               (a) Vesting. The Warrant shall vest and become fully exercisable
with respect to 10,000 Shares (up to a maximum of 60,000 Shares) for each (i)
$5,000,000 of Revenues (as defined in Paragraph 5 below) in excess of
$25,000,000 generated by the Business in each of the two (2) years following the
date hereof upon determination of Revenues for each of the twelve-month periods
contemplated by, and in accordance with, Paragraph 5 below (the "Revenue
Warrants") and (ii) $5,000,000 of Development Work (as defined in Paragraph 5
below) contracted with ViaSat or its Affiliates within two years of the date
hereof upon payment by LMGT or its Subsidiaries of an aggregate of $5,000,000
for such Development Work and upon payment of each $5,000,000 in the aggregate
thereafter for any such Development Work (the "Development Work Warrants"). Upon
the vesting of each 10,000 Shares, each of the parties hereto shall cause an
authorized representative to insert the appropriate information into the Vesting
Schedule, which is attached hereto as Schedule 4. The Shares shall be subject to
COMSAT's registration rights, as set forth in the Registration Rights Agreement.

               (b) Exercise Period. This Warrant shall be exercisable to the
extent vested, in whole or in part, at any time during the ten-year exercise

        5.     Determination of Revenues and Development Work.

               (a)    Calculation of Revenues.

               (i) For purposes of this Warrant, "Revenues" shall mean the
aggregate gross revenues attributable to or generated by the Business, including
any revenues generated or attributable to the licensing of Intellectual Property
constituting Transferred Technology, or, to the extent permitted by the License
Agreement, Licensed Technology; provided, however, that Revenues shall not
include revenues for Development Work or work on projects of ViaSat existing on
the Closing Date.




                                     - 2 -


               (ii) Promptly following each of the first and the second
anniversary of the date hereof, but in no event later than 60 days thereafter,
ViaSat shall prepare and submit to COMSAT a statement setting forth, in
reasonable detail, ViaSat's calculation of Revenue of the Business for the
preceding twelve-month period together with detailed support for such
calculation. If COMSAT disputes the correctness of the calculation of Revenue,
COMSAT shall notify ViaSat of its objections within 45 days of receipt of
ViaSat's calculations of Revenue and shall set forth, in reasonable detail, the
reasons for such objections. If COMSAT fails to deliver such notice of
objections, COMSAT shall be deemed to have accepted ViaSat's calculations.
COMSAT and ViaSat shall endeavor in good faith to resolve any disputed matters
within 20 days after COMSAT's delivery of a notice of objections. Any matters
remaining in dispute after such 20-day period shall be submitted to an
independent nationally known accounting firm selected by COMSAT and ViaSat to
resolve the disputed matters and to determine the actual amount of Revenue for
such twelve-month period. The determination of such firm in respect to the
correctness of the disputed matters shall be conclusive and binding on the
parties. The fees and expenses of such independent third party accounting firm
shall be paid one-half by COMSAT and one-half by ViaSat.

               (iii) The calculation of Revenue shall be determined in
accordance with ViaSat's historical practices and policies and in accordance
with the policies, practices and procedures set forth on Schedule 5 attached
hereto.

               (b)    Calculation of Development Work.

               (i) In the event that LMGT (or any of its Subsidiaries) and
ViaSat (or any of its Affiliates) enter into any agreement relating to complex,
satellite-based broadband development tasks to be performed by ViaSat (or any of
its Affiliates) in support of LMGT (or any of its Subsidiaries) during the
two-year period commencing on the date hereof, the parties shall, in connection
therewith, determine the aggregate amount of payments paid to ViaSat (or its
Affiliates) pursuant to such agreement. The amount of such payments shall
constitute "Development Work" for purposes of this Agreement.

               (ii) In the event that there is any dispute in the aggregate
amount of Development Work relating to any such agreement, the parties shall
submit such dispute to an independent third party accounting firm for
resolution. The determination of such firm in respect of the correctness of the
disputed matters shall be conclusive and binding on the parties. The fees and
expenses of such independent third party accounting firm shall be paid one-half
by COMSAT and one-half by ViaSat.

        6. Method of Exercise. While this Warrant remains outstanding and
exercisable in accordance with Paragraph 4 above, the Holder may exercise, in
whole or in part, the purchase rights evidenced hereby. Such exercise shall be
effected by:

               (a) the surrender of the Warrant, together with a duly executed
copy of the form of Warrant Exercise Form attached hereto, to the Secretary of
ViaSat at is principal offices; and




                                     - 3 -


               (b) the payment in cash or by certified or official bank check
payable to the order of ViaSat in an amount equal to the aggregate Exercise
Price for the number of Shares being purchased.

        7. Certificates for Shares. Upon the exercise of the purchase rights
evidenced by this Warrant, one or more certificates for the number of Shares so
purchased shall be issued as soon as practicable thereafter (with appropriate
restricted legends, if applicable), and in any event within thirty (30) days
after the delivery of the items referenced in Paragraph 6 above.

