9M and Q3 2012 Results Highlights

Driven by overall positive business sentiments in H1 2012 and GalaxyTM–

related pentration and usage, revenues rose 13% to US$49.6m and net

profit increased 35% to US$16.8m in 9M 2012

Q3 2012 revenue and net profit declined 26% and 41% to US$11.7m and

US$2.5m respectively due to following factors:

Increased rough diamond prices and short term price erosion of polished diamonds resulted in lower profitability for diamond manufacturers

Limited liquidity and working capital credit lines available to India manufacturers affected capital equipment investment

Various market uncertainties related to global macroeconomic conditions

Total recurring revenue grew 20% to over a third of group revenues in Q3 2012

New Products Update

GalaxyTM Family Rollout

Demand for GalaxyTM family of products remains strong in all major industry centres

From just over 20 at year end 2010, the Group more than doubled the installed base in 2011 to well over 50 systems

As of 30 September 2012, the Group has just under 90 systems deployed worldwide

GalaxyTM HD (High Definition) and XL (Extra Large) systems were shipped to the Israeli, Indian and Belgium service centres in late 2011 and early 2012 to broaden the service offerings to customers

An enhanced GalaxyTM system with microscope quality to detect even very small inclusions will be available in Sarin’s service centres in mid 2013

Adoption by Major Customers

15

BHP Billiton adopted GalaxyTM scanning technology to

map rough diamonds for sale in spot market auctions in

March 2010, followed by Blue Star (Arjav) of India in June

2011

Tiffany’s manufacturing arm, Laurelton, has adopted

GalaxyTM scanning technology to optimise their diamond

planning process

The ongoing adoption by major diamond miners, manufacturers and rough dealers is proof of GalaxyTM’s value proposition in facilitating the sale and manufacturing of rough diamonds

15

SolarisTM 100 – Small Stone Inclusion System

In October 2010, Sarin launched SolarisTM, the GalaxyTM equivalent for small stones (rough diamonds of under 2.5 carats)

This product helps diamond manufacturers achieve attractive returns on small-sized rough diamonds that typically yield lower margins

Provides exceptional scanning accuracy even to VVS levels

Group benefited from significant deliveries of SolarisTM systems in H1 2012

DiaMensionTM HD / InstructorTM / DiaMarkTM HD

DiaMensionTM HD

High-end product for proportion measurement and symmetry

grading of polished diamonds qualified by GIA and AGS

Symmetry grading new business opportunity as previously only

done manually

The InstructorTM software product For the ongoing quality control of the actual polishing process

as the polished diamond is faceted

Unique capability of providing instructions on necessary

corrective actions and/or possible asymmetric enhancements

Almost untapped market potential as the product targets a need

which, until its launch, had not been automated

Sales of both products are expected to continue to drive the growth

of Group’s polished diamond grading product line

Sarin-LightTM

With increasing demand for prettier diamonds, Light Performance parameters (brilliance, fire, scintillation/sparkle and symmetry) are becoming accepted as understandable consumer-oriented criteria

In December 2010, Sarin acquired the Light Performance Technology (LPT), a system that enables the automatic, independent and accurate measurement of a polished diamond’s appearance

The Group expects interest in LPT from the virtually all players in the diamond industry, including manufacturers, wholesalers, gem labs and retail chains

Sarin-LightTM was launched in trade shows in the US and Hong Kong to very positive response; Sarin is working to conclude commercial agreements with major industry players; initial ones hopefully by year’s end.

Similar to business model for GalaxyTM/SolarisTM, the business model adopted for Sarin-LightTM will add to recurring revenue.

Sarin-LightTM Imagery

Sarin-LoupeTM

An imaging system that captures a polished diamond, including its

internal features, in simulated three dimensions

Enables buyers to view it, as if with a traditional loupe, from a multitude

of angles and at varying magnifications, without having the polished

diamond physically in hand

Expected to significantly simplify the buying process of polished

diamonds by reducing costs and time involved for both buyers and

sellers

Target for commercial launch in 2013

Prospects

Prospects

While economic challenges prevail in Europe, some signs of improving economic conditions are emerging in markets such as China and the US.

The recent decline in rough diamond prices and renewed buying of polished diamonds by wholesalers and traders ahead of the year end holiday season have resulted in higher diamond manufacturing activities

in India.

GalaxyTM and SolarisTM inclusion mapping enhances demand for Sarin’s other products and contributes to the consolidation of the Group’s leading market share for manufacturing products

New service centres in additional diamond manufacturing centres and additional deliveries of GalaxyTM family systems will boost Sarin’s recurring revenue base

New products such as Sarin-LightTM, Sarin-LoupeTM and similar services (e.g., DAS) address the wholesale and retail trade of polished diamonds – a significant new market segment that is expected to add to the Group’s recurring revenue base

23

Deliveries of GalaxyTM family systems for rough diamond inclusion scanning and mapping to customers

Development of inclusion mapping system for polished diamonds (in research phase)

Launch of the Sarin-LightTM (LPT) and Sarin-LoupeTM

Expand Sarin’s potential markets to the mining and retail segments of the diamond industry

Broaden the Group’s revenue base into polished diamonds trade

Increase the recurrent portion of the revenue stream
