Description of Allergan Funding SCS debt securities

This section describes the general terms that will apply to any debt securities that Allergan SCS may offer pursuant to this prospectus and a related prospectus supplement. The specific terms of any offered debt securities, and the extent to which the general terms described in this section apply to these debt securities, will be described in a related prospectus supplement at the time of the offering. The prospectus supplement that will be filed with the SEC may or may not modify the general terms found in this prospectus. For a complete description of any series of debt securities, you should read both this prospectus and the prospectus supplement relating to that series of debt securities.

For purposes of this description, references to (i) “Allergan” are to Allergan plc and not to any of its current or future subsidiaries, (ii) the “Company,” “we,” “us,” “our” and “Allergan SCS” are to Allergan Funding SCS, a common limited partnership (société en commandite simple) organized under the laws of the Grand Duchy of Luxembourg, (iii) “Warner Chilcott” are to Warner Chilcott Limited, a Bermuda exempted company, and not to any of its current or future subsidiaries, (iv) “Allergan Capital” are to Allergan Capital S.à r.l., a private limited liability company (société à responsabilité limitée) incorporated under the laws of the Grand Duchy of Luxembourg and not to any of its current or future subsidiaries and (v) “Allergan Finance” are to Allergan Finance, LLC, a Nevada limited liability company, and not to any of its current or future subsidiaries.

As used in this section, “debt securities” means the debentures, notes, bonds and other evidence of indebtedness offered pursuant to this prospectus and a related prospectus supplement and authenticated by the trustee and delivered under the indenture described below.

Allergan SCS may issue debt securities under the indenture dated as of March 12, 2015, entered into with Wells Fargo Bank, National Association, as trustee (the “ trustee ”), and Warner Chilcott, Allergan Capital and Allergan Finance as guarantors (as amended, supplemented or otherwise modified from time to time, the “ Indenture ”). If a different trustee or a different indenture for a series of debt securities is used, those details will be provided in a prospectus supplement and any other indentures will be filed with the SEC at the time they are used.

We have summarized below the material provisions of the Indenture and the debt securities, or indicated which material provisions will be described in a related prospectus supplement. For further information, you should read the Indenture. The Indenture is an exhibit to the registration statement of which this prospectus forms a part. The following summary is qualified in its entirety by the provisions of the Indenture.

General

The aggregate principal amount of debt securities that we may offer under the Indenture is unlimited. We may issue registered debt securities from time to time and in one or more series. Each series of debt securities may have different terms. The terms of any series of debt securities will be established in or pursuant to a resolution, or actions taken pursuant to a resolution, certified by our general partner to have been duly adopted by the board of managers of our general partner, or in a supplement to the Indenture relating to that series.

The supplemental indenture relating to any series of debt securities that we may offer will state the price or prices at which the debt securities will be offered and will contain the specific terms of that series. These terms may include the following:

10

Table of Contents

11

Table of Contents

We are not obligated to issue all debt securities of one series at the same time. Unless otherwise provided in the related supplemental indenture with respect to a series of debt securities, we may, without the consent of holders of any series of debt securities, increase the principal amount of the series by issuing additional debt securities in the future on the same terms and conditions, except for any difference in the issue price and interest accrued prior to the issue date of the additional debt securities, and with the same CUSIP number, so long as such additional debt securities constitute part of the same issue as the debt securities originally issued for U.S. federal income tax purposes. The debt securities originally issued and any additional debt securities would rank equally and ratably and would be treated as a single series of debt securities for all purposes under the Indenture.

Ranking

Unless otherwise specified, the debt securities are:

Guarantees

The debt securities issued under the Indenture will be fully and unconditionally guaranteed by Warner Chilcott, Allergan Capital and Allergan Finance. The term “ Guarantor ” refers to Warner Chilcott, Allergan Capital and Allergan Finance, each as a guarantor of the debt securities, and the term “ Guarantee ” refers to each such person’s guarantee of the debt securities.

12

Table of Contents

Each Guarantee of the debt securities will be:

Claims of creditors of the subsidiaries of Warner Chilcott that do not guarantee the debt securities, including trade creditors and creditors holding debt and guarantees issued by such subsidiaries, and claims of preferred stockholders (if any) of those subsidiaries generally will have priority with respect to the assets and earnings of such subsidiaries over the claims of our creditors and the creditors of the Guarantors, including holders of the debt securities. For more information, see “Risk factors” in the related prospectus supplement.

The Guarantees will terminate and the Guarantors will be deemed released from all of their obligations under the Indenture upon covenant defeasance as provided under “—Defeasance—Covenant defeasance” below or satisfaction and discharge of the Indenture as provided under “—Defeasance—Satisfaction and discharge” below. Any release described in this paragraph may be evidenced by a supplemental indenture or other instrument, which may be entered into without the consent of any holders of debt securities.

The obligations of each Guarantor under its Guarantee will be limited as necessary to prevent that Guarantee from constituting a fraudulent conveyance under applicable law.

Interest

Each series of debt security will be dated the date of its authentication and will bear interest from the applicable date specified thereon, which will be payable on the dates specified on the face of the form of such debt security. Unless otherwise specified in the related supplemental indenture with respect to a series of debt securities, if any payment date with respect to the debt securities falls on a day that is not a business day, we may make the payment on the next business day with the same force and effect as if it had been made on the original payment date, and no interest will accrue on the payment after the original payment date.

Redemption and repurchase

The related supplemental indenture with respect to a series of debt securities will indicate whether we have the option or obligation to redeem or repurchase any debt securities of such series in whole or in part prior to their maturity date. If we have the option or obligation to redeem or repurchase any series of the debt securities prior to maturity, the related supplemental indenture with respect thereto will indicate the redemption price, the method for redemption and the period or periods within which we may redeem or repurchase such debt securities.

See “—Optional redemption for changes in withholding taxes” for a description of the optional redemption of the debt securities in the event of certain tax developments.

Table of Contents

Additional amounts

All payments required to be made by us under or with respect to the debt securities or by any Guarantor under or with respect to a Guarantee (each of us or such Guarantor and, in each case, any successor thereof, making such payment, the “ Payor ”), will be made free and clear of, and without withholding or deduction for or on account of, any taxes imposed or levied by or on behalf of any authority or agency having power to tax within any jurisdiction in which any Payor is incorporated, organized or otherwise resident for tax purposes, or engaged in business for tax purposes, or any jurisdiction from or through which payment is made by or on behalf of such Payor (each a “ Relevant Taxing Jurisdiction ”), unless such Payor is required to withhold or deduct such taxes by law or regulation.

