LOAN PROVISIONS

SECTION 2.01. THE COMMITMENT.

(a) THE LOANS. The Lenders agree, subject to the terms hereof and satisfaction of the conditions precedent contained herein, from the Effective Date through the Maturity Date to make extensions of credit to the Borrower (each such extension of credit, a “LOAN” and, collectively, the “LOANS”) upon the request of the Borrower in accordance with Section 2.03, on any Milestone Payment Date for the TerreStar-2 Satellite in order for the Borrower to make the related Milestone Payment to the Satellite Manufacturer as provided below; provided that no Loan shall exceed the Maximum Amount, and provided, further, that each Loan shall be in an amount at least equal to the full Milestone Payment (or, if less than the full Milestone Payment, $500,000 and whole number multiples of $100,000 in excess thereof). The Lenders are authorized to make Loans under this Agreement based on written instructions received from an Officer of the Borrower, and the Borrower shall indemnify and hold Collateral Agent and the Lenders harmless for any damages or losses suffered by Collateral Agent or such Lender as a result of reliance on such instructions. To the extent permitted by applicable law, the Lenders shall disburse funds to the Borrower by wiring the amount of each Loan made by such Lender under this Section 2.01 to the Deposit Account or in such other manner and otherwise in accordance with the Borrower’s instructions. Each Loan under this Agreement shall be granted by the Lenders pro rata on the basis of their then-applicable Commitments. It is understood that no Lender shall be responsible for any default by any other Lender in its obligation to make Loans hereunder and that each Lender shall be obligated to make the Loans provided to be made by it hereunder, regardless of the failure of any other Lender to fulfill its commitments hereunder. Under no circumstances shall any Lender be obligated to make any Loan if, after making such Loan, the aggregate principal amount of the Loans made by such Lender would exceed the Commitment of such Lender then in effect. Amounts prepaid or repaid in respect of the Loans may not be reborrowed.

(b) PURPOSE. The Borrower shall, subject to the terms and conditions hereof, use each Loan solely to pay the applicable Milestone Payment owed to the Satellite Manufacturer pursuant to the TerreStar-2 Construction Agreement.

SECTION 2.02. SECURITY. All obligations of the Borrower under this Agreement and the other Loan Documents shall be secured by the Collateral as set forth in the Security

Documents, subject to the condition that if the Loans (together with accrued and unpaid interest thereon, fees and all other amounts due and payable under the Loan Documents) to be so secured shall be repaid in full, and the Commitment shall have terminated or expired, Collateral Agent shall release the Collateral from the security interest created therein. The Borrower shall enter into on or before the Effective Date the Security Documents, including the Security Agreement, granting to Collateral Agent a valid Lien in or on all Collateral, which Lien shall be subject to no prior Liens (provided that the Collateral may be subject to Collateral Permitted Liens), shall be perfected at all times on and after the Effective Date and shall be otherwise in accordance with the terms hereof, and, as a condition to the Effective Date, the Lenders shall be satisfied by receipt of legal opinions that such grant is not void or subject to avoidance if the Borrower becomes the subject of an insolvency proceeding.

SECTION 2.03. REQUEST FOR A LOAN. To request a Loan, the Borrower shall notify the Lenders of such request by delivery of a Notice of Borrowing, in substantially the form of Exhibit A or otherwise in a form approved by the Required Lenders and signed by the Borrower, not later than 10 Business Days before the date of the proposed Loan.

SECTION 2.04. RECORDS; PROMISSORY NOTES.

(a) MAINTENANCE OF RECORDS BY THE LENDERS. Each Lender shall maintain records evidencing the indebtedness of the Borrower to such Lender resulting from the Loans in which it shall record (i) the amount of any principal or interest due and payable or to become due and payable from the Borrower hereunder and (ii) the amount of any sum received by such Lender hereunder.

(b) EFFECT OF ENTRIES. The entries made in the respective records maintained pursuant to paragraph (a) of this Section shall be prima facie evidence of the existence and amounts of the obligations recorded therein; provided that the failure of any Lender to maintain such records or any error therein shall not in any manner affect the obligation of the Borrower to repay the Loans in accordance with the terms of this Agreement.

(c) PROMISSORY NOTES. Any Lender may request that a Loan be evidenced by a Note substantially in the form of EXHIBIT D. In such event, the Borrower shall prepare, execute and deliver to the requesting Lender a Note payable to such Lender. Thereafter, the Loan evidenced by such Note and interest thereon shall at all times (including after assignment pursuant to Section 10.04) be represented by a Note in such form payable to the payee named therein (or, if such Note is a registered note, to such payee and its registered assigns).

SECTION 2.05. REPAYMENT OF THE LOANS. The Borrower hereby unconditionally promises to pay to the Lenders the unpaid principal amount of the Loans, together with accrued and unpaid interest thereon, on the Maturity Date.

SECTION 2.06. PREPAYMENT OF THE LOANS AND COMMITMENT REDUCTIONS.

(a) OPTIONAL PREPAYMENTS. The Borrower may, upon three Business Days prior written notice to the Lenders, prepay Loans, in whole or in part, in amounts of at least

$5,000,000 or any whole number multiple of $1,000,000 in excess thereof and at the following prepayment prices (expressed as a percentage of the principal amount of the Loans being prepaid), if prepaid during the twelve-month period ending on the anniversary of the Effective Date set forth below:

(d) NOTICES, ETC. The Borrower shall notify the Lenders by telephone (confirmed by telecopy) of any prepayment hereunder not later than 11:00 a.m., New York City time, three Business Days before the date of prepayment. Each such notice shall be irrevocable and shall specify the prepayment date, the principal amount of the Loans or the portion thereof to be prepaid and a reasonably detailed calculation of the amount of such prepayment. Each partial prepayment of the Loans shall be in an amount that would be permitted as provided in Section 2.06(a), except as necessary to apply fully the required amount of a mandatory prepayment. Prepayments shall be accompanied by the applicable unpaid fees and all other amounts owing under this Agreement and the other Loan Documents and accrued and unpaid interest to the extent required by Section 2.07 and shall be made in the manner specified in Section 2.09.

SECTION 2.07. INTEREST.

(a) RATE. The unpaid principal amount of each Loan shall bear interest from the date such Loan is made under Section 2.01 until paid in full at a rate per annum that shall at all times be equal to the Interest Rate.

(b) ADDITIONAL INTEREST. Notwithstanding Section 2.07(a):

(i) if the Information Statement shall not have been submitted to the Commission on or prior to February 29, 2008, the Interest Rate then in effect shall be increased from March 1, 2008 to the date of the Spectrum Contribution Approval by one (1) percentage point per annum;

(ii) if the Information Statement shall not have been submitted to the shareholders of TerreStar Parent on or prior to April 30, 2008, the Interest Rate then in effect shall be increased from May 1, 2008 to the date of the Spectrum Contribution Approval by one (1) percentage point per annum;

(iii) if the Borrower fails to secure the FCC ATC Authorization on or prior to the ATC Operational Date, the Interest Rate then in effect shall be increased by one (1) percentage point per annum on each of (A) the ATC Operational Date and (B) until Borrower secures the FCC ATC Authorization, (x) the date that is one (1) month after the ATC Operational Date and (y) the date that is two (2) months after the ATC Operational Date; provided that all additional interest pursuant to this clause (iii) shall cease to apply as of the date that the Borrower has secured the FCC ATC Authorization; and

(iv) the aggregate amount of all such additional interest shall be payable in cash on demand by the Lenders.

