                        UNSECURED DEMAND PROMISSORY NOTE

         THIS  INSTRUMENT IS SUBJECT TO THE TERMS OF A  SUBORDINATION  AGREEMENT
MADE BY KEVIN T. RYAN IN FAVOR OF NORTH FORK BANK DATED JUNE 2, 2006.

$882,500                                                      Date: May 31, 2006

         FOR VALUE RECEIVED, the undersigned, SEAENA, INC., a Nevada corporation
("MAKER"),  promises to pay to KEVIN T. RYAN ("HOLDER"), at such place or places
as may from time to time be  designated  by Holder,  the  principal sum of Eight
Hundred Eighty-Two Thousand Five Hundred Dollars ($882,500). This Note evidences
a loan (the  "LOAN") from Holder to Maker.  This Loan will bear  interest as set
forth below.

         The  outstanding  principal  balance of this Note and all  accrued  and
unpaid interest  thereon shall be due and payable in full upon demand of Holder.
Interest at the rate of ten percent (10%) per annum will be due and payable upon
any payment of principal of this Note.

         All payments hereunder shall be made in immediately available funds and
be credited  first to accrued  interest  and next to reducing the balance of the
principal.  Any and all payments  hereunder  shall be payable 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 contitute 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.

                                   "MAKER"
