(c)                                  Liens by a Subsidiary as security for indebtedness owed to the Company or any Subsidiary;

(e)                                  any extension, renewal or replacement (or successive extensions, renewals or replacements), in whole or in part, of any Lien existing on the Issue Date or referred to in the foregoing clauses including in connection with the refinancing of indebtedness of the Company and its Subsidiaries secured by such Lien; and

(f)                                   other Liens not permitted by any of the foregoing clauses (a) through (e) on any property, now owned or hereafter acquired; provided, that, no such Liens shall be incurred pursuant to this subsection (f) if the aggregate principal amount of outstanding indebtedness (without duplication for any guarantee of such indebtedness) and Capital Leases secured by Liens incurred pursuant to this subsection (f) subsequent to the Issue Date, including the Lien proposed to be incurred, shall exceed 20% of Consolidated Tangible Assets after giving effect to such incurrence and the use of proceeds of such indebtedness or Capital Leases.

Section 6.2                 Release of Liens.  Any Lien that is granted to secure the Notes pursuant to Section 6.1 shall be automatically released and discharged at the same time as the release (other than through the exercise of remedies with respect thereto) of each Lien that gave rise to such obligation to secure the Notes under Section 6.1.

Section 6.3                 Merger, Consolidation or Sale of All or Substantially All Assets.  Except as may be provided in a Future Supplemental Indenture, for the benefit of the Holders of the Notes but no other series of Securities under the Indenture, whether now or hereafter issued and Outstanding, Section 8.01 of the Base Indenture is hereby amended and restated in its entirety as follows with respect to the Notes by this Section 6.3:

(ii)                                  the Successor Company (if other than the Company) expressly assumes all of the obligations of the Company under the Notes and the Indenture pursuant to a supplemental indenture;

10

(iii)                               immediately after giving effect to such transaction, no Default or Event of Default shall have occurred and be continuing; and

(iv)                              the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that such consolidation, merger, winding up or disposition, and such supplemental indenture, if any, comply with the Indenture.

(b)                                 The Company will be released from its obligations under the Indenture and the Successor Company will succeed to, and be substituted for, and may exercise every right and power of, the Company under the Indenture and the Notes; provided, that in the case of a lease of all or substantially all its assets, the Company will not be released from the obligation to pay the principal of and interest on the Notes.

(c)                                  For purposes of this Section 6.2, Aircraft Asset leasing in the ordinary course of business of the Company or any of its Subsidiaries shall not be considered the leasing of “all or substantially all” of the Company’s consolidated assets.

ARTICLE VII.
DEFAULTS AND REMEDIES

Section 7.1                 Events of Default.  Except as may be provided in a Future Supplemental Indenture, for the benefit of the Holders of the Notes but no other series of Securities under the Indenture, whether now or hereafter issued and Outstanding, Section 5.01 of the Base Indenture is hereby amended and restated in its entirety as follows with respect to the Notes by this Section 7.1:

Each of the following is an “Event of Default” with respect to any tranche of Notes:

(c)                                  default in the performance, or breach, of any covenant or warranty of the Company in the Indenture with respect to the Notes (other than a covenant or warranty with respect to which a default in performance or breach is elsewhere in this Section 7.1 specifically addressed or which covenant or warranty has been included in the Indenture solely for the benefit of one or more series or tranches notes other than the Notes), and continuance of such default or breach for a period of 90 consecutive days after there has been given, by registered or certified mail, to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in aggregate principal amount of all Outstanding Notes affected thereby, a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a “Notice of Default” under the Indenture;

(d)                                 default under any mortgage, indenture (including the Indenture) or instrument under which there is issued, or which secures or evidences, any indebtedness for borrowed money of the Company (or the payment of which is guaranteed by the Company) (other than indebtedness owed to any Subsidiary or Non-Recourse Indebtedness of the Company) now existing or hereinafter created, which default shall constitute a failure by the Company to pay principal in an amount exceeding $100.0 million (the “Threshold Amount”) when due and payable by the Company at final stated maturity, after expiration of any applicable grace period with respect thereto (such default, a “payment default”), or shall have resulted in an aggregate principal amount of such indebtedness exceeding the Threshold Amount becoming due and payable by the Company prior to the date on which it would otherwise have become due and payable (such default, an “acceleration default”); provided, however, that in connection with any series of the Convertible Notes, (i) any conversion of such indebtedness by a holder thereof into shares of common stock, cash or a combination of cash and shares of common stock, (ii) the rights of holders of such indebtedness to convert into shares of common stock, cash or a combination of cash and shares of common stock and (iii) the rights of holders of such indebtedness to require any repurchase by the Company of such indebtedness in cash upon a fundamental change shall not, in itself, constitute an Event of Default hereunder; or

