AGREEMENT
                                       AND

                             PLAN OF REORGANIZATION


         AGREEMENT AND PLAN OF REORGANIZATION (the "Agreement") entered into as
of the 6th day of July, 2000, by and between BRENTON BANKS, INC., an Iowa
corporation ("Company"), BRENTON BANK, an Iowa banking association ("Bank"), and
WELLS FARGO & COMPANY, a Delaware corporation ("Wells Fargo").

         WHEREAS, the parties hereto desire to effect a reorganization whereby a
wholly-owned subsidiary of Wells Fargo ("Merger Co.") will merge with and into
Company (the "Merger") pursuant to an agreement and plan of merger (the "Merger
Agreement") in substantially the form attached hereto as Exhibit A-1, which
provides, among other things, for the conversion of the shares of Common Stock
of Company of the par value of $2.50 per share ("Company Common Stock")
outstanding immediately prior to the time the Merger becomes effective in
accordance with the provisions of the Merger Agreement into the right to receive
shares of voting Common Stock of Wells Fargo of the par value of $1-2/3 per
share ("Wells Fargo Common Stock"), and

         WHEREAS, Wells Fargo desires that, immediately following the Merger,
Wells Fargo will contribute its newly-formed, wholly-owned bank subsidiary
("Interim Bank") to Company and, immediately thereafter, Interim Bank will merge
with and into Bank under the charter of Bank (the "Bank Merger") pursuant to an
agreement of merger (the "Bank Merger Agreement") in substantially the form
attached hereto as Exhibit A-2, which provides, among other things, for the
conversion and exchange of the shares of common stock of the Bank, par value of
$20 per share ("Bank Common Stock"), outstanding immediately prior to the time
the Bank Merger becomes effective in accordance with the provisions of the Bank
Merger Agreement and owned by shareholders other than Company into the right to
receive shares of Wells Fargo Common Stock, and

         NOW, THEREFORE, to effect such reorganization and in consideration of
the premises and the mutual covenants and agreements contained herein, the
parties hereto do hereby represent, warrant, covenant and agree as follows:

         1.  BASIC PLAN OF REORGANIZATION

         (a)  Reorganization.
              --------------

                  (i) Merger. Subject to the terms and conditions contained
         herein, Merger Co. will be merged by statutory merger with and into
         Company pursuant to the Merger Agreement, with Company as the surviving
         corporation, in which merger each share of Company Common Stock
         outstanding immediately prior to the Effective Time of the Merger (as
         defined in paragraph 1(e) below) (other than shares as to which
         statutory dissenters' appraisal rights have been exercised) will be
         converted into the right to receive, and exchanged for certificates
         representing the number





         of shares of Wells Fargo Common Stock determined by dividing
         $255,694,000 by the Wells Fargo Measurement Price, and dividing the
         result thereof by the number of shares of Company Common Stock then
         outstanding. The "Wells Fargo Measurement Price" is defined as the
         average of the closing prices of a share of Wells Fargo Common Stock on
         the New York Stock Exchange only, as reported by Bloomberg, for each of
         the 15 consecutive trading days ending on the day immediately preceding
         the meeting of Company shareholders required by paragraph 4(c)(i) of
         this Agreement.

                  (ii) Bank Merger. Following the Effective Time of the Merger
         and on the terms and conditions contained herein, Wells Fargo will
         contribute Interim Bank to Company and, immediately thereafter, Interim
         Bank will be merged with and into Bank under the charter of Bank
         pursuant to the Bank Merger Agreement, in which Bank Merger each share
         of Bank Common Stock outstanding immediately prior to the Effective
         Time of the Bank Merger (as defined in paragraph 1(e) below) (other
         than shares owned by the Company or as to which Iowa statutory
         dissenters' appraisal rights have been exercised) will be converted
         into and exchanged for a number of shares of Wells Fargo Common Stock
         determined by dividing $8,806,000 by the Wells Fargo Measurement Price,
         and dividing the result thereof by the number of shares of Bank Common
         Stock outstanding immediately prior to the time the Bank Merger becomes
         effective in accordance with the provisions of the Bank Merger
         Agreement and owned by shareholders other than Company.

         (b) Conversion of Company Options. At the Effective Time of the Merger,
each option granted by Company to purchase shares of Company Common Stock under
Company's 1996 Stock Option Plan (the "Company Stock Option Plan") which is
outstanding and unexercised immediately prior to the Effective Date of the
Merger (each, a "Company Stock Option"), shall be converted automatically into
an option to purchase shares of Wells Fargo Common Stock (each, a "Substitute
Option") in an amount and at an exercise price determined as provided below (and
otherwise subject to the terms of the Company Stock Option Plan).

