Matthew B. Potter Joins Pressure BioSciences, Inc. as Vice President of Sales

SOUTH EASTON, Mass., March 11 /PRNewswire-FirstCall/ -- Pressure BioSciences, Inc. (Nasdaq: PBIO) ("PBI") today announced that Matthew B. Potter has joined PBI's senior executive management team as Vice President of Sales. Mr. Potter brings with him nearly twenty years of experience in sales and sales management at a number of leading life sciences companies. Mr. Potter will oversee PBI's seven US-based, regional sales directors and will be responsible for driving the Company's commercialization of its novel and patented pressure cycling technology (PCT) product line.

Mr. Richard T. Schumacher, PBI's Founder, President, and CEO stated: "This is an important and exciting time for our Company, as our efforts in 2008 are clearly focused on both the development of market awareness for PCT and on the expansion of our small but growing customer base. To this end, we believe that Matt's background and management style is a not only a great fit with our team, but should also help to accelerate our PCT commercialization plan. We consider ourselves very fortunate to have someone of Matt's caliber join our management team."

Mr. Schumacher continued: "In addition to bringing significant sales and sales leadership experience to PBI, the hiring of Matt allows Dr. Nathan Lawrence, who previously led both sales and marketing, to focus all of his efforts on marketing, collaboration support, distribution outside of the United States, and liaison activities between collaborators and our scientific and engineering teams. This new focus for Dr. Lawrence will allow us to align our sales and marketing efforts in a manner that supports our Company's transition to a fully commercial operation in 2008."

About Matthew B. Potter

Over his career, Mr. Potter has been a Sales Manager at Pharmacia Biotech; National Sales Director at Visible Genetics; Director, Sales and Marketing at MicroCal, LLC; National Sales Manager, Key Accounts -- Pharma at Qiagen, Inc; and Vice President of Sales and Marketing at Abcam, Inc. Before his transition into sales, Mr. Potter was a researcher at the Worcester Foundation for Experimental Biology. Mr. Potter holds a BA in Biology from Clark University and an MBA from Assumption College, both located in Worcester, MA.

Mr. Potter commented: "In over 19 years of selling products into the research marketplace for the analysis of nucleic acids, proteins, and small molecules, one issue -- how to achieve high quality extraction of bio- molecules prior to analysis -- nearly always rose to the top. This was always a key issue, and to that end, I believe strongly that the PCT Sample Preparation System answers many of the sample preparation problems that researchers encounter, and offers unique advantages to customers looking to extract DNA, RNA, proteins, and small molecules from a wide variety of biological samples. PBI has a dedicated and talented group of people throughout the organization, and I look forward to working with them -- and in particular our newly hired field sales organization -- to drive this technology into the marketplace."