        8. Issuance of Shares. ViaSat covenants that the Shares, when issued
pursuant to the exercise of this Warrant, shall be duly and validly issued,
fully paid and nonassessable and free from all taxes, liens, and charges with
respect to the issuance thereof.

        9. Adjustment of Exercise Price and Number of Shares. The number of and
kind of securities purchasable upon exercise of this Warrant and the Exercise
Price shall be subject to adjustment from time to time as follows:

               (a) Subdivisions, Combinations and Other Issuances. If ViaSat
shall at any time prior to the expiration of this Warrant subdivide its Common
Stock, by split or otherwise, or combine its Common Stock, or issue additional
shares of its Common Stock as a dividend, the number of Shares issuable on the
exercise of this Warrant shall forthwith be proportionately increased in the
case of a subdivision or stock dividend, or proportionately decreased in the
case of a combination. Appropriate adjustments shall also be made to the
Exercise Price, but the aggregate Exercise Price for the total number of Shares
purchasable under this Warrant (as adjusted) shall remain the same. Any
adjustment under this Paragraph 9(a) shall become effective at the close of
business on the date the subdivision or combination becomes effective, or as of
the record date of such dividend, or in the event that no record date is fixed,
upon the making of such dividend.

               (b) Reclassification, Reorganization and Consolidation. In case
of any reclassification, capital reorganization, or change in the Common Stock
of ViaSat (other than as a result of a subdivision, combination, or stock
dividend provided for in Paragraph 9(a) above), then appropriate provisions
shall be made, and duly executed documents evidencing the same from ViaSat or
its successor shall be delivered to the Holder hereof, so that such Holder shall
have the right at any time prior to the expiration of this Warrant to purchase,
at a total price equal to that payable upon the exercise of this Warrant, the
kind and amount of shares of stock and other securities and property receivable
in connection with such reclassification, reorganization, or change by a holder
of the same number of shares of Common Stock as were purchasable by the Holder
hereof immediately prior to such reclassification, reorganization, or change. In
any such case appropriate provisions shall be made with respect to the rights
and interest of the Holder hereof so that the provisions hereof shall thereafter
be applicable with respect to any shares of stock of other securities and
property deliverable upon exercise hereof, and appropriate adjustments shall be
made to the Exercise Price hereunder, provided the aggregate Exercise Price
shall remain the same.

               (c) Notice to Warrant Holder of Adjustment. Whenever the number
of Shares is adjusted as herein provided, ViaSat shall cause to be mailed to the
Holder in accordance with



                                     - 4 -


the provisions of this Paragraph 9 a notice (i) stating that an event giving
rise to an adjustment hereunder has occurred, (ii) setting forth the adjusted
number of Shares and adjusted Exercise Price, if applicable, and (iii) showing
in reasonable detail the computations and the facts upon which such adjustments
are based.

        10. No Fractional Shares or Scrip. No fractional shares or scrip
representing fractional shares shall be issued upon the exercise of this
Warrant, but in lieu of such fractional shares ViaSat shall make a cash payment
therefor on the basis of the Exercise Price then in effect.

        11. Restrictions on Transfer. The Holder hereby acknowledges that
neither this Warrant nor any of the securities that may be acquired upon
exercise of this Warrant have been registered or qualified under the Securities
Act or under the securities laws of any state. The Holder acknowledges that,
upon exercise of this Warrant, the Shares to be issued upon such exercise will
be subject to a Registration Rights Agreement dated July 27, 2001 and applicable
federal and state securities (or other) laws requiring registration,
qualification or approval of governmental authorities before they may be
transferred following such exercise. The Holder agrees that the issuance of the
Shares may be deferred until the issuance or sale of such Shares shall be lawful
in all respects. The Holder acknowledges that a copy of the Registration Rights
Agreement may be obtained upon written request to the Secretary of ViaSat. The
restrictions imposed by this Paragraph 11 upon the exercise of this Warrant
shall cease and terminate as to any particular Shares (i) when such Shares shall
have been effectively registered and qualified under the Securities Act and all
applicable state securities laws and disposed of in accordance with the
registration statement covering such Shares or (ii) when, in the reasonable
opinion of counsel for ViaSat, such restrictions are no longer required in order
to insure compliance with the Securities Act and all applicable state securities
laws.

        12. Legends. Unless (i) the Shares have been registered under the
Securities Act or (ii) in the reasonable opinion of counsel for ViaSat such
legend is no longer required in order to ensure compliance with the Securities
Act and all applicable state securities laws, upon exercise of this Warrant and
the issuance of Shares hereunder, all certificates representing such Shares
shall bear on the face thereof substantially the following legend:

               "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE BEEN
        ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE
        SECURITIES ACT OF 1933, AS AMENDED. SUCH SHARES MAY NOT BE SOLD,
        TRANSFERRED OR PLEDGED IN THE ABSENCE OF SUCH REGISTRATION OR UNLESS
        SUCH SALE OR TRANSFER IS EXEMPT FROM THE REGISTRATION AND PROSPECTUS
        DELIVERY REQUIREMENTS OF SAID ACT."

