Item 2.  Acquisition or Disposition of Assets.

     (a)  Effective July 11, 1996, the Company acquired
     leasehold and other property interests in the
     Illinois Creek Project in north central Alaska from
     North Pacific Mining Corporation ("NPMC").  The
     Company made initial payments to NPMC totaling
     $100,000 in 1994 to evaluate the Illinois Creek
     property.  The Company entered into an agreement
     with NPMC effective December 16, 1994, which was
     amended on February 5, 1996 (the "Agreement").
     Pursuant to the Agreement, the Company agreed to
     make a $1,000,000 non-refundable payment to NPMC in
     cash or shares of the Company's $.001 par value
     common stock (the "Common Stock").  The Company
     elected to make the payment in Common Stock, and
     based upon an average market price of the Common
     Stock on The Nasdaq Stock Market as provided in the
     Agreement, the Company was required to issue to NPMC
     449,754 shares.  The Company also agreed that, upon
     obtaining the necessary permits and if no material
     adverse economic change had occurred, the Company
     would make a production decision and issue to NPMC
     an additional $3,000,000 in cash or Common Stock.
     The Company received the key permits related to the
     Project, and determined that no material adverse
     economic change had occurred with respect to the
     Project economics.  The Company made a production
     decision and agreed to issue to NPMC an additional
     1,090,909 shares of Common Stock.  The calculation
     of the number of shares was based on the average
     market price of the Common Stock on The Nasdaq Stock
     Market as provided in the Agreement.

          Effective July 11, 1996, the Company issued the
     aggregate of 1,540,663 shares of Common Stock to
     NPMC.  As a result of this transaction, NPMC owns
     approximately 9.5% of the Company's issued and
     outstanding Common Stock.  The Company also granted
     a security interest to NPMC in the property, which
     is subject to a subordination arrangement with the
     Company's lender on this Project.  See Item 5 below
     for a description of this facility.  The Company had
     also agreed with NPMC in the Agreement to file a
     Registration Statement relating to the resale of
     these shares, which Registration Statement has been
     filed and declared effective by the Securities and
     Exchange Commission.  The Company has agreed to use
     its best efforts to keep this Registration Statement
     effective until NPMC has sold these shares or until
     June 1999.

          In addition to the Common Stock, NPMC had the
     right to enter into a mining venture agreement with
     the Company in which the Company would transfer to
     NPMC an undivided 25% interest in the Illinois Creek
     Mining Leases, or to receive a 5% net returns
     royalty.  NPMC chose to receive a 5% net returns
     royalty on production from the Illinois Creek Upland
     Mining Lease.  No decision has been made regarding
     the property covered by the Illinois Creek Roundtop
     Mining Lease, which area has not yet been explored
     by the Company.

<PAGE>

          If the Company delineates the existence of
     additional ore reserves on the lease known as the
     Illinois Creek Upland Mining Lease, which increases
     the total proven ore reserves to at least 1,000,000
     ounces of equivalent gold ore reserves beyond the
     mineralization stated in the Company's February 1996
     feasibility report, then NPMC will have the right to
     elect to participate in subsequent mining operations
     with respect to those additional reserves for a 25%
     working interest by reimbursing the Company 120% of
     NPMC's 25% share of exploration, development and
     capital costs incurred by the Company subsequent to
     February 1996 which are directly related to
     delineation and/or production of the additional
     reserves.

          Pursuant to the Agreement, the Company has
     until December 16, 1997, to achieve "commercial
     production" which is defined as the delivery to a
     bona fide purchaser of minerals produced for a
     minimum period of 45 consecutive days at not less
     than 70% of the pro forma production capacity as set
     forth in the Project feasibility report.  This
     period may be extended at the option of the Company
     for two additional one-year periods upon payment by
     the Company of a $300,000 advance royalty, adjusted
     for inflation, for each one-year extension.  The
     Agreement terminates on December 16, 1999, if the
     Company has not achieved commercial production by
     that date.

          NPMC is a wholly-owned subsidiary of Cook Inlet
     Region, Inc., an Alaska Native Regional Corporation
     ("CIRI").  Except for the transactions involving the
     Illinois Creek Project, the Company has not had any
     material relationship with NPMC or CIRI and the
     Company is unaware of any material relationship
     between the Company's affiliates, any director or
     officer of the Company, or any associate of any such
     director or officer, with NPMC or CIRI.

          The Company has transferred its property
     interest in the Project to its wholly-owned
     subsidiary, USMX of Alaska, Inc. ("AK").  The
     Company intends to use its internal cash resources
     and the proceeds from borrowings to finance the
     development and construction costs of the Project.
     See Item 5 for a discussion of the Company's
     borrowings from N M Rothschild & Sons Limited.

          (b)  The Property acquired from NPMC consisted
     principally of leasehold interests in the Illinois
     Creek Project.  The Company has conducted
     exploration activities at the site since 1994.  The
     Company has received all necessary regulatory
     authorization and has commenced construction of the
     mining, processing and related facilities.  It is
     the Company's goal to commence mining in late
     summer, 1996.  The Company expects to conduct gold
     and silver mining operations on this property.

Item 5.  Other Events

          (a)  Effective July 11, 1996, the Company
     entered into credit agreements with N M Rothschild &
     Sons Limited (the "Lender") for a $22,000,000
     facility to finance the development and construction
     costs of the Illinois Creek Project (the "Project").
     The Company's wholly-owned subsidiary, AK, is the
     borrower of $19.5 million of the $22 million
     facility.  Under certain circumstances, the loan to
     AK may be in the form of a gold loan, in which event
     the maximum credit amount would be the number of
     ounces of gold equal to $19,500,000 divided by the
     price of gold in London.  However, the Company has
     agreed with NPMC that it will not convert the loan
     to a gold loan until such time as the Project has
     achieved commercial production as defined in the
     Agreement with NPMC.  See Item 2.  Advances will be
     made by the Lender solely to an account dedicated to
     Project operations and only if certain conditions
     related principally to Project operations are
     satisfactory to the Lender.  In addition, AK will be
     required to maintain a minimum balance in the
     Proceeds Account equal to the sum of:  (I) the
     greater of $1,500,000 or a formula amount based on
     the present value of future net cash flow from the
     Project, (II) the lesser of $250,000 or interest
     payable to the Lender for the following three
     months, (III) capital expenditures scheduled for the
     following three months and, (IV) any other payments
     due to the Lender for the following three months.
     It is expected that AK will need to deposit
     approximately $1,500,000 for deposit in the Proceeds
     Account by September 30, 1996, to maintain the
     minimum balance.  The Company has agreed to make a
     $1,500,000 equity contribution to AK by that date.

          AK will not be able to make withdrawals from
     the Proceeds Account for its general corporate
     purposes or to pay dividends until "Completion" has
     occurred.  The requirements for Completion include
     the construction of the Project facilities, which
     facilities and the equipment thereon must be
     mechanically complete and electrically operable
     ("Mechanical Completion"), the achievement of
     production amounts and grades, costs and reserves
     similar to the development plan, and the absence of
     any default in the credit agreement.  The note
     evidencing the $19.5 million obligation bears
     interest, payable quarterly, at 2.25% above LIBOR
     until Completion and 1.875% thereafter for the
     remainder of the approximate four-year term of the
     loan.  Principal payments will be made in eight
     amortized installments on September 30 and December
     31 of each year, commencing September 30, 1997.

          Subject to satisfaction of the requirements for
     maintenance of the Proceeds Account, advances will
     be made by the Lender to AK until the first to occur
     of September 30, 1997, or Mechanical Completion.  AK
     paid an establishment fee of $292,500 to the Lender.
     AK will also be required to pay a commitment fee of
     one-half of one percent of the difference between
     the principal amount outstanding and the maximum
     credit amount.

<PAGE>

          The balance of the facility is represented by a
     $2.5 million note made by the Company which may be
     converted into Common Stock at the conversion price
     of $3.40 per share at the option of the Lender at
     any time during the approximate four-year term of
     the note.  The Company may also require conversion
     if the note is not in default and the daily closing
     price of the Common Stock exceeds $4.75 for 30
     consecutive trading days.  A total of 735,294 shares
     of Common Stock (subject to adjustment for certain
     events) is reserved for issuance by the Company upon
     conversion of the $2.5 million loan.  The Company
     has also agreed to register the Common Stock for
     resale under certain circumstances.  During the term
     of the convertible note evidencing this loan, the
     Lender will have the opportunity to profit from an
     increase in the market price of the Common Stock
     with resulting dilution to the holders of Common
     Stock.  The existence of such convertible securities
     may adversely affect the terms on which the Company
     can obtain additional financing, and the holders of
     such convertible note can be expected to convert the
     securities at a time when the Company may be able to
     obtain additional capital by offering shares of the
     Common Stock on terms more favorable to the Company
     than those provided by the conversion of this note.
     The $2.5 million loan bears interest at 2% above
     LIBOR and will be payable no less frequently than
     semi-annually.

          In accordance with the requirements of the
     related credit agreements, the Company deposited the
     entire proceeds of the $2.5 million loan into the
     Proceeds Account and such proceeds are not available
     for general corporate purposes.  Payments may be
     made to the Company from the Proceeds Account in an
     amount sufficient for the Company to make interest
     payments.  AK will not be permitted to repay the
     $2.5 million to the Company or other advances by the
     Company in the approximate amount of $3.4 million
     unless certain conditions are satisfied, principally
     related to repayment of the notes to the Lender and
     satisfactory operation of the Project.  The Company
     has pledged to the Lender its stock in AK as well as
     its notes from AK for advances made by the Company.

          The Company is also a guarantor of the $19.5
     million loan to AK until it has been demonstrated
     that the Project is operating in a manner
     satisfactory to the Lender.  There can be no
     assurance when, or if, this will occur, and the
     Company could have a substantial debt burden without
     other resources to make repayment.  In addition, the
     Company will be a continuing guarantor of AK's
     covenant to comply with environmental laws.

          The Company's subsidiary, AK, must deliver to
     the Lender, among other things, financial
     information, reserve, hedging and operating reports,
     and must use all commercially reasonable efforts to
     maintain, develop and operate the Illinois Creek
     Project in accordance with the present development
     plan and prudent mining industry practices.  AK must
     also comply with applicable laws and maintain its
     property rights in the Project, including payment of
     royalties which may become due to NPMC.  In
     addition, except for limited circumstances, without

<PAGE>     
     
     the Lender's consent, AK may not incur any
     additional indebtedness, permit any liens on the
     Project, assume or guarantee indebtedness of others,
     invest in others, merge or change its capital
     structure, sell the assets of the Project, or permit
     Project reserves or future net cash flows to decline
     materially from the present development plan.  AK
     must also achieve Mechanical Completion by July 31,
     1997, and Completion by November 30, 1997.  Such
     restrictions could affect the Company's operations
     and future plans.

          The Company has also agreed with the Lender
     that, so long as the $2.5 million Note made by the
     Company is unpaid, or any other obligation of the
     Company remains unsatisfied, including the Company's
     Guaranty of the loan to AK, the Company will, among
     other things, comply with all applicable laws,
     provide the Lender with financial reports and
     continue to engage principally in the mining
     business.  In addition, except for limited
     circumstances, without the Lender's consent, the
     Company may not incur indebtedness (other than
     indebtedness after Completion to develop mining
     properties where the sole recourse of the lender is
     the mining property being developed), permit any
     liens on the Project, assume or guarantee
     indebtedness of others, invest in others, merge
     (unless after Completion and the Company is the
     survivor of the merger) or change its capital
     structure, pay dividends or sell the assets of the
     Project.  Such restrictions could affect the
     Company's operations and future plans.

          The Company has also agreed with the Lender
     that it shall not permit its (a) current ratio to be
     less than 2.0 to 1.0; (b) consolidated tangible
     stockholders' equity to be less than $17,500,000;
     and (c) total consolidated liabilities to exceed
     175% of its consolidated tangible stockholders'
     equity.

          There are substantial risk factors associated
     with the Project and the Company's future
     operations, including the substantial financial
     commitment made by the Company to the development of
     the Project, and the resultant strain on the
     Company's liquidity and capital resources, delays
     and other problems which may result from
     difficulties in transportation of equipment,
     supplies and personnel to the Project, potentially
     adverse weather conditions and potentially
     substantial costs to comply with environmental and
     other laws, as well as gold price volatility and
     other economic factors which are beyond the control
     of the Company.  Moreover, inasmuch as the Project
     has not been fully constructed and is not yet
     operational, there is no operating history upon
     which to base estimates of future cash operating
     costs and other operating requirements.
     Accordingly, the Company is exploring alternatives
     to provide additiional financing to enable it to
     continue work to commence mining on the Project in
     the near future, provide contingency funds for
     unforeseen delays or other Project problems, and to
     provide for future operations, including exploration
     and development activities on other properties.  The
     Company is reviewing alternative means of augmenting
     its capital base, but has no firm commitments for
     
<PAGE>
     
     other funding.  The failure to obtain other funding
     would have a material adverse effect on the Company.

year basis, at the Interest Rate or the Default Rate, as
applicable.

               (b)  Interest Periods.  USMX may select an
interest period with respect to the Loan ("Interest Period") of
30, 90 or 180 days, or of such other period of days as may be
agreed to by Lender in its sole discretion, on a 360-day year
basis.  USMX will select Interest Periods by giving notice to

Business Days prior to the expiration of the Interest Period then
in effect by an Interest Period Notice.  If at any time USMX
fails to give timely notice of its Interest Period selection,
then USMX shall be deemed to have selected an Interest Period of
30 days.  No Interest Period shall end after the Scheduled
Maturity Date.  Interest will be payable in full at the end of
each Interest Period.

               (c)  Default Interest.  Interest on the Loan shall
accrue and shall be payable by USMX at the Default Rate during
all periods when any amounts payable by USMX as principal repay
ments, interest payments or fee or expense payments are due and
payable hereunder, whether by acceleration or otherwise, but
remain unpaid by USMX; provided the Default Rate shall not apply
to past-due fees and expenses unless Lender has provided written
notice to USMX pursuant to Section 11.2, and such fees and
expenses remain due and unpaid for five (5) Business Days after
the giving of such notice.  Without prejudice to the rights of
Lender under the preceding sentence, USMX shall indemnify Lender
against any direct loss or expense (not including lost profits on
re-employment of capital) which Lender may sustain or incur as a

<PAGE>

result of the failure by USMX to pay when due the Principal
Amount of the Loan.  A certificate or other notice of Lender
submitted to USMX setting forth the basis for the determination
of Default Rate interest due and of the amounts necessary to
indemnify Lender in respect of such loss or expense, shall
constitute evidence of the accuracy of the information contained
therein in the absence of error and, absent notice from USMX of
such error, shall be conclusive and binding for all purposes.
Interest accruing at the Default Rate shall be payable on demand.

          3.4  Repayment of the Loan.

               (a)  Principal Repayment Generally.  USMX agrees
to repay the Loan as provided herein.  Except as provided by

Amount of the Loan prior to the Scheduled Maturity Date.

other terms hereof pertaining to mandatory prepayments of the
Loan, USMX will make payment in full of the unpaid Principal
Amount of the Loan not later than the Scheduled Maturity Date.

               (c)  Mandatory Prepayment Upon Loan Acceleration.
USMX will repay the Loan in full, together with accrued interest
thereon, Breakage Costs and fees, upon acceleration of the
Scheduled Maturity Date of the Loan by Lender pursuant to Section

          3.5  Priority of Prepayments.  All prepayments made by
USMX pursuant to Section 3.4(c) shall be accompanied by payment
of Lender's Breakage Costs, and shall be applied first to accrued
and unpaid interest on the Loan as of the end of the most recent
Interest Period, then to any other amounts then payable by USMX
hereunder including Breakage Costs and fees, then to the
Principal Amount.

