                                SECOND AMENDMENT
                                     TO THE
                   LKQ CORPORATION EMPLOYEES' RETIREMENT PLAN

     WHEREAS, LKQ Corporation (the "Company") maintains the LKQ Corporation
Employees' Retirement Plan (the "Plan"); and

     WHEREAS, amendment of the Plan is deemed desirable to reflect certain
provisions of the Economic Growth and Tax Relief Reconciliation Act of 2001
("EGTRRA") and certain other distribution changes under IRS regulations and is
intended as good faith compliance with the requirements of EGTRRA and is to be
construed in accordance with EGTRRA and guidance issued thereunder; and

     WHEREAS, except as otherwise provided in a particular of the amendment,
such amendment shall be effective as of the first day of the first Plan Year
beginning after December 31, 2001;

     NOW, THEREFORE, by virtue and in exercise of the power reserved to the
company under Section 11.1 of the Plan, and pursuant to the authority delegated
to the undersigned officers of the company by resolutions of the Compensation
Committee of its Board of Directors, the Plan be and hereby is amended in the
following particulars:

1.   By substituting for paragraph (c) of the definition of "Compensation" in
     Section 2.1 of the Plan the following:

"(c) ANNUAL LIMIT ON COMPENSATION. An Employee's Compensation for any Plan Year
shall not exceed $200,000, as adjusted pursuant to Section 401(a)(17) of the
Code. For purposes of computing the Pre-Tax Contributions withheld from a
Participant whose Compensation exceeds such limit, all Compensation paid to the
Participant during the period during which he has elected to have Pre-Tax
Contributions withheld shall be taken into account until the total Compensation
taken into account equals such limit."

<Page>

2.   By substituting for the definition of "Key Employee" in Section 2.1 of the
     Plan the following:

"(a) GENERAL RULE. Except as otherwise provided in this Section, an Employee
shall be considered a Key Employee for any Plan Year if, at any time during the
Plan Year which contains the Top-Heavy Determination Date, he:

     (i)    is an officer of any Employer or Affiliate whose Modified 415
            Compensation exceeds $130,000; or

     (ii)   owns more than five percent of the stock of an Employer or
            Affiliate; or

     (iii)  owns more than one percent of the stock of an Employer or Affiliate
            and receives Modified 415 Compensation for any Plan Year in which he
            owns such percentage in excess of $150,000 (determined in accordance
            with Section 416(i)(1)(B) of the Code).

(b)  PURPOSE. The purpose of this Section is to conform to the definition of
"key employee" set forth in Section 416(i)(1) of the Code effective as of
January 1, 2002 and thereafter, which is incorporated herein by reference, and
to the extent that this Section shall be inconsistent with Section 416(i)(1) of
the Code, either by excluding Employees who would be classified as "key
employees" thereunder or by including Employees who would not be so classified,
the provisions of Section 416(i)(1) of the Code shall govern and control."

3.   By substituting for paragraphs (e) and (f) of the definition of "Top-Heavy
     Year" in Section 2.1 of the Plan the following:

"(e) ACCOUNT BALANCES. For purposes of this Section, account balances shall
include (i) all Contributions which any Employer or Affiliate has paid or is
legally obligated to pay to any employee plan as of the Top-Heavy Determination
Date (including Contributions made thereafter if they are allocated as of the
Top-Heavy Determination Date) and all Forfeitures allocated as of the Top-Heavy
Determination Date, and (ii) all distributions made to a Participant or his
Beneficiary during the 1-year period ending on the Top-Heavy Determination Date
(5-year period ending on the Top-Heavy Determination Date for Plan Years
beginning prior to January 1, 2002) (or, in the case of a defined benefit plan,
the actuarial present value as of the Top-Heavy Determination Date of such
distributions). Effective for Plan Years beginning after December 31, 2001, in
the case of a distribution made for a reason other than separation from service,
death or disability, this provision shall be applied by substituting "5-year
period" for "1-year period." If any plan that was terminated within the 1-year
period ending on the Top-Heavy Determination Date (5-year period ending on the
Top-Heavy Determination Date for Plan Years beginning prior to January 1, 2002)
would, if it had not been terminated, be a plan described in paragraph (b),
distributions made under such plan shall also be taken into account. For
purposes of this Section, account balances shall also include amounts which are
attributable to Contributions made by the Participants (other than deductible
voluntary contributions under Section 219 of the Code) but shall not include any
rollover (as defined in Section 402 of the Code) or a direct transfer from the
trust of any employee plan qualified under Section 401(a) of the Code if such
plan is not maintained by an Employer or

