(7) The Trustee will authenticate Global Notes and Definitive Registered Notes in accordance with the provisions of Section 2.02 hereof.

(8) All certifications, certificates and Opinions of Counsel required to be submitted to the Registrar pursuant to this Section 2.06 to effect a registration of transfer or exchange may be submitted by facsimile.

Section 2.07 Replacement Notes.

If any mutilated Note is surrendered to the Trustee or the Issuer and the Trustee receives evidence to its satisfaction of the destruction, loss or theft of any Note, the Issuer will issue and the Trustee, upon receipt of an Authentication Order, will authenticate a replacement Note if the Trustee’s requirements are met. If required by the Trustee or the Issuer, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Issuer to protect the Issuer, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Issuer may charge for its expenses in replacing a Note.

Every replacement Note is an additional obligation of the Issuer and will be entitled to all of the benefits of this Indenture equally and proportionately with all other Notes duly issued hereunder.

Section 2.08 Outstanding Notes.

The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section as not outstanding. Except as set forth in Section 2.09 hereof, a Note does not cease to be outstanding because the Issuer or an Affiliate of the Issuer holds the Note; however, Notes held by the Issuer or a Subsidiary of the Issuer shall not be deemed to be outstanding for purposes of Section 3.07(a) hereof.

If a Note is replaced pursuant to Section 2.07 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a protected purchaser.

If the principal amount of any Note is considered paid under Section 4.01 hereof, it ceases to be outstanding and interest on it ceases to accrue.

If the Paying Agent (other than the Issuer, a Subsidiary or an Affiliate of any thereof) holds, on a redemption date or maturity date, money sufficient to pay Notes payable on that date, then on and after that date such Notes will be deemed to be no longer outstanding and will cease to accrue interest.

Section 2.09 Treasury Notes.

In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Issuer or any Guarantor, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Issuer or any Guarantor, will be considered as though not outstanding, except that for the purposes of determining whether the Trustee will be protected in relying on any such direction, waiver or consent, only Notes that the Trustee knows are so owned will be so disregarded.

Section 2.10 Temporary Notes.

(a) Until certificates representing Notes are ready for delivery, the Issuer may prepare and the Trustee, upon receipt of an Authentication Order, will authenticate temporary Notes. Temporary Notes will be substantially in the form of certificated Notes but may have variations that the Issuer considers appropriate for temporary Notes and as may be reasonably acceptable to the Trustee. Without unreasonable delay, the Issuer will prepare and the Trustee will authenticate Definitive Registered Notes in exchange for temporary Notes.

(b) Holders of temporary Notes will be entitled to all of the benefits of this Indenture.

Section 2.11 Cancellation.

The Issuer at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent will forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee or, at the direction of the Trustee, the Registrar or the Paying Agent (other than the Issuer or a Subsidiary) and no one else will cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and will destroy canceled Notes (subject to the record retention requirement of the Exchange Act). Certification of the destruction of all canceled Notes will be delivered to the Issuer. The Issuer may not issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee for cancellation.

Section 2.12 Defaulted Interest.

If the Issuer defaults in a payment of interest on the Notes, it will pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01 hereof. The Issuer will notify the Trustee in writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The Issuer will fix or cause to be fixed each such special record date and payment date, provided that no such special record date may be less than 10 days prior to the related payment date for such defaulted interest. At least 15 days before the special record date, the Issuer (or, upon the written request of the Issuer, the Trustee in the name and at the expense of the Issuer) will deliver to the Holders in accordance with Section 12.02 hereof a notice that states the special record date, the related payment date and the amount of such interest to be paid.

Section 2.13 Further Issues.

(a) Subject to compliance with Section 4.09 hereof, the Issuer may from time to time issue further notes (the “Additional Notes”) ranking pari passu with Notes and with the same terms as to status, redemption and otherwise as such Notes (save for payment of interest accruing prior to the issue date of such Additional Notes or for the first payment of interest following the issue date of such Additional Notes). The Additional Notes will be consolidated and treated as a single class for all purposes under this Indenture, including, without limitation, waivers, amendments, redemptions, and offers to purchase.

(b) Whenever it is proposed to create and issue any Additional Notes, the Issuer shall give to the Trustee not less than 14 days’ notice in writing of its intention so to do stating the amount of Additional Notes proposed to be created and issued.

Section 2.14 CUSIP Number and ISIN Number.

The Issuer in issuing the Notes may use a “CUSIP” number and/or an “ISIN” number, and if so, such CUSIP Number and/or ISIN number shall be included in notices of redemption or purchase as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness or accuracy of the CUSIP Number and/or ISIN number printed in the notice or on the Notes, and that reliance may be placed only on the other identification numbers printed on the Notes. The Issuer will promptly notify the Trustee and each Agent of any change in the CUSIP Number and/or ISIN number.

Section 2.15 Deposit of Moneys.

Prior to 10:00 am (London time), on each Regular Interest Payment Date, the maturity date and each payment date relating to an Asset Sale Offer or a Change of Control Offer, and on the Business Day immediately following any acceleration of the Notes pursuant to Section 6.02, the Issuer shall deposit with the Principal Paying Agent in immediately available funds money (in U.S. Dollars) sufficient to make cash payments due on such Regular Interest Payment Date, maturity date, or Business Day, as the case may be. Subject to receipt of such funds by such time, the Principal Paying Agent and each Paying Agent shall remit such payment in a timely manner to the Holders on such Regular Interest Payment Date, maturity date or Business Day, as the case may be, to the Persons and in the manner set forth in paragraph 2 of the Notes.

Section 3.02 Selection of Notes to Be Redeemed or Purchased.

If less than all of the Notes are to be redeemed or purchased in an offer to purchase at any time, the Trustee shall select Notes for redemption or purchase as follows:

(1) if the Notes are listed on any securities or investment exchange, in compliance with the requirements of the principal securities or investment exchange on which the Notes are so listed; or

In the event of partial redemption, the particular Notes to be redeemed or purchased will be selected, unless otherwise provided herein, not less than 30 nor more than 60 days prior to the redemption or purchase date by the Trustee from the outstanding Notes not previously called for redemption or purchase.

The Trustee will promptly notify the Issuer in writing of the Notes selected for redemption or purchase and, in the case of any Note selected for partial redemption or purchase, the principal amount thereof to be redeemed or purchased. Notes and portions of Notes selected will be in amounts of $1,000 or whole multiples of $1,000; except that if all of the Notes of a Holder are to be redeemed or purchased, the entire outstanding amount of Notes held by such Holder, even if not a multiple of $1,000, shall be redeemed or purchased. Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption or purchase also apply to portions of Notes called for redemption or purchase.

Section 3.03 Notice of Redemption.

At least 30 days but not more than 60 days before a redemption date, the Issuer will mail or cause to be mailed, by first class mail, a notice of redemption to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of this Indenture pursuant to Articles 8 or 12 of this Indenture.

The notice will identify the Notes to be redeemed and will state:

(1) the redemption date;

(2) the redemption price;

(3) if any Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed and that, after the redemption date upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion will be issued upon cancellation of the original Note;

(4) the name and address of the Paying Agent(s) to which the Notes are to be surrendered for redemption;

(5) that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price, plus accrued and unpaid interest, if any, Additional Amounts, if any, and Additional Interest, if any;

At the Issuer’s request, the Trustee will give the notice of redemption in the Issuer’s name and at its expense; provided, however, that the Issuer has delivered to the Trustee, at least 45 days prior to the redemption date, an Officers’ Certificate requesting that the Trustee give such notice (unless such period is waived or reduced by the Trustee) and setting forth the information to be stated in such notice as provided in the preceding paragraph.

Section 3.04 Effect of Notice of Redemption.

Once notice of redemption is mailed in accordance with Section 3.03 hereof, Notes called for redemption become irrevocably due and payable on the redemption date at the redemption price. A notice of redemption may not be conditional.

Section 3.05 Deposit of Redemption or Purchase Price.

One Business Day prior to the redemption or purchase date, the Issuer will deposit with the Trustee or with the Principal Paying Agent money in US Dollars sufficient to pay the redemption or purchase price of, and accrued interest, Additional Amounts, and Additional Interest, if any, on all Notes to be redeemed or purchased on that date. The Trustee or the Principal Paying Agent will promptly return to the Issuer any money deposited with the Trustee or the Principal Paying Agent by the Issuer in excess of the amounts necessary to pay the redemption or purchase price of, and accrued interest, Additional Amounts and Additional Interest, if any, on, all Notes to be redeemed or purchased.

If the Issuer complies with the provisions of the preceding paragraph, on and after the redemption or purchase date, interest will cease to accrue on the Notes or the portions of Notes called for redemption or purchase (unless the Issuer defaults in the payment of the relevant redemption or purchase price). If a Note is redeemed or purchased on or after an interest record date but on or prior to the related Regular Interest Payment Date, then any accrued and unpaid interest shall be paid to the Person in whose name such Note was registered at the close of business on such record date. If any Note called for redemption or purchase is not so paid upon surrender for redemption or purchase because of the failure of the Issuer to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption or purchase date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01 hereof.

Section 3.06 Notes Redeemed or Purchased in Part.

Upon surrender of a Definitive Registered Note that is redeemed or purchased in part, the Issuer will issue and, upon receipt of an Authentication Order, the Trustee will authenticate for the Holder at the expense of the Issuer a new Definitive Registered Note equal in principal amount to the unredeemed or unpurchased portion of the Note surrendered.

Section 3.07 Optional Redemption.

(a) At any time prior to March 1, 2007, the Issuer may on any one or more occasions redeem up to 35% of the aggregate principal amount of Notes issued under this Indenture at a redemption price of 107.625% of the principal amount, plus accrued and unpaid interest, Additional Amounts and Additional Interest, if any, to the redemption date, with the net cash proceeds of one or more Public Equity Offerings received by the Parent Guarantor or a Restricted Subsidiary of the Parent Guarantor; provided that:

Section 3.08 Mandatory Redemption.

The Issuer is not required to make mandatory redemption or sinking fund payments with respect to the Notes.

Section 3.09 Offer to Purchase by Application of Excess Proceeds.

In the event that, pursuant to Section 4.10 hereof, the Issuer is required to commence an offer to all Holders to purchase Notes (an “Asset Sale Offer”), it will follow the procedures specified below.

Any Asset Sale Offer shall be made to all Holders and all holders of other Indebtedness that is pari passu with the Notes (or has been issued by a Finance Subsidiary of Inmarsat Group Limited and guaranteed by at least Inmarsat Group Limited and the other Guarantors on a pari passu basis) containing provisions similar to those set forth in this clause 3.09 and clause 4.10 hereof. The Asset Sale Offer will remain open for a period of at least 20 Business Days following its commencement

and not more than 30 Business Days, except to the extent that a longer period is required by applicable law (the “Offer Period”). No later than three Business Days after the termination of the Offer Period (the “Purchase Date”), the Issuer will apply all Excess Proceeds (the “Offer Amount”) to the purchase of Notes and such other pari passu Indebtedness (on a pro rata basis, if applicable) or, if less than the Offer Amount has been tendered, all Notes and other Indebtedness tendered in response to the Asset Sale Offer. Payment for any Notes so purchased will be made in the same manner as interest payments are made.

If the Purchase Date is on or after an interest record date and on or before the related Regular Interest Payment Date, any accrued and unpaid interest, Additional Amounts, and Additional Interest, if any, will be paid to the Person in whose name a Note is registered at the close of business on such record date, and no additional interest will be payable to Holders who tender Notes pursuant to the Asset Sale Offer.

