TSVLP    forty-four and one-half percent (44.5%)

ARTICLE IV
TREATMENT OF CASH FLOW AND EXCLUDED ASSET

4.1 Distributions.

(a)  Prior to the Funding Obligation Date any and
all distributions of Cash Flow to the Members
shall be made according to the Ownership Interest
of the Members on the Effective Date.

(b)  After the Funding Obligation Date but prior
to BACTECH having recouped from all distributions
an aggregate of the Funding Obligation (the
Funding Obligation Account) and at any time there
remains a positive balance in the Funding
Obligation Account, BACTECH shall receive total
distributions of Cash Flow based upon the realized
price of gold by the Company during the operating
period covered by such distributions, as follows:

Averaged Realized Price of Gold  BACTECH share of
                                 Cash Flow
                                 distributions

Account set forth in this Section 4.1(b) is based
on a total estimated expenditure of $16 million by
BACTECH.  In the event that actual expenditures by
BACTECH prior to the Commencement of Commercial
Production are less than $16 million, BACTECH's
incremental share of Cash Flow Distributions shall
be equal to 55% plus A multiplied by B where A is
equal to the applicable share set out above less

expenditures by BACTECH divided by $16 million.

During the period when BACTECH is recovering its
Funding Obligation Account as provided above, the
remaining amount of distributions to TSVLP and
USEC shall be made with TSVLP receiving 44.5/45 of
such distributions and USEC receiving .5/45 of
such distributions.

Funding Obligation Account, one hundred percent
(100%) of positive Cash Flow shall then be
distributed to BACTECH, TSVLP and USEC in
proportion to their respective Ownership
Interests.

(d)  Notwithstanding any provision of this
Agreement to the contrary, Cash Flow (and any
other distributions) otherwise due a Member
receiving an Elected Loan under this Agreement but
distributed instead to BACTECH as provided in
Section 10.6 hereof shall be deemed amounts
distributed to the borrower thereunder for all
purposes, including allocation of income for tax
purposes.

related to its use or ownership of this excluded
asset.

in violation of this Section 5.1 shall be solely

without consulting with, or obligation to, the
other Members or the Company. The doctrines of
corporate opportunity or business opportunity
shall not be applied to the Business nor to any
other activity or operation of any Member outside
the Area of Interest. Except as otherwise provided
in Section 6.5 of the Members' Agreement, no
Member shall have any obligation to the Company or
any other Members with respect to any opportunity
to acquire any property outside the Area of
Interest at any time, or within the Area of

the Manager or such Members.

to have any power as a Member or Manager or any

event shall have only the rights, powers and
privileges of a transferee enumerated in Section

the Member under this Agreement. In no event,
however, shall a personal representative or

any debt, liability or obligation of the Company
whether arising in contract, tort, or otherwise,
except as expressly provided by this Agreement or
the Members' Agreement.

5.11 Indemnities.  The Company may, and shall have
the power to, indemnify and hold harmless any
Member, the Manager or any other person from and
against any and all claims and demands whatsoever
arising from or related to the Business, the
Company, the Assets, Operations or a Member's
membership in the Company.

meeting of the Management Committee. During the
period encompassed by any Program and Budget, and
at least two months prior to its expiration, a
proposed Program and Budget for the succeeding
period shall be prepared by the Manager and
submitted to the Members.

10.4  Review and Adoption of Proposed Programs and
Budgets.  Until the Funding Obligation Date, any
proposed Program or Budget shall be approved
solely by BACTECH.  Following the Funding

(a)  Notice that each Member approves any or all
of the components of the proposed Program and
Budget; or

(b)  Modifications proposed by the Member(s) to
the components of the proposed Program and Budget;
or

(c)  Notice that the Member(s) rejects any or all
of the components of the proposed Program and
Budget.

If any Member fails to give any of the foregoing
responses within the allotted time, the failure
shall be deemed to be a vote by that Member or
Members for adoption of the Manager's proposed
Program and Budget. If any Member makes a timely
submission to the Management Committee pursuant to
Subsections 10.4(a), (b) or (c), then the
Management Committee shall consult regarding the

shall be obligated to agree to any actual change
to a proposed Program and Budget in connection
with such consultations) failing which the
Management Committee shall determine the approved
Program and Budget.

Funding Obligation Date, by notice to the Manager
and BACTECH prior to the approval of a Program and

accrued interest thereon are fully repaid to
BACTECH.

10.7  Deadlock on Proposed Programs and Budgets.
If the Members, acting through the Management
Committee, fail to approve a Program and Budget by
the beginning of the period to which the proposed

continue Operations at levels comparable with the
last adopted Program and Budget but in no event at
levels which do not fully provide for the minimum
holding costs of the Properties.

