I think there is, and was reading this a while ago:
5.9 Form 8-K. At least five (5) days prior to Closing, Company shall prepare a draft Form 8-K announcing the Closing, together with, or incorporating by reference, the financial statements prepared by Company and its accountant, and such other information that may be required to be disclosed with respect to the Merger in any report or form to be filed with the SEC (“Merger Form 8-K”), which shall be in a form reasonably acceptable to Parent. Prior to Closing, Parent and Company will prepare the press release announcing the consummation of the Merger hereunder (“Press Release”). Simultaneously with the Closing, Parent shall file and distribute the Press Release. Within four (4) business days of the Closing, Parent shall file the Merger Form 8-K with the SEC.
