purchase Shares from a Transferring Stockholder pursuant to Section 3.

of disposition.

     2.   RESTRICTIONS ON TRANSFER. Each Stockholder agrees that it will not
Transfer any interest in any or all of its Shares, except as expressly permitted
by this Agreement. No Transfer or purported Transfer of Shares in contravention
of this Agreement shall be effective for any purpose or confer upon any
transferee or purported transferee any rights whatsoever. Notwithstanding the
foregoing, a Transfer shall not be prohibited or restricted and shall not
require compliance with Section 3 or 4 of this Agreement if made to a Member of
the Immediate Family of such Stockholder or, if such Stockholder is not a
natural person, then to an Affiliate of such Stockholder (each such person being
herein called a "Permitted Transferee"); provided, however, that in the event of
any such Transfer, the Permitted Transferee shall take such transferred Shares
subject to the provisions of this Agreement.

                                        2
<Page>

     3.   RIGHT OF FIRST REFUSAL.

     (a)  In the event that a Stockholder (a "Transferring Stockholder")
proposes to Transfer any Shares pursuant to a bona fide offer from a third party
which is not an Affiliate of the Transferring Stockholder, the Transferring
Stockholder shall give the Company written notice of the price, terms and
conditions of the proposed sale. The Company shall have ten days from the date
of receipt of any such notice to agree to purchase up to all of such securities,
for the price and upon the terms and conditions specified in the notice, by
giving written notice to the Transferring Stockholder stating therein the
quantity of securities to be purchased up to all of such securities.

     (b)  In the event that the Company determines not to purchase all of the
Shares that the Transferring Stockholder proposes to transfer within the ten day
period specified in subsection (a), the Transferring Stockholder shall then give
each other Stockholder written notice of the price, terms and conditions of the
proposed sale (which shall be the same price, terms and conditions specified in
the notice to the Company pursuant to subsection (a)). Each such other
Stockholder shall have ten days from the date of receipt of any such notice to
agree to purchase up to the Stockholder's Pro Rata Share of such securities, for
the price and upon the terms and conditions specified in the notice, by giving
written notice to the Transferring Stockholder stating therein the quantity of
securities to be purchased up to such Stockholder's Pro Rata Share. If a
Stockholder desires to purchase more than such Stockholder's Pro Rata Share, the
Stockholder's notice shall so indicate. If less than all of the Shares that the
Transferring Stockholder proposes to Transfer (other than Shares the Company
agreed to purchase) have been subscribed for by the Electing Purchasers, the
remaining available Shares shall be allocated among any over-subscribing
Electing Purchasers pro rata according to the number of Shares then held by each
such over-subscribing Electing Purchaser divided by the sum of the total number
of Shares then held by all over-subscribing Electing Purchasers.

     (c)  Subject to the provisions of Section 4, in the event the Stockholders
fail to exercise their right of first refusal with respect to all of the Shares
within the time period specified in subsection (b), the Transferring Stockholder
shall have 60 days thereafter to sell the Shares not elected to be purchased at
a price and upon terms and conditions no more favorable to the purchasers of
such securities than specified in the notice to the Company pursuant to
subsection (a). In the event the Transferring Stockholder has not sold such
Shares within the 60 day period, the Transferring Stockholder shall not
thereafter sell any of its Shares without first complying again with this
Section 3.

     4.   CO-SALE RIGHTS.

     (a)  A Stockholder shall not Transfer any of its Shares (other than Shares
which have been elected to be purchased by the Company or the other Stockholders
pursuant to Section 3) until each of the other Stockholders shall have been
given the opportunity, exercisable within ten days from the date of the notice
to them as specified in Section 3, to sell to the proposed transferee or
transferees, upon the same terms and conditions offered to the Transferring
Stockholder, its Co-Sale Pro Rata Share of the shares proposed to be sold. The
Stockholders participating in any such sale shall each pay a pro rata share of
the reasonable expenses incurred by the Transferring Stockholder in connection
therewith. To the extent one or more of the other Stockholders exercise such
right of participation in accordance with the terms and conditions set forth
below, the number of shares of Common Stock which the Transferring Stockholder
may sell pursuant to Section 3 shall be

