Buyer may not audit records pursuant to this Section 3.5 more than once every twelve months.

ARTICLE IV- DETERMINATION OF PURCHASE COMMITMENT; PENALTY

4.1 Purchase Commitment Calculation. The Parties agree that the determination of whether the Purchase Commitment has been met shall be conducted (i) at the end of each calendar year during the term of this Agreement and (ii) within 45 days of the expiration of the term of this Agreement pursuant to Section 7.1, based upon the days in such calendar year in which this Agreement was in effect (each of clause (i) and (ii), a “Measurement Period”) by means of the following equation:

[Qualified Purchases / Total Worldwide Purchases] x 100% = Actual Purchase Percentage.

4.2 Procedure for Calculation; Damages. Within 20 days of the end of each Measurement Period, Buyer shall send Seller a written report that sets forth in reasonable detail Buyer’s calculation of (i) Qualified Purchases, (ii) Total Worldwide Purchases, (iii) the Actual Purchase Percentage for such Measurement Period and (iv) any Liquidated Damages due pursuant to Section 4.3, along with payment thereof. Seller shall then have 30 days to review each such report, during which Seller shall provide written notice to Buyer of any item thereon that is disputed by Seller. All such disputes shall be settled in accordance with Article IX hereof. Acceptance of any Liquidated Damages payment by Seller shall not act as a waiver by Seller of any inaccuracies in the calculation thereof.

4.3 Penalty for Failure to Meet Purchase Commitment. At the end of each Measurement Period in which the Actual Purchase Percentage is less than [***]%, Buyer shall pay Seller as direct and liquidated damages an amount in U.S. dollars determined by the following equation:

[Threshold Purchases- Qualified Purchases] x $[***] = Liquidated Damages.

Notwithstanding the foregoing, (i) for the 2008 Measurement Period, Buyer shall not be in violation of Section 2.1 hereof and no Liquidated Damages shall be payable and (ii) solely for the purpose of calculating whether any liquidated damages are due and payable for the 2009 calendar year Measurement Period, Unfulfilled Orders shall be based upon the Buyer Demand

Forecasts provided during 2009 as opposed to any Revised Demand Forecasts provided by Seller.

The report shall set forth in reasonable detail the basis for the calculations set forth therein. Seller’s receipt of such report shall not prejudice any rights or remedies of Seller under this Agreement for any inaccuracies or misstatements therein.

(b) When requested reasonably in advance by Seller, and subject to the execution of a standard form of confidentiality agreement for such engagements, Seller shall have the right for an independent third party that is reasonably acceptable to Buyer (the “Purchase Commitment Auditor”) to inspect, review and audit any and all records of Buyer and its Affiliates during normal business hours that are relevant to the calculation of the Actual Purchase Percentage, Liquidated Damages or other matters associated with this Agreement. It is understood that the Purchase Commitment Auditor shall be free to share any and all information discovered during such audit with Seller that relates to the matters set forth herein, but shall in no case disclose (i) the name of particular customers of Buyer or its Affiliates or (ii) specific prices paid for Product by Buyer, its Affiliates or its customers (other than for purchases from Seller or its Affiliates).

After such time, the discounts set forth in this Agreement shall apply to purchases of CARBOHYDROPROP™.

(b) If Buyer attains an Actual Purchase Percentage of [***]% or greater for any Measurement Period and the price of CARBOHYDROPROP™ increases from the level last offered to Buyer prior to the Effective Date, then for a period of [***] months from the date that both such conditions are satisfied, Seller shall not increase Buyer’s price for CARBOHYDROPROP™ above the rate charged in each Geographic Region immediately prior to the end of such Measurement Period.

For example, assume for 2008 (i) [***] pounds of Total HP Production, [***] pounds of Qualified Purchases and [***] pounds of Total CARBO Production.
