extent of an actual conflict or a potential conflict.  The Lessee and each
Indemnified Person agree to give each other prompt written notice of any Claim
hereby indemnified against but the giving of any such notice by an Indemnified
Person shall not be a condition to the Lessee's obligations under this Section
12.1, except to the extent failure to give such notice materially prejudices
Lessee's rights hereunder or with respect to the defense or settlement of such
Claim.  After an Indemnified Person has been fully indemnified for a Claim
pursuant to this Section 12.1, and so long as no Lease Event of Default shall
have occurred and be continuing, the Lessee shall be

                                                                              27

subrogated to any right of such Indemnified Person with respect to such Claim.
None of the Indemnified Persons shall settle a Claim without the prior written
consent of the Lessee, which consent shall not be unreasonably withheld or
delayed.

          12.2  General Tax Indemnity.  (a)  The Lessee shall pay and assume
liability for, and does hereby agree to indemnify, protect and defend the
Equipment and all Tax Indemnitees, and hold them harmless against, all
Impositions on an After Tax Basis.

          (b) Provided that no Default or Event of Default has occurred and is
continuing, if any Tax Indemnitee obtains a refund or a reduction in a liability
(but only if such reduction relates to a Tax not otherwise indemnifiable
hereunder and has not been taken into account in determining the amount of a
payment on an After Tax Basis) as a result of any Imposition paid or reimbursed
by the Lessee (in whole or in part), such Tax Indemnitee shall promptly pay to
the Lessee the lesser of (x) the amount of such refund or reduction in liability
and (y) the amount previously so paid or advanced by the Lessee, in each case
net of reasonable expenses not already paid or reimbursed by the Lessee.

          (c)(i)  Subject to the terms of Section 12.2(g), the Lessee shall pay
or cause to be paid all Impositions directly to the taxing authorities where
feasible and otherwise to the Tax Indemnitee, as appropriate, and the Lessee
shall at its own expense, upon such Tax Indemnitee's reasonable request, furnish
to such Tax Indemnitee copies of official receipts or other satisfactory proof
evidencing such payment.

          (ii) In the case of Impositions for which no contest is conducted
pursuant to Section 12.2(g) and which the Lessee pays directly to the taxing
authorities, the Lessee shall pay such Impositions prior to the latest time
permitted by the relevant taxing authority for timely payment.  In the case of
Impositions for which the Lessee reimburses a Tax Indemnitee, the Lessee shall
do so within twenty (20) days after receipt by the Lessee of demand by such Tax
Indemnitee describing in reasonable detail the nature of the Imposition and the
basis for the demand (including the computation of the amount payable), but in
no event shall the Lessee be required to pay such reimbursement prior to 15 days
before the latest time permitted by the relevant taxing authority for timely
payment.  In the case of Impositions for which a contest is conducted pursuant
to Section 12.2(g), the Lessee shall pay such Impositions or reimburse such Tax
Indemnitee for such Impositions, to the extent not previously paid or reimbursed
pursuant to subsection (a), prior to the latest time permitted by the relevant
taxing authority for timely payment after conclusion of all contests under
Section 12.2(g).

         (iii)  Impositions imposed with respect to a piece of Equipment for a
billing period during which the Lease expires or terminates with respect to such
Equipment (unless the Lessee has
<PAGE>

                                                                              28

exercised the Purchase Option with respect to the Equipment) shall be adjusted
and prorated on a daily basis between the Lessee and the Lessor, whether or not
such Imposition is imposed before or after such expiration or termination and
each party shall pay or reimburse the other for each party's pro rata share
thereof.

          (iv) At the Lessee's request, the amount of any indemnification
payment by the Lessee pursuant to subsection (a) shall be verified and certified
by an independent public accounting firm mutually acceptable to the Lessee and
the Tax Indemnitee.  The fees and expenses of such independent public accounting
firm shall be paid by the Lessee unless such verification shall result in an
adjustment in the Lessee's favor of 10% or more of the payment as computed by
such Tax Indemnitee, in which case such fee shall be paid by such Tax
Indemnitee.

