    FOR
      VALUE RECEIVED,
      Travel
      Hunt Holdings, Inc., a Delaware corporation (the “Maker”), unconditionally
      promises to pay to the order of Fountainhead Capital Management Limited, having
      an address at 1
      Portman
      House, Hue Street St. Helier, Jersey, Channel Islands JE4 5RP (the
      “Payee”), the principal sum of Five Hundred Sixty One Thousand Dollars
      ($561,000), at
      a
      simple interest rate of two and one-half percent
      (2.5%) per
      annum
      computed on the basis of a 360 day year. The
      Maker
      further agrees to pay all costs of collection, including reasonable attorneys’
fees, incurred by the Payee or by any other holder of this Promissory Note
      (this
“Note”) in any action to collect this Note, whether or not suit is
      brought.

    

    Principal
      and accrued interest shall be payable on September 30, 2008 (“Maturity”), except
      that this
      Note
      shall accelerate upon
      the
Maker’s
      consummation of a private placement transaction (the “Financing”) in which it
      sells or issues shares of its common stock in a manner that is exempt from
      the
      registration requirements of the Securities Act of 1933, as amended, where
      the
      gross proceeds to the Maker of such Financing are at least $1,000,000 and in
      such event (an “Acceleration Event”) the principal and accrued interest shall be
      payable upon the consummation of such Financing.
      The
      proceeds of the Financing shall not be used for any purpose until the Maker
      pays
      all amounts due under this Note from such proceeds. The Maker shall have the
      right at any time to prepay, in whole, but not in part, the principal and
      accrued interest without penalty or notice to the Payee.
      If, but
      only if, the principal and accrued interest on this Note is not paid in full
      at
      Maturity or upon an Acceleration Event, or an Event of Default, then this Note
      shall become convertible into a number of shares of the Common Stock of the
      Maker that is equal to twelve and 75/100 percent (12.75%) of the outstanding
      Common Stock of the Maker on a fully-diluted, post-issuance basis (the
“Conversion Shares”). In order to convert this Note into Conversion Shares, the
      Payee must demand conversion in writing within the ninety (90) day period
      following Maturity, an Acceleration Event, or an Event of Default. The
      Conversion Option shall only be exercisable in the event that this Note is
      not
      paid in full on or prior to Maturity, an Acceleration Event or an Event of
      Default. Notwithstanding the foregoing, if, at the time that this Note becomes
      convertible, there is insufficient authorized shares of the Maker’s Common Stock
      available for issuance to the Payee upon conversion hereof, then the Maker
      shall
      be obligated to use its best efforts to promptly amend its certificate of
      incorporation to authorize additional shares of its Common Stock such that
      all
      of the Conversion Shares may be issued upon conversion of this Note and, if
      this
      Note becomes convertible at a time when there is insufficient authorized Common
      Stock, then the Maker shall not be permitted to convert this Note until there
      is
      sufficient authorized Common Stock of Maker and the ninety (90) day period
      referred to above shall be tolled until such time as there is sufficient
      authorized Common Stock of Maker. The Company shall use its best efforts to
      increase its authorized capital stock as soon as practicable, but in any even
      within ninety (90) days, so that there will be sufficient authorized shares
      of
      capital stock to permit the conversion of this Note.

    

    The
      amounts due hereunder are payable without deduction or offset in lawful money
      of
      the United States of America in immediately available funds to the Payee at
      its
      address as set forth above, or at such other place as the Payee shall from
      time
      to time designate. 

    

    It
      shall
      be an event of default (“Event of Default”), and the then unpaid portion of this
      Note shall become immediately due and payable, at the election of Payee, upon
      the occurrence of any of the following events:

     

    (a) any
      failure on the part of the Maker to make any payment hereunder when due, whether
      by the occurrence of an Acceleration Event or otherwise;

    

    (b) The
      Maker
      shall commence (or take any action for the purpose of commencing) any proceeding
      under any bankruptcy, reorganization, arrangement, readjustment of debt,
      moratorium or similar law or statute; or

    

    (c) a
      proceeding shall be commenced against the Maker under any bankruptcy,
      reorganization, arrangement, readjustment of debt, moratorium or similar law
      or
      statute and relief is ordered against the Maker, or the proceeding is
      controverted but is not dismissed within sixty (60) days after the commencement
      thereof.

