4.    DEFERRED COMPENSATION ACCOUNT

      4.1.  ESTABLISHMENT OF DEFERRED COMPENSATION ACCOUNT. In partial
            consideration for a Participant's entering into an Option
            Cancellation Agreement, the Company shall establish a Deferred
            Compensation Account for such Participant. The Deferred Compensation
            Account of each Participant shall initially be credited with a
            notional amount (i.e., an actual cash amount will not be deposited)
            equal to such Participant's Option Cancellation Deferred Amount. The
            Option Cancellation Deferred Amount of each Participant shall be
            deemed invested (i.e., an actual investment will not be made), as of
            the Effective Date, in LLC Class A Units and such deemed investment
            shall be represented by a number of Notional Class A Units equal to
            such Participant's Option Cancellation Deferred Amount divided by
            $999.90. All amounts in a Participant's

                                       3

            Deferred Compensation Account shall be subject to the claims of the
            creditors of the Company.

      4.2.  AMOUNT OF PAYOUT.

            (a)   Upon each distribution to holders of LLC Class A Units by
                  Investors LLC (including, without limitation, any distribution
                  in connection with an Exit Event), the Company shall make a
                  payment to each Participant equal to the number of Notional
                  Class A Units then credited to such Participant's Deferred
                  Compensation Account multiplied by the per LLC Class A Unit
                  amount distributed by Investors LLC to holders of LLC Class A
                  Units in such distribution. The amount of any such payment
                  received by a Participant shall be debited against the
                  Deferred Compensation Account of such Participant.

            (b)   In the event that LLC Class A Units are sold by one or more
                  holders of LLC Class A Units (other than to a Permitted
                  Transferee (excluding any Covered Sale)), the Company shall,
                  at the option of each Participant, pay to such Participant the
                  result obtained by multiplying (i) the lesser of (A) the
                  amount of such Participant's Deferred Compensation Account (as
                  previously credited or debited under the provisions of
                  Sections 4.1 and 4.2(a) and this Section 4.2(b)) and (B) the
                  fair value of such Participant's Deferred Compensation Account
                  (as determined below in this Section 4.2(b)), by (ii) a
                  fraction (the "Fraction"), in which the numerator equals the
                  number of LLC Class A Units being sold by such holder or
                  holders and the denominator of which is the number of all LLC
                  Class A Units outstanding immediately prior to such sale. If a
                  Participant elects to participate in such sale: (x) the amount
                  of Notional Class A Units credited to such Participant shall
                  be reduced immediately following the distribution to such
                  Participant as a result of such sale by an amount equal to the
                  total Notional Class A Units credited to such Participant
                  immediately prior to such sale (the "Pre-Sale Notional Class A
                  Amount") multiplied by the Fraction (such product being the
                  "Debited Units") and (y) such Participant's Deferred
                  Compensation Account shall be debited by an amount equal to
                  the Debited Units multiplied by a fraction, the numerator of
                  which is the amount of such Participant's Deferred
                  Compensation Account (as previously credited or debited under
                  the provisions of Sections 4.1 and 4.2(a) and this Section
                  4.2(b)) immediately prior to such sale and the denominator of
                  which is such Participant's Pre-Sale Notional Class A Amount.
                  For purposes of clause (i)(B) of the first sentence of this
                  Section 4.2(b), the fair value of a Participant's Deferred
                  Compensation Account shall equal the amount per LLC Class A
                  Unit received in the applicable sale transaction by a holder
                  or holders of LLC Class A

                                       4

                  Units (and in the case such amount includes non-cash
                  consideration, the value thereof shall be determined by the
                  Management Committee in good faith) multiplied by such
                  Participant's Pre-Sale Notional Class A Amount applicable to
                  such sale transaction.

      4.3.  METHOD OF PAYMENT. All payments made with respect to any
            Participant's Deferred Compensation Account shall be paid in cash,
            except that in the event of a Change in Control or Exit Event in
            which all or a portion of the consideration effecting such
            transaction is non-cash consideration, at the Company's option any
            such payment may be made in the form of such non-cash consideration
            (provided that in the event of a transaction in which only a portion
            of the consideration is non-cash consideration, Participants shall
            receive the same proportion of cash and non-cash consideration as
            holders of LLC Class A Units receive). The fair market value of any
            such non-cash consideration shall be determined by the Management
            Committee of Investors LLC and shall be valued consistently with the
            determination of such value for purposes of Investors LLC.

