The Notes may have notations, legends or endorsements required by law, stock exchange rule or usage. The Company shall furnish any such notations, legends or endorsements to the Trustee in writing. Each Note shall be dated the date of its authentication. The Notes shall be in denominations of $2,000 and integral multiples of $1,000 in excess of $2,000.

The terms and provisions contained in the Notes shall constitute, and are hereby expressly made, a part of this Indenture and the Company, the Guarantors, the Trustee and the Collateral Agent, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any provision of any Note conflicts with the express provisions of this Indenture, the provisions of this Indenture shall govern and be controlling.

(b) Notes issued in global form shall be substantially in the form of Exhibit A attached hereto (including the Global Note Legend thereon). Notes issued in definitive form shall be substantially in the form of Exhibit A attached hereto (but without the Global Note Legend thereon). Each Global Note shall represent such of the outstanding Notes as will be specified therein and each shall provide that it represents the aggregate principal amount of outstanding Notes from time to time as reflected in the records of the Trustee and that the aggregate principal amount of outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate, on the “Schedule of Exchanges of Interests in the Global Note” attached to such Global Note to reflect exchanges and redemptions.

(c) Notes offered and sold in reliance on Rule 144A shall be issued in the form of a 144A Global Note, which shall be deposited on behalf of the purchasers of the Notes represented thereby with the Custodian and registered in the name of the Depositary or a nominee of the Depositary, duly executed by the Company and authenticated by the Trustee as hereinafter provided.

(d) Notes offered and sold in reliance on Regulation S shall be issued in the form of a Regulation S Global Note, which shall be deposited on behalf of the purchasers of the Notes represented thereby with the Custodian and registered in the name of the Depositary or a nominee of the Depositary for the accounts of designated agents holding on behalf of Euroclear or Clearstream, duly executed by the Company and authenticated by the Trustee as hereinafter provided.

(e) The aggregate principal amount of Notes that may be authenticated and delivered under this Indenture is unlimited, subject to compliance with Section 2.07 hereof and Section 4.09 hereof.

Section 2.02. Execution and Authentication.

An Officer must sign the Notes for the Company by manual or facsimile signature.

If an Officer whose signature is on a Note no longer holds that office at the time a Note is authenticated, the Note will nevertheless be valid.

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

The Trustee shall, upon receipt of a written order of the Company signed by an Officer (an “Authentication Order”), authenticate Notes for original issue under this Indenture, including any Additional Notes issued pursuant to Section 2.07 hereof. The aggregate principal amount of Notes outstanding at any time may not exceed the aggregate principal amount of Notes authorized for issuance by the Company pursuant to one or more Authentication Orders, except as provided in Section 2.08 hereof.

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

Section 2.03. Registrar and Paying Agent.

The Company will maintain an office or agency where Notes may be presented for registration of transfer or for exchange (“Registrar”) and an office or agency where Notes may be presented for payment (“Paying Agent”). The Registrar will keep a register of the Notes and of their transfer and exchange. The Company may appoint one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any additional paying agent. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company will notify the Trustee in writing of the name and address of any Agent not a party to this Indenture. If the Company fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Company or any of its Subsidiaries may act as Paying Agent or Registrar.

The Company initially appoints The Depository Trust Company (“DTC”) to act as Depositary with respect to the Global Notes. The Company has entered into a blanket letter of representations with DTC in the form provided by DTC and the Trustee and each Agent are hereby authorized to act in accordance with such letter and Applicable Procedures.

The Company initially appoints the Trustee to act as the Registrar and Paying Agent and to act as Custodian with respect to the Global Notes.

The Company shall be responsible for making calculations called for under the Notes, including but not limited to determination of redemption price, premium, if any, and any additional amounts or other amounts payable on the Notes. The Company will make the calculations in good faith and, absent manifest error, its calculations will be final and binding on the Holders. The Company will provide a schedule of its calculations to the Trustee when requested by the Trustee, and the Trustee is entitled to rely conclusively on the accuracy of the Company’s calculations without independent verification.

Section 2.04. Paying Agent to Hold Money in Trust.

The Company will require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal, premium, if any, or interest on the Notes, and will notify the Trustee of any default by the Company in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than CF Holdings or a Subsidiary) will have no further liability for the money. If CF Holdings or a Subsidiary acts as Paying Agent, it will segregate and hold in a separate trust fund for the benefit of the Holders all money held by it as Paying Agent. Upon any bankruptcy or reorganization proceedings relating to the Company, the Trustee will serve as Paying Agent for the Notes.

Section 2.05. Holder Lists.

The Trustee will preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of all Holders and shall otherwise comply with TIA § 312(a). If the Trustee is not the Registrar, the Company will furnish to the Trustee at least seven Business Days before each Interest Payment Date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of the Holders and the Company shall otherwise comply with TIA § 312(a).

Section 2.06. Transfer and Exchange.

(a) Transfer and Exchange of Global Notes. A Global Note may not be transferred as a whole except by the Depositary to a nominee of the Depositary, by a nominee of the Depositary to the Depositary or to another nominee of the Depositary, or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. All Global Notes shall be exchanged by the Company for Definitive Notes if:

(1) the Company delivers to the Trustee notice from the Depositary that it is unwilling or unable to continue to act as Depositary or that it is no longer a clearing agency registered under the Exchange Act and, in either case, a successor Depositary is not appointed by the Company within 90 days after the date of such notice from the Depositary;

(2) the Company in its sole discretion determines that the Global Notes (in whole but not in part) should be exchanged for Definitive Notes and delivers a written notice to such effect to the Trustee (provided that Regulation S Global Notes may not be exchanged for Definitive Notes pursuant to this clause (2) prior to the expiration of the applicable Restricted Period and the receipt of any certificates required under the provisions of Regulation S); or

(3) there has occurred and is continuing an Event of Default with respect to the Notes and DTC requests the issuance of Definitive Notes.

Upon the occurrence of any of the preceding events in (1), (2) or (3) above, Definitive Notes shall be issued in such names and in any approved denominations as the Depositary shall instruct the Trustee. Global Notes also may be exchanged or replaced, in whole or in part, as provided in Sections 2.08 and 2.11 hereof. Every Note authenticated and delivered in exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to this Section 2.06 or Sections 2.08 or 2.11 hereof, shall be authenticated and delivered in the form of, and shall be, a Global Note, except for Definitive Notes issued subsequent to any of the events described in clauses (1), (2) or (3) above and pursuant to clause (c) below. A Global Note may not be exchanged for another Note other than as provided in this Section 2.06(a); however, beneficial interests in a Global Note may be transferred and exchanged as provided in Section 2.06(b), (c) and (d) hereof.

None of the Company, any of the Guarantors or the Trustee will be liable for any delay by DTC, its nominee or any direct or indirect DTC participant in identifying the Beneficial Owners of the Notes. The Company, the Guarantors and the Trustee may conclusively rely on, and will be protected in relying on, instructions from DTC or its nominee for all purposes, including with respect to the registration and delivery, and the respective principal amounts, of the certificated Notes to be issued.

(b) Transfer and Exchange of Beneficial Interests in the Global Notes. The transfer and exchange of beneficial interests in the Global Notes shall be effected through the Depositary, in accordance with the provisions of this Indenture and the Applicable Procedures.

Beneficial interests in any Unrestricted Global Note may be transferred to Persons who take delivery thereof in the form of a beneficial interest in an Unrestricted Global Note. No written orders or instructions shall be required to be delivered to the Registrar to effect the transfers described in this Section 2.06(b)(1).

(2) All Other Transfers and Exchanges of Beneficial Interests in Global Notes. In connection with all transfers and exchanges of beneficial interests that are not subject to Section 2.06(b)(1) hereof, the transferor of such beneficial interest must deliver to the Registrar the applicable certificates prescribed by the succeeding sections and subparagraphs and either:

(A) (1) a written order from a Participant or an Indirect Participant given to the Depositary in accordance with the Applicable Procedures directing the Depositary to credit or cause to be credited a beneficial interest in another Global Note in an amount equal to the beneficial interest to be transferred or exchanged, and (2) instructions given in accordance with the Applicable Procedures containing information regarding the Participant account to be credited with such increase; or

(3) Transfer of Beneficial Interests to Another Restricted Global Note. A beneficial interest in any Restricted Global Note may be transferred to a Person who takes delivery thereof in the form of a beneficial interest in another Restricted Global Note if the transfer complies with the requirements of Section 2.06(b)(2) hereof and the transferor delivers to the Registrar the following:

(A) if the transferee will take delivery in the form of a beneficial interest in a 144A Global Note, a certificate in the form of Exhibit B hereto, including the certifications in item (1) thereof; or

A beneficial interest in any Restricted Global Note may be exchanged by any holder thereof for a beneficial interest in an Unrestricted Global Note or transferred to a Person who takes delivery thereof in the form of a beneficial interest in an Unrestricted Global Note if the exchange or transfer complies with the requirements of Section 2.06(b)(2) hereof and:

(A) such Notes are sold or exchanged pursuant to an effective registration statement under the Securities Act; or

(B) the Registrar receives the following:

and, in each such case set forth in this subparagraph (B), if the Company so requests or if the Applicable Procedures so require, such holder delivers to the Company an Opinion of Counsel in form reasonably acceptable to the Company to the effect that such exchange or transfer is in compliance with the Securities Act and that the restrictions on transfer contained herein and in the Private Placement Legend are no longer required in order to maintain compliance with the Securities Act.

If any such transfer or exchange is to be effected pursuant to subparagraph (A) or (B) above at a time when an Unrestricted Global Note has not yet been issued, the Company shall issue and, upon receipt of an Authentication Order in accordance with Section 2.02 hereof, the Trustee shall authenticate one or more Unrestricted Global Notes in an aggregate principal amount equal to the aggregate principal amount of beneficial interests transferred or exchanged pursuant to subparagraph (A) or (B) above.

Beneficial interests in an Unrestricted Global Note cannot be exchanged for, or transferred to Persons who take delivery thereof in the form of, a beneficial interest in a Restricted Global Note.

Upon the Company’s satisfaction that the Private Placement Legend shall no longer be required in order to maintain compliance with the Securities Act with respect to a particular Restricted Global Note, the Company may, but shall not be obligated to, cause the beneficial interests in such Restricted Global Note to be automatically exchanged into beneficial interests in one or more Unrestricted Global Notes, in accordance with this Section 2.06(b)(5), without any action required by or on behalf of the Holder (the “Automatic Exchange”) at any time on or after the date that is the 366th calendar day after (A) with respect to the Notes issued on the Issue Date, the Issue Date or (B) with respect to Additional Notes, if any, the issue date of such Additional Notes, or, in each case, if such day is not a Business Day, on the next succeeding Business Day (the “Automatic Exchange Date”).

Notwithstanding anything to the contrary in this Section 2.06, during the period between the Automatic Exchange Notice Date and the Automatic Exchange Date, no transfers or exchanges other than pursuant to this Section

2.06(b)(5) shall be permitted without the prior written consent of the Company. As a condition to any Automatic Exchange, the Company shall provide, and the Trustee shall be entitled to rely upon, an Officers’ Certificate reasonably acceptable to the Trustee to the effect that the Automatic Exchange shall be effected in compliance with the Securities Act and that the restrictions on transfer contained herein and in the Private Placement Legend shall no longer be required in order to maintain compliance with the Securities Act with respect to the Restricted Global Note to which such Automatic Exchange relates, and that the aggregate principal amount of the particular Restricted Global Note may be transferred to the particular Unrestricted Global Note by adjustment made on the records of the Trustee to reflect the Automatic Exchange. Upon such exchange of beneficial interests pursuant to this Section 2.06(b)(5), the aggregate principal amount of the Global Notes shall be increased or decreased by adjustments made on the records of the Trustee, to reflect the relevant increase or decrease in the principal amount of such Global Note resulting from the applicable exchange.

Section 2.07. Issuance of Additional Notes.

The Company shall be entitled, upon delivery of an Officers’ Certificate, Opinion of Counsel and Authentication Order, to issue Additional Notes under this Indenture which shall have identical terms as the Initial Notes issued on the Issue Date, other than with respect to the date of issuance and issue price and, if applicable, the initial interest accrual date and the initial interest payment date, subject to compliance with Section 4.09. The Initial Notes and any Additional Notes issued shall be treated as a single class for all purposes under this Indenture, provided that if the Additional Notes are not fungible with the Initial Notes for U.S. federal income tax purposes, the Additional Notes will have a separate CUSIP number.

If any mutilated Note is surrendered to the Trustee or the Company and the Trustee receives evidence to its satisfaction of the destruction, loss or theft of any Note, the Company will issue and the Trustee, upon receipt of an Authentication Order, will authenticate a replacement Note if the Trustee’s requirements are met. If required by the Trustee or the Company, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of (i) the Trustee to protect the Trustee and (ii) 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 its expenses in replacing a Note.

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

Section 2.09. Outstanding Notes.

The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section 2.09 as not outstanding. 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; however, Notes held by the Company or a Subsidiary of the Company shall not be deemed to be outstanding for purposes of Section 3.07 hereof.

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.

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

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

Section 2.10. 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 any Guarantor, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or any Guarantor, will be considered as though not outstanding, except that for the purposes of determining whether the Trustee will be protected in relying on any such direction, waiver or consent, only Notes that a Responsible Officer of the Trustee knows are so owned will be so disregarded.

Section 2.11. Temporary Notes.

