This Bill of Sale may be executed simultaneously in counterparts (including by means of facsimile or portable document format (pdf) signature pages), any one of which need not contain the signatures of more than one party hereto, but all such counterparts taken together shall constitute one and the same instrument. This Bill of Sale, to the extent signed and delivered by means of a facsimile machine or electronic transmission in portable document format (pdf), shall be treated in all manner and respects as an original thereof and shall be considered to have the same binding legal effects as if it were the original signed version thereof delivered in person. At the request of any party hereto, the other party shall re-execute original forms hereof and deliver them to the other parties. No party hereto shall raise the use of a facsimile machine or electronic transmission in portable document format (pdf) to deliver a signature or the fact that any signature or document was transmitted or communicated through the use of a facsimile machine or electronic transmission in portable document format (pdf) as a defense to the formation of a contract, and each such party forever waives any such defense.
