         2.  THE ABCN SYSTEM.  HTS acknowledges that ABCN desires to 
implement a fully integrated DBS System based in part on certain technology 
utilized by the EchoStar System to offer direct broadcast satellite 
television services throughout the Territory.  Implementing the ABCN System 
will involve (a) Systems Development, (b) the use, in connection with such 
Systems Development, of the Software, which has been developed or obtained by 
HTS or other EchoStar Affiliates for use in the EchoStar System, and (c) the 
manufacture and distribution to consumers of Licensed Receiver Products (as 
modified for the Territory in accordance with the terms herein) which will 
enable such consumers to have access to the signals transmitted using the 
systems developed pursuant to the Systems Integration Agreement.  

         3.  ACCESS RIGHTS.

              3.1.  ACKNOWLEDGMENT.  HTS acknowledges the complexity of the 
ABCN System and that in order for ABCN to operate a DBS System (and realize 
value from the Software and Licensed Receiver Products), ABCN needs to 
develop a thorough understanding and working knowledge thereof, including in 
particular principles and procedures for operation and maintenance of a 
digital broadcast center, which the parties agree shall be obtained through 
the implementation of the activities contemplated in Section 3.2 below.  

              3.2.  DISCLOSURE.  From and after the execution of this 
Agreement, HTS agrees to disclose to ABCN, and to afford ABCN full, complete 
and open access (in a manner reasonably designed by HTS to minimize 
disruption to its business and maintain the integrity of its files or other 
information retention system) to, all information (whether existing or 
subsequently created or obtained) reasonably requested by ABCN which 
embodies, supplements or is otherwise necessary or helpful in understanding 
the EchoStar System, the Non-HTS Systems Development Technology (subject to 
any written and binding confidentiality limitations to which HTS or other 
EchoStar Affiliates may be subject), the Software and Licensed Receiver 
Products and the Non-HTS Receiver Technology (subject to any written and 
binding confidentiality limitations to which HTS or other EchoStar Affiliates 
may be subject); provided, however, that HTS shall not  be required under 
this Agreement to provide ABCN with any proprietary technology or other 
information except such proprietary technology and information which is 
relevant to the ABCN System, based upon the BSS, Ku-band direct broadcasting 
satellites included in ABCN's L-Star satellite system. Such access shall 
include on-site visits to the digital broadcast center operated by EchoStar 
Affiliates in Cheyenne, Wyoming (the "Cheyenne Broadcast Facility") and other 
locations where the EchoStar System is deployed (subject to reasonable 
restrictions of HTS or other EchoStar Affiliates to physical areas which are 
"high security"), access by ABCN personnel, consultants, and other 
representatives to relevant documents describing the EchoStar System, the 
Non-HTS Systems Development Technology, the Software and Licensed Receiver 
Products and the Non-HTS Receiver Technology, and reasonable opportunities to 
confer with HTS technical personnel who are knowledgeable in and experienced 
with the same, at reasonable times and in such manner as is reasonably 
specified by HTS to minimize disruption to its business.  HTS shall determine 
which information or documents are to be disclosed pursuant to this Section, 
using its reasonable judgment, acting in good faith.  In the event that HTS 
determines that certain documents or information to which ABCN requests 
access are not relevant and are not to be disclosed pursuant to this Section, 
HTS shall provide to ABCN a written description of the reasons for 
non-disclosure. 

              3.3.  USE OF INFORMATION.  Subject to Sections 13.3, 13.4 and 
14 below, HTS hereby grants to ABCN, and ABCN hereby accepts, a limited, 
perpetual, non-transferable, non-exclusive, royalty-free right and license 
(or sub-license in the case of information of which HTS is the licensee of 
licensors other than EchoStar Affiliates) to copy, use and deal with the 
information described in Section 3.2 (except in the case of documents and 
information included in the Non-HTS Systems Development Technology and 
Non-HTS Receiver Technology, to the extent that HTS and other EchoStar 
Affiliates are prohibited from granting such rights) solely for the purposes 
of the construction, operation and maintenance of the ABCN System.  
Disclosure to ABCN of confidential 

                                     -3-
<PAGE>

information under this Section may be made subject to ABCN entering into 
reasonable confidentiality agreements required by third parties with rights 
in portions of the Non-HTS Receiver Technology and Non-HTS Systems 
Development Technology.  

         4.  PROPRIETARY SOFTWARE LICENSE.

              4.1.  ECHOSTAR SOFTWARE LICENSE.  Subject to Section 4.2 
hereof, HTS hereby grants to ABCN, and ABCN hereby accepts, a limited, 
non-transferable, non-exclusive, royalty-free right and license to install, 
operate, utilize and administer the EchoStar Software, in the form of machine 
readable object code, except as provided below (and a substantially similar 
sub-license, in the case of the Third Party Software which HTS is permitted 
to sub-license, if any), solely for use in providing DBS service in the 
Territory as part of the ABCN System (the "Software License").  Such right 
and license shall be for a term from the date hereof through the end of the 
useful lives of the satellites comprising ABCN's L-Star satellite system.

              4.2.  LIMITATIONS ON RIGHTS.  The EchoStar Software (including 
any derivative works or modifications thereof) shall at all times remain the 
exclusive property of HTS, or its licensors, as the case may be, and except 
as provided below, ABCN shall not disclose the Software to any third party 
(other than with respect to the EchoStar Receiver Software to an Acceptable 
Asian Manufacturer with a Receiver License (as defined below) from HTS or 
other EchoStar Affiliate) for any purpose whatsoever, or grant or attempt to 
grant sub-licenses in respect of the EchoStar Software, without HTS's prior 
written consent, which consent may be withheld by HTS in its absolute 
discretion. Except as provided below, ABCN shall not copy the EchoStar 
Software (other than back-up copies for ABCN's own use), disassemble, 
decompile or reverse engineer any of the EchoStar Software, or incorporate 
any of the EchoStar Software into any other software or products (except to 
the extent permitted under this Agreement or the Receiver Licenses 
contemplated hereby) without HTS's prior written consent, which consent may 
be withheld by HTS in its absolute discretion.

              4.3.  NO WARRANTY.  ABCN acknowledges and agrees that the 
EchoStar Software licensed to ABCN hereunder is licensed on an "as-is" basis, 
and that HTS makes no warranty whatsoever as to the usefulness of the 
EchoStar Software for any particular purpose.

         5.  RIGHT TO PURCHASE LICENSED RECEIVER PRODUCTS.

              5.1.  RIGHT TO PURCHASE.  ABCN shall have the right, from time 
to time, to purchase Licensed Receiver Products in such quantities as ABCN 
may specify and which the EchoStar Affiliates can, in their reasonable 
judgment, deliver to ABCN.  The price of such purchase shall be no less 
favorable than the price of the same goods to other customers of HTS and 
other EchoStar Affiliates under like terms and conditions (taken as a whole) 
and shall include commercially reasonable terms of delivery to ABCN's 
premises or other locations. HTS shall provide to ABCN, from time to time 
upon reasonable request, a list of the prices and terms for purchase of 
Licensed Receiver Products complying with the foregoing provisions of this 
Section.  

              5.2.  PURCHASE ORDERS.  Any orders by ABCN for Licensed 
Receiver Products manufactured by or on behalf of HTS or any other EchoStar 
Affiliates must be evidenced by a written purchase order (a "Purchase 
Order").  Each Purchase Order shall be subject to confirmation and acceptance 
by HTS or the relevant EchoStar Affiliate, and shall be a binding commitment 
by ABCN upon written notice of acceptance by HTS to ABCN in accordance with 
the terms of the Purchase Order.  Any failure to confirm a Purchase Order 
shall not be deemed acceptance by HTS.  HTS (or the relevant EchoStar 
Affiliate) will use reasonable commercial efforts to fulfill all Purchase 
Orders issued by ABCN which meet the requirements of this Section 5.  
Purchase Orders shall state only:  (i) identity of goods; (ii) quantity of 
goods; (iii) purchase price of goods; (iv) requested ship date of goods and 
(v) the date by which the Purchase Order must be accepted but in no event 
less than 5 business days from receipt of the P.O. by HTS.  Any additional 
terms stated in a Purchase Order shall not be binding upon HTS unless 
expressly agreed to in writing by HTS.  In the event of any conflict between 
the terms of a Purchase Order and the terms of this Agreement, the terms of 
this Agreement shall prevail.  

                                        -4-
<PAGE>

              5.3.  PURCHASE OF MODIFIED PRODUCTS.  To the extent that ABCN 
wishes to order any Licensed Receiver Products from HTS which differ in any 
material respect from the same product manufactured by or on behalf of any 
EchoStar Affiliate for use in connection with the Dish Network operated by 
the EchoStar Affiliates in the United States, HTS shall have no obligation to 
provide such Licensed Receiver Products to ABCN unless the parties reach a 
mutually satisfactory agreement in writing on any (i) modifications or 
enhancements to the Licensed Receiver Products pursuant to this Agreement; 
(ii) applicable volume commitments of ABCN, (iii) responsibility for any 
non-recurring expenses associated with production; and (iv) other reasonable 
commercial terms.

              5.4.  MANUFACTURE FOR ABCN SYSTEM.  ABCN hereby authorizes and 
licenses HTS or any other EchoStar Affiliate HTS designates to manufacture 
and sell Licensed Receiver Products to distributors, dealers and consumers in 
the Territory.  HTS and other EchoStar Affiliates shall be entitled to 
utilize, for the purposes of such manufacturing, either its own facilities or 
the facilities of any third party manufacturer which, at the time HTS or 
other EchoStar Affiliate manufactures any Licensed Receiver Product, also 
manufactures in the United States or elsewhere Licensed Receiver Products for 
HTS and or other EchoStar Affiliates for use in connection with the Dish 
Network in the United States.   Notwithstanding the foregoing authorization, 
HTS and other EchoStar Affiliates shall be under no obligation to manufacture 
any Licensed Receiver Products for sale in the Territory unless it chooses to 
do so in its sole discretion.  In the event HTS or any other EchoStar 
Affiliate does manufacture Licensed Receiver Products for sale in the 
Territory, ABCN shall provide to HTS or other EchoStar Affiliate marketing 
assistance, designed to enhance the sales prospects for such products, of the 
same type and on terms (taken as a whole) which are no less favorable than 
any such marketing assistance provided by ABCN to the Acceptable Asian 
Manufacturers with Receiver Licenses.  For purposes of this Section 5.4, the 
term "marketing assistance" shall include without limitation any economic 
subsidization of the manufacturing costs of the Licensed Receiver Product for 
sale in the Territory.  

         6.  LICENSE TO THIRD PARTY MANUFACTURERS.

              6.1.  LICENSE FOR LICENSED RECEIVER PRODUCTS.  HTS or the 
relevant EchoStar Affiliate shall grant, to two Acceptable Asian 
Manufacturers (as defined below) selected by ABCN as provided in Section 6.3, 
a limited, non-exclusive right and license to manufacture, sell and 
distribute any or all of the Licensed Receiver Products intended solely for 
use within the Territory, each of which licenses shall be governed by and 
subject to a License Agreement described in Section 6.2 (each, a "Receiver 
License").  Each Receiver License shall be for a term of not less than 
[CONFIDENTIAL MATERIAL REDACTED] following execution of the License Agreement 
for such Receiver License, and shall provide for options for the Acceptable 
Asian Manufacturer to extend the Receiver License (i) for an additional 
[CONFIDENTIAL MATERIAL REDACTED] term and (ii) from the end of such 
additional term through the end of the useful lives of the satellites 
comprising ABCN's L-Star satellite system, in each case subject to the right 
of HTS or the relevant EchoStar Affiliate to refuse to extend the Receiver 
License in good faith, for good commercial reasons.  To the extent that the 
Licensed Receiver Products contain Third Party Software or Non-HTS Receiver 
Technology that none of the EchoStar Affiliates have the right to sub-license 
to ABCN, HTS will use reasonable commercial efforts to assist ABCN in 
obtaining a license or agreement to license that will entitle the two 
Acceptable Asian Manufacturers to manufacture, sell and distribute any or all 
of the Licensed Receiver Products including such Third Party Software or 
Non-HTS Receiver Technology within the Territory.  

              6.2.  LICENSE AGREEMENT.  Each Receiver License shall be on 
substantially the terms and conditions set forth in the License Agreement 
attached as EXHIBIT A hereto, the terms of which shall provide for a royalty 
of [CONFIDENTIAL MATERIAL REDACTED] of Licensed Receiver Products packaged 
for sale or delivery to a single consumer in the Territory where ABCN 
provides DBS services.  In the event that HTS or any other EchoStar 
Affiliate:  (i) grants a license to another manufacturer (other than pursuant 
to this Agreement) to manufacture, sell and distribute MPEG II DVB compliant 
integrated digital DBS receiver decoders ("DBS IRDs") within the Territory; 
and (ii) receives a [CONFIDENTIAL MATERIAL REDACTED] royalty from any such 
manufacturer of less than [CONFIDENTIAL MATERIAL REDACTED] (the "Lower 
Royalty") for the manufacture, sale and distribution of DBS IRD's intended 
solely for use within the Territory, then each Acceptable Asian 
Manufacturer's [CONFIDENTIAL MATERIAL REDACTED] royalty of 
[CONFIDENTIAL MATERIAL REDACTED] shall be reduced to the same amount as the 
Lower Royalty; provided, however, that if the Lower Royalty only becomes due 
to HTS or other EchoStar Affiliate from the third 

                                        -5-
<PAGE>

party manufacturer after the manufacture and sale of a certain number of 
units [CONFIDENTIAL MATERIAL REDACTED], the Acceptable Asian Manufacturers 
shall not be entitled to the Lower Royalty unless and until the Lower Royalty 
becomes payable to HTS or other EchoStar Affiliate.  The two Receiver 
Licenses collectively may include an aggregate up-front fee of 
[CONFIDENTIAL MATERIAL REDACTED].  HTS shall use reasonable commercial 
efforts to enter into the Receiver Licenses with the two Acceptable Asian 
Manufacturers as soon as practicable after such companies have been selected 
by ABCN as provided in Section 6.4.  

              6.3.  TERMINATION RIGHT.  If HTS does not enter into any 
Receiver License, despite its efforts under Section 6.1 and 6.2, within 180 
days after the first Acceptable Asian Manufacturer is selected by ABCN, and 
ABCN determines in its reasonable judgment acting in good faith that such 
failure prevents ABCN from realizing any significant benefit from this 
Agreement, ABCN shall have the right, by written notice to HTS, to terminate 
this Agreement and the Rights Options.  In the event of such termination, 
each party shall have the right (unilaterally), by written notice to the 
other party, to terminate the Systems Integration Agreement and the Systems 
Development Option.  HTS shall be entitled to retain amounts paid under any 
agreements so terminated to the extent that such payments are for services 
performed or costs incurred by HTS, and shall be entitled to receive any 
further amounts which it has earned, and shall refund any other amounts 
received thereunder.  ABCN shall be entitled to retain any benefits from 
services received prior to such termination, and shall return any property of 
HTS in ABCN's possession, and continue to abide by all confidentiality  
provisions in the terminated agreements.  These obligations under this 
section shall survive termination of this Agreement. 

              6.4.  ACCEPTABLE ASIAN MANUFACTURER.  "Acceptable Asian 
Manufacturer" shall include (i) the companies described on SCHEDULE 4 to this 
Agreement, and (ii) any other manufacturer located in the Territory that is 
competent and capable of manufacturing consumer electronic products to world 
market specifications as demonstrated, INTER ALIA, by the presence of such 
manufacturer in world or regional markets for consumer electronic products; 
provided that any Acceptable Asian Manufacturer under (i) or (ii) above is 
approved by HTS in accordance with the remaining provisions of this Section 
6.4, which approval shall not be unreasonably withheld or delayed.  To select 
Acceptable Asian Manufacturers under this Agreement, ABCN shall notify HTS in 
writing of an initial designation of one or more Acceptable Asian 
Manufacturers pursuant to this Section.  HTS shall have a reasonable 
opportunity (not to exceed 60 days), with the assistance of ABCN (if 
requested by HTS), to investigate the operations and capabilities of each 
such Acceptable Asian Manufacturer.  HTS may, at any time during such 
investigation period, reject the designation of such entity, provided that 
such rejection is made in good faith for good commercial reasons.  If any 
such Acceptable Asian Manufacturer is not rejected by HTS and does not have 
its designation withdrawn by ABCN during such investigation period, such 
Acceptable Asian Manufacturer shall be deemed to have been "selected" by ABCN 
for purposes of this Agreement.

              6.5.  SUB-LICENSE FOR ASSEMBLY PURPOSES.  Subject to the terms 
and conditions of the Receiver Licenses, the Acceptable Asian Manufacturers 
with Receiver Licenses shall have the right to sub-license to third parties 
the rights to assemble the Licensed Receiver Products for sale or 
distribution in the Territory by ABCN or such Acceptable Asian Manufacturers. 
 

              6.6.  UNRESTRICTED RIGHTS.  Notwithstanding anything to the 
contrary contained herein, it is understood and agreed that HTS shall not be 
restricted from and shall retain unlimited rights to, among other things, 
manufacture, assemble, distribute, lease and sell the Licensed Receiver 
Products within the Territory during the term of this Agreement.  Such 
retained rights shall include without limitation the rights to distribute, 
lease and sell the Licensed Receiver Products to ABCN, Acceptable Asian 
Manufacturers, distributors, dealers and subscribers to ABCN's System, but 
ABCN, Acceptable Asian Manufacturers and subscribers to ABCN's System shall 
have no obligation to purchase, lease or otherwise obtain Licensed Receiver 
Products from HTS except as otherwise agreed.

<PAGE>

                   (a)  ABCN (directly or through an Acceptable Asian
Manufacturer with a Receiver License) shall be entitled to request HTS to
perform, or cause the applicable EchoStar Affiliate to perform, modifications or
enhancements (each a "Request") to the EchoStar Software resident in the
Licensed Receiver Products (the "EchoStar Receiver Software") which (i) are
necessary or desirable (in ABCN's reasonable determination) for the utilization,
sale or marketing of the Licensed Receiver Products by or to consumers in the
Territory in conjunction with the ABCN System, and (ii) require knowledge of and
access to the source code (the "Source Code") for the EchoStar Receiver Software
in order to perform the modification or enhancement which is the subject of the
Request.  Upon receipt of each Request, HTS (or other applicable EchoStar
Affiliate) and ABCN (or the Acceptable Asian Manufacturer, as the case may be)
shall in good faith discuss and agree in writing upon an acceptable delivery
date (the "Delivery Date") for the modification or enhancement which is the
subject of the Request.  ABCN (or the Acceptable Asian Manufacturer) shall be
responsible, to the extent possible given its lack of knowledge of the Source
Code, for development of the technical specifications for the modification or
enhancement requested.  HTS (or other applicable EchoStar Affiliate) shall use
commercially reasonable efforts to effect such modifications and enhancements by
the agreed Delivery Dates.  All changes to a Request that may be requested by
ABCN (or the Acceptable Asian Manufacturer) (i) must be submitted in writing to
HTS (or other applicable EchoStar Affiliate) in the form of a change order and
(ii) will extend the original Delivery Date by an amount of time HTS (or other
applicable EchoStar Affiliate) and ABCN (or the Acceptable Asian Manufacturer,
as the case may be) in good faith discuss and agree in writing (or, if they do
not so agree, as reasonably determined by HTS (or other applicable EchoStar
Affiliate) and confirmed to ABCN (or the Acceptable Asian Manufacturer, as the
case may be) in writing (a "Revised Delivery Date").

                   (b)  Notwithstanding any payment to HTS (or other applicable
EchoStar Affiliate) for the services contemplated in this Section 7.1, any and
all intellectual property rights which result from the development of the
modifications or enhancements hereunder shall remain the sole and exclusive
property of HTS (or other applicable EchoStar Affiliate); provided, however,
that "EchoStar Software" and "Licensed Receiver Products" shall include such
software and products as modified or enhanced hereunder and each Acceptable
Asian Manufacturer with a Receiver License shall receive a royalty free license
to use such modifications and enhancements for the sole purpose of manufacturing
and selling Licensed Receiver Products for use with the ABCN System in the
Territory during the term of such Acceptable Asian Manufacturer's Receiver
License.

                   (c)  For the services rendered by HTS or its Affiliates
pursuant to Section 7.1 above, ABCN (or the Acceptable Asian Manufacturers)
shall (i) pay HTS the hourly rates for its personnel set forth on SCHEDULE 5 (as
such Schedule may be amended with the written approval of both parties to
specify rates for new personnel), which rates shall be increased on January 1,
1998 and each anniversary thereof by the increase in the Consumer Price Index
during the preceding year and (ii) to reimburse HTS for its out of pocket costs
(subject to the prior approval requirements set forth in SCHEDULE 5 hereto)
which are reasonably incurred by HTS in connection with providing services
hereunder.  All such payments and reimbursements shall be made without any
withholding by ABCN for non-U.S. taxes, as provided in Section 17.7.

              7.2.  MODIFICATIONS AND ENHANCEMENTS OF THE ECHOSTAR RECEIVER
SOFTWARE BY ABCN OR AN ACCEPTABLE ASIAN MANUFACTURER.

                   (a)  Nothing in this Agreement shall prohibit ABCN, or an
Acceptable Asian Manufacturer (under the terms and conditions of a Receiver
License), from performing modifications or enhancements to the EchoStar Receiver
Software which do not require knowledge of and access to the Source Code.  Any
and all intellectual property rights which result from the development of the
modifications or enhancements (including any derivative works of the EchoStar
Software) hereunder by ABCN or an Acceptable Asian Manufacturer shall be
promptly disclosed and delivered to HTS and shall become and remain (at no cost
to HTS or other applicable EchoStar Affiliate) the sole and exclusive property
of HTS (or other applicable EchoStar Affiliate); provided, however, that
"EchoStar Software" and "Licensed Receiver Products" shall include such software
and products as modified or enhanced hereunder and each Acceptable Asian
Manufacturer shall receive a royalty free license to use such modifications and
enhancements for the sole purpose of manufacturing and selling Licensed Receiver
Products for use with the ABCN System in the Territory during the term of such
Acceptable Asian Manufacturer's Receiver License.

                                     -7-
<PAGE>

                   (b)  In the event that (i) HTS determines, acting in good
faith, that it will not be able to modify and adapt the EchoStar Receiver
Software in the manner required by Section 7.1 in sufficient time to enable ABCN
and the Acceptable Asian Manufacturers to commence manufacture of the Licensed
Receiver Products by the Delivery Date, or (ii) HTS is more than 90 days late
beyond any of the Delivery Dates or any Revised Delivery Date, ABCN shall have
the right to develop such modifications to the EchoStar Receiver Software
(including the Source Code thereof), either alone or in conjunction with one or
more Acceptable Asian Manufacturers which has a valid Receiver License in
effect.

                   (c)  In the event that HTS (or other applicable EchoStar
Affiliate) determines in good faith that a Request, as submitted to HTS (or
other applicable EchoStar Affiliate), cannot be developed or implemented for
valid technical reasons, or that it would be inadvisable to do so for technical
reasons, ABCN shall discuss in good faith with HTS (or other applicable EchoStar
Affiliate) the reasons for such determination.  In no event shall HTS (or other
applicable EchoStar Affiliate) be required to perform a modification or
enhancement which, in its good faith reasonable technical determination, which
has been fully explained to ABCN, is not capable of being performed or would
severely adversely affect the performance of the Licensed Receiver Products in
the Territory.

              7.3.  SOURCE CODE LICENSE.  HTS (or other applicable EchoStar
Affiliate) shall have no obligation to deliver Source Code to ABCN or any
Acceptable Asian Manufacturer except as expressly set forth in this Section 7.3.
Upon the occurrence of the events described in Section 7.2(b)(i) or (ii), HTS
(or other applicable EchoStar Affiliate) shall deliver to ABCN (or the
Acceptable Asian Manufacturer, depending on which entity made the Request for
which the services were not performed under the terms of Section 7), a copy of
such portions of the Source Code as is reasonably required to perform the
Request which HTS (or other applicable EchoStar Affiliate) declined or failed to
perform.  Subject to the provisions of Sections 4.1 and 4.2 above, concurrent
with such delivery of Source Code, HTS (or other applicable EchoStar Affiliate)
shall be deemed to have granted to ABCN, and ABCN shall be deemed to have
accepted, a limited, nonexclusive royalty-free right and license, either alone
or (as determined by ABCN) in conjunction with one or more of the Acceptable
Asian Manufacturers, to use a single copy of the Source Code at an ABCN or
Acceptable Asian Manufacturer facility identified to HTS solely for purposes of
developing such modifications.  As part of such right and license, ABCN and each
Acceptable Asian Manufacturer assisting with such modifications shall be
authorized to make and maintain one copy of the Source Code for backup and
archival purposes.  ABCN shall promptly notify HTS of each modification to the
Source Code developed by or for ABCN or an Acceptable Asian Manufacturer which
is implemented in a Licensed Receiver Product and shall furnish a complete copy
of the modified Source Code to HTS.  Such modifications shall be the proprietary
confidential information of HTS, and ABCN and the Acceptable Asian Manufacturer
shall be expressly prohibited from transferring or disclosing the Source Code to
any third party without the prior written authorization of HTS (which may be
withheld in HTS' absolute discretion) and shall disclose the Source Code to its
employees, agents and contractors on a strict need-to-know basis only.  ABCN and
each Acceptable Asian Manufacturer assisting with such modifications shall
maintain written records, which shall be available for inspection by HTS on
reasonable notice, of all such persons who have had access to the Source Code
and the period(s) of time for which such access was granted.  ABCN and each
Acceptable Asian Manufacturer assisting with such modifications shall expressly
advise each such person of the confidential nature of the Source Code and
applicable prohibitions on copying and disclosure.  For purposes hereof, the
term "Source Code" shall mean the Source Code for the EchoStar Receiver Software
related to the particular modifications to be made in accordance with this
Agreement, in the internally documented form actually used for development and
maintenance of the EchoStar Receiver Software, together with all software tools,
development aids and technical documentation possessed and owned by HTS which
are necessary or helpful in the modification and maintenance of the EchoStar
Receiver Software, but not including code subject to confidentiality or license
restrictions (in the case of Third-Party Software) precluding disclosure to
ABCN.  For payment as specified in Section 7.1(c), HTS will use commercially
reasonable efforts to support ABCN's and each Acceptable Asian Manufacturer's
efforts to modify the Source Code and will provide ABCN and each Acceptable
Asian Manufacturer assisting with such modifications with the names of persons
knowledgeable about and familiar with such Source Code to assist ABCN and such
Acceptable Asian Manufacturer with questions thereon.

         8.  OPTIONS.  Subject to the obligations of HTS hereunder, ABCN is
granting to ECC the Rights Options.

         9.  UNAUTHORIZED USE OF TECHNOLOGY; INDEMNIFICATION.

              9.1.  NOTIFICATION.  Each party shall notify the other party
promptly in writing of any actual or alleged unauthorized third party use or
misappropriation of the Software or the Licensed Receiver Products and shall
provide any available evidence thereof.

              9.2.  PROSECUTING MISUSE OR MISAPPROPRIATION.

                   (a)  HTS shall have the right, but shall not be obligated,
to prosecute at its own expense any such misuse or misappropriation of the
Software and Licensed Receiver Products, and HTS hereby agrees that ABCN may
join HTS as a party plaintiff in any such suit, at ABCN's expense.  The total
cost of any such action commenced or defended solely by HTS shall be borne by
HTS, and HTS shall keep any recovery or damages derived therefrom.

                   (b)  During the term of this Agreement, if HTS declines to
pursue a claim against a third party for misuse or misappropriation of the
Software and Licensed Receiver Products in the Territory within 60 days after
learning of the same, ABCN shall have the right, but shall not be obligated, to
prosecute at its own expense any such misuse or misappropriation of the Software
and Licensed Receiver Products in the Territory, and ABCN hereby agrees that HTS
may join ABCN as a party plaintiff in any such suit, at HTS's expense.  The
total cost of any such action commenced or defended solely by ABCN shall be
borne by ABCN, and ABCN shall keep any recovery or damages derived therefrom.

                   (c)  In the event ABCN and HTS jointly prosecute misuse or
misappropriation of the Software and Licensed Receiver Products in the Territory
by a third party, the parties shall each bear their own expense, and the costs
of any recovery shall be allocated (i) first to the payment of the parties'
expenses, on a proportional basis, and (ii) any award above the expenses shall
be divided fifty percent (50%) to ABCN and fifty percent (50%) to HTS.

              9.3.  INDEMNIFICATION BY HTS.  Subject to the provisions of
Section 10 below, HTS will, at its expense (including all costs of any appeal
bond), defend ABCN against, and pay all costs and damages made in settlement
approved by HTS in writing or awarded (by a final order of a court of
competent jurisdiction) against ABCN resulting from, any and all Claims (as
defined below) based on an allegation that the EchoStar Software or any
component of the Licensed Receiver Products infringes a U.S. patent,
copyright, trademark, trade secret or other proprietary right of any third
party, provided that ABCN (i) gives HTS prompt written notice of any such
Claim, (ii) allows HTS to direct the defense and settlement of the Claim, and
(iii) provides HTS with the information and assistance necessary for the
defense and settlement of the Claim.  If a final injunction is obtained in an
action based on any such Claim against ABCN's use of such EchoStar Software or
any such component of the Licensed Receiver Products by reason of such
infringement, or if in HTS's opinion such an injunction is likely to be
obtained, HTS shall either (a) obtain for ABCN the right to continue using the
EchoStar Software or the infringing component, or (b) provide such services as
may be necessary to modify the EchoStar Software or the infringing component
so that it becomes noninfringing.  For purposes of this Agreement, "Claims"
shall mean all demands, claims, actions or causes of action by third-parties
(other than Affiliates of ABCN) resulting in assessments, losses, damages
(including, without limitation, diminution in value), liabilities, costs and
expenses to ABCN or its Affiliates, including, without limitation, interest,
penalties and attorneys' fees and disbursements.

              9.4.  INDEMNIFICATION BY ABCN.  ABCN will, at its expense
(including all costs of any appeal bond), defend HTS against, and pay all costs
and damages made in settlement approved by ABCN in writing or awarded (by a
final order of a court of competent jurisdiction) against HTS resulting from,
any Claim based on an allegation that actions taken by ABCN to modify the
EchoStar Software or any component of the Licensed Receiver Products or to
include such EchoStar Software or component in another product produced by or on
behalf of ABCN, infringes an Asian patent, copyright, trademark, trade secret or
other proprietary right of any

                                     -9-
<PAGE>

third party, provided that HTS (i) gives ABCN prompt written notice of any
such Claim, (ii) allows ABCN to direct the defense and settlement of the
Claim, and (iii) provides ABCN with the information and assistance necessary
for the defense and settlement of the Claim.

              9.5. LIMITATIONS ON INDEMNIFICATION.  Notwithstanding the
foregoing provisions of this Section, the parties acknowledge that HTS is aware
of certain potential disputes or Claims of infringement described on SCHEDULE 6
regarding the portions of the EchoStar Software and the components described in
such SCHEDULE 6, and neither HTS nor ABCN shall have any indemnification
obligations with respect to any alleged or actual infringement by the portions
of the EchoStar Software and the components described in such SCHEDULE 6.  ABCN
acknowledges that the listing of any entity or technology on SCHEDULE 6 hereto
shall not be considered in any manner an admission by HTS or any Affiliate
thereof with respect to the intellectual property rights of any entity or to any
technology listed on such SCHEDULE 6.

         10.  LIMITATIONS OF LIABILITY.

         HTS's maximum liability to ABCN for violations or breaches of this
Agreement (other than fraud) shall not exceed an amount in U.S. dollars equal to
(i) (A) the lesser of $3.45 and the per share fair market value of one ABCN
share, MULTIPLIED BY (B) the 14,000,000 shares of ABCN that are subject to the
Rights Options (or, in the event that one or none  of the Receiver Licenses have
been entered into, 7,000,000 shares of ABCN), LESS (ii) the aggregate exercise
price for such shares under the Rights Option(s), where "fair market value"
shall be deemed for this purpose to equal (x) the average closing price of the
ABCN shares as reported with respect to the principal stock exchange or dealer
quotation system over which such shares have been traded for the then 20 most
recent trading days or (y) if the ABCN shares are not publicly traded, as
determined pursuant to the dispute resolution provisions set forth in Section 12
below.  IN NO EVENT SHALL EITHER PARTY BE LIABLE FOR LOSS OF PROFITS OR
INDIRECT, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES INCURRED BY THE OTHER
PARTY AND ARISING OUT OF OR IN CONNECTION WITH THIS AGREEMENT.  Each party
acknowledges that the limitations of liability set forth in this Agreement form
an essential basis of the bargain between the parties.

         11.  EXPORT MATTERS

         Compliance with the Export Administration Act of 1979, as amended, and
the regulations promulgated thereunder, in connection with the performance of
the terms of this Agreement and the Receiver Licenses, including obtaining the
necessary licenses and approvals for export of technology, shall be the sole
responsibility of HTS, and HTS shall use its best commercially reasonable
efforts to effect such compliance as soon as practicable.  ABCN shall reimburse
HTS for the costs of securing the necessary approvals and licenses for HTS's
performance of this Agreement and the Receiver License, and HTS agrees to use
legal counsel selected by ABCN for such efforts.

         12.  DISPUTE RESOLUTION

              12.1.  GOOD FAITH NEGOTIATIONS.  ABCN and HTS agree to attempt to
resolve any question or dispute that arises regarding or under this Agreement
through prompt good faith discussions between their respective officers with
decision-making authority.  The parties expressly acknowledge and agree that all
their respective obligations and responsibilities shall continue in full force
and effect during and despite the discussion of any dispute (other than any
dispute which has resulted in an attempt to terminate this Agreement as
evidenced by written notice of termination).  If the parties are unable to
resolve the dispute in a mutually satisfactory manner within thirty (30) days
from the date of the beginning of discussions, the matter may be submitted by
either party to arbitration as provided below.

              12.2.  BINDING ARBITRATION.  Any and all claims, disputes or
controversies arising under, out of, or in connection with this Agreement, which
have not been resolved by good faith negotiations between the parties, shall be
resolved exclusively by final and binding arbitration in Washington, D.C. USA,
under then current rules of the International Chamber of Commerce (the "ICC"),
by a three person arbitration panel.

                                     -10-
<PAGE>

ABCN and HTS shall each have the right to choose one of the arbitrators, and
the third arbitrator shall be mutually chosen from a list of arbitrators in
accordance with the ICC rules.  The arbitrators shall have no power to add to,
subtract from or modify any of the terms or conditions of this Agreement.

              12.3.  AWARD.  Any award made (i) shall be in writing and state
the arbitration panel's findings of fact and conclusions of law; (ii) shall be
made promptly, and in any event within sixty (60) days after the conclusion of
the arbitration hearing; and (iii) may contain an award of attorneys' fees for
the prevailing party in the interest of justice.  The costs of any arbitration
proceeding shall be equally divided between or among the involved parties, and
each party shall bear its own expenses, including attorneys' fees, unless
otherwise awarded by the arbitration panel.

         13.  TERM AND TERMINATION; REMEDIES.

              13.1.  TERM.  The term of this Agreement shall commence on the
date first written above and shall continue until terminated in accordance
with this Section 13 or elsewhere in this Agreement.

              13.2.  TERMINATION BY EITHER PARTY.  If either party shall cease
to carry on its business, this Agreement shall terminate effective upon
written notice by the party continuing in business to the party ceasing to
carry on its business.  All licenses and similar rights granted to ABCN in
this Agreement shall survive any termination of this Agreement by reason of
cessation of business by HTS and any other EchoStar Affiliate responsible for
development of the Software and Licensed Receiver Products.

