 nominees. After careful consideration, your Board does not endorse any of the four Deep Track nominees and unanimously recommends you only vote “FOR” each of the Board’s nominees for election (Brent MacGregor, Scott Myers, Lauren Silvernail and Elaine Sun) and as recommended by your Board on all other proposals using the enclosed GOLD proxy card.

Your engagement and feedback are invaluable to us, and we appreciate your
trust and investment in Dynavax. On behalf of the entire Board of Directors and our Executive Leadership Team, we thank you for your support
and look forward to our continued success.

Chairman of the Board of Directors

You may receive proxy solicitation materials from Deep Track
or other persons or entities affiliated with Deep Track, including an opposition proxy statement and associated white proxy
card or white voting instruction form. The Board urges you to disregard such materials and NOT to vote using the associated
white proxy card or white voting instruction form. If you have already voted using Deep Track’s white proxy card or white voting instruction form, you
have every right to change your vote and revoke your prior proxy before it is exercised by signing and dating the enclosed GOLDproxy
card and returning it by mail in the postage-paid envelope provided, by voting via the internet, or by telephone by following
the instructions provided on the enclosed GOLDproxy card. We are not responsible for the accuracy of any information
provided by or relating to Deep Track or its nominees contained in solicitation materials filed or disseminated by or on
behalf of Deep Track or any other statements Deep Track may otherwise make.

PLEASE NOTE THAT THIS YEAR, YOUR GOLD PROXY CARD LOOKS DIFFERENT FROM IN YEARS PAST. THE SECURITIES AND EXCHANGE COMMISSION RECENTLY ADOPTED PROXY RULES THAT REQUIRE THE COMPANY’S GOLD PROXY CARD TO LIST NOT ONLY OUR BOARD OF DIRECTORS’ FOUR (4) NOMINEES BUT ALSO THE FOUR (4) DEEP TRACK NOMINEES. OUR BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” THE ELECTION OF ONLY EACH OF THE BOARD’S FOUR (4) RECOMMENDED NOMINEES (BRENT MACGREGOR, SCOTT MYERS, LAUREN SILVERNAIL AND ELAINE SUN), “FOR” PROPOSALS 2, 3 AND 4, AND “AGAINST” PROPOSAL 5, IN EACH CASE USING THE ENCLOSED GOLD PROXY CARD.
