Item 2.

On May  28,  1997,  Polaris  Investment  Management  Corporation  (the  "General
Partner"  or  "PIMC"),  on  behalf  of  Polaris  Aircraft  Income  Fund  VI (the
"Partnership"), executed definitive documentation for the purchase of all of the
Partnership's 2 remaining  aircraft (the "Aircraft") by Triton Aviation Services
VI LLC, a special purpose company (the "Purchaser").  The final closings for the
purchase of 1 of the 2 Aircraft had occurred as of June 6, 1997.  The  Purchaser
is managed by Triton Aviation Services,  Ltd. ("Triton  Aviation"),  a privately
held aircraft  leasing  company which was formed in 1996 by Triton  Investments,
Ltd., a company which has been in the marine cargo  container  leasing  business
for 17 years and is diversifying its portfolio by leasing  commercial  aircraft.
Each Aircraft was sold subject to the existing leases.

The General Partner's Decision To Approve The Transaction

In  determining  whether  the  transaction  was in  the  best  interests  of the
Partnership  and its  unitholders,  the General Partner  evaluated,  among other
things, the risks and significant expenses associated with continuing to own and
remarket  the  Aircraft  (one of which was  subject to a lease that was  nearing
expiration).  The General Partner  determined that such a strategy could require
the  Partnership  to  expend a  significant  portion  of its cash  reserves  for
remarketing  and that  there was a  substantial  risk that this  strategy  could
result  in the  Partnership  having  to  reduce  or  even  suspend  future  cash
distributions  to limited  partners.  The  General  Partner  concluded  that the
opportunity to sell both the Aircraft at an attractive price would be beneficial
in the present  market where demand for Stage II aircraft is  relatively  strong
rather  than  attempting  to sell the  aircraft  over the coming  years when the
demand  for  such  Aircraft  might be  weaker.  During  the  months  of  intense
negotiations,  GE Capital  Aviation  Services,  Inc.  ("GECAS"),  which provides
aircraft  marketing and management  services to the General  Partner,  sought to
obtain the best price and terms  available for these Stage II aircraft given the
aircraft market and the conditions and types of planes owned by the Partnership.
Both the General  Partner and GECAS  approved the sale terms of the Aircraft (as
described  below)  as being  in the best  interest  of the  Partnership  and its
unitholders  because  both  believe  that this  transaction  will  optimize  the
potential cash  distributions to be paid to limited partners.  To ensure that no
better offer could be obtained, the terms of the transaction negotiated by GECAS
included a "market-out"  provision  that  permitted the  Partnership to elect to
accept an offer for all (but no less than all) of the assets to be sold by it to
the Purchaser on terms which it deemed more  favorable,  with the ability of the
Purchaser to match the offer or decline to match the offer and be entitled to be
compensated in an amount equal to 1 1/2% of the  Purchaser's  proposed  purchase
price.

On April 7, 1997,  the General  Partner  received and on May 14, 1997 elected to
accept a competing offer (the "Competing  Offer") from a third party to purchase
the  Partnership's  two aircraft for $7,115,600 in cash,  subject to a number of
contingencies.  On May 21, 1997,  the  Purchaser  was notified of the  Competing
Offer, and the Purchaser subsequently matched the Competing Offer.

As a result of the sale of the Aircraft,  the General Partner will be winding up
the  Partnership's  operations  and  the  Partnership  may be in a  position  to
dissolve before December 31, 1997.

The Terms of the Transaction

The total purchase  price (the "Purchase  Price") to the Purchaser is $7,115,600
all of which is allocable to the Aircraft. The Purchaser is not receiving any of
the Partnership's  cash reserves,  estimated to be approximately  $900,000 after
the  anticipated  July  cash  distribution  is made  to  limited  partners.  The
Purchaser  paid into an escrow  account the Purchase Price of $7,115,600 in cash
at the closing. As described below, this transaction will enable the Partnership
to distribute to limited  partners the cash payment  received on the sale of the
Aircraft  and  permit  the  Partnership  to  distribute  to  limited  partners a
substantial portion of cash reserves which have been held by the Partnership.


                                        2

<PAGE>



The  Partnership  intends  to make  this  distribution  as part of its July 1997
quarterly distribution to limited partners.

Polaris  Aircraft  Income Fund II,  Polaris  Aircraft  Income Fund III,  Polaris
Aircraft  Income  Fund IV and  Polaris  Aircraft  Income  Fund V have  also sold
certain  aircraft  assets to separate  special  purpose  companies  under common
management with the Purchaser.

The   Purchaser   purchased   the  Aircraft   effective  as  of  April  1,  1997
notwithstanding  the actual closing dates.  The utilization of an effective date
facilitated the determination of rent and other allocations between the parties.
The Purchaser has the right to receive all income and proceeds,  including rents
and  receivables,  from the Aircraft  accruing  from and after April 1, 1997 and
will pay interest at the rate of 5.3% from April 1, 1997 on the  purchase  price
amount to the date of payment.

Neither PIMC nor GECAS will receive a sales  commission in  connection  with the
transaction.  Neither PIMC nor GECAS or any of its affiliates holds any interest
in Triton  Aviation or any of Triton  Aviation's  affiliates.  John  Flynn,  the
current President of Triton Aviation, was a Polaris executive until May 1996 and
has over 15 years experience in the commercial  aviation  industry.  At the time
Mr. Flynn was employed at PIMC, he had no  affiliation  with Triton  Aviation or
its affiliates.


With  respect  to the 1  Aircraft  that  has not  yet  been  transferred  to the
Purchaser  as of  June 6,  1997,  the  Partnership  has  agreed  to  obtain  the
Purchaser's  consent before undertaking any significant action, such as making a
material modification or waiving a default under a lease.

Anticipated July Cash Distribution

The Partnership  anticipates  making a cash distribution to the limited partners
of approximately  $8,764,023  ($126.25 per limited partnership unit) by July 30,
1997. Such distribution would be comprised of (i) the cash payment received from
the sale of the Aircraft,  less  estimated  transaction  expenses  (representing
approximately  $95.00 per limited partnership unit); and (ii) the portion of the
Partnership's  cash reserves which the General Partner  determined was available
for  distribution  (representing  approximately  $31.25 per limited  partnership
unit). The foregoing  anticipated  distribution is based on the assumptions that
the  closings for all the Aircraft  being sold to the  Purchaser  occur prior to
July 1,  1997,  the  Partnership  timely  receives  all  payments  due  from the
Purchaser and the  Partnership  incurs  estimated  operating and  administrative
expenses   (including   expenses  in  connection   with  the   transaction)   of
approximately  $53,000 for the quarter  ended June 30, 1997.  The  Partnership's
estimated cash  distributions  to limited partners  constitutes  forward looking
information  based  upon the  above  assumptions  that  may,  for any  number of
reasons, not occur. Accordingly,  there can be no assurance that the Partnership
will make a cash distribution in the amount anticipated.

Estimated Cash Reserves

The  Partnership  estimates  its cash reserves  will be  approximately  $900,000
($12.32 per limited  partnership  unit) after the cash  distribution  to limited
partners  anticipated  to be made in July  1997.  PIMC has  determined  that the
Partnership maintain these cash reserves as a prudent measure to insure that the
Partnership has available funds for other  contingencies  including  expenses of
the Partnership in connection  with winding up its affairs. 

Upon  determination  and  payment  of  remaining  operating  and  administrative
expenses of the Partnership after June 30, 1997 and expenses associated with the
winding up of the  Partnership,  which cannot be estimated at this time, a final
distribution of the remaining cash reserves,  if any, will be distributed to the
partners. The General Partner anticipates that such payment of expenses and cash



                                        3

distributions to partners will be completed by December 31, 1997, although there
can be no assurance that the Partnership  will be able to wind up its operations
by December 31, 1997.

                    This PURCHASE,  ASSIGNMENT AND ASSUMPTION  AGREEMENT (as the
same  may  be  amended,  modified  or  supplemented  from  time  to  time,  this
"Agreement"),  dated as of April 1, 1997,  is by and  between  POLARIS  AIRCRAFT
INCOME  FUND VI, a  California  limited  partnership  ("Assignor"),  and  TRITON
AVIATION SERVICES VI LLC, a California limited liability company ("Assignee").

