WHEREAS Investor NewCo has entered into the Business Combination Agreement,

                                   2

or IPO of the shareholding of the Parties in Investor NewCo.

financial investor ("THIRD PARTY INVESTOR").

and provisions contained herein, the Parties hereto agree as follows:

4.3      [Intentionally left blank]

4.4      [Intentionally left blank]

4.5      DRAG ALONG

         At any time after September 30, 2004, either ACP or GS, subject to the
         limitations set forth in the following paragraph, can require that the
         Financial Investors jointly sell their shares in Investor NewCo upon
         the same terms and conditions as apply to the Party imposing such
         requirement (provided that in no event can the other party be required
         to become subject to a non-compete covenant), subject to satisfaction
         of each of the following conditions:

         (i)      the sale of such shares occurs in compliance with the
                  Shareholders' Agreement (in particular Sec. 22 and 23) and the
                  Articles of Association of Investor NewCo, provided that each
                  Party hereby waives for the purposes of such sale its right to
                  be offered the shares of the other Party under Sec. 22 subsec.
                  2 of the Shareholders' Agreement; and

         (ii)     the proceeds of such sale result for the Party on which such
                  requirement is imposed in an internal rate of return
                  (calculated in accordance with Sec. 25 subsec. 3 of the
                  Shareholders' Agreement but in all events without taking into
                  account any tax on income or capital gains and treating any
                  withholding tax on distributions to such party as if they were
                  not withheld) of more than 30% p.a.; and

         (iii)    such sale relates to all of the shares of the Financial
                  Investors; and

         (iv)     the purchase price for the sale of the shares shall not be
                  less than the medium between the valuations found by two
                  reputable international investment banks (one of which shall
                  be selected by ACP and one of which shall be selected by GS)
                  (fairness opinions); and

         (v)      if reasonably requested by GS or ACP (in which case the
                  Parties shall consider waiving the requirement to obtain one
                  or both of the fairness opinions under (iv) above), a
                  competitive or structured solicitation of bids will be
                  conducted by an investment bank mutually agreed upon between
                  the Parties, with a view towards determining or confirming the
                  market value of the shares.



<Page>


                                       5


         Notwithstanding the foregoing, GS shall not be entitled to require a
         joint sale of the shares of Investor NewCo as provided in this Section
         4.5 until after November 1, 2005.

         In the event that the realization by the Financial Investors of their
         interest in Investor NewCo is sought to be achieved, at the initiative
         of either Party, through a sale of all or substantially all of the
         assets of Investor NewCo and its direct or indirect subsidiaries (taken
         as a whole) or any similar transactions or series of transactions
         effected at the level at or below Investor NewCo, the requirements set
         forth in (i)-(v) above shall apply to such transactions, mutatis
         mutandis.

         For the avoidance of doubt, this clause does not apply in the event of
         an IPO in which less than 75% of the shares are sold.

4.6      EXERCISE OF RIGHTS UNDER THE SHAREHOLDERS' AGREEMENT

         The Shareholders' Agreement extends certain exit rights to the
         Financial Investors individually as parties to the Shareholders'
         Agreement or jointly as financial investors. The Parties agree that
         they will use reasonable best efforts to exercise such rights only
         after mutual consultation. In addition, the Financial Investors agree
         to exercise certain of such rights only as follows:

         4.6.1    RIGHT TO INITIATE A SALE

                  (a)     ACP and, subject to the provisions of Section 4.6.1(b)
                          below, GS shall be free to exercise their rights under
                          Sec. 22.2 of the Shareholders' Agreement individually,
                          provided, however, (i) that the purchaser agrees to be
                          bound by the terms of this Agreement and assumes as a
                          joint and several debtor the obligations of the
                          selling Financial Investor under this Agreement and
                          the Shareholders' Agreement, (but none of the rights)
                          and (ii) that such sale does not trigger a Change of
                          Control under the Financing Agreements, and (iii) if
                          and to the extent that the other Financial Investor
                          does not exercise its right to co-sell, the amount of
                          shares sold shall be limited so as not to preclude the
                          other Financial Investor from selling at a later time
                          an equal amount of shares (in which sale the Financial
                          Investor selling shares in the first place shall not
                          have a right to co-sell) without triggering a Change
                          of Control under the Financing Agreements, except that
                          such limitation shall not apply in the event that the
                          Financing Banks have waived such potential Change of
                          Control or have allowed the purchaser in such sale to
                          be substituted for GS in the definition of a Change of
                          Control included in the Financing Agreements.

                                       6


                          The requirements in clauses (i), (ii) and (iii) do not
                          apply to the transaction contemplated by clause 4.5.

                  (b)     Until the earlier of the Expiry of the ACP Restriction
                          Period and September 30, 2005, GS shall not exercise
                          its right to initiate a sale under Sec. 22.2 of the
                          Shareholders' Agreement, unless (i) after giving
                          effect to such sale GS continues to beneficially own
                          at least 16% of the shares of Investor NewCo then
                          outstanding and (ii) the level of control that GS and
                          its appointees to the Governing Bodies have with
                          respect to Investor NewCo is not diminished in any
                          material respect as a result of or in connection with
                          such sale and no agreement or understanding between GS
                          and the purchaser shall affect the independence of GS
                          in taking decisions in the Shareholders' Meeting of
                          Investor NewCo or of its appointees in the Governing
                          Bodies.

         4.6.2    RIGHT TO DRAG ALONG MIG

                  The Financial Investors agree that they will support each
                  other in exercising the rights extended to the Financial
                  Investors as group to drag along MIG upon the request of the
                  Financial Investors (Sec. 28.1 of the Shareholders'
                  Agreement), if such Financial Investor is entitled to drag
                  along the other Financial Investor under Sec. 4.5. If the
                  requirements under Sec. 4.5 above are not met, the Financial
                  Investors can only exercise this right under Sec. 28.1 of the
                  Shareholders' Agreement as mutually agreed.

         4.6.3    COOPERATION

                  The Parties agree that they cooperate and use their influence
                  to cause Investor NewCo to take appropriate actions, including
                  the providing of the necessary information, to enable each
                  Party to make an informed decision on the rights referred in
                  Sec. 4.5 and 4.6 above and Sec. 4.7 below.

4.7      IPO

         From and after June 30, 2003, ACP shall have the right, and from and
         after September 30, 2005, ACP and GS shall each have the right to
         require that the other Financial Investors join with it in its demand
         to initiate an IPO under Sec. 20 subsec. 1 of the Shareholders'
         Agreement. In all events ACP and GS shall reasonably consult with each
         other prior to requesting an IPO.

                                       7


         The Parties shall support each other if either of the Parties requests
         a secondary offering under Sec. 20.5 of the Shareholders' Agreement. As
         between the Parties, each of the Parties shall have the right to sell a
         pro rata amount of their existing shareholding in Investor NewCo
         pursuant to any such secondary offering.

4.8      INVESTOR NEWCO AS KGaA

         All exit rights granted hereunder shall extend mutatis mutandis to the
         shares in Investor NewCo as well as to the shares in its general
         partner.

4.9      CLARIFICATION

         For the avoidance of doubt it is clarified that Sec. 4.2 above shall
         apply to all rights and transfers provided for herein.

ARTICLE 5 - EXERCISE OF VOTING RIGHTS

5.1      Except as otherwise provided below, after the Expiry of the ACP
         Restriction Period the Financial Investors shall pool their votes in
         the Shareholders' Meeting of Investor NewCo, and in addition thereto to
         the extent legally permissible, the votes of their appointees in the
         Governing Bodies. They will consult with each other sufficiently prior
         to any Shareholders' Meeting of Investor NewCo or meeting of the
         Governing Bodies to find a common position on the actions and
         resolutions to be considered. Should the Financial Investors fail to
         agree on the joint exercise of their voting rights on a particular
         subject matter, the Financial Investors shall exercise their voting
         rights and shall instruct their appointees to the Governing Bodies to
         exercise their voting rights in accordance with the suggestions made by
         ACP.

