**THIS ENDORSEMENT CHANGES THE POLICY. PLEASE READ IT CAREFULLY.**

This endorsement modifies insurance provided under the following:

**ACE UMBRELLA PLUS™ COMMERCIAL UMBRELLA LIABILITY POLICY**

If this policy provides greater coverage, limits or conditions than any of the policies listed in the Schedule of Other Policies below (each such scheduled policy referred to as an Other Policy), then this policy will provide coverage for loss to the extent of the difference in the coverages, limits or conditions between this policy and the Other Policy, subject to the terms, limitations and conditions of this policy.

This policy provides such coverage on an excess basis for and only to the extent of any such difference in terms, limits and conditions. In no event will the coverage afforded under this policy, in combination with any one or more of such Other Policies, exceed the applicable Limit of Insurance of this policy. The most we will pay if this policy has higher limits than any Other Policy is the difference between the applicable Limit of Insurance of this policy and the limit of insurance for any such Other Policies.

**Schedule of Other Policies:**

| Country of Issuance | Insurer | Policy Number |
|---------------------|---------|---------------|
| Canada              | ACE INA Insurance | XBC324825 |

All other terms and conditions of this policy remain unchanged.