                              W I T N E S S E T H:

                    WHEREAS, Assignor desires to sell and assign to Assignee and
Assignee  desires to purchase and assume from Assignor all of Assignor's  right,

                    (b)    Transfer of Aircraft Income and Lessee Deposits

                           For each  Daylight  Effective  Time and on the Mop-Up
Date, contemporaneously with such Daylight Effective Time or on the Mop-Up Date,
and for each Effective  Time that does not constitute a Daylight  Effective Time
or is not deemed to occur on the Mop-Up Date,  promptly at the  beginning of the
next  Business  Day after such  Effective  Time,  Assignor  shall wire  transfer
immediately  available funds to Assignee, at an account designated in writing by
Assignee,  in an  amount  equal  to the  Aircraft  Income  and  Lessee  Deposits
estimated by Assignor  pursuant to Section  4(d)(i) hereof to constitute part of
the  Transferred  Interest  transferred (or deemed to be transferred) as of such
Effective Time or as of the Mop-Up Date.

                    (c)    First Effective Date; Mop-Up Date

                           Each of Assignor  and Assignee  covenants  and agrees
that (i) if each of the  conditions  precedent in Section 7 (as to Assignor) and
each of the conditions  precedent in Section 8 (as to Assignee) are satisfied or
waived by the  appropriate  party,  the first  Effective  Time will occur on the
Start Date and (ii) the Effective Time for each and every  Transferred  Interest
will occur not later than the close of business in New York on the Mop-Up  Date.
Each of Assignor and Assignee  further  agrees that after the  occurrence of the
Effective Time for the remaining  Transferred  Interest,  (A) Assignor is hereby
authorized  to withdraw  from the Cash  Account,  an amount equal to the Release
Amount  for such  Transferred  Interest  less  one-half  of the fees owed to the
Escrow Agent and (B)  Assignee is hereby  authorized  to withdraw  from the Cash
Account  all other funds in excess of the amount set forth in clause (A). If the
Mop-Up Date has not occurred by the Outside Date, any Transferred Interest which
has not been  transferred  to  Assignee  will no longer be the  subject  of this
Agreement, this Agreement will be deemed to be reformed to delete all references
to such  Transferred  Interest,  the Purchase Price will be reduced in an amount
equal to the Release  Amount for such Transferred  Interest and on July 1, 1997,
Assignee is hereby authorized to withdraw all amounts out of the Cash Account.

                    (d)    Settlement of Aircraft Income and Lessee Deposits

                           (i) Prior to assignment of a Transferred  Interest to
Assignee  hereunder,  Assignor shall estimate the Aircraft Income and any Lessee
Deposits that have been  received by Assignor or the Owner  Trustee  relating to
such  Transferred  Interest  as  of  the  applicable  Effective  Time  for  such
Transferred  Interest.  Because the actual amount of the Aircraft Income and any
Lessee Deposits  relating to a Transferred  Interest and received by Assignor or
such Owner Trustee will not be readily  determinable  until after the applicable
Effective  Time,  a final  calculation  cannot be made on that date.  Therefore,
within  fifteen  (15)  Business  Days  after the end of the month in which  such
Effective  Time  occurs,   Assignor  shall  provide  Assignee  with  such  final
calculation  (in reasonable  detail) of Aircraft  Income and any Lessee Deposits
that have been  received  by  Assignor  or the Owner  Trustee  relating  to such
Transferred  Interest.  To the extent the calculation indicates that the amounts
transferred  by Assignor  pursuant to Section  4(b) hereof with  respect to such

                                       11
<PAGE>








Transferred Interest were in excess of the actual Aircraft Income and any Lessee
Deposits  received by Assignor or the Owner Trustee relating to such Transferred
Interest,  Assignee  shall  promptly  pay the amount of such  excess to Assignor
(plus  interest on such amount at the rate of 5.3% per annum from the applicable
date of payment to Assignee to the date of repayment to Assignor). To the extent
the calculation  indicates that the amounts  transferred by Assignor pursuant to
Section 4(b) hereof with respect to such Transferred Interest were less than the
actual Aircraft Income and any Lessee Deposits received by Assignor or the Owner
Trustee relating to such Transferred  Interest,  Assignor shall promptly pay the
amount of such  deficiency to Assignee (plus interest on such amount at the rate
of 5.3% per annum from the Business Day following the applicable  Effective Time
to the date of payment to Assignee).  An  adjustment  to the Purchase  Price for
Aircraft  Income under this Section 4(d)(i) shall be treated by the parties as a
purchase price adjustment for all income tax purposes.

                           (ii) If at any time prior to the last  Effective Time
to occur  pursuant  to the terms  hereof,  any  Aircraft  which is  subject of a
Transferred Interest not yet transferred by Assignor to Assignee suffers a Total
Loss,  such  Aircraft  will no longer be the subject of this  Agreement and this
Agreement  will be  deemed  to be  reformed  to delete  all  references  to such
Aircraft and the related Transferred  Interests;  provided,  however,  that with
respect to any such  Aircraft,  if such Total Loss is due to a Loss of Title and
if Assignor  cures or  otherwise  corrects  such Loss of Title by  regaining  or
recovering the use thereof or title thereto on or prior to the Mop-Up Date, such
Aircraft will be deemed to be reinstated and once more subject to this Agreement
and this  Agreement  will be deemed to be  reformed  to include  all  previously
deleted  references  to such  Aircraft  and the related  Transferred  Interests.
Contemporaneously  with the  removal  of any  Aircraft  from  the  terms of this
Agreement,  the Purchase Price will be reduced in an amount equal to the Release
Amount  applicable  to the  Transferred  Interest  relating  to  such  Aircraft.
Contemporaneously with the reinstatement of an Aircraft into this Agreement, the
Purchase  Price  will be  increased  in an amount  equal to the  Release  Amount
applicable to the Transferred Interest relating to such Aircraft. If at any time
prior to the last  Effective  Time to occur  pursuant to the terms  hereof,  any
Aircraft  which is subject of a  Transferred  Interest  not yet  transferred  by
Assignor to Assignee  suffers any  property  damage or loss not  constituting  a
Total Loss and such property  damage or loss is not cured or corrected  prior to
the time  when  such  Transferred  Interest  is  transferred  (or  deemed  to be
transferred)  by  Assignor  to  Assignee,  Assignor  shall pay to  Assignee  any
insurance  proceeds received by Assignor with respect to such property damage or
loss promptly  after receipt by Assignor of such insurance  proceeds;  provided,
however,  that  Assignor  shall not enter into any  settlement  of any insurance
claim  without the prior written  consent of Assignee,  which consent may not be
unreasonably withheld.

                           Assignor  hereby  covenants and agrees upon demand of
Assignee to pay and assume liability for, and indemnify,  protect,  defend, save
and keep  harmless  Assignee  and each of its  Affiliates  and in each such case
their  respective  directors,  officers,  employees  and agents  (the  "Assignee
Indemnitees"), on an After-Tax Basis, from and against any and all Damages which
may at any time or from time to time be imposed  upon,  incurred  by or asserted
against  any  of the  Assignee  Indemnitees  in any  way  relating  directly  or
indirectly  to,  or  arising  out  of,  (i)  any  inaccuracy  or  breach  of any
representation  or  warranty  made  by  Assignor  under  this  Agreement  or any
Ancillary Agreement to which it is a party, (ii) the ownership,  leasing, use or
operation of any Transferred  Interest prior to the Effective Time applicable to
such  Transferred  Interest  including,   without  limitation,  any  obligations
relating to the Trust Estate or any of the Operative Agreements relating to such
Transferred Interest which arise from acts,  omissions,  events or circumstances
occurring  or  accruing  prior  to the  Effective  Time  with  respect  to  such
Transferred  Interest  but not  including  any  Assumed  Liabilities,  (iii) the
failure of  Assignor  to perform or observe  any of its  obligations  under this
Agreement  or  any  Ancillary  Agreement  to  which  it  is a  party,  (iv)  any
litigation, claim or action brought by a limited partner of Assignor against any
Assignee  Indemnitee  to the extent such  litigation,  claim or action  directly
arises out of and relates to the  transactions  contemplated  by this  Agreement
other than to the extent any  litigation,  claim or action  relates  directly or
indirectly  to, or arises out of, the breach by such Assignee  Indemnitee of the
terms of this Agreement or any Ancillary Agreement or (v) any Liens set forth on
Schedule  5(h) hereto;  provided  that (a) Assignor  shall not be liable for any
Damages to the extent that  Assignee  has a recovery  available  to it under any
insurance  policy  which was in effect on or prior to the  applicable  Effective
Time; (b) Assignor shall not be liable for any Damages attributable to the gross
negligence or willful misconduct of Assignee or its Affiliates; and (c) Assignor
shall  not  be  liable  for  any  Damages  in  excess  of  the  Purchase  Price.
Notwithstanding the foregoing, Assignor shall be liable pursuant to this Section
12(c) only to the extent that the aggregate  cumulative  Damages incurred by the
Assignee  Indemnitees  which are required to be indemnified  by Assignor  exceed
$50,000 (the  "Threshold  Amount") in which event,  Assignor  shall then also be
liable for the initial $50,000 of aggregate  cumulative  Damages incurred by the
Assignee  Indemnitees;  provided,  that,  with  respect to any Lien set forth on
Schedule 5(h) hereto,  (x) the Threshold  Amount  limitation shall not apply and
Assignor shall be liable for all Damages arising from such Liens and (y) amounts
expended by Assignor to discharge  and release  such Liens shall not  constitute
Damages to be applied toward the Threshold  Amount and only those  expenses,  if
any,  actually incurred by Assignee in connection with such discharge or release
shall be so applied.

