[LOGO OF CSG SYSTEMS, INC. APPEARS HERE] 


April 3, 1998



Mr. Mark Halpin
Executive Vice President and CFO
Renaissance Media
Cablevision Center
Suite 100
Ferndale, NY 12734

Dear Mark:

       I am enclosing a copy of the executed agreement between our companies. 
There is an issue with the contracts you sent. One had a change for adding your 
corporate office telecommunications line at no charge; the other didn't. The one
which is executed is the one which did not have the change.

       As you will recall, we agreed to add all system sites' primary locations
to receive the telecom line at no charge - including Jackson, TN (which
currently pays for their line): this did not include your corporate office. In
fact, Todd Fielding of CSG provided Darlene Fedun with pricing for a separate
phone line and installation charges. It was then decided for you to use the TW
Liberty division communications line - with Renaissance paying only a minimal
amount to separate the ports off the existing controller and for you to work out
a deal with Liberty division regarding the phone line. I'm not even privy to the
deal you worked out with them!

       I've also enclosed a clean copy of the contract for you to sign again 
and send back to me, should you want a
 fully executed original copy.

       Mark, this is a good deal for both our companies and I appreciate working
with you and the people in Liberty again. Should you have any questions, please 
call me.

Sincerely,



David Wyllie
National Sales Manager

performance as was intended to be provided by the Product which it replaces. Any
such corrected or replaced Product shall be warranted for the remainder of the 
Warranty Period or for thirty (30) days, whichever is longer. Customer

copyright, trademark secret or other proprietary right owned by a third person,

rata share of any maintenance fees that Customer actually paid to CSG for the
period that such Product was not usable.

(c)  Limitation. CSG shall have no indemnity obligation to Customer under this

          substantially all of its creditors, or enters in to an agreement for

          notice thereof to such party, terminate this Master Agreement as of
          the date specified in such notice of termination.

     (d)  If Customer or any of Customer's employees or consultants breach any
          term or condition of any Schedule attached hereto for the license of
          software or products distributed by or through CSG, including the
          Incorporated Third Party Software, CSG may, at CSG's option, terminate

maintaining and supporting the CCS Products. CSG shall certify the Designated
Environment prior to the commencement of CSG's obligations under this Schedule
                                                                      --------

Schedule C will not require CSG to (i) develop and release Updates or
- ----------
Enhancements (ii) customize the Updates or Enhancements to satisfy Customer's
particular requests or (iii) obtain Updates or Enhancements to any third party
product. If an Update or Enhancement replaces the prior version of the CCS
Product, Customer will destroy such prior version and all archival copies upon
installing the Update or Enhancement.

6. Term. This Schedule C shall be effective from the Effective Date as defined
              ---------- 
in the Master Agreement and, unless terminated pursuant to Section 16 of the
Master Agreement, will remain in effect for a period of six (6) years (the

TCP/IP connectivity to CSG's Millennium Data Center in Englewood, CO via one of 
the following methods:
      1.   Leased IP/multi-protocol connection with minimum 56Kb. (for example, 
           Advantis)
      2.   Leased Internet connection with minimum 56Kb.
      3.   Dial-up connection through Internet Service Provider.

      The Vantage workstation must be on the IP network.

(Consideration must be given to the overall environment in which Vantage will 
run. IP does not provide load balancing or prioritization on the line. 
Therefore, if a multi-protocol circuit is used for both Vantage and CCS/ACSR, 
consideration must be given to the estimated amount of activity generated from 
Vantage. The type activity generated from Vantage is decision support and can 
therefore fluctuate.)

Using Vantage in the ACSR and/or ACSR Telephony Product environment
- -------------------------------------------------------------------

The ACSR product runs on an IP LAN with a SUN Server. ACSR and Vantage can run 
concurrently on the same workstation. However, consideration must be given to 
the overall workstation configuration during installation if this is desired.

Additionally, CSG's CIT product also uses Forest & Trees for reporting purposes.
CIT reporting can be functional on the Vantage workstation. However, 
consideration must be given to each product's configuration.

CSG should be consulted for specific installation and configuration information.

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

1.   A modem is only required for dial-up connectivity through the Internet.

2.   If the Vantage PC will be used in the ACSR environment, the ACSR PC 
     Workstation Requirements should be used for both Vantage and ACSR, with the
     inclusion of the additional Vantage software. Vantage will only operate on 
     a PC workstation.

Contact CSG for more information.

                 -------------------------------------------
                     PRIORITY LEVELS - (excluding Vantage)
                     -------------------------------------
         (Note: for Vantage support detail - see page 2 of Exhibit C-3)
         --------------------------------------------------------------

When contacting the PRODUCT SUPPORT CENTER, the caller should be prepared to
provide detailed information regarding the problem and the impact on the
operation and the end user. Each problem or question is assigned a tracking
number and a priority. The priority is set to correspond with the urgency of the
problem. It is very important that the customer describe the urgency of the
problem when it is reported. The priority levels are described below:

 .    CRITICAL (PRIORITY 1): Complete loss of functionality, system outage or
     down production system. Customers cannot access the system, cannot perform
     any function due to the hardware being down, are experiencing network
     control or communication problems, or are unable to process. The customer
     will receive immediate response and prioritized at the highest level. Once
     control has been regained, efforts are then made to determine the "root
     cause" of the problem. Considering the nature of the cause, the problem is
     adjusted to one of the other priorities and processed accordingly. While a
     Critical (Priority 1) problem exists, the Product Support Center commitment
     is to provide around-the-clock support until customers
     system/network/application is restored to operational status.

