         The  undersigned,  PLC Systems  Inc., a British  Columbia  corporation,
which together with its wholly-owned  subsidiary,  PLC Medical Systems,  Inc., a
Delaware  corporation,  as  well  as its  successors  and  assigns  (hereinafter
collectively referred to as the "Company"), hereby agree with you as follows:

         l.       Employment Following Change in Control.

                  1.1 Your  employment with the Company may be terminated at any
time,  except that in the event of a "Change of Control" as defined herein,  you
will have the right to the payments described herein.

                  1.2 For purposes of this  Agreement,  the term  "Cause"  shall
mean (a) gross negligence in the performance of assigned duties;  (b) refusal to
perform or  discharge  the duties or  responsibilities  assigned by the Board of
Directors of PLC Systems Inc. or PLC Medical Systems, Inc. provided the same are
not illegal,  unethical  or  inconsistent  with the position of Chief  Financial
Officer of a  corporation  and the failure to correct  such  refusal and perform
such  duties or  responsibilities  within  two weeks (14  calendar  days)  after
written  notice of such  failure;  (c)  conviction of a felony  involving  moral
turpitude; (d) willful or prolonged absence from work not excused by disability;
and (e) falseness of any warranty or  representation by you herein or the breach
of your  obligations  under this  Agreement  to the  material  detriment  of the
Company.

                  1.3 In  the  event  of the  Involuntary  Termination  of  your
employment  with the Company  during the  one-year  period,  the Company  hereby
agrees to make  payments to you as described  in Section 2. In this regard,  the
phrase  "Involuntary  Termination" shall mean any termination of your employment
by the  Company  other than for  "Cause"  following  a "Change of  Control,"  as
defined in Section 2, or any termination of your employment  following a "Change
in Control"  by you  following a "Change in Control" as defined in Section 2 due
to any of the  following  circumstances:  (a) a reduction in your Base Salary or
Company-paid benefits, (b) a reduction in your eligibility for any Company bonus
or other benefit  program,  (c) a material or substantial  change in your title,
position,  authority  or  duties,  or (d) a change  of your  principal  place of
employment from Milford,  Massachusetts  to another  location beyond 25 miles of
Milford, Massachusetts.

                  1.4 At any time  prior to a Change in  Control,  upon not less
than seven (7) calendar days written  notice,  your  employment with the Company
may be terminated without

                                       -1-





"Cause",  provided  that the Company shall be obligated to pay you, as severance
pay,  an amount  equal to twelve (12)  months of your then  current  annual base
salary  plus any sums  then due to you,  less (i)  applicable  taxes  and  other
required withholdings,  and (ii) any amount you may owe to the Company.  Subject
to Section 2, payments under this Section 1.4 shall not be due or payable if you
are  terminated at any time for "Cause" or if you  voluntarily  resign from your
employment.  It is also understood and agreed that the severance  amount will be
paid to you in accordance with the standard Company payroll  procedures and that
should you obtain  employment  from  another  source prior to the receipt of the
entire severance amount, the unpaid amount shall be forfeited by you.

         2.       Change in Control.

         (a) For purposes of this Agreement, "Change in Control" means and shall
be deemed to occur if any of the following occurs:

                  (i)  The   acquisition,   after  September  30,  1994,  by  an
         individual,  entity or group [within the meaning of Section 13(d)(3) or
         14(d)(2)  of the  Securities  Exchange  Act of  1934  as  amended  (the
         "Exchange  Act")] of beneficial  ownership  (within the meaning of Rule
         13d-3  promulgated under the Exchange Act) of 25% or more of either (A)
         the outstanding  shares of common stock, no par value per share, of the
         Company (the "Common  Stock"),  or (B) the combined voting power of the
         voting  securities  of the Company  entitled to vote  generally  in the
         election of directors (the "Voting  Securities");  or (ii)  Individuals
         who, on September 30, 1994,  constituted  the Board of Directors of the
         Company (the  "Incumbent  Board") cease for any reason to constitute at
         least a majority of the Board of Directors  of the  Company;  provided,
         however,   that  any  individual  becoming  a  director  subsequent  to
         September 30, 1994 whose  election,  or nomination  for election by the
         Company's  shareholders,  was approved by a vote of at least a majority
         of the directors then serving and comprising the Incumbent  Board shall
         be considered as though such  individual were a member of the Incumbent
         Board,  but  excluding,  for this purpose,  any such  individual  whose
         initial  assumption of office occurs as a result of either an actual or
         threatened  election  contest (as such terms are used in Rule 14a-11 of
         Regulation 14A  promulgated  under the Exchange Act) or other actual or
         threatened  solicitation  of proxies or consents;  or (iii) Approval by
         the Board of  Directors  or the  shareholders  of the  Company of a (A)
         tender offer to acquire any of the Common  Stock or Voting  Securities,
         (B)  reorganization,  (C)  merger or (D)  consolidation,  other  than a
         reorganization,  merger or  consolidation  with respect to which all or
         substantially  all  of  the  individuals  and  entities  who  were  the
         beneficial owners, immediately prior to such reorganization,  merger or
         consolidation,  of the Common Stock and Voting Securities  beneficially
         own,  directly or indirectly,  immediately  after such  reorganization,
         merger or consolidation,  more than 80% of the then outstanding  common
         stock and Voting Securities (entitled to vote generally in the election
         of directors) of the Company resulting from such reorganization, merger
         or  consolidation  in  substantially  the  same  proportions  as  their
         respective ownership, immediately prior to such reorganization,

                                       -2-





         merger or consolidation, of the Common Stock and the Voting Securities;
         or (iv) Approval by the Board of Directors or the  shareholders  of the
         Company of (A) a complete or substantial  liquidation or dissolution of
         the  Company,   or  (B)  the  sale  or  other  disposition  of  all  or
         substantially   all  of  the  assets  of  the   Company,   excluding  a
         reorganization  of the Corporation  under the corporate laws of a state
         or province other than British Columbia.

         (b)  In  the   event  of  your   actual   termination   of   employment
contemporaneous  with or  during  the  one-year  period  following  a Change  in
Control,  except (x)  because of your  death,  (y) by the  Company  for Cause or
Disability (as hereinafter defined) or (z) by you other than for Good Reason (as
hereinafter  defined):  (i) you shall be entitled to receive an amount  equal to
100% of your current fiscal year's total compensation (base salary, benefits and
any bonuses paid to you during the  preceding  twelve (12) months) to be paid in
accordance with the terms of this Agreement;  and (ii) the following  additional
provisions shall apply (which provisions shall supersede any other provisions of
the Agreement,  including but not limited to Section 1 of the Agreement,  to the
extent such provisions are inconsistent with the following provisions):

                  (1) Disability. For purposes of this Section 2(b), termination
by the Company of your employment  based on "Disability"  shall mean termination
because of your absence from your duties with the Company for one hundred eighty
(180)  consecutive  days as a result of your incapacity and inability to perform
the essential functions of your position with reasonable  accommodation,  unless
within thirty (30) days after Notice of Termination (as hereinafter  defined) is
given to you following such absence,  you shall have returned to the performance
of the essential functions of your position with reasonable accommodation.

                  (2) Cause.  For purposes of this Section 2, termination by the
Company of your  employment  for "Cause" shall mean  termination  for "Cause" as
defined in Section 1.2.


                  (3) Good Reason.  Termination  by you of your  employment  for
"Good Reason" shall mean termination based on:

                           (A)  a  determination  by  you,  in  your  reasonable
judgment,  that  there has been a  material  adverse  change  in your  status or
position(s)  as an  executive  officer of the  Company as in effect  immediately
prior to the  Change in  Control,  including,  without  limitation,  a  material
adverse  change in your status or position as a result of a  diminution  in your
duties or responsibilities (other than, if applicable,  any such change directly
attributable  to the fact that the Company is no longer  publicly  owned) or the
assignment to you of any duties or responsibilities  which are inconsistent with
such  status or  position(s),  or any  removal  of you from,  or any  failure to
reappoint or reelect you to, such  position(s)  (except in  connection  with the
termination  of your  employment  for Cause or Disability or as a result of your
death or by you other than for Good Reason);

                           (B) a reduction by the Company in your Base Salary as
in effect immediately prior to the Change in Control;


                                       -3-


                           (C) the  failure by the Company to continue in effect
any Plan (as hereinafter  defined) in which you are participating at the time of
the Change in  Control  of the  Company  (or Plans  providing  you with at least
substantially  similar benefits) other than as a result of the normal expiration
of any such  Plan in  accordance  with its terms as in effect at the time of the
Change in Control,  or the taking of any  action,  or the failure to act, by the
Company which would adversely affect your continued participation in any of such
Plans on at least as  favorable a basis to you as is the case on the date of the
Change in Control or which would  materially  reduce your benefits in the future
under any of such Plans or deprive you of any material benefit enjoyed by you at
the time of the Change in Control;

