Company is duly qualified as a foreign corporation to transact business and is in good standing in each other jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except where the failure so to qualify or to be in good standing would not result in a Material Adverse Effect.

There are, as of the date hereof, no outstanding options, rights, warrants or other agreements or instruments obligating Company to issue, deliver or sell, or cause to be issued, delivered or sold, additional shares of the capital

9 stock of Company or obligating Company to grant, extend or enter into any such agreement or commitment to any Person other than Company except (i) as described in Company’s SEC Reports or (ii) pursuant to employment arrangements, agreements or understanding or Company’s equity incentive plans approved or adopted by Company’s Board of Directors. 3.

Subordinated Notes. The Subordinated Notes have been duly authorized by Company and when executed by Company and issued, delivered to and paid for by the Purchasers in accordance with the terms of the Agreement, will have been duly executed, authenticated, issued and delivered and will constitute legal, valid and binding obligations of Company, and enforceable in accordance with their terms, except as enforcement thereof may be limited by bankruptcy, insolvency, reorganization, moratorium or other similar laws relating to or affecting creditors’ rights generally or by general equitable principles. 4. No Defaults or Restrictions. Neither the execution and delivery of the Transaction Documents nor compliance with their respective terms and conditions will (whether with or without the giving of notice or lapse of time or both) (i) violate, conflict with or result in a breach of, or constitute a default under: (1) the Articles of Incorporation or Bylaws of Company; (2) any of the terms, obligations, covenants, conditions or provisions of any corporate restriction or of any contract, agreement, indenture, mortgage, deed of trust, pledge, bank loan or credit agreement, or any other agreement or instrument to which Company or Bank, as applicable, is now a party or by which it or any of its properties may be bound or affected; (3) any judgment, order, writ, injunction, decree or demand of any court, arbitrator, grand jury, or Governmental Agency

10 applicable to Company or Bank; or (4) any statute, rule or regulation applicable to Company, except, in the case of items (2), (3) or (4), for such violations, conflicts, breaches or defaults that would not reasonably be expected to have, singularly or in the aggregate, a Material Adverse Effect on Company and its Subsidiaries, taken as a whole, or (ii) result in the creation or imposition of any lien, charge or encumbrance of any nature whatsoever upon any property or asset of Company or any subsidiary. Neither Company nor Bank is in material default in the performance, observance or fulfillment of any of the terms, obligations, covenants, conditions or provisions contained in any Material Contract creating, evidencing or securing Indebtedness of any kind or pursuant to which any such Indebtedness is issued, or any other Material Contract. 5. Governmental Consent. No governmental orders, permissions, consents, approvals or authorizations are required to be obtained by Company that have not been obtained, and no registrations or declarations are required to be filed by Company that have not been filed in connection with, or, in contemplation of, the execution and delivery of, and performance under, the Transaction Documents, except for applicable requirements, if any, of the Securities Act, the Exchange Act or state securities laws or “blue sky” laws of the various states and any applicable federal or state banking laws and regulations. C. Possession of Licenses and Permits. Company and its Subsidiaries possess such permits, licenses, approvals, consents and other authorizations (collectively, “Governmental Licenses”) issued by the appropriate Governmental Agencies necessary to conduct the business now operated by it except where the failure to possess such Governmental Licenses would not, singularly or in the aggregate, have a Material Adverse Effect on Company or such applicable Subsidiary; Company and each Subsidiary of Company is in compliance with the terms and conditions of all such Governmental Licenses, except where the failure so to comply would not, singly or in the aggregate, have a Material Adverse Effect on Company or such applicable Subsidiary of Company; all of the Governmental Licenses are valid and in full force and effect, except where the invalidity of such Governmental Licenses or the failure of such Governmental Licenses to be in full force and effect would not have a Material Adverse Effect on Company or such applicable Subsidiary of Company; and neither Company nor any Subsidiary of Company has received any notice of proceedings relating to the revocation or modification of any such Governmental Licenses.

Absence of Default. Since the date of the latest audited financial statements included in Company’s SEC Reports, no event has occurred which either of itself or with the lapse of time or the giving of notice or both, would give any creditor of Company the right to accelerate the maturity of any material Indebtedness of Company. Company is not in default under any other Lease, agreement or instrument, or any law, rule, regulation, order, writ, injunction, decree, determination or award, non-compliance with which could reasonably be expected to result in a Material Adverse Effect on Company. 3.

12 with, borrowing from or other obligations to the Federal Home Loan Bank, inter- bank credit facilities, reverse repurchase agreements or any transaction by Bank acting in a fiduciary capacity, (ii) statutory liens for amounts not yet delinquent or which are being contested in good faith and (iii) such as do not, singly or in the aggregate, materially affect the value of such property and do not materially interfere with the use made and proposed to be made of such property by Company or any of its Subsidiaries. Company and each of its Subsidiaries, as lessee, has the right under valid and existing leases of real and personal properties that are material to Company or such Subsidiary, as applicable, in the conduct of its business to occupy or use all such properties as presently occupied and used by it.

