3. PURPOSE, EFFECTS AND LIMITATIONS OF THE SECURITY INTEREST

The Security Interest created and perfected under this Agreement provides the Assignee, as Collateral Agent, for the benefit and on behalf of the Secured Parties, with a security interest securing the Swissco Obligations.

3.2. First Priority Lien

The Collateral shall be delivered so that this Agreement, together with such delivery, creates in favour of the Assignee, as Collateral Agent, for the benefit and on behalf of the Secured Parties, a first priority lien on, and first priority security interest in such Collateral.

3.3. Continuing Security Interest

This Agreement shall create a continuing Security Interest over the Collateral irrespective of any intermediate payment or satisfaction of any or all Swissco Obligations

3.4. Additional and Independent Security Interest

The Security Interest created and perfected over the Collateral hereunder shall be in addition to and independent of any existing or future guarantees and other security interests which may at any time be held by the Assignee from the Assignor or any other Person in respect of the whole or any part of the Swissco Obligations and may be enforced independently of any such other guarantees or other security interests.

The release of individual items of Collateral from the Security Interest does not affect the Security Interest on other items of Collateral.

3.5. Conflicts

The parties hereto acknowledge that (a) the Assignor and the Assignee, among other parties, have entered into that certain Swissco New York Law Pledge Agreement, dated the date hereof (the “Swissco US Pledge Agreement”), pursuant to which the Assignor has pledged to the Assignee certain equity and debt securities owned by it as security for the Swissco Obligations, and (b) certain of such debt securities may constitute Collateral under this Agreement. In the event of any inconsistency between the terms and conditions of this Agreement and the terms and conditions of the Swissco US Pledge Agreement, the terms and conditions of this Agreement shall prevail, except to the extent the context or applicable law may require.

Notwithstanding anything herein to the contrary, (i) the Liens and security interests granted to the Assignee for the ratable benefit of the Secured Parties pursuant to this Agreement and (ii) the exercise of any right or remedy by the Assignee hereunder or the application of proceeds of any Collateral, are subject to the provisions of any Customary Intercreditor Agreement contemplated by the Credit Agreement, if and to the extent applicable and/or in effect.

3.6 Limitations

If and to the extent the Assignor secures and/or guarantees any Upstream and Cross-Stream Obligations (as such terms are defined in the Credit Agreement), and not obligations that are the Assignor’s primary obligations or the primary obligations of Foreign Subsidiaries that are direct or indirect subsidiaries of the Assignor, the following limitations shall apply:

(a) Maximum amount which may be secured or guaranteed by the Assignor:

The aggregate:

(i) liability of the Assignor; and

(ii) use of proceeds from the enforcement of the Collateral of the Assignor,

under this Agreement and any and all other Loan Documents shall not exceed the amount of the Assignor’s freely disposable equity in accordance with Swiss law, presently being the total shareholder equity less the total of (a) the aggregate share capital and (b) statutory reserves (including reserves for own shares and revaluations as well as agio) to the extent such reserves cannot be transferred into unrestricted, distributable reserves, and (c) the blocked amount (as determined by the Assignor’s statutory auditor) corresponding to the Assignor’s intra-group claims resulting from upstream or cross-stream loans not granted at arm’s length conditions. The amount of freely disposable equity shall be determined on the basis of an audited annual or interim balance sheet of the Assignor.

This limitation shall only apply to the extent it is a requirement under applicable law at the time (a) the Assignor is required to perform or (b) Collateral of the Assignor is enforced under the Loan Documents. Such limitation shall not free the Assignor from its obligations in excess of the freely disposable equity, but merely postpone the performance date thereof until such times when the Assignor has again freely disposable equity if and to the extent such freely disposable equity is available. The limitation shall not apply to the extent the Assignor guarantees any amounts borrowed under any Loan Document that are lent to the Assignor or to wholly owned direct or indirect subsidiaries of the Assignor, and shall accordingly not apply to the Collateral of the Assignor being enforced as security/guarantee for the obligations of the Assignor or the obligations of direct or indirect subsidiaries of the Assignor.

The Assignor shall and Luxembourg Holdco or any successor shareholder of the Assignor which is a party to a Loan Document shall procure that the Assignor will, take and cause to be taken all and any action (including, without limitation, (a) the passing of any shareholders’ resolutions to approve any payment or other performance under this Agreement or any other Loan Document, and (b) the obtaining of any confirmations which may be required as a matter of Swiss mandatory law in force at the time the Assignor is required to make a payment or perform other obligations under this Agreement or any other Loan Document) in order to allow a prompt payment of amounts owing by the Assignor under the Loan Documents, a prompt use of proceeds from the Collateral of the Assignor as well as the performance by the Assignor of other obligations under the Loan Documents with a minimum of limitations.

If the enforcement of the obligations of the Assignor under the Loan Documents would be limited due to the effects referred to in this clause, the Assignor shall further, to the extent permitted by applicable law and Swiss accounting standards and upon request by the Administrative Agent, write up or sell any of its assets that are shown in its balance sheet with a book value that is significantly lower than the market value of the assets, in case of sale, however, only if such assets are not necessary for the Assignor’s business and such sale is permitted under this Agreement or any other Loan Document.

(b) Swiss Withholding Tax

(i) If so required under applicable law (including double tax treaties) at the time it is required to make a payment under this Agreement or any other Loan Document, the Assignor:

(A) shall use its best efforts to ensure that such payments can be made without deduction of Swiss withholding tax (Verrechnungssteuer), or with deduction of Swiss withholding tax at a reduced rate, by discharging the liability to such tax by notification pursuant to applicable law (including tax treaties) rather than payment of the tax;

(B) shall deduct the Swiss withholding tax at such rate (being 35% at the date hereof) as is in force from time to time if the notification procedure pursuant to sub-paragraph (A) above does not apply; or shall deduct the Swiss withholding tax at the reduced rate resulting after discharge of part of such tax by notification if the notification procedure pursuant to sub-paragraph (A) applies for a part of the Swiss withholding tax only; and shall pay within the time allowed any such taxes deducted to the Swiss Federal Tax Administration; and

(C) shall promptly notify the Administrative Agent that such notification or, as the case may be, deduction has been made, and provide the Administrative Agent with evidence that such a notification of the Swiss Federal Tax Administration has been made or, as the case may be, such taxes deducted have been paid to the Swiss Federal Tax Administration.

(ii) If the Assignor is required under applicable law (including double tax treaties) to deduct Swiss withholding tax at the time the Collateral Agent is enforcing the Collateral of Assignor, the Administrative Agent shall deduct from the proceeds from such enforcement the Swiss withholding tax at such rate (being 35% at the date hereof) as is in force from time to time and shall pay without delay, any such taxes deducted to the Swiss Federal Tax Administration.

(iii) In the case of a deduction of Swiss withholding tax, the Assignor shall use its best efforts to ensure that any Person that is entitled to a full or partial refund of the Swiss withholding tax deducted from such payment under this Agreement or any other Loan Document or the proceeds of the enforcement of the Collateral of the Assignor, will, as soon as possible after such deduction:
