Item 1.01.  Entry into a Material Definitive Agreement.

     On May 25,  2005,  the Board of  Directors  of L. B.  Foster  Company  (the
"Company"),  upon  the  prior  recommendation  of  its  Compensation  Committee,
approved the L.B.  Foster  Company 2005 Three Year  Incentive Plan (the "Plan").
The Plan was  designed to  motivate  senior  officers  to improve the  Company's
performance  over the three year period,  2005 - 2007.  The Company filed a Form
8-K dated May 25, 2005, together with the Plan, with the Securities and Exchange
Commission.

     On October 24, 2006, the Board of Directors,  upon the prior recommendation
of the Compensation Committee, amended the Plan by including LIFO adjustments in
the  calculation of Incentive  Income,  as defined in the Plan. The  anticipated
effect of this amendment  will be to reduce  Incentive  Income.  The amended and
restated  Plan is being filed with the  Securities  and Exchange  Commission  as
Exhibit  10.56 to this Report and is  incorporated  by reference  into this Item
1.01.

Item 8.01.  Other Events.

     On October 24,  2006,  the Board of  Directors  of the  Company  declared a
dividend distribution of one right (a "Right') for each outstanding share of the
Company's  Common  Stock,  par  value  $0.01  per  share  ("Common  Stock'),  to
shareholders  of record at the close of  business on May 15,  2007,  the date on
which the Company's  currently  outstanding,  similar stock purchase rights will
expire.  Except as described below, each Right,  when exercisable,  entitles the
registered  holder to purchase  from the Company one share of Common  Stock at a
purchase price of $30.00 (the  "Purchase  Price"),  subject to  adjustment.  The
description  and terms of the  Rights are set forth in a Rights  Agreement  (the
"Rights  Agreement")  between the Company and  American  Stock  Transfer & Trust
Company,  as Rights Agent.  The following is a general  description  only and is
subject to the detailed terms and conditions of the Rights Agreement.  A copy of
the Rights Agreement,  including the form of Rights  Certificate and the Summary
of Rights to be provided to shareholders of the Company, is being filed with the
Securities and Exchange Commission as Exhibit 4B to this Report.

     Initially,  the Rights will be attached  to all Common  Stock  certificates
representing  shares then outstanding,  and no separate Rights Certificates will
be  distributed.   The  Rights  will  separate  from  the  Common  Stock  and  a
Distribution  Date will occur upon the earlier of (i) 10 days following a public
announcement  that a person or group of affiliated  or associated  persons other
than the Company,  its subsidiaries or any person receiving  newly-issued shares
of Common Stock  directly from the Company or indirectly  via an  underwriter in
connection  with a public  offering by the Company (an  "Acquiring  Person") has
acquired, or obtained the right to acquire,  beneficial ownership of 20% or more
of the outstanding  shares of Common Stock (the "Stock  Acquisition  Date"),  or
(ii) 10 business days following the  commencement  of a tender offer or exchange
offer that would result in a person or group beneficially  owning 20% or more of
such outstanding  shares of Common Stock.  Until the Distribution  Date, (i) the
Rights  will  be  evidenced  by  the  Common  Stock  certificates  and  will  be
transferred with and only with such Common Stock  certificates,  (ii) new Common
Stock   certificates   issued  after  May  15,  2007  will  contain  a  notation
incorporating  the Rights  Agreement by reference  and (iii) the  surrender  for
transfer of any  certificates for Common Stock will also constitute the transfer
of the Rights associated with the Common Stock represented by such certificate.

     The Rights are not exercisable  until the Distribution Date and will expire
at the close of  business  on October  24,  2016,  unless  earlier  redeemed  or
exchanged by the Company as described below.

     As soon as practicable  after the Distribution  Date,  Rights  Certificates
will be mailed to  holders  of  record  of the  Common  Stock as of the close of
business  on  the  Distribution  Date  and,  thereafter,   the  separate  Rights
Certificates alone will represent the Rights.  Except as otherwise determined by
the  Board of  Directors,  only  shares  of  Common  Stock  issued  prior to the
Distribution Date will be issued with Rights.

     If any  person  becomes  an  Acquiring  Person  other  than  pursuant  to a
Qualifying Offer (as defined below), each holder of a Right will thereafter have
the right to receive, upon exercise, Common Stock (or, in certain circumstances,
cash,  property or other  securities of the Company) having a value equal to two
times  the  exercise  price of the  Right.  The  Rights  Agreement  contains  an
exemption for any issuance of Common Stock by the Company directly to any person
(for example,  in a private  placement or an acquisition by the Company in which
Common Stock is used as  consideration)  or  indirectly  via an  underwriter  in
connection  with a public  offering by the  Company,  even if that person  would
become the  beneficial  owner of 20% or more of the  outstanding  Common  Stock,
provided  that such  person does not  acquire  any  additional  shares of Common
Stock.  Notwithstanding  any of the  foregoing,  all Rights  that are, or (under
certain  circumstances  specified in the Rights  Agreement)  were,  beneficially
owned by any  Acquiring  Person will be null and void.  However,  Rights are not
exercisable in any event until such time as the Rights are no longer  redeemable
by the Company as set forth below.

     A  "Qualifying  Offer"  means a tender  offer  or  exchange  offer  for all
outstanding  shares of Common  Stock at a price  and on terms  determined  by at
least a majority of the  Continuing  Directors  (as  defined  below) who are not
officers or  employees  of the Company and who are not related (as  specified in
the Rights  Agreement) to the Person making such offer, to be fair to and in the
best interests of the Company and its shareholders.

     If at any time  following  the Stock  Acquisition  Date (i) the  Company is
acquired  in a merger or other  business  combination  transaction  in which the
Common  Stock is  changed  or  exchanged  or in  which  the  Company  is not the
surviving  corporation  (other than a merger that follows a Qualifying Offer and
satisfies  certain  other  requirements),  or (ii) 50% or more of the  Company"s
assets or earning power is sold or  transferred,  each holder of a Right (except
Rights that have been  previously  voided as set forth above)  shall  thereafter
have the right to receive, upon exercise,  common stock of the acquiring company
having a value equal to two times the  exercise  price of the Right.  The events
set forth in this paragraph and in the second  preceding  paragraph are referred
to as the "Triggering Events."

     The  Purchase  Price  payable,  and the number of shares of Common Stock or
other securities or property  issuable,  upon exercise of the Rights are subject
to adjustment from time to time to prevent  dilution (i) in the event of a stock
dividend on, or a subdivision,  combination or  reclassification  of, the Common
Stock,  (ii) if  holders  of the  Common  Stock are  granted  certain  rights or
warrants to subscribe  for Common Stock or  convertible  securities at less than
the current market price of the Common Stock, or (iii) upon the  distribution to
holders of the Common Stock of evidences of  indebtedness  or assets  (excluding
regular  quarterly cash dividends) or of subscription  rights or warrants (other
than those referred to above).

     With  certain  exceptions,  no  adjustment  in the  Purchase  Price will be
required  until  cumulative  adjustments  amount to at least 1% of the  Purchase
Price. No fractional  shares will be issued and, in lieu thereof,  an adjustment
in cash will be made based on the market  price of the Common  Stock on the last
trading date prior to the date of exercise.

     At any time  until ten days  following  the  Stock  Acquisition  Date,  the
Company may redeem the Rights in whole,  but not in part, at a price of $.05 per
Right (payable in cash, Common Stock or other  consideration  deemed appropriate
by the Board of Directors).  Under certain circumstances set forth in the Rights
Agreement, the decision to redeem shall require the concurrence of a majority of
the Continuing Directors.  Immediately upon the action of the Board of Directors
ordering  redemption  of the Rights or at such other time as may be specified by
the Board when it orders redemption,  with, where required, the concurrence of a
majority of the  Continuing  Directors,  the Rights will  terminate and the only
right of the holders of Rights will be to receive the $.05 redemption price.

     The term "Continuing  Directors" means any member of the Board of Directors
of the  Company  who was a member  of the Board  prior to the Stock  Acquisition
Date, and any person who is subsequently  elected to the Board if such person is
recommended or approved by a majority of the Continuing Directors, but shall not
include an  Acquiring  Person,  or an  affiliate  or  associate  of an Acquiring
Person, or any representative of the foregoing entities.

     Until a Right is  exercised,  the  holder  thereof,  as such,  will have no
rights as a shareholder of the Company, including, without limitation, the right
to vote or to receive  dividends.  While the distribution of the Rights will not
be taxable to shareholders or to the Company,  shareholders may,  depending upon
the circumstances, recognize taxable income if the Rights become exercisable for
Common Stock (or other  consideration) of the Company or for common stock of the
acquiring company as set forth above.

     Other than those provisions relating to the principal economic terms of the
Rights,  any of the  provisions  of the Rights  Agreement  may be amended by the
Board of  Directors of the Company  prior to the  Distribution  Date.  After the
Distribution  Date, the Rights Agreement may be amended by the Board (in certain
circumstances,  with the  concurrence of the  Continuing  Directors) in order to
cure any ambiguity,  to make changes that do not adversely  affect the interests
of holders of Rights  (excluding the interests of any Acquiring  Person),  or to
shorten  or  lengthen  any time  period  under the Rights  Agreement;  provided,
however,  that no amendment to adjust the time period governing redemption shall
be made at a time when the Rights are not redeemable.

     As of October  24,  2006,  there  were  10,520,245  shares of Common  Stock
outstanding  and 727,000  shares of Common Stock  reserved  for  issuance  under
outstanding  options to purchase Common Stock.  Each outstanding share of Common
Stock at the close of  business  on May 15,  2007 will  receive  one  Right.  In
addition,  Rights  shall be issued in respect of all shares of Common Stock that
are issued (whether originally issued or from the Company's treasury) after that
date but prior to the earlier of the  Distribution  Date or the Expiration  Date
and, in certain  circumstances  as provided in the Rights  Agreement,  after the
Distribution Date.