          (d)(i)  The Lessee shall be responsible for preparing and filing any
real and personal property or ad valorem tax returns in respect of the
Equipment.  In case any other report or tax return shall be required to be made
with respect to any obligations of the Lessee under or arising out of subsection
(a) and of which the Lessee has knowledge, the Lessee, at its sole cost and
expense, shall notify the relevant Tax Indemnitee of such requirement and
(except if such Tax Indemnitee notifies the Lessee that such Person intends to
file such report or return) (A) to the extent required or permitted by and
consistent with Legal Requirements, make and file in its own name such return,
statement or report; and (B) in the case of any other such return, statement or
report required to be made in the name of such Tax Indemnitee, advise such Tax
Indemnitee of such fact and prepare such return, statement or report for filing
by such Tax Indemnitee or, where such return, statement or report shall be
required to reflect items in addition to any obligations of the Lessee under or
arising out of subsection (a), provide such Tax Indemnitee at the Lessee's
expense with information sufficient to permit such return, statement or report
to be properly made with respect to any obligations of the Lessee under or
arising out of subsection (a).  Such Tax Indemnitee shall, upon the Lessee's
request and at the Lessee's expense, provide any data maintained by such Tax
Indemnitee (and not otherwise within the control of the Lessee) with respect to
the Equipment which the Lessee may reasonably require to prepare any required
tax returns or reports;

          (e) If as a result of the payment or reimbursement by the Lessee of
any expenses of a Tax Indemnitee or the payment of any Transaction Expenses
incurred in connection with the transactions contemplated by the Operative
Agreements, any Tax Indemnitee, shall suffer a net increase in any federal,
state or local income tax liability, the Lessee shall indemnify such Tax
Indemnitees (without duplication of any indemnification required by subsection
(a)) on an After Tax Basis for the amount of such increase.  The calculation of
any such net increase shall take into account any current or future tax savings
realized or reasonably expected to be realized by such Tax Indemnitees, in
respect thereof, as well as any interest, penalties and additions to tax payable
by such Tax Indemnitees, in respect thereof;
<PAGE>

                                                                              29

          (f) As between the Lessee and the Lessor, the Lessee shall be
responsible for, and the Lessee shall indemnify and hold harmless the Trust
Company in its individual capacity and as the Lessor (without duplication of any
indemnification required by subsection (a)) on an After Tax Basis against, any
obligation for United States withholding taxes imposed in respect of the
interest payable on the Notes or the Certificates to the extent, but only to the
extent, Lessor has actually paid funds to a taxing authority with respect to
such withholding taxes (and, if the Lessor receives a demand for such payment
from any taxing authority, the Lessee shall discharge such demand on behalf of
the Lessor);

          (g)(i) If a written claim is made against any Tax Indemnitee or if any
proceeding shall be commenced against such Tax Indemnitee (including a written
notice of such proceeding), for any Impositions, such Tax Indemnitee shall
promptly notify Lessee in writing and shall not take action with respect to such
claim or proceeding without the consent of Lessee for thirty (30) days after the
receipt of such notice by Lessee; provided, that, in the case of any such claim
or proceeding, if action shall be required by law or regulation to be taken
prior to the end of such 30-day period, such Tax Indemnitee shall, in such
notice to Lessee, inform Lessee, and no action shall be taken with respect to
such claim or proceeding without the consent of Lessee before the end of such
shorter period; provided, further, that the failure of such Tax Indemnitee to
give the notices referred to this sentence shall not diminish Lessee's
obligation hereunder except to the extent such failure materially adversely
affects Lessee in contesting all or part of such claim.

          (ii) If, within thirty (30) days of receipt of such notice from the
Tax Indemnitee (or such shorter period as the Tax Indemnitee has noticed Lessee
is required by law or regulation for the Tax Indemnitee to commence such
contest), Lessee shall request in writing that such Tax Indemnitee contest such
Imposition, the Tax Indemnitee shall, at the expense of Lessee, in good faith
conduct and control such contest (including, without limitation, by pursuit of
appeals) relating to the validity, applicability or amount of such Impositions
(provided, however, that (A) if such contest can be pursued independently from
any other proceeding involving a tax liability of such Tax Indemnitee, the Tax
Indemnitee, at Lessee's request, shall allow Lessee to conduct and control such
contest and (B) in the case of any contest that Lessee is not entitled to
control, the Tax Indemnitee may request Lessee to conduct and control such
contest if possible or permissible under applicable law or regulation) by, in
the sole discretion of the Person conducting and controlling such contest, (1)
resisting payment thereof, (2) not paying the same except under protest, if
protest is necessary and proper, (3) if the payment be made, using reasonable
efforts to obtain a refund thereof in appropriate administrative and judicial
proceedings, or (4) taking such other action as is reasonably requested by
Lessee from time to time.
<PAGE>

