life  insurance  plans,  accident  and  health  plans and other  welfare  plans,
maintained or sponsored by the Company immediately prior to the termination,  at
the same level and subject to terms at least as  favorable  to  Executive  as in

the Company, until the earlier of (a) the Executive's eligibility for comparable
benefit  plans  with  another   employer  and  (b)  the  third   anniversary  of

         responsibilities  as  contemplated  by  Section  2.1 above or any other

         offices,  or any event  that  causes  Executive  to have his  principal
         location of work changed, to any location outside the Area;

                  (vii) any  requirement  by the Company that  Executive  travel
         away from his  office in the course of his  duties  significantly  more
         than the number of  consecutive  days or aggregate days in any calendar
         year than was required of him prior to the Change in Control; or

                  (viii)  without  limiting  the  generality  or  effect  of the
         foregoing any material  breach of this  Agreement by the Company or any
         successor  thereto or  transferee  of  substantially  all of the assets

agrees that,  if requested by the Company,  he will remain as an employee of the
Company during the Transition Period.  During the Transition Period, the Company
will continue to pay the Executive the Executive's base salary, annual bonus and
all other compensation and benefits on the same basis as such items were paid to
the Executive prior to his resignation.

         4.4. Resignation by Executive.  If Executive resigns during the Term of
Employment  without Good Reason,  the Executive  shall have the right to receive
base salary,  annual bonuses,  contributions  to Retirement  Plans and all other
compensation  and benefits earned during the calendar year of his resignation up
to the date of his resignation.  For purposes of this Section 4.4, the amount of
the annual bonuses and the amount of the  contributions  to the Retirement  Plan
shall be at least equal to the amounts paid to, or contributed on behalf of, the
Executive for the year  immediately  preceding the year in which the resignation
of the Executive  occurs which amounts shall be prorated  based on the number of
days in the year in which such resignation occurs which have passed prior to the
date of such  resignation.  In addition all vested  Non-Qualified  Plan benefits
shall be paid within thirty (30) days of resignation.

         4.5.  Termination  for Cause.  If Executive is dismissed by the Company
for Cause,  he will not be entitled to the payments or benefits  provided  under
Section 4.2 hereof.

         4.6.  Dispute  Resolution.  All  disputes  between  the parties to this
Agreement  concerning the matters set forth herein shall be resolved exclusively
pursuant  to  the  dispute  resolution   procedures  of  this  Section  4.6.  In
furtherance  thereof,  Executive  or the  Company,  as the  case  may be,  shall
initiate  binding  arbitration  in Rhode Island before the American  Arbitration
Association  ("AAA") and under its rules by serving a notice to  arbitrate  upon
the other party hereto and AAA within 90 days of the  occurrence  of any dispute
hereunder that is unable to be resolved by negotiation between the parties.  The
parties shall bear their respective costs in any such dispute resolution, except
that with respect to any such action  initiated by the  Executive,  provided the
Executive initiates such action in good faith, the Company agrees (i) to pay the
costs and  expenses  (including  fees of counsel to the  Executive)  of any such
arbitration or judicial proceeding, and (ii) to pay interest to Executive on any
amounts  found to be due to Executive  hereunder  during any period of time that
such amounts are withheld pending arbitration and/or judicial proceedings.  Such
interest  will be at the base or prime  rate most  recently  announced  by Rhode
Island Hospital Trust National Bank (or its successor) prior to the commencement
of the  arbitration  or  litigation.  The Company and  Executive  agree that any
arbitration award shall be binding and may be enforced by any court of competent
jurisdiction.

         4.7.     Death or Total Disability of the Executive.

         (a) If Executive dies or suffers a Total Disability  during the Term of
Employment,  then this Agreement shall terminate and the Company, its successors
and  assigns  shall  be  relieved  and  discharged  of any and  all  obligations
whatsoever  to make further  payment to Executive  pursuant to the terms of this
Agreement after the date of death or Total Disability of Executive, except as to
base salary earned for services actually rendered and vacation pay accrued prior
to the date of death or Total Disability of Executive.

         (b) If  Executive  dies or  suffers  a  Total  Disability  following  a
termination of employment which entitled him to payments and benefits under this
Section  4 but  prior  to  receipt  of  all  such  payments  and  benefits,  his
beneficiary  (as  designated to the Company in writing) or, if none, his estate,
will be  entitled  to receive all unpaid  amounts  and  benefits  due under this
Agreement.

         4.8.  Enforcement of Rights.  Termination  of  Executive's  employment,
whether or not giving rise to payments  or benefits  under this  Section 4, will
not in any way prevent  Executive from enforcing  rights to payments or benefits
under Section 3 relating to periods during which he was employed.

         Section 5.  Certain Additional Payments by the Company.

         (a)  Anything in this  Agreement to the  contrary  notwithstanding  and
except as set forth below,  in the event it shall be determined that any payment
or distribution  by the Company to or for the benefit of the Executive  (whether
paid or payable or  distributed or  distributable  pursuant to the terms of this
Agreement or otherwise, but determined without regard to any additional payments
required under this Section 5) (a "Payment")  would be subject to the excise tax
imposed by Section 4999 of the Code or any interest or penalties are incurred by
the  Executive  with respect to such excise tax (such excise tax,  together with
any such interest and penalties, are hereinafter collectively referred to as the
"Excise  Tax"),  then the  Executive  shall be entitled to receive an additional
payment (a  "Gross-Up  Payment")  in an amount  such that  after  payment by the
Executive of all taxes (including any interest or penalties imposed with respect
to such  taxes),  including,  without  limitation,  any  income  taxes  (and any
interest and penalties imposed with respect thereto) and Excise Tax imposed upon
the Gross-Up  Payment,  the Executive  retains an amount of the Gross-Up Payment
equal to the Excise Tax imposed on the Payments.

         (b)  Subject to the  provisions  of Section  5(c),  all  determinations
  required  to be made  under  this  Section  5,  including  whether  and when a
  Gross-Up  Payment is required and the amount of such Gross-Up  Payment and the
  assumptions to be utilized in arriving at such determination, shall be made by
  Ernst &  Young  LLP or  such  other  nationally  recognized  certified  public
  accounting firm as may be designated by the Executive (the "Accounting  Firm")
  which shall provide detailed  supporting  calculations both to the Company and
  the  Executive  within 15  business  days of the  receipt  of notice  from the
  Executive that there has been a Payment,  or such earlier time as is requested
  by the Company. In the event that the Accounting Firm is serving as accountant
  or  auditor  for the  individual,  entity  or group  effecting  the  Change in
  Control, the Executive shall appoint another nationally  recognized accounting
  firm to make the  determinations  required  hereunder  (which  accounting firm
  shall then be  referred to as the  Accounting  Firm  hereunder).  All fees and
  expenses of the  Accounting  Firm shall be borne  solely by the  Company.  Any
  Gross-Up Payment,  as determined  pursuant to this Section 5, shall be paid by
  the Company to the Executive within five days of the receipt of the Accounting
  Firm's  determination.  Any  determination  by the  Accounting  Firm  shall be
  binding upon the Company and the Executive.  As a result of the uncertainty in
  the  application  of Section  280G and Section 4999 of the Code at the time of
  the initial  determination  by the Accounting Firm  hereunder,  it is possible
  that  Gross-Up  Payments  which will not have been made by the Company  should
  have been made ("Underpayment"),  consistent with the calculations required to
  be made  hereunder.  In the  event  that the  Company  exhausts  its  remedies
  pursuant to Section 5(c) and the  Executive  thereafter  is required to make a
  payment of any Excise Tax, the Accounting  Firm shall  determine the amount of
  the Underpayment that has occurred and any such Underpayment shall be promptly
  paid by the Company to or for the benefit of the Executive.

