The weekly average yields of U.S. Treasury Notes will be determined by referring to the most recent statistical release published by the Federal Reserve Bank of New York and designated “H.15(519) Selected Interest Rates” or any successor release (the “H.15 Statistical Release”). If the H.15 Statistical Release contains a weekly average yield for U.S. Treasury Notes having a constant maturity that is the same as the Remaining Term, then the Treasury Yield will be equal to that weekly average yield. In all other cases, the Treasury Yield will be calculated by interpolation, on a straight-line basis, between the weekly average yields on the U.S. Treasury Notes that have a constant maturity closest to and greater than the Remaining Term and the U.S. Treasury Notes that have a constant maturity closest to and less than the Remaining Term (in each case as set forth in the H.15 Statistical Release). Any weekly average yields as calculated by interpolation will be rounded to the nearest 1/100th of 1% with any figure of 1/200% or above being rounded upward. If weekly average yields for U.S. Treasury Notes are not available in the H.15 Statistical Release or otherwise, then the Treasury Yield will be calculated by interpolation of comparable rates selected by the Independent Investment Banker.

“Voting Stock” of any specified Person as of any date means the Capital Stock of such Person that is at the time entitled to vote in the election of the board of directors (or similar governing body) of such Person.

“Withholding Tax” has the meaning set forth in Section 312 of the Indenture (as added by Section 2.2 of this Second Supplemental Indenture).

2.2 Amendments to Article Three of the Original Indenture (Tax Additional Amounts).

Article Three of the Original Indenture is hereby amended in respect of, and applicable to, the Notes and only in respect of, and applicable to, the Notes by adding the following section as Section 312:

SECTION 312. Tax Additional Amounts.

The Company shall pay any amounts due with respect to the payments on the Notes without deduction or withholding for any and all present and future withholding taxes, levies, imposts and charges (each, a “Withholding Tax”) imposed by or for the account of the Cayman Islands or any other jurisdiction in which the Company is resident for tax purposes or any political subdivision or taxing authority of such jurisdiction (the “Taxing Jurisdiction”), unless such withholding or deduction is required by law. If such deduction or withholding is at any time required, the Company will (subject to compliance by such Holder with any relevant administrative requirements) pay each Holder additional amounts (“Tax Additional Amounts”) as will result in such Holder’s receipt of such amounts as it would have received had no such withholding or deduction been required.

If the Taxing Jurisdiction requires the Company to deduct or withhold any Withholding Tax, the Company will (subject to compliance by a Holder with any relevant administrative requirements) pay such Tax Additional Amounts in respect of principal amount, Redemption Price and interest (if any) in accordance with the terms of the Notes and the Indenture; provided, however, that the foregoing shall not apply to:

(a) any Withholding Tax that would not be payable or due but for the fact that (1) the Holder of a Note (or a fiduciary, settlor, beneficiary of, member or shareholder of, such Holder, if such Holder is an estate, trust, partnership or corporation) is a domiciliary, national or resident of, or engaging in business or maintaining a permanent establishment or fixed base or being physically present in, the Taxing Jurisdiction or otherwise having some present or former connection with the Taxing Jurisdiction other than the holding or ownership of the Note or the collection of principal amount, Redemption Price and interest (if any), in accordance with the terms of the Note and the Indenture or the enforcement of the Note or (2) where presentation is required, the Note was presented more than 30 days after the date such payment became due or was provided for, whichever is later;

(b) any Withholding Tax attributable to any estate, inheritance, gift, sales, transfer, excise, personal property or similar tax, levy, impost or charge;

(c) any Withholding Tax attributable to any tax, levy, impost or charge that is payable otherwise than by withholding from payment of principal amount, Redemption Price and interest (if any);

(d) any Withholding Tax that would not have been imposed but for the failure to comply with certification, identification, information, documentation or other reporting requirements concerning the nationality, residence, identity or connections with the relevant tax authority of the Holder or beneficial owner of a Note, if (1) this compliance is required by statute or by regulation as a precondition to relief or exemption from such Withholding Tax and (2) at least 30 days prior to the first scheduled payment date for which compliance will be required, the Guarantor has notified Holders or beneficial owners of Notes that they must comply with such certification, identification, information, documentation or other reporting requirements;

(e) any Withholding Tax to the extent a Holder of a Note is entitled to a refund or credit in the Taxing Jurisdiction of amounts required to be withheld by such Taxing Jurisdiction; or

(f) any combination of the instances described in (a) through (e).

