(b)           to become party to the Security Deed as Lenders and to observe, perform and be bound by the terms and provisions of the Security Deed in the capacity of Lenders in accordance with Clause 9.3 (Transfers by Lenders) of the Security Deed.

6.             The Additional Facility Commitment in relation to an Additional Facility W Lender (for the purpose of the definition of Additional Facility Commitment in Clause 1.1 (Definitions) of the Credit Agreement) is its Facility W Commitment.

7.             Any interest due in relation to Facility W will be payable on the last day of each Interest Period in accordance with Clause 8 (Interest) of the Credit Agreement.

8.             The Availability Period for Facility W shall be the period from and including the Effective Date up to and including the date falling one month before the Final Maturity Date in respect of Facility W.

9.             Facility W shall comprise a committed term loan facility which shall (subject to paragraph 10 below) be capable of being reborrowed in relation to any sums that are prepaid in accordance with Clause 7.10(d) (Miscellaneous provisions) of the Credit Agreement.

10.           UPC Financing shall not deliver a Request in relation to Facility W if as a result of the proposed Request more than 10 Advances under Facility W would be outstanding.

(a)           31 March 2015; and

(b)           17 October 2013 (the Relevant Date) being the date falling 90 days prior to the date on which the UPC Holding B.V. issued bonds due 2014 (the Bonds) are currently scheduled to fall due, if on the Relevant Date, Bonds are outstanding in an aggregate amount equal to or greater than €250,000,000.

17.           (a)            It is the intention of parties that the Existing Facility W be upsized by the amount of this Facility W in accordance with paragraph 17 of each Additional Facility Accession Agreement under which the Existing Facility W is made available and that from the first utilisation date of this Facility W, the Facility W Advance under this

Agreement will be consolidated with the Advances under the Existing Facility W and this Facility W and the Existing Facility W shall constitute one single Additional Facility for all purposes under the Credit Agreement.

(b)           Provided that any upsizing of Facility W permitted under this paragraph will not breach any term of the Credit Agreement, Facility W may be upsized by any amount, by the signing of one or more further Additional Facility W Accession Agreements, that specify (along with the other terms specified therein) UPC Financing as the sole Borrower and which specify Additional Facility W Commitments denominated in euros, to be drawn in euros, with the same Final Maturity Date and Margin as specified in this Additional Facility W Accession Agreement.

(c)           For the purposes of this paragraph 17 (unless otherwise specified), references to Additional Facility W Lenders and Facility W Advances shall include Lenders and Advances made under any such further and previous Additional Facility W Accession Agreement.

(d)           Where any Facility W Advance has not already been consolidated with any other Facility W Advance, on the last day of any Interest Period for such Facility W Advance, that Facility W Advance will be consolidated with any other Facility W Advance which has an Interest Period ending on the same day as that Facility W Advance, and all such Facility W Advances will then be treated as one Advance.

18.           Each of UPC Broadband and UPC Financing confirms, on behalf of themselves and each other Obligor that the representations and warranties set out in Clause 15 (Representations and Warranties) of the Credit Agreement (with the exception of Clauses 15.6(a) (Consents), 15.10 (Financial condition), 15.12 (Security Interests), 15.13(b) (Litigation and insolvency proceedings), 15.14 (Business Plan), 15.15 (Tax liabilities), 15.16 (Ownership of assets), 15.18 (Works Council), 15.19 (Borrower Group Structure), 15.20 (ERISA), 15.24 (UPC Financing) and 15.25 (Dutch Banking Act)) are true and correct as if made at the Effective Date with reference to the facts and circumstances then existing, and as if each reference to the Finance Documents includes a reference to this Agreement.

19.           UPC Broadband further represents and warrants on the Effective Date that the execution and delivery by it of this Agreement and the performance of the transactions contemplated by this Agreement will not violate any agreement or instrument to which UPC Holding is a party or binding upon UPC Holding or any member of the Borrower Group or any assets of UPC Holding or any member of the Borrower Group’s assets, where such violation would or is reasonably likely to have a Material Adverse Effect.

20.           Each Additional Facility W Lender confirms to each Finance Party that:

(a)           it has made its own independent investigation and assessment of the financial condition and affairs of each Obligor and its related entities in connection with its participation in the Credit Agreement and has not relied on any information provided to it by a Finance Party in connection with any Finance Document; and

(b)           it will continue to make its own independent appraisal of the creditworthiness of each Obligor and its related entities while any amount is or may be outstanding under the Credit Agreement or any Additional Facility Commitment is in force.

21.           Each of the Additional Facility W Lenders agrees that without prejudice to Clause 26.3 (Procedure for novations) of the Credit Agreement, each New Lender (as defined in the Novation Certificate referred to below) shall become, by the execution by the Facility Agent

of a Novation Certificate substantially in the form of Schedule 3 to this Agreement, bound by the terms of this Agreement as if it were an original party hereto as an Additional Facility W Lender and shall acquire the same rights and assume the same obligations towards the other parties to this Agreement as would have been acquired and assumed had the New Lender been an original party to this Agreement as an Additional Facility W Lender.

22.           The prior consent of UPC Broadband is required for any assignment, transfer or novation in respect of this Facility W (unless to an Additional Facility W Lender or an Affiliate of an Additional Facility W Lender but without prejudice to clause 26.2(a) of the Credit Agreement), provided that:

(a)           UPC Broadband’s consent must not be unreasonably withheld or delayed;

(b)           the consent of UPC Broadband to an assignment, transfer or novation must not be withheld solely because the assignment, novation or transfer may result in an increase to the Mandatory Cost;

(c)           the prior consent of UPC Broadband is not required when (i) the assignment, novation or transfer of an Additional Facility W Lender’s rights and or obligations is to an Affiliate or Related Fund of that Additional Facility W Lender or (ii) an Event of Default is outstanding;

(d)           nothing in this paragraph 23 restricts the ability of any Additional Facility W Lender to enter into any sub-participation or other arrangement with any third party relating to the Finance Documents which does not transfer to that third party any obligation and/or legal or equitable interest in any of the rights arising under the Credit Agreement.

23.           The Facility Office and address for notices of each Additional Facility W Lender for the purposes of Clause 32.2 (Addresses for notices) of the Credit Agreement will be that notified by each Additional Facility W Lender to the Facility Agent.

24.           This Agreement and any non-contractual obligations arising out of or in connection with it are governed by English law.

25.           This Agreement may be executed in any number of counterparts, and by each party on separate counterparts.  Each counterpart is an original, but all counterparts shall together constitute one and the same instrument.  Delivery of an executed counterpart signature page of this Agreement by e-mail (PDF) or telecopy shall be as effective as delivery of a manually executed counterpart of this Agreement.