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

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

Section 2.12. Cancellation.

The Company or one of its Affiliates at any time may deliver to the Trustee for cancellation any Notes previously authenticated and delivered hereunder which the Company or one of its Affiliates may have acquired in any manner whatsoever, and may deliver to the Trustee for cancellation any Notes previously authenticated hereunder which the Company has not issued and sold. The Registrar, any transfer agent and the Paying Agent shall forward to the Trustee any Notes surrendered to them for transfer, exchange or payment. The Trustee shall promptly cancel and dispose of in accordance with its customary procedures all Notes surrendered for transfer, exchange, payment or cancellation and upon written request shall deliver a certificate of disposition to the Company. The Company may not issue new Notes to replace Notes it has paid in full or delivered to the Trustee for cancellation.

Section 2.13. Defaulted Interest.

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

the special record date, the Company (or, upon the written request of the Company, the Trustee in the name and at the expense of the Company) will mail or cause to be mailed to Holders a Notice that states the special record date, the related payment date and the amount of such interest to be paid.

Section 2.14. CUSIP Numbers.

The Company in issuing the Notes may use CUSIP, ISIN or other similar numbers, if then generally in use, and thereafter with respect to such series, the Trustee may use such numbers in any notice (including any notice of redemption or exchange) 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 (including any notice of redemption or exchange) and that reliance may be placed only on the other identification numbers printed on the Notes, and any such notice or notice of redemption shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee in writing of any change in the CUSIP, ISIN or other similar numbers.

The Trustee shall promptly notify the Company in writing of the Notes selected for redemption or purchase and, in the case of any Note selected for partial redemption or purchase, the principal amount

thereof to be redeemed or purchased. Notes and portions of Notes selected shall be in minimum amounts of $2,000 or integral multiples of $1,000 in excess thereof; no Notes of $2,000 or less can be redeemed in part, except that if all of the Notes of a Holder are to be redeemed or purchased, the entire outstanding amount of Notes held by such Holder, even if not equal to $2,000 or an integral multiple of $1,000 in excess thereof, shall be redeemed or purchased. Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption or purchase also apply to portions of Notes called for redemption or purchase.

Section 3.03. Notice of Redemption.

At least 30 days but not more than 60 days before a redemption date, the Company shall mail or cause to be mailed by first class mail (or with respect to Global Notes, to the extent permitted or required by applicable DTC procedures or regulations, send electronically or cause to be sent electronically) a notice of redemption to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be mailed or sent more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of this Indenture pursuant to Articles 8 or 12 hereof.

(1) the redemption date;

(2) the redemption price, or manner of calculation thereof if not then known;

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

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

At the Company’s request, the Trustee will give the notice of redemption in the Company’s name and at its expense; provided, however, that the Company has delivered to the Trustee, at least 45 days prior to the redemption date (unless a shorter time is agreed to by the Trustee), an Officers’ Certificate requesting that the Trustee give such notice together with the notice to be given setting forth the information to be stated in such notice as provided in the preceding paragraph.

Section 3.04. Effect of Notice of Redemption.

Once notice of redemption is mailed or sent 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.

Not later than 10:00 a.m. (Eastern Time) on the redemption or purchase date, the Company shall deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption or purchase price of and accrued interest on all Notes to be redeemed or purchased 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 or purchase price of, and accrued interest on, all Notes to be redeemed or purchased.

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

Section 3.06. Notes Redeemed or Purchased in Part.

Upon surrender of a Note that is redeemed or purchased in part, the Company will issue and, upon receipt of an Authentication Order, the Trustee will authenticate for the Holder (or transfer by book entry) at the expense of the Company a new Note equal in principal amount to the unredeemed or unpurchased portion of the Note surrendered.

Section 3.07. Optional Redemption.

The Company may redeem the Notes, in whole at any time or in part from time to time, at its option, at a redemption price equal to the greater of:

(1)100% of the principal amount of the Notes to be redeemed; and

plus, in each case, accrued and unpaid interest, if any, thereon to, but not including, the applicable redemption date.

Notwithstanding the foregoing, installments of interest on Notes that are due and payable on Interest Payment Dates falling on or prior to a redemption date will be payable on the Interest Payment Date to the Holders as of the close of business on the relevant Record Date.

The Company will maintain an office or agency (which may be an office of the Trustee or an affiliate of the Trustee, Registrar or co-registrar) where Notes may be surrendered for registration of transfer or for exchange and where notices and demands to or upon the Company in respect of the Notes and this Indenture may be served. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company fails to maintain any such required office or agency or fails to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee.

The Company may also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission will in any manner relieve the Company of its obligation to maintain an office or agency for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

The Company hereby designates the Corporate Trust Office of the Trustee as one such office or agency of the Company in accordance with Section 2.03 hereof.

Section 4.03. SEC Reports.

CF Holdings and the Company shall file with the Trustee and the SEC, and transmit to Holders,

such information, documents and other reports, and such summaries thereof, as would be required pursuant to the TIA if this Indenture were qualified under the TIA at the times and in the manner provided in the TIA; provided that, unless available on EDGAR (or any successor system for the submission of documents to the SEC in electronic format), any such information, documents or reports required to be filed with the SEC pursuant to Section 13 or 15(d) of the Exchange Act shall be filed with the Trustee within 30 days after the same is filed with the SEC. In addition, to the extent not satisfied by the foregoing, the Company shall, for so long as any Notes are outstanding, furnish to the Holders of Notes and to prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

Delivery of reports, information and documents to the Trustee hereunder is for informational purposes only and the Trustee’s receipt of any such reports, information and documents shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates or statements delivered to the Trustee pursuant to Section 4.04 hereof). The Trustee shall not be obligated to monitor or confirm, on a continuing basis or otherwise, CF Holdings’ or the Company’s compliance with the covenants or with respect to any reports or other documents filed with the SEC pursuant to this Indenture, or participate in any conference calls.

Section 4.04. Compliance Certificate.

(a) The Company shall deliver to the Trustee, within 120 days after the end of each fiscal year ended after the Issue Date, a brief certificate (which need not comply with Section 13.04 hereof) from the Company’s principal executive officer, principal financial officer or principal accounting officer as to his or her knowledge of the Company’s compliance with this Indenture.

(b) So long as any of the Notes are outstanding, the Company will deliver to the Trustee, within 15 Business Days after an Executive Officer of either CF Holdings or the Company becomes aware of any Default or Event of Default, a statement specifying such Default or Event of Default and what action the Company is taking or proposes to take with respect thereto.

Section 4.05. [Intentionally Omitted].

Section 4.06. Stay, Extension and Usury Laws.

The Company and each of the Guarantors covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and the Company and each of the Guarantors (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law has been enacted.

Section 4.07. Limitation on Dispositions of Collateral.

Prior to the occurrence of an Investment Grade Rating Event, CF Holdings will not, and will not permit the Company or any Subsidiary Guarantor to, make any Disposition except:

(a) Dispositions of obsolete, used, uneconomical, retired, worn out or surplus property, or property no longer useful in the business of CF Holdings and its Subsidiaries or economically impracticable to maintain, in each case whether now owned or hereafter acquired, in the ordinary course of business;

The Company shall comply with the requirements of Rule 14e-l under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Disposition of any Collateral. To the extent that the provisions of any securities laws or regulations conflict with this Section 4.07, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 4.07 or the Notes by virtue of such compliance.

Section 4.08. Offer to Repurchase Upon Change of Control Repurchase Event.

(a) If a Change of Control Repurchase Event occurs, unless the Company has exercised its right to redeem the Notes pursuant to Section 3.07 hereof, the Company will make an offer (a “Change of Control Offer”) to each Holder to repurchase all or any part (equal to $2,000 or integral multiples of $1,000 in excess of $2,000) of that Holder’s Notes at a purchase price in cash equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest, if any, on the Notes repurchased to, but not including, the date of repurchase (the “Change of Control Payment”). Notwithstanding the foregoing, installments of interest on Notes that are due and payable on Interest Payment Dates falling on or prior to a Change of Control Payment Date will be payable on the Interest Payment Date to the Holders as of the close of business on the relevant Record Date. Within 30 days following any Change of Control

Repurchase Event, the Company shall mail (or with respect to Global Notes, to the extent permitted or required by applicable DTC procedures or regulations, send electronically) a notice to each Holder (and shall provide a copy of such notice to the Trustee):

(1) describing the transaction or transactions that constitute the Change of Control Repurchase Event;

(2) offering to repurchase Notes on the date specified in the notice (the “Change of Control Payment Date”), which date shall be no earlier than 30 days and no later than 60 days from the date such notice is mailed or sent; and

(3) stating the instructions determined by the Company, consistent with this Section 4.08, that a Holder must follow in order to have its Notes purchased.

(b) The Company shall comply with the requirements of Rule 14e-l under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Repurchase Event. To the extent that the provisions of any securities laws or regulations conflict with this Section 4.08, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 4.08 or the Notes by virtue of such compliance.

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

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

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

(d) The Company shall publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

(e) Notwithstanding anything to the contrary in this Section 4.08, the Company shall not be required to make a Change of Control Offer upon a Change of Control Repurchase Event 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 Section 4.08 and purchases all of the Notes properly tendered and not withdrawn under the Change of Control Offer.

Section 4.09. Limitation on Liens.

(a) Prior to an Investment Grade Rating Event, neither CF Holdings nor any of its Subsidiaries will create, incur, assume or permit to exist any Lien securing Indebtedness on or with respect to the Collateral except for Permitted Liens. Additionally, subject to the terms of the Intercreditor Agreement, prior to an Investment Grade Rating Event, neither CF Holdings nor any of its Subsidiaries shall create, incur, assume or permit to exist any Lien securing Indebtedness on or with respect to the Principal Property that is not Collateral, except for Permitted Liens, unless the Notes are secured equally

and ratably with the Indebtedness secured by such Lien for so long as such other Indebtedness is so secured (any such Lien so securing other Indebtedness, an “Initial Lien”).

(b) Following an Investment Grade Rating Event, except as described in Section 4.11, neither CF Holdings nor any of its Subsidiaries will create, incur, assume or permit to exist any Lien securing Indebtedness on or with respect to any Principal Property, except for Permitted Liens, or unless the Notes are secured equally and ratably with the Indebtedness secured by such Lien for so long as such other Indebtedness is so secured (any such Lien so securing other Indebtedness, an “Initial Lien”).

(c) Any Lien created for the benefit of the Holders pursuant to the final sentence of Section 4.09(a) or the final sentence of Section 4.09(b) shall provide by its terms that such Lien shall be automatically and unconditionally released and discharged upon the release and discharge of the Initial Lien.

(d) For purposes of determining compliance with this Section 4.09, (a) a Lien securing Indebtedness need not be permitted solely by reference to the provisions set forth in Section 4.09(a) with respect to the exceptions described in Section 4.11, or to one category (or portion thereof) of Permitted Liens, but may be permitted in part under any combination thereof and (b) in the event that a Lien securing Indebtedness (or any portion thereof) meets the criteria of one or more of the categories of Permitted Liens or pursuant to one of the provisions set forth in Section 4.09(a) with respect to the exceptions described in Section 4.11, the Company may, in its sole discretion, classify or divide such Lien securing such Indebtedness (or any portion thereof) in any manner that complies with such covenant.

Section 4.10. Limitation on Sale and Leaseback Transactions.

Except as provided under Section 4.11 hereof, CF Holdings shall not, and shall not permit any of its Subsidiaries to, enter into any Sale and Leaseback Transaction with respect to a Principal Property and with a lease exceeding three years, other than leases between or among CF Holdings and its Subsidiaries, unless:

(1) CF Holdings and/or such Subsidiary or Subsidiaries would be entitled to incur Indebtedness in an amount equal to or greater than the Attributable Debt in respect of such Sale and Leaseback Transaction secured by a Lien on such Principal Property pursuant to one or more categories of the definition of “Permitted Liens”; and

(2) within 120 days after such Sale and Leaseback Transaction, CF Holdings or such Subsidiary applies an amount equal to the greater of the net proceeds of such Sale and Leaseback Transaction and the Fair Market Value at the time of such Sale and Leaseback Transaction of the Principal Property so leased to the retirement of Funded Debt of CF Holdings or any of its Subsidiaries or the purchase, acquisition or, in the case of real property, construction of other property that will constitute Principal Property.

Section 4.11. Exemption from Limitations on Liens and Sale and Leaseback Transactions.

Following an Investment Grade Rating Event, CF Holdings and its Subsidiaries may incur Indebtedness secured by Liens or enter into Sale and Leaseback Transactions that would not otherwise be permitted under Sections 4.09 and 4.10 hereof; provided that, immediately after giving effect thereto, the amount of outstanding Indebtedness so incurred secured by a Lien (other than a Permitted Lien) upon any Principal Property (now owned or hereafter acquired) without equally and ratably securing the Notes pursuant to Section 4.09 hereof, plus the aggregate amount of all outstanding Attributable Debt with respect to all such Sale and Leaseback Transactions (not including those that are for less than three years

or in respect of which Funded Debt is retired or property that will constitute Principal Property is purchased, as provided under Section 4.10 hereof), does not exceed 15% of Consolidated Total Assets.

Section 4.12. Additional Note Guarantees.

