EXHIBIT A TO ROMEO OFFER LETTER

Vesting Period

The award will vest over a three (3) year period in equal annual installments typically beginning on the first anniversary of the award grant. Please note, if you leave the Thor family of companies for any reason, except as noted below, you forfeit all rights to any unvested units.

Tax Implication

At Vesting: Under normal federal income tax rules, an employee receiving a Restricted Stock Unit is not taxed at the time the grant is made. Instead, the employee is taxed at vesting. The amount subject to tax is the market value of the stock on the vesting date. The IRS treats this as ordinary income as of the vesting date. You may choose to consult with your tax advisor on the tax implications of your award.

At Sale: If shares received upon vesting are later sold, then any gain or loss on sale of shares (i.e. post-vesting share price appreciation/depreciation) is taxable as short- or long-term capital gain, depending on how long the stock has been held.

Paying Income Tax on Restricted Stock via Net Shares

Computershare Stock Plan Services will administer the plan, which includes an annual statement and processing income tax withholding through net shares.

Net shares is a process through which the appropriate number of shares are withheld at vesting in order to cover an employee’s tax withholding obligation. At the time of vesting, you will receive the number of shares vested less the number of shares withheld for tax purposes. This process is designed to alleviate the tax impact on the employee by avoiding or minimizing the employee’s tax liability associated with the award.

Recoupment Provision

Thor has established a recoupment provision that applies to all forms of incentive compensation paid to employees of Thor and each operating company. This policy will have a three (3) year look back period during which any incentive compensation that was paid within that three (3) year period that was based on what are subsequently determined to be erroneous financial statements specific to Thor, must be repaid to Thor if and only if (1) the erroneous financial statements of Thor were, in whole or in part, the basis for the incentive compensation that was paid and (2) the erroneous financial statements resulted in an amount of incentive compensation being paid to a recipient that would not have been payable if the financial statements had not been erroneous. Under this policy, only the portion of incentive compensation which is subsequently determined to have been paid based upon an error in the financial statements will be subject to the repayment obligations of the policy.

Dividends

Dividends will not be earned on unvested shares. However, once the shares vest and are issued to you, dividends will be paid as announced by the Company from time to time.

Retirement Eligibility

In the event you are planning to retire, Thor’s Compensation and Development Committee will address unvested restricted units and provide you additional details.
