1. INTRODUCTION

1.1 IT WAS ANNOUNCED ON 12 MARCH 1999 THAT, SUBJECT TO THE FULFILMENT OF
CERTAIN CONDITIONS PRECEDENT, AGREEMENT IN PRINCIPLE HAD BEEN REACHED IN TERMS
OF WHICH THE INTERESTS OF TRANS HEX AND ODM ARE TO BE MERGED ("THE MERGER"),
WITH THE MERGED ENTITY COMPRISING 66,7% TRANS HEX AND 33,3% ODM, RESPECTIVELY
("THE GROUP").

1.2 DEUTSCHE MORGAN GRENFELL (SA) (PTY) LIMITED ("DMG") AND HSBC SIMPSON MCKIE
(PTY) LIMITED ("HSBC") ARE AUTHORISED TO ANNOUNCE THAT THE MERGER IS TO BE
ACHIEVED BY COMBINING THE INTERESTS OF TRANS HEX AND ODM UNDER TRANS HEX, WHICH
WILL BECOME THE NEW GROUP HOLDING COMPANY. ACCORDINGLY, TRANS HEX WILL PROPOSE
A SCHEME OF ARRANGEMENT ("THE SCHEME") IN TERMS OF SECTION 311 OF THE COMPANIES
ACT (ACT 61 OF 1973), AS AMENDED, BETWEEN ODM AND ITS SHAREHOLDERS OTHER THAN
TRANS HEX.

1.3 PURSUANT TO THE MERGER, IT IS PROPOSED THAT TRANS HEX WILL CHANGE ITS NAME
("THE CHANGE OF NAME") AND RECONSTITUTE ITS BOARD OF DIRECTORS, TO REFLECT THE
NEW IDENTITY OF THE MERGED GROUP, AND APPLY FOR A LISTING OF IT'S SHARES ON THE
NAMIBIAN STOCK EXCHANGE ("THE NSX").

1.4 IN ADDITION TO, BUT NOT CONDITIONAL ON, THE MERGER, IT IS PROPOSED THAT
TRANS HEX:

1.4.1 SUB-DIVIDES EACH ISSUED ORDINARY SHARE ("THE SUB-DIVISION"); AND
1.4.2 INCREASES ITS AUTHORISED SHARE CAPITAL.

2. RATIONALE FOR THE MERGER AND PROSPECTS FOR THE GROUP
2.1 RATIONALE FOR THE MERGER

THE MERGER COMBINES THE CORE COMPETENCIES OF TRANS HEX AND ODM TO CREATE A
SIGNIFICANT, INTERNATIONALLY RECOGNISED PRODUCER OF HIGH VALUE DIAMONDS, FROM
BOTH LAND AND MARINE RESOURCES, WITH EXCITING EXPLORATION POTENTIAL. THE GROUP
WILL THEREFORE SECURE THE FOLLOWING COMPETITIVE ADVANTAGES:

- DIVERSIFICATION OF PRODUCTION SOURCES THEREBY REDUCING OPERATIONAL RISK;
- ACCELERATION OF EXPLORATION TO INCREASE RESERVES;

- OPTIMISED UTILISATION OF GROUP CASH FLOWS TO ACCELERATE THE DEVELOPMENT OF
NEW DIAMOND MINING TECHNOLOGIES;

- INCREASED FREE FLOAT AND ENHANCED LIQUIDITY AND TRADABILITY OF THE ISSUED
SHARE CAPITAL;

- OPPORTUNITY TO REDUCE OVERHEADS AND RESTRUCTURE ASSETS AND OPERATIONS WITH
THE OBJECTIVE OF REDUCING COSTS;

- POOLING OF TRANS HEX AND ODM MANAGEMENT RESOURCES AND EXPERTISE RESULTING IN
THE CREATION OF A MANAGEMENT TEAM WHICH HAS A DIVERSE SKILLS BASE ACROSS THE
RANGE FROM BOTH LAND AND MARINE DIAMOND MINING, AND WHICH HAS THE ABILITY TO
ENSURE THAT THE GROUP'S ASSETS ARE DEVELOPED AND MANAGED TO THE MAXIMUM BENEFIT
OF ALL ITS SHAREHOLDERS;

- GREATER CRITICAL MASS WHICH WILL BETTER FACILITATE INTERNATIONALISATION,
ACCESS TO CAPITAL MARKETS AND ACCESS TO OTHER RESOURCES NECESSARY FOR EFFECTIVE
GROWTH;

- GREATER FINANCIAL STRENGTH WILL INCREASE ITS ABILITY TO COMPETE FOR NEW ORE
RESERVES, HUMAN RESOURCES AND CAPITAL;

- TRANS HEX HAS HISTORICALLY MARKETED ODM'S DIAMONDS. THE COMPLETE INTEGRATION
OF ODM'S PRODUCTION AND MARKETING FUNCTION WITH THAT OF TRANS HEX WILL GIVE THE
GROUP GREATER MARKET PRESENCE AND BETTER POSITION IT TO SUPPLY THE ENTIRE RANGE
OF ROUGH DIAMOND QUALITIES AND SIZES, WITH EMPHASIS ON THE HIGHER QUALITY
RANGES.
2.2 PROSPECTS FOR THE GROUP

THE DIRECTORS OF TRANS HEX AND ODM BELIEVE THAT THE PORTFOLIO OF ASSETS THAT
THEIR RESPECTIVE COMPANIES BRING TO THE MERGER PRESENTS A PLATFORM FROM WHICH
TO DEVELOP A STRONGER, GROWTH ORIENTED, INTERNATIONAL DIAMOND MINING,
DEVELOPMENT AND EXPLORATION COMPANY.

