    This

herein individually as a “Party” or collectively as the “Parties.”

    

    For good
consideration received and acknowledged herein, and in consideration of the
respective covenants and agreements herein and
according to Article 2.12 of the Agreement for Exclusive Dealing and Letter of
Intent between the Parties dated November 26, 2009 (the “Agreement”), the
Parties agree as follows.

    

    1.           Amendment. Article
2.3 of the Agreement shall be stricken in its entirety and replaced with the
following:

    
       

      
        
          
            
              
                
                  
                    
                      
                        
                          
                            
                              
                                
                                  	
                                          “Term of this
      LOI. Unless otherwise extended by mutual written agreement of the
      Parties, this LOI shall terminate at midnight local time in Houston, Texas
      on March 11, 2010, unless the mutually agreed and duly authorized
      Definitive Agreements have been executed, whichever occurs first, such
      date of termination being herein referred to as the “Termination
      Date”.

                                        

                                

                              

                               

                            

                          

                        

                      

                    

                  

                

              

            

          

        

      

    

    2.           Payments.

     

    

    (a)           No
later than ten (10) Working days following the Effective Date, Repsol agrees
that it shall make a wire transfer of US$ $2,726,416.45
to HDY which payment shall constitute and shall be deemed to constitute Repsol’s
pro-rata share of obligations to acquire rights and interests in and under the
Marine 2D Seismic Data Acquisition Services Agreement with Bergen Oilfield
Services AS dated September 29, 2009, (the “BOS Agreement”).

    

    (b)           No
later than fifteen (15) Working days following the HDY’s delivery of an invoice
to Repsol for subsequent work performed under the BOS Agreement, including BOS’s
completion of seismic acquisition in the Contract Area pursuant to the BOS
Agreement, Repsol agrees that it shall make a wire transfer to HDY of its
pro-rata share of such invoice, which is currently estimated to be US$1,000,000
in satisfaction of Repsol’s pro-rata obligations to acquire rights and interests
to the additional seismic data covered by the invoice under the BOS
Agreement.

     

    HDY shall at all times indemnify and
hold harmless Repsol, its employees, officers and agents, against any and
all damages, liabilities, costs and expenses (including documented legal fees
and expenses) arising out or resulting from any third party claims and/or as a
consequence of any violation or breach of the BOS Agreement.

     

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

     

    Upon the payments described in (a) and
(b) above, Repsol will have the rights regarding the aforementioned data except
for resale or delivery to third parties; and, in the event the PSC Clarification
is not duly ratified prior to September 10, 2010, no further payments shall be
due pursuant to this Article 2 and HDY will reimburse Repsol for any payments
already made pursuant to this Article 2 within ten (10) Working days after the
request made by Repsol at its sole discretion.

     

    3.           Taxes.

     

    (a) All taxes levied or imposed, now or
in the future, by any Taxing Authority on the signature or on the performance of
the obligations under this Amendment shall be borne by the Party which is liable
according to the applicable law and the Tax Convention to avoid Double Taxation
in force between Spain and United States of America. The amounts provided in
Article 2 of this Amendment shall be grossed up to account for any taxes owed
such that the net figure paid to HDY shall not be diminished.

     

    (b) Prior to payment of the first
invoice described in Article 2.(a) of this Amendment HDY shall provide Repsol
with original Certificate of Residence issued by local United States Tax
Authorities within the meaning of Article 4 of United States and Spain Tax
Convention to avoid Double Taxation. Such certificate shall be valid for one (1)
year from its issuance.

     

    4.           Notices.  All
notices and communications required or permitted under this Amendment shall be
in accordance with Article 2.15 of the Agreement.

    

    5.           Confidentiality.  This
Amendment shall be subject to the provisions of Article 2.5 of the
Agreement.

    

    6.           Counterparts.  This
Amendment may be executed by the Parties in any number of counterparts, each of
which shall be deemed an original instrument, but all of which together shall
constitute but one and the same instrument.  Facsimile signatures
shall be considered binding.

     

    7.           Applicable
Law.  This
Amendment and the transactions contemplated herein shall be construed in
accordance with Article 2.8 of the Agreement.

     

    8.           Entire
Agreement. This
Amendment constitutes the entire understanding among the Parties with respect to
the subject matter hereof, superseding all negotiations, prior discussions and
prior agreements and understandings relating to such subject matter. Except as
specifically amended hereby, all the remaining conditions of the Agreement shall
remain in full force and effect.

     

    
      
        
        

      

      
        2
