<PAGE>

         SECTION 4.04. Allocation of Income and Loss With Respect to Membership
Interests Transferred.

                  If any Membership Interest is transferred during any Fiscal
Year, the Net Income or Net Loss attributable to such Membership Interest for

         SECTION 4.05.  Distributions of Cash Flow.

                  (a) Cash Flow of the Company shall be determined for each

                  Distributions of Cash Flow made within the first seventy-five

Transaction are to be paid to the Company in more than one installment, each
such installment (including any interest thereon) shall be allocated among the

         SECTION 4.07.  Special Allocation Rules.

         The following allocation rules shall apply notwithstanding any other
provisions of Sections 4.02 and 4.03, and the other provisions of Sections 4.02
and 4.03 shall be applied only after giving effect to the following rules. In
the event there is a conflict between any of the following rules, the earlier
listed rule shall govern.

                  (a) If in any Fiscal Year there is a net increase during such
year in the amount of Minimum Gain attributable to Member Nonrecourse Debts, the
Member(s) that bear the economic risk of loss with respect thereto (within the
meaning of Regulations section 1.704-1T(b)(4)(iv)(k)(1)) shall be specially
allocated items of Company loss or deduction in an amount equal to the excess of
(i) the amount of such net increase, over (ii) the aggregate amount of any
distributions during such Fiscal Year to such Member(s) of the proceeds of such
debt that are allocable to such increase in Minimum Gain. Items to be so
allocated shall be determined in accordance with Regulations section
1.704-1T(b)(4)(iv)(h).

                  (b) If in any Fiscal Year there is a net decrease in the
Company's Minimum Gain attributable to Nonrecourse Liabilities during such
Fiscal Year, each Member shall be specially allocated items of Company income
and gain for such Fiscal Year (and, if necessary, for subsequent Fiscal Years)
in proportion to, and to the extent of, an amount equal to the greater of the
following:

                           (i) the portion of such Member's share of the net
decrease in such Minimum Gain during such Fiscal Year (as such share is
determined pursuant to Regulations section 1.704-1T(b)(4)(iv)(f)) that is
allocable to the disposition of Company property subject to one or more
Nonrecourse Liabilities (as such allocable portion is determined pursuant to
Regulations section 1.704-1T(b)(4)(iv)(e)(2)); or

                           (ii) such Member's Excess Negative Balance at the end
of such Fiscal Year (determined before any allocation for such Fiscal Year of
any items of income, gain, loss, or deduction described in section 705(a)(2)(B)
of the Code).
<PAGE>

                  Items to be so allocated shall be determined and the
allocation made in accordance with Regulations section 1.704-1T(b)(4)(iv)(e).

                  (c) If in any Fiscal Year there is a net decrease in the
Company's Minimum Gain attributable to Member Nonrecourse Debts during such
Fiscal Year, the Member(s) that bear the economic risk of loss with respect to
such Member Nonrecourse Debts (within the meaning of Regulations section
1.704-1T(b)(4)(iv)(k)(1)) shall be specially allocated items of Company income
and gain for such Fiscal Year (and, if necessary, for subsequent Fiscal Years)
in an amount equal to the greater of the following:

                           (i) the net decrease in such Minimum Gain during such
Fiscal Year that is allocable to the disposition of Company property subject to
one or more Member Nonrecourse Debts (as such allocable portion is determined
pursuant to Regulations section 1.704-1T(b)(4)(iv)(h)(6)); or

                           (ii) such Member's (Members') Excess Negative Balance
at the end of such Fiscal Year (determined before any allocation for such Fiscal
Year of any items of income, gain, loss, or deduction described in section
705.1.(2)(B) of the Code).

                  Items to be so allocated shall be determined and the
allocation made in accordance with Regulations section 1.704-1T(b)(4)(iv)(h)(6).

                  (d) For purposes of allocating Company Nonrecourse Liabilities
among the Members pursuant to Regulations section 1.752-1T(a)(2)(i), the
respective interests of the Members in Company profits shall be equal to their
respective Percentage Interests.

                  (e) A Member shall not be allocated any amount of deduction or
loss (including Net Loss and Book Tax Loss) to the extent such allocation would
give rise to or increase an Excess Negative Balance in such Member's Capital
Account.

