How does a source code escrow arrangement come about?

Also sometimes referred to as two-party, master or open escrow arrangements. Multiple customers of the vendor then use the same software.

You can also implement both variants of escrow arrangements in a distribution or reseller variant if the software was provided through a distributor or reseller.