        13. Stockholder Rights. Prior to the exercise of this Warrant, the
Holder hereof shall not be entitled to any rights of a stockholder with respect
to the Shares until the date of issuance of the Shares.

        14. Transfer and Assignment.





                                     - 5 -


               (a) Except as set forth in this Paragraph 14, neither this
Warrant nor any rights hereunder may be assigned, transferred, pledged or
hypothecated in any way (whether by operation of law or otherwise); except that
COMSAT may transfer this Warrant, or any portion of this Warrant, to an
Affiliate or in connection with the sale of all or substantially all of its
assets to a third party. This Warrant shall not be subject to execution,
attachment or similar process. Any attempted assignment, transfer, pledge,
hypothecation or other disposition of this Warrant contrary to the provisions of
this Warrant shall be null and void and without legal effect.

               (b) Prior to any transfer of this Warrant or any rights hereunder
(other than any transfer to an Affiliate that is directly or indirectly wholly
owned by Lockheed Martin Corporation), the Holder shall give five (5) days prior
written notice to ViaSat of such Holder's intention to effect such transfer (a
"Transfer Notice"). The Holder agrees that the Holder will not sell, transfer or
otherwise dispose of this Warrant or any rights hereunder, in whole or in part,
except pursuant to an effective registration statement under the Securities Act
or an exemption from registration hereunder. Each Warrant issued upon such
transfer shall bear the restrictive legend set forth on this Warrant, unless in
the opinion of the transferee's or the Holder's counsel delivered to ViaSat that
is reasonably satisfactory to ViaSat in connection with such transfer such
legend is not required in order to ensure compliance with the Securities Act.

               (c) Notwithstanding the foregoing provisions of this Paragraph
14, the restrictions imposed by Paragraph 11 upon the transferability of this
Warrant and the legend requirement of Paragraph 12 hereof shall terminate as to
this Warrant or the Shares (i) when and so long as such security shall have been
registered under the Securities Act and disposed of pursuant thereto or (ii)
when the Holder or holder of Shares shall have delivered to ViaSat the written
opinion of counsel to such holder reasonably satisfactory to ViaSat, stating
that such legend is not required in order to ensure compliance with the
Securities Act. Whenever the restrictions imposed by this Paragraph 14 shall
terminate as to this Warrant and the Shares, as hereinabove provided, the holder
of the certificate evidencing such security shall be entitled to receive from
ViaSat, at the expense of ViaSat, a new Warrant or a new certificate
representing such Shares, as the case may be, not bearing the applicable
restrictive legend.

               (d) The terms and provisions of this Warrant shall inure to the
benefit of, and be binding upon, ViaSat, the Holder and their respective
successors and assigns in accordance with this Paragraph 14.

        15. Lost or Destroyed Warrant. Upon receipt by ViaSat of evidence from
Holder of the loss, theft, destruction or mutilation of this Warrant, and upon
surrender and cancellation of this Warrant, if mutilated, ViaSat shall execute
and deliver a new warrant of like tenor and date. The Holder agrees with ViaSat
that this Warrant is issued, and all the rights hereunder shall be held subject
to, all of the conditions, limitations and provisions set forth herein.

                                   SCHEDULE 5

             Policies, Practices and Procedures to Determine Revenue

        Revenues are derived from the sale of communications equipment,
principally made up of the Linkway family of products, COMSAT Link Accelerators
and INTELSAT High Speed TDMA equipment and derivatives of those products.
Revenues from product sales are recognized at the time the equipment is shipped
to the customer. In addition to the sale of products, revenues are derived from
non-product sales that are comprised generally of services, such as program
management services and consulting; the sale of network control and management
systems and training in the operation of these systems. Revenues from
non-product sales are recognized monthly as those non-product services are
rendered or as may be modified in accordance with contract terms. Revenues
derived from the licensing of Intellectual Property to third parties would be
recognized at the earlier of the time at which they become due pursuant to an
existing contractual commitment or the time at which they are received by the
Business. The Business maintains a general reserve for uncollectable receivables
of $20,000. The Business, however, does not on an ongoing basis accrue for
uncollectable accounts receivable. Should a circumstance exist that would give
rise to the accrual of additional accounts receivable reserves, the Business'
established practice is to accrue for this as an expense, not as a reduction of
revenue. Revenue on contracts containing advanced payments are recognized at the
time the equipment is shipped or the non- product services are rendered. Should
a product be returned, the practice adopted by the Business would be to reduce
revenue in the period the product was returned by reversing the original
transaction.
