NOW, THEREFORE, it is mutually agreed as follows:

ARTICLE I

DEFINITIONS

SECTION 1.01. Definitions. For all purposes of this First Supplemental Indenture, except as otherwise expressly provided or unless the context otherwise requires:

“Change of Control” means the occurrence of any of the following: (1) the direct or indirect sale, transfer, conveyance or other disposition (other than by way of merger or consolidation), in one or a series of related transactions, of all or substantially all of the properties or assets of the Obligor and its Subsidiaries taken as a whole to any “person” (as that term is used in Section 13(d) and Section 14(d) of the Exchange Act) other than the Obligor or one of its Subsidiaries; (2) the adoption of a plan relating to the Obligor’s liquidation or dissolution; (3) the consummation of any transaction (including, without limitation, any merger or consolidation) the result of which is that any “person” (as that term is used in Section 13(d)(3) of the Exchange Act) or group of persons, other than the Obligor or its Subsidiaries, becomes the beneficial owner (as defined in Rules 13d-3 and 13d-5 of the Exchange Act), directly or indirectly, of more than 50% of the combined voting power of the Obligor’s Voting Stock or other Voting Stock into which the Obligor’s Voting Stock is reclassified, consolidated, exchanged or changed, measured by voting power rather than number of shares; or (4) the first day on which a majority of the members of the Board of Directors are not Continuing Directors.

“Change of Control Repurchase Event” means the occurrence of both a Change of Control and a Ratings Event.

“Comparable Treasury Issue” means the United States Treasury security selected by an Independent Investment Banker as having an actual or interpolated maturity comparable to the remaining term of the Senior Notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of such Senior Notes.

“Comparable Treasury Price” means, with respect to any Redemption Date, (1) the arithmetic average of four Reference Treasury Dealer Quotations for such Redemption Date after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) if the Trustee obtains fewer than four Reference Treasury Dealer Quotations, the arithmetic average of all Reference Treasury Dealer Quotations for such Redemption Date.

“Continuing Directors” means, as of any date of determination, any member of the Board of Directors who (1) was a member of the Board of Directors on the date of the issuance of the Senior Notes; or (2) was nominated for election or elected to the Board of Directors with the approval of a majority of the Continuing Directors who were members of the Board of Directors at the time of such nomination or election.

“First Supplemental Indenture” means this First Supplemental Indenture, as amended or supplemented from time to time.

“Fitch” means Fitch Ratings Ltd. and its successors.

“Independent Investment Banker” means Citigroup Global Markets Inc. or X.X. Xxxxxx Securities Inc., or their respective successors as may be appointed from time to time by the Obligor; provided, however, that if either of the foregoing ceases to be a primary U.S. Government securities dealer in New York City (a “primary treasury dealer”), the Obligor shall substitute another primary treasury dealer.

“Investment Grade” means a rating of BBB- or better by Fitch (or its equivalent under any successor rating categories of Fitch); a rating of Baa3 or better by Moody’s (or its equivalent under any successor Rating Categories of Moody’s); a rating of BBB- or better by S&P (or its equivalent under any successor Rating Categories of S&P); and the equivalent investment grade credit rating from any additional Rating Agency or Rating Agencies selected by the Obligor.

“Xxxxx’x” means Xxxxx’x Investors Service Inc. and its successors.

“Rating Agency” means (1) each of Fitch, Xxxxx’x and S&P; and (2) if any of Fitch, Moody’s or S&P ceases to rate the Senior Notes or fails to make a rating of the Senior Notes publicly available for reasons outside of the control of the Obligor, a “nationally recognized statistical rating organization” within the meaning of Rule 15c3-l(e)(2)(vi)(F) under the Exchange Act, selected by the Obligor (as certified by a resolution of the Board of Directors) as a replacement agency for Fitch, Moody’s or S&P, as the case may be.

“Rating Category” means (i) with respect to S&P, any of the following categories: XXX, XX, X, XXX, XX, X and D (or equivalent successor categories); (ii) with respect to Moody’s, any of the following categories: Baa, Ba, B, Caa, Ca, C and D (or equivalent successor categories); (iii) with respect to Fitch, any of the following categories: XXX, XX, X, XXX, XX, X and D (or equivalent successor categories); and (iv) the equivalent of any such category of S&P, Moody’s or Fitch used by another Rating Agency. In determining whether the rating of the Senior Notes has decreased by one or more gradations, gradations within Rating Categories (+ and - for S&P or Fitch; 1, 2 and 3 for Moody’s; or the equivalent gradations for another Rating Agency) shall be taken into account (e.g., with respect to S&P or Fitch, a decline in a rating from BB+ to BB, as well as from BB- to B+, shall constitute a decrease of one gradation).

