                  "The [name of Product] is sold subject to the terms on an End
                  User Software License. The use of the [name of Product] is
                  contingent upon the acceptance by the purchaser of the terms
                  of the End User Software License."

            (ii)  to provide a copy of the End User Software License, in the

                  who shall request a copy prior to sale;

           (iii)  to package and to install the Products in such a manner that
                  Reseller's customer is provided with a meaningful opportunity
                  to review and agree to the End User Software License before

            (iv)  to agree to accept for return and refund any unused Products

                  terms of any other software license required to use the
                  Products.

      In consideration of SkyStream's not requiring a written End-User Software
      License signed by Reseller's customer as a precondition to the sale or
      transfer of the Products, Reseller agrees to indemnify SkyStream for any
      and all damages that may arise as a result of (i) Reseller's breach of
      Section 3.2(a).

3.3   License Only. Notwithstanding the use herein of the word "sell" and
      variants thereof, all Software is licensed to the Reseller 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 Reseller Products, and Reseller 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.

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


                                      -4-

3.5  Software Revisions. In the event SKYSTREAM, at its sole discretion,
     provides Reseller with revised copies of the Software, Reseller shall,
     according to SKYSTREAM's instructions, replace copies of the Software from
     the Products with the revised Software. Reseller shall dispose of the
     replaced Software in accordance with SKYSTREAM's instructions. SKYSTREAM
     shall have the right to inspect Reseller's inventory of Software and
     replaced Software at any time on reasonable notice.

4.   MAINTENANCE, SUPPORT, AND TRAINING.

     support to the End User: installing the Products as needed; training the

     User, including problem analysis and using its reasonable efforts to
     provide solutions and error correction for the products consistent with
     Reseller's standard service and support policies and procedures.

     Reseller agrees to provide a substantially similar level of support to that
     SkyStream provides to its direct customers, which must include, at a
     minimum, 24x7 telephone support, and at least 2 hours of on-site training
     to the End User. A copy of SkyStream's direct SkySupport service agreement
     is attached in Exhibit E. Reseller agrees to use best efforts to ensure
     that training of Reseller's personnel occurs within the first 90 days of
     the execution of this Agreement. Reseller agrees to maintain a minimum of 2
     fully trained service personnel at all times, which personnel must attend
     training, to be paid for by Reseller, at least once every 12 months.

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

     (i)   commercially reasonable efforts to correct any non-conformity with
           the Software Feature Specification Document for the applicable
           version of the Software:

     (ii)  technical training, to consist of one training class given over one
           and one-half (1 1/2) eight-hour days and which may be attended by up
           to three Reseller personnel onsite at SKYSTREAM's Mountain View,
           California office, provided that Reseller pays the travel and living
           expenses of such personnel designated to receive the training, or at
           Reseller's headquarters, provided that Reseller pays the travel and
           living expenses of SKYSTREAM's training personnel; training class for
           additional personnel will be quoted by SKYSTREAM separately;

     (iii) upon continued payment of an annual Maintenance Fee (the "Maintenance
           Fee") in the amount currently set forth on Exhibit D, as SKYSTREAM
           may change from time to time, payable in full with each sale to
           Reseller and



                                      -5-
<PAGE>   6
               thereafter on the nearest of February 15, May 15, August 15 and
               November 15 following the one year anniversary of the date of
               each sale to Reseller, SKYSTREAM agrees to provide reasonable
               access to SKYSTREAM's technical personnel for inquiries from
               Reseller relating to the Products during standard SKYSTREAM
               business hours, generally Monday through Friday from nine a.m. to
               five p.m. Pacific Standard Time, and access to SKYSTREAM's
               technical call center 24 hours a day, 7 days a week, where
               SKYSTREAM agrees to respond to any Reseller inquiry within four
               business hours of initial call placement. In the case of upgrades
               to a previously purchased Product, the Maintenance Fee shall be
               payable on the upgrade at the time of sale to Reseller and
               thereafter at the time the Maintenance Fee is payable on the
               Product for which the upgrade was purchased. Payment of this
               recurring Maintenance Fee does not entitle Reseller or End User
               to, and shall not be construed as either full or partial payment
               for, software upgrades with new functionality as defined by
               SKYSTREAM;

