Initial question was

	  If a category C has pullbacs no terminal object, then has C finite
	  product?

Now, think of empty category (one without objects and morphisms):

(*) it doesn't contain terminal object
(*) it does have pullbacks of all pairs of objects (because there are none)
(*) it doesn't contain all finite products (as it doesn't contain limit
of empty diagram---terminal object)

Now, simplify _this_ counter-example. :)

Actually, if terminal object is considered as product of zero multipliers
(as it's usually does), then initial question contains answer in itself.
