DESCRIPTION OF DEBT SECURITIES
AND GUARANTEE OF DEBT SECURITIES

The following is a general description of the debt securities that we may offer from time to time. The particular terms of the debt securities offered by any prospectus supplement and the extent, if any, to which the general provisions described below may apply to those securities will be described in the applicable prospectus supplement. We also may sell hybrid securities that combine certain features of debt securities and other securities described in this prospectus. As you read this section, please remember that the specific terms of a debt security as described in the applicable prospectus supplement will supplement and may modify or replace the general terms described in this section. If there are any differences between the applicable prospectus supplement and this prospectus, the applicable prospectus supplement will control. As a result, the statements we make in this section may not apply to the debt security you purchase.

Tyco International Finance S.A., or TIFSA, is the issuer of the applicable series of debt securities and references to TIFSA in this description do not, unless the context otherwise indicates, include any of its respective subsidiaries. References to Tyco International in this description refer to Tyco International Ltd., not including its combined subsidiaries. Capitalized terms used but not defined in this section have the respective meanings set forth in the applicable indenture.

General

The debt securities that we offer will be either senior debt securities or subordinated debt securities. TIFSA will issue senior debt securities under the Senior Debt Indenture, dated January 9, 2009, between TIFSA and Deutsche Bank Trust Company Americas, as trustee. TIFSA will issue subordinated debt securities under a different indenture, which we refer to as the subordinated indenture, to be entered into between TIFSA and the trustee named in the applicable prospectus supplement. We refer to both the senior indenture and the subordinated indenture as the indentures, and to each of the trustees under the indentures as a trustee. In addition, the indentures may be supplemented or amended as necessary to set forth the terms of the debt securities issued under the indentures. You should read the indentures, including any amendments or supplements, carefully to fully understand the terms of the debt securities. The forms of the indentures have been filed as exhibits to the registration statement of which this prospectus is a part. The indentures are subject to, and are governed by, the Trust Indenture Act of 1939, as amended.

The senior debt securities will be unsubordinated obligations of TIFSA. They will rank equally with each other and all of TIFSA's other unsubordinated debt, unless otherwise indicated in the applicable prospectus supplement. The subordinated debt securities will be subordinated in right of payment to the prior payment in full of TIFSA's senior debt. See "Subordination of Subordinated Debt Securities." The subordinated debt securities will rank equally with each other, unless otherwise indicated in the applicable prospectus supplement. We will indicate in each applicable prospectus supplement, as of the most recent practicable date, the aggregate amount of TIFSA's outstanding debt that would rank senior to the subordinated debt securities.

Debt securities issued by TIFSA will be fully and unconditionally guaranteed by Tyco International. The debt securities will not be guaranteed by, and therefore will not constitute obligations of, TIFSA's subsidiaries. Creditors of TIFSA's subsidiaries are entitled to a claim on the assets of those subsidiaries. Consequently, in the event of a liquidation or reorganization of any subsidiary, creditors of a subsidiary are likely to be paid in full before any distribution is made to TIFSA and holders of its debt securities, except to the extent that TIFSA is itself recognized as a creditor of that subsidiary, in which case TIFSA's claims would still be subordinate to any security interests in the assets of the subsidiary and any debt of the subsidiary senior to that held by TIFSA.

Table of Contents

The indentures do not limit the amount of debt securities that can be issued thereunder and provide that debt securities of any series may be issued thereunder up to the aggregate principal amount that we may authorize from time to time. Unless otherwise provided in the applicable prospectus supplement, the indentures do not limit the amount of other indebtedness or securities that we may issue. We may issue debt securities of the same series at more than one time and, unless prohibited by the terms of the series, we may reopen a series for issuances of additional debt securities without the consent of the holders of the outstanding debt securities of that series. All debt securities issued as a series, including those issued pursuant to any reopening of a series, will vote together as a single class.

Reference is made to the prospectus supplement for the following and other possible terms of each series of the debt securities in respect of which this prospectus is being delivered:

•: the title of the debt securities;
•: any limit upon the aggregate principal amount of the debt securities of that series that may be authenticated and delivered under the applicable indenture, except for debt securities authenticated and delivered upon registration of transfer of, or in exchange for or in lieu of, other debt securities of that series;

•: the form of the debt securities of the series including the form of the trustee's certificate of authentication for such series;

Table of Contents

•: if the principal amount payable at the stated maturity of debt securities of the series will not be determinable as of any one or more dates prior to such stated maturity, the amount which will be deemed to be such principal amount as of any such date for any purpose, including the principal amount thereof that will be due and payable upon declaration of the maturity thereof or upon any maturity other than the stated maturity or that will be deemed to be outstanding as of any such date, or, in any such case, the manner in which such deemed principal amount is to be determined;
•: the terms of any repurchase or remarketing rights;
•: if the securities of the series shall be issued in whole or in part in the form of a global security or securities, the type of global security to be issued; the terms and conditions, if different from those contained in the applicable indenture, upon which such global security or securities may be exchanged in whole or in part for other individual securities in definitive registered form; the depositary for such global security or securities; and the form of any legend or legends to be borne by any such global security or securities in addition to or in lieu of the legends referred to in the indenture;
•: whether the debt securities of the series will be convertible into or exchangeable for other debt securities, registered shares or other securities of any kind of Tyco International or another obligor, and, if so, the terms and conditions upon which such debt securities will be so convertible or exchangeable, including the initial conversion or exchange price or rate or the method of calculation, how and when the conversion price or exchange ratio may be adjusted, whether conversion or exchange is mandatory, at the option of the holder or at TIFSA's option, the conversion or exchange period, and any other provision in addition to or in lieu of those described herein;
•: any additional restrictive covenants or events of default that will apply to the debt securities of the series, or any changes to the restrictive covenants set forth in the applicable indenture that will apply to the debt securities of the series, which may consist of establishing different terms or provisions from those set forth in the applicable indenture or eliminating any such restrictive covenant or event of default with respect to the debt securities of the series;
•: any provisions granting special rights to holders when a specified event occurs;
•: if the amount of principal or any premium or interest on debt securities of a series may be determined with reference to an index or pursuant to a formula, the manner in which such amounts will be determined;
•: any special tax implications of the debt securities, including provisions for original issue discount securities, if offered;
•: whether and upon what terms debt securities of a series may be defeased if different from the provisions set forth in the applicable indenture;

Table of Contents

regulations, including the Securities Act and the rules and regulations promulgated thereunder, or advisable in connection with the marketing of debt securities of that series.

We will comply with Section 14(e) under the Exchange Act, to the extent applicable, and any other tender offer rules under the Exchange Act that may then be applicable, in connection with any obligation to purchase debt securities at the option of the holders thereof. Any such obligation applicable to a series of debt securities will be described in the prospectus supplement relating thereto.

Unless otherwise described in a prospectus supplement relating to any debt securities, there are no covenants or provisions contained in the indentures that may afford the holders of debt securities protection in the event that we enter into a highly leveraged transaction.

The statements made hereunder relating to the indentures and the debt securities are summaries of certain provisions thereof and are qualified in their entirety by reference to all provisions of the indentures and the debt securities and the descriptions thereof, if different, in the applicable prospectus supplement.

Subordination of Subordinated Debt Securities

TIFSA will set forth in the applicable prospectus supplement the terms and conditions, if any, upon which any series of subordinated debt securities is subordinated to debt securities of another series or to TIFSA's other indebtedness. The terms will include a description of:

•: the indebtedness ranking senior to the debt securities being offered;
•: the restrictions, if any, on payments to the holders of the debt securities being offered while a default with respect to the senior indebtedness is continuing; and
•: the provisions requiring holders of the debt securities being offered to remit some payments to the holders of senior indebtedness.

Tyco Guarantee

Tyco International will unconditionally guarantee the due and punctual payment of the principal of, premium, if any, and interest on any debt securities issued by TIFSA, when and as the same shall become due and payable, whether at maturity, upon redemption, by acceleration or otherwise. A guarantee of subordinated debt securities will be subordinated to the other obligations of Tyco International. The guarantee provides that in the event of a default in payment on a debt security, the holder of the debt security may institute legal proceedings directly against Tyco International to enforce the guarantee without first proceeding against TIFSA.

Redemption at TIFSA's Option

If specified in the applicable prospectus supplement, TIFSA may redeem the debt securities of any series, as a whole or in part, at TIFSA's option on and after the dates and in accordance with the terms established for such series, if any, in the applicable prospectus supplement. If TIFSA redeems the debt securities of any series, TIFSA also must pay accrued and unpaid interest, if any, to the date of redemption on such debt securities.