With respect to clause (e), above, in the absence of evidence satisfactory to the Company, the Company may conclusively presume that a Holder of the Note is entitled to a refund or credit of all amounts required to be withheld. The Company shall not be required to pay any Tax Additional Amounts to any Holder of a Note who is a fiduciary or partnership or other than the sole beneficial owner of the Note to the extent that a beneficiary or settlor with respect to such fiduciary, or a member of such partnership or a beneficial owner thereof, would not have been entitled to the payment of such Tax Additional Amounts had such beneficiary, settlor, member or beneficial owner been the Holder of the Note.

The Guarantor shall, with respect to its Guarantee of the Notes, pay Tax Additional Amounts, subject to the above requirements and limitations, with respect to any Withholding Tax imposed by or for the account of any Taxing Jurisdiction with respect to any payments made under the Guarantee.

The Guarantor shall furnish to the Trustee documentation reasonably satisfactory to the Trustee evidencing the payment of any Withholding Taxes with respect to payments on the Notes. Copies of such receipts will be made available to the Holders of the Notes or beneficial owners of the Notes upon written request.

Tax Additional Amounts shall be treated as Additional Amounts for purposes of the Indenture. All references in the Indenture or the Notes to “interest” shall include (without duplication) any Tax Additional Amounts due with respect thereto.

2.3 Amendments to Article Four of the Original Indenture (Discharge of Liability on Securities of Any Series).

Article Four of the Original Indenture is hereby amended in respect of, and applicable to, the Notes and only in respect of, and applicable to, the Notes by

(a) amending and restating in its entirety Section 403(1) as follows:

(1)

the Company has complied with the provisions of Section 401 of this Indenture (other than any additional conditions specified pursuant to Sections 301 and 401(3) and except that the Company shall have received from, or there has been published by, the United States Internal Revenue Service a ruling to the effect that the Holders of Securities of such series will not recognize income, gain or loss for United States federal income tax purposes as a result of such deposit, satisfaction and discharge and will be subject to United States federal income tax on the same amount and in the same manner and at the same time as would have been the case if such deposit, satisfaction and discharge had not occurred) with respect to all Outstanding Securities of such series,

and

(b) adding thereto the following new Section 405, which shall constitute additional means of satisfaction and discharge and other conditions with respect to the Notes as contemplated by clause (C) of Section 401(1) and Section 401(3), respectively:

(1) the Company has complied with the provisions of Section 401 of this Indenture (other than any additional conditions specified pursuant to Sections 301 and 401(3) and except that the Opinion of Counsel referred to in Section 401(5) shall state to the effect that the Holders of Notes will not recognize income, gain or loss for United States federal income tax purposes as a result of such deposit and defeasance and will be subject to United States federal income tax on the same amount and in the same manner and at the same time as would have been the case if such deposit and defeasance had not occurred) with respect to all Outstanding Notes;

(2) the Company has delivered to the Trustee a Company Request requesting such defeasance;

Notwithstanding the prior sentence, any obligation of the Company to file reports with the Trustee pursuant to the prior sentence shall be deemed to be satisfied for so long as the Guarantor (or any other person that is a successor to the Guarantor’s reporting obligations to the Commission) shall file with the Trustee within the time period provided in the prior sentence copies of the annual reports and of the information, documents and other reports (or copies of such portions of any of the foregoing as the Commission may from time to time by rules and regulations prescribe) that the Guarantor (or any other person that is a successor to the Guarantor’s reporting obligations to the Commission) may be required to file with the Commission pursuant to Section 12 or Section 15(d) of the Exchange Act, and such annual reports, information, documents and other reports contain such information relating to the Company as is required by the rules and regulations of the Commission. Delivery of such reports, information, documents and other reports to the Trustee is for informational purposes only and the Trustee’s receipt of such reports, information, documents and other reports shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company’s or the Guarantor’s compliance with any of their covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates).

