Without derogating from the generality of the above, Sellers specifically agree to (i) maintain all such information in strict confidence; (ii) not disclose the information to any third parties; (iii) not use the information for any purpose except for delivering the ordered work; and (vi) not to copy or reproduce any of the information without the Buyer’s permission.
