NOTE

US $16,012.50 April 15, 1997

Subject to the terms and conditions of this Note (this "Note"), ▇▇▇▇▇ ▇.
▇▇▇▇▇▇▇▇ ("Borrower"), for value received, the receipt and sufficiency of which
is hereby acknowledged, hereby promises to pay to the order of Metallurg, Inc.,
a Delaware corporation, or its successors or assigns ("MI"), in lawful money of
the United States of America in immediately available funds, the principal sum
of Sixteen Thousand Twelve Dollars and Fifty Cents ($16,012.50) payable together
with accrued interest thereon on the business day prior to the third anniversary
of the date hereof (the "Maturity Date").

1. Interest. From the date hereof through the Maturity Date and until the
Note is paid in full, this Note shall accrue interest on the unpaid principal
amount of this Note at a rate equal to 5.91% per annum compounded annually. All
interest shall be calculated on the basis of a three hundred sixty five or six
(365/6) day year and the actual number of days elapsed (including the first day
but excluding the last day) in the period for which interest is payable and
shall be payable in cash.

2. Events of Default. This Note and all accrued and unpaid interest hereon
shall become immediately due and payable if any one or more of the following
events, hereinafter called "Events of Default," shall occur and be continuing:

(a) there is a default in the payment of the principal of, or interest on,
this Note when the same becomes due and payable, at maturity or otherwise;

(b) Borrower shall (i) apply for or consent to the appointment of, or the
taking of possession by, a receiver, custodian, trustee or liquidator of itself
or of all or a substantial part of its assets, (ii) make a general assignment
for the benefit of creditors, (iv) file a voluntary petition in bankruptcy or
(v) be adjudicated a bankrupt or insolvent, or (y) an order for relief under any
relevant bankruptcy code shall have been entered in respect of Borrower; or

(c) without the application, approval or consent of Borrower, a case or
proceeding shall be instituted, in any court of competent jurisdiction, seeking
in respect of Borrower reorganization, dissolution, winding up or liquidation, a
composition or arrangement with creditors, the appointment of a trustee,
receiver, custodian, liquidator or the like of Borrower or of all or a
substantial part of the assets of Borrower, the issuance or levying of any writ,
judgment, warrant of attachment, execution or similar process against all or a
substantial part of the assets or business of Borrower; and, the same shall
continue undismissed, or unstayed and in effect, for any period of sixty (60)
consecutive days.

If there shall occur and be continuing an Event of Default, MI may, by
notice to Borrower, declare the principal under this Note and all interest
thereon payable, whereupon all principal under this Note and all such interest
shall become and be forthwith due and payable, without presentment, demand,
protest or further notice of any kind, all of which are hereby expressly waived
by Borrower; provided, however, that upon the occurrence of the Event of Default
specified in subparagraph (b) or (c) above, the principal under this Note and
all such interest shall automatically become and be due and payable, without
presentment, demand, protest or any notice of any kind, all of which are hereby
expressly waived by Borrower. In addition to the remedies set forth above, MI
may exercise any remedies provided by applicable law.

3. Prepayment. Borrower may prepay, without premium or penalty, all or any
portion of the outstanding principal amount of this Note together with accrued
and unpaid interest to such date of prepayment on such amount so prepaid.

4. Waiver. No failure or delay on the part of MI or any holder in
exercising any right, power or privilege hereunder and no course of dealing
between Borrower, MI or any holder shall operate as a

waiver thereof nor shall any single or partial exercise of any right, power or
privilege hereunder preclude any other exercise thereof or the exercise of any
other right, power, or privilege. The rights and remedies herein expressly
provided are cumulative and not exclusive of any rights or remedies which a
holder would otherwise have.

5. Amendment. This Note may not be amended except by an agreement in
writing signed by ▇▇▇▇▇▇▇▇ and MI or the holder hereof.

6. Notices. All notices and other communications under this Agreement
shall be in writing and shall be deemed given when delivered personally or
mailed by certified mail, return receipt requested, to the parties (and shall
also be transmitted by facsimile to the Persons receiving copies thereof) at the
