Attn: General Counsel

Hi Dan-

Hope all is well with you. As per my voicemail on Monday, October 26th, I mentioned that the iShares exchange traded funds are conducting an important shareholder proxy as a result of BlackRock, Inc.’s acquisition of Barclays Global Investors, N.A., including Barclays Global Fund Advisors, the investment adviser to the iShares exchange traded funds (the “Transaction”). The Transaction is expected to close at the end of 2009.

It is our understanding that Allstate Insurance, as of recent SEC 13-F filings, is a substantial shareholder (approximately $225 million) in shares of the iShares MSCI Canada Fund (Ticker Symbol: EWC). The proxy vote results indicate that Allstate Insurance voted but “abstained” in relation to the proposal to approve the new investment advisory agreement for the iShares MSCI Canada Fund. An “abstention” has the same effect as a vote against the proposal to approve the new investment advisory agreement.

Currently, the iShares MSCI Canada Fund is short of the necessary shareholder vote required for the approval of the new investment advisory agreement.

We ask that you consider the above and understand the implications of your “abstention” vote on such an important proposal.

Please let me know if you have any questions.

Thank you.

Regards,

Paul