Redemption Upon Changes in Withholding Taxes

TIFSA may redeem all, but not less than all, of the debt securities of any series under the following conditions:

•: If there is an amendment to, or change in, the laws or regulations of Luxembourg, Switzerland or the United States, as applicable, or any political subdivision thereof or therein having the

Table of Contents

power to tax (a "Taxing Jurisdiction"), or any change in the application or official interpretation of such laws, including any action taken by a taxing authority or a holding by a court of competent jurisdiction, regardless of whether such action or such holding is with respect to TIFSA or Tyco International;

•

As a result of such amendment or change, TIFSA or Tyco International becomes, or there is a material probability that TIFSA or Tyco International will become, obligated to pay Additional Amounts, as defined below in "Payment of Additional Amounts," on the next payment date with respect to the debt securities of such series;

•

The obligation to pay Additional Amounts cannot be avoided through TIFSA's or Tyco International's commercially reasonable measures;

•

TIFSA delivers to the trustee:

•: a certificate of TIFSA or Tyco International, as the case may be, stating that the obligation to pay Additional Amounts cannot be avoided by TIFSA or Tyco International, as the case may be, taking commercially reasonable measures available to it; and
•: a written opinion of independent legal counsel to TIFSA or Tyco International, as the case may be, of recognized standing to the effect that TIFSA or Tyco International, as the case may be, has, or there is a material probability that it will become obligated, to pay Additional Amounts as a result of a change, amendment, official interpretation or application described above and that TIFSA or Tyco International, as the case may be, cannot avoid the payment of such Additional Amounts by taking commercially reasonable measures available to it; and

•

Following the delivery of the certificate and opinion described in the previous bullet point, TIFSA provides notice of redemption not less than 30 days, but not more than 90 days, prior to the date of redemption. The notice of redemption cannot be given more than 90 days before the earliest date on which TIFSA or Tyco International would be otherwise required to pay Additional Amounts, and the obligation to pay Additional Amounts must still be in effect when the notice is given.

Upon the occurrence of each of the bullet points above, TIFSA may redeem the debt securities of such series at a redemption price equal to 100% of the principal amount thereof, together with accrued and unpaid interest, if any, to the redemption date.

Notice of Redemption

Notice of any redemption will be mailed at least 30 days but not more than 90 days before the redemption date to each holder of debt securities of a series to be redeemed. If TIFSA elects to redeem a portion but not all of such debt securities, the trustee will select the debt securities to be redeemed in accordance with a method determined by TIFSA, in such manner as complies with applicable legal and stock exchange requirements, if any.

Interest on such debt securities or portions of debt securities will cease to accrue on and after the date fixed for redemption, unless TIFSA defaults in the payment of such redemption price and accrued interest with respect to any such security or portion thereof.

If any date of redemption of any security is not a business day, then payment of principal and interest may be made on the next succeeding business day with the same force and effect as if made on the nominal date of redemption and no interest will accrue for the period after such nominal date.

Table of Contents

Payment of Additional Amounts

Unless otherwise required by law, neither TIFSA nor Tyco International will deduct or withhold from payments made by TIFSA or Tyco International under or with respect to the debt securities and the guarantees on account of any present or future taxes, duties, levies, imposts, assessments or governmental charges of whatever nature imposed or levied by or on behalf of any Taxing Jurisdiction ("Taxes"). In the event that TIFSA or Tyco International is required to withhold or deduct any amount for or on account of any Taxes from any payment made under or with respect to any debt securities or guarantee, as the case may be, TIFSA or Tyco International, as the case may be, will pay such additional amounts ("Additional Amounts") so that the net amount received by each holder of debt securities (including Additional Amounts) after such withholding or deduction will equal the amount that such holder would have received if such Taxes had not been required to be withheld or deducted.

Additional Amounts will not be payable with respect to a payment made to a holder of debt securities or a holder of beneficial interests in global securities where such holder is subject to taxation on such payment by a relevant Taxing Jurisdiction for any reason other than such holder's mere ownership of the securities or for or on account of:

•

any Taxes that are imposed or withheld solely because such holder or a fiduciary, settlor, beneficiary, or member of such holder if such holder is an estate, trust, partnership, limited liability company or other fiscally transparent entity, or a person holding a power over an estate or trust administered by a fiduciary holder:

Events of Default

With respect to debt securities of a particular series, an "Event of Default" means any one or more of the following events that has occurred and is continuing, except with respect to any series of securities for which the supplemental indenture or resolution of the board of directors under which such series of securities is issued or the form of security for such series expressly provides that any such Event of Default shall not apply to such series of securities:

•: the guarantee with respect to the securities of such series shall for any reason cease to be, or shall for any reason be asserted in writing by Tyco International or TIFSA not to be, in full force and effect and enforceable in accordance with its terms except to the extent contemplated by the indenture and such guarantee;
•: a court having jurisdiction in the premises shall enter a decree or order for relief in respect of TIFSA or Tyco International in an involuntary case under any applicable bankruptcy, insolvency or other similar law now or hereafter in effect, or appointing a receiver, liquidator, assignee, custodian, trustee or sequestrator or similar official of TIFSA or Tyco International or for any substantial part of its property or ordering the winding up or liquidation of its affairs, and such decree or order shall remain unstayed and in effect for a period of 90 consecutive days;

•: any other Event of Default provided in the supplemental indenture or resolution of the board of directors under which such series of securities is issued or in the form of security for such series.

If an Event of Default shall have occurred and be continuing in respect of the securities of a series, in each and every case, unless the principal of all the securities of the series shall have already become due and payable, either the trustee or the holders of not less than 25% in aggregate principal amount of the securities of such series then outstanding, by notice in writing to Tyco International and TIFSA, and to the trustee if given by such holders, may declare the unpaid principal of all the securities of that series to be due and payable immediately.

The holders of a majority in aggregate principal amount of securities of any series, by written notice to Tyco International and TIFSA and the trustee, may waive any existing default in the performance of any of the covenants contained in the indenture or established with respect to such series and its consequences, except a default in the payment of the principal of, premium, if any, or interest on, any of the securities of that series as and when the same shall become due by the terms of such securities. Upon any such waiver, the default covered thereby and any Event of Default arising therefrom shall be deemed to be cured for all purposes of the indenture.

The holders of a majority in aggregate principal amount of the outstanding securities of any series shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee with respect to such series; provided, however, that such direction shall not be in conflict with any rule of law or with the indenture or be unduly prejudicial to the rights of holders of securities of any other outstanding series of debt securities. Subject to the terms of the indenture, the trustee shall have the right to decline to follow any such direction if the trustee in good faith, by a responsible officer or responsible officers of the trustee, shall determine that the proceeding so directed would involve the trustee in personal liability.

Table of Contents

No holder of any security of any series shall have any right to institute any suit, action or proceeding in equity or at law under the indenture or to appoint a receiver or trustee, or to seek any other remedies under the indenture unless:

•: such holder previously shall have given to the trustee written notice of an Event of Default and the continuance thereof specifying such Event of Default;

•: during such 60 day period, the holders of a majority in principal amount of the securities of that series do not give the trustee a direction inconsistent with such request.

The right of any holder to receive payment of principal of, and premium, if any, and interest on such security or to institute suit for the enforcement of any such payment shall not be impaired or affected without the consent of such holder.

Modification of the Indenture

TIFSA, Tyco International and the trustee may from time to time and at any time enter into an indenture or indentures supplemental to the indenture without the consent of any holders of any series of securities for one or more of the following purposes:

•: to cure any ambiguity, defect or inconsistency in the indenture or debt securities of any series, including making any such changes as are required for the indenture to comply with the Trust Indenture Act;
•: to add an additional obligor on the debt securities or to evidence the succession of another person to Tyco International or TIFSA, or successive successions, and the assumption by the successor person of the covenants, agreements and obligations of Tyco International or TIFSA, as the case may be, pursuant to provisions in the indenture concerning consolidation, merger, the sale of assets or successor entities;
•: to provide for uncertificated debt securities in addition to or in place of certificated debt securities;

•: to change or eliminate any of the provisions of the indenture, provided that any such change or elimination shall not become effective with respect to any outstanding debt security of any series created prior to the execution of such supplemental indenture which is entitled to the benefit of such provision;
•: to secure the debt securities of any series;

Table of Contents

•: to make any other change that does not adversely affect the rights of any holder of outstanding debt securities in any material respect;
•: to provide for the issuance of and establish the form and terms and conditions of a series of debt securities, to provide which, if any, of the covenants of TIFSA shall apply to such series, to provide which of the Events of Default it shall apply to such series, to provide for the terms and conditions upon which the guarantee by Tyco International of such series may be released or terminated, or to define the rights of the holders of such series of debt securities;
•: to issue additional debt securities of any series; provided that such additional debt securities have the same terms as, and be deemed part of the same series as, the applicable series of debt securities to the extent required under the indenture; or
•: to evidence and provide for the acceptance of appointment by a successor trustee with respect to the debt securities of one or more series and to add to or change any of the provisions of the indenture as shall be necessary to provide for or facilitate the administration of the trust by more than one trustee.

In addition, under the indenture, with the written consent of the holders of not less than a majority in aggregate principal amount of the debt securities of each series at the time outstanding that is affected, Tyco International and TIFSA, when authorized by board resolutions, and the trustee, from time to time and at any time may enter into an indenture or indentures to supplement the indenture. However, the following changes may only be made with the consent of each holder of outstanding debt securities affected:

It will not be necessary for the consent of the holders to approve the particular form of any proposed supplement, amendment or waiver, but it shall be sufficient if such consent approves the substance of it.

