          (a) As of the Effective Time, the Articles of Association and Bylaws of the Resulting Bank shall be identical to the Articles of Association and Bylaws of SBB as in effect immediately prior to the Effective Time except that the Articles of Association shall not include any designated series of Resulting Bank Preferred Stock (i.e. there shall be no series of preferred stock similar to the SBB Series A Preferred).

          (b) As of the Effective Time, the Board of Directors of SBB shall become the Board of Directors of the Resulting Bank, provided, however, that at the request of NMB prior to the Closing, one or more directors shall resign effective as of the Closing to be replaced by persons designated by NMB.

        2.5  Conversion of Newco Shares.  At the Effective Time, the outstanding shares of the Common Stock, par value $.001 per share, of Newco shall be converted into 1,000 shares of Resulting Bank Common Stock.

        2.6  Conversion of SBB Common Stock.  At the Effective Time, all outstanding shares of SBB Common Stock, other than Dissenting SBB Shares, shall be converted into the right to receive an aggregate of (the "Consolidation Consideration"): (a) (i) $29,112,793.32 less (ii) the Out-of-Pocket Costs plus (iii) the SBB Third Quarter Earnings if the Closing does not occur on or prior to November 15, 2001 and there is no SBB Delay, multiplied by (b) a fraction, the numerator of which shall be the number of outstanding shares of SBB Common Stock minus the number of Dissenting SBB Shares and the denominator of which shall be the number of outstanding shares of SBB Common Stock.

    2.7  Dissenting SBB Shares.  The holders of Dissenting SBB Shares shall be entitled to the rights of dissenting shareholders under 12 USC § 215. If there are any Dissenting SBB Shareholders, the Board of Directors of SBB and/or the Resulting Bank agrees to appoint the person designated by NMB to the committee required to be appointed pursuant to 12 USC § 215(c) to appraise the value of the Dissenting SBB Shares.

    2.8  Closing Payment  

          (a)  Paying Agent.  Prior to the Effective Time, SBB and NMB shall enter into the Paying Agent Agreement with the Paying Agent.

          (b)  Payment Procedure.  At the Effective Time, NMB shall deliver the Consolidation Consideration to the Paying Agent. The Paying Agent shall mail, as soon as practicable after the Closing, but within five Business Days, to each Non-Dissenting Shareholder: (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the certificates evidencing the shares of SBB Common Stock, shall pass, only upon delivery of the certificates to the Paying Agent and shall be in a form and have such other provisions as NMB may reasonably specify) and (ii) instructions for use in effecting the surrender of the certificates in exchange for the Closing Payment. Upon surrender of a certificate for cancellation to the Paying Agent together with such letter of transmittal, duly executed, and such other documents as may reasonably be required by the Paying Agent, the holder of such certificate shall be entitled to receive in exchange therefor such holder's pro rata share of the Closing Payment, and the certificate so surrendered shall forthwith be canceled. In the event of a transfer of ownership of the SBB Common Stock which is not registered in the transfer records of SBB, payment may be made to a person other than the person in whose name the Certificate so surrendered is registered, if such certificate shall be properly endorsed or otherwise be in proper form for transfer and the person requesting such payment shall pay any transfer or other taxes required by reason of the payment to a person other than the registered holder of such certificate or establish to the satisfaction of NMB that such tax has been paid or is not applicable. From and after the Effective Time, each share of SBB Common Stock shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the holder's pro rata share of the Consolidation Consideration (or, with respect to Dissenting SBB Shares, the rights under 12 USC § 215). No interest will be paid or will accrue on the Closing Payment.

7


        2.9  Failure to Surrender Certificates; No Liability.  Six months following the Closing Date, the Paying Agent shall return to NMB all Consolidation Consideration relating to shares of SBB Common Stock which have not been surrendered to the Paying Agent and the Paying Agent's duties shall terminate. Thereafter, each Non-Dissenting Shareholder may surrender the certificate evidencing its shares to NMB and (subject to applicable abandoned property, escheat and similar laws) receive in exchange therefor its pro rata share of the Consolidation Consideration (without interest thereon). None of NMB, Newco, SBB, the Resulting Bank or the Paying Agent shall be liable to any person in respect of any cash delivered to a public official pursuant to any applicable abandoned property, escheat or similar law.

        2.10  Withholding Taxes.  The right of any person to receive any payment or consideration pursuant to this Agreement and the transactions contemplated herein shall be subject to any applicable requirements with respect to the withholding of Taxes.

        2.11  Lost, Stolen or Destroyed Certificates.  In the event any certificates evidencing shares of SBB Common Stock shall have been lost, stolen or destroyed, the Paying Agent shall pay to the holder his or her pro rata share of the Consolidation Consideration required pursuant to Section 2.6, upon the making of an affidavit of that fact by the holder thereof with such assurances as the Paying Agent, in its discretion and as a condition precedent to the payment of the share of the Consolidation Consideration, may reasonably require of the holder of such lost, stolen or destroyed certificates, including the posting of a bond or indemnity.

        2.12  Supplementary Action.  If at any time after the Effective Time, any further assignments or assurances in law or any other things are necessary or desirable to vest or to perfect or confirm of record in the Resulting Bank the title to any property or rights of either Newco or SBB, or otherwise to carry out the provisions of this Agreement, the officers and directors of the Resulting Bank are hereby authorized and empowered, in the name of and on behalf of Newco and SBB, to execute and deliver any and all things necessary or proper to vest or to perfect or confirm title to such property or rights in the Resulting Bank and otherwise to carry out the purposes and provisions of this Agreement.

20


      Proposal, the material terms and conditions of such request, Acquisition Proposal or inquiry, and the identity of the person making any such Acquisition Proposal or inquiry. SBB will keep NMB fully informed of the status and details of any such request, Acquisition Proposal or inquiry.

