There are so many ways to do an asset purchase; I would prefer an exchange of stock so I would not have any tax liability.
Lets say that Company A, whose stock is trading at $0.80 per share, wants to purchase EHRC Energy asset interest in block 2. Let’s value that interest at $3,000,000,000. ERHE Energy would form a new corporation, 100% owned by ERHC Energy and transfer its interest in block 2 into this new corporation, tax free. ERHC Energy then distributes this stock out as a dividend, shareholder choice as to treatment either as a dividend or a reduction in basis. Company A then exchanges 3,750,000,000 shares for all the shares of the newly formed company with block 2 interest. Shareholders now own 3.750 billion shares of company A, and all their shares of ERHC Energy, Block 3, 4,5 EEEZ, and no immediate tax consequences.