<Page>

Affiliate and such rollover or transfer is made at the request of the
Participant after December 31, 1983.

(f)  CERTAIN FORMER EMPLOYEES. Anything to the contrary notwithstanding, if an
Employee has not performed any services for any Employer or Affiliate at any
time during the 1-year period ending on the Top-Heavy Determination Date (or
prior to January 1, 2002, within the 5-year period ending on the Top-Heavy
Determination Date), his account balance (in the case of a defined contribution
plan) or his accrued benefit (in the case of a defined benefit plan) shall not
be taken into consideration in the determination of whether the Plan Year is a
Top-Heavy Year."

4.   By substituting for Section 5.4 of the Plan the following:

"5.4 ROLLOVER CONTRIBUTIONS. An Eligible Employee may make a Contribution to the
Plan which constitutes a rollover of benefits from another plan qualified under
Section 401(a) of the Code (either directly or through an IRA described in
Section 408(d)(3)(A)(ii) of the Code, to the extent permissible under applicable
law), Section 403(a) of the Code, Section 403(b) of the Code, and Section 457 of
the Code, or cause the trustee of another plan to make a direct transfer of such
benefits on his behalf (in any case, a "Rollover Contribution"). In no event
shall such Contribution consist of after-tax employee contributions. All
Rollover Contributions shall be allocated to a separate Rollover Account
maintained for the Participant. The Administrator may establish uniform rules
limiting or restricting Rollover Contributions."

5.   By substituting for Section 6.1 of the Plan the following:

"6.1 LIMIT ON ANNUAL ADDITIONS.

     (a)    LIMITATION. Notwithstanding any other provisions of the Plan, the
     amount of annual additions (as hereinafter defined) allocated to a
     Participant's Account for any Limitation Year shall not exceed an amount
     equal to the lesser of:

            (i)   $40,000 (as adjusted pursuant to Section 415(d) of the Code as
                  of the first day of such Limitation Year); or

            (ii)  100 percent of the Participant's 415 Compensation for the
                  Limitation Year, increased by amounts treated as annual
                  additions solely by reason of subparagraph (b)(iv);

reduced in either case by the amount of annual additions credited to the
Participant's account for the limitation Year under any other defined
contribution plan maintained by an Employer or 415 Affiliate. For purposes of
applying this Section to contributions made following a period of Qualified
Military Service pursuant to Section 5.7, a Participant's 415 Compensation shall
include the amount of 415 Compensation he would have received had he been
employed during such period of Qualified Military Service, based on his rate of
pay that would have been in effect during such period or, if such rate of pay is
not reasonably certain, his average compensation during the 12 month period of
employment (or the total period of employment if less) immediately preceding the
Qualified Military Service. "

<Page>

6.   By deleting paragraphs (d), (e), (f) and (g) of Section 6.1 of the Plan and
     by substituting for paragraphs (d) and (e) the following:

"(d) AGGREGATION OF PLANS. For purposes of this Section 6.1, all defined benefit
plans of any Employer or 415 Affiliate, whether or not terminated, are to be
treated as one defined benefit plan, and all defined contribution plans of any
Employer or 415 Affiliate, whether or not terminated, are to be treated as one
defined contribution plan.

