Item 2.

On May  28,  1997,  Polaris  Investment  Management  Corporation  (the  "General
Partner"  or  "PIMC"),  on  behalf  of  Polaris  Aircraft  Income  Fund  V  (the
"Partnership"),  executed definitive documentation for the purchase of all 12 of
the  Partnership's  remaining  aircraft  (the  "Aircraft")  by  Triton  Aviation
Services V LLC, a special purpose company (the "Purchaser").  The final closings
for the purchase of all 12 of the 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  (many of which were subject to leases that were 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 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  "one-by-one"  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 May 9, 1997, the General  Partner  received a competing offer (the "Competing
Offer") from a third party to purchase  the  Partnership's  twelve  aircraft and
certain notes receivable, subject to a number of contingencies,  as disclosed in
the Partnerships Quarterly Report to the Securities and Exchange Commission Form
10-Q at March 31, 1997.  The Competing  Offer  included a higher  purchase price
than the offer made by the Purchaser (the "Original Offer").  Both the Competing
Offer and the Original Offer contained similar financing structures, but the net
worth of the  company  submitting  the  Competing  Offer was  approximately  $11
million,  as  compared  to the  approximately  $150  million net worth of Triton
Investments,  Ltd., the parent of the Purchaser's Manager. On May 14, 1997, upon
review and  comparison  of the  Competing  Offer with the  Original  Offer,  the
General  Partner  determined  that it  would  be in the  best  interests  of the
Partnership to reject the Competing Offer due to the  significant  difference in
the net worth and the execution risks both at closing and thereafter, as well as
the  payment  of the 1 1/2% fee that  would be due to the  Purchaser  under  the
Original Offer representing approximately half of the premium represented by the
Competing Offer over the Original Offer.

The Terms of the Transaction

The total purchase price (the "Purchase  Price") to the Purchaser is $34,750,259
which is allocable to the  Aircraft.  The  Purchaser is not receiving any of the
Partnership's cash reserves,  estimated to be approximately $9,800,000 after the
anticipated July cash  distribution is made to limited  partners.  The Purchaser
paid into an escrow  account  $3,914,964  of the  Purchase  Price in cash at the
closing and delivered a promissory note (the "Promissory  Note") for the balance
of $30,835,295. As described below, this transaction will enable the Partnership
to distribute to limited  partners the cash down 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.
The  Partnership  intends  to make  this  distribution  as part of its July 1997
quarterly distribution to limited partners.

The  Promissory  Note is to be repaid  beginning  June 30, 1997 in 28  quarterly
installments of principal and interest in the amount of $1,512,367 over a period
of seven  years  bearing  interest  at a rate of 12% per  annum  with a  balloon
principal  payment  in the  amount  of  $5,621,617  due on March 31,  2004.  The
Purchaser has the right to voluntarily prepay the Promissory Note in whole or in
part at any time without penalty. In addition, the Promissory Note is subject to
mandatory partial prepayment in certain specified instances.

Under the terms of the transaction, the Purchaser's assets, which are limited to
the  Aircraft,  including any income or proceeds  therefrom,  and any funds made
available to Purchaser under the working capital line described below constitute
the sole  source of payments  under the  Promissory  Note.  Although no security
interest over the Aircraft or the leases is granted in favor of the Partnership,
the equity interests in the Purchaser have been pledged to the  Partnership.  In
connection  with  that  pledge,  the  Purchaser  is  prohibited  from  incurring
indebtedness other than (i) the Promissory Note; (ii) deferred taxes not yet due
and  payable;  (iii)  indebtedness  incurred  to hushkit  Aircraft  owned by the
Purchaser;  (iv) demand loans to another SPC (defined below) at a market rate of
interest;  and (v) debt to trade  creditors  incurred in the ordinary  course of
business. In addition,  the Purchaser undertakes to keep the Aircraft and leases
free of any lien, security interest or other encumbrance other than (i) inchoate
taxes and materialmen's liens and the like, (ii) in the event that the Purchaser
elects to install  hushkits on any  Aircraft,  secured debt to the extent of the
full cost of such hushkit and other  hushkits  acquired  with  proceeds from the
same loan facility;  (iii) liens lessees are customarily permitted to incur that
are  required  to be  removed.  The  Purchaser  has the right to sell any of the
Aircraft without the consent of the Partnership,  except that the  Partnership's
consent  would be  required  in the event  that the sale  price is less than the
portion of the outstanding  balance of the Promissory Note which is allocable to
the Aircraft in question and the  Purchaser  does not have  sufficient  funds to
make up the  difference.  In the event that any of the  Aircraft are sold by the
Purchaser,  the  Promissory  Note is subject to a  mandatory  prepayment  of the
portion of the Promissory Note which is allocable to the Aircraft sold.

Polaris  Aircraft  Income Fund II,  Polaris  Aircraft  Income Fund III,  Polaris
Aircraft  Income  Fund IV and  Polaris  Aircraft  Income  Fund VI have also sold
certain  aircraft  assets to separate  special  purpose  companies  under common
management with the Purchaser  (collectively,  together with the Purchaser,  the
"SPC's") on terms  similar to those set forth above,  with the  exception of the
Polaris Aircraft Income Fund VI aircraft, which were sold on an all cash basis.

Under the terms of the  transaction,  the Purchaser's  Manager has undertaken to
make  available a working  capital line to the Purchaser of up to  approximately
$4,034,000 to fund operating obligations of the Purchaser.  This working capital
line is guaranteed by Triton  Investments,  Ltd., the parent of the  Purchaser's
Manager and such  guarantor  provided  the  Partnership  with a copy of its most
recent  balance  sheet  showing  a  consolidated  net  worth  (net  of  minority
interests)  of at least  $150-million  at December 31, 1996.  Provided  that the
Purchaser is not in default in making payments due under the


                                        3

<PAGE>



Promissory  Note to the  Partnership,  the Purchaser is permitted to dividend to
its equity owners an amount not to exceed approximately  $108,000 per month. The
Purchaser may distribute additional dividends to the equity owners to the extent
of the working capital  advances made by the Purchaser's  Manager  provided that
the working capital line available to the Purchaser will be deemed  increased to
the extent of such dividends.

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
the Promissory Note commenced bearing interest as of April 1, 1997.

The Partnership continues to own the note receivable (the "AIA Receivable") from
American  International Airways Limited ("AIA") with a current principal balance
of $11,437,741 plus accrued  interest,  which had initially been included in the
assets  which  were  transferred  to the  Purchaser.  After  the  date  that the
Partnership and the Purchaser entered into the definitive  documentation for the
sale transaction,  but prior to the date that the AIA Receivable was transferred
to the Purchaser, AIA failed to make a scheduled principal payment under the AIA
Receivable  and  asked  the  Partnership  to  modify  and  restructure  the  AIA
Receivable.  As a result, the Partnership and the Purchaser agreed to modify and
reform the definitive  documentation for the sale transaction to exclude the AIA
Receivable.  The General Partner is currently assessing the request made by AIA.
The AIA  Receivable  is  secured  by a  mortgage  on a  Boeing  747-100  Special
Freighter aircraft.

Neither PIMC nor GECAS will receive a sales  commission in  connection  with the
transaction. In addition, PIMC will not be paid a management fee with respect to
the  collection  of the  Promissory  Note.  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,  has over 15  years  experience  in the  commercial
aviation  industry.  At the time Mr.  Flynn was  employed  at PIMC and he had no
affiliation with Triton Aviation or its affiliates.


Anticipated July Cash Distribution

The Partnership  anticipates  making a cash distribution to the limited partners
of approximately  $11,485,000  ($22.97 per limited partnership unit) by July 30,
1997. Such distribution would be comprised of (i) the cash down payment received
from the sale of the Aircraft, less estimated transaction expenses (representing
approximately  $6.75 per limited  partnership  unit);  (ii) the Promissory  Note
payment  due from the  Purchaser  on June 30, 1997  (representing  approximately
$2.72 per limited  partnership unit); and (iii) the portion of the Partnership's
cash reserves which the General Partner determined is available for distribution
(representing  approximately $13.50 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 $1,534,000 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  $9,800,000
($17.64 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 in the event the Purchaser  defaults under the
Promissory  Note  and  for  other   contingencies   including  expenses  of  the
Partnership.  The  Partnership's  cash  reserves  will be  monitored  and may be
revised  from  time to time as  further  information  becomes  available  in the
future.

                           Each of Assignor  and Assignee  covenants  and agrees
that  (i) if  each  of the  conditions  precedent  in  Section  7(a)-(r)  (as to
Assignor) or Section  8(a)-(l) (as to Assignee)  are  satisfied or waived by the
appropriate  party,  the first  Effective  Time  with  respect  to any  Aircraft

for each and every Aircraft  Transferred  Interest will occur not later than the

further  agrees that at any time after the  earlier of (i) the seventh  Business
Day after the Start Date and (ii) the last  Effective  Time to occur pursuant to
the terms  hereof,  (A) Assignor is hereby  authorized to withdraw from the Cash
Account,  an amount  equal to the Cash  Amount  less any  reduction  of the Cash

4(d)(ii)  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); provided, however, if Assignee withdraws the

then  Assignor  shall  promptly  return  to  Assignee  an  amount  equal to such
subsequent  reduction  plus  interest  at the  rate of 5.3% per  annum  from the
withdrawal  date through the date of repayment to Assignee.  On the Mop-Up Date,
so long as (i) the  conditions  precedent  set forth in Section 7 hereof  (other
than with respect to the location of the Aircraft)  shall have been satisfied or
waived by Assignor, Assignor shall be obligated to deliver, with respect to each
Aircraft  Transferred Interest that has not been assigned previously to Assignee
(including  any Aircraft  Transferred  Interest  which has not been  transferred
previously because the Aircraft relating to such Aircraft  Transferred  Interest
has been the  subject  of a Loss of Title but as to which such Loss of Title has
been cured or otherwise  corrected on or prior to the Mop-Up  Date),  Assignment
and Assumption  Agreements,  the evidence of authorization  described in Section
8(e)(iv),  any consents referred to in Section 5.1(b), the opinions described in
Section 8(i) and any other  instruments  or documents as Assignee or its counsel
shall reasonably request and (ii) the conditions  precedent set forth in Section
8 hereof  (other than with respect to the location of the  Aircraft)  shall have
been  satisfied or waived by Assignee,  Assignee  shall be obligated to deliver,
with respect to each  Aircraft  Transferred  Interest that has not been assigned
previously to Assignee  (including any Aircraft  Transferred  Interest which has
not been transferred  previously  because the Aircraft relating to such Aircraft
Transferred  Interest  has been the  subject  of a Loss of Title but as to which

                                       13
<PAGE>








such  Loss of Title has been  cured or  otherwise  corrected  on or prior to the
Mop-Up  Date),   Assignment   and   Assumption   Agreements,   the  evidence  of
authorization  described in Section 7(j)(v), any consents referred to in Section
6.1(b),  the opinions  described in Section  7(m) and any other  instruments  or
documents as Assignor or its counsel shall reasonably  request. If on the Mop-Up
Date any of the conditions  precedent set forth in Section 7 or Section 8 hereof
(other than with respect to the location of the  Aircraft)  are not satisfied or
waived  by  the  applicable  party  with  respect  to any  Aircraft  Transferred
Interest,  any Aircraft which is subject of such Aircraft  Transferred  Interest
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 such
Aircraft  Transferred  Interest  and the  Purchase  Price  will be reduced in an
amount equal to the Allocable  Portion  Percentage for such Aircraft and each of
the Note Amount and the Cash Amount as set forth on Schedule 4(a) hereof will be
adjusted on a pro rata basis.

                    (d)    Settlement of Income and Lessee Deposits

                           (i) Prior to assignment of a Transferred  Interest to
Assignee  hereunder,  Assignor shall estimate the 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  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 the 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  Transferred  Interest were
in excess of the actual 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  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 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 an
Aircraft  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  Aircraft  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
Aircraft  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 Allocable  Portion  Percentage for such Aircraft and each
of the Note Amount and the Cash Amount as set forth on Schedule 4(a) hereof will
be adjusted on a pro rata basis.  Contemporaneously with the reinstatement of an
Aircraft into this Agreement,  the Purchase Price will be increased in an amount
equal to the Allocable Portion Percentage for such Aircraft and each of the Note
Amount and the Cash Amount as set forth on Schedule 4(a) hereof will be adjusted
on a pro rata basis.  If at any time prior to the last  Effective  Time to occur
pursuant  to the terms  hereof,  any  Aircraft  which is subject of an  Aircraft
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  Aircraft
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.

to indemnify Assignee under any Operative Agreement and, thereafter,  shall upon
request keep  Assignor  apprised at least monthly of the progress of any protest
or proceeding in respect of such adjustment.

                    (c)    Assignor's Indemnity

                           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,  any of the  Operative  Agreements  or any of the
Receivable  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 13(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,
or  arising  out of,  (i) any  inaccuracy  or  breach of any  representation  or
warranty made by Assignee or any of its  Affiliates  under this Agreement or any
Ancillary  Agreement to which it or any of its  Affiliates is a party,  (ii) the
ownership, leasing, use or operation of any Transferred Interest on or after the
Effective  Time  applicable  to such  Transferred  Interest  including,  without
limitation,  any obligations  relating to the Trust Estate, any of the Operative
Agreements  or any of the  Receivable  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 or any of the  Receivable  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 Transferred  Interest (which
period shall be deemed to include any renewals,  extensions or  continuations of
such Lease). Notwithstanding the foregoing, (a) Assignee shall not be liable for
any Damages to the extent that Assignor has a recovery available to it under any
insurance  policy  which was in effect on or prior to the  Effective  Time;  (b)
Assignee  shall  not be  liable  for  any  Damages  attributable  to  the  gross
negligence or willful  misconduct of Assignor;  (c) Assignee shall not be liable
for any Damages in excess of the Purchase Price and (d) Assignee shall be liable
pursuant to this  Section  13(d) only to the extent that the  aggregate  Damages
incurred by the Assignor  Indemnitees  which are required to be  indemnified  by
Assignee  exceed $50,000 in which event,  Assignee shall then also be liable for
the initial  $50,000 of aggregate  cumulative  Damages  incurred by the Assignor
Indemnitees.

                    (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
Interest,  shall survive until twenty-four (24) months after the first Effective
Time to occur under this Agreement.

SECTION 14.         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 13;
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


                                       38
<PAGE>








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
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.

fulfill any of its obligations under this Agreement has been the cause of or has
resulted  in  the  failure  of  the  transactions   contemplated   hereby  being
consummated on or before the Outside Date; or

                    (c) by (i)  Assignor if (a) Assignor  accepts or  recommends
one or more  Superior  Proposals to its partners or resolves to do either of the
foregoing and (b) Assignee no longer has the right  pursuant to Section 11(c) to
deliver an  Assignee  Acceptance  Notice to  Assignor or (ii) by Assignee if (x)
Assignor has given an SP Notice and (y) at least  fourteen (14) days have passed
since the date on which Assignee's right pursuant to Section 11(c) to deliver an
Assignee Acceptance Notice terminated.

by and among POLARIS  AIRCRAFT INCOME FUND V, a California  limited  partnership
("Polaris"),  TRITON  AVIATION  SERVICES V LLC, a California  limited  liability
company ("Triton") and Bankers Trust Company, a New York banking corporation (as
escrow agent hereunder, the "Escrow Agent").

                              W I T N E S S E T H:

                  WHEREAS, the parties hereto, other than the Escrow Agent, have
entered into a Purchase,  Assignment and Assumption  Agreement dated as of April
1, 1997 (the "Purchase  Agreement") pursuant to which Polaris has agreed to sell
to Triton and Triton has agreed to purchase from  Polaris,  certain  assets,  as
provided therein (the "Assets"); and

                  WHEREAS,  pursuant  to  Section 4 of the  Purchase  Agreement,
Polaris  and  Triton  have  agreed  that  Triton  shall  deposit  or cause to be
deposited  the  purchase  price  for  the  Assets,  to be  held  in  escrow  and
distributed  in  accordance  with the  terms of this  Escrow  Agreement  and the
Purchase Agreement; and

                  WHEREAS,  the Escrow Agent is willing to serve as escrow agent
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
hereto,  the parties  hereto,  intending to be legally bound, do hereby agree as
follows:

                  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  $5,204,540  (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.


<PAGE>
                  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

                                  Prepared For
                                Escrow Agreement


         A.       Acceptance Fee:  $2,000 one time fee.
                           (Includes   acceptance  of  appointment,   review  of
                           documentation,  establishment of account and records.
                           This fee is  intended  to cover costs and set up of a
                           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
                           agreement.)

         C.       Investment Transactions:  None.
                           (Covers  all  costs   associated  with  investing  in
                           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

                  (b) No Pledgor  shall be  entitled  to collect and receive any
dividend or other  distribution paid in respect of the Pledged Interests whether
paid or payable in cash,  instruments or other property other than (1) beginning
as of April 1, 1997,  payable in the next calendar  month,  the Equity  Dividend
Amount  and any  accrued  and  unpaid  Equity  Dividend  Amount  for each  month
thereafter, (2) with respect to TASL only, amounts equal to equity contributions
made by TASL pursuant to the Keep Well which have not been  previously  recouped
through the payment of any dividend or  distribution by Borrower and (3) amounts
equal to any  reduction  of the Cash Amount  pursuant to Section 4(c) or Section
4(d)(ii) of the Purchase Agreement; provided, however, that during any period in
which any  payment  under the Note is overdue or a Default has  occurred  and is
continuing,  no Pledgor shall be entitled to collect and receive any dividend or
other  distribution  whatsoever  but Borrower may continue to accrue a liability
equal to the Equity  Dividend  Amount  during such period and  Borrower may make
payments in respect of any such accrued  liability so long as no amounts due and
payable under the Note are overdue and no Default thereunder is continuing,  and
provided,  further,  that any permitted dividends or distributions in respect of
the Pledged  Interests shall be paid only to the extent  permitted by applicable
law.

                  (c) Other than  dividends  and  distributions  permitted to be
received by a Pledgor  pursuant to subsection (b) above,  all dividends or other
distributions paid in respect of any of the Pledged Interests,  whenever paid or
made,  shall be delivered to Lender to hold as Pledged  Collateral and shall, if
received by such  Pledgor,  be  received in trust for the benefit of Lender,  be
segregated  from the other  property or funds of such Pledgor,  and be forthwith
delivered to Lender as Pledged  Collateral in the same form as so received (with
any necessary endorsement).

                  (d) (i)  Borrower  shall  be  permitted  to  issue  additional
Interests to any Person (each,  an "Additional  Holder") and (ii) each member of
Borrower shall be permitted to sell or otherwise  transfer Pledged  Interests to
any Person  (each,  a  "Transferee");  provided,  in each case that after giving
effect to any such  issuance or  transfer  (A) the number of members of Borrower
who are not Triton  Members  shall not exceed  three (3) as a result of any such
issuance or transfer,  (B) the Triton Members shall hold, in the  aggregate,  at
least 50% of the Economic  Interests of Borrower,  (C) the Additional  Holder or
Transferee  of such  equity  interest  shall  be a  Qualified  Holder,  (D) such
Additional  Holder or  Transferee  shall  expressly  agree to the pledge of such
Interests  under  this  Agreement  and to be bound by the terms  and  conditions
hereof by delivery of a duly executed Pledge Amendment,  and (E) after notice to
Lender by the  applicable  Pledgor,  pursuant to the terms of Section 19 hereof,
Lender  shall  consent to such  transfer  or  issuance,  such  consent not to be
unreasonably  withheld;  provided,  however,  that if Lender does not respond to
such notice  within ten (10) days after  receipt by Lender of such notice,  such
consent shall be deemed granted. Notwithstanding the foregoing, no such issuance
or transfer  shall be permitted if such  issuance or transfer  would violate any
applicable law or cause the Aircraft owned, directly or indirectly,  by Borrower
then registered  under the Act to no longer be eligible for  registration  under
the Act.

                  8. Defaults and Remedies.  (a) Upon the occurrence of an Event
of Default and during the continuation of such Event of Default,  then or at any
time  after  the  declaration  of such  Event of  Default  (provided  that  such
declaration  is not  rescinded by Lender) and following  written  notice to each
Pledgor,  Lender  (personally  or  through  an agent) is hereby  authorized  and
empowered to transfer and register in its name or in the name of its nominee the
whole or any part of the Pledged Collateral,  to exercise the voting rights with
respect  thereto,  to collect and receive all dividends and other  distributions
made  thereon,  to sell in one or more sales after seven (7) days' notice of the
time and place of any public sale or of the time after  which a private  sale is
to take place (which notice each Pledgor agrees is commercially reasonable), but
without  any  previous  notice  or  advertisement,  the whole or any part of the
Pledged  Collateral and to otherwise act with respect to the Pledged  Collateral
as though Lender was the outright owner thereof, each Pledgor hereby irrevocably
constituting  and appointing  Lender as the proxy and  attorney-in-fact  of such
Pledgor,  with full power of substitution to do so;  provided,  however,  Lender
shall not have any duty to exercise  any such right or to preserve  the same and
shall not be liable  for any  failure to do so or for any delay in doing so. Any
sale shall be made at a public or private sale at Lender's place of business, or
at any public  building in the City and County of San  Francisco or elsewhere to
be named in the  notice of sale,  either  for cash or upon  credit or for future
delivery at such price as Lender may deem fair,  and Lender may be the purchaser
of the  whole or any part of the  Pledged  Collateral  so sold and hold the same



                                       10



<PAGE>



thereafter  in its own right free from any claim of such Pledgor or any right of
redemption.  Each sale shall be made to the highest bidder,  but Lender reserves
the right to reject any and all bids at such sale which, in its  discretion,  it
shall  deem  inadequate.  Demands of  performance,  except as  otherwise  herein
specifically  provided for, notices of sale,  advertisements and the presence of
property at sale are hereby waived and any sale hereunder may be conducted by an
auctioneer or any officer or agent of Lender.

                  (b) If, at the original  time or times  appointed for the sale
of the whole or any part of the Pledged Collateral, the highest bid, if there be
but  one  sale,  shall  be  inadequate  to  discharge  in full  all the  Secured
Obligations, or if the Pledged Collateral be offered for sale in lots, if at any
of such sales,  the  highest bid for the lot offered for sale would  indicate to
Lender, in its discretion,  the unlikelihood of the proceeds of the sales of the
whole of the Pledged  Collateral  being  sufficient to discharge all the Secured
Obligations,  Lender  may,  on  one or  more  occasions  and in its  discretion,
postpone  any of said  sales by public  announcement  at the time of sale or the
time of previous  postponement of sale, and no other notice of such postponement
or  postponements  of sale need be given,  any other notice being hereby waived;
provided,  however, that any sale or sales made after such postponement shall be
after seven (7) days' notice to Pledgors.

                  (c) In the event of any sales  hereunder  Lender shall,  after
deducting all costs or expenses of every kind (including  reasonable  attorneys'
fees and disbursements) for care,  safekeeping,  collection,  sale,  delivery or
otherwise,  apply the  residue of the  proceeds  of the sales to the  payment or
reduction,  either in whole or in part, of the Secured Obligations in accordance
with the agreements and instruments  governing and evidencing such  Obligations,
returning the surplus, if any, to Pledgors.

                  (d) If, at any time when Lender  shall  determine  to exercise
its right to sell the  whole or any part of the  Pledged  Collateral  hereunder,
such Pledged Collateral or the part thereof to be sold shall not, for any reason
whatsoever,  be  effectively  registered  under the  Securities  Act of 1933, as
amended (or any similar statute then in effect) (the "Act"),  Lender may, in its
discretion  (subject only to applicable  requirements of law), sell such Pledged
Collateral  or part  thereof  by  private  sale in such  manner  and under  such
circumstances  as Lender may deem  necessary  or  advisable,  but subject to the
other  requirements  of this Section 8, and shall not be required to effect such
registration  or  to  cause  the  same  to be  effected.  Without  limiting  the
generality of the foregoing, in any such event Lender in its discretion (x) may,
in accordance with applicable securities laws, proceed to make such private sale
notwithstanding  that a  registration  statement for the purpose of  registering
such Pledged  Collateral or part thereof could be or shall have been filed under



                                       11



<PAGE>



the Act, (y) may  approach and  negotiate  with a single  possible  purchaser to
effect  such  sale  and (z) may  restrict  such  sale to a  purchaser  who  will
represent and agree that such purchaser is purchasing  for its own account,  for
investment  and not  with a view  to the  distribution  or sale of such  Pledged
Collateral or part thereof.  In addition to a private sale as provided  above in
this  Section  8,  if  any  of  the  Pledged  Collateral  shall  not  be  freely
distributable  to the public without  registration  under the Act at the time of
any proposed  sale pursuant to this Section 8, then Lender shall not be required
to  effect  such  registration  or cause  the same to be  effected  but,  in its
discretion  (subject only to applicable  requirements  of law), may require that
any sale  hereunder  (including  a sale at  auction)  be  conducted  subject  to
restrictions  (i) as to the financial  sophistication  and ability of any Person
permitted to bid or purchase at any such sale, (ii) as to the content of legends
to be placed upon any certificates  representing the Pledged  Collateral sold in
such sale,  including  restrictions on future transfer thereof,  (iii) as to the
representations required to be made by each Person bidding or purchasing at such
sale relating to that Person's  access to financial  information  about Pledgors
and such Person's intentions as to the holding of the Pledged Collateral so sold
for  investment,  for its own account,  and not with a view to the  distribution
thereof,  and (iv) as to such other  matters as Lender may,  in its  discretion,
deem  necessary  or  appropriate  in order that such sale  (notwithstanding  any
failure so to register) may be effected in compliance  with the Bankruptcy  Code
and other laws affecting the  enforcement  of creditors'  rights and the Act and
all applicable state securities laws.

                  (e) Each  Pledgor  recognizes  that any such  private sale may
result in prices and other terms less  favorable to the seller than if such sale
were a public sale and, notwithstanding such circumstances, agrees that any such
private  sale  shall be deemed to have  been made in a  commercially  reasonable
manner.  Lender  shall  be  under  no  obligation  to delay a sale of any of the
Pledged Collateral for the period of time necessary to permit the  registrant to
register  such  securities  for public sale under the Act,  or under  applicable
state securities laws, even if any Pledgor would agree to do so.

                  (f) Each Pledgor  agrees that  following  the  occurrence  and
during the  continuance  of an Event of  Default it will not at any time  plead,
claim  or  take  the  benefit  of any  appraisal,  valuation,  stay,  extension,
moratorium  or  redemption  law now or hereafter in force in order to prevent or
delay the  enforcement of this  Agreement,  or the absolute sale of the whole or
any part of the Pledged Collateral or the possession thereof by any purchaser at
any sale hereunder,  and each Pledgor waives the benefit of all such laws to the
extent it lawfully  may do so. Each  Pledgor  agrees that it will not  interfere
with any right, power and remedy of Lender provided for in this Agreement or now
or  hereafter  existing at law or in equity or by statute or  otherwise,  or the



                                       12



<PAGE>



exercise  or  beginning  of the  exercise  by  Lender of any one or more of such
rights,  powers  or  remedies.  No  failure  or delay on the part of  Lender  to
exercise  any such right,  power or remedy and no notice or demand  which may be
given to or made upon any  Pledgor by Lender with  respect to any such  remedies
shall operate as a waiver thereof, or limit or impair Lender's right to take any
action or to exercise any power or remedy  hereunder,  without notice or demand,
or prejudice its rights as against any Pledgor in any respect.

                  (g) Each  Pledgor  further  agrees that a breach of any of the
covenants  contained in this Section 8 will cause irreparable  injury to Lender,
that  Lender has no  adequate  remedy at law in respect of such breach and, as a
consequence,  agrees that each and every  covenant  contained  in this Section 8
shall be specifically  enforceable against such Pledgor, and such Pledgor hereby
waives  and agrees not to assert  any  defenses  against an action for  specific
performance of such covenants except for a defense that the Secured  Obligations
are not then due and payable in accordance  with the agreements and  instruments
governing and evidencing such obligations.

                  9. Application of Proceeds. Any cash held by Lender as Pledged
Collateral  and all cash proceeds  received by Lender in respect of any sale of,
liquidation  of,  or  other  realization  upon  all or any  part of the  Pledged
Collateral  or  pursuant to Section  8(g)  hereof  shall be applied by Lender as
follows:

                  (a) First,  to the  payment of the costs and  expenses of such
sale,  including  reasonable  compensation to Lender and its agents and counsel,
and all  expenses,  liabilities  and  advances  made or  incurred  by  Lender in
connection therewith;

                  (b)      Next, to the payment of the Secured Obligations; and

                  (c) Finally, after payment in full of all Secured Obligations,
to the payment to Pledgors, or their successors or assigns, or to whomsoever may
be lawfully entitled to receive the same or as a court of competent jurisdiction
may direct, of any surplus then remaining from such proceeds.

                  10. Waiver.  No delay on Lender's part in exercising any power
of sale, Lien,  option or other right  hereunder,  and no notice or demand which
may be given to or made upon  Pledgors  by Lender  with  respect to any power of
sale, Lien, option or other right hereunder,  shall constitute a waiver thereof,
or limit or impair Lender's right to take any action or to exercise any power of
sale, Lien,  option, or any other right hereunder,  without notice or demand, or
prejudice Lender's rights as against Pledgors in any respect.



                                       13



<PAGE>



                  11.  Assignment.  Lender may assign,  endorse or transfer  any
instrument evidencing all or any part of the Secured Obligations as provided in,
and in accordance  with, the Note, the Keep Well, the Keep Well Guaranty and the
Loan  Guaranty,  as  applicable,  and the  holder  of such  instrument  shall be
entitled to the benefits of this Agreement.

                  12.  Termination.  Immediately  following  the  payment of all
Secured Obligations, Lender shall deliver to each Pledgor the Pledged Collateral
pledged  by  such  Pledgor  at the  time  subject  to  this  Agreement  and  all
instruments of assignment  executed in connection  therewith,  free and clear of
the Liens hereof and,  except as  otherwise  provided  herein,  all of Pledgors'
obligations hereunder shall at such time terminate.

