Exhibit 10-f

                                    AGREEMENT

     This  AGREEMENT  is  dated  as of May  13,  1997 by and  between  Trustmark
Corporation,  a Mississippi corporation (the "Company"), and Richard G. Hickson,
(the "Executive").
     The Company  desires to employ the Executive  and the Executive  desires to
accept such employment on the terms and conditions of this Agreement.
     NOW,  THEREFORE,  in  consideration  of the mutual  premises and agreements
herein  contained,  and other good and valuable  consideration,  the receipt and
adequacy of which is hereby acknowledged,  the parties,  intending to be legally
bound, hereby agree as follows:
     1.  Term of  Employment.  Subject  to  Section  5  hereof,  the term of the
Executive's  employment  under this Agreement  shall commence on the 13th day of
May, 1997 (the  "Commencement  Date"),  and shall continue  until  terminated as
provided in Section 5 (the "Term").
     2. Duties of Employment. The Executive hereby agrees for the Term to render
his services to the Company as its  President  and Chief  Executive  Officer and
such other office or position with the Company as may be reasonably requested by
the  Board  of  Directors  of the  Company  (the  "Board"),  and  in  connection
therewith,  to  perform  such  duties  commensurate  with his office as he shall
reasonably be directed by the Board to perform. The Executive shall perform such
duties faithfully and diligently at all times. The Executive shall have no other
employment  while he is employed by the  Company;  provided,  however,  that the
Executive may serve on the boards of directors of companies which do not compete
with the Company and in such capacity attend regularly  scheduled board meetings
to the extent approved in writing in advance by the Board. When and if requested
to do so by the Board,  the  Executive  shall serve as a director and officer of
any  subsidiary  or  affiliate  of the  Company.  The Company  shall  notify the
Executive if it believes that the Executive has breached any of his  obligations
under this Section 2; in such event,  the Executive  shall have thirty (30) days
within  which to cure such  breach,  other  than a breach of his  obligation  to
refrain from  employment with any person or entity other than the Company or any
of its subsidiaries or affiliates.
     3.  Compensation  and  Other  Benefits.  
     3.1. Salary.  As his full base compensation for all services to be rendered
by the Executive  during the Term, the Company shall pay to the Executive a base
salary at an annual rate of $400,000 for the 1997  calendar year of the Term and
for each successive year of the Term in an amount  established  each year by the
Compensation  Committee  of the Board and the  Board,  but in no event less than
$400,000 annually.  Payment shall be made in accordance with the Company's usual
payroll  practices  for senior  executives.  The annual base salary set forth in
this  Section  3, as in effect at any  particular  time,  shall  hereinafter  be
referred  to as the "Base  Salary."  The Company  shall  withhold or cause to be
withheld  from the Base Salary (and other wages  hereunder)  all taxes and other
amounts as are required by law to be withheld.
     3.2. Annual Bonus. In addition to the Base Salary, the Executive shall have
the  opportunity  annually  to earn as a bonus fifty  percent  (50%) of his Base
Salary (the "Target Award Opportunity"). In establishing the actual bonus earned
each year by the Executive (the "Annual Bonus"),  the Compensation  Committee of
the Board,  in  consultation  with the  Executive,  shall have the discretion to
increase  the Annual  Bonus above or decrease  the Annual Bonus below the Target
Award  Opportunity  for that  year.  In so doing  the  Compensation  Committee's
determination  shall be based upon an assessment of the  performance of both the
Executive and the Company taking into






consideration  such performance  goals as may be established by the Compensation
Committee  periodically  in  consultation  with the Executive.  The  Executive's
Annual Bonus shall not exceed seventy-five  percent (75%) of the Base Salary for
any one year.  Notwithstanding  the foregoing,  the Executive's Annual Bonus for
the 1997  calendar  year of the Term  shall be an  amount  not less  than  fifty
percent  (50%)  of the  Base  Salary  prorated  for the  Executive's  period  of
employment for the 1997 calendar year.
     3.3.  Stock  Options.  The Company will grant to the  Executive for no cash
consideration  an option to acquire 28,000 shares of common stock of the Company
at a  price  equal  to  the  fair  market  value  of  the  common  stock  on the
Commencement  Date in  accordance  with the Company's  1997 Long Term  Incentive
Plan. These options however shall vest as follows:  25% on the first anniversary
of the  Commencement  Date,  and 25% on each such  successive  anniversary  date
thereafter  until fully vested,  unless  earlier vested as provided in Section 5
herein.  Subsequent  stock  option  grants  may be made in such  amounts  as are
determined in the sole discretion of the Compensation Committee of the Board.
