               event that the Board desires to seek  protection on behalf of the
               Company thereafter.

          3.2  Covenant Not To Compete.  In consideration of the consummation of
               the  transactions  contemplated  under this Agreement,  Executive
               hereby  covenants and agrees that for the period beginning on the
               date   hereof   and  ending  one  (1)  year  after  the  Date  of
               Termination,  Executive will not,  alone or in  association  with
               others,  either as a principal,  agent, direct or indirect owner,
               shareholder,   partner,   joint  venturer  or  member,   officer,
               director, employee, lender, investor, consultant,  manager, or in
               any other capacity:

               (a)  Recruit or hire any  employee of the  Company,  or otherwise
                    attempt to solicit or induce any  employee of the Company to
                    leave the employment of the Company.

               (b)  Solicit any customer or Prospective  Customer of the Company
                    or  otherwise  interfere  with  the  business  relationships
                    between the Company, its customers,  Prospective  Customers,
                    suppliers  and others  with whom the  Company  conducts  its
                    Clinical Research Services business.

               (c)  Perform any service for any customer or Prospective Customer
                    of the  Company  which is  competitive  in any  manner  with
                    Clinical Research Services which the Company may perform for
                    such  customers  or  Prospective  Customers,  regardless  of
                    whether the Company has or is now  providing  such  Clinical
                    Research Services.

               (d)  Executive  shall not  directly  or  indirectly  solicit  for
                    employment on  Executive's  own behalf,  or on behalf of any
                    other  enterprise,  any  individual  who is or has  been  an
                    employee,  agent or independent contractor of the Company in
                    a  capacity  related  or  pertaining  to  Clinical  Research
                    Services.

     This  covenant  not to  compete  shall in no way  restrict  the  rights  of
Executive to hold 5% or less of the equity  securities of any corporation  whose
equity securities are listed on a national  securities exchange or are regularly
traded in the over-the-counter  market and for which quotations are available on
the National Association of Securities Dealers Automated Quotation System.

          3.3  Confidentiality.  Executive  acknowledges  that, by virtue of his
               involvement with the Company, he has been, and in the future will
               be,  exposed to and has had access,  and, in the future will have
               access, to trade secrets, processes, computer programs, financial
               data   and   information,    marketing   information,    customer
               information,  pricing  information,  customer lists,  information


                                      141

               relating  to the  business or  operations  of the Company and any
               other  information,  software,  equipment or processes  which are
               used in connection  with or relate to the Company or its members,
               managers,  employees,  customers  or other  vendors  or which are
               otherwise  proprietary  to or in the  possession  of the  Company
               ("Confidential   Information")  except  where  such  Confidential
               Information (i) was or becomes generally  available to the public
               other  than  as a  result  of a  disclosure  by  Company  or  its
               affiliates to one or more unauthorized  parties, (ii) is required
               by law to be  disclosed or (iii) is made  generally  available to
               the public by the Company.  Executive  further  acknowledges that
               his  expertise,  knowledge  and  experience  in,  of and with the
               Company  would  enable  him to use such  information  to  benefit
               individuals or entities other than the Company.  Executive hereby
               covenants and agrees as follows:

                    (a)  During  the  Term  and at  all  times  thereafter,  the
                         Confidential  Information shall be kept confidential by
                         Executive,  will  not be used in any  manner  which  is
                         detrimental   to  the  Company  or  its   shareholders,
                         members, managers or employees, and will be safeguarded
                         by Executive from  unauthorized  disclosure.  Executive
                         also agrees that  Executive will disclose to the Person
                         or Persons  designated by the Company all  Confidential
                         Information.

                    (b)  Following the  expiration of the Term,  Executive  will
                         return  to the  Company  any  Confidential  Information
                         currently  in his  possession  or  control or which may
                         subsequently come into his possession or control,  will
                         not retain any copies, including non-conforming copies,
                         thereof,  including,  without limitation, all analyses,
                         compilations,  studies or other  documents  in whatever
                         form,  including magnetic media,  prepared by Executive
                         or for  Executive's  use  containing or reflecting  any
                         Confidential Information.  Executive shall not disclose
                         to the Company, use in the Company's business, or cause
                         the Company to use,  any  confidential  or  proprietary
                         information or materials of any third party.

          3.4  Enforcement  by  Injunction.   Executive  acknowledges  that  the
               protections of the Company set forth in Sections 3.1, 3.2 and 3.3
               of this  Agreement  are of vital  concern  to the  Company,  that
               monetary  damages for any violation  thereof would not adequately
               compensate  the  Company  and that the  Company  is  engaged in a
               highly competitive business.  Accordingly,  Executive agrees that
               the  restrictions  set  forth in  Sections  3.1,  3.2 and 3.3 are
               reasonable and that, in addition to any other remedy, the Company
               shall be entitled to enforce such Sections by injunction  whether
               or not Executive's employment hereunder has terminated. Executive
               hereby waives any  requirement of a bond for such  enforcement by
               injunction.