If a Payor is so required to withhold or deduct any amount for or on account of taxes imposed or levied by or on behalf of a Relevant Taxing Jurisdiction from any payment made under or with respect to the debt securities or a Guarantee, as applicable, such Payor will be required to pay such additional amounts (“ Additional Amounts ”) as may be necessary so that the net amount received by any holder (including Additional Amounts) after such withholding or deduction will not be less than the amount the holder or beneficial owner would have received if such taxes had not been withheld or deducted; provided , however , that the foregoing obligation to pay Additional Amounts does not apply to:

14

Table of Contents

The Payor will pay any present or future stamp, issue, registration, excise, property, court or documentary taxes, or similar taxes, charges or levies and interest, penalties and other reasonable expenses related thereto that arise in or are levied by any Relevant Taxing Jurisdiction on the execution, issuance, delivery, enforcement or registration of the debt securities, the Indenture, the Guarantees or any other document or instrument in relation thereto (other than on a transfer or assignment of the debt securities of any series after the offering thereof).

The Payor will make or cause to be made any withholding or deduction required in respect of taxes, and remit the full amount deducted or withheld to the Relevant Taxing Jurisdiction, in accordance with applicable law. Upon request, the Payor will use reasonable efforts to provide, within a reasonable time after the date the payment of any such taxes so deducted or withheld is made, the trustee with official receipts or other documentation evidencing the payment of the taxes so deducted or withheld.

If any Payor will be obligated to pay Additional Amounts under or with respect to any payment made on the debt securities, the Payor will deliver to the paying agent with a copy to the trustee on a date that is at least 30 days prior to the date of that payment (unless the obligation to pay Additional Amounts arises after the 45th day prior to that payment date, in which case the Payor shall notify the paying agent and the trustee promptly thereafter) a certificate stating the fact that Additional Amounts will be payable and the amount estimated to be so payable and such other information reasonably necessary to enable the paying agent to pay Additional Amounts to holders or beneficial owners on the relevant payment date.

Whenever in the Indenture or this “Description of Allergan Funding SCS debt securities” there is mentioned, in any context:

15

Table of Contents

such reference will be deemed to include payment of Additional Amounts as described under this section “—Additional amounts,” to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof.

The obligations described under this section “—Additional amounts” will survive any termination, defeasance or discharge of the Indenture or any Guarantee and will apply mutatis mutandis to any jurisdiction in which any successor Person (as defined under “— Certain covenants—Definition of certain terms” below) to the Payor is incorporated, organized or otherwise resident for tax purposes or any political subdivision or taxing authority or agency thereof or therein.

Optional redemption for changes in withholding taxes

We are entitled to redeem any series of debt securities, at our option, at any time in whole but not in part, upon not less than 30 nor more than 60 days’ notice to the holders, at a redemption price equal to 100% of the outstanding principal amount thereof, plus accrued and unpaid interest, if any, to the date of redemption (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date), in the event any Payor has become or would become obligated to pay, on the next date on which any amount would be payable with respect to such series of debt securities, any Additional Amounts (but, in the case of a Guarantor, only if such amount could not be paid by us or another Guarantor who can pay such amount without the obligation to pay Additional Amounts), in each case, as a result of:

which change, amendment or introduction is publicly announced or becomes effective on or after the date of the Indenture or the relevant supplemental indenture relating to the original issuance of the affected series of debt securities and the Payor cannot avoid such obligation by taking reasonable measures available to it (including making payment through a Paying Agent located in another jurisdiction). The foregoing provisions will apply mutatis mutandis to the laws and official positions of any jurisdiction in which any successor permitted under “—Certain covenants—Merger, amalgamation, consolidation or sale of assets” is incorporated, organized or otherwise resident for tax purposes or any political subdivision or taxing authority or agency thereof or therein.

Prior to the giving of any notice of redemption described in the preceding paragraph, we will deliver to the trustee an officer’s certificate to the effect that the Payor cannot avoid its obligation to pay Additional Amounts by taking reasonable measures available to it. We will also deliver to the trustee an opinion of counsel of recognized standing to the effect that the Payor would be obligated to pay Additional Amounts as a result of a change, amendment, or introduction described above. Absent manifest error, the trustee will accept such opinion as sufficient evidence of the Payor’s obligations, to pay such Additional Amounts, and it will be conclusive and binding on the holders.

Repurchase upon a change of control

If a Change of Control Triggering Event (as defined below) occurs with respect to any series of debt securities, unless we have redeemed the relevant series of debt securities in full, we will make an offer to each holder (the “ Change of Control Offer ”) of such debt securities to repurchase any and all (equal to $1,000 or an integral multiple of $1,000 in excess thereof) of such holder’s debt securities at a repurchase price in cash equal to 101% of the aggregate principal amount of the debt securities to be repurchased plus accrued and unpaid interest, if any, to, but excluding, the date of purchase (the “ Change of Control Paymen t”). Within 30 days following any

16

Table of Contents

Change of Control Triggering Event, we will be required to mail a notice to holders of the relevant debt securities describing the transaction or transactions that constitute the Change of Control Triggering Event and offering to repurchase their debt securities on the date specified in the notice, which date will be no earlier than 15 days and no later than 60 days from the date such notice is mailed (the “ Change of Control Payment Date ”), pursuant to the procedures required by the debt securities and described in such notice. We must comply with the requirements of Rule 14e-1 under the Exchange Act, and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the debt securities as a result of a Change of Control Triggering Event. Notwithstanding anything to the contrary contained herein, a Change of Control Offer may be made in advance of a Change of Control (as defined below), conditioned upon the consummation of such Change of Control, if a definitive agreement is in place for the Change of Control at the time the Change of Control Offer is made. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control repurchase provisions of the debt securities, we will be required to comply with the applicable securities laws and regulations and will not be deemed to have breached our obligations under the Change of Control repurchase provisions of the debt securities by virtue of such conflicts.

On the Change of Control Payment Date, with respect to any series of debt securities, we will be required, to the extent lawful, to:

“ Below Investment Grade Rating Event ” means, with respect to any series of debt securities, that such series of debt securities is rated below Investment Grade Rating by both of the Rating Agencies on any date commencing upon the first public notice by us of the occurrence of a Change of Control or our intention to effect a Change of Control and ending 60 days following consummation of such Change of Control (which period shall be extended so long as the rating of such series of debt securities is under publicly announced consideration for possible downgrade by either of the Rating Agencies).

