     (d)  Notes.
          -----

          (i)   The indebtedness of the Company to each Bank under this

Bank in the form of Exhibit A hereto. The original principal amount of each
                    ---------
Bank's Note from the Company will be the amount identified in Section 1.1(b)
hereof as its respective Commitment Amount; provided, however, that
notwithstanding the face amount of each such Note, the Company's liability under
each such Note shall be limited at all times to its aggregate actual
indebtedness, including principal, interest and fees, and obligations under

outstanding in connection with the applicable Bank's Commitment hereunder.

          (ii)  The Notes issued hereunder collectively amend and restate in
their entireties, and are substituted for, the Company's Fourth Amended and
Restated Revolving Credit Promissory Notes and the Company's three Revolving
Credit Promissory Notes, each dated May 31, 1994, and issued pursuant to the
Existing Credit Agreement, without any discharge, satisfaction or novation of
the underlying indebtedness or any collateral security therefor, all of which
indebtedness and collateral security remain outstanding under this Agreement and
the Note issued pursuant hereto and continue to be secured pursuant to the
Collateral Security Documents.

          (iii) Although the Notes are payable in the full amount of each Bank's
Commitment, the Company shall be obligated to pay only the amounts actually
disbursed to or for the account of the Company, together with interest on the
unpaid balance of sums so disbursed which remains outstanding from time to time,
at the rates and on the dates specified in the Notes and in Sections 1.7 and 1.8
hereof, together with the fees and expenses provided herein. The Company agrees
that, if the Banks, in their sole discretion, agree to extend the Termination
Date or increase the Commitment, the Company will execute and deliver such
amended, restated or revised notes or other instruments and documents, and take
such other action, as the Banks may deem necessary or appropriate in connection
with any such extension of the Termination Date or increase in the Commitment.

<PAGE>

shall be due and payable in full and the Company hereby agrees to make such
payment on such date.

     1.2. Use of Proceeds. The Company represents, warrants and agrees that:
          ---------------

          (a) The proceeds of the Loans made to the Company hereunder have been
or shall be used by the Company solely (i) to finance capital expenditures, (ii)
for general working capital purposes, and (iii) for payment to JII of advances
made by JII to the Company and Management Fees and Home Office Allocations
incurred in the ordinary course of business, to the extent permitted hereunder.

          (b) No part of the proceeds of any Loan made hereunder will be used to
"purchase" or "carry" any "margin stock" or to extend credit to others for the
purpose of "purchasing" or "carrying" any "margin stock" (as such terms are
defined in the Regulation U of the Board of Governors of the Federal Reserve
System), and the assets of the Company do not include, and the Company has no
present intention of acquiring, any such security.

     1.3. Commitment Fee. The Company shall pay to Agent, for distribution
          --------------
by the Agent to the Banks in accordance with their pro rata shares, a commitment
fee computed at the rate of 3/8% per annum on the difference existing from time
to time between (a) the aggregate amount of the Banks' Commitments (as they may
be reduced pursuant to Sections 1.5 and 2A.3), and (b) the outstanding unpaid
principal balance of sums disbursed to the Company by the Banks hereunder. Such
commitment fees shall accrue for the period from the date of this Agreement to
and including the Termination Date, and shall be payable in arrears on the last
day of March, June, September and December of each year, commencing June 30,
1997.

     1.4. Facility Fee. Upon the execution of this Agreement, the Company

their pro rata shares, a facility fee equal to three-eighths of one percent
(3/8%) of the aggregate amount of the Commitments.

     1.5. Termination or Reduction of the Commitment.
          ------------------------------------------

          (a) Voluntary Reductions. The Company shall have the right, upon two
              --------------------
Business Days' prior written notice to Agent, to ratably reduce in part the
Commitments at any time, provided, however, that each partial reduction of the
                         --------  -------
Commitments shall be in a minimum amount of $1,000,000 in the aggregate and in
$100,000 multiples in excess thereof and provided, however, that no reduction
                                         --------  -------
shall reduce the Commitment of any Bank to an amount less than the aggregate
amount of the Loans of such Bank and such Bank's pro rata share of Letters of
Credit outstanding hereunder at the time. The entire Commitments of the Banks
may be terminated in whole at any time upon two Business Days' prior written
notice to Agent.

          (b) Scheduled Reductions. On the last day of each fiscal quarter
              --------------------
during the periods set forth in the left hand column below, the Company shall
reduce each Bank's Commitment by the percentage in the right hand column below
multiplied by such Bank's Commitment as in effect at the opening of business on
September 30, 2000.

                                                   Percentage Reduction
                                                      of each Bank's
                                               September 30, 2000 Commitment
                                               -----------------------------
               Period
               ------

July 1, 2001 through December 31, 2000                      2.5%

January 1, 2001 through December 31, 2001                  3.75%

January 1, 2002 through December 31, 2003                   5.0%

January 1, 2004 through December 31, 2004                  6.25%

January 1, 2005 through June 30, 2005                       7.5%


          (c) Mandatory Reductions. In addition, the Company shall be required
              --------------------
to reduce the Commitments on a pro rata basis (and the foregoing $1,000,000
minimum reduction shall not be applicable thereto), in connection with any sale
of a cable television system owned by the Company from time to time (all such
cable systems which are owned or hereafter acquired by the Company are
hereinafter referred to as the "Cable Systems"), in the amount determined
pursuant to Section 5.6 hereof. If the Company effectuates the third (3rd) sale
of a Cable System after September 30, 2000, and the Company reduces the
Commitments pursuant to this Section 1.5 and Section 5.6 hereof, then the amount
of such a reduction shall be applied against the scheduled reductions under
Section 1.5(b) in inverse order until the entire amount is so applied.

