                                LOCK-UP AGREEMENT

         THIS LOCK-UP AGREEMENT ("Agreement") dated as of June 24, 1999, between
Group 1 Automotive, Inc., a Delaware corporation (the "Company") and the
undersigned holder ("Stockholder") of Common Stock of the Company.

         WHEREAS, the Company has requested that the Stockholder agree not to
sell any shares of Common Stock of the Company until July 15, 2000, except in an
offering registered with the Securities and Exchange Commission ("SEC")
initiated by the Company; and

         WHEREAS, in consideration of Stockholder agreeing not to sell shares of
Common Stock of the Company, the Company has agreed to initiate an offering
registered with the SEC of a portion of the shares of Common Stock of the
Company held by Stockholder.

         NOW, THEREFORE, for and in consideration of the above premises and
other good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, the parties hereto hereby agree as follows.

         1. Stockholder is the beneficial owner of the number of shares of
Common Stock of the Company set forth after his name on Schedule I attached
hereto and desires to sell up to the number of shares of Common Stock of the
Company set forth after his name on Schedule I attached hereto in an offering
registered with the SEC.

         2. Stockholder hereby irrevocably agrees, except for the number of
shares of the Company set forth after his name on Schedule I attached hereto to
be included in a registration statement to be filed with the SEC and sold in an
offering registered with the SEC as shall be determined by the Company, that
Stockholder will not, directly or indirectly, sell, lend, offer, contract to
sell, transfer the economic risk of ownership in, make any short sale, pledge or
otherwise dispose of or transfer any shares of Common Stock or any securities
convertible into or exchangeable or exercisable for or any other rights to
purchase or acquire Common Stock without the prior written consent of the
Company for a period from the date hereof until the earliest of (i) 60 days
following the death of Stockholder; (ii) 60 days following the time at which
Stockholder is determined to be "permanently disabled" (for purposes of the
immediately preceding sentence, "permanently disabled" shall mean a condition
(certified by a licensed physician, selected by the Company) rendering
Stockholder unable to engage in employment that is substantially similar to
Stockholder's current employment); or (iii) July 15, 2000. Notwithstanding the
foregoing, if Stockholder is an individual, he or she may transfer any shares of
Common Stock or securities convertible into or exchangeable or exercisable for
Common Stock either during his or her lifetime or on death by will or intestacy
to his or her immediate family or to a trust the beneficiaries of which are
exclusively the undersigned and/or a member or members of his or her immediate
family; provided, however, that prior to any such transfer each transferee shall
execute an agreement, satisfactory to the Company, pursuant to which each
transferee shall agree to receive and hold such
<PAGE>   2

shares of Common Stock, or securities convertible into or exchangeable or
exercisable for the Common Stock, subject to the provisions hereof, and there
shall be no further transfer except in accordance with the provisions hereof.
For the purposes of this paragraph, "immediate family" shall mean spouse, lineal
descendant, father, mother, brother or sister of the transferor. The Stockholder
understands that the agreements of the Stockholder are irrevocable and shall be
binding upon the Stockholder's heirs, legal representatives, successors and
assigns.

         3. Whether or not the offering registered with the SEC actually occurs
depends on a number of factors, including market conditions. Any offering
registered with the SEC will only be made pursuant to one or more agreements
(each a "Purchase Agreement"), the terms of which are subject to agreement
between the Company and either the underwriters, dealers, agents or direct
purchasers (the "Purchasers"), depending on the type of offering. The
Stockholder agrees and consents to the entry of stop transfer instructions with
the Company's transfer agent against the transfer of Common Stock or other
securities of the Company held by the Stockholder except in compliance with this
Agreement.

         4. Attached hereto as Appendix A is a form of Power of Attorney and
Custody Agreement that the Stockholder agrees to execute contemporaneous with
the execution of this Agreement.

         5. The Company shall, as expeditiously as reasonably possible, and in
any case prior to August 1, 1999, prepare and file with the SEC a registration
statement with respect to the shares of Common Stock that Stockholder desires to
sell as set forth in paragraph 1 and use its best efforts to cause such
registration statement to become and remain effective; provided, however, that
the Company shall have no obligation to maintain the effectiveness of any
registration statement filed hereunder or to cause the information therein to
remain current for more that such period as is customary and is required by the
Purchaser in the offering registered with the SEC. The Company shall select the
Purchaser or Purchasers, as the case may be, with respect to the offering of the
shares of Common Stock held by the Stockholder. The Company shall cooperate with
the Purchasers as the Purchasers may reasonably request in facilitating the
offering registered with the SEC.

         6. All expenses incurred in connection with a registration statement
pursuant to this Agreement, including without limitation all registration and
qualification fees, printing and accounting fees, and fees and disbursements of
counsel for the Company and the Stockholder, shall be borne by the Company. The
Stockholder shall pay the Purchasers' discounts and commissions applicable to
the Common Stock sold by the Stockholder. In addition, the Stockholder shall pay
his or her own costs for experts or professionals (other than counsel) employed
by the Stockholder or on his or her behalf in connection with the registration
of the Common Stock under this Agreement.

         7. The Company agrees to indemnify the Stockholder with respect to the
offering registered with the SEC of Common Stock pursuant to this Agreement as
set forth in Appendix B attached hereto.

Gentlemen:

         Group 1 Automotive, Inc., a Delaware corporation (the "Company"), the
undersigned and certain other stockholders of the Company (the undersigned and
such other stockholders being hereinafter referred to as the "Selling
Stockholders") may sell certain shares of Common Stock, par value $.01 per
share, of the Company ("Common Stock") covered by a Registration Statement on
Form S-3, as amended from time to time filed with the Securities and Exchange
Commission (the "Registration Statement") through underwriters, dealers, agents
or directly to one or more purchasers (collectively, the "Purchasers") as
contemplated by the Registration Statement. It is understood that at this time
there is no commitment on the part of any Purchaser to purchase any shares of
Common Stock and the undersigned acknowledges that no assurance can be given
that an offering of Common Stock will take place. The number of shares of Common
Stock that the undersigned proposes to sell to the Purchasers (the "Shares") are
set forth on Schedule I hereto. This Custody Agreement and Power of Attorney is
referred to herein as this "Agreement."

         be sold to the Purchasers at a price per share less than $20;

                           (iii) prepare, execute and deliver one or more

         the terms of which are subject to agreement between the Company and the
         Purchasers, including the making of all representations and agreements
         provided in the applicable Purchase Agreement to be made by, and the
         exercise of all authority thereunder vested in, the undersigned;

                           (iv) sell, assign, transfer and deliver the Shares to
         the Purchasers pursuant to the applicable Purchase Agreement and

         "Securities Act" ), the Securities Exchange Act of 1934, as amended,
         and under the securities or "blue sky" laws of various states and
         jurisdictions, including, without limitation, the giving or making of
         such undertakings, representations and agreements and the taking of
         such other steps as the Attorneys-in-Fact may deem necessary or
         advisable;

                           (vi) instruct the Company and the Custodian, as

         Registration Statement;

                           (viii) retain such legal counsel as the
         Attorneys-in-Fact or any of them in their sole discretion deem
         appropriate (which may be the same as the Company's counsel), to act as

         such counsel being hereby authorized to rely upon the representations
         and warranties of the undersigned contained in the applicable Purchase
         Agreement and in Section 4 of this Agreement in acting in such
         capacity; and

                           (ix) otherwise take all actions and do all things
         necessary or proper, required, contemplated or deemed advisable or
         desirable by the Attorneys-in-Fact in their discretion, including the
         execution and delivery of any documents, and generally act for and in
         the name of the undersigned with respect to the sale of the Shares to
         the Purchasers and the reoffering of the Shares by the Purchasers as
         fully as could the undersigned if then personally present and acting.

