7.1 Confidentiality. Except to the extent expressly authorized by this Agreement or otherwise agreed in writing by the Parties, the Parties agree that, during the Term and for ten (10) years thereafter, the receiving Party shall keep confidential and shall not publish or otherwise disclose and shall not use for any purpose other than as expressly provided for in this Agreement any Confidential Information of the other Party, and both Parties shall keep confidential and, subject to Sections 7.2, 7.3 and 7.5, shall not publish or otherwise disclose the terms of this Agreement. Each Party may use the other Party’s Confidential Information only to the extent required to accomplish the purposes of this Agreement, including exercising its rights or performing its obligations. Each Party will use at least the same standard of care as it uses to protect proprietary or confidential information of its own (but no less than reasonable care) to ensure that its employees, agents, consultants, contractors and other representatives do not disclose or make any unauthorized use of the Confidential Information of the other Party. Each Party will promptly notify the other upon discovery of any unauthorized use or disclosure of the Confidential Information of the other Party.

7.2 Exceptions. Notwithstanding anything to the contrary in this Agreement, Confidential Information shall not include any information that the receiving Party can prove by competent written evidence: (a) is now, or hereafter becomes, through no act or failure to act on the part of the receiving Party, generally known or available to the public; (b) is known by the receiving Party at the time of receiving such information, other than by previous disclosure of the disclosing Party, or its Affiliates, employees, agents, consultants or contractors; (c) is hereafter furnished to the receiving Party without restriction by a Third Party who has no obligation of confidentiality or limitations on use with respect thereto, as a matter of right; or (d) is independently discovered or developed by the receiving Party without the use of Confidential Information belonging to the disclosing Party. Notwithstanding anything to the contrary in this Agreement, a receiving Party shall not be liable to the disclosing Party for the use of Residuals (defined below) from Confidential Information of the disclosing Party, provided that the receiving Party no longer has use of or access to any embodiment of such Confidential Information. This right to Residuals does not represent a license under any patents, trade secret rights, copyrights or other intellectual property rights of the disclosing Party. The term “Residuals” means any information that is retained in the unaided memories of the receiving Party’s employees who have had access to the disclosing Party’s Confidential Information pursuant to the terms of this Agreement and who does not and cannot identify such information as the Confidential Information of the disclosing Party.

7.4 Publication. CG shall not publish peer reviewed manuscripts, or provide other forms of public disclosure, including abstracts and presentations, of results of studies or activities with respect to any Licensed Compound or Product in the Licensed Territory without the prior written consent of Aptose, which shall not be unreasonably withheld.

It is understood that each Party may desire or be required to issue subsequent press releases relating to this Agreement or activities hereunder. The Parties agree to consult with each other reasonably and in good faith with respect to the text and timing of such press releases prior to the issuance thereof, to the extent practicable, provided that a Party may not unreasonably withhold, condition or delay consent to such releases, and that either Party may issue such press releases or make such disclosures as it determines, based on advice of counsel, are reasonably necessary to comply with Applicable Laws, including regulations applicable to the public sale of securities, or for appropriate market disclosure. Each Party shall provide the other Party with advance notice of legally required disclosures to the extent practicable. The Parties will consult with each other on the provisions of this Agreement to be redacted in any public filings made by a Party as otherwise required by Applicable Laws; provided that each Party shall have the right to make any such filing as it reasonably determines necessary under Applicable Laws. In addition, following the initial joint press release announcing this Agreement, either Party shall be free to disclose, without the other Party’s prior written consent, the existence of this Agreement, the identity of the other Party and those terms of the Agreement that have already been publicly disclosed in accordance herewith.

7.6 Equitable Relief. Given the nature of the Confidential Information and the competitive damage that a Party would suffer upon unauthorized disclosure, use or transfer of its Confidential Information to any Third Party, the Parties agree that monetary damages may not be a sufficient remedy for any breach of this Article 7. In addition to all other remedies, a Party shall be entitled to seek specific performance and injunctive and other equitable relief as a remedy for any breach or threatened breach of this Article 7.

If as to any issue the arbitrators should determine under Applicable Laws that the position taken by a Party is frivolous or otherwise irresponsible or that any wrongdoing it finds is in callous disregard of law and equity or the rights of the other Party, the arbitrators shall also be entitled to award an appropriate allocation of the adversary’s reasonable attorneys’ fees, costs and expenses to be paid by the offending Party, the precise sums to be determined after a xxxx of attorneys’ fees, expenses and costs consistent with such award has been presented following the award on the merits.

Additionally, nothing in this Article 11 will preclude either Party from seeking equitable relief or interim or provisional relief from a court of competent jurisdiction, including a temporary restraining order, preliminary injunction or other interim equitable relief, concerning a dispute either prior to or during any arbitration if necessary to protect the interests of such Party or to preserve the status quo pending the arbitration proceeding.
