D. WHEREAS the CONTRACTING PARTIES wish to enter into and celebrate an Agreement
for the Assignment and Transfer of Mineral Rights and for such purpose SUPPLY

celebrate this "MEMORANDUM OF UNDERSTANDING", according to the following terms
and conditions:

newspaper.

1.3 The GARIMPEIROS, as from the date of the execution hereof and for a period
of 90 (ninety) days, undertake not to assign, transfer, encumber or lien the

visits, examine the data and decide to exercise its option to acquire the

2.2 The GARIMPEIROS agree to, immediately after SUPPLY confirms the interest
over the Mineral Rights comprised in the GARIMPO, assign and transfer the said
rights, upon payment (I) which will take place with the registration of the
transferred right and upon confirmation of its priority, which shall permit
SUPPLY to execute in the GARIMPO for a period of 42 (forty-two) 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 therefore, its interest in purchasing or not the
respective mineral rights. It should be noted that during the geological
assessment of the GARIMPO, the GARIMPEIROS may develop works therein provided
that work in the said mining site does not interfere with SUPPLY's research
activities, in which case the miners will need to stop their

                                        3

work. Whenever necessary, or as far as possible, SUPPLY will guide the
GARIMPEIROS as to how their work may be carried out to avoid stoppage.

2.3 All the productive activities are concentrated in a segment of the Highway
63 which links the cities of Cuiaba and Santarem, comprising the area of
interest of the CONTRACTING PARTIES. Therefore, the Parties shall take all the
necessary actions, jointly or separately and in the most convenient way to
defend the interests of the GARIMPO. Regarding the ownership, the GARIMPEIROS
declares to be the legitimate and sole owners of the areas comprising the
GARIMPO, and therefore, the mining results, right to rental or any
indemnifications are included in the prices established in clause 2.1 above. For
such purpose, the GARIMPEIROS agree to the best of their ability to provide to
SUPPLY with technical, legal and operational support, as well as undertake to
endeavour their best efforts to give SUPPLY any information it might have access
to with respect to the GARIMPO, and to take all actions necessary for the
expeditious registration of the documents needed in order for the Agreement to
be implemented, with SUPPLY being responsible for the financial expenses
incurred to obtain such results.

2.4 After the registration of the Exploration Agreement, SUPPLY may transfer to
any third parties, the mineral rights granted to it under this Agreement,
provided there is an inclusion of a clause in this regard.

2.5 At any time before the Option exercise, SUPPLY will be entitled to terminate
the Agreement and drop the GARIMPO PROJECT regardless of the motive, being
henceforth free of any and all payment commitments yet to be due. If SUPPLY
decides to exercise its option to terminate the agreement, it shall assign back
to the GARIMPEIROS within 15 days the Mining Rights object of this agreement
together with a detailed technical report which shall include all and any
information gathered to date.

2.6 The CONTRACTING PARTIES will be liable for a jointly follow-up before the
DNPM in regard to the Mineral Rights comprised in the GARIMPO, especially
regarding exploration permit requests, with all the expenses incurred of the
responsibility of SUPPLY.

2.7 Each of the CONTRACTING PARTIES herein will be liable for any and all
environmental damages resulting from their activities carried out in the