          3.6  Increased Costs and Reduction in Return.  If due
to (a) the introduction of, or any change (including, without
limitation, any change by way of imposition or increase of
reserve requirements) in, or in the interpretation of, any law or
regulation or (b) the compliance by Lender with any guideline or
request from any central bank or other governmental agency having
jurisdiction over Lender (whether or not having the force of
law), collectively referred to as "Governmental Acts," there
shall be any increase in the cost or reduction in return to
Lender of agreeing to make or making, funding or maintaining the
Loan, then USMX shall from time to time, upon demand by Lender,
pay to Lender additional amounts sufficient to indemnify it
against such increased costs or reduction in return; provided
that Lender agrees to use reasonable efforts to mitigate the
increased cost or reduction in return to the extent reasonably
practicable.  A certificate as to the amount of such increased
cost or reduced return, submitted to USMX by Lender, shall be
conclusive absent manifest error.

          3.7  Payments and Computations.  USMX shall make each
payment due hereunder and under the Convertible Note in
immediately available funds not later than 5:00 p.m. (New York

USMX hereby authorizes Lender, if and to the extent payment of
money owed to it is not made when due hereunder or under the
Convertible Note, to charge from time to time against USMX's
accounts with Lender any amount so due.  All computations of
interest hereunder shall be made on the basis of a year of 360
days for the actual number of days elapsed (including the first
day but excluding the last day).

          3.8  Payment on Non-Business Days.  Whenever any
payments to be made hereunder or under the Convertible Note shall
be stated to be due on a day which is not a Business Day, such
payment may be made on the next succeeding Business Day, and such
extension of time shall in such case be included in the
computation of payment of interest or fees, as the case may be,
unless such next succeeding Business Day is after the end of the
Interest Period, in which case the payment will be made on the
next preceding Business Day and such payment shall not reflect
the actual payment date in the computation of interest or fees
due and payable.

          3.9  Taxes.

               (a)  General.  Any and all payments by USMX
hereunder shall be made free and clear of and without deduction

of America or any other jurisdiction under the laws of which
Lender is otherwise subject to tax, or any political subdivision
thereof (all such non-excluded taxes, levies, duties, imposts,
deductions, charges, withholdings and liabilities being
hereinafter referred to as "Taxes").  If USMX shall be required
by law to deduct any Taxes from or in respect of any sum payable
hereunder to Lender, (i) the sum payable shall be increased as
may be necessary so that after making all required deductions
(including deductions applicable to additional sums payable under
this Section 3.9) Lender receives an amount equal to the sum it
would have received had no such deductions been made, (ii) USMX
shall make such deductions and (iii) USMX shall pay the full
amount deducted to the relevant taxation authority or other
authority in accordance with applicable law.  The foregoing
obligation of USMX will apply with respect to any assignee of
Lender.

               (b)  Other Taxes.  In addition, USMX agrees to pay
any present or future stamp, sales, use or documentary taxes or
any other excise or property taxes, charges, duties or similar
levies which arise from any payment made hereunder or from the

<PAGE>

execution, delivery or registration of, or otherwise with respect
to, this Agreement, any of the Loan Documents, or any Instrument
contemplated thereby (hereinafter referred to as "Other Taxes").
To Lender's knowledge, no Other Taxes will be applicable to the
transactions contemplated by this Agreement.

               (c)  Tax Indemnity.  USMX hereby indemnifies
Lender for the full amount of Taxes and Other Taxes (including,
without limitation, any Taxes or Other Taxes imposed by any
jurisdiction on amounts payable under this Section 3.9) paid by
Lender and any liability (including penalties, interest and
expenses) arising therefrom or with respect thereto.  Lender
shall use commercially reasonable efforts to mitigate any Taxes
or Other Taxes to the extent practicable, and to refund to USMX
its proportionate share of any Taxes or Other Taxes paid by USMX
pursuant hereto ultimately refunded to Lender.

               (d)  Payment of Taxes.  Within 30 days after the
date of any payment of Taxes or Other Taxes withheld by USMX in
respect of any payment to Lender, USMX will furnish to Lender the
original or a certified copy of a receipt evidencing payment
thereof.

               (e)  Lender's Taxes.  To Lender's knowledge, under
applicable law and treaties in effect as of the date hereof
between the United States and the United Kingdom, no United
States federal taxes will be required to be withheld by USMX with
respect to any payment to be made to Lender in respect of this
Agreement.  Lender agrees upon written request of USMX to deliver
to USMX, in duplicate, duly completed and signed copies of either
Form 1001 (relating to Lender and entitling Lender to a complete
exemption from withholding on all amounts to be received by
Lender pursuant to this Agreement, the Loans and Notes as a
result of a tax treaty concluded with the United States) or Form
4224 (relating to all amounts to be received by Lender pursuant
to this Agreement, the Loan and the Convertible Note) of the
Internal Revenue Service.

               (f)  Survival.  Without prejudice to the survival
of any other agreement hereunder, the agreements and obligations
contained in this Section 3.9 shall survive the payment in full
of the Loan and interest hereunder.

demand, provisional or final) at any time held and other
indebtedness at any time owing by Lender to or for the credit or
the account of USMX against any and all of the Obligations of
USMX now or hereafter existing, although such Obligations may be
contingent and unmatured.  Lender agrees promptly to notify USMX
after any such set-off and application, provided that the failure
to give such notice shall not affect the validity of such set-off
and application.  The rights of Lender under this Section 4.5 are
in addition to other rights and remedies (including, without
limitation, other rights of set-off) which Lender may have.

          4.6  Additional Collateral.  USMX and Lender intend
that the Security Documents cover and extend to all property
rights and interests of USMX, real or personal, tangible or
intangible, presently held or hereafter acquired which are
related to the Mining Properties, the production therefrom,
Hedging Contracts related to the Project and the proceeds of all
of the foregoing.  In the event that USMX acquires any additional
property right or interest related to the Mining Properties, the
production therefrom or Hedging Contracts related to the Project
which is not subject to the Lien of the Security Documents, upon
request therefor from Lender, USMX shall promptly execute, and
deliver such Instruments and take such actions as Lender may
reasonably request in order to perfect a first and prior Lien
(subject to Permitted Liens) on such right or interest.  Whether
or not Lender requests that any such right or interest be
subjected to the Security Documents, USMX agrees to keep such
rights or interests free and clear of all Liens other than
Permitted Liens.

                 REPRESENTATIONS AND WARRANTIES

          6.1  Representations and Warranties of USMX.  USMX
represents and warrants as follows:

               (a)  Organization, Qualification and Subsidiaries.
USMX is a corporation duly incorporated, validly existing and in
good standing under the laws of the State of Delaware and AK is a
corporation duly incorporated, validly existing and in good
standing under the laws of the State of Alaska.  Each of USMX and
AK has all requisite corporate power and authority to enter into
the Loan Documents to which it is a party and to carry out the
transactions contemplated thereby.  Each of USMX and AK is duly
qualified to do business as a foreign corporation in each
jurisdiction where the nature of its business or properties
requires such qualification.  Neither USMX nor AK has any
Subsidiaries, except as listed on Schedule 6.1(a).

               (b)  Authorization; No Conflict.  The execution,
delivery and performance by USMX and AK of the Loan Documents to
which they are respectively party have been duly authorized by
all necessary corporate action on the part of USMX and AK, and do
not and will not (i) require any consent or approval of the
stockholders of USMX or AK which have not been obtained;
(ii) contravene USMX's or AK's articles of incorporation,

<PAGE>

charter, bylaws or other such constituent document; (iii) violate
any provision of any law, rule, regulation (including, without
limitation, Regulations G, T, U and X of the Board of Governors
of the Federal Reserve System), order, writ, judgment,
injunction, decree, determination or award presently in effect
having applicability to USMX or AK; (iv) result in a breach of or
constitute a default under or require the consent of any party
which has not been obtained pursuant to any indenture or loan or
credit agreement or any other agreement, lease or instrument to
which USMX or AK is a party or by which either of them or their
properties may be bound or affected; or (v) result in, or
require, the creation or imposition of any Lien (other than Liens
arising under the Security Documents) upon or with respect to any
of the properties now owned by USMX or AK; and, to the best
knowledge of USMX, neither USMX nor AK is in breach or default in
any material respect under any such law, rule, regulation, order,
writ, judgment, injunction, decree, determination or award or any
such indenture, agreement, lease or instrument.

               (c)  Governmental Consents.  No authorization or
approval or other action by, and no notice to or filing with, any
Governmental Authority is required (i) for the due execution and
delivery of, and due performance of, the financial obligations of
USMX or AK under any Loan Document, or (ii) for the due
performance of all other obligations of USMX or AK under any of
the Loan Documents (other than registrations or filings to
perfect the liens created by the Security Documents and to
register the Conversion Shares pursuant to the Registration
Rights Agreement) except such authorizations, approvals or other
actions as have been obtained or notices or filings as have been
made.  All material Project Permits are identified in Schedule
6.1(c).  All Project Permits have been duly issued to or are held
by USMX or AK, are valid and in good standing and free of any
violation thereof by USMX and AK that upon disclosure, notice or
the passage of time could result in a delay in the commencement
of the Project or otherwise have a Material Adverse Effect on the
Project, and neither USMX nor AK have received any notice of an
asserted violation or proposed revocation, withdrawal or material
modification thereof.

               (d)  Binding Obligations.  Each of the Loan
Documents when delivered hereunder will be the legal, valid and
binding obligations of USMX or AK, as the case may be,
enforceable against USMX and AK in accordance with such documents
respective terms (except as limited by applicable bankruptcy,
insolvency, reorganization, moratorium and similar laws or
equitable principles affecting enforcement of creditors' rights
generally at the time in effect).

               (e)  Litigation.  Except as indicated in
Schedule 6.1(e), there is no action, proceeding or investigation
pending or threatened in writing against or involving USMX or AK
which alleges the violation of any laws, including Environmental
Laws, or which questions the validity of this Agreement, or any
of the Loan Documents, or any action taken or to be taken
pursuant to this Agreement, or any of the Loan Documents, or
which questions the nature or extent of USMX's or AK's equitable
or record title to the Mining Properties or assets related
thereto, or to the AK Shares, or which might result, either in
any case or in the aggregate, in any Material Adverse Effect on
the business, operations, condition (financial or otherwise),
aggregate properties or aggregate assets of USMX or AK, or in any
material liability on the part of USMX or AK.

<PAGE>

               (f)  Financial Statements; No Material Adverse
Change.  The audited consolidated balance sheet of USMX
(including AK) as of December 31, 1995, and the related
consolidated statements of income, cash flow and stockholders'
equity of USMX (including AK) for the year then ended, audited by
KPMG Peat Marwick LLP, and the unaudited consolidating balance
sheet of USMX (including AK) as of March 31, 1996, and the
related unaudited consolidating statement of income, cash flow
and stockholders' equity of USMX for the period then ended
certified by the chief financial officer of USMX, copies of which
have been furnished to Lender, fairly present the financial
condition of USMX as at such date and the results of the
operations of USMX for the period ended on such date, all in
accordance with GAAP consistently applied.  Neither USMX nor AK
have on the date hereof any material Contingent Liability or
liability for taxes, long-term leases or unusual forward or long-
term commitments which are not reflected in such financial
statements or listed in Schedule 6.1(f).  Since December 31,
1995, except as previously disclosed in writing to Lender,
neither the business, operations or prospects of USMX, nor any of
its properties or assets, have been affected by any occurrence or
development (whether or not insured against) which would result,
either in any case or in the aggregate, in a Material Adverse
Effect on USMX.  The unaudited consolidating balance sheet and
statement of cash flow of AK as of March 31, 1996, and the
related unaudited consolidating statement of income and retained
earnings of AK for the period then ended, copies of which have
been furnished to Lender, fairly present the financial condition
of AK as at such date and the results of the operations of AK for
the period ended on such date, all in accordance with GAAP
consistently applied.  AK has on the date hereof no material
Contingent Liability or liability for taxes, long-term leases or
unusual forward or long-term commitments which are not reflected
in such financial statements or listed in Schedule 6.1(f).  Since
December 31, 1995, except as previously disclosed in writing to
Lender, neither the business, operations or prospects of AK, nor
any of its properties or assets, have been affected by any
occurrence or development (whether or not insured against) which
would result, either in any case or in the aggregate, in a
Material Adverse Effect on AK.

               (g)  Other Agreements.  Neither USMX nor AK is a
party to any indenture, loan or credit agreement or any lease or
other agreement or instrument (other than the Material
Agreements) or subject to any charter or other corporate
restriction which would, upon a default thereunder or otherwise,
result in a Material Adverse Effect on USMX or AK, or materially
impair the ability of USMX or AK to carry out their respective
Obligations under this Agreement, or any of the Loan Documents.

               (h)  Information Accurate.  Except as disclosed to
Lender on Schedule 6.1(h) hereto, none of the information
delivered to Lender by USMX or AK in connection with the
transactions contemplated by this Agreement and the AK Credit
Agreement, including all representations and warranties, contains
any material misstatement of fact or omits to state a material
fact, and all projections contained in any such information,
exhibits or reports (including in particular the Feasibility
Study and the Development Plan), were based on information which
when delivered was, to the best knowledge of USMX, true and
correct, and to the best knowledge of USMX all calculations
contained in such projections were accurate, and such projections
presented USMX's then-current estimate of its future business,

<PAGE>

operations and affairs and, since the date of the delivery of
such projections, to the best knowledge of USMX, there has been
no material change in the assumptions underlying such
projections, or the basis therefor or the accuracy thereof.

               (i)  Title to Properties; Liens.

                    (i)  With respect to the Mining Properties
owned by USMX and AK which are subject to any of the Security
Documents, the Second Mortgage or the Fourth Mortgage, USMX and
AK are in exclusive possession of and own such properties free
and clear of all material defects of title, burdens on production
or Liens, except Liens disclosed in Schedule 6.1(i) and
specifically identified in the Security Opinion delivered by USMX
pursuant hereto.

                    (ii) With respect to the Mining Properties
held under leases or other contracts which are subject to any of
the Security Documents:  (A) USMX and AK are in exclusive
possession of such properties other than the airstrip located on
those properties and any navigable waters; (B) neither USMX nor
AK has received any notice of, and has no knowledge of any facts
or circumstances that, with the passage of time or notice, or
both, could result in default of any of the terms or provisions
of such leases or contracts; (C) under such leases and contracts
USMX or AK (as the case may be) has the authority to perform
fully, and no provision of any such lease prohibits or would be
breached by USMX's or AK's performance of, their respective
obligations under this Agreement and the other Loan Documents;
(D) to the best of USMX's knowledge and belief, such leases and
contracts are valid and are in good standing; and (E) to the best
of USMX's knowledge and belief, the properties covered thereby
are free and clear of all defects of title or Liens, except for
those specifically identified in the Security Opinion or
disclosed in Schedule 6.1(i) hereto.  USMX has delivered or will
make available to Lender all information concerning title to the
properties in USMX's or AK's possession or control, or to which
USMX or AK has access, which Lender requests.

                    (iii)     With respect to mining claims,
leases and other property interests (for purposes of this Section

both, required to hold the Claims have been paid or performed in
a manner consistent with generally accepted standards of major
companies in the mining industry through the assessment year
ending August 31, 1996; (C) all maintenance fee or rental
payments have been duly and timely made in order to maintain such
Claims through August 31, 1996; (D) all affidavits of assessment
work or other filings required to maintain the Claims in good
standing have been timely recorded or filed with the appropriate
Governmental Authorities; and (E) USMX has no knowledge of
conflicting claims, except overlaps to avoid gaps or to maintain
parallel end lines, or inadvertent overstakings which do not
impair USMX's property position.

