Independent assurance report to the directors of MTN Group Limited

We have been engaged by the directors of MTN Group Limited (MTN) to perform an independent assurance engagement in respect of selected identified sustainable development information included in MTN's 2012 integrated annual report for the year ended 31 December 2012 (the report). This report is produced in accordance with the terms of our contract with MTN dated 5 December 2012.

Independence and expertise

We have complied with the International Federation of Accountants' Code of Ethics for Professional Accountants, which includes comprehensive independence and other requirements founded on fundamental principles of integrity, objectivity, and professional competence and due care, confidentiality and professional behaviour. Our engagement was conducted by a team of environmental and assurance specialists with experience in sustainability reporting.

Scope and subject mattter

The subject matter of our engagement is the Group level data, and the related level of assurance that we are required to provide are as follows:

Limited assurance

The following identified sustainable development information in the report was selected for an expression of limited assurance:

We refer to this information as the "subject matter selected for limited assurance".

We have not carried out any work on data reported for prior reporting periods, nor have we performed work in respect of future projections and targets. We have not conducted any work outside of the agreed scope and therefore restrict our opinion to the subject matter selected for limited assurance.

Respective responsibilities of the directors and PricewaterhouseCoopers Inc.

MTN's directors are responsible for the selection, preparation and presentation of the subject matter selected for limited assurance in accordance with MTN's internally defined procedures set out in the definitions for assured sustainability key performance indicators on page 102 (the "reporting criteria") and for the development of the reporting criteria. The directors are also responsible for such internal control as the directors determine is necessary to enable the preparation of the subject matter selected for limited assurance that are free from material misstatements, whether due to fraud or error.

Our responsibility is to form an independent conclusion, based on our limited assurance procedures, on whether anything has come to our attention to indicate that the subject matter selected for limited assurance is not stated, in all material respects, in accordance with the reporting criteria.

This report, including the conclusions, has been prepared solely for the directors of MTN as a body, to assist the directors in reporting on MTN's sustainable development performance and activities. We permit the disclosure of this report within the report for the year ended 31 December 2012, to enable the directors to demonstrate they have discharged their governance responsibilities by commissioning an independent assurance report in connection with the report. To the fullest extent permitted by law, we do not accept or assume responsibility to anyone other than the directors as a body and MTN for our work or this report save where terms are expressly agreed and with our prior consent in writing.

Assurance work performed

We conducted our assurance engagement in accordance with the International Standard on Assurance Engagements 3000 Assurance Engagements other than Audits or Reviews of Historical Financial Information issued by the International Auditing and Assurance Standards Board (ISAE 3000). This standard requires that we comply with ethical requirements and plan and perform the assurance engagement to obtain limited assurance on the subject matter selected for limited assurance as per the terms of our engagement.

Our procedures relating to the subject matter selected for limited assurance primarily comprised:

• reviewing the processes that MTN has in place for determining the subject matter selected for limited assurance included in the report;
• obtaining an understanding of the systems used to generate, aggregate and report the subject matter selected for limited assurance;
• conducting interviews with management at corporate head office;
• evaluating the data generation and reporting processes against the reporting criteria;
• performing key controls testing and testing the accuracy of data reported on a sample basis at two operating companies (OPCOs) material to Group reported data for the subject matter selected for limited assurance; and
• reviewing the consistency between the subject matter selected for limited assurance and related statements in MTN's report.

The procedures selected depend on our judgement, including the assessment of the risk of material misstatement of the subject matter selected for limited assurance, whether due to fraud or error. In making those risk assessments, we consider internal control relevant to MTN's preparation of the subject matter selected for limited assurance in order to design procedures that are appropriate in the circumstances.

We believe that the evidence we have obtained is sufficient and appropriate to provide a basis for our conclusions.

Inherent limitations

Non-financial performance information is subject to more inherent limitations than financial information, given the characteristics of the subject matter and the methods used for determining, calculating, sampling and estimating such information. The absence of a significant body of established practice on which to draw allows for the selection of different but acceptable measurement techniques which can result in materially different measurements and can impact comparability. Qualitative interpretations of relevance, materiality and the accuracy of data are subject to individual assumptions and judgements. The precision of different measurement techniques may also vary. Furthermore, the nature and methods used to determine such information, as well as the measurement criteria and the precision thereof, may change over time. It is important to read the report in the context of the reporting criteria.

In particular, where the information relies on factors derived by independent third parties, our assurance work has not included examination of the derivation of those factors and other third party information.

Conclusion

Based on the results of our procedures, nothing has come to our attention that causes us to believe that the subject matter selected for limited assurance for the year ended
31 December 2012, has not been prepared, in all material respects, in accordance with the reporting criteria.

Other matter

The maintenance and integrity of MTN's website is the responsibility of MTN's management. Our procedures did not involve consideration of these matters and, accordingly we accept no responsibility for any changes to either the information in the report or our independent assurance report that may have occurred since the initial date of presentation on the MTN website.
