BY ITS ACQUISITION HEREOF OR OF A BENEFICIAL INTEREST HEREIN, THE HOLDER:

(1) REPRESENTS THAT (A) IT IS A “QUALIFIED INSTITUTIONAL BUYER” (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) (A “QIB”) OR (B) IT IS ACQUIRING THIS SECURITY IN AN OFFSHORE TRANSACTION IN COMPLIANCE WITH REGULATION S UNDER THE SECURITIES ACT;

(3) AGREES THAT IT WILL DELIVER TO EACH PERSON TO WHOM THIS SECURITY OR AN INTEREST HEREIN IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND.

AS USED HEREIN, THE TERMS “OFFSHORE TRANSACTION” AND “UNITED STATES” HAVE THE MEANINGS GIVEN TO THEM BY RULE 902 OF REGULATION S UNDER THE SECURITIES ACT. THE INDENTURE GOVERNING THIS SECURITY CONTAINS A PROVISION REQUIRING THE TRUSTEE TO REFUSE TO REGISTER ANY TRANSFER OF THIS SECURITY IN VIOLATION OF THE FOREGOING.”

(B) Notwithstanding the foregoing, any Global Note or Definitive Note issued pursuant to clause (b)(iv), (c)(ii), (c)(iii), (d)(ii), (d)(iii), (e)(ii), (e)(iii) or (f) to this Section 2.06 (and all Notes issued in exchange therefor or substitution thereof) shall not bear the Private Placement Legend.

“THIS GLOBAL NOTE IS HELD BY THE DEPOSITARY (AS DEFINED IN THE INDENTURE GOVERNING THIS NOTE) OR ITS NOMINEE IN CUSTODY FOR THE BENEFIT OF THE BENEFICIAL OWNERS HEREOF, AND IS NOT TRANSFERABLE TO ANY PERSON UNDER ANY CIRCUMSTANCES EXCEPT THAT (I) THE TRUSTEE MAY MAKE SUCH NOTATIONS HEREON AS MAY BE REQUIRED PURSUANT TO SECTION 2.06 OF THE INDENTURE, (II) THIS GLOBAL NOTE MAY BE EXCHANGED IN WHOLE BUT NOT IN PART PURSUANT TO SECTION 2.06(a) OF THE INDENTURE, (III) THIS GLOBAL NOTE MAY BE DELIVERED TO THE TRUSTEE FOR CANCELLATION PURSUANT TO SECTION 2.11 OF THE INDENTURE AND (IV) THIS GLOBAL NOTE MAY BE TRANSFERRED TO A SUCCESSOR DEPOSITARY WITH THE PRIOR WRITTEN CONSENT OF THE ISSUER.

SUCCESSOR DEPOSITARY. UNLESS THIS NOTE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION (“DTC”), TO THE ISSUER OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY NOTE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS MAY BE REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS MAY BE REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.”

“THIS SECURITY IS A REGULATION S TEMPORARY GLOBAL NOTE WITHIN THE MEANING OF THE INDENTURE REFERRED TO HEREINAFTER AND IS SUBJECT TO THE RESTRICTIONS ON THE TRANSFER AND EXCHANGE HEREOF AS SPECIFIED IN THE INDENTURE. UNTIL 40 DAYS AFTER THE ISSUE DATE HEREOF, AN OFFER OR SALE OF THE NOTES WITHIN THE UNITED STATES BY A DEALER (AS DEFINED IN THE SECURITIES ACT OF 1933, AS AMENDED) MAY VIOLATE THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT OF 1933, AS AMENDED, IF SUCH OFFER OR SALE IS MADE OTHERWISE THAN IN ACCORDANCE WITH RULE 144A UNDER THE SECURITIES ACT OF 1933, AS AMENDED.”

