"Board") comprised of natural persons (the "Directors") having the authority and
 -----                                      ---------
duties set forth in this Agreement. Each Director shall be designated as either
a "Class A Director" or a "Class B Director". Each Class A Director shall be
   ----------------        ----------------
entitled to three votes and each Class B Director shall be entitled to one vote.
Any decisions to be made by the Board shall require the approval of a Majority
of the Board. Except as provided in the immediately preceding sentence, no
Director acting alone, or with any other Director or Directors, shall have the
power to act for or on behalf of, or to bind the Company. Each Director shall be
a "manager" (as that term is defined in the Delaware Act) of the Company, but,
notwithstanding the foregoing, no Director shall have any rights or powers
beyond the rights and powers granted to such Director in this Agreement.
Directors need not be residents of the State of Delaware.

          (b) Powers. The business and affairs of the Company shall be managed
              ------

class of Directors shall, as of the date hereof, be three Class A Directors and
five Class B Directors and, hereafter, the authorized number of each class of
Directors may be increased or decreased by the Board; provided, that, so long as
                                                      --------
any Series A Preferred Units are outstanding, during the continuation of any
Class A Default (as such term is defined in the Securities Purchase Agreement),
the authorized number of Class A Directors shall be increased by two to five and
such additional Class A Directors shall be elected, and, during the continuation
of any Class B Default (as such term is defined in the Securities Purchase
Agreement) at any time when no Class A Default is continuing, the authorized
number of Class B Directors shall be increased by two to seven and such
additional Class B Directors shall be elected, in each case in accordance with
the terms of Section 2(a)(iv) of the Securityholders Agreement. Each Director
shall be elected by vote of a Majority in Voting Interest or as otherwise
provided in the Members Agreement or the Securityholders Agreement and shall
hold office until his or her successor is elected and qualified or until his or
her earlier death, resignation or removal.

                    (i) Subject to the terms and provisions of the
          Securityholders Agreement, a Majority in Voting Interest may remove,
          for or without cause, any Director and fill the resulting vacancy;
          provided, that whenever any Director shall have been elected by a
          --------
          particular Member or Members pursuant to the Securityholders
          Agreement, such Director may be removed and the vacancy filled only by
          such Member or Members entitled to designate such Director as set
          forth in the Securityholders Agreement.

                    (ii) A Director may resign at any time by giving written
          notice to the Board. Any such resignation shall take effect at the
          time of the receipt of such notice or any later effective time
          specified in such notice; and, unless otherwise specified in such
          notice, the acceptance of the resignation shall not be necessary to
          make such resignation effective. Any vacancy caused by any such
          resignation or by the death of any Director or

                                      -13-

<PAGE>

          for any other reason (including due to the authorization by the Board
          of a newly created directorship) other than due to any removal
          pursuant to Section 3.1(c)(i) may be filled by a Majority in Voting
          Interest; provided, that whenever any vacancy relates to a Director
          that has been elected by a particular Member or Members pursuant to
          the Securityholders Agreement, such vacancy may be filled only by such
          Member or Members, to the extent such Member or Members are then
          entitled to designate such a Director as set forth in the
          Securityholders Agreement.

          (d) Meetings of the Board. The Board shall meet at such time and at

designate; provided, that the Board shall meet not less than two times in any
           --------
twelve month period. Meetings of the Board shall be held on the call of any two
Directors upon at least four Business Days (if the meeting is to be held in
person) or two Business Days (if the meeting is to be held telephonically) by
oral or written notice to the Directors, or upon such shorter notice as may be
approved by all of the Directors. Any Director may waive such notice as to
himself. A record shall be maintained by the Secretary of the Company of each
meeting of the Board.

          Board, a quorum of the Board must be present at such meeting. If a
          quorum shall not be present at any meeting of the Board, then the
          Directors present at the meeting may adjourn the meeting, without
          notice other than announcement at the meeting, until a quorum shall be
          present. A Director may vote or be present at a meeting either in
          person or by proxy. Except as otherwise provided herein or required by
          applicable law, resolutions of the Board at any meeting of the Board
          shall be adopted by the affirmative vote of a Majority of the Board.

                    (iii) Attendance and Waiver of Notice. Attendance of a
                          -------------------------------
          Director at any meeting shall constitute a waiver of notice of such
          meeting, except where a Director attends a meeting for the express
          purpose of objecting to the transaction of any business on the ground
          that the meeting is not lawfully called or convened. Neither the
          business to be transacted at, nor the purpose of, any regular or
          special meeting of the Board need be specified in the notice or waiver
          of notice of such meeting.

                    (iv) Actions Without a Meeting. Notwithstanding any
                         -------------------------
          provision contained in this Agreement, any action of the Board may be
          taken by written consent without a meeting. Any such action taken by
          the Board without a meeting shall be effective only if the written
          consent or consents are in writing, set forth the action so taken and
          are signed by a Majority of the Board, or such greater number of the
          Directors that would be necessary to take such action at a validly
          constituted meeting of the Board.

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

compensation for their services as may be from time to time agreed upon by a
Majority in Voting Interest. In addition, a fixed sum and expenses of
attendance, if any, may be allowed for attendance at each regular or special
meeting of the Board; provided, that nothing contained in this Agreement shall
be construed to preclude any Director from serving the Company or any of its
Subsidiaries in any other capacity and receiving compensation for such service.

          (g) Chairman of the Board. A Majority of the Board may elect any one
              ---------------------
of the Directors to be the Chairman of the Board (the "Chairman"). At any time,
                                                       --------
the Chairman, if any, may be removed from his or her position as Chairman by a

(including financial statements and information, opinions, reports or statements

Distributions to Members might properly be paid) of the following other Persons
or groups: (a) one or more 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

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 a Director or an officer of the Company, or any

Company, or to the Members; and, to the fullest extent allowed by law, each

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 Director's or officer's course of
conduct was pursued in good faith and believed by him to be in the best
interests of the Company and was reasonably believed by him to be within the
scope of authority conferred on such Director or officer pursuant to this
Agreement and (b) such course of conduct did not constitute gross negligence or
willful misconduct on the part of such Director or officer and otherwise was in
accordance with the terms of this Agreement. The rights of indemnification
provided in this Section 3.6 are intended to provide indemnification of the

Corporation Law regarding a corporation's indemnification of its directors and
officers and will be in addition to any rights to which the Directors or officer
may otherwise be entitled by contract or as a matter of law and shall extend to
their respective 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 3.6. Each Director's and
each officer's right to indemnification pursuant to this Section 3.6 may be
conditioned upon the delivery by such Director or such officer of a written
undertaking to repay such amount if such individual is determined pursuant to

undertaking shall be an unlimited general obligation.

    ---------

conferred by this Agreement and any applicable Certificate of Designation.
Ownership of a Unit (or fraction thereof) shall not entitle a Member to call for
a partition or division of any property of the Company or for any accounting.

5.3 Unit Certificates.
    -----------------

          (a) All Units shall be represented by certificates. Each such
certificate shall be signed by an officer of the Company, certifying the number
of Units owned by the holder of such Units and stating the type, class and/or
series of such Units. All certificates for each type and class or series of
Units shall be consecutively numbered or otherwise identified. The name of the
Person to whom the Units represented thereby are issued, the number, type and
class or series of Units and date of issue, shall be entered on the books of the
Company and, until such Units are transferred on the books of the Company
(including the Members Schedule), such Person shall be deemed to be the owner of
such Units for all purposes. Units shall only be transferred on the books of the
Company (including the Members Schedule) by the holder of record thereof, or by
such holder's attorney duly authorized in writing, upon surrender to the Company
of the certificate(s) for such Units endorsed by the appropriate Person(s), with
such evidence of the authenticity of such endorsement, transfer, authorization
and other matters as the Company may reasonably require, and accompanied by all
necessary transfer stamps. If all conditions to such a transfer have been met,
it shall be the duty of the Company to issue a new certificate to the Person
entitled thereto, cancel the old certificate(s), and record the transaction on
its books (including the Members Schedule).

          (b) Any officer of the Company may direct a new certificate(s) to be
issued in place of any certificate(s) previously issued by the Company alleged
to have been lost, stolen or destroyed, upon the making of an affidavit of that
fact by the Person claiming the certificate to be lost, stolen or destroyed.
When authorizing such issuance of a new certificate(s), such officer may, in his
or her discretion and as a condition precedent to the issuance of such new
certificate(s), require the owner of such lost, stolen or destroyed
certificate(s), or his or her legal representative, to give the Company a bond
sufficient to indemnify the Company against any claim that may be made against
the Company on account of such loss, theft or destruction or of the issuance of
such new certificate.

5.4 Issuance of Units. Subject to Section 5.6 and to the limitations contained
    -----------------
in Section 11.5 hereof, the Company (with the approval of the Board) shall have
the right to issue any authorized but unissued Units; provided, that the Company
                                                      --------
shall not issue any Units to any Person unless such Person has executed and
delivered to the Secretary of the Company the documents described in Section 5.5
hereof. Upon the issuance of Units, the Board shall adjust the Capital Accounts
of the Members as necessary in accordance with Section 6.2.

5.5 New Members from the Issuance of Units. In order for a Person to be admitted
    --------------------------------------
as a Member of the Company pursuant to the issuance of Units to such Person,
such Person shall have executed and delivered 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 C hereto (each, a "Joinder"). Upon
                             ---------                  -------
execution of a Joinder, the amendment of the Members Schedule by the Secretary
of the Company and the satisfaction of any other applicable conditions,
including the receipt by the Company of payment for the issuance of the
applicable Units, such Person shall be admitted as a Member and deemed listed as
such on the books and records of the Company and thereupon shall be issued his
or its Units. The Board shall then adjust the Capital Accounts of the Members as
necessary in accordance with Section 6.2.

                                      -22-

5.6 Class B-4 Units.
    ---------------

          (a) Mandatory Issuances of Class B-4 Units. If the Company shall
              --------------------------------------
declare a dividend or make a Distribution on any of its outstanding Common Units
in Common Units, or subdivide or reclassify any of its outstanding Common Units
into a greater number of Common Units (other than any dividend, Distribution,
subdivision or reclassification equally applicable to all Common Units), the
number of Class B-4 Units held by any Member at the time of the effective date
of or record date for such dividend, Distribution, subdivision or
reclassification shall be adjusted so that it shall equal the number of Class
B-4 Units held by such Member immediately prior to such action multiplied by a
fraction, the numerator of which shall be the number of Common Units outstanding
after giving effect to such action, and the denominator of which shall be the
number of Common Units outstanding immediately prior to such action. Such
adjustment shall be made successively whenever any event listed above shall
occur.

          (b) Restrictions on the Issuance of Class B-4 Units. Without the prior
              -----------------------------------------------
consent of holders of a majority of the number of Class B-4 Units then
outstanding, the Company shall not issue any Class B-4 Units except (i) pursuant
to the terms of the Muzak Merger Agreement, (ii) pursuant to the terms of the
Boyd Contribution Agreement, (iii) pursuant to Section 5.6(a), or (iv) pursuant
to Article X of the Securities Purchase Agreement.

          (c) Qualified Public Offering. Immediately prior to the consummation
              -------------------------
of any Qualified Public Offering (as such term is defined in the Members
Agreement), the Members agree to convert Class A Units and Class B-4 Units, on a
per Common Unit basis, into common equity securities of the applicable successor
corporation and that each share of such common equity securities of the
applicable successor corporation shall have equal voting, dividend and
liquidation rights. For greater certainty, the Members agree that upon the
conversion of the Company into a corporation (whether accomplished by merger,
conversion or other means) in order to consummate a Qualified Public Offering,
each Class A Unit and each Class B-4 Unit shall be treated equally in such
conversion for all purposes and no Class A Units or Class B-4 Units shall
entitle the holder thereof to any preferential rights including, without
limitation, to Distributions of Yield or Unpaid Yield.

                                   ARTICLE VI
                   Capital Contributions and Capital Accounts

6.1 Capital Contributions.

          (a) Prior to, or as of, the date hereof, each Person who is a Member
as of the date hereof has made or is deemed to have made, the Capital
Contributions giving rise to such Member's initial Capital Account and is deemed
to own the number, type and class or series of Units, in each case, in the
amounts set forth opposite such Member's name on the Members Schedule as in
effect on the date hereof.

          (b) No Member shall make or be required to make any additional
contributions to the Company with respect to such Member's Units. Except as
expressly

                                      -23-

<PAGE>

provided herein, no Member, in its capacity as a Member, shall have the right to
receive any cash or any other property of the Company.

6.2 Capital Accounts. The Company will maintain a separate Capital Account for
    ----------------
each Member according to the rules of Treasury Regulation section
1.704-1(b)(2)(iv). For this purpose, the Company may, upon the occurrence of the
events specified in Treasury Regulation section 1.704-1(b)(2)(iv)(f), increase
or decrease the Capital Accounts in accordance with the rules of such regulation
and Treasury Regulation section 1.704-1(b)(2)(iv)(g) to reflect a revaluation of
Company property.

6.3 Method of Determining Profits and Losses. For purposes of computing the
    ----------------------------------------
amount of any item of Company income, gain, loss or deduction to be allocated
pursuant to Article VIII and to be reflected in the Capital Accounts, the
determination, recognition and classification of any such item will be the same
as its determination, recognition and classification for federal income tax
purposes (including any method of depreciation, cost recovery or amortization
used for this purpose); provided, that:

          (a) the computation of all items of income, gain, loss and deduction
will include tax-exempt income and those items described in Treasury Regulation
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;

          (b) 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 will be taken into account as gain or loss from the disposition of
such property;

          (c) 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 will be computed by reference to the Book Value
of such property;

          (d) 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 will be computed by reference to the
property's Book Value in accordance with Treasury Regulation section
1.704-1(b)(2)(iv)(g); and

          (e) to the extent an adjustment to the adjusted tax basis of any
Company asset 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 will be treated as an item of gain (if the adjustment increases
the basis of the asset) or loss (if the adjustment decreases such basis).

6.4 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.

                                      -24-

<PAGE>

6.5 No Withdrawal. No Member will 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 in this Agreement or any applicable
Related Agreement.

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

6.7 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 by applicable law, no Member shall be
required to lend any funds to the Company or to make any additional Capital
Contributions to the Company.

          (c) No Member shall have any personal liability for the repayment of
any Capital Contribution of any other Member.

                                   ARTICLE VII
                                  Distributions

7.1 Order of Priority Generally. As and when determined by the Board, the
    ---------------------------
Company may make Distributions at any time or from time to time. Except as
otherwise expressly provided in this Agreement (including Sections 7.2, 7.3, 7.6
and 7.7), Article XI of the Securities Purchase Agreement, or any Certificate of
Designation, all Distributions shall be made in the following order and priority

<PAGE>

Distributions have been paid in respect of all such Common Units in an amount
equal to the amount of Distributions theretofore paid on the Common Units which
have theretofore been paid the third least amount, and so on until the same
amount has been paid in respect of all Common Units and thereafter Distributions
shall be made pro rata among the holders of Common Units upon which less than

              -----
number of Common Units owned by each such holder.

