and hold the Escrowed  Property (as hereinafter  defined) in accordance with the
terms and conditions hereof.

                  NOW,  THEREFORE,  for good  and  valuable  consideration,  the
receipt  and  adequacy of which are hereby  acknowledged  by each of the parties

                  1.  Appointment of  Escrow  Agent.  Polaris and Triton  hereby
appoint  Bankers Trust Company as escrow agent in accordance  with the terms and
conditions  set  forth  herein,   and  the  Escrow  Agent  hereby  accepts  such
appointment.

                  2.  Deposit into  the  Escrow Fund.Triton, simultaneously with
the  execution  and delivery of this  Agreement,  has  deposited or caused to be
deposited  with  the  Escrow  Agent  the  sum of  $7,116,600  (of  which  $1,000
represents  one-half of the Escrow  Fees (as defined in  paragraph 8 hereof)) in
immediately  available funds  (together with any interest  earned  thereon,  the
"Escrowed  Property"),  the receipt of which will be  acknowledged by the Escrow
Agent,  and which  Escrowed  Property shall be held by the Escrow Agent upon the
terms and conditions hereinafter set forth.











                  3.  Deposit of Escrowed Property.

                  (a) During  the term of this  Agreement,  the Escrow  Agent is
hereby  directed to deposit the  Escrowed  Property  and any  interest or income
earned thereon in the BT Institutional Cash Management Fund.

                  (b) The Escrow Agent shall not have any liability for any loss
sustained as a result of any investment made as provided above,  any liquidation
of any such  investment  prior to its maturity,  or the failure of an authorized
person of the Company to give the Escrow Agent any written instruction to invest
or reinvest the Escrowed Funds or any earnings thereon.

                  4.   Distribution of Escrowed Property.

                  (a) The Escrow Agent shall hold the  Escrowed  Property in its
possession  until instructed  hereunder to deliver the Escrowed  Property or any
specified portion thereof as provided in paragraph 4(b) below.

                  (b)  At  such  time  as  Polaris  delivers  a  written  notice
substantially  in the form of Exhibit A hereto  (the  "Release  Notice")  to the
Escrow Agent,  signed by an authorized  representative of Polaris,  stating that
the  requirements  under the  Purchase  Agreement  for  release of the  Escrowed
Property have been met, the Escrow Agent shall  promptly  disburse to Polaris to
the account specified by Polaris in the Release Notice,  the amount set forth in
the Release  Notice  (which  amount shall be the Cash Amount,  as defined in the
Purchase  Agreement),  less  one-half of the Escrow  Fees  payable to the Escrow
Agent  hereunder,  and shall  disburse the balance of the  Escrowed  Property to
Triton to an account specified by Triton to the Escrow Agent.

                  (c) The  Escrow  Agent is  acting as a  stakeholder  only with
respect to the Escrowed Property. If any dispute arises as to whether the Escrow
Agent is obligated  to deliver the Escrowed  Property or as to whom the Escrowed
Property is to be delivered or the amount thereof, the Escrow Agent shall not be
required to make any  delivery,  but in such event the Escrow Agent may hold the
Escrowed  Property until receipt by the Escrow Agent of instructions in writing,
signed by all parties  which have, or claim to have, an interest in the Escrowed
Property,  directing the disposition of the Escrowed Property, or in the absence
of such  authorization,  the Escrow Agent may hold the Escrowed  Property  until
receipt  of a  certified  copy  of a final  judgment  of a  court  of  competent
jurisdiction  providing for the disposition of the Escrowed Property. The Escrow
Agent may require,  as a condition to the  disposition of the Escrowed  Property
pursuant to written instructions, indemnification and/or opinions of counsel, in
form and substance  satisfactory to the Escrow Agent,  from each party providing
such instructions.  If such written  instructions,  indemnification and opinions




                                        2









are not received,  or  proceedings  for such  determination  are not  commenced,
within 30 days after  receipt by the Escrow  Agent of notice of any such dispute
and diligently continued,  or if the Escrow Agent is uncertain as to which party
or parties are  entitled to the Escrowed  Property,  the Escrow Agent may either
(i) hold the Escrowed  Property until receipt of such written  instructions  and
indemnification  or a certified copy of a final judgment of a court of competent
jurisdiction  providing for the  disposition of the Escrowed  Property,  or (ii)
deposit  the  Escrowed  Property  in  the  registry  of  a  court  of  competent
jurisdiction;  provided, however, that notwithstanding the foregoing, the Escrow
Agent may,  but shall not be required to,  institute  legal  proceedings  of any
kind.

                  5.  Resignation  of Escrow Agent.  The Escrow Agent may resign
and be discharged from its duties hereunder at any time by giving written notice
of  such  resignation  to  Polaris  and  Triton  specifying  a  date  when  such
resignation  shall take effect and upon delivery of the Escrowed Property to the
successor  escrow agent  designated by all parties hereto (other than the Escrow
Agent) in writing. Upon such notice, a successor escrow agent shall be appointed
with the mutual consent of Polaris and Triton. Such successor escrow agent shall
become the escrow agent  hereunder upon the  resignation  date specified in such
notice.  If Polaris and Triton are unable to agree upon a successor escrow agent
within thirty (30) days after such notice, the Escrow Agent shall be entitled to
apply to a court of competent  jurisdiction  for the appointment of a successor.
The Escrow Agent shall continue to serve until its successor  accepts the escrow
and receives the Escrowed  Property.  Polaris and Triton shall have the right at
any time upon their  mutual  consent to  substitute a new Escrow Agent by giving
notice  thereof  to the Escrow  Agent  then  acting.  Upon its  resignation  (or
replacement)  and  delivery  of the  Escrowed  Property  as set  forth  in  this
Paragraph  5,  the  Escrow  Agent  shall be  discharged  of and from any and all
further  obligations  arising in connection with the escrow contemplated by this
Agreement.

