Shares (the "REGISTRATION STATEMENT") and shall effect all such 
registrations, qualifications and compliances (including, without limitation, 
obtaining appropriate qualifications under applicable state securities or 
"blue sky" laws and compliance with any other applicable governmental 
requirements or regulations) as any selling Holder may reasonably request and 
that would permit or facilitate the sale of all Registrable Shares (provided 
however that Acquiror shall not be required in connection therewith to 
qualify to do business or to file a general consent to service of process in 
any such state or jurisdiction), and in each case



par

Acquiror will use its best efforts to cause such Registration Statement and all
