Exhibit 10.1

AGREEMENT

This AGREEMENT, dated as of February 12, 2016, is made and entered into by L. B.
Foster Company, a Pennsylvania corporation (“L. B. Foster” or the “Company”) and
each of the persons set forth on the signature page hereto (each, an “Investor”
and collectively, the “Investor Group”) which presently are or may be deemed to
be members of a “group” with respect to the common stock of the Company, par
value $0.01 per share (the “Common Stock”), pursuant to Rule 13d-5 promulgated
by the U.S. Securities and Exchange Commission (the “SEC”) under the Securities
Exchange Act of 1934, as amended (the “Exchange Act”);

WHEREAS, the Company and the Investor Group have engaged in discussions
regarding the Company’s board composition and its business, financial
performance, and strategic plans;

WHEREAS, the Investor Group is deemed to beneficially own shares of the Common
Stock totaling, in the aggregate, 986,136 shares or approximately nine and six
tenths percent (9.6%) of the Common Stock outstanding as of January [•], 2016;
and

WHEREAS, the Company and the Investor Group believe that the best interests of
the Company and its shareholders would be served at this time by, among other
things, agreeing to appoint, at the request and recommendation of the Investor
Group, Mr. Bradley S. Vizi (the “New Director”) to the Company’s Board of
Directors (the “Board”) and agreeing to the other covenants and agreements
contained herein.

NOW, THEREFORE, in consideration of the foregoing premises and the mutual
covenants and agreements contained herein, and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the
parties hereto, intending to be legally bound hereby, agree as follows:

1. Board Matters; Board Appointments; Board Policies Procedures.

(a) Board Matters. Prior to the execution of this Agreement (i) the Nomination
and Governance Committee of the Board (the “Nominating Committee”) has reviewed
and approved the qualifications of the New Director to serve as a member of the
Board and (ii) the Board has determined that the New Director is “independent”
as defined by the listing standards of NASDAQ. The Company agrees that the Board
and all applicable committees of the Board shall take all necessary actions to
(i) cause the Board to increase the size of its membership by one effective
immediately following the execution of this Agreement; (ii) appoint, with such
appointment effective immediately after the execution of this Agreement, the New
Director as a director of the Company with a term expiring at the Company’s 2016
Annual Meeting of Shareholders (the “2016 Annual Meeting”); (iii) nominate the
New Director as a candidate for reelection to the Board at the 2016 Annual
Meeting; and (iv) cause the Board to decrease the size of its membership by

--------------------------------------------------------------------------------

one effective as of certification of the shareholder vote with respect to the
2016 Annual Meeting. At the 2016 Annual Meeting and, if the Standstill Period
(as defined below) has not then expired, the Company’s 2017 Annual Meeting of
Shareholders (the “2017 Annual Meeting”), the Company agrees to recommend,
support and solicit proxies for the election of the New Director in the same
manner as the Company has supported its nominees up for election at prior annual
meetings of shareholders at which the election of directors was uncontested. The
Company agrees that the New Director shall receive (i) the same benefits of
director and officer insurance, and any indemnity and exculpation arrangements
available generally to the directors on the Board (ii) the same compensation for
his service as a director as the compensation received by other non-management
directors on the Board, and (iii) such other benefits on the same basis as all
other non-management directors on the Board, including, without limitation,
having the Company (or legal counsel) prepare and file with the SEC, at the
Company’s expense, any Forms 3, 4 and 5 under Section 16 of the Exchange Act
that are required to be filed by each director of the Company. The Company
agrees that the size of the Board shall not be increased beyond nine (9) members
throughout the Standstill Period without the consent of the New Director.

(b) Committees of the Board. The Company agrees that, concurrent with the New
Director’s appointment to the Board, the New Director shall be appointed as a
member of each of the Compensation Committee and of the Nominating Committee,
provided that the New Director is and continues to remain eligible to serve in
such capacity pursuant to applicable law and the rules of NASDAQ, and shall be
considered along with all other Board members for Board committee assignments in
connection with the Board’s annual review of committee composition or upon the
formation of any special committee of the Board.

