            2.10  Future Products.

                  SKYSTREAM agrees to use commercially reasonable efforts to
develop a conditional access scrambling product for ATSC transmission. The
specifications for such product are to be established by mutually agreement of
the Parties by August 31, 1999. HARRIS shall have the right to include such
product, as an Exclusive Product under the terms of this Agreement at a mutually
agreed upon price and such product shall become a Product hereunder.

      3.    SOFTWARE

            3.1   Authorization. SKYSTREAM warrants and represents that, as of
the date of this Agreement and as of the date of delivery of any Products
hereunder, SKYSTREAM has the authority to sell the Products and distribute all
the software accompanying the Products to HARRIS and End-User customers of
HARRIS, subject only to the acceptance of the terms of such end-user software
licenses as may accompany the Products by the End User.

            3.2   Limited Distribution. HARRIS is permitted to market and
distribute SKYSTREAM Software, and any other software accompanying the Products,
only in connection with the sale of the Products to the End User.

            3.3   End User Software License.

                  (a)   HARRIS agrees:

                        (i)   to include the following language in all sales
quotations and offers to sell the Products:

"THE [NAME OF PRODUCT] IS SOLD SUBJECT TO THE TERMS OF ONE OR MORE END USER
SOFTWARE LICENSES. THE USE OF THE [NAME OF PRODUCT] IS CONTINGENT UPON THE
ACCEPTANCE BY THE PURCHASER OF THE TERMS OF SUCH END USER SOFTWARE LICENSES."

                        (ii)  to provide a copy of the "End User Software
License", in the form attached hereto as Exhibit A, and such other end user
software licenses required for use of the Products, as may be provided by
SKYSTREAM from time to time, to any potential purchaser who shall request a copy
prior to sale;

                        (iii) to package and to install the Products in such a
manner that HARRIS' customer is provided with a meaningful opportunity to review
and agree to the End User Software License and other end user software licenses
accompanying the Products before installing or using any of the Products; and


                                      -5-
<PAGE>   10

                        (iv)  to accept for return and refund any unused
Products in the event that HARRIS' customer does not agree to accept any of the
terms of the End User Software License or the terms of any other software
license required to use the Products. SKYSTREAM shall accept the return such
unused Product and refund the Price to HARRIS.

                  (b)   In consideration of SKYSTREAM's not requiring a written
End-User Software License signed by HARRIS' customer as a precondition to the
sale or transfer of the Products, HARRIS agrees to indemnify SKYSTREAM for any
and all damages that may arise as a result of HARRIS' breach of Section 3.3(a).

            3.4   License Only. Notwithstanding the use herein of the word
"sell" and variants thereof, all Software is licensed to HARRIS and the End User
and is not sold. SKYSTREAM, or the licensors through which SKYSTREAM obtained
the rights to distribute Software, retain title to the Software, whether the
Software is separate or combined with any other products, including HARRIS'
products, and HARRIS shall transfer Software only to the extent that such
transfer is incidental to the resale or lease of the Products. The End User is
licensed by SKYSTREAM directly to use the Software solely in conjunction with
the use of the Products and further subject to the terms of the End User
Software License.

            3.5   Proprietary Software. The Software is proprietary to SKYSTREAM
and/or its suppliers and is copyrighted. Without SKYSTREAM's prior written
approval, HARRIS shall not separate the Software from the Products as shipped by
SKYSTREAM, nor shall HARRIS disassemble, de-compile, reverse-engineer, copy,
modify, or otherwise change any of the Software or its form. HARRIS shall
protect the Software from any disclosure or use in violation of this Agreement
in accordance with Exhibit A. HARRIS shall not be entitled to receive Source
Code.

      4.    TERMS AND CONDITIONS OF SALE

            4.1   Applicability of Terms and Conditions of Sale.

                  (a)   SKYSTREAM agrees to sell Products to HARRIS in
accordance with the terms and conditions of this Agreement. Specific quantities
of the Products shall be ordered by HARRIS for purchase by the placement of a
Purchase Order. In the event HARRIS requests a cancellation of a Purchase Order
prior to SKYSTREAM's acceptance, SKYSTREAM shall accept HARRIS' cancellation
with no cancellation fees accessed.

                  (b)   Within five (5) business days after the receipt of the
Purchase Order, SKYSTREAM shall by facsimile either accept or reject the
Purchase Order. Unless otherwise specified in this Agreement, any Purchase Order
accepted by SKYSTREAM ("Order"), shall be binding upon the Parties and (except
as permitted herein) may not be altered, amended, modified or canceled without
the prior written consent of HARRIS and SKYSTREAM. In the event SKYSTREAM
rejects a Purchase Order, the Parties agree to discuss mutually acceptable
conditions

                                      -6-
<PAGE>   11

for the Purchase Order and Acceptance. In the event HARRIS requests a
cancellation of an accepted Purchase Order, the Parties agree to discuss a
mutually equitable settlement as a result of said cancellation.

