| A: | 
             The conduct of a Science Based
                 Stockpile Stewardship program to ensure a high level of
                 confidence in the safety and reliability of nuclear weapons
                 in the active stockpile, including the conduct of a broad
                 range of effective and continuing experimental programs.     | 
            | B: |  The maintenance of modern nuclear
                 laboratory facilities and programs in theoretical and
                 exploratory nuclear technology which will attract, retain,
                 and ensure the continued application of our human scientific
                 resources to those programs on which continued progress in
                 nuclear technology depends.     | 
            | C: |  The maintenance of the basic
                 capability to resume nuclear test activities prohibited by
                 the CTBT should the United States cease to be bound to
                 adhere to this treaty.     | 
            | D:  |  Continuation of a comprehensive
                 research and development program to improve our treaty
                 monitoring capabilities and operations.     | 
            | E: |     The continuing development of a
                 broad range of intelligence gathering and analytical
                 capabilities and operations to ensure accurate and
                 comprehensive information on worldwide nuclear arsenals,
                 nuclear weapons development programs, and related nuclear
                 programs.     | 
            | F: |    The understanding that if the
                 President of the United States is informed by the Secretary
                 of Defense and the Secretary of Energy (DOE) -- advised by
                 the Nuclear Weapons Council, the Directors of DOE's nuclear
                 weapons laboratories and the Commander of the U.S. Strategic
                 Command -- that a high level of confidence in the safety or
                 reliability of a nuclear weapon type which the two
                 Secretaries consider to be critical to our nuclear deterrent
                 could no longer be certified, the President, in consultation
                 with Congress, would be prepared to withdraw from the CTBT
                 under the standard "supreme national interests" clause in
                 order to conduct whatever testing might be required. |
