Report of Independent Accountants

To the Participants and Administrator of
Keystone Consolidated Industries, Inc. Deferred Incentive Plan


In our opinion, the accompanying statements of net assets available for benefits
and the  related  statement  of  changes in net assets  available  for  benefits
present fairly, in all material respects,  the net assets available for benefits
of Keystone Consolidated  Industries,  Inc. Deferred Incentive Plan (the "Plan")
at December  31,  1999 and 2000,  and the  changes in net assets  available  for
benefits for the year ended  December  31, 2000 in  conformity  with  accounting
principles  generally accepted in the United States of America.  These financial
statements are the responsibility of the Plan's  management;  our responsibility
is to express an opinion on these financial  statements based on our audits.  We
conducted our audits of these  statements in accordance with auditing  standards
generally  accepted in the United States of America,  which 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,  assessing the accounting  principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for the opinion  expressed
above.

Our audits  were  conducted  for the  purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental  schedule of Schedule of
Assets Held For  Investment  Purposes is presented for the purpose of additional
analysis and is not a required  part of the basic  financial  statements  but is
supplementary  information  required  by the  Department  of  Labor's  Rules and
Regulations for Reporting and Disclosure  under the Employee  Retirement  Income
Security Act of 1974. This  supplemental  schedule is the  responsibility of the
Plan's management.  The supplemental schedule has been subjected to the auditing
procedures  applied in the audit of the basic  financial  statements and, in our
opinion,  is fairly  stated in all  material  respects  in relation to the basic
financial statements taken as a whole.

         KEYSTONE CONSOLIDATED INDUSTRIES, INC. DEFERRED INCENTIVE PLAN

                          NOTES TO FINANCIAL STATEMENTS



Note 1 - Description of Plan and significant accounting policies

     General. The following description of the Keystone Consolidated Industries,
Inc.  Deferred  Incentive Plan (the "Plan")  provides only general  information.
Participants should refer to the Plan agreement for a more complete  description
of the Plan's provisions.

     The Plan is a defined  contribution  plan in which eligible  non-bargaining
employees  of  Keystone  Consolidated   Industries,   Inc.  ("Keystone"  or  the
"Employer")  who have at least one year of eligible  service and are at least 21
years old may elect to  participate.  The Plan is a  qualified  cash or deferred
profit-sharing  plan under  Sections  401(a) and 401(k) of the Internal  Revenue
Code of 1986, as amended (the "Code"),  and is subject to the  provisions of the
Employee Retirement Income Security Act of 1974, as amended ("ERISA").

     Contran Corporation ("Contran") and other entities related to Mr. Harold C.
Simmons own 50% of Keystone.  Substantially all of Contran's  outstanding voting
stock is held by trusts  established  for the  benefit of certain  children  and
grandchildren of Mr. Simmons, of which Mr. Simmons is sole trustee. Keystone may
be deemed to be controlled by Contran and Mr. Simmons.

     Contributions.  The Plan permits  participants  to defer 3% to 15% of their
pre-tax  annual  compensation  as  contributions,  not to exceed a  deferral  of
$10,500, (subject to adjustment in future years), through payroll deductions. At
its  discretion,  the Employer may contribute  cash or shares of Keystone common
stock to the Plan based on a matching  or other  formula.  The  Employer's  cash
contributions  are  allocated  to  participants'  accounts  on a  percentage  or
matching basis  relative to the  participants'  contributions  for the year. The
Employer's   contributions  of  Keystone  common  stock  are  allocated  to  the
respective  participants'  accounts in the Keystone  Restricted  Stock Fund. The
Employer's  contribution  is  reduced,  as provided  by the Plan,  by  nonvested
amounts  forfeited by  participants  who withdraw from the Plan. At December 31,
1999 and 2000, unallocated forfeited nonvested accounts were $15,137 and $20,990
respectively.  The  Employer  may use  forfeited  nonvested  accounts  to reduce
Employer  contributions in the fifth year following the plan year of forfeiture.
There  were  $6,228  allocated  to  participant  accounts  during the year ended
December 31, 2000.

     Vesting and benefits.  Salary deferrals  (including  earnings  thereon) are
immediately  vested while Employer  contributions  (including  earnings thereon)
vest at the rate of 20% per year of service, as defined.

     Upon  termination  of  employment,   retirement,  death  or  disability,  a
participant  (or  beneficiary,  if applicable) may elect to receive either (i) a
lump sum amount equal to the vested value of the participants'  accounts or (ii)
installments  over a period of not more than 30 years.  With the  consent of the
Plan  administrators,  participants can borrow amounts from their vested account
balances, subject to certain limitations under the Plan.

     Participants'  accounts.  The Plan  provides  participants  with options to
generally  invest account balances in certain  publicly-traded  mutual or pooled
funds  administered  by Putnam  Investments.  Participants  can  direct the Plan
administrator to invest, in 10% increments,  such account balances in any of the
Plan's  investment fund options.  Employer  contributions  of shares of Keystone
common  stock are  allocated  to  participant  accounts  through  the  "Keystone
Restricted  Stock Fund."  Participants  are not  permitted to redirect  Keystone
Restricted Stock to other investment options.

     In addition to the Putnam Funds, a "Loan Fund" is maintained to account for
loans to  participants,  as permitted by the Plan.  These loans,  with  interest
rates ranging from 7.5% to 10.50%, mature through 2021.

     During 1988, in connection  with  Keystone's  rights offering of its common
stock,  certain  participants  were  permitted  to direct part of their  account
balance  into  an  investment  in   Keystone's   common  stock  (the   "Keystone
Unrestricted Stock Fund").

     Plan termination.  The Employer has the right under the Plan to discontinue
its  contributions at any time and to terminate the Plan, in compliance with the
provisions of ERISA.  In the event the Plan is  terminated,  the accounts of all
participants would become fully vested.

     Basis of accounting.  The financial  statements of the Plan are prepared in
accordance with accounting principles generally accepted in the United States of
America. Valuation of investments is more fully described in Note 2.

     Expenses of administering the Plan. To the extent not paid by the Employer,
administrative  expenses are paid by the Plan.  The Employer  paid a significant
portion of 2000 administrative expenses.

     Management estimates. The preparation of the Plan's financial statements in
conformity with accounting principles generally accepted in the United States of
America  requires  the plan  administrator  to make  significant  estimates  and
assumptions  that  affect  the  reported  amounts of net  assets  available  for
benefits at the date of the financial  statements  and the changes in net assets
available for benefits during the reporting period and disclosures of contingent
assets and liabilities at the date of the financial  statements.  Actual results
could differ from those estimates.

     Risks and  uncertainties.  The Plan provides for various investment options
in a variety of stocks, bonds, fixed income securities,  mutual funds, and other
investment securities.  Investment securities are exposed to various risks, such
as interest rate,  market, and credit risks. Due to the level of risk associated
with certain  investment  securities,  it is at least  reasonably  possible that
changes in the values of investment  securities  will occur in the near term and
that such changes could materially affect participants' account balances and the
amounts reported in the Plan's statement of net assets available for benefits.

     Tax status. The Plan has been notified by the Internal Revenue Service that
it is a qualified  plan under Section 401(a) and Section 401(k) of the Code, and
is therefore exempt from federal income taxes under provisions of Section 501(a)
of the Code.

Note 2 -  Investments

     General.  The  assets  of the  Plan are  held  and the  related  investment
transactions  are  executed by Putnam  Fiduciary  Trust  Company as trustee (the
"Trustee")  of the  Keystone  Master  Deferred  Incentive  Trust (the  "Keystone
Trust"). The Keystone Trust invests in certain  publicly-traded mutual or pooled
funds  administered by Putnam  Investments (see Note 1). The Plan's  investments
are stated at fair value based on quoted market prices and net  appreciation for
the year is reflected in the Plan's statement of changes in net assets available
for plan benefits.

     Investments that individually represent 5% or more of the Plan's net assets
at year end are as follows:
