 legal counsel) that failing to so waive or provide consent would be inconsistent with the Kineta Board of Directors’ exercise of its fiduciary duties to the Company’s stockholders under applicable laws, and any waiver or consent so granted          
 shall not be deemed to be the encouragement, initiation or solicitation of an Acquisition Proposal;                                                                                                                                                      |
