Notes may be distributed by way of a public offer or private placements and, in each case, on a syndicated or non-syndicated basis. The method of distribution of each relevant series of Notes (a "Series") or tranche thereof (a "Tranche") will be stated in the applicable Final Terms (the "Final Terms"). An investment in Notes issued under the Programme involves certain risks. For a discussion of these risks see "Risk Factors". The Authority for the Financial Markets (Autoriteit Financiële Markten, the "AFM"), in its capacity as competent authority under the Financial Supervision Act (Wet op het financieel toezicht, the "Wft"), has approved this Prospectus pursuant to Section 5:2 of the Wft.

Notes issued under the Programme may be rated or unrated. The rating of certain Series of Notes to be issued under the Programme may be specified in the applicable Final Terms. Where an issue of Notes is rated, its rating will not necessarily be the same as the rating applicable to the Programme. In general, European regulated investors are restricted from using a rating for regulatory purposes if such rating is not issued by a credit rating agency established in the European Community and registered under Regulation (EC) No. 1060/2009 (as amended) (the "CRA Regulation") unless the rating is provided by a credit rating agency operating in the European Community before 7 June 2010 which has submitted an application for registration in accordance with the CRA Regulation and such registration is not refused. Each of Moody's Investors Service Limited ("Moody's") and Standard & Poor’s Credit Market Services Italy SRL ("S&P") are credit rating agencies established and operating in the European Community prior to 7 June 2010 and have submitted an application for registration in accordance with the CRA Regulation and as of 31 October 2011 they were registered as such. A rating is not a recommendation to buy, sell or hold securities and may be subject to suspension, change or withdrawal at any time by the assigning rating agency. 2 Arranger THE ROYAL BANK OF SCOTLAND Dealers ABN AMRO BARCLAYS BNP PARIBAS COMMERZBANK CRÉDIT AGRICOLE CIB ING MUFG RABOBANK INTERNATIONAL THE ROYAL BANK OF SCOTLAND This Prospectus will be published in electronic form on the Issuer's website (http://www.gasunie.nl/en/investor-relations/debt-programmes/european-medium-term- notes-emtn-programme) on 23 December 2014, (the "Publication Date").
