Invitation to prestigious New York conference is key step toward listing on major U.S. securities exchange

Los Angeles, CA — September 8, 2011 — OriginOil, Inc. (OOILD), the developer of a breakthrough technology to extract oil from algae and an emerging leader in the global algae oil services industry, today announced that Riggs Eckelberry, president and chief executive officer, will present a company overview at the Rodman & Renshaw Annual Global Investment Conference’s Cleantech Track on Tuesday, September 13, 2011, at 2:50 p.m. Eastern time (11:50 a.m. Pacific time) at the Waldorf Astoria Hotel in New York City (watch video) (view presentation).

“Rodman is one of the year’s most effective opportunities to present to institutional investors and analysts,” said Eckelberry. “As such, it represents another key step on our path toward listing on a major U.S. securities exchange.”

In a recent video, “OriginOil Scales Up in Australia,” the company reported on its rapid commercialization progress as a technology enabler to the fast-growing algae sector, which is showing increasing investment activity. In December of 2010, algae producer Martek was purchased for more than $1 billion in cash and taken private by nutrition conglomerate DSM. In May of 2011, algae company Solazyme raised total gross proceeds of more than $227 million in a high-profile IPO.

A webcast of CEO Eckelberry’s presentation will be available during the event on the Investors section of the company website at www.originoil.com and will be archived and available on the website for 90 days.
