ANSI Advanced Neuromodulation Systems (MM)

St. Jude Medical, Inc. (NYSE:STJ) announced today that the previously announced subsequent offering period of its tender offer for all outstanding shares of common stock of Advanced Neuromodulation Systems, Inc. (NASDAQ:ANSI) has been extended and will now expire at 5:00 p.m. Eastern Time on Monday, November 28, 2005. The subsequent offering period was previously scheduled to expire at 12:00 midnight, Eastern Time, on Friday, November 18, 2005. Including those ANS shares tendered in the initial offering period, ANS shareholders have now tendered approximately 17,977,527 shares (up from 15,769,679 shares at the end of the initial offering period that expired on November 15, 2005), or approximately 89 percent of the outstanding shares of ANS. St. Jude Medical has accepted for payment all of the ANS shares that were validly tendered and not properly withdrawn in the offer. St. Jude Medical has also received notices of guaranteed delivery for 534,142 shares, representing approximately 2.6 percent of ANS's outstanding shares. The extension of the subsequent offering period will permit all shareholders who have not yet tendered their shares, including those shareholders who have delivered notices of guaranteed delivery but not tendered the shares underlying those notices, to obtain the $61.25 per share offer price for their ANS shares prior to consummation of a merger. If at least 90 percent of the outstanding shares of ANS common stock have been tendered by the expiration of the subsequent offering period, St. Jude Medical will carry out a "short-form" merger, as permitted by Texas law. During the subsequent offering period, ANS shares validly tendered will be accepted and promptly paid for as they are tendered. Shareholders who tender ANS shares during such period will be paid the same $61.25 net per share in cash consideration paid during the initial offering period. ANS shares tendered during the subsequent offering period may not be withdrawn. If the subsequent offering period is extended, St. Jude Medical will issue a press release prior to 9:00 a.m. Eastern Time on the first business day following the date the subsequent offering period was scheduled to expire.
