  THIS MATERIAL IS BEING FORWARDED TO YOU AS THE BENEFICIAL OWNER OF SHARES OF
VIACOM COMMON STOCK HELD BY US FOR YOUR ACCOUNT BUT NOT REGISTERED IN YOUR
NAME. A TENDER OF SUCH SHARES OF VIACOM COMMON STOCK MAY ONLY BE MADE BY US AS
THE HOLDER OF RECORD AND PURSUANT TO YOUR INSTRUCTIONS. THE LETTER OF
TRANSMITTAL IS FURNISHED TO YOU FOR YOUR INFORMATION ONLY AND CANNOT BE USED
BY YOU TO TENDER SHARES OF VIACOM COMMON STOCK HELD BY US FOR YOUR ACCOUNT.
 
  Accordingly, we request instructions as to whether you wish us to tender any
or all such shares of Viacom Common Stock held by us for your account,
pursuant to the terms and conditions set forth in the Exchange Offer.
 
  Your attention is invited to the following:
 
    1. The Exchange Ratio Range within which you may tender for exchange is
  not greater than [.  ] nor less than [.  ] a share of VII Cable Class A
  Common Stock for each share of Viacom Common Stock tendered and exchanged.
 
    2. Viacom currently holds all of the shares of VII Cable Class A Common
  Stock, all of which will be distributed pursuant to the Exchange Offer. As
  more fully described in the Offering Circular - Prospectus, upon the
  occurrence of certain events immediately following the consummation of the
  Exchange Offer, the shares of VII Cable Class A Common Stock will
  automatically convert into shares of VII Cable Preferred Stock.

 
     
    3. The Exchange Offer, proration period and withdrawal rights will expire
  at 12:00 Midnight, New York City time, on July 22, 1996, unless extended.
      
    4. A holder of Viacom Common Stock has the right to tender all, or a
  portion, of such holder's shares of Viacom Common Stock.
 
    5. Holders of Viacom Common Stock will receive that fraction of a share
  of VII Cable Class A Common Stock designated by such holders, or such
  greater fraction as may be represented by the Final Exchange Ratio, for
  each share of Viacom Common Stock accepted for exchange.
 
    6. HOLDERS OF SHARES OF VIACOM COMMON STOCK ELECTING TO TENDER SUCH
  SHARES IN THE EXCHANGE OFFER SHOULD NOT EXPECT TO TAKE PHYSICAL DELIVERY OF
  SHARES OF VII CABLE CLASS A COMMON STOCK WHICH THEY WILL HAVE THE RIGHT TO
  RECEIVE IN EXCHANGE FOR SHARES OF VIACOM COMMON STOCK AFTER THE
  CONSUMMATION OF THE STOCK ISSUANCE (AS DEFINED IN THE OFFERING CIRCULAR -
   PROSPECTUS).
 
    7. Tendering stockholders will not be obligated to pay brokerage fees or
  commissions or, except as otherwise provided in Instruction 7 of the Letter
  of Transmittal, stock transfer taxes with respect to the exchange of shares
  in the Exchange Offer.
 
    8. Please instruct us clearly if you wish to tender some shares of Viacom
  Common Stock at one Exchange Ratio and other shares of Viacom Common Stock
  at another Exchange Ratio. We must submit separate Letters of Transmittal
  on your behalf for each Exchange Ratio you will accept, although the same
  shares of Viacom Common Stock cannot be tendered for exchange at more than
  one Exchange Ratio.
 
  If more shares of Viacom Common Stock than are necessary to reach the
Trigger Amount are validly tendered and not properly withdrawn in the Exchange
Offer at Exchange Ratios at or below the Final Exchange Ratio as provided in
the Offering Circular - Prospectus, the shares of Viacom Common Stock so
tendered and not properly withdrawn at such Exchange Ratios shall be accepted
for exchange on a pro rata basis in accordance with the terms set forth in the
Offering Circular - Prospectus under "The Exchange Offer--Terms of the
Exchange Offer." Upon acceptance by Viacom of the shares of Viacom Common
Stock tendered herewith, stockholders will be deemed to have accepted the
shares of VII Cable Class A Common Stock exchanged therefor and will be deemed
to have relinquished all rights with respect to the shares of Viacom Common
Stock so accepted.
 
  The Exchange Offer is made solely by the Offering Circular - Prospectus and
the related Letter of Transmittal and is being made to all holders of shares
of Viacom Common Stock. Viacom is not aware of any state where the making of
the Exchange Offer is prohibited by administrative or judicial action pursuant
to any valid state statute. If Viacom becomes aware of any valid state statute
prohibiting the making of the Exchange Offer or the acceptance of shares of
Viacom Common Stock pursuant thereto, Viacom will make a good faith effort to
comply with such state statute. If, after such good faith effort, Viacom
cannot comply with such state statute, the Exchange Offer will not be made to
(nor will tenders be accepted from or on behalf of) the holders of shares of
Viacom Common Stock in such state. In any jurisdiction where the securities,
blue sky or other laws require the Exchange Offer to be made by a licensed
broker or dealer, the Exchange Offer shall be deemed to be made on behalf of
Viacom by one or more registered brokers or dealers licensed under the laws of
such jurisdiction.
 
  If you wish to have us tender any or all of your shares of Viacom Common
Stock, please so instruct us by completing, executing and returning to us the
attached instruction form. An envelope to return your instructions is
enclosed. Please forward your instructions to us in ample time to permit us to
submit a tender on your behalf on or prior to the Expiration Date. IF YOU
AUTHORIZE THE TENDER OF YOUR SHARES OF VIACOM COMMON STOCK, ALL SUCH SHARES
WILL BE TENDERED UNLESS OTHERWISE SPECIFIED ON THE ATTACHED INSTRUCTION FORM.
