For the purposes of this Indenture, the term “consolidated” with respect to any Person means such Person consolidated with its Restricted Subsidiaries, and shall not include any Unrestricted Subsidiary, but the interest of such Person in an Unrestricted Subsidiary will be accounted for as an Investment.

“Indebtedness” means, with respect to any Person:

(1) the principal and premium (if any) of any indebtedness of such Person, whether or not contingent, (a) in respect of borrowed money, (b) evidenced by bonds, notes, debentures or similar instruments or letters of credit or bankers’ acceptances (or, without duplication, reimbursement agreements in respect thereof), (c) representing the deferred and unpaid purchase price of any property, except any such balance that constitutes a current account payable, trade payable or similar obligation incurred, (d) in respect of Capital Lease Obligations, or (e) representing any Hedging Obligations, if and to the extent that any of the foregoing indebtedness (other than letters of credit and Hedging Obligations) would appear as a liability on a balance sheet (excluding the footnotes thereto) of such Person prepared in accordance with GAAP;

-14-

(2) to the extent not otherwise included, any obligation of such Person to be liable for, or to pay, as obligor, guarantor or otherwise, the Indebtedness of another Person (other than by endorsement of negotiable instruments for collection in the ordinary course of business);

(3) to the extent not otherwise included, Indebtedness of another Person secured by a Lien on any asset owned by such Person (whether or not such Indebtedness is assumed by such Person); provided, however, that the amount of such Indebtedness will be the lesser of: (a) the Fair Market Value of such asset at such date of determination, and (b) the amount of such Indebtedness of such other Person; and

(4) to the extent not otherwise included, with respect to the Company and the Restricted Subsidiaries, the amount then outstanding (i.e., advanced, and received by, and available for use by, the Company or any of the Restricted Subsidiaries) under any Receivables Financing (as set forth in the books and records of the Company or any Restricted Subsidiary and confirmed by the agent, trustee or other representative of the institution or group providing such Receivables Financing);

provided, however, that notwithstanding the foregoing, Indebtedness shall be deemed not to include (1) Contingent Obligations incurred in the ordinary course of business and not in respect of borrowed money; (2) deferred or prepaid revenues; (3) purchase price holdbacks in respect of a portion of the purchase price of an asset to satisfy warranty or other unperformed obligations of the respective seller; (4) obligations to make payments to one or more insurers under satellite insurance policies in respect of premiums or the requirement to remit to such insurer(s) a portion of the future revenue generated by a satellite which has been declared a constructive total loss, in each case in accordance with the terms of the insurance policies relating thereto; or (5) any obligations to make progress or incentive payments or risk money payments under any satellite manufacturing contract or to make payments under satellite launch contracts in respect of launch services provided thereunder, in each case, to the extent not overdue by more than 90 days.

Notwithstanding anything in this Indenture, Indebtedness shall not include, and shall be calculated without giving effect to, the effects of Statement of Financial Accounting Standards No. 133 and related interpretations to the extent such effects would otherwise increase or decrease an amount of Indebtedness for any purpose under this Indenture as a result of accounting for any embedded derivatives created by the terms of such Indebtedness; and any such amounts that would have constituted Indebtedness under this Indenture but for the application of this sentence shall not be deemed an incurrence of Indebtedness under this Indenture.

“Person” means any individual, corporation, partnership, limited liability company, Joint Venture, association, joint-stock company, trust, unincorporated organization, government or any agency or political subdivision thereof or any other entity.
