     4. Representations of the Buyer. The Buyer represents and warrants to the Holders as follows:

     (a) Organization. The Buyer is a corporation, duly organized, validly existing and in good standing under the laws of the State of Michigan, and is qualified to do business and in good standing in each jurisdiction where the character or location of its assets or properties owned, leased or operated by it or the nature of its activities makes such qualification necessary. The Buyer has full corporate power and authority and all material licenses, permits and authorizations necessary to own and operate its properties and to conduct its business as conducted.

     (b) Authority for Agreement. The Buyer has full power, authority and legal right to enter into and perform its obligations under this Agreement and to consummate the transactions contemplated hereby. The board of directors of the Buyer has duly approved this Agreement and the transactions contemplated hereby and have authorized the execution, delivery and performance of this Agreement and the consummation of the transactions contemplated hereby. No other proceedings on the part of the Buyer are necessary to approve and authorize the execution, delivery and performance of this Agreement and the consummation of the transactions contemplated hereby. This Agreement has been duly executed and delivered by the Buyer and is a legal, valid and binding obligation of the Buyer, enforceable against the Buyer in accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the enforcement of creditors’ rights in general.

     (c) No Violation to Result. The execution, delivery and performance by the Buyer of this Agreement and the consummation by the Buyer of the transactions contemplated hereby, do not and will not, directly or indirectly (with or without notice or lapse of time): (i) violate, breach, conflict with, constitute a default under, accelerate or permit the acceleration of the performance required by, (x) any of the terms of the Governing Documents of the Buyer or any resolution adopted by the directors or shareholders of the Buyer, or (y) any note, debt instrument, security agreement, mortgage or any other contract to which the Buyer is a party or by which it is bound; or (z) any law, judgment, decree, order, rule, regulation, permit, license or other legal requirement of any Government Authority applicable to the Buyer except to the extent the same would have

     (d) Brokers. No Person has or will have, as a result of the transactions contemplated by this Agreement, any right, interest or claim against or upon any of the Holders or the Buyer for any commission, fee or other compensation payable as a finder or broker because of any act or omission by the Buyer.

The Buyer acknowledges that the Warrants have not been, nor are they contemplated to be, registered under any federal, state or local securities laws, and may not be resold unless permitted under applicable exemptions contained in such securities laws or upon satisfaction of the registration or qualification requirements of such securities laws. The Buyer acknowledges and agrees that it must bear the economic risk of its investment in the Warrants for an indefinite period of time, since such investment has not been registered or qualified under such securities laws. The Buyer is not acquiring the Warrants with a view to, or for sale in connection with, any distribution thereof within the meaning of the Securities Act. Subject to its reliance on the express representations and warranties made by the Holders in this Agreement, the Buyer, together with its shareholders, directors and officers, is familiar with investments of the nature of the investment contemplated under this Agreement, understands that this investment involves substantial risks, has adequately investigated the Company and its business and has substantial knowledge and experience in financial and business matters, such that it is capable of evaluating, and has evaluated, the merits and risks inherent in purchasing the Warrants, and is able to bear the economic risks of such investment. Further, the Buyer agrees that it will truthfully and completely answer all questions, and make all covenants, that the Company may, contemporaneously or hereafter, reasonably ask or demand for the purpose of establishing compliance with the Securities Act and applicable state securities laws with respect to the Buyer’s purchase of the Warrants.

     (f) Acknowledgement Regarding Transaction. The Buyer represents that in making the decision to enter into this Agreement and consummate the transactions contemplated hereby, it has relied solely on its own independent investigation, the fairness opinion it caused to be prepared, the express representations, warranties, and covenants set forth in this Agreement and the Purchase Agreement, and the Buyer’s own assessment of the past, current, and future business, federal and state regulatory requirements, and operational requirements of the Company and its business. Accordingly, the Buyer acknowledges, represents and warrants that, except as expressly set forth in this Agreement and the Purchase Agreement, neither the Holders nor any officer, manager or employee of the Company has made, and the Buyer has not relied upon, any representations and warranties of any nature whatsoever.

     (g) Access to Data. The Buyer has had an opportunity to ask questions of, and receive answers from, the officers of the Company concerning the Company’s business, management and financial affairs, this Agreement, the Purchase Agreement, including the Schedules and Exhibits attached hereto and thereto, and the transactions contemplated hereby and thereby, which questions were answered to its satisfaction.

Nothing herein shall be deemed to prevent the Indemnified Party from making a claim, and an Indemnified Party may make a claim hereunder, for potential or contingent claims or demands; provided, the notice of such claim sets forth the basis for any such potential or contingent claim or demand to the extent then feasible and the Indemnified Party has reasonable grounds to believe that such a claim or demand may be made.

     (d) The Holders shall not be entitled to make any claim for indemnity or contribution or any similar claim against the Company or any of its Affiliates, with respect to any Losses for which the Holders are liable under Section 6 or this Section 8. To the extent that the Holders may now or in the future have the right to assert any such claim against the Company, the Holders hereby waive any such right and hereby release and forever discharge the Company from any such claim.