(e)  PARTICIPATION IN DEFINED BENEFIT PLAN. Anything to the contrary
notwithstanding, if during any Limitation Year a Participant also participates
in a defined benefit plan (as defined in Section 414(j) of the Code) maintained
by an Employer or 415 Affiliate, the annual additions under this Plan and the
projected annual benefit under the defined benefit plan shall be separately
determined pursuant to the rules in effect for such plan."

7.   By substituting for Section 6.2(a) of the Plan the following:

"(a) LIMITATION. The total amount of Pre-Tax Contributions made on behalf of any
Participant under this Plan, plus the total amount of before-tax elective
deferrals made on behalf of the Participant under any other plan described in
401(k) or 402(h)(1)(B) of the Code plus amounts used to purchase an annuity
under 403(b) of the Code pursuant to a salary reduction agreement under
402(g)(3) of the Code, in any calendar year shall not exceed $11,000 (or such
larger dollar limitation as may then be applicable for such calendar year under
402(g) of the Code)."

8.   By substituting for Section 6.3 of the Plan the following:

"6.3 ACTUAL DEFERRAL PERCENTAGE LIMITATION.

     (a)    LIMITATION. The Pre-Tax Contributions of Participants who are
     Highly-Compensated Employees shall be further limited for each Plan Year so
     that the Highly Compensated ADP does not exceed the Maximum ADP. The
     Administrator may reduce the Pre-Tax Deferral Elections of such
     Participants in accordance with paragraph (c) during the Plan Year to
     prevent this limitation from being exceeded, but in no event shall the
     Administrator have any liability to any Highly Compensated Employee if it
     does not do so.

     (b)    CORRECTION OF EXCESS CONTRIBUTIONS. If the limitation of paragraph
     (a) is exceeded for any Plan Year after taking into account any Qualified
     Non-Elective Contributions, the excess Pre-Tax Contribution (as determined
     under paragraph (c)) of each Participant who is a Highly-Compensated
     Employee shall be recharacterized as an After-Tax Contribution to the
     extent the Participant so elects and to the extent such recharacterization
     does not cause the limitation of Section 6.4 to be exceeded, and otherwise
     distributed to such Participant.

All distributions shall be made, notwithstanding any other restriction on
distributions in the Plan, not later than 2 1/2 months following the end of the
Plan Year if possible, and in any event not later than the last day of the
following Plan Year. All recharacterizations shall be made not later than 2 1/2
months following the end of the Plan Year. The amount required to be distributed
or recharacterized under this Section 6.3 shall be reduced by

<Page>

any amount previously distributed to satisfy Section 6.2. Any amount distributed
or recharacterized shall include the share of income allocable to such
distribution, determined in accordance with the method used under Section 6.2(e)
or 6.2(f), and all references to excess Pre-Tax Contributions shall be deemed to
include such allocated income

     (c)    DETERMINATION OF EXCESS CONTRIBUTIONS. If it is necessary to
     determine the excess Pre-Tax Contributions of Highly Compensated Employees
     pursuant to paragraph (b) for any Plan Year, the following method shall be
     used:

             (i)  First, Contributions of the Highly Compensated Employee or
                  Employees whose Deferral Percentage is the highest must be
                  reduced until their Deferral Percentage is equal to the
                  greater of the Deferral Percentage which will cause the Highly
                  Compensated ADP not to exceed the Maximum ADP or the Deferral
                  Percentage of the Highly Compensated Employee or Employees who
                  have the second highest Deferral Percentage. The same
                  procedure shall then be applied, if necessary, to the Pre-Tax
                  Contributions of the Highly Compensated Employees who have the
                  second highest Deferral Percentage (including those whose
                  Deferral Percentage was reduced in the prior step), and so on
                  until the Highly Compensated ADP no longer exceeds the Maximum
                  ADP. The aggregate amount by which all Pre-Tax Contributions
                  would have to be reduced, using this method, so that the
                  Highly Compensated ADP would no longer exceed the Maximum ADP
                  is hereinafter referred to as the "Aggregate Excess
                  Contribution."