“ Change of Control ” means the occurrence of any of the following:

17

Table of Contents

For purposes of this definition, “voting stock” means with respect to any specified person (as that term is used in Section 13(d)(3) of the Exchange Act) capital stock of any class or kind the holders of which are ordinarily, in the absence of contingencies, entitled to vote for the election of directors (or persons performing similar functions) of such person, even if the right to vote has been suspended by the happening of such a contingency.

The definition of Change of Control includes a phrase relating to the direct or indirect sale, lease, transfer, conveyance or other disposition of “all or substantially all” of the properties or assets of Allergan and its subsidiaries taken as a whole. Although there is a limited body of case law interpreting the phrase “substantially all,” there is no precise established definition of the phrase under applicable law. Accordingly, the applicability of the requirement that we offer to repurchase the debt securities as a result of a sale, lease, transfer, conveyance or other disposition of less than all of the assets of Allergan and its subsidiaries taken as a whole to another person or group may be uncertain.

“ Change of Control Triggering Event ” means the occurrence of both a Change of Control and a Below Investment Grade Rating Event.

“ Investment Grade Rating ” means a rating by Moody’s equal to or higher than Baa3 (or the equivalent under a successor rating category of Moody’s) or a rating by S&P equal to or higher than BBB- (or the equivalent under any successor rating category of S&P).

“ Moody’s ” means Moody’s Investors Service, Inc., and any successor to its ratings agency business.

“ Rating Agencies ” means (1) Moody’s and S&P; and (2) if either or both of Moody’s or S&P ceases to rate a particular series of debt securities or fails to make a rating of a particular series of debt securities publicly available for reasons outside of our control, then, in each case, for such series of debt securities, a “nationally recognized statistical rating organization” within the meaning of Rule 15c3-1 (c)(2)(vi)(F) under the Exchange Act, selected by us (as certified by a resolution of our board of directors) as a replacement agency for either Moody’s, S&P, or both of them, as the case may be.

18

Table of Contents

“ S&P ” means Standard & Poor’s Ratings Services, a Standard & Poor’s Financial Services LLC business and any successor to its rating agency business.

Certain covenants

Limitations on liens

The Indenture contains the following exceptions to the foregoing prohibition:

Although these types of transactions are permitted under the Indenture, certain of the foregoing transactions could constitute a Change of Control, permitting each holder to require us to repurchase the debt securities of such holder, as described under “—Repurchase upon a Change of Control” above.

Reports to holders

Warner Chilcott will:

If at any time Allergan plc (or a successor thereto) is the direct or indirect parent company of Warner Chilcott, then the reports, information and other documents required to be furnished to holders of the debt securities pursuant to this covenant may, at our option, be furnished by and be those of Allergan plc (or its successor) rather than Warner Chilcott; provided that a reasonably detailed description of any material differences between

21

Table of Contents

Allergan plc’s financial information and Warner Chilcott’s financial information will be provided in each annual and quarterly report. Any report required to be furnished under this covenant will be deemed furnished upon public filing with the SEC.

The trustee shall have no obligation to determine whether Warner Chilcott has made any filings with the SEC and shall have no duty to solicit annual and quarterly reports or related information.

Holding company status

For so long as any series of debt securities are outstanding, no subsidiary of Allergan that, directly or indirectly through any other subsidiary, owns any Equity Interests (as defined below) in Warner Chilcott (other than any such subsidiary of Allergan that fully and unconditionally guarantees the debt securities) will and, unless Allergan provides a guarantee of the debt securities, Allergan (each such subsidiary and, as long as applicable, Allergan, the “ Passive Holding Companies ”) will not, conduct, transact or otherwise engage in any active trade or business or operations other than through a subsidiary of Warner Chilcott; provided that the foregoing will not prohibit any Passive Holding Company from the following: (i) ownership of Equity Interests of Warner Chilcott or in one or more subsidiaries of Allergan that are Passive Holding Companies, (ii) the maintenance of its legal existence and, with respect to Allergan, its status as a public company (including the ability to incur fees, costs and expenses relating to such maintenance), (iii) the performance of its obligations with respect to any indebtedness in respect of which it is an obligor and any other agreement to which it is a party, (iv) with respect to Allergan, any offering of its common stock or any other Equity Interests (including any mandatorily redeemable preferred stock and any equity-linked securities) or, with respect to any Passive Holding Company other than Allergan, any other issuance of its Equity Interests, (v) the making of payments on account of its Equity Interests or any subordinated debt, (vi) the incurrence of indebtedness, (vii) the making of contributions to (or other equity investments in) the capital of its direct subsidiaries (which will be Passive Holding Companies or Warner Chilcott), (viii) the creation of, and ownership of the Equity Interests in, any a newly formed subsidiary with capitalization of less than $1,000,000 that is formed solely for the purpose of consummating an acquisition by Allergan so long as, within twelve months such newly formed subsidiary merges with and into a target entity and the survivor thereof becomes a direct or indirect subsidiary of Warner Chilcott or its subsidiaries, (ix) providing a guarantee of indebtedness or other obligations of Allergan or any of its subsidiaries, (x) participating in tax, accounting and other administrative matters as a member or parent of the consolidated group, (xi) holding any cash or cash equivalents (including cash and cash equivalents received in connection with dividends or distributions from Warner Chilcott or its subsidiaries) and any other assets on a temporary basis that are in the process of being transferred through such Passive Holding Company as part of a downstream contribution or an upstream distribution or other upstream payment (e.g., a spin-off of assets), (xii) providing indemnification to officers and directors, (xiii) the ownership or disposition of assets that are permitted to be held by it in accordance with this covenant and (xiv) activities incidental to the businesses or activities described above.

Certain other covenants

The Indenture contains certain other covenants regarding, among other matters, payment of principal, premium, if any, and interest, if any, on the debt securities, maintenance of a payment office, delivering of compliance certificates and payment of taxes. The Indenture does not contain restrictive covenants relating to total indebtedness, interest coverage, stock repurchases, recapitalizations, dividends and distributions to shareholders or current ratios. Other than as described above, the provisions of the Indenture will not afford holders of the debt securities protection in the event of a sudden or significant decline in our credit quality or in the event of a takeover, recapitalization or highly leveraged or similar transaction involving us or any of our affiliates that may adversely affect such holders.

