Sets Date of Second-Quarter 2010 Earnings Release and Conference Call

Toronto, Ontario — July 2, 2010 — IESI-BFC Ltd. (“IESI-BFC”) (NYSE, TSX: BIN) and Waste Services, Inc. (“WSI”) (NASDAQ: WSII) today announced that they have completed their merger which establishes North America’s third largest solid waste management company. The combined company, which will be headquartered in Toronto, will continue as IESI-BFC Ltd. and trade under the ticker symbol “BIN” on the New York and the Toronto Stock Exchanges.

The merged company will have more than 6,000 employees serving commercial, industrial and residential customers in 11 U.S. states and the District of Columbia, and in six Canadian provinces.  The transaction is expected to generate US$25-30 million in net pre-tax annual run rate synergies by the end of the second year following closing.

Under the terms of the agreement, WSI shareholders will receive 0.5833 common shares of IESI-BFC for each WSI common share held.  The 28.0 million common shares that IESI-BFC is issuing to WSI represent approximately 23.0% ownership in the combined company, assuming conversion of IESI-BFC’s Participating Preferred Shares (“PPSs”). At close, IESI-BFC’s total number of outstanding common shares and PPSs is 121.4 million.

The combined company will be led by Keith Carrigan, IESI-BFC’s current Vice Chairman and Chief Executive Officer.  Thomas Cowee, Vice President and Chief Financial Officer of IESI-BFC, will continue in his current role.

“Today, in completing our transaction with WSI, we have advanced to a top-three position in the North American non-hazardous solid waste management industry,” said Keith Carrigan, Vice Chairman and Chief Executive Officer of IESI-BFC. “We look forward to benefiting from the synergies that will result from our combination and creating additional future value for shareholders. We expect the combination to generate additional free cash flow, giving us the ability to deliver shareholder value through several avenues, including the ongoing payment of our regular quarterly dividend. We are very excited to begin this new phase for IESI-BFC and remain committed to delivering excellent customer service, environmental stewardship, and community support.”
