             REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


The Plan Administrator
L. B. Foster Company
401(k) and Profit Sharing Plan

We have audited the accompanying statements of net assets available for benefits
of the L. B. Foster Company 401(k) and Profit Sharing Plan  (formerly,  the L.B.
Foster Company Voluntary  Investment Plan) as of December 31, 2007 and 2006, and
the related  statement of changes in net assets  available  for benefits for the
year ended December 31, 2007. 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 the standards of the Public  Company
Accounting Oversight Board (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.  We were not engaged to perform an
audit of the  Plan's  internal  control  over  financial  reporting.  Our audits
included  consideration of internal control over financial  reporting as a basis
for designing audit  procedures that are appropriate in the  circumstances,  but
not for the purpose of expressing an opinion on the  effectiveness of the Plan's
internal  control  over  financial  reporting.  Accordingly,  we express no such
opinion. An audit also 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 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,  2007 and 2006,  and the changes in its net assets  available  for
benefits for the year ended December 31, 2007, in conformity with U.S. generally
accepted accounting principles.

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,  2007 is  presented  for  purposes 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

                           December 31, 2007 and 2006


1. Description of Plan

Effective March 1, 2007, the Company merged the L. B. Foster Company  Retirement
Savings  Plan into the L. B.  Foster  Company  Voluntary  Investment  Plan.  The
consolidated  plan became the L. B.  Foster  Company  401(k) and Profit  Sharing
Plan.  The following  brief  description  of the L. B. Foster Company 401(k) and
Profit  Sharing  Plan (the Plan) is provided for general  information  purposes.
Participants  should refer to the summary  plan  description  for more  complete
information.

General

The Plan is a defined contribution plan extended to all eligible 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  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.  Participants may contribute up to 75% of
their annual pre-tax  compensation  and up to 100% of their  compensation  on an
after-tax basis, subject to Internal Revenue Code limitations. There is no limit
on aggregate pretax and after-tax contributions.  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.

The Plan includes a provision for immediate Company match.  Participants receive
a Company match of 100% on the first 1% of their eligible  compensation  and 50%
of the next 6% of their eligible compensation for a maximum Company match of 4%.
To be eligible for the Company matching  contributions,  participants  must make
employee  pretax  deferral  contributions  or Roth  401(k)  after  tax  deferral
contributions.  The plan will match on the combined total of these contributions
up to the matching limit.

                          Notes to Financial Statements


1. Description of Plan (continued)

The Company, upon resolution of the Board of Directors, may make a discretionary
profit  sharing  contribution  of an amount  out of,  but not in excess  of, the
Company's  current  or  accumulated  profits.   Discretionary  contributions  of
$1,000,000  and  $626,000  were  approved  for  2007  and  2006,   respectively.
Forfeitures  of  discretionary  contributions  are  reallocated  to  the  Plan's
remaining,  eligible  participants.  The Company's matching contributions may be
reduced by any forfeitures  that  accumulate  from  terminations of participants
with nonvested  employer  matching  contributions.  No forfeitures were utilized
during 2007 or 2006.  At December 31, 2007 and 2006,  forfeitures  approximating
$31,400  and $4,800,  respectively,  were  available  to reduce  future  company
contributions.  Participants  must have  attained  one year of service as of the
last day of the Plan Year in order to be eligible for the  discretionary  profit
sharing contribution, if any, for that year.

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 are 100% vested
in  the   Company's   contributions   after  two  years  of  eligible   service.

Notwithstanding  the above, a participant who terminates from the Plan by reason
of  retirement,  disability,  or  death  is fully  vested  in their  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 their vested
interest  in  the  portion  of  their  account,   subject  to  a  $500  minimum,
attributable to matching,  fixed, and discretionary  contributions,  and related
earnings.  The Plan also allows for age 59 1/2 in-service  withdrawals of all or
any portion of the participant's vested account balance.

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  equal to the  lesser of 50% of their  vested
account   balance  or  $50,000.   The  loan   proceeds  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 a reasonable interest rate as determined by
the  Plan  Sponsor.  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.  The
contract  value of  participation  units owned in the  collective  trust fund is
based on quoted  redemption  values,  as determined by the Trustee,  on the last
business day of the plan year.  The fair value of  participation  units owned by
the  collective  trust  fund is  determined  based on the  present  value of the
underlying  contracts'  cash  flows,  discounted  at  current  market  rates for
investments of similar quality and duration.  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 U.S.  generally
accepted accounting principles 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.

2. Summary of Significant Accounting Policies (continued)

New Accounting Pronouncement

In September 2006, the Financial  Accounting Standards Board issued Statement of
Financial  Accounting  Standards  No. 157, Fair Value  Measurements  (SFAS 157),
which  establishes  a framework  for  measuring  fair value in  accordance  with
generally  accepted  accounting  principles and expands  disclosures  about fair
value  measurements.  SFAS 157 is  effective  for fiscal years  beginning  after
November 15, 2007.  The Plan is  currently  evaluating  the impact that SFAS 157
will have on its financial statements.

3. Investments

Discretionary   profit-sharing   contributions   are  directed   into   eligible
