If required by the Trustee or the Company, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Trustee and the Company to protect the Company, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Company may charge for their expenses in replacing a Note. If, after the delivery of such replacement Note, a bona fide purchaser of the original Note in lieu of which such replacement Note was issued presents for payment or registration such original Note, the Trustee shall be entitled to recover such replacement Note from the Person to whom it was delivered or any Person taking therefrom, except a bona fide purchaser, and shall be entitled to recover upon the security or indemnity provided therefor to the extent of any loss, damage, cost or expense incurred by the Company, the Trustee and any Agent in connection therewith.

Except as set forth in Section 2.10 hereof, a Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note.

(b) If a Note is replaced pursuant to Section 2.08 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a protected purchaser.

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

(d) If the Paying Agent (other than the Company, a Subsidiary of the Company or an Affiliate of any of the foregoing) 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 2.10. Treasury Notes. In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Company, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company, 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 that the Trustee knows are so owned shall be so disregarded.

Section 2.11. Temporary Notes. (a) Until certificates representing Notes are ready for delivery, the Company may prepare and the Trustee, upon receipt of an Authentication Order, shall authenticate temporary Notes. Temporary Notes shall be substantially in the form of Definitive Notes but may have variations that the Company considers appropriate for temporary Notes and as shall be reasonably acceptable to the Trustee. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate Definitive Notes in exchange for temporary Notes.

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

Section 2.13. Defaulted Interest. If the Company 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 the record date for the interest payment or a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01 hereof.

Section 2.14. CUSIP Numbers. The Company in issuing the Notes may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in or omission of such numbers.

In the case of a Redemption of the Notes pursuant to Section 3.07(b) hereof the Trustee shall select the Notes to be redeemed on a pro rata basis or on as nearly a pro rata basis as practicable (subject to the procedures of DTC or any other depositary). In the event of partial redemption by lot, the particular Notes to be redeemed shall be selected, unless otherwise provided herein, not less than 60 nor more than 90 days prior to the redemption date by the Trustee from the outstanding Notes not previously called for redemption.

(b) The Trustee shall promptly notify the Company in writing of the Notes selected for redemption and, in the case of any Note selected for partial redemption, the principal amount at maturity thereof to be redeemed. No Notes in amounts of $1,000 or less shall be redeemed in part. The Trustee may select for redemption portions of the principal of Notes that have denominations larger than

$1,000. Notes and portions of Notes selected shall be in amounts of $1,000 or whole multiples of $1,000 in excess thereof; except that if all of the Notes of a Holder are to be redeemed, the entire outstanding amount of Notes held by such Holder, even if not a multiple of $1,000, shall be redeemed. Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption.

Section 3.03. Notice of Redemption.

(a) At least 30 days but not more than 60 days before a redemption date, the Company shall mail or cause to be mailed, by first class mail, a notice of redemption to each Holder whose Notes are to be redeemed at its registered address and send a copy to the Trustee at the same time.

The notice shall identify the Notes (including CUSIP number(s)) to be redeemed and shall state:

(i) the redemption date;

(ii) the redemption price;

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

(iv) the name and address of the Paying Agent;

(v) that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price and become due on the date fixed for redemption;

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

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

the Company shall have delivered to the Trustee, at least 45 days prior to the redemption date (unless the Trustee shall have agreed to a shorter period), an Officers’ Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph. The notice, if mailed in the manner provided herein shall be presumed to have been given, whether or not the Holder receives such notice.

Section 3.04. Effect of Notice of Redemption. Once notice of redemption is mailed in accordance with Section 3.03 hereof, Notes called for redemption become irrevocably due and payable on the redemption date at the redemption price. A notice of redemption may not be conditional other than in the case of a Change of Control Offer pursuant to 4.19 hereof.

Section 3.05. Deposit of Redemption Price. (a) Prior to 1:00 p.m. New York Time on the Business Day that is the redemption date, the Company shall deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption price of and accrued interest on all Notes to be redeemed on that date. The Trustee or the Paying Agent shall promptly return to the Company any money deposited with the Trustee or the Paying Agent by the Company in excess of the amounts necessary to pay the redemption price of, and accrued interest on, all Notes to be redeemed.

(b) If the Company complies with the provisions of the preceding paragraph, on and after the redemption date, interest shall cease to accrue on the Notes or the portions of Notes called for redemption. If a Note is redeemed on or after an interest record date but on or prior to the related interest payment date, then any accrued and unpaid interest shall be paid to the Holder 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 Company to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01 hereof.

Section 3.06. Notes Redeemed in Part. Upon surrender of a Note that is redeemed in part, the Company shall issue and the Trustee shall authenticate for the Holder at the expense of the Company a new Note equal in principal amount to the unredeemed portion of the Note surrendered.

At least 65% of the aggregate principal amount of Notes (including the principal amount of any Additional Notes issued under this Indenture) must remain outstanding immediately after the occurrence of such redemption. In order to effect this redemption, the Company must mail a notice of redemption no later than 60 days after the closing of the related Equity Offering and must complete such redemption within 90 days of the closing of the Equity Offering.

(c) Any redemption pursuant to this Section 3.07 shall be made pursuant to the provisions of Sections 3.01 through 3.06 hereof.

(b) in the case of the redesignation of an Unrestricted Subsidiary as a Restricted Subsidiary (as long as the designation of such Subsidiary as an Unrestricted Subsidiary was deemed a Restricted Payment), the Fair Market Value of the Company’s interest in such Subsidiary at the time of such redesignation; and

(F) any amount which previously qualified as a Restricted Payment on account of any guarantee entered into by the Company or any Restricted Subsidiary; provided that such guarantee has not been called upon and the obligation arising under such guarantee no longer exists.

(b) Notwithstanding the foregoing, any Lien, assignment or conveyance securing the Notes or a Guarantee granted pursuant to paragraph (a) of this Section 4.10 shall be automatically and unconditionally released and discharged upon: (i) any sale, exchange or transfer to any Person not an Affiliate of the Company of the property or assets secured by such Lien, (ii) any sale, exchange or transfer to any Person not an Affiliate of the Company of all of the Capital Stock held by the Company or any Restricted Subsidiary in, or all or substantially all the assets of, any Restricted Subsidiary creating such Lien, or (iii) with respect to any Lien, assignment or conveyance securing a Guarantee, the release of such Guarantee in accordance with this Indenture.

Section 4.11. Asset Sales.

(a) The Company shall not, and shall not permit any Restricted Subsidiary to, consummate any Asset Sale, other than an Excluded Asset Sale or Qualified Exchangeable Sale, unless (i) the Company or such Restricted Subsidiary, as the case may be, receives consideration at the time of such Asset Sale at least equal to the Fair Market Value of the assets and property subject to such Asset Sale and (ii) at least 75% of the consideration paid to the Company or such Restricted Subsidiary in connection with such Asset Sale is in the form of cash, Cash Equivalents, Liquid Securities, Exchanged Properties (including pursuant to asset swaps) or the assumption by the purchaser of liabilities of the Company (other than liabilities of the Company that are by their terms subordinated to the Notes) or liabilities of any Guarantor that made such Asset

Sale (other than liabilities of a Guarantor that are by their terms subordinated to such Guarantor’s Guarantee), or any combination of the foregoing, in each case as a result of which the Company and its remaining Restricted Subsidiaries are no longer liable for such liabilities, or, solely in the case of any Asset Sale of Production Facility or Pipeline Assets, Permitted MLP Securities; provided, that any Asset Sale pursuant to a condemnation, appropriation or other similar taking, including by deed in lieu of condemnation, or pursuant to the foreclosure or other enforcement of a Lien incurred not in breach of Section 4.10 hereof or exercise by the related lienholder of rights with respect thereto, including by deed or assignment in lieu of foreclosure shall not be required to satisfy the conditions set forth in clauses (i) and (ii) of this paragraph (a) (“Permitted Consideration”).

