the Second Closing occurs prior to December 1, 1999, Charter will manage the

         (2) Section 7.3 of the Original Agreement is hereby amended and
restated in its entirety to read as follows:

         7.3       Employees.

                   7.3.1 Except as set forth in this Section 7.3.1, each Party
         may, but shall have no obligation to employ or offer employment to, any
         employee of the other Party's Cable Business. Within 30 days after the
         date of execution of this Agreement, each Party shall provide to the
         other a list of all employees of its Systems (collectively for each
         Party, its "System Employees") as of a recent date, showing the
         original hire date, the then-current positions and rates of
         compensation and whether the employee is subject to an employment
         agreement, a collective bargaining agreement or represented by a labor
         organization. Within 60 days after the date of execution of this
         Agreement (but in no event less than 30 days after receipt of such
         list), or such other date as the Parties may agree, the Party receiving
         such list will provide to the other in writing a list of the other's
         System Employees such Party or its Affiliates will employ following the
         Closing or, in the case of Charter's System Employees in Indiana,
         following the termination of the Management Agreement (the Closing
         Date, or in the context of Charter's System Employees in Indiana, the
         date of termination of the Management Agreement is referred to herein
         as the "Transfer Cutoff Date"), subject only to the evaluations
         permitted by this Section. Each Party agrees, and shall cause its
         appropriate Affiliates, to cooperate in all reasonable respects with
         the other Party to allow the other Party or its Affiliates to evaluate
         its System Employees to make hiring decisions. In this regard, each
         Party shall have the opportunity to make such appropriate prehire
         investigation of each of such other Party's System Employees, as it
         deems necessary, including, subject to obtaining the consent of such
         System Employee, the right to review personnel files and conduct
         background checks and the right to interview such employees during
         normal working hours so long as such interviews are conducted after
         notice to the other Party and do not unreasonably interfere with the
         other Party's operations. Each Party will use its good faith efforts to
         obtain the consent of each of its System Employees to allow the other
         Party to review personnel files and to conduct background checks in
         connection with the foregoing. Each Party or its Affiliates may, if it
         wishes, condition any offer of employment upon the employee's passing a
         pre-placement physical examination


                                        3
<PAGE>   4
         (including drug screening test) and the completion of a satisfactory
         background check. The Party requesting such examination shall bear the
         expense of such examination but the other Party shall, upon reasonable
         notice, cooperate in the scheduling of such examinations so long as the
         examinations do not unreasonably interfere with the other Party's
         operations. As of the Transfer Cutoff Date, each Party shall have no
         obligation to the other Party, its Affiliates or to the other Party's
         employees, with regard to any employee it has determined not to hire.
         Notwithstanding any of the foregoing, each Party agrees not to solicit
         for employment, without the written consent of the other, any employee
         listed on SCHEDULE 7.3 or any other employee of the other Party whose
         position is System manager or higher.

                   7.3.2 Each Party, or its appropriate Affiliate, will pay to
         all of its System Employees all compensation, including salaries,
         commissions, bonuses, deferred compensation, severance (to the extent
         applicable), insurance, vacation (except for accrued vacation time (not
         to exceed four weeks) and sick time (not to exceed 10 days) included in
         the calculation of such Party's Adjusted Value under the Common
         Agreement), and other compensation or benefits to which they are
         entitled for periods prior to the Transfer Cutoff Date, including all
         amounts, if any, payable on account of the termination of their
         employment.

                   7.3.3 Each Party, or its appropriate Affiliate, will be
         responsible for maintenance and distribution of benefits accrued under
         any employee benefit plan (as defined in ERISA) maintained by such
         Party, or its appropriate Affiliate, pursuant to the provisions of such
         plan and any Legal Requirements. Neither Party will assume any
         obligation or liability for any such accrued benefits or any fiduciary
         or administrative responsibility to account for or dispose of any such
         accrued benefits under any employee benefit plans maintained by the
         other Party or any Affiliate. In the event that a transferor Party
         determines that the transactions contemplated by this Agreement will
         not permit a distribution to be made to a Hired Employee (as defined
         below) from the transferor Party's tax qualified plan in accordance
         with Section 401(k)(10) of the Code then the other Party may accept a
         plan-to-plan transfer of Hired Employees' plan benefits to its own tax
         qualified plan. If there is no plan-to-plan transfer, in order to
         permit a transferor Party, or its appropriate Affiliate, to make
         distributions to any former System Employee of such Party who becomes a
         Hired Employee of the other Party of the balance of such employee's
         401(k) account in the transferor Party's or its Affiliate's tax
         qualified plan, if any, as soon as legally permitted, each transferee
         Party shall notify the other Party of the date of termination of such
         employee's employment with the transferee Party for any reason.


