            (d)     PREPAYMENT FEE. If Borrowers voluntarily prepay the
Obligations in full and this Agreement and all Revolving Loan Commitments are
terminated in accordance with the provisions hereof prior to the third
anniversary of the Closing Date, Borrowers shall pay to Agent, for the benefit
of Lenders, as compensation for the costs of Lenders being prepared to make
funds available to Borrowers under this Agreement, an amount determined by
MULTIPLYING the percentage set forth below by the Revolving Loan Commitment: two
percent (2.0%) for the first year following the Closing Date; one percent (1.0%)
for the second year following the Closing Date; and one-half of one percent
(1/2%) for the third year following the Closing Date. No amount will be payable
pursuant to this paragraph if Borrowers voluntarily prepay the Obligations in
full after the third anniversary of the Closing Date. The foregoing
notwithstanding, Agent and Lenders agree to waive any such prepayment fee if
such prepayment occurs after the provisions of clauses (ii), (iii) or (v) of
Section 2.2(f) have become applicable.

            (e)     COMPUTATION OF INTEREST AND RELATED FEES. All interest and
fees under each Financing Document shall be calculated on the basis of a 360-day
year for the actual number of days elapsed. The date of funding of a Prime Rate
Loan and the first day of an Interest Period with respect to a LIBOR Loan shall
be included in the calculation of interest. The date of payment of a Prime Rate
Loan and the last day of an Interest Period with respect to a LIBOR Loan shall
be excluded from the calculation of interest. If a Loan is repaid on the same
day that it is made, one (1) days' interest shall be charged. Interest on all
Prime Rate Loans is payable in arrears on the first day of each month and on the
maturity of such Loans, whether by acceleration or otherwise. Interest on LIBOR
Loans shall be payable on the last day of the applicable Interest Period, unless
the Interest Period is greater than three (3) months, in which

                                       23
<Page>

case interest will be payable on the last day of each three (3) month interval.
In addition, interest on LIBOR Loans is due on the maturity of such Loans,
whether by acceleration or otherwise.

            (f)     LIBOR PROVISIONS.

                    (i)   LIBOR ELECTION. All Loans made on the Closing Date
     shall be Prime Rate Loans and shall remain so until three (3) Business Days
     after the Closing Date. Thereafter, AAR, on its own behalf and on behalf of
     each other Borrower, may request that Revolving Loans to be made be LIBOR
     Loans, that outstanding portions of Revolving Loans be converted to LIBOR
     Loans and that all or any portion of a LIBOR Loan be continued as a LIBOR
     Loan upon expiration of the applicable Interest Period. Any such request
     will be made by submitting a Notice of Borrowing to Agent. Once given, and
     except as provided in clause (ii) below, a Notice of Borrowing shall be
     irrevocable and Borrowers shall be bound thereby. Upon the expiration of an
     Interest Period, in the absence of a new Notice of Borrowing submitted to
     Agent not less than three (3) Business Days prior to the end of such
     Interest Period, the LIBOR Loan then maturing shall be automatically
     converted to a Prime Rate Loan. There may be no more than four (4) LIBOR
     Loans outstanding at any one time. Loans which are not requested as LIBOR
     Loans in accordance with this Section 2.2(e)(i) shall be Prime Rate Loans.
     Agent will notify Lenders, by telephonic or facsimile notice, of each
     Notice of Borrowing received by Agent not less than two (2) Business Days
     prior to the first day of the Interest Period of the LIBOR Loan requested
     thereby.

                    (ii)  INABILITY TO DETERMINE LIBOR. In the event, prior to
     commencement of any Interest Period relating to a LIBOR Loan, Agent shall
     determine or be notified in writing by Required Lenders that adequate and
     reasonable methods do not exist for ascertaining LIBOR, Agent shall
     promptly provide notice of such determination to Borrowers and Lenders
     (which shall be conclusive and binding on Borrowers and Lenders). In such
     event (1) any request for a LIBOR Loan or for a conversion to or
     continuation of a LIBOR Loan shall be automatically withdrawn and shall be
     deemed a request for a Prime Rate Loan, (2) each LIBOR Loan will
     automatically, on the last day of the then current Interest Period relating
     thereto, become a Prime Rate Loan and (3) the obligations of Lenders to
     make LIBOR Loans shall be suspended until Agent or Required Lenders
     determine that the circumstances giving rise to such suspension no longer
     exist, in which event Agent shall so notify Borrowers and Lenders.

                    (iii) ILLEGALITY. Notwithstanding any other provisions
     hereof, if any law, rule, regulation, treaty or directive or interpretation
     or application thereof shall make it unlawful for any Lender to make, fund
     or maintain LIBOR Loans, such Lender shall promptly give notice of such
     circumstances to Agent, Borrower and the other Lenders. In such an event,
     (1) the commitment of such Lender to make LIBOR Loans or convert Prime Rate
     Loans to LIBOR Loans shall be immediately suspended and (2) such Lender's
     outstanding LIBOR Loans shall be converted automatically to Prime Rate
     Loans on the last day of the Interest Period thereof or at such earlier
     time as may be required by law.

                                       24
<Page>

                    (iv)  LIBOR BREAKAGE FEE. Upon (i) any default by Borrowers
     in making any borrowing of, conversion into or continuation of any LIBOR
     Loan following Borrowers' delivery to Agent of any applicable Notice of
     Borrowing or (ii) any payment of a LIBOR Loan on any day that is not the
     last day of the Interest Period applicable thereto (regardless of the
     source of such prepayment and whether voluntary, by acceleration or
     otherwise), Borrowers shall pay Agent, for the benefit of all Lenders that
     funded or were prepared to fund any such LIBOR Loan, an amount equal to the
     amount of any losses, expenses and liabilities (including, without
     limitation, any loss (including interest paid) in connection with the
     re-employment of such funds) that any Lender may sustain as a result of
     such default or such payment. For purposes of calculating amounts payable
     to a Lender under this paragraph, each Lender shall be deemed to have
     actually funded its relevant LIBOR Loan through the purchase of a deposit
     bearing interest at LIBOR in an amount equal to the amount of that LIBOR
     Loan and having a maturity and repricing characteristics comparable to the
     relevant Interest Period; PROVIDED, HOWEVER, that each Lender may fund each
     of its LIBOR Loans in any manner it sees fit, and the foregoing assumption
     shall be utilized only for the calculation of amounts payable under this
     subsection.

                    (v)   INCREASED COSTS. If, after the Closing Date, the
     adoption of, or any change in, any applicable law, rule or regulation, or
     any change in the interpretation or administration of any applicable law,
     rule or regulation by any governmental authority, central bank or
     comparable agency charged with the interpretation or administration
     thereof, or compliance by any Lender with any request or directive (whether
     or not having the force of law) of any such authority, central bank or
     comparable agency: (i) shall impose, modify or deem applicable any reserve
     (including any reserve imposed by the Board of Governors of the Federal
     Reserve System, or any successor thereto, but excluding any reserve
     included in the determination of the LIBOR pursuant to the provisions of
     this Agreement), special deposit or similar requirement against assets of,
     deposits with or for the account of, or credit extended by any Lender; or
     (ii) shall impose on any Lender any other condition affecting its LIBOR
     Loans, its Notes or its obligation to make LIBOR Loans; and the result of
     anything described in clauses (i) above and (ii) is to increase the cost to
     (or to impose a cost on) such Lender of making or maintaining any LIBOR
     Loan, or to reduce the amount of any sum received or receivable by such
     Lender under this Agreement or under its Notes with respect thereto, then
     upon demand by such Lender (which demand shall be accompanied by a
     statement setting forth the basis for such demand and a calculation of the
     amount thereof in reasonable detail, a copy of which shall be furnished to
     Agent), Borrowers shall pay directly to such Lender such additional amount
     as will compensate such Lender for such increased cost or such reduction,
     so long as such amounts have accrued on or after the day which is one
     hundred eighty (180) days prior to the date on which such Lender first made
     demand therefor.

            (g)     CAPITAL ADEQUACY. If any Lender shall reasonably determine
that any change in, or the adoption or phase-in of, any applicable law, rule or
regulation regarding capital adequacy, or any change in the interpretation or
administration thereof by any governmental authority, central bank or comparable
agency charged with the interpretation or administration thereof, or the
compliance by any Lender or any Person controlling such Lender with any request

                                       25
<Page>

or directive regarding capital adequacy (whether or not having the force of law)
of any such authority, central bank or comparable agency, has or would have the
effect of reducing the rate of return on such Lender's or such controlling
Person's capital as a consequence of such Lender's obligations hereunder or
under any Support Agreement to a level below that which such Lender or such
controlling Person could have achieved but for such change, adoption, phase-in
or compliance (taking into consideration such Lender's or such controlling
Person's policies with respect to capital adequacy) by an amount deemed by such
Lender or such controlling Person to be material, then from time to time, upon
demand by such Lender (which demand shall be accompanied by a statement setting
forth the basis for such demand and a calculation of the amount thereof in
reasonable detail, a copy of which shall be furnished to Agent), Borrowers shall
pay to such Lender such additional amount as will compensate such Lender or such
controlling Person for such reduction, so long as such amounts have accrued on
or after the day which is one hundred eighty (180) days prior to the date on
which such Lender first made demand therefor.

     SECTION 2.3    NOTES. The portion of the Revolving Loans made by each
Lender shall be evidenced by a promissory note executed by Borrowers (a
"REVOLVING LOAN NOTE") in an original principal amount equal to such Lender's
Pro Rata Share of the Revolving Loan Commitment.

     SECTION 2.4    LETTERS OF CREDIT AND LETTER OF CREDIT FEES.

            (a)     LETTER OF CREDIT. On the terms and subject to the conditions
set forth herein, Agent will prior to the Termination Date issue letters of
credit or guarantees (each, a "SUPPORT AGREEMENT") to induce an LC Issuer to
issue or increase the amount of, or extend the expiry date of, a Letter of
Credit so long as:

                    (i)   Agent shall have received a Notice of LC Credit Event
     at least two (2) Business days before the relevant date of issuance or
     increase; and

                    (ii)  After giving effect to such issuance or increase (x)
     the aggregate Letter of Credit Liabilities under all Letters of Credit do
     not exceed Five Million Dollars ($5,000,000) and (y) the Revolving Loan
     Outstandings do not exceed the Revolving Loan Limit.

            (b)     LETTER OF CREDIT FEE. Borrowers shall pay to Agent, for the
benefit of the Lenders which have committed to make Revolving Loans, a letter of
credit fee with respect to the Letter of Credit Liabilities for each Letter of
Credit, computed for each day from the date of issuance of such Letter of Credit
to the date that is the last day a drawing is available under such Letter of
Credit, at a rate per annum equal to the LIBOR Margin then applicable to
Revolving Loans. Such fee shall be payable in arrears on the first Business Day
of each calendar month prior to the Termination Date and on such date. In
addition, Borrower agrees to pay promptly to the LC Issuer any fronting or other
fees that it may charge in connection with any Letter of Credit.

            (c)     REIMBURSEMENT OBLIGATIONS OF BORROWER. If Agent shall make a
payment to an LC Issuer pursuant to a Support Agreement, Borrowers shall
promptly reimburse Agent for

                                       26
<Page>

the amount of such payment and, to the extent that so doing would not, to
Agent's knowledge, cause the Revolving Loan Outstandings to exceed the Revolving
Loan Limit, Borrowers shall be deemed to have requested a Revolving Loan, the
proceeds of which will be used to satisfy such Reimbursement Obligations.
Borrowers shall pay interest, on demand, on all amounts so paid by Agent for
each day until Borrower reimburses Agent therefor at a rate per annum equal to
the sum of two percent (2%) PLUS the interest rate applicable to Revolving Loans
(which are Prime Rate Loans) for such day.

            (d)     REIMBURSEMENT AND OTHER PAYMENTS BY BORROWER. The
obligations of Borrowers to reimburse Agent pursuant to Section 2.4(c) shall be
absolute, unconditional and irrevocable, and shall be performed strictly in
accordance with the terms of this Agreement, under all circumstances whatsoever,
including the following:

                    (i)   any lack of validity or enforceability of, or any
     amendment or waiver of or any consent to departure from, any Letter of
     Credit or any related document;

                    (ii)  the existence of any claim, set-off, defense or other
     right which any Borrower may have at any time against the beneficiary of
     any Letter of Credit, the LC Issuer (including any claim for improper
     payment), Agent, any Lender or any other Person, whether in connection with
     any Financing Document or any unrelated transaction, provided that nothing
     herein shall prevent the assertion of any such claim by separate suit or
     compulsory counterclaim;

                    (iii) any statement or any other document presented under
     any Letter of Credit proving to be forged, fraudulent, invalid or
     insufficient in any respect or any statement therein being untrue or
     inaccurate in any respect whatsoever;

                    (iv)  any affiliation between the LC Issuer and Agent; or

                    (v)   to the extent permitted under applicable law, any
     other circumstance or happening whatsoever, whether or not similar to any
     of the foregoing.

            (e)     DEPOSIT OBLIGATIONS OF BORROWERS. In the event any Letters
of Credit are outstanding at the time that Borrowers prepay or are required to
repay the Obligations or the Revolving Loan Commitment is terminated, Borrowers
shall (1) deposit with Agent for the benefit of all Lenders with a portion of
the Revolving Loan Commitment cash in an amount equal to one hundred and five
percent (105%) of the aggregate outstanding Letter of Credit Liability to be
available to Agent to reimburse payments of drafts drawn under such Letters of
Credit and pay any fees and expenses related thereto and (2) prepay the fee
payable under Section 2.4(b) with respect to such Letters of Credit for the full
remaining terms of such Letters of Credit. Upon termination of any such Letter
of Credit, the unearned portion of such prepaid fee attributable to such Letter
of Credit shall be refunded to Borrowers, together with the deposit described in
the preceding clause (1) to the extent not previously applied by Agent in the
manner described herein.

                                       27
<Page>

            (f)     PARTICIPATIONS IN SUPPORT AGREEMENTS.

                    (i)   Concurrently with the issuance of each Letter of
     Credit, Agent shall be deemed to have sold and transferred to each Lender,
     and each Lender shall be deemed irrevocably and unconditionally to have
     purchased and received from Agent, without recourse or warranty, an
     undivided interest and participation in, to the extent of such Lender's Pro
     Rata Share of the Revolving Loan Commitment, Agent's Support Agreement
     liabilities and obligations in respect of such Letters of Credit and
     Borrower's Reimbursement Obligations with respect thereto. If Borrowers do
     not pay any Reimbursement Obligation when due, then Borrowers shall be
     deemed to have immediately requested that Lenders make a Revolving Loan
     which is a Prime Rate Loan in a principal amount equal to such
     Reimbursement Obligation. Agent shall promptly notify Lenders of such
     deemed request and each Lender shall make available to Agent its Pro Rata
     Share of such Loan. The proceeds of such Loan shall be paid over by Agent
     to the LC Issuer for the account of Borrowers in satisfaction of
     reimbursement obligations then owing by Borrower to such LC Issuer in
     respect of outstanding Letters of Credit.

                    (ii)  If Agent makes any payment or disbursement under any
     Support Agreement and (x) Borrowers have not reimbursed Agent in full for
     such payment or disbursement in accordance with Section 2.4(c), (y) a
     Revolving Loan may not be made pursuant to the immediately preceding clause
     (i) or (z) any reimbursement received by Agent from Borrowers is or must be
     returned or rescinded upon or during any bankruptcy or reorganization of
     any Credit Party or otherwise, each Lender shall be irrevocably and
     unconditionally obligated to pay to Agent its Pro Rata Share of such
     payment or disbursement (but no such payment shall diminish the Obligations
     of Borrowers under Section 2.4(c)). To the extent any Lender shall not have
     made such amount available to Agent by noon (Chicago time) on the Business
     Day on which such Lender receives notice from Agent of such payment or
     disbursement, such Lender agrees to pay interest on such amount to Agent
     forthwith on demand accruing daily at the Federal Funds Rate, for the first
     three (3) days following such Lender's receipt of such notice, and
     thereafter at the Prime Rate PLUS the Prime Rate Margin in respect of
     Revolving Loans. Any Lender's failure to make available to Agent its Pro
     Rata Share of any such payment or disbursement shall not relieve any other
     Lender of its obligation hereunder to make available to Agent such other
     Lender's Pro Rata Share of such payment, but no Lender shall be responsible
     for the failure of any other Lender to make available to Agent such other
     Lender's Pro Rata Share of any such payment or disbursement.

