Dear Dave:

     This letter is to memorialize our agreement that you have volunteered to reduce your annualized base salary by 15%, to $433,500. This agreement will constitute an amendment to your Employment Agreement which was executed by you on September 15, 2008 (the “Employment Agreement”). You explicitly acknowledge and agree that the reduction in your base salary has been completely voluntary and will not be considered a “Change in Terms of Service,” as defined in the Employment Agreement.

     Thank you for your continued service to Superior Well Services.

		Sincerely,
		/s/ Thomas Stoelk
ACCEPTED AND AGREED:
/s/ Dave Wallace
