Each party shall use and protect the Confidential Information of the other party in accordance with the terms of this Agreement.

2. Definition of Confidential Information. “Confidential Information” means any information, technical data, or know-how, including, but not limited to, that which relates to trade secrets, know-how, proprietary information, techniques, research, product plans, products, services, customer information, software, developments, inventions, processes, designs, drawings, engineering information, hardware configuration information, marketing and financial information disclosed by one party (“Disclosing Party”) to the other party (“Recipient”).

Confidential Information does not include information that: (i) was in the public domain through no fault of the Recipient at or subsequent to the time such information was disclosed by the Disclosing Party, (ii) was rightfully in the Recipient’s possession free of any obligation of confidence at or subsequent to the time such portion was disclosed by the Disclosing Party, (iii) was developed by employees or agents of the Recipient independently of and without reference to the Disclosing Party’s Confidential Information, or (iv) is a general concept, technique, or element of know-how. The Recipient may disclose Confidential Information of the Disclosing Party (x) in response to a valid order by a court or other governmental body, (y) as required by law, or (z) as necessary to establish the rights of either party under this Agreement; provided, however, the Recipient shall notify the Disclosing Party promptly of its intention to make such disclosures to enable the Disclosing Party to seek a protective order or otherwise attempt to prevent such disclosure.

3. Non-Disclosure of Confidential Information. Recipient shall not (i) use any Confidential Information of the Disclosing Party other than to further the Purpose, or (ii) disclose any Confidential Information of the Disclosing Party to any third party except as provided below in this paragraph. Furthermore, the existence of any business negotiations, discussions, consultations or agreements between the parties shall not be disclosed to any third without written approval of both parties. Recipient shall protect all Confidential Information of the Disclosing Party with the same degree of care the Recipient uses to protect its own Confidential Information, but in no event with less than reasonable care. Recipient may disclose Confidential Information of the Disclosing Party only to those of the Recipient’s employees, its Affiliates or its contractors who need to know such information for the purpose of evaluating the Purpose, provided that any such employee, Affiliate or contractor be bound to Recipient by an obligation of confidentiality and the Recipient will require such employees, and contractors to abide by the terms and conditions of this Agreement with respect to the Disclosing Party’s Confidential Information. For the purpose of this Agreement, “Affiliate” shall mean any entity or company which directly or indirectly, through one or more intermediaries, controls, is controlled by or is under common control with a party.

4. Return of Materials. Any materials or documents in the Recipient’s possession or control that contain Confidential Information of the Disclosing Party shall be promptly returned by the Recipient within 30 days after (i) the Purpose has been terminated and (ii) the written request of the Disclosing Party.

All materials (including, without limitation, documents, drawings, models, apparatus, sketches, designs, lists and all other tangible media of expression) furnished by each of the parties, as Disclosing Party, to the other party, as Recipient, shall remain the property of such Disclosing Party.