(c) DEFAULT INTEREST. From and after the occurrence and during the continuance of any Event of Default, upon notice by the Required Lenders to the Borrower, the Borrower shall pay interest on the principal amount of all Loans and all other due and unpaid Obligations under this Agreement and the other Loan Documents, to the extent permitted by applicable law, at the Interest Rate then in effect plus two (2) percentage points per annum. All such interest shall be payable in cash on demand by the Lenders.

(d) PAYMENT OF INTEREST. Interest on each Loan shall accrue from and including the date such Loan is made under Section 2.01 to but excluding the date of any repayment thereof and shall be payable quarterly in arrears on the last day of each March, June, September and December (each an “INTEREST PAYMENT DATE”), beginning with the fiscal quarter ending March 31, 2008, and on any prepayment (on the amount prepaid), at maturity (whether by acceleration or otherwise) and, after such maturity, on demand by the Lenders. On each Interest Payment Date the Borrower shall (i) pay in cash all interest which shall have accrued at the Interest Rate on the Loans through such Interest Payment Date or (ii) solely during the period from the Effective Date to, but not including, the fourth anniversary thereof, at the election of the Borrower, (A) defer payment in cash of all interest which shall have accrued at the Interest Rate on the Loans through such Interest Payment Date or (B) make a cash payment of an amount and defer payment of an amount so that the combined amount of the payment and the deferral is equal to all interest accrued at the Interest Rate on the Loans through such Interest Payment Date. Upon any such deferral of an interest payment in accordance with this Section 2.07(d)(ii), the amount of the deferred payment shall become and be deemed to be additional outstanding principal of the Loans, on which interest shall begin accruing hereunder on the date of any such deferral. Such additional outstanding principal amount of the Loans is sometimes referred to in this Agreement as “PIK INTEREST”. To the extent requested from time to time by the Lenders, the Borrower shall issue additional or replacement Notes to evidence the increased principal amount of Loans resulting from the deferral of interest payments hereunder; provided that the absence of or failure to request or issue such additional or replacement Notes shall not affect the validity of such obligation, its character as principal or the Borrower’s obligations with respect thereto. Interest accrued on Loans and other monetary Obligations of the Borrower and the Guarantors hereunder and under the other Loan Documents after the date such amount is due and payable (whether on the Maturity Date, upon acceleration or otherwise) shall be payable upon demand by the Lenders.

(e) COMPUTATION. All interest hereunder shall be computed on the basis of a year of 360 days, and shall be payable for the actual number of days elapsed (including the first day but excluding the last day).

SECTION 2.08. TAXES.

(a) PAYMENTS TO BE FREE OF TAXES. Any and all payments by or on account of any obligation of the Borrower hereunder or under any other Loan Document shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes. In furtherance of the foregoing, if the Borrower shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section) the Lenders receive an amount equal to the sum they would have

received had no such deductions been made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law.

(b) PAYMENT OF OTHER TAXES BY THE BORROWER. In addition, the Borrower shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

(c) INDEMNIFICATION BY THE BORROWER. The Borrower shall indemnify Collateral Agent and the Lenders, within 10 Business Days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) paid by Collateral Agent or such Lender and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Borrower by Collateral Agent or such Lender shall be conclusive absent manifest error.

(d) EVIDENCE OF PAYMENTS. As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the Borrower to a Governmental Authority, the Borrower shall deliver to the Lenders the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Lenders.

(e) TAXATION OF LENDERS. Notwithstanding any provision of this Agreement to the contrary, each Lender shall be either (a) a United States person under Section 7701(a)(30) of the Code for United States federal income purposes and shall deliver to the Borrower a properly completed and executed Internal Revenue Service Form W-9 (or any subsequent versions thereof or successors thereto), or (b) entitled to an exemption from withholding tax under the laws of the United States of America, or any treaty with the United States of America, or any treaty to which the United States of America is a party, with respect to payments under any Loan Documents and shall deliver to the Borrower, at the time or times prescribed by applicable law or reasonably requested by the Borrower, such properly completed and executed documentation prescribed by applicable law as will permit such payments to be made without withholding.

(f) REFUNDS. If any Lender determines, in its sole discretion, that it has received a refund of any Indemnified Taxes or Other Taxes as to which it has been indemnified by the Borrower or with respect to which the Borrower has paid additional amounts pursuant to this Section 2.08, it shall pay over such refund to the Borrower (but only to the extent of indemnity payments made, or additional amounts paid, by the Borrower under this Section 2.08 with respect to the Indemnified Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket expenses of such Lender and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund); provided, that the Borrower, upon the request of such Lender, agrees to repay the amount paid over to the Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to such Lender in the event such Lender is required to repay such refund to such Governmental

Authority. This paragraph shall not be construed to require any Lender to make available its tax returns (or any other information relating to its taxes which it deems confidential) to the Borrower or any other Person.

SECTION 2.09. PAYMENTS GENERALLY.

(a) PAYMENTS BY THE BORROWER. The Borrower shall make each payment required to be made by it hereunder (whether of principal, interest or fees, or under Section 2.08, or otherwise) or under any other Loan Document (except to the extent otherwise provided therein) prior to 11:00 a.m., New York City time, on the date when due, in immediately available funds, without set-off, recoupment or counterclaim (it being understood and agreed that the Borrower shall not at any time offset amounts owed to it by the Satellite Manufacturer under the TerreStar-2 Construction Agreement or otherwise against amounts due and owing to Collateral Agent or any Lender hereunder or under the other Loan Documents). Any amounts received after such time on any date may, in the discretion of the Lender, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Lenders by wire transfer to the account specified for such purpose below such Lender’s name in Schedule 2.09(a), or at such other account as such Lender may specify by prior written notice to the Borrower, except as otherwise expressly provided in the relevant Loan Document. If any payment hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension. All payments hereunder or under any other Loan Document shall be made in Dollars.

(b) APPLICATION OF PAYMENTS. Upon the occurrence, and during the continuance of an Event of Default, all payments or proceeds received by Lenders hereunder or under any Loan Document in respect of any of the Obligations of the Borrower and the Guarantors hereunder and under the other Loan Documents, including, but not limited to all proceeds received by any Lender in respect of any sale, any collection from, or other realization upon all or any part of the Collateral, shall be applied in full or in part as follows: first, to the payment of all costs and expenses of such sale, collection or other realization, including reasonable compensation to Collateral Agent and its agents and counsel, and all other expenses, liabilities and advances made or incurred by Collateral Agent in connection therewith, and all amounts for which Collateral Agent is entitled to indemnification hereunder or under any Loan Document (in its capacity as Collateral Agent) and to the payment of all costs and expenses paid or incurred by Collateral Agent in connection with the exercise of any right or remedy hereunder or under any Loan Document, all in accordance with the terms hereof or thereof; and second, to the extent of any excess of such proceeds, to the payment of all other Obligations of the Borrower and the Guarantors hereunder and under the other Loan Documents for the ratable benefit of the Lenders.

(c) RATABLE SHARING. Lenders hereby agree among themselves that, except as otherwise provided in the other Loan Documents, if any of them shall, whether by voluntary payment (other than a voluntary prepayment of Loans made and applied in accordance with the terms hereof), through the exercise of any right of set off or banker’s lien, by counterclaim or cross action or by the enforcement of any right under the Loan Documents or

otherwise, or as adequate protection of a deposit treated as cash collateral under the Bankruptcy Code, receive payment or reduction of a proportion of the aggregate amount of principal, interest, amounts payable in respect of fees and other amounts then due and owing to such Lender hereunder or under the other Loan Documents (collectively, the “AGGREGATE AMOUNTS DUE” to such Lender) which is greater than the proportion received by any other Lender in respect of the Aggregate Amounts Due to such other Lender, then the Lender receiving such proportionately greater payment shall (i) notify each other Lender of the receipt of such payment and (ii) apply a portion of such payment to purchase participations (which it shall be deemed to have purchased from each seller of a participation simultaneously upon the receipt by such seller of its portion of such payment) in the Aggregate Amounts Due to the other Lenders so that all such recoveries of Aggregate Amounts Due shall be shared by all Lenders in proportion to the Aggregate Amounts Due to them; provided, that if all or part of such proportionately greater payment received by such purchasing Lender is thereafter recovered from such Lender upon the bankruptcy or reorganization of Borrower or otherwise, those purchases to that extent shall be rescinded and the purchase prices paid for such participations shall be returned to such purchasing Lender ratably to the extent of such recovery, but without interest. Borrower expressly consents to the foregoing arrangement and agrees that any holder of a participation so purchased may exercise any and all rights of banker’s lien, set off or counterclaim with respect to any and all monies owing by Borrower to that holder with respect thereto as fully as if that holder were owed the amount of the participation held by that holder.

(d) APPLICATION OF INSUFFICIENT PAYMENTS. If at any time insufficient funds are received by and available to the Lenders to pay fully all amounts of principal, interest and fees then due hereunder and under the other Loan Documents, such funds shall be applied (i) first, to pay interest and fees then due and (ii) second, to pay principal then due.

SECTION 5.13. DESIGNATION OF UNRESTRICTED SUBSIDIARIES.

Such 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 the Borrower may redesignate any Unrestricted Subsidiary to be a Restricted Subsidiary if the redesignation would not cause a Default or an Event of Default.

All Subsidiaries of Unrestricted Subsidiaries shall be automatically deemed to be Unrestricted Subsidiaries.

date and, if such Indebtedness is not permitted to be incurred as of such date under Section 6.01, the Borrower will be in default of such covenant. The Board of Directors of the Borrower may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary of the Borrower; provided that such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of the Borrower of any outstanding Indebtedness of such Unrestricted Subsidiary and such designation will only be permitted if (i) such Indebtedness is permitted under Section 6.01, calculated on a pro forma basis as if such designation had occurred at the beginning of the applicable quarterly reference period; and (ii) no Default or Event of Default would be in existence following such designation.

SECTION 5.14. MAINTENANCE OF INSURANCE.

(a) The Borrower shall obtain, or cause to be obtained, prior to the launch of the TerreStar-1 Satellite and the TerreStar-2 Satellite (as applicable) and shall maintain, or cause to be maintained, launch insurance with respect to the launch of the TerreStar-1 Satellite and the TerreStar-2 Satellite (as applicable) covering the period from the launch to 180 days or more following the launch thereof on such terms (including coverage period, exclusions, limitations on coverage, co-insurance, deductibles and coverage amount) as is customary in the industry for similar persons at the time of such launch.

(b) The Borrower shall procure and maintain, or cause to be procured and maintained, Full In-Orbit Insurance for the TerreStar-1 Satellite and the TerreStar-2 Satellite (as applicable); provided that such Full In-Orbit Insurance shall only be required if, and to the extent and on such terms (including coverage period, exclusions, limitations on coverage, co-insurance, deductibles and coverage amount) as is determined by the Board of Directors of the Borrower to be in the best interests of the Borrower as evidenced by a resolution of the Board of Directors.

(i) contain no exclusions other than customary exclusions and such specific exclusions applicable to the performance of the satellite (or portion thereof, or the type of satellite or portion thereof, as applicable) being insured as are acceptable to the Board of Directors of the Borrower in order to obtain insurance for a price that is, and on other terms and conditions that are, commercially reasonable; and

(ii) subject to the proviso in clause (b) of this Section 5.14, provide coverage for all risks of loss and damage to the TerreStar-1 Satellite and the TerreStar-2 Satellite.

(a) In the event that the Borrower or any Guarantor receives Net Insurance Proceeds relating to the TerreStar-2 Satellite, the Borrower or such Guarantor shall apply such Net Insurance Proceeds in the manner provided under Section 5.08.

SECTION 5.15. COMPLIANCE CERTIFICATES.

(a) The Borrower shall deliver to the Lenders, together with the delivery of financial information under Section 5.01(a), an Officers’ Certificate of the chief executive officer

and the chief financial officer of the Borrower as to the signers’ knowledge of the Borrower’s compliance with all conditions and covenants on its part contained in this Agreement and stating whether or not the signer knows of any Default or Event of Default that is then continuing and demonstrating compliance with such covenants in reasonable detail.

(b) The Borrower shall promptly deliver to the Lenders and in any event within five Business Days of any Officer of the Borrower becoming aware of the occurrence of any Default or Event of Default, an Officers’ Certificate setting forth the details of such Default or Event of Default and the action which the Borrower is taking or proposes to take to remedy the same.

SECTION 5.16. ADDITIONAL GUARANTEES.

(a) If at any time the Borrower or any Restricted Subsidiary acquires or creates another Domestic Subsidiary (other than a Domestic Subsidiary that is a Subsidiary, directly or indirectly, of a Foreign Subsidiary) that owns any assets that constitute or may constitute Collateral, such newly acquired or created Domestic Subsidiary shall, on the date on which it is acquired or created, become a Guarantor by executing and delivering to the Lenders a joinder agreement substantially in form of Exhibit E attached hereto and there shall be no need to re-execute, amend or restate this Agreement in connection therewith, and pursuant to which such Domestic Subsidiary will guarantee, on a joint and several basis, the full and prompt payment of the principal of, premium, if any, and interest on the Loans on a senior secured basis. Upon delivery of any such joinder agreement to the Lenders, notice of which is hereby waived by the Guarantors, each such Domestic Subsidiary shall be a Guarantor and shall be as fully a party hereto as if such Domestic Subsidiary were an original signatory hereto as a Guarantor. Each Guarantor expressly agrees that its obligations arising hereunder shall not be affected or diminished by the addition or release of any other Guarantor hereunder nor by any election of the Collateral Agent not to cause any Person to become an Guarantor hereunder. This Guaranty shall be fully effective as to any Guarantor that is or becomes a party hereto regardless of whether any other Person becomes or fails to become or ceases to be a Guarantor hereunder.

(b) The Borrower may elect to make any Foreign Subsidiary or any Affiliate a Guarantor, with the consent of any such party, by causing such Person to execute and deliver to the Lenders a joinder agreement substantially in form of Exhibit E attached hereto subject to the terms of this Agreement.

(c) Each Guarantor shall become a party to the Loan Documents applicable to it. The Borrower (i) shall cause each Subsidiary Guarantor to become a party to the Loan Documents and (ii) shall, or shall cause each Subsidiary Guarantor to, file any financing statement necessary to grant to the Collateral Agent, for the benefit of itself and the Lenders, perfected first priority security interest (subject only to Collateral Permitted Liens) in any Collateral held by such Guarantor, to the extent a security interest therein can be perfected by the filing of a financing statement.

