<PAGE>
survey, explore and make economic use of the gold mineral reserves which may
eventually exist therein.

D. The LICENSEE signed and celebrated a Memorandum of Understanding on
05SEP2005, hereinafter referred to as "MOU", whereby the LICENSEE allowed Supply
Consult, a company with its Head Office in Germany at Karolinen Platz 5,
Muenchen, hereinafter referred to as "SUPPLY", the rights to survey and acquire
the mineral rights of "Garimpo Novo Porto", against payments, calculated and due
under the terms and conditions indicated and declared therein;

E. AURORA received from Supply the information regarding the potential primary
gold in "Garimpo Novo Porto" and believes possible the existence of primary
minerals and, therefore, is interested in acquiring the pertinent mineral
rights;

F. Supply resolved to transfer to AURORA the rights which have been conferred
upon Supply by the LICENSEE in the MOU, which the latter agrees to;

Therefore, AURORA and LICENSEE agree to execute a definitive agreement whereby
the conditions, amounts, deadlines and other clauses and conditions shall be
established and which shall hereon be in force between the parties hereby
present, and in this regard, the parties, AURORA and LICENSEE, agree to the
following:

I.   ASSESSMENT OF GARIMPO NOVO PORTO

1. The LICENSEE, hereby and in the best form of the law, permits AURORA to
execute in "Garimpo Novo Porto", for a period of 41 (forty-one) months as from
the date of this agreement, assessment work and geological survey which it deems
necessary to ascertain the existence of possible primary deposits which may be
economically explored and, consequently its interest in definitively acquiring
or not the respective mineral rights and the properties in question; (the
"Assessment").

2. It shall be up to AURORA to determine the nature, scope and extension of the
survey works, and thus, all costs and expenses incurred therein are of its
exclusive responsibility.

3. For the purposes of assuring a good execution of the assessment, the
LICENSEE:
a) Grants AURORA the right to occupy any of the surface areas of "Garimpo Novo
Porto" which possession he declares to have, free of claims from third parties,
and AURORA is assured that in case it cannot exercise its rights due to eventual
problems with above ground occupiers, it is hereby authorized by the LICENSEE to
take legal action in this regard, and eventual expenses or compensations paid to
them shall be deducted from the payments stipulated herein.

b) Authorizes AURORA to use the landing strip for airplanes and, if needed, to
alter its outline and access roads, facilities and other improvements therein
existing, and in this regard the parties shall sign a term of responsibility
and/or a "loan for use".

c) Shall prepare a survey of the persons involved in the mining works at
"Garimpo Novo Porto" and will present to AURORA a complete report within 90
(ninety) days from AURORA's request,

                                        2
<PAGE>
but AURORA is assured that in case it cannot exercise its rights due to eventual
problems with miners, it is hereby authorized by the LICENSEE to take legal
action in this regard, and eventual expenses or compensations paid to them shall
be deducted from the payments stipulated herein.

d) AURORA acknowledges that the above ground areas of "Garimpo Novo Porto" do
not include the totality of the mineral rights referred to in BLOCK I,
therefore, in case AURORA cannot exercise its rights due to eventual problems
with ground occupiers, the actions resulting thereof are the responsibility of
AURORA, although the LICENSEE shall assist in whatever possible.

e) in the surface areas of "Garimpo Novo Porto" included in the mineral rights
referred to in BLOCK I, the LICENSEE may not have its portions deducted under
the terms of item c above, since at any time it can deliver the same areas to
AURORA free and unencumbered without miners or ground occupiers.

4. The LICENSEE agrees to transfer the mineral rights in "Garimpo Novo Porto"
referred to in the survey requests to AURORA GOLD MINERACAO LTDA., as soon as it
is incorporated; meanwhile, the Requests for Mining Permission shall be
transferred to VERA LUCIA LOPES FERRAZ, Brazilian, married, businesswoman,
registered with CPF under No. 600.396.207-00, ID number RG 1816002 IFP/RJ, with
address at Rua Barra do Mendes, no. 245, casa 01, RJ, CEP 22753-040,  under the
terms of annex B 1 and 2, and the transferee, in the condition of depository,
shall be the titleholder until when these rights can be transferred to AURORA,
according to clause 10, item b below, with the mineral rights to be kept in
order and good condition until they can be assigned to AURORA or eventually
returned to the LICENSEE, all this in the manner hereunder stipulated. In
consideration for the authorization hereby granted to proceed with the
Assessment of "Garimpo Novo Porto" and in terms of price, AURORA shall pay to
the LICENSEE individually for the assignment of the mineral rights and rights of
possession over their surface areas according to items A and B above:

signing of this instrument;
b)     US$ 10,000.00 (ten thousand dollars) on 15 JAN 2006, provided AURORA

without any fault or pending issue which affect them negatively;
c)     US$ 37,500.00 (thirty-seven thousand five hundred dollars) on 30 MAY
2006, and provided that the approval of the assignments has been published at

and within the referred period, the above-mentioned payment is to be suspended
and shall be paid within 5 (five) days upon total compliance with such
stipulations;
d)     US$ 50,000.00 (fifty thousand dollars) on 30 MAY 2007, and provided that

occupier other than the LICENSEE is found in those areas, the LICENSEE, in view
of the Block in question, shall obtain for AURORA access to survey and the right
to mining without onus; on the contrary, AURORA may take legal action in this
regard and deduct all and any expense which it may incur from the above referred