     3.4.  Vacation.  The  Executive  shall be  entitled  to four  weeks of paid
vacation for the 1997 calendar year of the Term and for each successive calendar
year of the Term  thereafter.  Upon  termination of the Term of this  Agreement,
Executive  shall be paid on a pro rata  basis for all  unused  vacation  granted
during  the year of  termination  at the Base  Salary  rate then  existing.  The
Executive  shall not be paid for any unused vacation if terminated for Cause (as
hereinafter  defined).  No payment  shall be made for unused  vacation  from any
prior years.
     3.5.  Participation  in Employee  Benefit  Plans.  The  Executive  shall be
permitted  to  participate  in all group life,  hospitalization  and  disability
insurance plans, health programs,  pension plans, similar benefit plans or other
so-called "fringe benefit programs" of the Company (the "Employee  Benefits") as
are now existing or as may hereafter be revised or adopted and offered to senior
executives  generally  to  the  extent  the  Executive  is  eligible  under  the
eligibility provisions of the relevant plan.
     4. Confidentiality.
     4.1.  The  Executive   covenants   and  agrees  that  all  trade   secrets,
confidential  information (including but not limited to confidential information
with respect to marketing,  product offerings or expansion plans), and financial
matters  of  the  Company  and  its  subsidiaries  (collectively   "Confidential
Information")  which are learned by him in the course of his  employment  by the
Company shall be held in a fiduciary capacity and treated as confidential by him
and shall not be disclosed,  communicated  or divulged by him or used by him for
the benefit of any person or entity (other than the Company, its subsidiaries or
affiliates)  unless expressly  authorized in writing by the Board, or unless the
Confidential  Information  becomes  generally  available to the public otherwise
than through disclosure by the Executive.
     4.2.  The  Executive  agrees  that (1)  during  the  period he is  employed
hereunder  and for a period  of  twelve  (12)  months  thereafter,  he will not,
without the prior written consent of the Board,  directly or indirectly solicit,
entice,  persuade,  or  induce  any  employee,   director,  officer,  associate,
consultant, agent or independent contractor of the Company (i) to terminate such
person's  employment or engagement by the Company or (ii) to become  employed by
any person, firm partnership,  corporation,  or other such enterprise other than
the Company, its subsidiaries or affiliates,  and (2) he shall not following the
termination  of  his  employment  hereunder  represent  that  he is in  any  way
connected  with the business of the Company  (except to the extent  agreed to in
writing by the Company).






     4.3. The Executive  agrees that during the period he is employed  hereunder
and, in the event the Company terminates his employment  hereunder for Cause (as
hereinafter  defined)  or the  Executive  terminates  his  employment  hereunder
without Good Reason (as hereinafter defined), for a period of twelve (12) months
thereafter  he will not (except as a  representative  of the company or with the
prior written  consent of the Board)  engage,  participate or make any financial
investment, as an employee,  director,  officer, associate,  consultant,  agent,
independent contractor, lender or investor, in the business of any person, firm,
partnership,   corporation  or  other  enterprise  that  is  engaged  in  direct
competition  with the  business  of the  Company  in the  State of  Mississippi.
Nothing in this Section 4.3 shall be construed  to preclude the  Executive  from
making any investments in the securities of any business  enterprise  whether or
not engaged in competition with the Company,  to the extent that such securities
are actively traded on a national securities exchange or in the over-the-counter
market in the United States or on any foreign securities  exchange and represent
less  than  one-  percent  (1%) of any  class  of  securities  of such  business
enterprise.
     5. Termination and Severance.
     5.1.  Notice of  Termination.  Subject to the provisions of this Agreement,
the Company and the Executive may terminate the Term on thirty (30) days written
notice to the other party,  which  notice shall  specify in detail the cause for
termination, except that no prior written notice need be given by the Company in
the event it  terminates  the  Executive's  employment  hereunder  for Cause (as
hereinafter defined and subject to applicable cure provisions).