11

(e)                      (i)                                              the Company, pursuant to or within the meaning of any Bankruptcy Law: (A) commences proceedings to be adjudicated bankrupt or insolvent; (B) consents to the institution of bankruptcy or insolvency proceedings against it, or the filing by it of a petition or answer or consent seeking an arrangement of debt, reorganization, dissolution, winding up or relief under applicable Bankruptcy Law; (C) consents to the appointment of a receiver, interim receiver, receiver and manager, liquidator, assignee, trustee, sequestrator or other similar official of it or for all or substantially all of its property; (D) makes a general assignment for the benefit of its creditors; or (E) makes an admission in writing of its inability to pay its debts generally as they become due; or

(ii)                                  a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: (A) is for relief against the Company in a proceeding in which the Company is to be adjudicated bankrupt or insolvent; (B) appoints a receiver, interim receiver, receiver and manager, liquidator, assignee, trustee, sequestrator or other similar official of the Company; or (C) orders the liquidation, dissolution or winding up of the Company; and the order or decree remains unstayed and in effect for 90 consecutive days (any such Event of Default specified in this clause (e), for purposes of the Notes, shall constitute a “Bankruptcy Default”).

Within 60 days following the date on which the Company becomes aware of a Default or receives notice of such Default, as applicable, if such Default is continuing, the Company shall deliver a certificate to the Trustee specifying any events which would constitute a Default, their status and what action the Company is taking or proposing to take in respect thereof.

In the event of a declaration of acceleration of any tranche of Notes solely because an Event of Default described in Section 7.1(d) above has occurred and is continuing, the declaration of acceleration of such Notes shall be automatically rescinded and annulled if (i) the default or defaults triggering such Event of Default pursuant to Section 7.1(d) shall be remedied or cured by the Company or waived by the holders of the relevant indebtedness within 30 days after the declaration of acceleration with respect thereto; (ii) the rescission and annulment of the acceleration of such Notes would not conflict with any judgment or decree of a court of competent jurisdiction; and (iii) all Events of Default with respect to such Notes, except non-payment of principal of, or premium, if any, or interest on, the Notes that have become due solely by such declaration of acceleration of the Notes of such tranche, as the case may be, have been cured or waived as provided in the Indenture.

Section 7.2                 Acceleration.

(a)                                 Except as may be provided in a Future Supplemental Indenture, for the benefit of the Holders but no other series of Securities under the Indenture, whether now or hereafter issued and Outstanding, the first three paragraphs of Section 5.02 of the Base Indenture are hereby replaced with the following with respect to the Notes:

“If an Event of Default (other than an Event of Default described in Section 7.1(e) of the Supplemental Indenture) occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the Outstanding Notes affected thereby may declare the principal of, premium, if any, and accrued and unpaid interest, if any, on all the Notes affected thereby to be due and payable by notice in writing to the Company (and to the Trustee if given by Holders). Upon such a declaration, such principal, premium, if any, and accrued and unpaid interest, if any, will be due and payable immediately.

If an Event of Default described in Section 7.1(e) occurs and is continuing, the principal of, premium, if any, and accrued and unpaid interest, if any, on all the Notes will become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holders.”

(b)                                 Except as may be provided in a Future Supplemental Indenture, for the benefit of the Holders but no other series of Securities under the Indenture, whether now or hereafter issued and Outstanding, the fourth paragraph of Section 5.02 of the Base Indenture is hereby amended by replacing the period at the end of clause (b) thereof with “; and” and adding the following clause (c) thereafter: “(c) such rescission would not conflict with any judgment or decree of a court of competent jurisdiction.”

