         percent (100%) of the cash proceeds received by the Parent from the
         exercise of stock options after January 1, 2003, (d) the Parent may, in
         addition to its rights granted pursuant to clause (c) above, purchase
         shares of its capital stock in an aggregate amount not to exceed
         $100,000,000, and (e) the Parent may, in addition to its rights granted
         pursuant to clauses (c) and (d) above, purchase shares of its capital
         stock in an amount not to exceed fifty percent (50%) of the Net
         Financing Proceeds from a Permitted Debt Offering which is in the form
         of convertible subordinated notes, provided that an amount equal to
         fifty percent (50%) of the Net Financing Proceeds from such Permitted
         Debt Offering is simultaneously applied PRO RATA to reduce outstanding
         Loans hereunder. Any Term Loan Lender may decline to accept any
         payments due to such Term Loan Lender pursuant to clause (e) above in
         which case such declined payments shall be used to repay the Revolving
         Credit Loans (but not reduce the Total Revolving Credit Commitment) on
         a PRO RATA basis in accordance with each Lender's Commitment
         Percentage. In addition, the Borrowers shall not effect or permit any
         change in or amendment to any document or instrument pertaining to the
         terms of any Borrower's (other than the Parent's) capital stock.
         Notwithstanding the foregoing, no Borrower shall make any Distribution
         and/or purchase any shares of its capital stock under this ss.8.6 if
         (i) a Default or Event of Default exists or would be created by the
         making of such Distribution or by the purchase of such capital stock,
         as the case may be, or (ii) with respect to Distributions and/or
         purchases of shares of its capital stock made under clauses (c) through
         (e) above, the Leverage Ratio taking into account such Distribution
         and/or such purchase would exceed 3.75 to 1.00."

         SS.4. AMENDMENTS TO SECTION 8.11 OF THE CREDIT AGREEMENT. Section 8.11
of the Credit Agreement is hereby amended by deleting such Section in its
entirety and substituting the following new Section 8.11 in proper numerical
order in lieu thereof:

                  "SS.8.11 SUBORDINATED DEBT. No Borrower will amend, supplement
         or otherwise modify the terms of any of the Subordinated Debt or any of
         the documents evidencing such Subordinated Debt or prepay, redeem or
         purchase any of the Subordinated Debt without the consent of the
         Required Lenders; provided, however, so long as no Default or Event of
         Default has occurred and is continuing, or would be created thereby,
         the Borrowers shall be permitted to (i) make regularly scheduled

                                       -2-

         whole or in part, with proceeds of Subordinated Debt, and (v) amend,
         supplement or otherwise modify the 2022 Convertible Subordinated Notes
         and the 2022 Notes Indenture or replace the 2022 Convertible
         Subordinated Notes with proceeds of Subordinated Debt, provided, that
         any such amendment, supplement or modification thereto or replacement
         thereof shall (a) provide for a maturity date which extends beyond the
         Revolving Credit Maturity Date and the Term Loan Maturity Date and (b)
         otherwise not change, alter or modify any material terms of such
         Convertible Subordinated Notes in any manner which adversely affects
         the Lenders."

                     NONQUALIFIED DEFERRED COMPENSATION PLAN
                             Effective July 1, 2004

                                     PURPOSE
                                     -------

         The purpose of this Plan is to provide specified benefits to a select
group of management or highly compensated Employees and Directors who contribute
materially to the continued growth, development and future business success of
Waste Connections, Inc., a Delaware corporation, and its subsidiaries, if any,
that sponsor this Plan. This Plan shall be unfunded for tax purposes and for
purposes of Title I of ERISA.

                                    ARTICLE 1
                                   DEFINITIONS
                                   -----------

         For the purposes of this Plan, unless otherwise clearly apparent from
the context, the following phrases or terms shall have the following indicated
meanings:

1.1      "Account Balance" shall mean, with respect to a Participant, an entry
         on the records of the Employer equal to the sum of (i) the Deferral
         Account balance, (ii) the Company Contribution Account balance, and
         (iii) the Company Restoration Matching Account balance. The Account
         Balance shall be a bookkeeping entry only and shall be utilized solely
         as a device for the measurement and determination of the amounts to be
         paid to a Participant, or his or her designated Beneficiary, pursuant
         to this Plan.

1.2      "Annual Deferral Amount" shall mean that portion of a Participant's
         Base Salary, Bonus, Commissions, Director Fees and LTIP Amounts that a
         Participant defers in accordance with Article 3 for any one Plan Year,
         without regard to whether such amounts are withheld and credited during
         such Plan Year. In the event of a Participant's Retirement, Disability,
         death or Termination of Employment prior to the end of a Plan Year,
         such year's Annual Deferral Amount shall be the actual amount withheld
         prior to such event.

1.3      "Annual Installment Method" shall be an annual installment payment over
         the number of years selected by the Participant in accordance with this
         Plan, calculated as follows: (i) for the first annual installment, the
         Participant's vested Account Balance shall be calculated as of the
         close of business on or around the last day of the six-month period
         immediately following the date on which the Participant Retires, as
         determined by the Committee in its sole discretion, and (ii) for
         remaining annual installments, the Participant's vested Account Balance
         shall be calculated on every anniversary of such calculation date, as
         applicable. Each annual installment shall be calculated by multiplying
         this balance by a fraction, the numerator of which is one and the
         denominator of which is the remaining number of annual payments due the
         Participant. By way of example, if the Participant elects a ten (10)
         year Annual Installment Method for the Retirement Benefit, the first
         payment shall be 1/10 of the vested Account Balance, calculated as
         described in this definition. The following year, the payment shall be
         1/9 of the vested Account Balance, calculated as described in this
         definition.