Upon the commencement of an Asset Sale Offer, the Issuer will send, by first class mail, a notice to the Trustee and each of the Holders, with a copy to the Trustee. The notice will contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer. The notice, which will govern the terms of the Asset Sale Offer, will state:

(1) that the Asset Sale Offer is being made pursuant to this Section 3.09 and Section 4.10 hereof and the length of time the Asset Sale Offer will remain open;

(2) the Offer Amount, the purchase price and the Purchase Date;

(3) that any Note not tendered or accepted for payment will continue to accrue interest;

(4) that, unless the Issuer defaults in making such payment, any Note accepted for payment pursuant to the Asset Sale Offer will cease to accrue interest after the Purchase Date;

(5) that Holders electing to have a Note purchased pursuant to an Asset Sale Offer may elect to have Notes purchased in integral multiples of $1,000 only;

(6) that Holders electing to have Notes purchased pursuant to any Asset Sale Offer will be required to surrender the Note, with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer by book-entry transfer, to the Issuer, a Depositary, if appointed by the Issuer, or a Paying Agent at the address specified in the notice at least three Business Days before the Purchase Date;

(7) that Holders will be entitled to withdraw their election if the Issuer, the Depositary or the Paying Agent, as the case may be, receives, not later than the expiration of the Offer Period, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Note the Holder delivered for purchase and a statement that such Holder is withdrawing his election to have such Note purchased;

(8) that, if the aggregate principal amount of Notes and other pari passu Indebtedness surrendered by holders thereof exceeds the Offer Amount, the Issuer will select the Notes and other pari passu Indebtedness to be purchased on a pro rata basis based on the principal amount of Notes and such other pari passu Indebtedness surrendered (with such adjustments as may be deemed appropriate by the Issuer so that only Notes in denominations of $1,000, or integral multiples thereof, will be purchased); and

(9) that Holders whose Notes were purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered (or transferred by book-entry transfer).

On or before the Purchase Date, the Issuer will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Offer Amount of Notes or portions thereof tendered pursuant to the Asset Sale Offer, or if less than the Offer Amount has been tendered, all Notes tendered, and will deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating that such Notes or portions thereof were accepted for payment by the Issuer in accordance with the terms of this Section 3.09. The Issuer or the Principal Paying Agent, as the case may be, will promptly (but in any case not later than five days after the Purchase Date) mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and accepted by the Issuer for purchase, and the Issuer will promptly issue a new Note, and the Trustee, upon written request from the Issuer will authenticate and mail or deliver (or cause to be transferred by book entry) such new Note to such Holder, in a principal amount equal to any unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Issuer to the Holder thereof. The Issuer will publicly announce the results of the Asset Sale Offer on the Purchase Date.

Other than as specifically provided in this Section 3.09, any purchase pursuant to this Section 3.09 shall be made pursuant to the provisions of Sections 3.01 through 3.06 hereof.

Section 3.10 Redemption for Changes in Withholding Taxes

(a) The Issuer may, at its option, redeem all (but not less than all) of the Notes then outstanding at a redemption price of 100% of the principal amount thereof, plus accrued and unpaid interest to the date of redemption, if the Issuer has become, or would become, after taking reasonable measures, if any, available to it to avoid it, obliged to pay, on the next date on which any amount would be payable with respect to the Notes, any Additional Amounts as a result of any change in laws or treaties (including any regulations promulgated thereunder) or in any interpretation, administration or application regarding such laws, treaties or regulations, if such change is announced and becomes effective on or after the Issue Date. Notice of any such redemption must be given within 60 days of the effectiveness of any such change.

(b) For the avoidance of doubt, measures will be deemed not to be “reasonable” if they would breach any provision of Section 4.24. For the further avoidance of doubt, the Issuer shall not be entitled to redeem the Notes as a consequence of the adoption of the European Council Directive 2003/48/EC or any other Directive implementing the conclusions of the ECOFIN Council meeting of 26-27 November 2000 on the taxation of savings income or any law implementing or complying with, or introduced in order to conform to, such Directive.

unless, at the time of and after giving effect to such Restricted Payment:

(1) no Default or Event of Default has occurred and is continuing or would occur as a consequence of such Restricted Payment; and

(2) Inmarsat Group Limited would, at the time of such Restricted Payment and after giving pro forma effect thereto as if such Restricted Payment had been made at the beginning of the applicable four-quarter period, have been permitted to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in the first paragraph of Section 4.09; and

(3) such Restricted Payment, together with the aggregate amount of all other Restricted Payments made by Inmarsat Group Limited and its Restricted Subsidiaries since the Issue Date (excluding Restricted Payments permitted by clauses (2), (3), (4), (6), (7) and (8) of paragraph (b) below), is less than the sum, without duplication of:

▇▇

Group Limited or any Restricted Subsidiary and resulting from the repurchase, repayment or redemption of such Restricted Investments for cash, or from cash proceeds realized on the sale of all or part of such Investment or representing a return of capital (excluding dividends) with respect thereto; provided, however, that the foregoing net reduction shall not exceed the amount (in respect of any Person) of the Restricted Investment previously made (and treated as a Restricted Payment) by Inmarsat Group Limited or any Restricted Subsidiary in such Person; plus

(E) to the extent that any Unrestricted Subsidiary of Inmarsat Group Limited designated as such after the Issue Date is redesignated as a Restricted Subsidiary after the Issue Date, the lesser of (i) the Fair Market Value of Inmarsat Group Limited’s Investment in such Subsidiary as of the date of such redesignation or (ii) the sum of (A) such Fair Market Value as of the date on which such Subsidiary was originally designated as an Unrestricted Subsidiary after the Issue Date and (B) the amount of any subsequent Investment by Inmarsat Group Limited and its Restricted Subsidiaries in such Unrestricted Subsidiary made (and treated as a Restricted Payment) after the Issue Date and after the original date of designation; plus

(F) 50% of any dividends received in cash by Inmarsat Group Limited or a Guarantor after the Issue Date from an Unrestricted Subsidiary of Inmarsat Group Limited, to the extent that such dividends were not otherwise included in Consolidated Net Income of Inmarsat Group Limited for such period.

(b) So long as no Event of Default or Default that is not capable of cure has occurred and is continuing and no Default or Event of Default would be caused thereby, the provisions of Section 4.07(a) will not prohibit:

(1) the payment of any dividend within 60 days after the date of declaration of the dividend, if at the date of declaration the dividend payment would have complied with the provisions of this Indenture;

issued on the Issue Date or issued to such Persons following the Issue Date pursuant to any share option scheme, compensation plan, incentive scheme or similar arrangement or (B) the purchase, in the open market, at any time following the initial public offering of Inmarsat Group Limited or a Holdco of Inmarsat Group Limited, of listed ordinary shares of Inmarsat Group Limited or such Holdco to be reserved for issuance upon exercise of options issued to any current or former officer, director or employee of Inmarsat Group Limited or any Restricted Subsidiary pursuant to any share option scheme, compensation plan, incentive scheme or similar arrangement; provided that the aggregate price paid for all such repurchased, redeemed, acquired, retired or purchased Equity Interests referred to in clauses (A) and (B) may not exceed $5.0 million in any twelve-month period;

(6) the repurchase of Equity Interests deemed to occur upon the exercise of share options to the extent such Equity Interests represent a portion of the exercise price of those share options;

The Fair Market Value of any assets or securities that are required to be valued by this covenant will be determined in good faith by the Board of Directors whose resolution with respect thereto will be delivered to the Trustee. The Board of Directors’ determination must be based upon an opinion or appraisal issued by a Qualified Expert if the estimated Fair Market Value thereof exceeds $15.0 million.

(2) this Indenture, the Notes (including any Additional Notes), the Guarantees (including any Guarantee of Additional Notes), the Intercreditor Agreement and the Note Security Documents;

(4) any instrument governing Indebtedness of a Person acquired by Inmarsat Group Limited or any of its Restricted Subsidiaries, as in effect at the time of such acquisition (except to the extent such Indebtedness was incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person, or the property or assets of the

Person, so acquired; provided that, in the case of Indebtedness, such Indebtedness was permitted by the terms of this Indenture to be incurred;

(9) Liens permitted to be incurred under the provisions of Section 4.12 hereof that limit the right of the debtor to dispose of the assets subject to such Liens;

(10) any agreement or instrument relating to Senior Debt of a Restricted Subsidiary permitted to be incurred after the Issue Date under Section 4.09 if (A) the restrictions and encumbrances contained in the agreements governing such Senior Debt are either (i) no more restrictive or (ii) not materially less favorable to the Holders of the Notes and/or the Subordinated Intercompany Note Proceeds Loan, in each case, taken as a whole and determined in good faith by the Board of Directors, than the dividend and other payment restrictions contained in the Senior Credit Agreement and the Original Intercreditor Agreement, in each case, as in effect on the Issue Date and (B) either (i) the final Stated Maturity of the Senior Debt is prior to the final Stated Maturity of the Notes or (ii) such Senior Debt permits payments to be made to the Issuer (pursuant to the Subordinated Intercompany Note Proceeds Loan or otherwise) to fund the repayment of the Notes at final Stated Maturity;

(a) Inmarsat Group Limited will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur”) any Indebtedness (including Acquired Debt), and Inmarsat Group Limited will not issue any Disqualified Shares and will not permit any of its Restricted Subsidiaries to issue any preference shares; provided, however, that Inmarsat Group Limited may incur Indebtedness (including Acquired Debt) or issue Disqualified Shares and any Guarantor may incur Indebtedness, if the Fixed Charge Coverage Ratio for Inmarsat Group Limited’s most recently ended four full fiscal quarters for which internal financial

statements are available immediately preceding the date on which such additional Indebtedness is incurred or such Disqualified Shares are issued would have been no less than 2.0 to 1, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness had been incurred or Disqualified Shares had been issued, as the case may be, at the beginning of such four-quarter period.

