Dear Pat:

As a follow up to my January 23, 1992 letter regarding the captioned policy, enclosed is an endorsement amending the Schedule of Underlying Insurance. We requested this revision as the Schedule indicated a Limit of Liability of $10,000,000 part of $60,000,000 each Occurrence/Aggregate. The Schedule now correctly reflects the limit of this layer as $55,000,000 each Occurrence/Aggregate excess of underlying insurance.

Please attach this endorsement to your copy of the policy.

Very truly yours,

**Stephen B. Luongo**
Assistant Vice President
