1.1 Purpose.  The purpose of this Plan is to provide  financial  incentives  for
officers  and  directors  of  L.B.   Foster  Company  (the  "Company")  and  its
subsidiaries,  thereby  promoting the long-term growth and financial  success of
the  Company  by  (i)  attracting  and  retaining   officers  and  directors  of
outstanding  ability,  (ii)  strengthening the Company's  capability to develop,
maintain and direct a competent  management team,  (iii) motivating  officers to
achieve  long-range  performance  goals  and  objectives,   and  (iv)  providing
incentive   compensation   opportunities   competitive   with   those  of  other
corporations.

1.2 Effective  Date and Expiration of Plan. The Plan was adopted by the Board of
Directors  of the Company on October 23, 1998 and was made  effective as of that
date.  Unless earlier  terminated by the Board pursuant to Section 5.3, the Plan
shall  terminate on the fifth  anniversary of its Effective Date. No Award shall
be made pursuant to the Plan after its  termination  date, but Awards made prior
to the termination date may extend beyond that date.

1.3 Shares  Available  Under the Plan.  L.B.  Foster Company stock to be offered
under the Plan  pursuant  to Options  and SARs may be  authorized  but  unissued
common  stock or  previously  issued  shares of  common  stock  which  have been
reacquired  by the Company and are held in its  treasury.  Subject to adjustment
under  Section 5.6, no more than 25,000 shares of common stock shall be issuable
upon the exercise of Options or SARs.  Any shares of stock  subject to an Option
which  for any  reason  is  cancelled  (excluding  shares  subject  to an Option
cancelled upon the exercise of a related SAR) or terminated  without having been
exercised shall again be available for Awards under the Plan.  Shares subject to
an Option cancelled upon the exercise of an SAR shall not again be available for
Awards under the Plan.

                                   ARTICLE IV

                                     AWARDS


4.1 Awards.  Awards  under the Plan shall  consist of Incentive  Stock  Options,
Nonqualified Stock Options and/or SARs. All Awards shall be subject to the terms
and  conditions  of the Plan and to such other terms and  conditions  consistent
with the Plan as the Committee deems appropriate. Awards need not be uniform.

4.2  Eligibility  for Awards.  Awards may be made to Officers and Directors.  In
selecting  Participants and in determining the form and amount of the Award, the
Committee may give  consideration to his or her functions and  responsibilities,

relevant by the Committee.

4.3 Award of Stock  Options.  The Committee  may, from time to time,  subject to
Section 3.2(b) and other provisions of the Plan and such terms and conditions as
the Committee may  prescribe,  grant  Incentive  Stock Options and  Nonqualified

and Nonqualified Stock Options shall be separate and not in tandem.

4.4 Period of Option.  (a) Unless otherwise provided in the related Stock Option
Agreement,  an Option  granted  under the Plan shall be  exercisable  only after
twelve (12) months have elapsed







from the date of grant and, after such twelve-month  waiting period,  the Option
may be exercised in cumulative installments in the following manner:

                           (i) The  Participant  may  purchase up to  one-fourth
         (1/4) of the total optioned  shares at any time after one year from the
         date of grant and prior to the termination of the Option.

                           (ii) The  Participant may purchase an additional one-
         fourth (1/4) of the total  optioned  shares at any time after two years
         from the date of grant and prior to the termination of the Option.

                           (iii) The Participant may purchase an additional one-
         fourth (1/4) of the total optioned shares at any time after three years
         from the date of grant and prior to the termination of the Option.

                           (iv) The  Participant may purchase an additional one-
         fourth (1/4) of the total optioned  shares at any time after four years
         from the date of grant and prior to the termination of the Option.

                           The  duration  of each  Option  shall not be more 
than ten (10)  years  from the date of grant.

(b) Except as otherwise  provided in the Stock Option  Agreement,  an Option may
not  be  exercised  by a  Participant  unless  such  Participant  is  then,  and
continually (except for sick leave,  military service or other approved leave of
absence) after the grant of an Option has been, an officer, director or employee
of the Company or a Subsidiary.

4.5 Stock  Option  Agreement.  Each Option  shall be evidenced by a Stock Option
Agreement, in such form and containing such provisions not inconsistent with the
provisions of the Plan as the Committee from time to time shall approve.

4.6 Option Price and  Exercise.  (a) The Option Price of Stock under each Option
shall be  determined by the Committee but shall be not less than the Fair Market
Value of the Stock on the trading day  immediately  preceding  the date on which
the Option is granted, as determined by the Committee.

