     This registration statement covers the registration of 14,950,000 shares of
common stock offered by the registrant pursuant to an underwritten public
offering, which includes 1,950,000 shares of common stock issuable upon exercise
of the Underwriters' over-allotment option. This registration statement also
covers up to 1,808,407 shares of common stock to be offered to Cisco Systems,
Inc., Com21, Inc. and Microsoft Corporation in a concurrent offering that is not
underwritten. The concurrent offering consists of $7.5 million of common stock
offered to Cisco, $1 million of common stock offered to Com21, and $10 million
of common stock offered to Microsoft, in each case at the offering price, net of
the underwriting discount. Therefore, this registration statement contains two
forms of prospectus: one to be used in connection with the public offering and
the other to be used in connection with the concurrent offerings to Cisco, Com21
and Microsoft. The public offering prospectus and the concurrent offering
prospectus are identical in all respects except for the front cover pages, the
tables of contents, the descriptions of the plan of distribution and the
descriptions of legal matters. The alternate pages of the concurrent offering
prospectus are included herein after the final page of the public offering
prospectus and are labeled "Alternate Page for Concurrent Offering Prospectus."
Final forms of each prospectus will be filed with the Securities and Exchange
Commission under Rule 424(b).

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS

     The Registrant's Amended and Restated Certificate of Incorporation to be in
effect upon the closing of this offering (the "Certificate") provides that,
except to the extent prohibited by the Delaware General Corporation Law, as
amended (the "DGCL"), the Registrant's directors shall not be personally liable
to the Registrant or its stockholders for monetary damages for any breach of
fiduciary duty as directors of the Registrant. Under the DGCL, the directors
have a fiduciary duty to the Registrant which is not eliminated by this
provision of the Certificate and, in appropriate circumstances, equitable
remedies such as injunctive or other forms of non-monetary relief will remain
available. In addition, each director will continue to be subject to liability
under the DGCL for breach of the director's duty of loyalty to the Registrant
and its stockholders, for acts or omissions which are found by a court of
competent jurisdiction to be not in good faith or involving intentional
misconduct, for knowing violations of law, for actions leading to improper
personal benefit to the director, and for payment of dividends or approval of
stock repurchases or redemptions that are prohibited by DGCL. This provision
also does not affect the directors' responsibilities under any other laws, such
as the Federal securities laws or state or Federal environmental laws. The
Registrant has obtained liability insurance for its officers and directors.

     Section 145 of the DGCL empowers a corporation to indemnify its directors
and officers and to purchase insurance with respect to liability arising out of
their capacity or status as directors and officers. The Certificate provides
that the Registrant shall indemnify any person who was or is a party or is
threatened to be made a party to or becomes involved in any action, suit or
proceeding (whether civil, criminal, administrative or investigative) by reason
of the fact that such person is or was a director or officer of the Registrant,
or is or was serving at the request of the Registrant as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust,
employee benefit plan or other enterprise, against expenses (including
attorney's fees), judgments, fines and amounts paid in settlement reasonably
incurred by such person in connection with such action, suit or proceeding. The
DGCL provides further that the indemnification permitted thereunder shall not be
deemed exclusive of any other rights to which the directors and officers may be
entitled under the corporation's bylaws, any agreement, a vote of stockholders
or otherwise. The Registrant has entered into indemnification agreements with
each member of the Board of Directors providing for the indemnification of the
directors to the fullest extent authorized, permitted or allowed by Delaware
law.

                                      II-1
<PAGE>   4

     At present, there is no pending litigation or proceeding involving any
director, officer, employee or agent as to which indemnification will be
required or permitted under the Certificate. The Registrant is not aware of any
threatened litigation or proceeding that may result in a claim for such
indemnification.

ITEM 17. UNDERTAKINGS

     The undersigned Registrant hereby undertakes to provide to the Underwriter
at the closing specified in the Underwriting Agreement, certificates in such
denominations and registered in such names as required by the Underwriter to
permit prompt delivery to each purchaser.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act, and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the Registrant of expenses incurred
or paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of counsel the matter has
been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

     The undersigned Registrant hereby undertakes that:

     (1) For purposes of determining any liability under the Securities Act of
1933, the information omitted from the form of prospectus filed as part of this
registration statement in reliance upon Rule 430A and contained in a form of
prospectus filed by the registrant pursuant to Rule 424 (b)(1) or (4), or 497(h)
under the Securities Act of 1933, shall be deemed to be part of this
registration statement as of the time it was declared effective.

     (2) For the purpose of determining any liability under the Securities Act
of 1933, each post-effective amendment that contains a form of prospectus shall
be deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

behalf by the undersigned, thereunto duly authorized in the City of Denver,
State of Colorado, on this 3rd day of June, 1999.

               (g) The execution, delivery and performance of this Agreement by
          the Company and the consummation of the transactions contemplated
          hereby will not conflict with or result in a breach or violation of
          any of the terms or provisions of, or constitute a default under, any
          indenture, mortgage, deed of trust, loan agreement or other agreement
          or instrument to which the Company or any of its subsidiaries is a
          party or by which the Company or any of its subsidiaries is bound or

          subsidiaries is subject, nor will such actions result in any violation
          of the provisions of the charter or by-laws of the Company or any of

          by the Company and the consummation of the transactions contemplated
          hereby.

               (h) Except as described in the Registration Statement, there are
          no contracts, agreements or understandings between the Company and any
          person granting such person the right (other than rights which have
          been waived or satisfied) to require the Company to file a
          registration statement under the Securities Act with respect to any
          securities of the Company owned or to be owned by such person or to

                                       3

          securities in the securities registered pursuant to the Registration
          Statement or in any securities being registered pursuant to any other
          registration statement filed by the Company under the Securities Act.

               (i) Except as described in the Registration Statement, the
          Company has not sold or issued any shares of Common Stock during the
          six-month period preceding the date of the Prospectus, including any
          sales pursuant to Rule 144A under, or Regulations D or S of, the
          Securities Act, other than shares issued pursuant to employee benefit
          plans, qualified stock options plans or other employee compensation
          plans or pursuant to outstanding options, rights or warrants.

               (j) Neither the Company nor any of its subsidiaries has
          sustained, since the date of the latest audited financial statements
          included in the Prospectus, any material loss or interference with its
          business from fire, explosion, flood or other calamity, whether or not
          covered by insurance, or from any labor dispute or court or
          governmental action, order or decree, otherwise than as set forth or
          contemplated in the Prospectus; and, since such date, there has not
          been any change in the capital stock or long-term debt of the Company
          or any of its subsidiaries or any material adverse change, or any
          development involving a prospective material adverse change, in or
          affecting the general affairs, management, financial position,
          stockholders' equity or results of operations of the Company and its
          subsidiaries, otherwise than as set forth or contemplated in the
          Prospectus.

               (k) The historical and pro forma financial statements, together
          with the related notes, set forth in the Prospectus comply as to form
          in all material respects with the requirements of Regulation S-X under
          the Securities Act applicable to registration statements on Form S-1
          under the Securities Act. The historical financial statements
          (including the related notes and supporting schedules) filed as part
          of the Registration Statement or included in the Prospectus present
          fairly in all material respects the financial condition and results of
          operations of the entities purported to be shown thereby, at the dates
          and for the periods indicated, and have been prepared in conformity
          with generally accepted accounting principles applied on a consistent
          basis throughout the periods involved. The unaudited pro forma
          combined statement of operations has been prepared on a basis
          consistent with such historical statements of the Company, except for
          the pro forma adjustments specified therein, and gives effect to
          assumptions made on a reasonable basis and in good faith. The other

               (m) The Company and each of its subsidiaries have good and
          marketable title in fee simple to all real property and good and
          marketable title to all personal property owned by them, in each case
          free and clear of all liens, encumbrances and defects except such as
          do not materially affect the value of such property and do not
          materially interfere with the use made and proposed to be made of such
          property by the Company and its subsidiaries; and all real property
          and buildings held under lease by the Company and its subsidiaries are
          held by them under valid, subsisting and enforceable leases, with such
          exceptions as are not material and do not interfere with the use made

          and its subsidiaries.

               (n) The Company and each of its subsidiaries carry, or are
          covered by, insurance in such amounts and covering such risks as is

          patents, patent applications, trademarks, service marks, trade names,
          trademark registrations, service mark registrations, copyrights and
          licenses necessary for the conduct of their respective businesses and
          have no reason to believe that the conduct of their respective
          businesses will conflict with, and have not received any notice of any
          claim of conflict with, any such rights of others.

               (p) There are no legal or governmental proceedings pending to
          which the Company or any of its subsidiaries is a party or of which
          any property or assets of the Company or any of its subsidiaries is
          the subject which, if determined adversely to the Company or any of
          its subsidiaries, could reasonably be expected to have a material
          adverse effect on the consolidated financial position, stockholders'
          equity, results of operations, business or prospects of the Company
          and its subsidiaries; and to the best of the Company's knowledge, no
          such proceedings are threatened or contemplated by governmental
          authorities or threatened by others.

               (q) There are no contracts or other documents which are required

               (r) No relationship, direct or indirect, exists between or among
          the Company on the one hand, and the directors, officers,
          stockholders, customers or suppliers of the Company on the other hand,
          which is required to be described in the Prospectus which is not so
          described.

               (s) No labor disturbance by the employees of the Company exists
          or, to the knowledge of the Company, is imminent which could
          reasonably be expected to have a material adverse effect on the
          consolidated financial position, stockholders' equity, results of
          operations, business or prospects of the Company and its subsidiaries.

               (t) The Company has filed all federal, state and local income and
          franchise tax returns required to be filed through the date hereof and
          has paid all taxes due thereon, and no tax deficiency has been
          determined adversely to the Company or any of its subsidiaries which
          has had (nor does the Company have any knowledge of any tax deficiency
          which, if determined adversely to the Company or any of its
          subsidiaries, could reasonably be expected to have a material adverse
          effect on the consolidated financial position, stockholders' equity,
          results of operations, business or prospects of the Company and its
          subsidiaries.

               (u) The Company has developed a plan (the "Company Y2K Plan")
          intended to ensure that all computer hardware and software used in and
          material to the business of the Company and its subsidiaries is
          designed to be Year 2000 Compliant. The Company Y2K Plan includes
          reasonable steps to determine whether the failure of any suppliers or
          customers with which the Company or any subsidiary has a material
          relationship to be Year 2000 Compliant would have or would reasonably
          be expected to have a material adverse effect on the Company and
          assuming the consummation of the Company Y2K Plan, the occurrence of
          calendar year 2000 will not reasonably be expected to have a material
          adverse effect on the Company. For purposes of this subsection (u),
          "Date Data" means any data of any kind that consists of date
          information or which is otherwise derived from, dependent on or
          related to date information; "Date-Sensitive System" means any
          software, microcode or hardware system or component, including any
          electronic or electronically controlled system or component that
          processes any Date Data and that is installed, in development or on
          order, for internal or external use, or the provision or operation of
          which provides a benefit to customers, vendors, suppliers or any other
          party; and "Year 2000 Compliant" means (i) with respect to Date Data,
          that such data is in proper format and (ii) with respect to
          Date-Sensitive Systems, that each such system accurately processes all
          Date Data, including for the twentieth and twenty-first centuries,
          without loss of any functionality or performance, including, without
          limitation, calculating, comparing, sequencing, storing and displaying
          such Date Data (including all leap year considerations), when used as
          a stand-alone system or in combination with other software or
          hardware. The matters set forth in this

          director, officer, agent, employee or other person associated with or
          acting on behalf of the Company or any of its subsidiaries, has used

          2. Purchase of the Stock by the Underwriters. On the basis of the
representations and warranties contained in, and subject to the terms and
conditions of, this Agreement, the Company agrees to sell 13,000,000 shares of
the Firm Stock to the several Underwriters and each of the Underwriters,
severally and not jointly, agrees to purchase the number of shares of the Firm
Stock set opposite that Underwriter's name in Schedule 1 hereto. The respective
purchase obligations of the Underwriters with respect to the Firm Stock shall be
rounded among the Underwriters to avoid fractional shares, as the
Representatives may determine.

          In addition, the Company grants to the Underwriters an option to
purchase up to 1,950,000 shares of Option Stock. Such option is granted solely
for the purpose of covering over-allotments in the sale of Firm Stock and is
exercisable as provided in Section 4 hereof. Shares of Option Stock shall be
purchased severally for the account of the Underwriters in proportion to the
number of shares of Firm Stock set opposite the name of such Underwriters in
Schedule 1 hereto. The respective purchase obligations of each Underwriter with
respect to the Option Stock shall be adjusted by the Representatives so that no
Underwriter shall be obligated to purchase Option Stock other than in 100 share
lots. The price of both the Firm Stock and any Option Stock shall be $_____ per
share.

          The Company shall not be obligated to deliver any of the Stock to be
delivered on any Delivery Date (as hereinafter defined), as the case may be,
except upon payment for all the Stock to be purchased on such Delivery Date as
provided herein.

          3. Offering of Stock by the Underwriters.

          Upon authorization by the Representatives of the release of the Firm
Stock, the several Underwriters propose to offer the Firm Stock for sale
initially at the public offering price set forth on the cover page of the
Prospectus and otherwise upon the terms and conditions set forth in the
Prospectus.

          It is understood that 975,000 shares of the Firm Stock will initially
be reserved by the several Underwriters for offer and sale upon the terms and
conditions set forth in the Prospectus and in accordance with the rules and
regulations of the National Association of Securities Dealers, Inc. to employees
and other persons having relationships with the Company and its subsidiaries who
have heretofore delivered to the Representatives offers or indications of
interest to purchase shares of Firm Stock in form satisfactory to the
Representatives, and that any allocation of such Firm Stock among such persons
will be made in accordance with timely directions received by the
Representatives from the Company; provided, that under no circumstances will the
Representatives or any Underwriter be liable to the Company or to any such
person for any action taken or omitted in good faith in connection with such
offering to employees and other persons having relationships with the Company
and its subsidiaries. It is further understood that any shares of such Firm
Stock which are not purchased by such persons will be offered by the
Underwriters to the public upon the terms and conditions set forth in the
Prospectus.

the Firm Stock shall be made at the office of Weil, Gotshal & Manges LLP, 767
Fifth Avenue, New York, New York 10153, at 10:00 A.M., New York City time, on
the third full business day following the date of this Agreement or the fourth
business day if this Agreement is executed after 4:30 p.m. New York City time or
at such other date or place as shall be determined by agreement between the
Representatives and the Company. This date and time are sometimes referred to as
the "First Delivery Date." On the First Delivery Date, the Company shall deliver
or cause to be delivered certificates representing the Firm Stock to the
Representatives for the account of each Underwriter against payment to or upon
the order of the Company of the purchase price by wire transfer in immediately
available funds. Time shall be of the essence, and delivery at the time and
place specified pursuant to this Agreement is a further condition of the
obligation of each Underwriter hereunder. Upon delivery, the Firm Stock shall be
registered in such names and in such denominations as the Representatives shall
request in writing not less than two full business days prior to the First
Delivery Date.