(b) Within 365 days after the receipt by the Company or a Restricted Subsidiary of Net Available Cash from an Asset Sale, other than an Excluded Asset Sale or Qualified Exchangeable Sale, such Net Available Cash may be applied by the Company or such Restricted Subsidiary, to the extent the Company or such Restricted Subsidiary elects (or is required by the terms of any Pari Passu Indebtedness of the Company or a Restricted Subsidiary), to

(1) prepay or repay Indebtedness of the Company under any Credit Facility;

(2) reinvest in Additional Assets (including by means of an Investment in Additional Assets by a Restricted Subsidiary with Net Available Cash received by the Company or another Restricted Subsidiary) or make capital expenditures in a Permitted Business; or

(3) purchase Notes, or purchase or repay on a permanent basis other Indebtedness (excluding (i) any Subordinated Indebtedness and (ii) any Notes or other Indebtedness owned by the Company or an Affiliate of the Company);

provided, that the Company or the applicable Restricted Subsidiary will be deemed to have complied with clause (2) of this paragraph (b) if, within 365 days of such Asset Sale, the Company or such Restricted Subsidiary shall have commenced and not completed or abandoned an expenditure or Investment, or a binding agreement with respect to an expenditure or Investment, in compliance with such clause (2), and that expenditure or Investment is substantially completed within a date one year and six months after the date of such Asset Sale, and; provided further, that if any Net Cash Proceeds from such Asset Sale attributable to Capital Stock, property, assets or rights used in or constituting part of the Contracting Services Business of the Company or any Restricted Subsidiary, other than Production Facility or Pipeline Assets, is applied pursuant to clause (2) of this paragraph (b) to reinvest in Additional Assets or make capital expenditures in the Oil and Gas Business, then at least an equal amount of Net Cash Proceeds from such Asset Sale shall be used to reinvest in Additional Assets or make capital expenditures in the Contracting Services Business within such

365 day (or one year and six months, as the case may be) period. Pending the final application of any such Net Available Cash, the Company may temporarily reduce Indebtedness under any Credit Facility or otherwise expend or invest such Net Available Cash in any manner that is not prohibited by this Indenture.

(c) Any Net Available Cash from an Asset Sale, other than an Excluded Asset Sale or Qualified Exchangeable Sale, not applied in accordance paragraph (b) of this Section 4.11 within 365 days (or within one year and six months as the case may be) from the date of such Asset Sale shall constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $20.0 million, the Company will be required to make an offer to purchase Notes having an aggregate principal amount equal to the aggregate amount of Excess Proceeds (the “Prepayment Offer”) at a purchase price equal to 100% of the principal amount of such Notes plus accrued and unpaid interest, if any, to the Asset Sale Purchase Date (as defined in paragraph (d) of this Section 4.11) in accordance with the procedures (including prorating in the event of over subscription) set forth in this Indenture, but, if the terms of any Pari Passu Indebtedness require that a Pari Passu Offer be made contemporaneously with the Prepayment Offer, then the Excess Proceeds shall be prorated between the Prepayment Offer and such Pari Passu Offer in accordance with the aggregate outstanding principal amounts of the Notes and such Pari Passu Indebtedness, and the aggregate principal amount of Notes for which the Prepayment Offer is made shall be reduced accordingly. If the aggregate principal amount of Notes tendered by Holders thereof exceeds the amount of available Excess Proceeds, then such Excess Proceeds will be allocated pro rata according to the principal amount of the Notes tendered and the Trustee will select the Notes to be purchased in accordance with this Indenture. To the extent that any portion of the amount of Excess Proceeds remains after compliance with the second sentence of this paragraph (c) and provided that all Holders of Notes have been given the opportunity to tender their Notes for purchase as described in paragraph (d) of this Section 4.11 in accordance with this Indenture, the Company and its Restricted Subsidiaries may use such remaining amount for purposes not prohibited by this Indenture and the amount of Excess Proceeds will be reset to zero.

(d) Within 30 days after the 365th day following, or the date one year and six months following, the date of an Asset Sale (as the case may be), the Company shall, if it is obligated to make an offer to purchase the Notes pursuant to paragraph (c) of this Section 4.11, send a written Prepayment Offer notice, by first-class mail, to the Holders of the Notes (the “Prepayment Offer Notice”), accompanied by such information regarding the Company and its Subsidiaries as the Company believes will enable such Holders of the Notes to make an informed decision with respect to the Prepayment Offer. The Prepayment Offer Notice will state, among other things:

(1) that the Company is offering to purchase Notes pursuant to the provisions of this Indenture;

(2) that any Note (or any portion thereof) accepted for payment (and duly paid on the Asset Sale Purchase Date) pursuant to the Prepayment Offer shall cease to accrue interest on the Asset Sale Purchase Date;

(3) that any Notes (or portions thereof) not properly tendered will continue to accrue interest;

(4) the purchase price and purchase date, which shall be, subject to any contrary requirements of applicable law, no less than 30 days nor more than 60 days after the date the Prepayment Offer Notice is mailed (the “Asset Sale Purchase Date”);

(5) the aggregate principal amount of Notes to be purchased;

(6) a description of the procedure which Holders of Notes must follow in order to tender their Notes and the procedures that Holders of Notes must follow in order to withdraw an election to tender their Notes for payment; and

(7) all other instructions and materials necessary to enable Holders to tender Notes pursuant to the Prepayment Offer.

(e) The Company shall comply, to the extent applicable, with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws or regulations thereunder to the extent such laws and regulations are applicable in connection with the purchase of Notes as described above. To the extent that the provisions of any securities laws or regulations conflict with the provisions relating to the Prepayment Offer, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.11 by virtue thereof.

(f) Holders electing to have Notes purchased hereunder will be required to surrender such Notes at the address specified in the notice prior to the Asset Sale Purchase Date. Holders will be entitled to withdraw their election to have their Notes purchased pursuant to this Section 4.11 if the Company receives, not later than one Business Day prior to the Asset Sale Purchase Date, a telegram, telex, facsimile transmission or letter setting forth (i) the name of the Holder, (ii) the certificate number of the Note in respect of which such notice of withdrawal is being submitted, (iii) the principal amount of the Note (which shall be $1,000 or whole multiples of $1,000 in excess thereof) delivered for purchase by the Holder as to which his election is to be withdrawn, (iv) a statement that such Holder is withdrawing his election to have such principal amount of such Note purchased, and (v) the principal amount, if any, of such Note (which shall be $1,000 or whole multiples of $1,000 in excess thereof) that remains subject to the original Prepayment Offer Notice and that has been or will be delivered for purchase by the Company.

(g) The Company shall (i) not later than the Asset Sale Purchase Date accept for payment Notes or portions thereof (in amounts of $1,000 or whole multiples of $1,000 in excess thereof) tendered pursuant to the Prepayment Offer, (ii) not later than 1:00 p.m. (New York time) on the Asset Sale Purchase Date deposit with the Trustee or with a Paying Agent an amount of money in same day funds sufficient to pay the aggregate Prepayment Offer Price, as the case may be, of all the Notes or portions thereof (in amounts of $1,000 or whole multiples of $1,000 in excess thereof) which are to be purchased on that date and (iii) not later than 1:00 p.m. (New York time) on the Asset Sale Purchase Date, as the case may be, deliver to the Paying Agent an Officers’ Certificate stating the Notes or portions thereof accepted for payment by the Company. The Paying Agent shall promptly mail or deliver to Holders of Notes so accepted payment in an amount equal to the Prepayment Offer Price of the Notes purchased from each such Holder, and the Company shall execute and the Trustee shall promptly authenticate and mail or deliver to such Holders a new Note equal in principal amount to any unpurchased portion of the Note surrendered. Any Notes not so accepted shall be promptly mailed or delivered by the Paying Agent at the Company’s expense to the Holder thereof. For purposes of this Section 4.11, the Company shall choose a Paying Agent which shall not be the Company.

The Trustee and the Paying Agent shall return to the Company, upon its request, any cash that remains unclaimed for two years after an Asset Sale Purchase Date, together with interest, if any, thereon (subject to Section 7.01(f)), held by them for the payment of the Prepayment Offer Price, as the case may be; and the Holder of such tendered and accepted Note shall thereafter look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such cash, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, shall at the expense of the Company cause to be published once in The New York Times and The Wall Street Journal (national edition) or send to each Holder entitled to such money 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 Company; provided, further however, that (x) to the extent that the aggregate amount of cash deposited by the Company with the Trustee in respect of a Prepayment Offer, as the case may be, exceeds the aggregate Prepayment Offer Price of the Notes or portions thereof to be purchased, then the Trustee shall hold such excess for the Company and (y) unless otherwise directed by the Company in writing, promptly after the Business Day following the Asset Sale Purchase Date, as the case may be, the Trustee shall return any such excess to the Company together with interest or dividends, if any, thereon (subject to Section 7.01(f)).

(h) Notes to be purchased shall, on the Asset Sale Purchase Date, become due and payable at the Prepayment Offer Price, as the case may be, and

from and after such date (unless the Company shall default in the payment of the Prepayment Offer Price) such Notes shall cease to bear interest. Such Prepayment Offer Price shall be paid to such Holder promptly following the later of the Asset Sale Purchase Date and the time of delivery of such Note to the relevant Paying Agent at the office of such Paying Agent by the Holder thereof in the manner required. Upon surrender of any such Note for purchase in accordance with the foregoing provisions, such Note shall be paid by the Company at the Prepayment Offer Price; provided, however, that installments of interest whose Stated Maturity is on or prior to the Asset Sale Purchase Date shall be payable to the Person in whose name the Notes are registered as such on the relevant record dates according to the terms and the provisions of Section 2.03; provided further that Notes to be purchased are subject to proration in the event the Excess Proceeds are less than the aggregate Prepayment Offer Price of all Notes tendered for purchase, with such adjustments as may be appropriate by the Trustee so that only Notes in denominations of $1,000 or whole multiples of $1,000 in excess thereof, shall be purchased. If any Note tendered for purchase shall not be so paid upon surrender thereof by deposit of funds with the Trustee or a Paying Agent in accordance with paragraph (g) of this Section 4.11, the principal thereof (and premium, if any, thereon) shall, until paid, bear interest from the Asset Sale Purchase Date at the rate borne by such Note. Any Note that is to be purchased only in part shall be surrendered to a Paying Agent at the office of such Paying Agent (with, if the Company, the Registrar or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Registrar or the Trustee duly executed by, the Holder thereof or such Holder’s attorney duly authorized in writing), and the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Note, without service charge, one or more new Notes of any authorized denomination as requested by such Holder in an aggregate principal amount equal to, and in exchange for, the portion of the principal amount of the Note so surrendered that is not purchased. The Company shall publicly announce the results of the Prepayment Offer, as the case may be, on or as soon as practicable after the Asset Sale Purchase Date.

Section 4.12. Issuances Of Guarantees By Restricted Subsidiaries.

(a) The Company shall provide to the Trustee, on or prior to the 90th day after the date that (i) any Person becomes a Restricted Subsidiary after the date of this Indenture other than an MLP Entity or Kommandor LLC, (ii) any Unrestricted Subsidiary is redesignated as a Restricted Subsidiary, or (iii) any Restricted Subsidiary of the Company (which is not a Guarantor) becomes a guarantor or obligor in respect of any Indebtedness of the Company or any of the Restricted Subsidiaries (other than the guarantee by the Company of any Permitted Debt of Kommandor LLC), in each case, a supplemental indenture to the Indenture, executed by such Restricted Subsidiary, providing for a full and unconditional guarantee on a senior unsecured basis by such Restricted Subsidiary

of the Company’s obligations under the Notes and this Indenture to the same extent as that set forth in this Indenture.

(b) Notwithstanding the foregoing (i) no Foreign Subsidiary shall be required to execute any such supplemental indenture unless such Foreign Subsidiary has guaranteed other Indebtedness of the Company or of a Restricted Subsidiary that is not a Foreign Subsidiary, and (ii) no Non-Guarantor Restricted Subsidiary (other than Cal Dive I-Title XI, Inc.) shall be required to execute any such supplemental indenture if the Consolidated Net Worth of such Non-Guarantor Restricted Subsidiary, together with the Consolidated Net Worth of all other Non-Guarantor Restricted Subsidiaries (other than and without regard to Cal Dive I-Title XI, Inc.), as of such date, does not exceed in the aggregate $25.0 million; provided, however, that to the extent the collective Consolidated Net Worth of the Company’s Non-Guarantor Restricted Subsidiaries (other than and without regard to Cal Dive I-Title XI, Inc.), as of the date of the creation of, acquisition of or Investment in a Non-Guarantor Restricted Subsidiary, exceeds $25.0 million, the Company shall cause, within 60 days after such date, one or more of such Non-Guarantor Restricted Subsidiaries to similarly execute and deliver to the Trustee a supplemental indenture to this Indenture substantially in the form of Exhibit E hereto providing for a full and unconditional guarantee on a senior unsecured basis by such Restricted Subsidiary of the Company’s obligations under the Notes and this Indenture to the same extent as that set forth in such Indenture, such that the collective Consolidated Net Worth of all remaining Non-Guarantor Restricted Subsidiaries (other than and without regard to Cal Dive I-Title XI, Inc.) does not exceed $25.0 million provided, further, however, it is understood that Cal Dive I-Title XI, Inc. will only become a Guarantor pursuant to clause (iii) of paragraph (a) of this Section 4.12.

Section 4.13. Limitation on Issuances and Sales of Preferred Stock of Restricted Subsidiaries.

(a) The Company shall not permit any Restricted Subsidiary of the Company to issue, sell or transfer any Preferred Stock of such Restricted Subsidiary, except for (1) Preferred Stock issued or sold to, held by or transferred to the Company or a Wholly Owned Restricted Subsidiary or a Guarantor, and (2) Preferred Stock issued by a Person prior to the time (A) such Person becomes a Restricted Subsidiary, (B) such Person merges with or into a Restricted Subsidiary or (C) a Restricted Subsidiary merges with or into such Person; provided that such Preferred Stock was not issued or incurred by such Person in anticipation of the type of transaction contemplated by subclause (A), (B) or (C) of this paragraph (a). This paragraph (a) shall not apply upon the acquisition of all the outstanding Capital Stock of such Restricted Subsidiary in accordance with the terms of this Indenture.

(b) The Company shall not permit any Person (other than the Company or a Wholly Owned Restricted Subsidiary or a Guarantor) to acquire Preferred Stock of any Restricted Subsidiary from the Company or any Restricted

Subsidiary, except upon the acquisition of all the outstanding Capital Stock of such Restricted Subsidiary in accordance with the terms of this Indenture.

Section 4.14. Dividend and other Payment Restrictions Affecting Restricted Subsidiaries.

(a) The Company shall not, and shall not cause or permit any of its Restricted Subsidiaries to, directly or indirectly, create or otherwise cause to come into existence or become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary to:

(1) pay dividends or make any other distribution on its Capital Stock to the Company or any other Restricted Subsidiary;

(2) pay any Indebtedness owed to the Company or any other Restricted Subsidiary;

(3) make loans or advances to the Company or any other Restricted Subsidiary; or

(4) transfer any of its properties or assets to the Company or any other Restricted Subsidiary.

