bank. We hereby offer you to amend the aforementioned legal relationship
(hereinafter the “Legal Relationship”) as follows:”
As from the date on which this Amendment Offer is accepted, Zentraleuropa LPG
Holding GmbH may give RZB instructions to issue performance and payment
guarantees and also credit guarantees under the Legal Relationship (each a
“Guarantee”), provided always that:

  (i)  
each instruction shall (a) specify the beneficiary, the amount, the date of
issue and the date of expiry of the requested Guarantee, and (b) have the
wording of the requested Guarantee attached to it; and
    (ii)  
the term of the requested Guarantee is not more than 24 months from issuing of
the Guarantee; and
    (iii)  
the wording of the requested guarantee is acceptable to the Bank in form and
substance; and
    (iv)  
the amount of the requested Guarantee, together with all possible debit balances
under the Legal Relationship, shall not exceed EUR 8,000.000 (EURO eight
million).

Each instruction to issue a Guarantee shall be irrevocable.
The applicable Guarantee Fee for the aforementioned credit guarantees according

Should Guarantees issued by RZB according to the Legal Relationship be drawn in

Account of Zentraleuropa LPG Holding GmbH with RZB for the relevant foreign
currency in which said Guarantee is so drawn, RZB shall inform Zentraleuropa LPG
Holding GmbH and shall debit the amounts so drawn to the EUR-Current Account
unless Zentraleuropa LPG Holding GmbH provides the amounts in the relevant
foreign currency within two (2) Business Days. RZB will convert amounts paid
under a Guarantee into EURO on the basis of the daily exchange rate as of the
date of the payment under the relevant Guarantee. Insofar as there is no cover
for these amounts in the EUR-Current Account, Zentraleuropa LPG Holding GmbH
shall immediately pay these amounts to RZB for credit and deposit on the
EUR-Current Account.
The Applicable Margin for any possible debit balances on the Accounts according
to the Legal Relationship shall be 60.00 (sixty point zero) basis points per