Table of Contents

Information Concerning the Trustee

In case an Event of Default with respect to the securities of a series has occurred (that has not been cured or waived), the trustee shall exercise with respect to securities of that series such of the rights and powers vested in it by the indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of his or her own affairs. None of the provisions contained in the indenture shall require the trustee to expend or risk its own funds or otherwise incur personal financial liability in the performance of any of its duties or in the exercise of any of its rights or powers, if there is reasonable ground for believing that the repayment of such funds or liability is not reasonably assured to it under the terms of the indenture or adequate indemnity against such risk is not reasonably assured to it.

The trustee may resign with respect to one or more series of debt securities by giving a written notice to TIFSA and to the holders of that series of debt securities. The holders of a majority in principal amount of the outstanding debt securities of a particular series may remove the trustee by notifying TIFSA and the trustee. TIFSA may remove the trustee if:

•: the trustee has or acquires a "conflicting interest," within the meaning of Section 310(b) of the Trust Indenture Act, and fails to comply with the provisions of Section 310(b) of the Trust Indenture Act;
•: the trustee fails to comply with the eligibility requirements provided in the indenture and fails to resign after written request therefor by TIFSA or by any such holder in accordance with the indenture; or
•: the trustee becomes incapable of acting, or is adjudged to be bankrupt or insolvent, or commences a voluntary bankruptcy proceeding, or a receiver of the trustee or of its property is appointed or consented to, or any public officer takes charge or control of the trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation.

If the trustee resigns or is removed or if the office of the trustee is otherwise vacant, TIFSA will appoint a successor trustee in accordance with the provisions of the indenture.

A resignation or removal of the trustee and appointment of a successor trustee shall become effective only upon the successor trustee's acceptance of the appointment as provided in the indenture.

Payment and Paying Agents

The interest installment on any security that is payable, and is punctually paid or duly provided for, on the fixed date on which an installment of interest with respect to securities of that series is due and payable, shall be paid to the person in whose name such security (or one or more predecessor securities) is registered at the close of business on the regular record date for such interest installment.

TIFSA, upon notice to the trustee, may appoint one or more paying agents, other than the trustee, for all or any series of the debt securities. The debt securities of a particular series will be surrendered for payment at the office of the paying agents designated by TIFSA. If TIFSA does not designate such an office, the corporate trust office of the trustee will serve as the office of the paying agent for such series. TIFSA or any of its subsidiaries may act as paying agent upon written notice to the trustee.

All funds paid by Tyco International or TIFSA to a paying agent or the trustee for the payment of the principal of, premium, if any, or interest on the debt securities which remains unclaimed for at least one year after such principal, premium, if any, or interest has become due and payable will be repaid to Tyco International or TIFSA, as the case may be, and the holder of the debt securities thereafter may look only to Tyco International and TIFSA for payment thereof.

Covenant Defeasance

Upon compliance with specified conditions, TIFSA and Tyco International will not be required to comply with some covenants contained in the indenture and the supplemental indenture, and any omission to comply with the obligations will not constitute a default or Event of Default relating to the applicable series of debt securities, or, if applicable, TIFSA's and Tyco International's obligations with respect to the applicable series of debt securities will be discharged. These conditions are:

•: Tyco International or TIFSA irrevocably deposits in trust with the trustee or, at the option of the trustee, with a trustee satisfactory to the trustee and Tyco International or the TIFSA, as the

Table of Contents

case may be, under the terms of an irrevocable trust agreement in form and substance satisfactory to the trustee, funds or governmental obligations or a combination thereof sufficient to pay principal of, premium, if any, and interest on the outstanding securities of such series to maturity or redemption, as the case may be, and to pay all other amounts payable by it hereunder, provided that (A) the trustee of the irrevocable trust shall have been irrevocably instructed to pay such funds or the proceeds of such governmental obligations to the trustee and (B) the trustee shall have been irrevocably instructed to apply such funds or the proceeds of such governmental obligations to the payment of principal, premium, if any, and interest with respect to the securities of such series;

•: such defeasance or covenant defeasance shall not (i) cause the trustee to have a conflicting interest for purposes of the Trust Indenture Act with respect to any securities or (ii) result in the trust arising from such deposit to constitute, unless it is registered as such, a regulated investment company under the Investment Company Act of 1940; and
•: such defeasance or covenant defeasance shall be effected in compliance with any additional or substitute terms, conditions or limitations which may be imposed on Tyco International or TIFSA pursuant to the indenture.

Book-Entry, Delivery and Form

The debt securities of a series may be issued in whole or in part in the form of one or more global securities that will be deposited with, or on behalf of, a depository (a "Debt Depository") identified in the applicable prospectus supplement. Global securities may be issued in either registered or bearer form and in either temporary or permanent form. Unless otherwise provided in such prospectus supplement, debt securities that are represented by a global security will be issued in denominations of $1,000 or any integral multiple thereof and will be issued in registered form only, without coupons.

We anticipate that any global securities will be deposited with, or on behalf of, The Depository Trust Company ("DTC"), and that such global securities will be registered in the name of Cede & Co., DTC's nominee. We further anticipate that the following provisions will apply to the depository arrangements with respect to any such global securities. Any additional or differing terms of the depository arrangements will be described in the prospectus supplement relating to a particular series of debt securities issued in the form of global securities.

Beneficial interests in the global securities will be represented through book-entry accounts of financial institutions acting on behalf of beneficial owners as direct or indirect participants in DTC.

Table of Contents

Investors may elect to hold their interests in the global securities through either DTC (in the United States) or (in Europe) through Clearstream or through Euroclear. Investors may hold their interests in the global securities directly if they are participants of such systems, or indirectly through organizations that are participants in these systems. Clearstream and Euroclear will hold interests on behalf of their participants through customers' securities accounts in Clearstream's and Euroclear's names on the books of their respective U.S. depositaries, which in turn will hold these interests in customers' securities accounts in the depositaries' names on the books of DTC. Beneficial interests in the global securities will be held in denominations of $1,000 and multiples of $1,000 in excess thereof. Except as set forth below, the global securities may be transferred, in whole and not in part, only to another nominee of DTC or to a successor of DTC or its nominee.

Debt securities represented by a global security can be exchanged for definitive securities in registered form only if:

•: DTC notifies us that it is unwilling or unable to continue as depositary for that global security and TIFSA does not appoint a successor depositary within 90 days after receiving that notice;
•: at any time DTC ceases to be a clearing agency registered or in good standing under the Securities Exchange Act of 1934, as amended, or other applicable statute or regulation and TIFSA does not appoint a successor depositary within 90 days after becoming aware that DTC has ceased to be registered as a clearing agency; or
•: TIFSA determines that that global security will be exchangeable for definitive securities in registered form and notifies the trustee of its decision.

A global security that can be exchanged as described in the preceding sentence will be exchanged for definitive securities issued in authorized denominations in registered form for the same aggregate amount. The definitive securities will be registered in the names of the owners of the beneficial interests in the global security as directed by DTC.

We will make principal and interest payments on all debt securities represented by a global security to the paying agent which in turn will make payment to DTC or its nominee, as the case may be, as the sole registered owner and the sole holder of the debt securities represented by a global security for all purposes under the indenture. Accordingly, we, the trustee and any paying agent will have no responsibility or liability for:

•: any aspect of DTC' s records relating to, or payments made on account of, beneficial ownership interests in a debt security represented by a global security;
•: any other aspect of the relationship between DTC and its participants or the relationship between those participants and the owners of beneficial interests in a global security held through those participants; or the maintenance, supervision or review of any of DTC' s records relating to those beneficial ownership interests.

DTC has advised us that its current practice is to credit participants' accounts on each payment date with payments in amounts proportionate to their respective beneficial interests in the principal amount of such global security as shown on DTC's records, upon DTC's receipt of funds and corresponding detail information. The underwriters or agents for the debt securities represented by a global security will initially designate the accounts to be credited. Payments by participants to owners of beneficial interests in a global security will be governed by standing instructions and customary practices, as is the case with securities held for customer accounts registered in "street name," and will be the sole responsibility of those participants. Book-entry notes may be more difficult to pledge because of the lack of a physical note.

DTC

So long as DTC or its nominee is the registered owner of a global security, DTC or its nominee, as the case may be, will be considered the sole owner and holder of the debt securities represented by that global security for all purposes of the debt securities. Owners of beneficial interests in the debt securities will not be entitled to have debt securities registered in their names, will not receive or be entitled to receive physical delivery of the debt securities in definitive form and will not be considered owners or holders of debt securities under the indenture. Accordingly, each person owning a beneficial interest in a global security must rely on the procedures of DTC and, if that person is not a DTC participant, on the procedures of the participant through which that person owns its interest, to exercise any rights of a holder of debt securities. The laws of some jurisdictions require that certain purchasers of securities take physical delivery of the securities in certificated form. These laws may impair the ability to transfer beneficial interests in a global security. Beneficial owners may experience delays in receiving distributions on their debt securities since distributions will initially be made to DTC and must then be transferred through the chain of intermediaries to the beneficial owner's account.

