Press release via CNN Money:
MEMC Electronic Materials, Inc. and Conergy (CGY.DE), announced that they have executed a definitive agreement for MEMC to supply solar grade silicon wafers to Conergy.
Under the terms of the definitive agreement, MEMC will supply solar wafers to Conergy over a 10-year period, with pre-determined pricing, on a take or pay basis beginning in the third quarter of 2008. Sales of the wafers over the 10-year period would generate between $7 billion and $8 billion in revenue for MEMC. As part of the definitive agreement, Conergy will advance funds to MEMC in the form of a capacity reservation deposit. In addition, MEMC will participate in 5% of the increase in value of Conergy's solar module/cell subsidiary....

MEMC shares jump on profits, solar deals
...In a note to clients, UBS said MEMC signed a 10-year deal to sell $7 billion to $8 billion worth of solar wafers to Conergy, and expanded its original 10-year deal with Gintech by another $700 million, for a contract now worth $3 billion to $4 billion.
UBS estimated that MEMC still has enough polysilicon left to sign one more customer for a 10 year deal worth $2 billion to $3 billion.