7.2 No Right to Receive Certain Distributions. Notwithstanding Section 7.1:
    -----------------------------------------

          (a) On Class B Units. A holder of any Class B Unit will forego
              ----------------
Distributions which would otherwise be made in respect of such Class B Unit from
time to time pursuant to Section 7.1 (including by reason of Section 7.2(b)) in
such amount(s) as may be required so that the aggregate amount of Distributions
foregone with respect to such Class B Unit by reason of this Section 7.2(a) is
equal to the Non-Distribution Amount for such Class B Unit; provided, that the
                                                            --------
amount of any Distribution foregone by a holder of any Class B Unit shall be
treated as having been received by such holder for purposes of calculating the
Catch-Up Amount and of determining whether, and to what extent, such holder is
entitled to receive Distributions under Section 7.1(i). No holder of any Class B
Unit will later have the right to receive any Distribution which is foregone
pursuant to this Section 7.2(a), except to the extent that any portion of such
foregone Distribution may ultimately be reallocated to such holder in accordance
with Section 7.2(b).

          (b) Reallocation. All Distributions that are foregone in respect of
              ------------
any Class B Unit pursuant to Section 7.2(a) will be reallocated and paid instead
to the holders of Common Units in accordance with Sections 7.1(i) and 7.1(j)
(subject again to being foregone pursuant to Section 7.2(a)).

7.3 Tax Distributions. Notwithstanding the priority of Distributions in Section
    -----------------
7.1 or the effect of the Non-Distribution Amount in Section 7.2, the Company
will, consistent with and subject to any restrictions which may be imposed under
any contractual obligation of the Company or its Subsidiaries or applicable law,
make Distributions to each Member in amounts such that, on the fifth Business
Day prior to each date on which annual or quarterly federal income tax payments
are required to be made by individuals, such Member has received Distributions
(whether pursuant to this Section 7.3 or otherwise) in aggregate amounts equal
to the excess, if any, of (a) the product of (i) the estimated Net Taxable
Profits allocable to such Member as of the end of the fiscal quarter in respect
of which such estimated federal income taxes are to be paid, multiplied by (ii)
the highest effective income tax rate (federal, state and local, adjusted for
any deductions and credits allowed by one taxing authority for income taxes paid
to another taxing authority) that is applicable to any Member (segregating, with
respect to the application of this Section 7.3, Net Taxable Profits for which
different income tax rates under this Section 7.3 apply), over (b) all previous
Distributions made to such Member in respect of

                                      -27-

<PAGE>

such allocable Net Taxable Profits. The Company will, consistent with and
subject to any restrictions which may be imposed under any contractual
obligation of the Company or its Subsidiaries or applicable law, cause such
Distributions to be made in a manner which permits such Members to use the
proceeds of such Distributions to make on a timely basis all required estimated
payments of income taxes in respect of the taxable income so allocated to them.
The Distributions required by this Section 7.3 will, consistent with and subject
to any restrictions which may be imposed under any contractual obligation of the
Company or its Subsidiaries or applicable law, be made (i) without regard for
the relative priorities and amounts set forth in Section 7.1 and (ii) without
regard to Section 7.2. Distributions made to a Member pursuant to this Section
7.3, however, shall be taken into account for purposes of this Agreement as if
they were made under Section 7.1 in respect of the allocations of Net Profit (or
separately allocated items of income and gains) to which they relate and,
therefore, shall reduce the Distributions that otherwise would be made to such
Member under Section 7.1 in respect of such income. No Member shall be liable to
the Company for any amount Distributed to it pursuant to this Section 7.3 or for
any interest on such amount.

7.4 Indemnification and Reimbursement for Payments on Behalf of a Member. If the
    --------------------------------------------------------------------
Company is required to withhold and remit any federal, state, foreign or local
income taxes levied on all or part of a Member's allocable share of net income
and gains, such withholding by the Company shall be treated as a Distribution to
the Member for whom such withholding is made and shall proportionately reduce
the amount of Distributions to be paid directly to such Member. If the Board
determines that the Company lacks sufficient funds to make Distributions in an
aggregate amount that would allow for any such withholding, the Member for whom
such withholding is to be made shall make Capital Contributions of cash or
immediately available funds in the amount needed by the Company after said
Distributions have been made to satisfy such withholding liability within ten
days after being so notified by the Company. Should a Member fail to timely make
any such Capital Contributions, such Member shall be in default and shall
indemnify and hold the Company and the other Members harmless for any costs,
penalties, payments or damages incurred by the Company or the other Members as a
result of such failure, and such Member shall pay the Company interest in
respect to any disbursements by the Company as a result of such Member failing
to timely make the Capital Contributions required by this Section 7.4 at the
lower of the Prime Rate plus three percentage points per annum, compounded
monthly, or the highest rate of interest allowed by applicable law. The Company

<PAGE>

the amounts and of such character as determined according to, and subject to the
exceptions contained in Treasury Regulation section 1.704-2(f). This Section
8.2(b) is intended to be a minimum gain chargeback provision that complies with
the requirements of Treasury Regulation section 1.704-2(f) and shall be
interpreted in a manner consistent with such intention.

