     by such Member to the capital of the Company, the amount of liabilities of
     the Company assumed by the Member or to which property distributed to the
     Member was subject and such Member's share of the Profit of the Company and
     of any items in the nature of income or gain separately allocated to the
     Members; and there shall be charged against each Member's Capital Account
     the amount of all cash distributions to such Member, the fair market value

     assets in-kind to any Member, the Capital Account of each Member shall be

     1(b)(2)(iv)(f), the Capital Account balance of each Member shall be
     adjusted to the extent provided under such Treasury Regulation to reflect
     the Member's allocable share (as determined under Article Three) of the
     items of Profit or Loss that would be realized by the Company if it sold
     all of its property at its fair market value (taking Code Section 7701(g)
     into account) on the day of the adjustment.

                  ---------------------------------------------------
shall be entitled to withdraw any part of its or his Capital Contribution, to

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

     priority as of the close of such Fiscal Year or other accounting period:

                         3.1.1.1   First, to the Members in proportion to their
          respective Percentage Interests until the aggregate cumulative amount
          of Profits allocated to each Member pursuant to this Section 3.1.1.1
          equals the aggregate cumulative amount of Net Losses allocated to the
          Members pursuant to Section 3.1.2.2; and

                                      -4-
<PAGE>

                         3.1.1.2   Thereafter, eighty (80%) percent to the
          Members in proportion to their respective Percentage Interests, and
          twenty (20%) percent to the Managing Member.

                  3.1.2  Subject to Sections 3.3 through 3.5, Net Losses of the
     Company shall be allocated as follows and in the following order of
     priority as of the close of such Fiscal Year or other accounting period:

                         3.1.2.1   First, eighty percent (80%) to the Members in
          proportion to their respective Percentage Interests and twenty percent
          (20%) to the Managing Member until the aggregate cumulative amount of
          Losses allocated to each Member pursuant to this Section 3.1.2.1
          equals the aggregate cumulative amount of Profits allocated to such
          Member pursuant to Section 3.1.1.2; and

                         3.1.2.2   Second, to the Members in proportion to their
          respective Percentage Interests.

     Section 3.2  Special Allocation Rules.  Before any allocations are made
                  ------------------------
pursuant to Section 3.1, the following special allocations shall be made in the
following order:

                  3.2.1  If any Member unexpectedly receives any adjustment,
     allocation or distribution described in Sections 1.704-1(b)(2)(ii)(d)(4),
     1.704-1(b)(2)(ii)(d)(5) or 1.704-1(b)(2)(ii)(d)(6) of the Regulations which
     causes it to have an, or increases the amount of its, Adjusted Capital
     Account Deficit, items of Company income and gain (computed with the
     adjustments set forth in clauses (i), (ii) and (iii) of the definition of
     "Profits" and "Losses") shall be specially allocated to such Member in an
     amount and manner sufficient to eliminate, to the extent required by the
     Regulations, such Member's Adjusted Capital Account Deficit as quickly as
     possible, provided that an allocation pursuant to this Section 3.2.1 shall
     be made to a Member only if and to the extent that such Member would have
     an Adjusted Capital Account Deficit after all other allocations provided
     for in this Article Three have been tentatively made as if this Section
     3.2.1 were not in this Agreement. This Section 3.2.1 is intended to
     constitute a "qualified income offset" as defined in Section 1.704-
     1(b)(2)(ii)(d) of the Regulations.

                  3.2.2  If any Member has an Adjusted Capital Account Deficit
     as of the end of any Fiscal Year or other accounting period of the Company
     that is in excess of the amount such Member is deemed to be obligated to
     restore to his Capital Account pursuant to the penultimate sentences of
     Sections 1.704-2(g)(1) and 1.704-2(h)(5) of the Regulations (the so-called
     deficit restoration rule), items of Company income and gain (computed with
     the adjustments set forth in clauses (i), (ii) and (iii) of the definition
     of "Profits" and "Losses") in the amount of such excess shall be specially
     allocated to such Member as quickly as possible, provided that an
     allocation pursuant to this Section 3.2.2 shall be made to a Member only if
     and to the extent that such Member would have an Adjusted Capital

                                      -5-
<PAGE>

     Account Deficit that is in excess of the amount such Member is deemed to be
     obligated to restore to his Capital Account pursuant to the penultimate
     sentences of Sections 1.704-2(g)(1) and 1.704-2(h)(5) of the Regulations
     after all other allocations provided for in this Article Three have been
     tentatively made as if this Section 3.2.2 were not in this Agreement.

                  3.2.3  To the extent an adjustment to the adjusted tax basis
     of any asset of the Company pursuant to Section 734(b) or Section 743(b) of
     the Code is required, pursuant to Section 1.704-1(b)(2)(iv)(m) of the
     Regulations, 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 the basis of the asset), and such gain or loss
     shall be specially allocated to the Members in a manner that is consistent
     with the manner in which their Capital Accounts are required to be adjusted
     pursuant to Section 1.704-1(b)(2)(iv)(m) of the Regulations.

                  3.2.4  Notwithstanding Section 3.1, an allocation of Loss
     shall not be made to a Member to the extent that such allocation would
     cause such Member to have an Adjusted Capital Account Deficit. An
     allocation of Loss that would be made to a Member but for this Section
     3.2.4 shall instead be made to the other Members to the extent of and in
     proportion to the amounts of such loss that they could then be allocated
     without themselves having Adjusted Capital Account Deficits (or, if such
     other Members would not have Adjusted Capital Account Deficits, in
     proportion to their respective Capital Contributions) and thereafter to the
     Capital Member.

     Section 3.3  Corrective Allocations.  The allocations set forth in Section
                  ----------------------
3.2 (the "Regulatory Allocations") are intended to comply with certain
          ----------------------
requirements of Sections 1.704-1(b) and 1.704-2 of the Regulations.
Notwithstanding any other provision of this Article Three, the Regulatory
Allocations shall be taken into account in making allocations of items of
income, gain, loss, deduction and expenditure among the Members so that, to the
extent possible consistent with the Code and the Regulations and on a cumulative
basis, the respective net amounts of such allocations of other items and the
Regulatory Allocations to the Members are equal to the respective net amounts
that would have been allocated to the Members had no Regulatory Allocations been
made. The Managing Member shall apply this Section 3.3 at such times and in
whatever order, and shall divide allocations made pursuant to this Section 3.3
among the Members in such manner, as it determines is likely to minimize any
economic distortions that might otherwise be caused by the Regulatory
Allocations.

     Section 3.4  Tax Allocations.
                  ---------------

                                      -6-
<PAGE>

                  3.4.1  Tax allocations for each _Fiscal Year or other
     accounting period of the Company shall be made consistent with the
     allocations of Profit and Loss and items specially allocated pursuant to
     Sections 3.2 and 3.3 for such year or period, except that, solely for tax
     purposes, (i) items of income, gain, loss and deduction with respect to
     Company assets reflected hereunder in the Members' Capital Accounts and on
     the books of the Company at values that differ from the Company's adjusted
     tax bases in such assets shall be allocated among the Members so as to take
     account of those differences pursuant to Section 1.704-3 of the Regulations

     not less frequently than annually) in proportion to their respective
     Capital Account balances.

