L21779AA8/USL21779AA88) issued by CSN Resources in an aggregate principal amount such that the aggregate principal amount of 2020 Notes accepted for purchase does not exceed (A) U.S.$ 350,000,000 less (B) the aggregate principal amount of 2019 Notes validly tendered and accepted for purchase pursuant to the 2019 Notes Tender Offer (the "2020 Notes Maximum Tender Amount") (the "2020 Notes Tender Offer" and, together with the 2019 Notes Tender Offer, the "Tender Offers").

Each of the Tender Offers expired at 11:59 p.m., New York City time, on March 1, 2018 (the "Expiration Date").

CSN Resources previously accepted for purchase U.S.$202,806,000 in aggregate principal amount of 2019 Notes that were validly tendered at or prior to the Early Tender Date, and paid for such early tendered 2019 Notes on February 15, 2018. According to D.F. King & Co., Inc., the tender agent and information agent (the "Tender Agent and Information Agent") for the Tender Offers, additional tenders were received (and not validly withdrawn) after 5:00 p.m., New York City time, on February 14, 2018 (the "Early Tender Date") but at or prior to the Expiration Date from holders of 2019 Notes representing approximately U.S.$100,000 in aggregate principal amount of 2019 Notes. Subject to the terms and conditions of the 2019 Notes Tender Offer, holders who validly tendered their 2019 Notes after the Early Tender Date but at or prior to the Expiration Date and whose 2019 Notes are accepted for purchase will be entitled to receive, for each U.S.$1,000 principal amount of 2019 Notes accepted for purchase, U.S.$970, plus accrued interest. Pursuant to the terms of the 2019 Notes Tender Offer, CSN Resources has accepted for purchase all such 2019 Notes validly tendered after the Early Tender Date but at or prior to the Expiration Date and will pay for such tendered 2019 Notes on March 5, 2018 (the "Final Settlement Date"). Consequently, upon the Final Settlement Date, the total amount of 2019 Notes tendered and cancelled under the 2019 Notes Tender Offer will be U.S.$202,906,000. 

As of the Expiration Date, according to the Tender Agent and Information Agent, tenders were received (and not validly withdrawn) from holders of 2020 Notes representing U.S.$521,194,000 in aggregate principal amount of 2020 Notes. Subject to the terms and conditions of the 2020 Notes Tender Offer, including the 2020 Notes Maximum Tender Amount, holders who validly tendered their 2020 Notes at or prior to the Early Tender Date and whose 2020 Notes are accepted for purchase are eligible to receive U.S.$1,000 for each U.S.$1,000 principal amount of 2020 Notes validly tendered (and not validly withdrawn), which includes an early tender payment equal to U.S.$30, plus accrued interest. Holders of 2020 Notes who validly tendered 2020 Notes after the Early Tender Date but at or prior to the Expiration Date and whose 2020 Notes are accepted for purchase will be entitled to receive, for each U.S.$1,000 principal amount of 2020 Notes accepted for purchase, U.S.$970. 

Pursuant to the terms of the 2020 Notes Tender Offer, including the 2020 Notes Maximum Tender Amount, CSN Resources has accepted for purchase U.S.$147,094,000 in aggregate principal amount of 2020 Notes and will pay for such tendered 2020 Notes, on a pro rata basis, on the Final Settlement Date. The proration ratio that will be applied to each tendering holder of 2020 Notes is equal to (i) the amount of 2020 Notes validly tendered (and not validly withdrawn) at or prior to the Expiration Date multiplied by (ii) a fraction, the numerator of which would be equal to the 2020 Notes Maximum Tender Amount and the denominator of which would be equal to the total principal amount of 2020 Notes tendered in the 2020 Notes Tender Offer, rounded downward to the nearest U.S.$1,000 principal amount.

CSN Resources intends to use the net proceeds from its offering of 7.625% senior unsecured notes due 2023, which closed on February 13, 2018, to purchase all Notes validly tendered in the Tender Offers and to pay related costs and expenses.

As a result of the above transactions, CSN has completed another step in the process of lengthening its debt maturity profile and improving liquidity as part of its strategy to readjust its capital structure.
