares to be sold hereunder, (2) the issuance of options to acquire shares of Common Stock or shares of restricted stock granted pursuant to the Company’s benefit plans existing on the date hereof that are referred to in the Prospectus, as such plans may be amended, provided that such options or shares of restricted stock granted during the 90-day period referred to above shall not be vested or exercisable within such 90-day period, or (3) the issuance of shares of Common Stock upon the exercise of any such options or warrants outstanding on the date hereof. Notwithstanding the foregoing, if (A) during the period that begins on the date that is 15 calendar days plus three (3) business days before the last day of the 90-day restricted period and ends on the last day of the 90-day restricted period, the Company issues an earnings release or material news or a material event relating to the Company occurs, or (B) prior to the expiration of the 90-day restricted period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the 90-day restricted period, the restrictions set forth herein will continue to apply until the expiration of the date that is 15 calendar days plus three (3) business days after the date on which the earnings release is issued or the material news or event related to the Company occurs. The Company shall promptly notify the Representative of any earnings release, news or event that may give rise to an extension of the initial 90-day restricted period.

(k) The Company agrees to enforce its rights, if any, under its existing registration rights agreements and shareholders’ agreements, if any, to restrict the transfer of securities within the 90-day period following the Closing Date.

(l) The Company, during the period when the Prospectus is required to be delivered in connection with sales of the Shares under the Securities Act or the Exchange Act (or

in lieu thereof, the notice referred to in Rule 173(a) under the Securities Act), will file all documents required to be filed with the Commission pursuant to the Exchange Act within the time periods required by the Exchange Act and the rules and regulations of the Commission thereunder.

(m) The Company will file with the Commission such information on Form 10-Q or Form 10-K as may be required pursuant to Rule 463 under the Securities Act.

(o) If the Company elects to rely upon Rule 462(b) under the Securities Act, the Company will file a Rule 462(b) Registration Statement with the Commission in compliance with Rule 462(b) by 10:00 P.M., Washington, D.C. time, on the date of this Agreement, and at the time of filing either to pay to the Commission the filing fee for the Rule 462(b) Registration Statement or to give irrevocable instructions for the payment of such fee pursuant to Rule 111(b) under the Securities Act.

6. (a) The Company represents and agrees that, without the prior consent of the Representative, it has not made and will not make any offer relating to the Shares that would constitute a “free writing prospectus” as defined in Rule 405 under the Securities Act; each Underwriter represents and agrees that, without the prior consent of the Company and the Representative, it has not made and will not make any offer relating to the Shares that would constitute a free writing prospectus; any such free writing prospectus the use of which has been consented to by the Company and the Representative is listed on Schedule II hereto;

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

(c) The Company agrees that if at any time following issuance of an Issuer Free Writing Prospectus any event occurred or occurs as a result of which such Issuer Free Writing Prospectus would conflict with the information in the Registration Statement, the Pricing Disclosure Package or the Prospectus or would include an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in light of the circumstances then prevailing, not misleading, the Company will give prompt notice thereof to the Representative and, if requested by the Representative, will prepare and furnish without charge to each Underwriter an Issuer Free Writing Prospectus or other document which will correct such conflict, statement or omission; provided, that this representation and warranty shall not apply to any statements or omissions in an Issuer Free Writing Prospectus made in reliance

upon and in strict conformity with information furnished in writing to the Company by an Underwriter through the Representative expressly for use therein.

7. The Company covenants and agrees with the several Underwriters that, subject to Section 12, whether or not the transactions contemplated by this Agreement are consummated, the Company will pay or cause to be paid all expenses incident to the performance of its obligations under this Agreement, including: (i) the fees, disbursements and expenses of ▇▇▇▇▇▇ Brand LLP, counsel for the Company, ▇▇▇▇ ▇▇▇▇▇ LLP, the independent certified public accountants, and other advisors; (ii) the listing or qualification of the Shares for trading on a national securities exchange; (iii) the printing and mailing of this agreement and related documents; (iv) the issuance, transfer, and delivery of the Shares including issue and transfer taxes, if any; (v) the qualification, registration or exemption, if required, of the Shares under the securities laws of those states in which the Underwriters determine to offer the Shares, including the costs of preparing, printing, or mailing “Blue Sky” surveys or filings and the reasonable fees and disbursements of counsel to the Underwriters in connection therewith; (vi) any COBRA desk or other filings with FINRA; (vii) the Company’s travel in connection with “road show” informational meetings and presentations for the brokerage community and institutional investors; and (viii) registrar and transfer agent fees.

