5. CONTRIBUTIONS BY PARTICIPANTS

5.1 PARTICIPANTS' INITIAL CONTRIBUTION

At the time of this  Agreement,  Each  Participant  is  deemed  to have made the
following Initial Contribution to the Joint Venture:

     (a)  Big Rock:  Payment of  $400,000  for the initial  work  program on the
          Property payable as follows:
          a.   $50,000 by May 14, 2011; and
          b.   $350,000 by May 31, 2011.
          c.   $8,500,000 for the cost of putting the Property into  production.
               Payable  according  to cash call by  operator  under an  approved
               budget, estimated to occur over the first two years of operation.

     (b)  These three  payments  shall  together  constitute  100% of Big Rock's
          total required contribution to the Joint Venture; and

     (d)  Siga: Deemed payment of $550,000 (reflecting its initial contribution)
          plus the transfer of title to the Property.  This payment and transfer
          of title  shall  together  constitute  100% of Siga's  total  required
          contribution to the Joint Venture.

5.2 ADDITIONAL CASH CONTRIBUTIONS

Upon  completion  of the  Initial  Contributions,  the  parties  shall  each  be
responsible for 50% of the cash contributions of the Joint Venture.

5.3 PRIORITY OF THIRD PARTY FUNDING

The parties  agree that  wherever  feasible,  priority  will be given to funding
Operations by negotiated joint ventures with third parties,  in particular major
mining  companies,  or  debt,  or  other  appropriate  mechanisms  which  may be
recommended  by  investment  counsel.  All  parties  shall  be  involved  in any
negotiations and shall adopt reasonable positions in good faith.

5.4 THIRD PARTY CONTRACTS

The parties agree that third party  contracts,  whether entered into with majors
or otherwise,  shall not alter,  or be deemed to alter,  the parties' rights and
interests herein as between the parties hereto unless such shall be specifically
provided in such third party  agreement or would be an  unavoidable  implication
thereof and would occur if the event occurred under this Agreement (for example,
a dilution  provision of a third party agreement would operate to dilute a party
to this Agreement but would not extinguish  any carried  interests  provided for
hereunder,  as between the  parties  hereto,  unless the third  party  agreement
specifically  stated that it supersedes  such provision of this  Agreement).  If
additional  rights or property are acquired or made available  under third party
agreements  then  such  rights  and  property  shall  accrue to the  parties  in
accordance with their rights and interests, as they may be from time to time, of
this Agreement  (for example,  if a property is available to the parties under a
third  party  agreement,  then the parties  shall have the right to  participate
therein in accordance with their Participating  Interest herein, as adjusted for
the third party interest under the third party agreement).

6.5 DEFAULT IN MAKING COMMITTED CONTRIBUTIONS

If Big Rock,  having  committed to making a contribution to a Program or Budget,
defaults in making a contribution or cash call or paying an invoiced amount (the
Defaulted Contribution") required by an approved Program and Budget to which Big
Rock had committed to contribute its Proportionate  Share, or some part thereof,
Siga  may  elect,  within  thirty  days of  notice  of the  default,  one of the
following:

     (a)  to  pay  the   Defaulted   Contribution   and  treat   the   Defaulted
          Contribution,  together  with  any  accrued  interest  calculated  and
          compounded on a quarterly basis from advance, as a demand loan bearing
          interest  at a rate of 10% per annum.  The  failure to repay said loan
          upon demand  shall be a default of the deemed loan and Siga may effect
          execution proceedings and take all steps it deems advisable to recover
          the loan and interest,  including auctioning Big Rock's Interest.  Big
          Rock hereby grants to Siga a lien upon and a security  interest in its
          Participating  Interest  in the  Assets  and  the  Property,  and  the
          Products and Net Profit therefrom,  to secure any loan made hereunder,
          including  interest  thereon,  reasonable  legal  fees  and all  other
          reasonable  costs and expenses  incurred in  recovering  the loan with
          interest and in enforcing such lien or security interest, or both; or

     (b)  to have Big Rock's Participating  Interest in the Property (and in the
          Operator) reduced.

Each Participant hereby irrevocably  appoints the other its  attorney-in-fact to
execute,  file and record all instruments necessary to perfect or effectuate the
provisions hereof.

