$286,424,250 of its total $400,000,000 commitment thereunder.

         Subject to compliance with the terms of the Transaction Documents, BTH
from time to time intends to review its investment in the Company on the basis
of various factors, including the Company's business, financial condition,
results of operations and prospects, general economic and industry conditions,
the securities markets in general and those for the Company's securities in
particular, as well as other developments and other investment opportunities.
Based upon such review, BTH will take such actions in the future as BTH may deem
appropriate in light of the circumstances existing from time to time in
compliance with the terms of the Transaction Documents to which it is a party.
Such actions may include the acquisition of additional Class A Shares or Common
Shares through open market purchases, privately negotiated transactions, tender
offer, exchange offer or otherwise. Alternatively, such actions may involve the
sale of all or a portion of the Class A Shares or Common Shares held by BTH from
time to time in the open market, in privately negotiated transactions, through a
registered public offering or otherwise.

Item 5.  Interest in Securities of the Issuer.
         The response set forth in Item 5 of the Schedule 13 D is hereby
supplemented as follows:

         (a) No changes.

         (b) No changes.

         (c) No transactions in Class A Shares or Common Shares have been
effected during the last 60 days by BCE, BTH, US Cable or BTH Intercable
(collectively, the "BTH Entities"), any other person controlling any BTH Entity
or to the best of BTH's knowledge, any of the persons named in Schedule A, B, C
or D hereto.

         (d) Not applicable.

         (e) Not applicable.

Item 6.  Contracts, Arrangements, Understandings or Relationships with Respect
         to Securities of the Issuer.
         The response set forth in Item 6 of the Schedule 13D is hereby
supplemented as follows:

         On August 12, 1998, BTH, Comcast, the Company and the Jones Entities
entered into the Transaction Documents which contemplate, subject to the
satisfaction or waiver of certain conditions precedent, (i) the immediate
exercise of the Control Option and the acquisition by Comcast of the Class A
Shares and the Common Shares currently beneficially owned by BTH, (ii) the
resignation of certain directors of the Company other than those certain
directors mutually selected by Jones and BTH and (iii) the assignment to Comcast
of BTH's rights under the Shareholders Agreement (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 Amendment
No. 3 to this Schedule 13-d filed on May 27, 1998 ("Amendment No. 3").

         During the period beginning August 12, 1998 and ending on the earlier
to occur of the termination or expiration of the Jones/Comcast Agreement and the
Closing, BTH's ability to exercise the Control Option will be suspended.

         The Closing is conditioned on the satisfaction or waiver of certain
conditions precedent, including expiration of all applicable waiting periods
under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended,
receipt of certain other governmental and franchise approvals, 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, receipt of all material third party consents and approvals, truth
and accuracy of certain standard representations and warranties, absence of
material adverse change during the period commencing March 31, 1998 to and
including the earlier to occur or the Closing, the Initial Purchase and December
31, 1998, and compliance by each party in all material respects of the covenants
required of it pursuant to the Transaction Documents.

         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 Agreements or with respect to any judgement previously obtained in any
court of competent jurisdiction. Moreover, the Jones Entities, the Company, BTH,
US Cable and BTH 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 Jones Intercable, Inc.,
Jones International, Ltd., Jones Internet Channel, Inc. and Glenn R. Jones,
which was filed before the U.S. District Court for the

                                       12
<PAGE>



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
Jones/Comcast Agreement.

         In the event the Closing occurs on or prior to June 30, 1999, Comcast
will pay BTH $500,000,000 in cash consideration at the time of the Closing;
otherwise consideration for the Initial Purchase and the Final Purchase will be
made as described in Amendment No. 3.

         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 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 Amendment No. 3.

certify that the information set forth in this Statement is true, complete and
correct.

         WHEREAS, the Company, Jones, International and BTH are parties to a

Agreement, Comcast and the BTH Entities have entered into an amendment to the
Original Comcast/BTH Agreement amending, among other things, the timing of the

         WHEREAS, Comcast and the Jones Entities desire to set forth their
agreement regarding certain matters relating to the transactions contemplated by
the amendments to the Option Agreements, the Comcast/BTH Agreement and the
Shareholders Agreement;

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

                  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").

