PARETEUM CORPORATION

to be effected

by way of a scheme of arrangement

under Part 26 of the Companies Act 2006

Result of Shareholder Meetings

On 7 June 2018, the boards of Artilium Plc and Pareteum Corporation announced that they had reached agreement on the terms of a recommended share and cash offer pursuant to which Pareteum will acquire the entire issued and to be issued ordinary share capital of Artilium not already owned by Pareteum (the "Acquisition"), which will be effected by means of a Court-sanctioned scheme of arrangement under Part 26 of the Companies Act 2006 ("Scheme").

The Board of Artilium is pleased to announce that at the Court Meeting and the General Meeting convened in relation to the proposed Scheme held earlier today all resolutions proposed, details of which are set out in the notices of each meeting contained in the scheme document dated 20 August 2018 (the "Scheme Document"), were passed by the requisite majorities and accordingly the Scheme was approved.

A summary of the voting results is set out below.

Court Meeting

At the Court Meeting, a majority in number of the Scheme Shareholders present and voting (and entitled to vote), either in person or by proxy, representing over 75 per cent. in value of the Scheme Shares held by such Scheme Shareholders, voted in favour of the Scheme and, accordingly, the resolution to approve the Scheme was duly passed on a poll vote. Details of the votes cast are as follows:

*A withheld vote is not a vote in law and, accordingly, is not counted in the calculation of the proportion of votes "For" and "Against" the resolution concerned. Any proxy appointments which gave discretion to the Chairman have been included in the vote "For" total.

** Neither Bart Weijermars nor any person acting in concert with him or any person connected with him shall be entitled to vote in respect of resolution 4 pursuant to Rule 16.2 of the

City Code on Takeovers and Mergers.

The total number of Artilium Ordinary Shares in issue at the Voting Record Time was 355,154,922.

Next Steps and Expected Timetable

Completion of the Acquisition remains conditional on the satisfaction or waiver of the remaining Conditions set out in the Scheme Document, including the Court's sanction of the Scheme and the delivery of a copy of the Court Order to the Registrar of Companies.

On the basis of the current indicative timetable for the Scheme and subject to the Court sanction of the Scheme, the Scheme is expected to become Effective on 1 October 2018 (the "Effective Date"), the last day of dealings in, and for registration of transfers of, Artilium Ordinary Shares will be Friday 28 September 2018. At 7.00 a.m. on 2 October 2018, the admission of Artilium Ordinary Shares to trading on AIM is expected to be cancelled.

Overseas shareholders

Unless otherwise determined by Artilium and Pareteum or required by the Takeover Code, and permitted by applicable law and regulation, the Acquisition will not be made available, directly or indirectly, in, into or from a Restricted Jurisdiction where to do so would violate the laws in that jurisdiction and no person may vote in favour of the Scheme by any such use, means, instrumentality or from within a jurisdiction if to do so would constitute a violation of the laws of that jurisdiction.

Accordingly, copies of the Scheme Document and all documents relating to the Acquisition are not being, and must not be, directly or indirectly, mailed or otherwise forwarded, distributed or sent in, into or from a jurisdiction where to do so would violate the laws in that jurisdiction, and persons receiving the Scheme Document and all other documents relating to the Acquisition (including custodians, nominees and trustees) must not mail or otherwise distribute or send them in, into or from jurisdictions where to do so would violate the laws in that jurisdiction.

It is the responsibility of each Overseas Holder to satisfy himself as to the full observance of the laws and regulatory requirements of the relevant jurisdiction in connection with the Acquisition, including obtaining any governmental, exchange control or other consents which may be required, or the compliance with other necessary formalities which are required to be observed and the payment of any issue, transfer or other taxes due in such jurisdiction.

The Scheme Document and its accompanying documents have been prepared in connection with a proposal in relation to a scheme of arrangement pursuant to, and for the purpose of complying with, English law and the Takeover Code and the information disclosed may not be the same as that which would have been disclosed if these documents had been prepared in accordance with the laws of jurisdictions outside England and Wales.

The availability of New Pareteum Shares under the Acquisition to Artilium Shareholders who are not resident in the United Kingdom may be affected by the laws of the relevant jurisdictions in which they are resident. Further details are set out in paragraph 19 of Part 2 (Explanatory Statement) of the Scheme Document.

Notice to US investors

The New Pareteum Shares are expected to be issued in the United States in reliance upon the exemption from the registration requirements of the US Securities Act provided by section 3(a)(10) thereof.

For the purposes of qualifying for the exemptions from the registration requirements of the US Securities Act afforded by section 3(a)(10), Artilium will advise the Court through counsel that the Court's sanction of the Scheme will be relied upon by Pareteum as an approval of the Scheme following a hearing on the fairness of the terms and conditions of the Scheme to Artilium Shareholders at which hearing all such shareholders are entitled to appear in person or through counsel to support or oppose the sanctioning of the Scheme and with respect to which notification has been given to all Artilium Shareholders.