<PAGE>

                    (iv) Except as disclosed on Schedule 6.1(i),
no approval or consent of any Governmental Authority or any other
party is necessary to authorize the execution and delivery of any
Loan Document or any other Instrument constituting or evidencing
obligations under this Agreement or the AK Credit Agreement.

               (j)  Securities Activities.  The proceeds of the
Loan hereunder will not be used to acquire any security in any
transaction which is subject to Sections 13 and 14 of the
Securities Exchange Act of 1934, as amended.  USMX is not engaged
in the business of extending credit for the purpose of purchasing
or carrying margin stock (within the meaning of Regulation X of
the Federal Reserve Board) or carrying any margin stock.

               (k)  Solvency.  USMX is not entering into the
arrangements contemplated by this Agreement or any of the other
Loan Documents with actual intent to hinder, delay or defraud
either present or future creditors.  On and as of the date
hereof, and thereafter on and as of the date of the undertaking
of any actions contemplated by this Agreement, including, without
limitation, the Advance of the Loan, after giving effect to the
Loan, and all such Instruments, and to any fees and expenses in
connection with such undertaking, (i) USMX's property at a fair
valuation, is, and will be, greater than the sum of its
Indebtedness (including its Contingent Liabilities); (ii) the
present fair salable value of USMX's assets exceeds, and will
exceed, the probable liability of USMX on its Indebtedness
(including its Contingent Liabilities) as they become absolute
and mature; (iii) USMX has not, and will not have, incurred, and
does not intend to, or believe that it will, incur debts
(including its Contingent Liabilities) beyond its ability to pay
such debts as such debts mature (taking into account the timing
and amounts of cash to be received by USMX from any source, and
of amounts to be payable on or in respect of its debts), and the
cash available to USMX after taking into account all other
anticipated uses of the cash, is, and is anticipated to be,
sufficient to pay all such amounts on or in respect of such debts
(including its Contingent Liabilities), when such amounts are
required to be paid; and (iv) subject to receipt of the Loan,
USMX has sufficient capital with which to conduct its business
and USMX's capital does not constitute unreasonably small capital
with which to conduct its business.  As used in
clauses (i) through (iv) above, the terms therein shall have the
meanings as used in Section 548 of the United States Bankruptcy
Code, the Uniform Fraudulent Conveyance Act and any applicable
state law concerning fraudulent conveyances as such may from time
to time have been amended or developed by judicial interpretation
to the date the representations herein are made.

               (l)  USMX's and AK's Capital Structure.  USMX and
AK have the number of authorized, issued and outstanding shares

shares or interests identified in such Schedule were duly and
validly issued and are non-assessable.  Except as indicated in
Schedule 6.1(l), USMX and AK have no outstanding warrants or
other obligations to issue additional shares or other equity
interests, including any stock or securities convertible into or
exercisable or exchangeable for any shares of their respective
capital stock or any rights or options to purchase any of the
foregoing, or to convert any existing Indebtedness to equity
interests in USMX or AK.

               (m)  Hedging Contract Obligations.  Except as set

in effect for Gold.

               (n)  Material Agreements; Absence of Default.  All

the Material Agreements and has not received any notice of an
asserted default thereunder from any other Person that is a party
to any such agreement.

               (o)  Taxes and Other Payments.  USMX and AK have
filed all tax returns (including all property tax returns and
other similar tax returns applicable to the Mining Properties)
and reports required by law to have been filed by either of them
and have paid all taxes and governmental charges thereby shown to
be owing and due, and all claims for sums due for labor,
material, supplies, personal property and services of every kind
and character provided with respect to, or used in connection
with the Mining Properties and no claim for the same exists
except as permitted hereunder, except any such taxes, charges or
amounts which are being diligently contested in good faith by
appropriate proceedings and for which adequate reserves in
accordance with GAAP have been set aside on the books of USMX or
AK, or for which failure to file any return or pay any tax or
charge could not have a Material Adverse Effect on the Project or
materially delay commencement of the Project.

               (p)  Development Plan.  The Development Plan has
been prepared in accordance with prudent mining practices and
after diligent inquiry by USMX, and USMX is not aware of any
facts or state of affairs which would materially hinder or
prevent USMX or AK from operating the Mining Properties in
accordance with the Development Plan and achieving, after
allowance for existing royalty burdens, the net gold production
provided for therein.

of information concerning USMX, AK, their properties, business
and prospects.

                    (ii) all facilities and property (including
underlying groundwater) comprising the Mining Properties have
been, and continue to be, owned, operated, leased or utilized by
USMX and AK in material compliance with all applicable laws,
including Environmental Laws; and

                    (iii)     with respect to the Mining
Properties, there have been no past, and there are no pending or
threatened claims, complaints, notices or requests for
information received by USMX or AK with respect to any alleged
violation of any law, including Environmental Laws.

               (r)  USMX's and AK's Indebtedness.  Except as
disclosed on Schedule 6.1(r) or specifically identified in the
financial statements of USMX and AK identified in Section 6.1(f),
USMX and AK have no existing Indebtedness which is not in the
ordinary course of business.

<PAGE>

               (s)  Employee Benefit Plans.  Except as disclosed
on Schedule 6.1(s), USMX has not established, does not maintain
and has made no contributions to, nor has any liability with
respect to, any Plan

               (t)  Insurance.  USMX maintains in effect the
insurance identified in Schedule 7.4, and such insurance is with
responsible and reputable insurance companies or associations in
such amounts and covering such risks as is prudent and consistent
with good operating practices.

          6.2  Representations and Warranties of Lender.  Lender
represents and warrants as follows:

               (a)  Authorization.  Lender has full power and
authority to enter into this Agreement and each of the Loan
Documents when delivered hereunder will be the legal, valid and
binding obligations of the Lender enforceable against the Lender
in accordance with such documents' respective terms (except as
limited by applicable bankruptcy, insolvency, reorganization,
moratorium and similar laws generally at the time in effect).

               (b)  Purchase Entirely for Own Account.  This
Agreement is made with the Lender in reliance upon the Lender's
representation to USMX, which by the Lender's execution of this
Agreement Lender hereby confirms, that the Convertible Note to be
received by Lender and the Common Stock issuable upon conversion
thereof (collectively, the "Securities") will be acquired for
investment for Lender's own account, not as a nominee or agent,
and not with a view to the resale or distribution of any part
thereof, and that Lender has no present intention of selling,
granting any participation in, or otherwise distributing the
Securities.  By executing this Agreement, Lender further
represents that Lender does not have any contract, undertaking,
agreement or arrangement with any person to sell, transfer, or
grant participation to such person or any third party with
respect to any of the Securities.

               (c)  Disclosure of Information.  Lender believes
it has received all the information it considers necessary or
appropriate for deciding whether to enter into this Agreement and
acquire the Convertible Note.  Lender further represents that it
has had an opportunity to ask questions and receive answers from
USMX regarding the terms and conditions of the Convertible Note
and the business, properties, prospects and financial condition
of USMX.

               (d)  Investment Experience.  Lender is an investor
in securities of companies which can be considered speculative in
nature and acknowledges that it is able to fend for itself, can
bear the economic risk of its investment, and has such knowledge
and experience in financial and business matters that it is
capable of evaluating the merits and risks of the investment in
the Securities.

               (e)  Restricted Securities.  Lender understands
that the Securities it is purchasing are characterized as
"restricted securities" under the federal securities laws

<PAGE>

inasmuch as they are being acquired from USMX in a transaction
not involving a public offering and that under such laws and
applicable regulations, such securities may be resold without
registration under the Securities Act of 1933, as amended, only
in certain limited circumstances.


                           ARTICLE 7

discretion), perform all covenants in this Article 7.

account of, and visit the properties of, USMX and to discuss the
affairs, finances and accounts of USMX with any of its officers,
directors, employees or agents.  USMX will not be responsible for
injuries to or damages suffered by agents or representatives of

reasonable costs thereof.

          7.4  Maintenance of Insurance.  USMX shall maintain,
with respect to its assets and its business generally (or, with
respect to the Mining Properties, cause AK to maintain),
insurance with responsible and reputable insurance companies or
associations in such amounts and covering such risks as is
prudent and consistent with good operating practices, with such
insurance listed in Schedule 7.4.  All such insurance shall name
Lender as an additional insured or loss payee, as the case may
be, and shall contain an endorsement providing that such
insurance cannot be terminated without at least ten days' prior
notice to Lender.

          7.5  Keeping of Records and Books of Account.  USMX

complete entries shall be made in accordance with GAAP
consistently applied, reflecting all financial transactions of
USMX.

          7.6  Preservation of Existence, Etc.  USMX shall
preserve and maintain, and shall cause AK to preserve and
maintain, its corporate existence, rights, franchises and
privileges in the jurisdiction of its incorporation, and will,
and will cause AK to, qualify and remain qualified as a foreign
corporation in each jurisdiction in which such qualification is
necessary or desirable in view of its business and operations or
the ownership of its properties.  USMX will comply with all
requirements of applicable law and all rules, regulations and
requirements of stock exchanges on which the Common Stock is
traded concerning disclosure of matters relevant to USMX and its
properties, and will timely file full and complete reports
concerning its business and operations as required by such laws,
rules, regulations and requirements.

          7.7  Conduct of Business.  USMX shall engage
principally in the business of exploring for, developing and

in accordance with generally accepted industry practices.  USMX
shall cause AK to comply with all of its obligations, agreements
and covenants under the AK Credit Agreement and documents and
other Instruments entered into by AK pursuant thereto.

          7.8  Notice of Default.  USMX shall furnish to Lender
as soon as possible and in any event within five Business Days
after the occurrence of each Event of Default or each event or
condition which with the giving of notice or lapse of time, or
both, would constitute an Event of Default, continuing on the
date of such statement, a statement of the president or chief
financial officer of USMX setting forth the details of such Event
of Default or event or condition, and the action which USMX

<PAGE>

proposes to take with respect thereto.

          7.9  Defense of Title.  USMX shall, or shall cause AK
to, defend, at its expense, title to the Mining Properties, as
such title is represented and warranted in Section 6.1(i), and
the Liens in favor of Lender under the Security Documents, and
maintain and preserve such Liens as first Liens upon the
properties and interests subject to the Security Documents,
subject only to Permitted Liens.

          7.10 Operations.  USMX agrees to use, or cause AK to
use, all commercially reasonable efforts to maintain, develop and
operate the Illinois Creek Gold Property in accordance with
prudent mining industry practices, the Feasibility Study and the
Development Plan.

          7.11 Maintenance of the Mining Properties.  USMX agrees
to maintain, and cause AK to maintain, its property rights and
interests in the Mining Properties in full force and effect, and
to do all acts reasonably determined by USMX to be necessary to
preserve such rights and interests, including, by way of example
and not limitation, payment and performance of all terms of
leases pertaining to such rights and interests, and timely
performance of work reasonably intended to satisfy any annual
assessment work requirements for unpatented mining or millsite
claims included in such properties, or timely payment of
appropriate sums in lieu of performance of assessment work, and
timely filing of federal, provincial and state notices with
respect thereto; provided, however, that USMX or AK may, in the
ordinary course of its and AK's business, abandon unpatented
mining or millsite claims and/or leased properties which USMX
does not believe warrant further maintenance expenditures.

                           ARTICLE 9

                       CONVERSION RIGHTS

          9.1  Lender's Loan Conversion Rights.  At any time
after the date of the Advance while the Loan remains outstanding
and unpaid, Lender may by notice to USMX and at any time that the
Principal Amount remains outstanding, elect to convert all or any
part of the Principal Amount into all or any portion of the
Conversion Shares in accordance with the provisions of this
Article 9.  Upon such conversion, the Principal Amount of the
Loan shall be deemed to have been paid in full.

          9.2  USMX's Loan Conversion Rights.  Upon the
satisfaction of the Conditions Precedent to USMX's Conversion
Rights and while such conditions remain satisfied, USMX may for a
period of five (5) Trading Days beginning on the first Trading
Day after the Conditions Precedent to USMX's Conversion Rights
are first satisfied, by notice to Lender, elect to convert the
Loan into the Conversion Shares in accordance with the provisions
of this Article 9.  Upon any such conversion, the Principal
Amount of the Loan will be deemed to have been paid in full.
Failure of USMX to provide Lender with notice herein required
within the five (5) Trading Day period specified in this Section
9.2 shall terminate any right USMX has to require Lender to
convert the Loan into shares of Common Stock.

          9.3  Loan Conversion Procedures.

               (a)  Conversion Date.  The Conversion Date will be
the fifth Business Day following the date of exercise by either
Lender or USMX of its Conversion Right.

               (b)  Conversion Procedures.  Not later than the
Conversion Date, USMX will have taken all actions, including
filing reports required by Governmental Authorities or with stock
exchanges on which the Common Stock is traded and preparation of
a certificate or certificates for the Common Stock to be issued
upon conversion in the denominations requested by Lender, as are
necessary to enable USMX to deliver to Lender on the Conversion
Date the certificates for the Conversion Shares.  Whether or not
USMX delivers such certificates on the Conversion Date, Lender
will be deemed to be the owner of the Conversion Shares as of the
Conversion Date, with all voting rights, rights to receive
dividends and distributions and all other rights associated with
ownership of the Conversion Shares.  Upon delivery of
certificates for such Common Stock, Lender will deliver the
Convertible Note to USMX, marked paid and endorsed by Lender or
the Holder thereof.

               (c)  Certain Agreements Regarding Conversion
Rights.

                    (i)  No fractional shares of Common Stock
will be issued upon exercise of a Conversion Right.  Instead of
any fractional share of Common Stock that would otherwise be
issuable upon such conversion, USMX will pay Lender or Holder a
cash adjustment in respect of such fraction determined by
multiplying such fraction times the Conversion Price.

<PAGE>

                    (ii) If after the date hereof USMX

                                                  A.   pays a
                              dividend or makes a distribution on
                              the Common Stock in shares of
                              Common Stock;

                                                  B.   subdivides
                              the shares of Common Stock
                              outstanding on the date hereof into
                              a greater number of shares of
                              Common Stock;

                                                  C.
                              consolidates the number of shares
                              of Common Stock outstanding on the
                              date hereof into a smaller number
                              of shares of Common Stock; or

                                                  D.   issues any
                              shares of Common Stock by reason of
                              any reclassification of shares;

the Conversion Price in effect immediately prior thereto shall be
adjusted so that Lender will, upon exercise of the Conversion
Rights be entitled to receive the number of shares of Common
Stock which Lender would have owned or have been entitled to
receive after the happening of any of the events described above
in this clause (ii) had the Loan been converted immediately prior
to the happening of such event.  An adjustment made pursuant to
this clause (ii) shall become effective immediately after the
close of business on the record date in the case of a dividend or
distribution and shall become effective immediately after the
close of business on the record date in the case of a
subdivision, consolidation or reclassification.

                       (iii)  If after the date hereof USMX shall
issue rights or warrants entitling any Persons to subscribe for,
purchase or otherwise receive Common Stock to be issued by USMX
at a price less than the Daily Closing Price on the Trading Day
preceding the date of issuance of such rights or warrants, then
the Conversion Price in effect immediately prior thereto shall be
adjusted to equal an amount determined by multiplying (I) the
Conversion Price in effect immediately prior to the date of
issuance of such rights or warrants by (II) a fraction, the
numerator of which shall be the sum of (w) the number of shares
of Common Stock outstanding on the date of issuance of such
rights or warrants (without giving effect to shares of Common
Stock which may be issued upon exercise thereof) and (x) the
number of shares of Common Stock which the consideration received
or to be received by USMX in connection with issuance and
exercise of such rights or warrants would purchase at such Daily
Closing Price; and the denominator of which shall be the sum of
(y) the number of shares of Common Stock determined in (w) above
and (z) the number of shares of Common Stock issued or issuable
upon exercise of such rights or warrants in accordance with the
terms thereof.

