     wall, but the Director of Lands may, in granting his consent, impose
     reasonable conditions for safeguarding the structure of the bridge or wall,
     or the users thereof.

     and substantial repair.

12.  The Government may at any time enter upon any cutting, embankment or
     retaining wall on the said land which, by reason of its condition,
     injuriously affects or is likely to affect any Government land or bridge
     and execute such work thereon as may be reasonably necessary to prevent
     such injurious affection. The reasonable costs so incurred shall be a debt
     owing by the Corporation to the Government.

13.  The Corporation shall maintain in good and substantial repair fences, save
     and except the Border Fence, erected or to be erected on the said land and

     things, the use of which is common to the said land and to any adjoining
     land held by the Government.  In the absence of agreement on the sum the
     Government or the Corporation shall pay, this shall be determined in
     accordance with the Arbitration Ordinance (Cap. 341) by reference to 2
     arbitrators, one to be appointed by each party.

15.  The Government shall have the right to such facilities as it may reasonably
     require for police, immigration or customs purposes on railway premises,
     provided that nothing in this clause shall require the Corporation to carry

     Government.

16.  Any reference to the Government or the Corporation shall where the
     reference relates to any right to go onto any land or do anything thereon

            Guide to Determining the Loss of Revenue to the Employer

The following comprises a guide to contractors as to the method of calculating
any loss of revenue to the Employer.

Note:

1.  The figures used in the examples indicate the level of loss which might be
    caused by one hour of delay to rail traffic.

2.  If there has been a fare increase during the periods being considered for
    the purposes of calculation then due allowances will be made in the
    calculations.

3.  If the loss of revenue calculated in the way indicated below should be
    less than the actual refund to passengers, then the actual amount of
    refund shall be taken as the Employer's claim for loss of revenue.

A.      NORMAL DAILY SERVICES

        Normal daily services includes weekdays, Saturdays and Sundays other
        than when such days comprise the seven days before a General Holiday,
        that General Holiday and the seven days after the General Holiday. A
        General Holiday shall be a day as laid down by Notice in the Government
        Gazette.

        To calculate the loss, the aggregate of revenue earnings from rail
        traffic on the same day for the three previous weeks will be divided by
        three and the actual revenue on the day in question will be deducted
        from this.

        Example 1

        If the contractor caused delay to rail traffic on Tuesday, 15 June 1982,
        the following calculation will be carried out by the Employer:

A.   INTRODUCTION

     1.1  This Preamble to the Pricing Document describes and explains the
          various parts of the Pricing Document and their inter relationship.

     1.2  Notwithstanding Clause 1.3.2 of the General Conditions, the headings
          and sub-headings contained in the Pricing Schedule shall be taken into
          consideration in the interpretation and construction of such

B.   PRICING SCHEDULE

1.   General

     1.1  For payment purposes, the Works are divided into Cost Centres, each of
          which represents a major item or series of interrelated items
          associated with the Works. It is not the intent that item descriptions
          contained in any Cost Centre fully define the scope of work to be
          executed under each Cost Centre.

     1.2  Cost Centre A comprises the Preliminaries and General Requirements.

     1.3  Cost Centre H comprise Provisional Sums and Daywork. Expenditure
          against these Cost Centres, if any, will be subject to and in
          accordance with Clause 65 of the General Conditions in respect of
          Provisional Sums, Clause 15 of the Special Conditions in respect of
          Reuse Equipment and Clause 55 of the General Conditions in respect of
          Daywork. The Cost Centre Value for each of Cost Centre H will be
          revised to nil upon the issue of the Letter of Acceptance, in
          accordance with Clause 66.2 of the General Conditions.

     1.4  Cost Centres may be divided into Activity Bills and/or Parts
          describing elements of work, each of which has a price entered against
          it. The sum of all prices included in each Cost Centre shall represent
          the Cost Centre Value for that Cost Centre.

SIEMENS                                            Appendix 2 - Pricing Document

                1.5 Cost Centres B, C, D, E, F and G contain lump sum items. The
                    Cost Centre Values of such Cost Centres are not subject to
                    adjustment in respect of the actual quantities of work
                    executed by the Contractor, and represent the extent of the
                    Contractor's entitlement to receive payment in respect of
                    such Cost Centres subject only to the express provisions of
                    the Contract including without limitation, and where
                    appropriate, the prior exercise of any Option by the
                    Engineer in accordance with the Contract.

                1.6 Cost Centres C, D, E and F involve a significant amount of
                    procurement and fabrication which will be undertaken outside
                    of Hong Kong. Accordingly, interim payments against these
                    Cost Centres will be subject to the provision of Off-shore
                    Manufacturing Bonds as described in Paragraph F below.

                1.7 Any error in the Pricing Schedule or omission therefrom
                    shall not vitiate the Contract nor release the Contractor
                    from the execution of the whole or any part of the Works
                    according to the Employer's Drawings and the Specification
                    or from any of his obligations under the Contract.

     provided in the same currency as the Denominated Currency specified in the
     Pricing Summary in respect of the Cost Centre for which the bond is
     produced.

2.   Each Off-shore Manufacturing Bond in respect of Cost Centres C, D, E and F
     shall, in the first instance, be in sums equivalent to 50% of the relevant
     Cost Centre Value in respect of which it is produced and shall be provided
     by the Contractor to the Engineer at the time that any application for
     interim payment is made in respect of such Cost Centre, pursuant to Clause
     67 of the General Conditions.