(h) Cancellation and/or Adjustment of Global Notes . At such time as all beneficial interests in a particular Global Note have been exchanged for Definitive Notes of such series or a particular Global Note has been redeemed, repurchased or cancelled in whole and not in part, each such Global Note shall be returned to or retained and cancelled by the Trustee in accordance with Section 2.11 hereof. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note of such series or for Definitive Notes of such series, the aggregate principal amount of Notes represented by such Global Note shall be reduced accordingly and an endorsement shall be made on such Global Note by the Trustee or by the Custodian at the direction of the Trustee to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note of the same series, the aggregate principal amount of such other Global Note shall be increased accordingly and an endorsement shall be made on such Global Note by the Trustee or by the Custodian at the direction of the Trustee to reflect such increase.

35

Section 2.07. Replacement Notes .

If any mutilated Note of any series is surrendered to the Trustee or the Issuer and the Trustee receives evidence to its satisfaction of the destruction, loss or theft of such Note, the

36

Issuer shall issue and, upon receipt of an Authentication Order in accordance with Section 2.02 hereof, the Trustee shall authenticate a replacement Note of the same series. If required by the Trustee or the Issuer, the Holder of such Note shall provide indemnity that is sufficient, in the judgment of the Trustee or the Issuer, to protect the Issuer, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer in connection with such replacement. If required by the Issuer, such Holder shall reimburse the Issuer for its reasonable expenses in connection with such replacement.

Every replacement Note issued in accordance with this Section 2.07 shall be the valid obligation of the Issuer, evidencing the same Indebtedness as the destroyed, lost or stolen Note, and shall be entitled to all of the benefits of this Indenture equally and proportionately with all other Notes of the same series duly issued hereunder.

Section 2.08. Outstanding Notes .

(a) The Notes of any series outstanding at any time shall be the entire principal amount of Notes represented by all of the Global Notes of such series and Definitive Notes of such series authenticated by the Trustee except for those cancelled by the Trustee, those delivered to the Trustee for cancellation, those subject to reductions in beneficial interests effected by the Trustee in accordance with Section 2.06 hereof, and those described in this Section 2.08 as not outstanding. Except as set forth in Section 2.09 hereof, a Note shall not cease to be outstanding because the Issuer or an Affiliate of the Issuer holds the Note.

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

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

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

(e) Notes as to which defeasance has been effected pursuant to Article 8 shall not be considered Outstanding.

In determining whether the Holders of the required principal amount of Notes of any series have concurred in any direction, waiver or consent, Notes of such series owned by the Issuer, or by any Affiliate of the Issuer, shall not be considered to be outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes of such series that a Responsible Officer of the Trustee actually knows are so owned shall be so disregarded.

37

Section 2.10. Temporary Notes .

Until certificates representing Notes are ready for delivery, the Issuer may prepare and, upon receipt of an Authentication Order in accordance with Section 2.02 hereof, the Trustee shall authenticate temporary Notes (each a “ Temporary Note ”). Temporary Notes shall be substantially in the form of Definitive Notes but may have variations that the Issuer considers appropriate for temporary Notes and as shall be reasonably acceptable to the Trustee. Without unreasonable delay, the Issuer shall prepare and the Trustee shall authenticate Global Notes or Definitive Notes in exchange for Temporary Notes, as applicable. After preparation of Definitive Notes, the Temporary Note will be exchangeable for Definitive Notes upon surrender of the Temporary Notes.

Holders of Temporary Notes of any series shall be entitled to all of the benefits of this Indenture equally and proportionately with all other Notes of such series duly issued hereunder.

Section 2.11. Cancellation .

Certification of the disposition of all cancelled Notes shall be delivered to the Issuer from time to time upon request. The Issuer may not issue new Notes to replace Notes that it has paid or, except as expressly permitted by this Indenture, that have been delivered to the Trustee for cancellation.

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

38

however , that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of a redemption or notice of an offer to purchase and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption or offer to purchase shall not be affected by any defect in or omission of such numbers. The Issuer shall promptly notify the Trustee of any change in the “CUSIP”, “ISIN” and/or other similar numbers.

Section 2.14. Special Interest .

