          and any items in the nature of income or gains which are specially
          allocated to such Member pursuant to Section 5.2 or Section 5.3, and
          the amount of any liabilities of the Company assumed by such Member or
          which are secured by any property distributed to such Member.

               (ii) Such Capital Account shall be decreased by the cash amount
          or Book Value of any property distributed to such Member pursuant to
          this Agreement, such Member's allocable share of Losses and any items
          of in the nature of deductions or losses which are specially allocated
          to such Member pursuant to Section 5.2 or Section 5.3, and the amount
          of any liabilities of such Member assumed by the Company or which are
          secured by any property contributed by such Member to the Company.

               (iii)  If all or any portion of a Membership Interest is
          Transferred in accordance with the terms of this Agreement, the
          transferee shall succeed to the Capital Account, the Contributed
          Capital Account and the Pro Rata Percentages of the transferor to the
          extent it relates to the transferred Membership Interest.

               (iv) If a new or existing Member contributed money or property to
          the Company (other than a de minimis amount as determined by the
          Board) as consideration for the issuance by the Company of any Units
          after the date hereof, the Capital Accounts of the Members shall be
          adjusted in accordance with Treasury Regulation Section 1.704-
          1(b)(2)(iv)(f).

The foregoing provisions and the other provisions of this Agreement relating to
the maintenance of Capital Accounts are intended to comply with Section 1.704-
1(b) of the Treasury Regulations and shall be interpreted and applied in a
manner consistent with such Treasury Regulations.  If the President or Secretary
of the Company determines that it is prudent to modify the manner in which the
Capital Accounts, or any increases or decreases to the Capital Accounts, are
computed in order to comply with such Treasury Regulations, the President or
Secretary of the Company may authorize such modifications.

          (b) Definition of Profits and Losses. "Profits" and "Losses" mean,
for each Taxable Year or other period, an amount equal to the Company's taxable
income or loss for such Taxable Year or other period, determined in accordance
with Code Section 703(a) (for this purpose, all items of income, gain, loss or
deduction required to be stated separately pursuant to Code Section 703(a)(1)
shall be included in taxable income or loss), with the following adjustments:

                  (i) The computation of all items of income, gain, loss and
          deduction shall include tax-exempt income and those items described in
          Treasury Regulation

                                      -8-
<PAGE>

          Section 1.704-1(b)(2)(iv)(i), without regard to the fact that such
          items are not includable in gross income or are not deductible for
          federal income tax purposes.

                  (ii) If the Book Value of any Company property is adjusted
          pursuant to Treasury Regulation Section 1.704-1(b)(2)(iv)(e) or (f),
          the amount of such adjustment shall be taken into account as gain or
          loss from the disposition of such property.

                  (iii)  Items of income, gain, loss or deduction attributable
          to the disposition of Company property having a Book Value that
          differs from its adjusted basis for tax purposes shall be computed by
          reference to the Book Value of such property.

                  (iv) Items of depreciation, amortization and other cost
          recovery deductions with respect to Company property having a Book
          Value that differs from its adjusted basis for tax purposes shall be
          computed by reference to the property's Book Value in accordance with
          Treasury Regulation Section 1.704-1(b)(2)(iv)(g).

                  (v) To the extent an adjustment to the adjusted tax basis of
          any Company property pursuant to Code Sections 732(d), 734(b) or
          743(b) is required, pursuant to Treasury Regulation Section 1.704-
          1(b)(2)(iv)(m), to be taken into account in determining Capital
          Accounts, the amount of such adjustment to the Capital Accounts shall
          be treated as an item of gain (if the adjustment increases the basis
          of the asset) or loss (if the adjustment decreases such basis).

     4.3  Negative Capital Accounts. If any Member has a deficit balance in
its Capital Account, such Member shall have no obligation to restore such
negative balance or to make any Capital Contributions to the Company by reason
thereof, and such negative balance shall not be considered an asset of the
Company or of any Member.

     4.4  No Withdrawal. No Member shall be entitled to withdraw any part of
its Capital Contribution or Capital Account or to receive any distribution from
the Company, except as expressly provided herein.

     4.5  Loans From Members. Loans by Members to the Company shall not be
considered Capital Contributions.

     4.6  Status of Capital Contributions.

          (a) No Member shall receive any interest, salary or drawing with
respect to its Capital Contributions or its Capital Account, except as otherwise
specifically provided in this Agreement.

          (b) Except as otherwise provided herein and by applicable state law,
the Members shall be liable only to make their Capital Contributions pursuant to
Section 4.1(a) hereof, and no Member shall be required to lend any funds to the
Company or, after a Member's Capital Contributions have been fully paid pursuant
to Section 4.1(a) hereof, to make any additional Capital

                                      -9-
<PAGE>

Contributions to the Company. No Member shall have any personal liability for
the repayment of any Capital Contribution of any other Member.


                                    ARTICLE 5

                        ALLOCATIONS OF PROFITS AND LOSSES

     5.1  Allocation of Profits and Losses.

          (a) Allocation of Profits. After giving effect to the allocations set
forth in Section 5.2 and Section 5.3, Profits for any Taxable Year (or other
period) shall be allocated to holders of Common Units pro rata according to
their Pro Rata Percentages.

          (b) Allocation of Losses. After giving effect to the allocations set
forth in Section 5.2 and Section 5.3, Losses for any Taxable Year (or other
period) shall be allocated to the holders of Common Units pro rata according to
their Pro Rata Percentages.

     5.2  Regulatory and Special Allocations. Notwithstanding the provisions
of Section 5.1:

          (a) To the extent an adjustment to the adjusted tax basis of any
Company asset pursuant to Code Section 734(b) or 743(b) is required to be taken
into account in determining Capital Accounts, the amount of such adjustment to
the Capital Accounts shall be treated, as provided in Treasury Regulation
Section 1.704-1(b)(2)(iv)(m), as an item of Profits (if the adjustment increases
the basis of the asset) or Losses (if the adjustment decreases such basis) and
such Profits or Losses shall be specially allocated to the Members in a manner
consistent with the manner in which their Capital Accounts are required to be
adjusted pursuant to such Section of the Treasury Regulations.

          (b) If there is a net decrease in Company Minimum Gain (determined
according to Treasury Regulation Section 1.704-2(d)(1)) during any Taxable Year,
each Member shall be specially allocated Profits for such Taxable Year (and, if
necessary, subsequent Taxable Years) in an amount equal to such Member's share
of the net decrease in Company Minimum Gain, determined in accordance with
Treasury Regulation Section 1.704-2(g).  The items to be so allocated shall be
determined in accordance with Treasury Regulation Sections 1.704-2(f)(6) and
1.704-2(j)(2).  This paragraph is intended to comply with the minimum gain
chargeback requirement in Treasury Regulation Section 1.704-2(f) and shall be
interpreted consistently therewith.

          (c) Member Nonrecourse Deductions shall be allocated in the manner
required by Treasury Regulation Section 1.704-2(i).  Except as otherwise
provided in Treasury Regulation Section 1.704-2(i)(4), if there is a net
decrease in Member Minimum Gain during any Taxable Year, each Member that has a
share of such Member Minimum Gain shall be specially allocated Profits for such
Taxable Year (and, if necessary, subsequent Taxable Years) in an amount equal to
that Member's share of the net decrease in Member Minimum Gain.  Items to be
allocated pursuant to this paragraph shall be determined in accordance with
Treasury Regulation Sections 1.704-2(i)(4) and 1.704-2(j)(2).  This paragraph is
intended to comply with the minimum gain chargeback requirements in Treasury
Regulation Section 1.704-2(i)(4) and shall be interpreted consistently
therewith.

                                      -10-
<PAGE>

          (d) In the event any Member unexpectedly receives any adjustments,
allocations or distributions described in Treasury Regulation Section 1.704-
1(b)(2)(ii)(d)(4), (5) or (6), Profits shall be specially allocated to such
Member in an amount and manner sufficient to eliminate the Adjusted Capital
Account Deficit created by such adjustments, allocations or distributions as
quickly as possible.  This paragraph is intended to comply with the qualified
income offset requirement in Treasury Regulation Section 1.704-1(b)(2)(ii)(d)
and shall be interpreted consistently therewith.

