September 23, 2003, between Lear Corporation (the "Company") and the individual
whose name appears on the signature page hereof (the "Participant"), who is a

consecutive trading days preceding January 1, 2006 and (b) the dividends

<PAGE>

         4.    Performance Goals.

         a.    Relative Return to Shareholders:

               i.   Threshold: The Company is ranked above the 42nd percentile.

               ii.  Target: The Company is ranked above the 57th percentile.

               iii. Superior: The Company is ranked above the 85th percentile.

         b.    Return on Invested Capital:

               i.   Threshold: 3%* per year average

               ii.  Target:    5% per year average

               iii. Superior:  7% per year average

               *If threshold payout is not achieved by meeting the 3% compounded
               annual growth, an opportunity exists to earn threshold payout if
               the % change in ROIC when compared to the Peer Group is above the
               57th percentile.

         5.    Performance Shares.

         a.    The number of Performance Shares earned by a Participant with
respect to each performance measure during the Performance Period shall be
determined under the following chart:

<TABLE>
<CAPTION>
--------------------------------------------------------------------------------
                               Performance Shares
--------------------------------------------------------------------------------
Performance At    Relative Return to Shareholders     Return on Invested Capitol

<S>               <C>                                 <C>
Threshold                       1162                               1162
--------------------------------------------------------------------------------
Target                          2323                               2323
--------------------------------------------------------------------------------
Superior                        3485                               3485
--------------------------------------------------------------------------------
</TABLE>

         b.    In the event that the Company's actual performance does not meet
threshold for that performance measure, Performance Shares shall not be earned
with respect to that performance measure.

         c.    If the Company's actual performance for a performance measure is
between "threshold" and "target," the Performance Shares earned shall equal the
Performance Shares for threshold plus the number of Performance Shares
determined under the following formula:

         (TAS - TS)   x         AP - TP
                               --------
                               TAP - TP

         TAS =         The Performance Shares for target.

         TS =          The Performance Shares for threshold.

         AP =          The Company's actual performance.

         TP =          The threshold performance goal.

         TAP =         The target performance goal.

                                       2
<PAGE>

         d.    If the Company's actual performance for a performance measure is
between "target" and "superior," the Performance Shares earned shall equal the
Performance Shares for target plus the number of Performance Shares determined
under the following formula:

         (SS - TAS)   x        AP - TAP
                               --------
                               SP - TAP

         SS =          The Performance Shares for superior.

         TAS =         The Performance Shares for target.

         AP =          The Company's actual performance.

         TAP =         The target performance goal.

         SP =          The superior performance goal.

         e.    If the Company's actual performance for performance measure
exceeds "superior," the Performance Shares earned shall equal the Performance
Shares for superior.

         6.    Timing and Form of Payout. Except as hereinafter provided, after
the end of the Performance Period, the Participant shall be entitled to receive
a number of shares of the Company's common stock, par value $.01 per share
("Common Stock"), equal to his total number of Performance Shares determined
under Section 5. Delivery of such shares of Common Stock shall be made as soon
as administratively feasible after the Committee certifies the actual
performance of the Company during the Performance Period. Notwithstanding the
foregoing, any delivery of shares of Common Stock under this Section may be
deferred by the Participant with the Committee's consent; provided, that the
Participant's election to defer occurs prior to the expiration of the second
year of the Performance Period. Notwithstanding anything herein to the contrary,
the Committee may defer delivery of any shares of Common Stock to the
Participant under this Section if the delivery of such shares of Common Stock
would constitute compensation to the Participant that is not deductible by the
Company or an Affiliate due to the application of Code Section 162(m); provided,
that such shares of Common Stock deferred pursuant to this sentence shall be
delivered to the Participant on or before the January 15 of the first year in
which the Participant is no longer a "covered employee" of the Company (within
the meaning of Code Section 162(m) following the end of the Performance Period
or, if later, the deferred delivery date elected by the Participant in
accordance with the preceding sentence.