1.4      "Base Salary" shall mean the annual cash compensation relating to
         services performed during any calendar year, excluding distributions
         from nonqualified deferred compensation plans, bonuses, commissions,

         incentive payments, non-monetary awards, director fees and other fees,
         and automobile and other allowances paid to a Participant for
         employment services rendered (whether or not such allowances are
         included in the Employee's gross income). Base Salary shall be
         calculated before reduction for compensation voluntarily deferred or
         contributed by the Participant pursuant to all qualified or
         nonqualified plans of any Employer and shall be calculated to include
         amounts not otherwise included in the Participant's gross income under
         Code Sections 125, 402(e)(3), 402(h), or 403(b) pursuant to plans
         established by any Employer; provided, however, that all such amounts
         will be included in compensation only to the extent that had there been
         no such plan, the amount would have been payable in cash to the
         Employee.

1.5      "Beneficiary" shall mean one or more persons, trusts, estates or other
         entities, designated in accordance with Article 10, that are entitled
         to receive benefits under this Plan upon the death of a Participant.

1.6      "Beneficiary Designation Form" shall mean the form established from
         time to time by the Committee that a Participant completes, signs and
         returns to the Committee to designate one or more Beneficiaries.

1.7      "Benefit Distribution Date" shall mean the date that triggers
         distribution of a Participant's vested Account Balance. A Participant's
         Benefit Distribution Date shall be determined upon the occurrence of
         any one of the following:

         (a)   If the Participant Retires, his or her Benefit Distribution Date
               shall be the last day of the six-month period immediately
               following the date on which the Participant Retires; or

         (b)   If the Participant experiences a Termination of Employment, his
               or her Benefit Distribution Date shall be the last day of the
               six-month period immediately following the date on which the
               Participant experiences a Termination of Employment; or

         (c)   The date on which the Committee is provided with proof that is
               satisfactory to the Committee of the Participant's death, if the
               Participant dies prior to the complete distribution of his or her
               vested Account Balance; or

         (d)   The date on which the Participant becomes Disabled; or

         (e)   The date on which the Company experiences a Change in Control, as
               determined by the Committee in its sole discretion, if (i) the
               Participant has elected to receive a Change in Control Benefit,
               as set forth in Section 5.2 below, and (ii) if a Change in
               Control occurs prior to the Participant's Termination of
               Employment, Retirement, death or Disability.

1.8      "Board" shall mean the board of directors of the Company.

1.9      "Bonus" shall mean any compensation, in addition to Base Salary,
         Commissions and LTIP Amounts, earned by a Participant for services
         rendered during a Plan Year, under any Employer's annual bonus and cash
         incentive plans.

               to time such other enrollment requirements as it determines in
               its sole discretion are necessary.

         (c)   Each Employee or Director who is eligible to participate in the
               Plan shall commence participation in the Plan on the date that
               the Committee determines, in its sole discretion, that the
               Employee or Director has met all enrollment requirements set
               forth in this Plan and required by the Committee, including
               returning all required documents to the Committee within the
               specified time period. Notwithstanding the foregoing, the
               Committee shall process such Participant's deferral election as
               soon as administratively practicable after such deferral election
               is submitted to and accepted by the Committee.

         (d)   If an Employee or a Director fails to meet all requirements
               contained in this Section 2.2 within the period required, that
               Employee or Director shall not be eligible to participate in the
               Plan during such Plan Year.

2.3      TERMINATION OF A PARTICIPANT'S ELIGIBILITY. If the Committee determines
         that a Participant is no longer eligible to participate in the Plan,
         the Committee shall have the right, in its sole discretion, to (i)
         terminate any deferral election the Participant has made for the
         remainder of the Plan Year in which the Participant's membership status
         changes, (ii) prevent the Participant from making future deferral
         elections, and/or (iii) take further action that the Committee deems
         appropriate. Notwithstanding the foregoing, in the event of a
         Termination of the Plan, the termination of the affected Participants'
         eligibility for participation in the Plan shall not be governed by this
         Section 2.3, but rather shall be governed by Section 1.41 and Section
         11.1.

         (B)   SHORT PLAN YEAR. Notwithstanding the foregoing, if a Participant
               first becomes a Participant after the first day of a Plan Year,
               the maximum Annual Deferral Amount shall be limited to the amount
               of compensation not yet earned by the Participant as of the date
               the Participant submits a Plan Agreement and Election Form to the
               Committee for acceptance.

3.3      ELECTION TO DEFER; EFFECT OF ELECTION FORM.

         (A)   FIRST PLAN YEAR. In connection with a Participant's commencement
               of participation in the Plan, the Participant shall make an
               irrevocable deferral election for the Plan Year in which the
               Participant commences participation in the Plan, along with such
               other elections as the Committee deems necessary or desirable
               under the Plan. For these elections to be valid, the Election
               Form must be completed and signed by the Participant, timely
               delivered to the Committee (in accordance with Section 2.2 above)
               and accepted by the Committee.

         (B)   SUBSEQUENT PLAN YEARS. For each succeeding Plan Year, an

               elections as the Committee deems necessary or desirable under the
               Plan, shall be made by timely delivering a new Election Form to
               the Committee, in accordance with its rules and procedures,
               before the end of the Plan Year preceding the Plan Year for which
               the election is made. If no such Election Form is timely

               zero for that Plan Year.

         Year, the Base Salary portion of the Annual Deferral Amount shall be
         withheld from each regularly scheduled Base Salary payroll in equal
         amounts, as adjusted from time to time for increases and decreases in
         Base Salary. The Bonus, Commissions, LTIP Amounts and/or Director Fees
         portion of the Annual Deferral Amount shall be withheld at the time the
         Bonus, Commissions, LTIP Amounts or Director Fees are or otherwise
         would be paid to the Participant, whether or not this occurs during the
         Plan Year itself. Annual Deferral Amounts shall be credited to a

3.5      COMPANY CONTRIBUTION AMOUNT.

         (a)   For each Plan Year, an Employer may be required to credit amounts
               to a Participant's Company Contribution Account in accordance
               with employment or other agreements entered into between the
               Participant and the Employer. Such amounts shall be credited on
               the date or dates prescribed by such agreements.