                  (i) The number of shares of Wells Fargo Common Stock to be
         subject to the Substitute Option shall be the product of the number of
         shares of Company Common Stock subject to the Company Stock Option and
         the number of shares of Wells Fargo Common Stock issuable for each
         share of Company Common Stock as determined in accordance with
         paragraph 1(a)(i) above (the "Merger Exchange Ratio"), provided that
         any fractional shares of Wells Fargo Common Stock resulting from such
         multiplication shall be rounded down to the nearest whole share; and

                  (ii) The exercise price per share of Wells Fargo Common Stock
         under the Substitute Option shall be equal to the exercise price per
         share of Company Common Stock under the Company Stock Option divided by
         the Merger Exchange Ratio, provided that such exercise price shall be
         rounded to the nearest cent.

The adjustment provided herein with respect to any options that are "incentive
stock options" (as defined in Section 422 of the Internal Revenue Code of 1986,
as amended (the "Code")) shall be and is intended to be effected in a manner
which is consistent with Section 424(a) of the Code.

         (c) Wells Fargo Common Stock Adjustments. If, between the date hereof
and the Effective Time of the Merger as defined below, shares of Wells Fargo
Common Stock shall be changed into a

                                       -2-





different number of shares or a different class of shares by reason of any
reclassification, recapitalization, split-up, combination, exchange of shares or
readjustment, or if a stock dividend thereon shall be declared with a record
date within such period (a "Common Stock Adjustment"), then the number of shares
of Wells Fargo Common Stock issuable pursuant to subparagraphs (a) and (b)
above, will be appropriately and proportionately adjusted so that the number of
such shares of Wells Fargo Common Stock issuable in the Merger and the Bank
Merger will equal the number of shares of Wells Fargo Common Stock which holders
of shares of Company Common Stock would have received pursuant to such Common
Stock Adjustment had the record date therefor been immediately following the
Effective Time of the Merger.

         (d) Fractional Shares. No fractional shares of Wells Fargo Common Stock
and no certificates or scrip certificates therefor shall be issued to represent
any such fractional interest, and any holder thereof shall be paid an amount of
cash equal to the product obtained by multiplying the fractional share interest
to which such holder is entitled by the average of the closing prices of a share
of Wells Fargo Common Stock on the New York Stock Exchange only as reported by
Bloomberg for each of the five (5) consecutive trading days ending on the day
immediately preceding the meeting of Company shareholders required by paragraph
4(c)(i) of this Agreement.

         (e) Mechanics of Closing Merger and the Bank Merger. Subject to the
terms and conditions set forth herein, the Merger Agreement shall be executed
and it or Articles of Merger or a Certificate of Merger shall be filed with the
Secretary of State of the State of Iowa within ten (10) business days following
the satisfaction or waiver of all conditions precedent set forth in Sections 6
and 7 of this Agreement or on such other date as may be agreed to by the parties
(the "Closing Date"), provided that the Closing Date shall not occur on the last
business day of a calendar month. Each of the parties agrees to use its best
efforts to cause the Merger to be completed as soon as practicable after the
receipt of final regulatory approval of the Merger and the expiration of all
required waiting periods. The time that the filing referred to in the first
sentence of this paragraph is made is herein referred to as the "Time of
Filing." The day on which such filing is made and accepted is herein referred to
as the "Effective Date of the Merger." The "Effective Time of the Merger" shall
be 11:59 p.m. Des Moines, Iowa time on the Effective Date of the Merger. At the
Effective Time of the Merger on the Effective Date of the Merger, the separate
existence of Merger Co. shall cease and Merger Co. will be merged with and into
Company pursuant to the Merger Agreement. The Bank Merger shall become effective
at 12:01 a.m. (the "Effective Time of the Bank Merger") on the date specified in
the Bank Merger Agreement, which date shall be the first business day after the
Effective Date of the Merger (the "Effective Date of the Bank Merger"). At the
Effective Time of the Bank Merger on the Effective Date of the Bank Merger, the
separate existence of Interim Bank shall cease and Interim Bank will be merged
with and into Bank pursuant to the Bank Merger Agreement.

         The closing of the transactions contemplated by this Agreement and the
Merger Agreement (the "Closing") shall take place on the Closing Date at the
offices of Wells Fargo, Norwest Center, Sixth and Marquette, Minneapolis,
Minnesota.

         (f) Reservation of Right to Revise Structure. At Wells Fargo's
election, the Merger (or the Bank Merger) may alternatively be structured so
that (1) Company is merged with and into (or Bank is merged with) any other
direct or indirect wholly owned subsidiary of Wells Fargo, (2) any direct or
indirect wholly owned subsidiary of Wells Fargo is merged with and into Company
(or merged with Bank), or (3) Company is merged with and into Wells Fargo;
provided, however, that no such change shall (A) alter or change the amount or
kind of consideration to be issued to Company's shareholders in the Merger (or
to

                                       -3-





Bank's shareholders in the Bank Merger) or under such alternative structure (the
"Consideration"), (B) adversely affect the tax treatment of Company's
shareholders as a result of receiving the Consideration or prevent the parties
from obtaining the opinion referred to in paragraph 6(h), or (C) materially
impede or delay consummation of the Merger or the Bank Merger. In the event of
such election, the parties agree to execute an appropriate amendment to this
Agreement in order to reflect such election.

         2. REPRESENTATIONS AND WARRANTIES OF COMPANY AND BANK. Company (and
Bank, but only as to representations and warranties concerning the Bank)
represent and warrant to Wells Fargo as follows:

         (a) Organization and Authority. Company is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Iowa, is duly qualified to do business and is in good standing in all
jurisdictions where its ownership or leasing of property or the conduct of its
business requires it to be so qualified and failure to be so qualified would
have a material adverse effect on Company and the Company Subsidiaries (as
defined in paragraph 2(b) below) taken as a whole and has corporate power and
authority to own its properties and assets and to carry on its business as it is
now being conducted. Company is a bank holding company registered under the Bank
Holding Company Act of 1956, as amended (the "BHC Act") and a savings and loan
holding company under the Savings and Loan Holding Company Act (the "SLHC Act").
Company has furnished Wells Fargo true and correct copies of its articles of
incorporation and by-laws, as amended.

         (b) Company's Subsidiaries. Schedule 2(b) sets forth a complete and
correct list of all of Company's subsidiaries as of the date hereof
(individually a "Company Subsidiary" and collectively the "Company
Subsidiaries"), all shares of the outstanding capital stock of each of which,
except as set forth on Schedule 2(b), are owned directly or indirectly by
Company. No equity security of any Company Subsidiary is or may be required to
be issued by reason of any option, warrant, scrip, preemptive right, right to
subscribe to, call or commitment of any character whatsoever relating to, or
security or right convertible into, shares of any capital stock of such
subsidiary, and there are no contracts, commitments, understandings or
arrangements by which any Company Subsidiary is bound to issue additional shares
of its capital stock, or any option, warrant or right to purchase or acquire any
additional shares of its capital stock. Subject to the Iowa Business Corporation
Act and the Iowa Banking Act, all of such shares so owned by Company are fully
paid and nonassessable and are owned by it free and clear of any lien, claim,
charge, option, encumbrance or agreement with respect thereto. Each Company
Subsidiary is a corporation or federal or state banking association duly
organized, validly existing, duly qualified to do business and in good standing
under the laws of its jurisdiction of incorporation, and has corporate power and
authority to own or lease its properties and assets and to carry on its business
as it is now being conducted. Except as set forth on Schedule 2(b), Company does
not own beneficially, directly or indirectly, more than 5% of any class of
equity securities or similar interests of any corporation, bank, business trust,
association or similar organization, and is not, directly or indirectly, a
partner in any partnership or party to any joint venture.

         (c) Capitalization. The authorized capital stock of Company consists of
(i) 500,000 shares of preferred stock, par value $1.00 per share, of which, as
of the close of business on March 31, 2000, no shares were outstanding, and (ii)
50,000,000 shares of common stock, $2.50 par value, of which, as of the close of

$20 per share, of which as of the close of business on March 31, 2000, 345,200
shares were outstanding. As of the date hereof, there are outstanding options to
purchase an aggregate of 1,422,221 shares of Company Common Stock under the

                                       -4-





Company Stock Option Plan. The maximum number of shares of Company Common Stock
(assuming for this purpose that phantom shares and other share-equivalents
constitute Company Common Stock) that would be outstanding as of the Effective
Date of the Merger if all options, warrants, conversion rights and other rights
with respect thereto were exercised is 21,783,222. All of the outstanding shares
of capital stock of Company have been duly and validly authorized and issued and
are fully paid and nonassessable. Except as set forth on Schedule 2(c), there
are no outstanding subscriptions, contracts, conversion privileges, options,
warrants, calls, plans, preemptive rights or other rights obligating Company or
any Company Subsidiary to issue, sell or otherwise dispose of, or to purchase,
redeem or otherwise acquire, any shares of capital stock of Company or any
Company Subsidiary. Since March 31, 2000 no shares of Company capital stock have
been purchased, redeemed or otherwise acquired, directly or indirectly, by
Company or any Company Subsidiary and, except as set forth on Schedule 2(c), no
dividends or other distributions have been declared, set aside, made or paid to
the shareholders of Company.

approvals of its shareholders, to carry out its obligations hereunder and
thereunder. The execution, delivery and performance of this Agreement and the
Merger Agreement by Company and the consummation of the transactions
contemplated hereby and thereby have been duly authorized by the Board of

regulation, this Agreement and the Bank Merger Agreement are valid and binding
obligations of Bank enforceable against Bank in accordance with their respective
terms.

