The Group Companies aggregate revenue falls below the threshold that would require any filings under Antitrust Laws. “Antitrust Laws” means laws and regulations in relation to monopolization restraints of trade and other aspects of competition that apply to the business and dealings of the Group Companies and the Investors (including their respective Affiliates) (as applicable), including, without limitation, the Sherman Act, Clayton Act and Hart-Scott-Rodino Antitrust Improvements Act in the United States, and the Antimonopoly Law of the PRC.