     

    No
      failure on the part of the Payee or any other holder of this Note to exercise
      and no delay in exercising any right, remedy or power hereunder or under any
      other document or agreement executed in connection herewith shall operate as
      a
      waiver thereof, nor shall any single or partial exercise by the Payee or any
      other holder of this Note of any right, remedy or power hereunder preclude
      any
      other or future exercise of any other right, remedy or power.

    
      
         

      

      
         

        
          

        

      

      
         

      

    

     

    This
      Note
      shall be binding upon the Maker and the Maker’s successors and
      assigns.

    

    This
      Note
      shall be governed by and construed in accordance with the laws of the State
      of
      New York, excluding the conflicts of laws principles thereof.

    

    In
      the
      event that any one or more of the provisions of this Note shall for any reason
      be held to be invalid, illegal or unenforceable, in whole or in part, or in
      any
      respect, or in the event that any one or more of the provisions of this Note
      shall operate, or would prospectively operate, to invalidate this Note, then,
      and in any such event, such provision or provisions only shall be deemed null
      and void and of no force or effect and shall not affect any other provision
      of
      this Note, and the remaining provisions of this Note shall remain operative
      and
      in full force and effect, shall be valid, legal and enforceable, and shall
      in no
      way be affected, prejudiced or disturbed thereby.

    

    All
      agreements between the Maker and the Payee are hereby expressly limited so
      that
      in no event whatsoever, whether by reason of deferment in accordance with this
      Note or under any agreement or by virtue of the Maturity of the Note or the
      occurrence of an Acceleration Event, or otherwise, shall the amount paid or
      agreed to be paid to the Payee hereunder or to compensate Payee for damages
      to
      be suffered by reason of a late payment hereof, exceed the maximum permissible
      under applicable law. If enforcement of any provision hereof at the time
      performance of such provision shall be due, shall exceed the limit of validity
      prescribed by law, the relevant obligations to be fulfilled shall be deemed
      reduced to the limit of such validity. This provision shall never be superseded
      or waived and shall control every other provision of all agreements between
      the
      Maker and the Payee. 

    

    Subject
      to the applicable cure periods contained herein, time is of the essence of
      this
      Note. 

    

    EXCEPT
      AS
      OTHERWISE SPECIFICALLY PROVIDED HEREIN, THE MAKER, AND ALL OTHERS THAT MAY
      BECOME LIABLE FOR ALL OR ANY PART OF THE OBLIGATIONS EVIDENCED BY THIS NOTE,
      HEREBY WAIVES PRESENTMENT, DEMAND, NOTICE OF NONPAYMENT, PROTEST AND ALL OTHER
      DEMANDS AND NOTICES IN CONNECTION WITH THE DELIVERY, ACCEPTANCE, PERFORMANCE
      OR
      ENFORCEMENT OF THIS NOTE, AND DOES HEREBY CONSENT TO ANY NUMBER OF RENEWALS
      OR
      EXTENSIONS OF THE TIME OF PAYMENT HEREOF AND AGREE THAT ANY SUCH RENEWALS OR
      EXTENSIONS MAY BE MADE WITHOUT NOTICE TO ANY SUCH PERSONS AND WITHOUT AFFECTING
      THEIR LIABILITY HEREIN AND DO FURTHER CONSENT TO THE RELEASE OF ANY PERSON
      LIABLE WITH RESPECT TO FAILURE TO GIVE SUCH NOTICE, (ALL WITHOUT AFFECTING
      THE
      LIABILITY OF THE OTHER PERSONS, FIRMS, OR CORPORATIONS LIABLE FOR THE PAYMENT
      OF
      THIS NOTE).

    

    TO
      THE
      FULLEST EXTENT PERMITTED BY APPLICABLE LAW, THE MAKER HEREBY KNOWINGLY AND
      VOLUNTARILY WAIVES TRIAL BY JURY AND THE RIGHT THERETO IN ANY ACTION OR
      PROCEEDING OF ANY KIND ARISING UNDER OR OUT OF OR OTHERWISE RELATED TO OR
      CONNECTED WITH THIS NOTE OR ANY RELATED DOCUMENT.

