Exhibit I

- Litigation

Kenneth Schuck Trucking has claimed either directly or through a collection
agency that it is due from SRP $29,138.00 from 1996 to 1997 primarily for
unauthorized detention time relating to trucking charges. SRP believes that
these charges are invalid. In some cases, the invoices for which claims were
asserted had been paid, and SRP has so informed the claimant. SRP has not
established any reserve for this claim.

MCI WorldCom has invoiced SRP for approximately $10,800, which SRP disputes. The
charges span a period from the beginning of the contract (in excess of two (2)
years) to the current period. Repeated documented attempts via phone calls,
e-mails, and faxes have been made to try to resolve this issue with MCI
WorldCom, without success. Periodic payments have been made, but the account
remains past due according to the MCI WorldCom records. Considering the
situation of MCI WorldCom a full resolution may take time. The disputed amount
has not been reserved.