(c) Board Policies and Procedures. The New Director understands and acknowledges
that all members of the Board, including the New Director, are required to
comply with all policies, processes, procedures, codes, rules, standards, and
guidelines applicable to members of the Board, including the Company’s Corporate
Governance Guidelines, Legal and Ethical Conduct Policy, and policies on insider
trading, stock ownership, public disclosures and confidentiality, copies of
which the New Director acknowledges receiving prior to the execution of this
Agreement, and the New Director agrees to strictly preserve the confidentiality
of Company business and information, including the discussion of any matters
considered in meetings of the Board or Board committees whether or not the
matters relate to material non-public information; provided, however, that,
solely during the Standstill Period, the New Director may disclose certain
Company information to certain persons in the Investor Group in accordance with
a confidentiality agreement dated the date of this Agreement (the
“Confidentiality Agreement”). The New Director shall provide the Company with
such information as reasonably requested from all members of the Board as is
required to be disclosed under applicable law or stock exchange regulations, in
each case as promptly as necessary to enable the timely filing of the Company’s
proxy statement and other periodic reports with the SEC.

--------------------------------------------------------------------------------

(d) Resignation. The New Director and the Investors agree that the New Director
will resign (and is deemed hereby to have irrevocably agreed to so resign) and
the Company’s obligations under this Section 1 shall terminate effective
immediately upon such time as any Investor or any Affiliate (as defined below)
or Associate (as defined below) thereof submits a notice of a nomination of
directors for election to the Board at the 2016 Annual Meeting or, if the
Standstill Period (as defined below) has not then expired, the 2017 Annual
Meeting, or any Investor or the New Director is otherwise found by a court of
competent jurisdiction to have violated Section 3 hereof during the Standstill
Period. In addition, the Company’s obligations under this Section 1 shall
terminate immediately, and the New Director or any replacement director
appointed in accordance with Section 1(e) below shall promptly offer to resign
from the Board (and, if requested by the Company, promptly deliver his or her
written resignation to the Board (which shall provide for his or her immediate
resignation) it being understood that it shall be in the Board’s sole discretion
whether to accept or reject such resignation) if the Investor Group,
collectively, ceases to beneficially own at least four and seven tenths percent
(4.7%) of the then-outstanding Common Stock. The Investors agree to use
commercially reasonable efforts to cause the New Director or any replacement
director appointed in accordance with Section 1(e) below to resign from the
Board if such person fails to resign if and when requested pursuant to this
clause (d). In furtherance of the foregoing, the New Director, as a condition to
being appointed to the Board pursuant hereto, shall execute an irrevocable
advance letter of resignation in the form attached hereto as Exhibit A. The
percentage threshold set forth in this clause (d) shall not be deemed
unsatisfied to the extent a failure to maintain the specified ownership
thresholds is caused by share issuances, stock splits, reclassifications,
combinations or similar actions by the Company that increase the number of
outstanding shares of Common Stock.

(e) Replacements. The Company agrees that if the New Director is, other than as
a result of not being nominated for election at the 2017 Annual Meeting or
ceasing to serve as a director under the circumstances contemplated by
Section 1(d) hereof, unable to serve as a director for any reason, resigns, or
is removed as a director prior to the end of the term of office set forth above
during the Standstill Period (as defined below), then the Investor Group shall
have the ability to recommend a substitute person, provided that any such
substitute person so recommended shall be reasonably acceptable to the
Nominating Committee after exercising its fiduciary duties in good faith and
shall qualify as “independent” pursuant to NASDAQ’s listing standards and have
the relevant financial and business experience to fill the resulting vacancy.
The Nominating Committee shall make its determination and recommendation
regarding whether such person is acceptable and meets the foregoing criteria
within twenty (20) business days after representatives of the Board have
conducted customary in-person interview(s) of such director candidate (such
determination not to be unreasonably withheld). The Company shall use its
reasonable best efforts to conduct any interview(s) contemplated by this section
as promptly as practicable, but in any case, assuming reasonable availability of
the proposed director candidate, within twenty (20) business days after the
Investor Group’s submission of such director candidate’s credentials, including,
but not limited to, a completed copy of the Company’s standard director and
officer questionnaire and the Investors agreeing to

--------------------------------------------------------------------------------

make any such person available for a customary in-person interview with the
Nominating Committee and other representatives of the Board as determined by the
Board. In the event that the Nominating Committee does not accept a substitute
person so recommended, then the Investor Group shall have the right to recommend
an additional substitute person for consideration by the Nominating Committee in
accordance with the procedures described above. Upon acceptance of a replacement
director candidate by the Nominating Committee, and the agreement by such
replacement director candidate that such candidate will resign (and is deemed to
have irrevocably agreed to so resign) from the Board effective immediately upon
such time as any Investor submits a notice of director nomination for election
to the Board at the 2016 Annual Meeting or the 2017 Annual Meeting, or any
Investor or the New Director is otherwise found by a court of competent
jurisdiction to have violated Section 3 hereof during the Standstill Period, the
Board will take such actions as to appoint such replacement director candidate
to the Board no later than twenty (20) business days after the Nominating
Committee’s recommendation; provided, however, that if the Board does not elect
such replacement director candidate to the Board pursuant to this Section 1(e),
the Company and the Investor Group shall continue to follow the procedures of
this Section 1(e) until a replacement director candidate is elected to the
Board. Any replacement director appointed to the Board in accordance with this
Section 1(e) shall be appointed to any applicable committees of the Board of
which the replaced director was a member immediately prior to such director’s
resignation or removal and will succeed to all of the rights and privileges of,
and will be legally bound by the terms and conditions applicable to, the New
Director under this Agreement and, prior to being appointed to the Board, the
replacement director candidate will be required to execute a document confirming
that he or she will be so legally bound in his or her personal capacity,
provided, however, that, for the avoidance of doubt, the replacement director
candidate will not be subject to Sections 3, 4 and 7(a) of this Agreement.
Notwithstanding the foregoing, in the event the replacement director is found by
the Nominating Committee, acting in good faith and in exercise of its fiduciary
duty, to be an Affiliate or Associate of any Investor, or to be employed by or a
member of, or directly or indirectly affiliated with, controlled by, or under
common control of any Investor such affiliated replacement director additionally
will be legally bound by Sections 3, 4, and 7(a) hereof. Thereafter, the term
“New Director” as used herein shall be deemed to refer to such replacement
director.

2. 2016 Annual Meeting. At the 2016 Annual Meeting, the 2017 Annual Meeting if
the Standstill Period (as defined below) has not then expired, and at each
special meeting of shareholders held prior to the expiration of the Standstill
Period, each of the Investors agrees to (i) appear at such shareholders’ meeting
or otherwise cause all shares of Common Stock beneficially owned by each
Investor and their respective Affiliates and Associates to be counted as present
thereat for purposes of establishing a quorum, (ii) vote, or cause to be voted,
all shares of Common Stock beneficially owned by each Investor and their
respective Affiliates and Associates on the Company’s proxy card or voting
instruction form in favor of (a) each of the directors nominated by the Board
and recommended by the Board in the election of directors (and not in favor of
any other nominees to serve on the Board), and (b) except in connection with any
Opposition Matter (as defined below) or any ISS or Glass Lewis Voting
Recommendation (as defined below), each of the shareholder proposals listed on
the

--------------------------------------------------------------------------------

Company’s proxy card or voting instruction form as identified in the Company’s
proxy statement in accordance with the Board’s recommendations, including in
favor of all other matters recommended for shareholder approval by the Board,
and (iii) not execute any proxy card or voting instruction form in respect of
such shareholders’ meeting other than the proxy card and related voting
instruction form being solicited by or on behalf of the Board; provided,
however, in the event that Institutional Shareholders Services (“ISS”) or Glass
Lewis & Co., LLC (“Glass Lewis”) recommends otherwise with respect to any
proposal (other than the election of directors), each of the Investors shall be
permitted to vote in accordance with the ISS or Glass Lewis voting
recommendation (“ISS or Glass Lewis Voting Recommendation”) but, notwithstanding
such recommendation, only on the proxy card and related voting instruction form
being solicited by or on behalf of the Board even if ISS or Glass Lewis
recommended that the Investors vote on another proxy card or voting instruction
form. No later than five (5) business days prior to each such meeting of
shareholders, each Investor shall, and shall cause each of its Associates and
Affiliates to, vote any shares of Common Stock beneficially owned by such
Investors in accordance with this Section 2. No Investor nor any of its
Affiliates or Associates nor any person under its direction or control shall
take any position, make any statement or take any action inconsistent with the
foregoing. For purposes of this Agreement, “Opposition Matter” shall mean any of
the following transactions or events, but only to the extent submitted by the
Board to the Company’s stockholders for approval: the sale or transfer of all or
substantially all of the Company’s assets in one or a series of transactions;
the sale or transfer of a majority of the outstanding shares of Common Stock
(through a merger, stock purchase, or otherwise); any merger, consolidation,
acquisition of control or other business combination; any tender or exchange
offer; any dissolution, liquidation, or reorganization; any changes in the
Company’s capital structure (including the issuance of more than 20% of the
Company’s then outstanding shares of Common Stock); change in control
transactions; or financings requiring approval by NASDAQ’s shareholder approval
rules; in each case that has been approved by the Board but voted against by the
New Director.

expiration of the Standstill Period (as defined below), without the prior
consent of the majority of the Board specifically expressed in a written

its shareholders (it being understood and agreed that neither the Investors nor
any of their Affiliates or Associates shall seek to do indirectly through the
New Director anything that would be prohibited if done by any of the Investors

not prevent the Investor Group from freely voting its shares of Common Stock

the respective meanings set forth in Rule 12b-2 promulgated by the SEC under the

Concert” with another person if such person knowingly acts (whether or not

in concert with such other person to change or influence the composition of the
Board of Directors, the strategic direction of the Company, the governance or
management of the Company, the sale or purchase of any assets of or by the
Company, or the control of the Company or as a participant in any solicitation,
campaign, initiative, negotiations, engagement, or transaction, whether
intended, proposed, pending, or completed, having that purpose or effect, where
(i) each person is conscious of the other person’s conduct and this awareness is
an element in their decision-making processes and (ii) at least one additional
factor would support a reasonable inference that such persons intended to act in
concert, which such additional factors may include, without limitation,
exchanging information, or making or soliciting invitations to act in concert;

officer or director of the Company acting solely in such capacities.

(f) Notwithstanding anything contained in this Agreement to the contrary:

termination of such sections; and

(ii) For purposes of this Agreement, a “Change of Control” transaction shall be
deemed to have taken place if (1) any person is or becomes a beneficial owner,
directly or indirectly, of securities of the Company representing more than 50%

equity securities or (2) the Company enters into a stock-for-stock transaction

time or both could become a default) under or pursuant to, or result in the loss

L.B. FOSTER APPOINTS NEW INDEPENDENT BOARD MEMBER

PITTSBURGH, PA, February 17, 2016 – L.B. Foster Company (NASDAQ: FSTR), today
announced that it appointed Bradley S. Vizi to its Board of Directors, effective
February 12, 2016. Mr. Vizi is also being appointed to the Compensation
Committee and the Corporate Nomination and Governance Committee of the L.B.
Foster Board. With the addition of Mr. Vizi, the L.B. Foster Board will comprise
nine directors, eight of whom are independent, and will reduce to eight
directors at the 2016 Annual Meeting of Shareholders due to the retirement of an
incumbent director under the provisions of the Company’s Corporate Governance
Guidelines.

Mr. Vizi, 32, is a founder of, and a Managing Director at, Legion Partners Asset
Management, LLC, which, along with its affiliates, is a large shareholder of the
Company (collectively, “Legion Partners”). Prior to founding Legion Partners in
2011, Mr. Vizi was an investment professional for Shamrock Capital Advisors, the
alternative investment vehicle of the Disney Family. Mr. Vizi graduated from the
Wharton School at the University of Pennsylvania with a Bachelor of Science
degree in Economics and is a CFA. Since 2013, Mr. Vizi has served on the Board
of Directors of publicly-held RCM Technologies, Inc. and currently serves as
Chairman of the Board.

“We are pleased to welcome Brad to the L. B. Foster Board of Directors,” said
Lee Foster, Chairman of the Board. “We believe Brad’s investment background and
public company Board experience will be beneficial to L.B. Foster and our
shareholders as we continue to execute on our initiatives for creating
shareholder value. I am particularly delighted with the confidence that Brad has
in the Company and our shared vision of the future.”

Mr. Vizi stated, “I am honored to serve on the board of a global company with
such high quality solutions that improve transportation and energy
infrastructure. My recent conversations with L.B. Foster’s Board and senior
management team have been encouraging and have only validated our beliefs about
the quality and character of L.B. Foster’s Board and management team and the
path that lies ahead. I believe we share many of the same priorities and are
aligned in our commitment to creating value for all L.B. Foster shareholders. I
look forward to working collaboratively with the rest of the L.B. Foster Board
to build upon the solid foundation in place and position the Company to take
advantage of opportunities to create value and reward shareholders.”

Under the terms of an agreement between the Company and Legion Partners
regarding the appointment of Mr. Vizi, Legion Partners has agreed to vote their
shares in favor of the election of L.B. Foster’s slate of directors at L.B.
Foster’s 2016 Annual Meeting and to abide by certain standstill provisions.

The complete agreement between L.B. Foster and Legion Partners will be filed in
a Current Report on Form 8-K with the Securities and Exchange Commission.
