          conducted iterative testing on its accounts following the vendor's          
          rewriting of the software.                                                  
               The second notable change was to increase the speed by which           
          the purchases and sales of securities by portfolio managers could           
          be sent from the Micro IS system to the Trust TU system.  This              
          change required the writing of polling software that essentially            
          checked the Micro IS system every 8 to 10 seconds in order to               
          determine the occurrence of any trades that needed to be sent to            
          the Trust TU system.  The increased speed was achieved by writing           
          the program in a language called Clipper, after the rejection of            
          two other languages.                                                        
               Each of these changes resulted in increased efficiency in the          
          use of the Micro IS system both in terms of cost per account and            
          speed of nightly batch processing.                                          
               C.  Success                                                            
               The Success system was designed in-house by Norwest to improve         
          the speed and efficiency of the data processing for Norwest's               
          equipment leasing business.  It supported all aspects of leasing            
          activity, including origination of contracts, tracking assets,              
          invoicing customers, tracking collection, accounting, cash                  
          management, and off-line reporting.  Success was developed between          
          1988 and 1991 by a group of 15 to 20 people within the Norwest              
          Financial Information Services Group (NFISG), the data processing
