         This Amendment No. 1 amends the Schedule 13D (the "Schedule 13D") filed
on June 1, 1998, by Comcast Corporation., a Pennsylvania Corporation, with
respect to Common Stock, par value $.01 per share, and Class A Common Stock, par
value $.01 per share, of Jones Intercable, Inc., a Colorado corporation whose
principal executive office is located at 9697 E. Mineral Avenue, Englewood,
Colorado 80112.

         Unless otherwise defined herein, each capitalized term used herein has
the same meaning ascribed to it in the Schedule 13D.

ITEM 1.  SECURITY AND ISSUER
         -------------------

         Item 1 is amended to read as follows: This Statement relates to shares
of Class A Common Stock, par value $.01 per share (the "Class A Common Stock"),
and Common Stock, par value $.01 per share (the "Common Stock"), of Jones
Intercable, Inc., a Colorado corporation (the "Company").

         The address of the Company's principal executive office is 9697 E.
Mineral Avenue, Englewood, Colorado 80112.

ITEM 4   PURPOSE OF TRANSACTION
         ----------------------

         Comcast acquired its right to acquire the Shares (as defined in Item 5)
as the result of having entered into the Amended and Restated Purchase and Sale
Agreement and the Comcast/Jones Agreement, both described in Item 6 below.
Comcast entered into the Amended and Restated Purchase and Sale Agreement and
the Comcast/Jones Agreement for the purpose of investing in, and obtaining
control of shares of capital stock sufficient to elect a majority of the board
of directors of, the Company. Upon the consummation of the transactions
contemplated by the Comcast/Jones Agreement, the Amended Option Agreement and
the Amended and Restated Purchase and Sale Agreement (the "Closing"), Comcast
will own a sufficient number of shares of Common Stock to elect a majority of
the board of directors of the Company and pursuant to the terms of the foregoing
agreements, the directors of the Company, other than the three directors jointly
designated by Jones and BTH pursuant to the Shareholders Agreement, will resign
seriatim from the board of directors of the Company at the Closing and will be
replaced by individuals designated by Comcast.

         Comcast may, subject to applicable securities laws, market conditions
and its assessment of the business prospects of the Company, acquire additional
shares of Class A Common Stock or Common Stock from time to time through open
market purchases or otherwise, as it determines in its sole discretion. Comcast
has not determined whether it will acquire additional shares or fixed any number
of shares of Class A Common Stock or Common Stock it might seek to acquire or
any amount of money it may be willing to invest in the Company. Comcast is
continuously evaluating the business and business prospects of the Company, and
its present and future interests in, and intentions with respect to, the Company
and, may, at any time decide to dispose of any or all of the Shares.


                                  Page 4 of 12
<PAGE>

         Except as specifically described above, Comcast, nor, to the best of
Comcast's knowledge, any of the persons named on Annex A of the Schedule 13D,
has any plan or proposal which would relate to or would result in any of the
following transactions:

         a. any extraordinary corporate transaction, such as a merger,
            reorganization or liquidation, involving the Company or any of its
            subsidiaries;

         b. a sale or transfer of a material amount of the assets of the Company
            or any of its subsidiaries;

         c. any change in the present Board of Directors or management of the
            Company, including any change in the number or term of directors or
            the filling of any vacancies of the Board of Directors;

         d. any material change in the present capitalization or dividend policy
            of the Company;

         e. any other material change in the Company's business or corporate
            structure;

         f. any change in the Company's charter, by-laws or instruments
            corresponding thereto or any other actions which may impede the
            acquisition of control of the Company by any person;

         g. the delisting of any class of securities of the Company from a
            national securities exchange or the ceasing to be authorized to be
            quoted in an interdealer quotation system of a registered national
            securities association;

         h. any class of equity securities of the Company becoming eligible for
            termination of registration pursuant to Section 12(g)(4) of the
            Securities Exchange Act of 1934; or

         i. any action similar to any of those enumerated above.


         Comcast intends periodically to review the Company's business affairs,
financial position and prospects. Based on such review, and on general economic,
industry and market conditions existing at the time, and on such other factors
as it may determine to be relevant, Comcast may consider additional or
alternative courses of action. Such actions may include the items specified in
(a) through (i) above or acquisitions of shares of Class A Common Stock or
Common Stock through open market purchases or otherwise. There can be no
assurance that Comcast will purchase any additional shares of Class A Common
Stock or Common Stock.

ITEM 5.  INTEREST IN SECURITIES OF THE ISSUER.
         -------------------------------------

         (a) Item 5(a) is amended to read as follows: Based on the Company's
annual report on Form 10-K for the fiscal year ended December 31, 1997, filed
with the Securities and Exchange Commission ("SEC") and information provided by
BTH and the Company, Comcast believes that as of August 11, 1998, the Company
had 35,973,892 shares of Class A Common Stock issued and outstanding and
5,113,021 shares of Common Stock issued and outstanding. For purposes of Rule
13d-3 promulgated by the SEC under the Securities Exchange Act of 1934, as
amended, Comcast may be deemed to have the right to acquire, and therefore to be

<PAGE>


the beneficial owner of, 12,782,500 shares of Class A Common Stock (which
represents approximately 35.5% of such class) (the "Class A Shares") and
2,878,151 shares of Common Stock (which represents approximately 56.3% of such
class) (the "Common Shares," collectively with the Class A Shares, the
"Shares"). Comcast's right to acquire the Shares is subject to the fulfillment
of conditions contained in the Amended and Restated Purchase and Sale Agreement,
the Comcast/Jones Agreement and the Amended Option Agreement (each as defined in
Item 6 below).

         Because of the existence of the Purchase and Sale Agreement the
Comcast/Jones Agreement and the Amended Option Agreement, Comcast may be deemed
pursuant to Rule 13d-5 (b) (1), to be a member of a "group" with BTH with
respect to the Class A Shares, and/or a member of a "group" with the Jones
Entities (as defined below) with respect to the Common Shares. Comcast, however,
expressly disclaims that it is a member of a "group" with BTH or with the Jones
Entities.

collectively:

         1. Glenn R. Jones, an individual residing in the State of Colorado.

is 80% owned by Jones 21st Century, Inc. (f/k/a Jones Digital Century, Inc.), a
Colorado corporation, and 20% owned by BCI (U.S. Cable) Limited (f/k/a Bell
Canada International BVI III Limited), a British Virgin Islands company. Jones
21st Century, Inc. is 95% owned by International and 5% owned by a member of Mr.
Jones' family.

         4. Jones Space Segment, Inc., a Colorado corporation ("JSS"). JSS is
81% owned by International and 19% by Mr. Jones. The principal business of JSS
is leasing satellite space on a communications satellite.

         5. Jones Global Group, Inc., a Colorado corporation ("JGG"). JGG is 80%
owned by International and 20% by the Company.

         6. Jones Interdigital, Inc., a Colorado corporation ("Interdigital").

         7. Jones Grantor Business Trust.

         8. Jones International Grantor Business Trust.

         To the best of Comcast's knowledge the following table sets forth the
shares of Class A Common Stock and Common Stock beneficially owned by BTH and
the Jones Entities. The following information is based solely on information
provided to Comcast by BTH and the Jones Entities.

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

         Item 6 is amended by adding the following:

         On August 12, 1998, BTH, Comcast, the Company and the Jones Entities
entered into the following documents (the "Transaction Documents"): (1) the
Agreement dated August 12, 1998, by and among Comcast, the Jones Entities and
certain affiliates of the Jones Entities named therein (the "Comcast/Jones
Agreement"); (2) the Amended and Restated Purchase and Sale Agreement, dated
August 12, 1998, by and among Comcast, BTH, US Cable and Intercable (the
"Amended and Restated Purchase and Sale Agreement"); (3) Amendment No. 1 to the
Option Agreements, dated August 12, 1998, by and among certain of the Jones
Entities and The Bank of New York (as successor agent to Morgan Guaranty Trust
Company of New York) as agent for BTH and Comcast (the "Amended Option
Agreement") and (4) the Agreement and Amendment No. 1 to Shareholders Agreement
by and among the Company, the Jones Entities, BTH, US Cable and Intercable. The
Transaction Documents contemplate, among other things, subject to the
satisfaction or waiver of certain conditions precedent, (i) the immediate
exercise of the Control Option and acquisition of the Common Shares by Comcast,
(ii) the acquisition by Comcast of the Class A Shares currently beneficially
owned by US Cable and (iii) the resignation of all of the directors of the
Company other than those certain directors mutually designated by Jones and BTH
pursuant to the Shareholders Agreement and the election of directors designated
by Comcast to fill such vacancies (the consummation of such transactions being
referred to herein as the "Closing"). In the event that the Closing is not
consummated on or prior to June 30, 1999, the Jones/Comcast Agreement will be
terminated and Comcast and BTH will alternatively proceed with the Initial
Purchase and the Final Purchase as more fully described in the Schedule 13D.

         Comcast will pay BTH approximately $500 million in cash at the Closing,
and in addition, will pay certain of the Jones Entities an aggregate of $200
million in cash to acquire the Common Shares pursuant to the Amended Option
Agreement. Comcast made a deposit of $50 million on August 12, 1998 under the
Comcast/Jones Agreement and certain of the Jones Entities pledged to Comcast
2,000,000 shares of Class A Common Stock of the Company (the "Pledged Shares")

                                  Page 8 of 12
<PAGE>


as security with respect to such deposit. Such pledged shares are not part of,
or subject to, the Amended Option Agreement. The $50 million plus interest will
be credited towards the $200 million to be paid to the Jones Entities at the
Closing pursuant to the Amended Option Agreement. Upon a termination of the
Comcast/Jones Agreement due to a breach of such Agreement by Comcast, the Jones
Entities can retain the $50 million deposit and Comcast will release the Pledged
Shares. Upon a termination of the Comcast/Jones agreement for any other reason,
the Jones Entities must return the $50 million deposit plus interest. The
Pledged Shares secure the Jones Entities obligation to so return such deposit.

         Also on August 12, 1998, the Shareholders Agreement was amended to
provide that at the Closing, certain of the provisions of the Shareholders
Agreement will terminate, principally those with respect to the programming
rights of Mr. Jones and International. As a result, Mr. Jones and International
will receive $25 million compensation from the Company for the termination of
such rights. The amended Shareholders Agreement also contemplates that a number
of other agreements between the Company, Mr. Jones, International and BTH will
also be terminated at the Closing. BTH's programming rights under the
Shareholders Agreement will be assigned to Comcast at the Closing.

         The Closing is conditioned on the satisfaction or waiver of certain
conditions precedent, including, without limitation, (i) expiration of all
applicable waiting periods under the Hart-Scott-Rodino Antitrust Improvements
Act of 1976, as amended, (ii) receipt of certain other governmental and
franchise approvals, (iii) absence of any governmental order, injunction or
applicable law prohibiting the transactions contemplated by the Transaction
Documents or requiring any party to divest a material portion of its assets as a
result of the consummation of the transactions, (iv) receipt of all material
third party consents and approvals, (v) truth and accuracy of certain
representations and warranties, (vi) absence of material adverse change to the
Company during the period commencing March 31, 1998 to and including the earlier
to occur of the Closing, the Initial Purchase and December 31, 1998, (vii)
compliance by each party in all material respects with the covenants required of
it pursuant to the Transaction Documents and (viii) certain changes to the
Company's severance plan. Comcast and the Jones Entities are not required to
agree to any consent decree related to objections by the Department of Justice
or the Federal Trade Commission to the contemplated transactions.

         Some of the covenants and agreements of Comcast include: entering into
a carriage agreement with Knowledge TV ("KTV") and Great American Country, Inc.
("GAC"), acknowledging certain agreements between the Company and the Jones
Entities and agreeing not to challenge their validity, waiving claims it may
have, if any, against the Jones Entities, using its reasonable best efforts to
cause the Company not to modify certain indemnification rights of officers,
directors and employees of the Company, performing its obligations and enforcing
its rights under the Comcast/BTH Agreement and not amending such agreement
without the consent of the Jones Entities, and paying a $1.5 million fee to
International for financial advisory, brokerage and consulting services rendered
to the Company.

         Some of the covenants and agreements of the Jones Entities include:
Jones and the Jones Nominees (as defined in the Shareholders Agreement)
resigning from the Company's board of directors and filling the vacancies with
individuals chosen by Comcast, offering the Company the opportunity to enter
into certain transactions following the Closing, releasing certain claims
against the BTH Entities and Comcast, causing KTV and GAC to amend certain
agreements with the Company, and refraining from entering into agreements with
the Company other than those specifically permitted under the Comcast/Jones
Agreements.

                                  Page 9 of 12
<PAGE>

         Some additional covenants of the Jones Entities with respect to the
Company include: using reasonable best efforts to ensure that the Company does
not perform certain actions without the consent of Comcast or pursuant to notice
provisions defined in the Transaction Documents, and using reasonable best
efforts to preserve the business and business organization of the Company.

         During the period beginning on August 12, 1998 and ending on the
earlier to occur of the Closing or the Final Purchase, as the case may be, BTH
and its affiliates will continue to own the Class A Shares and the Jones
Entities will continue to own the Common Shares and will continue to exercise
their rights and fulfill their obligations under the Shareholders Agreement. BTH
will consult with Comcast from time to time prior to exercising certain consent
rights, rights of first refusal, tag-along rights, etc., held by BTH under the
Shareholders Agreement as more fully described in the Schedule 13D. BTH has
agreed to cause the directors designated by it pursuant to the Shareholders
Agreement to resign at the Closing and to elect individuals designated by
Comcast to fill such vacancies.

         Pursuant to the Transaction Documents and conditioned upon the
consummation of the Closing, the Jones Entities, the Company and BTH have each
agreed to waive and release any claims they may have against each other, except
for those obligations, rights, actions, causes of action, claims, demands,
damages, costs, expenses or liabilities of each such party under the amended
Option Agreement or with respect to any judgment previously obtained in any
court of competent jurisdiction. Moreover, the Jones Entities, the Company, BTH,
US Cable and Intercable have agreed to take or to refrain from taking any and
all actions necessary or advisable to seek a stay of any proceedings relating to
that certain lawsuit brought by BTH against the Company, International, Jones
Internet Channel, Inc. and Glenn R. Jones, which was filed before the U.S.
District Court for the District of Colorado, including the appeal of the order
entered on May 5, 1998, until the earlier to occur of the Closing (at which time
the parties shall dismiss the litigation with prejudice) and the expiration or
termination of the Comcast/ Jones Agreement.

         agreement of sale providing for the sale or other disposition of such
         Managed System to the Company or one of its wholly owned Subsidiaries)

         been so obtained, be in effect and not be subject to withdrawal or
         appeal then the condition contained in this paragraph (ii) shall be
         deemed to be fulfilled as it relates to authorizations, consents or

         rule or regulation or any judgment, injunction, order or decree that
         has one or more of the effects described in clauses (a), (b) or (c) of
         the following paragraph (iv), provided that (x) if after the date
         hereof BTH or any of its Affiliates and (y) in the case of a Section

         a law, rule or regulation that has, or is reasonably expected to have,
         one or more of such effects, then this clause (iii) will not apply to
         any such law, rule or regulation.

                  (iv) There shall not then be instituted or pending any action
         or proceeding before any federal or state court or other Governmental

         Affiliates, or, in the case of a Section 3.1(a)(vi) Exercise, if after
         August 12, 1998 Comcast or any of its Affiliates enters into a new line
         of business and at such time there is a law, rule or regulation that
         has, or is reasonably expected to have, one or more of the foregoing
         effects, then this paragraph (iv) will not apply to actions or
         proceedings that seek to enforce such law, rule or regulation and (B)
         any actions or proceedings described in clause (a) or (b) will be based

         substance reasonably satisfactory to Purchaser.