We understand that, under existing industry practices, if we request holders to take any action, or if an owner of a beneficial interest in a global security desires to take any action which a holder is entitled to take under the indenture, then DTC would authorize the participants holding the relevant beneficial interests to take that action and those participants would authorize the beneficial owners owning through such participants to take that action or would otherwise act upon the instructions of beneficial owners owning through them.

Beneficial interests in a global security will be shown on, and transfers of those ownership interests will be effected only through, records maintained by DTC and its participants for that global security. The conveyance of notices and other communications by DTC to its participants and by its participants to owners of beneficial interests in the debt securities will be governed by arrangements among them, subject to any statutory or regulatory requirements in effect.

DTC has advised us that it is a limited-purpose trust company organized under the New York Banking Law, a "banking organization" within the meaning of the New York Banking Law, a member of the Federal Reserve System, a "clearing corporation" within the meaning of the New York Uniform Commercial Code and a "clearing agency" registered under the Exchange Act.

DTC holds the securities of its participants and facilitates the clearance and settlement of securities transactions among its participants in such securities through electronic book-entry changes in accounts of its participants. The electronic book-entry system eliminates the need for physical certificates. DTC's participants include securities brokers and dealers, including underwriters, banks, trust companies, clearing corporations and certain other organizations, some of which, and/or their representatives, own DTC. Banks, brokers, dealers, trust companies and others that clear through or maintain a custodial relationship with a participant, either directly or indirectly, also have access to DTC's book-entry system. The rules applicable to DTC and its participants are on file with the SEC.

DTC has advised us that the above information with respect to DTC has been provided to its participants and other members of the financial community for informational purposes only and is not intended to serve as a representation, warranty or contract modification of any kind.

Clearstream

Clearstream has advised us that it is incorporated under the laws of Luxembourg as a professional depositary. Clearstream holds securities for its participating organizations, or Clearstream Participants, and facilitates the clearance and settlement of securities transactions between Clearstream Participants through electronic book-entry changes in accounts of Clearstream Participants, thereby eliminating the need for physical movement of certificates. Clearstream provides to Clearstream Participants, among

Table of Contents

other things, services for safekeeping, administration, clearance and settlement of internationally traded securities and securities lending and borrowing. Clearstream interfaces with domestic securities markets in several countries. As a professional depositary, Clearstream is subject to regulation by the Luxembourg Commission for the Supervision of the Financial Sector (Commission de Surveillance du Secteur Financier). Clearstream Participants are recognized financial institutions around the world, including underwriters, securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. Clearstream's U.S. Participants are limited to securities brokers and dealers and banks. Indirect access to Clearstream is also available to others, such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a Clearstream Participant either directly or indirectly.

Distributions with respect to debt securities held beneficially through Clearstream will be credited to cash accounts of Clearstream Participants in accordance with its rules and procedures, to the extent received by the U.S. Depositary for Clearstream.

Euroclear

Euroclear has advised us that it was created in 1968 to hold securities for participants of Euroclear, or Euroclear Participants, and to clear and settle transactions between Euroclear Participants through simultaneous electronic book-entry delivery against payment, thereby eliminating the need for physical movement of certificates and any risk from lack of simultaneous transfers of securities and cash. Euroclear performs various other services, including securities lending and borrowing and interacts with domestic markets in several countries. Euroclear is operated by Euroclear Bank S.A/N.V., or the Euroclear Operator, under contract with Euroclear plc, a U.K. corporation. All operations are conducted by the Euroclear Operator, and all Euroclear securities clearance accounts and Euroclear cash accounts are accounts with the Euroclear Operator, not Euroclear plc. Euroclear plc establishes policy for Euroclear on behalf of Euroclear Participants. Euroclear Participants include banks, including central banks, securities brokers and dealers and other professional financial intermediaries. Indirect access to Euroclear is also available to other firms that clear through or maintain a custodial relationship with a Euroclear Participant, either directly or indirectly.

The Euroclear Operator is a Belgian bank. As such it is regulated by the Belgian Banking and Finance Commission.

Securities clearance accounts and cash accounts with the Euroclear Operator are governed by the Terms and Conditions Governing Use of Euroclear and the related Operating Procedures of the Euroclear System, and applicable Belgian law, herein the Terms and Conditions. The Terms and Conditions govern transfers of securities and cash within Euroclear, withdrawals of securities and cash from Euroclear, and receipts of payments with respect to securities in Euroclear. All securities in Euroclear are held on a fungible basis without attribution of specific certificates to specific securities clearance accounts. The Euroclear Operator acts under the Terms and Conditions only on behalf of Euroclear Participants, and has no record of or relationship with persons holding through Euroclear Participants. Distributions with respect to debt securities held beneficially through Euroclear will be credited to the cash accounts of Euroclear Participants in accordance with the Terms and Conditions, to the extent received by the U.S. Depositary for Euroclear.

Euroclear has further advised us that investors that acquire, hold and transfer interests in the debt securities by book-entry through accounts with the Euroclear Operator or any other securities intermediary are subject to the laws and contractual provisions governing their relationship with their intermediary, as well as the laws and contractual provisions governing the relationship between such an intermediary and each other intermediary, if any, standing between themselves and the global securities.

Global Clearance and Settlement Procedures

Initial settlement for the debt securities will be made in immediately available funds. Secondary market trading between DTC participants will occur in the ordinary way in accordance with DTC rules and will be settled in immediately available funds using DTC's Same-Day Funds Settlement System. Secondary market trading between Clearstream Participants and/or Euroclear Participants will occur in the ordinary way in accordance with the applicable rules and operating procedures of Clearstream and Euroclear and will be settled using the procedures applicable to conventional eurobonds in immediately available funds.

Cross-market transfers between persons holding directly or indirectly through DTC, on the one hand, and directly or indirectly through Clearstream Participants or Euroclear Participants, on the other, will be effected through DTC in accordance with DTC rules on behalf of the relevant European international clearing system by its U.S. Depositary; however, such cross-market transactions will require delivery of instructions to the relevant European international clearing system by the counterparty in such system in accordance with its rules and procedures and within its established deadlines (European time). The relevant European international clearing system will, if the transaction meets its settlement requirements, deliver instructions to its U.S. Depositary to take action to effect final settlement on its behalf by delivering or receiving debt securities through DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Clearstream Participants and Euroclear Participants may not deliver instructions directly to their respective U.S. Depositaries.

Because of time-zone differences, credits of debt securities received through Clearstream or Euroclear as a result of a transaction with a DTC participant will be made during subsequent securities settlement processing and dated the business day following the DTC settlement date. Such credits or any transactions in such debt securities settled during such processing will be reported to the relevant Euroclear Participants or Clearstream Participants on such business day. Cash received in Clearstream or Euroclear as a result of sales of debt securities by or through a Clearstream Participant or a Euroclear Participant to a DTC participant will be received with value on the DTC settlement date but will be available in the relevant Clearstream or Euroclear cash account only as of the business day following settlement in DTC.

If the debt securities are cleared only through Euroclear and Clearstream (and not DTC), you will be able to make and receive through Euroclear and Clearstream payments, deliveries, transfers, exchanges, notices, and other transactions involving any securities held through those systems only on days when those systems are open for business. Those systems may not be open for business on days when banks, brokers, and other institutions are open for business in the United States. In addition, because of time-zone differences, U.S. investors who hold their interests in the securities through these systems and wish to transfer their interests, or to receive or make a payment or delivery or exercise any other right with respect to their interests, on a particular day may find that the transaction will not be effected until the next business day in Luxembourg or Brussels, as applicable. Thus, U.S. investors who wish to exercise rights that expire on a particular day may need to act before the expiration date.

Although DTC, Clearstream and Euroclear have agreed to the foregoing procedures in order to facilitate transfers of debt securities among participants of DTC, Clearstream and Euroclear, they are under no obligation to perform or continue to perform such procedures and such procedures may be modified or discontinued at any time. Neither we nor any paying agent will have any responsibility for the performance by DTC, Euroclear or Clearstream or their respective direct or indirect participants of their obligations under the rules and procedures governing their operations.

DESCRIPTION OF REGISTERED SHARES

The following description of the material terms of Tyco International's registered shares is based on the provisions of our Swiss articles of association and organizational regulations, which became effective March 17, 2009 upon our change of domicile from Bermuda to Switzerland. This description is not complete and is subject to the applicable provisions of Swiss law and Tyco International's articles of association and organizational regulations, which are filed as exhibits to the registration statement related to this prospectus. The transfer agent and registrar for Tyco International's registered shares is BNY Mellon Shareowner Services. Tyco International's registered shares are listed on the New York Stock Exchange under the ticker symbol "TYC."

Capital Structure

Issued Share Capital

We have one class of share capital, denominated as registered shares. As of November 30, 2011, we had issued 486,362,783 registered shares with a par value per share of CHF 6.70, including approximately 24 million treasury shares.

Authorized Share Capital

Our board of directors is authorized to issue new registered shares at any time on or before March 9, 2013 and thereby increase the share capital, without shareholder approval, by a maximum amount of CHF 1,628,100,000 by issuing a maximum of 243,000,000 fully paid up shares with a par value of CHF 6.70 each. During each two-year period subsequent to March 9, 2013, authorized share capital will be available to our board of directors for issuance of additional registered shares only if authorized by shareholders.

