      exercise of any such right or remedy shall preclude any other or further
      exercise of it or the exercise of any other right or remedy. Knowledge of

     registered with INDUSTRIAL AND COMMERCIAL ADMINISTRATION BUREAU of No. 38
     Zhujiang Road, Xinqu, Wuxi, P.R.C. (the "COMPANY").

Whereas:

(A)  The above parties made a master agreement with regard to the COMPANY on
     October 14, 2004 (the "MASTER AGREEMENT");

(B)  At the request of the relevant party and as a full payment of the total
     price for transfer of the TARGET EQUITY under the MASTER AGREEMENT, on
     Dec. 29, 2004 the TRANSFEREE respectively paid an amount equal to USD
     5,330,471.46 to KING PARTNER, an amount equal to USD 5,330,471.46 to
     LONGHUA, and an amount equal to USD 213,218.87 to QUANHUA MATERIAL (for the
     purpose of this SUPPLEMENTARY AGREEMENT, such payments are referred to as
     "PAYMENT IN PART"), as the preconditions related to the COMPANY, the
     TRANSFEROR and MR. PIAO under Clause 3.1 of the MASTER AGREEMENT (the
     "PRECONDITIONS") were not fully satisfied prior to the date of PAYMENT IN
     PART;

(C)  LONGHUA, MR. PIAO and the COMPANY agreed on Jan. 21, 2005, that LONGHUA
     shall transfer all the manufacturing machine equipments under its control
     to the COMPANY upon the date that MR. PIAO and LONGHUA reach a mutual
     agreement on

     the transfer. MR. PIAO shall pay the consideration for such transfer, and
     LONGHUA shall lease part of its workshop and space to the COMPANY at RMB
     50,000 per month as the charge for usage; and

(D)  After the MASTER AGREEMENT was signed, HUAYI SPECIAL STEEL, one of the
     COMPANY's subsidiaries, has changed the relevant business plan (for purpose
     of this SUPPLEMENTARY AGREEMENT, such changes refer to the following: HUAYI
     SPECIAL STEEL shall rent instead of purchasing the asset that it planned to
     purchase and the asset which Zhang Yanhua originally planned to invest into
     the COMPANY as the registered capital contribution with a lease term of 5
     years. After expiration of the 5-year term HUAYI SPECIAL STEEL shall
     transfer the residual fixed assets to Zhang Yanhua for free); HUAYI SPECIAL
     STEEL is undergoing restructuring (for purpose of this SUPPLEMENTARY
     AGREEMENT, such restructuring refers the following: HUAYI SPECIAL STEEL
     shall carry out capital reduction and transfer part of equity; after such
     capital reduction and transfer of partial equity, Zhang Yanhua shall not be
     shareholder of the COMPANY. The registered capital of the COMPANY shall
     decrease to RMB 25,500,000, of which the COMPANY shall hold 80% of the
     equity and MR. PIAO, on behalf of the COMPANY, shall hold the remaining 20%
     of the equity).

EACH PARTY agrees as follows:

1.   EACH PARTY agrees that PAYMENT IN PART:

     (1)  Shall be deemed as the TRANSFEREE has fully performed its obligation
          under Clause 2.2 of the MASTER AGREEMENT and the TRANSFEREE has paid
          in full the total price for the transfer; and

     (2)  Shall not be in any way understood or interpreted as any form of
          waiver of the Preconditions or waiver of rights under the MASTER
          AGREEMENT.

2.   EACH PARTY agrees that all the following Preconditions have been satisfied
     prior to the date of signing this SUPPLEMENTARY AGREEMENT:

          agreements and non-competition agreements satisfactory in form and

          filed and registered with the INDUSTRIAL AND COMMERCIAL ADMINISTRATION
          BUREAU.

3.   Each Party agrees that due to changes of HUAYI SPECIAL STEEL and its
     restructuring, the Preconditions under the MASTER AGREEMENT (including
     Clause 3.1.1(e) thereunder, Clause 13 in Appendix 3, and Appendix 9) with
     regard to the COMPANY, the TRANSFEROR and MR. PIAO have not been satisfied
     and the promises

     made by the COMPANY, the TRANSFEROR and MR. PIAO under Clause 4.1.12 of the
     Master Agreement have been broken (for purpose of this SUPPLEMENTARY
     AGREEMENT, such unsatisfied Preconditions and breaches are collectively
     referred to "NONCONFORMITY" ). For interests of the Parties,

     (1)  The TRANSFEREE hereby waives the right to request that the COMPANY,
          the TRANSFEROR and MR. PIAO continue to satisfy the aforesaid
          PRECONDITIONS and promises; and

     (2)  The COMPANY, the TRANSFEROR and MR. PIAO hereby commit to assume joint
          and several liability for any loss, damage and compensation, expenses,
          fees, debts or claims (including such loss, damages and compensations,
          expenses, fees, debts or claims as occur during defense of or
          settlement of claims for such liabilities) which the TRANSFEREE
          directly or indirectly suffered for the NONCONFORMITY with regard to
          HUAYI SPECIAL STEEL.

4.   After signing the SUPPLEMENTARY AGREEMENT, the COMPANY, the TRANSFEROR and
     MR. PIAO together shall issue a certificate to the TRANSFEREE, which
     specifies that all Preconditions (except that under Clause 3.1.1 of the
     MASTER AGREEMENT related to the TRANSFEREE) have been satisfied in
     accordance with the MASTER AGREEMENT and this SUPPLEMENTARY AGREEMENT.

5.   EACH PARTY agrees that the agreement signed by and between LONGHUA, MR.
     PIAO and the COMPANY on January 21, 2005 has violated their obligations
     under Clause 4.12 of the MASTER AGREEMENT (the "VIOLATIONS"). For interests
     of each party,

     (1)  The TRANSFEREE hereby waives the rights under the MASTER AGREEMENT for
          such VIOLATIONS and the corresponding remedies; and

     (2)  The COMPANY, the TRANSFEROR and MR. PIAO hereby commit to acquire
          ownership rights of all the manufacturing equipment of LONGHUA by the
          end of 2005.

     BONUS to Regalia Investments Holdings Ltd. ("Regalia"), as the
     representative of KING PARTNER, a limited liability company organized and
     existing under the laws of Malaysia, provided that King Partner issues an
     authorization letter authorizing the TRANSFEREE to make payment to Regalia,
     and a compensation commitment letter satisfactory to the TRANSFEREE. Under
     such circumstances, each payment to Regalia made by the TRANSFEREE in
     accordance with KING PARTNER's instructions shall be deemed as the
     TRANSFEREE's full performance of its obligation to pay the corresponding
     BONUS to KING PARTNER under the MASTER AGREEMENT.

7.   Unless otherwise clearly stipulated under this SUPPLEMENTARY AGREEMENT, the
     TRANSFEREE hereby retains all rights and remedies it may claim under the
     MASTER AGREEMENT.

This SUPPLEMENTARY AGREEMENT shall form an integral part of the MASTER AGREEMENT
and all terms in bold and italic used in this SUPPLEMENTARY AGREEMENT without
definition shall have the same meaning as those defined in the MASTER AGREEMENT.
In case of nonconformity or discrepancy between this SUPPLEMENTARY AGREEMENT and
the MASTER AGREEMENT, this SUPPLEMENTARY AGREEMENT shall prevail.

each Party with eight original copies both in English and in Chinese.