     SECTION 2.5    GENERAL PROVISIONS REGARDING PAYMENT; LOAN ACCOUNT.

            (a)     All payments to be made by Borrowers under any Financing
Document, including payments of principal and interest on the Notes, and all
fees, expenses, indemnities and reimbursements, shall be made without set-off or
counterclaim, in lawful money of the United States of America and in immediately
available funds. If any payment hereunder becomes due and payable on a day other
than a Business Day, such payment shall be extended to the next succeeding
Business Day and, with respect to payments of principal, interest thereon shall
be payable at the then applicable rate during such extension. Borrower shall
make all payments in immediately available funds to the Payment Account before
noon (Chicago time) on the date

                                       28
<Page>

when due. Notwithstanding anything to the contrary set forth in this Section
2.5(a), Agent shall be permitted, in its sole discretion, but subject to the
limitations set forth in Section 2.1(a)(ii), to satisfy any of the payment
obligations described in this Section 2.5(a) through the making of Agent
Advances.

            (b)     Agent shall maintain a loan account (the "LOAN ACCOUNT") on
its books to record Loans and other extensions of credit made by the Lenders
hereunder or under any other Financing Document, and all payments thereon made
by Borrowers. All entries in the Loan Account shall be made in accordance with
Agent's customary accounting practices as in effect from time to time. The
balance in the Loan Account, as recorded on Agent's most recent printout or
other written statement, shall be conclusive and binding evidence of the amounts
due and owing to Agent by Borrowers absent clear and convincing evidence to the
contrary; PROVIDED that any failure to so record or any error in so recording
shall not limit or otherwise affect any Borrower's duty to pay all amounts owing
hereunder or under any other Financing Document. Unless AAR, on its own behalf
and on behalf of each other Borrower, notifies Agent in writing of any objection
to any such printout or statement (specifically describing the basis for such
objection) within thirty (30) days after the date of receipt thereof, it shall
be deemed final, binding and conclusive upon Borrowers in all respects as to all
matters reflected therein.

     SECTION 2.6    MAXIMUM INTEREST.

            (a)     In no event shall the interest charged with respect to the
Notes or any other obligations of Borrowers under any Financing Document exceed
the maximum amount permitted under the laws of the State of Illinois or of any
other applicable jurisdiction.

            (b)     Notwithstanding anything to the contrary herein or
elsewhere, if at any time the rate of interest payable hereunder or under any
Note or other Financing Document (the "STATED RATE") would exceed the highest
rate of interest permitted under any applicable law to be charged (the "MAXIMUM
LAWFUL RATE"), then for so long as the Maximum Lawful Rate would be so exceeded,
the rate of interest payable shall be equal to the Maximum Lawful Rate;
PROVIDED, that if at any time thereafter the Stated Rate is less than the
Maximum Lawful Rate, Borrowers shall, to the extent permitted by law, continue
to pay interest at the Maximum Lawful Rate until such time as the total interest
received is equal to the total interest which would have received had the Stated
Rate been (but for the operation of this provision) the interest rate payable.
Thereafter, the interest rate payable shall be the Stated Rate unless and until
the Stated Rate again would exceed the Maximum Lawful Rate, in which event this
provision shall again apply.

            (c)     In no event shall the total interest received by any Lender
exceed the amount which it could lawfully have received had the interest been
calculated for the full term hereof at the Maximum Lawful Rate. If,
notwithstanding the prior sentence, any Lender has received interest hereunder
in excess of the Maximum Lawful Rate, such excess amount shall be applied to the
reduction of the principal balance of the Loans or to other amounts (other than
interest) payable hereunder, and if no such principal or other amounts are then
outstanding, such excess or part thereof remaining shall be paid to Borrowers.

                                       29
<Page>

            (d)     In computing interest payable with reference to the Maximum
Lawful Rate applicable to any Lender, such interest shall be calculated at a
daily rate equal to the Maximum Lawful Rate divided by the number of days in the
year in which such calculation is made.

     SECTION 2.7    TAXES.

            (a)     All payments of principal and interest on the Loans and all
other amounts payable hereunder shall be made free and clear of and without
deduction for any present or future income, excise, stamp, documentary, excise,
property or franchise taxes and other taxes, fees, duties, levies, withholdings
or other charges of any nature whatsoever imposed by any taxing authority,
excluding taxes imposed on or measured by Agent's or any Lender's net income by
the jurisdiction under which Agent or such Lender is organized or conducts
business (all non-excluded items being called "TAXES"). If any withholding or
deduction from any payment to be made by any Borrower hereunder is required in
respect of any Taxes pursuant to any applicable law, rule or regulation, then
Borrowers will: (a) pay directly to the relevant authority the full amount
required to be so withheld or deducted; (b) promptly forward to Agent an
official receipt or other documentation satisfactory to Agent evidencing such
payment to such authority; and (c) pay to Agent for the account of Agent and
Lenders such additional amount or amounts as is necessary to ensure that the net
amount actually received by Agent and each Lender will equal the full amount
Agent and such Lender would have received had no such withholding or deduction
been required. If any Taxes are directly asserted against Agent or any Lender
with respect to any payment received by Agent or such Lender hereunder, Agent or
such Lender may pay such Taxes and Borrowers will promptly pay such additional
amounts (including any penalty, interest or expense) as is necessary in order
that the net amount received by such Person after the payment of such Taxes
(including any Taxes on such additional amount) shall equal the amount such
Person would have received had such Taxes not been asserted so long as such
amounts have accrued on or after the day which is one hundred eighty (180) days
prior to the date on which Agent or such Lender first made demand therefor.

            (b)     If any Borrower fails to pay any Taxes when due to the
appropriate taxing authority or fails to remit to Agent, for the account of
Agent and the respective Lenders, the required receipts or other required
documentary evidence, Borrowers shall indemnify Agent and Lenders for any
incremental Taxes, interest or penalties that may become payable by Agent or any
Lender as a result of any such failure.

            (c)     Each Lender that (i) is organized under the laws of a
jurisdiction other than the United States of America and (ii)(A) is a party
hereto on the Closing Date or (B) becomes an assignee of an interest under this
Agreement under Section 12.6(a) after the Closing Date (unless such Lender was
already a Lender hereunder immediately prior to such assignment) shall execute
and deliver to Borrowers and Agent one or more (as Borrowers or Agent may
reasonably request) Forms W-8ECI, W-8BEN, W-8IMY (as applicable) or other
applicable form, certificate or document prescribed by the United States
Internal Revenue Service certifying as to such Lender's entitlement to exemption
from withholding or deduction of Taxes. Borrowers shall not be required to pay
additional amounts to any Lender pursuant to this Section 2.7 to the extent that
the obligation to pay such additional amounts would not have arisen but for the
failure of such Lender to comply with this paragraph.

                                       30

     SECTION 2.8    ANCILLARY SERVICES. Borrowers may from time to time request,
and Agent or any Lender that is an Affiliate of a Designated Lender Affiliate
may, in its sole discretion, from time to time arrange for Borrowers, any one or
more of them or any other Credit Party to obtain from Agent or any Designated
Lender Affiliate, Ancillary Services although Borrowers or any such Credit Party
are or is not required to do so. To the extent Ancillary Services are provided,
Borrowers agree to indemnify and hold Agent and Lenders harmless from any and
all costs and obligations now or hereafter incurred by Agent or any Lenders
which arise from the indemnity given by Agent or any Lender to any Designated
Lender Affiliates related to such Ancillary Services. The agreement contained in
this Section 2.8 shall survive termination of this Agreement. Borrowers
acknowledge and agree that the obtaining of Ancillary Services (a) is in the
sole and absolute discretion of Agent and each Designated Lender Affiliate, and
(b) is subject to all rules and regulations of Agent and each applicable
Designated Lender Affiliate.

                                    ARTICLE 3
                         REPRESENTATIONS AND WARRANTIES

     To induce Agent and Lenders to enter into this Agreement and to make the
Loans and other credit accommodations contemplated hereby, each Borrower hereby
represents and warrants, on a joint and several basis, to Agent and each Lender
that:

     SECTION 3.1    EXISTENCE AND POWER. Each Credit Party is an entity as
specified on the Information Certificate, duly organized, validly existing and
in good standing under the laws of the jurisdiction specified on the Information
Certificate, has an organizational identification number (if any) as specified
on the Information Certificate, and has all powers and all governmental
licenses, authorizations, consents and approvals required to carry on its
business as now conducted, except where the failure to have such licenses,
authorizations, consents and approvals could not reasonably be expected to have
a Material Adverse Effect. Each Credit Party is qualified to do business as a
foreign entity in each jurisdiction in which it is required to be so qualified,
which jurisdictions as of the Closing Date are specified on the Information
Certificate, except where the failure to be so qualified could not reasonably be
expected to have a Material Adverse Effect.

engine parts and components for the aviation aftermarket, the design manufacture
and installation of in-plane cargo loading and handling systems for commercial
and military aircraft and helicopters and the sale or lease of used commercial
jet aircraft and the sale or lease of a wide variety of new, overhauled and
repaired commercial jet engines, as well as in certain other businesses. These
operations require financing on a basis such that the credit supplied can be
made available from time to time to Borrowers and the other Credit Parties, as
required for the continued successful operation of Borrowers and the other

                                       36
<Page>

Credit Parties taken as a whole. Borrowers and the other Credit Parties have
requested the Lenders to make credit available hereunder primarily for the
purposes provided for herein and generally for the purposes of financing the
operations of Borrowers and the other Credit Parties. Borrowers and other Credit
Party expect to derive benefit (and the Board of Directors of each Borrower and
each other Credit Party has determined that each Borrower or such other Credit
Party may reasonably be expected to derive benefit), directly or indirectly,
from a portion of the credit extended by Lenders hereunder, both in its separate
capacity and as a member of the group of companies, since the successful
operation and condition of Borrowers and each other Credit Party is dependent on
the continued successful performance of the functions of the group as a whole.
Borrowers acknowledge that, but for the agreement of each Borrower to execute
and deliver this Agreement and/or the Loan Documents, Agent and Lenders would
not have made available the credit facilities established hereby on the terms
set forth herein.

     SECTION 3.21   FULL DISCLOSURE. None of the information (financial or
otherwise) furnished by or on behalf of any Credit Party to Agent or any Lender
in connection with the consummation of the transactions contemplated by the
Operative Documents, including without limitation the information set forth in
the Information Certificate, contains any untrue statement of a material fact or
omits to state a material fact necessary to make the statements contained herein
or therein not misleading in the light of the circumstances under which such
statements were made at the time such statements were made. All financial
projections (including, without limitation, projections of Availability)
delivered to Agent and the Lenders have been or will be prepared on the basis of
the assumptions stated therein. Such projections represented or will represent
Borrowers' best estimate of Borrowers' future financial performance as of the
date such projections were prepared and such assumptions were or will be
believed by Borrowers to be fair in light of current business conditions;
provided that Borrowers can give no assurance that such projections will be
attained.

     SECTION 3.22   REPRESENTATIONS AND WARRANTIES INCORPORATED FROM OTHER
OPERATIVE DOCUMENTS. As of the Closing Date, each of the representations and
warranties made in the Operative Documents by each of the parties thereto is
true and correct in all material respects, and such representations and
warranties are hereby incorporated herein by reference with the same effect as
though set forth in their entirety herein, as qualified therein, except to the
extent that such representation or warranty relates to a specific earlier date,
in which case such representation and warranty shall be true as of such earlier
date.

     SECTION 4.2    PAYMENT AND PERFORMANCE OF OBLIGATIONS. Each Borrower (i)
will pay and discharge, at or before maturity, all of their respective
obligations and liabilities, including tax liabilities, except (x) where the
same may be the subject of a Permitted Contest and (y) for such obligations
and/or liabilities the nonpayment or nondischarge of which could not reasonably
be expected to have a Material Adverse Effect, (ii) will maintain, in accordance
with GAAP, appropriate reserves for the accrual of all of their respective
obligations and liabilities and (iii) will not breach, or permit to exist any
default under, the terms of any lease, commitment, contract, instrument or
obligation to which it is a party, or by which its properties or assets are
bound, except for such breaches or defaults which could not reasonably be
expected to have a Material Adverse Effect.

     SECTION 4.3    CONDUCT OF BUSINESS AND MAINTENANCE OF EXISTENCE. Each
Borrower will continue, to engage in business of the same general type as they
now conduct and will

                                       41
<Page>

preserve, renew and keep in full force and effect their respective existence and
their respective rights, privileges and franchises necessary or desirable in the
normal conduct of business.

     SECTION 4.4    MAINTENANCE OF PROPERTY; INSURANCE.

            (a)     Each Borrower will keep, and will cause each Subsidiary to
keep, all property useful and necessary in its business in good working order
and condition, ordinary wear and tear excepted.

            (b)     Each Borrower will maintain, and will cause each Subsidiary
to maintain, (i) physical damage insurance on all real and personal property on
an all risks basis (including the perils of flood and quake), covering the
repair and replacement cost of all such property and consequential loss coverage
for business interruption and public liability insurance (including
products/completed operations liability coverage) in each case of the kinds
customarily carried or maintained by Persons of established reputation engaged
in similar businesses and in amounts acceptable to Agent and (ii) such other
insurance coverage in such amounts and with respect to such risks as Agent may
reasonably request. All such insurance shall be provided by insurers having an
A.M. Best policyholders rating reasonably acceptable to Agent. Agent
acknowledges that the insurance coverage described on Schedule 4.4 meets the
requirements of this Section 4.4 subject to Agent's future right to review such
insurance in light of changing economic and business conditions.

            (c)     On or prior to the Closing Date, Borrowers will cause Agent
to be named as an additional insured, assignee and, only with respect to the
Collateral, mortgagee or loss payee, as applicable, on each insurance policy
required to be maintained pursuant to this Section 4.4 pursuant to endorsements
in form and content acceptable to Agent. Borrowers will deliver to Agent and the
Lenders (i) on the Closing Date, a certificate from Borrowers' insurance broker
dated such date showing the amount of coverage as of such date, and that such
policies will include effective waivers (whether under the terms of any such
policy or otherwise) by the insurer of all claims for insurance premiums against
all mortgagee or loss payees and additional insureds and all rights of
subrogation against all loss payees and additional insureds, and that if all or
any part of such policy is canceled, terminated or expires, the insurer will
forthwith give notice thereof to each additional insured mortgagee and loss
payee and that no cancellation, reduction in amount or material change in
coverage thereof shall be effective until at least thirty (30) days after
receipt by each additional insured mortgagee and loss payee of written notice
thereof, (ii) on an annual basis, and upon the request of any Lender through
Agent from time to time, full information as to the insurance carried, (iii)
within five (5) days of receipt of notice from any insurer, a copy of any notice
of cancellation, nonrenewal or material change in coverage from that existing on
the date of this Agreement and (iv) forthwith, notice of any cancellation or
nonrenewal of coverage by any Borrower.

            (d)     In the event Borrowers fail to provide Agent with evidence
of the insurance coverage required by this Agreement, Agent may purchase
insurance at Borrowers' expense to protect Agent's interests in the Collateral.
This insurance may, but need not, protect any Borrower's interests. The coverage
purchased by Agent may not pay any claim made by any Borrower or any claim that
is made against any Borrower in connection with the Collateral. Borrowers may
later cancel any insurance purchased by Agent, but only after providing Agent

                                       42
<Page>

with evidence that Borrowers have obtained insurance as required by this
Agreement. If Agent purchases insurance for the Collateral, Borrowers will be
responsible for the costs of that insurance, including interest and other
charges imposed by Agent in connection with the placement of the insurance,
until the effective date of the cancellation or expiration of the insurance. The
costs of the insurance may be added to the Obligations. The costs of the
insurance may be more than the cost of insurance Borrowers are able to obtain on
their own.

     SECTION 4.5    COMPLIANCE WITH LAWS. Each Borrower will comply, and cause
each Subsidiary to comply, with the requirements of all applicable laws,
ordinances, rules, regulations, and requirements of governmental authorities
(including Environmental Laws and ERISA and the rules and regulations
thereunder), except for such laws, ordinances, rules, regulations and
requirements the noncompliance with which could not reasonably be expected to
have a Material Adverse Effect.