                           (D) the  failure by the Company to provide and credit
you with the  number of paid  vacation  days to which you are then  entitled  in
accordance with the Company's  normal  vacation policy as in effect  immediately
prior to the Change in Control;

                           (E) the  Company's  requiring  you to be based at any
office that is greater than twenty-five  miles from where your office is located
immediately  prior to the Change in Control  except for  required  travel on the
Company's  business  to an extent  substantially  consistent  with the  business
travel  obligations  which you  undertook on behalf of the Company  prior to the
Change in Control;

                           (F) the  failure by the  Company  to obtain  from any
Successor (as hereinafter defined) the assent to this Agreement  contemplated by
Section 2(b)(7) hereof;

                           (G) any purported  termination by the Company of your
employment which is not effected pursuant to a Notice of Termination  satisfying
the  requirements of Section 2(b)(4) below (and, if applicable,  Section 2(b)(2)
above); and for purposes of this Agreement,  no such purported termination shall
be effective; or

                           (H) any  refusal by the  Company to continue to allow
you to attend to matters or engage in  activities  not  directly  related to the
business  of the  Company  which,  prior  to the  Change  in  Control,  you were
permitted by the Board to attend to or engage in.

         For purposes of this Agreement, "Plan" shall mean any compensation plan
or any employee benefit plan such as a thrift, pension, profit sharing, medical,
disability,  accident, life insurance plan or a relocation plan or policy or any
other plan, program or policy of the Company intended to benefit employees.

                  (4) Notice of  Termination.  Any purported  termination by the
Company or by you following a Change in Control shall be communicated by written
notice to the other  party  hereto  which  indicates  the  specific  termination
provision in this Agreement relied upon (the "Notice of Termination").


                                       -4-


                  (5) Date of  Termination.  "Date of  Termination"  following a
Change in Control  shall mean (A) if your  employment  is to be  terminated  for
Disability, thirty (30) days after Notice of Termination is given (provided that
you shall not have returned to the  performance  of the  essential  functions of
your position with reasonable accommodation during such thirty (30) day period),
(B) if your  employment  is to be terminated by the Company for any reason other
than death or  Disability  or by you pursuant to Sections  2(b)(3)(F) or 2(b)(7)
hereof  or for any  other  Good  Reason,  the date  specified  in the  Notice of
Termination,  or (C) if your  employment is terminated on account of your death,
the day after your death.  In the case of termination of your  employment by the
Company  for  Cause  pursuant  to  Subsection  2(b)(2)  hereof,  if you have not
previously  expressly agreed in writing to the  termination,  then within thirty
(30) days  after  receipt  by you of the  Notice  of  Termination  with  respect
thereto,  you may  notify  the  Company  that a dispute  exists  concerning  the
Termination, in which event the Date of Termination shall be the date set either
by mutual  written  agreement  of the parties or by such court having the matter
before it. During the pendency of any such dispute, the Company will continue to
pay you your full  compensation  in effect  just prior to the time the Notice of
Termination is given and until the dispute is resolved.  However,  if such court
issues a final and  non-appealable  order  finding that the Company had Cause to
terminate you, then you must return all compensation  paid to you after the Date
of  Termination  specified in the Notice of Termination  previously  received by
you.

    (6) Compensation Upon Termination or During Disability; Other Agreements.

                  (A)  During any  period  following  a Change in Control of the
Company  that you fail to perform your duties as a result of  incapacity  due to
physical or mental  illness,  you shall  continue to receive your Base Salary at
the rate then in effect and any benefits or awards under any Plan shall continue
to accrue during such period,  to the extent not  inconsistent  with such Plans,
until and unless your  employment  is  terminated  pursuant to and in accordance
with this  Section  2(b).  Thereafter,  your  benefits  shall be  determined  in
accordance with the Plans then in effect.

                  (B) If your  employment  is terminated  for Cause  following a
Change in Control of the Company,  the Company shall pay to you your Base Salary
through the Date of  Termination  at the rate in effect just prior to the time a
Notice of Termination is given plus any benefits or awards  (including  both the
cash and stock  components)  which  pursuant to the terms of any Plans have been
earned or become payable, but which have not yet been paid to you. Thereupon the
Company shall have no further obligations to you under this Agreement.

                  (7)      Successors, Binding Agreement.

                  (A) The Company  will seek,  by written  request at least five
(5) business days prior to the time a Person becomes a Successor (as hereinafter
defined),  to have such Person, by agreement in form and substance  satisfactory
to you,  assent to the  fulfillment  of the  Company's  obligations  under  this
Agreement.  Failure of such  Person to furnish  such  assent by the later of (i)
three (3)  business  days prior to the time such Person  becomes a Successor  or
(ii) two (2) business  days after such Person  receives a written  request to so
assent shall constitute Good Reason for termination by

                                       -5-


you of your  employment  if a Change in  Control  of the  Company  occurs or has
occurred. For purposes of this Agreement, "Successor" shall mean any person that
succeeds to, or has the practical ability to control (either immediately or with
the  passage  of  time),  the  Company's   business   directly,   by  merger  or
consolidation,  or indirectly,  by purchase of the Company's securities eligible
to vote for the election of directors, or otherwise.

                  (B)  This  Agreement  shall  inure  to the  benefit  of and be
enforceable by your personal legal representatives,  executors,  administrators,
successors, heirs, distributees,  devisees and legatees. If you should die while
any amount would still be payable to you hereunder if you had continued to live,
all such amounts,  unless otherwise provided herein, shall be paid in accordance
with the terms of this Agreement to your devisee,  legatee or other designee or,
if no such designee exists, to your estate.

                  (C) For  purposes  of this  Section  2,  the  "Company"  shall
include any  subsidiaries  of the Company and any  corporation  or other  entity
which  is  the  surviving  or  continuing  entity  in  respect  of  any  merger,
consolidation  or form of business  combination  in which the Company  ceases to
exist;  provided,  however,  for  purposes  of  determining  whether a Change in
Control has occurred herein,  the term "Company" shall refer to PLC Systems Inc.
or its Successor(s).

                  (8)      Fees and Expenses; Mitigation.

                           (A) The  Company  shall  reimburse  you, on a current
basis,  for all reasonable  legal fees and related  expenses  incurred by you in
connection  with the  Agreement  following  a Change in Control of the  Company,
including without limitation,  (i) all such fees and expenses,  if any, incurred
in  contesting  or disputing  any  termination  of your  employment or (ii) your
seeking to obtain or enforce any right or benefit provided by this Agreement, in
each  case,  regardless  of  whether  or not your  claim is upheld by a court of
competent  jurisdiction;  provided,  however, you shall be required to repay any
such  amounts  to the  Company  to the  extent  that a court  issues a final and
non-appealable  order setting forth the determination that the position taken by
you was frivolous or advanced by you in bad faith.

                           (B) You shall not be required to mitigate  the amount
of any payment the Company  becomes  obligated to make to you in connection with
this Agreement, by seeking other employment or otherwise.

                  (9) Taxes. All payments to be made to you under this Agreement
will be subject to required  withholding of federal,  state and local income and
employment taxes.

         (d) Notwithstanding any other provision of this Agreement, in the event
that any payment of benefit  received or to be received by you as a result of or
in connection  with a Change in Control,  whether  pursuant to the terms of this
Agreement or any other plan, arrangement or agreement with the Company (all such
payment  and  benefits  being  hereinafter  called the "Total  Payments")  would
subject you to the excise tax (the "Excise  Tax")  imposed under Section 4999 of
the Internal Revenue

                                       -6-



Code of 1986,  as  amended  (the  "Code"),  then,  to the  extent  necessary  to
eliminate  any such  imposition of the Excise Tax (after taking into account any
reduction in the Total  Payments in accordance  with the provisions of any other
plan,  arrangement or agreement,  if any), (a) any non-cash  severance  payments
otherwise payable to you shall first be reduced (if necessary, to zero), and (b)
any cash severance payment  otherwise payable to you shall next be reduced.  For
purposes  of the  immediately  preceding  sentence,  (i) no portion of the Total
Payments, the receipt or enjoyment of which you shall have effectively waived in
writing, shall be taken into account, (ii) no portion of the Total Payment shall
be taken into account which in the opinion of nationally-recognized  tax counsel
or  certified  public  accountants  (in each case as  selected  by you) does not
constitute a "parachute payment" within the meaning of Section 280G of the Code,
including,  without limitation,  by reason of Section 280G(b)(2) or (b)(4)(A) of
the  Code,  (iii)  any  payments  to you  shall be  reduced  only to the  extent
necessary so that the Total  Payments  [other than those  referred to in clauses
(i) and (ii)] in their entirety constitute reasonable  compensation for services
actually  rendered  within the meaning of section  280G(4)(B) of the Code or are
otherwise not subject to disallowance  as deductions,  in the opinion of the tax
counsel or the accountants referred to in clause (ii); and (iv) the value of any
non-cash  benefit  or any  deferred  payment or  benefit  included  in the Total
Payments  shall  be  determined  by such  accountants  in  accordance  with  the
requirements of section  280G(d)(3) and (4) of the Code (and such  determination
shall be reviewed by such tax counsel).

