RECOMMENDED ALL-SHARE OFFER

for

Lonmin Plc (“Lonmin”)
by
Sibanye Gold Limited (trading as Sibanye-Stillwater) (“Sibanye-Stillwater”)

to be effected by means of a scheme of arrangement
under Part 26 of the UK Companies Act 2006

Summary
-     The Boards of Sibanye-Stillwater and Lonmin are pleased to announce that they have
      reached agreement on the terms of a recommended all-share offer pursuant to which
      Sibanye-Stillwater, and/or a wholly-owned subsidiary of Sibanye-Stillwater, will acquire the
      entire issued and to be issued ordinary share capital of Lonmin (the “Offer”). It is proposed
      that the Offer will be effected by means of a scheme of arrangement between Lonmin and
      the Lonmin Shareholders under Part 26 of the UK Companies Act.

-     Under the terms of the Offer, each Lonmin Shareholder will be entitled to receive:

            for each Lonmin Share                   0.967 New Sibanye-Stillwater Shares

-     Based on the 30 trading day volume weighted average price of R18.67 of Sibanye-Stillwater
      Shares on the Johannesburg Stock Exchange for the period ended 13 December 2017
      (being the last Business Day prior to the date of this Announcement) and the exchange rate
      on that date being R18.056:£1, the Offer values each Lonmin Share at 100.0 pence and
      values the existing issued ordinary share capital of Lonmin at approximately £285 million
      and represents a premium of approximately:

      -      57 per cent. to the closing price per Lonmin Share of 63.8 pence on 13 December
             2017; and




                                                1
     -      41 per cent. to the 30 trading day volume weighted average price per Lonmin Share
            for the period ended 13 December 2017 of 71.1 pence.

-    The Exchange Ratio of the Offer has been determined using the 30 trading day volume
     weighted average price for Sibanye-Stillwater to smooth out the daily movements.

-    Based on the closing price of R16.11 of a Sibanye-Stillwater Share on the Johannesburg
     Stock Exchange on 13 December 2017 and applying the same exchange rate, the Offer
     values each Lonmin Share at 86.3 pence and represents a premium of approximately 35
     per cent. to the closing price per Lonmin Share of 63.8 pence on 13 December 2017.

?    Following completion of the Acquisition, Lonmin Shareholders will hold approximately 11.3
     per cent. of the Enlarged Sibanye-Stillwater Group and Sibanye-Stillwater Shareholders will
     hold approximately 88.7 per cent. of the Enlarged Sibanye-Stillwater Group.

?    The Exchange Ratio assumes that Lonmin Shareholders will not receive any dividend after
     the date of this Announcement. If any dividend or other distribution is authorised, declared,
     made or paid in respect of Lonmin Shares on or after the date of this Announcement and
     prior to the Effective Date, the Exchange Ratio will be adjusted downwards on an equivalent
     basis to reflect the amount of any such dividend or other distribution.

-    The Sibanye-Stillwater Group is a South Africa domiciled global precious metals mining
     group with its primary listing on the Johannesburg Stock Exchange and an ADR program
     traded on the New York Stock Exchange. The Sibanye-Stillwater Group owns and operates
     a mix of gold and PGM mines and projects throughout South Africa, Zimbabwe and the
     United States. In addition to its mining activities, the Sibanye-Stillwater Group owns and
     manages significant gold extraction and processing facilities. Globally, the Sibanye-
     Stillwater Group is a major producer of palladium and platinum and features among the
     world’s top ten gold producing companies. In line with the Sibanye-Stillwater Group’s
     strategy to grow its precious metals business by enhancing and sustaining its position as a
     sustainable, strong dividend-paying company, the Sibanye-Stillwater Group has completed
     three separate transactions to build its PGM operations and capabilities, specifically via
     acquisitions of the platinum assets of the Rustenburg Operations and Aquarius Platinum in
     2016 and Stillwater in 2017. The Sibanye-Stillwater Group’s vision is to achieve value
     creation for all stakeholders through mining its multi-commodity resources in a safe and
     healthy environment.

-    The Lonmin Group is a major mine-to-market producer of PGMs with core operations in
     South Africa. It produces PGMs predominantly used in many industrial applications as well
     as in jewellery and investment, with saleable by-products including gold, copper, nickel,
     chrome and cobalt. The Lonmin Group is a major primary producer of PGMs worldwide.
     Lonmin Shares are admitted to listing on the premium listing segment of the Official List and
     to trading on the Main Market of the London Stock Exchange and have a secondary listing
     on the Main Board of the Johannesburg Stock Exchange. Lonmin also has an ADR program
     traded on the Over-The-Counter market in the United States. The Lonmin Group has total
     assets of US$2,018 million (as at 30 September 2016) and resources of 180.6Moz (3PGE +
     Au) and 31.7Moz (3PGE + Au) of reserves (as at 30 September 2016).

Benefits to Lonmin and Lonmin Shareholders
-    The Board of Lonmin believes that the Offer is in the best interests of Lonmin Shareholders
     and all other stakeholders of Lonmin and provides Lonmin with a comprehensive and
     sustainable solution to the adverse challenges it faces. The combination of Sibanye-




                                               2
     Stillwater and Lonmin creates a larger and more resilient company, with greater
     geographical and commodity diversification, that is better able to withstand short-term
     commodity price and foreign exchange volatility. The Offer also allows Lonmin Shareholders
     to participate in:

     -       the growth and value creation opportunities of the Enlarged Sibanye-Stillwater
             Group;

     -       the benefits from the realisation of synergies from the combination of Sibanye-
             Stillwater and Lonmin; and

     -       exposure to any long-term recovery in the fundamentals of the PGM sector.

Benefits to the Sibanye-Stillwater Group and Sibanye-Stillwater Shareholders
-    The Board of Sibanye-Stillwater believes that the Acquisition is compelling and value
     accretive for Sibanye-Stillwater Shareholders and is a logical step in executing its PGM
     strategy. By combining Sibanye-Stillwater’s existing, and contiguous, South African PGM
     assets with Lonmin's operations, including Lonmin's processing facilities, Sibanye-Stillwater
     will be able to unlock operational synergies and become a fully integrated PGM producer in
     South Africa.

-    In particular, Sibanye-Stillwater has identified the following principal benefits to the Sibanye-
     Stillwater Group from the Acquisition:

     -       consistency with Sibanye-Stillwater’s strategy;

     -       access to its own processing facilities in South Africa;

     -       realisation of significant synergies between Sibanye-Stillwater and Lonmin's
             contiguous assets; and

     -       potential upside from developmental projects.

-    Sibanye-Stillwater has developed a conservative Lonmin operating plan, which is not
     contingent on the development of new major capital projects and therefore limits downside
     risk while providing full upside optionality in a higher South African Rand PGM price
     environment.

Recommendation by the Lonmin Directors

-    The Lonmin Directors, who have been so advised by Gleacher Shacklock, J.P. Morgan
     Cazenove and Moshe Capital as to the financial terms of the Offer, consider the terms of the
     Offer to be fair and reasonable. In providing advice to the Lonmin Directors, Gleacher
     Shacklock, J.P. Morgan Cazenove and Moshe Capital have taken into account the
     commercial assessments of the Lonmin Directors.

-    The Lonmin Directors consider the terms of the Offer to be in the best interests of Lonmin
     Shareholders as a whole and intend unanimously to recommend that Lonmin Shareholders
     vote in favour of the Scheme at the Court Meeting and the resolutions to be proposed at the
     Lonmin General Meeting which is to be convened to approve the Offer, as the Lonmin
     Directors have irrevocably undertaken to Sibanye-Stillwater to do in respect of their own
     beneficial shareholdings in Lonmin which amount in aggregate to 75,498 Lonmin Shares,
     representing approximately 0.026698 per cent. of the existing issued ordinary share capital
     of Lonmin in issue on 13 December 2017 (being the last Business Day prior to the date of
     this Announcement).



                                                 3
-     Further details of these irrevocable undertakings are set out in Appendix III to this
      Announcement.



Structure of the Offer

-     It is intended that the Offer will be effected by means of a scheme of arrangement under
      Part 26 of the UK Companies Act between Lonmin and Lonmin Shareholders. The Offer will
      be put to Lonmin Shareholders at the Court Meeting and at the Lonmin General Meeting. In
      order to become effective, the Scheme must be approved by a majority in number of the
      Lonmin Shareholders voting at the Court Meeting, either in person or by proxy, representing
      at least 75 per cent. in value of the Lonmin Shares voted. In addition, special resolutions
      implementing the Scheme must be passed by Lonmin Shareholders representing at least 75
      per cent. of the votes cast, either in person or by proxy, at the Lonmin General Meeting.

-     The Offer is also conditional upon Sibanye-Stillwater Shareholders approving the allotment
      and issue of the New Sibanye-Stillwater Shares at the Sibanye-Stillwater Shareholder
      Meeting in accordance with clause 8.2.2 of the Sibanye-Stillwater MOI, by way of an
      ordinary resolution. Sibanye-Stillwater will therefore seek the requisite approvals of the
      Sibanye-Stillwater Shareholders for the allotment and issue of the New Sibanye-Stillwater
      Shares for the purposes of the Offer at the Sibanye-Stillwater Shareholder Meeting which is
      expected to be held at or around the same time as the Lonmin General Meeting, both of
      which will be held as soon as reasonably practicable following the receipt of all the relevant
      clearances from the competition and regulatory authorities, in particular those in South
      Africa and the United Kingdom (or, if applicable, the European Union, in case a referral is
      made to the European Commission pursuant to Article 22 of Council Regulation (EC)
      139/2004) (unless Sibanye-Stillwater and Lonmin otherwise agree).

-     The Offer is subject to the further Conditions set out in Appendix I to this Announcement,
      including the receipt of the relevant clearances from the competition and regulatory
      authorities, in particular those in South Africa and the United Kingdom (or, if applicable, the
      European Union, in case a referral is made to the European Commission pursuant to Article
      22 of Council Regulation (EC) 139/2004), the Licences Condition, the admission of the New
      Sibanye-Stillwater Shares to listing and trading on the Main Board of the Johannesburg
      Stock Exchange and to the full terms and conditions which will be set out in the Scheme
      Document.

-     It is expected that the Scheme will become effective in the second half of 2018, subject to
      the satisfaction or (where applicable) waiver of the Conditions and certain further terms set
      out in Appendix I to this Announcement.

-     The Scheme Document, containing further information about the Offer and notices of the
      Court Meeting and the Lonmin General Meeting, together with the Forms of Proxy, will be
      sent to Lonmin Shareholders in due course around the time that all relevant clearances from
      the competition and regulatory authorities, in particular those in South Africa and the United
      Kingdom (or, if applicable, the European Union, in case a referral is made to the European
      Commission pursuant to Article 22 of Council Regulation (EC) 139/2004), have been
      received. The Scheme Document will be made available in due course by Sibanye-Stillwater
      on its website at www.sibanyestillwater.com/investors/transactions/lonmin and by Lonmin on
      its website at www.lonmin.com/investors/sibanye-stillwater-offer.




                                                 4
-     The Sibanye-Stillwater Circular, containing (amongst other things) the notice of the Sibanye-
      Stillwater Shareholder Meeting (including the resolution to be adopted by the Sibanye-
      Stillwater Shareholders), together with the Forms of Proxy, will be posted to Sibanye-
      Stillwater Shareholders at or around the same time as the Scheme Document is published.
      The Sibanye-Stillwater Circular will be made available in due course by Sibanye-Stillwater
      on its website at www.sibanyestillwater.com/investors/transactions/lonmin and by Lonmin on
      its website at www.lonmin.com/investors/sibanye-stillwater-offer.

Commenting on the Offer, Neal Froneman, Chief Executive Officer of Sibanye-Stillwater, said:

      “The proposed combination with Lonmin positions the Enlarged Sibanye-Stillwater Group as
      a leading mine-to-market producer of PGMs in South Africa. The realisation of significant
      synergies between the operations, which will deliver longer term benefits for all stakeholders
      of both companies is expected to result in this being a value accretive transaction for
      Sibanye-Stillwater Shareholders. The flexibility inherent in the larger regional PGM footprint
      will create a more robust business, better able to withstand volatile PGM prices and
      exchange rates. Furthermore, the sizeable combined resource base, with its pipeline of
      advanced and early stage projects, also offers significant growth and value upside potential
      under appropriate economic and market circumstances.”