                                                                              30

          (iii)  The party controlling any contest shall consult in good faith
with the non-controlling party and shall keep the non-controlling party
reasonably informed as to the conduct of such contest; provided that all
decisions ultimately shall be made in the sole discretion of the controlling
party.  The parties agree that an Tax Indemnitee may at any time decline to take
further action with respect to the contest of any Imposition and may settle such
contest if such Tax Indemnitee shall waive its rights to any indemnity from
Lessee that otherwise would be payable in respect of such claim (and any future
claim by any taxing authority with respect to other taxable periods that are
based, in whole or in part, upon the resolution of such claim) and shall pay to
Lessee any amount previously paid or advanced by Lessee pursuant to this Section
12.2 by way of indemnification or advance for the payment of an Imposition, and
no other then future liability of the Lessee is likely with respect to such
Imposition.

          (iv) Notwithstanding the foregoing provisions of this Section 12.2, a
Tax Indemnitee shall not be required to take any action and Lessee shall not be
permitted to contest any Impositions in its own name or that of the Tax
Indemnitee unless (A) Lessee shall have agreed to pay and shall pay to such Tax
Indemnitee on demand and on an After Tax Basis all reasonable costs, losses and
expenses that such Tax Indemnitee actually incurs in connection with contesting
such Impositions, including, without limitation, all reasonable legal,
accounting and investigatory fees and disbursements, (B) in the case of a claim
that must be pursued in the name of an Tax Indemnitee (or an Affiliate thereof),
the amount of the potential indemnity (taking into account all similar or
logically related claims that have been or could be raised in any audit
involving such Tax Indemnitee for which Lessee may be liable to pay an indemnity
under this Section 12.2) is more than $25,000, unless the pursuit of such
contest is in a manner mutually satisfactory to the Tax Indemnitee and the
Lessee, but in no event shall such right prevent the Lessee from prosecuting or
continuing such contest, (C) the Tax Indemnitee shall have reasonably determined
that the action to be taken will not result in any material danger of sale,
forfeiture or loss of any piece of Equipment, or any part thereof or interest
therein, will not interfere with the payment of Rent, and will not result in
risk of criminal liability, (D) if such contest shall involve the payment of the
Imposition prior to the contest, Lessee shall provide to the Tax Indemnitee an
interest-free advance in an amount equal to the Imposition that the Tax
Indemnitee is required to pay (with no additional net after-tax cost to such Tax
Indemnitee), (E) in the case of a claim that must be pursued in the name of an
Tax Indemnitee (or an Affiliate thereof), Lessee shall have provided to such Tax
Indemnitee an opinion of independent tax counsel selected by the Lessee and
reasonably satisfactory to such Tax Indemnitee stating that a reasonable basis
exists to contest such claim (or, in the case of an appeal of an adverse
determination, an opinion of such counsel to the effect that there is
substantial authority for the position asserted in such appeal) and (F) no Event
of Default shall have occurred and be continuing.  In no event shall a Tax
Indemnitee be required to appeal an adverse judicial determination to the United
State Supreme Court.  In addition, a Tax Indemnitee shall not be required to
contest any claim in its name (or that of an Affiliate) if the subject matter
thereof shall be of a continuing nature
<PAGE>

                                                                              31

and shall have previously been decided adversely by a court of competent
jurisdiction pursuant to the contest provisions of this Section 12.2, unless
there shall have been a change in law (or interpretation thereof) and the shall
Tax Indemnitee have received, at the Lessee's expense, an opinion of independent
tax counsel selected by the Lessee and reasonably acceptable to the Tax
Indemnitee stating that as a result of such change in law (or interpretation
thereof), it is more likely than not that the Tax Indemnitee will prevail in
such contest.


