               proposed disclosure by LGL is in any form of public statement,
               release or announcement, such as a prospectus, Rio Tinto's
               approval may be given or withheld in its absolute discretion.

          (ii) LGL may also disclose a Report to:

               (A)  any employee, agent or contractor; and

               (B)  any Related Corporation, but only so long as one or more
                    parties have not exercised Effective Control in relation to

          announcements or disclosures as to this Agreement, or otherwise in
          relation to the subject matter of this Agreement, without the prior

          opportunity to comment on the form and content of the proposed
          announcement.

          assignments or other documents which Rio Tinto may deem necessary for
          the registration or protection of any of its interests in the

          following termination of this Agreement, Rio Tinto will meet LGL's
          reasonable costs with respect to the assistance required pursuant to
          this Clause 10.1.

     If and to the extent that Rio Tinto creates any Intellectual Property as a

     Intellectual Property by LGL, and its Related Corporations from time to
     time, for their own purposes.

11.  RELATIONSHIP OF PARTIES

11.1 INDEPENDENT CONTRACTOR

     In providing the Services to LGL under this Agreement, Rio Tinto is acting
     in the capacity of independent contractor. This Agreement does not
     constitute or create an employer and employee relationship, a partnership
     of any kind, or an association or trust between the Parties.


                                                                         Page 13

     warranties, terms, conditions and representations, whether express,
     implied, statutory or otherwise relating in any way to the subject matter
     of this Agreement or to this Agreement generally, are excluded. Where any
     Law implies into this Agreement any term, and that law limits or prohibits
     provisions in a contract excluding or modifying the application of or
     exclusion of liability under that term, the term is included in this
     Agreement only to the extent required by Law.

13.  LIMITATION OF LIABILITY

          indemnity, damages or otherwise) in connection with the Services
          (whether for any breach of this Agreement, negligence or otherwise),
          unless a claim is made in writing by LGL within six months after the
          circumstances giving rise to the claim first became known by LGL or
          could, with reasonable diligence, have become known by LGL. Any claim
          must set forth in reasonable detail the nature of the claim and the
          amount sought to the extent the amount can reasonably be determined.

     (b)  EXCLUSION OF INDIRECT OR CONSEQUENTIAL LOSS

          In no circumstances will Rio Tinto be liable to LGL to make any
          payment (whether by way of indemnity, damages or otherwise) in
          connection with the Services (whether for any breach of this
          Agreement, negligence or otherwise) in respect of any indirect or
          consequential loss or damage (including loss of profit or loss of
          production), howsoever arising.

     (c)  LIABILITY CAP FOR PAYMENTS

          Rio Tinto is not liable to LGL to make any payment (whether by way of
          indemnity, damages or otherwise) in connection with the Services
          (whether for any breach of this Agreement, negligence or otherwise) to
          the extent that such payment, when aggregated


                                                                         Page 14

          with all other such payments in respect of the Services, exceeds the
          aggregate of all Service Fees paid by LGL under this Agreement for the
          performance of the Services. In lieu of Rio Tinto making any such
          payment, LGL may require Rio Tinto to re-perform the relevant
          Services, subject to Rio Tinto's prior agreement (such agreement not
          to be unreasonably withheld).

     (d)  OTHER LIMITATIONS AND EXCLUSIONS

          Rio Tinto is not liable to LGL for any loss that LGL suffers in
          connection with the Services, to the extent that the loss arises from
          any act or omission of LGL,

14.  TERMINATION

14.1 LGL MAY TERMINATE

     LGL may terminate this Agreement at any time upon giving thirty (30) days'
     prior written notice to Rio Tinto.

     Rio Tinto or LGL may terminate this Agreement at any time by written notice
     to the other, if, during the Term, one or more parties exercise Effective
     Control in relation to LGL. This right of termination will arise regardless
     of whether the exercise of Effective Control follows or arises as a
     consequence of a corporate reorganisation, capital restructure, or
     otherwise.

