Re: Standby Letter of Credit No. 216436002 Amendment No. 1
Alliant Techsystems Inc.

Dear Mr. Montalto:

The Division received your Amendment No.1, dated June 9, 2003, wherein you sought to reduce the amount of Letter of Credit No. 216436002. We have initiated a detailed assessment of
the permit cost estimates for closure and post-closure care associated with the Alliant Techsystem Inc. facility (ATK Thiokol Propulsion-Promontory) located in Utah to determine if the
reduction is appropriate. We have also contacted personnel at the Promontory facility to make them aware of our efforts.

Without the supporting justification, the Division cannot agree at this time with the decrease in funding by $488,322.00 as indicated in your Amendment No. 1 for the Letter of Credit
No. 216436002. Please be advised that we are rejecting and returning your Amendment No. 1. Until our review is complete and a decision is made regarding an acceptable monetary amount
for closure and post-closure, our records shall continue to show that the face value of said letter of credit is $6,212,844.00.

If you have any questions, please do not hesitate to contact Blake C. Robertson of my staff at [phone] or by email [e-mail].

Sincerely,