          3.5  Early  Termination of  Restrictive  Provisions.  The  restrictive


                                      142

               covenant  set  forth  in  Section  3.2 of  this  Agreement  shall
               terminate  immediately upon the occurrence of (i) any termination
               of Executive not for Cause,  (ii) any  termination of Kirby under
               the Kirby  Employment  Agreement not for Cause, or (ii) an "Event
               of  Default"  under  any Note  which is due to PHC's  failure  or
               refusal  to pay  amounts  due to  Sellers  thereunder  which such
               failure or failures  continue for an aggregate period of not less
               than six (6) months during the Terms of any such Notes.

          3.6  Partial  Enforcement.  If any term or condition of this Agreement
               shall  be  invalid  or  unenforceable  to  any  extent  or in any
               application, then such term or condition shall automatically, and
               without  any  further  action,  be  reformed  so as to retain the
               fullest extent of any  restriction  therein  permitted by law and
               the  remainder  of this  Agreement,  and such term or  condition,
               except  to such  extent  or in  such  application,  shall  not be
               affected  thereby,  and each and every term and condition of this
               Agreement  shall be valid and enforced to the fullest  extent and
               in the broadest application permitted by law.

          3.7  Cumulative Rights. Each and all of the various rights, powers and
               remedies of the Company as set forth in this  Agreement  shall be
               considered  as  cumulative,  with and in  addition  to any  other
               rights, powers or remedies of such parties, and no one of them is
               exclusive  of the  others or is  exclusive  of any other  rights,
               powers and remedies  allowed by law or in equity.  The  exercise,
               partial  exercise  or  non-exercise  of  any  rights,  powers  or
               remedies shall  constitute  neither the election  thereof nor the
               waiver  of any other  rights,  powers or  remedies.  All  rights,
               powers and  remedies  of the  parties  hereto  shall  survive the
               termination of this Agreement.

          3.8  Merger or Reorganization. The Company may assign its rights under
               this  Agreement in accordance  with Section 10.10 of the Purchase
               Agreement.

          3.9  Enforcement.  Executive  agrees and warrants  that the  covenants
               contained  herein are reasonable,  that valid  consideration  has
               been and will be received  therefore and that the  agreements set
               forth herein are the result of arms-length  negotiations  between
               the parties hereto.  Executive  recognizes that the provisions of
               this  Article 3 are  important to the  continuing  welfare of the
               Company,  and that money damages are an inadequate remedy for any
               violation  thereof.   Accordingly,  in  the  event  of  any  such
               violation by Executive,  Pivotal or PHC, in addition to any other
               remedies  they may have,  shall have the right to  institute  and
               maintain a proceeding to compel specific  performance  thereof or
               to issue an  injunction  restraining  any action by  Executive in
               violation of this Article 3.

     4.   Termination of Employment.

          4.1  Death or Disability.  Executive's employment under this Agreement
               shall terminate upon his death or Disability.  Executive shall be
               deemed to be  Disabled  in the good  faith  determination  of the


                                      143

               Board. At any time and from time to time, upon reasonable request
               therefore by the Company,  Executive  shall submit to  reasonable
               medical examination for the purpose of determining the existence,
               nature  and  extent of any such  disability.  The  Company  shall
               promptly  give  Executive  notice  of any such  determination  of
               Executive's  Disability  and of the  decision  of the  Company to
               terminate Executive's  employment by reason thereof. In the event
               of  Disability,  until the Date of  Termination  the Base  Salary
               payable  to  Executive   under   Section  2.1  shall  be  reduced
               dollar-for-dollar by the amount of disability  benefits,  if any,
               paid to Executive in  accordance  with any  disability  policy or
               program of the Company.  "Disability" shall mean the inability of
               Executive,  by reason of any medically  determinable  physical or
               mental  impairment  for a period of 90 days  during  any 12 month
               period,  regardless of the Executive's presence or absence at his
               place of  employment,  to carry out and  perform  the  duties and
               obligations ordinarily required of Executive.

