Am I required to repay sign-on bonus and relocation expenses based on upcoming job loss?

Points to consider:
1. Verbally offered an executive level position (Director) with full relocation package and significant sign-on bonus in mid-December 2015.
2. Accepted position (after some negotiation) both verbally and in writing in early January 2016
3. Part of the offer letter states that if I was to "resign" or " be terminated for misconduct" within [1-year for the sign-on bonus] and [2-years for the relocation expenses], I am to repay the bonus and any relocation expenses incurred by the company (on a pro-rated basis).
4. Upon relocating (to Iowa) and starting the job January 11, 2016, I learned the contract my company had with it's client had been cancelled (subsequent legal action by the company has been in play since that decision). Therefore, we're at a point which we're facing job elimination.
5. We (all site employees) are to receive 30-day notices of termination this week.
6. The company (graciously) is working feverishly to find the potentially displaced employees positions within the company in response to the contract cancellation.
7. Company is based in Tampa, Florida
