BlackRock North American Income Trust plc (the "Company")

Issue of Equity

Further to the announcement on 28 November 2012, the Company announces that
1,500,000 new Ordinary shares of one pence each have been issued for cash at a
price of 102 pence per share and these shares have today been admitted to the
premium listing segment of the Official List of the UK Listing Authority and to
trading on the London Stock Exchange's main market for listed securities. The
new Ordinary shares are issued fully paid and rank pari passu with the existing
Ordinary shares.

In addition, the Company wishes to notify the market (as per DTR 5.6.1R) that,
as a result of the above allotment of Ordinary shares, the issued share capital
of the Company consists of 66,500,000 Ordinary shares.  Each Ordinary share
carries the right to one vote in relation to all circumstances at general
meetings of the Company.  The Company does not hold any Ordinary shares in
Treasury.

The above figure may be used by shareholders as the denominator for the
calculations by which they will determine if they are required to notify their
interest in, or a change to their interest in, the Company under the FSA's
Disclosure and Transparency Rules.