From and after the effective time of the Merger, if Special Interest is payable by the Issuer pursuant to the Registration Rights Agreement for any series of Notes, the Issuer shall deliver to the Trustee a certificate to that effect stating (i) the amount of such Special Interest that is payable and (ii) the date on which such interest is payable pursuant to Section 4.01 hereof. Unless and until a Responsible Officer of the Trustee receives such a certificate or instruction or direction from the Holders in accordance with the terms of this Indenture, the Trustee may assume without inquiry that no Special Interest is payable. The foregoing shall not prejudice the rights of the Holders with respect to their entitlement to Special Interest as otherwise set forth in this Indenture or the Notes and pursuing any action against the Issuer directly or otherwise directing the Trustee to take any such action in accordance with the terms of this Indenture and the Notes. If the Issuer has paid Special Interest directly to the Persons entitled to it, the Issuer shall deliver to the Trustee an Officers’ Certificate setting forth the details of such payment.

Section 2.15. Issuance of Additional Notes .

The Issuer shall be entitled to issue additional Notes of any series of Notes issued under this Indenture which shall have identical terms as applicable series of Notes issued on the date hereof, other than with respect to the date of issuance, issue price and rights under the Registration Rights Agreement relating to the applicable series of Notes.

(c) whether such additional Notes shall be subject to the restrictions on transfer set forth in Section 2.06 hereof relating to Restricted Global Notes and Restricted Definitive Notes.

Section 3.03. Special Mandatory Redemption .

In the event that the Merger Agreement is terminated or the Spin-Off and the Merger are not completed on or before October 1, 2010, the Notes of each series will be subject to a special mandatory redemption (the “ Special Mandatory Redemption ”), and in such event, the Trustee, on the date on which it receives notice of the Special Mandatory Redemption from the Escrow Agent (the “ Redemption Notice Date ”), shall promptly notify each Holder (with a copy to the Escrow Agent) that all of the outstanding Notes of each series shall be redeemed on either the (i) the Redemption Notice Date or (ii) the next Business Day following the Redemption Notice Date, in accordance with the terms of the Escrow Agreement (such date, the “ Special Redemption Date ”) automatically and without any further action by the Holders of the Notes, at a redemption price equal to 100% of the issue price of such series of Notes, plus accrued and unpaid interest on the principal amount of such series of Notes to, but not including, the date of redemption (the “Special Mandatory Redemption Price” ) and, promptly upon receipt of such notice, shall forward such notice to the Paying Agent. Upon receipt of such notice, the Paying Agent shall calculate the Special Mandatory Redemption Price and shall notify the Escrow Agent, the Trustee, Spinco and Frontier if the amount of the Escrowed Funds is less than the Special Mandatory Redemption Price and the amount of such shortfall. At or prior to 2:00 p.m. (New York City time) on the Special Redemption Date, the Escrow Agent shall as promptly as practicable release from the escrow account to the Paying Agent as per the written instructions of the Trustee (which shall specify the Special Mandatory Redemption Price and the wire payment instructions), an amount equal to the lesser of (A) the amount of funds in the escrow account and (B) the aggregate amount of the Special Mandatory Redemption Price.

Any notice which is mailed in the manner herein provided shall be conclusively presumed to have been duly given, whether or not the Holder receives the notice. Failure to give notice by mail, or any defect in the notice to the Holder of any Notes of such

41

series designated for redemption as a whole or in part shall not affect the validity of the proceedings for the redemption of any other Note. The notice of redemption to each such Holder shall specify (i) the principal amount of each Note held by such Holder to be redeemed, (ii) the date fixed for redemption, (iii) the redemption price, (iv) the place or places of payment, (v) the CUSIP number relating to the Notes, (vi) that payment will be made upon presentation and surrender of the Notes, (vii) whether interest, if any, accrued to the date fixed for redemption will be paid as specified in such notice and (viii) whether on and after said date interest, if any, thereon or on the portions thereof to be redeemed will cease to accrue.

The notice of redemption of Notes to be redeemed at the option of the Issuer shall be given by the Issuer or, at the Issuer’s request, by the Trustee in the name and at the expense of the Issuer.