                  3.5.2  The Managing Member shall endeavor (if practical and
     reasonable to do so in light of the circumstances of the Company) to
     distribute, if available, sufficient amounts of Available Cash to the
     Members in accordance with this Section 3.5 to enable all Members to make

                  3.6.1  Upon the liquidation of the Company, the assets of the
     Company shall first be applied to the payment of, or the establishment of
     adequate reserves or other provision for the payment of, the debts and
     obligations of the Company. Thereafter, there shall be made a final
     allocation of Profit or Loss, as the case may be, and other items to the
     Members' Capital Accounts in accordance with Sections 3.1 through 3.3. The
     assets of the Company (or the proceeds of sales or other dispositions in
     liquidation of assets of the Company) remaining after the payment or other
     provision for the Company's debts and obligations shall then be distributed
     to the Members in proportion to the positive balances in their Capital
     Accounts determined after the final allocation of Profit or Loss and other
     items to Capital Accounts has been made. Amounts reserved or otherwise set
     aside in connection with the Company's liquidation for the payment of
     Company debts and obligations shall be

                                      -7-
<PAGE>

     distributed to the Members, in the same proportions that such amounts would
     have been distributed hereunder if distributed upon the Company's
     liquidation, as soon as practicable. No Member shall be required or
     otherwise obligated to restore or contribute any deficit balance in such
     Member's Capital Account upon the liquidation of the Company.

                  3.6.2  The Managing Member, or an authorized liquidating
     trustee if one is appointed, may distribute assets of the Company in kind
     upon the liquidation of the Company. Any asset to be distributed in kind
     shall be distributed on the basis of its Fair Market Value as determined in
     accordance with the provisions of Section 3.8. For purposes of making the
     final allocation of Profit or Loss, and other items required by Section
     3.6.1, any asset other than cash that is to be distributed to one or more
     Members in kind shall be treated as having then been sold by the Company
     for its Fair Market Value as determined in accordance with the provisions
     of Section 3.8. Any Member entitled to any interest in such assets shall,
     unless otherwise determined by the Members, receive separate assets of the
     Company and not an interest as a tenant-in-common with other Members so
     entitled in any asset being distributed.

                  3.7.1  The Managing Member shall distribute to the Members
     Portfolio Securities which are Marketable Securities, unless the Capital
     Member determines that a distribution of such securities would not be in
     the best interests of the Company. Such Portfolio Securities shall be
     distributed in accordance with Section 3.5 or 3.6, as applicable, based on
     their respective Fair Market Values. The Managing Member shall promptly
     notify the Members each time a Portfolio Security becomes a Marketable
     Security. The Managing Member shall not distribute Portfolio Securities
     that are not Marketable Securities at any time other than upon the
     liquidation of the Company.

                  3.7.2  The Managing Member may cause certificates evidencing
     any securities to be distributed to be imprinted with legends as to such
     restrictions on transfers that it may deem necessary, including legends as
     to applicable Federal or state securities laws or other legal or
     contractual restrictions, and may require any Member to which securities
     are to be distributed to agree in writing that such securities will not be
     transferred except in compliance with such restrictions and applicable law.

     Section 3.8  Valuation. For all purposes of this Agreement, the Fair Market
                  ---------
Value of securities and other property of the Company shall be determined as
follows:

                  3.8.1  Marketable Securities shall (i) if traded on a national
     securities exchange, be valued at the average of their last sales price on
     the exchange on which such Marketable Securities are traded on the last ten
     trading days immediately preceding the date of determination, or (ii) if
     the trading of such Marketable Securities is reported through the National
     Association of Securities Dealers Automated Quotation System, such
     Marketable

                                      -8-
<PAGE>

     Securities shall be valued at the average of the last sale prices as shown
     by the National Association of Securities Dealers Automated Quotation
     System on the last ten trading days on which such Marketable Securities
     were traded immediately preceding the date of determination.

                  3.8.2  All property other than Marketable Securities shall be
     valued by the Managing Member in good faith. Factors considered in valuing
     individual securities shall include, but need not be limited to, purchase
     price, estimates of liquidation value, the price at which Members receiving
     a distribution of securities will be able to sell them and the time at
     which such securities may be sold, the existence of restrictions on
     transferability, prices received in recent significant private placements
     of securities of the same issuer, prices of securities of comparable public
     companies engaged in similar businesses and changes in the financial
     condition and prospects of the issuer.