         7.    Termination of Employment Due to Death, Retirement, or
Disability. If a Participant ceases to be an employee prior to the end of the
Performance Period by reason of death, Retirement or Disability, the Participant
(or in the case of the Participant's death, the Participant's beneficiary) shall
be entitled to receive shares of Common Stock equal to the number of shares of
Common Stock the Participant would have been entitled to under Section 6 if he
or she had remained employed until the last day of the Performance Period
multiplied by a fraction, the numerator of which shall be the number of full
calendar months during the period of January 1, 2003 through the date of the
Participant's employment terminated and the denominator of which shall be
thirty-six. The delivery of such shares of Common Stock shall be made as soon as
administratively feasible after the end of the Performance Period, whether or
not the Participant had elected under Section 6 above to defer receipt of Common
Stock deliverable under this Award.

               Any distribution made with respect to a Participant who has died
shall be paid to the beneficiary designated by the Participant pursuant to
Article 11 of the Plan to receive the Participant's shares of Common Stock under
this Award. If the Participant's beneficiary predeceases the Participant or no

                                       3
<PAGE>

beneficiary has been designated, distribution of the Participant's shares of
Common Stock under this Award shall be made to the Participant's surviving
spouse and if none, to the Participant's estate.

         8.    Termination of Employment for Any Other Reason. Except as
provided in Section 7, the Participant must be an employee of the Company and/or
an Affiliate continuously from the date of this Award until the last day of the
Performance Period to be entitled to receive any shares of Common Stock with
respect to any Performance Shares he may have earned hereunder.

         9.    Assignment and Transfers. The rights and interests of the
Participant under this Award may not be assigned, encumbered or transferred
except, in the event of the death of the Participant, by will or the laws of
descent and distribution.

         10.   Withholding Tax. The Company and any Affiliate shall have the
right to retain shares of Common Stock that are distributable to the Participant
hereunder to the extent necessary to satisfy the minimum required withholding
taxes, whether federal or state, triggered by the distribution of shares of
Common Stock under this Award.

         11.   No Limitation on Rights of the Company. The grant of this Award
shall not in any way affect the right or power of the Company to make
adjustments, reclassification, or changes in its capital or business structure,
or to merge, consolidate, dissolve, liquidate, sell or transfer all or any part
of its business or assets.

         12.   Plan and Agreement Not a Contract of Employment. Neither the Plan
nor this Agreement is a contract of employment, and no terms of employment of
the Participant shall be affected in any way by the Plan, this Agreement or
related instruments except as specifically provided therein. Neither the
establishment of the Plan nor this Agreement shall be construed as conferring
any legal rights upon the Participant for a continuation of employment, nor
shall it interfere with the right of the Company or any Affiliate to discharge
the Participant and to treat him or her without regard to the effect that such
treatment might have upon him or her as a Participant.

         13.   Participant to Have No Rights as a Stockholder. The Participant
shall not have any rights as a stockholder with respect to any shares of Common
Stock subject to this Award prior to the date on which he or she is recorded as

               *If threshold payout is not achieved by meeting the 3% compounded
               annual growth, an opportunity exists to earn threshold payout if
               the % change in ROIC when compared to the Peer Group is above the
               57th percentile.

         5.    Performance Shares.

         a.    The number of Performance Shares earned by a Participant with

Threshold                        929                                929

--------------------------------------------------------------------------------
</TABLE>

         b.    In the event that the Company's actual performance does not meet
threshold for that performance measure, Performance Shares shall not be earned
with respect to that performance measure.

         c.    If the Company's actual performance for a performance measure is
between "threshold" and "target," the Performance Shares earned shall equal the
Performance Shares for threshold plus the number of Performance Shares
determined under the following formula:

         (TAS - TS)   x         AP - TP
                               --------
                               TAP - TP

                                       2
<PAGE>
         TAS =         The Performance Shares for target.

         TS =          The Performance Shares for threshold.

         AP =          The Company's actual performance.

         TP =          The threshold performance goal.

         TAP =         The target performance goal.

         d.    If the Company's actual performance for a performance measure is
between "target" and "superior," the Performance Shares earned shall equal the
Performance Shares for target plus the number of Performance Shares determined
under the following formula:

         (SS - TAS)   x        AP - TAP
                               --------
                               SP - TAP

         SS =          The Performance Shares for superior.

         TAS =         The Performance Shares for target.

         AP =          The Company's actual performance.

         TAP =         The target performance goal.

         SP =          The superior performance goal.

         e.    If the Company's actual performance for performance measure
exceeds "superior," the Performance Shares earned shall equal the Performance
Shares for superior.

