                              AMENDED AND RESTATED
                   VOTING AND RIGHT OF FIRST REFUSAL AGREEMENT

     AMENDED AND RESTATED VOTING AND RIGHT OF FIRST REFUSAL AGREEMENT dated as
of April 18, 2005, by and among Ocean Power Technologies, Inc., a New Jersey
corporation (the "Company") (as to paragraphs 1.1, 1.7, 1.9, 2.1 and 2.2 only),
George W. Taylor ("Dr. Taylor") and Joanne Burns ("Ms. Burns").

                                   WITNESSETH:

     WHEREAS, Dr. Taylor and Ms. Burns were parties to that certain Voting and
Right of First Refusal Agreement, dated September 27, 2003 (the "Prior
Agreement"), granting Dr. Taylor certain voting and other rights with respect to
Ms. Burns' holdings of the Company's common stock, no par value per share (the
"Common Stock"); and

     WHEREAS, as of the date hereof, Ms. Burns is the record and beneficial
owner of 6,425,746 shares of the Common Stock (the "Current Shares");

     WHEREAS, pursuant to the Prior Agreement for a limited period of time, Ms.
Burns formerly desired to irrevocably constitute and appoint Dr. Taylor as her
lawful agent and proxy to vote all of the Current Shares held by Ms. Burns, as
well as any other shares resulting from a stock split, reverse stock split,
stock dividend, combination, reclassification or conversion of such shares, or
any other increase or decrease in the number of such shares effected without the
receipt of further consideration by the Company (all such shares, together with
the Current Shares, being referred to herein collectively as the "Shares");

     WHEREAS, Dr. Taylor and Ms. Burns intend to amend certain provisions of the
Prior Agreement to provide for, among other things, an extension of the term of
the agreement and to release Ms. Burns from the voting, transfer and all other
restrictions provided in the Prior Agreement relating to fifty percent (50%)
(3,212,873) of the Shares (the "Released Shares");

     NOW, THEREFORE, in consideration of the mutual covenants contained herein,
and for good and valuable consideration, the receipt and sufficiency of which is
hereby acknowledged, the parties hereto, intending to be legally bound hereby,
agree as follows:

1. Voting and Transfer Rights.

     1.1 With respect to fifty percent (50%) (3,212,873) of the Shares (the
"Proxy Shares"), Ms. Burns hereby irrevocably constitutes and appoints Dr.
Taylor as her true and lawful agent and proxy, with absolute discretion and
authority to: (a) represent, vote, give consents and in all other ways to act in
her place and stead, on any matter at any meeting of the shareholders (whether
regular, general, special or otherwise) of the Company to the same extent as Ms.
Burns could if personally present at any such meeting; and (b) express consent
or dissent to any and all corporate action in writing without a meeting on
behalf of Ms. Burns. Dr. Taylor hereby releases his existing proxy and all other
rights and restrictions granted under the Prior Agreement related to the
Released Shares. Ms. Burns, or any successor holder, shall be entitled to vote
the Released Shares on any matter duly brought before the Company's shareholders
and

<PAGE>

Ms. Burns shall be free to transfer any or all of the Released Shares at her
discretion relating to the proxy and contractual transfer restrictions. The
Company shall use commercially reasonable efforts to promptly remove the
restrictive legends (relating to the contractual voting rights and transfer
restrictions granted to Dr. Taylor) upon all certificates evidencing the
Released Shares.

     1.2 In furtherance of the foregoing, Ms. Burns hereby acknowledges that she
has executed an Irrevocable Proxy, in the form attached hereto as Exhibit A (the
"Irrevocable Proxy"), granting to Dr. Taylor an irrevocable proxy pursuant to
the provisions of Section 14A:5-19 of the New Jersey Business Corporation Act to
vote at meetings, or execute and deliver written consents or otherwise act with
respect to, all of the Proxy Shares owned by Ms. Burns as fully, to the same
extent, and with the same effect as Ms. Burns might or could do under any
applicable laws or regulations governing the rights and powers of shareholders
of a New Jersey corporation. Any prior proxy executed by Ms. Burns in favor of
Dr. Taylor or any other party is hereby terminated.

     1.3 Ms. Burns agrees that Dr. Taylor (a) may vote the Proxy Shares solely
in his own discretion and in his own best interests as if he was the sole owner
of the Proxy Shares, and (b) shall not have any fiduciary or other duty to Ms.
Burns arising solely with respect to the voting of the Proxy Shares. Except as
provided herein, Dr. Taylor shall not have any liability whatsoever to Ms. Burns
under the terms and provisions of this Agreement or the proxy delivered
simultaneously herewith by Ms. Burns.

     1.4 The irrevocable proxy provided for in this Agreement is a proxy related
to the Proxy Shares only and only of the right of a shareholder to vote for or
against, or consent or dissent from, matters submitted to a vote of
shareholders, and does not and shall not be deemed to transfer, waive or
otherwise limit any other right or powers accruing to the shareholder.

     1.5 Ms. Burns hereby acknowledges and affirms that this proxy is coupled
with an interest and is irrevocable until April 18, 2008 or sooner termination
of this Agreement, at which point, it shall automatically expire without the
need for further documentation, although Dr. Taylor agrees to promptly execute
and deliver to Ms. Burns any documentation evidencing such termination as
reasonably requested by Ms. Burns.

     1.6 Ms. Burns hereby represents and warrants that she is the legal and
beneficial owner of the Current Shares.

     1.7 The parties hereto shall do and perform or cause to be done and
performed all such further acts and things and shall execute and deliver all
such other agreements, certificates, instruments or documents as shall be
necessary or desirable in order to carry out the intent and purposes of this
Agreement including, without limitation, the execution of any such documents
required to be executed by the Company's stock transfer agent.

     1.8 THIS AMENDED AND RESTATED VOTING AND RIGHT OF FIRST REFUSAL AGREEMENT
AND THE ATTACHED PROXY SHALL REMAIN IN FULL FORCE AND EFFECT AND BE ENFORCEABLE
AGAINST ANY PERMITTED DONEE, TRANSFEREE OR ASSIGNEE OF THE SHARES IN ACCORDANCE
WITH THEIR TERMS AS TO THE PROXY SHARES UNTIL APRIL 18, 2008.


                                       -2-

     1.9 Upon execution of this Agreement, the Company shall be required to
imprint or otherwise place, on certificates representing the Proxy Shares the
following legend (the "Legend"):

     "THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A IRREVOCABLE
     PROXY AND THE TERMS AND CONDITIONS OF AN AMENDED AND RESTATED VOTING AND
     RIGHT OF FIRST REFUSAL AGREEMENT (THE "VOTING AGREEMENT') WHICH PLACES
     CERTAIN RESTRICTIONS ON THE VOTING OF THE SHARES REPRESENTED HEREBY. ANY
     PERSON ACCEPTING ANY INTEREST IN SUCH SHARES SHALL BE DEEMED TO AGREE TO
     AND SHALL BECOME BOUND BY ALL THE PROVISIONS OF SUCH PROXY AND VOTING
     AGREEMENT. A COPY OF SUCH VOTING AGREEMENT WILL BE FURNISHED TO THE RECORD
     HOLDER OF THIS CERTIFICATE WITHOUT CHARGE UPON WRITTEN REQUEST TO THE
     COMPANY AT ITS PRINCIPAL PLACE OF BUSINESS."

The Company agrees that, while Ms. Burns is bound by the terms of this
Agreement, it will not remove, and will not permit to be removed, the Legend
from any certificate representing Ms. Burns' Proxy Shares and will place or
cause to be placed the Legend on any new certificate issued to represent the
Proxy Shares theretofore represented by a certificate carrying the Legend. Once
Ms. Burns is no longer bound by this Agreement, the Company shall reasonably
promptly remove the restrictive legend relating to the contractual restrictions
set forth herein from Ms. Burns' certificate(s) representing the Proxy Shares.
The Company will reasonably promptly remove the existing legend relating to the
contractual restrictions from the Released Shares.

2. Restrictions on Transfer.

     2.1 Any sale, transfer or other disposition, whether voluntarily or by
operation of law ("Transfer") of any of the Proxy Shares by Ms. Burns, other
than according to the terms of this Agreement, shall be void and transfer no
right, title, or interest in or to any of such Proxy Shares to the purported
transferee.

     2.2 An original copy of this Agreement, duly executed by each of the
parties hereto, shall be delivered to the Secretary of the Company and
maintained at the principal executive office of the Company and made available
for inspection by any person requesting it.