Commenting on the Offer, Ben Magara, Chief Executive Officer of Lonmin, said:

      “We believe that this Offer is in the best interests of Lonmin, Lonmin Shareholders and all
      other stakeholders. Lonmin has an enviable mine-to-market business with great mining
      assets, projects and process technology and a resilient workforce. Despite this, Lonmin
      continues to be hamstrung by its capital structure and liquidity concerns. The combination
      with Sibanye-Stillwater provides a stronger platform for Lonmin Shareholders and other
      stakeholders to benefit from the long-term upside potential of an Enlarged Sibanye-
      Stillwater Group with greater geographical and commodity diversification. We unanimously
      recommend this Offer to Lonmin Shareholders.”

This Announcement is for information purposes only. It is not intended to and does not constitute,
or form part of, an offer, invitation or the solicitation of an offer to purchase, otherwise acquire,
subscribe for, sell or otherwise dispose of any securities, or the solicitation of any vote or approval
in any jurisdiction, pursuant to the Offer or otherwise, nor will there be any sale, issuance or
transfer of securities in any jurisdiction in contravention of applicable law.

The Offer will be made solely by means of the Scheme Document which, together with the Forms
of Proxy, will contain the full terms and conditions of the Offer including details of how to vote in
respect of the Offer.

This Announcement has been prepared 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 this Announcement had been prepared in accordance with the laws and regulations of
jurisdictions outside the United Kingdom.

Sibanye-Stillwater will prepare the Sibanye-Stillwater Circular to be distributed to Sibanye-
Stillwater Shareholders. Lonmin will prepare the Scheme Document to be distributed to Lonmin
Shareholders. Sibanye-Stillwater urges Lonmin Shareholders to read the Scheme Document
carefully when it becomes available because it will contain important information in relation to the

Overseas shareholders

The release, publication or distribution of this Announcement in certain jurisdictions may be
restricted by law. Persons who are not resident in the United Kingdom or who are subject to other
jurisdictions should inform themselves of, and observe, any applicable requirements. Any failure to
comply with the applicable requirements may constitute a violation of the laws of any such
jurisdiction.

The Offer relates to shares of a UK company and is proposed to be effected by means of a
scheme of arrangement under the laws of England and Wales. A transaction effected by means of
a scheme of arrangement is not subject to proxy solicitation or tender offer rules under the US
Exchange Act. Accordingly, the Scheme is subject to the disclosure requirements, rules and
practices applicable in the United Kingdom to schemes of arrangement, which differ from the
requirements of US proxy solicitation or tender offer rules. However, if Sibanye-Stillwater were to
elect to implement the Offer by means of a takeover offer, such takeover offer will be made in
compliance with all applicable laws and regulations, including Section 14(e) of the US Exchange
Act and Regulation 14E thereunder. Such a takeover would be made in the United States by
Sibanye-Stillwater and no one else. In addition to any such takeover offer, Sibanye-Stillwater,
certain affiliated companies and the nominees or brokers (acting as agents) may make certain
purchases of, or arrangements to purchase, shares in Lonmin outside such takeover offer during
the period in which such takeover offer would remain open for acceptance. If such purchases or
arrangements to purchase were to be made they would be made outside the United States and
would comply with applicable law, including the US Exchange Act. Any information about such
purchases will be disclosed as required in the UK, will be reported to a Regulatory Information
Service of the UKLA and will be available on the London Stock Exchange website:

The financial information included in this Announcement has been prepared in accordance with
accounting standards applicable in the UK and South Africa 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.

Unless otherwise determined by Sibanye-Stillwater or required by the Takeover Code, and
permitted by applicable law and regulation, the Offer will not be made, directly or indirectly, in, into
or from a Restricted Jurisdiction where to do so would violate the laws in that jurisdiction, and the
Offer will not be capable of acceptance from or within a Restricted Jurisdiction or any other
jurisdiction if to do so would constitute a violation of the laws of that jurisdiction. Accordingly,
copies of this Announcement and all documents relating to the Offer are not being, and must not
be, directly or indirectly, mailed, transmitted or otherwise forwarded, distributed or sent in, into or
from a Restricted Jurisdiction where to do so would violate the laws in that jurisdiction, and
persons receiving this Announcement and all documents relating to the Offer (including
custodians, nominees and trustees) must not mail or otherwise distribute or send them in, into or
from such jurisdictions where to do so would violate the laws in that jurisdiction.

The availability of the Offer to Lonmin Shareholders who are not resident in the United Kingdom
may be affected by the laws of the relevant jurisdictions in which they are resident. Persons who




                                                   9
are not resident in the United Kingdom should inform themselves of, and observe, any applicable
requirements.

The New Sibanye-Stillwater Shares may not be offered, sold or delivered, directly or indirectly, in,
into or from any Restricted Jurisdiction or to, or for the account or benefit of, any Restricted
Overseas Persons except pursuant to an applicable exemption from, or in a transaction not
subject to, applicable securities laws of those jurisdictions.

Notes to US holders of Lonmin Shares

The New Sibanye-Stillwater Shares, which will be issued in connection with the Offer, have not
been, and will not be, registered under the US Securities Act or under the securities law of any
state, district or other jurisdiction of the United States. Accordingly, the New Sibanye-Stillwater
Shares may not be offered, sold, resold, delivered, distributed or otherwise transferred, directly or
indirectly, in or into or from the United States absent registration under the US Securities Act or an
exemption therefrom. The New Sibanye-Stillwater Shares are expected to be issued in reliance
upon the exemption from the registration requirements of the US Securities Act provided by
Section 3(a)(10) thereof. Lonmin Shareholders (whether or not US persons) who are or will be
affiliates (within the meaning of the US Securities Act) of Sibanye-Stillwater or Lonmin prior to, or
of Sibanye-Stillwater after, the Effective Date will be subject to certain US transfer restrictions
relating to the New Sibanye-Stillwater Shares received pursuant to the Scheme. For the purposes
of qualifying for the exemption from the registration requirements of the US Securities Act afforded
by Section 3(a)(10), Lonmin will advise the Court that its sanctioning of the Scheme will be relied
upon by Sibanye-Stillwater as an approval of the Scheme following a hearing on its fairness to
Lonmin Shareholders.

The receipt of New Sibanye-Stillwater Shares pursuant to the Offer by a US Lonmin 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 Lonmin Shareholder is urged to consult his
independent professional adviser immediately regarding the tax consequences of the Offer.

It may be difficult for US Lonmin Shareholders to enforce their rights and claims arising out of the
US federal securities laws, since Sibanye-Stillwater and Lonmin are located in countries other than
the United States, and some or all of their officers and directors may be residents of countries
other than the United States. US Lonmin 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 this Announcement 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 this Announcement. Any representation to the contrary is a criminal
offence in the United States.

The Offer will be subject to the applicable requirements of the Takeover Code, the Panel, the
London Stock Exchange, the Financial Conduct Authority, the UKLA and the Johannesburg Stock
Exchange.

                   THIS ANNOUNCEMENT CONTAINS INSIDE INFORMATION



                                                                             14 December 2017

                           RECOMMENDED ALL-SHARE OFFER

                                             for

                                 Lonmin Plc (“Lonmin”)
                                           by
        Sibanye Gold Limited (trading as Sibanye-Stillwater) (“Sibanye-Stillwater”)

                   to be effected by means of a scheme of arrangement
                       under Part 26 of the UK Companies Act 2006

1   Introduction
    The Boards of Sibanye-Stillwater and Lonmin are pleased to announce that they have
    reached agreement on the terms of a recommended all-share offer pursuant to which
    Sibanye-Stillwater, and/or a wholly-owned subsidiary of Sibanye-Stillwater, will acquire the
    entire issued and to be issued ordinary share capital of Lonmin (the “Offer”). It is proposed
    that the Offer will be effected by means of a scheme of arrangement between Lonmin and
    the Lonmin Shareholders under Part 26 of the UK Companies Act.

2   The Offer
    Under the terms of the Offer, which will be subject to the Conditions and further terms set
    out below and in Appendix I to this Announcement and the full terms and conditions which
    will be set out in the Scheme Document, each Lonmin Shareholder will be entitled to
    receive:

           for each Lonmin Share                   0.967 New Sibanye-Stillwater Shares

    Based on the 30 trading day volume weighted average price of R18.67 of Sibanye-Stillwater
    Shares on the Johannesburg Stock Exchange for the period ended 13 December 2017
    (being the last Business Day prior to the date of this Announcement) and the exchange rate
    on that date being R18.056:£1, the Offer values each Lonmin Share at 100.0 pence and
    values the existing issued ordinary share capital of Lonmin at approximately £285 million
    and represents a premium of approximately:

    -       57 per cent. to the closing price per Lonmin Share of 63.8 pence on 13 December
            2017; and




                                              14
-      41 per cent. to the 30 trading day volume weighted average price per Lonmin Share
       for the period ended 13 December 2017 of 71.1 pence.

The Exchange Ratio of the Offer has been determined using the 30 trading day volume
weighted average price for Sibanye-Stillwater to smooth out the daily movements.

Based on the closing price of R16.11 of a Sibanye-Stillwater Share on the Johannesburg
Stock Exchange on 13 December 2017 and applying the same exchange rate, the Offer
values each Lonmin Share at 86.3 pence and represents a premium of approximately 35
per cent. to the closing price per Lonmin Share of 63.8 pence on 13 December 2017.

Following completion of the Acquisition, Lonmin Shareholders will hold approximately 11.3
per cent. of the Enlarged Sibanye-Stillwater Group and Sibanye-Stillwater Shareholders will
hold approximately 88.7 per cent. of the Enlarged Sibanye-Stillwater Group.

The Exchange Ratio assumes that Lonmin Shareholders will not receive any dividend after
the date of this Announcement. If any dividend or other distribution is authorised, declared,
made or paid in respect of Lonmin Shares on or after the date of this Announcement and
prior to the Effective Date, the Exchange Ratio will be adjusted downwards on an equivalent
basis to reflect the amount of any such dividend or other distribution.

It is expected that the Scheme will become effective in the second half of 2018, subject to
the satisfaction or (where applicable) waiver of the Conditions and certain further terms set
out in Appendix I to this Announcement.

Sibanye-Stillwater Shareholder approval will also be required in relation to the allotment and
issue of the New Sibanye-Stillwater Shares to Lonmin Shareholders in accordance with
clause 8.2.2 of the Sibanye-Stillwater MOI, by way of an ordinary resolution. For the
ordinary resolution to be approved, it must be supported by more than 50 per cent. of the
voting rights exercised on the ordinary resolution at the Sibanye-Stillwater Shareholder
Meeting. Sibanye-Stillwater will therefore seek the requisite approvals of the Sibanye-
Stillwater Shareholders for the allotment and issue of the New Sibanye-Stillwater Shares for
the purposes of the Offer at the Sibanye-Stillwater Shareholder Meeting which is expected
to be held at or around the same time as the Lonmin General Meeting, both of which will be
held as soon as reasonably practicable following the receipt of all of the relevant clearances
from the competition and regulatory authorities, in particular those in South Africa and the
United Kingdom (or if applicable, the European Union, in case a referral is made to the
European Commission pursuant to Article 22 of Council Regulation (EC) 139/2004) (unless
Sibanye-Stillwater and Lonmin otherwise agree).

The Scheme Document will be published in due course around the time that all relevant
clearances from the competition and regulatory authorities, in particular those in South
Africa and the United Kingdom (or, if applicable, the European Union, in case a referral is
made to the European Commission pursuant to Article 22 of Council Regulation (EC)
139/2004), have been received. The Scheme Document will be made available in due
course         by        Sibanye-Stillwater         on        its       website          at
www.sibanyestillwater.com/investors/transactions/lonmin and by Lonmin on its website at
www.lonmin.com/investors/sibanye-stillwater-offer.

The Sibanye-Stillwater Circular, containing (amongst other things) the notice of the Sibanye-
Stillwater Shareholder Meeting (including the resolution to be adopted by the Sibanye-
Stillwater Shareholders), together with the Forms of Proxy, will be posted to Sibanye-
Stillwater Shareholders at or around the same time as the Scheme Document is published.




                                          15
          The Sibanye-Stillwater Circular will also be made available in due course by Sibanye-
          Stillwater on its website at www.sibanyestillwater.com/investors/transactions/lonmin and by
          Lonmin on its website at www.lonmin.com/investors/sibanye-stillwater-offer.

3         Background to and reasons for the Offer
          Sibanye-Stillwater believes that the Acquisition is compelling for Sibanye-Stillwater
          Shareholders and is a logical step in executing its PGM strategy. By combining Sibanye-
          Stillwater’s existing, and contiguous, South African PGM assets with Lonmin's operations,
          including Lonmin's processing facilities, Sibanye-Stillwater will be able to unlock operational
          synergies and become a fully integrated PGM producer in South Africa, thereby creating
          value for all stakeholders.

          In particular, Sibanye-Stillwater has identified the following principal benefits to the Sibanye-
          Stillwater Group from the Acquisition:

          Consistent with Sibanye-Stillwater’s strategy

          The Acquisition is consistent with Sibanye-Stillwater’s South African PGM strategy following
          the acquisitions of Aquarius Platinum and the Rustenburg Operations from Anglo American
          Platinum. This strategy is underpinned by enhancing operational profitability through the
          realisation of operational and overhead synergies, thereby ensuring the sustainability of
          operations and creating value for all stakeholders. The contiguous nature of the Lonmin and
          Rustenburg Operations enhances the scale of Sibanye-Stillwater’s operations, providing
          further opportunities to effectively allocate capital, improve asset performance of the asset
          base and facilitate operational flexibility. Optimising the utilisation on the combined assets
          will create long-term value for Sibanye-Stillwater Shareholders and benefit all stakeholders
          in the region.
                                                                                                                      1
          Sibanye-Stillwater is a global PGM producer with 4E production of approximately 1.70Moz.
          The Acquisition will materially expand Sibanye-Stillwater’s PGM footprint, adding
          approximately 31.7Moz in proven and probable reserves (as per Lonmin’s declared mineral
          reserves at 30 September 2016) and is expected to give the Enlarged Sibanye-Stillwater
                                                    2
          Group pro forma 4E production of 2.80Moz.

          Access to own processing facilities in South Africa

          Lonmin is one of only three fully integrated South African PGM producers with full ownership
          of a metallurgical processing complex, including smelting, base and precious metals refining
          facilities. The addition of these mine-to-market capabilities in South Africa (at an acquisition
          cost of significantly less than replacement cost) represents a logical step for Sibanye-
          Stillwater's South African PGM business, creating a fully integrated precious metals
          producer. Lonmin's processing facilities will allow Sibanye-Stillwater in due course to smelt
          and refine ore from its existing Rustenburg Operations, enhancing and improving the
          economics of those operations, while simultaneously ensuring a sustainable source of
          material for these facilities, therefore maximising return on assets.

          Realisation of significant synergies between Sibanye-Stillwater and Lonmin's
          contiguous assets

The Board of Sibanye-Stillwater believes that, as a direct result of the Acquisition, there are
a number of areas where the Enlarged Sibanye-Stillwater Group could benefit from
attractive synergies, creating additional value for Sibanye-Stillwater Shareholders. Sibanye-
Stillwater has demonstrated its ability to extract synergies from the recently acquired
Aquarius Platinum and Rustenburg Operations. Sibanye-Stillwater has already realised
R550 million per annum in annualised operational synergies as at 30 June 2017 from the
Aquarius Platinum and Rustenburg Operations acquisitions and is expected to realise
approximately R1,000 million of annualised synergies by 2018.

Sibanye-Stillwater has identified expected total pre-tax run-rate synergies of approximately
R1,500 million by 2021, averaging approximately R1,280 million per annum for the period
2021 to 2032, as a result of the Acquisition, including:

-      in relation to overhead services, a total of approximately R730 million per annum by
       2021, with respect to:

       -         shared services between members of the Enlarged Sibanye-Stillwater
                 Group;

       -         overhead costs in respect of management and marketing;

       -         shared mining services; and

       -         shared corporate and regulatory costs;

-      in relation to processing synergies, a total of approximately R780 million per annum
       by 2021, averaging approximately R550 million per annum for the period 2021 to
       2032, primarily by utilising spare capacity within Lonmin’s smelting and refining
       infrastructure to process concentrate produced by the Rustenburg Operations.

These savings from overhead synergies and reduced processing costs are separate from
those matters contained in Lonmin’s Operational Review (as described in paragraph 4 of
this Announcement) and those matters addressed in Lonmin’s evolving business plan (as
described in paragraph 8 of this Announcement).

Sibanye-Stillwater estimates that the implementation of the overhead synergies would give
rise to expected one-off costs of approximately R80 million and a headcount reduction of
approximately 700. In addition, implementation of the processing synergies would give rise
to expected one-off costs of approximately R1,000 million, such one-off costs to be incurred
primarily in relation to the construction of an additional smelting furnace and Sibanye-
Stillwater will continue to explore other ways to mitigate such one-off costs.

Aside from such one-off costs referred to above, Sibanye-Stillwater does not expect any
material dis-synergies to arise in connection with the Acquisition.

Sibanye-Stillwater has also identified a number of further initiatives and benefits which are
not included in the quantified estimate of achievable synergies, including:

-      the ability to mine through existing mine boundaries between Sibanye-Stillwater and
       Lonmin operations, allowing for the optimisation of ore extraction in these areas;

-      optimal use of surface infrastructure, including concentrators, tailings deposition
       facilities and training and engineering infrastructure;

-      optimising the mining mix of Merensky and UG2 of the Enlarged Sibanye-Stillwater
       Group;



                                          17
-      new growth capital and project prioritisation; and

-      capital reorganisation in line with Sibanye-Stillwater’s new consolidated regional
       plan.

The ability to realise synergies within the combined portfolio underpins the value enhancing
nature of the Acquisition for Sibanye-Stillwater Shareholders. Sibanye-Stillwater anticipates
that the Acquisition will be net asset value accretive on completion of the Acquisition and
earnings and cash flow accretive in respect of Sibanye-Stillwater Shares from 2021, once
the related one-off costs referred to in this paragraph 3 have been incurred and the
identified synergies begin to be realised in full by the Enlarged Sibanye-Stillwater Group.
The Acquisition is expected to enhance the Enlarged Sibanye-Stillwater Group’s ability to
withstand the current low PGM price environment and short-term industry volatility, while
also funding the long-term growth potential of the existing resources with expected
improving market and economic conditions. The Enlarged Sibanye-Stillwater Group will also
benefit from reduced operational risk, as greater asset diversity reduces the impact of
production and disruption risk.

These statements of estimated cost savings and synergies relate to future actions and
circumstances which, by their nature, involve risks, uncertainties and contingencies. As a
result, the cost savings and synergies referred to may not be achieved, may be achieved
later or sooner than estimated, or those achieved could be materially different from those
estimated. For the purposes of Rule 28 of the Takeover Code, the statements of estimated
cost savings and synergies contained in this Announcement are solely the responsibility of
Sibanye-Stillwater and the Sibanye-Stillwater Directors, and are expected to arise as a
direct result of the Acquisition and could not be achieved independently of the Acquisition.
Neither this statement nor any other statement in this Announcement are intended to be a
profit forecast and should not be interpreted to mean that earnings per Sibanye-Stillwater
Share for the current or future financial years would necessarily match or exceed the
historical published earnings per Sibanye-Stillwater Share.

Part A of Appendix IV to this Announcement includes a copy of these statements of
anticipated cost savings and synergies arising out of the Acquisition and provides underlying
information and bases of belief. Part B and Part C of Appendix IV to this Announcement also
include reports from Sibanye-Stillwater’s reporting accountant, BDO, and Sibanye-
Stillwater’s Financial Advisers, UBS and HSBC, in connection with the anticipated quantified
financial benefits statement, as required pursuant to Rule 28.1(a) of the Takeover Code.
Each of BDO, UBS and HSBC has given and not withdrawn its consent to the publication of
its report in this Announcement in the form and context in which it is included.

Potential upside from developmental projects

The Acquisition will materially expand Sibanye-Stillwater’s PGM footprint, adding 180.6Moz
in measured, indicated and inferred resources. This significant resource base includes well
advanced projects, providing significant upside optionality to deliver future stakeholder value
in an appropriate economic environment. These attractive brownfield projects include K4,
Limpopo and Pandora, as well as a greenfields project pipeline, including Akanani.

Sibanye-Stillwater’s approach to Lonmin’s operations

By applying Sibanye-Stillwater’s operating model, Sibanye-Stillwater has the ability to create
value for both Sibanye-Stillwater Shareholders and Lonmin Shareholders. As part of a larger
entity, Lonmin’s operations will be less constrained by significant fixed overhead costs which




                                          18
    have in the past driven the need to fill processing capacity. This has resulted in the need to
    plan for sub-optimal capital deployment and the potential for cross subsidisation of
    unprofitable mining areas. The Acquisition will enhance Sibanye-Stillwater's flexibility to
    apply a more prudent approach to capital investment with respect to Lonmin's assets, more
    closely aligned to market demands and commodity prices, enhancing the longer term
    sustainability of the operations for the benefit of all stakeholders.

    To this end, Sibanye-Stillwater has developed a conservative Lonmin operating plan, which
    is not contingent on the development of new major capital projects and therefore limits
    downside risk while providing full upside optionality in appropriate economic and market
    circumstances.

4   Background to and reasons for the Lonmin Directors’ recommendation
    Lonmin has experienced financial constraints for a number of years caused by a range of
    external factors such as a persistently low PGM pricing environment and the inflationary
    cost pressures of operating in the South African PGM mining industry, which have been
    further exacerbated by internal factors including operational, social and labour issues.

    On 21 October 2015, Lonmin announced a rights issue to raise approximately US$407
    million in gross proceeds and executed an agreement on an amended facilities agreement
    with its lenders, together with a new business plan, which were intended to put the Lonmin
    Group in a stronger financial position and enable it to deal with a low PGM pricing
    environment. The 2015 rights issue was the third rights issue undertaken by the Lonmin
    Group since 2009, with approximately US$1.6 billion of aggregate gross proceeds raised
    from the three rights issues.

    Since 2015, Lonmin’s strategy has been to focus on factors within its control in order to
    maintain broadly flat unit costs and cash generation, with a particular focus on reducing
    fixed costs, removing high cost production, reducing capital expenditure and continuing to
    improve relationships with key stakeholders. However, the adverse PGM pricing
    environment has continued to prevail and the inflationary cost pressures have remained,
    exacerbated by a strong R:US$ exchange rate.

    On 15 May 2017, as part of its interim results for the period ended 31 March 2017, Lonmin
    announced that its auditors had identified an issue in relation to the Lonmin Group’s ability
    to continue as a going concern due to a material uncertainty in relation to its existing debt
    facilities. This was due to a non-cash impairment to the carrying value of the Lonmin
    Group’s assets, and the possibility that a further impairment could result in Lonmin
    breaching its consolidated tangible net worth (“TNW”) financial covenants and thereby
    triggering the potential withdrawal of the Lonmin Group's debt facilities. The TNW financial
    covenants are reviewed monthly with significant movements in TNW likely to result from
    impairment reviews which take place every six months on the reporting dates. Impairments
    are driven by variables including macroeconomic factors outside Lonmin’s direct control,
    such as the period-end R:US$ exchange rate (the volatility of which also creates inherent
    uncertainty around the impairment testing) and the PGM price outlook.

    On 7 August 2017, Lonmin announced the initial conclusions of an ongoing operational
    review (the “Operational Review”) with the primary objective of preserving value for
    shareholders and safeguarding the long-term interests of employees and all key
    stakeholders. The immediate results of the Operational Review included initiatives to
    generate cash and reduce fixed costs with the objective of supporting a sustainable




                                              19
business. This included exploring the potential disposal of selected assets and the reduction
in fixed overhead costs by R500 million by the end of the financial year ending 30
September 2018.

On 6 October 2017, Lonmin announced that it had requested and obtained a pre-emptive
waiver for its TNW financial covenants from its lenders until 30 March 2018 to provide
sufficient time to reach a conclusion on its Operational Review.