(b) The provisions of Section 4.09(a) will not prohibit the incurrence of any of the following items of Indebtedness (collectively, “Permitted Debt”):

(1) the incurrence by Inmarsat Group Limited and any of its Restricted Subsidiaries of Indebtedness (and letters of credit and bank guarantees) under Credit Facilities in an aggregate principal amount at any one time outstanding under this clause (1) (with letters of credit and bank guarantees being deemed to have a principal amount equal to the maximum potential liability of Inmarsat Group Limited and its Restricted Subsidiaries thereunder) not to exceed $975 million less the aggregate amount of all repayments, optional or mandatory, of the principal of any term or capital expenditure Indebtedness under such Credit Facilities (other than repayments that are concurrently refunded or refinanced with additional Indebtedness under Credit Facilities) that have been made by Inmarsat Group Limited or any of its Restricted Subsidiaries since the Issue Date and less the aggregate amount of all commitment reductions with respect to any revolving credit borrowings under a Credit Facility that have been made by Inmarsat Group Limited or any of its Restricted Subsidiaries since the Issue Date (including those required pursuant to Section 4.10);

(2) the incurrence by Inmarsat Group Limited and its Restricted Subsidiaries of Indebtedness under or in the form of letters of credit, bank guarantees, short-term credit and overdraft facilities in an aggregate principal amount at any one time outstanding under this clause (2) (with letters of credit, guarantees and overdraft facilities being deemed to have a principal amount equal to the maximum potential liability of Inmarsat Group Limited and its Restricted Subsidiaries thereunder) not to exceed $12.0 million;

(3) the incurrence by Inmarsat Group Limited and its Restricted Subsidiaries of Existing Indebtedness (other than Indebtedness described in clauses (1), (2) and (4) of this Section 4.09(b));

(4) the incurrence by the Issuer and the Guarantors of Indebtedness represented by the Notes and the related Guarantees to be issued on the Issue Date and the Exchange Notes and the related Guarantees to be issued pursuant to the Registration Rights Agreement and the incurrence by Inmarsat Investments Limited of the Subordinated Intercompany Note Proceeds Loan on the Issue Date (for the avoidance of doubt, no Additional Notes may be issued in reliance on this clause (4));

(5) the incurrence by Inmarsat Group Limited or any of its Restricted Subsidiaries of Indebtedness represented by Capital Lease Obligations, mortgage financings or purchase money obligations, in each case, incurred for the purpose of financing all or any part of the purchase price or cost of design, construction, installation or improvement of property, plant or equipment used in the business of Inmarsat Group Limited or any of its Restricted Subsidiaries, whether through the direct purchase of assets or the ordinary shares of any Person owning such assets (including any Indebtedness deemed to be incurred in connection with such purchase), in an aggregate principal amount, including all Permitted Refinancing Indebtedness incurred to refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (5), not to exceed $20.0 million at any time outstanding;

(6) the incurrence by Inmarsat Group Limited or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of

which are used to refund, refinance, replace, defease or discharge Indebtedness (other than intercompany Indebtedness (provided that the Subordinated Intercompany Note Proceeds Loan may be refunded or refinanced to the extent required in connection with any permitted refinancing of the Notes) that was permitted by this Indenture to be incurred under Section 4.09(a) or clauses (3), (4) or (6) of this Section 4.09(b);

(7) the incurrence by Inmarsat Group Limited or any of its Restricted Subsidiaries of intercompany Indebtedness between or among Inmarsat Group Limited and any of its Restricted Subsidiaries; provided, however, that:

(A) if Inmarsat Group Limited or any Guarantor is the obligor on such Indebtedness and the payee is not Inmarsat Group Limited or a Guarantor, such Indebtedness must be expressly subordinated in right of payment to the prior payment in full in cash of all Obligations with respect to the Notes, in the case of the Issuer, or the Guarantees, in the case of a Guarantor; and

(B) (i) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than Inmarsat Group Limited or a Restricted Subsidiary of Inmarsat Group Limited and (ii) any sale or other transfer of any such Indebtedness to a Person that is not either Inmarsat Group Limited or a Restricted Subsidiary of Inmarsat Group Limited will be deemed, in each case, to constitute an incurrence of such Indebtedness by Inmarsat Group Limited or such Restricted Subsidiary, as the case may be, that was not permitted by this clause (7);

(8) the incurrence by Inmarsat Group Limited or any of its Restricted Subsidiaries of Hedging Obligations (i) for the purpose of fixing or hedging interest rate risk with respect to or in connection with any Indebtedness that is permitted by the terms of this Indenture to be outstanding or (ii) for the purpose of fixing or hedging currency exchange rate risk or changes in the prices of commodities and, in each case, not entered into for speculative purposes and including any such Hedging Obligations incurred in connection with the issuance of the Notes;

(9) the guarantee by Inmarsat Group Limited or any of its Restricted Subsidiaries (other than the Issuer) of Indebtedness of Inmarsat Group Limited or a Restricted Subsidiary of Inmarsat Group Limited that was permitted to be incurred by another provision of this Section 4.09; provided that if the Indebtedness being guaranteed is subordinated in right of payment to the Notes or the Guarantees thereof, then such guarantee shall be subordinated to the same extent as the Indebtedness guaranteed;

(10) the incurrence by Inmarsat Group Limited or any of its Restricted Subsidiaries of Indebtedness in respect of workers’ compensation claims, self-insurance obligations, bankers’ acceptances, performance and surety bonds in the ordinary course of business (including guarantees or indemnities related thereto);

(11) the incurrence by Inmarsat Group Limited or any of its Restricted Subsidiaries of Indebtedness arising from the honoring by a bank or other financial institution of a check, draft or similar instrument inadvertently drawn against insufficient funds, so long as such Indebtedness is covered within five Business Days;

(12) Indebtedness of Inmarsat Group Limited and its Restricted Subsidiaries consisting of advance or extended payment terms in the ordinary course of business;

(13) the incurrence by Inmarsat Group Limited after the Issue Date of Indebtedness pursuant to any Subordinated Intercompany Shareholder Funding Loan;

(14) the incurrence by Inmarsat Group Limited or any of its Restricted Subsidiaries of Indebtedness arising from agreements of Inmarsat Group Limited or a Restricted Subsidiary providing for indemnification, adjustment of purchase price or similar obligations, in each case, incurred or assumed in connection with the disposition of any business, assets or Share Capital of a Subsidiary, other than guarantees of Indebtedness of the Subsidiary disposed of, or incurred or assumed by any Person acquiring all or any portion of such business, assets or Share Capital for the purpose of financing such acquisition; provided that the maximum liability of Inmarsat Group Limited and its Restricted Subsidiaries in respect of all such Indebtedness shall at no time exceed the gross proceeds, including the Fair Market Value of non-cash proceeds (measured at the time received and without giving effect to any subsequent changes in value) actually received by Inmarsat Group Limited and its Restricted Subsidiaries in connection with such disposition;

(15) Indebtedness arising in connection with a sale and leaseback of the City Road Property that is permitted under Section 4.17; and

(16) the incurrence by Inmarsat Group Limited and any Guarantor of additional Indebtedness in an aggregate principal amount (or accreted value, as applicable) at any time outstanding, including all Permitted Refinancing Indebtedness incurred to refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (16), not to exceed $25.0 million at any time outstanding.

(c) For purposes of determining compliance with this Section 4.09, in the event that an item of proposed Indebtedness meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through (16) above, or is entitled to be incurred pursuant to Section 4.09(a), Inmarsat Group Limited will be permitted to classify such item of Indebtedness on the date of its incurrence in any manner that complies with this Section 4.09. Indebtedness under Credit Facilities outstanding on the Issue Date will initially be deemed to have been incurred on such date in reliance on the exception provided by clause (1) of the definition of Permitted Debt. The accrual of interest, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, and the payment of dividends on Disqualified Shares in the form of additional shares of the same class of Disqualified Shares will not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Shares for purposes of this Section 4.09; provided, in each such case, that the amount thereof is included in Fixed Charges of Inmarsat Group Limited as accrued. Notwithstanding any other provision of this Section 4.09, the maximum amount of Indebtedness that Inmarsat Group Limited or any Restricted Subsidiary may incur pursuant to this Section 4.09 shall not be deemed to be exceeded solely as a result of fluctuations in exchange rates or currency values.

(d) The amount of any Indebtedness outstanding as of any date shall be:

(1) the accreted value of the Indebtedness, in the case of any Indebtedness issued with original issue discount;

(2) in respect of Indebtedness of another Person secured by a Lien on the assets of the specified Person, the lesser of:

(a) the Fair Market Value of such asset at the date of determination, and

(b) the amount of the Indebtedness of the other Person;

(3) the greater of the liquidation preference or the maximum fixed redemption or repurchase price of the Disqualified Shares, in the case of Disqualified Shares;

(4) the Attributable Debt related thereto, in the case of any lease that is part of a sale and leaseback transaction; and

(5) the principal amount of the Indebtedness, in the case of any other Indebtedness.

(e) For purposes of the foregoing, the “maximum fixed repurchase price” of any Disqualified Shares that do not have a fixed redemption or repurchase price shall be calculated in accordance with the terms of such Disqualified Shares as if such Disqualified Shares were redeemed or repurchased on the relevant date of determination.

Section 4.10 Asset Sales and Events of Loss.

(a) Inmarsat Group Limited will not, and will not permit any of Inmarsat Group Limited’s Restricted Subsidiaries to, consummate an Asset Sale unless:

(1) Inmarsat Group Limited (or the Restricted Subsidiary, as the case may be) receives consideration at the time of the Asset Sale at least equal to the Fair Market Value of the assets or Equity Interests issued or sold or otherwise disposed of; and

(2) at least 75% of the consideration received in the Asset Sale by Inmarsat Group Limited or such Restricted Subsidiary is in the form of cash or Cash Equivalents. For purposes of this provision, each of the following will be deemed to be cash:

(A) any liabilities, as shown on the most recent consolidated balance sheet, of Inmarsat Group Limited or any Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes, any Guarantee or the Subordinated Intercompany Note Proceeds Loan) that are assumed by the transferee of any such assets pursuant to a customary novation agreement that releases Inmarsat Group Limited or such Restricted Subsidiary from liability in respect of those liabilities;

(B) any securities, notes or other obligations received by Inmarsat Group Limited or any such Restricted Subsidiary from such transferee that are converted by Inmarsat Group Limited or such Restricted Subsidiary into cash or Cash Equivalents within 60 days, to the extent of the cash or Cash Equivalents received in that conversion; and

(C) any shares or assets of the kind referred to in clauses (3), (4) or (5) of the next paragraph of this Section 4.10.

(b) Within 365 days after the receipt of any Net Proceeds from an Asset Sale and/or any Event of Loss Proceeds required pursuant to Section 4.21 to be applied as set out in this paragraph, Inmarsat Group Limited (or the applicable Restricted Subsidiary, as the case may be) may apply those Net Proceeds and Event of Loss Proceeds, at its option:

(1) to repay Indebtedness under the Senior Credit Agreement and, if that Indebtedness is revolving credit Indebtedness, to correspondingly reduce commitments with respect thereto;

(2) to repay Senior Debt and, if the Senior Debt repaid is revolving credit Indebtedness, to correspondingly reduce commitments with respect thereto;

(3) to acquire all or substantially all of the assets of, or any Share Capital of, a Permitted Business if, after giving effect to any such acquisition of Share Capital, the Permitted Business is or becomes a Restricted Subsidiary of Inmarsat Group Limited;

(4) to make a capital expenditure; or

(5) to acquire other assets that are not classified as current assets under GAAP and that are used or useful in a Permitted Business.

(c) Pending the final application of any Net Proceeds or Event of Loss Proceeds, Inmarsat Group Limited may temporarily reduce revolving credit borrowings or otherwise invest the Net Proceeds or Event of Loss Proceeds in any manner that is not prohibited by this Indenture.

(d) Any Net Proceeds from Asset Sales and Event of Loss Proceeds that are not applied or invested as provided in the preceding paragraph will constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $15.0 million, Inmarsat Group Limited will make an Asset Sale Offer to all Holders of Notes and all holders of other Indebtedness that is pari passu with the Notes (or has been issued by a Finance Subsidiary of Inmarsat Group Limited and guaranteed by at least Inmarsat Group Limited and the other Guarantors on a pari passu basis) containing provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets in accordance with Section 3.09 hereof to purchase the maximum principal amount of Notes and such other pari passu Indebtedness that may be purchased out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of principal amount plus accrued and unpaid interest and Additional Amounts, if any, and Additional Interest, if any, to the date of purchase, and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, Inmarsat Group Limited and its Restricted Subsidiaries may use those Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of Notes and other pari passu Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee shall select the Notes and such other pari passu Indebtedness to be purchased on a pro rata basis. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.