                  (vi) The representations and warranties of Grantor contained

                  (vii) In the case of a Section 3.1(a)(vi) Exercise only, the
         Jones/Comcast Closing and the Simultaneous Closing shall have occurred
         on the same date as the Closing hereunder."

         8. Amendment of Section 3.3. Section 3.3 is hereby deleted in its
entirety and the following is substituted in lieu thereof:

         "SECTION 3.3 Purchase Price For the Optioned Shares. (a) The purchase
price per Optioned Share will be calculated as follows:

                  (i) (A) if the Trigger Date occurs prior to or on June 18,
         1995, 200% of the Market Value of a share of Class A Common Stock on
         the applicable Trigger Date, or (B) except in the case of a Section
         3.1(a)(vi) Exercise, if the Trigger Date occurs after June 18, 1995,
         the sum of (x) two-thirds of the Option Price on the applicable Trigger
         Date(1) and (y) one-third of 120% of the Market Value of a share of
         Class A Common Stock on the applicable Trigger Date1 or (C) in the case
         of a Section 3.1(a)(vi) Exercise, $69.4891 per Optioned Share, in each
         case reduced by

                  (ii) (A) the amount (or in the case of property other than
         cash, fair market value) of any dividends and distributions other than
         stock dividends paid, declared or otherwise distributed by the Company
         in respect of the Optioned Shares between the date hereof and the date
         of Closing and (B) in the case of a Section 3.1(a)(vi) Exercise, the
         amount of any Initial Consideration (as such term is used in the
         Jones/Comcast Agreement) which has been paid to Jones, Grantor or any
         party to the Related Option Agreements (or their respective Affiliates)
         in respect of the Optioned Shares plus interest accrued at the
         Applicable Rate (as such term is used in the Jones/Comcast Agreement)
         from the date such Initial Consideration was paid by Comcast to and
         including the date of Closing; provided that the amount of such Initial
         Consideration (plus interest) deemed to have been paid in respect of
         each Optioned Share shall be equal to the total amount of such Initial
         Consideration (plus interest) paid (and accrued) under the
         Jones/Comcast Agreement divided by the sum of the aggregate number of
         Optioned Shares actually acquired by Purchaser on the date of Closing
         under this Option Agreement plus the aggregate number of Optioned
         Shares (as such term is used in the Related Option Agreements) actually
         acquired by Purchaser on the date of Closing under the Related Option
         Agreements.(2) In the event any such dividends or distributions are
         made in property other than cash, the fair market value of such
         dividends or distributions will be determined pursuant to the valuation
         procedures described in Section 3.4(b).

- --------
1.       As an example of the calculation described in clause (i) (B), if on the
         applicable Trigger Date the Option Price were $50 per Share and the
         Market Value of a share of Class A Common Stock were $60 per share, the
         purchase price would be 2/3 of $50 ($33.3333) plus 1/3 of 120% of $60
         ($24), or $57.3333 (computed to four decimal places).

2        As an example of the calculation described in clause (ii)(B), if on the
         date of Closing the total amount of the Initial Consideration (plus
         interest) paid (and accrued) under the Jones/Comcast Agreement is equal
         to $51,000,000 and the sum of the aggregate number of Optioned Shares
         actually acquired by Purchaser on the date of Closing under this Option
         Agreement plus the aggregate number of Optioned Shares (as such term is
         used in the Related Option Agreements) actually acquired by Purchaser
         on the date of Closing under the Related Option Agreements is equal to
         2,700,000 Optioned Shares, the amount of the reduction per Optioned
         Share would be $51,000,000 divided by 2,700,000, or $18.8889 (computed
         to four decimal places).

         (b) The applicable "Trigger Date" will depend on the Exercise Period
under which Purchaser is delivering an Exercise Notice and will be earliest of
the following days:

                  (i)  in the case of an Exercise Period described in 
         clauses (i) or (ii) of Section 3.1(a),  the day of an Event or
         Resignation Event, as the case may be;

                  (ii) in the case of an Exercise Period described in clause
         (iii) of Section 3.1(a), the day immediately preceding the day on which
         Grantor delivers a Grantor's Notice;

                  (iii) in the case of an Exercise Period described in clause
         (iv) of Section 3.1(a), the day immediately preceding day on which
         Purchaser delivers an Exercise Notice;

                  (iv) in the case of an Exercise Period described in clause (v)
         of Section 3.1(a), the day immediately preceding the day of a Jones
         Bankruptcy Event; or

                  (v)  in the case of a Section 3.1(a)(vi) Exercise, the 
date hereof."

         9. Amendment of Section 3.5. Section 3.5 is amended by adding a new
subsection (c) thereto as follows:

         "(c) In the case of a Section 3.1(a)(vi) Exercise, the transactions
described in paragraphs (a) and (b) of this Section 3.5 shall occur on the same
date as the Jones/Comcast Closing and the Simultaneous Closing. If the
Simultaneous Closing and the Jones/Comcast Closing shall not have occurred on
the same date as the Closing, then the transactions described in paragraphs (a)
and (b) of Section 3.5 shall be rescinded and deemed not to have occurred. In
the case of a Section 3.1(a)(vi) Exercise, the procedures at the Closing shall
be as follows:

                  (i) the directors of the Company other than the Joint Nominees
         (as such term is defined in the Shareholders Agreement) shall resign
         seriatim and the remaining directors shall appoint individuals
         designated by Comcast to fill the vacancies created thereby, all as
         more fully described in the Jones/Comcast Agreement and the BTH/Comcast
         Agreement.

                  (ii) the transactions described in paragraphs (a) and (b) of
         Section 3.5 of this Agreement and of the Related Option Agreements
         shall occur; and

                  (iii) the transactions to be effected at the Simultaneous
         Closing shall occur."

         10. Amendment of Section 3.6 Section 3.6 is hereby deleted in its
entirety and the following is substituted in lieu thereof:

         "SECTION 3.6 Termination of Control Option. (a) The Control Option
shall terminate at 5:00 p.m. Denver time when the first Exercise Period
described in clauses (i), (iii) or (iv) of Section 3.1 expires (the "Termination
Time"), provided that, subject to the following paragraph (b), the Control
Option will not terminate if Purchaser has previously delivered to Grantor an
Exercise Notice. The Control Option shall also terminate (A) at such time as
Purchaser withdraws an Exercise Notice pursuant to Section 3.4(c), or (B) if the
Closing has been postponed pursuant to Section 3.2(b)(1), ten Business Days
after Grantor has delivered written notice to Purchaser stating that it believes
Purchaser is not using its reasonable efforts to consummate the Closing promptly
(which notice will set forth the basis for such claim) and Purchaser has failed
to use its reasonable efforts prior to the expiration of such period to cure the
problem identified by Grantor. The Control Option will not terminate solely
because of the expiration of the Exercise Periods described in clauses (ii) and
(v) of Section 3.1, or in the case of a Section 3.1(a)(vi) Exercise, upon the
termination of the Jones/Comcast Agreement and the failure of the Closing
hereunder to occur.

         (b) Notwithstanding anything in this Agreement to the contrary, (i) if
an Exercise Period is extended pursuant to the proviso in Section 3.1(a), the
Termination Time will occur twenty Business Days after such stay or prohibition
has been lifted and Purchaser has received notice of such action and (ii) each
Exercise Notice other than a Section 3.1(a)(vi) Exercise Notice shall terminate,
and be of no further force or effect, 18 months after its delivery, unless a
Closing shall have occurred by such time.

         (c) Notwithstanding the foregoing provisions of this Section 3.6, in no
event shall the Control Option expire or terminate prior to the termination of
the Jones/Comcast Agreement."

         11. Amendment of Section 4.1. Section 4.1 is hereby deleted in its
entirety and the following is substituted in lieu thereof:

         "SECTION 4.1 No Proxies for or Encumbrances on Optioned Shares. Except
as contemplated by this Agreement, until the termination of this Agreement
pursuant to Section 10.1, Grantor shall not, directly or indirectly, (i) grant
any proxies (other than a revocable proxy granted in connection with a meeting
of stockholders) or enter into any voting trust or other agreement or
arrangement with respect to the voting of any Optioned Shares, (ii) sell,
assign, transfer, encumber or otherwise dispose of, or enter into any contract,
option or other arrangement or understanding with respect to the direct or
indirect sale, assignment, transfer, encumbrance or other disposition of, any
Optioned Shares or (iii) seek or solicit any transaction or arrangement
described in clauses (i) and (ii). Grantor will notify Purchaser promptly (and
provide all details reasonably requested by Purchaser) if Grantor is approached
or solicited, directly or indirectly, by any person with respect to any of the
foregoing. Nothing herein shall be deemed to prevent or restrict (x) Grantor or
its Affiliates from voting its shares in its sole discretion on all matters,
except as otherwise agreed to between Grantor, its Affiliates, and BTH in the
Shareholders Agreement or otherwise, or between Grantor, its Affiliates and
Comcast in the Jones/Comcast Agreement or otherwise or (y) any Affiliate of
Grantor from taking or refraining from taking any other action not provided
herein or otherwise agreed to between Grantor, its Affiliates and BTH in the
Shareholders Agreement, the Jones/Comcast Agreement or otherwise or between
Grantor, its Affiliates and Comcast in the Jones/Comcast Agreement."

         12. Amendment of Section 4.2. Section 4.2 is hereby deleted in its
entirety and the following is substituted in lieu thereof:

         "SECTION 4.2 Further Assurances. BTH (and its agent) and Grantor will

documents and instruments and use their reasonable best efforts to secure such
consents and take all such further action as may be reasonably necessary in
order to consummate the transactions contemplated hereby or to enable Purchaser
and BTH or Comcast, as applicable, to enjoy all benefits and rights of the
Optioned Shares."

and warrants to Grantor that as of the date hereof and the date of the Closing
the Optioned Shares to be acquired upon exercise of the Control Option will be
acquired by Purchaser as the agent for, in the case of a Section 3.1(a)(vi)

its entirety and the following is substituted in lieu thereof:

9.1(d), Purchaser may cause any or all of the Optioned Shares to be transferred
of record into the name of Purchaser, in the case of a Section 3.1(a)(vi)
Exercise, to Comcast and in the case of any other exercise, to BTH, or in any
event, to any of their respective nominees. After notice thereof, Grantor will
promptly give to the Purchaser (or its designee) copies of any notices or other
communications received by it with respect to the Optioned Shares registered in
the name of Grantor, and Purchaser will promptly give to Grantor copies of any
notices and communications received by Purchaser, to the extent the same have
been delivered to Purchaser (or Comcast, BTH or a nominee) with respect to any
Optioned Shares registered in the name of Purchaser (or Comcast, BTH or a

         15. Amendment of Section 10.2(a). Section 10.2(a) is hereby deleted in
its entirety and the following is substituted in lieu thereof:

                                    ARTICLE I
                                SALE AND PURCHASE

Section 1.1. Purchase and Sale. (a) On the terms and subject to the conditions
of this Agreement, BTH agrees to sell, and Comcast agrees to purchase, for the
Purchase Price (i) the 49% Subsidiary Stock, the Initial Shares and, subject to
any rights pursuant to Section 4.5 of the Jones Companies Shareholders
Agreements, the Affiliate Stock all free and clear of any Claims, together with
all Payments received since the Initial Closing Date by BTH pursuant to the Fee
Letter and the Supply Services Agreement (the "Initial Purchase"), such sale and
purchase to be consummated as soon as reasonably practicable following the later
to occur of (x) the earlier of five Business Days following the expiration or
termination of the Jones/Comcast Agreement, and July 10, 1999 (or such later
date as the parties shall mutually agree to in writing) and (y) the expiration
of the 90-day period (or, at Comcast's option, such earlier time as it may
determine in its sole discretion) commencing on the date of this Agreement, and
in each case, assuming the satisfaction or waiver of the conditions precedent
set forth in Sections 5.1, 5.3, 5.4, 5.5, 6.1, 6.3, 6.4 and 6.5, or such later
date as the parties may agree (the first such day being the "Initial Closing

         (b) Notwithstanding the foregoing, on the terms and subject to the
satisfaction or waiver of the conditions precedent set forth in this Agreement,
the Initial Closing and the Final Closing shall occur simultaneously (the

Closing") of the transactions contemplated by the Jones/Comcast Agreement, or at
such later date as the parties may agree (the date the Simultaneous Closing
occurs being the "Simultaneous Closing Date"). If the Simultaneous Closing shall
not have occurred prior to the earlier of five business days following the
termination or expiration of the Jones/Comcast Agreement, and July 10, 1999,
then, assuming the conditions precedent set forth in Sections 5.1, 5.3, 5.4,
5.5, 6.1, 6.3, 6.4 and 6.5 shall have been satisfied or waived, the Initial
Closing shall take place as soon as reasonably practicable and in any event

Period expressing a desire to have BTH or the BTH Subsidiaries exercise their
rights under Sections 2.8, 3.1(b) or (c), 3.8, 4.2 or 5.1(b) of the Shareholders
Agreement, or if BTH or the BTH Subsidiaries are required to invest in

Agreement, at the time of delivery by Comcast of any such Preference Notice or,
in the case of a notice by BTH of its investment obligations pursuant to Section
3.1(a) of the Shareholder's Agreement within 5 Business Days of receipt by
Comcast thereof. Comcast and BTH agree to enter into a mutually satisfactory
escrow or security arrangement whereby Comcast shall make available to BTH or
the BTH Subsidiaries, as applicable, immediately available funds sufficient to
enable BTH or the BTH Subsidiaries to fulfill their payment obligations pursuant
to the applicable Section of the Shareholders Agreement and such funds shall be
held in escrow until immediately prior to such time as BTH or the BTH
Subsidiaries acquire the securities which are the subject of such transaction

         (e) In the event that BTH, the BTH Subsidiaries or their designees on
the Company's board of directors elect not to act in accordance with, or take
any action contrary to, any Notice of Preference of Comcast (whether actually
delivered pursuant to subsection (b) or whether deemed to have been delivered
pursuant to subsection (c) within the Preference Period), then BTH will make a
one-time payment to Comcast, within 5 days of demand by Comcast, of an amount
equal to $150,000,000, plus, if the Initial Closing has occurred interest at the
Applicable Rate accruing from the Initial Closing Date to and including the date
of such payment. No such payment shall be required of BTH with respect to a
transaction described in Section 3.6(b) of the Shareholders Agreement that has
occurred if (i) the directors of the Company designated by US Cable or any of
its Affiliates pursuant to the Shareholders Agreement shall have reasonably
concluded in good faith at the time they approved such transaction, to the
extent such consultation is reasonably practicable under the circumstances after
(x) consultation with and the receipt of advice from a nationally recognized law

Section 7.5. Exercise of the Control Option

         (a) BTH shall notify Comcast within twenty-four (24) hours after it
becomes aware that the Control Option becomes exercisable pursuant to the terms
of the Control Option Agreements. If Comcast, in its sole discretion, determines
that the Control Option should be exercised and so notifies BTH, then BTH shall
or shall cause Intercable or their agent to either (as directed by Comcast) (i)
exercise the Control Option and, upon satisfaction or waiver of the conditions
contained in Section 3.2(b) of the Option Agreement, purchase the Control Shares
or (ii) assign their rights under the Control Option Agreements in accordance
with Section 10.2(a)(iii) or 10.2(a)(iv) thereof to Comcast or a person selected
by Comcast. In the event that Comcast decides that the Control Option should be
exercised, it shall deliver to BTH a written notice directing BTH to, or to
cause its Affiliates or agents to, exercise the Control Option on a date
specified in such notice and Comcast shall deposit into an escrow account, with
Bank of New York acting as escrow agent, sufficient funds to consummate the
exercise of the Control Option and the purchase of the Control Shares; provided
however that if BTH or the BTH Subsidiaries fail to consummate the purchase of
the Control Shares such funds provided by Comcast shall be repaid to Comcast
plus any interest earned on such funds while held in escrow. BTH shall not, and
shall cause the BTH Subsidiaries and their agents not to, exercise the Control
Option unless so directed by Comcast. Notwithstanding any provision to the
contrary in this Agreement, Comcast and BTH acknowledge and agree that (i) the
Control Option has become immediately exercisable in certain circumstances
referred to in the Control Option Agreements as a "Section 3.1(a)(vi) Exercise"
and that the Control Option has been deemed to be so exercised as set forth in
the Control Option Agreements, (ii) at the time of the closing of the purchase
of the Control Shares pursuant to a Section 3.1(a)(vi) Exercise, Bank of New
York will be acting as agent for Comcast pursuant to each of the Control Option
Agreements (including the right to purchase the Control Shares), and (iii)
Comcast shall, at the time of the closing of the purchase of the Control Shares
pursuant to a Section 3.1(a)(vi) Exercise, pay the purchase price for the
Control Shares to the Jones Sellers pursuant to the Control Option Agreements
and Comcast shall not be required to deposit such funds in escrow as provided in
this Section 7.5(a).