                                        3
<Page>

correspondingly reduced. Stockholders who fail to notify the Transferring
Stockholder within ten days after the notice given pursuant to Section 3 shall
be deemed to have waived their rights under this Section 4. Any Transfer made
pursuant to this Section 4 shall be consummated within 60 days of the date of
the notice given pursuant to Section 3 and shall be conditioned upon the
agreement of the Transferring Stockholder or proposed transferee or transferees
that such Transferring Stockholder or proposed transferee or transferees will
purchase each Stockholder's Co-Sale Pro Rata Share of the Shares proposed to be
sold. The right of participation of each of the Stockholders (other than the
Transferring Stockholder) shall be subject to delivery by a participating
Stockholder to the Transferring Stockholder of one or more certificates,
properly endorsed for transfer, which represent the number of Shares which the
Stockholder elects to sell pursuant to this Section 4.

     (b)  The stock certificates which the other Stockholders deliver to the
Transferring Stockholder pursuant to subsection (a) shall be transferred by the
Transferring Stockholder to the proposed transferee or transferees in
consummation of the sale of the Shares pursuant to the terms and conditions
specified in the Section 3 notice to the Stockholders, and the Transferring
Stockholder shall promptly thereafter remit to each Stockholder that portion of
the sale proceeds to which the Stockholder is entitled by reason of its
participation in such sale.

     (c)  The exercise or nonexercise of the rights of the Stockholders
hereunder to participate in one or more sales of Shares made by a Transferring
Stockholder shall not adversely affect their rights to participate in subsequent
sales of Shares by a Transferring Stockholder.

     5.   EXCEPTIONS. The restrictions set forth in Sections 3 and 4 shall not
pertain or apply to (i) with respect to Section 4 only, ten percent of the
Shares held by the Transferring Stockholder as of the date of such Stockholder's
execution of this Agreement, (ii) any pledge of Common Stock made by the
Transferring Stockholder which creates a mere security interest, provided the
pledgee shall furnish the Company with a written agreement to be bound by and
comply with all provisions of this Agreement applicable to the Transferring
Stockholder, (iii) any transfer in connection with a merger, consolidation,
reorganization or any other similar corporate transaction involving the Company,
which transaction is approved by the Board of Directors of the Company, and (iv)
any transfer in connection with an underwritten public offering of the Common
Stock registered under the Securities Act of 1933.

     6.   PRE-EMPTIVE RIGHTS.

     (a)  The Company hereby grants to each of the Stockholders the right of
first refusal to purchase such Stockholder's Pre-Emptive Pro-Rata Share of any
New Securities that the Company may, from time to time, propose to sell and
issue. In the event that the Company proposes to undertake an issuance of New
Securities, it shall give each Stockholder written notice of its intention,
describing the type of New Securities, the price and the general terms upon
which the Company proposes to issue the same. Each Stockholder shall have 15
days from the effective date of any such notice to agree to purchase up to its
Pre-Emptive Pro Rata Share of such New Securities for the price and upon the
general terms specified in the notice by delivering written notice to the
Company and stating therein the quantity of New Securities to be purchased. If a
Stockholder desires to purchase more than its Pre-Emptive Pro Rata Share of such
New Securities, it shall so indicate in the notice. If less than all of the New
Securities are subscribed for by the Stockholders,

                                        4
<Page>

the remaining available New Securities shall be allocated among any
over-subscribing Stockholders pro rata according to the number of Shares then
held by each such Stockholder divided by the sum of the total number of Shares
then held by all over-subscribing Stockholders.

     (b)  In the event that the Stockholders fail to exercise in full the right
of first refusal within said 15 day period, the Company shall have 90 days
thereafter to sell the New Securities with respect to which the Stockholders'
rights were not exercised, at a price and upon general terms no more favorable
to the purchasers thereof than specified in the Company's notice. In the event
the Company has not sold the New Securities within such 90 day period, the
Company shall not thereafter issue or sell any New Securities without first
offering such securities to the Stockholders in the manner provided in this
Section 6.