     1.6. Prepayment. Subject to the provisions of Section 1.9 of this
          ----------
Agreement, the Company may prepay the Loans in whole or in part at any time
without premium or penalty; and the prepayments prior to the Termination Date
shall not reduce the Commitments and may be reborrowed. All prepayments shall be
made and applied pro rata against the Notes then outstanding. Prepayments shall
be not less than $1,000,000 in the aggregate and $100,000 multiples in excess
thereof. The Company shall notify the Agent at least one (1) Business Day in
advance of any such prepayments on a Prime Rate Loan and at least two (2)
Business Days in advance of any such prepayments of a Eurodollar Loan. In
addition to the foregoing, the Company shall be required to make a payment (and
the foregoing $1,000,000 minimum reduction shall not be applicable thereto) in
connection with any sale of a Cable System, in the amount determined pursuant to
Section 5.6 hereof.

                                      -5-
<PAGE>

     1.7. Rate of Interest. The Company shall pay interest on the unpaid
          ----------------
principal amount of each Loan from the date of such Loan until the date the
principal balance of such Loan is paid in full at the following rates:

          (a) Prime Rate Loans: During the periods that such Loan is a Prime
              ----------------
Rate Loan, a rate equal to the Base Rate plus the Applicable Margin per annum,
with such interest rate changing when and as the Base Rate changes and when and
as the Applicable Margin changes;

          (b) Eurodollar Loans: During each Interest Period of a Eurodollar
              ----------------
Loan, a rate equal to LIBO Rate for the Interest Period plus the Applicable
Margin per annum, with such rate to change when and as the Applicable Margin
changes;

provided, that, in each case, the unpaid principal balance of a Loan
--------
shall bear interest upon the occurrence and during the continuance of an Event
of Default at a rate equal to two percent (2%) per annum plus the Base Rate,
with such rate changing when and as such Base Rate changes.

     1.8. Interest Periods. If and for so long as any Loan shall be maintained
          ----------------
as a Eurodollar Loan, the period commencing on the date of such Loan and ending
on the date of payment in full shall be divided into "Interest Periods." The
initial Interest Period shall be selected by the Company in the applicable
notice required by section 2.1. The Company may select a subsequent Interest
Period for each Loan by notifying the Agent thereof at least one (1) Business
Day (in the case of a Prime Rate Loan) and two (2) London Business Days (in the
case of a Eurodollar Loan) prior to the first day of the new Interest Period.
Within 5 Business Days after the commencement of each Interest Period, the
Company shall deliver to the Agent written confirmation of the interest rate
applicable to the Eurodollar Loan to which such Interest Period relates and the
term of such Interest Period. If the Company fails to select a subsequent
Interest Period at the termination of an applicable Interest Period for any
Eurodollar Loan in accordance with the preceding sentence, such Loan shall be a
Prime Rate Loan thereafter, until such time that an Interest Period is selected.
The selection of Interest Periods is subject to the following provisions:

          (a) Each Interest Period for a Eurodollar Loan shall be a period of
one (1), two (2), three (3) or six (6) months' duration, or such other periods
requested by the Company which are reasonably available from all the Banks in
their sole discretion in the case of Eurodollar Loans of $1,000,000 or more.

          (b) Interest on each Loan (other than Loans bearing interest at the
rate for Prime Rate Loans) shall accrue from and including the first day of its
Interest Period to, but excluding, the day on which such Interest Period
expires.

          (c) If any Interest Period would otherwise end on a day which is not a
London Business Day, such Interest Period shall be extended to the next
succeeding London

                                      -6-
<PAGE>

Business Day unless such London Business Day falls in another calendar month, in
which case such Interest Period shall end on the next preceding London Business
Day, as applicable (subject to Section 1.8(d) below).

           (d) Any Interest Period for a Eurodollar Loan which begins on the
last London Business Day of a calendar Month (or on a day for which there is no
numerically corresponding day in the calendar month at the end of such Interest
Period) shall end on the last London Business Day of a calendar month.

           (e) No Interest Period for a Loan may extend beyond the Termination
Date.

           (f) No more than eight separate Interest Periods may be in effect at
any one time.

     1.9.  Funding Costs. In connection with any prepayment or repayment of
           -------------
a Eurodollar Loan made on other than the last day of the applicable Interest
Period, whether such prepayment or repayment is voluntary, mandatory, by demand,
acceleration or otherwise, and in connection with any failure by the Company to
fulfill on or before the date specified in a request for an advance of a
Eurodollar Loan the applicable conditions as set forth in this Agreement, the
Company shall pay to Banks all funding costs (other than loss of the Applicable
Margin) which may arise in connection with such prepayment or repayment or
failure to fund, as calculated by Agent in accordance with Exhibit B.
                                                           ---------

     1.10. Other Increased Costs. If, as a result of any (a) change in any
           ---------------------
law or regulation, or in the interpretation thereof by any court or
administrative or governmental authority, (b) charge generally imposed on banks
which are similarly situated to the Banks which affects any Bank in its dealings
in the London Interbank market, (c) violation by the Company of the terms of
this Agreement, or (d) the adoption of or change in any law, rule, regulation or
guideline affecting capital adequacy or compliance by a Bank (or any lending
office of such Bank) or such Bank's holding company with any request or
directive regarding capital adequacy of any court, administrative or
governmental authority, or central bank:

                (i)   the basis of taxation of payments to any Bank of the
          principal of or interest on any Loan or any other amounts payable
          under this Agreement (other than taxes imposed on the overall net
          income of such Bank) is changed;

                (ii)  any reserve (including, without limitation, the
          Certificate Reserve Percentage), special deposit or similar
          requirement relating to any extension of credit or other asset of, or
          any deposits with or other liabilities of any Bank which affects the
          making or maintaining by such Bank of Loans hereunder is imposed,
          modified or deemed applicable;

                                      -7-
<PAGE>

                (iii) any other condition or cost affecting this Agreement or
           the making or maintaining by any Bank of Loans made hereunder is
           imposed on such Bank by law or regulation; or

                (iv)  the rate of return on any Bank's capital or on the capital
           of such Bank's holding company, if any, as a consequence of this
           Agreement, the Commitments or the Loans is or would be reduced

and such Bank reasonably determines that, by reason thereof, the cost to it of
making or maintaining any Loan hereunder is increased, or any amount receivable
by it hereunder in respect to any such Loan is reduced, then the Bank so
affected shall notify the Company thereof within a reasonable time and the
Company shall pay to such Bank, upon written request (which request shall
describe the occurrence and include a calculation of such additional cost or
reduction), such additional amount or amounts as will, in the reasonable
determination of such Bank, compensate such Bank for such additional costs or
reduction; provided, however, that the Company's liability for additional
           --------  -------
amounts computed in accordance with this section shall neither be changed nor
waived by a failure of such Bank to give such notice.

     1.11. Payments. Interest on Prime Rate Loans shall be due and payable
           --------
quarterly on the last day of each March, June, September, and December,
commencing on the first of such days to occur after the date thereof; interest
on Eurodollar Loans shall be due and payable on the expiration date of each
applicable Interest Period and, if the Interest Period is longer than 90 days,
on the last day of each March, June, September and December commencing on the
first of such days to occur after the commencement of such Interest Period. In
addition, interest shall be due and payable on the Termination Date. The Agent
shall give the Company telephonic advice of the amount of each scheduled
principal and interest payment which shall be due on the Notes and shall
thereafter mail a bill to the Company therefor, but failure of the Agent to give
such telephonic advice or to mail any such bill shall not relieve the Company of
its obligations to make timely payments of principal and interest on the Notes.

     1.12. Special Provisions Applicable to Eurodollar Loans.
           -------------------------------------------------

           (a) Change of LIBO Rate. The LIBO Rate may be automatically adjusted
               -------------------
by Agent on a prospective basis to take into account the additional or increased
cost of maintaining any necessary reserves for Eurodollar deposits or increased
costs due to changes in applicable law occurring subsequent to the commencement
of the then applicable Interest Period, including but not limited to changes in
tax laws (except changes of general applicability in corporate income tax laws)
and changes in the reserve requirements imposed by the Board of Governors of the
Federal Reserve System (or any successor) that increase the cost to Banks of
funding any Eurodollar Loan; provided, however, that each Bank shall use
reasonable efforts to minimize such costs, subject, in any event, to such Bank's
sole discretion. Agent shall give the Company notice of such a determination and
adjustment, which determination and adjustment made in good faith shall be prima
facie evidence of the correctness of the fact and the amount of

                                      -8-
<PAGE>

such adjustment. The Company may, by notice to Agent, (A) request Agent to
furnish to the Company a statement setting forth the basis for adjusting such
LIBO Rate and the method for determining the amount of such adjustment; and/or
(B) repay the Eurodollar Loan with respect to which such adjustment is made
pursuant to the requirements of Sections 1.6 and 1.19 hereof.

          (b) Unavailability of Eurodollar Funds. In the event that the Company
              ----------------------------------
shall have requested a Eurodollar Loan in accordance with Section 1.8 hereof and
any Bank shall have reasonably determined that Eurodollar deposits equal to the
principal amount of such Eurodollar Loan and for the Interest Period specified
are unavailable or that the LIBO Rate will not adequately and fairly reflect the
cost of making or maintaining the principal amount of such Eurodollar Loan
during the Interest Period specified or that by reason of circumstances
affecting Eurodollar markets, adequate and reasonable means do not enlist for
ascertaining the LIBO Rate applicable to the specified Interest Period, Agent on
behalf of such Bank shall promptly give notice of such determination to the
Company that the LIBO Rate is not available. A determination by Agent hereunder
made in good faith shall be prima facie evidence of the correctness of such
fact. Upon such a determination, (i) the obligation to advance or maintain
Eurodollar Loans shall be suspended until Agent shall have notified the Company
and Banks that such conditions shall have ceased to exist, and (ii) the Company
shall elect the Prime Rate to be applicable to such Loan in accordance with
Section 1.8 hereof.

     1.13. Taxes. Any and all payments by the Company to the Banks hereunder
           -----
shall be made free and clear of and without deduction for any and all present or
future taxes, levies, imposts, deductions, charges or withholdings, and all
liabilities with respect thereto, excluding in the case of each Bank, (i) taxes
                                  ---------
assessed solely on the income of such Bank, (ii) taxes arising solely from a
connection between such Bank and the jurisdiction imposing such tax, other than
a connection arising from the activities of such Bank solely in connection with
this Agreement, and (iii) United States withholding tax payable with respect to
payments hereunder under laws (including, without limitation, any statute,
treaty, ruling, determination or regulation) in effect on the Initial Date (as
hereinafter defined) for such Bank, provided that any United States withholding
tax payable as a result of any changes in such laws occurring after the Initial
Date shall not be excluded (all such non-excluded taxes, levies, imposts,
deductions, charges, withholding and liabilities being hereinafter referred to
as "Taxes"). For purposes of this Section 1.13, the term "Initial Date" shall
mean, in the case of each Bank, the date of this Agreement and, in the case of
each assignee (for purposes of this Section 1.13, "Assignee"), the date of the
applicable assignment of the Loan. If any Taxes shall be required by law to be
deducted from or in respect of any sum payable hereunder or under any Note to
any Bank or Assignee, (i) the sum payable by the Company shall be increased as
may be necessary so that after making all required deductions (including
deductions applicable to additional sums payable under this Section 1.13) such
Bank or Assignee (as the case may be) receives an amount equal to the sum it
would have received had no such deductions been made, but shall be decreased to
take into account any credit, deduction or offset available in any other
jurisdiction as a result of such payment, and (ii) the Company shall make such
deductions and pay the full amount deducted to the relevant taxation authority
or other authority in accordance with applicable law. The Company shall not,

