Company or any of its  subsidiaries  or affiliates  which he may then possess or
have under his control.

        3.     COMPENSATION AND RELATED MATTERS.

               (a) BASE SALARY.  Executive  shall  receive a base salary paid by
the Company  ("Base  Salary") at the annual rate of Two Hundred  Sixty  Thousand
Dollars   ($260,000)  during  each  calendar  year  of  the  Term,   payable  in
substantially  equal monthly  installments (or such other more frequent times as
executives of the Company  normally are paid). In addition,  the Company's Board
of  Directors  or Option and  Compensation  Committee  of the Board of Directors
shall, in good faith,  consider  granting  increases in the Base Salary based on
such factors as Executive's  performance and the growth and/or  profitability of
the Company, but the Company shall have no obligation to grant such increases in
compensation.

               (b) BONUS PAYMENTS.  Executive  shall be entitled to receive,  in
addition  to the Base  Salary,  such  bonus  payments,  if any,  as the Board of
Directors or the Option and Compensation Committee of the Board of Directors may
specify.

               (c)  EXPENSES.  During  the  term  of his  employment  hereunder,
Executive shall be entitled to receive prompt  reimbursement  for all reasonable
expenses  incurred  by him (in  accordance  with  the  policies  and  procedures
established  by the Board of  Directors  for its senior  executive  officers) in
performing  services  hereunder,   provided  that  Executive  properly  accounts
therefor in accordance with Company policy.

               (d) OTHER BENEFITS. The Company shall not make any changes in any
employee  benefit  plans or other  arrangements  in effect on the date hereof or
subsequently  in  effect  in  which   Executive   currently  or  in  the  future
participates (including,  without limitation,  each pension and retirement plan,
supplemental pension and retirement plan, savings and profit sharing plan, stock
or unit ownership plan,  stock or unit purchase plan, stock or unit option plan,
life insurance plan,  medical  insurance  plan,  disability  plan,  dental plan,
health-and-accident  plan, or any other similar plan or arrangement)  that would
adversely affect Executive's rights or benefits  thereunder,  unless such change
occurs  pursuant to a program  applicable  to all  executives of the Company and
does not  result in a  proportionately  greater  reduction  in the  rights of or
benefits to  Executive  as compared  with any other  executive  of the  Company.
Executive  shall be entitled to  participate  in or receive  benefits  under any
employee benefit plan or other  arrangement made available by the Company now or
in the future to its senior  executive  officers and key  management  employees,
subject to and on a basis  consistent  with the terms,  conditions,  and overall
administration of such plan or arrangement.  Nothing paid to Executive under any
plan or arrangement presently in effect or made available in the future shall be
deemed  to be in lieu of the  Base  Salary  payable  to  Executive  pursuant  to
paragraph (a) of this Section 3.

               (e)  VACATIONS.  Executive  shall be  entitled  to ten (10)  paid
vacation days for the period from the date of this  Agreement  through  December
31, 1999.  Executive shall be entitled to twenty (20) paid vacation days in each
calendar year commencing on or after January 1, 2000, or such additional  number
as may be determined by the Board of Directors  from time to


                                       3


time.  For purposes of this Section 3(e),  weekends  shall not count as vacation
days and  Executive  shall also be  entitled to all paid  holidays  given by the
Company to its senior executive officers.

               (f)  PERQUISITES.  Executive  shall be  entitled  to receive  the
perquisites and fringe benefits appertaining to senior executive officers of the
Company in accordance  with any practice  established by the Board of Directors.
In  the  event  Executive's  employment  hereunder  is  terminated  (whether  by
Executive  or the  Company) for any reason  whatsoever  (other than  Executive's
death), then the Company shall, at Executive's written request and to the extent
permitted by the terms of such policies and applicable law, assign and convey to
Executive any life insurance  policies  maintained by the Company on the life of
Executive,  who shall thereafter be solely responsible,  at his election, to pay
all  premiums  payable  after such  assignment  and  conveyance  to maintain the
coverage under such policies with respect to Executive.  Executive  shall not be
required  to pay any  money or other  consideration  to the  Company  upon  such
assignment  and  conveyance,  it being  acknowledged  and agreed by the  parties
hereto that Executive's  execution and delivery hereof  constitute  adequate and
satisfactory consideration for such assignment and conveyance.

