     extend the License to geographical markets outside the Territory, provided
     that Wink shall have no obligation to provide any equipment to EchoStar for
     use outside the Territory, and provided that any installation, support,
     custom development, marketing, programming or other services to be
     performed by Wink for any use of the Wink Software outside the Territory
     shall be negotiated and agreed upon between the parties. Wink is
     specifically not obligated to operate the Wink Response Network (as defined
     in section 4.1 herein) or the equivalent thereof outside the Territory, or
     provide payments of any kind to EchoStar for use of the Wink Software
     outside the Territory.

1.3  "Updates" shall mean updates containing error corrections or minor
     enhancements to the Wink Software created by or for Wink, and designated
     for all of Wink's customers by a change in version number to the right of
     the decimal point. Updates do not include New Releases. "New Release" shall
     mean a major release of the Wink Software which occurs subsequent to the
     Measurement Date (as defined below), which contains significant new
     functionality and/or major enhancements, and which is designated for all of
     Wink's customers by a change in the digit or digits to the left of the
     decimal point in the version number. Wink shall provide a license to all
     Updates and New Releases at no charge to EchoStar during the term of this
     Master Agreement and EchoStar, in its sole discretion, shall have the
     option to utilize such Updates and New Releases. "New Products" shall mean
     new software developed or licensed by Wink which has different
     functionality than the Wink Software and is not required for the
     performance of Wink's obligations hereunder. Wink shall also provide
     support hereunder for all versions of the Wink Software (including all
     Updates and New Releases). Wink shall offer to EchoStar a license to all
     New Products created by Wink during the Term on terms that are as favorable
     or more favorable than the terms of any agreement Wink has entered into
     with any other United States video, audio and/or data service operator,
     including all cable and satellite video, audio and/or data service
     operators, for the provision of the New Products; provided, however, that
     in no event shall EchoStar's decision not to license any New Products have
     any impact whatsoever on the functionality of the Wink Software or
     EchoStar's rights to provide Interactive Wink Programs to EchoStar
     subscribers throughout the Term, and EchoStar shall be under no obligation
     to license or launch such New Products. If Wink decides not to make a New
     Product available to other parties, Wink agrees to offer to EchoStar an
     exclusive license to such New Products at a one-time fee equal to Wink's
     costs (on a Time and Materials basis) in developing and testing the New
     Products, which shall be documented in writing to EchoStar.

1.4  For purposes of this Master Agreement, the following definitions shall
     apply:

     (a)  equipment capable of receiving EchoStar signals shall be defined as an
          "EchoStar Receiver".

     (b)  an EchoStar Receiver which has been enabled to receive both EchoStar
          programming and Interactive Wink Programs transmitted over EchoStar's
          network, and (if, and only if, such Echostar Receiver has been made
          capable of receiving OpenTV Interactive Programs or Interactive ATVEF
          Programs) which has been made capable of capturing viewer responses to
          OpenTV Interactive Programs and/or Interactive ATVEF Programs
          (whichever is applicable), shall be referred to in this Master
          Agreement as a "Wink-enabled EchoStar Receiver"

     (c)  EchoStar subscribers which utilize at least one Wink-enabled EchoStar

       (e) EchoStar subscribers which utilize at least one ATVEF-response
           Enabled EchoStar Receiver and no Wink-enabled EchoStar Receivers to
           receive EchoStar video programming shall be referred to as "ATVEF
           Response-enabled EchoStar Subscribers".

1.5    EchoStar shall incur no costs except as may be expressly provided in this
       Master Agreement.

1.6    Contemporaneously with the execution of the Master Agreement, Wink agrees
       to issue to Echostar a warrant to purchase [*] shares of Wink Common
       Stock, as described further in Exhibit H. Wink further agrees to use
       commercially reasonable best efforts to obtain the necessary approvals in
       order to grant Echostar registration rights with respect to the shares
       issuable upon exercise of such warrants, as described further in Exhibit
       M.

