The pricing date is also expected to be July 9, 2024, unless the Firm Tender Offer is extended.

In addition, the Issuer authorized two conditional cash tender offers to follow the Firm Tender Offer, provided certain conditions are met. If during the applicable measurement periods, as described in the Agreement, the Issuer’s common shares trade at an average discount to NAV of more than 7.5% (based upon the average of the difference between its volume-weighted average market price and NAV each business day during the period), the Issuer will conduct up to two additional tender offers, each for up to 5% of the Issuer’s then-outstanding common shares at 98% of NAV per share.
