(b) Consolidated Interest Expense;

(d) impairment charges, including the write-down of Investments;

In addition to and without limitation of the foregoing, for purposes of this definition, “Consolidated Cash Flow Available for Fixed Charges” and “Consolidated Fixed Charges” shall be calculated after giving effect (i) to the cost of any compensation, remuneration or other benefit paid or provided to any employee, consultant, Affiliate or equity owner of the entity involved in any Asset Acquisition to the extent such costs are eliminated or reduced (or public announcement has been

-5-

made of the intent to eliminate or reduce such costs) prior to the date of such calculation and not replaced; and (ii) on a pro forma basis for the period of such calculation, to any Asset Sales or other dispositions or Asset Acquisitions, investments, mergers, consolidations and discontinued operations (as determined in accordance with GAAP) occurring during the Four Quarter Period or any time subsequent to the last day of the Four Quarter Period and on or prior to the Transaction Date, as if such Asset Sale or other disposition or Asset Acquisition (including the incurrence or assumption of any such Acquired Debt), investment, merger, consolidation or disposed operation occurred on the first day of the Four Quarter Period. For purposes of this definition, pro forma calculations shall be made in accordance with Article 11 of Regulation S-X promulgated under the Securities Act.

Furthermore, in calculating “Consolidated Fixed Charges” for purposes of determining the denominator (but not the numerator) of this “Consolidated Fixed Charge Coverage Ratio”:

(a) interest on outstanding Debt determined on a fluctuating basis as of the Transaction Date and which will continue to be so determined thereafter shall be deemed to have accrued at a fixed rate per annum equal to the rate of interest on such Debt in effect on the Transaction Date; and

(b) if interest on any Debt actually incurred on the Transaction Date may optionally be determined at an interest rate based upon a factor of a prime or similar rate, a eurocurrency interbank offered rate, or other rates, then the interest rate in effect on the Transaction Date will be deemed to have been in effect during the Four Quarter Period.

If such Person or any of its Restricted Subsidiaries directly or indirectly Guarantees Debt of a third Person, the above clause shall give effect to the incurrence of such Guaranteed Debt as if such Person or such Subsidiary had directly incurred or otherwise assumed such Guaranteed Debt.

“Consolidated Fixed Charges” means, with respect to any Person for any period, the sum of, without duplication, the amounts for such period of:

(a) Consolidated Interest Expense; and

(b) the product of (i) all dividends and other distributions paid or accrued during such period in respect of Redeemable Capital Interests of such Person and its Restricted Subsidiaries (other than dividends paid in Qualified Capital Interests), times (ii) a fraction, the numerator of which is one and the denominator of which is one minus the then current combined federal, state and local statutory tax rate of such Person, expressed as a decimal.

“Consolidated Income Tax Expense” means, with respect to any Person for any period, the provision for federal, state, local and foreign income taxes of such Person and its Restricted Subsidiaries for such period as determined on a consolidated basis in accordance with GAAP paid or accrued during such period, including any penalties and interest related to such taxes or arising from any tax examinations, to the extent the same were deducted in computing Consolidated Net Income.

(ii) the interest component of Capital Lease Obligations paid, accrued and/or scheduled to be paid or accrued by such Person and its Restricted Subsidiaries during such period determined on a consolidated basis in accordance with GAAP; and

(iii) all capitalized interest of such Person and its Restricted Subsidiaries for such period;

less interest income of such Person and its Restricted Subsidiaries for such period; provided, however, that Consolidated Interest Expense will exclude (I) the amortization or write-off of Debt issuance costs and deferred financing fees, commissions, fees and expenses and (II) any expensing of interim loan commitment and other financing fees.

“Consolidated Net Income” means, with respect to any Person for any period, the consolidated net income (or loss) of such Person and its Restricted Subsidiaries for such period as determined in accordance with GAAP, adjusted, to the extent included in calculating such net income, by:

(iv) the net income (loss) from any disposed or discontinued operations or any net gains or losses on disposed or discontinued operations, on an after-tax basis;

(v) solely for purposes of determining the amount available for Restricted Payments under clause (c) of the first paragraph of Section 4.7, the net income of any Restricted Subsidiary (other than a Guarantor) or such Person to the extent that the declaration of dividends or similar distributions by that Restricted Subsidiary of that income is not at the time permitted, directly or indirectly, by operation of the terms of its charter or any agreement, instrument, judgment, decree, order, statute, rule or governmental regulations applicable to that Restricted Subsidiary or its stockholders; provided that for the avoidance of doubt, Consolidated Net Income shall be increased in amounts equal to the amounts of cash actually received;

(vi) any gain or loss realized as a result of the cumulative effect of a change in accounting principles;

(vii) any fees and expenses paid in connection with the issuance of the Notes;

(viii) non-cash compensation expense incurred with any issuance of equity interests to an employee of such Person or any Restricted Subsidiary;

(ix) any net after-tax gains or losses attributable to the early extinguishment or conversion of Debt;

(xvi) any expenses, charges or losses that are covered by indemnification or other reimbursement provisions in connection with any Permitted Investment or any sale, conveyance, transfer or other disposition of assets permitted under this Indenture, to the extent actually reimbursed, or, so long as the Issuer has made a determination that a reasonable basis exists for indemnification or reimbursement and only to the extent that such amount is in fact indemnified or reimbursed within 365 days of such determination (with a deduction in the applicable future period for any amount so added back to the extent not so indemnified or reimbursed within such 365 days); and

A Note shall not be valid until authenticated by the manual signature of an authorized signatory of the Trustee. The signature shall be conclusive evidence that the Note has been authenticated under this Indenture.

The Trustee shall, upon a written order of the Issuer signed by two Officers directing the Trustee to authenticate and deliver the Notes and certifying that all conditions precedent to the issuance of the Notes contained herein have been complied with, authenticate Notes for original issue up to the aggregate principal amount stated in paragraph 4 of the Notes. The aggregate principal amount of Notes outstanding at any time may not exceed such amount except as provided in Section 2.17 hereof.

The Trustee may appoint an authenticating agent reasonably acceptable to the Issuer to authenticate Notes. Unless limited by the terms of such appointment, an authenticating agent may authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to deal with Holders or the Issuer or an Affiliate of the Issuer.

SECTION 2.3 Registrar; Paying Agent.

The Issuer shall maintain (i) an office or agency where Notes may be presented for registration of transfer or for exchange (“Registrar”) and (ii) an office or agency where Notes may be presented for payment to a Paying Agent. The Registrar shall keep a register of the Notes (the “Note Register”) and of their transfer and exchange. The Issuer may appoint one or more co-registrars and one or more additional Paying Agents; provided, however, that at all times there shall be only one Note Register. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any additional paying agent. The Issuer may change any Paying Agent or Registrar without notice to any Holder. The Issuer shall notify the Trustee in writing of the name and address of any Agent not a party to this Indenture. The Issuer or any of its Restricted Subsidiaries may act as Paying Agent or Registrar.

The Issuer shall notify the Trustee and the Holders of the name and address of any Agent not a party to this Indenture. The Issuer or any Guarantor may act as Paying Agent or Registrar. The Issuer shall enter into an appropriate agency agreement with any Agent not a party to this Indenture, which shall incorporate the provisions of Section 317(b) of the TIA. The agreement shall implement the provisions of this Indenture that relate to such Agent. The Issuer shall notify the Trustee of the name and address of any such Agent.

The Issuer initially appoints the Trustee to act as the Registrar and Paying Agent and initially appoints the Corporate Trust Office of the Trustee as the office or agency of the Company for such purposes and as the office or agency of the Company where notices and demands to or upon the Issuer in respect of the Notes and this Indenture may be served and the Trustee as the agent of the Issuer to receive such notices and demands.

The Issuer initially appoints DTC to act as the Depositary with respect to the Global Notes.

SECTION 2.4 Paying Agent to Hold Money in Trust.

The Issuer shall require each Paying Agent other than the Trustee to agree in writing that the Paying Agent shall hold in trust for the benefit of the Holders or the Trustee all money held by the Paying Agent for the payment of principal, premium, if any, or interest on the Notes, and shall notify the Trustee of any Default by the Issuer in making any such payment. While any such Default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Issuer at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Issuer or a Subsidiary) shall have no further liability for the money. If the Issuer or a Subsidiary acts as Paying Agent, it shall segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent. Upon the occurrence of events specified in Section 6.1(7) hereof, the Trustee shall serve as Paying Agent for the Notes.

SECTION 2.5 Holder Lists.

The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of all Holders and shall otherwise comply with TIA § 312(a). If the Trustee is not the Registrar, the Issuer shall furnish to the Trustee at least seven (7) Business Days before each interest payment date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of the Holders, including the aggregate principal amount of the Notes held by each Holder thereof, and the Issuer shall otherwise comply with TIA § 312(a).

SECTION 2.6 Book-Entry Provisions for Global Securities.

(a) Each Global Note constituting a Restricted Note shall (i) be registered in the name of the Depositary for such Global Notes or the nominee of such Depositary, (ii) be delivered to the Trustee as Note Custodian and (iii) bear legends as required by Section 2.6(e).

Members of, or participants in, the Depositary (“Agent Members”) shall have no rights under this Indenture with respect to any Global Note held on their behalf by the Depositary, or the Trustee as its custodian, or under the Global Note, and the Depositary may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner of such Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee, from giving effect to any written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of a Holder of any Note.

(b) Transfers of a Global Note shall be limited to transfers of such Global Note in whole, but not in part, to the Depositary, its successors or their respective nominees. Interests of Beneficial Owners (or the requesting Beneficial Owners in the case of clause (ii) immediately below) in a Global Note may be transferred in accordance with Section 2.16 and the rules and procedures of the Depositary. In addition, Certificated Notes shall be transferred to all Beneficial Owners in exchange for their beneficial interests if (i) the Depositary notifies the Company

-37-

that it is unwilling or unable to continue as Depositary for the Global Notes or the Depositary ceases to be a “clearing agency” registered under the Exchange Act and a successor depositary is not appointed by the Company within ninety (90) days of such notice or (ii) an Event of Default of which a Responsible Officer of the Trustee has actual notice has occurred and is continuing and the Registrar has received a request from the Depositary or a Beneficial Owner in a Global Note to issue such Certificated Notes.

(c) In connection with the transfer of the entire Global Note to beneficial owners pursuant to clause (b) of this Section, such Global Note shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and the Trustee shall authenticate and deliver, to each Beneficial Owner identified by the Depositary in exchange for its beneficial interest in such Global Note an equal aggregate principal amount of Certificated Notes of authorized denominations.

(iii) Each Global Note shall bear the Global Note Legend on the face thereof.

(iv) At such time as all beneficial interests in Global Notes have been exchanged for Certificated Notes, redeemed, repurchased or cancelled, all Global Notes shall be returned to or retained and cancelled by the Trustee in accordance with Section 2.11 hereof. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for Certificated Notes, redeemed, repurchased or cancelled, the principal amount of Notes represented by such Global Note shall be reduced accordingly and an endorsement shall be made on such Global Note, by the Trustee or the Note Custodian, at the direction of the Trustee, to reflect such reduction.

