At the expiry of the Restricted Period, the Trustee shall have the power to dispose of or transfer the Restricted Shares at the sole direction of the Participant. It shall be the responsibility of the Participant to ensure that such sale or transfer is made in accordance with applicable laws or regulations.

4.9 The Trustee shall, notwithstanding anything to the contrary in this Deed, act in accordance with any obligations imposed on it as a shareholder under the Articles for the time being.

provided that the Trustee’s actions shall not breach Section 128D of the Act.

8 CAPITALISATION ISSUES

In the event of the Company allotting any new securities by way of capitalisation to the Trustee in respect of a Participant’s Restricted Shares, such new securities will, subject to the Act, form part of the Participant’s Restricted Shares and will be deemed to have been acquired at the same time as, and will be held by the Trustee on the same terms as, the Restricted Shares to which such new securities relate.

9 TAKEOVERS AND OTHER TRANSACTIONS AFFECTING SHARES

9.1 In the event that:

9.1.1 an offer is made to acquire a Participant’s Restricted Shares (in this sub-clause referred to as original shares) in circumstances such that acceptance thereof will result in a new holding (as defined in section 584 of the Act) being equated with such original shares for the purposes of capital gains tax;

9.1.2. an offer is made to acquire a Participant’s Restricted Shares as part of a general offer made to holders of shares of the same class as the Restricted Shares or of shares in the Company for a cash consideration, with or without other assets, and is also made in the first instance on a condition such that, if it is satisfied, the person making the offer will have control of the Company (within the meaning of section 432 of the Act); or

9.1.3. a transaction is proposed which affects a Participant’s Restricted Shares or such of them as may be of a particular class and such transaction would be entered into pursuant to a compromise, arrangement or scheme applicable to or affecting all the shares of the Company or, as the case may be, all the Shares of the class in question;

then, notwithstanding any other provision of the Clog Program, the Trustee may, at the direction of the relevant Participant, accept such offer or, as the case may be, agree to such compromise arrangement or plan in respect of his Restricted Shares.

9.2 In the event that any offer is made or compromise, arrangement or plan proposed affecting any of a Participant’s Restricted Shares which does not fall within Clause 9.1, then the relevant Participant may only direct the Trustee to accept or agree thereto to the extent that implementation thereof would not result in a breach of Clause 4.4 or of Section 128D of the Act.

9.3 The Trustee will promptly take all reasonable steps using information supplied by the Company to notify each Participant of the principal terms of any offer, compromise or plan falling within this Clause 9 and in the absence of any direction from a Participant concerning how the Trustee should act thereon in respect of that Participant’s Restricted Shares the Trustee shall not take any action in respect thereof.

9.4 In any of the following events:

9.4.3. if the Company is dissolved by virtue of or pursuant to any statutory provision or any order of the Court made thereunder or otherwise, and another body corporate, person or firm is bound by virtue of or pursuant to any statutory provision or any order of the Court made thereunder or otherwise to perform the said obligations;

9.4.4. if the Company amalgamates or enters into any arrangement having the effect of amalgamation with any other body corporate, person or firm; or

then in any such event, (provided no breach of Section 128D of the Act results) by deed supplemental hereto in such form as the Company and the Trustee require the Company shall be thereby released from all the said obligations, and such other body corporate, person or firm as aforesaid shall be deemed to be substituted for the Company as the person liable to perform the said obligations, and the Deed and the Clog Letter shall henceforth have effect as if such other body corporate, person or firm had been a party to and had executed the Deed in place of the Company and as if the reference to the Company in the Deed were references to such other body corporate, person or firm (save where the context requires otherwise).

Re: Clog Letter in respect of an award of RSUs which may vest in accordance with the terms of the Company’s 2014 Non-Employee Equity Plan (the Plan) on [            ]

Dear [            ],

This letter applies to a maximum of [            ] shares in Horizon Pharma plc (the Company) which may vest to you on [            ] in accordance with the Plan.

You are required to contractually agree to retain such vested shares in Horizon Pharma plc (the Shares) for the specified period of [            ] (the Restricted Period). During the Restricted Period Goodbody Trustees Limited (the Trustee) will hold the legal title to the Shares and will retain the share certificate relevant to the Shares pursuant to the terms of a Deed of Trust executed between the Trustee and the Company on 18 September 2015. During the Restricted Period the Shares will be subject to the Retention Condition (commonly known as a “Clog”) set out in the next paragraph. Please note that the precise number of Shares vesting to you and the Restricted Period will be advised to you on the relevant vesting date of the Shares. The Restricted Period will commence on the date the award of RSUs vests in accordance with the provisions of the Plan and will apply to the Shares issuable or transferable to you at vesting.

Retention Condition attached to the Shares

You shall not assign, charge, pledge as security for a loan or other debt, transfer or otherwise dispose of all or any interest in the Shares in any circumstances during the Restricted Period.

You agree that the Trustee and the Company shall be entitled to treat any attempt to assign, charge, pledge as security for a loan or other debt, transfer or otherwise dispose of all or any interest in the Shares during the Restricted Period, other than where permitted under the Exceptions to the Retention Condition as set out below as null and void.

Please note that by executing and returning the Acceptance Form set out in Schedule 1 to this Letter to the Company you are consenting to and agree to be bound by the Retention Condition which will inhibit your freedom to deal with or realise value from the Shares during the Restricted Period. Please note that your agreement and consent to be bound by the Retention Condition may cause financial loss for which the Company does accept any responsibility.

Exceptions to the Retention Condition

Notwithstanding that you are bound to adhere to the Retention Condition during the Retricted Period you may transfer, assign, charge, pledge as security for a loan or other debt, or otherwise dispose of the Shares in accordance with Section 128D(3)(c) of the Taxes Consolidation Act, 1997 as amended (the Act) which are on the occurrence of the following events:

upon your death, or

as a consequence of you agreeing to

accept an offer for the Shares if the acceptance or agreement would result in a new holding (within the meaning of section 584 of the Act) being equated with the Shares for the purposes of capital gains tax,

a transaction affecting the Shares or such number of the Shares as are of a particular class if the transaction would be entered into pursuant to a compromise, arrangement or scheme applicable to or affecting all the ordinary share capital of Horizon Pharma plc or, as the case may be, all the shares of the same class as the Shares acquired by you, or

accept an offer of cash, with or without other assets, for the Shares if the offer forms part of a general offer made to holders of shares of the same class as the Shares acquired by you or of shares in the same company and made in the first instance on a condition such that if it is satisfied the person making the offer will have control (within the meaning of section 432 of the Act) of that company.

Compulsory Acquisition

It should be noted that if an offer were to be made to acquire the entire issued share capital of the Company, the offeror can, subject to receiving the specified level of acceptances, compulsorily acquire the shares held by those persons who do not accept the offer. If this were to happen, the restriction on disposal of the Shares during the Restricted Period cannot prevent a compulsory acquisition of the Shares. Should the Shares subject to the Restricted Period be disposed of in such circumstances some of the tax relief afforded will be clawed back and due for payment to the Revenue Commissioners.

Taxation

Ireland

The vesting of RSUs will give rise to a gain that is subject to income tax, the Universal Social Charge (USC) and Social Security (if applicable) at your marginal rates. Acceptance of the terms set out in this letter will result in a reduction in the amount of this gain that will be subject to income tax, USC and Social Security (if applicable) but it will not result in the deferral of the resultant tax and Social Security liabilities. The Company is obliged to collect the income tax (PAYE), USC and employee Social Security (if applicable) due by you through payroll deductions via the PAYE system. You may also have tax filing obligations under the self assessment system of “pay and file”.

It is your responsibility to seek taxation advice relevant to your particular circumstances. The Company accepts no responsibility to provide you with such tax advice or for any tax consequences for you for being awarded the Shares.

Normally, the taxable amount of the gain arising on the award of shares will equal the difference between the market value of the shares acquired less any amount paid. However, under Section 128D of the Act, the taxable amount is reduced by [            ]% of the market value of the shares where the Restricted Period is for a period of [            ].

Miscellaneous

This Letter constitutes the entire agreement between you and the Company and supersedes and extinguishes all previous agreements, promises, assurances, warranties, representations and understandings between you and the Company, whether written or oral, relating to the Shares.

This Letter and the Acceptance Form contained in Schedule 1 to this Letter shall be governed by and construed in accordance with Irish law.

Acknowledgement and Consent

By returning the Acceptance Form you signify your acceptance of the arrangement in respect of the Shares issuable or transferable to you on vesting of the Restricted Stock Units under the Plan and the Retention Condition applicable to the Shares during the Restricted Period.