          (iv) upon fourteen days notice, technical consulting services at a
               location to be designated by Reseller, at SKYSTREAM's current
               hourly rate for such services as may be adjusted by SKYSTREAM
               from time to time, provided that Reseller shall also reimburse
               SKYSTREAM for all associated travel and living expenses in
               connection with such services. SKYSTREAM's current technical
               consulting hourly rate is included on SKYSTREAM's price list for
               sales to Resellers, a copy of which is attached hereto as Exhibit
               D.

     4.3  Repairs Support. SKYSTREAM shall provide repair or replacement support
          for all equipment provided, at SKYSTREAM's then-current prices,
          pursuant to this Agreement for a period of at least five (5) years
          from delivery of a purchased unit, provided, however, that such
          replacement support may consist of equipment with comparable
          functionality as determined at SKYSTREAM's sole discretion.

     4.4  Quality Control System. Upon reasonable notice, SkyStream agrees to
          provide Reseller reasonable access to the manufacturing areas of
          SkyStream's facility for purposes of observing SkyStream's quality
          control procedures.

5.   CONFIDENTIALITY.

     5.1  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 all information designated by a party as


                                      -6-
<PAGE>   7
          confidential or proprietary within a reasonable time of its disclosure
          or which a reasonable person would expect to treat as confidential.

     5.2  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;

          (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.

     5.3  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, Reseller or the End User, as applicable.

6.   INTELLECTUAL PROPERTY RIGHTS.

     6.1  Notices. Reseller 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 Reseller.

     6.2  Reseller's Duties. Reseller will take customary measures in the
          marketing and distribution of the Products to protect SKYSTREAM's
          Intellectual Property Rights in the Products, no less than the extent
          to which Reseller protects its Intellectual Property Rights in
          Reseller's Products, and will, to the extent lawful, report promptly
          to SKYSTREAM any confirmed infringement of such rights of which
          Reseller becomes aware.

     6.3  Trademarks. Subject to the terms and conditions of this Agreement,
          SKYSTREAM grants Reseller a nonexclusive license for the term of this
          Agreement to use the Marks in Reseller's 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 Reseller
          ownership or any rights in or to use the Marks, except in accordance
          with this license, and Reseller's use of the Marks will inure to the
          benefit of SKYSTREAM. The rights granted to Reseller in this license
          will terminate upon any

                                      -7-
<PAGE>   8
          termination or expiration of this Agreement. upon such termination or
          expiration, Reseller 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; Reseller will
          neither take nor authorize any activity inconsistent with such
          exclusive right.

7.   INFRINGEMENT INDEMNITY

     7.1  Reseller Warranty.

          (a)  Reseller warrants that it owns all the rights to the
               Confidential Information provided to SKYSTREAM, and that such
               items are free of any restrictions, settlements, judgments, or
               adverse claims. Reseller warrants that it has the full power and
               authority to supply and to disclose such information to
               SKYSTREAM.

          (b)  Reseller warrants that it has not improperly or unlawfully
               acquired the information and processes submitted to SKYSTREAM.

     7.2  Reseller Indemnification. Reseller agrees to indemnify SKYSTREAM
          against, and to hold SKYSTREAM 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 7.1.