<PAGE>   6

                  (b) Each Attorney-in-Fact may act alone or in concert in
exercising the rights and powers conferred on the Attorneys-in-Fact by this
Custody Agreement and Power of Attorney, and the act of any Attorney-in-Fact
shall be the act of the Attorneys-in-Fact. Each Attorney-in-Fact is hereby
empowered to determine, in his sole and absolute discretion, the time or times
when, the purposes for which, and the manner in which, any power herein
conferred upon the Attorneys-in-Fact shall be exercised.

                  (c) The Custodian, the Purchasers, the Company and all other
persons dealing with the Attorneys-in-Fact as such may rely and act upon any
writing believed in good faith to be signed by one or more of the
Attorneys-in-Fact.

                  (d) The Attorneys-in-Fact shall not receive any compensation
for their services rendered hereunder, except that they shall be entitled to
cause the Custodian to pay, from the proceeds payable to the undersigned, the
undersigned's proportionate share of any out-of-pocket expenses incurred under
this Agreement and similar instruments executed by other Selling Stockholders.

         2. APPOINTMENT OF CUSTODIAN; DEPOSIT OF SHARES.

                  (a) In connection with and to facilitate the sale of the
Shares to the Purchasers, the undersigned hereby appoints Scott L. Thompson, as
custodian (the "Custodian") and herewith deposits with the Custodian one or more
certificates for Common Stock. The certificate(s) for Shares deposited hereunder
represent currently owned Shares at least equal in number in the aggregate to
the total number of Shares to be sold by the undersigned to the Purchasers,
which number is set forth on Schedule I hereto. Each such certificate for Shares
so deposited hereunder is in negotiable and proper deliverable form endorsed in
blank with the signature of the undersigned thereon guaranteed by a commercial
bank or trust company in the United States or by a member firm of the New York
Stock Exchange, or is accompanied by a duly executed stock power or powers in
blank, bearing the signature of the undersigned so guaranteed. The Custodian is
hereby authorized and directed, subject to the instructions of the
Attorneys-in-Fact, (a) to hold in custody any certificates for Shares deposited
herewith, (b) to deliver or to authorize the Company's Transfer Agent to deliver
the certificates for Shares deposited hereunder (or replacement certificate(s)
for the Shares) to or at the direction of the Attorneys-in-Fact in accordance
with the applicable Purchase Agreement and (c) to return or cause the Company's
Transfer Agent to return to the undersigned new certificate(s) for the shares of
Common Stock represented by any certificate for Common Stock deposited hereunder
which are not sold pursuant to the applicable Purchase Agreement.

                  (b) Until the Shares have been delivered to the Purchasers
against payment therefor in accordance with the applicable Purchase Agreement,
the undersigned shall retain all rights of ownership with respect to the Shares
deposited hereunder, including, if applicable, the right to vote and to receive
all dividends and payment thereon, except the right to retain custody of or
dispose of such Shares (but only to the extent provided herein), which right is
subject to this Agreement.

<PAGE>   7

         3. SALE OF SHARES; REMITTING NET PROCEEDS.

                  (a) The Attorneys-in-Fact are hereby authorized and directed
to deliver or cause the Custodian or the Company's Transfer Agent to deliver
certificates for the Shares to the Purchasers, in accordance with the applicable
Purchase Agreement, against delivery to the Attorneys-in-Fact for the account of
the undersigned of the purchase price of the Shares, at the time and in the
funds specified in the applicable Purchase Agreement. The Attorneys-in-Fact are
authorized, on behalf of the undersigned, to accept and acknowledge receipt of
the payment of the purchase price for the Shares and shall promptly deposit such
proceeds with the Custodian. After reserving an amount of such proceeds for
expenses as provided below, the Custodian shall promptly remit to the
undersigned his proportionate share of the proceeds.

                  (b) Before any proceeds of the sale of the Shares are remitted
to the undersigned, the Attorneys-in-Fact are authorized and empowered to direct
the Custodian to reserve from the proceeds an amount determined by the
Attorneys-in-Fact to be sufficient to pay the undersigned's proportionate share
of all expenses to be paid by the Selling Stockholders. The Custodian is
authorized to pay all of the Selling Stockholders' expenses relating to the
offering from the amount reserved for that purpose pursuant to the direction of
the Attorneys-in-Fact. After payment of expenses, the Custodian will remit to
the undersigned his proportionate share of any balance. To the extent expenses
exceed the amount reserved, each Selling Stockholder shall remain liable for his
proportionate share of such expenses. The Selling Stockholders' expenses shall
include all discounts and commissions applicable to the sale of the Shares and,
to the extent applicable to such Selling Stockholder, all costs for experts or
professionals (other than counsel) employed by or on behalf of such Selling
Stockholder in connection with the registration and sale of the Shares.

         4. REPRESENTATIONS, WARRANTIES AND AGREEMENTS. The undersigned
represents and warrants to, and agrees with, the other Selling Stockholders, the
Company, the Attorneys-in-Fact, the Custodian and the Purchasers as follows:

                  (a) The undersigned has and, on each date on which the

                  (b) The undersigned has reviewed a draft of the applicable

representations and warranties to be made by the undersigned as a Selling
Stockholder and the indemnification and contribution provisions contained
therein insofar as such provisions relate to the undersigned. The undersigned
hereby represents, warrants and covenants that each of the representations and
warranties of the Selling Stockholders contained in the applicable Purchase
Agreement is true and correct with respect to the undersigned as of the date
hereof and, except as the undersigned shall have notified the Attorneys-in-Fact
pursuant to

<PAGE>   8

paragraph I of the attached instructions, will be true and correct at all times
from the date hereof through and including each Time of Delivery (as such terms
are defined in the applicable Purchase Agreement). The undersigned will promptly
notify the Attorneys-in-Fact of any development that would make any such
representation and warranty untrue.

                  (c) The undersigned has read Schedule II and Schedule III
attached hereto and has supplied the information called for therein, and the
information contained in Schedule II and Schedule III attached hereto supplied

                  (d) Upon execution and delivery of the applicable Purchase
Agreement by the Attorneys-in-Fact on behalf of the undersigned, the undersigned
agrees to be bound by and to perform each of the covenants and agreements
(including, without limitation, those relating to indemnification and
contribution, as well as the "lockup" provisions contained therein) of the
undersigned as a Selling Stockholder in the applicable Purchase Agreement.

                  (e) The undersigned agrees to deliver to the Attorneys-in-Fact
such documentation as the Attorneys-in-Fact, the Company, the Selling
Stockholders or the Purchasers or any of their respective counsel may reasonably
request in order to effectuate any of the provisions hereof or of the applicable
Purchase Agreement, all of the foregoing to be in form and substance
satisfactory in all respects to the Attorneys-in-Fact.

The foregoing representations, warranties and agreements are made for the
benefit of, and may be relied upon by, the other Selling Stockholders, the
Attorneys-in-Fact, the Company, the Custodian, the Purchasers and their
respective representatives, agents and counsel and are in addition to, and not
in limitation of, the representations, warranties and agreements of the Selling
Stockholders in the applicable Purchase Agreement.

         5. IRREVOCABILITY OF INSTRUMENTS; TERMINATION OF THIS AGREEMENT.

                  (a) This Agreement, the deposit of certificates pursuant
hereto and all authority hereby conferred, is granted, made and conferred
subject to and in consideration of (i) the interests of the Attorneys-in-Fact,
the Purchasers, the Company and the other Selling Stockholders who may become
parties to the applicable Purchase Agreement in and for the purpose of
completing the transactions contemplated hereunder and by the applicable
Purchase Agreement and (ii) the completion of the registration of Common Stock
pursuant to the Registration Statement and the other acts of the above-mentioned
parties from the date hereof to and including the execution and delivery of the
applicable Purchase Agreement in anticipation of the sale of Common Stock,
including the Shares, to the Purchasers; and the Attorneys-in-Fact are hereby
further vested with an estate, right, title and interest in and to the
certificates deposited herewith for the purpose of irrevocably empowering and
securing to them authority sufficient to consummate said transactions.
Accordingly, this Agreement shall be irrevocable prior to the earliest of (b) 60
days following the death of Stockholder, (a) 60 days following the time at which
Stockholder is determined to be "permanently disabled" (for purposes of the
immediately preceding sentence, "permanently disabled" shall mean a condition
(certified by a licensed physician, selected by the Company) rendering
Stockholder unable to engage in employment that is substantially similar to
Stockholder's current employment), or (c) July 15, 2000,

<PAGE>   9

(the "Termination Date"); this Agreement shall remain in full force and effect
until the Termination Date, unless prior to such date the applicable Purchase
Agreement has been terminated by the Purchasers due to the failure of a
condition precedent to the closing of the transactions contemplated thereby, in
which case this Agreement shall cease to remain in full force and effect as of
such time. The undersigned further agrees that this Agreement shall not be
terminated by operation of law or upon the occurrence of any event whatsoever,
including the death, disability or incompetence of the undersigned or any other
Selling Stockholder or, if the undersigned or any other Selling Stockholder is
not a natural person, upon any dissolution, winding up, distribution of assets
or other event affecting the legal existence of the undersigned or such Selling
Stockholder. If any event referred to in the preceding sentence shall occur,
whether with or without notice thereof to the Attorneys-in-Fact, any of the
Purchasers or any other person, the Attorneys-in-Fact shall nevertheless be
authorized and empowered to deliver and dispose of the certificates deposited
under the Agreement by the undersigned in accordance with the terms and
provisions of the applicable Purchase Agreement and this Agreement as if such
event had not occurred.

                  (b) If the sale of the Shares contemplated by this Agreement
is not completed by the Termination Date, this Agreement shall terminate
(without affecting any lawful action of the Attorneys-in-Fact or the Custodian
prior to such termination), and the Attorneys-in-Fact shall cause the Custodian
to return to the undersigned all certificates deposited hereunder representing
Shares on or prior to such date, but only after having received payment of the
undersigned's proportionate part of any expenses to be paid or borne by the
Selling Stockholders. The undersigned hereby covenants with the
Attorneys-in-Fact and with all other Selling Stockholders that if for any reason
the sale of the Shares contemplated hereby shall not be consummated, the
undersigned shall pay the undersigned's proportionate share of all expenses
payable by the Selling Stockholders hereunder or under the applicable Purchase
Agreement.

         6. LIABILITY AND INDEMNIFICATION OF THE ATTORNEYS-IN-FACT AND
CUSTODIAN. The Attorneys-in-Fact and the Custodian assume no responsibility or
liability to the undersigned or to any other person, other than to hold and
dispose of the certificates and Shares, the other documents deposited hereunder,
the proceeds from the sale of the Shares and any other shares of Common Stock
deposited with the Custodian pursuant to the terms of this Agreement in
accordance with the provisions hereof. The undersigned hereby agrees to
indemnify and hold harmless the Attorneys-in-Fact and the Custodian, and their
respective officers, agents, successors, assigns and personal representatives
with respect to any act or omission of or by any of them in good faith in
connection with any and all matters contemplated by this Agreement or the
applicable Purchase Agreement. THIS SECTION 6 SHALL BE ENFORCEABLE
NOTWITHSTANDING THE SOLE, CONCURRENT, ACTIVE OR PASSIVE NEGLIGENCE OF ANY
INDEMNIFIED PARTY.

INDEMNIFICATION

                  (a) The Company will, if Common Stock held by a Stockholder is
         included in the securities as to which such registration, qualification
         or compliance is being effected, indemnify such Stockholder, each of
         its officers and directors, and each person controlling such
         Stockholder, with respect to which registration, qualification or
         compliance has been effected pursuant to this Agreement, and each
         Purchaser, if any, and each person who controls any Purchaser, against
         all claims, losses, damages and liabilities (or actions in respect
         thereof) arising out of or based on any untrue statement (or alleged
         untrue statement) of a material fact contained in any prospectus,
         offering circular or other document (including any related registration
         statement, notification or the like) incident to any such registration,
         qualification or compliance, or based on any omission (or alleged
         omission) to state therein a material fact required to be stated
         therein or necessary to make the statements not misleading, or any
         violation by the Company of any rule or regulation promulgated under
         the Securities Act of 1933, as amended (the "Act"), or of any other
         federal, state or common law applicable to the Company and relating to
         any action or inaction required of the Company in connection with any
         such registration, qualification or compliance, and will reimburse each
         such Stockholder, each of its officers and directors, and each person
         controlling such Stockholder, each such Purchaser and each person who
         controls any such Purchaser, for any legal and any other expenses
         reasonably incurred in connection with investigating or defending any
         such claim, loss, damage, liability. or action, provided that the
         Company will not be liable in any such case to the extent that any such
         claim, loss, damage, liability or expense arises out of or is based on
         any untrue statement or omission based upon written information
         furnished to the Company by an instrument duly executed by such
         Stockholder or Purchaser and stated to be specifically for use therein.
         Such indemnity shall remain in full force and effect regardless of any
         investigation made by or on behalf of such party and shall survive the
         subsequent transfer of shares of Common Stock by the seller thereof and
         the transfer of any shares of Common Stock of the Company which were
         the subject of such registration, qualification or listing.

                  (b) Each Stockholder will, if Common Stock held by such
         Stockholder is included in the securities as to which such
         registration, qualification or compliance is being effected, indemnify
         the Company, each of its directors and officers, each legal counsel and
         independent accountant of the Company, each Purchaser, if any, of the
         Company's securities covered by such a registration statement, each
         person who controls the Company or such Purchaser within the meaning of
         the Act, and each other Stockholder registering Common Stock, each of
         its officers and directors and each person controlling such
         Stockholder, against all claims, losses, damages and liabilities (or
         actions in respect thereof) arising out of or based on any untrue
         statement (or alleged untrue statement) of a material fact contained in
         any such registration statement, prospectus, offering circular or other
         document, or any omission (or alleged omission) to state therein a
         material fact required to be stated therein or necessary to

<PAGE>   13

         make the statements therein not misleading, and will reimburse the
         Company, such Stockholders, such directors, officers, persons,
         Purchasers or control persons for any legal or any other expenses
         reasonably incurred in connection with investigating or defending any
         such claim, loss, damage, liability or action, in each case to the
         extent, but only to the extent, that such untrue statement (or alleged
         untrue statement) or omission (or alleged omission) is made in such
         registration statement, prospectus, offering circular or other document
         in reliance upon and in conformity with written information furnished
         to the Company by an instrument duly executed by such Stockholder and
         stated to be specifically for use therein; provided, however, that (i)
         the obligations of such Stockholders hereunder shall be limited to an
         amount equal to the proceeds to each such Stockholder of Common Stock
         sold as contemplated herein and (ii) the indemnity for untrue
         statements or omissions described above shall not apply if the
         Stockholder providing such written information provides the Company
         with such additional written information prior to the effectiveness of
         the registration as is required to make the previously supplied written
         information true and complete, together with a description in
         reasonable detail of the information previously supplied which was
         untrue or incomplete.

