                  (j) to own, lease, or otherwise acquire any and all assets and
services related to the foregoing purposes and to engage in such other
activities related either directly or indirectly to the foregoing purposes as
may be necessary, advisable, or appropriate, in the opinion of the Management
Committee, for the promotion or conduct of the business of the Company.

         2.6  Actions of Company Prior to Closing.

         Notwithstanding any other provisions hereof, until the Closing, the
sole activities of the Company shall be efforts to obtain the consents and
approvals required under the Contribution Agreement and to otherwise take
actions in accordance with the terms of the Contribution Agreement to consummate
the transactions contemplated thereby. Until the Closing shall occur, there
shall be no Management Committee and all actions undertaken by or on behalf of
the Company must be executed by authorized signatories of the Managing Member
and TCI; provided that actions to be taken by the Company prior to Closing will
be taken in accordance with the terms of the Contribution Agreement and the
Managing Member and TCI shall take such actions and execute such documents as
reasonably necessary to carry out such terms.

         2.7  Certificate of Formation.

         The Managing Member shall cause the Certificate of Formation to be
filed with the Secretary of State of Delaware and shall cause the Certificate of
Formation to be filed or recorded in any other public office where filing or
recording is required or is deemed by the Management Committee to be advisable.

         2.8  Addresses of the Members.

         The respective addresses of the Members are set forth on Schedule I.

         2.9  Foreign Qualification.

         The Managing Member shall take all necessary actions to cause the
Company to be authorized to conduct business legally in all appropriate
jurisdictions, including registration or qualification of the Company as a
foreign limited liability company in those jurisdictions that provide for
registration or qualification and the filing of a certificate of limited
liability company in the appropriate public offices of those jurisdictions that
do not provide for registration or qualification.

         2.10  Tax Classification.

         Notwithstanding any other provision of this Agreement, no Member or
employee of the Company may take any action (including the filing of a U.S.
Treasury Form 8832 Entity Classification Election) that would cause the Company
to be characterized as an entity other than a partnership for federal income tax
purposes without the affirmative unanimous consent of the Members. A
determination of whether any action will have the effect described in the
preceding sentence will be based upon a declaratory judgement or similar relief
obtained from a court of competent jurisdiction, a favorable ruling from the
Internal Revenue Service, or the receipt of an opinion of counsel reasonably
satisfactory to the Members.


                                   ARTICLE 3

                                COMPANY CAPITAL

         3.1 Contributions.

                  (a) Contributions at Formation. Simultaneously with the
execution of this Agreement, the Members shall each contribute to the Company
the capital contributions specified in Schedule II hereto.

                  (b) Contributions at Closing. At the Closing, and pursuant to
the terms of the Contribution Agreement:

                           (1)      TCI will contribute or cause to be 
contributed to the Company, free and clear of all Liens (other than Permitted
Liens), the assets specified in Section 2.1 of the Contribution Agreement; and

                           (2)      Insight will contribute or cause to be 
contributed to the Company, free and clear of all Liens (other than Permitted
Liens), the assets specified in Section 2.1 of the Contribution Agreement.

                  (c) Fair Market Value of Contributions; Capital Account
Balances, Applicable Percentages. Schedule II sets forth (1) the aggregate gross
fair market value of all assets as a group to be contributed to the Company by
Insight and TCI, respectively, pursuant to Section 3.1(b); (2) the Capital
Accounts of each Member immediately after the Closing; and (3) the Percentage
Interest of each Member immediately after the Closing.

                  (d) Determining Fair Market Value of Contributed Assets.
Except as otherwise agreed to between the Members, the fair market value of any
asset contributed by a Member to the Company shall be determined for purposes of
this Agreement as follows:


                                     - 17 -



                           (1)      For purposes of this Agreement, other than 
under Article 9 and other than with respect to the assets contributed by the
Members pursuant to Sections 3.1(a) and (b), which shall have the value
specified in this Agreement, the fair market value of an asset shall be that
value agreed to by the Management Committee by unanimous vote within ten days
after any party having an interest in the determination of such value requests
such determination.

                           (2)      In the event the Management Committee is 
unable to agree on a value during such ten-day period, fair market value shall
be determined within 20 days thereafter by an investment banker mutually
selected within five days of the end of such ten-day period by the parties in
interest and such determination shall be conclusive and binding on all such
parties. Each such party shall pay its pro rata portion of the expenses of the
investment banker. If the investment banker is only able to provide a range in
which fair market value would exist, fair market value shall be the average
value of the highest and lowest values of such range.

         3.2  Additional Capital Contributions.

         There shall be no further assessments for additional Capital
Contributions by the Members to the Company, provided that this section shall
not in any way limit either Member's obligations pursuant to the Contribution
Agreement to make any payment to the Company required thereunder.

         3.3  Assumption of Liabilities.

         In accordance with the terms and conditions of the Contribution
Agreement, the Company will, at the Closing, assume and undertake to pay,
discharge, and perform those obligations and liabilities of TCI, Insight, and
their respective Affiliates that are specified in Section 4.1 of the
Contribution Agreement.

         3.4  Return of Contributions.

         Neither Member shall have the right to demand a return of all or any
part of its Capital Contribution during the term of the Company, and any return
of the Capital Contribution of either Member shall be made solely from the
assets of the Company and only in accordance with the terms of this Agreement.
No interest shall be paid to either Member with respect to its Capital
Contribution to the Company.

                 DISTRIBUTIONS; ALLOCATIONS OF PROFIT AND LOSS

         4.1 Distributions of Cash.

                  (a)      Amount and Timing of Distributions.


                                     - 18 -


                           (1)      The Company shall, with respect to each 
Fiscal Year (other than the fiscal quarter in which the Company is liquidated),
distribute to Insight, (i) at least 10 days prior to each quarterly due date for
individual estimated tax payments for the Fiscal Year, an amount equal to the
estimated Tax Amount for Insight for such quarter, computed on an annualized
basis and prorated for the cumulative number of months in the Fiscal Year that
have passed as of the end of the quarter for which such estimated Tax Amount is
being computed; and (ii) not later than 90 days after the end of such Fiscal
Year an aggregate amount equal to the Tax Amount for Insight for such Fiscal
Year (to the extent not previously distributed to Insight pursuant to the
preceding clause (i) with respect to such Fiscal Year). For purposes of making
the computation in Section 4.1(a)(1)(i) for the first, second, and third
quarters of each Fiscal Year, such computation shall be based upon the Company's
estimated taxable income for the first three, five and eight months of the
Fiscal Year, respectively. The Company shall make a pro rata distribution to TCI
in proportion to the Members' relative Percentage Interests in respect of each
distribution to Insight pursuant to the preceding sentence.

                           (2)      No cash of the Company not required to be 
distributed pursuant to Section 4.1(a)(1) or Section 11.2(d)(3) shall be
distributed except as the Members may approve pursuant to Section 7.6(p).

                  (b) Allocation of Distributions. All distributions of cash
pursuant to Section 4.1(a), Section 11.2(d)(3) or otherwise approved by the
Members shall be made to the Members in proportion to their Percentage
Interests.

                  (c)      Tax Withholding.

                           (1)      The Company shall seek to qualify for and 
obtain exemptions from any provision of the Code or any provision of state,
local, or foreign tax law that would otherwise require the Company to withhold
amounts from payments or distributions to the Members. If the Company does not
obtain any such exemption, the Company is authorized to withhold from any
payment or distribution to either Member any amounts that are required to be
withheld pursuant to the Code or any provision of any state, local, or foreign
tax law that is binding on the Company.

                           (2)      Any amount withheld with respect to any 
payment or distribution to either Member shall be credited against the amount of
the payment or distribution to which the Member would otherwise be entitled. If
the Code or any provision of any state, local, or foreign tax law that is
binding on the Company requires that the Company remit to any taxing authority
any withholding tax with respect to, or for the account of, either Member in its
capacity as a Member, the Company shall, to the extent that Company funds are
available therefor, remit the full required amount of such withholding tax to
the taxing authority and shall notify such Member in writing of its obligation
to pay to the Company such withholding tax to the extent it exceeds the amount
of any payment or distribution to which such Member would otherwise then be
entitled. Each Member shall pay to the Company, within five Business Days after
its receipt of written notice from the Company that withholding is required with
respect to such Member, any amounts required to be 


                                     - 19 -


remitted by the Company to any taxing authority with respect to such Member that
are in excess of the amount of any payment or distribution to which such Member
would otherwise be entitled. If the Company is required to remit any withholding
tax with respect to, or for the account of, either Member prior to the Company's
receipt of any payment required to be made by such Member pursuant to the
preceding sentence, the amount of the payment required to be made by such Member
shall be treated as a loan (the "Withholding Advance") from the Company to the
Member, which shall accrue interest from the date the Company is required to
remit such withholding tax until paid by such Member or credited against
payments or distributions to which such Member would otherwise be entitled as
provided in Section 4.1(c)(3) at a rate of fifteen percent per year, compounded
semi-annually.

                           (3)      Any Withholding Advance made to a Member and
any interest accrued thereon shall be credited against, and shall be offset by,
the amount of any later payment or distribution to which the Member would
otherwise be entitled (without duplication of the credit provided in the first
sentence of Section 4.1(c)(2)), with any credit for accrued and unpaid interest
as of the date such payment or distribution would otherwise have been made being
applied before any credit for the amount of the Withholding Advance. Any
Withholding Advance made to a Member and any interest accrued thereon, to the
extent it has not previously been paid by the Member in cash or fully credited
against payments or distributions to which the Member would otherwise be
entitled, shall be paid by the Member to the Company upon the earliest of (A)
the dissolution of the Company, (B) the date on which the Member ceases to be a
Member of the Company, or (C) demand for payment by the Company.

                           (4)      All amounts that are credited against 
payments or distributions to which a Member would otherwise be entitled pursuant
to this Section 4.1(c) shall be treated as amounts distributed to such Member
pursuant to Section 4.1(a) for all purposes of this Agreement.

         4.2  Allocations of Net Profit and Net Loss.

                  (a) Allocations of Net Profit and Net Loss. Except as provided
in Section 4.2(b), Net Profit and Net Loss for each Fiscal Year (or portion
thereof) shall be allocated between the Members in proportion to their
Percentage Interests.

                  (b) Allocations of Net Profit and Net Loss Following
Dissolution. Notwithstanding Section 4.2(a), following the dissolution of the
Company pursuant to Section 11.1, beginning in the Fiscal Year in which such
dissolution occurs or beginning in any Fiscal Year prior to the Fiscal Year in
which such dissolution occurs if the Company's Federal income tax return for
such prior Fiscal Year has not yet been required to be filed (not including
extensions), items of income and gain, loss, and deduction shall be allocated
between the Members so as to cause the credit balances in the Members' Capital
Accounts to be in proportion to their Percentage Interests.


                                     - 20 -


         4.3  Special Provisions Regarding Allocations of Profit and Loss.

                  (a) Minimum Gain Chargeback. Notwithstanding any other
provision of this Article 4, if there is a net decrease in Company Minimum Gain
for any Fiscal Year, each Member shall be specially allocated items of Company
income and gain for such Fiscal Year (and if necessary for succeeding Fiscal
Years) in an amount equal to such Member's share of the net decrease in Company
Minimum Gain, determined in accordance with Treasury Regulations Section
1.704-2(g); provided, however, that this Section 4.3(a) shall not apply to the
extent the circumstances described in Treasury Regulations Sections
1.704-2(f)(2), 1.704-2(f)(3), 1.704- 2(f)(4), or 1.704-2(f)(5) exist.
Allocations made pursuant to the preceding sentence shall be made in proportion
to the respective amounts required to be allocated to each Member pursuant
thereto. The items of Company income and gain to be allocated pursuant to this
Section 4.3(a) shall be determined in accordance with Treasury Regulations
Section 1.704-2(f)(6). This Section 4.3(a) is intended to comply with the
minimum gain chargeback requirement in Treasury Regulations Section 1.704-2(f)
and shall be interpreted consistently therewith.

                  (b) Member Minimum Gain Chargeback. Notwithstanding any other
provision of this Article 4 except Section 4.3(a), if during any Fiscal Year
there is a net decrease in Member Nonrecourse Debt Minimum Gain, each Member
with a share of that Member Nonrecourse Debt Minimum Gain (determined in
accordance with Treasury Regulations Section 1.704-2(i)(5)) as of the beginning
of such Fiscal Year must be allocated items of Company income and gain for the
Fiscal Year (and, if necessary, for succeeding Fiscal Years) equal to that
Member's share of the net decrease in the Member Nonrecourse Debt Minimum Gain
(determined in accordance with Treasury Regulations Section 1.704-2(i)(4));
provided, however, that this Section 4.3(b) shall not apply to the extent the
circumstances described in the third and fifth sentences of Treasury Regulations
Section 1.704-2(i)(4) exist. Allocations pursuant to the preceding sentence
shall be made in proportion to the respective amounts required to be allocated
to each Member pursuant thereto. The items of Company income and gain to be
allocated pursuant to this Section 4.3(b) shall be determined in accordance with
Treasury Regulations Section 1.704-2(i)(4). This Section 4.3(b) is intended to
comply with the minimum gain chargeback requirement in Treasury Regulations
Section 1.704-2(i)(4) and shall be interpreted consistently therewith.

                  (c) Qualified Income Offset. If a Member unexpectedly receives
any adjustments, allocations, or distributions described in Treasury Regulations
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), items of Company income and gain shall be specially
allocated to such Member in an amount and manner sufficient to eliminate, to the
extent required by the Treasury Regulations, the Adjusted Capital Account
Deficit of such Member as quickly as possible; provided, however, that an
allocation pursuant to this Section 4.3(c) shall be made if and only to the
extent that such Member would have an Adjusted Capital Account Deficit after all
other allocations provided for in this Article 4 have been tentatively made as
if this Section 4.3(c) were not in this Agreement. Allocations made pursuant to
the preceding sentence shall be made in proportion to the respective amounts
required to be allocated to each Member pursuant thereto.


