&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. This Second Amendment may be entered into in one or more counterparts, all of which shall be considered one and the same instrument, and it shall become effective when one or more counterparts have been signed by each of the parties and delivered to the other parties, it being understood that all parties need not sign the same counterpart.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5. Except as expressly modified herein, the terms of the Agreement, as amended by the First Amendment, remain unchanged and in full force and effect.
