Section 6. Covenants.

     (a) Regulatory Approvals. The Company and the Investor will use commercially reasonable best efforts to obtain, as promptly as practicable, all governmental, quasi-governmental, court or regulatory approvals, consents or statements of non-objection necessary on its part to allow the Company to issue and the Investor to acquire the Preferred Shares and Conversion Shares it will or may acquire or control, as the case may be, or to own or control the Preferred Shares, the Conversion Shares or any other shares of Common Stock to be issued by the Company or owned or controlled by the Investor following the date hereof, including any approvals, consents or statements of non-objection required by any state or federal banking regulatory authority, including the Regulatory Approvals applicable to them. In performing its obligations under this Section 6(a), each of the Company and the Investor will cooperate with the other, provide each other to the extent reasonably practicable with advance notice of and an opportunity to comment to the non-confidential portions of all regulatory filings, applications and support materials, and will provide each other with advance notice of and an opportunity to

participate in any meetings (including telephonic conferences) with any regulatory authorities regarding any such approvals to the extent they do not involve such party’s confidential information. Without limiting the foregoing, unless otherwise waived by the Company, the Investor agrees, as and to the extent required by applicable law, that it will as promptly as practicable prepare, file and prosecute with the OTS a submission rebutting the presumption of control of the Company as provided in 12 CFR §574.4(e) and offer to enter into the Rebuttal of Control Agreement required by 12 CFR §574.100 as such agreement may be modified from time to time by the OTS (the “Form Agreement”), as may be amended or modified by the Investor and the OTS to reflect the business and structure of the Investor; provided, the Investor shall use its commercially reasonable best efforts to conform with the requirements of the Form Agreement. The Investor also agrees that it will take no action that would result in the Investor becoming a “savings and loan holding company” as that term is defined in the Home owners Loan Act and 12 CFR Part 574 and that, beginning on the date of filing the submission described in the immediately preceding sentence with the OTS, prior to the Closing, it will take no action that would cause it not to be able to fully comply with the terms of such Rebuttal of Control Agreement. The Company will cooperate with the Investor and the Company will use commercially reasonable best efforts in assisting the Investor in performing its obligations under this Section 6(a), including, if requested by the Investor, entering into a compliance agreement with the Investor designed to reduce the likelihood of transactions with Affiliates of the Investor that would be prohibited pursuant to the terms of any Rebuttal of Control Agreement entered into by the Investor and the OTS. The Company and the Investor shall, promptly upon receipt of each Regulatory Approval applicable to it, provide written notice to the other party of such receipt.

     (b) Cooperation. The Investor will, and will cause its Affiliates to, cooperate with the Company and use commercially reasonable efforts to take, or cause to be taken, all commercially reasonable actions in order to facilitate the successful consummation of the transactions contemplated hereby. The Company will, and will cause its Affiliates to (i) cooperate with the Investor and use commercially reasonable efforts to take, or cause to be taken, all commercially reasonable actions in order to facilitate the successful consummation of the transactions contemplated hereby, and (ii) assist the Investor in any appearances and proceedings before and consents, approvals, or waivers sought from any Governmental Entity with respect to the consummation of the transactions contemplated hereby.

     (c) Legends. (i) The Investor agrees that all certificates or other instruments representing the Preferred Shares and the Conversion Shares subject to this Agreement will bear a legend substantially to the following effect:

     (A) THE SECURITIES REPRESENTED BY THIS INSTRUMENT HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR SECURITIES LAWS OF ANY STATE AND MAY NOT BE TRANSFERRED, SOLD OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO A REGISTRATION STATEMENT RELATING THERETO IN EFFECT UNDER SUCH ACT AND APPLICABLE STATE SECURITIES LAWS OR PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER SUCH ACT OR SUCH LAWS.

     (B) THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A VOTING AGREEMENT AND TRANSFER AND OTHER RESTRICTIONS SET FORTH IN AN INVESTMENT AGREEMENT, DATED AS OF JUNE 7, 2008, COPIES OF WHICH ARE ON FILE WITH THE ISSUER.

