    In the calculation of pro forma earnings, gross margin and
operating expenses, Mentor Graphics excludes amortization of acquired
intangibles and write-offs of in-process R&D from acquisitions. Also
excluded are non-operating and non-recurring items classified as
special charges such as restructure expenses and asset impairments, as
well as income tax expense in excess of a normalized 17% effective tax
rate. These excluded items are generally infrequent, less predictable
and are often non-cash in nature. Mentor Graphics believes that
excluding these items provides investors with a representation of its
core performance, and a pro forma base line for assessing the future
earnings potential of Mentor Graphics.
    These pro forma measures should be assessed in conjunction with
GAAP earnings measures for a more complete understanding of the
Company's results. Since pro forma measures exclude certain items,
differences in earnings from GAAP can be significant; Mentor Graphics
management evaluates its performance under both measures for a
complete understanding of its results. Investors are encouraged to
review both measures for their evaluations and consider the GAAP
earnings measures as the most complete measure of Mentor Graphics'
overall performance.