Indebtedness with respect to assets other than Capital Stock or other Investments, including the incurrence of Indebtedness representing the financing of installments of Full In-Orbit Insurance, launch insurance premiums or launch services, 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 a Permitted Business, and Attributable Debt, in an aggregate principal amount not to exceed $50,000,000 at any time outstanding;

(iv) the incurrence by the Borrower or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to renew, refund, refinance, discharge, defease or replace, Indebtedness permitted under any other clause of this Section 6.01(b) (excluding clause (v)), provided that for purposes of any limit contained in any such other clause the aggregate amount of Indebtedness incurred pursuant to this clause (iv) outstanding at any one time shall be treated as outstanding pursuant to such other clause;

(v) the incurrence by the Borrower or any of its Restricted Subsidiaries of intercompany Indebtedness between or among the Borrower and any of its Restricted Subsidiaries; provided that:

(A) if the Borrower or any Restricted Subsidiary is the obligor on such Indebtedness and the payee is not the Borrower or a Restricted Subsidiary, such Indebtedness shall be expressly subordinated to the prior payment in full in cash of all Obligations of the Borrower and the Restricted Subsidiaries hereunder and under the other Loan Documents; and

(B) (1) any subsequent issuance or transfer of Equity Interests or any other event that results in any such Indebtedness being beneficially held by a Person other than the Borrower or a Restricted Subsidiary, (2) any sale or other transfer of any such Indebtedness to a Person that is neither the Borrower nor a Restricted Subsidiary or (3) the designation of a Restricted Subsidiary which holds Indebtedness as an Unrestricted Subsidiary will be deemed, in each case, to constitute an incurrence of such Indebtedness by the Borrower or such Restricted Subsidiary, as the case may be, that was not permitted by this clause (v);

(vi) the incurrence by the Borrower or any of its Restricted Subsidiaries of Hedging Obligations;

(vii) the Guarantee by the Borrower or any of the Restricted Subsidiaries of Indebtedness of any Restricted Subsidiary that was permitted to be incurred by another provision of this Section 6.01(b); provided that in the case of any such Guarantee by the Borrower, if the Indebtedness being guaranteed is (A) pari passu in right of payment to the Loans, then the Guarantee related to such Indebtedness shall rank equally in right of payment to the Loans, or (B) subordinated in right of payment to the Loans, then the Guarantee of such Indebtedness shall be subordinated in right of payment to the same extent to the Loans;

(viii) the incurrence of Indebtedness by the Borrower or any of its Restricted Subsidiaries arising from the honoring by a bank or other financial institution of a

check, draft or similar instrument (except in the case of daylight overdrafts) in the ordinary course of business inadvertently drawn against insufficient funds, provided, that such Indebtedness is extinguished within five (5) Business Days of incurrence;

(ix) the incurrence of Indebtedness by the Borrower or any of its Restricted Subsidiaries incurred in respect of workers’ compensation claims, self-insurance obligations, bankers’ acceptances, performance, surety and similar bonds and completion guarantees provided by the Borrower or any Restricted Subsidiary, in each case, in the ordinary course of business; and

(x) the incurrence of Indebtedness by the Borrower or any Restricted Subsidiary to finance the purchase or construction of property (real or personal) or equipment that is used for the construction of the Borrower’s terrestrial network so long as, at the time of incurrence thereof, the ratio of total consolidated Indebtedness of the Borrower and its Restricted Subsidiaries determined in accordance with GAAP (including Indebtedness under all financings under this clause (x)) to Invested Capital does not exceed 75%.

(c) The Borrower shall not permit any of the Unrestricted Subsidiaries to incur any Indebtedness other than Non-Recourse Debt. If any Non-Recourse Debt of an Unrestricted Subsidiary shall at any time cease to constitute Non-Recourse Debt or such Unrestricted Subsidiary shall be redesignated a Restricted Subsidiary, such event will be deemed to constitute an incurrence of Indebtedness by a Restricted Subsidiary.

(d) For purposes of determining compliance with this Section 6.01:

(i) in the event that any Indebtedness meets the criteria of more than one of the categories described in clauses (i) through (iv) of Section 6.01(d), the Borrower in its sole discretion, will be permitted to classify such item of Indebtedness at the time of such incurrence in any manner that complies with this Section 6.01;

(ii) 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, or less onerous, terms, the reclassification of preferred stock of the Borrower or any Restricted Subsidiary as Indebtedness due to a change in accounting principles, and the payment of dividends on Disqualified Stock or preferred stock in the form of additional shares of the same class of Disqualified Stock or preferred stock, the accrual of dividends on Disqualified Stock or preferred stock and the accretion of the liquidation preference of Disqualified Stock or preferred stock will not be deemed to be an incurrence of Indebtedness for purposes of this Section 6.01;

(iii) Indebtedness permitted by this Section 6.01 need not be permitted solely by reference to one provision permitting such Indebtedness, but may be permitted in part by one such provision and in part by one or more other provisions of this Section 6.01 permitting such Indebtedness; and

(iv) for the purposes of determining compliance with any U.S. dollar-denominated restriction on the incurrence of Indebtedness denominated in a foreign currency, the dollar-equivalent principal amount of such Indebtedness incurred pursuant thereto shall be

calculated based on the relevant currency exchange rate in effect on the earlier of the date that such Indebtedness was incurred, in the case of term Indebtedness, or first committed, in the case of revolving credit Indebtedness; provided that if such Indebtedness is incurred to refinance other Indebtedness denominated in a foreign currency, and such refinancing would cause the applicable U.S. dollar-dominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-dominated restriction shall be deemed not to have been exceeded so long as the principal amount of such refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced. Notwithstanding any other provision of this Section 6.01, the maximum amount of Indebtedness that the Borrower or any Restricted Subsidiary may incur pursuant to this Section 6.01 shall not be deemed to be exceeded solely as a result of fluctuations in the exchange rate of currencies. The principal amount of any Indebtedness incurred to refinance other Indebtedness, if incurred in a different currency from the Indebtedness being refinanced, shall be calculated based on the currency exchange rate applicable to the currencies in which such refinancing Indebtedness is denominated that is in effect on the date of such refinancing.

SECTION 6.02. LIMITATION ON LIENS. The Borrower and the Restricted Subsidiaries shall not directly or indirectly, create, incur, assume or otherwise cause or suffer to exist or become effective any Lien of any kind on the Collateral (other than Collateral Permitted Liens).

The Borrower and the Restricted Subsidiaries shall not, directly or indirectly: (a) consolidate or merge with or into another Person (whether or not the Borrower or such Restricted Subsidiary is the surviving corporation); or (b) sell, assign, transfer, convey, lease or otherwise dispose of all or substantially all of the properties or assets of the Borrower and the Restricted Subsidiaries taken as a whole, in one or more related transactions, to another Person; provided that, any Restricted Subsidiary may consolidate with, merge into, sell, assign, convey, lease or otherwise transfer all or part of its properties and assets to the Borrower or another Restricted Subsidiary.

The foregoing shall constitute Events of Default whatever the reason for any such Event of Default and whether it is voluntary or involuntary or is effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body.

SECTION 7.02. ACCELERATION.

(a) In the case of an Event of Default specified in clause (f) of Section 7.01, the Commitment shall automatically terminate, and the principal of the Loans then unpaid, together with accrued and unpaid interest thereon and all fees and other Obligations of the Borrower and the Guarantors accrued hereunder and under the other Loan Documents, shall automatically become due and payable in cash, without presentment, demand, protest or other notice of any kind, all of which are hereby waived by the Borrower and the Guarantors.

(b) If any other Event of Default occurs and is continuing, any Electing Lender may, by notice to the Borrower, take either or both of the following actions, at the same or different times: terminate the Commitment of such Electing Lender and declare the portion of the Loans owed to such Electing Lender then unpaid to be due and payable in whole (or in part, in which case any principal not so declared to be due and payable may thereafter be declared to be due and payable), and thereupon the principal of such Loans so declared to be due and

payable, together with accrued and unpaid interest thereon and all fees and other Obligations of the Borrower and the Guarantors owed to such Electing Lender and accrued hereunder and under the other Loan Documents, shall become due and payable in cash immediately, without presentment, demand, protest or other notice of any kind, all of which are hereby waived by the Borrower and the Guarantors. In the case of an Event of Default specified in clause (f) of Section 7.01 or any declaration specified in clause (b) of this Section 7.02, the Lenders or any Electing Lender (as the case may be) may pursue any available remedy to collect the payment of principal of or interest on the Loans or to enforce the performance of any provision of this Agreement and any other Loan Document.

SECTION 7.03. WAIVER OF DEFAULTS. At any time prior to the date of any acceleration pursuant to Section 7.02(a) or (b), the Required Lenders may, on behalf of the Lenders, waive any existing Default or Event of Default and its consequences under this Agreement or any other Loan Document. When a Default or Event of Default is waived, it is deemed cured and ceases to exist and shall be deemed to have been cured and waived for every purpose under this Agreement and the other Loan Documents, but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any consequent right of any Lender or the Collateral Agent.

SECTION 7.04. RIGHTS AND REMEDIES CUMULATIVE. No right or remedy conferred or reserved to Collateral Agent or any Lender under this Agreement or any other Loan Document is intended to be exclusive of any other right or remedy, and all such rights and remedies are, to the extent permitted by law, cumulative and in addition to every other right and remedy hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or exercise of any right or remedy hereunder, or otherwise, will not prevent the concurrent or subsequent assertion or exercise of any other right or remedy.

SECTION 7.05. DELAY OR OMISSION NOT WAIVER. No delay or omission of any Lender to exercise any right or remedy accruing upon any Event of Default will impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article VII or by law to the Electing Lenders or to the Lenders, as the case may be, may be exercised from time to time, and as often as may be deemed expedient, by the Electing Lenders, the Required Lenders or by the Lenders, as the case may be.

ARTICLE VIII

GUARANTEES

SECTION 8.01. GUARANTEES.

(a) Each Guarantor hereby jointly and severally unconditionally and irrevocably guarantees, as a primary obligor and not merely as a surety, to each Lender and to the Collateral Agent and their respective successors and assigns (i) the full and punctual payment of principal of, premium, if any, and interest on all Obligations of the Borrower arising under this Agreement, the Notes and the other Loan Documents, when due, whether at maturity, by acceleration, by required pre-payment or otherwise, subject to any applicable grace period and (ii) the full and punctual performance and observance within applicable grace periods of all other

obligations, covenants, agreements and conditions of the Borrower, whether for expenses, indemnification or otherwise under this Agreement (all of the foregoing being hereinafter collectively referred to as the “GUARANTEED OBLIGATIONS”). Each Guarantor further agrees that the Guaranteed Obligations may be extended or renewed, in whole or in part, without notice or further assent from each such Guarantor, and that each such Guarantor shall remain bound under this Article VIII notwithstanding any extension or renewal of any Guaranteed Obligation.

(b) Each Guarantor waives presentation to, demand of, payment from and protest to the Borrower of any of the Guaranteed Obligations and also waives notice of protest for nonpayment. Each Guarantor waives notice of any default under the Loans or the Guaranteed Obligations. The obligations of each Guarantor hereunder shall not be affected by (i) the failure of any Lender or the Collateral Agent to assert any claim or demand or to enforce any right or remedy against the Borrower or any other Person under this Agreement, any of the other Loan Documents or any other agreement or otherwise; (ii) any extension or renewal of any Guaranteed Obligations; (iii) any rescission, waiver, amendment or modification of any of the terms or provisions of this Agreement, any of the other Loan Documents or any other agreement; (iv) the release of any security held by any Lender or the Collateral Agent for the Guaranteed Obligations or any of them; (v) the failure of any Lender or the Collateral Agent to exercise any right or remedy against any other guarantor of the Guaranteed Obligations; or (vi) any change in the ownership of such Guarantor, except as provided in Section 6.03.

(c) Each Guarantor further agrees that its Guarantee herein constitutes a Guarantee of payment, performance and compliance when due (and not a guarantee of collection) and waives any right to require that any resort be had by any Lender or the Collateral Agent to any security held for payment of the Guaranteed Obligations. Each Guarantor irrevocably waives acceptance hereof, presentment, demand, protest and any notice not provided for herein, as well as any requirement that at any time any action be taken by any Person against the Borrower or any other Person. The obligations of each Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason, including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Guaranteed Obligations or otherwise. Without limiting the generality of the foregoing, the obligations of each Guarantor herein shall not be discharged or impaired or otherwise affected by the failure of any Lender or the Collateral Agent to assert any claim or demand or to enforce any remedy under this Agreement, any of the other Loan Documents or any other agreement, by any waiver or modification of any thereof, by any default, failure or delay, willful or otherwise, in the performance of the Guaranteed Obligations, or by any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of any Guarantor or would otherwise operate as a discharge of any Guarantor as a matter of law or equity.

(d) Each Guarantor further agrees that its Guarantee herein shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal of or interest on any Guaranteed Obligation is rescinded or must otherwise be restored by any Lender or the Collateral Agent upon the bankruptcy or reorganization of the Borrower or otherwise.

(e) In furtherance of the foregoing and not in limitation of any other right which any Lender or the Collateral Agent has at law or in equity against any Guarantor by virtue hereof, upon the failure of the Borrower to pay the principal of or premium, if any, or interest on any Guaranteed Obligation when and as the same shall become due, whether at maturity, by acceleration, by required pre-payment or otherwise, or to perform or comply with any other Guaranteed Obligation, each Guarantor hereby promises to and shall, upon receipt of written demand by the Collateral Agent, forthwith pay, or cause to be paid, in cash, to the Lenders or the Collateral Agent an amount equal to the sum of (i) the unpaid principal amount of such Guaranteed Obligations, (ii) accrued and unpaid interest or premium, if any, on such Guaranteed Obligations (but only to the extent not prohibited by law) and (iii) all other monetary Guaranteed Obligations of the Borrower to the Lenders and the Collateral Agent.

(f) Each Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Lenders in respect of any Guaranteed Obligations guaranteed hereby until payment in full of all Guaranteed Obligations. Each Guarantor further agrees that, as between it, on the one hand, and the Lenders and the Collateral Agent, on the other hand, (x) the maturity of the Guaranteed Obligations guaranteed hereby may be accelerated as provided in Article VII for the purposes of any Guarantee herein, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Guaranteed Obligations guaranteed hereby, and (y) in the event of any declaration of acceleration of such Guaranteed Obligations as provided in Article VII, such Guaranteed Obligations (whether or not due and payable) shall forthwith become due and payable by such Guarantor for the purposes of this Section.

SECTION 8.02. LIMITATION ON LIABILITY. Any term or provision of this Agreement to the contrary notwithstanding, the maximum aggregate amount of the obligations guaranteed hereunder by any Guarantor shall not exceed the maximum amount that can be guaranteed without rendering this Agreement and the respective Guarantee, as it relates to such Guarantor, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally.

