            AGREEMENT (this "Agreement") dated January 23, 1996 among FIRST
BANK SYSTEM, INC., a Delaware corporation ("FBS"), ELEVEN ACQUISITION
CORP., a Delaware corporation and an indirect wholly-owned subsidiary of
FBS ("Acquisition"), FIRST INTERSTATE BANCORP, a Delaware corporation
("FI"), and WELLS FARGO & COMPANY, a Delaware corporation ("Wells").

            WHEREAS, FBS, Acquisition and FI entered into an Agreement and
Plan of Merger dated as of November 5, 1995 (the "Merger Agreement")
providing, upon the terms and subject to the conditions contained in the
Merger Agreement, for Acquisition to be merged with and into FI (the
"Merger");

            WHEREAS, in connection with the Merger Agreement, FI and FBS
entered into a Stock Option Agreement dated as of November 5, 1995 (the "FI
Option Agreement") pursuant to which FI granted to FBS an irrevocable
option (the "FI Stock Option") to purchase shares of FI Common Stock;

            WHEREAS, in connection with the Merger Agreement, FI and FBS
entered into a Letter Agreement dated November 5, 1995 (the "FI Fee
Agreement") pursuant to which FI agreed to pay FBS certain amounts under
certain circumstances;

            WHEREAS, concurrently with the execution and delivery of this
Agreement FI is terminating the Merger Agreement pursuant to Section 8.1(f)
thereof and entering into an agreement and plan of merger with Wells (the
"Wells Merger Agreement"); and

            WHEREAS, certain litigation is pending between the parties
hereto;

            NOW THEREFORE, in consideration of the foregoing and the mutual
agreements herein set forth, the parties do hereby agree as follows:

            1.    Payments by FI to FBS.  (a) FI irrevocably and
unconditionally agrees to pay FBS as early as practicable on January 24,
1996, by wire transfer in immediately available funds, $125,000,000;


 2


            (b)  Upon the occurrence of an Acquisition Event (as defined in
the FI Fee Agreement), FI irrevocably and unconditionally agrees to pay
FBS, on the date of such occurrence, by wire transfer in immediately avail-
able funds, $75,000,000; and

            (c)  The payment pursuant to Section 1(a) of this Agreement
shall be in full satisfaction of FI's obligations under the FI Option
Agreement and, to the extent provided in the Releases (as hereinafter
defined), in satisfaction of any claims that FBS may have against FI and
any other releasee for breach of the Merger Agreement and any claims that
FBS may have against Wells for tortious interference with the contractual
or prospective economic advantage resulting from the Merger Agreement, and
the payments pursuant to Sections 1(a) and 1(b) of this Agreement shall be
in full satisfaction of FI's obligations under the FI Fee Agreement.

            2.    Termination of Merger Agreement and Parent Agreements. 
FBS, FI and Acquisition agree that the Merger Agreement is hereby
terminated by FI in accordance with Section 8.1(f) thereof.  FBS and FI
further agree that the Parent Fee Letter and the Parent Option Agreement
(as such terms are defined in the Merger Agreement) are terminated and
rendered null and void effective immediately. 

            3.    Termination of FI Option Agreement and FI Fee Agreement.
FBS and FI agree that (i) FBS shall have no further rights under the FI
Option Agreement and such agreement shall be terminated and rendered null
and void effective immediately upon full and timely payment to FBS of the
amount referred to in Section 1(a) and (ii) FBS shall have no further
rights under the FI Fee Agreement immediately upon full and timely payment
to FBS of the amounts referred to in Sections 1(a) and 1(b) hereof.  FBS
and FI further agree that the FI Fee Agreement shall remain in full force
and effect until the timely payment to FBS of the amount referred to in
Section 1(b) hereof, provided, however, that FBS agrees not to seek any
amounts under the FI Fee Agreement unless and until the Wells Merger
Agreement is terminated without consummation of an Acquisition Event
involving Wells.  FBS and FI further agree that if the Wells Merger
Agreement is terminated after payment of the amount referred to in Section
1(a) and prior to the payment to FBS of the 

 3

amount referred to in Section 1(b) hereof, $25 million of the amount paid
to FBS pursuant to Section 1(a) hereof shall constitute payment pursuant to
Section 2(a) of the FI Fee Agreement.

            4.    Release; Withdrawal of Litigation, Regulatory Filings and
Protests.  Each of FBS, Acquisition, Wells and FI shall execute releases
immediately upon execution of this Agreement, substantially in the form
attached hereto as Exhibits A, B, C and D, as applicable (collectively the
"Releases").  Each party hereto shall take all steps necessary promptly to
withdraw or otherwise finally terminate with prejudice, without costs
imposed on any party, all litigation initiated by such party and to which
the Releases relate, including without limitation the cases set forth on
Schedule 4.  In addition, each party hereto will promptly withdraw any pro-
test or opposition which it has filed with the Board of Governors of the
Federal Reserve System or any other bank regulatory agency concerning any
application filed by any other party hereto with any such agency.  FBS
further agrees that it shall promptly following the execution of this
Agreement (i) withdraw its application filed with the Federal Reserve Bank
of Minneapolis on November 10, 1995 for approval from the Federal Reserve
Board of the Merger and the transactions contemplated thereby and all
applications and/or notices filed with state regulatory authorities in
connection with the Merger and (ii) withdraw or amend to be inapplicable to
any merger between FBS and FI or any acquisition by FBS of FI its Registra-
tion Statement on Form S-4 (File No. 33-64447) filed on November 21, 1995
with the Securities and Exchange Commission, as amended by Amendment No. 1
thereto dated December 29, 1995.