Each Underwriter will pay its own fees and expenses in connection with the offering contemplated hereby (other than reasonable counsel fees and disbursements with respect to “Blue Sky” related matters) to the extent that such fees and expenses, together with such fees and expenses of the other Underwriters, are, in the aggregate, in excess of $80,000.

8. The several obligations of the Underwriters hereunder to purchase the Shares on the Closing Date or each Option Closing Date, as the case may be, are subject to the performance by the Company of its obligations hereunder and to the following additional conditions:

9. (a) The Company agrees to indemnify and hold harmless each Underwriter and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Securities Act or Section 20(a) of the Exchange Act against any and all losses, liabilities, claims, damages and expenses whatsoever as incurred (including without limitation, reasonable attorneys’ fees and any and all reasonable expenses whatsoever incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim whatsoever, and any and all amounts paid in settlement of any claim or litigation), joint or several, to which they or any of them may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such losses, liabilities, claims, damages or expenses (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 Initial Registration Statement, as originally filed or any amendment thereof, the Registration Statement, or any post-effective amendment thereof, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or in any supplement thereto or amendment thereof, any Issuer Free Writing Prospectus, or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act, 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; provided, that the Company will not be liable to the extent that any such loss, liability, claim, damage or expense arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made in the Initial Registration Statement, as originally filed or any amendment thereof, the Registration Statement, or any post-effective amendment thereof, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or in any supplement thereto or amendment thereof, or any Issuer Free Writing Prospectus in reliance upon and in strict conformity with written information furnished to the Company by or on behalf of any Underwriter through the Representative expressly for use therein, it being understood and agreed that the only such information furnished by any Underwriter is the information described as such in Section 9(b) below.

(b) Each Underwriter severally, and not jointly, agrees to indemnify and hold harmless the Company, each of the directors of the Company, each of the officers of the Company who shall have signed the Registration Statement, and each other person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20(a) of the Exchange Act, against any losses, liabilities, claims, damages and expenses whatsoever as incurred (including without limitation, reasonable attorneys’ fees and any and all reasonable expenses whatsoever incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim whatsoever, and any and all amounts paid in settlement of any claim or litigation), joint or several, to which they or any of them may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such losses, liabilities, claims, damages or expenses (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 Initial Registration Statement, as originally filed or any amendment thereof, the Registration Statement, or any post-effective amendment thereof, or any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or in any supplement thereto or amendment thereof, or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that any such loss, liability, claim, damage or expense 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 strict conformity with written information furnished to the Company by or on behalf of such Underwriter through the Representative expressly for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the following information in the Prospectus furnished on behalf of each Underwriter: the concession and reallowance figures appearing in the “Commissions and Expenses” paragraph under the caption “Underwriting” and the information contained under the subheading “Stabilization” under the caption “Underwriting”.

(c) Promptly after receipt by an indemnified party under Section 9(a) or 9(b) of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such Section, notify each party against whom indemnification is to be sought in writing of the commencement thereof (but the failure so to notify an indemnifying party shall not relieve it from any liability which it may have under this Section 9). In case any such action is brought against any indemnified party, and it notifies an indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein, and jointly with any other indemnifying party similarly notified, to the extent it may elect by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnified party). Notwithstanding the foregoing, the indemnified party or parties shall have the right to employ its or their own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of such indemnified party or parties unless (i) the employment of such counsel shall have been authorized in writing by one of the indemnifying parties in connection with the defense of such action, (ii) the indemnifying parties shall not have employed counsel to have charge of the defense of such action within a reasonable time after notice of commencement of the action, or (iii) such indemnified party or parties shall have reasonably concluded that there may be defenses available to it or them which are different from or additional to those available to one or all of

the indemnifying parties (in which case the indemnifying parties shall not have the right to direct the defense of such action on behalf of the indemnified party or parties), in any of which events such fees and expenses shall be borne by the indemnifying parties. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, which counsel, in the event of indemnified parties under Section 9(a), shall be selected by the Representative. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

(d) If the indemnification provided for in this Section 9 is unavailable to or insufficient to hold harmless an indemnified party under Sections 9(a) or 9(b) in respect of any losses, liabilities, claims, damages or expenses (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, liabilities, claims, damages or expenses (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other from the offering of the Shares. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other from the offering of the Shares shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or the Underwriters on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section 9(d) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 9(d). The amount paid or payable by an indemnified party as a result of the losses, liabilities, claims, damages or expenses (or actions in respect thereof) referred to above in this Section 9(d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified

party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 9(d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission.

