     provision contained in this Agreement shall entitle any Member to obtain
     employment with or remain in the employment of the Company or any of its
     Subsidiaries or Affiliates or affect any right the Company or any
     Subsidiary or Affiliate of the Company may have to terminate the Member's

          (a) The Company hereby designates JPMP as the "Tax Matters Partner"

12.  Repurchase of Other Member Units.

     The provisions set forth in this Section 12 shall apply to the Other
Members and any Permitted Transferee of such Other Members.

          (a) In the event that such Other Member's employment with the Company,
its Subsidiaries or their Affiliates is terminated for any reason at any time,
JPMP or its designee


                                       11
<PAGE>
shall have the right (but not the obligation), upon delivery of a Repurchase
Notice to such Other Member, to repurchase all of the Other Member Units owned
by such Other Member and its Transferees (the "Repurchase Right"). If JPMP or
its designee elects to exercise the Repurchase Right, JPMP or its designee shall
deliver the Repurchase Notice on or before the 180th day after the Employment
Termination Date. The closing of any repurchase of Other Member Units pursuant
to this Section 12 shall occur on or before the date that is 30 days after the
date of delivery of the Repurchase Notice.

          (b) In the event JPMP or its designee elects to exercise its
Repurchase Right, the repurchase price shall be determined as set forth below.

               (i) In the event that an Other Member's employment with the
     Company, its Subsidiaries or their Affiliates is terminated for any reason
     (other than a termination (i) for Good Reason, (ii) without Cause or (iii)
     upon the death or Disability of such Other Member), the price to be paid by
     JPMP or its designee to repurchase each Vested Unit shall be an amount
     equal to $.01 (as adjusted for splits, combinations, recapitalizations and
     similar transactions).

               (ii) In the event that an Other Member's employment with the
     Company, its Subsidiaries or their Affiliates is terminated for (A) Good
     Reason, (B) without Cause or (C) due to death or Disability of such Other
     Member, the price to be paid by JPMP or its designee to repurchase each
     Vested Unit shall be an amount equal to the fair market value of such Units
     as of the Employment Termination Date. The determination of fair market
     value of such Vested Units shall be made by the good faith majority
     decision of a committee (the "Fair Market Value Evaluation Committee)
     consisting of (1) two designees of JPMP and (2) the Chief Executive Officer
     of Parent at such time. In the event that the Fair Market Value Evaluation
     Committee is to determine the value of Vested Units owned by the Chief
     Executive Officer of Parent, the third member of the Fair Market Value
     Evaluation Committee shall be Neil Dyment or the Chief Financial Officer of
     Parent at such time.

               (iii) In the event that an Other Member's employment with the
     Company, its Subsidiaries or their Affiliates is terminated for any reason,
     the price to be paid by JPMP or its designee to repurchase each Unvested
     Unit shall be $.01 (as adjusted for splits, combinations, recapitalizations
     and similar transactions).

               (iv) The purchase price to be paid by JPMP or its designees shall
     be paid in cash in a single lump sum payment. The Persons purchasing the
     Units pursuant to this Section 12 will be entitled to require such Other
     Member to provide representations and warranties regarding (i) his or its
     power, authority and legal capacity to enter into such Transfer; (ii) valid
     right, title and interest in such Units and the Other Member's ownership of
     such Units; (iii) the absence of any Encumbrances on such Units; and (iv)
     the absence of any violation, default, or acceleration of any agreement or
     instrument pursuant to which such Other Member or the assets of such Other
     Member are bound as the result of such sale. JPMP or its designee shall
     have the right to revoke the Repurchase Notice at any time. Should JPMP or
     any of its designees elect to exercise the purchase rights pursuant to this
     Section 12 and such Other Member fails to deliver all of


                                       12
<PAGE>
     such Units in accordance with the terms hereof, JPMP may, at its option, in
     addition to all other remedies it may have, deliver the purchase price to
     the Company to be held for the benefit of and payment over to such Other
     Member in accordance herewith, whereupon (i) the Company shall cancel on
     its books the such Units registered in the name of the Other Member and
     (ii) issue to the purchaser, in lieu thereof, Units registered in the
     purchaser's name (or if the Company is the purchaser, cancel such Units),
     and all of such Other Member's right, title, and interest in and to such
     Units shall terminate in all respects.

          (c) Notwithstanding the foregoing, in the event that any Other
Member's employment with the Company, its Subsidiaries or their Affiliates is
terminated for any reason at any time and such Other Member has Transferred
Other Member Units to a Permitted Transferee, JPMP or its designee shall have
the right (but not the obligation), upon delivery of a Repurchase Notice to such
Permitted Transferee, to repurchase all of the Other Member Units owned by such
Permitted Transferee in accordance the provisions of this Section 12 on the same
terms and conditions as if JPMP or its designee were to repurchase such Other
Member Units directly from the Person who originally Transferred such Other
Member Units to such Permitted Transferee.