         Except as set forth on Schedule 2(d), neither the execution, delivery
and performance by Company and Bank of this Agreement, the Merger Agreement, or
Bank Merger Agreement, as applicable, nor the consummation of the transactions
contemplated hereby and thereby, nor compliance by Company or Bank with any of

         (e) Company Financial Statements. The consolidated balance sheets of
Company and Company's Subsidiaries as of December 31, 1999 and 1998 and related
consolidated statements of income, changes in shareholders' equity and
comprehensive income and cash flows for the three years ended December 31, 1999,

"SEC"), and the unaudited consolidated balance sheets of Company and Company's
Subsidiaries as of March 31, 2000 and the related unaudited consolidated

the SEC (collectively, the "Company Financial Statements"), have been prepared
in accordance with generally accepted accounting principles applied on a
consistent basis and present fairly (subject, in the case of financial
statements for interim periods, to normal recurring adjustments) the
consolidated financial position of Company and Company's Subsidiaries at the
dates and the consolidated results of operations and cash flows of Company and
Company's Subsidiaries for the periods stated therein.

         (f) Reports. Since December 31, 1995, Company and each Company
Subsidiary has filed all reports, registrations and statements, together with
any required amendments thereto, that it was required to file, if any, with (i)
the SEC, including, but not limited to, Forms 10-K, Forms 10-Q and proxy

any applicable state securities or banking or thrift authorities. All such
reports and statements filed with any such regulatory body or authority are

and regulations promulgated by the SEC, the Federal Reserve Board, the FDIC, the
Comptroller, the OTS and applicable state securities or banking or thrift
authorities, as the case may be, and did not contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary in order to make the statements therein, in light of the circumstances
under which they were made, not misleading. Copies of all the Company Reports
have been made available to Wells Fargo by Company.

         (g) Properties and Leases. Except as may be reflected in the Company
Financial Statements and except for any lien for current taxes not yet
delinquent, Company and each Company Subsidiary have good title free and clear
of any material liens, claims, charges, options, encumbrances or similar

                                       -6-





restrictions to all the real and personal property reflected in Company's
consolidated balance sheet as of March 31, 2000 included in Company's Quarterly
Report on Form 10-Q for the period then ended, and all real and personal
property acquired since such date, except such real and personal property as has
been disposed of in the ordinary course of business. All leases of real property
and all other leases material to Company or any Company Subsidiary pursuant to
which Company or such Company Subsidiary, as lessee, leases real or personal
property are valid and effective in accordance with their respective terms, and
there is not, under any such lease, any material existing default by Company or
such Company Subsidiary or any event which, with notice or lapse of time or
both, would constitute such a material default. Substantially all Company's and
each Company Subsidiary's buildings and equipment in regular use have been well
maintained and are in good and serviceable condition, reasonable wear and tear
excepted.

         (h) Taxes. Each of Company and the Company Subsidiaries has filed all
federal, state, county, local and foreign tax returns, including information

those with respect to income, withholding, social security, unemployment,
workers compensation, franchise, ad valorem, premium, excise and sales taxes,
and no taxes shown on such returns to be owed by it or assessments received by
it are delinquent. The federal income tax returns of Company and the Company
Subsidiaries for the fiscal year ended December 31, 1995, and for all fiscal
years prior thereto, are for the purposes of routine audit by the Internal
Revenue Service closed because of the statute of limitations, and no claims for
additional taxes for such fiscal years are pending. Except only as set forth on
Schedule 2(h), (i) neither Company nor any Company Subsidiary is a party to any
pending action or proceeding, nor is any such action or proceeding threatened by
any governmental authority, for the assessment or collection of taxes, interest,
penalties, assessments or deficiencies and (ii) no issue has been raised by any
federal, state, local or foreign taxing authority in connection with an audit or
examination of the tax returns, business or properties of Company or any Company
Subsidiary which has not been settled, resolved and fully satisfied. Each of
Company and the Company Subsidiaries has paid all taxes owed or which it is
required to withhold from amounts owing to employees, creditors or other third
parties. The consolidated balance sheet as of March 31, 2000, referred to in
paragraph 2(e) hereof, includes adequate provision for all accrued but unpaid
federal, state, county, local and foreign taxes, interest, penalties,
assessments or deficiencies of Company and the Company Subsidiaries with respect
to all periods through the date thereof.

         (i) Absence of Certain Changes. Since December 31, 1999 there has been
no change in the business, financial condition or results of operations of
Company or any Company Subsidiary, which has had, or may reasonably be expected
to have, a material adverse effect on the business, financial condition or
results of operations of Company and the Company Subsidiaries taken as a whole.

