Units less $722,600,000 and (2) the
denominator of which is $722,600,000; and (iii)
following the attainment of the Second Performance Hurdle, all of the Class C-2
Units held by such holder.  For avoidance of doubt, immediately prior
to any distribution by the Company that will result in the vesting of any C-2
Units, the Company will determine how many of the C-2 Units will vest as a
result of such distribution (after taking into account the reduction in the
amount of such distribution to be made with respect to the Class B Units as a
result of the need to make distributions to such newly vested Class C-2 Units),
and such distribution will be made to the Unitholders in the manner provided in
Section 4.4(a)
below, treating such newly vested Class C-2 Units as Vested Class C-2
Units.  At such time as the employment or engagement of a holder of
Class C-2 Units with NTK Holdings or its subsidiaries terminates, such holder
shall forfeit all Class C-2 Units held by such holder that are not vested at
such time and such forfeited Units shall be deemed cancelled.

provided in the Act and otherwise by law. Except as otherwise expressly provided
for herein, the Members hereby consent to the exercise by the Management
Committee of all such powers and rights conferred on them by the Act with
respect to the management and control of the Company.  Notwithstanding
the foregoing and except as explicitly set forth in this Agreement, if a vote,
consent or approval of the Members is required by the Act or other applicable
law with respect to any act to be taken by the Company or matter considered by
the Management Committee, each Member agrees that it shall be deemed to have
consented to or approved such act or voted on such matter in accordance with a
vote of the Management Committee on such act or matter.  No Member, in
its capacity as a Member, shall have any power to act for, sign for or do any
act that would bind the Company.  The Members, acting through the
Management Committee, shall devote such time and effort to the affairs of the
Company as they may deem appropriate for the oversight of the management and
affairs of the Company.  Each Member acknowledges and agrees that,
except as otherwise agreed in writing, no Member shall, in its capacity as a
Member, be bound to devote all of such Member’s business time to the affairs of
the Company, and that each Member and such Member’s Affiliates do and will
continue to engage for such Member’s own account and for the account of others
in other business ventures.




(b)  Delegation by Management
Committee.  Except as provided in Section 3.1(c) below, the
Management Committee shall not have the power and authority to delegate to one
or more other Persons the Management Committee’s rights and powers to manage and
control the business and affairs of the Company; provided, however that the
Management Committee may authorize any Person (including, without limitation,
any Member, Officer or Representative) to enter into and perform under any

Company.

Management Committee may, from time to time, designate one or more committees,
each of which shall be comprised of at least two Representatives and shall have
such membership as is required by Article VIII of the Securityholders Agreement.

the authority of the Management Committee.  At every meeting of any
such committee, the presence of a majority of all the representatives thereof
shall constitute a quorum, and the affirmative vote of a majority of the

whom shall be individuals (“Representatives”) who
shall be elected by a majority vote of the holders of Class B Units and each
such Member shall have one vote for each Class B Unit held by such
Member.  Subject to the terms of the Securityholders Agreement, any
Representative may be removed from the Management Committee at any time by the
holders of a majority of the total voting power of the outstanding Class B
Units.  Each Representative shall remain in office until his or her
death, resignation or removal, and in the event of death, resignation or removal

Representative shall fill the vacancy created.  From August 26, 2004
through the completion of the First Merger, the members of the Management
Committee shall be Anthony J. DiNovi and Kent R. Weldon and each of them shall

Representatives, in the performance of their duties, shall owe to the Company
and the Members duties of loyalty and due care of the type owed by the directors

State of Delaware; provided, that to the maximum extent permitted from time to
time under the law of the State of Delaware applying to corporations, this
Company renounces any interest or expectancy of the Company in, or in being
offered an opportunity to participate in, business opportunities that are from
time to time presented to its Representatives, other than those Representatives
who are employees of NTK Holdings, Holdings or Nortek.

power of the absent Representative, and references herein to a “Representative”
at a meeting shall be deemed to include his or her substitute. Notwithstanding
anything in this Agreement to the contrary, Representatives, in their capacities
as such, shall not be deemed to be “members” or “managers” (as such terms are
defined in the Act) of the Company; provided that, for
the purpose of clarity and the avoidance of doubt, nothing contained in this
sentence shall relieve or diminish any Representative’s duties under Section 3.2(b)

provision of this Section 3.2 is

meeting of the Management Committee at which action on any matter is taken shall
be presumed to have assented to the action unless his dissent shall be entered
in the minutes of the meeting or unless he shall file his written dissent to
such action with the Person acting as secretary of the meeting before the

after the adjournment of the meeting. Such right to dissent shall not apply to a
Representative who voted in favor of such action.

called or convened.

