To amend the Defense Base Act to exclude Guam.

This bill amends the Defense Base Act to explicitly exclude Guam from its coverage. It modifies the law's definition of "Territory or possession outside the continental United States" by adding a new provision stating Guam is not included. As a result, Guam would no longer be considered a covered territory under this specific federal workers' compensation law for defense-related work. The change directly affects Guam's status regarding benefits for defense workers employed there under this act.
