Interests from time to time (i) to reflect increases or decreases in the fair
market value of the Louisiana or Tennessee cable systems owned by the Company,

members in accordance with their Percentage Interests or number of membership
units, provided, however, that items of the Company's income and gain shall be
specially allocated among the Members at such times and in such amounts required
to satisfy the qualified income offset requirement of Treasury Regulations
Section 1.704-1(b)(2)(ii)(d). Any such special allocations shall be taken into
account in allocating items of income, gain, loss and deduction among the
Members so that, to the extent possible (without violating the qualified income
offset requirement above), the net amount of such allocations of other items and
such special allocations shall be equal to the net amount that would have been
allocated to each such Member if such special allocations had not occurred.

         (b) Except as otherwise required by the Internal Revenue Code or the
Treasury Regulations, all items of Company income, gain, loss, expense,
deduction and any other items shall be allocated among the Members for federal
income tax purposes in the same proportions as the share the corresponding items

tax purposes and its initial or adjusted book value, as the case may be, as
reflected in the Members' capital accounts in accordance with applicable
provisions of the Internal Revenue Code and the Treasury Regulations. Any
elections or other decisions relating to allocations pursuant to this Section
9(b) shall be made by the Tax Matters Member, in any manner that reasonably
reflects the purpose and intention of this Agreement. Allocations pursuant to
this Section 9(b) 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 book income, gain, loss, expense, deduction, other
items, or distributions pursuant to any provision of this Agreement.

         SECTION 10. Dissolution; Winding Up.

         (a) The Company shall be dissolved upon (i) the adoption of a plan of
dissolution by the members or (ii) the occurrence of any event required to cause
the dissolution of the Company under the Delaware Limited Liability Company Act.

         (b) Any dissolution of the Company shall be effective as of the date on
which the event occurs giving rise to such dissolution, but the Company shall
not terminate unless and until all its affairs have been wound up and its assets
distributed in accordance with the provisions of the Delaware Limited Liability
Company Act.

         (c) Upon dissolution of the Company, the Company shall continue solely
for the purposes of winding up its business and affairs as soon as reasonably
practicable. Promptly after the dissolution of the Company, the Manager shall
immediately commence to wind up the affairs of the Company in accordance with
the provisions of this Agreement and the Delaware Limited Liability Company Act.
In winding up the business and affairs of the Company, the Manager may take any
and all actions that they determine in its sole discretion to be in the best
interests of the members, including, but not limited to, any 

                                      -8-

<PAGE>   9

actions relating to (i) causing written notice by registered or certified mail
of the Company's intention to dissolve to be mailed to each known creditor of
and claimant against the Company, (ii) the payment, settlement or compromise of
existing claims against the Company, (iii) the making of reasonable provisions
for payment of contingent claims against the Company and (iv) the sale or
disposition of the properties and assets of the Company. It is expressly
understood and agreed that a reasonable time shall be allowed for the orderly
liquidation of the assets of the Company and the satisfaction of claims against
the Company so as to enable the Manager to minimize the losses that may result
from a liquidation.

         SECTION 11. Transfer. For so long as the Company has more than one
member, no member shall transfer (whether by sale, assignment, gift, pledge,
hypothecation, mortgage, exchange or otherwise) all or any part of his, her or
its limited liability company interest in the Company to any other person
without the prior written consent of each of the other members; provided,
however, that this Section 11 shall not restrict the ability of any member to
transfer (at any time) all or a portion of its limited liability company
interest in the Company to another member. Upon the transfer of a member's
limited liability company interest, the Manager shall provide notice of such
transfer to each of the other members and shall amend Exhibit A hereto to
reflect the transfer.

         SECTION 12. Admission of Additional Members. The admission of
additional members to the Company shall be accomplished by the amendment of this
Agreement and, if required by the Delaware Limited Liability Company Act.

         SECTION 13. Tax Matters. The members agree that, so long as the Company
has more than one member, it is intended that the Company shall be treated as a
partnership for purposes of United States federal, state and local income tax
laws, and further agree not to take any position or make any election, in a tax
return or otherwise, inconsistent therewith. So long as the Company is a
partnership for federal income tax purposes, the "tax matters partner" of the
Company (the "Tax Matters Member") for purposes of section 6231(a)(7) of the
Internal Revenue Code of 1986, as amended, shall be as set forth in Exhibit A,
attached hereto. The Tax Matters Member shall have the power to manage and
control, on behalf of the Company, any administrative proceeding at the Company
level with the Internal Revenue Service relating to the determination of any
item of Company income, gain, loss, deduction or credit for federal income tax
purposes. In the event that the Company becomes a sole member entity, it is
intended that for federal income tax purposes its assets be deemed to be owned
by the sole member in accordance with the applicable Treasury Regulations.

