(NASDAQ:SPAR) DATE: August 19, 1998 RE: Spartan Motors' Affiliate Carpenter Industries, Inc. We wanted to inform shareholders of the current status of Spartan Motors' one-third-owned equity affiliate Carpenter Industries, Inc. As the attached release discusses, Carpenter's shareholders including Spartan Motors have agreed to pursue a plan that could help get Carpenter back on track. We, as shareholders, are asking for Carpenter's vendors and dealers to participate in this initiative and are hopeful the result will be resumed production and an improved financial condition at Carpenter. Though we remain optimistic, we also must be realistic. If Carpenter's vendors and dealers do not agree to participate in the restructuring plan satisfactory to Spartan, then Spartan will be forced to consider a termination of our participation in Carpenter Industries.