2.    TERM

2.1.   The "Term" of this Master Agreement shall commence on the Effective Date
       and shall automatically terminate on the earlier of (a) [*] years
       following the first day the Interactive Wink Programs are distributed to
       and received by at least 10,000 Wink-enabled EchoStar Subscribers (the
       "Measurement Date") in accordance with the terms of this Master
       Agreement; or (b) seven and one half years after the Effective Date. The
       parties agree that EchoStar may, in its sole discretion, extend the
       Master Agreement upon the expiration of the Term for an additional three
       year period, provided that EchoStar shall provide prior written notice to
       Wink no later than sixty (60) days prior to the date of expiration of the
       Term of its intention to extend the Term. Such extension of the Term
       shall be granted on the most favorable rates, terms and conditions
       offered or made available to any United States video, audio and/or data
       service operator, including cable and satellite video, audio and/or data
       service operators. Wink agrees to give written notice to EchoStar no
       later than one hundred and twenty (120) days prior to the date of
       expiration of the Term of the rates, terms and conditions available to
       EchoStar for such extension.

3.     INTEGRATION AND DEPLOYMENT

3.1.   The parties agree to use their commercially reasonable efforts to develop
       a written final statement of work ("Final Statement of Work") and a
       written final schedule ("Final Schedule") within ninety (90) days of the
       Effective Date of this Master Agreement, and to incorporate such Final
       Statement of Work and Final Schedule into this Master Agreement as
       Exhibit E and Exhibit F, respectively. Once the Final Statement of Work
       and Final Schedule have been agreed upon in writing, neither party shall
       make any modifications to the Final Statement of Work and/or the Final
       Schedule without the other party's prior written consent. Each party
       acknowledges and agrees that changes to the Final Statement of Work or
       the Final Schedule may result in additional work and/or expense for the
       other party and may require changes to the Wink Software. In the event
       EchoStar desires changes, the parties will cooperate to make such changes
       on reasonable terms.

3.2.   Wink agrees to license the Wink Engine and the Wink Response Module to
       EchoStar on the following terms:

  (a)  Wink agrees, at no charge to EchoStar, to develop, adapt and test the
       Wink Engine and the Wink Response Module (if applicable) for all EchoStar
       Receiver families released during the Term which provide adequate
       functionality to receive Interactive Wink Programs, as such functionality
       is defined in Exhibit C, which EchoStar reasonably anticipates (but under
       no circumstances guarantees) will generate sales of at least 250,000
       units annually, and for which EchoStar requests in writing that Wink
       perform such work. These families may include, but may not be limited to,
       the families of

the Commission. Confidential treatment has been requested with respect to the
omitted portions.


Proprietary and Confidential           3


<PAGE>   4
       EchoStar Receivers which have been enabled to receive OpenTV Interactive
       Programs. The parties agree to negotiate without obligation on EchoStar's
       part, the commercial terms for Wink Engine and Wink Response Module
       adaptations for Echostar Receiver families which do not meet the 250,000
       unit minimum volume requirement. Wink further agrees that the Wink Engine
       and Wink Response Module for receivers capable of receiving OpenTV
       Interactive Programs shall be implemented as an o-code application using
       the OpenTV toolset and software libraries, unless Echostar provides
       written notice to the contrary, and that Wink's failure to implement the
       Wink Engine and Wink Response Module in this manner shall be considered a
       material breach under this Master Agreement.

