Alternative Earnest Money Deadline

In the Colorado Contract to Buy Sell, the Alternative Earnest Money Deadline is the time that you have to deliver Earnest Money, to the Seller, Seller's Agent, of Title Company.  In order to have a "contract", consideration has to be rendered.  Earnest Money is that consideration.  Allowing for a contingent delivery date of earnest money (the consideration), enables the buyers and sellers to deliver contracts via electronic deliver and still have an enforceable contract.