     (ii) Upon request of the Investor, upon (x) receipt by the Company of an opinion of counsel reasonably satisfactory to the Company to the effect that such legend is no longer required under the Securities Act and applicable state laws, or (y) the Investor providing the Company with reasonable assurance that the securities can be sold, assigned or transferred pursuant to Rule 144, the Company will promptly cause clause (A) of the legend to be removed from any certificate for any Preferred Shares or Conversion Shares to be transferred by the Investor in accordance with the terms of this Agreement and clause (B) of the legend will be removed upon the expiration of such transfer and other restrictions set forth in this Agreement. The Investor acknowledges that neither the Preferred Shares nor the Conversion Shares have been registered under the Securities Act or under any state securities laws and the Investor agrees that it will not sell or otherwise dispose of any of the Preferred Shares or Conversion Shares, except in compliance with the registration requirements or exemption provisions of the Securities Act and any other applicable securities laws.

     (d) No Other Preferred. Until such time as all of the Preferred Shares have been converted into shares of Common Stock, the Company shall not, without the prior written consent of the Holders owning at least 51% of the then outstanding shares of Convertible Preferred Stock, create, authorize or designate any preferred stock of any class or series having any designations, preferences, relative, participating, optional or other rights ranking senior to or on parity with those of the Convertible Preferred Stock.

Section 9. Additional Covenants.

     (a) Standstill. The Investor and the Company agree that the one year period specified in the first sentence of Section 6 (Standstill) (the “Standstill”) of that certain Confidentiality Agreement by and between the Company and the Investor will expire on December 31, 2008, and, the Standstill will not apply to purchases by the Investor of Common Stock and any other securities or instruments convertible into or exchangeable for Common Stock to the extent such purchases result in the Investor having beneficial ownership (as determined in accordance with Rule 13d-3 under the Exchange Act) of less than 19.9% of the issued and outstanding shares of Common Stock (assuming for this purpose, full conversion of the Convertible Preferred Stock). In addition, the Standstill will automatically become inoperative and of no force or effect if (i) any Person or “group” (within the meaning of Section 13(d)(3) of the Exchange Act) shall have acquired or entered into a definitive agreement to acquire more than 20% of the equity securities of the Company or assets of the Company or its subsidiaries representing more than 20% of the consolidated earning power of the Company and its subsidiaries (an “Issuer Sale Transaction”), (ii) a third party makes a tender offer for more than 20% of the equity securities of the Company (a “Third-Party Tender Offer”) and the Company files a Schedule 14D-9 with respect to such

offer that does not recommend that the Company’s stockholders reject such offer, (iii) the Company effects a transaction, or series of related transactions, involving the issuance of securities representing 15% or more (assuming the conversion of all convertible securities issued in such transaction or series of related transactions) of the pro-forma outstanding equity securities of the Company, unless the Investor is offered the opportunity to participate in, or does in fact participate in, such transaction and, such opportunity if accepted by the Investor would result in the Investor beneficially owning equity securities of the Company representing at least the same percentage of the outstanding equity securities of the Company that it beneficially owned immediately prior to such transaction, (iv) any Person or “group” (within the meaning of Section 13(d)(3) of the Exchange Act) commences a solicitation of proxies or written consents to elect to the Board of Directors any individuals or slate of individuals in a contest with any individuals or slate of individuals whose nomination has been approved by the Nominating and Corporate Governance Committee (or its equivalent) of the Board of Directors, or (v) termination of the Rights Agreement or an increase in the triggering threshold thereunder to a percentage in excess of 20%, in which case the percentage limitation in the first sentence of this Section 9(a) will be increased to 1/10% less than such revised triggering threshold. Notwithstanding the foregoing or any other provision of this Agreement, the Investor will not be required to (x) vote any shares or other voting equity securities of the Company that it beneficially owns in favor of, or provide a consent or proxy approving, any Issuer Sale Transaction, or (y) tender any equity securities of the Company in response to a Third-Party Tender Offer.

     (b) Reservation for Issuance. The Company will at all times reserve and keep available, out of its authorized but unissued Common Stock, solely for the purpose of effecting the conversion of the Preferred Shares, the full number of Conversion Shares. Additionally, the Company will at all times prior to the Closing reserve and keep available, out of its authorized but unissued shares of preferred stock, solely for the purpose of issuing the Preferred Shares at the Closing, a sufficient number of shares of preferred stock to allow the issuance of all shares of Preferred Stock necessary to be issued to the Holders.

     (c) Exchange Listing. The Company will promptly use its reasonable best efforts to cause the Conversion Shares to be approved for listing on the NYSE, subject to official notice of issuance and upon receipt of the Stockholder Approval.

     (d) Stockholder Meeting. The Company will call a special meeting of its stockholders, as promptly as practicable following the Closing Date to approve the conversion of the Preferred Shares into Common Stock for purposes of complying with the requirements of the NYSE, and use commercially reasonable efforts to take any other action necessary to effect such conversion. The Board of Directors will recommend to the Company’s stockholders that such stockholders vote in favor of the proposals required by this Section 9(d). In connection with such meeting, the Company will promptly prepare and file with the Commission a preliminary proxy statement, will use its reasonable best efforts to respond to any comments of the Commission or its staff and to cause a definitive proxy statement related to such stockholders’ meeting to be mailed to the Company’s stockholders not more than five Business Days after clearance thereof by the Commission staff, and will use its reasonable best efforts to solicit proxies for such stockholder approval. In the event that the approvals necessary to permit the Preferred Shares to be converted into Common Stock are not obtained at such special

stockholders meeting, the Company will include a proposal to approve (and the Board of Directors, to the extent it is consistent with its fiduciary duties, will recommend approval of) such issuance at a meeting of its stockholders no less than once in each subsequent six-month period beginning on January 1, 2009 and ending on the earlier of (i) the date such approval is obtained or made, or (ii) May 31, 2012, and if Stockholder Approval has not been obtained by May 31, 2012, the Company will cause all Preferred Shares to be listed on each securities exchange on which similar securities issued by the Company are then listed or, if no similar securities issued by the Company are then listed on any securities exchange, use its reasonable best efforts to cause all such Preferred Shares to be listed on the NYSE or the NASDAQ stock market, as determined by the Company.

     (e) Voting Agreement. As a material inducement to the Company’s entering into this Agreement and issuing and selling the Preferred Shares to the Investor, the Investor irrevocably covenants and agrees to vote and to execute written consents, and to cause its Affiliates to vote and execute written consents, at any meeting of the stockholders of the Company or in any action taken by the stockholders without a meeting, with respect to all Voting Securities over which the Investor or any of its Affiliates has voting power (i) in favor of the Stockholder Approval, and (ii) against any action, agreement or proposal that would result in the Stockholder Approval not being obtained acting with the intent of hindering, delaying, frustrating, impairing or making futile or less likely the Stockholder Approval. Upon the execution of this Agreement, the Investor hereby revokes any and all other proxies and voting agreements given by the Investor with respect to its Voting Securities and the Investor will cause its Affiliates to revoke any and all other proxies and voting agreements given by such Affiliate with respect to its Voting Securities. As of the date hereof, the Investor has voting power with respect to all shares of Common Stock set forth opposite the Investor’s name on Schedule 1. The agreements and restrictions set forth in this Section 9(e) will be binding on any transferee of the Preferred Shares, and the Investor agrees that it will, as a condition to the transfer of the Preferred Shares require that any transferee of such Preferred Shares take such Preferred Shares subject to the terms of this Section 9(e). This agreement to vote is irrevocable and coupled with an interest and will expire upon termination of this Agreement, upon the receipt of the Stockholder Approval, or the expiration of any period beyond which agreements to vote are not enforceable under applicable law, whichever comes first.

     (f) Reports Under the Exchange Act. With a view to making available to the Investor the benefits of Rule 144, the Company agrees to (i) make and keep public information available, as those terms are understood and defined in Rule 144, (ii) file with the Commission in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act so long as the Company remains subject to such requirements and the filing of such reports and other documents is required for the applicable provisions of Rule 144; and (iii) furnish to the Investor so long as the Investor owns Registrable Securities, promptly upon request (A) a written statement by the Company, if true, that it has complied with the reporting requirements of Rule 144, the Securities Act and the Exchange Act, (B) a copy of the most recent annual or quarterly report of the Company and such other reports and documents so filed by the Company, and (C) such other information as may be reasonably requested to permit the Investors to sell such securities pursuant to Rule 144 without registration.

     (g) Investment Agreements. Without the prior consent of the Investor, which consent will not be unreasonably delayed, the Company will not amend, modify or supplement any Investment Agreement.

     (h) Disclosure of Material Non-Public Information. The next Business Day following the execution and delivery of this Agreement, the Company agrees to file a Current Report on Form 8-K regarding the transactions contemplated by this Agreement and the Investment Agreements. The Company hereby represents and warrants to the Investor that, upon the filing of such Form 8-K, the Company will have disclosed in the Company SEC Documents all material non-public information that the Company had previously provided to the Investor.

Section 10. Registration Rights.

     (a) Required Registration. Any Holder or Holders owning at least 15% of the Registrable Securities then outstanding, will have the right, by written notice (the “Registration Notice”) to the Company, to require the Company to use reasonable efforts to register (the “Required Registration”) under the Securities Act Registrable Securities with an anticipated aggregate offering price, net of underwriting discounts and commissions, of at least $50,000,000; provided that the Company will be obligated to register such Registrable Securities pursuant to this Section 10(a) on only two occasions, as long as each Holder will have been given notice of and the opportunity to participate in each such registration. The Company will be entitled to sell shares of Voting Securities (to be newly issued or from shares held in treasury) pursuant to such Required Registration and any Holder will be entitled to sell any shares of Voting Securities held by such Holder which are not Registrable Securities (the “Additional Securities”); provided, that if the managing underwriter will advise the Company in writing that, in its opinion, the number of securities requested and otherwise proposed to be included in such offering exceeds the number that can be sold without adversely affecting the marketability of the offering, the Company will include in such registration to the extent of the number which the Company is so advised can be sold in such offering, first, the Registrable Securities the requesting Holders propose to sell in such registration; second, the Additional Securities that any Holders propose to sell in such registration; and third the Registrable Securities of the Company that the Company proposes to include in such registration, which, in the opinion of such managing underwriter, can be sold without having the adverse effect referred to above. Upon receipt of such Registration Notice, the Company will, as promptly as practicable, prepare and file with the SEC and use its reasonable efforts to cause to become effective promptly, a registration statement under the Securities Act registering the Registrable Securities specified in the Registration Notice; provided, however, that the Company will be entitled to defer any such filing (i) which would result in an effective registration statement within six months of an underwritten offering by the Company of its equity securities for its own account or (ii) for a period of up to 180 days upon a determination by the Board of Directors that the filing of a registration statement at such time would be detrimental to the Company due to the pendency of a material acquisition or financing or for other reasonable cause.

     (b) Form S-3 Registration. If the Company receives from the Investor a written request that the Company effect a registration on Form S-3, the Company will (i) promptly give written notice of the proposed registration to all other Holders; (ii) as soon as practicable, file such registration for the sale and distribution of all or such portion of the Investor’s Registrable

Securities as are specified in such request, together with all or such portion of the Registrable Securities of any other Holders joining in such request as are specified in a written request given within 15 days after receipt of such written notice from the Company; provided, however, that the Company will not be obligated to effect any such registration pursuant to this Section 10(b): (A) if Form S-3 is not then available for such offering by the Holders; (B) if the Holders, together with the holders of any other securities of the Company entitled to inclusion in such registration, propose to sell Registrable Securities and such other securities (if any) at an aggregate price to the public (net of any underwriters’ discounts or commissions) of less than $5,000,000; (C) if the Board of Directors determines that the filing of a registration statement at such time would be detrimental to the Company due to the pendency of a material acquisition or financing or for other reasonable cause, in which event the Company will have the right to defer the filing of the Form S-3 for a period of not more than 180 days after receipt of the request of the Holders under this Section 10(b); provided, however, that the Company will not utilize this deferral right more than once in any 12 month period and provided further that the Company will not register any securities for the account of itself or any other equity holder during such 180 day period (other than a registration relating solely to the sale of securities to bona fide employees of the Company pursuant to an equity incentive plan, equity purchase or similar plan); (D) if the Company has, within the 12 month period preceding the date of such request, already effected two registrations on Form S-3 for the Holders pursuant to this Section 10(b); or (E) in any particular jurisdiction in which the Company would be required to qualify to do business or to execute a general consent to service of process in effecting such registration, qualification or compliance. Subject to the foregoing, the Company will file a registration statement on Form S-3 covering the Registrable Securities so requested to be registered as soon as practicable after receipt of the requests of the Holders. If the Investor intends to distribute the Registrable Securities covered by its request for registration by means of an underwriting, it will so advise the Company as part of their request made pursuant to this Section 2.10(b) and the Company will include such information in the written notice referred to in clause (i) above.

     (c) Incidental Registration Rights. In addition to the provisions contained in Sections 10(a) and 10(b), if the Company will at any time seek to register under the Securities Act for sale to the public in an underwritten offering any of its equity securities (other than a registration on Form S-4 or Form S-8, or any successor or other forms promulgated for similar purposes) and if the form of registration statement proposed to be used may be used for the registration of Registrable Securities, on each such occasion it will promptly furnish the Investor with prior written notice thereof. At the written request of the Investor, given (i) at a time when the Investor beneficially owns 5% or more of the outstanding Voting Securities and (ii) within five days after the receipt of such notice, to register any of the Investor’s Registrable Securities, the Company will cause such Registrable Securities, for which registration will have been requested, to be included in such registration statement in an amount so as to permit the sale or other disposition by the Investor as part of such underwritten public offering of such Registrable Securities as are registered, provided, that if the managing underwriter will advise the Company in writing that, in its opinion, the number of securities requested and otherwise proposed to be included in such offering exceeds the number that can be sold without adversely affecting the marketability of the offering, the Company will include in such registration to the extent of the number which the Company is so advised can be sold in such offering, first, the securities the Company proposes to sell in such registration and second, the Registrable Securities of the Investor that the Investor has requested to be included in such registration, which, in the opinion

of such managing underwriter, can be sold without having the adverse effect referred to above. If a Required Registration is an underwritten offering and the managing underwriters advise the Company in writing that in their opinion the number of Registrable Securities and, if permitted hereunder, other securities requested to be included in such offering exceeds the number of Registrable Securities and other securities, if any, which can be sold in an orderly manner in such offering within a price range acceptable to the holders of Registrable Securities initially requesting such Required Registration, without adversely affecting the marketability of the offering, the Company will include in such registration prior to the inclusion of any securities that are not Registrable Securities, the number of Registrable Securities requested to be included by the holders of Registrable Securities pro rata among the respective holders thereof on the basis of the number of Registrable Securities owned by each such holder.

     (d) Expenses. All expenses incurred by the Company in complying with this Section 10, including all registration and filing fees, printing expenses, fees and disbursements of counsel (including one counsel for all of the Holders) and independent public accountants for the Company, fees of the Financial Industry Regulatory Authority, listing or quotation fees, and fees of transfer agents and registrars, will be borne in full by the Company. The Investor will be responsible for all underwriting commissions, transfer taxes, discounts and fees with respect to Registrable Securities and the fees and expenses of accountants for the Investor and any counsel hired by the Investor in addition to the one counsel of the Holders paid for by the Company.

     (e) Listing. The Company will cause all Registrable Securities registered as provided in this Section 10 to be listed on each securities exchange on which similar securities issued by the Company are then listed or, if no similar securities issued by the Company are then listed on any securities exchange, use its reasonable best efforts to cause all such Registrable Securities to be listed on the NYSE or the NASDAQ stock market, as determined by the Company.

     (f) Indemnification. The Company will enter into customary and reasonable indemnification and contribution agreements with any underwriter and the Investor in the event of an underwritten offering.

Section 11. Survival. The representations and warranties of the Company contained in this Agreement or in any certificate delivered hereunder will terminate on and as of the Closing, except for the representations and warranties set forth in Section 3(a) (organization and authority) and Section 3(b) (authorization), which will survive indefinitely.
