Approval</font></b></p>

<p style="background:white;margin:0in 0in .0001pt;"><font size="2" face="Arial" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="background:white;margin:0in 0in .0001pt;"><b><font size="2" face="Arial" style="font-size:10.0pt;font-weight:bold;">Calgary,
Alberta (July&nbsp;21, 2009)</font></b><font size="2" face="Arial" style="font-size:10.0pt;"> - Suncor Energy Inc. (TSX:SU) (NYSE:SU) and Petro-Canada (TSX:PCA) (NYSE:PCZ)
announced today that the Competition Bureau has approved the proposed merger of
Suncor and Petro-Canada.</font></p>

<p style="background:white;margin:0in 0in .0001pt;"><font size="2" face="Arial" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="background:white;margin:0in 0in .0001pt;"><font size="2" face="Arial" style="font-size:10.0pt;">The approval is
reflected in a consent agreement with the Competition Bureau which will be
registered with the Competition Tribunal in Ottawa. Under the consent agreement
the companies have agreed to take steps to maintain retail and wholesale
competition in Ontario, including divesting 104 retail locations, and entering
into certain supply and throughput arrangements in Ontario for a period of 10
years.</font></p>

<p style="background:white;margin:0in 0in .0001pt;"><font size="2" face="Arial" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="background:white;margin:0in 0in .0001pt;"><font size="2" face="Arial" style="font-size:10.0pt;">With all the conditions
necessary to complete the merger satisfied, Suncor and Petro-Canada intend to
make the merger effective August&nbsp;1, 2009.</font></p>

<p style="background:white;margin:0in 0in .0001pt;"><font size="2" face="Arial" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="background:white;margin:0in 0in .0001pt;"><font size="2" face="Arial" style="font-size:10.0pt;">&#147;The Bureau&#146;s
review process was very intensive and thorough,&#148; said Rick George, who is
currently president and chief executive officer of Suncor and will assume the
same role in the merged company. &#147;We are satisfied that the resulting terms
will preserve the expected benefits of the merger and maintain a competitive
refined products market in Ontario.&#148;</font></p>

<p style="background:white;margin:0in 0in .0001pt;"><font size="2" face="Arial" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="background:white;margin:0in 0in .0001pt;"><font size="2" face="Arial" style="font-size:10.0pt;">&#147;With this major
milestone behind us, our focus now is to get the final pieces in place to close
the deal and launch what will be Canada&#146;s premier energy company,&#148; said George.</font></p>