23

Table of Contents

In addition, the term “indebtedness” includes (x) all indebtedness of others secured by a Lien on any asset of the specified Person (whether or not such indebtedness is assumed by the specified Person), provided that the amount of such indebtedness will be the lesser of (A) the fair market value of such asset at such date of determination and (B) the amount of such indebtedness, and (y) to the extent not otherwise included, the guarantee by the specified Person of any indebtedness of any other Person.

“ Lien ” means, with respect to any asset, any mortgage, lien, pledge, charge, security interest or encumbrance of any kind in respect of such asset, whether or not filed, recorded or otherwise perfected under applicable law, including any conditional sale or other title retention agreement, any lease in the nature thereof, any option or other agreement to sell or give a security interest in and any filing of or agreement to give any financing statement under the Uniform Commercial Code (or equivalent statutes) of any jurisdiction.

24

Table of Contents

“ Value ” means, with respect to a Sale and Leaseback Transaction, an amount equal to the net present value of the lease payments with respect to the term of the lease remaining on the date as of which the amount is being determined, without regard to any renewal or extension options contained in the lease, discounted at the weighted average interest rate on the debt securities of all series which are outstanding on the effective date of such Sale and Leaseback Transaction.

Events of default

The Indenture defines an Event of Default with respect to each series of debt securities as any one of the following events:

and, in each case, the amount of any such indebtedness, together with the amount of any other indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $300 million or more; provided , however , that, if the default under the mortgage, indenture or instrument is cured by us or the applicable Guarantor, or waived by the holders of the indebtedness, in each case as permitted by the governing mortgage, indenture or instrument, then the Event of Default caused by such default will be deemed likewise to be cured or waived.

25

Table of Contents

An Event of Default under one series of debt securities will not necessarily constitute an Event of Default under any other series of debt securities. The Indenture provides that the trustee may withhold notice to the holders of any series of debt securities issued thereunder of any default if and so long as the trustee in good faith determines that withholding the notice is in the interests of the holders of the debt securities of such series; provided that the trustee may not withhold notice of default in payment of the principal, premium, if any, interest, if any, on any of the debt securities of that series.

Remedies if an Event of Default occurs

In the case of an Event of Default arising from certain events of bankruptcy or insolvency, with respect to Warner Chilcott, Allergan Capital, us or Allergan Finance, all outstanding debt securities issued under the Indenture will become due and payable immediately without further action or notice. If any other Event of Default occurs and is continuing, the trustee or the holders of at least 25% in aggregate principal amount of the then outstanding debt securities may declare all the debt securities to be due and payable immediately.

Subject to certain limitations, holders of a majority in aggregate principal amount of the then outstanding debt securities may direct the trustee in its exercise of any trust or power.

Subject to the provisions of the Indenture relating to the duties of the trustee, in case an Event of Default occurs and is continuing, the trustee will be under no obligation to exercise any of the rights or powers under the Indenture at the request or direction of any holders of debt securities of any series unless such holders of that series have offered to the trustee indemnity or security reasonably satisfactory to the trustee against any loss, liability or expense. No holder of a debt security of any series may pursue any remedy with respect to the Indenture or the debt securities of such series unless:

The holders of a majority in aggregate principal amount of the then outstanding debt securities of the affected series by written notice to the trustee may, on behalf of the holders of all of the debt securities of that series, rescind an acceleration or waive any existing default or Event of Default and its consequences under the Indenture, if the rescission would not conflict with any judgment or decree, except a continuing default or Event of Default in the payment of principal of, premium on, if any, or interest, if any, on, the debt securities of that series.

We are required to deliver to the trustee annually a statement regarding compliance with the Indenture. Upon becoming aware of any default or Event of Default, we are required to deliver to the trustee a statement specifying such default or Event of Default.

Modification and waiver

There are four types of changes we can make to the Indenture and the debt securities.

Changes requiring your approval . First, without the consent of each holder of debt securities of any series affected by the change, there are changes that we cannot make to the debt securities of such series (but only with respect to any debt securities of any series held by a non-consenting holder). Following is a list of those types of changes:

Changes not requiring approval . The second type of change does not require any vote by holders of the debt securities. Following is a list of those types of changes:

27

Table of Contents

28

Table of Contents

Changes requiring a majority vote . Any other change to the Indenture and the debt securities would require the following approval:

Holders of not less than a majority in aggregate principal amount of the debt securities of any series then outstanding may, by written notice to the trustee on behalf of the holders of all of the securities of such series, waive an existing default or event of default and its consequences, except a continuing default or event of default in the payment of the principal amount, premium, if any, and any accrued and unpaid interest, if any, on any debt security of such series.

Further details concerning voting

The debt securities will not be considered outstanding, and therefore not eligible to vote, if we have deposited or set aside, segregated and held in trust money for their payment or redemption. The debt securities will also not be eligible to vote if they have been fully defeased as described under “—Defeasance—Full defeasance” below.

We will generally be entitled to set any day as a record date for the purpose of determining the holders of outstanding debt securities that are entitled to vote or take other action under the Indenture. In certain limited circumstances, the trustee will be entitled to set a record date for action by holders. If we or the trustee set a record date for a vote or other action to be taken by holders of debt securities, that vote or action may be taken only by persons who are holders of outstanding debt securities on the record date and must be taken within 180 days following the record date or another period that we may specify (or as the trustee may specify, if it set the record date). We may shorten or lengthen (but not beyond 180 days) this period from time to time.

Defeasance

Unless otherwise specified in a related supplemental indenture with respect to a series of debt securities, the following discussion of full defeasance and discharge will apply to all series of the debt securities.

Full defeasance

If there is a change in U.S. federal tax law, as described below, we can legally release ourselves from any payment or other obligations on any series of debt securities (called “ full defeasance ”) if the following conditions are satisfied:

29

Table of Contents

If we accomplished full defeasance, as described above, holders would have to rely solely on the trust deposit for repayment of the debt securities. Holders could not look to us for repayment in the event of any shortfall. Conversely, the trust deposit would most likely be protected from claims of our lenders and other creditors if we ever become bankrupt or insolvent.

