LAVAL, Quebec, July 12, 2013 (GLOBE NEWSWIRE) -- Neptune Technologies & Bioressources Inc. (" Neptune") (Nasdaq:NEPT) (TSX:NTB) announces today it has acquired, through the exercise of a previously issued warrant (the " Warrant"), 6,750,000 Class A common shares (the " Shares") in the capital of Acasti Pharma Inc. (" Acasti"), a majority-owned subsidiary of Neptune. The Shares were acquired at a price of CDN$2.30 per Share upon the exercise of the Warrant. This reflects a total exercise price of approximately CDN$15.5 million. The Warrant was delivered to Neptune pursuant to a royalty prepayment agreement, dated December 4, 2012, entered into between Neptune and Acasti (the " Prepayment Agreement"), under which Acasti has exercised the option embedded in its exclusive technology license agreement dated August 7, 2008 entered into between Acasti and Neptune (the " License Agreement") to pay in advance all of the future royalties payable under the License Agreement. As a result of the royalty prepayment transaction, Acasti is no longer required to pay any royalties to Neptune under the License Agreement during its term for the use of the intellectual property under license. The exercise of the Warrant has increased Neptune's equity participation in Acasti from approximately 57% to approximately 60% as at July 12, 2013. The Prepayment Agreement and the issuance of the Shares to Neptune have been approved by the TSX Venture Exchange and the disinterested shareholders of Acasti (excluding Neptune and non-arm's length parties to Neptune) at the annual meeting of shareholders of Acasti held on June 27, 2013.