               (g) PRORATION.  Excepting only payments  pursuant to Section 3(b)
for  calendar  year 1999  (which  payments  shall be based upon a full  calendar
year), any payments or benefits payable to Executive hereunder in respect of any
calendar  year during  which  Executive is employed by the Company for less than
the  entire  year,   unless  otherwise   provided  in  the  applicable  plan  or
arrangement,  shall be  prorated in  accordance  with the number of days in such
calendar year during which he is so employed.

        4. EXECUTIVE'S OFFICE AND RELOCATION.  Executive shall primarily perform
his duties and  responsibilities  hereunder at the Company's  offices located at
5080  Spectrum  Drive,  Addison,  Texas (or at such  other  location  within the
Dallas,  Texas,  metropolitan  area,  to which  the  Company  may in the  future
relocate such  principal  executive  offices),  except for  reasonable  required
travel on the Company's  business.  If the Company requests  Executive to report
for the performance of his services hereunder on a regular or permanent basis at
any location or office more than thirty-five (35) miles from the office location
described in the first sentence of this Section 4, and Executive  agrees to such
change,  the Company  shall pay  Executive's  reasonable  relocation  and moving
expenses,  including,  but not  limited  to,  the cost of moving  his  immediate
family,  expenses  incurred  while  seeking  new  housing  (including  travel by
Executive's  spouse) and temporary living expenses  incurred by Executive or his
family for up to one hundred eighty (180) days.

essential functions of his duties and responsibilities  hereunder on a full time
basis for one hundred eighty (180) consecutive  calendar days, and within thirty

not have  returned to the  performance  of his  material  managerial  duties and
responsibilities  hereunder  on a full time basis,  the  Company  may  terminate
Executive's employment hereunder.

               (c) CAUSE. Subject to the provisions of Section 7(d), the Company

designated in a notice filed with the Company prior to Executive's death, or, if
no such person shall be designated,  to his estate as a death benefit,  his Base
Salary to the date of his death in addition to any payments  Executive's spouse,
beneficiaries,  or estate may be entitled to receive  pursuant to any pension or
employee benefit plan or other  arrangement or life insurance policy  maintained
by the Company. In addition,  (x) the Company shall make payments of premiums to
continue the medical and dental  insurance  coverage of  Executive's  spouse and
children  under  age  twenty-five  (25) as in  effect  at and as of the  date of
Executive's  death (or to provide as similar  coverage as possible  for the same
premiums if the continuation of existing  coverage is not permitted) for one (1)
year  after  the date of  Executive's  death,  in each case to the  extent  such
coverage is available, and (y) the Company shall make a lump sum cash payment to
the appropriate  insurance  company(ies)  in an amount  sufficient to fully fund

OccuSystems, Inc.

               (b) DISABILITY. During any period that Executive fails to perform
his material  managerial  duties and  responsibilities  hereunder as a result of
incapacity  due to  physical  or mental  illness,  Executive  shall  continue to

such termination, the Company shall pay to Executive, on or before the fifth day
following the Date of Termination  (as  hereinafter  defined) his Base Salary to
the Date of  Termination.  In addition,  (x) the Company  shall make payments of

company(ies)  in an amount  sufficient  to fully fund  future  premium  payments
pursuant to  Executive's  then existing  second-to-die,  split-dollar  insurance
policy(ies) obtained through the Company and/or OccuSystems, Inc.