14.3 EACH PARTY MAY TERMINATE

     Without limiting Clauses 14.1 and 14.2,

     (a)  each of Rio Tinto and LGL may terminate this Agreement immediately if
          the other becomes insolvent; and

     (b)  each of Rio Tinto and LGL may terminate this Agreement immediately
          upon giving written notice to the other if that other Party is in
          default of this Agreement and such Party fails to remedy the default
          within thirty (30) days after written notice from the first Party
          requiring the remedy of the default.

15.  CONSEQUENCES OF TERMINATION

     that date.

     Clauses 1, 9, 10, 11, 13, 16, 24, 30 and 33 of this Agreement and the
     relevant provisions of this Clause 15 will continue to apply after
     termination of this Agreement.

16.  INDEMNITY

     LGL indemnifies Rio Tinto, and holds Rio Tinto harmless, against and in
     respect of any claim, loss, damage, suit, liability, cost, injury or

               the Notice is sent or at a time later than 4:00 pm (local time),
               it will be taken to have been duly given or made at the
               commencement of business on the next business day in that place.

19.  ENTIRE AGREEMENT

     This Agreement, including the provisions of any statute or agreement
     incorporated by reference, constitutes the entire agreement between the
     Parties with respect to its subject matter. It sets out the only conduct
     relied on by the Parties and supersedes all prior agreements and
     understandings between the Parties in connection with its subject matter.

20.  AMENDMENT

     No amendment, variation or modification of this Agreement is valid or
     binding unless made in writing and duly executed by or on behalf of all
     Parties.

21.  ASSIGNMENT

     (a)  Each of TRPL and RTS will have the right to arrange for any of its
          obligations under this Agreement to be performed by others on its
          behalf, and it shall be free to assign its rights and obligations
          under this Agreement to any other member of the Rio Tinto Group.
          However, this right of assignment will not in any way undermine the
          express rights of LGL set out in Clauses 4.5 and 5.5.

     (b)  The rights and obligations of LGL under this Agreement cannot be
          assigned, encumbered or otherwise dealt with except with the prior
          written consent of Rio Tinto, which consent may not be unreasonably
          withheld.

22.  FORCE MAJEURE

     (a)  If:

          (i)  in the reasonable opinion of the Rio Tinto Representative,
               performance of this Agreement or any obligation hereunder by Rio
               Tinto is prevented, restricted or interfered with as a result of
               Force Majeure; or

          (ii) in the reasonable opinion of the LGL Representative, performance
               of this Agreement or any obligation hereunder by LGL is
               prevented, restricted or interfered with as a result of Force
               Majeure,

          the Party so affected upon prompt notice to the other will be excused
          from such performance to the extent of such prevention, restriction or
          interference, and for the period that the Force Majeure event
          continues. This Clause 22 will not apply in respect of any obligation
          to pay money that is due and payable.

     (b)  The Party so affected must use its best endeavours to avoid or remove
          such causes of non-performance and must continue performance hereunder
          with the utmost dispatch as soon as


                                                                         Page 17

<PAGE>

Technical and Procurement Services Agreement              Allens Arthur Robinson

          such causes are removed, provided that nothing in this Clause 22 may
          be construed as requiring the affected Party to settle any industrial
          dispute on terms which it considers disadvantageous.

     Consideration) to cost, expense or other similar amount (COST), is a
     reference to that Cost exclusive of GST.

23.6 GST OBLIGATIONS TO SURVIVE TERMINATION

     This Clause 23 will continue to apply after expiration or termination of
     this Agreement.

25.  NOMINATED REPRESENTATIVES

     Each of TRPL, RTS and LGL must nominate a person to be its primary
     representative for the purposes of this Agreement. These nominated
     representatives will be the initial and primary points of contact between
     TRPL or RTS on the one hand, and LGL on the other, in connection with any

26.  FURTHER ASSURANCES

     Each Party agrees to do all things and execute all deeds, instruments,
     transfers or other documents as may be necessary or desirable to give full
     effect to the provisions of this Agreement and the transactions
     contemplated by it.

