Without limiting the foregoing, Licensee may not, and may not authorize or permit any other Person to, create derivative works of or otherwise modify any CSL Licensed IP without Licensor’s prior specific written consent in each instance.

8.1 The Parties agree that all information which is communicated from time to time by them to each other in connection with this Agreement (whether oral, electronic or written of any kind or nature), or which is confidential and proprietary to the person disclosing the same shall be deemed secret and confidential (“Confidential Information”). For clarity, as between the Parties, all CSL Licensed IP shall constitute Confidential Information of Licensor hereunder. The Parties agree that the Confidential Information received by them from the other will be maintained in confidence and that the same will not be disclosed to or used by any Person, firm, or undertaking except their own agents and employees, subcontractors or distributors hereunder who need to know and/or use such Confidential Information for the purposes of this Agreement.

Either Party must promptly inform the other Party of any information it believes comes within the circumstances in the immediately preceding sentence. Each Party will cooperate with the other Party, at the other Party’s expense, in seeking to maintain the confidentiality of such Confidential Information. Each Party’s obligations under this Section 8 shall survive the expiration or termination of this Agreement in perpetuity.

8.2 Nothing in this Section 8 shall require the recipient Party to hold in confidence or otherwise protect from unauthorized use of disclosure any information that: (i) is known to the recipient at the time of receipt (except, for clarity, with respect to any CSL Licensed IP that is known to Licensee as of the Effective Date); or (ii) is or becomes publicly available through no wrongful act of the recipient; or (iii) is rightfully received by the recipient from a third party without restriction and without breach of any agreement with the disclosing Party or any third party; or (iv) is independently developed by the recipient without breach of this Agreement or reference to the Confidential Information of the disclosing Party; or (v) is furnished by the disclosing Party to a third party without restriction.
