Dear Shareholder:

I am writing to you directly to request your assistance. BlackRock California Investment Quality Municipal Trust Inc. (NYSE Amex: RAA) is asking its shareholders to approve the proposed reorganization of RAA into BlackRock California Municipal Income Trust (NYSE: BFZ). As more fully explained in the Joint Proxy Statement/Prospectus which accompanied our original mailing, we believe that the reorganizations will benefit each fund's shareholders.

Each fund's Board of Directors has unanimously approved the reorganization.

We recently mailed you proxy materials relating to proposals to be voted on at the November 30, 2009 Joint Special Shareholder Meeting but our records indicate that we have not received your vote. In order to avoid incurring further expenses by the funds, we are asking you to take a moment to submit your vote.

You can vote quickly and easily using one of the following methods:

· Speak to a live Proxy Specialist by calling 1-866-704-4427. We can answer any of your questions and record your vote. (Open: M-F 9am - 11 pm, Sat 12pm - 6pm EST)

· Mail in your signed proxy card in the envelope provided.

· Call the phone number on the proxy card and enter the control number printed on the card and follow the touchtone prompts.

· Log on to the website noted on your proxy card, enter your control number printed on the card and vote by following the on-screen prompts.

Every vote counts!

The Joint Proxy Statement/Prospectus relating to the proposed reorganization contains important information and shareholders are urged to read it. Free copies of the Joint Proxy Statement/Prospectus are available by calling BlackRock at (800) 882-0052 or on the Securities and Exchange Commission's web site at www.sec.gov .

Thank you for your help with this important matter.

Sincerely,

/s/ Anne F. Ackerley

Anne F. Ackerley

President and Chief Executive Officer