                  (c) Each party entitled to indemnification hereunder (the
         "Indemnified Party") shall give notice to the party required to provide
         indemnification (the "Indemnifying Party") promptly after such
         Indemnified Party has actual knowledge of any claim as to which
         indemnity may be sought, and shall permit the Indemnifying Party to
         assume the defense of any such claim or any litigation resulting
         therefrom, provided that counsel for the Indemnifying Party, who shall
         conduct the defense of such claim or litigation, shall be approved by
         the Indemnified Party (whose approval shall not unreasonably be
         withheld), and the Indemnified Party may participate in such defense at
         such party's expense, and provided further that the failure of any
         Indemnified Party to give notice as provided herein shall not relieve
         the Indemnifying Party of its obligations under this Agreement. After
         notice from the Indemnifying Party to the Indemnified Party of its
         election to assume the defense of such claim or litigation, the
         Indemnifying Party will not be liable to such Indemnified Party for any
         legal or other expenses subsequently incurred by such Indemnified Party
         in connection with the defense thereof other than reasonable costs of
         investigation, unless the Indemnifying Party abandons the defense of
         such claim or litigation. No Indemnifying Party, in the defense of any
         such claim or litigation, shall, except with the consent of each
         Indemnified Party, consent to entry of any judgment or enter into any
         settlement which does not include as an unconditional term thereof the
         giving by the claimant or plaintiff to such Indemnified Party of a
         release from all liability in respect to such claim or litigation. No
         Indemnified Party shall consent to the entry of any judgment or enter
         into any settlement without the prior written consent of the
         Indemnifying Party.<PAGE>   1

                                  PARTICIPATION

     2.1 PARTICIPATION. Prior to each Election Date, the Committee, in its sole
discretion, shall select and notify those management or highly compensated
employees of the Employer who shall be eligible to become Members as of such
Election Date. Any such eligible employee may become a Member on such Election
Date by executing and filing with the Committee, prior to such Election Date,
the Compensation deferral election prescribed by the Committee for the Plan Year
beginning on such date. Subject to the provisions of Section 2.2, a Member shall
remain eligible to defer Compensation hereunder and receive an allocation of
Employer Deferrals for each Plan Year following his commencement of
participation in the Plan.

     2.2 CESSATION OF ACTIVE PARTICIPATION. Notwithstanding any provision
herein to the contrary, an individual who has become a Member of the Plan shall
cease to be entitled to defer Compensation hereunder and/or receive an
allocation of Employer Deferrals effective as of any date designated by the
Committee. Any such Committee action shall be communicated to the affected

     2.3 ADOPTING ENTITIES. It is contemplated that other entities may adopt

must be an Affiliate. The provisions of the Plan shall apply separately and
equally to each Employer and its employees in the same manner as is expressly
provided for the Company and its employees, except that (a) the power to appoint
or otherwise affect the Committee and the Trustee and the power to amend or
terminate the Plan or amend the Trust Agreement shall be exercised by the
Compensation Committee alone and (b) the determination of whether a Change in
Control has occurred shall be made based solely on the Company. Transfer of
employment among Employers and Affiliates shall not be considered a termination
of employment hereunder. Any Employer may, by appropriate action of its officers
without the need for approval of its board of directors (or noncorporate
counterpart) or the Committee or the Compensation Committee, terminate its
participation in the Plan. Moreover, the Compensation Committee may, in its
discretion, terminate an Employer's Plan participation at any time.

     Member's Bonus for the 1999 calendar year. If a Member elects to defer an
     integral percentage of such Member's Bonus, including a Member's Bonus for
     the 1999 calendar year, such Member may elect to establish a maximum Bonus
     deferral, the dollar amount of which such Member's Bonus deferral for any
     Plan Year shall not exceed.

In the event that a Member elects to defer an amount of Compensation pursuant to
both Section 3.1(a)(i) and 3.1(a)(ii) for any Plan Year commencing on or after
January 1, 2000, such Member may also elect to establish a maximum combined Base
Salary and Bonus deferral, the dollar amount of which such Member's combined
aggregate total of Base Salary and Bonus deferrals for such Plan Year shall not
exceed.

         (b) Paragraph (a) above notwithstanding, as of the first day of any
Plan Year commencing on or after January 1, 2000, a Member's Member Deferral
elections made pursuant to such paragraph must, in the opinion of the Committee,
be reasonably expected to result in minimum aggregate Member Deferrals for such
Member of $25,000 for such Plan Year. Member Deferral elections determined by
the Committee to not be reasonably expected to result in such minimum deferral
shall be void.

         (c) Compensation for a Plan Year not deferred pursuant to elections
under Section 3.1(a) shall be received by such Member in cash. A Member's
election to defer an amount of his Compensation pursuant to this Section 3.1
shall be made by effecting, in the form prescribed by the

                                     III-1
<PAGE>   10

Committee, a Member Deferral election pursuant to which the Member authorizes
the Employer to reduce his Compensation in the elected amount and the Employer,
in consideration thereof, agrees to credit an equal amount to such Member's
Deferral Account maintained under the Plan. The reduction in a Member's
Compensation pursuant to his Member Deferral election shall be effected by
Compensation reductions each payroll period as determined by the Committee
following the effective date of such election. Such Compensation reductions
shall be within the Plan Year to which the Member Deferral election relates,
except that Compensation reductions attributable to elections to defer a
Member's Bonus may be made within the next following Plan Year if the Bonus to
which the Member Deferral election relates is paid in such next following Plan
Year. Member Deferrals made by a Member shall be credited to such Member's
Deferral Account as of a date determined in accordance with procedures
established from time to time by the Committee; provided, however, that such
Member Deferrals shall be credited to the Member's Deferral Account no later
than 30 days after the date upon which the Compensation deferred would have been
received by such Member in cash if he had not elected to defer such amount
pursuant to this Section 3.1.

         (d) A Member Deferral election pursuant to Section 3.1 shall become
effective as of the Election Date which is immediately after the date the
election is effected by the Member and filed with the Committee. A Member
Deferral election shall remain in force and effect for the entire Plan Year to
which such election relates. A Member Deferral election shall remain in force
and effect for each subsequent Plan Year (following the Member's initial year of
participation in the Plan) for which he satisfies the eligibility requirements
set forth in Section 2.1, unless and until such election is changed or revoked
by such Member prior to the Election Date of the subsequent Plan Year to which
such change or revocation relates; provided, however, that a Member Deferral
election with respect to a Member's Bonus for the 1999 calendar year shall not
remain in force and effect for any subsequent Plan Year. Plan provisions to the
contrary notwithstanding, a Member Deferral election shall be suspended during
any period of unpaid leave of absence from the Employer and shall terminate
immediately on the date such Member incurs a Termination of Service.