Meetings.  Regular meetings of the Management Committee shall
be held at such times and places as shall be designated from time to time by

Committee, the chairman shall have no authority or power to act for or on behalf
of the Company, to do any act that would be binding on the Company or to make
any expenditure or incur any obligations on behalf of the Company or authorize
any of the foregoing.  The chairman shall initially be Richard L.
Bready and shall continue to be Mr. Bready for the period during which he is a
Representative of the Company.




SECTION
3.5  Approval or Ratification of
Acts or Contracts.  Any act or contract that shall be approved
or be ratified by the Management Committee on behalf of the Company shall be as
valid and as binding upon the Company and upon all the Members (in their
capacity as Members) as if it shall have been approved or ratified by every
Member of the Company; provided, that no action taken under this Section 3.5
shall bind any party other than the Company with respect to the Securityholders
Agreement, the Senior Management Unit Subscription Agreements (as defined in the
Securityholders Agreement) and the Option Cancellation Agreements (as defined in

Telephone Conference.  Any action permitted or required by the
Act, the Certificate or this Agreement to be taken at a meeting of the
Management Committee or any committee designated by the Management Committee may
be taken without a meeting if a consent in writing, setting forth the action to
be taken, is signed by a majority of the Representatives or members of such
other committee, as the case may be.  Such consent shall have the same
force and effect as a vote at a meeting and may be stated as such in any
document or instrument filed with the Secretary of State of the State of
Delaware, and the execution of such consent shall constitute attendance or
presence in person at a meeting of the Management Committee or any such other
committee, as the case may be. Subject to the requirements of this Agreement for
notice of meetings, the Representatives, or representatives of any other

and other documents as are required by the applicable statutes, rules or
regulations of any such jurisdiction or as are required to reflect the identity
of the Members and the amounts of their respective capital

property shall not be required to return to any Person any such money or
property. However, if any court of competent jurisdiction holds that,

or any inquiry or investigation that could lead to such a Proceeding, by reason
of the fact that he, she, or it, or a Person of which he, she or it is the legal
representative, is or was a Unitholder, Officer or Representative shall be
indemnified by the Company to the fullest extent permitted by applicable law, as

similar taxes and punitive damages), fines, settlements and reasonable expenses
(including reasonable attorneys’ fees and expenses) actually incurred by such
Person in connection with such Proceeding, appeal, inquiry or investigation if
such Person acted in Good Faith, and indemnification under this Section 3.11
shall continue as to a Person who has ceased to serve in the capacity which
initially entitled such Person to indemnity hereunder.  A
Representative shall not be liable to the Company or its Members for monetary
damages for breach of fiduciary duty as a Representative if such Person acted in
Good Faith, except to the extent that exculpation from liability is not
permitted under applicable law as in effect at the time such liability is
determined.  The rights granted pursuant to this Section 3.11 shall be
deemed contract rights, and no amendment, modification or repeal of this Section
3.11 shall have the effect of limiting or denying any such rights with respect
to actions taken or Proceedings, appeals, inquiries or investigations arising
prior to any amendment, modification or repeal. It is expressly acknowledged
that the indemnification provided in this Section 3.11 could involve
indemnification for negligence or under theories of strict liability. “Good

allocation to a Unitholder of a share of Net Income or Net Loss shall be treated
as an allocation of the same share of each item of income, gain, loss or
deduction that is taken into account in computing Net Income or Net
Loss.




(b)  General
Allocations.




(i)  Net Income and Net
Loss.  After giving effect to the special allocations provided
in Sections
4.3(c) all Net Income and Net Loss of the Company for a fiscal year shall
be allocated to the Unitholders as follows:




(A)  first, Net Income
will be allocated to the Unitholders having deficit balances in their Capital
Accounts (computed after giving effect to all contributions, distributions,
allocations and other Capital Account adjustments for all taxable years (other
than the items comprising the Net Income or Net Loss of the Company being
allocated to the Unitholders for the current fiscal year), after adding back
each Unitholder’s share of Company Minimum Gain and Member Minimum Gain as
provided in Regulations Sections 1.704-2(g) and 1.704-2(i)(5)), to the extent
of, and in proportion to, those deficits, unless satisfied by allocations under
Section 4.3(c)
hereof; and




(B)  second, Net Income
and Net Loss not allocated under Section 4.3(b)(i)(A)
will be allocated so as to cause the credit balance in each Unitholder’s Capital
Account (computed in the same manner as provided parenthetically in Section 4.3(b)(i)(A)
hereof) to equal, as nearly as possible, the amount such Unitholder would
receive if the Company sold all of its assets for the Gross Asset Value of each
such asset and distributed the proceeds thereof (after satisfaction of any
liabilities of the Company) in accordance with the provisions of Section 4.4
hereof.