                                        4
<PAGE>   5
                   7.3.4 All claims and obligations under, pursuant to or in
         connection with any welfare, medical, insurance, disability or other
         employee benefit plans of a Party or any Affiliate or arising under any
         Legal Requirement affecting employees of such Party or any Affiliate
         incurred on or before the Transfer Cutoff Date or resulting from or
         arising from events or occurrences occurring or commencing on or before
         the Transfer Cutoff Date will remain the responsibility of such Party,
         or the appropriate Affiliate, whether or not such employees are hired
         by the other Party as of or after the Transfer Cutoff Date. Neither
         Party will have or assume any obligation or liability under or in
         connection with any such plan of the other Party or any Affiliate of
         the other Party.

                   7.3.5 Each Party, or its appropriate Affiliate, will remain
         solely responsible for, and will indemnify and hold harmless the other
         from and against all Losses arising from or with respect to, all
         salaries and all severance, vacation (except for accrued vacation time
         and sick time included in the calculation of such Party's Adjusted
         Value under the Common Agreement), medical, holiday, continuation
         coverage and other compensation or benefits to which its employees may
         be entitled, whether or not such employees may be hired by the other
         Party or any Affiliate of the other Party, as a result of their
         employment by such Party or any Affiliate of such Party on or prior to
         the Transfer Cutoff Date, the termination of their employment on or
         prior to the Transfer Cutoff Date, the consummation of the transactions
         contemplated hereby or pursuant to any applicable Legal Requirement or
         otherwise relating to their employment prior to the Transfer Cutoff
         Date. Any liability under WARN with regard to any employee terminated
         on or prior to the Transfer Cutoff Date, or not hired by the other
         Party on or after the Transfer Cutoff Date, shall, as a matter of
         contract between the Parties, be the responsibility of the Party or its
         Affiliates by which the employee was employed prior to the Transfer
         Cutoff Date. Each Party and its Affiliates shall cooperate with the
         other Party and its Affiliates, if requested, in the giving of WARN
         notices on behalf of the other.

                   7.3.6 Notwithstanding anything to the contrary herein, each
         Party shall:

                            (a) credit each System Employee of the other Party
         who is offered on or prior to the Transfer Cutoff Date employment by
         such Party and becomes an employee of such Party after the Transfer
         Cutoff Date (a "Hired Employee") the amount of vacation time (to a
         maximum of four weeks) and sick time (to a maximum of 10 days) accrued
         by him or her as a System Employee of the transferor Party through and
         including the Transfer Cutoff Date to the extent the transferor Party's
         System Value is decreased pursuant to Section 2.2(c)(ii) of the Common
         Agreement in the case of IPSE System Employees who become employees of
         any Charter Party


                                        5
<PAGE>   6
         or its Affiliates and Section 2.2(c)(ii) of the Common Agreement in the
         case of Charter System Employees who become employees of IPSE or its
         Affiliates, provided, however, that if any Hired Employee has accrued
         vacation time and/or sick time in excess of four weeks or 10 days,
         respectively, then the transferor Party shall, and shall cause its
         appropriate Affiliate to, pay to such employee the amount of such
         excess and the transferee Party shall not assume any liability or
         obligation in respect of such excess;

                            (b) permit each Hired Employee to participate in
         such Party's employee benefit plans to the same extent as similarly
         situated employees of such Party and their dependents are permitted to
         participate;

                            (c) given each Hired Employee credit for such
         employee's past service with the other Party and its Affiliates as of
         the Transfer Cutoff Date (including past service with any prior owner
         or operator of the other Party's Systems or Cable Business) for
         purposes of eligibility and vesting under such Party's employee benefit
         and other plans to the same extent as other similarly situated
         employees of such Party;

                            (d) not subject any Hired Employee to any waiting
         periods or limitations on benefits for pre-existing conditions under
         such Party's employee benefit plans, including any group health and
         disability plans, except to the extent such employees were subject to
         such limitations under the employee benefit plans of such other Party
         or any Affiliate of such other Party; and

                            (e) credit each Hired Employee under any group
         health plan for any deductible amount previously met by such Hired
         Employee as of the Transfer Cutoff Date under any of the group health
         plans of the transferor Party or any of its Affiliates.

