Effective as of the Distribution Date,(i) the MVT Deferred Compensation Plan shall assume and be solely responsible for all liabilities for or relating to MVT Employees under the MI Deferred Compensation Plans and (ii) the MI Group shall cause the accounts (including unvestedamounts) of the MVT Employees under the MI Deferred Compensation Plans and an amount equal to the fair market value of the assets attributable thereto that are held by the MI Deferred Compensation Trust II or the MI Corp. Amended and RestatedDeferred Compensation Trust III (the “MI Deferred Compensation Trusts”) as of such date to be transferred to the MVT Deferred Compensation Plan and the MVT Deferred Compensation Trust, and the MVT Group shall cause such transferredaccounts and assets to be accepted by such plan and trust. In determining the fair market value of the assets attributable to the accounts of the MVT 

Employees, there shall not be a transfer for the value of any restricted stock units of New MI Corp. for which MVT Group has not previously reimbursed MICorp. The value of the restricted stock units for which MVT Group has not previously reimbursed MI Corp will be determined based upon the proportion of the unrecovered cost to the original cost of the restricted stock units multiplied times thevalue of the unvested restricted stock units determined based on the closing share price of New MI Corp. on the date following the Distribution Date. To the extent that the fair market value of plan assets held in the MI Deferred Compensation Trustswhich are attributable to the accounts of the MVT Employees, are not sufficient to fund the liabilities relating to the MVT Employees, the MVT Group shall be responsible for such obligation, whether such underfunding is due to an overallunderfunding of the trust or is due to the unreimbursed restricted stock units. The transfer of assets shall be made in cash or in kind from the MI Deferred Compensation Trusts to the MVT Deferred Compensation Trust; provided that no shares of NewMI Corp. Common Stock shall be transferred from the MI Deferred Compensation Trusts to the MVT Deferred Compensation Trust.

Such contribution shall bemade with respect to MVT Employees who remain in the MVT Group’s employ on December 31, 2007 (or retire, die or become disabled during calendar year 2007) and who would be eligible for an allocation under the terms of the MI DeferredCompensation Plans taking into account employment with the MVT Group after the Distribution Date. Such contribution shall be made to the MVT Deferred Compensation Trust at a time to be determined by the MVT Group which is on or beforeSeptember 15, 2008. 

4.3. No Distribution to MVT Employees. No distribution of account balances shall be made toany MVT Employee from the MI Deferred Compensation Plans or the MVT Deferred Compensation Plan because of the fact that the MVT Group ceases to be affiliated with the MI Group and ceases to be a participating employer under the MI DeferredCompensation Plans. Such events shall not be treated as a termination of employment for plan purposes and distribution shall not be otherwise specifically permitted under plan terms as a result of the cessation of affiliation and of participatingemployer status.”
