The two (2) year time period begins on the effective date, and the effective date serves as the anniversary date referred to in this Article.
   
2. AMENDMENTS. Amendments and/or supplements to this Agreement, negotiated subsequent to the signing of this Agreement, shall be accorded the same status as this Agreement and shall expire concurrently with this Agreement. Subsequent Agreements shall become effective on the date indicated in the Agreement or, if not specified, on the date signed by the Employer.
   
3. REOPENING. This Agreement is subject to reopening in accordance with the rights provided by Federal Service Labor Management Relations Statute, when amendments are required because of enactment or amendment of laws, government-wide rules or regulations, or Executive Orders; and at other times as may be required or upon mutual Agreement of the Parties.

   In the event that any provision of this Agreement shall be found or declared to be invalid by a court, or other authority, or by government regulation or decree, such decision(s) shall not invalidate the entire Agreement since it is the expressed intention of the Parties that all other provisions remain in full force and effect for the duration of the Agreement.

If such notice is given, the Agreement shall remain in full force and effect until the changes have been negotiated and approved. If neither Party serves timely notice the Agreement shall be renewed for the additional one (1) year period(s).
