For purposes of this Agreement, “Confidential Information” will mean any information or knowledge, whether written or unwritten, other than Trade Secrets, which specifically relates to the Company’s business and finances and/or the Company’s affiliates, clients, vendors, distributors, and others with whom the Company does or has in the past done business, which the Company deems to be confidential and proprietary and which is generally not known to others outside the Company, regardless of when and by whom such information was developed or acquired, and regardless of whether any of these are described in writing, or are copyrightable, considered copyrightable, patentable or considered patentable. Confidential Information also specifically includes information or knowledge received by the Company from others, including its clients and affiliates, which the Company has an obligation to treat as confidential and also includes any confidential information acquired by Consultant while retained by the Company.

5. Restrictions on Use and Disclosure. Consultant will not, during the term of this Agreement or at any time thereafter, disclose, distribute, or publish or cause to be disclosed, distributed, or published in whole or in part any Confidential Information or Trade Secrets, to any person, firm, corporation, association, or any other operation or entity, except to employees or agents of the Company who are authorized by the Company to receive such information and then, only on behalf of the Company and only to the extent necessary in order for Consultant to perform faithfully his duties pursuant to this Agreement. Consultant further agrees that he will not at any time reproduce or permit the reproduction of any Confidential Information or Trade
