Dear Mr. Fenton:

Confidentiality of Evaluation Materials: In connection with your consideration of a possible transaction involving Project 49er (the "Company") you have requested non-public information ("information") concerning the Company. As a condition to your being furnished with such Information, you agree to treat any Information concerning the Company which is furnished to you by or on behalf of the Company, whether furnished before or after the date of this letter and regardless of the manner in which it is furnished. together with analyses, compilations, studies or other documents or records prepared by you or any of your directors, officer, employees, affiliates, agents or advisors (including, without limitation, attorneys, accountants, consultants, financial advisors and any representatives of your advisors) (collectively, "Representatives") to the extent that such analyses, compilations, studies, documents or records contain or otherwise reflect or are generated from such Information (hereinafter collectively referred to as the "Evaluation Material"), in accordance with the provisions of this agreement. The term "Evaluation Material" does not include information which (i) was or becomes generally available to the public other than as a result of a disclosure by you or your Representatives, (ii) was or becomes available to you on a non-confidential basis from a source other than the Company or its advisors provided that such source is not known to you to be bound by a confidentiality agreement with the Company or otherwise prohibited from transmitting the information to you by a contractual, legal or fiduciary obligation, (iii) was within your possession prior to its being furnished to you by or on behalf of the Company provided that to your knowledge, the source of such information was not bound by a confidentiality agreement with the Company or otherwise prohibited from transmitting the information to you by a contractual, legal or fiduciary obligation, or (iv) was independently developed by you or your Representatives without reference to the Evaluation Material. Any combination of Information shall not be deemed to be within the foregoing exceptions because individual features of the Information are in the public domain.

Restrictions on Disclosure and Use: You hereby agree that the Evaluation Material will be used solely for the purpose of evaluating or implementing a possible transaction between the Company and you. and that such Evaluation Material will be kept confidential by you and your Representatives; provided, however, that (a) such Evaluation Material may be disclosed to your Representatives who need to know such information for the purpose of evaluating any such possible transaction between the Company and you (it being understood that such Representatives shall have been informed by you of the confidential and proprietary nature of the Evaluation Material, advised of this agreement and shall have an obligation to keep confidential the Evaluation Material), and (b) any disclosure of such Evaluation Material to a third party other than your Representative may be made to which the Company consents in writing prior to disclosure. In any event, you shall be responsible for any breach of this agreement by any of your Representatives and you agree, at your sole expense, to take all reasonable measures (including but not limited to court proceedings) to restrain your Representatives from prohibited or unauthorized disclosure or use of the Evaluation Material. You further agree that the Evaluation Material that is in written form shall not be copied or reproduced at any time without the prior written consent of the Company, except for distribution to your Representatives in accordance with and subject to the provisions of this agreement.

In addition, without the prior written consent of the Company, you will not, and will direct your Representatives not to, disclose to any person (i) the existence of this agreement and that the Evaluation Material has been made available to you or your Representatives, (ii) that discussions or negotiations are taking place concerning a possible transaction between the Company and you or (iii) any terms, conditions or other facts with respect to any such possible transaction, including the status thereof. The Company may not, and will direct its Representatives not to, disclose to any person that discussions or negotiations are taking place concerning a possible transaction between you and the Company unless required by law.

In the event that you are requested or required (by oral questions, interrogatories, requests for information or documents, subpoena, civil investigative demand or other process) to disclose any Evaluation Material, it is agreed that you will provide the Company with prompt notice of any such request or requirement (written if practical) so that the Company may, at its expense, seek an appropriate protective order or waive your compliance with the provisions of this agreement. If, failing the entry of a protective order or the receipt of a waiver hereunder, you are, after consultation with the Company and after providing the Company with written opinion of legal counsel to that effect, legally compelled to disclose Evaluation Material, you may disclose only that portion of the Evaluation Material which you are legally compelled to disclose and will exercise reasonable efforts to obtain assurance that confidential treatment will be accorded to that portion of the Evaluation Material which is being disclosed. In any event, you will not oppose action by the Company to obtain an appropriate protective order or other reliable assurance that confidential treatment will be accorded the Evaluation Material.

Non-Solicitation: You agree not to, and will cause your Representatives not to, initiate or maintain contact (except for those contacts made in the ordinary course of business) in connection with a potential transaction between you and the Company with any officer, director or employee of the Company or any other third party with whom the Company has a business relationship (including customers or suppliers) regarding the Company's business, operations, prospects or finances, except with the express written permission of the Company.