         (b) In the event that Intercable's inability to satisfy one or more of
the conditions contained in Section 3.2(b)(i)-(vi) of the Control Option
Agreements is due to a Change in Law (as defined in the Control Option
Agreements) after the date of this Agreement and prior to the delivery of an
exercise notice pursuant to the Control Option Agreements, and such inability to
satisfy such conditions would prevent Intercable from delivering the Control
Shares to Comcast as provided herein, then Intercable shall have the right to
offer the Control Option to Jones in accordance with the terms, conditions and
procedures specified in Section 7.2 of the Control Option Agreements; provided
that Intercable agrees that it shall not exercise such right to offer the
Control Option to Jones prior to the termination of the Jones/Comcast Agreement.
In the event that Jones fails to elect to purchase the Control Option pursuant
to the offer referred to in the previous sentence, then Intercable shall assign
the Control Option to Comcast (or a Person designated by Comcast) pursuant to
Section 10.2(a)(ii) of the Control Option Agreements and the condition contained
in Section 8.5(f) shall be satisfied. In the event that Jones elects to purchase
the Control Option pursuant to the offer referred to in the first sentence of
this Section 7.5(b), the condition contained in Section 8.5(f) shall not be
satisfied and BTH shall have the right to retain any proceeds of such purchase
by Jones.

Section 7.6. Litigation. BTH shall not take any action or refrain from taking
any action relating to the Litigation without first consulting with Comcast;
provided that, in consideration of Comcast's entering into the Jones/Comcast
Agreement and this Agreement, BTH hereby releases, effective as of the date on
which the Closing Date (as defined in the Jones/Comcast Agreement) and the
Simultaneous Closing Date shall both have occurred, all claims for monetary
damages that it has asserted, or may assert, against the Company, the Jones
Sellers and their respective officers, directors and Affiliates in connection
with the subject matter of the Litigation as provided in the Agreement and
Amendment No. 1 to Shareholders Agreement of even date herewith. BTH agrees to
take any and all actions necessary or advisable to stay any and all proceedings
relating to the Litigation until the first to occur of (i) the date on which the
Closing Date (as defined in the Jones/Comcast Agreement) and the Simultaneous
Closing Date shall both have occurred or (ii) the termination of the
Jones/Comcast Agreement.

marketable title to, and to deliver to Comcast a certificate or certificates
representing, all of the shares of capital stock of the Company owned

condition in Section 8.5 or 8.6 is not reasonably possible despite the parties
reasonable best efforts to ensure the same, the parties will take the following
actions as an alternative to the Final Closing:

         (a) If the Final Closing has not occurred due to (i) a failure to
satisfy the conditions specified in Section 8.6(d) or (ii) a failure to satisfy
the conditions specified in Section 8.5(f) because Intercable shall have
exercised the Control Option pursuant to Comcast's instructions but shall have
failed to consummate the purchase of the Control Shares due to the failure of
Intercable to satisfy one or more of the conditions contained in Sections
3.2(b)(i)-(vi) of the Control Option Agreements and Intercable is unable to

Subsidiaries pursuant to Section 2.8, 3.1, 3.8, 4.2 or 5.1(b) of the

                                      -24-


<PAGE>

         (b) If the Final Closing has not occurred due to (i) a failure to
satisfy the conditions contained in Sections 8.5(a)(ii); or (ii) a failure of
the conditions contained in Section 8.5(c), 8.5(d) or 8.5(f) to be satisfied or
waived or (iii) due to a failure of the conditions contained in Section 8.6(e)
or 8.6(f) to be satisfied or waived, then BTH shall pay to Comcast an amount
equal to $250,000,000 plus interest at the Applicable Rate from the Initial
Closing Date and deliver to Comcast any shares of capital stock of the Company
acquired by BTH or the BTH Subsidiaries pursuant to Sections 2.8, 3.1, 3.8, 4.2
or 5.1(b) of the Shareholders Agreement with funds provided by Comcast together
with any dividends or distributions upon or with respect to such shares, and
Comcast shall deliver to BTH all of the 49% Subsidiary Stock acquired by Comcast
at the Initial Closing together with any dividends or distributions upon or with
respect to such shares and Comcast shall have no obligation to pay to BTH the
Final Closing Payment; provided, however, that (A) in the case of a judgment,
injunction, order or decree referred to in clause (i) above that is based upon
the effect of any (x) agreement, arrangement or understanding other than the
Jones/BTH Agreements, or (y) any parole evidence or other matters extrinsic to
the Jones/BTH Agreements, in the case of either clause (x) or (y) above,
existing prior to the date of this Agreement or (B) the failure of the
conditions specified in Section 8.5(c) or 8.5(d) to be satisfied or waived; then
in lieu of the $250,000,000 payment referred to above BTH shall pay to Comcast
an amount equal to $272,000,000.

         (c) In the event that (i) a judgment, injunction, order or decree of
any court of competent jurisdiction invalidating, terminating, nullifying or
voiding this Agreement has become final and non-appealable or (ii) the Final
Closing fails to occur due to a failure to satisfy the condition specified in
Section 8.5(g), then in the case of either (i) or (ii), BTH shall pay to Comcast
an amount equal to $250,000,000 plus interest at the Applicable Rate from the
Initial Closing Date and deliver to Comcast any shares of capital stock of the
Company acquired by BTH or the BTH Subsidiaries pursuant to Sections 2.8, 3.1,
3.8, 4.2 or 5.1(b) of the Shareholders Agreement with funds provided by Comcast
together with any dividends or distributions upon or with respect to such
shares, and Comcast shall deliver to BTH all of the 49% Subsidiary Stock

<PAGE>

         (d) If the Final Closing has not occurred due to the inability of
Comcast to take delivery of or take title to the Control Shares, the Class A
Shares or any other shares of capital stock of the Company or the Remaining
Subsidiary Stock but Intercable shall have exercised the Control Option and
purchased the Control Shares, then Comcast shall pay to BTH an amount equal to
the Final Closing Payment together with interest accrued at the Applicable Rate
from the Initial Closing Date through the Final Closing Date and BTH agrees that
Intercable shall take delivery of the Control Shares and US Cable and Intercable
shall hold the Control Shares and other shares of capital stock of the Company
owned by US Cable and Intercable including, without limitation, the Class A
Shares and any shares of capital stock of the Company acquired by BTH or the BTH
Subsidiaries pursuant to Section 2.8, 3.1, 3.8, 4.2 or 5.1(b) of the
Shareholders Agreement with funds provided by Comcast, in each case together
with any dividends or distributions upon or with respect to such shares (the
"Trust Stock") in trust for Comcast's benefit and, to the maximum extent
permitted by law, subject to Comcast's direction.

         At such time as either the Trust Stock is sold or disposed of or
Comcast is permitted under applicable law to take possession of the Trust Stock,
Comcast may at its option elect to either take possession of the Remaining
Subsidiary Stock or exchange the shares of Subsidiary Stock which Comcast
received in the Initial Closing for all of the shares of capital stock of the
Company beneficially owned by BTH and the BTH Subsidiaries (including, if any
portion of the Trust Stock shall have been sold or disposed of prior to such
exchange, the Net Proceeds of such sale or disposition). Comcast agrees that, if
the Trust Stock (including any Net Proceeds) has not been transferred to Comcast
or sold or otherwise disposed of by the BTH Subsidiaries at Comcast's direction
within one year of the date Intercable consummates the purchase of the Control
Shares, Comcast shall direct BTH and the BTH Subsidiaries to transfer either the
Remaining Subsidiary Stock or the Trust Stock (including any Net Proceeds) to an
independent trustee or other third party designated by Comcast.

         (e) In the event BTH shall have paid $150,000,000 to Comcast pursuant
to Section 7.3 hereof, the payments referred to in paragraphs (a), (b), (c) and
(d) above shall be reduced by such amount and all interest on such payments
shall be calculated on such reduced amount.

         (f) In the event BTH or Comcast shall be prevented from transferring or
receiving title to or possession of any of the Remaining Subsidiary Stock or
shares of capital stock of the Company to Comcast, as contemplated in paragraph
(a), (b), (c) or (d) above, the parties shall use their reasonable best efforts
to give the parties the benefits they would have received if such shares of the
Remaining Subsidiary Stock or shares of capital stock of the Company had been so
transferred, including to the extent legally permissible the transfer of shares
of the Company and rights held by the BTH Subsidiaries and placing such shares
of the capital stock of the BTH Subsidiaries or shares of capital stock of the
Company in trust.

consent of Comcast and BTH; (ii) by either Comcast or BTH on July 10, 1999, if
the Initial Closing or the Simultaneous Closing has not occurred; provided that
the right to terminate this Agreement under this Section 9.1(a)(ii) shall not be
available to any party whose failure to fulfill any obligation under this
Agreement shall have been the cause of or shall have resulted in the failure of
the Initial Closing or the Simultaneous Closing to occur on or prior to such
date; and (iii) if a statute, rule or regulation is enacted or adopted
subsequent to the date of this Agreement but prior to the Initial Closing Date
which would have the effect of prohibiting Comcast from purchasing or owning the

shall have no further obligation to any other party hereto.

         (b) Notwithstanding the foregoing, in the event any injunction, order
or similar restraint has been issued by a court of competent jurisdiction (other
than by virtue of any suit brought by a party to this Agreement), the
termination date referred to in the foregoing clause (a) shall, upon the mutual
agreement of the parties, be extended until the earlier of (i) the 10th day
after such injunction, order or restraint shall have been dissolved or (ii) the
date such injunction, order or restraint shall have become permanent and no
longer subject to appeal, as the case may be.

termination pursuant to this Article IX; provided, however, that (a) the

any termination of this Agreement and (b) nothing herein shall relieve any party
from any liability for any prior breach of this Agreement.

Agreement to the contrary notwithstanding, if any of the conditions specified in

respect to claim for a breach of a representation or warranty (other than

Section 11.5. Notice: Defense of Claims. An indemnified party may make claims
for indemnification hereunder by giving written notice thereof to the
indemnifying party within the period in which indemnification claims can be made
hereunder. If indemnification is sought for a claim or liability asserted by a
third party, the indemnified party shall also give written notice thereof to the
indemnifying party promptly after it receives notice of the claim or liability
being asserted, but the failure to do so shall not relieve the indemnifying
party from any liability except to the extent that it is prejudiced by the
failure or delay in giving such notice. Such notice shall summarize the bases
for the claim for indemnification and any claim or liability being asserted by a
third party. Within twenty (20) days after receiving such notice the
indemnifying party shall give written notice to the indemnified party stating
whether it disputes the claim for indemnification and whether it will defend
against any third party claim or liability at its own cost and expense. If the
indemnifying party fails to give notice that it disputes an indemnification
claim within twenty (20) days after receipt of notice thereof, it shall be
deemed to have accepted and agreed to the claim, which shall become immediately
due and payable. The indemnifying party shall be entitled to direct the defense
against a third party claim or liability with counsel selected by it (subject to
the consent of each indemnified party, which consent shall not be unreasonably
withheld) as long as the indemnifying party has acknowledged in writing that it
is obligated to indemnify the indemnified party for such claim pursuant to this
Article XI and is conducting a good faith and diligent defense and only money
damages are at issue. Each indemnified party shall at all times have the right
to fully participate in the defense of a third party claim or liability at its
own expense directly or through counsel; provided, however, that if the named
parties to the action or proceeding include either both the indemnifying party
and/or one or more indemnified parties and an indemnified party is advised in
writing by counsel to the indemnified party that representation of both parties
by the same counsel would be inappropriate under applicable standards of
professional conduct, an indemnified party may engage separate counsel at the
expense of the indemnifying party. If no such notice of intent to dispute and
defend a third party claim or liability is given by the indemnifying party, or
if a good faith and diligent defense is not being or ceases to be conducted by
the indemnifying party or if the claim or liability includes other than money
damages, the indemnified party shall have the right, at the expense of the
indemnifying party, to undertake the defense of such claim or liability (with
counsel selected by the indemnified party), and to compromise or settle it,
exercising reasonable business judgment. If the third party claim or liability
is one that by its nature cannot be defended solely by the indemnifying party,
then the indemnified party shall make available such information and assistance
as the indemnifying party may reasonably request and shall cooperate with the
indemnifying party in such defense, at the expense of the indemnifying party.

Section 11.6. No Right of Contribution. After the Initial Closing, neither of
BTH nor Comcast shall have any claim for contribution against the BTH
Subsidiaries in respect of any liability any such party may have to any BTH
Indemnified Party or Comcast Indemnified Party under this Agreement.

                                  SCHEDULE 3.10

                  1. Organization and Standing of the Company. The Company and
each of its subsidiaries, is a corporation duly organized, validly existing and
in good standing under the laws of the jurisdiction of its incorporation or
organization with full corporate power and authority to own, lease, use and
operate its properties and to conduct its business as and where now owned,
leased, used, operated and conducted. The Company and each of its subsidiaries
is duly qualified to do business and in good standing in each jurisdiction in
which the nature of the business conducted by it or the property it owns, leases
or operates requires it to so qualify, except where the failure to be so
qualified or in good standing in such jurisdiction individually or in the
aggregate would not reasonably be expected to have a Material Adverse Effect on
the Company. The Company and each of its subsidiaries is not in default in the
performance, observance or fulfillment of any provision of their respective
certificate of incorporation or by-laws.

                  2. Organizational Documents. The certificate of incorporation
and bylaws of the Company are as set forth in Exhibits 3.1-3.4 to the Company's
Form 10-K for the fiscal year ended December 31, 1997, as filed with the SEC and
have not been amended, modified, or rescinded and they remain in full force and
effect.

                  3. Capitalization. As of February 20, 1998, the Company's
authorized capital stock consisted solely of (a) 60,000,000 shares of Class A
Stock, of which (i) 35,578,398 shares were issued and outstanding, and (ii)
1,353,083 shares were reserved for issuance upon the exercise of outstanding
options, and no other shares were reserved for issuance for any other purposes;
and (b) 5,550,000 shares of Common Stock of which 5,113,021 shares were issued
and outstanding, and no shares were reserved for issuance for any purpose. Since
February 20, 1998 through the date of the Agreement and through the Initial
Closing Date, there have been no increases to any of the foregoing amounts other
than increases in the number of shares of Class A Stock outstanding by reason of
the exercise of the foregoing options, which exercise has reduced the number of
shares of Class A Stock reserved for issuance pursuant to options by a
corresponding amount. Since the date of the Agreement, there have been no
additional issuances of shares of Class A Stock or Common Stock other than
issuances of Class A Stock upon exercises of stock options outstanding on the
date of this Agreement. Except for the stock options described in the preceding
sentence, since the date of the Agreement there have been no subscriptions,
options, warrants, or other rights, convertible securities, agreements,
arrangements, or commitments of any character relating to the issued or unissued
capital stock of the Company to which the Company or any of its subsidiaries is
a party, or by which any of their properties are bound or affected, or
obligating the Company or any of its subsidiaries to issue or sell any shares of
capital stock of, or other equity interests in, the Company.