RENEW.  If  (1) in  breach  of  this  Agreement,  the  Company  shall  terminate
Executive's  employment  (it being  understood  that a purported  termination of
Executive's  employment  by the  Company  pursuant  to  any  provision  of  this
Agreement that is disputed and finally  determined not to have been proper shall
be a termination by the Company in breach of this  Agreement),  or (2) Executive
shall  terminate his employment  for Good Reason,  or (3) the Company shall give
Executive  notice  pursuant  to Section 1 prior to any  anniversary  of the date
hereof that the Term of this Agreement shall not be  automatically  extended for
an  additional  year on any such  anniversary  date,  then the Company shall pay
Executive:

                      (A) his Base Salary through the Date of Termination at the

severance  pay to  Executive  on or before the fifth day  following  the Date of
Termination  and on the fifth day of each of the eleven (11)  months  thereafter
(amounting  to a  total  of  twelve  (12)  months),  an  amount  in  cash  equal
one-twelfth  (1/12) of  Executive's  annual Base Salary at the rate in effect at
the time the Notice of Termination is given; and

                      (C) all benefits  payable  under the terms of any employee
benefit plan or other arrangement as of the Date of Termination.

               In addition,  (x) the Company  shall make payments of premiums as
necessary to cause  Executive  and  Executive's  spouse and  children  under age
twenty-five  (25) to continue to be covered by the medical and dental  insurance
as in effect at and as of the Date of  Termination  (or to  provide  as  similar
coverage  as possible  for the same  premiums  if the  continuation  of existing
coverage is not  permitted) for one (1) year after the Date of  Termination,  in
each case to the extent such  coverage is  available,  and (y) the Company shall
make a lump sum cash payment to the  appropriate  insurance  company(ies)  in an
amount  sufficient to fully fund future premium payments pursuant to Executive's
then existing second-to-die, split-dollar insurance policy(ies) obtained through
the Company and/or OccuSystems, Inc.

               (e)  MITIGATION.  Executive shall not be required to mitigate the
amount of any payment provided for in this Section 6 by seeking other employment
or  otherwise;   provided,  HOWEVER,  that,  anything  herein  to  the  contrary
notwithstanding, in the event of the termination of Executive's employment prior
to a Change in Control (as defined in the  Concentra  Managed Care,  Inc.,  1997
Long-Term  Incentive Plan) which occurs after the consummation of the Merger (as
defined in that certain Amended and Restated Agreement and Plan of Merger, dated
as of March 24,  1999,  by and  between  Yankee  Acquisition  Corp.,  a Delaware
corporation,  and the Company)  (but not if  Executive's  employment  terminates
after such a Change in Control),  the amount of any payment  pursuant to Section
6(d)(B) and/or  pursuant to the first paragraph of



                                       8


Section  6(f) shall be reduced by any  compensation  earned by  Executive as the
result of  employment  by another  employer  (whether  as a  director,  officer,
employee,  manager,  owner,  consultant,   independent  contractor,  advisor  or
otherwise)  after  the Date of  Termination  until the end of the  twelve  month
period of clause (B) of Section 6(d) above.

               (f)  ADDITIONAL   REASON.   If  Executive   shall  terminate  his
employment for Additional Reason, as well as for Good Reason,  then, in addition
to and not in lieu of any other  amounts  payable by the  Company  to  Executive
whether  pursuant to Section  6(d) or otherwise  (it being the  intention of the
parties  that,  upon  the  occurrence  of an event or  events  described  in the
definition or "Good Reason" and "Additional  Reason" in Section 5(d),  Executive
may terminate this Agreement for Good Reason AND for  Additional  Reason),  then
the Company shall pay Executive as  additional  severance  pay, on or before the
fifth  day  following  the  Date of  Termination,  a lump  sum in cash  equal to
Executive's full annual Base Salary at the rate in effect at the time the Notice
of  Termination is given (for a total of two (2) times  Executive's  full annual
Base Salary when combined with amounts payable pursuant to Section 6(d)(B)).

