Damages shall be the amount that would be recoverable upon a tender less (a) the value of the security when the buyer disposed of it and (b) interest at six percent per annum from the date of disposition.

Such person may sue either at law or in equity to recover the consideration paid for the investment adviser services and any loss due to such investment adviser services, together with interest at six percent per annum from the date of payment of the consideration plus costs and reasonable attorney's fees, less the amount of any income received from such investment adviser services and any other economic benefit.

There shall be contribution as in cases of contract among the several persons so liable.