          (c) Qualified Income Offset. If any Member who unexpectedly receives
              -----------------------
an adjustment, allocation, or Distribution described in Treasury Regulation
section 1.704-1(b)(2)(ii)(d)(4), (5), and (6) has a negative balance in such
Member's Adjusted Capital Account as of the end of any Fiscal Year, computed
after the application of Sections 8.2(a) and 8.2(b) but before the application
of any other provision of Section 8.1 or Section 8.2, then Profits for such
Fiscal Year shall be allocated to such Member in proportion to, and to the
extent of, such a negative balance in such Member's Adjusted Capital Account.
This Section 8.2(c) is intended to be a qualified income offset provision as
described in Treasury Regulation section 1.704-1(b)(2)(ii)(d) and shall be
interpreted in a manner consistent with such intention.

          (d) Adjustment of Tax Basis. Profits and Losses described in Section
              -----------------------
6.3(e) shall be allocated in a manner consistent with the manner that the
adjustments to the Capital Accounts are required to be made pursuant to Treasury
Regulation section 1.704-1(b)(2)(iv)(j), (k) and (m).

          (e) Transaction with Member. If, and to the extent that, any Member is
              -----------------------
deemed to recognize any item of income, gain; loss, deduction or credit as a
result of any transaction between such Member and the Company pursuant to any of
Code sections 1272-1274, 7872, 483 and 482 or any similar provision now or
hereafter in effect, and the Tax Matters Partner determines that any
corresponding Profits or Losses of the Company should be allocated to the Member
who recognized such item in order to reflect the Member's economic interests in
the Company, then the Company may so allocate such Profits or Losses.

8.3 Tax Allocations.
    ---------------

          (a) Generally. The income, gains, losses, deductions and credits of
              ---------
the Company will 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 is not permitted by the Code or
          -----------
other applicable law, the Company's subsequent income, gains, losses. deductions
and credit will be allocated among the Members so as to reflect as nearly as
possible the allocation set forth in this Agreement in computing their Capital
Accounts.

          (b) Differences Between Book Value and Tax Basis. Items of Company
              --------------------------------------------
taxable income, gain, loss and deduction with respect to any property
contributed to the capital of the Company will be allocated among the Members in
accordance with Code section 704(c) 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.

          (c) Adjustments in Book Value. If the Book Value of any Company asset
              -------------------------
is adjusted pursuant to Section 6.3, then subsequent allocations of items of
taxable income, gain, loss and deduction with respect to such asset will take
into account any variation between the

                                      -34-

<PAGE>

adjusted basis of such asset for federal income tax purposes and its Book Value
in the same manner as under Code section 704(c).

          (d) Allocations of Credits and the Like. Allocations of tax credits,
              -----------------------------------
tax credit recapture, and any items related thereto will be allocated to the
Members according to their interests in such items as determined by the Tax
Matters Partner taking into account the principles of Treasury Regulation
section 1.704-1(b)(4)(ii).

          (e) No Effect on Capital Accounts. Allocations pursuant to this
              -----------------------------
Section 8.3 are solely for purposes of federal, state and local taxes and will
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 provision of this Agreement.

8.4 Curative Allocations. If the Tax Matters Partner determines, after
    --------------------
consultation with counsel experienced in income tax matters, that the allocation
of any item of Company income, gain, loss, deduction or credit (an "unallocated
                                                                    -----------
item") is not specified in this Agreement or that the allocation of any item of
----
Company income, gain, loss, deduction or credit (a "misallocated item") under
                                                    -----------------
this Agreement is in the Board's reasonable judgment inconsistent with the
Members' economic interests in the Company (determined by reference to the
amounts Distributable to the Members hereunder and otherwise applying the
general principles of Treasury Regulation section 1.704-l(b) and the factors set
forth in Treasury Regulation section 1.704-1(b)(3)(ii)), then the Company shall
allocate such unallocated items, or reallocate such misallocated items, to
reflect such economic interests; provided, that no such allocation will have any
                                 --------
material effect on the amounts Distributable to any Member, including the
amounts to be Distributed upon the complete liquidation of the Company.

    ---------
to the Company's business, including all books and records necessary to provide
any information, lists and copies of documents required to be provided pursuant

    ----------
for federal, state and local income tax purposes, and the Company and each
Member shall file all tax returns on the basis consistent therewith.

    -------

Fiscal Year, all information necessary for the preparation of such Person's
United States federal income tax returns and any state, local and foreign income
tax returns which such Person is required to file as a result of the Company
being engaged in a trade or business within such state, local or foreign
jurisdiction, including a

                                      -35-

<PAGE>

statement showing such Person's share of income, gains, losses, deductions and
credits for such year for United States federal income tax purposes (and, if
applicable, state, local or foreign income tax purposes) and the amount of any
Distributions made to or for the account of such Person. Upon the written
request of any such Person made not later than 30 days after the end of each
Fiscal Year, the Company will use reasonable efforts to deliver or cause to be
delivered any additional information necessary for the preparation of any state,
local and foreign income tax returns which must be filed by such Person.