                   7.3.7 If a transferee Party discharges any Hired Employee
         without cause within one hundred twenty days after Transfer Cutoff
         Date, then such transferee Party shall pay severance benefits to such
         Hired Employee in accordance with such transferor Party's severance
         benefit plan. For purposes of this SECTION 7.3.7, "cause" shall have
         the meaning set forth in the transferee Party's employment policies,
         procedures or agreements applicable to such transferee Party's
         employees who are situated similarly to the discharged Hired Employee.

                   7.3.8 If a transferor Party has, or acquires, a duty to
         bargain with any labor organization, then such transferor Party will
         (i) give prompt written notice of such


                                        6
<PAGE>   7
         development to the other Party, including notice of the date and place
         of any negotiating sessions as they are planned or contemplated and
         permit the other Party to have a representative present at all
         negotiating sessions with such labor organization and at all meetings
         preparatory thereto (including making the transferee Party's
         representative a representative of the transferor Party's delegation if
         required by the labor organization) and (ii) not, without the
         transferee Party's written consent, enter into any Contract with such
         labor organization that purports to bind the transferee Party,
         including any successor clause or other clause which would have this
         purpose or effect. Each Party (as a transferor Party) acknowledges and
         agrees that the other Party has not agreed to be bound, and will not be
         bound, without an explicit assumption of such liability or
         responsibility by the transferee Party, by any provision of any
         collective bargaining agreement or similar Contract with any labor
         organization to which the transferor Party or any of its Affiliates is
         or may become bound.

                   7.3.9 Nothing in this SECTION 7.3 or elsewhere in this
         Agreement shall be deemed to make any employee of either Party a third
         party beneficiary of this Agreement.

                   7.3.10 Notwithstanding any other provision of this Agreement,
         in respect of wages paid with respect to the calendar year in which the
         Transfer Cutoff Date falls to employees of Charter who after the
         Transfer Cutoff Date become employees of IPSE, or vice versa, IPSE and
         Charter agree to comply, and to cause their respective affiliates to
         comply, with the alternative procedures set forth in Section 5 of
         Revenue Procedure 96-60 and shall cooperate, and shall cause their
         respective affiliates to cooperate, with each other in complying with
         such procedures.

         (3) Section 7.11 (Use of Name and Logo) of the Original Agreement is
hereby amended to add the following sentence as the penultimate sentence
thereof:

         Such 180-day period will be extended with respect to the Charter
         Systems located in Indiana to expire 180 days after the termination of
         the Management Agreement.

         (4) Section 7.12 of the Original Agreement is hereby amended and
restated in its entirety to read as follows:

         7.12 Transitional Billing Services. Charter will provide to IPSE, upon
         written request delivered a reasonable amount of time in advance and to
         the extent reasonably practicable, access to and the right to use its
         billing system computers, software and related fixed assets in
         connection with the Systems acquired by IPSE


                                        7
<PAGE>   8
         for a period of up to 150 days following the Closing (or in the case of
         the Charter Systems in Indiana, for a period of up to 150 days
         following termination of the Management Agreement) to allow for
         conversion of existing billing arrangements, including billing and
         related arrangements regarding internet access services being provided
         to customers of a Charter System prior to the assumption by IPSE of the
         day-to-day management of such System ("Transitional Billing Services").
         All Transitional Billing Services will be provided on terms and
         conditions reasonably satisfactory to each Party; provided, however,
         that the amount to be paid by IPSE will not exceed the out-of-pocket
         cost to Charter of providing such Transitional Billing Services.

         (5) Section 9.2 of the Original Agreement is hereby amended to add the
following subsection 9.2.11:

3. OWNERSHIP AND OPERATION OF CHARTER RETAINED ASSETS. Charter will retain
ownership and risk of loss of the Charter Retained Assets until the Second
Closing, at which time, subject to the terms of this Amendment, Charter will
transfer the Charter Retained Assets to IPSE. The provisions of the Original
Agreement, including Sections 2.1 and 12.14, are deemed amended to reflect such
delay in transfer of ownership and risk of loss. To the extent applicable to the
Charter Retained Assets, Charter will continue to comply with the provisions of
Section 7.2 of the Original Agreement until consummation of the Second Closing.