                    (d)    Assignee's Indemnity

                           Assignee  hereby  covenants and agrees upon demand of
Assignor to pay and assume liability for, and indemnify,  protect,  defend, save
and keep  harmless,  Assignor and each of its  Affiliates  and in each such case
their  respective  directors,  officers,  employees  and agents  (the  "Assignor
Indemnitees"), on an After-Tax Basis, from and against any and all Damages which
at any time or from time to time may be imposed  upon,  incurred  by or asserted
against the Assignor  Indemnitees in any way relating directly or indirectly to,

Effective  Time  applicable  to such  Transferred  Interest  including,  without
limitation, any obligations relating to the Trust Estate or any of the Operative
Agreements  relating  to  such  Transferred  Interest  which  arise  from  acts,
omissions,  events  or  circumstances  occurring  or  accruing  on or after  the
Effective Time with respect to such Transferred  Interest,  (iii) the failure of
Assignee or any of its Affiliates to perform or observe any of their  respective
obligations  under this Agreement or any Ancillary  Agreement to which it or any
of  its  Affiliates  is a  party,  (iv)  any  Assumed  Liabilities  or  (v)  any
modification,  amendment  or other  change  to any of the  Operative  Agreements
entered into by Assignee, or to which Assignee consents or forbears, in any such
case  without  the prior  written  consent of Assignor  (such  consent not to be
unreasonably  withheld)  that  affects  any of the  Reserved  Rights;  provided,
however,  that with respect to any Transferred  Interest which includes a Lease,
such indemnification  obligation shall only relate to modifications,  amendments
or other changes made or agreed to during the period  beginning on the Effective
Date  applicable  to such  Transferred  Interest  and ending on the date that is
twenty-four  (24) months  after the  termination  of the Lease  included in such

                    (e)    Survival of  Representations and Warranties

                           All  representations  and  warranties  of the parties
hereto  contained in this Agreement  (including all Schedules  hereto) or in any
document,  statement,  certificate  or other  instrument  referred  to herein or
delivered at the applicable  Effective Time in connection with the  transactions
contemplated  hereby, that (i) relate to any Transferred Interest which includes
a Lease,  shall survive until the later of (A) twenty-four (24) months after the
Effective Time applicable to such Transferred Interest or (B) twelve (12) months
after the  expiry of the Lease  included  in such  Transferred  Interest  (which
period shall not be deemed to include any renewals,  extensions or continuations
of such Lease), (ii) relate to any Transferred Interest which does not include a
Lease,  shall survive  until  twenty-four  (24) months after the Effective  Time
applicable to such Transferred Interest and (iii) do not relate to a Transferred

SECTION 13.         Indemnification Procedure

                    (a) Any  Assignee  Indemnitee  or Assignor  Indemnitee  (the
"Indemnified Party") seeking  indemnification  hereunder shall give to the party
obligated under this Agreement to provide  indemnification  to such  Indemnified
Party (the  "Indemnitor")  a notice  ("Claim  Notice")  describing in reasonable
detail the facts  giving rise to its claim for  indemnification  hereunder,  and
shall  include  in such  Claim  Notice  (if then  known) the amount or method of
computation of the amount of the claim, and a reference to the provision of this
Agreement or any other agreement,  document or instrument executed and delivered
hereunder or in  connection  herewith  upon which such claim is based;  provided
that a Claim Notice in respect of any action at law or suit in equity against an
Indemnified Party by a third party, as to which  indemnification  will be sought
(a "Third Party  Action"),  shall be given  promptly after the action or suit is
commenced;  provided, further, that failure of the Indemnified Party to give the
Indemnitor  prompt  notice in respect of any such Third Party Action as provided
herein shall not relieve the Indemnitor of its obligations hereunder,  except to
the  extent  such  Indemnitor  shall  have been  materially  prejudiced  by such
failure.