                  13. Lien  Absolute.  All rights of Lender  hereunder,  and all
obligations  of  Pledgors   hereunder,   shall  be  absolute  and  unconditional
irrespective of:

                  (a) any lack of validity or  enforceability  of the Note,  the
Purchase Agreement,  the Keep Well, the Keep Well Guaranty, the Loan Guaranty or
any  other   agreement  or  instrument   governing  or  evidencing  any  Secured
Obligations;

                  (b) any change in the time,  manner or place of payment of, or
in any other term of, all or any part of the Secured  Obligations,  or any other
amendment or waiver of or any consent to any departure  from the Note,  the Keep
Well,  the Keep Well  Guaranty,  the Loan  Guaranty  or any other  agreement  or
instrument governing or evidencing any Secured Obligations;

                  (c)  any  exchange,  release  or  nonperfection  of any  other
collateral,  or any release or  amendment  or waiver of or consent to  departure
from any guaranty, for all or any of the Secured Obligations; or

                  (d) any other circumstance which might otherwise  constitute a
defense available to, or a discharge of, any Pledgor.

                  14. Release.  Each Pledgor consents and agrees that Lender may
at any time, or from time to time, in its discretion (a) renew, extend or change
(pursuant to any right to do so provided in the relevant  agreement) the time of
payment,  and/or the manner, place or terms of payment of all or any part of the
Secured Obligations and (b) exchange, release and/or surrender all or any of the
Pledged Collateral,  or any part thereof, by whomsoever deposited,  which is now
or may hereafter be held by Lender in connection  with all or any of the Secured
Obligations;  all in such manner and upon such terms as Lender may deem  proper,



                                       14



<PAGE>



and without  notice to or further  assent  from such  Pledgor,  it being  hereby
agreed  that  such  Pledgor  shall be and  remain  bound  upon  this  Agreement,
irrespective  of the  existence,  value  or  condition  of  any  of the  Pledged
Collateral,   and  notwithstanding  any  such  change,   exchange,   settlement,
compromise,  surrender,  release, renewal or extension, and notwithstanding also
that the Secured  Obligations may, at any time,  exceed the aggregate  principal
amount thereof set forth in the Note, the Keep Well, the Keep Well Guaranty, the
Loan Guaranty or any other  agreement  governing any Secured  Obligations.  Each
Pledgor  hereby  waives  notice  of  acceptance  of  this  Agreement,  and  also
presentment,  demand,  protest  and  notice  of  dishonor  of any and all of the
Secured Obligations,  and promptness in commencing suit against any party hereto
or liable  hereon,  and in giving any notice to or of making any claim or demand
hereunder  upon such  Pledgor.  No act or omission of any kind on Lender's  part
shall in any event affect or impair this Agreement.

                  15. Indemnification. Each Pledgor jointly and severally agrees
to indemnify and hold Lender  harmless from and against any taxes,  liabilities,
claims and damages, including reasonable attorney's fees and disbursements,  and
other  expenses  incurred  or arising by reason of the taking or the  failure to
take action by Lender,  in good faith,  in respect of any  transaction  effected
under  this  Agreement  or in  connection  with the Lien  provided  for  herein,
including, without limitation, any taxes payable in connection with the delivery
or  registration  of any of the  Pledged  Collateral  as provided  herein.  Each
Pledgor jointly and severally agrees to promptly reimburse Lender for all actual
reasonable  out-of-pocket  costs and expenses,  including,  without  limitation,
reasonable   counsel  fees,   incurred  by  Lender,   in  connection   with  the
administration  and  enforcement  of this  Agreement  and all  reasonable  fees,
expenses and disbursements,  including the reasonable fees of Lender's agents or
representatives,  incurred in connection with any lien searches and filings made
by Lender, any amendments hereto or waivers or modifications  hereof;  provided,
however,  that  Pledgors  shall not be  obligated  to pay any costs or  expenses
(including attorney's fees) incurred by Lender in connection with preparation of
this Agreement or any other Ancillary  Agreement or any ordinary  administrative
costs and expenses of Lender in the absence of a Default by Borrower  under this
Agreement, the Note or any other Ancillary Agreement or a Default by any Pledgor
under this Agreement or any other Ancillary  Agreement;  and provided,  further,
that  nothing  contained  herein  shall limit or be deemed to limit any right of
Borrower under Section 13 of the Purchase Agreement. The obligations of Pledgors
under this Section 15 shall survive the termination of this Agreement.

                  16.  Reinstatement.  This Agreement shall remain in full force
and effect and  continue  to be  effective  should any  petition  be filed by or
against any Pledgor for liquidation or reorganization, should any Pledgor become



                                       15



<PAGE>



insolvent  or make an  assignment  for the  benefit  of  creditors  or  should a
receiver  or  trustee  be  appointed  for  all or any  significant  part  of any
Pledgor's  assets,  and shall continue to be effective or be reinstated,  as the
case may be, if at any time payment and performance of the Secured  Obligations,
or any part thereof,  is,  pursuant to applicable  law,  rescinded or reduced in
amount,  or must otherwise be restored or returned by any obligee of the Secured
Obligations,  whether as a "voidable  preference,"  "fraudulent  conveyance," or
otherwise,  all as though such payment or performance  had not been made. In the
event that any payment, or any part thereof, is rescinded,  reduced, restored or
returned, the Secured Obligations shall be reinstated and deemed reduced only by
such amount paid and not so rescinded, reduced, restored or returned.

                  17.  Miscellaneous.  (a) Lender may  execute any of its duties
hereunder by or through  agents or employees  and shall be entitled to advice of
counsel concerning all matters pertaining to its duties hereunder.

                  (b)  Neither  Lender  nor  any  of  its  officers,  directors,
employees,  agents or counsel shall be liable for any action  lawfully  taken or
omitted to be taken by it or them  hereunder or in connection  herewith,  except
for its or their own gross negligence or willful misconduct.

                  (c) This  Agreement  shall be binding upon  Pledgors and their
successors  and assigns,  and shall inure to the benefit of, and be  enforceable
by,  Lender  and its  successor  and  assigns,  and shall be  governed  by,  and
construed  and enforced in accordance  with,  the internal laws in effect in the
State of  California  without  giving effect to principles of conflicts of laws,
and none of the terms or  provisions of this  Agreement may be waived,  altered,
modified  or amended  except in writing  duly signed for and on behalf of Lender
and Pledgors.

                  18.   Severability.   If  for  any  reason  any  provision  or
provisions  hereof are  determined to be invalid and contrary to any existing or
future law,  such  invalidity  shall not impair the operation of or affect those
portions of this Agreement which are valid.

                  19. Notices.  Except as otherwise provided herein, whenever it
is  provided  herein  that  any  notice,  demand,  request,  consent,  approval,
declaration or other  communication  shall or may be given to or served upon any
of the parties by any other  party,  or whenever  any of the parties  desires to
give or serve upon any other a  communication  with  respect to this  Agreement,

                  20.   Confidentiality.   Lender   agrees  that  it  will  keep

connection with the transactions  contemplated hereunder and agrees that it will
only use such  information  in connection  with such  transactions  and will not
disclose  any of such  information  other than (i) to its  directors,  officers,
employees, advisors, auditors, agents or representatives who are or are expected
to be involved in the  evaluation of such  information  in connection  with such
transactions and who are advised of the confidential  nature of such information
(and for whose  compliance  Lender  shall be  liable),  (ii) to the extent  such
information  presently  is  or  hereafter  becomes  available  to  Lender  on  a
non-confidential  basis from a source other than a Pledgor,  (iii) to the extent
such information has been independently  acquired or developed by Lender without
violating any of its obligations under the Purchase Agreement  or any  Ancillar
Agreement or (iv) to the extent  disclosure  is required by law,  regulation  or
judicial order.

                  21.  Section  Titles.  The Section  titles  contained  in this

                  22. Counterparts. This Agreement may be executed in any number
of  counterparts,  which shall,  collectively  and  separately,  constitute  one
agreement.

                  23. Limited Recourse. Notwithstanding anything to the contrary
contained  herein,  in the Ancillary  Agreements,  the Keep Well,  the Keep Well
Guaranty,  the Loan Guaranty or any other  document or  instrument  executed and
delivered in connection with the consummation of the  transactions  contemplated
hereby and  thereby  (the "Loan  Documents"),  none of Rosemont  Leasing,  Inc.,
Edward P.  Schneider,  Steven C.  Wight and John E. Flynn  shall  have  personal
liability  for  the  payment  or  performance  of the  Obligations  or  for  the
representations,  warranties or covenants  contained in the Loan Documents,  and

Lender and each  transferee,  holder or  assignee of all or any part of the Loan
Documents agree not to seek any damages or personal money judgement  against any
of Rosemont Leasing, Inc., Edward P. Schneider, Steven C. Wight or John E. Flynn
for any default under any or all of the Loan  Documents,  but in any such event,
will look solely to the Pledged Collateral. Nothing herein or in any of the Loan
Documents  shall be construed to prevent Lender and each  transferee,  holder or
assignee of any such Loan  Document  from  exercising  and  enforcing  any other
remedy (not  involving  personal  liability)  allowed at law or equity or by any
statute. The foregoing  exculpation shall not limit or be construed to limit the
personal liability of any Rosemont Leasing, Inc., Edward P. Schneider, Steven C.
Wight or John E. Flynn to the extent  that after a default  shall have  occurred
under one or more of the Loan Documents, any thereof shall collect rents, issues
or profits of any of the property  secured by the Loan  Documents  and shall not
promptly  apply  the  same in the  manner  required  or  permitted  by the  Loan
Documents,  it being intended that Rosemont Leasing,  Inc., Edward P. Schneider,
Steven C. Wight and John E. Flynn shall be personally  liable to the full extent
of such misapplication after a default.

                                    EXHIBIT A

                    Agreement,  dated  April  2,  1997,  by and  among  Rosemont
Leasing, Inc., Edward P. Schneider,  Steven C. Wight and John E. Flynn regarding
mutual options on the Pledged Interests.



                               KEEP WELL AGREEMENT


                  This KEEP WELL  AGREEMENT  is dated as of April 1,  1997,  and
made by TRITON AVIATION SERVICES LIMITED,  a Bermuda  corporation  ("TASL"),  in
favor of TRITON AVIATION SERVICES V LLC, a California  limited liability company
(the  "Borrower"),  and in favor of POLARIS AIRCRAFT INCOME FUND V, a California
limited partnership (the "Lender") (the "Agreement").

                                R E C I T A L S:

                  WHEREAS,  the Lender has entered  into a Purchase,  Assignment
and  Assumption  Agreement  dated as of April 1,  1997 with the  Borrower  (said
Agreement,  as it may  hereafter be amended or otherwise  modified  from time to
time,  being  the  "Purchase  Agreement",  the  terms  defined  therein  and not
otherwise  defined  herein  being  used  herein  as  therein  defined)  and,  in
connection therewith, the Borrower has delivered to the Lender a promissory note
effective as of April 1, 1997 in the amount of $40,984,460 (the "Note"); and

                  WHEREAS,  TASL, as the owner of 99 percent of the  outstanding
member interests in the Borrower,  will derive  substantial  direct and indirect
economic  benefit from the transactions  contemplated by the Purchase  Agreement
and the delivery of the Note to the Lender; and

                  WHEREAS,  in connection with the execution and delivery of the
Purchase  Agreement and the Note,  the Lender is requiring  that TASL shall have
executed and delivered this Agreement;

                  NOW, THEREFORE,  in consideration of the premises and in order
to induce the Lender to enter into the Purchase Agreement and accept delivery of
the Note, TASL hereby agrees as follows:


SECTION 1.  Obligation  to Cause the Borrower to Perform.  (a) TASL shall pay to
the  Borrower  from  time to time,  in cash in  United  States  dollars  through
additional  contributions to the equity of the Borrower,  amounts  sufficient to
permit the Borrower  promptly to perform all of its obligations  under the Note,
the Security Agreement and the Purchase Agreement.









<PAGE>









                  (b) Notwithstanding anything to the contrary contained herein,
TASL shall not be required to make  unrecouped  payments under this Agreement to
the Borrower or the Lender in excess of an aggregate of $4,034,060 (the "Maximum
Obligation") at any time outstanding;  provided,  however, that any dividends or
other  distributions made by the Borrower (other than dividends or distributions
made in respect of any Equity  Dividend  Amount,  as such term is defined in the
Note),  shall be deemed to be made in  recoupment  of any payments  made by TASL
hereunder and the aggregate  amount of TASL's  obligation  under  subsection (a)
above shall be restored by the amount of such  dividend or  distribution,  up to
the Maximum Obligation.

                  (c) If TASL  shall at any time and from  time to time  fail to
perform or comply with any of its obligations  contained in subsection (a) above
and if for any  reason  the Lender  shall  have  failed to receive  when due and
payable (whether at stated maturity, by acceleration,  or otherwise) the payment
of all or any part of the  principal  of or  interest  on the Note or any  other
amount payable by the Borrower thereunder or under the Security Agreement or the
Purchase Agreement, then in each such case:

                       (i) it shall be conclusively assumed without necessity of
         proof that such  failure  by TASL was the sole and direct  cause of the
         Lender  failing to receive such payment  when due  irrespective  of any
         other contributing or intervening cause whatsoever;

                       (ii) TASL agrees that it will be  unconditionally  liable
         to the Lender for liquidated  damages (for loss of a bargain and not as
         a penalty)  for the amount of such  payment not  received by the Lender
         when so due and payable as well as for all costs and expenses,  if any,
         incurred by the Lender in  enforcing  this  Agreement  (but only to the
         extent of and as a reduction of the Maximum Obligation);

                       (iii) TASL further  irrevocably waives to the full extent
         permitted by applicable law any right or defense TASL may have to cause
         the Lender to prove the cause or amount of such  damages or to mitigate
         the same; and

                       (iv) since TASL has agreed to  liquidated  damages in the
         amount specified above, the Lender shall not be entitled to any damages
         in excess of such amount with respect to such payment.

                  (d)  Notwithstanding  anything herein to the contrary,  during
any period in which the Lender shall have failed to receive when due and payable




                                        2




<PAGE>









(whether at stated maturity, by acceleration or otherwise) the payment of all or
any part of the principal of or interest on the Note or any other amount payable
by the  Borrower  thereunder  or under the  Security  Agreement  or the Purchase
Agreement, TASL shall make payment of all funds under this Agreement directly to
the Lender c/o Polaris Investment  Management  Corporation,  201 Mission Street,
27th Floor,  San Francisco,  CA 94105,  and the Lender shall apply such funds in
the same manner as though paid directly by the Borrower.  All payments which are
received by the Borrower contrary to the provisions of this subsection (d) shall
be received in trust for the benefit of the  Lender,  shall be  segregated  from
other funds and  property  held by the  Borrower,  and shall be paid over to the
Lender in the same form as so received (with any necessary indorsement).

                  SECTION 2. Other Permitted Payments. If and to the extent that
amounts paid to the Borrower  pursuant to Section 1(a) do not exceed the Maximum
Obligation,  TASL may make  payments to the  Borrower  from time to time for any
purpose in which the  Borrower  is  permitted  to  engage,  and in each case the
amount of such  payment  shall be credited  against  TASL's  obligation  to make
payments to the Borrower under Section 1(a) hereof up to the Maximum Obligation;
provided,  however, that if the Borrower sells, transfers,  conveys or otherwise
disposes  of an Asset (as such term is defined  in the Note) for an amount  (the
"Sale Price") that is less than 90% of the product of (x) the Allocable  Portion
Percentage  (as defined in the Note) for such Asset  multiplied  by (y) the then
outstanding  balance of the Note,  then any payment made by TASL to the Borrower
in the 60 day  period  preceding  or the  60 day  period  following  such  sale,
transfer,  conveyance or other  disposition  shall be included in determining if
the Maximum  Obligation has been reached only after  deducting (a) the Shortfall
Amount (as defined  below) and (b) any dividends or other  distributions  (other
than dividends or  distributions  in respect of any Equity Dividend Amount) made
by the  Borrower  during both such  periods.  For  purposes  of this  Section 2,
"Shortfall  Amount"  means the amount  that is the  difference  between  (i) the
product of the Allocable  Portion  Percentage for the Asset which has been sold,
transferred,   conveyed  or  otherwise   disposed  of  multiplied  by  the  then
outstanding balance of the Note and (ii) the Sale Price.

                  SECTION 3. Taxes,  Authorizations,  Etc. (a) TASL will pay any
stamp or other tax (including  any interest and  penalties)  with respect to the
performance by TASL of its  obligations  pursuant to this  Agreement;  provided,
however, in no event shall such taxes include any taxes imposed upon or measured
by the gross or net income of the  Borrower  or the  Lender.  If any such tax is
paid by the Lender in the good faith  belief that such tax is owing,  TASL will,
upon demand of the Lender, indemnify the Lender for such payment,  together with




                                        3




<PAGE>









any  interest,  penalties  and expenses in  connection  therewith  plus interest
thereon  at the lesser of 10% or the  maximum  rate under  applicable  law.  The
Lender shall thereafter cooperate in a commercially  reasonable manner with TASL
in seeking any refunds of such taxes,  interest,  penalties  and expenses  which
refunds and any interest thereon shall be paid by the Lender to TASL within five
(5) business days of receipt by the Lender, provided, that in no event shall the
Lender be  required  to expend  its own funds in  seeking  any such  refund  and
provided,  further,  that any expenses incurred in connection therewith shall be
paid by TASL.

                  (b) TASL will  obtain  any  authorization,  approval  or other
action by, and will give any notice to or make any filing with, any governmental
authority or regulatory body required in connection with the performance by TASL
of its obligations pursuant to this Agreement.

                  SECTION  4.  Obligation   Absolute.   TASL  will  perform  its
obligations under this Agreement  regardless of any law, regulation or order now
or hereafter  in effect in any  jurisdiction  affecting  any of the terms of the
Note,  the Security  Agreement or the Purchase  Agreement or any other  document
related  thereto  or  the  rights  of  the  Lender  with  respect  thereto.  The
obligations  of TASL under this  Agreement  shall be absolute and  unconditional
irrespective of:

                       (i) any lack of validity,  enforceability or value of the
         Purchase  Agreement,  the Note,  the  Security  Agreement  or any other
         agreement or instrument relating thereto or any collateral therefor;

                       (ii) any  change in any term of the Note  (including  any
         change in the time, manner or place of payment  thereof),  the Security
         Agreement or the Purchase  Agreement,  or any other amendment or waiver
         of or any consent to departure from the Note, the Security Agreement or
         the Purchase Agreement;

                       (iii) any  exchange,  release  or  non-perfection  of any
         collateral,  or any  release  or  amendment  or waiver of or consent to
         departure from any guaranty,  for the Note,  the Security  Agreement or
         the Purchase Agreement;

                       (iv) any  failure  to pay any taxes  which may be payable
         with respect to the  performance  of such  obligations  by TASL, or any
         failure to obtain any  authorization  or approval  from or other action
         by,  or to notify or file  with,  any  Government  Entity  required  in
         connection with the performance of such obligations by TASL; or



                                        4




<PAGE>









                       (v) any  impossibility or  impracticality of performance,
         illegality,  force majeure,  any act of any Government  Entity,  or any
         other  circumstance which might constitute a defense available to, or a
         discharge  of, TASL or a surety,  or any other  circumstance,  event or
         happening  whatsoever,  whether  foreseen  or  unforeseen  and  whether
         similar or dissimilar to anything referred to above in this Section 4.

This Agreement shall continue to be effective or be reinstated,  as the case may
be, if at any time any payment is rescinded or must otherwise be returned by the
Lender upon the  insolvency,  bankruptcy  or  reorganization  of the Borrower or
otherwise, all as though such payment had not been made. The obligations of TASL
under this  Agreement  shall not be subject to reduction,  termination  or other
impairment by reason of any set-off, recoupment,  counterclaim or defense or for
any other reason.

                  SECTION 5. Waiver.  TASL hereby waives promptness,  diligence,
notice  of  acceptance  and  any  other  notice  with  respect  to the  Purchase
Agreement,  the Note and this  Agreement  and any  requirement  that the  Lender
protect, secure, perfect or insure any security interest or lien or any property
subject  thereto or exhaust any right or take any action against the Borrower or
any other person or entity or any collateral.

                  SECTION  6.  Separate   Undertaking.   Without   limiting  the
generality  of  any  of  the  foregoing  provisions  of  this  Agreement,   TASL
irrevocably  waives,  to the full extent permitted by applicable law and for the
benefit of, and as a separate  undertaking with, the Lender,  any defense to the
performance of this Agreement which may be available to TASL as a consequence of
this  Agreement  being  rejected or otherwise not assumed by the Borrower or any
trustee or other similar  official for the Borrower or for any substantial  part
of the property of the Borrower,  or as a consequence  of this  Agreement  being
otherwise  terminated or modified,  in any proceeding  seeking to adjudicate the
Borrower  a  bankrupt  or   insolvent  or  seeking   liquidation,   winding  up,
reorganization,  arrangement,  protection, relief or composition of the Borrower
or the debts of the Borrower under any law relating to bankruptcy, insolvency or
reorganization  or relief or  protection  of debtors,  whether  such  rejection,
non-assumption, termination or modification be by reason of this Agreement being

                                        5

standing  under the laws of each  jurisdiction  where its  ownership or lease of
property or the conduct of its business requires such qualification  (except for
jurisdictions  in which failure to so qualify or be in good  standing  would not
have a material adverse effect on the business, assets,  operations,  prospects,
or financial or other condition of Borrower (a "Material Adverse Effect")).

                  2.2. The  execution,  delivery and  performance by Borrower of
this Promissory Note are within  Borrower's  power, have been duly authorized by
all  necessary  or  proper  limited  liability   company  action,   are  not  in
contravention of any provision of Borrower's articles of organization, operating
agreement,  or any other such  governing  document,  will not violate any law or
regulation,  or any order or decree of any Government Entity,  will not conflict
with or result in the breach or  termination  of,  constitute a default under or
accelerate any performance required by, any indenture,  mortgage, deed of trust,
lease,  agreement,  or other instrument to which Borrower is a party or by which
Borrower or its property is bound, and do not require the consent or approval of
any Person except those already  obtained.  This Promissory Note constitutes the
legal,  valid and  binding  obligation  of  Borrower  enforceable  against it in
accordance  with its terms,  subject to the  effect of  bankruptcy,  insolvency,
reorganization,  receivership,  moratorium  and other similar laws affecting the
rights  and  remedies  of  creditors   generally   and,   with  respect  to  the
enforceability  of this  Promissory  Note,  by  general  principles  of  equity,
including principles of commercial  reasonableness,  good faith and fair dealing
(regardless  of  whether  enforcement  is  sought in a  proceeding  at law or in
equity).

                  2.3.  The pro forma  balance  sheet of  Borrower  as of May 1,
1997, a copy of which has been  furnished to Lender,  was prepared in accordance
with  generally  accepted  accounting   principles  ("GAAP")  and  reflects  the
assignment of all Transferred  Interests and the seller  financing  transactions
contemplated  hereunder and under the Purchase Agreement as if they had occurred
as at the date of such balance  sheet and  presents  fairly on a pro forma basis
the financial position of Borrower at such date assuming the events specified in
this paragraph had actually occurred on such date.  Borrower,  as of the date of
this Promissory Note, had no obligations,  contingent liabilities or liabilities
for taxes or other  charges,  long-term  leases or unusual  forward or long-term
commitments  which were not  reflected in the  aforementioned  pro forma balance
sheet of Borrower.

                  2.4. No dividends or other  distributions  have been declared,
paid or made upon any  membership  interest  (or any other  equity  interest) of
Borrower nor have any  membership  interests  (or any other equity  interest) of
Borrower been redeemed,  retired,  purchased or otherwise  acquired for value by
Borrower.

                  2.5. Borrower owns full, complete and good title to all of its
properties  and assets and none of its  properties  and assets is subject to any
mortgage  or  deed  of  trust,  pledge,   hypothecation,   assignment,   deposit
arrangement, lien, charge, claim, security interest, easement or encumbrance, or
other security agreement of any kind or nature whatsoever (collectively, "Liens"
and  individually,  a "Lien"),  except  Permitted  Encumbrances  (as  defined in
Section 4.3 hereof).

                  2.6.  Borrower has insurance on all its  properties or assets,
including,  without  limitation,  policies of fire, theft and other casualty and
liability  insurance on terms and  conditions  and in amounts that are customary
for  owners of  commercial  aircraft.  All such  policies  are in full force and
effect and there are no defaults by any party under any provision thereof.

                  2.7.  Borrower  is not in  default,  nor is any third party in
default,  under  or with  respect  to any  contract,  agreement,  lease or other
instrument to which Borrower is a party.

                  2.8. Borrower is not an "investment company" or an "affiliated
person"  of, or  "promoter"  or  "principal  underwriter"  for,  an  "investment
company," as such terms are defined in the  Investment  Company Act of 1940,  as
amended.  The  obligations  evidenced by this  Promissory  Note,  the  repayment
thereof and the consummation of the transactions contemplated by this Promissory
Note will not violate any provision of such Act or any rule, regulation or order
issued by the Securities and Exchange Commission thereunder.

                  2.9. The seller  financing  evidenced by this  Promissory Note
will be used only for the purposes contemplated hereunder and under the Purchase
Agreement.

                  2.10.  All  federal,  state,  local and foreign  tax  returns,
reports and statements required to be filed by Borrower have been filed with the
appropriate  governmental  agencies and all taxes, charges and other impositions
shown  thereon to be due and  payable  have been paid prior to the date on which
any fine,  penalty,  interest or late charge may be added thereto for nonpayment
thereof,  or any such  fine,  penalty,  interest  or late  charge has been paid.
Borrower has paid when due and payable all taxes and other  charges  required to
be paid by it except those  contested in good faith by appropriate  proceedings,
with  adequate  reserves made in respect  thereof in accordance  with and to the
extent required by GAAP.

                  2.12.  No  action,  claim  or  proceeding  is now  pending  or
threatened against Borrower,  at law, in equity or otherwise,  before any court,
board,  commission,  agency or instrumentality  of any federal,  state, or local
government or of any agency or subdivision  thereof, or before any arbitrator or
panel of arbitrators nor does a state of facts exist which is reasonably  likely
to give rise to such proceedings.

                  2.13. All  representations  and warranties made by Borrower in
the Purchase  Agreement are true and correct in all material  respects on and as
of the date hereof as though made on and as of this date.

                  3.5.  Borrower shall deliver to Lender such other  information
respecting Borrower's business,  financial condition or prospects as Lender may,
from time to time,  reasonably request including,  without  limitation,  monthly
reports  of the  outstanding  balances  of  accounts  receivable  since the last
monthly  report;  a detailed  aged trial balance of all  then-existing  accounts
receivable by Lessee and specifying the names of account  debtors and such other
information  relating  to the  accounts  receivable  as  Lender  may  reasonably
require;  and a certificate  of the gross revenues of Borrower for the preceding
month.  Lender and any of its officers,  employees  and/or agents shall have the
right,   exercisable  as  frequently  as  Lender  reasonably  determines  to  be
appropriate,  during  normal  business  hours  (or at such  other  times  as may
reasonably be requested by Lender),  to inspect the properties and facilities of
Borrower and to inspect, audit and make extracts from all of Borrower's records,
files and books of account.  Borrower  shall  deliver any document or instrument
reasonably  necessary  for  Lender to obtain  records  from any  service  bureau

                  3.6.  (a)  Borrower  shall,  either  directly  or  indirectly,
procure and maintain insurance policies with reputable insurers, covering all of
its properties or assets, including, without limitation, policies of fire, theft
and other  casualty  and  liability  insurance on terms and  conditions  and for
amounts that are customary for owners of commercial  aircraft.  Without limiting
the foregoing, Borrower shall, directly or indirectly,  procure and maintain, at
all times,  (i) all risk hull  insurance  (including  the War and Allied  Perils
Endorsement  insurance) written by recognized aircraft insurers on each Aircraft
owned, directly or indirectly,  by Borrower in an amount equal, at all times, to
the Appraised Value of such Aircraft and (ii) comprehensive  liability insurance
written in an amount  not less than  $500,000,000.  Lender  shall be named as an
additional  insured  on all such  insurance  policies  and  named as  additional
insured on all liability policies.

                  (b) All such policies of insurance  shall provide (i) by means
of endorsements or otherwise,  in form and manner  satisfactory to Lender,  that
such  insurance  shall not be  invalidated by any action or inaction of Borrower
and shall insure Lender,  regardless of any breach or violation of any warranty,
declaration or condition  contained in such policies by Borrower;  (ii) by means
of endorsements or otherwise in form and manner  satisfactory to Lender, that if
such insurance is cancelled for any reason whatever,  or any substantial  change






                                       10



<PAGE>







is made in the  coverage  which  affects  the  interests  of  Lender  or if such
insurance  is allowed to lapse for  nonpayment  of premium,  such  cancellation,
change or lapse shall not be effective as to Lender for 30 days (or, in the case
of any war risks or allied perils coverage, seven (7) days, or such other period
as may  from  time to time be  customarily  obtainable  in the  industry)  after
receipt by Lender of written  notice from such  insurers  of such  cancellation,
change or lapse;  (iii) by means of endorsements or otherwise in form and manner
satisfactory to Lender, that such insurers shall waive any rights of subrogation
against Lender;  (iv) that they are primary  without right of contribution  from
any other insurance which is carried by Lender with respect to any Aircraft that
is owned,  directly or  indirectly,  by Borrower  (or any engines or other parts
thereof);  and (v) that all provisions thereof,  except the limits of liability,
shall  operate in the same  manner as if there were a separate  policy  with and
covering each insured.

                  (c) Borrower shall arrange for appropriate  certification,  to
the  reasonable  satisfaction  of Lender,  as to the scope and existence of such
insurance  and the  terms  thereof  to be  made to  Lender  on or  prior  to the
occurrence of the first Effective Time under the Purchase Agreement and annually
thereafter, until this Promissory Note is paid in full, and thereafter not later
than fourteen (14) days after the renewal date of each of the insurances by each
insurer (or by a firm of independent  insurance brokers of reorganized  standing
in the placement of similar coverage) in such form and dealing with such matters
relating to the  obligations  of  Borrower  hereunder  as Lender may  reasonably
require.

                  3.7.  Borrower shall comply with all Federal,  state and local
laws and regulations  applicable to it,  including,  without  limitation,  those
relating to environmental matters and perform, within all required time periods,
all of its  obligations  and enforce all of its rights  under each  agreement to
which it is a party.  Borrower  shall not  terminate  or  modify  in any  manner
materially  adverse to Borrower any  provision of any agreement to which it is a
party.