     SECTION 4.6    INSPECTION OF PROPERTY, BOOKS AND RECORDS. Each Borrower
will keep, and will cause each Subsidiary to keep, proper books of record and
account in accordance with GAAP in which full, true and correct entries shall be
made of all dealings and transactions in relation to its business and
activities; and will permit, and will cause each Subsidiary to permit, at the
sole cost of Borrowers or any applicable Subsidiary, representatives of Agent
and of any Lender (but at such Lender's expense unless such visit or inspection
is made concurrently with Agent) to visit and inspect any of their respective
properties, to examine and make abstracts or copies from any of their respective
books and records, to conduct a collateral audit and analysis of their
respective Inventory and Accounts and to discuss their respective affairs,
finances and accounts with their respective officers, employees and independent
public accountants as often as may reasonably be desired. Unless an Event of
Default has occurred and is continuing, all such visits and inspections shall be
during normal business hours with reasonable advance notice.

     SECTION 4.7    USE OF PROCEEDS. Borrowers will use the proceeds of the
Revolving Loans solely for transaction fees incurred in connection with the
Operative Documents, the refinancing on the Closing Date of Debt owing to a
Person not an Affiliate of any Credit Party and for working capital needs of
Borrowers and the Subsidiaries.

     SECTION 4.8    LENDERS' MEETINGS. At the request of Agent, within
forty-five (45) days after the end of each fiscal quarter, Borrowers will
conduct a meeting of Agent and the Lenders to discuss such fiscal quarter's
results and the financial condition of Borrowers and the Subsidiaries at which
shall be present a Responsible Officer and such officers of the Credit Parties
as may be reasonably requested to attend by Agent or any Lender, such request or
requests to be made within a reasonable time prior to the scheduled date of such
meeting. Such meetings shall be held at a time and place convenient to the
Lenders and to Borrowers.

     SECTION 4.9    HAZARDOUS MATERIALS; REMEDIATION. Borrowers will provide
Agent within thirty (30) days after demand therefor with a bond, letter of
credit or similar financial assurance evidencing to the satisfaction of Agent
that sufficient funds are available to pay the cost of removing, treating and
disposing of any Hazardous Materials or Hazardous Materials Contamination and
discharging any assessment which may be established on any Real Property as a
result thereof, such demand to be made, if at all, upon Agent's reasonable
business

                                       43
<Page>

determination that the failure to remove, treat or dispose of any Hazardous
Materials or Hazardous Materials Contamination, or the failure to discharge any
such assessment could reasonably be expected to have a Material Adverse Effect.
At Agent's option, in lieu of any such bond, letter of credit or similar
financial assurance, Agent may create a Reserve to insure the payment of any
such cost or assessment.

     SECTION 4.10   FURTHER ASSURANCES. Each Borrower will, at its own cost and
expense, cause to be promptly and duly taken, executed, acknowledged and
delivered all such further acts, documents and assurances as may from time to
time be necessary or as Agent or the Required Lenders may from time to time
reasonably request in order to carry out the intent and purposes of the
Financing Documents and the transactions contemplated thereby, including all
such actions to establish, preserve, protect and perfect a first priority Lien
(subject only to Permitted Liens) in favor of Agent for the benefit of the
Lenders on the Collateral (including Collateral acquired after the date hereof),
including on any and all assets of each Borrower, whether now owned or hereafter
acquired. In addition, upon request by Agent, Borrowers shall deliver or shall
cause a Subsidiary to deliver to Agent mortgages or deeds of trust and mortgagee
title insurance policies, all in form and substance reasonably acceptable to
Agent, for Borrowers' Real Property in Wood Dale, Illinois or Garden City, New
York, if any Permitted Mortgage Debt is not closed with respect to either
facility by the date which is four months after the Closing Date.

                                    ARTICLE 5

and no Borrower will permit any Subsidiary (except to facilitate a transaction
in which such Subsidiary will incur Permitted Mortgage Debt) to, (i) acquire or
create any Subsidiary or (ii) engage, outside of the ordinary course of

<Page>

be obtained from a third party, no Borrower will, and no Borrower will permit

into a control agreement regarding such bank account pursuant to which such bank
acknowledges the security interest of Agent in such bank account, agrees to
comply with instructions originated by Agent directing disposition of the funds
in the bank account without further consent from the applicable Borrower, and
agrees to subordinate and limit any security interest the bank may have in the

                     ACCOUNTS AND INVENTORY REPRESENTATIONS,
                      WARRANTIES, COVENANTS AND AGREEMENTS

     To induce Agent and Lenders to enter into this Agreement and to make the
Loans and other credit accommodations contemplated hereby, each Borrower hereby,
on a joint and several basis, represents and warrants to Agent and each Lender,
and further agrees with Agent and each Lender, that:

     SECTION 6.1    ACCOUNTS AND ACCOUNT COLLECTIONS.

            (a)     Upon request by Agent, after an Event of Default has
occurred and is continuing, each Borrower shall establish and maintain, at its
sole expense, and shall cause each Domestic Subsidiary to establish and
maintain, at its sole expense blocked accounts or lockboxes and related blocked
accounts (in either case, "BLOCKED ACCOUNTS"), as Agent may specify, with such
banks as are acceptable to Agent into which each Borrower and its Domestic
Subsidiaries shall promptly deposit and direct their respective Account Debtors
to directly remit all payments on Accounts (other than Accounts sold by AAR
Receivables Corporation II pursuant to the Securitization Documents to the
extent such Accounts have not been reconveyed to the applicable Borrower
pursuant to Section 3.4 of the Purchase and Sale Agreement) or the Company Note
and all payments constituting proceeds of Inventory or other Collateral in the
identical form in which such payments are made, whether by cash, check or other
manner; PROVIDED, HOWEVER, that any payments which constitute proceeds of
property not included in the Collateral shall be excluded from the Blocked
Accounts and the requirements of this Section. Each Borrower shall deliver, or
cause to be delivered, to Agent a Deposit Account Control Agreement duly
authorized, executed and delivered by each bank where a Blocked Account for the
benefit of such Borrower or any of its Domestic Subsidiaries is maintained, and
by each bank where any other Deposit Account is from time to time maintained.
Each Borrower shall further execute and deliver, and shall cause each of its
Domestic Subsidiaries to execute and deliver, such agreements and documents as
Agent may require in connection with such Blocked Accounts, Deposit Accounts and
such Deposit Account Control Agreements. Without limiting the provisions of
Section 5.13, after the occurrence and during the continuance of an Event of
Default, no Borrower shall establish, and each Borrower shall cause each of its
Domestic Subsidiaries not to establish, any Deposit Accounts not existing as of
the Closing Date, unless such Borrower or its Domestic Subsidiaries (as
applicable) have complied in full with the provisions of this Section 6.1 with
respect to such Deposit Accounts. Each Borrower agrees that all payments made to
such Blocked Accounts or other funds received and collected by Agent or any
Lender, whether in respect of the Accounts, as proceeds of Inventory or other
Collateral or otherwise shall be treated as payments to Agent and Lenders in
respect of the Obligations and therefore shall constitute the property of Agent
and Lenders to the extent of the then outstanding Obligations.

            (b)     For purposes of calculating the amount of the Loans
available to Borrower, payments made to a Blocked Account will be applied
(conditional upon final collection) to the Obligations on the Business Day of
receipt by Agent of immediately available funds in the Payment Account provided
such payments and notice thereof are received in accordance with Agent's usual
and customary practices as in effect from time to time and with

                                       52
<Page>

sufficient time to credit the Loan Account on such day, and if not, then on the
next Business Day. For the purposes of calculating interest on the Obligations,
such payments or other funds received shall be deemed applied (conditional upon
final collection) to the Obligations following the date of receipt of
immediately available funds by Agent in the Payment Account provided such
payments or other funds and notice thereof are received in accordance with
Agent's usual and customary practices as in effect from time to time and with
sufficient time to credit the Loan Account on such day, and if not, then on the
next Business Day.

            (c)     After an Event of Default has occurred and is continuing,
each Borrower and its directors, employees, agents, Subsidiaries and other
Affiliates shall, acting as trustee for Agent, receive, as the property of
Agent, any monies, checks, notes, drafts or any other payment relating to and/or
proceeds of Accounts (other than Accounts sold by AAR Receivables Corporation II
pursuant to the Securitization Documents), Inventory or other Collateral which
come into their possession or under their control and immediately upon receipt
thereof, shall deposit or cause the same to be deposited in the Blocked
Accounts, or remit the same or cause the same to be remitted, in kind, to Agent.
In no event shall the same be commingled with any Borrower's own funds. Each
Borrower agrees to reimburse Agent on demand for any amounts owed or paid to any
bank at which a Blocked Account is established or any other bank or Person
involved in the transfer of funds to or from the Blocked Accounts arising out of
Agent's payments to or indemnification of such bank or Person.

            (d)     No Borrower or other Credit Party shall commingle any
proceeds of any of its Accounts with the proceeds of any Account sold to AAR
Receivables Corporation II (or any other single purpose Subsidiary formed for
the purpose of facilitating a securitization), except temporary commingling as
permitted by the Receivables Purchase Agreement, unless any such sold Account is
subsequently reconveyed to a Borrower or other Credit Party pursuant to Section
3.4 of the Purchase and Sale Agreement. Each Borrower and each other Credit
Party shall diligently maintain for its Accounts Deposit Accounts and books,
records and accounts thereof for its Accounts separate from the Accounts, the
Deposit Accounts and books and records and accounts therefor of AAR Receivables
Corporation II.

     SECTION 6.2    INVENTORY. (a) With respect to the Inventory: (i) each
Borrower shall at all times maintain, and cause each of its Subsidiaries to
maintain, records of Inventory reasonably satisfactory to Agent, keeping correct
and accurate records itemizing and describing the kind, type, quality and
quantity of Inventory, the cost therefor and daily withdrawals therefrom and
additions thereto; (ii) each Borrower shall conduct, and cause each of its
Subsidiaries to conduct, a physical count of the Inventory at least once each
year but at any time or times as Agent may request on or after an Event of
Default, and promptly following such physical inventory shall supply Agent with
a report in the form and with such specificity as may be satisfactory to Agent
concerning such physical count; (iii) except as otherwise provided on a
Borrowing Base Certificate, no Borrower shall sell, and no Borrower shall permit
any of its Subsidiaries to sell, Inventory to any customer on approval, or any
other basis which entitles the customer to return (except for the right of
customers for Inventory which is defective or non-conforming) or may obligate
any Credit Party to repurchase such Inventory; (iv) except as otherwise provided
on a Borrowing Base Certificate, each Borrower shall keep, and shall cause each
of its Subsidiaries to keep, the Inventory in good and marketable condition; and
(v) except as otherwise provided on a Borrowing Base Certificate, no Borrower
shall acquire or accept, and

                                       53
<Page>

no Borrower shall permit any of its Subsidiaries to acquire or accept, without
prior written notice to Agent, any Inventory on consignment or approval. Each
Borrower shall and shall cause each of its Subsidiaries to maintain all of its
Inventory, in all material respects, in compliance with such Borrower's or
Subsidiary's FAA approved maintenance program and all other applicable FAA and
other governmental laws, rules and regulations. Without limiting the generality
of the foregoing, all FAA Airworthiness Directives and amendments or changes to
the Federal Aviation Regulations applicable to any such Inventory and Equipment,
as well as all mandatory service bulletins applicable to any such Inventory and
Equipment, shall have been accomplished, in all material respects, by
terminating action in compliance with the issuing agency's or the manufacturer's
specific instructions. No Inventory shall be included in Eligible Inventory if
any such Inventory has become an accession to any airplane, airplane engine or
other personal property other than Inventory that is subject to first priority
Liens in favor of Agent for its benefit and the ratable benefit of Lenders.

            (b)     Borrowers acknowledge and agree that Agent shall from time
to time obtain, at Borrowers' expense, appraisals from appraisers (who may be
personnel of an Agent), stating the then current Net Orderly Liquidation Value
of Inventory or the value of Equipment included within the Collateral consisting
of aircraft and aircraft engines. Such appraisals shall be in form, scope and
methodology acceptable to Agent. Each Borrower shall, and shall cause each of
its Domestic Subsidiaries to assist Agent or any such appraiser in the
preparation of any such appraisals.

            (c)     None of the inventory or equipment subject to the Air France
Parts Lease shall be included as Eligible Inventory or was included in the SH&E
appraisal delivered to Agent prior to the Closing Date.

                                    ARTICLE 7

Multiemployer Pension Plans as a result of such withdrawal (including any
outstanding withdrawal liability that any Credit Party or any member of the

$3,000,000;

            (i)     one or more judgments or orders for the payment of money

event remains unstayed and in effect for any period of ten (10) days.

     SECTION 9.2    ACCELERATION AND SUSPENSION OR TERMINATION OF REVOLVING LOAN
COMMITMENT. Upon the occurrence and during the continuance of an Event of
Default, Agent may, and shall if requested by Required Lenders, (i) by notice to
Borrowers suspend or terminate the Revolving Loan Commitment, in whole or in
part (and, if in part, such reduction shall be pro rata among the Lenders having
a Revolving Loan Commitment Percentage) and/or (ii) by notice to Borrowers
declare the Obligations to be, and the Obligations shall thereupon become,
immediately due and payable without presentment, demand, protest or other notice
of any kind, all of which are hereby waived by Borrowers and Borrowers will pay
the same; provided that in the case of any of the Events of Default specified in
Section 9.1(f) or 9.1(g) above, without any notice to Borrowers or any other act
by Agent or the Lenders, the Revolving Loan Commitment shall thereupon terminate
and all of the Obligations shall become immediately due and payable

                                       58
<Page>

without presentment, demand, protest or other notice of any kind, all of which
are hereby waived by Borrowers and Borrowers will pay the same.

     SECTION 9.3    CASH COLLATERAL. If (i) any Event of Default specified in
Section 9.1(f) or 9.1(g) shall occur, (ii) the Obligations shall have otherwise
been accelerated pursuant to Section 9.2 or (iii) the Revolving Loan Commitment
shall have been terminated pursuant to Section 9.2, then without any request or
the taking of any other action by Agent or the Lenders, Borrowers shall
immediately comply with the provisions of Section 2.4(e) with respect to the
deposit of cash collateral to secure the existing Letter of Credit Liability and
future payment of related fees.

     SECTION 9.4    DEFAULT RATE OF INTEREST AND SUSPENSION OF LIBOR RATE
OPTIONS. At the election of Agent or Required Lenders, after the occurrence of
an Event of Default and for so long as it continues, the Loans and other
Obligations shall bear interest at rates that are two percent (2.0%) in excess
of the rates otherwise payable under this Agreement. Furthermore, at the
election of Agent or Required Lenders during any period in which any Event of
Default is continuing (x) as the Interest Periods for LIBOR Loans then in effect
expire, such Loans shall be converted into Prime Rate Loans and (y) the LIBOR
election will not be available to Borrowers.

     SECTION 9.5    SETOFF RIGHTS. During the continuance of any Event of
Default, each Lender is hereby authorized by each Borrower at any time or from
time to time, with reasonably prompt subsequent notice to Borrowers (any prior
or contemporaneous notice being hereby expressly waived) to set off and to
appropriate and to apply any and all (A) balances held by such Lender at any of
its offices for the account of any Borrower or any of its Subsidiaries
(regardless of whether such balances are then due to any Borrower or its
Subsidiaries), and (B) other property (unless such property secures Debt (other
than the Obligations) permitted hereby) at any time held or owing by such Lender
to or for the credit or for the account of any Borrower or any of its
Subsidiaries, against and on account of any of the Obligations; except that no
Lender shall exercise any such right without the prior written consent of Agent.
Any Lender exercising a right to set off shall purchase for cash (and the other
Lenders shall sell) interests in each of such other Lender's Pro Rata Share of
the Obligations as would be necessary to cause all Lenders to share the amount
so set off with each other Lender in accordance with their respective Pro Rata
Share of the Obligations. Each Borrower agrees, to the fullest extent permitted
by law, that any Lender may exercise its right to set off with respect to the
Obligations as provided in this Section 9.5.

     SECTION 9.6    APPLICATION OF PROCEEDS. Notwithstanding anything to the
contrary contained in this Agreement, upon the occurrence and during the
continuance of an Event of Default, (a) each Borrower irrevocably waives the
right to direct the application of any and all payments at any time or times
thereafter received by Agent from or on behalf of any Borrower or any guarantor
of all or any part of the Obligations, and Agent shall have the continuing and
exclusive right to apply and to reapply any and all payments received at any
time or times after the occurrence and during the continuance of an Event of
Default against the Obligations in such manner as Agent may deem advisable
notwithstanding any previous application by Agent and (b) in the absence of a
specific determination by Agent with respect thereto, the proceeds of any sale
of, or other realization upon, all or any part of the Collateral shall be
applied: FIRST, to all fees, costs, indemnities and expenses incurred by or
owing to Agent and any Designated Lender

                                       59
<Page>

Affiliate that is an Affiliate of Agent, with respect to this Agreement, the
other Financing Documents, any Ancillary Services or the Collateral; SECOND, to
all fees, costs, indemnities and expenses incurred by or owing to any Lender and
any Designated Lender Affiliate that is an Affiliate of any Lender, with respect
to this Agreement, the other Financing Documents, any Ancillary Services or the
Collateral; THIRD, to accrued and unpaid interest on the Obligations (including
any interest which but for the provisions of the U.S. Bankruptcy Code, would
have accrued on such amounts); FOURTH, to the principal amount of the
Obligations outstanding; and FIFTH to any other indebtedness or obligations of
any Borrower owing to Agent, any Lender or any Designated Lender Affiliate under
the Financing Documents or with respect to Ancillary Services. Any balance
remaining shall be delivered to Borrowers or to whomever may be lawfully
entitled to receive such balance or as a court of competent jurisdiction may
direct.

     SECTION 9.7    NON-RECOURSE GUARANTORS. Notwithstanding any other provision
of this Agreement or any of the other Financing Documents, Lenders' and Agent's
sole right to recover from each Non-Recourse Guarantor shall be limited to the
Collateral pledged by such Non-Recourse Guarantor and no Lender or Agent, acting
on behalf of Lenders, shall have any right of recourse against any other asset
of such Non-Recourse Guarantor nor against such Non-Recourse Guarantor
individually.

                 EXPENSES, INDEMNITY, TAXES AND RIGHT TO PERFORM

     SECTION 10.1   EXPENSES. Borrowers hereby agree to promptly pay (i) all
reasonable costs and expenses of Agent (including without limitation the fees,
costs and expenses of counsel to, and independent appraisers and consultants
retained by Agent) in connection with the examination, review, due diligence
investigation, documentation, negotiation and closing of the transactions
contemplated by the Financing Documents, in connection with the performance by
Agent of its rights and remedies under the Financing Documents and in connection
with the continued administration of the Financing Documents including any
amendments, modifications, consents and waivers to and/or under any and all
Financing Documents, (ii) without limitation of the preceding clause (i), all
reasonable costs and expenses of Agent in connection with the creation,
perfection and maintenance of Liens pursuant to the Financing Documents,
including title investigations, (iii) without limitation of the preceding clause
(i), expenses of Agent in connection with protecting, storing, insuring,

workout, collection, bankruptcy, insolvency and other enforcement proceedings
under any and all of the Financing Documents, and (iv) all costs and expenses
incurred by Lenders in connection with any workout, collection, bankruptcy,
insolvency and other enforcement proceedings under any and all Financing
Documents, provided, that to the extent that the costs and expenses referred to
in this clause (iv) consist of fees, costs and expenses of counsel, Borrowers
shall be obligated to pay such reasonable fees, costs and expenses for only one
counsel acting for all Lenders (including Agent).

     SECTION 10.2   INDEMNITY. Borrowers hereby agree to indemnify, pay and hold
harmless Agent and Lenders and the officers, directors, employees and counsel of
Agent and Lenders (collectively called the "INDEMNITEES") from and against any
and all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, claims, costs, expenses and disbursements of any kind or
nature whatsoever (including the fees and disbursements of counsel for such

                                       60
<Page>

Indemnitee) in connection with any investigative, administrative or judicial
proceeding, whether or not such Indemnitee shall be designated a party thereto
and including any such proceeding initiated by or on behalf of a Borrower, and
the reasonable expenses of investigation by engineers, environmental consultants
and similar technical personnel and any commission, fee or compensation claimed
by any broker (other than any broker retained by Agent or Lenders) asserting any
right to payment for the transactions contemplated hereby, which may be imposed
on, incurred by or asserted against such Indemnitee as a result of or in
connection with the transactions contemplated hereby or by the other Operative
Documents (including (i)(A) as a direct or indirect result of the presence on or
under, or escape, seepage, leakage, spillage, discharge, emission or release
from, any Real Property now or previously owned, leased or operated by any
Borrower, any Subsidiary or any other Person of any Hazardous Materials or any
Hazardous Materials Contamination, (B) arising out of or relating to the offsite
disposal of any materials generated or present on any such Real Property or (C)
arising out of or resulting from the environmental condition of any such Real
Property or the applicability of any governmental requirements relating to
Hazardous Materials, whether or not occasioned wholly or in part by any
condition, accident or event caused by any act or omission of any Borrower or
any Subsidiary, and (ii) proposed and actual extensions of credit under this
Agreement) and the use or intended use of the proceeds of the Notes and Letters
of Credit, except that Borrowers shall have no obligation hereunder to an
Indemnitee with respect to any liability resulting from the gross negligence or
willful misconduct of such Indemnitee, as determined by a court of competent
jurisdiction. To the extent that the undertaking set forth in the immediately
preceding sentence may be unenforceable, Borrowers shall contribute the maximum
portion which it is permitted to pay and satisfy under applicable law to the
payment and satisfaction of all such indemnified liabilities incurred by the
Indemnitees or any of them.

     SECTION 10.3   TAXES. Borrowers agree to pay all governmental assessments,
charges or taxes (except income or other similar taxes imposed on Agent or
Lenders), including any interest or penalties thereon, at any time payable or
ruled to be payable in respect of the existence, execution or delivery of this
Agreement or the other Financing Documents or the issuance of the Notes or
Letters of Credit and to indemnify and hold Agent and Lenders harmless against
liability in connection with any such assessments, charges or taxes.

     SECTION 10.4   RIGHT TO PERFORM. If any Credit Party fails to perform any
obligation hereunder or under any other Financing Document, Agent itself may,
but shall not be obligated to, cause such obligation to be performed at
Borrowers' expense and Borrowers agree to reimburse Agent therefor on demand.
All amounts owing hereunder or under any other Financing Document may be
satisfied in full, subject to the provisions of Section 2.2(a)(ii), through the
making of Agent Advances.

                                   ARTICLE 11
                                      AGENT

     SECTION 11.1   APPOINTMENT AND AUTHORIZATION. Each Lender hereby
irrevocably appoints and authorizes Agent to enter into each of the Security
Documents on its behalf and to take such actions as Agent on its behalf and to
exercise such powers under the Financing Documents as are delegated to Agent by
the terms thereof, together with all such powers as are reasonably incidental
thereto. Except as otherwise expressly provided in Section 12.5 or by the

                                       61
<Page>

terms of the Financing Documents, Agent is authorized and empowered to amend,
modify, or waive any provisions of this Agreement or the other Financing
Documents on behalf of Lenders. The provisions of this Article 11 are solely for
the benefit of Agent and Lenders and neither any Borrower nor any other Credit
Party shall have any rights as a third party beneficiary of any of the
provisions hereof. In performing its functions and duties under this Agreement,
Agent shall act solely as agent of Lenders and does not assume and shall not be
deemed to have assumed any obligation toward or relationship of agency or trust
with or for any Borrower or any other Credit Party. Agent may perform any of its
duties hereunder, or under the Financing Documents, by or through its agents or
employees.

     SECTION 11.2   AGENT AND AFFILIATES. Agent shall have the same rights and
powers under the Financing Documents as any other Lender and may exercise or
refrain from exercising the same as though it were not Agent, and Agent and its
Affiliates may lend money to, invest in and generally engage in any kind of
business with each Credit Party or Affiliate of any Credit Party as if it were
not Agent hereunder.

     SECTION 11.3   ACTION BY AGENT. The duties of Agent shall be mechanical and
administrative in nature. Agent shall not have by reason of this Agreement a
fiduciary relationship in respect of any Lender. Nothing in this Agreement or
any of the Financing Documents, express or implied, is intended to or shall be
construed to impose upon Agent any obligations in respect of this Agreement or
any of the Financing Documents except as expressly set forth herein or therein.

     SECTION 11.4   CONSULTATION WITH EXPERTS. Agent may consult with legal
counsel, independent public accountants and other experts selected by it and
shall not be liable for any action taken or omitted to be taken by it in good
faith in accordance with the advice of such counsel, accountants or experts.

     SECTION 11.5   LIABILITY OF AGENT. Neither Agent nor any of its directors,
officers, agents or employees shall be liable to any Lender for any action taken
or not taken by it in connection with the Financing Documents, except that Agent
shall be liable to the extent of its own gross negligence or willful misconduct
as determined by a court of competent jurisdiction. Neither Agent nor any of its
directors, officers, agents or employees shall be responsible for or have any
duty to ascertain, inquire into or verify (i) any statement, warranty or
representation made in connection with any Financing Document or any borrowing
hereunder; (ii) the performance or observance of any of the covenants or
agreements specified in any Financing Agreement; (iii) the satisfaction of any
condition specified in any Financing Document, except receipt of items required
to be delivered to Agent; (iv) the validity, effectiveness, sufficiency or
genuineness of any Financing Document, any Lien purported to be created or
perfected thereby or any other instrument or writing furnished in connection
therewith; (v) the existence or non-existence of any Default or Event of
Default; or (vi) the financial condition of any Credit Party. Agent shall not
incur any liability by acting in reliance upon any notice, consent, certificate,
statement, or other writing (which may be a bank wire, telex, facsimile or
electronic transmission or similar writing) believed by it to be genuine or to
be signed by the proper party or parties. Agent shall not be liable for any
apportionment or distribution of payments made by it in good faith and if any
such apportionment or distribution is subsequently determined to have been made
in error the sole recourse of any Lender to whom payment was due but not made,
shall be to recover

                                       62
<Page>

from other Lenders any payment in excess of the amount to which they are
determined to be entitled (and such other Lenders hereby agree to return to such
Lender any such erroneous payments received by them).

     SECTION 11.6   INDEMNIFICATION. Each Lender shall, in accordance with its
Pro Rata Share, indemnify Agent (to the extent not reimbursed by Borrowers)
against any cost, expense (including counsel fees and disbursements), claim,
demand, action, loss or liability (except such as result from Agent's gross
negligence or willful misconduct as determined by a court of competent
jurisdiction) that Agent may suffer or incur in connection with the Financing
Documents or any action taken or omitted by Agent hereunder or thereunder. If
any indemnity furnished to Agent for any purpose shall, in the opinion of Agent,
be insufficient or become impaired, Agent may call for additional indemnity and
cease, or not commence, to do the acts indemnified against even if so directed
by Required Lenders until such additional indemnity is furnished. The
obligations of Lenders under this Section 11.6 shall survive the payment in full
of the Obligations and the termination of this Agreement.

     SECTION 11.7   RIGHT TO REQUEST AND ACT ON INSTRUCTIONS. Agent may at any
time request instructions from Lenders with respect to any actions or approvals
which by the terms of this Agreement or of any of the Financing Documents Agent
is permitted or desires to take or to grant, and if such instructions are
promptly requested, Agent shall be absolutely entitled to refrain from taking
any action or to withhold any approval and shall not be under any liability
whatsoever to any Person for refraining from any action or withholding any
approval under any of the Financing Documents until it shall have received such
instructions from Required Lenders or all or such other portion of the Lenders
as shall be prescribed by this Agreement. Without limiting the foregoing, no
Lender shall have any right of action whatsoever against Agent as a result of
Agent acting or refraining from acting under this Agreement or any of the other
Financing Documents in accordance with the instructions of Required Lenders and,
notwithstanding the instructions of Required Lenders, Agent shall have no
obligation to take any action if it believes, in good faith, that such action
exposes Agent to any liability for which it has not received satisfactory
indemnification in accordance with the provisions of Section 11.6.

     SECTION 11.8   CREDIT DECISION. Each Lender acknowledges that it has,
independently and without reliance upon Agent or any other Lender, and based on
such documents and information as it has deemed appropriate, made its own credit
analysis and decision to enter into this Agreement. Each Lender also
acknowledges that it will, independently and without reliance upon Agent or any
other Lender, and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or
not taking any action under the Financing Documents.

     SECTION 11.9   COLLATERAL MATTERS. Lenders irrevocably authorize Agent, at
its option and in its discretion, to release any Lien granted to or held by
Agent under any Security Document (i) upon termination of the Revolving Loan
Commitment and payment in full of all Obligations and the expiration,
termination or cash collateralization (to the satisfaction of Agent) of all
Letters of Credit; or (ii) constituting property sold or to be sold or disposed
of as part of or in connection with any disposition permitted under any
Financing Document (it being understood and agreed that Agent may conclusively
rely without further inquiry on a certificate of a Responsible Officer as to the
sale or other disposition of property being made in full

                                       63
<Page>

compliance with the provisions of the Financing Documents). Upon request by
Agent at any time, Lenders will confirm in writing Agent's authority to release
particular types or items of Collateral pursuant to this Section 11.9.

     SECTION 11.10  AGENCY FOR PERFECTION. Agent and each Lender hereby appoint
each other Lender as agent for the purpose of perfecting Agent's security
interest in assets which, in accordance with the Uniform Commercial Code in any
applicable jurisdiction, can be perfected by possession or control. Should any
Lender (other than Agent) obtain possession or control of any such assets, such
Lender shall notify Agent thereof, and, promptly upon Agent's request therefore,
shall deliver such assets to Agent or in accordance with Agent's instructions or
transfer control to Agent in accordance with Agent's instructions. Each Lender
agrees that it will not have any right individually to enforce or seek to
enforce any Security Document or to realize upon any Collateral for the Loans
unless instructed to do so by Agent, it being understood and agreed that such
rights and remedies may be exercised only by Agent.

     SECTION 11.11  NOTICE OF DEFAULT. Agent shall not be deemed to have
knowledge or notice of the occurrence of any Default or Event of Default except
with respect to defaults in the payment of principal, interest and fees required
to be paid to Agent for the account of Lenders, unless Agent shall have received
written notice from a Lender or Borrowers referring to this Agreement,
describing such Default or Event of Default and stating that such notice is a
"notice of default". Agent will notify each Lender of its receipt of any such
notice. Agent shall take such action with respect to such Default or Event of
Default as may be requested by Required Lenders in accordance with the terms
hereof. Unless and until Agent has received any such request, Agent may (but
shall not be obligated to) take such action, or refrain from taking such action,
with respect to such Default or Event of Default as it shall deem advisable or
in the best interests of Lenders.

     SECTION 11.12  SUCCESSOR AGENT. Agent may resign at any time by giving
written notice thereof to the Lenders and Borrowers. Upon any such resignation,
Required Lenders shall have the right to appoint a successor Agent. If no
successor Agent shall have been so appointed by Required Lenders, and shall have
accepted such appointment, within thirty (30) days after the retiring Agent
gives notice of resignation, then the retiring Agent may, on behalf of Lenders,
appoint a successor Agent, which shall be an institution organized or licensed
under the laws of the United States of America or of any State thereof. Upon the
acceptance of its appointment as Agent hereunder by a successor Agent, such
successor Agent shall thereupon succeed to and become vested with all the rights
and duties of the retiring Agent, and the retiring Agent shall be discharged
from its duties and obligations hereunder. After any retiring Agent's
resignation hereunder as Agent, the provisions of this Article shall inure to
its benefit as to any actions taken or omitted to be taken by it while it was
Agent.

     SECTION 11.13  DISBURSEMENTS OF REVOLVING LOANS; PAYMENT.

            (a)     REVOLVING LOAN ADVANCES, PAYMENTS AND SETTLEMENTS; INTEREST
AND FEE PAYMENTS.

