The Holder hereby makes the following representations and warranties, each of which is true and correct on the date hereof and the Closing Date and shall survive the Closing Date and the transactions contemplated hereby to the extent set forth herein.

Section 2.1 Existence and Power.

(a) The Holder is duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization and has the power, authority and capacity to execute and deliver this Agreement and the Letter of Transmittal, to perform its obligations hereunder and thereunder, and to consummate the transactions contemplated hereby.

(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.

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 Notes. The Holder has good and valid title to the Notes in the aggregate principal amount set forth on Schedule A, 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 Notes or its rights in such Notes, or (ii) given any person or entity (“Person”) any transfer order, power of attorney or other authority of any nature whatsoever with respect to such Notes which upon the Closing Date would limit the Holder’s power to transfer the Notes hereunder.

2

Section 2.4 Investment Decision. The Holder initially contacted the Company regarding the potential sale of the Notes. The Holder (or its authorized representative) has had the opportunity to review the Company’s filings with the Securities and Exchange Commission (the “Commission”), including, without limitation, the Company’s Annual Reports on Form 10-K for the year ended September 30, 2009 and for the year ended September 30, 2010, the Company’s Quarterly Reports on Form 10-Q for the quarters ended December 31, 2009, March 31, 2010 and June 30, 2010, the Company’s Proxy Statement filed January 11, 2010, and the Company’s Current Reports on Form 8-K filed on February 3, 2010, February 18, 2010, March 1, 2010, May 4, 2010, May 21, 2010, August 12, 2010, November 2, 2010 and November 12, 2010. The Holder has had such opportunity to ask questions of the Company and its representatives and to obtain from representatives of the Company such information as is necessary to permit it to evaluate the merits and risks of selling the Notes 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.

Section 2.5 Professional Advice. The Holder is knowledgeable, sophisticated and experienced in business and financial matters and has had the opportunity to consult with its accounting, tax, financial and legal advisors to be able to evaluate the risks involved in the Sale and to make an informed investment decision with respect to the Sale. With respect to the tax, accounting and other economic considerations involved in the Sale, the Holder is not relying on the Company or any of its affiliates, and the Holder has carefully considered and has, to the extent the Holder believes such discussion is necessary, discussed with the Holder’s professional legal, tax, accounting and financial advisors the implications of the Sale for the Holder’s particular tax, accounting and financial situation.

Section 2.6 Letter of Transmittal. The information provided by the Holder in the Letter of Transmittal in the form provided to the Holder is true and accurate as of the date hereof and the Holder shall advise the Company promptly of any changes therein on or prior to the Closing.

Section 3.3 Professional Advice. The Company is knowledgeable, sophisticated and experienced in business and financial matters and has had the opportunity to consult with its accounting, tax, financial and legal advisors to be able to evaluate the risks involved in the Sale and to make an informed investment decision with respect to the Sale. With respect to the tax, accounting and other economic considerations involved in the Sale, the Company is not relying on the Holder or any of its affiliates, and the Company has carefully considered and has, to the extent the Holder believes such discussion is necessary, discussed with the Company’s professional legal, tax, accounting and financial advisors the implications of the Sale for the Company’s particular tax, accounting and financial situation.
