                                          [signature]

                                          James Stuart, Jr.
                                          Chairman and Chief Executive Officer

May  , 2000

 Please promptly complete, sign, date and return the enclosed proxy card
 whether or not you plan to attend the meeting. Failure to return a properly
 executed proxy or to vote at the meeting will have the same effect as a vote
 against the merger agreement and the merger. You may still vote at the
 meeting even if you have previously returned your proxy card.

                                  [FCBI logo]

  The board of directors of First Commerce Bancshares, Inc. has approved the
sale of First Commerce to Wells Fargo & Company. The sale will be accomplished
through the merger of a wholly-owned subsidiary of Wells Fargo with First
Commerce. The sale requires the approval of First Commerce's shareholders and
will be voted on at the special meeting. The time and place of the meeting are
set forth in the notice of special meeting that precedes this proxy statement-
prospectus.

  If the sale is completed, each share of First Commerce common stock will be
converted into the right to receive $35.95 in value of Wells Fargo common stock
based upon the average closing price of Wells Fargo common stock during a
twenty-day measurement period prior to the special meeting. If the total number
of shares of Wells Fargo common stock you will receive in the merger does not
equal a whole number, you will receive cash instead of the fractional share.

  On May  , 2000, Wells Fargo common stock closed at $  . No adjustment will be
made to the number of shares of Wells Fargo common stock to be issued to you to
reflect fluctuations in the price of Wells Fargo common stock occurring after
the special meeting.

  The merger is expected to be generally tax free to shareholders of First
Commerce, except for cash received instead of fractional shares.

  This document provides detailed information about the proposed sale. Please
read this entire document carefully. You can find additional information about
Wells Fargo and First Commerce from documents filed with the Securities and
Exchange Commission.

  Whether or not you plan to attend the meeting, please complete and mail the
enclosed proxy card. If you sign, date and mail your proxy card without
indicating how you want to vote, your proxy will be voted in favor of the sale.
If you fail to return your proxy card, or if you fail to instruct your broker
how to vote shares held for you in the broker's name, the effect will be the
same as a vote against the sale.

  The common stock of Wells Fargo is listed on the NYSE under the symbol "WFC,"
and the class A and class B common stock of First Commerce is listed on the
NASDAQ Small Cap Market under the symbols "FCBIA" and "FCBIB," respectively.

  Approval of the sale of First Commerce to Wells Fargo & Company requires the
affirmative vote of at least two-thirds of the outstanding shares of First
Commerce class A common stock and class B common stock, voting as separate
classes. No vote of Wells Fargo's stockholders is required to approve the
transaction.

[signature]
James Stuart, Jr.
Chairman of the Board and Chief Executive Officer

                     -------------------------------------

                   QUESTIONS AND ANSWERS ABOUT THIS DOCUMENT

What is the purpose of this proxy statement-prospectus?

  This document serves as both a proxy statement of First Commerce and a
prospectus of Wells Fargo. As a proxy statement, it's being provided to you by
First Commerce because the board of directors of First Commerce is soliciting
your proxy to vote to approve the proposed merger of First Commerce and Wells
Fargo. As a prospectus, it's being provided to you by Wells Fargo because Wells
Fargo is offering you shares of its common stock in exchange for your shares of
First Commerce common stock if the merger is completed.

Do I need to read the entire document?

  Absolutely. Parts of this document summarize information that is presented in
greater detail elsewhere in this document or in the appendices to this
document. Each summary discussion is qualified by reference to the full text.
For example, the summary of the terms of the merger agreement is qualified by
the actual terms of the merger agreement, a copy of which is included as
Appendix A.

Is there other information I should consider?

  Yes. Much of the business and financial information about Wells Fargo and
First Commerce that may be important to you is not included directly in this
document. Instead, this information is incorporated into this document by
references to documents separately filed by Wells Fargo and First Commerce with
the Securities and Exchange Commission. This means that Wells Fargo and First
Commerce may satisfy their disclosure obligations to you by referring you to
one or more documents separately filed by them with the SEC. See "Where You Can
Find More Information" on page 66 for a list of documents that Wells Fargo and
First Commerce have incorporated by reference into this proxy statement-
prospectus and for instructions on how to obtain copies of these documents. The
documents are available to you without charge.

What if there is a conflict between documents?

  You should rely on the most recently filed document. Information in this
proxy statement-prospectus may update information contained in the Wells Fargo
or First Commerce documents incorporated by reference. Similarly, information
in documents that Wells Fargo or First Commerce may file after the date of this
proxy statement-prospectus may update information contained in this proxy
statement-prospectus or information contained in previously filed documents.

What if I choose not to read the incorporated documents?

  Information contained in a document that is incorporated by reference is part
of this proxy statement-prospectus, unless it is superseded by information
contained directly in this proxy statement-prospectus or in documents filed
with the SEC after the date of this proxy statement-prospectus. Information
that is incorporated from another document is considered to have been disclosed
to you whether or not you choose to read the document.

The Merger (page 12)

  In the proposed transaction, a Wells Fargo subsidiary will merge with First
Commerce. First Commerce will survive the merger and become a subsidiary of
Wells Fargo. Wells Fargo will exchange shares of its common stock, par value $1
2/3 per share, for all of the outstanding First Commerce common stock, class A,
par value $0.20 per share, and First Commerce common stock, class B, par value
$0.20 per share. When used in this document, the term "First Commerce common
stock" refers to both classes of common stock collectively. After the merger is
completed, you will own shares of Wells Fargo common stock and Wells Fargo will
own all of the outstanding First Commerce common stock.

  The amended and restated agreement and plan of reorganization, which includes
the agreement and plan of merger as Exhibit A-1, is included in this document
as Appendix A. When used in this document, the term "merger agreement" refers
to the amended and restated agreement and plan of reorganization and the
agreement and plan of merger together. Please read the merger agreement, as it
is the document that governs the merger.

What You Will Receive In The Merger (page 30)

  If the merger is completed, each share of First Commerce common stock will be
converted into the right to receive $35.95 in value of Wells Fargo common stock
based upon the average closing price of Wells Fargo common stock during a
twenty-day measurement period prior to the special meeting. Since the price of
Wells

                                       1
<PAGE>

Fargo common stock will fluctuate after the special meeting and the completion
of the merger, First Commerce cannot assure you as to what the value of the
Wells Fargo common stock you receive in the merger will be following the
measurement period.

  Wells Fargo will not issue fractional shares in the merger. If the total
number of shares of Wells Fargo common stock you will receive in the merger
does not equal a whole number, you will receive cash instead of the fractional
share.

Merger Generally Tax Free To Shareholders of First Commerce (page 27)

  Shareholders of First Commerce generally will not recognize gain or loss for
U.S. federal income tax purposes from the exchange of their shares of First
Commerce common stock for shares of Wells Fargo common stock. Shareholders of
First Commerce will be taxed on cash they receive instead of fractional shares.

  The U.S. federal tax treatment described above may not apply to every
shareholder of First Commerce. In addition, this document does not address any
state, local or foreign tax laws that may apply to the merger. Determining the
tax consequences of the merger to you may be complicated. You should consult
your own advisor for a full understanding of the tax consequences of the
merger.

  First Commerce is not obligated to complete the merger unless it receives an
opinion of counsel that no gain or loss will be recognized for U.S. federal
income tax purposes by the holders of First Commerce common stock upon receipt
of Wells Fargo common stock except for cash received instead of fractional
shares.

First Commerce's Board Recommends Approval Of The Merger (page 13)

  First Commerce's board of directors believes that the merger is in the best
interests of First Commerce shareholders and recommends that First Commerce
shareholders approve the merger. First Commerce's board believes that the
merger will provide First Commerce shareholders with the potential for greater
stock value appreciation and liquidity than if First Commerce had remained
independent.

First Commerce's Financial Advisor Believes Merger Is Fair To First Commerce
Shareholders (page 14)

  Among other factors considered in deciding to approve the merger, the First
Commerce board of directors received the oral opinion of its financial advisor,
Merrill Lynch, Pierce, Fenner & Smith Incorporated that, as of January 28, 2000
(the date the First Commerce board voted on the merger) and updated through the
date of this document, the merger consideration was fair to the holders of
First Commerce common stock from a financial point of view. The opinion is
attached to this document as Appendix B. You should read this opinion
completely to understand the assumptions made, matters considered and
limitations of the review undertaken by Merrill Lynch in providing its opinion.

Additional Merger Benefits To First Commerce's Management (page 23)

  First Commerce's directors and executive officers have interests in the
merger that are different from yours.

  .  Bradley F. Korell, Stuart L. Bartruff, Mark W. Hansen and Jo E. Kinsey,
     all of whom are officers of First Commerce, have entered into agreements
     with Wells Fargo that provide for their employment after the merger.

  .  The merger agreement provides for rights to indemnification and
     continued insurance coverage for the benefit of directors and officers
     of First Commerce.

  The board of directors of First Commerce was aware of these additional
interests when it approved the merger agreement.

You Have No Dissenters' Rights (page 24)

  Under Nebraska law, you do not have dissenter's rights. See "Dissenters'
Rights."

Surrender Of Shares of First Commerce (page 24)

  To receive certificates for your shares of Wells Fargo common stock, you will
need to surrender your share certificates of First Commerce common stock. After
the merger is completed, Wells Fargo's stock transfer agent will send you
written instructions for exchanging your stock certificates. Please do not send
in your certificates until you receive these instructions.

First Commerce Special Meeting (page 9)

  First Commerce will hold its special meeting of shareholders at 2:00 p.m.,
Lincoln, Nebraska time, on the 11th floor of the NBC Center, 1248 O Street,
Lincoln, Nebraska. The purposes of the meeting are to:

  1. Vote on the merger agreement.

  2. Act on any other matters that may properly come before the meeting.

Record Date; Vote Required To Approve Merger (page 9)

  The record date for the special meeting is April 14, 2000. You can vote at
the meeting if you owned First Commerce common stock at the close of business
on that date. On the record date, there were 2,568,892 shares of First Commerce
class A common stock outstanding and entitled to vote and 10,775,394 shares of
First Commerce class B common stock outstanding and entitled to vote. You can
cast one vote for each share of First Commerce common stock that you owned on
the record date.

  Approval of the merger agreement requires the affirmative vote of two-thirds
of the outstanding shares of First Commerce class A common stock and class B
common stock, voting as separate classes. Not voting, or failing to instruct
your broker how to vote shares held for you in the broker's name, will have the
same effect as voting against the merger.

Some Directors and Officers Have Committed To Vote For The Merger (page 10)

  At the same time that the merger agreement was signed, Richard C. Schmoker,
William C. Schmoker, Kenneth W. Staab, John C. Osborne, John G. Lowe, III,
Connie Lapaseotes, David T. Calhoun and Scott Stuart, non-employee directors of
First Commerce; James Stuart, Jr., chairman and chief executive officer of
First Commerce; Brad Korell, president of National Bank of Commerce Trust &
Savings Association; Stuart L. Bartruff, executive vice president and secretary
of First Commerce; James Stuart III, Chairman and CEO of First Commerce
Investors, Inc.; and Mark Hansen, executive vice president of First Commerce,
entered into individual support agreements with Wells Fargo. Under their
support agreements, these individuals have agreed, among other things, to vote
in favor of the merger all shares of First Commerce common stock beneficially
owned by them at the record date for the meeting.

  At the record date for the meeting, these individuals beneficially owned a
total of 1,564,866 shares of First Commerce class A common stock and 5,982,421
shares of First Commerce class B common stock, respectively. These shares
represent approximately 60.9% of the shares of First Commerce class A common
stock and approximately 55.5% of the shares of First Commerce class B common
stock entitled to vote at the meeting.

We Must Obtain Regulatory Approvals to Complete the Merger (page 25)

  The Board of Governors of the Federal Reserve System must approve the merger
before it can be completed. Wells Fargo filed an application with the Federal
Reserve Board on March 30, 2000. As of the date of this document, the Federal
Reserve Board had not acted on Wells Fargo's application for approval of the
merger. Although Wells Fargo expects that the Federal Reserve Board will
approve the merger, it cannot be certain when or if, or on what terms and
conditions, the required approval will be given. It is anticipated that a
modest level of divestitures may be required in connection with obtaining
Federal Reserve Board approval of the merger.

  Approval of the Merger must also be obtained from the Colorado State Bank
Commissioner.

Other Conditions To Completing The Merger (page 35)

  In addition to the receipt of the approval of the Federal Reserve Board and
the Colorado State Bank Commissioner, there are a number of other conditions
that must be met before the merger can be completed. These conditions include:

  .  approval of the merger agreement by the holders of First Commerce class
     A common stock and class B common stock, voting as separate classes;

  .  receipt by First Commerce of an opinion of counsel concerning the tax
     consequences of the merger;

                                       4
<PAGE>


  .  authorization for listing on the New York and Chicago Stock Exchanges of
     the shares of Wells Fargo common stock to be issued in the merger to
     First Commerce shareholders;

  .  receipt of all necessary governmental approvals, and the absence of an
     order of any court or governmental authority prohibiting the merger; and

  .  material compliance by each party with the terms and provisions of the
     merger agreement.

  Wells Fargo or First Commerce may waive a condition it is entitled to assert
so long as the law does not require the condition to be met.

Termination Of The Merger Agreement (page 36)

  Wells Fargo and First Commerce can agree to terminate the merger agreement at
any time without completing the merger. Also, either company can terminate the
merger agreement without the consent of the other under the following
circumstances:

  .  a court or other governmental authority prohibits the merger;

  .  the merger is not completed by October 31, 2000, unless the failure to
     complete the merger on or before that date is the fault of the company
     seeking to terminate; or

  .  a governmental authority issues a final and nonappealable order
     permanently prohibiting the merger.

Your Rights Will Differ As A Wells Fargo Stockholder (page 51)

  Your rights as a First Commerce shareholder are currently governed by
Nebraska law and First Commerce's articles of incorporation and bylaws. Upon
completion of the merger, you will become a Wells Fargo stockholder, and your
rights will be governed by Delaware law and Wells Fargo's restated certificate
of incorporation and bylaws.

Wells Fargo Expects To Use Purchase Accounting (page 29)

  Wells Fargo expects to account for the merger under the purchase method of
accounting. Wells Fargo will record, at fair value, the acquired assets and
assumed liabilities of First Commerce. To the extent the total purchase price
exceeds the fair value of the assets acquired and liabilities assumed, Wells
Fargo will record goodwill.

Financial Modernization Will Increase Competition (page 37)

  Bank holding companies that elect to become financial holding companies may
affiliate with securities firms and insurance companies and engage in other
activities that are financial in nature. "Financial in nature" includes:

  .  securities underwriting, dealing and market making;

  .  sponsoring mutual funds and investment companies;

  .  insurance underwriting and agency;

  .  merchant banking activities; and

  .  activities that the Federal Reserve Board has determined to be closely
     related to banking.

                                       5
<PAGE>


  Wells Fargo has elected to become a financial holding company. Securities
firms and insurance companies that elect to become financial holding companies
may acquire banks and other financial institutions. This may significantly
change the competitive environment in which Wells Fargo and its subsidiaries
conduct business.

Forward-Looking Statements May Prove Inaccurate (page 69)

Commerce. There are a number of factors that may cause actual conditions,

Comparative Per Common Share Data

  The following table shows comparative per share data for Wells Fargo common
stock on a historical and pro forma combined basis and for First Commerce
common stock on a historical and pro forma equivalent basis. The information in
the table assumes that Wells Fargo will account for the merger using the
purchase method of accounting. The pro forma equivalent information for First
Commerce is calculated by multiplying the pro forma basic and diluted earnings
per share, the historical cash dividends declared per share of Wells Fargo
common stock and the pro forma book value per share by the assumed exchange
ratio of 0.883119. This information reflects the fact that you will receive a
fraction of a share of Wells Fargo common stock for each First Commerce share
you hold. The assumed exchange ratio of 0.883119 is based on a hypothetical
average closing price of Wells Fargo common stock of $40.708, which is the
average closing price of Wells Fargo common stock for the twenty trading days
ending April 14, 2000. The actual exchange ratio will be determined during the
20-trading-day period ending on the date preceding the special meeting. See
"The Merger--Effect Of The Merger."

  You should read the data with the historical financial statements and related
notes of Wells Fargo and First Commerce. Wells Fargo's and First Commerce's
historical financial statements are included in documents filed with the SEC.

                         FIRST COMMERCE SPECIAL MEETING

  The board of directors of First Commerce is soliciting proxies from the
holders of First Commerce class A and class B common stock for use at the
special meeting of First Commerce shareholders and at any adjournments of the
meeting. When used in this document, the term "First Commerce common stock"
refers to both classes of common stock collectively. This document, together
with the form of proxy, is expected to be mailed to holders of First Commerce
common stock on or about May  , 2000.

Time And Place Of The Meeting

  The time and place of the special meeting of First Commerce shareholders are:

    [Friday], June [9], 2000
    2:00 p.m., Lincoln, Nebraska time
    NBC Center, 11th floor
    1248 O Street
    Lincoln, Nebraska 68508-2095

Matters To Be Considered At The Meeting

  The special meeting of First Commerce shareholders will be held to:

  1. Vote on a proposal to approve the amended and restated agreement and
     plan of reorganization, entered into as of the 1st day of February,
     2000, and amended and restated as of April 14, 2000, but effective as of
     February 1, 2000, by and among First Commerce, Wells Fargo, First
     National Bank and Trust Co. of Kearney, The Overland National Bank of
     Grand Island, Western Nebraska National Bank and The First National Bank
     of West Point; and a related agreement and plan of merger, dated as of
          , 2000, by and between First Commerce and Wells FCBI Merger Co., a
     wholly-owned subsidiary of Wells Fargo. The agreement and plan of
     reorganization, which includes the agreement and plan of merger as
     Exhibit A-1, is included in this proxy statement-prospectus as Appendix
     A. When used in this document, the term "merger agreement" refers to the
     agreement and plan of reorganization and the agreement and plan of
     merger together. The merger agreement provides for the merger of a
     wholly-owned subsidiary of Wells Fargo with and into First Commerce upon
     the terms and subject to the conditions set forth in the merger
     agreement. See "The Merger Agreement."

  2. Act on any other matters that may properly come before the meeting.

Record Date

  First Commerce's board of directors has established April 14, 2000 as the
record date for the meeting. Only holders of record of First Commerce common
stock on that date are entitled to attend and vote at the meeting or at any
adjournment of the meeting.

Outstanding Shares

  On April 14, 2000, there were 2,568,892 shares of First Commerce class A
common stock outstanding and 10,775,394 shares of class B common stock
outstanding. Each outstanding share of First Commerce common stock is entitled
to one vote.

Quorum

  A quorum consisting of the holders of a majority of the shares of First
Commerce common stock outstanding at the record date must be present in person
or represented by proxy for the transaction of business

                                       9
<PAGE>

at the special meeting. Shares of First Commerce common stock present in person
at the meeting that are not voted, and shares of First Commerce common stock
for which proxies have been received but that abstain from voting, are counted
in determining whether a quorum is present. Shares held in street name that
have been designated by brokers on proxy cards as not voted will be counted for
purposes of determining whether a quorum exists.

Vote Required

  Approval of the merger agreement and the merger requires the affirmative vote
of two-thirds of the First Commerce class A common stock and two-thirds of the
class B common stock, voting as separate classes. Because approval of the
merger requires the affirmative vote of a specified percentage of outstanding
shares, not voting on the proposal, or failing to instruct your broker how to
vote shares held for you by the broker, will have the same effect as voting
against the proposal.

Share Ownership

  First Commerce. The Stuart family controls a total of 1,559,232 shares of
First Commerce class A common stock and 5,904,461 of the class B common stock,
representing approximately 60.7% and 54.8% of the shares of class A and class B
common stock entitled to vote at the special meeting, respectively. The
Catherine Stuart Schmoker Family Partnership, The James Stuart, Jr. Family
Partnership and The Scott Stuart Family Partnership share in the investment

virtue of being partners in The Catherine Stuart Schmoker Family Partnership.
James Stuart, Jr. individually and as custodian, Susan S. Stuart individually,

class B common stock entitled to vote at the special meeting, respectively.
Each of these directors and officers is expected to vote the First Commerce
common stock beneficially owned by him in favor of the merger. In addition, the

Merger."

