                         Report of Independent Auditors


Plan Administrator
L. B. Foster Company
Voluntary Investment Plan

We have audited the accompanying statements of net assets available for benefits
of L. B. Foster Company  Voluntary  Investment  Plan as of December 31, 2002 and
2001, and the related  statement of changes in net assets available for benefits
for the year  ended  December  31,  2002.  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 in accordance with auditing standards generally accepted
in the United States. 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 financial  statements  referred to above present fairly, in
all  material  respects,  the net assets  available  for benefits of the Plan at
December  31,  2002 and 2001,  and the changes in its net assets  available  for
benefits for the year ended  December 31, 2002,  in conformity  with  accounting
principles generally accepted in the United States.

Our audits were performed for the purpose of forming an opinion on the financial
statements taken as a whole. The  accompanying  supplemental  schedule of assets
held  at end of  year as of  December  31,  2002 is  presented  for  purpose  of
additional  analysis and is not a required part of the 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 our  audits  of the  financial  statements  and,  in our
opinion,  is fairly stated in all material respects in relation to the financial
statements taken as a whole.

                          Notes to Financial Statements

                     Years ended December 31, 2002 and 2001


1. DESCRIPTION OF PLAN

The following brief description of the L. B. Foster Company Voluntary Investment
Plan (the Plan) as amended  effective  January 1, 1999 is  provided  for general
information  purposes  only.  Participants  should  refer  to the  summary  plan
description for more complete information.

GENERAL

The Plan is a  defined  contribution  plan  extended  to all  eligible  salaried
employees of L. B. Foster Company (the Company) who have attained age 18. The L.
B. Foster Company Employee  Benefits Policy and Review  Committee,  appointed by
the  Board  of  Directors  of the  Company,  collectively  serves  as  the  plan
administrator.  The Plan is subject to the provisions of the Employee Retirement
Income Security Act of 1974 (ERISA) as amended.

CONTRIBUTIONS

Contributions  under the Plan are made by both the participants and the Company.
A participant may elect to make pretax  contributions  ranging from 2% to 10% of
annual compensation subject to Internal Revenue Code limitations.  A participant
who elects to make pretax  contributions  of at least the maximum amount subject
to company matching can also elect to make additional voluntary contributions on
an after-tax basis provided,  however,  that the sum of the pretax and voluntary
employee   contributions  does  not  exceed  15%  of  the  participant's  annual
compensation.  Participant contributions and employer matching contributions are
invested  in  accordance  with  participant  elections.  In  the  event  that  a
participant does not make an investment election,  contributions are invested in
the  Fidelity  Freedom  funds  until  such  time as an  election  is made by the
participant. The participant may transfer contributions defaulted to these funds
into other investment options at the participant's discretion.

Beginning  the first of the month  following  twelve months of  employment,  the
Company provides a 50% match of the  participant's  primary  contribution on the
first 4% to 6% of annual compensation,  based on years of service, as defined by
the  Plan.  Beginning  the  first  of  the  month  following  twelve  months  of
employment,  the  Company  contributes  a fixed  amount  equal to 1% of eligible
employees'  annual  compensation  regardless  of whether the employee  elects to
contribute to the Plan. Company contributions may be reduced by forfeitures that
accumulate.

                            Voluntary Investment Plan

                    Notes to Financial Statements (continued)


1. DESCRIPTION OF PLAN (CONTINUED)

The Plan also requires an additional  matching  employer  contribution  of up to
$.50 for each $1.00 of eligible pretax  contributions based on a target ratio of
the Company's annual pretax income to equity as defined in the Plan.  Additional
matching employer contributions were not required in 2002.

The Company, upon resolution of the Board of Directors, may make a discretionary
additional contribution of an amount out of, but not in excess of, the Company's
current or accumulated  profits. No discretionary  contribution was approved for
2002.  The  Company's  contributions  may be  reduced by any  forfeitures  which
accumulate   from   terminations  of   participants   with  nonvested   employer
contributions.   Forfeitures   totaling   $79,100   were   utilized   to  offset
contributions in 2002. At December 31, 2002 and 2001, forfeitures of $25,600 and
$109,800, respectively, were available to reduce future company contributions.

VESTING

A  participant's  vested interest in the Plan on any date is equal to the sum of
the values of (a) that portion of the participant's  account attributable to the
participant's  contributions and (b) that portion of the  participant's  account
attributable to the Company's contributions multiplied by the applicable vesting
percentage plus or minus related earnings (losses). Participants that are active
as of January 1, 2002 or later are 100%  vested in the  Company's  contributions
after three years of eligible  service or after  attaining age 65.  Participants
that are inactive as of or  terminated  prior to January 1, 2002 are 100% vested
in the  Company's  contributions  after five years of eligible  service or after
attaining age 65.

Notwithstanding  the above, a participant who terminates from the Plan by reason
of retirement, disability, or death is fully vested in his participant account.

DISTRIBUTIONS

Normal  retirement  age is 65. Early  retirement  age is 55,  provided  that the
participant has at least five years of service.  In addition,  a participant may
obtain an early retirement  distribution prior to reaching age 55, provided that
the participant  will turn 55 in the year the  distribution  occurs and that the
participant has at least five years of service.

As provided by the Plan, the  distribution to which a participant is entitled by
reason of normal, early, late, or disability  retirement,  death, or termination
of  employment  may be made in the form of direct  rollover,  annuity,  cash, or
partly in cash and  partly as an  annuity.  The amount of such  distribution  is
equal to the participant's vested account balance on the valuation date.