         (c) The  Executive  shall notify the Company in writing of any claim by
the Internal  Revenue Service that, if successful,  would require the payment by
the Company of the Gross-Up Payment. Such notification shall be given as soon as
practicable  but no later than ten business days after the Executive is informed
in  writing of such claim and shall  apprise  the  Company of the nature of such
claim and the date on which such claim is  requested to be paid.  The  Executive
shall not pay such claim prior to the expiration of the 30-day period  following
the date on which he gives such notice to the Company  (or such  shorter  period
ending on the date that any payment of taxes with respect to such claim is due).
If the Company notifies the Executive in writing prior to the expiration of such
period that it desires to contest such claim, the Executive shall:

                  (i)      give the Company any information
         reasonably requested by the Company relating to such claim,

                  (ii) take such action in connection with contesting such claim
         as the Company shall  reasonably  request in writing from time to time,
         including,  without  limitation,  accepting legal  representation  with
         respect  to  such  claim  by an  attorney  reasonably  selected  by the
         Company,

                  (iii)  cooperate  with  the  Company  in good  faith  in order
         effectively to contest such claim, and

                  (iv)     permit the Company to participate in any
         proceedings relating to such claim;

provided,  however,  that the Company  shall bear and pay directly all costs and
expenses  (including  additional  interest and penalties) incurred in connection
with such contest and shall  indemnify  and hold the Executive  harmless,  on an
after-tax  basis,  for any  Excise  Tax or income tax  (including  interest  and
penalties with respect thereto) imposed as a result of such  representation  and
payment of costs and expenses. Without limitation on the foregoing provisions of
this Section 5(c), the Company shall control all proceedings taken in connection
with such  contest  and,  at its sole  option,  may  pursue or forgo any and all
administrative  appeals,  proceedings,  hearings and conferences with the taxing
authority  in respect of such claim and may, at its sole option,  either  direct
the  Executive  to pay the tax claimed and sue for a refund or contest the claim
in any permissible manner, and the Executive agrees to prosecute such contest to
a  determination  before  any  administrative  tribunal,  in a court of  initial
jurisdiction  and  in  one or  more  appellate  courts,  as  the  Company  shall
determine;  provided,  however, that if the Company directs the Executive to pay
such claim and sue for a refund,  the Company  shall  advance the amount of such
payment to the Executive, on an interest-free basis and shall indemnify and hold
the Executive harmless, on an after-tax basis, from any Excise Tax or income tax
(including  interest or penalties with respect  thereto) imposed with respect to
such advance or with respect to any imputed income with respect to such advance;
and further  provided that any extension of the statute of limitations  relating
to payment of taxes for the taxable year of the Executive  with respect to which
such  contested  amount is claimed to be due is limited solely to such contested
amount.  Furthermore,  the Company's  control of the contest shall be limited to
issues with respect to which a Gross-Up  Payment would be payable  hereunder and
the  Executive  shall be entitled to settle or contest,  as the case may be, any
other  issue  raised  by  the  Internal  Revenue  Service  or any  other  taxing
authority.

         (d) If, after the receipt by the Executive of an amount advanced by the
Company pursuant to Section 5(c), the Executive  becomes entitled to receive any
refund with respect to such claim, the Executive shall (subject to the Company's
complying with the requirements of Section 5(c)) promptly pay to the Company the
amount of such refund (together with any interest paid or credited thereon after
taxes applicable  thereto).  If, after the receipt by the Executive of an amount
advanced by the Company  pursuant to Section 5(c), a determination  is made that
the Executive shall not be entitled to any refund with respect to such claim and
the Company  does not notify the  Executive  in writing of its intent to contest
such  denial  of  refund  prior  to  the   expiration  of  30  days  after  such
determinative  then such advance  shall be forgiven and shall not be required to
be repaid and the amount of such advance  shall offset,  to the extent  thereof,
the amount of Gross-Up Payment required to be paid.

         Section 6.  Payment of Fees, Costs and Expenses.