          The option granted in Section 2 will expire 30 days after the date of
this Agreement and may be exercised in whole or in part from time to time by
written notice being given to the Company by the Representatives. Such notice
shall set forth the aggregate number of shares of Option Stock as to which the
option is being exercised, the names in which the shares of Option Stock are to
be registered, the denominations in which the shares of Option Stock are to be
issued and the date and time, as determined by the Representatives, when the
shares of Option Stock are to be delivered; provided, however, that this date
and time shall not be earlier than the First Delivery Date nor earlier than the
second business day after the date on which the option shall have been exercised
nor later than the third business day after the date on which the option shall
have been exercised. The date and time the shares of Option Stock are delivered
are sometimes referred to as a "Second Delivery Date" and the First Delivery
Date and any Second Delivery Date are sometimes each referred to as a "Delivery
Date."

          Delivery of and payment for the Option Stock shall be made at the
place specified in the first sentence of the first paragraph of this Section 4
(or at such other place as shall be determined by agreement between the
Representatives and the Company) at 10:00 A.M., New York City time, on such
Second Delivery Date. On such Second Delivery Date, the Company shall deliver or
cause to be delivered the certificates representing the Option Stock to the
Representatives for the account of each Underwriter against payment to or upon
the order of the Company of the purchase price by wire transfer in immediately
available funds. Time shall be of the essence, and delivery at the time and
place specified pursuant to this Agreement is a further condition of the
obligation of each Underwriter hereunder. Upon delivery, the Option Stock shall
be registered in such names and in such denominations as the Representatives
shall request in the aforesaid written notice.

          statement of a material fact or omit to state any material fact
          necessary in order to make the statements therein, in the light of the
          circumstances under which they were made when such Prospectus is

          material and is required to be stated therein or is necessary to make
          the statements therein not misleading.

               (c) All corporate proceedings and other legal matters incident to

               (h) With respect to the letter of PricewaterhouseCoopers LLP
          referred to in the preceding paragraph and delivered to the
          Representatives concurrently with the execution of this Agreement (the
          "initial letter"), the Company shall have furnished to the
          Representatives a letter (the "bring-down letter") of such

<PAGE>   15

          such firm with respect to the financial information and other matters
          covered by the initial letter and (iii) confirming in all material
          respects the conclusions and findings set forth in the initial letter.

               (i) The Company shall have furnished to the Representatives a
          certificate, dated such Delivery Date, of its Chairman of the Board,
          its President or a Vice President and its Chief Financial Officer
          stating that:

                    (i) The representations, warranties and agreements of the
               Company in Section 1 are true and correct as of such Delivery
               Date; the Company has complied with all its agreements contained
               herein; and the conditions set forth in Subsections (a) and (i)
               of this Section 7 have been fulfilled; and

                    (ii) As of the Effective Date, the Registration Statement
               and Prospectus did not include any untrue statement of a material
               fact and did not omit to state a material fact required to be
               stated therein or necessary to make the statements therein not
               misleading, and since the Effective Date no event has occurred
               which should have been set forth in a supplement or amendment to
               the Registration Statement or the Prospectus.

               (j) (i) Neither the Company nor any of its subsidiaries shall
          have sustained since the date of the latest audited financial
          statements included in the Prospectus any loss or interference with
          its business from fire, explosion, flood or other calamity, whether or
          not covered by insurance, or from any labor dispute or court or
          governmental action, order or decree, otherwise than as set forth or
          contemplated in the Prospectus or (ii) since such date there shall not
          have been any change in the capital stock or long-term debt of the
          Company or any of its subsidiaries or any change, or any development
          involving a prospective change, in or affecting the general affairs,
          management, financial position, stockholders' equity or results of
          operations of the Company and its subsidiaries, otherwise than as set
          forth or contemplated in the Prospectus, the effect of which, in any
          such case described in clause (i) or (ii), is, in the judgment of the
          Representatives, so material and adverse as to make it impracticable
          or inadvisable to proceed with the public offering or the delivery of
          the Stock being delivered on such Delivery Date on the terms and in
          the manner contemplated in the Prospectus.

               (k) Subsequent to the execution and delivery of this Agreement
          there shall not have occurred any of the following: (i) trading in
          securities generally on the New York Stock Exchange or the American
          Stock Exchange or in the over-the-counter market, or trading in any
          securities of the Company on any exchange or in the over-the-counter
          market, shall have been suspended or minimum prices shall have been
          established on any such exchange or such market by the Commission, by
          such exchange or by any other regulatory body or governmental
          authority having jurisdiction, (ii) a banking moratorium shall


                                       15
<PAGE>   16

          have been declared by Federal or state authorities, (iii) the United
          States shall have become engaged in hostilities, there shall have been
          an escalation in hostilities involving the United States or there
          shall have been a declaration of a national emergency or war by the
          United States or (iv) there shall have occurred such a material
          adverse change in general economic, political or financial conditions
          (or the effect of international conditions on the financial markets in
          the United States shall be such) as to make it, in the judgment of the
          Representatives impracticable or inadvisable to proceed with the
          public offering or delivery of the Stock being delivered on such
          Delivery Date on the terms and in the manner contemplated in the
          Prospectus.

               (l) The Nasdaq Stock Market shall have approved the Stock for
          inclusion in the National Market System, subject only to official
          notice of issuance and evidence of satisfactory distribution.

          All opinions, letters, evidence and certificates mentioned above or
elsewhere in this Agreement shall be deemed to be in compliance with the
provisions hereof only if they are in form and substance reasonably satisfactory
to counsel for the Underwriters.

          8. Indemnification and Contribution.

               (a) The Company shall indemnify and hold harmless each
          Underwriter, its officers and employees and each person, if any, who
          controls any Underwriter within the meaning of the Securities Act,
          from and against any loss, claim, damage or liability, joint or
          several, or any action in respect thereof (including, but not limited
          to, any loss, claim, damage, liability or action relating to purchases
          and sales of Stock), to which that Underwriter, officer, employee or
          controlling person may become subject, under the Securities Act or
          otherwise, insofar as such loss, claim, damage, liability or action
          arises out of, or is based upon, (i) any untrue statement or alleged
          untrue statement of a material fact contained in any Preliminary
          Prospectus, the Registration Statement or the Prospectus or in any
          amendment or supplement thereto, (ii) the omission or alleged omission
          to state in any Preliminary Prospectus, the Registration Statement or
          the Prospectus, or in any amendment or supplement thereto, or in any
          Blue Sky Application any material fact required to be stated therein
          or necessary to make the statements therein not misleading or (iii)
          any act or failure to act or any alleged act or failure to act by any
          Underwriter in connection with, or relating in any manner to, the
          Stock or the offering contemplated hereby, and which is included as
          part of or referred to in any loss, claim, damage, liability or action
          arising out of or based upon matters covered by clause (i) or (ii)
          above (provided that the Company shall not be liable under this clause
          (iii) to the extent that it is determined in a final judgment by a
          court of competent jurisdiction that such loss, claim, damage,
          liability or action resulted directly from any such acts or failures
          to act undertaken or omitted to be taken by such Underwriter through
          its gross negligence or willful misconduct), and shall reimburse each
          Underwriter and each such officer, employee or controlling person
          promptly


                                       16
<PAGE>   17

          upon demand for any legal or other expenses reasonably incurred by
          that Underwriter, officer, employee or controlling person in
          connection with investigating or defending or preparing to defend
          against any such loss, claim, damage, liability or action as such
          expenses are incurred; provided, however, that the Company shall not
          be liable in any such case to the extent that any such loss, claim,
          damage, liability or action arises out of, or is based upon, any
          untrue statement or alleged untrue statement or omission or alleged
          omission made in any Preliminary Prospectus, the Registration
          Statement or the Prospectus, or in any such amendment or supplement,
          in reliance upon and in conformity with written information concerning
          such Underwriter furnished to the Company through the Representatives
          by or on behalf of any Underwriter specifically for inclusion therein
          which information consists solely of the information specified in
          Section 8(e). The indemnification agreement set forth in this
          paragraph (a) with respect to any Preliminary Prospectus shall not
          inure to the benefit of any Underwriter from whom the person asserting
          any such losses, claims, damages, liabilities or expenses purchased
          the Stock which is the subject thereof (or to the benefit of any
          person controlling such Underwriter) if at or prior to the written
          confirmation of the sale of such Stock a copy of the Prospectus (or
          the Prospectus as supplemented) was not sent or delivered to such
          person and the untrue statement or omission of a material fact
          contained in such Preliminary Prospectus was corrected in the
          Prospectus (or in the Prospectus as supplemented) in any case where
          such sending is required by the Securities Act unless the failure is
          the result of noncompliance by the Company with paragraph 5(a) hereof.
          The foregoing indemnity agreement is in addition to any liability
          which the Company may otherwise have to any Underwriter or to any
          officer, employee or controlling person of that Underwriter.

               (b) Each Underwriter, severally and not jointly, shall indemnify
          and hold harmless the Company, its officers and employees, each of its
          directors and each person, if any, who controls the Company within the
          meaning of the Securities Act, from and against any loss, claim,
          damage or liability, joint or several, or any action in respect
          thereof, to which the Company or any such director, officer or
          controlling person may become subject, under the Securities Act or
          otherwise, insofar as such loss, claim, damage, liability or action
          arises out of, or is based upon, (i) any untrue statement or alleged
          untrue statement of a material fact contained (A) in any Preliminary
          Prospectus, the Registration Statement or the Prospectus or in any
          amendment or supplement thereto, or (B) in any Blue Sky Application or
          (ii) the omission or alleged omission to state in any Preliminary
          Prospectus, the Registration Statement or the Prospectus, or in any
          amendment or supplement thereto, or in any Blue Sky Application any
          material fact required to be stated therein or necessary to make the
          statements therein not misleading, but in each case only to the extent
          that the untrue statement or alleged untrue statement or omission or
          alleged omission was made in reliance upon and in conformity with
          written information concerning such Underwriter furnished to the
          Company through the Representatives by or on behalf of that
          Underwriter specifically for


                                       17
<PAGE>   18

          inclusion therein as set forth in Section 8(e), and shall reimburse
          promptly upon demand the Company and any such director, officer or
          controlling person for any legal or other expenses reasonably incurred
          by the Company or any such director, officer or controlling person in
          connection with investigating or defending or preparing to defend
          against any such loss, claim, damage, liability or action as such
          expenses are incurred. The foregoing indemnity agreement is in
          addition to any liability which any Underwriter may otherwise have to
          the Company or any such director, officer, employee or controlling
          person.

               (c) Promptly after receipt by an indemnified party under this
          Section 8 of notice of any claim or the commencement of any action,
          the indemnified party shall, if a claim in respect thereof is to be
          made against the indemnifying party under this Section 8, notify the
          indemnifying party in writing of the claim or the commencement of that
          action; provided, however, that the failure to notify the indemnifying
          party shall not relieve it from any liability which it may have under
          this Section 8 except to the extent it has been materially prejudiced
          by such failure and, provided further, that the failure to notify the
          indemnifying party shall not relieve it from any liability which it
          may have to an indemnified party otherwise than under this Section 8.
          If any such claim or action shall be brought against an indemnified
          party, and it shall notify the indemnifying party thereof, the
          indemnifying party shall be entitled to participate therein and, to
          the extent that it wishes, jointly with any other similarly notified
          indemnifying party, to assume the defense thereof with counsel
          reasonably satisfactory to the indemnified party. After notice from
          the indemnifying party to the indemnified party of its election to
          assume the defense of such claim or action, the indemnifying party
          shall not be liable to the indemnified party under this Section 8 for
          any legal or other expenses subsequently incurred by the indemnified
          party in connection with the defense thereof other than reasonable
          costs of investigation; provided, however, that the Representatives
          shall have the right to employ counsel to represent jointly the
          Representatives and those other Underwriters and their respective
          officers, employees and controlling persons who may be subject to
          liability arising out of any claim in respect of which indemnity may
          be sought by the Underwriters against the Company under this Section 8
          if, in the reasonable judgment of the Representatives either (i) there
          is an actual or potential conflict between the position of the Company
          and the Underwriters or (ii) there may be defenses available to it or
          them that are different from or additional to those available to the
          Company (in any of which events the Company shall not have the right
          to direct the defense of such action on behalf of the Representative
          or Representatives with respect to such different defenses), in any of
          which events such fees and expenses shall be borne by the Company. No
          indemnifying party shall (i) without the prior written consent of the
          indemnified parties (which consent shall not be unreasonably
          withheld), settle or compromise or consent to the entry of any
          judgment with respect to any pending or threatened claim, action, suit
          or proceeding in respect of which indemnification or contribution may
          be sought hereunder (whether or not the


                                       18
<PAGE>   19

          indemnified parties are actual or potential parties to such claim or
          action) unless such settlement, compromise or consent includes an
          unconditional release of each indemnified party from all liability
          arising out of such claim, action, suit or proceeding, or (ii) be
          liable for any settlement of any such action effected without its
          written consent (which consent shall not be unreasonably withheld),
          but if settled with the consent of the indemnifying party or if there
          be a final judgment of the plaintiff in any such action, the
          indemnifying party agrees to indemnify and hold harmless any
          indemnified party from and against any loss or liability by reason of
          such settlement or judgment.

               (d) If the indemnification provided for in this Section 8 shall
          for any reason be unavailable to or insufficient to hold harmless an
          indemnified party under Section 8(a) or 8(b) in respect of any loss,
          claim, damage or liability, or any action in respect thereof, referred
          to therein, then each indemnifying party shall, in lieu of
          indemnifying such indemnified party, contribute to the amount paid or
          payable by such indemnified party as a result of such loss, claim,
          damage or liability, or action in respect thereof, (i) in such
          proportion as shall be appropriate to reflect the relative benefits
          received by the Company on the one hand and the Underwriters on the
          other from the offering of the Stock or (ii) if the allocation
          provided by clause (i) above is not permitted by applicable law, in
          such proportion as is appropriate to reflect not only the relative
          benefits referred to in clause (i) above but also the relative fault
          of the Company on the one hand and the Underwriters on the other with
          respect to the statements or omissions which resulted in such loss,
          claim, damage or liability, or action in respect thereof, as well as
          any other relevant equitable considerations. The relative benefits
          received by the Company on the one hand and the Underwriters on the
          other with respect to such offering shall be deemed to be in the same
          proportion as the total net proceeds from the offering of the Stock
          purchased under this Agreement (before deducting expenses) received by
          the Company, on the one hand, and the total underwriting discounts and
          commissions received by the Underwriters with respect to the shares of
          the Stock purchased under this Agreement, on the other hand, bear to
          the total gross proceeds from the offering of the shares of the Stock
          under this Agreement, in each case as set forth in the table on the
          cover page of the Prospectus. The relative fault shall be determined
          by reference to whether the untrue or alleged untrue statement of a
          material fact or omission or alleged omission to state a material fact
          relates to information supplied by the Company or the Underwriters,
          the intent of the parties and their relative knowledge, access to
          information and opportunity to correct or prevent such statement or
          omission. The Company and the Underwriters agree that it would not be
          just and equitable if contributions pursuant to this Section were to
          be determined by pro rata allocation (even if the Underwriters were
          treated as one entity for such purpose) or by any other method of
          allocation which does not take into account the equitable
          considerations referred to herein. The amount paid or payable by an
          indemnified party as a result of the loss, claim, damage or liability,
          or action


                                       19
<PAGE>   20

          in respect thereof, referred to above in this Section shall be deemed
          to include, for purposes of this Section 8(d), any legal or other
          expenses reasonably incurred by such indemnified party in connection
          with investigating or defending any such action or claim.
          Notwithstanding the provisions of this Section 8(d), no Underwriter
          shall be required to contribute any amount in excess of the amount by
          which the total price at which the Stock underwritten by it and
          distributed to the public was offered to the public exceeds the amount
          of any damages which such Underwriter has otherwise paid or become
          liable to pay by reason of any untrue or alleged untrue statement or
          omission or alleged omission. No person guilty of fraudulent
          misrepresentation (within the meaning of Section 11(f) of the
          Securities Act) shall be entitled to contribution from any person who
          was not guilty of such fraudulent misrepresentation. The Underwriters'
          obligations to contribute as provided in this Section 8(d) are several
          in proportion to their respective underwriting obligations and not
          joint.

               (e) The Underwriters severally confirm and the Company
          acknowledges that the statements with respect to the public offering
          of the Stock by the Underwriters set forth in the last paragraph on
          the cover page of, and the information contained in paragraphs 3, 10,
          11, 12, 13, 14 and 16 under the caption "Underwriting" in, the
          Prospectus are correct and constitute the only information concerning
          such Underwriters furnished in writing to the Company by or on behalf
          of the Underwriters specifically for inclusion in the Registration
          Statement and the Prospectus.

          9. Defaulting Underwriters.

          If, on either Delivery Date, any Underwriter defaults in the
performance of its obligations under this Agreement, the remaining
non-defaulting Underwriters shall be obligated to purchase the Stock which the
defaulting Underwriter agreed but failed to purchase on such Delivery Date in
the respective proportions which the number of shares of the Firm Stock set
opposite the name of each remaining non-defaulting Underwriter in Schedule 1
hereto bears to the total number of shares of the Firm Stock set opposite the
names of all the remaining non-defaulting Underwriters in Schedule 1 hereto;
provided, however, that the remaining non-defaulting Underwriters shall not be
obligated to purchase any of the Stock on such Delivery Date if the total number
of shares of the Stock which the defaulting Underwriter or Underwriters agreed
but failed to purchase on such date exceeds 9.09% of the total number of shares
of the Stock to be purchased on such Delivery Date, and any remaining
non-defaulting Underwriter shall not be obligated to purchase more than 110% of
the number of shares of the Stock which it agreed to purchase on such Delivery
Date pursuant to the terms of Section 3. If the foregoing maximums are exceeded,
the remaining non-defaulting Underwriters, or those other underwriters
satisfactory to the Representatives who so agree, shall have the right, but
shall not be obligated, to purchase, in such proportion as may be agreed upon
among them, all the Stock to be purchased on such Delivery Date. If the
remaining Underwriters or other underwriters satisfactory to the Representatives
do not elect to purchase the shares which the defaulting Underwriter or
Underwriters agreed but failed to purchase on such Delivery Date, this Agreement
(or, with


                                       20
<PAGE>   21

respect to the Second Delivery Date, the obligation of the Underwriters to
purchase, and of the Company to sell, the Option Stock) shall terminate without
liability on the part of any non-defaulting Underwriter or the Company, except
that the Company will continue to be liable for the payment of expenses to the
extent set forth in Sections 6 and 11. As used in this Agreement, the term
"Underwriter" includes, for all purposes of this Agreement unless the context
requires otherwise, any party not listed in Schedule 1 hereto who, pursuant to
this Section 9, purchases Firm Stock which a defaulting Underwriter agreed but
failed to purchase.

          Nothing contained herein shall relieve a defaulting Underwriter of any
liability it may have to the Company for damages caused by its default. If other
underwriters are obligated or agree to purchase the Stock of a defaulting or
withdrawing Underwriter, either the Representatives or the Company may postpone
the Delivery Date for up to seven full business days in order to effect any
changes that in the opinion of counsel for the Company or counsel for the
Underwriters may be necessary in the Registration Statement, the Prospectus or
in any other document or arrangement.

          10. Termination. The obligations of the Underwriters hereunder may be
terminated by the Representatives by notice given to and received by the Company
prior to delivery of and payment for the Firm Stock if, prior to that time, any
of the events described in Sections 7(i) or 7(j), shall have occurred or if the
Underwriters shall decline to purchase the Stock for any reason permitted under
this Agreement.

          11. Reimbursement of Underwriters' Expenses. If (a) the Company shall
fail to tender the Stock for delivery to the Underwriters by reason of any
failure, refusal or inability on the part of the Company to perform any
agreement on its part to be performed, or because any other condition of the
Underwriters' obligations hereunder required to be fulfilled by the Company is
not fulfilled, the Company will reimburse the Underwriters for all reasonable
out-of-pocket expenses (including fees and disbursements of counsel) incurred by
the Underwriters in connection with this Agreement and the proposed purchase of
the Stock, and upon demand the Company shall pay the full amount thereof to the
Representative(s). If this Agreement is terminated pursuant to Section 9 by
reason of the default of one or more Underwriters, the Company shall not be
obligated to reimburse any defaulting Underwriter on account of those expenses.

          12. Notices, etc. All statements, requests, notices and agreements
hereunder shall be in writing, and:

               (a) if to the Underwriters, shall be delivered or sent by mail,
          telex or facsimile transmission to Lehman Brothers Inc., Three World
          Financial Center, New York, New York 10285, Attention: Syndicate
          Department (Fax: 212-526-6588), with a copy, in the case of any notice
          pursuant to Section 11(d), to the Director of Litigation, Office of
          the General Counsel, Lehman Brothers Inc., 3 World Financial Center,
          10th Floor, New York, NY 10285;

<PAGE>   22

               (b) if to the Company shall be delivered or sent by mail, telex
          or facsimile transmission to the address of the Company set forth in
          the Registration Statement, Attention: John Hundley (Fax: (502)
          515-3101);

provided, however, that any notice to an Underwriter pursuant to Section 8(c)
shall be delivered or sent by mail, telex or facsimile transmission to such
Underwriter at its address set forth in its acceptance telex to the
Representatives, which address will be supplied to any other party hereto by the
Representatives upon request. Any such statements, requests, notices or
agreements shall take effect at the time of receipt thereof. The Company shall
be entitled to act and rely upon any request, consent, notice or agreement given
or made on behalf of the Underwriters by Lehman Brothers Inc.

          13. Persons Entitled to Benefit of Agreement. This Agreement shall
inure to the benefit of and be binding upon the Underwriters, the Company, and
their respective successors. This Agreement and the terms and provisions hereof
are for the sole benefit of only those persons, except that (A) the
representations, warranties, indemnities and agreements of the Company contained
in this Agreement shall also be deemed to be for the benefit of the person or
persons, if any, who control any Underwriter within the meaning of Section 15 of
the Securities Act and (B) the indemnity agreement of the Underwriters contained
in Section 8(b) of this Agreement shall be deemed to be for the benefit of
directors of the Company, officers of the Company who have signed the
Registration Statement and any person controlling the Company within the meaning
of Section 13 of the Securities Act. Nothing in this Agreement is intended or
shall be construed to give any person, other than the persons referred to in
this Section 16, any legal or equitable right, remedy or claim under or in
respect of this Agreement or any provision contained herein.

          14. Survival. The respective indemnities, representations, warranties
and agreements of the Company and the Underwriters contained in this Agreement
or made by or on behalf on them, respectively, pursuant to this Agreement, shall
survive the delivery of and payment for the Stock and shall remain in full force
and effect, regardless of any investigation made by or on behalf of any of them
or any person controlling any of them.

          15. Definition of the Terms "Business Day" and "Subsidiary". For
purposes of this Agreement, (a) "business day" means each Monday, Tuesday,
Wednesday, Thursday or Friday which is not a day on which banking institutions
in New York are generally authorized or obligated by law or executive order to
close and (b) "subsidiary" has the meaning set forth in Rule 405 of the Rules
and Regulations.

          16. Governing Law. This Agreement shall be governed by and construed
in accordance with the laws of New York.

          17. Counterparts. This Agreement may be executed in one or more
counterparts and, if executed in more than one counterpart, the executed
counterparts shall each be deemed to be an original but all such counterparts
shall together constitute one and the same instrument.

Ladies and Gentlemen:

               The undersigned understands that you and certain other firms
propose to enter into an Underwriting Agreement (the "Underwriting Agreement")
providing for the purchase by you and such other firms (the "Underwriters") of
shares (the "Shares") of Common Stock, par value $.01 per share (the "Common
Stock"), of High Speed Access Corp. (the "Company") and that the Underwriters
propose to reoffer the Shares to the public (the "Offering").

               In consideration of the execution of the Underwriting Agreement
by the Underwriters, and for other good and valuable consideration, the
undersigned hereby irrevocably agrees that, without the prior written consent of
Lehman Brothers Inc., the undersigned will not, directly or indirectly, (1)
offer for sale, sell, pledge, or otherwise dispose of (or enter into any
transaction or device that is designed to, or could be expected to, result in
the disposition by any person at any time in the future of) any shares of Common
Stock (including, without limitation, shares of Common Stock that may be deemed
to be beneficially owned by the undersigned in accordance with the rules and
regulations of the Securities and Exchange Commission and shares of Common Stock
that may be issued upon exercise of any option or warrant) or securities
convertible into or exchangeable for Common Stock (other than the Shares) owned
by the undersigned on the date of execution of this Lock-Up Letter Agreement or
on the date of the completion of the Offering, or (2) enter into any swap or
other derivatives transaction that transfers to another, in whole or in part,
any of the economic benefits or risks of ownership of such shares of Common
Stock, whether any such transaction described in clause (1) or (2) above is to
be settled by delivery of Common Stock or other securities, in cash or
otherwise, for a period of 180 days after the date of the final Prospectus
relating to the Offering.




<PAGE>   27


               In furtherance of the foregoing, the Company and its Transfer
Agent are hereby authorized to decline to make any transfer of securities if
such transfer would constitute a violation or breach of this Lock-Up Letter
Agreement.

               It is understood that, if the Company notifies you that it does
not intend to proceed with the Offering, if the Underwriting Agreement does not
become effective, or if the Underwriting Agreement (other than the provisions
thereof which survive termination) shall terminate or be terminated prior to
payment for and delivery of the Shares, we will be released from our obligations
under this Lock-Up Letter Agreement.

               The undersigned understands that the Company, the Underwriters
and the stockholders selling shares in the Offering will proceed with the
Offering in reliance on this Lock-Up Letter Agreement.

               The undersigned hereby represents and warrants that the
undersigned has full power and authority to enter into this Lock-Up Letter
Agreement and that, upon request, the undersigned will execute any additional
documents necessary in connection with the enforcement hereof. Any obligations
of the undersigned shall be binding upon the heirs, personal representatives,
successors and assigns of the undersigned.

             Re:      High Speed Access Corp. Registration Statement on Form S-1
                      for Delaware Shares of Common Stock

Ladies and Gentlemen:

             We have acted as counsel to High Speed Access Corp., a Delaware
corporation (the "Company"), in connection with the proposed issuance and sale
by the Company of up to 16,758,407 shares of the Company's Common Stock (the
"Shares") pursuant to the Company's Registration Statement on Form S-1 (the
"Registration Statement") filed with the Securities and Exchange Commission
under the Securities Act of 1933, as amended (the "Act").

             This opinion is being furnished in accordance with the requirements
of Item 16(a) of Form S-1 and Item 601(b)(5)(i) of Regulation S-K.

             We have reviewed the Company's charter documents and the corporate
proceedings taken by the Company in connection with the issuance and sale of the
Shares. Based on such review, we are of the opinion that the Shares have been
duly authorized, and if, as and when issued in accordance with the Registration
Statement and the related prospectus (as amended and supplemented through the
date of issuance) will be legally issued, fully paid and nonassessable.

             We consent to the filing of this opinion letter as Exhibit 5.1 to
the Registration Statement and to the reference to this firm under the caption
"Legal Matters" in the prospectus which is part of the Registration Statement.
In giving this consent, we do not thereby admit that we are within the category
of persons whose consent is required under Section 7 of the Act, the rules and
regulations of the Securities and Exchange Commission promulgated thereunder, or
Item 509 of Regulation S-K.

2. EXCLUSIVE RIGHT TO PROVIDE HSAC SERVICES TO COMMITTED SYSTEMS; ADDITIONAL
COMMITTED SYSTEMS; INSPECTION AND ACCEPTANCE CRITERIA.

