Notwithstanding the foregoing, unless a Member designates in writing that the Data in question cannot be shared or that such sharing is subject to stated restrictions, all Data provided by Members may be shared with MS-ISAC’s federal partners (including, without limitation, the U.S. Department of Homeland Security), and may be shared with other MS-ISAC members provided that the Data is anonymized and not attributable to Member.

If an MS-ISAC Member is unable to delete the Data based on applicable law, then that Member will continue to maintain the confidentiality of the Data consistent with the TLP designation assigned to the Data. 
  3. Demand for Data. If any third party makes a demand for any Data, the MS-ISAC or any other Member receiving such a demand shall immediately forward such request to the Member who shared the Data and consult and cooperate with that Member and will make reasonable efforts, consistent with applicable law and the applicable TLP designation, to protect the confidentiality of the Data.  The Member sharing the Data will, as needed, have the opportunity to seek judicial or other appropriate avenues of redress to prevent any release.