                                      -2-
<PAGE>

                                    (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).

                           (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.

                                      -3-
<PAGE>

                           (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.

                           (b) All authorizations, consents, approvals or other
actions by, in respect of or filings with any Governmental Authority in the
United States, England or Spain, or any other country where any Intercable Group
Entity conducts material business required (including the obtaining of any
approvals from Franchise Authorities) to permit the consummation of the
transactions contemplated hereby shall have been taken or obtained, as the case
may be, and shall be in full force and effect; provided that if all
authorizations, consents and approvals from applicable Franchise Authorities
necessary to effect the change of control of the Franchises (i) relating to the
Franchises (whether in Owned Systems or Managed Systems) set forth on Schedule
F, (ii) relating to Franchises in Managed Systems which, as of the Closing Date,
are subject to a letter of intent or agreement of sale providing for the sale or
other disposition of such Managed System to a Person other than the Company (or
its wholly owned Subsidiaries), and (iii) relating to Franchises with not less
than 10,000 basic subscribers in Systems (whether Owned Systems or Managed
Systems) acquired by any Intercable Group Entity (except for Managed Systems
which, as of the Closing Date, are subject to a letter of intent or agreement of
sale providing for the sale or other disposition of such Managed System to the
Company or one of its wholly owned Subsidiaries) after the date hereof (the
"Required Franchise Approvals") shall have been so obtained, be in effect and
not be subject to withdrawal or appeal then the condition contained in this
paragraph (b) shall be deemed to be fulfilled as it relates to authorizations,
consents or approvals from applicable Franchise Authorities on the date on which
all of the Required Franchise Approvals are so obtained and are in effect and
not subject to withdrawal or appeal and provided further that this condition
shall not be satisfied if any Required Franchise Approval shall not have been
obtained.

                           (c) There shall not then be in effect any applicable
law, rule or regulation or any judgment, injunction, order or decree that has
one or more of the effects described in clauses (i), (ii) or (iii) of the
following paragraph (d); provided that if after the date hereof 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 such effects, then this paragraph (c) will not apply to any such
law, rule or regulation.

<PAGE>

                           (d) There shall not then be instituted or pending any
action or proceeding before any federal or state court or other Governmental
Authority brought by a Governmental Authority challenging the consummation of
the transactions contemplated hereby or seeking to (i) prevent Comcast from
consummating the transactions contemplated hereby, including exercising (or
directing BTH Intercable (or its Affiliates and agents) to exercise) the Control
Option or prevent BTH Intercable (or its Affiliates and agents) from exercising
the Control Option, (ii) require Comcast to divest, or otherwise limit Comcast's
ability to exercise full rights of ownership over the Control Option or the
Optioned Shares or any shares of capital stock of the Company owned by Comcast,
BTH, BTH Intercable or their respective Affiliates, or (iii) require, after the
exercise of the Control Option, Comcast or the Intercable Group to divest any
material business or assets or which would impose a material limitation on the

transactions contemplated thereby; and (B) the BTH Entities having provided to
Comcast any information received by them or the Investor Nominees. In the event

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

                  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

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.

contemplated hereby confidential until mutual agreement is reached in writing
regarding publicity or until otherwise required by law (and as to the latter the
parties will make reasonable efforts to consult with each other).

                  15. Standstill. From the date of the execution of this
Agreement until the Closing or termination of this Agreement, the Jones
Entities, on behalf of themselves and each of their Affiliates, agents,
officers, consultants, and representatives, agree not to solicit, encourage or
negotiate with any other 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 written notice to the other parties hereto of such termination if (x) the

herein and the Jones Entities have failed to cure such breach within fifteen
(15) calendar days of receipt of written notice of such breach from Comcast, (y)
all of the conditions to closing set forth in Sections 3 and 4 hereof shall have

condition which has not been fulfilled or waived because of the Jones Entities'
breach of 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
to closing set forth in Sections 3 and 4 hereof shall have been fulfilled or

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

                            FORM OF 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").


<PAGE>

          (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.

          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

<PAGE>

(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.

          7. Notices. All notices, requests, claims, demands and other
communications hereunder shall be deemed to have been duly given when delivered
in person, by facsimile transmission, nationally-recognized overnight courier
service or by registered or certified mail (postage prepaid, return receipt
requested):

                              FORM OF 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.


                                       1
<PAGE>





         (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

                                       2
<PAGE>




         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.


                                       4

         (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

                                       5
<PAGE>




         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").

         (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.

                                       6
<PAGE>




         (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.

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 KTV. Further,
         Affiliate acknowledges and agrees that all names, logos, marks,
         copyright notices or designations utilized by KTV in connection with
         the Service (the "Marks") are the sole and exclusive property of KTV
         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 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.

9.       REPRESENTATIONS AND INDEMNIFICATION

         (a) KTV represents and warrants to Affiliate that (i) it is a
         corporation duly organized and validly existing and in good standing
         under the laws of the State of Colorado; (ii) KTV has the corporate
         power and authority to enter into this Agreement and to fully perform
         its obligations hereunder; (iii) KTV is under no contractual or other
         legal obligation which in any way interferes with its ability to fully,
         promptly and completely perform hereunder; (iv) the individual
         executing this Agreement on behalf of KTV has the authority to do so;
         (v) KTV is operating in substantial compliance with all applicable
         laws, rules and regulations; (vi) nothing contained in the Service
         shall violate the civil or property rights, copyrights, trademark
         rights, right of privacy or any other right of any person, firm or
         corporation except that no representation and warranty is given with
         respect to music performance rights, subject to the indemnification
         obligation of KTV pursuant to Section 9(d) hereof; and (vii) the
         license fee rates set forth on Exhibit B attached hereto for the years
         2002, 2003 and 2004 are the standard license fee rates for KTV, and
         have been agreed to in at least one written 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 KTV that (i) Affiliate is a
         corporation duly organized and validly existing and in good standing
         under the laws of the

                                       8
<PAGE>




         Commonwealth of Pennsylvania; (ii) Affiliate has the corporate power
         and authority to enter into this Agreement and to fully perform its
         obligations hereunder; (iii) the individual executing this Agreement on
         behalf of Affiliate has the authority to do so; and (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
         liabilities, claims, costs, damages and expenses (including, without
         limitation, reasonable counsel fees) arising out of any breach or
         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

                                       9
<PAGE>




         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.


                                       10

         (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.


                                       11
<PAGE>




         (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) 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

                                       12
<PAGE>




         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.

IN WITNESS WHEREOF, the parties hereto have entered into this Agreement as of
the date first set forth above.

                         FORM OF GREAT AMERICAN COUNTRY
                               AFFILIATE AGREEMENT


                  THIS AGREEMENT is made as of the ___ day of ______________,
199_, by and between GREAT AMERICAN COUNTRY, INC., a Colorado corporation 
("G A C"), 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, G A C hereby
         grants to Affiliate the non-exclusive license to distribute the "Great
         American Country" 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 G A C 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 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


                                       1
<PAGE>




         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.

         (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

                                       2
<PAGE>




         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;

                                       3
<PAGE>




         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.

         (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

                                       4
<PAGE>




         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.

         (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.


                                       5
<PAGE>




         (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

                                       6
<PAGE>




         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,
         telegraph, personal delivery, certified mail, return receipt requested,

8.       TRADEMARKS

                                       7
<PAGE>




         (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.

         Communications, Inc.", "Comcast Cablevision" and the concentric "C"
         mark are the exclusive property of Affiliate and/or its affiliated
         entities, and that G A C has not and will not acquire any 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.