Subject to Section 10.06, if any Subsidiary of CF Holdings other than the Company becomes a borrower or directly or indirectly guarantees any Indebtedness under the Credit Agreement, CF Holdings shall cause such Subsidiary to, within 90 days, execute and deliver to the Trustee a supplemental indenture substantially in the form of Exhibit D hereto, pursuant to which such Subsidiary will guarantee payment of the Notes on the terms and conditions set forth in Article 10 hereof, and cause such Guarantor to comply with the provisions of Section 11.02. Thereafter, such Subsidiary will be a Subsidiary Guarantor with respect to the Notes until such Subsidiary’s Note Guarantee is released in accordance with this Indenture.

Section 4.13. No Impairment of the Security Interests.

Other than in connection with transactions not prohibited by the Note Documents, subject to the terms of the Intercreditor Agreement, none of the Company or any Guarantor will be permitted to take any action, or knowingly or negligently omit to take any action, which action or omission would have the result of materially impairing the security interest with respect to the Collateral for the benefit of the Collateral Agent, the Trustee and the Holders of the Notes.

Any release of Collateral in accordance with the provisions of this Indenture and the Collateral Documents will not be deemed to impair the security hereunder or thereunder.

Section 4.14. [Intentionally Omitted].

Section 4.15. Further Assurances.

Subject to the applicable limitations set forth herein and in the Collateral Documents, the Company and each Guarantor shall execute any and all further documents, financing statements, applications for registration, agreements and instruments, and take all such further actions that may be required under any applicable law, or that the Collateral Agent may reasonably request, pursuant to the terms of the Collateral Documents, in order to grant, preserve, protect and perfect the validity and priority of the security interests created or intended to be created by the applicable Collateral Documents in the Collateral, to the extent and within the time period required by the applicable Collateral Documents, all at the expense of the Company and Guarantors and provide to the Collateral Agent and the Trustee, from time to time upon reasonable request, evidence reasonably satisfactory to the Collateral Agent and the Trustee as to the perfection and priority of the Liens created or intended to be created by the Collateral Documents.

ARTICLE 5
CONSOLIDATION, MERGER OR SALE OF ASSETS

Section 5.01. Merger Consolidation or Sale of Assets.

(a) Neither CF Holdings nor the Company will, directly or indirectly: (1) consolidate or merge with or into another Person, other than the Company or CF Holdings, respectively (whether or not CF Holdings or the Company, as the case may be, is the surviving corporation), or (2) sell, assign, transfer, convey, lease or otherwise dispose of all or substantially all of the properties or assets of CF

Holdings and its Subsidiaries, taken as a whole, in one or more related transactions, to another Person, unless:

(1) either (a) CF Holdings or the Company, as the case may be, is the survivor formed by or resulting from such consolidation or merger or (b) the surviving or successor entity is a corporation or limited liability company organized or existing under the laws of the United States, any State of the United States or the District of Columbia;

(2) the surviving or successor entity (if other than CF Holdings or the Company, as the case may be) or the person to which such sale, assignment, transfer, conveyance or other disposition has been made assumes all the obligations of CF Holdings or the Company, as the case may be, under the Notes and this Indenture pursuant to a supplemental indenture reasonably satisfactory to the Trustee, and shall pursuant to supplements to the Collateral Documents take such action as may be required to assume the obligations of CF Holdings or the Company, as the case may be, thereunder and maintain the perfection of the Liens securing the Collateral;

(3) immediately after completion of the transaction, no Default or Event of Default has occurred and is continuing; and

(4) the surviving or successor entity shall have delivered to the Trustee an Officers’ Certificate and Opinion of Counsel, each stating that such transaction and any supplemental indenture entered into in connection with such transaction comply with this Section 5.01 and that all conditions precedent in this Indenture relating to such transaction have been complied with, and an Opinion of Counsel stating that the Notes and this Indenture constitute valid and legally binding obligations of the Company or surviving entity, as applicable, subject to customary exceptions.

Section 5.02. Successor Corporation Substituted.

Upon any consolidation or merger, or any sale, assignment, transfer, lease, conveyance or other disposition of all or substantially all of the properties or assets of CF Holdings or the Company in a transaction that is subject to, and that complies with the provisions of, Section 5.01 hereof, the successor Person formed by such consolidation or into or with which CF Holdings or the Company is merged or to which such sale, assignment, transfer, lease, conveyance or other disposition is made shall succeed to, and be substituted for (so that from and after the date of such consolidation, merger, sale, assignment, transfer, lease, conveyance or other disposition, in the case of CF Holdings the provisions of this Indenture referring to the “CF Holdings” shall refer instead to the surviving or successor Person and not to CF Holdings and in the case of the Company the provisions of this Indenture referring to the “Company” shall instead refer to such surviving or successor Person and not the Company), and may exercise every right and power of CF Holdings or the Company, as the case may be, under this Indenture with the same effect as if such successor Person had been named as CF Holdings or the Company, as applicable, herein (except that the Company or its successor pursuant to this Section 5.02 shall not be required to be a Guarantor), and thereafter the predecessor Person shall be released and discharged of all obligations and covenants under this Indenture and the Notes or the Note Guarantees, as applicable, and shall be released from all applicable Collateral Documents, and any applicable Collateral shall be released as provided in the applicable Collateral Documents; provided, however, that (1) the predecessor CF Holdings shall not be released from its obligations with respect to its Note Guarantee and Collateral Documents and (2) the predecessor Company shall not be released from the obligation to pay the principal of and interest on the Notes, except, in each case, upon a sale of all of CF Holdings’ or the Company’s assets in a transaction that is subject to, and that complies with the provisions of, Section 5.01 hereof.

ARTICLE 6
DEFAULT AND REMEDIES

Section 6.01. Events of Default.

(a) Each of the following is an “Event of Default”:

(1) default for 30 days in the payment when due of interest on the Notes;

(2) default in the payment when due (at maturity, upon redemption or otherwise) of the principal of, or premium, if any, on, the Notes;

(3) subject to clause (b) of this Section 6.01, failure by CF Holdings or any of its Subsidiaries to comply with any other covenant or other agreement in this Indenture or any term in the Notes for 60 days after notice to the Company from the Trustee or to the Company and the Trustee from the Holders of at least 25% in aggregate principal amount of the Notes then outstanding;

(4) default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by CF Holdings or any of its Subsidiaries (or the payment of which is guaranteed by CF Holdings or any of its Subsidiaries), whether such Indebtedness exists on or prior to or is created after the Issue Date (in each case other than the Note Documents), if that default:

(A) is caused by a failure to pay principal when due at final (and not any interim) maturity of such Indebtedness on or prior to the expiration of the grace period provided in such Indebtedness (a “Payment Default”); or

(B) results in the acceleration of such Indebtedness prior to its Stated Maturity (without such acceleration having been rescinded, annulled or otherwise cured);

and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated (without such acceleration having been rescinded, annulled or otherwise cured), aggregates $150.0 million or more;

(5) any Note Guarantee of CF Holdings or a Significant Subsidiary of CF Holdings is held in any judicial proceeding to be unenforceable or invalid or, except as permitted by this Indenture, ceases for any reason to be in full force and effect, or CF Holdings or any Subsidiary Guarantor, or any Person acting on behalf of any Subsidiary Guarantor, that is a Significant Subsidiary of CF Holdings denies or disaffirms its obligations under its Note Guarantee, in each case for any reason other than by reason of release pursuant to the terms of this Indenture or the terms of any other Note Document;

(6) any Lien purported to be created under any Collateral Document shall cease to be, or shall be asserted by the Company or any Guarantor not to be, a valid and perfected Lien on any Collateral having an aggregate Fair Market Value of $250.0 million or more, with the priority required by the relevant Collateral Document, in each case for any reason other than (A) by reason of release pursuant to the terms of this Indenture or the terms of any Collateral Document or (B) as a result of the sale or other disposition of the applicable Collateral to a Person that is not the Company or a Guarantor in a transaction not prohibited under this Indenture; or

(7) CF Holdings or any of its Subsidiaries that is a Significant Subsidiary of CF Holdings or any group of Subsidiaries of CF Holdings that, taken together, would constitute a Significant Subsidiary of CF Holdings, pursuant to or within the meaning of Bankruptcy Law:

(A) commences a voluntary case,

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

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

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

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

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

(B) appoints a custodian of CF Holdings or any of its Subsidiaries that is a Significant Subsidiary of CF Holdings or any group of Subsidiaries of CF Holdings that, taken together, would constitute a Significant Subsidiary of CF Holdings; or

(C) orders the liquidation of CF Holdings or any of its Subsidiaries that is a Significant Subsidiary of CF Holdings or any group of Subsidiaries of CF Holdings that, taken together, would constitute a Significant Subsidiary of CF Holdings;

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

(b) Notwithstanding clause (3) of Section 6.01(a) hereof or any other provision of this Indenture, the sole remedy for any failure by CF Holdings or the Company to comply with Section 4.03 hereof will be the payment of Liquidated Damages as described in the following sentence and the final sentence of this clause (b), such failure to comply shall not constitute a Default or Event of Default, and Holders will not have any right to accelerate the maturity of the Notes as a result of any such failure to comply. If a failure by CF Holdings or the Company to comply with Section 4.03 hereof continues for 180 consecutive days after the Company receives from the Trustee, or the Company and the Trustee receive from the Holders of at least 25% in aggregate principal amount of the Notes then outstanding, notice of such failure to comply (such notice, a “Reports Default Notice”), the Company will pay liquidated damages (“Liquidated Damages”) to all Holders at a rate per annum equal to 0.25% of the principal amount of the Notes from the 180th day following the Company’s receipt of such Reports Default Notice to but not including the date on which such failure to comply shall have been cured or waived (and, on such date, Liquidated Damages will cease to accrue). A failure to comply with Section 4.03 hereof automatically will cease to be continuing and will be deemed cured at such time as CF Holdings or the Company, as applicable, files with the SEC (or, if the SEC will not accept such filing, delivers to Holders or otherwise makes publicly available) the applicable annual report, information, document or other report. In no event will the Company be required to pay Liquidated Damages at a rate

in excess of 0.25% of the principal amount of the Notes per annum, irrespective of the number of Reports Default Notices that may have been received and irrespective of the number of failures to comply with Section 4.03 hereof that may be continuing.

(c) All accrued and unpaid Liquidated Damages, if any, shall be paid by the Company on the next scheduled Interest Payment Date in the same manner as interest on the Notes is payable on such date. In the case of any Reports Default Notice given by Holders, such Holders shall provide a copy of such Reports Default Notice to the Trustee. If Liquidated Damages are payable on the Notes, the Company shall provide an Officers’ Certificate to the Trustee on or before the Record Date for each Interest Payment Date such Liquidated Damages are payable setting forth the accrual period and the amount of such Liquidated Damages in reasonable detail, provided that the failure to deliver such Officers’ Certificate shall not constitute a Default or Event of Default. Unless and until a Responsible Officer of the Trustee receives at the Corporate Trust Office such a certificate, the Trustee may assume without inquiry that no such Liquidated Damages are payable. If the Company has paid Liquidated Damages directly to the Persons entitled to it, the Company shall deliver to the Trustee an Officers’ Certificate setting forth the particulars of such payment, provided that the failure to deliver such Officers’ Certificate shall not constitute a Default or Event of Default.

(d) Any Default or Event of Default for the failure to deliver any notice or certificate pursuant to any provision of this Indenture shall be deemed to be cured upon the filing, furnishing or delivery of any such notice or certificate, as applicable, even though such delivery is not within the prescribed period specified in this Indenture.

Section 6.02. Acceleration.

In the case of an Event of Default specified in clause (7) or (8) of Section 6.01(a) hereof, with respect to CF Holdings or any of its Subsidiaries that is a Significant Subsidiary of CF Holdings or any group of Subsidiaries of CF Holdings that, taken together, would constitute a Significant Subsidiary of CF Holdings, all outstanding Notes will become due and payable immediately without further action or notice. If any other Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately by written notice to the Company (and to the Trustee if given by Holders) specifying such Event of Default. Upon any such declaration, the Notes shall become due and payable immediately.

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

Section 6.03. Other Remedies.

If an Event of Default with respect to the Notes occurs and is continuing, the Trustee may pursue, in its own name or as trustee of an express trust, any available remedy by proceeding at law or in equity to collect the payment of principal of, premium, if any, and interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture or the other Note Documents, subject to the terms of the Intercreditor Agreement.

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.

Section 6.04. Waiver of Past Defaults.

Subject to Sections 6.02, 6.07 and Section 9.02 hereof, the Holders of a majority in aggregate principal amount of the outstanding Notes (voting as a single class), by notice to the Trustee, may, on behalf of the Holders of all of the Notes, waive an existing Default or Event of Default with respect to the Notes and its consequences, except a Default or Event of Default in the payment of principal of, premium or interest, if any, on any Notes as specified in clause (1) or (2) of Section 6.01(a) hereof. Upon any such waiver, such Default shall cease to exist, and any Event of Default with respect to the Notes arising therefrom shall be deemed to have been cured for every purpose of this Indenture and the Company, Trustee and Holders restored to their former position and rights hereunder; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any contractual right consequent thereto.

Section 6.05. Control by Majority.

Subject to Sections 7.01 and 7.02(f) and the Intercreditor Agreement, the Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee with respect to the Notes by this Indenture or the Collateral Documents. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture, that the Trustee determines may be unduly prejudicial to the rights of Holders not joining in the giving of such direction (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not any such directions are unduly prejudicial to such Holders) or that may involve the Trustee in personal liability. The Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction.

