 respect to Proposal 1, your proxy will be voted “FOR” each of the four Board Nominees.

Can I use the GOLD proxy card if I want to vote for one or more of the Deep Track Nominees?

Yes, if you would like to vote in favor of some or all of the
Deep Track Nominees despite the Board’s recommendation to the contrary, we urge you to use the Company’s GOLDproxy
card or GOLDvoting instruction form to do so.

What happens if Deep Track withdraws or abandons its solicitation or fails to comply with the universal proxy rules and I already granted proxy authority in favor of Deep Track and its director nomination slate?

Stockholders are encouraged to submit their votes on the GOLDproxy card. If Deep Track withdraws or abandons its solicitation or fails to comply with the universal proxy rules after a
stockholder has already granted proxy authority, stockholders can still sign and date a later submitted GOLDproxy card.

If Deep Track withdraws or abandons its solicitation or fails
to comply with the universal proxy rules, any votes cast in favor of the Deep Track Nominees will be disregarded and not be counted,
whether such vote is provided on the Company’s GOLDproxy card or Deep Track’s white proxy card.

How will voting on any other business be conducted?

We do not know of any business or proposals to be considered
at the Annual Meeting other than the items described in this proxy statement. If any other business properly comes before the
Annual Meeting, the signed proxies received from you and other stockholders give the persons voting the proxies the authority
to vote on the matter according to their judgment.

What is a broker non-vote?

If you own shares through a broker in street name, you may
instruct your broker how to vote your shares. A “broker non-vote” occurs when you fail to properly provide your broker
with voting instructions, and the broker does not have the discretionary authority to vote your shares on a particular proposal
because the proposal is not a “routine” matter under applicable rules. To the extent that Deep Track provides a proxy
card or voting instruction form to stockholders who hold their shares in street name, all of the proposals presented at the Annual
Meeting will be considered “non-routine” matters, and brokers will not have discretionary voting authority to vote
on any of the proposals presented at the Annual Meeting. If, however, you are a stockholder who holds your shares in street name