                  6.  Indemnification of Escrow Agent.

fulfilling its duties and obligations hereunder.  The Escrow Agent shall have no
duties or  responsibilities  whatsoever  with respect to the  Escrowed  Property
except as are specifically  set forth herein.  The Escrow Agent shall neither be
responsible  for or  under,  nor  chargeable  with  knowledge  of the  terms and
conditions  of  any  other  agreement,  instrument  or  document  in  connection
herewith.  Except as otherwise  provided in  subsection  (b) hereof,  the Escrow
Agent  may  conclusively  rely  upon,  and  shall  be fully  protected  from all
liability,  loss, cost,  damage or expense in acting or omitting to act pursuant
to any written notice,  instrument,  request,  consent,  certificate,  document,
letter, telegram,  opinion, order, resolution or other writing hereunder without
being required to determine the  authenticity of such document,  the correctness
of any  fact  stated  therein,  the  propriety  of the  service  thereof  or the
capacity, identity or  authority of any party purporting to sign or deliver such




                                        3









document.  The Escrow Agent shall have no responsibility for the contents of any
such writing contemplated herein and may conclusively rely without any liability
upon the contents thereof.

                  (b) The Escrow  Agent shall not be liable for any action taken
or omitted by it in good faith and  reasonably  believed by it to be  authorized
hereby or with the rights or powers conferred upon it hereunder,  nor for action
taken or omitted by it in good faith,  and in accordance  with advice of counsel
(which  counsel  may be of the Escrow  Agent's own  choosing),  and shall not be
liable for any mistake of fact or error of judgment or for any acts or omissions
of any kind except for its own willful misconduct or negligence.

                  (c)  Polaris  and Triton  agree  severally  and not jointly to
indemnify the Escrow Agent and its employees, directors, officers and agents and
hold each harmless against any and all liabilities incurred by it hereunder as a
consequence of such party's action,  and both Polaris and Triton agree severally
and not jointly to indemnify  the Escrow Agent and hold it harmless  against any
and all liabilities incurred by it and them hereunder that are not a consequence
of any party's  action,  except in either case for  liabilities  incurred by the
Escrow  Agent  resulting  from its own  willful  misconduct  or  negligence.  In
connection  therewith,  Polaris  and Triton  shall each be liable for 50% of any
such liabilities.

                  7.  Compensation  of Escrow  Agent.  The Escrow Agent shall be
entitled to payment for customary fees and expenses for all services rendered by
it here under in accordance  with  Schedule B attached  hereto (as such schedule
may be  amended  from time to time by  Polaris,  Triton  and the  Escrow  Agent)
("Escrow  Fees").  The Escrow Agent shall also be entitled to  reimbursement  on
demand for all reasonable loss,  liability,  damage or expenses paid or incurred
by it in the administration of its duties hereunder,  including, but not limited
to, all reasonable counsel, advisors' and agents' fees and disbursements and all
taxes or other governmental charges.

                  8. Further Assurances. From time to time on and after the date
hereof,  the other parties  hereto shall deliver or cause to be delivered to the
Escrow Agent such further documents and instruments and shall do and cause to be
done such further acts as the Escrow  Agent shall  reasonably  request (it being
understood  that the  Escrow  Agent  shall have no  obligation  to make any such
request)  to carry out more  effectively  the  provisions  and  purposes of this
Agreement,  to  evidence  compliance  herewith  or to assure  itself  that it is
protected in acting hereunder.

                  9. Termination of Agreement. This Agreement shall terminate on
the final  disposition of the Escrowed  Property provided that the rights of the
Escrow Agent and the  obligations  of the other parties  hereto under Sections 6
and 7 shall survive the termination hereof and the resignation or removal of the
Escrow Agent.

                           standard   escrow   agreement.    Any   escrow   that
                           substantially   alters   the   agreement   may  incur
                           additional   costs   which  would  be  billed  as  an
                           acceptance fee.)

         B.       Annual Administrative Fee:  None.
                           (Payable   annually  in  advance.   Includes   normal

                           including ticket charges, custody and tax reporting.)

         D.       Wire Transfer Fee:  None.
                           (Pertains to outgoing wires only.)

         The  fees  set  forth  in  this  schedule  are  subject  to  review  of
         documentation. The fees are also subject to change should circumstances
         warrant.  As provided in the Escrow  Agreement,  reimbursement  for all
         out-of-pocket  expenses,  disbursements and fees of counsel  (including
         their  disbursements  and expenses)  incurred in the performance of the
         Escrow Agent's duties will be added to billed fees. Once appointed,  if
         the deal  should  fail to close for  reasons  beyond  our  control,  we
         reserve  the  right to  charge a fee not to  exceed  the  amount of our
         acceptance fee, and we will require reimbursement in full for our legal
         fees and any out-of-pocket expenses related to the deal.

         Fees  for any  services  not  specifically  covered  in  this or  other
         applicable  schedules  will  be  based  on  an  appraisal  of  services