                          SECTION 13.  MISCELLANEOUS

          13.1  Survival of Agreements.  The representations, warranties,
covenants, indemnities and agreements of the parties provided for in the

Equipment to the Trust, any disposition of any interest of the Trust in the
Equipment or any interest of the Investors in the Trust, the payment of the
Notes and any disposition thereof and shall be and continue in effect
notwithstanding any investigation made by any party and the fact that any party
may waive compliance with any of the other terms, provisions or conditions of
any of the Operative Agreements.  Except as otherwise expressly set forth herein
or in other Operative Agreements, the indemnities of the parties provided for in
the Operative Agreements shall survive the expiration or termination of any
thereof.

others that it has not retained or employed any broker, finder or financial
adviser to act on its behalf in connection with this Agreement, nor has it
authorized any broker, finder or financial adviser retained or employed by any
other Person so to act, except for the Arranger, the fees of which shall be paid
by the Lessee in accordance with the Fee Letter.  Any party who is in breach of
this representation shall indemnify and hold the other parties harmless from and
against any liability arising out of such breach of this representation.

hereunder by notice to each of the other parties hereto.

          13.4  Counterparts.  This Agreement may be executed by the parties
hereto in separate counterparts, each of which when so executed and delivered
shall be an original, but all such counterparts shall together constitute but
one and the same instrument.

          13.5  Amendments and Termination.  Neither this Agreement nor any of
the terms hereof may be terminated, amended, supplemented, waived or modified
except by an instrument in writing signed by the party against which the
enforcement of the termination, amendment, supplement, waiver or modification

writing by the Trust, both Investors, the Lessee, the Agent and the Lenders.
Notwithstanding the foregoing provisions to the contrary, in the case of the

          13.6  Headings, etc..  The Table of Contents and headings of the

          13.8  GOVERNING LAW.  THIS AGREEMENT SHALL BE GOVERNED BY, AND
CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.
<PAGE>

                                                                              34

          13.9  Severability.  Any provision of this Agreement that is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

          13.10  Liability Limited.  The Lessee, the Agent, the Lenders and
the Investors each acknowledge and agree that the Trust Company is (except as
otherwise expressly provided herein or therein) entering into this Agreement and
the other Operative Agreements to which it is a party (other than the Trust
Agreement), solely in its capacity as trustee under the Trust Agreement and not
in its individual capacity and that Trust Company shall not be liable or
accountable under any circumstances whatsoever in its individual capacity for or
on account of any statements, representations, warranties, covenants or
obligations stated to be those of the Trust, except for its own gross negligence
or willful misconduct and as otherwise expressly provided herein or in the other
Operative Agreements.

          13.11  Rights of Lessee.  Notwithstanding any provision of the
Operative Agreements, if at any time all obligations (i) of the Trust under the
Credit Agreement and the Security Documents and (ii) of the Lessee under the
Operative Agreements have in each case been satisfied or discharged in full,
then the Lessee shall be entitled to (a) terminate the Lease (to the extent not
previously terminated) and (b) receive all amounts then held under the Operative
Agreements and all proceeds with respect to the Equipment.  Upon the fulfillment
of the obligations contained in clauses (i) and (ii) above, the Lessor shall
transfer to the Lessee all of its right, title and interest in and to the
Equipment (to the extent not previously transferred to the Lessee in accordance
with the Lease) and any amounts or proceeds referred to in the foregoing clause
(b) shall be paid over to the Lessee.

          13.12  Further Assurances.  The parties hereto shall promptly cause
to be taken, executed, acknowledged or delivered, at the sole expense of the
Lessee (other than with respect to the removal of Lessor Liens), all such
further acts, conveyances, documents and assurances as the other parties may
from time to time reasonably request in order to carry out and effectuate the
intent and purposes of this Agreement, the other Operative Agreements and the
transactions contemplated hereby and thereby (including, without limitation, the
preparation, execution and filing of any and all Uniform Commercial Code
financing statements and other filings or registrations which the parties hereto
may from time to time request to be filed or effected).  The Lessee, at its own
expense, shall take such action as may be reasonably requested in order to
maintain and protect all security interests provided for hereunder or under any
other Operative Agreement.

                                                                              35

          13.13  Successors and Assigns.  This Agreement shall be binding upon
and inure to the benefit of the parties hereto and their respective successors
and assigns.

          13.14  No Representation or Warranty.  Nothing contained herein, in
any other Operative Agreement or in any other materials delivered to the Lessee
in connection with the transactions contemplated hereby or thereby shall be
deemed a representation or warranty by the Agent or the Arranger or any of their
Affiliates as to the proper accounting treatment or tax treatment that should be
afforded to the Lease and the Lessor's ownership of the Equipment and the Agent
expressly disclaims any representation or warranty with respect to such matters.

          13.15  Highest Lawful Rate.  It is the intention of the parties
hereto conform strictly to applicable usury laws and, anything herein to the
contrary notwithstanding, the obligations of the Lessee, the Lessor or the
Investors or any other party under any Operative Agreement, shall be subject to
the limitation that payments of interest or of other amounts constituting
interest shall not be required to the extent that receipt thereof would be in
excess of the Highest Lawful Rate, or otherwise contrary to provisions of law
applicable to the recipient limiting rates of interest which may be charged or
collected by the recipient.  Accordingly, if the transactions or the amount paid
or otherwise agreed to be paid for the use, forbearance or detention of money
under this Agreement, the Lease and any other Operative Agreement would exceed
the Highest Lawful Rate or otherwise be usurious with respect to the recipient
of any such amount, then, in that event, notwithstanding anything to the
contrary in this Agreement, the Lease or any other Operative Agreement, it is
agreed as follows as to the recipient of any such amount:

          (a   the provisions of this Section 13.15 shall govern and control
over any other provision in this Agreement, the Lease and any other Operative
Agreement and each provision set forth therein is hereby so limited;

          (b   the aggregate of all consideration which constitutes interest
that is contracted for, charged or received under this Agreement, the Lease, or
any other Operative Agreement shall under no circumstances exceed the maximum
amount of interest allowed by any Requirement of Law (such maximum lawful
interest rate, if any, with respect to such Lender herein called the "Highest
Lawful Rate"), and all amounts owed under this Agreement, the Lease and any
other Operative Agreement shall be held subject to reduction and (i) the amount
of interest which would otherwise be payable to the recipient hereunder and
under the Lease, the Loan Documents and any other Operative Agreement, shall be
automatically reduced to the amount allowed under any Requirement of Law and
(ii) any unearned interest paid in excess of the Highest Lawful Rate shall be
credited to the payor by the recipient (or, if such consideration shall have
been paid in full, refunded to the payee);

          (c   all sums paid, or agreed to be paid for the use, forbearance and
detention of the money under this Agreement, the Lease, or any other Operative
Agreement shall, to the extent permitted by any Requirement of Law, be
amortized, prorated, allocated and spread throughout the full term of such
indebtedness until payment in full so that the actual rate of interest is
uniform throughout the full term thereof; and

          (d   if at any time the interest, together with any other fees, late
charges and other sums payable pursuant to or in connection with this Agreement,
the Lease, and any other Operative Agreement executed in connection herewith or
therewith, and deemed interest under any Requirement of Law exceeds that amount
which would have accrued at the Highest Lawful Rate, the amount of interest and
any such fees, charges and sums to accrue to the recipient of such interest,
fees, charges and sums pursuant to the Operative Agreement shall be limited,
notwithstanding anything to the contrary in the Operative Agreement to that
amount which would have accrued at the Highest Lawful Rate for the recipient,
but any subsequent reductions, as applicable, shall not reduce the interest to
accrue pursuant to the Operative Agreement below the recipient's Highest Lawful
Rate until the total amount of interest payable to the recipient (including all
consideration which constitutes interest) equals the amount of interest which
would have been payable to the recipient (including all consideration which
constitutes interest), plus the amount of fees which would have been received
but for the effect of this Section 13.15.

           than a Borrower Default) will occur under any of the Operative
           Agreements as a result of the Advance requested by this Requisition.

              (b)  Attached to this Requisition is a schedule identifying the

     warranty contained in this Requisition or any untrue statement made in this
     Requisition, including, without limitation, Losses consisting of reasonable
     legal or other expenses incurred in connection with investigating,
     defending or participating in any legal proceeding relating to any of the
     foregoing (whether or not such indemnified person is a party thereto);
     provided, however, that no such indemnification will be required for any
     losses to the extent such losses arise solely out of the gross negligence
     or willful misconduct of such indemnified person.

           8.  Survival.  The agreements, statements, representation and
     warranties contained in this Requisition shall survive and remain effective
     until the Loans and all other obligations under the Credit Agreement and
     the other Operative Agreements are paid or otherwise satisfied in full by
