NOTICE OF CHANGE IN ELECTION FROM REJECT TO ACCEPT

To NMT Medical, Inc.:
I previously received a copy of the offer to Exchange (dated March 27, 2001), the Cover Letter and Summary
of Terms, and an Election Form. I signed and returned the Election Form, in which I elected to reject NMT
Medical's offer to exchange options. I now wish to change that election and accept your offer to exchange
options. I understand that by signing this Notice, signing a new Election Form and delivering both documents to
Philip A. Hoffstein, I will be able to withdraw my rejection of the offer and accept the offer to exchange options
instead. I have read, understand and agree to all of the terms and conditions of the offer to exchange options.
I understand that in order to accept the offer, I must sign and deliver this Notice and a new Election Form to
Philip A. Hoffstein before 5 p.m., Boston, Massachusetts Time, on April 23, 2001, or if NMT Medical extends
the deadline to exchange options, before the extended expiration of the offer.
I further understand that NMT Medical will not exchange any conditional or partial returns of options. I have
completed and signed the following exactly as my name appears on my original Election Form.
I accept the offer to exchange options.