                                      -9-
<PAGE>

however, be required to pay any amounts pursuant to clause (i) of the preceding
sentence to any Bank organized under the laws of a jurisdiction outside of the
United States, unless such Bank has provided to the Company either (x) a
facially complete Internal Revenue Service Form 4224 or Form 100 1 or other
applicable form, certificate or document prescribed by the United States
Internal Revenue Service certifying as to such Bank's entitlement to an
exemption from, or reduction of, United States withholding tax on payments to be
made hereunder or under the Notes or (y) a letter stating that such Bank is
unable lawfully to provide a properly completed and executed Form 4224 or Form
1001 or (z) other facially complete documents satisfactory to the Agent and the
Company indicating that all payments that will be made to such Bank are exempt
from or subject to a reduced rate of United States withholding tax.

     The Company hereby agrees to pay each Bank the full amount of Taxes
(including, without limitation, any Taxes imposed by any jurisdiction on amounts
payable under this Section 1.13) paid by such Bank decreased to take into
account the effect of any credit, deduction or offset, as determined and
certified by such Bank's tax or accounting department to Company in good faith,
available in any other jurisdiction on account of the payment of Taxes, and any
liability (including penalties, interest, additions to tax and expenses) arising
therefrom or with respect thereto. Each Bank subject to Taxes agrees either, at
its option, to contest the payment of Taxes or to pay or permit the Company to
pay such Taxes when due and payable and, if any such Bank receives a rebate,
refund or other return of Taxes paid by the Company, such Bank will turn over to
the Company the amount rebated, refunded or returned. Payment under this
provision shall be made within thirty (30) days from the date such Bank makes
written demand therefor.

     Within (30) days after the date of any payment of Taxes, the Company will
furnish to the Agent or the applicable Bank the original or a certified copy of
a receipt or other documents reasonably acceptable to the Agent evidencing
payment thereof.

     Any Bank or Assignee organized under the laws of a jurisdiction other than
the United States (or any political subdivision thereof) shall provide from time
to time if requested by the Company and the Agent or required by the Internal
Revenue Service of the United States, (i) a facially complete Internal Revenue
Service Form 4224 (or any successor form) certifying that all payments made to
such Bank are effectively connected with its conduct of trade or business in the
United States and will be includable in its gross income or (ii) a facially
complete Internal Revenue Service Form 1001 (or any successor form) certifying
as to its status for purposes of determining the applicability of a reduced rate
of United States withholding taxes with respect to all payments to be made
hereunder to such Bank pursuant to a double tax treaty obligation of the United
States, or (iii) other facially complete documents satisfactory to the Agent and
Company indicating that all payments that will be made to such Bank are exempt
from or subject to a reduced rate of United States withholding tax. Unless the
Company and Agent have received such forms of such documents validly indicating
that payments hereunder are not subject to United States withholding tax or are
subject to such tax at a rate reduced by an applicable double tax treaty, the
Company or the Agent shall withhold taxes from such payments to such Bank at the
applicable statutory rate.

                                     -10-
<PAGE>

     Notwithstanding any other provision contained herein to the contrary, the
Company and the Agent shall be entitled to deduct and withhold United States
withholding taxes with respect to all payments to be made hereunder to or for
any Bank or Assignee as may be required by United States law due to an
assignment and such Bank or Assignee shall indemnify and hold harmless the
Company and the Agent from and against any tax, interest, penalty or other
expense that the Company and the Agent may incur as a consequence of any failure
to withhold United States taxes applicable because of any assignment that is not
disclosed to them.

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

     2.1. Borrowing Procedure. Loans hereunder shall be made at the principal
          -------------------
banking office of the Agent located in Philadelphia, Pennsylvania (or, in the
case of a successor Agent, the office identified by such successor Agent), upon
telephonic notice from the Company to the Agent specifying (i) the date, which
must be a Business Day, of the proposed borrowing (hereinafter referred to as a
"Funding Date") (ii) the principal amount and type of the proposed Loan and
(iii) in the case of a Eurodollar Loan, the initial Interest Period for such
Loan. Such telephonic notice shall be given to the Agent not later than 2:00
p.m., Agent's local time on the first (1st) Business Day prior to the Funding
Date, in the case of Prime Rate Loans, and not later than 2:00 p.m., Agent's
local time on the second (2nd) Business Day prior to the Funding Date in the
case of Eurodollar Loans. Upon its receipt of such telephonic notice from the
Company, the Agent shall promptly give telephonic notice to each other Bank, and
each such Bank shall have its portion of the Loans available to the Agent in
Agent's principal banking office in immediately available funds on the Funding
Date. Out of the funds received from the Banks for the making of the Loans
hereunder, the Agent will make a Loan to the Company in such amount on behalf of
such Bank. The failure of any of the Banks to lend in accordance with its
Commitment shall not relieve the other Banks of their several obligations
hereunder, but no Bank shall be liable in respect to the obligation of any other
Bank hereunder or be obligated in any event to lend in excess of its Commitment.
Documents delivered to the Agent for the account of each Bank shall be promptly
delivered to such Bank, or in accordance with instructions received from it,
together with copies of such other documents received in connection with the
borrowing as such Bank shall request. Within five (5) Business Days after each
Funding Date, the Company shall deliver to the Agent a written certification,
dated as of the Funding Date in the form of Exhibit C attached hereto confirming
                                            ---------
the matters set forth in clauses (i) through (iii) of this Section 2.1.

