F 061 Oct 2018 Octasic Mutual NDA_Standard.docx Confidential Page 1 of 3 This MUTUAL NON-DISCLOSURE AGREEMENT (the “Agreement”) is entered into and made effective as of the last date of signature hereto (the “Effective Date”) by and between: OCTASIC INC., on behalf of itself, its subsidiaries, and affiliates (“OCTASIC”) a company incorporated under the laws of Canada and having its principal place of business at 30-2901 Rachel E., Montreal, QC, H1W 4A4 Canada, phone 514-282-8858, and Company on behalf of itself, its subsidiaries, and affiliates (“COMPANY”) a company incorporated under the laws of ______________________________________________and having its principal place of business at: Address City, Province/State Country, Postal Code Website Phone Hereinafter referred to individually as the “Party” and collectively as the “Parties”. WHEREAS the Parties wish to assess the potential for entering into a business relationship (the "Purpose"), and desire to protect information each Party deems to be proprietary and/or confidential which may be disclosed by one Party (“Discloser”) to the other Party (“Recipient”) as necessary to facilitate said assessment. WHEREAS the Parties recognize that the Confidential Information (as defined in 2.) is a valuable asset of the Discloser and that misuse or unauthorized disclosure will substantially impair the value of the Confidential Information. NOW, THEREFORE, in consideration of the foregoing premises, the covenants, terms and conditions contained herein, and other good and valuable consideration, the Parties agree as follows: 1. This Agreement is to establish the basis for proper protection of Confidential Information disclosed. Any disclosure is at the discretion of Discloser, and nothing in this Agreement obligates either Party to make any particular disclosure of Confidential Information. This Agreement does not create any agency, joint venture, partnership or any other arrangement between the Parties. 2. The term “Confidential Information” means this Agreement and any information or data identified as confidential or proprietary disclosed in any form by Discloser to Recipient for or in connection with the Purpose, whether before or after the Effective Date and clearly identified as being proprietary and/or confidential or that by its nature and the circumstances of disclosure should reasonably be understood to be confidential, including, without limitation, know-how, technical information concerning the design, development and production of products, and commercial information concerning marketing, finance, pricing, operations and plans. Any Confidential Information disclosed verbally shall be designated as confidential at the time of disclosure and shall be confirmed in writing by Discloser within thirty (30) days; during such thirty (30) day period, such oral Confidential Information shall be provided the same protection under this Agreement as any other form of Confidential Information. 3. This Agreement may be terminated by either Party upon thirty (30) days written notice to the other Party, provided that the provisions of Sections 3, 4 and 5 hereof shall survive such expiration and any other obligations and rights which by their terms are intended to survive or be perpetual or irrevocable. 4. The standard of protection imposed on Recipient will be to the same degree of protection it uses to prevent disclosure of its own Confidential Information, but in no event any less than reasonable protection to prevent the Confidential Information from becoming available to the public. F 061 Oct 2018 Octasic Mutual NDA_Standard.docx Confidential Page 2 of 3 5. Recipient agrees: (1) – to use the Confidential Information only for the Purpose, (2) – to disclose the Confidential Information only to its employees, representatives, advisors and sub-contractors who have a need to know for the Purpose and who have agreed to be bound by the terms of this Agreement or similar terms, (3) – not to use the Confidential Information to reproduce, redesign, reverse engineer or manufacture any product or equipment of the Discloser, (4) keep the Confidential Information in a safe and secure place to prevent unauthorized use, access, dissemination, destruction, disclosure or loss, and (5) – to return all Confidential Information and all copies thereof in its possession to Discloser, or destroy them, promptly upon written request of Discloser or termination of this Agreement and promptly provide a written certificate confirming such destruction to the Discloser. 6. The obligations imposed by this Agreement will not apply to Confidential Information that, according to tangible and dated evidence: i) was already in, or subsequently comes into, the public domain through no breach of this Agreement by Recipient, provided however that Confidential Information shall not be deemed to be in the public domain merely because any part of such Confidential Information is embodied in general disclosures or because individual features, components or combinations thereof are now or become known to the public; ii) was received by Recipient from another source without restriction or breach of this Agreement when such source is not subject to a confidentiality obligation with Discloser; iii) was in the possession of Recipient prior to disclosure without restriction or breach of this Agreement; iv) was independently developed by or for the Recipient without use of the Confidential Information disclosed by Discloser under this Agreement; v) was or is disclosed pursuant to a judicial order or government decree or regulation provided, however, that the Recipient, to the extent possible, shall provide prompt written notice thereof to the Discloser in order to allow the Discloser to seek a protective order or to utilize other available procedures to protect such Confidential Information. Recipient agrees to provide reasonable assistance to Discloser in protecting such Confidential Information. …