6.6 REASONABLE TIME FOR FINANCING

The parties agree that the payments due in May 2011 shall be made as provided in
section 5.1 A. AND B. An extension of up to 60 days shall be granted to Big Rock
to meet its funding  timelines  for the payments due by cash call in Section 5.1
c.,  if Big Rock has shown a  reasonable  plan to meet the  funding  requirement
within this extended 60 day timeline.

6.7 CONTINUING LIABILITIES UPON ADJUSTMENTS OF PARTICIPATING INTERESTS

Any  reduction of Big Rock's  Participating  Interest in the Joint Venture under
this Section 6 shall not relieve Big Rock of its share of any liability, whether
it accrues before or after such reduction,  arising out of Operations  conducted
prior to such  reduction.  For  purposes of this  Section 6, Big Rock's share of
such  liability  shall be equal to its  Participating  Interest at the time such
liability was incurred. The increased Participating Interest accruing to Siga as
a result of the reduction of Big Rock's Participating  Interest shall be free of

                                       8


royalties,  liens or other  encumbrances,  other than those existing at the time
the Property was  acquired,  those to which both  Participants  have given their
written  consent,  or the Net  Profits  Interest  of Siga.  An  adjustment  to a
Participating  Interest need not be evidenced  during the term of this Agreement
by  the   execution  and  recording  of   appropriate   instruments,   but  each
Participant's  Participating  Interest  shall  be  shown  in  the  books  of the
Operator. However, either Participant, at any time upon the request of the other
Participant,  shall execute and  acknowledge  instruments  necessary to evidence
such adjustment in form sufficient for recording in the  jurisdiction  where the
Property is located.

appointed by Big Rock.  Each  Participant  may appoint one or more alternates to

official  record of the decisions made by the Management  Committee and shall be
binding on the Operator and the  Participants,  except as otherwise  provided in
this Agreement or where inconsistent with this Agreement.  If personnel employed
in operations are required to attend a Management Committee meeting,  reasonable
costs incurred in connection with such attendance shall be a Joint Venture cost.
All other costs shall be paid by the Participants individually.

long as all decisions are immediately confirmed in writing by the Participants.

               Management  Committee,  the  Operator  shall  have  the  right to
               contest in the courts or otherwise, the validity or amount of any

               other steps or  proceedings  as the Operator may deem  reasonably
               necessary to secure a  cancellation,  reduction,  readjustment or
               equalization thereof before the Operator shall be required to pay
               them, but in no event shall the Operator permit or allow title to

               efforts to comply and the  Operator  has,  or has  attempted  to,
               timely cured or disposed of such violation  through  performance,
               or payment of fines and penalties; and

               Assets and the Property.

     (d)  The Operator shall conduct such title examinations and cure such title

          Operator.

     (e)  The  Operator  shall  prosecute  and  defend,  but shall not  initiate
          without  consent  of  the  Management  Committee,  all  litigation  or

          any  determination  by any court or governmental  agency that the work
          performed  by  Operator  does  not  constitute  the  required   annual
          assessment  work  or  occupancy  for the  purposes  of  preserving  or
          maintaining ownership of the claims, provided that the work done is in
          accordance with the adopted Program and Budget and such error does not
          occur due to negligence of reporting of the Operator to the Management
          Committee  or in the  carrying  out of the  Programs or  Budgets.  The
          Operator   shall   timely   record  and  file  with  the   appropriate

          (vii)convert  any  claims  or mill  sites  into one or more  leases or
               other  forms of  mineral  tenure  pursuant  to any law  hereafter
               enacted.

     (k)  The  Operator  shall keep and maintain  all  required  accounting  and
          financial  records  pursuant  to  the  Accounting   Procedure  and  in

                                       13

Proposed Programs and Budgets for the Property shall be prepared by the Operator
for a period of one year, or any shorter period,  or a longer period if approved
by the Management  Committee.  Each adopted Program and Budget for the Property,
regardless  of length,  shall be  reviewed at least once a year or at the end of
the  Program,  whichever  is earlier,  at the annual  meeting of the  Management
Committee. During the period encompassed by any Program and Budget, and at least
three  months  prior to its  expiration,  a proposed  Program and Budget for the
succeeding  period  shall be  prepared  by the  Operator  and  submitted  to the
Participants.

9.3 REVIEW AND APPROVAL OF PROPOSED PROGRAMS AND BUDGETS

Participant shall submit to the Management Committee:

     (a)  notice that the Participant  approves the proposed Program and Budget;
          or

     (b)  proposed modifications of the proposed Program and Budget; or

     (c)  notice that the Participant rejects the proposed Program and Budget.

If a  Participant  fails  to give  any of the  foregoing  responses  within  the
allotted  time the  Operator  shall give the party notice that reply is required
and if  response  is not  forthcoming  within 15 days of delivery of such second
notice the failure shall be deemed to be an approval by the  Participant  of the

                                       16


Operator's proposed Program and Budget and if, upon another 15 days of notice by
the  Operator to such  Participant  that the  Program is  approved  and the said
Participant  must  respond that it will  consider  providing  its  Proportionate
Share,  such Participant does not respond then it will be deemed to have elected
not to participate. If a Participant makes a timely submission to the Management
Committee  pursuant to paragraph  9.3(b) or (c), then the  Management  Committee
shall seek, in a bona fide attempt,  to develop a Program and Budget  acceptable
to the  Participants  otherwise it shall  initiate the  provisions of subsection

By notice to the Management  Committee  within the time provided by section 6.6,
after the final vote adopting a Program and Budget,  a Participant  may elect to
contribute to such Program and Budget in some lesser amount than its  respective
Participating Interest, or not at all, in which cases its Participating Interest
shall be  recalculated  as provided in Section 6. If a  Participant  fails to so
notify the Management Committee, the Participant shall be deemed to have elected
not to contribute  to such Program and Budget in  proportion  to its  respective
Participating  Interest as of the beginning of the period covered by the Program
and Budget.

9.5 DEADLOCK ON PROPOSED PROGRAMS AND BUDGETS

If the Participants,  acting through the Management Committee, fail to approve a
Program and Budget for the Property by the  beginning of the period to which the
proposed Program and Budget applies,  the provisions of Subsections 7.5 and 8.11
shall apply.

9.6 BUDGET OVERRUNS; PROGRAM CHANGES

The Operator shall immediately  notify the Management  Committee of any material
departure from an adopted  Program and Budget for the Property.  If the Operator
exceeds an adopted  Budget by more than 10%,  then the excess over 110%,  unless
directly  caused by an  emergency or  unexpected  expenditure  made  pursuant to
subsection 9.7 or unless otherwise authorized by the Management Committee, shall
be for the sole account of the Operator and such excess shall not be included in
the  calculations  of the  Participating  Interests  for  the  Property.  Budget
overruns of 110% or less shall be borne by the  Participants  in  proportion  to
their respective Participating Interests as of the time the overrun occurs.

9.7 EMERGENCY OR UNEXPECTED EXPENDITURES

In case of emergency or events outside the control of the Operator, the Operator
may take any  reasonable  action it deems  necessary  to protect  life,  limb or
property,  to  protect  the  Assets,  the  Property  or to  comply  with  law or
government  regulation.  The Operator may also make reasonable  expenditures for
unexpected  events  which are beyond  its  reasonable  control  and which do not
result from a breach by it of its standard of care.  The Operator shall promptly
notify the  Participants  of the  emergency or unexpected  expenditure,  and the
Operator  shall be reimbursed  for all resulting  costs by the  Participants  in
proportion to their respective Participating Interests at the time the emergency
or unexpected expenditures are incurred.

Management  Committee shall consider such  Feasibility  Report prepared and may,
subject to the resolution of any outstanding  issues  contemplated in Section 10
herein,  approve the Feasibility Report, with such modifications,  if any, as it
considers  necessary or desirable.  Forthwith  after approval of the Feasibility
Report,  the  Management  Committee  shall cause the Operator to give notice (in
this  Agreement  called  the  "PRODUCTION   RECOMMENDATION")   to  each  of  the
Participants  stating that the Management  Committee recommends that a Mining be
established  and brought into  production  in  conformity  with the  Feasibility
Report as so approved.

11. NOT APPLICABLE

12. CONSTRUCTION OF MINE

12.1 FACILITIES COMPLETION DATE

The Management  Committee  shall cause the Operator to, and the Operator  shall,
proceed with construction of the Mining facilities with all reasonable  dispatch
after a Production Notice has been given. Construction shall be substantially in
accordance  with the Production  Notice,  subject to the right of the Management
Committee to cause such reasonable  variations in construction to be made as the
Management  Committee deems advisable from time to time. The Operator may of its
own  initiative,  and shall  forthwith  upon  request by a  Participant,  call a
Management Committee meeting to consider recommending that the Mining facilities
are  complete  and are  ready to  commence  Operations  for the  production  and
processing  of Product as of a date  determined  by the  Management  Committee (
called  the  "Completion  Date").  Forthwith  upon  the  Completion  Date  being
established, the Operator shall give notice of that date to the parties.

13. OPERATION OF THE MINE

13.1 MINE OPERATING PLAN

Commencing with the Completion Date, all Mining  Operations shall be planned and
conducted  (such plans called the "Operating  Plan") and all estimates,  reports
and statements shall be prepared and made on the basis of an operating year (the
"Operating Year") as determined by the Management Committee.  The Operator shall
submit an Operating Plan for each Operating  Year to the  Participants  not less
than 90 days prior to the Operating Year to which the Operating Plan relates.

Each Operating Plan shall contain the following:

     (a)  a plan of the proposed Mining Operations;

     (b)  a detailed  estimate  of all  construction  costs,  production  costs,
          operating  capital  costs,  administrative  costs and any other costs,
          plus a reasonable allowance for contingencies;

     (c)  an estimate of the quantity and quality of the ore to be mined and the
          concentrates or metal to be produced; and

     (d)  such other facts as may be  necessary  to  reasonably  illustrate  the
          results intended to be achieved by the Operating Plan.

                                       18


Upon request of any  Participant the Operator shall meet with the Participant to
discuss the Operating Plan. The Management  Committee shall adopt each Operating
Plan, with such changes as it deems necessary, not less than 30 days immediately
preceding the  Operating  Year to which the  Operating  Plan relates;  provided,
however,  that the Management  Committee may approve amendments to the Operating
Plan.

14. DISTRIBUTION IN KIND

For the  purposes of this section it should be  understood  that the Project may
not produce a significant amount of free gold at the concentrator. Further it is
assumed at this point that the  concentrate  will likely  require  smelting  and
refining at a third party site.

The Parties specifically agree that they will reach an agreement with respect to
Distribution in Kind until after the evaluation program is completed,  and until
such time the Parties have a pro forma smelting/refining contract in place.

15. SUSPENSION AND TERMINATION OF OPERATIONS

15.1 MINE MAINTENANCE PLAN

The Operator  may, at any time  subsequent to the  Completion  Date, on at least
sixty (60)  days'  notice to all  Participants,  recommend  that the  Management
Committee  approve that Mining  Operations be  suspended,  subject to applicable
mine permitting and closure  regulations.  The Operator's  recommendation  shall
include a plan and budget (called the "Mine  Maintenance  Plan"),  in reasonable
detail,  of the  activities  to be performed to maintain the Assets and Property
during the period of  suspension  and the costs to be incurred.  The  Management
Committee may, at any time subsequent to the Completion Date, cause the Operator
to suspend Mining  Operations in accordance  with the Operator's  recommendation
with such changes to the Mine Maintenance Plan as the Management Committee deems
necessary. The Management Committee may cause Mining Operations to be resumed at
any time.

15.2 MINE CLOSURE PLAN

The Operator or any Participant  may, at any time following a period of at least
ninety (90) days during which Mining  Operations  have been  suspended,  upon at
least thirty (30) days notice to all Participants, recommend that the Management
Committee approve the permanent termination of Mining Operations. The Operator's
recommendation shall include a plan and budget (called the "Mine Closure Plan"),
in reasonable  detail,  of the  activities to be performed to close the mine and
reclaim the Property and the estimated  cost to implement the Mine Closure Plan.
The  Management  Committee  may,  by  approval  of  the  representatives  of all
Participants,  approve the  Operator's  recommendation  with such changes to the
Mine Closure Plan as the Management Committee deems necessary. If the Management
Committee  does not approve the  Operator's  recommendation  the Operator  shall
maintain  Mining  Operations in  accordance  with the Mine  Maintenance  Plan as
approved pursuant to subsection 15.1 herein. Upon Mine Closure,  the title shall
revert back to Siga and/or his assigns.

