Statement of Operations Pro Forma Adjustments:

(a)Adjustment to the optoelectronics income statement is in regard to general and administrative, and sales and marketing expenses incurred by the corporate office which are allocated to each of the Company’s operating units. The amount presented represents the allocations to the optoelectronics operations that were not specifically identified as expenses of the optoelectronics operating unit. As a result of the Company reporting discontinued operations, EITF 87-24 does not allow corporate expenses to be allocated to the discontinued operations and the pro forma adjustment reverses this allocation to exclude these expenses from the discontinued operations results.

(b)Adjustment is associated reserves held on the Company’s corporate books that were associated with the discontinued optoelectronics operations. The adjustments were recorded on the Corporate books and the pro forma adjustment is made to reflect the activity in the discontinued operations results.