               In  addition,  the  Company  shall make  payments  of premiums as
necessary to cause  Executive  and  Executive's  spouse and  children  under age
twenty-five  (25) to continue to be covered by the medical and dental  insurance
as in effect at and as of the Date of  Termination  (or to  provide  as  similar
coverage  as possible  for the same  premiums  if the  continuation  of existing
coverage  is not  permitted)  for one (1) year in  addition  to the one (1) year
provided for under Section 6(d) (for a total of two (2) years) after the Date of
Termination, in each case to the extent such coverage is available.

        7.     OTHER PROVISIONS RELATING TO TERMINATION.

               (a)  NOTICE  OF  TERMINATION.   Any  termination  of  Executive's
employment by the Company or by Executive (other than termination because of the
death of Executive)  shall be  communicated  by written Notice of Termination to
the  other  party  hereto.  For  purposes  of  this  Agreement,   a  "Notice  of
Termination"  shall mean a notice which shall indicate the specific  termination
provision in this Agreement relied upon and shall set forth in reasonable detail
the facts and  circumstances  claimed  to  provide  a basis for  termination  of
Executive's employment under the provision so indicated.

               (b) DATE OF TERMINATION. For purposes of this Agreement, "Date of
Termination"  shall mean:  (1) if  Executive's  employment  is terminated by his
death,  the date of his  death;  (2) if  Executive's  employment  is  terminated
because of a disability  pursuant to Section  5(b),  then thirty (30) days after
Notice of Termination is given  (provided that Executive shall not have returned
to the  performance  of his duties on a full-time  basis during such thirty (30)
day period);  (3) if  Executive's  employment  is  terminated by the Company for
Cause or by  Executive  for Good  Reason  and/or for  Additional  Reason,  then,
subject  to  Sections  7(c)  and  7(d),  the date  specified  in the  Notice  of
Termination;  (4) if the Company gives  Executive  notice  pursuant to Section 1
prior to any  anniversary  of the date  hereof  that the Term of this  Agreement
shall  not  be  automatically  extended  for an  additional  year  on  any  such
anniversary  date, the date upon which



                                       9


the Term expires; and (5) if Executive's  employment is terminated for any other
reason, the date on which a Notice of Termination is given.

               (c) GOOD REASON AND/OR ADDITIONAL REASON.  Upon the occurrence of
an event described in clauses (A) through (E) of the definition of "Good Reason"
in Section 5(d), and/or upon the occurrence of an event described in clauses (A)
through (D) of the definition of "Additional Reason" in Section 5(d),  Executive
may terminate his employment hereunder for Good Reason and/or Additional Reason,
as  applicable,  within one hundred  eighty  (180) days  thereafter  by giving a
Notice of  Termination  to the  Company  to that  effect.  If the  effect of the
occurrence  of the event  giving rise to Good Reason  and/or  Additional  Reason
under Section 5(d) may be cured,  the Company shall have the opportunity to cure
any  such  effect  for a  period  of  thirty  (30)  days  following  receipt  of
Executive's Notice of Termination. If the Company fails to cure any such effect,
the termination for Good Reason and/or  Additional Reason shall become effective
on the date specified in Executive's  Notice of  Termination.  If Executive does
not give such Notice of  Termination  to the Company,  then this  Agreement will
remain in effect; PROVIDED,  HOWEVER, that the failure of Executive to terminate
this  Agreement for Good Reason and/or  Additional  Reason shall not be deemed a
waiver of  Executive's  right to terminate his employment for Good Reason and/or
Additional Reason upon the occurrence of a subsequent event described in Section
5(d) in accordance with the terms of this Agreement.

