<PAGE>

Employee is elected or appointed as an officer or director of the Corporation
during the employment term specified in paragraph 2 hereof, he shall serve in
said capacity or capacities without additional compensation. The Employee will
not be required to perform any services hereunder which will necessitate moving
his residence from Tallahassee, Florida, unless he agrees, in writing, to such
relocation.

         2.  Employment Term. The term of employment of the Employee hereunder
shall commence on the date of execution of this Agreement, and shall continue
until January 1, 2001 or until terminated in accordance with this Agreement.
Upon mutual written agreement of the Employee and the Corporation, the
employment term specified in this paragraph 2 may be shortened or extended for
additional periods on the terms, provisions and conditions set forth herein or
as otherwise mutually acceptable to the Corporation and the Employee.

         3.  Employment Compensation. The Corporation shall pay to the Employee
during the term of employment specified in paragraph 2 hereof, as salary for his
services, the amount of One Hundred Twenty Thousand Dollars ($120,000) per
annum. Such employment compensation shall be payable as prescribed by the
Corporation's regular payroll system but in no event less often than in equal
monthly installments. The employment compensation amount specified in this
paragraph 3 may be adjusted by mutual consent of the Corporation and the
Employee, and any such adjustment shall operate as an automatic amendment of
said employment


                                       3
<PAGE>

compensation amount.

         4.  Consulting. The Corporation acknowledges the valuable business
asset represented by the experience and judgment of the Employee as it has
evolved and continues to mature during the period of the Employee's association
with the Corporation. The Corporation desires to secure the continued
availability of this business acumen as a corporate asset beyond the period of
employment specified in paragraph 2. Accordingly, in order to preserve this
asset to the Corporation, the Employee shall remain reasonably available to
serve the Corporation as a consultant or advisor for a period of five (5) years
commencing on January 1, 2001. During each such year of availability, Employee
agrees to serve as a consultant or advisor to the Corporation for a period of up
to forty-five (45) days upon request by the Corporation and subject to the
conditions specified below. The performance of advisory and consulting services
to and for the corporation, as provided in this paragraph 4, shall be subject to
the following conditions:

             (a) The Employee shall not be required to render consulting or
advisory services during vacation periods or during periods of personal or
family illness or other incapacity.

             (b) To the extent such services are not reasonably required to be
performed at a particular location, they may be performed at such place or
places as the Employee may designate from time to time.

                                       4
<PAGE>

             (c) The Employee shall be entitled to designate up to three
one-month periods (which may or may not be consecutive) during which he shall
not be required to render consulting or advisory services.

             (d) The Employee shall be entitled to at least ten (10) business
days' notice prior to the commencement of any proposed consulting or advisory
assignment.

             (e) The Employee shall be subject to the same confidentiality
requirements as a consultant or advisor as he was during the term of his
employment.

         5.  Consulting Compensation. In consideration of his availability as a
consultant or advisor to the Corporation during the period specified in
paragraph 4, Employee shall receive the amount of Seventy-Five Thousand
Dollars ($75,000) per year (the "Consulting Retainer"). The annual Consulting
Retainer shall constitute payment to Employee for his availability and up to
forty-five (45) days of actual service to the Corporation as a consultant or
advisor during any such year of availability. In the event the Corporation
desires consulting or advisory services from Employee in addition to the
aforementioned forty-five (45) days, such service and the compensation therefor
shall be subject to the mutual agreement of the Corporation and the Employee.
The Consulting Retainer shall be paid whether or not Employee is requested by
the Corporation to provide consulting or advisory services and shall be payable
in a manner consistent with the Corporation's regular payroll system but in no
event less often


                                       5
<PAGE>

than in equal monthly installments. The amount of the Consulting Retainer
payable under this Agreement shall be increased at the end of each calendar year
commencing with the year 1987 and ending with the year preceding the last year
during which consulting payments are made under this Agreement by a percentage
of such amount equal to the lesser of (1) three percent (3%), or (2) the
increase in the national Consumer Price Index ("CPI" as published by the United
States Government for such year. Adjustments shall be effective on January 1
based on the CPI for the prior year computed from December to December. For the
purposes of this Agreement, the CPI referred to shall be all items shown on the
U.S. city average for urban wage earners and clerical workers (including single
workers), all items, groups, subgroups and special groups of items as
promulgated by the Bureau of Labor Statistics of the U.S. Department of Labor.
If the U.S. Department of Labor ceases to publish the above-described CPI, then
such CPI as may be published by such Department most nearly approaching said
discontinued CPI shall be used in making the above adjustments. If the
Department discontinues any such CPI, then such CPI as may be published by
another U.S. Government agency, as most nearly approximates the CPI first above
referred to, shall govern, subject to the application of an appropriate
conversion factor to be furnished by the governmental agency publishing the
adopted CPI.

         6.  Normal Retirement Supplemental Income.

             (a) The Employee is eligible for Normal Retirement


                                       6
<PAGE>

from active and daily employment with the Corporation at any time after: (1) the
expiration of the initial employment term specified in paragraph 2, (2) he has
completed ten (10) year's of employment with the Corporation, and (3) he has
been a party to this Agreement for five (5) years from the date set forth above.
The Employee's disability as defined in paragraph 8 shall not prevent the
satisfaction of this condition. In such event, Employee shall be deemed to have
been (i) employed throughout the initial employment term and (ii) a party to
this Agreement for five (5) years, as of January 1, 1998. Upon the Employee's
Normal Retirement from active and daily employment with the Corporation, the
Corporation shall/pay to the Employee supplemental income in an amount
determined under paragraph 10 hereof for a period of ten (10) years. Such
supplemental income shall be payable in monthly installments on the first
business day of each calendar month and shall commence on the first business day
of the first calendar month after the month of the Employee's Normal Retirement
from active and daily employment with the Corporation.

             (b) If the Employee should die or become disabled after Normal
Retirement but before receiving all 120 monthly payments hereunder, the
Corporation shall continue to make monthly payments to the Employee, in the case
of disability, or to Employee's surviving designated beneficiary or
beneficiaries, as specified in Exhibit A attached hereto. Such payments shall be
in an amount equal to twice the monthly amount paid or payable


                                       7
<PAGE>

as supplemental income pursuant to paragraph 10 and shall continue until the
remaining monthly payments have been paid. If no beneficiaries have been
designated, or if the designated beneficiaries have predeceased the Employee, or
the beneficiaries cannot be found, such payments shall be made to the Employee's
estate for the remaining payment periods. If the Employee's designated
beneficiaries survive the Employee but thereafter die before all remaining
payments have been made, the Corporation shall continue to make the remaining
monthly payments to the estate of the designated beneficiary last to die. In any
event, the Corporation may at any time elect to substitute payment hereunder in
the form of a lump-sum amount having a present value actuarially equivalent to
the total remaining supplemental income payments or paid-up annuity having a
value which shall produce the remaining monthly payments under this Agreement.

         7.  Deferred Retirement Supplemental Income. If the Employee, with the
approval of the Board of Directors of the Corporation, continues in active and
daily employment with the Corporation after he becomes eligible for Normal
Retirement, the amount of supplemental income specified in paragraph 10 hereof
shall be increased by the amounts set forth on Exhibit B for each full year that
receipt of such supplemental income is deferred and shall be paid commencing on
the latter of the first business day of the first calendar month after the month
in which the Employee actually retired from active and daily employment by the


                                       8
<PAGE>

Corporation. Supplemental income under this paragraph 7 shall be paid in the
same manner as specified in paragraph 6 hereof during the Employee's lifetime
and after his death.

         8.  Effect of Disability. The Employee's employment with the
Corporation shall be terminated if the Employee is prevented from performing his
duties for a continuous period of three (3) months by reason of any illness,
incapacity or disability which may be medically determined in a manner to the
reasonable satisfaction of the Board of Directors of the Corporation. Any such
disability shall automatically defer any supplemental income payments under this
Agreement until the Employee's sixty-fifth (65th) birthday unless Employee and
the Corporation shall mutually agree otherwise.

