This document summarizes a presentation by Clean Marine AS on their exhaust gas cleaning system. Some key points: - Clean Marine AS is a pioneering company in exhaust gas cleaning systems (EGCS) with over 20 employees and USD 20 million invested in development. - They have a proven EGCS technology and a contract to install systems on two Samsung/AET shuttle tankers delivering in late 2014 and early 2015. - With new sulfur regulations coming into effect from 2015, EGCS presents a viable option for vessels to continue using less expensive high-sulfur fuel and avoid costly low-sulfur fuel.

3. With proven technology and the recent contract with
Samsung / AET we are well positioned for sales growth
• Contracts:
– MV Balder: EGCS installed 2012/2013 and is now fully certified
– Samsung / AET – 2 x 120k dwt. shuttle tankers to be delivered Q4 2014 + Q1 2015
• Main focus – bulk, tankers, Ro-Ro, PCTC, containers
• A growing agency network in Europe and Asia will facilitate sales & after service

5. The business case for installing an EGCS
Options for compliance with regulations:
1. Switch to distillate (MGO) – pay the extra fuel bill
2. Install EGCS – continue operation on HFO
3. Switch to other fuel types (LNG or LPG) – limited supply
Optimal choice depend on:
1. How much the vessel will be trading in ECA
2. The power (MW) and fuel consumption of the vessel
3. Assumed price difference between MGO and HFO
21 June 2013 5
Example:
10MW vessel trading in ECA and USD 300 fuel spread gives fuel cost = USD 3,4 mill./year
EGCS price: USD 2,6 mill + Installation cost USD 0,8 mill = USD 3,4 mill.

Guidelines, Regional/Local regulations (EU directive,
VGP US)
• Certification: Scheme A or Scheme B (monitoring)
• Monitoring:
– SO2/CO2 (97-98 % reduction required)
– pH (6,5 at 4m from outlet, 6 at outlet suggested by VGP)
– Turbidity (Diff In/Out 25 FNU)
– PAHphenantrene equiv. (Pending amount of water per MW)
