                  the options, as follows:



                                     - 4 -

           6.2    Dr. Thornton will be eligible to be awarded further stock
                  options annually in accordance with Phoenix International's
                  WORLDWIDE EXECUTIVE REMUNERATION PLAN. The number of such
                  options currently authorized by Phoenix International's Board
                  of Directors is equal to 50% of the salary Dr. Thornton earned
                  in the previous fiscal year, divided by the option exercise
                  price. Subject to amending the KEY EMPLOYEE SHARE OPTION PLAN
                  and obtaining shareholder and regulatory approval, these
                  options will vest 20% for each year of continuous service
                  subsequent to their granting. If shareholder or regulatory
                  approval are not received for this vesting schedule, these
                  options will vest as provided for by the KEY EMPLOYEE SHARE
                  OPTION Plan.

           6.3    The exercise price of all stock options shall be the price
                  provided for by the KEY EMPLOYEE SHARE OPTION PLAN.

           6.4    Subject to the CHANGE IN CONTROL AGREEMENT attached hereto as
                  SCHEDULE E and which is executed concurrently herewith (the
                  "CHANGE IN CONTROL AGREEMENT"), if Dr. Thornton's employment
                  is terminated before the fifth anniversary of the granting of
                  options in the year 2003, Dr. Thornton will have 60 days,
                  after her employment ceases to exercise vested options.
                  Subsequent to this 60 days, all options will expire
                  automatically.

           6.5    Dr. Thornton and Phoenix agree that the other terms and
                  conditions of the KEY EMPLOYEE SHARE OPTION PLAN, shall apply
                  to the options held by her, save that in the event of a
                  proposed change of control of Phoenix International, including
                  under a takeover bid, or any of the other circumstances
                  covered by the CHANGE IN CONTROL AGREEMENT, the terms and
                  conditions of the CHANGE IN CONTROL AGREEMENT concerning the
                  vesting and exercisability of the options shall apply and
                  override the provisions hereof and of the KEY EMPLOYEE SHARE
                  OPTION PLAN, providing they are not less favorable than those
                  contained herein.

           6.6    All grants of stock options are conditional on signature of
                  the attached CONFIDENTIALITY, PROPRIETARY RIGHTS, REGULATORY
                  COMPLIANCE AND NON-COMPETITION AGREEMENT (SCHEDULE F ATTACHED)
                  that requires, among other things, that Dr. Thornton not
                  compete with Phoenix International for one year after
                  voluntarily leaving the company or being terminated for a
                  serious reason pursuant to Article 8 of this Agreement.

                  8.1.1 Phoenix may terminate this Employment Agreement at any
                        time, for a serious reason, by resolution of its Board
                        of Directors adopted at a duly constituted meeting of
                        the Board. If Phoenix exercises its rights to terminate
                        this Employment Agreement for a serious reason, Dr.

                        benefits (but not bonuses), accrued as at the date of
                        termination. For the purposes of this agreement, a
                        "serious reason" shall mean that Dr.
                        Thornton:

                        (a) has refused, without valid reason, to comply with
                         the reasonable instructions of the Board of Directors
                         or the CEO of Phoenix International given to her in her
                         capacity as an executive of Phoenix insofar as such
                         instructions are not inconsistent with the terms of
                         this Agreement;

                        (b) has committed improper misconduct which is
                         materially detrimental to Phoenix, or has been grossly
                         negligent in the performance of her duties hereunder;

                        (c) commits wrongful acts against the interests of
                         Phoenix International or against its property;

                        (d) becomes subject in any way to bankruptcy or 
                            insolvency laws;



                                     - 6 -



                        (e) commits and is found guilty of an indictable
                         criminal offence or other similar offence involving
                         fraudulent or dishonest conduct, by a court of
                         competent jurisdiction; or

                        (f) gives cause to Phoenix International for a serious
                         reason similar in gravity to those set forth above.


           8.2    TERMINATION BY PHOENIX WITHOUT A SERIOUS REASON  

                  8.2.1  Phoenix may also terminate this agreement at its
                         discretion for any reason whatsoever by giving Dr.
                         Thornton 12 weeks prior notice of its decision to
                         dismiss. Phoenix may, at any time during the notice
                         period, choose to immediately discharge Dr. Thornton,
                         but in this case Dr. Thornton shall be entitled to
                         receive and shall be paid all amounts which she would
                         otherwise earn during the notice period.

                  8.2.2  If Phoenix terminates this agreement at its
                         discretion, without a serious reason, Phoenix shall
                         pay Dr. Thornton an amount equal to her gross base
                         annual salary (at the time of notification of
                         termination) divided by 12 and multiplied by the
                         number of years of employment (not less than one (1))
                         Dr. Thornton has been employed by Phoenix
                         International or any of its subsidiaries. All
                         appropriate withholding as may be required by law
                         will be deducted from the amount so calculated. The
                         starting date of employment for the purpose of
                         calculating the payment due hereunder is January 27,
                         1992. This payment shall be made within 7 days after
                         the last day Dr. Thornton is employed. The bonus for
                         the fiscal year in which termination takes place, if
                         any, will be paid pro rata to the number of days
                         worked in the fiscal year. With the exception of the
                         amount referred to aforesaid, Dr. Thornton shall have
                         no right to be paid or to claim any further payments
                         related to or arising out of the termination of her
                         employment by Phoenix and she renounces to any such
                         further right or claim.