              13.3.  WAIVER OF TERMINATION RIGHT.  In consideration of the
substantial investment required of ABCN in order to establish a DBS System in
the Territory, HTS hereby waives any right or remedies that HTS may have to
terminate this Agreement by reason of any material breach or default of this
Agreement by ABCN and acknowledges that HTS's sole and exclusive remedy shall be
recovery of damages by reason of any material breach or default of this
Agreement and equitable relief (including but without limitation temporary and
permanent injunctions); provided, however, that HTS may terminate this Agreement
and the Licenses granted herein upon written notice to ABCN in the event, and
only in the event, of the breach by ABCN or any Affiliate of its obligations
under the provisions of Sections 3.3, 4.1, 4.2, 7.3 and 14 which has or may be
reasonably expected to have a material adverse effect on HTS or the EchoStar
Affiliates.

              13.4.  TERMINATION RIGHTS OF HTS UPON A COMPETITOR ACQUISITION OF
ABCN.  Notwithstanding any of the foregoing provisions of this Section 13, in
the event of a Competitor Acquisition of ABCN (as defined below), HTS shall be
entitled upon thirty (30) days' written notice to ABCN, to terminate (a) the
Licenses granted to ABCN under Sections 3.3, 4.1, 7.2 and 7.3 hereof with
respect to EchoStar Software which is resident in the Licensed Receiver
Products, and (b) the access rights granted to ABCN under Section 3.2 hereof
with respect to information, documents and opportunities to confer with HTS
personnel which relate to Licensed Receiver Products.  The provisions of this
Section 13.4 shall not be construed to require any disassembly of hardware or
software resident in the ABCN System upon any termination of rights pursuant to
this Section 13.4 and shall not affect any License granted to an Acceptable
Asian Manufacturer under Section 6.  For purposes of this Section, a "Competitor
Acquisition of ABCN" shall mean an entity which is one of the principal direct
competitors of HTS or other EchoStar Affiliates in (i) producing Licensed
Receiver Products for use in the United States or (ii) providing direct to home
satellite services in the United States becoming the entity with the greatest
power, directly or indirectly, to direct the management and policies of ABCN on
a day-to-day basis (through the ownership of voting securities, by agreement or
otherwise).

         14.  CONFIDENTIALITY.  All information transmitted in writing, orally
or electronically, whether marked or indicated as "Confidential," received by
either party under this Agreement that is not known by, or generally available
to the public at large shall be deemed "Confidential Information" hereunder.
The recipient of Confidential Information will not, without the prior written
consent of the providing party, use any portion of the Confidential
Information for any purpose other than those contemplated by this Agreement,
and (i) will hold the Confidential Information in the strictest confidence,
(ii) will exercise the same care with respect thereto as it exercises with
respect to its own proprietary and confidential information, and will not,
without the providing

                                     -11-
<PAGE>

party's prior written consent, copy or disclose any portion thereof to any
third party other than as contemplated by this Agreement.  The foregoing shall
not prohibit or limit the recipient's use of information (including, but not
limited to, ideas, concepts, know-how, techniques, and methodologies) that
(which can be shown by written evidence): (a) is already known to it; (b) is
independently developed by it; (c) was received by the recipient on a
nonconfidential basis, prior to receipt from the providing party, from a third
party lawfully possessing and lawfully entitled to disclose such information
without restriction or obligation of confidentiality; or (d) becomes part of
the public domain through no breach by the recipient of this Agreement.  This
Agreement shall not be construed as granting or conferring any rights by
license or otherwise, expressly or implicitly, to the Confidential
Information, or any invention, discovery or improvement to the Confidential
Information, made, conceived or acquired prior to or after the date of this
Agreement.  The terms of the existing Confidentiality Agreement between
Affiliates of the parties to this Agreement are hereby incorporated herein as
if the Confidentiality Agreement had been signed by the parties to this
Agreement, and the scope of that Confidentiality Agreement is hereby extended
to include the matters contemplated by this Agreement.  Notwithstanding the
foregoing, each of the parties hereto shall be entitled to make any
disclosure: (a) required by any governmental authority, the stock exchange or
interdealer quotation system (such as Nasdaq), by law or regulations or at
court proceedings; (b) to the auditors, lawyers, investment bankers or other
representatives of the parties to this Agreement; (c) to the directors,
officers or employees of ABCN or HTS for the purpose of enabling them to
perform their duties; or (d) with the written consent of other party hereto.

hereto shall take or cause to be taken such further actions, shall execute,
deliver, and file or cause to be executed, delivered, and filed such further
documents and instruments, and shall obtain such consents as may be necessary or
as the other party may reasonably request in order fully to effectuate the
purposes, terms, and conditions of this Agreement.

              17.2.  ASSIGNMENT; AFFILIATES.  Neither party may assign its 
rights under this Agreement or any interest therein, or attempt to have any 
other person or entity assume its obligations under this Agreement, without 
the prior written consent of the other party hereto.  However, the parties 
agree that all rights granted to ABCN hereunder are also applicable, in whole 
or in part, to Affiliates of ABCN for use in connection with the ABCN System.  
The parties also agree that HTS shall draw upon the resources of the other 
EchoStar Affiliates as it deems reasonably necessary to perform its 
obligations hereunder.  HTS represents and warrants to ABCN that among the 
various EchoStar Affiliates, HTS is the EchoStar Affiliate with the ownership 
of or other rights to the EchoStar Software, Licensed Receiver Products, and 
other matters which are the subject of this Agreement or, to the extent HTS is 
not the owner or rights holder, HTS has obtained access to the personnel and 
resources of the applicable EchoStar Affiliates necessary for HTS to perform 
fully the obligations of HTS hereunder. To the extent that HTS is the 
possessor of the personnel, assets or knowledge necessary to perform any other 
EchoStar Affiliate's obligations under any of the other Transaction Documents, 
HTS shall make the same available to such other EchoStar Affiliate (without 
any cost to or obligation by ABCN) as necessary or appropriate for such other 
EchoStar Affiliate to perform such other obligations under such other 
Transaction Documents.  Each of ABCN and HTS may assign its rights and 
liabilities to an Affiliate, provided that ABCN and HTS shall remain 
responsible for their respective obligations hereunder, notwithstanding any 
such assignment.

              17.3.  NOTICES.  All notices, demands, requests, or other
communications which may be or are required to be given, served, or sent by any
party to any other party pursuant to this Agreement shall be in writing and

              17.4.  SEVERABILITY.  If fulfillment of any provision of this
Agreement or performance of any transaction related thereto, at the time such
fulfillment or performance shall be due, shall involve transcending the limit of
validity prescribed by law, then the obligation to be fulfilled or performed
shall be reduced to the limit of such validity; and if any clause or provision
contained in any Transaction Document operates or would operate prospectively to
invalidate any Transaction Document, in whole or in part, then such clause or
provision only shall be held ineffective, as though not herein or therein
contained, and the remainder of the Transaction Document shall remain operative
and in full force and effect.

              17.5.  WAIVERS.  No waiver by any party of, or consent by any 
party to, a variation from the requirements of any provision of this Agreement 
shall be effective unless made in a written instrument duly executed by or on 
behalf of such party, and any such waiver shall be limited solely to those 
rights or conditions expressly waived.

              17.6.  ENTIRE AGREEMENT; MODIFICATION; PRIORITY; BENEFIT.  This
Agreement and the other Transaction Documents constitute the entire agreement of
the parties hereto with respect to the matters contemplated herein, supersede
all prior oral and written memoranda and agreements with respect to the matters
contemplated herein (including without limitation the MOU), and may not be
modified, deleted or amended except by written instrument executed by the
parties.  All provisions of this Agreement shall be binding upon, and shall
inure to the benefit of and be enforceable by, the parties hereto and their
respective successors and permitted assigns.

              17.7.  TAXES.  Any and all payments required under this Agreement
to be made by one party (the "Paying Party") to the other party (the "Receiving
Party") shall be made free and clear of and without deduction or withholding for
any and all present or future non-U.S. taxes, levies, imposts, deductions,
charges or withholdings, and all liabilities with respect thereto (all such
taxes, levies, imposts, deductions, charges, withholdings and liabilities being
hereinafter referred to as "Taxes") unless such Taxes are required by law or the

                                     -14-
<PAGE>

administration thereof to be deducted or withheld.  If the Paying Party shall be
required by law or administration thereof to be deducted or withhold any Taxes
from or in respect of any sum payable hereunder, (i) the sum payable shall be
increased as may be necessary so that after making all required deductions or
withholdings (including deductions or withholdings applicable to additional
amounts paid under this Section) the Receiving Party receives an amount equal to
the sum it would have received if no such deduction or withholding had been
made, (ii) the Paying Party shall make such deductions or withholdings; and
(iii) the Paying Party shall forthwith pay the full amount deducted or withheld
to the relevant taxation or other authority in accordance with applicable law. 
Within 30 days after the date of any payment of Taxes, the Paying Party will
furnish to the Receiving Party a copy of a receipt evidencing payment thereof. 
The provisions of this section shall also apply to any amounts payable to any
Affiliate of HTS.

              17.8.  FORCE MAJEURE.  (a) If by reason of a Force Majeure (as
defined below), HTS or ABCN is unable, wholly or in part, to perform or comply
with its respective obligations hereunder, then both parties shall be relieved
of liability and shall suffer no prejudice for failing to perform or comply
during the continuance and to the extent of the inability so caused from and
after the happening of the event of Force Majeure, provided that the party
invoking the Force Majeure gives to the other party prompt notice, written or
oral (but if oral, promptly confirmed in writing) of such inability and
reasonably full particulars of the cause thereof.  If notice is not promptly
given then the parties shall only be relieved from such performance or
compliance from and after the giving of such notice.  The party invoking Force
Majeure shall use all reasonable efforts to remedy the situation and remove, so
far as possible and with reasonable dispatch, the cause of its inability to
perform or comply, provided, however, that settlement of strikes, lockouts and
other industrial disturbances shall be wholly within the discretion of the party
involved.  The party invoking Force Majeure shall give prompt notice of the
cessation thereof.  For greater certainty, if a party invokes Force Majeure to
excuse it from performance of an obligations hereunder, the other party shall be
relieved of its obligation to make any payment to the party invoking Force
Majeure on account of such obligation which is not being performed.

              (b)  The term "Force Majeure" shall mean any cause of any kind
whatsoever not within the control of a party and which such party could not, by
reasonable diligence, have foreseen or avoided, which may include without
limitation the following:  acts of God and the public enemy; the elements; fire;
accidents; breakdowns; vandalism; sabotage; breakage or accident to equipment;
satellite or equipment failure; the necessity of making repairs to equipment;
strikes; lockouts and any other industrial, civil or public disturbances; any
laws, orders, rules, regulations, acts or restraints of any government or
governmental body or authority, civil or military, including the orders and
judgment of courts; provided, however, that the term "Force Majeure" shall not
include the revocation or modification of any necessary governmental consent,
authorization or approval caused by a violation of the terms thereof or
consented to by the party holding such consent, authorization or approval.

              17.9.  GOVERNING LAW.  This Agreement, the rights and obligations
of the parties hereto, and any claims or disputes relating thereto shall be
governed by and construed in accordance with the laws of the State of New York
(but not including the choice of law rules thereof or the United Nations
Convention on Contracts for the International Sale of Goods).  

              17.10.  EXECUTION.  To facilitate execution, this Agreement and 
any of the other Transaction Documents may be executed in as many counterparts 
as may be required; and it shall not be necessary that the signatures of, or 
on behalf of, each party, or the signatures of all persons required to bind 
any party, appear on each counterpart; but it shall be sufficient that the 
signature of, or on behalf of, each party, or the signatures of the persons 
required to bind any party, appear on one or more of the counterparts.  All 
counterparts shall collectively constitute a single agreement.

preparation of the Site and shall have primary responsibility in connection
therewith and ExpressVu shall cooperate with HTS in the implementation of such
instructions.  The parties acknowledge that the timely preparation of the Site
is essential to the System Completion in the time set out in the GANTT Chart. 
HTS shall deliver the instructions to ExpressVu within 14 days of selection of
the Site by ExpressVu.  Upon receiving the instructions, ExpressVu shall at its
own expense prepare the Site in accordance with HTS' instructions.  HTS shall
notify in writing ExpressVu of any amendment to the instructions thereafter,
which notice shall not relieve HTS of its obligations with respect to attaining
System Completion in accordance with the GANTT Chart.  Notwithstanding the
foregoing, in the event that any amendment to the instructions shall, as
determined by ExpressVu and HTS acting together in good faith, result in the
delay of the System Completion in the times set out in the GANTT Chart and the
cause of such delay is not directly attributable to any fault of HTS in
connection with its obligations to provide instructions under this Section, then
the GANTT Chart shall be deemed to be amended accordingly to take into account
such delay and HTS shall not be liable to pay liquidated damages under Article
27 which would otherwise be payable as a result of such delay.  ExpressVu shall
prepare the Site so as to ensure that there will be, for the purpose of
installation of the Hardware, Software and the System:

     (a)  an adequate supply of electricity in accordance with the
          Specifications for the System or as otherwise directed by HTS by
          written notice to ExpressVu within a reasonable time prior to the
          installation of the System;

     (b)  adequate electrical and mechanical items and fittings in accordance
          with the Specifications for the System or as otherwise directed by HTS
          by written notice to ExpressVu within a reasonable time prior to the
          installation of the System;

     (c)  appropriate environmental conditions in accordance with the
          Specifications for the System or as otherwise directed by HTS by
          written notice to ExpressVu within a reasonable time prior to the
          installation of the System; and

<PAGE>

                                      -16-


     (d)  secure Site and storage areas for the various components of the
          Hardware.

8.4  HEALTH AND SAFETY.  ExpressVu shall take all reasonable precautions to
safeguard the health and safety of HTS' staff and sub-contractors working with
equipment and materials belonging to ExpressVu.  Furthermore, ExpressVu shall
ensure that such equipment and materials comply at all times with all relevant
statutory regulations and approved codes of practice.

8.5  OPERATING RECORDS.  During any applicable warranty period, ExpressVu shall
maintain operating records of the Encoders and copies of such records shall be
readily available to HTS, together with such additional information as HTS may
reasonably require.

8.6  PRIORITY FOR COMPLETION OF INTEGRATION SERVICES.  The parties acknowledge
that the EchoStar Parties have limited resources available for the completion of
the Integration Services.  The EchoStar Parties therefore covenant with
ExpressVu that they and their Affiliates shall give first preference and top
priority to the completion of the Integration Services for ExpressVu over the
completion of services similar to the Integration Services by the EchoStar
Parties or their Affiliates for any third party located in the Territory and, in
order to ensure that the Integration Services are completed on this basis,
further covenant that (i) the EchoStar Parties and their Affiliates will not
begin any other substantial systems integration undertaking in the Territory
prior to the completion of the Integration Services for ExpressVu and (ii) the
EchoStar Parties and their Affiliates shall not, prior to the completion of the
Integration Services, provide to a third party an aggregate of more than three
man weeks of work on any other substantial systems integration undertaking in
progress in the Territory as of the date of this Agreement.  Notwithstanding
anything to the contrary in the Agreement, the provisions of this Section 8.6
shall cease to apply on the earlier of (i) the 90th day after the invocation by
ExpressVu of Force Majeure to excuse it from the performance of any material
obligation under this Agreement if such Force Majeure has continued in effect
for 90 consecutive days, or (ii) December 31, 1997.

8.7  CESSATION OF INTEGRATION SERVICES.  If at any time prior to System
Completion, the EchoStar Parties determine in their good faith judgment that the
aggregate sum of the guarantees provided to the EchoStar Parties by ExpressVu's
shareholders pursuant to Section 32.2(b) (the "Guaranteed Amount") is within
U.S.$500,000 of their good faith estimate of the full amount of the Purchase
Price (including all adjustments thereto) which is due and payable or expected
to become due and payable on or before System Completion (the "Expected Purchase
Price"), the EchoStar Parties may, upon 14 days written notice to ExpressVu,
cease (i) the performance of all integration and other services to be rendered
by the EchoStar Parties in exchange for payment of the Purchase Price (including
all adjustments thereto); and (ii) the processing of orders for, and delivery to
ExpressVu of, all items to be supplied by the EchoStar Parties in exchange 

<PAGE>

                                      -17-


for payment of the Purchase Price (including all adjustments thereto), until
such time as the EchoStar Parties have received such satisfactory additional
financial assurances as are determined in the good faith discretion of the
EchoStar Parties (provided that, a guarantee of the amount by which the Expected
Purchase Price exceeds the Guaranteed Amount, substantially in the form of the
guarantee in Schedule 17, shall be deemed to be satisfactory) of such amounts
which the EchoStar Parties, acting in good faith, estimate are necessary to
fully cover the full amount of the Purchase Price (including all adjustments
thereto) which is due and payable or expected to become due and payable on or
before System Completion.  Notwithstanding the obligation of the EchoStar
Parties to give notice to ExpressVu as set out above, the EchoStar Parties shall
only be obligated to fulfil the obligations set out in clauses (i) and (ii)
above during such notice period until the point in time at which the EchoStar
Parties, acting reasonably, estimate that the expenditures of ExpressVu for the
fulfilment of such obligations by the EchoStar Parties are equal to the
Guaranteed Amount or, with the fulfilment of the next step in the Integration
Services, would exceed the Guaranteed amount.  In no event shall the EchoStar
Parties be liable for any liquidated damages or any other amount whatsoever for
delays in System Completion resulting from the exercise of their rights under
this Section 8.7 provided that, after amendment of the GANTT Chart by mutual
agreement of the parties to adjust for the delay caused by a cessation of
activities in accordance with this Section, nothing in this Section shall be
construed as reducing the obligations of the EchoStar Parties to attain System
Completion by such time as is established by such revised GANTT Chart.

                               ACCEPTANCE TESTING

9.1  SKILLED PERSONNEL AND CONSULTANTS.  The parties shall make available
suitably skilled personnel and consultants to conduct the Acceptance Test
Procedures on the System as stipulated in Schedule 5 for each milestone of the
GANTT Chart.

9.2  TIMELY MANNER.  HTS shall use its commercially reasonable efforts to
conduct the Acceptance Test Procedures in a timely manner in co-operation with
ExpressVu within the timeframe established in the GANTT Chart, provided that HTS
shall be primarily responsible for ensuring that they are correctly carried out.

