B. Any liability, including, but not limited to settlements, judgments, costs, charges, expenses, costs of investigations, or the fees of attorneys, experts, or consultants arising

1. directly or individually out of the actual, alleged or threatened existence, discharge, seepage, migration, disposal, release or escape of "pollutants".

2. a. from any request, demand or order that any insured or others test for, monitor, clean-up, remove, contain, treat, detoxify or neutralize, or in any way respond to, or assess the effects of "pollutants"; or

b. from any claim or suit by or on behalf of a governmental authority for damages because of testing for, monitoring, cleaning up, removing, containing, treating, detoxifying or neutralizing, or in any way responding to, or assessing the effects of "pollutants".

As used in this endorsement "pollutants" means any man-made or naturally occurring, solid, liquid, gaseous or thermal irritant or contaminant, including, but not limited to smoke, vapor, soot, fumes, acid, alkalis, chemicals, and waste. Waste includes materials to be recycled, reconditioned or reclaimed.

However, it is agreed that this exclusion does not apply to any liability, damage, loss or expense as described herein for which coverage is afforded under NATIONAL UNION FIRE INSURANCE COMPANY OF PITTSBURGH, PA., Policy Number 5443148, and then for no broader coverage than is afforded by such insurance (hereafter referred to as the "Underlying Pollution Coverage"). In the event that "Underlying Pollution Coverage" is amended or deleted after the inception date of this policy, we must be so advised within 14 days after the effective date of such amendment or deletion.

Any amendment which deletes in part or in whole the "Underlying Pollution Coverage" shall in like manner delete the coverage provided by this endorsement.

Any amendment which broadens coverage under the "Underlying Pollution Coverage" shall not be binding upon us unless our agreement is acknowledged in writing by an authorized representative of the Company.