Section 6.06. Limitation on Suits.

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

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

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

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

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

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

For the avoidance of doubt and notwithstanding any other provision of this Indenture or the Notes, (x) the Holders of the Notes shall not be entitled to specific performance of Sections 3.01, 3.02, 3.03, 3.04, 3.05, 3.06 or 3.07 hereof, and no premium will

be due or available as a remedy, in each case in connection with (1) any Default or Event of Default or (2) any acceleration (automatic or otherwise) of all, or any portion of, the Notes (other than an acceleration in respect of an Event of Default for failing to pay the redemption price when due following the Company’s voluntary election, if any, to redeem the Notes pursuant to Article 3 hereof, to the extent any premium is due in connection therewith), and (y) the requirement to pay any premium shall only arise in connection with the Company’s voluntary election, if any, to redeem the Notes pursuant to Article 3 hereof, and not in connection with any other payment, distribution, satisfaction or other recovery in respect of the Notes.

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

Notwithstanding any other provision of this Indenture, the contractual right of any Holder of a Note to receive payment of principal, premium, if any, and 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 amended without the consent of such Holder.

Section 6.08. Collection Suit by Trustee.

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

Section 6.09. Trustee May File Proofs of Claim.

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

Section 6.10. Application of Proceeds.

If the Trustee or the Collateral Agent, as the case may be, collects any money or property pursuant to this Article 6 (including upon any realization of any Lien upon Collateral), or after an Event of Default any moneys or properties distributable in respect of the Company’s or any Guarantor’s obligations under this Indenture, it shall, subject to the terms of the Intercreditor Agreement, pay out the money or property in the following order:

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

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

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

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

Section 6.11. Restoration of Rights and Remedies.

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

Section 6.12. 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 Trustee, a court in its discretion may require any party litigant in such suit to file an undertaking to pay the costs of the suit, and the court may assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in the suit having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.12 does not apply to a suit by a Holder pursuant to Section 6.07 hereof, a suit instituted by the Trustee or a suit by Holders of more than 10% in principal amount of the then outstanding Notes.

Section 6.13. Rights and Remedies Cumulative.

Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or wrongfully taken Notes in Section 2.08 hereof, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

Section 6.14. Delay or Omission not Waiver.

No delay or omission of the Trustee or of any Holder to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Subject to Section 6.06 hereof, every right and remedy given by this Article 6 or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

ARTICLE 7
TRUSTEE

Section 7.01. Duties of Trustee.

(a) If an Event of Default has occurred and is continuing, the Trustee will exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs.

(b) Except during the continuance of an Event of Default:

(1) the duties of the Trustee will be determined solely by the express provisions of this Indenture and the Trustee need perform only those duties that are specifically set forth in this Indenture and no others, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

(2) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture (but need not confirm or investigate the accuracy of any mathematical calculations or other facts stated therein). However, the Trustee will examine the certificates and opinions to determine whether or not they conform to the requirements of this Indenture.

(c) The Trustee may not be relieved from liabilities for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that:

(1) this paragraph does not limit the effect of paragraph (b) of this Section 7.01;

(2) the Trustee will not be liable for any error of judgment made in good faith by a Responsible Officer, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and

(3) the Trustee will not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.05 hereof.

(d) Whether or not therein expressly so provided, every provision of this Indenture that in any way relates to the Trustee is subject to paragraphs (a), (b), and (c) of this Section 7.01.

(e) No provision of this Indenture will require the Trustee to expend or risk its own funds or incur any liability. The Trustee will be under no obligation to exercise any of its rights and powers under this Indenture or the Collateral Documents at the request of any Holders, unless such Holder has offered to the Trustee security and indemnity satisfactory to it against any loss, liability or expense. The Trustee

shall not be required to give any bond or surety in respect of the performance of its powers or duties hereunder. The permissive right of the Trustee to do things enumerated in this Indenture shall not be construed as a duty of the Trustee.

(f) The Trustee will not be liable for interest on any money received by it except as the Trustee may agree in writing with the Company. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law.

(g) Upon the occurrence and continuance of an Event of Default, before taking any foreclosure action or any action which may subject the Trustee or the Collateral Agent, as applicable, to liability under any environmental law, statute, regulation or similar requirement, the Trustee or Collateral Agent, as applicable, may require that a satisfactory indemnity bond, indemnity or environmental impairment insurance be furnished for the payment or reimbursement of all expenses to which they may be put and to protect it against all liability resulting from any claims, judgments, damages, losses, penalties, fines, liabilities (including strict liability) and expenses which may result from such foreclosure or other action, and will not be required to foreclose if doing so will subject them to environmental liability or will require the approval of a governmental regulator that cannot be obtained.

(h) No provision of this Indenture or the Note Documents shall require the Trustee or the Collateral Agent to be obligated to take any action in a jurisdiction that would cause it to pay any tax or obligate it to qualify to do business if it is not then so qualified.

Section 7.02. Rights of Trustee.

(a) The Trustee may conclusively rely upon any document (whether in original or facsimile form) believed by it to be genuine and to have been signed or presented by the proper Person. The Trustee need not investigate any fact or matter stated in the document.

(b) Before the Trustee acts or refrains from acting, it may require an Officers’ Certificate or an Opinion of Counsel or both. The Trustee will not be liable for any action it takes or omits to take in good faith in reliance on any Officers’ Certificate, Opinion of Counsel, resolution of the Board of Directors, or other request, notice or direction delivered to it pursuant to the terms of this Indenture. The Trustee may consult with counsel and the written advice of such counsel or any Opinion of Counsel will be full and complete authorization and protection from liability in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon.

(c) The Trustee may act through its attorneys and agents and will not be responsible for the misconduct or negligence of any agent appointed with due care.

(d) The Trustee will not be liable for any action it takes or omits to take in good faith that it believes to be authorized or within the rights or powers conferred upon it by this Indenture and any Collateral Documents.

(e) Unless otherwise specifically provided in this Indenture, any demand, request, direction or notice from the Company will be sufficient if signed by an Officer of the Company.

(f) The Trustee will be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders unless such Holders have offered to the Trustee an indemnity or security satisfactory to it against the losses, liabilities and expenses that might be incurred by it in compliance with such request or direction.

(g) Subject to Section 7.01 hereof, the rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be compensated, reimbursed and indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, the Collateral Agent in each of its capacities hereunder, and each Agent and Custodian.

(h) Subject to Section 7.01 hereof, the Trustee shall not be deemed to have knowledge or notice of any Default or Event of Default unless a Responsible Officer of the Trustee has actual knowledge thereof or unless the Company or Holders of not less than 25% in aggregate principal amount of the Notes then outstanding notify the Trustee thereof by written notice of such event sent to the Trustee in accordance with Section 13.01, and such notice references the Notes and this Indenture.

(i) Subject to Section 7.01(a) hereof, the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of Indebtedness or other paper or document, but the Trustee, may, but shall not be required to, make further inquiry or investigation into such facts or matters as it may see fit.

(j) In no event shall the Trustee be responsible or liable for any failure or delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation, strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services; it being understood that the Trustee shall use reasonable efforts which are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances.

(k) The Trustee shall not be liable for any action it takes or omits to take in good faith that it believes to be authorized or within the rights or powers conferred upon it by this Indenture.

(m) In no event shall the Trustee be responsible or liable for any special, indirect, punitive or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit), irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action.

Section 7.03. Individual Rights of Trustee.

The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Company or any Affiliate of the Company with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest (as defined in the TIA; provided that the 2026 Indenture shall not constitute such a conflict of interest) it must eliminate such conflict within 90 days or resign as provided in this Indenture. Any Agent may do the same with like rights and duties. The Trustee is also subject to Section 7.10 hereof.

Section 7.04. Trustee’s Disclaimer.

The Trustee will not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Notes or the Note Guarantees, it shall not be accountable for the Company’s use

of the proceeds from the Notes or any money paid to the Company or upon the Company’s direction under any provision of this Indenture, it will not be responsible for the use or application of any money received by any Paying Agent other than the Trustee, and it will not be responsible for any statement or recital herein or any statement in the Notes or in the Offering Memorandum or any other document in connection with the sale of the Notes or pursuant to this Indenture other than its certificate of authentication. The Trustee shall not be bound to ascertain or inquire as to the performance, observance, or breach of any covenants, conditions, representations, warranties or agreements on the part of the Company or the Guarantors but the Trustee may require full information and advice as to the performance of the aforementioned covenants. Under no circumstances shall the Trustee be liable in its individual capacity for the obligations evidenced by the Notes or the Note Guarantees.

None of the Trustee, the Collateral Agent, nor any paying agent shall be responsible for monitoring the Company’s rating status, making any request upon any Rating Agency, or determining whether any Ratings Downgrade or Investment Grade Rating Event has occurred. The Trustee and the Collateral Agent shall not be responsible for and make no representation as to the existence, genuineness, value or protection of or insurance with respect to any Collateral, for the legality, effectiveness or sufficiency of any Collateral Document or Note Document, for any act or omission of the Credit Agreement Agent, or for the creation, perfection, priority, sufficiency or protection of any Liens securing the Notes Obligations. The Trustee and the Collateral Agent shall not be responsible for filing any financing or continuation statements or recording any documents or instruments in any public office at any time or times or otherwise perfecting or maintaining the perfection of any Lien or security interest in the Collateral. The Trustee and the Collateral Agent shall not be liable or responsible for the failure of the Company to effect or maintain insurance on the Collateral nor shall it be responsible for any loss by reason of want or insufficiency in insurance or by reason of the failure of any insurer in which the insurance is carried to pay the full amount of any loss against which it may have insured the Company, the Trustee or any other person.

Section 7.05. Notice of Defaults.

If a Default or Event of Default occurs and is continuing and if it is known to a Responsible Officer of the Trustee, the Trustee will mail to Holders a notice of the Default or Event of Default within 90 days after it occurs or, if discovered after 90 days, promptly thereafter. Except in the case of a Default or Event of Default in payment of principal of, premium, if any, or interest on, any Note, the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders.

Section 7.06. [Intentionally Omitted].

Section 7.07. Compensation and Indemnity.

(a) The Company will pay to the Trustee and the Collateral Agent from time to time reasonable compensation for its acceptance of this Indenture and services hereunder and under the other Note Documents. Neither the Trustee’s nor the Collateral Agent’s compensation will be limited by any law on compensation of a trustee of an express trust. The Company will reimburse the Trustee and the Collateral Agent promptly upon request for all reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. All amounts set forth in the separate fee letter entered into prior to the date hereof are deemed reasonable. Such expenses will include the reasonable compensation, disbursements and expenses of the Trustee’s and the Collateral Agent agents and counsel.

(b) The Company and the Guarantors will, jointly and severally, indemnify the Trustee and the Collateral Agent against any and all losses, damages, liabilities or expenses incurred by such Person arising out of or in connection with the acceptance or administration of its duties under this Indenture or any other Note Document, including the costs and expenses of enforcing this Indenture against the Company and the Guarantors (including this Section 7.07) and defending itself against any claim (whether asserted by the Company, the Guarantors, any Holder or any other Person) or liability in connection with the exercise or performance of any of its rights, powers or duties hereunder or under any other Note Document, except to the extent any such loss, liability or expense may be attributable to its negligence or willful misconduct as finally adjudicated by a court of competent jurisdiction. The Trustee or the Collateral Agent, as applicable, will notify the Company promptly of any claim for which such Person may seek indemnity. Failure by the Trustee or the Collateral Agent, as applicable, to so notify the Company will not relieve the Company or any of the Guarantors of their obligations hereunder. The Company or such Guarantor will defend the claim and the Trustee or the Collateral Agent, as applicable, will cooperate in the defense. The Trustee or the Collateral Agent, as applicable, may have separate counsel and the Company will pay the reasonable fees and expenses of such counsel. Neither the Company nor any Guarantor need pay for any settlement made without its consent, which consent will not be unreasonably withheld.

(c) The obligations of the Company and the Guarantors under this Section 7.07 will survive the satisfaction and discharge of this Indenture and the earlier resignation or removal of the Trustee or the Collateral Agent. The negligence or willful misconduct of any Trustee hereunder shall not affect the rights of any other Trustee hereunder.

(d) To secure the Company’s and the Guarantors’ payment obligations in this Section 7.07, the Trustee will 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 will survive the satisfaction and discharge of this Indenture.

(e) When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(a)(7) or (8) 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 will 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 upon 30 days’ notice and be discharged from the trust hereby created by so notifying the Company. The Holders of a majority in aggregate principal amount of the then outstanding Notes may remove the Trustee upon 30 days’ notice by so notifying the Trustee and the Company in writing. The Company may remove the Trustee if:

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

(2) 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;

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

(4) 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 will promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in aggregate 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 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company, or the Holders of at least 10% in aggregate principal amount of the then outstanding Notes may petition 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 six months, fails to comply with Section 7.10 hereof, 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 will deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon, the resignation or removal of the retiring Trustee will become effective, and the successor Trustee will have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee will mail a notice of its succession to Holders. The retiring Trustee will 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 will continue for the benefit of the retiring Trustee.

Section 7.09. Successor Trustee by Merger, etc.

If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the successor corporation without any further act will be the successor Trustee.

Section 7.10. Eligibility.