Wells Fargo's directors and executive officers as a group beneficially owned a
total of     shares of First Commerce class A common stock and     shares of

<PAGE>

Korell, president of National Bank of Commerce Trust & Savings Association;
Stuart L. Bartruff, executive vice president and secretary of First Commerce;
James Stuart III, Chairman and CEO of First Commerce Investors, Inc.; and Mark
Hansen, executive vice president of First Commerce, entered into agreements

class B common stock, representing approximately 60.9% and 55.5% of the shares

respectively.

Voting And Revocation Of Proxies

  All shares of First Commerce common stock represented at the special meeting
by a properly executed proxy will be voted in accordance with the instructions
indicated on the proxy, unless the proxy is revoked before a vote is taken. If
you sign and return a proxy without voting instructions, and do not revoke the
proxy, the proxy will be voted "FOR" the proposal to approve the merger
agreement and the merger, and "FOR" any other matters that may properly come
before the meeting. You may revoke your proxy at any time before it is voted.

  Votes cast by proxy or in person at the special meeting will be tabulated by
the election inspectors appointed for the meeting and will determine whether or
not a quorum is present. The election inspectors will treat abstentions as
shares that are present and entitled to vote for purposes of determining the
presence of a quorum, but as unvoted for purposes of determining the approval
of any matter submitted to the shareholders for a vote. If a broker indicates
on the proxy that it does not have discretionary authority as to certain shares
to vote on a particular matter, those shares will not be considered as present
and entitled to vote with respect to that matter.

Solicitation Of Proxies

  In addition to solicitation by mail, directors, officers and employees of
First Commerce and its subsidiaries may solicit proxies from First Commerce
shareholders, either personally or by telephone or other form of communication.
None of the foregoing persons who solicit proxies will be specifically
compensated for such services. First Commerce does not anticipate that any
other persons will be specifically engaged to solicit proxies or that special
compensation will be paid for that purpose, but First Commerce reserves the
right to do so should it conclude that such efforts are necessary or advisable.

  Nominees, fiduciaries and other custodians will be requested to forward
soliciting materials to beneficial owners and will be reimbursed for their
reasonable expenses incurred in sending proxy material to beneficial owners.
First Commerce will bear its own expenses in connection with any solicitation
of proxies for the special meeting.

Other Matters Considered At The Meeting

  If an insufficient number of votes for the merger is received before the
scheduled meeting date, Wells Fargo and First Commerce may decide to postpone
or adjourn the special meeting. If this happens, proxies that have been
received that either have been voted for the merger or contain no instructions
will be voted for adjournment.

  First Commerce's board of directors is not aware of any business to be
brought before the special meeting other than the proposal to approve the
merger. If other matters are properly brought before the special meeting or any
adjournments or postponements of the meeting, the persons appointed as proxies
will have authority to vote the shares represented by properly executed proxies
in accordance with their discretion and judgment as to the best interests of
First Commerce.

                                   THE MERGER

  This summary of the material terms and provisions of the merger agreement is
qualified in its entirety by reference to the merger agreement, which is
attached as Appendix A to this document and is incorporated into this summary
by reference.

Effect Of The Merger

  The First Commerce board and the Wells Fargo board have each unanimously
approved the merger agreement, which provides for the merger of a wholly-owned
subsidiary of Wells Fargo into First Commerce at the time the merger becomes
effective, with First Commerce surviving as a wholly-owned subsidiary of Wells
Fargo. As a result of the merger:

  .  Wells Fargo will exchange shares of its common stock for shares of First
     Commerce common stock.

  .  Wells Fargo will acquire all of the outstanding common stock of First
     Commerce, resulting in First Commerce becoming a wholly-owned subsidiary
     of Wells Fargo.

  .  First Commerce shareholders will become Wells Fargo stockholders, with
     their rights governed by Delaware law and Wells Fargo's restated
     certificate of incorporation and bylaws. See "Comparison Of
     Shareholder/Stockholder Rights."

  At the completion of the merger, each outstanding share of First Commerce
class A common stock, with a par value of $0.20 per share, and each outstanding
share of First Commerce class B common stock, with a par value of $0.20 per
share, will be converted into the right to receive the number of shares of
Wells Fargo common stock, with a par value of $1 2/3 per share, determined by
dividing $35.95 by the Wells Fargo Measurement Price. When used in this
document, this number is referred to as the "exchange ratio." The "Wells Fargo
Measurement Price" is defined as the average of the closing prices of a share
of Wells Fargo common stock as reported on the consolidated tape of the New
York Stock Exchange during the measurement period of 20 trading days ending on
June [8], 2000, the day immediately preceding the special meeting. Since the
price of Wells Fargo common stock will fluctuate after the special meeting and
the completion of the merger, First Commerce cannot assure you as to what the
value of the Wells Fargo common stock you receive in the merger will be
following the measurement period used to determine the Wells Fargo Measurement
Price.

  When used in this document, a "share" of Wells Fargo common stock in this
document generally refers to that share together with one Series C Junior
Participating Preferred Stock Purchase Right issued to Wells Fargo stockholders
under a rights agreement, dated as of October 21, 1998, between Wells Fargo and
ChaseMellon Shareholder Services, L.L.C., as rights agent. When you surrender
your shares of First Commerce common stock in exchange for Wells Fargo common
stock after the merger is completed, each share of Wells Fargo common stock you
receive in exchange will include one Wells Fargo stockholder right. The Wells
Fargo stockholder rights are described in more detail under "Wells Fargo
Capital Stock--Wells Fargo Rights Plan."

Background Of And Reasons For The Merger

 Background of the Merger

  On several occasions over a number of years, representatives of Norwest
Corporation (now Wells Fargo) informally contacted representatives of First
Commerce regarding a possible merger or acquisition. In June 1999, James Stuart
Sr., advisor to the First Commerce board of directors, and Richard C. Schmoker,
a director of First Commerce, met with representatives of Wells Fargo (Richard
Kovacevich and James Campbell) for exploratory discussions regarding a possible
transaction.

  During this time, the management of First Commerce discussed from time to
time the various options open to First Commerce, in light of the changing
banking environment, including the potential enactment of financial
modernization legislation by the Congress of the United States. Also during
this period, First Commerce entered

                                       12
<PAGE>

into a confidentiality agreement with Wells Fargo and provided Wells Fargo with
information concerning First Commerce.

  In September 1999, First Commerce retained Merrill Lynch to assist it in a
strategic review of its business and to help it evaluate strategic
alternatives. Merrill Lynch was authorized to contact Wells Fargo, and later
other selected parties, that might potentially be interested in a transaction
with First Commerce.

  During the period September through December 1999, representatives of First
Commerce held a series of discussions and communications with representatives
of Wells Fargo concerning the terms of a possible business combination. At the
regular monthly meeting of the board of directors of First Commerce held on
December 21, 1999, James Stuart, Jr., the Chairman and Chief Executive Officer
of First Commerce, briefed the directors on the background and status of the
discussions, including the work of Merrill Lynch and the status of exploration
of a possible transaction. Following the December board meeting and continuing
into January of 2000, representatives of Wells Fargo conducted due diligence
investigations of First Commerce.

  Beginning in mid-January 2000, legal counsel to each company began to
negotiate the terms of the definitive documentation with respect to a possible
merger between the two companies, including drafts of a merger agreement and
related agreements, shareholder support agreements, and employment agreements
and non-competition agreements for certain of First Commerce's executives.

  During this period, representatives of First Commerce conducted a due
diligence investigation of Wells Fargo. At the regular monthly meeting of the
First Commerce board of directors held on January 25, 2000, the board was fully
briefed on the status of the potential merger. On January 27, 2000, First
Commerce issued a press release indicating that it was in negotiations with
Wells Fargo.

  On January 28, 2000, the First Commerce board met to discuss the terms of the
proposed merger. Merrill Lynch outlined the proposed transaction with Wells
Fargo, and discussed its financial terms. During this meeting, the First
Commerce board received the oral opinion of Merrill Lynch, subsequently
confirmed by a written opinion dated January 28, 2000, that, as of that date,
and subject to certain matters stated therein, the exchange ratio set forth in
the merger agreement was fair, from a financial point of view, to the holders
of First Commerce class A and class B common stock. First Commerce's legal
counsel, Wachtell, Lipton, Rosen & Katz and Cline, Williams, Wright, Johnson &
Oldfather, reviewed the terms of the merger agreement and related agreements,
the shareholder support agreements, and the employment and non-competition
agreements, and other relevant legal issues, including a discussion of various
drafting points in the documents that were subject to being finalized with
Wells Fargo. After further discussion of these matters, the First Commerce
board unanimously determined that the merger was fair to, and in the best
interests of, First Commerce and its shareholders, approved the merger and the
merger agreement and related agreements, subject to the resolution of the
unresolved issues, resolved to submit the merger agreement to First Commerce
shareholders for their approval, and authorized senior management to take such
action as was needed to finalize the documents and, if satisfactorily
finalized, to execute the documents and to effectuate the transactions
contemplated in them.

  During the weekend of January 29 and 30, and continuing on Monday, January
31, 2000, representatives of First Commerce and Wells Fargo resolved the
remaining drafting issues. On the afternoon of February 1, 2000, the merger
agreement and related documents were signed by First Commerce and Wells Fargo
and on February 2, 2000, First Commerce and Wells Fargo issued a joint press
release announcing the proposed merger.

 First Commerce's Board of Directors' Reasons for the Merger

  The First Commerce board believes that the proposed merger with Wells Fargo
is in the best interests of First Commerce and its shareholders. In making its
determination, the board considered a number of factors, including the
following:

  .  the consideration First Commerce shareholders will receive if the merger
     is effected and the likelihood that it will deliver greater value to
     First Commerce shareholders than that expected if First Commerce
     remained independent;

                                       13
<PAGE>

  .  the board's consideration of Merrill Lynch's January 28, 2000
     presentation, including Merrill Lynch's opinion that the exchange ratio
     was fair to First Commerce shareholders from a financial point of view
     as of that date;

  .  the complementary nature of First Commerce's business, services and
     products with Wells Fargo's, and the opportunity to create a combined
     business that offers a wider variety of services to First Commerce's
     clients and enhances the ability to attract new clients;

  .  the historical performance of Wells Fargo's common stock and Wells
     Fargo's historical financial performance;

  .  the board's review of other strategic alternatives potentially available
     to First Commerce;

  .  the opinion of First Commerce's advisors that the merger will be
     accomplished on a tax-free basis for First Commerce shareholders for
     U.S. federal income tax purposes (except for cash received instead of
     fractional shares);

  .  the likelihood of a smooth integration of First Commerce's business with
     that of Wells Fargo;

  .  retention arrangements with key employees of First Commerce in
     connection with the merger;

  .  the terms and conditions of the merger agreement;

  .  the judgment and advice of First Commerce's senior management; and

  .  the board's conclusion that the merger would provide First Commerce
     shareholders with an opportunity for continued equity participation in a
     larger enterprise, and with greater liquidity.

Opinion Of First Commerce's Financial Advisor

  First Commerce retained Merrill Lynch to act as its financial advisor in
connection with the merger. On January 28, 2000, the board of directors of
First Commerce held a meeting to evaluate the proposed merger. At this meeting,
Merrill Lynch rendered its oral opinion that, as of that date and based upon
and subject to the factors and assumptions set forth in its opinion, the merger
consideration was fair, from a financial point of view, to the First Commerce
shareholders. [Merrill Lynch subsequently confirmed and updated its oral
opinion in writing by delivering to the board of directors of First Commerce a
written opinion dated as of the date of this document. In connection with its
written opinion dated as of the date of this document, Merrill Lynch confirmed
the appropriateness of its reliance on the analyses used to render its earlier
opinion. It also performed procedures to update certain of its analyses and
reviewed the assumptions used in its analyses and the factors considered in
connection with its earlier opinion.]

  The full text of the Merrill Lynch opinion which describes, among other
things, the assumptions made, matters considered, and qualifications and
limitations on the review undertaken by Merrill Lynch is attached as Appendix B
to this document and is incorporated in this document by reference. First
Commerce shareholders should read Merrill Lynch's opinion carefully and in its
entirety.

  Merrill Lynch's opinion is directed to the board of directors of First
Commerce and addresses only the fairness, from a financial point of view, of
the merger consideration to the First Commerce shareholders. The opinion does
not address any other aspect of the merger or any related transaction, nor does
it constitute a recommendation to any shareholder as to how to vote at the
First Commerce special meeting. The summary of the fairness opinion set forth
in this document is qualified in its entirety by reference to the full text of
the opinion.

                                       14
<PAGE>

   In arriving at its opinion, Merrill Lynch, among other things:

  .  reviewed certain publicly available business and financial information
     relating to First Commerce and Wells Fargo that Merrill Lynch deemed to
     be relevant;

  .  reviewed certain information, including financial forecasts, relating to
     the businesses, earnings, assets, liabilities and prospects of First
     Commerce furnished to Merrill Lynch by the senior management of First
     Commerce;

  .  conducted discussions with members of senior management and
     representatives of First Commerce and Wells Fargo concerning the matters
     described in the bullet points set forth above, as well as their
     respective businesses and prospects before and after giving effect to
     the merger;

  .  reviewed the market prices and valuation multiples for First Commerce
     common stock and Wells Fargo common stock and compared them with those
     of publicly traded companies that Merrill Lynch deemed to be relevant;

  .  reviewed the respective publicly reported financial condition and
     results of operations of First Commerce and Wells Fargo and compared
     them with those of publicly traded companies that Merrill Lynch deemed
     to be relevant;

  .  compared the proposed financial terms of the merger with the financial
     terms of other transactions that Merrill Lynch deemed to be relevant;

  .  participated in discussions and negotiations with representatives of
     First Commerce and Wells Fargo and their financial and legal advisors
     with respect to the merger;

  .  reviewed the merger agreement; and

  .  reviewed such other financial studies and analyses and took into account
     such other matters as Merrill Lynch deemed necessary, including Merrill
     Lynch's assessment of general economic, market and monetary conditions.

  In rendering its opinion, Merrill Lynch assumed and relied on the accuracy
and completeness of all information supplied or otherwise made available to
Merrill Lynch, or that was discussed with, or reviewed by or for Merrill Lynch,
or that was publicly available, and Merrill Lynch did not assume any
responsibility for independently verifying this information or undertake an
independent evaluation or appraisal of the assets or liabilities of First
Commerce or Wells Fargo nor has Merrill Lynch been furnished any such
evaluation or appraisal.

  Merrill Lynch is not an expert in the evaluation of allowances for loan
losses, and neither made an independent evaluation of the adequacy of the
allowances for loan losses of First Commerce or Wells Fargo, nor reviewed any
individual credit files of First Commerce or Wells Fargo or been requested to
conduct such a review and, as a result, Merrill Lynch has assumed that the
aggregate allowances for loan losses for both First Commerce and Wells Fargo
are adequate to cover such losses and will be adequate on a pro forma basis for
the combined company. In addition, Merrill Lynch did not assume any obligation
to conduct, nor did Merrill Lynch conduct, any physical inspection of the
properties or facilities of First Commerce or Wells Fargo. With respect to the
financial and operating forecast information furnished to or discussed with
Merrill Lynch by First Commerce and Wells Fargo, including, without limitation,
financial forecasts, valuations of contingencies and projections regarding
under-performing and non-performing assets, net charge-offs, adequacy of
reserves and future economic conditions, Merrill Lynch assumed that the
information was reasonably prepared and reflected the best currently available
estimates and judgments of the senior management of each of First Commerce and
Wells Fargo as to the future financial and operating performance of First
Commerce, Wells Fargo or the combined entity, as the case may be. Merrill
Lynch's opinion is necessarily based upon market, economic and other conditions
as in effect on, and on the information made available to Merrill Lynch as of,
the date of its opinion.

                                       15
<PAGE>

  For purposes of rendering its opinion Merrill Lynch assumed that, in all
respects material to its analyses:

  .  the merger will be completed substantially in accordance with the terms
     set forth in the merger agreement;

  .  the representations and warranties of each party in the merger agreement
     and in all related documents and instruments referred to in the merger
     agreement are true and correct;

  .  each party to the merger agreement and all related documents will
     perform all of the covenants and agreements required to be performed by
     the party under these documents;

  .  all conditions to the completion of the merger will be satisfied without
     any waivers; and

  .  in the course of obtaining the necessary regulatory, contractual, or
     other consents or approvals for the merger, no restrictions, including
     any divestiture requirements, termination or other payments or
     amendments or modifications, will be imposed that will have a material
     adverse effect on the future results of operations or financial
     condition of the combined entity or the contemplated benefits of the
     merger.

  Merrill Lynch's opinion is not an expression of an opinion as to the prices
at which shares of First Commerce common stock or shares of Wells Fargo common
stock will trade following the announcement of the merger or the actual value
of the shares of common stock of Wells Fargo when issued pursuant to the
merger, or the prices at which the shares of common stock of Wells Fargo will
trade following the completion of the merger.

 Analyses of Merrill Lynch

  In performing its analyses, Merrill Lynch made numerous assumptions with
respect to industry performance, general business, economic, market and
financial conditions and other matters, many of which are beyond the control of
Merrill Lynch, First Commerce and Wells Fargo. Any estimates contained in the
analyses performed by Merrill Lynch are not necessarily indicative of actual
values or future results, which may be significantly more or less favorable
than suggested by these analyses. Additionally, estimates of the value of
businesses or securities do not purport to be appraisals or to reflect the
prices at which such businesses or securities might actually be sold.
Accordingly, these analyses and estimates are inherently subject to substantial
uncertainty. In addition, the Merrill Lynch opinion was among several factors
taken into consideration by the board of directors of First Commerce in making
its determination to approve the merger agreement and the merger. Consequently,
the analyses described below should not be viewed as determinative of the
decision of the board of directors of First Commerce or management of First
Commerce with respect to the fairness of the merger consideration.

  The following is a summary of the material financial analyses presented by
Merrill Lynch to the board of directors of First Commerce on January 28, 2000
in connection with the rendering of its oral opinion on that date. The summary
is not a complete description of the analyses underlying the Merrill Lynch
opinion or the presentation made by Merrill Lynch to the board of directors of
First Commerce, but summarizes the material analyses performed and presented in
connection with its opinion. The preparation of a fairness opinion is a complex
analytic process involving various determinations as to the most appropriate
and relevant methods of financial analysis and the application of those methods
to the particular circumstances. Therefore, a fairness opinion is not readily
susceptible to partial analysis or summary description.

  In arriving at its opinion, Merrill Lynch did not attribute any particular
weight to any analysis or factor that it considered, but rather made
qualitative judgments as to the significance and relevance of each analysis and
factor. The financial analyses summarized below include information presented
in tabular format. Accordingly, Merrill Lynch believes that its analyses and
the summary of its analyses must be considered as a whole and that selecting
portions of its analyses and factors or focusing on the information presented
below in tabular format, without considering all analyses and factors or the
full narrative description of the financial

                                       16
<PAGE>

analyses, including the methodologies and assumptions underlying the analyses,
could create a misleading or incomplete view of the process underlying its
analyses and opinion. The tables alone do not constitute a complete description
of the financial analyses.

  Calculation of Implied Value of the Merger Consideration. Merrill Lynch
reviewed the terms of the merger. It noted that the transaction had a fixed
aggregate value of $479.5 million with a floating exchange ratio, which implied
a fixed value of approximately $35.95 per share of First Commerce class A
common stock and class B common stock. Merrill Lynch also noted that the fixed
aggregate value of the transaction represented a 74% premium to First
Commerce's aggregate market value on the date 30 trading days preceding January
28, 2000, and also represented a 67% premium to the per share market price of
First Commerce class A common stock and 75% premium to the per share market
price of First Commerce class B common stock on the date 30 trading days
preceding January 28, 2000.

