                                   WITNESSETH:

         WHEREAS, the parties to the Credit Agreement have agreed to amend the
Credit Agreement and to waive certain provisions thereof for a limited period as
provided for herein.

         NOW, THEREFORE, the parties hereto agree as follows:

         SECTION 1. DEFINITIONS; REFERENCES. Unless otherwise specifically
defined herein, each term used herein that is defined in the Credit Agreement
shall have the meaning assigned to such term in the Credit Agreement. Each
reference to "hereof", "hereunder", "herein" and "hereby" and each other similar
reference and each reference to "this Agreement" and each other similar
reference contained in the Credit Agreement shall, from and after the date of
effectiveness of this Amendment No. 5, refer to the Credit Agreement as amended
hereby.

         SECTION 2. AMENDMENT TO DEFINITIONS IN CREDIT AGREEMENT. Section 1.01
of the Credit Agreement is hereby amended by amending the following definition
to read in its entirety as follows:

                  "TRANCHE B MATURITY DATE" shall mean the earlier of (a)
         October 31, 2000 and (b) the date on which the sale of the Nitrogen

          SECTION 3. COMMITMENT OF THE DIP LENDERS. Section 2.01(a)(i) of the

<PAGE>
         SECTION 4. WAIVER. (a) Each DIP Lender hereby waives compliance by the

          (b) Other than as specifically provided in paragraph (a) above, this
Amendment and Waiver shall not operate as a waiver of any right, remedy, power
or privilege of the Agent or the DIP Lenders under the Credit Agreement or any
other Loan Document or of any other term or condition thereof.

         SECTION 5. EFFECTIVENESS. This Amendment and Waiver shall become
effective if and only if the Agent shall have received duly executed
counterparts hereof signed by each of the Borrower, the Agent, the Guarantor and
each of the DIP Lenders (or, in the case of any party as to which an executed
counterpart shall not have been received, the Agent shall have received
telegraphic, telex or other written confirmation from such party of execution of
a counterpart hereof by such party).

         SECTION 6. GOVERNING LAW. This Amendment and Waiver shall be governed
by and construed in accordance with the laws of the State of New York.

         SECTION 7. COUNTERPARTS. This Amendment and Waiver may be signed in any
number of counterparts, each of which shall be an original, with the same effect
as if the signatures thereto and hereto were upon the same instrument.

         IN WITNESS WHEREOF, the parties hereto have caused this Amendment and
Waiver to be duly executed by their respective authorized officers as of the day
and year first above written.
