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

Other Transfer Arrangements

         It is the intention of the Charter Reporting Persons that immediately
prior to the consummation of the transactions contemplated by the Asset Purchase

Holdings as a contribution to capital, Charter Ventures will transfer the 37,000
shares of Series D Preferred Stock of the Issuer it holds to Charter Holdings as
a distribution, and Charter Holdings will transfer the Charter Warrants it will
receive from Charter Holdco and the 37,000 shares of Series D Preferred Stock it
will receive from Charter Ventures to CC Systems as a contribution to capital,
which will leave CC Systems holding, immediately prior to closing of the Asset
Purchase Agreement, 75,000 shares of Series D Preferred Stock of the Issuer and
the Charter Warrants. After closing, none of Vulcan Ventures, Mr. Allen, the
Charter Reporting Persons or CC Systems will beneficially own any securities of
the Issuer.

                             ASSIGNMENT AND CONSENT


      This Assignment and Consent is entered into by and among Charter
Communications Holding Company, LLC, a Delaware limited liability company
("Holdco"), CC Systems, LLC, a Delaware limited liability company and an
indirectly wholly owned subsidiary of Holdco ("CC Systems"), and Vulcan Ventures
Incorporated, a Washington corporation ("Vulcan"), on this 20th day of December,
2001.

                                    Recitals

      A.    Pursuant to the Asset Purchase Agreement, dated as of September 28,
2001 (the "Asset Purchase Agreement"), by and among Holdco and High Speed Access
Corp., a Delaware corporation ("HSA"), Holdco has agreed, subject to the terms
and conditions set forth therein, to purchase certain assets from, and assume
certain liabilities of, HSA.

      B.    Pursuant to the Stock Purchase Agreement, dated as of September 28,
2001 (the "Stock Purchase Agreement"), between Vulcan and Holdco, Holdco has
agreed to purchase from Vulcan certain shares of preferred stock issued by HSA,
the closing of which purchase is conditioned upon closing of the transactions
contemplated by the Asset Purchase Agreement.

      C.    Pursuant to the License Agreement, dated as of September 28, 2001
(the "License Agreement"), between Holdco, HSA and HSA International, Inc., a
Delaware corporation ("HSA International"), entered into in connection with the
Asset Purchase Agreement, Holdco granted to HSA and HSA International limited
licenses to use certain software to be acquired by Holdco from HSA pursuant to
the Asset Purchase Agreement.

      D.    Pursuant to the Non-Solicitation Agreements entered into in
connection with the Asset Purchase Agreement, each dated as of September 28,
2001, between Holdco and each of Daniel O'Brien and Gregg Hodges (each person
being party to only one such agreement) (collectively, the "Non-Solicitation
Agreements"), Messrs. O'Brien and Hodges agreed not to solicit certain HSA
employees to terminate employment with Holdco or any of its Affiliates.

      E.    Neither the License Agreement nor the Non-Solicitation Agreements
restrict Holdco's ability to assign those agreements and, pursuant to Section
12.05 of the Asset Purchase Agreement, Holdco may, without the consent of HSA,
assign to any of its Affiliates its right to acquire part or all of the Acquired
Assets, including the right to become an "Approved Company" as provided in
Section 8.04 of the Asset Purchase Agreement, and to assume the Assumed
Liabilities (such right, the "Purchase and Assumption Right"), provided that
Holdco is not released from its obligations or liabilities under the Asset
Purchase Agreement.






      F.    CC Systems is an indirectly wholly owned subsidiary and an Affiliate
of Holdco.

      G.    The Stock Purchase Agreement conditions its assignment upon the
consent of the non-assigning party.

      H.    Holdco desires to assign the License Agreement, the Stock Purchase
Agreement, the Non-Solicitation Agreements and the Purchase and Assumption Right
to CC Systems, CC Systems desires to assume such agreements and the Purchase and
Assumption Right and Vulcan desires to consent to the assignment of the Stock
Purchase Agreement by Holdco to CC Systems.

      NOW THEREFORE, in recognition of the above and for other good and valuable
consideration the receipt of which is hereby acknowledged, the parties hereto
hereby agree as follows:

      1.    Defined Terms. Capitalized terms used and not otherwise defined
herein shall have the meanings assigned such terms in the Asset Purchase
Agreement.

      2.    Assignment and Assumption.

            (i) Holdco hereby assigns the Purchase and Assumption Right and all
of its rights under the License Agreement, the Stock Purchase Agreement and the
Non-Solicitation Agreements to CC Systems. Holdco also assigns to CC Systems all
of its rights to have assigned or transferred to it any contract, agreement or
other instrument that is required to be assigned or transferred to Holdco by HSA
pursuant to the Asset Purchase Agreement (the "Acquired Agreements").

            (ii) CC Systems agrees to assume all of Holdco's liabilities and
fully perform all of Holdco's obligations under the Purchase and Assumption
Right, the License Agreement, the Stock Purchase Agreement, the Non-Solicitation
Agreements and the Acquired Agreements.

      3.    No Release. Holdco agrees that, notwithstanding the assignment of
the Purchase and Assumption Right by Holdco to CC Systems, such assumption does
not effect any release of Holdco from its liabilities and obligations under the
Asset Purchase Agreement beyond that permitted by the Asset Purchase Agreement.
Holdco further agrees that, notwithstanding the assumption of Holdco's
liabilities and obligations under the Stock Purchase Agreement by CC Systems,
such assumption does not effect any release of Holdco from its liabilities and
obligations under the Stock Purchase Agreement.

      4.    Consent by Vulcan. By signing below, Vulcan agrees that it consents
to the assignment of the Stock Purchase Agreement by Holdco to CC Systems.



                                       2




      5.    Choice of Law. This Assignment and Consent and the rights and
obligations of the parties hereunder shall be governed by and interpreted in
accordance with the laws of the State of New York, without reference to the
conflicts of laws principles thereof.

      6.    Counterparts. This Assignment and Consent may be executed in two or
more counterparts, any of which may be deemed an original, but all of which
taken together shall constitute one and the same instrument.

             [The balance of this page is intentionally left blank.]



                                       3




      IN WITNESS WHEREOF, each of the parties has caused this Assignment and
Consent to be executed on its behalf by its duly authorized officer.
