EXPLANATORY NOTE

This Amendment No. 1 ("Amendment No. 1") to the Annual Report on Form 20‑F of Banco Bradesco S.A. (the "Bank") for the fiscal year ended December 31, 2015 (the "Form 20‑F"), originally filed with the Securities and Exchange Commission (the "SEC") on April 18, 2016 (the "Original Report"), is being filed solely to amend Exhibit 4.1 to the Original Report ("Exhibit 4.1") and amend and restate Item 19 (Exhibits) of the Original Report accordingly.  The Bank no longer seeks confidential treatment of certain of the items for which confidential treatment was originally requested for Exhibit 4.1.  Accordingly, the Bank is refiling Exhibit 4.1 with only those portions redacted as to which it continues to request confidential treatment.

Additionally, in connection with the filing of this Amendment No. 1, the Bank is including currently updated certifications of the Bank's chief executive officer and chief financial officer pursuant to Rule 13a‑14(a) or Rule 15d‑14(a) of the Securities Exchange Act of 1934, as amended.  Because no financial statements have been included in this Amendment No. 1 and this Amendment No. 1 does not contain or amend any disclosure with respect to Items 307 and 308 of Regulation S-K, paragraphs 3, 4 and 5 of these certifications have been omitted.  In addition, because no financial statements are being filed with this Amendment No. 1, the Bank is not including certifications pursuant to Section 1350 of Chapter 63 of Title 18 of the United States Code (18 U.S.C.1350).

Other than expressly stated above, the Bank has not updated or amended the disclosures contained herein to reflect events that have occurred since the filing of the Original Report, or modified or updated the disclosures contained in the Original Report. Accordingly, this Amendment No. 1 should be read in conjunction with the Original Report and other reports furnished by the Bank to the SEC subsequent to the filing of the Original Report.