                  (c)   No terms or conditions set forth in the Purchase Order,
to which notice of objection is hereby given, or is stated in any future
correspondence between HARRIS and SKYSTREAM shall alter or supplement this
agreement unless both Parties have agreed in writing to modify this Agreement,
which requirement may be satisfied by acceptance of a term contrary to this
Agreement in a Purchase Order by confirmatory memorandum from SKYSTREAM.
Neither SKYSTREAM's commencement of performance or delivery shall be deemed or
construed as acceptance of additional or different terms and conditions
contained in a Purchase Order.

            4.2   Price.

                  (a)   Unless otherwise stated in writing by SKYSTREAM, all
prices quoted shall be exclusive of transportation, insurance, federal, state,
local, use, sales, property (ad valorem) and similar taxes or duties now in
force or hereafter enacted. HARRIS agrees to pay all taxes, fees or charge of
any nature whatsoever imposed by any governmental authority on, or measured by,

or invoiced. In the event that SKYSTREAM is required to collect the foregoing,
such amounts will appear as separate items on SKYSTREAM's invoice. HARRIS agrees
to provide SKYSTREAM with a valid resale certificate for the Products purchased
for resale. The initial pricing paid by HARRIS to SkyStream for Products is
listed in Exhibit D. Nothing in this Agreement will be construed to restrict
HARRIS' ability to set prices to its customers.

      HARRIS should supply the sending Bank Information, ABA & Account # to show
where the money is coming from.

                  (c)   Until the purchase price and all other charges payable
to SKYSTREAM hereunder have been received in full, SKYSTREAM hereby retains, and
HARRIS hereby grants to SKYSTREAM, a security interest in the Products delivered

documents reasonably requested by SKYSTREAM to perfect and protect such security
interest.

                  (d)   Should HARRIS become delinquent in the payment of any
undisputed sum due hereunder, SKYSTREAM shall not be obligated to continue
performance hereunder, including without limitation shipment of any previous
Orders.

                  (e)   HARRIS warrants to SKYSTREAM that it is financially
solvent on the date on which it places a Purchase Order and expects to be
solvent on the date of receipt of shipment. SKYSTREAM reserves the right to
change the credit terms provided herein, when in SKYSTREAM's opinion the
financial condition or previous payment record of HARRIS so warrants.

            4.5   Forecast and Delivery Dates.

                  (a)   Standard lead times for Purchase Orders placed by HARRIS
shall be [*] for Products included in the purchase forecast provided to

an additional ninety (90) day period beyond the date of open Purchase Orders
that exist at any given time.

                  (d)   Subject to Section 4. 1 (c), all shipments are subject
to SKYSTREAM's availability schedule. SKYSTREAM will use commercially reasonable
efforts to meet any delivery date(s) requested in Purchase Order; provided
however, that SKYSTREAM will not be liable under any circumstances for its
failure to meet such delivery date(s). Any delivery dates provided by SKYSTREAM
to HARRIS pursuant to a Purchase Order are best estimates only, however delivery
date in an Order which has been confirmed in writing by SKYSTREAM shall be firm.
SKYSTREAM shall have the right to make partial shipments and payment therefore
shall be made in the manner described in Section 4.3 above.

                  (e)   In the event HARRIS requests an acceleration in the
delivery of the Products SKYSTREAM will make reasonable efforts to accommodate
accelerations impacted by materials constraints; which may include without
limitation: material availability, capacity, and personnel resources. SKYSTREAM
and HARRIS will mutually agree on the applicable price adjustments if
accelerations result in increased costs due to procurement of material from
distribution and express handling.

            4.6   Packing. All Products shall be packed, if appropriate, for
shipment and storage in accordance with standard commercial practices. All
packing will conform to requirements of carrier's tariffs. When special or
export packaging is requested or, in the opinion of SKYSTREAM, required under
the circumstances, the cost of such special export packaging, if not set forth

with HARRIS' logo and markings including the number of Purchase Order, shipment
weight, name of Products, handling and loading instructions and an itemized
packing list specifying the number of units, Purchase Order, serial numbers with
each shipment by pallet. SKYSTREAM will provide test date of bulk packaging for
evaluation and approval. The units shall be individually packed in HARRIS
labeled boxes.

accepted by HARRIS unless HARRIS provides written notice to SKYSTREAM to the
contrary within thirty (30) days from the date of delivery to the F.O.B. point.

and the terms and conditions that apply to warranty returns under Section 4.8
shall apply to returns under this Section 4.6.

            4.8   Changes and Cancellations.

                  (c)   If HARRIS terminates Orders in whole or in part because
of SKYSTREAM's failure to timely deliver, HARRIS' sole remedy shall be
entitlement to cancel the undelivered quantity of any Order.