     7.3  SKYSTREAM Indemnification and Defense. Subject to the limitations
          hereinafter set forth, Reseller 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 Reseller alleging
          that the use or distribution of the Products infringes or
          misappropriates any copyright or trade secret. SKYSTREAM shall have
          sole control of any such Action or settlement negotiations, and
          SKYSTREAM agrees to pay, subject to the limitations set forth in
          Sections 7 and 8, any settlement costs or final judgment entered
          against Reseller as a result of such infringement. Reseller agrees
          that SKYSTREAM at its sole option shall be relieved of the foregoing
          obligations unless Reseller notifies SKYSTREAM promptly in writing of
          such Action and gives SKYSTREAM authority to proceed as contemplated
          herein, and, at SKYSTREAM's expense, gives SKYSTREAM proper and full
          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 intellectual property right, 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 Reseller the right to
          distribute or use, as appropriate, the Products; (ii) replace the
          Products with other suitable Products; (iii) suitably modify the
          Products; or (iv) if the foregoing


                                      -8-
<PAGE>   9
          alternatives cannot be accomplished on a commercially reasonable
          basis as determined in SKYSTREAM's sole discretion, require Reseller
          to return such Products and refund the aggregate payments paid
          therefor by Reseller, less a reasonable sum for use and damage.
          Reseller 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 Reseller to return such
          Products or arising out of any exclusions to SKYSTREAM's
          indemnification obligations set forth in Section 7.4. SKYSTREAM shall
          not be liable for any costs or expenses incurred without its prior
          written authorization.

     7.4  SKYSTREAM limitations.

          (a)  Notwithstanding the provisions of Section 7.3 above, SKYSTREAM
               assumes no liability for (i) any infringement claims (including
               without limitation combination or process patents) arising out of
               the combination of a Product or use with any 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) the modification of the Products, or any part
               thereof, unless such modification was made by SKYSTREAM; or (iii)

<PAGE>   11
     9.4  Nonexclusive Remedy. The exercise by either party of any remedy under

          this Agreement or otherwise.

     9.5  Survival. The rights and obligations of the parties contained in

          (Termination) and 10 (General) will survive the termination or
          expiration of this Agreement.

10.  GENERAL

     10.1 Publicity. Reseller agrees to use best efforts in the preparation of
          a press release announcing the execution of this Agreement, [*]

     10.2 Binding Effect. This Agreement will bind and inure to the benefit of
          each party's permitted successors and assigns.

     10.3 Governing Law. This Agreement will be governed by and 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 county of
          Santa Clara in accordance with the complex commercial litigation rules
          of the American Arbitration Association. 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 injunctive relief from any
          court in California with jurisdiction without breaching this Section
          10.3 or otherwise abridging the authority of the arbitrator.

     10.4 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.

     10.5 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

                                      -11-
<PAGE>   12
     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.

10.6 Notices. All notices under this Agreement will be deemed given when
     delivered personally, 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.

10.7 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.

10.8 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.

10.9 Entire Agreement. This Agreement and its exhibits (A, B and C) 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.

                             SKYSTREAM CORPORATION

                          TERMS AND CONDITIONS OF SALE


1.    Applicability of Terms and Conditions of Sale

      THE FOLLOWING TERMS AND CONDITIONS OF SALE ("AGREEMENT") APPLY TO ALL
      QUOTATIONS FOR PRODUCTS ("PRODUCTS") ISSUED BY SKYSTREAM CORPORATION
      ("SKYSTREAM") TO BUYER, SKYSTREAM'S ACCEPTANCE OF ANY BUYER PURCHASE
      ORDER IS EXPRESSLY CONDITIONED ON BUYER'S ASSENT TO THIS AGREEMENT. NO
      TERMS OR CONDITIONS SET FORTH IN BUYER'S PURCHASE ORDER, TO WHICH NOTICE
      OF OBJECTION IS HEREBY GIVEN, OR IN ANY FUTURE CORRESPONDENCE BETWEEN
      BUYER AND SKYSTREAM SHALL ALTER OR SUPPLEMENT THIS AGREEMENT UNLESS BOTH
      PARTIES HAVE AGREED IN WRITING TO MODIFY THIS AGREEMENT. Neither
      SKYSTREAM's commencement of performance nor delivery shall be deemed or
      construed as acceptance of Buyer's additional or different terms and
      conditions.

