CALIPER LIFE SCIENCES ACQUISITION

RECONCILIATION OF PROJECTED DILUTION TO GAAP EARNINGS PER SHARE TO

PROJECTED ACCRETION TO ADJUSTED EARNINGS PER SHARE

Projected Accretion to Adjusted Earnings Per Share

We use the term “projected accretion to adjusted earnings per share,” to refer to projected dilution to GAAP earnings per share, excluding amortization of intangible assets, inventory fair value adjustments related to business acquisitions, other costs related to business acquisitions, and restructuring and lease charges, and including estimated revenue from contracts acquired in the Caliper Life Sciences acquisition that will not be fully recognized due to business combination accounting rules. We believe that this non-GAAP measure, when taken together with our GAAP financial measures, allows us and our investors to analyze the costs of producing and selling our products and the performance of our internal investments in technology and our internal operating structure, to evaluate the long-term profitability trends of our core operations and to calculate the underlying value of the core business on a dilutive share basis, which is a key measure of the value of the Company used by our management and we believe used by investors as well. Projected accretion to adjusted earnings per share also facilitates the overall analysis of the value of the Company and the core measure of the success of our operating business model as compared to prior and future periods and relative comparisons to our peers. We exclude amortization of intangible assets, inventory fair value adjustments related to business acquisitions, other costs related to business acquisitions, and restructuring and lease charges as these items do not represent what our management and what we believe our investors consider to be costs of producing our products, investments in technology and production, and costs to support our internal operating structure, which could result in overstating or understating

to our investors the performance of our operations. We include estimated revenue from contracts acquired with the Caliper Life Sciences acquisition that will not be fully recognized due to business combination rules. Our GAAP revenue for the periods subsequent to our acquisition does not reflect the full amount of revenue on such contracts that would have otherwise been recorded by the acquired businesses. The non-GAAP adjustment is intended to reflect the full amount of such revenue. We believe our investors will use this adjustment as a measure of the ongoing performance of the acquired businesses.

The non-GAAP financial measure described above is not meant to be considered superior to, or a substitute for, our financial statements prepared in accordance with GAAP. There are material limitations associated with non-GAAP financial measures because they exclude charges that have an effect on our reported results and, therefore, should not be relied upon as the sole financial measures to evaluate our financial results. Management compensates and believes that investors should compensate for these limitations by viewing the non-GAAP financial measures in conjunction with the GAAP financial measures. In addition, the non-GAAP financial measure included in this press release may be different from, and therefore may not be comparable to, similar measures used by other companies.
