Delaware corporation ("Acquiror"), KEYSTONE AUTOMOTIVE OPERATIONS, INC., a

                              W I T N E S S E T H:

          WHEREAS, Acquiror, Keystone Merger Sub, Inc., a Pennsylvania
corporation and a wholly-owned subsidiary of Acquiror ("Merger Sub"), the

capitalized terms used herein and not defined herein have the respective
meanings ascribed to them in the Merger Agreement), pursuant to which Merger Sub
will be merged with and into the Company, with the Company continuing as the
Surviving Corporation and a wholly-owned subsidiary of Acquiror (the "Merger");

          WHEREAS, each of the Shareholders owns the number of shares of (i)
Common Stock, par value $.01 per share (the "Common Stock"), and (ii) Series A
Preferred Stock, stated value $649.99 per share (the "Series A Preferred Stock",

Company held by such Shareholders, the "Shares"), of the Company set forth
opposite such Shareholder's name on Exhibit A hereto; and

          WHEREAS, the Shareholders have agreed to enter into this Agreement
strictly in their capacity as owners of the Shares and not in their capacity as
directors or officers of the Company.

          NOW, THEREFORE, to induce Acquiror and Merger Sub to enter into the
Merger Agreement, and in consideration of the premises and the representations,
warranties, covenants and agreements contained herein, and intending to be
legally bound hereby, the parties hereto hereby agree as follows:

          1. Provisions Concerning the Shares.

          (a) Each Shareholder hereby agrees that during the period commencing
on the date hereof and continuing until this provision terminates pursuant to
Section 7 hereof, at any meeting of shareholders of the Company, however called,
or in connection with any written consent of the shareholders of the Company,
such Shareholder shall vote (or cause to be voted) the Shares held of record or
beneficially owned by such Shareholder, whether heretofore owned or hereafter
acquired, and shall exercise (or cause to be exercised) all consensual rights
attendant thereto (i) in favor of approval of the Merger Agreement and the
transactions contemplated thereby (including the Merger) and any actions
required in furtherance thereof and hereof; (ii) against any

<PAGE>

action or agreement that would result in a breach in any respect of any
covenant, representation or warranty or any other obligation or agreement of the
Company under the Merger Agreement; (iii) in favor of any amounts proposed to be
paid to directors, employees or former employees of the Company under the
Keystone Automotives Operations, Inc. 2003 Transaction Bonus Plan and submitted
to shareholders of the Company for their approval in a manner intended to
satisfy the requirements of Section 280G(b)(5) of the Internal Revenue Code; and
(iv) except as otherwise contemplated or permitted by the Merger Agreement,
against the following actions (other than the Merger and the transactions
contemplated by the Merger Agreement): (A) any Alternative Transaction; (B) a
sale, lease or transfer of a material amount of assets of the Company, or a
reorganization, recapitalization, dissolution or liquidation of the Company; (C)
any change in a majority of the persons who constitute the board of directors of
the Company or a change in management of the Company; (D) any amendment of the
Company's articles of incorporation or by-laws; or (E) any other action which is
intended, or could reasonably be expected, to impede, interfere with, delay,
postpone, or adversely affect the Merger and the transactions contemplated by
this Agreement and the Merger Agreement. In the event that any corporate action
consistent with this Agreement is taken by the shareholders of the Company by
written consent (including any action to approve the Merger Agreement and the
transactions contemplated thereby), each Shareholder hereby waives any right to
receive notice of the taking of such corporate action without a meeting pursuant
to Section 1766 of the Pennsylvania Business Corporation Law of 1988 (the "BCL")
or otherwise.

          (b) Each Shareholder hereby agrees that it will execute and deliver
the Holder Representative Agreement before the Effective Time of the Merger.

          (c) In the event of a stock dividend or distribution, or any change in
the capital stock of the Company by reason of any stock split, recapitalization,
reclassification, combination, exchange of shares, merger or similar event, the
term "Shares" as used in this Agreement shall be deemed to refer to and include
the Shares as well as all such stock dividends and distributions and any shares
or other securities into which or for which any or all of the Shares may be
converted, changed or exchanged.

          2. Waiver of Appraisal Rights. Each Shareholder hereby irrevocably
waives any rights to appraisal of the fair value of such Shareholder's Shares,
rights to dissent from the Merger or other similar rights that such Shareholder
may have pursuant to the BCL or otherwise (collectively, "Appraisal Rights").