                                     - 21 -



                  (d) Gross Income Allocation. If a Member has a deficit Capital
Account at the end of any Fiscal Year that is in excess of the sum of (1) the
amount such Member is obligated to restore to the Company pursuant to Treasury
Regulations Section 1.704-1(b)(2)(ii)(c), (2) the amount such Member is deemed
to be obligated to restore pursuant to the penultimate sentence of Treasury
Regulations Section 1.704-2(g)(1), and (3) the amount such Member is deemed to
be obligated to restore pursuant to the penultimate sentence of Treasury
Regulations Section 1.704-2(i)(5), such Member shall be specially allocated
items of Company income and gain in the amount of such excess as quickly as
possible; provided, however, that an allocation pursuant to this Section 4.3(d)
shall be made if and only to the extent that such Member would have a deficit
Capital Account in excess of such sum after all other allocations provided for
in this Article 4 have been tentatively made as if Section 4.3(c) and this
Section 4.3(d) were not in this Agreement. Allocations made pursuant to the
preceding sentence shall be made in proportion to the respective amounts
required to be allocated to each Member pursuant thereto.

                  (e) Nonrecourse Deductions. Nonrecourse Deductions for any
Fiscal Year or other period shall be specially allocated between the Members in
proportion to their Percentage Interests.

                  (f) Member Nonrecourse Deductions. Any Member Nonrecourse
Deductions for any Fiscal Year or other period shall be specially allocated to
the Member that bears the economic risk of loss with respect to the Member
Nonrecourse Debt to which such Member Nonrecourse Deductions are attributable in
accordance with Treasury Regulations Section 1.704- 2(i).

                  (g) Section 754 Adjustment. To the extent any adjustment to
the adjusted tax basis of any asset of the Company pursuant to Code Section
734(b) or Code Section 743(b) is required, pursuant to Treasury Regulations
Section 1.704-1(b)(2)(iv)(m), to be taken into account in determining Capital
Accounts, the amount of such adjustment shall be treated as an item of gain (if
the adjustment increases the basis of the asset) or loss (if the adjustment
decreases such basis), and such gain or loss 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.

                  (h) Excess Nonrecourse Liabilities. For purposes of
determining a Member's proportionate share of the "excess nonrecourse
liabilities" of the Company within the meaning of Treasury Regulations Section
1.752-3(a)(3), each Member's interest in Company profits shall be deemed to be
equal to such Member's Percentage Interest.

                  (i) Curative Allocations. The allocations set forth in this
Article 4 (other than Section 4.3(g), Section 4.3(h), and this Section 4.3(i))
(the "Regulatory Allocations") are intended to comply with certain requirements
of the Treasury Regulations. The Members intend that, to the extent possible,
all Regulatory Allocations shall be offset either with other Regulatory
Allocations or with special allocations of other items of Company income, gain,
loss, or deduction pursuant to 


                                     - 22 -


this Section 4.3(i). Therefore, notwithstanding any other provision of this
Article 4 (other than the Regulatory Allocations), offsetting special
allocations of Company income, gain, loss, or deduction shall be made so that,
after such offsetting allocations are made, each Member's Capital Account
balance is, to the extent possible, equal to the Capital Account balance such
Member would have had if the Regulatory Allocations were not part of this
Agreement and all Company items were allocated pursuant to Section 4.2. In
making such offsetting special allocations, future Regulatory Allocations under
Section 4.3(a) and Section 4.3(b) that, although not yet made, are likely to
offset Regulatory Allocations made under Section 4.3(e) and Section 4.3(f),
shall be taken into account.

         4.4  Tax Allocations: Code Section 704(c).

                  (a) In accordance with Code Section 704(c) and the Treasury
Regulations thereunder, income, gain, loss, and deduction with respect to any
property contributed to the capital of the Company shall, solely for tax
purposes, be allocated between the Members 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 initial Gross Asset Value using the traditional
allocation method described in Treasury Regulations Section 1.704-3(b).

                  (b) If the Gross Asset Value of any asset of the Company is
adjusted pursuant to paragraph (ii) of the definition of Gross Asset Value,
subsequent allocations of income, gain, loss, and deduction with respect to such
asset shall take account of any variation between the adjusted basis of such
asset for federal income tax purposes and its Gross Asset Value in the same
manner as under Code Section 704(c) and the Treasury Regulations thereunder.

                  (c) Allocations pursuant to this Section 4.4 are solely for
purposes of federal, state, and local taxes and shall not affect, or in any way
be taken into account in computing, either Member's Capital Account or share of
Net Profit, Net Loss, other items, or distributions pursuant to any provision of
this Agreement.

         4.5  Allocation in Event of Transfer.

         If an interest in the Company is transferred in accordance with Article
8 or 9 of this Agreement, the Net Profit and Net Loss of the Company and each
item thereof, and all other items attributable to the transferred interest for
such Fiscal Year, shall be divided and allocated between the transferor and the
transferee pursuant to the interim closing of the Company books method set forth
in Treasury Regulation Section 1.706-1(c)(2)(ii) unless the parties otherwise
agree. This Section shall apply for purposes of computing a Member's Capital
Account and for federal income tax purposes.

         4.6  Alternative Allocations.

         The Management Committee is authorized and directed to allocate items
of income, gain, loss, or deduction arising in any Fiscal Year differently from
the manner that is otherwise provided 


                                     - 23 -


for in this Agreement if, and to the extent that, the Management Committee
believes that the allocation of items of income, gain, loss, or deduction in the
manner otherwise provided for in this Agreement would cause the credit balances
in the Members' Capital Accounts not to be in proportion to their Percentage
Interests immediately prior to any distributions pursuant to Section 11.2(d)(3)
if the Company were dissolved and terminated on the last day of such Fiscal
Year. Any allocation that is made pursuant to this Section 4.6 shall be deemed
to be a complete substitute for any allocation that is otherwise provided for in
this Agreement and no amendment to this Agreement shall be required.


                                   ARTICLE 5

                    AUTHORITY OF THE MANAGING MEMBER; OTHER
                       MATTERS AFFECTING MANAGING MEMBER

         5.1  Authority of Managing Member.

         The Managing Member agrees that, except for the designation and removal
of Representatives by the Managing Member pursuant to Section 7.2 hereof, or as
otherwise expressly provided herein (including as provided in Section 2.6) or in
the Management Agreement, the Managing Member acting alone shall not give any
consent on any matter or take any other action as the Managing Member,
including, without limitation, acting on behalf of or binding the Company with
respect to any matter in respect of which approval by the Management Committee
or the Members is required by the provisions of this Agreement or the Act,
unless such consent, matter or other action shall first have been adopted or
approved by the Management Committee or the Members, as the case may be, in
accordance with the provisions of this Agreement or the Act as applicable.

         5.2  No Personal Liability.

         The Managing Member shall not have any personal liability for the
repayment of the Capital Contributions of any other Member; provided that the
Managing Member shall promptly return to the Company or to the Member or Members
entitled thereto any distributions received by the Managing Member in excess of
those to which the Managing Member is entitled under this Agreement.

         5.3 Management Agreement.

         The Company and Insight (or its designated Affiliate) shall enter into
the Management Agreement effective as of the Closing. Insight shall be entitled
to the payments and reimbursements set forth therein.


                                     - 24 -


         5.4  Resignation as Managing Member.

                  (a) Insight may not resign as the Managing Member without the
consent of TCI (subject to the rights of transfer set forth elsewhere in this
Agreement and it being understood that no transfer permitted by the terms of
this Agreement shall be deemed to be a resignation for any purpose), other than
upon the dissolution and winding up of the Company in accordance with the
provisions of Article 11. If TCI consents to such resignation, the Company shall
dissolve in accordance with the provisions of Article 11 unless, within ninety
days after the resignation of Insight as the Managing Member:

                           (1)      TCI and Insight elect to continue the 
business of the Company and TCI elects, effective as of the date of the
resignation of Insight as the Managing Member, to become the new Managing
Member; or

                           (2)      TCI and Insight elect to continue the 
business of the Company, TCI elects not to become the new Managing Member, and
TCI and Insight agree to the appointment, effective as of the date of the
resignation of Insight as the Managing Member, of one or more new Managing
Members.

                  For purposes of this Agreement, the term "resignation" does
not include the happening of any event described in Section 18-304(a) or (b) of
the Act, and no Member shall cease to be a Member solely upon the happening of
such event(s); provided, that upon the happening of any such event that results
in the appointment of a trustee, receiver or liquidator of the Member or of all
or substantially all of such Member's properties and the loss by the Member of
its management authority with respect to all or substantially all of its
properties, then (x) all Representatives of the affected Member shall be deemed
to have resigned from the Management Committee and such Member shall have no
further right to designate any Representatives; and (y) no consent of such
Member or its Representatives required under any provision of this Agreement
shall any longer be required and the other Member shall be entitled to grant all
such consents and take all actions relating to the Company and its business.

                  (b) If the Company is continued pursuant to Section 5.4(a)
following the resignation of Insight as the Managing Member, Insight shall
continue to be a Member of the Company, but not a Managing Member, and TCI shall
have the right to appoint three Representatives to the Management Committee and
Insight shall have the right to appoint two Representatives to the Management
Committee, provided that any such change in the identity of the Managing Member
and the composition of the Management Committee shall be subject to and
conditioned upon receipt of all necessary governmental approvals and other
material third party consents. The resignation of Insight as the Managing Member
shall not alter the allocations and distributions to be made to the Members
pursuant to this Agreement.

                  (c) Without limiting any other rights or remedies that the
Company or TCI may have at law or in equity, upon any resignation by Insight as
the Managing Member in violation of 


                                     - 25 -


this Agreement (it being understood and agreed that no transfer permitted by the
terms of this Agreement shall be deemed to be a resignation for any purpose),
then, notwithstanding any other provision of this Agreement to the contrary (1)
all representatives of the Managing Member shall be deemed to have resigned from
the Management Committee and the Managing Member shall have no further right to
designate any representatives; and (2) no consent of the Managing Member or its
representatives required under any provision of this Agreement shall any longer
be required and TCI shall be entitled to grant all such consents and take all
actions relating to the Company and its business.

         5.5  Tax Matters Member.

                  (a) The Managing Member is hereby designated as the Tax
Matters Member of the Company, as provided in Treasury Regulations pursuant to
Code Section 6231 and analogous provisions of state law. Each Member, by the
execution of this Agreement, consents to such designation of the Tax Matters
Member and agrees to execute, certify, acknowledge, deliver, swear to, file, and
record at the appropriate public offices such documents as may be necessary or
appropriate to evidence such consent.

                  (b) To the extent and in the manner provided by applicable law
and Treasury Regulations, the Tax Matters Member shall furnish the name,
address, profits interest, and taxpayer identification number of each Member and
any Transferee to the Secretary of the Treasury or his delegate (the
"Secretary").

                  (c) The Tax Matters Member shall notify each Member of any
audit that is brought to the attention of the Tax Matters Member by notice from
the Internal Revenue Service, and shall forward to each Member copies of any
written notices, correspondence, reports, or other documents received by the Tax
Matters Member in connection with such audit within ten Business Days following
its notification by the Internal Revenue Service or its receipt, as the case may
be. The Tax Matters Member shall provide TCI with reasonable advance notice of
administrative proceedings with the Internal Revenue Service, including any
closing conference with the examiner and any appeals conference.

                  (d) The Tax Matters Member shall give the Members written
notice of its intent to initiate judicial review, file a request for
administrative adjustment on behalf of the Company, extend the period of
limitations for making assessments of any tax against a Member with respect to
any Company item, or enter into any agreement with the Internal Revenue Service
that would result in the settlement of any alleged tax deficiency or other tax
matter, or to any adjustment of taxable income or loss or any item included
therein, affecting the Company or any Member. The Tax Matters Member shall not
take any such action if TCI elects within thirty days after its receipt of the
Tax Matters Member's notice to require that the Tax Matters Member refrain from
taking such action.


                                     - 26 -


                  (e) Subject to the foregoing provisions of this Section 5.5,
the Tax Matters Member is hereby authorized, but not required:

                           (1)      to enter into any settlement with the 
Internal Revenue Service or the Secretary with respect to any tax audit or
judicial review, in which agreement the Tax Matters Member may expressly state
that such agreement shall bind the other Members, except that such settlement
agreement shall not bind either Member that (within the time prescribed pursuant
to the Code and Treasury Regulations thereunder) files a statement with the
Secretary providing that the Tax Matters Member shall not have the authority to
enter into a settlement agreement on the behalf of such Member;

                           (2)      if a notice of a final administrative 
adjustment at the Company level of any item required to be taken into account by
a Member for tax purposes (a "final adjustment") is mailed to the Tax Matters
Member, to seek judicial review of such final adjustment, including the filing
of a petition for readjustment with the Tax Court, the District Court of the
United States for the district in which the Company's principal place of
business is located, or elsewhere as allowed by law, or the United States Claims
Court;

                           (3)      to intervene in any action brought by any 
other Member for judicial review of a final adjustment;

                           (4)      to file a request for an administrative
adjustment with the Secretary at any time and, if any part of such request is
not allowed by the Secretary, to file a petition for judicial review with
respect to such request;

                           (5)      to enter into an agreement with the Internal
Revenue Service to extend the period for assessing any tax that is attributable
to any item required to be taken into account by a Member for tax purposes, or
an item affected by such item; and

                           (6)      to take any other action on behalf of the 
Members (with respect to the Company) or the Company in connection with any
administrative or judicial tax proceeding to the extent permitted by applicable
law or Treasury Regulations.