             (ii) Second, the Administrator shall determine the amount by which
                  the Pre-Tax Contributions (determined without regard to
                  subparagraph (c)(i) above) of the Highly Compensated Employee
                  or Employees whose Pre-Tax Contributions are the largest in
                  dollar amounts must be reduced until either the total amount
                  of reductions equals the Aggregate Excess Contribution or
                  their Pre-Tax Contributions are equal in amount to the Pre-Tax
                  Contributions of the Highly Compensated Employee or Employees
                  who have the second largest amount of Pre-Tax Contributions.
                  The same procedure shall then be applied, if necessary, to the
                  Pre-Tax Contributions of the Highly Compensated Employees who
                  received the second largest dollar amount of Pre-Tax
                  Contributions (including those whose Pre-Tax Contributions
                  were reduced in the prior step), and so on until the total
                  amount of reductions equals the Aggregate Excess Contribution.

            (d)   CALCULATION OF ADP. In calculating the ADP for the purpose of
     this Section 6.3, the Highly-Compensated Employee ADP will be determined by
     treating all cash or deferred arrangements maintained by an Employer or an
     Affiliate under which the Highly-Compensated Employee is eligible (other
     than those that may not be permissively aggregated) as a single aggregated
     plan. For the purpose of determining whether such an aggregated plan
     satisfies the actual

<Page>

     deferral percentage test of Section 6.3(a), all Employee Contributions or
     other elective contributions that are made under two or more plans
     maintained by an Employer or an Affiliate that are so aggregated for the
     purposes of Code Section 401(a)(4) or Section 410(b) (other than Code
     Section 410(b)(2)(A)(ii)) will be treated as made under a single aggregated
     plan. If two or more plans maintained by an Employer or an Affiliate are
     permissively aggregated for the purpose of Code Section 401(k), the
     aggregated plans must also satisfy Code Section 401(a)(4) and Section
     410(b) as though they were a single aggregated plan.

            (e)   FORFEITURE OF MATCHING CONTRIBUTIONS. The portion of any
     Matching Contributions that relates to any excess Pre-Tax Contributions
     distributed pursuant to this Section 6.3 shall be forfeited,
     notwithstanding any other provision of the Plan or the Participant's
     Vesting Service."

9.   By substituting for Section 6.4 of the Plan the following:

"6.4 ACTUAL CONTRIBUTION PERCENTAGE LIMITATION.

     (a)    LIMITATION. The Matching Contributions of Participants who are
Highly Compensated Employees shall be further limited for each Plan Year so that
the Highly Compensated ACP does not exceed the Maximum ACP (or such lower amount
as is determined under paragraph (e)). The Administrator may reduce the amount
of Matching Contributions allocated such Participants in accordance with
paragraph (d) during the Plan Year to prevent this limitation from being
exceeded, but in no event shall the Administrator have any liability to any
Highly Compensated Employee if it does not do so.

     (b)    CORRECTION OF EXCESS CONTRIBUTIONS. If the limitation of paragraph
(a) is exceeded for any Plan Year after taking into account any Qualified
Non-Elective Contributions and the recharacterization of Pre-Tax Contributions
pursuant to paragraph (c), the excess Matching Contribution (as determined under
paragraph (d) of each Participant who is a Highly-Compensated Employee shall be
distributed to such Participant. All distributions shall be made,
notwithstanding any other restriction on distributions in the Plan, not later
than 2 1/2 months following the end of the Plan Year if possible, and in any
event not later than the last day of the following Plan Year. Each such
distribution shall include the share of income allocable to such distribution,
determined in accordance with the method used under Section 6.2(e) or 6.2(f),
and all references to excess Contributions shall be deemed to include such
allocated income.