There will at all times be a Trustee hereunder that is a corporation organized and doing business under the laws of the United States of America or of any state thereof that is authorized under such laws to exercise corporate trustee power, that is subject to supervision or examination by federal or state authorities and that has a combined capital and surplus of at least $100.0 million as set forth in its most recent published annual report of condition.

ARTICLE 8
LEGAL DEFEASANCE AND COVENANT DEFEASANCE

Section 8.01. Option to Effect Legal Defeasance or Covenant Defeasance.

The Company may at any time elect to have either Section 8.02 or 8.03 hereof be applied to all outstanding Notes and the Note Guarantees upon compliance with the conditions set forth below in this Article 8.

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 and each of the Guarantors will, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have been discharged from their obligations with respect to all outstanding Notes (including the Note Guarantees), and have Liens, if any, on the Collateral securing the Notes Obligations released, 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 will be deemed to have paid and discharged the entire Indebtedness represented by such outstanding Notes (including the Note Guarantees), which will thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 hereof and the other Sections of this Indenture referred to in clauses (1) and (2) below, and to have satisfied all their other obligations under such Notes, the Note Guarantees and this Indenture (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 will survive until otherwise terminated or discharged hereunder:

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

(2) the Company’s obligations with respect to the Notes under Sections 2.03, 2.04, 2.05, 2.06, 2.08, 2.09, 2.10, 2.11 and 4.02 hereof;

(3) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the obligations of the Company and each of the Guarantors in connection therewith; and

(4) this Article 8.

Subject to compliance with this Article 8, the Company may exercise its option under this Section 8.02 notwithstanding the prior exercise of its option under Section 8.03 hereof.

Section 8.03. Covenant Defeasance.

Upon the Company’s exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Company and each of the Guarantors will, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, 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 and Article 5 hereof, and have Liens, if any, on the Collateral securing the Notes Obligations released with respect to the outstanding Notes on the date the conditions set forth in Section 8.04 hereof are satisfied (hereinafter, “Covenant Defeasance”), and such Notes will 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 will continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes will not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes and Note Guarantees, the Company and the Guarantors may omit to comply with and will have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply will not constitute a Default or an Event of Default under Section 6.01(a) hereof, but, except as specified above, the remainder of this Indenture and such Notes and Note Guarantees will 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(a)(3), (4) and (5) hereof will not constitute Events of Default.

Section 8.04. Conditions to Legal or Covenant Defeasance.

In order to exercise either Legal Defeasance or Covenant Defeasance under either Section 8.02 or 8.03 hereof:

(1) the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders, cash in U.S. dollars, Government Securities, or a combination of cash in U.S. dollars and Government Securities, in amounts as will be sufficient, in the opinion of a nationally recognized investment bank, appraisal firm or firm of independent public accountants if Government Securities are delivered, to pay the principal of, or interest and premium, if any, on, the outstanding Notes on the stated date for payment thereof or on the applicable redemption date, as the case may be, and the Company must specify whether the Notes are being defeased to such stated date for payment or to a particular redemption date;

(2) in the case of Legal Defeasance, the Company must deliver to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that (A) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or (B) since the Issue Date, there has been a change in the applicable U.S. federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel will confirm that, the Beneficial Owners of the outstanding Notes will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such Legal Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

(3) in the case of Covenant Defeasance, the Company must deliver to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that the Beneficial Owners of the outstanding Notes will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such Covenant Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;

(4) no Default or Event of Default shall have occurred and be continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit);

(5) such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than this Indenture) to which CF Holdings or any of its Subsidiaries is a party or by which CF Holdings or any of its Subsidiaries is bound;

(6) the Company must deliver to the Trustee an Officers’ Certificate stating that the deposit was not made by the Company with the intent of preferring the Holders over the other creditors of the Company with the intent of defeating, hindering, delaying or defrauding any creditors of the Company or others; and

(7) the Company must deliver to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with.

Section 8.05. Deposited Money and Government Securities to be Held in Trust; Other Miscellaneous Provisions.

Subject to Section 8.06 hereof, all money and Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.05, the “Trustee”) pursuant to Section 8.04 hereof in respect of any Notes to be defeased will be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium, if any, and interest, but such money need not be segregated from other funds except to the extent required by law.

The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or Government Securities deposited pursuant to Section 8.04 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of such Notes.

Notwithstanding anything in this Article 8 to the contrary, the Trustee shall deliver or pay to the Company from time to time upon the request of the Company any money or Government Securities held by it as provided in Section 8.04 hereof which, in the opinion of a nationally recognized investment bank, appraisal firm or firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(1) hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

Section 8.06. Repayment to 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, premium, if any, or interest has become due and payable shall, subject to applicable abandoned property law, be paid to the Company on its request or (if then held by the Company) will be discharged from such trust; and the Holder of such Note will thereafter be permitted to 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, will thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the 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 will not be less than 30 days from the date of such notification or publication, any unclaimed balance of such money then remaining will be repaid to the Company.

Section 8.07. Reinstatement.

If the Trustee or Paying Agent is unable to apply any cash in U.S. dollars or Government Securities 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 and the Guarantors’ obligations under this Indenture, the Notes and the Note Guarantees affected thereby will 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 makes any payment of principal of, premium, if any, or interest on, any Note following the reinstatement of its obligations, the Company will 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.

(12) to mortgage, pledge, hypothecate or grant any other Lien in favor of the Collateral Agent with respect to the Notes for its benefit and the benefit of the Trustee, the Holders of the Notes and the holders of any other First-Priority Lien Obligations, as additional security for the payment and performance of all or any portion of the First-Priority Lien Obligations, in any property or assets, including any which are required to be mortgaged, pledged or hypothecated, or in which a Lien is required to be granted to or for the benefit of the Trustee or the Collateral Agent pursuant to this Indenture, the Collateral Documents or otherwise;

Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental indenture, and upon receipt by the Trustee and/or the Collateral Agent, as applicable, of the documents described in Section 7.02 hereof, the Trustee and/or the Collateral Agent, as applicable, will join with the Company and the Guarantors in the execution of any amended or supplemental indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee and/or the Collateral Agent, as applicable, will not be obligated to enter into such amended or supplemental indenture that adversely affects its own rights, duties or immunities under this Indenture or otherwise.

Section 9.02. With Consent of Holders.

Except as provided in this Section 9.02, the Note Documents may be amended with the consent of the Holders of at least a majority in aggregate principal amount of the then outstanding Notes (including, without limitation, Additional Notes, if any) (in addition to any other consents required under the terms of the Intercreditor Agreement or the other Collateral Documents from the parties thereto) voting as a single class (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, or purchase of, such Notes), and any existing Default or Event of Default or

compliance with any provisions of such Note Documents may be waived with the consent of the Holders of at least a majority in aggregate principal amount of the then outstanding Notes (including, without limitation, Additional Notes, if any) voting as a single class (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, or purchase of, such Notes). Section 2.09 hereof shall determine which Notes are to be considered “outstanding” for purposes of this Section 9.02.

Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee and/or the Collateral Agent, as applicable, will join with the Company and the Guarantors in the execution of such amended or supplemental indenture unless such amended or supplemental indenture directly adversely affects the rights, duties or immunities of the Trustee and/or the Collateral Agent, as applicable, under this Indenture or otherwise, in which case the Trustee and/or the Collateral Agent, as applicable, may in their respective discretion, but will not be obligated to, enter into such amended or supplemental indenture. It is not necessary for the consent of the Holders under this Section 9.02 to approve the particular form of any proposed amendment, supplement or waiver, but it is sufficient if such consent approves the substance thereof.

After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Company will mail to the Holders a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, will not, however, in any way impair or affect the validity of any such amended or supplemental indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a majority in aggregate principal amount of the Notes then outstanding voting as a single class may waive compliance in a particular instance by the Company with any provision of this Indenture or such Notes or Note Guarantees.

However, without the consent of each Holder affected, an amendment, supplement or waiver under this Section 9.02 may not (with respect to any Notes held by a non-consenting Holder):

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

(2) reduce the principal of or change the fixed maturity of any Note;

(3) amend, change or modify in any material respect the obligation of the Company to make and consummate a Change of Control Offer after the occurrence of a Change of Control Repurchase Event;

(4) reduce the premium payable upon the redemption of any Note or change the time at which any Note may be redeemed to an earlier time, in each case as described above under Article 3;

(5) reduce the stated rate of or extend the stated time for payment of interest, including default interest, on any Note;

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

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

(8) make any changes in the contractual provisions of this Indenture relating to waivers of past Defaults or the rights of Holders to receive payments of principal of, or interest or premium, if any, on, any Note;

(9) release any Guarantor that is a Significant Subsidiary of CF Holdings from any of its contractual obligations under its Note Guarantee or this Indenture, except in accordance with the terms of this Indenture; or

(10) make any change in the preceding amendment and waiver provisions set forth in this paragraph.

Subject to the terms of the Intercreditor Agreement and except as otherwise permitted by the Note Documents, without the consent of the Holders of at least two-thirds in aggregate principal amount of the Notes then outstanding, no amendment or waiver may release from the Liens of this Indenture and the Collateral Documents all or substantially all of the Collateral.

Section 9.03. [Intentionally Omitted].

Section 9.04. Revocation and Effect of Consents.

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

Section 9.05. Notation on or Exchange of Notes.

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

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

Section 9.06. Trustee and Collateral Agent to Sign Amendments, etc.

The Trustee and/or the Collateral Agent, as applicable, shall sign any amended or supplemental indenture authorized pursuant to this Article 9 if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee and/or the Collateral Agent, as applicable. In executing any amended or supplemental indenture, the Trustee and/or the Collateral Agent, as applicable, will be entitled to receive and (subject to Section 7.01 hereof) shall be fully protected in relying upon, in addition to the documents required by Section 13.03 hereof, an Officers’ Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture, and an Opinion of Counsel stating, as and if applicable, that such amended or supplemental indenture will constitute the valid and binding obligation of the Company and the

Guarantors party thereto, enforceable against the Company and such Guarantors in accordance with its terms, subject to customary exceptions.

ARTICLE 10
NOTE GUARANTEES

Section 10.01. Guarantee.

(a) Subject to this Article 10, each of the Guarantors hereby, jointly and severally, fully and unconditionally guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or the obligations of the Company hereunder or thereunder, that:

(1) 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, and all other 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

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

Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors will be jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection.

(b) Subject to this Article 10, the Guarantors hereby agree that their obligations hereunder are unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenant that this Note Guarantee will 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 the Company or the Guarantors, any amount paid by either to the Trustee or such Holder, this Note Guarantee, to the extent theretofore discharged, will be reinstated in full force and effect.

(d) Each Guarantor agrees that it will not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (1) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6 hereof for the purposes of this Note Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (2) in the event of any declaration of acceleration of such obligations as provided in Article 6 hereof, such obligations (whether or not due and payable) will forthwith become due and

payable by the Guarantors for the purpose of this Note Guarantee. The Guarantors will have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Note Guarantee.

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 Note Guarantee of such Guarantor not constitute a fraudulent transfer, fraudulent conveyance or preference for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any Note Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of such Guarantor will be limited to the maximum amount that will, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under this Article 10, result in the obligations of such Guarantor under its Note Guarantee not constituting a fraudulent transfer or conveyance.

Section 10.03. Execution and Delivery of Note Guarantee.

To evidence its Note Guarantee set forth in Section 10.01 hereof, each Guarantor hereby agrees that its execution and delivery of this Indenture or, if applicable, any supplemental indenture pursuant to Section 4.12 hereof and this Section 10.03 shall evidence its Note Guarantee set forth in Section 10.01 hereof without the need for notation on the Notes.

If, after the Issue Date, any Subsidiary of CF Holdings other than the Company becomes a borrower under the Credit Agreement or directly or indirectly guarantees any Indebtedness under the Credit Agreement, if required by Section 4.12 hereof, the Company will cause such Subsidiary to comply with the provisions of Section 4.12 hereof and this Article 10, to the extent applicable.

Section 10.04. Guarantors May Consolidate, etc., on Certain Terms.

No Subsidiary Guarantor may sell or otherwise dispose of all or substantially all of its assets to, or consolidate with or merge with or into (whether or not such Subsidiary Guarantor is the surviving Person) another Person, other than the Company or another Guarantor, unless immediately after giving effect to such transaction, no Default or Event of Default exists.

In case of any such consolidation, merger, sale or conveyance and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the Note Guarantee and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Guarantor, such successor Person will succeed to and be substituted for the Guarantor with the same effect as if it had been named herein as a Guarantor and shall, pursuant to supplements to the Collateral Documents, take such action as may be required to assume the obligations of such Guarantor thereunder, and shall comply with Section 4.15. All the Note Guarantees so issued will in all respects have the same legal rank and benefit under this Indenture as the Note Guarantees theretofore and thereafter evidenced in accordance with the terms of this Indenture as though all of such Note Guarantees had been issued at the date of the execution hereof.

Except as set forth in Articles 4 and 5 hereof, and notwithstanding the first paragraph of this Section 10.04, nothing contained in this Indenture or in any of the Notes will prevent any consolidation or

merger of a Guarantor with or into the Company or another Guarantor, or will prevent any sale or conveyance of the property of a Guarantor as an entirety or substantially as an entirety to the Company or another Guarantor.

Section 10.05. Releases.

