                                  SKILLSOFT PLC

                        SUMMARY OF DIRECTOR COMPENSATION

      No director receives any cash compensation for his services as a member of
SkillSoft's Board of Directors or any committee of the Board of Directors,
although each director is reimbursed for his expenses in attending Board of
Directors and related committee meetings. As described in the following
paragraph, non-employee directors may receive stock compensation for their
services as a member of the Board of Directors.

      On initial election to the Board of Directors, each new non-employee
director receives an option to purchase 25,000 ordinary shares under SkillSoft's
2001 Outside Director Option Plan (the "Director Plan"). Each non-employee
director who has been a director for at least six months receives an option to
purchase 10,000 ordinary shares on January 1st of each year. All options granted
under the Director Plan have a term of ten years and an exercise price equal to
fair market value of the ordinary shares on the date of grant. Each option
becomes exercisable as to 25% of the shares subject to the option on each
anniversary of the date of grant, provided the non-employee director remains a
director on such dates. Upon exercise of an option, the non-employee director
may elect to receive his ordinary shares in the form of ADSs. After termination
as a non-employee director, an optionee may exercise an option during the period
set forth in his option agreement. If termination is due to death or disability,
the option will remain exercisable for 12 months. In all other cases, the option
will remain exercisable for a period of three months. However, an option may
never be exercised later than the expiration of its ten-year term. A
non-employee director may not transfer options granted under the Director Plan
other than by will or the laws of descent and distribution. Only the
non-employee director may exercise the option during his lifetime. In the event
of SkillSoft's merger with or into another corporation or a sale of
substantially all of SkillSoft's assets, the successor corporation may assume,
or substitute a new option in place of, each option. If such assumption or
substitution occurs, the options will continue to be exercisable according to
the same terms as before the merger or sale of assets. Following such assumption
or substitution, if a non-employee director is terminated other than by
voluntary resignation, the option will become fully exercisable and generally
will remain exercisable for a period of three months. If the outstanding options
are not assumed or substituted for, the Board of Directors will notify each
non-employee director that he has the right to exercise the option as to all
shares subject to the option for a period of 30 days following the date of the
notice. The option will terminate upon the expiration of the 30-day period.
Unless terminated sooner, the Director Plan will automatically terminate in
2011. The Board of Directors has the authority to amend, alter, suspend, or
discontinue the Director Plan, but no such action may adversely affect any grant
previously made under the Director Plan.