         (b)   For each Plan Year, an Employer, in its sole discretion, may, but
               is not required to, credit any amount it desires to any
               Participant's Company Contribution Account under this Plan, which
               amount shall be for that Participant the Company Contribution
               Amount for that Plan Year. The amount so credited to a
               Participant may be smaller or larger than the amount credited to
               any other Participant, and the amount credited to any Participant
               for a Plan Year may be zero, even though one or more other
               Participants receive a Company Contribution Amount for that Plan
               Year. The Company Contribution Amount described in this Section
               3.5(b), if any, shall be credited on a date or dates to be
               determined by the Committee, in its sole discretion.

3.6      COMPANY RESTORATION MATCHING AMOUNT. A Participant's Company
         Restoration Matching Amount for any Plan Year shall be an amount
         determined by the Committee, in its sole discretion, to make up for
         certain limits applicable to the 401(k) Plan or other qualified plan
         for such Plan Year, as identified by the Committee, or for such other
         purposes as determined by the Committee in its sole discretion. The
         amount so credited to a Participant under this Plan for any Plan Year
         (i) may be smaller or larger than the amount credited to any other
         Participant, and (ii) may differ from the amount credited to such
         Participant in the preceding Plan Year. The Participant's Company
         Restoration Matching Account, if any, shall be credited on a date or
         dates to be determined by the Committee, in its sole discretion.

3.7      CREDITING OF AMOUNTS AFTER BENEFIT DISTRIBUTION. Notwithstanding any
         provision in this Plan to the contrary, should the complete
         distribution of a Participant's vested Account Balance occur prior to
         the date on which any portion of (i) the Annual Deferral Amount that a
         Participant has elected to defer in accordance with Section 3.3, (ii)
         the Company Contribution Amount, or (iii) the Company Restoration
         Matching Amount, would otherwise be credited to the Participant's
         Account Balance, such amounts shall not be credited to the
         Participant's Account Balance, but shall be paid to the Participant in
         a manner determined by the Committee, in its sole discretion.

3.8      VESTING. A Participant shall at all times be 100% vested in his or her
         Deferral Account, Company Contribution Account and Company Restoration
         Matching Account.

3.9      CREDITING/DEBITING OF ACCOUNT BALANCES. In accordance with, and subject
         to, the rules and procedures that are established from time to time by
         the Committee, in its sole discretion, amounts shall be credited or
         debited to a Participant's Account Balance in accordance with the
         following rules:

         (a)   MEASUREMENT FUNDS. The Participant may elect one or more of the
               measurement funds selected by the Committee, in its sole
               discretion, which are based on certain mutual funds (the
               "Measurement Funds"), for the purpose of crediting or debiting
               additional amounts to his or her Account Balance. As necessary,
               the Committee may, in its sole discretion, discontinue,
               substitute or add a Measurement Fund. Each such action will take
               effect as of the first day of the first calendar quarter that
               begins at least thirty (30) days after the day on which the

================================================================================

               Committee gives Participants advance written notice of such
               change, or if necessary to comply with applicable tax law,
               including but not limited to guidance issued after the effective
               date of this Plan, such other date designated by the Committee,
               in its sole discretion.

         (b)   ELECTION OF MEASUREMENT FUNDS. A Participant, in connection with
               his or her initial deferral election in accordance with Section
               3.3(a) above, shall elect, on the Election Form, one or more
               Measurement Fund(s) (as described in Section 3.9(a) above) to be
               used to determine the amounts to be credited or debited to his or
               her Account Balance. If a Participant does not elect any of the
               Measurement Funds as described in the previous sentence, the
               Participant's Account Balance shall automatically be allocated
               into the lowest-risk Measurement Fund, as determined by the
               Committee, in its sole discretion. The Participant may (but is
               not required to) elect, by submitting an Election Form to the
               Committee that is accepted by the Committee, to add or delete one
               or more Measurement Fund(s) to be used to determine the amounts
               to be credited or debited to his or her Account Balance, or to
               change the portion of his or her Account Balance allocated to
               each previously or newly elected Measurement Fund. If an election
               is made in accordance with the previous sentence, it shall apply
               as of the first business day deemed reasonably practicable by the
               Committee, in its sole discretion, and shall continue thereafter
               for each subsequent day in which the Participant participates in
               the Plan, unless changed in accordance with the previous
               sentence.

         (c)   PROPORTIONATE ALLOCATION. In making any election described in
               Section 3.9(b) above, the Participant shall specify on the
               Election Form, in increments of one percent (1%), the percentage
               of his or her Account Balance or Measurement Fund, as applicable,
               to be allocated/reallocated.

         (d)   CREDITING OR DEBITING METHOD. The performance of each Measurement
               Fund (either positive or negative) will be determined by the
               Committee, in its sole discretion, on a daily basis based on the
               manner in which such Participant's Account Balance has been
               hypothetically allocated among the Measurement Funds by the
               Participant.

         (e)   NO ACTUAL INVESTMENT. Notwithstanding any other provision of this
               Plan that may be interpreted to the contrary, the Measurement
               Funds are to be used for measurement purposes only, and a
               Participant's election of any such Measurement Fund, the
               allocation of his or her Account Balance thereto, the calculation
               of additional amounts and the crediting or debiting of such
               amounts to a Participant's Account Balance shall not be
               considered or construed in any manner as an actual investment of
               his or her Account Balance in any such Measurement Fund. In the
               event that the Company or the Trustee (as that term is defined in
               the Trust), in its own discretion, decides to invest funds in any
               or all of the investments on which the Measurement Funds are
               based, no Participant shall have any rights in or to such
               investments themselves. Without limiting the foregoing, a
               Participant's Account Balance shall at all times be a bookkeeping
               entry only and shall not represent any investment made on his or
               her behalf by the Company or the Trust; the Participant shall at
               all times remain an unsecured creditor of the Company.

