Merger Consideration. Subject to the provisions of this Agreement, at the Effective Time, automatically by virtue of the Merger and without any action on the part of any party or stockholder: (a) Outstanding USBC Common Stock. Each share, excluding Treasury Shares, of the common stock, par value $5.00 per share, of USBC (the "USBC Common Stock"), issued and outstanding immediately prior to the Effective Time shall become and be converted into the right to receive 0.755 shares (subject to possible adjustment as set forth in Section 3.05, the "Exchange Ratio") of the common stock, par value $1.25 per share, of FBS ("FBS Common Stock"). (b) Outstanding USBC Preferred Stock. Each share of USBC 8 1/8% Cumulative Preferred Stock, Series A, without par value, liquidation preference $25 per share (the "USBC Preferred Stock"), excluding any Treasury Shares, issued and outstanding immediately prior to the Effective Time, shall become and be converted into one share of a new series of preferred stock of FBS ("New FBS Preferred Stock") having terms (to be set forth in the Certificate of Designations) substantially identical to those of the USBC Preferred Stock. 8 (c) Outstanding FBS Common Stock. Each share of FBS Common Stock issued and outstanding immediately prior to the Effective Time shall be unchanged and shall remain issued and outstanding as common stock of the Surviving Corporation. (d) Treasury Shares. Each of the shares of USBC Stock held as Treasury Shares immediately prior to the Effective Time shall be canceled and retired at the Effective Time and no consideration shall be issued in exchange therefor. 3.02. Rights as Stockholders; Stock Transfers. At the Effective Time, holders of USBC Stock shall cease to be, and shall have no rights as, stockholders of USBC, other than to receive any dividend or other distribution with respect to such USBC Stock with a record date occurring prior to the Effective Time and the consideration provided under this Article III. After the Effective Time, there shall be no transfers on the stock transfer books of USBC or the Surviving Corporation of shares of USBC Stock. 3.03. Fractional Shares. Notwithstanding any other provision hereof, no fractional shares of FBS Common Stock and no certificates or scrip therefor, or other evidence of ownership thereof, will be issued in the Merger; instead, FBS shall pay to each holder of USBC Common Stock who would otherwise be entitled to a fractional share of FBS Common Stock (after taking into account all Old Certificates delivered by such holder) an amount in cash (without interest) determined by multiplying such fraction by the average of the last sale prices of FBS Common Stock, as reported by the NYSE Composite Transactions Reporting System (as reported in The Wall Street Journal or, if not reported therein, in another authoritative source), for the five NYSE trading days immediately preceding the Effective Date. 3.04. Exchange Procedures. (a) At or prior to the Effective Time, FBS shall deposit, or shall cause to be deposited, with a bank or trust company which may be a Subsidiary of FBS (the "Exchange Agent"), for the benefit of the holders of certificates formerly representing shares of USBC Common Stock ("Old Certificates"), for exchange in accordance with this Article III, certificates representing the shares of FBS Common Stock ("New Certificates") and an estimated amount of cash (such cash and New Certificates, together with any dividends or distributions with a record date occurring after the Effective Date with respect thereto (without any interest on any such cash, dividends or distributions), being hereinafter referred to as the "Exchange Fund") to be paid pursuant to this Article III in exchange for outstanding shares of USBC Common Stock. Certificates evidencing shares of USBC Preferred Stock will remain outstanding and will represent the shares of New FBS Preferred Stock into which such shares of USBC Preferred Stock are converted on the Effective Date. (b) As promptly as practicable after the Effective Date, FBS shall send or cause to be sent to each former holder of record of shares (other than Treasury Shares) of USBC Common Stock immediately prior to the Effective Time transmittal materials for use in exchanging such stockholder's Old Certificates for the consideration set forth in this 9 Article III. FBS shall cause the New Certificates into which shares of a stockholder's USBC Common Stock are converted on the Effective Date and/or any check in respect of any fractional share interests or dividends or distributions which such person shall be entitled to receive to be delivered to such stockholder upon delivery to the Exchange Agent of Old