referred in the following paragraph) to be made by VOTORANTIM, in exchange of
shares representing an overall 15% participating interest in CHAMBARA.

Such contribution shall be approved by CHAMBARA's Shareholders' Meeting, either
as a result of VOTORANTIM directly contributing the VOTORANTIM Properties to

Properties will be transferred for the benefit of CHAMBARA and will subsequently

receives from CHAMBARA copy of the certificates issued by the Public Registry
evidencing the recording of all of the Properties under the name of CHAMBARA,
MINERA SOLITARIO will cause CHAMBARA to execute a Mining Assignment Agreement
over the Properties for the term necessary for VOTORANTIM to be allowed to make
the decisions that will allow it to deliver to MINERA SOLITARIO the notices
referred to in sections 7.3.2 and 7.3.3.

Said Mining Assignment Agreement, which is made an integral part hereof as Annex

payment will be made through the delivery of a certified check issued in favor
of CHAMBARA, concurrently with the execution of the Mining Assignment
Agreement's public deed.

<PAGE>

6.3     During the term of the Mining Assignment Agreement, VOTORANTIM will be
responsible for the activities conducted at the Properties.

6.4     During the term of the Mining Assignment Agreement, VOTORANTIM may
perform any and all prospecting, exploration and assessment works that it may
deem appropriate, with no limitation whatsoever, provided that it will be the
only Party entitled to carry out activities related to the Properties.

6.5     VOTORANTIM will be entitled to take from the Properties mineral and
metallic samples with the sole purpose of making tests and assays as well as to
build, bring to and install therein any and all buildings, machinery, equipment
and supplies which, at its discretion, may be deemed required and appropriate to
carry out the activities described in sections 6.6 and 6.7.

6.6     In general terms, CHAMBARA shall grant VOTORANTIM during the effective
term of the Mining Assignment Agreement, but not limited to, the following
rights and faculties:

a.     The right to enter into the Properties and use any and all the rights of
way and access means.

b.     To perform prospecting, exploration and assessment activities, using any
method known at present or which may be developed in the future.

c.     To build, use, maintain, repair, relocate or replace roads, drilling
sites, buildings, fences, power and communication lines, structures, camps,
field offices and other facilities or infrastructure which may be helpful or
which may be appropriate for VOTORANTIM in the performance of its exploration
activities.

d.     To extract and remove from the Properties non-commercial quantities of
ore, with the purpose of testing them (including, but not limited to, bulk
samples, tests, geo-chemical analysis, the possibility of being taken to
crushers and the determination of the recovery, pilot plants, test operations or
similar activities). The exercise of this right does not involve the obligation
to make any payment to CHAMBARA.

e.     The right to use water rights related to the Properties in relation to
the performance of exploration activities.

f.     To exercise any and all the rights that may be attached or usually
related to the activities related to the rights granted, expressly or
implicitly, to VOTORANTIM hereunder.

6.7     In its capacity of mining assignee of the Properties, VOTORANTIM hereby
undertakes the following obligations:

6.7.1     To carry out any and all works at the Properties in a way consistent
with good exploration practices and high professional standards for said
activities, complying with all the applicable laws and regulations, without
limitation, holding harmless MINERA SOLITARIO from any and all the claims that
may arise as the result of the activities conducted by VOTORANTIM in the
Properties;

6.7.2     Allow MINERA SOLITARIO the unrestrictive access to the Properties and
to all the records kept by VOTORANTIM, at its own risk and cost. With respect
thereof, VOTORANTIM shall maintain proper and complete records and accounts of
all the expenditures and works made with regard to the Properties, in accordance
with accounting principles and standards generally accepted in the mining
industry and applicable law. Such records and accounts shall be made available
for MINERA SOLITARIO's review and audit at any time the latter requests them,
provided that the costs of any such review or audit will be assumed entirely by
MINERA SOLITARIO.

Likewise, VOTORANTIM shall allow MINERA SOLITARIO to inspect the Properties at
its own risk and account, and abiding by reasonable safety standards, to the
extent deemed reasonable, on the understanding that the Party conducting such
inspection does not interfere excessively with VOTORANTIM's activities.

13

<PAGE>

6.7.3     Make timely and full payment of the Validity Fees for the Properties
or other fees or taxes that the federal or local governments shall impose in
relation to mineral, surface, water or other rights required to execute work
programs. In this sense, VOTORANTIM will be obliged to pay the Validity Fees of
the Properties for each year during which the Mining Assignment Agreement is in
force, provided that said fees shall be paid every year, with no delay.

Should the possession of the Properties, or any of them, be returned to CHAMBARA
as a consequence of the termination of the Mining Assignment Agreement, on the
effective date of termination of such document, no payment of the Validity Fees
in respect of the Properties shall be outstanding and the Validity Fees for all
years initiated prior to the effective date of return must be fully paid.

Within fifteen (15) calendar days as from the date in which the relevant
payments are made, VOTORANTIM shall forward a copy of the corresponding
supporting documents to CHAMBARA, provided, however, that said documents should
be delivered to CHAMBARA not less than fifteen (15) calendar days in advance to
the date on which under the laws in force at that time, payment of the Validity
Fees shall be timely made.

VOTORANTIM shall also make timely payments to local landowners or communities as
required by local ordinance or contract as may be needed for the use of surface
rights or ingress and egress. It is expressly established that should VOTORANTIM
elect to terminate this Agreement (and, thusly, the Mining Assignment Agreement
as established herein), that no payment of the Validity Fees for the Properties
or payments to local landowners or communities shall be outstanding, so that on
the effective date of termination, the Validity Fees corresponding to all the
years that may have began until the above mentioned effective date of
termination must be fully paid.

If it is not possible to make the payments directly to the administrative entity
that should receive them, they will be understood to be made at the time
VOTORANTIM delivers an amount equivalent to the same to CHAMBARA with reasonable
anticipation so that CHAMBARA can make such payments in a timely manner.

6.7.4   VOTORANTIM shall be responsible for filing the Annual Consolidated
Statement (DAC) corresponding to the Properties. Once the relevant filing has
been made, VOTORANTIM shall forward a copy of the filed documents to MINERA
SOLITARIO, provided, however, that said documents should be delivered to MINERA
SOLITARIO not less than fifteen (15) calendar days in advance to the date on
which under the laws in force at that time, the filing of the DAC shall be made.

6.7.5   VOTORANTIM hereby undertakes responsibility regarding the environmental
obligations that may arise from the mining activities conducted by it in the
Properties, and to carry out exploration works in a correct, diligent and
efficient manner in accordance with sound mining industry and environmental
protection standards and practices, and abiding by the terms and conditions of
the concessions, assignments, licenses, permits, contracts and other agreements
pertaining to the Properties.

With respect to the above, it is hereby agreed that VOTORANTIM shall not be
responsible for any environmental liabilities that are a result of the works
performed in the Properties pertaining to MINERA SOLITARIO prior to the Date of
Initiation of the Mining Assignment.

14

<PAGE>

6.7.6     VOTORANTIM shall be liable to MINERA SOLITARIO for any action or
inaction directly attributable to VOTORANTIM resulting in damages, losses,
expenses, penalties or fines. No default by VOTORANTIM of its obligations shall
be deemed to have occurred hereunder, if compliance therewith is rendered
impossible due to MINERA SOLITARIO's failure to perform acts required by this
Agreement.

Any environmental obligations or liabilities of VOTORANTIM hereunder and those
arising out of the application of the legal statutes and regulations applicable
to the activities that it shall conduct in the Properties, shall endure as a
Continuing Obligation after termination of the Mining Assignment Agreement.

6.8     During the term of the Mining Assignment Agreement, MINERA SOLITARIO
will make its best efforts to collaborate with VOTORANTIM in taking all
reasonable action to resolve any problems that could exist or arise with the
owners of the surface lands required for conducting mining activities with
regard to the Properties, and with small, artisan or illegal miners that could
be working in the area of the Properties.

With respect to the above, MINERA SOLITARIO will make its best efforts to assist
VOTORANTIM in its dealings and negotiations with any owners or occupiers of the
above mentioned surface lands, indigenous cultural communities or any other
person or entity that could be affected by VOTORANTIM's activities in the
Properties.

6.9     During the term of the Mining Assignment Agreement VOTORANTIM and MINERA
SOLITARIO shall convene quarterly meetings to review the results of the previous
quarter's exploration and development results, expenditures and plans for future
activities on the Property.  Such meetings shall be held in Lima, Peru at a time
convenient for the participants and may be held by telephone.

:          FIRST and SECOND OBLIGATIONS TO CAPITALIZE

7.1     Within ten (10) calendar days following the date of receipt of the
notice referred to in section 7.2 and as long as:

(i)     VOTORANTIM had timely and duly delivered said notice to MINERA
SOLITARIO;

(ii)     VOTORANTIM had timely and duly fulfilled the requirements set forth in
sections 7.3 and 7.4; and,

(iii)     VOTORANTIM is not in default of its obligations under the Mining
Assignment Agreement and, in general, under this Agreement;

MINERA SOLITARIO shall procure that CHAMBARA, by means of a Shareholders'
Meeting resolution, capitalizes a contribution to be made by VOTORANTIM referred
to in section 6.1 (the "FIRST OBLIGATION TO CAPITALIZE") of the expenditures
made in the completion of the Feasibility Study mentioned in section 7.3.3.1, or
in completing the overall and cumulative investment of Qualified Expenditures of
US$ 6.25 million in the Properties mentioned in section 7.3.3.2, as the case may
be; this Feasibility Study and/or the technical reports and other assets or
outstanding debts before CHAMBARA obtained and/or registered by VOTORANTIM as a
result of its exploration activities in the Properties during the term beginning
at the Date of Initiation of the Mining Assignment and ending at the date in
which the notice referred to in section 7.2 is received by MINERA SOLITARIO.