9.4 Tax Elections. The taxable year will be the Fiscal Year, unless the Tax
    -------------
Matters Partner determines otherwise in compliance with applicable laws. The Tax
Matters Partner will determine whether to make or revoke any available election
pursuant to the Code. Each Member will upon request supply the information
necessary to give proper effect to any such election.

and to expend Company funds for professional services and costs associated
therewith; provided, that the Tax Matters Partner may be replaced by action of a
           --------
Majority in Voting Interest. Each Member agrees to cooperate with the Tax
Matters Partner and to do or refrain from doing any or all things reasonably
requested by the Tax Matters Partner with respect to the conduct of such
proceedings. Subject to the foregoing proviso, the Tax Matters Partner will have
sole discretion to determine whether the Company (either on its own behalf or on
behalf of the Members) will contest or continue to contest any tax deficiencies
assessed or proposed to be assessed by any taxing authority. Any deficiency for
taxes imposed on any Member (including penalties, additions to tax or interest
imposed with respect to such taxes) will be paid by such Member, and if required
to be paid (and actually paid) by the Company, will be recoverable from such
Member as provided in Section 7.4.

Company pursuant to section 18-802 of the Delaware Act without the approval of a
Majority in Voting Interest.

<PAGE>

has been completed, the assets of the Company have been Distributed as provided

          (a) Liquidator. Upon dissolution of the Company, the Board will
              ----------
appoint a Person to act as the "Liquidator," and such Person shall act as the
                                ----------
Liquidator unless and until a successor Liquidator is appointed as provided in
this Section 10.2. The Liquidator will agree not to resign at any time without
30 days' prior written notice to the Board. The Liquidator may be removed at any
time, for or without cause, by notice of removal and appointment of a successor
Liquidator approved by the Board. Any successor Liquidator will succeed to all
rights, powers and duties of the former Liquidator. The right to appoint a
successor or substitute Liquidator in the manner provided in this Section 10.2
will be recurring and continuing for so long as the functions and services of
the Liquidator are authorized to continue under the provisions of this
Agreement, and every reference in this Agreement to the Liquidator will be
deemed to refer also to any such successor or substitute Liquidator appointed in
the manner provided in this Section 10.2. The Liquidator will receive as
compensation for its services (i) no additional compensation, if the Liquidator
is an employee of the Company or any of its Subsidiaries, or (ii) such
compensation as the Board may approve, if the Liquidator is not such an
employee, plus, in either case, reimbursement of the Liquidator's out-of-pocket
          ----
expenses in performing its duties.

          (b) Liquidating Actions. The Liquidator will 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) First, to the payment of the Company's debts and
                        -----
          obligations to its creditors (including Members), including sales
          commissions and other expenses incident to any sale of the assets of
          the Company, in order of the priority provided by law;

                    (ii) Second, to the establishment of and additions to such
                         ------
          reserves as the Board deems necessary or appropriate; and

                    (iii) Third, to the Members, in accordance with Section 7.1,
                          -----
          subject to Section 7.2, or any Certificate of Designation and the
          final paragraph of this Section 10.2(b).

The reserves established pursuant to clause (ii) above will be paid over by the
Liquidator to a bank or other financial institution, to be held in escrow for
the purpose of paying any such contingent or unforeseen liabilities or
obligations and, at the expiration of such period as the Board deems advisable,
such reserves will be Distributed to the Members in accordance with Section 7.1,
subject to Section 7.2 or any Certificate of Designation. The allocations and
Distributions provided for in this Agreement are intended to result in the
Capital Account of each Member immediately prior to the Distribution of the
Company's assets pursuant to this Section 10.2(b) being equal to the amount
Distributable to such Member pursuant to this Section 10.2(b). The Company is
authorized to make appropriate adjustments in the allocation of Profits and
Losses as necessary to cause the amount of each Member's Capital Account
immediately prior to the Distribution of the Company's assets pursuant to this
Section 10.2(b) to equal the amount

                                      -37-

<PAGE>

Distributable to such Member pursuant to this Section 10.2(b). In furtherance of
the foregoing, and notwithstanding anything in this Agreement or any Certificate
of Designation to the contrary, the Class A Units issued to BancAmerica, New
York Life and Northwestern (the "Series A Preferred Unitholders") on the date
hereof are intended to be the economic equivalents of "profits interests" within
the meaning of section 2.02 of Revenue Procedure 93-27, 1993-2 C.B. 343.
Allocations of Profits and Losses (including, for the avoidance of doubt, items
of gross income and gross deduction) shall be made in such manner as necessary
(either with respect to the Fiscal Year of liquidation, or, if the due date for
the Company's tax return for the preceding year (without regard to extensions)
has not passed (and there are not sufficient items of Profit or Loss in the
current year) with respect to such prior year) to yield the result described in
the second preceding sentence, and the holders of Class A Units issued pursuant
to the Securities Purchase Agreement on the date hereof shall not be entitled to
any distribution pursuant to Section 7.1(d) upon a liquidation of the Company
unless an amount of Profit has been allocated to such holders pursuant to this
sentence equal to the amount to be distributed to them; provided, that the
                                                        --------
Company shall not make any Distributions under Section 10.2(b)(iii) without the
express written consent of the holder(s) of a more than sixty percent of the
outstanding Class A Units issued pursuant to the Securities Purchase Agreement
on the date hereof unless such Distributions can be made pursuant to Section
7.1(d) on a pro rata per Common Investment Unit basis.

