Flags of models produced by General Motors are seen in front of a car dealer's store in Zagreb June 2, 2009. General Motors said on Tuesday that it had entered into a memorandum of understanding to sell its Hummer brand, but didn't name the buyer or say how much money it would get for the all-SUV line. GM, which filed for bankruptcy on Monday, said the sale was is set to close by the third quarter of this year and should secure more than 3,000 jobs in manufacturing, engineering and at Hummer dealerships around the United States.