No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this Section 9(d) to contribute are several in proportion to their respective underwriting obligations and not joint.

(e) The obligations of the parties to this Agreement contained in this Section 9 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

10. If any Underwriter or Underwriters default in its or their obligations to purchase Shares hereunder on the Closing Date or any Option Closing Date (the “Defaulted Shares”) and the aggregate number of Defaulted Shares does not exceed 10% of the total number of Shares that the Underwriters are obligated to purchase on such Closing Date or Option Closing Date, as the case may be, the Representative may make arrangements satisfactory to the Company for the purchase of the Defaulted Shares by other persons, including any of the Underwriters, but if no such arrangements are made by such Closing Date or Option Closing Date, as the case may be, the non-defaulting Underwriters shall be obligated severally, in proportion to their respective commitments hereunder, to purchase the Defaulted Shares on such Closing Date or Option Closing Date, as the case may be. If any Underwriter or Underwriters so default and the aggregate number of Defaulted Shares exceeds 10% of the total number of Shares that the Underwriters are obligated to purchase on such Closing Date or Option Closing Date, as the case may be, and arrangements satisfactory to the Representative and the Company for the purchase of such Defaulted Shares by other persons are not made within 36 hours after such default, this Agreement will terminate, subject to the provisions of Section 12, without liability on the part of any non-defaulting Underwriter or the Company, except as provided in Section 12. Nothing herein will relieve a defaulting Underwriter from liability for its default.

In the event of any such default which does not result in a termination of this Agreement, either the Representative or the Company shall have the right to postpone the Closing Date or the relevant Option Closing Date, as the case may be, for a period not exceeding seven days in order to effect any required changes in the Registration Statement or Prospectus or in any other documents or arrangements. As used in this Agreement, the term “Underwriter” includes any person substituted for an Underwriter under this Section 10.

11. Notwithstanding anything herein contained, this Agreement (or the obligations of the several Underwriters with respect to any Option Shares which have yet to be purchased) may be terminated, subject to the provisions of Section 12, in the absolute discretion of the Representative, by notice given to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date or the Option Closing Date, as the case may be, (a) trading generally on the NASDAQ Global Market shall have been suspended or materially

limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by such system or by order of the Commission, the FINRA or any other governmental authority, (b) trading of the Company’s Common Stock on the NASDAQ Global Market shall have been suspended, (c) a general moratorium on commercial banking activities in New York or California shall have been declared by the Banking Regulatory Authorities or a new restriction materially adversely affecting the distribution of the Firm Shares or the Option Shares, as the case may be, shall have become effective, (d) if there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the Preliminary Prospectus, the Pricing Disclosure Package or the Prospectus, any Material Adverse Effect, or (e) there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Representative, impracticable or inadvisable to market the Shares to be delivered on the Closing Date or Option Closing Date, as the case may be, or to enforce contracts for the sale of the Shares.

If this Agreement is terminated pursuant to this Section 11, such termination will be without liability of any party to any other party except as provided in Section 12 hereof.

12. The respective indemnities, agreements, representations, warranties and other statements of the Company or its officers and of the several Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the Company or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Shares. If this Agreement is terminated pursuant to Sections 8, 10, or 11 or if for any reason the purchase of any of the Shares by the Underwriters is not consummated, the Company shall remain responsible for the expenses to be paid or reimbursed by it pursuant to Section 7, the respective obligations of the Company and the Underwriters pursuant to Section 9 and the provisions of Sections 12, 13, and 16 shall remain in effect and, if any Shares have been purchased hereunder the representations and warranties in Section 1 and all obligations under Section 5, and Section 6 shall also remain in effect. Whether or not the offering contemplated hereby is consummated, the Company also shall reimburse the Underwriters for an amount not to exceed $80,000 (plus the amount of any “Blue Sky” related fees or disbursements referenced in the proviso to this sentence) of the Underwriters’ reasonable, accountable out-of-pocket expenses, including fees and expenses of counsel to the Underwriters, all due diligence, mailing, telephone, travel, clerical or other costs incurred or to be incurred by the Underwriters or by its sales personnel in connection with the offering contemplated hereby upon invoice; provided that, in addition to foregoing, the reasonable fees and disbursements of counsel to the Underwriters in connection with any “Blue Sky” related qualification, registration, exemption, survey or filing shall be separately billed to the Company and shall be paid by the Company. Each Underwriter will pay its own fees and expenses in connection with the offering contemplated hereby (other than reasonable counsel fees and disbursements with respect to “Blue Sky” related matters) to the extent that such fees and expenses, together with such fees and expenses of the other Underwriters, are, in the aggregate, in excess of $80,000.

13. This Agreement shall inure to the benefit of and be binding upon the Company and the Underwriters, the officers and directors of the Company referred to herein, any controlling persons referred to herein and their respective successors and assigns. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any other person, firm or corporation any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. No purchaser of Shares from any Underwriter shall be deemed to be a successor or assign by reason merely of such purchase.

14. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given upon receipt thereof by the recipient if mailed or transmitted by any standard form of telecommunication. Notices to the Underwriters shall be given to the Representative, c/o Howe ▇▇▇▇▇▇ ▇▇▇▇▇▇ & ▇▇▇▇▇▇, Inc., ▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇ ▇▇▇▇▇ (fax no.: ▇▇▇-▇▇▇-▇▇▇▇); Attention: General Counsel, with a copy to ▇▇▇▇▇▇ & ▇▇▇▇ PC, ▇▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇, ▇▇▇▇▇ ▇▇▇, ▇▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇(▇▇▇ no.

(▇▇▇) ▇▇▇-▇▇▇▇); Attention: ▇▇▇▇▇ ▇▇▇▇▇▇.

15. This Agreement may be signed in counterparts, each of which shall be an original and all of which together shall constitute one and the same instrument.

16. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF ILLINOIS, WITHOUT REGARD TO SUCH STATE’S PRINCIPLES OF CONFLICTS OF LAWS.

17. The parties hereby submit to the jurisdiction of and venue in the state and federal courts located in the City of Chicago, Illinois in connection with any dispute related to this Agreement, any transaction contemplated hereby, or any other matter contemplated hereby.

18. The Company acknowledges and agrees that (i) the purchase and sale of the Shares pursuant to this Agreement, including the determination of the public offering price of the Shares and any related discounts and commissions, is an arm’s-length commercial transaction between the Company on the one hand, and the several Underwriters, on the other, (ii) in connection therewith and with the process leading to such transaction each Underwriter is acting solely as a principal and not the agent or fiduciary of the Company or its respective stockholders, creditors, employees or any other party, (iii) no Underwriter has assumed or will assume an advisory or fiduciary responsibility in favor of the Company with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Company on other matters) or any other obligation to the Company except the obligations expressly set forth in this Agreement, (iv) the Underwriters and their respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Company, and (v) the Underwriters have not provided any legal, accounting, regulatory, tax or financial advice with respect to the offering contemplated hereby and the Company has consulted its own legal, accounting, regulatory, tax and financial advisors to the extent it deemed appropriate. The Company agrees that it will not claim that the

Underwriters, or any of them, has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to the Company, in connection with such transaction or the process leading thereto.

19. Notwithstanding anything herein to the contrary, the Company is authorized to disclose to any persons the U.S. federal and state income tax treatment and tax structure of the potential transaction and all materials of any kind (including tax opinions and other tax analyses) provided to the Company relating to that treatment and structure, without the Underwriters imposing any limitation of any kind. However, any information relating to the tax treatment and tax structure shall remain confidential (and the foregoing sentence shall not apply) to the extent necessary to enable any person to comply with securities laws. For this purpose, “tax structure” is limited to any facts that may be relevant to that treatment.

20. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company and the Underwriters, or any of them, with respect to the subject matter hereof.

21. The Company and each of the Underwriters hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

(xiv) The documents incorporated by reference in the Pricing Disclosure Package and the Prospectus (other than the financial statements and supporting schedules included therein or omitted therefrom, as to which we express no opinion), when they were filed with the Commission comply as to form in all material respects with the requirements of the Securities Act or the Exchange Act, as applicable, and the rules and regulations of the Commission thereunder.

“Supervision and Regulation” in the Company’s Annual Report on Form 10-K filed on March 5, 2010, which is incorporated by reference into the Prospectus, and (ii) in the Registration Statement under Item 14 (Indemnification of Directors and Officers), insofar as they purport to describe provisions of the law, the Company’s articles of incorporation and by-laws and documents referred to therein are accurate in all material respects.

