ITEM 3.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

         Item 3 of the Schedule 13D is hereby amended by adding the following:

         As more fully described in Item 6 below, Charter Holdco assigned to CC
Systems, LLC, a Delaware limited liability company and an indirect wholly-owned
subsidiary of Charter Holdings ("CC Systems"), the Stock Purchase Agreement
described in Item 6 of Amendment No. 6 to the Schedule 13D. CC Systems will
receive from Charter Holdings as a contribution to capital the $8 million
necessary to pay the cash purchase price for the 38,000 shares of Series D
Preferred Stock of the Issuer as provided in the Stock Purchase Agreement and
the funds required to pay the cash portion of the purchase price under the Asset
Purchase Agreement (collectively, the "acquisition funds"). Charter Holdings
will receive the acquisition funds from either or both of Charter Communications
Operating, LLC ("Charter Operating") or Falcon Cable Communications, LLC
("Falcon" and together with Charter Operating, the "Funding Subsidiaries"), each
of which is an indirectly wholly-owned subsidiary of Charter Holdco, as a
repayment of certain portions of intercompany receivables held by Charter
Holdings. The Funding Subsidiaries will obtain the acquisition funds from either
their working capital or drawdowns on their credit facilities.

         The credit facilities for Charter Operating were entered into on March
18, 1999 and consists of senior secured credit facilities arranged by Chase
Securities Inc., Nationsbanc Montgomery Securities LLC and TD Securities (USA)
Inc. These credit facilities are guaranteed by Charter Holdings and by Charter
Operating's subsidiaries and are secured by pledges of intercompany obligations
and ownership interests. These credit facilities include Tranche A and B term
loans and a revolving loan with a $1.25 billion borrowing limit. The final
maturity date for both the Tranche A term loan and the revolving loan is
September 18, 2007. The final maturity date for the Tranche B term loan is March
18, 2008. The revolving loan will likely be the portion drawn upon to fund the
purchases of stock and assets described above. The interest rate on the
revolving loan may be determined by two options, a base rate option, which is
generally the "prime rate" of interest plus a margin ranging from 1.5% to 2.25%
depending on the leverage ratio of Charter Operating and its subsidiaries and an
interbank eurodollar rate plus a margin ranging from 0.5% to 1.25% also
depending on the leverage ratio of Charter Operating and its subsidiaries. The
effective rate under Charter Operating's revolving loan will depend on the prime
rate and the margin applicable at the time of borrowing.

         The foregoing description of Charter Operating's credit facilities is
not, and does not purport to be, complete and is qualified in its entirety to
Charter Operating's Credit Agreement and the First, Second and Third Amendments
to that Credit Agreement, copies of which are filed herewith as Exhibits 10.2,
10.3, 10.4 and 10.5, respectively.

         Falcon's credit facilities with BankBoston, N.A., Bank of America, N.A.
and the Chase Manhattan Bank, as agents, were amended and restated as of
November 12, 1999, and are senior secured credit facilities guaranteed by
Falcon's direct parent, which is an affiliate of Charter Holdco, and by Falcon's
subsidiaries and are secured by pledges of intercompany obligations and
ownership interests. These credit facilities include Term Loans B and C, a
revolving loan with a $646 million borrowing limit and a supplemental revolving
loan with a $110 million borrowing limit. The final maturity dates for the
revolving loan and the supplemental revolving loan are December 29, 2006 and
December 31, 2007, respectively. The final maturity date for Term Loans B and C
are June 29, 2007 and December 31, 2007, respectively. Either or both of the
revolving loan and the supplemental revolving loan will likely be the portion of
Falcon's credit facilities drawn upon to fund the purchases of stock and assets
described above. The interest rate on the revolving loan and the supplemental
revolving loan may be determined by two options, a base rate option, which is
generally the "prime rate" of interest plus a margin ranging from 1.0% to 2.0%,
depending on the leverage ratio of Falcon and its subsidiaries and an interbank
eurodollar rate plus a margin ranging from 0.0% to 1.0%, also depending on the
leverage ratio of Falcon and its subsidiaries. The effective rate under Falcon's
revolving loan and supplemental revolving loan will depend on the prime rate and
the margin applicable at the time of borrowing.

         The foregoing description of Falcon's credit facilities is not, and
does not purport to be, complete and is qualified in its entirety to Falcon's
Form of Credit Agreement, a copy of which is filed herewith as Exhibit 10.6.