Certificates representing such shares of USBC Common Stock (or indemnity reasonably satisfactory to FBS and the Exchange Agent, if any of such certificates are lost, stolen or destroyed) owned by such stockholder. No interest will be paid on any such cash to be paid in lieu of fractional share interests or in respect of dividends or distributions which any such person shall be entitled to receive pursuant to this Article III upon such delivery. (c) Notwithstanding the foregoing, neither the Exchange Agent nor any party hereto shall be liable to any former holder of USBC Stock for any amount properly delivered to a public official pursuant to applicable abandoned property, escheat or similar laws. (d) No dividends or other distributions with respect to FBS Common Stock with a record date occurring after the Effective Time shall be paid to the holder of any unsurrendered Old Certificate representing shares of USBC Common Stock converted in the Merger into the right to receive shares of such FBS Common Stock until the holder thereof shall be entitled to receive New Certificates in exchange therefor in accordance with this Article III, and no such shares of FBS Common Stock shall be eligible to vote until the holder of Old Certificates is entitled to receive New Certificates in accordance with this Article III. After becoming so entitled in accordance with this Article III, the record holder thereof also shall be entitled to receive any such dividends or other distributions, without any interest thereon, which theretofore had become payable with respect to shares of FBS Common Stock such holder had the right to receive upon surrender of the Old Certificate. (e) Any portion of the Exchange Fund that remains unclaimed by the stockholders of USBC for twelve months after the Effective Time shall be paid to FBS. Any stockholders of USBC who have not theretofore complied with this Article III shall thereafter look only to FBS for payment of the shares of FBS Common Stock, cash in lieu of any fractional shares and unpaid dividends and distributions on the FBS Common Stock deliverable in respect of each share of USBC Common Stock such stockholder holds as determined pursuant to this Agreement, in each case, without any interest thereon. 3.05. Anti-Dilution Provisions. In the event FBS changes (or establishes a record date for changing) the number of shares of FBS Common Stock issued and outstanding prior to the Effective Date as a result of a stock split, stock dividend, recapitalization or similar transaction with respect to the outstanding FBS Common Stock and the record date therefor shall be prior to the Effective Date, the Exchange Ratio shall be proportionately adjusted. 3.06. Options. At the Effective Time, all employee and director stock options to purchase shares of USBC Common Stock (each, a "USBC Stock Option"), which are then outstanding and unexercised, shall cease to represent a right to acquire shares of USBC Common Stock and shall be converted automatically into options to purchase shares of FBS Common Stock, and FBS shall assume each such USBC Stock Option subject to the terms thereof, including but not limited to the accelerated vesting of such options which shall occur in connection with and by virtue of the Merger as and to the extent required by the plans and agreements governing such USBC Stock Options; provided, however, that from and after the Effective Time, (i) the number of shares of FBS Common Stock purchasable upon exercise of such USBC Stock Option shall be equal to the number of shares of USBC Common Stock that were purchasable under such USBC Stock Option immediately prior to the Effective Time multiplied by the Exchange Ratio, and rounding to the nearest whole share, and (ii) the per share exercise price under each such USBC Stock Option shall be adjusted by dividing the per share exercise price of each such USBC Stock Option by the Exchange Ratio, and rounding down to the nearest cent. The terms of each USBC Stock Option shall, in accordance with its terms, be subject to further adjustment as appropriate to reflect any stock split, stock dividend, recapitalization or other similar transaction with respect to FBS Common Stock on or subsequent to the Effective Date. Notwithstanding the foregoing, each USBC Stock Option which is intended to be an "incentive stock option" (as defined in Section 422 of the Code) shall be adjusted in accordance with the requirements of Section 424 of the Code. Accordingly, with respect to any incentive stock options, fractional shares shall be rounded down to the nearest whole number of shares and where necessary the per share exercise price shall be rounded down to the nearest cent.