                  3.8. (a) Borrower  shall make a prepayment on this  Promissory
Note on the terms  hereinafter  set  forth in the event of any sale or  casualty
loss (each a  "Prepayment  Event")  relating  to any  Aircraft  or any  property
comprising all or any portion of any Transferred  Interest  acquired by Borrower
pursuant to the Purchase  Agreement  (an  "Asset")  (each such Asset that is the
subject of a Prepayment Event is hereinafter  referred to as a "Removed Asset");
provided,  however,  a  Prepayment  Event shall not be deemed to include (i) any
sale of an engine or a part if,  within 45 days (with  respect to engines) or 90
days (with respect to parts) after such sale, Borrower obtains a replacement for
such  engine or part that has the same or  greater  value as the  engine or part
that was the subject of such sale,  (ii) any sale of obsolete or surplus  parts,






                                       11



<PAGE>







at their fair market  value,  to the extent that the aggregate of all such sales
in a  calendar  year do not exceed  $200,000  or (iii) any  casualty  loss of an
engine or any part if  Borrower  causes  such  engine or part to be  repaired or
replaced,  within 45 days (with  respect to engines) or 90 days (with respect to
parts) after such casualty  loss,  and such repaired or replaced  engine or part
has the same or greater value as the engine or part that was the subject of such
casualty  loss. If a Prepayment  Event relates to a Removed Asset but relates to
less than the entire Removed Asset,  Borrower and Lender shall negotiate in good
faith to determine the appropriate percentage of such Removed Asset that was the
subject of such Prepayment  Event.  Such percentage  shall then be multiplied by
the appraised value of the entire Removed Asset (calculated immediately prior to
the Prepayment  Event),  and the amount therefrom shall be used to calculate the
Allocable Portion Percentage (as defined below) of the Removed Asset.

                  (b) The  amount of the  prepayment  required  as a result of a
Prepayment  Event  shall be an amount  equal to the  greater  of (1) 100% of the
Allocable  Portion  Percentage  for the  Removed  Asset  multiplied  by the then
outstanding  principal  balance  of this  Promissory  Note and (2) the  proceeds
actually  received  by  Borrower  in respect of the  Removed  Asset,  net of any
reasonable  out of pocket costs and expenses  incurred by Borrower in connection
with such  Prepayment  Event  (but not to exceed an amount  equal to 120% of the
Allocable Portion Percentage with respect to the Removed Asset multiplied by the
then  outstanding  principal  balance of this  Promissory  Note).  The Allocable
Portion Percentage shall mean, with respect to any Asset, the amount obtained by
dividing the appraised  value of the Asset  immediately  prior to the Prepayment
Event by the sum of the  appraised  values  of all  Assets  owned,  directly  or
indirectly,  by Borrower  immediately  prior to the Prepayment  Event.  For this
purpose,  appraised  value of an  Aircraft  owned,  directly or  indirectly,  by
Borrower  shall be the Appraised  Value.  The appraised  value of any receivable
that  constitutes a Removed Asset shall be the aggregate  outstanding  amount of
the principal and accrued interest and fees on such receivable as of the date of
the Prepayment Event.

                  (c) Any prepayment  required as a result of a Prepayment Event
shall be due and payable  hereunder  no later than three (3) days after the date
of the Prepayment Event;  provided,  that if such Prepayment Event is a casualty
loss that is insured, the portion of the prepayment required as a result of such
Prepayment  Event that is payable  pursuant to such insurance  coverage shall be
due and payable hereunder no later than the first to occur of (i) three (3) days
after receipt by Borrower of such  insurance  coverage or (ii) 15 days after the
date of the Prepayment Event. Amounts prepaid pursuant to this Section 3.8 shall
be applied as provided in Section 1.4 hereof.

                  4.2.  (a)  Except as  otherwise  expressly  permitted  by this

reserves on hand adequate to pay such Indebtedness, (iv) deferred taxes that are
either not yet due and  payable or are being  contested  in good faith by proper
legal actions or proceedings,  if Borrower has cash reserves on hand adequate to
pay such deferred taxes, and (v) Indebtedness, not to exceed $26,000,000, in the
aggregate,  during the term of this  Promissory  Note that is incurred  and used
solely to hushkit an Aircraft that is owned, directly or indirectly, by Borrower
(or to refinance  any  Indebtedness  incurred  solely to hushkit such  Aircraft;
provided,  however, that (x) the amount of such Indebtedness does not exceed the
then outstanding  principal  amount of the Indebtedness  being so refinanced and
(y) the term of such  Indebtedness does not materially extend beyond the term of

exceed the aggregate fair market value of such hushkit equipment and labor costs
necessary to install such hushkit equipment on such Aircraft.

                        (b) Borrower shall not make  investments  in, or make or
accrue  loans or  advances of money  through  the direct or indirect  holding of
securities or otherwise to any Person; provided,  however, that Borrower may own
the  Transferred  Interests  and may invest in Permitted  Investments.  Borrower
shall demand  payment  under any Permitted  SPV  Investment  (or any guaranty or
Letter of Credit  guaranteeing or securing such Permitted SPV Investment) to the
extent  Borrower  needs  funds to make any  payments  due to Lender  under  this
Promissory Note.

                  4.3.  Borrower  shall not  create or permit any Lien on any of
its properties or assets except any of the following ("Permitted Encumbrances"):

Aircraft  securing  Indebtedness  of Borrower which is permitted by the terms of
this  Promissory  Note and which is incurred  solely to hushkit such Aircraft (a
"Current  Loan");  provided,  however,  that if such Current Loan constitutes an
extension  of credit  pursuant to an existing  financing  facility of  Borrower,
Borrower  may grant,  to secure such  Current  Loan, a Lien on one or more other
Aircraft  if each such  other  Aircraft  is at such time  subject to a Lien that
secures such existing financing facility,  (D) any renewal or replacement of any
Lien permitted by (C) above (in  connection  with  refinancing  of  Indebtedness
permitted by  subsection  4.2(a)(v)  hereof);  provided,  however,  that (x) the

exceed  the then  outstanding  principal  amount  of the  Indebtedness  being so
refinanced,  (y) such renewal or  replacement  Lien does not spread to cover any
additional  asset  and (z) the  term of the  Indebtedness  secured  by any  such
replacement Lien does not materially  extend beyond the term of the Indebtedness
being so refinanced; (E) leases of the Aircraft and (F) Liens on Aircraft owned,
directly or  indirectly,  by  Borrower of a type that a lessee of such  Aircraft
would  customarily  be  permitted  to incur and be  required to remove from such
Aircraft.

                  4.4.  Borrower  shall  not  issue  or sell or  enter  into any
agreement,  contract or commitment to issue or sell any equity  interest  (other
than those  outstanding as of the date of this Agreement)  unless,  after giving
effect to such  issuance  or sale (a) TASL  shall  remain  the sole  manager  of
Borrower, retaining all responsibilities and duties allocated to TASL as manager
of  Borrower  pursuant to  Borrower's  operating  agreement  or  certificate  of
formation  and shall make no delegation or assignment to any other Person of any
such  responsibility  or duty  except as  permitted  thereby,  (b) the number of
members of Borrower (x) who are not Triton  Members or Triton  Management  shall
not exceed three (3) (y) who are Triton Management shall not exceed five (5) and
(z) who are Triton Members  (excluding TAL, TASL and Triton Container) shall not

pursuant  to the terms of  Section  10  hereof,  Lender  shall  consent  to such
transfer or issuance (such consent not to be unreasonably  withheld);  provided,
however,  that if Lender does not  respond to such  notice  within ten (10) days
after receipt by Lender of such notice,  such consent  shall be deemed  granted.

other  such  governing  document  (other  than  amendments  (1) with  respect to

any other  transaction  with any of its Affiliates,  except (A) any agreement or
transaction  entered into pursuant to the reasonable  requirements of Borrower's

                  4.9.  (a)  Borrower  shall  not  sell,  transfer,   convey  or
otherwise  dispose  of any assets or  properties;  provided,  however,  that the
foregoing  shall not  prohibit  (i)  transfers  resulting  from any  casualty or
condemnation  of assets or  properties or (ii) sales of engines or parts that do
not constitute Prepayment Events pursuant to Section 3.8(a). Notwithstanding the
foregoing,  Borrower may, subject to Section 3.8 hereof, sell Assets without the
consent of the holder of this Promissory Note if the proceeds from any such sale
(net of any costs and  expenses  or other  obligations  incurred  by Borrower in
connection  with  such  sale)  equal or  exceed  100% of the  Allocable  Portion
Percentage  for such Asset  multiplied by the then  outstanding  balance of this
Promissory Note.

                        (b)  Borrower  shall  not  sell,  transfer,   convey  or
otherwise  dispose of all or any  portion of any Asset for an amount (net of any
costs,  expenses or other  obligations  incurred by Borrower in connection  with
such sale, transfer,  conveyance or disposition) less than 100% of the Allocable
Portion  Percentage of such Asset multiplied by the then outstanding  balance of
this  Promissory  Note without the prior  written  consent of the holder of this
Promissory  Note  unless  Borrower  has  sufficient  funds  available  from  (a)
operating cash flow,  exclusive of security  deposits,  maintenance  reserves or
other  property  held by it as  collateral,  (b) the  issuance or sale of equity
interests  in  Borrower,  (c)  sale  proceeds  held by it from the sale of other
Aircraft owned, directly or indirectly by it, (d) funds paid to Borrower by TASL
under  the Keep  Well if the  Asset is  disposed  of for an  amount  equal to or
greater than the product of (1) 90% of the Allocable Portion Percentage for such
Asset multiplied by (2) the then outstanding balance of this Promissory Note, or
(e) any combination of the foregoing, which funds, when added to the proceeds of
the  disposition  of  such  Asset  (net  of any  costs  and  expenses  or  other
obligations  incurred  by  Borrower  in  connection  with such  sale,  transfer,
conveyance or  disposition)  will equal the product of (A) 100% of the Allocable
Portion Percentage of such Asset multiplied by (B) the then outstanding  balance
of this  Promissory  Note. If Borrower  sells,  transfers,  conveys or otherwise
disposes  of  less  than  100%  of  an  Asset,  the  percentage  interest  sold,
transferred,  conveyed  or  otherwise  disposed  of shall be  multiplied  by the
appraised  value of the entire  Asset and the product  thereof  shall be used to
calculate the Allocable Portion Percentage of such Asset for the purposes of the
immediately preceding sentence.

                  4.10. Borrower shall not (A) prepay,  defease,  redeem, retire
or  otherwise  acquire  any  obligation  or  Indebtedness  owed by it  except as

the Equity Dividend Amount and any accrued and unpaid Equity Dividend Amount for
each month thereafter,  (2) amounts equal to equity  contributions made pursuant
to the Keep Well which have not been previously  recouped through the payment of
any dividend or distribution  and (3) amounts equal to any reduction of the Cash
Amount pursuant to Section 4(c) or Section  4(d)(ii) of the Purchase  Agreement;

Promissory Note is overdue or a Default has occurred and is continuing, Borrower
shall not declare,  pay,  incur any liability in respect of or make any dividend
or other distribution whatsoever but Borrower may continue to accrue a liability
equal to the Equity  Dividend  Amount  during such period and  Borrower may make
payments in respect of any such accrued  liability so long as no amounts due and
payable under this  Promissory Note are overdue and no Default is continuing and
provided,  further,  that all dividends or  distributions  by Borrower  shall be
declared,  paid or made only in accordance with applicable law, or (D) incur any

                             GUARANTY (KEEP WELL)


                  GUARANTY,  dated as of April 1,  1997,  of TRITON  INVESTMENTS
LIMITED,  a  Bermuda  corporation  ("Guarantor"),  in favor of  TRITON  AVIATION
SERVICES V LLC, a California limited liability company  ("Borrower") and POLARIS
AIRCRAFT INCOME FUND V, a California limited  partnership  ("Lender")  (Borrower
and Lender each sometimes  referred to herein as a "Beneficiary"  and, together,
as the "Beneficiaries").

                              W I T N E S S E T H:

                  WHEREAS,  Borrower  and Lender have  entered  into a Purchase,
Assignment  and Assumption  Agreement  dated as of April 1, 1997 (as at any time
amended, modified or supplemented,  the "Purchase Agreement") and, in connection
therewith,  Borrower has delivered to Lender a promissory  note  effective as of
April 1, 1997 (the "Note"); and

                  WHEREAS,   Triton  Aviation   Services   Limited,   a  Bermuda
corporation and a majority-owned and controlled subsidiary of Guarantor ("TASL")
is the record and beneficial  owner of 99% of the member  interests in Borrower;
and

                  WHEREAS,  TASL,  Borrower  and Lender have entered into a Keep
Well  Agreement of even date herewith (the "Keep Well"),  pursuant to which TASL
has agreed to pay certain  amounts to Borrower as a  contribution  to Borrower's
equity in order to permit  Borrower  promptly to perform all of its  obligations
under the Note and the Purchase Agreement; and

                  WHEREAS, Guarantor, as the majority owner of TASL, will derive
substantial   direct  and  indirect   economic  benefit  from  the  transactions
contemplated  by the Purchase  Agreement,  the Keep Well and the delivery of the
Note to Lender; and

                  WHEREAS,  in connection with the execution and delivery of the
Purchase  Agreement,  the  Keep  Well  and  the  Note  and as  security  for the
Obligations  (as defined  below),  each of the  Beneficiaries  is requiring that
Guarantor shall have executed and delivered this Guaranty;

<PAGE>



                  NOW,  THEREFORE,  in  consideration  of the  premises  and the
covenants hereinafter contained, and to induce Lender to enter into the Purchase
Agreement, it is agreed as follows:

                  1. DEFINITIONS. Unless otherwise defined herein, terms defined
in the Note are used herein as therein  defined,  and the  following  shall have
(unless otherwise provided elsewhere in this Guaranty) the following  respective
meanings (such meanings being equally applicable to both the singular and plural
form of the terms defined):

                  "Obligations"  means all  obligations  of any kind or  nature,
present or future, of TASL under the Keep Well.

                  References  to  this  "Guaranty"  shall  mean  this  Guaranty,
including all  amendments,  modifications  and  supplements  and any exhibits or
schedules to any of the foregoing,  and shall refer to this Guaranty as the same
may be in effect at the time such reference becomes operative.

