◦	inaccuracy or breach of the representations and warranties of, or the non-compliance with covenants by, either party;

◦	the nonreceipt of closing documents; or

◦	for other reasons;

•	the possibility that there could be a delay in the completion of an acquisition, which could, among other things, result in additional transaction costs, loss of revenue or other negative effects resulting from uncertainty about completion of the respective acquisition;