         Restoration Matching Amount. The Scheduled Distribution shall be a lump
         sum payment in an amount that is equal to the portion of the Annual
         Deferral Amount, the vested portion of the Company Contribution Amount
         and the vested portion of the Company Restoration Matching Amount that
         the Participant elected to have distributed as a Scheduled
         Distribution, plus amounts credited or debited in the manner provided
         in Section 3.9 above on that amount, calculated as of the close of
         business on or around the date on which the Scheduled Distribution
         becomes payable, as determined by the Committee in its sole discretion.
         Subject to the other terms and conditions of this Plan, each Scheduled
         Distribution elected shall be paid out during a sixty (60) day period
         commencing immediately after the first day of any Plan Year designated
         by the Participant. The Plan Year designated by the Participant must be
         at least three (3) Plan Years after the end of the Plan Year to which
         the Participant's deferral election described in Section 3.3 relates.

         Matching Amounts that are earned and/or contributed in the Plan Year
         commencing January 1, 2004, the Scheduled Distribution would become
         payable during a sixty (60) day period commencing January 1, 2008.
         Notwithstanding the language set forth above, the Committee shall, in
         its sole discretion, adjust the amount distributable as a Scheduled
         Distribution if any portion of the Company Contribution Amount or
         Company Restoration Matching Amount is unvested on the Scheduled
         Distribution Date.

4.2      POSTPONING SCHEDULED DISTRIBUTIONS. A Participant may elect to postpone
         any lump sum distribution described in Section 4.1 above, and have such
         amount paid out during a sixty (60) day period commencing immediately
         after an allowable alternative distribution date designated by the
         Participant in accordance with this Section 4.2. In order to make this
         election, the Participant must submit a new Scheduled Distribution
         Election Form to the Committee in accordance with the following
         criteria:

         (a)   Such Scheduled Distribution Election Form must be submitted to
               and accepted by the Committee at least twelve (12) months prior
               to the Participant's previously designated Scheduled Distribution
               Date; and

         (b)   The new Scheduled Distribution Date selected by the Participant
               must be the first day of a Plan Year, and must be at least five
               (5) years after the previously designated Scheduled Distribution
               Date.

         (c)   The election of the new Scheduled Distribution Date shall have no
               effect until at least twelve (12) months after the date on which
               the election is made.

4.3      OTHER BENEFITS TAKE PRECEDENCE OVER SCHEDULED DISTRIBUTIONS. Should a
         Benefit Distribution Date occur that triggers a benefit under Articles
         5, 6, 7, 8, or 9, any Annual Deferral Amount, Company Contribution
         Amount and/or Company Restoration Matching Amount, plus amounts
         credited or debited thereon, that are subject to a Scheduled
         Distribution election under Section 4.1 shall not be paid in accordance
         with Section 4.1, but shall be paid in accordance with the other
         applicable Article.

4.4      WITHDRAWAL PAYOUT/SUSPENSIONS FOR UNFORESEEABLE FINANCIAL EMERGENCIES.

         (a)   If the Participant experiences an Unforeseeable Financial
               Emergency, the Participant may petition the Committee to suspend
               deferrals of Base Salary, Bonus, Commissions, Director Fees, and
               LTIP Amounts to the extent deemed necessary by the Committee to
               satisfy the Unforeseeable Financial Emergency, plus amounts
               reasonably necessary to pay taxes reasonably anticipated as a
               result of the distribution. If suspension of deferrals is not
               sufficient to satisfy the Participant's Unforeseeable Financial
               Emergency, or if suspension of deferrals is not required under
               applicable tax law, the Participant may further petition the
               Committee to receive a partial or full payout from the Plan. The
               Participant shall only receive a payout from the Plan to the
               extent such payout is deemed necessary by the Committee to
               satisfy the Participant's Unforeseeable Financial Emergency.

         (b)   The payout shall not exceed the lesser of (i) the Participant's
               vested Account Balance, calculated as of the close of business on
               or around the date on which the amount becomes payable, as

               determined by the Committee in its sole discretion, or (ii) the
               amount necessary to satisfy the Unforeseeable Financial
               Emergency, plus amounts reasonably necessary to pay taxes
               reasonably anticipated as a result of the distribution.
               Notwithstanding the foregoing, a Participant may not receive a
               payout from the Plan to the extent that the Unforeseeable
               Financial Emergency is or may be relieved (A) through
               reimbursement or compensation by insurance or otherwise, (B) by
               liquidation of the Participant's assets, to the extent the
               liquidation of such assets would not itself cause severe
               financial hardship or (C) by suspension of deferrals under this
               Plan, if the Committee, in its sole discretion, determines that
               suspension is required by applicable tax law.

         (c)   If the Committee, in its sole discretion, approves a
               Participant's petition for suspension, the Participant's
               deferrals under this Plan shall be suspended as of the date of
               such approval. If the Committee, in its sole discretion, approves
               a Participant's petition for suspension and payout, the
               Participant's deferrals under this Plan shall be suspended as of
               the date of such approval and the Participant shall receive a
               payout from the Plan within sixty (60) days of the date of such
               approval.

         (d)   Notwithstanding the foregoing, the Committee shall interpret all
               provisions relating to suspension and/or payout under this
               Section 4.4 in a manner that is consistent with applicable tax
               law, including but not limited to guidance issued after the
               effective date of this Plan.

