with the Full Turnkey Agreement, the "Network Services Agreements").

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


          Purchase Price


          The purchase price for the acquired assets is $81,100,000 in cash,
subject to adjustment as described below, 75,000 shares of the Issuer's Series D
Preferred Stock together with the cancellation of any rights to dividends with
respect to such shares, and the cancellation of all warrants to buy shares of
the Issuer's common stock held by Charter Holdco. The 75,000 shares of Series D
Preferred Stock include the shares to be acquired by Charter Holdco from Vulcan
Ventures pursuant to the Stock Purchase Agreement described below.

           Purchase Price Adjustment

          At closing, Charter Holdco will hold back $750,000 for purposes of
purchase price adjustments described in the following three paragraphs (the
"Adjustment Holdback"). Charter Holdco will also hold back $4,000,000 for
purposes of settling indemnity claims under the Asset Purchase Agreement (the
"Indemnification Holdback").

          The purchase price will be increased at closing by the amount of
current assets acquired by Charter Holdco, which will include items such as (i)
certain accounts receivable from Charter Holdco related to the Second NSA
Agreement, (ii) certain security deposits and prepayments and (iii) certain
receivables from customers of the Cable Modem Business.

          The purchase price will be decreased at closing by the sum of (i) the
liabilities assumed by Charter Holdco under the capital leases assumed as part
of the acquired assets, (ii) certain current liabilities incurred on or prior to
closing related to the Cable Modem Business, including accounts payable, (iii)
accrued costs related to employees of the Issuer to be hired by Charter Holdco,
and (iv) certain charges payable by the Issuer to Charter Holdco in connection
with the pre-closing operation of the Cable Modem Business.

          Any decreases in the purchase price will be made first from the
Adjustment Holdback and all adjustments to the purchase price will be made at or
following closing.

           Covenants and Agreements of the Issuer and Charter Holdco

          Among other covenants, the Issuer agreed that it would conduct the
Cable Modem Business in the ordinary course until closing and use commercially
reasonable efforts to preserve the acquired assets and the Cable Modem Business
and relationships with persons with whom it has significant business dealings in
connection with the Cable Modem Business.

          The parties agreed that Launch Fees payable by the Issuer to Charter
Holdco under the Second NSA Agreement will not be payable unless the Asset
Purchase Agreement is terminated in accordance with its terms. The parties also
agreed that the Second NSA Agreement will terminate upon closing and that
Charter HoldCo will use its best efforts to cause the Full Turnkey Agreement to
terminate as of the closing without liability to any party thereto.

           Conditions to Closing

          The closing of the Asset Purchase Agreement is subject to a number of
conditions, including approval by (i) the holders of at least a majority of the
Issuer's preferred and common stock, voting together as a single class (with the
Series D Preferred Stock voting on an "as converted to common stock" basis),
(ii) the holders of at least two-thirds of the Series D Preferred Stock, voting
separately as a single class and (iii) the holders of at least a majority of the
Issuer's preferred and common stock actually voting on the transaction other
than Charter Holdco, Vulcan Ventures, or any of their respective affiliates, or
any officers and directors of the Issuer that are entitled to receive a payment
in the nature of compensation contingent upon consummation of the transactions
(with the Series D Preferred Stock voting on an "as converted to common stock"
basis).

          The holders of over 51% of the Issuer's issued and outstanding common
and preferred stock, counted together as a single class (including Charter
Holdco, Vulcan Ventures and their affiliates and executive officers and
directors of the Issuer), and the holders of all the Issuer's Series D Preferred
Stock have agreed to vote in favor of the Asset Purchase Agreement. See "Voting
Agreement" below. The holders of common stock and preferred stock of the Issuer
other than Charter Holdco, Vulcan Ventures, and their respective affiliates, and
the executive officers and directors of the Issuer are not parties to or
otherwise bound by the Voting Agreement; such holders will be afforded an
opportunity to consider the transaction at a special meeting of the stockholders
of the Issuer.

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


          Closing is also conditioned upon termination of the Hart-Scott-Rodino
waiting period and the absence of any material adverse change in the acquired
assets or the Cable Modem Business.

          Termination

          If the Asset Purchase Agreement is terminated due to a party's
negligent or willful failure to perform its obligations, that party must pay the
reasonable out-of-pocket expenses incurred by the other party prior to the date
of termination, including legal and banking fees, together with certain fees and
expenses chargeable under the Management Agreement. See "Management Agreement"
below.

          The Issuer has the right to entertain unsolicited acquisition
proposals that the Issuer's board of directors determines in its good faith
judgment are more favorable to the Issuer's stockholders than the Asset Purchase
Agreement and to terminate the Asset Purchase Agreement if the Issuer enters
into a definitive agreement providing for such an alternative acquisition. The
Asset Purchase Agreement does not provide for the payment of breakup fees or
other penalties if the Issuer accepts such an alternative acquisition proposal;
however, Charter Holdco will be entitled to reimbursement of its reasonable
out-of-pocket expenses prior to the date of termination, including legal and
banking fees, together with certain fees and expenses chargeable under the
Management Agreement.

