The parties hereto recognize and agree that the information disclosed by either of the parties hereto may be proprietary and/or confidential information. In the event proprietary and/or confidential information is disclosed, it shall be conspicuously identified as such. To the extent that oral information is disclosed by either party, such oral information shall be deemed to be proprietary and/or confidential if it is reduced to written or other tangible form within fourteen (14) days of the oral disclosure and the written or other tangible form is conspicuously identified as proprietary and/or confidential. The parties acknowledge that such proprietary and/or confidential information is a valuable, special, and unique asset belonging to the party that discloses such information.

If any proprietary and/or confidential information is ordered produced or disclosed pursuant to subpoena or court order, the receiving party shall first give the disclosing party prompt notice of such request so that the disclosing party has an opportunity to defend, limit or protect against such production or disclosure. 8.