2.    Price

      2.1   Unless otherwise stated in writing by SKYSTREAM, all prices quoted
            are in U.S. Dollars and expire 30 days after the date of a
            quotation.

      2.2   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. Buyer agrees to pay all taxes,
            fees or charge of any nature whatsoever imposed by any governmental
            authority on, or measured by, the transaction between Buyer and
            SKYSTREAM, in addition to the prices quoted or invoiced. In the
            event that SKYSTREAM is required to collect the foregoing, such
            amounts will appear as separate items on SKYSTREAM's invoice. Buyer
            agrees to provide SKYSTREAM with a valid resale certificate for the
            Products purchased for resale.

      2.3   Notwithstanding anything to the contrary herein, in the event a
            quotation is issued pursuant to a current written purchase agreement
            between SKYSTREAM and Buyer, the quotation shall remain valid for
            the period specified or until the expiration date of the ordering
            period of any such purchase agreement, whichever occurs first.

<PAGE>   17
3.   Payment Terms

     3.1  All invoices are payable thirty (30) days from date of invoice. No
          discounts are authorized. Interest on late payments shall accrue at
          the rate of one and one half percent (1.5%) per month or the highest
          legal rate, whichever is lower. SKYSTREAM may at any time require
          that shipments be made on a C.O.D. or cash-with-order basis.

     3.2  Until the purchase price and all other charges payable to SKYSTREAM
          hereunder have been received in full, SKYSTREAM hereby retains, and
          Buyer hereby grants to SKYSTREAM, a security interest in the
          Products delivered to Buyer and any proceeds therefrom. Buyer agrees
          to promptly execute all documents reasonably requested by SKYSTREAM
          to perfect and protect such security interest. In the event Buyer
          fails promptly to execute such documents, Buyer hereby appoints
          SKYSTREAM its attorney-in-fact for the sole purpose of executing such
          documents, which appointment shall be a power coupled with an
          interest and shall be irrevocable.

     3.3  Should Buyer become delinquent in the payment of any sum due
          hereunder, SKYSTREAM shall not be obligated to continue performance
          hereunder, including without limitation shipment of any previously
          accepted orders.

     3.4  Buyer warrants to SKYSTREAM that it is financially solvent on the
          date on which it places an 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 Buyer so warrants.

4.   Delivery Dates

     4.1  All shipments are subject to SKYSTREAM's availability schedule.
          SKYSTREAM will use commercially reasonable efforts to meet any
          delivery date(s) requested in Buyer's 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 Buyer are best estimates only.

     4.2  SKYSTREAM shall have the right to make partial shipments and payment
          therefore shall be made in the manner described in Section 3.1 above.

     4.3  SKYSTREAM shall have the right to make shipments at any time before
          or after the requested delivery date and payment therefore shall be
          made in the manner described in Section 3.1 above.

<PAGE>   18
5.   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 import packaging, if not set forth
     on the invoice, will be separately invoiced.

6.   Shipment & Acceptance

     6.1  F.O.B. Point.  All prices are F.O.B. (as defined in the Uniform
          Commercial Code as implemented by the state of California, U.S.A.)
          SKYSTREAM's Mountain View location unless otherwise agreed to in
          writing. Buyer will pay all transportation and insurance charges after
          delivery to the F.O.B. point. Unless otherwise indicated by SKYSTREAM,
          Buyer is obligated to obtain insurance covering damage to the goods
          being shipped.

     6.2  Method of Shipment.  Subject to this Section 6.2, SKYSTREAM will ship
          in accordance with Buyer's shipping instructions. In the absence of
          specific instructions or if Buyer's instructions are deemed
          unsuitable, SKYSTREAM reserves the right to ship by the most
          appropriate method.

     6.3  Title and Risk of Loss.  Title to the Products and risk of loss and
          damage shall pass to Buyer upon delivery to the F.O.B. point.