Provided the other party has cooperated as required above, each party agrees to file the Joint Proxy Statement in preliminary form with the SEC as promptly as reasonably practicable, and FBS agrees to file the Registration Statement with the SEC as soon as reasonably practicable after any SEC comments with respect to the preliminary Joint Proxy Statement are resolved.

Each of USBC and FBS further agrees that if it shall become aware prior to the Effective Date of any information furnished by it that would cause any of the statements in the Joint Proxy Statement to be false or misleading with respect to any material fact, or to omit to state any material fact necessary to make the statements therein not false or misleading, to promptly inform the other party thereof and to take the necessary steps to correct the Joint Proxy Statement. (c) In the case of FBS, FBS will advise USBC, promptly after FBS receives notice thereof, of the time when the Registration Statement has become effective or any supplement or amendment has been filed, of the issuance of any stop order or the suspension of the qualification of the FBS Stock for offering or sale in any jurisdiction, of the initiation or threat of any proceeding for any such purpose, or of any request by the SEC for the amendment or supplement of the Registration Statement or for additional information. 6.04.

Acquisition Proposals. It shall not, and shall cause its Subsidiaries and its and its Subsidiaries' officers, directors, agents, advisors and affiliates not to, solicit or encourage inquiries or proposals with respect to, or engage in any negotiations concerning, or provide any confidential information to, or have any discussions with, any person relating to, any Takeover Proposal. It shall immediately cease and cause to be terminated any activities, discussions or negotiations conducted prior to the date of this Agreement with any parties other than FBS or USBC, as applicable, with respect to any of the foregoing. It shall promptly (within 24 hours) advise the other party following the receipt by it of any Takeover Proposal and the substance thereof (including the identity of the person making such Takeover Proposal), and advise the other party of any developments with respect to such Takeover Proposal immediately upon the occurrence thereof. 6.07. Affiliate Agreements.

(b) Each of USBC and FBS shall use its respective reasonable best efforts to cause each person who may be deemed to be a USBC Affiliate or an FBS Affiliate, as the case may be, to execute and deliver to USBC and FBS on or before the date of mailing of the Joint Proxy Statement an agreement in the form attached hereto as Exhibit C or Exhibit D, respectively. 6.08. Takeover Laws. No party shall take any action that would cause the transactions contemplated by this Agreement and, in the case of FBS, the FBS Option Agreement, and, in the case of USBC, the USBC Option Agreement, to be subject to requirements imposed by any Takeover Law and each of them shall take all necessary steps within its control to exempt (or ensure the continued exemption of) the transactions contemplated by this Agreement and, in the case of FBS, the FBS Option Agreement, and, in the case of USBC, the USBC Option Agreement, from, or if necessary challenge the validity or applicability of, any applicable Takeover Law, as now or hereafter in effect, including, without limitation, Section 203 of the DGCL, Sections 60.801-60.816 and 60.825-60.845 of the OBCA, or any other Takeover Laws that purport to apply to this Agreement, the USBC Option Agreement, the FBS Option Agreement or the transactions contemplated hereby or thereby. 6.09. No Rights Triggered. Each of USBC and FBS shall take all reasonable steps necessary to ensure that the entering into of this Agreement and, in the case of FBS, the FBS Option Agreement, and, in the case of USBC, the USBC Option Agreement, and the consummation of the transactions contemplated hereby and thereby and any other action or combination of actions, or any other transactions contemplated hereby and thereby, do not and will not result in the grant of any rights to any person (i) under its articles or certificate of incorporation or by-laws or (ii) under any material agreement to which it or any of its Subsidiaries is a party (except as expressly contemplated by (A) the mandatory provisions under its stock option plans or (B) the FBS Option Agreement or the USBC Option Agreement, as applicable). 6.10. Shares Listed. In the case of FBS, FBS shall use its best efforts to (i) list, prior to the Effective Date, on the NYSE, subject to official notice of issuance, the shares of FBS Common Stock to be issued to the holders of USBC Common Stock in the Merger and (ii) if the USBC Preferred Stock is quoted on NASDAQ immediately prior to the Effective Time, prior to the Effective Date, either (at FBS's discretion) list on the NYSE, subject to official notice of issuance, or provide for the quotation on NASDAQ of the shares of New FBS Preferred Stock to be issued to the holders of USBC Preferred Stock in the Merger. 