     (c)    USE OF PRE-TAX CONTRIBUTIONS. For purposes of this Section, a
portion of the Pre-Tax Contributions made on behalf of Participants who are
Non-Highly Compensated Employees shall be treated as Matching Contributions.
Such amount shall be determined by applying the method set forth in paragraph
(d) to recharacterize the Pre-Tax Contributions of Non-Highly Compensated
Employees as Matching Contributions until either the limitation of paragraph (a)
is satisfied or any further recharacterization would cause the limitation of
Section 6.3 to be exceeded. If before-tax contributions under any other plan
maintained by an Employer or Affiliate are included in a Non-Highly Compensated
Employee's Contribution Percentage, such before-tax contributions may be
recharacterized only if such other plan and the Plan would satisfy Section
410(b) of the

<Page>

Code (without reliance on the average benefits test) if treated as a single
plan. Pre-Tax Contributions that are so recharacterized shall continue to be
treated as Pre-Tax Contributions for all other purposes under the Plan,
including specifically limitations on Forfeitures and distributions.

     (d)    DETERMINATION OF EXCESS CONTRIBUTIONS. If it is necessary to
determine the excess Matching Contributions of Highly Compensated Employees
pursuant to paragraph (b) for any Plan Year, the same two-step method described
in Section 6.3(c) shall be used.

     (e)    FORFEITURE OF NONVESTED CONTRIBUTIONS. If a distribution of an
excess Matching Contribution must be made to a Participant under this Section
6.4 at a time when the Participant is not fully Vested in his Matching
Contribution Account, then the amount distributed to such Participant shall be
equal to the amount of the excess Matching Contribution multiplied by the
percentage of the Matching Contribution Account that is Vested, and the
remaining portion of the excess Matching Contribution shall be forfeited.

     (f)    CALCULATION OF ACP. In calculating ACP for the purpose of this
Section 6.4, the Actual Contribution Percentage of a Highly-Compensated Employee
will be determined by treating all plans subject to Code Section 401(m)
maintained by an Employer or an Affiliate under which the Highly-Compensated
Employee is eligible (other than those that may not be permissively aggregated)
as a single aggregated plan. For the purpose of determining whether such an
aggregated plan satisfies the ACP test of section 6.4(a), all Employee
Contributions or other elective contribution s and Matching Contributions that
are made under two or more plans maintained by an Employer or an Affiliate that
are so aggregated for the purposes of Code Section 401(a)(4) or Section 410(b)
(other than Code Section 410(b)(2)(A)(ii)) will be treated as made under a
single aggregated plan. If two or more plans maintained by an Employer or an
Affiliate are permissively aggregated for the purpose of Code Section 401(m),
the aggregated plans must also satisfy Code Section 401(a)(4) and Section 410(b)
as though they were a single aggregated plan."

10.  By substituting the following for Section 6.5 of the Plan:

"6.5 LIMIT ON DEDUCTIBLE CONTRIBUTIONS Anything else contained herein to the
contrary notwithstanding, the total Contributions made by any Employer to the
Plan for any Plan Year (excluding After-Tax Contributions withheld by the
Employer) shall not exceed 25 percent of the aggregate Compensation paid by the
Employer to all Participants during the Plan Year, or such other amount as may
be deductible under Section 404 of the Code for such Plan Year (determined
without regard to Section 263A of the Code)."

11.  By substituting for Section 9.1(b) of the Plan the following:

"(b) SMALL ACCOUNT BALANCE. Effective for all distributions made after December
31, 2001, if the Participant's total Vested Account Balance at the time of
distribution, or the portion thereof distributed to a Beneficiary, does not
exceed $5,000.00, then distribution shall be made in the form described in
paragraph (a). For purposes of this Section 9.1(b), the determination of whether
a Participant's Vested Account Balance exceeds $5,000

<Page>

shall be made without regard to the portion of the Participant's Vested Account
Balance attributable to Rollover Contributions."

12.  By substituting the following for Section 9.2(a) of the Plan:

"(a) SMALL ACCOUNT BALANCES. If, at the time of a Participant's Termination of
Employment, his Vested Account Balance does not exceed the amount provided in
Section 9.1(b), the entire amount of the Vested Account Balance shall be
distributed to such Participant under Section 9.1(a) as soon as administratively
feasible.

