In Kemmeter v. McDaniel Backhoe Service, 89 Ohio St.3d 409, 413, 2000 Ohio 209, 732 N.E.2d 385, the Ohio Supreme Court stated as follows: "The necessary corollary to a prohibition of indemnifying a promissee's negligence is a prohibition of the indemnification of costs associated with a promisee's alleged negligence. If a plaintiff alleges negligence against a promissee, a promisor may not agree to undertake the defense costs the promisee incurs in defending itself against claims regarding its own negligence." Id.