         (j) Commitments and Contracts. Except as set forth on Schedule 2(j),
neither Company nor any Company Subsidiary is a party or subject to any of the
following (whether written or oral, express or implied):

                  (i) any employment contract or understanding (including any
         understandings or obligations with respect to severance or termination
         pay, liabilities or fringe benefits) with any present or former
         officer, director, employee or consultant (other than those that are
         terminable at will by Company or such Company Subsidiary);


                                       -7-





                  (ii) any plan, contract or understanding providing for any
         bonus, pension, option, deferred compensation, retirement payment,
         profit sharing or similar arrangement with respect to any present or
         former officer, director, employee or consultant;

                  (iii)  any labor contract or agreement with any labor union;

                  (iv) any contract containing covenants that limit the ability
         of Company or any Company Subsidiary to compete in any line of business
         or with any person or which involve any restriction of the geographical
         area in which, or method by which, Company or any Company Subsidiary
         may carry on its business (other than as may be required by law or
         applicable regulatory authorities);

                  (v) any other contract or agreement which is a "material
         contract" within the meaning of Item 601(b)(10) of Regulation S-K; or

                  (vi) any real property lease and any other lease with annual
         rental payments aggregating $50,000 or more; or

                  (vii) any agreement or commitment with respect to the
         Community Reinvestment Act with any state or federal bank regulatory
         authority or any other party; or

                  (viii) any current or past agreement, contract or
         understanding with any current or former director, officer, employee,
         consultant, financial adviser, broker, dealer, or agent providing for
         any rights of indemnification in favor of such person or entity.

         (k) Litigation and Other Proceedings. Company has furnished Wells Fargo
copies of (i) all attorney responses to the request of the independent auditors
for Company with respect to loss contingencies as of December 31, 1999 in
connection with the Company Financial Statements, and (ii) a written list of
legal and regulatory proceedings filed against Company or any Company Subsidiary
since said date. There is no pending or, to the best knowledge of Company,
threatened, claim, action, suit, investigation or proceeding, against Company or
any Company Subsidiary, nor is Company or any Company Subsidiary subject to any
order, judgment or decree, except for matters which, in the aggregate, will not
have, or cannot reasonably be expected to have, a material adverse effect on the
business, financial condition or results of operations of Company and the
Company Subsidiaries taken as a whole.

         (l) Insurance. Company and each Company Subsidiary are presently
insured, and during each of the past five calendar years (or during such lesser
period of time as Company has owned such Company Subsidiary) have been insured,
for reasonable amounts with financially sound and reputable insurance companies
against such risks as companies engaged in a similar business would, in
accordance with good business practice, customarily be insured and has
maintained all insurance required by applicable law and regulation.

         (m) Compliance with Laws. Company and each Company Subsidiary have all

suspension or cancellation of any of them is threatened; and all such filings,
applications and registrations are current. The conduct by Company and each
Company Subsidiary of its business and the condition and use of its properties
does not violate or infringe, in any respect material to any such business, any
applicable domestic (federal, state or local) or foreign law, statute,
ordinance, license or regulation. Neither Company nor any Company Subsidiary is
in default under any order, license, regulation or demand of any federal, state,
municipal or other governmental agency or with respect to any order, writ,
injunction or decree of any court. Except for statutory or regulatory
restrictions of general application and except as set forth on Schedule 2(m), no
federal, state, municipal or other governmental authority has placed any
restriction on the business or properties of Company or any Company Subsidiary
which reasonably could be expected to have a material adverse effect on the
business or properties of Company and the Company Subsidiaries taken as a whole.

         (n) Labor. No work stoppage involving Company or any Company Subsidiary
is pending or, to the best knowledge of Company, threatened. Neither Company nor
any Company Subsidiary is involved in, or threatened with or affected by, any
labor dispute, arbitration, lawsuit or administrative proceeding that could
materially and adversely affect the business of Company or such Company
Subsidiary. Employees of Company and the Company Subsidiaries are not
represented by any labor union nor are any collective bargaining agreements
otherwise in effect with respect to such employees.

         (o) Material Interests of Certain Persons. Except as set forth on
Schedule 2(o), to the best knowledge of Company, no officer or director of
Company or any Company Subsidiary, or any "associate" (as such term is defined
in Rule l4a-1 under the Exchange Act) of any such officer or director, has any
interest in any material contract or property (real or personal), tangible or
intangible, used in or pertaining to the business of Company or any Company
Subsidiary.

         Schedule 2(o) sets forth a correct and complete list of any loan from
Company or any Company Subsidiary to any present officer, director, employee or
any associate or related interest of any such person which was required under
Regulation O of the Federal Reserve Board to be approved by or reported to
Company's or such Company Subsidiary's Board of Directors.

         providing for insurance coverage of employees, workers' compensation,
         disability benefits, supplemental unemployment benefits, vacation
         benefits, retirement benefits, severance or termination of employment
         benefits, life, health, death, disability or accidental benefits.

                  (ii) Except as disclosed on Schedule 2(p)(ii), no Plan is a
         "multiemployer plan" within the meaning of Section 3(37) of ERISA.