                    (i)   Agent shall have the right, on behalf of Lenders, to
     disburse funds to Borrowers for all Revolving Loans requested by AAR, on
     its own behalf and on behalf

                                       64
<Page>

     of each other Borrower pursuant to the terms of this Agreement. Absent the
     prior receipt by Agent of a written notice from any Lender pursuant to
     which such Lender notifies Agent that such Lender shall cease making
     Revolving Loans (whether due to the existence of a Default or Event of
     Default or otherwise), Agent shall be conclusively entitled to assume, for
     purposes of the preceding sentence, that each Lender will fund its Pro Rata
     Share of all Revolving Loans requested by Borrower. Each Lender shall
     reimburse Agent on demand, in accordance with the provisions of the
     immediately following paragraph, for all funds disbursed on its behalf by
     Agent pursuant to the preceding sentence, or if Agent so requests, each
     Lender will remit to Agent its Pro Rata Share of any Revolving Loan before
     Agent disburses the same to Borrowers. If Agent elects to require that each
     Lender make funds available to Agent, prior to a disbursement by Agent to
     Borrowers, Agent shall advise each Lender by telephone, facsimile or e-mail
     of the amount of such Lender's Pro Rata Share of the Revolving Loan
     requested by AAR on its own behalf and on behalf of each other Borrower no
     later than noon (Chicago time) on the date of funding of such Revolving
     Loan, and each such Lender shall pay Agent on such date such Lender's Pro
     Rata Share of such requested Revolving Loan, in same day funds, by wire
     transfer to the Payment Account, or such other account as may be identified
     in writing by Agent to Lenders from time to time. If any Lender fails to
     pay the amount of its Pro Rata Share within one (1) Business Day after
     Agent's demand, Agent shall promptly notify Borrowers, and Borrowers shall
     immediately repay such amount to Agent. Any repayment required pursuant to
     this Section 11.13 shall be without premium or penalty. Nothing in this
     Section 11.13 or elsewhere in this Agreement or the other Financing
     Documents shall be deemed to require Agent to advance funds on behalf of
     any Lender or to relieve any Lender from its obligation to fulfill its
     commitments hereunder or to prejudice any rights that Agent or Borrowers
     may have against any Lender as a result of any default by such Lender
     hereunder.

                    (ii)  On a Business Day of each week as selected from time
     to time by Agent, or more frequently (including daily), if Agent so elects
     (each such day being a "SETTLEMENT DATE"), Agent will advise each Lender by
     telephone, facsimile or e-mail of the amount of each such Lender's Pro Rata
     Share of the Revolving Loan balance (including any Agent Advances) as of
     the close of business of the Business Day immediately preceding the
     Settlement Date. In the event that payments are necessary to adjust the
     amount of such Lender's actual Pro Rata Share of the Revolving Loan balance
     to such Lender's required Pro Rata Share of the Revolving Loan balance as
     of any Settlement Date, the party from which such payment is due (i) shall
     be deemed, irrevocably and unconditionally, to have purchased, without
     recourse or warranty, an undivided interest and participation in the
     Revolving Loans sufficient to equate such Lender's actual Pro Rata Share of
     the Revolving Loan balance as of such Settlement Date with such Lender's
     required Pro Rata Share of the Revolving Loans as of such date and (ii)
     shall pay Agent, without setoff or discount, in same day funds, by wire
     transfer to the Payment Account not later than noon (Chicago time) on the
     Business Day following the Settlement Date the full purchase price for such
     interest and participation, equal to one hundred percent (100%) of the
     principal amount of the Revolving Loans being purchased and sold. In the
     event settlement shall not have occurred by the date and time specified in
     the immediately preceding sentence, interest shall accrue on the unsettled
     amount at the

                                       65
<Page>

     Federal Funds Rate, for the first three (3) days following the scheduled
     date of settlement, and thereafter at the Prime Rate PLUS the Prime Rate
     Margin.

                    (iii) On each Settlement Date, Agent shall advise each
     Lender by telephone, facsimile or e-mail of the amount of such Lender's Pro
     Rata Share of principal, interest and fees paid for the benefit of Lenders
     with respect to each applicable Loan, to the extent of such Lender's credit
     exposure with respect thereto, and shall make payment to such Lender not
     later than noon (Chicago time) on the Business Day following the Settlement
     Date of such amounts in accordance with wire instructions delivered by such
     Lender to Agent, as the same may be modified from time to time by written
     notice to Agent; provided, that, in the case such Lender is a Defaulted
     Lender, Agent shall be entitled to set off the funding short-fall against
     that Defaulted Lender's respective share of all payments received from
     Borrowers.

                    (iv)  The provisions of this Section 11.13(a) shall be
     deemed to be binding upon Agent and Lenders notwithstanding the occurrence
     of any Default or Event of Default, or any insolvency or bankruptcy
     proceeding pertaining to any Borrower or any other Credit Party.

            (b)     RETURN OF PAYMENTS.

                    (i)   If Agent pays an amount to a Lender under this
     Agreement in the belief or expectation that a related payment has been or
     will be received by Agent from any Borrower and such related payment is not
     received by Agent, then Agent will be entitled to recover such amount from
     such Lender on demand without setoff, counterclaim or deduction of any
     kind, together with interest accruing on a daily basis at the Federal Funds
     Rate.

                    (ii)  If Agent determines at any time that any amount
     received by Agent under this Agreement must be returned to any Borrower or
     paid to any other Person pursuant to any insolvency law or otherwise, then,
     notwithstanding any other term or condition of this Agreement or any other
     Financing Document, Agent will not be required to distribute any portion
     thereof to any Lender. In addition, each Lender will repay to Agent on
     demand any portion of such amount that Agent has distributed to such
     Lender, together with interest at such rate, if any, as Agent is required
     to pay to such Borrower or such other Person, without setoff, counterclaim
     or deduction of any kind.

            (c)     DEFAULTED LENDERS. The failure of any Defaulted Lender to
make any Revolving Loan or any payment required by it hereunder shall not
relieve any other Lender of its obligations to make such Revolving Loan or
payment, but neither any Lender nor Agent shall be responsible for the failure
of any Defaulted Lender to make a Revolving Loan or make any other payment
required hereunder. Notwithstanding anything set forth herein to the contrary, a
Defaulted Lender shall not have any voting or consent rights under or with
respect to any Financing Document or constitute a "Lender" (or be included in
the calculation of "Required Lenders" hereunder) for any voting or consent
rights under or with respect to any Financing Document. At Borrowers' request,
Agent or a Person reasonably acceptable to Agent shall have the right with
Agent's consent and in Agent's sole discretion (but shall have no obligation) to

                                       66
<Page>

purchase from any Defaulted Lender, and each Defaulted Lender agrees that it
shall, at Agent's request, sell and assign to Agent or such Person, all of the
lending commitments and commitment interests of that Defaulted Lender for an
amount equal to the principal balance of all Loans held by such Defaulted Lender
and all accrued interest and fees with respect thereto through the date of sale,
such purchase and sale to be consummated pursuant to an executed Assignment
Agreement.

the payment of the Obligations and any termination of this Agreement.

     SECTION 12.2   NO WAIVERS. No failure or delay by Agent or any Lender in
exercising any right, power or privilege under any Financing Document shall
operate as a waiver thereof nor shall any single or partial exercise thereof

     SECTION 12.4   SEVERABILITY. In case any provision of or obligation under
this Agreement or the Notes or any other Financing Document shall be invalid,
illegal or unenforceable in any jurisdiction, the validity, legality and
enforceability of the remaining provisions or obligations, or of such provision
or obligation in any other jurisdiction, shall not in any way be affected or
impaired thereby.

     SECTION 12.5   AMENDMENTS AND WAIVERS. Any provision of this Agreement or
the Notes may be amended or waived if, but only if, such amendment or waiver is
in writing and is signed by Borrowers and the Required Lenders (and, if (x) any
amendment would increase either such Lender's Revolving Loan Commitment Amount
by such Lender and (y) the rights or duties of Agent or LC Issuer are affected
thereby, by Agent or the LC Issuer, as the case may be);

                                       67
<Page>

provided that no such amendment or waiver shall, unless signed by all the

respect to any Loan or Reimbursement Obligation; (ii) postpone the date fixed
for any payment (other than a payment pursuant to Section 2.1(c)) of principal
of any Loan, or of any Reimbursement Obligation or of interest on any Loan or
any Reimbursement Obligation or any fees hereunder or for any termination of any
commitment; (iii) change the definition of the term Required Lenders or the
percentage of Lenders which shall be required for Lenders to take any action

in the definition of Borrowing Base by more than $1,000,000 set forth in the
Borrowing Base Certificate.

     SECTION 12.6   ASSIGNMENTS; PARTICIPATIONS.

            (a)     ASSIGNMENTS.

                    (i)   Any Lender may at any time assign to one or more
     Persons (any such Person, an "ASSIGNEE") all or any portion of such
     Lender's Loans and interest in the Revolving Loan Commitment, with the
     prior written consent of Agent and, so long as no Event of Default exists,
     Borrowers (which consent shall not be unreasonably withheld or delayed and
     shall not be required for an assignment by a Lender to a Lender or to an
     Affiliate of a Lender). Except as Agent may otherwise agree, any such
     assignment shall be in a minimum aggregate amount equal to $5,000,000 or,
     if less, the assignor's entire interests in the Revolving Loan Commitment
     and outstanding Loans. Borrowers and Agent shall be entitled to continue to
     deal solely and directly with such Lender in connection with the interests
     so assigned to an Assignee until Agent shall have received and accepted an
     effective Assignment Agreement executed, delivered and fully completed by
     the applicable parties thereto and a processing fee of $3,500. Any
     attempted assignment not made in accordance with this Section 12.6(a) shall
     be treated as the sale of a participation under Section 12.6(b). Borrowers
     shall be deemed to have granted its consent to any assignment requiring its
     consent hereunder unless Borrowers have expressly objected to such
     assignment within three (3) Business Days after notice thereof.

                    (ii)  From and after the date on which the conditions
     described above have been met, (i) such Assignee shall be deemed
     automatically to have become a party hereto and, to the extent that rights
     and obligations hereunder have been assigned to such Assignee pursuant to
     such Assignment Agreement, shall have the rights and obligations of a
     Lender hereunder and (ii) the assigning Lender, to the extent that rights
     and obligations hereunder have been assigned by it pursuant to such
     Assignment Agreement, shall be released from its rights (other than its
     indemnification rights) and obligations hereunder. Upon the request of the
     Assignee (and, as applicable, the assigning Lender) pursuant to an
     effective Assignment Agreement, Borrowers shall execute and deliver to
     Agent for delivery to the Assignee (and, as applicable, the assigning
     Lender) Notes in the aggregate principal amount of the Assignee's
     percentage interest in the Revolving Loan

                                       68
<Page>

     Commitment (and, as applicable, Notes in the principal amount of that
     portion of the Revolving Loan Commitment retained by the assigning Lender).
     Upon receipt by the assigning Lender of such Note, the assigning Lender
     shall return to Borrowers any prior Note held by it.

                    (iii) Agent shall maintain at one of its offices a copy of
     each Assignment Agreement delivered to it and a register for the
     recordation of the names and addresses of each Lender, and the commitments
     of, and principal amount of the Loans owing to, such Lender pursuant to the
     terms hereof. The entries in such register shall be conclusive, and
     Borrowers, Agent and Lenders may treat each Person whose name is recorded
     therein pursuant to the terms hereof as a Lender hereunder for all purposes
     of this Agreement, notwithstanding notice to the contrary. Such register
     shall be available for inspection by Borrowers and any Lender, at any
     reasonable time upon reasonable prior notice to Agent.

                    (iv)  Notwithstanding the foregoing provisions of this
     Section 12.6(a) or any other provision of this Agreement, any Lender may at
     any time assign all or any portion of its Loans and its Note as collateral
     security to a Federal Reserve Bank or, as applicable, to such Lender's
     trustee for the benefit of its investors (but no such assignment shall
     release any Lender from any of its obligations hereunder).

            (b)     PARTICIPATIONS. Any Lender may at any time sell to one or
more Persons participating interests in its Loans, commitments or other
interests hereunder (any such Person, a "PARTICIPANT"). In the event of a sale
by a Lender of a participating interest to a Participant, (a) such Lender's
obligations hereunder shall remain unchanged for all purposes, (b) Borrowers and
Agent shall continue to deal solely and directly with such Lender in connection
with such Lender's rights and obligations hereunder and (c) all amounts payable
by Borrowers shall be determined as if such Lender had not sold such
participation and shall be paid directly to such Lender. No Participant shall
have any direct or indirect voting rights hereunder except with respect to any
event described in Section 12.5 expressly requiring the unanimous vote of all
Lenders or, as applicable, all affected Lenders. Each Lender agrees to
incorporate the requirements of the preceding sentence into each participation
agreement which such Lender enters into with any Participant. Borrowers agree
that if amounts outstanding under this Agreement are due and payable (as a
result of acceleration or otherwise), each Participant shall be deemed to have
the right of set-off in respect of its participating interest in amounts owing
under this Agreement and with respect to any Letter of Credit to the same extent
as if the amount of its participating interest were owing directly to it as a
Lender under this Agreement; provided that such right of set-off shall be
subject to the obligation of each Participant to share with Lenders, and Lenders
agree to share with each Participant, as provided in Section 9.5.

     SECTION 12.7   HEADINGS. Headings and captions used in the Financing
Documents (including the Exhibits, Schedules and Annexes hereto and thereto) are
included for convenience of reference only and shall not be given any
substantive effect.

     SECTION 12.8   CONFIDENTIALITY. In handling any confidential information of
any Credit Party, Agent and each Lender shall exercise the same degree of care
that it exercises with respect to its own proprietary information of the same
types to maintain the confidentiality of any non-public

                                       69
<Page>

information thereby received or received pursuant to this Agreement, except that
disclosure of such information may be made (i) to agents, employees,
Subsidiaries, Affiliates, attorneys and advisors of such Person in connection
with its present or prospective business relations with the Credit Parties
arising out of the Financing Documents, (ii) to prospective transferees or
purchasers of any interest in the Loans, provided that they have agreed to be
bound by the provision of this Section 12.8, (iii) as required by law,
regulation, rule, request or order, subpoena, judicial order or similar order
and in connection with any litigation and (iv) as may be required in connection
with the examination, audit or similar investigation of such Person.
Confidential information shall include only such information identified as such
at the time provided to Agent and shall not include information that either: (i)
is in the public domain, or becomes part of the public domain after disclosure
to such Person through no fault of such Person, or (ii) is disclosed to such
Person by a third party, provided Agent does not have actual knowledge that such
third party is prohibited from disclosing such information.

     SECTION 12.9   GOVERNING LAW; SUBMISSION TO JURISDICTION. THIS AGREEMENT,
EACH NOTE AND EACH OTHER FINANCING DOCUMENT SHALL BE GOVERNED BY, AND SHALL BE
CONSTRUED AND ENFORCED IN ACCORDANCE WITH THE LAWS OF THE STATE OF ILLINOIS,
WITHOUT REGARD TO CONFLICTS OF LAWS PRINCIPLES. EACH BORROWER HEREBY CONSENTS TO
THE JURISDICTION OF ANY STATE OR FEDERAL COURT LOCATED WITHIN THE COUNTY OF
COOK, STATE OF ILLINOIS AND IRREVOCABLY AGREES THAT, SUBJECT TO AGENT'S
ELECTION, ALL ACTIONS OR PROCEEDINGS ARISING OUT OF OR RELATING TO THIS
AGREEMENT OR THE OTHER FINANCING DOCUMENTS SHALL BE LITIGATED IN SUCH COURTS.
EACH BORROWER EXPRESSLY SUBMITS AND CONSENTS TO THE JURISDICTION OF THE
AFORESAID COURTS AND WAIVES ANY DEFENSE OF FORUM NON CONVENIENS. EACH BORROWER
HEREBY WAIVES PERSONAL SERVICE OF ANY AND ALL PROCESS AND AGREES THAT ALL SUCH
SERVICE OF PROCESS MAY BE MADE UPON SUCH BORROWER BY CERTIFIED OR REGISTERED
MAIL, RETURN RECEIPT REQUESTED, ADDRESSED TO SUCH BORROWER AT THE ADDRESS SET
FORTH IN THIS AGREEMENT AND SERVICE SO MADE SHALL BE COMPLETE TEN (10) DAYS
AFTER THE SAME HAS BEEN POSTED.

     SECTION 12.10  WAIVER OF JURY TRIAL. EACH OF EACH BORROWER, AGENT AND THE
LENDERS HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY
LEGAL ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THE FINANCING DOCUMENTS
OR THE TRANSACTIONS CONTEMPLATED THEREBY AND AGREES THAT ANY SUCH ACTION OR
PROCEEDING SHALL BE TRIED BEFORE A COURT AND NOT BEFORE A JURY.

     SECTION 12.11  PUBLICATION; ADVERTISEMENT.

            (a)     PUBLICATION. No Credit Party will directly or indirectly
publish, disclose or otherwise use in any public disclosure, advertising
material, promotional material, press release or interview, any reference to the
name, logo or any trademark of Merrill Lynch or any of its

                                       70
<Page>

Affiliates or any reference to this Agreement or the financing evidenced hereby,
in any case without Merrill Lynch's prior written consent.