        Such capitalization will be agreed by CHAMBARA's Shareholders' Meeting
either as a result of VOTORANTIM directly contributing those assets to
CHAMBARA's capital stock, as a result of the capitalization of the credits owed
to VOTORANTIM by CHAMBARA following the latter's purchase of the same assets
from VOTORANTIM, or in any other way deemed convenient. Accordingly, the Parties
agree that the mechanism through which the aforesaid assets will be transferred
for the benefit of CHAMBARA and will subsequently allow VOTORANTIM to earn-in
the shareholding interest in CHAMBARA

15

<PAGE>

referred to in this section, will be determined by considering the most tax
efficient method taking into account the interests of all of the Parties.

As a result of the contribution and the recording in the books of CHAMBARA as
Initial Capital the expenditures of VOTORANTIM during the period beginning at
the Date of Initiation of the Mining Assignment and ending at the date in which
the notice referred to in section 7.2 is received by MINERA SOLITARIO (this is,
after fulfillment of the provisions of sections 7.3 and 7.4 has been met),
VOTORANTIM will receive shares issued by CHAMBARA equivalent to the following:

(a)     If VOTORANTIM had requested performance of the FIRST OBLIGATION TO
CAPITALIZE to MINERA SOLITARIO after having fulfilled only one of the conditions
set forth in sections 7.3.3.1 and 7.3.3.2, VOTORANTIM will receive shares issued
by CHAMBARA equivalent to 34% of CHAMBARA's capital stock, so that VOTORANTIM
holds at that time an aggregate 49% participating interest in CHAMBARA.

(b)     If VOTORANTIM had requested performance of the FIRST OBLIGATION TO
CAPITALIZE to MINERA SOLITARIO after having fulfilled both conditions set forth
in sections 7.3.3.1 and 7.3.3.2, VOTORANTIM will receive shares issued by
CHAMBARA equivalent to 55% of the latter's capital stock so that VOTORANTIM
holds at that time an aggregate 70% participating interest in CHAMBARA.

In this case, the SECOND OBLIGATION TO CAPITALIZE will extinguish as soon as
VOTORANTIM formalizes its title over shares equivalent to 70% CHAMBARA's
capital, as it will be deemed that VOTORANTIM had already complied with the
conditions set forth in section 7.5 for those effects.

        In the event that the contribution made by VOTORANTIM is valued and/or
represents more than a 34% or 55% interest in CHAMBARA (as the case may be),
VOTORANTIM will only receive additional shares representing such 34% or 55%
interest in CHAMBARA. The excess or difference between the value of the referred
investment made by VOTORANTIM and the shares' value subscribed and received by
VOTORANTIM in exchange, shall be deemed to be a capital premium for the benefit
of both Shareholders.

        Upon this initial capitalization, VOTORANTIM and MINERA SOLITARIO
(either through SOLITARIO PERU or SOLITARIO RESOURCES; thus, any reference made
herein to "MINERA SOLITARIO" in the specific context of the latter being
shareholder of CHAMBARA, shall be understood made to SOLITARIO PERU and
SOLITARIO RESOURCES) shall then be deemed to have made initial contributions to
the capital of CHAMBARA equal to their pro rata shareholding interests in the
proportion VOTORANTIM 49% and MINERA SOLITARIO 51%, or VOTORANTIM 70% and MINERA
SOLITARIO 30%, as the case may be, and such contributions to the capital shall
be recorded in the books of CHAMBARA accordingly.

7.2     Within a thirty (30) calendar days term counted as from the date in
which the conditions established in sections 7.3 and 7.4 are complied with,
VOTORANTIM may request MINERA SOLITARIO, through the delivery of a notarized
letter, to perform the FIRST OBLIGATION TO CAPITALIZE.

If the aforesaid notarized letter is not delivered and received by MINERA
SOLITARIO within the above mentioned term, then it will be deemed as if
VOTORANTIM had waived its right to request performance by MINERA SOLITARIO of
the FIRST OBLIGATION TO CAPITALIZE, in which case this Agreement will be
terminated and the appropriate provisions of section 22.1 shall apply. In this
case, the appropriate provisions set forth in clause twenty two will be
applicable.

16

<PAGE>

7.3     It is a condition for the enforceability of the FIRST OBLIGATION TO
CAPITALIZE that VOTORANTIM complies with the following:

7.3.1   Invest a total amount of Qualified Expenditures of US$ 500,000.00 (five
hundred thousand and 00/100 American Dollars) in exploration activities in the
Properties during the twelve (12) month period following the Date of Initiation
of the Mining Assignment.

It is hereby agreed that any excess of the Qualified Expenditures for the period
referred to in this section 7.3.1, will be applied to those indicated in section
7.4.

7.3.2   Notifying MINERA SOLITARIO in writing that it has decided to continue
making Qualified Expenditures, although now as per the schedule described in
section 7.4, in which case the provisions established in such section will
apply.

7.3.3   Notifying MINERA SOLITARIO in writing that it has either:

7.3.3.1     Completed and delivered to MINERA SOLITARIO a Feasibility Study
supporting the construction of a mining project over the Properties, in a form
that is customary for VOTORANTIM; or,

7.3.3.2     Completed an overall and cumulative investment of Qualified
Expenditures of US$ 6,250,000.00 in the Properties.

The notice referred to in this section 7.3.3, may be delivered by VOTORANTIM
upon verifying that any or both of the conditions stipulated in sections 7.3.3.1
or 7.3.3.2 have been met, whichever is verified first.

The Parties hereby declare and agree that, except for the completion of the
investments indicated in section 7.3.1, there is no given term agreed for
VOTORANTIM to deliver to MINERA SOLITARIO the notices mentioned in sections
7.3.2 and 7.3.3 above. Therefore, VOTORANTIM may take as much time as it
considers convenient in order to adopt the decisions and complete the works,
subject to expenditure schedule in section 7.4, that it might deem convenient,
in order to deliver the above mentioned notices.

7.4     As from the beginning of the second year following the Date of
Initiation of the Mining Assignment, VOTORANTIM will continue making Qualified
Expenditures in the Properties in accordance to the following schedule:

7.4.1   Investments of not less than US$ 750,000.00 (seven hundred and fifty
thousand and 00/100 American Dollars) in exploration and/or development
activities to be performed directly in the Properties, during the second twelve
(12) months following the Date of Initiation of the Mining Assignment.

7.4.2   Investing not less than US$ 1'000,000.00 (one million and 00/100
American Dollars) in exploration and/or development activities to be performed
directly in the Properties, during the third, fourth, fifth, sixth and seventh
twelve (12) month periods (cumulatively US$ 5,000,000 million) following the
Date of Initiation of the Mining Assignment.

VOTORANTIM will only be obliged to make the minimum investments referred to in
this section, until the date in which this Agreement is terminated under the
provisions of section 22.1 or VOTORANTIM has earned a 49% or a 70% shareholding
interest in CHAMBARA, as the case may be.

Any excess investment made by VOTORANTIM during any of the periods mentioned in
sections 7.4.1 and 7.4.2, shall be offset against the investment obligation
established for the following period. On the contrary, if VOTORANTIM does not
complete the committed investment for a given period, then VOTORANTIM shall, at
its discretion, fulfill one of the two following options in order to maintain
its rights under this Agreement:

17

<PAGE>

pay directly to the Party to this agreement nominated by MINERA SOLITARIO (as a
penalty) an amount equivalent to those outstanding investments, or

on a date not later than 15 calendar days prior to the end of a period deliver
to MINERA SOLITARIO written notice of a firm commitment to fulfill during the
next work commitment period both the uncompleted investment from the then
current period and the investment to be completed during the following work
commitment period. An uncompleted investment postponed until the following
period shall not exceed 20% of the work commitment for the period.

It is hereby expressly declared that the completion by VOTORANTIM of cumulative
investments in Qualified Expenditures for US$ 6,250,000.00 is not a condition
for the enforceability of the FIRST OBLIGATION TO CAPITALIZE for VOTORANTIM to
request MINERA SOLITARIO its fulfillment, if VOTORANTIM has previously completed
the preparation of a Feasibility Study as stipulated in section 7.3.3.1, and
vice versa. Therefore, it is hereby agreed that the prior completion of an
overall and cumulative investment in Qualified Expenditures for US$ 6'250,000.00
will not necessarily be a condition for VOTORANTIM to request performance by
MINERA SOLITARIO of the FIRST OBLIGATION TO CAPITALIZE.

However, if VOTORANTIM has not made cumulative investments in Qualified
Expenditures of US$ 6'250,000.00 upon the date of enforcement of the FIRST
OBLIGATION TO CAPITALIZE, then continued expenditures as defined in section 7.6
by CHAMBARA shall be funded 100% by VOTORANTIM until a total of US$ 6'250,000.00
has been funded by VOTORANTIM. Only after VOTORANTIM has fulfilled a cumulative
expenditure of US$ 6'250,000.00 and fulfilled the requirements of 7.3.3.1 and
7.3.3.2, shall MINERA SOLITARIO be required to participate in joint funding as
provided for in section 9.2.

7.5     If pursuant to section 7.1, VOTORANTIM had only earned-in a 49%
shareholding interest in CHAMBARA as a result of the former having fulfilled
only one of the conditions set forth in sections 7.3.3.1 and 7.3.3.2, MINERA
SOLITARIO will be irrevocably obliged to vote at CHAMBARA's Shareholders'
Meeting in favor of capitalizing the contributions to be made by VOTORANTIM of
all the assets or outstanding debts before CHAMBARA obtained and/or registered
by the latter as a result of its exploration activities in the Properties
conducted as from the date of receipt by MINERA SOLITARIO of the notice referred
to in section 7.2, and the date in which VOTORANTIM delivers to MINERA SOLITARIO
a notice informing that it has fulfilled whichever one of the conditions set
forth in sections 7.3.3.1 or 7.3.3.2 was pending of completion after performance
by MINERA SOLITARIO of the FIRST OBLIGATION TO CAPITALIZE (the "SECOND
OBLIGATION TO CAPITALIZE").

Such capitalization will be agreed by CHAMBARA's Shareholders' Meeting either as
a result of VOTORANTIM directly contributing those assets (which may include the
expenditures incurred in the preparation of the Feasibility Study referred to in
section 7.3.3.1 and this document, should that be the case, or the expenditures
required to complete an overall US$ 6.25 million investment of Qualified
Expenditures in the Properties mentioned in section 7.3.3.2, should that be the
case) to CHAMBARA's capital stock, as a result of the capitalization of the
credits owed to VOTORANTIM by CHAMBARA following the latter's purchase of the
same assets from VOTORANTIM, or in any other way deemed convenient. Accordingly,
the Parties agree that the mechanism through which the aforesaid assets will be
transferred for the benefit of CHAMBARA and will subsequently allow VOTORANTIM
to earn-in the additional shareholding interest in CHAMBARA referred to in this
section, will be determined by

18

<PAGE>

considering the most tax efficient method taking into account the interests of
all of the Parties and CHAMBARA.

As a result of the performance by MINERA SOLITARIO of the SECOND OBLIGATION TO
CAPITALIZE, VOTORANTIM will receive shares issued by CHAMBARA equivalent to 21%
of the latter's capital stock, and as a result of same VOTORANTIM will have
reached an aggregate 70% shareholding interest in CHAMBARA. In the event that
the contribution made by VOTORANTIM is valued and/or represents more than a 21%
interest in CHAMBARA, VOTORANTIM will only receive shares representing a 21%
interest in CHAMBARA. The excess or difference between the value of the assets
or credits subject of capitalization and the shares' value subscribed and
received by VOTORANTIM in exchange, shall be deemed to be a capital premium for
the benefit of both Shareholders.

Upon this capitalization VOTORANTIM and MINERA SOLITARIO shall then be deemed to
have made contributions to the capital of CHAMBARA equal to their pro rata
shareholding interests in the proportion VOTORANTIM 70% and MINERA SOLITARIO
30%.

MINERA SOLITARIO shall perform the SECOND OBLIGATION TO CAPITALIZE within ten
(10) calendar days following the date of receipt of the notarized notice
delivered by VOTORANTIM informing MINERA SOLITARIO that it has fulfilled
whichever one of the conditions set forth in sections 7.3.3.1 or 7.3.3.2 was
pending of completion after performance by MINERA SOLITARIO of the FIRST
OBLIGATION TO CAPITALIZE.

7.6     Qualified Expenditures

7.6.1   "Qualified Expenditures" are understood to be all costs, expenditures
and liabilities of any kind incurred in exploration activities on the Properties
or in benefit of the Properties during the term of the Mining Assignment
Agreement and will include the following, among others also defined as such in
this Agreement:

employees and contractors, material, equipment and supplies necessary for the
conduction of exploration activities;

(vi)    Any other payments to contractors for work on or for the benefit of the

necessary to commence, carry out or complete exploration, and otherwise spent on

laws and regulation;

(x)     Monies expended in performing pre feasibility or Feasibility Studies to

(xii)   Monies expended in performing socio-economic studies, payments to local
communities, and other social work related to local communities; and,

(xiii)  An amount equal to five percent (5%) of the Qualified Expenditures of
each period, for concept of administrative expenses. As from the date in which
VOTORANTIM has completed US$ 10,000,000.00 (ten million American Dollars) of
Qualified Expenditures (should that ever be the case), this amount will be
reduced to three percent (3%); and,

It is hereby established that the Value Added Tax (Impuesto General a las
Ventas), the Tax of Municipal Promotion (Impuesto de Promoción Municipal) and
any other tax levying sales or added value corresponding to the items referred
to in above, will be considered as part of the Qualified Expenditures.

7.6.2     Within fifteen (15) calendar days following:

(i)     the date on which VOTORANTIM determines that it has spent an overall and
cumulative investment of US$500,000.00 in Qualified Expenditures; and

(ii)     the end of each twelve (12) months period as of the date mentioned in
7.4.1 and 7.4.2 above;

(iii)    the date on which VOTORANTIM provides to MINERA SOLITARIO notice as
provided for in section 7.3.3 and, if having already provided such notice,
determines that it has spent an overall and cumulative investment of
US$6,250,000.00 in Qualified Expenditures;

VOTORANTIM shall submit to MINERA SOLITARIO a report describing in reasonable
detail the nature and amount of all expenses incurred by VOTORANTIM and deemed
by it to qualify as Qualified Expenditures, and a report on the results of the
activities conducted in the previous twelve (12) months, detailing the technical
relevant issues pertaining to each activity and the interpretive results,
conclusions and recommendations obtained as a consequence of those activities.

7.6.3   Within thirty (30) calendar days after receipt of the Qualified
Expenditures reports referred to in section 7.6.2(i), 7.6.2(ii) and 7.6.2(iii)
hereof, MINERA SOLITARIO shall give written notice to VOTORANTIM if it considers
that any of the expenses made by VOTORANTIM do not qualify as Qualified
Expenditures, and it shall support its observations in

20

<PAGE>

detail. If such term expires and MINERA SOLITARIO has not submitted any
observations to the Qualified Expenditures, the Qualified Expenditures submitted
by VOTORANTIM for such period shall be deemed approved. However, should MINERA
SOLITARIO request in writing that the period for review of a Qualified
Expenditures report such request shall be granted for a second period of thirty
(30) calendar days.

It is hereby understood that the Qualified Expenditures corresponding to such
periods which have already been subject to review and approval, shall not be
subject to further observations.

7.6.4   Upon receipt of MINERA SOLITARIO's observations, VOTORANTIM shall have a
fifteen (15) calendar day period to

(a)     Issue a reply in writing thereto giving an explanation of the
differences and detailing what observations made by MINERA SOLITARIO are
accepted, if any.

(b)     If there remain observations by MINERA SOLITARIO that are not accepted
by VOTORANTIM the latter will propose a time and a place acceptable to both
Parties to meet to discuss and resolve any unaccepted observations;

(c)     Pay CHAMBARA a cash amount equal to such amount as is required to
complete the relevant Qualified Expenditures for the term stipulated in section
7.3.1, in which case they shall be understood to have been completed. This
alternative is only applicable when verifying the Qualified Expenditures
described in the report mentioned in section 7.6.2(i) for determining whether
VOTORANTIM has completed the minimum investments indicated in section 7.3.1.

It is hereby understood that the above mentioned alternatives are not excluding,
and that two or three of them may be concurrently applied to different items.

If within the aforesaid fifteen (15) day term VOTORANTIM does not notify MINERA
SOLITARIO in writing as described in paragraphs (a) or (b), it shall be deemed
that VOTORANTIM has accepted the observations filed by MINERA SOLITARIO.
Therefore, the Qualified Expenditures disputed by MINERA SOLITARIO will not be
considered as such for the purposes of determining the amount of the investments
effectively made by VOTORANTIM within the term to which those investments
correspond.

If, in the case that the differences in the acceptance of Qualified Expenditures
cannot be resolved, any Party may call for the submission of the difference to
the decision of a consultant firm to be appointed by the mutual consent of the
Parties. This decision will be final and binding for the Parties, provided that
the fees of the consultant firm will be paid by the Party which position was
upheld in a lesser proportion of the Qualified Expenditures under dispute.

7.6.5   If upon verification of the investments described in the reports
mentioned in sections 7.6.2 (i), 7.6.2(ii) and 7.6.2(iii), arbitration
determines that VOTORANTIM has not completed the Qualified Expenditures which
completion is claimed by VOTORANTIM, this company will be entitled to deliver to
MINERA SOLITARIO, within a maximum period of thirty (30) calendar days following
the date in which the decision is notified, an amount equal to such difference;
in which case the Qualified Expenditures which investment was claimed by
VOTORANTIM, shall be understood to have been completed. If VOTORANTIM does not
make the corresponding payment within the aforesaid thirty (30) days term, it
shall be deemed that VOTORANTIM did not complete the Qualified

21

<PAGE>

Expenditures that it had included in the reports subject matter of revision by
the consultant firm referred to in section 7.6.4 above.

7.7     It shall be understood that VOTORANTIM has complied with the conditions
set out in sections 7.3 and 7.4, upon the alternative occurrence of any of the
following:

(i)     MINERA SOLITARIO accepts in writing that VOTORANTIM has satisfied them;

(ii)     When through the decision of the consultant firm mentioned in section
7.6.4, it is determined that VOTORANTIM has completed the Qualified Expenditures
referred to in section 7.3.; or,

(iii)     If applicable, when VOTORANTIM has paid to MINERA SOLITARIO any
deficiency sums for the Qualified Expenditures mentioned in section 7.3 (as
defined in section 7.5.5) and 7.4.

:          CLAUSE INTENTIONALLY LEFT IN BLANK by the parties

Nine

:          Operations of CHAMBARA

9.1     Considering that it is the Parties' intention that CHAMBARA refrain from
any activity that could result in any kind of liability for this company or that
could affect in any way its legal, economic, and/or financial situation during
the term of the Mining Assignment Agreement, MINERA SOLITARIO expressly commits
to cause CHAMBARA to completely suspend its operations and activities during the
term of the Mining Assignment Agreement and any extensions of the latter.

Accordingly and during the above mentioned term, MINERA SOLITARIO will only
cause CHAMBARA to comply with the legal obligations to which the latter might be
subject to (such as the timely filing of tax returns) and to the compliance of
the stipulations contained herein which might result applicable to CHAMBARA. In
addition and during the same term, MINERA SOLITARIO will refrain from, in any
way, encumbering or contracting over CHAMBARA's shares or somehow affecting
them.

In this sense, Parties hereby expressly agree that only as from the date in
which the Mining Assignment Agreement is terminated, CHAMBARA will assume
control and responsibility over the Properties and the activities undertaken in
them. Before that date, VOTORANTIM will continue being in charge and responsible
for the activities to be carried in the Properties and the decisions pertaining
the same.

9.2     As from the date in which VOTORANTIM has earned-in a 70% interest in
CHAMBARA as a result of MINERA SOLITARIO performing the FIRST and SECOND

conducting further exploration activities;

the preparation of any additional Feasibility Studies or similar studies;

funding the construction or development of a mine in the Properties;

beginning Commercial Production;

continuing operations and; in general, for

developing CHAMBARA's activities;

shall be borne in a pro rata basis by the Shareholders in accordance with their
shareholding interest in CHAMBARA. For these effects, the stipulations contained
in clause twelve with regard to the approval and execution of Programs and
Budgets will apply.

9.3     Upon the termination of the Mining Assignment Agreement referred to in
clause six and as long as VOTORANTIM keeps, at least, a 50% shareholding
interest in CHAMBARA, it shall be the Operator of the Properties. The Operator
shall supervise and direct all relevant mining activities developed therein. For
such purpose, the Operator shall nominate and appoint the General Manager of
CHAMBARA. The other Party shall vote in accordance to this clause.

22

<PAGE>

However, if VOTORANTIM reduces its shareholding interest in CHAMBARA to less
than 50%, the Party that holds a majority interest may, at its option,
immediately becomes the Operator.

9.4

     The decisions and resolutions of CHAMBARA's Shareholders' Meeting or
Directors' Meetings shall be adopted in accordance to the quorum and majority
provisions established in the Peruvian General Corporate Act except as provided
for in section 13.1.

Notwithstanding the foregoing, the approval of the amendment of CHAMBARA's
bylaws related to capital increases for the purposes of financing referred in
section 9.4.1, and of the encumbrances mentioned in section 9.4.11, will require
a quorum of 66% in first call or 60% in second call, and the favorable vote of
the absolute majority of the shares issued by CHAMBARA, at a Shareholders'
Meeting; while the issues enumerated in sections 9.4.2, 9.4.3, and 9.4.5 will
require a quorum and favorable vote of at least 90% of the shares issued by
CHAMBARA, at a Shareholders Meeting; while the approval of the issues enumerated
in sections 9.4.1, 9.4.4, 9.4.6, 9.4.7, 9.4.8, 9.4.9 and 9.4.10 will require a
quorum and favorable vote of at least 81% of the shares issued by CHAMBARA, at a
Shareholders Meeting.

9.4.1     Amendments to the bylaws of CHAMBARA, excluding any amendment related
to any increase of CHAMBARA's capital stock to be implemented for the financing
of any of the phases of the mining activities to be carried out in the
Properties during their mine life, in which case the approval of such amendment
of CHAMBARA's bylaws shall be subject to and regulated by the provisions of the
Peruvian General Companies Act, without being subject to any supermajority or
similar provision whatsoever;

9.4.2     Changes in the means of calculation of the shareholding interest of
the Parties in CHAMBARA (dilution provisions);

9.4.3     The amendment or alteration in the rights or conditions attaching to
the shares issued by CHAMBARA;

9.4.4     The approval of CHAMBARA's policy for the allocation of dividends
distribution;

9.4.5     An amendment to the method for appointing CHAMBARA's Directors, which
is hereby agreed to be equivalent to the provisions established for those
effects in the Peruvian General Corporate Act, that foresees the representation
of minority Shareholders in the Board of Directors, should those Shareholders
hold enough shares to be represented subject to the provisions of section 13.1;

9.4.6     The dissolution, fusion, reorganization and liquidation of CHAMBARA;

9.4.7     Except as permitted in this Agreement (e.g. the allocation of minerals

or arrangement with any of its Shareholders or with Affiliates or Subsidiaries
of the latter; or,

9.4.8     Engaging in businesses that are not part of the ordinary course of

or encumbrance of the Property.

Ten

:          Right of first offer

10.1    In the event that a Party wishes to transfer or assign in any way its
shares in CHAMBARA (the "Selling Party"), the Selling Party shall communicate
the terms and conditions under which it will be willing to formalize such
transfer or assignment to the other Party (the "Non-Selling Party") and grant
them a "right of first offer" for a period of forty five (45) days to decide
whether they accept to enter into the transfer or assignment under the terms
proposed by the Selling Party.

If the Non-Selling Party decides not to enter into the proposed transfer or
assignment, the Selling Party shall have a ninety (90) days term to formalize
such transfer or assignment in favor of third parties on no less favorable terms
than those offered to the Non-Selling Party. If the transfer or assignment is
not formalized within such term, the Selling Party will be required to comply
again with the procedure set forth in this section.

        The "right of first offer" stipulated in this section shall not be
applicable to any transfer or assignment made to an Affiliate or Subsidiary of
the Parties.

10.2   The creation of usufructs, pledges (garantías mobiliarias) or any other
type of lien or encumbrance over the shares issued by CHAMBARA, or over any
right pertaining to those shares, or the issuance of an irrevocable mandate in
favor of another party for it to exercise any of the rights described in this
paragraph, will be governed by the provisions contained in this clause ten
related to the transfer of shares.

Without prejudice of the above, the Parties are only authorized to encumber its
shares in CHAMBARA for purposes of obtaining the financing for the development
and construction or the operating costs of a mine by CHAMBARA, as provided
herein.

10.3   The restrictions to the transfer of shares stipulated in this clause,
will not apply to transfer of shares made by the Parties to Affiliates or
Subsidiaries. However, before any such transfer is formalized, the Party that
intends to perform the same shall obtain from the Affiliate or Subsidiary to
which the shares will be transferred, a commitment to unconditionally adhere in
writing to the rights and obligations stipulated in this Agreement, thus
undertaking the contractual position of the Party that transferred its shares in
CHAMBARA, in the same terms as the latter did, without any limitation.

Since it is the Parties' intention to keep CHAMBARA's shares under their control
or the control of their successors, should that be the case, the Parties hereby
agree that during the validity of this Agreement the Affiliate or Subsidiary
company acquiring the shares will be required to maintain such condition with
respect to the Party that transferred the shares in its favor.

10.4   The Parties hereby declare that the restrictions stipulated in this
clause for the transfer of CHAMBARA's shares, will be included in CHAMBARA's
bylaws. They also declare that the acquisition of CHAMBARA's shares by its
Shareholders in accordance to the right of first offer, will be exercised in a
pro rata basis with the participation of each Shareholder in CHAMBARA's capital
stock and in accordance to the number of shares with respect of which any of
such rights are being exercised.

10.5   The Parties hereby agree that as from the moment in which the transfer of
CHAMBARA's shares is formalized, the transferring Party will be exempted from
any new obligation that might accrue and be enforceable in accordance to the
stipulations contained in this Agreement and that could have resulted from its
condition of Shareholder of CHAMBARA.

Eleven

:          Dilution

11.1   If any of the Parties fail to comply with contributing the pro rata
portion of the costs and expenses included in the Programs and Budgets approved
by CHAMBARA's Board of Directors, the shareholding in CHAMBARA's capital of the
Party that fails to comply shall be diluted by the application of the following
formula to be used to adjust the new shareholding interests:

PA =     CA X 100
                 CT

Where:

-       PA is the new shareholding interest of one of the Parties in CHAMBARA's
capital stock.

-       CA is the total contribution in Initial Capital plus other subsequent
contributions which that Party has made or has deemed to have been made in the
Properties.

-       CT is the total contribution made or deemed to have been made by both
Parties in the Properties.

As soon as practicable after the necessary information is available at the end
of each period covered by an adopted Program and Budget, a recalculation of each
Party's shareholding interest in CHAMBARA shall be made in accordance with the
preceding formula to adjust, as necessary, the recalculations made at the
beginning of such period to reflect actual contributions made by the Parties'
during the period. The adjustment of the Parties' shareholding interest shall be
effected as soon as practicable (but at least with the periodicity stipulated in
section 12.5) using the most tax efficient method taking into account the
interests of all of the Parties and CHAMBARA, provided, however, that if there
is any unnecessary payment or contingency of any kind that result for CHAMBARA
or any Party as a consequence of the dilution and subsequent adjustment of
CHAMBARA's shareholding interest, the diluted Party shall assume those payments
and contingencies. Except as otherwise provided in this Agreement, a diluting
Party shall retain all of its rights and obligations under this Agreement,
including the right to participate in future Programs and Budgets at its
recalculated shareholding interest.

Likewise, the Parties undertake to vote affirmatively in the CHAMBARA's
Shareholders' Meeting to be held in order to capitalize such sums of money as
may be required to evidence the shareholding interest resulting from the
application of the dilution formula, as well as to carry out any other act
necessary to achieve such goal.

11.3    In the event any of the Parties reduces its shareholding participation
in CHAMBARA's capital stock to less than 10%, such participation will be
substituted by a two percent (2%) net smelter royalty (NSR) to be determined and
paid in accordance to Annex D herein.

Twelve

:          Programs and Budgets

12.1   Once CHAMBARA has assumed control and responsibility over the Properties
as stipulated in section 9.1, the General Manager of CHAMBARA shall submit for
the consideration of CHAMBARA's Board of Directors the proposal of the Programs
and Budgets to be implemented. Except in the case of the Program and Budget for
the construction of a mine, subsequent Programs and Budgets should be for
maximum terms of twelve (12) months. The above mentioned proposed Programs and
Budgets shall describe in reasonable detail the activities to be developed and
contain a Budget of the exploration, construction or operating costs that are
planned to be incurred therein, as the case may be. The General Manager will be
entitled to include in the Budget an amount equivalent to up to 10% of the
overall amount of the Budget for any possible contingencies.

25

<PAGE>

If within thirty (30) calendar days of presentation of the corresponding
construction Program or subsequent Programs to the Board of Directors and due to
a deadlock, this corporate body is not able to make a decision on the approval
of a given Program and Budget closure plan or any other proposal submitted by
the General Manager that is related to the operations of CHAMBARA, any
Shareholder will be entitled to submit an alternate Program and Budget. If such
alternate Program and Budget is not approved within thirty days the dispute or
disagreement shall be submitted to the binding and final decision of a
consultant firm mutually agreed upon by the Parties.

12.2   CHAMBARA's Board of Directors shall review any proposed Program and
Budget and, if it deems it convenient, will approve it introducing all the
amendments that it might consider convenient as a result of its review.

12.3   The General Manager shall issue Cash Calls to the Parties according to
their shareholding interest in CHAMBARA in accordance with approved Programs and
Budgets.

12.4   The contributions to be made by CHAMBARA's Shareholders in accordance to
this clause, might be effected through capital contributions, loans subject to
subsequent capitalization or in any other way determined by the Board of
Directors.

12.5   At least once every year and at the time the Annual Shareholders' Meeting
is performed, the Shareholders shall agree to increase CHAMBARA's capital stock
in order to adjust their shareholding interests in CHAMBARA in accordance to the
contributions that they had made to CHAMBARA in the Program and Budget under
this Agreement. For these effects, the dilution formula established in section
11.1 and any other applicable stipulations contained herein, shall apply.

12.6   If CHAMBARA's General Manager suspends or does not complete a Program,
the funds that might have been given in advance by the Shareholders for its
execution, shall be applied and used for the performance of the next Program and
Budget to be approved by the Board of Directors. If the Board of Directors does
not approve a Program and Budget within the next calendar year as from the date
in which the term of the previous Program and Budget had elapsed, the above
mentioned funds will be reimbursed to the Shareholders according to their
participation in CHAMBARA, after covering all the maintenance expenses that
CHAMBARA's Board of Directors might approve.

12.7   If any Shareholder decides not to contribute with the Program approved by
the Board of Directors or after doing so fails in providing the corresponding
funds within the term established for those effects, its shareholding interest
will be, for any and all effects, immediately deemed to be adjusted by the
application of the dilution formula set forth in section 11.1, even if the new
shareholding interests of the Parties is not immediately reflected in CHAMBARA's
capital stock through a capital increase.

12.8   Without prejudice of what has been established in this clause, if during
the execution of any Program, at least 80% of the Budget approved by the Board
of Directors is not effectively used, the General Manager shall inform the same
to all the Shareholders within a term not exceed from ten (10) business days as
from the date of completion of the Program.

Any Shareholder that had decided not to contribute to that Program and that as
consequence thereof had been diluted in CHAMBARA, shall have the option to
reimburse to CHAMBARA within the next twenty (20) business days, its
proportional share of the expenses effectively made for covering the Program
which approved Budget was spent in less than 80%. The amount so reimbursed to
CHAMBARA, shall be applied by CHAMBARA for future contributions required from
the Shareholders that did contribute to the Program. On its turn, it would be
deemed that the Shareholder that initially did not

26

<PAGE>

contribute to the completed Program has recovered the shareholding interest that
it had at the time the Program was approved.

12.9   Notwithstanding other stipulations contained in this Agreement, if in any
year with respect of which a Program has not been approved, CHAMBARA's General
Manager is required to incur expenses necessary for maintaining the validity of
the Properties, for covering minimum fixed costs, for complying with legal or
contractual obligations previously undertaken, or for avoiding environmental or
other damages and, in general, for maintaining the facilities of the mine, the
General Manager shall propose a Program and Budget to the Board of Directors.
The Board of Directors shall approve a Program and Budget that would provide
funding to cover such obligations and expenses.

Thirteen

:          Board of Directors of chambara

13.1   Five (5) members shall compose the Board of Directors, except when the
parties' share in CHAMBARA is 50%, in which case four (4) members shall compose
the Board.

As long as MINERA SOLITARIO holds at least a 30% shareholding interest in
CHAMBARA, MINERA SOLITARIO will be entitled to appoint two directors, except
when four (4) members compose the Board, in which case MINERA SOLITARIO will be
entitled to appoint the number of directors permitted by law. For these effects,
classes of shares will be created in CHAMBARA in order to entail the shares to
be held by MINERA SOLITARIO (i.e. class "B" shares), the appointment of the
above mentioned two directors. However, immediately after MINERA SOLITARIO
reduces its shareholding interest to less than 30%, the Parties will attend
CHAMBARA's Shareholders' Meeting to vote in favor of the amendment of CHAMBARA's
bylaws in order to eliminate the existence of classes of shares and, therefore,
to formalize the elimination of MINERA SOLITARIO's right to appoint two (2)
directors.

In addition, it is hereby agreed that during the existence of the right of
MINERA SOLITARIO to appoint two (2) directors in CHAMBARA, for any meeting of
the Board of Directors to be installed, it shall be required the attendance of
at least a number of the directors nominated by VOTORANTIM equivalent to the
number of directors nominated by MINERA SOLITARIO, in order for the respective
Board's meeting to have quorum.

As provided in section 9.4, with the quorum restriction described in the
preceding paragraph (when applicable) and unless otherwise stipulated in this
Agreement, the resolutions of the Board of Directors shall be adopted by simple
majority.

13.2   The Board of Directors may remove at its discretion and effective
immediately CHAMBARA's General Manager in the following cases:

13.2.1     Except as provided in section 14.1, if the Party that appointed the
General Manager no longer has a majority shareholding interest in CHAMBARA.

13.2.2     If the General Manager entered into unauthorized arrangements with
CHAMBARA's creditors, or if the General Manager's insolvency was requested by
the General Manager itself or by any of its creditors in accordance to the
applicable regulations.

13.2.3     If judicial or extrajudicial measures were adopted that significantly
affect the General Manager's assets.

13.2.4     If the General Manager acts with willful misconduct or gross
negligence or if it breaches the obligations or duties applicable to him under
this Agreement, CHAMBARA's bylaws or applicable law.

13.2.5     For non performance at the sole determination of the Board of
Directors.

27

<PAGE>

13.3   If after the removal or resignation of the General Manager, CHAMBARA's
Board of Directors is not able to reach an agreement and pass a resolution
appointing a Shareholder or a third party as the new General Manager, the Board
of Directors shall evaluate the continuity of CHAMBARA's activities or its
potential dissolution and liquidation.

13.4   The Board of Directors shall be called and will carry out its meetings,
in accordance to the stipulations provided for those effects in CHAMBARA's
bylaws and the Peruvian Corporate Act, as applicable.

13.5   Subject to the notice and quorum requirements set forth in CHAMBARA's
bylaws, the Board of Directors may hold meetings by telephone conferences in
lieu of meetings in person. The Board of Directors may also take actions in
writing signed by all members.

13.6   Except as otherwise delegated to the General Manager in clause fourteen
or as otherwise provided in this Agreement, the Board of Directors shall have
exclusive authority to determine all management matters related to this
Agreement.

Fourteen

:          General Manager of CHAMBARA

14.1   With the exception stipulated in the last paragraph of section 14.5, as
long as VOTORANTIM keeps at least a 50% shareholding interest in CHAMBARA, it
shall be the operator of the Properties (the "Operator"). The Operator shall
supervise and direct all relevant mining activities developed therein. For such
purpose, the Operator shall nominate the General Manager of CHAMBARA. In this
sense, the other Party shall vote in CHAMBARA's Shareholders' Meeting and/or
Board of Directors in accordance to this clause; this is, to appoint as General
Manager the Operator's nominee. If VOTORANTIM's shareholding interest should
decrease to less than 50% then the Party with the largest shareholding interest
may, at its option, become the Operator and shall accept its responsibilities
accordingly.

14.2   The General Manager can resign at any time by delivering a notice to the
Chairman of CHAMBARA's Board of Directors, with an anticipation of not less than
thirty (30) calendar days of the effective date of resignation. In this case,
and voting in accordance to the Operator's nomination, the Board of Directors
shall appoint the new General Manager and determine the date in which it will
begin performing its duties.

The General Manager leaving its post (either because it has resigned or because
it has been removed by the Board of Directors) shall provide the new General
Manager with all the information, statements of account, documents and registers
related to its activities in the Properties and CHAMBARA.

14.3   The General Manager shall be responsible for the management and
administration of CHAMBARA and shall conduct all its activities in a correct,
diligent and efficient manner, in accordance with sound standards and practices
applicable in the mining industry, social affairs and environmental protection,
and substantially abiding by the terms and conditions of the concessions,
assignments, licenses, permits, authorizations, contracts and other agreements
pertaining to the Properties and/or CHAMBARA and shall act in the sole interest
of CHAMBARA. The General Manager will work exclusively for CHAMBARA and perform
no other non-CHAMBARA activities for the Shareholders or third parties.
Accordingly, CHAMBARA's General Manager has the following duties:

above, the General Manager shall cause CHAMBARA to maintain proper and complete
records and accounts of all the expenditures and works made with regard to the
Properties, in accordance with accounting principles and standards generally
accepted in the mining industry and based upon an internationally recognized
generally accepted accounting principles and applicable law. Said records and
accounts shall be made available for all of CHAMBARA's Shareholders review and
audit at any time they request them, provided that the costs of any such review
or audit will be assumed entirely by the Shareholder requesting it.

