                                      WITH
                                GIUSEPPE MIOZZARI

                              W I T N E S S E T H:

THIS  AMENDED  AND RESTATED EMPLOYMENT AGREEMENT ("Agreement") is  entered  into
effective  as of JUNE 9, 2000, by and between Heska AG, a corporation  organized
under  the laws of Switzerland with its principal office at Gruengenstrasse  19,
CH-4416  Bubendorf ("Company") and GIUSEPPE MIOZZARI ("Employee").  Company  and
Employee are collectively referred to herein as the "Parties."

WHEREAS,  effective  as of July 1, 1997, Company and Employee  entered  into  an
Employment Agreement, (the "Employment Agreement"); and

WHEREAS,  the  Parties desire to restate the Employment Agreement  for  ease  of
reference and to further amend said agreement for the purpose of making  certain
provisions more consistent with current Company practice.

NOW THEREFORE, in consideration of the foregoing, the Parties agree as follows:

A.   The Employment Agreement is hereby restated and amended as set forth below:

Whereas  Company desires to employ Employee to act as its MANAGING DIRECTOR  in
an at-will capacity; and

Whereas   Employee wishes to act as Company's MANAGING DIRECTOR as an  employee
in an at-will capacity;

NOW,  THEREFORE,  in  consideration  of the  mutual  covenants  and  warranties
contained herein, the parties agree as follows:

Employee hereby accepts such employment.

2.   Duties and Responsibilities.  Employee shall serve as MANAGING DIRECTOR of
Company,  with such duties and responsibilities as may be assigned to him  from
time  to  time  by his superior officers (the "Senior Management")  and/or  the
Board  of  Directors  of  Company,  and with such  on-going  daily  duties  and
responsibilities  as  are  typically entailed in  such  position.   The  Senior
Management and/or the Board of Directors shall be entitled to reasonably change
such title, duties and responsibilities from time to time, in their discretion.
Employee  shall  devote  his full time and energies to such  duties.   Employee
shall not be entitled to any special remuneration for overtime work.

3.    Compensation.  Company shall pay Employee, as compensation  for  services
rendered  under this Agreement, a "base salary" per year, the amount  of  which
shall initially be 322'711 SFr, which may be increased from time-to-time by the
Company  in its discretion.  If for any reason during any given year,  Employee
does  not  work  an  entire  year,  other than  normal  vacations  as  provided
hereunder, the compensation will be prorated to compensate only for the  actual
time worked.

4.    Expenses.   Company shall reimburse Employee for his  reasonable  out-of-
pocket  expenses incurred in connection with the business of Company, including
travel  away  from the Company's facilities, upon presentation  of  appropriate
written  receipts  and  reports  and subject to  the  customary  practices  and
limitations of Company.

5.    Employee Benefits.  During the term of his employment hereunder, Employee
shall  be  entitled  to receive the same benefits that the Board  of  Directors
establishes  generally for the officers and other employees of Company  and  as
comply  with  Swiss  law.   These  may include,  from  time  to  time,  medical
insurance, life insurance, paid vacation time and medical disability insurance.
In addition, Employee shall be entitled to the following additional benefits:

     (a)   Company  shall  bear 50% of the cost of pension  contributions  with
     respect  to  the full amount of Employee's base salary, including  amounts
     above  the statutory limit, with Employee to bear the balance, all in  the
     amounts set by the pension insurer selected by Company for others of  like
     age.

     (b)   Company shall bear the costs of leasing, insuring and maintaining  a
     car  (including gasoline) for the business and personal use  of  Employee,
     with the expected personal use not to exceed 25%.

     (c)   Employee's  base salary payable under Section  3  shall  include  an
     expense  base  allowance  of 24,000 SFr per year  for  Employee's  use  in
     accordance with reasonable policies to be adopted by Company.

6.   Termination.

     (a)   At-Will.  This is an at-will employment agreement and does not  bind
     either of the parties to any specific term or duration.

          (i)   This Agreement may be terminated by either party, for cause  or
          without  cause,  by giving one month prior written notice,  with  the
          effective  date  of termination to be on the last day  of  the  month
          following the month in which notice is given.

          (ii)  Notwithstanding Section 6(a)(i) above, each party may for valid
          reasons as defined in Article 337 of the Swiss Code of Obligations or
          any  successor  statute,  terminate this  Agreement at  any  time and
          without giving written notice to the other party.

     (b)  Termination "Without Cause" - Separation Benefits.