                  (iii) Except as disclosed on Schedule 2(p)(iii), no Plan

         determination letter from the Internal Revenue Service stating that the
         Plan is tax qualified under Section 401(a) of the Code and Company
         knows of no reason that any such Plan is not qualified within the
         meaning of Section 401(a) of the Code and knows of no reason that each
         related Plan trust is not exempt from taxation under Section 501(a) of
         the Code.

                  (v) Except as disclosed on Schedule 2(p)(v), (a) all

         benefits vested and all benefits accrued under each Plan do not, in
         each case, exceed the assets of the Plan allocable to such vested or
         accrued benefits as of the end of the most recent Plan year.

                  (vi) Except as disclosed on Schedule 2(p)(vi) and to best
         knowledge of Company, no Plan or any trust created thereunder, nor any
         trustee, fiduciary or administrator thereof, has engaged in a
         "prohibited transaction," as such term is defined in Section 4975 of
         the Code or Section 406 of ERISA or violated any of the fiduciary
         standards under Part 4 of Title 1 of ERISA which could subject such
         Plan or trust, or any trustee, fiduciary or administrator thereof, or
         any party dealing with any such Plan or trust, to a tax penalty or
         prohibited transactions imposed by Section 4975 of the Code or would

         created thereunder has been terminated, nor have there been any
         "reportable events" as that term is defined in Section 4043 of ERISA,
         with respect to any Plan, other than those events which may result from
         the transactions contemplated by this Agreement and the Merger
         Agreement.

                  (viii) Except as disclosed on Schedule 2(p)(viii), neither the
         execution and delivery of this Agreement and the Merger Agreement nor
         the consummation of the transactions contemplated hereby and thereby
         will (a) result in any material payment (including, without limitation,
         severance, unemployment compensation, golden parachute or otherwise)
         becoming due to any director or employee or former employee of Company
         under any Plan or otherwise,

                                      -10-






         (b) materially increase any benefits otherwise payable under any Plan,
         or (c) result in the acceleration of the time of payment or vesting of
         any such benefits to any material extent.

(ii) the proxy statement included in the Registration Statement to be mailed to
Company's shareholders in connection with the meeting to be called to consider
the Merger and to Bank's shareholders in connection with the meeting to be
called to consider the Bank Merger (the "Proxy Statement") and (iii) any other
documents to be filed with the SEC or any regulatory authority in connection
with the transactions contemplated hereby, by the Merger Agreement, or by the
Bank Merger Agreement, will, at the respective times such Registration
Statement, Proxy Statement and other documents are filed with the SEC or any
regulatory authority and, in the case of the Registration Statement, when it
becomes effective and, with respect to the Proxy Statement, when mailed, and, in
the case of the Proxy Statement or any amendment thereof or supplement thereto,
at the time of the meeting of shareholders referred to in paragraph 4(c)(i), and
at the Effective Time of the Merger, contain any untrue statement of a material

any other regulatory authority in connection with the Merger and the Bank Merger
will comply as to form in all material respects with the provisions of
applicable law.

         (r) Registration Obligations. Except as set forth on Schedule 2(r),
neither Company nor any Company Subsidiary is under any obligation, contingent
or otherwise, by reason of any agreement to register any of its securities under
the Securities Act.

         (s) Brokers and Finders. Except for Keefe, Bruyette and Woods, Inc.,
neither Company nor any Company Subsidiary nor any of their respective officers,
directors or employees has employed any broker or finder or incurred any
liability for any financial advisory fees, brokerage fees, commissions or
finder's fees, and no broker or finder has acted directly or indirectly for
Company or any Company Subsidiary, in connection with this Agreement and the
Merger Agreement or the transactions contemplated hereby and thereby.

         (t) Fiduciary Activities. Company and each Company Subsidiary has
properly administered in all respects material and which could reasonably be
expected to be material, to the financial condition of Company and the Company
Subsidiaries taken as a whole all accounts for which it acts as a fiduciary,
including but not limited to accounts for which it serves as a trustee, agent,
custodian, personal representative, guardian, conservator or investment advisor,
in accordance with the terms of the governing documents and applicable state and
federal law and regulation and common law. Neither Company, any Company
Subsidiary, nor to the best knowledge of either of them, any director, officer
or

                                      -11-






employee of Company or any Company Subsidiary has committed any breach of
trust with respect to any such fiduciary account which is material to, or could

fiduciary account are true and correct in all material respects and accurately
reflect the assets of such fiduciary account.

(u) No Defaults. Neither Company nor any Company Subsidiary is in default, nor
has any event occurred that, with the passage of time or the giving of notice,

of its assets is bound or to which any of its assets is subject, the result of
which has had or could reasonably be expected to have a material adverse effect
upon Company and the Company Subsidiaries, taken as a whole. To the best of
Company's knowledge, all parties with whom Company or any Company Subsidiary has
material leases, agreements or contracts or who owe to Company or any Company
Subsidiary material obligations other than those arising in the ordinary course
of the banking business of the Company Subsidiaries are in compliance therewith
in all material respects.

         (v) Environmental Liability. There is no legal, administrative, or
other proceeding, claim, or action of any nature seeking to impose, or that
could result in the imposition of, on Company or any Company Subsidiary, any
liability relating to the release of hazardous substances as defined under any
local, state or federal environmental statute, regulation or ordinance
including, without limitation, the Comprehensive Environmental Response,
Compensation and Liability Act of 1980, as amended ("CERCLA"), pending or to the
best of Company's knowledge, threatened against Company or any Company
Subsidiary the result of which has had or could reasonably be expected to have a
material adverse effect upon Company and Company's Subsidiaries taken as a
whole; to the best of Company's knowledge, there is no reasonable basis for any
such proceeding, claim or action; and to the best of Company's knowledge neither
Company nor any Company Subsidiary is subject to any agreement, order, judgment,
or decree by or with any court, governmental authority or third party imposing
any such environmental liability. Company has provided Wells Fargo with copies
of all environmental assessments, reports, studies and other related information
in its possession with respect to each bank facility and each non-residential
OREO property.

to any pending action or proceeding, nor to Wells Fargo's knowledge is any such

assessment or collection of taxes, interest, penalties, assessments or
deficiencies that could reasonably be expected to have any material adverse
effect on Wells Fargo and its subsidiaries taken as a whole, and (ii) no issue
has been raised by any federal, state, local or foreign taxing authority in
connection with an audit or examination of the tax returns, business or

Fargo or any Wells Fargo Subsidiary which has had, or may reasonably be expected
to have, a material adverse effect on the business, financial condition or
results of operations of Wells Fargo and its subsidiaries taken as a whole.

         geographical area in which, or method by which, Wells Fargo or any
         Wells Fargo Subsidiary may carry on its business (other than as may be

         no reason that any such Wells Fargo Plan is not qualified within the
         meaning of Section 401(a) of the Code and knows of no reason that each

                  (i) Following the Effective Date of the Merger, Wells Fargo
         shall indemnify, defend and hold harmless any person who is now, or has
         been at any time prior to the date hereof, or who becomes prior to the
         Effective Time of the Merger, a director or officer of Company or any
         Company Subsidiary (an "Indemnified Party" and, collectively, the
         "Indemnified Parties"), to the same extent as Company is obligated to
         indemnify, defend and hold harmless the Indemnified Parties in
         Company's articles of incorporation or bylaws or similar governing
         documents of any Company Subsidiary, as applicable in the particular
         case and as in effect on the date hereof, with respect to claims
         arising from (A) facts or events that occurred before the Effective
         Time of the Merger, or (B) this Agreement or any of the transactions
         contemplated by this Agreement, whether in any case asserted or arising
         before or after the Effective Time of the Merger. Nothing contained in
         this paragraph 5(m)(i) shall be deemed to preclude the liquidation,
         consolidation, or merger of Company or any Company Subsidiary, in which
         case all of such rights to indemnification and limitations on liability
         shall be deemed to survive and continue as contractual rights
         notwithstanding any such liquidation or consolidation or merger;
         provided, however, that in the event of liquidation or sale of
         substantially all of the assets of Company, Wells Fargo shall
         guarantee, to the extent of the net asset value of Company or any
         Company

                                      -24-





         Subsidiary as of the Effective Date of the Merger, the indemnification
         obligations of Company or any Company Subsidiary to the extent of
         indemnification obligations of Company and the Company Subsidiaries
         described above. Notwithstanding anything to the contrary contained in
         this paragraph 5(m)(i), nothing contained herein shall require Wells
         Fargo to indemnify any person who was a director or officer of Company
         or any Company Subsidiary to a greater extent than Company or any
         Company Subsidiary is, as of the date of this Agreement, required to
         indemnify any such person;

                  (ii) any Indemnified Party wishing to claim indemnification
         under paragraph 5(m)(i), upon learning of any such claim, action, suit,
         proceeding, or investigation, shall promptly notify Wells Fargo
         thereof, but the failure to so notify shall not relieve Wells Fargo of
         any liability it may have to such Indemnified Party. In the event of
         any such claim, action, suit, proceeding, or investigation (whether
         arising before or after the Effective Time of the Merger) (A) Wells
         Fargo shall have the right to assume the defense thereof and Wells
         Fargo shall not be liable to any Indemnified Party for any legal
         expenses of other counsel or any other expenses subsequently incurred
         by such Indemnified Party in connection with the defense thereof,
         except that if Wells Fargo elects not to assume such defense or counsel
         for the Indemnified Party advises that there are issues which raise
         conflicts of interest between Wells Fargo and the Indemnified Party,
         the Indemnified Party may retain counsel satisfactory to them, and
         Wells Fargo shall pay the reasonable fees and expenses of such counsel
         for the Indemnified Party promptly as statements therefor are received,
         provided, however, that Wells Fargo shall be obligated pursuant to this
         subparagraph (ii) to pay for only one firm of counsel for all
         Indemnified Parties in any jurisdiction unless the use of one counsel
         for such Indemnified Parties would present such counsel with a conflict
         of interest, and (B) such Indemnified Party shall cooperate in the
         defense of any such matter;