                  (f) The Company shall indemnify and reimburse the Tax Matters
Member for all expenses (including legal and accounting fees) incurred pursuant
to this Section 5.5 in connection with any administrative or judicial proceeding
with respect to the tax liability of the Members. The payment of all such
reasonable expenses shall be made before any distributions are made to the
Members. The taking of any action and the incurring of any expense by the Tax
Matters Member in connection with any such proceeding, except to the extent
provided herein or required by law, is a matter in the sole discretion of the
Tax Matters Member and the provisions on limitations of liability of the
Managing Member and indemnification set forth in Article 12 shall be fully
applicable to Insight in its capacity as the Tax Matters Member.


                                     - 27 -


                  (g) Any Member that receives a notice of an administrative
proceeding under Code Section 6233 relating to the Company shall promptly notify
the Tax Matters Member of the treatment of any Company item on such Member's
federal income tax return that is or may be inconsistent with the treatment of
that item on the Company's return.

                  (h) Either Member that enters into a settlement agreement with
the Secretary with respect to any Company item shall notify the Tax Matters
Member of such agreement and its terms within thirty days after its date, and
the Tax Matters Member shall notify the other Members of the settlement
agreement within thirty days of such notification.


                                   ARTICLE 6

                               STATUS OF MEMBERS

         6.1  No Management and Control.

         Except as expressly provided in this Agreement, no Member (other than
the Managing Member) shall take part in or interfere in any manner with the
control, conduct, or operation of the Company or have any right or authority to
act for or bind the Company or to vote on matters relating to the Company.

         6.2  Limited Liability.

         No Member shall be bound by or personally liable for the expenses,
liabilities, or obligations of the Company. In no event shall any Member be
required to make up a deficiency in its Capital Account upon the dissolution and
termination of the Company.

         6.3  Return of Distributions of Capital.

         A Member may, under certain circumstances, be required by law to return
to the Company, for the benefit of the Company's creditors, amounts previously
distributed. No Member shall be obligated by this Agreement to pay those
distributions to or for the account of the Company or any creditor of the
Company. However, if any court of competent jurisdiction holds that,
notwithstanding the provisions of this Agreement, a Member must return or pay
over any part of those distributions, the obligation shall be that of such
Member alone and not of any other Member. Any payment returned to the Company by
a Member or made directly by a Member to a creditor of the Company shall be
deemed a Capital Contribution by such Member.

         6.4  Specific Limitations.

         No Member shall have the right or power to: (a) (i) resign as a Member
(subject to the rights of transfer set forth elsewhere in this Agreement and
subject to Section 5.4(a) with respect to the Managing Member) or (ii) reduce
its Capital Contribution except as a result of the dissolution of the


                                     - 28 -


Company or as otherwise provided by law, (b) bring an action for partition
against the Company or any assets of the Company, (c) cause the termination and
dissolution of the Company, except as set forth in this Agreement, or (d) demand
or receive property other than cash in return for its Capital Contribution.
Except as otherwise set forth in this Agreement or in any agreement permitted to
be entered into under this Agreement with respect to the purchase, redemption,
retirement, or other acquisition of Membership Interests, no Member shall have
priority over any other Member either as to the return of its Capital
Contribution or as to Net Profit, Net Loss, or distributions. Other than upon
the termination and dissolution of the Company as provided by this Agreement,
there has been no time agreed upon when the Capital Contribution of any Member
will be returned.


                                   ARTICLE 7

                  (a) Except as otherwise expressly provided for herein
(including as provided in Section 2.6 and Section 5.1) or in the Management
Agreement, the business of the Company shall be managed by the Management
Committee pursuant to the provisions of this Agreement. The Management Committee
shall have exclusive authority and full discretion with respect to the
management of the business of the Company, subject to the provisions of the
Management Agreement; provided, however, any power of the Management Committee
may also be exercised by the unanimous action of the Members.

                  (b) All decisions of the Management Committee shall be by
resolution duly adopted in accordance with the provisions of this Agreement. The
Management Committee may delegate such general or specific authority to the
Managing Member and the officers of the Company as it from time to time
considers desirable, and the Managing Member and the officers of the Company may
exercise the authority granted to them, subject to any restraints or limitations
imposed by the Management Committee and the provisions of Sections 7.5 and 7.6
and any other express provisions of this Agreement. The authority granted to the
Managing Member pursuant to the Management Agreement shall be deemed a
delegation of authority by the Management Committee pursuant to this Section.

         7.2  Appointment and Removal of Representatives.

                  (a) The Management Committee shall consist of five
Representatives, three Representatives to be appointed by Insight and two
Representatives to be appointed by TCI. The initial Representatives are
specified in Schedule III. The Chairman and Secretary of the Management
Committee shall be chosen by the Management Committee.


                                     - 29 -


                  (b) Each Member shall use its good faith efforts to designate
its Representatives as promptly as is reasonably practicable so that the
Committee shall at all times contain the number of Representatives provided for
in Section 7.2(a).

                  (c) Either Member may at any time, by written notice to the
other Member, remove its Representatives, with or without cause, and substitute
Representatives to serve in their stead. No Representative shall be removed from
office, with or without cause, without the consent of the Member that designated
him.

                  (d) If any Representative is unwilling or unable to serve as
such or is removed from office by the Member that designated him, before the
transaction of any other business by the Management Committee, such Member shall
designate a successor to such Representative.

                  (e) The written notice of the Member appointing a
Representative shall in each case set forth such Representative's business
address and business telephone number.

                  (f) Each Member shall promptly give written notice to the
other Member of any change in the business address or business telephone number
of any of its Representatives.

                  (g) No compensation of, or expenses incurred by, the
Representatives incident to their duties and responsibilities as such under this
Agreement shall be paid by, or charged to, the Company.

         7.3  Meetings of the Management Committee.

         The Management Committee shall hold one regular meeting each quarter at
such time and place as shall be determined by the Management Committee. Special
meetings of the Management Committee may be called at any time by any
Representative upon not less than three Business Days' prior notice. Except as
otherwise determined by the Management Committee, all special and regular
meetings of the Management Committee shall be held at the principal office of
the Company.

         7.4  Procedural Matters.

                  (a) Each Representative shall have one vote in all matters
presented to the Management Committee for decision or approval. At all meetings
of the Management Committee, except as otherwise expressly provided for in this
Agreement, the affirmative vote of a majority of the Representatives, present at
such meeting in person or by proxy, shall be required for all actions and
decisions of the Management Committee. If a majority of the Representatives are
not present in person or represented by proxy at any meeting, the
Representatives present may adjourn the meeting from time to time, without
notice other than an announcement at the meeting, until a majority of the
Representatives shall be present or represented.


                                     - 30 -


                  (b) Unless waived in writing by all of the Representatives
(before or after a meeting) at least three Business Days' prior notice of any
meeting shall be given to each Representative. Such notice shall state the
purpose for which such meeting has been called.

                  (c) Each Representative entitled to vote at a meeting of the
Management Committee or to express consent to any action in writing without a
meeting or to express consent to any action pursuant to any other provision of
this Agreement may authorize another Representative or Person to act for him by
proxy. To be effective such proxy shall be presented at the meeting at which
such proxy is to be used or shall be presented with the writing pursuant to
which any action is taken or consent is given pursuant to such proxy, but no
proxy shall be valid after a period of three years from its date, unless the
proxy provides for a longer period.

                  (d) Any action required or permitted to be taken by the
Management Committee may be taken without a meeting if the number of
Representatives required hereunder to consent to such action, consent in writing
to such action. Such consent shall have the same effect as a vote of the
Management Committee. Prompt notice of any written action taken without the
consent of all Representatives shall be given to all non-consenting
Representatives following the taking of such action. Members of the Management
Committee shall have the right to participate in a meeting of the Management
Committee by means of a conference telephone or similar communications equipment
by means of which all Representatives participating in the meeting can hear each
other and be heard, and such participation shall constitute presence in person
at the meeting.

                  (e) The Management Committee shall cause to be kept a book of
minutes of all of its meetings in which there shall be recorded the time and
place of each such meeting, whether regular or special, and if special, by whom
called, the notice thereof given, the names of those present, and the
proceedings thereof.

         7.5  Matters Requiring TCI Approval.

         Notwithstanding any provision in this Agreement to the contrary, and in
addition to any other consent or approval that may be required by the express
terms of this Agreement, without the consent of TCI, which may be withheld by
TCI in its sole discretion, the Company shall not take, and the Management
Committee shall have no authority to cause the Company to, or cause or permit
any Subsidiary to, consummate an Asset Disposition if such Asset Disposition
would result in the allocation of income or gain to TCI pursuant to Section 4.4
and Code Section 704(c), except upon the liquidation and dissolution of the
Company in accordance with Articles 9 and 11; provided, however, that the
limitations of this paragraph shall not apply to any pledging of assets by any
Person to secure any Indebtedness of such Person permitted by this Agreement or
to any disposition of assets upon the exercise of any rights granted by such a
pledge.

addition to any other consent or approval that may be required by the express
terms of this Agreement, the Company shall not take, and the Management
Committee shall have no authority to cause the Company to take, or cause or
permit any Subsidiary to take, any of the following actions without the consent
of Insight and TCI:

Agreement); or

                  (d) enter into any transaction with either Member or any
Affiliate of either Member unless the transaction is in the ordinary course of

(except that (1) the Management Committee may, without the separate consent of
each of Insight and TCI, cause the Company to take action pursuant to Section
7.19 of the Contribution Agreement subject to the terms and conditions thereof,

Members pursuant to Section 3.1(b) 


                                     - 33 -


shall not require any additional approval of the Members, or (B) in the
geographic portion of the State of Indiana that is located above the bold line
drawn on the map of the State of Indiana attached hereto as Schedule IV unless
in either case any such systems or businesses that relate to any other State or
to such geographic portion of the State of Indiana that is located above the
bold line drawn on such map were acquired in a transaction or series of

than twenty percent of the total assets (as determined by cash flow, the number
of subscribers or such other reasonable method, as determined by the Managing
Member in its reasonable discretion) acquired in such transaction or series of
transactions;

that the use of IP technology to provide telephone, fax, video, video
conferencing, telecommuting, virtual private networks, security and energy
management services to subscribers of the Company's cable television systems
does not constitute such conducting, engaging in, or participating in an
Internet Backbone Service and does not, subject to Section 16.1(b), require the
consent or approval of the Members pursuant to this Section 7.6(r).

         7.7  Member Consent Defined.

         For purposes of this Agreement, including Sections 7.5 and 7.6, Insight

                        TRANSFER OF MEMBERSHIP INTERESTS

         8.1 Limitations on Transfers.

                  (a) Except as provided in Section 8.1(b) and 8.1(c), neither
Member may sell, assign, transfer or otherwise dispose of, or pledge,
hypothecate or otherwise encumber (any or all of the foregoing, a "Transfer")
all or any part of its Membership Interest, the profits, losses and
distributions therefrom, or any part thereof (whether voluntarily, involuntarily
or by operation of law) unless approved by the other Member, which consent shall
not be unreasonably withheld or delayed. Notwithstanding the approval of the
non-transferring Member to any Transfer by a Member, the rights of any
Transferee shall be subject at all times to the limitations set forth in Section
8.2.

                  (b) The restrictions of Section 8.1(a) shall not apply and no
consent of the other Member shall be required for:

                           (1)      a Transfer pursuant to Article 9; or

                           (2)      a Transfer to an Affiliate of such Member 
(a "Successor") so long as (A) such Transfer would not hinder or impair
consummation of any of the transactions contemplated by Article 9; (B) such
Successor, prior to such sale or transfer, becomes a party to this Agreement and
agrees to be bound by the terms and conditions hereof; and (C) in the case of a
Transfer by TCI, TCI Communications, Inc. holds and maintains, directly or
indirectly, an economic ownership in such Affiliate equal to at least 50.1% of
the economic interest in such Affiliate following such Transfer and has and
maintains, directly or indirectly, voting control of such Affiliate following
such Transfer; or

                           (3)      a Transfer pursuant to Section 8.7.

                  (c) If Insight desires to effect a Transfer that is not
permitted by the terms of this Section 8.1 except with the approval of TCI, and
if TCI grants such approval upon Insight's request, TCI shall have the right,
effective upon the Transfer by Insight, to become the Managing Member and to
appoint three Representatives to the Management Committee, and the transferee of
Insight shall have the right to appoint two Representatives to the Management
Committee, provided that any such change in the identity of the Managing Member
and the composition of the Management Committee shall be subject to and
conditioned upon receipt of all necessary governmental approvals and other
material third party consents. TCI shall exercise such right, if at all, by
giving written notice to Insight at the same time TCI grants its approval to the
Transfer by Insight. If TCI exercises such right, the transferee of Insight,
upon becoming a Member, shall not be a Managing Member, and the allocations and
distributions to be made to the Members pursuant to this Agreement shall not be
altered.


                                     - 35 -


                  (d) Notwithstanding anything in this Agreement to the
contrary, without the consent of the other Member, neither Member shall effect,
or agree to effect, any Transfer that will adversely affect or change, or is
reasonably likely to adversely affect or change, the partnership tax
classification of the Company.

         8.2  Transferees and Successors.

                  (a) Notwithstanding any provision to the contrary contained
herein, no Membership Interest may be transferred unless the Transferee or
Successor becomes a party to this Agreement, assumes all of the obligations
hereunder of its transferor and agrees to be bound by the terms and conditions
hereof in the same manner as the transferor. Upon becoming a party to this
Agreement in compliance with the terms hereof, except as otherwise provided
herein, any Transferee or Successor shall be substituted fully for, and shall
enjoy the same rights and be subject to the same obligations as, its predecessor
as a Member and/or a Managing Member hereunder as the case may be.

                  (b) If there is a permitted Transfer of a Membership Interest
under this Agreement:

                           (1)      A Transferee's or Successor's Percentage 
Interest shall equal the Percentage Interest transferred to it by the
transferring Member;

                           (2)      A Transferee's or Successor's Capital 
Account shall initially be equal to the Capital Account balance transferred to
it by the transferring Member;

                           (3)      If requested to do so by any transferring 
Member or by the Transferee or Successor by notice given to the Members, the
Company shall make an election under Section 754 of the Code (and a
corresponding election under applicable state and local law). Upon the request
of either Member, the Company shall also make a timely election under Section
754 of the Code upon a distribution of property or money to a Member.

         8.3  Transfers of Interests in Members.

                  (a) Except as provided in Section 8.3(b), TCI Communications,
Inc. agrees that it will not Transfer (whether voluntarily, involuntarily or by
operation of law) all or any part of its direct or indirect ownership interests
in TCI, without the consent of Insight.

                  (b) The restriction of Section 8.3(a) shall not apply and no
consent of Insight shall be required for a Transfer directly or indirectly by
TCI Communications, Inc. to an Affiliate of TCI Communications, Inc. so long as
(1) such Transfer would not hinder or impair consummation of any of the
transactions contemplated by Article 9; (2) such transferee, prior to such sale
or transfer, becomes a party to this Agreement and agrees to be bound by the
terms and conditions hereof; and 


                                     - 36 -


(3) TCI Communications, Inc. holds and maintains, directly or indirectly, an
economic ownership in such Affiliate equal to at least 50.1% of the economic
interest in such Affiliate following such Transfer and has and maintains,
directly or indirectly, voting control of such Affiliate following such
Transfer.

                  (c) It is understood and agreed that nothing in this Section
8.3 shall be deemed to require any consent of Insight to any proposed or actual
transfer of control (however such transfer is effected, by sale of stock or
assets, merger or consolidation or otherwise) of TeleCommunications, Inc. or TCI
Communications, Inc. or to any proposed or actual distribution to the
stockholders of Tele-Communications, Inc. of direct or indirect equity interests
in TeleCommunications, Inc.

                  (d) It is understood and agreed that nothing in this Agreement
shall be deemed to require any consent of TCI to any proposed or actual transfer
of control (however such transfer is effected, by sale of stock or assets,
merger or consolidation or otherwise) of Insight, provided, however, in the
event of such a transfer of control, TCI shall have the right, effective upon
such transfer, to become the Managing Member and to appoint three
Representatives to the Management Committee, and Insight shall have the right to
appoint two Representatives to the Management Committee, provided that any such
change in the identity of the Managing Member and the composition of the
Management Committee shall be subject to and conditioned upon receipt of all
necessary governmental approvals and other material third party consents. TCI
shall exercise such right, if at all, by giving written notice to Insight within
ten Business Days of TCI's receipt of notice that such a transfer of control is
contemplated. If TCI exercises such right, Insight, effective upon such transfer
of control, shall no longer be a Managing Member, and the allocations and
distributions to be made to the Members pursuant to this Agreement shall not be
altered.

                  (e) By executing this Agreement, TCI Communications, Inc.
represents and warrants to Insight and the Company that as of the date of this
Agreement it owns, directly or indirectly, all of the outstanding equity
interests in TCI.

         8.4  Other Consents and Requirements.

         Any Transfer must be in compliance with all requirements imposed by any
state securities administrator having jurisdiction over the Transfer and the
United States Securities and Exchange Commission and must not cause the Company
or any Subsidiary to be in violation of any Ownership Restriction.

         8.5  Assignment Not In Compliance.

         Any Transfer in contravention of any of the provisions of this Article
8 (whether voluntarily, involuntarily or by operation of law) shall be void and
of no effect, and shall neither bind nor be recognized by the Company.


                                     - 37 -


         8.6  Division of Membership Interests.

         The several rights and obligations inherent in the Capital Account and
Percentage Interest attributable to a Member's Membership Interest are
indivisible except in equal proportions, such that the assignment of a specified
percentage of a Member's Membership Interest may only represent an equal
percentage of the total Capital Account and Percentage Interest that were
attributable to such Member's Membership Interest prior to the assignment.

         8.7  Pledge of Membership Interests.

         At the request of the Management Committee, each Member agrees to
pledge its Membership Interest to secure any Indebtedness of the Company that is
permitted under this Agreement, on terms determined by the Management Committee,
so long as all Members are required to pledge their Membership Interests and the
terms of the pledge do not impose any personal liability on any Member. In
negotiating the terms of any such pledge, the Management Committee will require
that the secured party agree to enforce its rights against the Membership
Interests of the Members proportionately (based on the Percentage Interest of
each Member). If the secured party under any such pledge enforces its rights
against the Membership Interests of the Members other than proportionately, the
Members will afford each other such rights of contribution and indemnity as are
necessary to cause all liabilities, losses, and damages suffered by the Members
as a result of the exercise by the secured party of its rights under such pledge
to be borne by the Members proportionately.

         8.8  Code Section 708(b)(1)(B).

                  (a) If a Transfer by a Member of all or any portion of its
Membership Interest (other than a Transfer pursuant to Article 9) results in a
termination of the Company pursuant to Section 708(b)(1)(B) of the Code, the
transferring Member will indemnify the other Member for any additional income
tax paid by such other Member as a result of such termination (including income
tax attributable to Code Section 704(c) allocations), whether required to be
paid in or for the taxable year in which such termination occurs or in or for
any subsequent taxable year, as offset by any income tax savings to be realized
by the other Member as a result of such termination (including income tax
savings attributable to Code Section 704(c) allocations), whether realized in or
for the taxable year in which such termination occurs or in or for any
subsequent taxable year.

                  (b) If a Member desires to assign all or part of its
Membership Interest in a transaction that, if consummated at one time, would
result in the termination of the Company within the meaning of Code Section
708(b)(1)(B), such Member may elect (1) to assign immediately as much of its
Membership Interest as may then be assigned without resulting in the termination
of the Company within the meaning of Code Section 708(b)(1)(B) and (2) to assign
the remaining portion of its Membership Interest that it desires to assign as
soon thereafter as such subsequent assignment would not result in the
termination of the Company within the meaning of Code Section 708(b)(1)(B). If a
Member notifies the other Member that it has elected to assign all or part of
its 


                                     - 38 -


Membership Interest in accordance with this Section 8.8(b) specifying in its
notice the portion of its Membership Interest to be assigned immediately in
accordance with clause (1) of the preceding sentence and the portion of its
Membership Interest to be assigned subsequently in accordance with clause (2) of
the preceding sentence (the assignment of such portion, the "Deferred
Assignment"), then, if the other Member assigns all or any part of its
Membership Interest prior to the Deferred Assignment by the notifying Member and
the Deferred Assignment therefore results in the termination of the Company
within the meaning of Code Section 708(b)(1)(B), the other Member and not the
notifying Member shall be treated as the Member causing such termination for
purposes of Section 8.8(a).


                                   ARTICLE 9

                                BUY/SELL RIGHTS

         9.1 Commencement of Buy/Sell Process.

                  (a) At any time after the fifth anniversary of the Closing
(subject to Section 9.1(b)), either TCI or Insight may elect to commence the

process described in this Article 9 by giving written notice (the "Exit Notice")
of its election to commence the process described in this Article 9 to the
Non-Initiating Member. The Exit Notice shall also specify the Initiating
Member's determination of the fair market value of all of the assets of the
Company as of the date the Initiating Member delivers the Exit Notice (it being
understood and agreed that to the extent the Company has any Subsidiaries, in
making the determination of the value of the Company, the Subsidiaries shall be
taken into account) (such determination, the "Stated Value of the Company").

                  (b)      A Member may not elect to commence the process 
described in this Article 9:

                           (1)      at any time within twelve months of
delivering a prior Exit Notice to the Non-Initiating Member pursuant to Section
9.1(a); or

                           (2)      at any time within six months of the 
effectiveness of a valid notice of postponement delivered by either Member
pursuant to Section 9.2; or

                           (3)      at any time following the delivery of an
Exit Notice by the other Member pursuant to Section 9.1(a) and prior to such
time, if any, that (A) the Initiating Member and the Non-Initiating Member agree
to abandon the purchase and sale of Membership Interests commenced by such Exit
Notice pursuant to a subsequent election pursuant to Section 9.1(c), or (B) TCI
elects to terminate (or is deemed to have elected to terminate) the purchase and
sale of Membership Interests commenced by such Exit Notice pursuant to a
subsequent election pursuant to Section 9.3(c)(2) or Section 9.5(b), or (C) the
non-defaulting Member elects to terminate the purchase and sale of Membership
Interests commenced by such Exit Notice pursuant to a subsequent election
pursuant to Section 9.7(a)(3).


                                     - 39 -


                  (c) The purchase and sale of Membership Interests pursuant to
this Article 9 may be abandoned at any time following the delivery of an Exit
Notice pursuant to Section 9.1(a) and prior to the closing thereof by agreement
between the Initiating Member and the Non- Initiating Member.

         9.2  Non-Initiating Member's Option to Postpone the Buy/Sell Process.

         Upon receipt of a valid Exit Notice from the Initiating Member pursuant
to Section 9.1, the Non-Initiating Member may elect, by giving written notice to
the Initiating Member within five Business Days of the Non-Initiating Member's
receipt of such Exit Notice, to postpone for a period of six months the first
date on which either Member may commence the process described in this Article 9
by delivering an Exit Notice, provided that each Member may exercise this option
to postpone only once during the term of the Company. If the Non-Initiating
Member fails to give a timely written notice of its election to postpone
pursuant to the preceding sentence (or if the Non-Initiating Member has already
exercised its one election to postpone), the Non- Initiating Member shall be
deemed not to have made such an election to postpone. A timely and valid
election to postpone by the Non-Initiating Member shall become effective
immediately upon its delivery to the Initiating Member, at which time the
Initiating Member's Exit Notice shall automatically be rescinded and be of no
further force and effect and neither Member shall have any further obligations
in respect of such Exit Notice and such Exit Notice shall not count against the
Initiating Member for purposes of Section 9.1(b)(1).

         9.3  TCI's Options as Non-Initiating Member.

         If TCI receives an Exit Notice from Insight pursuant to Section 9.1 and
does not make (or is deemed not to have made) an election to postpone pursuant
to Section 9.2, TCI shall elect, by giving written notice (an "Initial Election
Notice") of its election to Insight within ninety days after its receipt of the
Exit Notice, either to (1) purchase Insight's Membership Interest, or (2) sell
its Membership Interest to Insight or to otherwise effect an exit from the
Company pursuant to an Alternative Structure. If TCI makes an election pursuant
to clause (2) of the preceding sentence, TCI's Initial Election Notice shall
also specify whether TCI desires to enter into negotiations with Insight to
restructure the sale of TCI's Membership Interest or its exit from the Company
in a manner that results in tax-deferred or tax-advantaged treatment to TCI (for
example, by the purchase by the Company of assets to distribute to TCI in
redemption of TCI's Membership Interest or the distribution by the Company of
certain of its then existing assets in redemption of TCI's Membership Interest)
(an "Alternative Structure").

                  (a) Election to Purchase. Upon the timely delivery by TCI of
an Initial Election Notice pursuant to this Section 9.3 specifying its election
to purchase Insight's Membership Interest, Insight shall be obligated to sell
and TCI shall be obligated to purchase, in accordance with this Article 9, all
of Insight's Membership Interest for a cash price equal to the Equity Value of
such Membership Interest. At TCI's option, TCI may designate a financially,
legally and technically 


                                     - 40 -


qualified third party to purchase Insight's Membership Interest, provided that
TCI shall not be relieved of its obligation under this Section 9.3(a) in the
event such third party does not perform.

                  (b) Election to Sell Without Election to Negotiate Alternative
Structure. Upon the timely delivery by TCI of an Initial Election Notice
pursuant to this Section 9.3 specifying TCI's election to sell its Membership
Interest to Insight without an election by TCI to negotiate an Alternative
Structure, TCI shall be obligated to sell and Insight shall be obligated to
purchase, in accordance with this Article 9, all of TCI's Membership Interest
for a cash price equal to the Equity Value of such Membership Interest.

                  (c) Election to Sell or Exit With an Election to Negotiate
Alternative Structure. Upon the timely delivery by TCI of an Initial Election
Notice pursuant to this Section 9.3 specifying TCI's election to sell its
Membership Interest to Insight or otherwise effect an exit from the Company and
specifying TCI's election to negotiate an Alternative Structure, the Members
will negotiate in good faith and use commercially reasonable efforts (taking
into account any tax, regulatory, or economic considerations) for a reasonable
period (not to exceed sixty days) to agree on an Alternative Structure.

                           (1)      If the Members agree on an Alternative 
Structure within such sixty day period, TCI and Insight shall be obligated to
effect TCI's exit from the Company, in accordance with this Article 9 and the
terms of the Alternative Structure.

                           (2)      If the Members are unable to reach agreement
on an Alternative Structure within such sixty day period, then TCI shall elect,
by giving written notice to Insight within fifteen Business Days of the end of
such sixty day period, either to (1) sell its Membership Interest to Insight, in
which event TCI shall be obligated to sell and Insight shall be obligated to
purchase, in accordance with this Article 9, all of TCI's Membership Interest
for a cash price equal to the Equity Value of such Membership Interest, or (2)
terminate the purchase and sale process commenced pursuant to Insight's Exit
Notice, subject to Section 9.6. If TCI fails to give a timely notice to Insight
pursuant to the preceding sentence, TCI shall be deemed to have made an election
pursuant to clause (2) of the preceding sentence.

                  (d) Failure to Make a Timely Election. If TCI fails to give an
Initial Election Notice to Insight within ninety days after its receipt of
Insight's Exit Notice, TCI shall be deemed to have made an election pursuant to
either Section 9.3(a), 9.3(b) or 9.3(c) as Insight shall determine in its sole
discretion by giving written notice to TCI within five Business Days after the
end of such ninety day period.

         9.4  Insight's Options as Non-Initiating Member.

         If Insight receives an Exit Notice from TCI pursuant to Section 9.1 and
does not make (or is deemed not to have made) an election to postpone pursuant
to Section 9.2, Insight shall elect, by giving written notice (an "Initial
Election Notice") of its election to TCI within ninety days after its 


                                     - 41 -


receipt of the Exit Notice, either to (1) sell its Membership Interest to TCI,
or (2) purchase TCI's Membership Interest.

                  (a) Election to Sell. Upon the timely delivery by Insight of
an Initial Election Notice pursuant to this Section 9.4 specifying its election
to sell its Membership Interest to TCI, Insight shall be obligated to sell and
TCI shall be obligated to purchase, in accordance with this Article 9, all of
Insight's Membership Interest, for an amount in cash equal to the Equity Value
of such Membership Interest.

                  (b) Election to Purchase. Upon the timely delivery by Insight
of an Initial Election Notice pursuant to this Section 9.4 specifying its
election to purchase TCI's Membership Interest, and upon the failure (or deemed
failure) of TCI to make an election to negotiate an Alternative Structure
pursuant to Section 9.5, TCI shall be obligated to sell and Insight shall be
obligated to purchase, in accordance with this Article 9, all of TCI's
Membership Interest, for an amount in cash equal to the Equity Value of such
Membership Interest.

                  (c) Failure to Make a Timely Election If Insight fails to give
an Initial Election Notice to TCI within ninety days after its receipt of TCI's
Exit Notice, Insight shall be deemed to have made an election pursuant to either
Section 9.4(a) or 9.4(b) as TCI shall determine in its sole discretion by giving
written notice to Insight within five Business Days after the end of such ninety
day period.

         9.5  TCI's Option to Negotiate Alternative Structure.

         Upon its receipt of an Initial Election Notice from Insight pursuant to
Section 9.4 specifying Insight's election to purchase TCI's Membership Interest,
TCI may elect, by giving written notice to Insight within fifteen Business Days
of its receipt of Insight's Initial Election Notice, to enter into negotiations
with Insight to agree on an Alternative Structure. If TCI fails to give a timely
notice pursuant to the preceding sentence specifying such an election, TCI shall
be deemed not to have made such an election. Upon TCI's timely delivery of its
election to negotiate an Alternative Structure, the Members will negotiate in
good faith and use commercially reasonable efforts (taking into account any tax,
regulatory, or economic considerations) for a reasonable period (not to exceed
sixty days) to agree on an Alternative Structure.

                  (a) If the Members agree on an Alternative Structure within
such sixty day period, TCI and Insight shall be obligated to effect TCI's exit
from the Company in accordance with this Article 9 and the terms of the
Alternative Structure.

                  (b) If the Members are unable to reach agreement on an
Alternative Structure within such sixty day period, then TCI shall elect, by
giving written notice to Insight within fifteen Business Days of the end of such
sixty day period, either to (1) sell its Membership Interest to Insight, in
which event TCI shall be obligated to sell and Insight shall be obligated to
purchase, in accordance with this Article 9, all of TCI's Membership Interest
for a cash price equal to the Equity 


                                     - 42 -


Value of such Membership Interest, or (2) terminate the purchase and sale
process commenced pursuant to Insight's Exit Notice, subject to Section 9.6. If
TCI fails to give a timely notice to Insight pursuant to the preceding sentence,
TCI shall be deemed to have made an election pursuant to clause (2) of the
preceding sentence.

         9.6  Insight's Option to Require TCI to Purchase Insight's Membership 
Interest.

         If TCI elects (or is deemed to have elected) to terminate the purchase
and sale process pursuant to Section 9.3(c)(2) or Section 9.5(b), Insight may
elect, by giving written notice to TCI within five Business Days of Insight's
receipt of TCI's election to terminate (or within five Business Days of TCI's
deemed election to terminate), to require TCI to purchase Insight's Membership
Interest. Upon the timely delivery by Insight of a notice pursuant to the
preceding sentence specifying Insight's election to require TCI to purchase
Insight's Membership Interest, Insight shall be obligated to sell and TCI shall
be obligated to purchase, in accordance with this Article 9, all of Insight's
Membership Interest for a cash price equal to the Equity Value of such
Membership Interest. If Insight fails to make a timely election pursuant to the
first sentence of this Section 9.6, Insight shall be deemed to have agreed to
the termination of the purchase and sale process commenced by the Initiating
Member's Exit Notice.

         9.7  Default by Member.

                  (a) If either Member becomes obligated to purchase the other
Member's Membership Interest under this Article 9 pursuant to an Exit Notice, or
if Insight becomes obligated to effect an Alternative Structure under this
Article 9 pursuant to Section 9.3(c)(1) or Section 9.5(a), and such Member
defaults in its obligation to purchase the selling Member's Membership Interest
on the date specified in Section 9.9(a) for the closing of the purchase and sale
of the selling Member's Membership Interest or Insight defaults in its
obligation to effect an Alternative Structure, then the non-defaulting Member
may elect either:

                           (1)      to purchase the Membership Interest of the 
defaulting Member for a cash price equal to 95% of the Equity Value of such
Membership Interest and otherwise on the terms and subject to the conditions set
forth in this Article 9; or

                           (2)      to cause the Company to be liquidated and 
dissolved in accordance with Article 11; or

                           (3)      to terminate the buy/sell process commenced
by the Initiating Member's Exit Notice and continue the Company.

                  (b) The three options that may be elected by the
non-defaulting Member pursuant to Section 9.7(a) are exclusive of each other and
are exclusive of all other rights and remedies that may otherwise have been
available to the non-defaulting Member at law or equity as a result of the
defaulting Member's default.


                                     - 43 -


                  (c) The non-defaulting Member may make an election pursuant to
Section 9.7(a) by giving written notice of its election to the defaulting Member
at any time within thirty days after the date specified in Section 9.9(a) for
the closing of the purchase and sale of the non-defaulting Member's Membership
Interest or the date scheduled for closing of an Alternative Structure and prior
to such time, if any, as the defaulting Member stands ready, willing, and able
to purchase the non-defaulting Member's Membership Interest in accordance with
this Article 9 or to consummate the Alternative Structure. If the non-defaulting
Member makes a timely election pursuant to Section 9.7(a)(1), the defaulting
Member shall be obligated to sell and the non-defaulting Member shall be
obligated to purchase, in accordance with this Article 9, all of the defaulting
Member's Membership Interest.

         9.8  Removal of Insight as Member.

                  (a)      The provisions of this Section 9.8 shall apply if:

                           (1)      a court of competent jurisdiction finds that
Insight has engaged in conduct while acting as Managing Member that constitutes
either fraud against the Company or TCI or a felony involving moral turpitude
and that such conduct has resulted in material harm to the Company or TCI, and

                           (2)      the finding described in Section 9.8(a)(1) 
has not been reversed, stayed, enjoined, set aside, annulled, or suspended, and
is not the subject of any pending request for judicial review, reconsideration,
appeal, or stay, and

                           (3)      the time for filing any further request for 
judicial review, reconsideration, appeal, or stay of the finding described in
Section 9.8(a)(1) has expired.

                  (b) If each of the conditions specified in Section 9.8(a) is
satisfied, then (1) TCI shall have the power to appoint three of the five
Representatives of the Management Committee and the Managing Member shall have
the power to appoint two of the five Representatives; provided, that such change
in composition of the Management Committee shall be subject to and conditioned
upon receipt of all necessary governmental approvals and other material third
party consents and (2) TCI shall have the option to purchase all of the Managing
Member's Membership Interest in accordance with the process described in this
Section 9.8(b) and Section 9.8(c). TCI may elect to commence such process by
giving written notice of its election to Insight within ten Business Days after
the condition specified in Section 9.8(a)(3) is satisfied. Upon Insight's
receipt of TCI's notice pursuant to the preceding sentence, Insight and TCI
shall, within thirty Business Days of such receipt, negotiate in good faith to
determine the fair market value of all of the assets of the Company as of the
date TCI delivers notice to Insight pursuant to the first sentence of this
Section 9.8(b) (it being understood and agreed that to the extent the Company
has any Subsidiaries, in making the determination of the value of the Company,
the Subsidiaries shall be taken into account) (the "Fair Market Value of the

                           (1)      If Insight and TCI fail to agree upon the 
Fair Market Value of the Company within such period, then each of Insight and
TCI will select a nationally recognized investment banking firm or nationally
recognized qualified appraisal firm who will determine the Fair Market Value of
the Company within sixty days of engagement. If the average of the two
appraisals is within 1.5% of the lower of the appraisals, then the Fair Market
Value of the Company will be the average of the two appraisals. If such average
is not within 1.5% of the lower of the two appraisals, the two appraisers
selected by Insight and TCI will select a third nationally recognized investment
banking firm or a nationally recognized qualified appraisal firm who will
conduct a third appraisal, and the Fair Market Value of the Company will be
equal to the average of the two appraisals that are closest to one another,
provided that if the highest and lowest appraisals are equidistant from the
middle appraisal, then the Fair Market Value of the Company will be equal to the
middle appraisal. Each of Insight and TCI shall have the right to submit to all
appraisers a position paper with respect to valuation. Each of Insight and TCI
will bear the expenses of the firm investment banking firm or appraisal firm
that they select, and if a third investment banking firm or appraisal firm is
used, Insight and TCI will share equally the expenses of the third firm. In
conducting the appraisals, the appraisers shall assume that the value of any
business is the price at which the assets of such business as a going concern
would change hands between a willing buyer and a willing seller, on terms and
subject to conditions and costs applicable in the cable television industry
(and, if and to the extent applicable, any other industry in which the Company
or any of its Subsidiaries is engaged) and otherwise use valuation techniques
then prevailing in the cable television industry or such other industry.

                           (2)      If at the time the Fair Market Value of the 
Company is being determined pursuant to this Section 9.8 any Retained Franchises
or Exchange Retained Franchises (as defined in the Contribution Agreement) that
are required to be contributed to the Company have not been contributed to the
Company pursuant to the Contribution Agreement, then the Fair Market Value of
the Company shall be determined and calculated as if such Retained Franchises
and Exchange Retained Franchises were then owned by the Company; and if TCI
purchases Insight's Membership Interest pursuant to this Article 9, all
obligations of Insight under the Contribution Agreement with respect to any such
Retained Franchises that are Insight Retained Franchises (including obligations
to contribute the Exchange Retained Franchises to the Company upon transfer from
TCI) shall survive the removal of Insight from the Company upon the sale of its
Membership Interest subject to any conditions on such obligations.

                  (c) TCI may elect to purchase all of Insight's Membership
Interest and, upon the consummation of such purchase, to remove Insight as a
Member, by giving written notice of its election to Insight within ten Business
Days after the final determination of the Fair Market Value of the Company. Upon
the timely delivery by TCI of notice pursuant to the preceding sentence
specifying its election to purchase Insight's Membership Interest, Insight shall
be obligated to sell and TCI shall be obligated to purchase, in accordance with
this Article 9, all of Insight's Membership Interest for a cash price equal to
the Equity Value of Insight's Membership Interest. If TCI fails to give a timely
notice to Insight pursuant to the first sentence of this Section 9.8(c)
specifying its 


                                     - 45 -


election to purchase Insight's Membership Interest, TCI shall be deemed to have
made an election not to purchase Insight's Membership Interest pursuant to this
Section 9.8, in which event, subject to Sections 9.8(b) and (d), Insight shall
continue as the Managing Member.

                  (d) The rights of TCI under this Section 9.8 are in addition
to any other rights and remedies available to TCI at law or equity as a result
of any conduct by Insight described in Section 9.8(a).

         9.9  General Terms Applicable to Purchase and Sale of Membership 
Interests.

                  (a) The closing of the purchase and sale of a Member's
Membership Interest or of an Alternative Structure in accordance with this
Article 9 shall occur not later than twenty Business Days after the receipt of
all material governmental consents and approvals required in connection with the
sale of the selling Member's Membership Interest in connection with such
Alternative Structure.

                  (b) The closing of the purchase and sale of the selling
Member's Membership Interest or of the Alternative Structure in accordance with
this Article 9 shall take place at the principal office of the Company or at any
other location agreed to by Insight and TCI.

                  (c) At the closing of any purchase and sale of the selling
Member's Membership Interest or of any Alternative Structure pursuant to this
Article 9, the purchasing Member or the Company or other buyer in an Alternative
Structure shall pay or cause to be paid to the selling Member, by cash or other
immediately available funds or any other form of consideration mutually agreed
to by the selling Member and the purchasing Member or the consideration agreed
to as part of the Alternative Structure, the purchase price for the Membership
Interest being purchased and the selling Member shall deliver to the purchasing
Member (or its permitted assignee or the Company or other buyer in an
Alternative Structure) good title, free and clear of any liens (other than those
created by this Agreement and those securing financing obtained by the Company
or any Subsidiary), to the Membership Interest being sold.