            (b)     ADVERTISEMENT. Each Credit Party hereby authorizes Merrill
Lynch to publish the name of such Credit Party and the amount of the financing
evidenced hereby in any "tombstone" or comparable advertisement which Merrill
Lynch elects to publish. In addition, each Credit Party agrees that Merrill
Lynch may provide lending industry trade organizations with information
necessary and customary for inclusion in league table measurements after the
Closing Date. With respect to any of the foregoing, Merrill Lynch shall provide
Borrowers with an opportunity to review and confer with Merrill Lynch regarding
the contents of any such tombstone, advertisement or information, as applicable,
prior to its publication.

     SECTION 12.12  COUNTERPARTS; INTEGRATION. This Agreement and the other
Financing Documents may be signed in any number of counterparts, each of which
shall be an original, with the same effect as if the signatures thereto and
hereto were upon the same instrument. This Agreement and the other Financing
Documents constitute the entire agreement and understanding among the parties
hereto and supersede any and all prior agreements and understandings, oral or
written, relating to the subject matter hereof.

     SECTION 12.13  REIMBURSEMENT. The undertaking by Borrowers to repay the
Obligations and each representation, warranty or covenant of each Borrower are
and shall be joint and several. To the extent that any Borrower shall be
required to pay a portion of the Obligations which shall exceed the amount of
loans, advances or other extensions of credit received by any such Borrower and
all interest, costs, fees and expenses attributable to such loans, advances or
other extensions of credit, then such Borrower shall be reimbursed by the other
Borrower for the amount of such excess. This Section 12.13 is intended only to
define the relative rights of Borrowers, and nothing set forth in Section 12.13
is intended or shall impair the obligations of each Borrower, jointly and
severally, to pay to Agent and Lenders the Obligations as and when the same
shall become due and payable in accordance with the terms hereof.

[MERRILL LYNCH LOGO]        Exhibit A to Credit Agreement (Assignment Agreement)

     This Assignment Agreement (this "ASSIGNMENT AGREEMENT") is entered into as
of __________ by and between the Assignor named on the signature page hereto
("ASSIGNOR") and the Assignee named on the signature page hereto ("ASSIGNEE").
Reference is made to the Credit Agreement dated as of May 29, 2003 (as amended
or otherwise modified from time to time, the "CREDIT AGREEMENT") among AAR
Corp., AAR Distribution, Inc., AAR Parts Trading, Inc., AAR Manufacturing, Inc.,
AAR Engine Services, Inc. and AAR Allen Services, Inc. (individually, a
"BORROWER" and collectively "BORROWERS"), the financial institutions party
thereto from time to time, as Lenders, and Merrill Lynch Capital, a division of
Merrill Lynch Business Financial Services Inc., as Agent. Capitalized terms used
herein and not otherwise defined shall have the meanings assigned to them in the
Credit Agreement.

     Assignor and Assignee hereby agree as follows:

     1.  Assignor hereby sells and assigns to Assignee, and Assignee hereby
purchases and assumes from Assignor the interests set forth on the schedule
attached hereto (the "SCHEDULE"), in and to Assignor's rights and obligations
under the Credit Agreement as of the effective date set forth on the Schedule
(the "EFFECTIVE DATE"). Such purchase and sale is made without recourse,
representation or warranty except as expressly set forth herein. On the
Effective Date, Assignee shall pay to Assignor an amount equal to the aggregate
amounts assigned pursuant to the Schedule (exclusive of unfunded portions of the
Revolving Loan Commitment) and Assignor shall pay to Assignee a closing fee in
respect of the transactions contemplated hereby in the amount specified on the
Schedule.

     2.  Assignor (i) represents that as of the Effective Date, that it is the
legal and beneficial owner of the interests assigned hereunder free and clear of
any adverse claim, (ii) makes no other representation or warranty and assumes no
responsibility with respect to any statement, warranties or representations made
in or in connection with the Credit Agreement or the execution, legality,
validity, enforceability, genuineness, sufficiency or value of the Credit
Agreement, any other Financing Documents or any other instrument or document
furnished pursuant thereto; and (iii) makes no representation or warranty and
assumes no responsibility with respect to the financial condition of any other
Credit Party or any other Person or the performance or observance by any Credit
Party of its Obligations under the Credit Agreement or any other Financing
Documents or any other instrument or document furnished pursuant thereto.

     3.  Assignee (i) confirms that it has received a copy of the Credit
Agreement and the other Financing Documents, together with copies of the most
recent financial statements delivered pursuant thereto and such other documents
and information as it has deemed appropriate to make its own credit analysis and
decision to enter into this Assignment Agreement; (ii) agrees that it will,
independently and without reliance upon Agent, Assignor or any other Lender and
based on such documents and information as it shall deem appropriate at the
time, continue to make its own credit decisions in taking or not taking action
under the Credit Agreement; (iii) appoints and authorizes Agent to take such
action as agent on its behalf and to exercise such powers under the Credit
Agreement and the other Financing Documents as are

                               Exhibit A - Page 1
<Page>

delegated to Agent by the terms thereof, together with such powers as are
reasonably incidental thereto; (iv) agrees that it will perform in accordance
with their terms all obligations which by the terms of the Credit Agreement are
required to be performed by it as a Lender; (v) represents that on the date of
this Assignment Agreement it is not presently aware of any facts that would
cause it to make a claim under the Credit Agreement; (vi) represents and
warrants that Assignee is not a foreign person (i.e., a person other than a
United States person for United States Federal income tax purposes) or, if it is
a foreign person, that it has delivered to Agent the documentation required to
be delivered to Agent by Section 13 below; and (vii) represents and warrants
that it has experience and expertise in the making or the purchasing of loans
such as the Loans, and that it has acquired the interests described herein for
its own account and without any present intention of selling all or any portion
of such interests.

     4.  Each of Assignor and Assignee represents and warrants to the other
party hereto that it has full power and authority to enter into this Assignment
Agreement and to perform its obligations hereunder in accordance with the
provisions hereof, that this Assignment Agreement has been duly authorized,
executed and delivered by such party and that this Assignment Agreement
constitutes a legal, valid and binding obligation of such party, enforceable
against such party in accordance with its terms, except as enforceability may be
limited by applicable bankruptcy, insolvency, reorganization, moratorium or
other similar laws affecting creditors' rights generally and by general
principles of equity.

     5.  Upon the effectiveness of this Assignment Agreement pursuant to Section
13 below, (i) Agent shall register Assignee as a Lender, pursuant to the terms
of the Credit Agreement, (ii) Assignee shall be a party to the Credit Agreement
and, to the extent provided in this Assignment Agreement, have the rights and
obligations of a Lender thereunder, (iii) Assignor shall, to the extent provided
in this Assignment Agreement, relinquish its rights and be released from its
obligations under the Credit Agreement and (iv) Agent shall thereafter make all
payments in respect of the interest assigned hereby (including payments of
principal, interest, fees and other amounts) to Assignee. Assignor and Assignee
shall make all appropriate adjustments in payments for periods prior to the
Effective Date by Agent or with respect to the making of this assignment
directly between themselves.

     6.  Each of Assignor and Assignee hereby agrees from time to time, upon
request of the other such party hereto, to take such additional actions and to
execute and deliver such additional documents and instruments as such other
party may reasonably request to effect the transactions contemplated by, and to
carry out the intent of, this Assignment Agreement.

     7.  Neither this Assignment Agreement nor any term hereof may be changed,
waived, discharged or terminated, except by an instrument in writing signed by
the party (including, if applicable, any party required to evidence its consent
to or acceptance of this Assignment Agreement) against whom enforcement of such
change, waiver, discharge or termination is sought.

     8.  For the purposes hereof and for purposes of the Credit Agreement, the
notice address of Assignee shall be as set forth on the Schedule. Any notice or
other communication herein required or permitted to be given shall be in writing
and delivered in accordance with the notice provisions of the Credit Agreement.

shall be invalid, illegal or unenforceable in any jurisdiction, the validity,
legality and enforceability of the remaining provisions or obligations, or of
such provision or obligation in any other jurisdiction, shall not in any way be
affected or impaired thereby.

     10. THIS ASSIGNMENT AGREEMENT SHALL BE GOVERNED BY, AND SHALL BE CONSTRUED
AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF ILLINOIS, WITHOUT
REGARD TO CONFLICTS OF LAWS PRINCIPLES.

     11. This Assignment Agreement shall be binding upon, and shall inure to the
benefit of, the parties hereto and their respective successors and assigns.

each of which shall be an original, with the same effect as if the signatures
hereto were upon the same agreement.

Date upon the satisfaction of each of the following conditions: (i) the
execution of a counterpart hereof by each of Assignor and Assignee, (ii) the
execution of a counterpart hereof by each of Agent and Borrowers as evidence of

Credit Agreement, (iii) the receipt by Agent of the administrative fee referred
to in Section 12.6(a) of the Credit Agreement, (iv) in the event Assignee is a

Service Form W-8BEN or Form W-8ECI or such other forms, certificates or other
evidence with respect to United States Federal income tax withholding matters

(but shall have no obligation to) elect to assume the obligations of Borrower
thereafter accruing under any or all of the Project Documents; provided that in
no event shall Lender be responsible for any default by Borrower or any other
party occurring prior to any election by Lender to assume such obligations under
such Project Documents.

SECTION 4.1 and the rights granted to Lender hereunder and under SECTION 8.4

Project Documents as provided in SECTION 4.1(B), obligate Lender to assume any
obligations or liability under any of the Project Documents, to expend any money
or incur any expense in connection with any of the Project Documents or to
perform any obligation under any of the Project Documents.

under the Project Documents, diligently enforce its rights under the Project
Documents unless otherwise agreed by Lender, in Lender's reasonable discretion

harmless for, from and against all expenses, loss, claims, damage or liability
which the Indemnitees incur under any of the Project Documents or under or by
reason of the assignment set forth in SECTION 4.1 or by reason of any actual or
alleged obligation or undertaking on Lender's part to perform or discharge any
covenants or agreements contained in any of the Project Documents; provided that
such indemnity shall not extend to expenses, loss, claims, damage or liability
arising from an Indemnitee's gross negligence or willful misconduct or, with
respect to any Project Documents assumed by Lender as provided in SECTION 4.1(B)
relating to the period after the date, if ever, that Lender assumes the
obligations under such Project Documents as provided in SECTION 4.1(B).

repair, and shall not misuse, abuse, allow to deteriorate, waste or destroy the
Personal Property or any part thereof, except for ordinary wear and tear
resulting from normal and expected use in the ordinary course of Borrower's
business, which shall be promptly replaced by Borrower with property of similar
nature and of equal or greater value, unless such Personal Property is obsolete.

     C.   Borrower shall not, without the prior written consent of Lender, which
consent shall not be unreasonably withheld, sell, offer to sell or otherwise
transfer, exchange, hypothecate or dispose of the Personal Property or any
interest therein, unless in the normal course of business the Personal Property

<Page>

                                                                    EXHIBIT 4.13

is being replaced by collateral of similar nature and of equal or greater value,
or such Personal Property is obsolete. If the Personal Property or any part
thereof is sold, transferred, exchanged, or otherwise disposed of (either with
or without the written consent of Lender), the security interest of Lender shall
extend to the proceeds of such sale, transfer, exchange or other disposition
and, if the proceeds thereof are in excess of One Hundred Thousand Dollars
($100,000) individually or in the aggregate, at Lender's written request,
Borrower shall hold such proceeds in a separate account for Lender's benefit and
shall, at Lender's written request, transfer such proceeds into a cash
collateral account with Lender as additional collateral for the Loan.

     D.   The tangible Personal Property shall be kept on or at the Project and
Borrower shall not, without the prior written consent of Lender, which may be
withheld in Lender's good faith sole discretion, remove the Personal Property
therefrom except such portions or items of Personal Property which are consumed
or worn out in ordinary usage, all of which shall be promptly replaced by
Borrower as provided in SECTION 5.2(B).

     E.   Borrower shall immediately notify Lender in writing of any change in
its state of incorporation or organization or in its place of business, any
change in Borrower's name or organizational number or the adoption or change of
any trade name or fictitious business name used by Borrower.

     F.   The Personal Property is not and shall not be used or bought for
personal, family or household purposes.

     G.   Lender may examine and inspect the Personal Property at any reasonable
time, wherever located upon reasonable prior notice to Borrower (except in the
event of an emergency or from and after the occurrence of any Event of Default
under the Loan Documents, or at any time during which an uncured Potential
Default exists under the Loan Documents, in which event prior notice shall not
be required).

     5.3  AFFIXED COLLATERAL.

     The inclusion in SECTION 5.1 of any Personal Property which may now be or
hereafter become affixed or in any manner attached to the Project shall be
without prejudice to any claim at any time made by Lender that such Personal
Property is or has become a part of or an accession to the Project.

     5.4  FURTHER SECURITY AGREEMENTS.

     Borrower agrees to take such actions and, within ten (10) days after
Lender's written request, to execute, deliver and file and/or record such
documents, agreements and financing statements, as may be reasonably necessary
to evidence the security interest set forth in SECTION 5.1, to establish the
priority thereof, to carry out the intent and purpose of this ARTICLE 5 and/or

organizational number or place of business.

than thirty (30) days prior to the expiration date. If Borrower fails to provide
notice of renewal of the Letter of Credit or evidence of renewal as required by
this SECTION 5.5, Borrower's failure shall constitute an Event of Default under
Section 8.1 (A) hereof. The Letter of Credit may be drawn down by Lender in
multiple drawings at Lender's sole discretion. All proceeds from the Letter of
Credit will be applied to pay down the outstanding Loan indebtedness. At such
time as Standard & Poors and Moodys shall have upgraded their Debt Rating for
the Guarantor to BB or Ba2 or higher, as applicable, the face amount of the
Letter of Credit shall be reduced to $1,000,000. In the event that the Debt
Rating for the Guarantor is increased to investment grade or higher by both
rating agencies, then the Letter of Credit shall no longer be required.

fully remedied and cured at Borrower's cost and expense.

                                                                    EXHIBIT 4.13

     7.4  LEASING OF SPACE.

     A.   Unless otherwise approved by Lender in writing in advance (which
approval may be withheld in Lender's good faith sole discretion), the Approved
Lease shall reflect an arms-length transaction at the then current market rate
for comparable space. The Approved Lease shall comply with all applicable Laws,
including, without limitation, all subdivision requirements, if any. Borrower
shall perform all obligations required to be performed by it as landlord under
the Approved Lease. Borrower shall not accept any Prepaid Property Income
(however denominated).

     B.   Borrower shall not enter into, or modify, amend, terminate or accept a
surrender or cancellation of the Approved Lease, or consent to any assignment or
subletting under the Approved Lease, or enter into any other Lease, without
Lender's prior written approval of any sublease, assignment, or other Lease, and
the tenant's financial condition (including, without limitation, financial
statements, operating history and business prospects), which shall not be
unreasonably withheld. Lender's prior written consent shall not be required for
any amendment or modification of the Approved Lease or any other Lease if the
amendment or modification does not alter a Material Lease Provision. Lender's
prior written consent, which may be withheld in Lender's good faith sole
discretion, shall be required if (a) any proposed tenant's operations at, on or
about the Project will or are reasonably likely to at any time involve the use,
generation, storage, handling or disposal of Hazardous Substances, or (b) the
tenant's use of the Project or applicable portion thereof is not consistent with
the use of the remainder of the Project.

     C.   Promptly after the execution of any modification, amendment or
termination of the Approved Lease, or any other Lease previously approved by
Lender, Borrower shall deliver to Lender copies of such modification, amendment
or termination, and all other documents executed in connection therewith,
whether or not Lender's approval is required in connection therewith pursuant to
this SECTION 7.4. In the event that Borrower enters into any other Lease or
executes an assignment or sublease under the terms of the Approved Lease,
Borrower shall promptly prepare and deliver to Lender a rent roll, operating
statements or other leasing information as Lender may from time to time
reasonably request. Borrower shall promptly take such steps as shall be
reasonably necessary to prevent any set-off against rent or other amounts
payable under any Lease including, without limitation, the payment or
reimbursement of any costs incurred or losses suffered which gave rise to the
claim for set-off.