(b) However, paragraph (a) of this Section 4.14 shall not prohibit any encumbrance or restriction created, existing or becoming effective under or by reason of:

(1) any agreement (including the Senior Credit Agreement and the other Indenture) in effect on the date of this Indenture;

(2) any agreement or instrument with respect to a Restricted Subsidiary that is not a Restricted Subsidiary of the Company on the date of the Indenture, in existence at the time such Person becomes a Restricted Subsidiary of the Company and not incurred in connection with, or in contemplation of, such Person becoming a Restricted Subsidiary; provided that such encumbrances and restrictions are not applicable to the Company or any Restricted Subsidiary or the properties or assets of the Company or any Restricted Subsidiary other than such Subsidiary which is becoming a Restricted Subsidiary;

(3) any agreement or instrument governing any Acquired Debt or other agreement of any entity or related to assets acquired by or merged into or consolidated with the Company or any Restricted Subsidiaries, so long as such encumbrance or restriction (A) was not entered into in contemplation of the acquisition, merger or consolidation transaction, and (B) is not applicable to any Person, or the properties or assets of any Person, other than the Person, or the property or assets or subsidiaries of

the Person, so acquired, so long as the agreement containing such restriction does not violate any other provision of this Indenture;

(4) any applicable law or any requirement of any regulatory body;

(5) any agreement in relation to any Liens securing obligations or Indebtedness (provided such Liens are otherwise permitted to be incurred under the provisions of Section 4.10 hereof) that limit the right of the debtor to dispose of or otherwise transfer the assets subject to such Liens;

(6) provisions restricting subletting or assignment of any lease governing a leasehold interest of the Company or any Restricted Subsidiary, or restrictions in licenses relating to the property covered thereby, or other encumbrances or restrictions in agreements or instruments relating to specific assets or property that restrict generally the transfers of such assets or property; provided, however, that such encumbrances or restrictions do not materially impair the ability of the Company to make scheduled payments on the Notes when due;

(7) agreements with respect to asset or Capital Stock sales, which limit the transfer of such assets or Capital Stock pending the closing of such sale;

(8) shareholders’, partnership, joint venture and similar agreements entered into in the ordinary course of business; provided, however, that such encumbrances or restrictions do not apply to any Restricted Subsidiaries other than the applicable company, partnership, joint venture or other entity; and provided, further, however, that such encumbrances and restrictions do not materially impair the ability of the Company to make scheduled payments on the Notes when due;

(9) cash or other deposits, or net worth requirements or similar requirements, imposed by suppliers or landlords under contracts entered into in the ordinary course of business;

(10) any other Credit Facility governing debt of the Company, any Guarantor or any Foreign Subsidiary, permitted to be incurred under the provisions of Section 4.07 hereof provided, however, that such encumbrances or restrictions (i) are not materially more restrictive, taken as a whole, than those contained in the Senior Credit Agreement or (ii) do not (except upon a default or event of default thereunder) restrict the payment of dividends in an amount sufficient to materially impair the ability of the Company to make scheduled payments on the Notes when due;

(11) restrictions of the nature described in clause (4) of paragraph (a) of this Section 4.14 by reason of customary non-assignment provisions in contracts, agreements, licenses and leases entered into in the ordinary course of business; and

(12) any amendment, modification, restatement, renewal, increase, supplement, refunding, replacement or refinancing of any agreement, requirement, provision, instrument or document containing the encumbrances or restrictions in the foregoing clauses (1) through (11), or in this clause (12); provided that the terms and conditions of any such encumbrances or restrictions are no more restrictive in any material respect taken as a whole than those under or pursuant to such agreement, requirement, provision, instrument or document so affected.

Section 4.15. Sale Leaseback Transactions.

The Company shall not, and shall not permit any of its Restricted Subsidiaries to, enter into any Sale Leaseback Transaction; provided, that the Company or any of its Restricted Subsidiaries may enter into a Sale Leaseback Transaction if:

(1) the Company or such Subsidiary could have incurred Indebtedness in an amount equal to the Attributable Indebtedness relating to such Sale Leaseback Transaction pursuant to the Consolidated Fixed Charge Coverage Ratio test set forth in paragraph (a) of Section 4.07 hereof;

(2) the gross cash proceeds of such Sale Leaseback Transaction are at least equal to the Fair Market Value of the property that is the subject of such Sale Leaseback Transaction; and

(3) the transfer of assets in such Sale Leaseback Transaction is permitted by, and the Company applies the proceeds of such transaction in the same manner and to the same extent as Net Available Cash and Excess Proceeds from an Asset Sale in compliance with, Section 4.11 hereof.

Section 4.16. Lines of Business.

Neither the Company nor any of its Restricted Subsidiaries will directly or indirectly engage in any material respect in any line or lines of business activity other than that which is a Permitted Business.

Section 4.17. Unrestricted Subsidiaries.

Each of Cal Dive and its Subsidiaries shall initially be designated as an “Unrestricted Subsidiary”. The Board of Directors of the Company may

designate after the Issue Date any other Subsidiary as an “Unrestricted Subsidiary” under this Indenture (a “Designation”) only if:

(a) no Default or Event of Default shall have occurred and be continuing at the time of or after giving effect to such Designation;

(b) (x) the Company would be permitted to make an Investment (other than a Permitted Investment) at the time of Designation (assuming the effectiveness of such Designation) pursuant to paragraph (a) of Section 4.08 hereof in an amount (the “Designation Amount”) equal to the greater of (1) the net book value of the Company’s interest in such Subsidiary calculated in accordance with GAAP or (2) the Fair Market Value of the Company’s interest in such Subsidiary as determined in good faith by the Company’s Board of Directors, or (y) the Designation Amount is less than $1,000.

(c) the Company would be permitted under this Indenture to incur $1.00 of additional Indebtedness (other than Permitted Debt) pursuant to Section 4.07 hereof at the time of such Designation (assuming the effectiveness of such Designation);

(d) such Unrestricted Subsidiary does not own any Capital Stock in any Restricted Subsidiary of the Company which is not simultaneously being designated an Unrestricted Subsidiary;

(e) such Unrestricted Subsidiary is not liable, directly or indirectly, with respect to any Indebtedness other than Unrestricted Subsidiary Indebtedness, provided that an Unrestricted Subsidiary may provide a Guarantee for the Notes; and

(f) such Unrestricted Subsidiary is not a party to any agreement, contract, arrangement or understanding at such time with the Company or any Restricted Subsidiary unless the terms of any such agreement, contract, arrangement or understanding are no less favorable to the Company or such Restricted Subsidiary than those that might be obtained at the time from Persons who are not Affiliates of the Company or, in the event such condition is not satisfied, the value of such agreement, contract, arrangement or understanding to such Unrestricted Subsidiary shall be deemed a Restricted Payment.

In the event of any such Designation, the Company shall be deemed, for all purposes of this Indenture, to have made an Investment equal to the Designation Amount that constitutes a Restricted Payment pursuant to Section 4.08 hereof.

The Company shall not and shall not cause or permit any Restricted Subsidiary to at any time

(a) provide credit support for, guarantee or subject any of its property or assets (other than the Capital Stock of any Unrestricted Subsidiary) to the satisfaction of, any Indebtedness of any Unrestricted Subsidiary (including any undertaking, agreement or instrument evidencing such Indebtedness); provided, however, that this Section 4.17 shall not be deemed to prevent Permitted Investments in Unrestricted Subsidiaries that are otherwise allowed under this Indenture, or

(b) be directly or indirectly liable for any Indebtedness of any Unrestricted Subsidiary.

For purposes of the foregoing, the Designation of a Subsidiary of the Company as an Unrestricted Subsidiary shall be deemed to be the Designation of all present and future Subsidiaries of such Subsidiary as Unrestricted Subsidiaries. Unless so designated as an Unrestricted Subsidiary, any Person that becomes a Subsidiary of the Company will be classified as a Restricted Subsidiary.