  (b)  For the sake of clarification, Echostar's current intention under this
       Master Agreement is to download the Wink Engine and the Wink Response
       Module for Interactive OpenTV Programs to all Echostar receivers located
       in the Territory which have been or are enabled by Echostar to receive
       OpenTV Interactive Programs, provided that it is technically feasible to
       develop, adapt and test the Wink Engine and the Wink Response Module for
       such Echostar receivers in Echostar's sole and reasonable judgment.
       However, such download shall be subject to (i) the downloaded software
       (ie. the Wink Engine and the Wink Response Module) meeting all
       Specifications (as defined in section 3.2(d) below), as evidenced by
       testing acceptable to Echostar, (ii) Echostar's right to commence such
       download at any time within ninety (90) days following Echostar's final
       acceptance of the Wink Engine and Wink Response Module for each Echostar
       Receiver model, (iii) without limitation of any other rights of EchoStar
       hereunder to cease, disable or not commence the downloads, Echostar's
       right to cease, disable or not commence the downloads of the Wink Engine
       and the Wink Response Module if such download interferes in any way with
       the normal operation of such Echostar Receiver, causes an unusual number
       of customer service calls, or creates: any other, kind of significant
       operational or marketing issue for Echostar, in Echostar's sole and
       reasonable judgment, (iv) Echostar's right to complete such download to
       all Echostar Receivers of a certain model over a ninety (90) day period
       following the Start of Download ("Start of Download" shall be defined on
       a model by model basis as when at least 10,000 Echostar Receivers of such
       model have become Wink-enabled Echostar Receivers) for that model
       Echostar Receiver; and (y) Echostar's right to cease, disable or not
       commence the downloads of the Wink Engine and the Wink Response Module
       for any reason other than those provided under (iii) above, provided
       Echostar shall provide Wink with thirty days prior written notice of
       Echostar's reasons for ceasing, disabling or not commencing the download,
       and shall use reasonable efforts to propose ways in which Wink can
       address Echostar's concerns, if applicable in Echostar's reasonable
       judgment. In the event Wink performs a port pursuant to EchoStar's
       request under Section 3.2(a), which ported Wink Engine and/or Wink
       Response Module as integrated in the Wink-enabled EchoStar Receiver is
       finally accepted by EchoStar, and EchoStar fails to sell or distribute
       the applicable model series of the Wink-enabled EchoStar Receiver or to
       download the Wink Engine to applicable Wink-enabled Echostar Receivers
       (if such Echostar Receiver has already been distributed by Echostar),
       then, as Wink's sole remedy, Wink shall be entitled to reimbursement of
       the actual porting costs for such model series of the Wink-enabled
       EchoStar Receiver, up to an amount of $100,000.

  (c)  EchoStar agrees to provide to Wink free of charge (including all taxes
       and freight) no more than 20 Echostar Receiver units per receiver model
       to which EchoStar requests Wink to port the Licensed Engine. All other
       development and test equipment and tools (including but not limited to
       bit stream generators), and all hardware, software, documentation and
       equipment reasonably necessary for Wink to complete development and
       duplicate the EchoStar environment (collectively the "EchoStar
       Equipment") are the sole responsibility and expense of Wink and shall be
       provided and billed to Wink by Echostar at Echostar's cost plus shipping
       and handling. If a third party, such as OpenTV, must perform work to
       integrate the Wink Engine and Wink Response Module into such party's
       software, EchoStar shall use its reasonable efforts to require such third
       party to perform such work.

<PAGE>   5
       Upon completion, Wink shall deliver to EchoStar each item identified as a
       deliverable in the Statement of Work (a "Deliverable"). Accompanying the
       final Deliverable for a given Statement of Work, Wink shall include test
       criteria that will exercise critical functionality of such Deliverables.
       Test criteria will include test cases and test applications that test for
       cross-platform compatibilities and for EchoStar specific implementation
       features. Within sixty (60) days after receipt, EchoStar shall review and
       evaluate each Deliverable according to mutually agreed upon criteria, if
       applicable, and shall provide Wink with a written acceptance of the
       Deliverables or a written statement setting forth those errors to be
       corrected ("Statement of Errors"). "Specifications" means the technical
       and other specifications for the Deliverables to be developed by the
       parties under this Master Agreement as set forth in the Final Statement
       of Work. EchoStar shall not withhold acceptance of any Deliverable unless
       such Deliverable deviates from the Specifications. Wink and EchoStar
       recognize that the Deliverables will not be error-free, provided that
       such errors are not material. If EchoStar provides a Statement of Errors,
       Wink shall correct such errors, if any, as soon as practicable, and
       return a copy of the updated Deliverables to EchoStar for review and
       reevaluation. Wink shall have an obligation to validate any error which
       actually exists. The foregoing procedure shall be repeated until
       acceptance by EchoStar in its sole discretion of the Deliverables or
       EchoStar in its sole discretion ceases development and terminates this
       Master Agreement or the applicable Statement of Work. EchoStar's failure
       to accept or provide a Statement of Errors for such Deliverables within
       such sixty day period shall not be deemed an acceptance of such
       Deliverables. The parties agree that EchoStar's acceptance of any
       Deliverable containing any errors shall not relieve Wink of its
       obligation to fix such errors in accordance with the timetables set forth
       in Section 3.9, except to the extent that EchoStar's rights to such fixes
       are expressly waived in writing by EchoStar.