Our board of directors will determine the time of the issuance, the issue price, the manner in which the new registered shares have to be paid, the date from which the new registered shares carry the right to dividends and, subject to the provisions of our articles of association, the conditions for the exercise of preemptive rights with respect to the issuance and the allotment of preemptive rights that are not exercised. Our board of directors may allow preemptive rights that are not exercised to expire, or it may place such rights or registered shares, the preemptive rights of which have not been exercised, at market conditions or use them otherwise in the interest of Tyco International.

In an authorized capital increase, our shareholders would have preemptive rights to obtain newly issued registered shares in an amount proportional to the par value of the registered shares they already hold. Our board of directors, however, may withdraw or limit these preemptive rights in certain circumstances as set forth in our articles of association. For further details on these circumstances, see "Preemptive Rights and Advance Subscription Rights."

Conditional Share Capital for Financing Purposes

Our articles of association provide for a conditional capital that allows our board of directors to increase share capital by up to CHF 321,127,717 through the issue of a maximum of 47,929,510 registered shares, payable in full, each with a nominal value of CHF 6.70 without obtaining additional shareholder approval. These registered shares may be issued through the exercise of conversion, exchange, option, warrant or similar rights for the subscription of shares granted in connection with bonds, options, warrants or other securities newly or already issued in national or international capital markets or new or already existing contractual obligations by Tyco International, one of its subsidiaries, or any of their respective predecessors.

In connection with the issuance of bonds, notes, warrants or other financial instruments or contractual obligations convertible into or exercisable or exchangeable for our registered shares, our

Table of Contents

board of directors may withdraw or limit the advance subscription rights of shareholders in certain circumstances. See "Preemptive Rights and Advance Subscription Rights".

Conditional Share Capital for Employee Participation Purposes

Our articles of association provide for conditional capital that allows our board of directors to increase share capital by up to CHF 321,127,717 through the issue of a maximum of 47,929,510 registered shares, payable in full, each with a nominal value of CHF 6.70 without obtaining additional shareholder approval. These registered shares may be issued in connection with the issuance of registered shares, options or other share-based awards to directors, officers, employees and other persons providing services to us or one of our subsidiaries. Shareholders do not have preemptive rights with respect to registered shares issued to directors, employees, contractors, consultants or other persons providing services to Tyco International or any of our subsidiaries.

Other Classes or Series of Shares

Our board of directors may not create shares with increased voting powers without an authorizing resolution adopted by shareholders holding at least two-thirds of the voting rights and a majority of the par value of the registered shares represented at a general meeting. Our board of directors may create preferred stock with the vote of a majority of the voting rights represented at a general meeting.

Preemptive Rights and Advance Subscription Rights

Under the Swiss Code of Obligations, which we call the Swiss Code, the prior approval of a general meeting of shareholders generally is required to authorize the issuance of registered shares or rights to subscribe for, or convert into, registered shares. In addition, shareholders have preemptive rights in relation to such registered shares or rights in proportion to the respective par values of their holdings. With the affirmative vote of shareholders holding two-thirds of the voting rights and a majority of the par value of the registered shares represented at the general meeting, shareholders may withdraw or limit the preemptive rights for valid reasons, such as a merger, an acquisition or any of the reasons authorizing our board of directors to withdraw or limit the preemptive rights of shareholders in the context of an authorized capital increase as described below.

If the general meeting of shareholders has approved the creation of authorized or conditional capital, it thereby delegates the decision whether to withdraw or limit the preemptive and advance subscription rights for valid reasons to our board of directors. Our articles of association provide for this delegation with respect to our authorized and conditional share capital in the circumstances described below under "Rights with Respect to Authorized Share Capital" and "Rights with Respect to Conditional Share Capital."

Rights with Respect to Authorized Share Capital

Our board of directors is authorized to withdraw or limit the preemptive rights with respect to the issuance of registered shares from authorized capital:

•: if the issue price of the new registered shares is determined by reference to the market price;
•: if the registered shares are issued in connection with the acquisition of an enterprise or business or any part of an enterprise or business, the financing or refinancing of any such transactions or the financing of new investment plans;
•: if the registered shares are issued in connection with the intended broadening of the shareholder constituency in certain financial or investor markets, for the purposes of the participation of strategic partners or in connection with the listing of the registered shares on domestic or foreign stock exchanges;

Table of Contents

•: in connection with a placement or sale of registered shares, the grant of an over-allotment option of up to 20% of the total number of registered shares in a placement or sale of registered shares to the initial purchasers or underwriters;
•: for the participation of directors, employees, contractors, consultants and other persons performing services for our benefit; or
•: either following a shareholder or group of shareholders acting in concert having acquired in excess of 15% of the share capital recorded in the commercial register without having submitted a takeover proposal to shareholders that is recommended by the board of directors or for purposes of the defense of an actual, threatened or potential unsolicited takeover bid, in relation to which our board of directors, upon consultation with an independent financial adviser, has not recommended acceptance to the shareholders.

Rights with Respect to Conditional Share Capital

In connection with the issuance of bonds, notes, warrants or other financial instruments or contractual obligations convertible into or exercisable or exchangeable for our registered shares, shareholders do not have preemptive rights, and our board of directors is authorized to withdraw or limit the advance subscription rights of shareholders with respect to registered shares issued from our conditional share capital if the issuance is for purposes of the acquisition of an enterprise or business or the financing or refinancing of any such transactions, or if the issuance occurs in national or international capital markets or through a private placement.

If the advance subscription rights are withdrawn or limited:

•: the respective financial instruments or contractual obligations will be issued or entered into at market conditions;
•: the conversion, exchange or exercise price, if any, for instruments or obligations will be set with reference to the market conditions prevailing at the date on which the instruments or obligations are issued or entered into; and
•: the instruments or obligations may be converted, exercised or exchanged during a maximum period of 20 years.

Preemptive rights and the advance subscription rights are excluded with respect to registered shares issued from our conditional share capital to directors, officers, employees and other persons providing services to Tyco International or any of our subsidiaries.

Dividends

Under Swiss law, dividends may be paid out only if the corporation has sufficient distributable profits from the previous fiscal year, or if the corporation has distributable reserves. Payments out of the registered share capital—the aggregate par value of a company's registered share capital—must be made by way of a capital reduction. See "Reduction of Share Capital". Contributed surplus may be paid out as dividends to shareholders to the extent permissible under the Swiss Code. The affirmative vote of shareholders holding a majority of the registered shares represented at a general meeting must approve reserve reclassifications and distributions of dividends. Our board of directors may propose to shareholders that a dividend be paid but cannot itself authorize the dividend.

Under the Swiss Code, if our general reserves amount to less than 20% of the share capital recorded in the commercial register, then at least 5% of our annual profit must be retained as general reserves. We allocated the full 20% to a general reserve on our unconsolidated parent company statutory balance sheet in connection with the Change of Domicile. The Swiss Code and our articles of association permit us to accrue additional general reserves. In addition, we are required to create a

Table of Contents

special reserve on our parent company annual statutory balance sheet in the amount of the purchase price of registered shares we or any of our subsidiaries repurchase, and this amount may not be used for dividends or subsequent repurchases.

Swiss corporations generally must maintain a separate parent company "statutory" balance sheet for the purpose of determining the amounts available for the return of capital to shareholders, including by way of a distribution of dividends. A special audit report must confirm that a dividend proposal made to shareholders conforms with the requirements of the Swiss Code and our articles of association.

We expect future dividend payments to be made out of contributed surplus and denominated in U.S. dollars.

Repurchases of Registered Shares

The Swiss Code limits a corporation's ability to hold or repurchase its own registered shares. We and our subsidiaries may only repurchase shares to the extent that sufficient freely distributable reserves (including contributed surplus) are available, as described under "Dividends." The aggregate par value of our registered shares held by us and our subsidiaries may not exceed 10% of our registered share capital. We may repurchase our registered shares beyond the statutory limit of 10%, however, if shareholders have passed a resolution at a general meeting of shareholders authorizing the board of directors to repurchase registered shares in an amount in excess of 10% and the repurchased shares are dedicated for cancellation. Any registered shares repurchased pursuant to such an authorization will then be cancelled at the next general meeting upon the approval of shareholders holding a majority of the registered shares represented at the general meeting. Repurchased registered shares held by us or our subsidiaries do not carry any rights to vote at a general meeting of shareholders but are entitled to the economic benefits generally associated with the shares.

Reduction of Share Capital

Capital distributions also may take the form of a distribution of cash or property that results in a reduction of our share capital recorded in the commercial register. Such a capital reduction requires the approval of shareholders holding a majority of the registered shares represented at the general meeting. A special audit report must confirm that creditors' claims remain fully covered despite the reduction in the share capital recorded in the commercial register. Upon approval by the general meeting of shareholders of the capital reduction, the board of directors must give public notice of the capital reduction resolution in the Swiss Official Gazette of Commerce three times and notify creditors that they may request, within two months of the third publication, satisfaction of or security for their claims.