          (e) The allocations set forth in paragraphs (a), (b), (c) and (d)
above (the "Regulatory Allocations") are intended to comply with certain
requirements of the Treasury Regulations under Code Section 704.
Notwithstanding any other provisions of this Article 5 (other than the
Regulatory Allocations), the Regulatory Allocations shall be taken into account
in allocating Profits and Losses among Members so that, to the extent possible,
the net amount of such allocations of Profits and Losses and other items and the
Regulatory Allocations to each Member shall be equal to the net amount that
would have been allocated to such Member if the Regulatory Allocations had not
occurred.

     5.3  Curative Allocations. If the President or Secretary of the Company
determines, after consultation with counsel experienced in income tax matters,
that the allocation of any item of Company income, gain, loss, deduction or
credit is not specified in this Article 5 (an "unallocated item"), or that the
allocation of any item of Company income, gain, loss, deduction or credit
hereunder is clearly inconsistent with the Members' economic interests in the
Company (determined by reference to the general principles of Treasury
Regulation Section 1.704-1(b) and the factors set forth in Treasury Regulation
Section 1.704-1(b)(3)(ii)) (a "misallocated item"), then the President or
Secretary of the Company may allocate such unallocated items, or reallocate such
misallocated items, to reflect such economic interests; provided that no such
allocation will be made without the prior consent of each Member that would be
affected thereby (which consent no such Member may unreasonably withhold) and
provided further that no such allocation shall have any material effect on the
amounts distributable to any Member, including the amounts to be distributed
upon the complete liquidation of the Company.

     5.4  Tax Allocations.

          (a) All income, gains, losses, deductions and credits of the Company
shall be allocated, for federal, state and local income tax purposes, among the
Members in accordance with the allocation of such income, gains, losses,
deductions and credits among the Members for computing their Capital Accounts,
except that if any such allocation for tax purposes is not permitted by the Code
or other applicable law, the Company's subsequent income, gains, losses,
deductions and credits shall be allocated among the Members for tax purposes, to
the extent permitted by the Code and other applicable law, so as to reflect as
nearly as possible the allocation set forth herein in computing their Capital
Accounts.

          (b) Items of Company taxable income, gain, loss and deduction with
respect to any property contributed to the capital of the Company shall be
allocated among the Members in accordance with Code Section 704(c) and the
traditional method of Treasury Regulation Section 1.704-3(b) so as to take
account of any variation between the adjusted basis of such property to the
Company for federal income tax purposes and its Book Value.

                                      -11-
<PAGE>

          (c) If the Book Value of any Company property is adjusted pursuant to
Section 4.2, subsequent allocations of items of taxable income, gain, loss and
deduction with respect to such property shall take account of any variation
between the adjusted basis of such property for federal income tax purposes and
its Book Value in the same manner as under Code Section 704(c).

          (d) Allocations of tax credit, tax credit recapture, and any items
related thereto shall be allocated to the Members according to their interests
in such items as determined by the President or Secretary of the Company taking
into account the principles of Treasury Regulation Section 1.704-1(b)(4)(ii).

          (e) Allocations pursuant to this Section 5.4 are solely for purposes
of federal, state and local taxes and shall not affect, or in any way be taken
into account in computing, any Member's Capital Account or share of Profits,
Losses, distributions or other items pursuant to any provisions of this
Agreement.


                                    ARTICLE 6

                                  DISTRIBUTIONS

     6.1  Generally.

          (a) Subject to Section 6.2, the President of the Company shall have
sole discretion regarding the amounts and timing of distributions to Members, in
each case subject to the retention and establishment of reserves of, or payment
to third parties of, such funds as it deems necessary with respect to the
reasonable business needs of the Company which shall include the payment or the
making of provision for the payment when due of the Company's obligations,
including the payment of any management or administrative fees and expenses or
any other obligations.

