Foster Company (the "Company") adopted the SUPPLEMENTAL EXECUTIVE RETIREMENT
PLAN (the "Plan") effective as of January 1, 1994. The Plan was established to
pay supplemental benefits to certain executive employees who qualify for
benefits under the Voluntary Investment Plan (the "VIP').

                  WHEREAS, the Plan is unfunded, and the Company will make the
Plan benefit payments solely from its general assets on a current disbursement
basis.

                  WHEREAS, the provisions of this Plan shall apply only to
employees who are employed by the Company on or after January 1, 1994.

                  WHEREAS, the principal objective of this Plan is to ensure the
payment of a competitive level of benefits in order to attract, retain and
motivate selected executives. This Plan was designed to provide retirement
benefits lost due to Internal Revenue Code ("IRC") Sections 401(a) 17, 402(g),
and 401(a)(4), as well as any other code section(s) limiting the amount the
Company can contribute under the VIP.

                  WHEREAS, the Plan originally became effective January 1, 1994.
Any employee whose employment terminated prior to January 1, 1994 shall have no
rights under this Plan.

                  WHEREAS, effective January 1, 2005, the Plan was amended and
restated to comply with Internal Revenue Code Section 409A.

employment.

3.3  The beneficiary of a Participant who dies while a Participant shall be
eligible to receive such Participant's retirement benefit the first day of the
second month following the date of such Participant's death, unless the
Committee is not timely made aware of such death or otherwise has good reason to

                                   SECTION IV


                    AMOUNT AND PAYMENT OF RETIREMENT BENEFIT

4.1      The retirement benefit payable at retirement shall be the sum of (a)
minus (b), plus (c) below.

  (a)        For each year or portion of a year in which the employee is a
             Participant the Company shall calculate the amount which the
             Company would have contributed under the VIP for the benefit
             of such Participant but for IRC limits.

  (b)        For each year or portion of a year in which the employee is a
             Participant the Company shall calculate the amount which is
             the greater of

    (i)        The Company's actual contributions to the VIP for the benefit
               of such Participant, or

    (ii)       The amount which the Company would have contributed to the VIP
               for the benefit of such Participant if the Participant had
               made all permissible elective contributions to the VIP, but
               subject to IRC limits.

  (c)        The Company shall apply interest each December 31 to the
             amount of benefit, determined by subtracting (b) from (a), as
             well as to any previous year's accumulated balance under this
             Plan, at the greater of

    (i)        The calendar year's rate of return of Fidelity's Managed Income
               Portfolio as of December 31 of such year, or

    (ii)       A one-year annualized Treasury Bill interest rate as reported
               for the last Friday each year.

4.2      The Committee will determine in it's sole discretion whether benefit
payment(s) to the Participant will be made in 1) a single lump sum payment, or
2) in five annual installments commencing on the dates referred to in Section
III.



                                    SECTION V

                                  MISCELLANEOUS

5.1   Amendments to this Plan shall be made by resolution of the Board of
Directors of the Company adopted in accordance with the by-laws of the Company
and applicable corporation law. Alternatively, any one or more officers of the
Company may adopt amendments if authority to amend the Plan has been delegated
to them by the Board of Directors in accordance with the by-laws of the Company
and applicable corporation law. A delegation may be general (by way of
describing the general duties and responsibilities of the officers) or specific
with regard to employee benefit plans such as this and is not valid merely
because it was made before this Plan was established. An officer exercising
delegated authority to amend the Plan shall memorialize that exercise in writing
signed by the officer.

5.2   Nothing contained herein will confer upon any Participant the right to be
retained in the service of the Company, nor will it interfere with the right of
the Company to discharge or otherwise deal with Participant(s) without regard to
the existence of this Plan.

5.3   This plan is unfunded and has no assets. There is no trust or insurance.
All payments made under the Plan are made from the general assets of the
Company. Participation in the Plan gives the employee nothing more than the
Company's contractual promise to pay deferred compensation when due in
accordance with the terms of this Plan.