On 3 November 2017, Lonmin announced that the publication of its audited financial
statements for the financial year ended 30 September 2017 would be delayed pending
potentially significant outcomes of the Operational Review. Lonmin noted that such
outcomes (together with ongoing discussions with its existing and prospective lenders)
could have a material bearing on the Lonmin Directors' assessment of the basis of
preparation of the audited financial statements of Lonmin for the financial year ended 30
September 2017 as a going concern.

In recent months, and in parallel with its work on the Operational Review, the Board of
Lonmin has also been in discussions with Sibanye-Stillwater about a possible offer for
Lonmin. The Board of Lonmin has concluded that the acquisition of Lonmin by Sibanye-
Stillwater represents a comprehensive and more certain solution to the challenges facing
Lonmin than Lonmin could achieve by any alternative route. The Board of Lonmin believes
that a combination of Sibanye-Stillwater and Lonmin creates a larger and more resilient
company, with greater geographical and commodity diversification, that is better able to
withstand short-term commodity price and foreign exchange volatility. The Offer also allows
Lonmin Shareholders to participate in:

-      the growth and value creation opportunities of the Enlarged Sibanye-Stillwater
       Group;

-      the benefits from the realisation of synergies from the combination of Sibanye-
       Stillwater and Lonmin; and

-      any long-term recovery in the fundamentals of the PGM sector.

In addition, the Board of Lonmin believes that the Offer delivers the best value for Lonmin
Shareholders. Based on the 30 trading day volume weighted average price of R18.67 of
Sibanye-Stillwater Shares on the Johannesburg Stock Exchange for the period ended 13
December 2017 (being the last Business Day prior to the date of this Announcement) and
the exchange rate on that date being R18.056:£1, the Offer values each Lonmin Share at
100.0 pence and represents a premium of approximately:

-      57 per cent. to the closing price per Lonmin Share of 63.8 pence on 13 December
       2017; and

-      41 per cent. to the 30 trading day volume weighted average price per Lonmin Share
       for the period ended 13 December 2017 of 71.1 pence.

Based on the closing price of R16.11 of a Sibanye-Stillwater Share on the Johannesburg
Stock Exchange on 13 December 2017 and applying the same exchange rate, the Offer
values each Lonmin Share at 86.3 pence and represents a premium of approximately 35
per cent. to the closing price per Lonmin Share of 63.8 pence on 13 December 2017.

The Board of Lonmin believes that there is a significant risk of Lonmin breaching its TNW
financial covenants on 31 March 2018. In this event, in the absence of the Offer or an
alternative material transaction resulting from the Operational Review, Lonmin may be



                                          20
    unable to obtain a waiver from its lenders and/or additional liquidity. In these circumstances,
    Lonmin is unlikely to be able to repay or refinance its existing facilities while meeting its
    working capital requirements and, as a result, Lonmin may be unable to continue as a going
    concern at that time. Prior to this Announcement, Lonmin has had encouraging discussions
    with representatives of its South African Rand lenders regarding their willingness to grant
    further waivers. Immediately following this Announcement, Lonmin intends to engage with
    all of its lenders in order to obtain the further waiver of such covenants until completion of
    the Acquisition.

    Prior to completion of the Acquisition, Lonmin intends to work with Sibanye-Stillwater (to the
    extent legally permissible) to ensure that the business continues to address the financial
    and operational challenges it faces in the best long-term interests of Lonmin and Lonmin
    Shareholders.

5   Lonmin Directors’ recommendations and irrevocable undertakings
    The Lonmin Directors, who have been so advised by Gleacher Shacklock, J.P. Morgan
    Cazenove and Moshe Capital as to the financial terms of the Offer, consider the terms of the
    Offer to be fair and reasonable. In providing advice to the Lonmin Directors, Gleacher
    Shacklock, J.P. Morgan Cazenove and Moshe Capital have taken into account the
    commercial assessments of the Lonmin Directors.

    The Lonmin Directors consider the terms of the Offer to be in the best interests of Lonmin
    Shareholders as a whole and intend unanimously to recommend that Lonmin Shareholders
    vote in favour of the Scheme at the Court Meeting and the resolutions to be proposed at the
    Lonmin General Meeting which is to be convened to approve the Offer, as the Lonmin
    Directors have irrevocably undertaken to Sibanye-Stillwater to do in respect of their own
    beneficial shareholdings in Lonmin which amount in aggregate to 75,498 Lonmin Shares,
    representing approximately 0.026698 per cent. of the existing issued ordinary share capital
    of Lonmin in issue on 13 December 2017 (being the last Business Day prior to the date of
    this Announcement).

    In the event that the Acquisition is implemented by way of a Takeover Offer, the Lonmin
    Directors intend unanimously to recommend that Lonmin Shareholders accept or procure
    acceptance of such Takeover Offer. It is the Lonmin Directors’ intention, immediately
    following the announcement by Lonmin of its results for the financial year ended 30
    September 2017, which will end the closed period to which Lonmin is subject under Article
    19(11) of the Market Abuse Regulation as at the date of this Announcement, to undertake
    irrevocably to accept or procure the acceptance of such Takeover Offer in respect of their
    own holdings of Lonmin Shares.

    Further details of these irrevocable undertakings (including the circumstances in which they
    will fall away) are set out in Appendix III to this Announcement.

    date of this Announcement), the Lonmin Group had 24,617 full-time employees and utilised
    a further 8,063 contractors.

8   Directors, management, employees and locations
    Lonmin

    As noted in paragraph 4 of this Announcement, and which Lonmin believes it has in
    common with several other South African platinum mining companies, Lonmin’s business
    has experienced ongoing financial constraints for a number of years caused by a range of
    external factors such as a persistently low PGM pricing environment and the inflationary
    cost pressures of operating in the South African PGM industry, which have been further
    exacerbated by internal factors including operational, social and labour issues.

    The Board of Lonmin believes that if these low prices persist, in addition to the drop-off in
    production profile of the ageing Generation One shafts, and regardless of whether or not the
    Acquisition is implemented, potentially in excess of 12,000 jobs in Lonmin would be at risk
    over the next three years.




                                             23
Lonmin continuously engages with its workforce through future forums in order to manage
and mitigate the risk of job losses and of placing mines on care and maintenance. Through
these future forums Lonmin also communicates the economic and operational realities of its
business to its workforce and discusses the efficiencies it seeks in order to mitigate job
losses.

In connection with the outcomes of the Operational Review, Lonmin expects that it will be
necessary to place its ageing Generation One shafts, which are at the end of their reserve
lives, on care and maintenance. It is anticipated that these steps would be accompanied by
associated overhead savings to contain operational costs.

Lonmin’s evolving business plan will possibly result in headcount reductions associated with
placing shafts on care and maintenance and this process has commenced in accordance
with South African laws and in consultation with employee representative bodies. The
placing of the Generation One shafts on care and maintenance, together with the
operational efficiency improvement program which commenced in 2015, could impact
approximately 3,700 employees (including approximately 800 contractors) in 2018. Placing
further Generation One shafts on care and maintenance in 2019 could impact approximately
a further 4,800 operational employees (including approximately 2,000 contractors). This
potential reduction in the operational base would necessitate the downscaling of overhead
and support services, placing approximately a further 500 employees possibly at risk of job
losses. While the impact on possible job losses in the first two years is primarily driven by
placing high-cost and depleting Generation One shafts on care and maintenance,
forecasting the potential impact on employment beyond a two year period is dependent on
future commodity prices and business liquidity. However, should commodity prices remain in
their current depressed state for a further three years an additional estimated 3,600 jobs
could be at risk in 2020.

Enlarged Sibanye-Stillwater Group

Sibanye-Stillwater has reviewed Lonmin’s evolving business plan and concurs that the
restructuring is necessary as mining operations reach the end of their reserve lives.

The Boards of Sibanye-Stillwater and Lonmin recognise that the integration of Lonmin into
the Enlarged Sibanye-Stillwater Group will create the opportunity to achieve the expected
synergistic benefits of the Acquisition, enhancing the potential longer term sustainability of
Lonmin’s remaining (excluding the Generation One shafts) operations. In addition to
benefitting ongoing operating costs, this integration will also result in creating flexibility
associated with the timing of the significant capital investment that would be required to
develop the next generation operating shafts to sustain mining output from Lonmin’s
operations.

The synergy work carried out to date has confirmed the potential to generate cost-savings
for the Enlarged Sibanye-Stillwater Group. Although Sibanye-Stillwater continues to develop
an initial business plan for the Enlarged Sibanye-Stillwater Group, it estimates that
headcount reductions of approximately 890 (including approximately 320 contactors)
employees not envisaged in the Lonmin evolving business plan for 2018 to 2020 could be
required. These reductions include approximately 700 employees from the Enlarged
Sibanye-Stillwater Group in executive functions, management and centralised roles in areas
of overlapping corporate and support functions (including in respect of shared services,
management, marketing, mining services, corporate and regulatory costs).




                                          24
     Finalisation of the business plan for the Enlarged Sibanye-Stillwater Group and integration
     planning will follow a transparent and detailed review of the Lonmin Group’s business and
     will be conducted in line with the regulatory processes in South Africa, which include
     engagement and consultation with employees and their representative bodies. The
     implementation of any such restructuring would seek to identify and retain the best talent
     from both Sibanye-Stillwater and Lonmin.

     The non-executive Lonmin Directors will resign from the Board of Lonmin upon completion
     of the Acquisition.

     Lonmin’s operational headquarters

     Sibanye-Stillwater expects to retain Lonmin’s operational headquarters in Marikana, but
     recognises that opportunities exist to rationalise premises and final locations of the Enlarged
     Sibanye-Stillwater Group. A thorough assessment will be undertaken in this regard following
     completion of the Acquisition. It is expected that the Enlarged Sibanye-Stillwater Group’s
     global corporate office will remain in Johannesburg and that Lonmin’s office in London will
     close.

     The contractual and statutory employment rights, including in relation to pensions, of all
     Sibanye-Stillwater and Lonmin employees will be fully observed in accordance with
     applicable law following completion of the Acquisition.

9    Lonmin Share Plans
     Participants in Lonmin Share Plans will be contacted regarding the effect of the Offer on
     their rights under the Lonmin Share Plans and appropriate proposals will be made to such
     participants in due course. Further details of the terms of such proposals will be included in
     the Scheme Document and in separate letters to be sent to participants in the Lonmin Share
     Plans.

10   Lonmin’s credit facilities
     The Lonmin Group has in place two credit facilities with a number of banks. The aggregate
     amount outstanding under these credit facilities is approximately US$150 million. Lonmin
     will fully prepay and cancel all of such credit facilities at, or immediately prior to, completion
     of the Acquisition.

     In addition, as at 12 December 2017 (being the last practicable date prior to the date of this
     Announcement), the Lonmin Group maintains a net cash position, such that the total value
     of the cash (including cash equivalents and other liquid assets) available to the Lonmin
     Group exceeds the total value of the debts and liabilities of the Lonmin Group. Lonmin
     intends to notify Sibanye-Stillwater in writing if, at any time prior to the Longstop Date, the
     Lonmin Group moves, or anticipates that it will move, to a net debt position such that the
     total value of the Lonmin Group’s debts and liabilities exceeds the total value of the cash
     (including cash equivalents and other liquid assets) available to the Lonmin Group.

11   Structure of and Conditions to the Offer
     It is intended that the Offer will be effected by means of a Court-approved scheme of
     arrangement between Lonmin and Lonmin Shareholders under Part 26 of the UK
     Companies Act.




                                                 25
The purpose of the Scheme is to provide for Sibanye-Stillwater to become the holder of the
entire issued and to be issued ordinary share capital of Lonmin. This is to be achieved by
the transfer of the Lonmin Shares to Sibanye-Stillwater, in consideration for which the
Lonmin Shareholders will receive the New Sibanye-Stillwater Shares on the basis set out in
paragraph 2 of this Announcement.

The Offer is subject to the Conditions and further terms set out below and in Appendix I to
this Announcement and to be set out in the Scheme Document and the Forms of Proxy and
will only become effective if, among other things, the following events occur on or before 28
February 2019 or such later date as may be agreed in writing by Sibanye-Stillwater and
Lonmin (with the Panel’s consent and as the Court may approve (if such approval(s) are
required)):

(i)       the approval of the Scheme by a majority in number of the Lonmin Shareholders
          who are present and vote (and are entitled to vote), whether in person or by proxy,
          at the Court Meeting and who represent 75 per cent. in value of the Lonmin Shares
          voted by those Lonmin Shareholders;

(ii)      the resolutions required to implement the Scheme being duly passed by Lonmin
          Shareholders representing the requisite majority or majorities of votes cast at the
          Lonmin General Meeting (or at any adjournment of that meeting);

(iii)     the approval of the Scheme by the Court (with or without modification, but subject
          to any modification being on terms acceptable to Lonmin and Sibanye-Stillwater);

(iv)      the delivery of a copy of the Court Order to the Registrar of Companies;

(v)       certain competition and regulatory approvals (including in South Africa and the
          United Kingdom (or the European Union, in case a referral is made to the
          European Commission pursuant to Article 22 of the Council Regulation (EC)
          139/2004) being obtained;

(vi)      the Licences Condition, as described below, not being invoked;

(vii)     the resolution of Sibanye-Stillwater Shareholders to allot and issue the New
          Sibanye-Stillwater Shares in connection with the Offer being duly passed by
          Sibanye-Stillwater Shareholders representing more than 50 per cent. of the voting
          rights exercised on the ordinary resolution at the Sibanye-Stillwater Shareholder
          Meeting (or at any adjournment of that meeting); and

(viii)    the New Sibanye-Stillwater Shares being admitted to trading on the Johannesburg
          Stock Exchange.

The Offer will lapse if:

-        the Court Meeting and the Lonmin General Meeting are not held on or before the
            nd
         22 day after or the expected date of the Court Meeting and the Lonmin General
         Meeting to be set out in the Scheme Document in due course (or such later date as
         may be agreed between Sibanye-Stillwater and Lonmin);
                                                                                     nd
-        the Court hearing to approve the Scheme is not held on or before the 22 day after
         the expected date of the Court sanction hearing to be set out in the Scheme
         Document in due course (or such later date as may be agreed between Sibanye-
         Stillwater and Lonmin); or

-        the Scheme does not become effective by the Longstop Date,



                                          26
     provided, however, that the deadlines for the timing of the Court Meeting, the Lonmin
     General Meeting and the Court hearing to approve the Scheme as set out above may be
     waived by Sibanye-Stillwater, and the deadline for the Scheme to become effective may be
     extended by agreement between Lonmin and Sibanye-Stillwater.

     Sibanye-Stillwater and Lonmin have agreed in principle that if the Acquisition does not
     complete as a result of Sibanye-Stillwater Shareholders not passing the resolution to be
     proposed in connection with the Acquisition at the Sibanye-Stillwater Shareholder Meeting,
     Sibanye-Stillwater and Lonmin will, at Lonmin’s option, enter into good faith discussions to
     enter into an asset transaction as envisaged as part of the Operational Review pursuant to
     which Sibanye-Stillwater would acquire Lonmin assets of sufficient quantum to ensure
     Lonmin could continue to operate as a going concern in the medium term. Such an
     arrangement would be subject to all necessary approvals including by Lonmin
     Shareholders.

     The Licences Condition is specifically drawn to the attention of Lonmin Shareholders. It is a
     Condition of the Offer that, following the date of this Announcement, there is no cancellation
     of any prospecting right or mining right held by a member of the Wider Lonmin Group
     pursuant to Section 47 of the MPRDA where such cancellation is material in the context of
     the Wider Lonmin Group taken as a whole, and if such a cancellation has occurred it has
     not been: (i) withdrawn, lifted or revoked in writing by the Minister; or (ii) set aside, nullified
     or otherwise suspended by the order of a court of competent jurisdiction, within 15 Business
     Days of such cancellation (or, if earlier, by the date scheduled for the Court hearing to
     approve the Scheme).

     Subject to satisfaction (or waiver, where applicable) of the Conditions, the Scheme is
     expected to become effective in the second half of 2018.

     Upon the Scheme becoming effective, it will be binding on all Lonmin Shareholders,
     irrespective of whether or not they attended or voted at the Court Meeting or the Lonmin
     General Meeting.

     Further details of the Scheme, including an indicative timetable for its implementation, will
     be set out in the Scheme Document.

12   Lonmin dividends
     The Exchange Ratio assumes that Lonmin Shareholders will not receive any dividend after
     the date of this Announcement. If any dividend or other distribution is authorised, declared,
     made or paid in respect of Lonmin Shares on or after the date of this Announcement, the
     Exchange Ratio will be adjusted downwards on an equivalent basis to reflect the amount of
     any such dividend or other distribution.

13   Fractional entitlements
     Fractions of New Sibanye-Stillwater Shares will not be issued pursuant to the Offer.
     Entitlements to New Sibanye-Stillwater Shares pursuant to the Offer will be rounded down
     to the nearest whole number of New Sibanye-Stillwater Shares.




                                                 27
14   Admission of New Sibanye-Stillwater Shares and de-listing of Lonmin Shares
     The New Sibanye-Stillwater Shares will, when issued, be ordinary shares in the authorised
     capital of Sibanye-Stillwater each with no par value, will be fully paid and rank pari passu in
     all respects with the Sibanye-Stillwater Shares in issue at the date of this Announcement.

     It is expected that Admission of the New Sibanye-Stillwater Shares to the Main Board of the
     Johannesburg Stock Exchange will become effective and dealings for normal settlement in
     the New Sibanye-Stillwater Shares will commence at or shortly after 9.00 am
     (Johannesburg time) on the Admission Date.

     Prior to the Scheme becoming effective on the Effective Date, Lonmin will make an
     application for the cancellation of listing of the Lonmin Shares on the Official List and trading
     on the Main Market of the London Stock Exchange and for a removal from the Main Board
     of the Johannesburg Stock Exchange, which is expected to take effect with regard to the
     Official List and the Main Market of the London Stock Exchange from the Admission Date
     and with regard to the Main Board of the Johannesburg Stock Exchange from the Business
     Day after the Admission Date.

     The last day of dealings in Lonmin Shares on the Main Market of the London Stock
     Exchange is expected to be the Business Day immediately prior to the Effective Date and
     no transfers will be registered after 6.00 pm (London time) on that date. The last day of
     dealings in Lonmin Shares on the board of the Johannesburg Stock Exchange is expected
     to be the fourth Business Day prior to the Admission Date and no transfers shall be
     registered after 5.00 pm (Johannesburg time) on that date.

     From the first Business Day following the Effective Date, share certificates in respect of the
     Lonmin Shares will cease to be held within the CREST and STRATE systems and will be
     cancelled.

     It is also proposed that, following the Effective Date and after the Lonmin Shares are de-
     listed, Lonmin will be re-registered as a private limited company.

15   Share dealing facility
     Subject to clarifying any legal or regulatory requirements or restrictions and subject to Panel
     consent, Sibanye-Stillwater intends to offer a dealing facility to certain retail Lonmin
     Shareholders under which the New Sibanye-Stillwater Shares to which such Lonmin
     Shareholders become entitled may be sold for their benefit. Details of any such dealing
     facility will be included in the Scheme Document.

16   Lonmin American Depositary Shares
     Lonmin ADS holders will not be entitled to vote directly on the Scheme and the Offer.
     However, Lonmin ADS holders have the right to instruct the Lonmin Depositary how to vote
     the Lonmin Shares in respect of the Lonmin Shares underlying the Lonmin ADSs, subject to
     and in accordance with the terms of the Deposit Agreement. Lonmin ADS holders should
     take particular notice of the deadline for providing voting instructions, which may be earlier
     than that applicable to holders of Lonmin Shares.

     Lonmin ADS holders that wish to vote directly on the Scheme and the Offer must surrender
     their Lonmin ADSs to the Lonmin Depositary, pay the Lonmin Depositary’s fees and charges
     in accordance with the Deposit Agreement and become holders of Lonmin Shares prior to
     the Scheme Voting Record Time, and in each case subject to and in accordance with the



                                                28
     terms of the Deposit Agreement. Lonmin ADS holders that wish to vote directly on the
     Scheme should take care to surrender their Lonmin ADSs in time to permit processing to be
     completed by the Lonmin Depositary and its English custodian prior to the Scheme Voting
     Record Time. If you hold Lonmin ADSs through a broker or other securities intermediary,
     you should contact the intermediary to determine the date by which you must instruct that
     intermediary to act in order that the necessary processing can be completed in time.

17   Offer-related arrangements
     Confidentiality Agreement

     Sibanye-Stillwater and Lonmin entered into a confidentiality and standstill agreement on 18
     October 2017 (the “Confidentiality Agreement”) pursuant to which each of Sibanye-
     Stillwater and Lonmin has undertaken to keep confidential information relating to the other
     party, not to disclose it to third parties (other than to permitted disclosees) unless required
     by law or regulation and only use it in connection with the Acquisition. These confidentiality
     obligations will remain in force until completion of the Acquisition or, in the event of
     termination of the Acquisition, for a period of two years from the date of the Confidentiality
     Agreement. Sibanye-Stillwater also agreed to certain standstill undertakings, all of which
     ceased to apply upon the release of this Announcement.

     The Confidentiality Agreement also contains undertakings from both Lonmin and Sibanye-
     Stillwater that, for a period of 18 months from the date of the Confidentiality Agreement,
     neither Sibanye-Stillwater nor Lonmin will, directly or indirectly, solicit or entice away certain
     persons employed or engaged by the other party or any of its affiliates with a view to
     inducing those employees to leave such employment or engagement, nor, directly or
     indirectly solicit, entice away, canvass or approach certain suppliers or customers of the
     other party or any of its affiliates for the purpose of offering or receiving goods or services of
     the same or similar type from or to such person.

     Co-operation Agreement

     Sibanye-Stillwater and Lonmin have entered into the Co-operation Agreement dated 14
     December 2017, pursuant to which, among other things, Sibanye-Stillwater has agreed to
     lead in developing, preparing and submitting all filings, notifications or submissions in
     relation to all clearances and regulatory conditions with respect to the Acquisition, except to
     the extent that: (i) Lonmin is required to make its own filings, notifications or submissions (in
     which case Lonmin will submit such filings, notifications or submissions); or (ii) Sibanye-
     Stillwater and Lonmin are required to make joint filings, notifications or submissions (in
     which case Sibanye-Stillwater and Lonmin will jointly submit such filings, notifications or
     submissions). Sibanye-Stillwater and Lonmin have also agreed to provide such information
     and assistance as the other party may reasonably request for the purpose of obtaining all
     regulatory clearances.

     The Co-operation Agreement also records Sibanye-Stillwater and Lonmin's intention to
     implement the Acquisition by way of the Scheme, subject to Sibanye-Stillwater having the
     right to implement the Acquisition by way of a Takeover Offer in certain circumstances. The
     Co-operation Agreement also provides that Sibanye-Stillwater will consult Lonmin in relation
     to the preparation of the Sibanye-Stillwater Circular. Sibanye-Stillwater has also agreed to
     provide promptly to Lonmin all such information relating to Sibanye-Stillwater and
     assistance as Lonmin may reasonably request for the purpose of preparing the Scheme
     Document (and/or other Lonmin shareholder documentation).




                                                 29
The Co-operation Agreement also includes undertakings by Sibanye-Stillwater to: (i)
convene the Sibanye-Stillwater Shareholder Meeting, which is expected to be held at or
around the same time as the Lonmin General Meeting, as soon as reasonably practicable
following the receipt of all the relevant clearances from the competition and regulatory
authorities, in particular those in South Africa and the United Kingdom (or, if applicable, the
European Union (in case a referral is made to the European Commission pursuant to Article
22 of Council Regulation (EC) 139/2004)) (unless Sibanye-Stillwater and Lonmin otherwise
agree); and (ii) recommend that Sibanye-Stillwater Shareholders vote in favour of the
relevant resolution at the Sibanye-Stillwater Shareholder Meeting.

Lonmin and Sibanye-Stillwater have agreed that the Co-operation Agreement will terminate
in the following circumstances:

(i)     the Scheme is withdrawn or lapses prior to the Longstop Date, other than where
        such lapse or withdrawal: (a) is a result of Sibanye-Stillwater exercising its right to
        implement the Acquisition by way of a Takeover Offer; or (b) either is not confirmed
        by Sibanye-Stillwater or is followed within five Business Days by an announcement
        under Rule 2.7 of the Takeover Code made by Sibanye-Stillwater (or a person acting
        in concert with it) to implement the Acquisition by way of different offer or scheme or
        arrangement on substantially the same or improved terms);

(ii)    the Lonmin Directors fail to recommend that Lonmin Shareholders vote in favour of
        the Scheme in the Scheme Document or they withdraw, qualify or modify the
        recommendation in an adverse manner or announce an intention to do so prior to
        the Court Meeting and the Lonmin General Meeting and Sibanye-Stillwater elects to
        terminate the Co-operation Agreement;

(iii)   if Sibanye-Stillwater elects to exercise its right to implement the Acquisition by way
        of a Takeover Offer, the Lonmin Directors withdraw, qualify or modify their
        recommendation of the Takeover Offer in an adverse manner or announce an
        intention to do so and Sibanye-Stillwater elects to terminate the Co-operation
        Agreement;

(iv)    the Scheme does not become effective before the Longstop Date, or if Sibanye-
        Stillwater elects to exercise its right to implement the Acquisition by way of a
        Takeover Offer and the Takeover Offer does not become wholly unconditional before
        the Longstop Date; or

(v)     Sibanye-Stillwater and Lonmin agree in writing to such termination.

The Co-operation Agreement also contains provisions that will apply in respect of Lonmin
Share Plans, including that Lonmin has agreed that it will not process or issue any Lonmin
Shares to satisfy the exercise of any options granted under the Lonmin Share Plans
between the Scheme Voting Record Time and the Effective Date.

Regulatory Clean Team Protocol

Sibanye-Stillwater and Lonmin have put in place a Regulatory Clean Team Protocol which
sets out how confidential information that is competitively sensitive can be disclosed, used,
or shared between Sibanye-Stillwater’s external legal counsel and/or economists and
Lonmin’s external legal counsel and/or economists for the purposes of obtaining the consent
of competition authorities and/or other regulatory clearances in connection with the Offer.




                                          30
     Due Diligence Clean Team Protocol

     In addition, Sibanye-Stillwater and Lonmin have put in place a Due Diligence Clean Team
     Protocol which sets out how certain other confidential information that is competitively
     sensitive can be disclosed, used or shared between Sibanye-Stillwater and Lonmin and
     their professional advisers for the purposes of due diligence, synergies determination,
     evaluation, planning transition and regulatory clearances in connection with the Offer.

18   Opening Position Disclosure of interests in Lonmin
     As at the close of business on 13 December 2017 (being the last Business Day prior to the
     date of this Announcement) neither Sibanye-Stillwater, nor any of its directors, nor, so far as
     Sibanye-Stillwater is aware, any person acting in concert (within the meaning of the
     Takeover Code) with it has: (i) any interest in or right to subscribe for any relevant securities
     of Lonmin; or (ii) any short positions in respect of relevant Lonmin Shares (whether
     conditional or absolute and whether in the money or otherwise), including any short position
     under a derivative, any agreement to sell or any delivery obligation or right to require
     another person to purchase or take delivery: or (iii) borrowed or lent any relevant Lonmin
     Shares (including, for these purposes, any financial collateral arrangements of the kind
     referred to in Note 4 on Rule 4.6 of the Takeover Code), save for any borrowed shares
     which had been either on-lent or sold.

     “Interests in securities”, for these purposes, arise, in summary, when a person has long
     economic exposure, whether absolute or conditional, to changes in the price of securities
     (and a person who only has a short position in securities is not treated as interested in those
     securities). In particular, a person will be treated as having an “interest” by virtue of the
     ownership, voting rights or control of securities, or by virtue of any agreement to purchase,
     option in respect of, or derivative referenced to, securities.

     It has not been practicable for Sibanye-Stillwater to make enquiries of all of its concert
     parties in advance of the release of this Announcement. Therefore, all relevant details in
     respect of Sibanye-Stillwater’s concert parties will be included in the Opening Position
     Disclosure in accordance with Rule 8.1(a) and Note 2(a)(i) on Rule 8 of the Takeover Code.

19   General
     The Scheme Document and the Forms of Proxy accompanying the Scheme Document will
     be published in due course around the time that all relevant clearances from the competition
     and regulatory authorities, in particular those in South Africa and the United Kingdom (or, if
     applicable, the European Union, in case a referral is made to the European Commission
     pursuant to Article 22 of Council Regulation (EC) 139/2004), have been received. The
     Scheme Document and Forms of Proxy will be made available to all Lonmin Shareholders
     at no charge to them.

     The Sibanye-Stillwater Circular, containing (amongst other things) the notice of the Sibanye-
     Stillwater Shareholder Meeting (including the resolution to be adopted by the Sibanye-
     Stillwater Shareholders), together with the Forms of Proxy, will be posted to Sibanye-
     Stillwater Shareholders at or around the same time as the Scheme Document is published.
     The Sibanye-Stillwater Circular will be made available in due course by Sibanye-Stillwater
     on its website at www.sibanyestillwater.com/investors/transactions/lonmin and by Lonmin on
     its website at www.lonmin.com/investors/sibanye-stillwater-offer.

     Sibanye-Stillwater reserves the right to elect (subject to the consent of the Panel) to
     implement the Acquisition of the Lonmin Shares by way of a takeover offer as an alternative
     to the Scheme. In such event, the Acquisition will be implemented on substantially the same
     terms as those which would apply to the Scheme (subject to appropriate amendments,
     including an acceptance condition set at 90 per cent. of the Lonmin Shares to which such
     offer relates or such lesser percentage, being more than 50 per cent., as Sibanye-Stillwater
     may decide or the Panel may require).

     The Offer will be made on the terms and subject to the Conditions and further terms set out
     in Appendix I to this Announcement and included in the Scheme Document. The bases and
     sources of financial information and bases of calculations contained in this Announcement
     are set out in Appendix II to this Announcement. A summary of the irrevocable undertakings
     is contained in Appendix III to this Announcement. Appendix IV to this Announcement
     contains details of and bases of calculation of the anticipated financial benefits of the Offer.
     Certain terms used in this Announcement are defined in Appendix V to this Announcement.

     UBS, HSBC, Qinisele Resources, BDO, Gleacher Shacklock, J.P. Morgan Cazenove,
     Moshe Capital and Greenhill have each given and not withdrawn their consent to the
     publication of this Announcement, with the inclusion herein of the references to their names
     in the form and context in which they appear.

Further information
This Announcement is for information purposes only. It is not intended to and does not constitute,
or form part of, an offer, invitation or the solicitation of an offer to purchase, otherwise acquire,
subscribe for, sell or otherwise dispose of any securities, or the solicitation of any vote or approval
in any jurisdiction, pursuant to the Offer or otherwise, nor will there be any sale, issuance or
transfer of securities in any jurisdiction in contravention of applicable law.

The Offer will be made solely by means of the Scheme Document which, together with the Forms
of Proxy, will contain the full terms and conditions of the Offer including details of how to vote in
respect of the Offer.

This Announcement has been prepared 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 this Announcement had been prepared in accordance with the laws and regulations of
jurisdictions outside the United Kingdom.

Sibanye-Stillwater will prepare the Sibanye-Stillwater Circular to be distributed to Sibanye-
Stillwater Shareholders. Lonmin will prepare the Scheme Document to be distributed to Lonmin
Shareholders. Sibanye-Stillwater urges Lonmin Shareholders to read the Scheme Document
carefully when it becomes available because it will contain important information in relation to the
Offer, the New Sibanye-Stillwater Shares and the Enlarged Sibanye-Stillwater Group. Sibanye-
Stillwater urges Sibanye-Stillwater Shareholders to read the Sibanye-Stillwater Circular when it
becomes available because it will contain important information in relation to the New Sibanye-
Stillwater Shares. Any vote in respect of the resolutions to be proposed at the Court Meeting, the
Lonmin General Meeting and the Sibanye-Stillwater Shareholder Meeting to approve the Offer or
the allotment and issue of the New Sibanye-Stillwater Shares (as applicable) and related matters,
should be made only on the basis of the information contained in the Scheme Document and, in
the case of Sibanye-Stillwater Shareholders, the Sibanye-Stillwater Circular.

This Announcement does not constitute a prospectus or prospectus equivalent document.

Overseas shareholders

The release, publication or distribution of this Announcement in certain jurisdictions may be
restricted by law. Persons who are not resident in the United Kingdom or who are subject to other
jurisdictions should inform themselves of, and observe, any applicable requirements. Any failure to
comply with the applicable requirements may constitute a violation of the laws of any such
jurisdiction.

The Offer relates to shares of a UK company and is proposed to be effected by means of a
scheme of arrangement under the laws of England and Wales. A transaction effected by means of
a scheme of arrangement is not subject to proxy solicitation or tender offer rules under the US
Exchange Act. Accordingly, the Scheme is subject to the disclosure requirements, rules and
practices applicable in the United Kingdom to schemes of arrangement, which differ from the
requirements of US proxy solicitation or tender offer rules. However, if Sibanye-Stillwater were to
elect to implement the Offer by means of a takeover offer, such takeover offer will be made in
compliance with all applicable laws and regulations, including Section 14(e) of the US Exchange
Act and Regulation 14E thereunder. Such a takeover would be made in the United States by
Sibanye-Stillwater and no one else. In addition to any such takeover offer, Sibanye-Stillwater,
certain affiliated companies and the nominees or brokers (acting as agents) may make certain




                                                  35
purchases of, or arrangements to purchase, shares in Lonmin outside such takeover offer during
the period in which such takeover offer would remain open for acceptance. If such purchases or
arrangements to purchase were to be made they would be made outside the United States and
would comply with applicable law, including the US Exchange Act. Any information about such
purchases will be disclosed as required in the UK, will be reported to a Regulatory Information
Service of the UKLA and will be available on the London Stock Exchange website:
www.londonstockexchange.com.

Unless otherwise determined by Sibanye-Stillwater or required by the Takeover Code, and
permitted by applicable law and regulation, the Offer will not be made, directly or indirectly, in, into
or from a Restricted Jurisdiction where to do so would violate the laws in that jurisdiction, and the
Offer will not be capable of acceptance from or within a Restricted Jurisdiction. Accordingly, copies
of this Announcement and all documents relating to the Offer are not being, and must not be,
directly or indirectly, mailed, transmitted or otherwise forwarded, distributed or sent in, into or from
a Restricted Jurisdiction where to do so would violate the laws in that jurisdiction, and persons
receiving this Announcement and all documents relating to the Offer (including custodians,
nominees and trustees) must not mail or otherwise distribute or send them in, into or from such
jurisdictions where to do so would violate the laws in that jurisdiction.

The availability of the Offer to Lonmin Shareholders who are not resident in the United Kingdom
may be affected by the laws of the relevant jurisdictions in which they are resident. Persons who
are not resident in the United Kingdom should inform themselves of, and observe, any applicable
requirements.

The New Sibanye-Stillwater Shares may not be offered, sold or delivered, directly or indirectly, in,
into or from any Restricted Jurisdiction or to, or for the account or benefit of, any Restricted
Overseas Persons except pursuant to an applicable exemption from, or in a transaction not
subject to, applicable securities laws of those jurisdictions.

The New Sibanye-Stillwater Shares, which will be issued in connection with the Offer, have not
been, and will not be, registered under the US Securities Act or under the securities law of any
state, district or other jurisdiction of the United States. Accordingly, the New Sibanye-Stillwater
Shares may not be offered, sold, resold, delivered, distributed or otherwise transferred, directly or
indirectly, in or into or from the United States absent registration under the US Securities Act or an
exemption therefrom. The New Sibanye-Stillwater Shares are expected to be issued in reliance
upon the exemption from the registration requirements of the US Securities Act provided by
Section 3(a)(10) thereof. Lonmin Shareholders (whether or not US persons) who are or will be
affiliates (within the meaning of the US Securities Act) of Sibanye-Stillwater or Lonmin prior to, or
of Sibanye-Stillwater after, the Effective Date will be subject to certain US transfer restrictions
relating to the New Sibanye-Stillwater Shares received pursuant to the Scheme. For the purposes
of qualifying for the exemption from the registration requirements of the US Securities Act afforded
by Section 3(a)(10), Lonmin will advise the Court that its sanctioning of the Scheme will be relied
upon by Sibanye-Stillwater as an approval of the Scheme following a hearing on its fairness to
Lonmin Shareholders.