     5.2.  Resignation.  Except as  otherwise  provided  in  Section  5.6 or 5.7
herein,  the  Executive  may  voluntarily  terminate  the Term and  resign  from
employment  with the  Company  by  written  notice  to  Company  specifying  the
effective  date of such  resignation.  Upon receipt of such notice,  the Company
shall have the right to terminate the Term  immediately  or at such earlier date
as the Company may elect by written notice to the Executive.  Therefore, Company
shall  have no further  obligations  or  liabilities  to  Executive,  except for
obligations to pay the Executive (1) any unpaid Base Salary and accrued vacation
benefits  earned  through the date of  termination;  and,  (2) the Annual  Bonus
earned  for  the  calendar  year  immediately  preceding  the  calendar  year of
termination to the extent not already paid.
     5.3. Death. In the event of the Executive's death during the Term, the Term
and the Executive's employment shall terminate automatically,  and Company shall
pay to his spouse or designated  beneficiary,  or if none, to his estate (1) any
unpaid Base  Salary and accrued  vacation  benefits  earned  through the date of
death, (2) the Annual Bonus earned for the calendar year  immediately  preceding
the calendar  year of death to the extent not already  paid,  and (3) a pro rata
share of the Target Award Opportunity for the calendar year of death (calculated
on the basis of the  number of days  elapsed  in such year  through  the date of
death).  The  Company  shall  pay  to  the  Executive,  his  spouse,  designated
beneficiary  or estate,  as the case may be, any amounts owing  pursuant to this
Section 5.3 in a single lump sum within fifteen (15) days following  termination
of the Executive's employment.
     5.4.  Disability.  If the Executive becomes physically or mentally disabled
during the Term so that he is unable to perform  the  services  required  of him
pursuant to this  Agreement  for a period of 90 days,  the Company may terminate
the Term and the Executive's services hereunder effective the 91st day after the
date of such  disability,  at which time the Company  shall  promptly pay to the
Executive the payments set forth in Section 5.3 hereof.



     5.5. For Cause. The Company may terminate the Executive's employment during
the Term for Cause. For purposes of this Agreement,  "Cause" shall mean that the
Executive  has (i)  committed  an act of personal  dishonesty,  embezzlement  or
fraud;  (ii) has misused  alcohol or drugs;  (iii) failed to pay any  obligation
owed  to the  Company  or any  affiliate;  (iv)  breached  a  fiduciary  duty or
deliberately  disregarded  any rule of the  Company  or any  affiliate;  (v) has
committed an act of willful  misconduct,  or the intentional  failure to perform
stated duties;  (vi) has willfully  violated any law, rule or regulation  (other
than  misdemeanors,  traffic  violations  or  similar  offenses)  or  any  final
cease-and-desist   order;   (vii)  has  disclosed   without   authorization  any
Confidential  Information of the Company or any affiliate, or has engaged in any
conduct  constituting  unfair  competition,  or has induced any  customer of the
Company or any Affiliate to breach a contract with the Company or any affiliate.
     If at any time during the Term the Company  shall  terminate  the Executive
for  "Cause"  the  Company  shall pay the  Executive  (i) any unpaid Base Salary
earned through the date of termination, and (ii) the Annual Bonus earned for the
calendar year  immediately  preceding the calendar  year of  termination  to the
extent not already paid, without any further obligations to the Executive.
