ELIGIBILITY

 

2.1 Eligibility.

 

  (a) The Participant shall be eligible to receive the full amount of the
Benefit designated in this Agreement if the Participant has reached the age of
fifty-six (56) and been in the Program for ten (10) years. The date of entry
into the Program will be the date the Parties hereto entered into an Agreement
establishing the Participant’s Benefit amount.

 

2

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

  (b) If Participant has reached age 56 for vesting in the Benefit but has not
been in the Program the requisite ten (10) years and decides to Retire before
attaining 10 years in the Program, the Participant will receive an annual
payment on a pro rata basis determined by Participant’s tenure in the 10 year
vesting requirement. [By way of example only, a Participant Retiring at age
fifty-eight (58) and having only six (6) years in the Program would receive 60%
of the annual Benefit provide in this Agreement.]

 

  (c) Annual Benefit amounts while Participant is in the Program and before
Retirement will increase by the 3% COLA each year, starting with the first
anniversary of this agreement.

 

2.2 Amount of Benefit. The amount of Participant’s Annual Benefit payable under
this Agreement shall be Forty Thousand Dollars ($40,000) payable in monthly
installments commencing on the Benefit Commencement Date for a period often
(10) years. The Corporation shall withhold applicable federal, state and local
taxes from the amounts due pursuant to the payment of any Benefit hereunder to
the extent such withholding is required by reason of such laws.

 

2.3 Forfeiture.

 

  (a) To be eligible to receive the Benefit once the vesting requirements have
been met and Participant has Retired, the Participant must not act in any
capacity for any business enterprise which competes in a substantial degree with
the Company or any subsidiary or affiliate thereof, nor engage in any activity
which involves substantial competition with the Company for a period of one
(1) year after Retiring from the Company without the consent of the Company.
Such consent shall not be withheld unless Participant’s competitive activities
on behalf of another employer could be reasonably expected to significantly
impact in an adverse manner the operations of the Division in which the
Participant had been assigned prior to Retirement.

Participant acknowledges that his/her services under this Agreement are of a
special, unique, unusual, extraordinary, and intellectual character, and that a
breach by Participant of this Section 2.3 could cause the Company irreparable
injury and damage and would therefore, cause a breach of this Agreement.

 

  (b) Participant agrees not to reveal to any third party any trade secrets or
other confidential or proprietary information of the Company, including but not
limited to, client lists, operational methods, financial information or other
information the Company generally regards and protects as confidential and
proprietary.

  (c) If Participant should violate subsections (a) and/or (b) above without the
consent of the Company, such Participant’s entire or remaining Benefit payments,
as the case may be, shall be forfeited.

 

  (d) The Corporation shall stop payments to Participant hereunder if
Participant is involved in fraud, or if the Corporation determines that
Participant has been grossly negligent or has been engaged in willful misconduct
in the course of his/her employment. Nothing contained in this Agreement shall
in any way be construed to limit or otherwise waive the legal or equitable
rights or remedies of the Corporation to recoup monies paid hereunder to
Participant if the Corporation determines that it is entitled to such
recoupment.

 

2.4. Disability Benefits.

 

  (a) Disability Before Ten Years Participation. If Participant becomes disabled
or suffers from a disability prior to meeting either the age 56 requirement or
10 years in the Program, he/she shall be entitled to receive a Benefit amount
equal to that which the Participant would have been eligible to receive had
he/she Retired on the same date as the date of determination of the disability.
The Benefit amount shall be calculated according to the provisions of paragraph
2.1(b). Said amount would be payable for ten (10) years commencing upon
Participant’s determination of disability, provided, however, that Participant
must have been in the Program for at least 6 months.

Periods of temporary Disability and leaves of absence granted by the Company
shall not be deemed to interrupt continuous employment.

A Participant shall be deemed Disabled or suffering from a Disability (herein
referred to as “Disability” or “Disabled”) if, as a result of injury, sickness,
or disease, he is prevented from performing all of the material duties of
his/her regularly assigned responsibilities with the Company for a period of
ninety (90) consecutive days or more. The Company shall make the determination
of whether such person is Disabled for purposes of this Agreement.

 

  (b) Disability After Ten Years Participation. If a Participant becomes
disabled or suffers from a disability after meeting the age 56 and 10 year
tenure requirement for receiving his/her designated Benefit hereunder but before
Benefit payments have commenced, the Participant shall be entitled to receive
payments starting immediately for the entire 10-year Benefit period. The annual
amount thereof shall be equal to the annual Benefit Level amount that the
Participant was entitled to receive upon Retirement.

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

2.5 Death Benefits.

 

  (a) Death Before Ten Years Participation. If a Participant’s death occurs
prior to Retirement, his/her Beneficiary shall be entitled to receive a Death
Benefit (hereinafter referred to as the “Death Benefit”) in an amount equal to
that which the Participant would have been eligible to receive had he/she
Retired on the same date as the date of death. The amount would be calculated
according to the provisions of paragraph 2.1(b). Said amount would be payable
for ten (10) years commencing upon Participant’s Death, provided, however, that
Participant must have been in the Program for at least 6 months.

 

  (b) Death After Ten Years Participation. If Participant’s death occurs after
meeting the age 56 and 10-year tenure requirement for receiving his/her
designated Benefit hereunder but before Benefit payments have commenced or
before he has received all payments hereunder, Participant’s Beneficiary shall
be entitled to receive payments starting immediately for the entire Benefit
period. The annual amount thereof shall be equal to the annual Benefit amount
(or Disability) that Participant had been receiving or was entitled to receive.

 

2.6 Suicide Disqualification. Notwithstanding Section 2.4 hereof, no Benefits
shall be payable to a Beneficiary if Participant’s death resulted from suicide
within two (2) years after he/she becomes a Participant.

 

2.7 Designation of Beneficiary. Participant, immediately upon becoming a
Participant, shall designate in writing the Beneficiary who shall receive a
Benefit as a result of his/her death. Participant may change the Beneficiary
from time to time, as his/her discretion, by notifying the Company in writing.

In the event the Beneficiary dies before all Benefit payments to which the
Beneficiary is entitled are made hereunder, the remaining payments shall be paid
to the personal representative of the Beneficiary’s estate in accordance with
applicable state law. If Participant fails to designate a Beneficiary, or if no
Beneficiary survives Participant, the Benefit payments due hereunder shall be
made to the personal representative of Participant’s estate in accordance with
applicable state law.

ARTICLE 3

3.1 In the event Participant (or a Beneficiary) does not receive a distribution
of a Benefit to which he believes he is entitled, he may present a claim to the
Board of Directors of The PBSJ Corporation. The claim must be in writing and
addressed to the Corporation.

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

  The decision of the Board shall be made within sixty (60) days after receipt
of a request for review and shall be communicated in writing to Participant (or
a Beneficiary). Such written notice shall set forth the basis for the Board’s
