CLIMACHEM, INC.

UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL INFORMATION

The Unaudited Pro Forma Consolidated Statement of Operations for the nine months ended September 30, 2000 and the year ended December 31, 1999 (the "Pro Forma Statements of Operations"), and the Unaudited Pro Forma Consolidated Balance Sheet as of September 30, 2000 (the "Pro Forma Balance Sheet" and, together with the Pro Forma Statements of Operations, the "Pro Forma Financial Statements"), have been prepared to reflect the lease of the Cherokee Plant by the Company from the Company's parent, LSB Industries, Inc. ("LSB"), as of January 1, 1999 in the Pro Forma Statement of Operations and the purchase of the inventory from LSB as of September 30, 2000 in the Pro Forma Balance Sheet. The Pro Forma Balance Sheet as of September 30, 2000 reflects the historical accounts of ClimaChem, Inc. (the "Company" or "CCI") as of September 30, 2000 combined with the fair value of the Cherokee Plant's inventory acquired as of October 31, 2000. The Pro Forma Statement of Operations for the year ended December 31, 1999 reflects the Company's historical Statement of Operations for the twelve months ended December 31, 1999 and the Cherokee Plant's historical Statement of Revenues and Direct Expenses for the twelve months ended February 29, 2000. For purposes of the Pro Forma Statement of Operations for the nine-month period ended September 30, 2000, the Cherokee Plant's historical Statement of Revenues and Direct Expenses for the seven months ended September 30, 2000 was combined with the Cherokee Plant's historical revenues and direct expenses for January and February 2000 and then was combined with the Company's historical Statement of Operations for the nine-month period ended September 30, 2000. The Pro Forma Financial Statements do not reflect any anticipated cost savings, synergies or additional sales, distribution and marketing costs that may result from the acquisition of the Cherokee Plant by LSB or the related lease of the Cherokee Plant to the Company. The Pro Forma Financial Statements do not purport to be indicative of the results of operations or financial position of the Company that would have actually been obtained had such transactions been completed as of the assumed dates and for the periods presented, or which may be obtained in the future. The pro forma adjustments are described in the accompanying notes and are based upon available information and certain assumptions that the Company believes are reasonable. The Pro Forma Financial Statements should be read in conjunction with the separate historical consolidated financial statements of the Company and the notes thereto and "Management's Discussion and Analysis of Financial Condition and Results of Operations" included in the Company's Form 10-K for the year ended December 31, 1999 and Form 10-Q for the nine months ended September 30, 2000 previously filed with the Securities and Exchange Commission and the historical Statements of Assets Acquired and Liabilities Assumed and Revenues and Direct Expenses of the Cherokee Plant the notes thereto included elsewhere herein.

These pro forma adjustments are based upon available information and certain assumptions that the Company believes to be reasonable. Consequently, the amounts reflected in the Pro Forma Financial Statements are subject to change, and the final amounts may differ substantially.

SUPPLEMENTAL INFORMATION

The accompanying unaudited pro forma consolidated statements of operations for the nine months ended September 30, 2000, and the year ended December 31, 1999, are not reflective of the incremental selling, general and administrative expense which the Company expects to incur associated with the Cherokee Plant. The Company will utilize its existing infrastructure of selling, general and administrative personnel to manage and oversee the operations of the Cherokee Plant; however, the Company estimates that the going-forward incremental cost for the twelve-month period following the date of lease from LSB related to the Cherokee Plant will approximate $1.2 million. This estimate is subject to change based on the facts and circumstances surrounding the operation of the Cherokee Plant.