IN ORDER TO REALISE THESE OBJECTIVES, THE DIRECTORS RECOGNISE THAT IN THE SHORT
TERM, THEY MUST INCREASE THE PROFITABILITY, AND HENCE THE FREE CASH FLOWS, OF
EXISTING OPERATIONS. IN THE MEDIUM TO LONGER TERM, THE DIRECTORS BELIEVE THAT
THE GROUP MUST SEEK TO IDENTIFY AND BRING INTO PRODUCTION, THROUGH ACQUISITION
AND EXPLORATION, HIGH QUALITY, LOW COST AND LONG LIFE DIAMOND MINING ASSETS.
SHORT-TERM PROFITABILITY WILL CONTINUE TO BE ENHANCED BY THE ADOPTION OF MORE
EFFECTIVE TECHNIQUES AND WORK PRACTICES, AND THE REDUCTION OF OVERHEADS.
INITIATIVES ARE ALREADY UNDERWAY TO INTRODUCE NEW TECHNOLOGY INTO THE MARINE
MINING DIVISIONS, AS A RESULT OF WHICH MARINE MINING OPERATIONS WILL BECOME
MORE EFFICIENT IN TERMS OF DIAMONDIFEROUS GRAVEL RECOVERY FROM THE SEA BED.
MORE EFFICIENT MARINE MINING WILL ALSO HAVE A SIGNIFICANT OPERATIONAL COST
SAVING AND WILL ULTIMATELY ALLOW MINING OF SOME LOWER GRADE ORES, THEREBY
EXPANDING THE LIFE OF ORE RESERVES.

THE GROUP STRIVES TO EXTEND ITS PROVEN DIAMOND ORE RESERVES IN SOUTHERN AFRICA
TO MORE THAN 20 YEARS, WITH A TOTAL GROUP PRODUCTION OF MORE THAN 1 MILLION
CARATS AND/OR SALES OF US$250 MILLION PER YEAR.  THIS WILL BE ACHIEVED THROUGH
CONTINUATION OF THE GROUP'S AGGRESSIVE EXPLORATION POLICY, AS WELL AS POSSIBLE
MERGER AND ACQUISITION OPPORTUNITIES.

AFTER THE MERGER, THE BOARDS OF DIRECTORS OF TRANS HEX AND ODM ARE OF THE VIEW
THAT THE GROUP WILL BE IN A BETTER POSITION TO TAKE ADVANTAGE OF INTERNATIONAL
DIAMOND MINING OPPORTUNITIES. THIS ABILITY MAY BE FURTHER ENHANCED BY A
POSSIBLE LISTING ON AN INTERNATIONAL STOCK EXCHANGE, THE POSSIBILITY OF WHICH
WILL BE INVESTIGATED IN DUE COURSE.  SUCH A LISTING WOULD PROVIDE THE GROUP
WITH ACCESS TO INTERNATIONAL EQUITY MARKETS FOR THE RAISING OF FINANCE FOR
EXPANSION OF ITS ACTIVITIES IN SOUTH AFRICA, NAMIBIA AND FURTHER AFIELD AND MAY
ASSIST IN ENHANCING SHAREHOLDER VALUE, A PRIMARY OBJECTIVE OF THE GROUP.
3. TERMS OF THE SCHEME

3.1 SUBJECT TO THE SCHEME BEING IMPLEMENTED, ODM WILL BECOME A WHOLLY OWNED
SUBSIDIARY OF TRANS HEX WITH EFFECT FROM 1 APRIL 1999. ACCORDINGLY, THE
LISTINGS OF ODM'S SHARES ON THE JOHANNESBURG STOCK EXCHANGE ("THE JSE") AND THE
NSX WILL BE TERMINATED.

3.2 THE SCHEME INVOLVES THE ACQUISITION BY TRANS HEX OF ALL THE ODM SHARES HELD
BY EACH ODM SHAREHOLDER, OTHER THAN TRANS HEX ("SCHEME PARTICIPANTS"), IN
RETURN FOR WHICH EACH SCHEME PARTICIPANT WILL RECEIVE THE SCHEME CONSIDERATION,
NAMELY 17,19 TRANS HEX SHARES (OR 68,76 TRANS HEX SHARES AFTER THE SUB-DIVISION
DETAILED IN PARAGRAPH 6.1 BELOW) ("CONSIDERATION SHARES"), FOR EVERY 100 ODM
SHARES HELD ON THE RECORD DATE, BEING FRIDAY, 25 JUNE 1999.

3.3 FRACTIONAL ENTITLEMENTS TO CONSIDERATION SHARES DUE TO A SCHEME PARTICIPANT
WILL NOT BE ALLOCATED BUT WILL BE AGGREGATED AND SOLD IN THE MARKET FOR THE
BENEFIT OF THE SCHEME PARTICIPANT CONCERNED.
4. PROPOSED CHANGE OF NAME

THE DIRECTORS OF TRANS HEX HAVE RESOLVED THAT, SUBJECT TO THE APPROVAL OF TRANS
HEX SHAREHOLDERS AND THE MERGER BECOMING UNCONDITIONAL, THE NAME OF TRANS HEX
WILL BE CHANGED TO "TRANS OCEAN DIAMOND MINING LIMITED" ("TRANS OCEAN"), TO
CREATE A NEW IDENTITY FOR THE GROUP. THE GROUP WILL TRADE ON THE JSE UNDER THE
ABBREVIATED NAME "TODIAM" IN THE MINING RESOURCES - "DIAMONDS" SECTOR OF THE
JSE LISTS. THE CHANGE OF NAME IS EXPECTED TO BECOME EFFECTIVE ON MONDAY, 28TH
JUNE 1999, BEING THE OPERATIVE DATE OF THE SCHEME.

TRANS HEX TO FUND FUTURE ACQUISITIONS, THE DIRECTORS OF TRANS HEX PROPOSE TO
