The deal will provide Oaktree Capital Management, which already occupies 75,000 sf at Wells Fargo Center, with an additional 25,000 sf. The high-rise stands at 333 S. Grand Ave. in the Bunker Hill area.

The lease expansion runs through April 2009 and is valued at about $5.4 million. Oaktree Capital was represented by Stephen L. Bay and Clay Hammerstein, a brokerage team in the Downtown office of Insignia/ESG that has handled several other Oaktree-related deals in the past. The building's owner, Downtown-based Maguire Partners, was represented in-house by Josh Wrobel and Tony Morales.

Oaktree Capital has been involved in several high-profile investments over the past several months. Just a few weeks ago, it became a minority partner in the venerable but bankrupt Edwards Theatres chain of movie houses by helping Denver billionaire Philip F. Anschutz take control of the Newport Beach-based chain through a deal involving more than $250 million in cash, debt and stock.