         2.1. Exclusive Access. During the Term, HSAC shall have the sole and
exclusive right to access the Committed Systems listed on EXHIBIT A to this
Agreement for purposes of performing the HSAC Services and to perform the HSAC
Services for the Committed Systems, subject to and in accordance with the terms
herein and the Systems Access Agreement. Subject to the procedures set forth in
this Section 2, HSAC shall perform a Full HSAC Services Roll-Out on every such
Committed System within the time frames specified for a particular Committed
System in the Activation Schedule.

         2.2. Designation of Additional Systems. During the Term (and subject to
the procedures set forth in this Section 2), Operator and Potential Operators
shall have the unilateral right, but not the obligation, to designate an
unlimited number of additional Cable Systems as Committed Systems under this
Agreement, and such right shall extend to any and all Cable Systems now owned or
managed or hereafter acquired or managed by Operator or Potential Operator.
Operator and Potential Operators shall exercise their right to designate
additional Cable Systems as Committed Systems hereunder by delivering written
notice of such designation to HSAC (an "Additional System Notice"). Upon HSAC's
receipt of such Additional System Notice, HSAC and the applicable Operator shall
amend this Agreement to add such Cable System(s) to EXHIBIT A, and the Cable
System(s) designated in such Additional System Notice shall automatically become
Committed Systems hereunder. If a Potential Operator designates Committed
Systems hereunder, the parties and such Potential Operators shall amend this
Agreement to include such Potential Operator as an Operator for all purposes
hereunder.

         2.3. Commissioning of RF Plant; System Data Requirements. Within sixty
(60) days of (i) the Effective Date (as to the Committed Systems referenced in
Section 2.1 above), and (ii) HSAC's receipt of an Additional System Notice (as
to the Committed Systems referenced in Section 2.2 above), HSAC shall perform an
engineering inspection of Operator's RF Plant in the applicable Committed
Systems and deliver to Operator, HSAC's recommendations for any upgrades or
repairs (if HSAC fails to deliver such recommendations for any Committed System
within such 60 day period, then such Committed Systems will be deemed to satisfy
the System Data Requirements) which may be necessary for the Committed System to
conform to System Data Requirements ("Attainment Measures"). Operator
acknowledges and agrees that (i) in order for HSAC to deliver HSAC Services to
Data Subscribers, each Committed System must satisfy the System Data
Requirements, (ii) HSAC is not responsible for whether the Committed Systems
satisfy the System Data Requirements, and (iii) Operator shall undertake (or
refuse to take, as the case may be) those Attainment

                                     - 6 -
<PAGE>   7
Measures necessary to cause the Committed System's RF Plant to attain, and
thereafter maintain in conformity with, the System Data Requirements during the
Term of this Agreement. If the Operator declines to effect appropriate
Attainment Measures for any particular Committed System, this Agreement shall
terminate as to such Committed System without liability of any kind to either
Operator or HSAC, and such Committed System shall be removed from EXHIBIT A of
this Agreement. If the Operator agrees to effect the Attainment Measures, the
Activation Schedule shall be amended to establish the milestones for Operator to
bring the Committed Systems into conformity with the System Data Requirements
including a reasonable amount of additional time for HSAC to complete its Full
HSAC Services Roll-Out for such Committed Systems.

         2.4.     Activation Schedule.

                  2.4.1. The Activation Schedule for the initial Committed
Systems as of the Effective Date hereunder shall be as set forth in EXHIBIT A.
Within forty-five (45) days of HSAC's receipt of an Additional System Notice,
Operator and HSAC shall negotiate and agree in good faith upon a feasible,
reasonable "critical path" timelines for each Committed System's Full HSAC
Services Roll-Out, and memorialize such timeline in an Activation Schedule (as
same may be amended from time to time as contemplated in Section 2.3 above to
account for the Operator's taking of Attainment Measures and as the parties may
otherwise agree in writing). The Activation Schedule shall set out
implementation milestones, including, without limitation: (i) that Operator
shall notify HSAC when a particular Committed System conforms (or when the
Operator expects such Committed System to conform if the taking of Attainment
Measures is required) with the System Data Requirements, (ii) the Launch Date,
and (iii) the date when the Full HSAC Services Roll-Out in each Committed System
shall be completed. In the event that the parties cannot agree upon a reasonable
Activation Schedule for any additional Committed Systems designated under
Section 2.2 within forty-five (45) days of HSAC's receipt the applicable
Additional Systems Notice, then the provisions of Section 6.4 of the Systems
Access Agreement shall apply, and HSAC will implement the HSAC Services for such
additional Committed Systems at a rate of eight (8) head-ends per month (such
head-ends to be designated by Operator), with Operators' head-ends receiving
priority for activation over head-ends owned and/or operated by other customers
of HSAC.

                  2.4.2. HSAC will not be deemed in default of a scheduled
Launch Date if (i) a Regional Bell Operating Company ("RBOC") or other telephone
network provider (a "telco") is late in installing a T-1 line or backbone
connection necessary for the HSAC Services following the submission of a
complete order by HSAC to such party before the lead times required by such
party in order to install such T-1 line or backbone connection in sufficient
time to meet the applicable Launch Date, (ii) an equipment vendor (e.g., COM21)
fails to meet its delivery deadlines with respect to the HSAC Network Equipment
or Home Equipment Packages following the submission of a complete order by HSAC
to such party before the lead times required by such party in order to deliver
such equipment in sufficient

                                     - 7 -
<PAGE>   8
time to meet the applicable Launch Date, or (iii) HSAC does not receive any
specialized equipment required to carry the Vulcan Content (as defined in the
Content Agreement), which equipment is otherwise not required in order to
perform the HSAC Services, on a timely basis following the submission of a
complete order by HSAC to the vendor of such equipment before the lead times
required by such vendor in order to deliver such equipment in sufficient time
for HSAC to meet the applicable Launch Date.

3. HSAC OBLIGATIONS AFTER COMMISSIONING. As soon as Operator notifies HSAC that
any head-end in a Committed System conforms to the System Data Requirements,
HSAC agrees that it shall in conformity with the Activation Schedule:

         3.1. install and connect the HSAC Network Equipment (subject to Section
6.2);

         3.2. arrange at its expense for data transport (via telco, wireless,

and provide the HSAC Services for such Committed Systems.

4. UPGRADES. After initial activation of HSAC Services in a Committed System,
the Operator may reasonably request upgrades to the HSAC Network Equipment, and
HSAC shall make such upgrades at its expense within a reasonable time period,
provided that such upgrades are commercially reasonable. HSAC shall also make
substantially the same upgrades to the HSAC Network Equipment that HSAC makes to
substantially similar equipment that HSAC uses to provide HSAC or third party
customers access to the Internet. HSAC will provide Operator with all updates
and upgrades that HSAC develops or uses on any Cable System at the same prices
as such updates and upgrades are provided by HSAC to other customers of HSAC.
Neither party shall unilaterally change HSAC Network Equipment or Operator's RF
Plant in any way that renders a Committed System or the HSAC Services inoperable
without consulting with the other party regarding the allocation of costs
relating to such changes or upgrades.

                                     - 9 -
<PAGE>   10


($150) per Data Subscriber). If HSAC sells equipment compressing any part of the
Home Equipment Package to a Data Subscriber, then HSAC shall pay 50% of the
gross profit (i.e., the gross "retail" sales price (not including applicable
sales taxes) less its direct wholesale cost for such equipment and any other
direct, out-of-pocket sales expense) it receives from such sale. If Operator
sells equipment that is part of the Home Equipment Package, then Operator shall
keep 100% of the Gross Revenues from [ILLEGIBLE]. If HSAC rents any equipment
that is part of the Home Equipment Package to a Data Subscriber, then HSAC shall
be entitled to retain 100% of such rentals up to a maximum of $14.95 per month
per Data Subscriber, and all rentals in excess of such amount will be divided
equally between HSAC and Operators. Nothing in this Section 6.2 shall limit
Operator's ability to charge and retain separate fees for connecting any Cable
Subscriber's or Data Subscriber's home to a Cable System or adding additional
outlets in a Cable Subscriber's or Data Subscriber's home.


7. ALLOCATION OF GENERAL OPERATIONAL RESPONSIBILITIES OF OPERATOR AND HSAC.
During the Term of this Agreement as to each Committed System, the following
provisions shall be applicable:

         7.1. Operator Responsibilities. Operator agrees to maintain its RF
Plants and facilities in the Committed Systems in conformity with industry
standards and the System Data Requirements set forth in EXHIBIT B for the
carriage of HSAC Services throughout the Committed Systems.

         7.2. HSAC Responsibilities. Following the commissioning of each
Committed System, in addition to the obligations set forth in Section 3.1 above,
HSAC agrees that it shall throughout the Term:

                  7.2.1. complete the Full HSAC Services Roll-Out and provide
the HSAC Services for Data Subscribers in the Committed Systems;

                  7.2.2. undertake and ensure that the HSAC Services, all HSAC
Network Equipment, and all software and services related to the HSAC Services
attain and maintain compliance with industry standards and the System Service
Requirements;

                  7.2.3. take all reasonable efforts to ensure that HSAC
Services are received only by Data Subscribers, and to take all reasonable
efforts to prevent unlawful reception, retransmission, or use of the HSAC
Services by any means, whether now known or hereafter devised, without the prior
written authorization of HSAC;

                  7.2.4. following activation of HSAC Services, control the flow
of data that it manages from the Committed Systems to the Internet Portal, and
HSAC shall be responsible for third-party software utilized to perform the HSAC
Services;

                  7.2.5. provide a toll-free telephone number and a Network
Operating Center ("NOC") and Customer Service Call Centers ("Call Center")
staffed 24 hour a day, 7 day a

                                     - 10 -
<PAGE>   11
week basis (including weekends and holidays) via pager, cell phone, or similar
means ("24x7") with telephone support representatives to take calls from Data
Subscribers in the Committed System regarding Service Failures, the
operation/performance of the Home Equipment Package, and the Internet browser
and electronic mail software provided by third parties. HSAC shall answer all
such Data Subscriber calls with a greeting mutually agreed upon by the parties.
(Operator shall similarly provide HSAC with 24 x 7 "customer service response"
for the Committed System/RF portion of the HSAC Services.) HSAC shall make its
engineers and technicians available as needed to provide technical support and
to serve as liaisons between or among the Data Subscribers, Operator, and HSAC.

         7.3.     Certain Joint Responsibilities.  Operators and HSAC agree:

                  7.3.1. that if either party becomes aware that any
unauthorized party is receiving or transmitting any part of the HSAC Services,
then such party shall notify the other party in writing of the name and address
of such party if and when the first party actually knows the name and address of
such third party;

                  7.3.2. to exercise their commercially reasonable efforts to
maintain the secrecy of (and occasionally rotate) their software passwords, and
notify the other if they become aware that their system passwords may be or have
become compromised;

                  7.3.3. to comply with all applicable local, state and federal
laws, rules, regulation and franchises in all material respects;

                  7.3.4. to notify the other's NOC and Call Center promptly of
any material outages, interruptions, or degradation of service in either
Operator's RF Plant or the data portion of the HSAC Services (a "Service
Failure") of which they become aware from any source (i.e., a "Notice"). To the
extent a Service Failure is traceable to an RF Plant defect or malfunction
(whether or not due to Force Majeure), Operator shall provide technical
personnel within 4 hours (or on a commercially reasonable basis) of such Notice
to respond to such Service Failure and shall repair or replace any
malfunctioning equipment as soon as commercially practicable. To the extent the
Service Failure is traceable to HSAC Network Equipment or a data stream
malfunction, HSAC shall correct the Service Failure within 4 hours (or on a
reasonable commercial efforts basis) of such Notice or replace any
malfunctioning equipment as soon as commercially practicable; and

                  7.3.5. to cooperate and work together diligently to respond to
all Service Failures, and coordinate the scheduling of maintenance that might
interfere with the HSAC Services, provided that HSAC shall be responsible for
all NOC and customer service functions and requirements not related to the RF
Plant of Operator's Cable Systems. Both parties acknowledge that Service
Failure-related downtime, incorrect or inaccurate Data Subscriber invoicing, and
infrastructure problems shall be given highest priority attention at all times.
Operator and HSAC shall each have access to the other's NOC and Call Center on a

                                     - 11 -
<PAGE>   12
24x7 basis for the purpose of troubleshooting Service Failures pursuant to
agreed-upon Escalation Procedures, which are attached hereto as EXHIBIT C.

         7.4. Billing; End User Agreement. The procedure for processing
subscriptions for HSAC Services, the invoicing of Data Subscribers, and the
sharing of Gross Revenues shall be as set forth on EXHIBIT D attached hereto.
HSAC shall also distribute to and require Data Subscribers to sign an "End
User/Services Agreement" substantially in the form of EXHIBIT E attached hereto
which describes the limits placed on Data Subscribers' rights; provided, that
HSAC shall be under no obligation to enforce the terms of such End User/Services
Agreement.

         7.5. Data Subscriber Cancellation/Disconnect. In the event a Data
Subscriber terminates cable TV services with Operator and also cancels its
subscription to HSAC Services at the same time, Operator shall notify HSAC of
same and use its commercially reasonable efforts to recover and store (but does
not guarantee that it shall be able to recover), any rented Home Equipment
Package (except for the Ethernet card inside the customer's PC) for and on
behalf of HSAC. HSAC and Operator agree that in the event a Data Subscriber
cancels only its subscription to HSAC Services, HSAC shall likewise notify
Operator and be solely responsible for recovering any rented Home Equipment
Package.

         7.6.     Promotional and Build-Out Activities.

                  7.6.1. The parties shall cooperate reasonably with one another
regarding the marketing and promotion of HSAC Services to Cable Subscribers with
the aim of maximizing the number of Data Subscribers to the extent economically
feasible. Such cooperation shall include (i) at Operator's discretion,
installation of a "drop/install" at Operator's reasonable expense (may be passed
on to the Cable Subscriber) to any Home Passed, (ii) at HSAC's discretion,
Operator's installation of a "drop/install" for any commercial sites in a
Committed System for which HSAC will pay Operator's reasonable expenses (that
may be passed on to the commercial customer), and (iii) reasonable provision of
free advertising for the HSAC Services in the form of "ad avails" (i.e.,
advertising space which is not sold or committed to third parties that Operator
designates at its sole discretion as being available for advertising for HSAC
Services, "Charter Pipeline," "Marcus OnLine", "Charter Communications", "Marcus
Cable", or other brands as Operator may designate at its sole discretion) on
Operator's cable TV system, space in bills, statement messaging, and space in
installation packs. HSAC shall be responsible for the incremental expenses (if
any) associated with Operator's handling bill stuffers, space in bills,
statement messaging, and installation packs that are implemented at HSAC's
request. In addition, HSAC shall reimburse Operator for forty thousand dollars
($40,000) dollars annually in the aggregate expended by Operator for television
advertising to promote the Operator's Internet access brands under which HSAC
Services are provided.

                  7.6.2. All marketing and promotional materials, and any
materials that have an Operator owned or controlled trade or service mark on
them, will comply with the Quality

                                     - 12 -
<PAGE>   13
Controls specified on EXHIBIT F hereto. Before any such materials prepared by
HSAC are used, HSAC will transmit a copy to Operator, and Operator will have
fifteen (15) days in which to reasonably reject such materials or to request
changes be made to such materials. If Operator does not respond to HSAC within
such fifteen (15) day period, such materials will be deemed approved for
distribution. All marketing and promotional materials will comply with the
branding provisions set forth in Section 7.6.5 below and shall be of a standard
of quality comparable to marketing and promotional materials prepared and
distributed by Operator. Operator grants to HSAC a worldwide, non-exclusive
royalty-free licensee to use and reproduce Operator's trademarks, service marks,
and brands and to distribute any marketing and promotional materials supplied to
HSAC by Operator (in Operator's sole discretion) for purposes of advertising and
marketing the HSAC Services in accordance with the terms and conditions hereof.

                  7.6.3. HSAC's marketing team will meet quarterly with each of
Operator's regional marketing teams and jointly review marketing plans,
strategy, and materials for each Committed System to assure acceptable quality
standards in accordance with the procedures in EXHIBIT I and Charter's current
Charter Pipeline Branding Guidelines. By October 31 of each calendar year during
the Term, HSAC shall also provide Operator with a copy of HSAC's marketing plan
(which when implemented shall substantially conform to Operator's approved
annual marketing plans for the following year), which Operator may approve or
reject in its reasonable discretion. The parties agree to confer and work
together to effect any appropriate revisions to HSAC's annual marketing plans
and materials, provided that Operator shall not be entitled to unilaterally
dictate HSAC's levels of marketing expenditures or HSAC's creative decisions or
choice or relative emphasis across various marketing channels, so long as the
foregoing shall not result in any detriment to or denigration of Operator's
brand image.

                  7.6.4. Subject to Section 7.8 below, Operator shall provide
HSAC access (both print copy and electronically at HSAC's expense) to its
Customer Lists and other customer databases on a confidential basis solely for
the purpose of developing and implementing HSAC's marketing plans, as well as
providing "On-Line Help-Desk" modem configuration support, Data Subscriber
sign-up, and ongoing customer service.

                  7.6.5.   Branding

                           (a) Without limiting HSAC's obligations under the
         Content Agreement, the parties agree that all HSAC Services (and all
         other Internet access and related services performed by HSAC within any
         Committed Systems' areas) shall be marketed, deployed, and supported in
         the Committed Systems only under the trademarks "Charter Pipeline,"
         "Marcus OnLine", "Charter Communications", "Marcus Cable" or other
         brands, service marks, and trademarks as Operator may designate.
         Operator shall be responsible for registering such brands, service
         marks, and trademarks and obtaining a matching or closely related
         domain name. Any such domain names shall be owned by the relevant
         Operator, or if they are temporarily

                                     - 13 -
<PAGE>   14
         owned by HSAC, HSAC shall take all steps necessary promptly to transfer
         and assign such domain names to the relevant Operator.

                           (b) Subject to reasonable Operator oversight, HSAC
         shall produce and distribute all marketing materials and execute all
         marketing plans applicable to the HSAC Services. All marketing and
         promotional materials and any materials that have an Operator owned or
         controlled trademark on it shall comply with the Quality Controls
         specified in EXHIBIT F and before any such materials are used, a copy
         shall be sent to Operator, who shall have fifteen (15) days in which to
         reject such materials or to request changes be made to such materials.
         If Operator has not responded to HSAC within the fifteen (15) day
         period, such materials shall be deemed approved for distribution.

                           (c) Operator shall contribute reasonable ad avails
         (i.e., advertising space which is not sold or committed to third
         parties that Operator designates at its sole discretion as being
         available for advertising for HSAC Services, "Charter Pipeline,"
         "Marcus OnLine", "Charter Communications", "Marcus Cable", or other
         brands as Operator may designate at its sole discretion), space in
         bills, bill stuffers, statement messaging, and space in cable
         installation packs to promote the sales of subscriptions to HSAC
         Services to Cable Subscribers.

                           (d) Subject to all of the terms and conditions of
         this Agreement, if a Committed System is withdrawn from this Agreement,
         then HSAC shall be permitted to continue to use those trademarks,
         service marks, and brands owned by Operator that HSAC had been using
         for dial up Internet access services provided in such Committed System
         immediately before such Committed System was withdrawn from this
         Agreement for a six (6) month transition period but only for the dial
         up Internet access services provided within such Committed System's
         area.

                  7.6.6. Operator shall not be obligated to expand or upgrade
its RF Plants in the Committed Systems after a Launch Date. However, the parties
agree to jointly review and evaluate periodically the economic feasibility of
expanding or upgrading such RF Plants in order to increase the number of Homes
Passed and/or commercial Data Subscribers and to determine how such costs shall
be shared.

         7.7. Complimentary and Discounted Employee Accounts. HSAC shall at
Operator's direction provide to Homes Passed in each Committed System
complimentary HSAC Services accounts (except that, unless expressly set forth
below to the contrary, such recipients of complimentary service must pay for
their own Home Equipment Packages as would any other Data Subscriber) as
follows:

                  7.7.1. on a complimentary basis, up to five (5) transferable
accounts as designated by Operator;

                                     - 14 -
<PAGE>   15

                  7.7.2. on a complimentary basis, the greater of five (5)
additional government/"community service" accounts per Committed System or one
per franchise in each Committed System;

                  7.7.3. on a complimentary basis, the number of additional
accounts (complete with the modem/Home Equipment Package in this case only)
necessary for use within Operator's office(s) to support the HSAC Services (via
multiple modems or single-modem with hub/proxy server distribution as the
parties may agree);

                  7.7.4. such additional complimentary accounts as HSAC in its
sole discretion shall determine; and

                  7.7.5. on a fifty percent (50%) discount basis, additional
accounts for Operator's employees at their residences within a Committed System.

         7.8 Ownership of Customer Information. Notwithstanding anything to the
contrary set forth in this Agreement, the Data Subscribers and any Customer
Lists shall be deemed to be owned solely by, and shall be solely the property of
Operator, and all dial-up subscribers to the HSAC Services and related customer
lists shall be deemed to be owned solely by, and shall be solely the property
of, HSAC.


8. ASSIGNMENT OF DOMAIN NAMES. HSAC shall be responsible for assigning all
e-mail and Web Site addresses to Data Subscribers. All e-mail and Web Site
addresses for Data Subscribers shall use domain names that are registered in
Operator's name and are pre-approved by Operator in writing. HSAC shall keep an
updated list of such e-mail and Web Site addresses and shall supply Operator
with an electronic copy of such list whenever Operator requests.


9. ENCRYPTION. HSAC may at its option make available security and encryption
equipment and/or software to Data Subscribers at no additional charge to
Operator; provided, that HSAC is not obligated to do so, nor shall Operator be
liable or responsible in any way for the installation and performance of such
equipment or software. HSAC represents and warrants that any such security and
encryption equipment and software will not interfere with the operation of the
Committed Systems in any way.

10.      CONFIDENTIAL INFORMATION.

         10.1. Confidentiality. Each party agrees that it shall not, during or
for a period of five (5) years after the Term of this Agreement, permit the
duplication, use, or disclosure of any Confidential Information to any person
(other than an employee, agent, or representative of the other party who must
have such information for the performance of its obligation hereunder), unless
such duplication, use or disclosure is specifically authorized by the other
party in writing. Each party shall (i) not disclose any Confidential Information
to any third person without the express written consent of the other party; (ii)
not use, directly, indirectly, or in concert with any other person, any
Confidential Information for any purpose other than



                                     - 15 -
<PAGE>   16
the performance of their obligations under this Agreement; (iii) use reasonable
diligence, and in no event less than that degree of care which such party uses
in respect to its own Confidential Information of like nature, to prevent the
unauthorized disclosure or reproduction of such information. Without limiting
the generality of the foregoing, to the extent that this Agreement permits the
copying of Confidential Information, all such copies shall bear the same
confidentiality notices, legends, and intellectual property rights designations
that appear in the original versions.

         10.2. Exceptions. The confidentiality obligations set forth in Section
10.1 shall not be applicable to Confidential Information which is: (i) in the
public domain; (ii) known to the recipient party as of the date of this
Agreement as indicated by the recipient's written records, unless the recipient
party agreed to keep such information in confidence at the time of its receipt;
(iii) properly obtained hereafter from a source who is not under an obligation
of confidentiality with respect to such information; (iv) can be shown to have
been independently developed by the receiving party through persons who have not
had, either directly or indirectly, access or knowledge of such Confidential
Information; or (v) obligated to be produced by law, provided that any party
that is so ordered to produce Confidential Information shall give notice thereof
to the other party and cooperate reasonably with any attempt by the notified
party to enjoin its disclosure.

         10.3. Destruction of Data. Apart from HSAC's obligations to Operator
under this Section 10 concerning confidentiality, HSAC shall have no obligation
to delete or destroy Operator's information, including Operator's Customer Lists
or other Data Subscriber listings, from its computer systems or backup and
archival libraries until such time as HSAC's regular procedures for elimination
of such data would normally delete or destroy such information. Following a Data
Subscriber disconnect, Operator may require the elimination of its data
maintained within HSAC's backup and archival libraries prior to the time the
data would normally be deleted or destroyed by HSAC, and Operator shall pay for
reasonable expenses associated with the early deletion or destruction of all
such data.

11.      OWNERSHIP OF MARKS.

         11.1. HSAC Marks. Operator acknowledges that the names and marks "HSA,"
"HSAC," "HSA Network," "High Speed Access Network," "HSA Data Network," "Darwin
Networks," "CATV.net" and other HSAC logos, program names, trademarks, service
marks, programs, manuals, documentation, and other support materials covered by
this Agreement or otherwise used in connection with the HSAC Service, are the
exclusive property of HSAC. Operator has not and shall not acquire any
proprietary rights thereto by reason of this Agreement, and Operator shall have
no rights to use such names, marks, logos, variations or titles except at the
times and in a manner expressly approved by HSAC. Operator shall not publish or
disseminate any material that violates any restriction imposed by HSAC.

         11.2. Operator's Marks. Conversely, HSAC acknowledges that the names
and marks "Charter," "Charter Communications," "Charter Pipeline," "Charter
Mail," "Marcus

                                     - 16 -
<PAGE>   17
OnLine," and other Operator logos, program names, trademarks, service marks,
programs, manuals, documentation, host names, domain names, and other support
materials under which the HSAC Services shall be rolled-out under this Agreement
or otherwise used in connection with the HSAC Services, are the exclusive
property of Operator. HSAC has not and shall not acquire any proprietary rights
thereto by reason of this Agreement other than its contract rights hereunder,
and HSAC shall have no rights to use such names, marks, logos, variations or
titles except at the times and in a manner expressly approved by Operator. HSAC
shall not publish or disseminate any material that violates any restriction
imposed by Operator.

12. REPRODUCTION OF MANUALS AND DOCUMENTATION. Subject to the provisions of
Sections 10 and 11.1, Operator shall have the right, at no additional charge, to
reproduce solely for its internal use, all manuals and documentation furnished
by HSAC relating to the HSAC Services, regardless of whether such manual or
documentation is copyrighted by HSAC. All copies of manuals or documentation
made by Operator shall include any proprietary notice or stamp that has been
affixed by HSAC.

13.      REPRESENTATIONS AND WARRANTIES.

         13.1. HSAC hereby represents and warrants to Operator as follows:

                  13.1.1. HSAC is a corporation duly organized, validly existing
and in good standing under the laws of the state of Delaware, and is duly
qualified to do business as a foreign corporation in all jurisdictions in which
it conducts its business.

                  13.1.2. HSAC's execution, delivery, and performance of this
Agreement and each of the Other Agreements have been duly authorized by all
requisite corporate action, and this Agreement and each of the Other Agreements
constitutes a legally valid and binding obligation of HSAC enforceable in
accordance with their terms, except as may be affected by laws relating to
bankruptcy or insolvency or the application by a court of equitable principles.

                  13.1.3. HSAC's execution, delivery, and performance of this
Agreement and each of the Other Agreements shall not violate, conflict with
and/or result in a breach or default under HSAC's certificate of incorporation,
bylaws or other charter documents, or any judgment, award, decree, agreement or
other instrument to which HSAC is a party.

                  13.1.4. No approval, authorization, consent, or order or
filing with any court, or governmental or administrative agency or any third
party is required in order for HSAC to enter into, deliver, and perform this
Agreement, each of the Other Agreements, and the transactions contemplated
herein and therein.

                  13.1.5. HSAC either owns or has properly licensed all rights
under patent, copyright, trademark, trade secret, and other domestic and foreign
intellectual property laws (collectively, "Intellectual Property Laws") that are
necessary or required to perform the Full HSAC Services Roll-Out, the HSAC
Services, and the other services to be performed by



                                     - 17 -
<PAGE>   18

HSAC hereunder and under the Network Agreements, including, without limitation,
all rights under Intellectual Property Laws relating to any equipment
(including, without limitation, the HSAC Network Equipment), software or Content
that HSAC shall use or shall provide in connection with the Full HSAC Services
Roll-Out, the HSAC Services, and the other services to be performed by HSAC
hereunder and under the Network Agreements. HSAC's provision and/or operation of
the Full HSAC Services Roll-Out, the HSAC Services, and the other services to be
performed by HSAC hereunder and under the Network Agreements shall not violate
or infringe any Intellectual Property Laws or violate or infringe any rights of
third parties.

