Dryships - fleet expansion

Reference - http://www.reuters.com/article/marketsNews/idUSBNG17918220081006
Let me bring down a piece of information here on this vessel purchase and see if anyone wants to analyze.
Appreciate if any one wants to answer these questions.
1) The implied aggregate value of the fleet is estimated at $1,168 million.
(Question - Market cap of Dryships is less than 1B, that means the sale is bigger than the whole company equity..? Isn't this too aggressive? where is the company headed?
2) DryShips will pay to the Sellers $689.6 million in exchange for the shares of the SPCs. Such consideration will be in the form of 19,431,840 newly issued shares of DryShips Inc. common stock. Following the issuance of the new shares to the sellers, the total number of DryShips shares outstanding will be 62,984,840.
(Question - does that mean approximately 19M shares already given to the seller, or they pay later. If share value falls down further, does Dryships has to give more shares??. For today's prices its 70% of the equity)
3)The Company will also assume $216.3 million of existing debt
(Question - Does it means the seller previously owe this to Dryships or if understand incorrectly,does this mean Dryships has existing debt which they have cash for it?) - can some one clarify
4)$262.0 million in remaining shipyard installments related to these vessels which will be financed by debt facilities that are already in place
(I believe its the new debt Dryships want to take..Remember, its 30% of today's equity value of Dryships)
5)$16 million which will be funded by DryShips. ( I guess its the cash they hold in hand)
Disclaimer - I own some shares bought 3months back, and planning to hold. But I would definitely not buy any more with craziness of the above purchase.
