This First Amendment may be executed in any number of counterparts, but all of such counterparts shall together constitute but one and the same agreement. In making proof of this First Amendment, it shall not be necessary to produce or account for more than one counterpart thereof signed by each of the parties hereto. Delivery of an executed counterpart of this First Amendment by telecopier or other electronic means shall have the same force and effect as delivery of an original executed counterpart of this First Amendment. Any party delivering an executed counterpart of this First Amendment by telecopier or other electronic means also shall deliver an original executed counterpart of this First Amendment, but the failure to deliver an original executed counterpart shall not affect the validity, enforceability, and binding effect of this First Amendment as to such party or any other party.