9.       REPRESENTATIONS AND INDEMNIFICATION

         (a) G A C represents and warrants to Affiliate that (i) it is a
         corporation duly organized and validly existing and in good standing
         under the laws of the State of Colorado; (ii) G A C has the corporate
         power and authority to enter into this Agreement and to fully perform
         its obligations hereunder; (iii) G A C is under no contractual or
         other legal obligation which in any way interferes with its ability to
         fully, promptly and completely perform hereunder; (iv) the individual
         executing this Agreement on behalf of G A C has the authority to do
         so; (v) G A C is operating in substantial compliance with all
         applicable laws, rules and regulations; (vi) nothing contained in the
         Service shall violate the civil or property rights, copyrights,
         trademark rights, right of privacy or any other right of any person,
         firm or corporation except that no representation and warranty is given
         with respect to music performance rights, subject to the
         indemnification obligation of G A C pursuant to Section 9(d) 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 for 
         G A C, and have been agreed to in at least one written affiliate
         agreement with a

                                       8
<PAGE>




         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 is
         a corporation duly organized and validly existing and in good standing
         under the laws of the Commonwealth of Pennsylvania; (ii) Affiliate has
         the corporate power and authority to enter into this Agreement and to
         fully perform its obligations hereunder; (iii) the individual executing
         this Agreement on behalf of Affiliate has the authority to do so; and
         (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 G A C 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
         liabilities, claims, costs, damages and expenses (including, without
         limitation, reasonable counsel fees) arising out of any breach or
         claimed breach by it of any representation or warranty or any of its
         obligations pursuant to this Agreement. G A C will credit Affiliate
         for any continuous interruption of Service caused by G A C 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. G A C'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, G A C 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 G A C, Affiliate and/or the Systems
         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 performance
         rights related to the exhibition and distribution of the Service by 
         G A C, 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

                                       9
<PAGE>




         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

                                       10
<PAGE>




         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

                                       11
<PAGE>




         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.

         (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.


                                       12

         (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.

         THEREFORE, in consideration of the mutual covenants contained herein

                                    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) 

                                      -2-
<PAGE>


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 Date") and (ii) on the first date following the day on which
all of the conditions precedent contained in Sections 8.5 and 8.6 are satisfied
or waived (the "Final Closing Date"), the Remaining Subsidiary Stock (or such
alternative shares as contemplated by Section 8.4(c)) (the "Final Purchase").
Comcast currently intends to explore the possibility of a consensual transaction
with Jones and/or the Company and BTH during the aforementioned 90-day period
pursuant to which BTH would receive $500,000,000 in exchange for its interests
in the Company and the Affiliate Stock and Comcast has entered into the
Jones/Comcast Agreement to effect such a consensual transaction with Jones.

                    (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 "Simultaneous Closing") and on the same date as the closing (the
"Jones/Comcast 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 within 5 Business Days of the earlier of such
occurrence. If the Jones/Comcast Closing shall not have occurred on the date the
Simultaneous Closing occurs, then the transactions to be effected at the
Simultaneous Closing and the Jones/Comcast Closing shall be rescinded and deemed
not to have occurred. In connection with the Simultaneous Closing, unless
Comcast shall have notified BTH in writing to the contrary at least two days
prior to the Simultaneous Closing Date, Comcast shall be deemed to have made the
election described in Section 8.4(c) not to receive the 49% Subsidiary Stock or
the Remaining Subsidiary Stock but to receive instead all of the shares of
capital stock of the Company (including the Control Shares) owned beneficially
or of record by US Cable, Intercable or any of their Affiliates as of the
Simultaneous Closing Date. The Simultaneous Closing Date shall be deemed to be
the Initial Closing Date and the Final Closing Date for purposes of Articles III
through XII hereof and the Simultaneous Closing shall be deemed to be the
Initial Closing and the Final Closing for purposes of Articles III through XII
hereof.

