Solana MedSpas, the nation's foremost developer and syndicator of medical spas, has signed a Letter of Intent with LifeStem, Inc., a CalbaTech, Inc. subsidiary, to offer their unique Stem Cell MicroBank Service through the Solana MedSpa network. The announcement was made by Solana MedSpas
CEO and co-founder John Buckingham. CalbaTech is a publicly traded emerging life sciences company concentrating on providing products and platforms to the research market for biotech and pharmaceutical companies and to academic institutions.

'Solana MedSpas will be first medspa network to harvest adult stem cells,' Buckingham states, noting that plans are to test the service in up to six medspa locations. 'As the medspa industry leader, part of our overall strategy is to continually evaluate new technologies and services that will exclusively deliver leading edge products and services to our medspa client / owners.

Adding LifeStem's Stem Cell MicroBank Service to our locations not only positions Solana MedSpas as completely unique vis-a-vis the competition, but it represents the next logical step with regard to our vision and mission. As Solana MedSpas orchestrates the marriage of healthcare product innovation with our ever expanding medspa distribution channel, high tech life science and healthcare companies of all types are seeking us out because of
the opportunities for distributing their products and services,' Buckingham says. Solana MedSpas has opened medspas throughout the United States and plans
to have 70 in operation by the end of 2006.

LifeStem president Dan Fulkerson adds, 'Our model for collecting and storing adult stem cells through our Stem Cell MicroBank Service is a perfect fit with the medspa market. The demographic that we're targeting is almost
identical to the Solana MedSpas client base and by joining forces, we will have access to the nation's largest distribution channel into the rapidly
growing medspa market. We envision our relationship with Solana MedSpas generating substantial results for both companies.'