                  (f) In the event a Member receives with respect to a Fiscal
Year an adjustment, allocation, or distribution described in subparagraphs (4),
(5), and (6) of Regulations section 1.704-1(b)(2)(ii)(d) that results in such
Member having an Excess Negative Balance in its Capital Account, such Member
shall be allocated for such Fiscal Year (and, if necessary, for subsequent
Fiscal Years) items of income or gain in an amount and manner sufficient to
eliminate such Excess Negative Balance as promptly as possible, as provided in
Regulations section 1.704-1(b)(2)(ii)(d).
<PAGE>

                  (g) In the event that any fees, interest, or other amounts
paid to a Member or affiliate of a Member pursuant to this Agreement or to any
agreement between the Company and the Member or affiliate providing for the
payment of such amounts, and deducted by the Company, whether in reliance on
sections 162, 163, 707(a), and/or 707(c) of the Code or otherwise, on its
federal income tax return are disallowed as deductions to the Company in or with
respect to the Fiscal Year for which such amounts are claimed and are treated as
Company distributions, then:

                           (i) the Net Income or Net Loss, as the case may be,
for the Fiscal Year in or with respect to which such fees, interest, or other
amounts were paid shall be increased or decreased, as the case may be, by the
amount of such deduction that is so disallowed and treated as a Company
distribution; and

                           (ii) there shall be allocated to the Member who
received (or whose affiliate received) such payments, prior to the allocations
pursuant to Sections 4.02 and 4.02(b), an amount of gross income of the Company
for the Fiscal Year in or with respect to which such claimed deduction was
disallowed, equal to the amount of such deduction that was so disallowed and
treated as a Company distribution.

                  (h) Except as otherwise specifically provided in this
Agreement and as provided in the next sentence below, the distributive share of
a Member of each specific deduction and item of income, gain, loss, and credit
of the Company for federal income tax purposes for any Fiscal Year shall be the
same as such Member's proportionate share (determined as set forth in Section
4.02 and 4.03) of Net Income, Net Loss, Book Tax Gain, or Book Tax Loss, as the
case may be, for such Fiscal Year. Notwithstanding the foregoing, any income
recognized pursuant to sections 1245 and 1250 of the Code and any investment
credit recapture recognized pursuant to section 47 of the Code shall be
allocated among the Members in the same proportions as the depreciation
deductions and investment credits giving rise to such income or recapture were
allocated among such Members and their respective predecessors in interest.
<PAGE>

                  (i) It is the intent of the Members that each Member's
distributive share of income, gain, loss, and credit (or items thereof) shall be
determined and allocated in each Fiscal Year in accordance with this Section
4.07 to effect the distributions in the manner contemplated by Sections 4.05 and
4.06 to the extent permitted by Code section 704(b) and the applicable
Regulations. In order to achieve the contemplated distributions provided for in
Sections 4.05 and 4.06, the Managing Member is authorized and directed to
allocate income, gain, loss, and credit (or items thereof) with respect to any
Fiscal Year in a manner different from that otherwise provided for in this
Section 4.07 if, and to the extent that, allocating income, gain, loss, and
credit (or items thereof) in a manner provided for in this Section 4.07 either
would not achieve the intended economic result desired by the Members or would
not be respected under Code section 704(b) (referred to as a "new allocation").
The Managing Member is authorized to make a new allocation under this Section
4.07(i) only after having determined both (i) that the new allocation either
more accurately effects the distributions contemplated by the Members as set
forth in Section 4.05 and 4.06 or is not inconsistent with those distributions
and (ii) that the new allocation will not have a material adverse effect on the
economic interests of the Members (including, without limitation, causing them
to recognize income that they would not otherwise be required to recognize or to
lose the benefit of deductions that they otherwise would have been permitted to
recognize). New allocations by the Managing Member in accordance with this
Section 4.07(i) shall not require the consent of the other Members.

         SECTION 4.08. Contributed Property; Reevaluations Pursuant to Section
704(b) Regulations.

         In the event that any property contributed to the Company or revalued
pursuant to the provisions of Regulations section 1.704-1(b)(2)(iv)(f) has a
Carrying Value that differs from the Adjusted Basis of such property at the time
of its contribution or revaluation, any income, depreciation, gain, or loss with
respect to such property shall, solely for tax purposes, be allocated among the
Members in a manner that takes such difference into account and is consistent
with Code section 704(c), the Regulations thereunder, and Regulations section
1.704-1(b)(2)(iv)(f)(4), 1.704-1(b)(2)(iv)(g), and 1.704-1(b)(4)(i). The
allocations made pursuant to this Section 4.08 shall be made solely for tax
purposes and shall not affect or in any way be taken into account in computing
any Member's Capital Account or share of Net Income, Net Loss, Book Tax Gain,
Book Tax Loss, or other allocations or distributions under this Agreement.

         SECTION 4.09.  Withholding Taxes and Reporting Obligations.