         Control Benefit, which shall be equal to the Participant's vested
         Account Balance, calculated as of the close of business on or around
         the Participant's Benefit Distribution Date, as selected by the
         Committee in its sole discretion.

5.2      PAYMENT OF CHANGE IN CONTROL BENEFIT. A Participant, in connection with
         his or her commencement of participation in the Plan, shall irrevocably
         elect on an Election Form whether to (i) receive a Change in Control
         Benefit, or (ii) have his or her Account Balance remain in the Plan
         upon the occurrence of a Change in Control and to have his or her
         Account Balance remain subject to the terms and conditions of the Plan.
         If a Participant does not make any election with respect to the payment
         of the Change in Control Benefit, then such Participant shall be deemed
         to have elected to receive a Change in Control Benefit upon the
         occurrence of a Change in Control. The Change in Control Benefit, if
         any, shall be paid to the Participant in a lump sum no later than sixty
         (60) days after the Participant's Benefit Distribution Date.
         Notwithstanding the foregoing, the Committee shall interpret all
         provisions in this Plan relating to a Change in Control Benefit in a
         manner that is consistent with applicable tax law, including but not
         limited to guidance issued after the effective date of this Plan.

                             BENEFICIARY DESIGNATION
                             -----------------------

10.1     BENEFICIARY. Each Participant shall have the right, at any time, to
         designate his or her Beneficiary(ies) (both primary as well as
         contingent) to receive any benefits payable under the Plan to a
         beneficiary upon the death of a Participant. The Beneficiary designated
         under this Plan may be the same as or different from the Beneficiary
         designation under any other plan of an Employer in which the
         Participant participates.

10.2     BENEFICIARY DESIGNATION; CHANGE; SPOUSAL CONSENT. A Participant shall
         designate his or her Beneficiary by completing and signing the
         Beneficiary Designation Form, and returning it to the Committee or its
         designated agent. A Participant shall have the right to change a
         Beneficiary by completing, signing and otherwise complying with the
         terms of the Beneficiary Designation Form and the Committee's rules and
         procedures, as in effect from time to time. If the Participant names
         someone other than his or her spouse as a Beneficiary, the Committee
         may, in its sole discretion, determine that spousal consent is required
         to be provided in a form designated by the Committee, executed by such
         Participant's spouse and returned to the Committee. Upon the acceptance
         by the Committee of a new Beneficiary Designation Form, all Beneficiary
         designations previously filed shall be canceled. The Committee shall be
         entitled to rely on the last Beneficiary Designation Form filed by the
         Participant and accepted by the Committee prior to his or her death.

10.3     ACKNOWLEDGMENT. No designation or change in designation of a
         Beneficiary shall be effective until received and acknowledged in
         writing by the Committee or its designated agent.

10.4     NO BENEFICIARY DESIGNATION. If a Participant fails to designate a
         Beneficiary as provided in Sections 10.1, 10.2 and 10.3 above or, if
         all designated Beneficiaries predecease the Participant or die prior to
         complete distribution of the Participant's benefits, then the
         Participant's designated Beneficiary shall be deemed to be his or her
         surviving spouse. If the Participant has no surviving spouse, the
         benefits remaining under the Plan to be paid to a Beneficiary shall be
         payable to the executor or personal representative of the Participant's
         estate.

10.5     DOUBT AS TO BENEFICIARY. If the Committee has any doubt as to the
         proper Beneficiary to receive payments pursuant to this Plan, the
         Committee shall have the right, exercisable in its discretion, to cause
         the Participant's Employer to withhold such payments until this matter
         is resolved to the Committee's satisfaction.

10.6     DISCHARGE OF OBLIGATIONS. The payment of benefits under the Plan to a
         Beneficiary shall fully and completely discharge all Employers and the
         Committee from all further obligations under this Plan with respect to
         the Participant, and that Participant's Plan Agreement shall terminate
         upon such full payment of benefits.

                 TERMINATION OF PLAN, AMENDMENT OR MODIFICATION
                 ----------------------------------------------

11.1     TERMINATION OF PLAN. Although each Employer anticipates that it will
         continue the Plan for an indefinite period of time, there is no
         guarantee that any Employer will continue the Plan or will not
         terminate the Plan at any time in the future. Accordingly, each
         Employer reserves the right to Terminate the Plan (as defined in
         Section 1.41). Following a Termination of the Plan, Participant Account
         Balances shall remain in the Plan until the Participant becomes
         eligible for the benefits provided in Articles 4, 5, 6, 7, 8 or 9 in
         accordance with the provisions of those Articles. The termination of
         the Plan shall not adversely affect any Participant or Beneficiary who
         has become entitled to the payment of any benefits under the Plan as of
         the date of termination.

11.2     AMENDMENT. Any Employer may, at any time, amend or modify the Plan in
         whole or in part with respect to that Employer. Notwithstanding the
         foregoing, (i) no amendment or modification shall be effective to
         decrease the value of a Participant's vested Account Balance in
         existence at the time the amendment or modification is made, (ii) no
         amendment or modification shall be effective to change a deferral
         election or distribution election of a Participant that has been
         submitted to, and accepted by the Committee, prior to the time the
         amendment or modification is made without the consent of the
         Participant, and (iii) no amendment or modification of this Section
         11.2 or Section 12.2 of the Plan shall be effective.

11.3     PLAN AGREEMENT. Despite the provisions of Sections 11.1 and 11.2 above,
         if a Participant's Plan Agreement contains benefits or limitations that
         are not in this Plan document, the Employer may only amend or terminate
         such provisions with the written consent of the Participant.

11.4     EFFECT OF PAYMENT. The full payment of the Participant's vested Account
         Balance under Articles 4, 5, 6, 7, 8, or 9 of the Plan shall completely
         discharge all obligations to a Participant and his or her designated
         Beneficiaries under this Plan, and the Participant's Plan Agreement
         shall terminate.

