THUNDER FACTORY Named Direct Response
Agency for Extra Space Storage�

Will Develop Performance-Driven Marketing Campaigns to Build Extra Space Storage Brand and Expand Market Share for Leading Self Storage Company

SAN FRANCISCO – August 15, 2006 – THUNDER FACTORY, the fast-growing integrated marketing firm that delivers performance-driven marketing results to blue-chip clients worldwide, today announced that it has been chosen by Extra Space Storage as its direct response firm. Extra Space Storage, based in Salt Lake City, Utah (NYSE: EXR), is the second largest self storage provider in the U.S.

Extra Space Storage is looking to build on its recent acquisition of Storage USA to create a more compelling and differentiated experience and brand promise for its customers. It is partnering with THUNDER FACTORY to develop and execute integrated marketing strategies to achieve its ambitious marketing and business expansion goals. THUNDER FACTORY's first task will be to develop a more robust strategic marketing plan, initially focusing on direct marketing (both online and offline). The self storage industry is very fragmented and not dominated by any one major brand, a fact which THUNDER FACTORY plans to exploit in its integrated marketing programs to drive Extra Space Storage's business.

�We selected THUNDER FACTORY after a close review of several marketing agencies. We were really impressed with their creativity and their overall understanding of our business,� said Buck Brown, Senior Vice President of Marketing for Extra Space Storage. �THUNDER FACTORY subscribes to a results-focused integrated marketing model that is all about helping us grow. We look forward to a productive partnership with them.�

�We pride ourselves on working with strong leadership brands and Extra Space Storage is exactly that, a leader in a rapidly growing U.S. industry,� said Patrick Di Chiro, Chairman and CEO of THUNDER FACTORY. �Our team is very excited about the opportunity to work with a great partner like Extra Space Storage, not only to improve their marketing effectiveness but, more importantly, to help them expand and grab market share. Extra Space Storage is already redefining the expectations of customers in the self storage industry, and we intend to exploit that fact as a major competitive advantage for them.�
