        <footnote id="F2">The restricted stock units were accrued under the Lear Corporation Management Stock Purchase Plan pursuant to a deferred compensation election.  Generally, units settle approximately three years from the date of grant; however, a participant may elect to defer settlement of units beyond three years. Mr. Ninivaggi has not, as of the date of this filing, elected to defer settlement of his 2004 units beyond 2007.</footnote>
