In a separate announcement, Cipher has acquired preferred shares of IMAGIN Diagnostics Centres, Inc. (IMAGIN), a Canadian company. IMAGIN shares will be convertible into 33.3 % of IMAGIN's equity or, at Cipher's option, into the total convertible debt position held by IMAGIN in Positron Corporation, a Houston-based company that trades under the symbol POSC (OTCBB:POSC). Upon IMAGIN's completion of funding the convertible debt position of Positron, IMAGIN Molecular will hold securities convertible into 64 million shares of Positron that represents 53% of the current state equity capitalization and currently is equivalent of US$7.0 million in market value.

IMAGIN will continue to hold significant equity positions in Canada's only two independent, non-public hospital-controlled PET Centres located in Vancouver and the Toronto suburb of Mississauga, Ontario.

Patrick G. Rooney, Chairman of Cipher Holding, Inc. (OTCBB:CIHR) as well as Chairman of Positron Corporation (OTCBB:POSC) stated, "We believe that PET technology will continue to make giant strides in the diagnosis and management of cancer, heart disease, and Alzheimer's patients in the future. Our first interest is the investment position in Positron Corporation. Positron was a pioneer in the PET industry since 1983. Medicare reimbursement did not come to PET procedures in the USA until 1998, while in Canada PET procedures are not yet approved for reimbursement today. IMAGIN is the leading PET scan Company in Canada. Currently in Canada, PET procedures are performed under clinical trials using radiopharmaceuticals imported from American border cities. The PET industry is at an early stage of making a huge impact globally. Under its new banner, Imagin Molecular Corporation, Cipher Holding Corp. has a plan to capture a significant strategic foothold in PET markets worldwide."