          (i)   Upon  "involuntary termination" of his employment with  Company
          for  other  than  a  "change of control",  as  defined  in  Paragraph
          6(c)(iii)  below, or by Employee as permitted under Section  6(a)(ii)
          above,  Employee  will be entitled to severance pay  as  provided  in
          Paragraph  6(b)(ii) below, unless he is terminated  for  "cause",  as
          defined in Paragraph 6(d)(ii) below.  Employee's entitlement  to  any
          severance pay is dependent on his execution of a complete release  of
          claims against Company and its affiliates.

          (ii)  In the event that severance pay is due to Employee as a  result
          of  the  "involuntary termination" of his employment "without cause",
          Employee will be paid six months' "base salary" at the rate in effect
          immediately   prior   to  the  termination  in  six   equal   monthly
          installments  (subject to all applicable taxes and other deductions),
          with  the first such installment due 15 days after the date  of  such
          termination  and with the following five installments  due  no  later
          than monthly thereafter on Company's then regular payroll dates.  The
          Company  will  also pay the employer contribution and  administrative
          cost  of  the health and accident insurance premiums for the  medical
          insurance coverage previously maintained by the Company for  Employee
          during this six month period or until Employee is provided or obtains
          medical  insurance coverage by another employer or entity,  whichever
          first   occurs.    Company  will  continue  to   make   the   pension
          contributions provided under Section 5(a) with respect  to  severance
          payments during the severance pay period but shall otherwise have  no
          obligation  to  continue any benefits other than  salary  during  the
          severance pay period.

          (iii)      Any  severance  payment due  as  a  result  of  Employee's
          termination  of his employment as provided in Section 6(a)(ii)  above
          shall be reduced by any compensation granted to Employee by the Swiss
          courts,  if  any,  with  such  reduction  to  apply  to  the   latest
          installments otherwise due.

     (c)  Change of Control - Separation Benefits.

          (i)   Upon  "involuntary  termination" of his  employment  due  to  a
          "change  of control" of Heska Corporation, Employee will be  entitled
          to  severance pay as provided in Paragraph 6(c)(iv) below, unless  he
          is  terminated  for "cause", as defined in Paragraph 6(d)(ii)  below.
          Employee's  entitlement  to any severance pay  is  dependent  on  his
          execution  of  a complete release of claims against Company  and  its
          affiliates.

          (ii)  For  the  purposes  of this Employment  Agreement,  "change  of
          control" is defined as the merger, acquisition or sale of Company  or
          all or substantially all of its assets with, into, or to a previously
          unaffiliated  third party entity, other than a merger  in  which  the
          shareholders  of  Company  prior to the merger,  by  reason  of  such
          shareholdings,  own more than 50% of the outstanding  shares  of  the
          company after the merger.

          (iii)      The parties agree that for the purposes of this Employment
          Agreement, an "involuntary termination" due to a "change of  control"
          will  be  deemed to have occurred when Employee is no longer employed
          by  the  Company's successor following a "change of control"  because
          the  Employee's position is eliminated within nine (9) months of  the
          "change  of  control"  or  when Employee's job  responsibilities  are
          materially  and  negatively changed within nine  (9)  months  of  the
          "change  of  control",  and Employee elects  to  resign,  or  if  new
          position  requires Employee to commute more than 50km each  way  from
          present home and Employee elects to resign.

          (iv)  In the event that severance pay is due to Employee as a  result
          of  the  "involuntary termination" of his employment without  "cause"
          due  to  a "change of control", Employee will be paid one (1)  year's
          "base  salary"  at  the  rate  in effect  immediately  prior  to  the
          termination  in  twelve equal monthly installments  (subject  to  all
          applicable   taxes  and  other  deductions),  with  the  first   such
          installment due 15 days after the date of such termination  and  with
          the   following  eleven  installments  due  no  later  than   monthly
          thereafter on Company's then regular payroll dates.  The Company will
          also  pay  the employer contribution and administrative cost  of  the
          health  and  accident  insurance premiums for the  medical  insurance
          coverage  previously  maintained by the Company for  Employee  during
          this one year period or until Employee is provided or obtains medical
          insurance  coverage  by another employer or entity,  whichever  first
          occurs.   Company  will  continue to make the  pension  contributions
          provided under Section 5(a) with respect to severance payments during
          the severance pay period.

     (d)  Termination "For Cause"; Voluntary Resignation.

