We define a Hamilton laceable graph G to be hyper-Hamilton laceable (hyper HL) if either In particular, the hypercube Qnis hyper HL. A graph G is caterpillar-spannable (CS) if it has a spanning tree which is a caterpillar. We present several theorems concerning products of CS graphs. It is shown that the product of two CS graphs such that at least one of them has maximum degree 3 is CS.
