(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 Sec. 620.120.