     D.   If requested by Lender with respect to the Approved Lease, Borrower
shall, within twenty (20) days after Lender's written request, execute and
deliver to Lender, and use commercially reasonable efforts to cause the tenant
under any Lease (and any other party to, or guarantor of, such Lease) to execute
and deliver to Lender, a nondisturbance and attornment agreement in form and
substance reasonably satisfactory to Lender. If requested by Lender with respect
to any Lease, Borrower shall, within twenty (20) days after Lender's written
request, execute and deliver, and use commercially reasonable efforts to cause
the tenant under such Lease to execute and deliver, to Lender, an estoppel
certificate in form and substance reasonably satisfactory to Lender.

     E.   As used herein, "MATERIAL LEASE PROVISION" means a provision which
materially increases the landlord's obligations under any Lease, including, but
not limited to the Approved Lease, or any other Lease, which provides the tenant
with material rights or recourse against the landlord or with the right to
terminate the Lease, or which adversely affects Lender's security in the Lease.
Without limiting the generality of the foregoing, each of the following shall
constitute a Material Lease Provision: (i) any provision which affects Lender's
rights with respect to the Lease, which affects the relative priority of the
Lease and the Security Instrument without Lender's consent, or which requires
Lender to agree to or provide any nondisturbance agreement to the tenant; (ii)
the grant of an option, right of first offer or refusal or other right to
purchase all or any portion of the Project, (iii) the grant of an option, right
of first offer or refusal or other right to lease any additional space in the
Project at a rent less than market rent, (iv) the grant of any early termination
option (except in the event of a major casualty or substantial condemnation),
(v) any provision which provides for the application of insurance or
condemnation proceeds in a manner contrary to the Loan Documents, (vi) any
reduction in the rent payable under such Lease, (vii) the grant of any offsets,
or the agreement for the payment of any amounts by the landlord, other than
tenant improvement allowances at then current market levels, if such offset or
payment

                                       19
<Page>

                                                                    EXHIBIT 4.13

obligation would be applicable to any subsequent owner of the Project,
including, without limitation any owner succeeding to the landlord's interest by
foreclosure or a deed in lieu or in aid thereof, (viii) a limit to the expense
reimbursements due from the tenant for increases in taxes or expenses, (ix) an
environmental, hazardous substance or other indemnification binding on the
landlord that would be applicable to any subsequent owner of the Project,
including, without limitation, any owner succeeding to landlord's interest by
foreclosure or a deed in lieu or in aid thereof, (x) any direct or indirect
restriction or limitation in favor of the tenant on the use or leasing of any
portion of the Project not covered by such Lease, including, without limitation,
any provision entitling the tenant to the exclusive operation of any business in
the Project, or (xi) any direct or indirect restriction or limitation in favor
of the tenant on the use or leasing of any property other than the Project,
including, without limitation, any provision entitling the tenant to the
exclusive operation of any business within a specified radius of the Project.

     F.   Prior to the commencement of any work at the Project by or on behalf
of any tenant under any Lease (or, if Borrower does not have knowledge of such
work prior to the commencement thereof, as soon as Borrower learns of such
work), Borrower shall post and record, in compliance with applicable law,
notices of non-responsibility, or the local equivalent thereof, with respect to
such tenant work.

     G.   Without limiting the terms of the Assignment of Rents, within ten (10)
days after Lender's written demand at any time (after and during the continuance
of an Event of Default under any of the Loan Documents), Borrower shall deliver
to Lender any or all security deposits then or thereafter held by Borrower, if
any. If any of such security deposits are in the form of letter(s) of credit,
Borrower shall deliver to Lender the original letter of credit, together with
original transfer documents in the form required by such letter of credit,
transferring such letter of credit to Lender. All such security deposits
delivered to Lender shall be held by Lender in accordance with the terms of the
applicable Lease and any then remaining security deposits held by Lender upon
the payment in full of the Loan and all amounts owing to Lender under the Loan
Documents shall be delivered and re-assigned, if applicable, to Borrower. Within
ten (10) days after Lender's written request, Borrower and Guarantor shall
execute and deliver to Lender such documents as may be reasonably requested by
Lender in connection with the delivery of such security deposits to Lender.

     H.   Immediately upon the payment of any Lease Termination Payments,
Borrower shall deliver such Lease Termination Payments to Lender. Such Lease
Termination Payments shall be deposited into a cash collateral account and
pledged to Lender as additional collateral for the Loan. Such funds shall be
disbursed by Lender, subject to such terms and conditions as may be reasonably
imposed by Lender, to pay such tenant improvement costs and leasing commissions
for the applicable vacated space in the Project as may be approved by Lender,
which approval shall not be unreasonably withheld. Within ten (10) days after
Lender's written request, Borrower and Guarantor shall execute and deliver to
Lender such documents as may be reasonably requested by Lender in connection
with the delivery of any Lease Termination Payments to Lender, including,
without limitation, a pledge agreement setting forth the terms under which funds
in such cash collateral account shall be disbursed.

     7.5  ENVIRONMENTAL MATTERS.

     A.   Borrower shall, at its own expense, comply and cause all persons
entering the Project to comply with all Environmental Laws applicable thereto
and Borrower shall not use, store, process, manufacture, transport, dispose or
release any Hazardous Substances on, in or adjacent to any part of the Project
or permit any of the foregoing to occur except as used in the ordinary course of
Borrower's or Guarantor's or one of their Affiliate's business which Hazardous
Substance shall be used and stored in compliance with Environmental Laws.
Borrower shall immediately advise Lender in writing of any (i) discovery of
Hazardous Substances on, at, from or under the Project or any portion thereof in
violation of Environmental Laws; or (ii) any claim, action or order threatened
or instituted by any third party (including, without limitation, any
Governmental Agency) against the Project or Borrower relating to damages, cost
recovery, liability, loss or injury resulting from any Hazardous Substances,
including those used or stored in the ordinary course of Borrower's, Guarantor's
or one of their Affiliate's business. Borrower shall provide Lender with copies
of all communications with any third party (including, without

                                       20
<Page>

                                                                    EXHIBIT 4.13

limitation, any Governmental Agency) relating to any Environmental Law or any
claim, action, notice of violation, inquiry, investigation or order relating to
Hazardous Substances at, on, under or in the Project or any portion thereof.
Borrower shall promptly and diligently remediate any Hazardous Substances
contamination at, under, from or attributable by joint and several liability to
the Project to a level required by Environmental Laws. Without limiting the
foregoing, if any remedial action is required by any Environmental Laws,
Borrower shall immediately notify Lender of such situation and shall prepare a
written plan setting forth a description of such situation (and all
environmental reports relating thereto) and the remedial action that Borrower
proposes to implement in connection therewith. Borrower shall, at its own
expense, thereafter diligently and continuously pursue the remediation of the
condition necessary to bring the Project into compliance with this SECTION
7.5(A) and shall, at its own expense, promptly cause all liens or encumbrances
against the Project in connection therewith to be removed and satisfied.

     B.   Lender shall have the right at any time to retain a professional
environmental consultant to conduct tests and investigations of the Project
(including, without limitation, ground water and soils testing) with respect to
Hazardous Substances or the Project's compliance with Environmental Laws.
Borrower hereby grants to Lender, its agents, employees, consultants and
contractors, an irrevocable license and authorization to enter upon and inspect
the Project and to conduct such tests and investigations on the Project or any
portion thereof as Lender, in its sole discretion, determines necessary. Such
tests shall be conducted at reasonable times, upon reasonable prior notice and
so as not to unreasonably interfere with the tenant's business. Such tests and
investigations shall be at Lender's expense unless (i) a breach of the
provisions of SECTION 6.10 or SECTION 7.4(B) has occurred, or a breach of, or
release or contamination governed by, this SECTION 7.5 has in fact occurred, or
(iii) an Event of Default has occurred under any of the Loan Documents or an
uncured Potential Default exists under any of the Loan Documents. Borrower
acknowledges and agrees that, as between it and Lender, only Borrower owns and
operates the Project and only Borrower has the responsibility for compliance
with this SECTION 7.5 and neither Lender's enforcement of, or failure to
enforce, any of the provisions of SECTION 7.5 shall be deemed to affect the
obligations or provisions of this SECTION 7.5.

     C.   To the fullest extent permitted by law, Borrower hereby indemnifies
and agrees to defend, and hold harmless the Indemnitees for, from and against
any and all loss, claim, damage or liability of any kind or nature and from any
suits, actions, claims or demands, including without limitation, all amounts
described in SECTION 7.5(D), arising directly or indirectly, in whole or in
part, out of (i) the existence or alleged existence of any Hazardous Substances
at, on, under, from or in the Project or any portion thereof, (ii) the removal
of or failure to remove any Hazardous Substances from the Project or any portion
thereof or from neighboring property, including, without limitation, from the
groundwater of the Project or any neighboring property (in the case of
neighboring property, only to the extent caused by Borrower or otherwise
migrating from the Project), (iii) any activity involving Hazardous Substances
with respect to the Project carried on or undertaken on or off the Project, (iv)
any residual contamination on or under the Project or on or under any
neighboring property (in the case of neighboring property, only to the extent
caused by Borrower or otherwise migrating from the Project), or (v) any
contamination of any property or natural resources arising by, through or under
Borrower or any tenant of Borrower in connection with any activity involving
Hazardous Substances, in each case whether prior to or during the term of the
Loan, and whether by Borrower or any other party, provided that such indemnity
shall not extend to damage or liability incurred by an Indemnitee to the extent
such damage or liability is caused directly by such Indemnitee's gross
negligence or willful misconduct. Upon receiving knowledge of any suit, action,
claim or demand asserted by a third party that Lender believes is covered by
this indemnity, Lender shall give Borrower written notice of the matter and an
opportunity to defend it, at Borrower's sole cost and expense, with legal
counsel reasonably satisfactory to Lender. Lender may also require Borrower to
so defend the matter. The obligations of Borrower under this SECTION 7.5(C) are,
without limitation, intended to operate as a binding valid indemnity agreement
under 42 U.S.C. Section 9607(e)(1) and shall survive the closing of the Loan and
the repayment of the Loan and the satisfaction of all other Secured Obligations.

     D.   The indemnity set forth in SECTION 7.5(C) shall include, without
limitation, (i) loss, claims, damage or liability for, or arising from, personal
injury and property damage, including, without limitation, diminution in
marketability or value of property, (ii) compensation for lost wages, rents,
business income, profits or other economic loss, (iii) all consequential
damages; (iv) all damages to any natural resources

and the environment, the costs of any repair, clean up, response cost, or

the investigation, preparation and implementation of any closure, remedial or
other required plans; and (v) all costs and expenses incurred in connection with
any of the foregoing, including, without limitation, reasonable attorneys' fees

     7.6  INSURANCE REQUIREMENTS.

     A.   Borrower shall procure and maintain, or cause to be procured and
maintained, at all times until the repayment of the Loan and the satisfaction of
the Secured Obligations, policies of insurance in form and amounts as set forth
in Section 7.6B and issued by companies qualified to do business in the state
where the Project is located and having a Best's rating of at least A:VIII. All
policies shall expressly protect Lender's interest as required by Lender. If

Borrower shall pay all amounts expended by Lender for such insurance, together
with interest thereon at the Default Interest Rate, within ten (10) days after
written demand by Lender. In the event of any foreclosure of the Security
Instrument or a deed in lieu or in aid thereof or other transfer of title to the
Project in extinguishment in whole or in part of the Secured Obligations, all
right, title and interest of Borrower in and to all proceeds payable under the
insurance policies required by this SECTION 7.6 and then in force shall vest in

               (3)  Borrower's property insurance coverage shall include,

period of not less than eighteen (18) months from the date of casualty or loss,
or (b) until that date on which the Project is fully reconstructed or repaired,

broad in coverage as the primary policy and satisfy all the requirements of this
SECTION 7.6. Lender shall be named as an additional insured on the liability
insurance policy or policies by endorsement CG 20 26 11 85 or equivalent

policies: (i) shall have a deductible of (a) not more than Fifty Thousand
Dollars ($50,000) per occurrence with respect to the commercial general
liability insurance and (b) not more than One Hundred Thousand Dollars
($100,000) with respect to any other insurance; (ii) with respect to the

in favor of, and in form reasonably satisfactory to, Lender (providing, without
limitation, that Lender's right of recovery shall not be prejudiced or impaired
by any act, error or omission (whether negligent, willful or otherwise) of
Borrower, any other insured or any other person or entity); (iii) shall provide

                                       23
<Page>

                                                                    EXHIBIT 4.13

premiums); (iv) shall include a waiver of subrogation as to Lender with respect
to the Property Insurance and provide that such waiver shall not invalidate or
prejudice the coverage available to Borrower or Lender; (v) may be in the form
of blanket policies, in amount, form and content reasonably satisfactory to
Lender, provided that any such blanket policy or policies shall specify the
address of the Project and the Property, the portion of the total coverage of
such blanket policies that is allocated to the Property and the Project, and any
sublimits in such blanket policies applicable to the Property and the Project,
and provided further that all other requirements of this SECTION 7.6 are
satisfied; (vi) shall provide that the coverage afforded is primary and that any
other insurance available to Borrower or Lender is secondary, excess and
noncontributing; (vii) shall provide for severability of interests (separation
of insureds) such that Lender's rights under the policies are separate from and
independent of Borrower's; and (viii) shall contain no insured vs. insured
exclusions. Borrower shall not obtain or maintain separate insurance or
additional insurance concurrent in form or contributing in the event of loss
with that required to be maintained hereunder without the prior written consent
of Lender, which consent shall not be unreasonably withheld, provided that such
policies satisfy all of the requirements of this SECTION 7.6.

     D.   Notwithstanding anything to the contrary contained in the Loan
Documents, Borrower waives any and all right of action or recovery against
Lender, and its Affiliates, predecessors, successors, assigns, directors,
officers, employees, agents and representatives, for any loss, liability, claim,
expense, injury or damage, including without limitation to, or arising out of or
relating directly or indirectly to, the Project, Collateral, Borrower,
Borrower's property, or the property of others under Borrower's control, to the
extent such loss, liability, claim, expense, injury or damage is insured against
or required to be insured against under this SECTION 7.6 or is coverable by
insurance.

     E.   At Lender's election at any time not more frequently than once per
calendar year, the Replacement Cost amount of Borrower's property insurance
shall be adjusted. In connection therewith, Borrower shall, at its sole expense,
provide at the written request of Lender evidence reasonably satisfactory to
Lender of the Replacement Cost of the Project. Such evidence may be in the form
of an insurance appraisal or valuation report prepared by an insurance company,
appraiser or other consultant reasonably acceptable to Lender.

     F.   Borrower shall, at Borrower's sole expense, comply with all
requirements, guidelines, rules and orders and similar mandates and directives
relating to the Project and the Property imposed by any insurer and shall not
cause or permit any condition to exist in, at or about Project or the Property
which would invalidate or impair the insurance coverage required by this SECTION
7.6, which would result in a material increase in hazard or which would
constitute grounds for cancellation or non-renewal of any policy referred to in
this SECTION 7.6.

     G.   Delivery to Lender of the certificates and endorsements referred to in
this SECTION 7.6 shall constitute an assignment of all proceeds payable under
such insurance as relating to the Project or the Property by Borrower to Lender
as further security for the Secured Obligations.

     H. Notwithstanding any receipt, review, approval or consent to any
insurance referred in this SECTION 7.6, Lender shall incur no liability as a
result of the insolvency of any insurer, failure of any insurer to perform,
deductibles, inadequacy of limits of any policy, limitations or exclusions from
coverage or failure of any insurer to pay any claim, even where Lender has
caused insurance to be placed with an insurer after failure by Borrower to
comply with the requirements of this SECTION 7.6.

     I.   The insurance requirements set forth in this SECTION 7.6 are
independent of Borrower's indemnification obligations and other obligations to
Lender hereunder and under the other Loan Documents, and shall not be construed
or interpreted to restrict, limit or modify Borrower's indemnification
obligations or any other obligations to Lender hereunder or under any of the
Loan Documents.

