Ownership Interests, and in accordance with Section 3.14 of Exhibit B, with
all reasonably anticipated costs of future reclamation, closure and
Environmental Compliance. No Member who has resigned or withdrawn from the
Company will be required to contribute additional funds to the
Environmental Compliance Fund unless and until all contribution made to
said Environmental Compliance Fund prior to such withdrawal or resignation
have been spent or committed to be spent.

(q) The Manager shall otherwise conduct Operations as it deems appropriate
in its discretion.

The Manager shall not be in default of any duty under this Section 9.2 if
its failure to perform results from the failure of the Members to perform
acts or to contribute amounts required of them by this Agreement.

9.3 Standard of Care; Indemnification. The Manager shall conduct all Operations
in a good, workmanlike and efficient manner, in accordance with sound mining and
other applicable industry standards and practices, and in accordance with the
terms and provisions of leases, licenses, permits, contracts and other

agreements pertaining to the Assets. The Manager shall not be liable to the
non-managing Member for any act or omission resulting in damage or loss except
to the extent caused by or attributable to the Manager's willful misconduct or
gross negligence. The Members shall indemnify and hold harmless the Manager and
its officers, employees and agents from and against any liabilities,
obligations, claims, responsibilities, actions, demands, losses, costs or
expenses, including but not limited to costs of litigation and reasonable
attorneys fees, arising out of or relating to its activities as Manager, except
that any liabilities or obligations arising directly from the Manager's gross
negligence or willful misconduct shall be excluded form this indemnity.

9.4 Resignation; Deemed Offer to Resign. The Manager may resign upon three
months' prior notice to the other Member, in which case the other Member may
elect to become the new Manager by notice to the resigning Member within 30 days
after the notice of resignation. In the case of any resignation as Manager by
TSVLP, USEC shall be deemed to be the other Member and TSVLP shall be deemed to
be the resigning Member for purposes of this Section 9.4. If any of the
following shall occur, the Manager shall be deemed to have offered to resign,
which offer shall be accepted by the other Member, if at all, within 90 days
following such deemed offer:

(a) The Ownership Interest of the Member who serves or who appoints the
Manager shall become less than fifty percent (50%); or

(b) The Manager fails to perform a material obligation imposed upon it
under this Agreement and such failure continues for a period of 30 days
after notice from the other Member demanding performance; or

(d) A receiver, liquidator, assignee, custodian, trustee, sequestrator or
similar official for a substantial part of its assets is appointed and such
appointment is neither made ineffective nor discharged within 60 days after
the making thereof, or such appointment is consented to, requested by, or
acquiesced in by the Manager; or

(e) The Manager commences a voluntary case under any applicable bankruptcy,
insolvency or similar law now or hereafter in effect; or consents to the
entry of an order for relief in an involuntary case under any such law or
to the appointment of or taking possession by a receiver, liquidator,
assignee, custodian, trustee, sequestrator or other similar official of any
substantial part of its assets; or makes a general assignment for the
benefit of creditors; or fails generally to pay its or Company debts as
such debts become due; or takes corporate or other action in furtherance of
any of the foregoing; or

(f) Entry is made against the Manager of a judgment, decree or order for
relief affecting a substantial part of its assets by a court of competent
jurisdiction in an involuntary case commenced under any applicable
bankruptcy, insolvency or other similar law of any jurisdiction now or
hereafter in effect.

9.5 Payments To Manager. The Manager shall be compensated for its services and
reimbursed for its costs hereunder in accordance with the Accounting Procedure.

9.6 Transactions With Affiliates. If the Manager engages Affiliates to provide
services hereunder including, without limitation, services relating to milling
or beneficiating Products, it shall do so on terms no less favorable to the
Company than would be the case with unrelated persons in arm's-length
transactions.

9.7 Activities During Deadlock. Subject to the contrary direction of the
Management Committee and to the receipt of necessary funds, if the Management
Committee for any reason fails to adopt a Program and Budget, the Manager shall
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.

ARTICLE X
PROGRAMS AND BUDGETS

10.1 Operations Pursuant to Programs and Budgets. Operations shall be conducted,
expenses shall be incurred, and Assets shall be acquired only pursuant to
adopted Programs and Budgets.

10.2 Presentation of Programs and Budgets. Proposed Programs and Budgets shall
be prepared by the Manager for a period of one (1) year or any longer period.
Each adopted Program and Budget, regardless of length, shall be reviewed at
least once a year at the annual 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.

10.3 Review and Adoption of Proposed Programs and Budgets. Within thirty (30)
days after submission of a proposed Program and Budget, or a proposed Amendment
thereto under Section 10.9, each Member shall submit in writing to the
Management Committee:

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

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

If a Member fails to give any of the foregoing responses within the
allotted time, the failure shall be deemed to be a vote by the Member for
adoption of the Manager's proposed Program and Budget. If a 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 possible development of a Program and Budget acceptable to all Members
(provided that no Member 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 a Program and Budget
by majority vote of Ownership Interests.

10.4 Emergency or Unexpected Expenditures. In case of emergency, the Manager may
take any reasonable action it deems necessary to protect life, limb or property,
to protect the Assets or to comply with Environmental Laws or other Laws. The
Manager may 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 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.

10.5 Amendments to Programs and Budgets. An adopted Program and Budget may be
amended by the Manager (the Amendment) upon 30 days notice. The procedures for
review and approval of proposed Amendments under this Section 10.5 shall be the
same as the procedures for the review and approval of proposed Budgets and
Programs under Section 10.3.

ARTICLE XI
ACCOUNTS AND SETTLEMENTS

11.1 Monthly Statements. The Manager shall promptly submit to the Management
Committee monthly statements of account reflecting in reasonable detail the
charges and credits to the Business Account during the preceding month.

11.2 Cash Calls. On the basis of each adopted or amended Program and Budget and
subject to Section 10 of this Agreement and Section 2.2 of the Members'
Agreement as Amended, the Manager shall submit to each Member, a billing (or
cash call) for estimated cash requirements for each month during the term of
such Program. Within ten (10) days after receipt of each such billing, each
Member shall pay to the Manager its share of such estimated requirements. Time
is of the essence of payment of such ▇▇▇▇▇▇▇▇. The Manager shall at all times
maintain a reasonable working capital reserve. All funds reasonably in excess of
immediate cash requirements may be invested in interest-bearing accounts with
the Company's bank, for the benefit of the Business Account.

11.3 Failure to Meet Cash Calls. A Member that fails to meet cash calls in the
amount and at the times specified in Section 11.2 shall be in default, and the
amounts of the defaulted cash call shall bear interest from the date due at an
annual rate equal to the Interest Rate, but in no event shall said rate of
interest exceed the maximum permitted by Law.

11.4 Audits. Unless waived by all Members in writing, the Manager shall order an
audit of the accounting and financial records for each calendar year (or other
mutually agreed accounting period). All written exceptions to and claims upon
the Manager for discrepancies disclosed by such audit shall be made not more
than 3 months after receipt of the audit report. Failure to make any such
exception or claim within the 3-month period shall mean the audit is correct and
binding upon the Members. The audits shall be conducted by a firm of certified
public accountants selected by the Manager, unless otherwise agreed by the
Management Committee.

ARTICLE XII
PROPERTIES; DISTRIBUTION OF PRODUCTION

12.1 Royalties, Production Taxes and Other Payments Based on Production. All
required payments of production royalties, taxes based on production of
Products, and other payments out of production to private parties and
governmental entities, shall be determined and made by the Company in a timely
manner and otherwise in accordance with applicable laws and agreements. The
Manager shall furnish to the Members evidence of timely payment for all such
required payments. In 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 subrogated to the rights of such third party; provided, however, that the
making of any such payment on behalf of the Company shall not constitute
acceptance by the paying Member of any liability to such third party for the
underlying obligation.

12.2 Abandonment and Surrender. Either Member may request the Management
Committee to authorize the Manager to surrender or abandon part or all of the
Properties. If the other Member objects to such surrender or abandonment, then
at the option of the objecting Member, the Company shall assign to the objecting
Member or such other Person as the objecting Member specifies, by special
warranty deed and without cost to the surrendering Member, all of the Company's
interest in the Properties sought to be abandoned or surrendered, free and clear
of all Encumbrances created by, through or under the Company or the surrendering
Member, other than those to which both Members have agreed. Upon the assignment,
such properties shall cease to be part of the Properties.

12.3 Reacquisition. If any Properties are abandoned or surrendered under the
provisions of this Article XII, then, unless this Agreement is earlier
terminated, neither Member nor any Affiliate thereof shall acquire any interest
in such Properties or a right to acquire such Properties for a period of two
years following the date of such abandonment or surrender. If a Member
reacquires any Properties in violation of this Section 12.3, the other Member
may elect by notice to the reacquiring Member within 45 days after it has actual
notice of such reacquisition, to have such properties made subject to the terms
of this Agreement and transferred, without charge, to the Company. In the event
such an election is made, the reacquired properties shall thereafter be treated
as Properties, and the costs of reacquisition shall be borne solely by the
reacquiring Member and shall not be included for purposes of calculating the
Members' respective Ownership Interests.

12.4 Disposition of Products by Manager. The Manager shall market and dispose of
Products. Such dispositions by Manager shall be in good faith and in accordance
with good industry practice, with the objective of obtaining the best possible
price for the Products. The Manager shall have the right to enter into forward
sales and hedging arrangements as approved by the Management Committee.

ARTICLE XIII

13.1 Business Information. All Business Information shall be owned jointly by
the Members as their Ownership Interests are determined pursuant to this

other Member. Each Member shall keep confidential and not disclose to any third
party or the public any portion of the Business Information that constitutes
Confidential Information.

13.2 Disclosure Required By Law. Notwithstanding anything contained in this
Article, a Member may disclose any Confidential Information if, in the opinion

pursuant to a valid subpoena or other applicable order; or (b) such disclosure
is legally required to be made pursuant to State or Federal Securities Laws or
the rules or regulations of a stock exchange or similar trading market
applicable to the disclosing Member.

Prior to any disclosure of Confidential Information under this Section 13.2, the
disclosing Member shall give the other Member at least three (3) business days
prior written notice (unless less time is permitted by such rules, regulations
or proceeding) and, in making such disclosure, the disclosing Member shall
disclose only that portion of Confidential Information required to be disclosed
and shall take all reasonable efforts to preserve the confidentiality thereof,
including, without limitation, obtaining protective orders and supporting the
other Member in intervention in any such proceeding.

13.3 Public Announcements. Prior to making or issuing any press release or other
public announcement or disclosure of Business Information that is not
Confidential Information, a Member shall first consult with the other Member as
to the content and timing of such announcement or disclosure, unless in the good
faith judgment of such Member, there is not sufficient time to consult with the
other Member before such announcement or disclosure must be made under
applicable Laws; but in such event, the disclosing Member shall notify the other
Member, as soon as possible, of the pendency of such announcement or disclosure,
and it shall notify the other Member before such announcement or disclosure is
made if at all reasonably possible. Any press release or other public
announcement or disclosure to be issued by either Member relating to this
Business shall also identify the other Member.

13.4 Duration of Confidentiality. The provisions of this Article XIII shall
apply during the term of this Agreement and for two years following termination
of this Agreement pursuant to Section 14.1, and shall continue to apply to any
Member who withdraws, who is deemed to have withdrawn, or who Transfers its
Ownership Interest, for two years following the date of such occurrence.

14.4 Filing of Certificate of Cancellation. Upon completion of the winding up of
the affairs of the Company, the Manager shall promptly file a Certificate of

involuntarily, then a person selected by a majority vote of the Members to wind
up the affairs of the Company shall file the Certificate of Cancellation.

14.5 Right to Data After Dissolution. After dissolution of the Company pursuant
to Subsections 14.1(a), (b), or (c), each Member shall be entitled to make
copies of all applicable information acquired hereunder before the effective
date of termination not previously furnished to it.

14.6 Continuing Authority. On dissolution of the Company under Section 14.1 the
Member that was the Manager or that appointed the Manager prior to such
dissolution (or the other Member in the event of a resignation by the Manager)
shall have the power and authority to do all things on behalf of both Members
that are reasonably necessary or convenient to: (a) wind up Operations (b)
complete reclamation, closure and other Environmental Compliance activities with

respect to the Properties, and (c) complete any transaction and satisfy any
obligation, unfinished or unsatisfied, at the time of such dissolution, if the

time or change the method of payment of an already existing liability or
obligation, prosecute and defend actions on behalf of the Company and either or
both Members, encumber Assets, and take any other reasonable action in any
matter with respect to which the former Members continue to have, or appear or
are alleged to have, a common interest or a common liability.

ARTICLE XV

15.1 Governing Law. Except for matters of title to the Assets or their Transfer,
which shall be governed by the law of their situs, this Agreement shall be

that would permit or require the application of the laws of any other
jurisdiction.

are, unless otherwise stated, references to this entire Agreement.

16.5 Waiver. The failure of either Member to insist on the strict performance of

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

interest within time periods permitted by applicable rules. If, however, any

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.