                  (d)   No cancellation of any Order for default shall be
effective unless SKYSTREAM has failed to correct such alleged default within
thirty (30) days after receipt by SKYSTREAM of a written notice by HARRIS of
such default and no cancellation fee shall be accessed against HARRIS.

            4.9   Limited Warranty

                  (a)   The Products are warranted against defects in material,
design and workmanship for a period of fourteen months from the date of delivery
to FOB point. This limited warranty does not cover the results of accident,
abuse, neglect, improper testing, vandalism, acts of God, use contrary to
specifications or instructions, or repair or modification by anyone other than
SKYSTREAM, HARRIS or SKYSTREAM's authorized agents. SKYSTREAM SHALL HAVE NO
OBLIGATION UNDER THIS WARRANTY, AND MAKES NO REPRESENTATION AS TO PRODUCTS THAT
HAVE BEEN MODIFIED CONTRARY TO PRODUCT SPECIFICATIONS ("MODIFIED") BY HARRIS OR
ITS END USERS. The foregoing warranty extends only to HARRIS and End Users
purchasing Products through an authorized sales channel of HARRIS, and not other
End Users. The foregoing warranty does not apply to any used or Modified
Products, or software within the Products, which is subject to the end user
software licenses.

                  (b)   If the Product does not conform to the foregoing
warranties, HARRIS or HARRIS' End User may, at its own risk and expense, return
the allegedly defective Product directly to SKYSTREAM during the Warranty
Period. In order to do so, HARRIS or HARRIS' End User must first notify
SKYSTREAM in writing of the alleged defect and request a return material
authorization ("RMA") number. Within five (5) days of its receipt of the RMA
number, HARRIS or HARRIS' End User shall ship to SKYSTREAM the allegedly
defective Product, freight prepaid, to SKYSTREAM, and shall include a notation
of the RMA number. Any Products returned to SKYSTREAM without an authorized RMA
number may be returned to HARRIS or HARRIS' End User, freight collect. Upon
receipt of the Product, SKYSTREAM, at its option, will repair or replace the
Product and ship the repaired or replaced Product to HARRIS at SKYSTREAM's
expense and risk, or refund the purchase price. If SKYSTREAM determines that any
returned Product conformed to the warranties, SKYSTREAM will return the Product
to HARRIS or HARRIS' End User, at their expense and risk, along with a written
statement setting forth the basis for SKYSTREAM's conclusion that the returned
Product was not defective, and HARRIS or HARRIS' End User agrees to pay
SKYSTREAM's reasonable costs of handling and testing.

                  (c)   THE REMEDIES PROVIDED HEREIN ARE HARRIS' AND HARRIS' END
USERS' SOLE AND EXCLUSIVE REMEDIES FOR BREACH OF WARRANTY BY


                                      -11-

SKYSTREAM. SKYSTREAM SPECIFICALLY DISCLAIMS ALL OTHER EXPRESS, IMPLIED OR
STATUTORY WARRANTIES, INCLUDING ANY IMPLIED WARRANTIES OF FITNESS FOR A
PARTICULAR PURPOSE, MERCHANTABILITY OR NONINFRINGEMENT. NO PERSON IS AUTHORIZED
TO MAKE ANY OTHER WARRANTY OR REPRESENTATION CONCERNING THE PERFORMANCE OF THE
PRODUCTS OTHER THAN AS PROVIDED IN THIS SECTION.

            4.10  Import/Export.

                  HARRIS agrees that it will not in any form export, re-export,
resell, ship or divert directly or indirectly any Product or technical data or
Software furnished hereunder to any country for which the United States
Government or any government agency requires an export license or other
governmental approval without first obtaining such license or approval.

            4.11  Restricted Use.

                  SKYSTREAM's Products may produce a reduction and loss of data
and therefore are not sold for use in medical equipment, avionics, nuclear
applications, or other high-risk applications where malfunctions or loss of data
could result directly in personal injury to human beings. HARRIS agrees not to
use, to contractually bind its customers not to use, the Products in such
applications, and HARRIS agrees to indemnify SKYSTREAM and to hold SKYSTREAM
harmless from and against any liability arising out of HARRIS' failure to
contractually bind its customers in the manner previously described.

            4.12  Spares available for 7 Years.

                  (a)   SKYSTREAM shall continue to make available to HARRIS
Spare Parts identified in Exhibit E, for a period of seven (7) years after the
discontinuance of manufacturing of the Product by SKYSTREAM, at SKYSTREAMs
current prices for such Spare Parts as SKYSTREAM may change from time to time
(current prices as of the Effective Date are listed on Exhibit E), and HARRIS
may order such Spare Parts for delivery during such period. If after expiration
of this seven (7) year period, SKYSTREAM decides to discontinue manufacture of
any Spare Parts manufactured directly by it, SKYSTREAM shall immediately provide
written notice to HARRIS of its intention. Upon receipt of SKYSTREAM's written
notice, HARRIS shall have sixty (60) days in which to order additional
quantities of any such Spare Parts for delivery by SKYSTREAM not later than six
(6) months after receipt of the notice.