          The Asset Purchase Agreement may also be terminated by the Issuer or
Charter Holdco if the closing has not occurred on or prior to March 31, 2002.

          Indemnification

          The Issuer agreed to indemnify Charter Holdco against all claims
arising from breaches of its representations, warranties or covenants, the
excluded liabilities or the pre-closing operation of the Cable Modem Business.
The Issuer's pre-closing covenants and representations and warranties will
survive for a period of eighteen months after the closing, except that
representations and warranties regarding title to the acquired assets will
survive in perpetuity, the representations and warranties related to taxes will
survive until after the statue of limitations has expired with respect to claims
thereto and representations and warranties with respect to certain benefit plans
and environmental matters will survive for twenty-four months after the closing.

          The Issuer will have no liability for claims arising from breaches of
its representations, warranties or pre-closing covenants unless the damages in
the aggregate for such breaches exceed $250,000, in which case, Charter Holdco
is entitled to reimbursement from the first dollar of such damages. In addition,
payments for damages related to claims arising from breaches of the Issuer's
representations, warranties or pre-closing covenants will be made solely from
and only to the extent of the $4,000,000 Indemnification Holdback.

          Charter Holdco is entitled to reimbursement from the first dollar of
damages related to breaches of post-closing covenants, the representations and
warranties related to title, taxes, certain benefit plans and environmental
matters, the excluded liabilities, the operation of the Cable Modem Business
before the closing and actual common law fraud, and such damages are not limited
to the $4,000,000 Indemnification Holdback.

          Twelve months after closing, $2 million of the Indemnification
Holdback will be released to the Issuer, less the aggregate amount of
indemnification claims previously satisfied from the Indemnification Holdback
and any pending indemnification claims, and the balance, less previously paid
and any pending indemnification claims, will be released to the Issuer eighteen
months after the closing.

          The foregoing description of the Asset Purchase Agreement is not, and
does not purport to be, complete and is qualified in its entirety by reference
to the Asset Purchase Agreement, a copy of which is filed herewith as Exhibit
10.1.

Management Agreement

          In connection with the Asset Purchase Agreement, the Issuer and
Charter entered into a Services and Management Agreement (the "Management
Agreement") pursuant to which the Issuer agreed to allow Charter to perform
certain services previously performed by the Issuer under a the Network Services
Agreements.

          Services

          In the Management Agreement, Charter agreed to perform the services
described in the Full Turnkey Agreement relating to the installation of internet
access to Charter's residential and commercial subscribers. Charter also agreed
to procure, at

CUSIP NO. 42979U-102                 13D                     Page 11 of 18 Pages
---------------------                                       --------------------


its cost, after deployment of the modems owned by the Issuer at the CMB sites or
in transit (the "Modem Inventory"), the cable modems necessary for such
installation services. The Issuer and Charter agreed that they would each have
the right to perform, at their respective costs, the marketing of internet
access service to Charter's subscribers.

          In the Management Agreement, the parties agreed that Charter would
have the right, at its option, to perform certain additional services in order
to facilitate the transition of the Cable Modem Business operations from the
Issuer to Charter Holdco. These additional services included Charter's right to
participate in policy-making by the Issuer relating to the customer care and
operation of the Issuer's Louisville, Kentucky network operations center, the
responsibility for making decisions relating to pursuit, termination and
prioritization of the Cable Modem Business projects relating to engineering
design and information systems infrastructure and operation, determining which
employees will be assigned to perform any of the services covered under the
Management Agreement, formulating and supervising programs, policies and
procedures relating to the Cable Modem Business and establishing and directing
the technical standards and procedures related to the Cable Modem Business.

          Installation and Marketing Fees

          In connection with Charter's performance of the installation and
marketing services described above, the Issuer agreed to pay Charter the
following amounts for each new subscriber connection added during the period
expiring when neither of the Network Services Agreements is in effect or the
Management Agreement is earlier terminated according to its terms: an
installation fee of $115, a marketing fee of $50, $150 for each Com 21 modem
installed and $100 for each DOCSIS modem installed (other than modems obtained
from the Modem Inventory). These amounts accrue as a liability of the Issuer
during the pre-closing period. If the Asset Purchase Agreement closes, the
amounts due to Charter will be waived by Charter. If the Management Agreement is
terminated prior to termination of the Asset Purchase Agreement, accrued amounts
will not be payable until the earlier of closing of the Asset Purchase Agreement
(in which case the amounts accrued are waived) or termination of the Asset
Purchase Agreement, in which case the amounts accrued become immediately due and
payable to Charter.

          Incremented Costs

          In the Management Agreement, Charter agreed to pay all costs and
expenses ("incremental costs") incurred by the Issuer to the extent relating to
and arising out of Charter's exercise of its right to perform the additional
services described above. However, Charter's reimbursement obligation does not
extend to costs incurred by the Issuer in conducting the Cable Modem Business in
the ordinary course as required in the Asset Purchase Agreement or to costs that
the Issuer would have incurred even without Charter's performance of such
additional services. If incremental costs are less than or equal to $100,000,
Charter must pay the Issuer for those incremental costs at the closing of the
Asset Purchase Agreement. Amounts in excess of $100,000 are payable by Charter
within 30 days of being invoiced for such costs. If the Issuer terminates the
Management Agreement for reasons other than breaches of the Agreement by Charter
or other misconduct by Charter, Charter does not have to pay any remaining
outstanding incremental costs.

