Failure to Vote

The required vote to approve the Asset Sale Proposal
is based on the total number of shares of our common stock outstanding and entitled to vote thereon as of the close of business on the
record date, not just the shares that are voted at the Special Meeting. If you do not vote, it will have the same effect as a vote “Against”
the Asset Sale Proposal.

Since the required vote for the Advisory Compensation
Proposal and the Adjournment Proposal is a majority of the voting power of the shares of our common stock present in person or by proxy
at the Special Meeting and entitled to vote on the matter, the failure to vote your shares will not have an effect on the outcome of
those proposals.

A failure to vote will have the same effect as a vote “Against” the Asset Sale Proposal, but will have no impact on the outcome of the Advisory Compensation Proposal or the Adjournment Proposal.

Proxies; Revocation of Proxies