                  2.  THE GUARANTY.  The  guaranty of  Guarantor hereunder is as
follows:

                  2.1.  Guaranty  of  Obligations  of  TASL.   Guarantor  hereby
unconditionally  guarantees to each of the  Beneficiaries  and their  respective
successors,  endorsees,  transferees and assigns, the prompt payment (whether at
stated   maturity,   by  acceleration  or  otherwise)  and  performance  of  the
Obligations.  Guarantor  agrees that this  Guaranty is a guaranty of payment and
performance and not of collection,  and that its obligations under this Guaranty
shall be primary,  absolute and  unconditional,  irrespective of, and unaffected
by:

                           (a)   the    genuineness,    validity,    regularity,
         enforceability  or any future amendment of, or change in this Guaranty,
         the Keep Well, the Note or any other agreement,  document or instrument
         to which  Borrower,  TASL,  Lender  and/or  Guarantor  is or are or may
         become a party;

                           (b)  the  absence  of  any  action  to  enforce  this
         Guaranty,  the Keep Well, the Note or any other agreement,  document or
         instrument to which Borrower,  TASL,  Lender and/or Guarantor is or are
         or may become a party,  or the waiver or consent by Lender with respect
         to any of the provisions thereof;



                                        2


<PAGE>



                           (c) the existence,  value or condition of, or failure
         to perfect its lien against,  any security for the  Obligations  or any
         action,  or the absence of any action,  by any  Beneficiary  in respect
         thereof  (including,  without  limitation,  the  release  of  any  such
         security); or

                           (d) any other  action or  circumstances  which  might
         otherwise  constitute  a legal or  equitable  discharge or defense of a
         surety or guarantor,

it being agreed by Guarantor that its obligations  under this Guaranty shall not
be discharged  until the payment and  performance,  in full, of the Obligations.
Guarantor  shall be regarded,  and shall be in the same  position,  as principal
debtor with respect to the Obligations. Guarantor expressly waives all rights it
may have now or in the future under any statute,  or at common law, or at law or
in equity,  or  otherwise,  to compel (i)  Borrower to proceed in respect of the
Obligations against TASL or any other party or (ii) Lender to proceed in respect
of the Obligations  against  Borrower or TASL or any other party, or against any
security for the payment and  performance of the Obligations  before  proceeding
against,  or as a condition to proceeding against,  Guarantor.  Guarantor agrees
that  any  notice  or  directive  given at any  time to a  Beneficiary  which is
inconsistent with the waiver in the immediately preceding sentence shall be null
and void and may be ignored by such  Beneficiary,  and, in addition,  may not be
pleaded or  introduced as evidence in any  litigation  relating to this Guaranty
for the reason that such pleading or introduction  would be at variance with the
written terms of this Guaranty,  unless such Beneficiary has specifically agreed
otherwise in writing. It is agreed among Guarantor and each of the Beneficiaries
that the foregoing waivers are of the essence of the transaction contemplated by
the Purchase  Agreement  and the Note and that,  but for this  Guaranty and such
waivers,  the Beneficiaries  would decline to enter into the Purchase  Agreement
and to deliver the Note.

                  2.2.  Demand by  Beneficiary.  In addition to the terms of the
Guaranty  set  forth in  Section  2.1  hereof,  and in no  manner  imposing  any
limitation on such terms,  it is expressly  understood  and agreed that, if TASL
has failed to make any  payments  required to be made under the Keep Well,  then
Guarantor shall,  upon demand in writing therefor by a Beneficiary to Guarantor,
pay to such Beneficiary the entire outstanding Obligations due and owing to such
Beneficiary;  provided,  however,  if  both  Beneficiaries  shall  make  demand,
Guarantor  shall make the  payment to Lender and  Borrower  shall give Lender 10
days prior written  notice of the failure of TASL to make any payments due under
the Keep Well prior to demand by Borrower  upon  Guarantor;  provided,  further,
that if at any time Lender shall notify  Guarantor  that any amounts are due and
owing to it by Borrower,  then until such notice has been revoked by Lender, any
payments to be made by Guarantor  hereunder shall be made by Guarantor  directly



                                        3


<PAGE>



to Lender and Lender  shall apply all  payments received from  Guarantor in  the
same manner as though paid directly by Borrower.

                  2.3.  Enforcement of Guaranty.  In no event shall (i) Borrower
have any obligation  (although it is entitled at its option) to proceed  against
TASL or any other Person or any real or personal  property pledged to secure the
Obligations, or (ii) Lender have any obligation (although it is entitled, at its
option) to proceed  against  Borrower or TASL or any other Person or any real or
personal property pledged to secure the Obligations, before seeking satisfaction
from  Guarantor.   A  Beneficiary  may  proceed,  prior  or  subsequent  to,  or
simultaneously with, the enforcement of such Beneficiary's rights hereunder,  to
exercise  any right or remedy which it may have  against any  property,  real or
personal, as a result of any lien it may have as security for all or any portion
of the Obligations.

                  2.4. Waiver.  In addition to the waivers  contained in Section
2.1 hereof,  Guarantor  waives,  and agrees that it shall not at any time insist
upon, plead or in any manner whatever claim or take the benefit or advantage of,
any appraisal,  valuation, stay, extension,  marshalling of assets or redemption
laws, or  exemption,  whether now or at any time  hereafter in force,  which may
delay,  prevent  or  otherwise  affect  the  performance  by  Guarantor  of  its
obligations  under, or the enforcement by the  Beneficiaries  of, this Guaranty.
Guarantor  hereby  waives   diligence,   presentment  and  demand  (whether  for
non-payment or protest or of acceptance,  maturity, extension of time, change in
nature or form of the Obligations,  acceptance of further  security,  release of
further  security,  composition or agreement  arrived at as to the amount of, or
the terms of, the Obligations,  notice of adverse change in Borrower's or TASL's
financial  condition or any other fact which might materially  increase the risk
to  Guarantor)  with  respect  to any of the  Obligations  or all other  demands
whatsoever and waives the benefit of all provisions of law which are or might be
in conflict with the terms of this Guaranty. Guarantor repre sents, warrants and
agrees  that,  as of the  date of this  Guaranty,  its  obligations  under  this
Guaranty  are not  subject to any offsets or defenses  against  Lender,  TASL or
Borrower of any kind.  Guarantor  further agrees that its obligations under this
Guaranty shall not be subject to any counterclaims,  offsets or defenses against
Lender or against Borrower or TASL of any kind which may arise in the future.

                  2.5. Benefit of Guaranty.  The provisions of this Guaranty are
for  the  benefit  of  the  Beneficiaries   and  their  respective   successors,
transferees,  endorsees and assigns,  and nothing herein contained shall impair,
as  between  TASL and  Lender  or TASL  and  Borrower,  as the case may be,  the
obligations of TASL  under the  Keep Well. In the  event all or  any part of the



                                        4


<PAGE>



Obligations are  transferred,  indorsed or assigned by  Lender to any  Person or
Persons, any reference to "Lender"  herein shall be deemed  to refer  equally to
such Person or Persons.

                  2.6.  Modification  of  Obligations,  Etc.  If  Lender  and/or
Borrower shall at any time or from time to time, with or without the consent of,
or notice to, Guarantor:

                            (a) change or extend the  manner,  place or terms of
         payment of, or renew or alter all or any portion of, the Obligations;

                            (b) take any action  under or in respect of the Keep
         Well in the  exercise  of any  remedy,  power  or  privilege  contained
         therein or available  to it at law,  equity or  otherwise,  or waive or
         refrain from exercising any such remedies, powers or privileges;

                            (c) amend or modify, in any manner  whatsoever,  the
         Keep Well;

                            (d) extend or waive the time for any of Guarantor's,
         Borrower's,  TASL's or any other Person's performance of, or compliance
         with,  any term,  covenant or  agreement on its part to be performed or
         observed  under the Keep Well, or waive such  performance or compliance
         or consent to a failure of, or  departure  from,  such  performance  or
         compliance;

                            (e) take and hold  security  or  collateral  for the
         payment  of  the  Obligations  guaranteed  hereby  or  sell,  exchange,
         release,  dispose of, or otherwise  deal with,  any  property  pledged,
         mortgaged or conveyed,  or in which Lender has been granted a lien,  to
         secure any indebtedness of Guarantor,  Borrower or TASL to Lender or of
         Guarantor or TASL to Borrower, as the case may be;

                            (f)  release  anyone who may be liable in any manner
         for the payment of any amounts owed by  Guarantor,  Borrower or TASL to
         Lender or by Guarantor or TASL to Borrower, as the case may be;

                            (g)   modify   or   terminate   the   terms  of  any
         intercreditor  or subordination  agreement  pursuant to which claims of
         other creditors of Guarantor,  Borrower or TASL are subordinated to the
         claims of Lender and/or

                            (h)  apply  any  sums by  whomever  paid or  however
         realized to any amounts owing by Guarantor,  Borrower or TASL to Lender
         or  by  Guarantor,  or TASL  to Borrower, in such manner  as Lender  or



                                        5


<PAGE>



         Borrower, as the case may be, shall determine in its discretion;

then Lender and/or Borrower shall not incur any liability to Guarantor  pursuant
hereto as a result  thereof,  and no such  action  shall  impair or release  the
obligations of Guarantor under this Guaranty.

                  2.7.  Reinstatement.  This Guaranty shall remain in full force
and effect and  continue  to be  effective  should any  petition  be filed by or
against Borrower,  TASL or Guarantor for liquidation or  reorganization,  should
Borrower,  TASL or  Guarantor  become  insolvent or make an  assignment  for the
benefit of creditors or should a receiver or trustee be appointed for all or any
significant part of Borrower's, TASL's or Guarantor's assets, and shall continue
to be effective or be reinstated, as the case may be, if at any time payment and
performance of the Obligations,  or any part thereof, is, pursuant to applicable
law,  rescinded or reduced in amount,  or must otherwise be restored or returned
by a Beneficiary,  whether as a "voidable preference",  "fraudulent conveyance",
or otherwise,  all as though such payment or  performance  had not been made. In
the  event  that any pay  ment,  or any part  thereof,  is  rescinded,  reduced,
restored or returned,  the  Obligations  shall be reinstated  and deemed reduced
only by such amount paid and not so rescinded, reduced, restored or returned.

                  2.8. Waiver of Subrogation Etc. (a) If, pursuant to applicable
law, Guarantor, by payment or otherwise, becomes subrogated to all or any of the
rights of the Beneficiaries or either of them under the Keep Well, the rights of
such  Beneficiary to which  Guarantor  shall be subrogated  shall be accepted by
Guarantor "as is" and without any representation or warranty of any kind by such
Beneficiary,  express or implied, with respect to the legality,  value, validity
or enforceability of any of such rights, or the existence,  availability, value,
merchantability  or fitness for any  particular  purpose of any  collateral  and
shall be without recourse to such Beneficiary.

                  (b) If a Beneficiary  may, under  applicable  law,  proceed to
realize its benefits  under the Keep Well,  giving such  Beneficiary a lien upon
any collateral, whether owned by TASL or by any other Person, either by judicial
foreclosure or by non-judicial sale or enforcement, such Beneficiary may, at its
sole option,  determine  which of its  remedies or rights it may pursue  without
affecting  any of its  rights  and  remedies  under  this  Guaranty.  If, in the
exercise of any of its rights and remedies,  such Beneficiary  shall forfeit any
of its rights or remedies,  including  its right to enter a deficiency  judgment
against  TASL or any  other  Person,  whether  because  of any  applicable  laws
pertaining to "election of remedies" or the like,  Guarantor  hereby consents to



                                        6


<PAGE>



such action by such  Beneficiary  and waives any claim  based upon such  action,
even if such action by such  Beneficiary  shall result in a full or partial loss
of any rights of subrogation  which  Guarantor  might otherwise have had but for
such action by such  Beneficiary.  Any election of remedies which results in the
denial or impairment of the right of a Beneficiary to seek a deficiency judgment
against TASL or any other Person shall not impair Guarantor's  obligation to pay
the full amount of the Obligations.  In the event a Beneficiary shall bid at any
foreclosure  or trustee's  sale or at any private  sale  permitted by law or the
Keep  Well,  such  Beneficiary  may bid  all or  less  than  the  amount  of the
Obligations and the amount of such bid need not be paid by such  Beneficiary but
shall be credited against the  Obligations.  The amount of the successful bid at
any such  sale,  whether  a  Beneficiary  or any other  party is the  successful
bidder,  shall  be  conclusively  deemed  to be the  fair  market  value  of the
collateral and the difference  between such bid amount and the remaining balance
of  the  Obligations  shall  be  conclusively  deemed  to be the  amount  of the
Obligations guaranteed under this Guaranty,  notwithstanding that any present or
future  law or court  decision  or ruling may have the  effect of  reducing  the
amount of any  deficiency  claim to which such  Beneficiary  might  otherwise be
entitled but for such bidding at any such sale.

                  2.9. Continuing Guaranty.  Guarantor agrees that this Guaranty
is a  continuing  guaranty  and shall  remain in full force and effect until the
payment and performance in full of the Obligations.

                  2.10. Limitation on Guaranty.  Notwithstanding anything to the
contrary  contained herein, in no event shall Guarantor's  obligation under this
Guaranty  with  respect  to  the  Obligations  exceed  an  amount  equal  to the
outstanding  Maximum  Obligation (as defined in the Keep Well) of TASL under the
Keep Well;  provided,  however,  that  nothing in this  Section 2.10 shall limit
Guarantor's  obligations  or  liabilities  in  respect  of the  representations,
warranties  and  covenants of Guarantor  set forth in this  Guaranty.  Except as
expressly set forth in this Guaranty,  Guarantor  shall have no obligation  with
respect to the Note.

                  3. REPRESENTATIONS AND WARRANTIES. To induce the Beneficiaries
to enter into the Purchase  Agreement and accept the Note,  Guarantor  makes the
following  representations and warranties to the Beneficiaries,  each and all of
which shall survive the execution and delivery of this Guaranty:

                  3.1. Corporate  Existence;  Compliance with Law. Guarantor (i)
is a corporation duly organized, validly existing and in good standing under the
laws of Bermuda;  (ii) is duly  qualified to do business and is in good standing
under the laws of each jurisdiction  where its ownership or lease of property or



                                        7


<PAGE>



the  conduct  of  its  business   requires   such   qualification   (except  for
jurisdictions  in which such  failure  so to  qualify or to be in good  standing
would not have a  materially  adverse  effect on (A) the  business,  operations,
prospects or financial condition of Guarantor, or (B) Guarantor's ability to pay
or perform the Obligations in accordance  with the terms hereof);  (iii) has the
requisite  corporate  power and  authority  and the legal right to own,  pledge,
mortgage and operate its  properties,  to lease the  property it operates  under
lease,  and to conduct  its  business  as now,  heretofore  and  proposed  to be
conducted;  (iv) has all material licenses,  permits, consents or approvals from
or by,  and has made all  material  filings  with,  and has given  all  material
notices to, all  governmental  authorities  having  jurisdiction,  to the extent
required for such  ownership,  operation and conduct;  (v) is in compliance with
its articles of incorporation and by-laws or other organizational documents; and
(vi) is in compliance with all applicable provisions of law where the failure to
so  comply  would  have  a  materially  adverse  effect  on  (A)  the  business,
operations,  prospects,  assets or financial or other  condition of Guarantor or
(B) the Guarantor's ability to pay or perform the Obligations in accordance with
the terms hereof.

                  3.2. Corporate Power; Authorization;  Enforceable Obligations.
The  execution,  delivery  and  performance  of  this  Guaranty  and  all  other
instruments  and documents to be delivered by Guarantor  hereunder and under the
Purchase  Agreement  are within  Guarantor's  corporate  powers,  have been duly
authorized by all necessary or proper corporate action, including the consent of
stockholders  where  required,  are not in  contravention  of any  provision  of
Guarantor's  articles  of  incorporation  or  by-laws  (or other  organizational
documents),  will not violate any law or  regulation,  or any order or decree of
any court or governmental  instrumentality,  will not conflict with or result in
the breach of, or constitute a default under, any indenture,  mortgage,  deed of
trust, lease,  agreement or other instrument to which Guarantor is a party or by
which Guarantor or any of its property is bound, will not result in the creation
or imposition of any lien upon any of the property of Guarantor, and the same do
not require the consent or approval of any governmental body, agency,  authority
or any other Person  except those already  obtained.  At or prior to the Closing
Date, this Guaranty and each of the Ancillary Agreements to which Guarantor is a
party  shall have been duly  executed  and  delivered  for the  benefit of or on
behalf of Guarantor,  and each shall then constitute a legal,  valid and binding
obligation of Guarantor,  enforceable  against  Guarantor in accordance with its
terms,  subject  to  the  effect  of  bankruptcy,  insolvency,   reorganization,
receivership,  moratorium  and other  similar  laws  affecting  the  rights  and
remedies of creditors  generally and, with respect to the enforceability of this
Guaranty,  by general principles of equity,  including  principles of commercial
reasonableness,  good faith and fair dealing  (regardless of whether enforcement
is sought in a proceeding at law or in equity).