         9.  Death Benefits Prior to Retirement. If the Employee should die
while employed by the Corporation but prior to becoming entitled to supplemental
income under paragraph 6 or 7 hereof, the Corporation shall pay a death benefit
equal to twice the amount of supplemental income specified in paragraph 10
hereof. Such death benefit shall be paid every year for ten (10) years, under
the same terms and conditions as specified in paragraph 6 hereof.
Notwithstanding any other provision of this Agreement, no benefits shall be
payable under this Agreement if the Employee's death results from suicide,
whether or not the Employee was sane or insane, within two (2) years after the
Employee became a party to this Agreement.

                                       9
<PAGE>

         10. Amount of Supplemental Income. The amount of supplemental income
payable under this Agreement as of the date hereof shall be Seventy-Five
Thousand Dollars ($75,000) per year. The amount of supplemental income payable
under this Agreement shall be increased at the end of each calendar year
commencing with the year 1987 and ending with the year preceding the last year
during which supplemental income payments are made under this Agreement by a
percentage of such amount equal to the lesser of (1) three percent (3%), or (2)
the increase in the CPI as published by the United States Government for such
year. Adjustments shall be made in the manner described in paragraph 5.

         11. Termination of Employment.

             (a) If, at any time (except in the event of a Change in Control as
described below) (1) the Employee wishes to terminate his employment with the
Corporation, or (2) the Corporation wishes to terminate the Employee's
employment with the Corporation because of a determination by the Board of
Directors of the Corporation that the Employee has failed to perform his duties
in a reasonably satisfactory manner, then such party may so terminate the
Employee's employment with the Corporation by giving the other party six (6)
months' prior written notice of such termination. In the case of the Employee's
failure to perform his employment duties in a manner reasonably satisfactory to
the Board of Directors of the Corporation, the date of termination of the
Employee's employment with the Corporation may be determined at the discretion
of the


                                       10
<PAGE>

Corporation. Upon the Employee's termination of employment for cause by the
Corporation under this paragraph 11, the Employee shall forfeit all rights to
receive the Consulting Retainer payments and supplemental income hereunder
unless, as to supplemental income only, at the time of such termination he has
satisfied the requirements of paragraph 6 hereof and has not forfeited his
rights hereunder pursuant to paragraphs 14 or 15 hereof.

             (b) The Employee's employment with the Corporation shall not be
deemed to have been terminated because of the Employee's absence from active and
daily employment by reason of a bona fide temporary illness or disability (not
exceeding a period of ninety [90] days), authorized vacation, temporary leave of
absence granted by the Corporation for reasons of professional advancement,
education, health or government service, or military leave for any period
required to be treated as a leave of absence by virtue of any valid law or
agreement.

             (c) Notwithstanding the foregoing, in the event of (i) a Change of
Control (as defined below) of the PBSJ Corporation or of Post, Buckley, Schuh &
Jernigan, Inc. ("PBSJ Inc.") and (ii) the termination of the Employee's
employment by the Corporation or any successor thereto for any reason other than
for Cause (as defined below), or the voluntary termination by the Employee of

                                       11
<PAGE>

his employment hereunder for Good Reason (as defined below) at any time at least
six months after the effective date of the Change in Control, all of the terms
and conditions of this Agreement shall remain in full force and effect, and
shall be binding upon the Corporation, except that the Employee shall be deemed
to have satisfied each of the conditions to eligibility for Normal Retirement
set forth in paragraph 6(a) immediately prior to the effectiveness of any such
Change in Control. In the event of a termination for Cause under this paragraph
11(c), the Corporation shall have no further obligation under this Agreement to
make any payments to, or bestow any benefits on, the Employee from and after the
date of said termination, other than payments or benefits accrued for him
(including deferred retirement benefits) prior to the date of said termination.

             For purposes of this paragraph 11(c), a "Change in Control" shall
be deemed to have taken place if:

                  (i) any person (as such term is used in Section 13[d] and
14[d] of the Securities Exchange Act of 1934, as amended, but excluding the
Corporation, any of its subsidiaries, The PBSJ Corporation Profit Sharing Trust
and the PBSJ Corporation Employee Stock Ownership Plan and Trust), should
acquire direct or indirect ownership of 80% or more of the voting power of the
then outstanding securities of the PBSJ Corporation or PBSJ Inc. by any means
whatsoever; or

                  (ii) the shareholders of the PBSJ Corporation or PBSJ Inc.
should approve any one of the following transactions:

                                       12
<PAGE>

                           (x) the sale, lease, exchange or other transfer (in
                  one transaction or a series of related transactions) of all,
                  or substantially all, the assets of the PBSJ Corporation or
                  PBSJ Inc.; or

                           (y) any consolidation or merger of the PBSJ
                  Corporation or PBSJ Inc. in which the PBSJ Corporation or PBSJ
                  Inc., as the case may be, is not the surviving corporation,
                  other than a merger of the PBSJ Corporation or PBSJ Inc. in
                  which the holders of the common stock of the PBSJ Corporation
                  or PBSJ Inc. immediately prior to the merger have the same
                  proportionate ownership of the surviving corporation
                  immediately after the merger.

             For purposes of this paragraph 11 (c), Cause shall mean (i) fraud
or misappropriation of corporate funds; or (ii) conviction of a felony involving
moral turpitude and such conviction is no longer subject to direct appeal.

             For purposes of this paragraph 11, "Good Reason" shall be deemed to
exist under any of the following circumstances:

                  (i) the Employee has been assigned any duties inconsistent
with his position, duties, responsibilities and status with the Corporation
immediately prior to the effective date of the Change in Control (the "Effective
Date"), or has been assigned reporting responsibilities, titles or offices of a
lesser scope than those in effect immediately prior to the Effective Date, or he
has been removed from, or not re-elected


                                       13
<PAGE>

to, any of such positions, except in connection with the termination of his
employment for Cause;

                  (ii) the Corporation has reduced the Employee's base salary as
in effect immediately prior to the Effective Date or has failed to give him
annual salary increases consistent with performance review ratings as compared
with other employees of the same or similar rank;

                  (iii) the Corporation has required the Employee to be based at
any office or location other than that at which the Employee is based at the
Effective Date, except for travel reasonably required in the performance of the
Employee's responsibilities;

                  (iv) the Corporation has failed to comply with any provision
of this Agreement.

         12. Prior Agreements. This Agreement supercedes and terminates in all
respects that certain employment agreement executed by and between the
Corporation and the Employee dated May 30, 1985, as amended.

         13. Working Facilities and Expenses. During the employment term
specified in paragraph 2 hereof, the Employee shall be furnished with an office,
stenographic and administrative help, and such other facilities, services and
assistance which shall be suitable to his position and adequate for the
performance of his duties. In addition, during the employment term or any period
of consulting or advisory service, the Corporation shall reimburse the Employee
for all reasonable


                                       14
<PAGE>

expenses incurred by him for entertainment, travel, promotion and similar items
in connection with the performance of his duties as undertaken, assigned or
required.

         14. Reasons for Forfeiture. The Corporation shall stop payments to the
Employee hereunder if the Employee is involved in fraud, or if the Corporation
determines that the Employee has been grossly negligent or has been engaged in
willful misconduct in the course of his 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 the Employee if the Corporation determines that it is entitled to such
recoupment.

         15. Competition and Confidentiality. If, following retirement pursuant
to paragraph 6 or 7, and through the period until all payments have been made
under this Agreement, the Employee competes with the Corporation, reveals to any
third party any trade secrets or financial or other confidential information
concerning the Corporation, does not perform required services pursuant to
paragraph 4 hereof, or is convicted of a felony, any supplemental income
thereafter payable hereunder shall be forfeited. As used in this Agreement,
"compete" shall mean entering into, performing or engaging, directly or
indirectly, in the rendering of engineering services or allied professional
services similar to those provided by the Corporation, including but not limited
to consulting, planning


                                       15
<PAGE>

and surveying, either as an individual for his own account, or as a partner or
joint venturer, or as an employee or agent for any person or as an officer,
director, or shareholder of any business entity or otherwise, within the State
of Florida, or any state in which the Corporation has an office or offices.

         Employee acknowledges that his services under this Agreement are of a
special, unique, unusual, extraordinary, and intellectual character, and that a
breach by Employee of this paragraph 15 could cause the Corporation irreparable
injury and damage and would therefore cause a breach of this Agreement.