(i) To permit registrations of transfers and exchanges, the Issuer shall execute and the Trustee shall authenticate Global Notes and Certificated Notes at the Registrar’s request.

(iii) All Global Notes and Certificated Notes issued upon any registration of transfer or exchange of Global Notes or Certificated Notes shall be the valid obligations of the Issuer, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Global Notes or Certificated Notes surrendered upon such registration of transfer or exchange.

(iv) The Registrar shall not be required (A) to issue, to register the transfer of or to exchange Notes during a period beginning at the opening of fifteen (15) days before the day of any selection of Notes for redemption under Section 3.2 hereof and ending at the close of business on the day of selection, (B) to register the transfer of or to exchange any Note so selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part, or (C) to register the transfer of or to exchange a Note between a record date and the next succeeding interest payment date.

-40-

(v) [Reserved].

(vi) Prior to due presentment for the registration of a transfer of any Note, the Trustee, any Agent and the Issuer may deem and treat the Person in whose name any Note is registered as the absolute owner of such Note for the purpose of receiving payment of principal of and interest on such Notes and for all other purposes, and neither the Trustee, any Agent nor the Issuer shall be affected by notice to the contrary.

(vii) The Trustee shall authenticate Global Notes and Certificated Notes in accordance with the provisions of Section 2.2 hereof. Except as provided in Section 2.6(b), neither the Trustee nor the Registrar shall authenticate or deliver any Certificated Note in exchange for a Global Note.

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 and the Trustee may charge for their expenses in replacing a Note.

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

-41-

SECTION 2.8 Outstanding Notes.

The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those cancelled 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 2.8 as not outstanding. Except as set forth in Section 2.9 hereof, a Note does not cease to be outstanding because the Issuer or an Affiliate of the Issuer holds the Note.

If a Note is replaced pursuant to Section 2.7 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a bona fide purchaser.

If the principal amount of any Note is considered paid under Section 4.1 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 shall be deemed to be no longer outstanding and shall cease to accrue interest.

SECTION 2.9 Treasury Notes.

In determining whether the Holders of the required aggregate principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Issuer or by any Affiliate of the Issuer shall be considered as though not outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes shown on the register as being owned shall be so disregarded. Notwithstanding the foregoing, Notes that are to be acquired by the Issuer or an Affiliate of the Issuer pursuant to an exchange offer, tender offer or other agreement shall not be deemed to be owned by such entity until legal title to such Notes passes to such entity.

SECTION 2.10 Temporary Notes.

Until Certificated Notes are ready for delivery, the Issuer may prepare and the Trustee shall authenticate temporary Notes upon a written order of the Issuer signed by two Officers of the Issuer. Temporary Notes shall be substantially in the form of Certificated Notes but may have variations that the Issuer considers appropriate for temporary Notes. Without unreasonable delay, the Issuer shall prepare and the Trustee shall upon receipt of a written order of the Issuer signed by two Officers authenticate Certificated Notes in exchange for temporary Notes.

Holders of temporary Notes shall be entitled to all of the benefits of this Indenture.

SECTION 2.11 Cancellation.

The Issuer at any time may deliver to the Trustee for cancellation any Notes previously authenticated and delivered hereunder or which the Issuer may have acquired in any manner whatsoever, and all Notes so delivered shall be promptly cancelled by the Trustee. All Notes surrendered for registration of transfer, exchange or payment, if surrendered to any Person other

-42-

than the Trustee, shall be delivered to the Trustee. The Trustee and no one else shall cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation. Subject to Section 2.7 hereof, the Issuer may not issue new Notes to replace Notes that they have redeemed or paid or that have been delivered to the Trustee for cancellation. All cancelled Notes held by the Trustee shall be disposed of in accordance with its customary practice, and certification of their disposal delivered to the Issuer, unless by a written order, signed by an Officer of the Issuer, the Issuer shall direct that cancelled Notes be returned to it.

SECTION 2.12 Defaulted Interest.

If the Issuer defaults in a payment of interest on the Notes, it shall 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, which date shall be at the earliest practicable date but in all events at least five (5) Business Days prior to the payment date, in each case at the rate provided in the Notes and in Section 4.1 hereof. The Issuer shall fix or cause to be fixed each such special record date and payment date and shall promptly thereafter notify the Trustee of any such date. At least fifteen (15) days before the special record date, the Issuer (or the Trustee, in the name and at the expense of the Issuer) shall deliver or cause to be delivered to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid.

SECTION 2.13 Record Date.

The record date for purposes of determining the identity of Holders entitled to vote or consent to any action by vote or consent authorized or permitted under this Indenture shall be determined as provided for in TIA § 316 (c) or in accordance with the procedures of DTC for global notes.

SECTION 2.14 Computation of Interest.

Interest on the Notes shall be computed on the basis of a 360-day year comprised of twelve 30-day months.

SECTION 2.15 CUSIP Number.

The Issuer in issuing the Notes may use a “CUSIP” and/or ISIN or other similar number, and if it does so, the Company may use the CUSIP and/or ISIN or other similar number in notices of redemption or exchange as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness or accuracy of the CUSIP and/or ISIN or other similar 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 shall promptly notify the Trustee of any change in the CUSIP and/or ISIN or other similar number.

-43-

SECTION 2.16 Special Transfer Provisions.

Unless and until a Restricted Note is transferred or exchanged pursuant to an exemption under the Securities Act or under an effective shelf registration statement under the Securities Act the following provisions shall apply:

(a) Transfers to QIBs. The following provisions shall apply with respect to the registration of any proposed transfer of a Restricted Note (other than pursuant to Regulation S):

Concurrently with the issuance of such Global Notes, the Registrar shall cause the aggregate principal amount of the applicable Restricted Notes to be reduced accordingly, and the Registrar shall deliver to the Persons designated by the Holders of Restricted Notes so accepted Global Notes not bearing the Restricted Notes Legend in the appropriate principal amount.

(d) Restricted Notes Legend. Upon the transfer, exchange or replacement of Unrestricted Notes, the Registrar shall deliver Unrestricted Notes that do not bear the Restricted Notes Legend. Upon the transfer, exchange or replacement of Restricted Notes, the Registrar shall deliver only Restricted Notes that bear the Restricted Notes Legend unless the Restricted Notes Legend is no longer required by Section 2.6(e), or the Company determines and there is delivered to the Trustee an Opinion of Counsel reasonably satisfactory to the Trustee and a letter of representation of the Issuer reasonably satisfactory to the Trustee to the effect that neither such legend nor the related restrictions on transfer are required or appropriate in order to ensure that subsequent transfers of the Notes are effected in compliance with the Securities Act.

(e) General. By its acceptance of any Note bearing the Restricted Notes Legend, each Holder of such a Note acknowledges receipt of a Restricted Note with restrictions on transfer of such Note set forth in this Indenture and in the Restricted Notes Legend and agrees that it shall transfer such Note only as provided in this Indenture until such time as the Restricted Note Legend is no longer required pursuant to Section 2.6(e) and such Holder transfers such a Restricted Note for an Unrestricted Note.

In the case of Certificated Notes, a new Note in principal amount equal to the unredeemed portion of the original Note will be issued in the name of the Holder thereof upon cancellation of the original Note. In the case of Global Notes, the outstanding balance of any such Global Note shall be adjusted by the Trustee to reflect such redemption. On and after the redemption date, interest ceases to accrue on Notes or portions of them called for redemption. The Trustee shall make the selection from the Notes outstanding and not previously called for redemption and shall promptly notify the Issuer in writing of the Notes selected for redemption. The Trustee may select for redemption portions (equal to $1,000 or any integral multiple thereof) of the principal of the Notes that have denominations larger than $2,000.

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

(1) the redemption date;

(2) the Redemption Price;

(4) the name, telephone number and address of the Paying Agent;

(5) that Notes called for redemption must be surrendered to the Paying Agent to collect the Redemption Price;

(6) that, unless the Issuer defaults in making such redemption payment, interest, if any, on Notes called for redemption ceases to accrue on and after the redemption date;

(7) the paragraph of the Notes and/or Section of this Indenture pursuant to which the Notes called for redemption are being redeemed; and

(8) that no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Notes.

-47-

At the Issuer’s request, the Trustee shall give the notice of redemption in the Issuer’s name and at the Issuer’s expense; provided, however, that the Issuer shall have delivered to the Trustee at least 45 days prior to the redemption date (or such shorter period as is acceptable to the Trustee), an Officer’s Certificate requesting that the Trustee give such notice and setting forth the information to be stated in the notices as provided in the preceding paragraph. The notice sent in the manner herein provided shall be conclusively presumed to have been duly given whether or not a Holder receives such notice. In any case, failure to give such notice by electronic transmission or by mail or any defect in the notice to the Holder of any Note shall not affect the validity of the proceeding for the redemption of any other Note.

SECTION 3.4 Effect of Notice of Redemption.

Once notice of redemption is sent in accordance with Section 3.3 hereof, Notes called for redemption become irrevocably due and payable on the redemption date at the Redemption Price plus accrued and unpaid interest, if any, to such date. A notice of redemption may not be conditional.

The Trustee or the Paying Agent shall promptly return to the Issuer any money deposited with the Trustee or the Paying Agent by the Issuer in excess of the amounts necessary to pay the Redemption Price of (including any applicable premium), and accrued interest, if any, on, all Notes to be redeemed or purchased.

If Notes called for redemption or tendered in a Change of Control Offer are paid or if Issuer has deposited with the Trustee or Paying Agent money sufficient to pay the redemption or purchase price of, and unpaid and accrued interest, if any, on, all Notes to be redeemed or purchased, on and after the redemption or purchase date, interest, if any, shall cease to accrue on the Notes or the portions of Notes called for redemption or tendered and not withdrawn in a Change of Control Offer (regardless of whether certificates for such securities are actually surrendered). If a Note is redeemed or purchased on or after an interest record date but on or prior to the related interest payment date, then any accrued and unpaid interest, if any, 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 shall not be so paid upon surrender for redemption 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 4.1 hereof.

On the Purchase Date, the Company shall purchase the aggregate principal amount of Notes required to be purchased pursuant to Section 4.12 hereof (the “Offer Amount”), or if less than the Offer Amount has been tendered, all Notes tendered in response to the Offer to Purchase.

The Issuer, the Depositary or the Paying Agent, as the case may be, shall promptly (but in any case not later than three (3) Business 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, plus any accrued and unpaid interest, if any, thereon, and the Issuer shall promptly issue a new Note, and the Trustee, at the written request of the Issuer, shall authenticate and mail or deliver at the expense of the Issuer such new Note to such Holder, equal in principal amount to any unpurchased

Other than as specifically provided in this Section 3.9, any purchase pursuant to this Section 3.9 shall be made pursuant to the provisions of Sections 3.1 through 3.6 hereof.

(3) 100% of the net reduction in Investments (other than Permitted Investments), subsequent to the Issue Date, in any Person, resulting from (i) payments of interest on Debt, dividends, repayments of loans or advances, or any sale or disposition of such Investments (but only to the extent such items are not included in the calculation of Consolidated Net Income), in each case to the Company or any Subsidiary from any Person or (ii) the redesignation of an Unrestricted Subsidiary as a Restricted Subsidiary, not to exceed in the case of any Person the amount of Investments previously made by the Company or any Restricted Subsidiary in such Person subsequent to the Issue Date.

(x) the making of any Restricted Payments if, at the time of the making of such payments, and after giving effect thereto (including, without limitation, the Incurrence of any Debt to finance such payment), the Consolidated Total Leverage Ratio would not exceed 2.50 to 1.00; and

(xi) the making of any other Restricted Payments not in excess of $75.0 million in the aggregate while any Notes are outstanding.

If the Company makes a Restricted Payment which, at the time of the making of such Restricted Payment, in the good faith determination of the Company, would be permitted under the requirements of this Indenture, such Restricted Payment shall be deemed to have been made in compliance with this Indenture notwithstanding any subsequent adjustment made in good faith to the Company’s financial statements affecting Consolidated Net Income.

If any Person in which an Investment is made, which Investment constitutes a Restricted Payment when made, thereafter becomes a Restricted Subsidiary in accordance with this Indenture, all such Investments previously made in such Person shall no longer be counted as Restricted Payments for purposes of calculating the aggregate amount of Restricted Payments pursuant to clause (c) of the first paragraph under this Section 4.7, in each case to the extent such Investments would otherwise be so counted.

For purposes of this Section 4.7, if a particular Restricted Payment involves a non-cash payment, including a distribution of assets, then such Restricted Payment shall be deemed to be an amount equal to the cash portion of such Restricted Payment, if any, plus an amount equal to the Fair Market Value of the non-cash portion of such Restricted Payment.

SECTION 4.8 Limitation on Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries.

The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, cause or suffer to exist or become effective or enter into any encumbrance or restriction (other than pursuant to this Indenture or any law, rule, regulation or order) on the ability of any Restricted Subsidiary to (i) pay dividends or make any other distributions on its Capital Interests owned by the Company or any Restricted Subsidiary or pay any Debt or other obligation owed to the Company or any Restricted Subsidiary, (ii) make loans or advances to the Company or any Restricted Subsidiary thereof or (iii) transfer any of its property or assets to the Company or any Restricted Subsidiary.

-56-

However, the preceding restrictions will not apply to the following encumbrances or restrictions existing under or by reason of:

(a) any encumbrance or restriction in existence on the Issue Date, including those required by the Credit Agreement and any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings thereof; provided that the amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings, in the good faith judgment of the Company, are no more restrictive, taken as a whole, with respect to such dividend or other payment restrictions, than those contained in these agreements on the Issue Date or refinancings thereof;

(b) any encumbrance or restriction pursuant to an agreement relating to an acquisition of property, so long as the encumbrances or restrictions in any such agreement relate solely to the property so acquired (and are not or were not created in anticipation of or in connection with the acquisition thereof);

(c) any encumbrance or restriction which exists with respect to a Person that becomes a Restricted Subsidiary or merges with or into a Restricted Subsidiary of the Company on or after the Issue Date, which is in existence at the time such Person becomes a Restricted Subsidiary, but not created in connection with or in anticipation of such Person becoming a Restricted Subsidiary, and which is not applicable to any Person or the property or assets of any Person other than such Person or the property or assets of such Person becoming a Restricted Subsidiary;

(d) any encumbrance or restriction pursuant to an agreement effecting a permitted renewal, refunding, replacement, refinancing or extension of Debt issued pursuant to an agreement containing any encumbrance or restriction referred to in the foregoing clauses (a) through (c), so long as the encumbrances and restrictions contained in any such refinancing agreement are no less favorable in any material respect to the Holders than the encumbrances and restrictions contained in the agreements governing the Debt being renewed, refunded, replaced, refinanced or extended in the good faith judgment of the Company;

(e) customary provisions restricting subletting or assignment of any lease, contract, or license of the Company or any Restricted Subsidiary or provisions in agreements that restrict the assignment of such agreement or any rights thereunder;

(f) any encumbrance or restriction by reason of applicable law, rule, regulation or order;

(g) any encumbrance or restriction under this Indenture, the Notes and the Note Guarantees;

(h) any encumbrance or restriction under the sale of assets or Capital Interest, including, without limitation, any agreement for the sale or other disposition of a Subsidiary that restricts distributions by that Subsidiary pending its sale or other disposition;

-57-

(i) restrictions on cash and other deposits or net worth imposed by customers under contracts entered into the ordinary course of business;

(j) customary provisions with respect to the disposition or distribution of assets or property in Joint Venture agreements, asset sale agreements, stock sale agreements, sale leaseback agreements and other similar agreements;

(k) any instrument governing Debt or Capital Interests of a Person acquired by the Company or any of the Restricted Subsidiaries as in effect at the time of such acquisition (except to the extent such Debt or Capital Interests were 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 Debt, such Debt was permitted by the terms of this Indenture to be incurred;

(l) purchase money obligations (including Capital Lease Obligations) for property acquired in the ordinary course of business that impose restrictions on that property so acquired of the nature described in clause (iii) of the first paragraph of this Section 4.8;

(m) Liens securing Debt otherwise permitted to be incurred under this Indenture, including pursuant to Section 4.10, that limit the right of the debtor to dispose of the assets subject to such Liens;

(n) any Non-Recourse Receivable Subsidiary Indebtedness or other contractual requirements of a Receivable Subsidiary that is a Restricted Subsidiary in connection with a Qualified Receivables Transaction; provided that such restrictions apply only to such Receivable Subsidiary or the receivables and related assets described in the definition of Qualified Receivables Transaction which are subject to such Qualified Receivables Transaction; and

(o) any other agreement governing Debt entered into after the Issue Date that contains encumbrances and restrictions that are not materially more restrictive with respect to any Restricted Subsidiary than those in effect on the Issue Date with respect to that Restricted Subsidiary pursuant to agreements in effect on the Issue Date.

Nothing contained in this Section 4.8 shall prevent the Company or any Restricted Subsidiary from (i) creating, incurring, assuming or suffering to exist any Liens otherwise permitted under Section 4.10 or (ii) restricting the sale or other disposition of property or assets of the Company or any of its Restricted Subsidiaries that secure Debt of the Company or any of its Restricted Subsidiaries Incurred in accordance with Section 4.9 and Section 4.10.

SECTION 4.9 Limitation on Incurrence of Debt.

The Company will not, and will not permit any of its Restricted Subsidiaries to, Incur any Debt (including Acquired Debt); provided that the Company and any Guarantor may Incur Debt (including Acquired Debt) if, immediately after giving effect to the Incurrence of such Debt and

-58-

the receipt and application of the proceeds therefrom, (a) the Consolidated Fixed Charge Coverage Ratio of the Company and its Restricted Subsidiaries, determined on a pro forma basis as if any such Debt (including any other Debt being Incurred contemporaneously), and any other Debt Incurred since the beginning of the Four Quarter Period (provided that any Debt Incurred under the revolving portion of a credit agreement shall be calculated (x) on an annualized basis for periods prior to the one year anniversary of the Issue Date and (y) thereafter, only on such date), had been Incurred and the proceeds thereof had been applied at the beginning of the Four Quarter Period, and any other Debt repaid since the beginning of the Four Quarter Period had been repaid at the beginning of the Four Quarter Period, would be greater than 2.0:1.0, and (b) no Default or Event of Default shall have occurred and be continuing at the time or as a consequence of the Incurrence of such Debt.

If, during the Four Quarter Period or subsequent thereto and prior to the date of determination, the Company or any of its Restricted Subsidiaries shall have engaged in any Asset Sale or Asset Acquisition, Investments, mergers, consolidations, discontinued operations (as determined in accordance with GAAP) or shall have designated any Restricted Subsidiary to be an Unrestricted Subsidiary or any Unrestricted Subsidiary to be a Restricted Subsidiary, Consolidated Cash Flow Available for Fixed Charges and Consolidated Interest Expense for the Four Quarter Period shall be calculated on a pro forma basis giving effect to such Asset Sale or Asset Acquisition, Investments, mergers, consolidations, discontinued operations or designation, as the case may be, and the application of any proceeds therefrom as if such Asset Sale or Asset Acquisition or designation had occurred on the first day of the Four Quarter Period.

If the Debt which is the subject of a determination under this provision is Acquired Debt, or Debt Incurred in connection with the simultaneous acquisition of any Person, business, property or assets, or Debt of an Unrestricted Subsidiary being designated as a Restricted Subsidiary, then such ratio shall be determined by giving effect (on a pro forma basis, as if the transaction had occurred at the beginning of the Four Quarter Period) to (x) the Incurrence of such Acquired Debt or such other Debt by the Company or any of its Restricted Subsidiaries and (y) the inclusion, in Consolidated Cash Flow Available for Fixed Charges, of the Consolidated Cash Flow Available for Fixed Charges of the acquired Person, business, property or assets or redesignated Subsidiary.

Notwithstanding the first paragraph above, the Company and its Restricted Subsidiaries may Incur Permitted Debt.

For purposes of determining any particular amount of Debt under this Section 4.9, (x) Debt Incurred under the Credit Agreement on the Issue Date shall at all times be treated as Incurred pursuant to clause (i) of the definition of “Permitted Debt,” and (y) Guarantees or obligations with respect to letters of credit supporting Debt otherwise included in the determination of such particular amount shall not be included. For purposes of determining compliance with this Section 4.9, in the event that an item of Debt meets the criteria of more than one of the types of Debt described above, including categories of Permitted Debt and under the first paragraph of this Section 4.9, the Company, in its sole discretion, shall classify, and from time to time may reclassify, all or any portion of such item of Debt.

-59-

The accrual of interest, the accretion or amortization of original issue discount and the payment of interest on Debt in the form of additional Debt or payment of dividends on Capital Interests in the forms of additional shares of Capital Interests with the same terms will not be deemed to be an Incurrence of Debt or issuance of Capital Interests for purposes of this Section 4.9.

The Company and any Guarantor will not Incur any Debt that pursuant to its terms is subordinate or junior in right of payment to any Debt unless such Debt is subordinated in right of payment to the Notes and the Note Guarantees to the same extent; provided that Debt will not be considered subordinate or junior in right of payment to any other Debt solely by virtue of being unsecured or secured to a greater or lesser extent or with greater or lower priority or by virtue of structural subordination.

SECTION 4.10 Limitation on Liens.

The Company will not, and will not permit any of its Restricted Subsidiaries, directly or indirectly, to enter into, create, incur, assume or suffer to exist any Liens of any kind (other than Permitted Liens) on or with respect to any of its property or assets now owned or hereafter acquired or any interest therein or any income or profits therefrom, which Liens secure Debt, without securing the Notes and all other amounts due under this Indenture equally and ratably with (or prior to) the Debt secured by such Lien until such time as such Debt is no longer secured by such Lien; provided that if the Debt so secured is subordinated by its terms to the Notes or a Note Guarantee, the Lien securing such Debt will also be so subordinated by its terms to the Notes and the Guarantees at least to the same extent.