         (e) A Member who has made a Member Deferral election may change his
election, as of the Election Date of any subsequent Plan Year, by effecting a
new Member Deferral election prior to such Election Date and within the time
period prescribed by the Committee.

         (f) A Member who has made a Member Deferral election may cancel his
election, as of the Election Date of any subsequent Plan Year, by effecting the
same in the form prescribed by the Committee prior to such Election Date and
within the time period prescribed by the Committee. A Member who so cancels his
Member Deferral election may again make a new Member Deferral election for a
subsequent Plan Year, if he satisfies the eligibility requirements set forth in
Section 2.1, by effecting a new Member Deferral election prior to the Election
Date of such Plan Year and within the time period prescribed by the Committee.

         (g) In the event that the Committee, upon written petition of a Member,
determines in its sole discretion that such Member has suffered an Unforeseeable
Financial Emergency or that such Member will, absent suspension of such Member's
Member Deferral election then in effect, suffer an Unforeseeable Financial
Emergency, then the Member Deferral election of such Member then in effect, if
any, shall be suspended as soon as administratively practicable after

                                     III-2
<PAGE>   11

such determination. A Member whose Member Deferral election has been so
suspended may again make a new Member Deferral election for a subsequent Plan
Year that is at least twelve months after the effective date of such suspension,
if he satisfies the eligibility requirements set forth in Section 2.1, by
effecting a new Member Deferral election for such Plan Year and within the time
period prescribed by the Committee.

     3.2 EMPLOYER DEFERRALS.

         (a) (i) For each Plan Year, the Employer shall defer an amount on
behalf of each Member (1) who makes the maximum elective deferrals permitted
under the terms of the Savings Plan for such Plan Year, (2) who has an amount
forfeited (but does not receive a distribution of such forfeited amount) from
his "Employer Contribution Account" under the Savings Plan in order to satisfy
the requirements of Code sections 401(k)(3), 401(m)(2), and/or 401(m)(9) for
such Plan Year, and (3) who has not incurred a Termination of Service prior to
the date such forfeiture occurs under the terms of the Savings Plan. The amount
of each such Employer Deferral shall equal 100% of such forfeited amount.

             (ii) Employer Deferrals made on a Member's behalf pursuant to this
Section 3.2(a) for a Plan Year shall be credited to such Member's Employer
Account as of the date the related forfeiture for such Plan Year occurs under
the terms of the Savings Plan.

         (b) As of any date selected by the Employer, the Employer may credit a
Member's Account(s) with Employer Deferrals in such amount, if any, as the
Employer shall determine in its sole discretion. Such credits may be made on
behalf of some Members but not others, and such credits may vary among
individual Members in amount and/or with respect to the Account to which they
are credited.

     3.3 VALUATION OF ACCOUNTS. All amounts credited to an Account shall be
deemed invested in accordance with Article IV on the date such amount is
credited to the Account, and, except as provided in Section 4.2, the balance of
each Account shall reflect the result of the daily pricing of the assets in
which such Account is deemed invested from the time of such crediting until the
time of distribution.

                                       IV.

                           DEEMED INVESTMENT OF FUNDS

     4.1 MEMBER DIRECTIONS.

         (a) Each Member shall designate, in accordance with the procedures
established from time to time by the Committee, the manner in which the amounts
allocated to his Accounts shall be deemed to be invested from among the Funds
made available from time to time for such purpose by the Committee. Such Member
may designate one of such Funds for the deemed investment of all the amounts
allocated to his Accounts or he may split the deemed investment of the amounts
allocated to his Accounts between such Funds in such increments as the Committee
may prescribe. If a Member fails to make a proper designation, then his Accounts
shall be deemed to be invested in the Fund or Funds designated by the Committee
from time to time in a uniform and nondiscriminatory manner. In the event that
during any Plan Year the Committee does not make available Funds for the
investment of the amounts in Members' Accounts, the amounts in each Member's
Accounts shall be credited with earnings at a rate of return set by the
Committee prior to the start of such Plan Year.

         (b) A Member may change his deemed investment designation for future
deferrals to be allocated to his Accounts. Any such change shall be made in
accordance with the procedures established by the Committee, and such changes
may only be made on January 1 and July 1 of each Plan Year.

         (c) A Member may elect to convert his deemed investment designation
with respect to the amounts already allocated to his Accounts. Any such
conversion shall be made in accordance with the procedures established by the
Committee, and such conversions may only be made on January 1 and July 1 of each
Plan Year.

     4.2 CREDITING RATE IN THE ABSENCE OF FUNDS. Notwithstanding the provisions
of Sections 3.3 and 4.1, if for any Plan Year (or portion thereof) the Committee
does not make available Funds for the deemed investment of the amounts in
Members' Accounts, then the amounts in each Member's Accounts shall be credited
with earnings during such period based upon a rate of return set by the
Committee prior to the start of such period. The rate of return set by the
Committee may be fixed for the entire Plan Year (or portion thereof) or it may
vary from time to time based on one or more benchmark rates selected by the
Committee. As of each Valuation Date that occurs during a period for which this
Section 4.2 applies, each Account of a Member shall be increased to reflect an
earnings allocation as described in this Section 4.2 based upon the balance in
such Account as of the next preceding Valuation Date; provided, however, that
the balance of such Account as of the next preceding Valuation Date shall be
reduced by the amount of any withdrawals or distributions made therefrom since
the next preceding Valuation Date.

                DETERMINATION OF VESTED INTEREST AND FORFEITURES

     5.1 DEFERRAL ACCOUNT. A Member shall have a 100% Vested Interest in his
Deferral Account at all times.

     5.2 EMPLOYER ACCOUNT. A Member's Vested Interest in his Employer Account
shall equal such Member's Vested Interest in his "Employer Contribution Account"
under the Savings Plan. Further, a Member who is employed by the Employer
immediately prior to a Change in Control shall have a 100% Vested Interest in
his Employer Account upon the occurrence of such Change in Control; provided,
however, that such accelerated vesting shall not occur if the consummation of
such Change in Control is contingent on using the pooling of interests
accounting methodology and the Committee determines that such accelerated
vesting will prevent the use of such accounting methodology.

     5.3 FORFEITURES. A Member who has a Vested Interest in his Employer Account
that is less than 100% as of the date of his Termination of Service shall
forfeit to the Employer the nonvested portion of such Account as of the date of
such termination. Notwithstanding the preceding provisions of this Article V,
the vested portion of a Member's Account may be forfeited to the Employer under
Sections 6.3, 7.3(c), 7.5(b)(i), and 7.7.

                            IN-SERVICE DISTRIBUTIONS

     6.1 RESTRICTIONS ON IN-SERVICE DISTRIBUTIONS AND LOANS. Except as provided
in Sections 6.2 and 6.3, Members shall not be permitted to make withdrawals from
the Plan prior to incurring a Termination of Service. Members shall not, at any
time, be permitted to borrow from the Trust Fund. Following a Member's
Termination of Service, this Article VI shall not be applicable to the Member
and the amounts credited to such Member's Accounts shall be payable to such
Member in accordance with the provisions of Article VII.