(c)  Additional Allocation
Provisions.  Notwithstanding the foregoing provisions of this
Section 4.3:




(i)




(A)  If there is a net
decrease in Company Minimum Gain or Member Minimum Gain during any fiscal year,
the Unitholders shall be allocated items of Company income and gain for such
fiscal year (and, if necessary, for subsequent fiscal years) in accordance with
Regulations Section 1.704-2(f) or 1.704-2(i)(4), as applicable.  It is
intended that this Section 4.3(c)(i)(A)
qualify and be construed as a “minimum gain chargeback” and a “chargeback of
partner nonrecourse debt minimum gain” within the meaning of such Regulations,
which shall be controlling in the event of a conflict between such Regulations
and this Section
4.3(c)(i)(A).




(B)  Any Nonrecourse
Deductions for any fiscal year shall be specially allocated to the holders of
Class A Units in accordance with the number of Class A Units held by each such
Unitholder.  Any Member Nonrecourse Deductions for any fiscal year
shall be specially allocated to the Unitholder(s) who bears the economic risk of
loss with respect to the Member Nonrecourse Debt to which such Member
Nonrecourse Deductions are attributable, in accordance with Regulations Section
1.704- 2(i).




(C)  If any Unitholder
unexpectedly receives an adjustment, allocation or distribution described in
Regulations Section 1.704- 1(b)(2)(ii)(d)(4), (5) or (6), items of Company
income and gain shall be allocated, in accordance with Regulations Section
1.704- 1(b)(2)(ii) (d), to the Unitholder in an amount and manner sufficient to
eliminate, to the extent required by such Regulations, the Adjusted Capital
Account Deficit of the Unitholder as quickly as possible.  It is
intended that this Section 4.3(c)(i)(C)
qualify and be construed as a “qualified income offset” within the meaning of
Regulations 1.704- 1(b)(2)(ii)(d), which shall be controlling in the event of a
conflict between such Regulations and this Section
4.3(c)(i)(C).




(D)  The allocations set
forth in Sections
4.3(c)(i)(A), (B)and (C) (the “Regulatory
Allocations”) are intended to comply with certain regulatory
requirements, including the requirements of Regulations Sections 1.704-1(b) and
1.704-2. Notwithstanding the provisions of Section 4.3(b), the
Regulatory Allocations shall be taken into account in allocating other items of
income, gain, loss and deduction among the Unitholders so that, to the extent
possible, the net amount of such allocations of other items and the Regulatory
Allocations to each Unitholder shall be equal to the net amount that would have
been allocated to each such Unitholder if the Regulatory Allocations had not
occurred.




(ii)  For any fiscal year
during which a Unitholder’s interest in the Company is assigned by such
Unitholder, the portion of the Net Income and Net Loss of the Company that is
allocable in respect of such Unitholder’s interest shall be apportioned between
the assignor and the assignee of such Unitholder’s interest using any
permissible method under Code Section 706 and the Regulations thereunder, as
determined by the Management Committee.




(iii)  In the event that any amount claimed by the
Company to constitute a deductible expense in any fiscal year is treated for
federal income tax purposes as a distribution made to a Unitholder in its
capacity as a partner of the Company and not a payment to a Unitholder not
acting in its capacity as a partner under Code Section 707(a), then the
Unitholder who is deemed to have received such distribution shall first be
allocated an amount of Company gross income equal to such payment, its Capital
Account shall be reduced to reflect the distribution, and for purposes of Section 4.3, Net
Income and Net Loss shall be determined after making the allocation required by
this Section
4.3(c)(iii).




(iv)  In the event that any amount claimed by the
Company to constitute a distribution made to a Unitholder in its capacity as a
partner of the Company is treated for federal income tax purposes as a
deductible expense of the Company for a payment to a Unitholder not acting in
its capacity as a partner of the Company, then the Unitholder who is deemed to
have received such payment shall first be allocated the Company expense item
attributable to such payment, its Capital Account shall be reduced to reflect
the allocation, and for purposes of Section 4.3, Net
Income and Net Loss shall be determined after making the allocation required by
this Section
4.3(c)(iv).




