subject to clauses 10.2(b) and (c), Otto and Irie will be severally liable for payment of the Haimila Royalty in amounts proportional to the percentage interest held respectively by (as applicable):

11.

REORGANISATION OF THE SANTA ROSA PROJECT

11.1

The Parties agree that, provided:

(a)

it is legally possible under Argentinean law to do so; and

(b)

Otto
  is not then in default of its obligations under this Agreement
   and/or the Shareholders Agreement ,

Otto may,
   but is under no obligation to,
  during the Pre JOA Period and at any time after Completion, give written notice to Irie, EO and Cynthia that Otto has elected to take a direct interest in the Contract (Reorganisation).

21



For the avoidance of doubt, nothing in this clause
   11.2 obliges EO to continue with Reorganisation if EO is required to accept a revised

  Contract
   which is in existence immediately prior to Reorganisation being initiated.

11.3

Immediately upon procuring each approval in clause 11.2, the relevant Party must furnish to each other Party documents evidencing that such approval has been
  procured.
   Immediately after the last of these approvals have been obtained, Otto must provide notice in writing to Irie, with a copy to Oromin, that the Reorganisation Completion will proceed (

   ).

  the Joint Operating Agreement must take effect from the Reorganisation Completion.

12.3

The obligation of EO at Reorganisation

  is to transfer to Otto (or its nominee) good title to a direct percentage interest in the Contract equivalent to the percentage interest held by Otto in Cynthia at the time of the Reorganisation in consideration for Otto paying EO US$1. Accordingly, and without limitation,

  must deliver or cause to be delivered to Otto
   at Reorganisation Completion:

(a)

the authorization of the transfer by the relevant enforcing authority;

(b)

the
   resolution of the EO Board granting the

12.7

Each of Oromin, Cynthia, Irie, Otto and EO have consented to, and, at Ottos sole expense, will take all steps necessary to effect, the Reorganisation, including by procuring any company which they each control take all necessary steps as soon as reasonably practicable after the Reorganisation Notice has been issued to effect the Reorganisation. In respect of all reasonable costs incurred by Oromin, Cynthia, Irie or EO to effect the Reorganisation (Reorganisation Costs):

(a)

subject to clause 12.7(b), Otto must promptly reimburse Oromin, Cynthia, Irie or EO (as applicable) for all Reorganisation Costs provided that Oromin, Cynthia, Irie or EO (as applicable) provide all relevant receipts and tax invoices to Otto within 60 Days of Reorganisation Completion (Reorganisation Invoices);

(b)

Otto may inspect the Reorganisation Invoices, and, if Otto (acting reasonably) deems it appropriate, Otto at its cost may elect to appoint an independent auditor to review the Reorganisation Costs incurred. If the independent auditor verifies the Reorganisation Costs against the Reorganisation Invoices, Otto must promptly pay the Reorganisation Costs in accordance with clause 12.7(a). Otherwise, if Oromin, Cynthia, Irie or EO (as applicable) disagree with the amount to be paid as determined by the independent auditor, the Parties must endeavour to agree the amount of Reorganisation Costs to be paid by Otto. If agreement of such amount cannot be reached within 10 Business Days of the decision by the independent auditor, the Parties (at the equal cost of Oromin and Otto) must appoint an independent expert to promptly determine the Reorganisation Costs to be paid. The decision of the independent expert will be final and binding.

update all public and private registers and records relating to the Contract to reflect it being jointly held by EO and the Otto Subsidiary in the correct proportions; and

assign to the Otto Subsidiary by public deed the relevant participating interest in all contracts, agreements and other arrangements (Arrangements) previously entered into by EO alone
   in relation to the Santa Rosa Project

WARRANTY ISSUES



AFIP Issue



On 1 March 2007 Raúl Bonfada filed with AFIP a Payment Plan A 492131 - Type of Plan 071 (Payment Plan) in order to pay the Assumed/Estimated Minimum Income Tax for fiscal years 2000/2001/2002/2003/2004/2005/2006/2007. EO paid to AFIP the "Assumed/Estimated Minimum Income Tax" for those fiscal years in one lump payment.