     6.4  Acceptance. Products shall be deemed to have been accepted by Buyer
          unless Buyer provides written notice to SKYSTREAM to the contrary
          within thirty (30) days from the date of delivery to the F.O.B. point.
          Such written notice shall request a Return Material Authorization
          ("RMA") number and the terms and conditions that apply to warranty
          returns under Section 13.2 shall apply to returns under this Section
          6.4.

          require advance payment.

     7.4  If Buyer terminates individual orders in whole or in part because of
          SKYSTREAM's failure to timely deliver, Buyer's sole remedy shall be
          entitlement to cancel the undelivered quantity of any individual
          order.

     7.5  No cancellation of any purchase 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
          Buyer of such default.

8.   Software

     "Software" shall mean each software program provided by SKYSTREAM in
     machine-readable, object, printed, or interpreted form.  SKYSTREAM shall
     retain all right, title and ownership of any Software provided to Buyer or
     its end users. SKYSTREAM sells its products to Buyer only to the extent
     that such products consist of non-software items on the terms specified
     herein. Use of the terms "sell," "purchase," "purchase price" and similar
     terms are to be interpreted in accordance with this Section. Use of
     Software is governed by the provisions of the Software License, a copy of
     which Buyer has received and executed.

9.   Confidential Information

     9.1  It is understood that during the term of this Agreement, parties may
          receive Confidential Information belonging to the other party.  If any
          Confidential Disclosure Agreements have been executed, such Agreements
          are incorporated herein by reference.

     9.2  Confidential Information shall include information submitted in
          writing, and covers, but is not limited to, Software, designs,
          performance data, system bugs, and test programs.

     9.3  The parties shall protect the disclosed Confidential Information, by
          using the same degree of care, but not less than a reasonable degree
          of care, to prevent the unauthorized use, dissemination or publication
          of the Confidential Information, as the recipient party uses to
          protect its own Confidential Information of a like nature. Both
          SKYSTREAM and Buyer shall restrict the dissemination of such
          Confidential Information only to those personnel of each who require
          access thereto, in order to perform this Agreement.

     9.4  The obligation to protect the Confidential Information shall survive
          for three (3) years following the expiration or termination of this
          Agreement.

     9.5  The obligation to protect the Confidential Information shall not
          extend to information which:

          (a)  Was already lawfully known or acquired by the receiving party
               prior to the receipt from the disclosing party;

          (b)  Is or becomes generally known to the public through no wrongful
               act of the receiving party;

          (c)  Is received from a third party without similar restriction and
               without breach of these or similar conditions; or

          (d)  Is independently developed by the receiving party by personnel
               without access to the Confidential Information.

10.  Intellectual Property Warranty and Indemnity

     10.1 Buyer warrants that it owns all the rights to the information and
          processes including specifications, designs, instructions and
          Confidential Information provided to SKYSTREAM, and that such items
          are free of any restrictions, settlements, judgments, or adverse
          claims. Buyer warrants that it has the full power and authority to
          supply and to disclose such information to SKYSTREAM.


                                       7
<PAGE>   21
     10.2 Buyer warrants that it has not improperly or unlawfully acquired the
          information and processes submitted to SKYSTREAM.

     10.3 Buyer agrees to indemnify SKYSTREAM against, and to hold SKYSTREAM
          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 10.1
          or Section 10.2.