Each Subsidiary Guarantor shall be automatically released and relieved of any obligations under its Note Guarantee:

(1) with respect to a particular Subsidiary Guarantor, upon the release, discharge or termination of such Subsidiary Guarantor’s Guarantee of the Credit Agreement Obligations; or

(2) with respect to a particular Subsidiary Guarantor, the consummation of any transaction not prohibited by this Indenture (including by way of sale, disposition or other transfer of Equity Interests of such Subsidiary Guarantor or merger, consolidation, liquidation or dissolution) that results in such Subsidiary Guarantor ceasing to be a Subsidiary of CF Holdings; or

(3) with respect to all subsidiary Guarantors, Legal Defeasance in accordance with Article 8 hereof or satisfaction and discharge of this Indenture in accordance with Article 12 hereof; or

(4) with respect to all Subsidiary Guarantors, upon the latest to occur of the events described in clauses (1), (2), and (3) of Section 10.06(a).

CF Holdings shall be automatically released and relieved of any obligations under its Note Guarantee upon Legal Defeasance in accordance with Article 8 hereof or satisfaction and discharge of this Indenture in accordance with Article 12 hereof.

Any Guarantor not released from its obligations under its Note Guarantee as provided in this Section 10.05 will remain liable for the full amount of principal of and interest and premium, if any, on the Notes and for the other obligations of any Guarantor under this Indenture as provided in this Article 10.

The Company shall notify the Trustee in writing of any Note Guarantee of a Subsidiary Guarantor that is released. The Trustee shall execute and deliver an appropriate instrument confirming the release of any such Subsidiary Guarantor upon the Company’s request and upon being provided an Officers’ Certificate and an Opinion of Counsel to the Trustee stating that all conditions precedent under this Indenture to the execution and delivery of such instrument have been complied with as provided herein.

Section 10.06. Termination of Requirement for Guarantees by Subsidiary Guarantors.

(a) The Note Guarantees shall be automatically released with respect to each Subsidiary Guarantor upon the latest to occur of (1) an Investment Grade Rating Event occurring or having occurred, (2) the retirement, discharge or legal or covenant defeasance of, or satisfaction and discharge of, the supplemental indenture governing, the Company’s 6.875% Senior Notes due 2018 (the “Senior Notes due 2018”) or the Subsidiaries of CF Holdings other than the Company otherwise becoming no longer subject to such a requirement to guarantee the Senior Notes due 2018, and (3) the retirement, discharge or legal or covenant defeasance of, or satisfaction and discharge of, the supplemental indenture governing, the Company’s 7.125% Senior Notes due 2020 (the “Senior Notes due 2020”) or the Subsidiaries of CF

Holdings other than the Company otherwise becoming no longer subject to such a requirement to guarantee the Senior Notes due 2020. Upon and at all times following the release of the Note Guarantees pursuant to this Section 10.06, the first sentence of Section 4.12 hereof shall no longer apply and shall have no further force and effect.

(b) Promptly following an Investment Grade Rating Event, the Company shall deliver an Officers’ Certificate to the Trustee stating that such Investment Grade Rating Event has occurred.

ARTICLE 11
COLLATERAL AND SECURITY

Section 11.01. Collateral Documents.

(a) Prior to an Investment Grade Rating Event, the due and punctual payment of the Notes Obligations, including payment of the principal of, premium on, if any, and interest on, the Notes when and as the same shall be due and payable, whether on an Interest Payment Date, at maturity, by acceleration, repurchase, redemption or otherwise, and interest on the overdue principal of, premium on, if any, and interest on the Notes, according to the terms hereunder or thereunder, are secured as provided in the Collateral Documents which the Company and Guarantors have entered into simultaneously with the execution of this Indenture and will be secured by the Collateral as provided in the Collateral Documents hereafter delivered as required by this Indenture. On the Issue Date, the Company and the Guarantors shall grant a security interest in all their assets constituting Collateral by executing the Security Agreement and such other Collateral Documents that shall be necessary to provide a security interest in the Collateral to the extent required by this Indenture or the Collateral Documents. Notwithstanding the foregoing, in the event that any mortgage on Material Real Property described in clause (i) of the definition thereof is not delivered on the Issue Date, the Company and the Guarantors may provide Mortgages within 120 days after the Issue Date (or such longer period consented to by the Credit Facility Agent in respect of the Credit Agreement Obligations), provided that such date will be automatically extended if the survey requirement may not be performed because of snow ground cover; provided that, with respect to a Material Real Property, the Issuer and the Guarantors shall only be required to comply with the Mortgage requirement in respect of such property if all of the lenders under the Credit Agreement have, to the extent required under the Credit Agreement, provided written notice to the Credit Facility Agent that such lender has completed its due diligence with respect to any applicable flood insurance requirements related to such Material Real Property.

(b) Each Holder, by its acceptance thereof, consents and agrees to the terms of the Collateral Documents (including, without limitation, the provisions providing for possession, use, release and foreclosure of Collateral and the terms of the Intercreditor Agreement) and agrees that it will not contest or support any other person in contesting, in any proceeding (including any insolvency or liquidation proceeding), the perfection, priority, validity or enforceability of a Lien held by or on behalf of any other holder of First-Priority Obligations in all or any part of the Collateral. Each Holder, by its acceptance thereof, (i) authorizes the Trustee to appoint the Collateral Agent to act on its behalf as the Collateral Agent under this Indenture, the Security Agreement and under each of the other Collateral Documents, (ii) authorizes and directs the Collateral Agent to enter into the Collateral Documents and to perform its obligations and exercise its rights thereunder in accordance therewith and (iii) authorizes the Trustee to authorize the Collateral Agent to take such actions on its behalf and to exercise such powers as are delegated to the Collateral Agent by the terms of the Security Agreement and the other Collateral Documents, including for purposes of acquiring, holding and enforcing any and all Liens on Collateral granted by any grantor thereunder to secure any of the First-Priority Obligations, together with such powers and discretion as are reasonably incidental thereto.

(c) Each Holder, by its acceptance thereof, authorizes the Collateral Agent and the Trustee, as applicable, to enter into the Intercreditor Agreement (or, if such agreement is terminated, any substantially identical intercreditor agreement on behalf of, and binding with respect to, the Holders and their interest in designated assets, in connection with the incurrence of any First-Priority Obligations). The Collateral Agent, will enter into any such future intercreditor agreement at the request of the Company, provided that the Company will have delivered to the Collateral Agent, an Officer’s Certificate and Opinion of Counsel to the effect that such other intercreditor agreement is authorized or permitted by this Indenture and the Collateral Documents and that all conditions precedent thereto have been met or waived.

Section 11.02. New Guarantors; After-Acquired Property.

(a) Prior to an Investment Grade Rating Event, with respect to any Person that is or becomes a Guarantor after the Issue Date, the Company shall promptly (and in any event within 45 days (or, in the case of clause (ii) below, 90 days) or in each case such longer period as consented to by the Credit Facility Agent) after the date such Person becomes a Guarantor, cause such Subsidiary (i) to execute a joinder agreement to the applicable Collateral Documents (including the Security Agreement), substantially in the form annexed thereto, (ii) to deliver Mortgages in respect of the Material Real Property owned by such Subsidiary in accordance with the requirements set forth in clause (c) below, and (iii) to take all other actions to cause the Lien created by the applicable Collateral Documents (including the Security Agreement) to be duly perfected within the United States to the extent required by such Collateral Documents. Notwithstanding the foregoing, no Lien or similar interest shall be required to be granted, directly or indirectly, in any Excluded Assets. If requested by the Collateral Agent, the Collateral Agent shall receive an Opinion of Counsel or Opinions of Counsel (which may be from in-house counsel, provided that such opinion is in respect of New York law) for the Company in form and substance reasonably satisfactory to the Collateral Agent in respect of matters reasonably requested by the Collateral Agent relating to any Collateral Document delivered pursuant to this Section 11.02, dated as of the date of such Collateral Document. Notwithstanding anything to the contrary in the Notes or in this Indenture, (i) no Collateral shall be required to be perfected by control other than with respect to Pledged Debt and Pledged Equity (each as defined in the Security Agreement) to the extent required by the terms of the Security Agreement as in effect on the Issue Date, and (ii) no actions in any non-U.S. jurisdiction or required by the laws of any non-U.S. jurisdiction shall be required in order to create any security interests in assets located or titled outside of the U.S. or to perfect such security interests (it being understood that there shall be no security agreements or pledge agreements governed under the laws of any non-U.S. jurisdiction).

(b) Prior to an Investment Grade Rating Event, with respect to any Material Real Property owned by the Company or a Guarantor, the Company or such Guarantor, as applicable, shall no later than 90 days (or such longer period consented to by the Credit Facility Agent) after the later of (x) the date such entity became a Guarantor (if applicable) and (y) the date such Material Real Property is acquired by such entity, execute and deliver (i) counterparts of a Mortgage, duly executed and delivered by the record owner of such property, together with evidence such Mortgage has been duly executed, acknowledged and delivered by a duly authorized officer of each party thereto, in form suitable for filing or recording in all filing or recording offices necessary and, to the extent the Credit Agreement is in effect and secured by Liens on the Collateral, consistent with the filing or recording offices where the Credit Facility Agent makes its filings or recordings for the same properties in order to create a valid and subsisting perfected Lien subject only to Liens permitted under Section 4.09 hereof on the property and/or rights described therein in favor of the Collateral Agent for the benefit of the Holders and the Trustee, and deliver evidence that all filing and recording taxes and fees have been paid or otherwise provided for in a manner reasonably satisfactory to the Collateral Agent (it being understood that if a mortgage tax will be owed on the entire amount of the Indebtedness evidenced hereby, then the amount secured by such Mortgage will

be limited to 100% of the fair market value of the property at the time such Mortgage is entered into if such limitation results in such mortgage tax being calculated based upon such fair market value), (ii) a fully paid policy of title insurance (or marked-up title insurance commitment having the effect of policy of title insurance) on such Mortgaged Property naming the Collateral Agent as the insured for its benefit and that of the Holders and the Trustee (a “Mortgage Policy”) issued by a nationally recognized title insurance company reasonably acceptable to the Collateral Agent in form and substance and in an amount reasonably acceptable to the Collateral Agent (not to exceed 100% of the fair market value of the real properties covered thereby), insuring the Mortgages to be valid subsisting first priority Liens on the property described therein, free and clear of all Liens other than Liens permitted under Section 4.09 hereof and other Liens reasonably acceptable to the Collateral Agent, each of which shall (A) contain a “tie-in” or “cluster” endorsement, if available in the applicable jurisdiction at commercially reasonable rates (i.e., policies which insure against losses regardless of location or allocated value of the insured property up to a stated maximum coverage amount), and (B) have been supplemented by such endorsements as shall be reasonably requested by the Collateral Agent (including endorsements on matters relating to usury, first loss, last dollar, zoning, contiguity, doing business, public road access, variable rate, environmental lien, subdivision, mortgage recording tax, separate tax lot, revolving credit, same as survey and so-called comprehensive coverage over covenants and restrictions, to the extent such endorsements are available in the applicable jurisdiction at commercially reasonable rates), (iii) a survey (which may take the form of an aerial survey, ExpressMap or equivalent photographic depiction) in form and substance sufficient to obtain the Mortgage Policy without the standard survey exception and otherwise reasonably satisfactory to the Collateral Agent, (iv) an opinion of local counsel of the Company or such Guarantor, as applicable, in the state in which such Mortgaged Property is located, with respect to the enforceability and perfection of such Mortgage and any related fixture filings, in form and substance reasonably satisfactory to the Collateral Agent, and (v) to the extent not previously delivered, a completed “life of the loan” Federal Emergency Management Agency Standard Flood Hazard Determination with respect to such Mortgaged Property on which any “building” (as defined in the Flood Insurance Laws), is located, and if such property is in a special flood hazard area, duly executed and acknowledged by the Company or such Guarantor, as applicable, together with evidence of flood insurance in compliance with the Flood Insurance Laws and National Flood Insurance Program as set forth in the Flood Disaster Protection Act of 1973, as amended from time to time, and annual renewals of each flood insurance policy or annual renewals of each force-placed insurance policy, as applicable. Notwithstanding the foregoing, the Company and the Guarantors shall only be required to comply with the requirement to provide a Mortgage with respect to any particular Material Real Property if all of the lenders under the Credit Agreement have, to the extent required under the Credit Agreement, provided written notice to the Credit Facility Agent that such lender has completed its due diligence with respect to any applicable flood insurance requirements related to such Material Real Property. The time period for complying with such Mortgage requirement shall automatically extend to match any additional periods permitted for compliance with the Mortgage requirements under the Credit Agreement.

(c) Notwithstanding the foregoing provisions of this section or anything in this Indenture to the contrary, Liens required to be granted from time to time pursuant to this Section 11.02 shall be subject to exceptions and limitations set forth herein, in the Collateral Documents and to such exceptions as are customary in the applicable jurisdiction (as determined by the Company), which exceptions are also applicable to the comparable Collateral Document executed and delivered in connection with obligations under the Credit Agreement.

Section 11.03. Collateral Agent.

(a) The Trustee hereby appoints the Collateral Agent to act on its behalf under this Indenture and each Collateral Document, and the Collateral Agent agrees to act as such; provided that, it is

understood and agreed that all communications between the Collateral Agent and the Holders and all instructions or directions by Holders to the Collateral Agent shall be made or given through the Trustee.