  Transaction Pricing Multiple Analysis. Merrill Lynch performed a transaction
pricing multiple analysis of the transaction offer value in the merger. Core
earnings is comprised of total earnings excluding securities gains generated by
First Commerce's "Global Fund." The Global Fund is a portfolio of primarily
equity securities traded for the account of First Commerce. Merrill Lynch based
its analysis on a floating exchange ratio, a transaction value per First
Commerce share of $35.95, and an aggregate offer value of $479.5 million.
Merrill Lynch determined that:

  .  the transaction value as a multiple of book value (based on financial
     data for the period ending December 31, 1999) was 1.86x;

  .  the transaction value as a multiple of tangible book value (based on
     financial data for the period ending December 31, 1999) was 1.92x;

  .  the transaction value as a multiple of 1999 core earnings was 17.09x;

  .  the transaction value as a multiple of 2000 estimated management core
     earnings per share was 16.21x; and

  .  the tangible book premium paid as a percentage of First Commerce's
     deposits (based on financial data for the period ending December 31,
     1999) was 12.67%.

  Merrill Lynch further analyzed publicly available financial and stock market
information for First Commerce and for selected bank merger and acquisition
transactions involving commercial bank targets in Nebraska, Kansas, Oklahoma,
South Dakota, North Dakota, Missouri, Iowa and Arkansas to determine the
transaction values of such transactions as a premium to the per share price of
the common stock of the targets involved in such transactions at different
times. The selected comparable transactions were those completed since 1997 and
involved total consideration that ranged from $100 million to $1 billion. The
following table compares the transaction values of the comparable transactions
as a premium to the per share price of the common stock of the targets involved
in these transactions at different times. For purposes of the table, the 52-
week high of First Commerce common stock (class A and class B) was reached on
January 20, 2000, and the figures in the column designated the "Price 30
Trading Days Prior" represents, for the merger, 30 trading days prior to
Merrill Lynch's presentation to the First Commerce Board, and, for each of the
selected comparable transactions, 30 trading days prior to the announcement of
such transactions:

  Discounted Dividend Analysis--First Commerce. Merrill Lynch performed a
discounted dividend analysis to estimate a range of present values per share of
First Commerce common stock assuming First Commerce continued to operate as a
stand-alone entity. This range was determined by adding (1) the present value
of the estimated future dividend stream that First Commerce could generate
through 2004, and (2) the present value at December 31, 1999 of the "terminal
value" of First Commerce common stock at the end of this period.

  In calculating a terminal value of First Commerce common stock, Merrill Lynch
applied multiples of 10.0x, 11.0x and 12.0x to year 2005 forecasted cash
earnings. The dividend stream and terminal value were then discounted back to
December 31, 1999 using discount rates of 12.0%, 13.0% and 14.0%, which rates
Merrill Lynch viewed as within the appropriate range for a company with First
Commerce's risk characteristics.

  In performing this analysis, Merrill Lynch used management's earnings
estimates for 2000. For periods after 2000, earnings were assumed to increase
at First Commerce management's projected annual long-term earnings growth rate
of 7.5% since there were no long term "street" estimates published for First
Commerce by recognized data services that monitor and publish compilations of
earnings estimates by selected research analysts of interest to institutional
investors. Merrill Lynch also assumed an annual asset growth rate of 5%, and
further assumed that earnings in excess of those necessary to maintain First
Commerce's tangible common equity ratio at its then-current value of 9.6% could
be paid out as dividends. Based on the above assumptions, Merrill Lynch
determined that the stand-alone present value of the First Commerce common
stock ranged from $20.92 to $26.10 per share, and that the aggregate company
valuation ranged from $279 million to $348 million.

  Discounted Dividend Analysis--Wells Fargo. Merrill Lynch also performed a
discounted dividend analysis to estimate a range of present values per share of
Wells Fargo common stock assuming Wells Fargo continued to operate as a stand-
alone entity. As with the analysis performed with regard to First Commerce,
this range was determined by adding (1) the present value of the estimated
future dividend stream that Wells Fargo could generate through 2004, and (2)
the present value at December 31, 1999 of the "terminal value" of Wells Fargo
common stock at the end of this period.

  In calculating a terminal value of Wells Fargo common stock, Merrill Lynch
applied multiples of 12.0x, 13.0x and 14.0x to year 2005 forecasted cash
earnings. The dividend stream and terminal value were then discounted back to
December 31, 1999 using discount rates of 14.0%, 15.0% and 16.0%, which rates
Merrill Lynch viewed as within the appropriate range for a company with Wells
Fargo's risk characteristics.

  In performing this analysis, Merrill Lynch used First Call earnings per share
estimates for 2000 and 2001 for Wells Fargo of $2.57 and $2.96, respectively.
For periods after 2001, earnings were assumed to increase at First Call's
estimated annual long-term earnings growth rate for Wells Fargo of 14.3%. First
Call is a recognized data service that monitors and publishes compilations of
earnings estimates by selected research analysts regarding companies of
interest to institutional investors. Merrill Lynch also assumed an annual asset
growth rate of 7.5% and further assumed that earnings in excess of those
necessary to maintain Wells Fargo's tangible common equity ratio at its then-
current value of 6.27% could be paid out as dividends. Based on the above
assumptions, Merrill Lynch determined that the stand-alone present value of the
Wells Fargo common stock ranged from $39.39 to $47.91 per share, compared to
Wells Fargo's closing market price as of January 26, 2000 of $38.00.

  The analyses set forth in each of the preceding six paragraphs do not
necessarily indicate actual values or actual future results and do not purport
to reflect the prices at which any securities may trade at the present or at
any time in the future. The discount rates applied to First Commerce and Wells
Fargo referred to in such paragraphs were based on several factors, including
the financial advisors' knowledge of each of First Commerce and Wells Fargo and
the industry in which they operate, the business risk of each company and the
overall interest rate environment as of January 28, 2000. The projected asset
growth rates applied for First Commerce and Wells Fargo took into consideration
several factors, including the historical asset growth of each

                                       18
<PAGE>

of First Commerce and Wells Fargo as well as projected long-term growth rates.
Dividend discount analysis is a widely used valuation methodology, but the
results of this methodology are highly dependent upon the numerous assumptions
that must be made, including earnings growth rates, dividend payout rates,
terminal values and discount rates.

  Five-Year Stock Price Performance. Merrill Lynch analyzed the price
performance of the First Commerce class A common stock and class B common stock
over the five-year period from December 30, 1994 to January 26, 2000 and
compared this performance to the performance of Wells Fargo common stock and
the Standard & Poors Bank Index over the same period. This analysis indicated
the following cumulative changes in price over the period:

  Peer Group Analysis--Market Trading Multiples. Merrill Lynch compared
selected operating and stock market results of First Commerce to publicly
available corresponding data for the First Commerce peer group.

  The following table compares selected financial data of First Commerce with
corresponding average data for the First Commerce peer group. The multiples
listed are based on the aggregate market value of First Commerce common stock
using the closing price as of December 14, 1999 (30 trading days prior to the
date of Merrill Lynch's presentation to the First Commerce Board). Earnings
estimates for year 2000 are based on management's projections (excluding Global
Fund securities gains) since there are no "street" estimates published for
First Commerce. Financial data is as of December 31, 1999 if available,
otherwise such data is as of September 30, 1999; and market data is as of
January 26, 2000. The calculation of price-to-2000 estimated earnings per share
is based on estimated earnings per share calculated in accordance with
generally accepted accounting principles. The calculation of price-to-2000
estimated cash earnings per share is based on estimated earnings per share plus
amortization of intangible assets per share. Year 2001 earnings estimates were
not

  Peer Group Analysis--Growth Rates and Price Earnings Growth Ratios. Merrill
Lynch also analyzed the First Call projected five-year earnings per share
growth rate of Wells Fargo compared with the Wells Fargo peer group. Merrill
Lynch determined that the First Call projected five-year earnings per share
growth rate for Wells Fargo was 14.3% compared to an average of 12.1% for the
Wells Fargo peer group. Merrill Lynch also analyzed Wells Fargo's 2000 price-
to-earnings ratio measured as a percentage of its projected five-year earnings
per share growth rate and compared this measurement to the Wells Fargo peer
group. This analysis indicated that Wells Fargo's 2000 price-to-earnings ratio
measured as a percentage of its five-year earnings per share growth rate was
90%, compared to an average of 99% for the Wells Fargo peer group.

  Peer Group Analysis--Historical Growth Analysis. Merrill Lynch also analyzed
the historical growth of Wells Fargo compared with the corresponding publicly
available data for the Wells Fargo peer group. This analysis indicated that the
three-year revenue (net interest income plus noninterest income) compound
annual growth rate of Wells Fargo and the Wells Fargo peer group was 8.9% and
8.7%, respectively, ranking Wells Fargo number 3 among 11 peers. Merrill Lynch
further determined that the three-year earnings compound annual growth rate for
Wells Fargo and the Wells Fargo peer group was 18.9% and 12.5%, respectively,
ranking Wells Fargo number 1 among 11 peers. All historical data was adjusted
to reflect subsequent transactions accounted for as "poolings-of-interests."

  Peer Group Analysis - Profitability Ratios. Merrill Lynch compared certain
profitability ratios of First Commerce and Wells Fargo to publicly available
corresponding data for the First Commerce peer group and the Wells Fargo peer

  No company or transaction used in the comparable company analyses described
above is identical to First Commerce, Wells Fargo, the pro forma combined
company, or the merger, as the case may be. Accordingly, an analysis of the
results of the foregoing necessarily involves complex considerations and
judgments concerning financial and operating characteristics and other factors
that could affect the merger, public trading or other values of the companies
to which they are being compared. Mathematical analysis (such as determining
the average or median) is not in itself a meaningful method of using comparable
transaction data or comparable company data.

  Selected Merger and Acquisition Transactions. Merrill Lynch analyzed publicly
available financial, operating, and stock market information for twelve
selected bank merger and acquisition transactions that involved commercial bank
targets in Nebraska, Kansas, Oklahoma, South Dakota, North Dakota, Missouri,
Iowa and Arkansas, that have been completed since 1997 and that involved total
consideration that ranged from $100 million to $1 billion to determine the
multiples and premiums achieved in these transactions. Merrill Lynch then
determined the imputed per share value of First Commerce common stock based on
the multiples and premiums arrived at by Merrill Lynch in its comparability
analysis.

  Merrill Lynch considered the precedent transactions to be reasonably similar
to the merger, but none of the transactions is identical to the merger. The

  In determining the 30-day market premium, Merrill Lynch used the price of
First Commerce common stock on December 14, 1999 (the date 30 trading days
prior to the date Merrill Lynch delivered its opinion). In determining the last
twelve months' return on assets and equity, the First Commerce financial
measures are based on core 1999 earnings (excluding Global Fund securities
gains) and the First Commerce balance sheet data as of December 31, 1999.

  The actual operating and financial results achieved by the pro forma combined
company may vary from projected results and variations may be material as a
result of business and operational risks, the timing, amount and costs
associated with achieving cost savings and revenue enhancements, as well as
other factors.

  First Commerce retained Merrill Lynch based upon its experience and
expertise. Merrill Lynch is an internationally recognized investment banking
and advisory firm. As part of its investment banking business, Merrill Lynch is
regularly engaged in the valuation of businesses and securities in connection
with mergers and acquisitions, negotiated underwritings, competitive biddings,
secondary distributions of listed and unlisted securities, private placements
and valuations for estate, corporate and other purposes.

  In addition, in the ordinary course of its business, Merrill Lynch and its
affiliates may actively trade the debt and equity securities of First Commerce
and Wells Fargo for their own account and/or the accounts of their respective
customers, and, accordingly, may at any time hold long or short positions in
these securities. In the past two years, Merrill Lynch has provided to Wells
Fargo financial advisory, investment banking and other services unrelated to
the proposed merger, and has received fees for the rendering of these services.
Merrill Lynch may provide these types of services to the combined company in
the future and receive fees for those services.

                                       22
<PAGE>

  Pursuant to a letter agreement between First Commerce and Merrill Lynch,
dated as of September 20, 1999, First Commerce agreed to pay Merrill Lynch the
following fees for financial advisory services rendered through the closing of
the merger:

  .  a fee of $75,000, which was paid upon the execution of the letter
     agreement;

  .  a fee of $1.25 million, which was paid upon the execution of the merger
     agreement; and

  .  a fee of approximately $2.25 million, payable in cash if and when the
     merger is completed.

  First Commerce also agreed, among other things, to reimburse Merrill Lynch
for certain expenses incurred in connection with the services provided by
Merrill Lynch, and to indemnify Merrill Lynch and its affiliates from and
against certain liabilities and expenses, which may include certain liabilities
under federal securities laws, in connection with its engagement.

Interests in the Merger That May Be Different Than Yours

  First Commerce's directors and executive officers may be considered to have
interests in the merger that are in addition to their interests as shareholders
of First Commerce generally. First Commerce's board of directors was aware of
these interests and considered them, among other things, when it approved the
merger agreement.

 Employment and Non-Competition Agreements

  In connection with the merger, First Commerce, National Bank of Commerce and
Wells Fargo entered into employment and non-compete agreements with Bradley F.
Korell, Stuart L. Bartruff, Mark W. Hansen and Jo E. Kinsey, officers of First
Commerce and National Bank of Commerce, relating to the employment of these
officers following the merger. Under the employment provisions of the
agreements, National Bank of Commerce will employ these officers in positions
substantially similar to the positions held by these officers prior to the
merger. In consideration of their employment services, Messrs. Korrell,
Bartruff and Hansen and Ms. Kinsey will receive an annual salary of $250,000,
$185,000, $190,000 and $110,000, respectively, and will be eligible to
participate in the Wells Fargo Long-Term Incentive Compensation Plan according
to its terms and Wells Fargo's policies. The term of their employment will
commence on the closing date of the merger and will expire two years later
unless earlier terminated as a result of:

  .  the officer's death;

  .  receipt by the officer of notice of termination from First Commerce,
     National Bank of Commerce or Wells Fargo arising from:

    .  the commission of a fraudulent or dishonest act by the officer or

    .  the officer's willful violation of National Bank of Commerce's or
       Wells Fargo's policies or the Wells Fargo Code of Ethics and
       Business Conduct; or

  .  the officer's voluntary resignation.

  In addition, the agreements contain non-compete and non-solicitation
provisions that apply while the executive is employed by the company and until
the second anniversary of the closing date.

                                       23
<PAGE>

 Other Interests (e.g., change in control, severance arrangements, etc.)

  In December, 1999 the Compensation Committee recommended, and the Board of
Directors of First Commerce adopted, a Retention Bonus Program. Under this
program, certain selected key officers of First Commerce and its subsidiary
banks will be paid a retention bonus in the event that a qualifying
transaction, such as the merger, is completed, provided that the respective
officer is still employed by First Commerce, or its successors, on the date
which is four months after the date of closing. The retention bonuses are also
payable in the event the employee is terminated without cause (as defined in
the Retention Bonus Program) or in the event the employee terminates his or her
employment for good reason (as defined in the Retention Bonus Program). Each
officer's retention bonus is either a fixed amount or a multiple of his or her
annual compensation, defined to include the salary paid to the employee for the
year 1999 plus the cash bonus paid to that employee for the year 1998. The
range of bonuses is from $11,700 to three times annual compensation. Payment of
a portion of the retention bonuses for employees whose retention bonus is
either two or three times annual compensation is at the discretion of the board
of directors of First Commerce based upon the Board's evaluation of the
employee's services and cooperation during the period from December 1999
through the date the transaction is completed. For First Commerce's executive
officers, other than Messrs. Stuart, Jr. and Donald Kinley, the amount of the
retention bonus is three times annual compensation; of this amount, an amount
equal to one times annual compensation is at the discretion of the Board. Mr.
Kinley's retention bonus is equal to two times his annual compensation; of this
amount, an amount equal to one times annual compensation is at the discretion
of the Board. The retention bonus for James Stuart, Jr. is $500,000, payable on
the date the transaction is completed.

 Indemnification

  Wells Fargo has agreed to ensure that all rights to indemnification and all
limitations of liability existing in First Commerce's articles of incorporation
or bylaws in favor of the present and former directors and officers of First
Commerce with respect to claims arising from (a) facts or events that occurred
before the effective time of the merger or (b) the merger agreement, the
support agreements or any of the transactions contemplated by these agreements
will survive the merger and continue in full force and effect.

  The merger agreement also provides that Wells Fargo will use its reasonable
best efforts to cover for six years following the effective time the officers
and directors of First Commerce and its subsidiaries under a director's and
officer's liability insurance policy with respect to claims arising out of
facts or events occurring before the effective time. This insurance will
provide at least the same coverage and amounts as the coverage currently
provided by First Commerce for a total premium cost of not more than 200% of
the current amount expended by First Commerce to provide this insurance. If
Wells Fargo is unable to maintain or obtain this insurance, it will use its
reasonable best efforts to obtain as much comparable insurance as is available
for a total premium cost of 200% of the current amount expended by First
Commerce to provide this insurance.

Dissenters' Rights

  Under Nebraska law, shareholders of First Commerce common stock do not have
the right to dissent to the merger, because the Nebraska dissenters' rights
statute does not apply to shareholders of a bank or bank holding company.

Exchange Of Certificates

  After completion of the merger, Norwest Bank Minnesota, National Association,
acting as exchange agent for Wells Fargo, will mail to each holder of record of
shares of First Commerce common stock a form of letter of transmittal, together
with instructions, for the exchange of the holder's First Commerce stock
certificates for a certificate representing Wells Fargo common stock.

  First Commerce shareholders should not send in their certificates until they
receive the letter of transmittal form and instructions.

                                       24
<PAGE>

  No dividend or other distribution declared on Wells Fargo common stock after
completion of the merger will be paid to the holder of any certificates for
shares of First Commerce common stock until after the certificates have been
surrendered for exchange.

  When the exchange agent receives a surrendered certificate or certificates
from a First Commerce shareholder, together with a properly completed letter of
transmittal, it will issue and mail to the shareholder a certificate
representing the number of whole shares of Wells Fargo common stock to which
the shareholder is entitled, plus cash for the amount of any remaining
fractional share and any cash dividends that are payable with respect to the
shares of Wells Fargo common stock so issued. No interest will be paid on the
fractional share amount or amounts payable as dividends or other distributions.

  A certificate for Wells Fargo common stock may be issued in a name other than
the name in which the surrendered certificate is registered if (a) the
certificate surrendered is properly endorsed and accompanied by all documents
required to transfer the shares to the new holder and (b) the person requesting
the issuance of the Wells Fargo common stock certificate either pays to the
exchange agent in advance any transfer and other taxes due or establishes to
the satisfaction of the exchange agent that such taxes have been paid or are
not due.

  The exchange agent will issue stock certificates for Wells Fargo common stock
in exchange for lost, stolen or destroyed certificates for First Commerce
common stock upon receipt of a lost certificate affidavit and a bond
indemnifying Wells Fargo for any claim that may be made against Wells Fargo as
a result of the lost, stolen or destroyed certificates.

  After completion of the merger, no transfers will be permitted on the books
of First Commerce. If, after completion of the merger, certificates for First
Commerce common stock are presented for transfer to the exchange agent, they
will be canceled and exchanged for certificates representing Wells Fargo common
stock.

  None of Wells Fargo, First Commerce, the exchange agent or any other person
will be liable to any former holder of First Commerce common stock for any
amount delivered in good faith to a public official pursuant to applicable
abandoned property, escheat or similar laws.

Regulatory Approvals

  The merger is subject to the prior approval of the Board of Governors of the
Federal Reserve System. The approval of the Federal Reserve Board is required
because Wells Fargo is a bank holding company registered under the Bank Holding
Company Act.

  Wells Fargo has filed an application with the Federal Reserve Board
requesting approval of the merger. Copies of the application have been provided
to the U.S. Department of Justice and other governmental agencies. The
application describes the terms of the merger, the parties involved, the
activities to be conducted by Wells Fargo as a result of the merger, the source
of funds for the merger and provides other financial and managerial
information. In evaluating the application, the Federal Reserve Board will
consider the financial and managerial resources and prospects of the existing
and combined institutions and the benefits that may be expected from the
merger. Among other things, the Federal Reserve Board will evaluate the capital
adequacy of Wells Fargo before and after completion of the merger.

  The Federal Reserve Board may deny an application if it determines that the
transaction would result in a monopoly or be in furtherance of any combination
or conspiracy to monopolize or attempt to monopolize a given business activity
in any part of the United States. The Federal Reserve Board may also deny an
application if it determines that the transaction would substantially lessen
competition or would tend to create a monopoly in any section of the country,
or would in any other manner result in a restraint of trade, unless the Federal
Reserve Board finds that the anti-competitive effects of the transaction are
clearly outweighed by the probable effects of the transaction in providing
benefits to the public. Wells Fargo and First Commerce expect

                                       25
<PAGE>

that a modest level of divestitures may be required in connection with
obtaining Federal Reserve Board approval of the merger.

  Applicable federal law provides for the publication of notice and public
comment on the application filed by Wells Fargo with the Federal Reserve Board.
Under current law, the merger may not be completed until the Federal Reserve
Board has approved the merger and a period of 30 days, or fewer if prescribed
by the Federal Reserve Board with the concurrence of the Attorney General of
the United States, following the date of approval by the Federal Reserve Board,
has expired. Wells Fargo filed an application with the Federal Reserve Board on
March 30, 2000. As of the date of this document, the Federal Reserve Board had
not acted on Wells Fargo's application.

  Prior approval of the merger is also required from the Colorado State Bank
Commissioner. First Commerce also owns all of the outstanding capital stock of
First Commerce Technologies, Inc. As a result of the acquisition of First
Commerce, Wells Fargo will also acquire FCTI, which will require that prior
notice be given to the Federal Trade Commission under the Hart Scott Rodino
Antitrust Improvements Act.

  The approval of an application means only that the regulatory criteria for
approval have been satisfied or waived. It does not mean that the approving
authority has determined that the consideration to be received by First
Commerce shareholders is fair. Regulatory approval does not constitute an
endorsement or recommendation of the merger.

  Wells Fargo and First Commerce are not aware of any governmental approvals or
compliance with banking laws and regulations that are required for the merger
to become effective other than those described above. Wells Fargo and First
Commerce intend to seek any other approval and to take any other action that
may be required to effect the merger. There can be no assurance that any
required approval or action can be obtained or taken prior to the special
meeting.

  The merger cannot be completed unless all necessary regulatory approvals are
granted and all statutory waiting periods thereafter have expired. In addition,
Wells Fargo may elect not to complete the merger if any condition under which
any regulatory approval is granted is unreasonably burdensome to Wells Fargo.
However, a divestiture that is required as a condition to a regulatory approval
will not be deemed to be unreasonably burdensome to Wells Fargo if the
divestiture is consistent with U.S. Department of Justice and Federal Reserve
Board guidelines, policies and practices concerning the merger of bank holding
companies that have been used in transaction that have recently been reviewed
by those agencies prior to the date of the merger agreement. See "The Merger
Agreement--Conditions To The Merger" and "--Termination Of The Merger
Agreement."

Effect Of Merger On First Commerce's Employee Benefit Plans

  Each person who is an employee of First Commerce or a First Commerce
subsidiary as of the effective date of the merger will be eligible for the
employee welfare plans of Wells Fargo specified in the merger agreement,
subject to any eligibility requirements applicable to such plans. Eligible
employees will enter the specified plans not later than January 1, 2001.

  Each person who is an employee of First Commerce or a First Commerce
subsidiary as of the effective date of the merger will be eligible for
participation in the Wells Fargo 401(k) plan, subject to any eligibility
requirements applicable to such plan. Each such employee shall also be eligible
for participation in the Wells Fargo cash balance plan pursuant to the terms
thereof, and shall be eligible for access to Wells Fargo's retiree medical
benefit, subject to any applicable eligibility requirements. Wells Fargo shall
recognize years of past service with First Commerce or a First Commerce
subsidiary and any predecessor of First Commerce or a First Commerce subsidiary
for the purpose of eligibility to access Wells Fargo's retiree medical benefit.

  Each person who is an employee of First Commerce or a First Commerce
subsidiary as of the effective date of the merger will be eligible for
participation in the employee benefit plans of Wells Fargo on the same

                                       26
<PAGE>

basis as similarly situated employees of Wells Fargo, and Wells Fargo will give
each employee of First Commerce credit for prior service with First Commerce or
its subsidiaries, and any of their predecessors, for purposes of eligibility,
vesting and levels of benefits under the Wells Fargo employee benefit plans for
which the employee is eligible, subject to any eligibility requirements
applicable to these plans. Eligible employees will enter the specified plans on
the effective date of the merger or on such later date on which the employee
becomes eligible to participate upon conversion to Wells Fargo's payroll
systems.

U.S. Federal Income Tax Consequences Of The Merger

  The following is a summary of the material anticipated U.S. federal income
tax consequences of the merger to First Commerce shareholders who hold First
Commerce common stock as a capital asset. The summary is based on the U.S. tax
code, regulations under the U.S. tax code, administrative rulings and court
decisions, as in effect as of the date of this document, all of which are
subject to change at any time, possibly with retroactive effect. This summary
is not a complete description of all of the tax consequences of the merger. In
particular, this summary may not address U.S. federal income tax considerations
applicable to you if you are a First Commerce shareholder subject to special
treatment under U.S. federal income tax law, including, for example:

  .  foreign persons

  .  financial institutions

  .  dealers in securities

  .  traders in securities who elect to apply a mark-to-market method of
     accounting

  .  insurance companies

  .  tax-exempt entities

  .  holders who dissent from the merger and receive the fair value of their
     shares of First Commerce common stock in cash

  .  holders who acquired their shares of First Commerce common stock through
     exercise of an employee stock option or right, or otherwise as
     compensation

  .  holders who hold First Commerce common stock as part of a hedge,
     straddle, conversion or constructive sale transaction.

  In addition, First Commerce does not provide any information in this document
about the tax consequences of the merger under applicable foreign, state or
local laws or under any federal laws other than those relating to the income
tax.

  First Commerce urges you to consult with your tax advisors about the
particular tax consequences of the merger to you, including the effects of U.S.
federal, state or local, or foreign and other tax laws.

  [In connection with the filing with the SEC of the registration statement
containing this document, the law firm of Wachtell, Lipton, Rosen & Katz has
delivered to Wells Fargo and First Commerce an opinion addressing the material
U.S. federal income tax consequences of the merger. This opinion has been
rendered on the basis of facts, representations and assumptions set forth or
referred to in the opinion. In rendering this opinion, Wachtell, Lipton, Rosen
& Katz required and relied upon factual representations contained in
certificates of officers of Wells Fargo and First Commerce. The opinion is to
the effect that, for U.S. federal income tax purposes:

  .  the merger will constitute a reorganization within the meaning of
     Section 368 of the U.S. tax code;

  .  no gain or loss will be recognized by the holders of First Commerce
     common stock upon receipt of Wells Fargo common stock, except with
     respect to cash received instead of fractional shares of Wells Fargo
     common stock;

                                       27
<PAGE>

  .  the basis of Wells Fargo common stock received, including fractional
     shares deemed received and redeemed as described below, by the
     shareholders of First Commerce will be the same as the basis of the
     First Commerce common stock exchanged therefor; and

  .  the holding period of shares of Wells Fargo common stock received,
     including fractional shares deemed received and redeemed as described
     below, by the shareholders of First Commerce will include the holding
     period of the First Commerce common stock, provided that the shares of
     First Commerce common stock were held as a capital asset as of the
     effective time of the merger.]

  First Commerce will not be required to complete the merger unless it receives
an additional opinion of its counsel, dated the closing date of the merger,
based on the facts and assumptions stated in that opinion, substantially to the
same effect as the opinion described above. In rendering that opinion, counsel
may require and rely on customary representations contained in certificates of
officers of Wells Fargo, First Commerce and others.

  None of the tax opinions delivered or to be delivered to the parties in
connection with the merger as described in this document are binding on the
Internal Revenue Service or the courts, and First Commerce does not intend to
request a ruling from the IRS with respect to the merger.

  If you receive cash instead of a fractional share interest in Wells Fargo
common stock, you will be treated as having received that fractional share
interest and then as having received the cash in redemption of the fractional
share interest, and in most cases you should recognize capital gain or loss for
U.S. federal income tax purposes measured by the difference between the amount
of cash received and the portion of the tax basis of the share of First
Commerce common stock allocable to the fractional share interest. This capital
gain or loss would be a long-term capital gain or loss if the holding period
for the fractional share interest in Wells Fargo common stock is greater than
one year at the effective time.

  Information Reporting and Backup Withholding. Payments related to First
Commerce common stock may be subject to information reporting to the IRS and to
a 31% backup withholding tax. Backup withholding will not apply, however, to a
payment to you, or another payee, if you or the payee completes and signs the
substitute Form W-9 that will be included as part of the transmittal letter, or
otherwise proves to Wells Fargo and the exchange agent that you or the payee is
exempt from backup withholding.

Support Agreements

  At the same time that the merger agreement was signed, Richard C. Schmoker,
William C. Schmoker, Kenneth W. Staab, John C. Osborne, John G. Lowe, III,
Connie Lapaseotes, David T. Calhoun and Scott Stuart, non-employee directors of
First Commerce; James Stuart, Jr., chairman and chief executive officer of
First Commerce; Brad Korell, president of National Bank of Commerce Trust &
Savings Association; Stuart L. Bartruff, executive vice president and secretary
of First Commerce; James Stuart III, Chairman and CEO of First Commerce
Investors, Inc. and Mark Hansen, executive vice president of First Commerce,
entered into individual support agreements with Wells Fargo. Under the support
agreements, these individuals agreed, among other things:

  .  not to sell or transfer any shares of First Commerce common stock held
     by them except (a) pursuant to the merger, (b) in connection with the
     exercise of stock options or (c) with Wells Fargo's prior written
     consent;

  .  to vote in favor of the merger all shares of First Commerce common stock
     owned by them at the record date for any meeting of shareholders of
     First Commerce called to consider and vote on the merger;

  .  not to solicit any inquiries or proposals or enter into any discussions,
     negotiations or agreements relating to a business combination, merger or
     consolidation of First Commerce with any person other than Wells Fargo;
     and

  .  not to vote in favor of any business combination, merger or
     consolidation of First Commerce with any person other than Wells Fargo.

                                       28
<PAGE>

  At the record date for the special meeting, the individuals signing the
support agreements beneficially owned a total of 1,564,886 shares of First
Commerce class A common stock and 5,982,421 shares of First Commerce class B
common stock, respectively. These shares represent approximately 60.9% of the
shares of First Commerce class A common stock and approximately 55.5% of the
shares of First Commerce class B common stock entitled to vote at the special
meeting.

Resale Of Wells Fargo Common Stock Issued In The Merger

  The Wells Fargo common stock issued in the merger will be freely transferable
under the Securities Act of 1933, except for shares issued to First Commerce
shareholders who are considered to be "affiliates" of First Commerce or Wells
Fargo under Rule 145 under the Securities Act or of Wells Fargo under Rule 144
under the Securities Act. The definition of "affiliate" is complex and depends
on the specific facts, but generally includes directors, executive officers,
10% stockholders and other persons with the power to direct the management and
policies of the company in question.

  Affiliates of First Commerce may not sell the shares of Wells Fargo common
stock received in the merger except:

  .  pursuant to an effective registration statement under the Securities
     Act;

  .  in compliance with an exemption from the registration requirements of
     the Securities Act; or

  .  in compliance with Rule 145 under the Securities Act.

Generally, those rules permit resales of stock received by First Commerce
affiliates during the year following the completion of the merger so long as
Wells Fargo has complied with certain reporting requirements and the selling
shareholder complies with certain volume and manner of sale restrictions, and
freely thereafter.

  First Commerce has agreed to use its best efforts to deliver to Wells Fargo
signed representations by each person who may be deemed to be an affiliate of
First Commerce that the person will not sell, transfer or otherwise dispose of
the shares of Wells Fargo common stock to be received by the person in the
merger except in compliance with the applicable provisions of the Securities
Act and the rules and regulations promulgated thereunder.

  This document does not cover any resales of Wells Fargo common stock received
by affiliates of First Commerce.

Stock Exchange Listing

  The shares of Wells Fargo common stock to be issued in the merger will be
listed on the New York Stock Exchange and the Chicago Stock Exchange. The
listing of the Wells Fargo common stock to be issued in the merger is a
condition to First Commerce's obligation to complete the merger.

Accounting Treatment

  Wells Fargo will account for the merger as a purchase. Wells Fargo will
record, at fair value, the acquired assets and assumed liabilities of First
Commerce. To the extent the total purchase price exceeds the fair value of the
assets acquired and liabilities assumed, Wells Fargo will record goodwill.
Wells Fargo will include in its results of operations the results of First
Commerce's operations after the merger.

  The unaudited pro forma data included in this proxy statement-prospectus for
the merger have been prepared using the purchase method of accounting. See
"Summary--Comparative Per Common Share Data."

                              THE MERGER AGREEMENT

  The following is a summary of certain provisions of the merger agreement. A
copy of the merger agreement is attached to this document as Appendix A and is
incorporated by reference into this document. This summary is qualified in its
entirety by reference to the full text of the merger agreement. First Commerce
shareholders are encouraged to read the merger agreement carefully and in its
entirety. Parenthetical references are to the relevant paragraph or paragraphs
of the merger agreement.

Basic Plan Of Merger

  The merger agreement provides that a wholly-owned subsidiary of Wells Fargo
will merge by statutory merger with and into First Commerce, with First
Commerce as the surviving corporation. (paragraph 1(a))

 Exchange Of Wells Fargo Shares For First Commerce Shares

  Under the merger agreement, each share of First Commerce common stock
outstanding immediately before the merger is to be converted into the right to
receive the number of shares of Wells Fargo common stock determined by dividing
$35.95 by the Wells Fargo Measurement Price, which is the average of the
closing prices of a share of Wells Fargo common stock as reported on the
consolidated tape of the New York Stock Exchange during the measurement period
of 20 trading days ending on June [8], 2000, the day immediately preceding the
special meeting. (paragraph 1(a))

  Since the price of Wells Fargo common stock will fluctuate, First Commerce
cannot assure you as to what the price of Wells Fargo common stock will be
during the measurement period used to determine the Wells Fargo Measurement
Price and, therefore, First Commerce cannot assure you as to the number of
shares of Wells Fargo common stock you will receive in the merger, although
that number will in all events have a value equivalent to $35.95 based on the
Wells Fargo Measurement Price, less any cash you receive in lieu of a
fractional share of Wells Fargo common stock. As an example, however, assume
the special meeting had taken place on April 15, 2000. The average closing
price of Wells Fargo common stock as reported on the consolidated tape of the
New York Stock Exchange during the measurement period of 20 trading days ending
on April 14, 2000, the day immediately preceding this hypothetical special
meeting, was $40.708. In this example, you would receive 0.883119 shares of
Wells Fargo common stock for each share of First Commerce common stock you own
on the record date.

 No Adjustments For Price Fluctuations

  No adjustment will be made to the number of shares of Wells Fargo common
stock you will receive for your shares of First Commerce common stock to
reflect fluctuations in the price of Wells Fargo common stock occurring after
the special meeting.

 Adjustments For Changes In Capitalization

  If, before the merger is completed, the outstanding shares of Wells Fargo are
increased or decreased in number or changed into or exchanged for a different
number or kind of shares or securities as a result of a reorganization,
reclassification, recapitalization, stock dividend, stock split or other
similar change in capitalization, then an appropriate and proportionate
adjustment will be made to the exchange ratio. (paragraph 1(b))

 Cash In Lieu Of Fractional Shares

  If the aggregate number of shares of Wells Fargo common stock you will
receive in the merger does not equal a whole number, you will receive cash
instead of the fractional share. The cash payment will be equal to the product
of the fractional part of the share of Wells Fargo common stock multiplied by
the average of the

                                       30
<PAGE>

closing prices of a share of Wells Fargo common stock as reported on the
consolidated tape of the New York Stock Exchange for each of the five trading
days ending on the second day immediately preceding the effective date of the
merger. (paragraph 1(c))

 Treasury Shares

  Shares of First Commerce common stock held by First Commerce or Wells Fargo,
other than shares held in a fiduciary capacity for third parties, such as
shares held in trust accounts, managed accounts and the like, and any shares
held by First Commerce or Wells Fargo or any of their subsidiaries in respect
of debts previously contracted, will be canceled and will not be converted into
the right to receive Wells Fargo common shares.

 Effective Date And Time Of The Merger

  The effective date of the merger will be the day on which a certificate of
merger is filed with and accepted by the Nebraska Secretary of State. The
merger agreement provides that a certificate of merger will be filed within
five business days after the satisfaction or waiver of all conditions to the
merger or on such other date as Wells Fargo and First Commerce may agree. See
"Conditions To The Merger." The effective time of the merger will be 11:59
p.m., Lincoln, Nebraska time, on the effective date of the merger. (paragraph
1(e))

 Revised Merger Structure

  Subject to the conditions described below, Wells Fargo has the right under
the merger agreement to revise the structure of the proposed transaction so
that:

  .  First Commerce is merged into a subsidiary of Wells Fargo; or

  .  First Commerce is merged directly into Wells Fargo.

  Wells Fargo may revise the structure of the transaction only if the revised
structure does not:

  .  change the amount or kind of consideration to be received by First
     Commerce in the merger;

  .  adversely affect the tax treatment of the merger to First Commerce
     shareholders; and

  .  impede or delay the completion of the merger.

  Assuming these conditions are met, Wells Fargo may revise the structure of
the transaction without notice to you.

Fargo and First Commerce concerning, among other things (paragraphs 2 and 3):

 Termination by Either Wells Fargo or First Commerce

  Either Wells Fargo or First Commerce can terminate the merger agreement
without the consent of the other if any of the following occurs:

  .  The merger has not been completed by October 31, 2000, unless the

                         INFORMATION ABOUT WELLS FARGO

General

  Wells Fargo is a diversified financial services company. Through its
subsidiaries and affiliates, Wells Fargo provides retail, commercial, real
estate and mortgage banking, asset management and consumer finance, as well as
a variety of other financial services, including equipment leasing,
agricultural finance, securities brokerage and investment banking, insurance
agency services, computer and data processing services, trust services,
mortgage-backed securities servicing, and venture capital investment.

  At March 31, 2000, Wells Fargo had consolidated total assets of $    billion,
consolidated total deposits of $    billion and stockholders' equity of $
billion. Based on assets at March 31, 2000, Wells Fargo was the  th largest
commercial banking organization in the United States.

  Wells Fargo expands its business in part by acquiring banking institutions
and other companies engaged in activities closely related to banking. Wells
Fargo continues to explore opportunities to acquire banking institutions and
other companies permitted by the Bank Holding Company Act of 1956. Discussions
are continually being carried on related to such acquisitions. It is not
presently known whether, or on what terms, such discussions will result in
further acquisitions. It is the policy of Wells Fargo not to comment on such
discussions or possible acquisitions until a definitive agreement with respect
thereto has been signed.

  Wells Fargo is a legal entity separate and distinct from its banking and non-
banking subsidiaries. As a result, the right of Wells Fargo--and thus the right
of Wells Fargo's creditors--to participate in any distribution of assets or
earnings of any subsidiary, other than in its capacity as a creditor of such
subsidiary, is subject to the prior payment of claims of creditors of such
subsidiary. The principal sources of Wells Fargo's revenues are dividends and
fees from its subsidiaries. See "Regulation And Supervision Of Wells Fargo--
Dividend Restrictions" for a discussion of the restrictions on the subsidiary
banks' ability to pay dividends to Wells Fargo.

  Wells Fargo's principal executive offices are located at 420 Montgomery
Street, San Francisco, California 94163, and its telephone number is (800) 411-
4932.

Management And Additional Information

  Information concerning executive compensation, the principal holders of
voting securities, certain relationships and related transactions, and other
related matters concerning Wells Fargo is included or incorporated by reference
in its annual report on Form 10-K for the year ended December 31, 1999. Wells
Fargo's annual report on Form 10-K is incorporated by reference into this proxy
statement-prospectus. First Commerce shareholders who want a copy of this
annual report or any document incorporated by reference into the report may
contact Wells Fargo at the address or phone number indicated below under "Where
You Can Find More Information."