          4.2  Termination by the Company.

               (a)  With or Without Cause. The Company may terminate Executive's
                    employment  under  this  Agreement  with or  without  Cause.
                    "Cause"  means,  (i)  commission  of  any  dishonest  act by
                    Executive in  connection  with  Executive's  performance  of
                    activities  including,  without limitation,  but not limited
                    to, an act of fraud,  embezzlement  or  willful  breach of a
                    fiduciary   duty  to  the  Company,   (ii)   drunkenness  or
                    intoxication while engaged in Company business or the use of
                    drugs  or  alcohol  in  a  manner  which  adversely  affects
                    performance of the Executive's  activities,  (iii) diversion
                    of any corporate  opportunity of the Company for Executive's
                    direct or indirect benefit,  (iv) commission by Executive of
                    any  act  of  sexual  harassment,  discrimination  or  other
                    violation  of  any  similar  statute,   ordinance,   law  or
                    regulation  regarding human rights,  (v) any act or omission
                    by Executive which causes the  disqualification,  expiration
                    or termination  of the Company's  license which is issued by
                    any governmental or quasi  governmental  authority under any
                    statute  governing the business or operations of the Company
                    and which disqualification,  expiration or termination has a
                    Material  Adverse  Effect  upon  the  Company's  ability  to
                    conduct business,  (vi) the breach by Executive of Article 3
                    of this  Agreement,  or  (vii)  Executive's  failure  to use
                    commercially  reasonable efforts to perform his duties under
                    this  Agreement  and   Executive's   failure  to  cure  such
                    non-performance  within  thirty  (30)  calendar  days  after
                    receipt of written  notice from the Company  specifying  the
                    nature of such failure, or if such failure is not capable of
                    being cured  within  thirty (30)  calendar  days,  Company's
                    acceptance,   in  writing,  of  a  written  plan  of  action
                    submitted to the Company,  within ten (10)  calendar days of
                    receipt of such notice from the  Company,  that sets forth a
                    reasonable  plan  for  Executive's   cure  of  the  failure,
                    provided,   however,   that  two  or  more   occurrences  of
                    Executive's  failure to use commercially  reasonable efforts


                                      144

                    to perform his duties under this  Agreement  during the term
                    of this Agreement shall, at Company's option,  constitute an
                    immediate termination for Cause.

          4.3  Termination  by Executive.  Upon thirty days prior written notice
               Executive may terminate his employment  under this Agreement with
               or without Good Reason (as defined below). If such termination is
               with Good Reason,  Executive shall give the Board written notice,
               which shall identify with reasonable  specificity the grounds for
               Executive's  resignation.  For purposes of this Agreement,  "Good
               Reason"  shall  mean any of the  following:  (i) a  reduction  in
               Executive's  compensation  in  violation  of Section  2.1 of this
               Agreement,  which  reduction  is  accomplished  without the prior
               written  consent  of  Executive,  (ii) a material  diminution  in
               Executive's duties and responsibilities  under this Agreement for
               a period of one month or more other than by virtue of Executive's
               Disability, which material diminution is accomplished without the
               prior written consent of Executive, or the mutual written consent
               of Executive and Company, or the unilateral conduct of Executive,
               (iii) the failure to pay any of Executive's compensation when due
               (including any Bonus),  except in the case of Executive's  breach
               of this Agreement or any other agreement between  Executive,  the
               Company  or its  affiliates,  (iv) any  material  breach  of,  or
               material  failure  of  the  Company  to  perform,   any  material
               provision of this  Agreement  including,  but not limited to, the
               Bonus  provisions  contained  in  Sections  2.2 and 2.3,  and the
               failure  of  such   breaching   party  to  cure  such  breach  or
               non-performance  within the applicable "Cure Period",  or (v) any
               failure by PHC to fund the Company's working capital requirements
               in accordance with the terms and conditions and in the amount set
               forth in Section 3.5 of the  Purchase  Agreement,  which  failure
               would materially impair Executive's ability to perform the duties
               set forth in attached  Exhibit A. For purposes of this Agreement,
               the term "Cure Period" shall mean a period of time that commences
               upon the giving of written  notice by a  non-defaulting  party to
               the defaulting party(ies) that a breach or failure to perform has
               occurred  and expires ten (10)  calendar  days from the date such
               notice is given or deemed given.

          4.4  Date of Termination. "Date of Termination" shall mean the earlier
               of  (a)  the  expiration  of the  Term,  and  (b) if  Executive's
               employment is otherwise terminated whether by Executive or by the
               Board, the date on which Executive's  employment with the Company
               actually terminates.

          4.5  No Event of Default under Transaction Documents.  Any termination
               of this  Agreement by the Company or Executive  (whether  with or
               without  Cause and whether with or without Good Reason) shall not
               independently  constitute an event of default for purposes of the
               Transaction  Documents,  and no independent  action  initiated by
               Executive,  PHC  or  Pivotal  for  a  breach  of  the  terms  and
               conditions of this Agreement  shall give rise to a separate cause
               of action  under the  Transaction  Documents  except  the  rights
               specifically set forth in the Notes.