     (i)    For purposes of this Section 9.2(a), the determination of whether a
            Participant's Account Balance exceeds the amount provided in Section
            9.1(b) upon his Termination of Employment shall be made without
            regard to whether the Participant's Account Balance exceeded such
            amount at a time prior to the Participant's Termination of
            Employment, and without regard to the portion of the Participant's
            Account Balance attributable to Rollover Contributions.

     (ii)   If, upon a Participant's Termination of Employment, his Account
            Balance (i) exceeds $1,000 but is less than the amount provided in
            Section 9.1(b), and (ii) the Participant fails to affirmatively
            elect to have his entire Account Balance distributed in accordance
            with Section 9.1(a), the Administrator shall transfer the
            Participant's Account Balance to an individual retirement account or
            a trustee or issuer designated by the Administrator, in its sole
            discretion, and shall notify the Participant, in writing, that the
            Participant's distribution may be transferred, without cost or
            penalty to the Participant, to another individual retirement account
            selected by the Participant. This Section 9.2(a)(ii) shall not
            become effective until the first date prescribed by the IRS and
            Department of Labor."

13.  By substituting for Section 9.3(b) of the Plan the following:

"(b)   DEATH OF PARTICIPANT AFTER DISTRIBUTION HAS COMMENCED. If a Participant
dies after distribution of his benefit has commenced and after the date
specified in Section 9.2(d)(ii), then distribution shall be made in accordance
with paragraph (c) unless distribution has been made by purchase of an annuity."

14.  By substituting for Section 9.5 of the Plan the following:

"9.5 DIRECT TRANSFERS. Any Participant, surviving spouse, or Alternate Payee
(but only with respect to an Alternate Payee who is the spouse or former spouse
of a Participant) who is entitled to receive an "eligible rollover
distribution," as hereinafter defined, shall have the right to direct the
transfer of all or a portion of such distribution directly to an individual
retirement account or annuity qualified under Section 408 of the Code (other
than an endowment contract) (an "IRA"), a defined contribution pension or
profit-sharing trust qualified under Section 401(a), an annuity plan qualified
under Section 403(a) of the Code, an annuity contract described in section
403(b) of the Code, an eligible plan under section 457 of the

<Page>

Code; or another "eligible retirement plan" as defined in Section 401(a)(31) of
the Code, which will accept such a transfer, provided that the amount so
transferred must either be the entire amount of such distribution or must be at
least $500. The Administrator shall furnish each Participant, Alternate Payee or
surviving spouse to whom this Section 9.5 applies with a notice describing his
right to a direct transfer and the tax consequences of a distribution. Such
notice shall be furnished not more than 90 days nor less than 30 days before the
Participant, Alternate Payee or surviving spouse is entitled to receive such
distribution, and no distribution shall be made until 30 days after he or she
has received such notice unless he or she waives such 30 day period in writing.
For purposes of this Section 9.5, an "eligible rollover distribution" means any
distribution that is at least $200.00, other than (i) a distribution that is
part of a series of substantially equal installment payments, paid not less
frequently than annually, over the life or life expectancy of the Participant,
the joint lives or joint life expectancies of the Participant and his
beneficiary, or a fixed period of 10 years or more, but only to the extent such
distribution exceeds the minimum amount required to be distributed under the
Plan, and (ii) a distribution of Pre-Tax Contributions made on account of
hardship. The Administrator may adopt administrative procedures to implement
direct transfers, which may vary the time periods and minimum amounts set forth
above, to the extent consistent with final Treasury Regulations issued under
Section 401(a)(31) of the Code."

15.  By adding the following sentences at the end of Section 10.4 of the Plan.

"Benefit under the Plan will be paid only if the Administrator decides in its
discretion that the applicant is entitled to such benefits."

            IN WITNESS WHEREOF, the Company has caused this amendment to be
executed by its duly authorized officers, this 31 day of December, 2002.