(b)  Options  may be  exercised  from time to time by giving  written  notice of
exercise to the Company  specifying  the number of shares to be  purchased.  The
notice of  exercise  shall be  accompanied  by (i) payment in full of the Option
Price in cash,  certified check or cashier's check or (ii) a copy of irrevocable
instructions  to a broker to promptly  deliver to the Company the amount of sale
or loan proceeds sufficient to cover the Option Price.



Delivery  of Option  Shares.  The  Company  shall not be
obligated to deliver any shares upon the exercise of an Option unless and until,
in the opinion of the Company's counsel, all applicable federal, state and other
laws and regulations have been complied with. In the event the outstanding Stock
is at the time listed on any stock  exchange,  no delivery  shall be made unless
and until the shares to be delivered  have been listed or authorized to be added
to the list upon official notice of issuance on such exchange. No delivery shall
be made  until all other  legal  matters in  connection  with the  issuance  and
delivery of shares have been approved by the Company's counsel.

Without  limiting the generality of the foregoing,  the Company may require from
the Participant or other person  purchasing  shares of Stock under the Plan such
investment  representation or such agreement, if any, as counsel for the Company
may consider  necessary in order to comply with the  Securities  Act of 1933, as
amended, and the regulations thereunder.  Certificates evidencing the shares may
be required to bear a restrictive  legend. A stop transfer order may be required
to be placed with the  transfer  agent,  and the  Company  may require  that the
Participant  or such other person agree that any sale of the shares will be made
only  on one or more  specified  stock  exchanges  or in such  other  manner  as
permitted by the Committee.

The  Participant  shall notify the Company when any  disposition  of the shares,
whether by sale,  gift or  otherwise,  is made.  The Company  shall use its best
efforts to effect any such compliance and listing,  and the Participant or other
person  shall  take any  action  reasonably  requested  by the  Company  in such
connection.

4.8 Limitations on Incentive Stock Options.  (a) The aggregate Fair Market Value
(determined  at the time the Option is  granted)  of the Stock  with  respect to
which  Incentive  Stock  Options  are  exercisable  for  the  first  time  by  a
Participant  during any  calendar  year  (under  all plans of the  Participant's
employer  corporation  and its parent  and  subsidiary  corporations)  shall not
exceed  $100,000.  (b) An  Incentive  Stock  Option  shall not be granted to any
Officer or Director who, at the time of grant,  owns stock  possessing more than
ten percent of the total  combined  voting  power of all classes of stock of the
Company or any Subsidiary.

(c) No Incentive  Stock Option may be  exercisable  more than three months after
termination of the Participant's employment with the Company or with a parent or
Subsidiary  of the  Company,  except that where such  employment  is  terminated
because  of  permanent  and total  disability,  within  the  meaning  of Section
22(e)(3) of the  Internal  Revenue  Code of 1986  ("Permanent  Disability"),  or
death, such period may be one year.

4.9 Termination of Service. Except as otherwise provided in this Plan, or in the
applicable Stock Option Agreement,  if the service of a Participant (i.e., as an
officer, director or employee of the Company or a Subsidiary) terminates for any
reason other than death,  permanent disability or retirement with the consent of
the  Company,  all  Options  held by the  Participant  shall  expire and may not
thereafter be exercised.  For purposes of this section,  the employment or other
service  in  respect  to  Options  held by a  Participant  shall be  treated  as
continuing in tact while the  participant is on military  leave,  sick leave, or
other  bona  fide  leave of  absence  (such  as  temporary  employment  with the
Government)  if the period of such leave does not exceed 90 days, or, if longer,
so long as the  Participant's  right to reestablish his service with the Company
is  guaranteed  either by  statute  or by  contract.  Where the  period of leave
exceeds 90 days and where the Participant's  right to reestablish his service is
not  guaranteed  by statute or by contract,  his service shall be deemed to have
terminated  on the  ninety-first  day of  such  leave.  Anything  herein  to the
contrary   notwithstanding  and  unless  the  Stock  Option  Agreement  provides
otherwise, if the service of a Participant terminates more than four years after
the  grant  of the  Option,  other  than due to a  termination  for  Cause,  the
Participant may exercise such Option within 30 days of such termination.  Except
as so  exercised,  such Option  shall  expire at the end of such  period.  In no
event,  however,  may any Option be exercised  after the  expiration of ten (10)
years from the date of grant of such Option.

For the purpose of the Plan,  termination  for Cause shall mean (i)  termination
due to (a) willful or gross  neglect of duties or (b) willful  misconduct in the
performance  of such duties,  so as to cause material harm to the Company or any
Subsidiary as determined by the Board,  (ii)  termination due to the Participant
committing fraud,  misappropriation or embezzlement in the performance of his or
her duties or (iii) termination due to the Participant  committing any felony of
which he or she is  convicted  and  which,  as  determined  in good faith by the
Board,  constitutes a crime  involving  moral  turpitude and results in material
harm to the Company or a Subsidiary.

4.10  Death.  Except  as  otherwise  provided  in the  applicable  Stock  Option
Agreement,  if a  Participant  dies  at a time  when  his  Option  is not  fully
exercised,  then at any time or times within such period after his death, not to
exceed 12 months, as may be provided in the Stock Option Agreement,  such Option
may be  exercised  as to any or all of the  shares  which  the  Participant  was
entitled to purchase  under the Option  immediately  prior to his death,  by his
executor  or  administrator  or the  person  or  persons  to whom the  Option is
transferred by will or the applicable  laws of descent and  distribution.  In no
event,  however,  may any Option be exercised  after the  expiration of ten (10)
years from the date of grant of such Option.

4.11  Retirement or Permanent  Disability.  Except as otherwise  provided in the
applicable Stock Option  Agreement,  if a Participant  retires from service with
the consent of the Company, or suffers Permanent  Disability,  at a time when he
or she is entitled to exercise an Option, then at any time or times within three
years after his or her  termination  of service  because of such  retirement  or
Permanent  Disability the  Participant may exercise such Option as to all or any
of the  shares  which  he or she was  entitled  to  purchase  under  the  Option
immediately prior to such termination. Except as so exercised, such Option shall
expire  at the end of such  period.  In no  event,  however,  may any  Option be
exercised  after the expiration of ten (10) years from the date of grant of such
Option.

The Committee shall have authority to determine whether or not a Participant has
retired from service or has suffered Permanent Disability, and its determination
shall be binding on all concerned.  In the sole  discretion of the Committee,  a
transfer of service to an affiliate of the Company other than a Subsidiary  (the
latter type of transfer not  constituting  a termination of service for purposes
of the Plan) may be deemed to be a  retirement  from service with the consent of
the Company so as to entitle the  Participant  to exercise the Option  within 90
days after such transfer.

4.12 Stockholder Rights and Privileges.  A Participant shall have no rights as a
stockholder with respect to any Stock covered by an Option until the issuance of
a stock certificate to the Participant representing such Stock.

4.13  Award of SARs.  (a) At any time  prior to six  months  before an  Option's
expiration  date,  the Committee may award to the  Participant an SAR related to
the Option.

(b) The SAR  shall  represent  the right to  receive  payment  of an amount  not
greater than the amount,  if any, by which the Fair Market Value of the Stock on
the trading day  immediately  preceding  the date of exercise of the SAR exceeds
the Option Price.

(c) SARs  awarded  under the Plan shall be  evidenced by either the Stock Option
Agreement or a separate agreement between the Company and the Participant.

(d) An SAR shall be exercisable only at the same time and to the same extent and
subject to the same  conditions as the Option  related  thereto is  exercisable,
except that the Committee may prescribe additional conditions and limitations on
the exercise of any SAR, including a maximum appreciation value. An SAR shall be
transferable  only when the related Option is  transferable,  and under the same
conditions.  The exercise of an SAR shall cancel the related Option. SARs may be
exercised  only when the Fair  Market  Value of a share of Stock  subject to the
related Option  exceeds the Option Price.  Such value shall be determined in the
manner specified in Section 4.13(b).

(e) An SAR shall be  exercisable  only by written notice to the Company and only
to the extent that the related Option is exercisable.  However,  an SAR shall in
no event be  exercisable  during the first six months of its term  except in the
event  of  death  or  Permanent  Disability  of  the  Participant  prior  to the
expiration of such six-month period.

(f) All SARs shall  automatically  be exercised on the last trading day prior to
the  expiration of the related  Option,  so long as the Fair Market Value of the
Stock at the time of exercise exceeds the Option Price, unless prior to such day
the holder instructs the Company otherwise in writing.

(g) Payment of the amount to which a  Participant  is entitled upon the exercise
of an SAR shall be made in cash,  Company stock, or partly in cash and partly in
Company stock, as the Committee shall determine at the time of the Award. To the
extent  that  payment is made in Company  stock,  the shares  shall be valued at
their fair market value, as determined by the Committee.

(h) At any time  when a  Participant  is,  in the  judgment  of  counsel  to the
Company,  subject  to  Section 16 of the  Securities  Exchange  Act of 1934 with
respect to any equity securities of the Company:

                           (i) any election by such  Participant to receive cash
         in whole or in part  upon the  exercise  of such SAR shall be made only
         during the period  beginning on the third  business day  following  the
         date of release by the  Company for  publication  of any  quarterly  or
         annual  summary  statement  of its sales and earnings and ending on the
         twelfth business day following such date of release, and

                           (ii) in the event the  Committee  has not  determined
         the form in which such SAR will be paid (i.e.,  cash, shares of Company
         stock, or any combination thereof), any election to exercise such right
         in whole or in part for cash shall be subject to the subsequent consent
         thereto,  or  disapproval   thereof,  by  the  Committee  in  its  sole
         discretion.

(i) Each SAR shall expire on a date  determined  by the Committee at the time of
Award, or, if later, upon the termination of the related Option.


                                   ARTICLE V


                            MISCELLANEOUS PROVISIONS


5.1  Nontransferability.  No Award under the Plan shall be  transferable  by the
Participant  other than by will or the laws of  descent  and  distribution.  All
Awards  shall be  exercisable  during the  Participant's  lifetime  only by such
Participant  or his  Personal  Representative.  Any  transfer  contrary  to this
Section 5.1 will nullify the Award.

5.2      Amendments.  The Committee may at any time  discontinue  granting 
 Awards under the Plan. The Board may at any time amend



the  Plan or amend any outstanding  Option for the purpose of
satisfying the  requirements of any changes in applicable laws or regulations or
for any other purpose  which may at the time be permitted by law;  provided that
no such amendment  shall result in Rule 16b-3 under the Securities  Exchange Act
of 1934, as amended,  becoming  inapplicable to any Options.  No amendment shall
adversely  affect  the right of any  Participant  under  any  Award  theretofore
granted to him or her except upon his or her written consent to such amendment.

5.3  Termination.  The Board  may  terminate  the Plan at any time  prior to its
scheduled  expiration date but no such  termination  shall adversely  affect the
rights of any Participant under any Award theretofore granted without his or her
written consent.

5.4 Nonuniform  Determinations.  The Committee's  determinations under the Plan,
including without limitation (i) the determination of the Officers and Directors
to receive Awards,  (ii) the form,  amount and timing of such Awards,  (iii) the
terms and provisions of such Awards and (iv) the Agreements evidencing the same,
need  not be  uniform  and may be  made by it  selectively  among  Officers  and
Directors  who receive,  or who are eligible to receive,  Awards under the Plan,
whether or not such Officers or Directors are similarly situated.

5.5 No Right to Employment.  Neither the action of the Board in establishing the
Plan, nor any action taken by the Committee under the Plan, nor any provision of
the Plan, shall be construed as giving to any person the right to be retained in
the employ, or as an officer or director, of the Company or any Subsidiary.

5.6  Changes  in  Stock.  In the  event  of a  stock  dividend,  split-up,  or a
combination  of shares,  recapitalization  or merger in which the Company is the
surviving  corporation or other similar capital  change,  the number and kind of
shares of stock or  securities  of the  Company to be subject to the Plan and to
Options or SARs then outstanding or to be granted thereunder, the maximum number
of shares of stock or  security  which may be issued on the  exercise of Options
granted under the Plan, the Option Price and other relevant  provisions shall be
appropriately adjusted by the Board, whose determination shall be binding on all
persons. In the event of a consolidation or a merger in which the Company is not
the surviving corporation,  or any other merger in which the shareholders of the
Company  exchange  their  shares of stock in the  Company  for stock of  another
corporation,  or in the event of complete  liquidation of the Company, or in the
case of a tender  offer  accepted  by the Board of  Directors,  all  outstanding
Options and SARs shall thereupon  terminate,  provided that the Board may, prior
to the effective date of any such  consolidation or merger,  either (i) make all
outstanding Options and SARs immediately exercisable or (ii) arrange to have the
surviving corporation grant to the Participants  replacement Options and SARs on
terms which the Board shall determine to be fair and reasonable.