EO subsequently learnt from AFIP that the Payment Plan contained mistakes in the imputation of payments. Raúl Bonfada put in the field "Concept" the words "Advance Payments" and in the field "Subconcept" the word "Receivable Interest". Mr. Bonfada should have put in both of these fields the word "Affidavit".

Because of these mistakes in the tax returns declaration on the web, AFIP considers that EO did not pay the Assumed/Estimated Minimum Income Tax for fiscal year 2003 and has notified EO that it has to pay again. Bouzat lawyers went to the AFIP office and met with the official in charge of EO's account. The relevant official informed Mr. Bouzat that EO should pay the Assumed/Estimated Minimum Income Tax for fiscal year 2003 again and then file for a reimbursement of the sums paid in excess.

Bouzat lawyers answered the lawsuit in court showing that, although there were mistakes in the concepts and subconcepts in the filing with AFIP, EO had already paid the Assumed/Estimated Minimum Income Tax for fiscal year 2003 and complied with the obligation notified by AFIP.

There is a possibility that AFIP will also ask EO to pay again all or any of years 2000, 2001, 2002, 2004, 2005, 2006 and 2007.



Bouzat lawyers met with AFIP officials, lawyers and the Prosecutor in Court on 2 December 2008 and concluded that it is possible that the Judge will decide that AFIP has the right to collect the Assumed/Estimated Minimum Income Tax again. If that is the final ruling, EO would have to pay again Assumed/Estimated Minimum Income Tax for fiscal year 2003 and then immediately file for reimbursement of Assumed/Estimated Minimum Income Tax payment for fiscal year 2003 made on 1 March 2007 by Raúl Bonfada.





Central Bank Notice Issue



In 2003 the Argentine Government imposed a restrictive exchange system with regard to all transactions involving inflows and/or outflows of funds to and from Argentina.

The import of funds into Argentina by foreign investors for the purpose of making direct investments is exempted from certain of these foreign exchange restrictions (particularly, the mandatory deposit established by Decree 616/05 and supplementary rules). However, for such exemptions to be effective certain requirements must be met.

E-451

---





EO required money from Oromin in Canada to pay the Assumed/Estimated Minimum Income Tax for fiscal years 2000/2001/2002/2003/2004/2005/2006/2007 and obtain a fiscal certificate from AFIP. In order to allow the inflow of funds from abroad and to avoid the non-remunerated mandatory deposit (amounting to 30% of the funds brought into the country) EO decided to use the increase of capital exemption.

EO increased its corporate capital and filed all the legal and tax/accounting documents required by law with the GIC. Raul Bonfada, as accountant of EO, prepared the mandatory accountant/tax schedules and charts to be filed with the GIC.

The GIC notified EO that the mandatory accountant/tax schedules and charts were incorrect and had not been approved, Therefore the increase of capital filing needed to be corrected and was not going to be registered. Julio Pulisich prepared the new accountant/tax schedules and charts correcting the former ones made by Raul Bonfada.

EO filed the amended documents with the GIC. However two weeks ago EO received notice from Argentine Central Bank that it had to deposit a "non-remunerated mandatory deposit" of US$ 70,000 in an Argentine Central Bank account. Such deposit cannot be used for one year after it has been deposited and then it will be returned to EO. EO met with inspectors at the GIC and the increase of capital filing is going to be registered approximately in 10 Days.

Once the increase of capital filing is registered with the GIC, EO will meet with Central Bank officials and show evidence that all the requirements of the increase of capital exemption have been complied with so that the non-remunerated mandatory deposit should no longer be required.

At this time, Argentine Central Bank might decide to nevertheless still require EO to deposit the "non-remunerated mandatory deposit" of US$ 70,000 as EO exceeded the time allowed by law to complete the increase of capital exemption.
