        <footnote id="F1">Includes 691 deferred stock units (DSUs) which were inadvertently omitted from the reporting person's initial Form 3.  Each DSU is the economic equivalent of one share of the Issuer's common stock. The DSUs vested immediately upon issuance on April 30, 2012; however, the underlying common shares will not be issued to the reporting person, and the reporting person shall not have any voting or dispositive rights with respect to the underlying common shares, until termination of the reporting person's employment or services as a director of NovaGold Resources Inc. The grants will expire no later than 90 days after the reporting person's termination date.</footnote>
