Unocal Corp. Move Likely: The oil giant is expected to sign a lease today for a 12-story Costa Mesa building where it will move 700 employees and the headquarters of a key division. After several months of negotiations, the Los Angeles company’s marketing and refining arm, 76 Products Co., will sign a 10-year lease for the Bank of America building near South Coast Plaza. Lawrence M. Higby, president of 76 Products, said voter rejection of a sales tax increase Tuesday did not affect his company’s decision to move and that he does not expect Orange County’s fiscal woes to hurt the company’s ability to attract quality workers.