  (d)  At the start of application testing, and again upon EchoStar's acceptance
       of the completed Wink Engine and Wink Response Module ("Final
       Acceptance"), Wink shall deliver to EchoStar a master diskette or other
       digital storage media with all source code for all Wink Engine, Wink
       Response Module and code source files and all files necessary to create
       the final o-code modules, for use by EchoStar in accordance with the
       terms of this Master Agreement, winch diskette or media must be delivered
       in compliance with Wink's obligations under this Master Agreement. With
       the delivery, EchoStar shall receive all rights to modify, create
       derivative works of, and support and maintain the Wink Engine and the
       Wink Response Module at its sole discretion, as described further in
       section 13.4.

  (e)  Subject to the terms and conditions of this Master Agreement, effective
       upon Final Acceptance, Wink grants to EchoStar at no cost to EchoStar a
       non-exclusive right and license, to (a) modify, use, reproduce and have
       reproduced the Wink Engine and Wink Response Module adapted for EchoStar
       Receivers (the "Licensed Engine"), solely for the purpose of
       incorporating the Licensed Engine into a EchoStar Receiver and as
       necessary in the course of distribution and support of the Wink-enabled
       EchoStar Receiver and EchoStar's performance as permitted hereunder; (b)
       distribute and authorize others to distribute copies of the Licensed
       Engine solely for incorporation into a Wink-enabled EchoStar Receiver
       which was previously acquired by an Echostar Subscriber (directly or
       indirectly) from EchoStar; and (c) distribute the Wink-enabled EchoStar
       Receiver in the Territory (and outside the Territory as described in
       section 1.2 above). All such procedures, including related record
       retention and audit procedures, shall be mutually agreed in writing by
       EchoStar and Wink prior to any such distribution.

  (f)  As described further in section 13.4, EchoStar shall have the rights to
       modify, prepare derivative works of, reverse engineer, disassemble,
       decompile, or otherwise obtain access to the source code of the Licensed
       Engine, including but not limited to modifications of the o-code source
       code.

  (g)  EchoStar may exercise its distribution rights hereunder through the use
       of manufacturers of consumer electronics equipment authorized by EchoStar
       to brand and distribute the Wink-enabled EchoStar Receivers
       ("Subdistributors"); provided, that each Subdistributor must agree in
       writing, prior to obtaining any copy of the Licensed Engine from
       EchoStar, to be bound by restrictions similar to those imposed on
       EchoStar set forth in this Master Agreement. EchoStar shall promptly
       notify Wink if EchoStar has reason to believe that any of EchoStar's
       Subdistributors may not be abiding by such restrictions.