5.2      The provisions of Sec. 5.1 above shall not apply to any actions and
         resolutions which require a 75% or higher majority vote or approval of
         the applicable Governing Body after giving effect of the provisions of
         the Shareholders' Agreement. This Sec. 5.2 does not apply to actions
         and resolutions as to which Sec. 5.3 (5) below applies, irrespective of
         the threshhold set forth in Sec. 5.3 (5) below. The provision in Sec.
         14.2 sentence 2 of the Shareholders' Agreement shall remain unaffected.

5.3      Notwithstanding Sec. 5.1 above, the Financial Investors agree that,
         after the Expiry of the Restriction Period, the Financial Investors
         shall mutually agree in advance on their common position with respect
         to any action, approval, authorization or decision taken by or
         submitted to the


<Page>


                                       8


         Shareholders' Meeting of Investor NewCo or to any of the Governing
         Bodies regarding any of the following matters:

         (1)      any removal, replacement or appointment of any individual as
                  the Chief Executive Officer of MGG or the Chief Financial
                  Officer of MGG;

         (2)      the exercise or discharge by Investor NewCo, MGG or any Messer
                  Group Company of any right or obligation under, or the waiver
                  or amendment of any provision of, any of Sections 4.22, 4.23,
                  4.24, 4.26 or 6.16 of the BCA (or any relevant definitions
                  contained in Sec. 1 of the BCA), and any other actions or
                  decisions by or on behalf of Investor NewCo, MGG or any Messer
                  Group Company relating to any of the matters referred to in
                  such Sections of the BCA;

         (3)      any actions or decisions by Investor NewCo, MGG or any Messer
                  Group Company under or relating to the MGG Compliance Program
                  (as defined in the BCA);

         (4)      any actions, transactions or decisions by Investor NewCo, MGG
                  or any Messer Group Company which could reasonably be expected
                  to involve the engagement by any of such entities, including
                  without limitation through any acquisition or investment, in
                  any Undesired Business Activities (as defined in the BCA) or
                  any activities which, due to legal or regulatory developments
                  subsequent to the date hereof, GS reasonably requests be
                  treated as Undesired Business Activities;

         (5)      any acquisition of or investment in any asset, entity or
                  business (other than an existing Messer Group Company) by
                  Investor NewCo, MGG or any Messer Group Company for
                  consideration (including the direct or indirect assumption of
                  liabilities) in excess of Euro 100,000,000.

         Should the Financial Investors fail to agree on a common position on a
         particular action or resolution relating to any of the matters
         described in this Sec. 5.3(1)-(5), they shall vote their shares and
         cause their appointees on the Governing Bodies to vote against such
         particular action or resolution.

5.4      Subject to compliance with the last paragraph of Section 4.5, if ACP
         proposes adoption of a resolution under Sec. 16 subsec. 2 (e) of the
         Shareholders' Agreement (sale of shares in MGG), GS agrees to vote


<Page>


                                       9


         in favor of such resolution, regardless of whether prior or after the
         Expiry of the ACP Restriction Period.

ARTICLES 6 - SYNDICATION

The Parties agree that they intend to syndicate shares in Investor NewCo subject
to the limitations of the Shareholders' Agreement and the Equity Commitment
Letter. The Parties shall mutually agree on the terms and conditions of such
syndication. In the event of any such syndication, the Parties shall transfer to
one or more third party investor(s) an equal amount of shares (as between ACP
and GS). The Financial Investors agree that they will negotiate with the third
party investors along the following lines:

(i)      third party investor has no right to initiate a sale or an IPO,

(ii)     third party investor can be dragged by ACP and GS if they sell jointly,