However, even if we make the deposit in trust and opinion delivery arrangements discussed above, a number of our obligations relating to the debt securities will remain. These include our obligations:

Covenant defeasance

Under current U.S. federal tax law, we can make the same type of deposit described above and be released from some of the covenants in any series of debt securities. This is called “ covenant defeasance .” In that event, holders would lose the protection of those covenants but would gain the protection of having money and securities set aside in trust to repay such series of debt securities. In order to achieve covenant defeasance, we must do the following:

30

Table of Contents

If we accomplish covenant defeasance, holders can still look to us for repayment of the debt securities in the event of a shortfall in the trust deposit, as could occur if there is an Event of Default (such as our bankruptcy) and the debt securities become immediately due and payable. Depending on the event causing the default, you may not be able to obtain payment of the shortfall.

Satisfaction and discharge

The Indenture will cease to be of further effect and the trustee, upon our demand and at our expense, will execute appropriate instruments acknowledging the satisfaction and discharge of the Indenture upon compliance with certain conditions, including:

Judgment currency

Any payment on account of an amount that is payable in U.S. dollars (the “ Required Currency ”), which is made to or for the account of any holder or the trustee in any other lawful currency (the “ Judgment Currency ”), whether as a result of any judgment or order or the enforcement thereof or the liquidation of Allergan SCS, shall constitute a discharge of our obligation under the Indenture and the debt securities, only to the extent of the amount of the Required Currency which such holder or the trustee, as the case may be, could purchase in the New York foreign exchange markets with the amount of the Judgment Currency in accordance with normal banking procedures at the rate of exchange prevailing on the first Business Day following receipt of the payment in the Judgment Currency. If the amount of the Required Currency that could be so purchased is less than the amount of the Required Currency originally due to such holder or the trustee, as the case may be, we shall indemnify and hold harmless the holder or the trustee, as the case may be, from and against all loss or damage arising out of, or as a result of, such deficiency. This indemnity shall constitute an obligation separate and independent from the other obligations contained in the Indenture, any supplemental indenture or the debt securities, shall give rise to a separate and independent cause of action, shall apply irrespective of any indulgence granted by any holder or the trustee from time to time and shall continue in full force and effect notwithstanding any judgment or order for a liquidated sum in respect of an amount due hereunder or under any judgment or order.

Consent to jurisdiction and service of process

The Indenture provides that we and each Guarantor not organized in the United States appoint CT Corporation System as its agent for service of process in any suit, action or proceeding with respect to the Indenture, the debt securities and the Guarantees and for actions brought under the U.S. federal or state securities laws brought in any U.S. federal or state court located in the Borough of Manhattan in the City of New York. In relation to any

31

Table of Contents

legal action or proceedings arising out of or in connection with the Indenture, the debt securities and the Guarantees, we and each Guarantor in the Indenture irrevocably submit to the non-exclusive jurisdiction of the U.S. federal and state courts in the Borough of Manhattan in the City of New York, County and State of New York, United States.

Regarding the trustee

Wells Fargo Bank, National Association, as trustee under the Indenture, is appointed by us as paying agent, registrar and DTC custodian with regard to the debt securities. The trustee, the Guarantors or Allergan or their respective affiliates may from time to time in the future provide banking and other services to us in the ordinary course of their business.

Governing law

The Indenture and any debt securities and guarantees are governed by and construed in accordance with the laws of the State of New York but without giving effect to applicable principles of conflicts of law to the extent that the application of the law of another jurisdiction would be required thereby. For avoidance of doubt, the application of the provisions of articles 470-1 and 470-19 (inclusive) of the Luxembourg law of 10 August 1915 on commercial companies, as amended, is expressly excluded.

Form and registration of debt securities

Unless otherwise specified in a related supplemental indenture with respect to a series of debt securities, debt securities will be issued in registered form, without interest coupons, in the form of global securities, as further described below. We will not impose a service charge in connection with any transfer or exchange of any debt security, but we may in general require payment of a sum sufficient to cover any transfer tax or similar governmental charge imposed in connection with the transfer or exchange.

Global securities

We expect that pursuant to procedures established by DTC (i) upon the issuance of the global securities, DTC or its custodian will credit, on its internal system, the principal amount at maturity of the individual beneficial interests represented by such global securities to the respective accounts of persons who have accounts with such depositary and (ii) ownership of beneficial interests in the global securities will be shown on, and the transfer of such ownership will be effected only through, records maintained by DTC or its nominee (with respect to interests of participants) and the records of participants (with respect to interests of persons other than participants). Such accounts initially will be designated by or on behalf of the relevant underwriters, and ownership of beneficial interests in the global securities will be limited to persons who have accounts with DTC, or “participants,” or to persons who hold interests through participants. Holders may hold their interests in the global securities directly through DTC if they are participants in the system, or indirectly through organizations which are participants in the system.

So long as DTC, or its nominee, is the registered owner or holder of the debt securities, DTC or such nominee, as the case may be, will be considered the sole owner or holder of the debt securities represented by such global securities for all purposes under the Indenture. No beneficial owner of an interest in the global securities will be able to transfer that interest except in accordance with DTC’s procedures, in addition to those provided for under the Indenture.

Payments of the principal of, premium (if any), and interest on, the global securities will be made to DTC or its nominee, as the case may be, as the registered owner thereof. None of us, the trustee or any paying agent will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in the global securities or for maintaining, supervising or reviewing any records relating to such beneficial ownership interest.

32

Table of Contents

We expect that DTC or its nominee, upon receipt of any payment of principal, premium, if any, or interest on the global securities, will credit participants’ accounts with payments in amounts proportionate to their respective beneficial interests in the principal amount of the global securities as shown on the records of DTC or its nominee. We also expect that payments by participants to owners of beneficial interests in the global securities held through such participants will be governed by standing instructions and customary practice, as is now the case with securities held for the accounts of customers registered in the names of nominees for such customers. Such payments will be the responsibility of such participants.

Transfers between participants in DTC will be effected in the ordinary way through DTC’s same-day funds system in accordance with DTC rules and will be settled in same-day funds. If a holder requires physical delivery of a certificated security for any reason, including to sell debt securities to persons in states which require physical delivery of the debt securities, or to pledge such securities, such holder must transfer its interest in a global security, in accordance with the normal procedures of DTC and with the procedures set forth in the Indenture.

DTC has advised us that it will take any action permitted to be taken by a holder of debt securities (including the presentation of debt securities for exchange as described below) only at the direction of one or more participants to whose account the DTC interests in the global securities are credited and only in respect of such portion of the aggregate principal amount of debt securities as to which such participant or participants has or have given such direction. However, if there is an event of default under the Indenture, DTC will exchange the global securities for certificated securities, which it will distribute to its participants.

