15. 14 Revenue-SDSL & Cisco Systems Korea Link’s (or the ‘Company”) sales revenue of Won 22,130 million for the 1H of 2000 represented 65% increase over the sales for the corresponding period in 1999 primarily due to 1) increased appetite for the Company’s products such as switches and routers in the market driven by the explosive industry growth, 2) new revenues from the sales of high speed internet access solutions such as SDSL, the Company’s own variant of a high-speed DSL products and BWLL, together accounted for 23.4% of total revenue. As a result, revenue dependency on 3Com products of the Company has lessened (to 51% versus 60% for the corresponding period) and the trend will continue for the remaining year as 1)the slice for SDSL and BWLL-related will become bigger and 2)Cisco product will gain a significant portion as the Company signed an SMB(small&medium sized Business)distribution in June. On the other hand, project revenues decreased from KRW2,746 million to 1,883 million because of slowdown in the 2 nd half of 1999. (KRW mil) 13,399 22,130 256

16. 15 Cost of Sales & Gross Profit Cost of sales went down to 78.4% of total revenue in the 1H of 2000 from 83.7% in the corresponding period primarily due to 1) the sales from SDSL products which are selling at much higher margin than other products and 2)an increase in the volume of supply purchases by the Company from the vendors. The Company expects the cost of sales continue to decrease as the sales of SDSL products and ESL (electronic shelf labeling system) start to generate higher revenues in the 2H of 2000. As a result, Company’s gross profit margin increased from 16.3% for the 1H 1999 to 21.6% for the corresponding period in 2000. (KRW mil)

17. 16 SG&A Expenses & Operating Income Operating income increased by 180% from Won 1,176 million to Won 3,290 million in the 1H of 2000. Half to half growth in operating income surpassed the corresponding period’s gross profit growth as a consequence of smaller increase in SG&A expenses even factoring 1) an increase in employees from 55 at June 30, 1999 to 90 at June 30,2000 and a 20% salary increase given to employees and 2) an increase in advertising expenses by 111% and 3)an increase in misc. fees and commissions into the growth of SG&A expenses. As the Company has made no significant tangible and intangible asset investments other than office equipment including computers and furniture, depreciation expenses only accounted for 0.1% of total revenue. (KRW mil)

18. 17 Net Non-Operating Income Non operating income decreased by 12% over the period due to 1) decreased foreign exchange translation gain resulted from more stable US$/KRW exchange rates and 2)decreased subsidy income consisting of cash rebates provided by 3Com as a result of approximately 62% of 3Com sales realized in the 2Qtr.(in which case, the cash rebate to be recorded in the 3Qtr.) Non operating expenses decreased by 56% primarily due to reduction in interest bearing debts and the appreciation of the Won relative to the US dollar.. (KRW mil)

19. 18 Debt Profile The Company’s interest bearing debt decreased by 39%, among which foreign currency (100% US$) denominated debt accounted for 75.4%. New cash proceeds from the IPO in Dec. 99 and paying down of over 39% of interest bearing debt during the period effectively lowered the liability to equity to 94% and debt to capitalization ratio* to 18% as at 30 June, 2000.
