Dear Mr. Parent:

This will confirm the understanding and agreement between the Company and the Union concerning Advanced Refurbishment Operations (ARO).

It is understood and agreed that the seniority date of those employees who were Howmet employees at the time of the acquisition of ARO will be September 10, 1997.  Their Howmet seniority date will serve to differentiate between employees where seniority is a factor.

Sincerely,

James R. Miller

Vice President, Industrial Relations

Accepted this 6th day of December 2004