     7.   FINANCIAL INFORMATION. The Company will furnish the following reports
to each of the Stockholders for so long as such Stockholder beneficially owns at
least 5% of the issued and outstanding shares of Capital Stock:

     (a)  As soon as practicable after the end of each fiscal year, a
consolidated balance sheet of the Company and its subsidiaries, if any, as of
the end of such fiscal year, and a consolidated statement of income and
consolidated statement of changes in financial position of the Company and its
subsidiaries, if any, for such year, prepared in accordance with generally
accepted accounting principles, audited and certified by independent public
accountants of nationally recognized standing selected by the Company, and
setting forth in each case in comparative form the figures for the previous
fiscal year, all in reasonable detail.

     (b)  As soon as practicable after the end of the first, second and third
quarterly accounting periods in each fiscal year of the Company (commencing with
the third quarter of 1998), a consolidated balance sheet of the Company and its
subsidiaries, if any, as of the end of each such quarterly period, and a
consolidated statement of income and consolidated statement of changes in
financial condition of the Company and its subsidiaries for such period, and for
the current fiscal year to date, prepared in accordance with generally accepted
accounting principles, all in reasonable detail and signed, subject to changes
resulting from year-end audit adjustments, by the principal financial or
accounting officer of the Company.

     8.   LEGEND ON CERTIFICATES. All certificates evidencing shares of Common
Stock now or hereinafter issued to the Stockholders will bear legends
substantially as follows:

          The shares represented by this certificate and any transfer thereof,
          whether voluntary or by operation of law, are subject to a
          Stockholders Agreement dated as of June 19, 1998, between LKQ
          Corporation and its stockholders, a copy of which is on file with the
          Secretary of LKQ Corporation. Any transfer hereof in conflict
          therewith, or in derogation thereof, is void and of no legal force and
          effect or validity whatsoever.

                                        5
<Page>

          The shares represented by this certificate were issued in reliance on
          exemptions from the registration requirements of the Securities Act of
          1933 (the "Act"), and may not be sold, assigned, pledged, or otherwise
          transferred in the absence of an effective registration under the Act
          covering the transfer, or an opinion of counsel, satisfactory to the
          Company, that registration under the Act is not required.

     9.   VOTING AGREEMENTS. (a) Each Stockholder shall vote all Capital Stock
held by such Stockholder, execute and deliver such further documents and take
such further action, all as shall be necessary to carry out the purposes and
intent of this Agreement.

          (b)  Each Stockholder shall vote the Capital Stock owned by such
Stockholder in favor of an amendment to the bylaws of the Company only if each
Stockholder which beneficially owns Capital Stock of the Company having at least
15% of the voting power of the Company votes in favor of such amendment.

          (c)  Each Stockholder represents that it is not a party to and agrees
that it shall not become a party to any voting agreement as described in Section
218(c) of the Delaware General Corporation Law, except as otherwise set forth in
this Agreement and the Voting Agreement dated as of June 19, 1998 by and among
Republic Industries, Inc., Donald F. Flynn and his family members and their
affiliates, Dean L. Buntrock and Paul M. Montrone.

     10.  POOLING TRANSACTIONS. Each Stockholder agrees that it will vote all of
its Shares in favor of a transaction involving the sale of the Company intended
to qualify as a pooling-of-interests transaction (whether in the form of a
merger, consolidation or similar corporate transaction, a stock-for-stock
transaction, or a sale of all or substantially all of the assets of the Company)
if (a) more than 80% of the outstanding shares of Capital Stock of the Company
are voted in favor of such transaction, and (b) each Stockholder which
beneficially owns Capital Stock of the Company having at least 15% of the voting
power of the Company votes in favor of such transaction.

     11.  TERM OF THIS AGREEMENT. This Agreement shall continue in full force
and effect until (a) terminated by the consent of the Stockholders beneficially
owning at least a majority of the Shares (which must include the consent of each
Stockholder which beneficially owns Capital Stock of the Company having at least
15% of the voting power of the Company); (b) any one Stockholder acquires all of
the Shares; or (c) the closing of the initial public offering of the Capital
Stock of the Company.