     6.2 EMERGENCY BENEFIT. In the event that the Committee, upon written
petition of a Member, determines in its sole discretion that such Member has
suffered an Unforeseeable Financial Emergency, such Member shall be entitled to
a benefit in an amount not to exceed the lesser of (a) the amount determined by
the Committee as necessary to meet such Member's needs created by the
Unforeseeable Financial Emergency or (b) the then value of such Member's
Deferral Account. Such benefit shall be paid in a single lump sum payment as
soon as administratively practicable after the Committee has made its
determinations with respect to the availability and amount of such benefit. If a
Member's Deferral Account is deemed to be invested in more than one Fund, such
benefit shall be distributed pro rata from each Fund in which such Account is
deemed to be invested.

     6.3 ELECTIVE WITHDRAWAL. A Member may elect at any time, by following the
election procedure prescribed by the Committee, to withdraw as a benefit all or
a portion of his Deferral Account as of any Valuation Date, subject to a
withdrawal penalty of 10% of the amount of any such withdrawal. Upon any such
withdrawal, the withdrawal penalty referred to in the preceding sentence shall
be forfeited to the Employer. Further, upon any such withdrawal, such Member's
participation in the Plan shall terminate and no further Compensation deferrals
shall be made under the Plan on behalf of such Member until the first Election
Date following the date of such withdrawal. If a Member's Deferral Account is
deemed to be invested in more than one Fund, such withdrawal shall be
distributed pro rata from each Fund in which such Account is deemed to be
invested. Notwithstanding the preceding provisions of this Section 6.3, a Member
shall not be entitled to a withdrawal under this Section 6.3 if the Committee
determines, in its sole discretion, that the primary purpose of such withdrawal
is the cessation of Compensation deferrals under the Plan. The Committee shall
consider such factors as it deems appropriate in order to make a determination
pursuant to the preceding sentence, including, without limitation, the amount of
the requested withdrawal, the balance in the Member's Accounts, the Member's
Compensation deferral election then in effect, and the timing of such withdrawal
request.

                              TERMINATION BENEFITS

     7.1 AMOUNT OF BENEFIT. Upon a Member's Termination of Service, the Member,
or, in the event of the death of the Member while employed by the Employer or an
Affiliate, the Member's designated beneficiary, shall be entitled to a benefit
equal in value to the Member's Vested Interest in the balance in his Accounts as
of the Valuation Date next preceding the date the payment of such benefit is to
commence pursuant to Section 7.2.

     7.2 TIME OF PAYMENT. Payment of a Member's benefit under Section 7.1 shall
commence as soon as administratively practicable after the Valuation Date
coincident with or next succeeding the date of the Member's Termination of
Service; provided, however, that, in a written election on the form prescribed
by the Committee, a Member may elect at the time specified in Section 7.3(c) to
defer the commencement of the payment of his benefit in the event of his
Termination of Service prior to his Retirement Date by reason of Disability to
the Valuation Date coincident with or next succeeding the earlier of (a) the
date of such Member's death or (b) such Member's Retirement Date.

     7.3 ALTERNATIVE FORMS OF BENEFIT PAYMENTS.

         (a) A Member's benefit under Section 7.1 shall be paid in the form of a
single lump sum payment if such Member's Termination of Service occurs prior to
his Retirement Date for a reason other than Disability.

         (b) With respect to a Member whose Termination of Service occurs (i)
prior to his Retirement Date by reason of Disability or (ii) on or after his
Retirement Date, such Member shall receive his benefit payments in one of the
following forms elected by such Member in writing on the form prescribed by the
Committee at the time specified in Section 7.3(c):

             (1) A single lump sum payment; or

             (2) Annual installments for a period of five, ten, or fifteen years
     as designated by such Member; provided, however, that in the event of such
     Member's death prior to the end of such period, the remaining balance in
     such Member's Account shall be paid as soon as administratively feasible in
     one lump sum payment to such Member's designated beneficiary as provided in
     Section 7.4. The amount of each annual installment shall be computed by
     dividing the Member's Vested Interest in the unpaid balance in his Accounts
     as of the Valuation Date next preceding the date of payment of such annual
     installment by the number of annual installments remaining.

A separate election shall be made pursuant to this Section 7.3(b) by each Member
with respect to the form of distribution to be made in connection with a
Termination of Service that occurs (A) prior to such Member's Retirement Date by
reason of Disability or (B) on or after such Member's Retirement Date. In the
event such Member fails to timely elect in accordance with Section 7.3(c)

                                     VII-1
<PAGE>   16

the form in which his benefit payments are to be made, such benefit payments
shall be in the form of a single lump sum payment.

         (c) A Member's elections pursuant to Sections 7.2 and 7.3(b) shall be
made on or before the date he first becomes a Member of the Plan.
Notwithstanding the foregoing, subject to the consent of the Committee in its
sole discretion, a Member may, on the form prescribed by the Committee, make one
change to each of his original elections made pursuant to Sections 7.2 and
7.3(b); provided, however, that (i) upon making any such change, the aggregate
balance in such Member's Accounts as of the Valuation Date coincident with or
next succeeding such change shall be reduced by 5% and such amount shall be
forfeited to the Employer and (ii) such change shall not be effective (but the
penalty described in clause (i) of this sentence shall still apply) if such
Member incurs a Termination of Service on or before the date that is thirteen
months after such Member delivers the form implementing such change to the
Committee.

     7.4 DESIGNATION OF BENEFICIARIES.

         (a) Each Member shall have the right to designate the beneficiary or
beneficiaries to receive payment of his benefit in the event of his death. Each
such designation shall be made by executing the beneficiary designation form
prescribed by the Committee and filing same with the Committee. Any such
designation may be changed at any time by execution of a new designation in
accordance with this Section.

         (b) If no such designation is on file with the Committee at the time of
the death of the Member or such designation is not effective for any reason as
determined by the Committee, then the designated beneficiary or beneficiaries to
receive such benefit shall be as follows:

             (i) If a Member leaves a surviving spouse, his benefit shall be
     paid to such surviving spouse;

             (ii) If a Member leaves no surviving spouse, his benefit shall be
     paid to such Member's executor or administrator, or to his heirs at law if
     there is no administration of such Member's estate.

     7.5 ACCELERATED PAY-OUT OF CERTAIN BENEFITS.

         (a) Notwithstanding any provision in Section 7.3(b) to the contrary, if
a Member's benefit payments are to be paid in a form other than entirely in a
single lump sum payment and the aggregate amount to be paid with respect to such
Member in any particular calendar year is less than $50,000, then the Committee
may, in its sole discretion, elect to cause the entire remaining Vested Interest
in the balance in such Member's Accounts to be paid in a single lump sum
payment.

         (b) If a Member incurs a Termination of Service and such Member's
benefit payments are being, or are to be, paid in a form other than entirely in
a single lump sum payment, then:

                                     VII-2
<PAGE>   17

             (i) Such Member may elect at any time, by following the election
     procedure prescribed by the Committee, to receive the Vested Interest in
     the remaining balance in his Accounts (reduced by the 10% penalty described
     in the following sentence) in a single lump sum payment as soon as
     administratively feasible after the date such Member delivers to the
     Committee the form prescribed by the Committee requesting such
     distribution. Upon such a request, the Vested Interest in the aggregate
     balance in such Member's Accounts as of the date of such distribution shall
     be reduced by 10% and such amount shall be forfeited to the Employer; and

             (ii) In the event that the Committee, upon written petition of such
     Member, determines in its sole discretion that such Member has suffered an
     Unforeseeable Financial Emergency, such Member shall be entitled to an
     emergency benefit in an amount and under conditions similar to those
     described in Section 6.2.

