Immediately following the Closing, the Company and ATIC will be the only stockholders of The Foundry Company, each of which at the Closing will have equal voting rights, and The Foundry Company will be owned 34.2 percent by the Company and 65.8 percent by Oyster on a fully converted to common basis.