                  (b)   Within 90 days of such notice and if HARRIS desires to
have Spare Parts manufactured after SKYSTREAM has discontinued manufacture of
the parts, SKYSTREAM shall either manufacture them for HARRIS at a reasonable
Cost Plus Fee basis or SKYSTREAM shall provide HARRIS with appropriate
documentation, tooling and the rights to use the documentation and tooling to
have the parts manufactured by HARRIS and/or it's contractor.

            4.13  Product Changes.

                  (a)   SKYSTREAM may, at any time prior to shipment, make
changes in NonExclusive Products. SKYSTREAM may modify the Non-Exclusive Product
drawings and specifications, as they may be set forth in the relevant product
specification sheet (the "Specifications"), or substitute products of later
design. SKYSTREAM guarantees that such modifications or substitutions will not
impact upon form, fit, or function under normal and proper use of the ordered
Product as provided in the Specifications. With respect to changes,
modifications, and substitutions that do impact the form, fit, or function of
Non-Exclusive products, SKYSTREAM shall notify HARRIS in writing thirty (30)
days prior to the date the changes become effective and HARRIS shall notify
SKYSTREAM of any objections thereto before the effective date of the change; if
HARRIS fails to notify SKYSTREAM of any such objections, HARRIS shall be deemed
to have consented to such change.

                  (b)   SKYSTREAM shall inform HARRIS on a periodic basis of any
planned changes to the form, fit or function of Exclusive Products. Any changes,
modifications, and substitutions that impact the form, fit, or function of
Exclusive Products shall be mutually agreed upon by the Parties. HARRIS reserves
within its sole discretion, the right to accept or reject any such proposed
changes and to require SKYSTREAM to deliver the Exclusive Products in accordance
with the original Specifications of this Agreement.

                  (c)   Notice of any technical change to the Products shall be
provided to:

                  HARRIS Corporation

            4.14  Price Protection.

                  (a)   The Parties shall have established commercially viable
pricing for the purchase of the Products by HARRIS for resale. Commercial
viability shall be based on the competitiveness of the price paid by HARRIS to
SKYSTREAM and based on such purchase price, the ability of HARRIS to resell the
Products in the market place at a reasonable margin to HARRIS. In the event that
HARRIS believes that the purchase price no longer is commercially viable,



                                      -13-
<PAGE>   18

HARRIS shall notify SKYSTREAM in writing, and the Parties shall engage in good
faith negotiations to restructure the purchase price between them in order to
meet the goal of the commercial viability of the purchase price. The intent of
such good faith negotiations is the reduction of the purchase price between the
Parties which will enable HARRIS to meet resale market forces. At no time shall
such discussions or agreements allow SKYSTREAM to affect in any way, the HARRIS
resale price or other factors of the resale. Once SKYSTREAM accepts the Purchase
Order in Writing, at the quoted price, this price shall remain fixed as defined
in the Order unless the parties mutually agree to reduce the price.

                  (b)   Any adjustment in the price of the Products shall be
effective on Products not yet delivered to HARRIS by SKYSTREAM under outstanding
Orders. SKYSTREAM agrees to amend the Order accordingly.

            4.15  Service Agreements.

                  HARRIS shall have the opportunity to purchase, for resale to
End Users, the first year of SkySupport Service customer service, as listed in
Exhibit D under SkySupport Plan, at the time of each sale by Harris to an End
User. Such SkySupport may then be renewed on the nearest of February 15, May 15,
August 15 and November 15 following the one yew anniversary of the date of each
sale by Harris to End User. In the case of upgrades to a previously purchased
Product, in order for SkySupport to extend to the upgrade, the End User must
have purchased SkySupport on the Product, and must pay for SkySupport on the
upgrade. Where SkySupport is ordered on an upgrade, the first year of SkySupport
shall be assessed on the upgrade at the time of order by Harris and invoiced
with the upgrade, and thereafter collected at the time the SkySupport renewal is
payable on the Product for which the upgrade was purchased.

      5.    MAINTENANCE, SUPPORT, AND TRAINING.

            5.1   By HARRIS.

      HARRIS agrees to offer all End-Users one of two maintenance and support
plans to technically support the Products sold to the End-Users as follows:

                  (a)   a service plan that is substantially similar to the
SkySupport customer service program that is offered by SKYSTREAM to its direct
customers. A copy of the plan, as well as the fee structure is listed in Exhibit
D under SKYSUPPORT PLAN.

                  (b)   a standard 12-month warranty period, of which the
services available to the End-Users as well as the fee structure are listed in
Exhibit D under STANDARD WARRANTY.