3.3.   Wink shall, at Wink's sole cost and expense (including costs and expenses
       of all taxes and freight), purchase for and on behalf of EchoStar and
       deliver to EchoStar at such location as EchoStar shall designate, all of
       the foregoing at no cost to EchoStar, all equipment (including total
       system-redundant equipment for back-up use) necessary to run the Wink
       Software and to enable EchoStar's insertion of Interactive Wink Programs,
       including Customer Service Virtual Channels pursuant to Section 3.8, into
       EchoStar's signals (the "Equipment"), with the exception that any MPEG
       encoders or related equipment (including, but not limited to,
       multiplexers and re-multiplexers) of the type generally used by EchoStar
       for broadcasting of data and all personal computers utilizing or running
       Microsoft Windows 95, Windows 98, Windows 2000 or Windows NT required to
       operate the Wink Software will be provided by EchoStar, at EchoStar's
       sole cost and expense, and such computers shall not be deemed Equipment
       hereunder. In addition, the parties agree that Wink shall be obligated to
       provide all equipment necessary for the insertion of Interactive Wink
       Programs associated with EchoStar's retransmission of broadcast network
       affiliate signals ("local-into-local") provided EchoStar agrees to pass
       such Interactive Wink Programs under,section 3.5. The parties agree
       that Wink shall. have no obligation to provide any additional equipment
       that may be required to enable storage or insertion of Interactive Wink
       Programs not provided by Wink or by a Programmer (as defined below) as
       part of such Programmer's video signal. Throughout the Term, Wink shall
       repair or replace any defective Equipment at its sole expense. All
       Equipment provided by Wink to EchoStar hereunder shall become the sole

       (a) A "Wink Response" is any EchoStar Subscriber response data generated
       by Interactive Wink Programs, Other Interactive Programs or Interactive
       ATVEF Programs and collected electronically by Wink.

       (b) A "Wink Transaction" is a Wink Response initiated by a Wink-enabled
       EchoStar Subscriber, and in which the Wink-enabled EchoStar Subscriber
       uses a Wink-enabled EchoStar Receiver to request products or services,
       whether such products and services are either provided at no charge to
       the Wink -enabled EchoStar Subscriber or require payment by the
       Wink-enabled EchoStar Subscriber, and where the fulfillment of that
       request requires the disclosure of subscriber specific information by
       such EchoStar Subscriber, such as name and address.

       (c) "Wink Revenue Transaction" are all Wink Transactions whereby Wink
       derives any revenue from any source pursuant to a EchoStar Subscriber's
       Wink Response; provided, however, Wink Revenue Transactions specifically
       do not include without limitation (i) the purchase of a subscription to a
       EchoStar service, whether video, audio, data or otherwise, (ii) the
       purchase of a EchoStar supplied pay-per-view movie or event, (iii) the

       make immediately effective) such terms to EchoStar. Notwithstanding the
       foregoing and Exhibit J, Wink acknowledges and agrees that Wink
       Transactions for any EchoStar Wink Program will be processed at no charge
       to EchoStar (for purposes of illustration only, there would be no charge
       to EchoStar in the event that a Wink-enabled EchoStar Subscriber upgrades
       his current EchoStar programming package via a Wink-enabled EchoStar
       Virtual Channel or a Wink-enabled EchoStar barker channel). EchoStar
       agrees that Wink Revenue Transactions shall be subject to Wink's rates
       for request for information responses ("RFI Response") and purchase
       responses ("Purchase Response"), as defined in Exhibit J. Wink agrees to