         It is the intent of the Company that the  Executive  not be required to
incur the  expenses  associated  with the  enforcement  of his rights under this
Agreement by litigation or other legal action or arbitration  proceeding because
the cost and expense  thereof  would  substantially  detract  from the  benefits
intended to be extended to the Executive  hereunder.  Accordingly,  if Executive
determines  in good faith that the  Company has failed to comply with any of its
obligations under this Agreement or if the Company or any other person takes any
action to declare  this  Agreement  void or  unenforceable,  or  institutes  any
litigation or arbitration  proceeding  designed to deny, or to recover from, the
Executive the benefits  intended to be provided to the Executive under Section 6
hereof, the Company will promptly, upon request of the Executive in the event of
the likelihood of a Change in Control or upon a Change in Control,  use its best
efforts  to secure an  irrevocable  standby  letter of credit  (the  "Letter  of
Credit"), issued by Rhode Island Hospital Trust National Bank or another bank of
comparable  or  greater  size (the  "Bank")  for the  benefit  of the  Executive
providing  that the fees and expenses of counsel  selected  from time to time by
the  Executive  pursuant to this  Section 6 or in  proceedings  contemplated  by
Section  4.6  shall be  paid,  or  reimbursed  to the  Executive  if paid by the
Executive,  on a regular,  periodic basis upon  presentation by the Executive to
the Bank of a statement or  statements  prepared by such  counsel in  accordance
with its  customary  practices.  The Company  shall pay all amounts and take all
action  necessary to maintain the Letter of Credit during the Term of Employment
and for one (1) year thereafter and if,  notwithstanding  the Company's complete
discharge of such obligations,  such Letter of Credit shall be terminated or not
renewed,  the  Company  shall  use its best  efforts  to  obtain  a  replacement
irrevocable  letter of credit  drawn  upon a  commercial  bank  selected  by the
Company and reasonably acceptable to the Executive,  upon substantially the same
terms and  conditions  as  contained  in the  Letter of Credit,  or any  similar
arrangement  which,  in any case,  assures the  Executive  the  benefits of this
Agreement  without  incurring  any cost or expense for  enforcement  against the
Company or the defense thereof.

         Section 7.  Merger or Acquisition.

         7.1. Assumption of Obligations. If the Company is at any time before or
after a Change in Control merged,  consolidated or reorganized  into or with any
other  corporation or other entity  (whether or not the Company is the surviving
entity), or if substantially all of the assets of the Company are transferred to
another  corporation  or other  entity,  the entity  arising  from such  merger,
consolidation  or  reorganization,  or the  acquirer of such  assets,  shall (by
agreement in form and substance  satisfactory to Executive) expressly assume the
obligations of Company under this Agreement.

         7.2.  Executive's  Rights  to  Benefits.  In the  event of any  merger,
consolidation,  reorganization  or  sale  of  assets  described  above,  nothing
contained in this  Agreement  will detract from or otherwise  limit  Executive's
right to or privilege of  participation  in any stock option or purchase plan or
restricted  stock plan or any bonus,  profit sharing,  savings,  pension,  group
insurance,  hospitalization  or other  incentive or benefit plan or  arrangement
which may be or become  applicable to executives  of the  corporation  resulting
from such merger or consolidation  or the corporation,  acquiring such assets of
the Company.

         7.3.   References.   In  the  event  of  any   merger,   consolidation,
reorganization or transfer of assets described above,  references to the Company
in this Agreement  shall,  unless the context suggests  otherwise,  be deemed to
include the entity  resulting from such merger or  consolidation or the acquirer
of such assets of the Company.

         Section 8.  Change in Control Following Certain Circumstances.

         Notwithstanding  any provision herein to the contrary,  should a Change
in Control occur subsequent to Executive's death, Total Disability or retirement
from the Company,  the  remainder  of any  benefits  owed under the terms of any
stock  plans  or  other  non-qualified  deferred  compensation  plan,  including
interest, shall be paid in full on the date of the Change in Control.

         Section 9.  Termination of this Agreement.

         Either the Company or Executive  may, by giving 60 days written  notice
  to the other party, terminate this Agreement as of the third or any subsequent
  annual anniversary of the occurrence of a Change in Control.

         Section 10.  Withholding of Taxes.

         All payments  required to be made by the Company hereunder to Executive
or his dependents, beneficiaries or estate will be subject to the withholding on
such amounts relating to tax and/or other payroll  deductions as may be required
by law.

         Section 11.  Amendment.

         No  amendment,  change or  modification  of this  Agreement may be made
except in a writing, signed by or on behalf of both parties.

         Section 12.  Miscellaneous.

