          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;

     (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 available 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 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 protest 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 Registration 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


                                        2




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 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 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

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

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