          3. Representations and Warranties. Each Shareholder hereby represents
and warrants to Acquiror and the Holder Representative as follows:

          (a) Ownership of Shares. Such Shareholder is the record and, except as
set forth on Schedule 3(a) attached hereto, beneficial owner of the number of
Shares set forth opposite such Shareholder's name on Exhibit A hereto. The
Shares set forth opposite such Shareholder's name on Exhibit A hereto constitute
all of the Shares owned of record or beneficially owned by such Shareholder.
Except as set forth on Schedule 3(a) attached hereto, such Shareholder has the
requisite power (i) to vote and to issue

                                      -2-

<PAGE>

instructions with respect to the matters set forth in Sections 1 and 5 hereof,
(ii) to dispose of, and (iii) to demand Appraisal Rights, in each case with
respect to all of the Shares set forth opposite such Shareholder's name on
Exhibit A hereto.

          (b) Power; Binding Agreement. Such Shareholder has the requisite power
and authority (or, if a natural person, the legal capacity) to enter into and
perform all of such Shareholder's obligations under this Agreement. This
Agreement has been duly and validly authorized, executed and delivered by such
Shareholder and constitutes a valid and binding agreement of such Shareholder,
enforceable against such Shareholder in accordance with its terms, subject to
applicable bankruptcy, insolvency, fraudulent conveyance, reorganization,
moratorium and similar laws affecting creditors' rights and remedies generally,
and subject, as to enforceability, to general principles of equity, including
principles of commercial reasonableness, good faith and fair dealing (regardless
of whether enforcement is sought in a proceeding at law or in equity). Except as
have been obtained, there is no beneficiary or holder of a voting trust
certificate or other interest of any trust of which such Shareholder is settlor
or trustee or any other person whose consent is required for the execution and
delivery of this Agreement or the performance by such Shareholder of its
obligations hereunder.

          (c) No Conflicts. (i) No filing with, and no permit, authorization,
consent or approval of, any state or federal public body or authority is
necessary for the execution of this Agreement by such Shareholder and the
consummation by such Shareholder of the transactions contemplated hereby, and
(ii) none of the execution, delivery and performance of this Agreement by such
Shareholder will (A) result in a violation or breach of, or constitute (with or
without notice or lapse of time or both) a default under any declaration of
trust, note, bond, mortgage, indenture, security or pledge agreement, voting
agreement, shareholders agreement or voting trust, license, contract,
commitment, arrangement, understanding, agreement or other instrument or
obligation of any kind to which such Shareholder is a party or by which such
Shareholder or any of such Shareholder's properties or assets is bound, (B)
violate any order, writ, injunction, decree, judgment, order, statute, rule or
regulation of any Governmental Authority applicable to such Shareholder or any
of such Shareholder's properties or assets, in each case where any such
violation, breach or default would disable or prevent such Shareholder from
executing and delivering this Agreement and performing its obligations
hereunder, or (C) violate any provisions of the Company's articles of
incorporation or by-laws.

          (d) No Encumbrances. Except as applicable in connection with the
transactions contemplated hereby, such Shareholder's Shares and the certificates
representing such Shares are now, and will be, at all times during the term
hereof, beneficially owned and held of record by such Shareholder, free and
clear of all liens, claims, security interests, proxies, voting trusts or
agreements, understandings or arrangements or any other encumbrances whatsoever,
except for any such encumbrances: (i) arising hereunder; (ii) existing under any
pledge agreement executed by a Shareholder in favor of Wachovia Bank N.A.
(formerly known as First Union National Bank), as agent (the "Agent"), in
connection with the Credit Agreement (each, a "Pledge Agreement"); (iii)
existing under the Shareholders' Agreement and the Registration

                                      -3-

<PAGE>

Rights Agreement; (iv) existing under any Restricted Stock Agreements or
Restricted Stock Agreement and Amendment to Stock Option Agreements; and (v)
existing under the Securities Act of 1933, as amended.

          4. No Solicitation.

          (a) Immediately after the execution of this Agreement, and continuing
until this provision terminates pursuant to Section 7 hereof, each Shareholder
shall terminate and cease, and shall direct its Affiliates, officers, directors,
Representatives and agents (such Persons collectively shall be referred to as
the "Shareholder Group") to terminate and cease, all discussions and
negotiations that may then be ongoing by any of them with respect to an
Alternative Transaction. From the date hereof through the earlier of (a) the
Closing or (b) the termination of this provision pursuant to Section 7 hereof,
the Shareholder shall not, and shall not knowingly permit any member of the
Shareholder Group to, directly or indirectly, solicit, participate in or
initiate discussions or negotiations with, or provide any information to, any
Person or group of Persons (other than Acquiror, Merger Sub or any of their
respective Affiliates) concerning any Alternative Transaction. The Shareholder
shall notify Acquiror within two Business Days if it receives a bona fide,
written offer in respect of an Alternative Transaction.

