**This discussion is for informational purposes only and is not tax advice. Each investor is urged to consult its tax advisor with respect to the application of the U.S. federal income tax laws to its particular situation as well as any tax considerations of the Reincorporation arising under U.S. federal estate or gift tax laws, the laws of any state, local or non-U.S.taxing jurisdiction or any applicable income tax treaty. 36

Treatment of the Reincorporation

The Reincorporation is intended to qualify as a “reorganization” for U.S. federal income tax purposes pursuant to Section 368(a)(1)(F) of the Code. As a result, a U.S. Holder generally should not recognize gain or loss upon the proposed Reincorporation. A U.S. Holder will have the same aggregate basis in its Nevada Corporation stock after the Reincorporation as such U.S. Holder had in the corresponding Delaware Corporation stock immediately before the Reincorporation. A U.S. Holder’s holding period in the Nevada Corporation stock immediately after the Reincorporation will include such U.S. Holder’s holding period in the corresponding Delaware Corporation stock immediately before the Reincorporation. Each U.S. Holder of shares of Company stock acquired on different dates and at different prices is urged to consult its tax advisor regarding the allocation of the tax basis and holding period of such shares.