(d)  Required Tax
Allocations.  All items of income, gain, loss, deduction and
credit for federal income tax purposes shall be allocated to each Unitholder in
the same manner as the Net Income or Net Loss (and each item of income, gain,
loss and deduction related thereto) that is allocated to such Unitholder
pursuant to Section 4.3(a), (b) and (c) to which such tax items
relate.  Notwithstanding the foregoing provisions of this Section 4.3,
income, gain, loss, deduction, and credits with respect to property contributed
to the Company by a Unitholder shall be allocated among the Unitholders for
federal and state income tax purposes pursuant to Regulations promulgated under
Section 704(c) of the Code, so as to take account of the variation, if any,
between the adjusted basis for federal income tax purposes of the property to
the Company and its initial Gross Asset Value at the time of
contribution.  In the event the Gross Asset Value of any Company asset
is adjusted pursuant to subparagraph (b), (c), or (d) of the definition of Gross
Asset Value, subsequent allocations of income, gain, loss, deduction, and
credits with respect to such asset shall take account of the variation, if any,
between the adjusted basis of such asset for federal income tax purposes and its
Gross Asset Value in the same manner as under Code Section 704(c) and the
applicable Regulations consistent with the requirements of Regulations Section
1.704-1(b)(2)(iv)(g).  Allocations pursuant to this Section 4.3(d) are
solely for purposes of federal, state and local income taxes and shall not
affect, or in any way be taken into account in computing, any Unitholder’s
Capital Account or share of Net Income, Net Loss, other tax items or
distributions pursuant to any provision of this Agreement.




(e)  Unitholders’ Tax
Reporting.  The Unitholders acknowledge and are aware of the
income tax consequences of the allocations made by this Section 4.3 and,
except as may otherwise be required by applicable law or regulatory
requirements, hereby agree to be bound by the provisions of Section 4.3 in
reporting their shares of Company income, gain, loss, deductions, and credits
for federal, state and local income tax purposes.




(f)  Withholding.  Each
Unitholder hereby authorizes the Company to withhold and to pay over any taxes
payable by the Company or any of its Affiliates as a result of the participation
by such Unitholder (or any Assignee of, or Successor in Interest to, such
Unitholder) in the Company.  If and to the extent that the Company
shall be required to withhold any taxes, such Unitholder shall be deemed for all
purposes of this Agreement to have received a payment from the Company as of the
time such withholding is required to be paid, which payment shall be deemed to
be a distribution to such Unitholder under Section 4.4(a) or
Section 5.2 to
the extent that the Unitholder is entitled to receive a distribution and shall
be taken into account in determining the amount of future distributions to such
Unitholder.  To the extent that the aggregate of such payments to a
Unitholder for any period exceeds the distributions to which such Unitholder is
entitled for such period, the amount of such excess shall be considered a demand
loan from the Company to such Unitholder, with interest at an interest rate of
9% compounded annually, which interest shall be treated as an item of Company
income until discharged by such Unitholder by repayment, which may be made in
the sole discretion of the Management Committee out of distributions to which
such Unitholder would otherwise be subsequently entitled.  The
withholdings referred to in this Section 4.3 shall be
made at the maximum applicable statutory rate under applicable tax law unless
the Management Committee receives documentation, satisfactory to the Management
Committee, to the effect that a lower rate is applicable, or that no withholding
is applicable.




SECTION
4.4  Distributions.




(a)  Priority.  Distributable
Assets will be distributed at such time and in such amounts as is determined by
the Management Committee, subject to Sections 4.4(b), (c) and (d) as
follows:




(i)  First, 100% of the
Distributable Assets shall be distributed to the holders of Class D Units in
proportion to each such Unitholder’s Unreturned Class D Capital until each such
Unitholder’s Unreturned Class D Capital has been reduced to zero;




(ii)  Second, after the
required distributions pursuant to subparagraph (i) above, 100% of the
Distributable Assets shall be distributed to the holders of Class D Units in
proportion to each such Unitholder’s Class D Preferred Return until each such
Unitholder’s Class D Preferred Return has been reduced to zero;




(iii)  Third, after the
required distributions pursuant to subparagraph (ii) above, 100% of the
Distributable Assets shall be distributed to the holders of Class A Units and
Class B Units in proportion to each such Unitholder’s Unreturned Class A and
Class B Capital until each such Unitholder’s Unreturned Class A and Class B
Capital has been reduced to zero;




(iv)  Fourth, after the
required distributions pursuant to subparagraph (iii) above, 100% of
Distributable Assets shall be distributed to the holders of Class C-1 Units and
Class C-2 Units that were outstanding but unvested at the time the Company made
one or more previous distributions under Section 4.4(a)(v)
below (and that consequently did not share in such one or more previous
distributions), but that became vested subsequent to such one or more previous
distributions, in an amount and in such proportions between such newly-vested
Class C-1 Units and Class C-2 Units so that the sum of (x) the amount
distributed under this Section 4.4(a)(iv)
plus (y) the aggregate amount distributed in such one or more previous
distributions under Section 4.4(a)(v)
shall be distributed with respect to the Class B Units and vested Class C Units
(including such newly vested Class C-1 Units and Class C-2 Units) in the same
amounts and the same proportions as if such newly-vested Class C-1 Units and
Class C-2 Units had been vested at the time of such one or more previous
distributions (provided that if the Distributable Assets available for
distribution under this Section 4.4(a)(iv)
are insufficient to permit the newly-vested Class C-1 Units and Class C-2 Units
to receive the full amounts to which they would have been entitled if they had
been vested at the time of such one or more previous distributions, the
Distributable Assets shall be shared between the newly-vested Units in the same
proportions as if sufficient Distributable Assets had been
available);




(v)  Fifth, after the
required distributions, if any, pursuant to subparagraph (iv) above, 100% of
Distributable Assets shall be distributed to the holders of Class B Units,
Vested Class C-1 Units and Vested Class C-2 Units, pro rata in accordance with
the number of Class B Units, Vested Class C-1 Units and Vested Class C-2 Units
held by such Unitholder;




provided that, if the
Distributable Assets being distributed consist of more than one kind of asset,
all Distributable Assets consisting of cash must be distributed before any other
kind of asset is distributed; and




provided further
that, the terms of this Section 4.4(a) shall not require the return of any
distributions made in accordance with the terms of the Prior Agreement and
distributions made in accordance with the terms of the Prior Agreement shall be
given effect for purposes of calculating future distributions to be made under
Section 4.4.




(b)  Successors.  For
purposes of determining the amount of distributions under this Section 4.4,
each Unitholder shall be treated as having received amounts received by its
predecessors in respect of any of such Unitholder’s Units.




(c)  Tax
Distributions.  Subject to the Act, no later than the tenth day
of March the Company shall make a tax distribution in cash to each Unitholder in
an amount equal to 110% of the excess of (i) the product of (A) the cumulative
taxable income allocable to such Unitholder (including any guaranteed payments
for services that are not actually received by such Unitholder in cash) in
excess of the cumulative taxable loss allocable to such Unitholder for all
taxable years prior to the year in which such distribution is being made, as
reported on the Unitholder’s Schedule K-1s delivered by the Company to the
Unitholder or (in the case of the taxable year prior to the year in which the
distribution is made, if no Schedule K-1 has yet been delivered with respect to
such year) as estimated in good faith by the Company and (B) the combined
maximum federal, state and local marginal income tax rate (taking into account
the deductibility of state and local taxes and adjusted appropriately to take
into account the varying rates applicable to capital gains, qualified dividend
income and ordinary income) applicable to individual residents of Providence,
Rhode Island, over (ii) all prior distributions pursuant to this Section
4.4.  At the time each tax distribution is made, the Company
shall deliver to each Unitholder a detailed explanation of the manner in which
such tax distribution was calculated, including (if applicable) the Company’s
good faith estimate of the amount of taxable income or loss allocable to the
Unitholder for the taxable year preceding the year in which the distribution was
made.  All tax distributions made to a Unitholder pursuant to this
Section 4.4(c)
on account of the taxable income allocated to such Unitholder shall be treated
as advance distributions under Section 4.4(a) or
Section 5.2 and
shall be taken into account in determining the amount of future distributions to
such Unitholder.




(d)  Requirements for Certain
Distributions.  Other than pursuant to an Exit Event or other
dissolution under Section 5.2, any
distribution of assets other than cash or Marketable Securities pursuant to this
Section 4.4
shall require the approval of (i) all the Representatives constituting the
Management Committee or (ii) THL Holders holding a majority of the Units held by
the THL Holders and Management Holders holding a majority of all Units held by
the Management Holders.  In addition, any distribution of Marketable
Securities pursuant to Section 4.4 prior to
an Exit Event or other dissolution under Section 5.2 shall
only be permitted if each THL Third Party Investment Fund that receives such
distribution (whether such distribution is initially received directly or
indirectly by another THL Holder) distributes to its investors promptly
thereafter its portion of such distribution.




