                                 PROMISSORY NOTE

$400,000                                                      Date:  May 3, 2007

         FOR VALUE RECEIVED, the undersigned, SEAENA, INC., a Nevada corporation
("MAKER"),  promises to pay to U.C.  LASER LTD., a company  organized  under the
laws of the State of Israel ("HOLDER"), at such place or places as may from time
to time be  designated by Holder,  the  principal  sum of Four Hundred  Thousand
Dollars  ($400,000).  This Note  evidences  a loan (the  "LOAN")  from Holder to
Maker. This Loan will bear no interest.

         The outstanding principal balance of this Note shall be due and payable
in full on November 3, 2007 or earlier  upon sale by Maker of the Seaena Class B
Stock (as defined in the Agreement and Mutual Release of even date herewith), or
any other equity  interest in Maker exceeding  twenty-five  percent (25%) of the
voting  rights of equity  holders in Maker,  in one  transaction  or a series of
transactions.

         All payments hereunder shall be made in immediately  available funds in
lawful money of the United  States which shall be legal tender in payment of all
debts at the time of payment.

         This  Note is  governed  by the laws of the  State of  Nevada,  without
regard to the choice of law rules of that State.

         If Holder  delays in  exercising or fails to exercise any of its rights
under this Note,  that delay or failure shall not  constitute a waiver of any of
Holder's rights,  or of any breach,  default or failure of condition of or under
this  Note.  No waiver by Holder of any of its  rights,  or of any such  breach,
default  or  failure  of  conditions  shall be  effective,  unless the waiver is
expressly  stated in a writing  signed by Holder.  All of  Holder's  remedies in
connection  with this Note or under  applicable  law  shall be  cumulative,  and
Holder's  exercise of any one or more of those  remedies shall not constitute an
election of remedies.

         This  Note  inures  to and  binds  the  heirs,  legal  representatives,
successors and assigns of Holder and Maker;  PROVIDED,  HOWEVER,  that Maker may
not assign this Note or assign or delegate any of its rights or obligations.

         If any  action  is taken by  Holder  (whether  by Court  proceeding  or
otherwise) to enforce payment of this Note, the  undersigned  promises to pay to
Holder any and all costs of such action,  including  all  reasonable  attorneys'
fees and costs incurred therein.