                                      145

     5.   Compensation Upon Termination.

          5.1  As a Result of Death, Disability, Cause or Resignation.

               (a)  Death  or  Disability.  Subject  to  Executive's  continuing
                    compliance with the terms of this Agreement,  if Executive's
                    employment  under this Agreement is terminated  prior to the
                    expiration of the Term by reason of his death or disability,
                    then  Executive  (or in the case of his death,  his personal
                    representative)  shall be  entitled to receive the amount of
                    his Accrued  Obligations (as defined below),  such amount to
                    be  paid in  accordance  with  the  Company's  ordinary  and
                    customary  payroll  practices.  As used  in this  paragraph,
                    "Accrued  Obligations" means, as of the Date of Termination,
                    (i) any payments which  Executive may be entitled to receive
                    pursuant to any Company  employee  benefits plan or program,

                    Executive's  employment  under this  Agreement is terminated
                    prior  to  the  expiration  of the  Term  by  reason  of his
                    termination  by the  Company  for  Cause or his  resignation
                    without Good Reason, then Executive shall solely be entitled
                    to receive the following  benefits:  (i) any benefits  which
                    Executive may be entitled to receive pursuant to any Company

          5.2  By Executive for Good Reason or the Company other than for Cause.

                    (a)  Benefits.  If,  prior to  scheduled  expiration  of the
                         Term,  the Company  terminates  Executive's  employment
                         without Cause,  or Executive  terminates his employment
                         for Good Reason, Executive shall be entitled to receive
                         the Accrued  Obligations  described  in Section  5.1(a)
                         and,   subject  to  Section   5.2(b),   the   following
                         additional  benefits  (such  additional  benefits,  the
                         "Post-Termination Benefits"):

                    (i)  In the event the  Company  terminates  the  Executive's
                         employment  without Cause or the  Executive  terminates
                         his   employment  for  Good  Reason,   then,   provided
                         Executive continues to comply with the terms of Section
                         3 of this Agreement, the Company shall pay to Executive
                         his Base Salary,  payable in accordance  with Pivotal's
                         regular payroll  practices (but no less frequently than

                         other  deductions  required  by law  and  other  normal

                                      146

                         the Date of Termination.  In addition,  Executive shall
                         have the right to select an executive placement firm to
                         provide executive  placement  services to Executive and
                         the Company  shall retain and pay directly all costs up
                         to $10,000 for such executive  placement services until
                         the earlier to occur of (i) the date on which Executive
                         starts new,  full time  employment,  or (ii) six months
                         from the Date of Termination.

                    (b)  Conditions  to  Receipt  of  Post-Termination  Benefits
                         under Section  5.2(a).  As a condition to receiving any
                         Post-Termination  Benefits  to  which  Executive  would
                         otherwise be entitled under Section  5.2(a),  Executive
                         shall execute a release (the "Release"),  in a form and
                         substance reasonably  satisfactory to the Board, of any
                         claims,  whether arising under Federal,  state or local
                         statute,  common law or otherwise,  against the Company
                         and its  direct  or  indirect  subsidiaries,  and their
                         respective  officers,  directors and stockholders which
                         arise or may have  arisen on or before  the date of the
                         Release, other than any claims arising under any of the
                         Transaction  Documents or any rights to indemnification
                         from  the   Company   and  its   direct   or   indirect
                         subsidiaries  pursuant to any  provisions  of Company's
                         (or   any  of   its   subsidiaries')   certificate   of
                         incorporation  or by-laws or any directors and officers
                         liability insurance policies maintained by the Company.
                         If Executive  fails or  otherwise  refuses to execute a
                         Release  within a reasonable  time after the  Company's
                         request to do so, Executive will not be entitled to any
                         Post-Termination Benefits. In addition, if, following a
                         termination of employment  that gives Executive a right
                         to the payment of Post-Termination Benefits,  Executive
                         engages in any activities that violate the covenants in
                         Section 3,  Executive  shall  have no further  right or
                         claim  to  any  Post-Termination   Benefits  and  shall
                         promptly repay any Post-Termination Benefits previously
                         received (such repayment to be in addition to any other
                         rights or remedies  available  to Company in respect of
                         such violation).

          5.3  No  Mitigation.  Executive  shall not be required to mitigate the
               amount of any payment or benefit  provided  for in this Section 5
               by  seeking  other  employment  or  otherwise,   and,  except  as
               otherwise  expressly provided in Sections 5.1 or 5.2, the amounts
               of compensation or benefits payable or otherwise due to Executive
               under this Section 5 or other  provisions of this Agreement shall
               not be reduced by compensation or benefits  received by Executive
               from any other employment he shall choose to undertake  following
               termination of his employment under this Agreement.
