The Borrower, Crystallex, Bolivar Aruba, Orinoquia, Revemin, the Initial Lender,
the Collateral Agent and the Administrative Agent are parties (the "ORIGINAL

Pursuant to the Agreement, the other Loan Documents and the Project Documents,

conditions provided in this First Amendment.

Standard Bank was and is the sole Initial Lender and on the date hereof is also

any other Affiliates of Crystallex under any Hedging Obligations.

NOW, THEREFORE, for good and valuable consideration, the receipt and adequacy
whereof is hereby acknowledged by each Party hereto, the Parties hereto hereby
agree as follows:

1.   The foregoing RECITALS are true and correct and are incorporated in this
     First Amendment; provided, however, that such agreement by the Initial
     Lender, the Collateral Agent and the Administrative Agent as to the fourth
     and fifth RECITALS is based solely upon the representations of Crystallex,
     which, solely for the purpose of this Section, the Initial Lender, the
     Collateral Agent and the Administrative Agent assume to be true and
     correct.

2.   The Agreement, the Loan Documents and the Project Documents, as executed
     and/or delivered by the Parties, or as any such Loan Documents are to be

     reference as if fully set forth herein, and shall remain in full force and
     effect in accordance with their terms, except as specifically amended or
     otherwise provided herein.

3.   The New Project Parties are each added as parties to the Agreement and as
     additional Project Parties solely for the purposes specifically stated
     herein. The New Project Parties each agree to be parties to the Agreement
     for such purposes and to be bound by all of the terms, conditions and
     provisions of this First Amendment, and to fully comply with their
     obligations hereunder.

     Agreement of this First Amendment or if the context otherwise requires and
     each notice and other communication delivered from time to time in
     connection herewith.

     as the Project, they will enter into discussions in order to adjust the
     repayment schedule described in this Section to reflect such additionally
     discovered and/or proven Reserves.

8.   Section 8.1.6 of the Agreement is amended in its entirety to read as
     follows:

     8.1.6    RECALCULATION OF BASE CASE

     (a) The Borrower shall, with the approval of the Administrative Agent, such
         approval not to be unreasonably withheld, update the Base Case from
         time to time at least on an annual basis, no later than each October 1,
         commencing October 1, 2001; provided, however, that the updated base
         case for October 1, 2001, shall be updated within sixty (60) days
         following the First Amendment Effective Date ("2001 DATE"). Any such
         updated Base Case shall be the Base Case for all purposes of this
         Agreement and each other Loan Document. If no agreement between the
         Borrower and the Administrative Agent can be reached on an updated Base
         Case by October 1 of the relevant calendar year thereafter (other than
         October 1, 2001), then the Borrower and the Administrative Agent shall
         negotiate further in updating the Base case so as to be acceptable to
         all parties (and may utilize the services of an independent expert);
         provided, however, that if such negotiations have not produced a Base
         Case acceptable to the Administrative Agent by November 30 next
         following, then the Base Case then in effect shall remain the Base Case
         for all purposes of this Agreement and each other Loan Document.
         Notwithstanding the foregoing, in the event that an updated Base Case
         is not agreed on or before the 2001 Date: (i) the draft "Corporate
         Business Plan" attached hereto as Exhibit A is hereby adopted as the


                                       3

<PAGE>




         Base Case, effective on the 2001 Date, and the proviso in the
         immediately preceding sentence shall not be given effect, and (ii) if
         the proviso in the third sentence of Section 8.1.6(a) becomes
         effective, such "Corporate Business Plan" shall be "the Base Case then
         in effect" for the purpose of such proviso. The Parties each
         acknowledge receipt of the electronic document described in Exhibit A
         and agree that a printed copy thereof need not be attached hereto.

     (b) Notwithstanding the provisions of clause (a), by an amendment to this
         Agreement by the parties hereto, or by separate written agreement of
         the Borrower and the Administrative Agent, a Base Case then in effect
         may be revised at any time prior to the adoption of an updated base
         case pursuant to clause (a) (a "REVISED BASE CASE"), to be effective
         until replaced by an updated Base Case or another Revised Base Case.

9.   The first sentence of Section 8.2.7(b) of the Agreement is amended in its
     entirety to read as follows:

     The counterparty to all Metal Trading Agreements shall be Standard Bank,
     unless the Administrative Agent shall, at the request of the Borrower but
     in the Administrative Agent's sole discretion, approve counterparties that
     are banks, other financial institutions or trading institutions having
     Indebtedness (with a maturity of one year or less) of Approved Credit
     Quality.

10.  The obligations of the Lenders to agree to the above amendments to
     Section 3.1.1 of the Agreement shall be subject to the prior or concurrent
     satisfaction of each of the conditions precedent set forth in this Section,
     unless the Administrative Agent shall, in its sole discretion, defer such
     satisfaction to a specified later date. Unless specifically stated to the
     contrary, each document, certificate and other Instrument delivered
     pursuant to this Section shall be dated on, or prior to, and shall be in
     full force and effect on, a Borrowing Date concurrent with or following the
     First Amendment Effective Date with respect to the Loan.

     The Administrative Agent shall have received:

     (a) Such evidence as the Administrative Agent shall reasonably require to
         the effect that Crystallex is the registered owner of the share capital
         of El Callao to be pledged hereunder, that El Callao is the registered
         owner of the share capital of ECM to be pledged hereunder, that ECM is
         the registered owner of the share capital of Osmin to be pledged
         hereunder, that Osmin is the registered owner of the share capital of
         Auriferous and that Auriferous is the owner of the Mining Rights as to
         the La Victoria Mine.

     (b) A certificate of an Authorized Representative of each Project Party and
         (without duplication) Subordinated Creditor to the effect that (i) the
         representations of such Person set forth in each Loan Document to which
         it is a party shall be true and correct as at the First Amendment
         Effective Date and (ii) no Default shall have then occurred and be
         continuing.

     (c) From Crystallex, each Project Party and (without duplication)
         Subordinated Creditor, a certificate of its Secretary or similar
         officer as to:

                    similar body (and if required, shareholders' resolutions)

                    and performance of this First Amendment and each Loan
                    Document ("NEW LOAN DOCUMENT") other than Loan Documents
                    authorized, executed and delivered prior to the date of this
                    First Amendment, and any other document to be executed by it

                    executed by it; and

              (iii) its Organic Documents as then in effect, upon which
                    certificate the Administrative Agent may conclusively
                    rely until it shall have received a further certificate of
                    the Secretary or similar officer of the relevant Person
                    cancelling or amending such prior certificate.