     2.2. Computations: Non-Business Days. All interest payable on Eurodollar
          -------------------------------
Loans shall be computed for the actual number of days elapsed using a daily rate
determined by dividing the annual rate by 360, and all interest payable on Prime
Rate Loans and the commitment fees under Section 1.3 hereof and the Letter of
Credit Fees under Section 2A.4(a)(iii) shall be computed on the basis of a year
of 365 or 366 days, as appropriate, for the actual number of days elapsed.
Whenever any payment to be made hereunder or under any Note

                                     -11-
<PAGE>

shall be stated to be due on a Saturday, Sunday or a public holiday under the
laws of the Commonwealth of Pennsylvania, such payment may be made on the next
succeeding Business Day, and such extension of time shall be included in the
computation of interest under the Notes, or commitment fees hereunder, as the
case may be.

     2.3. Application of Payments. All payments and prepayments of principal,
          -----------------------
interest and fees under this Agreement and the Notes shall be made to the Agent
at 1339 Chestnut Street, Philadelphia, Pennsylvania 19101 no later than 2:00
p.m. Philadelphia, Pennsylvania time on the due date thereof in immediately
available funds, for the ratable account of the Banks. The Agent shall promptly
distribute to each such Bank, pro rata, the amount of principal, interest or
fees received by the Agent for the account of such Bank. Any payment to the
Agent for the account of a Bank or a holder of a Note under this Agreement shall
constitute a payment by the Company to such Bank or holder of the amount so paid
to the Agent, and any Notes or portions thereof so paid shall not be considered
outstanding for any purpose after the date of such payment to the Agent.

     2.4. Pro Rata Treatment. All payments or prepayments of principal, interest
          ------------------
or fees shall be made pro rata in accordance with the amounts of the Notes then
outstanding. In the event that any Bank shall receive from the Company or any
other source (other than the sale of a participation to another commercial
lender in the ordinary course of business) any payment of, on account of, or for
any obligation of the Company hereunder or under the Notes (whether pursuant to
the exercise of any right of set off, banker's lien, realization upon any
security held for or appropriated to such obligation, counterclaim or otherwise)
other than as above provided, then such Bank shall immediately purchase, without
recourse and for cash, an interest in the obligations of the same nature held by
the other Bank so that each Bank shall thereafter have a percentage interest in
all of such obligations equal to the percentage interest which such Bank held in
the Notes outstanding immediately before such payment; provided, that if any
payment so received shall be recovered in whole or in part from such purchasing
Bank, the purchase shall be rescinded and the purchase price restored to the
extent of such recovery, but without interest. The Company specifically
acknowledges and consents to the preceding sentence.

     2.5. Deposits: Set Off.  The Company grants each Bank, as security for the
          -----------------
Note of such Bank, a lien and security interest in any and all monies, balances,
accounts and deposits of the Company at such Bank now or at any time hereafter.
If any Event of Default occurs hereunder or any attachment of any balance of the
Company occurs, such Bank may offset and apply any such security toward the
payment of the Note held by such Bank (subject to the requirements of Section
2.4 hereof), whether or not such Note or any part thereof, shall then be due.
Promptly upon its charging any account of the Company pursuant to this section,
the Bank shall give the Company notice thereof.

under, and any unreimbursed draws under, all other Letters of Credit;

           (b) at the time of issuance of a Letter of Credit, the amount

           -----------------------
Commitments as from time to time in effect shall be reduced by the amount

of Credit as permitted pursuant to Section 2A.4(b) hereof.

     2A.3  Approval and Issuance.

                        ---------
hereto. Each Letter of Credit Request Form submitted by the Company to Agent
requesting the issuance of a Letter of Credit shall be certified by the Chief
Executive Officer, Chief Financial Officer, the President, a Vice President or
Treasurer of JII ("Authorized Officer(s)"), and shall, in addition to the
matters described in Section 2.1 hereof, list all Letters of Credit outstanding

     2A.4 Obligations of the Company.
          --------------------------

          (a) The Company agrees to pay to Agent in connection with each Letter
of Credit issued hereunder: (i) immediately upon the demand of Agent on behalf
of all Banks, the amount paid by each Bank with respect to such Letter of
Credit; (ii) immediately upon demand of Agent, the amount of any draft presented
purporting to be drawn under such Letter of Credit provided that the draft and
accompanying documents conform to the terms of the Letter of Credit but subject
to the terms of Section 2A.7 (whether or not Agent has at such time honored such
draft) and any other amounts paid thereunder (it being understood that Agent is
not required to make demand upon or proceed against any Bank or other party or
to resort to any Collateral before obtaining payment from Company); (iii) on the
date of issuance of each Letter of Credit and on the effective date of any
extension or renewal of any Letter of Credit a non-refundable fee for the
benefit of Banks in accordance with each Bank's pro rata share of the face
amount of such Letter of Credit equal to the Applicable Margin in effect for the
LIBO Rate interest option on such date; (iv) interest on any indebtedness
outstanding with respect to such Letter of Credit, whether for funds paid on
drafts on such Letter of Credit, or otherwise (but such indebtedness shall not
include undrawn balances of such Letter of Credit issued hereunder) at the rate
applicable to Prime Rate Loans under Section 1.7(a) hereof from the date of
payment by Agent (if not reimbursed by the Company on the same day) to the date
one (1) Business Day after notice to the Company of such payment, and thereafter
at the rate of 2% per annum plus the Base Rate. Interest under the preceding
clause (iv) shall be paid at the times and in the manner set forth in Section
1.7(a) hereof, and shall accrue on amounts paid on a Letter of Credit (if not
reimbursed by the Company on the same day) from the date of payment by Agent,
whether or not demand is made, until such amounts are reimbursed by the Company
whether before, at or after demand.

