 Dear Dick: 
  
 This letter is to acknowledge that your last day with MBIA as a regular

 You will be entitled to receive any vested benefits to which you are entitled under MBIA’s Retirement Plans as of your Separation Date. Such vested benefits will be paid to you pursuant to the terms of the

 Your medical and dental, life and short and long-term disability insurance ends as of June 30, 2004. If you choose, you may
elect to receive retiree medical and dental coverage. You will also be eligible to convert your life insurance coverage to an individual policy. You will not be eligible to participate in MBIA’s Retirement Plans past the separation date except
to the extent of any vested rights therein. 
  
 Whether or not you
sign the attached Agreement and General Release (the “Agreement”), you will be entitled to the benefits referred to in the previous paragraphs and you may elect retiree medical and dental benefit continuation coverage. 
  
 Further, we are offering the following additional payments and benefits as