Regulatory Enforcement Actions. Company, Bank and its other Subsidiaries are in compliance with all laws administered by and regulations of any Governmental Agency applicable to it or to them, except where the failure to so comply would have a Material Adverse Effect.

13 3. Pending Litigation.

No Misstatement. The information furnished by Company to Purchasers in the investor presentation utilized by Company in connection with the offering and sale of the Subordinated Notes (including statements made by members of Company management with respect to such investor presentation), along with Company SEC Reports and other information disclosed publicly by Company, does not contain any untrue statement of a material fact, or omit to state a material fact necessary to make the statements contained therein, in light of the circumstances under which they were made, not misleading.

J. Disclosure Controls and Procedures. Company and its Subsidiaries maintain an effective system of disclosure controls and procedures (as defined in Rule 13a-15 and Rule 15d-15 of the Exchange Act), that (i) are designed to ensure that information required to be disclosed by Company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that material information relating to Company and its Subsidiaries is made known to Company’s principal executive officer and principal financial officer by others within Company and its Subsidiaries to allow timely decisions regarding disclosure, and (ii) are effective in all material respects to perform the functions for which they were established. As of the date hereof, Company has no knowledge that would reasonably cause it to believe that the evaluation to be conducted of the effectiveness of Company’s disclosure controls and procedures for the most recently ended fiscal quarter period will result in a finding that such disclosure controls and procedures are ineffective for such quarter ended. Based on the evaluation of Company’s and each Subsidiary’s disclosure controls and procedures described above, Company is not aware of (1) any significant deficiency in the design or operation of internal controls which could adversely affect Company’s ability to record, process, summarize and report financial data or any material weaknesses in internal controls or (2)

15 any fraud, whether or not material, that involves management or other employees who have a significant role in Company’s internal controls. Since the most recent evaluation of Company’s disclosure controls and procedures described above, there have been no significant changes in internal controls or in other factors that could significantly affect internal controls. K. No Registration. No person has the right to require Company or any of its Subsidiaries to register any securities for sale under the Securities Act by reason of the issuance and sale of the Subordinated Notes to be sold by Company hereunder. L. Allowance for Loan Losses. The allowance for loan losses shown in the financial statements of Company has been established in a manner consistent with past practices and in accordance with applicable regulatory guidelines and, to the best of Company’s knowledge, is adequate in all respects to provide for losses, net of recoveries relating to loans previously charged off, on loans and leases outstanding as of the date of such statements or reports. M. Representations and Warranties Generally. The representations and warranties of Company set forth in this Agreement are true and correct as of the date hereof and will be true and correct as of the Closing Date and as otherwise specifically provided herein. Any certificate signed by an officer of Company and delivered to the Purchasers or to counsel for Purchasers shall be deemed to be a representation and warranty by Company to the Purchasers as to the matters set forth therein. V. GENERAL COVENANTS, CONDITIONS AND AGREEMENTS. Company hereby further covenants and agrees with each Purchaser as follows: A. Compliance with Transaction Documents. Company shall comply with, observe and timely perform each and every one of the covenants, agreements and obligations under the Transaction Documents. B. Compliance with Laws. 1. Generally. Company shall comply and cause Bank and each other Subsidiary to comply with all applicable statutes, rules, regulations, orders and restrictions in respect of the conduct of its business and the ownership of its properties, except, in each case, where such noncompliance would not reasonably be expected to have a Material Adverse Effect on Company. 2. Regulated Activities. Company shall not itself, nor shall it cause, permit or allow Bank or any other Subsidiary (i) engage in any business or activity not permitted by all applicable laws and regulations, except where such business or activity would not reasonably be expected to have a Material Adverse Effect on Company, Bank and/or such Subsidiary or (ii) make any loan or advance secured by the capital stock of another bank or depository institution, or acquire the

16 capital stock, assets or obligations of or any interest in another bank or depository institution, in each case other than in accordance with applicable laws and regulations and safe and sound banking practices. 3. Taxes. Company shall and shall cause Bank and any other Subsidiary to promptly pay and discharge all material taxes, assessments and other governmental charges imposed upon Company, Bank or any other Subsidiary or upon the income, profits, or property of Company or any Subsidiary and all claims for labor, material or supplies which, if unpaid, might by law become a lien or charge upon the property of Company, Bank or any other Subsidiary. Notwithstanding the foregoing, none of Company, Bank or any other Subsidiary shall be required to pay any such tax, assessment, charge or claim, so long as the validity thereof shall be contested in good faith by appropriate proceedings, and appropriate reserves therefor shall be maintained on the books of Company, Bank and such other Subsidiary. 4. Dividends, Payments, and Guarantees During Event of Default. During the continuance of an Event of Default (as defined under the Subordinated Notes) and except as required by any federal or state Governmental Agency, Company agrees not to (a) declare or pay any dividends on, or redeem, purchase, acquire or make a liquidation payment with respect to, any of its capital stock; (b) make any payment of principal of, or interest or premium, if any, on, or repay, repurchase or redeem any of Company’s debt that ranks equal with or junior to the Subordinated Notes; or (c) make any payments under any guarantee that ranks equal with or junior to the Subordinated Notes, other than (i) any dividends or distributions in shares of, or options, warrants or rights to subscribe for or purchase shares of, any class of Company’s common stock; (ii) any declaration of a dividend in connection with the implementation of a shareholders’ rights plan, or the issuance of stock under any such plan in the future, or the redemption or repurchase of any such rights pursuant thereto; (iii) as a result of a reclassification of Company’s capital stock or the exchange or conversion of one class or series of Company’s capital stock for another class or series of Company’s capital stock; (iv) the purchase of fractional interests in shares of Company’s capital stock pursuant to the conversion or exchange provisions of such capital stock or the security being converted or exchanged; or (v) purchases of any class of Company’s common stock related to the issuance of common stock or rights under any benefit plans for Company’s directors, officers or employees or any of Company’s dividend reinvestment plans. C. Absence of Control. It is the intent of the parties to this Agreement that in no event shall Purchasers, by reason of any of the Transaction Documents, be deemed to control, directly or indirectly, Company, and Purchasers shall not exercise, or be deemed to exercise, directly or indirectly, a controlling influence over the management or policies of Company.

17 D. Secondary Market Transactions. Each Purchaser shall have the right at any time and from time to time to securitize its Subordinated Notes or any portion thereof in a single asset securitization or a pooled loan securitization of rated single or multi-class securities secured by or evidencing ownership interests in the Subordinated Notes (each such securitization is referred to herein as a “Secondary Market Transaction”). In connection with any such Secondary Market Transaction, Company shall, at Company’s expense, cooperate with Purchasers and otherwise reasonably assist Purchasers in satisfying the market standards to which Purchasers customarily adhere or which may be reasonably required in the marketplace or by applicable rating agencies in connection with any such Secondary Market Transaction. Subject to any written confidentiality obligation, all information regarding Company may be furnished, without liability except in the case of gross negligence or willful misconduct, to any Purchaser and to any Person reasonably deemed necessary by Purchaser in connection with participation in such Secondary Market Transaction. All documents, financial statements, appraisals and other data relevant to Company or the Subordinated Notes may be retained by any such Person. E. Bloomberg.

No failure to exercise or delay in exercising, by a Purchaser or any holder of the Subordinated Notes, of any right, power or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or privilege preclude any other or further exercise thereof, or the exercise of any other right or remedy provided by law. The rights and remedies provided in this Agreement are cumulative and not exclusive of any right or remedy provided by law or equity.

Failure on the part of the Purchasers to complain of any acts or failure to act or to declare an Event of Default, irrespective of how long such failure continues, shall not constitute a waiver by the Purchasers of their rights hereunder or impair any rights, powers or remedies on account of any breach or default by Company. D. Severability. Any provision of this Agreement which is unenforceable or invalid or contrary to law, or the inclusion of which would adversely affect the validity, legality or enforcement of this Agreement, shall be of no effect and, in such case, all the remaining terms and provisions of this Agreement shall subsist and be fully effective according to the tenor of this Agreement the same as though any such invalid portion had never been included herein. Notwithstanding any of the foregoing to the contrary, if any provisions of this Agreement or the application thereof are held invalid or unenforceable only as to particular persons or situations, the remainder of this Agreement, and the application of such provision to persons or situations other than those to which it shall have been held invalid or unenforceable, shall not be affected thereby, but shall continue valid and enforceable to the fullest extent permitted by law.

In the event that any signature is delivered by facsimile transmission, or by e-mail delivery of a “.pdf” format data file, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile signature page were an original thereof. N. Knowledge; Discretion. All references herein to Purchaser’s or Company’s knowledge shall be deemed to mean the knowledge of such party based on the actual knowledge of such party’s Chief Executive Officer and Chief Financial Officer or such other persons holding equivalent offices. Unless specified to the contrary herein, all references herein to an exercise of discretion or judgment by a Purchaser, to the making of a determination or designation by a Purchaser, to the application of a Purchaser’s discretion or opinion, to the granting or withholding of a Purchaser’s consent or approval, to the consideration of whether a matter or thing is satisfactory or acceptable to a Purchaser, or otherwise involving the decision making of a Purchaser, shall be deemed to mean that such Purchaser shall decide using the reasonable discretion or judgment of a prudent lender.
