Pharma pre-nup: Pfizer, Wyeth to pay $billions if merger cancelled

Drugmakers Pfizer and Wyeth have filed a high-stakes prenuptial agreement with the Securities and Exchange Commission in advance of their planned $68 billion, job-destroying combination:

- If Pfizer can't quite raise the money it needs to do the deal, and cancels, it will pay Wyeth $4.5 billion

- If Wyeth changes its mind, it has to pay Pfizer $1.5 billion. Or $2.7 billion. Depends on how and when it pulls out.

For all their starry-eyed promises, they don't quite trust each other. Or the times.
Must be they've done this kind of thing before.