                  (d) With respect to the current assets and liabilities of the
Company, the transaction costs and the reserves to be determined as part of the
Equity Value of the Membership Interest to be sold at the closing pursuant to
this Article 9, such current assets and liabilities, costs and reserves shall be
determined by mutual agreement of Insight and TCI at least five days in advance
of the date scheduled for said closing, but to the extent that as of such date
there is a good faith disagreement between the parties as to any portion of such
current assets, liabilities, costs or reserves the parties shall proceed to
closing of such purchase and sale, with closing based on matters not in dispute.
Thereafter, all matters in dispute shall be immediately referred to an
independent public accountant mutually acceptable to Insight and TCI who shall
make such determination as promptly as practicable and whose determination shall
be final and binding upon the parties. If the accountant determines that either
party is entitled to payment from the other party, the party which owes such
payment shall make it to the entitled party in cash (or in the same form of
consideration 


                                     - 46 -


as is being paid in such transaction if the parties have agreed to an
Alternative Structure) in accordance with the accountant's determination.

                  (e) The Members will cooperate in good faith and use their
respective commercially reasonable efforts to obtain as quickly as practicable
all governmental consents and approvals required in connection with the purchase
and sale of a Member's Membership Interest or an Alternative Structure pursuant
to this Article 9.

                  (f) From and after the closing, the purchasing Member will be
entitled to indemnification from the selling Member (or another creditworthy
entity reasonably acceptable to the purchasing Member) against any liabilities
of the selling Member as a Member (including without limitation, tax liabilities
of the selling Member for periods prior to the closing) for periods prior to
closing not taken into account in determining the Equity Value of the Membership
Interest purchased by the purchasing Member. The other indemnification
obligations of the selling Member to the purchasing Member shall be
substantially equivalent to its indemnification obligations to the Company
pursuant to the Contribution Agreement. On the date that is one year after the
closing under this Article 9, the selling Member shall be entitled to its
distributable share of any reserves set up pursuant to Section 11.2(d)(2) that
had not yet been used to pay any obligation or liability that relates to the
period prior to the date of closing pursuant to this Article 9 and that would
not be required to be maintained in accordance with generally accepted
accounting principles with respect to the period prior to the date of closing
pursuant to this Article 9.

                  (g) Each Member agrees that, from and after the date on which
the respective obligations of the Members to purchase and sell the selling
Member's Membership Interest or to effect an Alternative Structure become
effective in accordance with this Article 9, it will negotiate in good faith and
use commercially reasonable efforts to enter into an appropriate purchase
agreement or other agreements on reasonable terms and conditions that are
consistent with the other provisions of this Article 9 and that are otherwise
standard and customary at the time for similar transactions. The Members
recognize that the sixty day period specified in Sections 9.3(c) and 9.5 to
agree on an Alternative Structure relates to agreement on the form and material
terms of the structure and a timetable for entering into the purchase agreement
or other agreements necessary to effect the Alternative Structure, but that
additional time may be required to negotiate and enter into such agreements.

                  (h) Each Member hereby agrees that the other Member shall be
entitled to an injunction or injunctions to prevent breaches by such Member of
its obligations under this Article 9 and to enforce specifically the terms and
provisions of this Article 9 in any court of the United States or any state
having jurisdiction, in addition to any other remedy to which it is entitled at
law or in equity. If an action is brought by either Member pursuant to this
Section 9.9(h), the other Member shall waive the defense that there is an
adequate remedy at law.

                 OTHER BUSINESSES AND INVESTMENT OPPORTUNITIES

          10.1  [Intentionally Deleted].

          10.2  Limitations on Activities of the Company.

                  (a) Prior to January 31, 1999, or for such shorter period as
TCI (or its Affiliates) is bound by a similar requirement (as such requirement
is in effect on the date hereof) under that certain Parents Agreement dated as
of January 31, 1996 between TeleCommunications, Inc. and Sprint Corporation (the
"Parents Agreement"), whichever occurs first, the Company will not offer (or
promote or package any of its products or services with or act as a sales agent
for) wireline services (local or long distance) under the brand name of any Bell
Operating Company or any of GTE Corporation, AT&T Corporation, MCI
Communications Corporation, British Telecommunications, plc, WorldCom, Inc.,
Cable & Wireless plc, LCI International Inc. or Frontier Corporation or any of
their respective Affiliates; provided, however, that in no event shall this
restriction apply (1) to the extent that a Controlled Affiliate (as defined in
the Parents Agreement) of Tele-Communications, Inc. would not be subject to a
similar requirement under the Parents Agreement (as a result of any exceptions
in the Parents Agreement to the covenants of Tele-Communications, Inc. and its
Controlled Affiliates thereunder or otherwise) or (2) following the termination
of the Parents Agreement.

                  (b) Prior to January 31, 1999, or for such shorter period as
TCI (or its Affiliates) is bound by a similar requirement (as such requirement
is in effect on the date hereof) under the Parents Agreement, whichever occurs
first, the Company will not make its distribution facilities available to a
third party in connection with offering local phone service to residential
customers without making the facilities similarly available to Sprint
Corporation; provided, however, (1) the Company itself may offer local phone
service (subject to the restrictions in Section 10.2(a)) without offering its
distribution facilities to Sprint Corporation, and (2) in no event shall this
restriction apply (A) to the extent that a Controlled Affiliate (as defined in
the Parents Agreement) of Tele-Communications, Inc. would not be subject to a
similar requirement under the Parents Agreement (as a result of any exceptions
in the Parents Agreement to the covenants of Tele-Communications, Inc. and its
Controlled Affiliates thereunder or otherwise) or (B) following the termination
of the Parents Agreement.

                  (c) Prior to January 31, 1999, or for such shorter period as
TCI (or its Affiliates) is bound by a similar requirement (as such requirement
is in effect on the date hereof) under the Parents Agreement, whichever occurs
first, the Company will not make its distribution facilities available to any
Bell Operating Company or any of GTE Corporation, AT&T Corporation, MCI
Communications Corporation, British Telecommunications, plc, WorldCom, Inc.,
Cable & Wireless plc, LCI International Inc. or Frontier Corporation or any of
their respective Affiliates for high speed 


                                     - 48 -


data services without making its facilities similarly available to Sprint
Corporation; provided, however, (1) such facilities may be made available to
other third parties, including @Home, without such facilities being made
available to Sprint Corporation, and (2) in no event shall this requirement
apply (A) to the extent that a Controlled Affiliate (as defined in the Parents
Agreement) of Tele-Communications, Inc. would not be subject to a similar
restriction under the Parents Agreement (as a result of any exceptions in the
Parents Agreement to the covenants of Tele-Communications, Inc. and its
Controlled Affiliates thereunder or otherwise) or (B) following the termination
of the Parents Agreement.

                  (d) TCI represents and warrants to, and agrees with, Insight
that none of the foregoing restrictions will (1) subject to Section 10.4,
restrict the ability of Insight or its Affiliates (other than the Company) from
engaging in any of the activities specified in Sections 10.2(a), (b) and (c)
other than through the Company; or (2) restrict the Company or its Subsidiaries
from providing wireline backhaul and wireline transport of wireless
communications signals on arms length and customary terms.

          10.3  Prohibited Cross-Interests.

                  (a) Each Member agrees that, during the term of this
Agreement, neither such Member nor any Affiliate of such Member shall, directly
or indirectly, acquire any interest in any business or in any Person if the
acquisition of such interest would cause the Company or any Subsidiary to be in
violation of any Ownership Restriction.

                  (b) If, during the term of this Agreement, there is a Formal
Determination that either Member's holding of a Membership Interest causes the
Company or any Subsidiary to be in violation of any Ownership Restriction, then
the following provisions of this Section 10.3(b) shall apply. For purposes of
this Section 10.3(b), a "Formal Determination" means (i) an agreement between
Insight and TCI, (ii) a written determination by the FCC (including a
determination by staff employees of the FCC acting under delegated authority),
regardless of whether such determination is subject to administrative or
judicial review, reconsideration, or appeal (except to the extent that, so long
as a stay of any enforcement action by the FCC against the Company or any
Subsidiary as a result of any such violation of an Ownership Restriction is
effective, the Member that caused the violation specifies that any such
determination will not constitute a Formal Determination during the pendency of
any review, reconsideration, or appeal), or (iii) a decision of any court of
competent jurisdiction, regardless of whether such decision is subject to
administrative or judicial review, reconsideration, or appeal (except to the
extent that, so long as a stay of any enforcement action by the FCC against the
Company or any Subsidiary as a result of any such violation of an Ownership
Restriction is effective, the Member that caused the violation specifies that
any such decision will not constitute a Formal Determination during the pendency
of any review, reconsideration, or appeal). Insight and TCI will use their
respective good faith efforts, after consultation with legal counsel, to reach
an agreement as to whether either Member's holding of a Membership Interest
causes the Company or any Subsidiary to be in violation of any Ownership
Restriction.


                                     - 49 -


                           (1)      The Company will use reasonable efforts to 
obtain a stay of any enforcement action by the FCC against the Company or any
Subsidiary as a result of any such violation of an Ownership Restriction (and
the unanimous vote of the Members shall be required for the Company to act
otherwise), and the Members will cooperate reasonably with the Company in such
efforts, to the extent necessary to prevent such violation from having a
material adverse effect on the Company and the Subsidiaries before it is cured.
For purposes of this Section 10.3(b), a material adverse effect on the Company
and the Subsidiaries includes the loss of any license or licenses issued by the
FCC that, in the aggregate, are material to the conduct of the business of the
Company and the Subsidiaries, the imposition of any fines or forfeitures that,
in the aggregate, are material in amount, and limitations on the ability of the
Company or any Subsidiary to conduct its business in the ordinary course
consistent with its past practices.

                           (2) The Company and the Members will cooperate
reasonably with each other and negotiate in good faith with the FCC to obtain a
determination by the FCC (including a determination by staff employees of the
FCC acting under delegated authority) that certain actions proposed to be taken
by a Member or its Affiliates would cure any such violation of an Ownership
Restriction. The actions proposed to be taken by a Member or its Affiliates to
cure such violation may be those that, in such Member's judgment, are least
detrimental to such Member and its Affiliates, and may include the divestiture
of any asset or the restructuring of any investment.

                           (3)      If there is a Formal Determination that a
Member's holding of a Membership Interest causes the Company or any Subsidiary
to be in violation of any Ownership Restriction, (such Member, the "Curing
Member") agrees to take all actions reasonably necessary to cure any such
violation of an Ownership Restriction; provided, however, that:

                                    (A)     if the Company and the Members
receive a determination by the FCC (including a determination by staff employees
of the FCC acting under delegated authority) that certain actions proposed to be
taken by the Curing Member or its Affiliates would cure such violation, then, if
the Curing Member and its Affiliates take such actions, the Curing Member shall
not be required to take any other action under this Section 10.3(b) to cure such
violation until such time, if any, that there is a subsequent Formal
Determination that such actions did not cure such violation;

                                    (B) The Curing Member shall not be required
to take any action to cure such violation prior to the time that such violation
would have a material adverse effect on the Company and the Subsidiaries; and

                                    (C) The Curing Member shall not be required
to take any action to cure any violation that arose from any acquisition made by
the Company or any Subsidiary in violation of Section 10.3(c).

                           (4)      The actions that the Curing Member may be 
required to take pursuant to Section 10.3(b)(3), subject to the limitations
therein, shall include, to the extent necessary to cure 


                                     - 50 -


such violation, executing amendments to this Agreement to eliminate any right of
the Curing Member under this Agreement (other than its right to allocations of
income, its right to distributions, its rights under Section 7.5 in the case of
TCI as the Curing Member, its rights under Section 7.6, and its right to approve
any other action by the Company and the Subsidiaries if such action (A) in the
case of an action that does not uniquely affect either Member, such as an
acquisition or disposition of assets or a financing, would have a material
adverse economic effect on the Curing Member or (B) in the case of an action
that uniquely affects either Member, such as a transaction between the Company
and a Member or an Affiliate of a Member, would have an adverse economic effect
on the Curing Member).

                  (c) Neither Member will approve the acquisition, directly or
indirectly, by the Company or any Subsidiary of any interest in any business or
in any Person if such Member has actual knowledge that consummating such
acquisition would cause either Member or any Affiliate of either Member to be in
violation of any Ownership Restriction; provided that if the Managing Member
desires to cause the Company or a Subsidiary to acquire assets or an interest in
a business or any Person, and the Managing Member does not have actual knowledge
that such acquisition would cause the Company or a Subsidiary, either Member or
any Affiliate of either Member to be in violation of any Ownership Restriction,
then the Managing Member shall provide prior written notice to TCI of such
proposed acquisition at least 30 days prior to entering into a binding agreement
to effect such acquisition and if TCI notifies the Managing Member within
fifteen days of receiving such notice that such acquisition would cause the
Company or a Subsidiary or TCI to be in violation of any Ownership Restriction,
the Managing Member shall not proceed with such acquisition without first
complying with this Section 10.3(c) again, it being understood that if TCI does
not so notify the Managing Member within such fifteen day period then the
Managing Member shall be presumed not to have knowledge that such acquisition
would cause the Company or a Subsidiary, either Member or any Affiliate of
either Member to be in violation of any Ownership Restriction.

          10.4  Limitations on Other Activities of the Members.

          To the extent that Insight or a Controlled Affiliate of Insight
engages within the geographic portion of the State of Indiana that is located
below the bold line drawn on the map of the State of Indiana attached hereto as
Schedule IV in any of the activities specified in Sections 10.2(a), (b) or (c)
at a time when the Company is prohibited from engaging in such activity, other
than through the Company, for a reasonable period of time (not to exceed 120
days), after TCI (or its Affiliates) are no longer bound by the restrictive
terms of the Sprint PCS Partnership Agreement or the Parents Agreement, as
applicable to the restricted activity at issue, Insight (upon receipt of notice
from TCI of such fact and TCI's election on behalf of the Company in accordance
with this Section 10.4 to exercise its rights under this Section 10.4) and TCI
shall negotiate in good faith to provide the Company the opportunity to acquire
the business related to such activity from Insight or its appropriate Affiliate;
provided that if at such time such business has been discontinued or such assets
(or the equity interests in such Affiliate) have been sold or otherwise disposed
of, none of the parties shall have any further obligation to each other with
respect to any such acquisition opportunity. It is understood and agreed by
Insight and TCI that without limiting any other considerations 


                                     - 51 -


(including any necessary governmental or third party approvals), any such
acquisition by the Company shall be based upon the fair market value of the
business. To the extent Insight and TCI are unable for any reason to reach
agreement within such 120 day period referred to above, none of the parties
shall have any further obligation to each other with respect to any such
acquisition opportunity. TCI shall determine, acting in the best interests of
the Company, whether the Company shall exercise its rights under this Section
10.4 provided that TCI and Insight as part of reaching an agreement for the
Company to make such acquisition, shall also agree on any necessary capital
contributions and/or debt financing necessary to fund such acquisition by the
Company or any Subsidiary pursuant to this Section 10.4.

          10.5  No Other Restrictions.

          Except as specifically provided above in this Article 10, nothing in
this Agreement shall limit the ability of either Member, or any partner, member,
Affiliate, Controlled Affiliate, agent, or representative of either Member, to
engage in or possess an interest in other business ventures of any nature or
description, independently or with others, whether currently existing or
hereafter created and whether or not competitive with or advanced by the
business of the Company. Neither the Company nor the other Member shall have any
rights in or to the income or profits derived therefrom, nor shall either Member
have any obligation to the other Member with respect to any such enterprise or
related transaction.


                                   ARTICLE 11

                     DISSOLUTION AND LIQUIDATION OF COMPANY

          11.1 Events of Dissolution.

          The Company shall be dissolved upon the happening of any of the
following events:

                  (a) the failure of the Members to continue the Company in
accordance with the provisions of Section 5.4(a) after the resignation of the
Managing Member with the consent of TCI (it being confirmed, with reference to
Section 5.4(c), that the resignation of the Managing Member in violation of this
Agreement shall not cause a dissolution);

                  (b) the expiration of the term of the Company as set forth in 
Section 2.4;

                  (c) an election to liquidate and dissolve the Company made by
a non-defaulting Member pursuant to Section 9.7(a)(2);

                  (d) the sale, exchange, involuntary conversion, or other
disposition or transfer of all or substantially all of the assets of the
Company;

                  (e) upon agreement of Insight and TCI;


                                     - 52 -


                  (f) the termination of the Contribution Agreement in
accordance with its terms prior to the Closing (including, without limitation,
pursuant to Section 10.1(e) of the Contribution Agreement); or

                  (g) subject to any provision of this Agreement that limits or
prevents dissolution, the happening of any event that, under applicable law,
causes the dissolution of a limited liability company.

          11.2  Liquidation.

                  (a) Upon dissolution of the Company for any reason, the
Company shall immediately commence to wind up its affairs. A reasonable period
of time shall be allowed for the orderly termination of the Company business,
discharge of its liabilities, and distribution or liquidation of the remaining
assets so as to enable the Company to minimize the normal losses attendant to
the liquidation process.

                  (b) Liquidation of the assets of the Company shall be managed
on behalf of the Company by the "Liquidator," which shall be (1) if the Company
is being liquidated pursuant to Section 11.1(c), the non-defaulting Member, and
(2) in all other events, Insight or a liquidating trustee selected by Insight.
The Liquidator shall be responsible for soliciting offers to purchase the
entirety of the Company's assets (including equity interests in other Persons)
or portions or clusters of assets of the Company. The Liquidator shall afford
each Member an opportunity to offer to purchase any assets of the Company that
are offered for sale in connection with the liquidation of the Company to the
extent doing so would be consistent with the orderly liquidation of the Company.

                  (c) The Liquidator shall cause a full accounting of the assets
and liabilities of the Company to be taken and a statement thereof to be
furnished to each Member within thirty days after the distribution of all of the
assets of the Company.

                  (d) The property and assets of the Company and the proceeds
from the liquidation thereof shall be applied in the following order of
priority:

                           (1)      first, to payment of the debts and 
liabilities of the Company, in the order of priority provided by law (including
any loans by either Member to the Company) and payment of the expenses of
liquidation;

                           (2)      second, to setting up of such reserves as 
the Liquidator may deem reasonably necessary for any contingent or unforeseen
liabilities or obligations of the Company or any obligation or liability not
then due and payable; provided, however, that any such reserve shall be paid
over by the Liquidator into a Company account or a liquidating trust account
established for such purpose, to be held in such account for the purpose of
disbursing such reserves in payment of 


                                     - 53 -


such liabilities, and, at the expiration of such holdback period as the
Liquidator shall deem advisable, to distribute the balance thereafter remaining
in the manner hereinafter provided; and

                           (3)      finally, to payment to the Members, in 
accordance with Section 4.1(b). The distributions pursuant to this Section
11.2(d)(3) shall, to the extent possible, be made prior to the later of the end
of the Fiscal Year in which the dissolution occurs or the ninetieth day after
the date of dissolution, or such other time period which may be permitted under
Treasury Regulations Section 1.704-1(b)(2)(ii)(b).

                  (e) If in the course of the liquidation and dissolution of the
Company pursuant to this Article 11, the Liquidator determines that a sale by
all the Members to any Person of their Membership Interests, instead of a sale
by the Company and the Subsidiaries of their respective assets, would more
efficiently effect the liquidation of the Members' economic interests in the
Company or would reduce negative tax consequences to the Members and the
Company, but would not adversely affect the rights and obligations of either
Member (including the tax consequences to either Member), then each Member
agrees to sell its Membership Interest to such Person, and the Liquidator shall
have the authority, pursuant to the power of attorney granted in Section
16.7(b), to execute, acknowledge, deliver, swear to, file, and record all
agreements, instruments, and other documents that may be necessary or
appropriate to effect the sale of such Member's Membership Interest.

                  (f) Following the dissolution of the Company pursuant to
Section 11.1, the Members will use commercially reasonable efforts to structure
the liquidation of the Company in a manner that minimizes negative tax
consequences to the Members and the Company to the extent doing so would not
materially adversely affect either Member (except to the extent such Member is
adequately compensated by the other Member for such adverse effect). Any
structure agreed to by the Members pursuant to this Section 11.2(f) shall
supersede the other provisions of this Article 11 to the extent it is
inconsistent with such other provisions, but nothing in this Section 11.2(f)
shall modify or otherwise affect the other provisions of this Article 11 if the
Members are unable to agree on such a structure.

          11.3  Distribution in Kind.

          The Company shall not distribute any non-cash asset to either Member
without the consent of each Member. Any asset distributed in kind to one or more
Members shall first be valued at its fair market value to determine the gain or
loss used in determining Net Profit or Net Loss that would have resulted if such
asset were sold for such value, such gain or loss shall then be allocated
pursuant to Article 4, and the Members' Capital Accounts shall be adjusted to
reflect such gain or loss. The amount distributed and charged to the Capital
Account of each Member receiving an interest in such distributed asset shall be
the fair market value of such interest (net of any liability secured by such
asset that such Member assumes or takes subject to). The fair market value of
any asset distributed in kind in connection with the liquidation of the Company
shall be determined by an independent 


                                     - 54 -


appraiser (any such appraiser must be nationally recognized as an expert in
valuing the type of asset involved) selected by the Liquidator.

          11.4  No Action for Dissolution.

          The Members acknowledge that irreparable damage would be done to the
goodwill and reputation of the Company if either Member should bring an action
in court to dissolve the Company under circumstances where dissolution is not
required by Section 11.1. This Agreement has been drawn carefully to provide
fair treatment of all parties and equitable payment in liquidation of the
Membership Interests of both Members. Accordingly, except where liquidation and
dissolution are required by Section 11.1, each Member hereby waives and
renounces its right to initiate legal action to seek dissolution or to seek the
appointment of a receiver or trustee to liquidate the Company.

          11.5  No Further Claim.

          Upon dissolution, each Member shall look solely to the assets of the
Company for the return of its investment, and if the property of the Company
remaining after payment or discharge of the debts and liabilities of the
Company, including debts and liabilities owed to one or more of the Members, is
insufficient to return the aggregate capital contributions of a Member, no
Member shall have any recourse against any other Member.


                                   ARTICLE 12

                                INDEMNIFICATION

          12.1 General.

          The Company shall indemnify, defend, and hold harmless each Member and
their respective members, partners, officers, directors, shareholders,
employees, and agents, the employees, officers, and agents of the Company, and
the members of the Management Committee (all indemnified persons being referred
to as "Indemnified Persons" for purposes of this Article 12), from any
liability, loss, or damage incurred by the Indemnified Person by reason of any
act performed or omitted to be performed by the Indemnified Person in connection
with the business of the Company, including costs and attorneys' fees (which
attorneys' fees may be paid as incurred) and any amounts expended in the
settlement of any claims of liability, loss, or damage; provided, however, that,
if the liability, loss, damage, or claim arises out of any action or inaction of
an Indemnified Person, indemnification under this Section 12.1 shall not be
available if the action or inaction is finally adjudicated to have constituted
fraud, gross negligence, breach of fiduciary duty (which shall not be construed
to encompass mistakes in judgment or any breach of any Indemnified Person's duty
of care that did not constitute gross negligence), or willful misconduct by the
Indemnified Person; and provided, further, however, that indemnification under
this Section 12.1 shall be recoverable only from the assets of the Company and
not from any assets of the Members. The Company may pay 


                                     - 55 -


for insurance covering liability of the Indemnified Persons for negligence in
operation of the Company's affairs.

          12.2  Exculpation.

          No Indemnified Person shall be liable, in damages or otherwise, to the
Company or to either Member for any loss that arises out of any act performed or
omitted to be performed by it or him pursuant to the authority granted by this
Agreement unless the conduct of the Indemnified Person is finally adjudicated to
have constituted fraud, gross negligence, breach of fiduciary duty (which shall
not be construed to encompass mistakes in judgment or any breach of any
Indemnified Person's duty of care that did not constitute gross negligence), or
willful misconduct by such Indemnified Person.

          12.3  Persons Entitled to Indemnity.

          Any Person who is within the definition of "Indemnified Person" at the
time of any action or inaction in connection with the business of the Company
shall be entitled to the benefits of this Article 12 as an "Indemnified Person"
with respect thereto, regardless of whether such Person continues to be within
the definition of "Indemnified Person" at the time of his or its claim for
indemnification or exculpation hereunder.

          12.4  Procedure Agreements.

          The Company may enter into agreements with any of its Members,
employees, officers, and agents, any of the officers, directors, shareholders,
employees, and agents of the Managing Member, and any member of the Management
Committee or other Indemnified Person, setting forth procedures for implementing
the indemnities provided in this Article 12.

manner whatsoever, in whole or in part, except that:

                  (a) each Member shall be permitted to disclose such

reasonable opportunity to contest the necessity of disclosing such information,

                  (d) each Member shall be permitted to disclose information to
the extent necessary for the enforcement of any right of such Member arising

writing which provides the Company with an independent right of enforcement) to
be bound by the provisions of this Section 13.10,

Member and the Company as follows:

          14.1  Investment Intent.

          It is acquiring its Membership Interest with the intent of holding the
same for investment for its own account and without the intent or a view to
participating directly or indirectly in, or for resale in connection with, any
distribution of such Membership Interest within the meaning of the Securities
Act or any applicable state securities laws, and it does not intend to divide
its participation with others, nor to resell, assign, or otherwise dispose of
all or any part of its Membership Interest. In making such representation, each
Member acknowledges that a purchase now with an intent to resell by reason of
any foreseeable specific contingency, some predetermined event, or an
anticipated change in market value or in the condition of the Company would
represent a purchase with an intent inconsistent with the foregoing
representation.

          14.2  Securities Regulation.

                  (a) It acknowledges and agrees that the Membership Interest is
being issued and sold in reliance on the exemption from registration contained
in Section 4(2) of the Securities Act and exemptions contained in applicable
state securities laws, and that it cannot and will not be sold or transferred
except in a transaction that is exempt under the Securities Act and those state
acts or pursuant to an effective registration statement under those acts or in a
transaction that is otherwise in compliance with the Securities Act and those
state acts.

                  (b) It understands that it has no contract right for the
registration under the Securities Act of the Membership Interest for public sale
and that, unless such Membership Interest is registered or an exemption from
registration is available, such Membership Interest may be required to be held
indefinitely.

          14.3  Knowledge and Experience.

          It has such knowledge and experience in financial, tax, and business
matters as to enable it to evaluate the merits and risks of its investment in
the Company and to make an informed investment decision with respect thereto.


                                     - 61 -


          14.4  Economic Risk.

Membership Interest.

          This Agreement is and will remain its valid and binding agreement,
enforceable in accordance with its terms (subject, as to the enforcement of
remedies, to any applicable bankruptcy, insolvency, or other laws affecting the
enforcement of creditor's rights).

          14.6  Tax Position.

          Unless it provides prior written notice to the Company, it will not
take a position on its federal income tax return, on any claim for refund, or in
any administrative or legal proceedings that is inconsistent with any
information return filed by the Company or with the provisions of this
Agreement.

