          Accounts, the amount of such adjustment to the Capital Accounts shall

     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-

                                       -10-

<PAGE>

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.

          (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.

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.

          (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.

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,

               -------------------------------------------------------
Majority in Interest of the Members may remove any officer, for any reason or

          --------------------------------------------
her duties, each of the officers shall be entitled to rely in good faith on the
provisions of this Agreement and on 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

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

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

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

                                       -14-

<PAGE>

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.

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

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

     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.

          (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

          (b)  In order to permit the Company to qualify for the benefit of a

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

compensation for its services as may be approved by a Majority in Interest of
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

           (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

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.