                  4. Public Filings. Since December 31, 1995, the Company has
timely filed all material forms, reports, and documents (the "Company Public
Reports") required to be filed with the SEC and the National Association of
Securities Dealers and other US federal or state securities law authorities,
exchanges or self-regulatory bodies (the "Securities Authorities") prior to the
Initial Closing Date. The Company Public Reports (including, without limitation,
any financial statements or schedules included therein) filed on or prior to the
Initial Closing Date (i) have been prepared in compliance with the requirements
of applicable law, and (ii) did not at the time of filing (or, if amended,
supplemented, or superseded by a filing prior to the Initial Closing Date, on
the date of that filing) contain any untrue statement of a material fact or omit
to state a material fact required to be stated therein or necessary in order to
make the statements therein, in the light of the circumstances under which they
were made, not misleading.

                  5. Financial Statements. Each of the consolidated financial
statements contained in the Company Public Reports filed on or prior to the
Initial Closing Date and the Company's audited consolidated financial statements
for the years ended December 31, 1997, 1996 and 1995 and the quarter ended March
31, 1998 (together, the "Financial Statements") (including, in each case, any
related notes thereto) have been prepared in accordance with generally accepted
accounting principles ("GAAP") applied on a consistent basis throughout the
periods involved (except as may be indicated in the notes thereto), and each of
them present fairly in all material respects the consolidated financial position
of the Company and its Subsidiaries at their respective dates and the
consolidated results of their operations and cash flows for the periods
indicated, except that unaudited interim financial statements included in any
quarterly reports may have been subject to normal and recurring year-end
adjustments that were not expected to be material in amount.

                                    AGREEMENT

         WHEREAS, the Company, Jones, International and BTH are parties to a
certain Shareholders Agreement originally dated as of December 20, 1994
providing for certain rights and obligations regarding their relationships (the
"Original Shareholders Agreement");

agreement regarding certain matters relating to the transactions contemplated by

         THEREFORE, in consideration of the mutual covenants contained herein
and intending to be legally bound hereby, the parties agree as follows.

                                      -1-
<PAGE>

1. Closing.

                  (a) The closing of the transactions contemplated hereby (the
"Closing") shall take place on the same date as the Simultaneous Closing at the
offices of Dechert Price & Rhoads, 4000 Bell Atlantic Tower, 1717 Arch Street,
Philadelphia, PA 19103 as soon as is reasonably practicable after the date on
which the conditions specified in Sections 3 and 4 shall be fulfilled or waived.
The date on which the Closing occurs is sometimes referred to herein as the
"Closing Date". Comcast shall notify to the extent possible the Jones Entities
of the expected Closing Date no less than three days prior to the Closing Date.

                  (b) At the Closing, the parties agree that the following
events shall occur in the following sequence:

                           (i) The directors of the Company other than the Joint
Nominees (as defined in the Shareholders Agreement) shall resign seriatim and
the remaining directors shall appoint individuals designated by Comcast to fill
the vacancies created thereby.

                           (ii) The purchase and sale of the Control Shares
shall occur (the "Option Closing").

                           (iii) The Simultaneous Closing shall occur.

                  (c) If the Option Closing and the Simultaneous Closing under
the Comcast/BTH Agreement shall not have occurred on the Closing Date, then all
of the transactions and agreements to be effected at the Closing shall be
rescinded and deemed not to have occurred.

2. Initial Consideration.

                  (a) In consideration for the Jones Entities entering into this
Agreement, Comcast agrees that, on the date that the Jones Entities pledge the
Pledged Shares (as defined herein) pursuant to Section 9(e) hereof, it will
deposit with International $50,000,000 in cash (the "Initial Consideration") by
wire transfer of immediately available funds to a bank account designated by
International. The parties acknowledge and agree that the Initial Consideration,
together with interest thereon, shall be a credit against the aggregate Purchase
Price (as such term is defined in the Option Agreements) required to be paid
upon the closing of the purchase and sale of all of the Optioned Shares, as more
fully described in the Option Agreements.

                  (b) In the event that this Agreement is terminated for any
reason other than pursuant to Section 16(c) hereof or the Closing fails to occur
on the Closing Date for any reason other than as set forth in Section 16(c), the
Jones Entities agree to pay to Comcast, upon delivery by any Jones Entity of any
notice of termination or upon demand by Comcast, an amount equal to the Initial
Consideration plus interest calculated at the Applicable Rate from the date the
Initial Consideration is deposited with the Jones Entities to and including the
date the Jones Entities repay such Initial Consideration. "Applicable Rate"
means an interest rate per annum at which deposits in United States dollars
appears on page 3750 (or any successor page thereto) of the Dow Jones Telerate
Screen for a ninety day period, plus 1/2%. The Applicable Rate for any period
shall be determined as of the date the Initial Consideration is deposited with
the Jones Entities, and shall be adjusted quarterly on the first business day of
each January, April, July and October through the date the Jones Entities repay
the Initial Consideration (or the Initial Consideration is credited against the
Purchase Price payable in respect of the Optioned Shares pursuant to the Option
Agreements).

                                      -2-
<PAGE>

                  (c) In the event that this Agreement is validly terminated by
the Jones Entities pursuant to Section 16(c) hereof or the Closing fails to
occur on the Closing Date for the reason set forth in Section 16(c), the parties
agree that the damages suffered by the Jones Entities would be speculative and
difficult to measure and, therefore, the Jones Entities shall be entitled to
retain the Initial Consideration (together with any interest earned thereon by
the Jones Entities) as liquidated damages and a sole remedy for Comcast's breach
of its obligations under this Agreement; provided however, that nothing
contained in this clause (c) shall preclude the Jones Entities from seeking
specific performance of Comcast's obligations hereunder prior to the termination
of this Agreement.

                  (d) The Jones Entities shall be entitled to retain the Initial
Consideration (together with any interest earned thereon by the Jones Entities)
upon consummation of the purchase and sale of the Optioned Shares.

         3. Conditions to the Obligations of Comcast. The obligation of Comcast
to take any action required to be taken by Comcast at or following the Closing
shall be subject to the fulfillment or waiver of each of the following
conditions:

                  (a) The waiting period (including any extension thereof
resulting from additional inquiries, if any) under the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended (the "HSR Act") applicable to the
consummation of the transactions contemplated hereby (including the consummation
of the exercise of the Control Option and the Simultaneous Closing under the
Comcast/BTH Agreement) shall have expired or been earlier terminated.

                           (v) declare or make any provision for payment of, or

deliver to Comcast a written notice describing in reasonable detail the action
proposed to be taken and expressly requesting Comcast's consent to such action
pursuant to this Section 10. Such notice shall be accompanied by such additional
information as is reasonably required to enable Comcast to evaluate such
proposed action. Upon receipt of such notice and of any additional information
as may be reasonably requested by Comcast, Comcast will have ten Business Days
to exercise its right not to consent to such proposed action. If no response is
received by the Jones Entities from Comcast prior to the expiration of such time
period, the proposed action will be deemed to have been approved by Comcast. The
Jones Entities shall not be in breach of this Section 10 if such action is taken
in compliance with the procedure set forth in this paragraph.

         11. Preservation of Business. Between the date hereof and the earlier
of the Closing Date and the date this Agreement is terminated, the Jones
Entities will use their reasonable best efforts to preserve, and to cause the
Company to preserve, the business organization of the Company intact and to
preserve the goodwill of the Company's (and its Subsidiaries') suppliers,
clients and others having business relationships with the Company (or its
Subsidiaries) and to operate their respective businesses in the ordinary course,
consistent with past practices.

         12. Access.

         (a) Immediately upon execution of this Agreement, the Jones Entities
shall use their best efforts to cause the Company to provide Comcast and its
representatives complete access to the books, records, agreements, employees,
accountants and the offices of the Company and its Subsidiaries for the purposes
of making such investigation of the business of the Company and its Subsidiaries
as Comcast shall deem necessary; provided, however, that such investigation
shall not unreasonably interfere with the operations of the Company. Between the
date hereof and the termination of this Agreement, Jones agrees to provide to
Comcast copies of all information delivered to BTH or any Investor Nominee in
accordance with the Shareholders Agreement. In addition, the parties agree that
the BTH Entities shall be permitted to provide to Comcast all information
regarding the Company received by them or any Investor Nominee after the date
hereof; provided that any such information provided to Comcast shall be subject
to paragraph (b) below.

         (b) From the date hereof to the earlier of the Closing Date or the date
which is one year after the termination of this Agreement, Comcast and its
officers, directors, employees, representatives and Affiliates will use
reasonable care to avoid disclosure to third parties of proprietary information
(whether received by Comcast from the Company, the Jones Entities or the BTH
Entities) relating to the Company, except as specifically (and only to the
extent) required to be disclosed by applicable law or administrative or legal
process. For purposes of Comcast's obligations under this Section 12, reasonable
care means the same degree of care that Comcast exercises with respect to
similar types of its own proprietary information. It is understood and agreed
that: (i) Comcast will (to the extent reasonably possible) notify the Jones
Entities in writing prior to any proposed disclosure of such nonpublic
information in response to the requirements of applicable law or administrative
or legal process in order to enable the Jones Entities to seek an appropriate
protective order; (ii) Comcast may disclose any information which (x) is or
becomes publicly available other than as a result of a disclosure of Comcast in
breach of this Agreement, (y) was known to the party receiving such information
prior to the receipt thereof other than as a result of a disclosure by Comcast
in breach of this Agreement, or (z) was previously independently developed by
the party receiving such information without the assistance of Comcast. In the
event that the transactions contemplated hereby do not take place, all original
documents shall be returned by Comcast if requested by the providing party
within thirty (30) days of the termination of this Agreement; otherwise, Comcast
shall dispose of any such original documents in the normal course of Comcast's
business.

         13. Costs and Expenses. Whether or not the transactions contemplated
hereby are consummated, each party shall bear its own costs and expenses. The
Jones Entities agree to indemnify, defend and hold harmless Comcast and its
Affiliates and each of their respective directors, officers, employees, agents,
contractors, successors and assigns from any claims by or liabilities to any
third party with whom the Jones Entities or their agents had discussions
regarding the disposition of their interests in the Company arising from the
consummation of the transactions contemplated hereby.

the Closing or termination of this Agreement, the Jones Entities, on behalf of

party relating to or enter into any contract, agreement, understanding or
arrangement with respect to the sale of the Common Stock of the Company owned
beneficially or of record by the Jones Entities or a transaction involving the
merger, consolidation or sale of the Company or substantially all of the
Company's assets.

         16. Termination. This Agreement may be terminated as follows: (a) by
mutual written consent of Comcast and the Jones Entities; (b) by Comcast upon

Entities have materially breached any of their obligations contained herein and

this Agreement and (z) Comcast shall not be in material breach of its
obligations contained herein or in the BTH/Comcast Agreement; (c) by the Jones
Entities upon written notice to Comcast of such termination if (x) Comcast has
materially breached any of its obligations contained herein and Comcast has
failed to cure such breach within fifteen (15) calendar days of receipt of
written notice of such breach from the Jones Entities, (y) all of the conditions

Agreement of even date herewith; (d) if the Closing shall not have occurred on

the other parties hereto, provided that no such notice of termination shall be
effective if at the time of such purported termination, Comcast is in material
breach of any of its obligations contained herein or in the Comcast/BTH
Agreement; or (e) if the Closing shall not have occurred on or prior to June 30,
1999, by the Jones Entities upon written notice of such termination to Comcast

breach of any of its obligations contained herein or in the Agreement and
Amendment No. 1 to Shareholders Agreement of even date herewith. This Agreement
and the rights and obligations of the parties hereunder shall cease upon any
termination pursuant to this Section; provided that (x) the provisions of this
Section and Section 2(b), 12(b) and 13 shall survive any termination of this
Agreement and (y) nothing herein shall relieve any party from any liability for
any prior breach of this Agreement.

                                PLEDGE AGREEMENT


         This PLEDGE AGREEMENT is entered into as of the 12 day of August 1998,
by and among Glenn R. Jones ("Jones"), Jones International, Ltd.
("International") and Comcast Corporation ("Comcast").


                  WHEREAS, Comcast, Jones, International, Glenn Jones Grantor
Business Trust, Jones International Grantor Business Trust, Jones Space Segment,
Inc., Jones Global Group, Inc., Jones Interdigital, Inc., and Jones
Entertainment Group, Ltd. have entered into that certain Agreement, dated as of
August __, 1998 (the "Jones/Comcast Agreement");

                  WHEREAS, Section 2 of the Jones/Comcast agreement provides for
Comcast to deposit $50,000,000 with International (the "Initial Consideration");

                  WHEREAS, Section 2 of the Jones/Comcast Agreement further
provides that under certain circumstances described therein, the Jones Entities,
as defined therein, are obligated to repay the Initial Consideration to Comcast
plus interest as described in such Section 2 (the "Secured Obligations");

                  WHEREAS, Comcast's obligation to deposit the Initial
Consideration with International is conditioned upon Jones and International
pledging 2,000,000 shares (the "Class A Stock") of Class A Common Stock, par
value $.01 per share, of Jones Intercable, Inc. (the "Company") with Comcast to
secure the Secured Obligations; and

                  WHEREAS, contemporaneously with the execution and delivery
hereof Comcast is depositing the Initial Consideration with International;

                  THEREFORE, in consideration of the mutual covenants contained
herein and intending to be legally bound hereby, the parties agree as follows.

                  1. The Security Interest. In order to secure the performance
of the Secured Obligations in accordance with the terms thereof,

                  (a) Jones and International each hereby assign and pledge to
Comcast and grant to Comcast a security interest in the Class A Shares, and all
of their rights and privileges with respect to the Class A Shares, and all
income and profits thereon (other than dividends paid by the Company in respect
of the Class A Shares prior to any exercise by Comcast of its remedies
hereunder, which will be paid over to Jones and International as provided in
Section 4) and all proceeds of the foregoing, and any and all property referred
to in Section 1(b) (the "Collateral").

                  (b) In the event any change in the Company's capital stock
shall occur, Jones and International will immediately pledge with Comcast any
securities (and any share certificates or other instruments evidencing such
securities) issued by the Company in respect of the Class A Shares, and all
income and profits thereon (other than dividends paid by the Company in respect
of the Class A Shares prior to any exercise by Comcast of its remedies
hereunder), as additional security for the Secured Obligations. All such
securities, share certificates, instruments and other property constitute
Collateral and are subject to all provisions of this Agreement.

                  (c) The Security Interest is granted as security only and
shall not subject Comcast to, or transfer or in any way affect or modify, any
obligation or liability of Jones and International with respect to any of the
Collateral or any transaction in connection therewith.

                  (d) In the event Jones and International fail to perform any
Secured Obligation, Comcast shall be entitled to exercise all rights of a
secured party under the Uniform Commercial Code (whether or not in effect in the
jurisdiction where the rights are exercised) and such other rights as may
otherwise be provided to a secured party under applicable law.