SECTION 8.03. SUCCESSORS AND ASSIGNS. This Article VIII shall be binding upon each Guarantor and its successors and assigns and shall inure to the benefit of the successors and assigns of the Collateral Agent and the Lender and, in the event of any transfer or assignment of rights by any Lender or the Collateral, the rights and privileges conferred upon such party in this Agreement and the other Loan Documents shall automatically extend to and be vested in such transferee or assignee, all subject to the terms and conditions of this Agreement.

SECTION 8.04. EXECUTION AND DELIVERY OF THE GUARANTEE. The execution by each Guarantor of this Agreement (or a joinder agreement substantially in form of Exhibit E attached hereto in accordance with Section 5.16(a)) evidences the Guarantee of such Guarantor.

ARTICLE IX

THE COLLATERAL AGENT

SECTION 9.01. APPOINTMENT. Each Lender hereby appoints U.S. Bank National Association as its Collateral Agent under and for purposes of each Loan Document, and hereby authorizes the Collateral Agent to act on behalf of such Lender under each Loan Document and, in the absence of other written instructions from the Lenders pursuant to the terms of the Loan Documents received from time to time by the Collateral Agent, to exercise such powers hereunder and thereunder as are specifically delegated to or required of the Collateral Agent by the terms hereof and thereof, together with such powers as may be incidental thereto. Each Lender hereby irrevocably designates and appoints the Collateral Agent as the agent of such Lender. Notwithstanding any provision to the contrary elsewhere in this Agreement, the Collateral Agent shall not have any duties or responsibilities, except those expressly set forth herein, or any fiduciary relationship with any Lender, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement or any other Loan Document or otherwise exist against the Collateral Agent.

SECTION 9.02. DELEGATION OF DUTIES. The Collateral Agent may execute any of its duties under this Agreement and the other Loan Documents by or through agents or attorneys-in-fact and shall be entitled to advice of counsel concerning all matters pertaining to such duties. The Collateral Agent shall not be responsible for the negligence or misconduct of any agents or attorneys in-fact selected by it with reasonable care.

SECTION 9.03. EXCULPATORY PROVISIONS. Neither the Collateral Agent nor any of its respective officers, directors, employees, agents, attorneys-in-fact or Affiliates shall be (a) liable for any action lawfully taken or omitted to be taken by it or such Person under or in connection with this Agreement or any other Loan Document (except to the extent that any of the foregoing are found by a final and nonappealable decision of a court of competent jurisdiction to have resulted from its or such Person’s own gross negligence or willful misconduct) or (b) responsible in any manner to any of the Lenders for any recitals, statements, representations or warranties made by TerreStar Parent, the Borrower, the FCC License Subsidiary or any other Guarantor or any officer thereof contained in this Agreement or any other Loan Document or in any certificate, report, statement or other document referred to or provided for in, or received by the Collateral Agent under or in connection with, this Agreement or any other Loan Document or for the value, validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement or any other Loan Document or for any failure of TerreStar Parent, the Borrower, the FCC License Subsidiary or any other Guarantor or other Person to perform its obligations hereunder or thereunder. The Collateral Agent shall not be under any obligation to any Lender to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Agreement or any other Loan Document, or to inspect the properties, books or records of TerreStar Parent, the Borrower, the FCC License Subsidiary or any other Guarantor.

SECTION 9.04. RELIANCE BY THE COLLATERAL AGENT. The Collateral Agent shall be entitled to rely, and shall be fully protected in relying, upon any instrument, writing, resolution, notice, consent, certificate, affidavit, letter, telecopy, telex or teletype message,

statement, order or other document or conversation believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons and upon advice and statements of legal counsel (including counsel to the Borrower and the Guarantors), independent accountants and other experts selected by the Collateral Agent. The Collateral Agent may deem and treat the payee of any note as the owner thereof for all purposes unless a written notice of assignment, negotiation or transfer thereof shall have been filed with the Collateral Agent. The Collateral Agent shall be fully justified in failing or refusing to take any action under this Agreement or any other Loan Document unless it shall first receive such advice or concurrence of the Required Lenders (or, if so specified by this Agreement, all or other requisite Lenders) as it deems appropriate or it shall first be indemnified to its satisfaction by the Lenders against any and all liability and expense that may be incurred by it by reason of taking or continuing to take any such action. The Collateral Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement and the other Loan Documents in accordance with a request of the Required Lenders (or, if so specified by this Agreement, all Lenders), and such request and any action taken or failure to act pursuant thereto shall be binding upon all the Lenders and all future holders of the Loans.

SECTION 9.05. NOTICE OF DEFAULT. The Collateral Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default hereunder unless the Collateral Agent has received notice from a Lender or the Borrower referring to this Agreement, describing such Default or Event of Default and stating that such notice is a “notice of default”. In the event that the Collateral Agent receives such a notice, the Collateral Agent shall give notice thereof to the other Lenders. The Collateral Agent shall take such action with respect to such Default or Event of Default as shall be reasonably directed by the Required Lenders (or, if so specified by this Agreement, all Lenders or any other instructing group of Lenders specified by this Agreement); provided, that unless and until the Collateral Agent shall have received such directions, the Collateral Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as the Collateral Agent shall deem advisable in the best interests of the Lenders.

SECTION 9.06. NON-RELIANCE ON THE COLLATERAL AGENTS AND OTHER LENDERS. Each Lender expressly acknowledges that neither the Collateral Agent nor any of its respective officers, directors, employees, agents, attorneys-in-fact or Affiliates have made any representations or warranties to it and that no act by the Collateral Agent hereafter taken, including any review of the affairs of the Borrower, any Guarantor or any their Affiliates, shall be deemed to constitute any representation or warranty by the Collateral Agent to any Lender. Each Lender represents to the Collateral Agent that it has, independently and without reliance upon the Collateral Agent or any other Lender, and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, operations, property, financial and other condition and creditworthiness of the Borrower, the Guarantors and their Affiliates and made its own decision to make its Loans hereunder and enter into this Agreement. Each Lender also represents that it will, independently and without reliance upon the Collateral Agent or any other Lender, and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Agreement and the other Loan Documents, and to make such investigation as it deems necessary to inform itself as to the business, operations, property, financial and other condition and creditworthiness of the Borrower, the Guarantors and

their Affiliates. Except for notices, reports and other documents expressly required to be furnished to the Lenders by the Collateral Agent hereunder, the Collateral Agent shall not have any duty or responsibility to provide any Lender with any credit or other information concerning the business, operations, property, condition (financial or otherwise), prospects or creditworthiness of the Borrower, any Guarantor, or any their Affiliates that may come into the possession of the Collateral Agent or any of its officers, directors, employees, agents, attorneys-in-fact or Affiliates.

SECTION 9.07. INDEMNIFICATION. The Lenders agree to indemnify the Collateral Agent in its capacity as such (to the extent not reimbursed by the Borrower and the Guarantors and without limiting the obligation of the Borrower and the Guarantors to do so), ratably according to their respective Commitments in effect on the date on which indemnification is sought under this Section 9.07, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind whatsoever that may at any time (whether before or after the payment of the Loans) be imposed on, incurred by or asserted against the Collateral Agent in any way relating to or arising out of, the Commitments, this Agreement, any of the other Loan Documents, or any documents contemplated by or referred to herein or therein or the transactions contemplated hereby or thereby or any action taken or omitted by the Collateral Agent under or in connection with any of the foregoing; provided, that no Lender shall be liable for the payment of any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements that are found by a final and nonappealable decision of a court of competent jurisdiction to have resulted from the Collateral Agent’s gross negligence or willful misconduct. The agreements in this Section 9.07 shall survive the payment of the Loans and all other amounts payable hereunder.

