    Date: 22-05-07
   RECITALS
   A.
    
    The Parties have since 2004 cooperated in connection with a Trade Agreement dated 6 November
2004 (Trade Agreement) and underlying firm order letters for 2006 (dated 8. November 2005)
(Order Letter 2006) and for 2007 (dated 4 October 2006) (Order Letter 2007) pursuant to
which documents (together Existing Agreements), VESTAS has agreed to buy and ZOLTEK to sell
certain Products.
 B.
    
    Following negotiations the Parties wish to replace Existing Agreements with a new one.
thereby establishing the basis of a multiyear partnership securing carbon fiber capacity for
VESTAS, capacity expansion at ZOLTEK and maximize profit for both companies.
 C.
    
    The basis for the enlarged strategic partnership is the mutual expectation of a strong market
growth. In order to accommodate existing and future market demands technically and
commercially VESTAS thus expects from ZOLTEK to increase the available production capacity to
support VESTAS growth. Accordingly, VESTAS aims to enhance ZOLTEKs status as the preferred
supplier for the Products. This preferred supplier status will however be conditioned upon
competitive pricing, quality, delivery performance and available products.
 D.
    
    ZOLTEK on their side have informed and warranted to establish relevant manufacturing capacity
in the US and in Hungary based on the business scenarios and economical aspects presented in
order to accomplish VESTAS volume objectives.
 E.
    
    The cooperation of the Parties under the Existing Agreements have from time to time included
disputes and discussions relating to certain alledged failures by ZOLTEK to fulfilled agreed
orders and volumes at agreed dates under the Existing Agreements. The undertakings provided by
ZOLTEK and not the least the willingness of ZOLTEK to strengthen the preferred customer status
of
VESTAS and to introduce substantial investments for a prosperous future operation has
granted VESTAS sufficient comfort in order to enter into a revised strategic partnership
with ZOLTEK while at the same time  and as an integrated presumption of this Second Trade
Agreement  amicably settling such historic disputes/non-performance.

 F.
    
    Irrespective of the preferred relationship to be initiated and enhanced between the Parties,
ZOLTEK fully acknowledges that VESTAS cannot and will never be dependent upon only one
supplier on any component, materials etc. but must have freedom to operate with alternative
suppliers.
 G.
    
    Accordingly, by entering into this Second Trade Agreement, the Parties wish with effect from

 1.2

    The Agreement covers the Products stated in Appendix B and other products delivered from
ZOLTEK.3.
    
    Logistics3.1
    
    Orders and Order Confirmations  ContractsExcept as set forth below in Clause 3.2 regarding supplies of Products within the fixed
forecasting system (Firm Delivery Schedules), the Parties agree that VESTAS ordering
and purchase of Products shall be made by the exchange of an order issued by VESTAS
and an order confirmation issued by ZOLTEK (collectively a Contract). Any such
Contract shall be or be deemed made incorporating the terms and conditions of this
Agreement even without these documents being referred to or attached to such
Contract.It is emphasised that orders and order confirmations may for practical reasons
also be necessary with regard to orders and deliveries included in any Firm Delivery
Schedule due to accounting and shipment purposes. However, conceptually it is
emphasised that orders and deliveries as stated and included in any Firm Delivery
Schedule shall be considered as legally binding Contracts irrespective of whether
formal orders and order confirmations for practical reasons have been issued or not
in connection with VESTAS call for Products under a Firm Delivery Schedule. Hence
the existence or non-existence of such orders and/or order confirmations shall have
no effect on the legal binding nature of obligations under the Firm Delivery
Schedules.