13.  Transfers of Units and Interests.

          (a) Except as required by Sections 12, 13(b), or 13(c), no Member may
sell, assign, pledge or otherwise transfer or encumber (collectively,
"Transfer"), other than to Permitted Transferees in accordance with the terms
hereof, all or any part of its Units or other part of its Interest, and no
transferees of all or any part of the Units of a Member shall be admitted as a
substituted Member, without, in either event, having obtained the prior written
consent of a Majority in Interest of the Members, which consent may be withheld
in their sole discretion. Any Transfer or attempted Transfer of any Interest in
the Company in violation of any the provisions of this Section 13 shall be void,
and the Company shall not record such Transfer on its books or treat any
purported transferee of such Units as the owner of such Units for any purpose.
The Company shall amend Schedule II hereto from time to time to reflect
Transfers made in accordance with, and as permitted under, this Section 13. Upon
the Transfer of all Units held by a Member, such Person shall no longer be
deemed to be a "Member" hereunder and shall have no rights as a "Member"
hereunder.

          (b) If the Board of Managers approves a Sale Transaction, each Other
Member shall consent to and raise no objections against the Sale Transaction,
and if the Sale Transaction is structured as a sale of the issued and
outstanding Securities of the Company (whether by merger, recapitalization,
consolidation or sale or transfer of Units or otherwise), then each Other Member
shall waive any dissenters rights, appraisal rights or similar rights in
connection with such Sale Transaction and each Other Member shall agree to sell
his or her Units on the terms and conditions approved by the Board of Managers.
Each Other Member shall take all necessary and desirable actions in connection
with the consummation of the Sale Transaction, including, but not limited to,
the execution of such agreements and instruments (including Member resolutions)
and other actions necessary to provide the representations, warranties,
indemnities, covenants, conditions, escrow agreement and other provisions and
agreements relating to such Sale Transaction. In the event that any Other Member
fails for any


                                       13
<PAGE>
reason to take any of the foregoing actions after reasonable notice thereof, he
or it hereby grants an irrevocable power of attorney and proxy to the Company to
take all necessary actions and execute and deliver all documents deemed by the
Company necessary to effectuate the terms of this Section 13(b).

          (c) If and whenever the Company proposes to register any of its
Securities under the Securities Act for its own account (or otherwise), each
Other Member agrees not to effect (other than pursuant to such registration) any
public sale or distribution (including, but not limited to, any sale pursuant to
Rule 144 or Rule 144A of the Securities Act) of any Units or any other
Securities of the Company until 180 days after (or with respect to the Company's
initial public offering of Units under the Securities Act 270 days after), and
during the twenty (20) days prior to, the effective date of such registration.

          (d) Notwithstanding anything to the contrary contained herein, JPMP
may Transfer any Units to any employee, officer, director or consultant of the
Company or its Subsidiaries.

          (e) No Transfer of any Other Member Units by any Other Member to a
Permitted Transferee shall become effective until the Permitted Transferee
(unless already party to this Agreement) executes and delivers to the Company a
Joinder. Upon such Permitted Transfer and such execution and delivery, the
Permitted Transferee shall be bound by, and entitled to the benefits of, this
Agreement.

14.  Withdrawal.

          No Member shall have the right to withdraw from the Company except
with the consent of the Board of Managers. The provisions hereof with respect to
distributions upon withdrawal are exclusive, and no Member shall be entitled to
claim any further or different distribution upon withdrawal under Section 18-604
of the Delaware Act or otherwise.

15.  Additional Members.

          The Board of Managers shall have the right to cause the Company to
issue additional Units and to admit additional Members upon the acquisition of
such Units upon such terms and conditions, at such time or times, and for such
Capital Contributions as shall be determined by the Board of Managers. In
connection with the admission of an additional Member, the Company shall amend
Schedule II hereof to reflect the name, address of and the number of Units held
by, the additional Member. Prior to the admission of any Person as a Member,
such Person shall execute a Joinder.

16.  Dissolution.

          (a) The Company shall be dissolved and its affairs wound up and
terminated upon the first to occur of the following:

               (i) March 13, 2023; or

               (ii) the determination of the Board of Managers and a Majority in
     Interest of the Members to dissolve the Company.

reasonable discretion of the Board of Managers, to preserve the value of the
Company's assets during the period of dissolution and liquidation.

          (c) Distributions to the Members in liquidation may be made in cash or

dissolution and liquidation shall be allocated among the Members in accordance
with the provisions of Section 8.

          (e) The assets of the Company (including, without limitation, proceeds
from the sale or other disposition of any assets during the period of
dissolution and liquidation) shall be applied as follows:

               (i) First, to repay any indebtedness of the Company, whether to
     third parties or the Members, in the order of priority required by law;

               (ii) Second, to any reserves which the Board of Managers
     reasonably deems necessary for contingent or unforeseen liabilities or
     obligations of the Company (which reserves when they become unnecessary
     shall be distributed in accordance with the provisions of (iii), below);
     and

               (iii) Third, to the Members in accordance with Section 9.

17.  Limitation on Liability.

          The debts, obligations and liabilities of the Company, whether arising
in contract, tort or otherwise, shall be solely the debts, obligations and
liabilities of the Company, and no Member of the Company shall be obligated
personally for any such debt, obligation or liability of the Company solely by
reason of being a Member. No Member shall be liable to the Company, any other
Member or any third party for any breach of any representation or warranty or
failure by the Company to comply with any of its covenants or agreements
contained in this Agreement.