         6.    Timing and Form of Payout. Except as hereinafter provided, after
the end of the Performance Period, the Participant shall be entitled to receive
a number of shares of the Company's common stock, par value $.01 per share
("Common Stock"), equal to his total number of Performance Shares determined
under Section 5. Delivery of such shares of Common Stock shall be made as soon
as administratively feasible after the Committee certifies the actual
performance of the Company during the Performance Period. Notwithstanding the
foregoing, any delivery of shares of Common Stock under this Section may be
deferred by the Participant with the Committee's consent; provided, that the
Participant's election to defer occurs prior to the expiration of the second
year of the Performance Period. Notwithstanding anything herein to the contrary,
the Committee may defer delivery of any shares of Common Stock to the
Participant under this Section if the delivery of such shares of Common Stock
would constitute compensation to the Participant that is not deductible by the
Company or an Affiliate due to the application of Code Section 162(m); provided,
that such shares of Common Stock deferred pursuant to this sentence shall be
delivered to the Participant on or before the January 15 of the first year in
which the Participant is no longer a "covered employee" of the Company (within
the meaning of Code Section 162(m) following the end of the Performance Period
or, if later, the deferred delivery date elected by the Participant in
accordance with the preceding sentence.

         7.    Termination of Employment Due to Death, Retirement, or
Disability. If a Participant ceases to be an employee prior to the end of the
Performance Period by reason of death, Retirement or Disability, the Participant
(or in the case of the Participant's death, the

                                       3
<PAGE>

Participant's beneficiary) shall be entitled to receive shares of Common Stock
equal to the number of shares of Common Stock the Participant would have been
entitled to under Section 6 if he or she had remained employed until the last
day of the Performance Period multiplied by a fraction, the numerator of which
shall be the number of full calendar months during the period of January 1, 2003
through the date of the Participant's employment terminated and the denominator
of which shall be thirty-six. The delivery of such shares of Common Stock shall
be made as soon as administratively feasible after the end of the Performance
Period, whether or not the Participant had elected under Section 6 above to
defer receipt of Common Stock deliverable under this Award.

         Any distribution made with respect to a Participant who has died shall
be paid to the beneficiary designated by the Participant pursuant to Article 11
of the Plan to receive the Participant's shares of Common Stock under this
Award. If the Participant's beneficiary predeceases the Participant or no
beneficiary has been designated, distribution of the Participant's shares of
Common Stock under this Award shall be made to the Participant's surviving
spouse and if none, to the Participant's estate.

         8.    Termination of Employment for Any Other Reason. Except as
provided in Section 7, the Participant must be an employee of the Company and/or
an Affiliate continuously from the date of this Award until the last day of the
Performance Period to be entitled to receive any shares of Common Stock with
respect to any Performance Shares he may have earned hereunder.

         9.    Assignment and Transfers. The rights and interests of the
Participant under this Award may not be assigned, encumbered or transferred
except, in the event of the death of the Participant, by will or the laws of
descent and distribution.

         10.   Withholding Tax. The Company and any Affiliate shall have the
right to retain shares of Common Stock that are distributable to the Participant
hereunder to the extent necessary to satisfy the minimum required withholding
taxes, whether federal or state, triggered by the distribution of shares of
Common Stock under this Award.

         11.   No Limitation on Rights of the Company. The grant of this Award
shall not in any way affect the right or power of the Company to make
adjustments, reclassification, or changes in its capital or business structure,
or to merge, consolidate, dissolve, liquidate, sell or transfer all or any part
of its business or assets.

         12.   Plan and Agreement Not a Contract of Employment. Neither the Plan
nor this Agreement is a contract of employment, and no terms of employment of
the Participant shall be affected in any way by the Plan, this Agreement or
related instruments except as specifically provided therein. Neither the
establishment of the Plan nor this Agreement shall be construed as conferring
any legal rights upon the Participant for a continuation of employment, nor
shall it interfere with the right of the Company or any Affiliate to discharge
the Participant and to treat him or her without regard to the effect that such
treatment might have upon him or her as a Participant.

         13.   Participant to Have No Rights as a Stockholder. The Participant
shall not have any rights as a stockholder with respect to any shares of Common
Stock subject to this Award prior to the date on which he or she is recorded as
the holder of such shares of Common Stock on the records of the Company.