          (i)  If Company or its successor terminates Employee for "cause",  or
          if  Employee's  employment terminates for any  reason  other  than  a
          termination  as  permitted  by Paragraph 6(a)(iii),  by  the  Company
          "without cause" (as set forth in paragraph 6(b)), or due to a "change
          of  control" (as set forth in Paragraph 6(c)), Employee will  not  be
          entitled  to  any  severance  pay and  shall  only  receive  pay  and
          benefits, as prescribed by Swiss law according to paragraph 6(a)(i).

          (ii)  The  parties  agree that for the purposes  of  this  Employment
          Agreement, a termination for "cause" will be deemed to have  occurred
          when   Company  terminates  Employee's  employment  because  of   the
          occurrence of any of the following events:

               (A)   Employee  shall  refuse to accept a reasonable  change  or
               modification of his title, duties or responsibilities by  senior
               management and/or the Board of Directors;

               (B)   Employee shall refuse to accept a reasonable transfer  not
               arising  from a change in control to a position with  comparable
               responsibility and salary with any affiliated company that  does
               not involve commuting more than 50km's each way from his present
               home;

               (C)    Employee  shall  die,  be  adjudicated  to  be   mentally
               incompetent or become mentally or physically disabled to such an
               extent that Employee is unable to perform his duties under  this
               Employment  Agreement  for a period of ninety  (90)  consecutive
               days;

               (D)   Employee shall commit any breach of his obligations  under
               this Agreement;

               (E)   Employee shall commit any breach of any material fiduciary
               duty to Company;

               (F)   Employee  shall be convicted of, or enter a plea  of  nolo
               contendere   to,   any  crime  involving  moral   turpitude   or
               dishonesty, whether a felony or misdemeanor, or any crime  which
               reflects  so  negatively  on Company as  to  be  detrimental  to
               Company's image or interests;

               (G)   Employee shall commit insubordination or refusal to comply
               with any request of his supervisor or the Board of Directors  of
               Company  relating  to  the  scope or performance  of  Employee's
               duties;

               (H)  Employee shall possess any illegal drug on Company premises
               or  Employee  shall be under the influence of illegal  drugs  or
               abusing  prescription drugs or alcohol while on Company business
               or on Company premises; or

               (I)   Employee  shall conduct himself in a manner that,  in  the
               good faith and reasonable determination of the Senior Management
               and/or the Board of Directors, demonstrates Employee's unfitness
               to serve.

7.   Proprietary Information.  Employee agrees that, if he has not already done
so,   he   will   promptly  execute  Company's  standard  employee  proprietary
information and assignment of inventions agreement.

8.    Arbitration; Attorneys' Fees.  If any dispute arises under this Agreement
or  by  reason  of  any asserted breach of it, or from the Parties'  employment
relationship  or  any other relationship, the Company, at its sole  discretion,
may  elect to have the dispute resolved through arbitration, so long as all  of
the  arbitrator's fees and expenses are borne exclusively by the Company.   The
arbitration  shall be conducted pursuant to the rules of the  applicable  Swiss
Arbitration body, with the arbitrator being selected by mutual agreement of the
parties.  Regardless of whether the dispute is resolved through arbitration  or
litigation,  the prevailing party shall be entitled to recover  all  costs  and
expenses,  including  reasonable  attorneys' fees,  incurred  in  enforcing  or
attempting  to  enforce  any of the terms, covenants or  conditions,  including
costs  incurred prior to commencement of arbitration or legal action,  and  all
costs  and  expenses,  including reasonable attorneys' fees,  incurred  in  any
appeal  from  an  action  brought to enforce any of  the  terms,  covenants  or
conditions.  For purposes of this section, "prevailing party" includes, without
limitation, a party who agrees to dismiss a suit or proceeding upon the other's
payment or performance of substantially the relief sought.

9.    Notices.   Any  notice to be given to Company under  the  terms  of  this
Agreement  shall be addressed to Company at the address of its principal  place
of  business.  Any notice to be given to Employee shall be addressed to him  at
his home address last shown on the records of Company, or to such other address
as Employee shall have given notice of hereunder.

10.   Miscellaneous.   This Agreement shall be governed  by  Swiss  law.   This
Agreement  is the entire agreement of the parties with respect to  the  subject
matter  hereof  and supersedes all prior understandings and  agreements.   This
Agreement  may  be modified only by a written document signed by both  parties,
except that the Company, in its discretion, may modify any policies, guidelines
or  other  directives,  none of which shall constitute a binding  agreement  or
impose  any contractual obligations.  This Agreement shall be binding upon  and
shall inure to the benefit of the successors and assigns of the parties.

IN WITNESS WHEREOF, the parties hereto have executed this Agreement the day and
year hereinabove written.
