VSE, an Alexandria engineering and management services company, discontinued its evaluation of strategic business alternatives, which had included a possible sale of the company. VSE said its board determined its shareholders would benefit more from the company's ongoing business plan than from the proposed alternatives. "Based on the announced contract awards received by VSE during the past several months and our decision to exit the telecommunications technologies market, we believe VSE has an opportunity to increase its revenues and profitability in its traditional business areas over the next two or three years," VSE chairman and chief executive Donald M.