General Meetings of Shareholders and Voting Rights

General Meetings of Shareholders

The general meeting of shareholders is our supreme corporate body. Ordinary and extraordinary shareholders meetings may be held. The following powers are vested exclusively in the shareholders meeting:

•: adoption and amendment of our articles of association;
•: election of members of the board of directors and the auditor;
•: approval of the annual business report, the stand-alone statutory financial statements and the consolidated financial statements;

Table of Contents

•: payments of dividends and any other distributions of capital to shareholders, excluding share repurchases below 10% of the registered share capital to the extent that sufficient freely distributable reserves are available;
•: discharge of the members of the board of directors from liability for business conduct during the previous fiscal year to the extent such conduct is known to the shareholders; and
•: any other resolutions that are submitted to a general meeting of shareholders pursuant to law, our articles of association or by voluntary submission by the board of directors, unless a matter is within the exclusive competence of the board of directors pursuant to the Swiss Code.

Under the Swiss Code and our articles of association, we must hold an annual, ordinary general meeting of shareholders within six months after the end of our fiscal year for the purpose of approving the annual financial statements and the annual business report and the annual election of directors. The invitation to general meetings must be published in the Swiss Official Gazette of Commerce at least 20 calendar days prior to the relevant general meeting of shareholders. The notice of a meeting must state the items on the agenda and the proposals of the board of directors and of the shareholders who demanded that a shareholders meeting be held or that an item be included on the agenda and, in case of elections, the names of the nominated candidates. No resolutions may be passed at a shareholders meeting concerning agenda items for which proper notice was not given, except for proposals made during a shareholders meeting to convene an extraordinary shareholders meeting or to initiate a special investigation. No previous notification will be required for proposals concerning items included on the agenda or for debates as to which no vote is taken.

Annual general meetings of shareholders may be convened by the board of directors or, under certain circumstances, by the auditor. A general meeting of shareholders can be held anywhere.

An extraordinary general meeting of shareholders may be called upon the resolution of our board of directors or, under certain circumstances, by the auditor. In addition, our board of directors is required to convene an extraordinary general meeting of shareholders if so resolved by the general meeting of shareholders, or if so requested by shareholders holding an aggregate of at least 10% of the registered shares, specifying the items for the agenda and their proposals, or if it appears from the parent company annual statutory balance sheet that half of our share capital and reserves are not covered by our assets. In the latter case, our board of directors immediately must convene an extraordinary general meeting of shareholders and propose financial restructuring measures.

Under our articles of association and our organizational regulations, any shareholder in compliance with the legal requirements may request that an item be included on the agenda of a general meeting of shareholders and may nominate one or more directors for election. A request for inclusion of an item on the agenda or a nominee must be in writing, must specify the items and proposals and must be submitted in accordance with certain advance notice procedures. Under the Swiss Code, a general meeting of shareholders for which a notice of meeting has been duly published may not be adjourned without publishing a new notice of meeting.

Our annual report and auditor's report must be made available for inspection by the shareholders at our place of incorporation no later than 20 days prior to the meeting. Each shareholder is entitled to request immediate delivery of a copy of these documents free of charge. Shareholders of record will be notified of this in writing.

Voting

Each registered share carries one vote at a general meeting of shareholders. Voting rights may be exercised by shareholders registered in the share register or by a duly appointed proxy of a registered shareholder, which proxy need not be a shareholder. Our articles of association contain a provision regarding voting rights that is customary for Swiss companies. This provision provides that, to be able

Table of Contents

to exercise voting rights, holders of shares must apply to us for enrollment in our share register (Aktienregister) as shareholders with voting rights. Registered holders of shares may obtain the form of declaration from our transfer agent, which currently is BNY Mellon Shareowner Services. In order to exercise their voting rights, shareholders will be required to disclose their name and address and that they have acquired their shares in their name and for their account in order to be recorded in our share register as shareholders with voting rights. Persons not expressly declaring themselves to be holding shares for their own account in the application for entry in the share register will not be registered as shareholders with voting rights. Certain exceptions exist with regard to nominees. Legal entities or partnerships or other associations or joint ownership arrangements which are linked through capital ownership or voting rights, through common management or in like manner, as well as individuals, legal entities or partnerships (especially syndicates) which act in concert with intent to evade the entry restrictions are considered as one shareholder or nominee. Failing registration as shareholders with voting rights, shareholders may not participate in or vote at our shareholders' meetings, but will be entitled to dividends, preemptive rights and liquidation proceeds. Only shareholders that are registered as shareholders with voting rights on the relevant record date are permitted to participate in and vote at a general shareholders' meeting.

Treasury shares, whether owned by us or one of our majority-owned subsidiaries, will not be entitled to vote at general meetings of shareholders.

With respect to the election of directors, each holder of registered shares entitled to vote at the election has the right to vote, in person or by proxy, the number of registered shares held by him for as many persons as there are directors to be elected. Directors are elected by the affirmative vote of an absolute majority of the registered shares represented and voting at the general meeting of shareholders. All valid votes cast, including blank votes and abstentions, will be recognized for purposes of establishing the number of votes cast. Our articles of association do not provide for cumulative voting for the election of directors.

Pursuant to our articles of association, shareholders generally pass resolutions by the affirmative vote of a relative majority of the registered shares represented and voting at the general meeting of shareholders unless otherwise provided by law or our articles of association. Broker non-votes, abstentions and blank and invalid ballots will not be counted for purposes of determining approval of proposals unless otherwise provided by law or our articles of association.

The acting chair may direct that elections be held by use of an electronic voting system. Electronic resolutions and elections are considered equal to resolutions and elections taken by way of a written ballot.

Supermajority Voting

The Swiss Code and our articles of association require the affirmative vote of at least two-thirds of the voting rights and a majority of the par value of the registered shares, each as represented at a general meeting to approve the following matters:

•: the amendment to or the modification of our corporate purpose;
•: the creation of shares with privileged voting rights;
•: the restriction on the transferability of shares and any amendment in relation thereto;
•: the restriction on the exercise of the right to vote and any amendment in relation thereto;
•: an authorized or conditional increase in the nominal share capital;
•: an increase in the nominal share capital through the conversion of capital surplus, through a contribution in kind, or in exchange for an acquisition of assets, or a grant of special privileges;

Table of Contents

•: the restriction or withdrawal of preemptive rights;
•: a change in our place of incorporation;
•: the conversion of registered shares into bearer shares and vice versa; and
•: our dissolution.

The same supermajority voting requirements apply to resolutions in relation to transactions among corporations based on Switzerland's Federal Act on Mergers, Demergers, Transformations and the Transfer of Assets, which we refer to as the Merger Act, including a merger, demerger or conversion of a corporation, other than a cash-out or certain squeeze-out mergers, in which minority shareholders of the company being acquired may be compensated in a form other than through shares of the acquiring company, where an affirmative vote of 90% of the outstanding registered shares is required. Swiss law also may impose this supermajority voting requirement in connection with the sale of "all or substantially all of its assets". See "Other Rights and Share Information—Compulsory Acquisitions; Appraisal Rights."

Quorum for General Meetings

According to our articles of association, all resolutions and elections made by the shareholders' meeting require the presence of half plus one of all shares entitled to vote. Abstentions, broker non-votes and blank or invalid ballots will be regarded as present for purposes of establishing a quorum of shareholders. Under the Swiss Code, the board of directors has no authority to waive quorum requirements stipulated in a company's articles of association.

Other Rights and Share Information

Inspection of Books and Records

Under the Swiss Code, a shareholder has a right to inspect the share register with regard to his own shares and otherwise to the extent necessary to exercise his shareholder rights. No other person has a right to inspect the share register. The books and correspondence of a Swiss corporation may be inspected with the express authorization of the general meeting of shareholders or by resolution of the board of directors and subject to the safeguarding of the company's business secrets. At a general meeting of shareholders, any shareholder is entitled to request information from the board of directors concerning the affairs of the company. Shareholders also may ask the auditor questions regarding its audit of the company. The board of directors and the auditor must answer shareholders' questions to the extent necessary for the exercise of shareholders' rights and subject to prevailing business secrets or other material interests of the corporation.

Special Investigation

If the shareholders' inspection and information rights as outlined above prove to be insufficient, any shareholder may propose to the general meeting of shareholders that specific facts be examined by a special commissioner in a special investigation. If the general meeting of shareholders approves the proposal, we or any shareholder, within 30 calendar days after the general meeting of shareholders, may request the court at our registered office to appoint a special commissioner. If the general meeting of shareholders rejects the request, one or more shareholders representing at least 10% of the share capital or holders of registered shares in an aggregate par value of at least two million Swiss francs may request the court to appoint a special commissioner. The court will issue such an order if the petitioners can demonstrate that the board of directors, any member of the board or an officer infringed the law or our articles of association and thereby damaged us or our shareholders. The costs of the investigation generally would be allocated to us and only in exceptional cases to the petitioners.

