An agreement announced Thursday between Newport Beach-based aerospace consultant SM & A; and its founder ends a short but bitter proxy battle for control of the company's board. Under the terms, the company will replace two directors with ones selected from a pool recommended by major shareholders, including founder Steven Myers. The directors are set to be elected at the company's annual meeting Friday. Myers, who is the company's largest owner at 15%, also agreed to a standstill agreement that expires in 2010. Terms of the standstill agreement weren't disclosed. Such pacts usually prevent a shareholder from acquiring more stock or involve the company buying stock from the shareholder. In April, Myers and a group of supporters tried to take over the board after accusing the company's chief executive officer, Cathy McCarthy, of "inappropriate financial guidance" on conference calls, poor sales and handling of funds as well as losing key senior personnel.
