  It is well-known that all 2-knots are slice. Are all 2-links slice? This is
an outstanding open question. In this paper we prove the following: For any
2-component 2-link (J,K)in the 4-sphere which bounds the 5-ball B^5, there is
an embedded disc 2-disc D^2_J (respectively, D^2_K) in B^5 with the following
properties: J (respectively K) bounds D^2_J (respectively, D^2_K).
  D^2_J and D^2_K intersect transversely. the intersection of D^2_J and D^2_K
in D^2_J (respectively, D^2_K) is a trivial 1-knot.
