Exhibit (c)(4) Project Kernel - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- Discussion Materials February 29, 2000 ================================================================================ MORGAN STANLEY DEAN WITTER - -------------------------------------------------------------------------------- Project Kernel - -------------------------------------------------------------------------------- Valuation Analysis - -------------------------------------------------------------------------------- Discounted Cash Flow Analysis ================================================================================ o A Discounted Cash Flow ("DCF") analysis of Kernel has been undertaken o Key source data is derived from public sources: - MSDW research estimates for 2000 and 2001 - forward oil and gas prices and differentials based on historical Kernel data and MSDW Research estimates - these assumptions are summarised overleaf, and given in more detail in Appendix B. o The DCF valuation is based on cash flows for the period 1999-2010, with a terminal value calculated using an exit EBITDA multiple of 6.0x to 7.5x o A discount rate of 9% - 10%, based on the weighted average cost of capital of comparable companies to Kernel, has been used o The resulting DCF equity value is in the range $4.1bn to $5.2Bn (Fully diluted equity value of 100% of Kernel), equivalent to $43 - $54 per share, a range containing the current share price o The valuation is particularly sensitive to changes in natural gas prices: a 10% reduction in gas prices causes a 16% reduction in DCF aggregate value o Other key assumptions include: - Cash costs of $3.40/bbl based on three year historical averages - Finding and development costs of $6.00 - Success rate of approximately 60% - Capital opportunities to cash flow in years 2000 to 2007 MORGAN STANLEY DEAN WITTER 2 -