         16. Insurance Benefits. As additional compensation to the Employee for
services performed, after the Employee's retirement from active and daily
employment with the Corporation, the Corporation shall continue to pay for and
provide to the Employee and his wife major medical and hospitalization insurance
benefits of equal coverage and substantially similar to those major medical and
hospitalization insurance benefits paid for and provided to senior executives of
the Corporation, provided, however, that such insurance shall not provide
coverage or benefits substantially less valuable or protective than those now in
effect for the Employee. said insurance benefits shall be paid for and provided
to the Employee and his wife for so long as either of them shall live.
Notwithstanding the fact that said period of coverage extends beyond the period
specified in paragraphs 4, 6 and 7 of this Agreement, the Corporation and the
Employee hereby agree that said lifetime insurance coverage is in


                                       16
<PAGE>

the nature of supplemental income to the Employee, without any further or
additional services from the Employee to the Corporation. The payment for and
furnishing to the Employee of said lifetime insurance benefits by the
Corporation is subject to and conditioned upon the Employee's compliance with
the terms and conditions of this Agreement.

         17. Assignment. Neither the Employee nor any designated beneficiary,
nor any other payee under this Agreement, shall have any power to transfer,
assign, anticipate, hypothecate or otherwise encumber in advance any of the
supplemental income payable hereunder, nor shall any supplemental income payable
be subject to seizure for the payment of any debts or judgments of the Employee
or any payee or be transferable by the Employee or any payee by operation of law
in the event of such person's bankruptcy, insolvency or otherwise.

         18. Participation in Other Employee Benefit Plans. Any retirement or
disability compensation payable under this Agreement shall not be deemed salary
or other compensation to the Employee for the purpose of computing benefits to
which he may be entitled under any pension plan or other arrangement of the
Corporation for the benefit of its employees. Nothing contained herein shall in
any manner modify, impair or affect the existing or future right or interest of
the Employee to receive any employee benefits to which he would otherwise be
entitled, or as a participant in any future incentive profit-sharing or bonus
plan, stock option plan or pension plan of the Corporation,


                                       17
<PAGE>

applicable generally to salaried employees. The rights and interests of the
Employee to any employee benefits or as a participant or beneficiary in or under
any or all such plans shall continue in full force and effect unimpaired, and
the Employee shall have the right at any time hereafter to become a participant
or beneficiary under or pursuant to any and all such plans.

         19. Arbitration. Any controversy or claim arising out of or relating to
this Agreement, or the breach thereof, shall be settled by arbitration conducted
by and in accordance with the rules then in existence of the American
Arbitration Association. Judgment upon the award rendered by the arbitrators may
be entered in any court having jurisdiction thereof.

         20. Life Insurance and Funding.

             (a) The Corporation, in its sole discretion, may apply for and
procure as owner and for its own benefit insurance on the life of the Employee
in such amounts and in such forms as the Corporation may choose. The Employee
shall have no interest whatsoever in any such policy or policies, but, at the
request of the Corporation, shall submit to medical examinations and supply such
information and execute such documents as may be required by the insurance
company or companies to which the Corporation has applied for insurance.

             (b) The supplemental income provided herein shall constitute an
unfunded promise of the Corporation, and the benefits and rights of the Employee
or his beneficiary or estate


                                       18
<PAGE>

to supplemental income under this Agreement shall be solely those of an
unsecured creditor of the Corporation. Any insurance policy or other assets
acquired or held by the Corporation in connection with the liabilities assumed
by it pursuant to this Agreement shall not be deemed to be held under any trust
for the benefit of the Employee of his estate or a beneficiary thereof or to be
security for the performance of the obligations of the Corporation but shall be
and remain a general, unpledged and unrestricted asset of the Corporation.

         21. Professional Liability Coverage. The Corporation shall provide
coverage to and for the Employee, as a named insured, under any
Architects/Engineers Professional Liability Insurance policy maintained by the
Corporation. Said coverage provided to the Employee shall be coextensive with

litigation and arbitration expenses and attorneys' fees at both trial and
appellate levels.

directed, or, whether or not the same is actually received, if sent by
registered or certified mail, postage and charges prepaid, properly addressed to
the addressee's last known address.

         24. Claims Procedure. In the event Employee (or Beneficiary) does not
receive a distribution of benefits to which he or she believes he or she is
entitled, he or she may present a claim to the Board of Directors of the
Corporation. The claim for benefits must be in writing and addressed to the

                  This Second Amendment to the Consulting/Supplemental

is dated as of the 10th day of October, 1989.

                  WHEREAS, the Employee has consented, as evidenced hereby, to a
change of residence in order to better serve the Corporation; and

                  WHEREAS, the Employee has assumed additional responsibilities
for the Corporation; and

                  WHEREAS, the parties hereto desire to amend the Agreement, as
amended, to modify the physical location from which Employee's services shall be
performed and to reflect the assumption of additional responsibilities; and

                  WHEREAS, the parties hereto desire to further amend the
Agreement to more accurately reflect the understanding of the parties with
respect to the manner of payment of certain benefits payable to Employee under
the Agreement;

                  NOW, THEREFORE, in consideration of the mutual promises,
covenants and agreements contained in this Second Amendment and the Agreement,
as amended, and intending to be legally bound, the parties hereto agree as
follows:

         1. Employment. The final sentence of paragraph l(b) of the Agreement,
as amended, is hereby deleted in its entirety and the following substituted
therefor:

            "The Employee will not be required to perform any services hereunder
            which will necessitate moving his residence from Miami, Florida,
            unless he agrees, in writing, to such relocation."

         2. Consulting. The reference to "ten (10) years" in the third sentence
of paragraph 4 of the Agreement, as mended, is hereby deleted, and the phrase
"seven (7) years" is hereby substituted therefor.

         3. Consulting Compensation. The reference to "Twenty Thousand Dollars

substituted therefor:

         6. Retirement Supplemental Income.

            (a)  The Employee is eligible for Normal Retirement from active and
                 daily employment with the Corporation at any time after: (1)
                 the expiration of the initial employment term specified in
                 paragraph 2 which ends on January 1, 1998, (2) he has completed
                 ten (10) years of employment with the Corporation, and (3) he
                 has, been a party to this Agreement for five (5) years from the
                 date set forth above. The Employee's disability as defined in
                 paragraph 8 shall not prevent the satisfaction of this
                 condition. In such event, Employee shall be deemed to have
                 satisfied the foregoing condition as of January 1, 1998.

            (b)  Commencing January 1, 2005, provided the Employee shall have
                 satisfied the eligibility requirements for Normal Retirement,
                 the Corporation shall pay to the Employee Supplemental Income
                 in an amount determined under paragraph 10 hereof for a period
                 of eight (8) years. If the Employee, with the approval of the
                 Board of Directors of the Corporation, continues in active and
                 daily employment with the Corporation after January 1, [1998],
                 the amount of Supplemental Income specified in paragraph 10
                 hereof all be increased by the amounts set forth in Exhibit B
                 for each full year after such date. Such Supplemental Income
                 shall be payable in monthly installments on the first business
                 day of each calendar month.

         7. Continuation of Payment in Event of Death or Disability.

                 If the Employee should die or become disabled, and in either
                 case not have received 180 monthly payments hereunder, the
                 Corporation shall make, or shall continue to make such monthly
                 payments to the Employee in the case of disability, or to
                 Employee's surviving designated beneficiary or beneficiaries,
                 as specified in Exhibit A attached hereto, subject, however, in
                 the case of


                                     - 2 -
<PAGE>

                 disability to paragraph 8 hereof. Such payments shall be in an
                 amount equal to the monthly amount paid or payable as
                 supplemental income pursuant to paragraph 10 (computed as of
                 the date of death or disability and only adjusted for CPI or
                 otherwise after such date) and shall continue until the
                 remaining monthly payments have been paid. If no beneficiaries
                 have been designated, or if the designated beneficiaries have
                 pre-deceased the Employee, or if the beneficiaries cannot be
                 found, such payments shall be made to the Employee's estate for
                 the remaining payment periods. If the Employee's designated
                 beneficiaries survive the Employee but thereafter due before
                 all remaining payments have been made, the Corporation shall
                 continue to make the remaining monthly payments to the estate
                 of the designated beneficiary last to die. In any event, the
                 Corporation may at any time elect to substitute payment
                 hereunder in the form of a lump-sum amount having a present
                 value actuarially equivalent to the total remaining
                 supplemental income payments or a paid-up annuity having a
                 value which shall produce the remaining monthly payments under
                 this Agreement.