4. FRANCHISE CONSENTS. Section 7.5.5 of the Original Agreement is hereby deleted
in its entirety.

         (1) At the Closing, (i) Charter will transfer and assign to IPSE all of
the Charter Transferred Assets, (ii) Charter will partially assign to IPSE all
Charter Shared Assets to the


                                        8
<PAGE>   9
extent necessary to permit IPSE or its agents to operate the Charter Transferred
Assets and conduct Charter's Cable Businesses with respect to the Charter
Transferred Assets as they are being operated and conducted on the Closing Date,
and (iii) IPSE will assume all of IPSE's Assumed Obligations and Liabilities
other than those obligations arising under the Charter Retained Franchises or
with respect to the Charter Retained Assets or the Retained System (the "Charter
Retained Liabilities"). IPSE hereby waives its conditions to Closing relating to
the delivery of the Charter Retained Assets and the obtaining of Required
Consents for the transfer of the Charter Retained Franchises and consents to the
partial assignment of the Charter Shared Assets at the Closing as contemplated
in this Agreement.

         (2) Article 8 of the Original Agreement is hereby amended to add the
following Sections 8.3 and 8.4:

         8.3 Conditions of IPSE's Obligations under the Second Closing. The
         obligations of IPSE to consummate the transactions contemplated by this
         Agreement to be consummated at the Second Closing will be subject to
         the satisfaction, at or before the Second Closing, of the following
         conditions, one or more of which may be waived by IPSE:

                   8.3.1 Accuracy of Representations and Warranties. The
         representations and warranties of Charter in this Agreement and in the
         Transaction Documents delivered at the Second Closing regarding the
         Charter Retained Assets, without giving effect to any materiality
         qualification contained therein, are true, complete and accurate on and
         as of the date hereof and at and as of the Second Closing with the same
         effect as if made at and as of the Second Closing, except to the extent
         that all misstatements, omissions and inaccuracies, in the aggregate,
         do not have material adverse effect on the Charter Assets, Charter's
         Cable Businesses, the operations, condition (financial or otherwise) or
         results of operations of the Charter Systems taken as a whole, or on
         the ability of any Charter Party to perform its obligations under this
         Agreement.

         contemplated by this Agreement or any Transaction Document to occur at
         the Second Closing.

         conditions set forth in SECTIONS 8.3 AND 8.4 (other than SECTIONS 8.3.3
         AND 8.4.2). The transactions to be consummated at the Second Closing
         shall be deemed to have been consummated at the time (the "Second
         Closing Time") on the date (the "Second Closing Date") as mutually
         agreed upon by the Parties.

         9.5 Charter's Delivery Obligations at the Second Closing. At the Second

<PAGE>   12
                   9.5.5 Officer's Certificate. IPSE will have received a

                   9.5.6 Opinion of FCC Counsel. An opinion of Wiley, Rein &
         Fielding dated as of the Second Closing and substantially in the form
         of EXHIBIT C.5 of the Common Agreement and rendered with respect to the
         Retained System.

                   9.5.7 Other. Such other documents and instruments as may be
         necessary to effect the intent of this Agreement and to consummate the

         transactions contemplated hereby and as are comparable to those

6. CLOSING ADJUSTMENTS WITH RESPECT TO THE RETAINED SYSTEM. All of the
adjustments made to the Base Values (as defined in the Common Agreement) of the
Retained System pursuant to the Common Agreement shall be made to reflect the
principle that all expenses and income attributable to Charter's Cable Business
conducted through the Retained System for the period through and including the
Second Closing Date are for the account of Charter, and all expenses and income
attributable to such Cable Business for the period after the Second Closing Date
are for the account of IPSE. Notwithstanding the foregoing, solely for purposes
of calculating the Charter Actual Revenues and the Charter Shortfall Adjustment
Amount, each as described in the Common Agreement, the Charter Retained Assets
shall be


                                       12
<PAGE>   13
deemed to have been transferred to IPSE as of the Closing. The Preliminary
Report (as defined in the Common Agreement) delivered with respect to the
Charter Systems will not include any adjustments related to the working capital,
liabilities, capital expenditures and other assets and liabilities of the
Retained System. If the Second Closing occurs prior to the delivery of the Final
Report (as defined in the Common Agreement) related to the Charter Systems, then
the Final Report will include all adjustments to the Base Value of the Retained
Systems as of the Second Closing Date, to the extent such adjustments are
required to be made under the Common Agreement. If the Second Closing has not
occurred prior to the delivery of the Final Report with respect to the Charter
Systems, then such Final Report will not include any adjustments related to the
working capital, liabilities, capital expenditures and other assets and
liabilities of the Retained System, and Charter will prepare and deliver to IPSE
a Final Report with respect to the Retained System no later than 90 days after
the Second Closing, which Final Report will be prepared in accordance with the
requirements set forth in the Common Agreement.

