Diversinet Appoints Bret Jorgensen as Chairman of the Board

Seasoned Healthcare Entrepreneur Brings Strong Track Record in Building Highly Successful Companies

TORONTO, July 5, 2012 /PRNewswire/ - Diversinet Corp. (TSX Venture: DIV, OTCBB: DVNTF), a leader in secure mobile health, has appointed Bret W. Jorgensen as chairman of the board succeeding Albert Wahbe, who has retired as chairman but remains a member of the board.

Jorgensen brings over 20 years of experience as a healthcare entrepreneur and corporate transformation executive to Diversinet. He has deep leadership experience in rapid-growth, technology-enabled health services organizations and a proven record in corporate fundraising, strategy execution and value creation. Jorgensen was most recently the CEO of MDVIP, a personalized healthcare company that offers primary and preventive care services in 40 states. He left the company in early 2010 after a successful sale to Procter & Gamble. He currently serves as director of MDVIP.

Previously, as CEO, he restructured InSight Health, a diagnostic-imaging business with more than 200 service sites. Earlier in his career, Jorgensen was co-founder and president of TheraTx Health Services, a large, fast-growing healthcare services company with 240 sites, 5,000 employees and an innovative point-of-care HCIT solution, TheraSys. TheraTx was recognized as the 2^nd fastest growing public company by Inc. magazine and Jorgensen received the "Entrepreneur of the Year" Award in Healthcare for this effort. He left the company after a successful sale to Kindred.

Jorgensen also currently serves as chairman of Crossover Health, an innovative worksite health provider, and a board member of the Kravis Leadership Institute. He is a strategic advisor to Qualcomm Life, which offers the 2net platform for mobile health, and Hello Health, which provides an unique patient engagement platform, and has served as a director of several other public and private healthcare companies.

The appointment of Jorgensen follows Diversinet's recent appointment of Dr. Hon Pak as the company's CEO. While Jorgensen brings to Diversinet a career-long record of accomplishment in founding and growing technology enabled healthcare services companies, Pak is contributing strong hands-on experience as a clinician and healthcare IT executive. Given their long service at the forefront of improving the U.S. healthcare delivery, they will work together to lead Diversinet as it focuses on patient engagement and care coordination with its innovative applications of secure mobile technology.

"We are very fortunate to have attracted two deeply experienced and forward-thinking healthcare professionals," noted Wahbe. "The healthcare environment is evolving rapidly, with an emphasis on patient-centered mobile technology, and Bret and Hon bring the right mix of experiences to drive Diversinet's success."

"This is an exciting time to join Diversinet," Jorgensen said. "It is clear there is a growing demand for mobile-enabled patient engagement and care coordination tools and the company's MobiSecure^® technology is well positioned to succeed in this emerging market. I look forward to working closely and actively with Dr. Pak and the Board to lead Diversinet."

Mr. Jorgensen has been issued stock options to purchase up to 863,562 common shares of Diversinet Corp. exercisable at U.S.$0.09 per common share for a five-year term.