The Company may revoke any Designation of a Subsidiary as an Unrestricted Subsidiary (a “Revocation”) if:

(a) no Default or Event of Default shall have occurred and be continuing at the time of and after giving effect to such Revocation;

(b) all Liens and Indebtedness of such Unrestricted Subsidiary outstanding immediately following such Revocation would, if incurred at such time, have been permitted to be incurred for all purposes of this Indenture; and

(c) unless such redesignated Subsidiary shall not have any Indebtedness outstanding (other than Indebtedness that would be Permitted Debt), immediately after giving effect to such proposed Revocation, and after giving pro forma effect to the incurrence of any such Indebtedness of such redesignated Subsidiary as if such Indebtedness was incurred on the date of the Revocation, the Company could incur $1.00 of additional Indebtedness (other than Permitted Debt) pursuant to Section 4.07 hereof.

All Designations and Revocations must be evidenced by a Board Resolution of the Board of Directors of the Company delivered to the Trustee certifying compliance with the foregoing provisions of this Section 4.17.

Section 4.18. Payments for Consent.

Neither the Company nor any of its Restricted Subsidiaries shall, directly or indirectly, pay or cause to be paid any consideration, whether by way of interest, fee or otherwise, to any Holder of Notes for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Notes unless such consideration is offered to be paid or is paid to all

Holders of Notes that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or agreement.

Section 4.19. Offer to Repurchase Upon a Change of Control.

(a) If a Change of Control occurs, each Holder of Notes shall have the right to require that the Company purchase all or any part (in amounts of $1,000 or whole multiples of $1,000 in excess thereof) of such Holder’s Notes pursuant to the offer described below (the “Change of Control Offer”). In the Change of Control Offer, the Company shall offer to purchase all of the Notes, at a purchase price (the “Change of Control Purchase Price”) in cash in an amount equal to 101% of the principal amount of such Notes, plus accrued and unpaid interest, if any, to the date of purchase (the “Change of Control Purchase Date”) (subject to the rights of holders of record on relevant record dates to receive interest due on an interest payment date).

(b) Within 30 days after any Change of Control or, at the Company’s option, prior to such Change of Control but after it is publicly announced, the Company must notify the Trustee and give written notice of the Change of Control (the “Change of Control Purchase Notice”) to each Holder of Notes, by first-class mail, postage prepaid, at his address appearing in the security register. The Change of Control Purchase Notice must state, among other things:

(1) that a Change of Control has occurred or will occur and the date of such event;

(2) the circumstances and relevant facts regarding such Change of Control, including information with respect to pro forma historical income, cash flow and capitalization after giving effect to such Change of Control;

(3) the Change of Control Purchase Price and the Change of Control Purchase Date, which shall be fixed by the Company on a Business Day no earlier than 30 days nor later than 60 days from the date the notice is mailed, or such later date as is necessary to comply with requirements under the Exchange Act; provided that the Change of Control Purchase Date may not occur prior to the Change of Control;

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

(5) that, unless the Company defaults in the payment of the Change of Control Purchase Price, any Notes accepted for payment pursuant to the Change of Control Offer shall cease to accrue interest after the Change of Control Purchase Date; and

(6) other procedures that a Holder of Notes must follow to accept a Change of Control Offer or to withdraw acceptance of the Change of Control Offer.

(c) Upon receipt by the Company of the proper tender of Notes, the Holder of the Note in respect of which such proper tender was made shall (unless the tender of such Note is properly withdrawn at least one Business Day prior to the Change of Control Purchase Date) thereafter be entitled to receive solely the Change of Control Purchase Price with respect to such Notes. Upon surrender of any such Note for purchase in accordance with the foregoing provisions, such Note shall be paid by the Company at the Change of Control Purchase Price; provided, however, that installments of interest whose Stated Maturity is on or prior to the Change of Control Purchase Date shall be payable to the Holders of such Notes, registered as such on the relevant Regular Record Dates according to the terms and the provisions of Section 2.03. If any Note tendered for purchase in accordance with the provisions of this Section 4.19 shall not be so paid upon surrender thereof, the principal thereof (and premium, if any, thereon) shall, until paid, bear interest from the Change of Control Purchase Date at the rate borne by such Note. Holders electing to have Notes purchased will be required to surrender such Notes to the Paying Agent at the address specified in the Change of Control Purchase Notice at least one Business Day prior to the Change of Control Purchase Date. Any Note that is to be purchased only in part shall be surrendered to a Paying Agent at the office of such Paying Agent (with, if the Company, the Registrar or the Trustee so require, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Registrar or the Trustee, as the case may be, duly executed by, the Holder thereof or such Holder’s attorney duly authorized in writing), and the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Note, without service charge, one or more new Notes of any authorized denomination as requested by such Holder in an aggregate principal amount equal to, and in exchange for, the portion of the principal amount of the Note so surrendered that is not purchased.

(d) The Company shall (i) not later than the Change of Control Purchase Date, accept for payment Notes or portions thereof tendered pursuant to the Change of Control Offer, (ii) not later than 1:00 p.m. (New York time) on the Business Day following the Change of Control Purchase Date, deposit with the Trustee or with a Paying Agent an amount of money in same day funds sufficient to pay the aggregate Change of Control Purchase Price of all the Notes or portions thereof which have been so accepted for payment and (iii) not later than 1:00 p.m. (New York time) on the Business Day following the Change of Control Purchase Date, deliver to the Paying Agent an Officers’ Certificate stating the Notes or portions thereof accepted for payment by the Company. The Paying Agent shall promptly mail or deliver to Holders of Notes so accepted payment in an amount equal to the Change of Control Purchase Price of the Notes purchased from each such Holder, and the Company shall execute and the Trustee shall promptly authenticate and mail or deliver to such Holders a new Note equal in principal

amount to any unpurchased portion of the Note surrendered. Any Notes not so accepted shall be promptly mailed or delivered by the Paying Agent at the Company’s expense to the Holder thereof. The Company will publicly announce the results of the Change of Control Offer on the Change of Control Purchase Date. For purposes of this Section 4.19, the Company shall choose a Paying Agent which shall not be the Company.

(e) A tender made in response to a Change of Control Purchase Notice may be withdrawn if the Company receives, not later than one Business Day prior to the Change of Control Purchase Date, a telegram, telex, facsimile transmission or letter, specifying, as applicable:

(1) the name of the Holder;

(2) the certificate number of the Note in respect of which such notice of withdrawal is being submitted;

(3) the principal amount of the Note (which shall be $1,000 or whole multiples of $1,000 in excess thereof) delivered for purchase by the Company as to which such notice of withdrawal is being submitted;

(4) a statement that such Holder is withdrawing his election to have such principal amount of such Note purchased; and

(5) the principal amount, if any, of such Note (which shall be $1,000 or whole multiples of $1,000 in excess thereof) that remains subject to the original Change of Control Purchase Notice and that has been or will be delivered for purchase by the Company.

(f) The Trustee and the Paying Agent shall return to the Company, upon its request, any cash that remains unclaimed for two years after a Change of Control Purchase Date together with interest or dividends, if any, thereon (subject to Section 7.01(f) hereof), held by them for the payment of the Change of Control Purchase Price; and the Holder of such tendered and accepted Note shall thereafter look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such cash, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, shall at the expense of the Company cause to be published once in The New York Times and The Wall Street Journal (national edition) or send to each Holder entitled to such money 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 Company; provided, further however, that (x) to the extent that the aggregate amount of cash deposited by the Company pursuant to clause (ii) of paragraph (d) of this Section 4.19 exceeds the aggregate Change of Control Purchase Price of the Notes or portions thereof to be purchased, then the Trustee

shall hold such excess for the Company and (y) unless otherwise directed by the Company in writing, promptly after the Business Day following the Change of Control Purchase Date the Trustee shall return any such excess to the Company together with interest, if any, thereon (subject to Section 7.01(f) hereof).

(g) The Company shall comply with the applicable tender offer rules, including Rule 14e-1 under the Exchange Act, and any other applicable securities laws or regulations in connection with a Change of Control Offer. To the extent that the provisions of any securities laws or regulations conflict with this Section 4.19, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 4.19 by virtue of such conflict.