      4.4.  SATISFACTION OF PAYMENT OBLIGATIONS. At such time as the amount of
            any Participant's Deferred Compensation Account has been reduced to
            zero by reason of the payments under Section 4.2, the Company shall
            have no further obligations to such Participant in respect of such
            Participant's Deferred Compensation Account.

      4.5.  AWARD AGREEMENT. The establishment of a Deferred Compensation
            Account for any Participant shall be evidenced by an Option
            Cancellation Agreement that shall be signed on behalf of the Company
            and the Participant. Such Option Cancellation Agreement shall set
            forth the deemed investment in LLC Class A Units initially credited
            to the Participant's Deferred Compensation Account.

      4.6.  SUBDIVISION OR COMBINATION OF LLC CLASS A UNITS. In the event of a
            subdivision (including by way of dividend) of the number of
            outstanding LLC Class A Units into a greater number or in the event
            of a combination of outstanding LLC Class A Units into a smaller
            number, then the number of Notional Class A Units shall be
            subdivided or combined so as to represent the same proportion of
            outstanding LLC Class A Units immediately following the subdivision
            or combination of Notional Class A Units and LLC Class A Units as
            was represented by the number of Notional Class A Units outstanding
            immediately prior to the subdivision or combination of Notional
            Class A Units and LLC Class A Units.

                                       5

            authority that may be necessary or helpful to enable it to discharge
            its responsibilities with respect to the Plan.

      5.2.  DELEGATION OF AUTHORITY. The Committee may delegate to one or more
            of its members, or to one or more agents, such administrative duties
            as it may deem advisable; provided, however, that any such
            delegation shall be in writing. In addition, the Committee, or any
            person to whom it has delegated duties under this Section 5.2, may
            employ one or more persons to render advice with respect to any
            responsibility the Committee or such person may have under the Plan.
            The Committee may employ such legal or other counsel, consultants
            and agents as it may deem desirable for the administration of the
            Plan and may rely upon any opinion or computation received from any
            such counsel, consultant or agent.

6.    WITHHOLDING TAXES. The Company may require a Participant to reimburse the
      Company for any taxes required by any governmental authority to be
      withheld or otherwise deducted and paid by the Company or any Subsidiary
      in respect of the payment of any amounts paid under the Plan. In lieu
      thereof, the Company or Subsidiary shall have the right to withhold the
      amount of such taxes from any other payments due or to become due from the
      Company or the Subsidiary to the Participant upon such reasonable terms
      and conditions as the Committee shall prescribe.

            represent a majority of all the notional amounts held in all such
            Deferred Compensation Accounts at the time of determination;
            provided, that no amendment, termination or suspension shall have
            any effect with respect to a Participant if it adversely affects the
            amount of any payment or the timing of any payment to such
            Participant under the Plan, unless such Participant consents to such
            amendment, termination or suspension in writing.

8.    MISCELLANEOUS

      8.1.  TRANSFERABILITY. Each Deferred Compensation Account under the Plan
            and any interest therein shall not be transferable otherwise than by
            will or the laws of descent and distribution. Any purported transfer

            shall be void.

            obligations under the Plan. Nothing contained in the Plan, and no
            action taken pursuant to its provisions, shall create a trust of any
            kind, or a fiduciary relationship between the Company and any
            Participant, beneficiary, legal representative or any other person.
            Unless otherwise agreed in writing by the Company, a Participant
            shall not take any position inconsistent with such treatment by the

            general funds of the Company, and participants' right to payment is
            unsecured. The Plan is not intended to be subject to the Employee
            Retirement Income Security Act of 1974, as amended.

      8.3.  NO RIGHT TO CONTINUED EMPLOYMENT OR SERVICE. The Participant's
            rights, if any, to continue to serve the Company or any Subsidiary
            of the Company as an employee, director or consultant shall not be
            enlarged or otherwise affected by his or her designation as a
            Participant under the Plan, and the Company or the applicable
            Subsidiary reserves the right to terminate the employment or
            engagement of any employee, director or consultant at any time.
            Except as contemplated by Section 4.2(c) hereof, such termination

            compensation for purposes of computing benefits under any retirement
            plan of the Company or any Subsidiary nor affect any benefits or
            compensation under any other benefit or compensation plan of the
            Company or any Subsidiary now or subsequently in effect.