On or before the redemption date specified in the notice of redemption given as provided in this Section 3.04, the Issuer shall deposit with the Trustee or with one or more Paying Agents (or, if the Issuer is acting as its own Paying Agent, set aside, segregate and hold in trust as provided in Section 4.04(b)) an amount of money sufficient to redeem on the redemption date all the Notes of such series so called for redemption at the appropriate redemption price, together with accrued interest, if any, to the date fixed for redemption. The Issuer shall deliver to the Trustee at least 45 days prior to the date fixed for redemption (but no later than the receipt by the Holders of the notice of redemption) (unless a shorter notice period shall be satisfactory to the Trustee) an Officers’ Certificate stating the aggregate principal amount of Notes of such series to be redeemed. In case of a redemption at the election of the Issuer prior to the expiration of any restriction on such redemption, the Issuer shall deliver to the Trustee, prior to the giving of any notice of redemption to Holders pursuant to this Section, an Officers’ Certificate stating that such restriction has been complied with.

Section 3.05. Payment of Notes Called for Redemption .

If notice of redemption has been given as provided by this Article 3, the Notes or portions of Notes specified in such notice shall become due and payable on the date and at the place or places stated in such notice at the applicable redemption price, together with interest, if any, accrued to the date fixed for redemption, and on and after said date (unless the Issuer shall default in the payment of such Notes at the redemption price, together with unpaid interest, if any, accrued to said date) interest, if any, on the Notes or portions of Notes so called for redemption shall cease to accrue, and such Notes shall cease from and after the date fixed for redemption, except as provided herein, to be entitled to any benefit or security under this Indenture, and the Holders thereof shall have no right in respect of such Notes except the right to receive the redemption price thereof and accrued and unpaid interest thereon, if any, to the date fixed for redemption. On presentation and surrender of such Notes at a place of payment specified in said notice, said Notes or the specified portions thereof shall be paid and redeemed by the Issuer at the applicable redemption price, together with interest, if any, accrued thereon to the date fixed for redemption; provided that payment of interest, if any, becoming due on or prior

42

to the date fixed for redemption shall be payable to the Person in whose name the Note is registered at the close of business on the related interest record date subject to the terms and provisions of this Section 3.05.

If any Note called for redemption shall not be so paid upon surrender thereof for redemption, the redemption price shall, until paid or duly provided for, bear interest from the date fixed for redemption at the rate of interest borne by such Note.

Upon presentation of any Note redeemed in part only, the Issuer shall execute and the Trustee shall authenticate and deliver to or on the order of the Holder thereof, at the expense of the Issuer, a new Note or Notes, and of like series and tenor, of authorized denominations, in principal amount equal to the unredeemed portion of the Note so presented.

Section 3.06. Exclusion of Certain Securities from Eligibility for Selection for Redemption .

Notes shall be excluded from eligibility for selection for redemption pursuant to Section 3.02 hereof if they are identified by registration and certificate number in an Officers’ Certificate delivered to the Trustee at least 45 days prior to the last date on which notice of redemption may be given as being owned of record and beneficially by, and not pledged or hypothecated by either (a) the Issuer, or (b) a Person specifically identified in such written statement as an Affiliate of the Issuer.

Section 3.07. Partial Redemption .

If less than all of the Notes of a series are to be redeemed pursuant to Section 3.02 hereof, selection of the Notes for redemption shall be made by the Trustee as follows:

(a) if the Notes of such series are listed on any national securities exchange, in compliance with the requirements of such national securities exchange; or

(b) if the Notes of such series are not so listed, on a pro rata basis (subject to the procedures of the Depositary) or, to the extent a pro rata basis is not permitted, in such manner as the Trustee shall deem to be fair and appropriate.

No Note of $2,000 in principal amount or less shall be redeemed in part. If any Note is to be redeemed in part only, the notice of redemption mailed pursuant to Section 3.04 relating to such Note will state the portion of the principal amount to be redeemed. A new Note of the same series in principal amount equal to the unredeemed portion shall be issued upon cancellation of the original Note.

Notice of the redemption shall be given only after such selection has been made. Notes may be redeemed in part in multiples equal to the minimum authorized denomination for Notes or any multiple thereof. The Trustee shall promptly notify the Issuer in writing of the Notes selected for redemption and, in the case of any Notes selected for partial redemption, the principal amount thereof to be redeemed. For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Notes shall relate, in the case of any Note redeemed or to be redeemed only in part, to the portion of the principal amount of such Note which has been or is to be redeemed.

Any Note so accepted for payment will cease to accrue interest on and after the Change of Control Payment Date.

Notwithstanding the foregoing, the Issuer shall not be required to make a Change of Control Offer upon a Change of Control Triggering 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 4.09 applicable to a Change of Control Offer made by the Issuer and purchases all Notes properly tendered and not withdrawn under the Change of Control Offer.

The Issuer may make a Change of Control Offer in advance of a Change of Control Triggering Event, and conditional upon the occurrence of such Change of Control Triggering Event, if a definitive agreement is in place for the Change of Control Triggering Event at the time of making the Change of Control Offer.

The Trustee shall be entitled to receive, and may conclusively rely upon, an Officers’ Certificate specifying that an Investment Grade Rating has occurred and stating that, pursuant to this Section 4.10, the Issuer has been released from its obligations to comply with Section 4.07.

(a) to file and prove a claim or claims for the whole amount of principal and interest, if any, owing and unpaid in respect of such Notes, and, in the case of any judicial proceedings, to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for amounts payable to the Trustee under Section 7.07) and of the Holders of such Notes allowed in any judicial proceedings relative to the Issuer upon such Notes, or to the creditors or property of the Issuer; and

Section 6.06. Limitation on Suits by Noteholders .

No delay or omission of the Trustee or of any Holder of such Notes to exercise any right or remedy accruing upon any Event of Default with respect to any such series of Notes occurring and continuing as aforesaid shall impair any such right or remedy or shall be construed to be a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Indenture, any Note or law to the Trustee or to the Holders of such Notes may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or, subject to Section 6.06, by the Holders of such Notes.

Section 6.09. Control by Holders of Notes .

The Holders of a majority in aggregate principal amount of the Notes of each affected series at the time Outstanding shall have the right to 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 such series of Notes by this Indenture; provided that such direction shall not be otherwise than in accordance with law and the provisions of this Indenture and shall not expose the Trustee to personal liability; and provided further , that (subject to the provisions of Section 7.01) the Trustee shall have the right to decline to follow any such direction (a) if the Trustee, being advised by counsel, shall determine that the action or proceeding so directed may not lawfully be taken; or (b) if the Trustee by its board of directors, the executive committee or a trust committee of directors or Responsible Officers of the Trustee shall determine in good faith that the action or proceedings so directed would involve the Trustee in personal liability; or (c) if the Trustee in good faith shall so determine that the actions or forbearances specified in or pursuant to such direction would be unduly prejudicial to the interests of the Holders of the Notes of such series not joining in the giving of said direction.

59

In the case of any such waiver, the Issuer, the Trustee and the Holders of all of the Notes of such series shall be restored to their former positions and rights hereunder, respectively, and such default shall cease to exist and be deemed to have been cured and not to have occurred for purposes of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon.

Section 7.03. Individual Rights of Trustee .

Section 7.05. Notice of Defaults .

If a Default or Event of Default with respect to any series of Notes occurs and is continuing and if it is known to the Trustee, the Trustee shall mail to Holders of such Notes, as their names and addresses appear in the Security Register, a notice of the Default or Event of Default within 90 days after it occurs, unless such default shall have been cured or waived. Except in the case of a Default or Event of Default in payment of principal of, premium, if any, or interest on any such Note, the Trustee may withhold and shall be protected in withholding the notice if and so long as its Responsible Officers in good faith determine that withholding the notice is in the interests of the Holders of such Notes. In the case of any Default of the character specified in Section 6.01(c) no such notice to Holders shall be given until at least 90 days after the occurrence thereof.

Section 7.06. Reports by Trustee to Holders .

Within 60 days after each May 15 beginning with the May 15 following the date of this Indenture, and for so long as Notes of any series remain Outstanding, the Trustee shall mail to the Holders of such Notes, as their names and addresses appear in the Security Register, a report dated as of such reporting date, in accordance with, and to the extent required under, TIA § 313(a), and the Trustee shall otherwise comply with TIA § 313.

