                                 Loan Agreement

This Agreement is made by and between the person/company (hereinafter referred
to as "the Contract Signatory") and Chang Hwa Commercial Bank (hereinafter
referred to as "the Bank", including the Bank headquarters and all branches). It
is mutually agreed upon that the Contract Signatory undertakes all obligations
to the Bank under the terms and conditions specified as follows.

General Provision :

Article 1 All obligations prescribed in this Agreement includes all evidence of
          debts, liabilities and obligations, such as cheques, written
          acknowledgements of the indebtedness, money advances, debt securities,
          and other debts, including accrued interest, deferred interest,
          default penalty or indemnities, as well as other relevant payments of
          the Contract Signatory assigned to the Bank now (including all debts
          incurred in the past without being liquidated yet) or later.

Article 2 In the event that the name, organization, Articles of Incorporation,
          representative(s), the authorization of the representative(s) of the
          Contract Signatory or any other matter that would affect the rights
          and interests of the Bank is changed, the Contract Signatory shall
          forth with notify the Bank in writing of any such change, and complete
          the procedure of change or withdrawal of the identical seal. The
          Contract Signatory shall be liable for any transactions that occur
          before the above described notice or the procedure, and any damages
          suffered by the Bank as a result of its failure to notify.

Article 3 In the event the address of the Contract Signatory on this Agreement
          is changed, the Contract Signatory shall promptly inform the Bank of
          such change in written; otherwise the address of the Contract
          Signatory on this Agreement shall be deemed the mailing address of the
          Contract Signatory. Any document provided for in, or related to, this
          Agreement shall be deemed arrived as to all parties hereto when sent
          by the Bank within the ordinary time frame in mail delivery to either
          the address of the Contract Signatory on this Agreement or the latest
          updated address notified by the Contract Signatory to the Bank.

Article 4 Except for special clause provisions, the Contract Signatory is
          responsible for repayments of all obligations assigned to the Bank on
          monthly basis in accordance with respective interest rates agreed upon
          for

<PAGE>

          respective loan agreements between the Contract Signatory and the
          Bank. For any debt that the Contract Signatory owes the Bank and no
          specific interest rate is set forth in any agreement, the interest
          rate of such debt should be calculated based on the base rate
          announced by the Bank on that day of debt occurrence plus 3.5%.

Article 5 Calculation and Adjustment of Base Rate

          (1) Base rate is calculated based on the average of three-month period
              of "Interbank Weighted Averages of Daily Overnight Interest Rates"
              marking up "Base Rate Loan Pricing Factors of the Bank" (base rate
              loan pricing factors comprise operation cost, capital cost and tax
              of the Bank, the level of provision for bad debt, capital adequacy
              ratio, return on capital stipulated by the competent authority,
              etc.). In the event the markup of the "Base Rate Loan Pricing
              Factors" prescribed in the preceding paragraph changes due to the
              pricing factors, the bank may annually review and adjust the rate
              accordingly, depending on variation in loan market.

          (2) The weighted averages of daily overnight interest rates prescribed
              in the preceding paragraph is calculated based on weighted
              averages of overnight loan interest rates provided by "Interbank
              Money Center".

          (3) The base rate is regularly adjusted on a three month basis. The
              Contract Signatory acknowledges that the Bank will announce on the
              Bank's website information about the effective date of rate
              adjustment, calculation method and pricing of the base rate, so
              that the Contract Signatory could browse the said website to
              search the interest rate at anytime. The Contract Signatory agrees
              that the Bank is not required to inform the Contract Signatory of
              any adjustment of such base rate.

          (4) In the event of any enormous change in financial markets resulting
              in the divergence of the base rate of the Bank from market rates
              or cancellation of the weighted averages of daily overnight
              interest rates made by the Interbank Money Center, the Bank may
              make public such rate difference in business premises or on the
              website of the Bank, or newspapers or magazines ten (10) days
              before and adjust the base rate into other pricing base rate at
              its own discretion.

Article 6 When any one of the following events occurs, the Bank may at anytime

<PAGE>

          reduce the Contract Signatory's amount of credit line, shorten
          maturity period of the Contract Signatory's loan, or announce the
          demand date due of repaying all the obligations that the Contract
          Signatory owes the Bank without informing or repeatedly notifying the
          Contract Signatory in advance:

          (1) The principal and/or interest of any payable indebtedness have not
              been liquidated or repaid in any installment on the date due;

          (2) The Contract Signatory applies to the court for arranging a
              composition, adjudicating bankruptcy or corporate reorganization
              in accordance with Bankruptcy Law, or the Taiwan Clearing House
              announces that the Contract Signatory is denied credit, has ceased
              the business operation or redeems the indebtedness;

          (3) The Contract Signatory defaults to provide loan security in
              accordance with this Agreement;

          (4) Because of the death of the Contract Signatory, the heir(s) of the
              Contract Signatory declare limited succession or waiver of
              inheritance;

          (5) The Contract Signatory's principal property is subject to
              sequestration by the court owing to any criminal case.

Article 7 When any one of the following events occurs, the Bank may reduce the
          Contract Signatory's amount of credit line, shorten maturity period of
          the Contract Signatory's loan, or announce the demand date due of
          repaying all the obligations the Contract Signatory owes the Bank
          after informing or repeatedly reminding the Contract Signatory in
          advance within a reasonable time frame:

          (1) The interest of any payable indebtedness has not been repaid in
              accordance with respective agreements;

          (2) Securities are sealed up on government orders or lost, or the
              security values under warranty are decreased or deficient to
              guarantee the creditor's rights;

          (3) The actual purpose of this loan is not in compliance with the
              purpose approved by the Bank or the loan is not used as
              appropriate;

          (4) The Contract Signatory is under either treatment of enforcement,
              provisional seizure, provisional disposition or other safety
              disposition, so that the Bank may not make a claim for repayment
              for the obligations.

Article 8 The Contract Signatory agrees that the Bank has the right to directly

<PAGE>

          offset all obligations of the Contract Signatory assigned to the Bank
          from all kinds of deposit accounts at the Bank and by the creditor's
          right of the Contract Signatory to the Bank, which is applicable to
          any debt where the loan term is not matured. The obligation offsets
          shall be effective upon the Bank's deduction from the accounts of the
          Contract Signatory. Meanwhile, the bank deposit certificates, deposit
          books or other certificates issued from the Bank to the Contract
          Signatory will be voided within the offset amount of the obligations.

           and other debts of the Principal Obligor assigned to the Bank
           now(including all debts incurred in the past without being liquidated
           yet) or later.

Article 2  In the event the Principal Obligor defaults on the obligations upon
           expiration of the loan (including voiding the maturity period of
           loan), the Bank may directly request the Guarantors to repay the
           obligations without filing a lawsuit against the Principal Obligor or
           enforcing the assets of the Principal Obligor and/or securities in
           advance.

Article 3  The interest and deferred interest of all obligations assigned to the
           Bank shall be calculated in accordance with the respective interest
           rates agreed upon different debt certificates or other agreements
           between the Principal Obligor and the Bank. In the event there is any
           default penalty incurred, such penalty shall be calculated based on

           reimbursement is made, and 20% of the interest rate as penalty
           beginning at the next day after the expiration of six-month period

           continuously repay the indebtedness.