DTC has advised us as follows: DTC is a limited purpose trust company organized under the laws of the State of New York, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the Uniform Commercial Code and a “Clearing Agency” registered pursuant to the provisions of Section 17A of the Exchange Act. DTC was created to hold securities for its participants and facilitate the clearance and settlement of securities transactions between participants through electronic book- entry changes in accounts of its participants, thereby eliminating the need for physical movement of certificates. Participants include securities brokers and dealers, banks, trust companies and clearing corporations and certain other organizations. Indirect access to the DTC system is available to others such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a participant, either directly or indirectly as indirect participants.

Although DTC has agreed to the foregoing procedures in order to facilitate transfers of interests in the global securities among participants of DTC, it is under no obligation to perform such procedures, and such procedures may be discontinued at any time. Neither we nor the trustee will have any responsibility for the performance by DTC or its participants or indirect participants of their respective obligations under the rules and procedures governing their operations.

Certificated securities

Certificated securities shall be issued in exchange for beneficial interests in the global securities (i) if DTC (A) notifies us that it is unwilling or unable to continue as a depositary for the global securities, and we do not appoint a successor depositary within 90 days of such notice, or (B) ceases to be qualified to serve as depositary and we do not appoint a successor depositary within 90 days of such notice, (ii) we execute and deliver to the trustee a company order that such global security shall be so transferable, registrable and exchangeable, and such transfers shall be registrable, or (iii) an Event of Default of which the trustee has actual notice has occurred and is continuing and the registrar has received a request from a beneficial owner to issue such certificate securities.

Description of Allergan share capital

The following description of our share capital is a summary. You should refer to the provisions of our memorandum and articles of association included as an exhibit to the Registration Statement of which this prospectus forms a part. Our authorized share capital is €40,000 and US$101,000 divided into 40,000 deferred ordinary shares of €1.00 each, 1,000,000,000 ordinary shares of US$0.0001 each and 10,000,000 serial preferred shares of US$0.0001 each. As of February 13, 2018, we had 40,000 deferred ordinary shares, 330,320,420 issued and outstanding ordinary shares and 5,060,000 issued and outstanding 5.500% Mandatory Convertible Preferred Shares, Series A.

Allergan may issue shares subject to the maximum authorized share capital contained in its memorandum and articles of association. The authorized share capital may be increased or reduced (but not below the number of issued ordinary shares, serial preferred shares or deferred ordinary shares, as applicable) by a simple majority of the votes cast at a general meeting at which a quorum is present (referred to under Irish law as an “ ordinary resolution ”). The shares comprising the authorized share capital of Allergan may be divided into shares of such nominal value as the resolution shall prescribe. As a matter of Irish company law, the directors of a company may issue new ordinary, serial preferred or deferred ordinary shares without shareholder approval once authorized to do so by the articles of association or by an ordinary resolution adopted by the shareholders at a general meeting. The authorization may be granted for a maximum period of five years, at which point it must be renewed by the shareholders by an ordinary resolution. The articles of association of Allergan authorize the board of directors of Allergan to issue new ordinary, serial preferred or deferred ordinary shares without shareholder approval for a period of five years from October 1, 2013.

The rights and restrictions to which the ordinary shares are subject are prescribed in Allergan’s articles of association. Allergan’s articles of association permit the board of directors, without shareholder approval, to determine certain terms of each series of the serial preferred shares issued by Allergan, including the number of shares, designations, voting rights, dividend rights, liquidation and other rights and redemption, repurchase or exchange rights.

Irish law does not recognize fractional shares held of record. Accordingly, Allergan’s articles of association do not provide for the issuance of fractional Allergan ordinary shares, and the official Irish register of Allergan will not reflect any fractional shares.

Whenever an alteration or reorganization of the share capital of Allergan would result in any Allergan shareholder becoming entitled to fractions of a share, the Allergan board of directors may, on behalf of those shareholders that would become entitled to fractions of a share, arrange for the sale of the shares representing fractions and the distribution of the net proceeds of sale in due proportion among the shareholders who would have been entitled to the fractions. For the purpose of any such sale the board may authorize some person to transfer the shares representing fractions to the purchaser, who shall not be bound to see to the application of the purchase money, nor shall his title to the shares be affected by any irregularity or invalidity in the proceedings relating to the sale.

Description of Allergan ordinary shares

General

The following description of our ordinary shares is a summary. You should refer to the provisions of our memorandum and articles of association included as an exhibit to the Registration Statement of which this prospectus forms a part. Rights under the ordinary shares are subject to the Irish Companies Act 2014, as amended (the “ Irish Companies Act ”), as described in this prospectus.

Voting

Allergan’s articles of association provide that except where a greater majority is required by the Irish Companies Act or where plurality voting is required pursuant to the articles, any question, business or resolution proposed at any general meeting shall be decided by ordinary resolution.

At any meeting of Allergan, all resolutions will be decided on a show of hands unless a poll is demanded by: (i) the chairman, (ii) at least three shareholders present in person or by proxy, (iii) any shareholder or shareholders present in person or by proxy and representing not less than one-tenth of the total voting rights of all shareholders having the right to vote at such meeting or (iv) any shareholder or shareholders holding shares in Allergan conferring the right to vote at the meeting being shares on which an aggregate sum has been paid up equal to not less than one-tenth of the total sum paid up on all the shares conferring that right. If voting takes place on a poll, rather than a show of hands, every shareholder entitled to vote has one vote for each share held unless otherwise provided in Allergan’s articles of association. Voting rights may be exercised by shareholders registered in the share register as of the record date for the meeting or by a duly appointed proxy of such a registered shareholder, which proxy need not be a shareholder. All proxies must be appointed in accordance with Allergan’s articles of association.

Treasury shares or Allergan ordinary shares that are held by subsidiaries of Allergan will not be entitled to be voted at general meetings of shareholders.

Irish law requires special resolutions (a “ special resolution ” requires the approval of not less than 75% of the votes of Allergan’s shareholders cast (in person or by proxy) at a general meeting at which a quorum is present) of the shareholders at a general meeting to approve certain matters. Examples of matters requiring special resolutions include:

35

Table of Contents

Allergan’s articles of association provide that anything which may be done by resolution at a general meeting may be done by resolution in writing, but only if it is signed by or on behalf of all of the shareholders who would be entitled to attend the relevant meeting and vote on the relevant resolution, subject to the requirements of the Irish Companies Act.

