This Agreement may be executed in any number of counterparts, including counterparts transmitted by facsimile or electronic mail, any one of which shall constitute an original of this Agreement. When counterparts or facsimile or electronic mail copies have been executed by all parties hereto, they shall have the same effect as if the signatures to each counterpart or copy were upon the same documents and copies of such documents shall be deemed valid as originals. The parties agree that all such signatures may be transferred to a single document upon the request of any party. This Agreement shall not be binding unless and until it shall be fully executed and delivered by all parties hereto.  In the event that this Agreement is executed and delivered by way of facsimile transmission or electronic mail, each party delivering a facsimile or electronic mail counterpart shall promptly deliver an ink-signed original counterpart of the Agreement to the other party by overnight courier service; provided that the failure of a party to deliver an ink-signed original counterpart shall not in any way effect the validity, enforceability or binding effect of a counterpart executed and delivered by facsimile transmission or electronic mail.
