Calypte Only Company with Full Menu of Tests.

Prior to his involvement with WAPMERR, in 2003 Mr. Karas co-founded and served as Managing Director of Strategic Energy Investment Group in Dubai. He started this group following his retirement from Petroleum Geo-Services (PGS) in Houston, Texas where he served as Senior Vice President of Business Development for two years before moving to Dubai where he set up and, for the next eight years, served as President of PGS for the Middle East Region. Mr. Karas served, as well, as the executive vice president for Grant Tensor Geophysical in Houston-Texas and as the president of Tensor Geophysical in Egypt. Mr. Karas attended AinShams University, University of Texas and University of Houston. He holds degrees in Geophysics and Operations Research as well as a Masters Degree in electrical engineering and an MBA.

Roger I. Gale, President and CEO of Calypte stated, "We are pleased to welcome Mr. Karas to our Board and look forward to his knowledge and guidance as we expand, with his help, into regions where our non-invasive HIV/AIDS rapid test is much needed, including the Middle East and Asia. Further, we expect his knowledge of and contacts in Thailand, where we have outsourced manufacturing, and Switzerland, where many key humanitarian agencies are headquartered, will help us facilitate our business opportunities as well. As Calypte focuses on the emerging HIV epidemic countries, I expect that Mr. Karas will play a vital role in Calypte's growth in those areas of the world. We intend to use his strong technical training - he is, quite simply, a quick study - and his many years of varied international experience, including establishing cross border entities and mergers and acquisitions. He has strong relationships with key business and governmental leaders in this area as well."

Mr. Karas commented, "I am honored to be a part of Calypte at this critical juncture - the start of its "journey" to quote management. I expect to be effective in assisting the Company from my own base of operations in Dubai. I consider Calypte a lean, point of care diagnostic testing company, today focused on HIV, but with the capability to do much more. My experience supports the Company's newly articulated strategy - that physical presence is essential; being on the ground regionally to aggressively get close to the customer and understand the uniqueness of the many regions in which Calypte operates."

"I personally took a company that was headquartered in Houston to Dubai, set up a regional center and then used the in-country advantage to capture a 50% market share. I believe Calypte's simple, accurate, non-invasive products will be well received in this part of the world. I have personally accompanied management and visited key business contacts in UAE and have seen for myself the strong interest Calypte's products generate," Mr. Karas continued.

"While multiple outcomes are possible, our objective for beginning the FDA regulatory process is to ultimately receive approval for manufacturing and distribution of an over-the-counter ("OTC") oral fluid HIV diagnostic test in the U.S.", Mr. Gale concluded.

Calypte plans to occupy its new facility in September 2007.

About U.S. HIV/Aids:

The U.S. is the largest market for HIV diagnostic tests in the world, with 2005 revenues for screening tests estimated at $165 million. An FDA advisory panel has recently announced its support for having an OTC test available in the U.S. In September 2006, the CDC updated its HIV testing guidelines, specifically recognizing the benefits of rapid tests in timely communicating HIV status to patients. The CDC's revised recommendations include routine HIV testing for patients in all health-care settings after the patient is notified that testing will be performed unless the patient declines (opt-out screening); at least annual testing for persons at high risk for HIV infections; and routine opt-out screening for all pregnant women.

Mr. Gale continued, "This DCAI approval is a significant milestone in the advancement of our business; a very exciting time for all of us at the Company. Once our non-invasive HIV diagnostic tests gain market acceptance, we anticipate significant growth in market share of such tests. In addition to creating a distribution network, we expect to establish both research and manufacturing operations in India. While we will initially enter the Indian market with our HIV-1/2 oral fluid rapid test, we are also considering introducing our Aware(TM) HIV-1/2 rapid tests using both blood and urine samples to complement the current oral fluid test. India is also a logical center for development of Calypte's new products."

About India:

India has a population of over 1.1 billion, second only to China. According to recently published 2006 estimates by the National AIDS Control Organization or NACO, supported by both UNAIDS and WHO, India has an estimated 2.5 million HIV infections, ranking third behind South Africa and Nigeria for the highest number of HIV/AIDS infected people. Mr. Naresh Dayal, Secretary Health and Chair of the National AIDS Control Board said, " ... we cannot be complacent. The steady and slow spread of the HIV infection is a worrying factor."

The announcement of these new HIV estimates coincides with the launch of a 5-year, $2.8 billion AIDS campaign by the Government of India to prevent the spread of the virus among the country's large under-25 population. Calypte believes that a simple and cost effective non-invasive rapid test is an ideal solution to safely and quickly identify HIV/AIDS patients for treatment and care in large-scale programs such at this.