The receipt of New Sibanye-Stillwater Shares pursuant to the Offer by a US Lonmin 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 Lonmin Shareholder is urged to consult his
independent professional adviser immediately regarding the tax consequences of the Offer.

It may be difficult for US Lonmin Shareholders to enforce their rights and claims arising out of the
US federal securities laws, since Sibanye-Stillwater and Lonmin are located in countries other than




                                                  36
the United States, and some or all of their officers and directors may be residents of countries
other than the United States. US Lonmin 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 this Announcement 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 this Announcement. Any representation to the contrary is a criminal
offence in the United States

The Offer will be subject to the applicable requirements of the Takeover Code, the Panel, the
London Stock Exchange, the Financial Conduct Authority, the UKLA and the Johannesburg Stock
Exchange.

              Wider Lonmin Group to an extent which is material in the context of the
              Wider Lonmin Group taken as a whole; or

      (v)     no steps having been taken and no omissions having been made which are
              likely to result in the withdrawal, cancellation, termination or modification of
              any licence held by any member of the Wider Lonmin Group which is
              necessary for the proper carrying on of its business and the withdrawal,
              cancellation, termination or modification of which might reasonably be
              expected to have a material adverse effect on the Wider Lonmin Group
              taken as a whole;

No discovery of certain         matters      regarding    information,      liabilities   and
environmental issues
(l)   except as Disclosed, Sibanye-Stillwater not having discovered:

      (i)     that any financial, business or other information concerning the Wider
              Lonmin Group publicly announced prior to this date of the Announcement
              or disclosed at any time to any member of the Wider Sibanye-Stillwater
              Group by or on behalf of any member of the Wider Lonmin Group prior to
              the date of this Announcement is misleading, contains a material
              misrepresentation of any fact, or omits to state a fact necessary to make
              that information not misleading, in any such case to a material extent in the
              context of the Wider Lonmin Group taken as a whole;

      (ii)    that any member of the Wider Lonmin Group or any partnership, company
              or other entity in which any member of the Wider Lonmin Group has a
              significant economic interest and which is not a subsidiary undertaking of
              Lonmin is subject to any liability, contingent or otherwise and which is
              material in the context of the Wider Lonmin Group taken as a whole;

      (iii)   that any past or present member of the Wider Lonmin Group has not
              complied in any material respect with all applicable legislation, regulations
              or other requirements of any jurisdiction or any Authorisations relating to
              the use, treatment, storage, carriage, disposal, discharge, spillage, release,
              leak or emission of any waste or hazardous substance or any substance
              likely to impair the environment (including property) or harm human or
              animal health or otherwise relating to environmental matters or the health
              and safety of humans, which non-compliance would be likely to give rise to
              any liability including any penalty for non-compliance (whether actual or
              contingent) on the part of any member of the Wider Lonmin Group which is
              material in the context of the Wider Lonmin Group taken as a whole;

      (iv)    that there has been a material disposal, discharge, spillage, accumulation,
              release, leak, emission or the migration, production, supply, treatment,
              storage, transport or use of any waste or hazardous substance or any
              substance likely to impair the environment (including any property) or harm
              human or animal health which (whether or not giving rise to non-
              compliance with any law or regulation) would be likely to give rise to any
              liability (whether actual or contingent) on the part of any member of the
              Wider Lonmin Group which is material in the context of the Wider Lonmin
              Group taken as a whole;




                                        50
 (v)      that there is or is reasonably likely to be any material obligation or liability
          (whether actual or contingent) or requirement to make good, remediate,
          repair, reinstate or clean up any property, asset or any controlled waters
          currently or previously owned, occupied, operated or made use of or
          controlled by any past or present member of the Wider Lonmin Group (or
          on its behalf), or in which any such member may have or previously have
          had or be deemed to have had an interest, under any environmental
          legislation, common law, regulation, notice, circular, Authorisation or order
          of any Third Party in any jurisdiction or to contribute to the cost thereof or
          associated therewith or indemnify any person in relation thereto which is
          material in the context of the Wider Lonmin Group taken as a whole; or

 (vi)     that circumstances exist (whether as a result of making the Offer or
          otherwise) which would be reasonably likely to lead to any Third Party
          instituting (or whereby any member of the Wider Lonmin Group would be
          likely to be required to institute), an environmental audit or taking any steps
          which would in any such case be reasonably likely to result in any actual or
          contingent liability to improve or install new plant or equipment or to make
          good, repair, reinstate or clean up any property of any description or any
          asset now or previously owned, occupied or made use of by any past or
          present member of the Wider Lonmin Group (or on its behalf) or by any
          person for which a member of the Wider Lonmin Group is or has been
          responsible, or in which any such member may have or previously have
          had or be deemed to have had an interest, which is material in the context
          of the Wider Lonmin Group taken as a whole;

          Lonmin Group or any person that performs or has performed services for or

          constitute an offence under the UK Bribery Act 2010, the US Foreign
          Corrupt Practices Act of 1977, as amended, or any other applicable anti-
          corruption legislation; or

 (viii)   any past or present member, director, officer or employee of the Wider
          Lonmin Group or any person that performs or has performed services for or
          on behalf of such company is engaging in or has at any time engaged in
          any act of bribery or has paid or agreed to pay any bribe including any
          “inducement fee” given or agreed to give any similar gift or benefit or paid

          as a whole; or



                                    51
            No criminal property
             (ix)      any asset of any member of the Wider Lonmin Group constitutes criminal
                       property as defined by Section 340(3) of the UK Proceeds of Crime Act
                       2002 (but disregarding paragraph (b) of that definition).

Part B: Certain further terms of the Offer

1    Subject to the requirements of the Panel, Sibanye-Stillwater reserves the right to waive:

     (i)     any of the Conditions set out in the above Condition 2 for the timing of the Court
             Meeting, the Lonmin General Meeting and the Court hearing to sanction the Scheme
             and the effectiveness of the Scheme. If any such deadline is not met, Sibanye-
             Stillwater will make an announcement by 8.00 am (London time) on the Business
             Day following such deadline confirming whether it has invoked or waived the
             relevant Condition or agreed with Lonmin to extend the deadline in relation to the
             relevant Condition; and

     (ii)    in whole or in part, all or any of the above Conditions 3(c) to (l) (inclusive) of Part A
             of this Appendix I to this Announcement.

2    If Sibanye-Stillwater is required by the Panel to make an offer for Lonmin Shares under the
     provisions of Rule 9 of the Takeover Code, Sibanye-Stillwater may make such alterations to
     any of the above Conditions and terms of the Offer as are necessary to comply with the
     provisions of that Rule.

3    The Offer will lapse if:

     (i)     insofar as the Offer or any matter arising from or relating to the Scheme or Offer
             constitutes a concentration with a Community dimension within the scope of the
             Regulation, or the CMA refers the Offer to the European Commission pursuant to
             Article 22(1) of the Regulation and the European Commission decides to examine
             the Offer pursuant to Article 22(3) of the Regulation, the European Commission
             initiates proceedings under Article 6(1)(c) of the Regulation; or

     (ii)    insofar as the Offer or any matter arising from the Scheme or Offer does not
             constitute a concentration with a Community dimension within the scope of the
             Regulation, the Scheme or Offer or any matter arising from or relating to the Offer
             becomes subject to a CMA Phase 2 Reference,

     in each case, before the date of the Court Meeting.

4    Sibanye-Stillwater will be under no obligation to waive (if capable of waiver), to determine to
     be or remain satisfied or to treat as fulfilled any of Conditions 3(c) to (l) (inclusive) of Part A
     of this Appendix I to this Announcement by a date earlier than the latest date for the
     fulfilment of that Condition notwithstanding that the other Conditions of the Offer may at
     such earlier date have been waived or fulfilled and that there are at such earlier date no
     circumstances indicating that any of such Conditions may not be capable of fulfilment.

5    The Lonmin Shares acquired under the Offer will be acquired fully paid and free from all
     liens, equities, charges, encumbrances, options, rights of pre-emption and any other third
     party rights and interests of any nature and together with all rights now or hereafter
     attaching or accruing to them, including, without limitation, voting rights and the right to



                                                 52
    receive and retain in full all dividends and other distributions (if any) declared, made or paid,
    or any other return of capital (whether by reduction of share capital or share premium
    account or otherwise) made, on or after the date of this Announcement.

6   If, after the date of this Announcement but prior to the Effective Date, any dividend,
    distribution or other return of value is proposed, declared, paid or made or becomes payable
    by Lonmin and with a record date on or before the Effective Date, Sibanye-Stillwater
    reserves the right (without prejudice to any right Sibanye-Stillwater may have, with the
    consent of the Panel, to invoke Condition 3(j)(ii) of Part A of this Appendix I to this
    Announcement) to adjust the Exchange Ratio downwards to reflect the aggregate amount of
    such dividend, distribution or other return of value.

    If any such dividend, distribution or other return of value is paid or made before the Effective
    Date and Sibanye-Stillwater exercises its rights under this paragraph to adjust the Exchange
    Ratio, any reference in this Announcement to the Exchange Ratio will be deemed to be a
    reference to the Exchange Ratio as so adjusted.

    To the extent that such a dividend, distribution or other return of value has been declared or
    announced but not paid or made or is not payable by reference to a record date prior to the
    Effective Date or will be: (i) transferred pursuant to the Offer on a basis which entitles
    Sibanye-Stillwater to receive the dividend or distribution and to retain it; or (ii) cancelled, the
    Exchange Ratio will not be subject to any adjustment in accordance with this paragraph 6.

    Sibanye-Stillwater also reserves the right to adjust the Exchange Ratio in such
    circumstances as are, and by such amount as is, permitted by the Panel.

    Any exercise by Sibanye-Stillwater of its rights referred to in this paragraph will be the
    subject of an announcement and, for the avoidance of doubt, will not be regarded as
    constituting any revision or variation of the Offer.

7   If, after the date of this Announcement, Sibanye-Stillwater issues new Sibanye-Stillwater
    Shares on a pre-emptive basis at a discount greater than ten per cent. to the closing price of
    a Sibanye-Stillwater Share on the day immediately preceding the announcement, unless
    Sibanye-Stillwater and Lonmin otherwise agree, the Exchange Ratio shall be adjusted to
    ensure that Lonmin Shareholders are not disadvantaged by the dilution arising from such
    pre-emptive issue. This adjustment shall be calculated by reference to the bonus factor as
    reflected in the calculation of the TERP.

8   Sibanye-Stillwater reserves the right to elect (subject to the consent of the Panel) to
    implement the acquisition of the Lonmin Shares by way of a takeover offer as an alternative
    to the Scheme. In such event, the acquisition will be implemented on substantially the same
    terms as those which would apply to the Scheme (subject to appropriate amendments,
    including an acceptance condition set at 90 per cent. of the shares to which such offer
    relates or such lesser percentage, being more than 50 per cent., as Sibanye-Stillwater may
    decide or the Panel may require).

9   The availability of the Offer to persons not resident in the United Kingdom may be affected
    by the laws of the relevant jurisdictions. Persons who are not resident in the United Kingdom
    should inform themselves about and observe any applicable requirements. The New
    Sibanye-Stillwater Shares to be issued pursuant to the Offer have not been, and will not be,
    registered under the US Securities Act nor under any of the relevant securities laws of any




                                                53
     Restricted Jurisdiction. Accordingly, the New Sibanye-Stillwater Shares may not be offered,
     sold or delivered, directly or indirectly, in the United States or any Restricted Jurisdiction
     except pursuant to exemptions from applicable requirements of any such jurisdiction.

10   The Offer is not being made, directly or indirectly, in, into or from, or by use of the mails of,
     or by any means or instrumentality (including, but not limited to, facsimile, e-mail or other
     electronic transmission, telex or telephone) of interstate or foreign commerce of, or of any
     facility of a national, state or other securities exchange of, any jurisdiction where to do so
     would violate the laws of that jurisdiction.

