The Offer is being sent to you pursuant to Section 4.21 of the Indenture pursuant to which the Notes were issued because a Change of Control, as defined in the Indenture, occurred on May 25, 2006, when Tontine acquired a majority of the securities (on a fully diluted basis) of ACP Holding Company ("ACP"), the indirect parent of Neenah Foundry. Following commencement of the Original Offer, some concerns were raised regarding whether the timing of the Original Offer complied with the timing requirements of Section 4.21 of the Indenture. Although the Company believes that the timing of the Original Offer was proper under the circumstances, in response to these concerns, on July 24, 2006, the Company gave notice to Holders of the Notes of its offer to also cause Tontine to purchase Notes during a subsequent offering period beginning July 25, 2006 and extending through August 28, 2006 (the "Subsequent Offering Period"), to avoid doubt regarding the performance by the Company of its obligations under the Indenture. The deadline for tendering Notes pursuant to the Original Offer (the "Change of Control Put Date" as defined therein) is July 24, 2006. The Company promptly will comply with the Original Offer with respect to all Notes validly tendered by that date and not properly withdrawn. The Subsequent Offering Period will expire at 5:00 p.m., New York City time, on August 28, 2006, unless extended by the Company (the "Expiration Time"). Tontine will pay to each Holder, for each $1,000 principal amount of Notes validly tendered during the Subsequent Offering Period and prior to the Expiration Time and not properly withdrawn by the Expiration Time, an amount in cash equal to 101% of the aggregate principal amount of Notes tendered, plus accrued and unpaid interest to, but not including, the payment date. If the payment date is August 31, 2006, as expected, the Subsequent Offering Period Change of Control Repurchase Price will be approximately $1,031.67 per $1,000 principal amount of Notes. No tenders of Notes will be valid if submitted after the Expiration Time. HOLDERS WHO HAVE TENDERED THEIR NOTES IN THE ORIGINAL OFFER BUT WISH TO INSTEAD HAVE THEIR NOTES PURCHASED AT THE END OF THE SUBSEQUENT OFFERING PERIOD SHOULD CONTACT THE PAYING AGENT BY 5:00 P.M., NEW YORK CITY TIME, ON JULY 26, 2006.