15.3 IMPLEMENTATION OF MINE CLOSURE PLAN

If the Management Committee approves the Operator's  recommendation as aforesaid
it shall cause the Operator to:

                                       19


     (a)  implement the Mine Closure Plan,  whereupon the Participants  shall be
          committed  to pay, in  proportion  to their  respective  Participating
          Interests, the costs required to implement that Mine Closure Plan;

     (b)  remove,  sell and dispose of such Assets as may  reasonably be removed
          and disposed of  profitably  and such other Assets as the Operator may
          be required to remove pursuant to applicable  environmental and mining
          laws;

     (c)  perform all site  remediation  as required by law,  particularly  with
          respect to mining permits and closure regulations; and

     (d)  sell, abandon or otherwise dispose of the Property.

          The disposal  price for the Assets and the Property  shall be the best
price obtainable,  and the net revenues, if any, from the removal and sale shall
be credited to the Participants in proportion to their respective  Participating
Interests.

16. ACCOUNTS AND SETTLEMENTS

16.1 QUARTERLY STATEMENTS

The  Operator  shall  promptly  submit  to the  Management  Committee  quarterly
statements of account reflecting in reasonable detail the charges and credits to
the Joint Account during the preceding quarter.

16.2 AUDITS AND REPORTS

The  Operator  shall  produce an annual  report and audit  during any  Operating
calendar Year or, if the Management  Committee has adopted an accounting  period

On termination of this Agreement  under sections 17.1 to 17.3, the  Participants
shall remain liable for continuing  obligations hereunder until final settlement
of all  accounts  and for any  liability,  whether  it  accrues  before or after

Exhibit B any Participant  that has a negative  Capital Account balance when the
Joint Venture is terminated for any reason shall contribute to the Assets of the
Joint Venture an amount sufficient to raise such balance to zero. The Assets and
the Property shall first be paid, applied, or distributed in satisfaction of all
liabilities of the Joint Venture to third parties and then to satisfy any debts,
obligations,  or liabilities owed to the Participants.  Before  distributing any
finds or Assets or Property to  Participants,  the Operator shall have the right
to segregate amounts which, in the Operator's reasonable judgment, are necessary
to  discharge  continuing   obligations  or  to  purchase  for  the  account  of
Participants, bonds or other securities for the performance of such obligations.
The  foregoing   shall  not  be  construed  to  include  the  repayment  of  any
Participant's capital contributions or Capital Account balance.  Thereafter, any
remaining  cash and all other  Assets  and  Property  shall be  distributed  (in
undivided  interests unless otherwise agreed) to the Participants,  first in the
ratio  and to the  extent  of  their  respective  Capital  Accounts  and then in
proportion to their respective Participating Interests, subject to any dilution,
reduction,  or termination of such Participating  Interests as may have occurred
pursuant  to the  terms  of this  Agreement.  No  Participant  shall  receive  a
distribution  of any  interest in Products or proceeds  from the sale thereof if
such Participant's  Participating  Interest therein has been terminated pursuant
to this Agreement.

17.6 NON-COMPETITION COVENANTS

Venture  shall not,  directly or  indirectly,  acquire any  interest in property
within a 1.5  kilometers  distance from the  perimeter of the  Property,  for 12
months  after  the  effective  date  of   withdrawal.   If  such  a  withdrawing
Participant,  its  successor or  Affiliate,  acquires  property  subject to this
section 17.6, such party, its successor or Affiliate shall be obligated to offer
to convey to the non-withdrawing  Participant,  at its proportionate acquisition
cost and  geologic and other  expenditures,  a  Proportionate  Share of any such
property or  interest  so  acquired as if such party were still a  Participating
party at the interest  immediately prior to the withdrawal.  Such offer shall be
made in writing and can be accepted by the  non-withdrawing  Participant  at any
time within 45 days after it is received by such non-withdrawing Participant.

