Dayton Superior Reports Extension of Debt Refinancing Commitment

DAYTON, Ohio--(BUSINESS WIRE)--Dayton Superior Corporation (NASDAQ: DSUP), the leading North American provider of specialized products for the non-residential concrete construction market, today announced that it has extended its commitment from GE Commercial Finance for a debt refinancing to February 29, 2008. Dayton Superior expects to complete the refinancing prior to that date. The commitment is for a new $150 million revolving credit facility and a new $100 million term loan, for total new financing of $250 million.

The refinancing is currently estimated to reduce annual interest expense by $5 million to $6 million, or approximately $0.25 to $0.30 per share. The new "revolver," an Asset Based Lending facility currently expected to be issued at the rate of LIBOR plus 225 basis points, will replace the Company’s existing $130 million revolving credit facility. A portion of the revolving credit facility, as well as the new term loan, which is currently expected to be issued at LIBOR plus 375 basis points, will be used to retire the Company’s 10¾% Senior Second Secured Notes due in September 2008 at a redemption price of 102.813% of principal amount plus accrued interest.

Consummation of the new debt financing is subject to customary conditions, including an absence of material adverse changes in Dayton Superior's business and a requirement for minimum adjusted EBITDA, as defined.

The terms of the new debt remain unchanged and are contained in the Exhibits to the Company’s Form 10-Q for the third quarter of 2007.

Dayton Superior expects to explore refinancing alternatives with respect to its 13% Senior Subordinated Notes soon after completion of the refinancing of the 10¾% Senior Second Secured Notes.
