premise: 4. EXCLUSIONS.  Information that Recipient can establish:  (a) was lawfully in Recipient's possession before receipt from Discloser without any confidentiality obligation attached thereto; or  (b) is or becomes a matter of public knowledge through no fault of Recipient; or  (c) was independently developed or discovered by Recipient without use of any Confidential Information obtained from Discloser, shall not be considered Confidential Information under this NDA.  Additionally, it shall not be considered a breach of this NDA if Recipient discloses Confidential Information if and only to the extent:  (i) it is required to do so by law provided that Recipient gives Discloser sufficient notice to enable it to seek an order limiting or precluding such disclosure; or  (ii) Discloser gives its prior written authorization to do so which is signed by an officer of the Discloser, provided that Recipient complies with the disclosure parameters set forth in such authorization. 5. RETURN OF CONFIDENTIAL INFORMATION.  At the Discloser’s request, the Recipient shall promptly return any or all Confidential Information received from the Discloser (including, without limitation, any summaries or copies or Confidential Information) or will certify through an officer of the Recipient that all Confidential Information received from the Discloser, and any summaries or copies thereof, have been destroyed.  For greater certainty, failure of the Discloser to make such request of Recipient shall not entitle Recipient to make any further use of the Confidential Information or otherwise extend Recipient’s rights set forth herein after expiration or termination of this NDA and Recipient specifically agrees to cease any further use of Discloser’s Confidential Information in such event. 6. NO RESTRICTIONS ON GENERAL KNOWLEDGE.  The Participant acknowledges that Magnet Forensics may develop information internally, or receive information from other parties, that is similar to their Confidential Information.  Nothing in this NDA shall prohibit Magnet Forensics from developing products, concepts, systems or techniques that are similar to or compete with the products, concepts, systems or techniques contemplated by or embodied in the Participant’s Confidential Information provided that Magnet Forensics does not violate any of its obligations under this NDA.
