APPENDIX Validus Agreed Acquisition of Western World

In presenting the Company’s results herein, management has included and discussed certain schedules containing diluted book value per common share that are not calculated under standards or rules that comprise U.S. GAAP. Such measures are referred to as non-GAAP. Non- GAAP measures may be defined or calculated differently by other companies. We believe that these measures are important to investors and other interested parties. These measures should not be viewed as a substitute for those determined in accordance with U.S. GAAP. Diluted book value per share is calculated based on total shareholders’ equity plus the assumed proceeds from the exercise of outstanding stock options and warrants, divided by the sum of unvested restricted shares, stock options, warrants and share equivalents outstanding (assuming their exercise). Diluted tangible book value per share is calculated based on diluted book value per share excluding goodwill and intangible assets per share. Investors should not rely on the information set forth in this presentation when considering an investment in the Company.