    FOR
      VALUE RECEIVED,
      Travel
      Hunt Holdings, Inc., a Delaware corporation (the “Maker”), unconditionally
      promises to pay to the order of La Pergola Investments Limited, having an
      address at 1
      Portman
      House, Hue Street St. Helier, Jersey, Channel Islands JE4 5RP (the
      “Payee”), the principal sum of Ninety Nine Thousand Dollars ($99,000),
at
      a
      simple interest rate of two and one-half percent
      (2.5%) per
      annum
      computed on the basis of a 360 day year. The
      Maker
      further agrees to pay all costs of collection, including reasonable attorneys’
fees, incurred by the Payee or by any other holder of this Promissory Note
      (this
“Note”) in any action to collect this Note, whether or not suit is
      brought.

    

    Principal
      and accrued interest shall be payable on September 30, 2008 (“Maturity”), except
      that this
      Note
      shall accelerate upon
      the
Maker’s
      consummation of a private placement transaction (the “Financing”) in which it
      sells or issues shares of its common stock in a manner that is exempt from
      the
      registration requirements of the Securities Act of 1933, as amended, where
      the
      gross proceeds to the Maker of such Financing are at least $1,000,000 and in
      such event (an “Acceleration Event”) the principal and accrued interest shall be
      payable upon the consummation of such Financing.
      The
      proceeds of the Financing shall not be used for any purpose until the Maker
      pays
      all amounts due under this Note from such proceeds. The Maker shall have the
      right at any time to prepay, in whole, but not in part, the principal and
      accrued interest without penalty or notice to the Payee.
      If, but
      only if, the principal and accrued interest on this Note is not paid in full
      at
      Maturity or upon an Acceleration Event, or an Event of Default, then this Note
      shall become convertible into a number of shares of the Common Stock of the
      Maker that is equal to two and 25/100 percent (2.25%) of the outstanding Common
      Stock of the Maker on a fully-diluted, post-issuance basis (the “Conversion
      Shares”). In order to convert this Note into Conversion Shares, the Payee must
      demand conversion in writing within the ninety (90) day period following
      Maturity, an Acceleration Event, or an Event of Default. The Conversion Option
      shall only be exercisable in the event that this Note is not paid in full on
      or
      prior to Maturity, an Acceleration Event or an Event of Default. Notwithstanding
      the foregoing, if, at the time that this Note becomes convertible, there is
      insufficient authorized shares of the Maker’s Common Stock available for
      issuance to the Payee upon conversion hereof, then the Maker shall be obligated
      to use its best efforts to promptly amend its certificate of incorporation
      to
      authorize additional shares of its Common Stock such that all of the Conversion
      Shares may be issued upon conversion of this Note and, if this Note becomes
      convertible at a time when there is insufficient authorized Common Stock, then
      the Maker shall not be permitted to convert this Note until there is sufficient
      authorized Common Stock of Maker and the ninety (90) day period referred to
      above shall be tolled until such time as there is sufficient authorized Common
      Stock of Maker. The Company shall use its best efforts to increase its
      authorized capital stock as soon as practicable, but in any even within ninety
      (90) days, so that there will be sufficient authorized shares of capital stock
      to permit the conversion of this Note.

    

    The
      amounts due hereunder are payable without deduction or offset in lawful money
      of
      the United States of America in immediately available funds to the Payee at
      its
      address as set forth above, or at such other place as the Payee shall from
      time
      to time designate. 

    

    It
      shall
      be an event of default (“Event of Default”), and the then unpaid portion of this
      Note shall become immediately due and payable, at the election of Payee, upon
      the occurrence of any of the following events:

     

    (a) any
      failure on the part of the Maker to make any payment hereunder when due, whether
      by the occurrence of an Acceleration Event or otherwise;

    

    (b) The
      Maker
      shall commence (or take any action for the purpose of commencing) any proceeding
      under any bankruptcy, reorganization, arrangement, readjustment of debt,
      moratorium or similar law or statute; or

    

    (c) a
      proceeding shall be commenced against the Maker under any bankruptcy,
      reorganization, arrangement, readjustment of debt, moratorium or similar law
      or
      statute and relief is ordered against the Maker, or the proceeding is
      controverted but is not dismissed within sixty (60) days after the commencement
      thereof.