Scheme Shareholders (whether or not US persons) who are or will be affiliates (within the meaning of the US Securities Act) of Artilium or Pareteum prior to, or of Pareteum after, the Effective Date will be subject to certain restrictions on transfers of the New Pareteum Shares received pursuant to the Scheme. Otherwise, the New Pareteum Shares generally should not be treated as "restricted securities" within the meaning of Rule 144(a)(3) under the US Securities Act and persons who receive securities under the Scheme (other than affiliates) may resell them without restriction under the US Securities Act. For a description of these and certain further restrictions on offers, sales and transfers of the New Pareteum Shares and the distribution of the Scheme Document, and additional information applicable to US shareholders, see paragraph 19 of Part 2 (Explanatory Statement) of the Scheme Document.

The receipt of New Pareteum Shares pursuant to the Acquisition by a US Shareholder may be a taxable transaction for US federal income tax purposes and under applicable state and local, as well as foreign and other, tax laws. Each Artilium Shareholder is urged to consult his independent professional adviser immediately regarding the tax consequences of the Acquisition.

It may be difficult for US Shareholders to enforce their rights and claims arising out of the US federal securities laws, Artilium is located in countries other than the United States, and some or all of its officers and directors may be residents of countries other than the United States. US Shareholders may not be able to sue a non-US company or its officers or directors in a non-US court for violations of the US securities laws. Further, it may be difficult to compel a non-US company and its affiliates to subject themselves to a US court's judgment.

None of the securities referred to in the Scheme Document have been approved or disapproved by the SEC, any state securities commission in the United States or any other US regulatory authority, nor have such authorities passed upon or determined the adequacy or accuracy of the information contained in the Scheme Document. Any representation to the contrary is a criminal offence in the United States.

The financial information included in, or incorporated by reference into, the Scheme Document has been prepared in accordance with the International Financial Reporting Standards ("IFRS") as adopted by the European Union and thus may not be comparable to financial information of US companies or companies whose financial statements are prepared in accordance with generally accepted accounting principles in the United States.

Disclosure requirements of the Code

Under Rule 8.3(a) of the Code, any person who is interested in 1 per cent. or more of any class of relevant securities of an offeree company or of any securities exchange offeror (being any offeror other than an offeror in respect of which it has been announced that its offer is, or is likely to be, solely in cash) must make an Opening Position Disclosure following the commencement of the offer period and, if later, following the announcement in which any securities exchange offeror is first identified. An Opening Position Disclosure must contain details of the person's interests and short positions in, and rights to subscribe for, any relevant securities of each of: (i) the offeree company and (ii) any securities exchange offeror(s). An Opening Position Disclosure by a person to whom Rule 8.3(a) applies must be made by no later than 3.30 p.m. (London time) on the 10th Business Day following the commencement of the offer period and, if appropriate, by no later than 3.30 p.m. (London time) on the 10th Business Day following the announcement in which any securities exchange offeror is first identified. Relevant persons who deal in the relevant securities of the offeree company or of a securities exchange offeror prior to the deadline for making an Opening Position Disclosure must instead make a Dealing Disclosure.

Under Rule 8.3(b) of the Code, any person who is, or becomes, interested in 1 per cent. or more of any class of relevant securities of the offeree company or of any securities exchange offeror must make a Dealing Disclosure if the person deals in any relevant securities of the offeree company or of any securities exchange offeror. A Dealing Disclosure must contain details of the dealing concerned and of the person's interests and short positions in, and rights to subscribe for, any relevant securities of each of: (i) the offeree company and (ii) any securities exchange offeror, save to the extent that these details have previously been disclosed under Rule 8. A Dealing Disclosure by a person to whom Rule 8.3(b) applies must be made by no later than 3.30 p.m. (London time) on the Business Day following the date of the relevant dealing.

If two or more persons act together pursuant to an agreement or understanding, whether formal or informal, to acquire or control an interest in relevant securities of an offeree company or a securities exchange offeror, they will be deemed to be a single person for the purpose of Rule 8.3.

Opening Position Disclosures must also be made by the offeree company and by any offeror, and Dealing Disclosures must also be made by the offeree company, by any offeror and by any persons acting in concert with any of them (see Rules 8.1, 8.2 and 8.4).

Details of the offeree and offeror companies in respect of whose relevant securities Opening Position Disclosures and Dealing Disclosures must be made can be found in the Disclosure Table on the Takeover Panel's website at www.thetakeoverpanel.org.uk, including details of the number of relevant securities in issue, when the offer period commenced and when any offeror was first identified. You should contact the Takeover Panel's Market Surveillance Unit on +44 (0)20 7638 0129 if you are in any doubt as to whether you are required to make an Opening Position Disclosure or a Dealing Disclosure.