Section 1.2. Purchase Price. (a) Comcast agrees to pay BTH an amount equal to
$500,000,000 (the "Purchase Price"), 80% of which shall be payable on the
Initial Closing Date (the "Initial Closing Payment") and 20% of which shall be
payable on the Final Closing Date (the "Final Closing Payment"). In connection
with a Simultaneous Closing, 100% of the Purchase Price, constituting both the
Initial Closing Payment and the Final Closing Payment, shall be payable on the
Simultaneous Closing Date. If a Simultaneous Closing occurs after December 31,

                                      -3-
<PAGE>


1998, Comcast agrees to also pay BTH interest on the Purchase Price at the
Applicable Rate from December 31, 1998 to the Simultaneous Closing Date.

                    (b) Amounts payable pursuant to this Section 1.2 and
Sections 7.3(e), 8.2(b) and 8.8 shall be made by Comcast in immediately
available funds to one or more accounts designated by BTH at least two days
prior to the date any such payment is due.

                    (c) The foregoing purchase and sale and the Purchase Price
payable with respect thereto, shall be subject to adjustment as provided in
Sections 7.3(e), 8.2(b) and 8.8 of this Agreement.

                                   ARTICLE II
                                 EFFECTIVE TIME


Section 2.1. Effective Time. This Agreement will become effective immediately.

                                   ARTICLE III
                      REPRESENTATIONS AND WARRANTIES OF BTH

                  BTH hereby represents and warrants to Comcast that:

Section 3.1. Organization and Standing.

                    (a) BTH is a corporation duly organized, validly existing
and in good standing under the laws of Canada with full corporate power and
authority to own, lease, use and operate its properties (including, without
limitation, the shares of capital stock of its subsidiaries) and to conduct its
business as and where now owned, leased, used, operated and conducted. BTH 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 could
not reasonably be expected to prevent, materially interfere with or materially
delay the consummation of the transactions contemplated hereby. BTH is not in
default in the performance, observance or fulfillment of any provision of its
articles of incorporation or bylaws (or similar organizational documents) which
could reasonably be expected to prevent, materially interfere with or materially
delay the consummation of the transactions contemplated hereby.

                    (b) Each of the BTH Subsidiaries is a corporation duly
organized, validly existing and in good standing under the laws of the British
Virgin Islands with full corporate power and authority to own, lease, use and
operate its properties (including, without limitation, in the case of US Cable,
to own the Class A Shares and the Affiliate Stock and, in the case of
Intercable, to exercise the Control Option and to purchase and hold the Control
Shares) and to conduct its business as and where now owned, leased, used,
operated and conducted. Each of the BTH Subsidiaries is duly qualified to do
business and in good standing in each jurisdiction in 

                                      -4-
<PAGE>


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 could not reasonably be expected to have a Material Adverse Effect on
either of the BTH Subsidiaries or prevent, materially interfere with or
materially delay the consummation of the transactions contemplated hereby. The
BTH Subsidiaries are not in default in the performance, observance or
fulfillment of any provision of their memorandum of association and articles of
association which could reasonably be expected to have a Material Adverse Effect
on the BTH Subsidiaries or prevent, materially interfere with or materially
delay the consummation of the transactions contemplated hereby.

                    (c) True, complete and correct copies of the memorandum of
association and articles of association for each of the BTH Subsidiaries have
been delivered to Comcast and such memorandum of association and articles of
association have not been amended, modified or rescinded since the date of such
delivery to Comcast and are in full force and effect.

Section 3.2. Ownership of the Class A Shares. US Cable owns beneficially and of
record the Class A Shares, free and clear of any Claims.

Section 3.3. Capitalization.

                    (a) US Cable has authorized share capital of $500,000,000
which is divided into 500,000,000 shares each having a par value of US $1.00 of

                    (e) In the event that BTH, the BTH Subsidiaries or their

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

                                       -18-
<PAGE>


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

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

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.

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

Section 8.8. Alternative Final Closing Procedures.