          The foregoing description of the Management Agreement is not, and does
not purport to be, complete and is qualified in its entirety by reference to the
Management Agreement, a copy of which is filed herewith as Exhibit 10.2.

          Billing Letter Agreement

          In addition, Charter has elected under the November 25, 1998 Network
Services Agreement to assume responsibility to bill cable subscribers and
collect revenues in connection with the Cable Modem Business. The Issuer has
agreed to assist Charter in the transition of this billing function from the
Issuer to Charter, to deliver certain of its databases it used in the billing
function, to make technical support personnel available to Charter and to
provide Charter to free access to the Issuer's data exchange/software interface.

License Agreement

          In connection with the Asset Purchase Agreement, the Issuer, HSA
International, Inc., a subsidiary of the Issuer (referred to collectively with
the Issuer), and Charter Holdco entered into a License Agreement (the "License
Agreement") pursuant to which Charter Holdco granted the Issuer rights to use
certain intellectual property to be sold by the Issuer to Charter Holdco under
the Asset Purchase Agreement in the conduct of the Issuer's remaining
businesses.

          Licensed Rights

          These rights include domestic (U.S.) and international (non-U.S.)
software tools licenses which are royalty-free, non-transferable and
non-sublicensable licenses in HSA-created aspects and software for specified
applications.

          The Issuer may only use the domestic license in the operation of its
U.S. web-hosting and broadband ISP business to facilitate the winding down of
those businesses. The Issuer may only use the international license in the
operation of its non-U.S. consulting and Internet service provisioning
activities. The Issuer agreed that it would not use either license or related
intellectual property rights in any manner that competes with the business of
Charter Holdco or its affiliates.

          License Term

          The domestic license expires on the earlier of (i) such time as the
Issuer ceases its domestic ISP and web-hosting activities and (ii) June 30,
2002. The international license expires three years from the date of the closing
of the Asset Purchase Agreement.

Except to the extent of the grant of the licensed rights, Charter Holdco is the
sole and exclusive owner of all right, title and interest in the software tools
and international intellectual property rights and all portions and copies
thereof. The Issuer agreed that it would do nothing to impair Charter Holdco's

ITEM 5.   INTEREST IN SECURITIES OF THE ISSUER.

          Item 5 of the Schedule 13D is hereby amended and restated in its
entirety to read as follows:

          (a) As of the date of this Amendment, Vulcan Ventures, Mr. Allen and
each of the Charter Reporting Persons beneficially own 27,798,278 shares,
37,750,198 shares and 9,951,920 shares, respectively, of the Issuer's common
stock. Such shares include 7,576,139 shares and 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 38,000 shares and 37,000 shares of Series D Preferred
Stock held by Vulcan Ventures and Charter Ventures, respectively, and the shares
of common stock issuable upon exercise of the 2,575,153 warrants held by
Charter. 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.

          Vulcan Ventures', Mr. Allen's and the Charter Reporting Persons'
stockholdings, 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 41.9%, 49.5% and 14.5%, 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 and the Stock Purchase Agreement, including the transfer of
38,000 shares of Series D Preferred Stock by Vulcan Ventures to Charter Holdco
pursuant to the Stock Purchase Agreement and the subsequent transfer of all
75,000 shares of Series D Preferred Stock then held by Charter Holdco to the
Issuer and the cancellation of the Charter Warrants (as defined in the Asset
Purchase Agreement) pursuant to the Asset Purchase Agreement, Vulcan Ventures
and Mr. Allen will each beneficially own 20,222,139 shares of the Issuer's
common stock, which will represent approximately 34.4% of the Issuer's common
stock then outstanding, and none of the Charter Reporting Persons will hold any
securities of the Issuer. But see Items 4 and 6 for a description of termination
provisions and conditions to closing of the Asset Purchase Agreement and the
Stock Purchase Agreement.

          All of the percentages set forth in this Item 5(a) are based upon
58,809,052 shares of the Issuer's common stock outstanding as of June 30, 2001,
as reported by the Issuer in its Quarterly Report on Form 10-Q filed with the
Securities and Exchange Commission on August 14, 2001.

          To the best knowledge of Vulcan Ventures, Mr. Allen and the Charter
Reporting Persons, none of the other parties named in Item 2 owns any of the
Issuer's common stock, except as follows:

          William D. Savoy, Vice President and a Director of Vulcan Ventures and
a Director of Charter, Charter Holdco, and Charter Holdings, beneficially owns
immediately exercisable options to acquire 40,750 shares of the Issuer's common
stock. Mr. Savoy resigned as a Director of the Issuer on July 30, 2001. Vulcan
Ventures and the Charter Reporting Persons disclaim beneficial ownership of such
options.
