<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;This Performance Share Unit Award Agreement (&#147;Agreement&#148;) is entered into effective as of
January&nbsp;27, 2006 the &#147;Grant Date&#148;), by and between Waste Management, Inc., a Delaware corporation
(together with its Subsidiaries and Affiliates, the
&#147;Company&#148;), and &#60;&#60; Full_NameFirst&#62;&#62; (the &#147;Employee&#148;), pursuant to
the Waste Management, Inc. 2004 Stock Incentive Plan (the &#147;Plan&#148;). Employee and the Company agree
to execute such further instruments and to take such further action as may reasonably be necessary
to carry out the intent of this Agreement.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.&nbsp;<U>Grant.</U> In accordance with the terms of the Plan, the Company hereby grants to
Employee a Performance Share Unit Award (the &#147;Award&#148;) subject to the terms and conditions set forth
herein. Performance Share Units are notational units of measurement denominated in shares of
common stock of Waste Management, Inc., $.01 par value, (&#147;Common Stock&#148;), subject to the conditions
and restrictions on transferability set forth below and in the Plan.

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 3%">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The &#147;Performance Period&#148; for this Award shall be the 36-month period commencing on
January&nbsp;1, 2006 and ending on December&nbsp;31, 2008. The Award shall be subject to performance
vesting requirements based upon the achievement of the Performance Target specified below,
subject to certification of the degree of achievement of such Performance Target by the
Committee pursuant to Section&nbsp;7 of the Plan.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 3%">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) The measurement tool for determining level of achievement shall be the average
Return on Invested Capital (&#147;ROIC&#148;) for the 36-month period beginning January&nbsp;1, 2006 and
ending December&nbsp;31, 2008. ROIC is defined to mean (i)&nbsp;the Company&#146;s average &#147;as reported&#148;
Net Operating Profit After Taxes (&#147;NOPAT&#148;) for the Performance Period, divided by (ii)&nbsp;the
Company&#146;s average Invested Capital for the Performance Period. For purposes of this
Agreement, the average ROIC for the Performance Period will be calculated using the
following equation:
