                   FIRST BANK SYSTEM TO ACQUIRE U.S. BANCORP

 MERGER CREATES $70 BILLION BANKING ORGANIZATION IN 17 CONTIGUOUS STATES UNDER
           THE NAME U.S. BANCORP; HEADQUARTERS TO BE IN MINNEAPOLIS

     MINNEAPOLIS/PORTLAND, March 20, 1997 -- First Bank System, Inc. 
(NYSE:FBS) and U.S. Bancorp (NASDAQ:USBC) today announced the signing of a 
definitive agreement for FBS to acquire Portland, Oregon-based U.S. Bancorp. 
The resulting company, which will be called U.S. Bancorp, will create the 8th 
largest banking organization in the U.S. based on market capitalization, and 
the 14th largest banking organization based on assets. The combined 
organization will serve nearly 4 million households and 475,000 businesses in 
17 contiguous states.

     Under terms of the agreement, U.S. Bancorp shareholders will receive a 
tax-free exchange of 0.755 shares of FBS common stock for each share of U.S. 
Bancorp common stock. Based on FBS's closing stock price on March 19, 1997, 
this exchange ratio represents a price of $59.08 for each U.S. Bancorp share, 
resulting in a purchase price of approximately $9 billion.



                                       -2-

     "Together, our combined company will become the best-performing major 
bank in the United States, a regionally-based, nationally-competitive bank 
that uses technology to drive superior efficiency and customer service," said 
John F. Grundhofer, chairman, president and chief executive officer of First 
Bank System. "Our regions are contiguous, compatible and are in attractive 
growth markets. Our banks both have strong market presence. Our business 
strategies are virtually identical. Our business lines and products 
complement each other. And each of us has special skills and resources to 
offer the other. You could live a couple of lifetimes without finding another 
fit this good."

     Grundhofer will serve as the president and chief executive officer of 
the combined organization. U.S. Bancorp chairman and CEO, Gerry B. Cameron, 
will serve as chairman until his retirement in 1998. Joining Grundhofer's 
current direct reports will be Gary T. Duim and Robert D. Sznewajs, who will 
be vice chairmen in the new U.S. Bancorp.

     Cameron said, "U.S. Bancorp and First Bank System both have strong 
reputations for superior customer service, excellent employees, community 
involvement and future-focused thinking. These two organizations will 
integrate very well. Employees will be key to the future success of the 
combined company as we provide customers with enhanced products and services 
over a wider geographic territory."



                                       -3-

     The transaction is expected to be accretive to FBS earnings per share in 
the second quarter of 1998, nine months after closing. By 1999, FBS estimates 
earnings per share accretion of approximately 8 percent. FBS said it would 
incur pre-tax merger-related charges totaling $625 million through the second 
quarter of 1998. The acquisition will be accounted for as a pooling. The FBS 
board of directors has rescinded its stock repurchase authorization. In 
connection with the merger agreement, FBS and U.S. Bancorp have each granted 
the other an option for 19.9% of its outstanding shares exercisable under 
certain circumstances with a potential value of between $200 million and $300 
million.

     FBS estimated that an expense reduction of approximately $340 million 
(pre-tax), or stated as a percentage, representing 28 percent of U.S. 
Bancorp's operating expenses, would be created by centralizing data 
processing, staff functions and some operations functions as well as through 
standardizing products, improving technology, and branch efficiencies and 
offering customers increased alternative delivery channels for bank products 
and services. The companies estimated that their combined operating expenses 
would be reduced by 14 percent.

     The companies said that as with any merger of this magnitude, job loss 
at both organizations will be unavoidable. Approximately 4,000 positions will 
be eliminated, however, both companies said they were committed to do 
whatever they could to minimize the impact through hiring restrictions, 
normal attrition and redeploying employees into other positions.



                                       -4-

     FBS said the transaction would enable it to leverage its unique position 
in the payment systems business by offering those services to U.S. Bancorp's 
extensive corporate customer base. FBS is the largest provider of Visa 
corporate and purchasing cards in the world. Other anticipated revenue 
enhancements include capitalizing on FBS' success in home equity lending, 
exporting U.S. Bancorp's market position and expertise in leasing to FBS' 
franchise, and bringing First Bank's investment management expertise to U.S. 
Bancorp's customers.

     The combined organization will use the name U.S. Bancorp and will be 
headquartered in Minneapolis. "The U.S. Bancorp name better reflects the 
expanded geographic service area of the combined organizations," Grundhofer 
explained. FBS said it intends to establish Portland as a major development 
site for its ongoing technology efforts which will be critical in order to 
address the needs of the combined organization. "Employees will be part of a 
stronger, even more dynamic industry leader," Grundhofer noted. "The merger 
enhances management depth, capitalizes on shared experience and creates 
future opportunities for employees of the new U.S. Bancorp.

     "The new U.S. Bancorp will have a strong shared vision in serving 
customers," Grundhofer added. "The investments that FBS has already made in 
technology to enhance customer satisfaction and address their needs can be 
used to the benefit of U.S. Bancorp's customers. And the combined 
organization will have the critical mass to invest even further in innovative 
products and services." Cameron also emphasized 



                                       -5-

that the complementary nature of the two companies' businesses and priorities 
as well as the non-overlapping nature of the markets served by each company 
would minimize disruption for customers. "We are very focused on customer 
needs," stated Cameron. "Mergers can be disruptive and we are determined to 
make this transition as smooth as possible." Customers will have access to 
nearly 1,000 branch offices, more than 4,500 ATMs and continued 24-hour 
customer service. Business customers will continue to have their needs 
supported through local decision making as well as over 80 products and 
services.

     "Both companies have strong records as community partners and we are 
totally committed to continuation of that record. Our mutual focus has been 
one of community development and reinvestment initiatives that build 
economically strong neighborhoods and contribute to the quality of life. The 
effort has earned both our companies outstanding Community Reinvestment Act 
(CRA) ratings in our major markets, as well as a high degree of community 
goodwill," Grundhofer noted.

     The FBS and U.S. Bancorp boards of directors will be combined. FBS 
currently has 16 directors; U.S. Bancorp currently has 12 directors. The 
boards of both organizations have unanimously approved the acquisition. The 
acquisition is contingent upon regulatory and shareholder approvals and is 
expected to close in the third quarter of 1997.