6.11. Regulatory Applications. (a) FBS and USBC and their respective Subsidiaries shall cooperate and use their respective reasonable best efforts (i) to prepare all documentation, to effect all filings and to obtain all permits, consents, approvals and authorizations of all third parties and Regulatory Authorities necessary to consummate the transactions contemplated by this Agreement, including, without limitation, any such approvals or authorizations required by the Federal Reserve Board, the OCC and, to the extent necessary, the regulatory authorities of the States in which USBC and its Subsidiaries operate, and (ii) to cause the Merger to be consummated as expeditiously as reasonably practicable. Provided USBC has cooperated as required above, FBS agrees to file the requisite applications to be filed by it with the Federal Reserve, the OCC and, to the extent necessary, the regulatory authorities of the States in which USBC and its Subsidiaries operate, as promptly as reasonably practicable. Each of FBS and USBC shall have the right to review in advance, and to the extent practicable each will consult with the other, in each case subject to applicable laws relating to the exchange of information, with respect to, all material written information submitted to any third party or any Regulatory Authority in connection with the transactions contemplated by this Agreement. In exercising the foregoing right, each of the parties hereto agrees to act reasonably and as promptly as practicable. Each party hereto agrees that it will consult with the other party hereto with respect to the obtaining of all material permits, consents, approvals and authorizations of all third parties and Regulatory Authorities necessary or advisable to consummate the transactions contemplated by this Agreement and each party will keep the other party apprised of the status of material matters relating to completion of the transactions contemplated hereby. (b) Each party agrees, upon request, to furnish the other party with all information concerning itself, its Subsidiaries, directors, officers and stockholders and such other matters as may be reasonably necessary or advisable in connection with any filing, notice or application made by or on behalf of such other party or any of its Subsidiaries to any third party or Regulatory Authority. 6.12. Indemnification. (a) Following the Effective Date and without limitation as to time, FBS shall indemnify, defend and hold harmless the present and former directors and officers of USBC and its Subsidiaries (each, an "Indemnified Party") against all costs or expenses (including reasonable attorneys' fees), judgments, fines, losses, claims, damages or liabilities (collectively, "Costs") incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of actions or omissions occurring at or prior to the Effective Time (including, without limitation, the transactions contemplated by this Agreement) to the fullest extent that USBC is permitted to indemnify its directors and officers under the laws of the State of Oregon, the USBC Articles and USBC's by-laws as in effect on the date hereof (and FBS shall also advance expenses (including expenses constituting Costs described in Section 6.12(e)) as incurred to the fullest extent permitted under applicable law; provided that any determination required to be made with respect to whether an officer's or director's conduct complies with the standards set forth under Oregon law, the USBC Articles and USBC's by-laws shall be made by independent counsel (which shall not be counsel that provides material services to FBS) selected by FBS and reasonably acceptable to such officer or director; and provided, further, that in the absence of applicable Oregon judicial precedent to the contrary, such counsel, in making such determination, shall presume such officer's or director's conduct complied with such standard and FBS shall have the burden to demonstrate that such officer's or director's conduct failed to comply with such standard. (b) For a period of three years from the Effective Time, FBS shall use its best efforts to provide that portion of director's and officer's liability insurance that serves to reimburse the present and former officers and directors of USBC or any of its Subsidiaries (determined as of the Effective Time) (as opposed to USBC) with respect to claims against such directors and officers arising from facts or events which occurred before the Effective Time, which insurance shall contain at least the same coverage and amounts, and contain terms and conditions no less advantageous, as that coverage currently provided by USBC; provided, however, that in no event shall FBS be required to expend more than 200 percent of the current amount expended by USBC (the "Insurance Amount") to maintain or procure such directors and officers insurance coverage; provided, further, that if FBS is unable to maintain or obtain the insurance called for by this Section 6.12(b), FBS shall use its reasonable best efforts to obtain as much comparable insurance as is available for the Insurance Amount; provided, further, that officers and directors of USBC or any Subsidiary may be required to make application and provide customary representations and warranties to FBS's insurance carrier for the purpose of obtaining such insurance; and provided, further, that such coverage will have a single aggregate for such three-year period in an amount not less than the annual aggregate of such coverage currently provided by USBC. (c) Any Indemnified Party wishing to claim indemnification under Section 6.12(a), upon learning of any claim, action, suit, proceeding or investigation described above, shall promptly notify FBS thereof; provided that the failure so to notify shall not affect the obligations of FBS under Section 6.12(a) unless and to the extent such failure materially increases FBS's liability under such subsection (a). (d) If FBS or any of its successors or assigns shall consolidate with or merge into any other entity and shall not be the continuing or surviving entity of such consolidation or merger or shall transfer all or substantially all of its assets to any entity, then and in each 21 case, proper provision shall be made so that the successors and assigns of FBS shall assume the obligations set forth in this Section 6.12. (e) FBS shall pay all reasonable Costs, including attorneys' fees, that may be incurred by any Indemnified Party in enforcing the indemnity and other obligations provided for in this Section 6.12. The rights of each Indemnified Party hereunder shall be in addition to any other rights such Indemnified Party may have under applicable law. 6.13. Severance and Benefit Plans. (a) Until the transition to FBS's benefit plans as set forth below, FBS shall cause the Surviving Corporation and its Subsidiaries to provide employees of USBC and its Subsidiaries who become employees of the Surviving Corporation and its Subsidiaries with compensation and employee benefit plans, programs, arrangements and other perquisites (including, but not limited to, "employee benefit plans" within the meaning of section 3(3) of ERISA) ("Employee Benefit Plans") that are, in the aggregate, substantially the same as the compensation and Employee Benefit Plans provided to such individuals by USBC immediately prior to the Effective Date. Within two years following the Effective Time, FBS shall cause the Surviving Corporation and its Subsidiaries to provide USBC employees who are employees thereof with compensation and Employee Benefit Plans that are substantially the same as the compensation and Employee Benefit Plans provided to similarly situated employees of the Surviving Corporation or its Subsidiaries who were not employees of USBC; provided, however, FBS shall cause the Surviving Corporation and its Subsidiaries to take into account any co-payments or deductibles under USBC's health plans, as disclosed in USBC's Disclosure Schedule, and, with respect to any person covered by USBC's health plans, not impose any pre-existing condition exclusion to exclude from coverage any condition covered under USBC's health plans, as disclosed in USBC's Disclosure Schedule. For the purpose of determining eligibility to participate in Employee Benefit Plans, eligibility for benefit forms and subsidies and the vesting of benefits under such Employee Benefit Plans (including, but not limited to, any pension, severance, 401(k), vacation and sick pay), and for purposes of accrual of benefits under any severance, sick leave, vacation and other similar Employee Benefit Plans, FBS shall give effect to years of service (and for purposes of qualified and nonqualified pension plans, prior earnings) with USBC or its Subsidiaries, as the case may be, as if they were with FBS or its Subsidiaries. (b) Notwithstanding the foregoing, FBS shall, and shall cause its Subsidiaries to, honor in accordance with their terms all benefits (including retiree benefits, if any) that were vested as of the Effective Time under USBC's Employee Benefit Plans or under other contracts, arrangements, commitments or understandings described in USBC's Disclosure Schedule. (c) Individuals who are employees of USBC or any of its Subsidiaries (other than persons who have individual written employment agreements or change of control agreements with USBC or its Subsidiaries as specified in paragraph 6.13(c) of USBC's Disclosure Schedule (the "Change of Control Agreements")) immediately prior to the Effective Time and whose employment is terminated within two years after the Effective Time shall be entitled to receive cash severance benefits in an amount equal to the greater of (i) the amount of cash 22 severance benefits, if