<PAGE>

          9.4  Lender's Registration Rights Upon Loan Conversion.
USMX shall execute and deliver herewith the Registration Rights
Agreement in the form of Exhibit D providing for the registration
of the Conversion Shares as freely tradable shares of stock
pursuant to applicable federal and state securities laws.

observe or perform any of their respective covenants,
undertakings or agreements contained in this Agreement, the AK
Credit Agreement or any other Loan Document other than the
covenants referred to in paragraph (a) above, and USMX or AK has
not remedied such default within ten days after notice of default
has been given by Lender to USMX or AK, as the case may be.

                (c)  Representation or Warranty.  Any representa
tion or warranty made by USMX or AK (or any of their officers)
under or in connection with this Agreement, the AK Credit
Agreement and related agreements and Instruments, or the other
Loan Documents shall prove to have been incorrect in any material
respect when made.

                (d)  Cross-Default.  A default shall occur under
the AK Credit Agreement or related agreements and Instruments,
any of the other Loan Documents, or under any agreement
pertaining to Indebtedness permitted by Section 8.1, or USMX or
AK shall fail to pay any Indebtedness in excess of $100,000 in
principal amount (but excluding Indebtedness evidenced by the
Convertible Note and the Pledged Notes), or any interest or
premium thereon, when due (whether by scheduled maturity,
required prepayment, acceleration, demand or otherwise) and such
failure to pay is not being contested by USMX or AK, as
appropriate, in good faith; or any other default under any
agreement or instrument relating to any such Indebtedness or any
other event, shall occur and shall continue after the applicable
grace period, if any, specified in such agreement or instrument,
if the effect of such default or event is to accelerate, or to
permit the acceleration of, the maturity of such Indebtedness,
unless such default or event shall be waived by the holders or
trustees for such Indebtedness; or any such Indebtedness shall be
declared to be due and payable, or required to be prepaid (other
than by a regularly scheduled required prepayment), prior to the
stated maturity thereof.

                (e)  Insolvency.  Either USMX or AK shall

<PAGE>                
                
generally not pay its debts as such debts become due, or shall
admit in writing its inability to pay its debts generally, or
shall make a general assignment for the benefit of creditors; or
any proceeding shall be instituted by or against USMX or AK
seeking to adjudicate it a bankrupt or insolvent, or seeking a

against USMX or AK and either (i) enforcement proceedings shall
have been commenced by any creditor upon such judgment or order
or (ii) a stay of enforcement of such judgment or order, by
reason of a pending appeal or otherwise, shall not be in effect
for any period of ten consecutive days.

                (g)  Security Interest.  Any of the Security
Documents or Instruments creating security interests delivered by
USMX or AK pursuant to the AK Credit Agreement, after delivery
thereof shall for any reason, except to the extent permitted by
the terms thereof, cease to create a valid and perfected security
interest with the priority required by this Credit Agreement or
the AK Credit Agreement in any of the Collateral purported to be
covered thereby, or USMX or AK shall so state in writing.

                (h)  Condemnation.  Any of the interests of USMX
or AK in the Mining Properties is taken by power of expropriation
or eminent domain or sold under threat of such taking, or
possession of any portion of the lands necessary for the
operation of the Project is taken through exercise of such power,
and such taking, loss or sale has or could have a Material
Adverse Effect on the Project, as determined by the Lender in its
sole discretion reasonably exercised.

                (i)  Regulatory Action.  Any Governmental
Authority shall take any action with respect to USMX, AK or the
Project or any other Collateral subject to the Security Documents
which would have a Material Adverse Effect on USMX, AK,
operations on the Project or USMX's ability to repay the Loan
unless such action is set aside, dismissed or withdrawn within 90
days of its institution or such action is being contested in good
faith and its effect is stayed during such contest.

or the Board of Directors of USMX or AK elects not to proceed
with the Project for whatever reason;

                     (ii) An Illinois Creek Loan Acceleration

25% working interest in the Project and NPMC has not become a
party to this Agreement and the Loan Documents, and executed and
delivered such other agreements and Instruments as Lender, in its
sole discretion, deems necessary or desirable in order to

this Agreement and the Loan Documents;

                     (iv) USMX breaches any agreement, covenant
or undertaking under the NPMC Agreement which is not waived or
cured within the applicable grace period, including without
limitation, its obligation to register as provided by the NPMC

                (k)  Default Under Hedging Contract.  Any
condition or event or combination thereof exists under a Hedging
Contract which, of itself, or, with notice or the passage of

or give rise to remedies of the other party of acceleration of
time of performance by USMX or AK of its obligations thereunder.

                (a)  Upon the occurrence of an Event of Default
specified in Section 10.1(e) of this Agreement or, in the case of
any other Event of Default, upon notice by Lender to USMX of
Lender's election to declare USMX in default, the obligations of
Lender hereunder including, without limitation, Lender's
obligation to Advance the Loan, shall terminate.  The date on
which such notice is sent or, in the case of an Event of Default
specified in Section 10.1(e) of this Agreement, the date of such
Event of Default, shall be the "Date of Default."

                (b)  Upon the Date of Default, upon notice
thereof from Lender to USMX in all cases other than the
occurrence of an Event of Default as specified in
Section 10.1(e), the Loan, all interest thereon, Breakage Costs
and all other amounts owed by USMX hereunder shall be immediately
due and payable in full.  In the case of an Event of Default
specified in Section 10.1(e), no notice from Lender shall be
required, and all amounts owed by USMX hereunder shall be
immediately due and payable on the Date of Default, without
notice from Lender.

                (c)  Upon the occurrence of an Event of Default,
all of the remedies provided to Lender in all of the Security
Documents shall immediately become available to Lender.

                (d)  Except as expressly provided above in this
Section 10.2, presentment, demand, protest and all other notices
of any kind are hereby expressly waived.  From and after the Date

phrases, clauses, sentences or paragraphs had not been inserted.

unless such information is known, or until such information
becomes known, to the public; provided, however, that Lender may
disclose such information to its attorneys, accountants,
consultants and other professionals in connection with the
provision of professional services to the Lender.

               (c)  Payment of Fees.  Payment of the Establishment Fee and
Commitment Fees shall be made in Dollars by wire transfer to Lender's
account as specified in Section 3.11.


                           ARTICLE 3

                     PROCEDURE AND PAYMENT

          3.1  Advance Procedure.

               (a)  Requests for Loans.  No more frequently than once
during any 30-day period, and not less than two Business Days prior to the
desired date of the Advance of a Loan, Borrower will submit a Request for
Advance to Lender.  The Request for Advance, which will be effective only
upon actual receipt by Lender, will specify whether a Gold Loan or a Dollar
Loan is requested.  Each Request for Advance shall be irrevocable when it
becomes effective upon receipt by Lender.

               (b)  Gold Loan.  A Gold Loan shall be Advanced only in a
single Advance for the Maximum Credit Amount, and only if no Dollar Loans
are outstanding.  The Request for Advance will specify an initial Interest
Period for the Gold Loan and the Business Day on which Borrower wishes to
have the Advance made.  The number of Ounces of Gold Advanced shall be
equal to the result of the Maximum Credit Amount divided by the London
Price two (2) Business Days prior to the date of Advance of the Gold Loan,
and such price per Ounce of Gold shall be the "Original Gold Price".
Lender shall sell such number of Ounces of Gold at the Original Gold Price
and shall deposit the proceeds thereof by wire transfer in the Proceeds
Account.

               (c)  Dollar Loans.  If a Dollar Loan is requested, the
Request for Advance will specify the amount of the Advance in Dollars, an
initial Interest Period for the Advance and the Business Day on which
Borrower wishes to have the Advance made.  On the date specified in the
Request for Advance, Lender shall wire transfer each Advance to the
Proceeds Account.

          3.2  Notes.  A Gold Loan shall be evidenced by the Gold Note and
Dollar Loans shall be evidenced by the Dollar Note.

<PAGE>

          3.3  Loan Conversion Elections.

               (a)  Conversion.  Subject to the terms and conditions
hereof, Borrower is hereby granted the right to elect to convert an
outstanding Gold Loan to a Dollar Loan, or all (but not part) of the
outstanding Dollar Loans to a Gold Loan, from time to time after the
Advance Period and prior to the Scheduled Maturity Date, (i) only if Lender
is able to provide the requested type of Loan; (ii) only if no Default
exists or would be caused by such conversion; (iii) only if the Scheduled
Maturity Date has not been accelerated by Lender; (iv) in the case of
outstanding Dollar Loan to be converted to a Gold Loan, only if the London
Price is above the Minimum Gold Price; (v) only concurrently with the end
of the Interest Period applicable to the Loans; (vi) only if modifications
to hedging arrangements of Borrower satisfying the requirements of
Section 8.12 are taken simultaneously with such conversion; and (vii) only
on a Business Day.  Each such election shall be effected by Borrower's
delivery to Lender of a Conversion/Interest Period Notice and shall be
effective three Business Days after receipt by Lender of such notice.
Notwithstanding the foregoing, the Borrower may not request that more than
one conversion of Loans from one type to another type thereof be effected
during any twelve (12) month period.

          For purposes of effecting any such conversion, the equivalency
calculations shall be made by Lender on the effective date of such
conversion.  Subject to other relevant provisions of this Agreement,
Borrower shall make a repayment in full of the relevant type and Principal
Amount of the Loans to be converted and the Lender shall make Loans of the
relevant type and Principal Amounts of Loans which are to be outstanding
immediately following such conversion.  A Gold Loan will be converted to a
Dollar Loan by multiplying the Principal Amount of the Gold Loan in Ounces
of Gold by the Original Dollar Value thereof, with the resultant Dollar
amount being the Principal Amount of the Dollar Loan into which such Gold
Loan will convert.  Dollar Loans will be converted to a Gold Loan by
dividing the Principal Amount of the Dollar Loans by the London Price in
effect on a date two (2) Business Days prior to the date of conversion,
with the resultant amount being the Ounces of Gold comprising the Principal
Amount of the Gold Loan into which such Gold Loan shall convert.

          3.4  Principal and Interest Payments Generally.  All principal
and interest payments of a Gold Loan shall be made in Gold.  All principal
and interest payments of Dollar Loans shall be made in Dollars.  If a
conversion of a Loan occurs during an Interest Period pursuant to
Section 3.9, interest will be payable through the date of conversion in the
form of the Loan prior to conversion and after the date of conversion in
the form of the Loan after conversion.

<PAGE>

          3.5  Interest.

               (a)  General.  Borrower shall pay interest on the
outstanding Principal Amount of Loans calculated on a 360-day year basis,
at the Gold Loan Interest Rate if a Loan is a Gold Loan or at the Dollar
Loan Interest Rate if Loans are Dollar Loans or at the Default Rate, as
applicable.  Interest payable shall be calculated daily.  Interest
calculated at the Gold Loan Interest Rate or at the Dollar Loan Interest
Rate shall be payable either quarterly in arrears on the first Business Day
of each quarter with respect to the preceding quarter or, in the case of an
Interest Period which ends within a quarter, in arrears at the end of such
Interest Period.  Interest calculated at the Default Rate shall be payable
on demand.

               (b)  Interest Periods.  Borrower may select an interest
period with respect to each Advance ("Interest Period") of 30, 90 or
180 days, or of such other period of days as may be agreed to by Lender in
its sole discretion, on a 360-day year basis; provided that in no event may
more than three (3) different Interest Periods be in effect hereunder at
any one time.  Borrower will select Interest Periods by giving notice to
Lender in the Request for Advance and thereafter at least three (3)
Business Days prior to the expiration of the Interest Period then in effect
by a Conversion/Interest Period Notice.  If at any time Borrower fails to
give timely notice of its Interest Period selection, then Borrower shall be
deemed to have selected an Interest Period of thirty (30) days.  No
Interest Period shall end after the Scheduled Maturity Date.

               (c)  Default Interest.  Interest on the Loans shall accrue
and shall be payable by Borrower at the Default Rate during all periods
when any amounts payable by Borrower as principal repayments, interest
payments or fee or expense payments are due and payable hereunder, whether
by acceleration or otherwise, but remain unpaid by Borrower; provided the
Default Rate shall not apply to past-due fees and expenses unless Lender
has provided written notice to Borrower pursuant to Section 11.2, and such
fees and expenses remain due and unpaid for five (5) Business Days after
the giving of such notice.  Without prejudice to the rights of Lender under
the preceding sentence, Borrower shall indemnify Lender against any direct
loss or expense (not including lost profits on re-employment of capital)
which Lender may sustain or incur as a result of the failure by Borrower to
pay when due the Principal Amount of the Loans.  A certificate or other
notice of Lender submitted to Borrower setting forth the basis for the
determination of Default Rate interest due and of the amounts necessary to
indemnify Lender in respect of such loss or expense, shall constitute
evidence of the accuracy of the information contained therein in the
absence of error and, absent notice from Borrower of such error, shall be
conclusive and binding for all purposes.  Interest accruing at the Default
Rate shall be payable on demand.

          3.6  Repayment of the Loans.

               (a)  Principal Repayment Generally.  Borrower agrees to
repay the Loans as provided herein.  Loan amounts repaid may not be
reborrowed.

               (b)  Scheduled Principal Payments.  Subject to the other
terms hereof pertaining to mandatory prepayments of the Loans, Borrower
shall repay the Principal Amount of the Loans in the amounts and on the
dates set forth in the amortization schedule attached hereto as

<PAGE>

Schedule 3.6(b), with each payment equal to an amount determined by
multiplying the Principal Amount as of July 31, 1997 by the percentage
stated in the amortization schedule for the corresponding payment date,
subject to adjustment for any voluntary prepayments pursuant to
Section 3.6(c) and mandatory prepayments pursuant to Sections 3.6(d)
and 3.6(e).

               (c)  Voluntary Prepayment.  Upon not less than thirty
(30) days' prior written notice to Lender, Borrower may, without premium or
penalty, prepay at the end of any Interest Period applicable to the portion
of the Loan so prepaid, in the case of a Dollar Loan, One Million Dollars
($1,000,000) or larger portion of the Principal Amount of Dollar Loans, or
in the case of a Gold Loan, a number of Ounces of Gold that when multiplied
by the Original Gold Price results in a Dollar Value that is greater than or
equal to One Million Dollars ($1,000,000).  Upon the giving of such notice,
which shall be irrevocable, the prepayment, together with all interest
accrued through the prepayment date, shall be due and payable on the date
set forth therein.  Any such voluntary prepayment of the Loans shall be
applied to the outstanding Principal Amount, and shall be applied to the
scheduled principal payments of the Loan provided for in Section 3.6(b) in
inverse order of maturity.

               (d)  Mandatory Prepayment Upon Loan Acceleration.  Borrower
will repay the Principal Amount of Loans in full, together with accrued
interest thereon, Breakage Costs and fees, upon acceleration of the due
date thereof by Lender pursuant to Section 10.2

               (e)  Mandatory Prepayments Where a Gold Loan Principal
Amount Exceeds Monetary Cap.  If at any time the Dollar Value of a Gold
Loan exceeds the Monetary Cap, within not more than three (3) Business Days
after notice thereof by Lender, Borrower will prepay a portion of the
Principal Amount of the Gold Loan which is sufficient to reduce the Dollar
Value of the Gold Loan to an amount which is less than the Monetary Cap.