 .    SERIOUS (PRIORITY 2): Partial loss of functionality, or loss of critical
     functionality. The Customer's production/processing system is not down but
     there is an impact within the system/network. The Customer will receive
     immediate response. If the problem persists, the control of the network may
     be lost and/or end-user impacts may become serious. The Customer will
     receive immediate response. The Product Support Center's goal

                            EXHIBIT C-3 (Page 2 of 3)

     is to ensure that control of the system is not jeopardized and to work with
     Customer to gather information in order to resolve the issue. The Product
     Support Center allocates resources during normal business hours until a
     permanent solution is found.

 .    OPERATIONAL (PRIORITY 3): Partial loss of functionality loss of
     non-critical functionality, or loss of critical functionality for which a
     work around exists. The problem is within the customers' operations
     environment. The user is attempting to utilize a CSG product and is having
     difficulty completing the process. A user may be a CSR, subscriber, or the
     Customer's operation staff running the system. CSG's Product Support Center
     goal is to respond the next business day.

 .    INCONVENIENCE OR ENHANCEMENT (PRIORITY 4): Inconvenience or loss of
     functionality for which a work-around solution exists, or enhancement
     request is required. The problem is an operator inconvenience, an
     enhancement, or the Customer have requested information. There is no
     serious impact to the end user of the system. The problem can be avoided by
     proper operator action, internal training by the customer, or a work-around
     solution. There is no apparent danger of losing control of the system,
     network, application or data because of this type of problem. A suggestion
     or request for enhancement is based upon the problem, concern or business
     need. The Product Support Center's goal is to provide a correction through
     internal software control procedures. CSG's Product Support Center goal is
     to respond within (3) business days.

 .    INFORMATIONAL (PRIORITY 5): This category also includes questions. The
     Product Support Center is committed to responding with the requested
     information within (5) business days. Software correction notification may
     be sent to the customer shortly after the correction has been made by our
     development engineers. At times, a work-around may be suggested if: 

         . Its delivery is more timely 
         . Its implementation is less complex 
         . Its reliability is more certain

     However, a work around must be mutually acceptable to our Customers, and it
     must have the effect of reducing the concern until a permanent resolution
     can be determined. Should the Customer wish to check the status of a
     problem they may contact the Product Support Center desk representatives or
     their Account Manager. In either case, the customer should reference the
     tracking number.

Customer may request to have the priority of Customer's call upgraded. Customer
may check on the status of such request at any time by calling the Product
Support Center or contacting Customer's account manager. The account manager is
responsible for problem escalation to the appropriate level of management if
Customer is not satisfied with a response.

    --------------------------------------------
development and programming services related to design and use of the ESP
Statements (the "Work") and create the work product deliverables (the "Work
Product") set forth in a separately executed and mutually agreed upon ESP Work
Order (the "Work Order") by the completion date set forth on the Work Order. The
ESP Statement will contain the Customer and CSG Intellectual Property set forth
on the Work Order. Customer shall pay CSG the Development Fee for the Work and
the Work Product set forth on the Work Order upon acceptance of the ESP
Statements in accordance with the Work Order. Except with respect to Customer's
Intellectual Property, Customer agrees that the Work and Work Product shall be
the sole and exclusive property of CSG. Customer shall have no proprietary
interest in the Work Product or in CSG's billing and management information
software and technology and agrees that the Work Product is not a work specially
ordered and commissioned for use as a contribution to a collective work and is
not a work made for hire pursuant to United States copyright law. After CSG has
completed the Work and the Work Product, CSG will produce ESP Statements for
Customer.

(b) Supplies. CSG will suggest and Customer will select the type and quality of
    --------
the paper stock, carrier envelopes and remittance envelopes for the ESP
Statements (the "Supplies"). CSG shall purchase Customer's requirements of
Supplies necessary for production and mailing of the ESP Statements. CSG shall
charge Customer the rates set forth in Schedule F for purchase of Supplies.
                                       ----------
(c) Right of Customer's Intellectual Property. Customer provides to CSG a
    -----------------------------------------
non-exclusive right to use all of Customer's Intellectual Property necessary to
design, produce and mail the ESP Statements directly or indirectly. CSG shall
have the right by notice to Customer to cease use of any of Customer's
Intellectual Property on ESP Statements at any time. Customer represents and
warrants that it owns or has licensed all Customer's Intellectual Property and
has full power and authority to grant CSG the license set forth herein and that
CSG's use of Customer's Intellectual Property on the ESP Statements will not
constitute a misuse or infringement of the Customer's Intellectual Property or
an infringement of the rights of any third party. Customer will use best efforts
to maintain its rights to use and license Customer's Intellectual Property and
will immediately advise CSG of the loss of Customer's right to use any
Customer's Intellectual Property and will advise CSG of all copyright and other
notices that must be used in connection with Customer's Intellectual Property
and of any restrictions on use of Customer's Intellectual Property relevant to
CSG's activities hereunder.