9.3  FAILURE.  If the System fails to pass any one or more of the acceptance
tests established in accordance with Schedule 5, then HTS shall remedy all
material defects which are the cause of such failure except if:

     (a)  the defect is caused by a Customer Modification or is attributable to
          alterations or modifications to the System not authorized in writing
          by HTS;

<PAGE>

                                      -18-


     (b)  the defect is the result of the use by ExpressVu of the Conditional
          Access System other than in the operating environment reasonably
          recommended by HTS; or

     (c)  the defect is the result of ExpressVu's failure to meet an obligation
          under this Agreement;

in which circumstances HTS shall notify ExpressVu as soon as reasonably
practicable after it becomes aware that the defect is so caused.

9.4  NOTICE.  ExpressVu shall be given reasonable prior notice of the
commencement of, and the reasonable opportunity to observe, all Acceptance Tests
Procedures being conducted under this Article.
 
9.5  ACCEPTANCE CERTIFICATES.  

     (a)  Upon ExpressVu being satisfied that any Acceptance Test Procedures
          detailed on the GANTT Chart have reached Successful Completion,
          ExpressVu shall verify its acceptance as indicated by the signature of
          a duly appointed representative of ExpressVu on an Acceptance
          Certificate, such approval and signature to be promptly provided and
          not to be unreasonably withheld, and if reasonably withheld notice
          thereof with specific reasons for withholding shall promptly be
          provided to HTS.  In the event it is determined under arbitration
          hereunder that approval should have been provided by ExpressVu in the
          circumstances, ExpressVu shall, in addition to all remedies available
          to HTS available at law, pay interest on any payment due at a rate of
          24% per annum from the date due until such payment obligations are
          satisfied in full.  ExpressVu acknowledges that the Successful
          Completion of the Stat Muxing system shall be later and not form a
          part of the acceptance of the System Completion.

     (b)  Notwithstanding anything else herein contained, an acceptance test
          shall be deemed to have been passed, and ExpressVu shall issue an
          Acceptance Certificate in respect thereof, if the results of the test
          demonstrate that the System (or the component thereof subject to any
          particular Acceptance Test Procedures) is performing in all material
          respects at least as well as the system used by EchoStar to provide
          its DTH Service.

                            SYSTEM PRICE AND PAYMENT 

10.1 PRICE AND TERMS.  Subject to the obligations of HTS hereunder, ExpressVu
shall pay, as full and complete consideration (subject to adjustment as
otherwise provided for herein) for the purchase of the Hardware, the license of
the Software and the provision of Integration Services, the amounts based on the
unit costs as described in Schedule 2 and summarized in Schedule 9, F.O.B.
California (the "Purchase Price").  The Purchase Price shall be paid by
ExpressVu to HTS as follows:

     (a)  25% of the Purchase Price on the Effective Date; 

     (b)  65% of the Purchase Price in periodic payments five Business Days
          prior to the date HTS is required to make corresponding payments to
          any of its contractors or suppliers who are providing any item
          required to be delivered by HTS hereunder or performing on behalf of
          HTS any of the Integration Services provided that (i) no such periodic
          payment shall be required to be made except to the extent of the value
          of any such item delivered to the Site or work performed and (ii) HTS
          shall give ExpressVu five Business Days' notice of any payment
          required pursuant to this Section 10.1(b) together with appropriate
          documentation relating thereto; 

     (c)  9% of the Purchase Price (the "Penultimate Instalment") on System
          Completion or if System Completion is delayed due to the fault of
          ExpressVu, such earlier date as System Completion would have been
          achieved had ExpressVu not delayed HTS in achieving System Completion
          provided that if having received payment of the Penultimate Instalment
          HTS subsequently fails (through no fault of ExpressVu) to achieve
          System Completion on the date to which its obligation to so complete
          is extended due to the fault of ExpressVu, it shall forthwith
          reimburse to ExpressVu the Penultimate Instalment and ExpressVu shall
          not thereafter be required to repay the Penultimate Instalment to HTS
          until System Completion is achieved; and

     (d)  1% of the Purchase Price on the date of the Acceptance Certificate in
          respect of Stat Muxing or if issuance of such Acceptance Certificate
          is delayed due to the fault of ExpressVu, such earlier date as it
          would have been issued had ExpressVu not delayed HTS in achieving
          completion of the Stat Muxing. 

10.2 PRICE EXCLUSIONS.  Unless otherwise agreed in writing, the Purchase Price
is exclusive of delivery, freight, insurance and packaging costs and all other
applicable taxes, duties, imposts or similar charges (including without
limitation any export or 


<PAGE>
                                    -20- 

import duties).  In the event that such taxes, duties, imposts or similar
charges become due, these will be for ExpressVu's sole account, provided that
ExpressVu will not in any circumstances be liable to pay any taxes on the income
or profits of HTS.  Invoices in respect of amounts payable under this Section
shall be paid by ExpressVu forthwith upon receipt of the invoice by ExpressVu.

10.3 FUTURE SERVICES.  HTS acknowledges that as a result of the successful
implementation of the System, ExpressVu will be dependent on continued access to
and support of the various components and services of HTS and its suppliers,
including Nagra and DiviCom for the supply of Smart Cards, the Conditional
Access System and Encoders, respectively, and in connection therewith, ExpressVu
intends to enter into long term support and maintenance agreements with each of
Nagra and DiviCom.   Notwithstanding such contractual relationships between
ExpressVu and Nagra and DiviCom, HTS shall use its commercially reasonable
efforts to provide all necessary support services at its Standard Rates to
ensure the continued integration of the components of the System for a minimum
of two years from the date hereof.

10.4 CHANGE OF TECHNOLOGY.  

     (a)  If at any time during the term of this Agreement, the EchoStar Parties
          determine to change the basic technology relating to either set top
          boxes or the uplink centre they employ to provide ESC's DTH Service in
          the United States, they will advise ExpressVu of such decision and, at
          ExpressVu's option, either (i) use their commercially reasonable
          efforts to ensure ExpressVu is able, at ExpressVu's sole cost and
          expense, to make the same change in technology, or (ii) ensure that
          appropriate arrangements are in place to provide ExpressVu with the
          right to use and modify the HTS Software in the event that HTS at any
          time ceases to support and further develop the HTS Software. 

     (b)  ExpressVu may cease to use the basic technology relating to either set
          top boxes or the uplink centre it employs to provide its DTH Service,
          other than as a result of a decision made by the EchoStar Parties
          under Section 10.4(a), only (i) after the second anniversary of the
          date of this Agreement, and (ii) in accordance with the terms of this
          Section 10.4(b).  ExpressVu's decision hereunder shall be made in good
          faith only on the basis that the technical functionality of the new
          technology provides substantial performance gains for ExpressVu and
          only after ExpressVu has, no less than 14 days prior to making such a
          decision, provided to HTS (to the extent allowed under any third party
          agreement to which ExpressVu is a party, after reasonable efforts by
          ExpressVu to ensure that it can do so), a written analysis describing
          such functionality and performance gains and HTS, if it so chooses,
          has supplied (and ExpressVu has considered), a 


<PAGE>
                                    -21- 

          written rebuttal by HTS to such analysis.  ExpressVu, after
          considering any such rebuttal and determining that it wishes to
          proceed with such technology change, will immediately advise the
          EchoStar Parties of such decision in writing (a "Technology Change
          Notice") and ExpressVu will use its commercially reasonable efforts to
          ensure that ESC is able, at ESC's sole cost and expense, to make the
          same change in technology and that HTS is granted a non-exclusive
          right to manufacture set top boxes based on such technology. ESC shall
          have the option, for a period of 30 days after receiving a Technology
          Change Notice, to terminate this Agreement upon not less than 90 days
          written notice to ExpressVu, and ESC may, at its option and
          concurrently with exercising such right of termination, require
          ExpressVu to purchase any equity interest in ExpressVu, or any
          successor thereof, then held by ESC or an Affiliate thereof for a
          purchase price equal to the fair market value thereof at such time,
          such fair market value to be determined by a firm of chartered
          accountants or business valuators to be mutually agreed by ESC and
          ExpressVu.

     (c)  For the purposes of this Section 10.4, "basic technology" means the
          technology which makes possible the transmission, processing and
          reception of programming signals to Boxes, including, without
          limitation, the Software and Hardware but for the purposes of this
          definition a changeover from FSS to DBS will not be considered a
          change in basic technology.

10.5 FAILURE TO PAY BY DUE DATE.  If ExpressVu fails to pay any sum owed when
due in accordance with Section 10.1 and such payment default is not remedied
within 15 Business Days of being notified in writing of such default by
EchoStar, HTS shall have the right, without prejudice to its other rights or
remedies hereunder, to cancel delivery in respect of any Hardware or Software
due to be delivered or may suspend further contractual performance in respect of
which ExpressVu is in default of payment.

10.6 PURCHASE PRICE ADJUSTMENTS IN CERTAIN CIRCUMSTANCES.  In the event that the
EchoStar Parties cannot provide the benefit of any third party warranty, license
or indemnity in respect of any component of Hardware or Software being supplied
by a third party, ExpressVu may, in its sole discretion, purchase such component
directly from its manufacturer and the Purchase Price shall be reduced according
to the amount specified for such item in Schedule 9, provided that, for the
purposes of Section 27.1 only, the amount of any such adjustment shall continue
to be included in the Purchase Price.  For greater certainty, any such
adjustment in the Purchase Price made in accordance with this Section shall not
affect the amount payable by ExpressVu in respect of Integration Services under
Schedule 9.

                             BOX STANDARDS/APPROVALS

11.1 STANDARDS.  

     (a)  The Boxes to be provided by HTS hereunder shall be identical to the
          "Baker" set top boxes used by HTS to make available its DTH Service to
          its subscribers or, subject to HTS having the necessary rights to do
          so (which rights HTS shall use its commercially reasonable efforts to
          obtain), any other model of set top box that is at such time widely
          distributed by HTS in the United States (provided that, for greater
          certainty, any such set top box shall be backward compatible with
          existing Smart Cards and Boxes provided to Subscribers to ExpressVu's
          DTH Service) except that:

          (i)   the Boxes will have dual FSS/DBS capability; 

          (ii)  the Boxes will be capable of functioning as an FSS set top box
                which can be converted into a DBS functioning set top box (such
                conversion to take place by way of software modification using
                data signals downloaded to the Box from ExpressVu's DTH 
                Service); and 

          (iii) the Boxes will have received all necessary approvals for sale 
                in Canada as required by Section 11.2. 

     (b)  In addition to its obligations under Section 11.1(a), HTS will use its
          commercially reasonable efforts to make available in Canada for use in
          ExpressVu's DTH Service such other upgraded set top boxes as HTS may
          at any time be making available for sale to consumers in the United
          States subject to HTS having the necessary rights to do so (which
          rights HTS shall use its commercially reasonable efforts to obtain).

     (c)  For greater certainty, ExpressVu recognizes that it may be required to
          change the Outdoor Units and LNBs at its cost when it moves its DTH
          Service from an FSS satellite to a DBS satellite.

11.2 APPROVALS.  HTS shall obtain all necessary regulatory approvals for the
design and manufacture of the Boxes and the Smart Cards and the sale of the
Boxes and the Smart Cards in the Territory (including, without limitation, any
requirements imposed by Industry Canada or Underwriters Laboratory Canada (ULC))
prior to System Completion.

                                  MANUFACTURING

12.1 MANUFACTURE OF BOXES, SMART CARDS AND OUTDOOR UNITS.  Subject to the terms
and conditions contained herein, HTS shall manufacture, or cause to be
manufactured, Boxes, Smart Cards and Outdoor Units for use by Subscribers to
ExpressVu's DTH Service.  

12.2 SUB-LICENSE.  ExpressVu acknowledges that the Box design is proprietary to
HTS and the Box incorporates certain Intellectual Property Rights of HTS.  At
the request of ExpressVu, HTS shall, to the extent that it is within HTS' power
to do so (after using its commercially reasonable efforts to obtain the rights
to do so), grant to third parties all of the rights necessary to manufacture
Boxes, the EPG and Outdoor Units for use by Subscribers to ExpressVu's DTH
Service provided that any such third party:

     (a)  executes HTS' standard manufacturing license agreement, the principal
          terms of which shall be no more onerous than those set forth in
          Schedule 12 attached hereto; 

     (b)  either pays HTS a one-time license fee which shall not exceed
          U.S.[CONFIDENTIAL MATERIAL REDACTED] during 1997 or 1998 (and any
          increase thereafter shall not exceed increases in the "United States
          Bureau of Labor Statistics Indices SIC Code 3761 for Guided Missiles
          and Space Vehicles, Average Hourly Earnings" after 1998) or agrees to
          pay HTS a per unit licensing fee negotiated by such third party and
          HTS; 

     (c)  is not engaged in the business of providing a DTH service in the
          United States and does not own, directly or indirectly, more than 20%
          of the equity shares of any corporation which is engaged in the
          business of providing a DTH service in the United States and is not an
          Affiliate of any person engaged in the business of providing a DTH
          service in the United States; and  

     (d)  is able to meet such manufacturing quality standards as may reasonably
          be required by HTS.  

12.3 HTS RIGHT OF SUBSTITUTION.  Notwithstanding that any particular third party
may otherwise satisfy the conditions set forth in Section 12.2, HTS may refuse
to grant such third party manufacturing rights pursuant thereto provided that
HTS has reasonable commercial grounds for such refusal and further provided that
in such event HTS and ExpressVu will jointly use their commercially reasonable
efforts to arrange for another third party manufacturer of worldwide stature
that has acceptable distribution capability in 

<PAGE>
                                      -24- 

the Territory to manufacture Boxes, the EPG and Outdoor Units for use by
Subscribers to ExpressVu's DTH Service. 

12.4 SPECIFICATIONS AND QUANTITIES.  Throughout the term, HTS shall manufacture
or cause to be manufactured all Boxes, Outdoor Units and Smart Cards in
accordance with the Specifications, as may be amended from time to time by HTS
allowing for backward compatibility with the System, in such quantities as are
necessary to satisfy the monthly supply requirements imposed upon HTS hereunder
as set forth in the Forecast.  HTS shall provide for the sourcing and stocking
of Outdoor Units with 60 and 75 cm. diameter antennas and LNBs with a .8 dB
noise performance or LNBFs with a 1.1 dB noise performance.  Subject to the
provisions of Section 14.9, HTS shall make available sufficient numbers of
Outdoor Units to match the sale of the Boxes as determined in the Forecast.

12.5 MODIFICATIONS.  In the event that a failure of the Satellite Infrastructure
necessitates a modification to the Boxes, HTS will carry out the necessary
modifications to the Boxes at the request and sole expense of ExpressVu. 
Modifications carried out by HTS in accordance with this Section will be charged
to ExpressVu at HTS' Standard Rates and the Purchase Price will be adjusted
accordingly.

12.6 SMART CARD FLOAT.  HTS shall supply ExpressVu at the Smart Card Price with
a float of Smart Cards to replace Smart Cards which are reported by Subscribers
as having been lost, stolen or broken in a quantity per 1,000 Subscribers
consistent with the Smart Card replacement history of EchoStar's DTH Service. 
HTS shall provide replacement Smart Cards in excess of such quantity provided
that ExpressVu can adequately justify its need therefor for purposes permitted
pursuant to this Agreement.

12.7 PACKAGING AND LABELLING.  HTS shall, at its expense, ensure that all
packaging and labelling of the Boxes, Smart Cards and Outdoor Units conform to
the Specifications and in all respects with the requirements of Canadian law,
rules and regulations, including, without limitation, bar code identification,
bilingual labels (which bilingual labels, notwithstanding the foregoing, shall
be provided at ExpressVu's expense), serial number identification or lot control
coding as applicable, and shall provide the same packaging and protective
material used by HTS from time to time in the U.S. market intended to protect
against product damage in normal shipping and handling conditions.  For greater
certainty and notwithstanding anything else herein contained, ExpressVu shall be
responsible for providing HTS, at ExpressVu's cost, with a French language
version of any English language instruction manuals provided by HTS for the
Boxes and Outdoor Units and bilingual labels.  Except as required by Canadian
law, rules and regulations, the Boxes and Outdoor Units shall bear the same
logos and have the same look as those used by HTS in the United States.

13.1 APPOINTMENT.  ExpressVu hereby appoints HTS as ExpressVu's non-exclusive
distributor of Boxes, Smart Cards and Outdoor Units throughout the Territory and
HTS hereby accepts such appointment.  Subject to the provisions of this
Agreement, ExpressVu confers upon HTS the non-exclusive rights and
responsibilities to sell and distribute the Boxes, Smart Cards and Outdoor Units
within the Territory.  HTS may appoint distributors and dealers of the Boxes,
Smart Cards and Outdoor Units in the Territory provided that any such
distributor is not a competitor of ExpressVu's and such distributor is otherwise
approved by ExpressVu, such approval not to be unreasonably withheld.  

13.2 INCREASING SALES.  During the term of this Agreement, HTS shall diligently
and faithfully fulfil its obligations hereunder and shall use reasonable efforts
to further increase the sale of the Boxes and ExpressVu's DTH Service to benefit
the mutual business interests of ExpressVu and HTS by the methods described in
the Marketing Plan.  In furtherance of this obligation, but without limitation,
HTS agrees to:

     (a)  maintain an adequately trained and effective sales force of adequate
          size to effectively represent and promote the sale of the Boxes and
          Outdoor Units to customers in the Territory; and

     (b)  provide sales literature, product literature and other appropriate
          promotional materials to ExpressVu's customers and personnel. 

13.3 DISTRIBUTION.  HTS shall distribute the Boxes, Smart Cards and Outdoor

with ExpressVu's effort to sell and distribute its DTH Service throughout the
Territory.  Immediately upon commencing its distribution responsibilities
hereunder, HTS shall distribute Boxes, Smart Cards and Outdoor Units to those
distributors and dealers it is mutually agreed by ExpressVu and HTS should be
granted rights to sell Boxes, Smart Cards and Outdoor Units in the Territory. 
For greater certainty, HTS shall not be required to extend credit to any
distributor or dealer except upon such terms and conditions as it may, in its
sole discretion, determine and HTS shall not be required to supply any dealer's
or distributor's order which is for less than 60 Boxes, Smart Cards and Outdoor
Units.

promotion of the Boxes, Outdoor Units and ExpressVu's DTH Service in the

13.6 PRICES AND BOX SUPPLY.    

     (a)  [CONFIDENTIAL MATERIAL REDACTED] 


     (b)  In the event that ExpressVu, after reasonable notice and time to cure
          being provided to HTS (such period not to exceed 60 days in the
          aggregate), is unsatisfied with any aspect of the sales and
          distribution services being provided by HTS, including, without
          limitation, lack of sales and distribution penetration of the Boxes
          and Outdoor Units in all regions of the Territory or ineffective sales
          or distribution performance, HTS shall throughout the remainder of the
          term hereof, sell and supply to ExpressVu and/or its appointed
          distributor for re-sale Boxes and Outdoor Units at prices not
          exceeding the prices then being charged by HTS to distributors
          purchasing like quantities of Boxes and Outdoor Units on like terms
          and conditions as ExpressVu and/or its appointed distributor wishes to
          purchase the same. 