                                 --------------

12.1     COMMITTEE DUTIES. Except as otherwise provided in this Article 12, this
         Plan shall be administered by a Committee, which shall consist of the
         Board, or such committee as the Board shall appoint. Members of the
         Committee may be Participants under this Plan. The Committee shall also
         have the discretion and authority to (i) make, amend, interpret, and
         enforce all appropriate rules and regulations for the administration of
         this Plan and (ii) decide or resolve any and all questions including
         interpretations of this Plan, as may arise in connection with the Plan.
         Any individual serving on the Committee who is a Participant shall not
         vote or act on any matter relating solely to himself or herself, but
         shall not be prohibited from voting or acting on any matter in which
         such individual's interest is affected in the same manner as other
         Participants generally. When making a determination or calculation, the
         Committee shall be entitled to rely on information furnished by a
         Participant or the Company.

12.2     ADMINISTRATION UPON CHANGE IN CONTROL. For purposes of this Plan, the
         Committee shall be the "Administrator" at all times prior to the
         occurrence of a Change in Control. Within one hundred and twenty (120)

         days following a Change in Control, an independent third party
         "Administrator" may be selected by the individual who, immediately
         prior to the Change in Control, was the Company's Chief Executive
         Officer or, if not so identified, the Company's highest ranking officer
         (the "Ex-CEO"), and approved by the Trustee. The Committee, as
         constituted prior to the Change in Control, shall continue to be the
         Administrator until the earlier of (i) the date on which such
         independent third party is selected and approved, or (ii) the
         expiration of the one hundred and twenty (120) day period following the
         Change in Control. If an independent third party is not selected within
         one hundred and twenty (120) days of such Change in Control, the
         Committee, as described in Section 12.1 above, shall be the
         Administrator. The Administrator shall have the discretionary power to
         determine all questions arising in connection with the administration
         of the Plan and the interpretation of the Plan and Trust including, but
         not limited to benefit entitlement determinations; provided, however,
         upon and after the occurrence of a Change in Control, the Administrator
         shall have no power to direct the investment of Plan or Trust assets or
         select any investment manager or custodial firm for the Plan or Trust.
         Upon and after the occurrence of a Change in Control, the Company must:
         (1) pay all reasonable administrative expenses and fees of the
         Administrator; (2) indemnify the Administrator against any costs,
         expenses and liabilities including, without limitation, attorney's fees
         and expenses arising in connection with the performance of the
         Administrator hereunder, except with respect to matters resulting from
         the gross negligence or willful misconduct of the Administrator or its
         employees or agents; and (3) supply full and timely information to the
         Administrator on all matters relating to the Plan, the Trust, the
         Participants and their Beneficiaries, the Account Balances of the
         Participants, the date and circumstances of the Retirement, Disability,
         death or Termination of Employment of the Participants, and such other
         pertinent information as the Administrator may reasonably require. Upon
         and after a Change in Control, the Administrator may be terminated (and
         a replacement appointed) by the Trustee only with the approval of the
         Ex-CEO. Upon and after a Change in Control, the Administrator may not
         be terminated by the Company.

12.3     AGENTS. In the administration of this Plan, the Committee may, from
         time to time, employ agents and delegate to them such administrative
         duties as it sees fit (including acting through a duly appointed
         representative) and may from time to time consult with counsel who may
         be counsel to any Employer.

12.4     BINDING EFFECT OF DECISIONS. The decision or action of the
         Administrator with respect to any question arising out of or in
         connection with the administration, interpretation and application of
         the Plan and the rules and regulations promulgated hereunder shall be
         final and conclusive and binding upon all persons having any interest
         in the Plan.

12.5     INDEMNITY OF COMMITTEE. All Employers shall indemnify and hold harmless
         the members of the Committee, any Employee to whom the duties of the
         Committee may be delegated, and the Administrator against any and all
         claims, losses, damages, expenses or liabilities arising from any
         action or failure to act with respect to this Plan, except in the case
         of willful misconduct by the Committee, any of its members, any such
         Employee or the Administrator.

12.6     EMPLOYER INFORMATION. To enable the Committee and/or Administrator to
         perform its functions, the Company and each Employer shall supply full

                          -----------------------------

13.1     COORDINATION WITH OTHER BENEFITS. The benefits provided for a
         Participant and Participant's Beneficiary under the Plan are in
         addition to any other benefits available to such Participant under any
         other plan or program for employees of the Participant's Employer. The
         Plan shall supplement and shall not supersede, modify or amend any
         other such plan or program except as may otherwise be expressly
         provided.

                                   ARTICLE 14
                                CLAIMS PROCEDURES
                                -----------------

14.1     PRESENTATION OF CLAIM. Any Participant or Beneficiary of a deceased
         Participant (such Participant or Beneficiary being referred to below as
         a "Claimant") may deliver to the Committee a written claim for a
         determination with respect to the amounts distributable to such
         Claimant from the Plan. If such a claim relates to the contents of a
         notice received by the Claimant, the claim must be made within sixty
         (60) days after such notice was received by the Claimant. All other
         claims must be made within 180 days of the date on which the event that
         caused the claim to arise occurred. The claim must state with
         particularity the determination desired by the Claimant.

14.2     NOTIFICATION OF DECISION. The Committee shall consider a Claimant's
         claim within a reasonable time, but no later than ninety (90) days
         after receiving the claim. If the Committee determines that special
         circumstances require an extension of time for processing the claim,
         written notice of the extension shall be furnished to the Claimant
         prior to the termination of the initial ninety (90) day period. In no
         event shall such extension exceed a period of ninety (90) days from the
         end of the initial period. The extension notice shall indicate the
         special circumstances requiring an extension of time and the date by
         which the Committee expects to render the benefit determination. The
         Committee shall notify the Claimant in writing:

         (a)   that the Claimant's requested determination has been made, and
               that the claim has been allowed in full; or

         (b)   that the Committee has reached a conclusion contrary, in whole or
               in part, to the Claimant's requested determination, and such
               notice must set forth in a manner calculated to be understood by
               the Claimant:

               (i)    the specific reason(s) for the denial of the claim, or any
                      part of it;

               (ii)   specific reference(s) to pertinent provisions of the Plan
                      upon which such denial was based;

               (iii)  a description of any additional material or information
                      necessary for the Claimant to perfect the claim, and an
                      explanation of why such material or information is
                      necessary;

               (iv)   an explanation of the claim review procedure set forth in
                      Section 14.3 below; and

               (v)    a statement of the Claimant's right to bring a civil
                      action under ERISA Section 502(a) following an adverse
                      benefit determination on review.

14.3     REVIEW OF A DENIED CLAIM. On or before sixty (60) days after receiving
         a notice from the Committee that a claim has been denied, in whole or
         in part, a Claimant (or the Claimant's duly authorized representative)
         may file with the Committee a written request for a review of the
         denial of the claim. The Claimant (or the Claimant's duly authorized
         representative):

         (a)   may, upon request and free of charge, have reasonable access to,
               and copies of, all documents, records and other information
               relevant to the claim for benefits;

         (b)   may submit written comments or other documents; and/or

         (c)   may request a hearing, which the Committee, in its sole
               discretion, may grant.

14.4     DECISION ON REVIEW. The Committee shall render its decision on review
         promptly, and no later than sixty (60) days after the Committee
         receives the Claimant's written request for a review of the denial of
         the claim. If the Committee determines that special circumstances
         require an extension of time for processing the claim, written notice
         of the extension shall be furnished to the Claimant prior to the
         termination of the initial sixty (60) day period. In no event shall
         such extension exceed a period of sixty (60) days from the end of the
         initial period. The extension notice shall indicate the special
         circumstances requiring an extension of time and the date by which the
         Committee expects to render the benefit determination. In rendering its
         decision, the Committee shall take into account all comments,
         documents, records and other information submitted by the Claimant
         relating to the claim, without regard to whether such information was
         submitted or considered in the initial benefit determination. The
         decision must be written in a manner calculated to be understood by the
         Claimant, and it must contain:

         (a)   specific reasons for the decision;

         (b)   specific reference(s) to the pertinent Plan provisions upon which
               the decision was based;

         (c)   a statement that the Claimant is entitled to receive, upon
               request and free of charge, reasonable access to and copies of,
               all documents, records and other information relevant (as defined
               in applicable ERISA regulations) to the Claimant's claim for
               benefits; and

         (d)   a statement of the Claimant's right to bring a civil action under
               ERISA Section 502(a).

14.5     LEGAL ACTION. A Claimant's compliance with the foregoing provisions of
         this Article 14 is a mandatory prerequisite to a Claimant's right to
         commence any legal action with respect to any claim for benefits under
         this Plan.

                                      TRUST
                                      -----

15.1     ESTABLISHMENT OF THE TRUST. In order to provide assets from which to
         fulfill the obligations of the Participants and their beneficiaries
         under the Plan, the Company shall establish a trust by a trust
         agreement with a third party, the trustee, to which each Employer may,
         in its discretion, contribute cash or other property, including
         securities issued by the Company, to provide for the benefit payments
         under the Plan, (the "Trust").

15.2     INTERRELATIONSHIP OF THE PLAN AND THE TRUST. The provisions of the Plan
         and the Plan Agreement shall govern the rights of a Participant to
         receive distributions pursuant to the Plan. The provisions of the Trust
         shall govern the rights of the Employers, Participants and the
         creditors of the Employers to the assets transferred to the Trust. Each
         Employer shall at all times remain liable to carry out its obligations
         under the Plan.

15.3     DISTRIBUTIONS FROM THE TRUST. Each Employer's obligations under the
         Plan may be satisfied with Trust assets distributed pursuant to the
         terms of the Trust, and any such distribution shall reduce the
         Employer's obligations under this Plan.

                                   ARTICLE 16
                                  MISCELLANEOUS
                                  -------------

16.1     STATUS OF PLAN. The Plan is intended to be a plan that is not qualified
         within the meaning of Code Section 401(a) and that "is unfunded and is
         maintained by an employer primarily for the purpose of providing
         deferred compensation for a select group of management or highly
         compensated employees" within the meaning of ERISA Sections 201(2),
         301(a)(3) and 401(a)(1). The Plan shall be administered and interpreted
         to the extent possible in a manner consistent with that intent.

16.2     UNSECURED GENERAL CREDITOR. Participants and their Beneficiaries,
         heirs, successors and assigns shall have no legal or equitable rights,
         interests or claims in any specific property or assets of an Employer.
         For purposes of the payment of benefits under this Plan, any and all of
         an Employer's assets shall be, and remain, the general, unpledged
         unrestricted assets of the Employer. An Employer's obligation under the
         Plan shall be merely that of an unfunded and unsecured promise to pay
         money in the future.

16.3     EMPLOYER'S LIABILITY. An Employer's liability for the payment of
         benefits shall be defined only by the Plan and the Plan Agreement, as
         entered into between the Employer and a Participant. An Employer shall
         have no obligation to a Participant under the Plan except as expressly
         provided in the Plan and his or her Plan Agreement.

