ITEM 5. OTHER EVENTS.

      On June 18, 2003, Lightbridge, Inc., a Delaware corporation ("Lightbridge"
or the "Company"), announced a reorganization of its business to more
efficiently meet client needs and to respond to current economic conditions. The
Company also announced that Christine Cournoyer, President and Chief Operating
Officer, will leave the Company in July and Chief Executive Officer, Pamela D.A.
Reeve, will assume her duties.

      For the second quarter of 2003, the Company expects to record a
restructuring charge of approximately $700,000, in addition to the restructuring
charge of approximately $1.0 million announced earlier in the year for the
facilities consolidation in Broomfield, Colorado. The Company also expects
related and additional restructuring charges of approximately $3.6 million in
the third quarter and $200,000 in the fourth quarter of 2003. When fully
implemented, the action is expected to produce $7.0 to $8.0 million in
annual pre-tax cost savings, exclusive of new investments.

      Components of the reorganization include the closing of the Company's
Irvine, California facility, the transfer of key employment positions to its
Broomfield, Colorado facility, a headcount reduction of an estimated 70
positions, and future headcount additions in strategic business areas.

      The Company also reaffirmed its revenue guidance of $27.0 to $29.0 million
for the second quarter of 2003. At the same time, the Company reported it
expects a second quarter loss of $0.04 to $0.07 per share, after giving effect
to the restructuring charges.

commented on the actions described above, is included as Exhibit 99.1 to this
Current Report on Form 8-K and is incorporated by reference herein.
