CHIMERA INVESTMENT CORP

APPENDIX I

ROE Calculation

For purposes of calculating the ROE, the Company’s net income is determined in accordance with GAAP, but excluding non-cash, non-operating expense items such as depreciation expense, amortization of goodwill and other non-cash, non-operating expense items as determined by the compensation committee in its sole discretion for the applicable performance period. If, for any portion of any performance period, (i) the Company does not use hedge accounting or (ii) its derivative hedging instruments or any portion thereof are otherwise deemed ineffective, which in either case, results in changes in the value of such hedging instruments being recorded in the Company’s GAAP income statement, then any gains or losses from such hedging instruments will also be excluded. The Company’s average equity under the employment agreements means the stockholders’ equity of the Company as determined in accordance with GAAP, but excluding accumulated other comprehensive income or loss (which, among other things, reflects unrealized gains or losses in the Company’s residential mortgage-backed securities portfolio), stockholders’ equity attributable to preferred stock and other items as determined by the compensation committee in its sole discretion for the applicable performance period. For purposes of calculating ROE, Company Average Equity will be determined based on the average of the Company’s stockholders’ equity calculated as described in the preceding sentence as of the last day of each quarter during the applicable performance period. Notwithstanding the foregoing, stockholders’ equity attributable to an issuance of common stock of the Company during the performance period shall be excluded from the calculation of “Company Average Equity” for a period of six months from such issuance.