Under the Allergan articles of association and the Irish Companies Act, any variation of class rights attaching to the issued Allergan ordinary shares must be approved in writing by holders of three-quarters of the issued shares in that class or with the sanction of a special resolution passed at a separate general meeting of the holders of the shares of that class.

The provisions of the articles of association of Allergan relating to general meetings apply to general meetings of the holders of any class of shares except that the necessary quorum is determined with reference to the shares of the holders of the class.

Dividend rights

Under Irish law, dividends and distributions may only be made from distributable reserves. Distributable reserves generally means accumulated realized profits less accumulated realized losses and includes reserves created by way of capital reduction. In addition, no distribution or dividend may be made unless the net assets of Allergan are equal to, or in excess of, the aggregate of Allergan’s called-up share capital plus undistributable reserves and the distribution does not reduce Allergan’s net assets below such aggregate. Undistributable reserves include the share premium account, the capital redemption reserve fund and the amount by which Allergan’s accumulated unrealized profits, so far as not previously utilized by any capitalization, exceed Allergan’s accumulated unrealized losses, so far as not previously written off in a reduction or reorganization of capital.

The determination as to whether or not Allergan has sufficient distributable reserves to fund a dividend must be made by reference to “relevant accounts” of Allergan. The “relevant accounts” are either the last set of unconsolidated annual audited financial statements or other financial statements properly prepared in accordance with the Irish Companies Act, which give a “true and fair view” of Allergan’s unconsolidated financial position and accord with accepted accounting practice. The relevant accounts must be filed in the Irish Companies Registration Office (the official public registry for companies in Ireland).

Allergan’s articles of association authorize the directors to pay interim dividends to the extent they appear justified by profits without shareholder approval. The board of directors may also recommend a dividend to be approved and declared by the Allergan shareholders at a general meeting. The board of directors may direct that the payment be made by distribution of assets, shares or cash and no dividend issued may exceed the amount recommended by the directors. Dividends may be declared and paid in the form of cash or non-cash assets and may be paid in U.S. dollars or any other currency. All holders of Allergan ordinary shares will participate pro rata in respect of any dividend which may be declared in respect of ordinary shares by Allergan.

Table of Contents

The directors of Allergan may deduct from any dividend payable to any shareholder any amounts payable by such shareholder to Allergan in relation to the Allergan ordinary shares.

Lien on shares, calls on shares and forfeiture of shares

Allergan’s articles of association provide that Allergan will have a first and paramount lien on every share for all moneys payable, whether presently due or not, in respect of such Allergan share. Subject to the terms of their allotment, directors may call for any unpaid amounts in respect of any shares to be paid, and if payment is not made, the shares may be forfeited. These provisions are standard inclusions in the articles of association of an Irish company limited by shares, such as Allergan, and will only be applicable to Allergan shares that have not been fully paid up.

Consolidation and division; subdivision

Under its articles of association, Allergan may, by ordinary resolution, consolidate and divide all or any of its issued share capital into shares of a larger amount than its existing shares or subdivide all or any of its issued share capital into shares of a smaller amount than its existing shares.

Transfer and registration of shares

The transfer agent for Allergan maintains the share register, registration in which will be determinative of membership in Allergan. A shareholder of Allergan who holds shares beneficially will not be the holder of record of such shares. Instead, the depository or other nominee will be the holder of record of those shares. Accordingly, a transfer of shares from a person who holds such shares beneficially to a person who also holds such shares beneficially through a depository or other nominee will not be registered in Allergan’s official share register, as the depository or other nominee will remain the record holder of any such shares.

A written instrument of transfer is required under Irish law in order to register on Allergan’s official share register any transfer of shares (i) from a person who holds such shares directly to any other person, (ii) from a person who holds such shares beneficially to a person who holds such shares directly or (iii) from a person who holds such shares beneficially to another person who holds such shares beneficially where the transfer involves a change in the depository or other nominee that is the record owner of the transferred shares. An instrument of transfer is also required for a shareholder who directly holds shares to transfer those shares into his or her own broker account (or vice versa). Such instruments of transfer may give rise to Irish stamp duty, which must be paid prior to registration of the transfer on Allergan’s official Irish share register. However, a shareholder who holds shares outside of DTC may transfer those shares into DTC (or vice versa) without giving rise to Irish stamp duty, provided there is no change in the ultimate beneficial ownership of the shares as a result of the transfer and the transfer is not made in contemplation of a sale of the shares by a beneficial owner to a third party.

Any transfer of Allergan ordinary shares that is subject to Irish stamp duty will not be registered in the name of the buyer unless an instrument of transfer is duly stamped and provided to the transfer agent. Allergan’s articles of association allow Allergan, in its absolute discretion, to create an instrument of transfer and pay (or procure the payment of) any stamp duty, which is the legal obligation of a buyer. In the event of any such payment, Allergan is (on behalf of itself or its affiliates) entitled to (i) seek reimbursement from the buyer or seller (at its discretion), (ii) set off the amount of the stamp duty against future dividends payable to the buyer and (iii) claim a lien against the Allergan ordinary shares on which it has paid stamp duty. Parties to a share transfer may assume that any stamp duty arising in respect of a transaction in Allergan ordinary shares has been paid unless one or both of such parties is otherwise notified by Allergan.

Allergan’s articles of association delegate to Allergan’s secretary or assistant secretary the authority to execute an instrument of transfer on behalf of a transferring party.

Table of Contents

In order to help ensure that the official share register is regularly updated to reflect trading of Allergan ordinary shares occurring through normal electronic systems, Allergan intends to regularly produce any required instruments of transfer in connection with any transactions for which it pays stamp duty (subject to the reimbursement and set-off rights described above). In the event that Allergan notifies one or both of the parties to a share transfer that it believes stamp duty is required to be paid in connection with the transfer and that it will not pay the stamp duty, the parties may either themselves arrange for the execution of the required instrument of transfer (and may request a form of instrument of transfer from Allergan for this purpose) or request that Allergan execute an instrument of transfer on behalf of the transferring party in a form determined by Allergan. In either event, if the parties to the share transfer have the instrument of transfer duly stamped (to the extent required) and then provide it to Allergan’s transfer agent, the buyer will be registered as the legal owner of the relevant shares on Allergan’s official Irish share register (subject to the matters described below).

The directors may suspend registration of transfers from time to time, not exceeding 30 days in aggregate each year.

Rights upon liquidation

Allergan’s articles of association provide that the ordinary shareholders of Allergan are entitled to participate pro rata in a winding up, but their right to do so is subject to the rights of any holders of the serial preferred shares to participate under the terms of any series or class of such shares.