     7.7  NOTICE OF PROCEEDING.

     Borrower will promptly notify Lender of any notice of violation, action,
suit, proceeding or arbitration (including, without limitation, any judicial or
nonjudicial foreclosure proceeding, any voluntary or

                                       24

     7.8  FINANCIAL AND OTHER INFORMATION.

     Borrower shall maintain full and complete books of account and other
records reflecting the results of operations of the Project in accordance with
the Financial Reporting Method. Borrower shall furnish or cause to be furnished

and the Project and the other Collateral as Lender may reasonably request from
time to time. Lender shall also have access to such books and records and
Borrower's corporate or organizational books, during regular business hours and
upon reasonable advance notice to Borrower, and shall have the right to make
copies thereof or extracts therefrom and to discuss the finances and accounts of
Borrower with Borrower, its partners or members, as applicable, and its
independent public accountants, all as Lender may reasonably request. Without
limiting the generality of the foregoing, Borrower shall furnish to Lender,
without prior request or demand:

     A.   ENTITY FINANCIAL STATEMENTS. If Borrower and/or any Principal Party
is not a natural person or a trust, on or before each Financial Statement
Delivery Date, Borrower shall provide Lender with financial statements

otherwise in form reasonably acceptable to Lender, and (ii) contain comparative

provide Lender with a written certification, in form reasonably satisfactory to
Lender, that there has been no material adverse change in the financial
condition of Borrower and each such Principal Party from the financial

been a material adverse change, explaining such material adverse change in
reasonable detail).

     B.   INTENTIONALLY DELETED.

     D.   FAILURE TO DELIVER FINANCIAL STATEMENTS. Without limiting any of
Lender's rights or remedies in the event of any failure by Borrower to comply
with the provisions of this SECTION 7.8, if Borrower fails to deliver to Lender
any of the financial statements or other information required herein on or
before the applicable date required in this SECTION 7.8 (the "Information
Delivery Date"), and if Borrower continues to fail to deliver any such financial
statements or other information within fifteen (15) days after written notice
from Lender given on or after the Information Delivery Date, then, commencing on
the first day after the Information Delivery Date, the Variable Interest Rate
(as defined in the Note) shall be increased by one-half percent (.50%) until
such time as Borrower has delivered all of the financial statements or other
information required to be delivered by Borrower pursuant to, and in the form
required by, this SECTION 7.8. In addition to such increase in the Variable
Interest Rate during the Amortization Period, the Monthly Installments shall be
adjusted effective with the Monthly Installment due immediately following the
Information Delivery Date to reflect such increase. Once Borrower has delivered
all of the

                                                                    EXHIBIT 4.13

financial statements and other information required to be delivered by Borrower

the Monthly Installment due immediately thereafter.

     7.9  OTHER CONTRACTUAL OBLIGATIONS.

     Borrower shall perform all of its obligations under (a) any Contractual
Obligation if the failure to perform any such obligation would have a material
adverse effect on Borrower's ability to repay the Loan or to perform any of its
obligations under any of the Loan Documents or under the Environmental
Indemnity, and (b) all Permitted Indebtedness.

     7.10 FURTHER ASSURANCES.

     Borrower shall execute and deliver, and shall cause Guarantor to execute
and deliver, from time to time, within ten (10) days after written any request
by Lender, any and all instruments, agreements and documents, and shall take
such other action, as may be reasonably necessary or desirable in the opinion of
Lender to maintain, perfect or insure Lender's security provided for herein and
in the other Loan Documents, including, without limitation, the execution of
UCC-1 renewal statements, the execution of such amendments to the Security
Instrument and the other Loan Documents and the delivery of such endorsements to
the Title Policy, all as Lender shall reasonably require, and shall pay all
reasonable fees and expenses (including, without limitation, reasonable
attorney's fees and costs) related thereto.

     7.11 EQUITY DISTRIBUTIONS.

     Borrower shall not make any direct or indirect Equity Distributions (a)
from and after the occurrence of an Event of Default under any of the Loan

the Loan Documents, including, without limitation, at any time during which any
Impound Expenses are delinquent.

     7.12 ENTITY REQUIREMENTS.

     Borrower (a) shall not engage or be authorized to engage in any business
unrelated to the Project, (b) shall not have assets other than those related to
its interest in the Project, (c) shall not have any Indebtedness other than the
Permitted Indebtedness, (d) shall have its own books and records separate and

members, as applicable. Borrower and the Principal Parties shall maintain and
preserve their existence and all rights and franchises material to their
respective businesses and shall be, at all times, validly existing and in good
standing in the state of their formation. Borrower shall be, at all times,

Without limiting the provisions of SECTION 1.10 of the Security Instrument,
neither Borrower nor any of the Principal Parties shall amend or modify any of
their respective Formation Documents without Lender's prior written consent,
which shall not be unreasonably withheld unless such amendment or modification
relates to a Transfer (in which event Lender's consent may be withheld in
Lender's good faith sole discretion). Promptly after Lender's written request
from time to time, but not more frequently than once in any calendar year,
Borrower shall deliver to Lender evidence reasonably satisfactory to Lender that

     7.13 MANAGEMENT OF THE PROJECT.

     The Project shall be managed by Borrower or an Affiliate of Borrower
approved by Lender for so long as no Event of Default has occurred under the
Loan Documents and so long as Borrower or such Affiliate is managing the Project
in a first class manner. In the event that Borrower hires a Project property
manager, such property manager shall not be entitled to payment of any fees or
costs for services rendered for the benefit of Borrower until such time as the
property manager executes a written agreement. Such written agreement shall be
approved in advance in writing by Lender if (a) any Event of Default has
occurred under any of the Loan Documents or an uncured Potential Default exists
under any of the Loan Documents or (b) such agreement is not terminable with or
without cause and without penalty, upon not more than thirty (30) days' notice
to the manager thereunder. In no event shall any manager be removed or replaced
or any management agreement modified, amended, or terminated without the prior
written consent of Lender if any Event of Default has occurred under any of the
Loan Documents or an uncured Potential Default exists under any of the Loan
Documents. At Lender's election, within ten (10) days after Lender's written
request, Borrower and any such manager of the Project shall execute and deliver
to Lender an assignment of such management agreement in form reasonably
satisfactory to Lender and, at Lender's election in its sole discretion,
allowing Lender either to terminate such management agreement immediately upon
the transfer of title to the Project as a result of the exercise of its remedies
under the Loan Documents, or to keep such management agreement in effect after
such transfer of title. Lender's consent and approval under this SECTION 7.13
shall not be unreasonably withheld.

     7.14 COMPLIANCE WITH GOVERNMENTAL PROHIBITIONS.

     No portion of the Loan proceeds will be used, disbursed or distributed by
Borrower or any Principal Party for any purpose, or to any Person, in violation
of any Law including, without limitation, any of the Terrorism Laws. Borrower
shall provide Lender with immediate written notice (a) of any failure of any of
the representations and warranties set forth in SECTION 6.14 of this Agreement
or in SECTION 4(M) of the Guaranty to be true, correct and complete in all
respects at any time, or (b) if Borrower obtains knowledge that Borrower, any of
the Principal Parties, or any holder at any time of any direct or indirect
equitable, legal or beneficial interest in Borrower or any of the Principal
Parties is the subject of any of the Terrorism Laws. Borrower shall immediately
and diligently take, or cause to be immediately and diligently taken, all
necessary action to comply with all Terrorism Laws and to cause the
representations and warranties set forth in SECTION 6.14 of this Agreement and
in SECTION 4(M) of the Guaranty to be true, correct and complete in all
respects.

     7.15 BORROWER ESTOPPEL CERTIFICATES.

     A.   Within ten (10) days after Lender's written request from time to time,
but not more frequently than once in any calendar year, Borrower shall execute
and deliver, and shall cause Guarantor to execute and deliver to Lender, an
estoppel certificate in the form reasonably requested by Lender, stating that
the Loan Documents and the Environmental Indemnity are in full force and effect,
the amount of Loan proceeds advanced by Lender, and such other matters relating
to the Loan and the Loan Documents as may be reasonably requested by Lender.

     8.1  EVENTS OF DEFAULT.

     A.   EVENTS OF DEFAULT ON NOTICE TO BORROWER. The occurrence of any of the
following events shall constitute an Event of Default under this Agreement and
the other Loan Documents upon written notice by Lender to Borrower given at any
time on or after the occurrence of any such event; provided that upon such
notice from Lender, such Event of Default shall be deemed to have occurred as of
the occurrence of such event, irrespective of the date of such notice; and
provided further that Lender's

                                                                    EXHIBIT 4.13

giving of or failure to give such notice shall not affect, in any manner
whatsoever, the imposition of any late charge or interest at the Default
Interest Rate pursuant to the provisions of the Note or the other Loan
Documents:

          (i)    FAILURE TO MAKE PAYMENTS WHEN DUE. Borrower's or Guarantor's
failure to pay any principal, interest or other monies due under this Agreement

to perform or comply with any term, obligation or condition contained in this
Agreement or any of the other Loan Documents, other than those terms,
obligations and conditions otherwise referred to in this SECTION 8.1(A) and
other than Borrower's obligations under SECTION 1.10 of the Security Instrument,
within thirty (30) days after the delivery of written notice from Lender of such
failure; provided that if such default is not reasonably capable of being cured
(without taking into account financial capability) within such thirty (30) day
period, such failure shall not constitute an Event of Default so long as
Borrower or Guarantor, as applicable, commences the cure of such default within
such thirty (30) day period and diligently prosecutes such cure to completion
within one hundred eighty (180) days after such written notice from Lender.

          (iii)  BREACH OF WARRANTY. Any representation, warranty, certification
or other statement made by Borrower or any of the Principal
Parties herein or in any Application Information, or in any other Loan Document
or in any statement or certificate at any time given by Borrower or any of the
Principal Parties to Lender in writing in connection with the Loan shall be
materially false or misleading.

          (iv)   LIEN PRIORITY. Lender fails to have a legal, valid, binding and
enforceable first priority Lien on the Project or any portion thereof or on any
material portion of the Personal Property or other Collateral.

          (v)    UNAPPROVED TRANSFERS. Any Transfer which requires Lender's
consent under SECTION 1.10 of the Security Instrument occurs without Lender's
prior written consent in accordance with SECTION 1.10 of the Security
Instrument.

          (vi)   FAILURE TO MAINTAIN INSURANCE/FAILURE OF INSURANCE COVERAGE TO
REMAIN IN EFFECT. Borrower fails to maintain or cause to be maintained the
insurance coverage required by SECTION 7.6, or there is any rescission or
cancellation of any insurance required by SECTION 7.6, or any carrier of any
insurance required by SECTION 7.6 denies coverage as a result of any act or
omission of Borrower, any Limited Recourse Party or any Exculpated Person, or
any of their agents.

          (vii)  OTHER LIENS. Without limiting the provisions of SECTION 7.1
of this Agreement or SECTION 1.10 of the Security Instrument, Borrower defaults
under any Lien (other than the Liens created by the Loan Documents) or
foreclosure or other proceedings are commenced to enforce any Lien (other than
the Liens created by the Loan Documents).

          (viii) MATERIAL LITIGATION. The commencement or filing of any action,
suit, proceeding or arbitration against or involving Borrower or any of the
Principal Parties which, if determined adversely to Borrower or such Principal
Party, would not be covered in whole or in part by insurance and for which
Borrower or such Principal Party would have liability in excess of Five Hundred
Thousand Dollars ($500,000).

          (ix)   GOVERNMENTAL PROHIBITIONS. Borrower's or Guarantor's failure to
perform or comply with any of the terms, obligations or provisions of SECTION

employer identification number is the Tax Identification Number; (c) Borrower's
principal place of business is at the address set forth in SECTION 9.10, and (d)
Borrower is qualified to do business in the Governing State. Lender may disclose
the contents of this SECTION 9.1 to the Internal Revenue Service or any other
Governmental Agency and Borrower acknowledges that any false statement contained
herein could be punished by fine, imprisonment or both. Within ten (10) days
after Lender's written request, Borrower shall execute and deliver to Lender
further certificates, which shall be signed under penalty of perjury, as Lender
shall reasonably require in connection with the certifications set forth herein.

the Loan Documents and/or the Environmental Indemnity, or any other interest
herein or in the Note to any Person, all without notice to or the consent of
Borrower. To the extent of any such assignment, Lender shall be relieved of its
obligations with respect to the Loan and the assignee shall have the same
rights, benefits and obligations as it would if it were Lender hereunder and a
holder of the Note. Lender may furnish any information (including, without
limitation, financial information) concerning the Project, the Collateral,
Borrower, the Principal Parties and any of their assets to third parties from

Collateral or any portion thereof or any interest therein. Such costs and
expenses shall include, without limitation, Lender's reasonable attorneys' fees
and costs, including without limitation reasonable attorneys' fees and costs
incurred by Lender in connection with any insolvency, bankruptcy,
reorganization, arrangement or other similar proceedings involving Borrower or
any of the Principal Parties which in any way affect the exercise by Lender of
its rights and remedies hereunder, under any of the other Loan Documents, at law
or in equity.

paid without notice, demand, counterclaim, setoff, deduction or defense and
without abatement, suspension, deferment, diminution or reduction, and the

     9.7  APPROVALS, AMENDMENTS AND WAIVERS.

this Agreement and the other Loan Documents must be in writing to be effective.
This Agreement and the other Loan Documents may only be modified in writing
signed by all of the parties hereto or thereto or their respective successors
and assigns. No waiver of any provision of this Agreement or of any of the other
Loan Documents, or consent to any departure by Borrower therefrom, shall in any
event be effective without the written agreement of Lender. Any waiver or
consent shall be effective only in the specific instance and for the specific
purpose for which it was given. Except as expressly required by the terms of the
Loan Documents, no notice to or demand on Borrower or any of the Principal
Parties in any case shall entitle Borrower or any of the Principal Parties to

     The submission of this Agreement, any of the other Loan Documents or the
Environmental Indemnity to Borrower, Guarantor or any of the other Signature
Parties or their agents or attorneys for review or signature does not constitute
a commitment by Lender to make the Loan to Borrower, and the Loan Documents and
the Environmental Indemnity shall have no binding force or effect unless and

or privilege or be construed to be a waiver of any default or acquiescence
therein, nor shall any single or partial exercise of any such power, right or
privilege preclude other or further exercise thereof or of any other right,
power or privilege. All rights and remedies existing under this Agreement and
the other Loan Documents are separate, distinct and cumulative to, and not
exclusive of, any rights or remedies otherwise available at law or in equity. No
act of Lender under any of the Loan Documents shall be construed as an election
to proceed under any one provision to the exclusion of any other provision,

Loan Documents shall be deemed to have been disbursed to Borrower and shall be
secured by the Loan Documents.

     9.15 SEVERABILITY.

     If any term of this Agreement or any of the other Loan Documents or the
application thereof to any Person or circumstances, shall, to any extent, be
invalid or unenforceable, the remainder of this Agreement or other Loan Document

     Where the identity of the parties to this Agreement or any of the other
Loan Documents or the circumstances make it appropriate, the masculine gender
includes the feminine and/or neuter, and the singular number includes the
plural. Article and Section headings in this Agreement and the other Loan
Documents are included for convenience of reference only and shall not
constitute a part of this Agreement or such other Loan Documents for any other
purpose or be given any substantive effect. The recitals to this Agreement and
to each of the other Loan Documents are incorporated herein and therein and made
a part hereof and thereof. All exhibits to each of the Loan Documents shall
constitute a part of the applicable Loan Documents. Borrower and Lender have
each had an opportunity to review and negotiate the terms of this Agreement and
the other Loan Documents; accordingly, the rule requiring that language be
construed against drafting party shall not be applicable to this Agreement or
the other Loan Documents.

     9.17 APPLICABLE LAW.

     This Agreement and the other Loan Documents shall be governed by, and
construed and enforced in accordance with, the laws of the Governing State.

     9.18 SUCCESSORS AND ASSIGNS.

parties hereto and their respective successors and assigns. Borrower's rights
and obligations or any interest hereunder or under any of the other Loan
Documents may not be assigned, including, without limitation, assigned for

discretion and without any obligation, after the occurrence of an Event of
Default, Lender shall not be liable to any contractor, subcontractor, supplier,
laborer, architect, engineer or any other party for services performed or
materials supplied in connection with the Project. Lender shall not be liable
for any debts or claims accruing in favor of any such parties against Borrower
or others or against the Property or the Project. No disbursement of Loan
proceeds directly to any contractor, subcontractor, supplier, laborer,
architect, engineer or any other party for services performed or materials
supplied shall create, or shall be deemed or construed to create, any
third-party beneficiary status in favor of such party or recognition of the same
by Lender. Borrower is not and shall not be an agent of Lender for any purpose.
Lender is not a joint venture partner with Borrower, Guarantor or any of the

applicable document to physically form one document, which may be recorded if
applicable.

understanding between Borrower and Lender relative to the Loan and the same
supersede all prior agreements and understandings relating to the subject matter