17.7 RIGHT TO DATA AFTER TERMINATION

After  termination  of this  Agreement,  each  Participant  shall be entitled to
copies of all  information  of the Joint Venture  before the  effective  date of
termination  not  previously  furnished to it, but a terminating  or withdrawing
Participant shall not be entitled to any such copies after any other termination
or any withdrawal.

17.8 CONTINUING AUTHORITY

authority,  subject to control of the  Management  Committee,  if any, to do all
things  on  behalf  of  the  Participants  which  are  reasonably  necessary  or

                                       21


convenient  to:  (a) wind up  Operations  (either  of the Joint  Venture  or the
Property)  and  (b)  complete  any   transaction  and  satisfy  any  obligation,
unfinished or unsatisfied, at the time of such termination or withdrawal, if the
transaction or obligation  arises out of Operations prior to such termination or
withdrawal.  The Operator shall have the power and authority to grant or receive
extensions  of time or change  the  method of  payment  of an  already  existing
liability  or  obligation,  prosecute  and  defend  actions  on  behalf  of  the
Participants  and the Joint Venture,  mortgage Assets or the Property,  and take
any other  reasonable  action in any  matter  with  respect  to which the former
Participants  continue  to have,  or appear  or are  alleged  to have,  a common
interest or a common liability.

18. ABANDONMENT AND SURRENDER OF THE PROPERTY

18.1 SURRENDER OR ABANDONMENT OF THE PROPERTY

The Management Committee may authorize the Operator to surrender or abandon part
or  all  of the  Property.  If the  Management  Committee  authorizes  any  such
surrender or abandonment  over the objection of a Participant,  the  Participant
that desires to abandon or surrender shall assign to the objecting  Participant,
without  cost  to  the  surrendering   Participant,   all  of  the  surrendering
Participant's  interest in the property to be abandoned or surrendered,  and the
abandoned or surrendered property shall cease to be part of the Property.

18.2 REACQUISITION

of this Section 18, then, unless this Agreement is earlier  terminated,  neither
Participant  nor any successor nor Affiliate  thereof shall acquire any interest
in or a right to  acquire  that part of the  Property  for a period of 12 months
following  the  date of  such  abandonment  or  surrender.  If such  Participant
reacquires any of the Property in violation of this  Subsection  18.2,  then the
other  Participant,  its  successor or Affiliate as the case may be may elect by
notice to the reacquiring  Participant within 45 days after it has actual notice
of such  reacquisition,  to have such part of the  Property  made subject to the
terms of this  Agreement.  In the event such an election is made, the reacquired
part of the Property shall thereafter be treated as the Property hereunder,  and
the costs of reacquisition shall be borne solely by the reacquiring  Participant
and  shall  not be  included  for  purposes  of  calculating  the  Participants'
respective Participating Interests.

          will acquire such offered interest on the terms set out in the notice.
          An offer shall be priced and offered in Canadian dollars. If the offer
          is  not  accepted  by  the  other   Participant,   then  the  offering
          Participant  shall be free to sell such offered  interest for a period
          of 120 days but not at a more favourable price;

     (c)  no  transferee of all or any part of the  Participating  Interest of a
          Participant  shall have the rights of a  Participant  unless and until
          the  transferring  Participant  has provided to the other  Participant
          notice of the Transfer,  and except as provided in paragraphs  19.1(h)
          and 19.l(i), the transferee, as of the effective date of the Transfer,
          has  committed  in writing to be bound by this  Agreement  to the same
          extent as the transferring Participant;

     (d)  no  Transfer   permitted  by  this   Section  19  shall   relieve  the
          transferring  Participant  of  its  share  of any  liability,  whether

          conducted prior to such Transfer;

     (e)  the  transferring  Participant  and the transferee  shall bear all tax
          consequences of the Transfer;

     (f)  in the  event  of a  Transfer  of  less  than  all of a  Participating

          Participant  hereunder.  Upon any foreclosure or other  enforcement of
          rights in the  security  interest the  acquiring  third party shall be

          with respect to this Agreement and the other Participant, and it shall

          to the terms and conditions of this Agreement.