          (c) Distribution in Kind. Notwithstanding the provisions of Section
              --------------------
10.2(b) which require the liquidation of the assets of the Company, but subject
to the order of priorities set forth in Section 10.2(b), if upon dissolution of
the Company the Board determines that an immediate sale of part or all of the
Company's assets would be impractical or could cause undue loss to the Members,
the Board may, in its sole discretion, defer the liquidation of any assets
except those necessary to satisfy Company liabilities and reserves, and may, in
its absolute discretion, Distribute to the Members, in lieu of cash, as tenants
in common and in accordance with the provisions of Section 10.2(b), undivided
interests in such Company assets as the Liquidator deems not suitable for
liquidation. Any such Distribution in kind will be subject to such conditions
relating to the disposition and management of such properties as the Liquidator
deems reasonable and equitable and to any agreements governing the operating of
such properties at such time. For purposes of any such Distribution, the Board
will determine the Fair Market Value of any property to be Distributed in
accordance with any valuation procedure which the Board reasonably deems
appropriate.

          (d) Reasonable Time for Winding Up. A reasonable time will be allowed
              ------------------------------
for the orderly winding up of the business and affairs of the Company and the
liquidation of its assets pursuant to Section 10.2(b) in order to minimize any
losses otherwise attendant upon such winding up. Distributions upon liquidation
of the Company (or any Member's interest in the Company) and related adjustments
will be made by the end of the Fiscal Year of the liquidation (or, if later,
within 90 days after the date of such liquidation) or as otherwise permitted by
Treasury Regulation section 1.704-1(b)(2)(ii)(b).

          (e) Termination. 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

                                      -38-

<PAGE>

jurisdictions other than the State of Delaware and shall take such other actions
as may be necessary to terminate the Company.

10.3 Voluntary Dissolution. Notwithstanding anything to the contrary herein,
     ---------------------
without the prior consent of the Required B-4 Holders, neither the Board nor the
Members shall effect a voluntary dissolution of the Company (except in
connection with an Approved Company Sale (as such term is defined in the Members
Agreement)) unless the Members holding Class B-4 Units receive their pro rata
percentage (based on the ratio of the number of Class B-4 Units held by such
Members to the number of Common Units then outstanding) share of the assets of
the Company in such dissolution or pro rata percentage share of the equity
securities issued by any successor entity to the Company.

11.1 Restrictions. Each Member acknowledges and agrees that such Member shall
     ------------
not Transfer, or create or suffer to exist any Encumbrance against, any Units
except in accordance with the provisions of this Article XI and the Related
Agreements. Any attempted Transfer or Encumbrance in violation of the preceding
sentence shall be deemed null and void for all purposes, and the Company will
not record any such Transfer or Encumbrance on its books or treat any purported
transferee as the owner of such Units for any purpose.

11.2 General Restrictions on Transfer.
     --------------------------------

          (a) Notwithstanding anything to the contrary in this Agreement, no
transferee of any Units received pursuant to a Transfer (but excluding any
transferee that was a Member or who is an Affiliate of any Member to whom Series
A Preferred Units have been issued immediately prior to such a Transfer, who
shall automatically become a Member with respect to any Units such transferee so
acquires) shall become a Member in respect of or be deemed to have any ownership
rights in the Units so Transferred unless the purported transferee is admitted
as a Member as set forth in Section 11.3(a).

          (b) Following a Transfer of any Units that is permitted under this
Article XI, the transferee of such Units shall succeed to the Capital Account
associated with such Units and shall receive allocations and Distributions
hereunder in respect of such Units. Notwithstanding the foregoing, Profits,
Losses and other items will be allocated between the transferor and the
transferee according to Code Section 706.

          (c) Any Member who Transfers all of its Units (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.

11.3 Procedures for Transfer. Subject in all events to the general restrictions
     -----------------------
on Transfers contained in Sections 11.1, 11.2 and 11.5, a Member may Transfer
all or any part of its Units in accordance with this Section 11.3.

                                      -39-

<PAGE>

          (a) No Transfer of Units 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 Joinder. Upon execution of a Joinder, 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 and thereupon the Company shall reissue the applicable Units in
the name of such prospective transferee.

