These awards comprise $2.4 million for deployment of one of OPT's PB150 PowerBuoys off the coast of Reedsport, Oregon and $2.4 million for the development of OPT's next generation 500kW PowerBuoy, the PB500. In July 2010, OPT was awarded £1.5 million (approximately $2.3 million) from the UK government's Southwest Regional Development Agency ("SWRDA") for development of the PB500.

·; Neared completion of OPT's first PB150 PowerBuoy, which is expected to be ready by the end of this month for ocean trials off the coast of Scotland.

·; OPT signed a groundbreaking agreement with 11 federal and state agencies and three non-governmental stakeholders for its utility-scale wave power project at Reedsport, Oregon.

·; Subsequent to the end of the second quarter, OPT announced the expansion of its relationship with Mitsui Engineering & Shipbuilding Co. Ltd. ("MES") with the signing of a new contract to develop OPT's PowerBuoy technology for its application in Japanese sea conditions. Under this new contract, MES and OPT will work together to develop a new mooring system for OPT's PowerBuoy, customized for wave power stations off the coast of Japan. The new system will undergo testing at MES's wave tank facilities to verify the results of extensive computer modeling.

Charles F. Dunleavy, Chief Executive Officer of OPT, said: "Building on the continued progress on our utility and autonomous PowerBuoy projects in the US and the UK, we have announced approximately $10 million of awards from customers in the US, UK and Japan since our fiscal year 2011 began in May. We are excited about the continued operation of our grid-connected buoy in Hawaii, and look forward to the completion of our first PB150 in Scotland, which we expect to be ready for ocean trials by the end of this month, and further progress with our autonomous PowerBuoy projects with the US Navy. OPT is also very pleased to build on its relationship with Mitsui Engineering and Shipbuilding, which is consistent with our global strategy to build alliances with strategic partners in key markets."

Operational Review

During the second fiscal quarter ended October 31, 2010, the Company achieved milestones in a number of ongoing projects, which include the following:

HAWAII, US -OPT completed the first grid connection of a wave energy device in the United States, at the Marine Corps Base Hawaii ("MCBH"), in conjunction with the US Navy. This connection demonstrates the ability of OPT's PowerBuoy systems to produce utility-grade, renewable energy that can be transmitted to the grid in a manner fully compliant with national and international standards. The PB40 PowerBuoy, which was deployed in December 2009, is part of OPT's ongoing program with the US Navy to develop and test the Company's wave energy technology. Key program goals include demonstrating system reliability and survivability, and the successful interconnection with the grid serving MCBH.

REEDSPORT, OREGON, US - Construction of the steel structure for the first PB150 PowerBuoy for OPT's project off the coast of Reedsport, Oregon has been completed. Fabrication of the power take-off and control system is now in process, and land testing of those systems is expected to commence in the first half of calendar year 2011. Ocean trials of the PB150 are due to commence later in calendar year 2011.

In August 2010, the Company signed an agreement with 11 federal and state agencies and three non-governmental stakeholders to support the responsible development by OPT of the next phase of the project - a 10-PowerBuoy, grid connected, wave energy station with a capacity of 1.5 MW. This agreement represents a key step towards the granting of a license by the Federal Energy Regulatory Commission ("FERC"), which would be the first such license to be issued for a commercial-scale wave power project in the US. After receipt of the FERC license and additional funding, the 10-PowerBuoy wave energy station is expected to be connected to the grid. In September 2010, OPT received a $2.4 million award from the DoE in connection with its Reedsport PB150 PowerBuoy. This is the second award to OPT by the DoE in connection with the Reedsport project following the receipt in 2008 of $2.0 million to use towards the construction of the device.

SCOTLAND, UK- Integration of the energy conversion and power take-off subassemblies with the buoy structure of OPT's first PB150 PowerBuoy is complete, and remains on track to be ready by the end of this month for in-ocean trials off the coast of Scotland. The Company is seeking additional funding for the next stage of the buoy's development after the trial phase is completed.

CORNWALL, UK- SWRDA has completed the installation of the cabling and subsea infrastructure for the Wave Hub site off the coast of Cornwall, England. In July 2010, OPT received further support from the UK government with a grant of £1.5 million (approximately $2.3 million), which was awarded by SWRDA to OPT for the development of the PB500.

US NAVY "LEAP" PROJECT - The US Navy awarded $2.75 million in additional funding to OPT for a second stage under its existing program to provide an autonomous PowerBuoy wave energy conversion system for the Navy's program for homeland protection and security. In the second stage of the program, to be performed over a one-year period, OPT will build and ocean-test a LEAP system off the coast of New Jersey. The new award follows the successful completion by OPT of the first stage of the US Navy's LEAP Program; during the first 12-month period, OPT successfully completed delivery in September 2010 of the design and testing of a new power take-off system for its autonomous PowerBuoy.