                  3.8.3  Upon any valuation of securities or other property of
     the Company pursuant to this Section 3.8 (other than Marketable Securities,
     to which this Section 3.8.3 shall not apply), the Managing Member shall
     notify the Capital Member in writing of the Fair Market Value of such
     securities or other property as determined by the Managing Member in
     accordance with the provisions of Section 3.8. The Capital Member shall,
     not more than ten Business Days after the receipt of such notice from the
     Managing Member, furnish notice in writing to the Managing Member stating
     whether or not it has approved or has not approved the Managing Member's
     valuation. If the Capital Member approves such valuation (or shall have
     failed to provide the Managing Member with the aforementioned notice within
     such ten Business Days), such valuation shall constitute the Fair Market
     Value of such property for all purposes hereof. If the Capital Member does
     not approve such valuation, and if the Managing Member and the Capital
     Member cannot agree on a valuation within five Business Days (or such other
     period of time as the Managing Member and the Capital Member may determine)
     of the date on which the Capital Member advises the Managing Member that it
     has not approved such valuation, the Managing Member and the Capital Member
     shall jointly select an independent appraiser who shall be retained to
     determine, as promptly as practicable, the Fair Market Value of the
     property to be distributed. The Company shall pay the expenses of such
     appraiser.

     does not comply with the provisions of this Section 6.1 shall not be
     admitted to the Company as a Substitute Member and shall have none of the
     rights of the Capital Member and the assigning or transferring Capital
     Member in such case shall remain fully liable for all obligations hereunder
     as if such assignment or transfer had not occurred. The assignee or
     transferee of the Capital Member's Interest in the Company (an "Assignee")
     shall have the right to become a Substitute Member only if the following
     conditions are satisfied:

                         6.1.1.1   A duly executed and acknowledged written
          instrument of assignment shall have been delivered to the Company.

                         6.1.1.2   The Capital Member and the Assignee shall
          have executed and acknowledged such other instruments and taken such
          other action as the Managing Member shall reasonably deem necessary or
          desirable to effect such substitution, including, without limitation,
          the execution by the Assignee of a transfer document and an
          appropriate amendment to this Agreement.

                         6.1.1.3   The restrictions on transfer contained in
          Section 6.2 shall be inapplicable, and, if requested by the Managing
          Member, the Capital Member or the Assignee shall have obtained an
          opinion of counsel reasonably satisfactory to the Managing Member as
          to the legal matters set forth in that Section.

                         6.1.1.4   The Capital Member or the Assignee shall have
          paid all expenses incurred by or on behalf of the Company in

                         6.1.1.5   The Managing Member shall have Consented, in
          its sole and absolute discretion, to such substitution.

                         Any assignment or transfer not in compliance with this
          Article Six shall have no force or effect, and the assigning or
          transferring Member shall continue for all purposes under the Act and
          this Agreement to be a Member of the Company.

     Member.

     Section 6.2  Restrictions on Transfer. Notwithstanding any other provision
                  ------------------------
of this Agreement, no Member may assign or otherwise transfer all or any part of
its interest in the Company, and no attempted or purported assignment or
transfer of such interest shall be effective, if, in the opinion of counsel to
the Company, such assignment or transfer (i) may not be effected without
registration under the Securities Act of 1933, as amended, (ii) would result in
the violation of any applicable state securities laws, (iii) would result in a
termination of the Company under Section 708 of the Code, unless such a transfer
is consented to by all of the Members or (iv) would result in the treatment of
the Company as an association taxable as a corporation or as a "publicly-traded
limited partnership" for tax purposes, unless such a transfer is consented to by
all of the Members. The Company shall not be required to recognize any
assignment until the instrument conveying such interest has been delivered to
the Company for recordation on the books of the Company. Unless an assignee
becomes a substituted Member in accordance with the provisions of Section 6.1,
it shall not be entitled to any of the rights granted to a Member hereunder,
other than the right to receive all or part of the share of the Profits, Losses,
distributions of cash or property or returns of capital to which his assignor
would otherwise be entitled.

