BACKGROUND AND CONSENT SOLICITATIONS Following the announcement of its voluntary recommended conditional public cash takeover on 28 February 2018, on 4 May 2018, DK Telekommunikation ApS acquired shares representing more than 90 per cent. of the total share capital and all voting rights of the Issuer (the "Change of Control"). On 4 May 2018, DK Telecommunication ApS announced its intention to squeeze out the remaining 9 per cent. of the Issuer's share capital held by minority shareholders by early June 2018. Once the squeeze-out is settled, it will establish a permanent capital structure. Subject to market conditions, this is intended to be as follows: Existing unsecured notes of the Issuer (including the 2022 Notes and the 2023 Notes) or up to a 1.0 billion backstop facility at the level of the Issuer; - 1 -

3.9 billion Term Loan B with indicative maturity of 7 years ("TLB") at the level of the Issuer; 1.4 billion capital market issuances at the level of an intermediate holding company named DKT Finance ApS; Unfunded ancillary facilities (RCF and Capex) amounting to 600 million; and 2.7 billion of equity. As security for the Issuer's obligations under the TLB and the RCF and Capex Facilities, the Issuer will grant security over the shares in each of the material companies that it owns, its material bank accounts and material intra-group receivables. In addition, guarantees in respect of the Issuer's obligations will also be granted by some of the Issuer's group companies and certain holding companies thereof (together the "Guarantors") and by DK Telekommunikation ApS. As security for its obligations under the guarantees, each of the Guarantors will, inter alia, grant security over its material bank accounts and intra-group receivables and security will also be granted over the shares in each Guarantor. DK Telekommunikation ApS will grant security over its material bank accounts, material intra-group receivables and over its shares in the Issuer. In addition, pursuant to public announcements and/or confirmations in writing (the "Ratings Announcements") to the Issuer, the Notes relating to each Series have been downgraded (the "Ratings Downgrade") since 4 May 2018 as follows: Series Fitch Ratings Ltd ("Fitch") Moody's Investors Service España, S.A. ("Moody's") Standard & Poor's Ratings Services, a division of The McGraw- Hill Companies, Inc. ("S&P") From To From To From To 2022 Notes BBB- BB- Baa3 B1 BBB- B+ 2023 Notes BBB- BB- Baa3 B1 BBB- B+ Each of Fitch, Moody's and S&P has confirmed in each relevant Ratings Announcement that the Ratings Downgrade resulted, in whole or in part, from the occurrence of the Change of Control. As a result of the Change of Control and the Ratings Downgrade (together, a "Put Event"), the Issuer has given notice (the "Put Event Notice") to the holders of the Notes of each Series that a Put Event has occurred, pursuant to the Conditions with respect to the 2022 Notes and the 2023 Notes. As a result of a Put Event occurring with respect to each Series, each Noteholder has the option to require the Issuer to redeem or, at the Issuer's option, purchase (or procure the purchase of) its Notes on 30 June 2018 (the "Put Date") at their principal amount together with interest accrued to but excluding the date of redemption or purchase (the "Put Option"). As 30 June 2018 is not a Payment Business Day, pursuant to the Conditions of each Series, settlement of the redemption of the Notes in respect of which the Put Option has been exercised will take place on the next Payment Business Day (being 2 July 2018). Through the Consent Solicitations, the Issuer is inviting the Noteholders to consent to waive the Put Option rights contained in the Conditions of each relevant Series. The Issuer has invited holders of the Notes of each Series (each such invitation a "Consent Solicitation") to consent to the approval, by Extraordinary Resolution at the relevant Meeting, of the wavier of the Put Option rights contained in the Conditions relating to the relevant Series as described in paragraph 1 of the relevant Extraordinary Resolution as set out below, all as further described in the Consent Solicitation Memorandum (as defined in paragraph 2 of the Extraordinary Resolutions set out below).

A Direct Participant or beneficial owner of the Notes not wishing to attend and vote at the relevant Meeting in person may either deliver its valid voting certificate(s) to the person whom it wishes to attend on its behalf or the Direct Participant may (or the beneficial owner of the Notes may arrange for the relevant Direct Participant on its behalf to) or give a voting instruction (by giving voting and blocking instructions to Euroclear or Clearstream, Luxembourg (a "Euroclear/Clearstream Instruction") in accordance with the procedures of Euroclear or Clearstream, Luxembourg, as applicable) requiring a Paying Agent to include the votes attributable to its Notes in a block voting instruction issued by the Paying Agent for the relevant Meeting or any adjourned such Meeting, in which case the Paying Agent shall appoint the Tabulation Agent as proxy to attend and vote at such Meeting in accordance with such Direct Participant or beneficial owner's instructions.

Notwithstanding the above, Noteholders will be able to submit separate electronic instructions in accordance with the terms of the Put Event Notice to exercise the Put Option with respect to their Notes. In the event that the relevant Extraordinary Resolution(s) are not passed, the Notes in respect of which the Put Option has been exercised will remain blocked until they are redeemed pursuant to the relevant Conditions. 3. The quorum required at any Meeting is one or more persons present holding Notes or voting certificates or being proxies or representatives and holding or representing not less than one more than half of the aggregate principal amount of the outstanding Notes of the relevant Series.

4. Every question submitted to a Meeting shall be decided in the first instance by a show of hands. Unless a poll is (before or at the time that the result is declared) demanded by the Chairman, the Issuer or any Noteholder present or proxy or representative holding not less than one fiftieth of the principal amount of the relevant Series for the time being outstanding, a declaration by the Chairman that a resolution has been passed or carried by a particular majority or lost or not carried by a particular majority shall be conclusive evidence of the fact without proof of the number or proportion of the votes recorded in favour of or against the relevant Extraordinary Resolution. At each Meeting: (i) on a show of hands every person who is present in person and produces a voting certificate or is a proxy or representative shall have one vote; and (ii) on a poll every person who is so present shall have one vote in respect of each EUR/GBP 1 (as applicable) in principal amount of the outstanding Notes of the relevant Series so represented by the voting certificate or in respect of which that person is a proxy or representative. 5. To be passed at the relevant Meeting, an Extraordinary Resolution requires a majority in favour consisting of not less than three-quarters of the votes cast.
