You will be able to attend the Special Meeting, as well as vote and submit your questions during the live webcast of the meeting, by visiting www.virtualshareholdermeeting.com/ GLAD2023SM. Our records indicate that we have not yet received voting instructions for your account.

Your vote is urgently needed. We appreciate your investment and encourage you to cast a vote for this year’s Special meeting. We urge you to vote as soon as possible to ensure our ability to conduct necessary business. The Board of Directors of GLAD recommends that you vote “FOR” the New Advisory Agreement.

Regardless of the number of shares you own, your vote is very important and will help us avoid additional solicitation costs. Please note that proxy solicitation costs are borne by the company and its stockholders. These costs can be substantial. Voting today will help us manage such costs and will avoid the need to initiate further calls or mailings to you. We urge you to vote as soon as possible to allow GLAD to reconvene the adjourned meeting as soon as possible.