SECTION 9.08. SUCCESSOR COLLATERAL AGENTS. The Collateral Agent may resign as Collateral Agent upon twenty (20) days’ notice to the Lenders and the Borrower. If the Collateral Agent shall resign as the Collateral Agent in such capacity under this Agreement and the other Loan Documents, then the Required Lenders shall appoint from among the Lenders a successor collateral agent, which successor collateral agent shall (unless an Event of Default shall have occurred and be continuing) be subject to approval by the Borrower (which approval shall not be unreasonably withheld or delayed), whereupon such successor collateral agent shall succeed to the rights, powers and duties of the Collateral Agent in its applicable capacity, and the term “Collateral Agent” shall mean such successor agent effective upon such appointment and approval, and the former Collateral Agent’s rights, powers and duties as Collateral Agent in its applicable capacity shall be terminated, without any other or further act or deed on the part of such former Collateral Agent or any of the parties to this Agreement or any holders of the Loans. If no applicable successor collateral agent has accepted appointment as the Collateral Agent in its applicable capacity by the date that is twenty (20) days following such retiring Collateral Agent’s notice of resignation, such retiring Collateral Agent’s resignation shall nevertheless thereupon become effective and the Lenders shall assume and perform all of the duties of the Collateral Agent hereunder until such time, if any, as the Required Lenders appoint a successor agent as provided for above. After the retiring Collateral Agent’s resignation as the Collateral Agent or the Collateral Agent, as applicable, the provisions of this Article IX shall inure to its benefit as to any actions taken or omitted to be taken by it while it was the Collateral Agent under this Agreement and the other Loan Documents.

SECTION 9.09. THE COLLATERAL AGENT GENERALLY. Except as expressly set forth herein, the Collateral Agent shall not have any duties or responsibilities hereunder in its capacity as such.

SECTION 9.10. AGENCY FOR PERFECTION. Collateral Agent hereby appoints each other Lender as its agent (and each Lender hereby accepts such appointment) for the purpose of perfecting the Collateral Agent’s Liens in assets which, in accordance with Article 8 or Article 9, as applicable, of the Uniform Commercial Code of any applicable state can be perfected only by possession or control. Should any Lender obtain possession or control of any such Collateral, such Lender shall notify Collateral Agent thereof, and, promptly upon Collateral Agent’s request therefor shall deliver possession or control of such Collateral to Collateral Agent or in accordance with Collateral Agent’s instructions.

SECTION 10.02. WAIVERS; AMENDMENTS.

(a) NO DEEMED WAIVERS; REMEDIES CUMULATIVE. No failure or delay by Collateral Agent or any Lender in exercising any right or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of Collateral Agent and the Lenders hereunder are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of this Agreement or consent to any departure by the Borrower therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) of this Section, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan shall not be construed as a waiver of any Default or Event of Default, regardless of whether Collateral Agent or any Lender may have had notice or knowledge of such Default or Event of Default at the time.

(b) AMENDMENTS.

(i) Subject to the provisions of Section 10.05, neither this Agreement nor any provision hereof may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by the Borrower and the Required Lenders; provided that no such amendment or waiver shall (A) increase any Commitment of any Lender without the prior written consent of such Lender, (B) reduce the principal of, or rate of interest on, any Loan or any fees specified herein, due to a Lender without the prior written consent of each Lender directly affected thereby, (C) postpone or otherwise change the date fixed for any payment of principal of, or interest on, any Loan or any fees hereunder due to a Lender or for any termination of any Commitment of a Lender, without the prior written consent of each Lender directly affected thereby, (D) decrease any amount payable to a Lender pursuant to the provisions of Article II hereof, without the prior written consent of each Lender directly affected thereby, (E) release the Borrower from its obligations hereunder or release a Guarantor from its obligations under the Subsidiary Guarantee (except as expressly permitted hereby or thereby), without the prior written consent of all of the Lenders, (F) release Collateral from the Liens created by the Security Documents (except as expressly permitted hereby or thereby), without the prior written consent of all of the Lenders, (G) amend or modify the provisions of this Section 10.02(b), without the prior written consent of all of the Lenders, or (H) amend the definition of “Required Lenders,” without the prior written consent of all of the Lenders. No such amendment, modification, waiver or consent shall adversely affect the rights and obligations of the Collateral Agent, if any, without their prior written consent. Collateral Agent, each Lender and Participant shall be bound by any amendment, modification, waiver or consent authorized as provided herein (whether or not any applicable Note shall have been marked to indicate such amendment, modification, waiver or consent); and any consent by any holder of a

Loan, a Commitment or a Note shall bind any Person subsequently acquiring such Loan, Commitment or Note (whether or not any applicable Note is so marked).

(ii) Notwithstanding the foregoing provisions of this Section 10.02(b), in connection with any issue arising under this Agreement or any Loan Document, any Lender may, in its sole discretion, request to receive material, non-public information relating to the Borrower or its business and (A) use such information in connection with such issue, (B) disregard such information and use only Information in connection with such issue or (C) waive its rights with respect to such issue, in which case, such Lender will agree to vote and will be deemed to have voted its Commitment under this Agreement pro rata in accordance with the percentage of the Commitment voted in favor of, and the percentage of the Commitment voted against, any such issue.

SECTION 10.03. EXPENSES; INDEMNITY; DAMAGE WAIVER; COMMITMENT FEE.

(a) COSTS AND EXPENSES. The Borrower shall pay (i) all reasonable expenses incurred by Collateral Agent, any Lender and their respective Affiliates (including the fees, charges and disbursements of their counsel) in connection with the preparation of this Agreement and the other Loan Documents, (ii) all reasonable expenses incurred by Collateral Agent, any Lender and their respective Affiliates, including the reasonable fees, charges and disbursements of their counsel, in connection with the administration of this Agreement and the other Loan Documents or any amendments, modifications or waivers of the provisions hereof or thereof, (iii) all reasonable expenses incurred by Collateral Agent, any Lender and their respective Affiliates, including the fees, charges and disbursements of any counsel therefor, in connection with the enforcement or protection of its rights in connection with this Agreement and the other Loan Documents, including its rights under this Section, or in connection with the Loans made hereunder, including in connection with any workout, restructuring or negotiations in respect thereof and (iv) all taxes, assessments and other charges and reasonable costs and expenses incurred in connection with any filing, registration, recording or perfection of any security interest contemplated by any Loan Document or any other document referred to therein.

(b) INDEMNIFICATION BY THE BORROWER. The Borrower shall indemnify Collateral Agent, each Lender and each Related Party of the Lender (each such Person being called an “INDEMNITEE”) against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses, including the fees, charges and disbursements of any counsel for any Indemnitee, incurred by or asserted against any Indemnitee arising out of, in connection with, or as a result of (i) the execution or delivery of this Agreement or any agreement or instrument contemplated hereby, the performance by the parties hereto of their respective obligations hereunder or the consummation of the Transactions or any other transactions contemplated hereby, (ii) any Loan or the use of the proceeds therefrom, (iii) any actual or alleged presence or release of Hazardous Materials on or from any property owned or operated by the Borrower or any Environmental Liability related in any way to the Borrower, or (iv) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory and regardless of whether any Indemnitee is a party thereto; provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses are

determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of such Indemnitee.

(c) WAIVER OF CONSEQUENTIAL DAMAGES, ETC. To the extent permitted by applicable law, the Borrower shall not assert, and hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement or any agreement or instrument contemplated hereby, the Transactions, any Loan or the use of the proceeds thereof.

