12. twAAA twBB twAA Business Profile Comparison Market Position –Revenue trend reflects the widening gap

13. twAAA twBB twAA Business Profile Comparison Low Cost Position & Technology Leadership –Scale economies are important due to a higher percentage of material costs for new production technology –AUO has better scale economies and the first mover advantage in new technology –CMO has better integration into in-house component production, but slower in ramping advanced facilities, including its 5G and 5.5G fabs –CPT operates 3G and 4.5G fabs, resulting in less favorable cost structure –QDI currently operates one 3.5G fab and one 5G fab and will commission its first 6G fab in 1H06 –HannStar was the slowest to ramp 5G technology. Its cost position could deteriorate without a clear 6G plan

14. twAAA twBB twAA Business Profile Comparison Low Cost Position & Technology Leadership –Korean players still have advantage in production technology, but AUO and CMO are catching up

15. twAAA twBB twAA Business Profile Comparison Product and application mix –All are single product companies, representing high product concentration risk –AUO has a better product and application mix because of its good position in the small- to mid-size TFT-LCD sector –CMO occupies good position in the LCD TV segment: 20% global market share and 38% of its revenue in 1H05 –CPT, QDI, and HannStar all continue to focus on notebook PCs and PC monitors –CPTs legacy CRT business and PDP investment are not considered as meaningful product diversification

16. twAAA twBB twAA Business Profile Comparison Product and application mix –AUO has a good position in the small-size panel segment –AUO can better use its 3.5G capacity, which is not cost effective for large-area panel production

17. twAAA twBB twAA Financial Profile Comparison Conclusion

18. twAAA twBB twAA Financial Profile Comparison Profitability –AUO and CMO enhanced their leading profitability positions relative to CPT, QDI and HannStar, reflecting their stronger business profiles

19. twAAA twBB twAA Financial Profile Comparison Profitability –The gap between industry leaders and laggards expanded during the recent business cycle –Margin gap widens during down cycles as a result of differences in production technology and product mix

25. twAAA twBB twAA Financial Profile Comparison Capital Structure & Financial Flexibility –Higher leverage in 1H05 due to lower profit and high capex –Total debt/EBITDA improved in 1H05, compared with 2001 –The banking sector's appetite for new exposure to the industry becomes more limited

26. twAAA twBB twAA Conclusion Diverging credit quality among Taiwan's panel makers Reasons behind: better scale economies, product diversification and technology lead to better profitability and cash flows This in turn expands the gap between leaders and laggards because of leaders' more aggressive expenditures AUO has a clear-cut leading position among Taiwan's panel makers in terms of credit quality CMO follows closely, but needs to enhance its execution and product strategy M&A may not happen soon because of continued access to loan and equity markets Local banks' decreasing appetite has a negative implication, particularly for smaller players