     10.4 Subject to the limitations hereinafter set forth, Buyer 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 Buyer alleging that the use or distribution of the Products in
          the United States infringes or misappropriates any copyright or trade
          secret. Notwithstanding the above, SKYSTREAM's obligations with
          respect to any claims to the object code within Products are subject
          to the Software License. SKYSTREAM shall have sole control of any such
          Action or settlement negotiations, and SKYSTREAM agrees to pay,
          subject to the limitations set forth in Section 14, any final judgment
          entered against Buyer as a result of such infringement in any such
          Action defended by SKYSTREAM. Buyer agrees that SKYSTREAM at its sole
          option shall be relieved of the foregoing obligations unless Buyer
          notifies SKYSTREAM promptly in writing of such Action and gives
          SKYSTREAM authority to proceed as contemplated herein, and, at
          SKYSTREAM's expense, gives SKYSTREAM proper and full 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 intellectual
          property right, 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 Buyer the right to distribute or use, as appropriate,
          the Products; (ii) replace the Products with other suitable Products;
          (iii) suitably modify the Products; of (iv) if the foregoing
          alternatives cannot be accomplished on a commercially reasonable basis
          as determined in SKYSTREAM's sole discretion, require Buyer to return
          such Products and refund the aggregate payments paid therefor by
          Buyer, less a reasonable sum for use and damage.  Buyer 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 Buyer to return such Products or arising out of
          any exclusions to SKYSTREAM's indemnification obligations set forth in
          Section 10.5. SKYSTREAM shall not be liable for any costs or expenses
          incurred without its prior written authorization.

<PAGE>   22
     10.5 Notwithstanding the provisions of Section 10.4 above, SKYSTREAM
          assumes no liability for (i) any infringement claims (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) the
          modification of the Product, or any part thereof, unless such
          modification was made by SKYSTREAM; or (iii) any infringement claims
          arising out of SKYSTREAM's compliance with Buyer's specifications or
          designs.

     10.6 SKYSTREAM's obligation to indemnify Buyer does not extend to any
          Action arising from a claim of infringement by the manufacture, use or
          sale of Products that conform to any technical standard adopted by an
          international organization such as the International Organization for
          Standardization, the International Electrotechnical Commission, and
          the CCITT/ITU, including, without limitation, the MPEG, JPEG and H.261
          standards.

     10.7 THE FOREGOING PROVISIONS OF THIS SECTION 10 STATE THE ENTIRE LIABILITY
          AND OBLIGATION OF SKYSTREAM AND THE EXCLUSIVE REMEDY OF BUYER AND ITS
          CUSTOMERS WITH RESPECT TO ANY ALLEGED INFRINGEMENT OF COPYRIGHTS,
          TRADEMARKS, PATENTS OR OTHER INTELLECTUAL PROPERTY RIGHTS BY THE
          PRODUCTS.

     10.8 SKYSTREAM shall have the right but, except as provided by Section
          10.4, not the obligation, to exclusively settle any claim, suit or
          proceeding brought against Buyer so far as it is based on an
          allegation that any Product or service furnished hereunder infringes a
          patent, copyright or other intellectual property right of any country.
          Buyer shall provide SKYSTREAM with prompt notice of any such claim,
          suit or proceeding.

11.  Intellectual Property Rights

     11.1 Buyer hereby grants SKYSTREAM a license under any patent required to
          enable SKYSTREAM to perform its obligations pursuant to this
          Agreement. This license shall extend for the duration of this
          Agreement.

     11.2 No provision in this Agreement shall be interpreted as a grant by
          SKYSTREAM to Buyer of a license to use SKYSTREAM's service-marks or
          trade marks.

     11.3 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.


                                       9
<PAGE>   23
12.  Termination by SKYSTREAM

     12.1 In the event of any proceedings, voluntary or involuntary, in
          bankruptcy or insolvency by or against Buyer, or in the event of the
          appointment, with or without Buyer's consent, of an assignee for the
          benefit of creditors, or of a receiver, SKYSTREAM may elect to
          immediately cancel any purchase order previously accepted by
          SKYSTREAM.

     12.2 In the event Buyer has materially breached this Agreement, including
          but not limited to failure to comply with credit terms, and has not
          cured such breach within 30 days after receiving notice thereof by
          SKYSTREAM, SKYSTREAM may immediately cancel any purchase order
          previously accepted by SKYSTREAM.

