to Purchaser. The term Affiliate shall mean, with respect to Purchaser, any individual,
firm, corporation, division, association, partnership, joint venture, limited liability
company, organization or business (collectively Entity) that, directly or indirectly through
one or more intermediaries, controls, is controlled by or is under common control with
Purchaser. For purposes of this definition, controlmeans the ownership, directly or

##### 



4.1
    
    The Green Pipe Purchase Price shall be calculated based on Seller ́s totalex-works
mill cost each month, incorporating an 18% profit margin on total ex-works mill costs (this is
the same as a 21.95% mark-up on total ex-works mill costs excluding freight (which will be
billed as a separate line item without mark-up), an example of this calculation is provided in
Annex A(the Purchase Price). The Purchase Price for the Green Pipe will be in
EUROs and shall include European sales tax and all export taxes and duties, if applicable, to
Green Pipe. The Purchase Price for July 2007 production exceeding 46,667 metric tons for the
year (as referenced in the Whereas clause) is based on the pricing methodology herein and is
shown, as an example, in Annex B for each item and each specification. Deviations not
contemplated by Annex B shall result in separate calculation as described above.
Purchaser shall consult with Seller on any change in specifications and will not request
specifications which Seller cannot fulfill with commercially reasonable efforts. The Purchase
Price is calculated on an ex-works mill basis with freight on DES Houston full liner terms in
accordance with Incoterms 2000 to be added as a separate line item without margin. Upon
Purchasers request, the Green Pipe shall be delivered to a destination port other than
Houston. If any change in delivery terms pursuant to Purchasers request results in a higher
or lower cost to Seller, the Purchase Price shall be calculated separately.
   4.2
    
    Invoices will be submitted by Seller to Purchaser. Invoices will reference Purchasers
purchase order number and will contain such other information as Purchaser may reasonably
request. Purchaser shall effect payment within sixty (60) calendar days after notice of
readiness (or delivery order) (the Due Date). Purchaser shall pay interest on overdue
invoice payments that are not received within five (5) business days past the Due Date or are
not contested as provided in Section 3.3. The interested will be calculated from the Due Date
up to the actual date of payment at the rate determined to be three percent (3%) per annum
above the six months EURIBOR.
