     THEREFOR" to remove TBDs.

o    Modify Exhibit B to EchoStar VII Spacecraft Performance Specification

NOW THEREFORE, in consideration of the mutual covenants and conditions contained
herein, Buyer and Contractor agree to modify the Contract as follows:

Paragraph D. Option for additional CONUS Transmit Reflector and Feed System for
Spot Beams for less than or equal to ten (10) degrees from 119 degrees W.L.,
delete the text of paragraph D in its entirety and replace it with:

D.   Option for additional CONUS Transmit Reflector and Feed System for Spot
     Beams for less than or equal to ten (10) degrees from 119 degrees W. L.
     Buyer may exercise this option by providing Contractor authorization to
     proceed, at a specific orbital location, no later than forty (40) days
     after EDC. Additionally, Buyer shall have the option, exercisable in its
     discretion by providing written notice to Contractor, at any time until ten
     (10) months after EDC (or later if Buyer and Contractor mutually agree to
     an equitable adjustment, or to the deletion of testing as necessary in
     order to maintain schedule), to direct Contractor to commence integration
     and test of either the baseline antenna set or this Optional CONUS Transmit
     Reflector and Feed System for Spot Beams for installation on the
     Spacecraft, without affecting schedule. In the event Buyer desires to
     exercise this Option subsequent to the date(s) specified above, but prior
     to twenty-three (23) months following EDC, then the price for the Option
     and the Delivery schedule shall be subject to equitable adjustments. The
     Contractor shall use reasonable care to mitigate any impacts to the price
     and/or delivery schedule.

     If Buyer exercises this option, Contractor shall commence phases
     [CONFIDENTIAL INFORMATION OMITTED] below only following receipt of written
     notice from Buyer; such notice shall be provided at least thirty (30) days
     prior to the date shown in the schedule below for commencement of the
     relevant phase as adjusted for any delays, directing Contractor to commence
     that phase (Buyer recognizes that if it fails to provide written notice at
     least thirty (30) days prior to the date shown in the schedule below for
     commencement of any such phase, but subsequently elects to continue the
     extra antenna procurement effort, Contractor shall be entitled to an
     equitable adjustment). Buyer shall make payment to Contractor in the
     amounts set forth below within thirty (30) days after the option turn on
     and the commencement of each phase thereafter; provided that Contractor
     submits an invoice to Buyer no later than thirty (30) days prior to the
     applicable payment due date; provided further that if Contractor fails to
     timely submit an invoice to Buyer, then the applicable payment shall be due
     thirty (30) days after Buyer receives the relevant invoice. If Buyer does
     not direct that the procurement effort continue to the next phase, no
     further payments shall be due and Contractor shall not be obligated to
     continue with the work in this Option.

     Upon request, Contractor will provide Buyer with a schedule of work to be
     completed within the two month period following option turn on. Within
     forty five (45) days prior to the commencement date of each phase
     thereafter as adjusted for any delays, Contractor will provide Buyer with a
     schedule of work to be completed during that phase.
