The submission of a signature page transmitted by facsimile (or similar electronic transmission facility, including PDF via email) shall be considered as an “original” signature page for purposes of this Agreement so long as the original signature page is thereafter transmitted by mail or by other delivery service and the original signature page is substituted for the facsimile (or similar electronic transmission facility, including PDF via email) signature page in the original and duplicate originals of this Agreement.
