News Release

PENNINGTON, N.J., Dec 02, 2010 (BUSINESS WIRE) --

Ocean Power Technologies, Inc. ("OPT" or the "Company") announces that it intends to cancel the admission of its common shares (the "Shares") to trading on the AIM Market ("AIM") of the London Stock Exchange (the "Cancellation" or "de-listing"). It is anticipated that the Cancellation will become effective at 07.00 GMT on Friday, 14 January 2011.

OPT will maintain its listing on NASDAQ Global Market ("NASDAQ"), which accounts for the bulk of the trading in its shares, and is facilitating an orderly transfer of its UK-held Shares to the US stock processing system.

Reasons for the De-listing

In arriving at the decision to de-list from AIM, the Directors of OPT have taken the following matters into account:

(i) the relative inactivity, in terms of share trading volume, of the Shares on AIM compared to that on NASDAQ;

(ii) the removal of the ongoing costs associated with the Company's continuing compliance with the AIM Rules and maintaining the quotation; and

(iii) the Company's securities will continue to be traded on NASDAQ.

OPT was admitted to AIM in October 2003 and subsequently obtained a listing on NASDAQ in April 2007. Since being listed on NASDAQ, the Company's stock has experienced significantly higher liquidity in the US market compared with AIM. This is based on data provided by Yahoo Finance, NASDAQ and AIM with respect to average daily volume of Shares traded and the average number of monthly trades.

For these reasons, the Directors of OPT believe that the burden of maintaining the AIM quotation outweighs the benefits that the Company receives from its listing on AIM. The Directors unanimously agree that the de-listing will not interfere with, or inhibit, the Company's business. The Directors have therefore concluded that it is in the best interests of the Company and its shareholders to cancel its admission to AIM and maintain the listing of its securities on NASDAQ to enable all shareholders to continue to trade their Shares in the future.

Ocean Power Technologies Limited, based in Warwick, UK, remains fully committed to growing OPT's business in the United Kingdom and Europe.

Effect of the De-listing

The principal effects of the de-listing will be:

• The Shares will no longer be traded on AIM
• The Company's Depositary Interest and CREST facility will be cancelled
• The Company will no longer be required to comply with the AIM Rules or any of the corporate governance requirements for companies trading on AIM
• Nomura Code Securities will cease to be the nominated advisor and broker to the Company
• The Company will maintain its listing on NASDAQ, where its Shares will continue to be traded, and it will continue to comply with all the obligations of NASDAQ and the Securities and Exchange Commission rules in the US. All holders on the UK register on 19 January 2011 will be placed on the US register and will be issued a Direct Registration System ("DRS") advice statement by the Company's registrar and transfer agent, Computershare
• The Shares will remain freely transferable

Prior to 14 January 2011, shareholders may continue to have their Depositary Interests cancelled and have the underlying shares deposited into the US stock processing system, the Depository Trust & Clearing Corporation ("DTCC"), by contacting the UK-based Global Transaction Unit of Computershare at +44 (0)870 702 0003, ext. 1075.

Shareholders wishing to ask further questions about this process should contact Computershare at +44 (0)870 703 6162 or the Company's CFO and company secretary, Brian Posner, on +1 609 730 0400, ext. 242.
