Supplemental Potential Party in Interest, it is not HCVT’s intent to construe such entity as an

affiliate of or entity related to such Supplemental Potential Party in Interest for purposes other

than the disclosures in the Declarations and HCVT reserves and preserves all rights with respect

to such disclosures.

2 Capitalized terms not defined herein are defined in the Application. HCVT does not waive the Application and its contents by this First Supplemental Declaration, and hereby reserves and preserves all privileges.

supplemental declarations.

I declare under penalty of perjury that the foregoing is true and correct to the best of my knowledge.
