Inc. (the &#147;Company&#148;) greatly values the services that you provide to the
Company.&#160; Accordingly, the Company wishes
to provide you with a retention bonus payable to you in the event of the sale
of the Company to Energy<i><font style="font-style:italic;">Solutions</font></i>,
subject to the terms and conditions of this letter.&#160; </font></b></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="margin:0in 0in .0001pt;text-indent:1.0in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">You shall be
entitled to receive from the Company a retention bonus in the amount of
($100,000) (the &#147;Retention Bonus&#148;) from the Company for services rendered to
the Company and its affiliates during the three month period following the
closing date of the Sale (the &#147;Retention Period&#148;), if the closing date of the
Sale occurs prior to December 31, 2006, and you remain employed by the Company,
its successor, or any affiliate of the Company or its successor during the
Retention Period; provided, however, that if the closing date of the Sale
occurs during the term of this letter agreement but the agreement providing for
the Sale is terminated, you will be entitled to the Retention Bonus if you
remain employed by the Company, its successor, or any affiliate of the Company
or its successor during the three month period following the termination of the
agreement.&#160; The Retention Bonus shall be
paid as soon as is reasonably practical following the last day of the Retention
Period or three months after termination of the agreement providing for the
Sale, and is subject to such deductions as are required by law and applicable
regulations. Notwithstanding the foregoing, you shall be eligible for the
Retention Bonus even if you undergo a termination of employment during the
Retention Period or the three month period after termination of the agreement
providing for the Sale, if such termination of employment is by the Company
other than for Cause or by you for Good Reason.</font></p>