13.  Limited Warranty

     13.1 The Products are warranted against defects in material and workmanship
          for a period of ninety (90) days from the date of shipment to the
          F.O.B. point provided that the foregoing warranty shall not apply to
          defects that reasonably could have been discovered by Buyer during the
          30 day period following delivery to the F.O.B. 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 or SKYSTREAM's authorized agents. SKYSTREAM SHALL
          HAVE NO OBLIGATION UNDER THIS WARRANTY, AND MAKES NO REPRESENTATION AS
          TO PRODUCTS WHICH HAVE BEEN MODIFIED BY BUYER OR ITS CUSTOMERS. The
          foregoing warranty extends only to Buyers who are SKYSTREAM customers,
          and not Buyer's customers or other users of Buyers' Products. The
          foregoing warranty does not apply to any used or modified Products, or
          software within the Products, which is subject to the Software
          License.

     13.2 If the Product does not conform to the foregoing warranties, Buyer
          may, at its own risk and expense, return the allegedly defective
          Product directly to SKYSTREAM during the Warranty Period. In order to
          do so, Buyer 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, Buyer 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 Buyer, 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 Buyer at

                                       10
<PAGE>   24
          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 Buyer at Buyer's
          expense and risk, along with a written statement setting forth the
          basis for SKYSTREAM's conclusion that the returned Product was not
          defective, and Buyer agrees to pay SKYSTREAM's reasonable costs of
          handling and testing.

     13.3 THE REMEDIES PROVIDED HEREIN ARE BUYERS' SOLE AND EXCLUSIVE REMEDIES
          FOR BREACH OF WARRANTY BY 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.

14.  Limitation of Liability

     NEITHER SKYSTREAM NOR ITS SUPPLIERS SHALL BE LIABLE TO BUYER FOR ANY
     DAMAGES WITH RESPECT TO ANY SUBJECT MATTER OF THIS AGREEMENT UNDER ANY
     CONTRACT, NEGLIGENCE, STRICT LIABILITY OR OTHER LEGAL OR EQUITABLE THEORY
     (i) FOR ANY INCIDENTAL, CONSEQUENTIAL, SPECIAL OR INDIRECT DAMAGES OF ANY
     SORT EVEN IF SKYSTREAM OR ITS SUPPLIERS HAVE BEEN INFORMED OF THE
     POSSIBILITY OF SUCH DAMAGES; (ii) FOR COST OF PROCUREMENT OF SUBSTITUTE
     GOODS, TECHNOLOGY OR SERVICES; OR (iii) FOR LOSS OR CORRUPTION OF DATA OR
     INTERRUPTION OF USE. SKYSTREAM SHALL NOT BE LIABLE FOR ANY AMOUNTS IN
     EXCESS OF THE TOTAL AMOUNT ACTUALLY PAID TO SKYSTREAM HEREUNDER FOR THE
     PARTICULAR PRODUCTS THAT ARE SUBJECT TO A CLAIM. THESE LIMITATIONS SHALL
     APPLY NOTWITHSTANDING ANY FAILURE OF ESSENTIAL PURPOSE OF ANY LIMITED
     REMEDY. THE LIMITATION OF LIABILITY SET FORTH IN THIS SECTION SHALL NOT
     APPLY TO LIABILITY FOR DEATH OR PERSONAL INJURY TO THE EXTENT APPLICABLE
     LAW PROHIBITS SUCH LIMITATION.

15.  Import/Export

     Buyer 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

                                       11
<PAGE>   25
     requires an export license or other governmental approval without first
     obtaining such license or approval.

16.  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. Buyer agrees to not to
     use, to contractually bind its customers not to use, and to forbid all
     third parties from using the Products in such applications, and Buyer
     agrees to indemnify SKYSTREAM and to hold SKYSTREAM harmless from and
     against any liability arising out of Buyer's failure to contractually bind
     its customers in the manner previously described.

