Dear Frank:

We are very sorry for the delay in answering your letters on the captioned. In reference to your original letter of May 3rd, 1971 we propose cancelling our Endorsement #5 and substituting the following language "it is agreed that our Endorsement #2, as respects malpractice, shall not apply to medical malpractice as pertaining to doctors and nurses hired by the Insured for the purpose of treating employees of the Insured and on duty at various locations of the Insured."

In addition, you should be receiving shortly the correction to Endorsement #4 including the definition of Insured-IBM World Trade Corporation. Should you have any questions at all please feel free to call.

Sincerely,

Steven L. Reale  
Executive Underwriter
