Article 3. Restrictions on Set-off

The Guarantor shall not act against the Bank by setting off the relevant primary debt against any
of the Obligor’s deposit at and/or other claims/rights with respect to the Bank before such primary
debt becomes due or before the Guarantor must perform its/his/her guarantee obligation as a result
of pre-payment being required under Article 7 of the general terms and conditions for credit
transactions (in the case of corporate funds, including the occurrence of an event triggering a
promissory note repurchase request under Article 9).

Article 4. Relationship with Other Security • Guarantee Agreements

4.1 In case the Guarantor separately provides any collateral or guarantee in favor of the Bank with
respect to the same debt owed by the Obligor to the Bank, such collateral or guarantee, unless
agreed otherwise, shall not be changed by this Agreement and shall be applied cumulatively as being
separate from the guarantee obligation hereunder.

4.2 Notwithstanding 4.1 above, in case the Guarantor, pursuant to the request of the Bank concerned
about decrease in the value of a collateral or otherwise, guarantees jointly and severally the same
amount with respect to the same guaranteed obligation at the same time as such collateral is
provided, the other obligation shall be released if any one of them is performed in whole or part
to the extent of such performance.

Article 5. Change • Termination • Cancellation of Security, Etc.

The Bank may change, terminate or cancel other collaterals or guarantees as may be necessary for
the transaction if the Guarantor consents or if there is no adverse impact on claim enforcement
when the Guarantor subrogates such as, among others, substituting an existing collateral with a new
collateral of the same or higher value, replacing the Guarantor with a new guarantor of the same or
better qualification and ability, terminating or canceling the collateral or guarantee proportional
to the amount repaid in part.