13.7 PRICES TO DISTRIBUTORS AND DEALERS.  Subject to Section 13.6(a) and
excluding later generation Boxes with additional features supplied by HTS
pursuant to its obligations under Section 11.1(b) (the prices for which will be
mutually agreed upon by the parties), the prices to be charged by HTS for Boxes
and Outdoor Units to distributors and dealers in the Territory purchasing not
less than 60 Units per order shall not exceed those set forth in Schedule 17
attached hereto.  HTS shall further ensure that the prices for Boxes and Outdoor
Units charged to distributors and dealers in the Territory do not exceed the
prices from time to time charged by HTS to distributors in the United States or
Canada purchasing like quantities of set top boxes and outdoor units on like
terms and conditions as any distributor in the Territory which wishes to
purchase Boxes and Outdoor Units.  Notwithstanding the foregoing, if HTS
subsidizes the price of the Boxes, the provisions of this Section 13.7 shall not
apply.  For greater certainty, all prices referred to in this Section 13.7 are
F.O.B. at point of shipment.

13.8 PRICE CHANGES.  HTS shall communicate all price changes in writing to all
distributors and dealers of the Boxes, Smart Cards and Outdoor Units.  Without
limiting the generality of the foregoing, HTS shall provide at least 30 days
notice of any permitted price increases.

ExpressVu, on a shipment by shipment basis, information relating to the serial
numbers of each Box shipped into the Territory by HTS and/or other manufacturers
and shall keep 

<PAGE>

and supply to ExpressVu the names and addresses of the first purchasers of each
Box in the Territory.  ExpressVu shall supply to HTS on a monthly basis, records
of the number of new Subscribers received by ExpressVu in the Territory
reconciled to the serial code of the serial numbers of the Boxes.  ExpressVu
shall throughout the term of this Agreement provide details to HTS on the number
of Boxes ordered by ExpressVu from any other source and shall provide to HTS
Smart Card serial numbers together with the serial numbers of the Boxes to which
they are mated in the event ExpressVu is entitled to purchase Smart Cards from
other sources pursuant to Section 14.8.  

13.10 UPGRADING.  HTS may from time to time during the term of this Agreement 
upgrade the Smart Cards with regard to their functionality and security.  
Unless the upgrade is part of a security measure, such upgraded Smart Cards 
will be backward compatible with existing Smart Cards and Boxes provided to 
Subscribers to ExpressVu's DTH Service. 

13.11 PERSONALIZATION DATA.  Each Smart Card shall be Personalized for 
ExpressVu as directed by HTS by setting the following data as dictated by 
ExpressVu:

      (a)  vendor identity;

      (b)  Smart Card serialization;

15.1 CUSTOMER WARRANTY.  HTS hereby covenants that it will provide to purchasers
of the Units the same warranties it provides to purchasers of such products in
the United States provided that HTS shall not be required to extend the term of
any such warranties beyond a period of 90 days from the date of purchase. 

15.2 BREACH OF CUSTOMER WARRANTY.  HTS shall provide quarterly reports of all
warranty returns for the Units.  After a period of six (6) months from the Final
System Acceptance Date, in the event that the failure rate for returns on Units
under customer warranty on an annualized basis exceeds 10% percent of all Units
shipped to such date in the Territory, the defect for which is not identified
and remedied by HTS within 45 days of notice thereof by ExpressVu, then HTS
shall waive the U.S.$250,000 license fee with respect to the first third party

17.1 REPAIR FACILITIES.  HTS shall specify and describe to ExpressVu, within 90
days of the date hereof, repair service centre facilities to be used for both
warranty and out-of-warranty equipment repairs and service and which will be
available to Subscribers. 

17.2 REPAIR PROGRAM.  HTS shall forthwith develop for approval by ExpressVu (and
in no case later than 90 days from the date hereof) a service centre repair
program that defines:

     (a)  the number and location(s) of manufacture designated repair centres;

     (b)  provision for setting up authorized repair centre agents;

     (c)  process for repair and service;

     (d)  policy and plan for providing Subscribers with immediate replacement
          of Units while Subscribers' Units are being serviced or repaired; and

17.3 SUPPORT SERVICES.  

     (a)  At ExpressVu's request, HTS shall provide at HTS' facilities such
          training of ExpressVu personnel as may be reasonably required to
          permit ExpressVu to provide technical support service to its
          Subscribers.  Such training shall be provided at no charge to
          ExpressVu except that ExpressVu shall bear the travel and living
          expenses of such personnel.  

     (b)  If the technical know-how required by an HTS technical service
          representative (a "TSR") to effectively advise an ExpressVu TSR is
          substantially similar to the technical know-how required by an HTS TSR
          to provide advice with respect to ESC's DTH Service, HTS shall at all
          times make TSRs available to ExpressVu by telephone at a cost of
          U.S.$2.00 a minute (subject to adjustment for increases in HTS' costs
          for such personnel).  If the technical know-how required by an HTS TSR
          to effectively advise an ExpressVu TSR is not substantially similar to
          the technical know-how required by an HTS TSR with respect to ESC's
          DTH Service, HTS shall make HTS TSRs available to ExpressVu by
          telephone on terms mutually agreeable to the parties (subject to
          adjustment for increases in HTS' costs for such personnel).

     (c)  Emergency support services shall be provided by HTS to ExpressVu at
          Standard Rates.  In that regard, HTS shall provide ExpressVu with a
          list of key contact support personnel who may be contacted by
          ExpressVu on a 24-hour, 365-day basis for troubleshooting purposes.

                                SIGNAL PROTECTION

18.1 SIGNAL SEPARATION.  ExpressVu and ESC acknowledge that there is a
significant threat of members of the public in one jurisdiction attempting to
subscribe to the DTH Service provided by the other party from the other
jurisdiction.  ExpressVu and ESC shall cooperate throughout the term hereof in
preventing members of the public from the other's jurisdiction subscribing to
its DTH Service.  To such end, ESC and ExpressVu hereby agree to achieve the
separation of broadcasting signals by cooperating together in respect of the
following (provided that, for greater certainty, each of the parties'
obligations under this Section 18.1 shall be limited to the extent of such
party's reasonable technical capability to perform any of the following and
further provided that each party shall use its commercially reasonable efforts
to perform the following):

     (a)  ExpressVu shall provide to ESC a monthly list (including names,
          addresses and telephone numbers) of all requests for subscriptions to
          its DTH Service

<PAGE>

                                      -32-


          from customers providing a U.S. telephone number (or identified as
          being in the U.S. via an automatic number identification), address
          and/or residency or other U.S. data, and shall refer such requests for
          service to EchoStar;

     (b)  ESC shall provide to ExpressVu a monthly list (including names,
          addresses and telephone numbers) of all requests for subscriptions to
          its DTH Service from customers providing a Canadian telephone number
          (or identified as being in Canada via an automatic number
          identification), address and/or residency or other Canadian data, and
          shall refer such requests for service to ExpressVu;   

     (c)  to ensure that no Boxes intended for use in ExpressVu's DTH Service
          are mated with a Smart Card intended for use in ESC's DTH Service and
          vice-versa, ExpressVu and ESC shall, as stated in Section 13.9, keep
          and supply to each other serial numbers of Boxes (whether such Boxes
          are manufactured by HTS or by a third party licensed by it) and Smart
          Cards in the Territory, and shall permit independent audits by
          recognized accounting firms of each other's records for compliance
          purposes provided that reasonable notice of a party's intention to
          have such audit performed shall be provided to the other party and any
          such audit shall be conducted in a manner so to minimize disruption of
          normal business of the party whose records are being audited;

     (d)  ExpressVu and ESC shall keep a record of all telephone calls received
          (including those received during set top "polling") by their
          respective call centres or by a call collector at their respective
          uplink centres and identified as being placed from the jurisdiction of
          the other and shall supply such information to the other on a monthly
          basis;

     (e)  ExpressVu and ESC shall keep a record of all telephone numbers and
          addresses of every subscriber within their own jurisdiction having
          four or more subscriptions for one telephone number or street address,
          and each of ESC and ExpressVu shall provide such records to the
          independent auditor so as to determine the residency of such
          subscribers;

     (f)  ExpressVu and ESC shall use reasonable commercial efforts to
          investigate the residency of any of their respective subscribers
          having the same telephone numbers or address as four or more other of
          their subscribers and each shall provide the conclusions of such
          reports to the other; 

     (g)  ExpressVu and ESC shall use reasonable commercial efforts to ensure
          that design and implementation of the end-to-end security system
          minimizes the 

<PAGE>

                                      -33-


          ability of any subscriber to purchase a Box or ESC's set top box in
          one country and obtain programming services from the other country;

     (h)  ExpressVu and ESC shall use reasonable commercial efforts to ensure
          that Smart Cards intended to provide subscribers with access to one of
          the party's DTH Service cannot also be used to provide subscribers
          with access to the other party's DTH Service;

     (i)  ExpressVu and ESC shall use reasonable commercial efforts to ensure
          that Smart Cards which are lost, stolen or damaged may be replaced
          without the need to replace the Box; and

     (j)  notwithstanding the foregoing and without detracting from the other
          obligations of ESC contained in this Section, ExpressVu and ESC agree
          that ESC shall not be obliged to provide ExpressVu with a list of such
          subscribers to ESC's DTH Service, who would fall under the provisions
          of this Article 18 and who were subscribers as at the date of this
          Agreement, until the first anniversary of the date of this Agreement.

18.2 SHUT-OFF INDEMNITY.  Upon either of ESC or ExpressVu determining that a
subscriber in the jurisdiction of one is subscribing to the service in the
jurisdiction of the other, the aggrieved party may require that the other party
terminate the signal subscription to such subscriber whereupon the requesting
party shall indemnify and hold the party terminating the service harmless from
any claims, damages or costs in respect of the subscriber whose service has been
terminated if it is subsequently determined that such subscriber is in fact not
in the jurisdiction of the aggrieved party.  Notwithstanding the foregoing, the
provisions of this Section 18.2 shall not (i) take effect until the date on
which ExpressVu commences to provide its DTH Service to Subscribers in the
Territory and (ii) apply to Specialty Language Subscribers.

18.4  AUDIT.  Either ESC or ExpressVu (the "Auditing Party") may, through a
nationally recognized independent accounting firm, upon reasonable prior written
notice to the other (the "Audited Party"), obtain access to the records of the
Audited Party during normal business hours for the purposes of determining the
Audited Party's compliance with obligations undertaken in this Agreement,
including without limitation the anti-grey marketing provisions of the foregoing
provisions of this Article 18 and the restrictions imposed on the Audited Party
with respect to set top box and Smart Card security; provided however, that: (i)
the audit shall not unreasonably disrupt the normal business operations of the
Audited Party; (ii) the Audited Party shall not be under any obligation to
disclose information to the Auditing Party which is subject to confidentiality
restrictions imposed by a third party; (iii) audits may not take place more than
once per 12 month period, unless such restriction is waived in writing by the
Audited Party; and (iv) the Auditing Party shall bear all expenses in connection
therewith, except that if the audit reveals the Audited Party to not be in
compliance with its obligations hereunder in any material respect in which case
the Audited Party shall bear all reasonable expenses of such audit. 

18.5 GREY MARKETING-DISTRIBUTORS AND DEALERS.  

     (a)  The EchoStar Parties shall use their commercially reasonable efforts
          to obtain the agreement of their existing distributors and dealers
          that they will not directly or indirectly sell Units or programming
          into Canada (and shall obtain the agreement of all such future
          distributors and dealers to so comply with such provisions) so as to
          preclude such distributors and dealers from, directly or indirectly,
          offering for sale set top boxes and/or programming intended for use in
          the United States by subscribers to ESC's DTH Service to Persons
          resident in Canada.  

     (b)  ExpressVu shall use its commercially reasonable efforts to obtain the
          agreement of its existing distributors and dealers that they will not
          directly or indirectly sell Units or programming into the U.S. (and
          shall obtain the agreement of all such future distributors and dealers
          to so comply with such provisions) so as to preclude such distributors
          and dealers from, directly or indirectly, offering for sale set top
          boxes and/or programming intended for use in Canada by Subscribers to
          ExpressVu's DTH Service to Persons resident in the United States. 

18.6 THIRD PARTY SIGNAL PROTECTION PROVISIONS.

     (a)  Each of ESC and its Affiliates will use its commercially reasonable
          efforts to ensure that any agreement into which it enters, that
          contemplates the provision to a third party DTH Service provider in
          North America of technology similar to the System and the Boxes (a
          "Third Party 

<PAGE>

                                      -35-


          Agreement"), will contain provisions which are reasonably designed to
          preclude such third parties from using or authorizing the reception of
          ExpressVu's Canadian programming signals, Boxes and Outdoor Units
          intended for use by subscribers to ExpressVu's DTH Service to receive
          programming from the DTH Service of the third party (the "Protective
          Terms").  If it comes to the attention of ESC or its Affiliates (in
          which case, ESC will immediately inform ExpressVu of such), or if
          ExpressVu offers satisfactory evidence to ESC, that the Protective
          Terms of a Third Party Agreement are being violated by a third party,
          ESC or its applicable Affiliate shall take commercially reasonable
          actions permitted under such Third Party Agreement to enforce the
          Protective Terms against such third party, including, if necessary,
          the termination of such Third Party Agreement.  For the purposes of
          this Section, no violation of the Protective Terms by a third party
          shall be deemed to have occurred unless ESC or its Affiliates
          determine, or ExpressVu is able to reasonably demonstrate to ESC, that
          5000 or more Boxes and/or Outdoor Units intended for use by
          subscribers of ExpressVu's DTH Service are being used to receive
          programming from the DTH Service of the third party.  If, after a
          request from ExpressVu to enforce the Protective Terms against such
          third party, ESC or its applicable Affiliate fails within 30 days to
          (i) use its commercially reasonable efforts to cause such third party
          to commence complying with the Protective Terms or (ii) terminate such
          third party agreement, then (as the sole remedy of ExpressVu under
          this Section 18.6(a)) the EchoStar Parties' rights under Section 31.1
          of this Agreement shall immediately terminate.

     (b)  Subject to its conversion rights under Section 18.3 specifically with
          respect to subscribers to ESC's DTH Service, ExpressVu agrees to
          ensure that it does not use set top boxes and outdoor units intended
          for use by subscribers to a third party DTH Service, licenced by the
          CRTC to provide DTH Services in the Territory, to receive programming
          from ExpressVu's DTH Service, provided that, if such a third party
          ceases to provide their subscribers with DTH Services for a period of
          not less than 30 days, ExpressVu's obligations under this Section in
          respect of such third party shall terminate.

18.7 SURVIVAL OF CERTAIN TERMS.  The parties agree that the rights and
obligations of the parties under Section 18.1(c) shall survive the termination
of this Agreement, provided that the reporting and auditing obligations
contained therein shall terminate with this Agreement.

                               BREACH OF SECURITY

20.1 BREACH OF SECURITY.  HTS and ExpressVu shall use their best efforts to
protect the security of all elements of the System.  Notwithstanding any
provision to the contrary in this Agreement, if either party becomes aware of
any breach of security in respect of any aspect of the System or HTS' system
which results or may result in unauthorized third parties gaining access to one
or more channels carried by the Smart Cards (a "Breach of Security"), it shall
immediately give full written details of the breach to the other.  

20.2 REMEDY.  ExpressVu acknowledges that the primary responsibility for
remedying a Breach of Security shall be Nagra's and ExpressVu's but not HTS'
except as the Breach of Security pertains to the Boxes.  On becoming aware of a
Breach of Security that does not pertain to the Boxes, HTS and ExpressVu
together with Nagra shall evaluate the Breach of Security and jointly determine
the appropriate remedy therefor.  In the event that a similar Breach of Security
has affected the business of HTS in the United States, HTS shall, at ExpressVu's
request and at ExpressVu's cost, remedy the Breach affecting ExpressVu's System
in the same manner as HTS is remedying its own breach.  If the Breach of
Security relates in whole or in part to the Boxes, HTS shall, at HTS' cost,
promptly use its reasonable efforts to remedy the Breach of Security and if new
Boxes are required in order to do so, they shall be supplied by HTS at its cost
of such Boxes.  ExpressVu and HTS agree furnish to one another with all
reasonable assistance and information in connection with any Breach of Security.

20.3 RECOMMENDATIONS.  Throughout the term hereof, HTS shall consult with
ExpressVu and make recommendations to ExpressVu regarding the steps HTS intends
to take to remedy any Breach of Security.  HTS' obligation to remedy any Breach
of Security promptly pursuant to Section 20.2 is subject to any request by
ExpressVu, in its sole discretion, to delay the implementation of such remedy
provided that, for greater certainty, HTS shall at all times be free to remedy
any Breach of Security affecting its own system.

          hereof or at any time during the term of this Agreement (unless
          otherwise terminated pursuant to

<PAGE>

                                      -39-


          Section 21.8), which have as a primary component "Dish" or "HTS",
          including, without limitation, the trade marks and logos set forth in
          Sections A and C, respectively, of Schedule 13 attached hereto and
          (ii) such other marks and logos as may be agreed upon by the parties
          from time to time (collectively, the "Exclusive Licensed Trade
          Marks").  Subject as hereinafter provided and only to the extent that
          ESC possesses such rights, ESC hereby grants ExpressVu the
          non-exclusive and royalty-free right to use in Canada, in connection
          with ExpressVu's DTH Service, (i) all marks and logos in use by ESC,
          as of the date hereof or at any time during the term of this Agreement
          (unless otherwise terminated pursuant to Section 21.8), which have as
          a primary component "Echostar" including, without limitation, the
          trade marks and logos set forth in Section B of Schedule 13 attached
          hereto and (ii) such other marks and logos as may be agreed upon by
          the parties from time to time (collectively, the "Non-Exclusive
          Licensed Trade Marks").  ExpressVu agrees that the nature and quality
          of its use of the Licensed Trade Marks shall conform to standards set
          by and under the control of ESC.  Accordingly, ExpressVu shall consult
          with ESC with respect to any actual intended use of the Licensed Trade
          Marks and ExpressVu shall refrain from so using the Licensed Trade
          Marks if ESC objects to any such use, provided that any such objection
          must be based on reasonable grounds.  ESC hereby confirms ExpressVu
          may identify its DTH Service as "Dish Network Canada" or "Dish Network
          by ExpressVu" or to similar effect.  