11   The Offer is governed by the laws of England and Wales and is subject to the jurisdiction of
     the English Courts and to the Conditions and further terms set out in this Appendix I to this
     Announcement and to be set out in the Scheme Document. The Offer will be subject to the
     applicable requirements of the Takeover Code, the Panel, the London Stock Exchange, the
     Financial Conduct Authority, the UKLA and the Johannesburg Stock Exchange. The New
     Sibanye-Stillwater Shares will be issued credited as fully paid and will rank pari passu in all
     respects with the Sibanye-Stillwater Shares.

12   Each of the Conditions will be regarded as a separate Condition and will not be limited by
     reference to any other Condition.

                                APPENDIX II
              SOURCES OF INFORMATION AND BASES OF CALCULATION

(i)     The value placed by the Offer and attributed to the entire share capital of Lonmin is
        calculated:

        (a)     by reference to the price of R18.67 per Sibanye-Stillwater Share, being the 30
                trading day volume weighted average price of a Sibanye-Stillwater Share on the
                Johannesburg Stock Exchange for the period ended 13 December 2017 (being the
                last Business Day prior to this Announcement); and

        (b)     on the basis of the fully diluted number of Lonmin Shares in issue referred to in
                paragraph (iv) below.

(ii)    The percentage of the share capital of the Enlarged Sibanye-Stillwater Group that will be
        owned by Lonmin Shareholders (being 11.3 per cent.) is calculated by dividing the number
        of New Sibanye-Stillwater Shares to be issued pursuant to the terms of the Acquisition
        referred to in paragraph (vi)(b) below by the issued share capital of the Enlarged Sibanye-
        Stillwater Group (as set out in paragraph (vi) below) and multiplying the resulting sum by
        100 to produce a percentage.

(iii)   As at close of business on 13 December 2017 (being the last Business Day prior to this
        Announcement), Lonmin had in issue 282,784,288 Lonmin Shares and Sibanye-Stillwater
        had in issue 2,168,721,220 Sibanye-Stillwater Shares.

(iv)    The fully diluted share capital of Lonmin (being 284,938,946 Lonmin Shares) is calculated
        as the sum of:

        (a)     the number of Lonmin Shares referred to in paragraph (iii) above; and

        (b)     any further Lonmin Shares which may be issued on or after the date of this
                Announcement on the exercise of options or vesting of awards under the Lonmin
                Share Plans granted on or before this Announcement, amounting in aggregate to
                2,203,859 Lonmin Shares, less any Lonmin Shares held in the Lonmin Employee
                Benefit Trust (being 49,201 Lonmin Shares).

(v)     On the date of this Announcement, neither Lonmin nor Sibanye-Stillwater hold any shares in
        treasury.

(vi)    The share capital of the Enlarged Sibanye-Stillwater Group (being 2,444,257,181) has been
        calculated as the sum of:

        (a)     2,168,721,220 Sibanye-Stillwater Shares, being the number of Sibanye-Stillwater
                Shares in issue as at close of business on 13 December 2017 (being the last
                Business Day prior to this Announcement); and

        (b)     275,535,961 New Sibanye-Stillwater Shares which would be issued pursuant to the
                terms of the Acquisition (being 0.967 New Sibanye-Stillwater Shares to be issued
                per Lonmin Share multiplied by the fully diluted share capital of Lonmin as set out
                in paragraph (iv) above).

(vii)   The premium calculations to the price per Lonmin Share have been calculated by reference
        to:




                                                 55
         (a)     the closing price of R16.11 per Sibanye-Stillwater Share and of 63.8 pence per
                 Lonmin Share on 13 December 2017 (being the last Business Day prior to this
                 Announcement); and

         (b)     the prior 30 trading day volume weighted average price of a Sibanye-Stillwater
                 Share of R18.67 and of a Lonmin Share of 71.1 pence (since 2 November 2017 to
                 13 December 2017).

       -      the lapse or withdrawal either is not confirmed by Sibanye-Stillwater or is followed
              within five Business Days by an announcement under Rule 2.7 of the Takeover Code

                                  APPENDIX IV
                   STATEMENT ON QUANTIFIED FINANCIAL BENEFITS

                                             PART A
Sibanye-Stillwater has made the following quantified financial benefits statement in paragraph 3 of
the Announcement (the “Quantified Financial Benefits Statement”):

      “The Board of Sibanye-Stillwater believes that, as a direct result of the Acquisition, there are
      a number of areas where the Enlarged Sibanye-Stillwater Group could benefit from
      attractive synergies, creating additional value for Sibanye-Stillwater Shareholders. Sibanye-
      Stillwater has demonstrated its ability to extract synergies from the recently acquired
      Aquarius Platinum and Rustenburg Operations. Sibanye-Stillwater has already realised
      R550 million per annum in annualised operational synergies as at 30 June 2017 from the
      Aquarius Platinum and Rustenburg Operations acquisitions and is expected to realise
      approximately R1,000 million of annualised synergies by 2018.

      Sibanye-Stillwater has identified expected total pre-tax run-rate synergies of approximately
      R1,500 million by 2021, averaging approximately R1,280 million per annum for the period
      2021 to 2032, as a result of the Acquisition, including:

      -       in relation to overhead services, a total of approximately R730 million per annum by
              2021, with respect to:

              -        shared services between members of the Enlarged Sibanye-Stillwater
                       Group;

              -        overhead costs in respect of management and marketing;

              -        shared mining services; and

              -        shared corporate and regulatory costs;

      -       in relation to processing synergies, a total of approximately R780 million per annum
              by 2021, averaging approximately R550 million per annum for the period 2021 to
              2032, primarily by utilising spare capacity within Lonmin’s smelting and refining
              infrastructure to process concentrate produced by the Rustenburg Operations.

      These savings from overhead synergies and reduced processing costs are separate from
      those matters contained in Lonmin’s Operational Review (as described in paragraph 4 of
      this Announcement) and those matters addressed in Lonmin’s evolving business plan (as
      described in paragraph 8 of this Announcement).

      Sibanye-Stillwater estimates that the implementation of the overhead synergies would give
      rise to expected one-off costs of approximately R80 million and a headcount reduction of
      approximately 700. In addition, implementation of the processing synergies would give rise
      to expected one-off costs of approximately R1,000 million, such one-off costs to be incurred
      primarily in relation to the construction of an additional smelting furnace and Sibanye-
      Stillwater will continue to explore other ways to mitigate such one-off costs.

      Aside from such one-off costs referred to above, Sibanye-Stillwater does not expect any
      material dis-synergies to arise in connection with the Acquisition.”

Reports




                                                 58
The Sibanye-Stillwater Board believes that the Enlarged Sibanye-Stillwater Group should be able
to achieve the synergies set out in the Quantified Financial Benefits Statement.

As required by Rule 28.1(a) of the Takeover Code, BDO, as reporting accountants to Sibanye-
Stillwater, have provided a report stating that, in their opinion, the Quantified Financial Benefits
Statement has been properly compiled on the basis stated.

In addition, UBS and HSBC, as financial advisers to Sibanye-Stillwater, have provided a report
stating that, in their view, the Quantified Financial Benefits Statement has been prepared with due
care and consideration.

Copies of these reports are included in Part B and Part C of this Appendix IV to this
Announcement.

Each of BDO, UBS and HSBC has given and not withdrawn its consent to the publication of its
report in this Announcement in the form and context in which it is included.

Bases of calculation of the quantified financial benefits statement

In preparing the Quantified Financial Benefits Statement, Lonmin has provided Sibanye-Stillwater
with certain operating and financial information to facilitate a detailed analysis in support of
evaluating the potential synergies available from the Acquisition.

Baseline cost numbers were agreed based on the underlying business plans of both Sibanye-
Stillwater and Lonmin for their budgeted 2018 financial years with reference to the available
financials for their 2017 financial years and, for the synergies arising from the combination of
group functions, organisation information was reviewed.

The assessment and quantification of the potential synergies have in turn been informed by
Sibanye-Stillwater management’s industry experience as well as their experience of executing and
integrating past acquisitions and discussions with Lonmin management who have undertaken a
number of cost reduction exercises.

Cost saving assumptions were based on a detailed, bottom-up evaluation of the benefits available
from elimination of duplicate activities, the leverage of combined scale economics and operational
efficiencies arising from consolidation of activities within operational facilities. In determining the
estimate of costs savings achievable through the combination of Sibanye-Stillwater and Lonmin,
no savings relating to operations have been included where no overlap exists.

In general, the synergy assumptions have in turn been risk adjusted, exercising a degree of
prudence in the calculation of the estimated synergy benefit set out above.

The Sibanye-Stillwater Board has, in addition, made the following assumptions, all of which are
outside the influence of Sibanye-Stillwater:

-     there will be no material impact on the underlying operations of either company or their
      ability to continue to conduct their businesses;

-     there will be no material change to macroeconomic, political, regulatory or legal conditions
      in the markets or regions in which Sibanye-Stillwater and Lonmin operate that materially
      impact on the Sibanye-Stillwater and Lonmin business plans and the implementation or
      costs to achieve the proposed cost savings;

-     there will be no material change in current foreign exchange rates and the spot rates for
      commodity prices contained in Sibanye-Stillwater’s business plans;




                                                  59
-     there will be no change in tax legislation or tax rates or other legislation or regulation in the
      countries in which Sibanye-Stillwater and Lonmin operate that could materially impact the
      ability to achieve any benefits; and

-     there will be no material regulatory impediment to the realisation of the synergies.

This analysis assumes no business disposals pursuant to the Acquisition.

Where appropriate, assumptions were used to estimate the costs of implementing the new
structures, systems and processes required to realise the synergies, including retrenchment costs
to achieve overhead synergies and capital outlays to achieve processing synergies.

Important notes

1.   The statements of estimated cost savings and synergies relate to future actions and circumstances
     which, by their nature, involve risks, uncertainties and contingencies. As a result, the cost savings
     and synergies referred to may not be achieved, may be achieved later or sooner than
     estimated, or those achieved could be materially different from those estimated. No statement
     in the Quantified Financial Benefits Statement, or this Announcement generally, should be
     construed as a profit forecast or interpreted to mean that Sibanye-Stillwater’s earnings in the
     first full year following the Offer, or in any subsequent period, would necessarily match or be
     greater than or be less than those of Sibanye-Stillwater and/or Lonmin for the relevant
     preceding financial period or any other period.

2.   Due to the scale of the Enlarged Sibanye-Stillwater Group, there may be additional changes
     to the Enlarged Sibanye-Stillwater Group’s operations. As a result, and given the fact that the
     changes relate to the future, the resulting cost savings may be materially greater or less than
     those estimated.

3.   In arriving at the estimate of synergies set out in this Announcement, the Sibanye-Stillwater
     Board has assumed that there will be no significant impact on the business of the Enlarged
     Sibanye-Stillwater Group.

respectively) and the basis of preparation of the Statement and notes to the Statement set out in

Save for any responsibility which we may have to those persons to whom this report is expressly
addressed and for any responsibility arising under Rule 28.1(a)(i) of the City Code to any person
as and to the extent there provided (including to the shareholders of the Company), to the fullest

Basis of opinion

We conducted our work in accordance with the Standards for Investment Reporting issued by the

whether the Statement has been accurately computed based upon bases of belief (including the
principal assumptions and sources of information summarised in the notes to the Statement).
Whilst the bases of belief (and the principal assumptions and sources of information summarised
in the notes to the Statement) are the responsibility of the Directors, we considered whether there
was anything to indicate whether the bases of belief (or principal assumptions or sources of
information summarised in the notes to the Statement) adopted by the Directors which, in our
opinion, are necessary for a proper understanding of the Statement, have not been disclosed or if
any of the bases of belief (or principal assumptions or sources of information summarised in the
notes to the Statement) made by the Directors appears to us to be unrealistic. This involved
discussing the Statement together with the bases of belief supporting the Statement (including the
principal assumptions and sources of information summarised in the notes to the Statement) with
the Directors and those officers and employees of the Company who developed the underlying
plans and with UBS Limited and HSBC Bank plc. The Statement is subject to uncertainty as
described in the important notes to the Statement.

We do not express any opinion as to the achievability of the synergy benefits estimated by
Directors of the Company in the Statement.

Our work has not been carried out in accordance with auditing or other standards and practices
generally accepted in the United States of America or other jurisdictions outside the United
Kingdom and accordingly should not be relied upon as if it had been carried out in accordance with
those standards and practices.

Opinion

In our opinion the Statement by the Company has been properly compiled on the basis stated.
