          Interference No. 103,088                                                    














                                     APPENDIX A                                       
               The two counts in Int. No. 102,988 are as follows:                     
               Count 1                                                                
                    A composition comprising a papermaking filler                     
               material selected from the group consisting of                         
               finely ground natural calcium carbonate from                           
               limestone, precipitated calcium carbonate, clay,                       
               titanium dioxide, talc, silica/silicate pigments and                   
               combinations thereof, which has been surface-treated                   
               with from about Ø.1 to about 1Ø.Ø percent by weight,                   
               based on a dry weight of the filler material, of a                     
               cationic polymer, which is a dimer of the general                      
               formula                                                                
                                   R-CH=C-CH-R                                        
          * *                                                                         
                                        O-C=Ø                                         
               where R is a hydrocarbon group selected from the                       
               group consisting of alkyl with at least 8 carbon                       
               atoms, cycloalkyl with at least 6 carbon atoms,                        
               aryl, aralkyl and alkaryl, the dimer having been                       
               made cationic by treatment with at least one of a                      
               polyamino-amide and a polyamine polymer reacted with                   
                                         34