Table of Contents

Compulsory Acquisitions; Appraisal Rights

Business combinations and other transactions that are binding on all shareholders are governed by the Merger Act. A statutory merger or demerger requires that at least two-thirds of the registered shares and a majority of the par value of the registered shares represented at the general meeting of shareholders vote in favor of the transaction. Under the Merger Act, a "demerger" may take two forms:

•: a legal entity may divide all of its assets and transfer such assets to other legal entities, with the shareholders of the transferring entity receiving equity securities in the acquiring entities and the transferring entity dissolving upon deregistration in the commercial register; or
•: a legal entity may transfer all or a portion of its assets to other legal entities, with the shareholders of the transferring entity receiving equity securities in the acquiring entities.

If a transaction under the Merger Act receives all of the necessary consents, all shareholders would be compelled to participate in the transaction. See "Shareholders Meetings and Voting Rights."

Swiss corporations may be acquired through the direct acquisition of their share capital. With respect to corporations limited by shares, the Merger Act provides for the possibility of a so-called "cash-out" or "squeeze-out" merger if the acquirer controls 90% of the outstanding registered shares. In these limited circumstances, minority shareholders of the corporation being acquired may be compensated in a form other than through shares of the acquiring corporation, for instance, through cash or securities of a parent corporation of the acquiring corporation or of another corporation. For business combinations effected in the form of a statutory merger or demerger and subject to Swiss law, the Merger Act provides that, if the equity rights have not been adequately preserved or compensation payments in the transaction are unreasonable, a shareholder may request the competent court to determine a reasonable amount of compensation.

In addition, under Swiss law, the sale of the overwhelming part of the corporation's assets may require a resolution of the general meeting of shareholders passed by holders of at least two-thirds of the voting rights and a majority of the par value of the registered shares, each as represented at the general meeting of shareholders. Whether or not a shareholder resolution is required depends on the particular transaction, including whether the following test is satisfied:

•: the corporation sells a core part of its business, without which it is economically impracticable or unreasonable to continue to operate the remaining business;
•: the corporation's assets, after the divestment, are not invested in accordance with the corporation's statutory business purpose; and
•: the proceeds of the divestment are not earmarked for reinvestment in accordance with the corporation's business purpose but, instead, are intended for distribution to shareholders or for financial investments unrelated to the corporation's business.

If all of the foregoing apply, a shareholder resolution likely would be required.

Anti-Takeover Provisions

Under Swiss law, there generally is no prohibition of business combinations with interested shareholders. In certain circumstances, however, shareholders and members of the board of directors of Swiss corporations, as well as certain persons associated with them, must refund any payments they receive that are not made on an arm's length basis.

Table of Contents

Our articles of association authorize our board of directors to issue shares out of authorized share capital without shareholder approval and without regard for shareholders' preemptive rights if:

•: a shareholder or group of shareholders acting in concert acquires in excess of 15% of the share capital recorded in the commercial register; and
•: such shareholders or group of shareholders has not submitted a takeover proposal to shareholders that is recommended by the board of directors or for the purpose of the defense of an actual, threatened or potential unsolicited takeover bid, in relation to which the board of directors, upon consultation with an independent financial adviser, has not recommended acceptance to the shareholders.

In addition, our articles of association limit the number of registered shares that may be voted by a single shareholder or group of shareholders acting together to 15% of our registered share capital. For other provisions that could be considered to have an anti-takeover effect see "Preemptive Rights and Advance Subscription Rights" and "Corporate Governance."

Corporate Governance

In addition to articles of association, Swiss corporations enact organization rules in the form of organizational regulations which further define the task and duties of the board of directors and executive management. The organizational regulations are enacted and amended by the board of directors.

Duration; Dissolution; Rights upon Liquidation

Our duration is unlimited. We may be dissolved at any time with the approval of shareholders holding two-thirds of the voting rights and a majority of the par value of the registered shares represented at a general meeting. Dissolution by court order is possible if we become bankrupt, or for cause at the request of shareholders holding at least 10% of our registered share capital. Under Swiss law, any surplus arising out of liquidation, after the settlement of all claims of all creditors, will be distributed to shareholders in proportion to the paid-up par value of registered shares held, subject to Swiss withholding tax requirements.

Uncertificated Shares

We are authorized to issue registered shares in certificated or uncertificated form, but intend to issue only uncertificated shares.

No Sinking Fund

The registered shares have no sinking fund provisions.

No Liability for Further Calls or Assessments

When the registered shares offered hereby are issued, they will be duly and validly issued, fully paid and nonassessable.

No Redemption and Conversion

The registered shares are not convertible into shares of any other class or series or subject to redemption either by us or by the holder of the shares.

Table of Contents

Transfer and Registration of Shares

We have not imposed any restrictions applicable to the transfer of our registered shares. Our share register will initially be kept by BNY Mellon Shareowner Services. The share register reflects only record owners of our shares. Swiss law does not recognize fractional share interests.

Limitation of Liability and Indemnification

Our articles of association provide that we shall indemnify and hold harmless, to the fullest extent permitted by Swiss law, the existing and former members of our board of directors and our officers from and against all threatened, pending or completed actions, suits or proceedings—whether civil, criminal, administrative or investigative—and all costs, charges, losses, damages and expenses which they or any of them, their heirs, executors or administrators, shall or may incur or sustain by or by reason of any act done or alleged to be done, concurred or alleged to be concurred in or omitted or alleged to be omitted in or about the execution of their duty, or alleged duty, or by reason of the fact that he is or was a member of our board of directors or one of our officers, or while serving as a member of our board of directors or as one of our officers is or was serving at our request as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, except that this indemnity does not extend to any matter in which any of person is found, in a final judgment or decree of a court or governmental or administrative authority of competent jurisdiction not subject to appeal, to have committed an intentional or grossly negligent breach of his statutory duties as a member of the board of directors or officer.

We may advance the expenses of defending any such act, suit or proceeding in accordance with and to the full extent now or hereafter permitted by law. Such indemnification and advancement of expenses are not exclusive of any other right to indemnification or advancement of expenses provided by law or otherwise.

We maintain $250 million of insurance to reimburse the directors and officers of us and our subsidiaries for charges and expenses incurred by them for wrongful acts claimed against them by reason of their being or having been directors or officers of us International or any of our subsidiaries. Such insurance specifically excludes reimbursement of any director or officer for any charge or expense incurred in connection with various designated matters, including libel or slander, illegally obtained personal profits, profits recovered by us pursuant to Section 16(b) of the Exchange Act and deliberate dishonesty.

DESCRIPTION OF OTHER SECURITIES

We will set forth in the applicable prospectus supplement a description of any purchase contracts, warrants or units that may be offered pursuant to this prospectus.

Table of Contents

PLAN OF DISTRIBUTION

We may sell the offered securities through agents, through underwriters or dealers, directly to one or more purchasers, through a combination of any of these methods of sale or through any other methods described in a prospectus supplement. The distribution of securities may be effected, from time to time, in one or more transactions, including block transactions and transactions on The New York Stock Exchange or any other organized market where the securities may be traded. The securities may be sold at a fixed price or prices, which may be changed, or at market prices prevailing at the time of sale, at prices relating to the prevailing market prices or at negotiated prices. The consideration may be cash or another form negotiated by the parties. Agents, underwriters or dealers may be paid compensation for offering and selling the securities. That compensation may be in the form of discounts, concessions or commissions to be received from us or from the purchasers of the securities. We will identify the specific plan of distribution, including any underwriters, dealers, agents or direct purchasers and their compensation in a prospectus supplement.

In connection with any particular offering pursuant to this shelf registration statement, an underwriter may engage in stabilizing transactions, over-allotment transactions, syndicate covering transactions and penalty bids.

•: Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum price.
•: Over-allotment involves sales by an underwriter of securities in excess of the number of securities an underwriter is obligated to purchase, which creates a syndicate short position. The short position may be either a covered short position or a naked short position. In a covered short position, the number of securities over-allotted by an underwriter is not greater than the number of securities that it may purchase pursuant to an over-allotment option. In a naked short position the number of securities involved is greater than the number of securities in an over-allotment option. An underwriter may close out any short position by either exercising its over-allotment option and/or purchasing securities in the open market.
•: Syndicate covering transactions involve purchases of the securities in the open market after the distribution has been completed in order to cover syndicate short positions where there is an over-allotment option. In determining the source of securities to close out the short position, an underwriter will consider, among other things, the price of securities available for purchase in the open market as compared to the price at which they may purchase securities through the over-allotment option. If an underwriter sells more securities than could be covered by the over-allotment option, a naked short position, the position can only be closed out by buying securities in the open market. A naked short position is more likely to be created if an underwriter is concerned that there could be downward pressure on the price of the securities in the open market after pricing that could adversely affect investors who purchase in the offering.
•: Penalty bids permit representatives to reclaim a selling concession from a syndicate member when the securities originally sold by the syndicate member are purchased in a stabilizing or syndicate covering transaction to cover syndicate short positions.

These stabilizing transactions, syndicate covering transactions and penalty bids may have the effect of raising or maintaining the market price of our securities or preventing or retarding a decline in the market price of the securities. As a result, the price of our securities may be higher than the price that might otherwise exist in the open market. These transactions may be effected on the New York Stock Exchange or otherwise and, if commenced, may be discontinued at any time.