          3.7  Priority of Prepayments.  All Loan prepayments made by
Borrower pursuant to Sections 3.6(d) and (e) shall be accompanied by
payment of Lender's Breakage Costs, if any, and shall be applied first to
accrued and unpaid interest on the Loans so prepaid as of the end of the
most recent Interest Period, then to any other amounts then payable by
Borrower hereunder including Breakage Costs and fees, then to the Principal
Amount in inverse order of maturity thereof.

          3.8  Risk of Loss.  Borrower will assume all risk of loss of, or
damage to, any Gold to be delivered by it to Lender hereunder until it has
been delivered to Lender at an Acceptable Delivery Location.  Unless
Borrower has received notice of error within fourteen (14) Business Days of
Lender's receipt of Gold so delivered, Lender's receipt of the quantity and
quality of the Gold will be conclusively deemed to be as set out in
Borrower's delivery order.

          3.9  Inability to Continue to Provide Gold; Mandatory Switching.
Lender shall not be liable for any failure to comply with its obligations
under or pursuant to this Article 3, and shall be entitled to terminate any
arrangements entered into under this Article without liability, if such
failure is caused directly or indirectly, wholly or partly, by act or
omission of any government or competent authority, lack of availability of
Gold, force majeure or other contingency, circumstance or event of any
nature beyond the control of Lender.  Notwithstanding any other provision
hereof, a Gold Loan will be converted to Dollar Loans upon any such event
effective as of the date Lender gives Borrower notice of the foregoing.

<PAGE>

          3.10 Increased Costs and Reduction in Return.  If due to (a) the
introduction of, or any change (including, without limitation, any change
by way of imposition or increase of reserve requirements) in, or in the
interpretation of, any law or regulation or (b) the compliance by Lender
with any guideline or request from any central bank or other governmental
agency having jurisdiction over Lender (whether or not having the force of
law) collectively referred to as "Governmental Acts," there shall be any
increase in the cost or reduction in return to Lender of agreeing to make
or making, funding or maintaining the Loan, then Borrower shall from time
to time, upon demand by Lender, pay to Lender additional amounts sufficient
to indemnify it against such increased costs or reduction in return;
provided that Lender agrees to use reasonable efforts to mitigate the
increased cost or reduction in return to the extent reasonably practicable.
A certificate as to the amount of such increased cost or reduced return,
submitted to Borrower by Lender, shall be conclusive absent manifest error.

          3.11 Payments and Computations.  Borrower shall make each payment
due in Gold hereunder and under the Note not later than 5:00 p.m. (New York
City time) on the day before the day when due.  Borrower shall make each
payment due in Dollars hereunder and under the Note in immediately
available funds not later than 5:00 p.m. (New York City time) on the day
before the day when due Lender as follows (or as Lender shall otherwise
advise Borrower by notice as provided herein):

          to:

               Chase Manhattan Bank N.A.
               1 Chase Manhattan Plaza
               New York, New York
               ABA No. 02100021

                    for the account of N M Rothschild & Sons Limited
                    A/C No.:  001-1-948262

Payments in Gold shall be made by delivery of Gold to the account of Lender
at any Acceptable Delivery Location.  Borrower agrees to pay all shipping,
insurance, refining charges and other costs related to such delivery and
warrants that such Gold upon its delivery to the account of Lender shall be
free and clear of all Liens, encumbrances, charges and security interests
except those in favor of Lender.  Borrower hereby authorizes Lender, if and
to the extent payment of money owed to it is not made when due hereunder or
under the Note, to charge from time to time against Borrower's accounts
with Lender any amount so due.  All computations of interest hereunder
shall be made on the basis of a year of 360 days for the actual number of
days elapsed (including the first day but excluding the last day).

          3.12 Payment on Non-Business Days.  Whenever any payments of Gold
or Dollars to be made hereunder or under the Note shall be due on a day
which is not a Business Day, such return or payment may be made on the next
succeeding Business Day, and such extension of time shall in such case be
included in the computation of payment of interest or fees, as the case may
be, unless such next succeeding Business Day is after the end of the

<PAGE>

Interest Period, in which case the payment will be made on the next
preceding Business Day and such payment shall not reflect the actual
payment date in the computation of interest or fees due and payable.

          3.13 Taxes.

               (a)  General.  Any and all payments by Borrower hereunder
shall be made free and clear of and without deduction for any and all
present or future taxes, levies, duties, imposts, deductions, charges or
withholdings, and all liabilities with respect thereto (excluding taxes
imposed on Lender's income and franchise taxes imposed on Lender) imposed
by the jurisdiction under the laws of which Lender is organized, or the
United States of America, the state of Alaska or any other jurisdiction
under the laws of which Lender is otherwise subject to tax, or any
political subdivision thereof (all such non-excluded taxes, levies, duties,
imposts, deductions, charges, withholdings and liabilities being
hereinafter referred to as "Taxes").  If Borrower shall be required by law
to deduct any Taxes from or in respect of any sum payable hereunder to
Lender, (i) the sum payable shall be increased as may be necessary so that
after making all required deductions (including deductions applicable to
additional sums payable under this Section 3.13) Lender receives an amount
equal to the sum it would have received had no such deductions been made,
(ii) Borrower shall make such deductions and (iii) Borrower shall pay the
full amount deducted to the relevant taxation authority or other authority
in accordance with applicable law.  The foregoing obligation of Borrower
will apply with respect to any assignee of Lender.

               (b)  Other Taxes.  In addition, Borrower agrees to pay any
present or future stamp, sales, use or documentary taxes or any other
excise or property taxes, charges, duties or similar levies which arise
from any payment made hereunder or from the execution, delivery or
registration of, or otherwise with respect to, this Agreement, any of the
Loan Documents, or any Instrument contemplated thereby (hereinafter
referred to as "Other Taxes").  To Lender's knowledge, no Other Taxes will
be applicable to the transactions contemplated by this Agreement.

               (c)  Tax Indemnity.  Borrower hereby indemnifies Lender for
the full amount of Taxes and Other Taxes (including, without limitation,
any Taxes or Other Taxes imposed by any jurisdiction on amounts payable
under this Section 3.13) paid by Lender and any liability (including
penalties, interest and expenses) arising therefrom or with respect
thereto.  Lender shall use commercially reasonable efforts to mitigate any
Taxes or Other Taxes to the extent practicable, and to refund to Borrower
its proportionate share of any Taxes or Other Taxes paid by Borrower
pursuant hereto ultimately refunded to Lender.

               (d)  Payment of Taxes.  Within 30 days after the date of any
payment of Taxes or Other Taxes withheld by Borrower in respect of any
payment to Lender, Borrower will furnish to Lender the original or a
certified copy of a receipt evidencing payment thereof.

               (e)  Lender's Taxes.  To Lender's knowledge, under
applicable law and treaties in effect as of the date hereof between the
United States and the United Kingdom, no United States federal taxes will
be required to be withheld by Borrower with respect to any payment to be
made to Lender in respect of this Agreement.  Lender agrees upon written
request of Borrower to deliver to Borrower, in duplicate, duly completed
and signed copies of either Form 1001 (relating to Lender and entitling
Lender to a complete exemption from withholding on all amounts to be

<PAGE>

received by Lender pursuant to this Agreement, the Loans and Notes as a
result of a tax treaty concluded with the United States) or Form 4224
(relating to all amounts to be received by Lender pursuant to this
Agreement, the Loans and Notes) of the Internal Revenue Service.

               (f)  Survival.  Without prejudice to the survival of any
other agreement hereunder, the agreements and obligations contained in this
Section 3.13 shall survive the payment in full of the Loan and interest
hereunder.

          3.14 Proceeds Account.

               (a)  Prior to the Initial Advance of the Loans, Borrower
will execute and deliver the Proceeds Account Agreement, will establish an
account with a national banking institution, satisfactory to Lender in its
sole discretion reasonably exercised (the "Proceeds Account"), will enter
into an escrow agreement with such banking institution in form acceptable
to Lender and will at all times upon and after Completion while any portion
of the Loans remains outstanding maintain a balance in the Proceeds Account
at least equal to the Retention Amount.  Borrower will promptly deposit all
gross revenues of, and all other payments received in relation to, the
Project including the proceeds of Dollar Loans, the Dollar equivalent
(calculated on the date of making of any Gold Loan as set forth in
Section 3.1) of the proceeds of such Gold Loan, the proceeds derived from
the exercise of any Hedging Contract, the net proceeds of any equity or
debt offering by Borrower to any Person, including USMX or a Subsidiary of
USMX, all funds received from USMX (whether as loans or equity
contributions), the net proceeds of any disposition of Project Assets and
any insurance proceeds received in connection with the Project to, and
shall disburse all funds, including funds disbursed for Project Costs from,
such account.

          Disbursements or withdrawals from the Proceeds Account will be
made by Borrower only pursuant to a Request for Disbursement in the form of
Exhibit B hereto.

          Credit balances in the Proceeds Account shall be applied as
follows:

          First, to payment of Project Capital Costs and Project Operating
          Costs, incurred by Borrower in accordance with the Development
          Plan;

          Second, to payment of fees or other amounts due Lender hereunder
          or under any of the Loan Documents which are due and payable and
          which remain unpaid;

          Third, to payment of interest and the Principal Amount due and
          payable hereunder, and principal and interest payments of the
          $2,500,000 USMX Secured Loan; and

          Fourth, after Completion and provided that no Default or Event of
          Default is outstanding hereunder, Borrower may, on a quarterly
          basis, withdraw funds for general corporate purposes, including
          permitted dividends to stockholders, so long as after any such
          withdrawal the Proceeds Account contains an amount greater than
          or equal to the Retention Amount.

               (b)  On each principal repayment date referred to in

<PAGE>               
               
Section 3.6(b), and on any other due date of any portion of the Loans, Loan
repayments shall (without prejudice to the right of Lender to such
repayment of any Obligation from any other source) be made (i) in the case
of Dollar Loans in Dollars by payment to Lender of an amount sufficient to
provide for such repayment or prepayment, or (ii) in the case of a Gold
Loan, in Ounces of Gold by payment to Lender or any other member of The
London Bullion Market Association reasonably acceptable to Lender a Dollar
amount sufficient to provide for such repayment or prepayment in Ounces of
Gold with irrevocable instructions to transfer such Ounces of Gold to an
Acceptable Delivery Location.

               (c)  Borrower hereby pledges, assigns and grants to Lender a
security interest in the Proceeds Account and all funds in the Proceeds
Account from time to time, in accordance with common law pledge
requirements and the Uniform Commercial Code.  Upon occurrence of a Default
or Event of Default, Borrower agrees that, notwithstanding the provisions
of clause (a) above concerning application of funds in the Proceeds
Account, Lender may elect not to honor a Request for Disbursement received
from Borrower; Lender may prohibit any withdrawals or transfers of funds by
Borrower or by any Persons claiming interests by, through or under Borrower
(and for this purpose  shall return marked "NSF" any checks or other
instruments or orders for payment of money received by Lender); and Lender
shall be entitled to exercise its rights hereunder with respect to all
funds in the Proceeds Account in accordance with law, including, without
limitation, transfer of such funds to Lender in payment or partial payment
of Borrower's Obligations.  In connection therewith, Borrower agrees and
covenants to indemnify Lender against any claim, cost or liability incurred
by Lender in connection with its refusal, as permitted herein, to honor a
Request for Disbursement received from Borrower or in connection with its
application of funds in the Proceeds Account, as permitted herein, in
satisfaction of Borrower's Obligations.


                           ARTICLE 4

                        HEDGING FACILITY

          4.1  Establishment of Hedging Facility.  Concurrently herewith,
Lender has established a Gold hedging facility in favor of Borrower on the
terms and conditions of the Hedging Agreement.


                           ARTICLE 5

                      COLLATERAL SECURITY

          5.1  Security Documents.  As security for the due repayment of
Loans hereunder, for the payment of all moneys due hereunder, for the
performance of all Obligations of Borrower and USMX hereunder and under the
other Loan Documents, Borrower shall contemporaneously with the execution
of this Agreement, execute and deliver to Lender the Security Documents to
which it is a party, including amendments or assignments thereof and
notices to third Persons as Lender may require in connection with the
perfection of its security interests in the property and interests subject
to the Security Documents.

          5.2  No Limitation on Application of Security Interests.

<PAGE>          
          
Borrower and Lender agree that notwithstanding any provision of any
Security Document to the contrary, all Liens created and perfected pursuant
to the Security Documents shall secure all Obligations of Borrower
hereunder and under the other Loan Documents.

          5.3  Recordings and Filings of Security Documents.  Lender will
record, file or deliver to account debtors as necessary the Security
Documents, as appropriate, at Borrower's expense, promptly after execution
and delivery thereof by Borrower.

          5.4  Protection of Security Document Liens.  As and when
requested to do so by Lender, Borrower will deliver to Lender from time to
time any financing statements, continuation statements, extension
agreements and other documents, properly completed and executed (and
acknowledged when required) by Borrower in form and substance satisfactory
to Lender, for the purpose of perfecting or protecting Lender's Liens on
the property and interests subject to the Security Documents.

          5.5  Right of Set-off.  Upon the occurrence and during the
continuance of any Event of Default, Lender is hereby authorized at any
time and from time to time, without notice to Borrower or USMX (any such
notice being expressly waived by Borrower), to set off and apply any and
all deposits (general or special, time or demand, provisional or final) at
any time held and other indebtedness at any time owing by Lender to or for
the credit or the account of Borrower against any and all of the
Obligations of Borrower now or hereafter existing, although such
Obligations may be contingent and unmatured.  Lender agrees promptly to
notify Borrower after any such set-off and application, provided that the
failure to give such notice shall not affect the validity of such set-off
and application.  The rights of Lender under this Section 5.5 are in
addition to other rights and remedies (including, without limitation, other
rights of set-off) which Lender may have.

          5.6  Additional Collateral.  Borrower and Lender intend that the
Security Documents cover and extend to all property rights and interests of
Borrower, real or personal, tangible or intangible, presently held or
hereafter acquired, which are related to the Project, the production
therefrom, Hedging Contracts related to the Project and the proceeds of all
of the foregoing.  In the event that Borrower acquires any property right
or interest related to the Project which is not subject to the Lien of the
Security Documents, upon request therefor from Lender, Borrower shall
promptly execute and deliver such Instruments and take such actions as
Lender may reasonably request in order to perfect a first and prior Lien on
such right or interest, subject only to Permitted Liens with the priority
expressly provided hereunder or under the USMX Credit Agreement.  Whether
or not Lender requests that any such right or interest be subjected to the
Security Documents, Borrower agrees to keep such rights or interests
related to the Project free and clear of all Liens other than Permitted
Liens.

          5.7  Partial Release of USMX Upon Completion of the Project.
Upon Completion, if no Default or Event of Default is outstanding, Lender's
recourse with respect to the obligations of USMX under the Guaranty will be
limited to the Pledged Collateral pursuant to the Pledge Agreement, as
those latter two terms are defined in the Pledge Agreement and the USMX
Credit Agreement, respectively, and the Assignment Agreement; provided that
the obligations of USMX under the Guaranty with respect to Obligations of
Borrower which arise under a breach of the representation in Section 7.1(t)
or the covenants in Section 8.1 insofar as Environmental Laws are concerned

<PAGE>

shall remain unchanged and unaffected by Completion, and shall remain the
full recourse obligation of USMX.