(b) The Trustee hereby appoints Wells Fargo Bank, National Association to act on its behalf as the Collateral Agent under this Indenture, the Security Agreement and under each of the other Collateral Documents and to exercise such powers and perform such duties as are expressly delegated to the Collateral Agent by the terms of this Indenture and the Collateral Documents, and Wells Fargo Bank, National Association agrees to act as such. The provisions of this Section 11.03 are solely for the benefit of the Collateral Agent and none of the Trustee, any of the Holders shall have any rights as a third party beneficiary of any of the provisions contained herein. Each Holder agrees that any action taken by the Collateral Agent in accordance with the provisions of this Indenture and the Collateral Documents, and the exercise by the Collateral Agent of any rights or remedies set forth herein and therein shall be authorized and binding upon all Holders. Notwithstanding any provision to the contrary contained elsewhere in this Indenture and the Collateral Documents, the duties of the Collateral Agent shall be ministerial and administrative in nature, and the Collateral Agent shall not have any duties or responsibilities, except those expressly set forth herein and in the Collateral Documents to which the Collateral Agent is a party, nor shall the Collateral Agent have or be deemed to have any trust or fiduciary relationship with the Trustee, any Holder or any Guarantor, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Indenture and the Collateral Documents or otherwise exist against the Collateral Agent. Without limiting the generality of the foregoing sentence, the use of the term “agent” in this Indenture with reference to the Collateral Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law. Instead, such term is used merely as a matter of market custom, and is intended to create or reflect only an administrative relationship between independent contracting parties.

(c) Subject to the provisions of the Collateral Documents, each Holder, by acceptance of the Notes, agrees that the Collateral Agent shall execute and deliver the Collateral Documents to which it is a party and all agreements, power of attorney, documents and instruments incidental thereto, and act in accordance with the terms thereof.

(d) The Collateral Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default, unless the Collateral Agent shall have received written notice from the Trustee or unless a written notice of any event which is in fact such a Default is received by the Collateral Agent at the address specified in Section 13.01, and such notice references the Notes and this Indenture. Subject to the Intercreditor Agreement, the Collateral Agent shall take such action with respect to such Default or Event of Default as may be requested by the Trustee in accordance with Article 6 or the Holders of a majority in aggregate principal amount of the Notes (subject to this Section 11.03).

(e) If at any time or times the Trustee shall receive (i) by payment, foreclosure, set-off or otherwise, any proceeds of Collateral, except for any such proceeds or payments received by the Trustee from the Collateral Agent pursuant to the terms of this Indenture, or (ii) payments from the Collateral Agent in excess of the amount required to be paid to the Trustee pursuant to Article 6, the Trustee shall promptly turn the same over to the Collateral Agent, in kind, and with such endorsements as may be required to negotiate the same to the Collateral Agent such proceeds to be applied by the Collateral Agent pursuant to the terms of this Indenture and the Intercreditor Agreement.

(f) The Collateral Agent shall have no obligation whatsoever to the Trustee or any of the Holders to assure that the Collateral exists or is owned by the Company or any Guarantor or is cared for, protected, or insured or has been encumbered, or that the Collateral Agent’s Liens have been properly or sufficiently or lawfully created, perfected, protected, maintained or enforced or are entitled to any particular priority, or to determine whether all of the Company’s or any Guarantor’s property constituting

Collateral has been properly and completely listed or delivered, as the case may be, or the genuineness, validity, marketability or sufficiency thereof or title thereto, or to exercise at all or in any particular manner or under any duty of care, disclosure, or fidelity, or to continue exercising, any of the rights, authorities, and powers granted or available to the Collateral Agent pursuant to this Indenture or any other Collateral Documents, it being understood and agreed that in respect of the Collateral, or any act, omission, or event related thereto, the Collateral Agent shall have no other duty or liability whatsoever to the Trustee or any Holder as to any of the foregoing.

(g) The Collateral Agent may resign at any time by notice to the Trustee and the Company, such resignation to be effective upon the acceptance of a successor agent to its appointment as Collateral Agent. If the Collateral Agent resigns under this Indenture, the Company shall appoint a successor collateral agent. If no successor collateral agent is appointed prior to the intended effective date of the resignation of the Collateral Agent (as stated in the notice of resignation), the Collateral Agent may appoint, after consulting with the Trustee, subject to the consent of the Company (which shall not be unreasonably withheld and which shall not be required during a continuing Event of Default), a successor collateral agent. If no successor collateral agent is appointed and consented to by the Company pursuant to the preceding sentence within thirty (30) days after the intended effective date of resignation (as stated in the notice of resignation) the Collateral Agent shall be entitled to petition a court of competent jurisdiction to appoint a successor. Upon the acceptance of its appointment as successor collateral agent hereunder, such successor collateral agent shall succeed to all the rights, powers and duties of the retiring Collateral Agent, and the term “Collateral Agent” shall mean such successor collateral agent, and the retiring Collateral Agent’s appointment, powers and duties as the Collateral Agent shall be terminated. Promptly following the acceptance of the appointment of any successor Collateral Agent, the Company shall cause assignments of filings existing on the date of such assignment related to the Collateral to be filed or recorded sufficient to reflect the successor Collateral Agent, as mortgagee or secured party of record in accordance with applicable law related to each portion of the Collateral. After the retiring Collateral Agent’s resignation hereunder, the provisions of this Section 11.03 (and Article 6) shall continue to inure to its benefit and the retiring Collateral Agent shall not by reason of such resignation be deemed to be released from liability as to any actions taken or omitted to be taken by it while it was the Collateral Agent under this Indenture. The Collateral Agent shall not be liable or responsible for the failure of the Company or any Guarantors to maintain insurance on the Collateral, nor shall it be responsible for any loss due to the insufficiency of such insurance or by reason of the failure of any insurer to pay the full amount of any loss against which it may have insured to the Company, the Guarantors, the Trustee, the Collateral Agent or any other Person.

(h) Notwithstanding anything to the contrary in this Indenture or any Collateral Document, in no event shall the Collateral Agent or the Trustee be responsible for, or have any duty or obligation with respect to, the recording, filing, registering, perfection, protection or maintenance of the security interests or Liens intended to be created by this Indenture or the Collateral Documents (including without limitation the filing or continuation of any UCC financing statements, mortgages, security agreements, or similar documents or instruments in any U.S. or foreign jurisdiction ), nor shall the Collateral Agent or the Trustee be responsible for, and neither the Collateral Agent nor the Trustee makes any representation regarding, the validity, effectiveness or priority of any of the Collateral Documents or the security interests or Liens intended to be created thereby.

(i) The provisions of Article 7, mutatis mutandis, shall apply to the Collateral Agent.

Section 11.04. Release of Liens.

(a) The Collateral shall be released from the Liens and security interest created by the Collateral Documents to secure the Notes Obligations, all without delivery of any instrument or

performance of any act by any party, at any time or from time to time as provided by this Section 11.04. Upon such release, subject to the terms of the Collateral Documents all rights in the Collateral securing the Notes Obligations shall revert to the Company and the Guarantors.

(b) The Liens on the Collateral owned by any Guarantor and securing the Notes will be automatically released when the Note Guarantee of such Guarantor is released in accordance with the terms of this Indenture.

(1) in whole, pursuant to Section 11.07;

(2) in whole or in part as provided in the Intercreditor Agreement;

(3) in whole or in part, with the consent of the requisite Holders of the Notes in accordance with the provisions of Article 9;

(4) as to any asset constituting Collateral that is sold or otherwise disposed of or transferred by the Company or any of the Guarantors to any Person that is not the Company or a Guarantor in a transaction not prohibited by this Indenture (to the extent of the interest sold or disposed of or transferred);

(5) as to any asset constituting Collateral that is Capital Stock, upon the dissolution, liquidation, consolidation or similar transaction in respect of the issuer of that Capital Stock that is not prohibited by this Indenture;

(6) as to any asset constituting Collateral that becomes an Excluded Asset pursuant to a transaction not prohibited by this Indenture; and

(7) in whole, upon an Investment Grade Rating Event as described under Section 11.10(a) subject to no Default or Event of Default having occurred and then continuing.

(d) Upon the Company’s request, the Collateral Agent shall, at the Company’s expense, execute and deliver to the Company any documents, financing statements, agreements, instruments or certificates requested and prepared by the Company to evidence the release of Collateral following the Collateral Agent’s receipt of an Officers’ Certificate and an Opinion of Counsel certifying that such release of Collateral complies with the terms of this Indenture. Neither the Trustee nor the Collateral Agent shall be liable for any such release undertaken in good faith and that it believes to be authorized or within the rights or powers conferred upon it by this Indenture and the Collateral Documents.

(e) Liens securing the Notes and the related Note Guarantees may be subordinated promptly upon the Company’s request and upon receipt by the Collateral Agent of an Officers’ Certificate and an Opinion of Counsel certifying that such subordination of Collateral is in accordance with the terms of this Indenture on any property subject or to be subject to a Lien to the extent that such Liens are not prohibited under the Note Documents and the other documents governing the then outstanding First-Priority Lien Obligations; provided that no such subordination shall be required unless the Liens securing the other First-Priority Lien Obligations are also subordinated to the same extent as the Liens securing the Notes.

(f) The release of any Collateral from the terms of this Indenture and the Collateral Documents will not be deemed to impair the security under this Indenture in contravention of the

provisions hereof if and to the extent the Collateral is released pursuant to the terms of the Collateral Documents.

Section 11.05. Authorization of Actions to be Taken by the Trustee Under the Collateral Documents.

Subject to the provisions of the Collateral Documents, the Trustee may direct, on behalf of Holders of the Notes, the Collateral Agent to take action permitted to be taken by it under the Collateral Documents.

Upon the occurrence and during the continuation of an Event of Default and subject to the provisions of the Security Agreement, and subject to the provisions of Section 7.01 and Section 7.02, the Trustee may, in its sole discretion and without the consent of the Holders, direct, on behalf of the Holders, the Collateral Agent to take all actions it deems necessary or appropriate in order to:

(a) enforce any of the terms of the Collateral Documents; and

(b) collect and receive any and all amounts payable in respect of the Notes Obligations of the Company hereunder.

Subject to the provisions of the Security Agreement and the other Collateral Documents, the Trustee and the Collateral Agent will have power to institute and maintain such suits and proceedings, at the expense of the Company, as it may deem expedient to prevent any impairment of the Collateral by any acts that may be unlawful or in violation of the Collateral Documents or this Indenture, and such suits and proceedings as the Trustee or the Collateral Agent may deem expedient to preserve or protect its interests and the interests of the Holders in the Collateral (including power to institute and maintain suits or proceedings to restrain the enforcement of or compliance with any legislative or other governmental enactment, rule or order that may be unconstitutional or otherwise invalid if the enforcement of, or compliance with, such enactment, rule or order would impair the security interest hereunder or be prejudicial to the interests of the Holders or of the Trustee or the Collateral Agent). Nothing in this Section 11.05 shall be considered to impose any such duty or obligation to act on the part of the Trustee or the Collateral Agent.

Section 11.06. Authorization of Receipt of Funds by the Collateral Agent Under the Collateral Documents.

Subject to the provisions of the Security Agreement, the Collateral Agent is authorized to receive any funds for the benefit of the Holders distributed under the Collateral Documents, and to make further distributions of such funds to the Trustee for further distribution to the Holders according to the provisions of this Indenture.

Section 11.07. Termination of Security Interest.

Upon the full and final payment and performance of all Notes Obligations of the Company under this Indenture and the Notes or upon Legal Defeasance, Covenant Defeasance or satisfaction and discharge of this Indenture in accordance with Article 8 and Article 12 hereof, the Trustee (or the Collateral Agent on its behalf) will, at the request of the Company, deliver a certificate to the Collateral Agent stating that such Notes Obligations have been paid in full, and instruct the Collateral Agent to, as applicable, either (a) release the Liens securing the Notes Obligations pursuant to this Indenture and the Collateral Documents or (b) cease to be a party to the Collateral Documents on behalf of the Trustee and the Holders.

Section 11.08. Purchaser Protected.

In no event shall any purchaser or other transferee in good faith of any property or assets purported to be released hereunder be bound to ascertain the authority of the Collateral Agent or the Trustee to execute the release or to inquire as to the satisfaction of any conditions required by the provisions hereof for the exercise of such authority or to see to the application of any consideration given by such purchaser or other transferee; nor shall any purchaser or other transferee of any property or assets be under any obligation to ascertain or inquire into the authority of the Company or the applicable Guarantor to make any such sale or other transfer.

Section 11.09. Powers Exercisable by Receiver or Trustee.

In case the Collateral shall be in the possession of a receiver or trustee, lawfully appointed, the powers conferred in this Article 11 upon the Company or a Guarantor with respect to the release, sale or other disposition of such property or assets may be exercised by such receiver or trustee, and an instrument signed by such receiver or trustee shall be deemed the equivalent of any similar instrument of the Company or a Guarantor or of any officer or officers thereof required by the provisions of this Article 11; and if the Trustee shall be in the possession of the Collateral under any provision of this Indenture, then such powers may be exercised by the Trustee.

Section 11.10. Termination of Requirement for Collateral.

(a) If on any date following the Issue Date (i) the Investment Grade Rating Condition is satisfied and (ii) no Default or Event of Default has occurred and is then continuing (the occurrence of the events described in the foregoing clauses (i) and (ii) being collectively referred to as an “Investment Grade Rating Event”), then (1) on that date, the Liens on the Collateral securing the Notes and the Notes Obligations will be automatically released and the Collateral Documents will be automatically terminated and (2) on and after that date, CF Holdings and its Subsidiaries will not be subject to Section 4.07 hereof or this Article 11.

