It's a junk.

I once even signed one such contingent offer with expected salary. When the company won the award, it hired a different person with reduced salary. One year later, the same woman asked me to do her a favor again. I told her I felt shamed to get her phone.

Since that, I rejected to sign this kind of contingent offer four times last summer.

They will just use your qualifications to win the award from the government.