     5.6.  Change  in  Control.  If at any time  during  the  Term  the  Company
experiences  a Change in Control  and within  three (3) years after the date the
Change in Control  occurs (i) the Term and the  Executive are  terminated  other
than for Cause,  death or  disability  or (ii) the  Executive  resigns  for Good
Reason, the following provisions shall apply:
     (i) "Change in Control" shall mean any one of the following events: (1) the
     acquisition  by any person of ownership  of,  holding or power to vote more
     than 20% of the Company's  voting stock,  (2) the acquisition by any person
     of the  ability to control  the  election  of a majority  of the  Company's
     Board,  (3) the acquisition of a controlling  influence over the management
     or policies of the Company by any person or by persons  acting as a "group"
     (within the meaning of Section 13(d) of the Securities Exchange Act of 1934
     (Exchange  Act),  or  (4)  during  any  period  of two  consecutive  years,
     individuals  (the  "Continuing  Directors")  who at the  beginning  of such
     period  constitute the Board (the "Existing Board") cease for any reason to
     constitute at least two-thirds thereof,  provided that any individual whose
     election or nomination  for election as a member of the Existing  Board was
     approved by a vote of at least two-thirds of the Continuing  Directors then
     in office shall be considered a Continuing  Director.  Notwithstanding  the
     foregoing, in the case of (1), (2) and (3) hereof,  ownership or control of
     the  Company's  voting stock by the only  subsidiary  of the Company or any
     employee  benefit plan sponsored by the Company or any subsidiary shall not
     constitute a Change in Control. For purposes of this subparagraph, the term
     "person"  refers to an individual  or a  corporation,  partnership,  trust,
     association,   joint  venture,   pool,   syndicate,   sole  proprietorship,
     unincorporated  organization  of any other form of entity not  specifically
     listed herein;
     (ii) "Good  Reason"  shall mean (1) a demotion in the  Executive's  status,
     title  or  position,  or the  assignment  to the  Executive  of  duties  or
     responsibilities which are materially  inconsistent with such status, title
     or  position;  (2) a  material  breach of this  Agreement  by the  Company,
     provided the Company has not remedied  such breach  within thirty (30) days
     of  receipt of  written  notice of such  breach;  (3) a  relocation  of the
     executive  offices of the Company to a location  more than 50 miles outside
     of Jackson,  Mississippi  without the Executive's  written consent given to
     the  Company  within  thirty  (30)  days  of  the  Executive's  receipt  of
     notification  of such  relocation  by the Company or (4) the failure of the
     Executive to be named as the Chief  Executive  Officer of any  successor by
     merger to the Company.  Any good faith  determination of "Good Reason" made
     by the Executive shall be conclusive; and



     (iii) The Company  shall pay to the  Executive in a lump sum in cash within
     thirty (30) days after the effective  date of  termination  (except for the
     payment  described in Section 5.6 (iii)(D)  which shall be paid on the date
     specified  therein) the aggregate of the following  amounts:  A. The sum of
     (1) the Executive's Base Salary and accrued vacation benefits
through the date of termination to the extent not  theretofore  paid and (2) the
product of (x) the sum of (i) Executive's Base Salary rate immediately  prior to
the Change in Control and (ii) the highest Annual Bonus amount earned in any one
of the three (3) years  preceding  the year of the Change in Control,  and (y) a
severance multiple of 4.5 if the termination occurs during the first twelve (12)
months after the Commencement  Date, of 3.5 if the termination occurs during the
second  twelve  months  after the  Commencement  Date or 3.0 if the  termination
occurs during any successive twelve month period during the Term thereafter. For
the purposes of the  calculation in this Section  5.6(iii)(A),  the  Executive's
Annual Bonus for 1997 shall be annualized; e.g., if the Executive's Annual Bonus
for 1997 is  $125,000,  then his  Annual  Bonus  for this  calculation  shall be
$200,000  ($125,000 / 5 months x 12).  Also,  if the Executive has been employed
fewer than three (3) years when the Change in Control  occurs,  then the highest
Annual Bonus actually earned in the previous year or years shall apply;
     B. The Company  shall  continue to provide to the  Executive  the  Employee
Benefits for such period of time  following the effective date of termination as
is equal in years to the  severance  multiple  set forth in Section 5.6 (iii)(A)
above, reduced by any employment benefits received from later employment;
     C. Any stock options  granted  pursuant to this  Agreement or the Company's
1997 Long Term  Incentive Plan which have not vested shall  immediately  vest in
the Executive in full. Any such stock options which were intended by the parties
to be incentive stock options but which exceed the "$100,000  first  exercisable
rule" shall be converted into non-qualified stock options; and
     D. If the  Executive is unable to sell his home in Jackson for at least the
lesser of  $800,000  or the then  current  appraised  value of the home within 4
months  following the effective date of his  termination,  Company shall acquire
such property at this time for a purchase  price equal to the lesser of $800,000
or the then  current  appraised  value of the  Executive's  home in  Jackson  in
exchange for an unencumbered deed to the property.
     5.7. No Change in Control. If there has not been a Change in Control within
three (3) years of the date of termination  and the Company  terminates the Term
and the Executive's employment for a reason other than Cause, death,  disability
or the Executive's normal retirement or if the Executive gives written notice of
voluntary termination for any reason during the period February 13, 1998 through
May 12,  1998,  the Company  shall pay to the  Executive  the  aggregate  of the
following  amounts in a lump sum in cash  (except for the payment  described  in
Section 5.7(D) which shall be paid on the date specified therein).
     A. The sum of (1) the Executive's Base Salary and accrued vacation benefits
through the date of termination to the extent not theretofore paid;
     B.  The  amount  equal  to the  product  of (1)  1.5 and (2) the sum of (x)
Executive's  annual Base Salary and (y) the Executive's Target Award Opportunity
in effect for the calendar year in which the termination occurs;
     C. The Company  shall  continue to provide to the  Executive  the  Employee
Benefits for a period of eighteen  months  following the  effective  date of the
termination, reduced by any employee benefits received from later employment;



     D. If the  Executive is unable to sell his home in Jackson for at least the
lesser of  $800,000  or the then  current  appraised  value of the home within 4
months  following the effective date of his  termination,  Company shall acquire
such property at this time for a purchase  price equal to the lesser of $800,000
or the then  current  appraised  value of the  Executive's  home in  Jackson  in
exchange for an unencumbered deed to the property;
     E. Except for the amount, if any, described in paragraph D above and except
as provided in paragraph F below,  the payments  hereunder  shall be made within
thirty (30) days after the effective date of termination; and
     F.  Notwithstanding  the foregoing,  if the Executive  voluntarily  resigns
during the period  February 13, 1998 through May 12, 1998, the Company shall not
be obligated to make the payments set forth in this Section 5.7,  including  any
amount  under  Paragraph  D,  until  the end of six  (6)  months  following  the
effective  date of such  termination  and  then  only if the  Executive  has not
accepted  employment  in a comparable or better  position  with another  person,
company or institution during such six (6) month period.
     5.8 Retirement.  Unless terminated  earlier pursuant to this Section 5, the
Term and the Executive's  employment shall  automatically  terminate on the last
business  day of the  calendar  year in which the  Executive  reaches age 65, in
which event, the Executive shall be entitled to receive such retirement benefits
which have accrued to the Executive by virtue of his employment  hereunder,  but
not the severance benefits described in Sections 5.6 and 5.7 hereof.
     5.9. Return of Documents on Termination.  On termination of employment, the
Executive shall promptly return to the Company all documents, materials, papers,
data,  computer discs,  statements and any other written material (including but
not limited to all copies thereof) and other property of the Company.
     6. Expenses.  
     6.1. General.  The Company shall reimburse the Executive for his reasonable
out-of-pocket  expenses  incurred  pursuant to this  Agreement and in connection
with the performance of his duties under this Agreement,  in accordance with the
general policy of the Company,  upon  submission of  satisfactory  documentation
evidencing such expenditures.
     7. Moving Expenses and Signing Bonus.
     7.1.  In addition to the  reimbursement  of expenses  pursuant to Section 6
hereof , the Company  shall  reimburse  the  Executive  for Moving  Expenses (as
defined below) upon  presentation to the Company of an itemized expense voucher.
As used in this  Section  7, the term  "Moving  Expenses"  means any  reasonable
out-of-pocket  expenses  incurred  by  the  Executive  in  connection  with  the
relocation  of his  residence  from  Atlanta,  Georgia to Jackson,  Mississippi,
including,  but not limited to (1) the  reasonable  cost of travel to Jackson by
Executive and his wife to locate a residence, including economy class round trip
airfare,  lodging,  car rentals and meals;  (2)  economy  class  airfare for the
Executive and his family from Atlanta to Jackson on the date of relocation ("the
Moving  Date") (3)  temporary  lodging  expenses  in Jackson for a period not to
exceed eight (8) months  while the  Executive is locating or building and moving
into such residence (4) the physical transfer of the Executive's possessions and
automobiles,   and  (5)  any  other  reasonable   expenses  incidental  to  such
relocation.
     7.2. Within a reasonable  period of time after the  Commencement  Date, the
Company  shall pay the Executive  the sum of Two Hundred  Thirteen  Thousand One
hundred Dollars ($213,100.00),  which amount is intended by the parties to cover
all incidental  direct expenses  associated with moving into the Executive's new
residence in Jackson, certain carrying costs






associated with the Executive's residence in Atlanta, the sale of such residence
and forfeited benefits at the Executive's current place of employment.
     8.  Non-Assignment.  This Agreement and all of the  Executive's  rights and
obligations hereunder are personal to the Executive and shall not be assignable;
provided,  however,  that upon his death all of the  Executive's  rights to cash
payments under this Agreement shall inure to the benefit of his widow,  personal
representative,  designees or other legal  representatives,  as the case may be.