                  2. Delivery of Collateral. All certificates representing the
Class A Shares (or securities described in Section 1(b)) delivered to Comcast by
Jones and International pursuant hereto shall be in suitable form for transfer
by delivery, or shall be accompanied by duly executed instruments of transfer or
assignment in blank, with signatures appropriately guaranteed, and accompanied
by any required transfer tax stamps, all in form and substance satisfactory to
Comcast.
<PAGE>

                  3. Further Assurances. (a) Jones and International agrees that
they will, at Comcast's expense and in such manner and form as Comcast may
reasonably require, execute, deliver, file and record any financing statement,
specific assignment or other paper and take any other action that may be
necessary or desirable that Comcast may request, in order to create, preserve,
perfect or validate the Security Interest or to enable Comcast to exercise and
enforce its rights hereunder with respect to any of the Collateral. To the
extent permitted by applicable law, Jones and International hereby authorize
Comcast to execute and file, in the name of Jones and International or
otherwise, Uniform Commercial Code financing statements (which may be carbon,
photographic, photostatic or other reproductions of this Pledge Agreement or of
a financing statement relating to this Pledge Agreement) which Comcast in its
reasonable discretion may deem necessary or appropriate to further perfect the
Security Interest.

                  (b) Jones and International agree that they will not change
(i) their name, identity or structure in any manner or (ii) the location of
their chief executive office or domicile unless they shall have given Comcast
not less than 30 days' prior notice thereof.

                  (c) In connection with an exercise of rights pursuant to
Section 1(d), Comcast may cause any or all of the Class A Shares to be
transferred of record into the name of Comcast or its designee. After notice
thereof, Jones and International will promptly give to Comcast (or its designee)
copies of any notices or other communications received by them with respect to
the Class A Shares registered in the name of Jones and International, and
Comcast will promptly give Jones and International copies of any notices and
communications received by Comcast with respect to any Class A Shares registered
in the name of Comcast.

                  4. Right to Vote and Receive Dividends on Collateral. (a)
Until such time (if ever) that Comcast shall have exercised, pursuant to Section
1(d), any of its remedies in respect of the Collateral, Jones and International
shall retain all voting rights with respect to the Class A Shares and shall have
the right to receive all dividends paid by the Company in respect of the
Collateral and Comcast shall take all such action as Jones and International may
deem necessary or appropriate to give effect to such right. All such dividends
which are received by Comcast shall be received in trust for the benefit of
Jones and International and shall promptly be paid over to Jones and
International.

                  (b) In the event Comcast exercises, pursuant to Section 1(d),
any of its remedies in respect of the Collateral, Comcast shall thereafter be
entitled to receive all dividends paid by the Company in respect of the
Collateral.

                  5. Limitation on Duty of Comcast in Respect of Collateral.
Beyond the exercise of reasonable care in the custody thereof, Comcast shall
have no duty as to any Collateral in its possession or control or in the
possession or control of any agent or bailee or any income thereon or as to the
preservation of rights against prior parties or any other rights pertaining
thereto. Comcast shall be deemed to have exercised reasonable care in the
custody and preservation of the Collateral in its possession if the Collateral
is accorded treatment substantially equal to that which it accords its own
property, and shall not be liable or responsible for any loss or damage to any
of the Collateral, or for any diminution in the value thereof, by reason of the
act or omission of any agent or bailee selected by Comcast in good faith.

                  6. Termination of Security Interest; Release of Collateral.
The Security Interest granted hereunder shall terminate, and all rights to the
Collateral shall revert to Jones and International at such time as the Jones
Entities shall have no further obligation to repay the Initial Consideration.
Upon any such termination of the Security Interests or release of Collateral,
Comcast will deliver the Collateral to Jones and International and will execute
and deliver to Jones and International such documents as Jones and International
shall reasonably request to evidence the termination of the Security Interest or
the release of such Collateral, as the case may be.

                                  KNOWLEDGE TV
                               AFFILIATE AGREEMENT


                  THIS AGREEMENT is made as of the ___ day of ___________, 199_,
by and between KNOWLEDGE TV, INC., a Colorado corporation ("KTV"), and COMCAST
PROGRAMMING, a division of COMCAST CORPORATION, a Pennsylvania corporation
("Affiliate"), whose address is 1500 Market Street, Philadelphia, PA. 19102.



IN CONSIDERATION OF THE MUTUAL COVENANTS, STIPULATIONS AND REPRESENTATIONS
CONTAINED HEREIN, THE PARTIES HERETO AGREE AS FOLLOWS:

1.       GRANT OF LICENSE

         Subject to the terms and conditions of this Agreement, KTV hereby
         grants to Affiliate the non-exclusive license to distribute the
         "Knowledge TV" service (the "Service") within any operating area within
         the United States of any (i) cable, satellite master antenna television
         system(s) ("SMATV") or multichannel multipoint distribution system(s)
         of which Affiliate owns now or hereafter no less than 50% or of which
         Affiliate owns now or hereafter no less than 20% and over which
         Affiliate has management control including the authority to make
         programming decisions with respect to the applicable system, and (ii)
         any SMATV system that is operated by a party other than Affiliate in
         the operating area of any cable system of Affiliate or an area
         contiguous thereto, all as listed on the attached Exhibit A, as such
         list may be amended from time to time (the "System(s)"). Affiliate
         shall give prior written notice to KTV of the addition of a System to
         Exhibit A.

2.       TERM AND TERMINATION

         (a)  The term of this  Agreement  shall  commence on the date hereof 
         and shall  extend for a period of five (5) years plus ninety (90) days
         from the date hereof.

         (b) Except as otherwise provided herein, neither Affiliate nor KTV may
         terminate this Agreement except upon sixty (60) days prior written
         notice and then only if the other has made a material misrepresentation
         herein or breaches any of its material obligations hereunder and such
         misrepresentation or breach (which shall be specified in such notice)
         is not cured within sixty (60) days of such notice, or the defaulting
         party has not undertaken within such sixty (60) day period and is not
         diligently pursuing actions to cure such misrepresentation or breach.

         (c) Affiliate acknowledges and agrees that its obligations hereunder
         with respect to the distribution of the Service are of a special,
         unique and extraordinary character and that such distribution has a
         unique and peculiar value, the loss of which cannot be adequately or
         reasonably compensated by damages in an action at law, and that
         Affiliate's failure to perform its obligations hereunder with respect
         to the distribution of the Service shall cause KTV irreparable injury
         and damage. In acknowledgment thereof, Affiliate hereby agrees that, in
         addition to any and all other rights it may have at law or in equity,
         including its termination right set forth above, KTV shall be entitled
         to bring an action for specific performance of the terms of this
         Agreement in the event of any breach thereof by Affiliate.

3.       CONTENT OF SERVICE

         (a) KTV shall have the exclusive authority to determine the content and
         format of the Service, and the selection, scheduling, substitution and
         withdrawal of any program or advertisement shall remain within the sole
         discretion of KTV. Notwithstanding the foregoing, the Service shall
         consist of educational informational materials and programming which
         endeavors to expose the viewer to the activities one might find in a
         school, on a campus, or in other learning environments including but
         not limited to, educational, instructional and informational
         programming and, in addition, such programming as might relate to or
         evolve from schools, campuses or other learning environments including
         bookstores, field trips, laboratories, observatories, libraries and
         trips or outings related to the foregoing, as well as marketing and
         sales activities relating to the foregoing; provided, however, that
         such marketing activities shall not include the direct on-air marketing
         and/or sale of goods or products (excluding materials, books, tapes and
         other items directly relating to any of the educational programming on
         the Service), except as set forth below in this Section 3(a). The
         Service currently contains no more than thirty-five (35) hours in the
         aggregate of infomercial and/or home shopping programming each week.
         KTV shall have the right to increase such infomercial and/or home
         shopping programming at any time during the term of this Agreement;
         provided, however, that if the number of hours of infomercial and/or
         home shopping programming in the Service exceeds thirty-five (35) hours
         each week, Affiliate shall be entitled, at its option, to preempt any
         of the hours of infomercial and/or home shopping programming in excess
         of thirty-five (35) each week; and provided further, however, that any
         infomercial and/or home shopping programming will only be aired by KTV
         during the hours of Midnight to 6:00 a.m., Eastern time, Monday through
         Sunday and during the hours of 3:00 p.m. to 6:00 p.m., Eastern time,
         Saturday and Sunday, such times to be adjusted to reflect comparable
         periods in other time zones in the event that the Service, in the
         future, supplies other than a single satellite feed. Except as set
         forth herein, Affiliate shall distribute the Service without addition,
         deletion, alteration, editing or amendment, including any copyright
         notices, credits and similar notices, trademarks or trade names
         contained therein.

         (b) KTV does not currently make available to any affiliates any local
         advertising time in the Service. However, if during the term of this
         Agreement, KTV makes any such local advertising avails available to any
         distributor of the Service, it will offer at least the same number and
         type of local advertising avails to Affiliate. KTV will not have more
         than twelve (12) minutes during any hour of national advertising time
         in the Service at any time during the term of this Agreement.

4.       RATES AND PAYMENTS

         (a) For those Systems listed on Exhibit A attached hereto, as the same
         may be amended, on or before the forty-fifth (45th) day following each
         month throughout the term of this Agreement, Affiliate shall pay to KTV
         for each Subscriber of such System during the preceding month, at the
         address specified by KTV, license fees in an amount calculated in
         accordance with the attached Exhibit B.

         (b) KTV's failure, for any reason, to send an invoice for a particular
         monthly payment shall not relieve Affiliate of its obligation to make
         any payment in a timely manner consistent with the terms of this
         Agreement. Past due payments may, at KTV's option, bear interest at a
         rate equal to the lesser of (i) one percent (1%) per month or (ii) the
         maximum legal rate permitted under law, and Affiliate shall be liable
         for all reasonable costs and expenses (including, without limitation,
         reasonable court costs and attorneys' fees) incurred by KTV in
         collecting any past due payments.

         (c) For purposes of this Agreement, the term "Subscriber" shall mean
         (i) each residential customer and commercial or business establishment
         (including any restaurant, barbershop, lounge, tavern, social, athletic
         or country club, bar, business office, sales office, store or shop)
         receiving and separately paying for any level of cable television
         service which includes the Service from each System, and (ii) the
         number of basic equivalent subscribers computed by dividing the monthly
         revenue for cable television service paid by bulk accounts (such as
         apartment buildings, cooperatives, condominiums, mobile home parks,
         hotels, and motels) of each System for cable television service up to
         and including the level of service that includes the Service by the
         standard residential rate of that System for cable television service
         up to and including the level of service that includes the Service;
         provided, however, that the term "Subscriber" shall not include persons
         who do not pay any monies to Affiliate to receive the level of service
         on which the Service is carried (which shall be limited to full-time
         employees of Affiliate or of cable system operators located within a
         System's DMA, schools, libraries, government buildings and offices and
         any other complimentary service which is required by a System's
         franchise ordinance, grant, license or other authorizing operating
         agreement).

         (d) Accompanying each payment during the term of this Agreement,
         Affiliate shall provide to KTV a true and complete monthly report,
         prepared by the chief financial officer of Affiliate or his/her
         authorized designee specifying for each System the average number of
         Subscribers of each System during the subject payment period (computed
         by dividing the sum of the number of Subscribers on the first and last
         day of the payment period by two (2)) and certifying the accuracy of
         such information and containing such other information as may be
         reasonably required by KTV for accurate billing purposes, subject to
         applicable law.

                                      -3-

         (e) Affiliate agrees to keep and maintain complete and accurate books
         and records of matters relating to this Agreement. Affiliate grants
         KTV, itself or through an independent audit service selected by KTV,
         the right, during regular business hours, at KTV's expense, to inspect,
         make copies and otherwise audit such books and records at Affiliate's
         offices upon fifteen (15) days' prior written notice from KTV. KTV's
         right to perform such audit shall be limited to once in any twelve (12)
         month period during the term of this Agreement and shall be limited to
         an audit with respect to amounts paid in the current calendar year and
         prior calendar year. Throughout such audit, KTV's auditors or its
         representatives shall discuss with Affiliate's controller, or his
         designee, audit methodology as well as a reasonable estimate of any
         additional payments which KTV believes may be due. If, as a result of
         such audit, it is determined that Affiliate's payments to KTV under
         this Agreement were less than what they should have been, Affiliate
         shall pay to KTV, upon demand by KTV, the difference between
         Affiliate's actual payments to KTV and the undisputed amounts Affiliate
         should have paid to KTV hereunder; provided, however, that KTV shall,
         upon request by Affiliate, make available copies of work papers,
         analyses and other supporting documentation used to calculate any such
         difference. If, as a result of such audit, it is determined that
         Affiliate's payments to KTV under this Agreement were greater than what
         they should have been, Affiliate may elect to receive a cash refund
         from KTV of such overpayment or may elect to have the amount of such
         overpayment credited against future license fees that may be owed to
         KTV under this Agreement. If KTV audits Affiliate's books hereunder,
         KTV must make any claim against Affiliate within three (3) months after
         KTV completes such audit. If the claim is not made within such three
         (3) month period, KTV will be deemed to have waived its right to
         collect any shortfalls from Affiliate for the period(s) audited. Both
         parties shall endeavor to resolve any claim hereunder in a timely
         manner.

5.       DELIVERY AND DISTRIBUTION

         (a) During the term of this Agreement, each of the Systems shall offer
         the Service on such level, and as part of such package, of cable
         television service as Affiliate may elect; provided, however, that
         Affiliate may not distribute the Service (i) on a level or as part of a
         package of cable television service that has a Penetration (as
         hereinafter defined) of less than ten percent (10%); or (ii) as a stand
         alone a la carte service, unless the Service is also carried on a tier
         with at least three (3) other national cable television services; or
         (iii) as part of a package of cable television services that includes
         pay or premium services, such as HBO, Showtime or other similar
         services. For purposes of this Agreement, the term "Penetration" means
         the ratio of the number of Subscribers in any System receiving and
         paying for the level or package of cable television service that
         includes the Service to the total number of basic subscribers of the
         System. Affiliate shall designate one (1) channel on each System for
         the carriage of the Service prior to the commencement of the delivery
         of the Service on such System. Affiliate may change, from time to time,
         the channel designation on which the Service is carried; provided,
         however, that Affiliate shall use commercially reasonable efforts to
         give KTV written notice of the change and the new channel designation
         at least thirty (30) days prior to the effective date of such change.

         (b) On or before forty-five (45) days after the date of this Agreement
         (the "New System Launch Date"), Affiliate shall launch the Service in
         systems that are not currently distributing the Service and which are
         located in one or more of the markets identified on Exhibit C attached
         hereto, which systems shall represent at least 500,000 Subscribers. If
         Affiliate does not launch the Service on Systems representing at least
         500,000 Subscribers as of the New System Launch Date, Affiliate shall
         have until ninety (90) days after the date of this Agreement to cure
         such default without any liability or obligation of any kind to KTV.

         (c) Each System shall distribute the Service on a full time basis at
         all times during the term of this Agreement at the hours it is
         initially transmitted by KTV.

         (d) Affiliate shall not delete the Service from any System or delete
         any System from Exhibit A during the term of this Agreement; provided,
         however, that in the event Affiliate sells a System to an unaffiliated
         third party, Affiliate shall be relieved of all of its obligations with
         respect to such System for all periods after the date of sale of such
         System. Notwithstanding the foregoing, at no time during the term of
         this Agreement, commencing from and after the New System Launch Date,
         shall the number of Subscribers receiving the Service be less than
         500,000 (the "Minimum Distribution Commitment").

