RE: Environmental Covenant for the M-508 Disposal Site
ATK Launch Systems - Promontory Facility, EPA I.D. #UTD009081357

Dear Mr. Gosen:

The Division of Solid and Hazardous Waste has completed its review of the Environmental Covenant for the M-508 disposal site. I have signed the original document, which is enclosed
with this letter and is being returned to you so that ATK may now have it recorded by Box Elder County.

As stated in your letter dated March 4, 2008 and in Paragraph 16 of the covenant, please note that ATK shall provide a file and date-stamped copy of the recorded Environmental Covenant
to me. Thank you for your cooperation. If you have any questions, please contact Jeff Vandel at 538-6170.

Sincerely,