Likewise, CHAMBARA's General Manager shall allow the Shareholders to inspect the
Properties at their own risk and account and abiding by reasonable safety
standards, to the extent deemed reasonable, on the understanding that the
Shareholder conducting such inspection does not interfere excessively with the
activities of CHAMBARA.

(viii)   Make timely and full payment of the Validity Fees of the Properties,
provided that compliance with this obligation shall be made not less than
fifteen (15) calendar days in advance to the date on which under the laws in
force at that time, the payment of Validity Fees shall be made.

(ix)   Supervise the work of the persons designated for trading the mineral
products extracted from the Properties.

(x)     Provide Shareholders' Directors or a designated representative to be
designated by SOLITARIO before VOTORANTIM, access to: authorised agents,
advisors, representatives, counsel, accountants and independent contractors of
CHAMBARA in coordination with the General Manager of CHAMBARA.

14.4   The General Manager will be entitled to hire independent contractors or
professionals to perform the activities required for fulfilling CHAMBARA's
corporate purpose, provided that in all cases the hiring of such contractors and
professionals shall be made in accordance to the prevailing market conditions.
The General Manager shall not act in representation of any of the Shareholders
nor will undertake individual commitments in favor of any one of them, unless
permitted by this Agreement or agreed in writing by the Parties.

29

<PAGE>

14.5   As from the date in which CHAMBARA assumes control and responsibility
over the properties in accordance to section 9.1, CHAMBARA's General Manager
shall prepare and submit to CHAMBARA's Board of Directors, at least on an annual
basis and no later than thirty (30) calendar days before the completion of the
previous Program, the corresponding Programs and Budgets and a provisional Cash
Call schedule for the following period, provided that the Board of Directors
shall review and vote on the proposed Program and Budget within thirty (30)
calendar days of presentation of the same to it. The Board of Directors will
approve what will be finally executed.

CHAMBARA's General Manager will prepare a revised Cash Call schedule based upon
the approved Program and Budget and will execute said Programs and Budgets.
Unless provided otherwise in this document, upon approval of the annual Programs
and Budgets, the Shareholders shall have a thirty (30) calendar day term to
inform CHAMBARA of its decision to contribute or not to the corresponding
Program. The General Manager shall prepare and deliver Cash Calls to the
Shareholders according to the Cash Call schedule or as amended to accommodate an
amended Program and Budget approved by the Board of Directors.

In case any Shareholder could not, or decides not to, contribute with the pro
rata share of the costs and expenses corresponding to said Party according to
the Programs and Budgets approved by the Board of Directors, the dilution
procedure established in section 11.1 will apply. If the diluting Party had
appointed the General Manager, such General Manager will have deemed to have
resigned its post and the other Shareholder will be entitled to appoint the new
General Manager.

14.6   CHAMBARA's General Manager shall not be liable to a Shareholder for any
action or inaction resulting in damages, losses, expenses, penalties or fines,
except if it is due to willful misconduct or gross negligence by the General
Manager. No default by the General Manager of its obligations shall be deemed to
have occurred hereunder, if compliance therewith is rendered impossible owing to
failure by the Shareholder to perform acts required by this Agreement.

According to the above, CHAMBARA will indemnify and hold harmless the General
Manager for any damages that the latter might suffer or liabilities of any
nature that could be imputed against him by third parties, as a result of the
acts performed or not performed in fulfillment of its duties as General Manager,
unless such damages or liabilities have been caused or generated as a
consequence of the willful misconduct or gross negligence of the General
Manager.

:          Financing

15.1   Despite that fact that Parties are obliged to contribute on a pro-rata
basis in their participation in CHAMBARA's capital stock as provided in section
9.2, during the forty eight (48) months following the date upon which VOTORANTIM
earns a 70% interest in CHAMBARA as a consequence of the enforcement of the
FIRST and SECOND OBLIGATIONS TO CAPITALIZE, should that be the case, the Parties
agree that, if so requested in writing by MINERA SOLITARIO within the ten (10)
calendar days following approval by the Board of Directors of an Initial Program
and Budget for construction of a mine, MINERA SOLITARIO's share of the costs and
expenses, in proportion to 30% of CHAMBARA's expenditures necessary to develop
and/or construct a mine in the Properties and begin commercial production, will
be financed by a non-recourse loan funded directly by VOTORANTIM or arranged by
VOTORANTIM through a third party for the benefit of MINERA SOLITARIO, if the
latter accepts the offer to be submitted by VOTORANTIM for providing or
arranging such loan, provided that the offer will foresee the application of
interest rates of LIBOR plus 3.5%.

30

<PAGE>

Upon receipt by MINERA SOLITARIO from VOTORANTIM the terms under which such loan
shall be offered, MINERA SOLITARIO shall have a period of thirty (30) days to
notify VOTORANTIM if the terms are acceptable and the parties to the loan
agreement shall finalize such financing, time being of the essence. If MINERA
SOLITARIO does not accept the terms proposed by VOTORANTIM for providing the
loan, VOTORANTIM will have no further obligation to provide the financing
requested by MINERA SOLITARIO.

For greater clarity, such loan provision shall apply to but not be limited to
the capital investments required for construction of the mine, purchase of
equipment and construction of facilities necessary for mining and processing,
construction of access to the mine and for Programs to optimize or expand such
Programs for the purpose of increasing mine or processing activities or to
comply with requirements of governmental agencies related to environmental or
social Programs related thereto. It is further understood that the sustaining
capital required for ongoing mining activities subsequent to construction of the
mine at full capacity and for the normal course of business is specifically
excluded from this commitment to finance MINERA SOLITARIO undertaken in this
section by VOTORANTIM.

If so required at any time by VOTORANTIM, MINERA SOLITARIO will be obliged to
grant any security deemed necessary or convenient by VOTORANTIM over the shares
that MINERA SOLITARIO might directly or indirectly hold or control in CHAMBARA,
in order to guarantee any and all the obligations that MINERA SOLITARIO will
assume under the loan.

A loan provided by VOTORANTIM for financing will be paid back by MINERA
SOLITARIO from 80% of the dividends or net proceeds from the sale of product
(deducting shipping and other post-production costs) that it is entitled to
receive from commercial production of the Properties, until the loan and accrued
interests are paid for in full. MINERA SOLITARIO shall have the right to
accelerate pay back of any such loan provided by VOTORANTIM and accrued
interests without pre-payment penalty. In the event such proceeds cease, MINERA
SOLITARIO shall not be required to repay such loans until such proceeds again
become available.

If a third party lender so requires as part of the terms of the loan, VOTORANTIM
shall provide a completion guarantee to the lender and shall provide such
guarantee on behalf of SOLITARIO.

15.2   Only and exclusively for the purpose of guaranteeing the loans that might
allow them to make the contributions required for the capital investments in the
Properties, CHAMBARA's Shareholders are entitled to pledge (garantía mobiliaria)
or encumber in any other way their shares in CHAMBARA, as long as the
beneficiary of such securities is a bank or financial entity that had obliged
itself before the other Shareholders to:

(a)     Not foreclose the lien or encumbrance without observing the stipulations
contained herein, to which the security so granted will be subject to;

(b)     The judicial or extrajudicial foreclosure of the security by the bank or
financial entity will be limited to the sale of the entire group of shares
affected with the security to the other Shareholders of CHAMBARA or, if the
latter were not interested in making such acquisition, to the sale of the shares
through a public auction to be performed after notifying all other CHAMBARA's
Shareholders with an anticipation of thirty (30) calendar days, as long as, as
condition for the sale, the acquirer obliges in advance, in a manner that is
satisfactory to the legal advisor to the Party that had appointed CHAMBARA's
General Manager, to:

31

<PAGE>

(i)     undertake all the obligations related to this Agreement that
corresponded to the Shareholders which shares are transferred in an auction;
and,

(ii)     be bound by the terms and conditions of this Agreement.

15.3   In the event CHAMBARA's Board of Directors approved the financing of the
construction of a mine under the concept of "project finance" with banks or
other financial entities, each shareholder will pledge (garantía mobiliaria) its
shares in CHAMBARA or encumber them in the way required for satisfying the terms
and conditions of the financing. The granting of a pledge over CHAMBARA's shares
for formalizing a "project finance", shall have preference over any other kind
of security that the shareholders might grant in accordance to section 15.2
above.

:          Construction of a Mine and Operation

16.1   Subject to the provisions contained in clause eight, the General Manager
of CHAMBARA shall implement the construction of the mine in accordance to the
Feasibility Study and to the Programs and Budgets approved by the Board of
Directors. During the construction phase, the Board of Directors may introduce
and approve any amendments that it deems necessary to complete the Programs and
Budgets previously approved.

16.2   The General Manager of CHAMBARA shall set the schedule in which the
construction of the mine shall be completed and the date as from which the
operations of the mine shall be conducted in accordance to the approved Program
and Budget of operations.

16.3   Before the date of completion of the construction of the mine, the
General Manager shall propose to the Board of Directors the first annual Program
and Budget of operations that shall provide for the operation of the mine until
the end of the calendar year during which construction will have been completed.
Subsequently and before November 15 of each subsequent year, the General Manager
shall propose the annual Program and Budget of operations for the following
calendar year. Each proposed annual Program and Budget of operations shall
contemplate the following:

(a)     The details of the exploration, development and production activities
which are expected to be performed during the period;

(b)     A detailed estimate of the exploration, development, production and
sales and general administrative (SG&A) costs plus an additional and reasonable
amount for contingencies;

(c)     An estimate of the quantity and quality of the ore that will be mined,
and of the ore concentrates to be produced and an accounting of the reserves and
resources contained on the Property in accordance with internationally
recognized standards compliant with National Instrument 43-101 or JORC;

(d)     An estimate of the sustaining capital and new capital investment needed
to maintain or improve the production and operational standards;

(e)     Any other aspects that might be reasonably necessary to include in order
to explain the results that are expected to be obtained with the execution of
the annual plan of operations.

16.4   The Board of Directors shall approve the annual Program and Budget with
the amendments that it deems convenient, before December 1 of the year previous
to the one with respect of which the plan has been approved.

16.5   Notwithstanding any other stipulation contained in this Agreement, if in
a given year a Program and Budget is not approved and CHAMBARA is required to
incur expenses necessary for maintaining the validity of the Properties, for
covering fixed costs or for complying with legal or contractual obligations
previously undertaken, or for avoiding environmental or other damages and, in
general for maintaining the facilities of the mine, the Board of Directors shall
approve a Program and Budget that should sufficiently cover such obligations and
expenses until the next Program and Budget is approved or until

32

CHAMBARA's Shareholders' Meeting adopt the decisions necessary for CHAMBARA to
continue fulfilling its corporate purpose.

Seventeen

:          Suspension and Termination of Operations

17.1   At any time CHAMBARA's General Manager may recommend to the Board of
Directors to suspend operations. Such recommendation shall be presented along
with the plan proposed for maintaining the infrastructure and facilities of the
mine and the assets of CHAMBARA during the term in which the operations will be
suspended. If the Board of Directors approves the recommendation in accordance
with the provisions of section 9.4, the operations will be suspended and the
Shareholders obliged to make the contributions necessary for financing the
maintenance plan.

17.2   CHAMBARA's General Manager may at any time recommend to the Board of
Directors the definite termination of operations. The recommendation shall be
presented along with a plan and budget for implementing the closure of the mine,
without prejudice of the closure plan that CHAMBARA had filed in compliance with
Law 28090 or any other norm that complements or substitutes the latter,
including reasonable detail of the activities to be developed during the closure
and reclamation of the area in accordance to applicable regulations.

17.3   The Board of Directors may approve, introducing all the amendments that
it might deem convenient, the definite conclusion of the operations and the
closure plan proposed by the General Manager. If the Board of Directors approves
the closure plan in accordance with section 9.4, the General Manager shall:

(a)     Implement the mine closure plan. The Shareholders will be obliged to pay
the costs required for implementing such plan, in a pro rata basis to their
shareholding interests in CHAMBARA;

(b)     Withdraw, sell or dispose of the assets that might be disposed in a
manner most advantageous for CHAMBARA, as well as those other assets for which
disposal is required in order to comply with environmental and other applicable
regulations;

(c)     Sell, abandon or dispose the Properties, as it may correspond and in
accordance with clause 19.

When adopting any decision related to the acts referred to in paragraphs (b) and
(c) above, any applicable provisions in the applicable law or CHAMBARA's bylaws
with respect to the matters that should be decided by CHAMBARA's Shareholders'
Meetings bylaws, shall be observed.

17.4   If the Board of Directors does not approve the closure plan, the General
Manager shall continue executing the maintenance plan approved according to the
provisions contained in this clause.

Eighteen

:          Allocation of Minerals

18.1     The sale of any mineral products by CHAMBARA shall be done under
competitive terms on the open market. Notwithstanding the above, the
Shareholders will individually have the right to request CHAMBARA to directly
sell to them, under a long term contract, a portion or all the minerals produced
by the mine that is equivalent to their shareholding interest in CHAMBARA.

For those effects, it is hereby agreed that any long term contract for the sale
of minerals by CHAMBARA, shall conform to the following guidelines:

CHAMBARA and any potential buyer of concentrates (the "Buyer") shall negotiate
in good faith and with the intent to reach agreement, for which effects they
will be consistent with the then prevailing international market terms
applicable for the delivery of mineral concentrates with similar product
characteristics for respective contractual periods, between mines and custom
smelters on an arm's length basis.

33

<PAGE>

International market terms for concentrate (benchmark) shall mean transactions
between major mines and custom smelters located in Japan, Korea, Oceania, North
America, South America and Western Europe. After the first calendar year during
which initial shipments from the mine are made, all terms for long term
contracts shall conform to the calendar year (the "Year") and shall be
negotiated for shipments during such Year.

(i)     If terms are not agreed upon between CHAMBARA and the Buyer by the
commencement of Commercial Production, then deliveries shall start at a normal
rate and shall be provisionally accounted at the economic terms published by CRU
(Commodities Research Unit) and Brook Hunt as the then prevailing "benchmark"
for zinc for the preceding or current calendar year, as the case may be, subject
to final adjustment as soon as the final terms for the contractual Year of
reference are known or as otherwise described earlier in this clause.

(ii)    If terms are not agreed upon between CHAMBARA and the Buyer by the end
of the customary annual negotiating period under a long term contract, then
deliveries shall continue at a normal rate and shall be provisionally accounted
at the economic terms applicable to the preceding Year, subject to final
adjustment as soon as the final terms for the contractual Year of reference are
known.

(iii)   Should CHAMBARA and the Buyer not have reached agreement for annual
terms under a long term contract by the time shipments commence, and if CHAMBARA
has agreed to terms with any of CHAMBARA's other customers, then those terms
shall be used provisionally until terms are agreed between CHAMBARA and the
Buyer.

(iv)   Should the negotiations to finalize the terms in any given Year be
delayed beyond March 31 of any Year, either Shareholder may request a further
revision of the provisional terms so that they more accurately reflect the then
prevailing benchmark discussions.

(v)     Should a benchmark agreement not be reached between the major mines and
smelters referred to above, CHAMBARA and the Buyer shall, nevertheless, make
their best efforts to reach an agreement on terms reflecting the best possible
information available on market conditions.

(vi)    Should CHAMBARA and the Buyer be unable to reach agreement, then the
matter may be referred to arbitration as per clause 30.

18.2   Before the minerals are sold or delivered, the General Manager will cause
the weighing or calculation of the volume of the minerals, by taking samples and
making assays and tests in accordance to standard mining and metallurgical
practices. The General Manager shall keep a record of the weights obtained and
calculations made, as the case may be, and of the results of the assays and
tests performed. The Shareholders shall individually have the right to take
their own samples and make their own calculations relating to weights in order
to confirm the grade and quantity of product subject of their interest.

18.3   The Shareholders are entitled to dispose or in any way enter into
transactions with respect to the minerals produced by the mine to which they
have allocation rights as agreed to in this clause, as from the date in which
such minerals are put at their disposal as a result of the Shareholders having
exercised the right granted to them under section 18.1. Title over the minerals
will be acquired by Shareholders as from the date established for those effects
in the corresponding purchase or supply agreement executed with CHAMBARA.

Nineteen

:          Abandonment of Properties

19.1   As from the date of signature of this Agreement and during the term of
the Mining Assignment Agreement, CHAMBARA will be expressly impeded to abandon
or cause in any way the abandonment or extinction of any of the mining
properties making up the Property, unless the same is first specifically

34

<PAGE>

authorized by VOTORANTIM in writing, which authorization may be discretionally
withheld by VOTORANTIM. For purposes of this clause, the definition of "mining
properties" comprises any and all surface rights, water rights, licenses,
permits, authorizations or any other kind right or authorization granted,
obtained or acquired within the Area of Interest or held by CHAMBARA, with no
limitation.

If during the term prior to the FIRST OBLIGATION TO CAPITALIZE, VOTORANTIM
decides to abandon or release any of the mining rights making up the Properties,
it shall notify of its decision to SOLITARIO RESOURCES with an anticipation of
thirty (30) calendar days, provided that then such mining right shall be
excluded from the scope of this instrument. Likewise, the Mining Assignment
Agreement provided for in the clause six, shall be automatically terminated with
respect to the abandoned or released Property. The Parties hereby expressly
agree that upon receipt of VOTORANTIM's notice and all information that has been
collected by VOTORANTIM in relation to the property, SOLITARIO RESOURCES shall
have a ten (10) calendar days term to notify in writing VOTORANTIM that has
adopted one of the following decisions:

(i)     That the respective Property be formally abandoned/renounced by
CHAMBARA, in which case SOLITARIO RESOURCES and SOLITARIO PERU shall cause
CHAMBARA to file before the Peruvian mining authorities all the documents
necessary to formalize such abandonment/renouncement within the following
fifteen (15) calendar days;

(ii)    That SOLITARIO PERU or another Peruvian company or individual will
acquire the Property from CHAMBARA, in which case SOLITARIO RESOURCES and
SOLITARIO PERU shall cause CHAMBARA to formalize the acquisition within the next
fifteen (15) calendar days, through the execution of a donation agreement,
provided that no cost whatsoever should be caused to CHAMBARA as a consequence
of the above (any eventual cost so incurred shall be undertaken by SOLITARIO
RESOURCES).

If no answer is provided in writing by SOLITARIO RESOURCES to VOTORANTIM within
the ten (10) calendar days term referred to in above, it shall be deemed as if
SOLITARIO RESOURCES had elected alternative (i) above.

Regardless of which alternative is (or is deemed to have been) elected by
SOLITARIO RESOURCES, VOTORANTIM shall return to CHAMBARA the possession of the
abandoned Property and shall provide to such company any and all information
and/or documents that may have been prepared and/or obtained as consequence of
the activities performed in such Property.

For the purposes of this section, it shall be understood that VOTORANTIM has
abandoned the Property as from the time in which it evidences, at the
satisfaction of MINERA SOLITARIO, that the Property is in force, free from any
charge or lien, and with all taxes, rights, Validity Fees duly paid, without
having deferred or omitted payment of the Validity Fees or applicable penalties
even in one year.

VOTORANTIM shall have the right to remove from the abandoned Property,
facilities, equipment, machinery, tools, appliances and any other property of
its own or belonging to contractors, within three (3) months as from the time
when such Property was abandoned, otherwise, they shall remain in favor of
MINERA SOLITARIO, without any cost for the latter.

19.2   If after CHAMBARA has assumed control and responsibility over the
Properties in accordance to section 9.1, CHAMBARA's General Manager intends to
abandon any of the mining rights making up the Property, it must give written
notice on its decision to the Party that had not nominated its appointment as
General Manager, and such other Party may elect that said Property be
transferred to it.

35

<PAGE>

Under the assumption that the Party that has not nominated CHAMBARA's General
Manager elects not to acquire the Property or does not reply to the General
Manager on the decision within thirty (30) calendar days following the receipt
of the notice delivered by the General Manager according to the foregoing
paragraph, it is expressly provided that CHAMBARA may abandon said Property,
which will be, as from that time, beyond the scope of this Agreement.

Should the non-operating Party elect that the Property be transferred to such
Party, then, the General Manager must make sure that said Property is in full
force and effect and free from any charge or lien, and that all taxes, rights,
fees that may result applicable are paid during the following six (6) months,
without having deferred or omitted payment of the Validity Fees or applicable
penalties even in one year.

For the purposes of this section 19.2, it shall be understood that CHAMBARA has
abandoned the Property as from the time when it evidences, at the satisfaction
of the non-operating Party, that the Property is in force, free from any charge
or lien and with all taxes and fees duly paid.

19.3   It is expressly agreed that the definition of Property contained in
section 1.15 shall be amended as to not to include the mining rights involved in
the Property subject to abandonment or transfer referred to in this clause.

19.4   The Parties expressly agree that neither of them may establish nor
acquire, whether directly or indirectly or otherwise, mining rights or interests
in the areas that would have been made subject to abandonment in accordance with
this clause, for a twelve (12) month term as from the date in which the
abandonment was effective. The definition of "mining properties", "mining
rights" or "Property" used in this clause comprise any surface right, water
right, license, permit, authorization or any other kind of right or
authorization that may have any relationship, whether directly or indirectly, to
the Properties or the areas mentioned above.

19.5   The abandonment of Properties under this clause does not release the
Parties from their Continuing Obligations in respect of the abandoned
Properties.

Twenty

:          Acquisition of mining properties

20.1   The Parties expressly agree that during the validity of this Agreement,
and as long as VOTORANTIM is Operator, VOTORANTIM may, at it sole discretion and
at any time it deems it convenient, file, establish or acquire in any manner
whatsoever any mining property or interest within the Area of Interest, provided
that such filing, establishment or acquisition shall be performed under the name
of CHAMBARA. The expenses incurred by VOTORANTIM for making the aforesaid
filing, establishment or acquisition, will be considered Qualified Expenditures
for the purposes of this Agreement.

On its turn, it is hereby agreed that during the validity of this Agreement,
MINERA SOLITARIO may not file, establish or acquire in any manner whatsoever any
mining property or interest within the Area of Interest, unless prior written
consent is given by VOTORANTIM, in which case the corresponding property will be
acquired and/or filed in the name of CHAMBARA. This restriction is applicable to
any surface right, water right, license, permit, authorization or any other that
may have any direct or indirect relationship with the Area of Interest and/or
the Properties.

For purposes of this clause, the definition of "mining properties" comprises any
and all surface rights, water rights, licenses, permits, authorizations or any
other kind right or authorization granted, obtained or acquired within the Area
of Interest, with no limitation.

If MINERA SOLITARIO became the Operator in substitution of VOTORANTIM, the
provisions established in the preceding paragraphs of this section referred

36

<PAGE>

to VOTORANTIM will apply, as from that time, to MINERA SOLITARIO, and vice
versa.

20.2   After CHAMBARA has assumed control and responsibility over the Properties
in accordance to section 9.1, CHAMBARA's Board of Directors may decide on the
convenience of acquiring a mining property within the Area of Interest. Upon
adopting such decision, CHAMBARA's General Manager shall make its best efforts
to acquire the right, title or interest that may correspond to the said mining
claim (the "New Property"), which will be subject to the actions adopted by the
Board of Directors.

Once the General Manager acquires the New Property for CHAMBARA, the same shall
be understood as a Property and shall be subject to the terms and conditions of
this Agreement.

20.3   It is hereby established that the provisions contained in this clause are
not applicable to any mining properties that the Parties or any Affiliate or
Subsidiary of the latter, might under any title have within the Area of Interest
prior to the execution of this Agreement or the Area of Interest as so amended
as of the date of the amendment.

Twenty one

:          Indemnity

21.1   VOTORANTIM shall indemnify and save harmless MINERA SOLITARIO as to any
liability for or on the account of any injury or loss to persons or property
which results from any act or omission directly attributable to VOTORANTIM
respecting the Properties.

On its turn, MINERA SOLITARIO shall indemnify and save harmless VOTORANTIM as to
any liability for or on the account of any injury or loss to persons or property
which results from any act or omission directly attributable to MINERA SOLITARIO
respecting the Properties.

21.2   CHAMBARA shall indemnify and save harmless its officers, General Manager
and Directors as to any liability for or on the account of any injury or loss to
persons or property which results from any act or omission attributable to
CHAMBARA's activities, except for gross negligence or wilful misconduct of such
officers, General Manager or Directors.

Twenty two

:          Termination

This Agreement shall be terminated in the following cases:

22.1    Pursuant to the provisions established in this section, VOTORANTIM shall
at any time prior or after earning a shareholding interest in CHAMBARA, have the
right to unilaterally and without cause and without any further investment or
payment obligations to MINERA SOLITARIO accrued or not (except for the firm
obligation to complete the investment indicated in section 7.3.1 or paying any
balance directly to MINERA SOLITARIO), terminate this Agreement through the
delivery of notarized notice to MINERA SOLITARIO, provided that such termination
shall be effective thirty (30) calendar days after receipt of said notice by
MINERA SOLITARIO. Such unilateral withdrawal shall, however, not release
VOTORANTIM from any Continuing Obligations in relation to the Properties or to
this Agreement.

Upon exercising this unilateral termination, VOTORANTIM shall not recover the
amounts invested, spent and/or paid until the effective date of termination in
connection with this Agreement and/or the compliance with its obligations
hereunder, provided that VOTORANTIM shall have paid all the Validity Fees of the
Properties in accordance to section 6.7.3.

In addition, the following provisions will apply in case of termination of this
Agreement:

(i)     Should termination occur prior to the performance of the FIRST
OBLIGATION TO CAPITALIZE and after the Date of Initiation of the Mining
Assignment, VOTORANTIM shall be irrevocably obligated to

37

<PAGE>

return to CHAMBARA the possession of the Properties in force and free from any
charge, encumbrance or lien, without limitation.

VOTORANTIM shall have the right to remove from the abandoned Property, the
facilities, equipment, machinery, tools, appliances and any other property of
its own or belonging to contractors, within three (3) months as from the time
when such Property was abandoned, otherwise, they shall remain in favor of
CHAMBARA, without any cost for the latter.

(ii)     Should termination occur prior to the performance of the FIRST
OBLIGATION TO CAPITALIZE and after the Effective Date, VOTORANTIM will deliver
to MINERA SOLITARIO copy of any and all the information, results and/or
documents including all interpretive reports containing conclusions and
recommendations that VOTORANTIM might have obtained, prepared or gathered in
connection with the Properties.

(iii)     If termination occurs at any time after MINERA SOLITARIO performs the
FIRST OBLIGATION TO CAPITALIZE, only the provisions contained herein related to
CHAMBARA's operation and the relationship between the Parties as Shareholders
and related to the activities to be carried out by CHAMBARA in the Properties,
and CHAMBARA's operation, shall remain in force and enforceable except as
provided for in section 22.5.

(iv)     In any case of termination of this Agreement, VOTORANTIM will maintain
the shareholding interest that it had already earned-in in CHAMBARA until the
effective date of termination.

22.2   In addition to any specific cause of default stipulated in this document,
any of the Parties may terminate this Agreement due to the material default of
the other Party of complying with any of its obligations hereunder.

If a Party believes that there is default on the part of the other Party the
non-defaulting Party shall require the other Party, through the delivery of a
notarized notice, to remedy such default within a maximum thirty (30) days term.
If the Party alleged to have defaulted fails to remedy such default or to
respond to the allegation of default within such term then the defaulting Party
shall be deemed to have defaulted and this Agreement shall be automatically
terminated, without need of any further formality or declaration, provided that
the non-defaulting Party will be entitled to demand the defaulting Party payment
of the compensation for the damages that its default might have caused.
Notwithstanding the above mentioned thirty (30) calendar day period for curing
default, if a Party declares in writing that it has not defaulted or has cured
the default and the non-defaulting Party does not agree in writing, then the
non-defaulting Party shall have recourse to invoke the provisions of clause
thirty, arbitration, within a thirty (30) calendar day term following the notice
in which it notified the defaulting Party that it does not agree with it having
not defaulted or with curing its default. If such invocation is not delivered in
writing by the non-defaulting Party within the aforementioned thirty (30)
calendar days term, then it shall be deemed that no default occurred or that
such default has been cured to the satisfaction of the non-defaulting Party.

Notwithstanding the termination of this Agreement, the Parties shall keep, as