          (b) On or before the Termination Date, in the absence of a Default or
Event of Default, and subject to the provisions of Section 2.1 hereof, Banks
hereby agree to advance

                                      -14-
<PAGE>

funds to the Company under the Commitment to make the payments required under
Sections 2A.4(a)(i) and (ii) hereof. If any payment by the Agent of a draft
drawn under a Letter of Credit is for any reason (including without limitation
the occurrence or continuation of a Default or Event of Default hereunder) not
reimbursed prior to or on the date of such payment, the amount of such payment
shall thereupon be deemed for purposes hereof a Loan under Section 2.1 hereof
but payable upon the demand of Agent at the direction of Required Banks. Such
demand reimbursement obligation shall be otherwise subject to all the terms and
conditions thereof as if loaned by Banks pursuant to Section 2.1 hereof (but
without duplication).

     2A.5 Payment by Banks on Letters of Credit.
          -------------------------------------

          (a) With respect to each Letter of Credit, each Bank agrees that it is
irrevocably obligated to pay to Agent, for each such Letter of Credit, such
Bank's Pro Rata Share of each and every payment made or to be made by Agent
under such Letter of Credit (each such payment to be made, a "LOC
Contribution"). Each Bank's LOC Contribution shall be due from such Bank
immediately upon, and in any event no later than the same day as, receipt of
written notice (which may be sent by telex or telecopier) from Agent (except
that if such notice is received after 3:00 p.m. on any Business Day, payment may
be made on the following Business Day, together with interest equal to the
effective rate for overnight funds in New York as reported by the Federal
Reserve Lender of New York for such day (or, if such day is not a Business Day,
for the next preceding Business Day)) that (i) it has made a payment or (ii) a
draft has been presented purporting to be drawn on a Letter of Credit issued
hereunder. Such payment shall be made at Agent's offices in immediately
available federal funds.

          (b) The obligation of each Bank to make its LOC Contribution hereunder
is absolute, continuing and unconditional, and Agent shall not be required first
to make demand upon or proceed against the Company or any guarantor or surety,
or any others liable with respect to the applicable Letter of Credit and shall
not be required first to resort to any Collateral. LOC Contributions shall be
made without regard to termination of this Agreement or the Commitment, the
existence of an Event of Default or Default hereunder, the acceleration of
indebtedness hereunder or any other event or circumstance.

     2A.6 Collateral Security.
          -------------------

          (a) The indebtedness, liabilities and obligations of the Company under
this Section 2A, however created or incurred, whether now existing or hereafter
arising, due or to become due, absolute or contingent, direct or indirect,
secured or unsecured, are among the obligations secured by the security
interests, liens and encumbrances created by the Collateral Security Documents
delivered to Agent, and Agent and the Banks are entitled to the benefit of the
collateral security granted thereunder with respect to such indebtedness.

          (b) Notwithstanding the payment in full of all the Loans made under
the Commitment, the termination of the Commitment or the occurrence of the
Termination Date, the

                                     -15-
<PAGE>

Collateral shall continue to secure the indebtedness, liabilities and
obligations of the Company under this Section 2A until all Letters of Credit
shall have expired and all indebtedness, liabilities and obligations under this
Section 2A shall have been paid in full.

          (c) On the Termination Date and the occurrence of an Event of Default,
Required Banks may require (and in the case of an Event of Default occurring
under Section 7.7 it shall be required automatically) that the Company deliver
to Agent, cash or U.S. Treasury Bills with maturities of not more than 90 days
from the date of delivery (discounted in accordance with customary banking
practice to present value to determine amount) in an amount equal at all times
to one hundred ten percent (110%) of the outstanding undrawn amount of all
Letters of Credit, such cash or U.S. Treasury Bills and all interest earned
thereon to constitute cash collateral for all such Letters of Credit. At such
time as such collateral is required to be and has not been deposited, Agent on
behalf of Banks shall be entitled to liquidate such of the other collateral for
the Loan (if any) as is necessary or appropriate in its sole judgment so as to
create such cash collateral.

          (d) Any cash collateral deposited under subparagraph (c) above, and
all interest earned thereon, shall be held by Agent and invested and reinvested
at the expense and the written direction of the Company, in U.S. Treasury Bills
with maturities of no more than ninety (90) days from the date of investment.

     2A.7 General Terms of Credits. The following terms and conditions
          ------------------------
apply with respect to each Letter of Credit (a "Credit") notwithstanding
anything to the contrary contained herein:

          (a) the Company assumes all risks of the acts or omissions of the
beneficiary of each Credit with respect to the use of the Credit or with respect
to the beneficiary's obligations to the Company. None of the Banks nor any of
their officers or directors shall be liable or responsible for, and the Banks
hereby agree to ratably indemnify and hold Agent and any issuer of a Credit
harmless (except for the issuer's gross negligence or willful misconduct) with
respect to: (i) the use which may be made of the Credit or for any acts or
omissions of the beneficiary in connection therewith; (ii) the accuracy, truth,
validity, sufficiency or genuineness of documents, or of any endorsement
thereon, even if such documents should in fact prove to be in any or all
respects false, misleading, inaccurate, invalid, insufficient, fraudulent, or
forged; (iii) the payment by Agent against presentation of documents which do
not comply with the terms of the Credit, including failure of any documents to
bear any reference or adequate reference to a Credit; (iv) any other
circumstances whatsoever in making or failing to make payment under a Credit; or
(v) any inaccuracy, interruption, error or delay in transmission or delivery of
correspondence or documents by post, telegraph or otherwise. In furtherance and
not in limitation of the foregoing, Agent may accept documents that appear on
their face to be in order, without responsibility for further investigation,
regardless of any notice or information to the contrary.

