          CLASS ACTION COMPLAINT   Plaintiff alleges upon
          information and belief except as to paragraph 1, which is
          alleged on knowledge, as follows:

          THE PARTIES

                    1.   Plaintiff is and has been at all relevant
          times, the owners of shares of the common stock of First
          Interstate Bancorp ("First Interstate" or the "Company").

                    2.   First Interstate is a bank holding company
          organized and existing under the laws of the State of
          Delaware.  First Interstate operates approximately 1,000
          offices in 13 states.  It has approximately 76 million
          shares of common stock issued and outstanding, held by
          approximately 25,000 shareholders of record.  Its shares
          are traded on various stock exchanges, including the New
          York Stock Exchange.

                     3.  (a)  Defendant Edward M. Carson ("Carson")
          is and was at all relevant times Chairman of the Board of
          Directors of First Interstate.

                         (b)  Defendant William S. Randall
          ("Randall") is and was at all relevant times a Director
          and Executive Vice President and Chief Operating Officer
          of First Interstate.

                         (c)  Defendant William E.B. Siart
          ("Siart") is and was at all relevant times a Director and
          President and Chief Executive Officer of First
          Interstate.

                         (d)  Defendants John E. Bryson ("Bryson"),
          Jewel Plummer Cobb ("Cobb"), Ralph P. Davidson
          ("Davidson"), Myron Du Bain ("Du Bain"), Don C. Frisbee
          ("Frisbee"), George M. Keller ("Keller"), Thomas L. Lee
          ("Lee"), William F. Miller ("Miller"), Steven B. Sample
          ("Sample"), Forrest N. Shumway ("Shumway"), Richard J.
          Stegemeier ("Stegemeier") and Daniel M. Tellep ("Tellep")
          (together with defendants Carson, Randall and Siart "the
          Individual Defendants") are and were at all relevant
          times directors of the Company.

                    4.   The Individual Defendants are in a
          fiduciary relationship with plaintiff and the other
          public stockholders of First Interstate and owe to
          plaintiff and other members of the class (as hereinafter
          defined) the highest obligations of good faith, fair
          dealing and full and candid disclosure.

                    5.   Defendant First Bank System, Inc. ("First
          Bank") is a Delaware bank holding corporation
          headquartered in Minneapolis, Minnesota.  First Bank is
          named herein as an aider and abettor to the breaches of
          fiduciary duty alleged herein.

                    6.   Defendant Eleven Acquisition Corporation
          is a Delaware corporation formed by First Bank for the
          purpose of effecting the First Bank Merger (defined
          below).

          CLASS ACTION ALLEGATIONS

                    7.   Plaintiff brings this case on his own
          behalf and as a class action, pursuant to Rule 23 of the
          Rules of the Court of Chancery, on behalf of all public
          stockholders of First Interstate, and their successors in
          interest, who are or will be threatened with injury
          arising from defendants' actions as more fully described
          herein.  Excluded from the class are defendants herein
          and any person, firm, trust, corporation, or other entity
          related to or affiliated with any of the defendants.

                    8.   This action is properly maintainable as a
          class action.

                    9.   The class is so numerous that joinder of
          all members is impracticable.  There are approximately
          25,000 stockholders of record located throughout the
          United States.

                    10.  There are questions of law and fact which
          are common to the class and which predominate over
          questions affecting any individual class member,
          including whether the Individual Defendants have breached
          their fiduciary duties owed to plaintiff and other
          members of the class.

                    11.  Plaintiff is committed to prosecuting this
          action and has retained competent counsel experienced in
          litigation of this nature.  The claims of plaintiff is
          typical of the claims of other members of the class and
          plaintiff has the same interests as the other members of
          the class.  Accordingly, plaintiff is an adequate
          representative of the class and will fairly and
          adequately protect the interests of the class.

                    12.  The prosecution of separate actions by
          individual members of the class would create the risk of
          inconsistent or varying adjudications with respect to
          individual members of the class which would establish
          incompatible standards of conduct for defendants, or
          adjudications with respect to individual members of the
          class which would as a practical matter be dispositive of
          the interests of the other members not parties to the
          adjudications or substantially impair or impede their
          ability to protect their interests.

                    13.  The defendants have acted, or refused to
          act, on grounds generally applicable to, and causing
          injury to, the class and, therefore, preliminary and
          final injunctive relief on behalf of the class as a whole
          is appropriate.

          BACKGROUND AND CLAIM FOR RELIEF

          The Original Wells Fargo Proposal

                    14.  Wells Fargo & Company ("Wells Fargo") is a
          Delaware corporation with executive offices at 420
          Montgomery Street, San Francisco, California.  Wells
          Fargo is a bank holding company with subsidiaries that
          perform commercial banking operations, investment
          advisory services, international and mortgage banking
          services, credit card services and other related
          financial activities.

                    15.  Wells Fargo has long been interested in
          acquiring First Interstate.  In February 1994, Wells
          Fargo offered to purchase the Company, which offer was
          rebuffed by First Interstate.  However, Paul Hazen,
          Chairman of Wells Fargo, met with defendant Siart in or
          around the first two weeks of October, 1995 to discuss a
          possible transaction, and was once again rebuffed.

                    16.  On or about October 18, 1995, Wells Fargo
          announced in a press release that it had submitted an
          unsolicited merger proposal to First Interstate to
          acquire 100 percent of the Company's common stock (the
          "original WF proposal").  Pursuant to the terms of the
          original WF proposal, First Interstate shareholders would
          receive .625 of a share of Wells Fargo, representing a
          value of $133.50 for each First Interstate share based on
          the then-current trading price of Wells Fargo stock.  The
          transaction, valued at approximately $10 billion,
          contemplated a merger of First Interstate and Wells Fargo
          into a new company.

                    17.  The reaction of the investment community
          to the original WF proposal was positive.  Analysts noted
          that the proposal was nearly three times First
          Interstate's book value, and that most recent bank
          mergers were priced closer to 2 to 2-1/2 times book
          value.  Analysts referred to the proposal as "a knockout
          bid" (Bert Ely, an Alexandria, Virginia banking
          consultant); an "excellent" potential combination (Jeff
          Simons of Mackay Shields Financial Corp., which owns 1.4
          million Company shares); and a "super deal" (Paul McKey
          of Dean Witter Reynolds).  It was further reported that
          Kohlberg Kravis Roberts & Co., which owns approximately
          9% of the Company's stock, supported the original WF proposal.

                    18.  In response to Wells Fargo's announcement
          on October 18, 1995, the Company's stock price soared
          from $106 per share to over $140 per share. 

          Additionally, the price of Wells Fargo stock increased
          immediately after the announcement of the original WF
          proposal approximately 7%, to $229 per share.
          First Interstate's Response and The First Bank Merger

                    19.  In contrast to the positive reaction of
          the investment community, the Company promptly reacted
          negatively to the original WF proposal.  On October 18,
          1995, defendant Siart stated "I am deeply disappointed
          that Wells Fargo would take this uninvited action." 
          Siart reportedly also stated that it was in First
          Interstate's best interest to take six months to consider
          the Company's other options.

                    20.  Moreover, in response to Wells Fargo's
          offer to increase its proposal to .65 shares of Wells
          Fargo stock per First Interstate share, the First
          Interstate Board initiated an active bidding process
          seeking to sell First Interstate.  First Interstate met
          and shared confidential information with at least three
          banks, including First Bank, Norwest Corporation and Banc
          One Corporation.  However, in breach of fiduciary duties
          to First Interstate's public shareholders, the First
          Interstate Board wrongfully failed duly to explore,
          consider and evaluate the available alternatives, and to
          proceed in good faith to negotiate with respect to the
          alternatives to obtain the best transaction reasonably
          available for First Interstate shareholders.

                    21.  Nevertheless, less than three weeks later,
          on or about November 6, 1995, First Interstate announced
          that it had agreed to be acquired by First Bank ("First
          Bank Merger") in a transaction which would give the First
          Interstate stockholders lower consideration than in the
          original WF proposal.  Pursuant to the terms of the First
          Bank Merger, First Bank will exchange 2.6 shares of its
          common stock for each First Interstate share of common
          stock, valuing the Company's stock at $129.68 per share,
          for a total value of $10.05 billion.

                    22.  Prior to November 6, 1995, Wells Fargo had
          offered to increase its offer to .65 shares of Wells
          Fargo common stock per First Interstate share.  Based on
          the closing price of Wells Fargo common stock on November
          3, 1995, the last trading date prior to announcement of
          the First Bank Merger, the .65 shares of Wells Fargo
          stock had an implied value of $137.96 per First
          Interstate share.

                    23.  In connection with the First Bank Merger,
          First Interstate and First Bank agreed to a $100 million
          termination fee in the event a third party offer were
          accepted by First Interstate.  Moreover, as a condition
          to the First Bank Merger, First Interstate and First Bank
          entered into reciprocal stock option agreements as of
          November 5, 1995 pursuant to which First Interstate
          granted First Bank an option to purchase up to 15,073,106
          shares of the Company's common stock at a price of
          $127.75 per share and First Bank granted First Interstate
          an option to purchase up to 25,829,983 shares of First
          Bank common stock at a price of $50.875 per share. First
          Bank could reap profits of as much as $100,000,000 from
          the option granted to it.  As a consequence of the
          termination fee and option agreement, Wells Fargo or any
          other interested bidder might have to pay First Bank as
          much as $200,000,000 if the First Bank Merger were
          terminated

                    24.  As a special enticement to the Individual
          Defendants to accept the First Bank Merger, First Bank
          agreed that the combined company would be called First
          Interstate and, although it would maintain principal
          offices in Minneapolis, its "core businesses" would be
          run from California, an obvious effort to placate First
          Interstate executives.  Thus, the First Bank Merger
          assures that defendant Siart (who will be second in
          command in the combined company) and other First
          Interstate executives will maintain their positions and
          the valuable perquisites which flow therefrom.  In
          addition, the Board of Directors of the combined entity
          will be evenly divided between First Bank and First
          Interstate directors.  Not surprisingly, as a result, one
          analyst labeled the First Bank Merger as "a senior
          management job preservation act" for First Interstate
          executives.

                    25.  In addition, the Individual Defendants, in
          agreeing to the First Bank Merger, failed to effectively
          conduct a fair bidding contest for the sale of the
          Company.  Indeed, they agreed to the First Bank Merger to
          thwart spirited bidding by Wells Fargo or anyone other
          than First Bank desirous of acquiring First Interstate in
          a value maximizing transaction.  The Individual
          Defendants failed to take all steps to ensure that First
          Interstate's shareholders had the benefit of the most
          advantageous transaction, including but not limited to,
          failing to negotiate for Wells Fargo's highest and best
          offer.  Moreover, it has been reported that other
          potential First Interstate bidders, including Norwest
          Corp. or Banc One Corp., might have offered a higher bid,
          but did not because of Siart's and the other Individual
          Defendant's requirements that First Interstate keep its
          name and California headquarters.

                    26.  In response to the announcement of the
          First Bank Merger, the prices of the common stock of both
          First Bank and First Interstate both declined.

                    27.  Executives at First Bank and First
          Interstate quickly sought to justify the attractiveness
          of the deal, asserting that the companies would be able
          to save $500 million in expense reductions through
          overlapping operations.  However, the only overlap
          between the companies is in Montana, Colorado and
          Wyoming.  If the First Bank Merger were consummated,
          elimination of this redundancy would generate a mere one-
          time $80 million in savings.  In contrast, a merger
          between Wells Fargo and First Interstate would create
          dozens of duplicate branches, which, when eliminated,
          would contribute substantially to the $800 million cost
          cuts forecast by Wells Fargo.

                    28.  As announced, the consideration offered by
          the First Bank Merger on its face is lower than that
          offered even in the original WF proposal.

                    26.  Evidencing the fact that the Individual
          Defendants acted precipitously and recklessly in agreeing
          to the First Bank Merger with knowledge that other and
          higher bids were available, on or about November 13,
          1995, Wells Fargo announced that it would commence a
          tender offer for First Interstate stock.  Pursuant to the
          terms of its tender offer Wells Fargo will give First
          Interstate stockholders two-thirds of a share of Wells
          Fargo common stock for each First Interstate share. 
          Based upon the closing price of Wells Fargo on November
          10, 1995, the value of the exchange offer is $143.58 per
          First Interstate share, or approximately $10.9 billion in
          total.