SECTION 4.11 Limitation on Sale and Leaseback Transactions.

The Company will not, and will not permit any of its Restricted Subsidiaries to, enter into any Sale and Leaseback Transaction unless:

(i) the consideration received in such Sale and Leaseback Transaction is at least equal to the Fair Market Value of the property sold, as determined by an Officers’ Certificate, and

(ii) prior to and after giving effect to the Attributable Debt in respect of such Sale and Leaseback Transaction, the Company and such Restricted Subsidiary comply with Section 4.9.

SECTION 4.12 Offer to Purchase upon Change of Control.

Upon the occurrence of a Change of Control, unless the Company has exercised its rights to redeem all of the Notes in accordance with Section 3.7, the Issuer will make an Offer to Purchase (the “Change of Control Offer”) all of the outstanding Notes at a Purchase Price in cash equal to 101% of the principal amount tendered, together with accrued interest, if any, to but not including the Purchase Date (the “Change of Control Payment”). For purposes of the foregoing, an Offer to Purchase shall be deemed to have been made if (i) within 60 days following the date of the consummation of a transaction or series of transactions that constitutes a Change of Control,

-60-

the Issuer commences an Offer to Purchase for all outstanding Notes at the Purchase Price (provided that the running of such 60-day period shall be suspended, for up to a maximum of 30 days, during any period when the commencement of such Offer to Purchase is delayed or suspended by reason of any court’s or governmental authority’s review of or ruling on any materials being employed by the Issuer to effect such Offer to Purchase, so long as the Issuer has used and continues to use its commercial best efforts to make and conclude such Offer to Purchase promptly) and (ii) all Notes properly tendered pursuant to the Offer to Purchase are purchased on the terms of such Offer to Purchase.

The Change of Control provisions described above will be applicable whether or not any other provisions of this Indenture are applicable. Except as described above with respect to a Change of Control, this Indenture does not contain provisions that permit the Holders to require that the Issuer repurchase or redeem the Notes in the event of a takeover, recapitalization or similar transaction.

The Issuer shall not be required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth herein applicable to a Change of Control Offer made by the Issuer and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer.

To the extent that the provisions of any securities laws or regulations conflict with the Change of Control provisions of this Indenture, the Issuer will comply with the applicable securities laws and regulations and will not be deemed to have breached their obligations under the Change of Control provisions of this Indenture by virtue of such conflict.

In addition, an Offer to Purchase may be made in advance of a Change of Control, conditional upon such Change of Control, if a definitive agreement is in place for the Change of Control at the time of launching the Offer to Purchase.

SECTION 4.13 Corporate Existence.

Subject to Section 4.12 and Article V hereof, as the case may be, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence and the corporate, partnership, limited liability company or other existence of each of the Restricted Subsidiaries in accordance with the respective organizational documents (as the same may be amended from time to time) of the Company or any such Restricted Subsidiary and the rights (charter and statutory), licenses and franchises of the Company and its Restricted Subsidiaries; provided that the Company 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 of the Company shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and its Restricted Subsidiaries, taken as a whole.

-61-

SECTION 4.14 Additional Note Guarantees.

After the Issue Date, the Company shall cause each of its wholly-owned Domestic Restricted Subsidiaries that Incurs any Debt pursuant to clause (i) of the definition of “Permitted Debt” to guarantee the Notes.

SECTION 4.15 Limitation on Creation of Unrestricted Subsidiaries.

The Company may designate any Subsidiary of the Company to be an “Unrestricted Subsidiary” as provided below, in which event such Subsidiary and each other Person that is then or thereafter becomes a Subsidiary of such Subsidiary will be deemed to be an Unrestricted Subsidiary.

The Company may designate any Subsidiary to be an Unrestricted Subsidiary unless such Subsidiary owns any Capital Interests of, or owns or holds any Lien on any property of, any other Restricted Subsidiary of the Company, provided that either:

(x) the Subsidiary to be so designated has total assets of $1,000 or less; or

(y) the Company could make a Restricted Payment at the time of designation in an amount equal to the greater of the Fair Market Value or book value of such Subsidiary pursuant to Section 4.7 and such amount is thereafter treated as a Restricted Payment for the purpose of calculating the amount available for Restricted Payments thereunder.

An Unrestricted Subsidiary may be designated as a Restricted Subsidiary if (i) all the Debt of such Unrestricted Subsidiary could be Incurred pursuant to Section 4.9 and (ii) all the Liens on the property and assets of such Unrestricted Subsidiary could be incurred pursuant to Section 4.10.

SECTION 4.16 Maintenance of Properties; Insurance; Books and Records.

(a) Subject to, and in compliance with, the provisions of Article X, the Issuer shall cause all material properties used or useful in the conduct of its business or the business of any of the Guarantors to be maintained and kept in good operating condition, repair and working order (ordinary wear and tear and casualty loss excepted) and supplied with all necessary equipment and shall cause to be made all necessary repairs, renewals, replacements, betterments and improvements thereto; provided that the Issuer shall not be obligated to make such repairs, renewals, replacements, betterments and improvements that, if failed to be made, would not result in a material adverse effect on the ability of the Issuer and the Guarantors to satisfy their obligations under the Notes, the Guarantees and this Indenture.

(b) The Issuer shall maintain, and shall cause the Guarantors to maintain, insurance with responsible carriers against such risks and in such amounts, and with such deductibles, retentions, self-insured amounts and co-insurance provisions, as are customarily carried by similar businesses of similar size in the locations which such business is conducted, including property and casualty loss, workers’ compensation and interruption of business insurance.

-62-

(c) The Issuer shall, and shall cause each Guarantor to, keep proper books of record and account, in which full and correct entries shall be made of all financial transactions of the Issuer and each of the Guarantors, in accordance with GAAP.

SECTION 4.17 Covenant Suspension.

(a) If on any date following the Issue Date (i) the Notes have Investment Grade Ratings from both Rating Agencies and (ii) no Default has occurred and is continuing under this Indenture (the occurrence of the events described in the foregoing clauses (i) and (ii) being collectively referred to as a “Covenant Suspension Event”) and upon receipt of an Officer’s Certificate certifying that the events in (i) and (ii) have occurred, the Company and the Restricted Subsidiaries will not be subject to the covenants (the “Suspended Covenants”) described under:

(i) Section 4.7;

(ii) Section 4.8; and

(iii) Section 4.9.

(b) In the event that the Company and the Restricted Subsidiaries are not subject to the Suspended Covenants under this Indenture for any period of time as a result of the foregoing, and on any subsequent date (the “Reversion Date”) (a) one or both of the Rating Agencies withdraw their Investment Grade Rating or downgrade the rating assigned to the Notes below an Investment Grade Rating or (b) the Company or any of its Affiliates enters into an agreement to effect a transaction that would result in a Change of Control and one or more of the Rating Agencies indicate that if consummated, such transaction (alone or together with any related recapitalization or refinancing transactions) would cause such Rating Agency to withdraw its Investment Grade Rating or downgrade the ratings assigned to the Notes below an Investment Grade Rating and upon receipt of an Officer’s Certificate certifying that the events in (a) or (b) in this subsection have occurred, then the Company and the Restricted Subsidiaries will thereafter again be subject to the Suspended Covenants under this Indenture with respect to future events.

(c) The period of time between the occurrence of a Covenant Suspension Event and the Reversion Date is referred to in this description as the “Suspension Period.” In the event of any such reinstatement, no action taken or omitted to be taken by the Company or any of its Restricted Subsidiaries prior to such reinstatement will give rise to a Default or Event of Default under this Indenture with respect to Notes; provided that (1) with respect to Restricted Payments made after any such reinstatement, the amount of Restricted Payments made will be calculated as though the covenant described under Section 4.7 had been in effect prior to, but not during, the Suspension Period, provided that any Subsidiaries designated as Unrestricted Subsidiaries during the Suspension Period shall automatically become Restricted Subsidiaries on the Reversion Date (subject to the Company’s right to subsequently designate them as Unrestricted Subsidiaries in compliance with the covenants set out below), and (2) all Debt Incurred, or Disqualified Stock or Preferred Stock issued, during the Suspension Period will be classified as having been Incurred or issued pursuant to clause (iv) of the definition of “Permitted Debt” except for Debt Incurred under any Credit Facilities, which shall be classified as having been Incurred or issued pursuant to clause (i) of the definition of “Permitted Debt.”

SUCCESSORS

SECTION 5.1 Consolidation, Merger, Conveyance, Transfer or Lease.

The Company will not in any transaction or series of transactions, consolidate with or merge into any other Person (other than a merger of a Restricted Subsidiary into the Company in which the Company is the continuing Person or the merger of a Restricted Subsidiary into or with another Restricted Subsidiary or another Person that as a result of such transaction becomes or merges into a Restricted Subsidiary), or sell, assign, convey, transfer, lease or otherwise dispose of all or substantially all of the assets of the Company and its Restricted Subsidiaries (determined on a consolidated basis), taken as a whole, to any other Person, unless:

(i) either: (a) the Company shall be the continuing Person or (b) the Person (if other than the Company) formed by such consolidation or into which the Company is merged, or the Person that acquires, by sale, assignment, conveyance, transfer, lease or other disposition, all or substantially all of the property and assets of the Company (such Person, the “Surviving Entity”), (1) shall be a corporation, partnership, limited liability company or similar entity organized and validly existing under the laws of the United States, any political subdivision thereof or any state thereof or the District of Columbia and (2) shall expressly assume, by a supplemental indenture, the due and punctual payment of all amounts due in respect of the principal of (and premium, if any) and interest on all the Notes and the performance of the covenants and obligations of the Company under this Indenture; provided that at any time the Company or its successor is not a corporation, there shall be a co-issuer of the Notes that is a corporation;

(ii) immediately after giving effect to such transaction or series of transactions on a pro forma basis (including, without limitation, any Debt Incurred or anticipated to be Incurred in connection with or in respect of such transaction or series of transactions), no Default or Event of Default shall have occurred and be continuing or would result therefrom; and

(iii) the Company delivers, or causes to be delivered, to the Trustee, in form satisfactory to the Trustee, an Officers’ Certificate and an Opinion of Counsel, each stating that such consolidation, merger, sale, conveyance, assignment, transfer, lease or other disposition complies with the requirements of this Indenture and that such supplemental indenture constitutes the legal, valid and binding obligation of the Surviving Entity, subject to customary exceptions.

-64-

Notwithstanding the foregoing, failure to satisfy the requirements of the preceding clause (ii) will not prohibit:

(a) a merger between the Company and a Restricted Subsidiary that is a wholly owned Subsidiary of the Company; or

(b) a merger between the Company and an Affiliate incorporated solely for the purpose of converting the Company into a corporation organized under the laws of the United States or any political subdivision or state thereof;

so long as, in each case, the amount of Debt of the Company and its Restricted Subsidiaries is not increased thereby.

