"The Recipient will only have a duty to protect Confidential Information disclosed to it by the Discloser: (1) if it is clearly and conspicuously marked as “confidential” or with a similar designation; (2) if it is identified by the Discloser as confidential and/or proprietary before, during, or promptly after presentation or communication; or (3) if it is disclosed in a manner in which the Discloser reasonably communicated, or the Recipient should reasonably have understood under the circumstances that the disclosure should be treated as confidential, whether or not the specific designation “confidential” or any similar designation is used."
and
"Recipient may disclose Confidential Information solely as needed to comply with a court order, subpoena, or other government demand (provided that Recipient first used all commercially reasonable efforts to notify Discloser and to give Discloser the opportunity to challenge such court order, subpoena, or government demand except in situations where Recipient is prevented, per lawful government request, from disclosing the existence of the court order, subpoena, or other government demand)."
and
"Each party acknowledges that damages for improper disclosure of Confidential Information may be irreparable; therefore, the injured party is entitled to seek equitable relief, including temporary restraining order(s) or preliminary or permanent injunction, in addition to all other remedies, for any violation or threatened violation of this Section 8. A Recipient shall have a duty to protect Confidential Information during the term of this Agreement and for a period of five (5) years thereafter."
