19.415—What must I do if a Federal agency excludes the participant or a principal after I enter into a covered transaction?
        
        (a) 
         You as an agency official may continue
 covered transactions with an excluded person, or
 under which an excluded person is a principal, if
 the transactions were in existence when the person
 was excluded. You are not required to continue the
 transactions, however, and you may consider
 termination. You should make a decision about
 whether to terminate and the type of termination
 action, if any, only after a thorough review to
 ensure that the action is proper.
    
    
        
        (b) 
         You may not renew or extend covered
 transactions (other than no-cost time extensions)
 with any excluded person, or under which an
 excluded person is a principal, unless you obtain
 an exception under  § 19.120.