                  3.3. No Material  Adverse  Change.  Since  December  31, 1996,
there has been no material adverse change in the business,  financial condition,
results of operations or liabilities of Guarantor.

                  4.  Covenants.  Guarantor hereby covenants and agrees that:

                  4.1.   Guarantor  will  not  take  any  action,   directly  or
indirectly,  to  authorize  or permit  any  amendment,  alteration  or change to
Borrower's   articles  of  organization  or  operating   agreement  (other  than
amendments  permitted under the Note),  the Keep Well, the Keep Well Guaranty or
the Loan Guaranty or permit Borrower to repeal its articles of organization.

                  4.2. Guarantor  covenants and agrees that it will not take any
action,  directly or indirectly,  to authorize or permit Borrower to take any of
the actions set forth on Annex A attached hereto;  provided,  however, that with
respect to all prohibited actions included on Annex A attached hereto, Guarantor
shall have no obligation under this Section 4.2 to provide any funds to Borrower
which  Borrower  may require in order to avoid or cure any  violation  or breach
thereof;  provided,  further  that the failure of Guarantor to change or replace
the management, directors or Persons holding similar offices of TASL or Borrower
will not be deemed, in and of itself, to constitute Guarantor's authorization or
permission of actions taken by such management, directors or Persons which cause
or result in Borrower taking any of the prohibited actions set forth on Annex A.

                  4.3.  Guarantor  shall  deliver  to Lender  (i) within 60 days
after the end of each of the first three fiscal quarters of Guarantor, a copy of
the unaudited  balance  sheet of Guarantor as of the end of such fiscal  quarter
and an unaudited  statement of income and cash flow of Guarantor for such fiscal
quarter,  all  prepared  in  accordance  with GAAP  (subject  to normal year end
adjustment),  accompanied by a certification  of the chief executive  officer or
chief  financial  officer of Guarantor  that all such  financial  statements are
complete  and correct and  present  fairly,  all in  accordance  with GAAP,  the
financial  position,  the results of  operations  and the  changes in  financial
position  of  Guarantor  as at the end of such  quarter  and for the period then
ended and (ii) within 120 days after the end of each fiscal year of Guarantor, a
copy of the audited balance sheet of Guarantor as of the end of such fiscal year
and an audited  statement of income and cash flow of  Guarantor  for such fiscal
year, all prepared in accordance  with GAAP,  accompanied by (x) a certification
of the chief executive  officer or chief financial officer of Guarantor that (1)
all such  financial  statements  are complete and correct and present  fairly in
accordance with GAAP the financial  position,  the results of operations and the



                                        9


<PAGE>



changes in  financial  position of  Guarantor as at the end of such year and for
the period then ended and (2) there have been no  amendments,  modifications  or
changes to Borrower's articles of organization or operating agreement other than
those which are permitted  pursuant the Note hereof and (y) an auditor's  report
unqualified  as to the  scope of the  audit  and as to  Guarantor  being a going
concern,  from KPMG Peat Marwick LLP, or any other firm of independent certified
public  accountants of recognized  national  standing  selected by Guarantor and
acceptable  to  Lender  together  with a  certification  from such firm that the
Economic  Interests held by all Triton Members in Borrower as of the end of such
fiscal year are, in the aggregate,  at least fifty percent (50%) of the Economic
Interests of Borrower.

                  4.4.  At  all  times,   Triton  Members  shall  hold,  in  the
aggregate, at least fifty percent (50%) of the Economic Interests of Borrower.

                  5. PERMITTED ASSIGNMENT BY LENDER. Lender may freely assign
its rights and delegate its duties under this Guaranty,  but no such  assignment
or delegation  shall  increase or diminish  Guarantor's  obligations  hereunder.
Lender shall give Guarantor  prompt notice of such  assignment or delegation and
agrees to use its best  efforts to give such notice at least three (3)  Business
Days prior to such assignment or delegation,  but the consent of Guarantor shall
not be required for any such  assignment or delegation  and failure to give such
notice shall not affect the validity or enforceability of any such assignment or
delegation or this Guaranty or subject Lender to any liability.

                  6.  FURTHER  ASSURANCES.  Guarantor  agrees,  upon the written
request of the  Beneficiaries  or either of them, to execute and deliver to such
Beneficiary,  from  time  to  time,  any  additional  instruments  or  documents
reasonably  considered  necessary by such  Beneficiary to cause this Guaranty to
be, become or remain valid and effective in accordance with its terms.

                  7. PAYMENTS FREE AND CLEAR OF TAXES. All payments  required to
be made by Guarantor hereunder shall be made to the Beneficiaries free and clear
of,  and  without   deduction  for,  any  and  all  present  and  future  taxes,
withholdings,   levies,   duties,  and  other  governmental  charges  ("Taxes"),
excluding  such income and franchise  taxes thereof which would  otherwise  have
been payable (i) by Borrower if TASL had paid the  Obligations  to Borrower,  or
(ii) by Lender if Borrower or TASL, as the case may be, had paid the Obligations
to Lender,  in accordance  with the terms of the Keep Well.  Upon request by the
Beneficiaries  or either of them,  Guarantor shall furnish to such Beneficiary a
receipt for any Taxes paid by  Guarantor  pursuant  to this  Section 6 or, if no
Taxes are payable with respect to any payments  required to be made by Guarantor
hereunder,  either a certificate  from each  appropriate  taxing authority or an



                                       10


<PAGE>



opinion of counsel  acceptable to such Beneficiary,  in either case stating that
such  payment is exempt  from or not  subject  to Taxes.  If Taxes are paid by a
Beneficiary in the good faith belief that such taxes are owing,  Guarantor will,
upon  demand  of such  Beneficiary,  and  whether  or not  such  Taxes  shall be
correctly or legally  asserted,  indemnify such  Beneficiary  for such payments,
together with any interest,  penalties and expenses in connection therewith plus
interest  thereon  at  the  lesser  of  10% or the  maximum  lawful  rate  under
applicable law. Such Beneficiary  shall  thereafter  cooperate in a commercially
reasonable manner with Guarantor in seeking any refunds of such Taxes, interest,
penalties and expenses,  which refunds and any interest thereon shall be paid by
such  Beneficiary to Guarantor  within five (5) business days of receipt by such
Beneficiary;  provided,  that in no event shall any  Beneficiary  be required to
expend its own funds in seeking any such refund and provided,  further, that any
expenses incurred in connection therewith shall be paid by Guarantor.

                  8.  MISCELLANEOUS.

                  8.1. Entire  Agreement;  Amendments.  This Guaranty,  together
with the Purchase  Agreement,  the Note,  the Keep Well and the other  Ancillary
Documents,  constitutes the entire agreement between the parties with respect to
the subject  matter hereof and  supersedes  all prior  agreements  relating to a
guaranty of payment and performance of the Obligations and may not be amended or
supplemented   except  by  a  writing  signed  by  Guarantor  and  each  of  the
Beneficiaries.

                  8.2.   Headings.   The  headings  in  this  Guaranty  are  for
convenience  of  reference  only  and are  not  part  of the  substance  of this
Guaranty.

                  8.3.  Severability.  In the event  that any one or more of the
provisions contained in this Guaranty shall be determined to be invalid, illegal
or  unenforceable  in any respect for any reason,  the  validity,  legality  and
enforceability  of any such  provision or  provisions in every other respect and
the remaining provisions of this Guaranty shall not be in any way impaired.

                  8.4.  Notices.  All notices,  demands,  declarations and other
communications  required  by this  Guaranty  shall be in  writing  and  shall be

writing and signed by such Beneficiary.

                  8.7.  Termination.  This Guaranty shall terminate and be of no

Borrower will not:

                           (a) engage in any business or activity other than (i)

                           GUARANTY (SPV INDEBTEDNESS)


                  GUARANTY,  dated as of April 1,  1997,  of TRITON  INVESTMENTS
LIMITED,  a  Bermuda  corporation  ("Guarantor"),  in favor of  TRITON  AVIATION
SERVICES V LLC, a California limited liability company ("Lender").

                              W I T N E S S E T H:

                  WHEREAS,   Triton  Aviation   Services   Limited,   a  Bermuda
corporation and a majority-owned and controlled subsidiary of Guarantor ("TASL")
is the record and beneficial  owner of 48.5% of the member  interests in each of
Lender and Triton Aviation  Services V LLC, Triton Aviation Services III LLC and
Triton Aviation  Services IV LLC, each a California  limited  liability  company
(each a "Triton LLC"; collectively, the "Triton LLC's"); and

                  WHEREAS, Guarantor, as the majority owner of TASL, will derive
substantial  direct and indirect  economic benefit from the making of loans from
time to time by Lender to the Triton LLC's ("SPV Loans"); and

                  WHEREAS,  in connection with the making of SPV Loans from time
to time to the Triton  LLC's,  Lender is  requiring  that  Guarantor  shall have
executed and delivered this Guaranty;

                  NOW,  THEREFORE,  in  consideration  of the  premises  and the
covenants hereinafter  contained,  and to induce Lender to make SPV Loans, it is
agreed as follows:

                  1.  DEFINITIONS.  The following  shall have (unless  otherwise
provided  elsewhere in this  Guaranty) the following  respective  meanings (such
meanings  being  equally  applicable to both the singular and plural form of the
terms defined):

         "Letter of  Credit"  means an  irrevocable  direct pay letter of credit
issued by a bank (i) whose long term debt is rated "AA" or better by  Thompson's
Bankwatch  or (ii)  rated "AA" or better by  Standard & Poor's in the  Financial
Institutions  Rating  Service  and  that is  payable  upon  presentation  by the
beneficiary of such Letter of Credit of a sight draft (it being understood,  but
without any  impairment of the issuing bank's  obligations  under such Letter of
Credit, that the beneficiary shall not present such sight draft unless (x) there
has been a default under the promissory note secured by such Letter of Credit or
(y) the Letter of Credit would expire within 45 days of such presentation and an






 


<PAGE>







extension of such expiration date shall not have been  granted nor an acceptable
replacement Letter of Credit been provided).

         "Obligations"  means all obligations of any kind or nature,  present or
future,  owed by any of the  Triton  LLC's to  Lender  with  respect  to any SPV
Indebtedness incurred by such Triton LLC.

         "SPV  Indebtedness"  means any and all monies  borrowed by a Triton LLC
from Lender pursuant to an SPV Loan.

         References to this "Guaranty"  shall mean this Guaranty,  including all
amendments,  modifications  and supplements and any exhibits or schedules to any
of the foregoing,  and shall refer to this Guaranty as the same may be in effect
at the time such reference becomes operative.

                  2.  THE GUARANTY.  The  guaranty of  Guarantor hereunder is as
follows:

                  2.1. Guaranty of Obligations of Triton LLC's. Guarantor hereby
unconditionally guarantees to Lender, and its respective successors,  endorsees,
transferees  and assigns,  the prompt payment  (whether at stated  maturity,  by
acceleration or otherwise) and performance of the Obligations.  Guarantor agrees
that  this  Guaranty  is a  guaranty  of  payment  and  performance  and  not of
collection,  and that its  obligations  under this  Guaranty  shall be  primary,
absolute and unconditional, irrespective of, and unaffected by:

                           (a)   the    genuineness,    validity,    regularity,
         enforceability  or any future amendment of, or change in this Guaranty,
         any SPV Indebtedness or any other agreement,  document or instrument to
         which the Triton LLC's, Lender and/or Guarantor is or are or may become
         a party;

                           (b)  the  absence  of  any  action  to  enforce  this
         Guaranty,  any SPV  Indebtedness  or any other  agreement,  document or
         instrument to which the Triton LLC's, Lender and/or Guarantor is or are
         or may become a party,  or the waiver or consent by Lender with respect
         to any of the provisions thereof;

                           (c) the existence,  value or condition of, or failure
         to perfect its lien against,  any security for the  Obligations  or any
         action, or the  absence  of an action,  by  Lender in   respect thereof





                                        2



<PAGE>







         (including, without limitationn, the release of any  such security); or

                           (d) any other  action or  circumstances  which  might
         otherwise  constitute  a legal or  equitable  discharge or defense of a
         surety or guarantor,

it being agreed by Guarantor that its obligations  under this Guaranty shall not
be discharged  until the payment and  performance,  in full, of the Obligations.
Guarantor  shall be regarded,  and shall be in the same  position,  as principal
debtor with respect to the Obligations. Guarantor expressly waives all rights it
may have now or in the future under any statute,  or at common law, or at law or
in  equity,  or  otherwise,  to  compel  Lender to  proceed  in  respect  of the
Obligations  against any Triton LLC or any other  party or against any  security
for the payment and performance of the Obligations before proceeding against, or
as a condition  to  proceeding  against,  Guarantor.  Guarantor  agrees that any
notice or directive given at any time to Lender which is  inconsistent  with the
waiver in the immediately  preceding  sentence shall be null and void and may be
ignored by Lender,  and,  in  addition,  may not be  pleaded  or  introduced  as
evidence in any  litigation  relating to this  Guaranty for the reason that such
pleading or  introduction  would be at variance  with the written  terms of this
Guaranty,  unless Lender has  specifically  agreed  otherwise in writing.  It is
agreed among Guarantor and Lender that the foregoing  waivers are of the essence
of the transactions  contemplated in connection with the making of SPV Loans and
that, but for this Guaranty and such waivers,  Lender would decline to make such
SPV Loan(s).

                  2.2. Additional  Provisions Relating to SPV Indebtedness.  (a)
Guarantor  hereby  acknowledges  and  agrees  that  it  is a  condition  to  the
incurrence of each SPV Loan that the Triton LLC incurring such SPV  Indebtedness
obtain  a  Letter  of  Credit  in  favor of  Lender  in an  amount  equal to the
outstanding  principal  amount of such SPV Loan plus six months interest thereon
(calculated at the lesser of 10% per annum and the maximum rate under applicable
law) and  Guarantor  hereby  agrees that it will cause such Triton LLC to obtain
and  maintain  in  existence  such  Letter of Credit so long as there is any SPV
Indebtedness outstanding under such SPV Loan.

         (b) Upon the failure of a Triton LLC to pay any amounts  demanded under
any  promissory  note  evidencing  any SPV  Indebtedness,  Guarantor  (i) hereby
waives,  releases  and  disclaims  any  right  of  subrogation,   reimbursement,
contribution or other similar rights against the Triton LLC that is the borrower
in respect of such SPV Indebtedness,  (ii) is hereby deemed to release,  forgive
and discharge  such Triton LLC from any obligation of such Triton LLC to pay any
amount to Guarantor in the event that Guarantor is obligated to make any payment
hereunder  or to the  issuer of any  Letter of Credit  with  respect to such SPV
Indebtedness; provided, however that any such payment by Guarantor  hereunder or





                                        3



<PAGE>







or to the  issuer of  any  Letter  of  Credit  shall be  deemed to  be a capital
contribution by Guarantor to such Triton LLC.