                    (b) The Indemnitor  shall be entitled (but not obligated) to
assume the defense or settlement  of such Third Party Action,  or to conduct any
negotiations  or  proceedings  to settle or otherwise  eliminate any Third Party
Claim  and shall  pay the  reasonable  fees and  disbursements  of such  counsel
related to such Third Party Action.  If the Indemnitor  assumes any such defense
or settlement or any such negotiations, it shall pursue such defense, settlement
or  negotiations  in good  faith.  If the  Indemnitor  fails to elect in writing
within 30  Business  Days of the  notification  referred to above to assume such
defense, the Indemnified Party may engage counsel to defend, settle or otherwise
dispose  of such  action  or  proceeding,  which  counsel  shall  be  reasonably
satisfactory to the Indemnitor.  In any such Third Party Action, any Indemnified
Party shall have the right to retain its own counsel,  but the fees and expenses
of such counsel shall be at the expense of such Indemnified Party unless (i) the
Indemnitor and the Indemnified Party shall have mutually agreed to the retention
of such counsel or (ii) the named parties to any such proceeding  (including any
impleaded  parties)  include both the Indemnitor and the  Indemnified  Party and
representation  of both the  Indemnitor  and the  Indemnified  Party by the same
counsel would be inappropriate  due to actual or potential  differing  interests
between them. It is understood that the Indemnitor shall not, in connection with
any Third Party Action or related  Third Party Action in the same  jurisdiction,
be liable for the fees and expenses of more than one separate  firm (in addition
to local  counsel)  for all  Persons to be  indemnified  pursuant to Section 12;
provided that the Indemnitor will be so liable if (x) the Indemnified  Party has
reasonably  concluded that there may be legal  defenses  available to it in such
Third Party Action that are different from or in addition to those  available to
the  Indemnitor  or (y) a conflict  or  potential  conflict  exists  between the
Indemnified  Party and the  Indemnitor in such Third Party Action (in which case
the Indemnitor will not have the right to direct the defense of such Third Party
Action with respect to which such conflict  exists on behalf of the  Indemnified
Party), but only to the extent such fees and expenses are incurred in connection
with such  conflicting  issues.  Any such  separate  firm shall be designated in
writing by the  Indemnified  Party.  The Indemnitor  shall not be liable for any
settlement  of any  proceeding of such Third Party Action  effected  without its
written  consent,  but if the Indemnitor  consents to any such  settlement,  the
Indemnitor  agrees to indemnify the Indemnified  Party from and against any loss
or liability for which  indemnity is available  hereunder and which is specified
in such settlement or judgment.  No Indemnitor shall,  without the prior written
consent  of the  Indemnified  Party  (which  consent  shall not be  unreasonably

                                       31
<PAGE>








withheld  or  delayed),  effect any  settlement  of any  pending  or  threatened
proceeding  in  respect of which any  Indemnified  Party is or could have been a
party and indemnity could have been sought hereunder by such Indemnified  Party,
unless such settlement  includes an  unconditional  release of such  Indemnified
Party  from  all  liability  or  claims  that  are the  subject  matter  of such
proceeding and such settlement only involves the payment of money.

                    (c)  Assignor  shall  be  entitled  in all  cases  (but  not
obligated) to assume the settlement and to conduct  negotiations  or proceedings
to obtain the discharge and release of or otherwise eliminate any Lien set forth
on Schedule  5(h) hereto.  If Assignor  assumes any such  settlement or any such
negotiations,  it shall pursue such  settlement or  negotiations  in good faith.
Assignor  shall not be liable for any  settlement  or discharge of any such Lien
effected without its written consent, but
if Assignor  consents to any such  settlement or discharge,  Assignor  agrees to
indemnify Assignee from and against any loss or liability for which indemnity is
available hereunder and which is specified in such settlement or discharge.

                  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

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


<PAGE>






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.

                  (a)  The  Escrow  Agent  shall   exercise   ordinary  care  in
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


<PAGE>






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.

New York and of any Federal  Court  located in the Borough of  Manhattan in such
State in connection with any action,  suit or other proceeding arising out of or

                           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
                           administrative    duties   as   stipulated   in   the

                           eligible  investments at the direction of the client,
                           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
         rendered.