                  (a) The Company is authorized and directed to withhold from or
pay on behalf of any Member the amount of federal, state, local, or foreign
taxes that the Managing Member reasonably determines that the Company is
required to withhold or pay with respect to any amount distributable or
allocable to such Member pursuant to this Agreement, including, without
limitation, any taxes required to be paid by the Company pursuant to section
1441, 1442, 1445, or 1446 of the Code. Any amount so withheld or paid on behalf
of a Member shall constitute an advance by the Company to such Member that shall
be secured by the Member's Membership Interest. An advance to a Member pursuant
to this Section 4.09(a) shall be repaid to the Company, in whole or in part, as
reasonably determined by the Managing Member in its sole discretion, either (i)
out of any distributions from the Company which the Member may be or become
entitled to receive, or (ii) by the Member in cash upon demand by the Company.

                  (b) The Members agree to cooperate fully with all efforts of
the Company to comply with its tax withholding and information reporting
obligations and to provide the Company with such information as the Managing
Member may reasonably request from time to time in connection with such
obligations. Any Member or permitted transferee of a Membership Interest that
fails to comply with this Section 4.09(b) shall be liable to the Company for the
amount of any taxes, penalties, and interest for which the Company becomes
liable as a result of any such failure.

                                    ARTICLE V

                  (b) Meetings and Actions.

                           (i) Meetings. The Members shall meet at least once
each Fiscal Year at the principal offices of the Company or at such other place
as may be fixed by the Managing Member (unless such meeting shall be waived by
all of the Members), upon ten (10) days' notice to all Members in writing or by
telephone or facsimile transmission. Members may participate in a meeting of the
Members by means of conference telephone or similar communications equipment by
means of which all persons participating in the meeting can hear each other, and
such participation in a meeting shall constitute presence in person at the
meeting.

                           (ii) Quorum. No action may be taken at a meeting of
the Members unless a quorum consisting of each of the Members are present in
person or by proxy.

                           (iii) Action by Written Consent. Any action to be
taken by the Members may be taken without a meeting if consents in writing
setting forth the action so taken are signed by each of the Members.

                           (iv) Voting. Each Member shall be entitled to vote

permitted by law from and against any and all losses, claims, demands, costs,
damages, liabilities (joint or several), expenses of any nature (including
attorneys' fees and disbursements), judgments, fines, settlements, and other
amounts arising from any and all claims, demands, actions, suits, or
proceedings, whether civil, criminal, administrative or investigative, in which
the Indemnitee may be involved, or threatened to be involved, as a party or
otherwise, arising out of or incidental to the business or activities of or
relating to the Company, regardless of whether the Indemnitee continues to be a
Member, the Managing Member or an Affiliate thereof at the time any such
liability or expense is paid or incurred; provided, however, that this provision
shall not eliminate or limit the liability of an Indemnitee (i) for any breach
of the Indemnitee's duty of loyalty to the Company or its Members, (ii) for acts
or omissions which involve gross negligence, intentional misconduct or a knowing
violation of law, or (iii) for any transaction from which the Indemnitee
received any improper personal benefit.

                  (b) Expenses incurred by an Indemnitee in defending any claim,
demand, action, suit, or proceeding subject to this Section 5.03 shall, from
time to time, upon request by the Indemnitee be advanced by the Company prior to
the final disposition of such claim, demand, action, suit, or proceeding upon
receipt by the Company of an undertaking by or on behalf of the Indemnitee to
repay such amount, if it shall be determined in a judicial proceeding or a
binding arbitration that such Indemnitee is not entitled to be indemnified as
authorized in this Section 5.03.
<PAGE>

                  (c) The indemnification provided by this Section 5.03 shall be

agreement, vote of the Members, as a matter of law or equity or otherwise, both
as to an action in the Indemnitee's capacity as a Member, the Managing Member or
any Affiliate thereof, and as to an action in another capacity, and shall
continue as to an Indemnitee who has ceased to serve in such capacity and shall
inure to the benefit of the heirs, successors, assigns, and administrators of
the Indemnitee.

                  (d) The Company may purchase and maintain insurance on behalf
of the Managing Member and such other Persons as the Managing Member shall

be incurred by such Persons in connection with the offering of interests in the
Company or the business or activities of the Company, regardless of whether the
Company would have the power to indemnify such Persons against such liability
under the provisions of this Agreement.

                  (e) An Indemnitee shall not be denied indemnification in whole
or in part under this Section 5.03 or otherwise by reason of the fact that the
Indemnitee had an interest in the transaction with respect to which the
indemnification applies if the transaction was otherwise permitted or not
expressly prohibited by the terms of this Agreement.

                  (f) The provisions of this Section 5.03 are for the benefit of

under the Act.

                  The death, retirement, resignation, expulsion, bankruptcy or
dissolution of any Member or the occurrence of any other event that terminates

establishment of reasonable reserves therefor; and

                  (b) any remaining assets to the Members in proportion to their

Member shall have first offered the Class A Member the right of first refusal to
acquire the Membership Interest of the Class B Member on the same terms and
conditions as the Class B Member is prepared to transfer the Class B Member's
Membership Interest to a third party and the Class A Member shall have failed to
