                          INDEPENDENT AUDITORS' REPORT



Stockholders and Board of Directors
Rentech, Inc.
Denver, Colorado


We have audited the accompanying  consolidated  balance sheets of Rentech,  Inc.
and  Subsidiaries  (the  "Company") as of September  30, 2002 and 2001,  and the
related  consolidated  statements of operations,  stockholders'  equity and cash
flows for each of the three years in the period ended September 30, 2002.  These
financial  statements are the  responsibility of the Company's  management.  Our
responsibility  is to express an opinion on these financial  statements based on
our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the  United  States of  America.  Those  standards  require  that we plan and
perform the audit to obtain  reasonable  assurance  about  whether the financial
statements are free of material misstatement.  An audit includes examining, on a
test basis,  evidence  supporting  the amounts and  disclosures in the financial
statements.  An audit also includes assessing the accounting principles used and
significant  estimates  made by  management,  as well as evaluating  the overall
financial  statement  presentation.   We  believe  that  our  audits  provide  a
reasonable basis for our opinion.

In our opinion, the consolidated  financial statements referred to above present
fairly, in all material  respects,  the financial  position of the Company as of
September 30, 2002 and 2001 and the results of their  operations  and their cash
flows for each of the three  years in the period  ended  September  30,  2002 in
conformity with accounting principles generally accepted in the United States of
America.

The accompanying  financial  statements have been prepared  assuming the Company
will  continue  as a going  concern.  As  discussed  in Note 1 to the  financial
statements, the Company has experienced  circumstances,  which raise substantial
doubt  about its  ability to continue  as a going  concern.  Management's  plans
regarding  those matters also are described in Note 1. The financial  statements
do not  include  any  adjustments  that might  result  from the  outcome of this
uncertainty.