       EchoStar's share of Wink Revenue Transactions generated by ATVEF-response
       Enabled EchoStar Receivers shall be subject to EchoStar's written
       warranty and representation that EchoStar controls content and data
       services for such EchoStar Receivers. Wink's gross revenues (net of
       returns, cancellations and bad debt allowance [i.e., debts past due and
       not collected for one year from date of applicable transaction]) from
       Wink Revenue Transactions (including but not limited to Purchase
       Responses and RFI Responses, as defined in Exhibit J) generated by
       EchoStar Subscribers shall be referred to as "Gross Transaction Routing
       Fees." EchoStar's share of Gross Transaction Routing Fees shall be as set
       forth in Exhibit A. Once EchoStar reaches four million (4,000,000)
       Wink-enabled EchoStar Subscribers, EchoStar shall have the choice of
       being paid a share of Wink's Gross Transaction Routing Fees per Exhibit
       A, or being paid [*] percent ([*]) of Wink's Net Transaction Routing
       Fees. Wink's Net Transaction Fees shall be as set forth in Exhibit L.
       Once EchoStar notifies Wink it has reached four million (4,000,000)
       Wink-enabled EchoStar Subscribers, Wink shall prepare a report for
       EchoStar calculating the Net Transaction Fees for the four calendar
       quarters preceding the receipt of such notice. Upon receipt of this
       report, EchoStar shall have thirty (30) days to choose between being paid
       based on Gross Transaction Fees and Net Transaction Fees for the
       remainder of the Tenn. If EchoStar does not provide written notice to
       Wink within thirty (30) days of receipt of the report of it's desire to
       change from Gross Transaction Fees to Net Transaction Fees, Wink shall
       continue to pay EchoStar based on Gross Transactions Fees as defined in
       Exhibit A. The payments made by Wink to EchoStar for EchoStar's share of
       such Gross Transaction Routing Fees or Net Transaction Fees, as
       applicable, shall be defined as "Transaction Revenue Share" for purposes
       of this Master Agreement. Wink shall be solely responsible for all taxes
       and/or other similar governmental transactional charges, if any, with
       respect to all Gross Transaction Routing Fees and Net Transaction Routing
       Fees. Without limitation of any other rights of EchoStar, Wink warrants
       and represents that the terms for Echostar's Transaction Revenue Share
       (as defined in this Section 4.3 and in Exhibit A) are as favorable or
       more favorable than the corresponding terms of any agreement Wink has
       entered into with other United States video, audio and/or data service
       operators, including cable and satellite video, audio and/or data service

     listings and bill stuffers, shall be deemed approved unless Wink
     specifically gives written notice to EchoStar to the contrary. Nothing
     contained herein shall limit or restrict the right of EchoStar to use such
     names and marks (i) in connection with the exercise of its rights hereunder

     the remotes shipping with Wink-enabled EchoStar Receivers. For each remote,
     the location and size of the Wink Button shall be determined solely by
     EchoStar. EchoStar in its sole discretion may decide that manuals, or any
     other documentation describing functionality of the Licensed Engine will
     contain information on use of the Licensed Engine functionality and Wink

     become Wink-enabled EchoStar Subscribers) as of the Measurement Date, Wink
     agrees to provide EchoStar with promotional funds from Wink in the amount
     of (a) [*] and (b) an additional [*] per Wink-enabled EchoStar Subscriber
     after the first one million Wink-enabled EchoStar Subscribers (the sums

     MDF Funds"). All promotional and marketing expenses deemed eligible for
     Wink MDF Funds by EchoStar must be submitted to Wink for approval prior to
     commitment to such expenses, which approval shall not be unreasonably
     withheld. Payments of Wink MDF Funds to EchoStar shall be made monthly

               defamatory, libelous, slanderous or obscene, or violates or
               infringes any patent or copyright, trademark or other proprietary
               or intellectual property right of any third party or constitutes
               a misappropriation of any third party's trade secrets;

         (iv)  any misuse under the terms of this Master Agreement or otherwise
               by Wink or any third party, including, without limitation any
               Fulfillment Entity, of any EchoStar Subscriber information,
               including but not limited to EchoStar Subscriber credit card
               information or other personal financial data;

         (v)   any advertising and marketing of the Wink-enabled EchoStar
               Receivers by Wink;

         (vi)  the use by EchoStar of any materials, including advertising and
               promotional copy, supplied and/or approved by Wink;

         (vii) use of any logos, trademarks, service marks, trade names or other
               identifying information of EchoStar inconsistent with EchoStar's
               instructions;

