to, provide the other Party with a draft of such public announcement or press release at least seven (7) Business Days prior to the intended publication or announcement date for review and approval, which approval will not be unreasonably withheld or delayed, and shall incorporate any changes reasonably requested by such other Party. Both Parties shall not, and shall cause their respective Affiliates not to, directly or indirectly through any person disparage the other Party or any of its Affiliates in any way that could adversely affect the goodwill, reputation or business relationships of such Party or any of its Affiliates with the public generally, or with any of their distributors, customers, suppliers or employees.
