3.5.2 Any Document properly transmitted pursuant to this Agreement

proceedings, will be admissible as between the parties to the same

extent and under the same conditions as other business records

originated and maintained in documentary form. Neither party shall

contest the admissibility of copies of Signed Documents under either the

business records exception to the hearsay rule or the best evidence rule

on the basis that the Signed Documents were not originated or maintained

in documentary form.
