19.120—May we grant an exception to let an excluded person participate in a covered transaction?
        
        (a) 
         The Secretary of the Treasury may grant an
 exception permitting an  excluded
 person to participate in a particular covered
 transaction. If the Secretary of the Treasury
 grants an exception, the exception must be in
 writing and state the reason(s) for deviating from
 the governmentwide policy in Executive Order
 12549.
    
    
        
        (b) 
         An exception granted by one agency for an
 excluded person does not extend to the covered
 transactions of another agency.