     (b)  Without limiting the generality of the foregoing, ExpressVu shall not
          change the look and feel of any logos included in the Licensed Trade
          Marks but shall be permitted to use and depict them in various sizes
          and ExpressVu shall ensure that no Licensed Trade Mark is used as part
          of its corporate name or confusingly associated with such corporate
          name.  Notwithstanding anything else herein contained, ESC
          acknowledges that it shall not object to use by ExpressVu of the
          Licensed Trade Marks on the basis of an objection to the programming
          provided by ExpressVu on its DTH Service so long as such programming
          is in compliance with all applicable Canadian regulatory and legal
          requirements and so long as the Licensed Trade Marks are not
          associated directly with any adult programming.

21.2 RIGHT TO SUB-LICENSE.  Subject as hereinafter provided, ESC hereby further
grants ExpressVu the right to grant rights to use the Licensed Trade Marks to
distributors of Units in the Territory in connection with the sale by such
distributors of subscriptions to ExpressVu's DTH Service in accordance with the
sub-licensing agreement in the form attached hereto as Schedule 14.  

<PAGE>

                                      -40-


21.3 RESTRICTIONS ON ESC'S USE.  Subject as hereinafter provided, ESC will not
use or permit any Person to use the Exclusive Licensed Trade Marks in Canada in
connection with any broadcast distribution undertaking or other
telecommunications-related service, including, without limitation, a DTH
Service, cable television service, MMDS or LMCS, without ExpressVu's prior
written consent.  Notwithstanding the foregoing, ESC may (a) continue to use
such of the Exclusive Licensed Trade Marks as it is currently using in
connection with ESC's C-Band business in the Territory in such manner as it is
currently using such marks and (b) grant rights to use the Exclusive Licensed
Trade Marks (subject to the permitted business uses set out elsewhere herein) to
distributors and dealers of Units in the Territory in connection with the sale
by such distributors or dealers of subscriptions to ExpressVu's DTH Service.  

21.4 NOTIFICATIONS.  ESC and ExpressVu will promptly notify the other of any and
all third party activity which might adversely affect the Licensed Trade Marks
and which comes to their attention. 

21.5 ACTIONS BY ESC.  ESC may, in its sole discretion and at its own expense
mount any actions or proceedings against a third party for infringement of the
Licensed Trade Marks in the Territory or for any other activity in the Territory
which it deems may adversely affect the Licensed Trade Marks.  ExpressVu will,
at request of ESC, join in such actions or proceedings and, at the expense of
ESC, will provide all reasonable assistance to ESC in connection with such
actions or proceedings.  The conduct of such actions and proceedings will be at
the sole discretion of ESC.  Any costs, damages or profits awarded in such
actions or proceedings will be for the account of ESC.  

21.6 ACTIONS BY EXPRESSVU.  In the event that ESC does not mount an action or a
proceeding within 30 days of ExpressVu giving notice that it wishes an action or
proceeding to be brought against a third party, ExpressVu may, at its own
expense, bring such action or proceeding against a third party for infringement
of the Licensed Trade Marks in the Territory or any other activity which it
deems may adversely affect the Licensed Trade Marks in the Territory.  ESC will,
at ExpressVu's request, join in such action or proceeding and, at ExpressVu's
request, will provide all reasonable assistance to ExpressVu in connection with
such action or proceeding.  Any costs, damages, or profits awarded in such
action or proceeding will be for the account of ExpressVu.

21.7 PROTECTION OF LICENSED TRADE MARKS.  ESC shall take such steps as are
necessary to register and maintain the Licensed Trade Marks in Canada with the
appropriate government authorities and the maintenance of such registrations
provided that ESC shall not be required to so register or maintain any such
Licensed Trade Mark which it does not otherwise wish to register or maintain in
Canada unless ExpressVu pays all of ESC's costs and expenses in registering and
maintaining the Licensed Trade Marks which ExpressVu wishes ESC to so register
and maintain (provided further that, if ESC wishes to register and maintain any
such Licensed Trade Marks in Canada other than as pursuant

<PAGE>

                                      -41-


to an ExpressVu request, this shall be done at ESC's cost and expense). 
ExpressVu shall provide such co-operation and assistance in the protection of
the Licensed Trade Marks as ESC may reasonably request.  The parties'
obligations under this Section shall not alter or detract from the obligations
of the parties set out in Sections 21.5 and 21.6.  For greater certainty,
ExpressVu acknowledges and agrees that its license to the Licensed Trade Marks
provided hereunder and any of its actions conducted in respect of the Licensed
Trade Marks in accordance with the provisions of this Article, shall not confer
upon ExpressVu any proprietary rights or interest to any Licensed Trade Marks.

21.8 TERMINATION OF EXPRESSVU'S RIGHT TO USE THE LICENSED TRADE MARKS.  ESC may
terminate ExpressVu's rights to use the Licensed Trade Marks and all of its
other obligations under the foregoing provisions of this Article 21 if, but only
if:

     (a)  [CONFIDENTIAL MATERIAL REDACTED] 

     (b)  [CONFIDENTIAL MATERIAL REDACTED] 





     (c)  an Affiliate of ExpressVu (provided that, for greater certainty,
          neither WIC Western International Communications Ltd. nor Canadian
          Satellite Communications Inc. - nor any of their Affiliates shall be
          considered to be Affiliates of ExpressVu) provides a DTH Service
          (excluding a data distribution business, subject to the invocation of
          the provisions of Section 19.2 by the EchoStar Parties in accordance
          with the terms thereof) in the U.S. in competition to the DTH Service
          provided by ESC;

<PAGE>

                                      -42-


     (d)  if ExpressVu or any other Person to whom this Agreement is assigned by
          ExpressVu pursuant to Section 35.1 is at any time Controlled by a
          Person (or an Affiliate of any such Person) owning a Controlling
          interest in a Person providing a DTH Service (excluding a data
          distribution business, subject to the invocation of the provisions of
          Section 19.2 by the EchoStar Parties in accordance with the terms
          thereof) in the U.S. in competition to the DTH Service provided by
          ESC; or

     (e)  if this Agreement is terminated in accordance with its terms.

21.9 NOTICE OF TERMINATION.  If ESC terminates ExpressVu's rights to use the
Licensed Trade Marks pursuant to Section 21.8, ExpressVu shall nevertheless
continue to have non-exclusive rights with respect to the Licensed Trade Marks
provided for in Sections 21.1 through 21.7, inclusive, until one year after the
date it receives written notice from ESC of such termination, provided that if
at any time after receipt of such written notice of termination ExpressVu begins
using another brand name in association with its DTH Service, it shall cease to
have such rights 90 days after it first begins to use such other brand name.  

21.10     EFFECT OF TERMINATION.  Notwithstanding any termination of ExpressVu's
rights to use the Licensed Trade Marks pursuant to Section 21.8, any Units sold
to Subscribers which bear the Licensed Trade Marks prior to the date such
termination becomes effective shall continue to be permitted to be used by
Subscribers and any Units or other inventory bearing the Licensed Trade Marks on
hand on the date such termination becomes effective may be used by ExpressVu in
the normal course of business after such effective date of termination. 
Furthermore, ExpressVu shall be required to purchase from HTS all Outdoor Units,
Smart Cards, LNBs and other parts held in stock by HTS as contemplated by
Section 14.9 on the effective date of such termination at a price equal to HTS'
cost thereof.  

21.11     INDEMNITY FOR COSTS OF CERTAIN CLAIMS.

     (a)  ExpressVu shall indemnify and hold the EchoStar Parties harmless from
          and against all legal costs and expenses, subject to the limitations
          set out below, which the EchoStar Parties may suffer or incur arising
          out of or resulting from any claim or action against the EchoStar
          Parties by a third party where the naming of the EchoStar Parties by a
          third party in such claim or action arises from the association of the
          EchoStar Parties with ExpressVu as a result of the use by ExpressVu of
          the Licensed Trade Marks.  Any indemnity claim made by the EchoStar
          Parties under this Section shall be limited to a maximum of
          U.S.$25,000.  Nothing in this Section shall be construed as providing
          an indemnity to the EchoStar Parties from ExpressVu in those instances
          where the EchoStar Parties are 


<PAGE>

                                     -43-

          actually found to be properly named in an action or claim by a third
          party or as providing for an indemnity for the payment of any damages
          found payable by the EchoStar Parties as a result of such a claim or
          action and nothing in this Section shall be construed as detracting
          from or limiting in any manner other indemnity rights provided
          elsewhere in this Agreement.

     (b)  The EchoStar Parties shall indemnify and hold ExpressVu harmless from
          and against all legal costs and expenses, subject to the limitations
          set out below, which ExpressVu may suffer or incur arising out of or
          resulting from any claim or action against ExpressVu by a third party
          where the naming of ExpressVu by a third party in such claim or action
          arises from the association of ExpressVu with the EchoStar Parties as
          a result of the use by ExpressVu of the Licensed Trade Marks.  Any
          indemnity claim made by ExpressVu under this Section shall be limited
          to a maximum of U.S.$25,000.  Nothing in this Section shall be
          construed as providing an indemnity to ExpressVu from the EchoStar
          Parties in those instances where ExpressVu is actually found to be
          properly named in an action or claim by a third party or as providing
          for an indemnity for the payment of any damages found payable by
          ExpressVu as a result of such a claim or action and nothing in this
          Section shall be construed as detracting from or limiting in any
          manner other indemnity rights provided elsewhere in this Agreement.

          (ii) do not (or would not with the giving of notice, the lapse of time
               or the happening of any other event or condition) result in a
               violation or a breach of, or a default under or give rise to a
               right of termination, amendment or cancellation or the
               acceleration of any obligation under (1) any charter or by-law
               instruments of either of the EchoStar Parties; (2) any material

               efforts to obtain as soon as possible;

     (c)  each of the EchoStar Parties is in compliance with (i) all applicable
          statutes, laws, regulations, orders, judgements, injunctions or
          rulings of any government or governmental agency and (ii) all

          effect on the System or the Software or the ability of the EchoStar
          Parties to perform their obligations hereunder;

     (d)  except as set forth in Schedule 18 attached hereto, to the best of the
          EchoStar Parties' knowledge, there is no action, suit or proceeding at
          law or in equity, by any person, nor any arbitration, administrative
          or other proceeding by or before any governmental entity, pending or
          threatened, against the EchoStar Parties or any of their Affiliates
          relating to the use of the System or the Software by the EchoStar
          Parties;

     (e)  subject to this Agreement becoming effective on the Effective Date and

          Hardware provided herein or, in the case of Software, the right to
          license or sub-license the same to ExpressVu as contemplated herein;

     (f)  HTS has used or will use its commercially reasonable efforts to obtain
          all necessary rights and approvals to assign to ExpressVu the benefit
          of any manufacturers' warranties relating to any component of the
          System, where the underlying product has a cost in excess of
          U.S.$20,000.00;

     (g)  to the best of their knowledge, the Specifications, whether in
          original form or as amended by the EchoStar Parties (not requested by
          ExpressVu) to incorporate the customization modifications, will be
          prepared in such a way that if the System is implemented in the
          Territory in accordance with the Specifications, then the System will
          be capable of operating and functioning as a multiple channel, direct-
          to-home, transmission system which accords with the MPEG 2 DVB
          standard and which will be capable of providing satellite-delivered
          audio, video and/or data services available to in excess of 500,000
          Subscribers with access to in excess of 100 channels in the Territory
          (assuming ExpressVu has available to it adequate satellite carriage
          and transmitting capacity and subject to ExpressVu purchasing and
          installing sufficient incremental Hardware and Software to permit the
          theoretical System capacity of 100 channels to be realized);

     (h)  to the best of their knowledge, the System and/or any components
          thereof, will comply with and provide, in all material respects, the
          performance levels, functions, capabilities and standards specified in
          the Specifications;

     (i)  neither of the EchoStar Parties nor any of their Affiliates have
          entered into and, until the Acceptance Certificate for the System has
          been issued, they will not enter into, any contract with any customer
          for an undertaking similar to the systems integration obligations
          undertaken hereunder, the liquidated damages provisions of which are
          more onerous than the liquidated damages provisions contained herein; 

     (j)  ESC has been granted full right, power and authority by EchoStar
          Communications Corporation and each of its Affiliates which has rights
          to the Licensed Trade Marks to grant ExpressVu the rights granted to
          it pursuant to Article 21; 

     (k)  it is not necessary that any other Affiliates of EchoStar
          Communications Corporation be a party to this Agreement in order for
          ExpressVu to acquire the rights it is intended ExpressVu will acquire
          pursuant to this Agreement; and



<PAGE>

                                     -46-

     (l)  the terms and conditions of the Dominion Agreement as at the date
          hereof directly and indirectly provide certain protections to the
          competitive market position of the EchoStar Parties which protections
          effectively place ExpressVu in a competitive position which is not
          worse than that of the EchoStar Parties with regard to the permitted
          activities of Dominion Video Satellite Inc. under the Dominion
          Agreement.

22.2 REPRESENTATIONS AND WARRANTIES BY EXPRESSVU.  ExpressVu represents and

               corporate action on the part of ExpressVu; and

          (ii) do not (or would not with the giving of notice, the lapse of time
               or the happening of any other event or condition) result in a
               violation or a breach of, or a default under or give rise to a
               right of termination, amendment or cancellation or the
               acceleration of any obligation under (i) any charter or by-law

               or consent from, any governmental authority pursuant to any
               applicable law or any other Person pursuant to any contract or
               instrument by which ExpressVu is bound; 


<PAGE>

                                     -47-

     (c)  ExpressVu is not bound by the provisions of any other Agreement with
          any third party which would prevent ExpressVu from entering into and
          performing this Agreement; 

     (d)  subject as noted in Section 22.2(b)(iii) with respect to the need to
          obtain approval of the CRTC of certain changes in the ownership of its

          necessary Canadian governmental authorities required to operate a DTH

                        [CONFIDENTIAL MATERIAL REDACTED] 






22.3 SURVIVE AGREEMENT.  Except as otherwise expressly provided therein, the
representations and warranties of the parties contained in Sections 22.1 and
21.2 are made as of the date of this Agreement and shall not be deemed to have
been made as at subsequent date.  Except as otherwise expressly provided in this
Agreement, the covenants, representations and warranties of the parties
contained in this Agreement shall not merge on, and shall survive the date
hereof, and, notwithstanding the execution and delivery of this Agreement, or
any investigation made by or on behalf of any party hereto, shall continue in
full force and effect.  The execution of this Agreement shall not prejudice any
right of any party against the other parties in respect of anything done or
omitted hereunder or in respect of any right to damages or other remedies.

the DVB scrambler and data encryptor and the interfaces developed by HTS in
collaboration with the supplier of the compression equipment between the
Conditional Access System and the compression equipment.  Where HTS is co-owner
or licensee of these Intellectual Property Rights with or from the supplier of
the underlying technology, it warrants, represents and undertakes that it is and
shall remain entitled to grant the rights granted hereunder except where
ExpressVu has obtained such rights directly with the owner of such rights.  

24.2 IMPROVEMENTS.  HTS and ExpressVu shall consult and co-operate with each
other from time to time as may be reasonably necessary with respect to
Improvements.  Each of such parties shall inform the other party in a timely
manner of any significant Improvements developed or acquired by such party and,
at the request of the other party, disclose the details thereof to the other
party, except insofar as such disclosure would disclose information which is
subject to confidentiality obligations in favour of a third party, which in the
case of HTS would include, without limitation, a specific development performed
by HTS for another customer. 

24.3 RIGHTS VESTING.  With respect to rights (including all Intellectual
Property Rights) to all Improvements made or developed either by HTS or
ExpressVu, it is agreed that:

                                      -49-


     (a)  in the case of Improvements developed solely by ExpressVu, such
          Improvements shall belong exclusively to HTS; provided, however, that
          ExpressVu shall be entitled to a limited, non-transferable, royalty-
          free right to use the Improvements in connection with ExpressVu's DTH
          Service in the Territory during the term of this Agreement;

     (b)  in the case of Improvements made or developed by HTS specifically at
          ExpressVu's request, which enable the Software to perform functions
          differently or to perform new functions: (i) such Improvements will be
          charged for by HTS at Standard Rates; and (ii) such Improvements shall
          belong exclusively to HTS; provided, however, that ExpressVu shall be
          entitled to a limited, non-transferable, royalty-free right to use the
          Improvements in connection with ExpressVu's DTH Service in the
          Territory during the term of this Agreement; and 

     (c)  in the case of Improvements other than those referred to in Sections
          24.3(a) and 24.3(b), if ExpressVu wishes to use such Improvements, it
          shall be entitled to do so against payment to HTS of such royalties
          and fees as HTS may reasonably determine from time to time. 

24.4 REGISTRATION.  HTS and ExpressVu undertake to co-operate with one another,
in the utmost good faith, in order to arrange or obtain registration of
Intellectual Property Rights in Improvements, and to this end they shall execute
and arrange for the signature of all documents and forms in pursuance of any
application for registration of Intellectual Property Rights in the
Improvements.

24.5 USE.  ExpressVu shall not, otherwise than as specifically permitted by the
terms of this Agreement, use, disclose, apply, sell or in any way turn to
account, whether directly or indirectly, the Intellectual Property Rights. 

