INTRODUCTORY STATEMENT

On May 14, 2010, Tyco International Ltd. (“Tyco” or “the Registrant”) completed its acquisition of Brink’s Home Security Holdings, Inc. (“BHS”) pursuant to the terms of a merger agreement, dated as of January 18, 2010 (the “Merger Agreement”), by and among Tyco, BHS, Barricade Merger Sub, Inc., and, solely for the purposes stated therein, ADT Security Services, Inc.

Pursuant to the terms of the Merger Agreement, upon the effective time of the merger, (i) certain options to purchase BHS common stock, no par value (each, a “BHS Stock Option”) granted under the Brink’s Home Security Holdings, Inc. 2008 Equity Incentive Plan (the “2008 EIP”) and the Brink’s Home Security Holdings, Inc. Non-Employee Directors’ Equity Plan (the “BHS Non Employee Directors’ Plan”, and together with the 2008 EIP, the “Plans”) were converted into options (each, a “Tyco Stock Option”) to purchase a number of common shares, with a par value CHF 7.60 per share, of Tyco (the “Tyco Common Shares”), based on an exchange ratio set forth in the Merger Agreement, (ii) certain BHS restricted share units granted under the BHS Non Employee Directors’ Plan were converted into restricted share units (each, a “Tyco Restricted Share Unit”) with respect to a number of Tyco Common Shares based on an exchange ratio set forth in the Merger Agreement, and (iii) certain deferred BHS share units granted and/or held under the BHS Non-Employee Directors’ Equity Plan were converted into the right (a “Tyco Deferred Share Unit”) to receive a number of Tyco Common Shares based on an exchange ratio set forth in the Merger Agreement. This Registration Statement on Form S-8 registers the aggregate number of Tyco Common Shares issuable pursuant to such Tyco Stock Options, Tyco Restricted Share Units and Tyco Deferred Share Units and the aggregate number of Tyco Common Shares reserved for issuance and issuable under the 2008 EIP.

Item 9. Undertakings.

(a) The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by section 10(a)(3) of the Securities Act of 1933;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement;

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

Provided, however, that paragraphs (a)(1)(i) and (a)(2)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed, to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers, and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer, or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer, or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