2.5 Amendments to Article Eight of the Original Indenture (Consolidation, Amalgamation, Conveyance, Transfer or Lease).

Article Eight of the Original Indenture is hereby amended in respect of, and applicable to, the Notes and only in respect of, and applicable to, the Notes by adding thereto the following new Sections 803 and 804:

SECTION 803. Guarantor May Consolidate, Etc., Only on Certain Terms.

The Guarantor shall not consolidate or amalgamate with or merge into any Person, or sell, lease, convey, transfer or otherwise dispose of all or substantially all of its properties and assets to any Person, other than a direct or indirect Wholly Owned Subsidiary of the Guarantor, unless:

(1)

either (a) the Guarantor shall be the continuing Person or (b) the Person formed by such consolidation or amalgamation or into which the Guarantor is merged, or the Person that acquires, by sale, lease, conveyance, transfer or other disposition, all or substantially all of the properties and assets of the Guarantor, shall expressly assume, by a supplemental indenture, the Guarantee, and the performance of the Guarantor’s covenants and obligations under this Indenture and the Guarantee;

(2)

immediately after giving effect to such transaction or series of transactions, no Default or Event of Default shall have occurred and be continuing or would result therefrom; and

(3)

the Guarantor has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that such consolidation, amalgamation, merger, sale, lease, conveyance, transfer or other disposition and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture complies with Sections 803 and 804 and that all conditions precedent herein provided for relating to such transaction have been complied with.

SECTION 804. Successor Person Substituted for Guarantor.

Upon any consolidation or amalgamation of the Guarantor with or merger by the Guarantor into any other Person or any sale, lease, conveyance, transfer or other disposition of all or substantially all of the properties and assets of the Guarantor in accordance with Section 803, the successor Person formed by such consolidation or amalgamation or into which the Guarantor is merged or to which such sale, lease, conveyance, transfer or other disposition is made shall succeed to, and be substituted for, and may exercise every right and power of, the Guarantor under this Indenture with the same effect as if such successor Person had been named as the Guarantor herein and thereafter, except in the case of such lease, the predecessor Person shall be relieved of all obligations and covenants under this Indenture and the Guarantee.

2.6 Amendments to Article Ten of the Original Indenture (Covenants).

Article Ten of the Original Indenture is hereby amended in respect of, and applicable to, the Notes and only in respect of, and applicable to, the Notes by (a) amending and restating in their entirety Sections 1004 through 1006 as set forth below, and (b) adding thereto the following new Sections 1008 through 1010:

SECTION 1004. Existence.

Subject to Article Eight, each of the Company and the Guarantor will do or cause to be done all things necessary to preserve and keep in full force and effect its existence, whether corporate or otherwise.

SECTION 1005. Statement by Officers as to Default.

Each of the Company and the Guarantor will deliver to the Trustee, within 120 days after the end of each fiscal year ending after the date hereof so long as any Security is outstanding hereunder, an Officers’ Certificate, complying with Section 314(a)(4) of the Trust Indenture Act and stating that a review of the activities of the Company or the Guarantor, as applicable, during such year and of performance under this Indenture has been made under the supervision of the signers thereof and whether or not to the best of their knowledge, based upon such review, the Company or the Guarantor, as applicable, is in default in the performance, observance or fulfillment of any of its covenants and other obligations under this Indenture, and if the Company or Guarantor shall be in default, specifying each such default known to them and the nature and status thereof. One of the officers signing the Officers’ Certificate on behalf of the Guarantor delivered pursuant to this Section 1005 shall be the principal executive, financial or accounting officer of the Guarantor.