         9.       Maximum Payment.

                  In no event shall the aggregate number of payments for both
                  Consulting and Supplemental Income combined exceed 180
                  payments nor shall such payments be for a period greater than
                  fifteen (15) years. Subject to satisfaction of applicable
                  eligibility requirements or conditions, consulting
                  compensation and supplemental income payments may run
                  concurrently unless the Corporation and the Employee shall
                  otherwise agree.

         5. Amount of Supplemental Income. The reference to "Twenty Thousand
Dollars ($20,000.00)" in the first sentence of paragraph 10 of the Agreement, as
amended, is hereby deleted, and "Sixty-Five Thousand Dollars ($65,000.00)" is
hereby substituted in lieu thereof.

         6. Competition and Confidentiality. The phrase "pursuant to paragraph 6
or 7' in the first sentence of paragraph 15 of the Agreement, as amended, is
hereby deleted in its entirety and the phrase "from active and daily employment"
substituted therefor.

provision thereof.

                               Fifth Amendment to

           Consulting/Supplemental Retirement/Death Benefits Agreement

         This Fifth Amendment to the Consulting/Supplemental Retirement/Death
Benefits Agreement (hereinafter referred to as the "Agreement"), dated as of
November 6, 1987, as amended, by and between Post, Buckley, Schuh & Jernigan,
Inc., The PBSJ Corporation, Florida corporations with principal offices in
Miami, Florida (together hereinafter referred to as the "Corporation"), and H.
Michael Dye (hereinafter referred to as the "Employee"), is dated as of the 19th
day of May, 1998.

         WHEREAS, the parties hereto desire to further amend the Agreement to
reflect the current and revised understanding of the parties with respect to
certain rights, obligations and benefits of the parties under the Agreement;

         NOW, THEREFORE, in consideration of the mutual promises, covenants and
agreements contained in this Fifth Amendment and the Agreement, as amended, and
intending to be legally bound, the parties hereto agree as follows:

         1. Consulting Compensation. In addition to the consulting compensation
amounts included in the original Consulting/Supplemental Retirement/Death
Benefits Agreement dated November 6, 1987 and all amendments preceding this
amendment, the Corporation agrees to pay an additional consulting retainer of
twenty-five thousand dollars ($25,000) per year to the employee for the five (5)
year consulting period of time specified in the original agreement and
amendments. The amount of the consulting retainer payable under this amendment
shall be increased at the end of each calendar year commencing with the year
1998 and ending with the year preceding the last year during which consulting
payments are made under this amendment by a percentage of such amount equal to
the lesser of (1) three percent (3%), or (2) the increase in the national
Consumer Price Index ("CPI") as published by the United States Government for
such year. Adjustments shall be effective on January 1 based on the CPI for the
prior year computed from December to December. For the purposes of this
amendment, the CPI referred to shall be all items shown on the U.S. city average
for urban wage earners and clerical workers (including single workers), all
items, groups, subgroups and special groups of items as promulgated by the
Bureau of Labor Statistics of the U.S. Department of Labor. If the U.S.
Department of Labor ceases to publish the above described CPI, then such CPI as
may be published by such Department most nearly approaching said discontinued
CPI shall be used in making the above adjustments. If the Department
discontinues any such CPI, then such CPI as may be published by another U.S.
Government agency, as most nearly approximates the CPI first above referred to,
shall govern, subject to the application of an appropriate conversion factor to
be furnished by the governmental agency publishing the adopted CPI.

         2. Miscellaneous.

            (a) Except as expressly provided herein, the Agreement, as amended,
shall remain in full force and effect without any modification or waiver of any
provision thereof.

            (b) This Fifth Amendment shall be governed by the laws of the State
of Florida, without regard to the principles of conflicts of laws thereunder.

            (c) The Agreement, as amended, sets forth the entire understanding
of the parties as to the subjects discussed therein, and supersedes all prior
understandings, commitments, agreements, whether oral or written, relating to
the subject matter thereof.

            (d) This Fifth Amendment may be executed in any number of
counterparts, and each such counterpart shall for all purposes be deemed an
original.