                           ARTICLE 6

                      CONDITIONS PRECEDENT

no more than five days prior to such date of delivery (or as otherwise
agreed by Lender), and in form and substance as shall be satisfactory to
Lender:

                    (i)  this Agreement, duly executed by Borrower;

                    (ii) the Gold Note or Dollar Note, as the case may be,

                 REPRESENTATIONS AND WARRANTIES

          7.1  Representations and Warranties of Borrower.  Borrower
represents and warrants as follows:

               (a)  Organization, Qualification and Subsidiaries.  Borrower
is a corporation duly incorporated, validly existing and in good standing
under the laws of the State of Alaska and has all requisite corporate power
and authority to enter into this Agreement and the Loan Documents to which
it is a party and to carry out the transactions contemplated hereby and
thereby.  USMX is a corporation duly incorporated, validly existing and in
good standing under the laws of the state of Delaware and has all requisite
corporate power and authority to enter into the USMX Credit Agreement, the
Loan Documents to which it is a party and to carry out the transactions
contemplated thereby.  Borrower has no subsidiaries.

               (b)  Authorization; No Conflict.  The execution, delivery
and performance by Borrower of this Agreement and of the other Loan
Documents to which it is a party have been duly authorized by all necessary
corporate action on the part of Borrower and do not and will not
(i) require any consent or approval of the stockholder of Borrower that has
not been obtained; (ii) contravene Borrower's articles of incorporation,
charter or bylaws; (iii) violate any provision of any law, rule, regulation
(including, without limitation, Regulations G, T, U and X of the Board of
Governors of the Federal Reserve System), order, writ, judgment,
injunction, decree, determination or award presently in effect having
applicability to Borrower; (iv) result in a breach of or constitute a
default under or require the consent of any party pursuant to any indenture
or loan or credit agreement or any other agreement, lease or instrument to
which Borrower is a party or by which it or its properties may be bound or
affected; or (v) result in, or require, the creation or imposition of any
Lien (other than Liens arising under the Security Documents) upon or with
respect to any of the properties now owned by Borrower; and, to the best
knowledge of Borrower, Borrower is not in breach or default in any material
respect under any such law, rule, regulation, order, writ, judgment,
injunction, decree, determination or award or any such indenture,
agreement, lease or instrument, except as otherwise disclosed to Lender in
writing prior to the date hereof.  The execution, delivery and performance
by USMX of the USMX Credit Agreement and Loan Documents to which it is a
Party has been duly authorized by all necessary corporate action and does
not and will not contravene USMX's articles of incorporation, charter or
bylaws.

               (c)  Governmental Consents; Project Permits and Authoriza

<PAGE>               
               
tions.  No authorization or approval or other action by, and no notice to
or filing with, any Governmental Authority is required (i) for the due
execution and delivery of, and due performance of the financial obligations
of Borrower under, this Agreement, any other Loan Document to which
Borrower is a party or for the due execution, delivery and performance by
the USMX of the Loan Documents to which the USMX is a party or (ii) for the
due performance of all other obligations of Borrower or USMX under this
Agreement or any other Loan Document to which Borrower or USMX is a party
(other than registrations or filings to perfect the liens created by the
Security Documents) except such authorizations, approvals or other actions
as have been obtained or notices or filings as have been made.  All
material Project Permits are identified in Schedule 7.1(c).  All Project
Permits have been duly issued to or are held by Borrower, are valid and in
good standing and free of any violation thereof by Borrower, and Borrower
has not received any notice of an asserted violation or proposed
revocation, withdrawal or material modification thereof.

               (d)  Binding Obligations.  This Agreement is, and the Loan
Documents when delivered hereunder will be, the legal, valid and binding
obligations of Borrower and USMX, respectively, enforceable against
Borrower and USMX, respectively, in accordance with their respective terms
(except as limited by applicable bankruptcy, insolvency, reorganization,
moratorium and similar laws or equitable principles affecting enforcement
of creditors' rights generally at the time in effect).

               (e)  Litigation.  Except as indicated on Schedule 7.1(e),
there is no action, proceeding or investigation pending or threatened in
writing against or involving Borrower which alleges the violation of any
laws, including Environmental Laws, or which questions the validity of this
Agreement or any of the Loan Documents, or any action taken or to be taken
pursuant to this Agreement or any of the Loan Documents, or which questions
the nature or extent of Borrower's record or equitable title to the Mining
Properties or which might result, either in any case or in the aggregate,
in any Material Adverse Effect on the business, operations, condition
(financial or otherwise), aggregate properties or aggregate assets of
Borrower or in any material liability on the part of Borrower.

               (f)  Financial Statements; No Material Adverse Change.  The
audited consolidated balance sheet of USMX (including Borrower) as of
December 31, 1995, and the related consolidated statements of income, cash
flow and stockholders' equity of USMX (including Borrower) for the period
then ended, audited by KPMG Peat Marwick LLP and the unaudited
consolidating balance sheets of USMX (including Borrower) as of March 31,
1996, and the related unaudited consolidating statements of income, cash
flow and stockholders' equity of USMX (including Borrower) for the period
then ended certified by officers of USMX and Borrower, copies of which have
been furnished to Lender, fairly present the financial condition of
Borrower and USMX as at such dates and the results of the operations of
such Persons for the periods ended on such dates, all in accordance with
GAAP consistently applied.  Neither Borrower nor USMX has on the date
hereof any material Contingent Liability or liability for taxes, long-term
leases or unusual forward or long-term commitments which are not reflected
in such financial statements or listed in Schedule 7.1(f).  Since such
date, except as previously disclosed in writing to Lender, neither the
business, operations or prospects of Borrower or USMX, nor any of their
respective properties or assets, have been affected by any occurrence or
development (whether or not insured against) which would result, either in
any case or in the aggregate, in a Material Adverse Effect on any such
Person.

<PAGE>

               (g)  Other Agreements.  Except for Material Agreements,
Borrower is not a party to any indenture, loan or credit agreement or any
lease or other agreement or instrument or subject to any charter or other
corporate restriction which would, upon a default thereunder or otherwise,
result in a Material Adverse Effect on Borrower, or materially impair the
ability of Borrower to carry out its Obligations under this Agreement, or
any of the Loan Documents.

               (h)  Information Accurate.  Except as disclosed to Lender on
Schedule 7.1(h) hereto, none of the information delivered to Lender by
Borrower or USMX in connection with the transactions contemplated by this
Agreement or the USMX Credit Agreement, including any representation or
warranty, contains any material misstatement of fact or omits to state a
material fact, and all projections contained in any such information,
exhibits or reports, including in particular the Feasibility Study and
Development Plan, were based on information which when delivered was, to
the best knowledge of Borrower, true and correct, and to the best knowledge
of Borrower all calculations contained in such projections were accurate,
and such projections presented Borrower's then-current estimate of its
future business, operations and affairs and, since the date of the delivery
of such projections, to the best knowledge of Borrower, there has been no
material change in the assumptions underlying such projections, or the
basis therefor or the accuracy thereof.

               (i)  Employee Benefit Plans. Except as disclosed on
Schedule 7.1(i), Borrower has not established, does not maintain and has
made no contributions to, nor has any liability with respect to, any Plan.

simple by Borrower which are subject to any of the Security Documents,

clear of all material defects of title, burdens on production or Liens
except Liens disclosed in Schedule 7.1(j) and specifically identified in
the Security Opinion delivered pursuant hereto.

                    (ii) With respect to those properties held under leases
or other contracts which are subject to any of the Security Documents:
(A) Borrower is in exclusive possession of such properties other than the
airstrip located on those properties and any navigable waters; (B) Borrower
has not received any notice of, and has no knowledge of any facts or
circumstances that, with the passage of time or notice, or both, could
result in any default of any of the terms or provisions of such leases or
contracts; (C) under such leases and contracts Borrower has the authority
to perform fully, and no provision thereof prohibits or would be breached
by Borrower's performance of, its obligations under this Agreement and the
other Loan Documents; (D) to the best of Borrower's knowledge and belief,
such leases and contracts are valid and are in good standing; and (E) to
the best of Borrower's knowledge and belief, the properties covered thereby
are free and clear of all defects of title or Liens, except for those
specifically identified in the Security Opinion or disclosed in
Schedule 7.1(j) [or in such leases or contracts.]  Borrower has delivered
or will make available to Lender all information concerning title to the
properties in Borrower's possession or control, or to which Borrower has
access, which Lender requests.

<PAGE>

                    (iii)     With respect to mining claims, leases and
other property interests (for purposes of this Section 7.1(j)(iii),
"Claims") which are subject to any of the Security Documents, except as

generally accepted standards of major companies in the mining industry
through the assessment year ending August 31, 1996]; (C) all maintenance
fees or rental payments have been duly and timely made in order to maintain
the Claims through the rental year ending August 31, 1996; (D) all
affidavits of assessment work and other filings required to maintain the
Claims in good standing have been timely recorded or filed with appropriate
Governmental Authority; and (E) Borrower has no knowledge of conflicting
claims or leases, except overlaps to avoid gaps or to maintain parallel end
lines, or inadvertent overstakings which do not materially impair
Borrower's property position.

                    (iv) Except as disclosed on Schedule 7.1(j), no
approval or consent of any Governmental Authority or any other party is
necessary to authorize the execution and delivery of the Mortgage, the
Second Mortgage, the Fourth Mortgage or of any other written Instrument
constituting or evidencing the Obligations.

               (k)  Securities Activities.  The proceeds of the Loan
hereunder will not be used to acquire any security in any transaction which
is subject to Sections 13 and 14 of the Securities Exchange Act of 1934, as
amended.  Borrower is not engaged in the business of extending credit for
the purpose of purchasing or carrying margin stock (within the meaning of
Regulation X of the Federal Reserve Board) or carrying any margin stock.

               (l)  Solvency.  Borrower is not entering into the
arrangements contemplated by this Agreement or any of the other Loan
Documents with actual intent to hinder, delay or defraud either present or

execution of the Hedging Agreement, after giving effect to the Loan, and
all such Instruments, and to any fees and expenses in connection with such
undertaking, (i) Borrower's property at a fair valuation, is, and will be,
greater than the sum of its Indebtedness (including its Contingent
Liabilities); (ii) the present fair salable value of Borrower's assets
exceeds, and will exceed, the probable liability of Borrower on its
Indebtedness (including its Contingent Liabilities) as they become absolute
and mature; (iii) Borrower has not, and will not have, incurred, and does
not intend to, or believe that it will, incur debts (including its
Contingent Liabilities) beyond its ability to pay such debts as such debts
mature (taking into account the timing and amounts of cash to be received
by Borrower from any source, and of amounts to be payable on or in respect
of its debts), and the cash available to Borrower after taking into account
all other anticipated uses of the cash, is, and is anticipated to be,
sufficient to pay all such amounts on or in respect of such debts
(including its Contingent Liabilities), when such amounts are required to
be paid; and (iv) subject to receipt of the Loan, Borrower has sufficient
capital with which to conduct its business and Borrower's capital does not
constitute unreasonably small capital with which to conduct its business.

OF MERCHANTABILITY, OR ANY WARRANTY OF ANY OTHER NATURE, SHALL BE IMPLIED.

               (n)  Capital Structure of Borrower and USMX.  Borrower is a
wholly-owned subsidiary of USMX.  Borrower has no outstanding obligations
to issue additional shares or other equity interests, including any stock

Borrower.

from any other Person that is a party to any such agreement.

               (q)  Taxes and Other Payments.  Borrower has filed all tax

and no claim for the same exists except as permitted hereunder, except any
such taxes, charges or amounts which are being diligently contested in good
faith by appropriate proceedings and for which adequate reserves in
accordance with GAAP have been set aside on the books of Borrower.

               (r)  Development Plan.  The Development Plan has been
prepared in accordance with prudent mining practices and after diligent
inquiry by Borrower, and Borrower is not aware of any facts or state of
affairs which would materially hinder or prevent Borrower from operating

achieving, after allowance for existing royalty burdens, the net Gold
production provided for therein.

shall be payable on demand.

          10.3 Conversion upon Acceleration.  Upon a Date of Default Lender
may, at its option and notwithstanding clause (ii) of Section 3.3(a),
convert any Gold Loan then outstanding into a Dollar Loan.  For the purpose
of computing the Principal Amount of any Loan outstanding after any
conversion pursuant to the foregoing sentence, any such Gold Loan shall be
converted into a Dollar Loan having a Principal Amount equal to the Dollar
Value (calculated at the date of conversion) of the Principal Amount of
such Gold Loan.  In addition, and upon any such Date of Default, Lender
may, at its option, elect that interest on the Principal Amount of the Gold
Loan converted as aforesaid which would otherwise be payable in Gold shall
instead be payable in Dollars at the Dollar Value thereof.  In addition, if
upon any such Date of Default, or for purposes of obtaining a judgment in
any court for any purpose hereunder (including a proceeding under Title XI
of the United States Bankruptcy Code), it becomes necessary to determine
the Dollar Value of any payment obligation hereunder (whether with respect
to a Principal Amount or interest) which is payable in Gold (a "Gold
Obligation"), such determination shall be made at the time (or from time to
time) and to the extent payment (in whole or in part) has actually been
made by Borrower or USMX or a judgment has been rendered.  If the amount of
Gold that could be purchased at the time and with the proceeds of any such
payment or judgment is not sufficient to satisfy in full the relevant Gold
Obligation, the Borrower hereby indemnifies and holds harmless Lender:

               (a)  with respect to such deficiency; and

               (b)  from all costs and expenses incurred in the event that,
as a result of any default by Borrower or USMX hereunder or under any other
Loan Document, such Lender, at its own expense, must, at any time or from
time to time purchase Gold in an open exchange market to satisfy its
obligations to any funding source which has provided Gold to Lender to
make, in whole or in part, the Gold Loan.

<PAGE>

          Such indemnity obligations of the Borrower:

               (c)  shall be payable in Dollars;

               (d)  shall be determined in accordance with (and at times
provided pursuant to) this Section; and

               (e)  shall be enforceable, insofar as clause (a) is
concerned, as a separate or additional cause of action, and such
enforceability shall not be affected by any prior judgment being obtained
for any other sums due under this Agreement or any other Loan Document.

                              PER PRO


                              N M ROTHSCHILD & SONS LIMITED



                            GUARANTY


          This GUARANTY (the "Guaranty"), dated as of July 11,
1996, is made by USMX, INC., a Delaware corporation
("Guarantor"), in favor of and for the benefit of N M ROTHSCHILD
& SONS LIMITED, a company organized and existing under the laws
of England ("Lender").


                            RECITALS

          A.   Pursuant to a certain Credit Agreement dated as of
July 11, 1996 by and between USMX OF ALASKA, INC., an Alaska
corporation and wholly-owned subsidiary of Guarantor
("Borrower"), and Lender (as amended, modified, supplemented or
extended, the "Credit Agreement"), Lender has agreed to make
certain loans in Gold or in Dollars to Borrower (the "Loans"), to
be used by Borrower for purposes of funding expenditures and
working capital at the Project (having the meaning set forth in
the Credit Agreement) and for general corporate purposes.

          B.   Lender's obligation to make Loans under the Credit
Agreement is conditioned on Guarantor having executed and
delivered this Guaranty, and this Guaranty being in full force
and effect.

          C.   This Guaranty is given by Guarantor in favor of
Lender to guaranty the Obligations of Borrower in accordance with
the terms of the Credit Agreement and this Guaranty.


                           AGREEMENT

          NOW, THEREFORE, (i) in order to set forth Guarantor's
guaranty of the Loans made pursuant to the Credit Agreement,
(ii) to comply with the terms and conditions of the Credit
Agreement, (iii) to induce Lender to make the Loans to Borrower
pursuant to the terms of the Credit Agreement, (iv) at the
special insistence and request of Lender, and (v) for other good
and valuable consideration, the receipt and sufficiency of which
are hereby acknowledged, Guarantor hereby covenants and agrees to
and with Lender as follows:

          1.   Defined Terms.  Unless otherwise defined herein,
capitalized terms used in this Guaranty have the meanings
assigned to such terms in the Credit Agreement.

