          Application No. 08/649,504                                                  


                                       APPENDIX                                       
               1.  An electronic assembly comprising:                                 
               A.  a first electronic component with a first contacting               
          site;                                                                       
               B.  a second electronic component with a second contacting             
               site;                                                                  
               C.  a force bearing member which maintains contact between             
                    the                                                               
               first contacting site on the first electronic component                
          and the second contacting site on the second electronic                     
               component, wherein the force bearing member is made of                 
          a                                                                           
          cured composition comprising:                                               
                    a)   an addition curable silicone polymer comprising              
                         an average of at least 2 unsaturated functional              
                         groups per molecule;                                         
                    b)   a crosslinker comprising an average of at least 2            
                         silicone-hydrogen linkages per molecule, wherein,            
                         prior to cure, the ratio of Si-H linkages to                 
                         functional groups on the silicone polymer (SiH:F             
                         ratio) is about 1:1 to about 20:1; and                       
                    c)   a catalyst, wherein said catalyst is present in              
                         an amount sufficient to permit curing of the                 
                         composition in less than about 20 minutes at a               
                         temperature of about 30°C.
