Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions (see General Instruction A.2. below):

Each of Stanadyne Holdings, Inc. (“Holdings”) and Stanadyne Corporation (“Stanadyne”) is filing this Current Report on Form 8-K to supplement the information previously reported on Form 8-K filed January 26, 2010 by Holdings and Stanadyne regarding the dismissal of Deloitte & Touche LLP (“Deloitte”) by each of Holdings and Stanadyne on January 20, 2010 as the registered public accounting firm of each of Holdings and Stanadyne. As previously reported, on January 15, 2010 Deloitte informed each of Holdings and Stanadyne, by notice to a director of each of Holdings and Stanadyne, that Deloitte had concluded that it was not currently independent with respect to Holdings or Stanadyne. Each of Holdings and Stanadyne understands from Deloitte that Deloitte had concluded that it was not currently independent with respect to Holdings or Stanadyne as a result of a communication to Deloitte from Kohlberg Capital Corporation on January 4, 2010 and that Deloitte’s conclusion did not relate to any action or activity of either of Holdings or Stanadyne. Investment funds associated with Kohlberg & Company, L.L.C. (“Kohlberg & Co.”) control each of Holdings and Stanadyne through their ownership of substantially all of the equity of Holdings, which owns 100% of Stanadyne’s parent company, Stanadyne Intermediate Holding Corp. Two of the directors of each of Holdings and Stanadyne are both partners of Kohlberg & Co. and directors of Kohlberg Capital Corporation. As reported by Kohlberg Capital Corporation in its public filings, these two directors also have an ownership interest in Kohlberg Capital Corporation. Each of Holdings and Stanadyne understands that Deloitte was independent of each of Holdings and Stanadyne during all periods covered by the previously issued financial statements of each of Holdings and Stanadyne with which Deloitte was associated as its registered public accounting firm and that Deloitte was independent when it performed its work and issued its audit reports.