                    If an event or circumstance has occurred such that
satisfaction of a 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
assign its rights under the Control Option Agreements pursuant to Section
10.2(a)(iii), then BTH shall pay to Comcast an amount equal to $150,000,000 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 Section 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 BTH shall
deliver to Comcast all of the Remaining Subsidiary Stock (and Comcast shall have
the right to make the same election with respect to the Remaining Subsidiary
Stock as described in Section 8.4(c)) and Comcast shall have no obligation to
pay to BTH the Final Closing Payment.

                    (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)

                                      -30-
<PAGE>


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 acquired by Comcast at the Initial Closing together with any
dividends or distributions upon or with respect to such stock and Comcast shall
have no obligation to pay to BTH the Final Closing Payment.

                    (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.

<PAGE>

                    (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.

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

<PAGE>

damages for breaches of representation or warranty. BTH shall be required to
take all reasonable steps to mitigate its Losses.

                    (d) Notwithstanding anything to the contrary contained in

compensated for its Losses from an insurance company or any other third party,
Comcast's indemnification obligation in respect of any such Losses shall be
reduced by an equal amount.

                    (e) The obligation of Comcast to indemnify the BTH
Indemnified Parties for matters contemplated by Section 8.8 shall be limited to
the exclusive remedies set forth therein.

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

                                      -36-
<PAGE>
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

<PAGE>

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.

         "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 and (y) one-third of 120% of the Market Value of a share of Class
         A Common Stock on the applicable Trigger Date(1) 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

- ------------------
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).


                                      -7-

         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).

         (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:


- ---------
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).

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.

                                      -9-

except as otherwise agreed to between Grantor, its Affiliates, and BTH in the
Shareholders Agreement or otherwise, or between Grantor, its Affiliates and

Agreement is hereby amended by adding the following to the end of such section:

         "Notwithstanding the foregoing, the parties hereto agree that this
         Section 3.10 shall not prohibit any of the parties from disclosing all
         such documents and information received after August 12, 1998 and until
         the earlier to occur of (x) the Closing of the transactions
         contemplated by that certain Agreement, dated August 12, 1998, by and
         among Comcast Corporation, a Pennsylvania corporation ("Comcast") Jones
         International and certain JI Group Entities named therein (the
         "Comcast/Jones Agreement") or (y) the expiration or termination of the
         Comcast/Jones Agreement from the other parties to this Agreement (and
         Affiliates of such other parties), including any information provided
         by the Company to any Investor Nominee, to Comcast, and to the
         officers, directors, employees, agents, representatives and advisors
         (including, without limitation, legal and financial advisors) of
         Comcast.

         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

                                      -4-
<PAGE>


                  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
contained in Section 1.4 hereof becoming effective the Company shall pay to
Jones and International $25,000,000 in immediately available funds to such bank
account or accounts as Jones shall designate in consideration of the termination
of the JI Group Entities' rights under Section 3.5 of this Agreement.

Amendment, the provisions of the Shareholders Agreement shall remain in full
force and effect. Except as set forth in Section 2.2, below, execution and
delivery of this Agreement and Amendment, the Option Agreements and the
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.

         2.2. General Release. In consideration of Comcast's execution and
delivery of the Comcast/Jones Agreement and the Comcast/BTH Agreement each of
(i) the Jones Entities and the Company and (ii) each of the BTH Entities, in the
case of each of (i) and (ii), on behalf of itself and each of its Affiliates
(including the Company and its subsidiaries) (the "Releasing Parties"),
effective as of and conditioned upon the consummation of both the Closing (as

hereafter can, shall or may have against any of the BTH Entities and the Jones

                                      -6-
<PAGE>

(as defined in the Comcast/Jones Agreement) and the Simultaneous Closing Date
(as defined in the Comcast/BTH Agreement) shall both have occurred.
Notwithstanding the foregoing nothing in this Section 2.2 shall release any

such corporations does not constitute a "real property interest" within the
meaning of the Internal Revenue Code and shall otherwise conform with the
requirements of United States Treasury Regulation 1.897-2(h).

                               (b) Promptly upon request the Company shall, and

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.
