L.B. Foster Company and Portec Rail Products, Inc. Announce Sale of Certain Assets

Koppers, Inc. to Purchase Portec's Rail Joint Business

PITTSBURGH, December 10, 2010 - L.B. Foster Company ("L.B. Foster", Nasdaq: FSTR) and Portec Rail
Products, Inc. ("Portec", Nasdaq: PRPX) , announce the signing of an Asset
Purchase Agreement ("APA") with Koppers, Inc., a wholly-owned subsidiary of
Koppers Holdings Inc. ("Koppers", NYSE: KOP). Koppers will purchase the
assets of Portec's rail joint business primarily located at Portec's
Huntington, WV Plant. Revenues for this business in 2010 are estimated at
approximately $22 million. This transaction is expected to close by year-end.

Consummation of the divestiture is subject to various conditions
including final approval by the Department of Justice Antitrust Division
("DOJ"), entering into a consent order by Foster and Portec to be filed and
approved by a federal district court judge and Foster's subsidiary notifying
the depositary for its tender offer for Portec's shares that it is accepting
the tendered shares for payment.

Stan L. Hasselbusch, President and CEO of L.B. Foster stated, "We are
very pleased to announce the completion of this critical step in our
acquisition of Portec. We have worked diligently with the DOJ to find an
acceptable solution to their objections to our acquisition. We are also
pleased to be able to sell these assets to Koppers, another Pittsburgh based
supplier to the rail industry."

Mr. Hasselbusch further stated, "We appreciate the tireless efforts of
the DOJ to cooperate with L.B. Foster and Koppers to reach completion of this
APA, and we look forward to their expedited final approval of the divestiture
and their filing of the consent order papers."

Upon judicial approval, the antitrust condition in our tender offer will
be satisfied and L.B. Foster will be able to close the tender offer and
acquire Portec assuming the other conditions of the tender offer are
satisfied.
