B. Foster Company Voluntary Investment Plan We have audited the accompanying statements of net assets available for benefits of the L. B. Foster Company Voluntary Investment Plan as of December 31, 2006 and 2005, and the related statement of changes in net assets available for benefits for the year ended December 31, 2006. 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, 2006 and 2005, and the changes in its net assets available for benefits for the year ended December 31, 2006, 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, 2006 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. /s/ Ernst & Young LLP June 22, 2007 L.

L. B. Foster Company Voluntary Investment Plan Notes to Financial Statements December 31, 2006 and 2005 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 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. Employees may contribute up to 41% of their annual compensation 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. Beginning the first of the month following 12 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 12 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. 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. An additional matching employer contribution of $381,000 was made in 2006. No such contributions were made in 2005. 1. Description of Plan (continued) 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. Discretionary contributions of $626,000 and $494,000 were approved for 2006 and 2005, 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 2006. Forfeitures totaling $300 were utilized to offset contributions in 2005. At December 31, 2006 and 2005, forfeitures approximating $4,800 and $400, 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 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 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 their 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 0.5%. 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 December 2005, the Financial Accounting Standards Board (FASB) issued FASB Staff Position AAG INV-1 and SOP 94-4-1, Reporting of Fully Benefit-Responsive Investment Contracts Held by Certain Investment Companies Subject to the AICPA Investment Company Guide and Defined-Contribution Health and Welfare and Pension Plans (the FSP). The FSP defines the circumstances in which an investment contract is considered fully benefit-responsive and provides certain reporting and disclosure requirements for fully benefit-responsive investment contracts in defined contribution health and welfare and pension plans. The financial statement presentation and disclosure provisions of the FSP are effective for financial statements issued for annual periods ending after December 15, 2006, and are required to be applied retroactively to all prior periods presented for comparative purposes. The Plan has adopted the provisions of the FSP as of December 31, 2006. As required by the FSP, investments in the accompanying Statements of Net Assets Available for Benefits include fully benefit-responsive investment contracts recognized at fair value. AICPA Statement of Position 94-4-1, Reporting of Investment Contracts Held by Health and Welfare Benefit Plans and Defined Contribution Pension Plans, as amended, requires fully benefit-responsive investment contracts to be reported at fair value in the Plan's Statement of Net Assets Available for Benefits with a corresponding adjustment to reflect these investments at contract value. The requirements of the FSP have been applied retroactively to the Statement of Net Assets Available for Benefits as of December 31, 2005, presented for comparative purposes. Adoption of the FSP had no effect on the Statement of Changes in Net Assets Available for Benefits for any period presented. 3. Investments Profit-sharing contributions are directed into the L. B. Foster Company Stock Fund. Participants may subsequently transfer profit-sharing contributions into other plan funds at their discretion. The L. B. Foster Company Stock Fund is a unitized stock fund 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, participant accounts receive units of participation in the fund rather than common shares. 3. Investments (continued) For the year ended December 31, 2006, the Plan's investments (including investments bought, sold, and held during the year) appreciated (depreciated) in value as follows: Net Realized/ Fair Unrealized Market Appreciation Value (Depreciation) --------------------------------- Fidelity investments: Magellan Fund $ 3,934,234 $(665,164) Equity Income Fund 2,658,469 279,362 Growth and Income Fund 3,663,699 (266,054) Government Income Fund 1,201,297 (13,240) Blue Chip Fund 365,075 10,038 Asset Manager Fund 1,040,373 2,250 Low Price Stock Fund 2,192,096 139,065 Small Cap Stock Fund 1,049,586 24,809 Freedom Income Fund 110,217 1,212 Freedom 2000 27,839 1,818 Freedom 2010 934,726 33,305 Freedom 2020 1,518,605 72,226 Freedom 2030 540,554 29,217 Freedom 2040 324,377 17,226 Managed Income Portfolio 1,429,775 - Retirement Government Money Market Fund 2,393,482 - Spartan U.S. Equity Index Fund 3,311,564 389,718 Credit Suisse Emerging Growth Fund 534,849 4,803 PIMCO Total Return Fund 1,448,064 (18,961) Allianz NFJ Small Cap Value Fund 1,012,470 33,548 MSI International Equity Fund 3,336,370 22,089 L.

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 sponsor has indicated that it will take the necessary steps, if any, to bring the Plan's operations into compliance with the Code. 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. 6.

Foster Company Retirement Savings Plan has been terminated. The consolidated plan is the L. B. Foster Company 401(k) and Profit Sharing Plan.