          (b) Notwithstanding any provision to the contrary contained in this
Agreement, the Company shall not make any distribution to Members if such
distribution would violate Section 18-607 of the Delaware Act or other
applicable law.

     6.2  Distributions. Distributions to be made by the Company on any date
shall be made to the holders of Common Units pro rata according to their Pro
Rata Percentages.


                                    ARTICLE 7

                            MANAGEMENT OF THE COMPANY

appoint individuals as officers ("officers") of the Company, which shall include

                                      -12-
<PAGE>

Secretary and (iii) such other officers (such as any number of Vice Presidents)
as a Majority in Interest of the Members deems advisable. Management and control
of the Company is hereby delegated to the officers, who shall conduct, direct,
and exercise full control over all activities of the Company as provided herein;
provided that all officers other than the President shall report to and shall be
under the direction of the President. An individual can be appointed to more
than one office. Each officer shall be a "manager" (as that term is defined in
the Delaware Act) of the Company.

          (b) Appointment. Effective as of the date hereof, the Majority in
Interest of the Members hereby appoint (i) Michael Krupka as President of the
Company and (ii) Michael Krupka as Secretary of the Company, in each case, until
their successors have been duly appointed and qualified, or until their earlier
death, resignation or removal in accordance with the terms of this Agreement.

          (c) Powers. The business and affairs of the Company shall be managed
by or under the direction of the President of the Company and the other
officers.

          (d) Authority of Officers. Any officer of the Company shall have the
right, power and authority to transact business in the name of the Company or to
act for or on behalf of or to bind the Company.  Third parties dealing with the
Company may rely conclusively upon any certificate of any officer to the effect
that such officer is acting on behalf of the Company.

          (e) Removal, Resignation and Filling of Vacancy of Officers. A
Majority in Interest of the Members may remove any officer, for any reason or
for no reason, at any time.  Any officer may resign at any time by giving
written notice to the Members, and such resignation shall take effect at the
date of the receipt of that notice or any later time specified in that notice;
provided, that unless otherwise specified in that notice, the acceptance of the
resignation shall not be necessary to make it effective.  Any such resignation
shall be without prejudice to the rights, if any, of the Company or such officer
under this Agreement.  A vacancy in any office because of death, resignation,
removal or otherwise shall be filled in the manner prescribed in this Agreement
for regular appointments to that office.

          (f) Compensation of Officers. No officer shall be entitled to receive
compensation from the Company for performing its duties as an officer under this
Agreement.

          (g) President. The President shall manage the business and affairs of
the Company.

          (h) Secretary. The Secretary shall (i) be custodian of the company
records; (ii) keep a register of the addresses of each Member which shall be
furnished to the Secretary by such Member; (iii) have general charge of the
Members Schedule; and (iv) in general perform all duties incident to the office
of a secretary of a company.  The Secretary shall have such other powers and
perform such other duties as are provided in this Agreement and as may from time
to time be prescribed by the President.

     7.2  Performance of Duties; Liability of Officers. In performing his or
her duties, each of the officers shall be entitled to rely in good faith on the
provisions of this Agreement and on

                                      -13-
<PAGE>

information, opinions, reports, or statements (including financial statements
and information, opinions, reports or statements as to the value or amount of
the assets, liabilities, profits or losses of the Company or any facts pertinent
to the existence and amount of assets from which distributions to Members might
properly be paid), of the following other Persons or groups: (a) one or more of
the other officers or employees of the Company; (b) any attorney, independent
accountant, or other Person employed or engaged by the Company; or (c) any other
Person who has been selected with reasonable care by or on behalf of the
Company, in each case as to matters which such relying Person reasonably
believes to be within such other Person's professional or expert competence. The
preceding sentence shall in no way limit any Person's right to rely on
information to the extent provided in Section 18-406 of the Delaware Act. No
individual who is an officer of the Company shall be personally liable under any
judgment of a court, or in any other manner, for any debt, obligation, or
liability of the Company, whether that liability or obligation arises in
contract, tort, or otherwise, solely by reason of being an officer of the
Company.