ARTICLE 12
SATISFACTION AND DISCHARGE

(2) all Notes that have not been delivered to the Trustee for cancellation (A) have become due and payable, (B) will become due and payable at their Stated Maturity within one year or (C) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption and, in the case of the provisions described in (A), (B) or (C), as applicable, of this clause (2), the Company or any Guarantor has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders, cash in U.S. dollars, Government Securities, or a combination of cash in U.S. dollars and Government Securities, in amounts as will be sufficient, in the opinion of a nationally recognized investment bank, appraisal firm or firm of independent public accountants if Government Securities are delivered, without consideration of any reinvestment of interest, to pay and discharge the entire Indebtedness on the Notes not delivered to the Trustee for cancellation for principal, premium, if any, and accrued interest to the date of maturity or redemption;

(b) no Default or Event of Default shall have occurred and be continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit), and the deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which the Company or any Guarantor is a party or by which the Company or any Guarantor is bound;

(c) the Company or any Guarantor has paid or caused to be paid all sums payable by it under this Indenture with respect to the Notes; and

(d) the Company has delivered irrevocable instructions to the Trustee under this Indenture with respect to the Notes to apply the deposited money toward the payment of the Notes at maturity or on the applicable redemption date, as the case may be.

In addition, the Company must deliver an Officers’ Certificate and an Opinion of Counsel to the Trustee stating that all conditions precedent relating to satisfaction and discharge of this Indenture have been complied with. Promptly following the payment in full of all outstanding Notes and other amounts payable pursuant to the Note Documents, the Company and the Guarantors, at their expense, shall prepare and deliver to the Trustee or Collateral Agent, as applicable, for execution, appropriate instruments causing the lien and security interests related to the Collateral to be released. Upon receipt of such executed instruments from the Trustee or Collateral Agent, as applicable, the Company shall file and record such instruments.

Notwithstanding the satisfaction and discharge of this Indenture, if money has been deposited with the Trustee pursuant to subclause (2) of clause (a) of this Section 12.01, the provisions of this Section 12.01 and of Sections 12.02 and 8.06 hereof will survive. In addition, nothing in this Section 12.01 will be deemed to discharge those provisions of Section 7.07 hereof, that, by their terms, survive the satisfaction and discharge of this Indenture.

Section 12.02. Application of Trust Money.

Subject to the provisions of Section 8.06 hereof, all money deposited with the Trustee pursuant to Section 12.01 hereof shall be held in trust and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the

The Company, any Guarantor, the Trustee or the Collateral Agent, by notice to the others, may designate additional or different addresses and/or facsimile numbers for subsequent notices or communications. The Trustee and the Collateral Agent shall have the right, but shall not be required, to rely upon and comply with instructions and directions sent by e-mail, facsimile and other similar unsecured electronic methods by persons reasonably believed in good faith by the Trustee or the Collateral Agent to be authorized to give instructions and directions on behalf of the Company, the Guarantors or any Person. The Trustee or the Collateral Agent shall have no duty or obligation to verify or confirm that the Person who sent such instructions or directions is, in fact, a Person authorized to give instructions or directions on behalf of the Company or Guarantors; and the Trustee or the Collateral Agent shall have no liability for any losses, liabilities, costs or expenses incurred or sustained by the Company or Guarantors as a result of such reliance upon or compliance with such instructions or directions. The Company or Guarantors agree to assume all risks arising out of the use of such electronic methods to submit instructions and directions to the Trustee or the Collateral Agent, including, without limitation, the risk of the Trustee or the Collateral Agent acting on unauthorized instructions, and the risk of interception and misuse by third parties.

All notices and communications (other than those sent to Holders) will be deemed to have been duly given: at the time delivered by hand, if personally delivered; three Business Days after being deposited in the mail, postage prepaid, if mailed by first class mail (certified or registered, return receipt requested); upon acknowledgment of receipt, if transmitted by facsimile; and the next Business Day after timely delivery to the courier, if sent by overnight air courier guaranteeing next-day delivery.

Any notice or communication to a Holder shall be mailed by first class mail, certified or registered, return receipt requested, or sent by overnight air courier guaranteeing next day delivery to its address shown on the register kept by the Registrar or, with respect to Global Notes, to the extent permitted or required by applicable DTC procedures or regulations, sent electronically. Failure to deliver, mail, transmit or send a notice or communication to a Holder or any defect in it will not affect its sufficiency with respect to other Holders.

If a notice or communication is delivered, mailed, transmitted or sent in the manner provided above within the time prescribed, it is duly given, whether or not the addressee receives it.

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

Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance on such waiver.

In case it shall be impracticable to give notice in the manner provided above, including by reason of a suspension of regular mail service, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder.

Section 13.02. [Intentionally Omitted].

Section 13.03. Certificate and Opinion as to Conditions Precedent.

Upon any request or application by the Company to the Trustee to take any action under this Indenture, the Company shall furnish to the Trustee:

Each Holder of the Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. Such waiver and release may not be effective to waive liabilities under the U.S. federal securities laws.

Section 13.07. Governing Law; Jury Trial Waiver.

THE INTERNAL LAW OF THE STATE OF NEW YORK WILL GOVERN AND BE USED TO CONSTRUE THIS INDENTURE, THE NOTES AND THE NOTE GUARANTEES WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

EACH PARTY HERETO, AND EACH HOLDER OF A NOTE BY ACCEPTANCE THEREOF, HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS INDENTURE.

All agreements of the Company in this Indenture and the Notes will bind its successors. All agreements of the Trustee in this Indenture will bind its successors. All agreements of each Guarantor in this Indenture will bind its successors, except as otherwise provided in Section 10.05 hereof.

Section 13.10. Severability.

In case any provision in this Indenture or in the Notes is invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions will not in any way be affected or impaired thereby, and such provision shall be ineffective only to the extent of such invalidity, illegality or unenforceability.

The parties may sign any number of copies of this Indenture. Each signed copy will be an original, but all of them together represent the same agreement. The exchange of copies of this Indenture and of signature pages by facsimile or PDF transmission shall constitute effective execution and delivery of this Indenture as to the parties hereto. Signatures of the parties hereto transmitted by facsimile or PDF shall be deemed to be their original signatures for all purposes.

Section 13.12. Table of Contents, Headings, etc.

The Table of Contents and Headings of the Articles and Sections of this Indenture have been inserted for convenience of reference only, are not to be considered a part of this Indenture and will in no way modify or restrict any of the terms or provisions of this Indenture.

Section 13.13. Legal Holidays.

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

The Company will pay interest, if any, semi-annually in arrears on June 1 and December 1 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest Payment Date”). Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance; provided that if there is no existing Default in the payment of interest, and if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date; provided, further, that the first Interest Payment Date shall be , 20 . The Company will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium, if any, from time to time on demand at the rate equal to the then applicable interest rate on the Notes to the extent lawful; it will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest, if any (without regard to any applicable grace periods) from time to time on demand at the same rate to the extent lawful. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

(2) METHOD OF PAYMENT. The Company will pay interest on the Notes (except defaulted interest), to the Persons who are registered Holders of Notes at the close of business on the May 15 and November 15 next preceding the Interest Payment Date, even if such Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in Section 2.13 of the Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium, if any, and interest at the office or agency of the Company maintained for such purpose or, at the option of the Company, payment of interest, if any, may be made by check mailed to the Holders at their addresses set forth in the register of Holders; provided that payment by wire transfer of immediately available funds will be required with respect to principal of and interest and premium on, all Global Notes and all other Notes the Holders of which will have provided wire transfer instructions to the Company or the Paying Agent; provided, further, that the Company will pay all principal, interest and premium, if any, on any Global Notes registered in the name of DTC or its nominee in immediately available funds to DTC or such nominee, as the case may be, as the registered holder of such Global Notes. Such payment will be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. If a payment date is a Legal Holiday, payment shall be made on the next succeeding day that is not a Legal Holiday, and no interest shall accrue for the intervening period on any amount that would otherwise have been payable on such payment date if it were not a Legal Holiday. If a regular record date is a Legal Holiday, the record date shall not be affected.

(3) PAYING AGENT AND REGISTRAR. Initially, Wells Fargo Bank, National Association, the Trustee, will act as Paying Agent and Registrar. The Company may change any

A-5

Paying Agent or Registrar without notice to any Holder. The Company or any of its Subsidiaries may act in any such capacity.

(4) INDENTURE. The Company issued the Notes under an indenture, dated as of November 21, 2016 (the “Indenture”), among the Company, the Guarantors, the Trustee and the Collateral Agent. The terms of the Notes include those stated in the Indenture. The Notes are subject to all such terms, and Holders are referred to the Indenture for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. The Indenture does not limit the aggregate principal amount of Notes that may be issued thereunder.

(5) OPTIONAL REDEMPTION. The Company may redeem the Notes, in whole at any time or in part from time to time, at its option, at a redemption price equal to the greater of:

(a) 100% of the principal amount of the Notes to be redeemed; and

(b) as determined by the Quotation Agent, the sum of the present values of the remaining scheduled payments of principal and interest on the Notes being redeemed (excluding any portion of such payments of interest accrued as of the applicable redemption date), discounted to the applicable redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate, plus 30 basis points;

plus, in each case, accrued and unpaid interest, if any, thereon to, but not including, the applicable redemption date.

Notwithstanding the foregoing, installments of interest on Notes that are due and payable on interest payment dates falling on or prior to a redemption date will be payable on the interest payment date to the Holders as of the close of business on the relevant record date.

(6) MANDATORY REDEMPTION. The Company is not required to make mandatory redemption or sinking fund payments with respect to the Notes.

(7) OFFER TO REPURCHASE UPON CHANGE OF CONTROL REPURCHASE EVENT. If a Change of Control Repurchase Event occurs, unless the Company has exercised its right to redeem the Notes pursuant to Section 3.07 of the Indenture, the Company will make an offer (a “Change of Control Offer”) to each Holder to repurchase all or any part (equal to $2,000 or integral multiples of $1,000 in excess of $2,000) of that Holder’s Notes at a purchase price in cash equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest, if any, on the Notes repurchased to, but not including, the date of repurchase. Notwithstanding the foregoing, installments of interest on Notes that are due and payable on interest payment dates falling on or prior to a Change of Control Payment Date will be payable on the interest payment date to the Holders as of the close of business on the relevant record date. Within 30 days following any Change of Control Repurchase Event, the Company shall mail (or with respect to Global Notes, to the extent permitted or required by applicable DTC procedures or regulations, send electronically) a notice to each Holder setting forth the procedures governing the Change of Control Offer as required by the Indenture.

(8) NOTICE OF REDEMPTION. Notice of redemption will be mailed (or with respect to Global Notes, to the extent permitted or required by applicable DTC procedures or regulations, sent electronically) at least 30 days but not more than 60 days before the redemption date to each

A-6

Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be mailed or sent more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction or discharge of the Indenture. Subject to the Company’s compliance with the first paragraph of Section 3.05 of the Indenture, interest on the Notes or the portions of Notes called for redemption ceases to accrue on and after the redemption date.

(9) PERSONS DEEMED OWNERS. The registered Holder of a Note may be treated as its owner for all purposes.

(10) AMENDMENT, SUPPLEMENT AND WAIVER. The Note Documents may be amended or supplemented as provided in Article 9 of the Indenture.

(11) DEFAULTS AND REMEDIES. If an Event of Default (as defined in the Indenture), other than an Event of Default resulting from any failure by CF Holdings or the Company to comply with Section 4.03 of the Indenture, occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the Notes may declare all the Notes to be due and payable. If a bankruptcy or insolvency default with respect to CF Holdings or any of its Subsidiaries that is a Significant Subsidiary of CF Holdings or any group of Subsidiaries that, taken together, would constitute a Significant Subsidiary of CF Holdings, occurs and is continuing, all outstanding Notes will become due and payable immediately without further action or notice. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee may require indemnity satisfactory to it before it enforces the Indenture or the Notes. Subject to certain limitations, Holders of a majority in principal amount of the Notes then outstanding may direct the Trustee in its exercise of remedies.

(12) TRUSTEE DEALINGS WITH COMPANY. The Trustee, in its individual capacity or any other capacity, may make loans to, accept deposits from, and perform service for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not the Trustee. Any Agent may do the same with like rights and duties. The Trustee is also subject to and entitled to the benefits of Article 7 of the Indenture with respect to the Notes.

(13) NO RECOURSE AGAINST OTHERS. No director, officer, employee, incorporator or stockholder of CF Holdings, and no director, officer, employee, incorporator, member or stockholder of any Subsidiary of CF Holdings, as such, will have any liability for any obligations of the Company or any Guarantor under any Note Document or the Indenture or for any claim based on, in respect of, or by reason of such obligations or their creation. Each Holder of the Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. Such waiver and release may not be effective to waive liabilities under the U.S. federal securities laws.

(14) AUTHENTICATION. This Note will not be valid until authenticated by the manual signature of the Trustee or an authenticating agent.

(15) COLLATERAL. The Notes are secured by a security interest in the Collateral, subject to the terms of the Collateral Documents, the Intercreditor Agreement and any other applicable intercreditor agreement, subject to release or termination as provided in the Indenture, the Intercreditor Agreement and the Collateral Documents.

(16) GUARANTEES. This Note is guaranteed as set forth in the Indenture.