         12.1. Binding Effect. The provisions of this Agreement shall be binding
upon and shall inure to the benefit of Executive, his executors, administrators,
legal  representatives  and  assigns,  and the  Company and its  successors  and
assigns.

         12.2.  Governing Law. The validity,  interpretation  and effect of this
Agreement  shall be governed by and construed in accordance with the laws of the
State of Rhode Island.

         12.3.    Severability.  The invalidity or enforceability of any
provision of this Agreement shall not affect the validity of any other
provision.

         12.4. No Set-Off. There shall be no right of setoff or counterclaim, in
respect of any claim, debt or obligation, against any payments to Executive, his
dependents,  beneficiaries or estate provided for in this Agreement, and nothing
in this  Agreement  shall  relieve the Company of its  obligations  to Executive
under any other  agreement,  plan,  contract or arrangement.  Subject to Section
12.6  hereof,  no right,  benefit  or  interest  hereunder  shall be  subject to
anticipation,   alienation,  sale,  assignment,   encumbrance,  charge,  pledge,
hypothecation  or set-off in respect  of any claim,  debt or  obligation,  or to
execution,  attachment,  levy or similar  process or  assignment by operation of
law. Any attempt,  voluntary or involuntary,  to effect any action  specified in
the immediately  preceding  sentence shall, to the full extent permitted by law,
be null, void and of no effect.  In no event shall the Executive be obligated to
seek  other  employment  or take any other  action by way of  mitigation  of the
amounts  payable to the Executive  under any of the provisions of this Agreement
and, except as otherwise  provided in Section 4.2(b) hereof,  such amounts shall
not  be  reduced  whether  or  not  the  Executive   obtains  other  employment.
Notwithstanding  anything to the  contrary in this  Agreement,  Executive  shall
forfeit all future  payments and benefits  hereunder in the event that Executive
is determined, pursuant to procedures established in Section 4.6 hereof, to have
materially  breached any written covenant or agreement between the Executive and
the Company prohibiting the disclosure of confidential information pertaining to
the Company or respecting competition or interference with the Company, provided
that the Company  shall have given the Executive at least thirty (30) days prior
written  notice of such breach and such breach  shall not have been cured by the
end of such notice period.

         12.5.  Remedies.  The Company and Executive agree that,  because of the
unique nature of this  Agreement,  failure of either party to carry out or abide
by  the  obligations  under  this  Agreement  could  cause  irreparable  injury;
accordingly, the parties agree that, in addition to any other remedies available
to either  party,  any such  failure by either party to perform or abide by this
Agreement shall be subject to appropriate equitable remedies, including specific
performance and injunctive relief.

         12.6.  Assignability.  No right or interest to or in any payments shall
be assignable by the Executive; provided, however, that this provision shall not
preclude him from  designating one or more  beneficiaries  to receive any amount
that  may  be  payable  after  his  death  and  shall  not  preclude  the  legal
representative of his estate from assigning any right hereunder to the person or
persons  entitled  thereto under his will or, in the case of  intestacy,  to the
person or persons entitled thereto under the laws of intestacy applicable to his
estate.  The  term  "beneficiaries"  as  used  in this  Agreement  shall  mean a
beneficiary or beneficiaries so designated to receive any such amount,  or if no
beneficiary has been so designated,  the legal representative of the Executive's
estate.

         12.7.  Counterparts;  Headings;  References.  This  Change  in  Control
Agreement  may be executed in two or more  counterparts,  each of which shall be
deemed an original,  but all of which together shall constitute one and the same
instrument.  The  headings of the  sections of this  Agreement  are inserted for
convenience  only and shall not  constitute  a part  hereof.  References  to the
masculine or feminine  gender (or to the singular or plural number) herein shall
mean the other such gender (or number), as appropriate.

         12.8. Entire Agreement.  This instrument  contains the entire agreement
of the parties  pertaining to the subject matter contained herein and supersedes
and is in lieu  of any and all  other  arrangements  pertaining  to the  subject
matter contained herein having effect as of the effective date.

         12.9.  Notices.  All notices  given  hereunder  shall be in writing and
shall be delivered  personally or sent by prepaid  registered or certified mail,
return receipt  requested,  addressed as follows or to such other address as may
