Yes, at 12% interest rate (with US rates around the zero mark), and warrants / options for about 10% of the company. One of the more expensive loans this year in the US

The $400m headline number is a little more complex;
'Oaktree will disburse $110 million as a loan and $140 million as part of a sale-and-leaseback transaction for some of Molycorp’s equipment when the financing closes, Doolan said. That’s expected “in the next several weeks,” President and Chief Executive Officer Geoffrey Bedford said on the call.
The remaining $150 million will depend on whether the company achieves two specific targets, which Doolan didn’t disclose. He said the company was “comfortable” with its ability to achieve them.'

So just like LYC, they have signed up to a distress situations lender and $150m depends on some secret targets that SH are not to be told about. Like the Sojitz deal where there are a load of metric to be met but never disclosed in any detail.

These sorts of lenders are trouble, but where do you go if no one else will lend to you?
