2.                                      All information about the Company or any third party that is furnished by the Company or its Representatives (as defined below) to Prescott before the date hereof, now or in the future, and regardless of the manner in which it is furnished, is referred to in this letter agreement as “Proprietary Information”.  Proprietary Information does not include, however, any information that (i) is or becomes generally available to the public other than as a result of a disclosure by Prescott, any of its Affiliates or any of their respective Representatives in violation of this letter agreement; (ii) was available to Prescott, any of its Affiliates or any of their respective Representatives on a non-confidential basis prior to its disclosure by the Company or its Representatives; (iii) becomes available to Prescott, any of its Affiliates or any of their respective Representatives from a person other than the Company or its Representatives who is not subject to any legally binding obligation to keep such information confidential; or (iv) was independently developed by Prescott, any of its Affiliates or any of their respective Representatives without reference to or use of the Proprietary Information.  For purposes of this letter agreement, (x) “Affiliates” of Prescott shall mean (A) Prescott Group Aggressive Small Cap, L.P., (B) Prescott Group Aggressive Small Cap II, L.P,

3.                                      Subject to paragraph 4 below, unless otherwise agreed to in writing by the Company, Prescott shall, (i) except as required by law, keep all Proprietary Information confidential and not disclose or reveal any Proprietary Information to any person (other than to its Affiliates, its Representatives and Representatives of its Affiliates who have a need to know such information for purposes of assisting in Prescott’s evaluation of the Company, provided that each such Affiliate and Representative shall keep confidential all Proprietary Information that is so disclosed or revealed to him or her in accordance with Prescott’s confidentiality obligations hereunder with respect to such Proprietary Information); (ii) not use Proprietary Information for any purpose other than enabling Prescott to make non-publicly disclosed suggestions to the Board regarding the Company’s ongoing business and corporate strategies and policies; and (iii) except as required by law or legal process, not disclose to any person the fact that Proprietary Information has been disclosed to Prescott, provided that, for the avoidance of doubt, the disclosure of the existence of this letter agreement and the filing of this letter agreement as an exhibit to any Schedule 13D or amendment thereto shall not be deemed to be a breach of the foregoing clause (iii).  Prescott will be responsible for any violation of the confidentiality provisions of this letter agreement by its Affiliates, its Representatives and the Representatives of its Affiliates as if they were parties hereto.  The obligations of Prescott contained in this paragraph 3 to keep Proprietary Information confidential shall survive any termination or expiration of this letter agreement solely for a period of 18 months from and after such termination or expiration.

4.                                      In the event that Prescott, any of its Affiliates or any of their respective Representatives is requested pursuant to, or required by, applicable law or regulation (including, without limitation, any rule, regulation or policy statement of any national securities exchange, market or automated quotation system applicable to Prescott or any of its Affiliates) or by legal process to disclose any Proprietary Information, Prescott shall provide the Company with prompt notice of such request or requirement in order to enable the Company (i) to seek an appropriate protective order or other remedy, (ii) to consult with Prescott with respect to the Company’s taking steps to resist or narrow the scope of such request or legal process or (iii) to waive compliance, in whole or in part, with the terms of this letter agreement.  In the event that such protective order or other remedy is not timely sought or obtained, or the Company waives compliance, in whole or in part, with the terms of this letter agreement, Prescott shall (x) use commercially reasonable efforts to disclose only that portion of the Proprietary Information which is, in the opinion of outside legal counsel, legally required to be disclosed and to ensure that all Proprietary Information that is so disclosed will be accorded confidential treatment and (y) provide the Company with the text of such required disclosure as far in advance of its disclosure as reasonably practicable and consider in good faith the Company’s suggestions concerning the nature and scope of the information to be contained therein.  In the event that Prescott shall have complied, in all material respects, with the provisions

2

of this paragraph 4, such disclosure may be made by Prescott, such Affiliate or such Representative, as applicable, without any liability hereunder.

6.                                      Notwithstanding anything to the contrary herein, Prescott may, in its sole discretion, terminate the provisions of paragraph 5 of this letter agreement (including all restrictions thereunder on the activities in which Prescott, its Affiliates and other persons affiliated with Prescott may engage with respect to the Company) by delivering written notice of such termination to the Company at any time after the approval by the Board of:

10.                               Prescott is aware of the restrictions imposed by the United States securities laws on the purchase or sale of securities by any person who has received material, non-public information from the issuer of such securities and on the communication of such information to any other person when it is reasonably foreseeable that such other person is likely to purchase or sell such securities in reliance upon such information.