any, to which they would have been entitled under USBC's Employee Benefit Plans as in effect immediately prior to the Effective Time and (ii) the amount of cash severance benefits, if any, to which they would have been entitled under FBS's Employee Benefit Plans if they had been employees of FBS (and not been employees of USBC) immediately prior to the Effective Time and through the time of such termination; provided, that payment of this amount shall be in complete settlement of any amounts to which such employees would have been entitled under USBC's Employee Benefit Plans and FBS's Employee Benefit Plans. In computing the benefits payable pursuant to this Section 6.13(c), service with USBC and its Subsidiaries shall be treated as service with FBS and its Subsidiaries. For purposes of clause (ii) of the first sentence of this Section 6.13(c), (x) prior to the Effective Time USBC and FBS shall negotiate in good faith and mutually determine how to allocate different categories and levels of USBC employees among FBS's existing employment categories and levels, (y) severance payments shall be made using such procedures, and payable at such times, as reasonably determined by FBS in consultation with USBC, which procedures and times need not be identical to those provided for in either USBC's existing severance plans or in FBS's existing severance plans but in no way will such procedures have a material adverse impact on the rights of any such USBC employee, and (z) the events giving rise to entitlement to cash severance benefits shall be based on the occurrence of a "Partial Change of Control" (and not a "Change of Control") within the meaning of FBS's severance plans. The Change of Control Agreements (other than the agreements of Messers Cameron, Sznewajs and Duim, who are separately entering into agreements with FBS) shall remain in full force and effect except that FBS agrees that any of such agreements providing for severance benefits of two-times base salary and bonus and two years of benefits continuation and pension credit shall, at the Effective Time, be deemed amended to provide severance benefits of three times base salary and bonus, three years of benefits continuation and five years of pension credit. (d) Nothing in this Section 6.13 shall be interpreted as preventing FBS or its Subsidiaries from amending, modifying or terminating any Employee Benefit Plans or other contracts arrangements, commitments or understandings, in accordance with their terms and applicable law. (e) It is the express understanding and intention of USBC and FBS that no employee of USBC or FBS or other person shall be deemed to be a third party beneficiary, or have or acquire any right to enforce the provisions of this Section 6.13, and that nothing in this Agreement shall be deemed to constitute an Employee Benefit Plan or an amendment to an Employee Benefit Plan. 6.14. Accountants' Letters. Each of USBC and FBS shall use its best efforts to cause to be delivered to the other party, and such other party's directors and officers who sign the Registration Statement, a letter of Deloitte & Touche LLP and Ernst & Young LLP, respectively, independent auditors, dated (i) the date on which the Registration Statement shall become effective and (ii) a date shortly prior to the Effective Date, and addressed to such other party, and such directors and officers, in form and substance customary for "comfort" letters delivered by independent accountants in accordance with Statement of Accounting Standards No. 72. 6.15. Certain Director and Officer Positions. (a) Subject to Section 6.15(c), FBS agrees to cause all of the members of the USBC Board on the date hereof who are still members of the USBC Board immediately prior to the Effective Time and willing so to serve ("Former USBC Directors") to be elected or appointed as directors of FBS at, or as promptly as practicable after, the Effective Time (such appointment or election of Former USBC Directors to be as evenly distributed as possible among the classes of FBS directors). It is the intention of the parties that the size of the board of directors of the Surviving Corporation be substantially reduced as of the first annual meeting of stockholders of the Surviving Corporation following the Effective Time but that, in connection with such reduction, and thereafter until at least the third annual meeting of stockholders of the Surviving Corporation following the Effective Time, the Former USBC Directors constitute in the aggregate between 40% and 45% of the total number of directors of the Surviving Corporation then in office. (b) At the Effective Time,(i) Gerry B. Cameron shall be Chairman of the FBS Board for a term extending through December 31, 1998 and John F. Grundhofer shall continue to be President and Chief Executive Officer of FBS and (ii) Gary T. Duim and Robert D. Sznewajs shall each be a Vice Chairman of FBS. (c) FBS shall use all reasonable