b.	Information.  Such Investor and its advisors, if any, have been furnished with all materials relating to the business, finances and operations of the Company and materials relating to the offer and sale of the Common Shares which have been requested by such Investor.  Such Investor and its advisors, if any, have been afforded the opportunity to ask questions of the Company.

c.	Transfer or Resale.  Such Investor understands that except as provided in the Registration Rights Agreement:  (i) the Common Shares have not been and are not being registered under the Securities Act or any state securities laws, and may not be offered for sale, sold, assigned or transferred unless subsequently registered thereunder or such Investor provides the Company with reasonable assurance that such Common Shares can be sold, assigned or transferred pursuant to Rule 144 promulgated under the Securities Act (or a successor rule thereto) ("Rule 144") or other applicable exemption from registration under the Securities Act; (ii) any sale of the Common Shares made in reliance on Rule 144 may be made only in accordance with the terms of Rule 144 and further, if Rule 144 is not applicable, any resale of the Common Shares under circumstances in which the seller (or the person through whom the sale is made) may be deemed to be an underwriter (as that term is defined in the Securities Act) may require compliance with some other exemption under the Securities Act or the rules and regulations of the SEC thereunder; and (iii) neither the Company nor any other person is under any obligation to register such Common Shares under the Securities Act or any state securities laws or to comply with the terms and conditions of any exemption thereunder.

|j.	Termination.  In the event that the Closing shall not have occurred on or before three (3) Business Days from the date hereof due to the Company's or the Investor's failure to satisfy one or more of the conditions set forth in Sections 5 and 6 above (and the non-breaching party's failure to waive such unsatisfied condition(s)), the non-breaching party shall have the option to terminate this Agreement with respect to such breaching party at the close of business on such date without liability of any party to any other party.

The Company shall pay, and hold each Investor harmless against, any liability, loss or expense (including, without limitation, reasonable attorneys' fees and out of pocket expenses) arising in connection with any such claim.

l.	Remedies.  Each Investor and each holder of the Common Shares shall have all rights and remedies set forth in the Transaction Documents and all rights and remedies which such holders have been granted at any time under any other agreement or contract and all of the rights which such holders have under any law.  Any person having any rights under any provision of this Agreement shall be entitled to enforce such rights specifically (without posting a bond or other security), to recover damages by reason of any breach of any provision of this Agreement and to exercise all other rights granted by law.

IN WITNESS WHEREOF, the Investors and the Company have caused this Exchange and Amendment Agreement to be duly executed as of the date first written above.