Any person,  firm or  corporation  succeeding  to the business of the Company by
merger,  purchase,  consolidation  or  otherwise  shall  assume by  contract  or
operation of law the obligations of the Company  hereunder,  provided,  however,
that the Company  shall,  notwithstanding  such  assumption,  remain  liable and
responsible for the fulfillment of its obligations under this Agreement.
     9.  Arbitration.  In the event of a dispute  between  the  Company  and the
Executive over the terms of this Agreement  which is not settled by the parties,
the company and the Executive  agree to settle any and all such disputed  issues
by  arbitration  in  accordance  with the  then-existing  rules of the  American
Arbitration Association. The Company and the Executive shall jointly appoint one
person to act as the  arbitrator.  In the event the  Company  and the  Executive
cannot agree to an arbitrator  within 30 days, the arbitrator shall be chosen by
the American  Arbitration  Association.  The decision of the arbitrator shall be
binding upon the parties and there shall be no appeal  therefrom  other than for
bias, fraud or misconduct. The costs of the arbitration,  including the fees and
expenses of the arbitrator,  shall be borne fifty percent by the Company, on the
one hand, and fifty percent by the Executive, on the other, but each party shall
pay its own attorneys' fees and other professional costs and expenses; provided,
however, that if the arbitrator shall rule for the Executive,  the Company shall
pay  or  reimburse  the  Executive's   reasonable   attorneys'  fees  and  other
professional  costs and expenses and the  Executive's  share of the  arbitration
costs  incurred  in  connection  with  such  arbitration.   Notwithstanding  the
foregoing, it is specifically understood that the Executive shall remain free to
assert and enforce in any court of competent  jurisdiction  such rights, if any,
as the  Executive  may have under  federal law,  including  without  limitation,
rights arising under Title VII of the Civil Rights Act of 1964, as amended,  the
Age Discrimination and Employment Act of 1967, as amended,  and/or the Americans
With Disabilities Act of 1990. Any decision  rendered by the arbitrator,  except
as provided above, shall be final and binding.
     10. Excise Tax Limitation.
     10.1. Notwithstanding anything contained in this Agreement (or in any other
agreement between the Executive and the Company) to the contrary,  to the extent
that any  payments  and benefits  provided  under this  Agreement or payments or
benefits  provided to, or for the benefit of, the Executive  under the Trustmark
Corporation  1997 Long Term Incentive Plan or any other plan or agreement  (such
payments or benefits are  collectively  referred to as the "Payments")  would be
subject to the excise tax (the "Excise  Tax")  imposed under Section 4999 of the
Internal  Revenue Code of 1986, as amended  (the"Code"),  the Payments  shall be
reduced if and to the extent that a reduction  in the  Payments  would result in
the  Executive  retaining a larger  amount,  on an after-tax  basis (taking into
account federal, state and local income taxes and the Excise Tax), than he would
have retained had he been entitled to receive all of the Payments  (such reduced
amount is hereinafter  referred to as the "Limited Payment Amount").  Unless the
Executive  shall have given prior  written  notice to the Company  specifying  a
different  order to  effectuate  the  reduction,  the Company  shall  reduce the
Payments by first reducing or  eliminating  those payments or benefits which are
not payable in cash and then by reducing or eliminating  cash payments,  in each
case in reverse order  beginning  with payments or benefits which are to be paid
the farthest in time from the date the "Determination"



(as  hereinafter  defined) is  delivered to the Company and the  Executive.  Any
notice given by the  Executive  pursuant to the  preceding  sentence  shall take
precedence  over the  provisions  of any other plan,  arrangement  or  agreement
governing  the   Executive's   rights  and   entitlements  to  any  benefits  or
compensation.
     10.2. The  determination as to whether the Payments shall be reduced to the
Limited  Payment  Amount  and the amount of such  Limited  Payment  Amount  (the
"Determination")  shall be made at the Company's  expense by an accounting  firm
selected by the Company and  reasonably  acceptable  to the  Executive  which is
designated as one of the five (5) largest  accounting firms in the United States
(the "Accounting  Firm"). The Accounting Firm shall provide the Determination in
writing,  together with detailed supporting  calculations and documentation,  to
the  Company and the  Executive  on or prior to the date of  termination  of the
Executive's employment if applicable,  or at such other time as requested by the
Company  or by the  Executive.  Within  ten  (10)  days of the  delivery  of the
Determination  to the Executive,  the Executive  shall have the right to dispute