(xvi) To the knowledge of counsel, neither the Company nor the Bank is in violation of its charter or by-laws and no default by the Company or the Bank exists in the due performance or observance of any material obligation, agreement, covenant or condition contained in any contract, indenture, mortgage, loan agreement, note, lease or other agreement or instrument that is filed with or incorporated by reference as an exhibit to the Registration Statement or any Rule 462(b) Registration Statement (the “Covered Contracts”).

(xvii) No filing with, or authorization, approval, consent, license, order, registration, qualification or decree of, any court or governmental authority or agency, domestic or foreign (other than under the Securities Act and the Rules and Regulations, which have been made or obtained, or as may be required under the securities or blue sky laws of the various states, as to which we express no opinion) is necessary or required in connection with the due authorization, execution and delivery of the Underwriting Agreement or for the offering, issuance, sale or delivery of the Shares in accordance with the Underwriting Agreement.

(xix) The Company is not an “investment company” or an entity “controlled” by an “investment company,” as such terms are defined in the Investment Company Act.

(xx) To the knowledge of counsel, without independent investigation, neither the Company nor the Bank is a party to or subject to any order, decree, agreement, memorandum of understanding or similar arrangement with, or a commitment letter, supervisory letter or similar submission to, any governmental entity charged with the supervision or regulation of depository institutions or engaged in the insurance of deposits (including the FDIC) or the supervision or regulation of the Company or the Bank and neither the Company nor the Bank has been advised

by any such governmental entity that such governmental entity is contemplating issuing or requesting (or is considering the appropriateness of issuing or requesting) any such order, decree, agreement, memorandum of understanding, commitment letter, supervisory letter or similar submission.

(xxi) To the knowledge of counsel, without independent investigation, the Company and the Bank have obtained all material licenses, permits and other governmental authorizations required for the conduct of their respective businesses as described in the Registration Statement, the Pricing Disclosure Package, and the Prospectus, except where the failure to obtain such licenses, permits and other governmental authorizations would not have a Material Adverse Effect, and all such licenses, permits and other governmental authorizations are in full force and effect, except where the failure to be in full force and effect would not, individually or in the aggregate, have a Material Adverse Effect; to the knowledge of counsel, without independent investigation, neither the Company nor any of its Subsidiaries have received any communication from any governmental entity asserting that the Company or any of its subsidiaries is not in compliance with any statute, law, rule, regulation, decision, directive or order.

Counsel will also state that while such counsel has participated in conferences with officers and other representatives of the Company, the Underwriters, counsel to the Underwriters and representatives of the independent public accountants for the Company at which conferences the contents of the Registration Statement, the Pricing Prospectus, the Pricing Disclosure Package, the Prospectus and related matters were discussed. Given the limitations inherent in the role of outside counsel and the character of determinations involved in the preparation of such documents, counsel is not passing upon and does not assume responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement, or the Pricing Prospectus, the Pricing Disclosure Package, the Prospectus and have made no independent check or verification thereof (except as indicated in paragraphs (ii), (viii) and (xi) above). On the basis of the foregoing, no facts have come to counsel’s attention that lead them to believe that, (i) the Registration Statement, as of its effective date, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) the Pricing Disclosure Package, taken together as a whole, as of the Applicable Time and the Closing Date contained an untrue statement of a material fact or omitted to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading or (iii) the Prospectus, as of its date or as of the date of counsel’s opinion, contained an untrue statement of a material fact or omitted to state a material fact necessary to make the statement therein, in the light of the circumstances under which they were made, not misleading, except that in each case counsel need not express any opinion or belief with respect to the financial statements or other financial or statistical data contained or incorporated by reference in the Registration Statement, the Pricing Disclosure Package or the Prospectus.

In addition, counsel will confirm that, to the knowledge of counsel, there is not pending or threatened any action, suit, proceeding, inquiry or investigation, to which the Company or any Subsidiary is a party, or to which the property of the Company or any Subsidiary is subject, before or brought by any court or governmental agency or body, domestic or foreign, which if determined adversely against the Company or any of its Subsidiaries would reasonably be expected to result in a Material Adverse Effect, or which might reasonably be expected to

materially and adversely affect the properties or assets thereof or the consummation of the transactions contemplated in the Underwriting Agreement or the performance by the Company of its obligations thereunder.
