RE:  SEPARATION AGREEMENT AND RELEASE

Dear Michael:

         This Agreement will confirm our mutual understanding with respect to
the arrangements we have made in connection with your resignation as an officer
of Lightbridge, Inc. ("Lightbridge" or the "Company") and the termination of
your employment.

         1.       RESIGNATION AS OFFICER; TERMINATION OF EMPLOYMENT.

         You hereby agree to resign as an officer of the Company effective
January 30, 2004. Your status as an employee and all employee benefits will also
be terminated effective January 30, 2004.

         2.       TRANSITION PERIOD.

         You will continue to perform in a professional manner your current
duties through the date of termination of your employment.

         3.       SALARY CONTINUATION PERIOD.

         If you sign this letter agreement and release (and do not timely revoke
your agreement as set forth in Paragraph 16), then for (i) a period from January
30, 2004, until December 31, 2004 (the "Salary Continuation Period"), your base
salary (less required withholdings and deductions for taxes) will continue to be
paid on the normal payroll cycle; provided, however, that if you commence
employment with a new employer, or if you engage in any paid consulting
activities during the Salary Continuation Period, then the income generated by
such employment or consulting work shall be deducted from the salary
continuation payments during the remainder of the Salary Continuation Period. In
addition, if you sign this letter agreement and release (and do not timely
revoke your agreement as set forth in Paragraph 16), you will receive a lump sum
severance payment of $40,000 in the payroll cycle following the expiration of
your revocation period. You agree that you will promptly notify the Company if
you commence new employment or engage in any paid consulting activities at any
time prior to December 31, 2004. Any paid consulting work that generates income
of an average of $ $2,400 per week or less

<PAGE>

during the Salary Continuation period shall not be subject to the notice
requirement or deduction as provided in this Paragraph 3. You agree that the
payments described in this letter agreement are above and beyond and in full
satisfaction of any payments or compensation otherwise owed to you under the
terms of your employment with Lightbridge or as required by law.

         4.       ACCRUED PAID VACATION AND TIME OFF.

         All accrued but unused vacation time earned through January 30, 2004
will be paid on that date.

         5.       VOICEMAIL, COMPUTER, AND RETURN OF COMPANY PROPERTY.

         Use of voicemail will be provided through the Salary Continuation
Period, and network access will also be provided through January 30, 2004. You
will return all other property, equipment and materials of the Company to the
Company promptly after January 30, 2004.

         6.       COBRA GROUP INSURANCE COVERAGE.

         As of January 30, 2004, you and your family members will be eligible to
continue your group health insurance coverage in accordance with the federal
COBRA law. Information about your rights under COBRA and forms for electing
continuation coverage will be provided to you by a separate letter on or about
January 30, 2004. If you or any of your family members elect to continue this
coverage, you and the Company will continue to pay the same share of the monthly
premium (subject to any carrier rate adjustments) as if you were still employed
throughout the Salary Continuation Period.

         7.       OUTPLACEMENT ASSISTANCE.

         To assist you in regard to outplacement, the Company will pay up to
$20,000.00 for outplacement services which are provided to you by a
Company-approved agency prior to the earlier of December 31, 2004 or the date
you commence new employment or paid consulting activities. Appropriate invoices
for outplacement services should be submitted promptly to the Company.

         8.       CONFIDENTIAL INFORMATION.

belongs exclusively to the Company, and that the confidential information of the
Company's customers or of other organizations with which the Company does
business remains their exclusive property. You agree that you will not use or
disclose any such confidential information, whether for your benefit or for the
benefit of another, and that you will hold and treat such information as
confidential information, unless you have specific prior written authorization
from the Company to disclose it. Incorporated herein is a confidentiality and
non-competition agreement that was signed by you on or about December 10, 2001
and which remains in effect according to its terms.