(e)  Valuation.  All
Distributable Assets shall be valued by the Management Committee in good faith,
except as specifically provided in the following sentence with respect to
securities that are publicly traded.  In the case of any distribution
of securities that are publicly traded, such securities shall be valued at the
lesser of (i) the average of the last reported trade price of securities of such
class on the 10 most recent trading days prior to the date of distribution and
(ii) the last reported trade price of securities of such class on the trading
day prior to the date of distribution.




SECTION
4.5  Security Interest and Right
of Set-Off.  As security for any withholding tax or other
liability or obligation to which the Company may be subject as a result of any
act or status of any Unitholder, or to which the Company may become subject with
respect to the interest of any Unitholder, the Company shall have (and each
Unitholder hereby grants to the Company) a security interest in all
Distributable Assets distributable to such Unitholder to the extent of the
amount of such withholding tax or other liability or obligation.  The
Company shall have a right of setoff against such distributions of Distributable
Assets in the amount of such withholding tax or other liability or
obligation.  The Company may withhold distributions or portions
thereof if it is required to do so by the Code or any other provision of
federal, state or local tax or other law.  Any amount withheld
pursuant to the Code or any other provision of federal, state or local tax or
other law with respect to any distribution to a Unitholder shall be treated as
an amount distributed to such Unitholder for all purposes under this
Agreement.

WITHDRAWAL; DISSOLUTION;
TRANSFER OF MEMBERSHIP INTERESTS; ADMISSION OF NEW MEMBERS




SECTION
5.1  Unitholder
Withdrawal.  No Unitholder shall have the power or right to
withdraw or otherwise resign or be expelled from the Company prior to the
dissolution and winding up of the Company except pursuant to a transfer
permitted under this Agreement of all of such Unitholder’s Units to an Assignee,
a Member or the Company.  Notwithstanding anything to the contrary
contained in the Act, in no event shall any Unitholder be deemed to have
withdrawn from the Company or cease to be a Unitholder upon the occurrence of
any of the events specified in this Agreement (other than dissolution pursuant
to Section 5.2), or any events similar thereto, unless the Unitholder, after the
occurrence of any such event, indicates in a written instrument that the
Unitholder has so withdrawn.




SECTION
5.2  Dissolution.




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




(i)  the unanimous vote
of the Management Committee;




(ii)  the written consent
of the holders of a majority of the Units held by the THL Holders and the
holders of a majority of the Units held by the Management Holders;




(iii)  the entry of
a decree of judicial dissolution of the Company under Section 18-802 of the
Act;




(iv)  upon
consummation of an Exit Event, with the consent of a majority of the Management
Committee; and




(v)  upon the
liquidation, dissolution or winding up of the Company or Holdings.




The death,
retirement, resignation, expulsion, incapacity, bankruptcy or dissolution of a
Member, or the occurrence of any other event that terminates the continued
membership of a Member in the Company, shall not cause a dissolution of the
Company, and the Company shall continue in existence subject to the terms and
conditions of this Agreement.




(b)  Actions Upon
Dissolution.  When the Company is dissolved, the business and
property of the Company shall be wound up and liquidated by the Management
Committee or, in the event of the unavailability of the Management Committee,
such Member or other liquidating trustee as shall be named by the Management
Committee.  A reasonable time shall be allowed for the orderly
liquidation of the assets of the Company and the discharge of liabilities to
creditors so as to enable the Members to minimize the normal losses attendant
upon a liquidation.




(c)  Priority.  Following
completion of the wind up and liquidation process, the assets of the Company
shall be distributed in the following manner and order:




(i)  All debts and
obligations of the Company, if any, shall first be paid, discharged or provided
for by adequate reserves in accordance with the Act; and




(ii)  The balance shall
be distributed to the Unitholders in accordance with Section
4.4.




(d)  Cancellation of
Certificate.  On completion of the distribution of Company
assets as provided herein, the Company is terminated, and shall file a
certificate of cancellation with the Secretary of State of the State of
Delaware, cancel any other filings made and take such other actions as may be
necessary to terminate the Company.




