NOW, THEREFORE, in consideration of the foregoing premises and of the mutual
representations, warranties, covenants and agreements hereinafter contained, the
Parties hereby agree as follows:

ARTICLE I.

OPTION TERMS

Section 1.1. Grant of Option. Telesat shall have the right and option, at its
election, by written notice to Loral accompanied by payment of the Option Price
(as defined below) to cause Loral to assign to Telesat all of Loral’s rights
under the Beam Sharing Agreement and the Loral Payload Agreement, whereupon
Telesat will assume all of Loral’s obligations thereunder. This Option will
expire at the close of business on October 31, 2009 (the “Expiration Date”).

Section 1.2. Exercise Price. The “Option Price” shall equal the sum of (a) the
amounts paid by Loral pursuant to the Beam Sharing Agreement and the Loral
Payload Agreement (whether paid to ViaSat, SS/L, the launch services provider or
insurance broker) on or prior to the date Telesat exercises its option plus
(b) a premium equal to (i) $6,000,000 if the option is exercised prior to the
close of business on April 30, 2008 and (ii) $9,000,000 if the option is
exercised thereafter but prior to the Expiration Date plus $400,000 per month
for each full calendar month that elapses in 2009 (pro rata for partial months).
For avoidance of doubt, the maximum Option Price contemplated hereby (if the
Option is exercised on October 31, 2009) is $13,000,000.

Section 1.3. Failure to Exercise. In the event that the Option is not exercised
on or prior to the Expiration Date, Telesat shall, at Loral’s request, transfer
to Loral or its designee, Telesat’s license rights from the Isle of Man
Government or Mansat Limited to the 115 degree W.L. orbital position (the
“License Rights”), and assign to Loral or its designee all of Telesat’s rights
under the Cooperation Agreement related to the foregoing, whereupon Loral will
assume all of Telesat’s obligations related to the License Rights and Telesat’s
related obligations under the Cooperation Agreement (which shall for
clarification, not include the obligation under Section 1.1 of the Cooperation
Agreement).

Section 1.4. Beam Sharing Agreement and Loral Payload Agreement. Loral shall not
amend the terms of the Beam Sharing Agreement or the Loral Payload Agreement
prior to the Expiration Date without Telesat’s prior written consent, with such
consent not to be unreasonably withheld or delayed.

ARTICLE II.

PURCHASE PRICE

Section 2.1. Purchase Price of Option. For and in consideration of the grant of
the Option contemplated hereby, Telesat is entering into the Cooperation
Agreement and agrees to pay over to Loral all of the fees it receives under the
TT&C Agreement, other than the initial fee payable pursuant to Section 4.1(a)
thereof, when and as received from ViaSat or its assignee thereunder.

ARTICLE III.

TERMINATION

Section 3.1. Termination. This Agreement shall terminate automatically upon
termination of the Satellite Contract.

ARTICLE IV.

ASSIGNMENT

Section 4.1. General Assignment. This Agreement shall be binding upon and shall
inure to the benefit of the Parties hereto and their respective successors and
permitted assigns. Telesat may assign its rights and obligations hereunder
(other than its obligations under Sections 1.3 and 2.1, with respect to which
Telesat shall remain liable, notwithstanding any such assignment) to a third
party (the “Assignee”) provided that (i) the Assignee shall have a credit rating
on senior debt of B2 or better from Moody’s (or the equivalent); (ii) the
Assignee shall enter into an agreement with Loral and Telesat reasonably
satisfactory to Loral pursuant to which it expressly assumes all of the
Telesat’s other rights and obligations under this Agreement and agrees that upon
exercise of the Option, it will assume the obligations of Loral under the Beam
Sharing Agreement and the Loral Payload Agreement and, without limitation, will
thereafter act in accordance with the Cooperation Agreement ; (iii) Telesat
shall continue to perform its obligations under the Cooperation Agreement and
(iv) Telesat shall enter into an agreement with Loral, reasonably satisfactory
to Loral, confirming the foregoing. No assignment of this Agreement by Telesat
will relieve Telesat of any of its obligations under the TT&C Agreement or
vitiate any of the rights of ViaSat under the proviso to the second sentence of
Section 22.1 of the Beam Sharing Agreement.

Section 4.2. Security Interests. Either Party may assign its rights under this
Agreement without the consent of the other Party as security and otherwise grant
security interests in its rights hereunder to lenders that provide financing
(including hedging and cash management obligations) to such Party or its
affiliates, and the other Party agrees to consent to such assignment in a form
reasonably requested by the first Party and any lenders and/or investors
providing such financing.
