C.          WHEREAS,  in  order  to  regulate  their  internal  relationship  as
            shareholders of the Company,  the Shareholders  intend to enter into
            this   shareholders'   agreement   including   its   exhibits   (the
            "Agreement").

Now, therefore, the Parties agree as follows:

1.          Articles of Association

            If any  provisions of the Articles of  Association  (Satzung) of the
            Company (the "Articles of Association") which are attached hereto as
            Exhibit  1  at  any  time  conflict  with  any  provisions  of  this
            Agreement, the provisions of this Agreement shall, as far as legally
            permitted,  prevail and the  Shareholders  shall exercise all rights
            conferred  upon them to procure  the  amendment  of the  Articles of
            Association  to the extent  necessary  to permit the Company and its
            affairs to be administered as provided for in this Agreement.

2.          Corporate Bodies of the Company

2.1         Corporate  Bodies.  The Company shall have the  following  corporate
            bodies:

            2.1.1   the "Shareholders' Meeting" (Gesellschafterversammlung); and

            2.1.2   the "Management Board" (Geschaftsfuhrung).

2.2         Employee  Co-determination.  It is the  Shareholders'  understanding
            that the Company  will not be subject to  employee  co-determination
            (Arbeitnehmermitbestimmung).

3.          Shareholdings in the Company

3.1         Shareholdings. The only shareholders in the Company shall be Bucyrus
            and Hamburg Trust.

3.2         Categories of Shares.  The Articles of Association shall provide for
            two categories of shares in the Company:  The share to be subscribed
            by Hamburg Trust (the "HT  Interest")  shall be qualified as A-class
            share (the "Class A Share"),  the share to be  subscribed by Bucyrus
            shall be qualified as B-class share (the "Class B Share").

3.3         Class A Share.  The Class A Share  shall  confer  upon its holder no
            voting  rights and shall not entitle its holder to dividend  rights.
            The participation of the Class A Share in liquidation proceeds shall
            be limited to a maximum amount of EUR  8,000,000.  The Class A Share
            shall confer upon its holder the consent rights described in Section
            4.3 and 8.3 and such  other  rights  attached  to such  share  under
            applicable mandatory law and the Articles of Association.

3.4         Class B Share.  The Class B Share shall  confer upon its holder such
            rights  as if it were the owner of  shares  conferring  100 % of the
            voting rights  subject only to the  limitations  resulting  from the
            stipulations  contained  in  Section  4.3 and  applicable  mandatory
            statutory  laws. The holder of the Class B Share shall have the sole
            right to resolve or to have resolved any  distribution  of dividends
            of DBT or the Company.

4.          Shareholders' Meeting

4.1         Matters for Shareholders' Meeting.  Except as otherwise provided for
            in this Agreement or by applicable  law, the  Shareholders'  Meeting
            shall  determine all matters  concerning the Company,  including but
            not  limited to the matters  listed in ss. 46 of the German  Limited
            Liability  Company Act (Gesetz  betreffend  die  Gesellschaften  mit
            beschrankter  Haftung).  In  particular,  but not  limited  to,  the
            Shareholders' Meeting shall resolve upon the following matters:

            4.1.1    amendments to the Articles of Association;

            4.1.2    establishment  of  and  any  amendments  to  the  Rules  of
                     Procedure for the Management Board (as defined below);

            4.1.3    consent to the annual  financial  statements  (Feststellung
                     des  Jahresabschlusses) and the appropriation of the profit
                     (Gewinnverwendung) of the Company;

            4.1.4    consent to the annual business plan  (Geschaftsplan) of the
                     Company including an operating budget;

            4.1.5    dissolution (Auflosung) of the Company;

            4.1.6    continuation of the dissolved Company;

            4.1.7    consent to the disposition of shares in the Company; and

            4.1.8    acts     under    the     German     Reorganization     Act
                     (Umwandlungsgesetz).

4.2         Voting Right. Subject to Sections 3.3 and 4.3 the Shareholders agree
            to exercise their influence on the Company  exclusively  through the
            Shareholders' Meeting.


                                       7

4.3         Consent  Rights  for Class A Share.  Bucyrus  may not  exercise  its
            voting  right and adopt  resolutions  without  the prior  consent of
            Hamburg Trust with respect to the following matters:

            4.3.1    any action by the  Company  or DBT that  would  result in a
                     breach of or deviation  from the Social Charter (as set out
                     in Section 15.2 of the SPA),  (the "Social  Charter") as in
                     force from time to time.  For the avoidance of doubt,  this
                     Section  4.3.1  shall  include,  without  limitation,   any
                     shareholders' resolutions consenting to acts to be taken by
                     the managing directors of the Company which would result in
                     a breach of or deviation from the Social Charter;

            4.3.2    any  amendments  to  the  Articles  of  Association  of the
                     Company or DBT to the extent such amendments  relate to the
                     Social Charter; and

            4.3.3    any  amendments  to  the  Articles  of  Association  of the
                     Company to the extent that such amendments adversely affect
                     the rights of Hamburg Trust as holder of the Class A Share.

4.4         Majority  Requirements.  Unless otherwise  provided for by mandatory
            law the  Shareholders'  Meeting  shall take all  decisions  with the
            majority of the votes cast.

4.5         Procedures.   To  the  extent   permitted   by  law,   Shareholders'
            resolutions   may  be  passed   without   convening  and  holding  a
            Shareholders'    Meeting   in   writing,    by   facsimile   or   by
            telecommunication  (e.g. by conference call or video  conference) if
            Bucyrus  gives its consent and  approval to such  procedure  and the
            information and participation rights of Hamburg Trust are met.

4.6         Rules and Regulations. Bucyrus as Shareholder with the prior written
            consent by Hamburg  Trust may establish  such rules and  regulations
            for the conduct of the Shareholders' Meetings, as it deems necessary
            or advisable, except insofar as any such rules and regulations would
            be inconsistent  with the provisions of applicable law, the Articles
            of Association or this Agreement.

4.7         Change of Seat.  It is  currently  intended  that the  Shareholders'
            Meeting  will  resolve  in due  course on a change of the  Company's
            registered seat from Dusseldorf to Essen.

5.          Management Board

5.1         Managing  Directors.  The  Management  Board  of the  Company  shall
            consist of [two] managing  directors  (Geschaftsfuhrer)  who in each
            case shall have the power to represent the Company  individually and
            who shall be exempted from the  limitations of ss. 181 of the German
            Civil Code (Burgerliches Gesetzbuch) except as resolved otherwise by
            the  Shareholders'  Meeting.  The managing  directors of the Company
            shall be


                                       8
<PAGE>

            appointed  and their  appointment  shall be revoked  exclusively  by
            Bucyrus.  For the  avoidance of doubt,  Hamburg Trust shall not have
            voting rights with regard to the  appointment  or the removal of any
            managing director and to their power to represent the Company.

5.2         Scope of Responsibilities.  The managing directors shall conduct the
            day-to-day  operations  of the Company  and,  notwithstanding  their
            legally  unlimited  authority  to bind  the  Company  towards  third
            parties,  shall  observe  the general  and  individual  instructions
            issued by the Shareholders' Meeting.

6.          Disposition of Shares in the Company

6.1         Transfer Restrictions.  Prior to the closing of the Forward Purchase
            Agreement (as defined below),  the Shareholders  mutually agree that
            neither  Bucyrus  nor  Hamburg  Trust  shall  transfer   (except  as
            otherwise provided  explicitly in this Section 6), the whole or part
            of its respective  shareholding in the Company (or DBT after merger)
            to any third  party.  Bucyrus is entitled  to  transfer  the Class B
            Share in full or in part to any  affiliate  of  Bucyrus  within  the
            meaning of Section 15 of the German Stock  Corporation Act (AktG) if
            such affiliate  undertakes vis-a-vis Hamburg Trust to adhere to this
            Agreement,  assume and comply with any  obligation  of Bucyrus under
            this  Agreement;  Section  7.2 last  sentence  shall  apply  mutatis
            mutandis  with respect to the  obligations  of the  transferee.  The
            Shareholders may not pledge or create an encumbrance  other than (i)
            in the case of Hamburg  Trust for the benefit of Bucyrus  (which may
            be  subordinated  according  to Section 3.4 of the Forward  Purchase
            Agreement)  and (ii) in the case of Bucyrus and Hamburg  Trust under
            the financing made available for the purpose of financing the shares
            in DBT or any refinancing thereof (the "Acquisition Financing") over
            the whole or part of their  shareholdings.  Bucyrus shall  indemnify
            Hamburg Trust for, and shall hold Hamburg Trust  harmless  from, any
            and all  liabilities  that may result from the breach of  applicable
            provisions  regarding  the  maintenance  of the share capital of the
            Company and repayment of any share  capital,  including  pursuant to
            Sections  30, 31 GmbHG if and to the extent  such breach (i) results
            in a benefit of Bucyrus, any affiliate of Bucyrus within the meaning
            of  section  15 of the German  Stock  Corporation  Act (AktG) or any
            third party being  attributed to Bucyrus or any of its affiliates or
            (ii) has been initiated by Bucyrus without Hamburg Trust's consent.

6.2         Change of Control in Company or Hamburg Trust.  If at any time after
            the  Signing  of  the  Transaction  and  until  the  Closing  of the
            Transaction,  (i) the  Class A Share is no  longer  held by  Hamburg
            Trust,  (ii) Professor Dr.  Heinrich M. Schulte is no longer able to
            exercise his all rights as  shareholder  of Hamburg  Trust (e.g.  in
            case of legal  incapacity -  Geschaftsunfahigkeit)  or no longer the
            sole  shareholder  of Hamburg Trust or no longer holds the shares in
            Hamburg   Trust  for  his  own  benefit  and  account  free  of  any
            entitlements  or rights of any third  parties  other  than  security
            interests  approved and requested by the Company or (iii)  Professor
            Dr. Heinrich M. Schulte is no longer


                                       9
<PAGE>

            able to act as  managing  director  of  Hamburg  Trust or not longer
            acting as the sole managing  director of Hamburg  Trust  irrevocably
            appointed until and including the Forward  Purchase Closing Date (as
            defined in the Forward Purchase  Agreement) with no intention of his
            dismissal  or  resignation  or (iv)  Hamburg  Trust has any  further
            operations or assets other than the Class A Share or has any further
            business  purpose other than to hold the Class A Share,  the Company
            is  required  under the SPA to inform  RCI in  writing  about  those
            changes without undue delay. Hamburg Trust undertakes to provide the
            Company this information without undue delay and Bucyrus and Hamburg
            Trust shall instruct the managing directors of the Company to convey
            the information to RCI in accordance with the terms of the SPA.

            Upon  receipt of such  information,  RCI may prior to the Closing of
            the  Transaction  request the sale and transfer of the Class A Share
            to RCI or such third party as RCI and Bucyrus  jointly  designate in
            writing as  acquirer  of the Class A Share (RCI or such third  party
            the "Transferee", Section 7.1.7 SPA). In case any event as described
            in the first sentence of this subpara. of Section 6.2 occurs Bucyrus
            is entitled to demand from  Hamburg  Trust and Hamburg  Trust hereby
            irrevocably  agrees that  Hamburg  Trust shall sell and transfer the
            Class A Share to the  Transferee.  The foregoing is an agreement for
            the  benefit of RCI in the meaning of Sec.  328 BGB (echter  Vertrag
            zugunsten Dritter).

7.1         Redemption provision.  The Articles of Association shall provide for
            the  right  of the  Company  to  redeem  the  Class  A  Share.  Such
            redemption  shall only be  possible  with prior  written  consent of
            Hamburg Trust except in the following cases:

            7.1.1    The Class A Share is partly or fully  seized by one or more
                     creditors  of  Hamburg  Trust  other than  Bucyrus  and its
                     affiliated  companies  within the  meaning of ss. 15 German
                     Stock Corporation Act (AktG); or

            7.1.2    Insolvency  or  similar   proceedings   are  instituted  in
                     relation to the assets of Hamburg Trust or the  institution
                     of such  proceedings  is applied  for by  Hamburg  Trust or
                     refused for reason of the lack of assets; or

            7.1.3    Hamburg Trust files a petition for judicial  dissolution of
                     or declares withdrawal from the Company.

