Item 1.01.  Entry into a Material Definitive Agreement.

         (a) On May 16, 2006, the Compensation Committee of the Board of
Directors of the Company, in conjunction with the Board of Directors (with
Messrs. Cumming and Steinberg not voting), awarded performance bonuses for 2005
of $6,826,950 to each of Ian M. Cumming and Joseph S. Steinberg, Chairman of the
Board and President, respectively, of the Company.

         Of this amount, $5,057,000 was awarded under the Company's 2003
Senior Executive Annual Incentive Bonus Plan, representing 1.0% of the Company's
audited pre-tax income for the year ended December 31, 2005, the maximum amount
awardable under the plan as in effect for fiscal year 2005. The $1,769,950
balance of the 2005 performance bonus for each of Messrs. Cumming and Steinberg
was awarded in recognition of the significant federal tax savings recognized by
the Company in 2005 attributable to tax attributes of the Company's former
subsidiary, WilTel Communications Group, LLC and for which bonus compensation
under the plan would not be paid. This additional bonus amount is equal to .35%
of the Company's audited consolidated pre-tax income for the year ended December
31, 2005. Upon receipt of shareholder approval at the Company's 2006 annual
meeting of shareholders, the Company's Senior Executive Annual Incentive Bonus
Plan has been amended to increase the maximum annual incentive bonus that may be
paid to each of Messrs. Cumming and Steinberg under the plan from 1% to 1.35% of
audited pre-tax earnings of the Company and its consolidated subsidiaries for
performance periods commencing on January 1, 2006 through 2014.

         The amount of the annual incentive bonus awarded under the plan to each
participant in any given year is subject to reduction by the Compensation
Committee, in its sole discretion. The Incentive Bonus Plan is designed so that
the cash bonuses awarded under the plan will qualify as "performance-based
compensation" under Section 162(m) of the Internal Revenue Code. However, the
additional $1,769,950 bonus awarded to Messrs. Cumming and Steinberg was outside
of the Incentive Bonus Plan and does not qualify as "performance-based
compensation" under Section 162(m) of the Internal Revenue Code.

         Following shareholder approval at the 2006 annual meeting of
shareholders, previously announced warrants to purchase 1,000,000 common shares
of the Company have been issued to each of Ian M. Cumming and Joseph S.
Steinberg on May 16, 2006, at a per exercise price of $57.03 per share,
representing 105% of the closing price of the Company's common shares as quoted
on the New York Stock Exchange on March 6, 2006, the date on which the warrants
were granted to Messrs. Cumming and Steinberg. The exercise price of the
warrants will be adjusted to give effect to the two-for-one stock split
announced by the Company on May 16, 2006, payable on June 14, 2006 to
shareholders of record on May 30, 2006.

         Also on May 16, 2006, the Board of Directors, upon the recommendation
of the Company's Audit Committee, approved an amendment to the Shareholders
Agreement among the Company, Ian M. Cumming and Joseph S. Steinberg dated June


                                       2

30, 2003 (the "Shareholders Agreement"). Under the Shareholders Agreement, the
Company has agreed to repurchase up to 55% of the interest of each of Mr.
Cumming and Mr. Steinberg in the common shares of the Company upon the death of
Mr. Cumming and Mr. Steinberg, not to exceed $50 million. Pursuant to the
amendment, in furtherance of the Company's goal of maintaining stability in the
Company's common shares upon the death of each Messrs. Cumming and Steinberg,
while providing their respective estates with liquidity, the Company will agree
to use all available proceeds from life insurance held by the Company on the
life of each of Messrs. Cumming and Steinberg, up to a maximum of $125 million,
to fulfill this purchase obligation.

         (b) On May 16, 2006, the Board of Directors made certain changes to the
fees paid to the Company's non-employee directors, effective July 1, 2006. As a
result, the annual retainer will be $50,000 (pro rated for 2006), members of the
Audit Committee will continue to receive $10,000 annually, the Chairman of the
Audit Committee will receive an annual fee of $14,000 (pro rated for 2006) and
meeting fees will be $750 ($850 if a committee chairman).