         and Wink shall reimburse them for any and all legal, accounting and
         other fees, costs and expenses (collectively, "Expenses") reasonably
         incurred by any of them in connection with investigating, mitigating or
         defending any such Loss; provided, however, that the same shall not
         relieve EchoStar of its obligations under Section 8.2. If it is, or may
         be, determined by competent authority that the Wink Products or any
         part thereof infringes any patent, copyright, trade secret, trademark
         or other proprietary or intellectual property right of a third party or
         is enjoined, then Wink, at its sole expense and sole option, may: (a)
         procure for EchoStar the right under such patent, copyright, trade
         secret, trademark or other proprietary or intellectual property right
         to use, reproduce and distribute the Wink Products or such part thereof
         or such trademark as authorized in this Master Agreement, at no cost to
         EchoStar, or (b) subject to EchoStar's approval, which shall not be
         unreasonably withheld, replace the Wink Products or such part thereof
         or such trademark with other suitable software or trademark without
         material degradation in performance or functionality at no cost to
         EchoStar; or (c) subject to EchoStar's approval, which shall not be
         unreasonably withheld, modify the Wink Products or such part thereof or
         such trademark to avoid infringement without material degradation in
         performance or functionality at no cost to EchoStar. The foregoing
         shall not be in limitation of any rights of EchoStar to suspend or
         terminate its performance under this Master Agreement, or suspend or
         terminate this Master Agreement, pursuant to its terms, at law, or in
         equity, which EchoStar shall have full rights to do.

         Notwithstanding anything to the contrary contained in this Master
         Agreement (but without limitation of any other termination rights of
         EchoStar) in the event of any actual or threatened third party claim of
         infringement, as determined by EchoStar in its reasonable discretion,
         EchoStar shall have the right to discontinue distributing the
         Interactive Wink Programs and/or de-activate the Wink Engine.

8.2      EchoStar shall indemnify Wink, its officers, directors, shareholders,
         employees and agents for, and shall hold them harmless from and
         against, any and all direct Losses which are sustained or incurred by
         or asserted against any of them and which arise out of (i) any breach
         or default of any representation, warranty, obligation or duty of this
         Master Agreement by EchoStar; and (ii) EchoStar's advertising and
         marketing of the Interactive Wink Programs unless such materials are
         provided or approved by Wink, provided however that the same shall not
         relieve Wink of its obligations under Section 8.1. EchoStar shall
         reimburse Wink for any and all Expenses reasonably incurred by Wink in
         connection with investigating, mitigating or defending any such Loss.

8.3      Promptly after receipt by either party of notice of the commencement of
         any action, suit, proceeding or investigation in respect of which such
         party may make a claim for indemnification hereunder, such party will
         give written notice thereof to the other party; but the failure to so
         notify the other party will

Proprietary and Confidential       20

<PAGE>   21
not relieve the other party from any liability or obligation which the other
party may have to any indemnified person (i) otherwise than under this Master
Agreement or (ii) under this Master Agreement except to the extent of any
material prejudice to the other party resulting from such failure. If any such
action, suit, proceeding or investigation is brought against an indemnified
person, the indemnifying party shall undertake the defense and permit the
indemnified party to participate therein at the indemnified party's expense. If
Wink is the indemnifying party, Wink shall make no compromise or settlement of
any claim without the prior written consent of EchoStar. The compromise or
settlement of any such claim without EchoStar's prior written consent shall
release EchoStar from its obligations hereunder with respect to such claim or
action so settled. The indemnities contained in this Section 8 shall continue
throughout the Term and shall survive the termination of this Master Agreement.

         instrumentality (whether federal, state or local); act of terrorism;

         appropriate Protective Order (in such event the disclosing party shall
         also notify the other party as promptly as practicable and, if

         party may take further steps to protect the confidentiality of such
         information); (iv) in connection with any arbitration proceeding; (v)
         as part of the normal reporting or review procedure to a party's

         confidentiality will result in the substantial likelihood of

         have, including without limitation, the right to terminate this Master
         Agreement and seek damages or other legal or equitable relief The
         forgoing confidentiality obligations will survive termination of this

         year thereafter, both parties shall maintain accurate and complete
         documents and information, as well as books and records in accordance
         with generally accepted accounting principles and practices which, at a
         minimum, shall contain sufficient information to enable an auditor to
         verify compliance with this Master Agreement. Upon not less than 30

         breach. The exercise of any right or remedy herein provided shall be
         without prejudice to the right to exercise any other right or remedy
         provided herein, at law, or in equity.

for Wink-Enabled EchoStar Subscribers is met, at which point that next
Transaction Revenue Share shall apply for all Gross Transaction Routing Fees
thereafter, and so forth.
