Confidential Execution Version

3.3.2 Treatment of the Business Plan. The Parties expect the Company to comply with the Business Plan; provided, however, deviations from the Business Plan that result in an increase or decrease of less than twenty percent (20%) of the original cost or revenue to the Company attributable to such item as set forth in the Business Plan shall not require the consent of the Parties, so long as all such deviations in any given quarter do not represent a deviation of more than ten percent (10%) of total revenue or total expense, as the case may be, in the aggregate for the quarter in which the deviation occurs. No Party shall, however, have any assurance that the Company will achieve the Business Plan, except as to the number of wafers that each of FSL/AFSL and TPH/TPH-A commits to purchase in the Business Plan. In the event that FSL/AFSL or TPH/TPH-A, as applicable, has failed to purchase its applicable number of wafers in accordance with the Business Plan, then such Party shall compensate the Company for the shortfalls in the actual revenue of the Company attributable to its failure to purchase such wafers versus its share of the planned revenue set forth in the Business Plan.
