I work at a company that got sold by another company with an indefinite LTA (long term agreement) in place. Former owner did not honor the LTA, but at least was transparant and timely about it. We got two years to sever several key processes. We will end up severing all ties, since the business risk of leaving open ends without the LTA is too big for my risk appetite. Fool me once. And that's our business consequence of not honoring an LTA even when the former owner severed the ties in good faith. If the buy-in is not there for both parties to the contract, then there is no ongoing relationship.