          (b) Unless waived by the Company, no Member may Transfer any
Restricted Securities (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. If such
opinion of counsel reasonably acceptable in form and substance to the Company
further states that no subsequent Transfer of such Restricted Securities will
require registration under the Securities Act, the Company will promptly upon
such Transfer deliver new certificates for such securities which do not bear the
Securities Act legend set forth in Section 11.4(b).

11.4 Legend.
     ------

          (a) The certificates representing the Units will bear the following
legend:

     "THE TRANSFER OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE IS SUBJECT
     TO THE CONDITIONS SPECIFIED IN A LIMITED LIABILITY COMPANY AGREEMENT AMONG
     THE ISSUER AND ITS MEMBERS, A COPY OF SUCH LIMITED LIABILITY COMPANY
     AGREEMENT AS IN EFFECT FROM TIME TO TIME WILL BE FURNISHED WITHOUT CHARGE
     BY THE ISSUER TO THE HOLDER HEREOF UPON WRITTEN REQUEST."

          (b) Each certificate or instrument evidencing Restricted Securities
and each certificate or instrument issued in exchange for or upon the Transfer
of any Restricted Securities (if such securities remain Restricted Securities
after such Transfer) shall be stamped or otherwise imprinted with a legend in
substantially the following form:

     "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
     UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), AND MAY NOT BE
     SOLD OR TRANSFERRED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT
     UNDER THE ACT OR AN EXEMPTION FROM REGISTRATION THEREUNDER."

Upon the request of any holder of Restricted Securities, the Company shall
remove the Securities Act legend set forth above from the certificates for such
Restricted Securities; provided, that such Restricted Securities are eligible
for sale pursuant to Rule 144(k) (or any similar rule or rules then in effect)
under the Securities Act.

                                      -40-

<PAGE>

          (c) In addition, each certificate or instrument evidencing Restricted
Securities and each certificate or instrument issued in exchange for or upon the
Transfer of any Restricted Securities (if such securities remain Restricted
Securities after such Transfer) shall be stamped or otherwise imprinted with any
additional legends as may be required by the Company, as applicable to the
holder of such certificate or instrument.

11.5 Limitations.
     -----------

          (a) Notwithstanding anything to the contrary in this Agreement, no
Unit may be Transferred or issued by the Company if such Transfer or issuance
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 Unit shall be permitted or recognized by
the Company (within the meaning of Treasury Regulation section 1.7704-1(d)) and
the Company shall not issue any Units if and to the extent that such Transfer or
issuance 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)).

          (c) Notwithstanding anything to the contrary in this Agreement, no
Unit may be Transferred and the Company may not issue any Unit unless (i) such
Transfer or issuance, as the case may be, shall not affect the Company's
existence or qualification as a limited liability company under the Delaware
Act, (ii) such Transfer or issuance, as the case may be, shall not cause the
Company to be classified as other than a partnership for United States federal
income tax purposes, (iii) such Transfer or issuance, as the case may be, shall
not result in a termination of the Company under Code section 708, unless the
Board determines that any such termination will not have a material adverse
impact on the Members and (iv) such Transfer or issuance, as the case may be,
shall not cause the application of the tax-exempt use property rules of Code
sections 168(g)(I)(B) and 168(h) to the Company or its Members.

11.6 Tax Matters. Upon the Transfer of any Unit, if the transferor owns a
     -----------
Membership Interest representing more than 5% (or 2% if such transferor is
transferring Units purchased pursuant to the Securities Purchase Agreement) of
the aggregate Capital Account balances of all Member determined immediately
prior to such Transfer, then, at the request of such transferor at the time of
such Transfer, the Board will cause the Company to elect, pursuant to section
754 of the Code, to adjust the tax basis of the Company's properties as provided
by sections 734 and 743 of the Code.

11.7 Conversions. Each of the Members agree that upon authorization by the Board
     -----------
of the conversion or reorganization of the Company into another entity form
(including a corporation) (a "Conversion"), it will take all necessary and
                              ----------
desirable actions to cause the Conversion as authorized by the Board to occur,
including by (a) consenting to, voting for and raising no objections against the
Conversion or the process pursuant to which the Conversion is arranged (whether
such Conversion is effected through a merger, sale of assets, Transfer of
Membership Interests or otherwise), (b) executing any documents (including a
shareholders' agreement or

                                      -41-

<PAGE>

similar document) necessary to prevent the Conversion from altering the relative
rights of the Members with respect to their ownership of equity in the Company,
and (c) waiving any potential claim, including any claim for breach of fiduciary
duty, which it may have against any officer, shareholder or member of the Board,
any other Member, the Company or any Affiliate of the foregoing to the extent
arising out of or relating to any Conversion. In connection with any Conversion,
the Company shall use its good faith efforts to assure that each Member fully
participates in such Conversion with substantially the same relative rights,
preferences and obligations after such Conversion as were applicable prior to
such Conversion and shall give written notice to the Members that the new entity
had been formed, enclosing with such notice copies of any charter documents and
by-laws of the new entity and describing the form of the transaction by which
the business of the Company is to be acquired by the new entity. Upon approval
of any Conversion in accordance with the provisions of this Agreement, the Board
by the terms hereof shall have a power of attorney to execute all documents,