(d) Indemnification Relating to ESP Statements. Customer shall indemnify, defend
    ------------------------------------------
and hold CSG harmless from any claims, demands, liabilities, losses, damages,
judgments or settlements, including all reasonable costs and expenses related
thereto (including attorneys' fees), directly or indirectly resulting from
Customer's breach of any representation or warranty under this Section 5, and
the Work Product, except for those arising out of CSG Intellectual Property.

6. Per Cycle Minimum. As of the Commencement Date as defined in Section 9 below,
for each month that this Agreement is in effect, Customer will maintain per each
billing cycle a minimum of five hundred fifty (550) subscribers on the CSG
System. Per System Site, Customer will have a minimum of four (4) cycles per
month but no more than twenty-eight (28) cycles per month.

7. Discontinuance Fees. During the term of this Schedule G, each month Customer
                                                ----------
shall be responsible for paying CSG the actual Print and Mail Services fees
incurred during such month. The parties have mutually agreed upon the fees for
the Print and Mail Services to be provided hereunder based upon certain assumed
volumes of processing activity, and the length of the term of Schedule G.
                                                              ----------
Customer acknowledges and agrees that, without the certainty of revenue promised
by the commitments set forth in this Schedule G, CSG would have been unwilling
                                     ----------
to provide the Print and Mail Services at the fees set forth in the Schedule F.
                                                                    ----------
Because of the difficulty in ascertaining CSG's actual damages for a termination
or other breach of this Agreement (including, but not limited to, Schedule G) by
                                                                  ----------
Customer before the expiration of the then-current term with respect to one or
more System Site, Customer agrees that, in addition to all other amounts then
due and owing to CSG, Customer will pay to CSG (as a contract discontinuance fee
and not as a penalty) an amount equal to fifty percent (50%) of Customer's
average monthly invoice for Print and Mail Services during the three (3) months
prior to any such termination or other breach by Customer, multiplied by the
number of months remaining in the term of this Schedule G, had there been no
                                               ----------
breach or termination ("Discontinuance Fee"). Customer acknowledges and agrees
that the Discontinuance Fee is a reasonable estimation of the actual damages
which CSG would suffer if CSG were to fail to receive the amount of processing
business contemplated by this Schedule G. Customer shall not be required to pay
                              ----------
the Discontinuance Fee if CSG terminates this Schedule G other than as a result
                                              ----------
of Customer's breach of its obligations hereunder or if Customer terminates the
Schedule G for a material, uncured breach by CSG.
- ----------

8. Deposit. At least seven (7) days prior to the Commencement Date of the Print
and Mail Services set forth in Section 9 below, Customer shall pay CSG a
security deposit (the "Deposit") for the payment of the expenses described in
Sections 2 and 3 of this Schedule G (the "Disbursements"). The Deposit will
                         ----------
equal the estimated amounts of Disbursements for one (1) month as determined by
CSG based upon the project volume of applicable services to be performed monthly
by CSG. If Customer incurs Disbursements greater than the Deposit for any month,
Customer shall, within thirty (30) days of receipt of a request from CSG to
increase the Deposit, pay CSG the additional amount to be added to the Deposit.
If Customer fails to pay the additional amount requested within such 30-day
period, CSG may terminate this Master Agreement as provided for in Section 16.
Upon written request from Customer, CSG will return to Customer a portion of the
Deposit if the Disbursements incurred by Customer on a monthly basis are less
than the Deposit for three (3) consecutive months. In addition to the foregoing,
CSG shall have the right to apply the Deposit to the payment of any invoice from
CSG which remains unpaid during the term of this Agreement, and Customer agrees
to replenish any such Deposit amount as set forth above. Any portion of the
Deposit that remains after the payment of all amounts due to CSG following the
termination or

<PAGE>
 
expiration of this Master Agreement will be returned to Customer. Customer shall
not be entitled to receive interest on the Deposit while it is maintained by
CSG.

9. Term. The first day of the calendar month in which the Print and Mail
Services commence shall be referred to as the Commencement Date." Unless
terminated pursuant to Section 16 of the Master Agreement, the Print and Mail
Services shall continue for a period of six (6) years from the Commencement Date
(the "Initial Term") and shall automatically be extended for additional one-year
terms (the "Additional Terms") unless either party gives the other party at
least six (6) months prior written notice of such party's intent not to extend.

refund to Customer the amount actually paid to CSG for such item of Incorporated
Third Party Software, less amortization based on a 5-year straight-line
amortization schedule.

c. Limitation. CSG shall have no indemnity obligation to Customer under this