          (b) Each of Acquiror and the Holder Representative acknowledges that
this Agreement is entered into by each Shareholder in such Shareholder's
capacity as an owner of the Shares, and that nothing in this Agreement shall in
any way restrict or limit a Shareholder who is also a director or officer of the
Company from taking any action in his capacity as a director or officer of the
Company or otherwise fulfilling his fiduciary obligations as a director or
officer of the Company, notwithstanding that any such action would be
inconsistent with or violative of such Shareholder's obligations under this
Agreement if taken in his capacity as an owner of the Shares.

          5. Restriction on Transfer; Stop Transfer.

          (a) Each Shareholder agrees not to, during the period commencing on
the date hereof and continuing until this provision terminates pursuant to
Section 7 hereof: (i) except as contemplated by the Merger Agreement, offer for
sale, sell, transfer, tender, pledge, encumber, assign or otherwise dispose of,
or grant or enter into any contract, option or other arrangement or
understanding with respect to or consent to the offer for sale, sale, transfer,
tender, pledge, encumbrance, assignment or other disposition of, any or all of
such Shareholder's Shares or any interest therein, provided that any Shareholder
may offer to sell, sell, transfer, assign or otherwise dispose of Shares to such
Shareholder's Affiliate who is, or as a condition precedent becomes, a party to
this Agreement, or to any other shareholder of the Company who is, or as a
condition precedent becomes, a party to this Agreement; (ii) except as
contemplated by this Agreement, grant any proxies or powers of attorney, deposit
any Shares into a voting trust or enter into a voting agreement with respect to
any Shares; or (iii) knowingly take any action that would make any of such
Shareholder's representations or warranties contained herein untrue or incorrect
or have the effect of preventing or disabling such Shareholder from performing
such Shareholder's obligations under this Agreement.

                                      -4-

<PAGE>

          (b) Without limiting the generality of Section 5(a) above, each
Shareholder agrees with, and covenants to, the Company and the Holder
Representative that such Shareholder shall not, during the period set forth in
Section 5(a), request that the Company register the transfer (book-entry or
otherwise) of any certificate or uncertificated interest representing the
Shares, unless such transfer is made in compliance with this Agreement.

          6. Grant of Irrevocable Proxy Coupled with an Interest.

          (a) During the period commencing on the date hereof and continuing
until this provision terminates pursuant to Section 7 hereof, each Shareholder
hereby irrevocably appoints the Holder Representative or any individual
designated by the Holder Representative as such Shareholder's agent,
attorney-in-fact and proxy (with full power of substitution), for in the name,
place and stead of such Shareholder, to vote (or cause to be voted) the Shares
held of record or beneficially owned by such Shareholder, whether issued,
heretofore owned or hereafter acquired, or grant a consent or approval in
respect of such Shares, at any meeting of Shareholders of the Company or at any
adjournment thereof or in any other circumstances upon which his, her or its
vote, consent or other approval is sought: (i) in favor of the approval of the
Merger Agreement and any actions required in furtherance thereof and hereof;
provided, however, that if the Holder Representative fails to vote the Shares in
favor of the approval of the Merger Agreement or any actions required in
furtherance thereof, each Shareholder shall be deemed to have appointed the
Acquiror as such Shareholder's agent, attorney-in-fact and proxy (with full
power of substitution), for in the name, place and stead of such Shareholder, to
vote (or cause to be voted) the Shares held of record or beneficially owned by
such Shareholder in favor of the approval of the Merger Agreement and any
actions required in furtherance thereof; (ii) against any action or agreement
that would result in a breach in any respect of any covenant, representation or
warranty or any other obligation or agreement of the Company under the Merger
Agreement; (iii) in favor of any amounts proposed to be paid to directors,
employees or former employees of the Company under the Keystone Automotives
Operations, Inc. 2003 Transaction Bonus Plan and submitted to shareholders of

Merger and the transactions contemplated by this Agreement and the Merger
Agreement.

Section 6 is coupled with an interest and is irrevocable until such time as this
Agreement

                                      -5-

terminates in accordance with its terms. Such Shareholder hereby further affirms
that the irrevocable proxy is given in connection with the execution of the
Merger Agreement, and that such irrevocable proxy is given to secure the
performance of the duties of such Shareholder under this Agreement. Such
Shareholder hereby ratifies and confirms all that such irrevocable proxy may
lawfully do or cause to be done by virtue hereof. Such irrevocable proxy is
executed and intended to be irrevocable in accordance with the provisions of
Section 1759 of the BCL.

          (c) The vote of the proxyholder shall control in any conflict between
the vote by the proxyholder of such Shareholder's Shares and a vote by such

them, solely in such Shareholder's capacity as a shareholder of the Company,

               by all the provisions of said Voting Agreement and Irrevocable

          (c) Entire Agreement. This Agreement constitutes the entire agreement
between the parties with respect to the subject matter hereof and supersedes all
other prior agreements and understandings, both written and oral, between the
parties with respect to the subject matter hereof.

          (d) Assignment. This Agreement shall not be assigned by any party
hereto, by operation of law or otherwise, without the prior written consent of
the other parties, and any purported assignment without such consent shall be
null and void; provided, however, that the Holder Representative may assign, in
its sole discretion, its rights and obligations hereunder to any successor
Holder Representative appointed in accordance with the Merger Agreement;
provided, further, that the Acquiror may assign, in its sole discretion, its
rights and obligations hereunder to any controlled Affiliate of the Acquiror.
All covenants and agreements contained in this Agreement by or on behalf of the
parties hereto shall be binding upon and inure to the benefit of the parties
hereto and their respective permitted successors and assigns.

          (e) Amendments. This Agreement may be amended or modified in whole or
in part, only by a duly authorized agreement in writing executed in the same
manner as this Agreement and which makes reference to this Agreement; provided,
however, Exhibit A may be amended by the Holder Representative to add additional
Shareholders.

          (f) Notices. All notices, requests and other communications to any
party hereunder shall be in writing (including facsimile transmission) and shall
be given

                                      -7-

<PAGE>

by (i) courier service guaranteeing either same day or next business day
delivery, (ii) United States overnight express mail, return receipt requested,
or (iii) facsimile transmission. All such notices, requests and communications
hereunder shall be delivered to the respective parties at the following

the place of receipt and such day is a Business Day in the place of receipt.
Otherwise, any such notice, request or communication shall be deemed not to have
been received until the next succeeding Business Day in the place of receipt.

          (g) Severability. If any provision of this Agreement is held invalid
or unenforceable by any court of competent jurisdiction, the other provisions of
this Agreement will remain in full force and effect. The parties further agree
that if any provision contained herein is, to any extent, held invalid or
unenforceable in any respect under the laws governing this Agreement, they shall
take any actions necessary to render the remaining provisions of this Agreement
valid and enforceable to the fullest extent permitted by law and, to the extent
necessary, shall amend or otherwise modify this Agreement to replace any
provision contained herein that is held invalid or unenforceable with a valid
and enforceable provision giving effect to the intent of the parties.

          (h) Specific Performance. Each Shareholder recognizes and acknowledges
that a breach by it of any covenant or agreement contained in this Agreement
will cause Acquiror and the Holder Representative to sustain damages for which
they would not have an adequate remedy at law for money damages, and therefore
such Shareholder agrees that in the event of any such breach Acquiror and the
Holder Representative, and each of them, shall be entitled to seek the remedy of
specific performance of such covenants and agreements and injunctive and other
equitable relief in addition to any other remedy to which Acquiror and the
Holder Representative, or each of them, may be entitled, at law or in equity.
Each Shareholder, to the maximum extent permitted by law, hereby waives any
defenses such Shareholder may have to the remedy of specific performance
provided for herein.

          (i) Remedies Cumulative. All rights, powers and remedies provided
under this Agreement or otherwise available in respect hereof at law or in
equity shall be cumulative and not alternative, and the exercise of any thereof
by any party shall not preclude the simultaneous or later exercise of any other
such right, power or remedy by such party.

          (j) No Waiver. The failure of any party hereto to exercise any right,
power or remedy provided under this Agreement or otherwise available in respect
hereof at law or in equity, or to insist upon compliance by any other party
hereto with its

                                      -8-

<PAGE>

obligations hereunder, and any custom or practice of the parties at variance
with the terms hereof, shall not constitute a waiver by such party of its right
to exercise any such or other right, power or remedy or to demand such
compliance.

          (k) No Third Party Beneficiaries. This Agreement is not intended to be
for the benefit of, and shall not be enforceable by, any Person who or which is
not a party hereto.

          (l) Obligations Several and Not Joint. The obligations of each
Shareholder under and pursuant to this Agreement are several and not joint with
any other Shareholder.
