        <footnote id="F3">Each stock unit is equal in value to one share of Lear Corporation common stock</footnote>
        <footnote id="F4">The deferred stock units were accrued under the Lear Corporation Outside Directors Compensation Plan pursuant to a deferral election and are generally to be paid out in cash upon the earliest of the date elected by Mr. Parrott, the date of Mr. Parrott's retirement as a director of Lear Corporation or the date of a change of control of Lear Corporation.  Mr. Parrott had elected to have all of his stock units be paid out on January 1, 2005, or in installments as soon as administratively possible following the completion of a six-month holding period.  The remainder of his deferred stock units will be paid out in the final such installment on or about May 2, 2005.</footnote>
