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 each Holder and the consummation by each 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 each 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 each Holder or on the part of any other party thereto or cause the acceleration or termination of any obligation or right of each 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 each Holder to perform its obligations hereunder.

Section 2.2                                      Valid and Enforceable Agreement; Authorization.  This Agreement has been duly executed and delivered by each Holder and constitutes a legal, valid and binding obligation of the Holder, enforceable against each 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.  Each 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.

Section 2.4                                      Investment Decision.  Each 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 Report on Form 10-K for the year ended September 30, 2012, the Company’s Quarterly Reports on Form 10-Q for the quarters ended December 31, 2012 and March 31, 2013, the Company’s Proxy Statement filed January 7, 2013, and the Company’s Current Reports on Form 8-K filed on December 26, 2012, January 29, 2013, February 22, 2013, and April 30, 2013.  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.
