FRONTIER BUILDING PRODUCTS PACIFIC, INC. (#2026169)

Form 2366 (02/11) Blanket Additional Insured Endorsement This endorsement modifies insurance provided by the Commercial Auto Policy, Motor Truck Cargo Legal Liability Coverage Endorsement, and/or Commercial General Liability Coverage Endorsement, as appears on the declarations page. All terms and conditions of the policy apply unless modified by this endorsement. If you pay the fee for this Blanket Additional Insured Endorsement, we agree with you that any person or organization with whom you have executed a written agreement prior to any loss is added as an additional insured with respect to such liability coverage as is afforded by the policy, but this insurance applies to such additional insured only as a person or organization liable for your operations and then only to the extent of that liability. This endorsement does not apply to acts, omissions, products, work, or operations of the additional insured. Regardless of the provisions of paragraph a. and b. of the “Other Insurance” clause of this policy, if the person or organization with whom you have executed a written agreement has other insurance under which it is the first named insured and that insurance also applies, then this insurance is primary to and non-contributory with that other insurance when the written contract or agreement between you and that person or organization, signed and executed by you before the bodily injury or property damage occurs and in effect during the policy period, requires this insurance to be primary and non- contributory. In no way does this endorsement waive the “Other Insurance” clause of the policy, nor make this policy primary to third parties hired by the insured to perform work for the insured or on the insured’s behalf. ALL OTHER TERMS, LIMITS, AND PROVISIONS OF THE POLICY REMAIN UNCHANGED. M_CL POLICY NUMBER: 991141819 Docusign Envelope ID: AA9A7CC3-A9B9-47D8-A802-F89481667D21