                                      -4-
<PAGE>

         (e) KTV will transmit the Service by means of domestic communications
         satellite Galaxy V, Transponder 21. Affiliate shall, at its own
         expense, obtain and install such earth station receivers and other
         equipment as shall be necessary to receive, descramble (if necessary)
         and transmit and deliver to Subscribers receiving the Service the
         signals comprising the Service. In the event KTV decides to change the
         transmission of the Service to another domestic communications
         satellite or change its scrambling or transmission technology, KTV
         shall notify Affiliate at least sixty (60) days prior to the effective
         date of such change. If it reasonably appears that as a result of such
         proposed change Affiliate will incur the expense of additional
         equipment in order to continue to receive or decode the Service,
         Affiliate will be entitled to terminate this Agreement with respect to
         all affected Systems as of the effective date of such change; provided,
         however, that this termination right shall not apply if (i) KTV agrees
         to reimburse such Systems for its pro rata share (based on the number
         of signals to be received by any System from such new satellite) of the
         cost of purchasing and installing equipment reasonably necessary for
         such Systems to receive the Service as the result of any such change;
         (ii) physical space exists at the then-existing earth station sites to
         accommodate the necessary equipment; and (iii) current zoning and other
         restrictions permit such additional equipment. KTV shall provide a high
         quality signal for provision of the Service and shall use commercially
         reasonable efforts to maintain such high quality signal. Affiliate
         shall use commercially reasonable efforts to maintain the high quality
         signal provided by KTV.

         (f) Subject to then existing law, Affiliate shall not itself, and shall
         not expressly authorize others to, copy, tape or otherwise reproduce
         any part of the Service without KTV's prior written authorization, and
         shall take reasonable and practical security measures to prevent the
         unauthorized copying or taping by others; provided, however, that
         nothing herein shall prohibit Affiliate from assisting its residential
         subscribers in connecting video cassette recorders to record the
         Service. Affiliate shall not distribute or exhibit, and shall not
         expressly authorize or license or knowingly permit the distribution or
         exhibition of, the Service by any means or device, whether now known or
         hereafter devised, other than through the Systems now or hereafter
         listed in Exhibit A hereto and in accordance with the terms of this
         Agreement.

6.       PROMOTION AND RESEARCH

         (a) Affiliate shall use commercially reasonable efforts, as determined
         in its best business judgment, to promote, market and sell the Service
         to Subscribers and to the general public within the Operating Area of
         each System. Advertising, promotional, marketing and/or sales materials
         concerning the Service which are provided to Affiliate by KTV, if used
         by Affiliate, shall be used without any alteration, deletion, addition
         or any other change, unless such changes are approved by KTV prior to
         use by Affiliate.

         (b) At KTV's request, each System shall use commercially reasonable
         efforts in its business judgment to provide KTV with data regarding the
         marketing and promotion of the Service by Affiliate. Subject to
         applicable federal, state and local law (including the franchises, if
         any, pursuant to which the Systems are operated), Affiliate also agrees
         to render such other assistance to KTV as KTV may request and which
         Affiliate may reasonably provide in its business judgment in connection
         with any marketing test, survey, poll or other research which KTV may
         undertake in connection with the Service. KTV shall treat as
         confidential any data or information which KTV receives from Affiliate,
         and shall not utilize any such data or information except in connection
         with such research.

         shall be transferred to Affiliate. Affiliate's use of the Marks shall
         be limited to the advertising and promotion of its carriage of the
         Service over the Systems pursuant to this Agreement; provided, however,
         that Affiliate may request that KTV allow it to use the Marks in other
         manners, and KTV agrees not to unreasonably withhold its consent to
         reasonable business uses of the Marks requested by Affiliate. KTV shall
         provide Affiliate with samples of the Marks which Affiliate shall use
         in their entirety (including all service mark and trademark notices)
         whenever the Marks are used by Affiliate.

         (b) KTV acknowledges that the names "Comcast", "Comcast Cable
         Communications, Inc.", "Comcast Cablevision" and the concentric "C"
         mark are the exclusive property of Affiliate and/or its affiliated
         entities, and that KTV has not and will not acquire any proprietary
         rights therein by reason of this Agreement. Any use of such names or
         marks by KTV shall be subject to Affiliate's prior written consent.

         (b) Affiliate represents and warrants to KTV that (i) Affiliate is a

         under the laws of the Commonwealth of Pennsylvania; (ii) Affiliate has
         the corporate power and authority to enter into this Agreement and to

         (iv) Affiliate is under no contractual or other legal obligation which
         in any way interferes with its ability to fully, promptly and
         completely perform hereunder.

         (c) Affiliate and KTV shall each indemnify, defend and forever hold
         harmless the other, the other's affiliated companies and their
         respective officers, directors, employees, partners and agents from all

         claimed breach by it of any representation or warranty or any of its
         obligations pursuant to this Agreement. KTV will credit Affiliate for
         any continuous interruption of Service caused by KTV of twenty-four
         (24) hours or longer. The amount so credited shall be an amount equal
         to that portion of the monthly license fees applicable to the period
         during which the Service was interrupted. KTV's liability for damages
         arising out of its inability or failure to deliver the Service shall be
         limited to the license fee credits set forth in the preceding sentence.

         (d) With respect to music performance rights, KTV agrees that it will
         use its commercially reasonable efforts, at its expense, to secure
         additional appropriate licenses, authorities or other grants of right
         regarding music performance rights related to the exhibition and
         distribution of the Service by KTV, Affiliate and/or the Systems
         distributing the Service which KTV does not currently possess, and will
         indemnify and hold harmless Affiliate from and against any claims,
         damages, liabilities, costs and expenses arising from music performance
         rights related to the exhibition and distribution of the Service by
         KTV, Affiliate and/or the Systems distributing the Service.

         (e) In connection with any indemnification provided for in this Section
         9, each party shall so indemnify the other only if such other party
         claiming indemnification shall give the indemnifying party prompt
         notice of any claim or litigation to which its indemnification applies;
         it being agreed that the indemnifying party shall have the right to
         assume the full defense of any or all claims or litigation to which its
         indemnity applies and that the indemnified party will cooperate fully
         (at the cost of the indemnifying party) with the indemnifying party in
         such defense and in the settlement of such claims or litigation, and
         the indemnified party shall make no compromise or settlement of any
         such claim without the prior written consent of the indemnifying party.
         The settlement of any claim without the prior written consent of the
         indemnifying party shall release the indemnifying party from its
         obligations hereunder with respect to such claim or action so settled.

         (f) Except as herein provided, neither Affiliate nor KTV shall have any
         rights against the other party hereto for the non-operation of
         facilities or the non-furnishing of the Service if such non-operation
         or non-furnishing is due to an act of God; inevitable accident; fire;
         lockout; flood; tornado; hurricane; strike; or other labor dispute;
         riot or civil commotion; earthquake; war; act of government or
         governmental instrumentality (whether federal, state or local); failure
         of performance by a common carrier; failure in whole or in part of
         technical facilities; or other cause (financial inability excepted)
         beyond such party's reasonable control. In the event of non-operation
         or non-furnishing of the Service for a period of ten (10) consecutive
         days, Affiliate shall have the right to insert programming of its
         choice on the channel otherwise identified with the Service until such
         time as the Service is fully operational again. Credit will be given to
         Affiliate, however, on the portion of the Service which is affected by
         an interruption during any month equal to the product of (i) the
         license fees which would be due for such month, calculated in
         accordance with Section 4 hereof, assuming no interruption of Service
         during such month, multiplied by (ii) a fraction, the numerator of
         which is the total number of hours of interruption of the Service
         during such month and the denominator of which is the total number of
         hours of the Service which would have been provided during such month
         absent such interruption(s). In the event of non-operation or
         non-furnishing of the Service for a period of fifteen (15) or more
         consecutive days, or thirty (30) days out of any ninety (90) day
         period, Affiliate may terminate this Agreement by delivery of written
         notice thereof to KTV without any further obligation or liability on
         the part of KTV or Affiliate.

         (g) The representations, warranties and indemnities contained in this
         Section 9 shall continue throughout the term of this Agreement and the
         indemnities shall survive the expiration or termination of this
         Agreement.

10.      CONFIDENTIALITY

         (a) Neither Affiliate nor KTV shall disclose to any third party (other
         than its respective officers, directors, employees, auditors and
         attorneys each of whom shall agree to be bound by the provisions of
         this Section 10 and whose compliance herewith shall be the legal
         obligation of the disclosing party) any information with respect to the
         terms and provisions of this Agreement, including by way of press
         release(s), and KTV shall not disclose any information obtained in any
         inspection and/or audit of Affiliate's books and records, except: (i)
         to the extent necessary to comply with law or legal reporting or
         disclosure requirements, including those relating to the public or
         private offering of securities, or the valid order of an administrative
         agency or a court of competent jurisdiction, in which event the party
         making such disclosure shall so notify the other as promptly as
         practicable (and, if possible, prior to making such disclosure) and
         shall seek confidential treatment of such information; (ii) as part of
         its normal reporting or review procedure to its parent company, its
         auditors and its attorneys; provided, however, that such parent
         company, auditors and attorneys agree to be bound by the provisions of
         this Section 10; (iii) in order to enforce its rights pursuant to this
         Agreement; and (iv) if mutually agreed by Affiliate and KTV in advance
         and in writing.

         (b) This Section 10 shall survive the termination or expiration of this
         Agreement.

11.      GENERAL

         (a) This Agreement shall inure to the benefit of and be binding upon
         the parties hereto and their respective successors and assigns.
         Notwithstanding the foregoing, this Agreement may not be assigned by
         either party without the prior written consent of the other party,
         which consent shall not be unreasonably withheld, except that upon 30
         days' prior notice to the other party, either party may assign this
         Agreement to any entity controlled by, controlling, or under common
         control with such party, or to an entity acquiring all or substantially
         all of the assets of such party, whether by acquisition, stock
         issuance, trade, merger or other means.

         (b) Neither Affiliate nor KTV shall be, or hold itself out as, the
         agent of the other under this Agreement. No subscriber of Affiliate
         shall be deemed to have any privity of contract or direct contractual
         or other relationship with KTV by virtue of this Agreement or KTV's
         delivery of the Service to Affiliate hereunder. Likewise, no supplier
         of advertising or programming or anything else included in the Service
         by KTV shall be deemed to have any privity of contract or direct
         contractual or other relationship with Affiliate by virtue of this
         Agreement or Affiliate's carriage of the Service hereunder. Nothing
         contained herein shall be deemed to create, and the parties do not
         intend to create, any relationship of partners, joint venturers or
         agents, as between Affiliate and KTV, and neither party is authorized
         to or shall act toward third parties or the public in any manner which
         would indicate any such relationship with the other. KTV disclaims any
         present or future right, interest or estate in or to the transmission
         facilities of Affiliate or the parent, subsidiaries, partnerships or
         joint venturers controlling the Systems on which the programming
         signals delivered by Affiliate are transmitted, such disclaimer being
         to acknowledge that neither Affiliate nor the transmission facilities
         of the Systems (and the owners thereof) are common carriers.

         (c) Except for the Original KTV Agreement (as hereinafter defined),
         this Agreement contains the entire understanding of the parties and
         supersedes all prior understandings of the parties relating to the
         subject matter herein. This Agreement may not be modified except in
         writing executed by all parties hereto. Any waiver must be in writing
         and signed by the party whose rights are being waived and no waiver by
         either Affiliate or KTV of any breach of any provision hereof shall be
         or be deemed to be a waiver of any preceding or subsequent breach of
         the same or any other provision of this Agreement.

         (d) This Agreement and all collateral matters shall be construed in
         accordance with the internal laws of the State of Colorado applicable
         to agreements fully made and to be performed therein, irrespective of
         the place of actual execution or performance.

         (e) The invalidity or unenforceability of any provision of this
         Agreement shall in no way affect the validity or enforceability of any
         other provision of this Agreement.

                                      -8-
<PAGE>

         (f) KTV and Affiliate each acknowledge that this Agreement was fully
         negotiated by the parties and, therefore, no provision of this
         Agreement shall be interpreted against any party because such party or
         its legal representative drafted such provision.

         (g) The provisions of this Agreement are for the exclusive benefit of
         the parties hereto and their permitted assigns, and no third party
         shall be a beneficiary of, or have any rights by virtue of, this
         Agreement.

         (h) The titles and headings of the sections in this Agreement are for
         convenience only and shall not in any way affect the interpretation of
         this Agreement.

         (i) If at any time during the term of this Agreement, KTV offers any
         other distributor of the Service terms and conditions with respect to
         the following matters: exclusivity, distribution to alternate
         technologies, tiering, packaging, and/or a la carte carriage (the
         "Non-Economic Terms"), which are more favorable than the terms set
         forth herein, KTV shall offer to Affiliate such more favorable terms
         and conditions with respect to the Non-Economic Terms for such period
         of time as the same are available to the other third party distributor;
         provided, however, that Affiliate must also accept those terms and
         conditions of such other distributor's agreement as were material
         inducements to KTV's willingness to offer such more favorable terms to
         the other third party distributor to the extent such terms and
         conditions are not unique to such other distributor and Affiliate can
         reasonably comply with such terms and conditions.

                  (ii) Within ten (10) business days after receiving Affiliate's
         request, KTV shall provide Affiliate with a certificate signed by an
         authorized officer of KTV stating that KTV has complies with the
         conditions of this Section.

         (j) As between KTV and Affiliate, Affiliate shall be responsible for
         all taxes levied upon Affiliate or related to the existence or
         operation of the Systems or to its handling and delivery of the Service
         from its Systems' headends to Subscribers. KTV shall be responsible for
         all taxes levied with respect to producing, distributing, licensing and
         transmitting the Service to such headends.

         (k) Except with respect to closed captioning and second audio programs
         (which uses Affiliate agrees shall be reserved to KTV throughout the
         Term of this Agreement), KTV agrees that signal distribution beyond
         traditional television video and audio, including but not limited to
         the use of Vertical Blanking Interval ("VBI"), is not essential to, nor
         a part of, the transmission of the Service and, thus, except for the
         rights reserved to KTV herein, all rights in and to signal distribution
         beyond traditional television video and audio, including but not
         limited to the use of the VBI, are retained by and reserved to
         Affiliate, and nothing herein shall preclude Affiliate from exercising
         and exploiting such rights exclusively by means and in any locations
         concurrently herewith freely and without restrictions.

         (l) The obligations of Affiliate under this Agreement with respect to
         the launch and distribution of the Service are in addition to the
         obligations of Affiliate under that certain Affiliate Agreement dated
         as of January 1, 1997 between KTV (f/k/a Mind Extension University,
         Inc.) and Affiliate (the "Original KTV Agreement"). The terms and
         conditions of the Original KTV Agreement shall govern the distribution
         of the Service on Systems where the Service is launched pursuant to the
         terms of such agreement, and the terms and conditions of this Agreement
         shall govern the distribution of the Service on Systems where the
         Service is launched pursuant to the terms of this Agreement.

2.       TERM AND TERMINATION

         (a)  The term of this  Agreement  shall  commence on the date hereof 
         and shall  extend for a period of five (5) years plus ninety (90) days
         from the date hereof.

         (b) Except as otherwise provided herein, neither Affiliate nor 
         G.A.C may terminate this Agreement except upon ninety (90) days 
         prior written notice and then only if the other has made a material
         misrepresentation herein or breaches any of its material obligations 
         hereunder and such misrepresentation or breach (which shall be 
         specified in such notice) is not cured within ninety (90) days of such
         notice, or the defaulting party has not undertaken within such ninety
         (90) day period and is not diligently pursuing actions to cure such
         misrepresentation or breach. The parties' right to terminate this 
         Agreement pursuant to this Section 2(b) shall be in addition to any 
         right or remedy which either party may have in law or equity.

3.       CONTENT OF SERVICE

         (a) G.A.C shall have the exclusive authority to determine the
         content and format of the Service, and the selection, scheduling,
         substitution and withdrawal of any program or advertisement shall
         remain within the sole discretion of G.A.C. Notwithstanding the
         foregoing, the Service shall consist of a twenty-four (24) hour a day,
         satellite-delivered country music television network that features
         current and past country music videos, concerts, information on country
         music artists and occasional short-form programming that focuses on
         both country music and country music's performing artists. Affiliate
         shall distribute the Service without addition, deletion, alteration,
         editing or amendment, including any copyright notices, credits and
         similar notices, trademarks or trade names contained therein.

         (b) G.A.C shall make available to Affiliate not less than four (4)
         minutes of commercial advertising time in each programming hour for use
         by Affiliate in inserting local advertising or promotions. All such
         availabilities shall be at such points in the transmission of the
         Service as G.A.C determines in its sole discretion. G.A.C shall
         signal Affiliate's commercial advertising time by a hidden cue tone.
         Affiliate shall use its reasonable efforts to assure that all
         commercial matter or advertisements it inserts with the Service (i) are
         not offensive in nature; (ii) do not suggest an affiliation between 
         G.A.C or any programming contained in the Service, and third party
         advertisers, and (iii) are compatible with applicable law. Affiliate's
         commercial advertising time shall be fixed, nonrecapturable and
         nonpreemptible, except that under limited circumstances and uniformly
         applied to all affiliates of G.A.C, G.A.C may give thirty (30)
         days' notice to Affiliate preempting Affiliate's specific commercial
         time, provided that G.A.C makes available to Affiliate, within 
         sixty (60) days of such preemption, an equal amount of commercial time
         in a like time period.

                                      -1-
<PAGE>

         (c) The Service shall not contain more than four (4) hours of
         infomercial and/or long form (i.e. longer than two minutes) home
         shopping programming (collectively, "Infomercial Programming"), in any
         day, and any Infomercial Programming so included in the Service shall
         be aired only between the hours of Midnight and 6:00 a.m. Eastern Time.
         Beginning at the earlier of (i) January 1, 2002, (ii) such time as the
         Service is being distributed to at least 20,000,000 Service
         Subscribers, in the aggregate, in the United States, or (iii) the date
         on which any other affiliate of G.A.C has the right to preempt
         Infomercial Programming included in the Service, Affiliate shall be
         entitled, at its option, to preempt up to one hundred percent (100%) of
         the Infomercial Programming included in the Service. In the event of
         any such permitted preemption, Affiliate shall be entitled to insert
         programming of its own choosing into the Service during the periods of
         such preemption; provided, however, that such inserted programming is
         not adult-oriented programming and otherwise meets the standards for
         inserted material set forth in Section 3(b) of this Agreement.

4.       RATES AND PAYMENTS

         (a) For those Systems listed on Exhibit A attached hereto, as the same
         may be amended, on or before the forty-fifth (45th) day following each
         month throughout the term of this Agreement, Affiliate shall pay to 
         G.A.C for each Service Subscriber of such System during the 
         preceding month, at the address specified by G.A.C, license fees
         in an amount calculated in accordance with the attached Exhibit B.

         (b) G.A.C's failure, for any reason, to send an invoice for a
         particular monthly payment shall not relieve Affiliate of its
         obligation to make any payment in a timely manner consistent with the
         terms of this Agreement. Past due payments may, at G.A.C's option,
         bear interest at a rate equal to the lesser of (i) one percent (1%) per
         month or (ii) the maximum legal rate permitted under law, and Affiliate
         shall be liable for all reasonable costs and expenses (including,
         without limitation, reasonable court costs and attorneys' fees)
         incurred by G.A.C in collecting any past due payments.

         (c) For purposes of this Agreement, the term "Service Subscriber" shall
         mean (i) each residential customer and commercial or business
         establishment (including any restaurant, barbershop, lounge, tavern,
         social, athletic or country club, bar, business office, sales office,
         store or shop) receiving and separately paying for any level of cable
         television service which includes the Service from each System, and
         (ii) the number of basic equivalent subscribers computed by dividing
         the monthly revenue for cable television service paid by bulk accounts
         (such as apartment buildings, cooperatives, condominiums, mobile home
         parks, hotels, and motels) of each System for cable television service
         up to and including the level of service that includes the Service by
         the standard residential rate of that System for cable television
         service up to and including the level of service that includes the
         Service; provided, however, that the term "Service Subscriber" shall
         not include persons who do not pay any monies to Affiliate to receive
         the level of service on which the Service is carried (which shall be
         limited to full-time employees of Affiliate or of cable system
         operators located within a System's DMA, schools, libraries, government
         buildings and offices and any other complimentary service which is
         required by a System's franchise ordinance, grant, license or other
         authorizing operating agreement).

         (d) Accompanying each payment during the term of this Agreement,
         Affiliate shall provide to G.A.C a true and complete monthly 
         report, prepared by the chief financial officer of Affiliate or his/her
         authorized designee specifying for each System the average number of
         Service Subscribers of each System during the subject payment period
         (computed by dividing the sum of the number of Service Subscribers on
         the first and last day of the payment period by two (2)) and certifying
         the accuracy of such information and containing such other information
         as may be reasonably required by G.A.C for accurate billing 
         purposes, subject to applicable law.

                                      -2-

         (e) Affiliate agrees to keep and maintain complete and accurate books
         and records of matters relating to this Agreement. Affiliate grants 
         G.A.C., itself or through an independent audit service selected by 
         G.A.C., the right, during regular business hours, at G.A.C's expense,
         to inspect, make copies and otherwise audit such books and records at
         Affiliate's offices upon fifteen (15) days' prior written notice from
         G.A.C. G.A.C's right to perform such audit shall be limited to
         once in any twelve (12) month period during the term of this Agreement
         and shall be limited to an audit with respect to amounts paid in the
         current calendar year and prior calendar year. Throughout such audit,
         G.A.C's auditors or its representatives shall discuss with
         Affiliate's controller, or his designee, audit methodology as well as a
         reasonable estimate of any additional payments which G.A.C believes
         may be due. If, as a result of such audit, it is determined that
         Affiliate's payments to G.A.C under this Agreement were less than
         what they should have been, Affiliate shall pay to G.A.C, upon 
         demand by G.A.C, the difference between Affiliate's actual 
         payments to G.A.C and the undisputed amounts Affiliate should have 
         paid to G.A.C hereunder; provided, however, that G.A.C shall, 
         upon request by Affiliate, make available copies of work papers,
         analyses and other supporting documentation used to calculate any such
         difference. If, as a result of such audit, it is determined that
         Affiliate's payments to G.A.C under this Agreement were greater
         than what they should have been, Affiliate may elect to receive a cash
         refund from G.A.C of such overpayment or may elect to have the
         amount of such overpayment credited against future license fees that
         may be owed to G.A.C under this Agreement. If G.A.C audits
         Affiliate's books hereunder, G.A.C must make any claim against
         Affiliate within three (3) months after G.A.C completes such audit.
         If the claim is not made within such three (3) month period, G.A.C
         will be deemed to have waived its right to collect any shortfalls from
         Affiliate for the period(s) audited. Both parties shall endeavor to
         resolve any claim hereunder in a timely manner.

5.       DELIVERY AND DISTRIBUTION

         (a) During the term of this Agreement, each of the Systems shall offer
         the Service on such level, and as part of such package, of cable
         television service as Affiliate may elect; provided, however, that
         Affiliate may not distribute the Service (i) as a stand alone a la
         carte service, unless the Service is also carried on a tier with at
         least three (3) other national cable television services; or (ii) as
         part of a package of cable television services that includes pay or
         premium services, such as HBO, Showtime or other similar services; and
         provided further, however, that Affiliate must maintain an aggregate
         Penetration (as hereinafter defined) for the Service on all Systems
         distributing the Service of not less than fifty percent (50%). For
         purposes of this Section 5(a), the term "Penetration" means the ratio
         of the aggregate number of Service Subscribers in all Systems
         distributing the Service, to the total number of basic subscribers of
         those Systems, excluding those subscribers receiving only a "lifeline"
         level of service. Affiliate shall designate one (1) channel on each
         System for the carriage of the Service prior to the commencement of the
         delivery of the Service on such System. Affiliate may change, from time
         to time, the channel designation on which the Service is carried;
         provided, however, that Affiliate shall use commercially reasonable
         efforts to give G.A.C written notice of the change and the new
         channel designation at least thirty (30) days prior to the effective
         date of such change.

         (b) On or before forty-five (45) days after the date of this Agreement,
         (the "New System Launch Date"), Affiliate shall launch the Service in
         systems that are not currently distributing the Service, which systems
         shall represent at least 500,000 Service Subscribers. If Affiliate does
         not launch the Service on Systems representing at least 500,000 Service
         Subscribers as of the New System Launch Date, Affiliate shall have
         until ninety (90) days after the date of this Agreement to cure such
         default without any liability or obligation of any kind to G.A.C.
   
                                   -3-

<PAGE>

         (c) Each System shall distribute the Service on a full time basis at
         all times during the term of this Agreement at the hours it is
         initially transmitted by G.A.C.

         (d) Affiliate shall not delete the Service from any System or delete
         any System from Exhibit A during the term of this Agreement; provided,
         however, that in the event Affiliate sells a System to an unaffiliated
         third party, Affiliate shall be relieved of all of its obligations with
         respect to such System for all periods after the date of sale of such
         System. Notwithstanding the foregoing, at no time during the term of
         this Agreement, commencing from and after the New System Launch Date,
         shall the number of Service Subscribers be less than 500,000 (the
         "Minimum Distribution Requirement").

         (e) G.A.C will transmit the Service to each System by means of
         domestic communications satellite GE American C-3, Transponder 20, and
         at all times at no additional cost to Affiliate. Affiliate shall, at
         its own expense, obtain and install such earth station receivers and
         other equipment as shall be necessary to receive, descramble (if
         necessary) and transmit and deliver to Subscribers receiving the
         Service the signals comprising the Service. In the event G.A.C
         decides to change the transmission of the Service to another domestic
         communications satellite or change its scrambling or transmission
         technology, G.A.C shall notify Affiliate at least sixty (60) days
         prior to the effective date of such change. If it reasonably appears
         that as a result of such proposed change Affiliate will incur the
         expense of additional equipment in order to continue to receive or
         decode the Service, Affiliate will be entitled to terminate this
         Agreement with respect to all affected Systems as of the effective date
         of such change; provided, however, that this termination right shall
         not apply if (i) G.A.C agrees to reimburse such Systems for its pro
         rata share (based on the number of signals to be received by any System
         from such new satellite) of the cost of purchasing and installing
         equipment reasonably necessary for such Systems to receive the Service
         as the result of any such change; (ii) physical space exists at the
         then-existing earth station sites to accommodate the necessary
         equipment; and (iii) current zoning and other restrictions permit such
         additional equipment. G.A.C shall provide a high quality signal for
         provision of the Service and shall use commercially reasonable efforts
         to maintain such high quality signal. Affiliate shall use commercially
         reasonable efforts to maintain the high quality signal provided by 
         G.A.C

         (f) Subject to then existing law, Affiliate shall not itself, and shall
         not expressly authorize others to, copy, tape or otherwise reproduce
         any part of the Service without G.A.C's prior written 
         authorization, and shall take reasonable and practical security 
         measures to prevent the unauthorized copying or taping by others;
         provided, however, that nothing herein shall prohibit Affiliate from
         assisting its residential subscribers in connecting video cassette 
         recorders to record the Service. Affiliate shall not distribute or
         exhibit, and shall not expressly authorize or license or knowingly
         permit the distribution or exhibition of, the Service by any means or
         device, whether now known or hereafter devised, other than through the 
         Systems now or hereafter listed in Exhibit A hereto and in accordance 
         with the terms of this Agreement.

6.       PROMOTION AND RESEARCH

         (a) Affiliate shall use commercially reasonable efforts, as determined
         in its best business judgment, to promote, market and sell the Service
         to subscribers and to the general public within the Operating Area of
         each System. Advertising, promotional, marketing and/or sales materials
         concerning the Service which are provided to Affiliate by G.A.C, if
         used by Affiliate, shall be used without any alteration, deletion,
         addition or any other change, unless such changes are approved by
         G.A.C prior to use by Affiliate.

         (b) At G.A.C's request, each System shall use commercially
         reasonable efforts in its business judgment to provide G.A.C with
         data regarding the marketing and promotion of the Service by Affiliate.
         Subject to applicable federal, state and local law (including the
         franchises, if any, pursuant to which the Systems are operated),
         Affiliate also agrees to render such other assistance to G.A.C as
         G.A.C may request and which Affiliate may reasonably provide in its
         business judgment in connection with any marketing test, survey, poll
         or other research which G.A.C may undertake in connection with the
         Service. G.A.C shall treat as confidential any data or information
         which G.A.C receives from Affiliate, and shall not utilize any such
         data or information except in connection with such research.

7.       NOTICES

          All notices, statements and other communications given hereunder shall
         be in writing and shall be delivered by facsimile transmission,

8.       TRADEMARKS

          (a) All right, title and interest in and to the Service, and all
         materials, formats, computer software or other rights of whatever
         nature related thereto shall remain the property of G.A.C. Further,
         Affiliate acknowledges and agrees that all names, logos, marks,
         copyright notices or designations utilized by G.A.C in connection
         with the Service (the "Marks") are the sole and exclusive property of
         G.A.C and/or its affiliates, and no rights or ownership are
         intended to be or shall be transferred to Affiliate. Affiliate's use of
         the Marks shall be limited to the advertising and promotion of its
         carriage of the Service over the Systems pursuant to this Agreement;
         provided, however, that Affiliate may request that G.A.C allow it
         to use the Marks in other manners, and G.A.C agrees not to
         unreasonably withhold its consent to reasonable business uses of the
         Marks requested by Affiliate. G.A.C shall provide Affiliate with
         samples of the Marks which Affiliate shall use in their entirety
         (including all service mark and trademark notices) whenever the Marks
         are used by Affiliate.

         (b) G.A.C acknowledges that the names "Comcast", "Comcast Cable
         Communications, Inc.", "Comcast Cablevision" and the concentric "C"
         mark are the exclusive property of Affiliate and/or its affiliated

         proprietary rights therein by reason of this Agreement. Any use of 
         such names or marks by G.A.C shall be subject to Affiliate's prior
         written consent.

         and warranty is given with respect to music performance rights, subject

         hereof; and (vii) the license fee rates set forth on Exhibit B attached
         hereto for the years 2003 and 2004 are the standard license fee rates

         affiliate agreement with a cable television operator in the United
         States with an equivalent or greater number of basic cable television
         subscribers as Affiliate.

          (b) Affiliate represents and warrants to G.A.C that (i) Affiliate

         distributing the Service which G.A.C does not currently possess,
         and will indemnify and hold harmless Affiliate from and against any
         claims, damages, liabilities, costs and expenses arising from music

         (e) In connection with any indemnification provided for in this Section
         9, each party shall so indemnify the other only if such other party
         claiming indemnification shall give the indemnifying party prompt
         notice of any claim or litigation to which its indemnification applies;
         it being agreed that the indemnifying party shall have the right to
         assume the full defense of any or all claims or litigation to which its
         indemnity applies and that the indemnified party will cooperate fully
         (at the cost of the indemnifying party) with the indemnifying party in
         such defense and in the settlement of such claims or litigation, and
         the indemnified party shall make no compromise or settlement of any
         such claim without the prior written consent of the indemnifying party.
         The settlement of any claim without the prior written consent of the
         indemnifying party shall release the indemnifying party from its
         obligations hereunder with respect to such claim or action so settled.

          (f) Except as herein provided, neither Affiliate nor G.A.C shall
         have any rights against the other party hereto for the non-operation of
         facilities or the non-furnishing of the Service if such non-operation
         or non-furnishing is due to an act of God; inevitable accident; fire;
         lockout; flood; tornado; hurricane; strike; or other labor dispute;
         riot or civil commotion; earthquake; war; act of government or
         governmental instrumentality (whether federal, state or local); failure
         of performance by a common carrier; failure in whole or in part of
         technical facilities; or other cause (financial inability excepted)
         beyond such party's reasonable control. In the event of non-operation
         or non-furnishing of the Service for a period of ten (10) consecutive
         days, Affiliate shall have the right to insert programming of its
         choice on the channel otherwise identified with the Service until such
         time as the Service is fully operational again. Credit will be given to
         Affiliate, however, on the portion of the Service which is affected by
         an interruption during any month equal to the product of (i) the
         license fees which would be due for such month, calculated in
         accordance with Section 4 hereof, assuming no interruption of Service
         during such month, multiplied by (ii) a fraction, the numerator of
         which is the total number of hours of interruption of the Service
         during such month and the denominator of which is the total number of
         hours of the Service which would have been provided during such month
         absent such interruption(s). In the event of non-operation or
         non-furnishing of the Service for a period of fifteen (15) or more
         consecutive days, or thirty (30) days out of any ninety (90) day
         period, Affiliate may terminate this Agreement by delivery of written
         notice thereof to G.A.C without any further obligation or liability
         on the part of G.A.C or Affiliate.

         (g) The representations, warranties and indemnities contained in this
         Section 9 shall continue throughout the term of this Agreement and the
         indemnities shall survive the expiration or termination of this
         Agreement.

10.      CONFIDENTIALITY

          (a) Neither Affiliate nor G.A.C shall disclose to any third party
         (other than its respective officers, directors, employees, auditors and
         attorneys each of whom shall agree to be bound by the provisions of
         this Section 10 and whose compliance herewith shall be the legal
         obligation of the disclosing party) any information with respect to the
         terms and provisions of this Agreement, including by way of press
         release(s), and G.A.C shall not disclose any information obtained
         in any inspection and/or audit of Affiliate's books and records,
         except: (i) to the extent necessary to comply with law or legal
         reporting or disclosure requirements, including those relating to the
         public or private offering of securities, or the valid order of an
         administrative agency or a court of competent jurisdiction, in which
         event the party making such disclosure shall so notify the other as
         promptly as practicable (and, if possible, prior to making such
         disclosure) and shall seek confidential treatment of such information;
         (ii) as part of its normal reporting or review procedure to its parent
         company, its auditors and its attorneys; provided, however, that such
         parent company, auditors and attorneys agree to be bound by the
         provisions of this Section 10; (iii) in order to enforce its rights
         pursuant to this Agreement; and (iv) if mutually agreed by Affiliate
         and G.A.C in advance and in writing.

         (b) This Section 10 shall survive the termination or expiration of this
         Agreement.

11.      GENERAL

         (a) This Agreement shall inure to the benefit of and be binding upon
         the parties hereto and their respective successors and assigns.
         Notwithstanding the foregoing, this Agreement may not be assigned by
         either party without the prior written consent of the other party,
         which consent shall not be unreasonably withheld, except that upon 30
         days' prior notice to the other party, either party may assign this
         Agreement to any entity controlled by, controlling, or under common
         control with such party, or to an entity acquiring all or substantially
         all of the assets of such party, whether by acquisition, stock
         issuance, trade, merger or other means.

          (b) Neither Affiliate nor G.A.C shall be, or hold itself out as,
         the agent of the other under this Agreement. No subscriber of Affiliate
         shall be deemed to have any privity of contract or direct contractual
         or other relationship with G.A.C by virtue of this Agreement or
         G.A.C's delivery of the Service to Affiliate hereunder. Likewise,
         no supplier of advertising or programming or anything else included in
         the Service by G.A.C shall be deemed to have any privity of
         contract or direct contractual or other relationship with Affiliate by
         virtue of this Agreement or Affiliate's carriage of the Service
         hereunder. Nothing contained herein shall be deemed to create, and the
         parties do not intend to create, any relationship of partners, joint
         venturers or agents, as between Affiliate and G.A.C, and neither
         party is authorized to or shall act toward third parties or the public
         in any manner which would indicate any such relationship with the
         other. G.A.C disclaims any present or future right, interest or
         estate in or to the transmission facilities of Affiliate or the parent,
         subsidiaries, partnerships or joint venturers controlling the Systems
         on which the programming signals delivered by Affiliate are
         transmitted, such disclaimer being to acknowledge that neither
         Affiliate nor the transmission facilities of the Systems (and the
         owners thereof) are common carriers.

                                      -8-

          (c) Except for the Original G.A.C Agreement (as hereinafter
         defined), this Agreement contains the entire understanding of the
         parties and supersedes all prior understandings of the parties relating
         to the subject matter herein. This Agreement may not be modified except
         in writing executed by all parties hereto. Any waiver must be in
         writing and signed by the party whose rights are being waived and no
         waiver by either Affiliate or G.A.C of any breach of any provision
         hereof shall be or be deemed to be a waiver of any preceding or
         subsequent breach of the same or any other provision of this Agreement.

         (d) This Agreement and all collateral matters shall be construed in
         accordance with the internal laws of the State of Colorado applicable
         to agreements fully made and to be performed therein, irrespective of
         the place of actual execution or performance.

         (e) The invalidity or unenforceability of any provision of this
         Agreement shall in no way affect the validity or enforceability of any
         other provision of this Agreement.

         (f) G.A.C and Affiliate each acknowledge that this Agreement was
         fully negotiated by the parties and, therefore, no provision of this
         Agreement shall be interpreted against any party because such party or
         its legal representative drafted such provision.

         (g) The provisions of this Agreement are for the exclusive benefit of
         the parties hereto and their permitted assigns, and no third party
         shall be a beneficiary of, or have any rights by virtue of, this
         Agreement.

         (h) The titles and headings of the sections in this Agreement are for
         convenience only and shall not in any way affect the interpretation of
         this Agreement.

         (i) (i) G.A.C agrees that if, at any time during the term of this
         Agreement, it gives or offers to any third party with an equivalent or
         lesser number of Service Subscribers than Affiliate any non-economic
         term, provision, covenant or consideration (excluding deletion rights)
         which are or is more favorable to such third party than Affiliate is
         receiving hereunder, G.A.C will afford such more favorable
         non-economic term, provision, covenant or consideration to Affiliate,
         on and subject to the same material terms and conditions offered or
         given to such other affiliate.

          (ii) Within ten (10) business days after receiving Affiliate's
         request, G.A.C shall provide Affiliate with a certificate signed by
         an authorized officer of G.A.C stating that G.A.C has complied
         with the conditions of this Section.

          (j) As between G.A.C and Affiliate, Affiliate shall be responsible
         for all taxes levied upon Affiliate or related to the existence or
         operation of the Systems or to its handling and delivery of the Service
         from its Systems' headends to subscribers. G.A.C shall be
         responsible for all taxes levied with respect to producing,
         distributing, licensing and transmitting the Service to such headends.

          (k) Except with respect to closed captioning and second audio programs
         (which uses Affiliate agrees shall be reserved to G.A.C throughout
         the Term of this Agreement), G.A.C agrees that signal distribution
         beyond traditional television video and audio, including but not
         limited to the use of Vertical Blanking Interval ("VBI"), is not
         essential to, nor a part of, the transmission of the Service and, thus,
         except for the rights reserved to G.A.C herein, all rights in and
         to signal distribution beyond traditional television video and audio,
         including but not limited to the use of the VBI, are retained by and
         reserved to Affiliate, and nothing herein shall preclude Affiliate from
         exercising and exploiting such rights exclusively by means and in any
         locations concurrently herewith freely and without restrictions.

          (l) The obligations of Affiliate under this Agreement with respect to
         the launch and distribution of the Service are in addition to the
         obligations of Affiliate under that certain Affiliate Agreement dated
         as of December 10, 1997 between G.A.C and Affiliate (the "Original
         G.A.C Agreement"). The terms and conditions of the Original
         G.A.C Agreement shall govern the distribution of the Service on
         Systems where the Service is launched pursuant to the terms of such
         agreement, and the terms and conditions of this Agreement shall govern
         the distribution of the Service on Systems where the Service is
         launched pursuant to the terms of this Agreement.

         1.4. Amendment to Section 3.5. Effective as of and conditioned upon the
consummation of the transactions contemplated by the Jones/Comcast Agreement.
Section 3.5 of the Shareholders Agreement shall be deleted in its entirety and
the following substituted in lieu thereof:

                                    "3.5 Programming Services. Notwithstanding
                  any other provision in this Agreement to the contrary: (a) The
                  Bell International Group Entities shall have the right to
                  distribute, on a full-time (or, if requested from time to time
                  by Investor, part-time to be extended or restored, as
                  applicable to full time upon Investor's request), daily basis,
                  programming packaged (as opposed to brokered) by, created by
                  or created primarily for a Bell International Group Entity
                  ("Investor Programming") on such number of channels (not to
                  exceed two at any one time) on the Systems as Investor may
                  designate from time to time.

                                    (b) Prior to exercising its distribution
                  right with respect to any programming under this Section 3.5,
                  the relevant Bell International Group Entity (a "Programmer")
                  will present to the Board a reasonably detailed business plan
                  that, among other things, describes (i) the general content of
                  such programming, (ii) the marketing strategy for such
                  programming, including service level (such as basic, tier or a
                  la carte) and (iii) pricing for such service levels. The
                  Investor Programming shall be carried and priced by the
                  Intercable Group Entities on such level or levels of services
                  as such programming is intended to be carried under the
                  business plan for such programming.

                                    (c) Notwithstanding the rights granted
                  pursuant to paragraph (a) above:

                                    (i) the Intercable Group Entities shall not
                  be required to delete from any System any programming acquired
                  from any third-party programmer prior to the expiration of the
                  term of the program carriage agreement with such third-party
                  programmer in order to carry any Investor Programming,

                                    (ii) in the event there is insufficient
                  channel capacity to carry Investor Programming, carriage of
                  such Investor Programming on a System shall be given priority
                  over any third party programming not then carried by such
                  System and over any third party programming then carried by
                  the System at such time as the initial or then current renewal
                  term, as applicable, is scheduled to expire, provided that (x)
                  such priority shall not apply to off-air programming carried
                  by the four major broadcast networks or as mandated by law, or
                  the 20 most widely viewed third party programs as then carried
                  by the System at the time as reported by Cablevision magazine,
                  and (y) in addition to the foregoing requirements, the Company
                  shall use its reasonable best efforts to add Investor
                  Programming to the Systems whenever opportunities to do so
                  arise, and

                                    (iii) Investor shall give the Company at
                  least four months' prior notice of any proposed commencement
                  or termination of use of any channel.

                                    (d) During the Validation Period (as defined
                  herein), the license fee payable by the Intercable Group
                  Entities for any unit of Investor Programming ("New
                  Programming") shall be such license fee as the Programmer
                  establishes in good faith based on its reasonable estimate of
                  the market value of such New Programming. A Programmer shall
                  notify the Company and the Disinterested Directors in writing
                  promptly following the end of the Validation Period whether
                  the Programmer has entered into an agreement providing for (a)
                  the distribution of such New Programming by a cable television
                  operator or other distributor of video programming (a
                  "Distributor") having at least 400,000 subscribers
                  ("Validating Distributor") and (b) the payment of a license
                  fee by such Validating Distributor at a rate equal to or
                  greater than the license fee payable by the Intercable Group
                  Entities ("Validating Programming Agreement"). If no
                  Validating Programming Agreement has been entered into during
                  the Validation Period, the Company or any Disinterested
                  Director may, by written notice given within sixty (60) days
                  after receipt by the Company and the Disinterested Directors
                  of the above-referenced notification, require that such
                  Programmer reduce the license fee payable by the Intercable
                  Group Entities for such New Programming to the greater of (i)
                  a license agreement approved by the Disinterested Directors,
                  (ii) the average license fee charged by the applicable
                  Programmer to all Distributors for such New Programming and
                  (iii) the Agreed Rate in effect at such time. For purposes of
                  this Section 3.5, "Agreed Rate" means, at any time, the rate
                  set forth in the Affiliate Agreement between Mind Extension
                  University, Inc. and the Company dated December 28, 1993, as
                  amended as of June 1, 1994. Thereafter, the license fee
                  payable by the Intercable Group Entities for such New
                  Programming shall be subject to such adjustments as are
                  similar to adjustments in the license fee permitted by the
                  Validating Programming Agreement or, if there is no such
                  agreement in effect, by the programming agreement pursuant to
                  which such New Programming is carried by the largest
                  Distributor serving fewer than 400,000 subscribers. A
                  Programmer may elect at any time to terminate carriage of such
                  unit of New Programming upon not less than ninety days prior
                  written notice to the Company if it does enter into a
                  Validating Programming Agreement during the Validation Period.
                  "Validation Period" shall mean, as to any New Programming, the
                  fifteen (15) month period commencing with the first month with
                  respect to which a license fee is payable by an Intercable
                  Group Entity for the right to distribute such New Programming.

                                    (e) The Intercable Group Entities shall
                  carry Investor Programming on the Systems until December 20,
                  2009 (or the expiration date of the applicable programming
                  agreement with the Company) in accordance with this Section
                  3.5.

                                    (f) For purposes of this Section 3.5 the
                  term "Disinterested Directors" shall mean any director who
                  would be considered a "disinterested director" for the
                  purposes of Section 7-108-501 of the Colorado Business
                  Corporation Act.

                                    (g) Notwithstanding anything to the contrary
                  contained in this Agreement, Investor may assign on behalf of
                  itself and the Bell International Group Entities its rights
                  under this Section 3.5 to Comcast."

         1.5. Upon the amendment to Section 3.5 of the Shareholders Agreement

account or accounts as Jones shall designate in consideration of the termination

Amendment, the provisions of the Shareholders Agreement shall remain in full

Comcast/Jones Agreement shall not constitute or be deemed to be a waiver by any
party of (a) any rights or claims that such party had or may have under the
Shareholders Agreement as amended hereby or (b), in the event that the
Comcast/Jones Agreement is terminated, any rights or claims that the Jones
Entities or the Company had or may have against the BTH Entities by reason of
the execution, delivery or performance of the Comcast/BTH Agreement.

                                OTHER AGREEMENTS

         2.1. Agreement to Stay Proceedings. In consideration of Comcast's

matter of the Litigation and the appeal of the order entered on May 5, 1998
until the first to occur of (i) the date on which both the Closing (as defined

         2.3. (a) Tax Matters. (a) The Company shall and International shall
cause Jones Education Company ("Education") and Entertainment to provide BTH
with certification and file notice(s) with the Internal Revenue Service within
10 days after the request of BTH regarding any disposition undertaken in
connection with the Comcast/BTH Agreement, which certification or notification,
as the case may be, shall attest to the fact that the BTH Entities' interest in
such corporations does not constitute a "real property interest" within the

access to the books and records and employees of the Company, Education and
Entertainment to enable the BTH Entities to confirm whether or not their
respective investments in such entities will constitute "excluded property"
within the meaning of the Income Tax Act (Canada) (i.e., that no more than 10%
of the assets of such entities consist of passive assets) as of the Simultaneous
Closing Date or the Initial Closing Date and the Final Closing Date, as the case
may be.

         2.4. Termination of Certain Agreements. The BTH Entities, the Jones
Entities and the Company agree and acknowledge, on their own behalf and on
behalf of their respective Affiliates, that the Secondment Agreement, the Fee
Sharing Agreement, the Financial Services Agreement and the Supply and Services

and conditioned upon the consummation of the Closing and the Simultaneous
Closing; provided that anything contained in Section 2.2 to the contrary
notwithstanding, any moneys accrued for the account of BTH prior to termination
of such agreements shall be paid to BTH at the Closing or as soon as is
reasonably practicable thereafter.

         2.5. Approval of this Agreement. Each of the parties to this Agreement
and Amendment represents and warrants to the other parties hereto that (i) if it

Company and (iii) the assumption by an Affiliate of a Jones Entity of the
Company's rights and obligations under that certain lease dated December 23,
