WHEREAS, the Company may consolidate with or merge with or into any other Person or sell, convey, transfer or lease all or substantially all of its properties and assets to another Person subject to the provisions of Section 6.01 of the Indenture, and the Merger complies with the provisions of Section 6.01 of the Indenture;

WHEREAS, pursuant to the Merger Agreement and subject to the terms and conditions therein, at the effective time of the Merger (the “Effective Time”), each share of common stock, par value $0.001 per share, of the Company (the “Common Stock”) outstanding immediately prior to the Effective Time (other than shares of Common Stock held by (i) Parent, Merger Sub or the Company (as treasury stock or otherwise), or by any of their direct or indirect wholly owned subsidiaries immediately prior to the Effective Time, in each case other than shares of Common Stock held on behalf of third parties and (ii) stockholders who are entitled to demand and who properly and validly demand (and do not subsequently withdraw or fail to perfect) their statutory rights of appraisal in respect of such shares of Common Stock in compliance in all respects with applicable law) will be automatically converted into the right to receive $335.00 per share in cash, without interest and less any applicable withholding of taxes;

WHEREAS, the Merger constitutes a Merger Event, a Fundamental Change and a Make-Whole Fundamental Change under the Indenture;

WHEREAS, in connection with the foregoing, Section 4.07(a) of the Indenture provides that prior to or at the Effective Time, the Company will execute with the Trustee a supplemental indenture, without the consent of Holders as permitted by Section 10.01(g) and 10.01(h), providing that at and after the Effective Time, the right to convert each $1,000 principal amount of Notes shall be changed into a right to convert such principal amount of Notes into the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) that a holder of a number of shares of Common Stock equal to the Conversion Rate immediately prior to such Merger Event would have owned or been entitled to receive (the “Reference Property”, with each “unit of Reference Property” meaning the kind and amount of Reference Property that a holder of one share of Common Stock is entitled to receive) upon such Merger Event;

WHEREAS, Section 4.07 of the Indenture provides that if the holders of Common Stock receive only cash in a Merger Event, then for all conversions of Notes that occur after the Effective Time, (x) the consideration due upon conversion of each $1,000 principal amount of Notes shall be solely cash in an amount equal to the Conversion Rate in effect on the Conversion Date (as may be increased pursuant to Section 4.04), multiplied by the price paid per share of Common Stock in such Merger Event and (y) the Company shall satisfy the Conversion Obligation by paying cash to converting Holders on the second Business Day immediately following the relevant Conversion Date;

WHEREAS, all conditions for the execution and delivery of this First Supplemental Indenture have been complied with or have been done or performed; and

NOW THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged, the parties hereto mutually covenant and agree for the equal and ratable benefit of the Holders as follows:

DEFINITIONS

Section 1.01 Definitions.

For all purposes of this First Supplemental Indenture, except as otherwise herein expressly provided or unless the context otherwise requires: (i) the capitalized terms and expressions used herein shall have the same meanings as corresponding terms and expressions used in the Indenture and (ii) the words “herein,” “hereof” and “hereby” and other words of similar import used in this First Supplemental Indenture refer to this First Supplemental Indenture as a whole and not to any particular section hereof.

AMENDMENT OF INDENTURE

Section 2.01 Conversion of the Notes. In accordance with and subject to Sections 4.02(a) and 4.07 of the Indenture, as a result of the Merger, from and after the Effective Time, each $1,000 in principal amount of the Notes is convertible in accordance with the terms of the Indenture into Reference Property. As a result of the Merger, a Make-Whole Fundamental Change has occurred. Accordingly, a Holder who converts its Notes in connection with such Make-Whole Fundamental Change shall be entitled to receive Reference Property consisting of $1,293.23 in cash per $1,000 principal amount of Notes so converted (reflecting the requisite increase to the Conversion Rate pursuant to Section 4.04 of the Indenture). Thereafter, a Holder who converts its Notes during a period when such Notes are convertible in accordance with the terms of the Indenture shall be entitled to receive Reference Property consisting of $1,158.93 in cash per $1,000 principal amount of Notes. The provisions of the Indenture, as modified herein, shall continue to apply, mutatis mutandis, to the holders’ right to convert the Notes into the Reference Property.