3. Offer of Sale: Notice of Proposed Sale. If Ms. Burns desires to Transfer any
of her Proxy Shares, or any interest in such Proxy Shares, Ms. Burns shall first
deliver written notice of her desire to do so (the "Notice") to Dr. Taylor and
the Company, in the manner prescribed in Section 7.4 of this Agreement. The
Notice must specify: (a) the name and address of the party to which Ms. Burns
proposes to sell or otherwise dispose of the Proxy Shares or an interest in the
Proxy Shares (the "Offeror"), (b) the number of Proxy Shares Ms. Burns proposes
to sell, transfer or otherwise dispose of (the "Offered Shares"), (c) the
consideration per Share to be delivered to Ms. Burns for the proposed sale,
transfer or disposition, and (d) all other material terms and conditions of the
proposed transaction. For purposes of clarity, Ms. Burns shall be entitled to
transfer the Released Shares free of restriction by this Agreement or any
predecessor agreement between the parties, subject to applicable securities and
other laws.

4. Dr. Taylor's Option to Purchase.

     4.1 Dr. Taylor shall have the first option to purchase all or any part of
the Offered Shares for the consideration per share and on the terms and
conditions specified in the Notice. Dr. Taylor must exercise such option, no
later than 30 days (the "Option Period") after such Notice is deemed under
Section 7.4 hereof to have been delivered to it, by written notice to Ms. Burns.

     4.2 In the event Dr. Taylor duly exercises his option to purchase all or
part of the Offered Shares, the closing of such purchase shall take place at the
offices of the Company on the date five days after the expiration of the Option
Period.

     4.3 To the extent that the consideration proposed to be paid by the Offeror
for the Offered Shares consists of property other than cash or a promissory
note, the consideration required to be paid by Dr. Taylor under Sections 3 and 4
hereof may consist of cash equal to the value of such property, as determined in
good faith by agreement of Ms. Burns and Dr. Taylor acquiring such Offered
Shares.

5. Failure to Fully Exercise Option. If Dr. Taylor does not elect to purchase
the full number of Offered Shares, Ms. Burns shall be entitled to sell to the
Offeror, according to the terms set forth in the Notice, that number of her own
Shares which equals the difference between the number of Shares desired to be
purchased by the Offeror and the number of Shares Dr. Taylor purchases pursuant
to Section 4. If Ms. Burns wishes to Transfer any such Shares at a price per
Share which differs from that set forth in the Notice, upon terms different from
those previously offered to Dr. Taylor, or more than 60 days after the
expiration of the Option Period, then, as a condition precedent to such
transaction, such Shares must first be offered to Dr. Taylor on the same terms
and conditions as given the Offeror, and in accordance with the procedures and
time periods set forth above.

6. Termination and Exceptions.

     6.1 This Agreement and all rights of Dr. Taylor and restrictions upon Ms.
Burns hereunder and the Proxy Shares shall terminate on the earlier of the
following: (a) April 18, 2008; (b) the termination thereof by the written
consent of Ms. Burns and Dr. Taylor; (c) the death of Dr. Taylor; (d) the
permanent mental incapacity of Dr. Taylor (determined by the consensus of three
qualified physicians, one of whom shall be selected by Dr. Taylor's family, one
of whom shall be selected by Ms. Burns and the third physician shall be selected
by the other two physicians); (e) the consummation of an initial public offering
by the Company of its Common Stock pursuant to an effective Registration
Statement filed with the U.S. Securities and Exchange Commission with gross
proceeds to the Company of at least $25 million; (f) the consummation of the
sale of all, or substantially all, of the assets or stock of the Company; and
(g) the sale by Dr. Taylor to an unaffiliated third party of more than 3,212,873
shares of the Company's Common Stock, adjusted for stock splits and similar
events.

     6.2 Transfer Restriction Exception. Notwithstanding Section 3 hereof,
during the term of this Agreement, in the event Dr. Taylor sells more than
2,000,000 shares (as adjusted for stock splits and similar events) of his
current holdings (the "Threshold Amount"), Ms. Burns


                                       -4-

<PAGE>

shall be entitled to sell one share for each share sold by Dr. Taylor in excess
of the Threshold Amount free of the transfer restrictions set forth herein. Dr.
Taylor shall provide Ms. Burns with reasonably prompt notice of each sale he
makes.