     7.3  Indemnification. The officers shall not be liable, responsible or
accountable for damages or otherwise to the Company, or to the Members, and, to
the fullest extent allowed by law, each officer shall be indemnified and held
harmless by the Company, including advancement of reasonable attorneys' fees and
other expenses, but only to the extent that the Company's assets are sufficient
therefor, from and against all claims, liabilities, and expenses arising out of
any management of Company affairs; provided that (a) such officer's course of
conduct was pursued in good faith and believed by him to be in the best
interests of the Company and (b) such course of conduct did not constitute gross
negligence or willful misconduct on the part of such officer and otherwise was
in accordance with the terms of this Agreement.  The rights of indemnification
provided in this Section 7.3 are intended to provide indemnification of the
officers to the fullest extent permitted by Delaware General Corporation Law
regarding a corporation's indemnification of its directors and officers and will
be in addition to any rights to which the officer may otherwise be entitled by
contract or as a matter of law and shall extend to his heirs, personal
representatives and assigns.  The absence of any express provision for
indemnification herein shall not limit any right of indemnification existing
independently of this Section 7.3.  Each officer's right to indemnification
pursuant to this Section 7.3 may be conditioned upon the delivery by such
officer of a written undertaking to repay such amount if such individual is
determined pursuant to this Section 7.3 or adjudicated to be ineligible for
indemnification, which undertaking shall be an unlimited general obligation.


                                    ARTICLE 8

have the power to act for or on behalf of, or to bind the Company.

                        TRANSFER OF MEMBERSHIP INTERESTS

     9.1  Restrictions. Each Member acknowledges and agrees that such Member
shall not Transfer any Membership Interest(s) except in accordance with the
provisions of this Article 9.  Any attempted Transfer in violation of the
preceding sentence shall be deemed null and void for all purposes, and the
Company will not record any such Transfer on its books or treat any purported
transferee as the owner of such Membership Interest(s) for any purpose.

     9.2  General Restrictions on Transfer.

          (a) Notwithstanding anything to the contrary in this Agreement, no
transferee of any Membership Interest(s) received pursuant to a Transfer (but
excluding transferees that were Members immediately prior to such a Transfer)
shall become a Member in respect of or be deemed to have any ownership rights in
the Membership Interest(s) so Transferred unless a Person is admitted as a
Member as set forth in Section 9.3(a).

          (b) Following a Transfer of any Membership Interest(s) that is
permitted under this Article 9, the transferee of such Membership Interest(s)
shall succeed to the Capital Account, Contributed Capital Account and the Pro
Rata Percentages associated with such Membership Interest(s) and shall receive
allocations and distributions under Articles 4, 5, 6 and 10 in respect of such
Membership Interest(s).

          (c) Any Member who Transfers all of his or its Membership Interests
(i) shall cease to be a Member upon such Transfer, and (ii) shall no longer
possess or have the power to exercise any rights or powers of a Member of the
Company.

          (d) Notwithstanding anything contained herein to the contrary, no
Member may Transfer any Membership Interest(s) without the prior written consent
of the President of the Company (provided that the President of the Company
shall be deemed to have given his prior written consent to any Transfer of
Membership Interest(s) by any Member pursuant to the Sealy Credit Agreement).

     9.3  Procedure for Transfers. Subject in all events to the general
restrictions on Transfers contained in Sections 9.1 and 9.2, a Member may
Transfer all or any part of his or its Membership Interests in accordance with
this Section 9.3.

                                      -15-
<PAGE>

          (a) No Transfer of Membership Interest(s) may be completed until the
prospective transferee is admitted as a Member of the Company by executing and
delivering to the Secretary of the Company a written undertaking to be bound by
the terms and conditions of this Agreement substantially in the form of Exhibit
A hereto.  Upon the amendment of the Members Schedule by the Secretary of the
Company and the satisfaction of any other applicable conditions, such
prospective transferee shall be admitted as a Member and deemed listed as such
on the books and records of the Company.