                  13.1.6. To the best of its knowledge, HSAC has taken all
actions necessary and appropriate to assure that there shall be no material
adverse change to its business or electronic systems or material interruptions
in the operation and delivery of HSAC Service as provided in this Agreement
(aside from normal data packet delays, distortions, and losses (i) on the
Internet backbone, (ii) during transport to the Internet Backbone on
telecommunication lines leased from a third party, (iii) or during transport
from the customer to HSAC over a coaxial cable or fiber optic line) by reason of
the advent of the year 2000, including, without limitation, that all its
computer-based systems, embedded microchips and other data processing
capabilities have been designed or modified and fully tested in such a manner
that such computer-based systems, embedded microchips and other data processing
capabilities will not generate any invalid and/or incorrect date-related results
or cause any of the problems commonly referred to as "Year 2000 problems" and
will, without interruption or manual intervention, continue to operate
consistently, predictably and accurately and in accordance with all of the
requirements of this Agreement, including without limitation, meeting all
specifications and/or functionality and performance requirements, when used
during any year prior to, during or after the calendar year 2000. HSAC does not
warrant that interruptions in HSAC Service will not occur due to the network or
systems failures of other parties, including utilities and phone services,
caused by "Year 2000 problems."

         13.2. Each Operator hereby represents and warrants, severally, but not
jointly, and only as to itself, to HSAC as follows:

                  13.2.1. It is a corporation duly organized, validly existing,
and in good standing under the laws of its jurisdiction of incorporation and is
duly qualified to do business as a foreign corporation in all jurisdictions in
which it conducts its business.

                  13.2.2. Their execution, delivery, and performance of this
Agreement and each of the Other Agreements have been duly authorized by all
requisite corporate action, and this Agreement and each of the Other Agreements
constitutes a legally valid and binding obligation of each of them enforceable
in accordance with their terms, except as may be affected by laws relating to
bankruptcy or insolvency or the application by a court of equitable principles.



                                     - 18 -
<PAGE>   19



                  13.2.3. Their execution, delivery, and performance of this
Agreement and each of the Other Agreements shall not violate, conflict with
and/or result in a breach or default under their respective certificates of
incorporation, bylaws or other charter documents, or any judgment, award,
decree, agreement or other instrument to which either of them is a party.

                  13.2.4. No approval, authorization, consent, or order or
filing with any court, or governmental or administrative agency or any third
party is required in order for it to enter into, deliver, and perform this
Agreement, each of the Other Agreements and the transactions contemplated herein
and therein.

                  13.2.5. The franchise agreements with the various franchising
authorities with jurisdiction over the Committed Systems do not and will not
prohibit Operator from offering the HSAC Services directly or through HSAC under
this Agreement. Operator shall bear all costs associated with obtaining any such
"data over cable" franchise rights and authorizations (if so needed), pay any
franchise taxes related or applicable thereto, and indemnify HSAC with respect
to any such costs or taxes, whether or not retroactively assessed.

                  13.2.6. Operator either owns or has properly licensed all
rights under Intellectual Property Laws that are necessary or required to
utilize Operator's trademarks, service marks, or brands and the marketing and
promotional materials licensed to HSAC hereunder, and HSAC use of the foregoing
shall not violate or infringe any Intellectual Property Laws or intellectual
property rights of third parties.

                  13.2.7. To the best of its knowledge, it has taken all actions
necessary and appropriate to assure that there shall be no material adverse
change to its business or electronic systems or material interruptions in the
operation and delivery of HSAC Service as provided in this Agreement (aside from
normal data packet delays, distortions, and losses (i) on the Internet backbone,
(ii) during transport to the Internet Backbone on telecommunication lines leased
from a third party, (iii) or during transport from the customer to HSAC over a
coaxial cable or fiber optic line) by reason of the advent of the year 2000,
including, without limitation, that all its computer-based systems, embedded
microchips and other data processing capabilities have been designed or modified
and fully tested in such a manner that such computer-based systems, embedded
microchips and other data processing capabilities will not generate any invalid
and/or incorrect date-related results or cause any of the problems commonly
referred to as "Year 2000 problems" and will, without interruption or manual
intervention, continue to operate consistently, predictably and accurately and
in accordance with all of the requirements of this Agreement, including without
limitation, meeting all specifications and/or functionality and performance
requirements, when used during any year prior to, during or after the calendar
year 2000. Operator does not warrant that interruptions in HSAC Service will not
occur due to the network or systems failures of other parties, including
utilities and phone services, caused by "Year 2000 problems."

14.      INDEMNITY.

         14.1. HSAC will indemnify, defend, and hold harmless each Operator and
its respective affiliates, agents, successors, assigns, representatives,
officers, and directors from and against any liabilities, lawsuits, penalties,
claims, demands, awards, judgments, settlements, costs, and expenses (including,
without limitation, actual reasonable attorneys' fees and expenses on account
thereof) that arise or result from: (i) the breach by HSAC of any of its
representations, warranties, or covenants hereunder, (ii) HSAC's management,
operation, control or provision of the HSAC Services, or (iii) any violations of
any United States export control restrictions relating to the encryption
equipment and/or software made available by HSAC to Data Subscribers under
Section 9 above, including, without limitation, in any such case any
liabilities, lawsuits, penalties, or claims related to defamation, infringement,
criminal activities, and fraud, except to the extent that any such liabilities,
lawsuits, penalties, claims, demands, awards, judgments, settlements, costs or
expenses arise from such Operator's operation, management, and maintenance of
its RF Plant.

         14.2. Each Operator will severally, but not jointly, and only with
respect to its own acts or omissions, indemnify, defend, and hold harmless HSAC
and its affiliates, agents, successors, assigns, representatives, officers, and
directors from and against any liabilities, lawsuits, penalties, claims,
demands, awards, judgments, settlements, costs, and expenses (including, without
limitation, reasonable attorneys' fees and expenses on account thereof) that
arise or result from: (i) the breach by such Operator of any of its
representations, warranties or covenants hereunder, or (ii) such Operator's
operation, management, and maintenance of such Operator's RF Plant, including,
without limitation, in any such case, any liabilities, lawsuits, penalties, or
claims related to defamation, infringement, criminal activities, and fraud,
except to the extent that any such liabilities, lawsuits, penalties, claims,
demands, awards, judgments, settlements, costs or expenses arise from HSAC's
management, operation, control or provision of the HSAC Services.

         14.3. HSAC agrees to indemnify, defend, and hold harmless each Operator
and its respective affiliates, agents, successors, assigns, representatives,
officers, and directors, and each Operator agrees severally, but not jointly,
and only with respect to its acts or omissions, to indemnify, defend, and hold
harmless HSAC and its affiliates, agents, successors, assigns, representatives,
officers, and directors, from and against any liabilities, lawsuits, penalties,
claims, demands, awards, judgments, settlements, costs and expenses (including,
without limitation, reasonable attorneys' fees and expenses on account thereof)
that may be made for injuries, including death to persons, resulting from the
indemnifying party's negligent or willful acts or omissions or those of persons
employed by the indemnifying party, its agents, or subcontractors. Each Operator
and HSAC respectively agree to notify the other parties promptly of any written
claims or demands against the indemnified party for which the indemnifying party
is deemed responsible hereunder; provided, that, any failure to so notify shall
not affect the substantive rights hereunder.

15.      LIMITATION OF LIABILITY, INSURANCE.



                                     - 20 -
<PAGE>   21



         15.1. Limitation of Liability. EXCEPT FOR THE INDEMNIFICATION
OBLIGATIONS DETAILED IN SECTION 14 ABOVE, IN NO EVENT WILL EITHER PARTY HERETO
BE LIABLE TO THE OTHER PARTY FOR ANY INDIRECT, INCIDENTAL, OR CONSEQUENTIAL
DAMAGES (EVEN IF THAT PARTY HAD BEEN ADVISED OF THE POSSIBILITY OF SUCH
DAMAGES), ARISING FROM OR RELATED TO A BREACH OF THIS AGREEMENT, INCLUDING
WITHOUT LIMITATION LOSS OF REVENUE OR ANTICIPATED PROFITS OR LOST BUSINESS.

         15.2. Insurance. At all times during the Term, HSAC shall maintain: (i)
appropriate policies of general liability, casualty, and business interruption
or disruption insurance, each with aggregate coverage of at least two million
dollars ($2,000,000) with commercially reasonable deductibles; (ii) appropriate
workers compensation insurance to cover HSAC's employees against injury to
themselves or others and casualty accidents while performing HSAC Services; and
(iii) appropriate insurance policies with at least two million dollars
($2,000,000) of coverage per incident with commercially reasonable deductibles
covering against claims for intellectual property infringement. All such HSAC
insurance policies shall name Operator as an additional insured party.

         15.3. Specific Performance. HSAC and Operator each acknowledges that
the rights granted, and services to be provided to each other hereunder are of a
special, unique, unusual, extraordinary, and intellectual character, giving them
peculiar value, the loss of which cannot be reasonably or adequately compensated
in damages, and that an actual or threatened material breach by either party
hereunder would cause the other party irreparable injury and damage. Subject to
Section 9.2.2 off the Content Agreement, each party agrees that, if it commits
or is about to commit a material breach of this Agreement, the other party will
be entitled to injunctive or other equitable relief as a remedy for any such
actual or threatened material breach, without the requirement to post any bond
or other security therefor.

16. TERM OF AGREEMENT. The term ("Term") of this Agreement shall commence on the
Effective Date, and as to a particular Committed System, continue for a term of
five (5) years thereafter from the Launch Date for each such Committed System
(the "Initial Term"). Following such Initial Term, this Agreement shall
automatically renew itself on a year-to-year basis (a "Renewal Term") unless
terminated by notice from either party at least three (3) months prior to the
expiration of the Initial Term or any such Renewal Term.

17.      [Intentionally Deleted]

18.      TERMINATION

         18.1. Operator Remedies. In addition to all of Operator's other rights
and remedies at law or equity, Operator has the right to (i) terminate this
Agreement, (ii) renegotiate this Agreement, (iii) remove a particular Committed
System from this Agreement, or (iv) retract HSAC's exclusive rights as to a
particular Committed System, if there has been a Termination Event as set forth
in Section 18.3 hereof. Operator's selection of any one of these remedies

                                     - 21 -
<PAGE>   22
shall not preclude Operator from selecting any other of such remedies for the
same or other Termination Event. Except as set forth in Sections 18.6 and 19
below, in the event that a Termination Event occurs which is limited to a
particular Committed System, Operator may exercise the forgoing rights only with
respect to the Committed System in question and not this entire Agreement.

         18.2. Actions upon Termination. Except as set forth in Section 18.4 to
the contrary, upon any termination or cancellation of this Agreement as to a
particular Committed System for any reason whatsoever: (i) such Committed System
shall be removed from EXHIBIT A and from this Agreement, (ii) Operator shall
purchase from HSAC at book value (based on straight line depreciation) any
ownership rights that HSAC has in the HSAC Network Equipment, Home Equipment
Package, or any other equipment or software owned by HSAC that is committed to
such Committed System; (iii) HSAC shall comply with the Conversion Requirements
with respect to such Committed System; and (iv) HSAC shall transfer to Operator
all Confidential Information, Customer Lists, and any data related to or about
the Data Subscribers relating to the applicable Committed Systems.

         18.3. Termination Events. The following shall be deemed "Termination
Events:"

                  18.3.1. HSAC fails to meet Launch Date applicable to a
particular Committed System;

                  18.3.2. HSAC fails at any time to comply with the System
Service Requirements in any material respect and has not cured such lack of
compliance to Operator's reasonable satisfaction within sixty (60) after
Operator has provided HSAC with written notice of such non-compliance. Operator
shall have the right to at least once every three (3) months to reasonably audit
or observe HSAC's operations in order to determine if HSAC is complying with the
System Service Requirements;

                  18.3.3. There is a failure of the HSAC Services and/or the
HSAC Network Equipment such that the HSAC Services are not available to a
majority of Data Subscribers in a Committed System in the same manner as such
HSAC Services are normally available to such Data Subscribers, which failure is
not cured or repaired within thirty (30) days after Operator gives HSAC written
notice thereof;

                  18.3.4. HSAC becomes insolvent, or a petition under any
bankruptcy act shall be filed by or against HSAC (which petition shall not have
been dismissed within thirty (30) days thereafter), or HSAC executes an
assignment for the benefit of creditors, or a receiver is appointed for HSAC or
its assets, or HSAC takes advantage of any insolvency or any like statute;

                  18.3.5. HSAC fails to upgrade or replace any equipment or
software used in relationship with the HSAC Services such that such equipment no
longer complies with the

                                     - 22 -
<PAGE>   23
vendor's standards and/or industry standards for such equipment, and such
failure is not cured within thirty (30) days after Operator gives written notice
thereof to HSAC;

                  18.3.6. HSAC shall fail to pay to Operator any and all sums
payable to Operator as and when due hereunder within thirty (30) days after
Operator gives HSAC written notice of such failure;

                  18.3.7. HSAC shall fail to carry, distribute and support the
Vulcan Content (as defined in the Content Agreement) on an exclusive basis for
all Cable Systems and other HSAC customers utilizing the HSAC Services in
accordance with the terms of the Content Agreement, HSAC shall carry any
Competing Content (as defined in the Content Agreement) in violation of the
Content Agreement, or HSAC shall breach the provisions of Section 6.3 of the
Content Agreement; and


                  18.3.8. Operator certifies by written notice to HSAC that
HSAC failed to achieve the Minimum Penetration Rate within eighteen (18) months
after the Launch Date applicable to a Committed System.


         18.4. Termination other than for a Termination Event. In addition to
Operators other rights and remedies hereunder, Operator shall have the right at
any time to withdraw any Committed System or terminate HSAC's exclusive rights
to provide HSAC Services with respect to any such Committed Systems for any
reason not covered in Sections 18.3, 18.6 and/or 19. If Operator does so, then
such Committed System shall be withdrawn from this Agreement, provided that (i)
Operator has provided ninety (90) days prior written notice, (ii) Operator pays
to HSAC the Termination Fee, (iii) Operator shall purchase from HSAC at book
value (based on straight-line depreciation) any ownership rights that HSAC has
in the HSAC Network Equipment and Home Equipment Package related to such
Committed System, and (iv) if such termination occurs within twelve (12) months
after the Launch Date with respect to a Committed System, Operator shall
reimburse HSAC for HSAC's actual, out-of-pocket marketing expenses paid by HSAC
with respect to such Committed System prior to date of termination.
Notwithstanding the foregoing, if Operator's withdrawal of a Committed System
from this Agreement under this Section 18.4 occurs as a result of Operator's
sale or other disposition of such Committed System, and the successor MSO or
other successor owner or operator of such Committed System assumes Operator's
obligations hereunder with respect to such Committed System, then Operator shall
not be obligated to comply with the provisions of subsections 18.4(ii), (iii)
and (iv) above in connection with such termination.

         18.5. Replacement of Committed Systems. If upon the removal of a
Committed System from this Agreement for any reason other than termination or
expiration of this Agreement, the aggregate number of Homes Passed in all
Committed Systems hereunder falls below 750,000, then Operators will designate
additional Cable Systems as Committed Systems hereunder such that the total
number of Homes Passed in all Committed Systems under this Agreement is not less
than 750,000.


                                     - 23 -
<PAGE>   24

         18.6. Termination for Repeated Withdrawal of Committed Systems. In the
event that Operator withdraws from this Agreement pursuant to Section 18.1 above
(not including Committed Systems withdrawn pursuant to Section 18.4 above) a
number of Committed Systems equal to or greater than 50% of the total number of
Committed Systems initially included in Exhibit A to this Agreement as of the
Effective Date, then Operator shall have the right to terminate this Agreement
upon thirty (30) days prior written notice to HSAC, without any further
liability or obligation to HSAC.

19. EXCLUSIVITY TERMINATION. In addition to those reasons permitted elsewhere in
this Agreement, Operator may also terminate HSAC's exclusive rights under
Section 2.1 hereof if it is reasonably necessary to comply with any statutes,
regulations, or court orders.

20. INDEPENDENT CONTRACTORS. All work performed by HSAC in connection with the
HSAC Service described in this Agreement shall be performed by HSAC as an
independent contractor and not as the agent, employee, joint venture or partner
of Operator. All persons furnished by HSAC shall be for all purposes solely
HSAC's employees or agents and shall not be deemed to be employees of Operator
for any purpose whatsoever. HSAC shall furnish, employ, and have exclusive
control of all persons to be engaged in performing services under this Agreement
and shall prescribe and control the means and methods of performing such
maintenance services by providing adequate and proper supervision. Nothing
contained herein shall be deemed to create a relationship of joint venture,
associates, principal and agent or partnership between the parties hereto and
neither party shall hold itself out to the contrary. Each party is acting as
principal hereunder.

21. FORCE MAJEURE. Neither party shall be responsible for any Service Failure or
delay or failure in performance of any part of this Agreement to the extent that
such delay or failure is caused by fire, flood, explosion, war, lightning,
embargo, government requirement, riots or civil commotion, acts of civil or
military authority, embargoes, strikes, acts of God, power surges, acts or
omissions of carriers/utilities, or other causes or contingencies beyond its
reasonable control (a "Force Majeure"); provided, that (i) neither party shall
be relieved under this Section 21 from its obligations under Section 7 hereof
with respect to timely repairs of Service Failures caused by such Force Majeure,
and (ii) HSAC has complied with the manufacturers' or vendors' suggested
maintenance for any equipment used in providing the HSAC Services to the extent
such maintenance would have reduced the likelihood of or damage caused by any
Force Majeure. If any such event of Force Majeure occurs and such event
continues for ninety (90) days or more, the party delayed or unable to perform
shall give immediate notice to the other party, and the party affected by the
other's delay or inability to perform may elect to suspend performance of its
allocable portions or duties with respect to the HSAC Services for the duration
of the condition. The affected party may resume performance of its duties once
the condition ceases, and the period of this Agreement shall be deemed extended
for such affected Committed System up to the length of time the condition
endured.

                                     - 24 -
<PAGE>   25
22. ASSIGNMENT. HSAC shall not have the right to assign this Agreement to any
person or entity without the prior written consent of Operators, except that
HSAC may without Operator's consent assign its rights, but not its obligations,
to a subsidiary of HSAC, provided, that, no such assignment will relieve HSAC of
liability for its obligations hereunder. Operators may assign this Agreement to
any person or entity, and this Agreement shall be binding and inure to the
benefit of their successors and assigns. Each party shall be permitted to assign
this Agreement and grant a security interest in its contract rights and
tangible/intangible property interests (including the HSAC Network Equipment and
Home Equipment Packages) arising under this Agreement for purposes of securing
financing from its commercial lender(s). However, as a condition to doing so,
HSAC shall be obligated to obtain non-disturbance agreements in form and
substance satisfactory to Operators from each such lender under which such
lender agrees that, notwithstanding such lender's exercise of its rights as a
secured creditor, such lender and its assigns shall not disturb, affect or
interfere with HSAC's provision of the HSAC Services hereunder. All assignments
in contravention of this Section 22 shall be null and void and of no force or
effect. Either party shall provide the other party with thirty (30) days prior
written notice of any permitted assignment hereunder.

23. AMENDMENTS, MODIFICATIONS, OR SUPPLEMENTS. Amendments, modifications, or
supplements to this Agreement shall be permitted, provided all such changes
shall be in writing signed by the authorized representatives of both parties
unless otherwise expressly permitted in this Agreement, and all such changes
shall reference this Agreement and identify the specific articles or Sections of
this Agreement that is amended, modified, or supplemented.

24. NOTICES. All notices, demands, or other communications herein provided to be
given or that may be given by any party to the other shall be deemed to have
been duly given when made in writing and delivered in person, or upon receipt,
if (a) deposited in the U.S. mail, postage prepaid, certified mail, return
receipt requested; (b) sent by nationally recognized overnight courier in a
postpaid wrapper, or (c) by facsimile, addressed as follows:

                                    EXHIBIT B

                         CABLE SYSTEM DATA REQUIREMENTS
                     (TECHNICAL REQUIREMENTS FOR RF PLANTS)

         1. HSAC shall inspect and characterize Operator's one-way and two-way
RF cable plant to determine its feasibility for digital data transmission for
One-Way or Two-Way cable modems. This characterization shall focus on the
integrity of the cable plant against interference, intermodal distortions,
ingress, system noise, and transient/impulse noise.

         2. HSAC has established guidelines for Operator wishing to implement
digital data transmission on their cable plant. The guidelines shall recommend
CATV plant and equipment configurations to achieve a desired level of signal
reliability and quality in digital data transmission.

         3. Operator's RF/cable network must possess at least 400 MHz of
bandwidth (with at least one (1) 6 MHz channel reserved and dedicated to HSAC
Service/data flow) and otherwise continuously meet the following minimum
performance standards, measured at designated end-of-line test points throughout
the cable plant. Although constituting on a sample of pertinent issues, the
following test points should be selected such that they are representative of
all areas of the cable distribution system. Each Committed System's head-end
must also pass at least 4,000 homes.

         4. HSAC shall issue a written report detailing the RF/cable network
deficiencies and recommendations for improvements, i.e., the Attainment
Measures.

                          ANALOG PERFORMANCE PARAMETERS

                  a. In-Band Frequency Amplitude Response - Frequency response
of the cable network indicates the variation of system gain as a function of
frequency measured in dB. As a general guideline the amplitude characteristic
shall be within a range of +/- 2 dB from 0.75 MHz to 5.0 MHz above the lower
boundary frequency of a cable television channel, referenced to the average of
the highest and lowest amplitudes within these frequency boundaries.

                  b. VISUAL CARRIER-TO-NOISE RATIO (CNR) - The guideline that
HSAC establishes for CNR values is in accordance with FCC specification
76.6059(a)(7) that defines the ratio of RF visual signal level to system noise
to be not less than 43 dB.

                  c. DISTORTIONS - Distortions are defined as the ratio of
visual signal level to RMS amplitude of any coherent disturbances such as
intermod products, second and third-order distortions or discrete frequency
interfering signals not operating on proper offset assignments. The guideline
which HSAC has established is defined by FCC specification 76.605(a)(8) and
specifies the following: (i) the ratio of visual signal level to coherent
<PAGE>   33
disturbances shall not be less than 51 dB for non-coherent channel cable
television systems, when measured with modulated carriers; and (ii) the ratio of
visual signal level to coherent disturbances which are frequency-coincident with
the visual carrier shall not-be less than 47 dB for coherent channel cable
systems, when measured with modulated carriers and time-averaged.

                  d. HUM MODULATION - This is the variation in the amplitude of
a CW carrier at the power line frequency of 60 Hz or its harmonics induced as a
result of passing through the cable network. The HSAC guideline is defined by
FCC regulation 76.605(a)(10), which requires that the peak-to-peak variation in
visual signal level caused by undesired low frequency disturbances (hum or
repetitive transients) generated within the system, or by inadequate low
frequency response, shall not exceed 3 percent.

                  e. INGRESS AND IMPULSE NOISE LEVELS - Ingress is the level of
unwanted ambient signals leaking into the CATV plant as a result of such things
as imperfect shielding, loose connectors, cracked cabling and other plant
defects. Impulse noise has different spectral characteristics, which invades
spectral power densities as the frequency increases. Causes of impulse noise
include AC arcing of electric motors, power utility transformers, electrostatic
discharges, lightning and other transient sources that can produce a loss of
synchronization on digital transmission systems. In characterizing plant
performance, HSAC guidelines dictate that impairments should be maintained,
collectively, at a nominal averaged level not to exceed -50 dBc with respect to
video carriers, while recognizing that noise becomes visible in the video domain
at -55 dBc and shall thus cause deterioration to optimum synchronization of the
data carrier. Further, to maintain optimal RF downstream efficiency, HSAC
specifies impairments that cause end-of-line Carrier-to-Noise (CNR) performance
to drop below a minimum constant value of 43 dB is unacceptable and shall result
in interrupted high-speed data access service to the customer.

                  f. GROUP DELAY RESPONSE DISTORTION - No standards are
currently defined that specify minimum performance for this parameter. HSAC
guidelines however specify that as a general rule, delay response over the
return path should match that over the forward path. It is recommended that the
return frequencies be located 6 MHz from either the upper of lower limits of the
return bandwidth. This shall help minimize any group delay associated with the
roll-up or roll-off of the return spectrum.

                  g. RETURN PLANT VISUAL CARRIER-TO-NOISE RATIO (CNR) - HSAC
guidelines specify a minimum 36 dB visual CNR over the forward plant, defining
40 dB CNR as the more ideal threshold parameter. The expected higher level of
noise sources in the return path is mitigated by the reduction of video and data
carriers on the upstream.

                  h. RETURN IN-BAND FREQUENCY AMPLITUDE RESPONSE DISTORTION -
HSAC guidelines are consistent with FCC specification 76.605(a)(6), requiring
that the amplitude characteristic of a video carrier in the return direction to
be within a range of +/- 2 dB from 0.75 MHz to 5.0 MHz should also apply to
reverse video transmission.
<PAGE>   34
                  i. DISTORTION - HSAC expects that the level of CSO and CTB
distortions on the return path* shall be generally lower than the forward path,
due to the limited number of RF video carriers interacting with each other in
this sub-low frequency spectrum. To maintain the integrity of the return path
data transmission, HSAC would generally not expect to see more than two video
carriers in this spectrum. Therefore, HSAC guidelines for distortions in the
return path follow the same FCC specification 76.605(a)(8) which applies to the
forward path, which is not less than 51 dB for standard CATV systems (modulated
carriers and time averaged).

                  j. SIGNAL AVAILABILITY- HSAC in cooperation with the Operator
shall jointly maintain the same goal of providing reliable, uninterrupted signal
transport over both the forward and reverse plant*. Cable maintenance practices
that routinely interrupt service must be discouraged, and HSAC requests that
Operator provide it with advance notice of any interruptive testing or
maintenance practice that could result in the disruption of signal flow in
either the forward or return path. This advance notice is required in order that
proper customer service levels can be adequately maintained. In extreme cases,
high speed data customers can be notified of possible service disruptions.

                  k. TESTING - HSAC and Operator jointly agree to periodically
test the forward and return RF paths* of the CATV system. Such testing is
required to document performance parameter thresholds to the extent that
high-speed data services are not adversely affected. In the absence of such
routine testing, Operator agrees to notify HSAC of any adverse irregular signal
level condition on the plant, intermittent or continuous, which persists longer
than a 12-hour interval.

* Applies only to 2-way cable plant high speed data solution. Single path, 1-way
hybrid high speed data solutions need not adhere to these specifications.

SPLITTING OF GROSS REVENUES.

         D.1 Base Payments for HSAC Services. During the Term of this Agreement
as to a particular Committed System, if Operator designates HSAC to handle
billing of Data Subscribers, HSAC shall pay to the Operator an amount (i.e.,
"Operator's Share") equal to the percentages, by service category, as shown in
TABLE A, of Gross Revenues. If Operator decides to handle billing of Data
Subscribers, it shall pay to HSAC an amount (i.e., "HSAC's Share") equal to 100%
of Gross Revenues minus the percentage Operator's Share, by service category, of
Gross Revenues as shown in TABLE A.

               Two-Way Cable Express                   50%
               Other Optional Services                 50%
</TABLE>


         D.2 Data Subscriber Refunds. HSAC's local management shall have the
discretion to offer reasonable credits/refunds of Gross Revenues to Data
Subscribers resulting from Out-of-Compliance Events, which amounts shall be
deducted from the Operator's Share or added to HSAC's Share, as the case may be.
The determination of when Out-of-Compliance Events occur may be monitored and
reported by HSAC to the Operator on a monthly basis. As used herein, an
"Out-of-Compliance Event" occurs when the HSAC Services are rendered inoperable
or unusable due to the Committed Systems failing to meet System Data
Requirements or to a Service Failure traceable to the Operator's RF
Plant/Committed Systems (and such is not corrected within the period specified
in Section 7.3.4 of the Agreement) other than failures caused by a Force
Majeure.

         D.3 Settlement, Verification. Within thirty (30) days following the end
of each and every calendar month during the term thereof, the party handling
billing and collection shall deliver to the other party a statement (a
"Statement") showing the computation of the Operator's/HSAC's Share (derived
from the total number of Data Subscribers and Gross Revenues) in accordance with
this EXHIBIT E, which Statement shall specify amounts collected by region, and
remit same by negotiable instrument. Each party shall keep books and records
relating to the Operator's Share and HSAC's Share in accordance with generally
accepted accounting principles, consistently applied. During the Term hereof and
for three years thereafter, both HSAC and the Operator or their authorized
representatives may, at its own expense, visit each other's offices during
regular business hours, subject to suitable protections relating to
confidentiality and non-disclosure, to inspect and make extracts and copies of
any such books and records in order to determine the accuracy of the Statements.
<PAGE>   38
If any audit of Statements undertaken by either party in accordance with this
Section E.3 discloses a five percent (5%) or greater discrepancy from the
Statement(s) generated by the audited party, such party shall pay such amounts
to the auditing party and reimburse the auditing party for all costs incurred in
connection with such audit.