            5.2   By SKYSTREAM.



                                      -14-
<PAGE>   19


      SKYSTREAM will not be responsible for providing support to the End User.
SKYSTREAM will provide HARRIS with:

                  (a)   commercially reasonable efforts to correct any
non-conformity with the software Feature Specification Documents for the
applicable versions of the software;

                  (b)   every six (6) months, at a mutually agreeable location
at no cost to HARRIS: factory and field service training, to consist of a
minimum of two business days of training, and sales and product line staff
training, to consist of at least one, four-hour session. Factory and field
service training sessions given pursuant to this section may be attended by up
to 5 HARRIS personnel. Sales and product line staff training shall be attended
by a reasonable number of HARRIS personnel or HARRIS distributors. Each Party
agrees to pay the travel and living expenses of such Party's own personnel
associated with the training;

                  (c)   SKYSTREAM agrees to provide reasonable access to
SKYSTREAM's technical personnel for inquiries from HARRIS relating to the
Products during standard SKYSTREAM business hours, generally Monday through
Friday from 9:00 am. to 5:00 p.m. Pacific Standard Time, and SKYSTREAM agrees to
respond to any HARRIS inquiry within eight business hours;

                  (d)   additional training and support services as the Parties
shall negotiate in good faith and mutually agree upon.

      6.    CONFIDENTIALITY.

            6.1   Obligations. Each party agrees that it will not disclose to
any third party or use any Products or other Confidential Information disclosed
to it by the other party, except to carry out its rights and obligations under
this Agreement, and that it will take all reasonable measures to maintain the
confidentiality of all Confidential Information in its possession or control,
which will in no event be less than the measures it uses to maintain the
confidentiality of its own information of similar importance. "Confidential
Information" includes (i) all written information labeled confidential or
proprietary and (ii) oral information that is designated by a party as
confidential or proprietary in writing within a reasonable time of its
disclosure.

            6.2   Exceptions. "Confidential Information" will not include
information that:

                        (i)   is in or enters the public domain without breach
of this Agreement;

                        (ii)  is lawfully obtained by the receiving party
without breach of a nondisclosure obligation;




                                      -15-
<PAGE>   20

                        (iii) is independently developed or already in the
possession of the receiving party as shown by the receiving party's
contemporaneous records; or,

                        (iv)  is required by law to be disclosed, provided that
the receiving party gives prompt written notice of such requirement prior to
disclosure: or

                        (v)   was known to the receiving party at the time it
was submitted;

      The obligations and restriction contained in this Section 6.1 shall expire
10 years after the Effective Date or 3 years after expiration or termination of
this Agreement, which ever is later.

            6.3   Injunctive Relief. Each party acknowledges that the improper
disclosure of the other's Confidential Information could cause substantial harm
to the other party that could not be remedied by the payment of damages alone.
Accordingly, either party will be entitled to preliminary and permanent
injunctive relief and other equitable relief for any breach of this Agreement or
misuse of Confidential Information by SKYSTREAM, HARRIS or the End User, as
applicable.

            6.4   Disclosure Warranty. Each party warrants that it has the full
power and authority to supply and to disclose Confidential Information to the
other party, and that such Confidential Information has not been improperly or
unlawfully acquired.

            6.5   Disclosure Indemnification. Each party agrees to indemnify the
other party against, and to hold the other party harmless of and from, any loss,
cost, damage, liability, suit, judgment, or expense, including legal fees
(collectively, "Harm") arising out of any breach of the warranties set forth in
Section 6.4.

      7.    INTELLECTUAL PROPERTY RIGHTS

            7.1   Ownership. SKYSTREAM and/or its vendors shall own all right,
title, and interest in the Software and documentation, all Intellectual Property
Rights therein, and all Intellectual Property Rights in the Products, including
all changes and improvements requested or suggested by HARRIS in the support and
maintenance of the Products. SKYSTREAM acknowledges that HARRIS shall own all
right, title, interest and Intellectual Property Rights in all products or
inventions developed entirely by HARRIS except those which are based upon or
derived from the Products, Software, documentation, Confidential Information or
trade secret information of SKYSTREAM, or those developed by Harris personnel
who have used the Products and/or Software that are based upon or derived from
the Products and/or Software at the time of conception or reduction to practice
of the invention to the Products, or from research or development of SKYSTREAM
that has been a subject of public disclosure or disclosure to Harris pursuant to
this Agreement.


                                      -16-
<PAGE>   21
            7.2   Limited Use. The Products are offered for sale and are sold by
SKYSTREAM subject in every case to the condition that such sale does not convey
any license expressly or by implication, to manufacture, reverse engineer,
duplicate or otherwise copy or reproduce any of the Products or any part
thereof.

            7.3   Notices. HARRIS will not delete or in any manner alter the
Intellectual Property Rights notices of SKYSTREAM and its suppliers, if any,
appearing on the Products as delivered to HARRIS.