          (b) Unless waived by the President or Secretary of the Company, no
Member may Transfer any Membership Interests (except pursuant to an effective
registration statement under the Securities Act) without first delivering to the
Company an opinion of counsel reasonably acceptable in form and substance to the
Company (which counsel will be reasonably acceptable to the Company) that
registration under the Securities Act is not required in connection with such
Transfer.

     9.4  Limitations.

          (a) Notwithstanding anything to the contrary in this Agreement, no
Membership Interest may be Transferred if such Transfer would result in the
Company having more than 100 "beneficial owners" as defined and determined by
the Investment Company Act of 1940, as amended from time to time.

          (b) In order to permit the Company to qualify for the benefit of a
"safe harbor" under Code Section 7704, notwithstanding anything to the contrary
in this Agreement, no Transfer of any Membership Interest shall be permitted or
recognized by the Company (within the meaning of Treasury Regulation Section
1.7704-1(d)) if and to the extent that such Transfer would cause the Company to
have more than 100 partners (within the meaning of Treasury Regulation Section
1.7704-1(h), including the look-through rule in Treasury Regulation Section
1.7704-1(h)(3)).

the Members.  The Liquidator shall agree not to resign at any time without 30
days prior written notice.  Except as expressly provided in this Article 10, the
Liquidator appointed in the manner provided herein shall have and may exercise,
without further authorization or consent of any of the parties hereto, all of
the powers conferred upon the officer of the Company under the terms of this
Agreement (but subject to all of the applicable limitations, contractual and
otherwise, upon the exercise of such powers) to the extent necessary or
desirable in the good faith judgment of the Liquidator to carry out the duties
and functions of the Liquidator hereunder for and during such period of time as
shall be reasonably required in the good faith judgment of the Liquidator to
complete the winding up and liquidation of the Company as provided for herein.

          (b) The Liquidator shall liquidate the assets of the Company, and
apply and distribute the proceeds of such liquidation, in the following order of
priority, unless otherwise required by mandatory provisions of applicable law:

                  (i) the payment to the creditors of the Company, including
          Members, in order of priority as provided by law;

                  (ii) to establish or add to such reserves as the Liquidator
          may deem necessary or appropriate; and

                  (iii)  to the Members as provided in Section 6.2.

The reserves established pursuant to subparagraph (ii) shall be paid over by the
Liquidator to a bank or other financial institution, to be held in escrow for
the purpose of paying any contingent or unforeseen liabilities or obligations
and, at the expiration of such period as the Liquidator deems advisable, such
reserves shall be distributed to the Members in the priorities set forth in this
Section 10.2(b).

          (c) The Members shall not be responsible for restoring any negative
balance in their Capital Accounts upon termination or dissolution of the
Company.

          (d) In any termination or dissolution of the Company, the Company may
distribute the assets of the Company to Members in cash, ratably in kind or any
combination thereof.  Each distribution in kind of property pursuant to Section
10.2(b)(iii) shall be distributed based upon the fair market value of such
property.  If a Liquidating Distribution is made both in cash and in kind, such
Liquidating Distribution shall be made so that, to the fullest extent
practicable, the percentage of cash and any other assets distributed to each
Member is identical.

          (e) Distributions upon liquidation of the Company (or any Member's
interest in the Company) and related adjustments shall be made by the end of the
Taxable Year of the liquidation (or, if later, within ninety (90) days after the
date of such liquidation) or as otherwise permitted by Treasury Regulation
Section 1.704-1(b)(2)(ii)(b), including requirements (2) and (3) thereof.

          (f) Upon completion of the distribution of the assets of the Company
as provided in Section 10.2(b) hereof, the Company shall be terminated and the
Liquidator shall cause the cancellation of the Certificate in the State of
Delaware and of all qualifications and registrations of the Company as a foreign
limited liability company in jurisdictions other than the State of Delaware and
shall take such other actions as may be necessary to terminate the Company.

          (g) Each Member hereby waives any rights to partition of the assets of
the Company.