(e) Inmarsat Group Limited will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations and stock exchange rules, to the extent those laws, regulations and rules are applicable in connection with each repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations or securities or investment exchange rules conflict with Section 3.09 or this Section 4.10, Inmarsat Group Limited will comply with the applicable laws, regulations and rules and will not be deemed to have breached its obligations under Section 3.09 or this Section 4.10 by virtue of such conflict.

Section 4.11 Transactions with Affiliates.

(a) Inmarsat Group Limited will not, and will not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate of Inmarsat Group Limited (each, an “Affiliate Transaction”), unless:

(a) Inmarsat Group Limited or any other Guarantor may, directly or indirectly, create, incur, assume or suffer to exist any Lien:

Section 4.13 Business Activities.

Inmarsat Group Limited will not, and will not permit any of its Restricted Subsidiaries to, engage in any business other than a Permitted Business, except to such extent as would not be material to Inmarsat Group Limited and its Restricted Subsidiaries, taken as a whole.

Section 4.14 Corporate Existence.

Subject to Article 5 hereof, Inmarsat Group Limited shall do or cause to be done all things necessary to preserve and keep in full force and effect:

(1) its corporate existence, and the corporate, partnership or other existence of each of its Restricted Subsidiaries, in accordance with the respective organizational documents (as the same may be amended from time to time) of Inmarsat Group Limited or any such Restricted Subsidiary; and

(2) the rights (charter and statutory), licenses and franchises of Inmarsat Group Limited and its Restricted Subsidiaries;

provided, however, that Inmarsat Group Limited shall not be required to preserve any such right, license or franchise, or the corporate, partnership or other existence of any of its Restricted Subsidiaries, if the Board of Directors shall determine that the preservation thereof is no longer desirable in the conduct of the business of Inmarsat Group Limited and its Restricted Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any material respect to the Holders of the Notes.

Section 4.15 Offer to Repurchase Upon Change of Control.

(a) Upon the occurrence of a Change of Control, the Issuer shall make an offer (a “Change of Control Offer”) to each Holder to repurchase all or any part (equal to $1,000 or an integral multiple of $1,000) of each Holder’s Notes at a purchase price equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest and Additional Amounts, if any, and Additional Interest, if any, on the Notes repurchased, if any, to the date of purchase, subject to the rights of Holders of Notes on the relevant record date to receive interest due on the relevant Regular Interest Payment Date (the “Change of Control Payment”). Within ten Business Days following any Change of Control, the Issuer shall mail a notice to the Trustee and each Holder describing the transaction or transactions that constitute the Change of Control and stating:

(1) that the Change of Control Offer is being made pursuant to this Section 4.15 and that all Notes tendered will be accepted for payment;

(2) the purchase price and the purchase date, which shall be no earlier than 30 days and no later than 60 days from the date such notice is mailed (the “Change of Control Payment Date”);

(3) that any Note not tendered will continue to accrue interest;

(4) that, unless the Issuer defaults in the payment of the Change of Control Payment, all Notes accepted for payment pursuant to the Change of Control Offer will cease to accrue interest after the Change of Control Payment Date;

(5) that Holders electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender the Notes, with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer by book-entry transfer, to the Paying Agent at the address specified in the notice prior to the close of business on the third Business Day preceding the Change of Control Payment Date;

(6) that Holders will be entitled to withdraw their election if the Paying Agent receives, not later than the close of business on the Business Day preceding the Change of Control Payment Date, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of Notes delivered for purchase, and a statement that such Holder is withdrawing his election to have the Notes purchased; and

(7) that Holders whose Notes are being purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to $1,000 in principal amount or an integral multiple thereof.

The Issuer shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations and stock exchange rules to the extent those laws, regulations and rules are applicable in connection with the repurchase of the Notes as a result of a Change of

Control. To the extent that the provisions of any securities laws or regulations or stock exchange rules conflict with the provisions of Section 3.09 or this Section 4.15 of this Indenture, the Issuer shall comply with the applicable laws, regulations and rules, and shall not be deemed to have breached its obligations under Section 3.09 or this Section 4.15 by virtue of such compliance.

(b) On the Change of Control Payment Date, the Issuer shall, to the extent lawful:

(1) accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer;

(2) deposit with the Principal Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly tendered; and

(3) deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Issuer.

The Principal Paying Agent shall promptly mail to each Holder of Notes properly tendered the Change of Control Payment for such Notes, in respect of Global Notes, make such notations thereon as are necessary to reflect the Notes (or interests therein) purchased in such Change of Control Offer and, in respect of Definitive Registered Notes, cause to be authenticated and mailed to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided that each new note shall be in a principal amount of $1,000 or an integral multiple of $1,000. The Issuer shall publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

(c) Notwithstanding anything to the contrary in this Section 4.15, the Issuer will not be required to make a Change of Control Offer upon a Change of Control if (1) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 4.15 and Section 3.09 hereof and purchases all Notes properly tendered and not withdrawn under the Change of Control Offer, or (2) notice of redemption has been given pursuant to Section 3.07 hereof, unless and until there is a default in payment of the applicable redemption price.

Section 4.16 No Layering of Debt.

Inmarsat Group Limited shall not incur any Indebtedness (including Permitted Debt) that is contractually subordinated in right of payment to any other Indebtedness of Inmarsat Group Limited unless such Indebtedness is also contractually subordinated in right of payment to Inmarsat Group Limited’s Guarantee of the Notes on substantially identical terms; provided, however, that no Indebtedness will be deemed contractually subordinated in right of payment to any other Indebtedness of Inmarsat Group Limited solely by virtue of being unsecured.

No Subsidiary Guarantor shall incur any Indebtedness that is contractually subordinated in right of payment to the Senior Debt of such Guarantor and senior in right of payment to such Subsidiary Guarantor’s Guarantee; provided, however, that no Indebtedness will be deemed contractually subordinated in right of payment to any other Indebtedness of the relevant Subsidiary Guarantor solely by virtue of being unsecured.

Neither Inmarsat Group Limited nor any Guarantor shall incur any Indebtedness (in the case of Inmarsat Group Limited) or any Senior Debt (in the case of the Guarantors), in each case, if any such Indebtedness is secured by a Lien with respect to any asset and such Lien is subordinated or junior to any other Lien with respect to such asset.

Section 4.17 Limitation on Sale and Leaseback Transactions.

Inmarsat Group Limited shall not, and shall not permit any of its Restricted Subsidiaries to, enter into any sale and leaseback transaction; provided that Inmarsat Investments Limited or any other Subsidiary Guarantor may enter into a sale and leaseback transaction if:

(1) Inmarsat Investments Limited or that Subsidiary Guarantor, as applicable, could have (a) incurred Indebtedness in an amount equal to the Attributable Debt relating to such sale and leaseback transaction under the Fixed Charge Coverage Ratio test in Section 4.09(a) hereof and (b) incurred a Lien to secure such Indebtedness pursuant to the provisions of Section 4.12 hereof;

(2) the gross cash proceeds of that sale and leaseback transaction are at least equal to the Fair Market Value of the property that is the subject of that sale and leaseback transaction; and

(3) the transfer of assets in that sale and leaseback transaction is permitted by, and Inmarsat Group Limited applies the net proceeds of such transaction in compliance with, Section 4.10 hereof.

Notwithstanding the foregoing, a sale and leaseback transaction involving the City Road Property undertaken in compliance with the Senior Credit Agreement, as in effect on the Issue Date, shall not be subject to this Section 4.17.

Section 4.18 Payments for Consent.

Inmarsat Group Limited shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, pay or cause to be paid any consideration to or for the benefit of any Holder of Notes for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Notes unless such consideration is offered to be paid and is paid to all Holders of the Notes that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or agreement.

Section 4.19 Additional Subsidiary Guarantees.

(a) If:

(1) any Restricted Subsidiary of Inmarsat Group Limited that is a Material Subsidiary guarantees any Indebtedness of Inmarsat Group Limited or any Guarantor after the Issue Date or

(2) any Restricted Subsidiary in existence on the Issue Date that guarantees the Senior Credit Agreement but is not a Guarantor on the Issue Date becomes a Material Subsidiary,

then concurrently therewith, the relevant Restricted Subsidiary will jointly and severally guarantee the Notes pursuant to a supplemental indenture in the form set forth in Exhibit F; provided that (i) a Restricted Subsidiary’s Guarantee may be limited to the extent required by law (but, in such a case, each of Inmarsat Group Limited and its Restricted Subsidiaries will use their best efforts to overcome the relevant legal limit precluding the giving of a joint and several Guarantee and, in the case of a financial assistance or similar prohibition, will procure that the relevant Restricted Subsidiary undertakes all whitewash or similar procedures which are legally permitted) and (ii) for so long as it is not permissible under applicable law for a Restricted Subsidiary to become a Guarantor, such Restricted Subsidiary need not become a Guarantor (but, in such a case, each of Inmarsat Group Limited and its Restricted Subsidiaries will use their best efforts to overcome the relevant legal

prohibition precluding the giving of the Guarantee and, in the case of a financial assistance or similar prohibition, will procure that the relevant Restricted Subsidiary undertakes all whitewash or similar procedures which are legally permitted).

(b) At the time of execution of the supplemental indenture, Inmarsat Investments Limited shall deliver an Opinion of Counsel addressed to and reasonably satisfactory to the Trustee to the effect that such supplemental indenture has been duly authorized, executed and delivered by the relevant Restricted Subsidiary and constitutes a valid and binding agreement of that Restricted Subsidiary, enforceable in accordance with its terms (subject to customary exceptions).

(c) In the case of clause (a)(1) above, if the Indebtedness of Inmarsat Group Limited or the Guarantor giving rise to the need to guarantee the Notes:

(1) ranks pari passu in right of payment to the Guarantees, any guarantee of such Indebtedness shall rank pari passu in right of payment to the relevant Guarantee of the Notes; or

(2) is contractually subordinated in right of payment to the Guarantees of the Notes, any guarantee of such Indebtedness shall be contractually subordinated in right of payment to the Guarantee of the Notes substantially to the same extent as such Indebtedness is subordinated in right of payment to the Guarantees.

(d) In the case of clause (a)(2) above, the relevant guarantee shall be subordinated in right of payment to the guarantee under the Senior Credit Agreement to the same extent as the existing Guarantees under this Indenture.

Until all amounts which may be or become payable by the Issuer and the Guarantors under the Notes have been irrevocably paid in full in cash, to the extent lawful each such Guarantee shall provide that the Guarantor waives and will not in any manner whatsoever claim or take the benefit or advantage of, any rights of reimbursement, indemnity or subrogation or any other rights against the Issuer, Inmarsat Group Limited or any Restricted Subsidiary of Inmarsat Group Limited as a result of any payment by such Guarantor under its Guarantee.

Each such Guarantee will mature, will be subordinated in right of payment and will be released under the circumstances set out in Article 11.

Section 4.20 Designation of Restricted and Unrestricted Subsidiaries.