                  (iii) for a period of six years after the Effective Time of
         the Merger, Wells Fargo shall use its best efforts to cause to be
         maintained in effect the current policies of directors' and officers'
         liability insurance maintained by Company (provided that Wells Fargo
         may substitute therefor policies of at least the same coverage and
         amount containing terms and conditions which are substantially no less
         advantageous) with respect to claims arising from facts or events which
         occurred before the Effective Time of the Merger; provided, however,
         that in no event shall Wells Fargo be obligated to expend, in order to
         maintain or provide insurance coverage pursuant to this paragraph
         5(m)(iii), any amount per annum in excess of 150% of the amount of the
         annual premiums paid as of the date hereof by Company for such
         insurance (the "Maximum Amount") and provided further that, prior to
         the Effective Time of the Merger, Company shall notify the appropriate
         directors' and officers' liability insurers of the Merger and of all
         pending or threatened claims, actions, suits, proceedings or
         investigations asserted or claimed against any Indemnified Party, or
         circumstances likely to give rise thereto to the extent known to the
         Company, in accordance with terms and conditions of the applicable
         policies. If the amount of the annual premiums necessary to maintain or
         procure such insurance coverage exceeds the Maximum Amount, Wells Fargo
         shall use reasonable efforts to maintain the most advantageous policies
         of directors' and officers' insurance obtainable for an annual premium
         equal to the Maximum Amount;

                  (iv) if Wells Fargo or any of its successors or assigns (A)
         shall consolidate with or merge into any other corporation or entity
         and shall not be the continuing or surviving corporation or entity of
         such consolidation or merger or (B) shall transfer all or substantially
         all

                                      -25-





         of its properties and assets to any individual, corporation or
         other entity, then and in each such case, proper provision shall be
         made so that the successors and assigns of Wells Fargo shall assume the
         obligations set forth in this paragraph 5(m); and

                  (v) the provisions of this paragraph 5(m) are intended to be
         for the benefit of, and shall be enforceable by, each Indemnified Party
         and his or her heirs and representatives.

         faith determine that a Takeover Proposal constitutes a Superior
         Proposal; provided, however, that Company shall not be permitted to
         terminate this Agreement pursuant to this paragraph 9(a)(iv) unless (i)
         it has not breached any covenant contained in paragraph 4(h) and (ii)
         it delivers to Wells Fargo simultaneously with such notice of
         termination the fee referred to in paragraph 9(c) below. As used in

         offer by a person to make a tender or exchange offer, or to engage in a

         substantially all of the assets of, Company, and (ii) "Superior
         Proposal" means a bona fide proposal or offer made by a person to

         on terms which the Board of Directors of Company shall determine in
         good faith, after taking into account the advice of counsel, to be more
         favorable to Company and its shareholders than the transactions
         contemplated hereby; or

                  (v) by Wells Fargo upon written notice to Company if (A) the
         Board of Directors of Company fails to recommend, withdraws, or
         modifies in a manner materially adverse to Wells Fargo, its approval or
         recommendation of this Agreement, or the transactions contemplated
         hereby, (B) after an agreement to engage in or the occurrence of an
         Acquisition Event (as defined below) or after a third party shall have
         made a proposal to Company or Company's shareholders to engage in an

         paragraph 4(c)(i), or (C) the meeting of Company shareholders
         contemplated by paragraph 4(c) is not held prior to March 15, 2001 and

         Company or any of the Company Subsidiaries representing 25% or more of
         the consolidated assets of Company and the Company Subsidiaries or
         (iii) a purchase or other acquisition (including by way of merger,
         consolidation, share exchange or any similar transaction) in one or a
         series of related transactions of beneficial ownership of securities
         representing 25% or more of the voting power of Company or the Bank in
         each case with or by a person or entity other than Wells Fargo or an
         affiliate of Wells Fargo.

         (b) Termination of this Agreement under this paragraph 9 shall not
release, or be construed as so releasing, either party hereto from any liability
or damage to the other party hereto arising out of the breaching party's willful
and material breach of the warranties and representations made by it, or willful
and material failure in performance of any of its covenants, agreements, duties
or obligations arising hereunder, and the obligations under paragraphs 4(g),
5(h) and 10 hereof shall survive such termination.

         shall have occurred; or

                  (ii) the Board of Directors of Company shall have authorized
         or approved an Acquisition Event or shall have publicly announced an
         intention to authorize or approve or shall have recommended that the
         shareholders of Company approve or accept any Acquisition Event,