(e)  Tax Distribution
Clawback.  Upon dissolution of the Company, to the extent that
(x) any tax distribution received by a Unitholder pursuant to Section 4.4(c) has
not been applied to reduce a distribution to which such Unitholder would
otherwise be entitled under Section 4.4(a) above (an “Unapplied Tax
Distribution”), and (y) such Unitholder recognizes a loss for tax
purposes attributable to such Unitholder’s Units which results in a reduction of
tax or a tax refund or credit (a “Tax Benefit”), such Unitholder shall be
obligated to contribute to the Company an amount of cash equal to the lesser of
the amount of such Unapplied Tax Distribution or such Tax Benefit, such
contribution to be made promptly upon such Unitholder’s receipt of such Tax
Benefit.  In the event that a Unitholder that has received an
Unapplied Tax Distribution contributes less than the full amount of such
Unapplied Tax Distribution to the Company because the Unitholder has not
recognized a Tax Benefit at least equal to such Unapplied Tax Distribution at
the time of the dissolution of the Company, then upon recognition of any Tax
Benefit with respect to any of such Unitholder’s next five tax years (including
the tax year in which the dissolution occurs), which Tax Benefits on a
cumulative basis do not exceed such Unitholder's Unapplied Tax Distribution,
such Unitholder shall pay an amount equal to such Tax Benefit directly to THL
for distribution to the other former Unitholders (or their successors) in the
same proportions that they would have received the proceeds of such distribution
if it had been made at the time of the dissolution of the Company.




SECTION
5.3  Transfer by
Unitholders.  Subject to the restrictions
on  transfer set forth in the Securityholders Agreement and this
Agreement, a Unitholder may transfer or assign all or part of its interest as a
Unitholder in the Company to any Person that agrees in writing to assume the
responsibility of a Unitholder.  Any Member who shall assign any Units
in the Company shall cease to be a Member of the Company with respect to such
Units and shall no longer have any rights or privileges of a Member with respect
to such Units.  Any Member or Assignee who acquires in any manner
whatsoever any Units, irrespective of whether such Person has accepted and
adopted in writing the terms and provisions of this Agreement, shall be deemed
by the acceptance of the benefits of the acquisition thereof to have agreed to
be subject to and bound by all of the terms and conditions of this Agreement
that any predecessor in such Units or other interest in the Company was subject
to or by which such predecessor was bound.  No Member shall cease to
be a Member upon the collateral assignment of, or the pledging or granting of a
security interest in, its entire interest in the Company.




SECTION
5.4  Admission or Substitution of
New Members.




(a)  Admission.  The
Management Committee shall have the right, subject to Section 5.3, to admit
as a Substitute Member or an Additional Member, any Person who acquires an
interest in the Company, or any part thereof, from a Member or from the Company;
provided that, the Management
Committee shall admit as a Substitute Member, subject to Section 5.4(b), any
Permitted Transferee (as such term is defined in the Securityholders Agreement)
who acquires an interest in the Company pursuant to a transfer from a
Member.  Concurrently with the admission of a Substitute Member or an
Additional Member, the Management Committee shall forthwith cause any necessary
papers to be filed and recorded and notice to be given wherever and to the
extent required showing the substitution of a transferee as a Substitute Member
in place of the transferring Member, or the admission of an Additional Member,
all at the expense, including payment of any professional and filing fees
incurred, of the Substitute Member or the Additional Member.




(b)  Conditions.  The
admission of any Person as a Substitute or Additional Member shall be
conditioned upon (i) such Person’s written acceptance and adoption of all the
terms and provisions of this Agreement, either by (X) execution and delivery of
a counterpart signature page to this Agreement countersigned by a an authorized
Officer on behalf of the Company or (Y) any other writing evidencing the intent
of such Person to become a Substitute Member or Additional Member and such
writing is accepted by the Management Committee on behalf of the Company and
(ii) (at the request of the Management Committee) such Person’s execution and
delivery of a counterpart to the Securityholders Agreement.




SECTION
5.5  Compliance with
Law.  Notwithstanding any provision hereof to the contrary, no
sale or other disposition of an interest in the Company may be made except in
compliance with all federal, state and other applicable laws, including federal
and state securities laws.  Nothing in this Section 5.5 shall be
construed to limit or otherwise affect any of the provisions of the
Securityholders Agreement or the Management Unit Subscription Agreements, and to
the extent any such provisions apply, they are then to be construed as being
incorporated in this Agreement and made a part hereof.

REPORTS TO MEMBERS; TAX
MATTERS




SECTION
6.1  Access.  Each
Member shall have access to all books, records and accounts of the Company as is
required under the Act, in each case, under such conditions and restrictions as
the Management Committee may reasonably prescribe.




SECTION
6.2  Reports.




(a)  Tax
Reporting.  The Company shall supply to the Unitholders all
information reasonably necessary to enable each Unitholder to prepare its
federal, state, and local income tax returns, which information shall include a
Schedule K-1.