The Board of Directors of Inmarsat Group Limited may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if that designation would not cause a Default; provided that in no event shall the business currently operated by any of the Issuer, Inmarsat Investments Limited, Inmarsat Ventures Limited, Inmarsat Ltd (UK), Inmarsat Leasing (Two) Ltd and Inmarsat Launch Company Limited be transferred to or held by an Unrestricted Subsidiary. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned by Inmarsat Group Limited and its Restricted Subsidiaries in the Subsidiary designated as Unrestricted will be deemed to be an Investment made as of the time of the designation and will reduce the amount available for Restricted Payments under Section 4.07 hereof or under one or more clauses of the definition of Permitted Investments, as determined by Inmarsat Group Limited. That designation will only be permitted if the Investment would be permitted at that time and if the Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. The Board of Directors of Inmarsat Group Limited may redesignate any Unrestricted Subsidiary to be a Restricted Subsidiary if that redesignation would not cause a Default.

Any designation of a Subsidiary of Inmarsat Group Limited as an Unrestricted Subsidiary will be evidenced to the Trustee by filing with the Trustee on the effective date of such designation a

certified copy of the Board Resolution giving effect to such designation and an Officers’ Certificate certifying that such designation complied with the preceding conditions and was permitted by Section 4.07 hereof. If, at any time, any Unrestricted Subsidiary would fail to meet the preceding requirements as an Unrestricted Subsidiary, it will thereafter cease to be an Unrestricted Subsidiary for purposes of this Indenture and any Indebtedness of such Subsidiary will be deemed to be incurred by a Restricted Subsidiary of Inmarsat Group Limited as of such date and, if such Indebtedness is not permitted to be incurred as of such date under Section 4.09 hereof, Inmarsat Group Limited will be in default of such covenant.

The Board of Directors of Inmarsat Group Limited may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary; provided that such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of Inmarsat Group Limited of any outstanding Indebtedness of such Unrestricted Subsidiary and such designation will only be permitted if (1) such Indebtedness is permitted under Section 4.09 hereof, calculated on a pro forma basis as if such designation had occurred at the beginning of the four-quarter reference period and (2) no Default or Event of Default would be in existence following such designation.

Section 4.21 Maintenance of Insurance.

(a) Inmarsat Group Limited and its Restricted Subsidiaries will maintain insurance on and in relation to their business and insurable assets with reputable underwriters or insurance companies as follows:

(1) against those risks, and to the extent, usually insured against by prudent companies carrying on a similar business; and

(2) against those risks, and to the extent, required by applicable law or by contract.

For purposes of clauses (1) and (2) of this Section 4.21(a), such insurance shall cover risks recommended to be covered by, and at commercially prudent levels no lower than those recommended by, the insurance brokers or advisors to Inmarsat Group Limited and its Restricted Subsidiary from time to time; provided that Inmarsat Group Limited shall not be required to implement any such recommendation if the Board of Directors has considered such recommendation and determined in good faith (acting reasonably) that there are sound commercial reasons for not implementing the relevant recommendation.

(b) In respect of the Inmarsat-2, Inmarsat-3 and Inmarsat-4 satellites of Inmarsat Group Limited and its Restricted Subsidiaries, clauses (1) and (2) of Section 4.21(a) shall be satisfied if Inmarsat Group Limited and its Restricted Subsidiaries maintain, subject to customary exclusions in the market for satellite insurance:

(1) from the Issue Date, in-orbit insurance for all Inmarsat-3 satellites on a net book value basis (or such lesser cover as can be obtained for an annual premium of $3,000,000); and

(2) from 30 days prior to the first launch of an Inmarsat-4 satellite, launch insurance in respect of three Inmarsat-4 satellites providing for (A) partial cover of not less than $100,000,000 in respect of the first loss, (B) net book value cover for all subsequent losses and (C) coverage for each such satellite through at least six months following launch; and

(3) from and after three days prior to expiration of the initial launch coverage referred to in clause (2) above in respect of any Inmarsat-4 satellite, in-orbit insurance in respect of each such satellite providing for net book value cover at all times;

provided, however, that (i) clause (1) of this Section 4.21(b) shall be satisfied on any date of determination if (A) Inmarsat Group Limited and its Restricted Subsidiaries have in orbit at least five Inmarsat-3 satellites (none of which functions in a manner that would constitute a “total loss” or has given rise to the receipt of insurance proceeds for a “total loss,” in either case, under the in-orbit insurance of Inmarsat Group Limited and its Restricted Subsidiaries) and (B) all Inmarsat-3 satellites are insured on a net book value basis, but payment under such insurance is excluded for the first loss of an Inmarsat-3 satellite and (ii) notwithstanding clause (1) of this Section 4.21(b), Inmarsat Group Limited and its Restricted Subsidiaries need not maintain in-orbit insurance for the Inmarsat-3 satellites from and after the date on which at least one Inmarsat-4 satellite has been accepted in orbit if the insurance referred to in clause (2) and (when required) clause (3) of this Section 4.21(b) is in place; and provided further, that, notwithstanding clause (3) of this Section 4.21(b), if and for so long as (A) two Inmarsat-4 satellites have been accepted in orbit and (B) a third Inmarsat-4 satellite has been constructed and is being stored as a ground spare, clause (3) of Section 4.21(b) shall be satisfied if Inmarsat Group Limited and its Restricted Subsidiaries maintain, from and after three days prior to expiration of the initial launch coverage referred to in clause (2) of this Section 4.21(b), (A) (x) partial in-orbit cover in respect of the first loss of an Inmarsat-4 satellite in an amount sufficient to cover (I) the cost of purchasing a new launch vehicle for the ground spare plus (II) the cost of insurance cover as described in clause (2)(B) of this Section 4.21(b) in respect of the launch of the ground spare, which shall in no event be less than $120.0 million and (y) business interruption insurance covering any period between the first loss of an Inmarsat-4 satellite and acceptance in orbit of the ground spare and (B) net book value cover for all other Inmarsat-4 satellite losses. For purposes of determining the amount of insurance required to satisfy the requirements of clause (x) of this paragraph, Inmarsat Investments Limited shall obtain an insurance report from its insurance broker setting out such broker’s recommendations regarding such insurance cover and levels at the time it is seeking to implement such insurance and at least once every financial year thereafter.

(c) For the purposes of clauses (b)(1) and (b)(3) of this Section 4.21, “net book value” shall be the average of the book values of the relevant satellite as of the first and last days of the period covered by the relevant insurance, in each case, determined in accordance with GAAP; provided that the relevant period covered by the relevant insurance is one year or less.

(d) Inmarsat Group Limited and its Restricted Subsidiaries shall promptly pay all premiums and do all things necessary to maintain insurance required of it pursuant to this Section 4.21.

(e) Neither Inmarsat Group Limited nor its Restricted Subsidiaries will do or omit to do anything which might render any insurance required by this Section 4.21 void, voidable or unenforceable.

(f) If (i) Inmarsat Group Limited or any Restricted Subsidiary receives proceeds from any insurance that covers a satellite owned or utilized by Inmarsat Group Limited or its Restricted Subsidiaries or (ii) Inmarsat Group Limited or any Restricted Subsidiary receives proceeds from any insurance maintained by any satellite manufacturer or any launch provider covering any of such satellites (the event resulting in the payment of such proceeds, an “Event of Loss”), then all related Event of Loss Proceeds shall be applied in the manner provided for in the second paragraph under Section 4.10.

Section 4.22 Additional Amounts.

All payments made by the Issuer and the Guarantors under or with respect to the Notes and the Guarantees will be made free and clear of and without withholding or deduction for or on account of any present or future tax, duty, levy, impost, assessment, or other governmental charge of whatever nature (including penalties, interest and other liabilities related thereto) (collectively, “Taxes”) imposed or levied by or on behalf of any government or political subdivision or territory or possession of any government or authority or agency or authority therein or thereof having the power to tax

(each, a “Taxing Authority”) in any jurisdiction in which the Issuer or any Guarantor (including their permitted successors and assigns) is then incorporated, engaged in business or resident for tax purposes or any jurisdiction by or through which payment is made (each, a “Relevant Taxing Jurisdiction”) unless the Issuer or the Guarantor is required to withhold or deduct Taxes by Law or by the relevant Taxing Authority’s interpretation or administration thereof.

If the Issuer or the Guarantor is required to withhold or deduct any amount for or on account of Taxes from any payment made under or with respect to the Notes or the Guarantees (as the case may be), the Issuer or the Guarantors (as the case may be) will pay such additional amounts (“Additional Amounts”) as may be necessary so that the net amount received by each Holder of the Notes (including Additional Amounts) after such withholding or deduction will be equal to the amount the Holder of the Notes would have received if such Taxes had not been withheld or deducted; provided that no Additional Amounts will be payable with respect to a payment made to a Holder of the Notes (an “Excluded Holder”) to the extent:

(1) any such Taxes would not have been imposed but for the existence of any present or former connection between such Holder of the Notes and the Relevant Taxing Jurisdiction imposing such Taxes otherwise than merely by the acquisition, ownership or disposition of such Note or receiving any payment in respect thereof or the exercise or enforcement of any rights under the Notes or the Guarantees; or

(2) such Holder of the Notes would not have been liable for or subject to such withholding or deduction on account of such Taxes but for the failure to make a valid declaration of non-residence or similar claim for exemption or to provide information concerning nationality, residence or connection with the Relevant Taxing Jurisdiction if:

(a) the making of such declaration or claim or provision of such information is required or imposed by statute, treaty, regulation, ruling or administrative practice of a Taxing Authority of the Relevant Taxing Jurisdiction as a pre-condition to an exemption from, or reduction in, such Taxes; and

(b) at least 60 days prior to the first payment date with respect to which the Issuer or the Guarantors shall apply this clause (2), the Issuer and the Guarantors shall have notified that Holder of the Notes in writing that they shall be required to provide such declaration, claim or information; or

(3) such Holder of the Notes would have been able to avoid such Taxes by presenting the relevant Note to another Paying Agent in a member state of the European Union (as constituted on the Issue Date) or in the United States; or

(4) any such Taxes would not have been imposed but for the presentation by the Holder of such Note (where presentation is required) for payment on a date more than 30 days after the date on which such payment became due or payable or was duly provided for, whichever is later; or

(5) where such withholding or deduction is imposed on a payment to an individual and is required to be made pursuant to European Council Directive 2003/48/EC or any other Directive implementing the conclusions of the ECOFIN Council meeting of 26-27 November 2000 on the taxation of savings income or any law implementing or complying with, or introduced in order to conform to, such Directive; or

(6) of any combination of the immediately preceding clauses (1) to (5) (inclusive).

In addition, Additional Amounts will not be payable with respect to any estate, inheritance, gift, sales, transfer, personal property or any similar tax, assessment or other governmental charge with respect to such Notes or with respect to any Tax which is payable otherwise than by deduction or withholding from payments of principal of, premium or discount, if any, or interest on the Notes.

The Issuer or the Guarantors (as the case may be) will also (1) make any required withholding or deduction; and (2) remit the full amount deducted or withheld to the relevant Taxing Authority in accordance with applicable Law.

The Issuer or the Guarantors (as the case may be) will make reasonable efforts to obtain certified copies of tax receipts evidencing the payment of any Taxes so deducted or withheld from each Taxing Authority imposing such Taxes. The Issuer or the Guarantors (as the case may be) will use reasonable efforts to furnish to the Holders of the Notes (with a copy to the Trustee), within 30 days after the date the payment of any Taxes so deducted or withheld is due pursuant to applicable Law, either certified copies of tax receipts evidencing such payment by the Issuer or the Guarantors (as the case may be) or, if such receipts are not obtainable, other evidence of such payments by the Issuer or the Guarantors (as the case may be).

At least 30 days prior to each date on which any payment under or with respect to the Notes is due and payable, if the Issuer or the Guarantors (as the case may be) will be obliged to pay Additional Amounts with respect to such payment, the Issuer or the Guarantors (as the case may be) will deliver to the Trustee and the Principal Paying Agent an Officers’ Certificate stating the fact that such Additional Amounts will be payable and the amounts so payable and will set forth such other information necessary to enable the Paying Agent on behalf of the Trustee to pay such Additional Amounts to the Holders on the payment date.

Whenever in this Indenture there is mentioned, in any context, the payment of amounts based upon the principal, premium, interest or of any other amount payable under, or with respect to, any of the Notes, such mention shall be deemed to include mention of the payment of Additional Amounts to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof.

The Issuer or the Guarantors (as the case may be) will pay any stamp, transfer, court or documentary taxes, or any other excise or property taxes, charges or similar levies which arise from the original execution, delivery or registration of the Notes, the initial resale thereof by the initial purchasers and the enforcement of the Notes, the Guarantees or the Note Security Documents following the occurrence of any Event of Default with respect to the Notes.

The foregoing provisions shall survive any termination, defeasance or discharge of the Notes and shall apply mutatis mutandis to any jurisdiction in which any successor Person to the Issuer or the Guarantor, as the case may be, is organized, engaged in business, resident for tax purposes, or otherwise subject to taxation on a net income basis or any political sub-divisions or Taxing Authority or agency thereof or therein.

Section 4.23 Listing

The Issuer will use its reasonable endeavors to obtain and maintain the listing of the Notes on the Luxembourg Stock Exchange for so long as such Notes are outstanding; provided that if at any time the Issuer determines that it can no longer reasonably comply with the requirements for listing the Notes on the Luxembourg Stock Exchange or if maintenance of such listing becomes unduly onerous, it will obtain prior to the delisting of the Notes from the Luxembourg Stock Exchange, and thereafter use its reasonable best efforts to maintain, a listing of such Notes on such other “recognized stock exchange” as defined in §841 of the Income and Corporation Taxes ▇▇▇ ▇▇▇▇ of the United Kingdom.

Section 4.24 Special Purpose Vehicle Covenants.

In the case of an Event of Default specified in clause (7) to (12) of Section 6.01 hereof, with respect to Inmarsat Group Limited or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of its Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary, all outstanding Notes will become due and payable immediately without further action or notice. If any other Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately.

Upon any such declaration, the Notes shall become due and payable immediately.

The Holders of a majority in aggregate principal amount of the then outstanding Notes by written notice to the Trustee may, on behalf of all of the Holders, rescind an acceleration or waive any existing Default or Event of Default and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default (except nonpayment of principal, interest or premium or Additional Amounts, if any, and Additional Interest, if any, that has become due solely because of the acceleration) have been cured or waived.

Section 6.03 Other Remedies.

If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal, premium and Additional Amounts, if any, and Additional Interest, if any, and interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture.

The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder of a Note in exercising any right or remedy accruing upon an Event of Default shall not impair the right or

remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law.

Section 6.04 Waiver of Past Defaults.

Holders of not less than a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may on behalf of the Holders of all of the Notes waive an existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of the principal, interest, premium, Additional Amounts and Additional Interest, if any on the Notes (including in connection with an offer to purchase); provided, however, that the Holders of a majority in aggregate principal amount of the then outstanding Notes may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.

Section 6.05 Control by Majority.

Holders of a majority in principal amount of the then outstanding Notes may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that (a) conflicts with law or this Indenture that the Trustee determines may be unduly prejudicial to the rights of other Holders of Notes or that may involve the Trustee in personal liability or (b) would result in a breach of the Trustee’s obligations under the Intercreditor Agreement.

In connection with the exercise of its functions (including but not limited to those referred to herein) the Trustee shall have regard to the interests of the Holders of the Notes as a class and shall not have regard to the consequences of such exercise for individual Holders.

Section 6.06 Limitation on Suits.

Except to enforce the right to receive payment of principal, premium (if any) or interest when due, no Holder may pursue any remedy with respect to this Indenture, the Notes or the Note Security Documents unless:

(1) such Holder has previously given the Trustee notice that an Event of Default is continuing;

(2) Holders of at least 25% in aggregate principal amount of the outstanding Notes have requested in writing the Trustee to pursue the remedy;

(3) such Holders have offered the Trustee reasonable security or indemnity against any loss, liability or expense;

(4) the Trustee has not complied with such request within 60 days after the receipt thereof and the offer of security or indemnity; and

(5) Holders of a majority in aggregate principal amount of the outstanding Notes have not given the Trustee a direction inconsistent with such request within such 60-day period.

A Holder of a Note may not use this Indenture to prejudice the rights of another Holder of a Note or to obtain a preference or priority over another Holder of a Note.

Section 6.07 Rights of Holders of Notes to Receive Payment.

Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal, premium and Additional Amounts, if any, and Additional Interest, if any, and interest on the Note, on or after the respective due dates expressed in the Note (including in connection with an offer to purchase), or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder; provided that a Holder shall not have the right to institute any such suit for the enforcement of payment if and to the extent that the institution or prosecution thereof or the entry of judgment therein would, under applicable law, result in the surrender, impairment, waiver or loss of the Lien of this Indenture upon any property subject to such Lien.

Section 6.08 Collection Suit by Trustee.

If an Event of Default specified in Section 6.01(1) or (2) occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Issuer for the whole amount of principal of, premium and Additional Amounts, if any, and Additional Interest, if any, and interest remaining unpaid on the Notes and interest on overdue principal and, to the extent lawful, interest and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

Section 6.09 Trustee May File Proofs of Claim.

The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the Issuer (or any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 6.10 Priorities.

If the Trustee collects any money pursuant to this Article 6, it shall pay out the money in the following order:

First: to the Trustee, its agents and attorneys for amounts due under Section 7.07 hereof, including payment of all compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection;

Second: to Holders of Notes for amounts due and unpaid on the Notes for principal, premium and Additional Amounts, if any, and Additional Interest, if any, and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal, premium and Additional Amounts, if any, and Additional Interest, if any, and interest, respectively; and

This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder of a Note pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in principal amount of the then outstanding Notes.

The Issuer or such Guarantor will defend the claim and the Trustee will cooperate in the defense.

ARTICLE 8.

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

Section 8.02 Legal Defeasance and Discharge.

Upon the Issuer’s exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Issuer and each of the Guarantors will, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have been discharged from their respective obligations with respect to all outstanding Notes (including the Guarantees) on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Issuer and the Guarantors will be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes (including the Guarantees), which will thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 hereof and the other Sections of this Indenture referred to in clauses (1) and (2) below, and to have satisfied all their other Obligations under such Notes, the Guarantees and this Indenture (and the Trustee, on demand of and at the expense of the Issuer, shall execute proper instruments acknowledging the same), except for the following provisions which will survive until otherwise terminated or discharged hereunder:

(1) the rights of Holders of outstanding Notes to receive payments in respect of the principal, interest, premium, Additional Amounts and Additional Interest, if any, on such Notes when such payments are due from the trust referred to in Section 8.04 hereof;

(2) the Issuer’s obligations with respect to such Notes under Article 2 and Section 4.02 hereof;

For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes

and Guarantees, the Issuer and the Guarantors may omit to comply with and will have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply will not constitute a Default or an Event of Default under Section 6.01 hereof, but, except as specified above, the remainder of this Indenture and such Notes and Guarantees will be unaffected thereby. In addition, upon the Issuer’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03 hereof, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, Sections 6.01(3) through 6.01(5) hereof will not constitute Events of Default.

Section 9.02 With Consent of Holders of Notes.

Except as provided below in this Section 9.02, the Issuer, the Guarantors and the Trustee may amend or supplement this Indenture, the Notes, the Guarantees, the Intercreditor Agreement, the Subordinated Intercompany Note Proceeds Loan, the Note Security Documents and Registration Rights Agreement with the consent of the Holders of at least a majority in principal amount of the Notes (including, without limitation, Additional Notes, if any) then outstanding voting as a single class (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of, premium or Additional Amounts, if any, and Additional Interest, if any, or interest on the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture, the Notes, the Guarantees, the Intercreditor Agreement, the Subordinated Intercompany Note Proceeds Loan, the Note Security Documents and the Registration Rights Agreement may be waived with the consent of the Holders of a majority in principal amount of the then outstanding Notes voting as a single class (including consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes).

Upon the request of the Issuer accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee of the documents described in Section 7.03 hereof, the Trustee will join with the Issuer and the Guarantors in the execution of such amended or supplemental indenture unless such amended or supplemental indenture directly affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but will not be obligated to, enter into such amended or supplemental Indenture.

It shall not be necessary for the consent of the Holders of Notes under this Section 9.02 to approve the particular form of any proposed amendment or waiver, but it is sufficient if such consent approves the substance thereof.

After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Issuer will mail to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Issuer to mail such notice, or any defect therein, will not, however, in any way impair or affect the validity of any such amended or supplemental indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a majority in aggregate principal amount of the Notes then outstanding voting as a single class may waive compliance in a particular instance by the Issuer with any provision of this Indenture, the Notes, or the Guarantees. However, without the consent of each Holder affected, an amendment, supplement or waiver under this Section 9.02 may not (with respect to any Notes held by a non-consenting Holder):

(1) reduce the principal amount of Notes whose Holders must consent to an amendment, supplement or waiver;

(2) reduce the principal of or change the Stated Maturity of any Note or alter the provisions with respect to the redemption of the Notes;

(3) reduce the rate of or change the Stated Maturity of any payment of interest or Additional Interest on any Note;

(4) waive a Default or Event of Default in the payment of principal, premium, interest, Additional Amounts, if any, and Additional Interest, if any, on the Notes (except a rescission of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of the Notes and a waiver of the payment default that resulted from such acceleration);

(5) make any Note payable in money other than that stated in the Notes;

(6) make any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of Holders of Notes to receive payments of principal of, premium, interest, Additional Interest or Additional Amounts on the Notes;

(7) waive a redemption payment with respect to any Note;

(8) change the ranking of the Notes, the Guarantees or the security created pursuant to the Note Security Documents;

(9) make any change in the foregoing amendment and waiver provisions.

In addition, any amendment to, or waiver of, the provisions of this Indenture, the Notes, the Guarantees, the Subordinated Intercompany Note Proceeds Loan, the Intercreditor Agreement or the Note Security Documents relating to the release of any Guarantor from any Obligation under its Guarantee or this Indenture (except in accordance with this Indenture and the Intercreditor Agreement) or of the security for the Notes and the Guarantees (except in accordance with this Indenture and the Intercreditor Agreement), in either case, that adversely affects the rights of the Holders of the Notes will require the consent of the Holders of at least 90% in aggregate principal amount of Notes then outstanding.

Section 9.03 Compliance with Trust Indenture Act.

Every amendment or supplement to this Indenture or the Notes shall be set forth in a amended or supplemental indenture that would comply with the TIA as then in effect as if this Indenture were required to be qualified under the TIA.

Section 9.04 Revocation and Effect of Consents.

Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of a Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the waiver, supplement or amendment becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder.

Section 9.05 Notation on or Exchange of Notes.

The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Issuer in exchange for all Notes may issue and the Trustee shall, upon receipt of an Authentication Order, authenticate new Notes that reflect the amendment, supplement or waiver.