     or any Member for any act or omission taken by the Managing Member in good
     faith and in the belief that such act or omission is in the best interests
     of the Company; provided that such act or omission is not in violation of
     this Agreement and does not constitute negligence, misconduct, fraud or a
     willful violation of law by the Managing Member. The Managing Member shall
     not be liable to the Company or any other Member for any action taken by
     any other Member, nor shall any Managing Member (in the absence of
     negligence, misconduct, fraud or a willful violation of law by the Managing
     Member) be liable to the Company or any other Member for any action of any
     employee or agent of the Company provided that the Managing Member shall
     have exercised appropriate care in the selection and supervision of such

     Section 7.2  Indemnification of the Managing Member and the Capital Member.
                  -------------------------------------------------------------
Each Member and its respective partners, agents, employees and Affiliates (the
"Indemnitees") shall be and hereby are (i) indemnified and held harmless by the
Company and (ii) released by the other Members from and against any and all
claims, demands, liabilities, costs, expenses, damages, losses, suits,
proceedings and actions for which such Indemnitee has not otherwise been
reimbursed (collectively, "Liabilities"), whether judicial, administrative,
investigative or otherwise, of any nature whatsoever, known or unknown,
liquidated or unliquidated, that may accrue to the Company or any other Member
or in which any of the Indemnitees may become involved, as a party or otherwise,
arising out of the conduct of the business or affairs of the Company by the
respective Indemnitee or otherwise relating to this Agreement, provided that an
Indemnitee shall not be entitled to indemnification or release hereunder if it
shall have been determined by (i) in the case of the Capital Member or an
Indemnitee claiming by or through the Capital Member, a court of competent
jurisdiction, or (ii) in the case of the Managing Member or an Indemnitee
claiming by or through the Managing Member, by the Capital Member, that (x) such
person did not act in good faith and in a manner such person reasonably believed
to be in the best interests of the Company and, in the case of a criminal
proceeding, did not have reasonable cause to believe that its conduct was
lawful, or (y) such Liabilities shall have arisen from a violation of this
Agreement or the negligence, misconduct, fraud or willful violation of law by
such Indemnitee, or actions of such Indemnitee outside the scope of and
unauthorized by this Agreement, and provided further that an Indemnitee shall
not be entitled to indemnification or release hereunder with respect to any
liability arising in connection with its activities performed for or on behalf
of any Portfolio Company, the securities of which have been sold or have been
distributed to the Members pursuant to Section 3.9, if such activities were
performed after the date on which such securities were sold or distributed. The
termination of any proceeding by settlement shall not, of itself, create a
presumption that the Indemnitee did not act in good faith and in a manner that
such person reasonably believed to be in the best interests of the Company or
that the Indemnitee did not have reasonable cause to believe that its conduct
was lawful. The indemnification rights provided for in this Section shall
survive the termination of the Company or this Agreement.

     Expenses incurred by an Indemnitee in defense or settlement of any claim
that may be subject to a right of indemnification hereunder may be advanced by
the Company prior to the final disposition thereof provided that the following
conditions are satisfied: (i) the claim relates to the performance of duties or
services by the Indemnitee on behalf of the Company and (ii) the Indemnitee
undertakes to repay the advanced funds to the Company if it is ultimately
determined that the Indemnitee is not entitled to be indemnified hereunder or
under applicable law. The right of any Indemnitee to the indemnification
provided herein shall be cumulative of, and in addition to, any and all rights
to which such Indemnitee may otherwise be entitled by contract or as a matter of
law or equity and shall extend to such Indemnitee's successors, assigns and
legal

                                      -16-

representatives. The obligations of the Members under this Article Seven shall
be satisfied only after any applicable insurance proceeds have been exhausted
and then only out of Company assets and, to the extent required by law,
distributions made by the Company to the Members, and the Members shall have no
liability to fund indemnification payment hereunder.
