Waste Connections Announces Accelerated Vesting of Stock Options Combined With Resale Restriction Agreements
FOLSOM, Calif.

Waste Connections, Inc. today announced that on October 27, 2005, its Board of Directors accelerated the vesting of outstanding options previously awarded to employees. In addition, to prevent unintended benefits to executive officers and other selected corporate, regional and field employees, restrictions have been imposed on shares obtained through the accelerated vesting process. These restrictions prevent the sale of any shares acquired from the exercise of an accelerated option prior to the earlier of the original vesting date of the option, or the individual's termination of employment.

As a result of the accelerated vesting of stock options in advance of the effective date of Statement of Financial Accounting Standards (SFAS) No. 123R, "Share Based Payment," Waste Connections expects to reduce the pre-tax stock option expense it would otherwise be required to record by an estimated $8.5 million in 2006, $4.1 million in 2007, and $0.6 million in 2008. As a result of the acceleration, the Company expects to take a non-cash charge of approximately $16.2 million ($10.2 million net of taxes) in the fourth quarter of 2005 based on the closing price of the Company's stock on October 27, 2005.

Ronald J. Mittelstaedt, Chairman and Chief Executive Officer, said, "This acceleration will help improve the comparability of financial results for investors and analysts in future periods. More importantly, the restriction agreements for these accelerated options that we have entered into with more than 55 of our key employees prohibit any unintended benefits for these individuals in advance of the original vesting dates. These agreements cover approximately 80% of the options accelerated."
