BASE PROSPECTUS N.V. NEDERLANDSE GASUNIE (incorporated with limited liability in the Netherlands and having its corporate seat in Groningen, the Netherlands) EUR 7,500,000,000 Euro Medium Term Note Programme Due up to 50 years from the date of Issue Under this Euro Medium Term Note Programme (the "Programme"), N.V. Nederlandse Gasunie (the "Issuer" or "Gasunie", which term includes, where the context permits, Gasunie's subsidiaries) may from time to time issue notes (the "Notes") denominated in any currency agreed between the Issuer and the relevant Dealer (as defined below). The aggregate nominal amount of all Notes from time to time outstanding under the Programme will not exceed € 7,500,000,000 (or its equivalent in other currencies calculated as described in the Programme Agreement described herein), subject to increase as described herein. The Notes may be issued on a continuing basis to one or more of the Dealers specified under "Overview" and any additional Dealer appointed under the Programme from time to time by the Issuer (each a "Dealer" and together the "Dealers"), which appointment may be for a specific issue or on an ongoing basis. References in this base prospectus (the "Prospectus") to the relevant Dealer shall, in the case of an issue of Notes being (or intended to be) subscribed by more than one Dealer, be to all Dealers agreeing to subscribe such Notes. 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. Application has been made to Euronext Amsterdam N.V. ("Euronext Amsterdam") to allow Notes issued under the Programme, during the period of 12 months from the date of this Prospectus, to be admitted to trading and to be listed on Euronext in Amsterdam. The Issuer may request the AFM to provide competent authorities in additional countries which are parties to the Agreement on the European Economic Area of 17 March 2003 with a certificate of approval attesting that this Prospectus has been drawn up in accordance with the Wft and related regulations which implement the Prospectus Directive in Dutch law. As used herein, the expression "Prospectus Directive" means Directive 2003/71/EC (as amended, including by Directive 2010/73/EU), and includes any relevant implementing measure in a relevant Member State of the European Economic Area. References in this Prospectus to Notes being listed (and all related references) shall mean that such Notes have been admitted to trading and listing on Euronext in Amsterdam. Euronext in Amsterdam is a regulated market for the purposes of Directive 2004/39/EC (the Markets in Financial Instruments Directive). The Programme provides that Notes may be listed or admitted to trading, as the case may be, on such other or further stock exchanges, automated trading systems, over the counter or other securities markets as may be agreed between the Issuer and the relevant Dealer. The Issuer may also issue unlisted Notes and/or Notes not admitted to trading on any market. The Issuer may agree with any Dealer that Notes may be issued in a form not contemplated by the Terms and Conditions (as defined below) of the Notes herein, in which event a prospectus supplement or an individual (drawdown or base) prospectus, if appropriate, will be made available which will describe the effect of the agreement reached in relation to such Notes and, where appropriate, which will be subject to the prior approval by the AFM. The full terms and conditions of each Tranche of Notes are constituted by the Terms and Conditions of the Notes as set out in full in this Prospectus in "Terms and conditions of the Notes" (the "Terms and Conditions") which constitute the basis of all Notes to be offered under the Programme, together with the Final Terms applicable to the relevant issue of Notes, which apply and/or do not apply and/or supplement the Terms and Conditions of the Notes in the manner required to reflect the particular terms and conditions applicable to the relevant Series of Notes (or Tranche thereof). 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 Global Ratings ("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. Amounts payable on Notes may be calculated by reference to LIBOR, EURIBOR or EONIA as specified in the relevant Final Terms. As at the date of this Base Prospectus, the administrator of LIBOR, ICE Benchmark Administration (“IBA”), is included in ESMA’s register of administrators under Article 36 of the Regulation (EU) No. 2016/1011 (the “Benchmarks Regulation”). The European Money Markets Institute (“EMMI”), the administrator of EURIBOR and EONIA, does not appear on the register of administrators and benchmarks established and maintained by ESMA pursuant to Article 36 of the Benchmarks Regulation. Under the Benchmarks Regulation the EMMI is currently required to obtain an authorisation/registration, but as far as the Issuer is aware, the transitional provisions in Article 51 of the Benchmarks Regulation apply. 2 Arranger NATWEST MARKETS Dealers ABN AMRO COMMERZBANK BNP PARIBAS ING CRÉDIT AGRICOLE CIB NATWEST MARKETS MUFG RABOBANK This Prospectus will be published in electronic form on the Issuer's website https://www.gasunie.nl/en/investor-relations/debt-programmes/european-medium-term- notes-emtn-programme on 6 August 2018, (the "Publication Date").
