Notes Used as Qualified Replacement Property:

Prospective investors seeking to treat the Notes as "qualified replacement property" for purposes of Section 1042 of the Internal Revenue Code of 1986, as amended, should be aware that Section 1042 requires the issuer to meet certain requirements in order for the Notes to constitute qualified replacement property. In general, qualified replacement property is a security issued by a domestic

operating corporation that did not, for the taxable year preceding the taxable year in which such security was purchased, have "passive investment income" in excess of 25 percent of the gross receipts of such corporation for such preceding taxable year. For purposes of this passive income test, where the issuing corporation is in control of one or more corporations, all such corporations are treated as one corporation for the purposes of computing the amount of passive investment income for purposes of Section 1042.

We believe that less than 25 percent of our affiliated group's gross receipts is passive investment income for the taxable year ended December 31, 2003. In making this determination, we have made certain assumptions and used procedures which we believe are reasonable.

We cannot give any assurance as to whether we will continue to meet the passive income test. It is, in addition, possible that the IRS may disagree with the manner in which we have calculated our affiliated group's gross receipts (including the characterization thereof) and passive investment income and the conclusions reached herein. Prospective purchasers of the Notes should consult with their own tax advisors with respect to these and other tax matters relating to the Notes.

The Notes are a new issue of securities with no established trading market. No assurance can be given as to whether a trading market for the Notes will develop or as to the liquidity of a trading market for the Notes. The availability and liquidity of a trading market for the Notes will also be affected by the degree to which purchasers treat the Notes as qualified replacement property.