            7.4   HARRIS' Duties. HARRIS will take customary measures in the
marketing and distribution of the Products to provide notices of SKYSTREAM's
copyrights and trademarks in the Products, no less than the extent to which
HARRIS protects its copyrights and trademarks in HARRIS' Products, and will, to
the extent lawful, report promptly to SKYSTREAM any infringement of such rights
of which HARRIS becomes aware.

            7.5   Trademarks. Subject to the terms and conditions of this
Agreement, SKYSTREAM grants HARRIS a nonexclusive license for the term of this
Agreement to use the Marks in HARRIS' marketing of the Products, provided that
such use is in accordance with SKYSTREAM's trademark usage guidelines then in
effect. Such use must reference the Marks as being owned by SKYSTREAM. Nothing
in this Agreement grants HARRIS ownership or any rights in or to use the Marks,
except in accordance with this license, and HARRIS' use of the Marks will inure
to the benefit of SKYSTREAM. The rights granted to HARRIS in this license will
terminate upon any termination or expiration of this Agreement. Upon such
termination or expiration, HARRIS will no longer make any use of any Marks.
SKYSTREAM will have the exclusive right to own, use, hold, apply for
registration for, and register the Marks during the term of, and after the
expiration or termination of, this Agreement; HARRIS will neither take nor
authorize any activity inconsistent with such exclusive right.

      8.    INFRINGEMENT INDEMNITY

            8.1   SKYSTREAM Indemnification and Defense. Subject to the
limitations hereinafter set forth, HARRIS agrees that SKYSTREAM has the right to
defend, or at its option to settle, and SKYSTREAM agrees, at its own expense, to
defend or at its option to settle, any claim, suit or proceeding (collectively,
"Action") brought against HARRIS, its customers or its End Users alleging that
the use or distribution of the Products infringes or misappropriates any United
States patent, copyright or trade secret. SKYSTREAM shall have sole control of
any such Action or settlement negotiations shall, and SKYSTREAM agrees to pay,
subject to the limitations set forth in Sections 7 and 8, all related costs,
expenses and attorney fees and any settlement costs or final judgment entered
against HARRIS or its End Users as a result of such infringement. HARRIS agrees
that SKYSTREAM at its sole option shall be relieved of the foregoing obligations
unless HARRIS notifies SKYSTREAM promptly in writing of such Action and gives
SKYSTREAM



                                      -17-
<PAGE>   22

authority to proceed as contemplated herein, and, at SKYSTREAM's expense, gives
SKYSTREAM proper and reasonable information and assistance to settle and/or
defend any such Action. If the Products, or any part thereof, are, or in the
opinion of SKYSTREAM may become, the subject of any Action for infringement of
any United States patent, copyright or trade secret, or if a judicial or other
governmental authority enjoins the use or distribution of Products as a result
of an Action defended by SKYSTREAM, then SKYSTREAM may, at its option and
expense: (i) procure for HARRIS, its customers and End Users the right to
distribute or use, as appropriate, the Products; (ii) replace the Products with
other equivalent non-infringing Products; (iii) suitably modify the Products to
render such non-infringing; yet equivalent or (iv) if the foregoing alternatives
cannot be accomplished on a commercially reasonable basis as determined in
SKYSTREAM's sole discretion, require HARRIS to return such Products and refund
the aggregate payments paid therefor by HARRIS, less a reasonable sum for use
and damage. HARRIS shall indemnify and hold harmless SKYSTREAM from and against
any and all third party claims arising out of the distribution of Products after
SKYSTREAM has required HARRIS to return such Products or arising out of any
exclusions to SKYSTREAM's indemnification obligations set forth in Section 8.2.
SKYSTREAM shall not be liable for any costs or expenses incurred without its
prior written authorization.

            8.2   SKYSTREAM limitations. Notwithstanding the provisions of
Section 8.1 above, SKYSTREAM assumes no liability for (i) any infringement claim
(including without limitation combination or process patents) arising out of the
combination of a Product or use with other hardware, software or other items not
provided by SKYSTREAM to the extent such infringement would not have occurred
absent such combination or use; (ii) any infringement claims arising out of the
modification of the Products, or any part thereof, unless such modification was
made by SKYSTREAM; or (iii) any infringement claims arising out of SKYSTREAM's
compliance with HARRIS' specifications or designs.

            8.3   Entire Liability. THE FOREGOING PROVISIONS OF THIS SECTION 8
STATE THE ENTIRE LIABILITY AND OBLIGATION OF SKYSTREAM AND THE EXCLUSIVE REMEDY
OF HARRIS, ITS CUSTOMERS AND END USERS WITH RESPECT TO ANY ALLEGED INFRINGEMENT
OF COPYRIGHTS, TRADEMARKS, PATENTS OR OTHER INTELLECTUAL PROPERTY RIGHTS BY THE
PRODUCTS.

      9.    YEAR 2000 COMPLIANCE

including (software, firmware or documentation) furnished with the Products

all times before, during and after calendar year 2000, perform all functions
(including, without limitation, input, processing, calculating, comparing,
sequencing and output) related to or including dates (including the year 2000
and dates before and after the year 2000) without interruption. For purposes of
the foregoing, "without interruption" means, among other things, without
modification, loss of performance, loss of use, or work or


                                      -18-
<PAGE>   23

expense on the part of HARRIS or the End User, without changes in inputs,
output, data or other information in relation to dates arising in the Y2K and
beyond. Furthermore, when used in combination with other information technology,
each of the Products shall accurately process date/time data.

                  (b)   SKYSTREAM warrants to HARRIS that internal information
technology systems are Year 2000 Compliant so as to prevent interruption or
delay respecting the continuous and timely supply of products to HARRIS.

                  (c)   SKYSTREAM shall indemnify and hold harmless, HARRIS, its
employees, agents and third parties claiming under them from any and all
actions, claims, demands, suits, losses, damages, fines and penalties (except
where prohibited by law), judgments, expenses (including reasonable attorney's
fees), and causes of action of every character, whether in tort, contract or
otherwise which results from the failure or the alleged failure of SKYSTREAM to
furnish "Year 2000 Compliant" software as stated herein. HARRIS shall notify
SKYSTREAM in writing immediately upon being given notice of any such action or
claim and HARRIS shall be afforded the opportunity of participating in any legal
defense undertaken by SKYSTREAM.

      10.   LIMITATIONS OF LIABILITY.

            10.1  Total Liability. EXCEPT AS SET FORTH IN SECTION 8 AND EXCEPT

HARRIS' CUSTOMERS OR END USERS, NOR SHALL HARRIS BE LIABLE TO SKYSTREAM, FOR ANY
SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES, WHETHER BASED ON BREACH OF
CONTRACT, TORT (INCLUDING NEGLIGENCE), PRODUCT LIABILITY, OR OTHERWISE, AND
WHETHER OR NOT SUCH PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGE.
THESE LIMITATIONS SHALL APPLY NOTWITHSTANDING ANY FAILURE OF ESSENTIAL PURPOSE
OF ANY LIMITED REMEDY.

            10.3  No Warranty. EXCEPT AS SET FORTH IN SECTIONS 4.9, 8 AND 9,
SKYSTREAM MAKES NO WARRANTY, EXPRESS OR IMPLIED, IN CONNECTION WITH THE
PRODUCTS, INCLUDING THE RESULTS AND PERFORMANCE THEREOF, INCLUDING WITHOUT
LIMITATION ANY IMPLIED WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR
PURPOSE OR NONINFRINGEMENT.

efforts in the preparation of a press release, mutually acceptable to both

matter hereof without the express approval of the other party.

            12.2  Assignment. The rights and liabilities of the Parties hereto
shall bind and inure to the benefit of their respective successors, executors
and administrators, as the case may be provided that no Party may assign or
delegate its obligations under this Agreement either in whole or in part,

foregoing, nothing herein shall preclude an Assignment by any Party to a Party's
affiliated subsidiary or parent company.

construed in accordance with the laws of the State of California applicable to
agreements between California residents entered into and to be performed
entirely within California, without reference to conflict of law principles. Any
dispute or claim arising out of this Agreement will be resolved by binding
arbitration in the city and state of Denver, Colorado in accordance with the
complex commercial litigation rules of the American Arbitration Association. The
arbitrator shall not limit, expand or modify the terms of the Agreement nor
award damages in excess of compensatory damages, and each Party waives any claim
to such excess damages. Notwithstanding the arbitrator will have the power to
grant any form of relief, including preliminary and permanent injunctive relief,
which a judge in California with jurisdiction could fashion, and judgment on any
award may be entered in any court in California with jurisdiction. Nonetheless,
the Parties may seek temporary or permanent


                                      -21-
<PAGE>   26

injunctive relief from any court in California with jurisdiction without
breaching this Section 12.3 or otherwise abridging the authority of the
arbitrator.

            12.4  Severability. If any provision of this Agreement is found
invalid or unenforceable, that provision will be enforced to the maximum extent
permissible and the other provisions of this Agreement will remain in force.

            12.5  Force Majeure. Except for payments due under this Agreement,
neither party will be responsible for any failure to perform due to causes
beyond its reasonable control (each a "Force Majeure"), including, but not
limited to, acts of God, war, riot, embargoes, acts of civil or military
authorities, denial of or delays in processing of export license applications,
fire, floods, earthquakes, accidents, strikes, or fuel crises, provided that
such party gives prompt written notice thereof to the other party. The time for
performance will be extended for a period equal to the duration of the Force
Majeure, but in no event longer than sixty days.

            12.6  Notices. All notices under this Agreement will be deemed given
when delivered personally, or sent by confirmed facsimile transmission, or sent
by certified or registered U.S. mail or recognized express courier, return
receipt requested, to the address as first shown on this Agreement or as may
otherwise be specified by either party to the other in accordance with this
section.

            12.7  Independent Contractors. The Parties to this Agreement are
independent contractors. There is no relationship of partnership, joint venture,
employment, franchise, or agency between the Parties. Neither party will have
the power to bind the other or incur obligations on the other's behalf without
the other's prior written consent.

            12.8  Waiver. No failure of either party to exercise or enforce any
of its rights under this Agreement will act as a waiver of such rights.

            12.9  Counterparts.

This Agreement may be executed in any number of counterparts, each of which
shall be enforceable against the party executing such counterpart, and all of
which together shall constitute one instrument.

            12.10 Entire Agreement

      This Agreement and its exhibits are the complete and exclusive agreement
between the Parties with respect to the subject matter hereof, superseding and
replacing any and all prior agreements, communications, and understandings (both
written and oral) regarding such subject matter. This Agreement may only be
modified, or any rights under it waived, by a written document executed by both
Parties.

CUSTOMER SERVICE PLAN FOR DIRECT CUSTOMERS

SkySupport is a customer service plan that offers world-class support to
SkyStream customers domestically and internationally. SkyStream offers a program
whereby the greatest effort is placed in fast response time to any issues that
emerge, 24 hours a day, and 7 days a week. SkyStream also employs proactive
efforts to keep SkySupport customers abreast of any new product developments or
code changes.

Because of the evolutionary architecture of the SkyStream Integrator series,
customers may find it useful to gradually add hardware or software features to
the base product. Customers can also purchase feature additions or an add-on
card for additional functionality. SkyStream offers all SkySupport customers
the opportunity to upgrade their products, even after the units are installed
in the field.

The SkySupport customer service plan is available to all direct customers of
SkyStream. The plan is supported on a per-unit basis, and is renewed annually.
SkySupport customers are also eligible to purchase product upgrades or training
for additional charges. This renewable 1-year plan (after ship date) shall
include the following three categories of support:

1. ULTRA-FAST RESPONSE TIME

2. PRODUCT UPGRADES

3. SKYSTREAM'S PRODUCT TRAINING PROGRAM

The SkySupport Service Plan is initially ordered at same time that the
equipment is purchased. SkySupport service is renewed automatically, unless
otherwise noted by the customer, every 12 months at the standard service rate
(per the most recent price list).

2. PRODUCT UPGRADES

SkyStream's products have a unique architecture that allows them to receive
hardware or software upgrades while installed in the field. Upgrades can range
from simple software patches to significant feature upgrades, all of which are
best treated under the SkySupport plan. Product Upgrades come in three
different categories, and will be clearly marked in all price lists:

LEVEL 1 UPGRADE: BUG FIXES

All software bug fixes will be documented and made accessible to all SkyStream
customers. Bug fixes are software patches that repair a known problem in the
current released code. Level 1 upgrades will be available [*], as long as
customers are using supported software releases. Typically, SkyStream will
provide support for the 2 most recent releases of its software. Customers using
unsupported versions of software will need to upgrade to the latest version to
receive code fixes, and non-SkySupport customers may need to pay [*] to upgrade.
Registered SkySupport customers will be pro-actively notified via email of any
upgrade within 30 days of production release date.

LEVEL 2 UPGRADE: FEATURE IMPROVEMENTS

Level 2 upgrades include all software improvements. Software improvements are
released on an ongoing basis to improve on an existing set of functions. See the
SkyStream price list to determine which features fall into this category. These
upgrades will be provided to SkySupport customers for [*] as long as customers
are using supported software releases.

LEVEL 3 UPGRADE: FEATURE ADDITIONS AND HARDWARE UPGRADES

Feature additions and hardware add-on card upgrades will be sold via SkyStream's
upgrade price list. Feature additions include software code upgrades that add
significant functionality to the existing product specification. See the
SkyStream price list to determine which features fall into this category. Only
authorized SkySupport personnel will administer Level 3 upgrades. Registered
SkySupport customers will be pro-actively notified via email of any upgrade
within 30 days of production release date.

SkyStream's Integrator family uses a flexible architecture that allows customers
to purchase a base system for immediate requirements, with an interest to
upgrade its functionality to a new platform in the future. For example, if a
customer purchases a DBN-35 ATSC IP Data Injector, and later wishes to upgrade
the product to support CAS Injection, he can do so by paying only an upgrade fee
as opposed to buying a new system (see upgrade price list for upgrade prices).

3.   SKYSTREAM'S PRODUCT TRAINING PROGRAM

of system installation. Customer operations and production staff receive
training on

SkyStream offers advanced training to customers that support and maintain their
SkyStream system. This training provides customers with the technical knowledge
and hands-on skills needed to use, configure, support and troubleshoot the
SkyStream system. This training is delivered at SkyStream's Corporate Training
Facility in Mt. View, CA.
