Hi Brian,

Actually the redesign for the rev2 to rev3 was not the issue but the 
ProOne point in time.

SCI desired to pay less royalties as it was not designed by E-mu and a 
much cheaper product retail wise.

The Royalty rate was too high for such a product and SCI and E-Mu did 
not do enough negotiations in advance to clear the path to a reduced 
royalty stream.

The royalty covered the design work and software work provided by E-Mu 
Research over specific design. It should have been re-negotiated / 
agreed upon
before assuming all SCI products would have to pay royalties.

Royalties are fine if a NRE is absorbed over a number of units, but 
becomes a burden unless re-negotiated going forward.

A lesson to be learned about agreeing to a royalty plan without a clear 
end point.
