VODAFONE ANNOUNCES COMMENCEMENT OF OFFER TO PURCHASE OUTSTANDING NOTES OF NARA CABLE FUNDING LIMITED AND ONO FINANCE II PLC

NOT FOR DISTRIBUTION TO ANY PERSON LOCATED OR RESIDENT IN ANY JURISDICTION WHERE IT IS UNLAWFUL TO DISTRIBUTE THIS DOCUMENT (SEE “OFFER AND DISTRIBUTION RESTRICTIONS” BELOW).

LONDON, July 30, 2014 — Vodafone Group Plc (NASDAQ: VOD) announced today that Vodafone Holdings Europe S.L.U. (“VHESL”) has commenced a tender offer (the “Offer”) to repurchase for cash any and all of the outstanding below listed notes (the “Notes”) of Nara Cable Funding Limited (“Nara Cable”) and of ONO Finance II plc (together with Nara Cable, the “Issuers”).

The Issuers are stand-alone entities which issued the Notes to provide loans to Cableuropa S.A.U. VHESL is the parent of Vodafone Espana S.A.U. which has recently completed the acquisition of Grupo Corporativo ONO, S.A., the parent company of Cableuropa S.A.U., resulting in a Change of Control event under and as defined in the indentures governing the Notes.

The Offer complies with the Change of Control covenant set forth in the Indentures and VHESL is offering a premium over the 101% required thereunder.

Capitalized terms used in this announcement and not otherwise defined have the meanings ascribed to them in the Offer to Purchase dated July 30, 2014 (the “Offer to Purchase”).  The Offer will be made solely by, and subject to terms and conditions set forth in, the Offer to Purchase, which is available to holders of Notes directly from the Information and Tender Agent, subject to the offer and distribution restrictions set out below and more fully described in the Offer to Purchase.  VHESL notes that there are certain conditions to the completion of the Offer to Purchase and offers no assurances that the Offer to Purchase will be completed.

Holders of relevant Notes that are validly tendered and not validly withdrawn at or prior to the Expiration Date (5:00 p.m., New York City time for the dollar denominated Notes and 5:00 p.m., London time for the euro denominated Notes, on August 28, 2014) and accepted for purchase will receive the relevant Tender Price as set forth in the table below, plus Accrued Interest to but not including, September 4, 2014 (the “Settlement Date”).

If a broker, dealer, commercial bank, trust company or other nominee holds Notes, such nominee may have earlier deadlines for accepting the Offer than the Expiration Date. Holders should promptly contact the broker, dealer, commercial bank, trust company or other nominee that holds their Notes to determine its deadline or deadlines. The Offer is open to all registered Holders, subject to terms and conditions set forth in the Offer to Purchase.

(1) Does not include Accrued Interest, which will be paid up to, but excluding, the Settlement Date.

(2) Intended to reflect more closely market based pricing. Such pricing is materially in excess of the 101% purchase price which is required by the Change of Control provisions of the Indentures. It should also be noted that the Tender Prices reflect a premium to the call prices of the Notes in either December 2014 or January 2015, as the case may be, which is intended to capture the lower costs of funding for the Company compared to the coupon on the Notes.

For further information:

A complete description of the terms and conditions are set out in the Offer to Purchase.  Further details on the transaction can be obtained from:
