This Amendment No. 1 (“ Amendment No.  1 ”) amends and supplements the Tender Offer Statement on Schedule TO (together with any subsequent amendments and supplements thereto, the “ Schedule TO ”) filed with the Securities and Exchange Commission on November 21, 2018, relating to the offer by Host Merger Sub Inc., a Delaware corporation (“ Purchaser ”) and a wholly owned subsidiary of BBX Inc., a Delaware corporation (“ BBX Intermediate ”) and a wholly owned subsidiary of BBX Main Inc., a Delaware corporation (“ Parent ”) and a wholly owned subsidiary of AGC Networks Pte Ltd., a private limited liability company organized and existing under the laws of Singapore (“ AGC Networks ,” and collectively with Purchaser, BBX Intermediate and Parent, the “ Parent Entities ”), to purchase any and all issued and outstanding shares of common stock, $0.001 par value per share, of Black Box Corporation, a Delaware corporation (“ Black Box ” or the “ Company ”), at a price of $1.08 per Share, net to the seller in cash, without interest thereon and subject to any applicable withholding taxes, upon the terms and subject to the conditions set forth in the Offer to Purchase, dated November 21, 2018 (incorporated by reference in the Schedule TO as Exhibit (a)(1)(A)), as amended or supplemented from time to time, and in the related Letter of Transmittal (incorporated by reference in the Schedule TO as Exhibit (a)(1)(B)), as amended or supplemented from time to time.

Except to the extent amended and supplemented by this Amendment No. 1, the information in the Schedule TO remains unchanged. Capitalized terms used, but not otherwise defined, in this Amendment No. 1 have the meanings ascribed to them in the Schedule TO.

Section 15—“Certain Legal Matters; Regulatory Approvals” of the Offer to Purchase is hereby amended and supplemented by adding the following text as new paragraphs at the end of the section under a new sub-heading “Litigation” under Section 15.

Litigation . On November 29, 2018, a purported stockholder filed a putative class action lawsuit in the Court of Common Pleas of Washington County, Pennsylvania, captioned Michael Wood v. Black Box Corporation, et al. , Case No. 2018-6696 (PA Washington CT. C.P.) (the “ Wood Complaint ”). The Wood Complaint names the Company and the Company’s Board of Directors (the “ Company Board ”) as defendants. The Wood Complaint alleges that the Company Board violated fiduciary duties owed to the Company’s public shareholders, by, among other things, purportedly failing to obtain for the Company’s stockholders the highest value available for the Company in the marketplace. The Wood Complaint seeks, among other things, to enjoin the Merger Agreement and the Offer unless or until the Company adopts and implements a procedure or process to obtain the highest possible value in the best interests of the Company’ stockholders, or, alternatively, to recover damages if the Offer is consummated prior to the entry of the court’s final judgment. The Company has advised us that it believes that the action is without merit.

Also on November 29, 2018, a purported stockholder filed a putative class action lawsuit in the United States District Court for the District of Delaware, captioned Adam Franchi v. Black Box Corporation, et al. , Case No. 1:18-cv-01890 (D. Del.) (the “ Franchi Complaint ”). The Franchi Complaint names the Company, the Company Board, and the Parent Entities as defendants. The Franchi Complaint alleges that the defendants violated federal securities laws by filing, or causing the Company to file, a Schedule 14D-9 Solicitation/Recommendation Statement in connection with the Transactions that omits purportedly material information. The Franchi Complaint seeks, among other things, to enjoin the closing of the Transactions or, alternatively, to recover damages if the Transactions close. The Company has advised us that it believes, and we believe, that the action is without merit.

On November 30, 2018, a purported stockholder filed a putative class action lawsuit in the United States District Court for the Central District of California, captioned James Adie v. Black Box Corporation, et al. , Case No. 5:18-cv-02537 (C.D Cal.) (the “ Adie Complaint ”). The Adie Complaint names the Company and the Company Board as defendants. The Adie Complaint alleges that the defendants violated federal securities laws by filing, or causing the Company to file, a Schedule 14D-9 Solicitation/Recommendation Statement in connection with the Offer that omits purportedly material information. The Adie Complaint seeks, among other things, to enjoin the closing of the Offer unless and until the requested information is disclosed or, alternatively, to recover damages. The Company has advised us that it believes that the action is without merit.

If additional similar complaints are filed, absent new or different allegations that are material, we and the Company will not necessarily announce such additional filings.

Clause 2(e) of Section 13—“Conditions of the Offer” of the Offer to Purchase is hereby amended and restated in its entirety as follows: “The Merger Agreement has been terminated in accordance with its terms; or.”
