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;





                  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






                           (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






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






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






         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






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:

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






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).



                                        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.  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

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

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






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