(b)  Determinations.  All
determinations, valuations and other matters of judgment required to be made for
accounting purposes under this Agreement shall be made by the Management
Committee in good faith and, if so made, shall be conclusive and binding on all
Unitholders, their Successors in Interest and any other Person, and to the
fullest extent permitted by law, no such Person shall have the right to an
accounting or an appraisal of the assets of the Company or any successor
thereto.




SECTION
6.3  Fiscal
Year.  The fiscal year of the Company shall end on December
31st
of each calendar year unless otherwise determined by the Management Committee in
accordance with Section 706 of the Code.




SECTION
6.4  Certain Tax
Matters.




(a)  Preparation of
Returns.  The Management Committee shall cause to be prepared
all federal, state and local tax returns of the Company for each year for which
such returns are required to be filed and shall cause such returns to be timely
filed.  The Management Committee shall determine the appropriate
treatment of each item of income, gain, loss, deduction and credit of the
Company and the accounting methods and conventions under the tax laws of the
United States, the several states and other relevant jurisdictions as to the
treatment of any such item or any other method or procedure related to the
preparation of such tax returns.  The Management Committee may cause
the Company to make or refrain from making any and all elections permitted by
such tax laws.  Each Unitholder agrees that it shall not, except as
otherwise required by applicable law or regulatory requirements, (i) treat, on
its individual income tax returns, any item of income, gain, loss, deduction or
credit relating to its interest in the Company in a manner inconsistent with the
treatment of such item by the Company as reflected on the Form K-1 or other
information statement furnished by the Company to such Unitholder for use in
preparing its income tax returns or (ii) file any claim for refund relating to
any such item based on, or which would result in, such inconsistent
treatment.  In respect of an income tax audit of any tax return of the
Company, the filing of any amended return or claim for refund in connection with
any item of income, gain, loss, deduction or credit reflected on any tax return
of the Company, or any administrative or judicial proceedings arising out of or
in connection with any such audit, amended return, claim for refund or denial of
such claim, (A) the Tax Matters Member (as defined below) shall be authorized to
act for, and its decision shall be final and binding upon, the Company and all
Unitholders except to the extent a Unitholder shall properly elect to be
excluded from such proceeding pursuant to the Code, (B) all expenses incurred by
the Tax Matters Member in connection therewith (including attorneys’,
accountants’ and other experts’ fees and disbursements) shall be expenses of,
and payable by, the Company, (C) no Unitholder shall have the right to (1)
participate in the audit of any Company tax return, (2) file any amended return
or claim for refund in connection with any item of income, gain, loss, deduction
or credit (other than items which are not partnership items within the meaning
of Section 6231(a)(4) of the Code or which cease to be partnership items under
Section 6231(b) of the Code) reflected on any tax return of the Company, (3)
participate in any administrative or judicial proceedings conducted by the
Company or the Tax Matters Member arising out of or in connection with any such
audit, amended return, claim for refund or denial of such claim, or (4) appeal,
challenge or otherwise protest any adverse findings in any such audit conducted
by the Company or the Tax Matters Member or with respect to any such amended
return or claim for refund filed by the Company or the Tax Matters Member or in
any such administrative or judicial proceedings conducted by the Company or the
Tax Matters Member and (D) the Tax Matters Member shall keep the Unitholders
reasonably apprised of the status of any such
proceeding.  Notwithstanding the previous sentence, if a petition for
a readjustment to any partnership item included in a final partnership
administrative adjustment is filed with a District Court or the Court of Claims
and the IRS has elected to assess income tax against a Member with respect to
that final partnership administrative adjustments (rather than suspending
assessments until the District Court or Court of Claims proceedings become
final), such Member shall be permitted to file a claim for refund within such
period of time to avoid application of any statute of limitation provisions
which would otherwise prevent the Member from having any claim based on the
final outcome of that review.




(b)  Tax Matters
Member.  The Company and each Member hereby designate Thomas H.
Lee Equity Fund V, L.P. as the “tax matters partner” for purposes of Section
6231(a)(7) of the Code (the “Tax Matters
Member”).




(c)  Certain
Filings.  Upon the sale of Company assets or a liquidation of
the Company, Unitholders shall provide the Management Committee with certain tax
filings as reasonably requested by the Management Committee and required under
applicable law.

MISCELLANEOUS




SECTION
7.1  Schedules.  Without
in any way limiting the provisions of Section 6.2, a Representative may from
time to time execute on behalf of the Company and deliver to the Unitholders
schedules which set forth the then current Capital Account balances of each
Unitholder and any other matters deemed appropriate by the Management Committee
