This Amendment may be executed in one or more counterparts, each of which when so executed shall be deemed to be an original, but all of which when taken together shall constitute one and the same instrument. Delivery of an executed counterpart of this Amendment by facsimile or portable document format (pdf) shall be equally as effective as delivery of an executed original counterpart and shall constitute a covenant to deliver an executed original counterpart, but the failure to do so shall not affect the validity, enforceability and binding effect of this Amendment.