“Ratings Event” means a decrease in the ratings of the Senior Notes by one or more of the Rating Agencies such that the Senior Notes are rated below Investment Grade by all of the Rating Agencies on any date from the date of the public notice of an arrangement that could result in a Change of Control until the end of the 60-day period following public notice of the occurrence of a Change of Control (which period shall be extended so long as the rating of the Senior Notes is under publicly announced consideration for possible downgrade by any of the Rating Agencies).

Notwithstanding the foregoing, a Ratings Event otherwise arising by virtue of a particular reduction in rating shall not be deemed to have occurred in respect of a particular Change of Control (and thus shall not be deemed a Ratings Event for purposes of the definition of Change of Control Repurchase Event hereunder) if the Rating Agencies making the reduction in rating to which this definition would otherwise apply do not announce or publicly confirm or inform the Trustee in writing at its request that the reduction was the result, in whole or in part, of any event or circumstance comprised of or arising as a

result of, or in respect of, the applicable Change of Control (whether or not the applicable Change of Control shall have occurred at the time of the Ratings Event).

“Reference Treasury Dealer” means Citigroup Global Markets Inc. and X.X. Xxxxxx Securities Inc., and two other primary treasury dealers selected by the Obligor, and each of their respective successors and any other primary treasury dealers selected by the Obligor.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any Redemption Date, the arithmetic average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Trustee by such Reference Treasury Dealer as of 5:00 p.m., New York City time, on the third Business Day preceding such Redemption Date.

“Remaining Scheduled Payments” means, with respect to any Senior Note to be redeemed, the remaining scheduled payments of the principal thereof and interest thereon that would be due after the related Redemption Date but for such redemption; provided, however, that, if such Redemption Date is not an Interest Payment Date with respect to such Senior Note, the amount of the next scheduled interest payment thereon shall be reduced by the amount of interest accrued thereon to such Redemption Date.

“Senior Notes” has the meaning assigned in the Recitals.

“S&P” means Standard & Poor’s Rating Services, a division of The XxXxxx-Xxxx Companies, Inc., and its successors.

“Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to the semi-annual equivalent yield to Maturity (computed as of the third Business Day immediately preceding that Redemption Date) of the Comparable Treasury Issue. In determining this rate, the Obligor shall assume a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date.

“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 generally in the election of the board of directors of such Person.

The terms of this Senior Note include those stated in the Indenture, and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. §§ 77aaa 77bbbb) as in effect on the date of the Indenture (the “TIA”). Terms defined in the Indenture and not defined herein have the meanings ascribed thereto in the Indenture.

14. Defaults and Remedies

If any Event of Default (other than an Event of Default relating to certain events of bankruptcy, insolvency or reorganization of the Company) with respect to this Senior Note occurs and is continuing, then either the Trustee or the Holders of not less than 25% in aggregate principal amount of the Outstanding Senior Notes may declare the principal of all Outstanding Senior Notes, and the interest to the date of acceleration, if any, accrued thereon, to be immediately due and payable by notice in writing to the Obligor (and to the Trustee if given by Holders) specifying the Event of Default. If an Event of Default relating to a merger or certain events of bankruptcy, insolvency or reorganization of the Company occurs, then the principal amount of all the Senior Notes then Outstanding and interest accrued thereon, if any, will become and be immediately due and payable without any declaration or other act on the part of the Trustee or the Holders of the Senior Notes, to the full extent permitted by applicable law.

Under certain circumstances, the Holders of a majority in principal amount of the Outstanding Senior Notes may rescind any such acceleration with respect to the Senior Notes and its consequences.

No Holder of this Senior Note may institute any action, unless and until: (i) such Holder has given the Trustee written notice of a continuing Event of Default with respect to the Senior Notes; (ii) the Holders of at least 25% in aggregate principal amount of the Outstanding Senior Notes have made a written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder; (iii) such Holder or Holders has or have offered the Trustee such reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request; (iv) the Trustee has failed to institute any such proceeding for 60 days after its receipt of such notice, request and offer of indemnity; and (v) no inconsistent direction has been given to the Trustee during such 60-day period by the Holders of a majority in aggregate principal amount of the Outstanding Senior Notes. These limitations do not apply to a suit instituted by a Holder of any Senior Notes for enforcement of payment of the principal of, and premium, if any, or interest on, such Senior Notes on or after the respective due dates expressed in such Senior Notes.

15. Trustee Dealings with the Obligor

Subject to certain limitations imposed by the TIA, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of this Senior Note and may otherwise deal with the Obligor with the same rights it would have if it were not Trustee.
