This new endorsement (which replaces existing endorsement CG 21 16 -- Exclusion - Designated Professional Services) clarifies that liability arising out of the following services is excluded:

- Medical or diagnostic testing, techniques or procedures used for the detection, diagnosis and treatment of any sickness, disease, condition or injury or the evaluation of a patient's response to treatment; or
- The reporting of or reliance upon the results of such medical or diagnostic testing, techniques or procedures.

**CG 22 33 -- Exclusion - Testing or Consulting Errors and Omissions**

This revised endorsement adds new paragraph 3, which excludes liability arising out of an error, omission, defect or deficiency in experimental data or the insured's interpretation of that data.

**CG 22 74 -- Amendment Of Contractual Liability Exclusion For Personal Injury Limited To False Arrest, Detention Or Imprisonment For Designated Contracts Or Agreements**

In order to clarify that:

Endorsement CG 24 10 will now apply to the Products/Completed Operations Liability Coverage Part only.

This endorsement has been revised to specifically set forth which Aggregate Limit will apply with respect to a given occurrence or accident.