          (b) Notwithstanding the foregoing, with respect to any Credit, the
Company shall have a claim against Agent, and Agent shall be liable to the
Company, to the extent,

                                     -16-
<PAGE>

but only to the extent, of any direct, as opposed to indirect or consequential,
damages suffered by the Company caused by the Agent's willful misconduct or
gross negligence.

          (c) To the extent not inconsistent with this Agreement, the Uniform
Customs and Practices for Documentary Credits (1993 Revision), International
Chamber of Commerce Publication No. 500, are hereby made a part of this
Agreement with respect to obligations in connection with each Credit.

                                  THE AGENT
                                  ---------

     This Article sets forth the relative rights and duties of Agent and Banks
respecting the Loans and does not confer any enforceable rights on the Company
against Banks or create on the part of Banks any duties or obligations to the
Company.

     8.1. Appointment and Powers. Each of the Banks hereby appoints CoreStates
          ----------------------
as Agent for the Banks hereunder, and authorizes the Agent to take such action
as Agent on its behalf and to exercise such powers as are specifically delegated
to the Agent by the terms hereof, together with such powers as are reasonably
incidental thereto. The duties of the Agent shall be entirely ministerial; the
Agent shall not have any duty to ascertain or to inquire as to the performance
or observance of any of the terms, covenants or conditions of this Agreement,
the Notes or any related document, or to enforce such performance, or to inspect
the property (including the books and records) of the Company; and the Agent
shall not be required to take any action which exposes the Agent to personal
liability or which is contrary to this Agreement or the Notes or applicable law.
CoreStates agrees to act as Agent upon the express terms and conditions
contained in this Article VIII.

     8.2. Application of Payments.  Agent shall apply all payments of principal,
          ------------------------
interest, commitment fee, facility fee, letter of credit fee, or other amounts
hereunder made to Agent by or on behalf of the Company, to Banks on the basis of
their pro rata shares of the outstanding principal balance of indebtedness
hereunder, except any Agent's fee paid in connection herewith which shall be
paid solely to Agent. Such distribution of payments shall be made promptly in
federal funds immediately available at the office of each Bank set forth above.

     8.3. Modifications and Waivers. No modification or amendment hereof,
          -------------------------
consent hereunder or waiver of Event of Default shall be effective except by
written consent of the Required Banks, provided, however, that the written
consent of all Banks shall be required to modify, amend, waive, discharge,

(i) the rate of interest, to the extent it is proposed to be decreased, (ii) the
amount of the Commitments, and of each Bank's respective Commitment, (iii) the
dates of payment hereunder, (iv)

provided to the Agent on behalf of Banks pursuant to the Collateral Documents
(other than in connection with a sale of a Cable System which is permitted
hereunder) if the Collateral to be released is valued (based on the Company's
good faith estimate) at Fifty Thousand Dollars ($50,000) or more, and (vi) the
provisions of this Section 8.3 or the definition of Required Banks. The Banks
hereby agree to execute such further documents including without limitation
amendments to this Agreement and the Note(s), waivers and certificates and
deliver such opinions as the Agent and its counsel shall so request to implement
any modifications approved in accordance with the terms of this Section 8.3. Any
amendment or waiver made pursuant to this Section 8.3 shall apply to and bind
all of the Banks and any future holder of any Notes. No modification or waiver
of any provision of this Agreement or any Note, nor any consent to any departure
by the Company here from or therefrom, shall in any case be effective unless the
same be in writing, and then such waiver or consent shall be effective only in
the specific instance and for the specific purpose for which given. No notice to
or demand on Company in any case shall entitle Company to any other or further
notice or demand in any similar or other circumstances.

     8.4. Obligations Several. The obligations of the Banks hereunder are
          -------------------
several, and each Bank hereunder shall not be responsible for the obligations of
the other Banks hereunder, nor, will the failure of one Bank to perform any of
its obligations hereunder relieve the other Banks from the performance of their
respective obligations hereunder.

     8.5. Responsibility. The Agent (i) makes no representation or warranty
          --------------
to any Bank and shall not be responsible to any Bank for any oral or written
recitals, reports, statements, warranties or representations made in or in
connection with this Agreement or any Note; (ii) shall not be responsible for
the due execution, legality, validity, enforceability, genuineness, sufficiency,
collectibility or value of this Agreement or any Note or any other instrument or
document furnished pursuant thereto; (iii) may treat the payee of any Note as
the owner thereof until the Agent receives written notice of the assignment or
transfer thereof signed by such payee and in form satisfactory to the Agent;
(iv) may execute any of its duties under this Agreement by or through employees,
agents and attorneys in fact and shall not be answerable for the default or
misconduct of any such employee, agent or attorney in fact selected by it with
reasonable care; (v) may (but shall not be required to) consult with legal
counsel (including counsel for the Company), independent public accountants and
other experts selected by it and shall not be liable for any action taken or
omitted to be taken in good faith by it in accordance with advice of such
counsel, accountants or experts; (vi) shall be entitled to rely upon any Note,
notice, consent, waiver, amendment, certificate, affidavit, letter, telegram,
telex, cable or other document or communication believed by it to be genuine and
signed or sent by the proper party or parties, and may rely on statements
contained therein without further inquiry or investigation. Neither the Agent
nor any of its directors, officers, agents, or employees shall be liable for any
action taken or omitted to be taken by it or them under or in connection with
this Agreement on the Notes, except for its or their own gross negligence or
willful misconduct.