ENFORCEMENT OF CIVIL LIABILITIES

TIFSA and Tyco will consent in the indenture to jurisdiction in the U.S. federal and state courts in The City of New York and to service of process in The City of New York in any legal suit, action or proceeding brought to enforce any rights under or with respect to the indenture, the notes and the guarantees. Any judgment against TIFSA or Tyco in respect of the indenture, the notes or the guarantees, including for civil liabilities under the U.S. federal securities laws, obtained in any U.S. federal or state court may have to be enforced in the courts of Luxembourg or Switzerland. Investors should not assume that the courts of Luxembourg or Switzerland would enforce judgments of U.S. courts obtained against TIFSA or Tyco predicated upon the civil liability provisions of the U.S. federal securities laws or that such courts would enforce, in original actions, liabilities against TIFSA or Tyco predicated solely upon such laws.

Luxembourg

TIFSA is incorporated under the laws of Luxembourg. Certain members of TIFSA's board of directors are non-residents of the United States and a substantial portion of TIFSA's assets and the assets of its directors are located outside the United States. As a result, you may not be able to effect a service of process within the United States on TIFSA or on such persons or to enforce in Luxembourg courts judgments obtained against TIFSA or such persons in U.S. courts, including actions predicated upon the civil liability provisions of the U.S. federal and state securities laws or other laws. Likewise, it may also be difficult for an investor to enforce in U.S. courts judgments obtained against TIFSA or such persons in courts in jurisdictions outside the United States, including actions predicated upon the civil liability provisions of the U.S. securities laws.

TIFSA has been advised by Allen & Overy Luxembourg, its Luxembourg counsel, that the United States and the Grand-Duchy of Luxembourg are not currently bound by a treaty providing for reciprocal recognition and enforcement of judgments (other than arbitral awards) rendered in civil and commercial matters. According to such counsel, an enforceable judgment for the payment of monies rendered by any U.S. federal or state court based on civil liability, whether or not predicated solely upon the U.S. securities laws, would not directly be enforceable in Luxembourg. However, a party who received such favorable judgment in a U.S. court may initiate enforcement proceedings in Luxembourg (exequatur) by requesting enforcement of the U.S. judgment to the president of the District Court (Tribunal d'Arrondissement) pursuant to article 678 of the New Luxembourg code of Civil Procedure. The president of the District Court will authorize the enforcement in Luxembourg of the U.S. judgment if it is satisfied that all of the following conditions are met:

•: the U.S. judgment is enforceable (executoire) in the United States;
•: the jurisdictional ground of the U.S. court is founded according to Luxembourg conflict of jurisdiction rules and to the applicable domestic U.S. federal or state jurisdiction rules;
•: the U.S. court has applied to the dispute the substantive law which would have been designated by Luxembourg conflict of law rules;
•: the U.S. court has acted in accordance with its own procedural laws;
•: the U.S. judgment must not have violated the right of the defendant to present a defense;
•: the foreign judgment must not have been rendered as a result of or in connection with an evasion of Luxembourg law ("fraude à la loi"); and
•: the U.S. judgment does not contravene Luxembourg international public policy. In practice, Luxembourg courts tend not to review the merits of a U.S. judgment.

Table of Contents

Switzerland

Tyco International is a corporation organized under the laws of Switzerland. Certain members of Tyco International's board of directors are non-residents of the United States, and a substantial portion of Tyco International's assets and the assets of its directors are located outside the United States. Additionally, a substantial majority of Tyco International's directly held assets consist of shares in TIFSA. As a result, in a lawsuit based on the civil liability provisions of the U.S. federal or state securities laws, U.S. investors may find it difficult to:

•: effect service within the United States upon Tyco International or its directors and officers located outside the United States;
•: enforce judgments obtained against those persons in U.S. courts or in courts in jurisdictions outside the United States; and
•: enforce against those persons in Switzerland, whether in original actions or in actions for the enforcement of judgments of U.S. courts, civil liabilities based solely upon the U.S. federal or state securities laws.

Tyco has been advised by its legal advisors that the United States and Switzerland do not currently have a treaty providing for reciprocal recognition of and enforcement of judgments in civil and commercial matters. The recognition and enforcement of a judgment of the courts of the United States in Switzerland is governed by the principles set forth in the Swiss Federal Act on Private International Law. This statute provides in principle that a judgment rendered by a non-Swiss court may be enforced in Switzerland only if:

•: the foreign court had jurisdiction pursuant to the Swiss Federal Act on Private International Law;
•: the judgment of such foreign court has become final and non-appealable;
•: the judgment does not contravene Swiss public policy;
•: the court procedures and the service of documents leading to the judgment were in accordance with the due process of law; and
•: no proceeding involving the same position and the same subject matter was first brought in Switzerland, or adjudicated in Switzerland, or that it was earlier adjudicated in a third state and this decision is recognizable in Switzerland.

Some remedies available under the laws of U.S. jurisdictions, including some remedies available under the U.S. federal securities laws, may not be allowed in Swiss courts as contrary to that jurisdiction's public policy. Therefore, a final judgment for the payment of money rendered by any U.S. federal or state court in the United States based on civil liability, whether or not based solely on U.S. federal or state securities laws, would not automatically be enforceable in Switzerland. Similarly, those judgments may not be enforceable in countries other than the United States.

Item 15. Indemnification of Directors and Officers

Tyco's articles of association provide that it shall indemnify and hold harmless, to the fullest extent permitted by Swiss law, the existing and former members of the board of directors and officers out of the assets of Tyco from and against all threatened, pending or completed actions, suits or proceedings—whether civil, criminal, administrative or investigative—and all costs, charges, losses, damages and expenses which they or any of them, their heirs, executors or administrators, shall or may incur or sustain by or by reason of any act done or alleged to be done, concurred or alleged to be concurred in or omitted or alleged to be omitted in or about the execution of their duty, or alleged duty, or by reason of the fact that he is or was a member of the board of directors or an officer of Tyco, or while serving as a member of the board of directors or officer of Tyco is or was serving at the request of Tyco as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise; provided, however, that this indemnity shall not extend to any matter in which any of said persons is found, in a final judgment or decree of a court or governmental or administrative authority of competent jurisdiction not subject to appeal, to have committed an intentional or grossly negligent breach of his statutory duties as a member of the board of directors or officer.

Tyco may advance the expenses of defending any such act, suit or proceeding in accordance with and to the full extent now or hereafter permitted by law. Such indemnification and advancement of expenses are not exclusive of any other right to indemnification or advancement of expenses provided by law or otherwise.

Item 16. Exhibits

A list of exhibits included as part of this Registration Statement is set forth in the Exhibit Index which immediately precedes such exhibits and is incorporated herein by reference.

Item 17. Undertakings

(a)

The undersigned registrant hereby undertakes:

(1)

to file, during any period in which offers or sales are being made of the securities registered hereby, a post-effective amendment to this registration statement:

(i): to include any prospectus required by Section 10(a)(3) of the Securities Act;
(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 SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; and
(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 undertakings set forth in paragraphs (i), (ii) and (iii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the SEC by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(2)

that, for the purpose of determining any liability under the Securities Act, 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 initialbona 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.

(4)

that, for the purpose of determining any liability under the Securities Act to any purchaser.

(i): Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

II-2

Table of Contents

(ii): Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the thereof.Provided,however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date;
(iii): Each prospectus filed pursuant to Rule 424(b) as part of the registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness.Provided, however, that no statement made in the registration statement or prospectus that is part of the registration statement or made in a document incorporated by or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

(5)

that, for the purpose of determining any liability of the registrant under the Securities Act to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i): Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;
(ii): Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;
(iii): The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and
(iv): Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(b): The registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant's annual report pursuant to Section 13(a) or 15(d) of the Exchange Act and where applicable, each filing of an employee benefit plan's annual report

II-3

Table of Contents

pursuant to Section 15(d) of the Exchange Act 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 initialbona fide offering thereof.

(c)

The registrant hereby undertakes to deliver or cause to be delivered with the prospectus, to each person to whom the prospectus is sent or given, the latest annual report to security holders that is incorporated by reference in the prospectus and furnished pursuant to and meeting the requirements of Rule 14a-3 or Rule 14c-3 under the Securities Exchange Act of 1934; and, where interim financial information required to be presented by Article 3 of Regulation S-X are not set forth in the prospectus, to deliver, or cause to be delivered to each person to whom the prospectus is sent or given, the latest quarterly report that is specifically incorporated by reference in the prospectus to provide such interim financial information.

(d)

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the provisions described in Item 15 hereof, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities 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 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.

(e)

The undersigned registrant hereby undertakes that for the purposes of determining any liability under the Securities Act:

(1): The information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective; and
(2): Each post-effective amendment that contains a form of prospectus 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.

(f)

The undersigned registrant hereby undertakes to file an application for the purpose of determining the eligibility of the trustee to act under subsection (a) of Section 310 of the Trust Indenture Act in accordance with the rules and regulations prescribed by the Commission under Section 305(b)(2) of the Trust Indenture Act.