                    29.  In addition, Wells Fargo announced that it
          intends to file preliminary proxy materials with the SEC
          in connection with the solicitation of First Interstate
          shareholders to vote against approval of the First Bank
          Merger, and announced that it will file with the SEC
          preliminary materials to solicit written consents from
          First Interstate stockholders to remove the First
          Interstate board and replace it with Wells Fargo nominees
          who are committed to removing any impediments to the
          consummation of the acquisition of First Interstate by
          Wells Fargo.  Moreover, on November 13, 1995, Wells Fargo
          filed suit in this Court seeking declaratory and
          injunctive relief against First Interstate and its Board,
          and First Bank and Eleven Acquisition Corporation.

                    27.  First Interstate also has in place a
          shareholder rights plan (commonly known as a "poison
          pill") which makes an unwelcome takeover of the Company
          prohibitively expensive.  The poison pill is triggered by
          the acquisition of 20% or more of First Interstate's
          common stock by a group or persons unfavored by First
          Interstate's management.  The poison pills effects a
          fundamental shift of power from the shareholders of First
          Interstate to the Individual Defendants.  The poison pill
          permits the Individual defendants to act as the prime
          negotiators of -- and, in effect, totally to preclude --
          any and all acquisition offers which they disfavor
          through their power to redeem or to refuse to redeem the
          rights.

                    30.  Further, By-law 4(b) of First Interstate's
          By-laws require that notice of a nomination of a
          candidate for director "delivered to or mailed and
          received at the principal executive offices of the
          Corporation not less than thirty days nor more than sixty
          days prior to the meeting...".  The By-law further states
          that "[o]nly persons who are nominated in accordance with
          [such] procedures shall be eligible for election as
          directors of [First Interstate]."  The By-law wrongfully
          purports to restrict the power of First Interstate
          stockholders to act by written consent to elect or remove
          directors.

                    28.  This fundamental shift of control of the
          Company's destiny from the hands of its shareholders to
          the hands of the Individual Defendants results in a
          heightened fiduciary duty on the part to consider, in
          good faith, a third-party bid, and further requires the
          Individual Defendants to pursue a third-party's interest
          in acquiring the Company and to negotiate in good faith
          on behalf of the Company's shareholders with a bidder
          such as Wells Fargo.  In violation of their heightened
          fiduciary duties, the Individual Defendants have used the
          poison pill to favor one bidder -- First Bank -- over
          another -- Wells Fargo.  The First Bank Merger is exempt
          from the poison pill, whereas the poison pill still bars
          Wells Fargo from proceeding with its superior offer
          without the consent of the Individual Defendants.

          CLAIM FOR RELIEF

                    29.  The Individual Defendants are obligated to
          carefully consider, in a timely fashion and on an
          informed basis, bona fide proposals from third parties to
          engage in transactions which will maximize value for
          First Interstate shareholders; not to place their own
          self-interests and personal considerations ahead of the
          interests of the public stockholders; and to make
          corporate decisions in good faith.

                    30.  The Individual Defendants' fiduciary
          obligations require them to:

                         (a)  undertake an appropriate evaluation
          of all bona fide offers, and take appropriate steps to
          consider all potential bids for the Company or its assets
          or explore strategic alternatives, in order to maximize
          shareholder value;

                         (b)  act independently, including
          appointing a disinterested committee so that the
          interests of First Interstate's public stockholders will
          be protected;

                         (c)  adequately ensure that no conflicts
          of interest exist between the Individual Defendants' own
          interests and their fiduciary obligations to the public
          stockholders of First Interstate;

                         (d)  utilize the poison pill in a manner

          designed to maximize shareholder value; and

                         (e)  avoid implementing any procedures
          which would impede the maximum bona fide offer for First
          Interstate.

                    31.  In effect, the Individual Defendants have
          initiated a process which has placed the Company up for
          sale, including initiating an active bidding contest
          seeking to sell the Company, obligating them to maximize
          shareholder value.  Nevertheless, the Individual
          Defendants necessarily and inherently suffer from a
          conflict of interest between their own personal desires
          to retain their offices in First Interstate, with the
          emoluments and prestige which accompany those offices,
          and their fiduciary obligation to maximize shareholder
          value in a transaction.  Because of such conflict of
          interest, the Individual Defendants have been and remain
          unable to represent the interests of First Interstate's
          public stockholders with the impartiality that their
          fiduciary duties require, nor have they been able to
          ensure that their conflicts of interest will be resolved
          in the best interests of First Interstate's public
          stockholders.

                    32.  By virtue of the acts and conduct alleged
          herein, the Individual Defendants have breached their
          fiduciary duties owed to plaintiff and other class
          members by carrying out a preconceived plan and scheme to
          entrench themselves in office and to protect and advance
          their own parochial interests at the expense of First
          Interstate's public shareholders.  The Individual
          Defendants have not exercised and are not exercising
          independent business judgment and have acted and are
          acting to the detriment of the class.  The Individual
          Defendants' negative response to Wells Fargo, the hasty
          acceptance of the First Bank Merger which provides less
          consideration than the WF initial and amended proposals,
          and their failure to adequately consider other offers,
          was an uninformed knee-jerk reaction designed to advance
          their own interests and was made without adequate
          information as to what a third party would be prepared to
          offer in a fully negotiated transaction.

                    33.  The Individual Defendants have refused to
          take the steps necessary to ensure that the Company's
          public shareholders will receive maximum value for their
          shares of First Interstate common stock.  The Individual
          Defendants' agreement to the inferior First Bank merger
          rather than meaningfully responding to Wells Fargo's
          proposals or pursuing a value maximizing transaction with
          other bona fide companies is clearly the result of a
          desire by the Individual Defendants to protect their own
          substantial salaries, perquisites and positions with the
          Company.

                    34.  As a result of the foregoing, the
          Individual Defendants have breached their fiduciary
          duties owed to First Interstate's stockholders.

                    35.  Defendants First Bank and Eleven
          Acquisition Corporation have knowingly and substantially
          participated in and are benefiting by breaches of
          fiduciary duties by the Individual Defendants and,
          therefore, are liable as aided and abettors thereof. 
          Indeed, the First Bank Merger could not proceed without
          the willing and active participation of First Bank and
          Eleven Acquisition Corporation.

                    36.  Unless enjoined by this Court, defendants
          will continue to breach their fiduciary duties owed to
          plaintiff and the other members of the Class and/or aid
          and abet such breaches in order to benefit themselves at
          the expense and to the irreparable harm of the Class.

                    37.  Plaintiff and the other members of the
          Class have no adequate remedy at law.

                    WHEREFORE, plaintiff demands judgment as
          follows:

                    1.   declaring this to be a proper class
          action;

                    2.   enjoining the First Bank Merger until all
          value maximizing alternatives are fully explored;

                    3.   in the event the First Bank Merger is
          consummated, rescinding it or awarding rescissory damages
          to the class;

                    4.   declaring null and void the termination
          fee and stock option agreements in the First Bank Merger
          agreement and bylaw 4(b) to the extent it obstructs
          shareholders action by written consent;

                    5.   ordering the Individual Defendants to
          carry out their fiduciary duties to plaintiff and the
          other members of the Class by:

                         (a)  cooperating fully with any person or
          entity having a bona fide interest in proposing a
          transaction which would maximize shareholder value;

                         (b)  undertaking an appropriate evaluation
          of First Interstate's worth as a merger/acquisition
          candidate;

                         (c)  taking all appropriate steps to
          enhance First Interstate's value and attractiveness as a
          merger/acquisition candidate;

                         (d)  taking all appropriate steps to
          effectively expose First Interstate to the marketplace in
          an effort to create an active auction for First
          Interstate;

                         (e)  acting independently so that the
          interests of First Interstate's public stockholders will
          be protected; and

                         (f)  adequately ensuring that no conflicts
          of interest exist between the Individual Defendants' own
          interests and their fiduciary obligation to maximize
          stockholder value or, if such conflicts exist, ensuring
          that all conflicts are resolved in the best interests of
          First Interstate's public stockholders; 

                    6.   ordering defendants, jointly and
          severally, to account to plaintiff and the other members
          of the Class for all damages suffered and to be suffered
          by them as a result of the wrongs complained of herein;

                    7.   directing the Individual Defendants to
          employ the poison pill in a manner consistent with
          maximizing shareholder value;

                    8.   awarding plaintiff the costs and
          disbursements of this action, including a reasonable
          allowance for plaintiff's attorneys' and experts' fees;
          and

                    9.   granting such other and further relief as
          this Court may deem to be just and proper.
