This Agreement may be executed in any number of counterparts, and with respect to any Subscriber, by execution of an Omnibus Signature Page to this Agreement and the Subscription Agreement, each of which shall be enforceable against the parties actually executing such counterparts, and all of which together shall constitute one instrument. 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 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 facsimile or e-mail of a .pdf signature page were an original thereof.
