 CRITERIA FOR APPLYING DISCOUNTS BASED ON VOLUME 

 

	1.	Price shall be assigned during applicable month of product consumption or delivery and that shall be applicable to Monthly Contractual Volume of said month.


  

	2.	If Purchaser were to withdraw a volume exceeding Monthly Contractual Volume, price to be applied shall be that applicable to volume actually withdrawn for that month.


  

	3.	If Purchaser takes a volume lower than the Monthly Contractual Volume for reasons attributable thereto, the price to be applied shall be that related to Volume actually
taken during said month. 

  

	4.	if Purchaser takes a volume below the Monthly Contractual Volume for reasons attributable to Seller, the price to be applied shall be that related with the Monthly
Contractual Volume. 

  

	5.	In Purchaser takes a lower volume not less that **** of its Monthly Contractual Volume and considering these variations in the amount received by Purchaser and supplied
by Seller are owing to variations in capabilities of carrier vehicles supplied by Purchaser and/or to product loads (supply) of product manually performed by Seller (without mass measurements), price to be applied shall be that related with the
Monthly Contractual Volume. 

  

	6.	If volume taken by Purchaser is below the Monthly Contractual Volume for reasons attributable both to Seller and Purchaser, those reasons shall be analyzed and volume
attributable to each party in order to apply the relative price. 

  

	 	6.1	Taken volume at each assigned supply center shall be determined comparing it with volumes confirmed by Purchaser. 


 

	 	6.2	Compliance by each supply center shall be assessed determining any difference between confirmed volume and withdrawn volume. 


 

	 	6.3	Events of default for each determined difference in each supply center shall be analyzed. 


 

	 	64.	Using events of default in each supply center, volume attributable to either Purchaser or Pemex Gas y Petroquimica Basica shall be determined 


 

	 	6.5	The following shall be performed to each supply center: 









	 	6.5.1.	If default is attributable, in whole o in part, to Purchaser, and to compute volume, the confirmed Volume will be subtracted from not taken volume for a cause
attributable to Purchaser. 

  

	 	6.5.2.	If default is fully attributable to Seller, Confirmed Volume shall be used to count volume. 


 

	 	6.5.3.	In the event the confirmed volume or a volume exceeding thereof is withdrawn by Purchaser, the actually withdrawn amount shall be used in computing volume.


  

	 	6.6	Addition of computed volumes based on the above-mentioned paragraphs for each supply center, shall be applied to the relative price range. 


 

	7.	In regard to maintenance provided for in section 3.6.2., the following criteria shall be applied: 


 

	 	7.1	If Purchaser or Seller orders maintenance in a thirty day period and that term takes place in that same calendar month, price shall not be applicable since no
consumption was made. 

  

	 	7.2	If Purchaser or Seller requests maintenance at irregular intervals, that is, in various periods which periods involve diverse months in a calendar year, the parties
agree that price and applicable discount shall be that applicable to Base Contractual Volume on any relative month. 

 Criteria
set forth herein shall be compulsory for the involved parties, and may be amended by Seller, whenever Seller deems advisable.