16.4     NONASSIGNABILITY. Neither a Participant nor any other person shall have
         any right to commute, sell, assign, transfer, pledge, anticipate,
         mortgage or otherwise encumber, transfer, hypothecate, alienate or
         convey in advance of actual receipt, the amounts, if any, payable
         hereunder, or any part thereof, which are, and all rights to which are
         expressly declared to be, unassignable and non-transferable. No part of
         the amounts payable shall, prior to actual payment, be subject to
         seizure, attachment, garnishment or sequestration for the payment of
         any debts, judgments, alimony or separate maintenance owed by a
         Participant or any other person, be transferable by operation of law in

         the event of a Participant's or any other person's bankruptcy or
         insolvency or be transferable to a spouse as a result of a property
         settlement or otherwise.

16.5     NOT A CONTRACT OF EMPLOYMENT. The terms and conditions of this Plan
         shall not be deemed to constitute a contract of employment between any
         Employer and the Participant. Such employment is hereby acknowledged to
         be an "at will" employment relationship that can be terminated at any
         time for any reason, or no reason, with or without cause, and with or
         without notice, unless expressly provided in a written employment
         agreement. Nothing in this Plan shall be deemed to give a Participant
         the right to be retained in the service of any Employer, either as an
         Employee or a Director, or to interfere with the right of any Employer
         to discipline or discharge the Participant at any time.

16.6     FURNISHING INFORMATION. A Participant or his or her Beneficiary will
         cooperate with the Committee by furnishing any and all information
         requested by the Committee and take such other actions as may be
         requested in order to facilitate the administration of the Plan and the
         payments of benefits hereunder, including but not limited to taking
         such physical examinations as the Committee may deem necessary.

16.7     TERMS. Whenever any words are used herein in the masculine, they shall
         be construed as though they were in the feminine in all cases where
         they would so apply; and whenever any words are used herein in the
         singular or in the plural, they shall be construed as though they were
         used in the plural or the singular, as the case may be, in all cases
         where they would so apply.

16.8     CAPTIONS. The captions of the articles, sections and paragraphs of this
         Plan are for convenience only and shall not control or affect the
         meaning or construction of any of its provisions.

16.9     GOVERNING LAW. Subject to ERISA, the provisions of this Plan shall be
         construed and interpreted according to the internal laws of the State
         of Delaware without regard to its conflicts of laws principles. Venue
         shall lie in Wilmington, Delaware.

16.10    NOTICE. Any notice or filing required or permitted to be given to the
         Committee under this Plan shall be sufficient if in writing and
         hand-delivered, or sent by registered or certified mail, to the address
         below:

================================================================================

         Any notice or filing required or permitted to be given to a Participant
         under this Plan shall be sufficient if in writing and hand-delivered,
         or sent by mail, to the last known address of the Participant.

16.11    SUCCESSORS. The provisions of this Plan shall bind and inure to the
         benefit of the Participant's Employer and its successors and assigns
         and the Participant and the Participant's designated Beneficiaries.

16.12    SPOUSE'S INTEREST. The interest in the benefits hereunder of a spouse
         of a Participant who has predeceased the Participant shall
         automatically pass to the Participant and shall not be transferable by
         such spouse in any manner, including but not limited to such spouse's
         will, nor shall such interest pass under the laws of intestate
         succession.

16.13    VALIDITY. In case any provision of this Plan shall be illegal or
         invalid for any reason, said illegality or invalidity shall not affect
         the remaining parts hereof, but this Plan shall be construed and
         enforced as if such illegal or invalid provision had never been
         inserted herein.

16.14    INCOMPETENT. If the Committee determines in its discretion that a
         benefit under this Plan is to be paid to a minor, a person declared
         incompetent or to a person incapable of handling the disposition of
         that person's property, the Committee may direct payment of such
         benefit to the guardian, legal representative or person having the care
         and custody of such minor, incompetent or incapable person. The
         Committee may require proof of minority, incompetence, incapacity or
         guardianship, as it may deem appropriate prior to distribution of the
         benefit. Any payment of a benefit shall be a payment for the account of
         the Participant and the Participant's Beneficiary, as the case may be,
         and shall be a complete discharge of any liability under the Plan for
         such payment amount.

16.15    COURT ORDER. The Committee is authorized to comply with any court order
         in any action in which the Plan or the Committee has been named as a
         party, including any action involving a determination of the rights or
         interests in a Participant's benefits under the Plan. Notwithstanding
         the foregoing, the Committee shall interpret this provision in a manner
         that is consistent with applicable tax law, including but not limited
         to guidance issued after the effective date of this Plan.

16.16    DEDUCTION LIMITATION ON BENEFIT PAYMENTS. If an Employer determines in
         good faith that there is a reasonable likelihood that any compensation
         paid to a Participant for a taxable year of the Employer would not be
         deductible by the Employer solely by reason of the limitation under
         Code Section 162(m), then to the extent deemed necessary by the
         Employer to ensure that the entire amount of any distribution to the
         Participant pursuant to this Plan is deductible, the Employer may defer
         all or any portion of a distribution under this Plan. Any amounts
         deferred pursuant to this limitation shall continue to be
         credited/debited with additional amounts in accordance with Section 3.9
         above, even if such amount is being paid out in installments. The
         amounts so deferred and amounts credited thereon shall be distributed
         to the Participant or his or her Beneficiary (in the event of the
         Participant's death) at the earliest possible date, as determined by
         the Employer in good faith, on which the deductibility of compensation
         paid or payable to the Participant for the taxable year of the Employer
         during which the distribution is made will not be limited by Section
         162(m).

16.17    INSURANCE. The Employers, on their own behalf or on behalf of the
         trustee of the Trust, and, in their sole discretion, may apply for and
         procure insurance on the life of the Participant, in such amounts and
         in such forms as the Trust may choose. The Employers or the trustee of
         the Trust, as the case may be, shall be the sole owner and beneficiary
         of any such insurance. The Participant shall have no interest
         whatsoever in any such policy or policies, and at the request of the
         Employers shall submit to medical examinations and supply such
         information and execute such documents as may be required by the
