Forward-Looking Statements

This press release contains “forward-looking statements”. Such statements include, but are not limited to, statements about the anticipated timing of the closing of the transaction involving L.B. Foster and Portec and the expected benefits of the transaction, including potential synergies and cost savings, future financial and operating results, and the combined company’s plans and objectives. In addition, statements made in this communication about anticipated financial results, future operational improvements and results or regulatory approvals are also forward-looking statements. These statements are based on current expectations of future events. If underlying assumptions prove inaccurate or unknown risks or uncertainties materialize, actual results could vary materially from L.B. Foster’s and Portec’s expectations.

Risks and uncertainties include the satisfaction of closing conditions for the acquisition, including clearance under the Hart-Scott-Rodino Antitrust Improvements Act; the tender of sixty-five percent of the outstanding shares of common stock of Portec Rail Products, Inc., calculated on a fully diluted basis; the possibility that the transaction will not be completed, or if completed, not completed on a timely basis; the potential that market segment growth will not

follow historical patterns; general industry conditions and competition; business and economic conditions, such as interest rate and currency exchange rate fluctuations; technological advances and patents attained by competitors; and domestic and foreign governmental laws and regulations. L.B. Foster can give no assurance that any of the transactions related to the tender offer will be completed or that the conditions to the tender offer and the merger will be satisfied. A further list and description of additional business risks, uncertainties and other factors can be found in Portec’s Annual Report on Form 10-K for the fiscal year ended December 31, 2009, as well as other Portec SEC filings and in L.B. Foster’s Annual Report on Form 10-K for the fiscal year ended December 31, 2009 as well as other L.B. Foster SEC filings. Copies of these filings, as well as subsequent filings, are available online at www.sec.gov, www.portecrail.com and www.lbfoster.com. Many of the factors that will determine the outcome of the subject matter of this communication are beyond L.B. Foster’s or Portec’s ability to control or predict. Neither L.B. Foster nor Portec undertakes to update any forward-looking statements as a result of new information or future events or developments.