1. DESCRIPTION OF PLAN (CONTINUED)

WITHDRAWALS

Under  the  Plan,  a  participant  may elect to  withdraw  voluntary,  after-tax
contributions  made to the Plan prior to January 1, 1987.  Such  withdrawals are
subject to a $1,000  minimum.  In the event of extreme  hardship  and subject to
certain  restrictions  and  limitations,  a participant  may withdraw his vested
interest in the  portion of his  account  attributable  to  matching,  fixed and
discretionary contributions, and related earnings.

PARTICIPANTS' ACCOUNTS

Each  participant's  account  is  credited  with the  participant's  pretax  and
voluntary   contributions,   the   participant's   allocable  share  of  company
contributions,  and related earnings of the funds. Participants' accounts may be
invested in 10% increments into any of the mutual funds available under the Plan
at the direction of the participant.

LOANS

A participant may obtain a loan from the vested portion of his account,  subject
to spousal consent,  if applicable.  The loan proceeds  (subject to a minimum of
$1,000 and a maximum of $50,000) are deducted from the participant's account and
are  repaid by means of  payroll  deductions.  Loans are  required  to be repaid
within 60 months from the date on which the loan is  originally  granted and may
be  prepaid  early  without  penalty.  The  repayment  period for a loan that is
obtained for  purchasing a primary  residence may be as long as 360 months.  The
loan carries an interest rate computed at the prime rate plus one-half  percent.
The  interest  rate is  computed on the date the loan is  requested  and remains
fixed for the full term of the loan.

PLAN TERMINATION

Although it has not  expressed any intention to do so, the Company has the right
under the Plan to discontinue its contributions at any time and to terminate the
Plan  subject  to the  provisions  of  ERISA.  Should  the  Plan be  terminated,
participants  will become fully vested in their accounts,  and the assets of the
Plan would be distributed to the participants  based on their individual account
balances as determined under the plan provisions.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

VALUATION OF INVESTMENTS

Mutual fund values are based on the underlying investments in securities. Mutual
fund  securities  traded on security  exchanges  are valued at the latest quoted
sales price.  Securities traded on a national  securities exchange are valued at
the  last  reported  sales  price  on the last  business  day of the plan  year.
Securities traded in the over-the-counter market and listed securities for which
no sale was  reported  on that fixed rate date are valued at the  average of the
last reported bid and ask quotations.  Loans  receivable from  participants  are
valued at cost which approximates fair value.

Realized  gain or loss  includes  recognized  gains  and  losses  on the sale of
investments. Unrealized appreciation or depreciation represents changes in value
from original  cost.  Dividend  income is recorded on the  ex-dividend  date and
interest income is accrued as earned.

As  described  above,  the assets of the Plan are  concentrated  in mutual funds
consisting  primarily of stocks and bonds.  Realization of amounts  disclosed as
net assets available for benefits is dependent on the results of these markets.

BASIS OF ACCOUNTING

The  financial  statements  of the Plan are  maintained  on the  accrual  basis.
Contributions  receivable  are recorded among the available  investment  options
based upon the participants'  aggregate investment  allocations in effect at the
end of the plan year.

USE OF ESTIMATES

The preparation of financial statements in accordance with accounting principles
generally  accepted in the United States  requires  management to make estimates
that affect the amounts  reported in the financial  statements and  accompanying
notes. Actual results could differ from those estimates.

EXPENSES

The  Company,  as provided  by the Plan,  pays  expenses  of the Plan.  Expenses
incurred  to  establish  and  maintain  a loan  are  charged  to the  applicable
participant.

                    Notes to Financial Statements (continued)

3. INVESTMENTS

Effective January 1, 1999, the Plan was amended to establish an investment
option in which  employees  may invest  contributions  in L. B.  Foster  Company
common stock.  All profit sharing  contributions  occurring  after the effective
date will be directed into the L. B. Foster Company Stock Fund. Participants may
subsequently  transfer  profit  sharing  contributions  into other plan funds at
their  discretion.  During 2001, the Company  converted the L. B. Foster Company
Stock Fund into a unitized  stock fund. The unitized fund will be comprised of a
95% to 99% investment in L. B. Foster Company common stock with the remaining 1%
to 5% invested in a short-term  investment  fund. As a result of the conversion,
participant  accounts  receive  units of  participation  in the fund rather than
common  shares.  The conversion  grants  participants  the added  flexibility of
executing daily  transactions to increase or decrease  participation in the fund
that was not present under the prior fund structure.

For the  year  ended  December  31,  2002,  the  Plan's  investments  (including
investments bought, sold, and held during the year) appreciated (depreciated) in
value as follows:

                                                              Net Realized/

4. INCOME TAX STATUS

The Plan has received a determination  letter from the Internal  Revenue Service
(IRS) dated July 30,  2002,  stating that the Plan is  qualified  under  Section
401(a) of the Internal Revenue Code (the Code) and, therefore, the related trust
is exempt  from  taxation.  Once  qualified,  the Plan is required to operate in
conformity  with the Code to maintain  its  qualification.  The Plan was amended
subsequent to the IRS determination letter. The plan administrator  believes the
Plan is being  operated in compliance  with the applicable  requirements  of the
Code and,  therefore,  believes that the Plan is qualified and the related trust
is tax-exempt.

5. TRANSACTIONS WITH PARTIES-IN-INTEREST

Certain  trustee,  accounting,  and  administrative  expenses  relating  to  the
maintenance of participant records and the Plan's administration are absorbed by
the Company.
