(b) The execution of this Agreement by the Holder and the consummation by the Holder of the transactions contemplated hereby do not and will not constitute or result in a breach, violation, conflict or default under any note, bond, mortgage, deed, indenture, lien, instrument, contract, agreement, lease or license to which the Holder is a party, whether written or oral, express or implied, or any statute, law, ordinance, decree, order, injunction, rule, directive, judgment or regulation of any court, administrative or regulatory body, governmental authority, arbitrator, mediator or similar body on the part of the Holder or on the part of any other party thereto or cause the acceleration or termination of any obligation or right of the Holder, except for such breaches, conflicts, defaults, rights or violations which would not, individually or in the aggregate, reasonably be expected to have a material adverse effect on the ability of the Holder to perform its obligations hereunder.

- 4 -

Section 2.2 Valid and Enforceable Agreement; Authorization. This Agreement has been duly executed and delivered by the Holder and constitutes a legal, valid and binding obligation of the Holder, enforceable against the Holder in accordance with its terms, except that such enforcement may be subject to (a) bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting or relating to enforcement of creditors’ rights generally, and (b) general principles of equity.

Section 2.3 Title to Outstanding Notes. The Holder is the sole beneficial owner of and has good and valid title to the Outstanding Notes being exchanged by such Holder hereby, free and clear of any mortgage, lien, pledge, charge, security interest, encumbrance, title retention agreement, option, equity or other adverse claim thereto. The Holder has not, in whole or in part, (i) assigned, transferred, hypothecated, pledged or otherwise disposed of the Outstanding Notes or its rights in such Outstanding Notes being exchanged or redeemed by such Holder hereby, or (ii) given any person or entity any transfer order, power of attorney or other authority of any nature whatsoever with respect to such Outstanding Notes.

Section 2.4 Investment Decision. The Holder is either (i) a “qualified institutional buyer” within the meaning of Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”) or (ii) an “accredited investor” within the meaning of Rule 501 of Regulation D under the Securities Act, and in either case was not organized for the purpose of acquiring the 3.5% Notes or the shares of the Company’s common stock (the “Common Stock”), $0.001 par value per share, into which the 3.5% Notes may be converted (the “Underlying Common Stock”). The Holder (or its authorized representative) is familiar with the Company’s objectives and business plan, has had the opportunity to review the Company’s filings with the Securities and Exchange Commission (the “SEC”), including, without limitation, the Company’s Annual Report on Form 10-K filed on January 17, 2006, the Company’s Quarterly Reports on Form 10-Q filed on each of March 10, 2006, June 9, 2006 and September 11, 2006, the Company’s Definitive Proxy Statement filed on February 24, 2006, and the Company’s Current Reports on Form 8-K filed on March 2, 2006, March 21, 2006, March 25, 2006, May 25, 2006, August 9, 2006, August 24, 2006, September 11, 2006, November 13, 2006, December 7, 2006 and December 8, 2006 and the Company’s Amended Current Report on Form 8-K/A filed on December 8, 2006 (all of such filings with the SEC referred to, collectively, as the “SEC Documents”). The Holder has reviewed copies of each of the Indenture and the Registration Rights Agreement, including copies of each of the Indenture and Registration Rights Agreement marked to show the differences between such documents and the respective indenture and registration rights agreement related to the Outstanding Notes, and has had an opportunity to ask questions of the Company and to obtain from representatives of the Company such information as is necessary to determine the changes reflected in each such document, including the changes to the terms of the 3.5% Notes compared with the Outstanding Notes. The Holder has had such opportunity to ask questions of the Company and its representative and to obtain from representatives of the Company such information as is necessary to permit it to evaluate the merits and risks of its investment in the Company and has independently, without reliance upon any representatives of the Company and based on such information as the Holder deemed appropriate, made its own analysis and decision to enter into this Agreement. The Holder has had the opportunity to consult with its accounting, tax, financial and legal advisors to be able to evaluate the risks involved in the exchange of the Outstanding Notes pursuant hereto and to make an informed investment decision with respect to such exchange. The Holder acknowledges

- 5 -

that the Company is relying on the truth and accuracy of the foregoing representations and warranties in the offering of the 3.5% Notes to the Holder without having first registered the 3.5% Notes or the Underlying Common Stock under the Securities Act.

Section 2.5 Purchase Entirely for Own Account. The Holder is acquiring the 3.5% Notes for its own account and not towards, or for resale in connection with, the public sale or distribution thereof, except pursuant to sales registered or exempted under the Securities Act; provided, however that by making the representations herein, the Holder does not agree to hold any of such 3.5% Notes for any minimum or other specific term and reserves the right to dispose of such 3.5% Notes or the Underlying Common Stock at any time in accordance with or pursuant to a registration statement or an exemption under the Securities Act and pursuant to the applicable terms of this Agreement. The Holder is acquiring the 3.5% Notes to be issued to the Holder hereunder in the ordinary course of its business. The Holder does not presently have any understanding, directly or indirectly, with any person to distribute any of the 3.5% Notes to be issued to the Holder hereunder.

Section 2.6 Restricted Securities. The Holder understands that neither the 3.5% Notes nor the Underlying Common Stock have been registered under the Securities Act, and are being issued hereunder by reason of a specific exemption from the registration provisions of the Securities Act which depends upon, among other things, the bona fide nature of the investment intent and the accuracy of the Holder’s representations as expressed herein. The Holder understands that the 3.5% Notes (and the Underlying Common Stock) are “restricted securities” under applicable U.S. federal and state securities laws and that, pursuant to these laws, the Holder must hold the 3.5% Notes (and the Underlying Common Stock) indefinitely unless they are registered with the SEC and qualified by state authorities, or an exemption from such registration and qualification requirements is available. The Holder further acknowledges that if an exemption from registration or qualification is available, it may be conditioned on various requirements including, but not limited to, the time and manner of sale, the holding period for the 3.5% Notes (and the Underlying Common Stock), and on requirements relating to the Company which may be outside the Holder’s control, and which, except as set forth in the Registration Rights Agreement, the Company is under no obligation and may not be able to satisfy.

Section 2.7 No Public Market. The Holder understands that no public market now exists for the 3.5% Notes, and that the Company has made no assurance that a public market will ever exist for the 3.5% Notes.

Section 2.8 Legends. The Holder understands that the 3.5% Notes and any shares of Underlying Common Stock will bear one or more of the legends required by the Indenture, and the removal of such legends shall be governed by the terms of the Indenture.

Section 2.9 Affiliate Status. The Holder is not, and has not been during the preceding three months, an “affiliate” of the Company as such term is defined in Rule 144 under the Securities Act.