               (d) CAUSE. In the case of any termination of Executive for Cause,
the Company will give Executive a Notice of Termination describing in reasonable
detail, the facts or circumstances giving rise to Executive's  termination (and,
if  applicable,  the action  required  to cure same) and will  permit  Executive
thirty  (30)  days  to cure  such  failure  to  comply  or  perform.  Cause  for
Executive's  termination will not be deemed to exist until the expiration of the
foregoing  cure period,  so long as Executive  continues to use his best efforts
during  the cure  period  to cure  such  failure.  If  within  thirty  (30) days
following  Executive's  receipt of a Notice of Termination for Cause,  Executive
has not cured the facts or circumstances giving rise to Executive's  termination
for Cause,  then Executive's  termination for Cause shall be effective as of the
date specified in the Notice of Termination.

               (e)  INTEREST.  Until paid,  all past due amounts  required to be
paid by the Company under any provision of this Agreement shall bear interest at
the highest  non-usurious rate permitted by applicable federal,  state, or local
law.

        8.     SUCCESSORS; BINDING AGREEMENT.

               (a)  SUCCESSORS.  This Agreement shall be binding upon, and inure
to the benefit of, the  Company,  Executive,  and their  respective  successors,
assigns, personal and legal representatives,  executors, administrators,  heirs,
distributees, devisees, and legatees, as applicable.

               (b) ASSUMPTION.  The Company will require any successor  (whether
direct or indirect, by purchase of securities,  merger,  consolidation,  sale of
assets,  or otherwise) to all or substantially  all of the business or assets of
the Company,  by an agreement in form and substance



                                       10


reasonably  satisfactory to Executive, to expressly assume this Agreement and to
agree to perform  this  Agreement in the same manner and to the same extent that
the  Company  would be required  to perform it if no such  succession  had taken
place.   Failure  of  the  Company  to  obtain  such  agreement   prior  to  the
effectiveness  of any such  succession  shall be a breach of this  Agreement and
shall entitle  Executive to compensation from the Company in the same amount and
on the same terms as he would be  entitled to  hereunder  if he  terminated  his
employment for Good Reason (and, if such  succession  occurs on or before August
17,  2000,  in the same  amount and on the same terms as he would be entitled to
hereunder if he terminated his employment  for Additional  Reason),  except that
for  purposes  of  implementing  the  foregoing,  the  date on  which  any  such
succession becomes effective shall be deemed the Date of Termination.

               (c) CERTAIN  PAYMENTS.  If Executive should die while any amounts
would still be payable to him  hereunder if he had  continued to live,  all such
amounts,  unless otherwise provided herein, shall be paid in accordance with the
terms of this Agreement to Executive's  devisee,  legatee, or other designee or,
if there be no such designee, to Executive's estate.

        9.  NOTICE.  For purposes of this  Agreement,  all notices and all other
communications  provided for in this Agreement  shall be in writing and shall be
deemed  to have been  duly  given  when (a)  delivered  personally,  (b) sent by
facsimile or similar electronic device and confirmed, (c) delivered by overnight
express, or (d) if sent by any other means, upon receipt.  Notices and all other
communications provided for in this Agreement shall be addressed as follows:

               If to Executive:

or to such other  address  as either  party may have  furnished  to the other in
writing in accordance herewith.

        10.  MISCELLANEOUS.  No  provision  of this  Agreement  may be modified,
waived, or discharged unless such waiver,  modification,  or discharge is agreed
to in a written  instrument  signed by Executive  and the Company.  No waiver by
either party hereto of, or compliance  with,  any condition or provision of this
Agreement  to be  performed  by such  other  party  shall be  deemed a waiver of
similar or  dissimilar  provisions  or conditions at the same or at any prior or
subsequent time. No agreements or representations, oral or otherwise, express or
implied,  with  respect to the  subject  matter  hereof have been made by either
party  which  are not set  forth  expressly  in this  Agreement.  The  validity,
interpretation,  construction,  and  performance  of  this  Agreement  shall  be
governed  by the laws of the  State of  Delaware,  excluding  any  choice-of-law
provisions thereof.

        11.  ATTORNEY  FEES.  All legal fees and costs  incurred by Executive in
connection  with  the  resolution  of any  dispute  or  controversy  under or in
connection  with this Agreement  shall be reimbursed by the Company to Executive
as bills for such  services are  presented  by Executive to the Company,  unless
such dispute or  controversy  is found to have been brought not in good faith or
without merit by a court of competent jurisdiction.

        12.  VALIDITY.  The invalidity or  unenforceability  of any provision or
provisions of this Agreement shall not affect the validity or  enforceability of
any other  provision  of this  Agreement,  which shall  remain in full force and
effect.

        13.   COUNTERPARTS.   This   Agreement   may  be   executed  in  several
counterparts,  each of which shall be deemed to be an original, but all of which
together will constitute one and the same agreement.

        14. ENTIRE AGREEMENT; EFFECTIVENESS. This Agreement shall be of no force
or effect  unless and until the  consummation  of the Merger (as defined in that
certain Amended and Restated Agreement and Plan of Merger, dated as of March 24,
1999, by and between Yankee Acquisition Corp., a Delaware  corporation,  and the
Company,  as such  agreement  may be  amended  from  time to  time);  upon  such
consummation,  this Agreement shall be in full force and effect.  This Agreement
constitutes the entire agreement between the parties with respect to the subject
matter  hereof  and  supersedes  in all  respects  any and all prior  employment
agreements  and/or severance  protection  letters,  agreements,  or arrangements
between Executive,  on the one hand, and the Company or any other predecessor in
interest  thereto or any of their  respective  subsidiaries,  on the other hand,
which  prior  employment   agreements  and/or  severance   protection   letters,
agreements,  and  arrangements,  if any, are hereby  cancelled and of no further
force or effect.

        15. RIGHT AND OPTION OF COMPANY TO REPURCHASE SHARES UPON TERMINATION OF
Employment.

               (a) In the event that, prior to an initial public offering of the
Company's  equity  securities,   Executive's  employment  with  the  Company  is
terminated  for any  reason,  the  Company



                                       12


shall thereupon have the right and option,  but not the obligation,  to purchase
from Executive all or any part of the shares of common stock, par value $.01 per
share,  of  the  Company  (the  "Shares")  held  by  Executive  as of  the  date
Executive's employment so ceases at a purchase price equal to the greater of (1)
Sixteen and 50/100 Dollars ($16.50) per Share, and (2) the fair market value (as
hereinafter  defined) of such Shares as of the date  Executive's  employment  so
ceases.

               (b) The Company  may  exercise  the right and option  provided in
Section  15(a) above by giving  Executive a written  notice of such  election to
purchase  at any time  within  ninety  (90)  days  after  the  date  Executive's
employment  so ceases.  The closing for the  purchase by the Company of any such
Shares  pursuant to the provisions of said Section 15(a) shall take place at the
offices of the Company on the date specified in such written notice,  which date
shall be a  business  day not later  than  sixty  (60) days  after the date such
notice  is  given.  At such  closing,  Executive  will  deliver  or  cause to be
delivered  such Shares,  duly  endorsed  for  transfer,  against  payment of the
applicable  purchase  price  therefor.  Such purchase  price shall be payable to
Executive  in cash or other  immediately  available  funds.  To the  extent  the
Company  chooses not to exercise  such right and option under said Section 15(a)
to purchase any Shares,  such Shares shall  thereupon cease to be subject to the
provisions of this Section 15.

               (c) For the purposes of this Agreement,  "fair market value" of a
Share as of any date shall mean the value of such  stock as  determined  in good
faith by the Board of  Directors of the Company on a basis  consistent  with the
manner of  determining  the fair market value of the Company's  common stock for
purposes of offering the Company's common stock to equity investors.

        IN WITNESS  WHEREOF,  the parties have executed this Agreement as of the
date and year first above written.