Failure to make the appropriate notation or issue a new Note will not affect the validity and effect of such amendment, supplement or waiver.

Section 9.06 Trustee to Sign Amendments, etc.

The Trustee will sign any amended or supplemental indenture authorized pursuant to this Article 9 if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. The Issuer and the Guarantors may not sign an amended or supplemental indenture until the respective Board of Directors approves it. In executing any amended or supplemental indenture, the Trustee will be entitled to receive and (subject to Section 7.02 hereof)

will be fully protected in relying upon, in addition to the documents required by Section 13.04 hereof, an Officers’ Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture.

and, in the case of clauses (2), (3) and (4) the proceeds are applied an accordance with the Intercreditor Agreement, then the Trustee shall: (i) in the case of clause (1), upon such Legal Defeasance or satisfaction and discharge, or (ii) in the case of clauses (2), (3) and (4), concurrently upon receiving written confirmation from the Security Trustee that the provisions of such clause have been or will be complied with, release the Liens on the Inmarsat Ventures Limited Shares pursuant to this Indenture and the Share Charge, provided that, in the case of clauses (2), (3) and (4), the Trustee shall not release the Lien over the proceeds of the sale of the asset sold.

(c) In connection with the foregoing, the Trustee will execute, deliver and acknowledge any necessary or proper instruments of termination, satisfaction or release to evidence the release of any Pledged Collateral permitted to be released pursuant to the foregoing provisions.

(d) No Pledged Collateral may be released from the Lien and security interest created by the Note Security Documents pursuant to the provisions of the Note Security Documents unless the certificates required by Section 10.03 have been delivered to the Trustee.

(e) Save as specifically set forth in the Intercreditor Agreement or pursuant to Sections 10.02(b)(3) or 10.02(b)(4) hereof, at any time when a Default or Event of Default has occurred and is continuing, no release of Pledged Collateral pursuant to the provisions of the Note Security Documents will be effective as against the Holders of Notes.

(f) The release of any Pledged Collateral from the terms of this Indenture and the Note Security Documents will not be deemed to impair the security under this Indenture in contravention of the provisions hereof if and to the extent the Pledged Collateral is released pursuant to the terms of the Note Security Documents and the Intercreditor Agreement. The Issuer and the Guarantors will comply with the provisions of TIA § 314. To the extent applicable, the Issuer and the Guarantors will cause TIA § 313(b), relating to reports, and TIA § 314(d), relating to the release of property or securities from the Lien and security interest of the Note Security Documents and relating to the substitution therefor of any property or securities to be subjected to the Lien and security interest of the Note Security Documents, to be complied with. Any certificate or opinion required by TIA § 314(d) may be made by an Officer of the Issuer or any Guarantor except in cases where TIA § 314(d) requires that such certificate or opinion be made by an independent Person, which Person will be an independent engineer, appraiser or other expert selected or approved (such approval not to be unreasonably withheld) by the Trustee.

Notwithstanding anything to the contrary in this paragraph, the Issuer and the Guarantors will not be required to comply with all or any portion of TIA §314(d) if they determine, in good faith based on advice of counsel, that under the terms of TIA §314(d) and/or any interpretation or guidance as to the meaning thereof of the SEC and its staff, including “no action” letters or exemptive orders, all or any portion of TIA §314(d) is inapplicable to one or a series of releases of collateral.

Section 10.03 Certificates of the Issuer.

The Issuer will furnish to the Trustee, prior to each proposed release of Pledged Collateral pursuant to the Note Security Documents:

(1) all documents required by TIA §314(d); and

(2) an Opinion of Counsel, which may be rendered by internal counsel to the Issuer, to the effect that such accompanying documents constitute all documents required by TIA §314(d) and, if applicable, such release complies with the Note Security Documents and the Intercreditor Agreement.

The Trustee may, to the extent permitted by Sections 7.02 and 7.03 hereof, accept as conclusive evidence of compliance with the foregoing provisions the appropriate statements contained in such documents and such Opinion of Counsel.

Section 10.04 Certificates of the Trustee.

In the event that the Issuer wishes to release Pledged Collateral in accordance with the Note Security Documents and has delivered the certificates and documents required by the Note Security Documents and Sections 10.02 and 10.03 hereof, the Trustee will determine whether it has received all documentation required by TIA § 314(d) in connection with such release and, based on such

determination and the Opinion of Counsel delivered pursuant to Section 10.03(2), will deliver a certificate to the Note Security Trustee setting forth such determination.

Section 10.05 Authorization of Actions to Be Taken by the Trustee Under the Note Security Documents.

(a) Notwithstanding any provision of this Indenture to the contrary, for so long as required by any Intercreditor Agreement, the Trustee may only take Enforcement Action under the Share Charge at the direction of the Holders of Notes representing at least 50.01% in principal amount of all outstanding Notes, and under the Share Charge and the Pledge Agreement as otherwise permitted by the Intercreditor Agreement.

(b) Subject to the foregoing and to the provisions of Section 7.02 and 7.03 hereof, the Trustee may, in its sole discretion and without the consent of the Holders of Notes, take (and direct the Security Trustee to take) and shall take (at the direction of the Holders) all actions necessary or appropriate in order to:

(1) enforce any of the terms of the Note Security Documents or the Intercreditor Agreement; and

(2) collect and receive any and all amounts payable in respect of the Obligations of the Issuer or any Guarantor hereunder or under the Note Security Documents.

(c) Subject to the foregoing and to the Intercreditor Agreement, the Trustee will have power to institute and maintain such suits and proceedings as it may deem expedient to prevent any impairment of the Pledged Collateral by any acts that may be unlawful or in violation of the Note Security Documents, the Intercreditor Agreement or this Indenture, and such suits and proceedings as the Trustee may deem expedient to preserve or protect its interests and the interests of the Holders of Notes in the Pledged Collateral (including power to institute and maintain suits or proceedings to restrain the enforcement of or compliance with any legislative or other governmental enactment, rule or order that may be unconstitutional or otherwise invalid if the enforcement of, or compliance with, such enactment, rule or order would impair the security interest hereunder or be prejudicial to the interests of the Holders of Notes or of the Trustee).

Section 10.06 Authorization of Receipt of Funds by the Trustee Under the Note Security Documents.

The Trustee is authorized to receive any funds for the benefit of the Holders of Notes distributed under the Note Security Documents or the Intercreditor Agreement, and to make further distributions of such funds to the Holders of Notes according to the provisions of this Indenture.

Section 10.07 Termination of security.

Upon the full and final payment and performance of all Obligations of the Issuer and the Guarantors under this Indenture, the Notes and the Guarantees, the Trustee will release the Liens pursuant to this Indenture and the Note Security Documents.

ARTICLE 11.

GUARANTEES

Section 11.01 Guarantee.

(a) Subject to this Article 11, each of the Guarantors hereby, jointly and severally, unconditionally guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or the obligations of the Issuer hereunder or thereunder, that:

(1) the principal of, interest, premium, and Additional Amounts, if any, and Additional Interest, if any, on the Notes will be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of, interest, Additional Amounts, if any, and Additional Interest, if any, (to the extent permitted by law), on the Notes, and all other Obligations of the Issuer to the Holders or the Trustee hereunder or thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and

(2) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at stated maturity, by acceleration or otherwise.

Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors will be jointly and severally obligated to pay the same immediately upon (in the case of the Subsidiary Guarantees) maturity of the Guarantees in accordance with Section 11.02(b) hereof. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection.

(b) No Subsidiary Guarantee will mature (and no amount will become due or payable thereunder) until:

(1) an Event of Default under Sections 6.01(1) or (2) hereof has occurred and is continuing; and

(2) either:

(a) 179 days has elapsed since the date of such Event of Default; or

(b) if earlier, (A) an Insolvency Event in respect of the relevant Subsidiary Guarantor has occurred, (B) a Senior Declared Default has occurred and is continuing, or (C) the Senior Finance Parties have taken any Enforcement Action in respect of any Senior Debt of the relevant Subsidiary Guarantor.

Each Guarantor will notify the Trustee in writing upon maturity of its Guarantee.

(c) The Guarantors hereby agree that their obligations hereunder are unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Issuer, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Issuer, any right to require a proceeding first against the Issuer, protest, notice and all demands whatsoever and covenant that this Guarantee will not be discharged except by complete performance of the obligations contained in the Notes and this Indenture.

(d) If any Holder or the Trustee is required by any court or otherwise to return to the Issuer, the Guarantors or any custodian, trustee, liquidator or other similar official acting in relation to either the Issuer or the Guarantors, any amount paid by either to the Trustee or such Holder, this Guarantee, to the extent theretofore discharged, will be reinstated in full force and effect.

(e) Each Guarantor agrees that it will not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on the

one hand, and the Holders and the Trustee, on the other hand, (1) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6 hereof for the purposes of this Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (2) in the event of any declaration of acceleration of such obligations as provided in Article 6 hereof, such obligations (whether or not due and payable) will forthwith become due and payable by the Guarantors for the purpose of this Guarantee. The Guarantors will have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Guarantee.

Section 11.02 Subordination of Subsidiary Guarantees.

(a) Each Subsidiary Guarantor agrees, and each Holder by accepting a Note agrees, that the Indebtedness evidenced by each Subsidiary Guarantee is subordinated in right of payment, to the extent and in the manner provided in this Article 11.02, to the prior payment in full of all Senior Debt of such Subsidiary Guarantor (whether outstanding on the date hereof or hereafter created, incurred, assumed or guaranteed), and that the subordination is for the benefit of the holders of Senior Debt.

(b) If:

(1) any order is made or resolution passed for the suspension of payments, a moratorium of any indebtedness, winding-up, dissolution, administration or reorganization (by way of voluntary arrangement, scheme of arrangement or otherwise) or any obligor under the Senior Credit Agreement, the Notes or the Guarantees;

(2) any such obligor enters into any composition, assignment or arrangement with its creditors generally;

(3) any liquidator, receiver, administrator, administrative receiver, compulsory manager or other similar officer is appointed in respect of any obligor or any of its assets; or

(4) or any analogous event occurs in any jurisdiction,

then, clause (c) below shall apply.

(c) Upon the occurrence of any of the events specified in Section 11.02(b) hereof, until all Senior Debt of the relevant Subsidiary Guarantor is paid in full in cash, each Holder of the Notes shall:

(1) hold all payments and distributions in cash or in kind received or receivable by it in respect of the relevant Subsidiary Guarantee in trust for the holders of Senior Debt of such Subsidiary Guarantor;

(2) on demand by the holder of such Senior Debt or their agent, pay an amount equal to such Subsidiary Guarantee owing to them and discharged, by set-off or otherwise, to the holders of such Senior Debt or their agent;

(3) promptly direct any trustee in bankruptcy, liquidator, assignee or other person distributing the assets of the relevant Subsidiary Guarantor or their proceeds to pay distributions in respect of such Subsidiary Guarantee directly to the holders of such Senior Debt of such Subsidiary Guarantor or their agent; and

(4) promptly use their reasonable endeavors to undertake any actions requested by the holders of Designated Senior Debt of such Subsidiary Guarantor to give effect to this clause (c);

provided, however, that holders of the Notes shall be entitled to receive and retain Permitted Junior Securities.