17.  Term  This Agreement will govern in perpetuity all of Buyer's purchases of
     Products.

18.  Publicity

     Buyer consents to the use of Buyer's name and purchase order data for use
     by SKYSTREAM at SKYSTREAM's discretion for the purpose of preparing press
     releases and promotional materials. Buyer agrees to use best efforts in
     assisting in the preparation of any such press releases or promotional
     materials.

19.  Miscellaneous

     19.1 Any notice required to be given hereunder shall be given in writing at
          the address of each party set forth in an attached quotation or
          purchase agreement, or to such other address as either party may
          substitute by written notice to the other.

     19.2 Any attempt by Buyer to assign or transfer any of the rights, duties,
          or obligations herein shall render such attempted assignment or
          transfer null and void.

     19.3 SKYSTREAM's failure to exercise any of its rights hereunder shall not
          constitute or be deemed a waiver or forfeiture of such rights.

     19.4 No U.S. Government Procurement Regulations shall be binding on either
          party unless specifically agreed to in writing prior to incorporation
          herein.

     19.5 Stenographic, typographical and clerical errors are subject to
          correction.

     19.6 Governing Law and Jurisdiction. This Agreement will be governed by and
          construed in accordance with the laws of the State of California
          applicable to agreements entered into, and to be performed entirely,
          within California

                                       12
<PAGE>   26
           between California residents, 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 county of Santa
           Clara in accordance with the complex commercial litigation rules of
           the American Arbitration Association. 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 injunctive relief from any
           court in California with jurisdiction without breaching this Section
           19.6 or otherwise abridging the authority of the arbitrator.

     19.7  In the event any proceeding or lawsuit is brought by either party to
           enforce its rights hereunder, the prevailing party shall be entitled
           to recover its costs, including expert witness fees and reasonable
           attorneys' fees.

     19.8  All disputes between the parties of any kind arising out of or
           related to this Agreement shall be brought within one (1) year after
           the accrual of the dispute.

     19.9  THE TERMS AND CONDITIONS SET FORTH HEREIN REPRESENT THE ENTIRE
           AGREEMENT BETWEEN SKYSTREAM AND BUYER WITH RESPECT TO THE SUBJECT
           MATTER AND BUYER AGREES THAT ALL PRIOR QUOTATIONS, INVOICES,
           NEGOTIATIONS, UNDERSTANDINGS, REPRESENTATIONS AND/OR AGREEMENTS OF
           THE PARTIES RELATING TO THE SUBJECT MATTER HEREOF, EXCLUDING THE
           SOFTWARE LICENSE, WHETHER ORAL OR WRITTEN, ARE MERGED HEREIN AND
           SUPERSEDED IN THEIR ENTIRETY. BUYER ACKNOWLEDGES THAT IT HAS NOT
           ENTERED INTO THIS AGREEMENT IN RELIANCE ON ANY WARRANTY OR
           REPRESENTATION BY ANY PERSON OR ENTITY EXCEPT FOR THE WARRANTIES AND
           REPRESENTATIONS SPECIFICALLY SET FORTH HEREIN. No change or
           modification of any of the terms or conditions herein shall be valid
           or binding on either party unless in writing and signed by an
           authorized representative of each party.

     19.10 Neither party shall be liable to the other for its failure to perform
           any of its obligations hereunder during any period in which such
           performance is delayed by circumstances beyond its reasonable control
           including, but not limited to, fire, flood, earthquake, war, embargo,
           strike, riot, inability to secure materials and transportation
           facilities, or the intervention of any governmental authority.

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, such as upgrading a data encapsulator (DBN-24) to a data
injection (DBN-25) or DUB-Simulcrypt conditional access product (DBN-26).
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.

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 at [*], 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).
Customers interested in upgrading their unit must provide SkyStream with 90 days
advance notice. ONLY SKYSUPPORT CUSTOMERS WILL HAVE ACCESS TO ANY LEVEL 3
UPGRADES.

NOTE: Level 3 Upgrades are only available on same-family products (i.e. DBN 2X
is a family of products, where 4, 5, 6, or other future product).