                  8.2.3  Phoenix's obligation to make the aforesaid payments
                         will not be reduced or affected if Dr. Thornton has
                         secured alternative employment.

           8.3    TERMINATION BY DR. THORNTON  

                  8.3.1 Dr. Thornton may, at her option, terminate this
                  agreement for any reason whatsoever provided that Phoenix is
                  given at least 90 days notice before said termination becomes
                  effective.



                                     - 7 -


                  8.3.2 Dr. Thornton has the right to terminate this agreement
                  if constructively dismissed, and receive compensation
                  according to the terms and conditions of section 8.2, above.
                  Dr. Thornton shall be considered to have been constructively
                  dismissed if a) there is a material and adverse diminution on
                  an accumulative basis of her duties, authority, position,
                  compensation, benefits, or title, which is not applied to all
                  other executives of Phoenix International, (b) she is required
                  to move her home or residence anywhere other than in the
                  municipality or metropolitan area in which her office and
                  residence currently exist; or (c) there is a breach by Phoenix
                  of any of the material terms of this Agreement.

                  (within the meaning of and as such terms are defined in the

                  CHANGE IN CONTROL AGREEMENT with respect to termination of
                  employment shall override the provisions hereof to the extent
                  and provided that they are no less favourable than those
                  herein contained.


10.        CONFIDENTIAL INFORMATION / NON-COMPETITION AND OTHER UNDERTAKINGS

           10.1   Dr. Thornton shall sign concurrently herewith the

                  RIGHTS, REGULATORY COMPLIANCE AND NON-COMPETITION AGREEMENT,
                  having had ample opportunity to review same and consult
                  counsel, if desired. Subject to Section 12 of this Employment
                  Agreement, Dr. Thornton recognizes that, consistent with
                  Phoenix International's policies for all of its executives and
                  senior managers who have equity in the company or who receive
                  stock options, this agreement binds Dr. Thornton to
                  non-competition restrictions for one year after her employment
                  with Phoenix ceases if she voluntarily leaves Phoenix or is
                  terminated for a serious reason pursuant to Article 8.1 of
                  this Agreement..

           10.3   With respect to the non-competition provisions included in the
                  CONFIDENTIALITY, PROPRIETARY RIGHTS, REGULATORY COMPLIANCE AND
                  NON-COMPETITION AGREEMENT, which are applicable after
                  cessation of employment of Dr. Thornton by Phoenix, it is
                  understood and agreed by both Parties that the purpose of
                  these 



                                     - 8 -



                  provisions is to ensure that Dr. Thornton does not join a CRO
                  or any other organization offering similar services or
                  software products to those provided by Phoenix International,
                  for a period of one (1) year subsequent to the termination of
                  her employment at Phoenix if she voluntarily leaves Phoenix or
                  is terminated for a serious reason pursuant to Article 8.1 of
                  this Agreement. Thus, Dr. Thornton would be free to work for
                  any biotechnology or pharmaceutical company which does not
                  offer similar services or software products to those provided
                  by Phoenix International.


11.        INCENTIVES SUBJECT TO CHANGE

                  International's executive share option plans, bonus plans and
                  other incentives are subject to future revision by Phoenix
                  International's Board of Directors, and that if such revisions
                  conflict with this Employment Agreement, the revisions to the
                  incentive plans shall prevail and shall replace anything to
                  the contrary contained in this agreement, provided such
                  revisions shall have no effect on share options already issued
                  to Dr. Thornton. Furthermore, such revisions, if made, shall
                  not be a cause for constructive dismissal notwithstanding any
                  other provision of this agreement.


12.        SURVIVAL OF RESTRICTIVE COVENANTS  

           12.1   The parties agree that the undertakings of Dr. Thornton under

                  REGULATORY COMPLIANCE AND NON-COMPETITION AGREEMENT, shall
                  only survive termination of this agreement in accordance with
                  their respective terms, in the event that Dr. Thornton's
                  employment is terminated by Phoenix for a serious reason
                  and/or following Dr. Thornton's resignation (if such
                  resignation does not follow a Change of Control or a
                  constructive dismissal),


13.        DAMAGES

                  $100,000, which amount shall not be reduced for partial

                  invalid, for any reason whatsoever, such unenforceability or
                  invalidity will not affect the enforceability or validity of

                  or provision, nor shall it be considered a consent to or
                  waiver of any other then existing or subsequent breach of a
                  different term or provision.
