shall not be affected thereby, and each remaining term, covenant or provision of this Order shall be deemed valid and enforced to the fullest extent permitted by law. 16. Indemnification: To the fullest extent permitted by law, Buyer shall defend, indemnify and hold Seller harmless from any and all claims, demands, subrogation claims by Buyer's insurers, causes of action, liabilities, fines, regulatory actions, seizures of product, losses, costs, expenses (including, but not limited to attorneys' fees, expert witness expenses and litigation expenses) (hereinafter "Claim"), arising from or in connection with any Claim asserted against Seller for any damage, injury, death, loss, property damage, environmental liability, or any other Claim, whether in tort, contract, or otherwise, relating to this Order, the business relationship between the parties or the goods provided hereunder. Notwithstanding the foregoing, Buyer has no indemnity obligation to Seller with respect to any Claims that result solely from the negligence of Seller and this indemnity provision does not purport to indemnify Seller solely for its own negligence, but rather for the negligence or conduct, whether sole or concurrent, of Buyer. Buyer, for itself and its insurers, expressly waives any and all limitations or liability caps, if any, on Buyer's contribution liability to Seller, and any and all statutory or common law lien rights or Claims against Seller arising from any applicable workers compensation or disability acts, which Buyer might or could assert against Seller or Seller's insurers in the event of the personal injury or death of Buyer's employees, representatives or servants. Without limiting the foregoing, Buyer, for itself and its insurers, also waives any liens, claims or other rights it may have as a result of being subrogated to any rights of its employees, representatives or servants. 17. Insurance: Buyer shall obtain comprehensive general liability coverage, including contractual liability coverage, naming Seller as an additional named insured, in amounts sufficient to fully protect Seller under this Agreement from loss, damage or casualty caused by Buyer or incurred by Seller under this Agreement. 18. Governing Law and Forum Selection: This agreement shall be governed by and subject to the internal laws (exclusive of the conflicts of law provisions) and decisions of the courts of the State of Illinois. The parties consent to the exclusive jurisdiction of the federal court in Chicago, Illinois or the state court located in DuPage County, Illinois with respect to all litigation, claims, causes of action, demands, Controversies (as defined herein) or disputes among the parties. The only exception to this forum selection provision is a claim by Seller seeking the replevin of the products in the event the courts specified in this provision will not or cannot assert jurisdiction. All counterclaims, if any, in connection with the replevin claim, shall be subject to this forum selection provision.
