SOUTH EASTON, Mass., Dec. 15, 2015 /PRNewswire/ -- Pressure BioSciences, Inc. (OTCQB: PBIO) ("PBI" and the "Company"), a leader in the development and sale of broadly enabling, pressure cycling technology ("PCT")-based sample preparation solutions to the worldwide life sciences industry, today announced it has eliminated 100% of the Company's variable rate (floorless) convertible debt following the receipt of $730,000 in gross proceeds from the fourth closing of its $5 million Private Placement (the "Offering").  This closing increased the total amount raised in the Offering to $4,755,000.  One or more additional closings are expected in the near future.

Pursuant to the Subscription Agreement, the Company will issue to the investors, senior secured convertible debentures with a fixed conversion price of $0.28 per restricted common share, and common stock purchase warrants exercisable into a total of 1,303,571 shares of restricted common stock at an exercise price of $0.40 per share. The Company is under no obligation to file a registration statement to register the shares underlying the Debentures and Warrants. The Company netted $657,000 in cash from the fourth closing after taking into account fees related to the Offering.

Mr. Richard T. Schumacher, President and CEO of PBI, commented: "With the funds raised to date, we have successfully completed the number one goal of the Offering: the elimination of 100% of the Company's variable rate (floorless) convertible debt.  Since the initial close of the Offering in July 2015, we have paid off approximately $2.7 million of variable rate loans.  Although we have never allowed any of this debt to convert under the terms of the loans, I am certain it is very comforting to all stakeholders in PBI to know that all of these loans are now completely paid off."

Mr. Schumacher continued: "Funds received in the Offering have also been used for important and timely operating activities.  Specifically, we have begun to expand our marketing and sales areas while concomitantly increasing our manufacturing and other operating capabilities."

This press release is not an offer to sell or a solicitation of offers to participate in the Offering. The units, including the shares underlying the Debentures and Warrants, have not been registered under the Securities Act and may not be sold in the United States absent registration under the Securities Act or an applicable exemption from registration.

For more information on the Offering, please see the Form 8-K filed by the Company on July 28, 2015.