12

Section 7.3                 Control by Holders.  Notwithstanding Section 5.12 of the Base Indenture, the Trustee may refuse to follow any direction that conflicts with any law, rule, regulation or court order or the Indenture or the Notes, or that the Trustee determines in good faith is unduly prejudicial to the rights of any Holder or that would involve the Trustee in personal liability. Any application by the Trustee for written instructions from the requisite amount of Holders may, at the option of the Trustee, set forth in writing any action proposed to be taken or omitted by the Trustee under the Indenture and the date on and/or after which such action shall be taken or such omission shall be effective. The Trustee shall not be liable for any action taken by, or omission of, the Trustee in accordance with a proposal included in such application on or after the date specified in such application unless prior to taking any such action (or the effective date in the case of an omission), the Trustee shall have received written instructions from the requisite amount of Holders in response to such application specifying the action to be taken or omitted.

Section 7.4                 Waivers.  It shall not be necessary for any Act of Holders to approve the particular form of any waiver, but it shall be sufficient if such Act shall approve the substance thereof.  A consent to any waiver by any Holder given in connection with a sale, tender or exchange of such Holder’s Notes will not be rendered invalid by such sale, tender or exchange.

ARTICLE VIII.
DEFEASANCE

Section 8.1                 Covenant Defeasance.  The covenants provided pursuant to Section 3.01(r), 9.01(b) or 9.01(g) of the Base Indenture for purposes of Section 13.03 of the Base Indenture are the covenants in Article VI and Article X of this Supplemental Indenture and Section 5.15 of the Base Indenture.

Section 10.1          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, if any, to redeem all of the Notes, as may be set forth in an Officers’ Certificate to this Supplemental Indenture, the Company will make an offer to purchase all of the Notes (the “Change of Control Offer”) at a purchase price in cash equal to 101% of the principal amount of the Notes plus accrued and unpaid interest, if any, to the date of purchase (the “Change of Control Payment”), subject to the right of Holders of record on the applicable Regular Record Date to

13

receive interest due on an Interest Payment Date falling on or prior to such payment date. Within 30 days following the date upon which a Change of Control Repurchase Event occurred, or at the Company’s option, prior to any Change of Control but after the public announcement of the pending Change of Control, unless the Company has exercised its right, if any, to redeem all of the Notes as may be set forth in an Officers’ Certificate to this Supplemental Indenture, the Company will mail a notice of such Change of Control Offer to each Holder or otherwise give notice, which will govern the terms of the Change of Control Offer, in accordance with the applicable procedures of DTC, with a copy to the Trustee, stating:

(i)                                     that a Change of Control Offer is being made pursuant to this Section 10.1 and that all Notes validly tendered pursuant to such Change of Control Offer will be accepted for purchase by the Company at a purchase price in cash equal to 101% of the principal amount of such Notes plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of Holders of record on the applicable Regular Record Date to receive interest due on an Interest Payment Date falling on or prior to such payment date);

(ii)                                  the purchase date (which shall be no earlier than 30 days nor later than 60 days from the date such notice is mailed or given, other than as may be required by law) (the “Change of Control Payment Date”);

(iii)                               if sent prior to the date of consummation of the Change of Control, that the Change of Control Offer is conditioned on the Change of Control being consummated on or prior to the Change of Control Payment Date; provided, that if a Change of Control is consummated after a proposed Change of Control Payment Date and such Change of Control Offer is therefore not consummated, the Company shall make a Change of Control Offer in accordance with this Section 10.1 within 30 days following the later of the consummation of such Change of Control or a Below Investment Grade Rating Event;

(iv)                              that Notes must be tendered in multiples of $1,000, and any Note not validly tendered will remain outstanding and continue to accrue interest;

(v)                                 that, unless the Company defaults in the payment of the Change of Control Payment, any Note accepted for payment pursuant to the Change of Control Offer will cease to accrue interest on and after the Change of Control Payment Date;

(vi)                              that Holders electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender such Notes, with the form entitled “Option of Holder to Elect Purchase” on the reverse of such Notes completed, to the Paying Agent specified in the notice at the address specified in the notice, or transfer their Notes to the Paying Agent by book-entry transfer pursuant to the applicable procedures of the Paying Agent, prior to the close of business on the third Business Day preceding the Change of Control Payment Date;

(vii)                           that Holders shall be entitled to withdraw their tendered Notes and their election to require the Company to purchase such Notes; provided, that the Paying Agent receives at the address specified in the notice, not later than the close of business on the 30th day following the date of the Change of Control notice, a telegram, facsimile transmission or letter setting forth the name of the Holder of the Notes, the principal amount of Notes tendered for purchase, and a statement that such Holder is withdrawing its tendered Notes and its election to have such Notes purchased;

(viii)                        that if a Holder is tendering less than all of its Notes, such Holder will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered (the unpurchased portion of the Notes must be equal to $1,000 or an integral multiple of $1,000 in excess thereof); and

(ix)                              the other instructions, as determined by the Company, consistent with this Section 10.1 that a Holder must follow.

14

The notice, if mailed or given in a manner herein provided, shall be conclusively presumed to have been given, whether or not the Holder receives such notice. If (A) the notice is mailed or given in a manner herein provided and (B) any Holder fails to receive such notice or a Holder receives such notice but it is defective, such Holder’s failure to receive such notice or such defect shall not affect the validity of the proceedings for the purchase of the Notes as to all other Holders that properly received such notice without defect.

(b)                                 On the Change of Control Payment Date, the Company will, to the extent lawful:

(i)                                     accept for payment all Notes or portions of Notes (of integral multiples of $1,000) validly tendered pursuant to the Change of Control Offer;

(ii)                                  deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes so tendered;

(iii)                               deliver or cause to be delivered to the Trustee for cancellation the Notes so accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Company in accordance with this Section 10.1; and

(iv)                              deliver to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for in the Indenture relating to the making of such Change of Control Payment have been complied with.

(c)                                  The Paying Agent will promptly pay to each Holder of Notes so tendered the Change of Control Payment for such Notes, and the Trustee or the Authenticating Agent, as applicable, will promptly authenticate, upon receipt of an authentication order, and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided, that each such new Note will be in a principal amount of $1,000 or integral multiples of $1,000 in excess thereof.

(d)                                 If the Change of Control Payment Date is on or after a Regular Record Date and on or before the related Interest Payment Date, any accrued and unpaid interest to the Change of Control Payment Date will be paid on the relevant Interest Payment Date to the Person in whose name a Note is registered at the close of business on such Regular Record Date.

(e)                                  Prior to making a Change of Control Payment, and as a condition to such payment (i) the requisite holders of each issue of indebtedness issued under an indenture or other agreement that would be violated by the making of such payment shall have consented to such Change of Control Payment being made and waived the event of default, if any, caused by the Change of Control or (ii) the Company will repay all outstanding indebtedness issued under an indenture or other agreement that would be violated by the making of a Change of Control Payment or the Company will offer to repay all such indebtedness, make payment to the holders of such indebtedness that accept such offer and obtain waivers from the requisite remaining holders of such indebtedness of any event of default arising under the relevant indenture or other agreement as a result of the Change of Control. The Company covenants to effect such repayment or obtain such consent prior to making a Change of Control Payment, it being a default of this Section 10.1 if the Company fails to comply with such covenant.

(f)                                   The Company will not be required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 10.1 applicable to a Change of Control Offer made by the Company and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer.

(g)                                  The Company will comply, to the extent applicable, with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws or regulations in connection with the repurchase of Notes pursuant to a Change of Control Offer. To the extent that the provisions of any securities laws or regulations conflict with provisions of the Indenture, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Indenture by virtue of the conflict.

15

(h)                                 Other than as specifically provided in this Section 10.1, any purchase pursuant to this Section 10.1 shall be made pursuant to the provisions of Sections 11.03, 11.05 and 11.07 of the Base Indenture.

(i)                                     Notwithstanding anything to the contrary in the foregoing clauses (a) though (h), the Company’s obligation to make a Change of Control Offer may be waived or modified with the written consent of the Holders of a majority in principal amount of the Notes.

The Company may at any time issue Additional Notes under the Indenture in unlimited amounts having the same terms as the Notes, except as otherwise permitted by the Indenture. Any such Notes, together with this Note, will constitute a single series of Securities under the Indenture.  The Notes will initially be issued in the form of one or more Global Securities.  Except as provided in the Indenture, a Global Security shall not be exchangeable for one or more definitive securities.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Notes to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Notes at the time Outstanding. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Notes at the time Outstanding, on behalf of the Holders of all Notes affected thereby, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note.

As provided in and subject to the provisions of the Indenture, the Holder of this Note shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Notes, the Holders of at least 25% in principal amount of the Notes affected thereby at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee indemnity or security reasonably satisfactory to it, and the Trustee shall not have received from the Holders of a majority in principal amount of Notes affected thereby at the time Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Note for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein.

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any interest on this Note at the times, place and rate, and in the coin or currency, herein prescribed.
