This Agreement may be executed in any number of counterparts, each of which will be deemed an original and all of which, taken together, will constitute one instrument. Buyer and Seller may execute different counterparts of this Agreement and, if they do so, the signature pages from the different counterparts may be combined to provide one integrated document. Execution may be confirmed by exchange of signatures by telefacsimile or electronic mail transmission, and a telefaxed or emailed signature will have the same effect as an original.