                  2.3.  Demand  by  Lender.  In  addition  to the  terms  of the
Guaranty set forth in Sections 2.1 and 2.2 hereof, and in no manner imposing any
limitation  on such terms,  it is expressly  understood  and agreed that, if the
then outstanding  principal amount of any of the Obligations  (together with all
accrued  interest  thereon) is declared to be immediately due and payable,  then
Guarantor  shall,  upon demand in writing  therefor by Lender to  Guarantor  but
subject  to  Section  2.6(b)  hereof,  pay  to  Lender  the  entire  outstanding
Obligations due and owing to Lender.

                  2.4.  Enforcement  of Guaranty.  In no event shall Lender have
any obligation  (although it is entitled,  at its option) to proceed against any
Triton LLC or any other  Person or any Letter of Credit or any real or  personal
property  pledged to secure the  Obligations  before seeking  satisfaction  from
Guarantor.  Lender may proceed,  prior or subsequent to, or simultaneously with,
the  enforcement of Lender's rights  hereunder,  to exercise any right or remedy
which  it may have  against  any  Letter  of  Credit  or any  property,  real or
personal, as a result of any lien it may have as security for all or any portion
of the Obligations.

                  2.5. Waiver.  In addition to the waivers  contained in Section
2.1 or 2.2 hereof,  Guarantor  waives,  and agrees that it shall not at any time
insist  upon,  plead or in any  manner  whatever  claim or take the  benefit  or
advantage of, any appraisal,  valuation, stay, extension,  marshalling of assets
or redemption laws, or exemption, whether now or at any time hereafter in force,
which may delay, prevent or otherwise affect the performance by Guarantor of its
obligations  under,  or the  enforcement by Lender of, this Guaranty.  Guarantor
hereby waives  diligence,  presentment  and demand  (whether for  non-payment or
protest or of acceptance,  maturity, extension of time, change in nature or form
of the Obligations, acceptance of further security, release of further security,
composition  or  agreement  arrived at as to the amount of, or the terms of, the
Obligations, notice of adverse change in any Triton LLC's financial condition or
any other fact which  might  materially  increase  the risk to  Guarantor)  with
respect to any of the Obligations or all other demands whatsoever and waives the
benefit  of all  provisions  of law which are or might be in  conflict  with the
terms of this Guaranty.  Guarantor  represents,  warrants and agrees that, as of
the date of this Guaranty,  its obligations  under this Guaranty are not subject
to any  offsets  or  defenses  against  Lender  or any  Triton  LLC of any kind.
Guarantor  further agrees that its obligations  under this Guaranty shall not be
subject to any counterclaims,  offsets or defenses against Lender or against any
Triton LLC of any kind which may arise in the future.

                  2.6. Benefit of Guaranty.  (a) Except as provided in paragraph
(b) below,  the provisions of this Guaranty are solely for the benefit of Lender
and its successors, transferees, endorsees and assigns. Nothing herein contained
shall  impair,  as between any Triton LLC and Lender,  the  obligations  of such
Triton  LLC  under  any SPV  Indebtedness.  In the  event all or any part of the
Obligations  are  transferred,  indorsed  or assigned by Lender to any Person or
Persons,  any  reference to "Lender"  herein shall be deemed to refer equally to
such Person or Persons.

                  (b)  Guarantor and Lender agree that this Guaranty is executed
in  part  to  induce  Polaris  Aircraft  Income  Fund  V, a  California  limited
partnership  ("Polaris"),  to enter into that certain  Purchase,  Assignment and
Assumption  Agreement  dated as of April,  1997 with  Lender  and to accept  the
delivery by Lender of that certain Promissory Note effective as of April 1, 1997
in connection  therewith,  and  accordingly  the provisions of this Guaranty are
hereby   declared  to  be  for  the  benefit  of  Polaris  and  its  successors,
transferees,  endorsees and assigns,  and may be enforced by them. Guarantor and
Lender  further  agree that in the event  Polaris  notifies  Guarantor  that any
amounts  are due and owing to it by  Lender,  then  until  such  notice has been
revoked by Polaris, any payments to be made by Guarantor hereunder shall instead
be made by  Guarantor  directly to Polaris and Polaris  shall apply all payments
received from Guarantor in the same manner as though paid directly by Lender.

                  2.7. Modification of Obligations,  Etc. If Lender shall at any
time or from time to time,  with or  without  the  consent  of,  or  notice  to,
Guarantor:

                  (a) change or extend the manner, place or terms of payment of,
or renew or alter all or any portion of, the Obligations;

                  (b)  take  any   action   under  or  in  respect  of  any  SPV
Indebtedness in the exercise of any remedy, power or privilege contained therein
or  available  to it at law,  equity  or  otherwise,  or waive or  refrain  from
exercising any such remedies, powers or privileges;

                  (c) amend or modify, in any manner  whatsoever,  any document,
instrument or agreement with respect to SPV Indebtedness;

                  (d)  extend  or waive  the time  for any of  Guarantor's,  any
Triton LLC's or other  Person's  performance  of, or compliance  with, any term,
covenant  or  agreement  on its  part to be  performed  or  observed  under  any
document,  instrument or agreement  with respect to SPV  Indebtedness,  or waive






                                        5



<PAGE>







         such performance or compliance or consent to a failure of, or departure
         from, such performance or compliance;

                           (e) take  and hold  security  or  collateral  for the
         payment  of  the  Obligations  guaranteed  hereby  or  sell,  exchange,
         release,  dispose of, or otherwise  deal with,  any  property  pledged,
         mortgaged or conveyed,  or in which Lender has been granted a lien,  to
         secure any indebtedness of Guarantor or any Triton LLC to Lender;

                           (f)  release  anyone  who may be liable in any manner
         for the payment of any amounts  owed by  Guarantor or any Triton LLC to
         Lender;

                           (g)   modify   or   terminate   the   terms   of  any
         intercreditor  or subordination  agreement  pursuant to which claims of
         other creditors of Guarantor or any Triton LLC are  subordinated to the
         claims of Lender and/or

                           (h)  apply  any  sums by  whomever  paid  or  however
         realized to any amounts  owing by Guarantor or any Triton LLC to Lender
         in such manner as Lender shall determine in its discretion;

then Lender  shall not incur any  liability to  Guarantor  pursuant  hereto as a
result  thereof,  and no such action shall impair or release the  obligations of
Guarantor under this Guaranty.

                  2.8.  Reinstatement.  This Guaranty shall remain in full force
and effect and  continue  to be  effective  should any  petition  be filed by or
against any Triton LLC or Guarantor for  liquidation or  reorganization,  should
such Triton LLC or  Guarantor  become  insolvent or make an  assignment  for the
benefit of creditors or should a receiver or trustee be appointed for all or any
significant part of such Triton LLC's or Guarantor's  assets, and shall continue
to be effective or be reinstated, as the case may be, if at any time payment and
performance of the Obligations,  or any part thereof, is, pursuant to applicable
law,  rescinded or reduced in amount,  or must otherwise be restored or returned
by Lender,  whether as a  "voidable  preference",  "fraudulent  conveyance",  or
otherwise,  all as though such payment or performance  had not been made. In the
event that any payment, or any part thereof, is rescinded,  reduced, restored or
returned,  the  Obligations  shall be reinstated and deemed reduced only by such
amount paid and not so rescinded, reduced, restored or returned.






                                        6



<PAGE>







                  2.9.  Waiver of Claims,  Etc. If Lender may, under  applicable
law, proceed to realize its benefits under any SPV Indebtedness, giving Lender a
lien upon any  collateral,  whether owned by the Triton LLC that is the borrower
under  such  SPV  Indebtedness  or by  any  other  Person,  either  by  judicial
foreclosure  or by  non-judicial  sale or  enforcement,  Lender may, at its sole
option,  determine  which  of its  remedies  or  rights  it may  pursue  without
affecting  any of its  rights  and  remedies  under  this  Guaranty.  If, in the
exercise  of any of its rights and  remedies,  Lender  shall  forfeit any of its
rights or remedies, including its right to enter a deficiency judgment against a
Triton  LLC or  any  other  Person,  whether  because  of  any  applicable  laws
pertaining to "election of remedies" or the like,  Guarantor  hereby consents to
such action by Lender and waives any claim based upon such action.  Any election
of remedies  which results in the denial or impairment of the right of Lender to
seek a  deficiency  judgment  against a Triton LLC or any other Person shall not
impair Guarantor's obligation to pay the full amount of the Obligations.  In the
event Lender shall bid at any  foreclosure  or trustee's  sale or at any private
sale permitted by law or the under any SPV  Indebtedness,  Lender may bid all or
less than the amount of the  Obligations  and the amount of such bid need not be
paid by Lender but shall be credited against the Obligations.  The amount of the
successful  bid at any such  sale,  whether  Lender  or any  other  party is the
successful bidder,  shall be conclusively  deemed to be the fair market value of
the  collateral  and the  difference  between such bid amount and the  remaining
balance of the Obligations shall be conclusively  deemed to be the amount of the
Obligations guaranteed under this Guaranty,  notwithstanding that any present or
future  law or court  decision  or ruling may have the  effect of  reducing  the
amount of any deficiency  claim to which Lender might  otherwise be entitled but
for such bidding at any such sale.

                  2.10. Continuing Guaranty. Guarantor agrees that this Guaranty
is a  continuing  guaranty  and shall  remain in full force and effect until the
payment and performance in full of the Obligations.

                  3.  REPRESENTATIONS  AND WARRANTIES.  To induce Lender to make
SPV Loans from time to time,  Guarantor makes the following  representations and
warranties  to Lender,  each and all of which shall  survive the  execution  and
delivery of this Guaranty:

                  3.1. Corporate  Existence;  Compliance with Law. Guarantor (i)
is a corporation duly organized, validly existing and in good standing under the
laws of Bermuda;  (ii) is duly  qualified to do business and is in good standing
under the laws of each jurisdiction  where its ownership or lease of property or
the  conduct  of  its  business   requires   such   qualification   (except  for
jurisdictions in  which such  failure so  to qualify  or to be  in good standing





                                        7



<PAGE>







would not have a  materially  adverse  effect on (A) the  business,  operations,
prospects or financial  condition of Guarantor or (B) Guarantor's ability to pay
the  Obligations in accordance  with the terms hereof);  (iii) has the requisite
corporate power and authority and the legal right to own,  pledge,  mortgage and
operate its  properties,  to lease the property it operates under lease,  and to
conduct its business as now,  heretofore and proposed to be conducted;  (iv) has
all material licenses,  permits,  consents or approvals from or by, and has made
all  material  filings  with,  and  has  given  all  material  notices  to,  all
governmental  authorities having  jurisdiction,  to the extent required for such
ownership,  operation  and conduct;  (v) is in  compliance  with its articles of
incorporation  and  by-laws or other  organizational  documents;  and (vi) is in
compliance with all applicable  provisions of law where the failure to so comply
would  have a  materially  adverse  effect  on  (A)  the  business,  operations,
prospects,  assets or  financial  or other  condition  of  Guarantor  or (B) the
Guarantor's ability to pay the Obligations in accordance with the terms hereof.

                  3.2. Corporate Power; Authorization;  Enforceable Obligations.
The  execution,  delivery  and  performance  of  this  Guaranty  and  all  other
instruments  and documents to be delivered by Guarantor  hereunder and under the
Purchase  Agreement  are within  Guarantor's  corporate  powers,  have been duly
authorized by all necessary or proper corporate action, including the consent of
stockholders  where  required,  are not in  contravention  of any  provision  of
Guarantor's  articles  of  incorporation  or  by-laws  (or other  organizational
documents),  will not violate any law or  regulation,  or any order or decree of
any court or governmental  instrumentality,  will not conflict with or result in
the breach of, or constitute a default under, any indenture,  mortgage,  deed of
trust, lease,  agreement or other instrument to which Guarantor is a party or by
which Guarantor or any of its property is bound, will not result in the creation
or  imposition of any lien upon any of the property of Guarantor and the same do
not require the consent or approval of any governmental body, agency,  authority
or any other Person  except those already  obtained.  At or prior to the closing
date for any SPV  Indebtedness,  this Guaranty shall have been duly executed and
delivered  for  the  benefit  of or on  behalf  of  Guarantor,  and  shall  then
constitute  a legal,  valid and binding  obligation  of  Guarantor,  enforceable
against  Guarantor  in  accordance  with its  terms,  subject  to the  effect of
bankruptcy,  insolvency,  reorganization,  receivership,  moratorium  and  other
similar laws affecting the rights and remedies of creditors  generally and, with
respect to the enforceability of this Guaranty, by general principles of equity,
including principles of commercial  reasonableness,  good faith and fair dealing
(regardless  of  whether  enforcement  is  sought in a  proceeding  at law or in
equity).

                  3.3. No Material  Adverse  Change.  Since  December  31, 1996,
there has been no material adverse change in the business,  financial condition,
results of operations or liabilities of Guarantor.

                  4.  NO ASSIGNMENT.  Neither  Guarantor  nor  Lender may assign
their respective rights or delegate their respective duties under this Guaranty.

                  5.  FURTHER  ASSURANCES.  Guarantor  agrees,  upon the written
request of Lender,  to execute  and  deliver to Lender,  from time to time,  any
additional instruments or documents reasonably considered necessary by Lender to
cause this  Guaranty to be,  become or remain valid and  effective in accordance
with its terms.

                  6. PAYMENTS FREE AND CLEAR OF TAXES. All payments  required to
be made by  Guarantor  hereunder  shall be made to Lender free and clear of, and
without  deduction  for,  any and all  present and future  taxes,  withholdings,
levies, duties, and other governmental charges ("Taxes"),  excluding such income
and franchise taxes thereof which would otherwise have been payable by Lender if
the Triton LLC that is the borrower under any SPV Indebtedness,  as the case may
be, had paid the  Obligations to Lender in accordance  with the terms of any SPV
Indebtedness.  Upon  request  by  Lender,  Guarantor  shall  furnish to Lender a
receipt for any Taxes paid by  Guarantor  pursuant  to this  Section 6 or, if no
Taxes are payable with respect to any payments  required to be made by Guarantor
hereunder,  either a certificate  from each  appropriate  taxing authority or an
opinion of  counsel  acceptable  to Lender,  in either  case  stating  that such
payment is exempt from or not  subject to Taxes.  If Taxes are paid by Lender in
the good faith belief that such taxes are owing,  Guarantor will, upon demand of
Lender,  and whether or not such Taxes shall be correctly  or legally  asserted,
indemnify  Lender for such payments,  together with any interest,  penalties and
expenses in connection  therewith plus interest  thereon at the lesser of 10% or
the maximum rate under  applicable law. Lender shall  thereafter  cooperate in a
commercially  reasonable  manner with  Guarantor  in seeking any refunds of such
taxes,  interest,  penalties and expenses which refunds and any interest thereon
shall be paid by Lender to Guarantor within five (5) business days of receipt by
Lender;  provided,  that in no event shall  Lender be required to expend its own
funds in  seeking  any such  refund and  provided,  further,  that any  expenses
incurred in connection therewith shall be paid by Guarantor.
