 I.
    
    Objective
ITCs Executive Incentive Plan, hereinafter referred to as EIP is intended to reward
executive employees who significantly impact and influence ITCs productivity in proportion
to their accomplishment of specified objectives.The purpose of the plan is to ensure maximum return to ITC by encouraging greater initiative,
resourcefulness, teamwork and efficiency on the part of senior management whose performance
and responsibilities directly affect company profits.Awarding of the bonus will be based on company financial performance and by accomplishing a
set of annual objectives, determined by the Chief Executive Officer (CEO) and the Board of
Directors, typically at the beginning of the year. Bonus determinations and payouts will
take place after the financial statements have been prepared for the fiscal year.II.
    
    Determination Of The Fund
The availability of, and participants in, the fund will be set by the CEO and approved by the
Board of Directors as part of the annual budgeting process.III.
    
    Effective Date
The effective date of this program is December 30, 2007, the beginning of the plan year, and
will continue in effect until January 3, 2009, or until terminated or amended by the Board of
Directors. This plan supersedes all prior EIP plans.IV.
    
    Eligibility
Participation in the plan is limited to those in comparable levels of responsibility who have
a direct and significant influence on ITCs growth and profitability. Employees must be
regular and not eligible for any other ITC commission, bonus or incentive plan in order to be
eligible to participate in the EIP.Participating employees will be determined at the beginning of the fiscal year, or at such
time during the Fiscal Year that an employee achieves an eligible position. Employees will
be notified of their eligibility and plan objectives, as soon as possible after the
determination by the CEO or Board of Directors.Individuals must be employed by ITC at the close of the fiscal year and the date of payment
in order to be eligible for an award under the EIP except participants who are involuntarily
terminated due to a divestiture, plant closing, reorganization or reduction in force during
the plan year may receive an award on the prorated basis described in Section VIII, Plan
Administration, Prorated Awards, (subject to approval by the CEO). These monies will
be paid out at the usual and customary time of payment of all bonuses. For purposes of this
plan, termination shall mean the day the employee leaves the job, which may not necessarily
be the last day on the payroll.V.
    
    Incentive Objectives
Objectives will be agreed to by the CEO with the Senior Management reporting to him and with
concurrence by the Board of Directors as necessary. Generally, there will be a minimum of
three up to a maximum of seven objectives, which will include two or more financial
objectives. Each objective will be weighted according to its importance, which weight will
determine the percentage of the bonus awarded for completion of that objective. (See Section
VI below.)VI.
    
    Bonus Opportunity and Award
The award opportunity will be expressed as a percentage of the participants base salary at
the close of the fiscal year. The award will be approved by the Board of Directors or the
CEO, and will be consistent with the participants peers within the company.The amount that a participant actually receives for the full fiscal year will be based upon
the extent to which the set objectives have been achieved. The participant will receive a
percentage of the total award opportunity corresponding to the percentage of each objective
accomplished and the weight assigned to the objective. Evaluations of performance against
individual and financial objectives are made for the full year prior to fiscal year-end
payment.
