                  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






 










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











         (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











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.





                                        4











                  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











         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











                  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











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).






                                        8











                  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.

                  7.  MISCELLANEOUS.

                  7.1. Entire  Agreement;  Amendments.  This Guaranty,  together
with any documents, instruments and agreements with respect to SPV Indebtedness,
constitutes the entire agreement between the parties with respect to the subject





                                        9











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, Lender and Polaris.

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

                  7.3.  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.

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