    

    No
      failure on the part of the Payee or any other holder of this Note to exercise
      and no delay in exercising any right, remedy or power hereunder or under any
      other document or agreement executed in connection herewith shall operate as
      a
      waiver thereof, nor shall any single or partial exercise by the Payee or any
      other holder of this Note of any right, remedy or power hereunder preclude
      any
      other or future exercise of any other right, remedy or power.

    
      
         

      

      
        
        

        
          

        

      

      
         

      

    

     

    This
      Note
      shall be binding upon the Maker and the Maker’s successors and
      assigns.

    

    This
      Note
      shall be governed by and construed in accordance with the laws of the State
      of
      New York, excluding the conflicts of laws principles thereof.

    

    In
      the
      event that any one or more of the provisions of this Note shall for any reason
      be held to be invalid, illegal or unenforceable, in whole or in part, or in
      any
      respect, or in the event that any one or more of the provisions of this Note
      shall operate, or would prospectively operate, to invalidate this Note, then,
      and in any such event, such provision or provisions only shall be deemed null
      and void and of no force or effect and shall not affect any other provision
      of
      this Note, and the remaining provisions of this Note shall remain operative
      and
      in full force and effect, shall be valid, legal and enforceable, and shall
      in no
      way be affected, prejudiced or disturbed thereby.

    

    All
      agreements between the Maker and the Payee are hereby expressly limited so
      that
      in no event whatsoever, whether by reason of deferment in accordance with this
      Note or under any agreement or by virtue of the Maturity of the Note or the
      occurrence of an Acceleration Event, or otherwise, shall the amount paid or
      agreed to be paid to the Payee hereunder or to compensate Payee for damages
      to
      be suffered by reason of a late payment hereof, exceed the maximum permissible
      under applicable law. If enforcement of any provision hereof at the time
      performance of such provision shall be due, shall exceed the limit of validity
      prescribed by law, the relevant obligations to be fulfilled shall be deemed
      reduced to the limit of such validity. This provision shall never be superseded
      or waived and shall control every other provision of all agreements between
      the
      Maker and the Payee. 

    

    Subject
      to the applicable cure periods contained herein, time is of the essence of
      this
      Note. 

    

    EXCEPT
      AS
      OTHERWISE SPECIFICALLY PROVIDED HEREIN, THE MAKER, AND ALL OTHERS THAT MAY
      BECOME LIABLE FOR ALL OR ANY PART OF THE OBLIGATIONS EVIDENCED BY THIS NOTE,
      HEREBY WAIVES PRESENTMENT, DEMAND, NOTICE OF NONPAYMENT, PROTEST AND ALL OTHER
      DEMANDS AND NOTICES IN CONNECTION WITH THE DELIVERY, ACCEPTANCE, PERFORMANCE
      OR
      ENFORCEMENT OF THIS NOTE, AND DOES HEREBY CONSENT TO ANY NUMBER OF RENEWALS
      OR
      EXTENSIONS OF THE TIME OF PAYMENT HEREOF AND AGREE THAT ANY SUCH RENEWALS OR
      EXTENSIONS MAY BE MADE WITHOUT NOTICE TO ANY SUCH PERSONS AND WITHOUT AFFECTING
      THEIR LIABILITY HEREIN AND DO FURTHER CONSENT TO THE RELEASE OF ANY PERSON
      LIABLE WITH RESPECT TO FAILURE TO GIVE SUCH NOTICE, (ALL WITHOUT AFFECTING
      THE
      LIABILITY OF THE OTHER PERSONS, FIRMS, OR CORPORATIONS LIABLE FOR THE PAYMENT
      OF
      THIS NOTE).

    

    TO
      THE
      FULLEST EXTENT PERMITTED BY APPLICABLE LAW, THE MAKER HEREBY KNOWINGLY AND
      VOLUNTARILY WAIVES TRIAL BY JURY AND THE RIGHT THERETO IN ANY ACTION OR
      PROCEEDING OF ANY KIND ARISING UNDER OR OUT OF OR OTHERWISE RELATED TO OR
      CONNECTED WITH THIS NOTE OR ANY RELATED DOCUMENT.