          14.7  Information.

          It has received all documents, books, and records pertaining to an
investment in the Company requested by it. It has had a reasonable opportunity
to ask questions of and receive answers concerning the Company, and all such
questions have been answered to its satisfaction.

consent of Insight and TCI.

                  (b) The Company shall prepare and file any amendment to the
Certificate of Formation that may be required to be filed under the Act as a
consequence of any amendment to this Agreement.

          15.2  Waivers.

          The observance or performance of any term or provision of this
Agreement may be waived (either generally or in a particular instance, and
either retroactively or prospectively) by the party entitled to the benefits of
such term or provision.

                                  MISCELLANEOUS

          16.1 Programming and Discounts.

                  (a) General. Subject to Section 16.1(b) and any other
particular arrangements the Members may agree to with respect to the following,
each Member will use commercially reasonable efforts to make all of the
services, programming and equipment discounts available to such Member available
to the Company.

                  (b) @Home.

                           (1)      The Members and the Company agree that,
subject to the other provisions of this Section 16.1(b) and only so long as
controlled affiliates (as used in this Section 16.1, "controlled affiliate" has
the meaning given to such term in the @Home Distribution Agreement) of a TCI
Cable Parent continue to be bound by a similar requirement, @Home will be the
exclusive provider of Exclusive Internet Services over the cable plant and
equipment of the TCI Systems and that the TCI Systems will continue to be bound
by the @Home Distribution Agreement as if such TCI Systems were "controlled
affiliates" of a TCI Cable Parent with respect to the distribution and delivery
of Exclusive Internet Services in accordance with the @Home Distribution
Agreement. In furtherance of the foregoing, subject to the other provisions of
this Section 16.1(b) and only so long as controlled affiliates of a TCI Cable
Parent continue to be bound by a similar requirement, the Company and the
Managing Member each agree that it will not provide or distribute, and will not
permit any Person other than @Home and its controlled affiliates to provide or
distribute, Exclusive Internet Services using the cable plant and equipment of
the TCI Systems, in each case without the prior written consent of TCI. The
Members and the Company acknowledge and agree that the foregoing limitations
will not be applicable to the Company's provision over the TCI Systems of other
Internet Services which do not constitute Exclusive Internet Services (including
all Internet Services which are listed as exceptions to the definition of the
term "Restricted Business" in the @Home Distribution Agreement), and with
respect to those Internet Services which do not constitute Exclusive Internet
Services, the Managing Member shall be entitled to make all determinations in
respect of the provision of such Internet Services, subject to the provisions of
this Agreement. The Members and the Company also acknowledge and agree that the
foregoing limitations are also not applicable to the Company's provision over
the Company's cable television systems other than the TCI Systems (such other
systems, the "Non-TCI Systems") of any Internet Services, whether or not they
would constitute Exclusive Internet Services with respect to the TCI Systems in
accordance with the @Home Distribution Agreement, and do not limit the right of
the Company and the Managing Member to manage and operate the Non-TCI Systems as
the Company and the Managing Member determine (but subject to the terms of this
Agreement and the Management Agreement). Without limiting the preceding
sentence, subject to the other provisions of this Section 16.1(b), the parties
agree as follows: (A) the Company and the Managing Member


                                     - 63 -


agree that they will: (1) manage and operate (and cause the manager under the
Management Agreement to manage and operate) the TCI Systems in accordance with
the terms and conditions set forth in the @Home Distribution Agreement and in
such a manner that the activities and businesses engaged in by the TCI Systems
will not violate or be in contravention of the Cable Parent Exclusivity
Provisions, or cause any TCI Cable Parent or any of its controlled affiliates to
be in violation of such Cable Parent Exclusivity Provisions, (2) provide to
@Home and its representatives such access to the cable plant and equipment of
the TCI Systems as is required in order to satisfy the TCI Cable Parents'
obligations under the @Home Distribution Agreement in respect of such TCI
Systems and as is reasonably necessary in order to distribute the @Home Service
over the cable plant and equipment of such TCI Systems, (3) cooperate with
@Home, TCI Cable Parent and their respective controlled affiliates in order to
schedule and coordinate @Home's roll-out of the @Home Service to the TCI Systems
with the upgrade of the physical cable plant and equipment of such TCI Systems,
including, without limitation, (x) providing the TCI Cable Parent and @Home with
information and periodic updates as to upgrade schedules, and (y) entering into
LCO Agreements (as defined in the @Home Distribution Agreement) in respect of
each TCI System upon the commencement of the offering of the @Home Service in
such TCI System, and (4) cooperate with the TCI Cable Parent and @Home with
respect to the operational matters relating to the distribution of the @Home
Service, including, without limitation, pricing, the programming of the Local
Area (as defined in the @Home Distribution Agreement), billing, customer service
and service offerings; and (B) (1) with respect to the timing and implementation
of Exclusive Internet Services over the TCI Systems, the Managing Member shall
consult and cooperate with the TCI Cable Parent in order to coordinate the
launch of the @Home Service over the TCI Systems as efficiently and
expeditiously as practical and (2) the TCI Cable Parent may disclose to @Home
information relating to the upgrade plans for the TCI Systems for the purpose of
coordinating the @Home build-out and the launch of the @Home Service in such
systems. Subject to the Company's and the Managing Member's compliance with the
foregoing, the TCI Cable Parent agrees that it will use its commercially
reasonable efforts to obtain for the benefit of the TCI Systems the economic and
other benefits available to a controlled affiliate of a TCI Cable Parent under
the @Home Distribution Agreement, on the same basis as, and for so long as, such
benefits are available to other controlled affiliates of the TCI Cable Parent,
including, but not limited to, the benefits available under the MFN Provision
(as defined in the @Home Distribution Agreement) and the ability to purchase
Ancillary Services (as defined in the @Home Distribution Agreement) from @Home
for the TCI Systems to the extent provided in the @Home Distribution Agreement
and as are reasonably necessary to the distribution of the Exclusive Internet
Services on the TCI Systems. TCI's obligations under the foregoing sentence will
terminate if the Company exercises its option set forth below to terminate its
obligation to manage the TCI Systems in accordance with the terms of the @Home
Distribution Agreement or if the Company enters into a separate distribution
agreement with @Home that covers the TCI Systems. In the event the


                                     - 64 -


@Home Distribution Agreement is amended or modified in such a way as would
reasonably be expected to cause the terms and conditions of the Company's
distribution of the @Home Service over the TCI Systems to be materially more
onerous to the Company than as provided in the @Home Distribution Agreement as
in effect on the date hereof, the TCI Cable Parent shall promptly notify the
Company and the Company shall then have the option to terminate its obligation
to manage the TCI Systems in accordance with the terms of the @Home Distribution
Agreement; provided that the Company's agreement not to provide or distribute,
or permit any Person to provide or distribute, any Exclusive Internet Services
using the cable plant and equipment of the TCI Systems, other than the @Home
Service, shall survive such termination. No amendment to the @Home Distribution
Agreement shall be deemed to cause the terms and conditions of the Company's
distribution of the @Home Service over the TCI Systems to be materially more
onerous to the Company (x) to the extent that such amendment or modification
does not result in such distribution being more onerous than that provided under
any separate agreement between the Company and @Home relating to the
distribution of the @Home Service to the Non-TCI Systems or (y) if the Company
consents to an amendment or modification of any separate agreement between the
Company and @Home in respect of the distribution of the @Home Service to the
Non-TCI Systems, which amendment or modification has substantially the same
effects as the proposed amendment or modification of the @Home Distribution
Agreement. For so long as the TCI Systems are included under the @Home
Distribution Agreement, to the extent the @Home Distribution Agreement is
modified in any respect (or any other event occurs) that would increase the
benefits available to (or reduces the obligations of) a controlled affiliate of
a TCI Cable Parent, the TCI Cable Parent will use its commercially reasonable
efforts to obtain for the benefit of the TCI Systems such increased benefits,
and to the extent the obligations are reduced, the TCI Cable Parent will use its
commercially reasonable efforts to cause such reduced obligations to be
applicable to the TCI Systems, in each case on the same basis as is applicable
to controlled affiliates of the TCI Cable Parent other than the TCI Systems. For
purposes of this Section 16.1(b), the TCI Systems shall, notwithstanding their
contribution to the Company, continue to be deemed to be controlled affiliates
of a TCI Cable Parent for purposes of determining the Company's satisfaction of
its obligations to operate and manage the TCI Systems in accordance with the
@Home Distribution Agreement.

                           (2)      In addition, the Company and the Managing 
Member agree to use their commercially reasonable efforts to enter into prior to
the Closing a distribution agreement for the @Home Service for the cable
television systems contributed to the Company by Insight; provided that such
obligation shall survive the Closing if such distribution agreement is not
entered into prior thereto. To the extent that TCI is not able to include the
TCI Systems under the @Home Distribution Agreement following the Closing, the
Company may enter into a distribution agreement with @Home that covers the TCI
Systems and terminate its obligation to manage the TCI Systems in accordance
with the @Home Distribution Agreement; provided, that such agreement shall be
approved by TCI as it relates to the TCI Systems and provided further that the
Company's obligations under this Section 16.1(b) to (i) have @Home be the
exclusive provider of Exclusive Internet Services over the cable plant and
equipment of the TCI Systems, (ii) not provide or distribute or permit any other
Person to provide or distribute Exclusive Internet Services using the cable
plant and equipment of the TCI Systems and (iii) manage the TCI Systems in such
a manner that the activities and business engaged in by them will not violate or
be in contravention of the Cable Parent Exclusivity Provisions will not cause
any TCI Cable Parent or its controlled affiliates to be in violation of such
provisions will continue notwithstanding such separate agreement being entered
into.


                                     - 65 -


          16.2  Cost Sharing; Reimbursement.

          If the Closing occurs, the Company shall reimburse each Member for the
out-of-pocket costs and expenses reasonably incurred by such Member (whether
incurred before or after the formation of the Company) in connection with the
formation, organization, and capitalization of the Company (including costs and
expenses incurred in arranging any proposed or consummated financing); provided,
however, such costs and expenses to be reimbursed by the Company do not include
legal fees or other expenses or costs of the Members incurred in connection with
the preparation, execution, delivery and performance of this Agreement, the
Contribution Agreement or any related agreements (other than the financing
agreements of the Company) and except as specifically provided for in the

Closing, the Company shall not reimburse either Member for any costs, which
shall be borne by the Members as provided in the Contribution Agreement.

          16.3  Additional Documents.

          At any time and from time to time after the date of this Agreement,

acknowledged, and delivered, all such additional instruments and documents, as

which the Members or their Affiliates are parties, contains the entire agreement
between the Members as to the subject matter of this Agreement. The waiver of

conditions of this Agreement.

Member, by the execution of this Agreement, irrevocably constitutes and appoints
the Liquidator its true and lawful attorney-in-fact with full power and
authority in its name, place, and stead to execute, acknowledge, deliver, swear
to, file, and record all agreements, instruments, and other documents that may
be necessary or appropriate to effect the sale of such Member's Membership
Interest pursuant to Section 11.2(e).

                  (c) The power of attorney granted pursuant to Section 16.7(b)
shall be deemed to be a power coupled with an interest, in recognition of the
fact that each of the Members under this Agreement will be relying upon the
power of the Liquidator to act as contemplated by this Agreement in any filing
and other action by it on behalf of the Company, and shall survive the
bankruptcy, death, adjudication of incompetence or insanity, or dissolution of
any Person hereby giving such powers and the transfer or assignment of all or
any part of such Person's Membership Interest; provided, however, that in the
event of a Transfer by a Member, the powers of attorney given by the transferor
shall survive such Transfer only until such time as the Transferee or Successor
shall have been admitted to the Company as a substituted Member and all required
documents and instruments shall have been duly executed, filed, and recorded to
effect such substitution.

                  (d) Each Member agrees to be bound by any actions taken by the
Liquidator acting in good faith pursuant to the power of attorney granted
pursuant to Section 16.7(b) that are consistent with and subject to the
provisions of this Agreement and hereby waives any and all defenses that may be
available to contest, negate, or disaffirm any action of the Liquidator taken in
good faith under the power of attorney granted pursuant to Section 16.7(b) that
are consistent with and subject to the provisions of this Agreement.

to all other relief granted.


                                     - 67 -

partner or member of either Member or any creditor of the Company or of either
of the Members.

          16.10  Headings.

Agreement.

          16.11  Board Approval.

such termination of the Contribution Agreement. Upon notification to Insight

under this Agreement shall no longer be subject to obtaining any such approvals.

                Insight                                    $ 327,851,078
                TCI                                          310,851,078

TCI and Insight will negotiate in good faith to reach agreement prior to Closing
on the allocation of the aggregate gross fair market value among the assets to
be contributed by them to the Company. If TCI and Insight are unable to reach
such agreement prior to Closing, then promptly following Closing they will
mutually agree on an appraiser to be hired by the Company to allocate the
aggregate gross fair market values among the assets contributed by them. Neither
TCI nor Insight will take a position that is inconsistent with the allocations
determined by such appraiser. With respect to any of the assets contributed to
the Company by Insight pursuant to Section 3.1(b) that were acquired by Insight
from TCI pursuant to the Exchange Agreement entered into by Insight and TCI on
the date hereof, Insight and TCI agree to use the allocations determined by any

IV.      Adjustments to Value of Assets and Amount of Debt Assumed:

the aggregate gross fair market value of the assets to be contributed by the
Member(s) paying such adjustment as set forth above in paragraph II shall be
decreased by the amount of such Closing Adjustment and the amount of
indebtedness to be assumed by the Company from such Member(s) at Closing as set
forth above in paragraph III shall be decreased by the amount of such Closing