27.  NO MERGER

     The rights and obligations of the Parties will not merge on the completion
     of any transaction contemplated by this Agreement. They will survive the
     execution and delivery of any assignment or other document entered into for
     the purpose of implementing any such transaction.

28.  NO WAIVER

     No failure to exercise nor any delay in exercising any right, power or
     remedy by a Party operates as a waiver. A single or partial exercise of any
     right, power or remedy does not preclude any other or further exercise of

     that provision in any other jurisdiction.

30.  GOVERNING LAW AND JURISDICTION

SCHEDULE 4

PROCUREMENT SERVICES

Once the Management Agreement is terminated, LGL would cease to be part of the
Rio Tinto Group for the purposes of the Rio Tinto Group procurement contracts.
Rio Tinto Procurement (RTP) will provide assistance to LGL as detailed below.
This assistance will not require RTP staff to travel to site unless expressly
agreed. Any disbursements incurred at the request of LGL will be to the account
of LGL.

<TABLE>
<S>               <C>
Functional        RTP will support LGL in building up its internal procurement
Review Process    capability. RTP will conduct a Functional Review Process which
                  would generate a detailed procurement improvement plan,
                  drawing on RTP's IP.

                  It is anticipated that this will be completed by the end of
                  Q1, 2006.

Explosives and    RTP will leverage its intellectual property and in-house
Accessories       skills to produce a market report covering explosives (and
                  accessories) in Australia, to assist LGL in establishing
                  LGL-specific supply arrangements for explosives and
                  accessories. The report would include coverage of RTP's view
                  of industry supply/demand balance, cost structures and supply
                  chain issues. However, the report will not include pricing.

                  The report will be completed by December 15.

Barges and Lime   RTP will conduct an opportunity assessment for supply from
supply ex-China   China of barges and lime. RTP will document the opportunity
                  assessment in a report for LGL. The opportunity assessment
                  would include identification of potential suppliers, review of
                  strengths and weaknesses, manufacturing capability, supply
                  chain issues and regulatory requirements in China. RTP's
                  Market Development staff will provide fortnightly verbal
                  updates on progress. The opportunity assessment will be
                  completed by production of a written report prepared by
                  December 15.

OTR Tyres         RTP will continue to include LGL in the Rio Tinto Group
                  process for the management of OTR tyres through the CTD and
                  Tyre Management Committee (TMC) until 31 December 2006, in
                  accordance with the terms of the letter agreement between the
                  Parties dated 15 September 2005.

HME               If LGL decided (e.g. to the stage of capital approval) to make
                  a major fleet replacement in 2006 or 2007, RTP would make
                  available designated RTP personnel during 2006 to assist LGL's
                  representatives to approach the HME manufacturers to establish
                  an LGL specific contract for the acquisition.

                  RTP's support would include access to RTP's total cost of
                  ownership and continuous improvement models as well as
                  negotiation preparation and support.

                  RTP's support would not include: access to the RTP personnel
                  involved in negotiating or managing the Rio Tinto Group's
                  relationship with the particular supplier(s); participation in
                  the Core Technologies Directorate; access to pricing or other

                  RTP's plans for any relet of contracts with HME manufacturers
                  / suppliers and associated negotiation strategies.

                  Such assistance would conclude with the execution of the fleet
                  replacement contract, or at the end of 2006 at the latest, and
                  would be limited to the equivalent of 160 man hours in total.

Shipping &        RTP will complete work currently in progress whereby LGL will
Logistics         directly contract shipping services (previously undertaken by
                  its freight forwarder), and renew international freight
                  forwarding (IFF) contractual arrangements. The shipping
                  contract is expected to be completed in September 2005, whilst
                  the IFF contract is anticipated to be completed by the end of
                  October 2005. The estimated cost of this work is A$78,600 and
                  is based on a daily rate of A$720 in respect of each of the
                  individuals involved.

                  RTP staff will "be made available to assist LGL in the
                  implementation of these contracts. The major areas of