         3.       Post-Employment Activities.

                  3.1 For a period  of one (1) year  after  the  termination  or
expiration,  for any reason,  of your  employment  with the  Company  hereunder,
absent the Company's prior written approval, you will not directly or indirectly
engage in activities  similar or reasonably  related to those in which you shall
have engaged hereunder during the two years immediately preceding termination or
expiration for, nor render services similar or reasonably related to those which
you shall have rendered hereunder during such two years to, any person or entity
whether now existing or hereafter  established  which directly competes with (or
proposes or plans to directly compete with) the Company ("Direct Competitor") in
any line of business engaged in or under  development by the Company.  Nor shall
you entice,  induce or encourage any of the Company's  other employees to engage
in any activity which,  were it done by you, would violate any provision of this
Section 3. As used in this Section  3.1, the term "any line of business  engaged
in or under  development  by the  Company"  shall be  applied  as at the date of
termination of your  employment,  or, if later, as at the date of termination of
any post-employment consultation.

                  3.2 For a period of one (1) year after the termination of your
employment  with the Company,  the provisions of Section 3.1 shall be applicable
to you and you  shall  comply  there  with.  As  applied  to such  one (1)  year
post-employment period, the term "any other line of business engaged in or under
development  by the Company," as used in Section 3.1, shall be applied as at the
date of termination of your  employment with the Company or, if later, as at the
date of termination of any post-employment consultation with the Company.


                                       -7-


                  3.3 No  provision  of this  Agreement  shall be  construed  to
preclude you from  performing the same services which the Company hereby retains
you to perform for any person or entity which is not a Direct  Competitor of the
Company  upon  the  expiration  or  termination  of  your   employment  (or  any
post-employment  consultation) so long as you do not thereby violate any term of
the Proprietary Information and Inventions Agreement.

         4. Remedies. Your obligations under the provisions of Section 3 of this
Agreement (as modified by Section 6, if applicable) shall survive the expiration
or  termination  of  your  employment   (whether  through  your  resignation  or
otherwise) with the Company. You acknowledge that a remedy at law for any breach
or threatened  breach by you of the  provisions of Section 3 would be inadequate
and you therefore  agree that the Company  shall be entitled to such  injunctive
relief in case of any such breach or threatened breach.

         5.  Assignment.  This  Agreement and the rights and  obligations of the
parties  hereto  shall  bind  and  inure  to the  benefit  of any  successor  or
successors of the Company by  reorganization,  merger or  consolidation  and any
assignee of all or substantially all of its business and properties, but, except
as to any such successor or assignee of the Company,  neither this Agreement nor
any rights or  benefits  hereunder  may be  assigned  by the  Company or by you,
except by operation of law.

         6. Interpretation. IT IS THE INTENT OF THE PARTIES THAT in case any one
or more of the provisions  contained in this Agreement shall, for any reason, be
held to be invalid,  illegal or unenforceable  in any respect,  such invalidity,
illegality  or  unenforceability  shall not affect the other  provisions of this
Agreement,  and this Agreement shall be construed as if such invalid, illegal or
unenforceable  provision had never been contained  herein.  MOREOVER,  IT IS THE
INTENT OF THE PARTIES  THAT if any one or more of the  provisions  contained  in
this Agreement is or becomes or is deemed invalid,  illegal or  unenforceable or
in case any provision shall for any reason be held to be excessively broad as to
duration,  geographical  scope,  activity or subject,  such  provision  shall be
construed by amending, limiting and/or reducing it to conform to applicable laws
so as to be valid  and  enforceable  or,  if it  cannot  be so  amended  without
materially  altering the intention of the parties,  it shall be stricken and the
remainder of this Agreement shall remain in full force and effect.

         7.  Notices.  Any notice which the Company is required to or may desire
to give you shall be given by personal delivery or registered or certified mail,
return  receipt  requested,  addressed to you at your address of record with the
Company,  or at such  other  place as you may  from  time to time  designate  in
writing.  Any notice which you are required or may desire to give to the Company
hereunder  shall be given by personal  delivery or by  registered  or  certified
mail,  return  receipt  requested,  addressed  to the  Company at its  principal
office,  or at such other office as the Company may from time to time  designate
