Pressure BioSciences, Inc. : Announces Co-Marketing/Selling and Instrument Co-Development Agreement with Digilab, Inc.

?Leading Life Sciences Tools Manufacturers for the Research Laboratory to Collaborate
on the Development, Marketing, and Sale of State-of-the-Art Sample Preparation Products

South Easton, MA, January 11, 2012 - Pressure BioSciences, Inc. (NASDAQ: PBIO) ("PBI") and Digilab, Inc. ("Digilab"), (together "the companies"), today announced that they have entered into a co-marketing/selling and research and development agreement. The companies intend to co-market and sell their respective product lines worldwide, including in industry publications, at scientific meetings, on each company's website, through common collaborator studies, at key industry trade shows, and in visits to customer sites. PBI and Digilab also intend to explore ways to co-develop new instrumentation, accessories/modules for existing instrumentation, and consumables that combine the robotics and high throughput capabilities of Digilab products with the extraction, protein digestion, and other advantages of PBI's Pressure Cycling Technology ("PCT") Platform.

One of the most significant problems in protein studies today is the proper preparation of a sample prior to its analysis. Poor sample preparation can lead to inaccurate results. Digilab and PBI believe that a combination of their respective proprietary technology platforms will provide scientists with an improved, more reproducible, integrated workflow to better address important sample preparation issues that are routinely encountered by scientists in the estimated 80,000 biological research laboratories worldwide.

Mr. Sidney Braginsky, Chairman and CEO of Digilab, said: "We believe that Digilab's suite of sample preparation, liquid handling, and identification products, coupled with PBI's unique pressure-based technology platform and PCT products, will offer the research scientist greatly enhanced sample preparation tools with a higher degree of reproducibility, versatility, throughput, and overall quality than currently available. We believe this will result in increased sales and visibility for both Digilab and PBI.

Mr. Richard T. Schumacher, President and CEO of Pressure BioSciences, said: "Digilab and PBI share the same sample preparation target market. We routinely find ourselves attending many of the same scientific meetings, advertising in many of the same media outlets, and collaborating with many of the same thought leaders in the field."

Mr. Schumacher continued: "PBI's sales and marketing activities are currently performed with four dedicated staff members and three distribution partners. These efforts will be greatly enhanced by the Digilab sales and marketing team of five staff members and their broad distribution network of over twenty distributors worldwide. Similarly, our sales and marketing team will assist Digilab in broadening the reach of their sales activities. Consequently, we believe that this alliance will greatly facilitate the introduction of our respective sample preparation product lines to research laboratories worldwide, but without the need to increase sales staff, marketing budgets, and time at scientific meetings. We believe this is a very cost-effective way to significantly increase market penetration and increase sales for both companies. We expect to begin to see these increased sales results during the first half of 2012."