10.8  Budget Overruns; Program Changes.  The
Manager shall immediately notify the Management
Committee of any material departure from an
adopted Program and Budget.  If the Manager
exceeds the expenditures set forth in an adopted
Budget by more than twenty percent (20%) then the
excess over twenty percent (20%), unless directly
caused by an emergency or unexpected expenditure
made pursuant to Section 10.9 or unless otherwise
authorized by the Management Committee or pursuant
to an Amendment under Section 10.10, shall be
attributed to the sole account of the Manager.
Budget overruns of twenty percent (20%) or less

Members provided funding for the then current
Program and Budget, including the obligation of
BACTECH to provide funding for TSVLP and USEC as

case of emergency, the Manager may take any
reasonable action it deems necessary to protect

beyond its reasonable control and which do not
result from a breach by it of its standard of
care.  The Manager shall promptly notify the
Members of the emergency or unexpected
expenditure, and the Manager shall be reimbursed
for all resulting costs by the Members in the same
manner and with the same consequences and effects
as the Members provided the funding for the then
current Program and Budget.

adopted Program and Budget may be amended only
prospectively by the Manager (the Amendment) upon
30 days notice.  The procedures for review and

with the Company's bank, for the benefit of the
Business Account.

to and claims upon the Manager for discrepancies
disclosed by such audit shall be made not more
than three (3) months after receipt of the audit
report. Failure to make any such exception or
claim within the three (3) month period shall mean

Committee.

the event the Company fails to make any such
required payment, any Member shall have the right
to make such payment and shall thereby become

constitute acceptance by the paying Member of any
liability to such third party for the underlying
obligation.

16.4  Headings.  The subject headings of the
Sections and Subsections of this Agreement and the

this Agreement are included for purposes of
convenience only, and shall not affect the
construction or interpretation of any of its
provisions.  References to hereunder are, unless
otherwise stated, references to this entire
Agreement.

16.5  Waiver.  The failure of any Member to insist
on the strict performance of any provision of this
Agreement or to exercise any right, power or
remedy upon a breach hereof shall not constitute a
waiver of any provision of this Agreement or limit
such Member's right thereafter to enforce any
provision or exercise any right.

16.6  Modification.  No modification of this
Agreement shall be valid unless made in writing
and duly executed by all Members.

16.7  Force Majeure. Except for the obligation to
make payments when due hereunder, the obligations
of a Member shall be suspended to the extent and
for the period that performance is prevented by
any cause, whether foreseeable or unforeseeable,
beyond its reasonable control, including, without
limitation, labor disputes (however arising and
whether or not employee demands are reasonable or
within the power of the Member to grant); acts of
God; Laws, instructions or requests of any
government or governmental entity; judgments or
orders of any court; inability to obtain on
reasonably acceptable terms any public or private
license, permit or other authorization;
curtailment or suspension of activities to remedy
or avoid an actual or alleged, present or
prospective violation of Environmental Laws;
action or inaction by any federal, state or local
agency that delays or prevents the issuance or
granting of any approval or authorization required
to conduct Operations (including, without
limitation, a failure to complete any review and
analysis required by the National Environmental
Policy Act or any similar state law); acts of war
or conditions arising out of or attributable to
war, whether declared or undeclared; acts of
terrorism, riot, civil strife, insurrection or
rebellion; fire, explosion, earthquake, storm,
flood, sink holes, drought or other adverse
weather condition; delay or failure by suppliers
or transporters of materials, parts, supplies,
services or equipment or by contractors' or
subcontractors' shortage of, or inability to
obtain, labor, transportation, materials,
machinery, equipment, supplies, utilities or
services; accidents; breakdown of equipment,
machinery or facilities; actions by native rights
groups, environmental groups, or other similar
special interest groups; or any other cause
whether similar or dissimilar to the foregoing.
The affected Member shall promptly give notice to
the other Members of the suspension of
performance, stating therein the nature of the
suspension, the reasons therefore, and the
expected duration thereof. The affected Member
shall resume performance as soon as reasonably
possible. During the period of suspension the
obligations of all Members to advance funds
pursuant to this Agreement shall be reduced to
levels consistent with then current Operations.

16.8  Rule Against Perpetuities.  The Members do
not intend that there shall be any violation of
the rule against perpetuities, the rule against
unreasonable restraints on the alienation of
property, or any similar rule. Accordingly, if any
right or option to acquire any interest in the
Properties or Assets, in an Ownership Interest, or
the Company, or in any real property exists under
this Agreement, such right or option must be
exercised, if at all, so as to vest such interest
within time periods permitted by applicable rules.
If, however, any such violation should
inadvertently occur, the Members hereby agree that
a court shall reform that provision in such a way
as to approximate most closely the intent of the
Members within the limits permissible under such
rules.

16.9  Further Assurances.  Each of the Members
shall take, from time to time and without
additional consideration, such further actions and
execute such additional instruments as may be
reasonably necessary or convenient to implement
and carry out the intent and purposes of this
Agreement or as may be reasonably required by
lenders in connection with Project Financing.

16.10  Entire Agreement; Successors and Assigns.
This Agreement contains the entire understanding
of the Members and supersedes all prior agreements
and understandings between the Members relating to
the subject matter hereof. This Agreement shall be
binding upon and inure to the benefit of the
respective successors and permitted assigns of the
Members.

16.11  Counterparts.  This Agreement may be
executed in any number of counterparts, and it
shall not be necessary that the signatures of both
Members be contained on any counterpart. Each
counterpart shall be deemed an original, but all
counterparts together shall constitute one and the
same instrument.

IN WITNESS WHEREOF, the parties hereto have
executed this Agreement as of the Effective Date.