24.6 OBLIGATION.  ExpressVu shall:

     (a)  not, other than as permitted by this Agreement, copy or reproduce or
          translate the Software and shall not communicate, whether
          electronically or otherwise, the Software to any third party, without
          the prior written consent of HTS which may be withheld by HTS in its
          absolute discretion; 

     (b)  supervise and control the use of the Software to ensure that it takes
          place in accordance with the terms of this Agreement;

     (c)  reproduce and include HTS' copyright notices on all copies, including
          screen-based displays, of the Documentation and of the Software made
          by ExpressVu in accordance with the terms of this Agreement; 

<PAGE>

                                      -50-


     (d)  during this Agreement and thereafter, maintain the confidentiality of
          the Documentation and the Software and not make it available, either
          partly or completely, to any Person other than those employees,
          consultants and advisors who will not be able to fulfil their duties
          without access thereto; or

     (e)  ensure that there shall at all times during the term of this Agreement
          be in existence currently binding confidentiality undertakings given
          by each such employee, consultant or advisor in favour of ExpressVu,
          and ExpressVu shall be responsible for any breach of such undertaking
          committed by any such employee, consultant or advisor and, at HTS'
          request, will use its reasonable commercial efforts to enforce any
          such undertaking.  

24.7 RESTRICTIONS ON USE.  All copies of the Software made by ExpressVu,
including computer programs and Documentation, shall be subject to the same
restrictions on use and disclosure as are contained in this Agreement with
respect to the original program copies and Documentation supplied by HTS.

24.8 DOCUMENTATION.  ExpressVu specifically acknowledges and agrees that the
Documentation whether prepared by or on behalf of HTS or not, for the purpose of
implementing the System, falls within the scope of this Agreement and that all
rights in and to the Documentation, including the right of ownership of the
Documentation, vests in HTS.  

24.9 THIRD PARTY INTELLECTUAL PROPERTY CLAIMS.  

     (a)  Except with respect to the persons, entities and technology listed on
          Schedule 19 attached hereto, as to which the indemnification and other
          obligations of HTS set forth in this Section 24.9 shall not apply, HTS
          shall indemnify and hold harmless ExpressVu from and against all
          losses, damages, costs and expenses (including, without limitation,
          reasonable legal costs and expenses) which ExpressVu may suffer or
          incur arising out of or resulting from any claim or action against
          ExpressVu by a third party alleging that (i) the use by ExpressVu of
          the HTS Software or (ii) the sale of the Boxes in Canada or (iii) any
          Software or other Intellectual Property Rights (excluding Intellectual
          Property Rights associated with the Hardware) incorporated into the
          System by HTS and which is not listed in Schedule 6 attached hereto,
          infringes any Intellectual Property Right of such third party. 
          Nothing herein shall be construed as or deemed an admission by HTS of
          any ownership or other rights of the Persons or entities listed on
          Schedule 19 attached hereto with respect to any technology.  
          Notwithstanding the foregoing, in respect of the Persons and
          technology listed on Schedule 19, HTS and its applicable Affiliates
          agree to

<PAGE>

                                      -51-


          use their commercially reasonable efforts to obtain for ExpressVu the
          benefit of any settlement, at ExpressVu's expense, entered into with
          such Persons or in respect of such technology for the dismissal or
          withdrawal of claims or actions brought against HTS or its applicable
          Affiliates by such Persons or in respect of such technology.

     (b)  If ExpressVu intends to make a claim for indemnity against HTS as
          contemplated by Section 24.9(a), ExpressVu shall as soon as is
          reasonably possible notify HTS in writing of such claim, which notice
          shall specify, in reasonable detail, the nature and estimated amount
          of the claim.  HTS shall have 30 days after receipt of such notice to
          undertake, conduct and control, through counsel of its own choosing
          and at its expense, the settlement or defence thereof, and ExpressVu
          shall cooperate with HTS in connection therewith provided that with
          respect to settlements entered into by HTS (i) the consent of
          ExpressVu shall be required if the settlement provides for equitable
          relief against ExpressVu, which consent shall not be unreasonably
          withheld or delayed; and (ii) HTS shall obtain the release of
          ExpressVu from any further liability relating to such claim.  If HTS
          undertakes, conducts and controls the settlement or defence of such
          claim (i) HTS shall permit ExpressVu to participate in such settlement
          or defence through counsel chosen by ExpressVu, provided that the fees
          and expenses of such counsel and any other costs which would not have
          been incurred by ExpressVu had it not elected to participate in such
          settlement or defence shall be borne by ExpressVu; and (ii) HTS shall
          promptly reimburse ExpressVu for the full amount of any loss resulting
          from any claim and all related expenses (other than the fees and
          expenses of counsel as aforesaid) incurred by ExpressVu.  ExpressVu
          shall not pay or settle any claim so long as HTS is reasonably
          contesting any such claim in good faith on a timely basis. 
          Notwithstanding the foregoing, ExpressVu shall have the right to pay
          or settle any such claim, provided that in such event it shall waive
          any right to indemnity therefor by HTS and no such payment or
          settlement shall constitute any agreement of HTS to take or refrain
          from taking any action or create any liability or obligation on the
          part of HTS except with the prior written consent of HTS.    

     (c)  If HTS does not notify ExpressVu within 30 days after the receipt of
          ExpressVu's notice of a claim of indemnity under Section 24.9(a) that
          it elects to undertake the defence thereof, ExpressVu shall have the
          right, but not the obligation, to contest, settle or compromise the
          claim in the exercise of its reasonable judgment at the expense of HTS
          on reasonable prior notice to HTS.  

<PAGE>

                                      -52-


     (d)  In the event of any claim by a third party against ExpressVu, the
          defence of which is being undertaken and controlled by HTS, ExpressVu
          will use all reasonable efforts to make available to HTS those
          employees whose assistance, testimony or presence is necessary to
          assist HTS in evaluating and in defending any such claims; provided
          that HTS shall be responsible for the expense associated with any
          employees made available by ExpressVu to HTS, which expense shall be
          equal to an amount to be mutually agreed upon per person per hour or
          per day or each day or portion thereof that such employees are
          assisting HTS and which expenses shall not exceed the actual cost to
          ExpressVu associated with such employees.

     (e)  ExpressVu shall make available to HTS or its representatives on a
          timely basis all documents, records and other materials in its
          possession, at the expense of HTS, reasonably required by HTS for its
          use in defending any claim and shall otherwise cooperate on a timely
          basis with HTS in the defence of such claim. 

24.10  INFRINGEMENT OF INTELLECTUAL PROPERTY RIGHTS.  Except for the 
potential claims listed in Schedule 19 attached hereto, HTS represents and 
warrants to ExpressVu that as at the date of this Agreement it is not aware 
of any claim by any third party that (i) the use by ExpressVu of the HTS 
Software or (ii) the sale of the Boxes in Canada or (iii) any Software or 
other Intellectual Property Rights (excluding Intellectual Property Rights 
associated with Hardware) incorporated into the System by HTS and which is 
not listed in Schedule 6 attached hereto, infringes or would infringe, as 
applicable, any Intellectual Property Right belonging to a Third Party.

24.11  INJUNCTION.  

       (a) If any Hardware or Software manufactured or supplied by HTS to
           ExpressVu to which the indemnity of HTS contained in Section 24.9
           applies is held to infringe any valid letters of patent, copyright,
           mask work, trademark, trade secret or any other Intellectual Property
           Rights of any third party and ExpressVu is enjoined from using the
           same, or if HTS believes such infringement is likely, HTS shall do 
           one or more of the following: 

           (i) exert all reasonable efforts at its option and expense to procure
               for ExpressVu the right to use such Hardware or Software free of
               any liability for such infringement; or

<PAGE>

                                      -53-


           (ii)  modify such Hardware or Software so that it becomes non-
                 infringing while remaining in compliance with the 
                 Specifications in all material respects; or

           (iii) replace such Hardware or Software with a non-infringing item
                 while remaining in compliance with the Specifications in all
                 material respects.

     (b)  If the infringement is alleged prior to completion of delivery of the
          Hardware, HTS has the right to decline to make further shipments
          without being in breach of contract in which case HTS will refund to
          ExpressVu any payments on account of the Purchase Price which it has
          made prior thereto.

24.12  LIMITATION OF ECHOSTAR'S INDEMNITY.  EchoStar's indemnity in this
Article shall not extend to any infringement to the extent it arises from any
design or instruction in writing supplied by ExpressVu or where ExpressVu uses,
modifies or sells the Hardware or Software in a combination other than that
recommended by EchoStar.

24.13  HTS' ENTIRE OBLIGATION.  This Article states the entire obligation and
liability of HTS, and the sole remedy of ExpressVu, in respect of any
infringement or alleged infringement of any Intellectual Property Rights.

27.2 EXCEPTIONS.  EchoStar shall not be required to make payment of liquidated
damages pursuant to Section 27.1 if the reason it fails to attain System
Completion as therein provided is due to:

     (a)  the Hardware being detained at customs or failure of suppliers to make
          timely delivery thereof (except where caused by the negligence of
          EchoStar, including failure to place orders in a timely manner); 

     (b)  ExpressVu's failure to timely perform its obligations hereunder; 

     (c)  the negligence, gross negligence or wilful misconduct of ExpressVu; 
          or 

     (d)  Customer Modifications or the choice by ExpressVu of SMS Software
          other than that provided by CSG.

27.3 WAIVER OF DAMAGES.  The parties hereby agree that ExpressVu, in its sole
discretion, may waive any amount arising as liquidated damages as a consequence
of HTS failing to attain System Completion in a timely manner as aforesaid.

                                   TERMINATION

28.1 TERMINATION OF AGREEMENT.  This Agreement may be terminated: 

     (a)  forthwith by the EchoStar Parties in the event that, except as
          permitted by the Source Code Escrow Agreement, ExpressVu (i) adapts,
          reverse engineers or decompiles the whole or any part of the
          Conditional Access System or any other Intellectual Property Rights of
          HTS; or (ii) causes any other Person to do so, without, in either
          case, HTS' prior written consent which may be withheld at its sole
          discretion; 

     (b)  forthwith by ExpressVu or the EchoStar Parties, as the case may be, if
          the other of them (the "defaulting party", which term means, for
          greater certainty, in the case of termination by ExpressVu, either of
          the EchoStar Parties) has made or attempted to make any assignment for
          the benefit of its creditors or if any action or proceedings under any
          bankruptcy or insolvency laws are taken by or against it, or if the
          defaulting party has effected a compulsory or voluntary liquidation,
          (and has not been discharged within 90 days), or if any event
          analogous to any of the foregoing under the law of any jurisdiction
          has occurred in respect of the defaulting party; 

     (c)  forthwith by ExpressVu or the EchoStar Parties, as the case may be,
          (the "notifying party") if the other of them (the "defaulting party",
          which term means, for greater certainty, in the case of termination by
          ExpressVu, either of the EchoStar Parties) commits a material breach
          or is in material default of any of its obligations under this
          Agreement which has not been cured within 30 days after the notifying
          party gives written notice to the defaulting party of such breach or
          default unless the defaulting party is using and continues to use its
          best efforts to remedy such breach or default and no material
          prejudice to the interests of the notifying party has occurred as a
          result of such breach or default; 

     (d)  upon not less than 30 days written notice by ExpressVu or the EchoStar
          Parties, as the case may be, (the "notifying party") if the other of
          them (the "Force Majeure Party", which term means, for greater
          certainty, in the case of termination by ExpressVu, either of the
          EchoStar Parties) has invoked Force Majeure to excuse it from
          performance of any material obligation hereunder and such Force
          Majeure continues in effect for more than 60 days; 

<PAGE>

                                      -57-


     (e)  by ExpressVu in the event that an Acceptance Certificate is not issued
          in respect of the System Completion within 120 days of the date such
          System Completion is required to be achieved as stated in the GANTT
          Chart, provided that, for greater certainty, ExpressVu shall have no
          right to terminate this Agreement if the reason the Acceptance
          Certificate has not been issued is due to the fault of ExpressVu; 

     (f)  by the EchoStar Parties in the event that ExpressVu has not paid any
          portion of the Purchase Price within 60 days of the due date
          hereunder; 


                        [CONFIDENTIAL MATERIAL REDACTED] 








     (j)  by ExpressVu on the later to occur of the following:

          (i)  the end of the useful life of the first DBS satellite on which
               ExpressVu acquires the right to use transponders to provide its
               DTH Service, provided that if ExpressVu does not obtain such
               right by the 10th anniversary of the date of this Agreement,
               ExpressVu may exercise its right under this Section 28.1(j) on or
               after the 10th anniversary of this Agreement; or

          (ii) on or after the 10th anniversary of the date of this Agreement;

     (l)  by either the EchoStar Parties or ExpressVu pursuant to Section 32.4. 

28.2 SURVIVAL.  Any termination of this Agreement pursuant to Section 28.1 shall
be without prejudice to any other rights or remedies to which a party may be
entitled hereunder or at law and shall not affect any accrued rights or
liabilities of either party or the coming into or continuance in force of any
provision hereof which is expressly or by implication intended to come into or
continue in force on or after such termination.

28.3 OBLIGATIONS ON TERMINATION OF AGREEMENT.  In the event that this Agreement
is terminated by either party pursuant to Section 28.1, all rights and
obligations of the parties hereunder shall cease (except as otherwise provided
herein), including, but not limited to, the following:
     
     (a)  ExpressVu shall cease to use any part of HTS' Intellectual Property

          the provisions of the Source Code Deposit Agreement; 

     (b)  ExpressVu shall return to HTS all copies of the HTS Software, subject

     (c)  ExpressVu shall satisfy all amounts owing to HTS pursuant to Section
          14.9 and in respect of Smart Cards, CA Components and/or Boxes ordered
          by ExpressVu or its designee(s) for which HTS has not been paid as at
          the date of termination of the Agreement;

     (d)  ExpressVu's rights to use of the Licensed Trade Marks will terminate,
          subject to provisions of Sections 21.9 and 21.10; and

     (e)  the EchoStar Parties' obligations under Section 4.2 and Articles 11
          and 12 terminate.

     (b)  all substitutions and replacements of and increases, additions and
          accessions to the Hardware; and

     (c)  all proceeds in any form derived directly or indirectly from any
          dealing with all or any part of the Hardware and all or any part of
          the substitutions and replacements thereof and increases, additions
          and accessions thereto or the proceeds therefrom, including, without
          limitation, any payment representing indemnity or compensation for all
          or any part of the Hardware, or all or any part of the substitutions
          and replacements thereof and increases, additions and accessions
          thereto, lost, damaged, destroyed, expropriated or taken.

29.2 SECURE PAYMENT.  The charges, pledges, transfers, assignments and security
interest granted hereby secure the payment by ExpressVu to HTS of the Purchase
Price.  ExpressVu shall from time to time, at the request of HTS, execute and

to record, register or evidence, the charges, pledges, transfers, assignments

ExpressVu or by a guarantor of its obligation to pay the same.  In furtherance
of the discharge of the security interest, HTS shall at such time deliver to
ExpressVu such releases and discharges as ExpressVu may reasonably require.

                                 CONFIDENTIALITY

34.1 CONFIDENTIALITY REGARDING TERMS AND EXISTENCE OF AGREEMENT; CONFIDENTIAL
     INFORMATION.

     (a)  Neither ExpressVu nor the EchoStar Parties will issue any press
          release or make any other public announcement regarding this Agreement
          or the transactions contemplated hereby without the consent of the
          other of them.  Each party will hold, and will cause its employees,
          consultants, advisors, agents and Affiliates to hold, in confidence,
          the terms of this Agreement, except to the extent the terms of this
          Agreement are or become a matter of public record.

     (b)  Each of the EchoStar Parties and ExpressVu agrees to hold all
          Confidential Information received by it from the other of them
          pursuant to this Agreement in confidence.

     (c)  A party receiving Confidential Information shall use such information
          only for the purpose of fulfilling its obligations under this
          Agreement.  Each document containing Confidential Information which is
          circulated to employees, Affiliates or agents of a party receiving
          such information shall bear a legend to the effect that the
          information contained therein is confidential to the disclosing party
          and that such information shall not be disclosed to other Persons.

     (d)  Upon expiration or termination of this Agreement, or at any other
          time, all Confidential Information in the possession of a party shall,
          if requested in writing by the party that disclosed such information,
          be either returned to the disclosing party or, at the receiving
          party's option, destroyed.  In all events, the receiving party may
          retain a single copy of all Confidential Information, as an archive
          record of the contents thereof, accessed solely in the event of a
          dispute between the parties concerning such contents.

     (e)  The confidentiality and non-disclosure obligations set forth in this
          Article 34 shall become effective with respect to any item of
          Confidential Information immediately upon disclosure to the receiving
          party and shall continue during the term of the Agreement and for a
          period of three years thereafter.

     (f)  Notwithstanding the other provisions of this Article 34, a party may
          disclose the terms and existence of this Agreement and Confidential
          Information to the extent required by any legal requirement (including
          
<PAGE>
                                     -65-

          disclosure requirements under federal, provincial and state securities
          laws) or by any governmental authority, but the party proposing to
          disclose such information will first notify and consult with the other
          party concerning the proposed disclosure, to the extent reasonably
          feasible.  Each party also may disclose the terms and existence of
          this Agreement and Confidential Information to its employees,
          consultants, advisors, agents, Affiliates and actual or potential
          lenders whose knowledge is necessary to facilitate the consummation of
          the transactions contemplated by this Agreement; provided that such
          Persons will be required to observe the terms of this Article 34. 
          Each party's obligation to hold information in confidence will be
          satisfied if it exercises the same care with respect to such
          information as it would exercise to preserve the confidentiality of
          its own similar information.

