This Agreement may be executed in several counterparts, each of which shall be deemed an original but all of which shall constitute one and the same instrument. All of such counterparts shall be read as though one, and they shall have the same force and effect as though all the signers had signed a single page. In the event that any signature is delivered by facsimile transmission or by an e-mail which contains a portable document format (.pdf) file of an executed signature page, such signature page shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such signature page were an original thereof.