Subject to the provisions of Section 5.4(c): (i) SBB will, through its Board of Directors, recommend to the SBB Shareholders that SBB Shareholder Approval be given; (ii) the proxy statement and other soliciting materials furnished by the SBB Board of Directors to the SBB Shareholder in connection with the Shareholders Meeting (the "Proxy Materials") shall include a statement to the effect that SBB's Board of Directors recommends that SBB Shareholder Approval be given at the Shareholders Meeting; and (iii) neither SBB's Board of Directors nor any committee thereof shall withdraw, amend or modify, or propose or resolve to withdraw, amend or modify in a manner adverse to NMB, the recommendation of SBB's Board of Directors that SBB Shareholder Approval be given at the Shareholders Meeting. Without limiting the generality of the foregoing, SBB agrees that its obligations pursuant to the first sentence of this Section 5.4(a) shall not be affected by (A) the commencement, public proposal, public disclosure or communication to SBB of any Acquisition Proposal (including a Superior Proposal) or (B) the withdrawal or modification by SBB's Board of Directors of its recommendation of this Agreement, the Consolidation or SBB Shareholder Approval.

          (b) The Proxy Materials shall not contain any misstatement of material fact or omit to state any material fact necessary to make the statements made therein, in light of the circumstances under which they were made, not misleading. If at any time prior to the Shareholders Meeting there shall occur any event that should be set forth in an amendment or supplement to the Proxy Materials, SBB will promptly prepare and mail to the SBB Shareholders such an amendment or supplement. SBB shall provide NMB with copies of any Materials, or any amendment or supplement thereto, at least five Business Days (three Business Days for an amendment or supplement) prior to mailing or delivering such Materials to the SBB Shareholders and will not mail or send any Proxy Materials, or any amendment or supplement thereto, to which NMB reasonably objects.

          (c) Nothing in this Agreement shall prevent SBB's Board of Directors from withholding, withdrawing, amending or modifying its recommendation in favor of the Consolidation prior to receipt of Shareholder Approval if (i) a Superior Proposal is made to SBB and is not withdrawn, (ii) SBB shall have provided written notice to NMB (a "Notice of Superior Proposal") advising NMB that SBB has received a Superior Proposal, specifying all of the material terms and conditions of such Superior Proposal and identifying the Person making such Superior Proposal, (iii) NMB shall not have made, within five Business Days of NMB's receipt of the Notice of Superior Proposal, an offer that SBB's Board by a majority vote determines in its good faith judgment, based upon the written advice of its financial adviser, to be at least as favorable to the SBB Shareholders as such Superior Proposal (it being agreed that SBB's Board of Directors shall convene a meeting to consider any such offer by NMB promptly following the receipt thereof), (iv) SBB's Board of Directors concludes in good faith, based on the written advice of its outside counsel, that, in light of such Superior Proposal, the withholding, withdrawal, amendment or modification of such recommendation is required in order for SBB's Board of Directors to comply with its fiduciary obligations to SBB's shareholders under applicable law and (v) SBB shall not have violated any of the restrictions

21


      set forth in Section 5.3 or this Section 5.4. SBB shall provide NMB with at least three Business Days prior notice (or such lesser prior notice as provided to the members of SBB's Board of Directors but in no event less than twenty-four hours) of any meeting of SBB's Board of Directors at which SBB's Board of Directors is reasonably expected to consider any Acquisition Proposal to determine whether such Acquisition Proposal is a Superior Proposal. For purposes of this Agreement, "Superior Proposal" shall mean an unsolicited, bona fide written offer made by a Person (other than an Affiliate of SBB) to consummate any of the following transactions: (i) a merger or consolidation involving SBB pursuant to which the shareholders of SBB immediately preceding such transaction hold less than 50% of the equity interest in the surviving or resulting entity of such transaction or (ii) the acquisition by any Person (including by way of a tender offer or an exchange offer or a two step transaction involving a tender offer followed with reasonable promptness by a cash-out merger involving SBB), directly or indirectly, of ownership of 100% of the then outstanding shares of SBB Stock, on terms that the disinterested members of SBB's Board of Directors determines, in its reasonable judgment (based on the written advice of its financial adviser) to be more favorable to SBB Shareholders than the terms of the Consolidation; provided, however, that any such offer shall not be deemed to be a "Superior Proposal" if any financing required to consummate the transaction contemplated by such offer is not committed and is not likely in the reasonable judgment of SBB's Board of Directors (based upon the written advice of its financial adviser) to be obtained by such third party on a timely basis.

        5.5  Filings.  Each of SBB and NMB will use its reasonable best efforts and will cooperate with the other in the preparation and filing, as soon as practicable, of all documents and applications required to obtain regulatory approvals and consents for the Consolidation by September 30, 2001, including, but not limited to filings with the OCC and the FRB (the "Acquisition Application") by July 31, 2001 and publishing the required public notices of the Consolidation.

        5.8  Updated Schedules.  Prior to the Closing, SBB shall update Schedules 3.6, 3.17. 3.18 and 3.19 to a date reasonably proximate to the Closing Date (instead of the Current Balance Sheet Date) and shall deliver to NMB a draft of such updated schedules at least two Business Days prior to the Closing and the final updated schedules (the "Updated Schedules") at the Closing.

        5.15  Baxter Fentriss Agreement.  SBB agrees that, without the prior written consent of NMB, it will not reimburse, pay or incur expense reimbursement obligations to Baxter Fentriss & Company in excess of an aggregate of $1,500 after the date hereof under the Baxter Fentriss Agreement, and will take any actions necessary to prohibit Baxter Fentriss from becoming entitled under the Baxter Fentriss Agreement to expense reimbursements in excess of an aggregate of $1,500 after the date hereof.