(h) Notwithstanding the foregoing, the Company 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 in this Indenture applicable to a Change of Control Offer made by the Company and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer.

Section 4.20. Corporate Existence.

Subject to Article Five, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect the corporate existence of the Company and each Restricted Subsidiary; provided that the Company is not required to preserve any the existence of any Restricted Subsidiary, if the maintenance or preservation thereof is no longer desirable in the conduct of the business of the Company and its Restricted Subsidiaries taken as a whole.

ARTICLE FIVE
SUCCESSORS

Section 5.01. Consolidation, Merger and Sale of Assets.

(a) The Company will not, in a single transaction or through a series of related transactions, consolidate with or merge with or into any other Person or sell, assign, convey, transfer, lease or otherwise dispose of all or substantially all of its properties and assets to any Person or group of Persons, or permit any of its Restricted Subsidiaries to enter into any such transaction or series of transactions, if such transaction or series of transactions, in the aggregate, would result in a sale, assignment, conveyance, transfer, lease or disposition of all or substantially all of the properties and assets of the Company and its Restricted Subsidiaries on a Consolidated basis to any other Person or group of Persons (other than the Company or a Guarantor), unless at the time and after giving effect thereto:

(1) either (a) the Company will be the continuing corporation or (b) the Person (if other than the Company) formed by such consolidation or into which the Company is merged or the Person which acquires by sale, assignment, conveyance, transfer, lease or disposition all or substantially all of the properties and assets of the Company and its Restricted Subsidiaries on a Consolidated basis (the “Surviving Entity”) will be a corporation, limited liability company or limited partnership (provided that in the event the Surviving Entity is a limited partnership, then a Subsidiary of the Surviving Entity that is a corporation or limited liability company shall execute a supplemental indenture pursuant to which it shall become a co-obligor of the Surviving Entity’s obligations under the Notes and this Indenture) duly organized and validly existing under the laws of the United States of America, any state thereof or the District of Columbia and such Person expressly assumes, by a supplemental indenture, in a form reasonably satisfactory to the Trustee, all the obligations of the Company under the Notes and this Indenture, and the Notes and this Indenture will remain in full force and effect as so supplemented (and any Guarantees will be confirmed as applying to such Surviving Entity’s obligations);

(2) immediately after giving effect to such transaction on a pro forma basis (and treating any Indebtedness not previously an obligation of the Company or any of its Restricted Subsidiaries which becomes the obligation of the Company or any of its Restricted Subsidiaries as a result of such transaction as having been incurred at the time of such transaction), no Default or Event of Default will have occurred and be continuing;

(3) except in the case of a merger of the Company with or into a Restricted Subsidiary or a Restricted Subsidiary with or into the Company or any other Restricted Subsidiary, or a sale, assignment, conveyance, transfer, lease or disposition of properties or assets to the Company or one or more Restricted Subsidiaries, immediately after giving effect to such transaction on a pro forma basis (on the assumption that the transaction occurred on the first day of the four-quarter period for which financial statements are available ending immediately prior to the consummation of such transaction with the appropriate adjustments with respect to the transaction being included in such pro forma calculation), the Company (or the Surviving Entity if the Company is not the continuing obligor under this Indenture) could incur $1.00 of additional Indebtedness (other than Permitted Debt) under Section 4.07 hereof;

Section 6.02. Acceleration.

(a) If an Event of Default (other than as specified in clause (8) or clause (9) of Section 6.01 with respect to the Company) shall occur and be continuing with respect to this Indenture, the Trustee or the Holders of not less than 25% in aggregate principal amount of the Notes then outstanding may, and the Trustee at the request of such Holders shall, declare all unpaid principal of, premium, if any, and accrued interest on all Notes to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by the Holders of the Notes) and upon any such declaration, such principal, premium, if any, and interest shall become due and payable immediately. If an

Event of Default specified in clause (8) or clause (9) of Section 6.01 occurs and is continuing with respect to the Company, then all the Notes shall ipso facto become due and payable immediately in an amount equal to the principal amount of the Notes, together with accrued and unpaid interest, if any, to the date the Notes become due and payable, without any declaration or other act on the part of the Trustee or any Holder of Notes. Thereupon, the Trustee may, at its discretion, proceed to protect and enforce the rights of the Holders of Notes by appropriate judicial proceedings.

(b) After a declaration of acceleration, but before a judgment or decree for payment of the money due has been obtained by the Trustee, the Holders of a majority in aggregate principal amount of Notes outstanding by written notice to the Company and the Trustee, on behalf of the Holders of Notes, may rescind and annul such declaration and its consequences if:

(1) the Company has paid or deposited with the Trustee a sum sufficient to pay (A) all sums paid or advanced by the Trustee under this Indenture and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, (B) all overdue interest on all Notes then outstanding, (C) the principal of, and premium, if any, on any Notes then outstanding which have become due otherwise than by such declaration of acceleration and interest thereon at the rate borne by the Notes and (D) to the extent that payment of such interest is lawful, interest upon overdue interest at the rate borne by the Notes;

(2) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction; and

(3) all Events of Default, other than the non-payment of principal of, premium, if any, and interest on the Notes which have become due solely by such declaration of acceleration, have been cured or waived as provided in this Indenture.

No such rescission shall affect any subsequent default or impair any right consequent thereon.

Section 6.03. Other Remedies.

(a) 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, or interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture.

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

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

Section 6.04. Waiver of Past Defaults.

The Holders of not less than a majority in aggregate principal amount of the Notes outstanding, by written notice to the Trustee and the Company, may on behalf of the Holders of all outstanding Notes waive any existing Default or Event of Default under this Indenture and its consequences, except a continuing Default or Event of Default (1) in the payment of the principal of, premium, if any, or interest on any Note (which may only be waived with the consent of each Holder of Notes affected) or (2) in respect of a covenant or provision which under this Indenture cannot be modified or amended without the consent of the Holder of each Note affected by such modification or amendment. The Company shall deliver to the Trustee an Officers’ Certificate stating that the requisite percentage of Holders have consented to such waiver and attaching copies of such consents. In case of any such waiver, the Company, the Trustee and the Holders shall be restored to their former positions and rights hereunder and under the Notes, respectively. This Section 6.04 shall be in lieu of Section 316(a)(1)(B) of the TIA and such Section 316(a)(1)(B) of the TIA is hereby expressly excluded from this Indenture and the Notes, as permitted by the TIA. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.

Section 6.05. Control by Majority.

Holders of a majority in principal amount of the then outstanding Notes may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or that the Trustee determines may be unduly prejudicial to the rights of other Holders of Notes or that may involve the Trustee in personal liability. The Trustee may withhold from Holders of the Notes notice of any continuing Default or Event of Default (except a Default or Event of Default relating to the payment of principal or interest) if it determines that withholding notice is in their interest.

Section 6.06. Limitation on Suits.

(a) No holder of any of the Notes of any series has any right to institute any proceedings with respect to this Indenture or any remedy thereunder, unless (1) such holder has previously given the Trustee written notice that an Event of Default has occurred and is continuing, (2) the holders of at least 25% in aggregate principal amount of the outstanding Notes of such series have made written request to the Trustee to institute a proceeding or pursue a remedy,

100

(3) such holders have offered reasonable security or indemnity to the Trustee to institute such proceeding or pursue such remedy as Trustee under the Notes of such series and the Indenture, (4) the Trustee has failed to institute such proceeding or pursue such remedy within 30 days after receipt of such notice and such offer of security or indemnity, and (5) the Trustee, within such 30-day period, has not received directions inconsistent with such written request by holders of a majority in aggregate principal amount of the outstanding Notes of such series.

(b) The limitations set forth in paragraph (a) of this Section 6.06 do not, however, apply to a suit instituted by a holder of a Note for the enforcement of the payment of the principal of, premium, if any, or interest on such Note on or after the respective due dates expressed in such Note.