Preemption rights

Under Irish law certain statutory preemption rights apply automatically in favor of shareholders where shares are to be issued for cash. However, Allergan has opted out of these preemption rights in its articles of association as permitted under Irish company law. Because Irish law requires this opt-out to be renewed at least every five years by a special resolution of shareholders, Allergan’s articles of association provide that this opt-out must be so renewed. If the opt-out is not renewed, shares issued for cash must be offered to existing shareholders of Allergan on a pro rata basis to their existing shareholding before the shares can be issued to any new shareholders. Statutory preemption rights do not apply where shares are issued for non-cash consideration (such as in a stock-for-stock acquisition) and do not apply to the issue of non-equity shares (that is, shares that have the right to participate only up to a specified amount in any income or capital distribution) or where shares are issued pursuant to an employee option or similar equity plan.

Anti-takeover provisions

Allergan’s articles of association contain provisions that could have the effect of deterring coercive takeover practices, inadequate takeover bids and unsolicited offers. These provisions include, amongst others:

38

Table of Contents

These provisions do not make Allergan immune from takeovers. However, these provisions will apply even if a takeover offer may be considered beneficial by some shareholders and could delay or prevent an acquisition that the board of directors determines is not in Allergan’s or its shareholders best interests. These provisions may also prevent or discourage attempts to remove and replace incumbent directors.

In addition, several mandatory provisions of Irish law could prevent or delay an acquisition of Allergan. For example, Irish law does not permit shareholders of an Irish public limited company to take action by written consent with less than unanimous consent. Allergan is also subject to various provisions of Irish law relating to mandatory bids, voluntary bids, requirements to make a cash offer and minimum price requirements, as well as substantial acquisition rules and rules requiring the disclosure of interests in its ordinary shares in certain circumstances. Also, as an Irish company, Allergan may only alter its memorandum and articles of association by special resolution.

Description of Allergan serial preferred shares

General

We are authorized to issue up to 10,000,000 serial preferred shares of US$0.0001 each. The board of directors may provide by resolution for the issuance of serial preferred shares, in one or more series, and to fix the number of shares constituting those series and the designation of those series, the voting powers (if any) of the shares of such series, and the preferences and relative, participating, optional or other special rights, if any, and any qualifications, limitations or restrictions thereof, of the shares of such series, as are not inconsistent with our articles of association. Rights under the serial preferred shares are subject to the Irish Companies Act. The issuance of serial preferred shares could have the effect of decreasing the market price of the ordinary shares and could adversely affect the voting and other rights of the holders of ordinary shares.

We will include in a related prospectus supplement the terms of any series of serial preferred shares being offered. These terms will include some or all of the following:

Upon issuance, the serial preferred shares will be fully paid and nonassessable. As of February 13, 2018, we had 5,060,000 issued and outstanding 5.500% Mandatory Convertible Preferred Shares, Series A.

Description of Allergan depositary shares

We may issue fractional interests in serial preferred shares, rather than serial preferred shares, with those rights and subject to the terms and conditions that we may specify in a related prospectus supplement. If we do so, we will provide for a depositary (either a bank or trust company depositary that has its principal office in the United States) to issue receipts for depositary shares, each of which will represent a fractional interest in a serial preferred share. The serial preferred shares underlying the depositary shares will be deposited under a deposit agreement between us and the depositary. The related prospectus supplement will include the name and address of the depositary.

Description of Allergan ordinary share warrants

The Irish Companies Act provides that directors may issue share warrants or options without shareholder approval once authorized to do so by the articles of association or an ordinary resolution of shareholders. Allergan’s articles of association confer such right on the board of directors, subject to applicable law and the rules of any stock exchange to which Allergan is subject. Allergan is subject to the rules of the New York Stock Exchange that require shareholder approval of certain equity plans and share issuances. Allergan’s board of directors may issue shares upon exercise of warrants or options without shareholder approval or authorization (up to the relevant authorized share capital limit). The related prospectus supplement will describe the terms of any Allergan ordinary share purchase warrants.

Description of Allergan ordinary share purchase contracts and ordinary share purchase units

Allergan may issue ordinary share purchase contracts, representing contracts obligating holders to purchase from Allergan and obligating Allergan to sell to the holders, or holders to sell to Allergan and Allergan to purchase from the holders, to the extent permitted by the Irish Companies Act, a fixed or varying number of ordinary shares at a future date or dates. The price per ordinary share may be fixed at the time the ordinary share purchase contracts are entered into or may be determined by reference to a specific formula set forth in the ordinary share purchase contracts. Any ordinary share purchase contract may include anti-dilution provisions to adjust the number of ordinary shares to be delivered pursuant to such ordinary share purchase contract upon the occurrence of certain events. The ordinary share purchase contracts may be entered into separately or as a part of ordinary share purchase units consisting of one or more ordinary share purchase contracts and any one or more of the securities offered under this prospectus or debt or equity obligations of third parties, including U.S. Treasury securities, owned by Allergan.

The ordinary share purchase contracts may require holders to secure their obligations in a specified manner, and in certain circumstances we may deliver newly issued prepaid ordinary share purchase contracts upon release to a holder of any collateral securing such holder’s obligations under the original ordinary share purchase contract. Any one or more of the above securities, ordinary shares or the ordinary share purchase contracts, or other collateral, may be pledged as security for the holders’ obligations to purchase or sell, as the case may be, the ordinary shares under the ordinary share purchase contracts. The ordinary share purchase contracts may also allow the holders, under certain circumstances, to obtain the release of the security for their obligations under such contracts by depositing with the collateral agent, as substitute collateral, treasury securities with a principal amount at maturity equal to the collateral so released or the maximum number of ordinary shares deliverable by such holders under ordinary share purchase contracts requiring the holders to sell ordinary shares to Allergan. The terms of any payments provided for under the ordinary share purchase units will be described in the related prospectus supplement.

The related prospectus supplement will describe the terms of any ordinary share purchase contracts or ordinary share purchase units and, if applicable, prepaid ordinary share purchase contracts. The description in the prospectus supplement will be qualified in its entirety by reference to (1) the ordinary share purchase contracts; (2) the collateral arrangements and depositary arrangements, if applicable, relating to such ordinary share purchase contracts or ordinary share purchase units; and (3) if applicable, the prepaid ordinary share purchase contracts and the document pursuant to which such prepaid ordinary share purchase contracts will be issued.