         In addition, the matters set forth in Item 6 under "Other Transfer
Arrangements" are incorporated in this Item 3 by reference as if fully set forth
herein.

ITEM 4.  PURPOSE OF TRANSACTION.

         Item 4 of the Schedule 13D is hereby amended by adding the following:

         In addition, the matters set forth in Item 6 are incorporated in this
Item 4 by reference as if fully set forth herein.

ITEM 5.  INTEREST IN SECURITIES OF THE ISSUER.

         Item 5(a) of the Schedule 13D is hereby amended and restated to read as
follows (except as otherwise noted):

         (a) As of the date of this Amendment No. 8, Vulcan Ventures, Mr. Allen
and each of the Charter Reporting Persons, beneficially own 27,798,278 shares,
37,825,704 shares and 10,027,426 shares, respectively, of the Issuer's common
stock. The

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


reported shares of Mr. Allen and each of the Charter Reporting Persons include
2,650,659 shares of common stock issuable upon exercise of warrants held by
Charter. The reported shares of Mr. Allen and each of the Charter Reporting
Persons include 7,376,767 shares of common stock that may be obtained upon
conversion (at the conversion price in effect as of the date hereof) of the
37,000 shares of Series D Preferred Stock held by Charter Ventures. The reported
shares of Mr. Allen also include 20,222,139 shares of common stock owned
directly by Vulcan Ventures and 7,576,139 shares of common stock that may be
obtained upon conversion (at the conversion price in effect as of the date
hereof) of the 38,000 shares of Series D Preferred Stock held by Vulcan
Ventures. The above conversion numbers for the Series D Preferred Stock are
based on a liquidation preference of $1,000 per share of Series D Preferred
Stock and a conversion price of $5.01875 per share of common stock.

         The stockholdings of Vulcan Ventures, Mr. Allen and the Charter
Reporting Persons, assuming immediate conversion of all of the shares of Series
D Preferred Stock into shares of common stock and exercise of the warrants,
represent approximately 40.9%, 48.4% and 14.1%, respectively, of the shares of
the Issuer's common stock outstanding, including shares issuable on such
conversion and exercise.

         Upon consummation of the transactions contemplated by the Asset
Purchase Agreement, the Stock Purchase Agreement, the Common Stock Purchase
Agreement, the Assignment and Consent and the transfers described under "Other
Transfer Arrangements" in Item 6 below, including the sale of 38,000 shares of
the Series D Preferred Stock by Vulcan Ventures to CC Systems pursuant to the
Stock Purchase Agreement and the Assignment and Consent, and including the
subsequent transfer of all 75,000 shares of Series D Preferred Stock to be held
by CC Systems immediately prior to closing of the Asset Purchase Agreement to
the Issuer at closing and the cancellation of the Charter Warrants (as defined
in the Asset Purchase Agreement) at closing, none of Vulcan Ventures, Mr. Allen
or the Charter Reporting Persons will beneficially own any securities of the
Issuer. But see Items 4 and 6 of the Schedule 13D for a description of
termination provisions and conditions to closing of the Asset Purchase
Agreement, the Stock Purchase Agreement and the Common Stock Purchase Agreement.

         The remaining text of Item 5(a) of the Schedule 13D beginning with the
words "[a]ll of the percentages set forth in this Item 5(a) . . . " is not
amended or restated in any way.

         Items 5(b) through Item 5(e) of the Schedule 13D remain true and
correct as of the date hereof and are not hereby amended.

ITEM 6.  CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT
         TO SECURITIES OF THE ISSUER.

         Item 6 of the Schedule 13D is hereby amended by adding the following:

Assignment and Consent
----------------------

         In connection with the transactions contemplated by the Asset Purchase
Agreement, Charter Holdco, CC Systems and Vulcan Ventures executed an Assignment
and Consent, dated as of December 20, 2001 ("Assignment and Consent") pursuant
to which Charter Holdco assigned to CC Systems its rights under the Stock
Purchase Agreement, the License Agreement and Charter Holdco's right to purchase
assets and assume liabilities under the Asset Purchase Agreement.

         The foregoing description of the Assignment and Consent is not, and
does not purport to be, complete and is qualified in its entirety by reference
to the Assignment and Consent, a copy of which is filed herewith as Exhibit
10.6.

Other Transfer Arrangements
---------------------------

         It is the intention of the Charter Reporting Persons that immediately