3.   Each Off-shore Manufacturing Bond provided in respect of Cost Centres C, D,
     E and F shall be increased in value from 50% of the relevant Cost Centre
     Value to 95% of the Cost Centre Value when 50% of the Cost Centre Value of
     the relevant Cost Centre has been certified in favour of the Contractor
     pursuant to Clause 67 of the General Conditions. The said increase in value
     may be effected by the provision of a replacement Bond in respect of each
     Cost Centre, in identical terms to the original save in respect only of
     the amount of the Bond, duly executed by the same Bondsman. On receipt of
     any replacement Bond in satisfactory terms, the Employer shall release to
     the Contractor the Bond previously provided. In the event that the
     Contractor shall fail to provide a Bond in increased value as aforesaid,
     the Contractor shall not be entitled to receive any further payment in
     respect of the relevant Cost Centre.

4.   When the value of the goods manufactured off-shore, included in any of Cost
     Centres C, D, E and F delivered to the Site reaches 50% of the relevant
     Cost Centre Value, the Contractor shall notify the Engineer accordingly,
     and the Engineer shall inspect such items. Provided that:

     (a)  such goods appear to be in accordance with the requirements of the
          Contract; and

     (b)  the Engineer is satisfied that property in such items has vested in
          the Employer in accordance with Clause 61 of the General Conditions,

     the value of any Off-shore Manufacturing Bond provided by the Contractor in
     respect of the relevant Cost Centre may be reduced from 95% to 50% of the
     relevant Cost Centre Value. The said decrease in value may be effected by
     the provision of a replacement Bond in respect of each Cost Centre, in
     identical terms to the original save in respect only of the amount of the
     Bond, duly executed by the same Bondsman. On receipt of any replacement
     Bond in satisfactory terms, the Employer shall release to the Contractor
     the Bond previously provided.

5.   Any Off-shore Manufacturing Bond provided in respect of Cost Centres C, D,
     E and F shall be surrendered by the Employer when all of the goods
     manufactured off-shore and included in the Cost Centre in respect of which
     the Bond has been provided have been delivered to the Site and, following
     notification from the Contractor to the Engineer of the delivery of all
     such goods, the Engineer certifies

                     followed by a Percentage Adjustment item given to two
                     places of decimal. The price inserted against each such
                     item shall be calculated by applying the Percentage

                     Site to and from the location where daywork is to be
                     carried out shall be measured.

               1.2.2 Payment for labour employed on a daywork basis shall be
                     made in accordance with the rates listed in the Daywork

5.2.10     Status Monitoring

5.2.10-l   The Signalling Sub-system shall provide condition and status
           monitoring of all signalling equipment, and shall report equipment
           failure, status and condition to the OCC engineers Workstation.
           Failures shall include a loss of communication or function.

5.2.10.2   Self-test and lamp test facilities shall be provided on all
           Signalling Sub-system equipment.

5.2.10.3   The Signalling Sub-system shall provide distinctive audible and
           visual alarms to the operators at the OCC Workstations. The alarms
           shall be capable of being grouped as required (typically by type,
           priority, area etc.). The acknowledgement and clearing of alarms
           shall be configurable by LR operators. Facilities shall be provided
           to allow the alarms to be generated without sounding the audible
           alarm. As a minimum operator alarms shall be raised for the following
           events;

               a)   Wrong routing - alarm raised if an LRV deviates from its
                    predefined Route;

               b)   Point failure - alarm raised if Points fail or lose
                    detection;

               c)   Indicator failure - alarm raised if a trackside indicator
                    fails;

               d)   Load alarm - alarm raised if the load of successive LRVs
                    (number configured by operators) is above an operator
                    defined level for a particular Stop;

               e)   No service - alarm raised if no vehicle movement is detected
                    over a section of the LR network for given period of time
                    (defined by operators); and

               f)   On-board equipment failure.

5.2.10.4   During the migration phase the interface between the existing
           signalling system and new Signalling Sub-system OCC Workstations
           shall operate as follows:

               a)   When an LRV moves between systems (in either direction) the
                    Workstation of the system being exited shall display the LRV
                    identity at its last detection point. When the LRV has left
                    the area covered by the system being exited the LRV identity
                    shall continue to be displayed at its last detection point.
                    The next LRV to travel across the same boundary in the same
                    direction shall also have its LRV identity displayed at the
                    last detection point. This shall continue until 5 LRV
                    identities are displayed in order of arrival at the last
                    detection point;

               b)   Subsequent LRVs to travel across the same boundary in the
                    same direction shall be displayed with the earliest LRV
                    identity being removed from display. The operation of this
                    interface shall not cause audible or visual alarms to the
                    operators;

               c)   The system being entered shall only display the LRV identity
                    when it reaches the first detection point; and

               d)   During the migration phase no operator action shall be
                    required at the OCC for an LRV to transfer between the
                    existing signalling system and the new Signalling
                    Sub-system;

                                                                         [STAMP]

           information to be monitored from the OCC Workstation. As a minimum
           the LRV location shall be shown on a geographic display of the LR
           network to indicate that it is either at a Stop or between Stops.

5.2.10.9   The vehicle information to be displayed shall include but not be
           limited to:

               a)   LRV number;

               b)   Route number;

               c)   Run number;

               d)   Driver number;
