<div align="justify" style="font-size: 10pt; margin-top: 20pt"><b>Note I. </b><b><i>Derivative financial instruments</i></b>
</div>
<div align="justify" style="font-size: 10pt; margin-top: 10pt">        The Company uses derivative financial contracts to manage exposures to commodity price and
interest rate fluctuations. Commodity hedges are used to (i) reduce the effect of the volatility of
price changes on the oil and natural gas the Company produces and sells, (ii) support the Company’s
capital budget and expenditure plans and (iii) support the economics associated with acquisitions.
Interest rate hedges are used to mitigate the cash flow risk associated with rising interest rates.
The Company does not enter into derivative financial instruments for speculative or trading
purposes. The Company also may enter into physical delivery contracts to effectively provide
commodity price hedges. Because these contracts are not expected to be net cash settled, they are
considered to be normal sales contracts and not derivatives. Therefore, these contracts are not
recorded in the Company’s consolidated financial statements.
</div>
<div align="justify" style="font-size: 10pt; margin-top: 10pt">        Currently, the Company does not designate its derivative instruments to qualify for hedge
accounting. Accordingly, the Company reflects changes in the fair value of its derivative
instruments in its statements of operations as they occur. All of the Company’s remaining hedges
that historically qualified for hedge accounting or were dedesignated from hedge accounting were
settled in 2008.
</div>
<div align="justify" style="font-size: 10pt; margin-top: 10pt">        During 2007, the Company determined that all of its natural gas commodity contracts no longer
qualified as hedges (referred to as “dedesignated cash flow hedges”). The Company discontinued
hedge accounting from then forward for all derivative contracts.
