<DIV align="left" style="font-size: 10pt; margin-top: 10pt">Thank you for your letter of October&nbsp;30, 2009, in which you provide comments on the Company&#146;s Form
40-F for the fiscal year ended December&nbsp;31, 2008, filed on April&nbsp;1, 2009 (the &#147;Form&nbsp;40-F&#148;).
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 10pt">We are pleased to provide the following responses to your comments. For ease of reference, we have
numbered our responses to correspond to your comments, as set out in your October&nbsp;30, 2009, letter.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 10pt"><U>Certifications Required by Rule&nbsp;13a-14(a) or Rule&nbsp;15d-14(a)</U>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 10pt">1.&nbsp;We confirm that the inclusion of our Principal Executive Officer&#146;s and Chief Financial
Officer&#146;s titles in the introductory paragraphs of our certifications was not intended to limit the
capacity in which such individuals provided the certifications. We have eliminated these title
references in the introductory paragraph in the revised certifications that are included in the
Amendment No.&nbsp;1 to the Form 40-F (the &#147;Amendment&#148;) that is being filed concurrently with this
letter.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 10pt">2.&nbsp;The exclusion of the language regarding internal control over financial reporting from the
introduction of paragraph four of our certifications was an inadvertent mistake. We have modified
the language in the revised certifications included in the Amendment to be in the exact form set
forth in General Instruction Item&nbsp;B(6)(a) of Form 40-F.

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 10pt">Please note that the Company&#146;s Principal Executive Officer at the time the Form 40-F was filed was
E. Peter Farmer, who was the Chief Executive Officer at that time. Mr.&nbsp;Farmer resigned effective
April&nbsp;30, 2009. The Principal Executive Officer of the Company currently is Ron F. Hochstein, who
holds the offices of President and Chief Executive Officer. At the time of filing the Form 40-F,
Mr.&nbsp;Hochstein was President of the Company. Based on discussions that our outside counsel, Mr.
William Wiese, had with Mr.&nbsp;Parker Morrill at the SEC, we are filing a revised certification of the
Principal Executive Officer of the Company from Mr.&nbsp;Hochstein. The Chief Financial Officer (who is
Mr.&nbsp;James R. Anderson) has not changed since filing the Form 40-F, so he is also signing the
revised certifications included in the Amendment.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 10pt">We hope that the foregoing responses adequately address the SEC&#146;s comments on the Form 40-F. We
would be pleased to address any questions you may have on the foregoing or any further comments you
may have. I can be reached at (416)&nbsp;979-1991, ext. 235.