For purposes of this Section 1005, such compliance shall be determined without regard to any period of grace or requirement of notice provided under this Indenture.

SECTION 1006. Waiver of Certain Covenants.

The Company and the Guarantor may omit in any particular instance to comply with any covenant or condition set forth in Sections 1001 through 1005 and 1007 through 1010, inclusive, or any covenant added for the benefit of any series of Securities as contemplated by Section 301 (unless otherwise specified pursuant to Section 301) if before or after the time for such compliance the Holders of a majority in principal amount of the Outstanding Securities of all series affected by such omission (acting as one class) shall, by Act of such Holders, either waive such compliance in such instance or generally waive compliance with such covenant or condition, but no such waiver shall extend to or affect such covenant or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company or the Guarantor, as applicable, and the duties of the Trustee in respect of any such covenant or condition shall remain in full force and effect.

SECTION 1008. Limitations on Liens.

The Guarantor shall not, and shall not permit any of its Subsidiaries to, issue, assume or guarantee any Indebtedness for borrowed money secured by any Lien upon any Principal Property or any shares of stock or indebtedness of any

Subsidiary of the Guarantor that owns or leases a Principal Property (whether such Principal Property, shares of stock or indebtedness are now owned or hereafter acquired) without making effective provision whereby the Notes (together with, if the Guarantor shall so determine, any other Indebtedness or other obligation) shall be secured equally and ratably with (or, at the option of the Guarantor, prior to) the Indebtedness so secured for so long as such Indebtedness is so secured. The foregoing restrictions do not, however, apply to Indebtedness secured by Permitted Liens.

Notwithstanding the foregoing, the Guarantor and its Subsidiaries may, without securing the Notes, issue, assume or guarantee secured Indebtedness that would otherwise be subject to the foregoing restrictions in an aggregate principal amount that, together with all other such Indebtedness of the Guarantor and its Subsidiaries that would otherwise be subject to the foregoing restrictions (including Indebtedness permitted to be secured under clause (i) under the definition of Permitted Liens but excluding Indebtedness permitted to be secured under clauses (ii) through (xiv) thereunder) and the aggregate amount of Attributable Indebtedness deemed outstanding with respect to Sale/Leaseback Transactions (other than those in connection with which the Guarantor has voluntarily retired any of the Notes, any Pari Passu Indebtedness or any Funded Indebtedness pursuant to clause (c) of Section 1009 hereof), does not at any one time exceed 15% of the Guarantor’s Consolidated Net Tangible Assets.

SECTION 1009. Limitation on Sale/Leaseback Transactions.

The Guarantor shall not, and shall not permit any of its Subsidiaries to, enter into any Sale/Leaseback Transaction with any Person (other than the Guarantor or a Subsidiary of the Guarantor) unless: (a) the Guarantor or such Subsidiary would be entitled to incur Indebtedness in a principal amount equal to the Attributable Indebtedness with respect to such Sale/Leaseback Transaction secured by a Lien on the property subject to such Sale/Leaseback Transaction pursuant to Section 1008 hereof without equally and ratably securing the Notes pursuant to such covenant; (b) after the date of first issuance of the Notes hereunder and within a period commencing nine months prior to the consummation of such Sale/Leaseback Transaction and ending nine months after the consummation thereof, the Guarantor or such Subsidiary shall have expended for property used or to be used in the ordinary course of business of the Guarantor and its Subsidiaries an amount equal to all or a portion of the net proceeds of such Sale/Leaseback Transaction and the Guarantor shall have elected to designate such amount as a credit against such Sale/Leaseback Transaction (with any such amount not being so designated to be applied as set forth in clause (c) below or as otherwise permitted); or (c) the Company or the Guarantor, during the nine-month period after the effective date of such Sale/Leaseback Transaction, shall have applied to either (i) the voluntary defeasance or retirement of any Notes, any Pari Passu Indebtedness or any Funded Indebtedness or (ii) the acquisition of one or more Principal Properties at fair value, an amount equal to the greater of the net proceeds of the sale or transfer of the property leased in such Sale/Leaseback

Transaction and the fair value, as determined by the Guarantor Board of Directors, of such property as of the time of entering into such Sale/Leaseback Transaction (in either case adjusted to reflect the remaining term of the lease and any amount expended by the Guarantor as set forth in clause (b) above), less an amount equal to the sum of the principal amount of Notes hereunder, Pari Passu Indebtedness and Funded Indebtedness voluntarily defeased or retired by the Company or the Guarantor plus any amount expended to acquire any Principal Properties at fair value, within such nine-month period and not designated as a credit against any other Sale/Leaseback Transaction entered into by the Guarantor or any Subsidiary of the Guarantor during such period.

SECTION 1010. Change of Control Repurchase Event.

(a) Upon the occurrence of a Change of Control Repurchase Event with respect to the Notes, unless the Company has previously or concurrently exercised its right to redeem all of the Notes, each Holder of Notes will have the right, except as provided below, to require that the Company repurchase all or any part (in denominations of $2,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s Notes for a cash price equal to 101.0% of the aggregate principal amount of the Notes to be repurchased, plus accrued and unpaid interest, if any, thereon to the date of repurchase (the “Change of Control Payment”).

(b) Not later than 30 days following any Change of Control Repurchase Event, the Company will deliver, or cause to be delivered, to the Holders of record of the Notes, with a copy to the Trustee, a notice:

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

(2) offering to repurchase, pursuant to the procedures required by this Indenture and described in the notice (a “Change of Control Offer”), on a date specified in the notice, which shall be a Business Day not earlier than 30 days, nor later than 60 days, from the date the notice is delivered (the “Change of Control Payment Date”), and for the Change of Control Payment, all Notes that are properly tendered by such Holder pursuant to such Change of Control Offer prior to 5:00 p.m. New York time on the second Business Day preceding the Change of Control Payment Date; and

(3) describing the procedures, as determined by the Company, consistent with this Indenture, that Holders of record of the Notes must follow to accept the Change of Control Offer.

(c) On or before the Change of Control Payment Date, the Company will, to the extent lawful, deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of the Notes or portions of Notes properly tendered.

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

(1) accept for payment all Notes or portions of Notes (in denominations of $2,000 or integral multiples of $1,000 in excess thereof) properly tendered pursuant to the Change of Control Offer; and

(2) deliver or cause to be delivered to the Trustee 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.

(e) The Paying Agent will promptly deliver to each Holder who has so tendered Notes the Change of Control Payment for such Notes, and the Trustee will promptly authenticate 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 so tendered, if any; provided that each such new Note will be in a principal amount of $2,000 or integral multiples of $1,000 in excess thereof.

(f) 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, if any, 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 record date.

(g) A Change of Control Offer will be required to remain open for at least 20 Business Days or for such longer period as is required by law. The Company shall publicly announce the results of the Change of Control Offer on or as soon as practicable after the date of purchase.

(h) The Company shall not be required to make a Change of Control Offer upon a Change of Control Repurchase Event if (i) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer made by the Company and purchases all Notes properly tendered and not withdrawn under such Change of Control Offer or (ii) the Company has given notice of the redemption of all of the Notes then outstanding pursuant to paragraph 5 of the form of Notes included as Exhibit A hereto, unless and until there is a Default in the payment of the applicable redemption price.

(i) The Company shall comply with all applicable securities legislation in the United States, including, without limitation, the requirements of Rule 14e-1 under the Exchange Act and any other applicable laws and regulations in connection with the purchase of Notes pursuant to a Change of Control Offer. To the extent that the provisions of any applicable securities laws or regulations conflict with this Section 1010, the Company shall comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 1010 by virtue of such compliance.

(j) Notwithstanding anything to the contrary contained herein, a Change of Control Offer may be made in advance of a Change of Control Repurchase Event, conditional upon such Change of Control Repurchase Event, if a definitive agreement is in place for the Change of Control at the time of making of the Change of Control Offer.