A copy of each report at the time of its mailing to the Holders shall be mailed to the Issuer and filed with the Commission and each stock exchange on which Notes of a series are listed in accordance with TIA § 313(d). The Issuer shall promptly notify the Trustee when the Notes of any series are listed on any stock exchange and any delisting thereof.

Section 7.07. Compensation and Indemnity .

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

64

The Issuer, or such other Person acceptable to the Trustee, shall indemnify the Trustee or any predecessor Trustee against and hold each harmless against any and all losses, claims, damages, penalties, fines, liabilities or expenses, including incidental and out-of-pocket expenses and reasonable attorneys’ fees (for purposes of this Article, “losses”) incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture, including the costs and expenses of enforcing this Indenture against the Issuer (including this Section 7.07) and defending itself against any claim (whether asserted by the Issuer or any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, except to the extent such losses may be attributable to its gross negligence, willful misconduct or bad faith. The Trustee shall notify the Issuer promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Issuer shall not relieve the Issuer of its obligations under this Section 7.07. The Issuer, or such other Person acceptable to the Trustee, shall defend the claim, and the Trustee shall cooperate in the defense. The Trustee may have separate counsel if the Trustee has been reasonably advised by counsel that there may be one or more legal defenses available to it that are different from or additional to those available to the Issuer or in the reasonable judgment of such counsel it is advisable for the Trustee to engage separate counsel, and the Issuer shall pay the reasonable fees and expenses of such counsel. The Issuer need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld. The Issuer need not reimburse any expense or indemnify against any loss incurred by the Trustee through the Trustee’s own gross negligence, willful misconduct or bad faith.

The obligations of the Issuer under this Section 7.07 shall survive the satisfaction and discharge of this Indenture, the resignation or removal of the Trustee and payment in full of the Notes of all series issued pursuant to this Indenture through the expiration of the applicable statute of limitations.

To secure the Issuer’s payment obligations in this Section, the Trustee shall have a Lien prior to the Notes of each series on all money or property held or collected by the Trustee, except that held in trust to pay principal of, premium, if any, and interest on particular Notes of such series. Such Lien shall survive the satisfaction and discharge of this Indenture. For the avoidance of doubt, this provision shall not (i) serve to create a Lien on the Escrowed Funds, as defined in the Escrow Agreement, or any property of Spinco or Frontier, or (ii) serve to create a Lien prior to the Merger.

In addition to and without prejudice to its other rights hereunder, when the Trustee incurs expenses or renders services after an Event of Default specified in Sections 6.01(d) or 6.01(e) with respect to any series of Notes, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law.

“Trustee” for purposes of this Section shall include any predecessor Trustee; provided, however , that the gross negligence, willful misconduct or bad faith of any Trustee hereunder shall not affect the rights of any other Trustee hereunder.

65

Section 7.08. Replacement of Trustee .

A resignation or removal of the Trustee and appointment of a successor Trustee with respect to any or all series of Notes shall become effective only upon the successor Trustee’s acceptance of appointment as provided in this Section 7.08.

The Trustee with respect to any or all series of Notes may resign in writing at any time upon 30 days’ prior written notice to the Issuer and be discharged from the trust hereby created by so notifying the Issuer. If an instrument of acceptance by a successor Trustee shall not have been delivered to the Trustee within 30 days after giving such notice of resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor Trustee. The Holders of a majority in aggregate principal amount of the then Outstanding Notes of any series of Notes may remove the Trustee by so notifying the Trustee and the Issuer in writing.

If, with respect to the applicable series of Notes:

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

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

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

(d) the Trustee becomes incapable of acting,

then (i) the Issuer may remove the Trustee or (ii) subject to Section 6.11, any Holder who has been a bona fide Holder of a Note for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason with respect to any series of Notes (the Trustee in such event being referred to herein as the retiring Trustee), the Issuer shall promptly appoint a successor Trustee for each such affected series of Notes (it being understood that any such successor Trustee may be appointed with respect to the Notes of one or more or all of such series and that at any time there shall be only one Trustee with respect to the Notes of any particular series).