For all purposes of this Indenture and the Notes, Subsidiaries of any Surviving Entity will, upon such transaction or series of transactions, become Restricted Subsidiaries or Unrestricted Subsidiaries as provided pursuant to this Indenture and all Debt, and all Liens on property or assets, of the Surviving Entity and its Subsidiaries that was not Debt, or were not Liens on property or assets, of the Company and its Subsidiaries immediately prior to such transaction or series of transactions shall be deemed to have been Incurred upon such transaction or series of transactions.

SECTION 5.2 Successor Person Substituted.

Upon any consolidation or merger, or any sale, assignment, conveyance, transfer, lease or other disposition of all or substantially all of the assets of the Company in accordance with Section 5.1 hereof, the successor corporation formed by such consolidation or into or with which the Company (and, if necessary, any co-issuer) is merged or to which such sale, assignment, conveyance, transfer, lease or other disposition is made shall succeed to, and be substituted for (so that from and after the date of such consolidation, merger, sale, lease, conveyance or other disposition, the provisions of this Indenture referring to the “Company” shall refer instead to the successor corporation and not to the Company), and shall exercise every right and power of, the Company under this Indenture with the same effect as if such successor Person had been named as the Company herein; provided, however, that in the case of a lease, the predecessor shall be relieved of all such obligations.

ARTICLE VI

DEFAULTS AND REMEDIES

SECTION 6.1 Events of Default.

Each of the following constitutes an “Event of Default”:

(1) default in the payment in respect of the principal of (or premium, if any, on) any Note when due and payable (whether at Stated Maturity or upon repurchase, acceleration, optional redemption or otherwise);

-65-

(2) default in the payment of any interest upon any Note when it becomes due and payable, and continuance of such default for a period of 30 days;

(3) except as permitted by this Indenture, any Note Guarantee of any Significant Subsidiary (or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary) shall for any reason cease to be, or it shall be asserted by any Guarantor or the Company not to be, in full force and effect and enforceable in accordance with its terms;

(4) default in the performance, or breach, of any covenant or agreement of the Company or any Guarantor in this Indenture (other than a covenant or agreement a default in whose performance or whose breach is specifically dealt with in clause (1), (2) or (3) above), and continuance of such default or breach for a period of 60 days after written notice thereof (or 120 days in the case of the covenant described under Section 4.3) has been given to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in aggregate principal amount of the outstanding Notes;

(5) a default or defaults under any bonds, debentures, notes or other evidences of Debt (other than the Notes) by the Company or any Restricted Subsidiary having, individually or in the aggregate, a principal or similar amount outstanding of at least $50.0 million, whether such Debt now exists or shall hereafter be created, which default or defaults shall have resulted in the acceleration of the maturity of such Debt prior to its express maturity or shall constitute a failure to pay at least $50.0 million of such Debt when due and payable after the expiration of any applicable grace period with respect thereto;

(6) the entry against the Company or any Restricted Subsidiary that is a Significant Subsidiary of a final judgment or final judgments for the payment of money in an aggregate amount in excess of $50.0 million, by a court or courts of competent jurisdiction, which judgments remain undischarged, unwaived, unstayed, unbonded or unsatisfied for a period of 60 consecutive days; or

(7) (i) the Company, any Restricted Subsidiary that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary, pursuant to or within the meaning of any Bankruptcy Law:

(a) commences a voluntary case,

(b) consents to the entry of an order for relief against it in an involuntary case,

-66-

(d) makes a general assignment for the benefit of its creditors, or

(e) generally is not paying its debts as they become due; or

(ii) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that:

(a) is for relief against the Company or any Restricted Subsidiary that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary, in an involuntary case;

(b) appoints a custodian of the Company or any Restricted Subsidiary that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary or for all or substantially all of the property of the Company or any of its Restricted Subsidiaries; or

(c) orders the liquidation of the Company or any Restricted Subsidiary that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary

and the order or decree remains unstayed and in effect for 60 consecutive days.

SECTION 6.2 Acceleration.

If an Event of Default (other than an Event of Default specified in clause (7) of Section 6.1 with respect to the Company) occurs and is continuing, then and in every such case the Trustee or the Holders of not less than 25% in aggregate principal amount of the outstanding Notes may declare the principal of the Notes and any accrued interest on the Notes to be due and payable immediately by a notice in writing to the Company (and to the Trustee if given by Holders); provided, however, that after such acceleration, but before a judgment or decree based on acceleration, the Holders of a majority in aggregate principal amount of the outstanding Notes may, under certain circumstances, rescind and annul such acceleration if all Events of Default, other than the nonpayment of accelerated principal of or interest on the Notes, have been cured or waived as provided in this Indenture.

In the event of a declaration of acceleration of the Notes solely because an Event of Default described in clause (5) of Section 6.1 has occurred and is continuing, the declaration of acceleration of the Notes shall be automatically rescinded and annulled if the Event of Default or payment default triggering such Event of Default pursuant to clause (5) of Section 6.1 shall be remedied or cured by the Company or a Restricted Subsidiary of the Company or waived by the holders of the relevant Debt within 20 Business Days after the declaration of acceleration with respect thereto and if the rescission and annulment of the acceleration of the Notes would not conflict with any judgment or decree of a court of competent jurisdiction obtained by the Trustee for the payment of amounts due on the Notes.

If an Event of Default specified in clause (7) of Section 6.1 occurs with respect to the Company, the principal of and any accrued interest on the Notes then outstanding shall ipso facto

-67-

become immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. The Trustee may withhold from Holders notice of any Default (except Default in payment of principal of, premium, if any, and interest) if the Trustee determines that withholding notice is in the interest of the Holders to do so.

No Holder of any Note will have any right to institute any proceeding with respect to this Indenture or for any remedy thereunder, unless such Holder shall have previously given to the Trustee written notice of a continuing Event of Default and unless also the Holders of at least 25% in aggregate principal amount of the outstanding Notes shall have made written request, and offered indemnity reasonably satisfactory to the Trustee, to the Trustee to institute such proceeding as Trustee, and the Trustee shall not have received from the Holders of a majority in aggregate principal amount of the outstanding Notes a direction inconsistent with such request and shall have failed to institute such proceeding within 60 days. Such limitations do not apply, however, to a suit instituted by a Holder of a Note for enforcement of payment of the principal of (and premium, if any) or interest on such Note on or after the respective due dates expressed in such Note.

SECTION 6.3 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, if any, 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 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.

Pursuant to Section 4.4, the Company is required to deliver to the Trustee annually a statement regarding compliance with this Indenture, and the Company is required upon becoming aware of any Default or Event of Default, to deliver to the Trustee a statement specifying such Default or Event of Default.

SECTION 6.4 Waiver of Past Defaults.

The Holders of a majority in aggregate principal amount of the Notes then outstanding by notice to the Trustee may on behalf of the Holders of all of the Notes waive any existing Default or Event of Default and its consequences under this Indenture except a continuing Default or Event of Default in the payment of interest on, or the principal of, the Notes (other than as a result of an acceleration), which shall require the consent of all of the Holders of the Notes then outstanding.

SECTION 6.5 Control by Majority.

The Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the time, method and place of conducting any proceeding for exercising any remedy

-68-

available to the Trustee or exercising any trust power conferred on the Trustee. However, (i) the Trustee may refuse to follow any direction that conflicts with law or this Indenture, that the Trustee determines may be unduly prejudicial to the rights of other Holders or that may involve the Trustee in personal liability, and (ii) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction received from the Holders of a majority in aggregate principal amount of the then outstanding Notes.

SECTION 6.6 Limitation on Suits.

A Holder may pursue a remedy with respect to this Indenture or the Notes only if:

(a) the Holder gives to the Trustee written notice of a continuing Event of Default or the Trustee receives such notice from the Company;

(b) the Holders of at least 25% in aggregate principal amount of the then outstanding Notes make a written request to the Trustee to pursue the remedy;

(c) such Holder or Holders offer and, if requested, provide to the Trustee indemnity or security reasonably satisfactory to the Trustee against any loss, liability or expense;

(d) the Trustee does not comply with the request within 60 days after receipt of the request and the offer and, if requested, the provision of such indemnity or security; and

(e) during such 60-day period the Holders of a majority in aggregate principal amount of the then outstanding Notes do not give the Trustee a direction that is inconsistent with the request.

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

SECTION 6.7 Rights of Holders of Notes to Receive Payment.

Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal, premium, if any, and interest 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.

SECTION 6.8 Collection Suit by Trustee.

If an Event of Default specified in Section 6.1(1) or (2) hereof 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 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.

-69-

SECTION 6.9 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 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 securities or property payable or deliverable upon the conversion or exchange of the Notes or 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 7.7 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 7.7 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.

Any money collected by the Trustee pursuant to this Article VI and any money or other property distributable in respect of the Company’s obligations under this Indenture after an Event of Default shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal (or premium, if any) or interest, if any, upon presentation of the Notes and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid:

First: to the Trustee (including any predecessor Trustee), its agents and attorneys for amounts due under Section 7.7 hereof, including payment of all reasonable compensation, expense 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, 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, if any, and interest respectively; and

-70-

Third: to the Issuer or to such party as a court of competent jurisdiction shall direct.

The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 6.10.

SECTION 6.11 Undertaking for Costs.

In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.7 hereof, or a suit by Holders of more than 10% in principal amount of the then outstanding Notes.

SECTION 6.12 Restoration of Rights and Remedies.

If the Trustee or any Holder has instituted a proceeding to enforce any right or remedy under the Indenture and the proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to the Holder, then, subject to any determination in the proceeding, the Company, any Guarantors, the Trustee and the Holders will be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Company, any Guarantors, the Trustee and the Holders will continue as though no such proceeding had been instituted.

SECTION 7.3 Individual Rights of Trustee.

The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Issuer or any Affiliate of the Issuer with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest as defined in Section 310(b) of the TIA, it must eliminate such conflict within 90 days, apply to the Commission for permission to continue as Trustee or resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to Sections 7.10 and 7.11 hereof.

SECTION 7.4 Trustee’s Disclaimer.

The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Notes or the Offering Memorandum, and it shall not be accountable for the Issuer’s use of the proceeds from the Notes or any money paid to the Issuer’s or upon the Issuer’s direction under any provision of this Indenture, it shall not be responsible for the use or application of any money received by any Paying Agent other than the Trustee, and it shall not be responsible for any statement or recital herein or any statement in the Notes, any statement or recital in any document in connection with the sale of the Notes or pursuant to this Indenture other than its certificate of authentication on the Notes.

SECTION 7.5 Notice of Defaults.

If a Default occurs and is continuing and a Responsible Officer of the Trustee has received written notice of such Default, the Trustee shall send electronically or mail to Holders a notice of the Default within 90 days after the Trustee has received written notice of such Default. Except in the case of a Default in payment of principal of, premium, if any, or interest on any Note, the Trustee may withhold the notice if and so long as the Trustee in good faith determines that withholding the notice is in the interests of the Holders.

SECTION 7.6 Reports by Trustee to Holders of the Notes.