          2.   Guaranty.

               (a)  Guarantor hereby guarantees, absolutely and
unconditionally, the prompt and complete payment and performance
of the Obligations when due (whether at the stated maturity, by
acceleration or otherwise) and at all times thereafter, provided

<PAGE>

that, on or after Completion of the Project, if no Default or
Event of Default is outstanding, Lender's sole recourse under
this Guaranty shall be to the Pledged Collateral (defined in the
Pledge and Security Agreement of even date herewith between
Guarantor and Lender (the "Pledge Agreement") and the collateral
subject to the Assignment Agreement, of even date herewith,
between Guarantor and Lender (the "Assignment Agreement"), other
than for Obligations of Borrower which arise under a breach of
the representation in Section 7.1(t) of the Credit Agreement or
the covenants in Section 8.1 of the Credit Agreement insofar as
Environmental Laws are concerned, the guarantee of which
hereunder shall remain unchanged and unaffected by Completion,
and shall remain the full recourse obligation of the Guarantor.
Guarantor also agrees to pay:

               (i)  any and all expenses (including attorneys'
          fees and disbursements) related to any failure of
          Borrower to pay or perform any Obligation of the
          Project guaranteed hereunder, which may be paid or
          incurred by Lender in enforcing any rights with respect
          to, or collecting, any or all of the Obligations of
          Borrower guaranteed hereunder; and

               (ii) any and all expenses (including attorneys'
          fees and disbursements) related to or arising from
          Lender's enforcement of this Guaranty and collecting
          against Guarantor under this Guaranty

          The guarantees and obligations of this Section 2(a) are
collectively the "Guaranteed Obligations".

               (b)  Guarantor agrees that this Guaranty
constitutes a guaranty of payment and not of collection, and
Lender shall not be obligated to initiate, pursue or exhaust any
form of recourse or obtain any judgment against Borrower or
others (including other guarantors) or to realize upon or exhaust
any collateral security held by or available to Lender before
being entitled to payment from the undersigned hereunder.  The
liability of Guarantor shall not be limited, diminished or
affected by (i) any condition of Borrower or Guarantor (including
bankruptcy, liquidation or dissolution) or failure by Lender to
file or enforce any claim against the estate (in administration,
bankruptcy, dissolution or otherwise) of Borrower, Guarantor or
others, (ii) the fact that recovery from Borrower or any other
person is barred by any statute of limitations, invalidity,
illegality, unenforceability or for any other reason or that
Borrower or Guarantor have valid defenses, claims or offsets
(whether at law, in equity or by agreement), (iii) any amendment,
modification or change of any kind or nature to the Credit
Agreement, the Loan Document, the Notes or this Guaranty, or any
Instrument or understanding executed or entered into pursuant to
the Credit Agreement, (iv) any adjustment, indulgence,
forbearance or compromise granted by Lender to Borrower or
Guarantor, or (v) any other circumstance which might otherwise
constitute a legal or equitable discharge of a guarantor.
Guarantor renounces all benefits of discussion and division and
waives diligence, presentment, protest, notice of dishonor,
protest or default, demand for payment upon Borrower or the
undersigned, notice of acceptance of this Guaranty, notice of any
addition to or increase or decrease in the Obligations, and all
other notices and demands whatsoever.

               (c)  This Guaranty is a continuing guaranty, and

<PAGE>               
               
it will not be discharged until payment in full of all of the
Guaranteed Obligations and cancellation of this Guaranty by
Lender ("Termination") and will remain in full force and effect
notwithstanding any interruption in the business relations
between Borrower and Lender or any increase or decrease from time
to time in the amount of the Obligations.

               (d)  Guarantor hereby acknowledges and agrees that
subject to the limitations set forth in Section 2(a):  (i) it is
personally obligated and fully liable for the amount due under
this Guaranty (i.e., for all Guaranteed Obligations hereunder);
and (ii) the Lender has the right to sue on this Guaranty and
obtain a personal judgment against Guarantor for satisfaction of
the amount due under this Guaranty either before or after a
judicial foreclosure of the Deed of Trust under Alaska Statute
09.45.170 - 09.45.220.

          3.   Guaranty Secured.  Payment and performance under
this Guaranty is secured by pledges, encumbrances and security
interests in certain collateral pursuant to the Pledge Agreement
and the Assignment Agreement.  Reference is hereby made to the
Pledge Agreement and the Assignment Agreement for a definition
and description of such collateral so encumbered to secure all
the obligations of Guarantor hereunder.

          4.   Lender's Rights.  Guarantor authorizes Lender,
without notice or demand and without affecting Guarantor's
liability hereunder, to take and hold security for the payment of
this Guaranty and/or any of the Guaranteed Obligations, and
exchange, enforce, waive and release any such security; and to
apply such security and direct the order or manner of sale
thereof as Lender, in its discretion, may determine; and to
obtain a guaranty of the Guaranteed Obligations from any one or
more Persons and at any time or times to enforce, waive,
rearrange, modify, limit or release any of such other Persons
from their obligations under such guaranties.  Guarantor hereby
acknowledges and agrees that the obligations of all Persons to
pay and satisfy the Guaranteed Obligations pursuant to their
respective agreements or guaranties (including Guarantor's
obligations hereunder) shall be joint and several.

          5.   Effectiveness; Reinstatement.  This Guaranty shall
continue to be effective, or be reinstated, as the case may be,
if at any time payment, or any part thereof, of any of the
Guaranteed Obligations is rescinded or must otherwise be restored
or returned by Lender upon the insolvency, bankruptcy, dissolu
tion, liquidation or reorganization of Borrower, or upon or as a
result of the appointment of a receiver, intervenor or
conservator of, or trustee or similar officer for, Borrower or
any substantial part of its property, or otherwise, all as though
such payments had not been made.  Borrower and Lender may modify,
rearrange, extend for any period and/or renew from time to time
the Guaranteed Obligations without notice to Guarantor, and in
such event the obligations of Guarantor with respect to the
Guaranteed Obligations shall not be released, discharged or
reduced and Guarantor will remain fully bound hereunder on such
Guaranteed Obligations.  This Guaranty may be enforced by Lender
and any subsequent holder of the Guaranteed Obligations and shall
not be discharged by the assignment or negotiation of all or a
part of the Guaranteed Obligations.

          6.   Default.  If Borrower has failed to pay or perform
when due the Guaranteed Obligations or there is an event with
respect to Guarantor that would require or permit the accelera

<PAGE>

tion pursuant to the Credit Agreement of any outstanding loan,
then all of the Guaranteed Obligations shall be immediately due
and payable by Guarantor, regardless of whether the payment of
the Guaranteed Obligations has been accelerated or Borrower is in
default with respect to the Guaranteed Obligations.

          7.   Merger.  This Guaranty shall not be affected by
any change in the name of Borrower, or by the acquisition of
Borrower's business by any person, firm or corporation, or by any
change whatsoever in the objects, capital structure or consti
tution of Borrower, or by any merger, amalgamation or consolida
tion of Borrower with any corporation, or by any dissolution or
liquidation of Borrower, but shall, notwithstanding the happening
of any such event, continue to apply to all the Obligations
whether theretofore or thereafter incurred, and in this instru
ment the word "Borrower" shall include every such person, firm,
partner and corporation and all successors of the customer.
Guarantor shall promptly notify Lender of any change or event
described in this Section 7.

          8.   No Waiver.  Lender shall not be obligated to
exercise any right, power or privilege hereunder, and no failure
to exercise and no delay in exercising, on the part of Lender,
any such right, power or privilege shall operate as a waiver
thereof, nor shall any single or partial exercise thereof
preclude any other or further exercise thereof or the exercise of
any other right, power or privilege.  No notice to or demand on
Guarantor shall be deemed to be a waiver of the right of Lender
to take further action without notice or demand as provided
herein.  No waiver shall be applicable except in the specific
instance for which given, nor in any event shall any modification
or waiver of any provision of this Guaranty be effective unless
in writing and signed on behalf of Lender.

          9.   Representations and Warranties.

               (a)  In order to induce Lender to make the Loans
to Borrower pursuant to the Credit Agreement, Guarantor
represents and warrants to Lender (which representations and
warranties will survive the creation of the Guaranteed
Obligations and any extension of credit under the Credit
Agreement) that:

                    (i)  Benefit to Guarantor:  Guarantor's
          guaranty pursuant to this Guaranty reasonably may be
          expected to benefit, directly or indirectly, Guarantor;

                   (ii)  Familiarity and Reliance:  Guarantor is
          familiar with, and has independently reviewed the books
          and records regarding, the financial condition of
          Borrower and is familiar with the value of any and all
          collateral intended to be created as security for the
          Notes and Guaranteed Obligations.  Notwithstanding the
          foregoing, Guarantor is not relying on such financial
          condition or the collateral as an inducement to enter
          into this Guaranty;

                  (iii)  No Representation:  Neither Lender nor
          any other person, corporation or entity has made any
          representation, warranty or statement to Guarantor with
          regard to Borrower or its financial condition in order

<PAGE>          
          
          to induce Guarantor to execute this Guaranty; and

                   (iv)  Guarantor's Financial Condition:  As of
          the date hereof and after giving effect to this
          Guaranty and the contingent liability evidenced hereby,
          Guarantor is and will be solvent, and has assets which,
          fairly valued, exceed its obligations, liabilities and
          debts.

               (b)  Additional Representations.  Guarantor hereby
adopts and makes the representations, warranties and covenants

     (ii)    Forward Transactions

                    We may purchase from you and/or sell to you

B.   Fixed Rate Forwards

     (i)     Premium

                    Unless the parties agree otherwise and
             subject to paragraph 5.D., the forward premium for a
             Fixed Rate Forward will be determined by reference
             to the then prevailing market interest rates for the
             period of the Forward applied to the Spot Price.
             The forward premium will be calculated on an annual
             basis based on a 360-day year.

     (ii)    Settlement

                    You may settle any Fixed Rate Forward on its
             Maturity Date on giving us not less than two

             out such Forward by either:

                         (a)  entering into a matching Forward at

                    with the matching Forward Price being
                    determined in accordance with the terms of
                    this letter.  The difference between the
                    original Forward Price and the matching
                    Forward Price multiplied by the Metal
                    Quantity will be paid on the Maturity Date;
                    or

                         (b)  entering into a matching Spot on
                    the Maturity Date of the original Forward at
                    a price based, at your election, on:

                                   (1)  our prevailing spot price
                         by reference to the market prices quoted
                         two Business Days before the Maturity
                         Date; or

                                   (2)  the morning London Gold
                         Market US Dollar Fixing Price two
                         Business Days before the Maturity Date;
                         or

                                   (3)  in the case of silver,
                         the London Silver Market spot US Dollar

                              cash payment of the amount equal to
                    the product of the Metal Quantity and the
                    difference between the original Forward Price
                    and the matching spot price will be made on
                    the Maturity Date.

                 (i)  New Forward

                    At the time you close out a Fixed Rate
             Forward under this letter you may elect to enter
             into a new Forward in the same Metal Quantity with a
             Maturity Date and Forward Price determined in
             accordance with the terms of this letter.

             (ii)   Conversion

                    As an alternative to closing out a Fixed Rate
             Forward you may elect on not less than two Business
             Days' prior notice to settle such Forward by
             requesting us to convert it into a Floating Rate
             Forward.

C.   Floating Rate Forwards

     (i)     Premium

<PAGE>

                         (a)  Unless the parties agree otherwise,
                    and subject to the remainder of paragraph
                    5.C., the forward premium for a Floating Rate
                    Forward will be determined by us by reference
                    to market interest rates for gold and Dollars
                    for successive floating rate periods (each a
                    "Floating Rate Period") over the term of the
                    Forward.

                         (b)  In calculating the gold or silver
                    floating rate of interest, the purchaser may
                    elect for one or more tranches of the gold or
                    silver (as the case may be) purchased
                    pursuant to a Forward to be subject to our
                    quoted rate for an interest period agreed by
                    the parties which does not exceed thirty-six
                    months, PROVIDED that each such tranche
                    comprises at least 5,000 fine ounces of gold
                    or (as the case may be) 50,000 ounces of
                    silver.

                         (c)  If a Forward is not settled on the
                    last day of a Floating Rate Period, the
                    accrued forward premium will be aggregated
                    with the Spot Price for such Forward, such
                    aggregate being the new Spot Price for the
                    succeeding floating rate period.  The forward
                    premium for the succeeding floating rate
                    period will be calculated by reference to and
                    will apply to such new Spot Price.  Forward
                    premiums shall be aggregated in such manner
                    to each successive floating rate period until
                    settlement.

                         (d)  If you elect to settle a Floating
                    Rate Forward prior to the Rollover Date (as
                    defined below), the accrued forward premium
                    will be calculated by discounting to present
                    value the forward premium for said floating
                    rate period from the date of settlement to
                    the last day of such period at the rate
                    determined by us by reference to the market
                    for the unexpired portion of such period.

                         (e)  The forward premium will be
                    calculated on an annual basis based on a 360-
                    day year.

     (ii)    Floating Rate Periods

                    You may select the duration of each Floating
             Rate Period provided that:

<PAGE>

                         (a)  you notify us no later than two
                    Business Days before the beginning of the
                    relevant Floating Rate Period of such
                    duration; and

                         (b)  the first Floating Rate Period will
                    commence two Business Days after the date on
                    which we enter into the relevant Floating
                    Rate Period; and

                         (c)  no Floating Rate Period shall
                    extend beyond the Maturity Date.

     (iii)   Rollover

                    On the last day of each Floating Rate Period
             (the "Rollover Date" and the last Rollover Date
             shall fall on the Maturity Date) you may on
             notifying us no later than two Business Days before
             such Rollover Date:

                         (a)  Settle; or

                         (b)  close out the Forward in accordance
                    with paragraph 5.C.(iv)(b)(2), except that
                    (1) if the Floating Rate Period ends on the
                    Maturity Date, the appropriate Spot Price
                    will be the relevant quotes two Business Days
                    before the Maturity Date and (2) the Forward
                    Price will not be discounted to present
                    value; or

                         (c)  except where the Rollover Date is
                    the Maturity Date, elect that the relevant
                    Forward continues as a Floating Rate Forward
                    with a new Floating Rate Period and in the
                    same Metal Quantity, with the new Forward
                    Price determined in accordance with the terms
                    of this letter,

                    provided that if by 10:00 a.m. on the
             Rollover Date we have not received such notification
             we shall settle the Forward in such manner as we may
             in our discretion consider appropriate.

     (iv)    Settlement

             On any date prior to the Maturity Date of a
             Floating Rate Forward you may:

<PAGE>

                         (a)  on notifying us no later than two
                    Business Days before the proposed settlement
                    date Settle; or

                         (b)  except on Rollover Dates or the
                    Maturity Date close out such Forward by:

                                   1)   entering (except on
                         Rollover Dates or the Maturity Date)
                         into a matching Forward in the same
                         Metal Quantity and for the Rollover Date
                         for the relevant Floating Rate Period,
                         with the matching Forward Price being
                         determined in accordance with the terms
                         of this letter.  The difference between
                         the original Forward Price and the
                         matching Forward Price multiplied by the
                         Metal Quantity will be paid on the
                         Rollover Date.  In this subparagraph,
                         the Maturity Date shall be deemed to be
                         the Rollover Date if the Floating Rate
                         Period ends on the Maturity Date; or

                         paragraph 5.C.(iii)(b)) into a Spot in
                         the same Metal Quantity at a Spot Price
                         determined in accordance with the terms
                         of this letter.  The difference between
                         the Forward Price (discounted to present
                         value) and the Spot Price multiplied by
                         the Metal Quantity will be paid two
                         Business Days after the date of the Spot
                         is entered into.