US NAVY DEEP OCEAN APPLICATION - Progress continued on OPT's ongoing project to provide autonomous PowerBuoy technology for the US Navy's Deep Water Active Detection System ("DWADS") for ocean data gathering. The building of the enhanced device is complete, and OPT successfully conducted near-shore sea trials of the system. Deep-ocean testing is expected to be conducted at a later time by the US Navy, which is anticipated to provide a ship for that test phase of the DWADS system.

PB500 PRODUCT DEVELOPMENT - During the six months ended October 31, 2010, the Company received a total of $4.7 million for the development of its PB500 PowerBuoy. The Company has set forth a strategy to fund such development primarily with external grants and other contracts, rather than use the Company's existing capital resources. When considered with the $1.5 million grant from the DoE announced in April 2010, the total of such external awards received by the Company for the development of the PB500 is $6.2 million.

Cancellation of Trading on AIM

On December 2, 2010, OPT announced 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, January 14, 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.

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 AIM Rules compliance and maintaining the quotation; and

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

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 agreed 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.

Financial Review

Second Quarter-

OPT's contract backlog at October 31, 2010 was $7.5 million, compared to $6.5 million at July 31, 2010 and $5.7 million at April 30, 2010. Reported contract backlog at October 31, 2010 does not yet include two new funding awards totaling $4.8 million from the US DoE for the deployment of one of OPT's PowerBuoys at Reedsport, Oregon and for the development of OPT's PB500, as the contracts for these two awards have not yet been received by the Company.

For the three months ended October 31, 2010, OPT reported revenues of $1.9 million, a 220 percent increase compared to revenues of $0.6 million in the three months ended October 31, 2009. The growth in revenues primarily reflects an increase in revenues from the US Navy under the LEAP program. In addition, there was an increase in revenues from OPT's PB150 PowerBuoy project in Reedsport, Oregon and revenues from OPT's PB500 development project. The growth in these projects was partially offset by a decline in revenues from OPT's PB150 PowerBuoy project in Scotland and its utility PowerBuoy project with the US Navy at the Marine Corps Base in Hawaii, which is now grid-connected.

Operating loss for the three months ended October 31, 2010 was $5.7 million compared to $5.6 million for the three months ended October 31, 2009. This change primarily reflects an increase in product development costs, principally for the PB150 system. Gross profit for the three months ended October 31, 2009 included a reduction in a provision for contract losses of approximately $300,000.

Net loss was $5.5 million for the three months ended October 31, 2010 compared to $5.2 million for the same period in the prior year. This increase in net loss was primarily due to the change in operating loss and decreases in interest income and other income.

Six Months-

For the six months ended October 31, 2010, OPT reported revenues of $3.2 million, a 71 percent increase compared to revenues of $1.9 million in the six months ended October 31, 2009. The growth in revenues primarily reflects an increase in revenues from the US Navy under the LEAP program. In addition, there was an increase in revenues from OPT's PB150 PowerBuoy project in Reedsport, Oregon and the Company's PB500 development project. The revenue increases in these projects were partially offset by declines in revenues from OPT's DWADS project with the US Navy, utility-scale project in Spain and utility PowerBuoy project with the US Navy at the Marine Corps Base in Hawaii, which is now grid-connected.

Operating loss for the six months ended October 31, 2010 was $12.0 million compared to $8.8 million for the six months ended October 31, 2009. This change primarily reflects an increase in product development costs, principally for the PB150 system, and a decrease in gross profit. Gross profit for the six months ended October 31, 2009 included a reduction in a provision for contract losses of approximately $400,000.

Net loss was $11.8 million for the six months ended October 31, 2010 compared to $7.3 million for the same period in the prior year. This increase in net loss was primarily due to the change in operating loss as noted above. In addition, other income for the six months ended October 31, 2009 included a one-time gain of $500,000 from a favorable settlement of a claim against a supplier of engineering services. For the six months ended October 31, 2010, OPT recorded a foreign exchange loss of approximately $167,000 compared to a gain of $502,000 for the six months ended October 31, 2009. This was due primarily to the change in the relative value of the US dollar compared to the British pound sterling and the Euro. Interest income was $398,000 for the six months ended October 31, 2010 compared to $533,000 for the comparable period in 2009. This decrease was due to lower interest rates and cash balances.

Cash and Investments-

On October 31, 2010, total cash, cash equivalents, restricted cash and marketable securities were $57.7 million. Net cash used in operating activities was $3.3 million and $9.4 million for the three and six months ended October 31, 2010 respectively. While OPT expects cash used in the second half of fiscal 2011 to be consistent with the first half, it expects the rate of its cash outflows to decrease in future periods, reflecting completion of significant milestones associated with the construction of its two PB150 systems for Oregon and Scotland and continued receipt of non-dilutive funding from external sources for development of the PB500.