Section 6.07. Rights of Holders of Notes to Receive Payment.

Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal, premium, if any, or interest on such Note, on or after the respective due dates expressed in such 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 6.08. Collection Suit by Trustee.

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

Section 6.09. Trustee May File Proofs of Claim.

The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the Company or any Guarantor (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 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,

101

disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 6.10. Priorities.

(a) If the Trustee collects any money or other property pursuant to this Article Six, it shall pay out the money and other property in the following order:

First: to the Trustee, its agents and attorneys for amounts due under Section 7.07 hereof, including payment of all compensation, 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, 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

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

(b) The Trustee may fix a record date and payment date for any payment to Holders of Notes 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 and expenses, 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 does not apply to a suit by the Trustee, a suit by a Holder of a Note pursuant to Section 6.07 hereof, or a

102

suit by Holders of more than ten percent in principal amount of the then outstanding Notes.

If a Default or Event of Default occurs and is continuing and if it is known to the Trustee, the Trustee shall mail to Holders of Notes a notice of the Default or Event of Default within 90 days after the Trustee gains knowledge of the Default or Event of Default unless such Default or Event of Default shall have been cured or waived before the giving of such notice. Except in the case of a Default or Event of Default in payment of principal of, premium or interest on any Note, the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders of the Notes.

(a) Within 60 days after each May 15 beginning with the May 15 following the date hereof, and for so long as Notes remain outstanding, the Trustee shall mail to the Holders of the Notes a brief report dated as of such reporting date that complies with TIA Section 313(a) (but if no event described in TIA Section 313(a) has occurred within the twelve months preceding the reporting date, no report need be transmitted).

(a) The Company shall pay to the Trustee (in its capacity as Trustee, and, to the extent it has been appointed as such, as Paying Agent and Registrar) from time to time reasonable compensation for its acceptance of this Indenture and services hereunder in accordance with a written schedule provided by the Trustee to the Company. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee promptly upon request for all reasonable and customary disbursements, advances and reasonable out-of-pocket expenses incurred or made by it in addition to the compensation for its services, except those resulting from its own negligent action, negligent failure to act or willful misconduct. Such expenses shall include the reasonable and customary compensation, disbursements and expenses of the Trustee’s agents and counsel.

(b) The Company shall indemnify the Trustee in its capacity against any and all losses, liabilities or reasonable out-of-pocket expenses 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 Company (including this Section 7.07) and defending itself against

106

any claim (whether asserted by either of the Company 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, liability or expense may be attributable to its negligence or bad faith. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder. The Company shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may elect to have separate counsel defend the claim, but the Company will be obligated to pay the reasonable fees and expenses of such separate counsel only if the Company fails to assume the Trustee’s defense or there is a conflict of interest between the Company, on the one hand, and the Trustee, on the other hand, with respect to the claim, as reasonably determined by the Trustee. The Company need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld.

(c) The obligations of the Company under this Section 7.07 shall survive the satisfaction and discharge of this Indenture.

(d) To secure the Company’s payment obligations in this section, 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 and interest on particular Notes. Such Lien shall survive the satisfaction and discharge of this Indenture.

(e) When the Trustee incurs expenses or renders services after an Event of Default specified in clause (8) of Section 6.01 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.

Section 7.08. Replacement of Trustee.

(a) 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 7.08.

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

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

(ii) 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;

107

(iii) a custodian or public officer takes charge of the Trustee or its property; or

(iv) the Trustee becomes incapable of acting.

(c) If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Company.

(d) If a successor Trustee does not take office within 30 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company, or the Holders of Notes of at least 10% in principal amount of the then outstanding Notes may petition at the expense of the Company any court of competent jurisdiction for the appointment of a successor Trustee.

(e) If the Trustee, after written request by any Holder who has been a Holder for at least three months, fails to comply with Section 7.10, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

(f) A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon, 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 successor Trustee shall mail a notice of its succession to Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, provided all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 7.07 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Company’s obligations under Section 7.07 hereof shall continue for the benefit of the retiring Trustee.

Section 7.09. Successor Trustee by Merger, Etc.

The Company may, at its option and at any time, elect to have either Section 8.02 or 8.03 hereof be applied to all outstanding Notes upon compliance with the conditions set forth below in this Article Eight.

Section 8.02. Legal Defeasance and Discharge.

Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Company shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have been discharged from its obligations with respect to this Indenture all outstanding Notes and all obligations of the Guarantors shall be deemed to have been discharged with respect to their obligations under this Indenture and the Guarantees on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Company and the Guarantors shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes and Guarantees, respectively, which shall thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 hereof and the other Sections of this Indenture referred to in clauses (a) and (b) of this Section 8.02, and shall be deemed discharged from the payment and performance of all other obligations under this Indenture, the Notes and the Guarantees (and the Trustee, on demand of and at the expense of the Company, 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 solely from Funds in Trust (as defined in Section 8.04 hereof and as more fully set forth in such Section) payments in respect of the principal of, premium, if any, and interest on such Notes when such payments are due, (b) subject to clause (a) of this Section 8.02, the Company’s obligations with respect to such Notes under Article Two and Section 4.02 hereof,

Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Company shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from its obligations, and each Restricted Subsidiary shall be released from its obligations, under the covenants contained in Sections 4.03, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.14, 4.15, 4.16, 4.17, 4.19, and 5.01 hereof with respect to the outstanding Notes on and after the date the conditions set forth in Section 8.04 are satisfied (hereinafter, “Covenant Defeasance”), and the Notes shall thereafter be deemed not “outstanding” for the purposes of any direction, 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 Company and each Restricted Subsidiary 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 6.01 hereof, but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby. In addition, upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, Sections 6.01(3) through (7) shall not constitute Events of Default.

(e) such deposit shall not result in a breach, or constitute a default under, any material agreement or instrument (other than this Indenture) to which the Company, any Guarantor or any Restricted Subsidiary is a party or by which it is bound or if such breach or default would occur, which is not waived as of, or for all purposes, on or after, the date of such deposit;

(f) such deposit shall not result in the trust arising from such deposit constituting an investment company within the meaning of the Investment Company Act of 1940, as amended, unless such trust shall be registered under such Act or exempt from registration thereunder;

111

or any Guarantor under any applicable bankruptcy or insolvency law and assuming no intervening bankruptcy or insolvency of the Company or any Guarantor between the date of deposit and the 91st day following the deposit) after the 91st day following the deposit, the trust funds will not be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors’ rights generally;

112

amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

Section 8.06. Repayment to the Company.

Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, premium, if any, or interest on any Note and remaining unclaimed for two years after such principal, and premium, if any, or interest has become due and payable shall be paid to the Company upon its request or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, shall at the expense of the Company 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 Company.

Section 8.07. 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 8.02 or 8.03 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 Company’s obligations to make the related payments under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.02 or 8.03 hereof, as the case may be; provided, however, that, if the Company make any payment of principal of, premium, if any, or interest on any Note following the reinstatement of its obligations, the Company 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.

Section 9.02. With Consent of Holders of Notes.

(a) Except as provided below in this Section 9.02, the Company, any Guarantor, any other obligor under the Notes and the Trustee may amend or supplement this Indenture or the Notes with the consent of the Holders of at least a majority in aggregate principal amount of the Notes (including Additional Notes, if any) then outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes); provided, however, that no such modification or amendment may, without the consent of the Holder of each outstanding Note affected thereby:

However, any such Holder of a Note or subsequent Holder of a Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the amendment, supplement or waiver becomes effective.

ARTICLE TEN
GUARANTEES

Section 10.01. Guarantee.