         D.4 Billing. Operator shall determine on a Committed System-by-System
basis which of Operator or HSAC will invoice Data Subscribers and collect Gross
Revenues. Operator shall provide HSAC access (both print copy and electronically
at HSAC's expense) to its Customer Lists and other customer databases on a
confidential basis for the purpose of developing and implementing a billing
system. HSAC and Operator shall work together to develop and implement an
electronic interface between HSAC and Operator for tracking and invoicing Data
Subscribers and vendors. With respect to those Committed Systems where HSAC in
invoicing the Data Subscribers, HSAC shall at its expense arrange for a data
exchange/software interface to be written and implemented which enables HSAC to
access and interface with Operator's billing system for purposes of updating on
a real-time basis both HSAC's and Operator's systems regarding the status of
Data Subscriber accounts so that such accounts may be automatically managed in
the same manner that as Cable Subscriber accounts are managed.

         D.5 Most Favored Nation. Notwithstanding anything set forth herein to
the contrary, HSAC agrees that during the term of this Agreement the Operator's
Share paid to Operator under paragraph E.1 above shall not be less than that
paid to other MSO or Cable System operators with whom HSAC contracts to provide
HSAC Services.

cable modem, cables and power supply equipment that we lease to you will at all
times be our property. You agree to immediately return to us in good condition

installing the ethernet/network interface card in your home computer at your
sales cost and expense. When any software associated with the ethernet card
and/or the cable modem is installed on your home computer, the system files may

software may disrupt the normal operations of your home computer and/or cause
the loss of files. Neither we nor your cable TV company are responsible for any
such loss. FOR THESE AND OTHER REASONS, WE RECOMMEND STRONGLY THAT YOU BACK-UP
ALL FILES PRIOR TO INSTALLATION.

the Service available to you twenty-four (24) hours per day, seven (7) days per
week. It is possible that there will be interruptions of Service. The Service
is an ethernet-like protocol service spread over a shared network which
co-exists on your cable television service, and you and all other users share a
finite amount of bandwidth. We will manage the Service to provide appropriate
bandwidth for as many customers as possible. HOWEVER, YOU ACKNOWLEDGE AND AGREE
THAT THE SERVICE MAY BE TEMPORARILY LIMITED, INTERRUPTED OR CURTAILED FOR MANY
REASONS INCLUDING WITHOUT LIMITATION TO SYSTEM CAPACITY LIMITATIONS IMPOSED OR
EXPERIENCED BY THE UNDERLYING COMMUNICATIONS CARRIES, GOVERNMENTAL ACTIONS,
FORCE MAJEURE, OR BECAUSE OF TEMPORARY EQUIPMENT OR SYSTEMS FAILURES OR
MODIFICATIONS, UPGRADES, MAINTENANCE, REPAIRS OR SIMILAR ACTIVITIES REQUIRED OR
APPROPRIATE IN CONNECTION WITH THE DELIVERY OR IMPROVEMENT OF THE SERVICE: the
Service may also affect the video programming portion of your cable television
service and you agree to waive any and all claims that are related to the
foregoing and to report any problems with your video programming services to
the local cable TV office by telephone.

CUSTOMER SUPPORT. We will attempt to provide you with "Help Desk" support which
can be accessed by telephone or by e-mail. Support may also be provided via
software provided by us. We will not provide support for the Service if you use
any hardware or software that has not been supplied by us or pre-approved in
writing by us. The telephone numbers and e-mail addresses for support services,
as well as hours of operation, are printed in the your Service Guide and are
available online. If you use or modify the hardware or any software we supply to
you, or the Equipment requires a visit to your residence or place of business
for repair or correction, we reserve the right to charge you for the visit and
labor required to correct the situation. We will not undertake to correct or
repair hardware or software which we do not supply.

NO LIABILITY FOR OBSCENE OR OTHER OFFENSIVE CONTENT, PORNOGRAPHY, ETC. You
acknowledge and understand that we only provide access to the Internet. We do
not publish (other than e-mail messages that we may from time to time send you
regarding the Service), control, monitor or restrict the information, programs,
e-mail, "chat rooms", interactive gaming or other material that is available to
your residence or place of business through the Internet, the World Wide Web, or
through USENET newsgroups. YOU MAY FIND OR ACCESS MATERIALS THROUGH OUR SERVICE
THAT YOU FIND TO BE SHOCKING, PROFANE, ABUSIVE AND/OR OFFENSIVE AND YOU ASSUME
THAT RISK. YOU MAY, IN FACT, FIND SOME MATERIAL TO BE OBSCENE, SEXUALLY
EXPLICIT, OR OTHERWISE INDECENT. YOU RECOGNIZE THAT CHARTER PIPELINE IS NOT
RESPONSIBLE FOR THIS MATERIAL, AND ACKNOWLEDGE THAT YOU HAVE BEEN NOTIFIED THAT
SUCH MATERIAL IS PRESENT. YOU ARE SOLELY AND EXCLUSIVELY RESPONSIBLE AND AT RISK
FOR (I) ALL INTERNET CONTENT ACCESSED VIA THE SERVICE BY YOU AND OTHER MEMBERS
OF YOUR HOUSEHOLD OR BUSINESS AND THEIR GUESTS, AND (II) PROVIDING SUITABLE
ADULT SUPERVISION OF ANY PERSON WHO IS LESS THAN EIGHTEEN (18) YEARS OF AGE AND

otherwise relating to such content accessed using the Service.

                                       3

NO LIABILITY FOR PARENTAL EMPOWERMENT SOFTWARE.  You may want to consider
installing blocking and filtering software developed by others that empower
parents and teachers to restrict their children's and students' access through
the Internet to objectionable or inappropriate material, and that protect or
prohibit them from corresponding with criminals or disclosing personal or other
information. Your acknowledge that we do publish such software, and agree that
neither we nor your cable company are in any manner responsible for the
effectiveness of these blocking and filtering technologies.

NO "HACKING", "SPAMMING" OR INFRINGEMENT OF OTHER'S RIGHTS.  You agree not to
publish on or over the Internet any content which violates or infringes upon the
rights of any other person. You also agree not to use the Service or cable modem
for any illegal purpose, to achieve unauthorized access to another party or
person's computer systems, software, data or other copyright or patent protected
material (commonly referred to as "hacking"). You agree not to interfere with
the use of the Service or the equipment by other customers or disrupt the
Service backbone network nodes or network services. You also agree not to send
unsolicited e-mail to our subscribers or anyone else without our explicit
written permission for each instance of communication. You further agree not to
upstream unsolicited distribution lists in e-mail or other mass unsolicited
e-mail (commonly referred to as "spam"). Your violation of any of these promises
is grounds for immediate termination of Service and this Agreement. If we are
challenged by a third party regarding the suitability of your content, we may,
at our sole discretion, suspend or terminate your access to the Internet through
our systems. We assume no liability whatsoever for any losses, claims, damages,
expenses, liabilities or costs (including legal fees) arising out of or in
connection with allegation, claim, suit or other proceeding based upon your use
of the Service or our Equipment or brought by any third party based upon or
arising out of the violation or infringement of any of the copyright, patent,
trademark, trade secret or other industrial or intellectual property rights or
contractual rights of any third party.

NO LIABILITY FOR UNAUTHORIZED ACCESS; ENCRYPTION; FILE-SHARING.  We treat
communications and data traffic on our through our Service as strictly
confidential and do not access, use or disclose contents of private
communications, except in limited circumstances as compelled or permitted by
law. However, since the Service is a shared network used by subscribers to
video programming and our Service which provides access to the Internet (and
beyond such network the Internet does not provide security), it is possible
that others may access or monitor your data traffic. You acknowledge that the
Internet systems use public access facilities to transmit voice and data
communications, and that the Service may accordingly not be completely private.
Accordingly, we do not warrant that any data or files sent or received by you
over the Service will not be subject to unauthorized access by others or that
other users (i.e., "hackers") will not gain access to your home computer. We
are not liable to you for any claims, loss, damages or cost that may result
from your lack of privacy on the Internet by virtue of your use of the Service.
IN ADDITION, THE SERVICE IS CONFIGURED TO DISABLE PEER-TO-PEER
NETWORKING/FILE-SHARING. IF YOU REQUEST THAT WE ENABLE THAT FEATURE, YOU WILL
BE REQUIRED TO SIGN A SEPARATE RELEASE AND LIABILITY WAIVER IN WHICH YOU
ACKNOWLEDGE THE EXTREME SECURITY RISKS TO YOUR COMPUTER AND THE PRIVACY OF YOUR
DATA FILES ASSOCIATED WITH SUCH NETWORKING. MOREOVER, IF YOU CHOOSE TO RUN
APPLICATIONS WHICH PERMIT OTHERS TO GAIN ACCESS TO YOUR COMPUTER, YOU DO SO AT
YOUR OWN RISK AND SHOULD TAKE APPROPRIATE SECURITY MEASURES. FOR THESE AND
OTHER REASONS, YOU MAY WANT TO CONSIDER INSTALLING THIRD-PARTY
AUTHENTICATION-ENCRYPTION SOFTWARE TO PROTECT YOUR DRIVES AND DATA/E-MAIL
FILES. We extend no warranty and accept no liability with respect to the
effectiveness of such software.

NO LIABILITY FOR VIRUSES.  We make no representation or warranty that any
software installed on your home computer or which you may download from the
Internet, any on-line service provider or other information provider (other
than us) does not contain any virus or other damaging or destructive attribute.

OTHER CHARGES; CREDIT CARD CHARGES.  You understand and acknowledge that you may
incur other costs and expenses for certain information, products and services
from persons, firms or entities other than us, including without limitation such
on-line services as America OnLine(R) or The Microsoft Network(R). You agree
that you shall be solely and exclusively responsible and liable for all such
charges, which are in addition to the fees and charges payable to us. With
respect to any Internet-based transactions that you undertake or participate in
through the Internet, you are solely and exclusively responsibility to make the
payments in connection with such transactions and to protect the security of all
credit information from unwanted or unauthorized charges. Neither we nor your
cable company shall have any liability or responsibility to you in connection
with Internet-based transactions, unauthorized use of your credit or debit
cards, credit availability or information, or your personal or financial

                  CHARTER PIPELINE INTERNET SERVICES AGREEMENT

                 CABLE MODEM ACCEPTABLE USE POLICY (AUP) 6/1/98


Your Internet access is facilitated by use of a cable modem, and consequently
cable modem-specific issues must be addressed. This Cable Modem AUP constitutes
an Addendum to the terms and conditions of the standard Charter Pipeline
Internet Services Agreement which you have assented to and do hereby consent to
by the continued use of the Service. The standard and cable AUPs are written in
plain English and apply equally to all CHARTER PIPELINE Network subscribers.
This AUP may be updated from time to time upon notice to you as described in
the Services Agreement.

CABLE MODEM ACCOUNT USAGE

Your Cable Modem account is a single user, non-server, non-commercial, unlimited
access account ONLY. CHARTER PIPELINE Network makes other accounts available to
you that will allow commercial or server access if you need it. These options
should be explored should your needs be other than the Cable Modem Standard
Account. If you wish to add a hub and provide access to more than one computer
in your household under your Cable Modem Standard Account, additional
fixed/static or dynamically-assigned IPs and bandwidth through-put can be
purchased for this purpose.

As noted previously, PROXY servers are NOT allowed under a residential Cable
Modem Standard Account, and customers who attempt to connect more than one
machine to a given modem via PROXY of any type (WinProxy, WinGate, etc.)
without paying for additional IPs will have their service disconnected. The
Cable Modem Standard Account cannot be used to run a server, whether commercial
or otherwise. The servers that CANNOT be run include, but are not limited to,
FTP, HTTP (Web), POP and SMTP (Mail), DNS, NNTP, and PROXY. These services are
capable of over-utilizing the bandwidth that all Charter Pipelineoration Cable
Modems share and, as such, are measured in a different way with regard to
payment. If we find you operating a server, you will be asked to remove it.
Should you not remove the server from usage, your account and Internet access
will be suspended, and your activity may be referred to local law enforcement
authorities. Repetitive suspensions (as defined by Charter Pipelineoration) for
violation of this rule will result in termination of Cable Modem Service
without the option to obtain a new account.

ANY USER OF THE CHARTER PIPELINEORATION SYSTEM THAT VIOLATES ANY OF THE ABOVE
RULES WILL BE SUBJECT TO ACCOUNT CANCELLATION AT OUR DISCRETION WITHOUT
RECOURSE OR REFUND.

                  CHARTER PIPELINE INTERNET SERVICES AGREEMENT

                          WAIVER AND RELEASE REGARDING
                            PEER-TO-PEER NETWORKING


"I", the undersigned customer, have requested that you, Charter Pipeline, as my
Service ISP, enable "peer-to-peer" networking privileges for my account. I
understand that once file-sharing is enabled, my Service will operate much like
a Local Area Network (LAN), which means that PC machine users on my cable
network will be able to identify and gain access to one another through the use
of broadcast frames, such as Windows(R) file sharing (called SMB [server message
block] or CIFS [common Internet file system]). This makes my computer and data
files vulnerable to unauthorized access, review and corruption.

I hereby represent, warrant, agree and acknowledge:

1)   that once you configure my Service to enable file-sharing privileges and
     run applications that permit others to gain access to my computer, you can
     neither monitor or control such access, and cannot protect me from hackers,
     viruses or corrupted files that may be introduced;

2)   that I am in sole and complete control of my password, and that I alone am
     responsible for taking appropriate security measure to encrypt my
     data/e-mail files or install third-party user-authentication software (I
     further agree that you extend no warranty and accept no liability with
     respect to the effectiveness of such software);

3)   that I understand completely the EXTREME security risks posed to my
     computer/data files and my privacy as a consequence of enabling such
     networking, and are nevertheless willing to do so at my own risk; and

4)   that you shall not be liable in any manner whatsoever as a result of any
     losses, damages, claims or costs that I may incur as a result of someone
     else gaining access, whether it be authorized, unauthorized (including
     accidental), to my PC.

I further waive any and all expectations of privacy or security that I may now
or hereafter have with respect to my online activities, and waive and release
you from any liability with respect to such peer-to-peer networking.
