 instructions on how to vote your shares of Company stock
and your control number.

If you hold shares in street name, you should complete, sign and date
the GOLDvoting instruction form provided to you by your bank, broker or other nominee. The availability of online or phone voting
may depend on the voting process of the organization that holds your shares. Beneficial owners who want to attend and also vote at the
Annual Meeting will need to obtain a legal proxy, in PDF or Image (gif, jpg or png) file format, from the organization that holds their
shares giving them the right to vote their shares at the Annual Meeting. Holders who wish to attend and/or vote at the Annual Meeting
must pre-register at least 24 hours prior to the Annual Meeting at www.cesonlineservices.com/dvax25_vm.

Whether your proxy is submitted by mail, telephone, mobile device or
online, your shares will be voted in the manner you instruct on your GOLDproxy card. If you submit a GOLDproxy card but
do not specify in your GOLDproxy card how you want your shares voted, they will be voted according to the Board’s recommendations
below:

What does it mean if I receive more than one proxy card?

Many of our stockholders hold their shares in more than one account
and may receive separate proxy cards or voting instructions forms for each of those accounts. If you receive more than one GOLDproxy
card, your shares are registered in more than one name or are registered in different accounts. Please sign, date and return or otherwise
submit your proxy with respect to each GOLDproxy card you receive to ensure that all of your shares are voted.
