The Brea deal is for 115,583 sf in an office building at 3151 E. Imperial Highway, while the Irvine lease is for an 8,348-sf bank branch at 2001 Michelson Dr.

Union Bank was represented in both deals by John Bosko and Robert Brandt of NAI Capital's Newport Beach office and the late David Powell of NAI Capital's Pasadena branch. The owner of the Brea building, Colyear Development Corp., was represented in-house by Jenni Suvari, while the Irvine Co. was represented in-house in the Irvine transaction.

Bosko tells GlobeSt.com that Union Bank has been in the 3151 E. Imperial Highway building as the sole tenant of the 115,583-sf office building since December 1998 in a 10-year lease. The bank renewed its lease early to lock in a favorable rate of $1.25 per sf per month triple net, at a flat rate for all 10 years.

The 3151 E. Imperial Highway building serves as a call center, training center for the bank. It also has 12,000 sf of space that is set up to serve as an emergency center for the bank in event of disaster, Bosko explains.

Union Bank has been in the 2001 Michelson Dr. building, which is in the Airport Area submarket, for approximately 20 years as the sole tenant in the building. Its previous lease was due to expire in December.