Within 60 days after each June 1 beginning with the June 1, 2011, and for so long as Notes remain outstanding, the Trustee shall send to the Holders a brief report dated as of such reporting date that complies with TIA § 313(a) (but if no event described in TIA § 313(a) has occurred within the twelve months preceding the reporting date, no report need be transmitted).

-74-

The Trustee also shall comply with TIA § 313(b). The Trustee shall also transmit by mail all reports as required by TIA § 313(c).

A copy of each report at the time of its delivery to the Holders shall be mailed or delivered to the Company and filed with the Commission and each stock exchange on which the Company has informed the Trustee in writing the Notes are listed in accordance with TIA § 313(d). The Company shall promptly notify the Trustee when the Notes are listed on any stock exchange and of any delisting thereof.

SECTION 7.7 Compensation and Indemnity.

The Issuer shall pay to the Trustee from time to time compensation for its acceptance of this Indenture and services hereunder as the parties will agree from time to time. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Issuer shall reimburse the Trustee as promptly as practicable upon request for all reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such expenses shall include, but not limited to, the reasonable compensation, disbursements and expenses of the Trustee’s agents and counsel.

The Issuer and the Guarantors, jointly and severally, shall indemnify the Trustee (which for purposes of this Section 7.7 shall include its officers, directors, employees and agents) against any and all claims, damage, losses, liabilities or expenses (including attorneys’ fees) incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture, including the costs and expenses of enforcing this Indenture against the Issuer and the Note Guarantees against the Guarantors (including this Section 7.7) and defending itself against any claim (whether asserted by the Issuer or any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder except to the extent any such loss, claim, damage, liability or expense may be attributable to its negligence, willful misconduct or bad faith. The Trustee shall notify the Issuer promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Issuer shall not relieve the Issuer of its obligations hereunder. The Trustee may have separate counsel and the Issuer shall pay the reasonable fees and expenses of one such counsel. The Issuer need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld. Under no circumstances shall the Trustee be liable for any special, indirect, consequential or punitive damages of any kind.

The obligations of the Issuer and the Guarantors under this Section 7.7 shall survive the satisfaction and discharge or termination for any reason of this Indenture or the resignation or removal of the Trustee.

To secure the Issuer’s and the Guarantors’ obligations in this Section 7.7, the Trustee shall have a Lien prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal or interest, if any, on particular Notes. Such Lien shall survive the satisfaction and discharge or termination for any reason of this Indenture and the resignation or removal of the Trustee.

-75-

In addition, and without prejudice to the rights provided to the Trustee under any of the provisions of this Indenture, when the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.1(7) hereof occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law.

“Trustee” for the purposes of this Section 7.7 shall include any predecessor Trustee and the Trustee in each of its capacities hereunder and each agent, custodian and other person employed to act hereunder; provided, however, that the negligence, willful misconduct or bad faith of any Trustee hereunder shall not affect the rights of any other Trustee hereunder.

The Trustee shall comply with the provisions of TIA § 313(b)(2) to the extent applicable.

SECTION 7.8 Replacement of Trustee.

A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee’s acceptance of appointment as provided in this Section 7.8.

The Trustee may resign at any time and be discharged from the trust hereby created by so notifying the Issuer in writing. The Holders of a majority in principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Issuer in writing. The Issuer may remove the Trustee if:

(a) the Trustee fails to comply with Section 7.10 hereof;

(b) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy Law;

(d) the Trustee becomes incapable of acting.

If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Issuer shall notify each Holder of such event and shall promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of all outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Issuer.

Promptly after that, the retiring Trustee shall transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided in Section 7.7 hereof, the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The Issuer shall pay all amounts due to the retiring trustee at the time of such succession. A successor Trustee shall deliver notice of its succession to each Holder.

-76-

If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Issuer or the Holders of at least 10% in aggregate principal amount of all outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee.

If the Trustee fails to comply with Section 7.10 hereof, any Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

Notwithstanding replacement of the Trustee pursuant to this Section 7.8, the Issuer’s obligations under Section 7.7 hereof shall continue for the benefit of the retiring Trustee.

SECTION 7.9 Successor Trustee by Merger, Etc.

If the Trustee or any Agent consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another Person, the successor Person without any further act shall be the successor Trustee or any Agent, as applicable.

SECTION 7.10 Eligibility; Disqualification.

There shall at all times be a Trustee hereunder that is a corporation organized and doing business under the laws of the United States of America or of any state thereof that is authorized under such laws to exercise corporate trustee power and that is subject to supervision or examination by federal or state authorities. The Trustee together with its affiliates shall at all times have a combined capital and surplus of at least $50.0 million as set forth in its most recent annual report of condition.

This Indenture shall always have a Trustee who satisfies the requirements of TIA §§ 310(a)(l), (2) and (5). If this Indenture becomes qualified under the TIA, the Trustee shall be subject to TIA § 310(b) including the provision in § 310(b)(1); provided that there shall be excluded from the operation of TIA § 310(b)(1) any indenture or indentures under which other securities, or certificates of interest or participation in other securities, of the Issuer or the Guarantors are outstanding if the requirements for exclusion set forth in TIA § 310(b)(1) are met.

SECTION 7.11 Preferential Collection of Claims Against the Issuer.

The Trustee is subject to TIA § 311(a), excluding any creditor relationship listed in TIA § 311(b). A Trustee who has resigned or been removed shall be subject to TIA § 311(a) to the extent indicated therein.

SECTION 7.12 Trustee’s Application for Instructions from the Issuer.

Any application by the Trustee for written instructions from the Issuer may, at the option of the Trustee, set forth in writing any action proposed to be taken or omitted by the Trustee under this Indenture and the date on and/or after which such action shall be taken or such omission shall be effective. The Trustee shall not be liable for any action taken by, or omission of, the Trustee in accordance with a proposal included in such application on or after the date specified

-77-

in such application (which date shall not be less than twenty Business Days after the date any officer of the Issuer actually receives such application, unless any such officer shall have consented in writing to any earlier date) unless prior to taking any such action (or the effective date in the case of an omission), the Trustee shall have received written instructions in response to such application specifying the action to be taken or omitted.

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

SECTION 8.1 Option to Effect Defeasance or Covenant Defeasance.

SECTION 8.2 Defeasance and Discharge.

Upon the Issuer’s exercise under Section 8.1 hereof of the option applicable to this Section 8.2, the Issuer shall, subject to the satisfaction of the conditions set forth in Section 8.4 hereof, be deemed to have been discharged from its obligations with respect to all outstanding Notes on the date the conditions set forth below are satisfied (hereinafter, “legal defeasance”). For this purpose, legal defeasance means that the Issuer shall be deemed to have paid and discharged the entire Debt represented by the outstanding Notes, which shall thereafter be deemed to be “outstanding” only for the purposes of Section 8.5 hereof and the other Sections of this Indenture referred to in (a) and (b) below, and to have satisfied all of its other obligations under such Notes 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 shall survive until otherwise terminated or discharged hereunder: (a) the rights of Holders of outstanding Notes to receive payments in respect of the principal of, premium, if any, and interest, if any, on such Notes when such payments are due from the trust referred to in Section 8.4(l); (b) the Issuer’s obligations with respect to such Notes under Sections 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.10 and 4.2 hereof; (c) the rights, powers, trusts, benefits and immunities of the Trustee, including without limitation thereunder, under Section 7.7, 8.5 and 8.7 hereof and the Issuer’s obligations in connection therewith; and (d) the provisions of this Article VIII. Subject to compliance with this Article VIII, the Issuer may exercise its option under this Section 8.2 notwithstanding the prior exercise of its option under Section 8.3 hereof.

The Issuer and the Guarantors may terminate the obligations under this Indenture when:

(1) either: (A) all Notes theretofore authenticated and delivered have been delivered to the Trustee for cancellation, or (B) all such Notes not theretofore delivered to the Trustee for cancellation (i) have become due and payable or (ii) will become due and payable within one year or are to be called for redemption within one year (a “Discharge”)

-78-

under irrevocable arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company, and the Company has irrevocably deposited or caused to be deposited with the Trustee funds in an amount sufficient to pay and discharge the entire indebtedness on the Notes, not theretofore delivered to the Trustee for cancellation, for principal of, premium, if any, and interest to the Stated Maturity or date of redemption;

(2) the Issuer has paid or caused to be paid all other sums then due and payable under this Indenture by the Issuer;

(3) the deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which the Issuer or any Guarantor is a party or by which the Issuer or any Guarantor is bound;

(4) the Issuer has delivered irrevocable instructions to the Trustee under this Indenture to apply the deposited money toward the payment of the Notes at maturity or on the redemption date, as the case may be; and

(5) the Issuer has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel reasonably acceptable to the Trustee, each stating that all conditions precedent under this Indenture relating to the Discharge have been complied with.

The Issuer may elect, at its option, to have its obligations discharged with respect to the outstanding Notes. Such legal defeasance means that the Issuer will be deemed to have paid and discharged the entire indebtedness represented by the outstanding Notes, except for:

(1) the rights of Holders of such Notes to receive payments in respect of the principal of and any premium and interest on such Notes when payments are due,

(2) the Issuer’s obligations with respect to such Notes concerning issuing temporary Notes, registration of Notes, mutilated, destroyed, lost or stolen Notes and the maintenance of an office or agency for payment and money for security payments held in trust,

(3) the rights, powers, trusts, duties and immunities of the Trustee, and

(4) the defeasance provisions of this Indenture.

SECTION 8.3 Covenant Defeasance.

Upon the Issuer’s exercise under Section 8.1 hereof of the option applicable to this Section 8.3, the Issuer shall, subject to the satisfaction of the conditions set forth in Section 8.4 hereof, be released from its obligations under the covenants contained in Sections 4.3, 4.4, 4.7, 4.8, 4.9, 4.10, 4.11, 4.12, 4.14, 4.17 and 5.1 hereof with respect to the outstanding Notes on and after the date the conditions set forth below are satisfied (hereinafter, “covenant defeasance”), and the Notes shall thereafter be deemed not “outstanding” for the purposes of any direction,

-79-

waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes shall not be deemed outstanding for accounting purposes). For this purpose, covenant defeasance means that, with respect to the outstanding Notes, the Issuer or any of its Subsidiaries may omit to comply with and shall 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 shall not constitute a Default or an Event of Default under Section 6.1 hereof, but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby. In addition, upon the Issuer’s exercise under Section 8.1 hereof of the option applicable to this Section 8.3, subject to the satisfaction of the conditions set forth in Section 8.4 hereof, Section 6.1(4) hereof shall not constitute Events of Default.

SECTION 8.4 Conditions to Legal Defeasance or Covenant Defeasance.

