Dear Mr. Kalanick, Mr. Graves and Mr. Camp: We represent Shervin Pishevar and Steve Russell, individually, jointly and as putative class representatives on behalf of several hundred Uber employees and other prominent investors who will suffer billions of dollars in damages (exclusive of penalties and punitive damages) if you support the covert effort, apparently led by Benchmark, to strip Class B Common stock holders of their voting rights.