            5.    Effect of Termination; Confidentiality.  (a)  FBS,
Acquisition and FI agree that notwithstanding clause (ii) of Section 8.2 of
the Merger Agreement, none of FBS, Acquisition or FI shall have any
liabilities for any breach or alleged breach of the Merger Agreement,
including any willful breach.  As provided in clause (i) of said Section
8.2, Sections 6.2(b), 8.2 and 9.3 of the Merger Agreement and the
Confidentiality Agreement (as defined in said Section 6.2(b)) shall survive
the termination of the Merger Agreement.  Wells hereby agrees to be bound
by the confidentiality undertakings and agreements of the Confidentiality
Agreement, insofar as the 

 4

Confidentiality Agreement relates to information supplied by FBS or its
representatives to FI that becomes available to Wells, to the same extent
as FI is so obligated pursuant thereto.

                  (b)  Each of FBS and FI shall, as promptly as practicable
after the execution of this Agreement, (i) return to the other party or
destroy all Evaluation Material (as such term is defined in the
Confidentiality Agreement with respect to such party) in accordance with
the terms of the Confidentiality Agreement, and (ii) jointly instruct
Andersen Consulting ("Andersen") (A) not to issue its report with respect
to technology integration as provided for in its letter agreement with FBS
and FI (the "Andersen Agreement") and (B) to return to FBS or FI (as
applicable) as promptly as practicable the information provided by such
party to Andersen in connection with the preparation of such report and to
destroy all materials derived from or containing such information.  Each of
FBS and FI shall bear one-half of the fees and expenses of Andersen payable
under the Andersen Agreement.

            6.    Indemnification.  Wells hereby agrees to indemnify and
hold harmless FBS and Acquisition and their respective officers, directors,
employees, agents and advisors (the "FBS Parties") against any and all
liabilities, judgments, settlements, costs, reasonable expenses (including
legal fees) (collectively, "Losses") arising out of or in connection with
any claims (including, but not limited to, claims that have been or could
have been asserted in actions pending prior to the date hereof) by or on
behalf of any FI securityholders (or by any such securityholders on behalf
or purportedly on behalf of FI), arising out of or in connection with the
Merger Agreement, the FI Option Agreement, the FI Fee Agreement, this
Agreement or the transactions contemplated thereby and hereby but, to the
extent such Losses arise out of acts or omissions of FBS, only to the
extent that such acts or omissions shall have been taken prior to the date
hereof or are contemplated by this Agreement.  FBS hereby agrees that it
will, and will cause its affiliates to, cooperate with Wells in connection
with any litigation or claims for which indemnification is sought pursuant
to the preceding sentence.  FBS and Acquisition further agree that they
will not settle any such litigation without the prior written consent of
Wells, which consent

 5

will not be unreasonably withheld.  Wells also agrees to indemnify the FBS
Parties against all reasonable legal fees or other expenses incurred in
enforcing this Agreement.  In addition, FI agrees promptly to reimburse FBS
for legal expenses (not to exceed $225,000) incurred in connection with any
such securityholder litigation prior to the date hereof.

            7.    Waiver of Jury Trial.  TO THE FULLEST EXTENT PERMITTED BY
APPLICABLE LAW, EACH OF THE PARTIES HERETO HEREBY WAIVES, AND COVENANTS
THAT IT WILL NOT ASSERT (WHETHER AS PLAINTIFF, DEFENDANT OR OTHERWISE), ANY
RIGHT TO TRIAL BY JURY IN ANY FORUM IN RESPECT OF ANY ISSUE, CLAIM, DEMAND,
ACTION OR CAUSE OF ACTION ARISING OUT OF OR BASED UPON THIS AGREEMENT, OR
THE SUBJECT MATTER HEREOF IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER
ARISING OR WHETHER IN CONTRACT, TORT, EQUITY OR OTHERWISE.

            8.    Validity; Due Authorization.  Each party hereto
represents and warrants to the others that it is duly authorized to execute
and deliver this Agreement and the relevant Release, that no further
corporate authorizations (including shareholder approvals or approval under
Section 203 of the Delaware General Corporation Law) are required for such
party's execution, delivery and performance of this Agreement and the
relevant Release, and that this Agreement and such Release is a valid and
binding obligation of such party.

            9.    Specific Performance.  The parties hereto acknowledge
that damages would be an inadequate remedy for any breach of the provisions
of this Agreement and agree that the obligations of the parties hereunder
shall be specifically enforceable and no party shall take any action to
impede the others from seeking to enforce such rights of specific
performance.

            10.   Notices.  All notices, requests, claims, demands and