(d) Until repayment in full in cash of all Senior Debt of a Subsidiary Guarantor, such Subsidiary Guarantor will not:

(1) pay any amount on or in respect of, or make any distribution in respect of, its Subsidiary Guarantee, in cash or in kind or apply any money or property in or towards discharge of its Subsidiary Guarantee, except in accordance with Section 11.02(f) hereof; or

(2) exercise any set-off against its Subsidiary Guarantee, except in accordance with Section 11.02(f) hereof.

(e) Until repayment in full in cash of all Senior Debt of a Subsidiary Guarantor, no holder of the Notes shall:

(1) receive any payment from such Subsidiary Guarantor of any amount on or in respect of, or any distribution from such Subsidiary Guarantor in respect of, its Subsidiary Guarantee, in cash or in kind, or apply any money or property in or towards discharge of such Subsidiary Guarantee, except in accordance with Section 11.02(f) hereof; or

(2) exercise any set-off against any Subsidiary Guarantee, except in accordance with Section 11.02(f) below.

(f) Notwithstanding the provisions of Section 11.02(d) and 11.02(e) hereof, a Subsidiary Guarantor may pay and a holder of the Notes may receive:

(1) Permitted Junior Securities in respect of the Subsidiary Guarantees; and

(2) subject to the provisions of Section 11.02(g) hereof, payments on the Subsidiary Guarantees in respect of any interest, fees, expenses or other amounts (including reasonable legal fees) and taxes in respect of the Subsidiary Guarantees.

(g) The payments described in Section 11.02(f)(2) hereof shall be suspended if:

(1) a payment event of default under any Senior Debt of the relevant Subsidiary Guarantor occurs (until such event of default has been waived or remedied); or

(2) any other event of default under any Designated Senior Debt of the relevant Subsidiary Guarantor has occurred and the agent with respect thereto has served a notice of such non-payment default (a “High Yield Notes Stop Notice”) to the Trustee and the Issuer, until the earliest of:

(a) 179 days after the High Yield Notes Stop Notice was served on the Issuer and the Trustee by such agent;

(b) if a Funding Loan Standstill Period is in effect in accordance with the provisions of the Intercreditor Agreement after the default giving rise to the High Yield Notes Stop Notice, the date on which that standstill period expires;

(c) the date on which such event of default has been waived or remedied;

(d) the date on which the agent under such Designated Senor Debt delivers notice to the Issuer and the Trustee canceling the High Yield Notes Stop Notice; and

(e) the date of repayment in full of all obligations under such Designated Senior Debt.

(h) For the purposes of Section 11.02(g)(2), the agent under Designated Senior Debt referred to therein must deliver a High Yield Notes Stop Notice within 180 days following the default specified therein. In addition, no new High Yield Notes Stop Notice may be delivered by the holders of Designated Senior Debt unless and until 360 days have elapsed since the delivery of the immediately prior High Yield Notes Stop Notice and the agent under Designated Senior Debt may only serve one High Yield Notes Stop Notice with respect to the same event or set of circumstances.

(i) If the Trustee or any Holder of the Notes receives a payment in respect of any Subsidiary Guarantee in violation of the foregoing then, the Trustee or the Holder of the Notes, as the case may be, shall:

(1) within three Business Days, notify details of the receipt or recovery to the agent for the holders of Senior Debt;

(2) hold any such assets and moneys received or recovered for it on trust for the holders of Senior Debt; and

(3) within three Business Days of demand by the agent for the holders of Senior Debt, pay an amount equal to such receipt or recovery to such agent.

(j) With respect to the holders of Senior Debt, the Trustee undertakes to perform only those obligations on the part of the Trustee as are specifically set forth in this Article 11, and no implied covenants or obligations with respect to the holders of Senior Debt will be read into this Indenture against the Trustee. The Trustee will not be deemed to owe any fiduciary duty to the holders of Senior Debt, and will not be liable to any such holders if the Trustee pays over or distributes to or on behalf of Holders or any Guarantor or any other Person money or assets to which any holders of Senior Debt are then entitled by virtue of this Article 11, except if such payment is made as a result of the willful misconduct or gross negligence of the Trustee.

(k) After all Senior Debt is paid in full and until the Notes are paid in full, Holders of Notes will be subrogated (equally and ratably with all other Indebtedness pari passu with the Notes) to the rights of holders of Senior Debt to receive distributions applicable to Senior Debt to the extent that distributions otherwise payable to the Holders of Notes have been applied to the payment of Senior Debt. A distribution made under this Article 11 to holders of Senior Debt that otherwise would have been made to Holders of Notes is not, as between the Guarantors and Holders, a payment by the Guarantors on the Notes.

(l) This Article 11 defines the relative rights of Holders of Notes and holders of Senior Debt. Nothing in this Indenture will:

(1) impair, as between the Guarantors and Holders of Notes, the obligation of the Guarantors, which is absolute and unconditional, to pay principal, premium, interest, Additional Amounts and Additional Interest on the Notes in accordance with their terms;

(2) affect the relative rights of Holders of Notes and creditors of the Guarantors other than their rights in relation to holders of Senior Debt; or

(3) prevent the Trustee or any Holder of Notes from exercising its available remedies upon a Default or Event of Default, subject to the rights of holders and owners of Senior Debt to receive distributions and payments otherwise payable to Holders of Notes and subject to restrictions contained in any Intercreditor Agreement.

If the Guarantors fail because of this Article 11 to pay principal of, premium, interest, Additional Amounts or Additional Interest on a Note on the due date, the failure is still a Default or Event of Default.

(m) Each Holder of Notes, by the Holder’s acceptance thereof, authorizes and directs the Trustee on such Holder’s behalf to take such action as may be necessary or appropriate to effectuate the subordination as provided in this Article 11, and appoints the Trustee to act as such Holder’s attorney-in-fact for any and all such purposes. If the Trustee does not file a proper proof of claim or proof of debt in the form required in any proceeding referred to in Section 6.09 hereof at least 30 days before the expiration of the time to file such claim, the holders of Senior Debt are hereby authorized to file an appropriate claim for and on behalf of the Holders of the Notes.

(n) In addition to the foregoing, the Subsidiary Guarantees are subject to the Intercreditor Agreement and each Holder of Notes, by its acceptance thereof, consents and agrees to the terms of the Intercreditor Agreement as the same may be in effect or may be amended from time to time in accordance with this Indenture. Each Holder, by its acceptance of a Note, directs the Trustee to enter into the Intercreditor Agreement and to perform its obligations and exercise its rights thereunder in accordance therewith.

Section 11.03 Limitation on Guarantor Liability.

Each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Guarantee of such Guarantor not constitute a fraudulent transfer, a fraudulent conveyance or a transaction at under value for purposes of Bankruptcy Law or any similar law to the extent applicable to any Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of such Guarantor will be limited to the maximum amount that will, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under this Article 11, result in the obligations of such Guarantor under its Guarantee not constituting a fraudulent transfer, fraudulent conveyance or transaction at under value. In addition, the Board of Directors of the Issuer and each Guarantor is satisfied, after due and careful consideration of the terms of the Guarantees, that the giving of the Guarantees by the Guarantors is for the purposes and to the benefit of the Issuer and each Guarantor.

Section 11.04 Execution and Delivery of Guarantee.

To evidence its Guarantee set forth in Section 11.01 hereof, each Guarantor hereby agrees that a notation of such Guarantee substantially in the form attached as Exhibit E hereto will be endorsed by an Officer of such Guarantor on each Note authenticated and delivered by the Trustee and that this Indenture will be executed on behalf of such Guarantor by one of its Officers.

Each Guarantor hereby agrees that its Guarantee set forth in Section 11.01 hereof will remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Guarantee.

If an Officer whose signature is on this Indenture or on the Guarantee no longer holds that office at the time the Trustee authenticates the Note on which a Guarantee is endorsed, the Guarantee will be valid nevertheless.

The delivery of any Note by the Trustee, after the authentication thereof hereunder, will constitute due delivery of the Guarantee set forth in this Indenture on behalf of the Guarantors.

In the event that the Issuer, Inmarsat Group Limited or any of their Restricted Subsidiaries creates or acquires any new Restricted Subsidiaries after the date of this Indenture, if required by Section 4.19 hereof, the Issuer will cause such Restricted Subsidiary to comply with the provisions of Section 4.19 hereof and this Article 11, to the extent applicable.

Section 11.05 Guarantors May Consolidate, etc., on Certain Terms.

Without prejudice to Section 11.06, neither Inmarsat Group Limited nor Inmarsat Investments Limited may sell or otherwise dispose of all or substantially all of its assets to, or consolidate, merge, amalgamate or otherwise combine with or into (whether or not Inmarsat Group Limited or Inmarsat Investments Limited (as applicable) is the surviving person), any person unless they comply with Section 5.01.

Without prejudice to Section 11.06, no Subsidiary Guarantor (other than Inmarsat Investments Limited) may sell or otherwise dispose of all or substantially all of its assets to, or consolidate, merge, amalgamate or otherwise combine with or into (whether or not such Subsidiary Guarantor is the surviving Person) another Person, unless:

(1) immediately prior to and after giving effect to that transaction, no Default or Event of Default exists; and

(2) either:

(a) the Person acquiring the property in any such sale or disposition or the Person formed by or surviving any such consolidation or merger assumes all the obligations of that Guarantor, pursuant to a supplemental indenture in form and substance reasonably satisfactory to the Trustee, under this Indenture, its Guarantee, the Registration Rights Agreement, the Intercreditor Agreement and the Note Security Documents; or

(b) such sale is undertaken in accordance with, and the Net Proceeds of such sale or other disposition are applied in accordance with, the applicable provisions of this Indenture, including without limitation, Section 4.10 hereof.

In case of any such sale, consolidation or merger, and the upon compliance with clause (2) of the second paragraph of this Section 11.05, such successor Person will succeed to and be substituted for the relevant Subsidiary Guarantor with the same effect as if it had been named herein as a Guarantor. Such successor Person thereupon may cause to be signed any or all of the Guarantees to be endorsed upon all of the Notes issuable hereunder which theretofore shall not have been signed by the Issuer and delivered to the Trustee. All the Guarantees so issued will in all respects have the same legal rank and benefit under this Indenture as the Guarantees theretofore and thereafter issued in accordance with the terms of this Indenture as though all of such Guarantees had been issued at the date of the execution hereof.

Except as set forth in Articles 4 and 5 hereof, and notwithstanding clauses (a) and (b) above, nothing contained in this Indenture or in any of the Notes will prevent any consolidation or merger of a Guarantor with or into the Issuer or another Guarantor, or will prevent any sale or conveyance of the property of a Guarantor as an entirety or substantially as an entirety to the Issuer or another Guarantor.

Any Guarantor not released from its obligations under its Guarantee as provided in this Section 11.06 will remain liable for the full amount of principal of and interest on the Notes and for the other obligations of any Guarantor under this Indenture as provided in this Article 11.

SATISFACTION AND DISCHARGE

Section 12.01 Satisfaction and Discharge.

This Indenture will be discharged and will cease to be of further effect as to all Notes issued hereunder, when:

Any notice or communication will also be so mailed to any Person described in TIA § 313(c), to the extent required by the TIA. Failure to mail a notice or communication to a Holder or any defect in it will not affect its sufficiency with respect to other Holders.

If the Issuer mails a notice or communication to Holders, it will mail a copy to the Trustee and each Agent at the same time.

Holders may communicate pursuant to TIA § 312(b) with other Holders with respect to their rights under this Indenture or the Notes. The Issuer, the Trustee, the Registrar and anyone else shall have the protection of TIA § 312(c).
