Section 3. Transaction Terms. (Continued)

3.3. Validity and Enforceability.

3.3.1. This Agreement has been executed by the parties to

evidence their mutual intent to create binding obligations pursuant to the

electronic transmission and receipt of Documents specifying certain of the

applicable terms.

3.3.2. Any Document properly transmitted pursuant to this

Agreement shall be considered to be a "writing" or "in writing"; and any

such Document when containing, or to which there is affixed, a Signature

Code ("Signed Document") shall be deemed for all purposes to have been

"signed" and to constitute an "original" when printed from electronic

files or records established and maintained in the normal course of

business.

3.3.3. The parties agree not to contest the validity or

enforceability of any Signed Document under the provisions of any

applicable law relating to whether certain agreements are to be in writing

or signed by the party to be bound thereby. Signed Documents, if

introduced as evidence on paper in any judicial, arbitration, mediation or

administrative 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

documentary form.