5.4   The Company is not required to segregate, maintain or invest any portion
of its assets by reason of its contractual commitment to pay deferred
compensation under this Plan. If the Company nevertheless chooses to establish a
reserve, such reserve remains an asset of the Company in which no participating
employee has any right, title or interest. Employees entitled to deferred
compensation under this Plan have the status of general unsecured creditors of
the Company.

5.5   If a Participant is discharged by the Company for cause (conduct that is
injurious to the Company, or conduct which intentionally violates either the
Company's written policies or the reasonable directives of the Company's Chief
Executive Officer; or the commission of a felony) such Participant's rights to
any benefit under this Plan shall be forfeited.

5.6   If the Committee determines that any Participant is engaged in any trade,
profession or business which is, or likely to be, detrimental to the best
interests of the Company, or if the Committee determines that such Participant
has used or is using trade secrets or other confidential information gained
while in the employ of the Company, the Committee may, upon written notice to
the Participant, suspend or forfeit the Participant(s) right to any benefit
under this Plan.

5.7   No benefits are payable under this Plan if a Participant terminates his
employment for any reason other than those specifically referred to in Section
III.

5.8   The Plan Administrator has all rights, duties and powers necessary or
appropriate for the administration of the Plan.


5.9   Subject to Internal Revenue Code Sections 409A(a)(3) and (4) which address
the timing, form and restrictions on acceleration rules, the Plan Administrator
shall have and shall exercise complete discretionary authority to construe,
interpret and apply all of the terms of the Plan, including all matters relating
to eligibility for benefits, amount, time or form of payment, and any disputed
or allegedly doubtful terms. In exercising such discretion, the Plan
Administrator shall give controlling weight to the intent of the Sponsor of the
Plan.

5.10   All decisions of the Plan Administrator in the exercise of its authority
under the Plan shall be binding on the Plan, the Plan Sponsor and all
participants and beneficiaries if not appealed in accordance with the appeal
procedure. All decisions of the Plan Administrator on appeal shall be final and
binding on the Plan, the Plan Sponsor and all participants and beneficiaries.

5.11   Each Participant shall receive a copy of this Plan and the Committee will
make available for each Participant a copy of any rules and regulations used by
the Committee administering the Plan.

5.12   Each Participant will be provided an annual summary of the amount of
retirement benefit allocated under the Plan.

5.13   This Plan is established under and will be construed according to the
laws of the Commonwealth of Pennsylvania to the extent not pre-empted by federal
law.



                                   SECTION VI

                          CLAIMS AND APPEAL PROCEDURES

6.1   There should be no need to file a claim for benefits. The Company is
expected to pay each participating employee automatically, in accordance with
the terms of this Plan. Nevertheless, a participating employee may claim
benefits under this plan by filing a written claim with the Plan Administrator.

6.2   As required by the Internal Revenue Service, a participating employee's
right to benefits under this Plan is not subject in any manner to anticipation,
alienation, sale, transfer, assignment, pledge, encumbrance, attachment or
garnishment by creditors of the employee or the employee's beneficiary.

6.3   If a claim is denied and the employee disagrees and wants to pursue the
matter, the employee must file an appeal in accordance with the following
procedure. An employee cannot take any other steps unless and until the appeal
procedure has been exhausted. For example, if a claim is denied and the employee
does not use the appeal procedure, the denial is conclusive and cannot be
challenged, even in court.

6.4   An appeal is filed by writing to the Plan Administrator stating the
reasons why the employee disagrees with the denial. An appeal must be made
within 60 days after the claim was denied. In the appeal process, the employee
has the right to review the pertinent documents, to be represented by anyone
else, including a lawyer, and to present evidence and arguments in support of
the appeal.

6.5   The Plan Administrator will issue a written decision on the appeal within
60 days. The Plan Administrator may, in its sole discretion, decide to hold a
hearing, in which case it will issue its decision within 120 days. The decision
will explain the reasoning of the Plan Administrator and refer to the specific
provisions of this Plan on which the decision is based.
