Item 1.01
Entry into a Material Definitive Agreement.
On or about September 30, 2011, 46 of the 47 holders of both the outstanding Series A Convertible Preferred Stock, par value $0.01 per share (the "
Series A Preferred Stock
") and Series A 30-Month Common Stock Purchase Warrants, issued in the Series A Convertible Preferred Stock financing completed by Pressure BioSciences, Inc. (the "
Company")
in February 2009 (the "
Series A Warrants
"), voluntarily converted an aggregate of 247,187 shares of Series A Preferred Stock into 2,471,870 shares of the Company's Common Stock, $0.01 par value per share (the "
Common Stock
").  In connection with this conversion into Common Stock, the Company entered into Amendment No. 2 to the Series A Warrants (the "
Series A Warrant Amendment
") with the 46 holders under which the Series A Warrants were amended to reduce the exercise price from $1.74 to $0.90 and to extend the term of the Series A Warrants until August 12, 2016 and, with respect to affiliates, August 12, 2015.  Following the conversion of the Series A Preferred Stock by such holders, there remain 13,948 shares of Series A Preferred Stock outstanding.
Also on or about September 30, 2011, all 34 of the holders of the outstanding Series B Convertible Preferred Stock, par value $0.01 per share (the "
Series B Preferred Stock
") and the Series B Stock Purchase Warrants (the "
Series B Warrants
"), issued in the Series B Convertible Preferred Stock financing completed by the Company in November 2009 and March 2010, voluntarily converted an aggregate of 82,831 shares of Series B Preferred Stock into 828,310 shares of the Company's Common Stock.  In connection with this conversion into Common Stock, the Company entered into Amendment No. 2 to the Series B Warrants (the "
Series B Warrant Amendment
") with each of the holders, under which the Series B Warrants were amended to reduce the exercise price from $2.38 to $1.43, for Series B Warrants issued in November 2009, and from $2.88 to $1.75, for Series B Warrants issued in March 2010 and to extend the term of the Series B Warrants until August 12, 2016 and, with respect to affiliates, August 12, 2015.  Following the conversion of the Series B Preferred Stock by such holders, there are no longer any shares of the Series B Preferred Stock outstanding.
As previously disclosed in the Current Report on Form 8-K filed by the Company with the Securities and Exchange Commission on August 11, 2011, all outstanding Series B Warrants were amended at that time to provide that they were exercisable for that number of shares of Common Stock of the Company into which the shares of Series B Preferred Stock subject to the Series B Warrant were previously convertible, with a per share exercise price equal to one-tenth of the original exercise price.
In connection with the Series A Warrant Amendment and the Series B Warrant Amendment, the holders of the Series A Warrants and Series B Warrants also waived all registration rights they may have with respect to the Company's Common Stock through September 30, 2012.
The Series A Warrant Amendment and the Series B Warrant Amendment are filed as Exhibit 4.1 and Exhibit 4.2, respectively,  to this Current Report on Form 8-K and are incorporated herein by reference.