Competition

  The financial services industry is highly competitive. Wells Fargo's
subsidiaries compete with financial services providers, such as banks, savings
and loan associations, credit unions, finance companies, mortgage banking
companies, insurance companies, and money market and mutual fund companies.
They also face increased competition from non-banking institutions such as
securities firms and insurance companies, as well as from financial services
subsidiaries of commercial and manufacturing companies. Many of these
competitors enjoy the benefits of advanced technology, fewer regulatory
constraints and lower cost structures.

  Effective March 13, 2000, securities firms and insurance companies that elect
to become financial holding companies may acquire banks and other financial
institutions. This may significantly change the competitive environment in
which Wells Fargo and its subsidiaries conduct business. The financial services
industry is also

                                       37
<PAGE>

likely to become more competitive as further technological advances enable more
companies to provide financial services. These technological advances may
diminish the importance of depository institutions and other financial
intermediaries in the transfer of funds between parties.

Information On Wells Fargo's Web Site

  Information on the internet web site of Wells Fargo or any subsidiary of
Wells Fargo is not part of this proxy statement-prospectus, and you should not
rely on that information in deciding whether to approve the merger unless that
information is also in this proxy statement-prospectus or in a document that is
incorporated by reference into this proxy statement-prospectus.

                             FIRST SECURITY MERGER

  The following information describes the pending merger transaction between
Wells Fargo & Company and First Security Corporation. Wells Fargo will acquire
First Security as a result of the transaction. The description is not complete
and is qualified in its entirety by reference to the more detailed information

2000 and filed on April 21, 2000. The Form 8-K is incorporated herein by
reference.

The First Security Merger Transaction

  On April 9, 2000, Wells Fargo and First Security entered into a merger
agreement that provides for the merger of a wholly-owned subsidiary of Wells
Fargo in First Security, with First Security surviving as a wholly-owned
subsidiary of Wells Fargo. If the First Security merger is completed, each
outstanding share of First Security common stock will be converted into 0.355
of a share of Wells Fargo common stock. Wells Fargo expects to issue
approximately 71.6 million shares of its common stock in the First Security
merger, representing approximately        of Wells Fargo common stock
outstanding as of March 31, 2000. First Security has granted to Wells Fargo an
option exercisable, in whole or in part, upon the occurrence of specified
conditions, to purchase up to 19.9% of the outstanding shares of First Security
common stock.

  The First Security merger is subject of a number of conditions, including
approvals by First Security stockholders and regulatory agencies. No vote of
Wells Fargo stockholders is required to complete the First Security merger.
Wells Fargo expects to complete the First Security merger in the third quarter
of 2000, after the Wells Fargo/First Commerce merger closes. Wells Fargo cannot
guarantee when or if the merger with First Security will be completed.

                   REGULATION AND SUPERVISION OF WELLS FARGO

  To the extent that the following information describes statutory and
regulatory provisions, it is qualified in its entirety by reference to the full
text of those provisions. Also, such statutes, regulations and policies are
continually under review by Congress and state legislatures and federal and
state regulatory agencies. A change in statutes, regulations or regulatory
policies applicable to Wells Fargo could have a material effect on the business
of Wells Fargo.

Introduction

  Wells Fargo, its banking subsidiaries and many of its non-banking
subsidiaries are subject to extensive regulation by federal and state agencies.
The regulation of bank holding companies and their subsidiaries is intended
primarily for the protection of depositors, federal deposit insurance funds and
the banking system as a whole and not for the protection of security holders.

  As discussed in more detail below, this regulatory environment, among other
things, may restrict Wells Fargo's ability to diversify into certain areas of
financial services, acquire depository institutions in certain states and pay
dividends on its capital stock. It may also require Wells Fargo to provide
financial support to one or more of its banking subsidiaries, maintain capital
balances in excess of those desired by management and pay higher deposit
insurance premiums as a result of the deterioration in the financial condition
of depository institutions in general.

  Additional information about the regulation and supervision of Wells Fargo is
contained in Wells Fargo's annual and quarterly reports filed with the SEC. See
"Where You Can Find More Information."

Regulatory Agencies

 Bank Holding Company

  Wells Fargo & Company, as a bank holding company, is subject to regulation
under the Bank Holding Company Act of 1956 and to inspection, examination and
supervision by the Board of Governors of the Federal Reserve System under the
Bank Holding Company Act. As of March 13, 2000, Wells Fargo became a financial
holding company under the Bank Holding Company Act.

 Subsidiary Banks

  Wells Fargo's national banking subsidiaries are subject to regulation and
examination primarily by the Office of the Comptroller of the Currency and
secondarily by the Federal Reserve Board and the Federal Deposit Insurance
Corporation. Wells Fargo's state-chartered banking subsidiaries are subject to
primary federal regulation and examination by the FDIC or the Federal Reserve
Board and, in addition, are regulated and examined by banking departments of
the states where they are chartered.

 Nonbank Subsidiaries

  Many of Wells Fargo's non-bank subsidiaries also are subject to regulation by
the Federal Reserve Board and other applicable federal and state agencies.
Wells Fargo's brokerage subsidiaries are regulated by the SEC, the National
Association of Securities Dealers, Inc. and state securities regulators. Wells
Fargo's insurance subsidiaries are subject to regulation by applicable state
insurance regulatory agencies. Other non-bank subsidiaries of Wells Fargo are
subject to the laws and regulations of both the federal government and the
various states in which they conduct business.

Bank Holding Company Activities

 "Financial in Nature" Requirement

underwriting and agency, merchant banking, and activities that the Federal
Reserve Board has previously determined to be closely related to banking. A
bank holding company that is not also a financial holding company is limited to
engaging in banking and such other activities determined by the Federal Reserve
Board to be closely related to banking.

  No Federal Reserve Board approval is required for Wells Fargo to acquire a
company, other than a bank holding company, bank or savings association,
engaged in activities that are financial in nature or incidental to activities
that are financial in nature, as determined by the Federal Reserve Board. Prior
Federal Reserve Board approval is required before Wells Fargo may acquire the
beneficial ownership or control of more than 5% of the voting shares or
substantially all of the assets of a bank holding company, bank or savings
association.

  If any subsidiary bank of Wells Fargo ceases to be "well capitalized" or
"well managed" under applicable regulatory standards, the Federal Reserve Board
may, among other actions, order Wells Fargo to divest the subsidiary bank.
Alternatively, Wells Fargo may elect to conform its activities to those
permissible for a bank holding company that is not also a financial holding
company. If any subsidiary bank of Wells Fargo receives a rating under the
Community Reinvestment Act of 1977 of less than satisfactory, Wells Fargo will
be prohibited from engaging in new activities or acquiring companies other than
bank holding companies, banks or savings associations.

 Interstate Banking

  Under the Riegle-Neal Interstate Banking and Branching Efficiency Act of
1994, a bank holding company may acquire banks in states other than its home
state, subject to any state requirement that the bank has been organized and
operating for a minimum period of time, not to exceed five years, and the
requirement that the bank holding company not control, prior to or following
the proposed acquisition, more than 10% of the total amount of deposits of
insured depository institutions nationwide or, unless the acquisition is the
bank holding company's initial entry into the state, more than 30% of such
deposits in the state, or such lesser or greater amount set by the state. The
Riegle-Neal Act also authorizes banks to merge across state lines, thereby
creating interstate branches. States were permitted to opt out of the Riegle-
Neal Act and, by doing so, prohibit interstate mergers in the state.

 Regulatory Approval

  In determining whether to approve a proposed bank acquisition, federal
banking regulators will consider, among other factors, the effect of the
acquisition on competition, the public benefits expected to be received from
the acquisition, the projected capital ratios and levels on a post-acquisition
basis, and the acquiring institution's record of addressing the credit needs of
the communities it serves, including the needs of low and moderate income
neighborhoods, consistent with the safe and sound operation of the bank, under
the Community Reinvestment Act of 1977.

Dividend Restrictions

  Wells Fargo & Company is a legal entity separate and distinct from its
subsidiary banks and other subsidiaries. Its principal source of funds to pay
dividends on its common and preferred stock and debt service

                                       40
<PAGE>

on its debt is dividends from its subsidiaries. Various federal and state
statutory provisions and regulations limit the amount of dividends that Wells
Fargo's bank subsidiaries may pay without regulatory approval. Dividends
payable by a national bank without the express approval of the OCC are limited
to the bank's retained net profits for the preceding two calendar years plus
retained net profits up to the date of any dividend declaration in the current
calendar year. The OCC defines retained net profits as net income, less
dividends declared during the period, both of which are based on regulatory
accounting principles. Wells Fargo's state-chartered subsidiary banks also are
subject to state regulations that limit dividends.

  Before Wells Fargo Bank, National Association can declare dividends in 2000
without the prior approval of the OCC, it must have net income of approximately
$500 million plus an amount equal to or greater than the dividends declared in
2000. Because it is not expected to meet this requirement, Wells Fargo Bank,
National Association will likely be required to obtain the prior approval of
the OCC before it declares any dividends in 2000.

  Federal bank regulatory agencies have the authority to prohibit Wells Fargo's
subsidiary banks from engaging in unsafe or unsound practices in conducting
their businesses. The payment of dividends, depending on the financial
condition of the bank in question, could be deemed an unsafe or unsound
practice. The ability of Wells Fargo's subsidiary banks to pay dividends in the
future is currently influenced, and could be further influenced, by bank
regulatory policies and capital guidelines.

Holding Company Structure

 Transfer of Funds from Banking Subsidiaries

  Wells Fargo's banking subsidiaries are subject to restrictions under federal
law that limit the transfer of funds or other items of value from these
subsidiaries to Wells Fargo and its non-banking subsidiaries, including
affiliates, whether in the form of loans and other extensions of credit,
investments and asset purchases, or as other transactions involving the
transfer of value from a subsidiary to an affiliate or for the benefit of an
affiliate. Unless an exemption applies, these transactions by a banking
subsidiary with a single affiliate are limited to 10% of the subsidiary bank's
capital and surplus and, with respect to all covered transactions with
affiliates in the aggregate, to 20% of the subsidiary bank's capital and
surplus. Also, loans and extensions of credit to affiliates generally are
required to be secured in specified amounts.

 Source of Strength Doctrine

  Under current Federal Reserve Board policy, Wells Fargo is expected to act as
a source of financial and managerial strength to each of its subsidiary banks
and, under appropriate circumstances, to commit resources to support each such
subsidiary bank. This support could be required at times when Wells Fargo might
not have the resources to provide it. In addition, the OCC may order the pro
rata assessment of Wells Fargo if the capital of one of its national bank
subsidiaries were to become impaired. If Wells Fargo failed to pay the
assessment within three months, the OCC could order the sale of its stock in
the national bank subsidiary to cover the deficiency.

  Capital loans from Wells Fargo to any of its subsidiary banks are subordinate
in right of payment to deposits and certain other indebtedness of the
subsidiary bank. In the event of Wells Fargo's bankruptcy, any commitment by
Wells Fargo to a federal bank regulatory agency to maintain the capital of a
subsidiary bank will be assumed by the bankruptcy trustee and entitled to a
priority of payment.

 Depositor Preference

  The FDI Act provides that, in the event of the "liquidation or other
resolution" of an insured depository institution, the claims of depositors of
the institution, including the claims of the FDIC as subrogee of insured
depositors, and certain claims for administrative expenses of the FDIC as a
receiver will have priority over

                                       41
<PAGE>

other general unsecured claims against the institution. If an insured
depository institution fails, insured and uninsured depositors, along with the
FDIC, will have priority in payment ahead of unsecured, nondeposit creditors,
including Wells Fargo.

 Liability of Commonly Controlled Institutions

  All of Wells Fargo's banks are insured by the FDIC. FDIC-insured depository
institutions can be held liable for any loss incurred, or reasonably expected
to be incurred, by the FDIC due to the default of an FDIC-insured depository
institution controlled by the same bank holding company, or for any assistance
provided by the FDIC to an FDIC-insured depository institution controlled by
the same bank holding company that is in danger of default. "Default" means
generally the appointment of a conservator or receiver. "In danger of default"
means generally the existence of certain conditions indicating that a default
is likely to occur in the absence of regulatory assistance.

Capital Requirements

 General

  Wells Fargo is subject to risk-based capital requirements and guidelines
imposed by the Federal Reserve Board. These are substantially similar to the
capital requirements and guidelines imposed by the OCC and the FDIC on the
depository institutions under their jurisdictions. For this purpose, a
depository institution's or holding company's assets, and some of its specified
off-balance sheet commitments and obligations, are assigned to various risk
categories. A depository institution's or holding company's capital, in turn,
is classified in one of three tiers, depending on type:

                           Supplementary ("Tier 2")    Market Risk ("Tier 3")
 Core ("Tier 1") Capital   Capital                             Capital
 -----------------------   ------------------------    ----------------------

 . common equity             among other items:         . qualifying unsecured
                                                         subordinated debt
 . retained earnings        . perpetual preferred
                             stock not meeting the
 . qualifying                 Tier 1 definition
  noncumulative
  perpetual preferred      . qualifying mandatory
  stock                      convertible securities

 . a limited amount of      . qualifying
  qualifying cumulative      subordinated debt
  perpetual preferred
  stock at the holding     . allowances for loan
  company level              and lease losses,
                             subject to
 . minority interests in      limitations
  equity accounts of
  consolidated
  subsidiaries

 . less goodwill and most
  intangible assets

  Wells Fargo, like other bank holding companies, currently is required to
maintain Tier 1 capital and "total capital" (the sum of Tier 1, Tier 2 and Tier
3 capital) equal to at least 4% and 8%, respectively, of its total risk-
weighted assets (including various off-balance-sheet items, such as standby
letters of credit). For a holding company to be considered "well capitalized"
for regulatory purposes, its Tier 1 and total capital ratios must be 6% and 10%
on a risk-adjusted basis, respectively. At March 31, 2000, Wells Fargo met both
requirements, with Tier 1 and total capital equal to  % and  % of its
respective total risk-weighted assets.

                                       42
<PAGE>

  Federal Reserve Board, FDIC and OCC rules require Wells Fargo to incorporate
market and interest rate risk components into its risk-based capital standards.
Under these market risk requirements, capital is allocated to support the
amount of market risk related to a financial institution's ongoing trading
activities.

  The Federal Reserve Board also requires bank holding companies to maintain a
minimum "leverage ratio" (Tier 1 capital to adjusted total assets) of 3% if the
holding company has the highest regulatory rating and meets other requirements,
or of 3% plus an additional "cushion" of at least one to two percentage points
if the holding company does not meet these requirements. Wells Fargo's leverage
ratio at March 31, 2000 was  %.

  The Federal Reserve Board may set capital requirements higher than the
minimums described above for holding companies whose circumstances warrant it.
For example, holding companies experiencing or anticipating significant growth
may be expected to maintain capital positions substantially above the minimum
supervisory levels without significant reliance on intangible assets. The
Federal Reserve Board has also indicated that it will consider a "tangible Tier
1 capital leverage ratio" (deducting all intangibles) and other indications of
capital strength in evaluating proposals for expansion or new activities.

  Wells Fargo's banking subsidiaries are subject to similar risk-based and
leverage capital requirements adopted by its applicable federal banking agency.
Wells Fargo's management believes that each of Wells Fargo's subsidiary banks
met all capital requirements to which they are subject.

  Failure to meet capital requirements could subject a bank to a variety of
enforcement remedies, including the termination of deposit insurance by the
FDIC, and to restrictions on its business, which are described under "--Federal
Deposit Insurance Corporation Improvement Act of 1991."

 Federal Deposit Insurance Corporation Improvement Act of 1991

  The Federal Deposit Insurance Corporation Improvement Act of 1991, among
other things, identifies five capital categories for insured depository
institutions: well capitalized, adequately capitalized, undercapitalized,
significantly undercapitalized and critically undercapitalized. It requires
U.S. federal bank regulatory agencies to implement systems for "prompt
corrective action" for insured depository institutions that do not meet minimum
capital requirements based on these categories. The FDICIA imposes
progressively more restrictive constraints on operations, management and
capital distributions, depending on the category in which an institution is
classified. Unless a bank or thrift is well capitalized, it is subject to
restrictions on its ability to offer brokered deposits and on other aspects of
its operations. An undercapitalized bank or thrift must develop a capital
restoration plan, and its parent holding company must guarantee the bank's or
thrift's compliance with the plan up to the lesser of 5% of the bank's or
thrift's assets at the time it became undercapitalized and the amount needed to
comply with the plan.

  As of March 31, 2000, Wells Fargo believes that each of its significant bank
subsidiaries was well capitalized, based on the prompt corrective action ratios
and guidelines described above. A bank's capital category is determined solely
for the purpose of applying the OCC's or the FDIC's prompt corrective action
regulations, and the capital category may not constitute an accurate
representation of the bank's overall financial condition or prospects for other
purposes.

Deposit Insurance Assessments

  Through the Bank Insurance Fund, the FDIC insures the deposits of Wells
Fargo's depository institution subsidiaries up to prescribed limits for each
depositor. The amount of FDIC assessments paid by each BIF member institution
is based on its relative risk of default as measured by regulatory capital
ratios and other factors. Specifically, the assessment rate is based on the
institution's capitalization risk category and supervisory subgroup category.
An institution's capitalization risk category is based on the FDIC's
determination of whether the institution is well capitalized, adequately
capitalized or less than adequately capitalized. An institution's

                                       43
<PAGE>

supervisory subgroup category is based on the FDIC's assessment of the
financial condition of the institution and the probability that FDIC
intervention or other corrective action will be required.

  The BIF assessment rate currently ranges from zero to $0.27 per $100 of
domestic deposits. The FDIC may increase or decrease the assessment rate
schedule on a semi-annual basis. An increase in the BIF assessment rate could
have a material adverse effect on Wells Fargo's earnings, depending on the
amount of the increase. The FDIC is authorized to terminate a depository
institution's deposit insurance upon a finding by the FDIC that the
institution's financial condition is unsafe or unsound or that the institution
has engaged in unsafe or unsound practices or has violated any applicable rule,
regulation, order or condition enacted or imposed by the institution's
regulatory agency. The termination of deposit insurance for one or more of
Wells Fargo's subsidiary depository institutions could have a material adverse
effect on Wells Fargo's earnings, depending on the collective size of the
particular institutions involved.

  All FDIC-insured depository institutions must pay an annual assessment to
provide funds for the payment of interest on bonds issued by the Financing
Corporation, a federal corporation chartered under the authority of the Federal
Housing Finance Board. The bonds, commonly referred to as FICO bonds, were
issued to capitalize the Federal Savings and Loan Insurance Corporation. The
FDIC established the FICO assessment rates effective for the second quarter of
2000 at approximately $0.21 per $100 annually for BIF-assessable deposits. The
FICO assessments are adjusted quarterly to reflect changes in the assessment
bases of the FDIC insurance funds and do not vary depending on a depository
institution's capitalization or supervisory evaluations.

Fiscal and Monetary Policies

  Wells Fargo's business and earnings are affected significantly by the fiscal
and monetary policies of the federal government and its agencies. Wells Fargo
is particularly affected by the policies of the Federal Reserve Board, which
regulates the supply of money and credit in the United States. Among the
instruments of monetary policy available to the Federal Reserve are:

  .  conducting open market operations in United States government
     securities;

  .  changing the discount rates of borrowings of depository institutions;

  .  imposing or changing reserve requirements against depository
     institutions' deposits; and

  .  imposing or changing reserve requirements against certain borrowing by
     banks and their affiliates.

  These methods are used in varying degrees and combinations to directly affect
the availability of bank loans and deposits, as well as the interest rates
charged on loans and paid on deposits. For that reason alone, the policies of
the Federal Reserve Board have a material effect on the earnings of Wells
Fargo.

Future Legislation

  Various legislation, including proposals to substantially change the
financial institution regulatory system and to expand or contract the powers of
banking institutions and bank holding companies, is from time to time
introduced in the Congress. This legislation may change banking statutes and
the operating environment of Wells Fargo and its subsidiaries in substantial
and unpredictable ways. If enacted, such legislation could increase or decrease
the cost of doing business, limit or expand permissible activities or affect
the competitive balance among banks, savings associations, credit unions, and
other financial institutions. Wells Fargo cannot predict whether any of this
potential legislation will be enacted, and if enacted, the effect that it, or
any implementing regulations, would have on the financial condition or results
of operations of Wells Fargo or any of its subsidiaries.

Wells Fargo Common Stock

  Wells Fargo is authorized to issue 4,000,000,000 shares of common stock, par
value $1 2/3 per share. At March 31, 2000, there were     shares of Wells Fargo
common stock outstanding. All of the issued and outstanding shares of Wells
Fargo common stock are, and upon the issuance of Wells Fargo common stock in
connection with the merger will be, validly issued, fully paid and
nonassessable. Holders of Wells Fargo common stock are not entitled to any
preemptive rights.

  Voting and Other Rights. The holders of Wells Fargo common stock are entitled
to one vote per share, and, in general, a plurality of votes cast with respect
to a matter will be sufficient to authorize action upon routine matters.
However:

  .  Wells Fargo's restated certificate of incorporation may be amended only
     if the proposed amendment is approved by Wells Fargo's board of
     directors and thereafter approved by a majority of the outstanding stock
     entitled to vote on the amendment and by a majority of the outstanding
     stock of each class entitled to vote on the amendment as a class.

  .  Wells Fargo's stockholders may amend its bylaws by the affirmative vote
     of a majority of the outstanding stock entitled to vote thereon.

  .  With some exceptions, under Delaware law the affirmative vote of a
     majority of the outstanding shares of Wells Fargo common stock entitled
     to vote is required to approve a merger or consolidation involving Wells
     Fargo or the sale, lease or exchange of all or substantially all of
     Wells Fargo's corporate assets. See "Comparison of
     Shareholder/Stockholder Rights--Shareholder/Stockholder Vote Required
     for Mergers" for a description of the exceptions to this rule.

  Directors are to be elected by a plurality of the votes cast, and Wells Fargo
stockholders do not have the right to cumulate their votes in the election of
directors. For that reason, holders of a majority of the shares of Wells Fargo
common stock entitled to vote in any election of directors of Wells Fargo may
elect all of the directors standing for election. The Wells Fargo board is not
classified.

                                       46
<PAGE>

  Assets Upon Dissolution. In the event of liquidation, holders of Wells Fargo
common stock would be entitled to receive proportionately any assets legally
available for distribution to stockholders of Wells Fargo with respect to
shares held by them, subject to any prior rights of any Wells Fargo preferred
stock then outstanding.

  Distributions. As a Delaware corporation, Wells Fargo may pay dividends out
of surplus or, if there is no surplus, out of net profits for the fiscal year
in which declared and for the preceding fiscal year. Section 170 of the
Delaware General Corporation Law also provides that dividends may not be paid
out of net profits if, after the payment of the dividend, capital is less than
the capital represented by the outstanding stock of all classes having a
preference upon the distribution of assets.

  As a bank holding company, the ability of Wells Fargo to pay distributions
will be affected by the ability of its banking subsidiaries to pay dividends.
The ability of these banking subsidiaries, as well as of Wells Fargo, to pay
dividends in the future currently is, and could be further, influenced by bank
regulatory requirements and capital guidelines. See "Regulation and Supervision
of Wells Fargo--Dividend Restrictions" for a more detailed description.

  Restrictions on Ownership. The Bank Holding Company Act requires any "bank
holding company" (as defined in the Bank Holding Company Act) to obtain the
approval of the Federal Reserve Board prior to acquiring 5% or more of Wells
Fargo's outstanding common stock. Any person other than a bank holding company
is required to obtain prior approval of the Federal Reserve Board to acquire
10% or more of Wells Fargo's outstanding common stock under the Change in Bank
Control Act. Any holder of 25% or more of Wells Fargo's outstanding common
stock (or a holder of 5% or more if that holder otherwise exercises a
"controlling influence" over Wells Fargo), other than an individual, is subject
to regulation as a bank holding company under the Bank Holding Company Act.

  Preferred Share Purchase Rights. Each issued share of Wells Fargo common
stock includes a Series C Junior Participating Preferred Stock purchase right.
See "--Wells Fargo Rights Plan" below.

Wells Fargo Preferred Stock

  Wells Fargo's restated certificate of incorporation currently authorizes the
issuance of 20,000,000 shares of preferred stock without par value and
4,000,000 shares of preference stock without par value. At March 31, 2000,
there were     shares of Wells Fargo preferred stock outstanding and no shares
of Wells Fargo preference stock outstanding.

  The Wells Fargo board is authorized to issue preferred stock and preference
stock in one or more series, to fix the number of shares in each such series,
and to determine the designations and voting powers, preferences, and relative,
participating, optional or other special rights, and qualifications,
limitations or restrictions of each series. The preferred stock and preference
stock may be issued at any time in any amount, provided that not more than
20,000,000 shares of preferred stock and 4,000,000 shares of preference stock
are outstanding at any one time.

  The Wells Fargo board may determine the designation and number of shares
constituting a series, dividend rates, whether the series is redeemable and the
terms of redemption, liquidation preferences, sinking fund requirements,
conversion privileges, voting rights, as well as other preferences and
relative, participating, optional or other special rights and qualifications,
limitations and restrictions of these special rights, all without any vote or
other action on the part of stockholders.

  The Wells Fargo board has designated 4,000,000 shares of Wells Fargo
preferred stock for issuance as Series C Junior Participating Preferred Stock
under the rights agreement. No shares of Wells Fargo Series C Junior
Participating Preferred Stock are outstanding as of the date of this document.
See "--Wells Fargo Rights Plan" below.


                                       47

Wells Fargo Rights Plan

  On October 21, 1998, Wells Fargo's board of directors declared a dividend of
one Series C Junior Participating Preferred Stock purchase right for each
outstanding share of Wells Fargo common stock. The dividend was paid on
November 23, 1998 to Wells Fargo stockholders of record on that date. Each
right entitles the registered holder to purchase from Wells Fargo one one-
thousandth of a share of Wells Fargo Series C Junior Participating Preferred
Stock, subject to adjustment, at a price of $160 per one one-thousandth of a
share of Wells Fargo Series C Junior Participating Preferred Stock. The
description and terms of the rights are set forth in the rights agreement.

  Until the earlier to occur of (1) ten days following a public announcement
that a person or group of affiliated or associated persons (an "acquiring
person") have acquired beneficial ownership of 15% or more of the outstanding
shares of Wells Fargo common stock or (2) ten business days (or a later date as
may be determined by action of Wells Fargo's board of directors prior to the
time that any person becomes an acquiring person) following the commencement
of, or announcement of an intention to make, a tender offer or exchange offer
the consummation of which would result in the beneficial ownership by a person
or group of 15% or more of the outstanding shares of Wells Fargo common stock
(the earlier of these dates being called the "rights distribution date"), the
rights will be evidenced, with respect to any of the Wells Fargo common stock
certificates outstanding as of November 23, 1998, by a Wells Fargo common stock
certificate with a copy of the summary of rights, attached to the rights
agreement as Exhibit C, attached to the certificate.

  The rights agreement provides that, until the distribution date, the rights
can only be transferred with the shares of Wells Fargo common stock to which
they are attached. Until the distribution date (or earlier redemption or
expiration of the rights), new Wells Fargo common stock certificates issued
after November 23, 1998, upon transfer or new issuance of Wells Fargo common
stock, will contain a notation incorporating the rights agreement by reference.
Until the distribution date (or earlier redemption or expiration of the
rights), the surrender for transfer of any certificates for shares of Wells
Fargo common stock, outstanding as of November 23, 1998, even without this
notation or a copy of the summary of rights being attached to the certificates,
will also constitute the transfer of the rights associated with the shares of
Wells Fargo common stock represented by the certificate. As soon as practicable
following the distribution date, separate certificates evidencing the rights
will be mailed to holders of record of the shares of Wells Fargo common stock
as of the close of business on the distribution date and these separate rights
certificates alone will evidence the rights.

  The rights are not exercisable until the distribution date. The rights will
expire on November 23, 2008, unless that date is extended or unless the rights
are earlier redeemed by Wells Fargo, in each case, as described below.

  The purchase price payable, and the number of shares of Wells Fargo Series C
Junior Participating Preferred Stock or other securities or property issuable,
upon exercise of the rights are subject to adjustment from time to time to
prevent dilution:

  .  in the event of a stock dividend on, or a subdivision, combination or
     reclassification of, the Wells Fargo Series C Junior Participating
     Preferred Stock;

  .  upon the grant to holders of the Wells Fargo Series C Junior
     Participating Preferred Stock of certain rights or warrants to subscribe
     for or purchase Wells Fargo Series C Junior Participating Preferred

  The number of outstanding rights and the number of one one-thousandths of a
share of Wells Fargo Series C Junior Participating Preferred Stock issuable
upon exercise of each right are also subject to adjustment in the event of a
stock split of the shares of Wells Fargo common stock or a stock dividend on
the shares of Wells Fargo common stock payable in shares of Wells Fargo common
stock or subdivisions, consolidations or combinations of the shares of Wells
Fargo common stock occurring, in any such case, prior to the distribution date.

  Wells Fargo Series C Junior Participating Preferred Stock purchasable upon
exercise of the rights will not be redeemable. Each share of Wells Fargo Series
C Junior Participating Preferred Stock will be entitled to a minimum
preferential quarterly dividend payment of $10 per share but will be entitled
to an aggregate dividend of 1000 times the dividend declared per share of Wells
Fargo common stock. In the event of liquidation, the holders of the Wells Fargo
Series C Junior Participating Preferred Stock will be entitled to a minimum
preferential liquidation payment of $1000 per share but will be entitled to an
aggregate payment of 1000 times the payment made per share of Wells Fargo
common stock. Each share of Wells Fargo Series C Junior Participating Preferred
Stock will have 1000 votes, voting together with the shares of Wells Fargo
common stock. Finally, in the event of any merger, consolidation or other
transaction in which shares of Wells Fargo common stock are exchanged, each
share of Wells Fargo Series C Junior Participating Preferred Stock will be
entitled to receive 1000 times the amount received per share of Wells Fargo
common stock. These rights are protected by customary antidilution provisions.

  Because of the nature of the Wells Fargo Series C Junior Participating
Preferred Stock's dividend, liquidation and voting rights, the value of the one
one-thousandth interest in a share of Wells Fargo Series C Junior Participating
Preferred Stock purchasable upon exercise of each right should approximate the
value of one share of Wells Fargo common stock.

  In the event that Wells Fargo is acquired in a merger or other business
combination transaction, or 50% or more of its consolidated assets or earning
power are sold, proper provision will be made so that each holder of a right
will then have the right to receive, upon the exercise of the right at its
then-current exercise price, that number of shares of common stock of the
acquiring company that at the time of such transaction will have a market value
of two times the exercise price of the right. In the event that any person or
group of affiliated or associated persons becomes the beneficial owner of 15%
or more of the outstanding shares of Wells Fargo common stock, proper provision
will be made so that each holder of a right, other than rights beneficially
owned by the acquiring person (which will be void after that time), will then
have the right to receive upon exercise that number of shares of Wells Fargo
common stock having a market value of two times the exercise price of the
right.

  At any time after the acquisition by a person or group of affiliated or
associated persons of beneficial ownership of 15% or more of the outstanding
shares of Wells Fargo common stock, and prior to their acquisition of 50% or
more of the outstanding shares of Wells Fargo common stock, the Wells Fargo
board may exchange the rights (other than rights owned by such person or group
which have become void), in whole or in part, at an exchange ratio of one share
of Wells Fargo common stock, or one one-thousandth of a share of Wells Fargo
Series C Junior Participating Preferred Stock (or of a share of a class or
series of Wells Fargo preferred stock having equivalent rights, preferences and
privileges), per right (subject to adjustment).

  With some exceptions, no adjustment in the purchase price will be required
until cumulative adjustments require an adjustment of at least 1% in the
purchase price. No fractional shares of Wells Fargo Series C Junior
Participating Preferred Stock will be issued, other than fractions which are
integral multiples of one one-thousandth of a share of Wells Fargo Series C
Junior Participating Preferred Stock, which may, at the election of Wells
Fargo, be evidenced by scrip or depositary receipts; and, in lieu of fractional
shares, an adjustment in cash will be made based on the market price of the
Wells Fargo Series C Junior Participating Preferred Stock on the last trading
day prior to the date of exercise.


                                       49
<PAGE>

  At any time prior to the acquisition by a person or group of affiliated or
associated persons of beneficial ownership of 15% or more of the outstanding
shares of Wells Fargo common stock, the Wells Fargo board may redeem the rights
in whole, but not in part, at a price of $.01 per right. The redemption of the
rights may be made effective at the time, on the basis, and with the conditions
that the Wells Fargo board, in its sole discretion, may establish. Immediately
upon any redemption of the rights, the right to exercise the rights will
terminate and the only right of the holders of the rights will be to receive
the redemption price.

  The terms of the rights may be amended by the Wells Fargo board without the
consent of the holders, including an amendment to lower the 15% triggering
thresholds described above to not less than the greater of:

  .  0.001% greater than the largest percentage of the outstanding shares of
     Wells Fargo common stock then known to Wells Fargo to be beneficially
     owned by any person or group of affiliated or associated persons, and

  .  10%.

  However, from and after the time that any person becomes an Acquiring Person,
no amendment may adversely affect the interests of the holders of the rights.
Until a right is exercised, the holder, as such, will have no rights as a
stockholder of Wells Fargo, including, without limitation, the right to vote or
to receive dividends.

  The Rights Have Anti-Takeover Effects. The stockholder rights will cause
substantial dilution to a person or group that attempts to acquire Wells Fargo
on terms not approved by the Wells Fargo board, except by means of an offer
conditioned on a substantial number of rights being acquired. The rights should
not interfere with any merger or other business combination approved by the
Wells Fargo board, as the rights may be redeemed by Wells Fargo at the required
redemption price prior to the time that a person or group has acquired
beneficial ownership of 15% or more of the shares of Wells Fargo common stock.

  The rights agreement, specifying the terms of the rights and including, as an
exhibit, the form of the certificate of designation setting forth the terms of
the Wells Fargo Series C Junior Participating Preferred Stock, is attached as
an exhibit to Wells Fargo's registration statement on Form 8-A, dated October
21, 1998, and is incorporated in this document by reference. The foregoing
description of the Wells Fargo Series C Junior Participating Preferred Stock
purchase rights is qualified in its entirety by reference to this exhibit. See

                  COMPARISON OF SHAREHOLDER/STOCKHOLDER RIGHTS

  The rights of First Commerce shareholders are currently governed by the
Nebraska Business Corporation Act, or NBCA, First Commerce's articles of
incorporation and First Commerce's bylaws. The rights of Wells Fargo
stockholders are currently governed by the Delaware General Corporation Law, or
DGCL, Wells Fargo's restated certificate of incorporation and Wells Fargo's
bylaws. The following is a summary of material differences between the rights
of First Commerce shareholders and the rights of Wells Fargo stockholders. It
is not a complete statement of the provisions affecting, and the differences
between, the rights of First Commerce shareholders and Wells Fargo
stockholders. The summary is qualified in its entirety by reference to the
NBCA, the DGCL, First Commerce's articles of incorporation and bylaws, and
Wells Fargo's restated certificate of incorporation and bylaws.

Cumulative Voting

  Cumulative voting entitles each stockholder to cast an aggregate number of
votes equal to the number of voting shares held, multiplied by the number of
directors to be elected. Each stockholder may cast all of his or her votes for
one nominee or distribute them among two or more nominees, thus permitting
holders of less than a majority of the outstanding shares of voting stock to
achieve board representation. Where cumulative voting is not permitted, holders
of all outstanding shares of voting stock of a corporation elect the entire
board of directors of the corporation, thereby precluding the election of any
directors by the holders of less than a majority of the outstanding shares of
voting stock.

removed if the number of votes
sufficient to elect the director
under cumulative voting is voted
against his or her removal.

Limitations on Directors' Liability

           First Commerce                              Wells Fargo

The NBCA allows the articles of           Wells Fargo's restated certificate
incorporation to eliminate or limit       of incorporation provides that a
the liability of a director to a          director (including an officer who
corporation or its shareholders from      is also a director) of Wells Fargo
monetary damages for any action           shall not be liable personally to
taken as a director, except for:          Wells Fargo or its stockholders for
                                          monetary damages for breach of

  not entitled;                           . any breach of the director's duty

                                            of Section 174 of the DGCL; or

                                          This provision protects Wells
                                          Fargo's directors against personal
                                          liability for monetary damages from
                                          breaches of their duty of care. It
                                          does not eliminate the director's
                                          duty of care and has no effect on
                                          the availability of equitable
                                          remedies, such as an injunction or
                                          rescission, based upon a director's
                                          breach of his or her duty of care.

  The timing and amount of future dividends will depend on earnings, cash
requirements, the financial condition of Wells Fargo and its subsidiaries,
applicable government regulations and other factors deemed relevant by Wells
Fargo's board of directors in its discretion. As described in "Regulation And
Supervision Of Wells Fargo--Dividend Restrictions," various federal and state
laws limit the ability of affiliate banks to pay dividends to Wells Fargo.

                           FORWARD-LOOKING STATEMENTS

  This document, including information incorporated by reference into this
document, may contain forward-looking statements about Wells Fargo and First
Commerce, including one or more of the following:

  .  projections of revenues, income, earnings per share, capital
     expenditures, dividends, capital structure or other financial items;

  .  descriptions of plans or objectives of management for future operations,
     products or services;

  .  forecasts of future economic performance;

  .  descriptions of assumptions underlying or relating to any of the
     foregoing.

  Forward-looking statements can be identified by the fact that they do not
relate strictly to historical or current facts. They often include words such
as "believe," "expect," "anticipate," "intend," "plan," "estimate," or words of
similar meaning, or future or conditional verbs such as "will," "would,"
"should," "could" or "may."

  Forward-looking statements consist of expectations or predictions of future
conditions, events or results. They are not guarantees of future performance.
By their nature, forward-looking statements are subject to risks and
uncertainties. There are a number of factors--many of which are beyond the
control of Wells Fargo and First Commerce--that could cause actual conditions,
events or results to differ significantly from those described in the forward-
looking statements.

  Wells Fargo's and First Commerce's reports filed with the SEC, including
Wells Fargo's and First Commerce's Forms 10-K for the year ended December 31,
1999, describe some of these factors. For example, Wells Fargo's Form 10-K
describes certain credit, market, operational, liquidity and interest rate
risks associated with Wells Fargo's business and operations. Other factors
described in Wells Fargo's Form 10-K include changes in business and economic
conditions, competition, fiscal and monetary policies, disintermediation,
legislation (including financial modernization legislation), the combination of
the former Norwest Corporation and the former Wells Fargo & Company, and other
mergers and acquisitions.

  There are other factors besides these that could cause actual conditions,
events or results to differ significantly from those described in the forward-
looking statements or otherwise affect in the future Wells Fargo's and/or First
Commerce's business, results of operations and financial condition.

                              AMENDED AND RESTATED
                      AGREEMENT AND PLAN OF REORGANIZATION

  AGREEMENT AND PLAN OF REORGANIZATION (the "Agreement") entered into as of the
1st day of February, 2000, and amended and restated as of April 14, 2000, but

Fargo"), a Delaware corporation, and First National Bank and Trust Co. of
Kearney, The Overland National Bank of Grand Island, Western Nebraska National
Bank, and The First National Bank of West Point.

