Dear Stockholder:


We recently mailed to you a proxy statement of Waste Connections, Inc. (“Waste Connections”). Your support is requested for the proposals to be voted upon at the May 26 special meeting of stockholders. As of the date of this letter your shares of Waste Connections remain unvoted.


The Waste Connections board of directors unanimously recommends that stockholders vote “FOR” each of the proposals being submitted to a vote at the Waste Connections special meeting.


Please Vote Your Waste Connections Shares Today!


Regardless of the number of shares you own your vote is very important. We encourage all stockholders to have their voices heard. The adoption of the merger agreement and approval of the merger requires the affirmative vote of the holders of a majority of the outstanding shares of Waste Connections common stock entitled to vote on the proposal. Failure to vote and a vote to abstain will have the same effect as a vote against the proposal to adopt the merger agreement and approve the merger.


There are three ways to vote your shares of Waste Connections without attending the special meeting in person – each only taking a few moments:


·By Telephone – Stockholders in the United States can submit their vote by calling the toll-free number indicated on the enclosed vote instruction form; please have your control number located on the enclosed vote instruction form available when calling;
·By Internet – Stockholders can submit their vote via Internet at www.proxyvote.com; please have the control number located on the enclosed vote instruction form available; or
·By Mail – Stockholders can vote by mail by signing, dating and returning the enclosed vote instruction form in the postage-paid envelope provided.


To be valid, your vote by telephone or internet must be received by 11:59 p.m. (Eastern Time) on May 25, the day preceding the special meeting.


If you need assistance in voting your shares or have questions regarding the special meeting, please contact Waste Connections’ proxy solicitor, MacKenzie Partners, Inc., at (800) 322-2885 (toll-free) or (212) 929-5500 (collect), or email at proxy@mackenziepartners.com.


We thank you for your continued support of Waste Connections, Inc.