     7.6 PAYMENT OF BENEFITS. To the extent the Trust Fund has sufficient
assets, the Trustee shall pay benefits to Members or their beneficiaries, except
to the extent the Employer pays the benefits directly and provides adequate
evidence of such payment to the Trustee. To the extent the Trustee does not or
cannot pay benefits out of the Trust Fund, the benefits shall be paid by the
Employer. Any benefit payments made to a Member or for his benefit pursuant to
any provision of the Plan shall be debited to such Member's Accounts. All
benefit payments shall be made in cash to the fullest extent practicable.

     7.7 UNCLAIMED BENEFITS. In the case of a benefit payable on behalf of a
Member, if the Committee is unable to locate the Member or beneficiary to whom
such benefit is payable, upon the Committee's determination thereof, such
benefit shall be forfeited to the Employer. Notwithstanding the foregoing, if
subsequent to any such forfeiture the Member or beneficiary to whom such benefit
is payable makes a valid claim for such benefit, such forfeited benefit (without
any adjustment for earnings or loss after the time of such forfeiture) shall be
restored to the Plan by the Employer and paid in accordance with the Plan.

                           ADMINISTRATION OF THE PLAN

     8.1. APPOINTMENT OF COMMITTEE. The general administration of the Plan shall
be vested in the Committee which shall be appointed by the Compensation
Committee and shall consist of one or more persons. Any individual, whether or
not an employee of the Employer, is eligible to become a member of the
Committee.

     8.2. TERM, VACANCIES, RESIGNATION, AND REMOVAL. Each member of the
Committee shall serve until he resigns, dies, or is removed by the Compensation
Committee. At any time during his term of office, a member of the Committee may
resign by giving written notice to the Compensation Committee and the Committee,
such resignation to become effective upon the appointment of a substitute member
or, if earlier, the lapse of thirty days after such notice is given as herein
provided. At any time during his term of office, and for any reason, a member of
the Committee may be removed by the Compensation Committee with or without
cause, and the Compensation Committee may in its discretion fill any vacancy
that may result therefrom. Any member of the Committee who is an employee of the
Employer or any Affiliate shall automatically cease to be a member of the
Committee as of the date he ceases to be employed by the Employer and all
Affiliates.

     8.3. SELF-INTEREST OF MEMBERS. No member of the Committee shall have any
right to vote or decide upon any matter relating solely to himself under the
Plan or to vote in any case in which his individual right to claim any benefit
under the Plan is particularly involved. In any case in which a Committee member
is so disqualified to act and the remaining members cannot agree, the
Compensation Committee shall appoint a temporary substitute member to exercise
all the powers of the disqualified member concerning the matter in which he is
disqualified.

     8.4. COMMITTEE POWERS AND DUTIES. The Committee shall supervise the
administration and enforcement of the Plan according to the terms and provisions
hereof and shall have all powers necessary to accomplish these purposes,
including, but not by way of limitation, the right, power, and authority:

         (a) To make rules, regulations, and bylaws for the administration of
the Plan that are not inconsistent with the terms and provisions hereof, and to
enforce the terms of the Plan and the rules and regulations promulgated
thereunder by the Committee;

         (b) To construe in its discretion all terms, provisions, conditions,
and limitations of the Plan;

         (c) To correct any defect or to supply any omission or to reconcile any
inconsistency that may appear in the Plan in such manner and to such extent as
it shall deem in its discretion expedient to effectuate the purposes of the
Plan;

                                     VIII-1
<PAGE>   19

         (d) To employ and compensate such accountants, attorneys, investment
advisors, and other agents, employees, and independent contractors as the
Committee may deem necessary or advisable for the proper and efficient
administration of the Plan;

         (e) To determine in its discretion all questions relating to
eligibility;

         (f) To determine whether and when a Member has incurred a Termination
of Service, and the reason for such termination;

         (g) To make a determination in its discretion as to the right of any
person to a benefit under the Plan and to prescribe procedures to be followed by
distributees in obtaining benefits hereunder;

         (h) To receive and review reports from the Trustee as to the financial
condition of the Trust Fund, including its receipts and disbursements; and

         (i) To establish or designate Funds as investment options as provided
in Section 4.1.

     8.5. CLAIMS REVIEW. In any case in which a claim for Plan benefits of a
Member or beneficiary is denied or modified, the Committee shall furnish written
notice to the claimant within 90 days (or within 180 days if additional
information requested by the Committee necessitates an extension of the 90-day
period), which notice shall:

         (a) State the specific reason or reasons for the denial or
modification;

         (b) Provide specific reference to pertinent Plan provisions on which
the denial or modification is based;

         (c) Provide a description of any additional material or information
necessary for the Member, his beneficiary, or representative to perfect the
claim and an explanation of why such material or information is necessary; and

         (d) Explain the Plan's claim review procedure as contained herein.

In the event a claim for Plan benefits is denied or modified, if the Member, his
beneficiary, or a representative of such Member or beneficiary desires to have
such denial or modification reviewed, he must, within 60 days following receipt
of the notice of such denial or modification, submit a written request for
review by the Committee of its initial decision. In connection with such
request, the Member, his beneficiary, or the representative of such Member or
beneficiary may review any pertinent documents upon which such denial or
modification was based and may submit issues and comments in writing. Within 60
days following such request for review the Committee shall, after providing a
full and fair review, render its final decision in writing to the Member, his
beneficiary, or the representative of such Member or beneficiary stating
specific reasons for such decision and making specific references to pertinent
Plan provisions upon which the decision is based. If special

                                     VIII-2
<PAGE>   20

circumstances require an extension of such 60-day period, the Committee's
decision shall be rendered as soon as possible, but not later than 120 days
after receipt of the request for review. If an extension of time for review is
required, written notice of the extension shall be furnished to the Member,
beneficiary, or the representative of such Member or beneficiary prior to the
commencement of the extension period.

     8.6. MANDATORY ARBITRATION. If the Member, his beneficiary, or a
representative of such Member or beneficiary is not satisfied with the final
decision of the Committee pursuant to the Plan's claims review procedure, such
Member, his beneficiary, or a representative of such Member or beneficiary may,
within 180 days of receipt of the written final decision of the Committee,
request by written notice to the Committee, that his claim be submitted to
arbitration pursuant to the arbitration procedures then in effect as adopted by
the Committee. Such arbitration shall be the sole and exclusive procedure
available to the Member, his beneficiary, or a representative of such Member or
his beneficiary for review of a final decision of the Committee. In reviewing
the decision of the Committee, the arbitrator shall use the standard of review
which would be used by a Federal court in reviewing such decision under the
provisions of ERISA. The Member, his beneficiary, or a representative of such
Member or beneficiary and the Plan shall share equally the cost of such
arbitration. The arbitrator's decision shall be final and legally binding on
both parties. This Section shall be governed by the provisions of the Federal
Arbitration Act.

     8.7. EMPLOYER TO SUPPLY INFORMATION. The Employer shall supply full and
timely information to the Committee, including, but not limited to, information
relating to each Member's Compensation, age, retirement, death, or other cause
of Termination of Service and such other pertinent facts as the Committee may
require. The Employer shall advise the Trustee of such of the foregoing facts as
are deemed necessary for the Trustee to carry out the Trustee's duties under the
Plan and the Trust Agreement. When making a determination in connection with the
Plan, the Committee shall be entitled to rely upon the aforesaid information
furnished by the Employer.