(d) PAYMENTS. All amounts due under this Section shall be payable upon written demand therefor.

SECTION 10.04. SUCCESSORS AND ASSIGNS.

(a) ASSIGNMENTS GENERALLY. The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, except that the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder or under the other Loan Documents without the prior written consent of the Lenders (and any attempted assignment or transfer by the Borrower without such consent shall be null and void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their permitted successors and assigns and, to the extent expressly contemplated hereby, the Related Parties of any Lender) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) ASSIGNMENT BY THE LENDERS. Any Lender may assign all or a portion of the Loans and of its rights, duties and obligations under this Agreement (including all or a portion of the Commitment) and the other Loan Documents to any other Person without the prior written consent of the Borrower, provided that (i) the aggregate outstanding principal amount of the Loans (or the Commitment) subject to any such assignment shall be $5,000,000 or a whole multiple thereof, unless such assignment is of such Lender’s entire interest and (ii) as long as no Default of the type described in clauses (i) or (ii) of Section 7.01 or Event of Default of the type described in clause (f) of Section 7.01 shall have occurred and be continuing at such time, no such assignment shall be made to any Person other than an Eligible Assignee without the Borrower’s prior written consent. Upon execution and delivery by the assignee to the Borrower of an instrument in writing pursuant to which such assignee agrees to become a “Lender” hereunder and Borrower’s consent, if applicable, the assignee shall have the obligations, rights and benefits hereunder of the assigning Lender in respect of the Commitment (or portion thereof) and Loan(s) theretofore held by such Lender, and the assigning Lender shall be released from the Commitment (or portion thereof) so assigned. For purposes of this Section 10.04(b), the term “ELIGIBLE ASSIGNEE” means (A) a Lender or any Affiliate thereof, (B) any bank, trust company, savings and loan association or other financial institution, any pension plan, any investment company, any insurance company or similar financial institution or entity organized under the laws of (x) the United States, or any state thereof, or (y) any other country which is a member of the OECD, or a political subdivision of any such country, provided that such bank is acting through a branch or agency located either in the country in which it is organized, another country which is also an OECD member or the Cayman

Islands and (C) any Person (other than a natural person) that is or will be engaged in making, purchasing, holding or otherwise investing in commercial loans and similar extensions of credit and has assets under management of at least $500,000,000. “ELIGIBLE ASSIGNEE” shall not include a competitor of the Borrower.

(c) The Borrower hereby acknowledges and agrees that in connection with any assignment by any Lender of less than all of the Loans and the Commitment, the Lenders may employ at the expense of the Lenders an administrative agent to act on behalf of the Lenders under this Agreement and the other Loan Documents, and the Borrower agrees to customary and reasonable modifications to this Agreement and the other Loan Documents to reflect the duties and responsibilities of such agent, acting on behalf of the Lenders, and multiple Lenders. For the avoidance of doubt, it is understood and agreed that in no event shall the amount of the Commitment, the rate of interest on the Loans, the Maturity Date, the definition of Required Lenders, the representations or warranties of the Borrower, the negative covenants or the prepayment provisions of the Agreement be modified in connection with the employment of such administrative agent.

(d) In connection with any assignment by any Lender (other than assignments requiring the Borrower’s approval), the assigning Lender shall provide notice of such assignment to the Borrower, and the Borrower hereby acknowledges and agrees to maintain a register of all assignments by the Lenders.

(e) PARTICIPATIONS. Any Lender may, without the consent of the Borrower, sell participations to one or more banks or other entities (a “PARTICIPANT”) in all or a portion of such Lender’s rights and obligations under this Agreement and the other Loan Documents (including all or a portion of the Loans and the Commitment); provided that (i) such Lender’s obligations under this Agreement and the other Loan Documents shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrower shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement and the other Loan Documents. Any agreement or instrument pursuant to which any Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and the other Loan Documents and to approve any amendment, modification or waiver of any provision of this Agreement or any other Loan Document. In no event shall the selling Lender agree with the Participant to take or refrain from taking any action under this Agreement or under any other Loan Document except that such Lender may agree with the Participant that it will not, without the consent of the Participant, agree to (1) increase or extend the term, or extend the time or waive any requirement for the reduction, termination or prepayment, of the Loans, (2) extend the date fixed for the payment of principal of or interest on the Loans, (3) reduce the amount of any such payment of principal or any premium payable hereunder, (4) reduce the rate at which interest is payable on any amount under this Agreement, or reduce any fee or other amount payable to the Participant to a level below the rate at which the Participant is entitled to receive such interest or fee, (5) alter the rights or obligations of the Borrower to prepay the Loans, or (6) release any portion of the Collateral or terminate any Lien under the Security Documents prior to the payment in full of the Loan and all amounts required to be paid by the Borrower to Collateral Agent or any Lender under the Loan Documents except as contemplated in the Security Documents.

(f) LIMITATIONS ON RIGHTS OF PARTICIPANTS. A Participant shall not be entitled to receive any greater payment under Section 2.08 than the selling Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower’s prior written consent.

SECTION 10.05. THE BUY OUT.

(a) One or more Lenders may (but shall not be obligated to) cause the assignment to such Lender(s) or their designee (each, a “BUYING LENDER”), by any other Lender (each, a “SELLING LENDER”), of all right, title and interest in, to, arising under, or in respect of all Obligations of the Borrower and the Guarantors hereunder and under the other Loan Documents owed to the Selling Lenders under the Loan Documents upon written notice from the Buying Lenders to the Selling Lenders given at any time after the date on which the Selling Lenders (i) reject any waiver, amendment or modification of, or deny any departure by the Borrower from, any provision of this Agreement or any Loan Document or (ii) accelerate pursuant to Section 7.02(b) or any automatic acceleration pursuant to Section 7.02(a).

(b) Such assignment shall be effected not later than ten (10) Business Days following the giving of such notice upon the execution by the Buying Lenders and the Selling Lenders of an instrument in writing pursuant to which the Buying Lenders agree to assume all Obligations owed to the Selling Lenders under the Loan Documents in exchange for the payment at par, in immediately available funds, of the amount of the Obligations owed to each such Selling Lenders as of the date on which such assignment is made, at which time the Selling Lenders shall be released from all obligations and duties under the Loan Documents. The assignments by the Selling Lenders pursuant to this Section 10.05 shall be without recourse or warranty of any kind.

SECTION 10.06. SURVIVAL. All covenants, agreements, representations and warranties made by the Borrower herein and in the certificates or other instruments delivered in connection with or pursuant to this Agreement shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of this Agreement and the making of each Loan, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Lenders may have had notice or knowledge of any Default or Event of Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement is outstanding and unpaid and so long as the Commitment has not expired or terminated. The provisions of Sections 2.08, 2.09 and 10.03 shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans, the expiration or termination of the Commitment or the termination of this Agreement or any provision hereof.

SECTION 10.07. COUNTERPARTS; INTEGRATION; EFFECTIVENESS. This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement and the other Loan Documents constitute the entire contract between the parties relating to the subject matter hereof and thereof and supersede

any and all previous agreements and understandings, oral or written, relating to the subject matter hereof and thereof. Except as provided in Article IV, this Agreement shall become effective when it shall have been executed by Collateral Agent and the Lenders and when Collateral Agent and the Lenders shall have received a counterpart hereof bearing the signature of the Borrower, and thereafter shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns.

SECTION 10.08. SEVERABILITY. Any provision of this Agreement held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.