D.   Fixing Commission

             on a London Fixing Price we will until further
             notice allow you a return commission of $0.05 per
             fine ounce (in the case of gold) and one-sixteenth
             of one percent of the price per ounce (in the case
             of silver).  In respect of your purchases of Metal
             from us based on a London Fixing Price we shall
             until further notice charge you Fixing commission at
             the rate of $0.15 per fine ounce (in the case of
             gold) and three-sixteenths of one percent of the
             price per ounce (in the case of silver).

             (ii)   If you use the London Fixing Price as a base
             price for a Forward, the forward premium will be
             calculated on such Fixing Price (excluding Fixing
             commission) and the relevant Fixing commission
             specified above will then be added to the Forward
             Price.

             the identical Metal placed with us but rather Metal
             of an equivalent quantity, type and assay.

             (v)    You shall not pledge, mortgage, charge or
             create any other form of encumbrance over Margin, or
             your rights in respect thereof, delivered (or to be
             delivered) to us (except liens in favor of
             N M Rothschild & Sons Limited), and such rights
             shall not be capable of being transferred, assigned,
             mortgaged, charged or otherwise dealt with in any
             way without our prior written consent.  At all times
             (whether before or after the occurrence of an Event
             of Default) your rights in respect of Margin
             provided hereunder shall constitute contractual
             rights for the delivery, subject to the provisions
             hereof, of identical amounts of gold (to the intent
             that you shall not retain any proprietary right to
             or entitlement in gold delivered as Margin to us and
             we shall be entitled in our absolute discretion to
             lend, lease, dispose of or otherwise deal with the
             same as the beneficial owner thereof).

                    Value for either party and to close out the
                    resultant open position by entering into a
                    matching transaction with you; and/or

                         (b)  to close out all outstanding Forwards

             of paragraphs 11.A(ii), (iii), (iv), (vi), (vii) and
             (viii), then we shall be deemed automatically and
             immediately to have exercised our rights set out in
             11.B(i)(a) and (b) above so as to reduce outstanding
             obligations between us to the payment of a single

     Having exercised our rights in accordance with
     paragraph 11.B.(i)(a) and (b) we shall:

             (i)    net the transaction amounts and quantities in
             the manner described in paragraph 12.A. and adjust
             any resulting amount to present value from the value
             date of the forward transaction and matching
             transaction to the close-out date by discounting
             such amount at the appropriate Eurodollar rate for
             the period concerned (as determined by us at our
             absolute discretion) assuming a 360-day year.

             (ii)   liquidate any of your property in our

<PAGE>             
             
             possession by sale or other commercially reasonable

             paragraph 11.C.(i) and (ii) above into US Dollars in
             such manner and at such rates as we may in our
             reasonable discretion determine.

The net resulting amount shall be paid by us to you or by you to

of the amount so determined and shall be in full and final
settlement and discharge of all payment and delivery obligations
between you and us under this letter.

             (i)    the amounts so payable or transferable by
             each party respectively in that currency or metal
             type shall be aggregated; and

             hereto ("the first party") exceeds the aggregate

             pay or transfer such aggregate amounts shall be
             deemed to be satisfied and discharged and replaced
             by an obligation on the part of the first party to
             pay to the other party an amount equal to such
             excess; and

             (iii)  if the aggregate amounts payable by each
             party hereto are equal, such amounts shall be deemed
             to be satisfied and discharged and no payment or
             transfer shall be made by either party in respect
             thereof.

                 REGISTRATION RIGHTS AGREEMENT


          THIS REGISTRATION RIGHTS AGREEMENT (this "Agreement")
is made as of July 11, 1996 by and between USMX, INC., a Delaware
corporation ("USMX"); and N M ROTHSCHILD & SONS LIMITED, a
company organized and existing under the laws of England ("NMR").

                            RECITALS

          A.   USMX and NMR are parties to a Credit Agreement
dated as of  July 11, 1996 (the "Credit Agreement"), pursuant to
which the loans provided for therein may, at the election either
of USMX or NMR, may be converted into shares of the common stock
of USMX (the "Shares").  In order to induce NMR to consummate the
transactions provided for in the Credit Agreement, USMX has
agreed to enter into this Agreement to provide certain
registration rights with respect to any Shares issued to NMR
pursuant to the Credit Agreement.

          B.   Certain capitalized terms used herein and not
otherwise defined are defined in Section 7 hereof.

                           AGREEMENT

          The parties hereto agree as follows:

          1.   Shelf Registration.  (a)  USMX shall:  (i) as
promptly as possible after Conversion file a Shelf Registration
Statement providing for resales of Registrable Securities by NMR
(the "Shelf Registration"); (ii) use its best efforts to cause
such Shelf Registration Statement to be declared effective as
promptly as is possible after filing; and (iii) use its best
efforts to keep the Shelf Registration Statement continuously
effective under the Securities Act with respect to the
Registrable Securities until the third anniversary of the date
hereof, or, if sooner, until the Shares no longer constitute
Registrable Securities.  USMX shall supplement or amend the Shelf
Registration Statement as necessary to comply with the Securities
Act and the rules and regulations thereunder, the rules,
regulations or instructions applicable to the registration form
used by USMX, or any other law, rule or regulation applicable
thereto.  USMX shall pay all Registration Expenses (as defined in
Section 4) incurred in connection with the Shelf Registration.

               (b)  In the event that USMX becomes ineligible to
file a Shelf Registration Statement on behalf of NMR, or the
Shelf Registration filed by USMX on NMR's behalf becomes
ineffective as a means of registering the Registrable Securities,
at any time after Conversion and at NMR's request, USMX shall use
its best efforts to register the sale of all or part of the
Registrable Securities.  USMX shall be required to file only one
registration statement to effect the foregoing.

<PAGE>

          2.   Piggyback Registrations.

               (a)  Right to Piggyback.  Whenever on or prior to
the third anniversary of the date hereof USMX proposes to
register any of its securities under the Securities Act to be
issued in an underwritten public offering by USMX (other than
pursuant to the Shelf Registration) and the registration form to
be used may be used for the registration of Registrable
Securities (a "Piggyback Registration"), USMX will give prompt
written notice to NMR of its intention to effect such a
registration and will include in such registration all
Registrable Securities requested for inclusion therein by NMR.

               (b)  Piggyback Expenses.  The Registration
Expenses related to the Registrable Securities in any Piggyback
Registration will be paid by USMX.

               (c)  Priority on Registrations.  If the managing
underwriters of a Piggyback Registration advise USMX in writing
that in their sole discretion the number of securities requested
to be included in such offering exceeds the number which can be
sold in such offering such that the offering will be materially
adversely affected, the number of securities to be offered will
be reduced as recommended in writing by the managing
underwriters.  USMX will include securities in such registration
according to the following priority:  (i) the securities USMX
proposes to sell, and (ii) the Registrable Securities requested
to be included in such registration and other securities
requested to be included in such registration by holders of
Parity Registration Rights, allocated among the holders of
Registrable Securities and such other holders in proportion, as
nearly as practicable, to the respective number of shares of
Common Stock proposed to be sold in such offering by them.

               (d)  Selection of Underwriters.  USMX may select
the investment banker(s) and manager(s) for any offering pursuant
to a Piggyback Registration.

               (e)  Other Registrations.  If USMX has previously
filed a registration statement with respect to Registrable
Securities pursuant to this Section 2, and if such previous
registration has not been withdrawn or abandoned, USMX will not
file or cause to be effected any other registration of any of its
equity securities or securities convertible or exchangeable into
or exercisable for its equity securities under the Securities Act
(except on Form S-4, Form S-8 or any successor form), whether on
its own behalf or at the request of any holder or holders of such
securities, until a period of at least three months has elapsed
from the effective date of such previous registration, unless a
shorter period of time is approved by the holders of a majority
of the Registrable Securities included in such previous
registration.

          3.   Registration Procedures.  In connection with any
registration pursuant to Section 1 hereof, whenever NMR has
requested that any Registrable Securities be registered pursuant
to this Agreement, USMX will use its best efforts to effect the
registration and the sale of such Registrable Securities in
accordance with the intended method of disposition thereof and
pursuant thereto USMX will as expeditiously as possible:

               (a)  furnish to each Seller of Registrable
Securities such number of copies of such registration statement,
each amendment and supplement thereto, the prospectus included in

<PAGE>

such registration statement (including each preliminary
prospectus) and such other documents as such Seller may
reasonably request in order to facilitate the disposition of the
Registrable Securities owned by it;

               (b)  use its best efforts to register or qualify
such Registrable Securities under such other securities or blue
sky laws of such jurisdictions as NMR reasonably requests and do
any and all other acts and things which may be reasonably
necessary or advisable to enable each Seller of Registrable
Securities to consummate the disposition in such jurisdictions of
the Registrable Securities owned by such Seller, provided that
USMX will not be required to (i) qualify generally to do business
in any jurisdiction where it would not otherwise be required to
qualify but for this subsection, (ii) subject itself to taxation
in any such jurisdiction, or (iii) consent to general service of
process in any such jurisdiction except to the extent required by
applicable law;

               (c)  notify each Seller of Registrable Securities,
at any time when a prospectus relating thereto is required to be
delivered under the Securities Act, of the happening of any event
as a result of which the prospectus included in such registration
statement contains an untrue statement of a material fact or
omits any material fact necessary to make the statements therein
not misleading, and, at the request of any such Seller, USMX will
prepare a supplement or amendment to such prospectus so that, as
thereafter delivered to the purchasers of such Registrable
Securities, such prospectus will not contain an untrue statement
of a material fact or omit to state any material fact necessary
to make the statements therein not misleading;

               (d)  cause all such Registrable Securities to be
listed on each securities exchange on which similar securities
issued by USMX are then listed;

               (e)  provide a transfer agent and registrar for
all such Registrable Securities;

               (f)  enter into such customary agreements
(including underwriting agreements in customary form) and take
all such other actions as NMR reasonably requests in order to
expedite or facilitate the disposition of such Registrable
Securities;

               (g)  make available for inspection by any Seller
of Registrable Securities, any underwriter participating in any
disposition pursuant to such registration statement, and any
attorney, accountant or other agent retained by any such Seller
or underwriter, all financial and other records, pertinent
corporate documents and properties of USMX, and cause USMX's
officers, directors, employees and independent accountants to
supply all information reasonably requested by any such Seller,
underwriter, attorney, accountant or agent in connection with
such registration statement; and

               (h)  obtain a cold comfort letter from USMX's
independent public accountants in customary form and covering
such matters of the type customarily covered by cold comfort
letters (provided that such Registrable Securities constitute at
least 10% of the securities covered by such registration
statement).

          NMR agrees that, upon receipt of any notice from USMX

<PAGE>          
          
of the happening of any event of the kind described in
Section 3(c) hereof, NMR will forthwith discontinue disposition
of Registrable Securities pursuant to the registration statement
covering such Registrable Securities until NMR's receipt of
written notice that sales may continue with the existing
prospectus or the supplemented or amended prospectus contemplated
by Section 3(c) hereof.  In the event NMR is not able to commence
sales of Shares pursuant to an effective registration statement
not later than 60 days after the date of a notice pursuant to
Section 3(c) (the "Notice Date"), USMX shall pay to NMR an amount
per share equal to the difference (but only if the price in (ii)
is less than the price in (i)), if any, between (i) the actual
sales price subsequently received from any sales by NMR during a
number of days following the date on which such sales become
permissible which is equal to the number of days over 60 during
which such sales were not allowed and (ii) the average of (A) the
closing sales prices on any national securities exchange or the
NASDAQ National Market System on which the Common Stock is listed
or included, or (B) the average of the bid and asked prices on
NASDAQ if not so listed or included for the days in excess of 60
from the Notice Date (such average closing sales prices or
average bid and asked price, as the case may be, being referred
to as the "Deemed Sales Price"), plus interest calculated on the
Deemed Sales Price from the 61st day after the Notice Date to the
date of any actual sale at the rate of 12% per annum.

          4.   Registration Expenses.

               (a)  All expenses incident to USMX's performance
of or compliance with this Agreement, including, without
limitation, all registration and filing fees, fees and expenses
of compliance with securities or blue sky laws, printing
expenses, messenger and delivery expenses, and fees and
disbursements of counsel for USMX and all independent certified
public accountants, underwriters (excluding discounts and
commissions) and other Persons retained by USMX (all such
expenses being herein called "Registration Expenses"), will be
borne as provided in this Agreement, except that USMX will, in
any event, pay its internal expenses (including, without
limitation, all salaries and expenses of its officers and
employees performing legal or accounting duties), the expense of
any annual audit or quarterly review, the expense of any
liability insurance and the expenses and fees for listing the
securities to be registered on each securities exchange on which
similar securities issued by USMX are then listed.

               (b)  In connection with each registration of
Registrable Securities, USMX will reimburse NMR for the
reasonable fees and disbursements of one counsel chosen by NMR to
the extent such fees and disbursements exceed $2,500 up to a
maximum of $15,000.

<PAGE>

          5.   Indemnification.

               (a)  USMX agrees to indemnify NMR, its officers
and directors and any person who controls NMR within the meaning
of the Securities Act against all losses, claims, damages,
liabilities and expenses (including legal fees and other expenses
incurred in defending any such claim or action) caused by any
untrue or alleged untrue statement of material fact contained in
any registration statement, prospectus or preliminary prospectus
or any amendment thereof or supplement thereto or any omission or
alleged omission of a material fact required to be stated therein
or necessary to make the statements therein not misleading;
provided that USMX shall not be liable in any such case to the
extent that any such loss, claim, damage, liability (or action or
proceeding in respect thereof) or expense arises out of or is
based upon an untrue statement or alleged untrue statement or
omission or alleged omission made in such registration statement,
any such preliminary prospectus, prospectus, amendment or
supplement in reliance upon and in conformity with information
furnished to USMX in writing by NMR specifically for use therein.
If the indemnification provided for in this Section 5 is
unavailable to or insufficient to hold harmless NMR in respect of
any losses, claims, damages, or liabilities (or actions in
respect thereof) referred to therein, then USMX shall contribute
to the amount paid or payable to NMR as a result of such losses,
claims, damages, or liabilities (or actions in respect thereof)
in such proportion as is appropriate to reflect the relative
fault of USMX and NMR in connection with the statements or
omissions which resulted in such losses, claims, damages, or
liabilities (or actions in respect thereof), as well as any other
relevant equitable considerations.  The relative fault shall be
determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to
information supplied by USMX or NMR and the parties' relative
intent, knowledge, access to information, and opportunity to
correct or prevent such statement or omission.

          (b)  NMR agrees to indemnify and hold USMX, its
officers and directors and any person who controls USMX within
the meaning of the Securities Act harmless (in the same manner
and to the same extent as set forth in Section 5(a)) with respect
to any statement or alleged statement in or omission or alleged
omission from such registration statement, any preliminary
prospectus, prospectus, or any amendment or supplement thereto,
if such statement or alleged statement or omission or alleged
omission was made in reliance upon and in conformity with written
information furnished to USMX by NMR specifically for use
therein.

          6.   Participation in Registrations.  No Person may
participate in any registration hereunder unless such Person:

               (a)  in the case of a registration which is
underwritten, agrees to sell such Person's Registrable Securities
on the basis provided in any underwriting arrangements approved
by USMX;

               (b)  as expeditiously as possible, notifies USMX,
at any time when a prospectus relating to such Person's
Registrable Securities is required to be delivered under the
Securities Act, of the happening of any event involving such
Person as a result of which such prospectus contains an untrue
statement of a material fact or omits any fact necessary to make
the statements therein not misleading;

<PAGE>

               (c)  complies with all reasonable requests made by
USMX or its counsel with respect to the registration of such
Person's Registrable Securities, including, without limitation,