efforts to solicit the affirmative vote of the holders of at least 80% of the outstanding FBS Common Stock entitled to vote thereon at the FBS Meeting with respect to approval of the Board Size Amendment. In the event such approval is not obtained at the FBS Meeting, the parties agree that, notwithstanding the provisions of Section 6.15(a), FBS shall appoint or elect to the FBS Board the maximum number of Former USBC Directors (and in no event fewer than 10 Former USBC Directors) as would result in there being 24 FBS directors and FBS agrees to appoint the remaining Former USBC Director (as selected by the Chief Executive Officer of USBC) as an advisory director of the FBS Board entitled to fully participate at all FBS Board meetings to the fullest extent permitted by applicable law. FBS shall provide the advisory director with compensation, benefits and indemnification as if such person were a full member of the FBS Board. The parties agree that the Merger shall not be conditioned upon approval of the Board Size Amendment, and if such approval is not obtained at the FBS Meeting, the FBS Certificate as amended at the Effective Time, shall not include the Board Size Amendment. 6.16. Charitable Contributions. Following the Effective Date, FBS shall maintain the aggregate level of charitable contributions historically maintained by USBC in USBC markets. 6.17. Coordination of Dividends. Until the Effective Time, USBC and FBS shall coordinate with the other the declaration of any dividends or other distributions with respect to the USBC Common Stock and the FBS Common Stock and the record dates and payment dates relating thereto, it being the intention of the parties that holders of shares of USBC Common Stock or FBS Common Stock shall not receive more than one dividend, or fail to receive one dividend, for any single calendar quarter on their shares of USBC Common Stock (including any shares of FBS Common Stock received in exchange therefor in the Merger) or FBS Common Stock, as the case may be. 6.18. Notification of Certain Matters. Each of USBC and FBS shall give prompt notice to the other of any fact, event or circumstance known to it that (i) is reasonably likely, individually or taken together with all other facts, events and circumstances known to it, to result in any Material Adverse Effect with respect to it or (ii) would cause or constitute a material breach of any of its representations, warranties, covenants or agreements contained herein.

Regulatory Approvals. All regulatory approvals required to consummate the transactions contemplated hereby, including, without limitation, those specified in Section 5.03(r), shall have been obtained and shall remain in full force and effect and all statutory waiting periods in respect thereof shall have expired and no such approvals shall contain any conditions or restrictions which either the FBS Board or the USBC Board reasonably determines in good faith would, following the Effective Time, have a Material Adverse Effect on the Surviving Corporation and its Subsidiaries taken as a whole. 7.03. Third Party Consents. All consents or approvals of all persons (other than Regulatory Authorities) required for the consummation of the Merger shall have been obtained and shall be in full force and effect, unless the failure to obtain any such consent or approval is not reasonably likely to have, individually or in the aggregate, a Material Adverse Effect on USBC or FBS. 7.04. No Injunction, Etc.

Representations, Warranties And Covenants Of USBC. In the case of FBS's obligations: (a) each of the representations and warranties contained herein of USBC shall be true and correct as of the date of this Agreement and upon the Effective Date with the same effect as though all such representations and warranties had been made on the Effective Date, except for any such representations and warranties made as of a specified date, which shall be true and correct as of such date, in each case subject to the standard set forth in Section 5.02, (b) each and all of the agreements and covenants of USBC to be performed and complied with pursuant to this Agreement on or prior to the Effective Date shall have been duly performed and complied with in all respects (except to the extent that any failure so to comply would not be reasonably likely, individually or in the aggregate, to result in a Material Adverse Effect with respect to USBC), and (c) FBS shall have received a certificate signed by the Chief Financial Officer of USBC, dated the Effective Date, to the effect set forth in clauses (a) and (b) of this Section 7.07. 7.08.

In rendering such opinion, such counsel may require and rely upon representations and covenants including those contained in certificates of officers of FBS, USBC and others. 7.10. Certificate of Designations. The Certificate of Designations shall have been filed in accordance with Section 151 of the DGCL. 7.11. NYSE Listing.
