Dear Dollar Tree Inc. Shareowner:

VOTE “FOR” PROPOSAL #2 TO DECLASSIFY THE BOARD AT DOLLAR TREE

We are writing to urge you to vote FOR Proposal #2 at Dollar Tree Inc’s June 18, 2009 annual meeting of shareowners. CalPERS is the nation’s largest public pension fund with approximately $165 billion in assets and as of record date April 17, 2009, CalPERS owned approximately 73,150 shares of Dollar Tree common stock. Proposal #2 urges the Board to eliminate the present “classified board” structure, and give shareowners the right to elect all directors each year. We believe that a declassified board structure will promote board accountability and a culture focused on creating long-term value. CalPERS urges Dollar Tree shareowners to vote “FOR” Proposal #2.

LACK OF BOARD ACCOUNTABILITY & SHAREOWNER CONCERN

● In 2008, shareowners overwhelmingly supported a proposal to declassify the company’s board of directors. This proposal, identical to proposal #2 on the proxy card this year, received the support of shareowners representing 67.72% of the shares outstanding. Despite the strong support of shareowners, the classified board remains in place.

● Shareowners remain concerned about the company’s continued lack of meaningful response to investor wishes regarding the past shareowner proposal. On February 6, 2009, CalPERS was one of 21 investor signatories to a Council of Institutional Investors’ letter urging Dollar Tree to address board declassification consistent with majority shareowner support in 2008 [letter attached].

2009 DIRECTOR WITHHOLD VOTES AT DOLLAR TREE

We have had numerous conversations and ongoing dialogue with Lead Director Thomas Saunders and CEO Bob Sasser, and are convinced that they will once again ignore the majority of shareowners; regardless of the level of support that proposal #2 receives this year. The past behavior of Dollar Tree’s board does not warrant our support and we intend to withhold vote against the election of the following nominees: J. Douglas Perry, Thomas A. Saunders III, and Carl P. Zeithaml for failure to implement a majority passed shareowner proposal to declassify the board – and we urge you to do the same. We are supporting nominee Arnold S. Barron as a newly added Dollar Tree board member last year.

Please support this important initiative by voting FOR Proposal #2, and withhold vote against nominees Perry, Saunders, and Zeithaml.

Dear Mr. Brock:

On behalf of the Council of Institutional Investors and the undersigned member funds, I am writing to urge the Dollar Tree board to adopt the recommendations in a shareowner proposal that received majority support at the company’s 2008 annual meeting.

The Council is a not-for-profit association of 140 public, corporate and union pension funds with total assets that exceed $3 trillion. This is the Council’s second letter to you about this matter. We are disappointed that we have not received a response to our letter dated October 28, 2008, and that a review of Dollar Tree’s filings with the Securities and Exchange Commission and other reports suggests that the company has not acted on the proposal.

As you are aware, the proposal asking Dollar Tree to repeal the classified board won a majority of the votes cast for and against. The Council’s calculations exclude abstentions and broker non-votes.

As fiduciaries of pension plans, Council members are concerned about corporate performance and believe that boards should respond to majority-vote-winning shareowner proposals by adopting the recommended actions.

The Council and concerned members below urge the board to conduct a thoughtful and balanced analysis of the issues raised by the majority-vote-winning shareowner resolution. A committee of independent directors should perform the initial review. Senior management should not be involved. Council members encourage the board or committee to seek expert advice on the pros and cons of the measure.

Please share this letter with the full board. We look forward to your response, which will be posted on the Council’s Web site (www.cii.org). Please contact Council Analyst Laurel Leitner at (202) 261-7086 with any questions.

Sincerely,

Ann Yerger

Executive Director

Council of Institutional Investors