         SECTION 14. Exculpation and Indemnification.

         (a) Neither the members, the Manager, the directors, their affiliates,
nor any person who at any time shall serve, or shall have served, as a director,
officer, employee or other agent of any member or any such affiliate and who, in
such capacity, shall engage, or shall have engaged, in activities on behalf of
the Company (a "Specified Agent") shall be liable, in damages or otherwise, to
the Company or to any member for, and neither the Company nor any member shall
take any action against such members, their affiliates or any Specified Agent,
in respect of any loss which arises out of any acts or omissions performed or
omitted by it pursuant to the authority granted by this Agreement, or otherwise
performed 

                                      -9-

<PAGE>   10

on behalf of the Company, if such member, such affiliate, or such Specified
Agent, as applicable, in good faith, determined that such course of conduct was
in the best interests of the Company. Each member shall look solely to the
assets of the Company for return of his, her or its investment, and if the
property of the Company remaining after the discharge of the debts and
liabilities of the Company is insufficient to return such investment, each
member shall have no recourse against the Company, the other members or their
affiliates, except as expressly provided herein; provided, however, that the
foregoing shall not relieve any member of any fiduciary duty or duty of fair
dealing to the other members that it may have under applicable law.

         (b) In any threatened, pending or completed claim, action, suit or
proceeding to which a member, any of such member's affiliates, or any Specified
Agent was or is a party or is threatened to be made a party by reason of the
fact that such person is or was engaged in activities on behalf of the Company,
including without limitation any action or proceeding brought under the
Securities Act of 1933, as amended, against a member, any of such member's
affiliates, or any Specified Agent relating to the Company, the Company shall
indemnify and hold harmless the members, any such affiliates, and any such
Specified Agents against losses, damages, expenses (including attorneys' fees),
judgments and amounts paid in settlement actually and reasonably incurred by or
in connection with such claim, action, suit or proceeding; provided, however,
that none of the members, any of their affiliates or any Specified Agent shall
be indemnified for actions constituting bad faith, willful misconduct, or fraud.
Any act or omission by any member, any of such member's affiliates or any
Specified Agent, if done in reliance upon the opinion of independent legal
counsel or public accountants selected with reasonable care by such member, such
affiliate or such Specified Agent, as applicable, shall not constitute bad
faith, willful misconduct, or fraud on the part of such member, affiliate or
Specified Agent.

         (c) The termination of any claim, action, suit or proceeding by
judgment, order or settlement shall not, of itself, create a presumption that
any act or failure to act by a member, such member's affiliate or any Specified
Agent constituted bad faith, willful misconduct or fraud under this Agreement.

         (d) Any such indemnification under this Section 14 shall be recoverable
only out of the assets of the Company and not from the members.

         SECTION 15. Miscellaneous.

         (a) A member's limited liability company interest may be evidenced by a

other form as the Manager may approve).

         (b) The terms and provisions set forth in this Agreement may be
amended, and compliance with any term or provision set forth herein may be
waived, only by a written instrument executed by each member. No failure or
delay on the part of any member in exercising any right, power or privilege
granted hereunder shall operate as a waiver thereof, nor shall any single or
partial exercise of any such right, power or privilege preclude any

other or further exercise thereof or the exercise of any other right, power or
privilege granted hereunder.

         (c) This Agreement shall be binding upon and inure to the benefit of
the members and their respective successors and assigns.

         (d) This Agreement shall be governed by, and construed in accordance
with, the laws of the State of Delaware, without regard to any conflicts of law
principles that would require the application of the laws of any other
jurisdiction.

         (e) In the event that any provision contained in this Agreement shall
be held to be invalid, illegal or unenforceable for any reason, the invalidity,
illegality or unenforceability thereof shall not affect any other provision
hereof.

         (f) This Agreement may be executed in one or more counterparts, each of
which shall be deemed an original, but all of which together shall constitute
one and the same instrument.
