premise: Having acknowledged that it, particularly within a networked environment, the return and/or destruction of electronically stored information may be impossible, extremely or otherwise unduly difficult or costly, the immediately preceding sentence is not intended to, and does not obligate the Receiving Party to make extra-ordinary efforts to destroy electronically stored copies of the Confidential Information, provided that, in relation to any such copy that is not destroyed the Receiving Party’s obligations of confidentiality and restricted use shall continue as per the provisions of this Agreement. 6.4. Notwithstanding Section 6.3, the Receiving Party may retain a reasonable number of copies of the Confidential Information (and any materials embedding the same) (“Retained Copies”) for the sole purpose of  (i) satisfying any legal or regulatory requirements regarding record and data retention that the Receiving Party is obligated to comply with;  (ii) enforcing this Agreement; and/or  (iii) archiving consistent with good business practices and the Receiving Party’s internal policies.  For the avoidance of doubt, the Receiving Party’s obligations of confidentiality and restricted use as set forth in this Agreement shall continue in respect of such Retained Copies as per the provisions of this Agreement. 6.5. Notwithstanding anything else in this Agreement, the Receiving Party’s obligations of confidentiality and restricted use hereunder shall continue in force during the term of this Agreement and shall survive for three (3) years following the expiration or termination of this Agreement or, in the case of trade secrets, until such time as the Confidential Information does not qualify as a trade secret.