     12.  THIS AGREEMENT GOVERNS. In the event of any inconsistency between this
Agreement and any of the bylaws or resolutions of the board of directors or the
stockholders of the Company whether now existing or hereafter adopted, this
Agreement shall prevail and govern in the matter, and each of the Stockholders
hereby agrees that it will not, whether as a stockholder, director or officer,
cause the Company to take any action inconsistent with this Agreement. No shares
of Capital Stock will be transferred on the books of the Company, nor will any
Transfer be effective, nor shall any additional shares or any rights or options
to acquire any shares be valid or effective, unless and until such action is in
compliance with all of the terms and conditions of this Agreement.

                                        6

     13.  SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon and shall
inure to the benefit of the respective parties hereto, and to the extent
permitted hereby, their respective successors, personal representatives,
spouses, legatees, heirs and assigns, but the foregoing does not imply, nor is
it intended to modify the obligations of the parties hereto with respect to
transferring or acquiring shares of Capital Stock or any interest therein,
except in accordance with the terms of this Agreement.

     14.  ASSURANCES. The Stockholders, by the signing hereof, hereby agree to
execute and deliver such other documents and agreements, including but not
limited to assignments, bills of sale, stock powers, or resolutions, as may be
reasonably necessary, desirable or convenient in order to effectuate the
purposes of this Agreement.

     15.  HEADINGS. All section headings and paragraph titles or captions
contained in this Agreement are for convenience of reference only and shall not
be deemed to modify, describe, limit, extend or define the terms hereof, or the
scope of this Agreement, nor are they relevant to the intent of any provision
hereof.

     16.  PRONOUNS. All pronouns and any variations thereof shall be deemed to
refer to the neutral, masculine, feminine, singular and plural as the identity
of that person referred to requires.

     17.  NOTICE. All notices, requests, demands, consents and other
communications required or permitted to be given pursuant to this Agreement
shall be in writing and delivered by hand, by overnight courier delivery service
or by certified mail, return receipt requested, postage prepaid. Notices shall
be deemed given when actually received, which shall be deemed to be not later
than the next business day if sent by overnight courier or after five business
days if sent by mail. Notice to Stockholders shall be made to the address listed
on the stock transfer records of the Company. Any notice to a party to this
Agreement may include a provision stating that failure to respond to the notice
within ten business days of receipt thereof (or such longer period of time as
otherwise provided in this Agreement with respect to a specified notice) shall
be deemed to be the consent of such party to the matter set forth in such
notice, and all other parties to this Agreement shall be entitled to rely and
act on such consent.

     18.  COUNTERPARTS. This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

     19.  VALIDITY. If any provision in this Agreement shall be held to be
invalid, illegal or unenforceable in any respect, such invalid, illegal or
unenforceable provision shall not affect any other provision hereof, and this
Agreement shall be construed as if such invalid, illegal or unenforceable
provision had never been contained herein.

     20.  AMENDMENTS. It is mutually understood and agreed that this Agreement
sets forth the entire agreement and understanding between the parties hereto
with respect to the subject matter hereof, and that this Agreement supersedes
all prior agreements and understandings among the parties hereto and shall not
be supplemented, modified or amended except by a written instrument, dated
subsequent to the date hereof, signed by (a) a duly authorized officer of the

                                        7
<Page>

Company; and (b) Stockholders beneficially owning at least a majority of the
Shares (which concurrence must include each Stockholder which beneficially owns
Capital Stock having at least 15% of the voting power of the Company).

     21.  REMEDIES. The parties hereto acknowledge the Capital Stock is a unique
chattel and possesses a special, unique and extraordinary character, which would
make it difficult to assess the monetary damage which any party hereto would
sustain in the event of a breach of this Agreement. The parties hereto expressly
recognize and agree that irreparable injury would be caused to any party to this
Agreement by a breach of any of the terms or conditions of this Agreement, and
therefore agree that the equitable remedies of specific performance or
preliminary or injunctive relief would be appropriate in the event of a breach
of this Agreement, provided that such remedies shall not be exclusive of other
remedies available.

     22.  APPLICABLE LAW. This Agreement shall be governed by and construed in
accordance with the laws of the State of Delaware (without regard to the
conflict laws thereof).

                            *          *          *

                                        8

caused this Agreement to be executed as of the day and year first above written.