The following shall be the conditions to the application of either Section 8.2 or 8.3 hereof to the outstanding Notes:

In order to exercise either legal defeasance or covenant defeasance:

(1) the Issuer must irrevocably have deposited or caused to be deposited with the Trustee as trust funds in trust for the purpose of making the following payments, specifically pledged as security for, and dedicated solely to the benefits of the Holders of such Notes: (A) money in an amount, or (B) U.S. government obligations which through the scheduled payment of principal and interest in respect thereof in accordance with their terms will provide, not later than the due date of any payment, money in an amount or (C) a combination thereof, in each case sufficient without reinvestment, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay and discharge, and which shall be applied by the Trustee to pay and discharge, the entire indebtedness in respect of the principal of and premium, if any, and interest on such Notes on the Stated Maturity thereof or (if the Issuer has made irrevocable arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name and at the expense of the Issuer) the redemption date thereof, as the case may be, in accordance with the terms of this Indenture and such Notes;

(2) in the case of legal defeasance, the Issuer shall have delivered to the Trustee an Opinion of Counsel stating that (A) the Issuer has received from, or there has been published by, the Internal Revenue Service a ruling or (B) since the date of this Indenture, there has been a change in the applicable United States federal income tax law, in either case (A) or (B) to the effect that, and based thereon such opinion shall confirm that, the Holders of such Notes will not recognize gain or loss for United States federal income tax purposes as a result of the deposit, legal defeasance and discharge to be effected with respect to such Notes and will be subject to United States federal income tax on the same amount, in the same manner and at the same times as would be the case if such deposit, legal defeasance and discharge were not to occur;

-80-

(3) in the case of covenant defeasance, the Issuer shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of such outstanding Notes will not recognize gain or loss for United States federal income tax purposes as a result of the deposit and covenant defeasance to be effected with respect to such Notes and will be subject to federal income tax on the same amount, in the same manner and at the same times as would be the case if such deposit and covenant defeasance were not to occur;

(4) no Default or Event of Default with respect to the outstanding Notes shall have occurred and be continuing at the time of such deposit after giving effect thereto (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit and the grant of any Lien to secure such borrowing);

(5) such legal defeasance or covenant defeasance shall not cause the Trustee to have a conflicting interest within the meaning of the TIA (assuming all Notes are in default within the meaning of the TIA);

(6) such legal defeasance or covenant defeasance shall not result in a breach or violation of, or constitute a default under, any material agreement or material instrument (other than this Indenture) to which the Company is a party or by which the Company is bound; and

(7) the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent with respect to such legal defeasance or covenant defeasance have been complied with.

In the event of a legal defeasance or a Discharge, a Holder whose taxable year straddles the deposit of funds and the distribution in redemption to such Holder would be subject to tax on any gain (whether characterized as capital gain or market discount) in the year of deposit rather than in the year of receipt. In connection with a Discharge, in the event the Issuer becomes insolvent within the applicable preference period after the date of deposit, monies held for the payment of the Notes may be part of the bankruptcy estate of the Issuer, disbursement of such monies may be subject to the automatic stay of the Bankruptcy Code and monies disbursed to Holders may be subject to disgorgement in favor of the Issuer’s estate. Similar results may apply upon the insolvency of the Issuer during the applicable preference period following the deposit of monies in connection with defeasance.

Notwithstanding the foregoing, the Opinion of Counsel required by clause (2) above with respect to a legal defeasance need not to be delivered if all Notes not therefore delivered to the Trustee for cancellation (x) have become due and payable, or (y) will become due and payable at Stated Maturity within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company.

-81-

SECTION 8.5 Deposited Money and Government Securities to Be Held in Trust; Other Miscellaneous Provisions.

Subject to Section 8.6 hereof, all money and non-callable U.S. government obligations (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.5, the “Trustee”) pursuant to Section 8.4 hereof in respect of the outstanding Notes shall be held in trust, shall not be invested, and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company or any Subsidiary acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium, if any, and interest, but such money need not be segregated from other funds except to the extent required by law.

The Issuer shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable U.S. government obligations deposited pursuant to Section 8.4 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes.

Anything in this Article VIII to the contrary notwithstanding, the Trustee shall deliver or pay to the Issuer from time to time upon the written request of the Issuer and be relieved of all liability with respect to any money or non-callable U.S. government obligations held by it as provided in Section 8.4 hereof which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.4(1) hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent defeasance or covenant defeasance.

SECTION 8.6 Repayment to Issuer.

Any money deposited with the Trustee or any Paying Agent, or then held by the Issuer, in trust for the payment of the principal of, premium, if any, or interest, if any, on any Note and remaining unclaimed for one year after such principal and premium, if any, or interest has become due and payable shall be paid to the Issuer on its written request or (if then held by the Issuer) shall be discharged from such trust; and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the Issuer for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Issuer as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Issuer cause to be published once, in The New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such notification or publication, any unclaimed balance of such money then remaining shall be repaid to the Issuer.

-82-

SECTION 8.7 Reinstatement.

If the Trustee or Paying Agent is unable to apply any United States dollars or non-callable U.S. government obligations in accordance with Section 8.2 or 8.3 hereof, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the obligations of the Issuer under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.2 or 8.3 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.2 or 8.3 hereof, as the case may be; provided, however, that, if the Issuer makes any payment of principal of, premium, if any, or interest on any Note following the reinstatement of its obligations, the Issuer shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent.

The Issuer may, but shall not be obligated to, fix a record date for determining which Holders consent to such amendment, supplement or waiver. If the Issuer fixes a record date, the record date shall be fixed at (i) the later of 30 days prior to the first solicitation of such consent or the date of the most recent list of Holders furnished for the Trustee prior to such solicitation pursuant to Section 2.5 hereof or (ii) such other date as the Issuer shall designate.

SECTION 9.5 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 authenticate new Notes that reflect the amendment, supplement or waiver.

-85-

SECTION 9.6 Trustee to Sign Amendments, Etc.

The Trustee shall sign any amended or supplemental indenture authorized pursuant to this Article IX 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 amendment or supplemental indenture until their respective Boards of Directors approve it.

(c) Each Guarantor hereby waives the benefits of diligence, presentment, demand for payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company or any other Person, protest, notice and all demands whatsoever and covenants that the Note Guarantee of such Guarantor shall not

-86-

be discharged as to any Note except by complete performance of the obligations contained in such Note and such Note Guarantee or as provided for in this Indenture. Each of the Guarantors hereby agrees that, in the event of a default in payment of principal or premium, if any or interest on such Note, whether at its Stated Maturity, by acceleration, call for redemption, purchase or otherwise, legal proceedings may be instituted by the Trustee on behalf of, or by, the Holder of such Note, subject to the terms and conditions set forth in this Indenture, directly against each of the Guarantors to enforce such Guarantor’s Note Guarantee without first proceeding against the Company or any other Guarantor. Each Guarantor agrees that if, after the occurrence and during the continuance of an Event of Default, the Trustee or any of the Holders are prevented by applicable law from exercising their respective rights to accelerate the maturity of the Notes, to collect interest on the Notes, or to enforce or exercise any other right or remedy with respect to the Notes, such Guarantor shall pay to the Trustee for the account of the Holders, upon demand therefor, the amount that would otherwise have been due and payable had such rights and remedies been permitted to be exercised by the Trustee or any of the Holders.

(d) If any Holder or the Trustee is required by any court or otherwise to return to the Issuer or any Guarantor, or any custodian, trustee, liquidator or other similar official acting in relation to the Issuer or any Guarantor, any amount paid by any of them to the Trustee or such Holder, the Note Guarantee of each of the Guarantors, to the extent theretofore discharged, shall be reinstated in full force and effect. This paragraph (d) shall remain effective notwithstanding any contrary action which may be taken by the Trustee or any Holder in reliance upon such amount required to be returned. This paragraph (d) shall survive the termination of this Indenture.

(e) Each Guarantor further agrees that, as between each Guarantor, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article VI hereof for the purposes of the Note Guarantee of such Guarantor, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any acceleration of such obligations as provided in Article VI hereof, such obligations (whether or not due and payable) shall forthwith become due and payable by each Guarantor for the purpose of the Note Guarantee of such Guarantor.

SECTION 10.2 Execution and Delivery of Note Guarantee.

To evidence its Note Guarantee set forth in Section 10.1, each Guarantor on the Issue Date agrees that a notation of such Note Guarantee substantially in the form attached hereto as Exhibit B shall be endorsed on each Note authenticated and delivered by the Trustee. Such notation of Note Guarantee shall be signed on behalf of such Guarantor by an officer of such Guarantor (or, if an officer is not available, by a board member or director) on behalf of such Guarantor by manual or facsimile signature. In case the officer, board member or director of such Guarantor who shall have signed such notation of Note Guarantee shall cease to be such officer, board member or director before the Note on which such Note Guarantee is endorsed shall have been authenticated and delivered by the Trustee, such Note nevertheless may be authenticated and delivered as though the Person who signed such notation of Note Guarantee had not ceased to be such officer, board member or director.

-87-

Each Guarantor agrees that its Note Guarantee set forth in Section 10.1 shall remain in full force and effect and apply to all the Notes notwithstanding any failure to endorse on each Note a notation of such Note Guarantee. The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of any Note Guarantee set forth in this Indenture on behalf of the Guarantors.

The failure to endorse a Note Guarantee shall not affect or impair the validity thereof.

SECTION 10.3 Severability.

In case any provision of any Note Guarantee shall be invalid, illegal or unenforceable, the validity, legality, and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

SECTION 10.4 Limitation of Guarantors’ Liability.

Each Guarantor and by its acceptance of Notes, each Holder, confirms that it is the intention of all such parties that the Note Guarantee of such Guarantor does not constitute a fraudulent transfer or conveyance for purposes of the Federal Bankruptcy Code, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law relating to fraudulent transfer or conveyance. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of such Guarantor under its Note Guarantee shall be limited to the maximum amount that will not, after giving effect to all other contingent and fixed liabilities of such Guarantor 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 its Note Guarantee, result in the obligations of such Guarantor under its Note Guarantee constituting a fraudulent transfer or conveyance.

SECTION 10.5 Guarantors May Consolidate, Etc., on Certain Terms.

Except as otherwise provided in Section 10.6, a Guarantor may not sell or otherwise dispose of all or substantially all of its assets, or consolidate with or merge with or into (whether or not such Guarantor is the surviving Person) another Person unless:

(1) immediately after giving effect to such transactions, no Default or Event of Default exists;

(2) 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 under this Indenture pursuant to a supplemental indenture satisfactory to the Trustee; and

(3) the Company delivers, or causes to be delivered, to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that such sale, other disposition, consolidation or merger complies with the requirements of this Indenture.

-88-

In case of any such consolidation, merger, sale or conveyance and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the Note Guarantee and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Guarantor, such successor Person shall succeed to and be substituted for the Guarantor with the same effect as if it had been named herein as a Guarantor. All the Note Guarantees so issued shall in all respects have the same legal rank and benefit under this Indenture as the Note Guarantees theretofore and thereafter issued in accordance with the terms of this Indenture as though all such Note Guarantees had been issued at the date of the execution hereof.

Except as set forth in Articles IV and V hereof, and notwithstanding clauses (1) and (2) above, nothing contained in this Indenture or in any of the Notes shall prevent any consolidation or merger of a Guarantor with or into the Issuer or another Guarantor, or shall 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.

SECTION 10.6 Releases Following Sale of Assets.

In the event of a sale or other transfer or disposition of all of the Capital Interests in any Guarantor to any Person that is not an Affiliate of the Company in compliance with the terms of this Indenture, or in the event all or substantially all the assets or Capital Interests of a Guarantor are sold or otherwise transferred, by way of merger, consolidation or otherwise, to a Person that is not an Affiliate of the Company in compliance with the terms of this Indenture, then such Guarantor (or the Person concurrently acquiring such assets of such Guarantor) shall be deemed automatically and unconditionally released and discharged of any obligations under this Note Guarantee in support thereof, as evidenced by a supplemental indenture executed by the Company, the Guarantors and the Trustee, without any further action on the part of the Trustee or any Holder.

Any Guarantor not released from its obligations under this Note Guarantee shall 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 X.

SECTION 10.7 Release of a Guarantor.

Any Guarantor that is designated by the Board of Directors of the Company as an Unrestricted Subsidiary in accordance with the terms of this Indenture shall, at such time, be deemed automatically and unconditionally released and discharged of its obligations under its Note Guarantee without any further action on the part of the Trustee or any Holder. The Trustee shall deliver an appropriate instrument evidencing such release upon receipt of the Company’s request for such release accompanied by an Officers’ Certificate certifying as to the compliance with this Section 10.7. Any Guarantor not so released shall remain liable for the full amount of principal of and interest on the Notes as provided in its Note Guarantee.

-89-

SECTION 10.8 Benefits Acknowledged.

Each Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by this Indenture and that its Guarantee and waivers pursuant to its Note Guarantee are knowingly made in contemplation of such benefits.

SECTION 10.9 Future Guarantors.

Each Person that is required to become a Guarantor after the Issue Date pursuant to Section 4.14 shall promptly execute and deliver to the Trustee a supplemental indenture pursuant to which such Person shall become a Guarantor. In addition to such supplemental indenture, each Person that is required to become a Guarantor after the Issue Date shall promptly execute and deliver to the Trustee a notation of Note Guarantee substantially in the form attached hereto as Exhibit B. Concurrently with the execution and delivery of such supplemental indenture and Note Guarantee, the Company shall deliver to the Trustee an Opinion of Counsel and an Officers’ Certificate to the effect that such supplemental indenture has been duly authorized, executed and delivered by such Person and that, subject to the application of bankruptcy, insolvency, moratorium, fraudulent conveyance or transfer and other similar laws relating to creditors’ rights generally and to the principles of equity, whether considered in a proceeding at law or in equity, the Guarantee of such Guarantor is a legal, valid and binding obligation of such Guarantor, enforceable against such Guarantor in accordance with its terms and/or to such other matters as the Trustee may reasonably request.

MANTECH INTERNATIONAL CORPORATION

Capitalized terms used herein shall have the meanings assigned to them in the Indenture referred to below unless otherwise indicated.

(1) Interest.

(a) ManTech International Corporation, a Delaware corporation, or its successor (together, “ManTech”), promises to pay interest on the principal amount of this Note (the “Notes”) at a fixed rate. ManTech will pay interest in United States dollars (except as otherwise provided herein) semiannually in arrears on April 15 and October 15 of each year, commencing on October 15, 2010 or, if any such day is not a Business Day, on the next succeeding Business Day (each an “Interest Payment Date”). Interest on the Notes shall accrue from the most recent date to which interest has been paid or, if no interest has been paid, from and including April 13, 2010; provided that if there is no existing Default or Event of Default in the payment of interest, and if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date (but after April 13, 2010), interest shall accrue from such next succeeding Interest Payment Date, except in the case of the original issuance of the Notes, in which case interest shall accrue from the date of authentication. ManTech shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal at the rate equal to 1% per annum in excess of the then applicable interest rate on the Notes to the extent lawful; it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace period) at the same rate to the extent lawful. Interest shall be computed on the basis of a 360-day year comprised of twelve 30-day months. The interest rate on the Notes will in no event be higher than the maximum rate permitted by New York law as the same may be modified by United States law of general application.

[(b) Registration Rights Agreement. The Holder of this Note is entitled to the benefits of a Registration Rights Agreement, dated as of April 13, 2010, among the Issuer, the Guarantors party thereto and the Initial Purchasers.]¹

(2) Method of Payment. ManTech will pay interest on the Notes (except defaulted interest) on the applicable Interest Payment Date to the Persons who are registered Holders of the Notes at the close of business on the April 1 and October 1 preceding the Interest Payment Date, even if such Notes are cancelled after such record date and on or before such Interest Payment Date, except as provided in Section 2.12 of the Indenture with respect to defaulted interest. If an

A-5

Interest Payment Date falls on a day that is not a Business Day, the applicable interest payment will be made on the next Business Day as if it were the date of payment (and without any interest or other payment in respect of any such delay), except that, if such Business Day is in the next succeeding calendar year, such payment shall be made on the immediately preceding Business Day, in each case with the same force and effect as if made on such date. The Notes shall be payable as to principal, premium and interest at the office or agency of ManTech maintained for such purpose within or without the City and State of New York, or, at the option of ManTech, payment of interest may be made by check mailed to the Holders at their addresses set forth in the register of Holders; provided that payment by wire transfer of immediately available funds shall be required with respect to principal of, premium, if any, and interest on, all Global Notes and all other Notes the Holders of which shall have provided written wire transfer instructions to ManTech and the Paying Agent. Such payment shall be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts.

Any payments of principal of and interest on this Note prior to Stated Maturity shall be binding upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange hereof or in lieu hereof, whether or not noted hereon. The amount due and payable at the maturity of this Note shall be payable only upon presentation and surrender of this Note at an office of the Trustee or the Trustee’s agent appointed for such purposes.

(3) Paying Agent and Registrar. Initially, The Bank of New York Mellon Trust Company, N.A., the Trustee under the Indenture, shall act as Paying Agent and Registrar. ManTech may change any Paying Agent or Registrar without notice to any Holder. ManTech or any of its Restricted Subsidiaries may act in any such capacity.

(4) Indenture. ManTech issued the Notes under an Indenture, dated as of April 13, 2010 (the “Indenture”), among ManTech, the Guarantors and the Trustee. The terms of the Notes include those stated in the Indenture and those made a part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S. Code §§ 77aaa-77bbbb) (the “TIA”). To the extent the provisions of this Note are inconsistent with the provisions of the Indenture, the Indenture shall govern.

(3) except as permitted by the Indenture, any Note Guarantee of any Significant Subsidiary (or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary) shall for any reason cease to be, or it shall be asserted by any Guarantor or ManTech not to be, in full force and effect and enforceable in accordance with its terms;

(4) default in the performance, or breach, of any covenant or agreement of ManTech or any Guarantor in the Indenture (other than a covenant or agreement a default in whose performance or whose breach is specifically dealt with in clause (1), (2) or (3) above), and continuance of such default or breach for a period of 60 days after written notice thereof (or 120 days in the case of the covenant described under Section 4.3 of the Indenture) has been given to ManTech by the Trustee or to ManTech and the Trustee by the Holders of at least 25% in aggregate principal amount of the outstanding Notes;

A-10

(6) the entry against ManTech or any Restricted Subsidiary that is a Significant Subsidiary of a final judgment or final judgments for the payment of money in an aggregate amount in excess of $50.0 million, by a court or courts of competent jurisdiction, which judgments remain undischarged, unwaived, unstayed, unbonded or unsatisfied for a period of 60 consecutive days; or

(7) (i) ManTech, any Restricted Subsidiary that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken as a whole, would constitute a Significant Subsidiary, pursuant to or within the meaning of any Bankruptcy Law:

(a) commences a voluntary case,

(b) consents to the entry of an order for relief against it in an involuntary case,

(d) makes a general assignment for the benefit of its creditors, or

(e) generally is not paying its debts as they become due; or

(ii) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that:

(a) is for relief against ManTech or any Restricted Subsidiary that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary, in an involuntary case;

(b) appoints a custodian of ManTech or any Restricted Subsidiary that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary or for all or substantially all of the property of ManTech or any of its Restricted Subsidiaries; or

(c) orders the liquidation of ManTech or any Restricted Subsidiary that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary;

and the order or decree remains unstayed and in effect for 60 consecutive days.

If an Event of Default (other than an Event of Default specified in clause (7) above with respect to ManTech) occurs and is continuing, then and in every such case the Trustee or the Holders of not less than 25% in aggregate principal amount of the outstanding Notes may declare the principal of the Notes and any accrued interest on the Notes to be due and payable immediately

A-11

by a notice in writing to ManTech (and to the Trustee if given by Holders); provided, however, that after such acceleration, but before a judgment or decree based on acceleration, the Holders of a majority in aggregate principal amount of the outstanding Notes may, under certain circumstances, rescind and annul such acceleration if all Events of Default, other than the nonpayment of accelerated principal of or interest on the Notes, have been cured or waived as provided in the Indenture.

In the event of a declaration of acceleration of the Notes solely because an Event of Default described in clause (5) above has occurred and is continuing, the declaration of acceleration of the Notes shall be automatically rescinded and annulled if the Event of Default or payment default triggering such Event of Default pursuant to clause (5) shall be remedied or cured by ManTech or a Restricted Subsidiary of ManTech or waived by the holders of the relevant Debt within 20 Business Days after the declaration of acceleration with respect thereto and if the rescission and annulment of the acceleration of the Notes would not conflict with any judgment or decree of a court of competent jurisdiction obtained by the Trustee for the payment of amounts due on the Notes.

If an Event of Default specified in clause (7) above occurs with respect to ManTech, the principal of and any accrued interest on the Notes then outstanding shall ipso facto become immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. For further information as to waiver of defaults, see Article IX of the Indenture. The Trustee may withhold from Holders notice of any Default (except Default in payment of principal of, premium, if any, and interest) if the Trustee determines that withholding notice is in the interest of the Holders to do so.

(13) Trustee Dealings with ManTech. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for ManTech, the Guarantors or their respective Affiliates, and may otherwise deal with ManTech, the Guarantors or their respective Affiliates, as if it were not the Trustee.

(14) No Recourse Against Others. No director, officer, employee, stockholder, general or limited partner or incorporator, past, present or future, of ManTech, the Guarantors or any of their respective Subsidiaries, as such or in such capacity, shall have any personal liability for any obligations of the Issuer under the Notes, any Guarantee or the Indenture by reason of his, her or its status as such director, officer, employee, stockholder, general or limited partner or incorporator.

No recourse may, to the full extent permitted by applicable law, be taken, directly or indirectly, with respect to the obligations of ManTech or the Guarantors on the Notes or under the Indenture or any related documents, any certificate or other writing delivered in connection therewith, against (i) the Trustee in its individual capacity, or (ii) any partner, owner, beneficiary, agent, officer, director, employee, agent, successor or assign of the Trustee, each in its individual capacity, or (iii) any holder of equity in the Trustee.

Each Holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Notes.