            Hamburg  Trust hereby  irrevocably  consents to a redemption  of the
            Class A Share if (i) any of the  Assignment  Conditions set forth in
            Section 5.2 of the Forward Purchase  Agreement is fulfilled and (ii)
            the  Forward  Purchase  Price  according  to  the  Forward  Purchase
            Agreement  has not been paid to Hamburg Trust prior to the execution
            of the redemption  right by a corresponding  written  declaration of
            the Company's managing directors.

7.2         Redemption  compensation.  If and to the extent the Class A Share is
            redeemed  Hamburg  Trust shall be entitled  to a  compensation  (the
            "Compensation") which equals


                                       10

            the  amount  of  the  purchase  price  under  the  Forward  Purchase
            Agreement  (as defined  below).  Bucyrus  herewith  irrevocably  and
            unconditionally   guarantees  within  the  meaning  of  a  guarantee
            pursuant to Section 311 para. 1 BGB vis-a-vis Hamburg Trust that the
            Company  will  fulfill its  obligations  under this  Section 7 as if
            Bucyrus were the primary  obligor.  The  guarantee set forth in this
            Section 7.2 is a continuing  guarantee and shall remain in force and
            in fact until the Company has  performed and  discharged  all of its
            respective obligations.

7.3         Execution of redemption  right. If any of the Assignment  Conditions
            set forth in (v) of Section  5.2 of the Forward  Purchase  Agreement
            turns out to be  incorrect  before the  Closing set forth in the SPA
            has been  completed,  the Company shall only exercise the redemption
            right  according  to its Articles of  Association  without the prior
            written  consent of Hamburg  Trust if and when RCI has not exercised
            its rights to request a transfer of the Class A Share  according  to
            Section 7.1.7 of the SPA up to the completion of such Closing.

8.          Financing of the Company; Pledges

8.1         Initial  Financing.  The  Company  shall be  initially  financed  by
            capital   contributions   (Stammeinlagen)  of  the  Shareholders  as
            described in lit. A of the Preamble.

8.2         Subsequent  Financing.   Hamburg  Trust  shall  not  be  obliged  to
            contribute any additional funds to the Company regardless whether as
            equity or debt or under any other instrument.  Bucyurs shall be free
            to decide on how to finance the Company.

8.3         Pledges.  Upon request by Bucyrus,  Hamburg Trust shall cooperate to
            the fullest extent  possible to pledge the Class A Share in relation
            to the  Acquisition  Financing or in case of any  refinancing of the
            Acquisition  Financing  provided,  however,  that any  liability  of
            Hamburg  Trust  under  such  pledge  shall be limited to the Class A
            Share.  In the event any  security  interest  created  hereunder  is
            enforced or affects the execution and completion of the transactions
            contemplated  under the Forward  Purchase  Agreement  (including the
            redemption  of the  Class A Share in lieu of its sale and  transfer)
            Bucyrus shall pay to Hamburg Trust the amount of the purchase  price
            under the Forward Purchase Agreement.

            of any nature whatsoever under or by reason of this Agreement.

18.12       Partial Invalidity.  In the case that one or more provisions of this
            Agreement shall be invalid or  unenforceable,  this shall not affect
            the  validity and  enforceability  of the other  provisions  of this
            Agreement. In such case the Shareholders agree to recognize and give
            effect to such valid and enforceable  provision or provisions  which
            reflect as closely as  possible  the  commercial  intention  of such
            invalid  or  unenforceable  provision  as  regards  subject  matter,
            amount,  time,  place and extent.  The same shall apply in the event
            that this Agreement contains any omissions (Vertragslucken).