7.       FAILURE OF SECOND CLOSING.

         (1) If the City of Columbus, Indiana, and the County of Bartholomew,
Indiana, each have not consented to the transactions contemplated by the
Agreement on or before November 5, 1999, IPSE may elect by written notice to
Charter to receive, in lieu of the Charter Retained Assets, such other property
as may be mutually acceptable to the Parties (the "Charter Replacement Assets").
The Parties agree to negotiate in good faith the terms of an amendment to the
Agreement pursuant to which IPSE will acquire the Charter Replacement Assets on
terms substantially equivalent to the terms upon which IPSE has agreed to
acquire the Charter Retained Assets; provided that subject to the terms and
conditions of such amendment, the Second Closing will occur not later than the
earlier of (i) 180 days from the date of the Closing and (ii) the due date
(including extensions) for the federal Tax return for IPSE for the taxable year
in which the Closing occurs (the "Replacement Date"). Such amendment will
provide that, if the Second Closing has not occurred on or before the
Replacement Date, IPSE may elect to receive from Charter cash in an amount equal
to $88,202,130 in lieu of the Charter Replacement Assets.

         (2) Notwithstanding the foregoing, IPSE will not be required to acquire
the Charter Replacement Assets or to amend the Agreement as described in Section
7(a) unless IPSE is satisfied in its reasonable discretion following due
diligence of the Charter Replacement Assets that as of a common date on or after
the Closing Date the Charter Replacement Assets are substantially equivalent in
value to the Charter Retained Assets by "asset class" as defined under Section
1031 of the Code and the Treasury Regulations promulgated thereunder. In the
event that IPSE is not so satisfied, it may elect to receive from Charter cash
in an amount equal to $88,202,130 in lieu of the Charter Retained Assets.


                                       13
<PAGE>   14
If IPSE makes such an election to receive cash, Charter shall pay such amount by
one or more wire transfers of immediately available funds to the Qualified
Intermediary or such other payee and at such account as may be designated in
written instructions delivered to Charter by IPSE, within three Business Days
after receipt of such election and wire instructions.

         (3) In the event IPSE makes an election to receive the Charter
Replacement Assets or cash under this Section 7,

                   1.       IPSE, at its discretion, may elect to require
                            Charter to assign to IPSE at no additional cost that
                            portion of the Charter Retained Assets that
                            constitute Charter Shared Assets; and

                   2.       the Charter Parties shall, jointly and severally,
                            indemnify and hold harmless each of IPSE and its
                            Affiliates, and their respective shareholders,
                            officers, directors, partners, employees, agents,
                            successors and assigns and any Person claiming by or
                            through any of them, as the case may be, from and
                            against 50% of all taxes, interest, penalties and
                            related costs of defense (including reasonable
                            attorneys' fees), but not including any taxes
                            resulting from payments made pursuant to the
                            indemnification obligations set forth in this
                            paragraph (collectively, "Tax Losses") incurred by
                            such indemnified parties and arising out of or
                            resulting from any claim, allegation or
                            determination (whether administrative or judicial)
                            that there will result any incremental Tax Losses in
                            excess of those computed under Section 1031 of the
                            Code as if all of the Charter Assets had been
                            transferred at the Closing; provided, however, that
                            the foregoing indemnification shall not apply if
                            IPSE elects to receive Charter Replacement Assets
                            and such receipt does not qualify as a tax-deferred
                            exchange under Section 1031 of the Code unless such
                            failure to qualify arises solely from a breach by a
                            Charter Party. For the avoidance of doubt, the
                            indemnification provided by this section shall not
                            apply to Tax Losses incurred upon the receipt of
                            Charter Assets transferred at the Closing. Such
                            indemnification shall be separate from any
                            indemnification provided under the Common Agreement
                            and will not be subject to any threshold, cap or
                            other limitation, and any amounts paid by Charter
                            pursuant to this indemnification obligation will not
                            be counted for purposes of determining the
                            application of any limitations on Charter's
                            indemnification obligations under the Common
                            Agreement.