     8.6. Agent's Indemnification. The Banks agree to indemnify and reimburse
          -----------------------
the Agent (to the extent not reimbursed by the Company), ratably from and
against any and all liabilities,

<PAGE>

obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind or nature whatsoever which may be imposed
on, incurred by, or asserted against the Agent as such in any way relating to or
arising out of this Agreement or any action taken or omitted by the Agent under
this Agreement, provided that no Bank shall be liable for any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements resulting from the Agent's gross negligence or
willful misconduct. Without limitation of the foregoing, each Bank agrees to
reimburse the Agent promptly upon demand for its ratable share of any out-of-
pocket expenses (including counsel fees) incurred by the Agent in connection
with the preparation, execution, administration or enforcement of, or the
preservation of any rights under, this Agreement to the extent that the Agent is
not reimbursed for such expenses by the Company.

     8.7. Action on Instruction of Banks; Right to Indemnity. Agent shall in all
          --------------------------------------------------
cases be fully protected in acting or refraining from acting hereunder in
accordance with written instructions to it signed by Required Banks unless the
consent of all the Banks is expressly required hereunder in which case Agent
shall be so protected when acting in accordance with such instructions from all
the Banks. Such instructions and any action taken or failure to act pursuant
thereto shall be binding on all the Banks, provided that except as otherwise
provided herein, Agent may act hereunder in its own discretion without
requesting such instructions. Agent shall be fully justified in failing or
refusing to take any action hereunder unless it shall first be specifically
indemnified to its satisfaction by the other Banks on a pro rata basis against
any and all liability and expense which it may incur by reason of taking or
continuing to take any such action.

     8.8. Rights as a Lender. With respect to its Commitment and the Note
          ------------------
issued to it, CoreStates, in its individual capacity as a Bank, shall have, and
may exercise, the same rights and powers under this Agreement and the Note
payable to it as the other Bank has under this Agreement and Note, and the terms
"Bank" and "Banks", unless the context otherwise requires, shall include
CoreStates in its individual capacity as a Bank. CoreStates and its affiliates
may accept deposits from, lend money to, act as trustee under indentures of, and
generally engage in any kind of banking or trust business with, the Company, any
Affiliate of the Company, or any of its subsidiaries and any person, firm or
corporation who may do business with or own securities of the Company, such
Affiliate or any subsidiary, all as if it were not the Agent, and without any
duty to account therefor to the Banks; provided, however, that Agent hereby
agrees that if it agrees to make any loan to the Company (but not any Affiliate
of the Company, or any subsidiary or any person, firm or corporation which may
do business with or own securities of the Company), and the Company provides a
security interest in its assets covered by the Collateral Documents, that any
such security interest shall be junior to the security interests granted to
Agent on behalf of Banks under the Collateral Documents.

     8.9. Credit Investigation. Each of the Banks severally represents and
          --------------------
warrants to the other Bank and to the Agent that it has made its own independent
investigation and evaluation of the financial condition and affairs of the
Company in connection with such Bank's execution and delivery of this Agreement
and the making of its loans and has not relied on any information or

                                     -35-
<PAGE>

evaluation provided by any other Bank or the Agent in connection with any of the
foregoing (other than information provided by the Company to the Agent for
transmittal to the Banks in connection with the foregoing); and each Bank
represents and warrants to the other Bank and to the Agent that it shall
continue to make its own independent investigation and evaluation of the
creditworthiness of the Company while the Commitments and/or the Notes are
outstanding.

     8.10. Resignation, Removal of Agent.
           -----------------------------

           (a) Agent may at any time resign its position as Agent, without
affecting its position as a Bank, by giving written notice to Banks and the
Company. Such resignation shall take effect upon the appointment of a successor
agent in accordance with this Article. In the event Agent shall resign, the
Company shall appoint a successor agent, subject to the consent of the Required
Banks, which shall not be unreasonably withheld. If within thirty (30) days of
the Agent's notice of resignation no successor agent shall have been appointed
by the Company and accepted such appointment, then Agent, in its discretion may
appoint any other Bank as a successor agent, subject to such Bank's acceptance
of such appointment and to approval by the Company, which approval will not be
unreasonably withheld.

           (b) All Banks other than the Agent may remove the Agent, without
affecting its position as a Bank, by giving written notice signed by all such
Banks to the Agent. Such removal shall take effect thirty (30) business days
following Agent's receipt of notice of removal. The removal notice shall
identify the successor Agent (which shall be a Bank, or shall have been approved
by Company).

     8.11. Successor Agent. The successor Agent appointed pursuant to Section
           ---------------
8.10 shall execute and deliver to its predecessor and Banks an instrument in
writing accepting such appointment, and thereupon such successor, without any
further act, deed or conveyance, shall become fully vested with all the
properties, rights, duties and obligations of its predecessor Agent. The
predecessor Agent shall deliver to its successor Agent forthwith all collateral
security, documents and moneys held by it as Agent, if any, whereupon such
predecessor Agent shall be discharged from its duties and obligations as Agent
under this Agreement.

     8.12. Collateral Security. Agent will hold, administer and manage any
           -------------------
collateral security pledged from time to time hereunder either in its own name
or as Agent, but each Bank shall hold a direct, undivided beneficial interest
therein, by reason of and as evidenced by this Agreement.

     8.13. Enforcement by Agent. All rights of action under this Agreement
           --------------------
and under the Notes and all rights to the collateral security, if any, hereunder
may be enforced by Agent and any suit or proceeding instituted by Agent in
furtherance of such enforcement shall be brought in its name as Agent without
the necessity of joining as plaintiffs or defendants any other Banks, and the
recovery of any judgment shall be for the benefit of Banks subject to the
expenses of Agent.
