                                        Conclusions

• Loss of 2nd Vendor for Superconducting Strand Removes
     Luxury of Generous Slack in Strand Procurement Schedule;
     Remaining slack now ~ 3 months

• 1st Vendor’s Superconducting Strand is of Excellent Quality;
  Responsive to Increased Order

• Pure Aluminum Quality Excellent; Contingent Quantity to be
  Ordered Soon

• Aluminum Alloy Quality Excellent, Vendor Responsive; Expected
  to Complete Successfully; Schedule has ~8 months slack
