million senior secured credit agreement, consisting of a three-year revolving
credit facility and a five-year term loan; a $300 million offering of senior
secured notes due in 2009; and a $40 million supplemental letter of credit
facility.

     FMC intends to use borrowings under the new credit agreement and net

upcoming debt maturities, including its $99.5 million of 7.125 percent
Medium-Term Notes due November 2002 and $160.5 million of 6.375 percent
Debentures due September 2003; (ii) repay all borrowings under and terminate its
existing revolving credit facility and cancel its existing accounts receivable
securitization facility; (iii) replace with cash collateral certain standby
letters of credit and surety bonds that presently secure environmental
commitments to governmental agencies and certain other obligations and also cash
collateralize its reimbursement obligations with respect to letters of credit
that support outstanding floating rate industrial development bonds; and (iv)
pay fees and expenses.

     FMC is making this statement to be consistent with the Securities and
Exchange Commission's "fair disclosure" guidelines in advance of presentations
to investors. Concurrently with this release, the Company has filed a current
report on Form 8-K to disclose certain corporate and other information it will
provide to prospective investors in connection with the refinancing. Additional
