Mr. C. Edward Chaplin

Summit, NJ 07901

Dear Chuck:

We are excited by the prospect of you joining the MBIA team in the key leadership position we have discussed. We are unanimous in our belief that you possess the professional skills, experience and interpersonal characteristics required to help MBIA achieve its goals. As such, we are pleased to extend to you an offer of employment under the terms and conditions outlined below:

I. Title, Department and Reporting Relationship - As Vice Chair, Chief Financial Officer and a member of the EPC, you will report directly to Gary Dunton.

II. Compensation - We have tailored a compensation program to reflect both your responsibilities as a CFO and our expectation of your future contributions to MBIA. Your compensation package will include a base salary, performance bonus, long-term incentive award and a cash sign-on, a restricted stock sign-on award and a stock option sign-on award. All payments under this letter are subject to applicable tax withholding obligations.

a) Base Salary - As a full-time employee you will earn $20,833.33 semi-monthly, which is an annualized base salary of $500,000. Future adjustments to your base salary will be a function of personal performance in your position, MBIA’s financial and operational performance and other related factors.

b) Performance Bonus Awards - Bonus awards are made at MBIA’s discretion and will be based foremost upon the Company’s financial performance and upon individual performance factors. This payment will be made in the first quarter of calendar year 2007 when bonuses are paid to employees at MBIA. Any future bonus awards are subject to individual and company performance and will be awarded relative to other executives with similar individual performance and can vary from year to year. You must be an active employee at the time bonuses are paid to receive the payment.

c) Long-term Incentive (LTI) - MBIA’s current LTI program consists of a grant of performance-based restricted shares that are subject to time vesting and growth in modified book value (‘MBV restricted stock’). Your MBV restricted stock award will vest three years after the grant date. The number of shares that vest will depend on growth in MBIA’s modified book value (MBV) over a three-year performance period. All awards are set relative to peers and are naturally affected by the company’s performance in any given year. MBIA’s LTI program is reviewed periodically and is subject to change. You are also eligible to participate in prior LTI awards as described below.

Prior LTI Awards

As a new hire, you will be integrated into previously granted and outstanding MBV cash and MBV restricted stock awards on a pro rata basis. This will allow you to receive vested MBV awards from prior grants beginning in 2007. You must be an active MBIA employee at the time of MBV award vesting in order to receive it. With respect to your 2007 payout, the target cash award is $225,000. The 2008 and 2009 payouts will be in the form of MBV restricted stock and the target shares payable are projected to be 5,000 and 7,500 shares respectively.

Your full formula annual LTI opportunity for your position ranges from 100% to 140% of annual run rate cash compensation, which consists of annual base salary and year-end cash performance bonus (excludes special one-time cash awards). Actual LTI awarded in any given year will be adjusted from formula based on company performance and individual performance for that given year. All compensation is subject to CEO and compensation committee discretion. The company also reserves the right to change its compensation program in the future. Awards under the program are approved annually by the Compensation and Organization Committee of the MBIA Inc. Board of Directors and are granted during the year-end process.

Additionally as an EPC member, you will be provided with guidance which will help you manage your long term incentive in a manner that will create a stock ownership position in MBIA. EPC members are given the goal of achieving a minimum holding position of owning MBIA stock. In your case the minimum holding target is 3 times your base salary. Kevin Silva and I would be happy to review the Company’s ownership guidelines with you.