     (g)  For the purposes of Article 34, "Confidential Information" means all
          proprietary or confidential information disclosed by the EchoStar
          Parties or ExpressVu to the other of them in connection with this
          Agreement; provided that such information shall satisfy the following
          criteria in order to constitute "Confidential Information":  (a) if
          disclosed in written or other tangible format, such information shall
          be accompanied by reasonably prominent "Confidential" or similar
          legends; or (b) if disclosed orally or by way of observation, such
          information shall be described by the disclosing party as Confidential
          Information at the time of disclosure.  Notwithstanding the foregoing,
          the term "Confidential Information" shall not include any information
          which:  (i) was previously known to the party receiving such
          Confidential Information if such party can prove such prior knowledge
          by BONA FIDE documentation dated prior to the time of disclosure by
          the disclosing party and the receiving party did not learn such
          information from a person whom the receiving party knew was under a
          duty to the disclosing party not to disclose the information; or (ii)
          is or becomes part of the public domain; or (iii) the receiving party
          receives from an independent third party whom the receiving party
          knows is under no obligation to the disclosing party not to disclose
          it; or (iv) is independently developed by the receiving party as
          evidenced by documentation dated prior to the time of disclosure by
          the disclosing party.

                                  MISCELLANEOUS

35.1 ASSIGNMENT.  

     (a)  ExpressVu may assign its right, title and interest in this Agreement
          to (i) an Affiliate of ExpressVu, provided that ExpressVu guarantees
          performance by the assignee of ExpressVu's obligations under this
          Agreement, (ii) Telesat Canada, provided that ExpressVu guarantees
          performance by Telesat Canada of ExpressVu's obligations under this
          Agreement or (iii) any partnership or other entity into which
          ExpressVu is reorganized pursuant to Article 30 but may not otherwise
          assign or transfer any rights or obligations acquired under this
          Agreement except with the consent of EchoStar, such consent not to be
          unreasonably withheld.  Notwithstanding the foregoing, ExpressVu shall
          not be entitled to assign its right, title and interest in this
          Agreement to any Person prior to payment in full of the Purchase Price
          unless each of the shareholders of ExpressVu confirms in writing to
          EchoStar that its guarantee provided pursuant to Section 32.2(b)
          remains in full force and effect regardless of such assignment. 

     (b)  Each of the EchoStar Parties may assign their right, title and
          interest in this Agreement to an Affiliate of EchoStar, provided that
          EchoStar guarantees performance by the assignee of the EchoStar
          Parties' obligations under this Agreement, but may not otherwise
          assign or transfer any rights or obligations acquired under this
          Agreement except with the consent of ExpressVu, such consent not to be
          unreasonably withheld.  Notwithstanding the foregoing, the EchoStar
          Parties shall not be entitled to assign their right, title and
          interest in this Agreement to any Person at any time unless EchoStar
          Communications Corporation confirms in writing to ExpressVu that its
          guarantee provided pursuant to Section 32.1(b) remains in full force
          and effect regardless of such assignment. 

35.2 NO PARTNERSHIP.  Nothing in this Agreement shall be deemed to create any
joint venture, partnership or principal and agent relationship between the
EchoStar Parties and ExpressVu and none of them shall hold itself out in its
advertising or otherwise in any manner which would indicate or imply any such
relationship with the other.
  
35.3 FORCE MAJEURE.

     (a)  If by reason of Force Majeure, the EchoStar Parties or ExpressVu is
          unable, wholly or in part, to perform or comply with their respective
          obligations hereunder, then all parties shall be relieved of liability
          and shall

<PAGE>
                                     -67-

          suffer no prejudice for failing to perform or comply during the
          continuance and to the extent of the inability so caused from and
          after the happening of the event of Force Majeure provided that the
          party invoking Force Majeure gives to the other party prompt notice,
          written or oral (but if oral, promptly confirmed in writing) of such
          inability and reasonably full particulars of the cause thereof.  If
          notice is not promptly given then the parties shall only be relieved
          from such performance or compliance from and after the giving of such
          notice.  The party invoking Force Majeure shall use all reasonable
          efforts to remedy the situation and remove, so far as possible and
          with reasonable dispatch, the cause of its inability to perform or
          comply, provided, however, that settlement of strikes, lockouts and
          other industrial disturbances shall be wholly within the discretion of
          the party involved.  The party invoking Force Majeure shall give
          prompt notice of the cessation thereof.  For greater certainty, if a
          party invokes Force Majeure to excuse it from performance of an
          obligation hereunder, the other party shall be relieved of its
          obligation to make any payment to the party invoking Force Majeure on
          account of such obligation which is not being performed.  

     (b)  The term "Force Majeure" shall mean any cause of any kind whatsoever
          not within the control of a party and which such party could not, by
          reasonable diligence, have foreseen or avoided which may include
          without limitation by the following enumeration, acts of God and the
          public enemy; the elements; fire, accidents; breakdowns; vandalism;
          sabotage; breakage or accident to equipment; satellite or equipment
          failure; the necessity of making repairs to equipment, strikes,
          lockouts and any other industrial, civil or public disturbances; any
          laws, orders, rules, regulations, acts or restraints of any government
          or governmental body or authority, civil or military, including the
          orders and judgment of courts; provided, however, that the term "Force
          Majeure" shall not include the revocation or modification of any
          necessary governmental consent, authorization or approval caused by a
          violation of the terms thereof or consented to by the party holding
          such consent, authorization or approval.

35.4 VALIDITY.  If any provision of this Agreement is found or held to be
invalid or unenforceable, the validity of all the other provisions hereof shall
not be affected thereby and the parties agree to meet and review the matter and
if any valid and enforceable means is reasonably available to achieve the same
commercial objective as the invalid or unenforceable provision, the parties
shall adopt such means by way of variation of this Agreement.

35.5 SEVERABILITY.  In the event that any of the terms of this Agreement are
found to be invalid, unlawful or unenforceable, such terms (provided that they
are not fundamental to


<PAGE>
                                      -68- 

the Agreement) shall be severable from the remaining terms, which shall continue
to be valid and enforceable.

35.6 VARIATION.  No variation of or addition to this Agreement shall be of any
force or effect unless reduced to writing and signed by or on behalf of all
parties and such writing expressly states that it amends this Agreement.

35.7 ENTIRE AGREEMENT.  Except for any agreements or other instruments executed
by the parties contemporaneously herewith, this Agreement replaces all prior
agreements and arrangements between the parties and constitutes the entire
understanding between the parties relating to the subject matter of this
Agreement and no oral representations, warranties or promises shall be implied
as terms of this Agreement unless expressly incorporated herein.  In particular,
there are no conditions, warranties, or other terms, express or implied,
including as to merchantable quality, fitness for a particular purpose or any
other kind whatsoever, that are binding on HTS concerning the Hardware or Units
except as specifically stated in this Agreement.  Any condition, warranty or
other term concerning the Hardware which might otherwise be implied into or
incorporated within this Agreement, whether by statute, common law or otherwise,
is hereby expressly excluded.

35.8 WAIVER.  A waiver by any party of a breach of any term or condition of this
Agreement in any one instance shall be in writing and shall not be deemed as a
continuing waiver or a waiver of any other or subsequent breach unless such
writing so provides.

35.12 TAXES.  

      (a)  Any and all payments required under this Agreement to be made by a
           party hereto (the "Paying Party") to another party hereto (the
           "Receiving Party") shall be made free and clear of and without
           deduction or withholding for any and all present or future taxes,
           levies, imposts, deductions, charges or withholdings, and all
           liabilities with respect thereto (all such taxes, levies, imposts,
           deductions, charges, withholdings and liabilities being hereinafter
           referred to as "Taxes") unless such Taxes are required by law or the
           administration thereof to be deducted or withheld.  If the Paying
           Party shall be required by law or administration thereof to deduct or
           withhold any Taxes from or in respect of any sum payable hereunder,
           (i) subject as hereinafter provided, the sum payable shall be
           increased as may be necessary so that after making all required
           deductions or withholdings (including deductions or withholdings
           applicable to additional amounts paid under this Section 35.12) the
           Receiving Party receives an amount equal to the sum it would have
           received if no such deduction or withholding had been made, (ii) the
           Paying Party shall make such deductions or withholdings; and (iii) 
           the Paying Party shall forthwith pay the full amount deducted or 
           withheld to the relevant taxation or other authority in accordance
           with applicable law.  Within 30 days after the date of any payment of
           Taxes, the Paying Party will furnish to the Receiving Party the
           original or a certified copy of a receipt evidencing payment thereof.
           Notwithstanding the foregoing, if the reason any such Taxes are
           required to be deducted or withheld is due to the Receiving Party
           having failed to use its commercially reasonable efforts to obtain 
           the waiver referred to in Section 35.12(c), the Paying Party shall 
           have no obligation under the foregoing clause (i) to increase the sum
           payable to the Receiving Party, provided that no such failure will be
           deemed to have occurred unless the parties agree as such or unless, 
           after the submission of any such dispute to binding arbitration, the
           arbitration determines that a failure has occurred, in which 
           instance, amounts paid by the Paying Party will be reimbursed by the
           Receiving Party with interest calculated in accordance with Section 
           35.13.  

      (b)  If following the payment by a Paying Party of any Tax required to be
           deducted or withheld pursuant to Section 35.12(a), the Receiving 
           Party determines acting in good faith that it has obtained a refund 
           of taxes otherwise payable by it or obtained or used a credit or any
           other relief against other taxes on its profit or income (any of the
           foregoing being hereinafter referred to as a "Tax Credit") which the
           Receiving Party is able to quantify and identify as attributable to
           the Taxes paid by the Paying Party, then, if the Receiving Party can
           do so without any adverse

<PAGE>
                                      -71- 

           consequences for itself, the Receiving Party shall reimburse the
           Paying Party such proportion of the Tax Credit as the Receiving Party
           determines acting in good faith will leave the Receiving Party (after
           that reimbursement) in no better or worse position in respect of its
           overall tax liabilities than it would have been in if the Paying 
           Party had not been required to pay such Tax.  

      (c)  Notwithstanding anything else herein contained, the EchoStar Parties
           covenant to use their commercially reasonable efforts to obtain a
           waiver of Taxes which may otherwise be payable in respect of any
           services rendered by them to ExpressVu hereunder from Revenue Canada
           pursuant to Regulation 105 of the INCOME TAX ACT (Canada) and the
           equivalent provisions of any applicable provincial income tax
           legislation. 

35.13 INTEREST ON OVERDUE PAYMENTS.  If a party hereto fails to pay any sum
payable hereunder when due in accordance with the provisions of this Agreement,
such party shall be liable to pay interest on the overdue amount at the rate of
24% per annum, which interest shall accrue daily from the date when payment
becomes overdue until payment of the overdue amount has been paid in full. 

35.14 EQUITABLE RELIEF.  The parties hereto acknowledge that damages may not
be an adequate remedy if a party breaches its obligations hereunder and,
accordingly, that any party hereto may seek an order for specific performance,
an injunction or other equitable remedy, to ensure the performance by any other
party hereto of its obligations hereunder and that such remedy may be sought in
lieu of or in addition to damages.

SCHEDULE 14:   SUB-LICENSING AGREEMENT RELATING TO LICENSED TRADE MARKS

                         TRADEMARK SUB-LICENSE AGREEMENT


          THIS TRADEMARK SUB-LICENSE AGREEMENT (the "Agreement") is made and
entered into as of the ________ day of _____________ , 199_ by and between
ExpressVu Inc. ("ExpressVu"), a corporation incorporated under the laws of
Canada, with a place of business at Suite 1008, 1290 Central Parkway West,
Mississauga, Ontario, Canada and ________________________________, a
corporation organized under the laws of _________________________, with its
principal place of business at ____________________________________________
("Sub-licensee").

A.   ExpressVu is in the business, among other things, of providing direct-to-
home satellite services to subscribers in the geographic territory of Canada
("DTH Services");

B.   ExpressVu has obtained the Canadian rights to certain trademarks, service
marks and trade names (the "Trademarks") of Echostar Communications Corporation
and its affiliates ("Echostar"); and

C.   Sub-licensee desires to be permitted to use such Trademarks as ExpressVu,
in its sole discretion, may authorize from time to time, under a non-exclusive
sub-license, to solicit orders for ExpressVu DTH Services;

               NOW THEREFORE, the parties hereto agree as follows:

1.   ExpressVu hereby grants to Sub-licensee a non-exclusive, non-transferable,
revocable sub-license (the "Sub-license") to use the Trademarks and such other
trademarks as ExpressVu may from time to time expressly in writing permit the
Sub-licensee to use during the term of this Agreement, and no other term or
license whatsoever, in its local advertising and promotional materials and at
its business locations.  Sub-licensee shall have no right to use the logos,
service marks and trademarks of any programming providers, other than the logos,
services marks and trademarks of programming providers that are contained in the
advertising and promotional material provided to Sub-licensee by ExpressVu.  No
such materials shall indicate that any agreement of agency, partnership, joint
venture, franchise or of exclusive or non-exclusive distributor exists between
Sub-licensee and ExpressVu or Sub-licensee and Echostar, unless ExpressVu and
Sub-licensee or Sub-licensee and EchoStar, as applicable, enter into a separate
written agreement permitting Sub-licensee to do so.  Notwithstanding the above,
Sub-licensee shall provide to ExpressVu, at least thirty (30) days prior to
first use, an example of any advertising or promotional materials in which Sub-
licensee intends to use any Trademarks, and any such other trademarks, which use
has not, within the past twelve months, been approved by ExpressVu in exactly
the form intended for use.  ExpressVu may reject and prohibit Sub-licensee from
using such materials, for any reason or reasons in its sole discretion.  If Sub-
licensee is required to, but fails to provide ExpressVu with proposed
advertising or promotional materials at least thirty (30) days prior to first
use, ExpressVu shall have just cause to immediately 

<PAGE>

                                    -2-


terminate the Sub-license by providing written notice to the Sublicensee to that
effect.  This Agreement is not intended, nor shall it be construed, as creating
any agreement of agency, partnership, joint venture, franchise or of exclusive
or non-exclusive distributor, or as creating any obligation on the part of
ExpressVu or EchoStar to enter into any such agreement with Sub-licensee. 
Further, this Agreement is not intended, nor shall it be construed, as providing
any rights to Sub-licensee to purchase or sell products or programming
manufactured and/or distributed by ExpressVu or Echostar.  Sub-licensee
expressly recognizes and agrees that any goodwill now existing or hereafter
created through any sales by Sub-licensee of products or programming
manufactured and/or distributed by ExpressVu or Echostar, shall inure to the
sole benefit of ExpressVu or Echostar, as applicable.  This Sub-license shall be
effective until terminated by either party in accordance with its terms, or
until termination of (i) the dealer agreement between ExpressVu and the Sub-
licensee or (ii) the license of the Trademarks granted by Echostar to ExpressVu.

2.   The Sub-license granted by ExpressVu is granted to Sub-licensee and its
Affiliates only.  Sub-licensee has no authority to transfer or grant any sub-
sub-license to any other entity or individual for any reason, and if Sub-
licensee does so, such action shall terminate the Sub-license granted herein, at
ExpressVu's option, at any time thereafter.  Sub-licensee shall immediately
cease using Trademarks upon termination or expiration of this Agreement for any
reason.  Upon expiration or termination of this Agreement, at ExpressVu's
option, Sub-licensee shall immediately destroy or deliver to ExpressVu any and
all advertising and promotional materials in Sub-licensee's possession with
Trademarks on them.  If ExpressVu requests destruction of advertising and
promotional materials, Sub-licensee shall promptly execute an affidavit
representing at a minimum that such materials were destroyed, and the date and
means of destruction.

3.   Sub-licensee expressly recognizes and acknowledges that the Sub-license, as
well as any past use of the Trademarks in any manner whatsoever by Sub-licensee
(including but not limited to use on signs, business cards or in
advertisements), shall not confer upon Sub-licensee any proprietary rights or
interest to any Trademarks including, but not limited to, any existing or future
goodwill in the Trademarks.  All goodwill in the Trademarks shall inure to
ExpressVu's or EchoStar's sole benefit, as the case may be.  Further, Sub-
licensee waives any and all past, present or future claims it has or might have
to the Trademarks, and acknowledges that as between ExpressVu, Echostar and Sub-
licensee, ExpressVu has the exclusive license to use the Trademarks in Canada,
and that Echostar retains full ownership of the Trademarks notwithstanding the
Sub-license granted herein.  Sub-licensee's obligations in this paragraph shall
survive the expiration or termination of this Agreement.

4.   Nothing in this Agreement shall be construed to bar ExpressVu or Echostar
from protecting their respective rights to the exclusive license or the
ownership and use, as the case may be, of the Trademarks against infringement
thereof by any party or parties, including Sub-licensee, either during the term
of this Agreement or following any expiration or termination of Sub-licensee's
right to use the Trademarks pursuant to this

<PAGE>

                                    -3-


Agreement.  Sub-licensee will promptly and fully advise ExpressVu of any use of
any mark that may appear to infringe the Trademarks.  Sub-licensee will also
fully co-operate with ExpressVu or Echostar in defense and protection of the
Trademarks, at the expense of ExpressVu or Echostar, as the case may be. 
Similarly, nothing in this Agreement shall be construed to require that
ExpressVu or Echostar take any action to protect the Trademarks in any instance,
and ExpressVu and Echostar shall not be liable to Sub-licensee in any manner
whatsoever for failure to take any such action.

5.   Sub-licensee shall indemnify and hold harmless ExpressVu from and against
all losses, damages, costs and expenses (including, without limitation,
reasonable legal costs and expenses) which ExpressVu may suffer or incur arising
out of or resulting from any claim or action against ExpressVu by a third party
arising from any violation by the Sub-licensee of the terms of this Sub-license
or unauthorized use of the Trademarks.

6.   This Agreement shall continue for a period of time equal to the term of any
dealer agreement between ExpressVu and Sub-licensee, unless terminated earlier
for a reason provided herein.

7.   Notwithstanding that EchoStar is not a signatory to this Sub-license, the
parties hereto acknowledge that EchoStar is a beneficiary of the agreements and
covenants contained herein and agree that EchoStar may enforce such agreements
and covenants on its own behalf (and at its own cost and expense) as if it were
a party hereto.  

8.   Any and all disputes, claims or actions that may arise under or out of this
Agreement shall be governed, interpreted and enforced in accordance with the
laws of the Province of Ontario and the laws of Canada applicable therein.

9.   This Agreement may be executed in two or more counterparts, each of which
shall be an original, but all of which together shall constitute one and the
same instrument.


          IN WITNESS WHEREOF, the parties hereto have executed this Agreement by
their duly authorized representatives as of the day and year above first
written.
