Valero halted the operations at the refinery in November. The company has agreed
that no removal of process equipment will take place while negotiations are under way.

In November last year, Valero Energy shut down its Delaware City refinery due to financial
losses caused by very poor economic conditions, significant capital spending requirements and
high operating costs.

Bill Klesse, chairman and CEO of Valero, said: “We have worked very closely with Gov.
Markell, who has been instrumental in furthering these negotiations.”

Valero said that there is
no specific timetable when negotiations might be completed.