  WHEREAS, the parties hereto desire to effect a reorganization whereby a
wholly-owned subsidiary of Wells Fargo 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 Class A Voting Common Stock
of Company of the par value of $.20 per share ("Class A Stock") and shares of
the Company's Class B Non-Voting Common Stock of the par value of $.20 per
share ("Class B Stock") (collectively, "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, if necessary to provide Wells Fargo with
ownership, directly or indirectly, of 100% of the outstanding Bank Common Stock
after the Merger, immediately following the Merger, Wells Fargo will contribute
its newly formed, wholly-owned bank subsidiaries (collectively, "Wells Fargo
Banks") to Company and, immediately thereafter, one of the Wells Fargo Banks
will consolidate with each of First National Bank and Trust Co. of Kearney, The
Overland National Bank of Grand Island, Western Nebraska National Bank, and The
First National Bank of West Point (collectively referred to as the "Banks")
(each a "Consolidation" and collectively, the "Consolidations") pursuant to
agreements of consolidation (each a "Consolidation Agreement" and collectively,
the "Consolidation Agreements") in substantially the form attached hereto as
Exhibit A-2, which provides, among other things, for the conversion of the
shares of voting common stock of the Banks outstanding immediately prior to the
time the Consolidations become effective in accordance with the provisions of
the applicable Consolidation Agreement and owned by shareholders other than
Company (collectively and individually, "Bank Common Stock") into the right to
receive an amount in cash set forth on Schedule 1(a)(ii); and

  WHEREAS, in connection with the execution and delivery of this Agreement,
certain significant shareholders, directors, and executive officers of the
Company are entering into agreements with Wells Fargo (the "Support
Agreements") pursuant to which they shall agree to vote all of the shares of
Company Common Stock owned by them in favor of the Merger; and

  WHEREAS, this Agreement, the Merger Agreement and Consolidation Agreements
are hereafter sometimes referred to collectively as the "Transaction
Agreements" and the Merger and Consolidations are hereafter sometimes referred
to collectively as the "Transactions."

  NOW, THEREFORE, to effect such reorganization and in consideration of the
promises 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) Transactions.

  (i) Merger. Subject to the terms and conditions contained herein, a wholly-
owned subsidiary of Wells Fargo (the "Merger Co.") will be merged by statutory
merger with and into Company pursuant to the Merger

                                      A-1
<PAGE>

Agreement, with Company as the surviving corporation (the "Surviving
Corporation"), in which Merger (A) each share of Class A Stock and Class B
Stock outstanding immediately prior to the Effective Time of the Merger (as
defined in paragraph 1(d) below) (other than shares of Company Common Stock
owned, directly or indirectly, by Wells Fargo or the Company (other than shares
of Company Common Stock held, directly or indirectly, in trust accounts,
managed accounts and the like, or otherwise held in a fiduciary capacity, that
are beneficially owned by third parties ("Trust Account Shares"), and any
shares of Company Common Stock held by the Company or Wells Fargo or any of
their respective subsidiaries in respect of a debt previously contracted ("DPC
Shares")) will be converted into the right to receive a number of shares of
Wells Fargo Common Stock equal to $35.95 divided by the Wells Fargo Measurement
Price.

  (ii) Consolidation. Following the Effective Time of the Merger and on the
terms and conditions contained herein, Wells Fargo will, to the extent
necessary to provide Wells Fargo with ownership, directly or indirectly, or
100% of the outstanding Bank Common Stock, contribute five interim national
associations to Company and, immediately thereafter, each will be consolidated
with one of the Banks under the charter of such Bank pursuant to a
Consolidation Agreement, in which Consolidation each share of such Bank's
Common Stock outstanding immediately prior to the Effective Time of such
Consolidation (other than shares owned by the Surviving Corporation, shares as
to which statutory dissenters' appraisal rights have been exercised, and
directors qualifying "Shares Subject to Buy-Back Agreements" (as defined in
paragraph 2(b))) will be converted into the right to receive an amount in cash
as set forth in Schedule 1(a)(ii).

  (iii) Wells Fargo Measurement Price. The Wells Fargo Measurement Price is
defined as the average of the closing prices of a share of Wells Fargo Common
Stock as reported on the consolidated tape of the New York Stock Exchange
during the period of twenty (20) trading days ending on the day immediately
preceding the date of the shareholders' meeting to consider the Merger as
contemplated by paragraph 4(c).

    (b) Wells Fargo Common Stock Adjustments. If, between the date hereof and
  the Effective Time of the Merger, shares of Wells Fargo Common Stock shall
  be changed into a 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 for
  which a share of Company Common Stock shall be exchanged pursuant to
  subparagraph (a), above, will be appropriately and proportionately adjusted
  so that the number of such shares of Wells Fargo Common Stock for which a
  share of Company Common Stock shall be exchanged 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.

    (c) 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 as reported by
  the consolidated tape of the New York Stock Exchange for each of the five
  (5) trading days ending on the second day immediately preceding the
  Effective Date of the Merger (as defined in paragraph 1(d) of this
  Agreement).

    (d) Treasury Shares. At the Effective Time, all shares of Company Common
  Stock owned, directly or indirectly, by the Company or by Wells Fargo,
  other than Trust Account Shares or DPC Shares, shall be canceled and shall
  cease to exist, and no capital stock of Wells Fargo or other consideration
  shall be delivered in exchange therefor.

    (e) Mechanics of Closing Merger. Subject to the terms and conditions set
  forth herein:

      (i) The Merger Agreement shall be executed and it or Articles of
    Merger shall be filed with the Secretary of State of the State of
    Nebraska within five (5) business days following the satisfaction or

                                      A-2
<PAGE>

    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. Lincoln, Nebraska 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.

      (ii) The Consolidations shall become effective at the time specified
    in the applicable Consolidation Agreement (each, the "Effective Time of
    the Consolidation") on the date specified in the Certificate of
    Approval of Merger to be issued by the Office of the Comptroller of the
    Currency ("Comptroller"), which date shall be the first business day
    after the Effective Date of the Merger (the "Effective Date of the
    Consolidation").

    The closing of the Transactions contemplated by this Agreement and the
  Merger Agreement and the Consolidation Agreements (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 may alternatively be structured so that (1) Company is merged
  with and into 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 (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 the Company's stockholders
  in the Merger or the Banks' respective stockholders pursuant to Section
  1(a), (B) adversely affect the tax treatment of Company's stockholders as a
  result of receiving the Consideration or prevent the parties from obtaining
  the opinion referred to in paragraph 6(h), or (C) impede or delay
  consummation of the Merger or the Consolidations. 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. Except as set forth in the
Company disclosure schedules to this Agreement, Company represents and warrants
to Wells Fargo as follows:

  (a) Organization and Authority. Company is a corporation duly incorporated,
validly existing and in good standing under the laws of the State of Nebraska,
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 with respect to Company and has corporate power and
authority to own its properties and assets and to carry on its business as it
is now being conducted. "Material Adverse Effect" with respect to Wells Fargo
or Company, as the case may be, means any fact, circumstance, event, or thing
that (1) has a material adverse effect on the business, financial position, or
results of operations of such party and its subsidiaries, taken as a whole
(other than to the extent such fact, circumstance, event, or thing is due to
(x) general changes in conditions, including interest rates, in the banking
industry or in the global or United States economy or financial markets or (y)
changes in applicable generally accepted accounting principles or in laws,
regulations, or regulatory policies of general applicability) or (2) prevents
consummation by such party of, or materially impedes the ability of such party
to consummate, the transactions contemplated by this Agreement. Company is
registered as a bank holding company with the Board of Governors of the Federal
Reserve System (the "Federal Reserve Board") under the Bank Holding Company Act
of 1956, as amended (the "BHC Act"). Company has furnished Wells Fargo true and
correct copies of its articles of incorporation and by-laws, as amended.


                                      A-3
<PAGE>

  (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. Except as set forth
on Schedule 2(b), all shares of any Company Subsidiary not owned directly or
indirectly by Company constitute directors qualifying shares which such Company
Subsidiary may repurchase at book value pursuant to buy-back or redemption
agreements, true and correct copies of which have previously been provided to
Wells Fargo ("Shares Subject to Buy-Back Agreements"). 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 12 U.S.C. (S) 55 (1982) and the Nebraska Business
Corporation 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 national 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
50,000,000 shares of common stock, $.20 par value, consisting of 10,000,000
shares of Class A Voting Common Stock, $.20 par value, and 40,000,000 shares of
Class B Non-Voting Common Stock, $.20 par value, of which, as of the close of
business on September 30, 1999, 2,568,892 shares of Class A Stock and
10,775,394 of Class B Stock were outstanding and no shares of Class A Stock and
no shares of Class B Stock were held in the treasury. 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
13,344,286. 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 in Schedule 2(c), there are no outstanding subscriptions,
contracts, conversion privileges, options, warrants, calls, 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. Except as set forth in
Schedule 2(c) and for the regular quarterly dividends paid or payable with
respect to the Company Common Stock, since September 30, 1999 no shares of
Company capital stock have been purchased, redeemed or otherwise acquired,
directly or indirectly, by Company or any Company Subsidiary and no dividends
or other distributions have been declared, set aside, made or paid to the
stockholders of Company.

  (d) Authorization. Company has, and each Bank upon execution of the
Consolidation Agreement will have, the corporate power and authority to enter
into this Agreement and the Merger Agreement and the Consolidation Agreements,
as applicable, and, subject to any required approvals of its stockholders, to
carry out its obligations hereunder and thereunder. The execution, delivery and
performance of this Agreement and the Merger Agreement by Company and of the
Consolidation Agreements by the Banks, as the case may be, and the consummation
of the transactions contemplated hereby and thereby have been (and, in the case
of the Banks, will be) duly authorized by the Board of Directors of Company and
Banks, as applicable. Subject to such approvals of stockholders and of
government agencies and other governing boards having regulatory authority over
Company as may be required by statute or regulation, this Agreement and the
Merger Agreement and the Consolidation Agreements are (and, in the case of the
Banks, will be if and when entered into pursuant hereto) valid and binding
obligations of Company and Banks, as the case may be, enforceable against them
in accordance with their respective terms.

Except as set forth on Schedule 2(d), neither the execution, delivery and
performance by Company of this Agreement or the Merger Agreement and of the
Consolidation Agreements by the Banks, as the case may be, nor the consummation
of the transactions contemplated hereby and thereby, nor compliance by Company
and Banks with any of the provisions hereof or thereof, will (i) violate,
conflict with, or result in a breach of any provision of, or constitute a
default (or an event which, with notice or lapse of time or both, would
constitute a default) under, or result in the termination of, or accelerate the
performance required by, or result in a right of termination or acceleration
of, or result in the creation of, any lien, security interest, charge or
encumbrance upon any of the properties or assets of Company or any Company
Subsidiary under any of the terms, conditions or provisions of (x) its articles
of incorporation, articles of association, or by-laws or (y) any material note,
bond, mortgage, indenture, deed of trust, license, lease, agreement or other
instrument or obligation to which Company or any Company Subsidiary is a party
or by which it may be bound, or to which Company or any Company Subsidiary or
any of the properties or assets of Company or any Company Subsidiary may be
subject, or (ii) subject to compliance with the statutes and regulations
referred to in the next paragraph, violate any statute, rule or regulation or,
to the best knowledge of Company, violate any judgment, ruling, order, writ,
injunction or decree applicable to Company or any Company Subsidiary or any of
their respective properties or assets.

regulations thereunder (the "Exchange Act"), the securities or blue sky laws of

accounting principles applied on a consistent basis (except as may be indicated

  (g) Properties and Leases. Except as may be reflected in the Company
Financial Statements and except for any lien for current taxes not yet

of any material liens, claims, charges, options, encumbrances or similar
restrictions to all the real and personal property reflected in Company's
consolidated balance sheet as of September 30, 1999 included in Company's
Quarterly Report on Form 10-Q, 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.

taxes owed by it, including 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

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 to the
knowledge of Company 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 or accrued 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 September 30,
1999, referred to in paragraph 2(e) hereof, includes adequate provision for all
accrued but unpaid federal, state, county, local and foreign taxes, interest,

  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);

    (ii) any plan, contract or understanding providing for any bonus,
  pension, option, deferred compensation, retention payment, retirement

<PAGE>

  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;

    (vi) any real property lease and any other lease with annual rental
  payments aggregating $25,000 or more;

  providing for any rights of indemnification in favor of such person or
  entity.

  (k) Litigation and Other Proceedings. Company has furnished Wells Fargo

through the date hereof, 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 with respect to Company.

  (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. Each of Company and each Company Subsidiary has all
permits, licenses, authorizations, orders and approvals of, and has made all
filings, applications and registrations with, federal, state, local or foreign
governmental or regulatory bodies that are required in order to permit it to
own or lease its properties and assets and to carry on its business as
presently conducted and that are material to the business of Company or such
Company Subsidiary; all such permits, licenses, certificates of authority,
orders and approvals are in full force and effect and, to the best knowledge of
Company, no suspension or cancellation of any of them is threatened; and all
such filings, applications and registrations are current. The conduct by
Company and each such Company Subsidiary of its business and the condition and
use of its properties do 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 such
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
with respect to Company.

  (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 would
reasonably be expected to have a Material Adverse Effect with respect to
Company. 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

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

  (p) Company Benefit Plans.

    (i) Schedule 2(p)(i) sets forth each employee benefit plan with respect
  to which Company or any Company Subsidiary contributes to or sponsors (the
  "Plans"). For purposes of this Section 2(p) and Schedule 2(p)(i), "ERISA"
  means the Employee Retirement Income Security Act of 1974, as amended, and
  the term "Plan" or "Plans" means all employee benefit plans as defined in

  disability benefits, supplemental unemployment benefits, vacation benefits,
  retirement benefits, severance or termination of employment benefits, life,
  health, death, disability or accidental benefits.

  law including, if applicable, ERISA and the Code; (b) all reports and
  filings with governmental agencies (including but not limited to the

  notices required by law or Plan provisions to be given to participants and

  Plan intended to be qualified under Section 401(a) of the Code has received
  a favorable determination letter from the Internal Revenue Service stating
  that the Plan (including all amendments to the extent such amended
  provisions have been required to be submitted to the Internal Revenue
  Service for a determination letter as of the date of this Agreement) 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.

<PAGE>

  contribution was made (whether under Sections 162, 280G, 404, 419, 419A of
  the Code or otherwise); and (d) with respect to each Plan that is subject
  to Section 301 of ERISA or Section 412 of the Code, Company is not liable
  for any accumulated funding deficiency as that term is defined in Section
  412 of the Code and the projected benefit obligations determined as of the
  date of this Agreement do not exceed the assets of the Plan.

    (vi) Except as disclosed in 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 that would reasonably be expected to result in a
  Material Adverse Effect with respect to Company.

    (vii) No Plan subject to Title IV of ERISA or any trust created
  thereunder has been terminated, nor have there been any "reportable events"

    (viii) Except as disclosed in Schedule 2(p)(viii), neither the execution
  and delivery of this Agreement and the Merger Agreement nor the

  any director or employee or former employee of Company under any Plan or
  otherwise, (b) materially increase any benefits otherwise payable under any
  Plan, or (c) result in the acceleration of the time of payment or vesting

Agreements 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

commissions or finder's fees, and no broker or finder has acted

                                      A-9
<PAGE>

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. Except as would not reasonably be expected to have
a Material Adverse Effect with respect to Company, Company and each Company
Subsidiary has properly administered 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. Except as would
not reasonably be expected to have a Material Adverse Effect with respect to
Company, neither Company, any Company Subsidiary, nor any director, officer or
employee of Company or any Company Subsidiary has committed any breach of trust
with respect to any such fiduciary account, and the accountings for each such
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, or both, would constitute a default, under any material agreement,
indenture, loan agreement or other instrument to which it is a party or by
which it or any 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 with respect to Company. 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.

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 would reasonably be expected to have
a Material Adverse Effect with respect to Company; except as set forth in
Schedule 2(v), 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

pending action or proceeding, nor to Wells Fargo's knowledge is any such action
or proceeding threatened by any governmental authority, for the assessment or

could reasonably be expected to have any Material Adverse Effect with respect
to Wells Fargo, 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

December 31, 1998 neither Wells Fargo nor any Wells Fargo Subsidiary is a party
or subject to any of the following (whether written or oral, express or
implied):

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

    (ii)  any contract not made in the ordinary course of business containing
  covenants which materially limit the ability of Wells Fargo or any Wells
  Fargo Subsidiary to compete in any line of business or with any person or
  which involve any material restriction of the 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 required by law or applicable regulatory
  authorities);

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

  (k) Litigation and Other Proceedings. There is no pending or, to the best
knowledge of Wells Fargo, threatened, claim, action, suit, investigation or
proceeding, against Wells Fargo or any Wells Fargo Subsidiary nor is Wells
Fargo or any Wells Fargo Subsidiary subject to any order, judgment or decree,
except for matters

                                      A-13
<PAGE>

which, in the aggregate, will not have, or cannot reasonably be expected to
have, a Material Adverse Effect with respect to Wells Fargo.

  (l) Insurance. Wells Fargo and each Wells Fargo Subsidiary is presently
insured or self insured, and during each of the past five calendar years (or
during such lesser period of time as Wells Fargo has owned such Wells Fargo
Subsidiary) has been insured or self-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. Wells Fargo and each Wells Fargo Subsidiary has all
permits, licenses, authorizations, orders and approvals of, and has made all
filings, applications and registrations with, federal, state, local or foreign
governmental or regulatory bodies that are required in order to permit it to
own or lease its properties or assets and to carry on its business as presently
conducted and that are material to the business of Wells Fargo or such Wells
Fargo Subsidiary; all such permits, licenses, certificates of authority, orders
and approvals are in full force and effect, and to the best knowledge of Wells
Fargo, no suspension or cancellation of any of them is threatened; and all such
filings, applications and registrations are current. The conduct by Wells Fargo
and each Wells Fargo 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 Wells Fargo nor any
Wells Fargo 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, no federal, state,
municipal or other governmental authority has placed any restrictions on the
business or properties of Wells Fargo or any Wells Fargo Subsidiary which
reasonably could be expected to have a Material Adverse Effect with respect to
Wells Fargo.

  any obligations.

    (ii) No Wells Fargo Plan is a "multiemployer plan" within the meaning of

  of the Code has received a favorable determination letter from the Internal
  Revenue Service stating that the Wells Fargo Plan (including all
  amendments) is tax qualified under Section 401(a) of the Code and Wells
  Fargo knows of 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 related Wells Fargo Plan trust is not exempt from taxation under
  Section 501(a) of the Code.

  recent Plan Year.

  (p) Registration Statement, etc. None of the information regarding Wells
Fargo and its subsidiaries supplied or to be supplied by Wells Fargo for
inclusion in (i) the Registration Statement, (ii) the Proxy Statement, or (iii)
any other documents to be filed with the SEC or any regulatory authority in
connection with the transactions contemplated hereby or by the 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

local, state or federal environmental statute, regulation or ordinance
including, without limitation, CERCLA, pending or to the best of Wells Fargo's
knowledge, threatened against Wells Fargo or any Wells Fargo Subsidiary, the

Adverse Effect with respect to Wells Fargo; to the best of Wells Fargo's
knowledge, there is no reasonable basis for any such proceeding, claim or
action; and to the best of Wells Fargo's knowledge, neither Wells Fargo nor any

                                      A-18

outside professional advisers in connection with this Agreement, with the same
undertaking from such professional advisers. If the transactions contemplated
by this Agreement shall not be consummated, such confidence shall be maintained
and such information shall not be used in competition with Company (except to
the extent that such information can be shown to be previously known to Wells

    (i) Wells Fargo shall ensure that all rights to indemnification and all
  limitations of liability existing in favor of 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"), in Company's Articles of Incorporation or By-laws
  or similar governing documents of any Company Subsidiary, as applicable in
  the particular case and as in effect on the date hereof, shall, with
  respect to claims arising from (A) facts or events that occurred before the
  Effective Time of the Merger, or (B) this Agreement, the Merger Agreement,
  the Consolidation Agreements, and the Support Agreements or any of the
  transactions contemplated hereby or thereby, whether in any case asserted
  or arising before or after the Effective Time of the Merger, survive

                                      A-21
<PAGE>

  the Merger and shall continue in full force and effect. 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 greater of the net asset
  value of Company as of the Effective Date of the Merger or as of the date
  of such liquidation or sale, the indemnification obligations of Company or
  any Company Subsidiary to the extent of indemnification obligations of
  Company and the Company Subsidiaries described above. Each Indemnified
  Party shall have the right to assert claims for indemnification directly
  against Wells Fargo without first having to assert such claim against
  Company or any Company Subsidiary. 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 from the Effective Time, Wells Fargo
  shall use its reasonable 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 the Company or any Company Subsidiary with
  respect to claims against such directors and officers arising from facts or
  events that 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 the
  Company; provided however, that in no event shall Wells Fargo be required
  to expend more than 200% of the current amount expended by the Company
  (such limit on the premiums required to be expended by Wells Fargo, the
  "Insurance Amount") to maintain or procure such director's and officer's
  insurance coverage for a comparable six-year period; provided further, that
  if Wells Fargo is unable to maintain or obtain the insurance called for by
  this Section 5(m)(iii), Wells Fargo shall use its reasonable best efforts
  to obtain as much comparable insurance as is available for the Insurance
  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 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.