     8.8. INDEMNITY. To the extent permitted by applicable law, the Company
shall indemnify and save harmless each member of the Committee and the
Compensation Committee against any and all expenses, liabilities and claims
(including legal fees incurred to defend against such liabilities and claims)
arising out of their discharge in good faith of responsibilities under or
incident to the Plan. Expenses and liabilities arising out of willful misconduct
shall not be covered under this indemnity. This indemnity shall not preclude
such further indemnities as may be available under insurance purchased by the
Company or provided by the Company under any bylaw, agreement, vote of
stockholders or disinterested directors or otherwise, as such indemnities are
permitted under applicable law.

     8.9. CHANGE IN CONTROL. Notwithstanding any provision in the Plan to the
contrary, upon the occurrence of a Change in Control, the Committee's powers and
duties under the Plan shall cease to the extent, if any, such powers and duties
are vested in the Trustee under the terms of the Trust Agreement.

                             ADMINISTRATION OF FUNDS

     9.1. PAYMENT OF EXPENSES. All expenses incident to the administration of
the Plan and Trust, including but not limited to, legal, accounting, Trustee
fees, and expenses of the Committee, may be paid by the Employer and, if not
paid by the Employer, shall be paid by the Trustee from the Trust Fund, if any.

     9.2. TRUST FUND PROPERTY. All income, profits, recoveries, contributions,
forfeitures and any and all moneys, securities and properties of any kind at any
time received or held by the Trustee, if any, shall be held for investment
purposes as a commingled Trust Fund pursuant to the terms of the Trust
Agreement. The Committee shall maintain one or more Accounts in the name of each
Member, but the maintenance of an Account designated as the Account of a Member
shall not mean that such Member shall have a greater or lesser interest than
that due him by operation of the Plan and shall not be considered as segregating
any funds or property from any other funds or property contained in the
commingled fund. No Member shall have any title to any specific asset in the
Trust Fund, if any.

                               NATURE OF THE PLAN

     The Employer intends and desires by the adoption of the Plan to recognize
the value to the Employer of the past and present services of employees covered
by the Plan and to encourage and assure their continued service with the
Employer by making more adequate provision for their future retirement security.
The establishment of the Plan is made necessary by certain benefit limitations
which are imposed on the Savings Plan by ERISA and by the Code. The Plan is
intended to constitute an unfunded, unsecured plan of deferred compensation for
a select group of management or highly compensated employees of the Employer.
Plan benefits herein provided are a contractual obligation of the Employer which
shall be paid out of the Employer's general assets. Nevertheless, subject to the
terms hereof and of the Trust Agreement, the Employer may transfer money or
other property to the Trustee to provide Plan benefits hereunder, and the
Trustee shall pay Plan benefits to Members and their beneficiaries out of the
Trust Fund. To the extent that Employer transfers assets to the Trustee pursuant
to the Trust Agreement, the Committee may, but need not, establish procedures
for the Trustees to invest the Trust Fund in accordance with each Member's
designated deemed investments pursuant to Section 4.1 respecting the portion of
the Trust Fund assets equal to such Member's Accounts.

     The Compensation Committee, in its sole discretion, may establish the Trust
and direct the Employer to enter into the Trust Agreement. In such event, the
Employer shall remain the owner of all assets in the Trust Fund and the assets
shall be subject to the claims of the Employer's creditors if the Employer ever
becomes insolvent. For purposes hereof, the Employer shall be considered
"insolvent" if (a) the Employer is unable to pay its debts as such debts become
due or (b) the Employer is subject to a pending proceeding as a debtor under the
United Sates Bankruptcy Code (or any successor federal statute). The chief
executive officer of the Employer and its board of directors shall have the duty
to inform the Trustee in writing if the Employer becomes insolvent. Such notice
given under the preceding sentence by any party shall satisfy all of the
parties' duty to give notice. When so informed, the Trustee shall suspend
payments to the Members and hold the assets for the benefit of the Employer's
general creditors. If the Trustee receives a written allegation that the
Employer is insolvent, the Trustee shall suspend payments to the Members and
hold the Trust Fund for the benefit of the Employer's general creditors, and
shall determine in the manner specified in the Trust Agreement whether the
Employer is insolvent. If the Trustee determines that the Employer is not
insolvent, the Trustee shall resume payments to the Members. No Member or
beneficiary shall have any preferred claim to, or any beneficial ownership
interest in, any assets of the Trust Fund, and, upon commencement of
participation in the Plan, each Member shall have agreed to waive his priority
credit position, if any, under applicable state law with respect to the assets
of the Trust Fund.

                                  MISCELLANEOUS

     11.1 NO CONTRACT OF EMPLOYMENT. The adoption and maintenance of the Plan
shall not be deemed to be a contract between the Employer and any person or to
be consideration for the employment of any person. Nothing herein contained
shall be deemed to (a) give any person the right to be retained in the employ of
the Employer, (b) restrict the right of the Employer to discharge any person at
any time, (c) give the Employer the right to require any person to remain in the
employ of the Employer, or (d) restrict any person's right to terminate his
employment at any time.

     11.2 ALIENATION OF INTEREST FORBIDDEN. The interest of a Member or his
beneficiary or beneficiaries hereunder may not be sold, transferred, assigned,
or encumbered in any manner, either voluntarily or involuntarily, and any
attempt so to anticipate, alienate, sell, transfer, assign, pledge, encumber, or
charge the same shall be null and void; neither shall the benefits hereunder be
liable for or subject to the debts, contracts, liabilities, engagements or torts
of any person to whom such benefits or funds are payable, nor shall they be an
asset in bankruptcy or subject to garnishment, attachment or other legal or
equitable proceedings.

     11.3 WITHHOLDING. All Compensation deferrals and Employer Deferrals and
payments provided for hereunder shall be subject to applicable withholding and
other deductions as shall be required of the Employer under any applicable
local, state or federal law.

     11.4 AMENDMENT AND TERMINATION. The Compensation Committee may from time to
time, in its discretion, amend, in whole or in part, any or all of the
provisions of the Plan; provided, however, that no amendment may be made that
would impair the rights of a Member with respect to amounts already allocated to
his Accounts. The Compensation Committee may terminate the Plan at any time. In
the event that the Plan is terminated, the Vested Interest in the balance in a
Member's Accounts shall be paid to such Member or his designated beneficiary in
the manner specified by the Compensation Committee, which may include the
payment of a single lump sum payment in full satisfaction of all of such
Member's or beneficiary's benefits hereunder.

     11.5 SEVERABILITY. If any provision of this Plan shall be held illegal or
invalid for any reason, said illegality or invalidity shall not affect the
remaining provisions hereof; instead, each provision shall be fully severable
and the Plan shall be construed and enforced as if said illegal or invalid
provision had never been included herein.

     11.6 GUARANTY. Notwithstanding any provisions of the Plan to the contrary,
in the event any Employer fails to make payment of the benefits due under the
Plan on behalf of its Members, whether directly or through the Trust, the
Company shall be liable for and shall make payment of such benefits due as a
guarantor of such entity's obligations hereunder. The guaranty obligations
provided herein shall be satisfied directly and not through the Trust.

     11.7 GOVERNING LAWS. All provisions of the Plan shall be construed in
accordance with the laws of Texas except to the extent preempted by federal law.
