While we are prepared to extend an offer contingent upon a future point in the past becoming the present, it should be noted that said offer is non-binding unless and until Event XYZ (which may or may not occur depending on the successful completion of Action 123, which itself is subject to preconditional approvals and retroactive validations) is confirmed. Should Action 123 occur prematurely, the offer becomes simultaneously valid and invalid, pending a quantum audit. Please proceed accordingly, but not yet.
Seems pretty clear to me!!!