  SIXTH: The manner and basis of converting the shares of FCBI Common Stock
shall be as follows:

    1. Subject to the terms and conditions contained herein, Wells FCBI

  Stock and Class B Stock outstanding immediately prior to the effective time
  of the merger (other than shares of FCBI Common Stock owned, directly or
  indirectly, by Wells Fargo or FCBI (other than shares of FCBI Common Stock
  held, directly or indirectly, in trust accounts, managed accounts and the
  like, or otherwise held in a fiduciary capacity, that are beneficially
  owned by third parties), and any shares of FCBI Common Stock held by FCBI
  or Wells Fargo or any of their respective subsidiaries in respect of a debt
  previously contracted) will be converted into the right to receive, subject
  to paragraph 4 of this Article Sixth, a number of shares of Wells Fargo
  Common Stock equal to $35.95 divided by the Wells Fargo Measurement Price.
  The Wells Fargo Measurement Price is defined as the average of the closing
  prices of a share of Wells Fargo Common Stock as reported on the
  consolidated tape of the New York Stock Exchange during the period of
  twenty (20) trading days ending on the day immediately preceding the date
  of the shareholders' meeting to consider the merger contemplated hereby.

                                     A-1-2
<PAGE>

    2. As soon as practicable after the merger becomes effective, each holder
  of a certificate which, prior to the effective time of the merger,
  represented shares of FCBI Common Stock outstanding immediately prior to
  the time of merger (other than shares of FCBI Common Stock owned, directly
  or indirectly, by Wells Fargo or FCBI (other than shares of FCBI Common
  Stock held, directly or indirectly, in trust accounts, managed accounts and
  the like, or otherwise held in a fiduciary capacity, that are beneficially
  owned by third parties, and any shares of FCBI Common Stock held by FCBI or
  Wells Fargo or any of their respective subsidiaries in respect of a debt
  previously contracted) shall be entitled, upon surrender of such
  certificate representing a share of FCBI Common Stock for cancellation to
  the surviving corporation or to Norwest Bank Minnesota, National
  Association, as the designated agent of the surviving corporation (the
  "Agent"), to receive a new certificate representing the number of whole
  shares of Wells Fargo Common Stock and cash in lieu of fractional shares to
  which such holder shall be entitled on the basis set forth in paragraphs 1
  and 4 of this Article Sixth. Until so surrendered each certificate which,
  immediately prior to the time of merger, represented shares of FCBI Common
  Stock shall not be transferable on the books of the surviving corporation
  but shall be deemed to evidence only the right to receive (except for the
  payment of dividends as provided below) the number of whole shares of Wells
  Fargo Common Stock issuable and cash in lieu of fractional shares payable
  on the basis above set forth; provided, however, until the holder of such
  certificate for FCBI Common Stock shall have surrendered the same as above
  set forth, no dividend payable to holders of record of Wells Fargo Common
  Stock as of any date subsequent to the effective date of merger shall be
  paid to such holder with respect to the shares of Wells Fargo Common Stock,
  if any, issuable in connection with the merger, but, upon surrender and
  exchange thereof as herein provided, there shall be paid by the surviving
  corporation or the Agent to the record holder of such certificate
  representing Wells Fargo Common Stock issued in exchange therefor an amount
  with respect to such shares of Wells Fargo Common Stock equal to all
  dividends that shall have been paid or become payable to holders of record
  of Wells Fargo Common Stock between the effective date of merger and the
  date of such exchange.

    3. If, between the date hereof and the time of merger, shares of Wells
  Fargo Common Stock shall be changed into a 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, then the number of shares of Wells Fargo
  Common Stock, if any, into which a share of FCBI Common Stock shall be
  exchangeable on the basis above set forth, will be appropriately and
  proportionately adjusted so that the number of such shares of Wells Fargo
  Common Stock into which a share of FCBI Common Stock shall be exchanged
  will equal the number of shares of Wells Fargo Common Stock which the
  holders of shares of FCBI Common Stock would have received pursuant to such
  reclassification, recapitalization, split-up, combination, exchange of
  shares or readjustment, or stock dividend had the record date therefor been
  immediately following the time of merger.

    4. 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 of a fractional interest 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 as reported by
  the consolidated tape of the New York Stock Exchange for each of the five
  (5) trading days ending on the second day immediately preceding the
  effective date of the merger.

    5. Each share of Wells FCBI Merger Co. Common Stock issued and
  outstanding at the time of merger shall be converted into and exchanged for
  one (1) share of the surviving corporation after the time of merger.

  SEVENTH: The merger provided for by this Agreement shall be effective as

Board of Directors
First Commerce Bancshares, Inc.
1248 O Street
Lincoln, NE 68508

Members of the Board:

  We understand that First Commerce Bancshares, Inc. ("First Commerce") and
Wells Fargo & Company ("Wells Fargo") propose to enter into an Agreement and
Plan of Reorganization, dated as of February 1, 2000 (the "Merger Agreement"),
pursuant to which a subsidiary of Wells Fargo is to be merged with and into
First Commerce, with First Commerce being the surviving corporation (the
"Merger"). Pursuant to the Merger, and as set forth more fully in the Merger
Agreement, each outstanding share of Class A Voting Common Stock, par value
$0.20 per share, of First Commerce and each outstanding share of Class B Non-
Voting Common Stock, par value $0.20 per share, of First Commerce
(collectively, the "First Commerce Shares"), will be converted into the right
to receive that number of shares (the "Merger Consideration") of the voting
common stock of Wells Fargo, par value $1-2/3 per share, (the "Wells Fargo
Shares") equal to $35.95 divided by the Wells Fargo Measurement Price (as
defined in the Merger Agreement).

  You have asked us whether, in our opinion, the Merger Consideration is fair
to the shareholders of First Commerce from a financial point of view.

  In arriving at the opinion set forth below, we have, among other things:

  (1) Reviewed certain publicly available business and financial information
      relating to First Commerce and Wells Fargo that we deemed to be
      relevant;

  (2) Reviewed certain information, including financial forecasts, relating
      to the respective business, earnings, assets, liabilities and prospects
      of First Commerce furnished to us by senior management of First
      Commerce;

  (3) Conducted discussions with members of senior management and
      representatives of First Commerce and Wells Fargo concerning the
      matters described in (1) and (2) above, as well as their respective
      businesses and prospects before and after giving effect to the Merger;

  (4) Reviewed the market prices and valuation multiples for the First
      Commerce Shares and the Wells Fargo Shares and compared them with those
      of certain publicly traded companies that we deemed to be relevant;

  (5) Reviewed the respective publicly reported financial condition and
      results of operations of First Commerce and Wells Fargo and compared
      them with those of certain publicly traded companies that we deemed to
      be relevant;

  (6) Compared the proposed financial terms of the Merger with the financial
      terms of certain other transactions that we deemed to be relevant;

  (7) Participated in certain discussions and negotiations among
      representatives of First Commerce and Wells Fargo and their financial
      and legal advisors with respect to the Merger;

  (8) Reviewed the most recent draft of the Merger Agreement provided to us;
      and

  (9) Reviewed such other financial studies and analyses and took into
      account such other matters as we deemed necessary, including our
      assessment of general economic, market and monetary conditions.

  In preparing our opinion, we have assumed and relied on the accuracy and
completeness of all information supplied or otherwise made available to us,
discussed with or reviewed by or for us, or publicly available, and we have not
assumed any responsibility for independently verifying such information or
undertaken an independent evaluation or appraisal of the assets or liabilities
of First Commerce or Wells Fargo or been furnished with any such

                                      B-1
<PAGE>

evaluation or appraisal. We are not experts in the evaluation of allowances for
loan losses, and we have neither made an independent evaluation of the adequacy
of the allowances for loan losses of First Commerce or Wells Fargo, nor have we
reviewed any individual credit files of First Commerce or Wells Fargo or been
requested to conduct such a review, and, as a result, we have assumed that the
respective allowances for loan losses for First Commerce and Wells Fargo are
adequate to cover such losses and will be adequate on a pro forma basis for the
combined entity. In addition, we have not assumed any obligation to conduct,
nor have we conducted any physical inspection of the properties or facilities
of First Commerce or Wells Fargo. With respect to the financial and operating
information, including without limitation, financial forecasts, valuations of
contingencies and projections regarding under-performing and non-performing
assets, net charge-offs, adequacy of reserves, future economic conditions,
furnished to or discussed with us by First Commerce or Wells Fargo, we have
assumed that they have been reasonably prepared and reflect the best currently
available estimates and judgments of the senior management of First Commerce
and Wells Fargo as to the future financial and operating performance of First
Commerce, Wells Fargo or the combined entity, as the case may be.

  Our opinion is necessarily based upon market, economic and other conditions
as in effect on, and on the information made available to us as of, the date
hereof. For the purposes of rendering this opinion, we have assumed that the
Merger will be consummated substantially in accordance with the terms set forth
in the Merger Agreement, including in all respects material to our analysis,
that the representations and warranties of each party in the Merger Agreement
and in all related documents and instruments (collectively, the "Documents")
that are referred to therein are true and correct, that each party to the
Documents will perform all of the covenants and agreements required to be
performed by such party under such Documents, that all conditions to the
consummation of the Merger will be satisfied without waiver thereof, and that
the final form of the Merger Agreement and the Documents will be substantially
similar to the most recent drafts provided to us. We have also assumed that, in
the course of obtaining the necessary regulatory or other consents or approvals
(contractual or otherwise) for the Merger, no restrictions, including any
divestiture requirements, termination or other payments or amendments or
modifications, will be imposed that will have a material adverse effect on the
future results of operations or financial condition of First Commerce, Wells
Fargo or the combined entity, as the case may be, or on the contemplated
benefits of the Merger.

  We have been retained by the Board of Directors of First Commerce to act as
financial advisor to First Commerce in connection with the Merger and will
receive a fee from First Commerce for our services, a significant portion of
which is contingent upon the consummation of the Merger. In addition, First
Commerce has agreed to indemnify us for certain liabilities arising out of our
engagement. We have in the past provided financial advisory, investment banking
and other services to Wells Fargo and have received fees for the rendering of
such services, and we may continue to provide such services in the future. In
the ordinary course of our business, we also may actively trade the First
Commerce Shares and other securities of First Commerce and its affiliates and
the Wells Fargo Shares and other securities of Wells Fargo and its affiliates
for our own account and for the accounts of our customers, and, accordingly,
may at any time hold long or short positions in such securities.

  This opinion is for the sole and exclusive use and benefit of the Board of
Directors of First Commerce. It is further understood that this opinion will
not be reproduced, summarized, described or referred to or given to any person
without Merrill Lynch's prior written consent. Our opinion does not address the
merits of the underlying decision by First Commerce to engage in the Merger and
does not constitute a recommendation to any shareholder of First Commerce as to
how such shareholder should vote on the proposed Merger or any other matter
related thereto.

  We have not considered, nor are we expressing any opinion herein with respect
to, the prices at which First Commerce Shares or Wells Fargo Shares will trade
following the announcement of the Merger or the price at which the Wells Fargo
Shares will trade following the consummation of the Merger.

  On the basis of and subject to the foregoing, we are of the opinion that, as
of the date hereof, the Merger Consideration is fair to shareholders of First
Commerce from a financial point of view.

                                    Very truly yours,


                                      B-2

                                    PART II

                   INFORMATION NOT REQUIRED IN THE PROSPECTUS

Item 20. Indemnification of Directors and Officers.

  Section 145 of the Delaware General Corporation Law authorizes
indemnification of directors and officers of a Delaware corporation under
certain circumstances against expenses, judgments and the like in connection
with an action, suit or proceeding. Article Fourteenth of the Registrant's
Restated Certificate of Incorporation provides for broad indemnification of
directors and officers.

Item 21. Exhibits and Financial Statement Schedules.

  (a) Exhibits. See Exhibit Index.

  (b) Financial Statement Schedules. Not Applicable.

  (c) Report, Opinion or Appraisal. See Exhibits 5.1 and 8.1.

Item 22. Undertakings.

  (a) The undersigned registrant hereby undertakes:

  (1) To file, during any period in which offers or sales are being made, a
posteffective amendment to this registration statement:

  (i) To include any prospectus required by section 10(a)(3) of the Securities
Act of 1933.

  (ii) To reflect in the prospectus any facts or events arising after the
effective date of the registration statement (or the most recent post-effective
amendment thereof) which, individually or in the aggregate, represent a
fundamental change in the information set forth in the registration statement.
Notwithstanding the foregoing, any increase or decrease in volume of securities
offered (if the total dollar value of securities offered would not exceed that
which was registered) and any deviation from the low or high end of the
estimated maximum offering range may be reflected in the form of prospectus
filed with the Commission pursuant to Rule 424(b) ((S)230.424(b) of this
chapter) if, in the aggregate, the changes in volume and price represent no
more than 20% change in the maximum offering price set forth in the
"Calculation of Registration Fee" table in the effective registration
statement.

  (iii) To include any material information with respect to the plan of
distribution not previously disclosed in the registration statement or any
material change to such information in the registration statement.

  (2) That, for the purpose of determining any liability under the Securities
Act of 1933, each such posteffective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

  (3) To remove from registration by means of a posteffective amendment any of
the securities being registered which remain unsold at the termination of the
offering.

  (b) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered

                                      II-1
<PAGE>

therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

  (c) The undersigned registrant hereby undertakes as follows: that prior to
any public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed underwriters, in addition to the information called
for by the other items of the applicable form.

  (d) The registrant undertakes that every prospectus: (i) that is filed
pursuant to paragraph (c) immediately preceding, or (ii) that purports to meet
the requirements of Section 10(a)(3) of the Act and is used in connection with
an offering of securities subject to Rule 415, will be filed as a part of an
amendment to the registration statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Securities Act of 1933, each such post-effective amendment shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

  (e) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers, and controlling persons of
the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer, or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer, or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.

  (f) The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Item 4, 10(b), 11, or 13 of this form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through
the date of responding to the request.

  (g) The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

                                      II-2

Ladies and Gentlemen:

In connection with the proposed registration under the Securities Act of 1933,
as amended, of a maximum of 16,000,000 shares of common stock, par value $1-2/3
per share, of Wells Fargo & Company, a Delaware corporation (the "Company"),
and associated preferred stock purchase rights (such shares and rights
collectively referred to as the "Shares"), which are proposed to be issued by
the Company in connection with the merger (the "Merger") of a wholly-owned
subsidiary of the Company with First Commerce Bancshares, Inc., I have examined
such corporate records and other documents, including the registration
statement on Form S-4 relating to the Shares, and have reviewed such matters of
law as I have deemed necessary for this opinion, and I advise you that in my
opinion:

  1. The Company is a corporation duly organized and existing under the laws
     of the state of Delaware.

  2. All necessary corporate action on the part of the Company has been taken
     to authorize the issuance of the Shares in connection with the Merger,
     and when issued as described in the registration statement, the Shares
     will be legally and validly issued, fully paid and nonassessable.

I consent to the filing of this opinion as an exhibit to the registration
statement.

Sincerely,

/s/ Stanley S. Stroup

Ladies and Gentlemen:

   We have acted as special counsel to First Commerce Bancshares, Inc., a
Nebraska corporation ("First Commerce"), in connection with the proposed merger
(the "Merger") of a direct, wholly-owned subsidiary of Wells Fargo & Company, a
Delaware corporation ("Wells Fargo"), with and into First Commerce, upon the
terms and conditions set forth in the Amended and Restated Agreement and Plan
of Reorganization, dated as of February 1, 2000, as amended and restated as of
April 14, 2000, by and among First Commerce, Wells Fargo, First National Bank
and Trust Co. of Kearney, The Overland National Bank of Grand Island, Western
Nebraska National Bank, and the First National Bank of West Point (the
"Agreement"). At your request, in connection with the filing of the
Registration Statement on Form S-4 filed with the Securities and Exchange
Commission in connection with the Merger (the "Registration Statement"), we are
rendering our opinion concerning certain federal income tax consequences of the
Merger. Any capitalized term used and not defined herein has the meaning given
to it in the Agreement.

   For purposes of the opinion set forth below, we have relied, with the
consent of First Commerce and the consent of Wells Fargo, upon the accuracy and
completeness of the statements and representations (which statements and
representations we have neither investigated nor verified) contained,
respectively, in the certificates of the officers of First Commerce and Wells
Fargo dated the date hereof, and have assumed that such statements and
representations will be complete and accurate at the Effective Time of the
Merger and that all statements and representations made to the knowledge of any
person or entity or with similar qualification are and will be true and correct
as if made without such qualification. We have also relied upon the accuracy of
the Registration Statement and the proxy statement-prospectus included therein
(the "Proxy Statement").

   We have also assumed that (i) the transactions contemplated by the Agreement
will be consummated in accordance therewith and as described in the
Registration Statement and the Proxy Statement (and no terms or conditions
therein material to this opinion will be waived), (ii) the Merger will be
reported by First Commerce and Wells Fargo on their respective federal income
tax returns in a manner consistent with the opinion set forth below, and (iii)
the Merger will qualify as a statutory merger under the applicable laws of the
State of Nebraska.

   Based upon and subject to the foregoing, under currently applicable United
States federal income tax law, it is our opinion that, for United States
federal income tax purposes, (i) the Merger will constitute a reorganization
within the meaning of Section 368 of the Internal Revenue Code of 1986, as
amended, (ii) no gain or loss will be recognized by the holders of First
Commerce common stock upon receipt of Wells Fargo common stock, except with
respect to cash received in lieu of fractional shares of Wells Fargo common
stock, (iii) the basis of Wells Fargo common stock received, including
fractional shares deemed received and redeemed, by the shareholders of First
Commerce will be the same as the basis of the First Commerce common stock
exchanged therefor and (iv) the holding period of shares of Wells Fargo common
stock received, including fractional shares deemed received and redeemed, by
the shareholders of First Commerce will include the holding period of the First
Commerce common stock, provided that the shares of First Commerce common stock
were held as a capital asset as of the Effective Time of the Merger.

   We express no opinion as to the United States federal income tax
consequences of the Merger to stockholders subject to special treatment under
United States federal income tax law (including, for example, foreign persons,
financial institutions, dealers in securities, traders in securities who elect
to apply a mark-to-market method of accounting, insurance companies, tax-exempt
entities, holders who dissent from the Merger and receive the fair value of
their shares of First Commerce common stock in cash, holders who acquired their
shares of First Commerce common stock through the exercise of an employee stock
option or right or otherwise as compensation, and holders who hold First
Commerce common stock as part of a hedge, straddle, conversion or constructive
sale transaction). In addition, no opinion is expressed with respect to the tax
consequences of the Merger under applicable foreign, state or local laws or
under any federal tax laws other than those pertaining to the income tax.

   We hereby consent to the filing of this opinion with the Securities and
Exchange Commission as an exhibit to the Registration Statement, and to the
references to us under the caption "The Merger--U.S. Federal Income Tax
Consequences of the Merger" and elsewhere in the Proxy Statement. In giving
such consent, we do not thereby admit that we are in the category of persons
whose consent is required under Section 7 of the Securities Act of 1933, as
amended.

   We are furnishing this opinion to you solely in connection with the filing
of the Registration Statement and this opinion is not to be relied upon,
circulated, quoted or otherwise referred to for any other purpose.

                                          Very truly yours,