(a) Subject to this Article Ten, each of the Guarantors hereby, jointly and severally, fully and unconditionally, guarantees, on a senior unsecured basis, to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or the obligations of the Company hereunder or thereunder, that: (i) the principal of, premium, if any, and interest on the Notes will be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful (subject in all cases to any applicable grace period provided herein), and all other monetary obligations of the Company to the Holders or the Trustee hereunder or thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and (ii) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, that same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at stated maturity, by acceleration or otherwise. Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors shall be jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection.

(b) The Guarantors hereby agree that, to the maximum extent permitted under applicable law, their obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same or

118

any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a Guarantor. Subject to Section 6.06 hereof, each Guarantor hereby waives diligence, presentment, demand of 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, protest, notice and all demands whatsoever and covenant that this Guarantee shall not be discharged except by complete performance of the obligations contained in the Notes and this Indenture.

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

(d) Each Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article Six hereof for the purposes of this Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any declaration of acceleration of such obligations as provided in Article Six hereof, such obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantors for the purpose of this Guarantee. Each Guarantor that makes a payment or distribution under its Guarantee shall have the right to seek contribution from any non-paying Guarantor, in a pro rata amount based on the net assets of each Guarantor determined in accordance with GAAP, so long as the exercise of such right does not impair the rights of the Holders under the Guarantee.

(e) In respect to its obligations under its Guarantee, each Guarantor agrees to be bound to, and hereby covenants, with respect to itself, the covenant set forth in Section 4.06 hereof.

(f) The Obligations of each Guarantor under its Guarantee pursuant to this Article Ten shall rank equally in right of payment with other existing and future senior Indebtedness of such Guarantor, and senior in right of payment to all existing and future Subordinated Indebtedness of such Guarantor.

Section 10.02. Limitation on Guarantor Liability.

Each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform

119

Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of such Guarantor will be limited to the maximum amount which, after giving effect to all other contingent and fixed liabilities of such Guarantor, and after giving effect to any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under its Guarantee or pursuant to its contribution obligations under this Article Ten, will result in the obligations of such Guarantor under its Guarantee not constituting a fraudulent conveyance or fraudulent transfer under federal or state law. Until such time as the Notes are paid in full, each Guarantor hereby waives all rights of subrogation or contribution, whether arising by contract or operation of law (including, without limitation, any such right arising under federal Bankruptcy Law) or otherwise by reason of any payment by it pursuant to the provisions of this Article Ten. Each Guarantor that makes a payment or distribution under its Guarantee will be entitled to a contribution from each other Guarantor in a pro rata amount based on the net assets of each Guarantor determined in accordance with GAAP.

Section 10.03. Execution and Delivery of Guarantee.

(a) To evidence its Guarantee set forth in Section 10.01, on the Issue Date each Initial Guarantor shall be required to have a notation of such Guarantee substantially in the form included in Exhibit E hereto endorsed by an Officer of such Initial Guarantor by manual or facsimile signature on each Note authenticated and delivered by the Trustee.

(b) Each Guarantor hereby agrees that its Guarantee set forth in Section 10.01 shall remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Guarantee.

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

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

(e) Subsequent to the date of this Indenture, in the event a Restricted Subsidiary is required by Section 4.12 hereof to guarantee the Company’s obligations under the Notes and this Indenture, the Company shall cause such Restricted Subsidiary to execute a supplemental indenture to this Indenture substantially in the form included in Exhibit E hereto and Guarantees in accordance with Section 4.12 hereof and this Article Ten, to the extent applicable.

120

Section 10.04. Releases of Guarantors.

(a) A Guarantor will be deemed automatically and unconditionally released and discharged from all of its obligations under its Guarantee without any further action on the part of the Trustee or any Holder of the Notes:

(1) in connection with any sale or other disposition of all or substantially all of the assets of such Guarantor (including by way of merger or consolidation) to one or more Persons that are not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary, if such sale or other disposition complies with Sections 4.09 and 4.11 hereof;

(2) in connection with any sale of all of the Capital Stock of a Guarantor to one or more Persons that are not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary, if such sale complies with Sections 4.09 and 4.11 hereof;

(3) if the Company properly designates such Guarantor as a Non-Guarantor Restricted Subsidiary and such Restricted Subsidiary is not required to issue a Guarantee of the Notes pursuant to Section 4.12 hereof;

(4) if the Company properly designates any Restricted Subsidiary that is a Guarantor as an Unrestricted Subsidiary;

(5) if a Guarantor under any Credit Facility is released from its Guarantee pursuant to the terms of all Credit Facilities;

(6) if the Notes are discharged in accordance with the procedures set forth in Article Eight or Article Eleven hereof; or

(7) upon the liquidation or dissolution of such Guarantor.

provided that any such release and discharge pursuant to clauses (1), (2), (4), (5) and (6) above shall occur only to the extent that all obligations of such Guarantor under all of its guarantees of, and under all of its pledges of assets or other security interests which secure any, Indebtedness of the Company shall also terminate at such time.

(b) Any Guarantor not released from its obligations under its 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 Ten.

121

Section 12.10. Trust Indenture Act Controls.

If and to the extent that any provision of this Indenture limits, qualifies or conflicts with the duties imposed by TIA Section 318(c), the imposed duties shall control.

Section 12.11. Successors.

All agreements of the Company in this Indenture and the Notes shall bind their successors. All agreements of the Trustee in this Indenture shall bind its successors. All agreements of each Guarantor in this Indenture shall bind its successors, except as otherwise provided in Section 5.01 or 10.04.

Section 12.12. Severability.

In case any provision in this Indenture or the Notes 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 12.13. Counterpart Originals.

The parties may sign any number of copies of this Indenture. Each signed copy shall be an original, but all of them together represent the same agreement.

Section 12.14. Acts of Holders.

(a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by the Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by agents duly appointed in writing, and may be given or obtained in connection with a purchase of, or tender offer or exchange offer for, outstanding Notes; and, except as herein otherwise expressly provided, such action shall become effective when such

127

instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to the Company. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and conclusive in favor of the Trustee and the Company if made in the manner provided in this Section 12.14.

(b) The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to such witness, notary or officer the execution thereof. Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of authority. The fact and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other manner which the Trustee deems sufficient.

(c) Notwithstanding anything to the contrary contained in this Section 12.14, the principal amount and serial numbers of Notes held by any Holder, and the date of holding the same, shall be proved by the register of the Notes maintained by the Registrar as provided in Section 2.04 hereof.

Notwithstanding TIA Section 316(c), such record date shall be the record date specified in or pursuant to such Board Resolution, which shall be a date not earlier than the date 30 days prior to the first solicitation of Holders generally in connection therewith or the date of the most recent list of Holders forwarded to the Trustee prior to such solicitation pursuant to Section 2.06 hereof and not later than the date such solicitation is completed. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act may be given before or after such record date, but only the Holders of record at the close of business on such record date shall be deemed to be Holders for the purposes of determining whether Holders of the requisite proportion of the then outstanding Notes have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the then outstanding Notes shall be computed as of such record date; provided that no such authorization, agreement or consent by the Holders on such record date shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than eleven months after the record date.

128

(e) Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Note shall bind every future Holder of the same Note and the Holder of every Note issued upon the registration or transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Company in reliance thereon, whether or not notation of such action is made upon such Note.

(f) Without limiting the foregoing, a Holder entitled hereunder to take any action hereunder with regard to any particular Note may do so itself with regard to all or any part of the principal amount of such Note or by one or more duly appointed agents each of which may do so pursuant to such appointment with regard to all or any part of such principal amount.

(g) For purposes of this Indenture, any action by the Holders which may be taken in writing may be taken by electronic means or as otherwise reasonably acceptable to the Trustee.

Section 12.15. Benefit of Indenture.

Nothing in this Indenture or in the Notes, express or implied, shall give to any Person, other than the parties hereto, any Paying Agent, any Registrar and its successors hereunder, and the Holders, any benefit or any legal or equitable right, remedy or claim under this Indenture.

Section 12.16. Table of Contents, Headings, Etc.
